The study was undertaken to evaluate maternal, perinatal outcomes following transcervical intrapartum amnioinfusion in women with meconium-stained amniotic fluid. A prospective comparative study was conducted on 100 women with meconium-stained amniotic fluid in labor. Group A: study group (50 cases) received amnioinfusion. Group B: control group (50 cases) did not receive amnioinfusion. FHR monitoring was done using cardiotocography. Significant relief from variable decelerations was seen in 68.18 % cases in the amnioinfusion group as compared to 7.1 % cases in the control group. 78 % cases who were given amnioinfusion had vaginal delivery as compared to 18 % cases in the control group. Fourteen percent cases in the study group had cesarean delivery as compared to 68 % cases in the control group. Meconium aspiration syndrome was seen in six percent neonates in the study group as compared to 20 % in the control group. Two neonates died in the control group due to meconium aspiration syndrome. There was no maternal mortality or major maternal complication. Intrapartum transcervical amnioinfusion is valuable in patients with meconium-stained amniotic fluid.

Multiple control groups in case-control studies are used to control for different sources of confounding. For example, cases can be contrasted with matched controls to adjust for multiple genetic or unknown lifestyle factors and simultaneously contrasted with an unmatched population-based control group. Inclusion of different control groups for a single exposure analysis yields several estimates of the odds ratio, all using only part of the data. Here the authors introduce an easy way to combine odds ratios from several case-control analyses with the same cases. The approach is based upon methods used for meta-analysis but takes into account the fact that the same cases are used and that the estimated odds ratios are therefore correlated. Two ways of estimating this correlation are discussed: sandwich methodology and the bootstrap. Confidence intervals for the pooled estimates and a test for checking whether the odds ratios in the separate case-control studies differ significantly are derived. The performance of the method is studied by simulation and by applying the methods to a large study on risk factors for thrombosis, the MEGA Study (1999-2004), wherein cases with first venous thrombosis were included with a matched control group of partners and an unmatched population-based control group.

We evaluated the clinical and virological characteristics of hepatitis A virus infection in persons concomitantly infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). We enrolled 21 patients with acute hepatitis A and chronic hepatitis with no sign of liver cirrhosis, 13 patients who were positive for hepatitis B surface antigen (case B group), 8 patients who were anti-HCV positive (case C group), and 21 patients with acute hepatitis A without a preexisting liver disease (control A group). Two control groups of patients with chronic hepatitis B (control B group) or C (control C group) were also chosen. All control groups were pair-matched by age and sex with the corresponding case group. Fulminant hepatitis A was never observed, and hepatitis A had a severe course in 1 patient in the case B group and in 1 patient in the control A group. Both patients recovered. On admission, HBV DNA was detected in 1 patient in the case B group (7.7%) and in 13 patients (50%) in the control B group; HCV RNA was found in no patient in the case C group and in 16 patients (81.2%) in the control C group. Of 9 patients in the case B group who were followed up for 6 months, 3 became negative for hepatitis B surface antigen and positive for hepatitis B surface antibody, 2 remained positive for hepatitis B surface antigen and negative for HBV DNA, and 4 became positive for HBV DNA with a low viral load [corrected] Of 6 patients in the case C group who were followed up for 6 months, 3 remained negative for HCV RNA, and 3 had persistently low viral loads. Concomitant hepatitis A was always self-limited, associated with a marked inhibition of HBV and HCV genomes, and possibly had a good prognosis for the underlying chronic hepatitis.

Objective: To explore the effect of occupational exposure to glyphosate on hepatorenal function. Methods: 526 workers who were occupationally exposed to glyphosate from 5 glyphosate-producing factories were selected as cases; and another 442 administrative staffs who were not exposed to glyphosate were selected as controls from April to November, 2014. All the subjects accepted occupational health examination. The concentration level of glyphosate in the air of workshop was detected and the time weighted average concentration (TWA) was calculated. And analyze the difference of hepatorenal fuction between case group and control group. Result: The age of the subjects in the case and control groups were separately (35.6±10.3), (34.3±9.7) years old, with the length of working for (6.5±5.7), (7.7±6.8) years. The TWA of glyphosate in the case group was between <0.03-48.91 mg/m(3), with the geometric mean at 3.78 mg/m(3). The overall rates of abnormal hepatic and renal function in the case group were 14.4% (76 cases) and 16.2% (85 cases), respectively; while those were 5.0% (22 cases) and 4.8% (21 cases), respectively in control group, and the difference showed statistical significance ( P <0.05). When TWA reached <0.03-6.00 mg/m(3), the difference of hepatorenal fuction between case group and control group showed statistical significance, and the rates of abnormal hepatic and renal function was 8.0% (36/447) and 9.8% (44/447) respectively in case group. When cumulative exposure level reached <1.56-68.64 g, the difference of hepatorenal fuction between case group and control group showed statistical significance, and the rates increased to 9.2% (37/404) and 10.4% (42/404) respectively in group of cases. Conclusion: Glyphosate can affect the hepatic and renal function among occupational exposure population, and there was an association between the effect and the exposure dose.

We introduce a strategy for creating virtual control groups-cases generated through computer algorithms that, when aggregated, may serve as experimental comparators where live controls are difficult to recruit, such as when programs are widely disseminated and randomization is not feasible. We integrated and harmonized data from eight archived longitudinal adolescent-focused data sets spanning the decades from 1980 to 2010. Collectively, these studies examined numerous psychosocial variables and assessed past 30-day alcohol, cigarette, and marijuana use. Additional treatment and control group data from two archived randomized control trials were used to test the virtual control algorithm. Both randomized controlled trials (RCTs) assessed intentions, normative beliefs, and values as well as past 30-day alcohol, cigarette, and marijuana use. We developed an algorithm that used percentile scores from the integrated data set to create age- and gender-specific latent psychosocial scores. The algorithm matched treatment case observed psychosocial scores at pretest to create a virtual control case that figuratively "matured" based on age-related changes, holding the virtual case's percentile constant. Virtual controls matched treatment case occurrence, eliminating differential attrition as a threat to validity. Virtual case substance use was estimated from the virtual case's latent psychosocial score using logistic regression coefficients derived from analyzing the treatment group. Averaging across virtual cases created group estimates of prevalence. Two criteria were established to evaluate the adequacy of virtual control cases: (1) virtual control group pretest drug prevalence rates should match those of the treatment group and (2) virtual control group patterns of drug prevalence over time should match live controls. The algorithm successfully matched pretest prevalence for both RCTs. Increases in prevalence were observed, although there were discrepancies between live and virtual control outcomes. This study provides an initial framework for creating virtual controls using a step-by-step procedure that can now be revised and validated using other prevention trial data.

To explore and compare the effectiveness of two styles of case-based learning methods, unfolding nursing case and usual nursing case, implemented in lectures for developing nursing students' critical thinking ability. 122 undergraduate nursing students in four classes were taught the subject of medical nursing for one year. Two classes were randomly assigned as the experimental group and the other two the control group. The experimental group received the lectures presenting unfolding nursing cases and the control group was taught the usual cases. Nineteen case-based lectures were provided in 8 months in two semesters to each group. The two groups started with a similar level of critical thinking ability as tested by the instrument of Critical Thinking Disposition Inventory-Chinese version (CTDI-CV). After receiving 19 case-based learning lectures for 8 months, both groups of students significantly improved their critical thinking ability. The improvement in the experimental group was significantly higher than that in the control group (with the average total score of 303.77±15.24 vs. 288.34±13.94, p<0.05). The experimental group also had significantly better improvement in six out of seven dimensions whereas the control group showed improvement in only three out of seven dimensions of CTDI-CV. The study suggests the feasibility of implementing case-based learning in lectures. Unfolding nursing cases appear to be significantly more effective than the usual nursing cases in developing undergraduate nursing students' critical thinking ability in the subject of medical nursing. Further research can implement the unfolding nursing cases in other nursing subjects. Copyright © 2016 Elsevier Ltd. All rights reserved.

Balancing the subject composition of case and control groups to create homogenous ancestries between each group is essential for medical association studies. We explored the applicability of single-tube 34-plex ancestry informative markers (AIM) single nucleotide polymorphisms (SNPs) to estimate the African Component of Ancestry (ACA) to design a future case-control association study of a Brazilian urban sample. One hundred eighty individuals (107 case group; 73 control group) self-described as white, brown-intermediate or black were selected. The proportions of the relative contribution of a variable number of ancestral population components were similar between case and control groups. Moreover, the case and control groups demonstrated similar distributions for ACA <0.25 and >0.50 categories. Notably a high number of outlier values (23 samples) were observed among individuals with ACA <0.25. These individuals presented a high probability of Native American and East Asian ancestral components; however, no individuals originally giving these self-described ancestries were observed in this study. The strategy proposed for the assessment of ancestry and adjustment of case and control groups for an association study is an important step for the proper construction of the study, particularly when subjects are taken from a complex urban population. This can be achieved using a straight forward multiplexed AIM-SNPs assay of highly discriminatory ancestry markers.

To discuss the significance of amnioinfusion and amniotic fluid exchange under continuous internal fetal heart rate (FHR) monitoring for management of fetal distress during labor. 136 cases with frequent variable deceleration (VD) and meconium stained amniotic fluid during labor were divided into two groups: the study group (68 cases) and the control group (68 cases). The former were treated by amnioinfusion and amniotic fluid exchange, while oxygen inhalation, change of body position, and intravenous infusion for the control group. In the study group, VD disappeared or relieved in 62 cases obviously, and the efficacy rate reached 91.2% (62/68). 48 cases with II degree meconium stained amniotic fluid were treated by amniotic fluid exchange, amniotic fluid became clear or turned to I degree stained in 39 cases. In the control group, VD relieved in 20 cases, the efficacy rate was 19.4%, significantly lower than that of the study group (P < 0.01). In the study group, cesarean section rate was 14.7% neonatal asphyxia 7.4% while they were 47.1% and 48.5% in the control group respectively (P < 0.01; P < 0.01). Neonatal pneumonia caused by meconium aspiration occurred in 13 cases, meconium aspiration syndrome (MAS) 8 cases, with 5 newborns died in the control group, while there was no neonatal death in the study group. There was no significant difference on puerperal morbidity between the 2 groups (P > 0.05). Amnioinfusion and AF exchange during labor are one of the effective treatment methods for fetal distress and prevention for MAS.

Antimicrobial exposure remains an important risk factor for developing Clostridium difficile infection (CDI). Efficient method to identify antibiotics associated with CDI is important for formulating strategies to curtail their use. As a prelude to a more extensive Agency for Healthcare Research and Quality-funded project (Evaluation & Research on Antimicrobial Stewardship's Effect on Clostridium difficile), we undertook an exploratory evaluation to determine a resource-efficient method for identifying antibiotic targets for antimicrobial stewardship interventions. The study compared a series of 6 focused case-control studies. Cases consisted of patients with laboratory-confirmed CDI admitted from July-October 2009. Controls were selected from patients without CDI hospitalized during the same period. Five groups of controls were matched to cases (2:1 ratio) using group-specific matching criteria, including admission date, age, type of admission, length of stay (LOS) to discharge, and/or LOS to CDI diagnosis. The final control group was selected from patients who received antibiotics during hospitalization. Data, including demographics and antibiotic usage, were compared between case and control groups. A total of 126 cases were matched to 6 groups of 252 controls. For control groups 1-5, the use of piperacillin and tazobactam, ceftriaxone or cefepime, ciprofloxacin or moxifloxacin, intravenous vancomycin, azithromycin, and antibiotics of last resort were significantly more frequent in case than control patients. For the final control group, the associations between ceftriaxone or cefepime, and ciprofloxacin or moxifloxacin use and CDI no longer persisted. This could in part be explained by differences in comorbidities between case and control patients even with stringent matching criteria. Use of a simple matching strategy to conduct case-control studies is an efficient and feasible compromise strategy, especially in resource-limited settings, to identify high-risk antibiotics associated with CDI.

To explore the efficacy and safety of continuously released prostaglandin E(2) (PGE(2)) suppository-propess used for induction of term pregnancy. A multicenter, prospective, case control clinical study was carried out, propess was used in 100 cases as study group, the suppository without PGE(2) was used in 49 cases as control group. The cervical maturity (by Bishop scoring), the time to labor starting, membrane rupture and delivery, the application of oxytocin, ceserean section rate, fetal and neonatal condition were compared between 2 groups after inserting of the suppository. At the same time, side effects caused by propess were investigated. Bishop score was increased >or= 2 points in 93% cases, >or= 3 points in 87% cases in study group, whereas only 4% cases whose Bishop score increased >or= 2 points in control group. The time to labor starting, membrane rupture, and delivery was shortened obviously in study group than that in control group after inserting suppository. The application of oxytocin was much less in study group, cesarean section rate was reduced in study group (32% vs 61%). There was no significant difference between 2 groups in fetal and neonatal conditions. The overstimulation of uterine contraction and mild gastrointestinal tract reaction occurred in 3 cases and 2 cases respectively in study groups. Propess can be used for induction of term pregnancy effectively and safely.

Microvascular complications in type 2 diabetes (T2DM), including diabatic retinopathy (DR), diabetic kidney disease (DKD), diabetic peripheral neuropathy (DPN) are the leading causes of visual loss, end-stage renal disease or amputation, while the current therapies are still unsatisfactory. Chinese medicine (CM) has been widely used for treating diabetic mellitus. However, most of the previous studies focused on the single complication. The role of CM treatment in T2DM patients with 2 or multiple microvascular complications is not clear. To appraise the curative effect of CM in T2DM patients with 2 or multiple microvascular complications, and to compare the effects of stationary treatment and individualized treatment in T2DM patients with microvascular complications. This trial will be an 8-center, randomized, controlled study with 8 parallel groups. A total of 432 patients will be randomized to 8 groups: DR study group (32 cases) and a corresponding control group (32 cases), DR+DKD study group (64 cases) and a corresponding control group (64 cases), DR+DPN study group (64 cases) and a corresponding control group (64 cases), DR+DKD+DPN study group (56 cases) and a corresponding control group (56 cases). The control group will receive stationary treatment, and the study group will receive individualized treatment based on CM syndrome differentiation in addition to stationary treatment. The study duration will be 50 weeks, comprising a 2-week run-in period, 24 weeks of intervention, and 24 weeks of follow-up. The outcomes will assess efficacy of treatment, improvement in CM symptoms, safety assessments, adherence to the treatment, and adverse events. This study will provide evidence of evidence-based medicine for CM treatment in two or multiple microvascular complications caused by T2DM. (Registration No. ChiCTR-IPR-15007072).

Vaginal microecological environment is an important factor of recurrent vulvovaginal candidiasis (RVVC). This study was undertaken to investigate dynamic changes of vaginal microecosystem in patients with RVVC. Four hundred patients with VVC and 400 healthy women of reproductive age who admitted to the hospital from January 2012 to December 2013 were evaluated retrospectively. Vaginal microecological factors were evaluated before and after treatment until no recurrence, including vaginal cleanliness, white blood cells, Lactobacillus, Lactobacillus classification, bacteria density, flora diversity, Nugent scores, etc. The grouping was done according to the recurrence of the disease. Every time after treatment, the relapsing patients were defined as case group and the cured patients without recurrence were defined as control group. The differences in the results between the case and the control groups were analyzed by t test. With the development of RVVC, the ages of all case groups were lower than the corresponding control groups. In different stages of the disease, the bacteria density of the case groups and their corresponding control groups had no significant difference (P > 0.05). Most of the microecological indicators of the first occurring group were significantly different (P < 0.05) from that of the control group. In the recurrence groups, only a few indicators were significantly different from the control groups. The values of all vaginal microecological indicators (except Lactobacillus) of all case groups were higher than that of the control groups. The values of Lactobacillus of all RVVC case groups were lower than that of the RVVC control groups. There were vaginal microecological imbalances in all developing stages of RVVC. As for vaginal flora, diverse sorts changed to normal Lactobacillus dominantly with the development of RVVC. In the first occurrence of RVVC, after antifungal treatment, Lactobacillus is suggested to be timely supplemented to restore vaginal microecological balance.

Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively ( P <0.01). Ten cases who resisted the control treatment were then treated by electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

Chronic exposure to n-hexane can lead to peripheral neuropathy that no effective treatment regimen could be applied presently. This study investigated whether myelin protein zero (P0) protein and its antibody could be used to distinguish n-hexane intoxication and protect workers from peripheral neuropathy. We compared P0 protein and its antibody among three levels of n-hexane-exposed groups, which included 18 patients with n-hexane-induced peripheral neuropathy as case group, 120 n-hexane-exposed workers as n-hexaneexposed control group, and 147 non-hexane-exposed participants used as control group. ELISA method was applied to detect P0 protein and its antibody. P0 protein in serum was significantly higher in the case group and n-hexane-exposed control group in comparison with the control group (P < 0.01). Compared with the n-hexane-exposed control group, the case group also had significant increase of P0 protein (P < 0.01). After 6 months therapy, P0 protein was observed to decrease significantly in the case group (P < 0.01). The P0 antibody in serum was significantly higher in the n-hexane-exposed control group than in the control group (P < 0.01), but not significantly different between cases and controls. P0 antibodies in serum may be a short-term effect biomarker for n-hexane exposure. P0 protein in serum may be an early effective biomarker for peripheral nerve neuropathy and its biological limit value needs investigation in the future study.

To investigate the effect of Huangqi injection on the short-term prognosis in childhood with acute lymphoblastic leukemia (ALL). A retrospective analysis was performed on the clinical data of 105 children newly diagnosed with ALL between January 2009 and December 2012. These children were randomly divided into treatment group (18 low-risk cases, 7 medium-risk cases, and 24 high-risk cases) and control group (21 low-risk cases, 7 medium-risk cases, 28 high-risk cases). Both groups were given remission induction therapy based on the levels of risk. Throughout the remission induction therapy, the treatment group also received Huangqi injection (0.5-1.0 mL/kg per day) by intravenous infusion, while the control group was given 0.9% sodium chloride injection instead. The two groups were compared in terms of distribution of prognostic factors and complete remission (CR) rate after remission induction therapy, as well as the incidence of minimal residual disease (MDR) (≥ 10(-4) and < 10(-4)) among all patients in the two groups on day 19 of remission induction therapy and among B-ALL patients in the two groups when achieving a CR at the end of remission induction therapy. Of the 105 children with ALL, 99 had B-ALL, and 6 had T-ALL. There were no significant differences in the distribution of prognostic factors between the two groups (P>0.05). The overall CR rate of 105 patients was 79%; there was no significant difference in CR rate between the treatment and control groups (82% vs 77%; P>0.05); also, no significant differences were found between the two groups in the CR rates among high-, medium-, and low-risk cases (P>0.05). On day 19 of remission induction therapy, the incidence of MRD≥10(-4) in the treatment group was significantly lower than that in the control group (69% vs 95%; P<0.05); among 80 children with B-ALL who achieved a CR (43 cases in the control group and 37 cases in the treatment group), the incidence of MRD≥10-4 was significantly lower in the treatment group than in the control group (27% vs 58%; P<0.05); in both circumstances above, the high- and low-risk cases in the treatment group had a significantly lower incidence of MRD≥10(-4) than the control group (P<0.05). Huangqi injection combined with chemotherapy has an enhanced anti-tumor effect and can improve the short-term prognosis and clinical outcome in children with ALL.

Background Very little is known about possible association of nevi and melasma. The study objective was to determine if there is an association between melasma and existence of different kinds of nevi. Methods In a case-control study, 120 female melasma patients referred to dermatology clinic of Ardabil and 120 patients referred to other specialty clinics who lacked melasma were enrolled after matching for age. Number of different types of nevi including lentigines and melanocytic nevi were compared between case and control group patients. Data were entered into the computer and analyzed by SPSS 13 statistical software. Results Mean number of lentigines was 25.5 in melasma group compared to 8 in control group(P < 0.01). Mean number of melanocytic nevi was 13.2 in cases compared to 2.8 in control group(P < 0.001). Multivariate analysis showed that existence of freckles, lentigines and more than three melanocytic nevi were positively related to developing melasma. The chance of melasma increased up to 23 times for patients having more than three melanocytic nevi. Congenital nevi were observed among 10% both in case and control groups. Campbell de morgan angiomas were seen among 26 patients(21.8%) in case group compared to 6 patients(5%) in control group. Conclusion Existence of lentigines and melanocytic nevi increases chance of having melasma PMID:18680608

Background The aim of this study was to assess the preventive value of active ankle movements in the formation of lower-extremity deep venous thrombosis (DVT), attempting to develop a new method for rehabilitation nursing after orthopedic surgery. Material/Methods We randomly assigned 193 patients undergoing orthopedic surgery in the lower limbs into a case group (n=96) and a control group (n=97). The control group received routine nursing while the case group performed active ankle movements in addition to receiving routine nursing. Maximum venous outflow (MVO), maximum venous capacity (MVC), and blood rheology were measured and the incidence of DVT was recorded. Results On the 11th and 14th days of the experiment, the case group had significantly higher MVO and MVC than the control group (all P<0.05). The whole-blood viscosity at high shear rate and the plasma viscosity were significantly lower in the case group than in the control group on the 14th day (both P<0.05). During the experiment, a significantly higher overall DVT incidence was recorded in the control group (8 with asymptomatic DVT) compared with the case group (1 with asymptomatic DVT) (P=0.034). During follow-up, the case group presented a significantly lower DVT incidence (1 with symptomatic DVT and 4 with asymptomatic DVT) than in the control group (5 with symptomatic DVT and 10 with asymptomatic DVT) (P=0.031). Conclusions Through increasing MVO and MVC and reducing blood rheology, active ankle movements may prevent the formation of lower-extremity DVT after orthopedic surgery. PMID:27600467

Guidelines for the management of vaginal discharge mention Candida albicans, Trichomonas vaginalis, bacterial vaginosis, Chlamydia trachomatis and Neisseria gonorrhoeae as causes and do not recommend full microbiological culture. The role of non-group B beta-haemolytic streptococci in vaginal cultures is unclear, except for group A streptococci that are known to cause vulvovaginitis in children. In a case-control study, we investigated the association between non-group B beta-haemolytic streptococci and vulvovaginitis in adult women. Cases were women with recurrent vaginal discharge from whom a sample was cultured. Controls were asymptomatic women who consented to submitting a vaginal swab. Group A streptococci were isolated from 49 (4.9%) of 1,010 cases and not from the 206 controls (P < 0.01). Isolation rates of group C, F and G streptococci were low and did not differ statistically between cases and controls. Group A beta-haemolytic streptococci are associated with vaginal discharge in adult women. The other non-group B streptococci require more study. For the adequate management of vaginal discharge, culturing is necessary if initial treatment fails. Guidelines should be amended according to these results.

To study human teratogenic potential of furazidine treatment during pregnancy. Pair analysis of cases with congenital abnormalities and matched population controls. The Hungarian Case-Control Surveillance of Congenital Abnormalities. 38,151 pregnant women who had newborn infants without any defects (population control group) and 22,865 pregnant women who had newborns or fetuses with congenital abnormalities between 1980 and 1996. In the case group, 157 (0.7%) and in the control group, 254 (0.7%) pregnant women were treated with furazidine. The case-control pair analysis did not indicate a teratogenic potential of furazidine use during the second to third months of gestation, i.e. in the critical period for major congenital abnormalities. Treatment with furazidine during pregnancy did not show teratogenic risk to the fetus.

To determine eosinophil and mast cell populations in gastric and duodenal mucosal biopsies of adults with nonulcer dyspepsia (NUD) as compared to non-dyspeptic adults. A case control study. Shahid Sadoughi University of Medical Sciences, Yazd, Iran, from January 2010 to June 2011. A total of 52 (25 non-ulcer dyspeptic patients as case and 27 non-dyspeptic patients as control) patients underwent endoscopy. All patients had a minimum of 2 forceps biopsies obtained from stomach and duodenum. Routine histological evaluation was performed and additionally evaluated to determine eosinophil and mast cell counts. The statistical analysis was performed on SPSS version 17.0, using Mann-Whitney test with significance at p < 0.05. The mean age in the case and control groups was 31.72 ± 12.17 and 35.74 ± 12.42 years respectively. The median eosinophil density in gastric mucosa in case group was 5.0 (ranging from 1 to 20) and 4.0 in control group (ranging from 0 to 16; p = 0.140). The median eosinophil density in duodenal mucosa in case group was 16.0 (ranging from 2 to 24) and 13 in control group (ranging from 2 to 45; p = 0.147). The median mast cell density in gastric mucosa in case group was 4.0 (ranging from 0 to 33) and 4.0 in control group (ranging from 0 to 26; p = 0.827). The median mast cell density in duodenal mucosa in case group was 4.0 (ranging from 0 to 31) and 3.0 in control group (ranging from 1 to 23; p = 0.704). The frequency of Helicobacter pylori infection in both the groups was similar. Although there were not statistically significant differences in eosinophil and mast cell densities between case and control groups, there was a trend toward mild eosinophilia in gastric and duodenal mucosa. The specific role of eosinophils and mast cells in NUD is yet to be completely defined.

To study the influence of cow's milk protein allergy (CMPA) on the diagnosis of functional gastrointestinal diseases (FGID) based on the Rome IV standard in infants and young children. A total of 84 children aged 1 month to 3 years who were diagnosed with CMPA were enrolled as the case group, and 84 infants and young children who underwent physical examination and had no CMPA were enrolled as the control group. The pediatricians specializing in gastroenterology asked parents using a questionnaire for the diagnosis of FGID based on the Rome IV standard to assess clinical symptoms and to diagnose FGID. The case group had a significantly higher incidence rate of a family history of allergies than the control group (P<0.05). In the case group, 38 (45%) met the Rome IV standard for the diagnosis of FGID, while in the control group, 13 (15%) met this standard (P<0.05). According to the Rome IV standard for FGID, the case group had significantly higher diagnostic rates of reflex, functional diarrhea, difficult defecation, and functional constipation than the control group (P<0.05). The children who were diagnosed with FIGD in the control group were given conventional treatment, and those in the case group were asked to avoid the intake of cow's milk protein in addition to the conventional treatment. After 3 months of treatment, the case group had a significantly higher response rate to the treatment than the control group (P<0.05). In infants and young children, CMPA has great influence on the diagnosis of FGID based on the Rome IV standard. The possibility of CMPA should be considered during the diagnosis of FGID.

The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students' epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based learning and the control group received traditional instruction. At the experimental group, life cases were presented with small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students' epistemological beliefs and attitudes toward chemistry.

To study the curative effect and safety of rotatory manual reduction with forceps holder and retrograde percutaneous pinning transfixation in treating clavicular fracture. All 201 cases of clavicular fractures were randomly divided into treatment group (101 cases) and control group (100 cases). The treatment group was treated by rotatory manual reduction with forceps holder and retrograde percutaneous pinning transfixation. The control group was treated by open reduction and internal fixation with Kirschner pin. All cases were followed up for 4 to 21 months (mean 10.6 months). SPSS was used to analyze clinic healing time of fracture and shoulder-joint function in both two groups. After operation, 101 cases of treatment group achieved union of fracture and the clinical healing time was 28 to 49 days (mean 34.5+/-2.7 days). In control group,there were 4 cases with nonunion of fracture,the other 96 cases were union,the clinical healing time was 36 to 92 days (mean 55.3+/-4.8 days). The excellent and good rate of shoulder-joint function was 100% in treatment group and 83% in control group. By t-test and chi2-test, there was significant difference between the two groups in curative effect (P<0.05). Rotatory manual reduction with forceps holder and retrograde pinning transfixation can be used in various kinds of clavicular shaft fracture, with many virtues such as easy operation, reliable fixation, short union time of fracture, good functional recovery of shoulder-joint and no incision scar affecting appearance.

Background: A lot of studies have shown periodontal diseases as a risk factor for adverse pregnancy outcomes. The association between periodontitis and preeclampsia has been studied recently with controversy. Considering the importance of preventing preeclampsia as a dangerous and life-threatening disease in pregnant women, the present study was carried out. Methods: Two hundred and ten pregnant women participated in this case-control study (105 controls & 105 cases) during years 2007 and 2008. Preeclamptic cases were defined as blood pressure ≥140/90mmHg and proteinuria +1. Control group were pregnant women with normal blood pressure without proteinuria. Both groups were examined during 48 hours after child delivery. Plaque Index (PLI), Pocket Depth (PD), Clinical Attachment Level (CAL), Bleeding On Probing (BOP), Gingival Recession (GR) were measured on all teeth except for third molars and recorded as periodontal examination. Data was analyzed using t-test, chi-square, and Mann-Whitney U statistical tests. Results: There was no significant difference between the two study groups for PD. CAL, GR, BOP significantly increased in the case group (P< 0.02). This study showed that preeclamptic cases were more likely to develop periodontal disease (P< 0.0001). Eighty three percent of the control group and 95% of the case group had periodontal disease (P< 0.005) which had shown that preeclamptic cases were 4.1 times more likely to have periodontal disease (OR= 4.1). Conclusion: Preeclamptic cases significantly had higher attachment loss and gingival recession than the control group. PMID:23113094

Triglycerides (TGs) are proatherogenic lipoproteins involving the risk of coronary heart disease (CHD), while apolipoprotein A5 (APOA5) and apolipoprotein C3 (APOC3) are main lipoproteins composing TG-rich lipoproteins. In this study, we aim to explore the correlation of CHD with APOA5 -1131 T > C and APOC3 -455 T > C single nucleotide polymorphisms (SNPs). A sum of 210 CHD patients, hospitalized between Jan. 2013 and Mar. 2015 at China-Japan Union Hospital, Jilin University, were selected as our case group and 223 healthy individuals who had physical examination at same hospital at the same period were selected as control group. The frequency distribution of genotypes of APOA5 -1131 T > C and APOC3 -455 T > C SNPs were measured by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The Stata 12.0 software was utilized for statistical analyses. There was no significant difference on age and sex between case and control group (P > 0.05). History of smoking, drinking, hypertension and diabetes mellitus, body mass index and levels of TG and fasting blood sugar in case group were shown to be higher than control group (P < 0.05), while levels of total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol in case group were lower than control group (P < 0.05). Both CC and TC' + CC frequencies of APOA5 -1131 T > C and APOC3 -455 T > C in case group were higher compared to control group (both P < 0.05). Additionally, T allele frequencies of the two SNPs in case group were lower than control group, while C allele in case group has higher frequencies compared to control group (both P < 0.05). The results of meta-analysis under allele and dominant models showed that APOA5 -1131 T > C and APOC3 -455 T > C SNPs are likely to increase the risk of CHD (both P < 0.05). APOA5 -1131 T > C and APOC3 -455 T > C SNPs may play potent roles in the development and progression of CHD.

This study was carried out in a Anti-Retroviral Therapy Clinic and TB center of a tertiary level hospital to find out socio-demographic correlates of HIV/TB individuals and risk factors of HIV/TB co-infection in Indian context. It is a case-control study comprising 420 subjects, 3 groups of 140 each. For a case group of HIV-TB co-infected subjects, two control groups, one comprising HIV patients (not having TB), and the other TB patients (not having HIV). Majority 267 (63.6%) males, 100 (71.4%) in case group (HIV/ TB), 74 (52.9%) in control group 1 (TB) and 93 (66.4%) in control group 2 (HIV). Mean (+/-SD) age of case-group was 34.91 (+/- 8.57) years. New TB cases were 213 (76.1%), more among control-group 1, compared to case-group. Multivariate analysis showed that risk of co-infection was 1.94 times higher among individuals aged >35 years. Difference statistically significant amongst those who were not on ART than who were on ART (p < 0.001). Those with CD4 counts <200 had 1.85 times risk of TB. Smokers had 1.92 times risk of TB. Co-infection higher in males, in age group 35-44 years, urban area, lower educational status and lower socioeconomic class. Current history of smoking significantly associated with co-infection. HIV status during TB infection was detected in 1/4th of study subjects. History of TB symptoms in family significantly associated with co-infection.

To compare the structural and clinical outcomes after arthroscopic rotator cuff repair (ARCR) of a case group aged 70 and above with those of a control group younger than 70, with the 2 groups matched for sex and tear size. The case group, comprising 53 patients 70 or older, and the control group, comprising 159 patients younger than 70, all received ARCR to 1 shoulder with symptomatic full-thickness rotator cuff tear. The case and the control subjects, who were matched for sex and tear size to minimize bias related to tendon healing, received ARCR during the same period. The mean age was 71.8 ± 2.6 years in the case group and 59.3 ± 7.1 years in the control group. The minimum follow-up period was 1 year in both groups. Cuff integrity was evaluated using ultrasonography. Structural and clinical outcomes of the 2 groups were compared. Regarding structural outcomes, the complete healing, partial-thickness retear, and full-thickness retear rates were 66% (35/53), 15% (8/53), and 19% (10/53) in the case group, and 68% (108/159), 19% (30/159), and 13% (21/159), respectively, in the control group. The 2 groups had no significantly different retear rates (P = .52). Regarding clinical outcomes, the mean improvements in range of motion, pain, muscle strength, and age- and sex-matched Constant scores were not significantly different between the 2 groups (P > .37). The preoperative tear size was significantly associated with retear in both studied groups (P = .02). The clinical and structural outcomes of ARCR in patients 70 or older with symptomatic full-thickness rotator cuff tear are comparable with those in patients younger than 70 with at least 1-year follow-up. Preoperative tear size, a biological factor, is a strong predictor for retear. Level III, a retrospective comparative (case-control) study. Copyright © 2018 Arthroscopy Association of North America.

We investigated the use of mobile or cordless phones and the risk for malignant brain tumors in a group of deceased cases. Most previous studies have either left out deceased cases of brain tumors or matched them to living controls and therefore a study matching deceased cases to deceased controls is warranted. Recall error is one issue since it has been claimed that increased risks reported in some studies could be due to cases blaming mobile phones as a cause of the disease. This should be of less importance for deceased cases and if cancer controls are used. In this study brain tumor cases aged 20-80 years diagnosed during 1997-2003 that had died before inclusion in our previous studies on the same topic were included. Two control groups were used: one with controls that had died from another type of cancer than brain tumor and one with controls that had died from other diseases. Exposure was assessed by a questionnaire sent to the next-of-kin for both cases and controls. Replies were obtained for 346 (75%) cases, 343 (74%) cancer controls and 276 (60%) controls with other diseases. Use of mobile phones gave an increased risk, highest in the >10 years' latency group yielding odds ratio (OR) = 2.4, and 95% confidence interval (CI) = 1.4-4.1. The risk increased with cumulative number of lifetime hours for use, and was highest in the >2,000 h group (OR = 3.4, 95% CI = 1.6-7.1). No clear association was found for use of cordless phones, although OR = 1.7, 95% CI = 0.8-3.4 was found in the group with >2,000 h of cumulative use. This investigation confirmed our previous results of an association between mobile phone use and malignant brain tumors. Copyright 2010 S. Karger AG, Basel.

If variation in procedure times could be controlled or better predicted, the cost of surgeries could be reduced through improved scheduling of surgical resources. This study on the impact of similar consecutive cases on the turnover, surgical, and procedure times tests the perception that repeating the same manual tasks reduces the duration of these tasks. We hypothesize that when a fixed team works on similar consecutive cases the result will be shorter turnover and procedure duration as well as less variation as compared with the situation without a fixed team. Case-control study. St Franciscus Hospital, a large general teaching hospital in Rotterdam, the Netherlands. Two procedures, inguinal hernia repair and laparoscopic cholecystectomy, were selected and divided across a control group and a study group. Patients were randomly assigned to the study or control group. Preparation time, surgical time, procedure time, and turnover time. For inguinal hernia repair, we found a significantly lower preparation time and 10 minutes less procedure time in the study group, as compared with the control group. Variation in the study group was lower, as compared with the control group. For laparoscopic cholecystectomy, preparation time was significantly lower in the study group, as compared with the control group. For both procedures, there was a significant decrease in turnover time. Scheduling similar consecutive cases and performing with a fixed team results in lower turnover times and preparation times. The procedure time of the inguinal hernia repair decreased significantly and has practical scheduling implications. For more complex surgery, like laparoscopic cholecystectomy, there is no effect on procedure time.

Abortion, spontaneous or induced, is a common complication of pregnancy and exploration of available and safe regimens for medical abortion in developing countries seems crucial. The present study was aimed to assess the effect of letrozole in combination with misoprostol in women eligible for legal therapeutic abortion with gestational age ≤14weeks. This clinical randomized trial was conducted on 78 women who were candidate of medical abortion and eligible for legal abortion with gestational age ≤14 weeks that were randomly divided into two groups of case and controls. Case group received daily oral dose of 10mg letrozole for three days followed by vaginal misoprostol. In control group the patients received only vaginal misoprostol. The rate of complete abortion, induction-of-abortion time, and side-effects were assessed. Complete abortion was observed in 30 patients (76.9%) in case group and 9 (23.1%) cases were failed. In control group there was 16 (41.03%) complete abortions and 23 (58.97%) cases were failed to abort. Patients with gestational age of between 6 and 10 weeks did not show significant difference in both groups (P=0.134). Regarding pregnancy remnants there were significant differences between two groups (P=0.034). The time form admission to discharge in case groups were significantly shorter than those in control group (P=0.001). The indication for curettage in case group was significantly less than control group (P=0.001). A 3-day course of letrozole (10mg/daily) followed by misoprostol was associated with a higher complete abortion and lower curettage rates and reduction in time from admission to discharge in women with gestational age ≤14 weeks compared to misoprostol alone.

To explore the differences of the trophoblast cell function in first trimester between natural pregnancy and pregnancy after IVF-ET therapy. 102 cases with twin to singleton fetal reduction after IVF-ET treatment from July 2010 to August 2013 in Peking University Third Hospital were involved in analysis, and eight specimens were obtained from this group. 10 natural-pregnancy cases undergoing artificial abortion with unwanted pregnancy were recruited as control. Semi-quantitative immunohistochemical method was used to detect the expression of EGFR, Bcl-2, tubulin-α, metallothionein and AFP in villi in both groups. Of the 102 cases, 14 cases (13.73%) were aborted. Preterm birth occurred in seven cases (7.86%). Low birth weight occurred in three patients (3.37%), and extremely low birth weight occurred in four cases (4.49%). The expression of EGFR, tubulin-α, Bcl-2, and metallothionein in the IVF-ET group was significantly lower than that in the control group (P<0.05). However, AFP expression was significantly higher in IVF-ET group than in control group (P<0.05). In IVF-ET group, the miscarriage case had weaker EGFR, tubulin-α, and metallothionein expression than full-term pregnancy; the early preterm labor case had weaker Bcl-2, tubulin-α, and metallothionein expression; and velamentous cord insertion case had weaker tubulin-α expression. The trophoblast cell function of IVF-ET group in first trimester is different from control group in proliferation, invasion, apoptosis and vascular development, and optimal pregnancy outcome depends on the self-healing balance of trophoblast cells.

Screw-plates disassembly incidence after pertrochanteric fracture (PF) amounts to 1 and 16% among the elderly population. The main occurrence is early cervical screw cut-out. The population at highest risk of disassembly remains difficult to identify. The correlation between femoral offset loss and disassembly occurrence has never been surveyed. A radiological prognosis score for screw plate disassembly was defined to reflect trochanteric impaction (TI); it was based on a femoral offset ratio. Our single-centre retrospective case-control study surveyed patients suffering from Dynamic Hip Screw (DHS, Synthes ® ) disassembly following osteosynthesis of non-pathological osteoporotic PF between 2004 and 2014. All cases were categorised by age and gender and paired to three patients in the control group. The primary endpoint was TI measurement, corresponding to offset loss on the operated hip compared to healthy hip offset and expressed as a percentage. The measurement was done on an immediate postoperative X-ray. The secondary endpoints were tip apex distance (TAD) measurement, Ender and AO classifications, as well as postoperative weight-bearing prescription. Twenty-three cases and 69 controls were surveyed. The case group's average age was 87; 70% of the cases were women. The main disassembly occurrence delay was after 27 days. Average TI was 26% within the patients global group and 12% within the control group (p < 10 -5 ). Over a 21% impaction percentage, disassembly occurrence represents a greater risk: OR = 21.95% CI [5.4-104.3], p < 10 -5 . Ender 3 type fractures were the most frequent indication for surgery within the case group. Average TAD was 20 mm within the case group, and 17 mm within the control group (p = 0.03). The weight-bearing prescription rate was 52% within the control group and 21% within the case group (p = 0.014). 14.5% of the control group had a TI > 21%. Using the offset ratio tool, TI measurement was associated with a greater risk of DHS disassembly when it was higher than 21%. The exclusive use of a DHS device does not seem optimal for a TI > 21%. Weight-bearing may be prescribed for all the patients with a TI < 21%, provided good implant positioning is secured.

To explore the effectiveness of the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments to treat acute complete acromioclavicular dislocations. Between January 2008 and April 2012, 66 patients with acromioclavicular dislocation were treated with the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments in 32 cases (experimental group) and with the clavicular hook plate in 34 cases (control group). There was no significant difference in gender, age, injured side, the cause of injury, and the time from injury to operation between 2 groups (P > 0.05). Visual analogue scale (VAS), Constant shoulder scores, and coracoid clavi-cledistance (CC. Dist) were measured at preoperation and at 2 years after operation. Signal/noise quotiem (SNQ) was measured by MRI at 2 years after operation. The operation complications were observed. The patients of 2 groups obtained primary healing of incision. The morbidity of complication in experimental group (12.5%, 4/32) was significantly lower than that in control group (91.2%, 31/34) (Χ2 = 40.96, P = 0.00). All the cases were followed up 2.8 years on average (range, 2 to 4 years). VAS scores and CC.Dist significantly decreased at 2 years after operation when compared with preoperative values in the 2 groups (P < 0.05). VAS scores and CC.Dist of the experimental group were significantly lower than those in the control group (P < 0.05). According to Constant shoulder scores at 2 years after operation, the results were excellent in 19 cases, good in 11 cases, and general in 2 cases with an excellent and good rate of 93.75% in the experimental group; the results were excellent in 7 cases, good in 8 cases, general in 16 cases, and poor in 3 cases with an excellent and good rate of 44.11% in the control group; and significant difference was shown between 2 groups (t = 2.30, P = 0.03). SNQ was significantly lower in experimental group than in control group at 2 years after operation (t = 55.03, P = 0.00), indicating that ligament healing was better in experimental group than control group. Compared with simple clavicular hook plate fixation, the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments is successful in treating acute complete acromioclavicular dislocations, with the advantages of higher ligament healing, less complication, and early improvement of shoulder functions.

The aim of the present study was to investigate the correlation between Klotho gene polymorphisms andcalcium oxalate stones in Xinjiang Uyghur people. We compared 128 patients with calcium oxalate stones (case group) and 94 healthypeople (control group), detected the genotype and allele distributions of single-nucleotide polymorphisms (SNPs)of the Klotho gene (rs3752472, rs650439, and rs1207568) by reverse transcription polymerase chain reaction. The distributions of the genotype and allele frequencies of the SNPs were consistent with the Hardy-Weinberg equilibrium in the two groups. There were statistically significant differences between the genotype andallele distributions of rs3752472 between the case and control groups; the allele frequencies in the case/controlgroups were C = 240 (93.7%)/151 (80.3%) and T = 16 (6.3%)/37 (19.7%). There was no statistically significantdifference in the genotype distribution of rs650439 between the case and control groups, but there was a differencein the allele distribution; the allele frequencies in the case/control groups were A = 202 (78.9%)/143 (57.2%) andT = 54 (21.1%)/107 (42.8%). There were no statistically significant differences in genotype and allele distributionsbetween the case and control groups of rs1207568; the allele frequencies in the case/control groups were C = 194(71.3%)/145 (77.1%) and T = 78 (28.7%)/43 (22.9%). In rs3752472, the risk for patients with the C and A allelesincreased by 3.675 and 2.799 times, respectively. The rs3752472 and rs650439 SNPs are related to the risk of calcium oxalate stones in Xinjiang Uyghurpeople, and might be one of the risk factors.

Case-control studies are often performed to estimate postlicensure vaccine effectiveness (VE), but the enrollment of controls can be challenging, time-consuming, and costly. We evaluated whether children enrolled in the same hospital-based diarrheal surveillance used to identify rotavirus cases but who test negative for rotavirus (test-negative controls) can be considered a suitable alternative to nondiarrheal hospital or community-based control groups (traditional controls). We compared calculated VE estimates as a function of varying values of true VE, attack rates of rotavirus and nonrotavirus diarrhea in the population, and sensitivity and specificity of the rotavirus enzyme immunoasssay. We also searched the literature to identify rotavirus VE studies that used traditional and test-negative control groups and compared VE estimates obtained using the different control groups. Assuming a 1% attack rate for severe rotavirus diarrhea, a 3% attack rate for severe nonrotavirus diarrhea in the population, a test sensitivity of 96%, and a specificity of 100%, the calculated VE estimates using both the traditional and test-negative control groups closely approximated the true VE for all values from 30% to 100%. As true VE decreased, the traditional case-control approach slightly overestimated the true VE and the test-negative case-control approach slightly underestimated this estimate, but the absolute difference was only ±0.2 percentage points. Field VE estimates from 10 evaluations that used both traditional and test-negative control groups were similar regardless of control group used. The use of rotavirus test-negative controls offers an efficient and cost-effective approach to estimating rotavirus VE through case-control studies.

To analyze the possible association of maternal age with the risk of all congenital abnormalities (CAs) in a population-based large case-matched control data set. The Hungarian Case-Control Surveillance of Congenital Abnormalities included 21,494 cases with isolated CA and their 34,311 matched controls. First the distribution of maternal age groups in 24 CA-groups and their matched controls was compared. In the second step, young (19 years or less) and advanced (35 years or more) age groups were compared. Finally, the subgroups of neural-tube defects, congenital heart defects and abdominal wall's CA were evaluated separately. A higher risk of gastroschisis, congenital heart defects, particularly left-sided obstructive defects, undescended testis and clubfoot was found in the youngest age group (19 years or less) of cases. The higher proportion of pregnant women with advanced age (i.e. 35 years or more) showed only a borderline excess in cases with clubfoot. The so-called U-shaped risk of maternal age distribution was found in cases with clubfoot and in the total group of isolated CAs. The maternal age is a contributing factor to the origin of some isolated CAs mainly in young pregnant women.

To observe the therapeutic effect of acupuncture plus acupoint-injection on greater occipital neuralgia. The 84 cases of greater occipital neuralgia were randomly divided into two groups, with 42 cases in the treatment group treated by acupuncture plus acupoint-injection, and 42 cases in the control group treated with oral administration of carbamazepine. The total effective rate was 92.8% in the treatment group and 71.4% in the control group. The difference in the total effective rate was significant (P < 0.05) between the two groups. Acupuncture plus acupoint-injection is effective for greater occipital neuralgia, better than the routine western medication.

To examine the association between fetal nutritional status and overweight and obesity in their adulthood and to provide evidence for formulation of the strategy on preventing low birth weight. Using data from 2002 Nationwide Nutrition and Health Survey to set up a case-control method in order to compare body mass index(BMI), prevalence of overweight and obesity as well as to calculate odds ratio of overweight and obesity of case group compared with control group. Three case groups were selected from those who were born in 1959, 1960,1961 respectively, and the controls were those who were born in 1964. The health consequence of being famines on adulthood was evident in women. Means of BMI in women were significantly higher in three case groups than that in control group(P<0.01). After adjustment on geographic regions, the prevalence of overweight in women was significantly higher in three case groups than that in control group(P< 0.01). The prevalence rates of obesity were significantly higher in 1959, 1960 groups than 1964 group(P< 0.05). The odds ratios of overweight of women in three case groups were 28.9% (95% CI:1.063-1.565), 37.2% (95% CI:1. 136-1.658) and 35.2% (95% CI: 1. 103-1.657) respectively, all higher than that in the control group. The odds ratios of obesity of women born in 1959, 1960 groups were 46.5% (95% CI: 1.088-1.972) and 39.6% (95% CI: 1.039- 1.876) respectively, higher than that in the 1964 group. However, such differences were not found in men. Higher risks of overweight and obesity in women were caused by malnutrition during their fetal lives. A strategy on preventing low birth weight should be formulated by the government to prevent the chronic disease in adulthood.

To study the ultra structural changes in bladder musculature in cases of BPE and their clinical relevance. In this descriptive longitudinal, controlled, observational study patients were enrolled into three groups, group 1, group 2A and group 2B. Control group (group-1) consisted of age matched normal male patients, who underwent surveillance or diagnostic cystoscopy for microscopic hematuria or irritative symptoms. Case group (group-2) comprised of patients with BPE, undergoing TURP. Case group (group-2) was further classified into: Category 2A (patients not on catheter) and cat-egory 2B (patients on catheter). All relevant clinical parameters like IPSS, prostate size, Qmax, PVR were recorded. Cystoscopy and bladder biopsy were performed in all patients. Various ultrastructural parameters like myocytes, fascicular pattern, interstitial tissue, nerve hypertrophy and cell junction pattern were analyzed under electron microscope and they were clinically correlated using appropriate statistical tests. Control group had significant difference as compared to case group in terms of baseline parameters like IPSS, flow rate and prostate size, both preoperatively and postoperatively, except for PVR, which was seen only preoperatively. There was statistically significant difference in ultrastructural patterns between case and control group in all five electron microscopic patterns. However, no significant difference was found between the subcategories of case groups. BPE is responsible for ultra structural changes in detrusor muscle and these changes remain persistent even after TURP. Nerve hypertrophy, which was not thoroughly discussed in previous studies, is also one of the salient feature of this study. Copyright® by the International Brazilian Journal of Urology.

We examined IgG antibody seroprevalence and risk factors for anti-Toxoplasma gondii and anti-Borrelia sp. in schizophrenic patients. This case-control study included 30 schizophrenic patients and 60 healthy individuals. Serological analyses were identified by using ELISA technique. In the case group the Toxoplasma seropositivity was 33.3% and Borrelia seropositivity was 13.3%, while in the control group the Toxoplasma positivity was 21.7% and Borrelia seropositivity was 15.0%. There was no significant difference with regard to seroprevalence between the groups (P = 0.232; P = 0.832, respectively). There was statistically significant difference between case and control groups related to hand and kitchen utensil hygiene after dealing with raw meat (P = 0.001). Our data showed the rate of Toxoplasma antibodies was higher in the case group, while the rate of Borrelia antibodies was higher in the control group. In both groups the high rates of seropositivity for Toxoplasma gondii and Borrelia sp. is thought to be due to neglect of personal hygiene. The present study also is the first to examine the association between Borrelia sp. and schizophrenia. Further studies are needed to determine whether there is an association between Borrelia sp. and schizophrenia or not.

To investigate the influence factors of birth defects. The congenital malformational fetuses born from 13 week of gestation to 7 days after birth were selected as the study group between April 1st, 2009 and March 31st, 2010. The health born fetuses were set as control in the same period. Case-control and the three-level of monitor network of birth defects were used in the study in the participating 75 hospitals (Qingdao Women and Children's Medical Center, Affiliated Hospital of Medical College Qingdao University, Qingdao Municipal Hospital, etc.). The study and control group's parents were interviewed by an uniformed questionnaire which was designed specially with influence factors of birth defects. (1) There are 466 congenital malformational fetuses in the total of 77 231 fetuses collected in 75 hospitals. The congenital malformational rate accounts for about 6.034‰. The top six defect diseases were congenital heart disease (112 cases), total harelip (cleft lip; cleft lip with palate: 85 cases), polydactyly (53 cases), neural tube defects (38 cases), congenital hydrocephalus (37 cases) and limb reduction defect (27 cases) in turn, which amounts to 353 cases (54.48%, 353/648). (2) Their mother education level in the birth-defect group (25.6%) were significantly lower than that in control group (30.0%, P<0.05). (3) The rate of passive smoking, drinking, raising pets of the parents in birth-defect group were significantly higher than that in control group (P<0.05). (4) The rate of exposure to harmful chemical and physical factors of mothers in birth defects group (13.9% and 20.5%, respectively) was higher than that in control group (1.1% and 11.7%, respectively), the difference between which were significant (P<0.01). The rate of disease (34.3%), fever (13.1%), taking drugs (33.8%) in pregnancy period in birth defect group were higher than that in control group (13.5%, 1.5% and 9.9%, respectively), the difference between which were significant (P<0.01). The rate of bad moral irritation to the mother in pregnancy in birth defect group (11.3%) was significantly higher than that in control group (1.4%, P<0.01). (5) There were 19 cases (2.9%, 19/648) with family heredity medical history in birth defect group, but there were none in the control group, the difference between which were significant (P<0.01). There were 89 cases (13.7%, 89/648) with unusual birth history of their mothers in birth defect group, but there were 31 cases (4.8%, 31/650) in control group, the difference between which were significant (P<0.01). (6) Conditional Logistic Regression model was used for univalent and multivariate analysis. The results showed that main influence factors were identified as having important effect on birth defects, including mothers' exposure to harmful chemical factors (OR=13.46), disease (OR=3.37), taking drugs (OR=2.20), exposure to bad moral irritation (OR=5.44), food-choosy (OR=1.90), anemia (OR=1.52) in gestational period, polyembryony (OR=4.40), father drinking (OR=1.55). While it was protective factors to supplement microelements such as the calcium iron and nutrient, etc.in pregnancy period (OR=0.45). First, the main birth defects were congenital heart disease, total harelip(cleft lip; cleft lip with palate), polydactyly, neural tube defects, congenital hydrocephalus and limb reduction defect in turn. Second, the main influence factors identified as having important effect on birth defects were mothers' exposure to harmful chemical factors, ill, taking drugs, exposure to bad moral irritation, food-choosy, anemia in gestational period, polyembryony, father drinking. But it is protective factors to supplement microelements such as the calcium iron and nutrient, etc. in pregnancy period. Finally, it is the important part to prevent the birth defects by reducing and controlling dangerous factors in pregnancy period.

The clinical evidence of neurological menifestations associated with asphyxia is described as hypoxic ischaemic encephalopathy (HIE). A variety of metabolic problems are present in asphyxiated newborns including hypoglycemia, hypocalcemia, hypomagnesemia and others metabolic abnormalities. Some of these biochemical disturbances may trigger seizure or potentiate further brain damage. This cross sectional case-control study was done in Mymensingh Medical College Hospital, to identify the association of hypoglycemia, hypocalcemia, hypomagnesemia in neonates with perinatal asphyxia. Study period was six months. Sample size was 60. Among total sample 30 term asphyxiated newborns of <24 hours age were case and equal number term healthy newborns <24 hours age were control. The main clinical presentations were delayed cry after birth along with respiratory distress, convulsion and absence of cry in asphyxiated newborns. Major physical findings were cyanosis, convulsion and tachypnoea in asphyxiated group. The mean value of serum calcium level was significantly lower in asphyxiated newborns (7.37 ± 0.10mg/dl) than control value (8.04±0.09mg/dl). Hypocalcemia was found among 23.33% babies in case group. On the contrary, hypocalcemia was found in single baby among control group. The mean value of serum magnesium was significantly lower in asphyxiated newborns (1.83 ± 0.04mg/dl) than control value (1.96 ± 0.05mg/dl). Hypomagnesemia was found among 3(10%) newborns but none was found among control group. Hypoglycemia was found in 7(23.33%) cases though the mean value of blood glucose was higher in case group (5.72 ± 0.62mmol/l) than control group (4.87 ± 0.15mmol/l) difference was not statistically significant. Combined hypoglycemia, hypocalcemia and hypomagnesemia were found in 1(3.33%) case; combined hypoglycemia and hypocalcemia were found in 2(6.67%) cases; and combined hypocalcemia and hypomagnesemia were found in 1(3.33%) case. During the study period, 3(10.0%) cases were expired but no death occurred among control group. This study shows isolated or combined hypoglycemia, hypocalcemia, hypomagnesemia are frequently found in newborns with perinatal asphyxia. So, it is necessary to monitor blood glucose, serum calcium and also serum magnesium among asphyxiated newborns for proper management.

Congenital hypothyroidism (CH) is caused by thyroid dysgenesis and dyshormonogenesis. Evidence suggests the presence of genetic factors in both types of pathogenesis. We investigated whether an increased incidence of thyroid abnormalities could be shown by ultrasonography among first-degree relatives of children with CH. In this case-control study the presence of both developmental and non-developmental thyroid abnormalities was studied among first-degree relatives of CH patients and healthy children. Assessments included neck ultrasonography and thyroid function tests. The data obtained from parents, siblings and children were compared in the case and control groups. In the case group, 92 patients, 172 parents and 57 siblings, and in the control group, 82 healthy children, 160 parents and 39 siblings were studied. Thyroid developmental abnormalities were more prevalent among parents (3.5 vs. 0%, p = 0.03) and siblings (10.5 vs. 0, p = 0.01) of CH patients than the control group. Non-developmental abnormalities were not significantly different between the case and control groups (17 vs. 13%, p = 0.3). Thyroid developmental abnormalities were more prevalent among parents and siblings of CH patients than the control group, confirming the familial component of this entity. Copyright 2008 S.

Effects of human chorionic gonadotropin combined with clomiphene on serum E 2 , FSH, LH and PRL levels in patients with polycystic ovarian syndrome were analyzed. 90 patients with polycystic ovarian syndrome treated from January 2015 to March 2016 were randomly and evenly divided into control group and observation group. Patients in the control group were only treated with clomiphene. On the basis of the treatment in control group, human chorionic gonadotropin was added in the treatment of observation group. The changes of E 2 , FSH, LH, PRL levels were compared between two groups before and after the treatment. Clinical curative effects of patients in the two groups was evaluated. Adverse reactions during treatment in two groups were observed and recorded. The incidence of adverse reactions was calculated. Serum E 2 , FSH, LH and PRL levels in the two groups decreased significantly after treatment compared with that before treatment. The difference is statistical significant ( P < 0.05). After the treatment, E 2 , FSH, LH and PRL levels in the observation group were lower than that in the control group and the difference is statistical significant ( P < 0.05). Total effective rate was 64.44% in the control group and 93.33% in the observation group. There were statistically significant difference in clinical curative effects in the two groups ( P < 0.05). Different degrees of adverse reactions were found in both groups during treatment, such as nausea, vomiting, anorexia, liver dysfunction. There were 2 cases of nausea, 2 cases of vomiting, 3 cases of anorexia and 1 case of liver dysfunction from the 45 patients in control group. The total incidence of adverse reactions was 17.78% (8/45). There were 1 case of nausea, 1 case of vomiting, 1 case of anorexia and no liver dysfunction from the 45 patients in observation group. The total incidence of adverse reactions was 6.67% (3/45). The total incidence of adverse reactions in the observation group was significantly higher than that in the control group and the difference was not statistically significant ( P > 0.05). Combined use of human chorionic gonadotropin can significantly reduce serum E 2 , FSH, LH and PRL levels, improve clinical curative effects and reduce the incidence of adverse reactions. Human chorionic gonadotropin has high application value on the treatment of polycystic ovary syndrome.

To determine the therapeutic value of selective salpingography (SSG) for infertile women with patent fallopian tubes. Retrospective, case-control analysis. University Hospital, infertility clinic. Infertile cases with patent tubes documented by hysterosalpingography (HSG) or by HSG followed by laparoscopic examination (n = 80). Hysteroscopic SSG. Patency rate of tubes by SSG. Pregnancy rate following SSG. Eighty cases were divided into the study group (SSG performed, 37 cases) and the case-control group (SSG not performed, 43 cases). Successful SSG of at least one tube was obtained in all of 37 cases (100%) in whom SSG was attempted. A patency rate of 95.9% was documented in the 73 cannulated tubes of these cases. The total subsequent pregnancy rate (48.6%) within 12 months of follow-up after SSG was significantly higher than that (11.6%) obtained in the control group (p < 0.001). The cumulative pregnancy rate in the study group was also significantly higher than that in the control group (p < 0.001). The findings of the present study encourage the application of SSG to infertile women, either as a sole therapeutic approach or in association with other methods of assisted reproductive technology, even if their fallopian tubes are shown to be patent by HSG.

2011-06-01
A total of 80 cases of advanced schistosomiasis were selected and divided into an experiment group and a control group, 40 cases each group, by the random sampling method. The patients in the experiment group were administered with Jian-gan-le, and the patients in the control group received compound purple granules. In the experiment group, the curative rate was 25.0%, the improving rate was 70.0%, the inefficacy rate was 5%, and the efficiency rate was 95.0%. In the control group, the curative rate was 12.5%, the improving rate was 75%, the inefficacy rate was 12.5%. There was no statistic difference between the 2 groups (P all > 0.05). The expense was cheaper in the experiment group than in the control group.

In order to provide a scientific basis for rational use of antibiotics, we studied and compared the therapeutic effects of step-down and step-up antibiotic treatment schemes in children with lobar pneumonia. Eighty cases of children with lobar pneumonia were enrolled in this study and were randomly divided into two groups: The observation group and the control group, with 40 cases in each group. In the observation group, there were 23 cases with mild and 17 cases with severe lobar pneumonia, and in the control group, 25 were mild and 15 were severe cases. Patients in the control group were treated with antibiotics using step-up therapy method, while patients in the observation group were treated using step-down antibiotic therapy. Our results showed no significant differences in white blood cell (WBC) reduction rate, the course of antibiotic treatment, disappearance time of pulmonary rales and total efficiency in children with mild lobar pneumonia in the observation group after 72 h of treatment. The level of high-sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) in the observation group were significantly lower. After 72 h of treatment of children with severe lobar pneumonia in the observation group, the rate of WBC reduction accelerated significantly. Compared to the patients in the control group, the course of antibiotic treatment and disappearance time of pulmonary rales were shortened significantly, while the total efficiency of treatment was improved considerably in the observation group. Also in the observation group, hs-CRP and PCT levels were significantly lower than that in the control group. In severe cases, step-down therapy showed a better result in relieving the inflammatory reactions. The disappearance time of pulmonary rales and the effective rate of treatment was significantly higher than those of step-up therapy. It was obvious that for children with severe lobar pneumonia, step-down therapy produced better results in relieving the inflammatory reaction.

Objective: To investigate the safety and efficacy of the Weitan Waifu patch on the postsurgical gastroparesis syndrome (PGS) of gastrointestinal cancer. Methods: The multi-center, double-blind, randomized controlled trial was conducted with superiority design. Patients with PGS of gastrointestinal cancer diagnosed in 4 AAA hospitals and the abdominal symptom manifested as cold syndrome by Chinese local syndrome differentiation were recruited. These patients were randomly divided into two groups according to 1∶1 proportion. Placebo or Weitan Waifu patch was applied in control group or intervention group, respectively, based on the basic treatments, including nutrition support, gastrointestinal decompression, promoting gastric dynamics medicine.Two acupuncture points (Zhongwan and Shenque) were stuck with placebo in control group or patch in treatment group. The intervention course was 14 days or reached the effective standard. Results: From July 15, 2013 to Jun 3, 2015, 128 participants were recruited and 120 eligible cases were included in the full analysis set (FAS), and 60 cases in each group. 88 cases were included in the per-protocol set (PPS), including 45 cases in the treatment group and 43 cases in the control group. In the FAS, the clinical effective rate in the treatment group was 68.3%, significantly superior than 41.7% of the control group ( P =0.003). The medium time of effective therapy in the treatment group was 8 days, significantly shorter than 10 days in the control group ( P =0.017). In the FAS, 3 adverse events occurred in the treatment group, including mild to moderate decrustation, pruritus and nausea. The incidence rate of adverse events was 5.0% (3/60) and these symptoms were spontaneously remitted after drug withdrawal. No severe adverse events were observed in the control group. There was no significant difference between these two groups ( P =0.244). Conclusion: Weitan Waifu patch is a safely and effectively therapeutic method for patients with PGS (cold syndrome) of gastroenterological cancer. Trial registration: International Standard Randomized Controlled Trial Number Register, ISRCTN18291857.

To develop a receiver operating characteristic (ROC) curve of glycosylated hemoglobin (HbA1c) for diagnosing diabetes mellitus within a chronic disease management system. A case-control study including medical records from January 1, 1997, to December 31, 2005, was conducted at the Sioux Falls Veterans Affairs Medical Center. Medical records for the case group (patients with diabetes) were selected based on 1 of 3 criteria: International Classification of Diseases, Ninth Revision, Clinical Modification or Current Procedural Terminology codes specific for type 1 and type 2 diabetes; patients' use of medications (oral hypoglycemic agents, antidiabetes agents, or insulin); or results from random blood or plasma glucose tests (at least 2 measurements of blood glucose > or = 200 mg/dL). Records for the control group were selected based on patients having HbA1c measured, but not meeting the above diagnostic criteria for diabetes during the study period. Records for cases and controls were randomly frequency-matched, one-to-one. The control group was randomly divided into 5 sets of an equal number of records. Five sets of an equal number of cases were then randomly selected from the total number of cases. Each test data set included 1 case group and 1 control group, resulting in 5 independent data sets. In total, 5040 patient records met the case definition in the diabetes registry. Records of 15 patients who were prescribed metformin only, but did not meet any other case criteria, were reviewed and excluded after determining the patients were not diabetic. The control group consisted of 5 sets of 616 records each (totaling 3080 records), and the case group consisted of 5 sets of 616 records each (totaling 3080 records). Thus, each of the 5 independent data sets of 1 case group and 1 control group contained 1232 records. The case group was predominantly composed of white men (mean age, 69 years; mean body mass index, 31 kg/m2). Demographic data were similar for control patients. The ROC curve revealed that a HbA1c > or = 6.3% (mean + 1 SD) offered the most accurate cutoff value for diagnosing type 2 diabetes mellitus, with the following statistical values: C statistic, 0.78; sensitivity, 70%; specificity, 85%; and positive likelihood ratio, 4.6 (95% confidence interval, 4.2-5.0). A HbA1c value > or = 6.3% may be a useful benchmark for diagnosing diabetes mellitus within a chronic disease management system and may be a useful tool for monitoring high-risk populations.

This study was to research the incidence of infants with rotavirus enteritis combined with lactose intolerance and the clinical effect of low lactose milk powder for infantile rotavirus enteritis with lactose intolerance. The control groups were 126 cases of infants with diarrhea randomly collected from our hospital at the same period, which their rotavirus detection was negative. The observation group was 185 cases of infants with rotavirus, which was tested to be positive. Through the urine galactose determination, 62 cases of the control group were positive and 124 cases of the observation group were positive. Then 124 cases of infants with rotavirus combined with lactose intolerance were randomly divided into two groups. 60 cases in the control group were given rehydration, correction of acidosis, oral smecta, Intestinal probiotics and other conventional treatment, then continued to the original feeding method. While, 64 cases in the treatment group, on the basis of routine treatment, applied the low lactose milk feeding. To observe the total effective rate for the two groups. The incidence of lactose intolerance in children with rotavirus enteritis (67.03%) was significantly higher than that of children with diarrhea (49.2%), which was tested to be negative. And the difference was statistically significant (p<0.5). In the aspect of reducing the frequency of diarrhea, and diarrhea stool forming time, the treatment group has the obvious superiority. The total effective rate was 95.4% for treatment group, which was higher than that in the control group (76.7%), the difference was statistically significant (P<0.05). Infants with rotavirus enteritis was easier to merge with lactose intolerance. The low lactose milk powder could improve the therapeutic effectively and could reduce the duration of disease, and restored to normal diet for 2 weeks feeding time.

Case-control studies to quantify oral cholera vaccine effectiveness (VE) often rely on neighbors without diarrhea as community controls. Test-negative controls can be easily recruited and may minimize bias due to differential health-seeking behavior and recall. We compared VE estimates derived from community and test-negative controls and conducted bias-indicator analyses to assess potential bias with community controls. From October 2012 through November 2016, patients with acute watery diarrhea were recruited from cholera treatment centers in rural Haiti. Cholera cases had a positive stool culture. Non-cholera diarrhea cases (test-negative controls and non-cholera diarrhea cases for bias-indicator analyses) had a negative culture and rapid test. Up to four community controls were matched to diarrhea cases by age group, time, and neighborhood. Primary analyses included 181 cholera cases, 157 non-cholera diarrhea cases, 716 VE community controls and 625 bias-indicator community controls. VE for self-reported vaccination with two doses was consistent across the two control groups, with statistically significant VE estimates ranging from 72 to 74%. Sensitivity analyses revealed similar, though somewhat attenuated estimates for self-reported two dose VE. Bias-indicator estimates were consistently less than one, with VE estimates ranging from 19 to 43%, some of which were statistically significant. OCV estimates from case-control analyses using community and test-negative controls were similar. While bias-indicator analyses suggested possible over-estimation of VE estimates using community controls, test-negative analyses suggested this bias, if present, was minimal. Test-negative controls can be a valid low-cost and time-efficient alternative to community controls for OCV effectiveness estimation and may be especially relevant in emergency situations.

Purpose: Percutaneous hemodialysis thrombectomy causes subclinical pulmonary emboli without short-term clinical consequence; the long-term effects on the pulmonary arterial vasculature are unknown. We compared the prevalence of pulmonary hypertension between patients who underwent one or more hemodialysis access thrombectomy procedures with controls without prior thrombectomy.Methods: A retrospective case-control study was performed. Cases (n = 88) had undergone one or more hemodialysis graft thrombectomy procedures, with subsequent echocardiography during routine investigation of comorbid cardiovascular disease. Cases were compared with controls without end-stage renal disease (ESRD) (n = 100, group 1), and controls with ESRD but no prior thrombectomy procedures (n =more » 117, group 2). The presence and velocity of tricuspid regurgitation on echocardiography was used to determine the prevalence and grade of pulmonary hypertension; these were compared between cases and controls using the chi-square test and logistic regression.Results: The prevalence of pulmonary hypertension among cases was 52% (46/88), consisting of mild, moderate and severe in 26% (n = 23), 10% (n = 9) and 16% (n = 14), respectively. Prevalence of pulmonary hypertension among group 1 controls was 26% (26/100), consisting of mild, moderate and severe pulmonary hypertension in 14%, 5% and 7%, respectively. Cases had 2.7 times greater odds of having pulmonary hypertension than group 1 controls (p = 0.002). The prevalence of pulmonary hypertension among group 2 controls was 42% (49/117), consisting of mild, moderate and severe pulmonary arterial hypertension in 25% (n = 49), 10% (n = 12) and 4% (n = 5), respectively. Cases were slightly more likely to have pulmonary hypertension than group 2 controls (OR = 1.5), although this failed to reach statistical significance (p = 0.14).Conclusion: Prior hemodialysis access thrombectomy does not appear to be a risk factor for pulmonary arterial hypertension. Patients with ESRD are more likely to have pulmonary hypertension.« less

Urinary tract infection is the most common genitourinary disease in children so about 40% of the children with urinary tract infection suffering from reflux that caused some consequences such as pyelonephritis and kidney parenchymal injury. This research was conducted to compare the timing of voiding cystourethrogram (VCUG) in children with urinary tract infection in first week and after the first week of urinary tract infection. This research is a case-control study that both case and control groups include 208 children from 1 month to 12 years old with the complain of urinary tract infection. In case group, the VCUG was performed at the first week of infection and in control group, the VCUG was performed after the first week of infection. complication such as dysuria was observed in two-thirds of children who VCUG was performed during first week after urinary tract infection. Parents stress in case group was more than the other (P=0.015). For overall, the incidence of reflux in case and control groups was 49.5% and 50%, respectively. The mean of reflux grading in right kidney in case group was lower than control group resulting in significant differences between two groups. According to higher grade of stress in parents and complications due to VCUG at the first week of urinary tract infection, it is suggested that VCUG be conducted on selective patients in the hospital at the first week of urinary tract infection and during hospitalization.

To explore the relationship between mothers' body mass index (BMI) before pregnancy or weight gain during pregnancy and autism in children. From 2013 to 2014, the 181 children with autism and 181 healthy children matched by sex and age from same area were included in this study. According to mothers' BMI before pregnancy, the selected cases were divided into 3 groups: low, normal and high group. Then 3 groups were divided into 3 subgroups based on mother' s weight gain during pregnancy: low, normal and high group, according to the recommendations of Institute of Medicine. Logistic regression analysis and χ(2) test were conducted with SPSS 18.0 software to analysis the relationship between mothers' BMI before pregnancy or weight gain during pregnancy and autism in children. The age and sex distributions of case group and control group were consistent (χ(2)=0.434, P>0.05). The mothers' BMI before pregnancy of case group was higher than that of control group (χ(2)=9.580, P<0.05) ,which was (21.28±3.80) kg/m(2) for case group and (19.87±2.83) kg/m(2) for control group. The proportion of cases in high BMI group (10.5%) was much higher than that in control group (2.8%) . The risk of children with autism in high BMI group was 3.7 times higher than that in normal BMI group (OR=3.71, 95% CI: 1.34-10.24). In normal BMI group, the proportion of mothers who had excessive weight gain during pregnancy was higher in case group (44.1%) than in control group (33.9%). In high BMI group, the proportion of mothers who had excessive weight gain was higher in case group (52.6%) than in control group (20.0%) . In normal BMI group (χ(2) =8.690, P<0.05) and high BMI group (χ(2)=4.775, P<0.05), the weight gain during pregnancy was associated with autism in children. Logistic regression analysis showed that mothers' BMI before pregnancy (unadjusted OR=1.89, 95% CI: 1.26-2.85, adjusted OR=1.52, 95% CI: 1.19-2.27) and weight gain during pregnancy were the risk factors for autism in children (unadjusted OR=1.63, 95% CI: 1.08-1.25, adjusted OR=1.64, 95% CI: 1.21-2.21). Overweight or obesity before pregnancy and excessive weight gain during pregnancy were associated with autism in children, suggesting that women who plan to be pregnant should pay attention to body weight control.

Back pain is a challenge for case management but is a health insurance fund (HIF) that identifies high risk patients and includes them in a back pain assessment and a multimodal program cost-effective? Case managers of a HIF contacted selected patients and requested information on pain and current perspectives. Patients in the intervention group were offered a multimodal assessment and, if applicable, a multimodal treatment program. Control group patients received verbal or written (back book) information. Cost data were evaluated with respect to the interview data 1 year prior and 1 year afterwards. Of the 800 insured persons contacted 621 were nationwide, 88 were regional controls and 91 were intervention patients. Inability to work was still rising in all groups but less in the intervention group versus both control groups. Drugs, hospital as well as cure/adjuvant costs were less for intervention patients than in both control groups. The investment for the program was thus more than refinanced. Case management was well accepted but the intervention was in need of training for case managers and the specific diagnostic and treatment option regionally. The HIF was responsible for the study investment and project partners shared the training of the HIF regional case managers.

To discuss the application and clinical effect of damage control concept in the treatment of severe limbs fractures combining with multiple trauma. From July 2009 to July 2012, 30 patients with severe limbs fractures combining with multiple trauma were treated with the damage control concept, included 20 males and 10 females with an average age of (34.03 ± 12.81) years old ranging from 20 to 60 years old; the ISS averaged (35.00 ± 12.81) points (ranged from 26 to 54 points). And the control group also contained 30 patients with severe limbs fractures combining with multiple trauma treated by the traditional operation from June 2006 to June 2009, there were 23 males and 7 females with an average age of (34.23 ± 11.04) years old ranging from 18 to 65 years old. The ISS averaged (35.56 ± 11.04) points (ranged from 26 to 51 points). The age, gender, ISS, Gustilo classification, operation time, intraoperative blood loss, blood transfusion,postoperative complications and mortality rate were observed and compared. In the damage control concept group,there were 28 cases surviving and 2 cases (6.7%) death; 6 cases of postoperative complication included 2 cases of adult respiratory distress syndrome, 1 case of multiple organ failure, 1 case of disseminated intravascular coagulation and 2 cases of wound infection. In the control group, there were 22 cases surviving and 8 cases death(26.7%); 13 cases of postoperative complication included 4 cases of adult respiratory distress syndrome,2 cases of multiple organ failure, 2 cases of disseminated intravascular coagulation and 3 cases of wound infection. There were no statistically significant differences between two groups in age, gender, ISS, Gustilo classfication and complication (P > 0.05), however there were statistically significant differences in mortality rate, operation time, blodd loss, blodd transfusion between two groups (P < 0.05). Damage control concept is used to treat severe limbs fractures combining with multiple trauma which has the rapid and effective therapy, can improve survival rate and reduce complication.

Objective Post-tonsillectomy hemorrhage remains an important factor in determining the safety of performing tonsillectomy as a day case procedure. The aim of this study was to determine the safety of day case tonsillectomy by using combination method, cold dissection tonsillectomy and bipolar diathermy hemostasis. Methods A prospective randomized clinical study conducted on the patients who had undergone day case tonsillectomy (DCT). There were two groups (DCT and control group) each group consisting of 150 cases. Tonsillectomy was performed by using combination method; cold dissection and hemostasis was achieved by ligation of vessels with bipolar electerocautery. Findings We found 3 cases of post-tonsillectomy bleeding in DCT group and 4 cases in the control group. There was no statistically significant difference in the rate of post-operative hemorrhage between the two groups. Conclusion The findings suggest the safety of the combination of cold dissection tonsillectomy and bipolar diathermy hemostasis as day case tonsillectomy. PMID:23056702

Obesity is a growing problem in all countries which leads to various physical, psychological, and social problems. The present study aimed to assess depression in children and adolescents aged 10-18-year old compared with the control group. In a case-control study, from among the 10- to 18-year-old students of the five education districts of Isfahan, 100 people (50 girls and 50 boys) were selected as obese children with the Body Mass Index (BMI) of greater than 95(th) percentile for their age and gender and 100 others (50 girls and 50 boys) as the control group with the BMI of 5(th) to 85(th) percentile. The case and control groups were matched for age, gender, and socio-economic status. After calculating BMI based on weight (kg)/height(2) (meter), subjects were interviewed based on DSM IV criteria to diagnose clinical depression. The severity of children's depression was measured using standardized questionnaire. The mean age of the case group was 12.2 ± 1.86-years old and that of the control group 13.06 ± 2.25. They were, respectively, diagnosed with depression of 7% and 6%. The mean depression score of the case group was 11.7 ± 5.3 and that of the control group was 10.6 ± 6.03 with no statistical significance. Given our findings, the Jolly fat hypothesis applies to the case group. It seems that health policy-makers need to make intervention plans to change behavior; attitude, skill, and knowledge (BASK) of the public toward obesity and its long-term side-effects.

Matrix metalloproteinase-9 (MMP-9) plays an important role in inflammation and matrix degradation involved in atherosclerosis and plaque rupture. The T allele of rs3918242 has been reported to lead to a high promoter activity and associate with the extent of coronary artery disease (CAD). And some studies have reported that the G allele of rs17576 might be associated with CAD. The aim of this study was to assess the association between the polymorphisms of the MMP-9 gene and CAD in the Chinese Han population. This case-control study comprised 258 CAD cases and 153 controls from the Chinese Han Population. The genomic DNA of MMP-9 was isolated from whole blood. Polymerase chain reaction-based restriction fragment length polymorphism was used to determine the rs3918242 and rs17576 genotypes in the MMP-9 gene and the total serum levels of MMP-9 were measured using enzyme-linked immunosorbent assay in both case and control groups. Analysis of MMP-9 gene polymorphisms showed that the frequencies of the T allele and CT+TT genotypes of rs3918242 were significantly higher in the case group than in the control group (p<0.05). However, the distribution of variant genotypes of rs17576 did not differ between the case and control groups (p>0.05). The total serum level of MMP-9 was significantly higher in the case group than in the control group (p<0.05). The subjects carrying T alleles in the CAD group had higher average serum MMP-9 levels compared with CC genotypes (p<0.05). Our results suggest that the single-nucleotide polymorphism of rs3918242 in the MMP-9 gene is associated with CAD and high serum levels of MMP-9 are also associated with CAD in the Chinese Han population. Therefore, genetic variation of rs3918242 may participate in the development of CAD through influencing MMP-9 expression.

To find out a method for increasing clinical therapeutic effect on Bell palsy at acute stage. Ninety cases of Bell palsy were randomly divided into an observation group, a control group I and a control group II, 30 cases in each group. They were treated respectively with acupuncture plus exercise therapy, simple acupuncture therapy, and simple exercise therapy, and their therapeutic effects were observed. The cured rate was 66.7% in the observation group, 53.3% in the control group I and 46.70% in the control group II, the observation group being better than the two control groups (P<0.05). Acupuncture by stage combined with exercise therapy can increase the therapeutic effect on Bell palsy at acute stage, and it is a better therapy for Bell palsy.

It has been indicated that autologous hematopoietic stem cell transplantation (AHST) is a promising treatment to adults with type 1 diabetes, however, the application of AHST therapy to children with type 1 diabetes still needs more data. The aim of this study was to assess the clinical effect of immune intervention combined with AHST and conventional insulin therapy in the treatment of children with newly diagnosed type 1 diabetes. This 1:2 matched case-control study was comprised of 42 children who were newly diagnosed with type 1 diabetes in the Department of Endocrinology, Beijing Children's Hospital from 2009-2010. The case group included 14 patients, who were treated with AHST within the first 3 months after being diagnosed with diabetes at request of their parents during 2009-2010. The control group included 28 patients with newly diagnosed type 1 diabetes at the same period of hospitalization. We compared the baseline and follow-up data of them, including ketoacidosis onset, clinical variables (glycosylated hemoglobin (HbA1c), insulin dosage and serum C-peptide). The clinical characteristics of the patients was comparable between the case group and the control group. At 6-12 months ((10.7±4.2) months) after AHST treatment, we found 11 patients in the case group did not stop the insulin therapy, three cases stopped insulin treatment for 2, 3 and 11 months, respectively. No diabetic ketoacidosis (DKA) occurred after transplantation in all the patients in the case group. HbA1c in the control group was significant lower than that in the case group (P < 0.01), while the insulin dosage and serum C-peptide were not significant different between the two groups (P > 0.05). In order to eliminate the honeymoon effect, we performed final follow-up at the 3-5 years ((4.2±1.8) years) after AHST treatment, and found that HbA1c in the control group was still lower than that in the case group (P < 0.01); however, the insulin dosage and serum C-peptide were not significantly different between the two groups (P > 0.05). Moreover, the insulin dosage was not significant different from baseline to follow-up period in the case group. AHST treatment showed no advantage in effectiveness in children with newly diagnosed type 1 diabetes, both in insulin dose and long term blood glucose control.

The aim of this study was to assess the impact of extraction of third molars on the occurrence of temporo-mandibular disorders (TMD). A review of the literature and a case-control study have been conducted. The case-control study compares the frequency of extraction of third molars between the sample with TMD (case) and the sample without TMD (control). The proportion of patients who had undergone extractions of wisdom teeth was higher in the case group than in the control group. The difference was statistically significant when patients had undergone extraction of all four wisdom teeth or when the extraction of four wisdom teeth underwent in one sitting or under general anesthesia. The study of patients in case sample shows that all signs of TMD were more common in patients who had undergone extractions in several sessions and under local anesthesia. The temporomandibular joint sounds are significantly more frequent with local anesthesia. In the case group, 85 to 92% of patients have parafunctions and 5 to 11% have malocclusion. This demonstrates the multifactorial etiology of temporomandibular disorders. © EDP Sciences, SFODF, 2015.

To evaluate the effects of acupoint massage for postpartum hypogalactia in puerpera. A total of 60 puerpera of cesarean section were randomized into an observation group and a control group, 30 cases in each one. In the observation group, 2 cases were dropped out. Finally, there were 28 cases in the observation group and 30 cases in the control group. In the control group, the routine nursing after operation in obstetrics department was given, guiding maternal breastfeeding and postpartum health education. In the observation group, on the basis of the treatment as the control group, the corresponding acupoints were selected from the breast related meridians for massage. Acupoint massage was given since the 3rd day after operation, 8:00 am to 9:00 am, once a day, 1 min at one acupoint, continuously for 5 days. The lactation volume, breast filling, galactostasis and milk viscosity were compared in the parturient of the two groups. The clinical therapeutic effects were compared between the two groups. From the 1st to the 2nd days, the differences were not significant in lactation volume, breast filling and galactostasis score between the two groups (all P >0.05). From the 3rd to 5th days, the lactation volume, breast filling and galactostasis score in the observation group were all lower than those in the control group (all P <0.01). The difference in milk viscosity was not significant in the first 4 days between the two groups (all P >0.05). On the 5th day, the score of milk viscosity in the observation group was lower than that in the control group ( P <0.01). The cured rate was 64.3% (18/28) in the observation group, which was better than 13.3% (4/30) in the control group ( P <0.05). Massage at the acupoints from the breast related meridians effectively promotes the lactation secretion in puerpera of postpartum hypogalactia and alleviates breast distention.

To evaluate the effects of adding sublingual nitroglycerin to oxytocin, for delivery of retained placenta after vaginal delivery. The study was performed as a placebo controlled clinical trial on women who did not finish delivering placenta after 30 min of active management of the third stage of labor. In case group, 1 mg nitroglycerin and in the control group, placebo was prescribed sublingually. In total, 80 women finished the study. The number of manual removal of placenta did not show significant difference between the two groups [25 women (62.5%) in the case and 30 women (75%) in the control group, p = 0.335]. There was no significant difference between the two groups according to duration of the third stage of labor, hemoglobin index, decline in HB index >30% and maternal vital signs after treatment. There was no significant difference between the two groups according to adverse effects [eight women (20%) in the case group and four (10%) in the control group (p = 0.348)]. The sequential use of oxytocin and sublingual nitroglycerin could not lead to delivery of more placentas and did not reduce the necessity of manual removal of placenta in comparison with placebo.

A navigation system should improve the quality of a total knee prosthesis implantation in comparison to the classical, surgeon-controlled operative technique. The authors have implanted 40 knee total prostheses with an optical infrared navigation system (Orthopilot AESCULAP, Tuttlingen--group A). The quality of implantation was studied on postoperative long leg AP and lateral X-rays, and compared to a control group of 40 computer-paired total knee prostheses o the same model (Search Prosthesis, AESCULAP, Tuttlingen) implanted with a classical, surgeon-controlled technique (group B). An optimal mechanical femorotibial angle (3 degrees valgus to 3 degrees varus) was obtained by 33 cases in group A and 31 cases in group B (p > 0.05). Better results were seen for the coronal and sagittal orientation of both tibial and femoral components in group A. Globally, 26 cases of the group A and 12 cases of the group B were implanted in an optimal manner for all studied criteria (p < 0.01). The used navigation system allows a significant improvement of the quality of implantation of a knee total prosthesis in comparison to a classical, surgeon-controlled instrumentation. Long-term outcome could be consequently improved.

Simulation games are becoming increasingly popular in education, but more insight in their critical design features is needed. This study investigated the effects of fidelity of open patient cases in adjunct to an instructional e-module on students' cognitive skills and motivation. We set up a three-group randomized post-test-only design: a control group working on an e-module; a cases group, combining the e-module with low-fidelity text-based patient cases, and a game group, combining the e-module with a high-fidelity simulation game with the same cases. Participants completed questionnaires on cognitive load and motivation. After a 4-week study period, blinded assessors rated students' cognitive emergency care skills in two mannequin-based scenarios. In total 61 students participated and were assessed; 16 control group students, 20 cases students and 25 game students. Learning time was 2 h longer for the cases and game groups than for the control group. Acquired cognitive skills did not differ between groups. The game group experienced higher intrinsic and germane cognitive load than the cases group (p = 0.03 and 0.01) and felt more engaged (p < 0.001). Students did not profit from working on open cases (in adjunct to an e-module), which nonetheless challenged them to study longer. The e-module appeared to be very effective, while the high-fidelity game, although engaging, probably distracted students and impeded learning. Medical educators designing motivating and effective skills training for novices should align case complexity and fidelity with students' proficiency level. The relation between case-fidelity, motivation and skills development is an important field for further study.

Background Decades of research strongly suggest that the genetic etiology of autism spectrum disorders (ASDs) is heterogeneous. However, most published studies focus on group differences between cases and controls. In contrast, we hypothesized that the heterogeneity of the disorder could be characterized by identifying pathways for which individuals are outliers rather than pathways representative of shared group differences of the ASD diagnosis. Methods Two previously published blood gene expression data sets – the Translational Genetics Research Institute (TGen) dataset (70 cases and 60 unrelated controls) and the Simons Simplex Consortium (Simons) dataset (221 probands and 191 unaffected family members) – were analyzed. All individuals of each dataset were projected to biological pathways, and each sample’s Mahalanobis distance from a pooled centroid was calculated to compare the number of case and control outliers for each pathway. Results Analysis of a set of blood gene expression profiles from 70 ASD and 60 unrelated controls revealed three pathways whose outliers were significantly overrepresented in the ASD cases: neuron development including axonogenesis and neurite development (29% of ASD, 3% of control), nitric oxide signaling (29%, 3%), and skeletal development (27%, 3%). Overall, 50% of cases and 8% of controls were outliers in one of these three pathways, which could not be identified using group comparison or gene-level outlier methods. In an independently collected data set consisting of 221 ASD and 191 unaffected family members, outliers in the neurogenesis pathway were heavily biased towards cases (20.8% of ASD, 12.0% of control). Interestingly, neurogenesis outliers were more common among unaffected family members (Simons) than unrelated controls (TGen), but the statistical significance of this effect was marginal (Chi squared P < 0.09). Conclusions Unlike group difference approaches, our analysis identified the samples within the case and control groups that manifested each expression signal, and showed that outlier groups were distinct for each implicated pathway. Moreover, our results suggest that by seeking heterogeneity, pathway-based outlier analysis can reveal expression signals that are not apparent when considering only shared group differences.

To investigate the distribution features of Chinese medical constitutions in hypertension complicated diabetes patients. Recruited were 251 primary hypertension inpatients at the Department of Neurology and the Department of Cardiology, Mindong Hospital of Ningde City from October 2010 to March 2011. They were assigned to two groups according to whether they were complicated with diabetes, i.e., the primary hypertension complicated diabetes (as the case group, 78 cases) and the primary hypertension without complicated diabetes (as the control group, 173 cases). The constitution types were investigated by questionnaire. The constitution type distribution was compared between the two groups. The data including gender, age, and the distribution of the constitution type were compared between the two groups. The levels of TG, TC, LDL-C, Hb, FPG, and ALB were detected on the 2nd day after admission. The levels of TG, TC, LDL-C, Hb, and ALB were compared be- tween the two groups in patients of yin deficiency constitution, phlegm dampness constitution, and qi deficiency constitution. There was no statistical difference in the hypertension grading, the disease course, and chronic disease complications between the two groups (P > 0.05). The main constitution types were yin deficiency (accounting for 26.0%), phlegm dampness (accounting for 19.1%), and qi deficiency (accounting for 19.1%) in the control group. The main constitution types were yin deficiency (accounting for 32.1%), phlegm dampness (accounting for 30.8%), and qi deficiency (accounting for 17.9%) in the case group. The ratio of phlegm dampness type in the case group was higher than that in the control group with statistical difference (P = 0.041). There was no statistical difference in the constitution distribution in the same gender between the two groups (P > 0.05). There was no statistical difference in the constitution distribution in those younger than 80 years between the two groups (P > 0.05). Compared with those older than 80 years in the control group, the ratio of phlegm dampness was higher, and the ratios of yang deficiency, yin deficiency, qi deficiency, and dampness heat were lower in the case group with statistical difference (P = 0.020). There was no statistical difference in the constitution distribution among different age stages in the case group (P > 0. 05). But there was statistical difference in the constitution distribution among different age stages in the control group (P < 0.05). The yin deficiency and qi deficiency constitutions were dominated in thinner patients of the control group, while yin deficiency constitution was dominated in thinner patients of the case group, showing no statistical difference between the two groups (P > 0.05). There was no statistical difference in the distribution of constitution type in overweight patients between the two groups (P = 0.458). Compared with those of gentle type constitution in the same group, the levels of TC and LDL-C increased in those of phlegm dampness constitution in the two groups (P < 0.05). The level of TC increased in those of qi deficiency constitution in the case group. The level of Hb decreased in those of qi deficiency constitution in the control group (P < 0.05). Compared with those of qi deficiency constitution in the same group, the levels of TC and Hb obviously increased in those of phlegm dampness constitution in the control group (P < 0.05). The level of ALB increased in those of yin deficiency constitution in the case group (P < 0. 05). Compared with the control group, the level of FPG of those of each constitution increased in the case group (P < 0.05) ,.and the level of TC increased in those of qi deficiency constitution (P = 0.007). The main constitution types of hypertension complicated diabetes patients were yin deficiency, phlegm dampness, and qi deficiency. The ratio of phlegm dampness was higher in hypertension complicated diabetes patients than hypertension without complicated diabetes patients. The levels of TC and LDL-C were higher in those of phlegm dampness constitution type. The level of TC was higher in hypertension complicated diabetes patients of qi deficiency constitution.

To compare the differences of curative effects of herpes zoster treated with acupuncture based on syndrome differentiation combined with pricking and cupping and simple pricking and cupping. Eighty-six cases were randomly divided into an observation group (43 cases) and a control group (43 cases). In observation group, acupoints selection based on syndrome differentiation i.e. Quchi (LI 11), Zusanli (ST 36), Sanyinjiao (SP 6), etc. were selected and pricking and cupping at affected parts were applied, and the cases were classified into damp heat in liver and gallbladder, damp retention and spleen deficiency, and qi deficiency and blood stasis. In control group, all the cases were simplely treated with pricking and cupping at affected parts. The treatment was given once a day, and seven days were made one session. The curative effect was evaluated after 2 courses, and the follow-up was carried on after 1 month. The cured and markedly effective rate was 93.0% (40/43) in observation group, superior to that of 67.4% (29/43) in control group (P < 0.01). Postherpetic neuralgia: there was 2.3% (1/43) in observation group, inferior to that of 14.0% (6/43) in control group. Comparison in 3 types: the cured and markedly effective rate of damp heat in liver and gallbladder: 94.7% (18/19) in observation group, and 85.7% (18/21) in control group, showing no significant difference between groups (P > 0.05). The cured and markedly effective rate of damp retention and spleen deficiency: 93.8% (15/16) in observation group, superior to that of 60.0% (9/15) in control group (P < 0. 05). The cured and markedly effective rate of qi deficiency and blood stasis: 87.5% (7/8) in observation group, superior to that of 28.6% (2/7) in control group (P < 0.05). For herpes zoster, acupoints selection based on syndrome differentiation combined with pricking and cupping therapy is high pertinent and effective, the postherpetic neuralgia can be reduced significantly and the curative effect is superior to that of simple pricking and cupping.

To assess the validation of a novel control selection design by comparing the consistency between the new design and a routine design in a large case-control study that was incorporated into a nationwide mortality survey in China. A nationwide mortality study was conducted during 1989-1991. Surviving spouses or other relatives of all adults who died during 1986-1988 provided detailed information about their own as well as the deceased person's smoking history. In this study, 130,079 males who died of various smoking-related cancers at age 35 or over were taken as cases, while 103,248 male surviving spouses (same age range with cases) of women who died during the same period and 49,331 males who died from causes other than those related to smoking were used as control group 1 and control group 2, respectively. Consistency in the results when comparing cases with each of the control groups was assessed. Consistency in the results was observed in the analyses using different control groups although cancer deaths varied with region and age. Equivalence could be ascertained using a 15% criterion in most cancer deaths which had high death rates in urban areas, but they were uncertain for most cancers in rural areas irrespective of whether the hypothesis testing showed significant differences or not. Sex-matched living spouse control design as an alternative control selection for a case-control study is valid and feasible, and the basic principles of the equivalence study are also supported by epidemiological survey data.

To study the influence of high-frequency electric surgical knives on healing of abdominal incision. Two hundred and forty white rats were divided into 10(0), 10(2), 10(5), and 10(8) groups and rat models of abdominal operation were induced by using electric surgical knives and common lancets respectively. Then they were respectively given hypodermic injections of normal saline and 0.2 mL quantitative mixture of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa at a concentration of 10(2), 10(5) and 10(8). On the basis of the animal experiment, 220 patients undergoing abdominal operations (above type II) were randomly allocated into one of following three groups: electric knife (EK, 93 cases), electro-coagulation (EC, 55 cases) and control (72 cases). High-frequency electric surgical knives were used to dissect abdominal tissues and electro-coagulation for hemostasis in EK group. Common lancets and electro-coagulation were applied in EC group. Common lancets and tying silk suture were used in the controls. In all the groups except group 10(0), infection rate of incisional wounds made by electric surgical knives were remarkably higher than that with common lancets. Furthermore, there were significant differences in groups 10(2), 10(5), and 10(8) (P<0.05), but not in group 10(0) (P>0.05) between EK and EC groups. Clinical studies showed a delayed wound healing in 16 cases (17.20%) in EK, 11 cases (16.36%) in EC and 2 cases (2.86%) in the control groups. A significant difference between EK and the control groups (chi2 = 8.57, P<0.01), and between EC and the control groups (chi2 = 5.66, P<0.05) was observed, but not between EK and EC (chi2 = 0.017, P>0.05). High-frequency electric knives may remarkably delay abdominal incision healing. Its application should be minimized so as to reduce the possibility of postoperative complications.

Bartter syndrome is a severe inherited tubulopathy characterized at birth by salt wasting, severe polyuria, dehydration, growth retardation and secondary hyperaldosteronism. Prenatally, the disease is usually discovered following onset of severe polyhydramnios. We studied amniotic fluid aldosterone concentration in cases of Bartter syndrome and in control groups. Amniotic fluid aldosterone was assayed by radioimmunoassay. We undertook a retrospective case-control study based on 36 cases of postnatally diagnosed Bartter syndrome and 144 controls matched for gestational age. Two controls groups were defined: controls with polyhydramnios (n=72) and control without polyhydramnios (n=72). Amniotic fluid aldosterone was compared between the three groups. The median amniotic fluid aldosterone concentration in the Bartter syndrome group (90 pg/mL) did not differ significantly from that in the controls with polyhydramnios (90 pg/mL, p=0.33) or the controls without polyhydramnios (87 pg/mL, p=0.41). In conclusion, amniotic fluid aldosterone assay cannot be used for prenatal diagnosis of Bartter syndrome.

Young adults with Type 2 diabetes have higher physical morbidity and mortality than other diabetes sub-groups, but differences in psychosocial outcomes have not yet been investigated. We sought to compare depression and anxiety symptoms and self-care behaviours of young adults with Type 2 diabetes with two matched control groups. Using cross-sectional survey data from the Australian and Dutch Diabetes Management and Impact for Long-term Empowerment and Success (MILES) studies, we matched 93 young adults (aged 18-39 years) with Type 2 diabetes (case group) with: (i) 93 older adults ( ≥ 40 years) with Type 2 diabetes (Type 2 diabetes control group; matched on country, gender, education, diabetes duration and insulin use) and (ii) 93 young adults with Type 1 diabetes (Type 1 diabetes control group; matched on country, gender, age and education). Groups were compared with regard to depression symptoms (nine-item Patient Health Questionnaire), anxiety symptoms (seven-item Generalised Anxiety Disorder questionnaire) and frequency of selected self-care behaviours (single item per behaviour). Participants in the case group had higher depression scores (Cohen's d = 0.40) and were more likely to have clinically meaningful depressive symptoms (Cramer's V = 0.23) than those in the Type 2 diabetes control group. Participants in the case group had statistically equivalent depression scores to the Type 1 diabetes control group. The groups did not differ in anxiety scores. Those in the case group were less likely than both control groups to take insulin as recommended (Cramer's V = 0.24-0.34), but there were no significant differences between the groups in oral medication-taking. The case group were less likely than the Type 2 diabetes control group to eat healthily (Cramer's V = 0.16), and less likely than the Type 1 diabetes control group to be physically active (Cramer's V = 0.15). Our results suggest that Type 2 diabetes is as challenging as Type 1 diabetes for young adults and more so than for older adults. Young adults with Type 2 diabetes may require more intensive psychological and self-care support than their older counterparts. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

Background The nocturnal enuresis is one of the most common complaints of childhood. Upper airway obstruction and nocturnal snoring affect the nocturnal enuresis in children. Objectives The aim of this study was to investigate the effects of breathing exercises on the nocturnal enuresis in the children with the sleep-disordered breathing. Patients and Methods This study was conducted in year of 2011 by a semi-experimental design with the control group among 40 children, aged 6 - 12 years, who had the nocturnal enuresis. Participants were examined based on the criteria of nocturnal enuresis, oral breathing, and nocturnal snoring. Subsequently, they were randomly assigned to the case and control groups. In the case group, the breathing exercises were performed for 45 minutes, and were pursued for four weeks in the morning following and prior to sleeping, and subsequently the arterial blood gases were measured and the frequency of enuresis and the respiratory rates (RR) were recorded. Results After intervention the means of PaCO2 and RR in the control group were significantly higher than the case group (P < 0.0001). Likewise, O2sat, PaO2 in the case group were higher than the control group (P < 0.0001). The nocturnal enuresis decreased significantly in the case group, compared to the control group (P < 0.0001). Conclusions This study suggests that the breathing exercises may reduce the frequency of nocturnal enuresis in the patients with the oral breathing and nocturnal snore. The clinical implications of these findings should be verified in the future longitudinal studies. PMID:24719691

There are no longitudinal studies that assess the impact of traumatic dental injury (TDI) on the oral health-related quality of life (OHRQoL) of preschool children. To investigate the impact of TDI on OHRQoL among preschool children, a population-based case-control study was carried out with a representative sample of 335 children, 3-5 years of age, enrolled at public and private preschools in the city of Campina Grande, Brazil. The case group and the control group were matched for age, gender, type of preschool and monthly household income at a ratio of 1:4 (67 cases and 286 controls). Impact on the OHRQoL of children was assessed through administration of the Early Childhood Oral Health Impact Scale (ECOHIS). The occurrence of TDI was determined through clinical examinations performed by three calibrated dentists. Data analysis involved descriptive statistics, McNemar's test, the chi-square test with linear trend and conditional logistic regression analysis [P≤0.05; 95% confidence interval (95% CI)]. The most frequent responses were 'felt pain' (19.4%) and 'difficulty eating' (16.4%). The prevalence of TDI was 37.3% in the case group and 33.9% in the control group. No statistically significant differences were found between case and control groups regarding the presence of TDI (odds ratio=1.16; 95% CI: 0.66-2.02). TDI had no impact on the quality of life of preschool children. © 2015 FDI World Dental Federation.

Malaria and HIV/AIDS are two of the most widespread infectious diseases encountered in sub-Saharan Africa. Even minor interactions between these two diseases could have substantial effects on public health. The purpose of this study was to investigate associations between malaria and HIV infection. Study was carried out over an 8-month period (April 1, 2003 to November 30, 2003) in the Tropical and Infectious Diseases Department of the Donka National Hospital in Conakry, Guinea. A total of 89 malaria patients including 41 cases with HIV infection and 48 controls without HIV infection were included. All patients were hospitalized during the study and provided informed consent. Results showed that malaria affected all age groups in the same proportion. Mean patient age was 34 years (range, 15 and 76 years). Males were more frequently infected with a sex ratio of 1.05. The average number of malaria episodes was higher in cases (malaria with HIV-infection than in controls (malaria without HIV infection). Hyperthermia was observed in most cases (68.29%) and controls (77.08%). Severe anemia was observed in 26.82% of cases versus 10.41% of controls. Low parasite density was observed in 73.17% of cases as compared to 68.75% of controls. The recovery rate was higher in the control group than in case group: 27.08% versus 14.63%. The death rate was higher in the case group than in the control group: 21.95% versus 6.25%. These findings demonstrate a link between malaria and HIV. The frequency of malaria episodes was higher in patients with HIV infection than patients without HIV infection and the outcome of malarial episodes was better in patients without HIV infection.

Aluminum phosphide (AlP) is a very effective indoor and outdoor pesticide. We investigated the effects of N-acetyl cysteine (NAC) on the survival time, hemodynamics, and cardiac biochemical parameters at various time intervals in some cases of AlP poisoning. This research was a case-control study to evaluate 63 AlP poisoned patients during 2010-2012. Patients with cardiovascular complications of AlP to be treated with intravenous NAC plus conventional treatment were considered as the case group and compared with patients who did not receive NAC. NAC infusion was administered to the case group at 300 mg/kg for 20 h. The data gathered included age, sex, heart rate, Systolic blood pressure (SBP), creatine phosphokinase (CPK), creatine kinase MB (CK-MB), and ECG at the admission time and 12, 18, and 24 h after admission. Analysis of repeated measures was performed to check the variability of parameters over time. The mean ages in the case and control groups were 26.65 ± 1.06 (19-37 years) and 28.39 ± 1.11 (18-37 years), respectively (P = 0.266). Most of the patients were female (56.5%). CK-MB means were significantly different between the two groups, but no differences between the other variables were observed. Also, CK-MB, CPK, heart rate, and systolic blood pressure means became significantly different over time (0, 12, 18, and 24 h) in both groups (P < 0.001). NAC prevented sharp heart rate fluctuations in AlP patients in the case group. Regarding the outcomes, 17 patients died (10 patients in the control and 7 patients in the case groups). No side-effects of NAC were observed. Our patients could be managed by the positive role of NAC as the biochemical index of cardiotoxicity was found to elevate in both the case and control groups. Therefore, for the management protocol optimization, NAC evaluation should be done in further cases.

During past decades, a connection between hepatitis and the host ABO/Rh blood groups has been always under dispute, with no appropriately designed study yet. This study aimed to investigate possible association between ABO blood/Rh groups with both hepatitis B and C. In this case-control setting, 200 healthy individuals (controls), 200 patients with chronic Hepatitis-B infection (HB) and 200 patients with chronic Hepatitis-C infection (HC) were recruited from 2010 to 2013 in Tabriz Sina Hospital. ABO blood and Rh grouping was performed and the results were compared between the case and control groups. Both pair of the control and HB groups and the control and HC groups were matched for their subjects' age and sex. In the control group, 178 subjects (89%) were Rh+ and 22 subjects (11%) were Rh-. In the HB group, there were 180 Rh+ (90%) and 20 Rh- (10%) patients. In the HC group there were 168 Rh+ (84%) and 32 Rh-negative (16%) patients. Both pair of the control and HB groups (p = 0.74), as well as the control and HC groups (p = 0.14) were comparable for the status of Rh. In the control group there were 84 (42%), 32 (16%), 66 (33%) and 18 (9%) subjects with A, B, O and AB blood groups, respectively. The corresponding figures were 84 (42%), 34 (17%), 58 (29%) and 24 (12%) for the HB patients; and 80 (40%), 29 (14.5%), 85 (42.5%) and 6 (3%) for the HC patients. Comparing between the control and HB groups showed no significant difference in terms of the frequency of ABO blood groups (p = 0.70). However, with comparing the control and HC groups, the rate of O blood group was significantly higher in the HC group and concomitantly, the rate of AB blood group was significantly higher in the control group (p = 0.04). Although, there is not a significant association between ABO blood groups and HB, this association is significant between certain ABO blood groups and HC.

In recent years several reports of influenza vaccine effectiveness (VE) have been made early for public health decision. The majority of these studies use the case test-negative control design (TND), which has been showed to provide, under certain conditions, unbiased estimates of influenza VE. Nevertheless, discussions have been taken on the best influenza negative control group to use. The present study aims to contribute to the knowledge on this field by comparing influenza VE estimates using three test-negative controls: all influenza negative, non-influenza respiratory virus and pan-negative. Incident ILI patients were prospectively selected and swabbed by a sample of general practitioners. Cases were ILI patients tested positive for influenza and controls ILI patients tested negative for influenza. The influenza negative control group was divided into non-influenza virus control group and pan-negative control group. Data were collected on vaccination status and confounding factors. Influenza VE was estimated as one minus the odds ratio of been vaccinated in cases versus controls adjusted for confounding effect by logistic regression. Confounder adjusted influenza VE against medically attended laboratory-confirmed influenza was 68.4% (95% CI: 20.7-87.4%) using all influenza negatives controls, 82.1% (95% CI: 47.6-93.9%) using non-influenza controls and 49.4% (95% CI: -44.7% to 82.3%) using pan-negative controls. Influenza VE estimates differed according to the influenza negative control group used. These results are in accordance with the expected under the hypothesis of differential viral interference between influenza vaccinated and unvaccinated individuals. Given the wide importance of TND study further studies should be conducted in order to clarify the observed differences. Copyright © 2014 Elsevier Ltd. All rights reserved.

To observe clinical effect of nanometer acupoint mounting method for alleviation of myospasm complicated by spinal injury. Sixty cases were randomly divided into an observation group and a control group, 30 cases in each group. The observation group were treated by nanometer mounting at 4 Jiaji (EX-B 2) points each on both sides of the affected spine and Shenshu (BL 23), Shangliao (BL 31), Ciliao (BL 32), Yang-lingquan (GB 34), Xuanzhong (GB 39); and the control group by mounting zinc oxide sticking tablets at the above acupoints. The mounting was replaced once each two days, 7 times constituting one course. One week and one month after the end of 3 courses, their results were recorded, respectively. Before treatment, there was no significant difference between the two groups in grades of the myospasm degree (P > 0.05). One week after the end of treatment, 15 cases were grade I of myospasm, 9 cases were grade II, 5 cases were grade III and 1 case was grade IV in the observation group, and 1 cases grade I, 7 cases grade II, 14 cases grade III, 8 cases grade IV in the control group. Ridit analysis on the data indicated that there were significant differences before and after treatment in the myospasm degree (P < 0.01) and between the two groups after treatment (P < 0.01). One month after the end of treatment, the results were similar to those one week after the end of treatment. Nanometer acupoint mounting method is a new one for alleviation of myospasm complicated by spinal injury, with convenience, safety and no side effect.

To seek for a safe and effective drug to treat hyperthyroidism. Sixty cases of hyperthyroidism with leukocytopenia induced by sulfourea drugs were divided into treatment and control groups by 31 cases who were treated by traditional medicine Syndrome Differentiation and 29 cases who were treated by conventional western medicine alone respectively at random. They were estimated by total effective rate, major symptoms, WBC and immunological tests after four weeks. The total effective rate in the treatment group (96.8%) was more effective than that in the control group (86.2%, P < 0.05). The symptom recovery rate in the treatment group was better than that in the control group. The WBC in both were all increased, but in the treatment group, it was better than that in the control group (P < 0.05). The positive to negative rate of thyroglobulin antibody and thyromicrosome antibody in the treatment group was better than that in the control group (P < 0.01). It can not only improve the symptoms and immune function, but also increase WBC by using western medicine in combination with traditional medicine in treating hyperthyroidism.

Purpose To evaluate the role of argon laser as an adjunctive therapy in ten patients with resistant infected corneal ulcers with or without hypopyon. Methods The study included 20 patients, split into two groups of ten, with resistant infected corneal ulcers with or without hypopyon. One group was considered as the control group and treated with local and systemic specific antimicrobial drugs guided with culture and sensitivity tests. The other group started with the same specific therapy as the control group for 1 week with no obvious improvement and then was further treated with argon laser. The ten patients in the control group included five cases of fungal ulcers, three mixed (fungal and bacterial) ulcers, and two viral ulcers. The ten patients in the other group included three cases of fungal ulcers, three mixed (fungal and viral) ulcers, three viral ulcers, and one bacterial ulcer as proven with microbial culture and sensitivity tests. Eight cases of the control group and seven cases of the other group were associated with hypopyon. Before laser treatment, a drop of benoxinate hydrochloride 0.4% and a single drop of fluorescein sodium 0.25% were instilled. Argon laser irradiation of the affected cornea was performed using an argon 532 nm wavelength (Carl Zeiss LSL 532s AG; Carl Zeiss Meditec AG, Jena, Germany). A spot size of 500 μm, pulse duration of 0.2 seconds, and power of 900 mW were used. All cases were followed up for 3 months after healing was achieved. Results During the first 4 weeks after laser treatment, all patients showed complete healing of the epithelial defect and resolution of stromal infiltration with no adverse effects. In the control group, four cases needed an amniotic membrane graft due to thinning and the other six cases were healed in a duration that ranged from 3 to 7 weeks. Conclusion Argon laser phototherapy is useful as an adjunctive treatment for resistant infected corneal ulcers. More cases are needed to get more reliable results and to confirm our findings.

The ten patients in the control group included five cases of fungal ulcers, three mixed (fungal and bacterial) ulcers, and two viral ulcers. The ten patients in the other group included three cases of fungal ulcers, three mixed (fungal and viral) ulcers, three viral ulcers, and one bacterial ulcer as proven with microbial culture and sensitivity tests. Eight cases of the control group and seven cases of the other group were associated with hypopyon. Before laser treatment, a drop of benoxinate hydrochloride 0.4% and a single drop of fluorescein sodium 0.25% were instilled. Argon laser irradiation of the affected cornea was performed using an argon 532 nm wavelength (Carl Zeiss LSL 532s AG; Carl Zeiss Meditec AG, Jena, Germany). A spot size of 500 μm, pulse duration of 0.2 seconds, and power of 900 mW were used. All cases were followed up for 3 months after healing was achieved. During the first 4 weeks after laser treatment, all patients showed complete healing of the epithelial defect and resolution of stromal infiltration with no adverse effects. In the control group, four cases needed an amniotic membrane graft due to thinning and the other six cases were healed in a duration that ranged from 3 to 7 weeks. Argon laser phototherapy is useful as an adjunctive treatment for resistant infected corneal ulcers. More cases are needed to get more reliable results and to confirm our findings.

Background Whether the presence of type 2 diabetes mellitus (T2DM) increases the risk of hepatocellular carcinoma (HCC) in hepatitis B virus (HBV) cirrhosis patients is controversial. We conducted a retrospective case-control study to evaluate this issue. Material/Methods We considered all patients diagnosed with HBV-related liver cirrhosis at our hospital from July 2011 to June 2014. The case (n=91) and control (n=91) groups were HBV cirrhosis patients with and without T2DM, respectively. They were matched at a ratio of 1: 1 according to the individual age (±2 years) and same sex and Child-Pugh score. Results None of the baseline data were significantly different between the 2 groups. The percentage of HCC was similar between the 2 groups (case versus control group: 34.1% versus 46.2%, P=0.13). In the case group, sex (P=0.002), alkaline phosphatase (P<0.001), γ-glutamine transferase (P=0.001), and sodium (P=0.003) were associated with the risk of HCC. In the control group, platelet (P=0.041), alanine aminotransferase (P=0.034), aspartate aminotransferase (P=0.026), alkaline phosphatase (P<0.001), and γ-glutamine transferase (P<0.001) were associated with the risk of HCC. Conclusions T2DM may not be a risk factor for the presence of HCC in HBV cirrhosis. PMID:28689209

Objectives Perinatal asphyxia (PA) is very significant in perinatal medicine due to the involvement of the central nervous system. This study was conducted to investigate the biochemical, clinical, and paraclinical changes associated with phenobarbital administration in neonates with PA. Methods In this prospective, case-control study, 30 neonates with PA in two groups of 15 each (case and control) were investigated. The case group received 20 mg/kg intravenous phenobarbital within six hours of birth, and the control group did not receive phenobarbital. Serum concentrations of nitric oxide (NO) were measured at enrollment and one week after birth in the two groups. Clinical, electroencephalography, and magnetic resonance imaging findings of the two groups were compared. Results At enrollment, the two groups did not differ in clinical severity, seizure incidence, or NO concentration. After one week, NO concentration was significantly lower in the case group (p < 0.050), but there was no significant difference in other variables between the two groups. Conclusions Early administration of phenobarbital in term neonates with PA could protect them against encephalopathy. PMID:27602186

To investigate the effect of axial stress stimulation on tibial and fibular open fractures healing after Taylor space stent fixation. The data of 45 cases with tibial and fibular open fractures treated by Taylor space stent fixation who meet the selection criteria between January 2015 and June 2016 were retrospectively analysed. The patients were divided into trial group (23 cases) and control group (22 cases) according to whether the axial stress stimulation was performed after operation. There was no significant difference in gender, age, affected side, cause of injury, type of fracture, and interval time from injury to operation between 2 groups ( P >0.05). The axial stress stimulation was performed in trial group after operation. The axial load sharing ratio was tested, and when the value was less than 10%, the external fixator was removed. The fracture healing time, full weight-bearing time, and external fixator removal time were recorded and compared. After 6 months of external fixator removal, the function of the limb was assessed by Johner-Wruhs criteria for evaluation of final effectiveness of treatment of tibial shaft fractures. There were 2 and 3 cases of needle foreign body reaction in trial group and control group, respectively, and healed after symptomatic anti allergic treatment. All the patients were followed up 8-12 months with an average of 10 months. All the fractures reached clinical healing, no complication such as delayed union, nonunion, or osteomyelitis occurred. The fracture healing time, full weight-bearing time, and external fixator removal time in trial group were significantly shorter than those in control group ( P <0.05). After 6 months of external fixator removal, the function of the limb was excellent in 13 cases, good in 6 cases, fair in 3 cases, and poor in 1 case in trial group, with an excellent and good rate of 82.6%; and was excellent in 5 cases, good in 10 cases, fair in 4 cases, and poor in 3 cases in control group, with an excellent and good rate of 68.2%, showing significant difference between 2 groups ( Z =-2.146, P =0.032). The axial stress stimulation of Taylor space stent fixation can promote the healing of tibial and fibular open fractures and promote local bone formation at fracture site.

By means of a mailed questionnaire, the investigators examined the incidence of cancer among 2282 former college students in whom heterophile-positive infectious mononucleosis (IM) was diagnosed between 1949 and 1969 at five U.S. universities. Cancer incidence among these IM cases was compared both with national incidence rates and with an age and sex-matched group of 2779 non-IM students. No significant increase in cancer incidence was found. Three cases of Hodgkin's disease (HD) had occurred in the IM group (1.3 cases expected) and one case in the control group. All three post-IM cases of HD were in males. Intervals between diagnoses of IM and HD were three, four, and seven years, respectively. Only two other cases of lymphoma or leukemia were observed, and both were in the control group.

To analyze the compliance of sublingual desensitization used in allergic rhinitis patients by telephone follow up, and to discuss the influencing factor associate with medicine pause. One hundred and thirty-two patients of allergic rhinitis were randomly divided into two groups, 53 cases was in the control group, 79 cases was in telephone follow up group for a period of 6 months of observation. Sublingual desensitization treatment for 6 months, 28/53 cases of control group were compliance, 25/53 cases were loss, and compliance rate was 52.8%; 17/27 cases of follow-up group A were compliance, 10/27 cases were loss, and compliance rate was 63.0%; 21/28 cases of follow-up group B were compliance, 7/28 cases were loss, and compliance rate was 75.0%; 22/24 of follow-up group C were compliance, 2/24 cases were loss, and compliance rate was 91.7% (P < 0.05). Significant difference was found in the 4th month after treatment (P < 0.01). Long-term treatment and cure were the main impact factors for compliance. Timely telephone follow-up education and guidance to patients could improve compliance of patients with sublingual desensitization.

Case management has been shown to be beneficial in phases of cancer screening and treatment. After treatment is completed, patients experience a loss of support due to reduced contact with medical professionals. Case management has the potential to offer continuity of care and ease re-entry to normal life. We therefore aim to investigate the effect of case management on quality of life in early cancer survivors. Between 06/2010 and 07/2012, we randomized 95 patients who had just completed cancer treatment in 11 cancer centres in the canton of Zurich, Switzerland. Patients in the case management group met with a case manager at least three times over 12 months. Patient-reported outcomes were assessed after 3, 6 and 12 months using the Functional Assessment of Cancer Therapy (FACT-G) scale, the Patient Assessment of Chronic Illness Care (PACIC) and the Self-Efficacy scale. The change in FACT-G over 12 months was significantly greater in the case management group than in the control group (16.2 (SE 2.0) vs. 9.2 (SE 1.5) points, P = 0.006). The PACIC score increased by 0.20 (SE 0.14) in the case management group and decreased by 0.29 (SE 0.12) points in the control group (P = 0.009). Self-Efficacy increased by 3.1 points (SE 0.9) in the case management group and by 0.7 (SE 0.8) points in the control group (P = 0.049). Case management has the potential to improve quality of life, to ease re-entry to normal life and to address needs for continuity of care in early cancer survivors. The study has been submitted to the ISRCTN register under the name "Case Management in Oncology Rehabilitation" on the 12th of October 2010 and retrospectively registered under the number ISRCTN41474586 on the 24th of November 2010.

Ulnar styloid fractures are often associated with distal radius fractures. However, controversy exists regarding whether to treat ulnar styloid fractures. This study aimed to evaluate clinical effects of internal fixation for ulnar styloid fractures after distal radius fractures were treated with the volar locking plate system. We used prospectively collected data of distal radius fractures. 111 patients were enrolled in this study. A matched case-control study design was used. We selected patients who underwent fixation for ulnar styloid fractures (case group). Three control patients for each patient of the case group were matched on the basis of age, sex, and fracture type of distal radius fractures from among patients who did not undergo fixation for ulnar styloid fractures (control group). The case group included 16 patients (7 men, 9 women; mean age: 52.6 years; classification of ulnar styloid fractures: center, 3; base, 11; and proximal, 2). The control group included 48 patients (15 men, 33 women; mean age: 61.1 years; classification of ulnar styloid fractures: center, 10; base, 31; and proximal, 7). For radiographic examination, the volar tilt angle, radial inclination angle, and ulnar variance length were measured, and the union of ulnar styloid fractures was judged. For clinical examination, the range of motions, grip strength, Hand20 score, and Numeric Rating Scale score were evaluated. There was little correction loss for each radiological parameter of fracture reduction, and these parameters were not significantly different between the groups. The bone-healing rate of ulnar styloid fractures was significantly higher in the case group than in the control group, but the clinical results were not significantly different. We revealed that there was no need to fix ulnar styloid fractures when distal radius fractures were treated via open reduction and internal fixation with a volar locking plate system.

Perforation peritonitis continues to be one of the most common surgical emergencies that need a surgical intervention most of the times. Anesthesiologists are invariably involved in managing such cases efficiently in perioperative period. The assessment and evaluation of Acute Physiology and Chronic Health Evaluation II (APACHE II) score at presentation and 24 h after goal-directed optimization, administration of empirical broad-spectrum antibiotics, and definitive source control postoperatively. Outcome assessment in terms of duration of hospital stay and mortality in with or without optimization was also measured. It is a prospective, randomized, double-blind controlled study in hospital setting. One hundred and one patients aged ≥18 years, of the American Society of Anesthesiologists physical Status I and II (E) with clinical diagnosis of perforation peritonitis posted for surgery were enrolled. Enrolled patients were randomly divided into two groups. Group A is optimized by goal-directed optimization protocol in the preoperative holding room by anesthesiology residents whereas in Group S, managed by surgery residents in the surgical wards without any fixed algorithm. The assessment of APACHE II score was done as a first step on admission and 24 h postoperatively. Duration of hospital stay and mortality in both the groups were also measured and compared. Categorical data are presented as frequency counts (percent) and compared using the Chi-square or Fisher's exact test. The statistical significance for categorical variables was determined by Chi-square analysis. For continuous variables, a two-sample t -test was applied. The mean APACHE II score on admission in case and control groups was comparable. Significant lowering of serial scores in case group was observed as compared to control group ( P = 0.02). There was a significant lowering of mean duration of hospital stay seen in case group (9.8 ± 1.7 days) as compared to control group ( P = 0.007). Furthermore, a significant decline in death rate was noted in case group as compared to control group ( P = 0.03). Goal-directed optimized patients with perforation peritonitis were discharged early as compared to control group with significantly lesser mortality as compared with randomly optimized patients in the perioperative period.

Background: Coronary Artery Disease is known as the main cause of death in industrialized countries. Relation between this disease and some infections such as Helicobacter pylori (H.pylori) has been shown in several studies. The purpose of this study was to dermine the relationship between Hypylori and mycardical infarctions. Methods: Seventy-three myocardial infarction patients and 78 individuals with no history of this disease were compared. Patients and control matched for age and sex person to person by the match method. Levels of serum IgA and IgG antibodies against H. pylori were measured by Elisa method. Also, cholesterol, triglyceride, LDL, HDL measured in both groups and data were compared between two groups in terms of relation with cardiac risk factors. Results: From 151 participants, 73 were patients and 78 were control subjects. The percentage of IgG positive cases against H. pylori was 57.5% in the case group and 32.1% in the control group (p=0.002, OR: 2.87 CI: 95%; 1.5-5.6). Meanwhile, there was no significant difference in IgA positive cases between the two groups (42.5% and 48.7% in the case and control groups, respectively) (p=0.44; OR: 0.78 95% CI; 0.41-1.48). The study showed 74.2% of cases in the case group and 45.2% in the control group were positive for both IgG and IgA (p=0.01; OR: 3.5 95% CI; 1.3-9.5). No significant differences were found between two groups in terms of relation between H. pylori related antibodies level and heart disease classic risk factors (smoking, hypertension,…), sex, and age, but between dyslipidemia and H. pylori related antibodies was significant differences in case group (p=0.05). Conclusion: According to the results, it seems there is a relation between H. pylori infection and myocardial infarction. Also, between dislipidemia and H. Pylori antibodies in case group were significant difference. Therefore, H. pylori can be a new risk factor for atherosclerosis or can be exacerbate effect of other risk factors. Proper diagnosis and treatment of these infections can be useful in prone patients. More studies with larger sample groups are needed to review the possible role of this pathogen as a heart disease risk factor. PMID:24024020

AIM To evaluate the effect of nonsurgical periodontal therapy on glycosylated haemoglobin levels in pre-diabetic patients with chronic periodontitis (CHP). METHODS Sixty pre-diabetic patients with CHP were selected and equally allocated to case and control group. All subjects were evaluated at base line for periodontal parameters (plaque index, oral hygiene index, modified gingival index, probing pocket depth, clinical attachment level) and systemic parameters [glycosylated hemoglobin (HbA1c), fasting lipid profile, and fasting blood glucose]. The case group received non-surgical periodontal therapy. Subjects were re-evaluated for periodontal and systemic parameters after three months. RESULTS Both groups were comparable at baseline. Three months after non surgical periodontal therapy (NSPT), there was significant improvement in periodontal parameters in case group. The mean difference in systemic parameters like HbA1c and fasting plasma glucose from baseline to fourth month for case group was 0.22 ± 0.11 and 3.90 ± 8.48 respectively and control group was -0.056 ± 0.10 and -1.66 ± 6.04 respectively, which was significant between case and control group (P < 0.05). In the case group there was a significant decrease in HbA1c from baseline to three months following NSPT (P < 0.05). CONCLUSION This study showed that periodontal inflammation could affect the glycemic control in otherwise systemically healthy individuals. Periodontal therapy improved periodontal health status and decreased glycosylated haemoglobin levels, thus reducing the probability of occurrence of inflammation induced prediabetes in patients with CHP.

We aimed to assess the effects of electronic nicotine delivery system (ENDS) or also termed electronic cigarette vapor on the laryngeal mucosa of rats. Sixteen female Wistar albino rats were divided into two groups. The study group was exposed to ENDS vapor for 1 hour/day for 4 weeks. The control group was not subjected to any chemical or physical stimulus. The vocal folds of the study and control group rats were evaluated histopathologically by hematoxylin and eosin staining and immunohistochemically by Ki67 staining. Epithelial distribution, inflammation, hyperplasia, and metaplasia were evaluated. Epithelial distribution and inflammation did not differ between the two groups. Two cases of hyperplasia were detected in the study group but there was no hyperplasia in the control group. Four cases of metaplasia were detected in the study group and one case in the control group. Statistical analysis revealed no significant difference between the study and control groups (P = 0.131 and 0.106, respectively). Exposure to ENDS for 4 weeks caused hyperplasia and metaplasia of the laryngeal mucosa of rats but this was not significant statistically. These results implemented that further studies with larger cohort and longer duration are required to evaluate long-term effects. Copyright © 2015 The Voice Foundation. Published by Elsevier Inc.

The aim of this study was to explore the inter-relationship between polycystic ovary syndrome and gestational diabetes mellitus, and demonstrate maternal and fetal outcomes. This was a case-control study in 1360 pregnant women who received a diagnosis of gestational diabetes mellitus between 24 and 28 weeks of gestational age. Among all diagnosed with gestational diabetes mellitus, 150 pregnant women had received a polycystic ovary syndrome, and 160 women who did not have polycystic ovary syndrome were designated as controls. The incidence of pregnancy-induced hypertension was 26.3% and 12% in the case and control groups, respectively. Preeclampsia was seen at an incidence of 12% and 6% in case and in control groups, respectively. The difference in neonatal hypoglycemia between the two groups was statistically significant, with an incidence of 17% and 5% in the case and in control groups, respectively. This study demonstrated that the presence of polycystic ovary syndrome along with gestational diabetes mellitus increases the risk of pregnancy induced hypertension by 2.4 fold, preeclampsia by 2 fold and neonatal hypoglycemia by 3.2 fold, compared to gestational diabetes mellitus alone.

Existing single-case studies have reported deficit in recognizing basic emotions through facial expression and unaffected performance with body expressions, but not the opposite pattern. The aim of this paper is to present a case study with impaired emotion recognition through body expressions and intact performance with facial expressions. In this single-case study we assessed a 30-year-old patient with autism spectrum disorder, without intellectual disability, and a healthy control group (n = 30) with four tasks of basic and complex emotion recognition through face and body movements, and two non-emotional control tasks. To analyze the dissociation between facial and body expressions, we used Crawford and Garthwaite's operational criteria, and we compared the patient and the control group performance with a modified one-tailed t-test designed specifically for single-case studies. There were no statistically significant differences between the patient's and the control group's performances on the non-emotional body movement task or the facial perception task. For both kinds of emotions (basic and complex) when the patient's performance was compared to the control group's, statistically significant differences were only observed for the recognition of body expressions. There were no significant differences between the patient's and the control group's correct answers for emotional facial stimuli. Our results showed a profile of impaired emotion recognition through body expressions and intact performance with facial expressions. This is the first case study that describes the existence of this kind of dissociation pattern between facial and body expressions of basic and complex emotions.

Methamphetamine, a highly addictive psychostimulant drug, is widely used by substance users who are not motivated to undergo treatment throughout the world, including Iran. This research was conducted to evaluate the effectiveness of a brief home-based social work motivational intervention (HSWMI) to encourage male methamphetamine users to participate in a treatment program. Fifty-six unmotivated male methamphetamine users participated in a randomized controlled trial. The case group received the HSWMI in addition to the usual consulting services in the clinic; the control group just received the usual consulting services. Data were collected 7 and 90 days after the intervention to evaluate participation and retention in a treatment program. Data were analyzed using the chi-square test. Drug users with a mean age of 32.55 years and mean duration of drug use of 7.73 years, participated in the case (n = 28) and control (n = 28) groups. The case group participated in treatment programs significantly more than the control group and the retention rate for the case group was significantly higher than for the control group. This brief HSWMI was effective to increase the motivation of methamphetamine users to participate and remain in treatment programs. This intervention can be implemented by social workers in substance use treatment centers.

To observe the effect of warming needle combined with rehabilitation training on chondromalacia patellae in a randomized controlled trial. The 92 cases were randomly divided into a treatment group treated by warming needle plus rehabilitation training (47 cases) and a control group treated by medication plus rehabilitation training (45 cases), and the therapeutic effect was compared after 20 sessions. The pain was relieved more obviously in the treatment group than in the control group (P < 0.05), and the total effective rate was 91.8% and 71.1% respectively (P < 0.01). Warming needle plus rehabilitation training was superior in the therapeutic effect and duration of producing relief of pain to medication plus rehabilitation training in treating chondromalacia patellae.

In Ireland, pregnant women are not routinely screened for subclinical hypothyroidism (SCH). Our objective was to compare the intelligence quotient (IQ) of children whose mothers had been diagnosed with SCH prenatally with matched controls using a case-control retrospective study. In a previous study from our group, 1000 healthy nulliparous women were screened anonymously for SCH. This was a laboratory diagnosis involving elevated TSH with normal fT4 or normal TSH with hypothyroxinaemia. We identified 23 cases who agreed to participate. These were matched with 47 controls. All children underwent neurodevelopmental assessment at age 7-8. Wechsler Intelligence Scale for Children IV assessment scores were used to compare the groups. Our main outcome measure was to identify whether there was a difference in IQ between the groups. From the cohort of cases, 23 mothers agreed to the assessment of their children as well as 47 controls. The children in the control group had higher mean scores than those in the case group across Verbal Comprehension Intelligence, Perceptual Reasoning Intelligence, Working Memory Intelligence, Processing Speed Intelligence and Full Scale IQ. Mann-Whitney U-test confirmed a significant difference in IQ between the cases (composite score 103.87) and the controls (composite score 109.11) with a 95% confidence interval (0.144, 10.330). Our results highlight significant differences in IQ of children of mothers who had unrecognised SCH during pregnancy. While our study size and design prevents us from making statements on causation, our data suggest significant potential public health implications for routine prenatal screening. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

We investigated the clinical value of alprostadil combined with the α-lipoic acid in treating type 2 diabetes mellitus with erectile dysfunction (DMED). We selected a total of 76 cases of patients who were admitted to endocrinology department of our hospital from June 2014 to June 2015 and diagnosed as DMED, and the average age was (46.7 ± 7.2) years old, average course of diabetes mellitus was (6.2 ± 2.8) years and average body mass index was (25.4 ± 1.3) kg/m2. 40 cases were randomly divided in the observation group while 36 cases were divided in the control group. They received blood glucose control therapy. The patients in the observation group received 60 mg alprostadil hydrochloride and 600 mg α-lipoic acid added into 250 mL normal saline, intravenous drip once per day for 2 weeks. The patients in the control group took tadalafil 5 mg orally, once per night for 2 weeks as a course of treatment. There were no cases of loss. The effective rate of treatment in observation group is significantly higher than that in the control group (95.0% vs. 80.5%, p < 0.05). The score of IIEF-5, EHGS and the FMD value of brachial artery of the observation group after the operation were significantly higher than that of the control group (p < 0.05). The adverse reaction rate in the observation group was lower than that in the control group (7.5% vs. 13.9%, p < 0.05). Alprostadil combined with α-lipoic acid can improve DMED patients' vascular endothelial function and erection hardness to treat erectile dysfunction with less adverse effects and better safety.

To determine the predicative significance of HRV and HRT to premature beat on patients with coal-worker's pneumoconiosis. 100 coal-worker's pneumoconiosis patients with premature beat (including 44 cases of occasional ventricular premature contraction and 56 cases of frequent ventricular premature contraction) were chosen as CWP group, and 50 healthy coal workers were chosen as control group. 24 h DCG was used to monitor and analyze the change of premature beat and to calculate HRV. Index: SDNN, SDANN, HFLF, HRT: TO, TS, compare HRV of CWP group and control group and the changes of HRT of both occasional and frequent ventricular premature contraction. The incidence of CWP at night (66.1%, 37 cases) is higher than that during daytime (33.9%, 19 cases), and the difference is statistically significant with P < 0.05. HRV (SDNN SDANN HF HL) indexes of CWP group are lower than control group, and the difference is statistically significant with P < 0.05. HRV indexes of control group at night are higher than that during daytime, and the difference is statistically significant with P < 0.05. Comparison of CWP group HRV indexes between day and night is statistically insignificant with P > 0.05. Compared with control group, TO of CWP group is higher while TS is lower, and the difference is statistically significant with P < 0.05. Compared with occasional ventricular premature contraction patients in CWP group, TO of frequent ventricular premature contraction patients is higher while TS is lower, and the difference is statistically significant with P < 0.05. Frequent ventricular premature contraction group in CWP group suffer from severe impaired autonomic nervous function injury, and abnormal HRV and HRT can be prognostic indicator of frequent ventricular premature contraction among coal-worker's pneumoconiosis patients.

Constipation is a frequent complication in paediatrics. Most of the constipation is functional. Functional constipation constitutes 25% of visits in paediatric gastroenterology clinics. Two studies were published regarding aggregation or clustering of functional constipation. Only one of these research projects was about a paediatric population. To elucidate the cluster pattern of constipation among the families of children with constipation. This case-control study was carried out on the families of 37 children < 18 years old with chronic functional constipation and the families of 37 healthy children as controls. Cases were enrolled in the study according to Rome III criteria for constipation. The control group was selected from children < 18 years old who visited the well baby clinic of the university. Parents and siblings were evaluated regarding constipation. Rome II and III were used for evaluation of constipation for adults and children, respectively. Data was analysed using SPSS (Chicago, IL, USA). The χ(2) and t-test were used for comparison. Physical activity and vegetable consumption were seen more frequently in the control group compared to the cases, but these differences were statistically insignificant. Constipation in mothers was significantly higher in the case group compared to the control group (p = 0.015). There was no significant difference between the two groups regarding exercise and vegetable consumption. The frequency of constipation among mothers was significantly higher in the case group compared to the control group. Another study is recommended in a larger population for evaluation of genetic background, diet, physical activity, and familial clustering among mothers of children with constipation.

To evaluate the microbiological characteristics of eyelid margin flora in chronic blepharitis in mustard gas-exposed individuals and compare the results with those in age- and sex-matched unexposed people. In this comparative case series, 289 patients with ocular manifestations of mustard gas exposure (case) were evaluated for signs of chronic blepharitis. Additionally, microbiological evaluation of eyelid margins was conducted in these patients and compared with results of 100 unexposed patients with chronic blepharitis (control). One-hundred fifty (52.0%) of 289 mustard gas casualties had signs of chronic blepharitis. Microbiological evaluation revealed higher isolation rates of Staphylococcus epidermidis (78%) and Staphylococcus aureus (57%) in the case in comparison to control group (P < 0.01). Moreover, S. aureus isolated from the cases exhibited greater resistance to common antibiotics compared with control group. Fungi were isolated more frequent in the case compared with controls (30% vs. 4%, P < 0.01), with Cladosporium and Candida species being most common in the case group. Exposure to mustard gas seems to alter the microbiological flora of the eyelid margin. Staphylococcus spp., including antibiotic-resistant strains, and fungi were more frequently isolated in these patients. The relationship between microbial culture results and the severity of ocular surface manifestations in mustard gas-injured cases warrant further investigation.

There is a need to provide more efficient surgical training methods for orthopaedic residents. E-learning could possibly increase resident surgical preparedness, confidence, and comfort for surgery. Using closed reduction and pinning of pediatric supracondylar humeral fractures as the index case, we hypothesized that e-learning could increase resident knowledge acquisition for case preparation in the operating room. An e-learning surgical training module was created on the Computer Enhanced Visual Learning platform. The module provides a detailed and focused road map of the procedure utilizing a multimedia format. A multisite prospective randomized controlled study design compared residents who used a textbook for case preparation (control group) with residents who used the same textbook plus completed the e-learning module (test group). All subjects completed a sixty-question test on the theory and methods of the case. After completion of the test, the control group then completed the module as well. All subjects were surveyed on their opinion regarding the effectiveness of the module after performing an actual surgical case. Twenty-eight subjects with no previous experience in this surgery were enrolled at four academic centers. Subjects were randomized into two equal groups. The test group scored significantly better (p < 0.001) and demonstrated competence on the test compared with the control group; the mean correct test score (and standard deviation) was 90.9% ± 6.8% for the test group and 73.5% ± 6.4% for the control group. All residents surveyed (n = 27) agreed that the module is a useful supplement to traditional methods for case preparation and twenty-two of twenty-seven residents agreed that it reduced their anxiety during the case and improved their attention to surgical detail. E-learning using the Computer Enhanced Visual Learning platform significantly improved preparedness, confidence, and comfort with percutaneous closed reduction and pinning of a pediatric supracondylar humeral fracture. We believe that adapting such methods into residency training programs will improve efficiency in surgical training.

The aim of the present study was to examine the clinical value of ‘tying, binding and fixing operation’ in treating severe mixed hemorrhoids. A total of 160 patients with severe mixed hemorrhoids were selected and randomly divided into the experimental (n=80) and control (n=80) groups. The groups were treated using ‘tying, binding and fixing operation’ and Doppler ultrasound-guided hemorrhoidal artery ligation (DG-HAL), respectively. The results showed that the average operative time of the experimental group (35.57±6.17) was significantly higher than that of the control group (12.73±4.92). There was no significant difference of blood loss during the operation between the two groups (P>0.05). There was also no significant difference in improving the hemorrhage symptom between the two groups (P>0.05). In addition, concerning improvement of prolapse symptoms and reduction of the volume of hemorrhoids, the experimental group were significantly improved as compared to the control group. No anal function damage in the two groups was identified, and the length of stay in hospital for the two groups was not significantly different (P>0.05). However, the hospitalization cost in the experimental group (5,334.77±875.54) was significantly lower than that of the control group (8,551.81±1,806.54) and satisfaction degree was significantly higher than that of the control group. The incidences of perianal pain, anal edema and dysuria between two groups were not significantly different (P>0.05). There were 10 cases of secondary hemorrhage and 18 cases of infection in the experimental group, and 12 cases of secondary hemorrhage and 14 cases of infection in the control group, although the differences between the two groups were not statistically significant (P>0.05). The incidence rate of local hematoma in the experimental group (1.2%) was significantly lower than that in the control group (15.0%). The recurrence rate of the control group (22.5%) was also significantly higher than that of the experimental group (2.5%). In conclusion, tying, binding and fixing operation is a promising method that may be employed for the treatment of sever mixed hemorrhoids, and it is better than DG-HAL in improving the prolapse and reducing the volume of hemorrhoids.

Nursing project management is widely used in different aspects of the society. However, whether the nursing project management can control the infections in the operation room (OR) is rarely reported. We evaluated the outcomes of surgical patients after implementing a nursing project management program to provide new scientific ways to manage the OR infections. Overall, 382 patients, who underwent surgical treatment in Qilu Hospital of Shandong University, Shandong, China from May 2015 to January 2016, were enrolled as observation group. Besides, 347 cases were selected as control group. Patients in the observation group were treated with the nursing project management plan, while patients in the control group were treated with the routine operation-room nursing measures. The infection control rates in the OR, and the patient satisfaction with the nursing team postoperatively were both compared between the two groups of patients. The OR air, the surgical and personnel's hands surfaces were sampled for colony forming units, and all were found to be significantly of better quality (indicated by less colony forming units) in the observation group (P<0.001). In addition, there were 3 cases (0.79%) of post-operation infections in the observation group, while 12 cases (3.46%) occurred in the control group. The overall infection rate of the observation group was significantly lower than that of the control group (P = 0.011); and the satisfaction of patients with the nursing team in the observation group was significantly higher than that of the patients in the control group ( P = 0.001). It is worth popularizing and applying a good nursing project management plan for surgical patients in hospitals.

The present case-control study explored the interaction between marine-derived n-3 long chain polyunsaturated fatty acids (n-3 LC PUFAs) and uric acid (UA) on glucose metabolism and risk of type 2 diabetes mellitus (T2DM). Two hundred and eleven healthy subjects in control group and 268 T2DM subjects in case group were included. Plasma phospholipid (PL) fatty acids and biochemical parameters were detected by standard methods. Plasma PL C22:6n-3 was significantly lower in case group than in control group, and was negatively correlated with fasting glucose (r = -0.177, p < 0.001). Higher plasma PL C22:6n-3 was associated with lower risk of T2DM, and the OR was 0.32 (95% confidence interval (CI), 0.12 to 0.80; p = 0.016) for per unit increase of C22:6n-3. UA was significantly lower in case group than in control group. UA was positively correlated with fasting glucose in healthy subjects, but this correlation became negative in T2DM subjects. A significant interaction was observed between C22:6n-3 and UA on fasting glucose (p for interaction = 0.005): the lowering effect of C22:6n-3 was only significant in subjects with a lower level of UA. In conclusion, C22:6n-3 interacts with UA to modulate glucose metabolism.

Objectives To date, the relationship between C-reactive protein (CRP) level and diabetic retinopathy (DR) remains controversial. Therefore, a systematic review and meta-analysis was used to reveal the potential relationship between CRP level and DR. Methods A systematic search of PubMed, Embase.com, and Web of Science was performed to identify all comparative studies that compared the CRP level of two groups (case group and control group). We defined that diabetic patients without retinopathy and /or matched healthy persons constituted the control group, and patients with DR were the case group. Results Two cross sectional studies and twenty case control studies including a total of 3679 participants were identified. After pooling the data from all 22 studies, obvious heterogeneity existed between the studies, so a subgroup analysis and sensitivity analysis were performed. Removing the sensitivity studies, the blood CRP levels in the case group were observed to be higher than those in the control group [SMD = 0.22, 95% confidence interval (CI), 0.11–0.34], and the blood CRP levels in the proliferative diabetic retinopathy (PDR) group were also higher than those in the non-proliferative diabetic retinopathy (NPDR) group [SMD = 0.50, 95% CI, 0.30–0.70]. Conclusions The results from this current meta-analysis indicate that the CRP level might be used as a biomarker to determine the severity of DR. PMID:26636823

Periodontitis is a chronic infectious disease that leads to inflammation of the tissues supporting the teeth, bone loss, attachment loss progressively. In chronic periodontitis for starting the host response and inflammatory reaction, the presence of the infectious agent is necessary. One of inflammatory factors is tumor necrosis factor-alpha (TNF-α) that appear to be important in the destruction of periodontal tissues that were examined in this study. This study was performed in the laboratory and case-control study. The samples of study collected from 30 individuals with chronic periodontitis and 30 healthy controls that matched for age and sex, together. Unstimulated saliva samples were collected from patients and then TNF-α level were measured by enzyme-linked immunosorbent assay and were compared with the control group. In this study for statistical analysis, Mann-Whitney was used. There were differences in mean salivary concentrations of TNF-α in controls and patients. The average concentration in the case group was 9.1 (pg/ml) and the control group was 8.7 (pg/ml), but there was no significant difference between case and control groups (P > 0.05). The results of this analysis showed no significant relationship between two groups TNF-α concentration. This biomarker can not seem to be a good index to evaluate or predict periodontal disease.

To evaluate the safety and efficacy of sheath (JQL sheath) in the treatment of bladder calculi. We used the novel sheath that we have invented. The water sealing cap can only be passed through the ureteroscope without water leakage, and the diameters of the side hole and the sheath are sufficiently large. The clinical data of the 2 groups of patients include 45 cases of the novel sheath group and 41 cases in the control group. The overall success rate of the 2 groups was 94.79%. The success rate of the new stone sheath group was 97.78% and that of the control group was 90.24%. The operation times were 25.8 ± 12.5 and 46.6 ± 26.3 minutes for the new stone sheath and control groups, respectively. The stones were divided into 3 groups according to their sizes: less than 1.5, 1.5-2.5, and greater than 2.5 cm. The durations of the novel sheath groups were 12.5 ± 6.5, 24.5 ± 9.5, and 37.5 ± 11.5 minutes, whereas those of the control groups were 17.6 ± 6.5, 39.5 ± 18.5, and 49.5 ± 20.5 minutes. Five patients with unsuccessful endovascular treatment were treated with open surgery. Among the 5 cases, 1 case belongs to the novel sheath group and 4 cases to the control group. The novel sheath, whose production is simple and low cost, improves the efficiency of transurethral treatment of bladder calculi and shortens the operation time; furthermore, it involves skills that can be easily mastered and presents clinical application value.

Paget's disease of bone (PDB) may lead to hearing loss. The present study was conducted with the aim of measuring, characterizing and determining the risk factors for hearing loss in a group of subjects with PDB. An observational, transversal, case-control study was conducted, a cohort of 76 subjects diagnosed with PDB in the case group and a control group of 134 subjects were included. Clinical, demographic and audiometric data were analysed. The comparative analysis between the subjects in the PDB group and the control group found that the case group showed higher hearing thresholds (39,51dB) compared with the control group (37.28dB) (P=.069) and presented a greater rate of conductive hearing loss (22.76%) than the control group (12.05%) (P=.0062). The study of risk factors for hearing loss found that skull involvement in bone scintigraphy, age and high blood pressure were risk factors for higher impairment in PDB. The subjects with PDB showed more profound and a higher proportion of conductive hearing loss than the control group. The patients with PDB and skull involvement presented a more severe hearing loss compared with the subjects without skull involvement. Skull involvement and age were found to be risk factors for hearing loss. Copyright © 2018 Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello.

Case-Control study design is a type of observational study. In this design, participants are selected for the study based on their outcome status. Thus, some participants have the outcome of interest (referred to as cases), whereas others do not have the outcome of interest (referred to as controls). The investigator then assesses the exposure in both these groups. The investigator should define the cases as specifically as possible. Sometimes, definition of a disease may be based on multiple criteria; thus, all these points should be explicitly stated in case definition. An important aspect of selecting a control is that they should be from the same 'study base' as that of the cases. We can select controls from a variety of groups. Some of them are: General population; relatives or friends; and hospital patients. Matching is often used in case-control control studies to ensure that the cases and controls are similar in certain characteristics, and it is a useful technique to increase the efficiency of the study. Case-Control studies can usually be conducted relatively faster and are inexpensive - particularly when compared with cohort studies (prospective). It is useful to study rare outcomes and outcomes with long latent periods. This design is not very useful to study rare exposures. Furthermore, they may also be prone to certain biases - selection bias and recall bias.

Background and objective The study is based on hypothesis that whether continuous entomological surveillance of Ae. aegypti and simultaneous appropriate interventions in key containers during non-transmission (December–May) months would have any impact on breeding of Aedes and dengue cases during the following transmission months (June–November). The impact of the surveillance and intervention measures undertaken during non-transmission months were assessed by entomological indicators namely container index (CI), house index (HI), pupal index (PI) and breteau index (BI). Methods A total of 28 localities of West Zone of Delhi with persistent dengue endemicity were selected for the study. Out of these localities, 20 were included in study group while other 8 localities were in control group. IEC and various Aedes breeding control activities were carried out in study group in both non-transmission and transmission season whereas control group did not have any such interventions during non-transmission months as per guidelines of MCD. These activities were undertaken by a team of investigators from NIMR and SDMC, Delhi. In control group, investigators from NIMR carried out surveillance activity to monitor the breeding of Aedes mosquito in localities. Results Comparison of baseline data revealed that all indices in control and study group of localities were comparable and statistically non-significant (p>0.05). In both study and control groups, indices were calculated after pooling data on seasonal basis, i.e., transmission and non-transmission months for both years. The test of significance conducted on all the four indices, i.e., HI, PI, CI, and BI, revealed a significant difference (p<0.05) between the study group and control group during transmission and non-transmission months except in HI. Due to consistent intervention measures undertaken in non-transmission months in study group, reduction in CI, HI, BI and PI was observed 63%, 62%, 64% and 99% respectively during transmission months as compared to control group where increase of 59%, 102%, 73% and 71% respectively. As a result of reduction in larval indices, no dengue case (except one NS1) was observed in study group, whereas 38 dengue cases were observed in control group. Conclusion Through this pilot study, it is concluded that proper intervention in non-transmission season reduces vector density and subsequently dengue cases in transmission season. PMID:27918577

The purpose of this study was to explore the effects of case-based learning on communication skills, problem-solving ability, and learning motivation in sophomore nursing students. In this prospective, quasi-experimental study, we compared the pretest and post-test scores of an experimental group and a nonequivalent, nonsynchronized control group. Both groups were selected using convenience sampling, and consisted of students enrolled in a health communication course in the fall semesters of 2011 (control group) and 2012 (experimental group) at a nursing college in Suwon, South Korea. The two courses covered the same material, but in 2011 the course was lecture-based, while in 2012, lectures were replaced by case-based learning comprising five authentic cases of patient-nurse communication. At post-test, the case-based learning group showed significantly greater communication skills, problem-solving ability, and learning motivation than the lecture-based learning group. This finding suggests that case-based learning is an effective learning and teaching method. © 2014 Wiley Publishing Asia Pty Ltd.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

To observe the clinical effects of using hyperbaric oxygen comprehensive therapy for the treatment of noise induced deafness. From May 2009 to April 2012 in our hospital 220 cases of noise induced deafness patients were chosen and they were all construction workers; According to different treatments all patients were divided into the control group (110 cases) only having hyperbaric oxygen treatment and the treatment group (110 cases) using hyperbaric oxygen comprehensive therapy, including control group simply by. Hearing improvements of the two groups were recorded and compared. The cure rate of the comprehensive therapy group was 53.6%which was higher than that of the control group 38.2% (χ(2) = 5.290, P < 5.290), while the total effective rate of the comprehensive therapy group was 79.1%which was also significantly higher than that of the control group 67.3% (χ(2) = 3.914, P < 0.05). After two courses of comprehensive treatment the cure rate and total effective rate were 47.3%and 73.6%respectively, while after four courses of comprehensive treatment group the cure rate and total effective rate turned to be 60.9% and 84.5% respectively, which had significant difference (χ(2) values were 4.118 and 3.958, P < 0.05). The cure rate and total effective rate of the comprehensive therapy group are higher than the simple hyperbaric oxygen treatment group, which is worthy of clinical application and promotion in the future.

To investigate whether the microscopic filamentous aggregates observed in radicular cysts are associated with the molecular identification of Actinomyces israelii. Moreover, to verify whether this bacterium can be detected in radicular cyst specimens not presenting aggregates. Microscopic colonies suggestive of Actinomyces were found in 8 out of 279 radicular cyst samples (case group). The case and control groups (n = 12; samples without filamentous colonies) were submitted to the semi-nested polymerase chain reaction to test the presence of A israelii. DNA sequencing was performed to validate polymerase chain reaction results. Two and 3 samples in the case and control groups, respectively, did not present a functional genomic DNA template and were excluded from the study. A israelii was identified in all samples of the case group and in 3 out of 9 samples of the control group. Although A israelii is more commonly identified in radicular cysts presenting filamentous aggregates, it also appears to be detected in radicular cysts without this microscopic finding.

We set out to determine which patients admitted for expectant management of early onset severe pre-eclampsia develop abruptio placentae and to compare the perinatal mortality rate of patients who developed abruptio placentae with those who did not have this complication. This was a case controlled study, using gestational age at delivery to select a control group for 69 patients who developed abruptio placentae. The only significant difference on admission was the higher uric acid levels in patients who developed abruptio placentae. Mean admission to delivery intervals were 11.9 and 8.8 days for the control and abruption groups respectively (P = 0.0083). Fifty-eight per cent of the babies in the abruptio placentae group developed late decelerations, as determined by fetal heart rate monitoring compared with 32% in the control group. Lactate dehydrogenase levels before delivery were significantly higher in the abruption group, but it only became elevated shortly before delivery and in the minority of cases. There were two intrauterine and four neonatal deaths in the abruption group and two neonatal deaths in the control group. Late decelerations detected by frequent fetal heart rate monitoring in patients with early onset severe pre-eclampsia is the only early warning of abruptio placentae.

This case-control study aimed to test the association between voice disorders and job stress among public schoolteachers in São Paulo, Brazil. The groups consisted of teachers with (n = 165) and without (n = 105) voice-related complaints. Both groups answered the questionnaires Conditions of Vocal Production and Job Stress Scale. Analysis of cases and controls showed comparable samples, differing only by vocal symptoms. There was a statistically significant difference between cases and controls in relation to job stress involving high strain (OR = 2.1; 95%CI: 1.1-3.9), which places high demands combined with low job control. High strain in cases in this study represents the highest risk of physical and mental disorders for teachers. Loss of voice prevents teachers from continuing in their professional role, eliminates their professional identity, and jeopardizes their career.

Cardiovascular implantable electronic device (CIED) infections are associated with morbidity and mortality. Peri-operative systemic intravenous antibiotic prophylaxis reduces the rate of CIED infections. AIGIS Rx , a polymer envelope implanted with the CIED, releases minocycline and rifampin, and has been introduced to reduce infections. Retrospective review of 184 patients who underwent CIED implantation was conducted. Ninety-two patients were implanted with an AIGIS Rx envelope (AIGIS Rx group) and 92 patients were not implanted with an AIGIS Rx envelope (control group). Data were collected on demographics and risk factors for CIED infections (i.e. congestive heart failure, renal insufficiency, chronic kidney disease, oral anticoagulant use, chronic steroid use, need for lead replacement or revision, temporary pacing, early re-intervention, and having more than two leads in place). Rates of implantation success, major infections and mortality were compared between the AIGIS Rx group and the control group. The AIGIS Rx group had longer hospitalizations (6.8±10.7 days vs 3.1±5.2 days; P=0.001), higher chronic corticosteroid use, higher rates of replacement or revision (51.1% vs 8.7%; P=0.001), and a greater proportion of devices with more than two intracardiac leads (42.4% vs 29.3%; P=0.03) than the control group. Successful implantation occurred in 97% of patients in both groups. Major infection was seen in 5.4% of cases in the AIGIS Rx group and 1.1% of cases in the control group (P=0.048). Device removal was conducted in 3.3% of cases in the AIGIS Rx group compared with 1.1% of cases in the control group (P=0.16). There were two deaths in the AIGIS Rx group. Organisms cultured were meticillin-resistant Staphylococcus aureus, meticillin-susceptible S. aureus and Enterococcus faecalis. The AIGIS Rx group had higher rates of major infection but also higher risk factors compared with the control group. The rate of device extraction and CIED-related mortality was higher in the AIGIS Rx group than in the control group. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd.

To evaluate the possible selection bias related to the differential participation of mobile phone users and non-users in a Finnish case-control study on mobile phone use and brain tumors. Mobile phone use was investigated among 777 controls and 726 cases participating in the full personal interview (full participants), and 321 controls and 103 cases giving only a brief phone interview (incomplete participants). To assess selection bias, the Mantel-Haenszel estimate of odds ratio was calculated for three different groups: full study participants, incomplete participants, and a combined group consisting of both full and incomplete participants. Among controls, 83% of the full participants and 73% of the incomplete participants had regularly used a mobile phone. Among cases, the figures were 76% and 64%, respectively. The odds ratio for brain tumor based on the combined group of full and incomplete participants was slightly closer to unity than that based only on the full participants. Selection bias tends to distort the effect estimates below unity, while analyses based on more comprehensive material gave results close to unity.

In 1997, the number of newly registered patients with pulmonary tuberculosis increased, compared with that in 1996, in Japan. The majority of the increase were occupied by elder patients 70 years of age or higher. But in younger group less than 30 years old, a reduction in the incidence of tuberculosis had been slowed down, until 1996. The purpose of this report is to elucidate the characteristics of these younger patients. 139 cases younger than 30 years of age, who were hospitalized in the tuberculous ward of IMCJ from April 1995 to March 1998, were investigated, and were compared with the control group (557 cases), 30-79 years old who were hospitalized during the same period. In the younger group, the proportion of women cases, discovered by health examination, foreigners, and contact with TB patients in the past was significantly higher than in the control group. But there were no difference between the both groups, concerning the proportion of those spending irregular life or living alone. The proportion of sputa smear negative cases was significantly higher in the younger group than in the control. For early diagnosis of TB among younger group, the application of bronchofiberscopy and nucleic acid diagnostic method, are encouraged.

The aim of this study is to identify the effects of a case management program on knowledge about oral cancer, preventive behavior for oral cancer, and level of uncertainty for patients with oral precancerous lesions. A randomized controlled trial was conducted with two groups, using a pre- and posttest design. The experimental group received a case management program and telephone follow-up sessions; the control group received routine care. Patients were assessed at three time points: first visit to the otolaryngology clinic for biopsy examination (T0), and then at 2 weeks (T1) and 4 weeks (T2) after the biopsy examination. Patients in both groups had significantly higher levels of knowledge about oral cancer, preventive behavior for oral cancer, and lower level of uncertainty at T2 compared to T0. At T2, participants in the experimental group had significantly greater knowledge about oral cancer, more preventive behavior for oral cancer, and less uncertainty compared to those in the control group. The case management program with telephone counseling effectively improved knowledge about oral cancer, preventive behavior for oral cancer, and uncertainty levels in patients with oral precancerous lesions in the four weeks after receiving a biopsy examination. The case management program can be applied with positive results to patients receiving different types of cancer screening, including colorectal, breast, and cervical screening.

Objective: The research sought to determine whether case discussion at residents' morning report (MR), accompanied by a computerized literature search and librarian support, affects hospital charges, length of stay (LOS), and thirty-day readmission rate. Methods: This case-control study, conducted from August 2004 to March 2005, compared outcomes for 105 cases presented at MR within 24 hours of admission to 19,210 potential matches, including cases presented at MR and cases not presented at MR. With matching criteria of patient age (± 5 years), identical primary diagnosis, and secondary diagnoses (within 3 additional diagnoses) using International Classification of Diseases (ICD-9) codes, 55 cases were matched to 136 controls. Statistical analyses included Student's t tests, chi-squared tests, and nonparametric methods. Results: LOS differed significantly between matched MR cases and controls (3 days vs. 5 days, P < 0.024). Median total hospital charges were $7,045 for the MR group and $10,663 for the control group. There was no difference in 30-day readmission rate between the 2 groups. Discussion/Conclusion: Presentation of a case at MR, followed by the timely dissemination of the results of an online literature review, resulted in a shortened LOS and lower hospital charges compared with controls. MR, in association with a computerized literature search guided by the librarians, was an effective means for introducing evidence-based medicine into patient care practices. PMID:17971885

Plantar fasciitis is the most common cause of heel pain. Extracorporeal shock wave therapy (ESWT) is an alternative treatment for refractory cases of plantar fasciitis. Studies also demonstrated that ESWT may be an appropriate treatment for myofascial trigger points. This study was designed to evaluate its effectiveness by comparing the ESWT of Gastrocnemius/Soleus (gastroc-soleus) trigger points and heel region with the ESWT of the heel region alone. The study was carried out among 40 patients with a clinical diagnosis of plantar fasciitis, divided randomly to case (n = 20) and control (n = 20) groups. The case group received ESWT for the heel region and for the gastroc-soleus trigger points. The control group received ESWT just for the heel region. The protocol was the same in both groups and they were treated for three sessions every week. The pain score (100 mm visual analog score [VAS]) and the modified Roles and Maudsley score was evaluated before the first session and eight weeks after the last session. Eight weeks after the last session, although the mean VAS had decreased significantly in both groups, this decrement was more significant in the case group. (P = 0.04). According to the modified Roles and Maudsley score, there was a significant improvement in both the case (P < 0.001) and control (P = 0.01) groups, eight weeks after treatment, but there were significantly better results in the case group. The combination of ESWT for both plantar fasciitis and gastroc-soleus trigger points in treating patients with plantar fasciitis is more effective than utilizing it solely for plantar fasciitis.

To determine the prevalence and typing of HPV DNA in pregnant women with a diagnosis of atypical squamous cells (ASC) and to assess whether pregnancy-related changes contribute to the diagnosis of ASC. HPV testing was performed on residual specimens from the ThinPrep Pap test (Cytyc Corp., Boxborough, Massachusetts, U.S.A.) in pregnant women diagnosed as ASC (study group, n = 105), low and high grade squamous intraepithelial lesion (LSIL and HSIL) (positive control, n = 33) and negative for epithelial cell abnormality (negative control, n = 20). All cases were reviewed by 2 cytopathologists to obtain consensus diagnoses using the Bethesda System 2001 criteria. The study group cases were further subcategorized into ASC of undetermined significance (ASCUS, n = 99) and ASC cannot exclude HSIL (ASC-H, n = 6). HPV testing was also performed on an ASC control group consisting of 68 consecutive ASC cases in nonpregnant women, matched by age. Mean patient age was 23.7 years for the study group and 25.6 years for the ASC control group. HPV DNA was detected in 88.6% of cases in the study group, including 87.9% of ASC-US and 100% of ASC-H cases. Of the HPV positive cases, 79.6%, 4.3%, 5.4% and 10.8% had high-risk, mixed high- and low-risk, low-risk and unknown HPV types, respectively. The most frequent HPV types detected were: types 52 (31.2%), 16 (15.1%), 39 (11.8%), 53 (10.8%), and 18 and 58 (9.7% each). Multiple viral types were detected in 43.0% of cases. The prevalence of HPV DNA in the positive and negative controls in pregnant women was 100% and 55%, respectively. HPV DNA was detected in 83.8% of the ASC control group. Regardless of pregnancy-related changes, the prevalence of HPV DNA in pregnant women (88.6%) was similar to that found in ASC in nonpregnant women of the same reproductive-age group (83.8%), and the high-risk types accounted for the vast majority of cases (83.9%). These findings demonstrate that pregnancy-related changes do not contribute to the diagnosis of ASC in this subset of women. Furthermore, the high HPV DNA prevalence in reproductive-age women (< 40 years) suggests that HPV testing may have limited utility in effective management of these patients.

To study whether reported, but inconsistent, associations between the FMR1 CGG repeat lengths in the intermediate, high normal, or low normal range differentiate women diagnosed with diminished ovarian reserve (DOR) from population controls and whether associations vary by race/ethnic group. Case-control study. Academic and private fertility clinics. DOR cases (n = 129; 95 Whites, 22 Asian, 12 other) from five U.S. fertility clinics were clinically diagnosed, with regular menses and no fragile X syndrome family history. Normal fertility controls (n = 803; 386 Whites, 219 African-Americans, 102 Japanese, 96 Chinese) from the United States-based SWAN Study had one or more menstrual period in the 3 months pre-enrollment, one or more pregnancy, no history of infertility or hormone therapy, and menopause ≥46 years. Previously, the SWAN Chinese and Japanese groups had similar FMR1 CGG repeat lengths, thus they were combined. None. FMR1 CGG repeat lengths. Median CGG repeats were nearly identical by case/control group. DOR cases had fewer CGG repeats in the shorter FMR1 allele than controls among Whites, but this was not significant among Asians. White cases had fewer CGG repeats in the shorter allele than Asian cases. No significant differences were found in the high normal/intermediate range between cases and controls or by race/ethnic group within cases in the longer allele. This study refutes prior reports of an association between DOR and high normal/intermediate repeats and confirms an association between DOR and low normal repeats in Whites.

The long time use of opium has some effects on serums biochemical factors, the determination of this variation is a new approach in understanding off addiction and relive of drug abuser health. Hence in this study, these indicators in person who were withdrawing of opium have been studied. In this cross-sectional study bloods biochemical factors such as fasting blood sugar (FBS), sodium (Na), calcium (Ca), uric acid (UA), blood urea nitrogen (BUN), creatinine, cholesterol, total protein, and fibrinogen in three groups serum were studied: (1) Who had been permanent opium users more than 2 years (case). (2) Dependent person who has taken one month addiction withdrawal course (control). (3) A healthy group that had been demographically similar to the other groups. According to these study findings, FBS serum level in the case group is lower than control group. Serum level of Na, creatinine, and blood triglyceride (TG) in case study are higher than group control. Concentration of potassium, Ca, UA, BUN, cholesterol, total serum protein, fibrinogen, and thrombin time in case study and group control showed no significant difference. Also, in withdrawing case serum level of Na, Ca, UA, BUN, creatinine, and TG significantly increase and thrombin time decrease. According to this study not only the longtime use of opium but also opium with drawerin opium dependent people can change their serum biochemical factors. So recognition, treatment, and prevention of this change could be a new step in improving of health and condition of patients.

To compare the effect of An's Shaobei Injection ([symbols; see text]) with Xiaozhiling Injection ([symbols; see text]) in patients with internal hemorrhoids of grade I-III. This cohort study included 1,520 internal hemorrhoids patients with grade I-III who were scheduled for liquid injection treatment from July 2003 to July 2009. The cohort included patients who underwent either An's Shaobei Injection treatment (the treatment group, 760 cases) or Xiaozhiling Injection treatment (the control group, 760 cases). All patients were followed up regularly for 3 years; the observing indices included anal function recovery and clinical response after operation. Among the 1,520 patients, 1,508 (99.2%) completed the 3-year follow-up. The efficacy rate was 97.5% in the treatment group, significantly higher than the control group (91.8%, P<0.01). The recurrence rate in the treatment group was 0.5%, significantly lower than that of the control group (1.3%, P<0.01). In addition, perianal callosity occurred in 8 cases (1.1%) and anorectal stricture in 26 cases (3.5%) after operation in the control group. There was no perianal callosity and anorectal stricture in the treatment group. The treatment with An's Shaobei Injection demonstrated superior clinical effect to Xiaozhiling Injection with fewer adverse effects.

To investigate the incidence of adverse pregnancy outcomes in couples with an unexplained Recurrent Pregnancy Loss (RPL) history, a retrospective cohort study was conducted between 2014 and 2015. The study group (A) included couples with an unexplained RPL, and the control group (B) was composed of couples who attended the Low-Risk Antenatal Unit during the same period. On the other hand, 53 couples were included in the study group (A) and on the other hand, 65 in the control group (B). Women with previous unexplained recurrent pregnancies loss had a significantly increased risk of gestational diabetes with 12 cases (22.6%) in the study group and 3 cases (4.6%) in the control (OR: 6.048; 95% CI: 1.607-22.762; p = 0.007). A slight increase in the risk of preterm delivery and hepatic cholestasis was observed in the study group (6 cases, 11.3%, in study group and 1 case, 1.5% in the controls (OR: 8.170; 95% CI: 0.951-70.158; p = 0.0555). Women with a history of RPL delivered more frequently by caesarean section (OR: 3.252; 95% CI: 1.460-7.241; p = 0.0039). Women with a history of RPL were at an increased risk for adverse pregnancy outcomes, mainly gestational diabetes. Therefore, a closer surveillance during the antenatal period is recommended in this group of patients.

This study was aimed to evaluate the role of toxoplasmosis in etiology of abortion and stillbirth based on molecular and serological techniques. A total of 110 pregnant women with abortion and stillbirth were enrolled as the case group, and 110 pregnant women with normal delivery were enrolled as the control group. Serological and molecular detections of Toxoplasma gondii were assessed by ELISA and PCR methods. The seroprevalence of IgG was 25.5% in the case group (26.8% in abortion and 21.4% in stillbirth) and 26.4% in the control group. IgM seropositivity was detected in 2.7% of the case group (3.6% in abortion and 0% in stillbirth) and 0.9% of the control group (p = 0.37). Toxoplasma gondii DNA was detected in 6.4% of the case group (7.3% in abortion and 3.6% in stillbirth) and 1.8% of the control group by PCR (p = 0.17). The major risk factor of congenital toxoplasmosis was the history of eating undercooked meat (p = 0.06). Results of this study revealed that the rate of PCR positive in women with abortion and stillbirth was 3.7 times higher than that in normal delivery, but the difference was not statistically significant. These findings suggest that toxoplasmosis can be involved in etiology of abortion and stillbirth.

To evaluate the short-term efficacy and safety of Bushen Shuji Granule (BSG) in treating ankylosing spondylitis (AS) patients. A prospective randomized controlled clinical trial was carried out in 62 active stage AS patients with Shen deficiency Du-channel cold syndrome (SDDCS), who were randomly assigned to the BSG group (treated with BSG) and the control group (treated with Celecoxib Capsule). Twelve weeks consisted of one therapeutic course. Therapeutic effects were evaluated by ASAS20 and ASAS40 (set by Assessments in Ankylosing Spondylitis working group) , BASDA150, Chinese medical (CM) syndrome efficacy evaluation standards. BASDAI, the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath AS Metrology Index (BASMI), scores for spine pain, scores for pain at night, patient global assessment (PGA) , erythrocyte sedimentation rate (ESR) , and C reactive protein (CRP) were observed before and after treatment. After three-month treatment by BSG, ASAS20 standard rate was 63. 33% (19/30 cases) in the BSG group and 66.67% (20/30 cases) in the control group with no significant difference between the two groups (χ2 = 0.073, P > 0.05). The efficacy for CM syndromes was 70.00% (21/30 cases) in the BSG group, higher than that in the control group [40.00% (12/30 cases), χ2 = 5.455, P < 0.05]. Scores for CM syndromes, BASDAI, night pain index, spinal pain index, PGA, CRP were improved in the BSG group (P < 0.05, P < 0.01). The incidence of adverse events in the BSG group was lower than that of the control group. BSG based on Shen supplementing, Du-channel strengthening, blood activating, and channels dredging method had good short-term clinical efficacy and safety in treating AS.

The aim of this study was to investigate the oral health status of women with high-risk pregnancies. A case-control study of 142 pregnant women was conducted. The case group included 81 pregnant women with high-risk pregnancies, while 61 women with normal pregnancies served as controls. The following variables were recorded for each woman: age, general health status, DMF, CPITN, and PBI index, amounts of Streptococcus mutans in the saliva and dental treatment needs. The Mann-Whitney test, Kruskal-Wallis test, t-test and chi-squared test were used for statistical analyses. Statistically significant differences were detected between the PBI indices and dental treatment needs of the two groups. Out of the entire study cohort, 77% of the women in the case group and 52% of the women in the control group required dental treatment. In this study, women with complications during pregnancy had severe gingivitis and needed more frequent dental treatment than those in the control group.

Background We report the development of a cutaneous melanoma risk algorithm based upon 7 factors; hair colour, skin type, family history, freckling, nevus count, number of large nevi and history of sunburn, intended to form the basis of a self-assessment webtool for the general public. Methods Predicted odds of melanoma were estimated by analysing a pooled dataset from 16 case-control studies using logistic random coefficients models. Risk categories were defined based on the distribution of the predicted odds in the controls from these studies. Imputation was used to estimate missing data in the pooled datasets. The 30th, 60th and 90th centiles were used to distribute individuals into four risk groups for their age, sex and geographic location. Cross-validation was used to test the robustness of the thresholds for each group by leaving out each study one by one. Performance of the model was assessed in an independent UK case-control study dataset. Results Cross-validation confirmed the robustness of the threshold estimates. Cases and controls were well discriminated in the independent dataset (area under the curve 0.75, 95% CI 0.73-0.78). 29% of cases were in the highest risk group compared with 7% of controls, and 43% of controls were in the lowest risk group compared with 13% of cases. Conclusion We have identified a composite score representing an estimate of relative risk and successfully validated this score in an independent dataset. Impact This score may be a useful tool to inform members of the public about their melanoma risk. PMID:25713022
Population versus hospital controls for case-control studies on cancers in Chinese hospitals
2011-01-01
Background Correct control selection is crucial to the internal validity of case-control studies. Little information exists on differences between population and hospital controls in case-control studies on cancers in Chinese hospital setting. Methods We conducted three parallel case-control studies on leukemia, breast and colorectal cancers in China between 2009 and 2010, using population and hospital controls to separately match 540 incident cases by age, gender and residency at a 1:1 ratio. Demographic and lifestyle factors were measured using a validated questionnaire in face-to-face interview. Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained using conditional logistic regression analyses. Results The two control groups had closely similar exposure distributions of 15 out of 16 factors, with the only exception being that hospital controls were less likely to have a BMI ≥ 25 (OR = 0.71, 95% CI: 0.54, 0.93). For exposure of green tea drinking, the adjusted ORs (95% CIs) comparing green tealeaves intake ≥ 1000 grams annually with non-drinkers were 0.51 (0.31, 0.83) and 0.21 (0.27, 0.74) for three cancers combined, 0.06 (0.01, 0.61) and 0.07 (0.01, 0.47) for breast cancer, 0.52 (0.29, 0.94) and 0.45 (0.25, 0.82) for colorectal cancer, 0.65 (0.08, 5.63) and 0.57 (0.07, 4.79) for leukemia using hospital and population controls respectively. Conclusions The study found that hospital controls were comparable with population controls for most demographic characteristics and lifestyle factors measured, but there was a slight difference between the two control groups. Hospital outpatients provide a satisfactory control group in hospital-based case-control study in the Chinese hospital setting. PMID:22171783

Oral cancer is one of the most common cancers in the world. Although multifactorial, the exact pathogenesis of oral cancer is still unclear. Apart from tobacco chewing and smoking, chronic long-term irritation by ill-fitting denture is also said to be an important risk factor for the development of oral cancer. Literature quotes some amount of evidence that correlates long-term denture irritation as a risk factor for the development of oral cancer. Hence, we analyzed the correlation of denture-related sores as a risk factor for the development of oral cancer. The present case-control study included 140 newly diagnosed oral cancer cases and 140 patients as the control healthy group. One-hour questionnaire was framed and was conducted to the control group and the study group by 10 experienced interviewers who were trained for such type of analysis. Assessment of the patients' socioeconomic status, cigarette smoking habit, alcohol drinking habit, and oral health status was done and compared on the two study groups. Logistic regression models along with multivariate models were used for the assessment of the results. In the control group and the cancer patient group, total of 140 new cancer cases and 140 subjects were included. Out of 140 patients in the cancer group, 16 were nonsmokers, while 110 smoked cigarette in the cancer patient group. As far as alcohol consumption is concerned, 42 patients in the control group and 102 patients in the oral cancer group were chronic heavy drinkers. Fried food intake was high in both the groups. Significant correlation was obtained while comparing the heavy smokers, heavy alcohol consumers, and oral health status in both the study groups. Our results favor the hypothesis that positive correlation exists between oral cancer risk and recurrent denture sores. People wearing denture prosthesis should be periodically visualized for identification of any mucosal alteration or changes at the earliest.

Association of keratoconus (KC) with genetic predisposition and environmental factors has been well documented. However, no single study has investigated the possible relationship between ABO and Rh blood groups and KC. A case-control study was designed in a university hospital enrolling 214 patients with KC in the case group and equal number of age- and sex-matched healthy subjects in the control group. Primary characteristics, ABO blood group, and Rh factors were compared between the two groups. Topographic findings of KC eyes and the severity of the diseases were investigated according to the distribution of the blood groups. Blood group O and Rh(+) phenotype were most frequent in both groups. There was no significant difference between the two groups in terms of ABO blood groups or Rh factors. Mean keratometery (K), central corneal thickness, thinnest corneal thickness, flat K, steep K, sphere and cylinder, spherical equivalent, and uncorrected visual acuity were all similar between ABO blood groups and Rh(+) and Rh(-) groups. However, the best spectacle-corrected visual acuity (BCVA) had the highest value in AB blood group (0.35 ± 0.22 logMAR, P=0.005). Moreover, the blood group AB revealed the highest frequency for grade 3 KC, followed by grades 1, 2, and 4 (P=0.003). We observed no significant excess of any particular blood group among KC cases compared with healthy subjects. Except BCVA, none of the keratometric or topographic findings was significantly different between blood groups.

We have used biochemical assays to examine cingulate and occipital cortices from age-matched cases of Alzheimer's disease (AD; n = 12), senile dementia of the Lewy body type (SDLT; n = 13), Parkinson's disease (PD; 5 non-demented cases and 7 cognitively impaired cases) and controls (n = 11) for paired helical filaments (PHFs), phosphorylated and normal tau protein and beta/A4-protein. Whereas cingulate cortex is characterised by relatively high densities of cortical Lewy bodies in the SDLT cases and lower numbers in PD, these inclusion bodies were absent in the cingulate cortex from AD and control cases. Protease-resistant PHFs and hyperphosphorylated tau protein were found in AD and, at low levels, in a minority of SDLT cases. Qualitatively, both of these preparations were indistinguishable in SDLT from those found in AD but levels of both parameters in SDLT were less than 5% of those in AD. SDLT, PD and control groups did not differ from each other in terms of the quantity of protease-resistant PHFs or the level of hyperphosphorylated tau. Furthermore, PHF accumulation did not distinguish between PD cases with or without dementia. The levels of normal tau protein did not differ between the four groups. beta/A4 protein levels did not distinguish between PD and control groups, between AD and SDLT groups, or between SDLT and control groups for either cingulate or occipital cortices. Thus extensive accumulation of PHFs in either neurofibrillary tangles or dystrophic neurites is not a feature of either SDLT or PD. Our findings provide molecular support for the neuropathological and clinical separation of SDLT as a form of dementia that is distinct from AD.

Older adults are underrepresented in medical research for many reasons, including recruitment difficulties. Recruitment of older adults for research studies is often a time-consuming process and can be more challenging when the study involves older adults with unique exposures to traumatic events and from minority groups. The current article provides a brief overview of (a) challenges encountered while recruiting aging women Holocaust survivors for a case control study and (b) strategies used for meeting those challenges. The case group comprised women Holocaust survivors who were recently diagnosed with breast cancer and the control group comprised healthy women from a Holocaust-survivor community in Israel.

The endoscopic technique has been utilized to harvest muscle flaps and detect perforators of fasciocutaneous flaps. This study aimed to compare the perioperative outcomes between the endoscope-assisted technique and handheld acoustic Doppler for perforator identification in fasciocutaneous flaps.This retrospective case-control study included patients who underwent fasciocutaneous flap reconstruction for traumatic soft tissue defects. In the case group, perforator identification was assisted by the endoscope-assisted technique. In the control group, age- and sex-matched patients received handheld acoustic Doppler to detect perforators. Perioperative outcomes, flap characteristics, and postoperative complications were compared.There were 12 patients in the case group and 12 in the control group. Compared with the control group, the case group had a significantly shorter length of donor-site wounds (9 cm vs 12 cm, P = .023) and a significantly smaller proportion of patients receiving skin grafting at the donor sites (0% vs 41.7%, P = .037). The case group had a longer operative time, but the difference was not statistically significant (180 minutes vs 150 minutes, P = .367). The amount of blood loss, the time length of postoperative drainage, and complications did not significantly differ between the 2 groups.The endoscope-assisted technique for perforator identification of fasciocutaneous flaps provided less donor-site morbidity and a significantly shorter length of donor-site wounds than the conventional handheld acoustic Doppler, which suggests that this technique could be a valuable alternative when a precise design is indicated.

Circumpatellar electrocauterization to destroy pain receptors during total knee arthroplasty without patellar resurfacing is commonly used to decrease postoperative knee pain. We aimed to evaluate the effect of denervation with electrocauterization on patellar cartilage. Twenty rabbits were randomly assigned to two equally sized case and control groups. The rabbits in the case group underwent surgery via the anterior midline skin incision and medial parapatellar arthrotomy, followed by denervation electrocauterization at a depth of 1 mm and a distance of 3 mm from the outer border of the patella. In the control group, surgery was identical to that performed in the case group, but without patellar denervation. Twelve weeks after surgery, all rabbits were sacrificed. Range of motion, macroscopic evaluation of cartilage using modified Outerbridge scoring, and histopathological assessment using a modified histologic scoring system for cartilage were evaluated. Three rabbits died during the study. Nine cases and eight animals from the control group were included in the final evaluation. All rabbits had passive full range of motion. Mean Outerbridge score was 2.0 in the case group and 0.37 in the control group (p=0.002). There were statistically significant differences in cellularity (p=0.016), loss of matrix (p=0.004), and clustering of chondrocytes (p=0.008) between the two groups. Microscopic variables as a whole were statistically significant (p=0.001). Circumpatellar electrocauterization may result in cartilage destruction. So, we encourage caution in using routine electrocauterization in patients undergoing total knee arthroplasty. level II. Copyright © 2014 Elsevier B.V. All rights reserved.

A bidirectional relationship exists between diabetes and periodontitis. In the present clinical trial, we evaluated the effects of non-surgical periodontal therapy (NSPT) on insulin resistance in patients with type II diabetes mellitus (DM) and chronic periodontitis. Forty chronic periodontitis patients with type II DM were selected and equally allocated to case and control groups. All patients were assessed for periodontal parameters and systemic parameters. The case group received NSPT, and both groups were re-evaluated after 3 months. All periodontal parameters were found to be significantly improved in the case group compared to the control group 3 months after NSPT. The mean differences in systemic parameters, such as fasting serum C-peptide, Homeostasis Assessment (HOMA) Index-insulin resistance, and HOMA-insulin sensitivity, from baseline to 3 months for the case group were 0.544 ± 0.73, 0.54 ± 0.63, and -25.44 ± 36.81, respectively; for the control group, they were significant at -1.66 ± 1.89, -1.48 ± 1.86, and 31.42 ± 38.82 respectively (P < 0.05). There was a significant decrease in fasting blood glucose and glycosylated hemoglobin A1c from baseline to 3 months in the case group (P < 0.05). The present study showed that periodontal inflammation could affect glycemic control and insulin resistance. Effective periodontal therapy reduced insulin resistance and improved periodontal health status and insulin sensitivity in patients with type II DM and chronic periodontitis. © 2016 John Wiley & Sons Australia, Ltd.

A total of 64 pregnant women were assigned into two groups of cases and controls. Both groups filled out the Perceived Stress Scale at pre-test. Cognitive-behavioral coping skill training was delivered to the case group. After the end of the intervention, both groups completed the same scale again. The results showed that the mean perceived stress of the cases and controls was 27.77 ± 6.033 and 18.97 ± 3.268, respectively (p = 0.001). Therefore, midwives are recommended to plan educational interventions to decrease perceived stress in pregnant women. © The Author(s) 2015.

Carbapenem-resistant and susceptible Acinetobacter baumannii (CRAB and CSAB) have emerged as serious threats among critically ill neonates. We aimed to identify the risks and outcomes for CRAB and CSAB ventilator-associated pneumonia (VAP) compared with a control group. We performed a retrospective and case-case-control study in a neonatal intensive care unit between 2009 and 2014. The numbers of patients in the CRAB VAP, CSAB VAP, and control groups were 63, 13, and 25, respectively. The mean gestational ages and median birthweights of CRAB VAP, CSAB VAP, and control groups were 33.2, 35.0, and 32.6 weeks and 1800, 2230, and 2245 g, respectively. By multivariate analysis, infants who had a birthweight of 1000-1499 g (P = 0.04), cesarean section (P = 0.01), history of cephalosporin use (P = 0.02), and surfactant replacement (P = 0.01) in CRAB VAP were significantly higher than in the control group. Inborn infant (P = 0.01), reintubation (P = 0.04), and umbilical artery catheterization (P = 0.04) in the CRAB VAP group were significantly more than in the CSAB VAP group. The crude mortality rates (CMRs) of CRAB VAP and CSAB VAP were 15.9% and 7.7%, respectively. By univariate analysis, the CMR, septic shock, and bronchopulmonary dysplasia in CRAB VAP were higher than in the control group. There are very high mortality and short-term morbidity rates in CRAB VAP. Surfactant replacement therapy, fewer cesarean sections, and the reduced use of cephalosporin in very preterm infants may reduce CRAB VAP.

To evaluate the prevalence of tuberculosis (TB) stigma and to determine the relation between socio-demographic characteristics and TB stigma among TB cases and their controls in Gezira State, Sudan. A case-control study design was used. New smear-positive TB patients registered in Gezira State in 2010 (n = 425) and controls who attended the same health facility for other reasons (n < 850) formed the study population. Stigma was measured using a standard modified World Health Organization TB KAP (knowledge, attitudes, practice) instrument. TB stigma did not differ between TB cases and controls; mild stigma was found in both groups. The higher degree of stigma among both groups was significantly associated with higher age, lower level of education, residence in rural areas, unemployment and poor TB awareness, while sex had no association with the degree of stigma in either group. Although TB stigma among the Gezira population was found to be mild, it can affect treatment adherence. Empowering both TB patients and communities by increasing their knowledge through proper education programmes could effectively contribute to the effort of controlling TB in the state.

Different studies underline the use of pre-operative antibiotic prophylaxis in clean surgeries like herniotomy and inguinal orchiopexy. But, the meta-analyses do not recommend nor discard the use of prophylactic pre-operative antibiotics. The scarcity of controlled clinical trials in paediatric population further vitiates the matter. This study assessed the difference in the rate of early post-operative wound infection cases in children who received single dose of pre-operative antibiotics and children who did not receive antibiotics after inguinal herniotomy and orchiopexy. This randomised prospective study was conducted in Paediatric Surgery department of PGIMER Chandigarh. Out of 251 patients, 112 patients were randomised to the case group and 139 were ascribed to the control group. The patients in control group were given a standard regimen of single dose of intravenous antibiotic at the time of induction followed by 3-4 days of oral antibiotic. Case group patients underwent the surgical procedure in similar manner with no antibiotic either at the time of induction or post-operatively. The incidence of surgical site infection in case group was 3.73 % and that in control group was 2.22%. The observed difference in the incidence of surgical site infection was statistically insignificant (P value = 0.7027). The overall infection rate in case and control group was 2.89%. Our preliminary experience suggests that there is no statistically significant difference in the proportion of early post-operative wound infection between the patients who received single dose of pre-operative antibiotics and the patients who received no antibiotics after inguinal herniotomy and orchiopexy. The risk of surgical site infection in paediatric heriotomies does not increase even if the child's weight is less than his/her expected weight for age.

Cesarean section (CS) is an independent risk factor for placenta accreta. Some researchers think that the timing of primary cesarean delivery is associated with placenta accreta in subsequent pregnancies. The aim of this study was to investigate the risk of placenta accreta following primary CS without labor, also called primary elective CS, in a pregnancy complicated with placenta previa. A retrospective, single-center, case-control study was conducted at Peking University Third Hospital. Relevant clinical data of singleton pregnancies between January 2010 and September 2017 were recorded. The case group included women with placenta accreta who had placenta previa and one previous CS. Control group included women with one previous CS that was complicated with placenta previa. Maternal age, body mass index, gestational age, fetal birth weight, gravity, parity, induced abortion, the rate of women received assisted reproductive technology, other uterine surgery, and primary elective CS were analyzed between the two groups. The rate of primary elective CS (90.1% vs. 69.9%, P < 0.001) was higher, and maternal age was younger (32.7 ± 4.7 years vs. 34.6 ± 4.0 years, P < 0.001) in case group, compared with control group. Case group also had higher gravity and induced abortions compared with the control group (both P < 0.05). Primary CS without labor was associated with significantly increased risk of placenta accreta in a subsequent pregnancy complicated with placenta previa (odds ratio: 3.32; 95% confidential interval: 1.68-6.58). Women with a primary elective CS without labor have a higher chance of developing an accreta in a subsequent pregnancy that is complicated with placenta previa.

Methodology Series Module 2: Case-control Studies

Case-Control study design is a type of observational study. In this design, participants are selected for the study based on their outcome status. Thus, some participants have the outcome of interest (referred to as cases), whereas others do not have the outcome of interest (referred to as controls). The investigator then assesses the exposure in both these groups. The investigator should define the cases as specifically as possible. Sometimes, definition of a disease may be based on multiple criteria; thus, all these points should be explicitly stated in case definition. An important aspect of selecting a control is that they should be from the same ‘study base’ as that of the cases. We can select controls from a variety of groups. Some of them are: General population; relatives or friends; and hospital patients. Matching is often used in case-control control studies to ensure that the cases and controls are similar in certain characteristics, and it is a useful technique to increase the efficiency of the study. Case-Control studies can usually be conducted relatively faster and are inexpensive – particularly when compared with cohort studies (prospective). It is useful to study rare outcomes and outcomes with long latent periods. This design is not very useful to study rare exposures. Furthermore, they may also be prone to certain biases – selection bias and recall bias. PMID:27057012

The aim of this paper is to present the assessment of a case management project, implemented with chronic patients in Valencia, for the integration of health and social care. This project is linked with the 'Sustainable Socio-Health Model'. Health department 06 in Valencia. The target groups were chronic patients of 65 years and over. A non-randomized non-blinded comparative study with an intervention and control group. The intervention consisted in the creation of an interdisciplinary case management team, the use of a common portfolio of resources, and its application to a pilot sample with an intervention period of 6-9 months. Diseases (ICD-9), functional capacity, use of health and social resources, satisfaction, unit cost services. There was an increase in the combined use of health and social resources in the intervention group, which included social day centers (21.8% in the intervention group compared to 9.8% in the control group), in coordination with primary care (suggested as the only health resource in 55.4% of cases). There was a decrease in the number of medical visits in the intervention group (43.6% versus 74.5% in the control group). Increased patient satisfaction (55.5% in the intervention group compared to 29.4% in the control group) was observed. At least an extra 4.4% of patients were treated using hospital resources without increasing costs. Case management using a common unique portfolio of health and social resources can improve the coordination of resources, increases patient satisfaction and increases the capacity of using of hospital resources.

The purpose of this study was to examine the effects of case-base learning (CBL) using video on clinical decision-making and learning motivation. This research was conducted between June 2009 and April 2010 as a nonequivalent control group non-synchronized design. The study population was 44 third year nursing students who enrolled in a college of nursing, A University in Korea. The nursing students were divided into the CBL and the control group. The intervention was the CBL with three cases using video. The controls attended a traditional live lecture on the same topics. With questionnaires objective clinical decision-making, subjective clinical decision-making, and learning motivation were measured before the intervention, and 10 weeks after the intervention. Significant group differences were observed in clinical decision-making and learning motivation. The post-test scores of clinical decision-making in the CBL group were statistically higher than the control group. Learning motivation was also significantly higher in the CBL group than in the control group. These results indicate that CBL using video is effective in enhancing clinical decision-making and motivating students to learn by encouraging self-directed learning and creating more interest and curiosity in learning.

To evaluate the efficacy of bilateral selective neck dissection of levels II-IV in elective and therapeutic management of the neck as a part of primary surgical treatment of patients with supraglottic laryngeal cancer and clinically negative cervical findings (N0). Institutional, observational, case-control study with historic control of patients who underwent primary supraglottic tumour surgery, and a prospective cohort of patient, who underwent, besides the operation of primary tumour, bilateral selective neck dissection (level II-IV). University, tertiary level hospital, national referral centre. The study included 193 patients with supraglottic cancer and without palpable or ultrasound positive cervical findings who were surgically treated from 1988 to 2005. Besides the operation of primary tumour, all patients in the study group underwent bilateral selective neck dissection (level II-IV). Patients in the control group (N = 51) underwent primary tumour operation only and were followed up regularly. In cases with postoperative regional recurrences, the radical neck dissection was performed. All patients with histopathological confirmation of occult metastases were administered radiotherapy treatment (60 Gy) in the postoperative period. Five-year overall survival rate. Occult cervical metastases were found in 18% of patients. They were present in level II in 77.5%, in level III in 20% of cases and in one patient in level IV (2.5%); the extracapsular spread was observed in 20% of cases. Postoperative regional metastases were found in 4.15% of cases in the study group, and in 11.8% in the control group, which proved to be significantly higher. The five-year overall survival rate showed no significant difference between the study group and the control group. The incidence of postoperative regional recurrences could be reduced by performing bilateral selective neck dissection simultaneously with primary tumour operation, but with no influence on the survival rate. © 2015 John Wiley & Sons Ltd.

Two-year outcomes of patients with schizophrenic disorders who were assigned to an intensive, team-based case management program and patients who received standard psychiatric services were assessed. The case management model featured increased staff contact time with patients, rehabilitation plans based on patients' expressed needs, and patients' attendance at team meetings where their rehabilitation plan was discussed. Forty patients were randomly assigned to either the case management group or the control group that received standard services. Patients' use of emergency and inpatient services, their quality of life, the size of their social networks, and their relatives' burden of care were assessed at assignment to the study groups and at two-year follow-up. Patients in the case management group had significantly fewer emergency visits compared with the two years before the study, and their relatives reported significantly reduced burden of care associated with relationships with psychiatric services over the two-year period. The size of patients' social networks increased for the case management group and decreased for the control group. A team-based intensive case management model is an effective intervention in the rehabilitation of patients with chronic schizophrenia.

To evaluate the effectiveness or acellular dermal matrix (ADM) with autologous buccal micro mucosa and micro skin graft in vaginoplasty. A retrospective analysis was made on the clinical data of 67 patients with vaginal agenesis treated between July 2006 and June 2013. ADM and mixed particles were used in 20 cases (ADM group) and mixed particles graft in 47 cases (control group) in vaginoplasty. There was no significant difference in age between 2 groups (t=0.233, P=0.816). The depth, diameter, and volume of neovagina, epithelization time, stent needing time, and female sexual function index (FSFI) score were compared between 2 groups. There was no significant difference in operation time and amount of bleeding between 2 groups (t = -1.922, P = 0.059; t = 0.398, P = 0.692). The patients were followed up 11-38 months (mean, 16.08 months). Fifteen cases in ADM group and 29 cases in control group had sexual life after operation. Bleeding after operation occurred in 6 cases (2 in ADM group and 4 in control group). No stenosis was observed. Difference in epithelization time was not statistically significant (t = -1.938, P = 0.057). However, the stent needing time of ADM group was significantly shorter than that of control group (t = 7.020, P = 0.000). The neovagina was ideal in wetness degree, smoothness, flexibility, and hairlessness during follow-up. The depth, diameter, and volume of vagina had no significant difference between 2 groups (P > 0.05) at last follow-up, which were close to normal vagina. The other patients had normal sexual function except 1 patient whose FSFI score was less than 23; no statistically significant difference was found in FSFI score between 2 groups (P > 0.05). On the basis of mixed particles grafting, the ADM could improve trestle structure for resisting contracture. The effectiveness is better than merely mixed particles graft. The procedure has satisfactory anatomical and functional results.

In resource constrained settings, immunological assessment through CD4 count is used to assess response to first line Highly Active Antiretroviral Therapy (HAART). In this study, we aim to investigate factors associated with immunological treatment failure. A matched case-control study design was used. Cases were subjects who already experienced immunological treatment failure and controls were those without immunological failure after an exactly or approximately equivalent duration of first line treatment with cases. Data were analyzed using SPSS v16.0. Conditional logistic regression was carried out. A total of 134 cases and 134 controls were included in the study. At baseline, the mean age ± 1 SD of cases was 37.5 ± 9.7 years whereas it was 36.9 ± 9.2 years among controls. The median baseline CD4 counts of cases and controls were 121.0 cells/µl (IQR: 47-183 cells/µl) and 122.0 cells/µl (IQR: 80.0-189.8 cells/µl), respectively. The median rate of CD4 cells increase was comparable for the two groups in the first six months of commencing HAART (P = 0.442). However, the median rate of CD4 increase was significantly different for the two groups in the next 6 months period (M6 to M12). The rate of increment was 8.8 (IQR: 0.5, 14.6) and 1.8 (IQR: 8.8, 11.3) cells/µl/month for controls and cases, respectively (Mann-Whitney U test, P = 0.003). In conditional logistic regressions grouped baseline CD4 count (P = 0.028), old age group and higher educational status (P<0.001) were significant predictors of immunological treatment failure. Subjects with immunological treatment failure have an optimal rate of immunological recovery in the first 6 months of treatment with first line HAART, but relative to the non-failing group the rate declines at a later period, notably between 6 and 12 months. Low baseline CD4 count, old age and higher educational status were associated with immunological treatment failure.

To evaluate the efficacies of modified chitosan, an adhesive prevention substance, as a biological barrier for preventing adhesion after Cesarean section. A total of 250 cases undergoing primary Cesarean section from January 2011 to June 2012 at our hospital were recruited. They were randomly divided into experiment (n = 130) and control (n = 120) groups. The experiment group received modified chitosan during Cesarean section while no adhesive prevention substance was offered for the control group. Postoperative flatus time, postoperative infection and pelvic adhesion were used to evaluate the clinical efficacies. For the experiment group, the average postoperative flatus time was (25 ± 7) hours. Three cases had postoperative infections with a postoperative infection rate of 2.3%. There were 2 cases of pelvic adhesion (pelvic adhesion rate: 1.5%) during the postoperative follow-up period. For the control group, the average postoperative flatus time was (34 ± 11) hours. Five cases had postoperative infections with a postoperative infection rate of 4.2%. There were 5 cases of pelvic adhesion (pelvic adhesion rate: 4.2%) during the postoperative follow-up period. There were significant inter-group differences in postoperative flatus time, postoperative infection and pelvic adhesion (P < 0.05). Modified chitosan can prevent pelvic adhesion after Cesarean section.

To test a virtual case-based Simulated Diabetes Education intervention (SimDE) developed to teach primary care residents how to manage diabetes. Nineteen primary care residency programs, with 341 volunteer residents in all postgraduate years (PGY), were randomly assigned to a SimDE intervention group or control group (CG). The Web-based interactive educational intervention used computerized virtual patients who responded to provider actions through programmed simulation models. Eighteen distinct learning cases (L-cases) were assigned to SimDE residents over six months from 2010 to 2011. Impact was assessed using performance on four virtual assessment cases (A-cases), an objective knowledge test, and pre-post changes in self-assessed diabetes knowledge and confidence. Group comparisons were analyzed using generalized linear mixed models, controlling for clustering of residents within residency programs and differences in baseline knowledge. The percentages of residents appropriately achieving A-case composite clinical goals for glucose, blood pressure, and lipids were as follows: A-case 1: SimDE = 21.2%, CG = 1.8%, P = .002; A-case 2: SimDE = 15.7%, CG = 4.7%, P = .02; A-case 3: SimDE = 48.0%, CG = 10.4%, P < .001; and A-case 4: SimDE = 42.1%, CG = 18.7%, P = .004. The mean knowledge score and pre-post changes in self-assessed knowledge and confidence were significantly better for SimDE group than CG participants. A virtual case-based simulated diabetes education intervention improved diabetes management skills, knowledge, and confidence for primary care residents.

Undergraduate medical teaching in occupational health (OH) is a challenge in universities around the world. Case-based e-learning with an attractive clinical context could improve the attitude of medical students towards OH. The study question is whether case-based e-learning for medical students is more effective in improving knowledge, satisfaction and a positive attitude towards OH than non-case-based textbook learning. Participants, 141 second year medical students, were randomised to either case-based e-learning or text-based learning. Outcome measures were knowledge, satisfaction and attitude towards OH, measured at baseline, directly after the intervention, after 1 week and at 3-month follow-up. Of the 141 participants, 130 (92%) completed the questionnaires at short-term follow-up and 41 (29%) at 3-month follow-up. At short-term follow-up, intervention and control groups did not show a significant difference in knowledge nor satisfaction but attitude towards OH was significantly more negative in the intervention group (F=4.041, p=0.047). At 3-month follow-up, there were no significant differences between intervention and control groups for knowledge, satisfaction and attitude. We found a significant decrease in favourable attitude during the internship in the experimental group compared with the control group. There were no significant differences in knowledge or satisfaction between case-based e-learning and text-based learning. The attitude towards OH should be further investigated as an outcome of educational programmes.

Clinical reasoning is the most important competente in the training process of a physician. To develop a method for teaching clinical reasoning based on prototypes of clinical cases. The study was conducted on sixty-four third year medical students. The study and control groups attended lectures and tutorial sessions with patients. The study group attended additionally discussion seminars of prototypical clinical cases. A clinical reasoning test was applied at the start and end of the learning period to both groups. At the end of the study, the opinions of students of the study group were collected in a focus group. After the learning period, both groups significantly increased their clinical reasoning skills. However, the improvement in the study group was more than double than that of the control group. The absolute improvement in the study group was 30.9%. Students interviewed in the focus group were unanimous in expressing their satisfaction in each and every aspect discussed. The teaching of clinical reasoning to third year medical students by means of pattern recognition in seminars with clinical cases improved significantly their skills.

Our aim is to investigate the effect of active ankle movement to prevent deep vein thrombosis (DVT) in patients who received lower limb surgery, and to provide a theory of evidence for rehabilitation nursing of patients after orthopedic surgery. Between January 2012 and December 2013, a total of 174 patients were randomized as case group (n = 96) and control group (n = 78). Case group received routine nursing and active ankle movement (30 times/min, 1-7 days after surgery), while control group only received routine nursing. The symptoms and signs of DVT were in real-time observation during the experiment. Thigh and crus circumference, maximum venous outflow (MVO), maximum venous capacity (MVC), and MVO ratio (MVO ratio = MVO/MVC) in the two groups were measured 1-7 days after surgery. Six-month follow-up study was also conducted to observe the occurrence of DVT. Our study revealed that thigh circumference in the case group decreased compared with the control group in 5-7 days (fifth day: 39.98 ± 3.25 vs. 41.01 ± 3.38, P = 0.043; sixth day: 38.21 ± 3.81 vs. 39.49 ± 3.79, P = 0.029; seventh day: 37.13 ± 3.15 vs. 38.76 ± 3.31, P = 0.001), and crus circumference in the case group also decreased compared with the control group in 5-7 days (fifth day: 26.35 ± 2.11 vs. 27.01 ± 2.19, P = 0.045; sixth day: 25.99 ± 2.31 vs. 26.88 ± 3.12, P = 0.032; seventh day: 25.56 ± 1.99 vs. 26.38 ± 2.89, P = 0.028). MVO and MVC in the case group increased compared with the control group 7 days after surgery (MVO: 15.01 ± 2.56 vs. 14.12 ± 2.56, P = 0.024; MVC: 10.18 ± 3.15 vs. 8.91 ± 2.78, P = 0.006). Significant difference in the incidence of thrombus and DVT were found between the case group and the control group 1-7 days after surgery (thrombus: 1.0% and 7.7%, P = 0.027; DVT: 7.6% and 18.4%, P = 0.032). Our result manifested that active ankle movement can relieve the swelling of patients after lower limb surgery, and improve the MVO and MVC of patients to prevent formation of DVT after lower limb surgery.

Objective: To explore the efficacy of He-Ne laser intravascular irradiation on infarction and hemorrheology. To observe the effects of intravascular low level He-Ne laser irradiation (ILLLI) of blood on cell proliferation, apoptosis and chromosome in lymphocyte from cerebral infarction Methods: Seventy cases with cerebral infarction were randomly divided into groups control group (35 cases) treated only with common drugs and therapeutic group (35 cases) treated besides common drugs also by He-Ne laser intravascular irradiation. Their hemorrheology index and treatment results were observed and compared. The blood lymphocytes of cerebral infarction were cultured before and after treatment. After that, the mitosis index (MI), cell kinetics index (CKI), sister-chromatid exchanges (SCE) frequencies and apoptosis were determined. Results The therapeutic group was better than the control one. The effective rate in the therapeutic group was 88.6%, in the control one was 65.7%. The viscosity and fibrinogen, etc were better than that in the control group with significant difference (P<0.01). The lymphocyte proliferation index was significantly two increased than the control one (P>0.05) in cerebral infarction patients after treatment; The CKI of lymphocytes had no obvious difference among groups (P>0.05) SCE frequencies of lymphocytes had no statistic significance between control group and ILLLI on (P>0.05). It showed the apoptosis rate of lymphocytes in cerebral infarction patients after ILLLI treatment increased significantly compared with the control group, (P<0.001). There was a significant difference of apoptosis rate of lymphocytes in cerebral infarction patients than the control (P<0.001). Conclusions: During the He-Ne laser intravascular irradiation of the cerebral infarction, the low level He-Ne by ILLLI can increase the proliferation of lymphocytes, and can induce lymphocytes to apoptosis, but has no mutagenicity of cells.

When knee medial collateral ligament (MCL) rupture, the upper surface of medial meniscus is exposed totally, like the gulf panoramic, which is called "panoramic views of the bay sign" or the "bay sign". To investigate the reliability and significance of the "bay sign" in diagnosis of knee MCL rupture under arthroscope. Between March 2007 and March 2011, 127 patients with knees injuries were divided into the observation group (n = 59) and control group (n = 68) based on the MRI results. In the observation group, 59 patients had MCL rupture by MRI, including 12 cases of MCL injury alone, 16 cases of MCL injury with lateral meniscus torn, 27 cases of MCL injury with anterior cruciate ligament (ACL) injury, 3 cases of MCL injury with ACL and posterior cruciate ligament (PCL) injury, and 1 case of MCL injury with patellar dislocation; there were 38 males and 21 females with an average age of 23.2 years (range, 16-39 years). In the control group, 68 patients had no MCL rupture by MRI, including 38 cases of ACL injury, 4 cases of ACL and PCL injury, and 26 cases of ACL and lateral meniscus injury; there were 45 males and 23 females with an average age of 31.8 years (range, 25-49 years). The "bay sign" was observed under arthroscope in 2 groups before and after operation. The positive "bay sign" was seen under arthroscope in the patients of the observation group before MCL repair; the "bay sign" disappeared after repair. No "bay sign" was seen in patients of the control group before and after ACL reconstruction. The "bay sign" is a reliable diagnostic evidence of MCL injury. It can be used as a basis to judge the success of MCL reconstruction during operation.

Objective: To investigate the value of temporary balloon occlusion of the abdominal aorta in the treatment of complete placenta previa with placenta accreta. Methods: From January 2015 to February 2016, 24 cases of complete placenta previa with placenta accreta were treated with temporary balloon occlusion of the abdominal aorta(the study group)before cesarean, and 24 cases of complete placenta previa with placenta accreta did not receive balloon occlusion(the control group). The operation time, intraoperative blood loss, intraoperative blood transfusion volume, the perioperative hemoglobin level, the hysterectomy rate and the related complications were compared retrospectively.Also, the hospitalization time, the blood coagulation parameters after operation, including activated partial thromboplastin time(APTT), fibrinogen(FIB), D-Dimer and reperfusion injury parameters including creatine phosphokinase(CK), creatine phosphokinase isoenzyme(CK-MB), lactate dehydrogenase(LDH)and serum creatinine were compared between the 2 groups. Results: The blood loss[750 ml(400- 2 000 ml)vs 2 000 ml(1 500- 2 375 ml); Z =-3.214, P =0.001]and blood transfusion volume[200 ml(0-800 ml)vs 800 ml(0-1 200 ml); Z =- 2.173, P =0.030]in the study group were lower than in the control group. The hemoglobin difference between before and after operation in the study group was lower than the control group[(12.8±13.4)g/L vs(22.9±20.1)g/L; t =-2.041, P =0.047]. In the study group, there were still bleeding in 13 cases after releasing the balloon, 5 of them received uterine artery embolization, 5 cases received uterine artery ligation, and 3 cases received uterine packing. One case had venous thrombosis in the right lower limb. Two cases(8%,2/24)in the control group had hysterectomy, while none in the study group, there was no statistical significance( P = 0.489). Conclusions: Temporary balloon occlusion of the abdominal aorta can effectively reduce blood loss and blood transfusion in the treatment of complete placenta previa with placenta accreta, but there is still the risk of continuing bleeding after releasing the balloon. Other methods of hemostasis might be needed.

This study aimed to investigate the effect of counseling on quality of life (QOL) in postmenopausal women conducted in Hamadan, Iran in 2015. In this quasi-experimental study, 80 postmenopausal women were randomly selected and allocated to case and control groups (40 per group). Data collection tool included questionnaires of demographic information and QOL during menopause, which were completed by the samples before the intervention. In the case group, training program was run during four sessions in the form of weekly consulting sessions for 45 to 60 minutes. Training program included familiarity with menopause symptoms, confrontation and self-care during this period. The control group, only received routine cares. Three months after intervention, information were collected in both groups. Data were analyzed using SPSS for Windows. Before the intervention, mean ± standard deviation for QOL in case group was 101.2 ± 31.4 and it was significantly decreased to 96.9 ± 27.0 after intervention ( P < 0.05). While no significant change was observed in the control group (from 98.9 ± 35.5 to 102.3 ± 35.0, P = 0.443). Symptoms of physical ( P = 0.033) and sexual ( P < 0.001) dimensions significantly decreased in the case group. While significant increase was observed in terms of psychosocial ( P = 0.049) and sexual symptoms in control group. Findings suggested impact of consulting on improvement of QOL during menopause. Supportive consulting can be a suitable approach for improving women's health, reducing problems and enhancing QOL in menopause period.

This study aims to evaluate the effectiveness of pre-travel counselling carried out in Travel Clinics. This is a retrospective cohort. Three hundred international travellers were enrolled; 150 people were from users of Bari Travel Clinic, 150 were users of a travel agency. Enrolled subjects were interviewed using a questionnaire. The average age of the enrolled subjects was 37.5 ± 13.9, without statistically significant differences between the two groups. 86% of cases and 19.3% of the controls reported the use of anti-malaria prophylaxis (p < 0.0001). Vaccination against cholera was given to 62% of cases and 7.3% of the controls (p < 0.001). Travel Clinic users, 6% reported diarrhoea and these figures were 27% in the control group (p < 0.0001). The proportion of those interviewed who reported fever (3.7) or insomnia (1.3) did not differ between the two groups. Mosquito bites were reported by 8% of cases and 20% of the controls (p = 0.003). Three cases of malaria were reported among the controls but no cases were detected among the cases (chi-square = 3.03; p = 0.08). Our study demonstrated the effectiveness of pre-travel counselling; in the future, new studies must investigate the cost-effectiveness of pre-travel prevention measures.

Background The long time use of opium has some effects on serums biochemical factors, the determination of this variation is a new approach in understanding off addiction and relive of drug abuser health. Hence in this study, these indicators in person who were withdrawing of opium have been studied. Methods In this cross-sectional study bloods biochemical factors such as fasting blood sugar (FBS), sodium (Na), calcium (Ca), uric acid (UA), blood urea nitrogen (BUN), creatinine, cholesterol, total protein, and fibrinogen in three groups serum were studied: (1) Who had been permanent opium users more than 2 years (case). (2) Dependent person who has taken one month addiction withdrawal course (control). (3) A healthy group that had been demographically similar to the other groups. Findings According to these study findings, FBS serum level in the case group is lower than control group. Serum level of Na, creatinine, and blood triglyceride (TG) in case study are higher than group control. Concentration of potassium, Ca, UA, BUN, cholesterol, total serum protein, fibrinogen, and thrombin time in case study and group control showed no significant difference. Also, in withdrawing case serum level of Na, Ca, UA, BUN, creatinine, and TG significantly increase and thrombin time decrease. Conclusion According to this study not only the longtime use of opium but also opium with drawerin opium dependent people can change their serum biochemical factors. So recognition, treatment, and prevention of this change could be a new step in improving of health and condition of patients. PMID:25984281

To examine the effect of a newly-developed tracheal detecting-bulb (TDB) in preventing the spray of contaminants in patients' exhalent during emergency endotracheal intubation procedure. 62 emergency patients (male or female, age 21-73 years, weight 47-83 kg, with different levels of consciousness and spontaneous breathing) were randomly divided into two groups (n =31 each) to receive endotracheal intubation by an anesthesiologist with more than 17 years of experience, with (TDB group) or without (control group) a TDB connected to the tracheal tubing. Records were taken regarding the patient's coughing, expansion / contraction of the TDB, the operator's feeling of the patient's exhalent on his face / neck and the contamination of these areas by blood / secretions from the patients in the due course. In TDB group, expansion / contraction of TDB occurred in all cases, but the operator felt no exhalent in any of them. In 9 cases the patients coughed but the operator was contaminated only in 2 cases. While in control group, the patients' exhalent was felt in 16 cases. Coughing were recorded in 7 cases, and the operator was contaminated in 11 cases. In comparison with the control group, TDB group had significantly lower(both P < 0.05), incidence in feeling the exhalent (0 vs. 16), and contamination by blood or secretions (2 vs. 11) although the two groups had no significant difference in the incidence of coughing (9 vs. 7, P > 0.05). TDB can play an important role in blocking the spray of contaminants in patients' exhalent during endotracheal intubation.

To examine the effect of case management on glycemic control and behavioral outcomes in adults with Type 2 diabetes in China. Participants were randomly assigned to a 1-year case management (CM) group (n=60) or control group (n=60). Monthly case management visits included identifying individuals' diabetes-related problems, setting goals, planning self-care, and evaluating progress. During a 1-year follow-up, all participants attended visits every 3 months without intervention. In the CM vs. the control group, HbA1c was reduced at 6 months compared to baseline (P=0.034), with trends at 12 and 24 months, and empowerment ability improved (P<0.05). Also in the CM vs. controls, total self-care behaviors, the frequency of exercise, blood glucose testing, and foot care were higher (P<0.001) at 12 months, and the percentage of individuals with HbA1c ≤7.0% was higher (P=0.035) at 24 months. The case management intervention in China was effective at 6 months and, based on trends in HbA1c at 12 and 24 months and results for behavioral outcomes, the intervention shows promise and warrants more research. A case management approach can enhance behavior change and glycemic control in Chinese with diabetes. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To compare the incidence of femoral access puncture site complications in the control group, who underwent 6 hr of bed rest, with patients in the case group, who underwent 4 hr of bed rest. The ideal bed rest length after percutaneous coronary intervention with a 7-French arterial sheath has been investigated by nursing practice. However, in this larger-sheath-size group, best practices have not been determined, and bed rest time continues to vary markedly among institutions. Retrospective study. Data were retrieved from the National Cardiovascular Data Registry and electronic health records in this retrospective study. Sample size was 401 patients: 152 case patients with 4-hr bed rest and 249 controls with 6-hr bed rest. Case group data were obtained from 20 May 2013-31 December 2014; and control group data, 15 June 2011-20 May 2013. National Cardiovascular Data Registry event rates were generally low in both groups: Only three patients in each group had a bleeding event within 72 hr (2% vs. 1%) and no patient and only two controls had arteriovenous fistula (0% vs. 1%). Complications documented in the electronic health records with institutional femoral access puncture site complication definitions identified bleeding at the access site in eight case patients (5%) and nine controls (4%). Haematoma at the access site occurred in 21 case patients (14%) and 25 controls (10%). The practice change of decreasing bed rest from 6-4 hr for patients with 7-French arterial sheaths post-percutaneous coronary intervention was associated with no significant change in femoral access puncture site complications in either National Cardiovascular Data Registry data or institutional electronic health records data. This introduces expanded evidence of safety in decreasing bed rest length in larger (7-French) arterial sheaths post-percutaneous coronary intervention. © 2017 John Wiley & Sons Ltd.

Background The relationship between surgical margin and local recurrence (LR) in osteosarcoma patients with poor responses to chemotherapy is unclear. Moreover, the incidences of LR according to three different resection planes (bone, soft tissue, and perineurovascular) are not commonly known. Methods We evaluated the incidence of LR in three areas. To assess whether there is a role of surgical margin on LR in patients resistant to preoperative chemotherapy, we designed a case (35 patients with LR) and control (70 patients without LR) study. Controls were matched for age, location, initial tumor volume, and tumor volume change during preoperative chemotherapy. Results LR occurred at the soft tissues in 18 cases (51.4%), at the perineurovascular tissues in 11 cases (31.4%), and at the bones in six cases (17.2%). The proportion of inadequate perineurovascular margin was higher in the case group than in the control group (p = 0.01). Within case-control group (105 patients), a correlation between each margin status and LR at corresponding area was found in the bone (p < 0.001) and perineurovascular area (p = 0.001). Conclusions LR is most common in soft tissues. In patients showing similar unfavorable responses to chemotherapy, the losses of perineurovascular fat plane on preoperative magnetic resonance imaging may be a valuable finding in predicting LR.

To compare the role of an aromatase inhibitor (letrozole) with a GnRH agonist (triptorelin) versus case control on the pregnancy rate and recurrence of symptoms and signs in patients with endometriosis. In a prospective randomized clinical trial, after treatment of 144 infertile women in their reproductive age by laparoscopy (whose endometriosis was confirmed by prior laparoscopy), they were divided into 3 groups: group 1 (47 cases) who received letrozole for 2 months, group 2 (40 patients) who were prescribed triptorelin for 2 months and group 3 who were 57 patients in the control group and did not receive any medication. We followed up each group at least for 12 months after their restoration of regular cycle. Pregnancy rate was 23.4% in group 1, 27.5% in group 2, and 28.1% in group 3. The results did not show significant differences among the 3 groups. Recurrence rate of endometriosis was 6.4% in group 1, 5% group 2 and 5.3% in group 3, which was not statistically significantly different as well. Pregnancy rate and endometriosis recurrence rate are comparable among the 3 groups.

To assess the effect of platelet-rich fibrin (PRF) on postoperative pain, swelling, trismus, periodontal healing on the distal aspect of the second molar, and progress of bone regeneration in mandibular third molar extraction sockets. Over a 2-year period, 31 patients (mean age, 26.1 yr) who required surgical extraction of a single impacted third molar and met the inclusion criteria were recruited. After surgical extraction of the third molar, only primary closure was performed in the control group, whereas PRF was placed in the socket followed by primary closure in the case group (16 patients). The outcome variables were pain, swelling, maximum mouth opening, periodontal pocket depth, and bone formation, with a follow-up period of 3 months. Quantitative data are presented as mean. Statistical significance was inferred at a P value less than .05. Pain (P = .017), swelling (P = .022), and interincisal distance (P = .040) were less in the case group compared with the control group on the first postoperative day. Periodontal pocket depth decreased at 3 months postoperatively in the case (P < .001) and control (P = .014) groups, and this decrease was statistically significant. Bone density scores at 3 months postoperatively were higher in the case group than in the control group, but this difference was not statistically important. The application of PRF lessens the severity of immediate postoperative sequelae, decreases preoperative pocket depth, and hastens bone formation.

Osteoarthritis causes severe pain and disability in joints, one of the most prevalent involved joints is the knee joint. There are several therapeutics ways to control pain and disability, but almost none of them are definite treatment. In this article, we tried to reveal the effect of weight loss on improving symptoms of knee osteoarthritis as an effective and permanent therapeutic approach. We chose 62 patients with grade 1-2 (mild to moderate) knee osteoarthritis and divided them equally into case and control groups. Patients should not had used NSAIDs at least for 6 months before study initiation. Symptoms severity was measured by WOMAC and VAS questionnaires before and after 3 months follow up. Weight and BMI were recorded too. Case group was suggested to have weight loss diet of less fat and carbohydrates and control group did not have any limitation. Comparison of variables' average of case and control groups was not logistically meaningful at the initiation and after the end of the study. But there was a meaningful correlation between variables' changes and lifestyle change in both groups, especially in WOMAC and VAS scores. All variables in case group had statistically meaningful differences between their amounts at the beginning and after the end of the study, on the contrary of the control group. In the comparison of our study with similar studies in the world. We deduced that weight loss can improve symptoms of knee osteoarthritis even in short time weight loss diet (3 months).

We examined the association of ABO blood groups with the different types of head and neck cancers. 195 diagnosed cases and 801 controls were selected from a Greek tertiary cancer center. Information regarding type of head and neck cancer and ABO blood group was collected and registered. The O blood group was found to be most prevalent followed by A, B and AB among the controls, whereas blood group A followed by O, B and AB was most prevalent among cancer patients. The difference among the distribution between the cases and controls was statistically significant in blood group A (p<0.05), whereas blood group A had 1.52-fold higher risk of developing head and neck cancer compared to people of other blood groups. Blood group A was found to be a potential risk factor for the development of head and neck cancers.

To investigate the role of anti-human heat shock protein 60 (hHsp60) antibody positivity in the pathogenesis of ectopic pregnancy, following Chlamydia trachomatis (CT) infection. In a case-control study, serological tests for anti-hHsp60 were performed in ectopic pregnancies (study group) and parturients with normal reproductive histories (control group). All participants in both groups were CT IgG(+). hHsp60 IgG(+) prevalences were compared between the two groups, by semiquantitative ELISA. Data were evaluated using nonparametric and parametric tests and multivariable regression. After an initial pilot study, two groups were formed: 63 ectopic gestations (study group) and 95 normal parturients (control group), all CT IgG(+). Blood samples from all cases were tested for anti-hHsp60 IgG. Age, gravidity, and practising contraception were higher in the control group, while a history of pelvic infections were more common in the study group. Hsp60 IgG(+) was found to be significantly higher in the control group (63/95, 66.3%) compared to study group (30/63, 47.6%). Regression analysis revealed anti-hHsp60 positivity was an independent factor delineating the two groups. Immunity to hHsp60 is less common in CT IgG(+) ectopic pregnancies than CT IgG(+) fertile subjects without a history of ectopic pregnancies. Hence, our findings suggest that hHsp60 seropositivity may decrease the probability of an ectopic gestation in subjects with previous CT infections. Copyright © 2018 Elsevier B.V.

This study was carried out on the workers of a lead refinery industry and two control groups in Zanjan city in Iran. The scalp hair samples were collected from 25 workers who were occupationally exposed to lead contamination as a case group and from 25 subjects among the staff of the same industry and 25 subjects among Zanjan citizens as the first and second control groups respectively. A flame atomic absorption spectrophotometer used to determine lead level in all of the samples. The age of all subjects in the three groups was matched. The mean concentrations of hair lead in the workers (case group), the staff (control groupA) and the citizens (control group B) were 131.7±93.4 µgr/gr, 21.1±13.2 µgr/gr and 27.9±14.1 µgr/gr respectively. The mean concentration of hair lead in the case group was more than hair lead of normal range found in humans (0-30 µgr/gr). The mean of hair lead level in the citizens who had used gas vehicles was statistically higher than who had not used it (36.9±12.2 µgr/gr vs. 16.6±4.9 µgr/gr, P<0.001). PMID:21957365

It is difficult to construct a control group for trials of adjuvant therapy (Rx) of prostate cancer after radical prostatectomy (RP) due to ethical issues and patient acceptance. We utilized 8 curve-fitting models to estimate the time to 60%, 65%, … 95% chance of progression free survival (PFS) based on the data derived from Kattan post-RP nomogram. The 8 models were systematically applied to a training set of 153 post-RP cases without adjuvant Rx to develop 8 subsets of cases (reference case sets) whose observed PFS times were most accurately predicted by each model. To prepare a virtual control group for a single-arm adjuvant Rx trial, we first select the optimal model for the trial cases based on the minimum weighted Euclidean distance between the trial case set and the reference case set in terms of clinical features, and then compare the virtual PFS times calculated by the optimum model with the observed PFSs of the trial cases by the logrank test. The method was validated using an independent dataset of 155 post-RP patients without adjuvant Rx. We then applied the method to patients on a Phase II trial of adjuvant chemo-hormonal Rx post RP, which indicated that the adjuvant Rx is highly effective in prolonging PFS after RP in patients at high risk for prostate cancer recurrence. The method can accurately generate control groups for single-arm, post-RP adjuvant Rx trials for prostate cancer, facilitating development of new therapeutic strategies. PMID:24465467

Few studies have looked at lung cancer in prisoners, despite this population is possibly at increased risk of malignancy. In a previous study, we found an early onset of lung cancer in prisoners. Thus, the present CARCAN study was aimed at assessing the epidemiological characteristics, management, prognosis, and incidence of lung cancer in prisoners compared to a sample of non-prisoner patients. We performed a multi-center observational case-control study. Cases were prisoners diagnosed with lung cancer from 2005 to 2013. Controls were non-prisoner lung cancer patients selected from hospital databases and randomly matched to cases (targeted case-control ratio: 1:3). Incidence rates in both groups were calculated using national statistics. Seventy-two cases and 170 controls met inclusion criteria. Cases were mainly men (99%). Mean age at diagnosis was 52.9 (± 11.0) in cases and 64.3 (± 10.1) in controls (p < 0.0001). More case patients were current smokers compared to control patients (83% vs 53%; p < 0.0001). We found no significant differences between the two groups as concerns histologic types, TNM stages at diagnosis, initially-employed treatments, times to management or survival. Incidence rates (2008-2012) in male prisoners were higher than those in the general population in all concerned age groups. There is a shift of lung cancer toward young people in prisons. However, the presentation, management, and prognosis of lung cancer are similar between prisoners and non-prisoners. These finding could justify a specific screening policy for the incarcerated populations.

To investigate the risk factors, clinical prediction and intrapartum management of shoulder dystocia in non-macrosomia. Totally 7 811 cases of vaginal delivery were retrospectively reviewed from Juanary 2009 to December 2013 in Shengjing Hospital. Shoulder dystocia was found in 11 cases (0.14% , 11/7 811), including 1 case of macrosomia and 10 cases of non-macrosomia (shoulder dystocia group). Each non-macrosomia shoulder dystocia case was matched with 10 cases of normal delivery in the same week, which were selected randomly as the control group. The tendency and risk factors of shoulder dystocia in macrosomia and non-macrosomia were analyzed, and the following data between the two groups were compared, including the height of uterus fundus, abdominal circumference of the pregnant woman, the increasing of body mass index (BMI), fetal biparietal diameter (BPD), fetal femur length (FL), duration of every stage of labor, birth weight of the newborn, head circumference and chest circumference of the newborn, Apgar score. (1) There were 213 macrosomias among the 7 811 vaginal deliveries, with the incidence of 2.73% (213/7 811). Only 1 shoulder dystocia was macrosomia (0.46%, 1/213); while the other 10 cases were non-macrosomia ( 0.13%, 10/7 598). (2) From 2009 to 2013, the macrosomia happened by 24 cases (2.32%, 24/1 034), 42 cases (3.61%, 42/1 164), 46 cases (2.60%, 46/1 772), 62 cases (3.01%, 62/2 060), 39 cases (2.19%, 39/1781), respectively. The incidence of macrosomia had no significant difference among these 5 years (P > 0.05). The shoulder dystosia occurrence without macrosia in these 5 years were 1 case ( 0.10% , 1/1 034), 3 cases (0.26%, 3/1 164), 2 cases ( 0.11%, 2/1 172), 2 cases (0.10%, 2/2 060), 2 cases ( 0.11%, 1/1 781), respectively. The incidence of shoulder dystocia without macrosomia had no significant difference among these 5 years (P > 0.05). (3) In the should dystocia group, 5 cases were complicated with premature rupture of membrane (5/10), 4 cases were mother≥ 35 years old (4/10), 3 cases were multipara(3/10), 3 cases had gestational diabetes mellitus(3/10), 3 cases were occiput posterior during the first stage of labor (3/10), 3 cases had prolonged second stage of labor (3/10) and 6 cases had routine lateral incision (6/10). In the control group, 3 cases were complicated with premature rupture of membrane(3/10); 1 case was mother≥35 years old (1/10); 2 cases were multipara(2/10), 3 cases had gestational diabetes mellitus (3/10), 1 case had prolonged second stage (1/10) and 7 cases had routine lateral incision (7/10). (4) There were no significant difference in the height of uterus fundus, BMI, BPD, FL, and duration of the first stage of labor between the shoulder dystocia group and the control group (P > 0.05). Compared with the control group, the increasing of BMI [(6.8±3.1) vs (4.8±1.4) kg/m(2)], the time of the second stage of labor[(86±65) vs (38±28) minutes ] and abdominal circumference[(108±8) vs (101±7) cm] were significantly higher in the shoulder dystosia group (P < 0.05). (5) There were significant difference in the chest circumference of the newborn [(34.0±1.6) vs (32.2±1.9) cm ] and the ratio of chest circumference to head circumference of the newborn [(0.99±0.03) vs (0.97±0.03) ] between the two groups (P < 0.05). The 1-minute Apgar score of the newborn (7.4±2.8) was significantly lower than the control group (10.0±0.0) (P < 0.01). Clavicular fracture occurred in 3 newborns and brachial plexus injury occurred in 4 newborns in the shoulder dystosia group. It is difficult to predict shoulder dystocia in non-macrosomia. Shoulder dystocia of non-macrosomia could be predicted by measurement of the head circumference, chest circumference, the ratio of chest circumference to head circumference by using prenatal ultrasound. The risk factors may complicated with premature rupture of membrane, abnormal occiput position during the first stage of labor and prolonged second stage of labor.

The aim of this study is to investigate if neutrophil CD64 expression in febrile neutropenia patients could be used as an early indicator of bacteremia. All consecutive patients older than 18 years of age who had developed febrile neutropenia episodes due to hematological malignancies were included in the study. Those patients who had significant growth in their blood cultures constituted the case group, while those who had febrile neutropenia without any growth in their cultures and who did not have any documented infections formed the control group. Blood culture bottles were incubated in the Bact ALERT 3D system (bioMerieux, France), identification and susceptibility testing were performed using an automated broth microdilution method (VITEK 2, bioMerieux), and CD64 expression analysis was performed by the flow cytometry method. C-reactive protein (CRP) was measured by turbidimetric methods (Biosystems, Spain) and erythrocyte sedimentation rate (ESR) was measured by the Wintrobe method. In total, we prospectively evaluated 31 febrile episodes. The case group consisted of 17 patients while the control group included 14 patients. CD64 was found on neutrophils of the case group patients with a mean count of 8006 molecules/cell and of control group with a mean count of 2786 molecules/cell. CD64 levels of the case group were significantly higher than those of the control group (p=0.005). In the differentiation of the case group from the control group, a 2500 cut-off value for CD64 had significant [AUC=0.792 (0.619-0.965)] predictive value (p=0.001). In the prediction of patients with a 2500 cut-off value for CD64, sensitivity was 94.1%, positive predictive value was 76.2%, specificity was 64.3%, and negative predictive value was 90.0%. CRP levels and ESR values did not differ significantly between the groups (p=0.005). Neutrophil CD64 expression could be a good predictor as an immune parameter with high sensitivity and a negative predictive value for bacteremia in febrile neutropenic patients.

The study aims to explore the roles of common polymorphisms of Tumor Necrosis Factor-α (TNF-α) (-238 A/G and -308 A/G) and IL-10 (-819 T/C and -1082 G/A) genes in the risk of non-traumatic osteonecrosis of the femoral head (NONFH). One hundred and forty-seven NONFH patients and 135 healthy individuals were selected as the case and control groups. qRT-PCR and Western blotting techniques detected mRNA as well as protein expressions of TNF-α and IL-10 of each genotype in both the case and control groups. The GA genotype and the A allele of TNF-α -238 A/G were higher in the case group than in the control group. Compared with the control group, AA, GA, and AG + AA genotypes as well as the A allele of IL-10-1082 G/A were all lower in the case group. In the case groups increased levels of TNF-α as well as decreased levels of IL-10 expression when compared with the control group. TNF-α expression of TNF-α-238 GA genotype was significantly higher than that in patients with GG genotype, while the IL-10 expression of GA and AA genotypes of IL-10-1082 was significantly lower than in that of patients with the GG genotype. TNF-α protein expression in the GA genotype was significantly higher than in the GG genotype. In relation to TNF-α -238, TNF-α protein expression of GA and AA genotypes had significantly reduced more so than the GG genotype in IL-10-1082. TNF-α-238 A/G and IL-10-1082 G/A may be involved as risk factors of NONFH. J. Cell. Biochem. 118: 4872-4880, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

The Central Nervous System (CNS) lesions show considerable geographic and racial variations with respect to the incidence and the pattern of distribution of lesions. The ABO blood status is a readily accessible factor in genetic constitution of the patients. It has been shown to be associated with many diseases. But the influence of blood group status on the pathogenesis of brain tumours is still unclear. To study various histopathological patterns of CNS lesions and to evaluate the association of CNS tumours with the distribution of ABO blood groups in documented cases. In the present study, 147 cases were analyzed. It was an analytical type of study, done at JSS Medical College, Mysore, over a period of 2 years and 8 months from January 2009 to August 2011. Histopathology slides were routinely stained by Haematoxylin and Eosin (H&E) stain. Special stains were performed in selected cases. Blood group of the patients and the control group were documented. Blood group distribution pattern was assessed in relation to histopathological diagnosis of various CNS tumours. Histopathological diagnosis of 147 cases included neoplastic lesions (84.35%) and non-neoplastic lesions (15.64%). Neoplastic lesions (84.35%) constituted the majority, which included neuroepithelial tumours (29.25%) as predominant pattern. Non-neoplastic lesions constituted only 15.64%, which included inflammatory lesion (8.16%) as the predominant pattern. ABO blood group data was available in 92 cases (84.4%) of neoplastic lesions, which included 71 cases (48.29%) of primary CNS neoplasms categorized according to WHO grades. The control group constituted 21,067 healthy voluntary donors. Blood group O was the most frequent blood group in neoplastic lesions (40.21%) and primary CNS neoplasms categorized according to WHO grades (45.07%). The association between the CNS neoplasms and ABO blood groups was not statistically significant (p = 0.055). But a definite change in the pattern of distribution of ABO blood groups observed between neoplastic lesions and control groups. The influence of blood group types on the development of brain tumours appears intriguing and needs to be well established. Though statistically insignificant, a definite change in the pattern of distribution of ABO blood groups was observed between neoplastic lesions and control groups. This necessitates attention and stratification of patients for effective management.

A full range of motion after total knee arthroplasty has become more and more requested by our patients, leading to novel designs of knee implants, the so-called "hyperflex" knees. The aim of the present study was to confirm whether or not hyperflexion of operated knees really improves the patients' quality of life. A retrospective comparative case-control study has been carried out to compare clinical results shown in two types of knee prosthesis, from two homogeneous paired groups of patients including 45 cases of a "hyperflex" model (RP-F), while the control group consisted of 43 cases of a "regular design" model (Triathlon) in terms of expected postoperative flexion. The hyperflex group demonstrated significant higher mean values of passive flexion at 119.9° in the RP-F group versus 111.1° in the Triathlon group. However, global results in the "regular" control group were significantly better than the "hyperflex" study group, in both IKS knee and functional scores at 84.4 points (RP-F) vs. 89.8 points (Triathlon), and 84.6 points (RP-F) vs. 89.5 points (Triathlon), respectively. Moreover, the self-administered KOOS questionnaire was significantly in favor of the control group, with 73.5 points in RP-F knees versus 86.0 points for Triathlon knees at global KOOS postoperative scores. The quality of life of operated patients after TKA obviously would be considered as the main priority, which was better obtained by a "regular design" in our study. Hence "high flexion" cannot be considered as an absolute target when choosing a model for total knee arthroplasty.

This study is to estimate the effectiveness of a diabetic case management programme on health-care service utilization. The study population included 6007 as the intervention group and 956,766 as the control group. As the indicators of health-care service utilization, numbers of medical ambulatory consultations, days of medication prescribed and medical expenses for one year were used, and we analysed the claim data of the health insurance from 2005 to 2007. The study population was classified into three subgroups based on the number of medical ambulatory consultations per year before this intervention. In the under-serviced subgroup, the intervention group showed a significant increase in the number of consultations (3.2), days of prescribed medication (66.4) and medical expenses (287,900 KRW) compared with the control group. Conversely, in the over-serviced subgroup, the intervention group showed a less decrease days of prescribed medication (1.6) compared with the control group. This showed that the case management programme led the intervention group to optimize their utilization of health-care services by subgroups. It is necessary to evaluate the appropriateness of health-care usage and clinical outcome to show the direct effectiveness of the case management programme by subgroups. © 2014 Wiley Publishing Asia Pty Ltd.

Investigate the effectiveness of health education programs by using the PRECEDE-PROCEED Model to improve non-Thai migrant TB patient's compliance during treatment. This quasi-intervention study was conducted in three targeted hospitals, between August 2009 and December 2010. The study sample consisted of 100 cases, 50 cases who registered in Samutsakorn Province served as the intervention group and 50 cases who registered in Samutprakarn Province served as the control group. At the end of the health education intervention, the intervention group showedsignificantly improved health-behavior scores in nine domains-health promotion, health education, predisposing, reinforcing, enabling factors, behavior and lifestyle, environment, and health status, which were also significantly higher than the control group (p < 0.001). The percentage of patients achieving successful treatment outcomes was 76% in the intervention group and 62% in the control group. The tuberculosis treatment and care program, and the associated health education interventions enabled migrants to complete the treatment regimen and achieve treatment success. It could also help TB staff develop an appropriate program and clear understanding of TB control among migrants. It is recommended that this type of information and health education program be used in other hospitals and healthcare settings providing TB services for migrants throughout the nation.

Iron deficiency anemia (IDA) is one of the most common nutritional disorders in the world. In the present study, we evaluated erythrocyte membrane fatty acid composition in premenopausal patients with IDA. Blood samples of 102 premenopausal women and 88 healthy control subjects were collected. After the erythrocytes were separated from the blood samples, the membrane lipids were carefully extracted, and the various membrane fatty acids were measured by gas chromatography (GC). Statistical analyses were performed with the SPSS software program. We used blood ferritin concentration <15 ng/mL as cut-off for the diagnosis of IDA. The five most abundant individual fatty acids obtained were palmitic acid (16:0), oleic acid (18:1, n-9c), linoleic acid (18:2, n-6c), stearic acid (18:0), and erucic acid (C22:1, n-9c). These compounds constituted about 87% of the total membrane fatty acids in patients with IDA, and 79% of the total membrane fatty acids in the control group. Compared with control subjects, case patients had higher percentages of palmitic acid (29.9% case versus 25.3% control), oleic acid (16.8% case versus 15.1% control), and stearic acid (13.5% case versus 10.5% control), and lower percentages of erucic acid (11.5% case versus 13.6% control) and linoleic acid (15.2% case versus 15.4% control) in their erythrocyte membranes. In conclusion, the total-erythrocyte-membrane saturated fatty acid (SFA) composition in premenopausal women with IDA was found to be higher than that in the control group; however, the total-erythrocyte-membrane unsaturated fatty acid (UFA) composition in premenopausal women with IDA was found to be lower than that in the control group. The differences in these values were statistically significant.

Recruitment of controls remains a challenge in case-control studies and particularly in studies involving minority populations. We compared characteristics of controls recruited through random digit dialing (RDD) to those of community controls enrolled through churches, health events and other outreach sources among women of African ancestry (AA) participating in the Women's Circle of Health Study, a case-control study of breast cancer. Odds ratios and 95% confidence intervals were also computed using unconditional logistic regression to evaluate the impact of including the community controls for selected variables relevant to breast cancer and for which there were significant differences in distribution between the two control groups. Compared to community controls (n=347), RDD controls (n=207) had more years of education and higher income, lower body mass index, were more likely to have private insurance, and less likely to be single. While the percentage of nulliparous women in the two groups was similar, community controls tended to have more children, have their first child at a younger age, and were less likely to breastfeed their children. Dietary intake was similar in the two groups. Compared to census data, the combination of RDD and community controls seems to be more representative of the general population than RDD controls alone. Furthermore, the inclusion of the community group had little impact on the magnitude of risk estimates for most variables, while enhancing statistical power. Community-based recruitment was found to be an efficient and feasible method to recruit AA controls.
[The case-case-time-control study design].

Although the 'self-matched case-only studies' (such as the case-cross-over or self-controlled case-series method) can control the time-invariant confounders (measured or unmeasured) through design of the study, however, they can not control those confounders that vary with time. A bidirectional case-crossover design can be used to adjust the exposure-time trends. In the areas of pharmaco-epidemiology, illness often influence the future use of medications, making a bidirectional study design problematic. Suissa's case-time-control design combines the case-crossover and the case-control design which could adjust for exposure-trend bias, but the control group may reintroduce selection bias, if the matching does not go well. We propose a "case-case-time-control" design which is an extension of the case-time-control design. However, rather than using a sample of external controls, we choose those future cases as controls for current cases to counter the bias that arising from temporal trends caused by exposure to the target of interest. In the end of this article we will discuss the strength and limitations of this design based on an applied example.

To evaluation the clinical effect of combination of traditional Chinese medicine and western medicine on Bell's palsy. 83 patients with Bell's palsy were randomly divided into two groups (trail group 54 cases and control group 29 cases). Patients in two groups were treated with medicine, acupuncture, physiotherapy, while patients in the trail group were treated with massage and functional exercise as the same time. The results of both groups were evaluated according to Portmann's Simple Scale. The score before treatment of trail group was 2.907 +/- 1.794, while control group was 2.931 +/- 2.034. And the score after treatment of trail group was 18.593 +/- 1.743, while control group was 9.862 +/- 3.091. Score of the function of facial muscles obtained from trail group was distinctly higher than that was from the control group (P < 0.01), as well as the improvement index (P < 0.01, trail group: 0.844 +/- 0.095, control group: 0.712 +/- 0.129). There is significant curative effect and suitability in the treatment of Bell's palsy with combination of traditional Chinese medicine and western medicine. The improvement of facial muscles' motive function pre- and post-treatment and quantitative evaluation of curative effect can be objectively obtained by evaluation of facial muscles' function.

We analyzed histopathological features in 70 treatment-naïve children: 10 with HBV/HCV coinfection (case group A), 30 with HBV (control group B), and 30 with HCV (control group C). Liver biopsies were scored for grading and staging according to Knodell's modified system and were tested for an association with demographic and laboratory data. The mean grade was higher in coinfected children compared to control group C (6.2 ± 3.0 vs. 4.2 ± 2.5, p = 0.04), but not control group B (p = 0.47). A higher proportion of patients with moderate to severe necroinflammation were observed in case group A compared to isolated HCV (p = 0.05). Mean staging did not differ between the case and control groups. Multivariate analysis revealed that HBV/HCV coinfection and aminotransferase activity were independently associated with moderate to severe necroinflammatory activity Conclusion: HBV/HCV coinfection was associated with moderate to severe necroinflammation irrespective of age at biopsy or duration of infection and led to significantly higher necroinflammatory activity than HCV monoinfection. HBV/HCV coinfection did not enhance fibrosis. High aminotransferase levels were positively associated with moderate to severe necroinflammation.

Little is known about herpesvirus and putative periodontopathic bacteria in maternal chronic periodontitis. The present case-control study aimed to explore the potential relationship between putative periodontopathic bacteria and herpesviruses in maternal chronic periodontitis.Saliva samples were collected from 36 pregnant women with chronic periodontitis (cases) and 36 pregnant women with healthy periodontal status (controls). Six putative periodontopathic bacteria (Porphyromonas gingivalis [Pg], Aggregatibacer actinomycetemcomitans [Aa], Fusobacterium nucleatum [Fn], Prevotella intermedia [Pi], Tannerella forsythia [Tf], and Treponema denticola [Td]) and three herpesviruses (Epstein-Barr virus [EBV], human cytomegalovirus [HCMV], and herpes simplex virus [HSV]) were detected. Socio-demographic data and oral health related behaviors, and salivary estradiol and progesterone levels were also collected. The results showed no significant differences in socio-demographic background, oral health related behaviors, and salivary estradiol and progesterone levels between the two groups (all P > 0.05). The detection rates of included periodontopathic microorganisms were not significantly different between the two groups (all P > 0.05), but the coinfection rate of EBV and Pg was significantly higher in the case group than in the control group (P = 0.028). EBV and Pg coinfection may promote the development of chronic periodontitis among pregnant women. PMID:27301874

The population of gynaecological cancer survivors is growing, yet little is known about the effects of cancer and treatment on socioeconomic conditions well beyond the completion of therapy. The aim of this study was to investigate the socioeconomic conditions in long-term survivors of gynaecological cancer compared with a representative group of women from the general population. The study comprises women aged 32-75 residing in central part of Norway and who were treated as primary cases of gynaecological cancer at the University Hospital in Trondheim, Norway (n=160), and a control group from the general population (n=493). All analyses were done by chi(2) test and logistic regression. Gynaecological cancer survivors scored lower on a Socioeconomic Condition Index than the control group. They had on the average a complete remission period of 12 years. Compared with the control group, they were more often disabled (p<0.01) and had lower annual household income (p<0.01). No difference was detected between the groups in ability to pay bills. More cases than controls had experienced problems assigning personal insurance (p<0.03). Long-term gynaecological cancer survivors lived under poorer socioeconomic conditions, were more often disabled and had lower annual household income than the women in the control group, whereas no difference in ability to pay bills were found between the groups. In spite of poorer socioeconomic conditions, the gynaecological cancer survivors seem to adapt well to their financial situation.

Infantile colic is a common problem among young infants. Cow's milk allergy has been suggested as one of the causes. We aimed to investigate the value of the cow's milk skin test for the diagnosis of cow's milk allergy in exclusively breast-fed infants with infantile colic. Exclusively breast-fed infants with infantile colic were enrolled in this study. On the first visit, the average hours of crying of the infant in a 24-h period were recorded and the cow's milk skin test was performed. If the infant had a positive skin test, elimination of cow's milk from the mothers' diet was advised. Infants with negative skin tests were divided into case and control groups. Cow's milk was eliminated from the diet of mothers in the case group. After 2 weeks, the number of hours of crying were recorded again. The reduction in the crying hours was compared between the two groups using the chi-square test. Skin tests were positive in 3 of 114 cases (2.6%) of infantile colic. All three cases recovered completely following elimination of cow's milk from the mother's diet. Among the 111 patients with negative skin tests, 77 patients completed the study: 35 in the case group and 42 in the control group. The reduction in crying hours in infants in the case group was not significantly different from that in the control group. Elimination of cow's milk from the mothers' diet is not beneficial for infants with a negative skin test. Infants with a positive skin test may benefit from this management.

The aim of this study was to explore the cytomorphometric and morphological effects of Trichomonas vaginalis in exfoliated epithelial cells. Ninety-six Pap-stained cervical smears were divided into a study group and two control groups as follows: T. vaginalis cases, a first control group with inflammation, and a second control group without inflammation. Micronucleated, binucleated, karyorrhectic, karyolytic, and karyopyknotic cells and cells with perinuclear halos per 1,000 epithelial cells were counted. Nuclear and cellular areas were evaluated in 70 clearly defined cells in each smear using image analysis. The frequencies of morphological parameters in the T. vaginalis cases were higher than the values of the two control groups, and the difference among groups was found to be significant (p < 0.05). The nuclear and cytoplasmic areas of epithelial cells were diminished in patients with trichomoniasis. The mean nucleus/cytoplasm ratio in T. vaginalis patients was higher than the value in the control groups, and the difference between the study group and control group 1 was significant. However, there was no statistically significant increase between the study group and control group 2. T. vaginalis exhibited significant changes in the cellular size and nuclear structure of the cells. The rising frequency of micronuclei, nuclear abnormalities, and changing nucleus/cytoplasm ratio may reflect genotoxic damage in trichomoniasis. © 2015 S. Karger AG, Basel.

When cases of dental crowding are identified and diagnosed promptly, interceptive orthodontics is particularly successful. Aim: To assess the differences in the eruption sequence of the mandibular canine and first premolar teeth in children with and without dental crowding. Materials and Methods: Children who attended the Shiraz Dental School's orthodontic clinic (Iran) from September to December 2012 were enrolled in this case-control study. Tooth size arch length discrepancy (TSALD) of all 8-10 year olds was calculated from patients’ dental models. Thirty-six children were randomly selected from those with TSALD of equal or less than 4mm (those with crowding). Each selected case was matched for sex and age with another child (as control) with TSALD>−4mm attending the same clinic, in the same time period. The existing panoramic radiographs were traced and the eruption percentages were measured for mandibular canine and first premolar teeth. The mean difference between canine and first premolar eruption percentages was compared between the case and control groups using the SPSS (version PASW 18) software and a paired sample t-test. Results: Canine and first premolar eruption percentages in the case group were 65.82±13.00 and 78.92±10.15 percent, respectively. The mean eruption percentages for canines and first premolars of the control group were 74.12±14.55 and 75.47±11.60 percent, respectively. There was a significant difference in pre-eruptive positions of canine and first premolar teeth in those with moderate to severe crowding when compared to the control group (p<0.001). Conclusion: These findings may improve the early diagnosis of children with high risk of developing moderate to severe crowding during mixed dentition. PMID:25110582

This study aimed at evaluating possible association between MDM2 SNP309 polymorphism (rs 2279744) and polycystic ovary syndrome (PCOS). One hundred and twenty-five women with PCOS and two hundred and fifty women without PCOS were collected from the department of reproductive medicine of college hospital in this case-control study. Peripheral blood samples were collected from all participants and DNA was extracted, MDM2 SNP309 polymorphism (rs 2279744) was determined from the 125 cases and 250 controls. Women were grouped into PCOS (n = 125) group and control group (n = 250). Odds ratios (OR) and 95% confidence intervals (CI) were used to evaluate the association between MDM2 SNP309 polymorphism (rs 2279744) and PCOS. The distribution of T allele was significant higher in PCOS cases than controls. MDM2 SNP 309 T allele is associated with PCOS.

This study evaluates the effect of a care management service (CMS) on falls in older adults. This is a retrospective case-control study with 78 CMS recipients as the case group who received CMS and another 312 community-dwelling frail elders as the control group.The groups were matched by age, gender, activity of daily living, cognitive impairment, and unsteady gait. Thus they were comparable in characteristics and frailty. Among the 390 participants, 89 older adults (23.0%) had falls in the 90 days prior to the survey. After controlling for the identified risk factors for falls, the odds ratio of CMS was 0.27 (95% confidence interval = 0.110-0.663, p < .01). These findings indicate that CMS recipients have a lower chance for falls compared to their counterparts. The two features of CMS (comprehensive assessment and multidisciplinary actions to reduce fall risks) are discussed.

Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we summarize the recommendations of that group regarding best practices for planning, design and enrollment of cases and controls. Rigorous planning and preparation should focus on understanding the study context including healthcare-seeking and vaccination practices. Case-control vaccine effectiveness studies are best carried out soon after vaccine introduction because high coverage creates strong potential for confounding. Endpoints specific to the vaccine target are preferable to non-specific clinical syndromes since the proportion of non-specific outcomes preventable through vaccination may vary over time and place, leading to potentially confusing results. Controls should be representative of the source population from which cases arise, and are generally recruited from the community or health facilities where cases are enrolled. Matching of controls to cases for potential confounding factors is commonly used, although should be reserved for a limited number of key variables believed to be linked to both vaccination and disease. Case-control vaccine effectiveness studies can provide information useful to guide policy decisions and vaccine development, however rigorous preparation and design is essential.

Objective: To evaluate the efficacy and safety of Saccharomyces boulardii in the prevention of antibiotic-associated diarrhea (AAD) in infants and young children. Method: From November 2012 to September 2013, ten research units of large teaching hospitals or children's hospitals participated in this multicenter randomized controlled clinical trial. Hospitalized young children aged between 1 month and 3 years (nongastrointestinal infection and antibiotic therapy required)were involved in our study. The children were randomly divided into control group and prevention group by means of block random allocation method. The control group received antibiotic therapy and other conventional treatment. The prevention group was given additional Saccharomyces boulardii (250 mg/d) orally. Diarrhea rates of two groups were compared both during the usage of antibiotics and within 14 days after the antibiotics withdrawal. The adverse reactions of Saccharomyces boulardii were observed all through this study. The results were analyzed by χ(2) test or Kruskal-Wallis test or t test. Result: Totally 408 cases (213 cases in prevention group and 195 cases in control group) were enrolled. The age ranged from 1 month to 3 years, with an average age of 1.14 years. The basic diseases were parenteral infections: 368 cases with different kinds of respiratory tract infections or pneumonia, 10 cases of bacterial meningitis, 9 cases with septicemia or sepsis, 6 cases with pertussis or pertussis like syndrome, 5 cases with urinary infection, 5 cases with skin or subcutaneous tissue infections, 3 cases of Kawasaki disease, one with scarlet fever and one with congenital syphilis. During the administration of antibiotics, the incidence of AAD in prevention group was 10.3% (22 cases), which was significantly lower than that of control group (57 cases, 29.2%, χ(2)=23.296, P <0.05). Within 14 days after the discontinuation of antibiotics, the percent of new diarrhea cases in prevention group (2.4%, 5/213) was also significantly lower than that in control group (16.4%, 32/195, χ(2)=23.4, P <0.05). Further analysis revealed that the rate of AAD in children less than or equal to 1 year old (25.1%, 52/207) was significantly higher than that of over 1 year old (13.4%, 27/201, χ(2)=8.922, P <0.05). The incidence of AAD in children treated with antibiotics for more than 5 days was 22.2%(60/270), which was significantly higher than that of less than or equal to 5 days (13.8%, 19/138, χ(2)=4.180, P <0.05). Although no significant difference was observed, the AAD rate of patients with combined use of two antibiotics was higher than that of using one. During the antibiotic therapy, compared with the control group, the risk of AAD in children under 1 year old was reduced by 52% (χ(2)=9.217, P <0.05), and 91% (χ(2)=20.35, P <0.05) in the children over 1 year old in prevention group. The risk of AAD of prevention group decreased by 66% (χ(2)=13.67, P <0.05) in patients treated with one antibiotics, and 65% in children with combined use of antibiotics (χ(2)=10.57, P <0.05). In patients treated with antibiotics for less than or equal to 5 days, the risk of AAD decreased by 74% in prevention group (χ(2)=7.38, P <0.05); and 63% if the course lasted for over 5 days (χ(2)=16.87, P <0.05). Within 14 days after the withdrawal of antibiotics, compared with the control group, the risk of diarrhea in the prevention group decreased by 82% (χ(2)=13.35, P <0.05) in infants (≤1 year old) and 93% (χ(2)=12.00, P <0.05) in children (>1 year old); the risk of diarrhea was reduced by 86% (χ(2)=9.57, P <0.05) and 87% (χ(2)=17.71, P <0.05) respectively in prevention group with single and combined use of antibiotics. In patients treated with antibiotics for more than 5 days, the risk of diarrhea in prevention group was reduced by 63% (χ(2)=22.79, P <0.05), while there was no significant difference if the antibiotics course was less than or equal to 5 days (χ(2)=2.97, P >0.05). No adverse effects related with Saccharomyces boulardii were observed in our study. Conclusion: Saccharomyces boulardii is effective and safe to prevent AAD of infants and young children both during the usage of antibiotics and up to 14 days after drug discontinuance. It can be one of the drugs of for choice prevention of AAD in infants and young children. Trial registration Chinese Clinical Trial Tegister, ChiECRCT-2012-25.

To explore effective interventions for child accidental injury prevention and to reduce the incidence of injury. Cluster random sampling method was adopted, and children in 19 kindergartens in Henggang, Shenzhen and their parents were selected as the objects of study. Nineteen kindergartens were randomly divided into intervention group and control group to carry out the injury intervention case-control study. Through a series of interventions, there were certain effects. After the end of the project, the injury incidence rates of the intervention group and the control group were 4.91%, 10.64%, and the difference was significant; the average costs of treatment for injuries of the intervention group and the control group were 168.4 Yuan and 206.8 Yuan, and the difference was statistically significant; compared with before the implementation of the project, the rate of various types of injuries after the end of the project declined, in which, the rate of mechanical injury, pet bites, accidental falls, burns, and traffic accidents decreased significantly. The differences were significant. Injury interventions can effectively prevent and control the occurrence of injury.

One of the forms of violence that receives less attention due to cultural and social issues is sexual violence against women, which is a hidden and a constant epidemic and impact on their health. This study aimed to determine the relationship between function and sexual satisfaction in women who have experienced sexual violence in Ahvaz-Iran. This study was a case-control study which was conducted on 105 women (cases=35 and control=70) referred to one forensic center and seventeen Shahrivar health centers during 2013-2014 in Ahwaz-Iran. The data collection tools included questionnaires for evaluating demographic characteristics and sexual satisfaction, sexual female function index and sexual violence. The data were analyzed using descriptive and inferential statistics (Chi-square, Fisher's exact, and independent-samples t-test) in SPSS, version 19. P-value < 0.05 was considered significant. Two groups of women were matched according to age and education. Mean ± SD sexual satisfaction was (71.4±15.84) in the case group and (99.44±15.68) in the control group (p<0.001). The mean ± SD of sexual function was (17.1±4.94) in the case group and (26.37±5.27) in the control group. The groups had a statistically significant difference in terms of sexual arousal, sexual orgasm, sexual lubrication, pain and sexual satisfaction (p<0.001). Sexual dysfunction and dissatisfaction have a relation with sexual violence, and a major concern is that the sexual violence in most cases is hidden and can seriously affect the general health condition of women.

This study aims to study the efficacy of simultaneous endoscopic bladder neck incision (BNI) and primary endoscopic valve incision (PEVI) in patients with posterior urethral valves (PUV). Nine PUV patients underwent PEVI and BNI over a year. They were compared to nine comparable historical controls that had undergone only PEVI. Trends in renal function tests, urodynamics and changes in the upper urinary tracts were evaluated after 3 months during which no pharmacotherapy was given. The incidence of bladder dysfunction in the two groups was similar-55.5 % in case group and 66.6 % in control group. Hypocompliant, high-pressure bladder was the predominant cystometric finding in both groups. Three patients in the case group and two patients in the control group had high end infusion pressure (EIP) with poor compliance. Detrusor overactivity (DOA) was seen in 23.1 % patients in the case group as compared to 55.5 % patients in the control group (P = 0.3348). Five patients in both groups were later started on anticholinergics due to raised EIP, small capacity bladder and/or DOA. Although BNI should theoretically improve the outcome of PUV patients, the current pilot study failed to demonstrate any significant difference. A larger sample size and longer follow-up are required to prove or disprove its efficacy.

To evaluate the characteristics of postoperative refractive status in age-related cataract patients with shallow anterior chamber and the correlation between pre-operative anterior chamber depth and postoperative refractive status. Prospective case-control study. Sixty-eight cases (90 eyes) with age-related cataract were recruited from October 2010 to January 2012 in People's Hospital Peking University including 28 cases (34 eyes) in control group and 40 cases (56 eyes) in shallow anterior chamber group according to anterior chamber depth (ACD) measured by Pentacam system. Axial length and keratometer were measured by IOL Master and intraocular lens power was calculated using SRK/T formula. Postoperative refraction, ACD and comprehensive eye examination were performed at 1 month and 3 months after cataract surgery. Using SPSS13.0 software to establish a database, the two groups were compared with independent samples t-test and correlation analysis were performed with binary logical regression. The postoperative refractive deviation at 1 month were (-0.39 ± 0.62) D in control group and (+0.73 ± 0.26) D in shallow anterior chamber group respectively which present statistical significance between the two groups (P = 0.00, t = 3.67); the postoperative refractive deviation in 3 month was (-0.37 ± 0.62) D in control group and (+0.79 ± 0.28) D in shallow anterior chamber group operatively which present statistical significance between the two groups (P = 0.00, t = 3.33). In shallow anterior chamber group, with the shallower of ACD, the greater of refractive deviation (P = 0.00, r1 month = -0.57, r3 months = -0.61). Hyperopic shift existed in age-related cataract patients with shallow anterior chamber and the shallower of ACD was, the greater of hyperopic shift happened.

To explore association between medically unexplained symptoms in children in Pakistan with emotional difficulties and functional impairments. We conducted a matched three-group case-control study of 186 children aged 8-16 years in Lahore, Pakistan. Cases were 62 children with chronic somatic symptoms for which no organic cause was identified after investigations. Two control groups of 62 children with chronic medical paediatric conditions, and 62 healthy children were identified. Cases and controls were matched for gender, age, and school class. Somatisation was measured with the Children's Somatisation Inventory (CSI-24) while anxiety and depression were measured with the Spencer Children's Anxiety Scale and the Short Mood and Feelings Questionnaire respectively. All questionnaires were translated into Urdu. Mean age was 11.7 years (SD=2.1). Cases scored significantly higher on somatisation (CSI-24), anxiety and depression than both control groups. Paediatric controls scored significantly higher than healthy controls on all three measures. Two hierarchical linear regression models were used to explore if somatisation predicted depression and anxiety while controlling for several confounders. Somatisation (higher CSI-24 scores) independently and significantly predicted higher anxiety (β=.37, p=.0001) and depression (β=.41, p=.0001) scores. This is the first study to show an association between medically unexplained symptoms and anxiety and depression in Pakistani children. This highlights the importance of screening for emotional difficulties in children presenting with unexplained somatic symptoms in this region. Copyright © 2013 Elsevier Inc. All rights reserved.

Summary Background Our main objective was to evaluate the association between autoimmune thyroiditis and the Delphian lymph node during different stages of thyroiditis. Material/Methods The relationships between the ultrasonography (US) results of thyroiditis and characteristics of the Delphian lymph node in different stages of AT were evaluated. Thyroid hormone and antibody levels were assessed. A total of 126 patients were divided into four groups according to the thyroid US findings: Group 1: control cases; Group 2: indeterminate cases; Group 3: established thyroiditis cases; Group 4: advanced-late stage thyroiditis cases. Indeterminate cases attended a 1-year follow-up, and the cases with a sonographic finding matching thyroiditis formed Group 2. Results The rate of Delphian lymph node presence in Group 4 was significantly higher than in Groups 1 and 2 (p<0.01). In addition, its presence was significantly higher in Group 3 than in Group 1 (p<0.05). Although there was a difference in Delphian lymph node presence between Groups 2 and 3, it was not significant (p=0.052), nor was there a significant difference between Groups 1 and 2 (p>0.05). Both the long and short axis measurements were significantly higher in Groups 2, 3, and 4 compared to those in the control group. However, the same increase was not observed in the long/short axis ratio. Conclusions Both the presence and dimensions of the Delphian lymph node were highly correlated with the progress of autoimmune thyroiditis. Evaluating the Delphian lymph nodes might prevent missing a diagnosis of autoimmune thyroiditis. PMID:26985243

Background Neural tubes defects (NTDs) are known to be the second most prevalent congenital disorder worldwide whose risk factors have not been explicitly addressed yet. Aim To determine the risk factors affecting NTDs among infants who referred to obstetrical centers in Kurdistan, a western province of Iran. Methods This prospective case-control study was conducted in the form of prospective case-control. Sample population included all women (27,153 cases) who referred to obstetrical centers in Kurdistan for either delivery or abortion during 2013 and 2014. Inclusion criterion was the presence of a known NTD in infants, and exclusion criterion was the reluctance of patients to participate in the study. Accordingly, 46 cases participated in the study as the case group, and 138 cases (three times higher than case group) were selected to be the control group. Case and control groups were matched in terms of the number of pregnancies and place of birth. The variables investigated in the present study were as follows: age, occupation, BMI, abortion history, family relation with husband, fetus’ sex, number of twins, history of previous children with NTD, receiving prenatal surveillance, consumption of folic acid and multivitamins, smoking, alcohol drinking, passive smoking, and suffering from such diseases as epilepsy and diabetes. Data were analyzed using various statistical tests, including chi-square, Fishers’ exact test, multiple logistic regression analysis using SPSS version 20. In the study group, inclusion criteria included all women who had an infant with tube defects that their total number was 46 individuals. In the control group inclusion criteria included mothers with healthy infants who were similar to the study group in terms of birth place and frequency of pregnancy. Results The results of the present study demonstrated that prenatal surveillance (p<0.002), multivitamin consumption (p<0.001), history of having a child with NTD (p<0.001), alcohol drinking (p<0.014), and passive smoking were related to NTDs (p<0.001). Conclusion Before fertilization and during pregnancy, mothers should be examined in terms of exposure to harmful agents, diet, and nutritional status in order to identify possible risk factors and find opportunities to prevent NTDs in infants.

Alveolar ridge preservation following tooth extraction has the ability to maintain the ridge dimensions and allow the implant placement in an ideal position fulfilling both functional and aesthetic results. The aim of this study was to evaluate the efficacy of the palatal connective tissue as a biological membrane for socket preservation with demineralized freeze-dried bone allograft (DFDBA). Twelve extraction sites were treated with DFDBA with (case group) and without (control group) using autogenous palatal connective tissue membrane before placement of implants. Alveolar width and height, amount of keratinized tissue, and gingival level were measured at pre-determined points using a surgical stent at two times, the time of socket preservation surgery. In both groups a decrease in all socket dimensions was found. The average decrease in socket width, height, keratinized tissue, and gingival level in case group was 1.16, 0.72, 3.58, and 1.27 mm, and in control group was 2.08, 0.86, 4.52, and 1.58 mm respectively. Statistical analysis showed that decrease in socket width (P = 0.012), keratinized tissue (P ≤ 0.001), and gingival level (P = 0.031) in case group was significantly lower than that of the control group. Results showed no meaningful difference in socket height changes when compared with case and control groups (P = 0.148). Under the limits of this study, connective tissue membrane could preserve socket width, amount of keratinized tissue, and the gingival level more effectively than DFDBA alone.

Retrospective studies suffer from drawbacks such as selection bias. As the selection of the control group has a significant impact on the evaluation of the results, it is very important to find the proper method to generate the most appropriate control group. In this paper we suggest two nearest neighbors based control group selection methods that aim to achieve good matching between the individuals of case and control groups. The effectiveness of the proposed methods is evaluated by runtime and accuracy tests and the results are compared to the classical stratified sampling method.

To identify the prevalence of dry eye in pediatric population with allergic conjunctivitis in Southwest China. A single-centre, prospective, case-control study conducted between May 2015 and December 2015 included 40 children, 3-6 years of age, with seasonal allergic conjunctivitis (SAC) or perennial allergic conjunctivitis (PAC) and 40 age- and gender-matched children undergoing medical healthy examination without history of allergy or dry eye as a control. A dry eye score system (DESS) was administered to both groups. Slit-lamp examinations including tear film break-up time (TFBUT) and fluorescent corneal staining (FCS) were performed. Correlation analyses were performed to evaluate associations between measures of dry eye and signs and symptoms of AC. The prevalence of dry eye was 97.5% (78/80 eyes) in cases and 27.50% (22/80 eyes) in controls. Mean DESS score was 4.75 ± 2.22 in the case group and 0.80 ± 1.22 in the control group (p < 0.001). Symptoms of dry eye in the case group were mild (<6). Mean tear film break-up time was 6.54 ± 1.48 seconds in the case group and 10.04 ± 1.79 seconds in the control group (p < 0.001). Mean FCS scores were 0.79 ± 1.34 and 0.21 ± 0.57, respectively (p = 0.001). The DESS score and TFBUT were both associated with the duration of allergic conjunctivitis. The incidence of dry eye assessed by TFBUT was higher in young children with SAC and PAC than in controls. However, subjective symptoms of dry eye (DESS) were inconsistent with objective signs, indicating that close attention should be paid to the evaluation and treatment of dry eye in pediatric population with AC. © 2016 Acta Ophthalmologica Scandinavica Foundation.

Introduction: One of the important tasks in managing labor is the protection of perineum. An important variable affecting this outcome is maternal pushing during the second stage of labor. This study was done to investigate the effect of breathing technique on perineal damage extention in laboring Iranian women. Materials and Methods: This randomized clinical trial was performed on 166 nulliparous pregnant women who had reached full-term pregnancy, had low risk pregnancy, and were candidates for vaginal delivery in two following groups: using breathing techniques (case group) and valsalva maneuver (control group). In the control group, pushing was done with holding the breath. In the case group, the women were asked to take 2 deep abdominal breaths at the onset of pain, then take another deep breath, and push 4–5 seconds with the open mouth while controlling exhalation. From the crowning stage onward, the women were directed to control their pushing, and do the blowing technique. Results: According to the results, intact perineum was more observed in the case group (P = 0.002). Posterior tears (Grade 1, 2, and 3) was considerably higher in the control group (P = 0.003). Anterior tears (labias) and episiotomy were not significantly different in the two groups. Conclusions: It was concluded that breathing technique of blowing can be a good alternative to Valsalva maneuver in order to reduce perineal damage in laboring women. PMID:28382061

We conducted a case-control and screening method studies to estimate influenza vaccine effectiveness (IVE) in the age group >or=65 years, based on the Spanish Influenza Sentinel Surveillance System (SISSS). Cases (influenza laboratory-confirmed) were compared to influenza-negative ILI patients (test-negative) and patients without ILI since the beginning of the season (non-ILI). For the screening method, cases' vaccination coverage was compared to the vaccination coverage of the GPs' catchment population. The results suggested a protective effect of the vaccine against laboratory-confirmed influenza in elderly in 2008-2009. The screening method and the test-negative control designs enable estimating IVE using exclusively SISSS data. (c) 2010 Elsevier Ltd. All rights reserved.

Stress causes an increase in cortisol and amylase. Recurrent aphthous stomatitis (RAS) results due to a multitude of causes, amongst which stress is one of the most important. Aim of the study was to estimate the level of stress, serum cortisol, salivary cortisol, amylase and electrolytes in subjects with RAS. 34 subjects with RAS (cases) were compared with 34 controls. Stress was measured using state trait anxiety inventory (STAI). Serum cortisol (Radioimmunoassay), Salivary cortisol, amylase (ELISA) and electrolytes (Flame photometry) were measured. Statistical analysis was done using SPSS 18.0 version software. The mean STAI scores were 48.71 ± 4.6 in cases and 46.74 ± 6.4 in controls (P = 0.13). The mean salivary cortisol concentration was 3.35 ± 1.8 ng/dl in cases and 3.65 ± 2.5 ng/dl in controls (P = 0.78). The mean salivary amylase was 155.09 ± 116.1 U/ml in cases and 128.74 ± 86.3 U/ml in controls (P = 0.49). The salivary sodium (0.24 ± 0.4 in both groups) and potassium (0.65 ± 0.5 in cases and 0.82 ± 0.4 in controls; P = 0.07) was not different in the two groups (electrolytes in mEq/dl). No correlation was seen between the salivary stress markers and STAI scores. Though stress was higher in RAS group none of the measured parameters were different from the control group. Stress may cause RAS but, in this study, there was no change in the salivary homeostasis.

The aim of this study was to test the hypothesis that the superficial middle cerebral vein (SMCV) is frequently absent or fails to connect with the cavernous sinus (CS) in the presence of brain arteriovenous malformations (AVMs), a frequently reported argument for the congenital origin of brain AVMs. The SMCV was retrospectively compared between patients with a brain AVM and a control group. The presence or absence of the SMCV, its direct or indirect connection to the CS and its termination in a laterocavernous sinus (LCS), paracavernous sinus (PCS), or directly in the CS was studied on digital subtraction angiography. One hundred twenty-five left or right side carotid angiograms from 70 patients with a brain AVM were compared to 125 angiograms from 74 controls. The SMCV was present in 88 (70.4 %) cases in the brain AVM group and 96 (76.8 %) cases in controls (p = 0.25). The SMCV was connected directly or indirectly to the CS in 65 (52 %) cases in the brain AVM group and 65 (52 %) cases in controls (p = 1). When comparing the subgroup of carotid angiograms ipsilateral to a supratentorial AVM, no statistically significant difference was found with controls. In three of six cases in which a SMCV drained an AVM, the vein terminated directly or indirectly in the CS. No difference of SMCV presence and direct or indirect connection to the CS was found between patients with AVM and a control group. SMCV anatomy does not support the congenital origin of brain AVMs.

The effects of soybean oligosaccharides (SBOS) on antioxidant enzyme activities and insulin resistance in pregnant women with gestational diabetes mellitus (GDM) were investigated. Ninety-seven pregnant women with GDM were randomly divided into two groups, the control group (51 cases) and the SBOS group (46 cases). Before the group separation, the blood sugar level in patients was maintained stable by regular diet and insulin treatment. The control group was continued with the insulin treatment, while the SBOS group was treated with the combination of insulin and SBOS. Results showed that SBOS were able to reduce oxidative stress and alleviate insulin resistance in pregnant women with GDM, which indicates that SBOS may play an important role in the control of GDM complications.

To identify the role of bilateral internal iliac artery (IIA) ligation on reducing blood loss in abnormally invasive placenta (AIP) undergoing caesarean hysterectomy. In this parallel-randomized control trial, 57 pregnant females with ultrasound features suggestive of AIP were enrolled. They were randomized into two groups; IIA group (n = 29 cases) performed bilateral IIA ligation followed by caesarean hysterectomies, while Control group (n = 28 cases) underwent caesarean hysterectomy only. The main outcome was the difference in the estimated intraoperative blood loss between the two groups. There was no significant difference between the two groups regarding the intraoperative estimated blood loss (1632 ± 804 versus 1698 ± 1251, p value .83). The operative procedure duration (minutes) (223 ± 66 versus 171 ± 41.4, p value .001) varied significantly between the two groups. Bilateral internal iliac artery ligation, in cases of AIP undergoing caesarean hysterectomy, is not recommended for routine practice to minimize blood loss intraoperatively.

Patients who survive hip fracture are at high risk of recurrent fractures, but rates of osteoporosis treatment 1 year after sustaining a fracture are less than 10% to 20%. We have developed an osteoporosis case manager intervention. The case manager educated patients, arranged bone mineral density tests, provided prescriptions, and communicated with primary care physicians. The intervention was compared with usual care in a randomized controlled trial. We recruited from all hospitals that participate in the Capital Health system (Alberta, Canada), including patients 50 years or older who had sustained a hip fracture and excluding those who were receiving osteoporosis treatment or who lived in a long-term care facility. Primary outcome was bisphosphonate therapy 6 months after fracture; secondary outcomes included bone mineral density testing, appropriate care (bone mineral density testing and treatment if bone mass was low), and intervention costs. We screened 2219 patients and allocated 220, as follows: 110 to the intervention group and 110 to the control group. Median age was 74 years, 60% were women, and 37% reported having had previous fractures. Six months after hip fracture, 56 patients in the intervention group (51%) were receiving bisphosphonate therapy compared with 24 patients in the control group (22%) (adjusted odds ratio, 4.7; 95% confidence interval, 2.4-8.9; P < .001). Bone mineral density tests were performed in 88 patients in the intervention group (80%) vs 32 patients in the control group (29%) (P < .001). Of the 120 patients who underwent bone mineral density testing, 25 (21%) had normal bone mass. Patients in the intervention group were more likely to receive appropriate care than were patients in the control group (67% vs 26%; P < .001). The average intervention cost was $50.00 per patient. For a modest cost, a case manager was able to substantially increase rates of osteoporosis treatment in a vulnerable elderly population at high risk of future fractures.

Annually, about 6000 new cases are diagnosed with breast cancer in Iran. In Iran, more women are affected with breast cancer than a decade earlier in comparison with other countries, and 70% of them are diagnosed at an advanced phase. Insomnia is the most common disorder following breast cancer, and interference in sleep quality and rest causes changes in physiological functions and reduces the body's daily performance. The objective of this study was to determine the effect of massage therapy on the quality of sleep in patients with breast cancer. This clinical trial was conducted for about 1 month in a referral chemotherapy clinic of a teaching hospital in Isfahan, Iran. The participants consisted of 57 women with breast cancer who were selected by simple random sampling. They were randomly assigned to two groups of control and experimental. The control group was treated only by usual medical therapy, whereas the case group was treated by combined medical-massage therapy. Data collection tools were the validated Pittsburgh Sleep Quality Index and a demographic questionnaire. Data were analyzed by SPSS using descriptive statistics, Chi-square test, paired t-test, and Student's t-test. The results showed significant differences in the mean scores of quality of sleep before and after the intervention in the case group, while no significant differences were observed in the mean scores of quality of sleep before and after the intervention in the control group. In addition, no significant differences were observed in the mean scores of quality of sleep before the intervention between case and control groups. However, significant differences were observed in the mean scores of quality of sleep after the intervention between case and control groups. According to the results of this study, learning and applying massage techniques by medical staff causes health promotion and improves the quality of sleep in cancer patients. Furthermore, massage therapy is suggested as a non-pharmacologic method to improve sleep quality in these patients.

To examine the changes in 25-hydroxyvitamin D 3 [25-(OH)D 3 ] level in children with Henoch-Schönlein purpura (HSP) and its clinical significance. A total of 92 HSP children were included in this study, and were divided into HSP nephritis (HSPN) group (31 cases) and HSP group (61 cases) based on the presence or absence of HSPN. Alternatively, the patients were divided into purpura alone group (22 cases), purpura with joint symptoms group (joint symptom group, 24 cases), purpura with gastrointestinal symptoms group (gastrointestinal symptom group, 20 cases), and purpura with joint and gastrointestinal symptoms (mixed group, 26 cases) based on their clinical symptoms. In addition, 42 healthy children were selected as healthy control group. The level of 25-(OH)D 3 in each group was measured using enzyme-linked immunoassay. The 25-(OH)D 3 level in the HSP and HSPN groups was significantly lower than that in the healthy control group (P<0.05), and the 25-(OH)D 3 level in the HSPN group was significantly lower than that in the HSP group (P<0.05). Although there was no significant difference in the 25-(OH)D 3 level between the joint symptom, gastrointestinal symptom, and mixed groups (P=0.22), the 25-(OH)D 3 level in the three groups was all significantly lower than that in the purpura alone group (P<0.05). The level of 25-(OH)D 3 is reduced in children with HSP, particularly those with HSPN or with joint and gastrointestinal symptoms. Therefore, the reduction in 25-(OH)D 3 level may serve as a predictor of whether HSP is associated with other impairments.

Breech presentation occurs in up to 3% of pregnancies at term and may be an indication for caesarean delivery. External cephalic version can be effective in repositioning the fetus in a cephalic presentation, but may be painful for the mother. Our aim was to assess the efficacy of remifentanil versus placebo for pain relief during external cephalic version. A randomized, double-blind, controlled trial that included women at 36-41 weeks of gestation with non-cephalic presentations was performed. Women were randomized to receive either a remifentanil infusion at 0.1 μg/kg/min and demand boluses of 0.1 μg/kg, or saline placebo. The primary outcome was the numerical rating pain score (0-10) after external cephalic version. Sixty women were recruited, 29 in the control group and 31 in the remifentanil group. There were significant differences in pain scores at the end of the procedure (control 6.5 ± 2.4 vs. remifentanil 4.7 ± 2.5, P = 0.005) but not 10 min later (P = 0.054). The overall success rate for external cephalic version was 49% with no significant differences between groups (remifentanil group 54.8% vs. control group 41.3%, P = 0.358). In the remifentanil group, there was one case of nausea and vomiting, one of drowsiness and three cases of fetal bradycardia. In the control group, there were three cases of nausea and vomiting, one of dizziness and nine cases of fetal bradycardia. Intravenous remifentanil with bolus doses on demand during external cephalic version achieved a reduction in pain and increased maternal satisfaction. There were no additional adverse effects, and no difference in the success rate of external cephalic version or the incidence of fetal bradycardia. Copyright © 2013 Elsevier Ltd. All rights reserved.

It has been suggested that recall bias may explain the discrepant results between case-control and cohort studies on diet and the risk of breast cancer. Two control groups were used for this case-control study of 25 to 75-year-old breast cancer cases (n = 310). The first group consisted of population controls drawn from the Finnish National Population Register (n = 454). The second group consisted of women who were referred to the same examinations as were the cases because of clinical suspicion of breast disease but who were later diagnosed as healthy (referral controls; n = 506). Because the diagnosis was unknown at the time of interview, it was possible to assess by comparing the two control groups whether the self-reporting of diet changed under the threat of disease. Dietary habits were examined using a validated, self-administered food-frequency questionnaire. Premenopausal women misreported their consumption of liquid milk products, tea, and sugar. Reporting bias was also associated with the intake of fat and vitamins. Postmenopausal women misreported consumption of milk products. When recall bias was taken into consideration, milk was associated with increased risk of premenopausal breast cancer, whereas high consumption of poultry or high intake of monounsaturated fatty acids, n-3 fatty acids, n-6 fatty acids, and vitamin E were related to lower risk. The study suggested that oil, milk, cheese, coffee and beta-carotene may act as protective factors in postmenopausal women, whereas butter and cream may be risk factors for breast cancer. In summary, it is possible that some food items may be overreported or underreported under the threat of disease in health-conscious population. However, most of the results in this study were not modified by recall bias.

To make multi-central clinical evaluation for three-part massage therapy for treatment of insomnia of deficiency of both the heart and spleen. One hundred and sixty-six cases were randomly divided into a test group (n = 84) and a control group (n = 82). Multi-central, randomized and controlled methods were adopted. The test group were treated by the three-part massage therapy, i. e. acupoints at the head, abdomen and back were massaged, once each day; and the control group by oral administration of Guipi Pills [symbol: see text], 8 pills each time, thrice daily. The treatment was given for 15 consecutive days and then the therapeutic effects were observed. Sixty-seven cases were cured, 11 markedly effective, 3 effective, and 3 ineffective in the test group, and the corresponding figures were 10, 21, 29 and 22 in the control group with a very significant difference between the two groups (P< 0.001). The test group was superior to the control group in improvement for Pittsburgh Sleep Quality Index (PSQI), Sleepless Anxiety Scale (SAS) and Sleepless Depression Scale (SDS) (P < 0.001). The three-part massage therapy has definite therapeutic effect on insomnia of deficiency of both the heart and spleen with safety.

Understanding glioma etiology requires determining which environmental factors are associated with glioma. Upper Midwest Health Study case-control participant work histories collected 1995-1998 were evaluated for occupational associations with glioma. "Exposures of interest" from our study protocol comprise our a priori hypotheses. Year-long or longer jobs for 1,973 participants were assigned Standard Occupational Classifications (SOC) and Standard Industrial Classifications (SIC). The analysis file includes 8,078 SIC- and SOC-coded jobs. For each individual, SAS 9.2 programs collated employment with identical SIC-SOC coding. Distributions of longest "total employment duration" (total years worked in jobs with identical industry and occupation codes, including multiple jobs, and non-consecutive jobs) were compared between cases and controls, using an industrial hygiene algorithm to group occupations. Longest employment duration was calculated for 780 cases and 1,156 controls. More case than control longest total employment duration was in the "engineer, architect" occupational group [16 cases, 10 controls, odds ratio (OR) 2.50, adjusted for age group, sex, age and education, 95% confidence interval (CI) 1.12-5.60]. Employment as a food processing worker [mostly butchers and meat cutters] was of borderline significance (27 cases, 21 controls, adjusted OR: 1.78, CI: 0.99-3.18). Among our exposures of interest work as engineers or as butchers and meat cutters was associated with increased glioma risk. Significant associations could be due to chance, because of multiple comparisons, but similar findings have been reported for other glioma studies. Our results suggest some possible associations but by themselves could not provide conclusive evidence. Copyright © 2012 Wiley Periodicals, Inc.

Objective. The aim of the study is to investigate the possible associations between the blood groups ABO and Rhesus systems and the presence of keloids in patients with black skin. Method. This case-control study was conducted between September 2007 and August 2011 comparing dermatologic outpatients with keloids to matched controls recruited in preanesthetic consultation at Tokoin Teaching Hospital of Lomé (Togo). Results. The distribution of different ABO blood groups and Rhesus blood groups in both groups (cases versus controls) was not significantly different. This distribution of different blood groups was superimposed on the general population of blood donors at the National Blood Transfusion Center of Lomé. Univariate analysis between each blood group and the presence of keloid does not yield any statistically significant association between blood groups and presence of keloids in the subjects. Conclusion. The study shows no significant association between blood groups and the presence of keloids in our patients. Further investigation needs to be conducted to elucidate this hypothesis further by conducting multicenter studies of several ethnic groups.

Acute respiratory tract infections (ARTIs) are responsible for considerable morbidity in the community, but little is known about the presence of respiratory pathogens in asymptomatic individuals. We hypothesized that asymptomatic persons could have a subclinical infection and thus act as a source of transmission. During the period of 2000-2003, all patients with ARTI who visited their sentinel general practitioner had their data reported to estimate the incidence of ARTI in Dutch general practices. A random selection of these patients (case patients) and an equal number of asymptomatic persons visiting for other complaints (control subjects) were included in a case-control study. Nose and throat swabs of participants were tested for a broad range of pathogens. The overall incidence of ARTI was 545 cases per 10,000 person-years, suggesting that, in the Dutch population, an estimated 900,000 persons annually consult their general practitioner for respiratory complaints. Rhinovirus was most common in case patients (24%), followed by influenza virus type A (11%) and coronavirus (7%). Viruses were detected in 58% of the case patients, beta -hemolytic streptococci group A were detected in 11%, and mixed infections were detected in 3%. Pathogens were detected in approximately 30% of control subjects, particularly in the youngest age groups. This study confirms that most ARTIs are viral and supports the reserved policy of prescribing antibiotics. In both case and control subjects, rhinovirus was the most common pathogen. Of bacterial infections, only group A beta-hemolytic streptococci were more common in case patients than in control subjects. Furthermore, we demonstrated that asymptomatic persons might be a neglected source of transmission.

In May 2015, a cholera outbreak that had lasted 3 months and infected over 100 people was reported in Kasese District, Uganda, where multiple cholera outbreaks had occurred previously. We conducted an investigation to identify the mode of transmission to guide control measures. We defined a suspected case as onset of acute watery diarrhoea from 1 February 2015 onwards in a Kasese resident. A confirmed case was a suspected case with Vibrio cholerae O1 El Tor, serotype Inaba cultured from a stool sample. We reviewed medical records to find cases. We conducted a case-control study to compare exposures among confirmed case-persons and asymptomatic controls, matched by village and age-group. We conducted environmental assessments. We tested water samples from the most affected area for total coliforms using the Most Probable Number (MPN) method. We identified 183 suspected cases including 61 confirmed cases of Vibrio cholerae 01; serotype Inaba, with onset between February and July 2015. 2 case-persons died of cholera. The outbreak occurred in 80 villages and affected all age groups; the highest attack rate occurred in the 5-14 year age group (4.1/10,000). The outbreak started in Bwera Sub-County bordering the Democratic Republic of Congo and spread eastward through sustained community transmission. The first case-persons were involved in cross-border trading. The case-control study, which involved 49 confirmed cases and 201 controls, showed that 94% (46/49) of case-persons compared with 79% (160/201) of control-persons drank water without boiling or treatment (OR M-H =4.8, 95% CI: 1.3-18). Water collected from the two main sources, i.e., public pipes (consumed by 39% of case-persons and 38% of control-persons) or streams (consumed by 29% of case-persons and 24% control-persons) had high coliform counts, a marker of faecal contamination. Environmental assessment revealed evidence of open defecation along the streams. No food items were significantly associated with illness. This prolonged, community-wide cholera outbreak was associated with drinking water contaminated by faecal matter and cross-border trading. We recommended rigorous disposal of patients' faeces, chlorination of piped water, and boiling or treatment of drinking water. The outbreak stopped 6 weeks after these recommendations were implemented.

The role of dietary factors in the pathophysiology of acne vulgaris is highly controversial. Hence, the aim of this study was to determine the association between dietary factors and acne vulgaris among Malaysian young adults. A case-control study was conducted among 44 acne vulgaris patients and 44 controls aged 18 to 30 years from October 2010 to January 2011. Comprehensive acne severity scale (CASS) was used to determine acne severity. A questionnaire comprising items enquiring into the respondent's family history and dietary patterns was distributed. Subjects were asked to record their food intake on two weekdays and one day on a weekend in a three day food diary. Anthropometric measurements including body weight, height and body fat percentage were taken. Acne severity was assessed by a dermatologist. Cases had a significantly higher dietary glycemic load (175 ± 35) compared to controls (122 ± 28) (p < 0.001). The frequency of milk (p < 0.01) and ice-cream (p < 0.01) consumptions was significantly higher in cases compared to controls. Females in the case group had a higher daily energy intake compared to their counterparts in the control group, 1812 ± 331 and 1590 ± 148 kcal respectively (p < 0.05). No significant difference was found in other nutrient intakes, Body Mass Index, and body fat percentage between case and control groups (p > 0.05). Glycemic load diet and frequencies of milk and ice cream intake were positively associated with acne vulgaris.

Background Although a rare disease, uveal melanoma is the most common primary intraocular malignancy in adults, with an incidence rate of up to 1.0 per 100,000 persons per year in Europe. Only a few consistent risk factors have been identified for this disease. We present the study design of an ongoing incident case-control study on uveal melanoma (acronym: RIFA study) that focuses on radiofrequency radiation as transmitted by radio sets and wireless telephones, occupational risk factors, phenotypical characteristics, and UV radiation. Methods/Design We conduct a case-control study to identify the role of different exposures in the development of uveal melanoma. The cases of uveal melanoma were identified at the Division of Ophthalmology, University of Essen, a referral centre for tumours of the eye. We recruit three control groups: population controls, controls sampled from those ophthalmologists who referred cases to the Division of Ophthalmology, University of Duisburg-Essen, and sibling controls. For each case the controls are matched on sex and age (five year groups), except for sibling controls. The data are collected from the study participants by short self-administered questionnaire and by telephone interview. During and at the end of the field phase, the data are quality-checked. To estimate the effect of exposures on uveal melanoma risk, we will use conditional logistic regression that accounts for the matching factors and allows to control for potential confounding.

Musculoskeletal injuries among health care workers is very high, particularly so in direct care workers involved in patient handling. Efforts to reduce injuries have shown mixed results, and strong evidence for intervention effectiveness is lacking. The purpose of our study was to evaluate the effectiveness of a Transfer, Lifting and Repositioning (TLR) program to reduce musculoskeletal injuries (MSI) among direct health care workers. This study was a pre- and post-intervention design, utilizing a nonrandomized control group. Data were collected from the intervention group (3 hospitals; 411 injury cases) and the control group (3 hospitals; 355 injury cases) for periods 1 year pre- and post-intervention. Poisson regression analyses were performed. Of a total 766 TLR injury cases, the majority of injured workers were nurses, mainly with back, neck, and shoulder body parts injured. Analysis of all injuries and time-loss rates (number of injuries/100 full-time employees), rate ratios, and rate differences showed significant differences between the intervention and control groups. All-injuries rates for the intervention group dropped from 14.7 pre-intervention to 8.1 post-intervention. The control group dropped from 9.3 to 8.4. Time-loss injury rates decreased from 5.3 to 2.5 in the intervention group and increased in the control group (5.9 to 6.5). Controlling for group and hospital size, the relative rate of all-injuries and time-loss injuries for the pre- to post-period decreased by 30% (RR = 0.693; 95% CI = 0.60-0.80) and 18.6% (RR = 0.814; 95% CI = 0.677-0.955), respectively. The study provides evidence for the effectiveness of a multifactor TLR program for direct care health workers, especially in small hospitals.

Background This study investigated whether deliberate practice leads to an increase in surgical quality in virtual reality (VR) laparoscopic cholecystectomies (LC). Previous research has suggested that sustained DP is effective in surgical training. Methods Fourteen residents were randomized into deliberate practice (n=7) or control training (n=7). Both groups performed 10 sessions of two VR LCs. Each session, the DP group was assigned 30 minutes of DP activities in between LCs while the control group viewed educational videos or read journal articles. Performance was assessed on speed and dexterity; quality was rated with global (GRS) and procedure-specific (PSRS) rating scales. All participants then performed five porcine LCs. Results Both groups improved over 20 VR LCs in time, dexterity, and global rating scales (all p<0.05). After 20 LCs, there were no differences in speed or dexterity between groups. The DP group achieved higher quality of VR surgical performance than control for GRS (26 vs. 20, p=0.001) and PSRS (18 vs. 15, p=0.001). For VR cases, DP subjects plateaued at GRS=25 after 10 cases and control group at GRS=20 after five cases. At completion of VR training, 100% of the DP group reached target quality of performance (GRS≥21) compared to 30% in the control group. There were no significant differences for improvements in time or dexterity over five porcine LCs. Conclusion This study suggests that DP leads to higher quality performance in VR LC than standard training alone. Standard training may leave individuals in a state of “arrested development” compared to DP. PMID:25539697

To compare the differences in the clinical therapeutic effects on chronic knee joint pain between the combination of the central-square needling technique of thumb-tack needles with the routine therapy of acupuncture, moxibustion and tuina and the routine therapy of acupuncture, moxibustion and tuina . One hundred and twenty patients of chronic knee joint pain were randomized into an observation group and a control group, 60 cases in each one. In the control group, the routine therapy of acupuncture, moxibustion and tuina was adopted. In the observation group, at the end of treatment with the routine therapy of acupuncture, moxibustion and tuina , the subcutaneous embedding therapy was followed with four thumb-tack needles at the sites 1 to 1.5 cm above, below and bilateral to the main point ( ashi point) separately, and the needles were retained for 24 h to 48 h. The treatment was given once every two days, three times a week, totally 6 times in two weeks; and the follow-up visit was done for 3 months in patients of the two groups. The visual analogue scale (VAS) score before and after each treatment, Lequesne index score before treatment and at the end of follow-up and the case numbers of proactive use of painkillers or receiving acupuncture treatment in the follow-up stage were compared and observed in the patients of the two groups. The VAS score was reduced gradually after treatment in the patients of the two groups. The differences were significant statistically after the second treatment as compared with those before the treatment in the two groups (all P <0.05), in which, the improvements in VAS scores after the third treatment in the observation group were more obvious than those in the control group (all P <0.05). At the end of follow-up visit, Lequesne index scores were all improved as compared with those before treatment in the two groups (both P <0.05) and the improvements were similar between the two groups ( P >0.05). In the follow-up stage, there were 0 case in the observation group and 9 cases in the control group in terms of proactive use of painkillers ( P <0.05). There were 5 cases in the observation group and 1 case in the control group receiving acupuncture treatment again ( P >0.05). The acupuncture scheme in assistance with the central-square needling technique of thumb-tack needles obviously relieves chronic knee joint pain, much better sustains the analgesic effects of acupuncture and improves patient compliance.

The aim is to estimate the relative risk and population attributable risk (PAR) of risk factors for ischemic stroke by ethnic group. In this case-control study, cases of first ischemic stroke were taken from the South London Stroke Register and controls from a cross-sectional prevalence survey covering the same area. PAR was determined for each risk factor by ethnic group. Multivariable analysis was used to examine the association between risk factors and ischemic stroke across all ethnic groups. 664 cases and 716 controls aged 45 to 74 years were included, with ethnicity of white 78%:42%, black Caribbean 16%:43%, and black African 6%:15%, respectively. For the white group, high PAR was found for ischemic heart disease (IHD) on ECG (56% [95% CI, 49% to 62%]), obesity (49% [95% CI, 40% to 56%]), hypertension (HT) (38% [95% CI, 29% to 46%]), smoking (31% [95% CI, 19% to 41%]), transient ischemic attack (TIA) (23% [95% CI, 19% to 27%]), and atrial fibrillation (AF) (16% [95% CI, 10% to 21%]). In the black Caribbean compared with the white group, PAR was higher for HT (46% [95% CI, 21% to 63%]) and diabetes mellitus (DM) (29% [95% CI, 14% to 42%]), and lower for current smoking (18% [95% CI, 1% to 32%]) and AF (10% [95% CI, 0% to 18%]). In the black African group HT had a higher PAR (59% [95% CI, 91% to 82%]) than the other groups. PAR for AF (11% [95% CI, -11% to 29%]), obesity (30% [95% CI, -20% to 60%]), and DM (4% [95% CI, -25% to 26%]) was low compared with the other groups. In multivariable analysis, risk factors associated with ischemic stroke included TIA, AF, IHD on ECG, smoking, excess alcohol, obesity, HT, and DM. In the first European case-control study examining risk factors for ischemic stroke in black Caribbean and African populations, some differences were demonstrated in the impact of risk factors between these groups. It may be important to address such differences when developing stroke preventative strategies.

Endotoxins are known to be associated with the occurrence of various chronic diseases. This study was conducted to investigate the role of endotoxins in the pathogenesis of colon polyps through a case-control study. A total of 145 subjects (74 subjects in the polyp group and 71 subjects in the control group) had undergone a colonoscopy. Age, body mass index (BMI) and endotoxin levels were found to be significantly higher in the polyp group than in the control group. The endotoxin level was still significantly higher in the polyp group than in the control group, even after age and BMI had been adjusted (polyp group 0.108 ± 0.007 EU/mL, control group 0.049 ± 0.008 EU/mL, P < 0.001). In subgroup analysis, the endotoxin level significantly increased in accordance with the number of colon polyps (one-polyp group, 0.088 ± 0.059 EU/mL; two-polyp group, 0.097 ± 0.071 EU/mL; three-or-more-polyp group, 0.149 ± 0.223 EU/mL). The endotoxin levels also significantly increased in groups with tubular adenoma with high-grade dysplasia (hyperplastic polyp group, 0.109 ± 0.121 EU/mL; tubular adenoma with low grade dysplasia group, 0.103 ± 0.059 EU/mL; tubular adenoma with high grade dysplasia group, 2.915 ± 0.072 EU/mL). In conclusion, the serum level of endotoxins is quantitatively correlated with colon polyps. PMID:22969253

To estimate prevalence of exposure to environmental tobacco smoke and other environmental toxins in dogs with primary lung tumours and to analyse association between exposure and lung tumour development. In this case-control study, an owner survey was developed to collect data on patient characteristics, general health care and environmental exposures. Dogs diagnosed with primary lung carcinomas formed the Case group. Dogs diagnosed with mast cell tumours served as Control Group 1 and dogs diagnosed with neurologic disease served as Control Group 2. Associations between diagnosis of primary lung tumour and patient and environmental exposure variables were analysed using bivariate and multivariate statistical methods. A total of 1178 owner surveys were mailed and 470 surveys were returned and included in statistical analysis, including 135 Cases, 169 dogs in Control Group 1 and 166 dogs in Control Group 2. An association between exposure to second-hand smoke and prevalence of primary lung cancer was not identified in this study. Second-hand smoke is associated with primary lung cancer in people but a definitive association has not been found in dogs. The results of this study suggest that tobacco smoke exposure may not be associated with primary lung cancer development in dogs but study limitations may have precluded detection of an association. © 2017 British Small Animal Veterinary Association.

This case-control study was designed to evaluate the association of three COL2A1 single nucleotide polymorphism (SNPs) (rs1793953, rs2276454, and rs1793937) and Aggrecan variable number of tandem repeat (VNTR) polymorphisms with the risk and clinicopathological features of intervertebral disc degeneration (IVDD) in a Chinese Han population. Data from 295 IVDD patients (case group) and 324 healthy volunteers (control group) were collected between January 2012 and December 2014. Magnetic resonance examinations were conducted on all included subjects. The frequency distributions of the COL2A1 and Aggrecan polymorphisms were detected using direct sequencing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis, respectively. The genotype and allele frequencies of the COL2A1 genetic polymorphisms (rs1793953 and rs2276454) and the Aggrecan VNTR polymorphisms differed significantly between the case group and the control group (all p < 0.05). The haplotype analysis indicated that the frequencies of ACGL (L, long) and GTCL haplotypes were lower in the case group than in the control group (both p < 0.05). In the case group, the genotype and allele frequencies of the COL2A1 genes, rs1793953 and rs2276454, and Aggrecan VNTR significantly differed in terms of Pfirrmann grades III, IV, and V (all p < 0.05). Personal history of spine sprain or crush injury, history of IVDD in a first-degree relative, and COL2A1 rs2276454 and Aggrecan VNTR presence may be independent risk factors of IVDD (all p < 0.05, odds ratio [OR] >1), whereas tea drinking habit, part-time sports participation, and COL2A1 rs1793953 presence may be protective factors of IVDD (all p < 0.05, OR <1). Our study provides evidence that COL2A1 and Aggrecan genetic polymorphisms may be correlated with the risk and clinicopathological features of IVDD in a Chinese Han population, and ACGL and GTCL haplotypes may be protective factors of IVDD.

We introduce a grouping system for clinical practice which allows the separation of DRG coding in specific orthopaedic groups based on anatomic regions, operative procedures, therapeutic interventions and morbidity equivalent diagnosis groups. With this, a differentiated aim-oriented analysis of illustrated internal DRG data becomes possible. The group-specific difference of the coding quality between the DRG groups following primary coding by the orthopaedic surgeon and final coding by the medical controlling is analysed. In a consecutive series of 1600 patients parallel documentation and group-specific comparison of the relevant DRG parameters were carried out in every case after primary and final coding. Analysing the group-specific share in the additional CaseMix coding, the group "spine surgery" dominated, closely followed by the groups "arthroplasty" and "surgery due to infection, tumours, diabetes". Altogether, additional cost-weight-relevant coding was necessary most frequently in the latter group (84%), followed by group "spine surgery" (65%). In DRGs representing conservative orthopaedic treatment documented procedures had nearly no influence on the cost weight. The introduced system of case group analysis in internal DRG documentation can lead to the detection of specific problems in primary coding and cost-weight relevant changes of the case mix. As an instrument for internal process control in the orthopaedic field, it can serve as a communicative interface between an economically oriented classification of the hospital performance and a specific problem solution of the medical staff involved in the department management.

We investigated the application of Alberta Infant Motor Scale (AIMS) in screening motor development delay in the follow-up of high-risk infants who were discharged from NICU, to explain the state of infants' motor development and propose early individualized intervention. The study design was a randomized, single-blind trial by selecting patients between April 2015 and November 2015 in our hospital, children nerve recovery branch clinics and 77 cases of high-risk infants. We randomly divided the patients into observation group (39 cases) and control group (38 cases). To evaluate the application with AIMS, observation group was based on evaluation results for the first time to give rehabilitation training plan making, early intervention, control group according to the growth and development milestone in order to guide parents to take family training interval of 3 months. While comparing the two groups of high-risk infants before the intervention, the months of age, gender, risk factors, it was found that the AIMS scores, each position AIMS scores did not show a significant difference in percentile (p>0.05). There was also no significant difference between two groups in the seat and stand AIMS scores before and after intervention (p>0.05). However, the comparison of two groups of high-risk infants after intervention in comparison showed that the observation group supine AIMS scores and AIMS scores were significantly higher than the control group (p<0.05). Prone position AIMS scores observation group was also significantly higher than that of the control group (p<0.01). The corresponding percentile for two groups after the intervention of AIMS scores was less than 10% of cases, which was significantly lower in the observation group (p<0.01). AIMS can predict the development delay in high-risk infants, for improving the early hypernymic diagnosis and intervention.

The study aimed to investigate the correlations of CACNA1C genetic polymorphisms and protein expression with the pathogenesis of schizophrenia in a Chinese population. This research included 139 patients diagnosed with schizophrenia (case group) and 141 healthy volunteers (control group). Case and control samples were genotyped using denaturing high-performance liquid chromatography (DHPLC). Haplotypes of rs10848683, rs2238032, and rs2299661 were analyzed using the Shesis software. A mouse model of schizophrenia was established and assigned to test and blank groups. Western blotting was used to detect CACNA1C protein expression. The genotype and allele distribution of rs2238032 and rs2299661 differed between the case and control groups. TT genotype of rs2238032 and G allele of rs2299661 could potentially reduce the risk of schizophrenia. The distribution of rs2238032 genotype has a close connection with cognitive disturbance and the results of the general psychopathology classification exam. The distribution of rs2299661 genotypes was closely related to sensory and perceptual disorders, negative symptom subscales, and the results of the general psychopathology classification exam. CTC haplotype increased and CTG decreased the risk of schizophrenia in healthy people. In the brain tissues of mice with schizophrenia, the CACNA1C protein expression was higher in the test group than in the blank group. Our study demonstrated that CACNA1C gene polymorphisms and CACNA1C protein expression were associated with schizophrenia and its clinical phenotypes.

To investigate the clinical effect of hemoperfusion combined with hemodialysis in the treatment of severe organophosphate pesticide poisoning. Ninety-eight patients with severe organophosphate pesticide poisoning who were admitted to the emergency department of our hospital from March 2005 to September 2013 were equally divided into control group and observation group according to treatment methods. The control group was given conventional emergency treatment, while the observation group was given hemoperfusion combined with hemodialysis and the conventional emergency treatment. The clinical outcomes and complications of two groups were compared. In the control group, 35 patients were cured and 14 patients died, so the cure rate was 71.4%. In the treatment group, 46 patients were cured and 3 patients died, so the cure rate was 93.9%. The treatment group had a significantly higher cure rate than the control group (χ² = 8.611, P < 0.05). And the treatment group had significantly shorter duration of coma (P < 0.01), mean length of hospital stay (P < 0.01), and time to recovery of cholinesterase activity (P < 0.01) and a significantly reduced dose of atropine than the control group (P < 0.01). The control group had significantly more cases of urinary retention than the treatment group (18 vs. 6, χ² = 4.991, P < 0.05). And the control group had more cases of intermediate syndrome, respiratory failure, delayed neurological damage, and rebound than the treatment group. Hemoperfusion combined hemodialysis has a good clinical effect and causes fewer complications in treating severe organophosphate pesticide poisoning, so it is worthy of clinical promotion.

To study the efficacy of short-term educational intervention for parents of preschool children with anxiety. Forty-nine children with Spence Preschool Anxiety Scale (SPAS) scores of ≥ 48 were randomly divided into intervention and control groups. The children's parents in the intervention group received a collective curriculum on children's anxiety management six times, while the control group was only followed up. All children were evaluated for anxiety by the SPAS 3 and 6 months later, and then the results were compared between the two groups. The test was completed in 21 cases of the intervention group and 22 cases of the control group. At month 3, the intervention group had a significantly lower percentage of children with SPAS scores of ≥ 48 than the control group (62% vs 91%; P<0.05), and this percentage was also significantly lower in the intervention group than in the control group at month 6 (52% vs 82%; P<0.05). At month 3, the intervention group had a significantly reduced mean SPAS score, which was significantly lower than that of the control group (69 ± 12 vs 81 ± 12; P<0.01). At month 6, both groups showed significant decreases in SPAS score, but still the SPAS score was significantly lower in the intervention group than in the control group (65 ± 13 vs 78 ± 13; P<0.01). Early short-term education for parents can relieve their preschool children's anxiety effectively, but the long-term effect needs to be evaluated by follow-up.

The aim of this study was to investigate whether the use of fenoterol, a beta2-adrenergic agonist, was associated with multiple sclerosis (MS) risk by conducting a total population-based case-control study in Taiwan. A total of 578 patients with newly diagnosed MS who had a severely disabling disease (SDD) certificate between January 1, 2002 and December 1, 2008 comprised the case group. These cases were compared with 2890 gender-, age-, residence-, and insurance premium-matched controls. Fenoterol use was analyzed using a conditional logistic regression model that controlled for asthma, chronic obstructive pulmonary disease (COPD), salbutamol and steroid use. Compared with the group of people who did not use fenoterol, the adjusted odds ratios were 0.67 (95% confidence interval (CI) = 0.48-0.93, p = 0.016) for the group prescribed fenoterol below 2.25 cumulative defined daily dose (cDDD) and 0.49 (95% CI = 0.33-0.71, p < 0.001) for the group with a cumulative fenoterol use of more than 2.25 cDDD. The dose-response relationship was similar within the non-asthma patients. The associations were similar between males and females, but differences between age groups were observed. The results of this study suggest that fenoterol use may reduce the risk of MS. © The Author(s), 2014.

The association between urinary tract infection (UTI) of pregnant women and preterm birth/low birthweight is known, but the possible association between UTI and congenital abnormalities (CAs) was evaluated rarely. Only one study showed an association with atrial septal defect, thus we decided to check this possible association. The population-based large data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities (HCCSCA); most maternal UTIs were based on medically recorded data. SETTING The HCCSCA, 1980-1996, contained 22 843 newborns or fetuses with CAs and 38 151 matched controls, i.e. newborn infants without any HCAs. Hungarian informative offspring: live births, stillbirths and prenatally diagnosed malformed fetuses. Case-control pair analysis. Twenty-five CA groups. A total of 1542 (6.75%) mothers in the case group had UTI during entire pregnancy compared with 2188 (5.74%) mothers in the control group (adjusted prevalence odds ratios [POR] with 95% CI: 1.15, 1.06-1.24). We did not find a higher prevalence of UTI during the second and/or third months of pregnancy in total case group (adjusted POR with 95% CI: 1.1, 0.9-1.2) and in any group of CAs including atrial septal defect type II. No evidence for the teratogenic effect of maternal UTI and related drug treatments during early pregnancy.

Intelligence quotients (IQs) were measured in 15 children hospitalized in their 1st 2 years with 3rd degree malnutrition and in their siblings of closest age who had no history of hospitalization for malnutrition. Clinical records were reviewed of 459 malnourished infants admitted to the Dr. Robert Reid Cabral Hospital in Santo Domingo between January 1976-January 1977. 230 of the children had died, and 15 of the 57 survivors who returned to the hospital for a preliminary interview were selected as subjects. Their closely aged siblings served as controls. Both groups were given Bender's visual-motor test and Weschler's intelligence scale for children. The ages of the subjects were 7-0 years and of siblings 6-13 years. Children who had spent a greater number of days in the hospital appeared to have a greater degree of mental impairment. 2 of the children with marasmus presented moderate mental retardation, 1 slight retardation, and another borderline retardation. The controls for these 5 cases included 1 moderately retarded, 2 slightly retarded, and 1 borderline case. 1 child with marasmus who was removed from his home showed a normal intelligence while his control who had remained in the home had a slight retardation. There was no consistent relationship between the cephalic perimeter and the IQ score, although 40% of the malnourished children and 30% of controls had perimeters below the normal range. 20% of cases and no controls required more than 18 months to learn to walk. Cases were also slower than controls to begin speaking and to be toilet trained. The tests showed that the control group members had somewhat higher intelligence quotients than the malnourished group. 53.2% of the malnourished children had IQs far below normal at 60-69, compared to 39.9% of controls. 93% of the study group and 87% of controls had IQs below normal values of 80-89. But there was no statistically significant difference in average IQs: 72.2 + or - 17.5 in the study group and 75.3 + or - 11.2 in the control group. Because both groups had low IQ scores, it was concluded that environmental factors played a strong role in development of intelligence. Low income, parental education, and large family sizes were all believed to be important.

Little research has been done on the effects of hyperbaric oxygen (HBO) on depression and anxiety after spinal cord injury (SCI). The aim of this study was to investigate the effects of HBO on psychological problems and never function, especially on depression and anxiety in the patients with incomplete SCI (ISCI).Sixty patients with ISCI combined with depression and anxiety were randomly divided into HBO group (20 cases), psychotherapy group (20 cases), and conventional rehabilitation control group (20 cases). All patients received routine rehabilitation therapy. However, in HBO group and psychotherapy group, patients also received HBO and psychotherapy, respectively. These therapies lasted for a total of 8 weeks (once a day and 6 days per week). Before and after 8 weeks of treatment, depression and anxiety, nerve function, and activities of daily living were, respectively, evaluated according to Hamilton Depression (HAMD) scale, Hamilton Anxiety (HAMA) scale, American Spinal Injury Association score, and functional independence measure score in all patients.After 8 weeks of treatment, HAMD score was significantly lower in both HBO group and psychotherapy group than in control group (all P < .05), but there was no statistical difference in HAMD score between HBO group and psychotherapy group (P > .05). HAMA score was significantly lower in HBO group than in control group (P < .05), but there was no statistical difference in HAMA score between HBO group and psychotherapy group, and between psychotherapy group and control group (all P > .05). After 8 weeks of treatment, American Spinal Injury Association and functional independence measure scores were significantly higher in HBO group than in both psychological and control groups, and also higher in psychotherapy group than in control group (all P < .05).The effects of HBO on depression and anxiety are similar to that of psychotherapy. HBO can significantly improve nerve function and activities of daily living in the patients with ISCI, which either psychotherapy or routine rehabilitation therapy can not substitute.

To determine the effect of 7 days tactile kinesthetic stimulation (TKS) on preterm infants' weight and hospital stays in Khartoum State, Sudan. This is a quasi-experimental study, it was conducted in 4 hospitals between January and June 2013, Khartoum, Sudan, and it involved 160 preterm infants randomly assigned into the case and control groups (80 neonates in each). Preterm infants in the control group received routine nursing care, while preterm infants in the case group received TKS for 3 periods, 15 minute per day for 7 constitutive days, in addition to routine care. Data was collected using a structured self-designed and validated questionnaire, checklist, and weighting scale. Weight gain and hospital stay were compared between the 2 groups. Over the constitutive 7 days, the case group gained significantly more weight (1071 gm versus 1104 gm) compared with the control group (1077 gm versus 1084 gm) (1084.55±90.74) who gained only 6.9 gm within the same 7 days without TKS treatment. The mean difference in weight gain was significant (p=0.00). The hospital stay for preterm infants in the case group was significantly shorter (18.05±9.36 versus 25.47±10.25; p=0.00). Tactile kinesthetic stimulation for preterm infants has a beneficial effect on weight gain and earlier discharge from hospital, which are sequentially efficient and cost effective.

To compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD. One hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately. Three cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group. The combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

We evaluated the usefulness of pulmonary surfactant protein A (SP-A) as a practical diagnostic marker of fatal mechanical asphyxia in forensic autopsy cases. A total of 27 cases of asphyxia were examined histologically and immunohistochemically and compared with a control group consisting of 16 cases of poisoning (n = 9) and peracute death (n = 7). Both groups showed histological findings of local atelectasis and local emphysema, congestion, intra-alveolar and interstitial edema in most cases and pulmonary hemorrhages in some cases. The mechanical asphyxia group showed a significantly increased intensity of SP-A staining in the intra-alveolar space accompanied by many massive aggregates in approximately 60% of cases, which was not found in the control group. These structures may be interpreted as aggregates of pulmonary surfactant released from the alveolar wall due to enhanced secretion caused by strong forced breathing or over-excitement of the autonomic nervous system by mechanical asphyxia. The results of our investigation suggest the practical usefulness of the immunohistochemical detection of SP-A in distinguishing mechanical asphyxia from other types of hypoxia.

Background: Harvey-Ras (H-Ras) is an important guanosine triphosphatase protein for the regulation of cellular growth and survival. Altered Ras signaling has been observed in different types of cancer either by gene amplification and/or mutation. The H-Ras oncogene mutations are well reported, but expression of the H-Ras gene is still unknown. Objective: This study aimed to examine both protein and messenger-RNA (mRNA) expressions of H-Ras in oral squamous cell carcinoma (OSCC) and analyzed the association with risk habits and the clinicopathological profile of cases. Methodology: A total of 65 tissue specimens of OSCC (case group) and equal number of normal tissues (control group) were included in this study. H-Ras protein and mRNA expressions were analyzed using immunohistochemical and quantitative real time-polymerase chain reaction techniques, respectively. Results: The H-Ras protein was significantly overexpressed in the oral carcinoma group compared to the normal group (P = 0.03). Most of the OSCC cases showed positive staining with moderate expression, while negative and moderate staining was high in the control group. The majority of H-Ras positive cases were found in individuals with multiple risk habits including tobacco chewing. The risk of H-Ras positivity was 1.46 times higher in smokers than non-smokers. H-Ras positivity increased in cases affected with buccal mucosa site and higher grade of carcinoma. Relative mRNA level of H-Ras was significantly elevated in oral carcinoma as compared with the control group (P ≤ 0.001). Protein and mRNA levels of H-Ras in case group was poorly correlated. Conclusion: H-Ras oncogene expression was markedly higher in oral carcinoma, and it can be a prognostic marker and target for an effective molecular therapy. PMID:29731559

Objective Recurrent pregnancy loss (RPL) is a heterogeneous disease which is defined as two or more consecutive fetal losses during early pregnancy. Interleukin-1 receptor antagonist (IL-1Ra) is a anti-inflammatory cytokine, which inhibits IL-1 activity by binding to its receptors. The aim of this study was to investigate the association between RPL and IL-1Ra intron 2 polymorphism (86 bp VNTR) in Iranian women. Materials and methods In this case control study, genetic polymorphism was studied in 140 RPL patients and 140 healthy women as controls. Genomic DNA was extracted from the blood samples and polymorphism analysis was performed using the polymerase chain reaction (PCR) method. Finally, the data obtained were analyzed by statistical software. Results We found an increased frequency of the IL-1Ra 1/1 genotype in the case group compared to the control group. Whereas, the frequency of IL-1Ra genotype 1/2 was higher in control group than in the case group. However, we did not observe an association between IL-1Ra 86 bp VNTR polymorphism in intron 2 and RPL patients (p > 0.05). Conclusion IL-1Ra VNTR polymorphism may not be a genetic factor for RPL. However, investigation of IL-1Ra polymorphism was recommended in other populations and patients with recurrent pregnancy loss.

The strongest environmental factors identified for ulcerative colitis (UC) are cigarette smoking and appendectomy. However, most studies have been performed using case-controls from hospital-based populations. The purpose of this study was to compare the history of previous appendectomy and smoking habits in a group of patients with UC and a control group, followed by gastroenterologists in private practice. We performed a case control study in which 100 physicians recruited UC-patients and age and sex matched controls. Data were collected during a single visit. Based on a standardized questionnaire, UC patients and controls were divided into never, former or current smokers, and into subjects with or without a previous history of appendectomy. One hundred and ninety eight age- and sex-matched pairs of UC patients and controls were included. The prevalence of appendectomy in the UC-patients and control group was 12% and 46%, respectively. The pairwise-matched OR of ulcerative colitis for previous appendectomy was 0.10 (95% CI, 0.05-0.21) (P<0.0001). The OR for former and never smokers versus current smokers was 2.40 (95% CI 1.31-4.38) (P=0.004). In UC-patients, the OR of family history of UC compared with controls was 2.80 (95% CI, 1.01-7.77) (P=0.048). This case-control study confirmed a strong negative correlation between both appendectomy and tobacco smoking, and ulcerative colitis in patients followed-up by gastroenterological practitioners.

In a clinical trial carried out on 60 women with multiple sclerosis, the researchers obtained data using survey questionnaires. In addition to demographic data, the Multiple Sclerosis Quality of Life-54 (MSQoL-54) instrument was used to determine how multiple sclerosis influences the quality of life of the studied women. Within the frame of this randomized controlled trial, the participants were divided into two equally sized groups (the case and the control group) in which the level of pain and the quality of life were evaluated. The case group exercised pain-managing Yoga methods for three months, keeping the pace of eight 90-minute sessions per month. The control participants were subjected to no intervention. One month after the Yoga therapy, the level of pain and the quality of life were evaluated in both groups and compared to the baseline data. Data were analyzed using SPSS software and paired t-tests. After the Yoga therapy, the case group showed a significant improvement in physical pain management (P=0.007) and the quality of life (P=0.001) as compared to the control group. The results showed that Yoga techniques can alleviate physical pain and improve the quality of life of multiple sclerosis patients.

To discuss the effect of preemptive analgesia with parecoxib sodium in patients undergoing radical resection of lung cancer. 115 cases of lung cancer patients with American society of anesthesiologists class (ASA) grade I~II who received selective operation were randomly divided into the research group and the control group. The research group patients were given preoperative parecoxib sodium 40 mg plus postoperative normal saline 2 ml, while the control group patients were treated with preoperative normal saline 2 ml plus postoperative parecoxib sodium 40 mg. The pain condition at postoperative 1, 2, 4, 8, 12, 24 and 48 h were evaluated by visual analogue scale (VAS), and emergence agitation was tested by agitation score. Finally there were 56 cases and 57 cases can be used for evaluation in the research group and control group. The VAS scores after 1, 2, 4, 8, 12, 24 and 48 h in the research group and control group were [2.23±0.45, 2.35±0.48, 2.51±0.51, 2.41±0.45, 2.28±0.42, 2.16±0.39, 2.11±0.40] and [3.80±0.62, 4.01±0.64, 4.31±0.67, 4.10±0.64, 3.65±0.70, 3.12±0.66, 2.46±0.53], respectively. The research group were obviously lower than the control group, the difference were statistically significant (P<0.05). The rate of agitation was 24.44% (11/56) in the research group, significantly lower than the control group of 59.65% (34/57) (P<0.05). Preemptive analgesia with parecoxib sodium can obviously relieve acute pain using in patients undergoing radical resection of lung cancer, and is helpful to reduce the incidence of emergence agitation.

86 cases of acne vulgaris were treated with Fu Fang She She Cao He Ji ([symbol: see text] Compound Oldenlandis Mixture), with the other 34 cases treated with Dang Gui Ku Shen Wan ([symbol: see text] Pills Prepared from Chinese Angelica and Flavescent Sophora Root) as the controls, to observe the therapeutic effect of the former. The results showed that the cure plus markedly effective rate was 73.26% in the treatment group, and 47.06% in the control group, with a significant difference in the cure plus markedly effective rate between the two groups (P < 0.01), and also in the total effective rate between the two groups significant (P < 0.05). It may be concluded that the Compound Oldenlandis Mixture is a better agent for the illness.

To assess the effect of experienced stigma on depth of multidimensional poverty of persons with severe mental illness (PSMI) in Delhi, India, controlling for gender, age and caste. Matching case (hospital)-control (population) study. University Hospital (cases) and National Capital Region (controls), India. A case-control study was conducted from November 2011 to June 2012. 647 cases diagnosed with schizophrenia or affective disorders were recruited and 647 individuals of same age, sex and location of residence were matched as controls at a ratio of 1:2:1. Individuals who refused consent or provided incomplete interview were excluded. Higher risk of poverty due to stigma among PSMI. 38.5% of PSMI compared with 22.2% of controls were found poor on six dimensions or more. The difference in multidimensional poverty index was 69% between groups with employment and income of the main contributors. Multidimensional poverty was strongly associated with stigma (OR 2.60, 95% CI 1.27 to 5.31), scheduled castes/scheduled tribes/other backward castes (2.39, 1.39 to 4.08), mental illness (2.07, 1.25 to 3.41) and female gender (1.87, 1.36 to 2.58). A significant interaction between stigma, mental illness and gender or caste indicates female PSMI or PSMI from 'lower castes' were more likely to be poor due to stigma than male controls (p<0.001) or controls from other castes (p<0.001). Public stigma and multidimensional poverty linked to SMI are pervasive and intertwined. In particular for low caste and women, it is a strong predictor of poverty. Exclusion from employment linked to negative attitudes and lack of income are the highest contributors to multidimensional poverty, increasing the burden for the family. Mental health professionals need to be aware of and address these issues. Published by the BMJ Publishing Group Limited.

Tavakolizadeh, Jahanshir; Moghadas, Mehri; Ashraf, Hami
2014-01-01
Background: Diabetes is the most common metabolic disorder which is required to be taken under control. According to some studies, the impact of self-regulation on health has been considered as a monitoring strategy to achieve individual’s goals. Objectives: This study, which was performed in 2012, aimed at determining the consequences of self-regulation on controlling type 2 diabetes. Patients and Methods: In this double-blind clinical trial, 60 patients with type 2 diabetes - who were referred to Diabetes Clinic of Bisto-Dou Bahman Hospital in Gonabad, Iran - were divided randomly into case and control groups. Self-regulation questionnaire, nutritional information and physical activity checklists were completed by both groups once at the beginning and once at end of the training. Fasting blood sugar (FBS) of both groups were measured as well. Case group was trained for a month, whereas the control group received no special training. Data were analyzed by SPSS version 19 software, K-square and paired t-tests. Results: Comparing the case with the control group before and after the training showed that teaching patients self-regulatory strategies had significant impact on lowering blood sugar (-16.50 vs. -2.47, P < 0.001), observing dietary behaviors (5.97 vs. -0.87, P < 0.001) and increasing physical activities (6.2 vs. -0.73, P < 0.001) of the former group. Conclusions: Learning self-regulations has a role to play in controlling type 2 diabetes. Therefore, it is suggested to professionals in healthcare centers to educate patients about self-regulatory techniques and use them as auxiliary methods for keeping type 2 diabetes under control.

In Iran, after unintentional accidents, mental health problems are the second leading burden of disease. Consanguineous marriage is very common in Iran and the association between parental consanguinity and mental health is an important issue that has not yet been studied sufficiently in Iran. To investigate the effect of consanguinity and the degree of relationship on different levels of mental health. In this cross-sectional study, conducted in the Shahrekord University of Medical Sciences, two groups of students were enrolled. The first group consisted of 156 students that had consanguineous parent (case group) and the second group was 156 students whose parents had non-blood relationship (control group). The students were evaluated using General Health Questionnaire (GHQ-28). Statistical analysis was conducted by Pearson's correlation coefficient, independent t-test and the one-way analysis of variance. Odd ratio was used to estimate the relative risk. Over 30% of the individuals were suffering from mental health problems. The most and least common mental health problems in both groups were social dysfunction (54.5% in the case group and the control group 50%) and depression (15.4% in the case group and 17.3% in the control group), respectively. No statistically significant difference was observed in the frequency of overall mental health and its subscales between student with non-consanguineous parent (control group) and the students that had consanguineous parent (case group) (p>0.05) and the status of mental health was not significantly different among student with different degree of kinship (p>0.05). The study revealed that social dysfunction was very common among the study students and also there were no relationship between parental consanguineous marriage and mental health. Parental consanguinity and genetic factors may not be the major causes of high prevalence of mental health problems in Iran and the effects of the environmental factors on these problems may be greater than those of the inherited ones.

Objective: To determine the frequency of Helicobacter pylori (H. pylori) infection in diabetic and non-diabetic patients and to compare the frequency of H. pylori infection in both groups. Study Design: Case control. Place and Duration: Department of Medicine, Liaquat University Hospital from October 2007 to March 2008. Materials and Methods: This hospital-based case-control study was conducted on 148 subjects and divided into two groups i.e. type 2 diabetics and non-diabetics; each group consisting of 74 patients. All diabetic patients of ≥ 35 years of age, both gender and the known cases with history of dyspepsia, epigastric pain or bloating for more than a month were screened for Helicobacter pylori infection. The collected data of both groups was evaluated and separated for analysis. Results: Majority of the patients were male with mean age ± SD, 52.86 ± 8.51. Among the diabetic group, HpSA was positive in 54/74 (73%), whereas in the non-diabetic group HpSA was positive in 38/74 (51.4%) cases. Fasting blood glucose was identified as low in 04 (5.40%) H. pylori infected - diabetic patients where as the blood glucose level of 07 (9.45%) known diabetic patients was raised despite the ongoing medication. Conclusion: Diabetic patients are more prone and at risk to acquire H. Pylori infection. Therefore proper monitoring of blood glucose level and screening for H. pylori infection are effective preventive measures for this life threatening infection. PMID:20431802

To evaluate the effect of pre-operative indomethacin suppository on postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy. A double blind placebo-controlled randomized clinical trial. Hazrat Rasoul Akram Hospital, Tehran, Iran, from February 2010 to September 2012. One hundred and thirty patients, scheduled for laparoscopic cholecystectomy, were randomly divided into case and control groups. Sixty-five patients received indomethacin suppository and 70 patients received rectal placebo in the case and control groups respectively. All patients underwent the same protocol in laparoscopic surgery and anesthesia, then nausea and vomiting was recorded after 1, 6, 12 and 24 hours postoperatively and compared between the two groups. Independent-sample t test or Mann-Whitney tests were used for statistical analysis. Level of statistical significance was set at P ² 0.05. Patients' nausea was statistically lower in the case group at the 1st hour (43.1 vs. 92.9%), 6th hour (20.0 vs. 68.6%) and 12th hour (7.7 vs. 24.3%) after surgery (for all periods, P < 0.001). Fewer patients in the case group experienced vomiting at the first (13.8 vs. 51.4%) and 6th hour (0 vs. 20%) after surgery (for both P < 0.001). The use of pethidine was also statistically less in the case group in the same hours after surgery (for all of them, P < 0.001). Rectal indomethacin before laparoscopic cholecystectomy led to lower postoperative nausea and vomiting.

A group of patients with idiopathic pulmonary fibrosis (IPF) presents with disease affecting one lung markedly more than the other. At this time, it is unclear how this population differs from those who present with more symmetric disease. We sought to explain the characteristics of the asymmetric group and how their disease progresses. In this retrospective case-control study we accessed an interstitial lung disease (ILD) database and identified 14 asymmetric IPF cases via high-resolution computed tomography (HRCT) scoring of each lung lobe's disease severity. We identified 28 symmetric IPF controls from the same database using the same methods, and compared the clinical features of each group. Patients with asymmetric disease exhibited similar demographics as those in the general IPF population; they were predominantly male (64%), elderly (69 years old), and used tobacco (57%). We found a trend toward significantly increased all-cause mortality in the case population two years following diagnosis (p = 0.089). Pulmonary function tests were significantly lower in the case group at the time of diagnosis, then both groups experienced gradual decline. We found no statistically significant differences in number of IPF exacerbations (cases 43%, controls 39%, p = 0.824) and gastro-esophageal reflux (both groups 50%). Patients with asymmetric IPF resemble patients in the general IPF population but may have a lower overall survival rate. Further systemic factors may be studied to identify reasons for disease asymmetry and clinical decline in this population. Published by Elsevier Ltd.

To explore the growth pattern of appropriate for gestational age (AGA) infants of mother with gestational diabetes mellitus (GDM). The objects of this study were offspring of women who delivered in our hospital from January to December 2011. The GDM group included 70 AGA infants (36 male cases and 34 female cases) of mother with GDM. The control group included 154 AGA infants (66 male cases and 88 female cases) of women with normal glucose tolerance. The data of demographic characteristics of mothers of two groups were collected. Body weight and length of infants in two groups were measured at 3, 6 and 12 months age respectively. Body mass index (BMI), weight and height gain during infancy (0-3 months, 3-6 months and 6-12 months) of infants in two groups were also calculated. Body weight, length and BMI of male AGA infants in GDM group were less than that of control group at 3 months and 6 months age, but more than that of control group at 12 months age, however, there were no significant differences between two group(P>0.05). The weight and height gain during infancy (0-3 months, 3-6 months) of male AGA infants in GDM group were lower than that of control group, but the difference was statistically significant only at 3-6 months[(1.1±0.4) vs (1.4±0.4) kg, P=0.040; (4.9±2.3) vs (6.3±1.2) cm, P=0.026]. The weight and height gain during infancy (6-12 months) of male AGA infants of gestational diabetic mothers were higher than that of control group, but the difference was not statistically significant[(2.1±0.5) vs (1.8±0.5) kg, P=0.361; (8.4±1.3) vs (7.8±1.4) cm, P=0.464]. Male infants of gestational diabetic mothers grew slowly during their infancy of 0-6 months, and then their growth became increasingly fast, which suggested that the influence of intrauterine hyperglycemia environment of GDM mothers on fetal growth might continue after birth.

Both tuberculosis cervical lymphadenitis (TCL) and oropharyngeal tularaemia (OT) have similar signs, symptoms and pathological findings. We aimed to investigate the frequency of tularaemia antibodies in patients diagnosed with TCL. Using data from the Tuberculosis Control Dispensaries between the years of 2008 and 2011 in Turkey, all patients diagnosed with TCL were informed about and included in the study. Control group subjects were selected from healthy blood donors who lived in the same region. After informed consent was obtained, the sera obtained from volunteer TCL patients and the control group were tested with a microagglutination technique for Francisella tularensis. Antibodies to Brucella were also investigated with a tube agglutination test for cross-reactivity in sera that were seropositive for tularaemia. Sera were obtained from a total of 1170 individuals in the TCL group and 596 in the control group from 67 of 81 provinces in Turkey. Francisella tularensis-positive antibodies were found in 79 (6.75%) cases in the TCL group and two (0.33%) cases in the control group with a titre of ≥1:80 (p < 0.01). When the presence of antibody of any titre was considered, the ratio became 8.2% (96/1170) in the TCL group and 0.67% (4/596) in the control group (p < 0.001). For the first time, with this study, tularaemia serology was found to be positive in a significant portion (6.75%) of diagnosed cases of TCL. In tularaemia endemic regions, it was concluded that tularaemia serology should be investigated in patients suspected of having TCL. © 2012 The Authors Clinical Microbiology and Infection © 2012 European Society of Clinical Microbiology and Infectious Diseases.

Bronchiolitis has been known to be among the main the pathological features of lung lesions in Mustard Gas (MG) exposed patients. The purpose of this research was to evaluate the efficacy of interferon gamma-1b on the lung function in MG exposed patients with bronchiolitis. Thirty-six bronchiolitis patients, whose lung lesion had been diagnosed through High Resolution Computerized Tomography (HRCT) of the chest and also pathological study, were divided into two 18-member case and control groups. Both groups were receiving their conventional treatment (inhaled Felixotide and Servent). The case group were treated for 6 months with a combination of 200 microg of interferon gamma-1b (given three times per week subcutaneously) plus 7.5 mg of prednisolone (given once a day), while the control group received their previous conventional medications. Lung function was measured at base line and after 1, 3 and 6 months of treatment. In case and control groups, Forced Expiratory Volume in first second (FEV1) did not have statistical differences at the base line (49.3 +/- 2.9 and 48.7 +/- 4.1, respectively = 0.6), whereas a significant increase was seen in the case group (66.3 +/- 5.4) compared control group (57.3 +/- 8.6) at the subsequent months (P = 0.001 for the difference between the groups). Similar pattern of increase was observed in Forced Vital Capacity (FVC). The findings of this study indicate that a 6-month treatment with interferon gamma-1b plus a low-dose prednisolone is associated with an improvement in the lung function in mustard-gas exposed patients with bronchiolitis.

Do symptomatic female office workers perform computing tasks with higher cervical postural muscle loads (in terms of higher amplitudes and less muscular rest) and more discomfort compared with asymptomatic individuals? Are these differences in postural muscle loads consistent across bilateral (typing) and unilateral (mousing) conditions? an experimental case-control study. 18 symptomatic female office workers and 21 asymptomatic female office workers. Three conditions (typing, mousing, and type-and-mouse) were performed in random order. Muscle load was measured as median amplitude and gap frequency using surface EMG of bilateral cervical erector spinae and upper trapezius. Discomfort was measured using a numerical rating scale. The case group demonstrated 4.3% (95% CI 0.1 to 8.4) higher amplitude during typing and 3.5% (95% CI 0.1 to 6.9) higher amplitude during type-and-mouse in the right cervical erector spinae compared with the control group. There was a similar difference between groups in the left cervical erector spinae which also demonstrated a 1.2 gaps/min (95% CI -2.3 to 0.0) lower frequency during typing. The case group had significantly higher discomfort during all conditions compared with the control group. The case group demonstrated higher median amplitudes and lower gap frequencies than the control group during bilateral conditions (typing and type-and-mouse) compared with unilateral conditions (mousing) for both muscle groups. There was increased amplitude and decreased muscular rest in the cervical erector spinae of office workers performing typing and mousing tasks. These findings may represent a mechanism underlying computer-related musculoskeletal disorders.

Research on how the risk of gastric cancer increases with Epstein-Barr virus (EBV) infection is lacking. In a systematic review that investigated studies published until September 2014, the authors did not calculate the summary odds ratio (SOR) due to heterogeneity across studies. Therefore, we include here additional studies published until October 2015 and conduct a meta-analysis with meta-regression that controls for the heterogeneity among studies. Using the studies selected in the previously published systematic review, we formulated lists of references, cited articles, and related articles provided by PubMed. From the lists, only case-control studies that detected EBV in tissue samples were selected. In order to control for the heterogeneity among studies, subgroup analysis and meta-regression were performed. In the 33 case-control results with adjacent non-cancer tissue, the total number of test samples in the case and control groups was 5280 and 4962, respectively. In the 14 case-control results with normal tissue, the total number of test samples in case and control groups was 1393 and 945, respectively. Upon meta-regression, the type of control tissue was found to be a statistically significant variable with regard to heterogeneity. When the control tissue was normal tissue of healthy individuals, the SOR was 3.41 (95% CI, 1.78 to 6.51; I-squared, 65.5%). The results of the present study support the argument that EBV infection increases the risk of gastric cancer. In the future, age-matched and sex-matched case-control studies should be conducted.

Adequate bleeding control is essential for the success of periapical surgery. The aim of this study was to evaluate the effects of 2 hemostatic agents on the outcome of periapical surgery and their relationship with patient and teeth parameters. A prospective study was designed with 2 randomized parallel groups, depending on the hemostatic agent used: gauze impregnated in epinephrine (epinephrine group) and aluminum chloride (aluminum chloride group). The analysis of the hemorrhage control was judged before and after the application of the hemostatic agents by the surgeon, and 2 examiners independently recorded it as adequate (complete hemorrhage control) or inadequate (incomplete hemorrhage control). Ninety-nine patients with a periradicular lesion were enrolled in this study and divided into 2 groups: gauze impregnated in epinephrine in 48 patients (epinephrine group) or aluminum chloride in 51 (aluminum chloride group). In epinephrine group adequate hemostasis was achieved in 25 cases, and in aluminum chloride group it was achieved in 37 cases (P < .05). The outcome was better in the aluminum chloride group than in the gauze impregnated in epinephrine group. Copyright © 2016 American Association of Endodontists. Published by Elsevier Inc.

The human papilloma virus (HPV) can play a role in the development of head and neck squamous cell carcinoma (SCC). Our aim was to assess the prevalence of HPV DNA in SCC of the larynx. The impact of HPV infection on patient survival was also evaluated. This case-control study was performed in 44 patients with SCC of the larynx (case group), while the control group comprised samples obtained from cadavers with no previous history of malignancy. A preliminary pathologic evaluation was performed on all samples in the control group (36 samples) to ensure the absence of dysplasia or malignancy. Polymerase chain reaction (PCR) was used to detect HPV DNA. After completing the treatment protocol, patients were followed to assess the impact of HPV infection on overall survival (OS). PCR evaluation in the case group showed that HPV DNA was successfully isolated from 11 (25%) samples, while only two (5.6%) HPV DNA-positive were obtained from cadavers. According to these results, a significant difference was obtained in the prevalence of HPV DNA and laryngeal SCC between cases and controls (P=0.031). No statistically significant difference was observed in the OS of patients with or without HPV infection in the case group (P=0.235). Based on these results, we suggest that the prevalence of HPV infection is higher in laryngeal SCC subjects compared with healthy individuals. Although a longer OS was seen in HPV-positive patients, survival analysis did not show a significant difference in the comparison of HPV-positive and negative findings in SCC patients.

Intestinal parasites usually create benign diseases, though they may induce complications with high morbidity and mortality to the immunocompromised, including diabetic patients. The study detected the prevalence of intestinal parasitic infections in diabetic patients, comparing to non-diabetic controls and other parameters. A total of 100 fecal samples were collected from diabetic patients at the outpatient clinic of Sohag University Hospitals and another 100 from cross matched controls. The samples were examined macroscopically and microscopically by direct smear and different concentration methods then stained by Modified Ziehl-Neelsen Acid fast stain. Glycated hemoglobin (Hb Alc) was measured to detect DM controlled patients. The data were organized, tabulated, and statistically analyzed. Intestinal parasites were found in 25 (25%) cases out of 100 patients in diabetic group and 7(7%) cases out of 100 controls with high significance (P<0.001)). In the diabetic group, Giardia lamblia was detected in 22 cases (22%) and 5 (5%) among controls, Entamoeba histolytica in 7 cases (7%) and 3 (3%) among controls, Hymenolypis nana in 5 cases (5%) and 3 (3%) among controls, Entamoeba coli in 8 patients (8%), Entamoeba hartmanni in 3 cases (3%), Dientamoeba fragilis in a case (1%), Cryptosporidium parvum in 5 cases (5%) and microsporidia in 3 cases (3%). But, E. coli, E. hartmanni, D. fragilis and C. parvum nor microsporidia were detected in controls. The rate of G. lamblia in DM patients compared to controls was high significant (P<0.001). Hymenolepis nana was 5% (5 cases) in diabetic patients compared to 3% (3 cases) in controls. Residence and sex differences were not significant, while age, >10 years showed the highest prevalence (P< 0.003), type I infection rate was significantly higher than type II (P<0.001). DM control was also significantly affected the infection rates (P<0.007 in type I and P< 0.01 in type II).

The relationship between bile acid reflux into the stomach and the risk of atrophic gastritis and intestinal metaplasia is still not well understood. Towards obtaining a better understanding, concentrations of bile acids were measured. This study was carried out with the participation of 14 facilities in Japan, and 2283 samples were collected. The subjects with bile acid concentrations equal to or higher than the limit of detection were divided into four groups of equal size (group A: 0-25%, group B: 26-50%, group C: 51-75%, and group D: 76-100%). Thus, including the control group, there were five groups in total. The odds that the control group would develop atrophic gastritis and intestinal metaplasia was set as 1,and the odds ratios (OR) in groups A, B, C and D were calculated based on the odds in the control group. Regarding the development of atrophic gastritis, no increased risk was observed in either the Helicobacter pylori (H. pylori)-positive or -negative cases. The OR for the development of intestinal metaplasia were significantly higher, for both cases with and without H. pylori infection, in group D. High concentrations of bile acid seem to be associated with an elevated risk of intestinal metaplasia. © 2013 The Authors. Digestive Endoscopy © 2013 Japan Gastroenterological Endoscopy Society.

To observe the expression of phosphatase and tensin homology deleted on chromosome ten (PTEN) in myocardial tissue in patients with coronary heart disease, and explore the relevance between the expression of PTEN and the occurrence and development of coronary heart disease. A total of 16 death cases with pathological diagnosis of coronary heart disease were collected as experimental group, and 19 cases without myocardial lesions were selected as control group. The expression of PTEN protein and its mRNA were detected by immunohistochemistry and real-time fluorescence quantitative PCR respectively. The correlation between the expression of PTEN and the pathogenesis of coronary heart disease was analyzed. The expression of PTEN protein in myocardium in cases with coronary heart disease was significantly lower compared with the control group (P < 0.05). There was no statistical difference of the expression of PTEN mRNA between experimental and control group (P > 0.05). PTEN may be involved in the occurrence and development of coronary heart disease.

To investigate whether the concomitant presence of anterior cervical osteophytes can influence the severity and outcome of patients with poststroke dysphagia. Retrospective case-control study. Hospital. A total of 40 participants were identified (N=40). Patients with poststroke dysphagia with anterior cervical osteophytes (n=20) were identified and matched by age, sex, location, and laterality of the stroke lesion to a poststroke dysphagia control group with no anterior cervical osteophytes (n=20). Not applicable. Videofluoroscopic swallowing study, Functional Oral Intake Scale (FOIS), and Penetration-Aspiration Scale results assessed within the first month of stroke were analyzed. The FOIS at 6 months was recorded, and severity of dysphagia was compared between the 2 groups. The case group had larger degrees of postswallow residues in the valleculae and pyriform sinuses (P=.020 and P<.001, respectively), with more patients showing postswallow aspiration (62.5%) than the control group (0%; P<.001), along with a higher risk of being on enteral nutrition feeding (odds ratio [OR]=13.933; 95% confidence interval [CI], 2.863-infinity) within the first month of stroke. At the 6-month follow-up, the case group had significantly lower mean FOIS scores (3.8±1.7) than the control group (6.1±1.3; P<.001), with an increased risk of having persistent dysphagia (OR=15.375; 95% CI, 3.195-infinity). The presence of anterior cervical osteophytes, which may cause mechanical obstruction and interfere with residue clearance at the valleculae and pyriform sinuses and result in more postswallow aspiration, may influence initial severity and outcome of poststroke dysphagia. The presence of anterior cervical osteophytes may be considered an important clinical condition that may affect poststroke dysphagia rehabilitation.

Sexual difficulty has various effects on patients suffering from this condition that can impact on interpersonal and marital relationships. Sexual function may be adversely affected by stress of any kind and emotional disorders. There have been limited studies focusing on the mental health of those suffering from this problem. To determine the relationship between sexual difficulties and mental health in female patients seeking help in psychiatric clinics. The study was based on the case-control design methodology in which the case group consisted of 165 outpatients of two psychiatric clinics, who were diagnosed with different mental disorders such as depression, anxiety, phobia, aggression, and somatic complaints (33 subjects for each type of disorder). The 33 subjects in the control group were chosen among the patients' relatives and visitors who had no history of either seeking psychiatric help or taking psychiatric drugs. The subjects of both case and control groups were selected based on a convenience sampling method. Moreover, the data were collected based on two techniques of "interview" and "questionnaire;" the latter was of three different subcategories, each dealt with demographic characteristics, sexual difficulties, and a Symptom Check-List-90-Revised. Assessing female sexual difficulties associated with mental health and differences between women with and without psychiatric problems. The obtained results indicated that there was a significant difference between the prevalence of sexual difficulties (e.g., sexual desire and orgasm disorders) in the case group and that of the control group. It was also revealed that there was a significant difference between the depressed, aggressive, as well as those with somatic complaints, and their control group counterparts. In Iran, sexual difficulties seem to be more frequent in those seeking psychiatric help in clinics than in those within the normal population.

Objective We examined the impact of a combination of home environmental interventions and nurse case management services on total settled dust loadings and on allergen concentrations in the homes of asthmatic children. Methods Using a randomized longitudinal controlled trial study design, we randomly assigned homes of asthmatic children in Milwaukee to either a control (n=64) or an intervention (n=57) group. Control group homes received a visual assessment, education, bed/pillow dust mite encasings, and treatment of lead-based paint hazards. The intervention group received these same services plus nurse case management that included tailored, individual asthma action plans, provision of minor home repairs, home cleaning using special vacuuming and wet washing, and integrated pest management. Dust vacuum samples were collected from measured surface areas of floors in the TV room, kitchen, and child's bedroom at baseline and at three-, six-, and 12-month follow-up visits. Dust loading (mass per surface area) is a means of measuring total dust and the total amount of allergen present. Results For the intervention group, geometric mean dust loadings declined significantly from baseline (39 milligrams per square foot [mg/ft2]) to post-intervention (11 mg/ft2) (p<0.001). Baseline dust loading, treatment group, visit, and season were significant predictors of follow-up dust loadings. Mean post-intervention dust loadings were 72% higher in the control group. The total amount of allergen in settled house dust declined significantly following the intervention because total dust loading declined; the concentration of allergens in settled dust did not change significantly. Conclusion The combination of nurse case management and home environmental interventions promotes collaboration between health and housing professionals and is effective in reducing exposures to allergens in settled dust.

To estimate the association between spontaneous abortion and influenza vaccine receipt with a case-control study utilizing data from six health care organizations in the Vaccine Safety Datalink. Women aged 18-44 years with spontaneous abortion during the autumn of 2005 or 2006 were identified using International Classification of Diseases, 9th Revision, Clinical Modification codes. Cases of spontaneous abortion at 5-16 weeks of gestation were confirmed by medical record review; date of fetal demise was based on ultrasound information when available. Control group individuals with a live birth were individually matched to case group individuals by health care organization and date of last menstrual period (LMP). The primary exposure of interest was influenza vaccination during the 28 days preceding the date of spontaneous abortion of the matched pair. Conditional logistic regression models adjusted for maternal age, health care utilization, maternal diabetes, and parity. Our final analysis included 243 women with spontaneous abortion and 243 matched control group women; 82% of women with spontaneous abortion had ultrasound confirmation of fetal demise. Using clinical diagnosis and ultrasound data, the mean gestational age at fetal demise was 7.8 weeks. Mean ages at LMP of case group women and control group women were 31.7 and 29.3 years, respectively (P<.001). Sixteen women with spontaneous abortion (7%) and 15 (6%) matched control group women received influenza vaccine within the 28-day exposure window. There was no association between spontaneous abortion and influenza vaccination in the 28-day exposure window (adjusted matched odds ratio 1.23, 95% confidence interval 0.53-2.89; P=.63). There was no statistically significant increase in the risk of pregnancy loss in the 4 weeks after seasonal inactivated influenza vaccination. II.

Some factors have an important role in endometriosis pathogenesis; there is an immune cell that plays an important role in endometrial cells that have reflux. Woman with endometriosis experienced the cellular immune disorder. It is suspected that decrease of NK cell in the peritoneal fluid caused by its qualitative defect with CD107a expression as the best marker. The aim of this study was to compare expression of NK Cell activity with CD107a between awoman with endometriosis and non-endometriosis. A case-control study from March until July 2015 in Haji Adam Malik General Hospital. The case group was ectopic endometrial tissue block paraffin and control group was normal endometrial tissue block paraffin. This study included 23 patients in endometriosis group and control group respectively. A majority proportion of CD107a expression in endometriosis group was +1 (16 patients (69.6%)), while the control group was +3 (9 patients (39.1%)). Expression of NK cell activity with CD107a in patients with endometriosis was lower than the control group (p<0.05). It suggested that cellular immune factors may play a role in the pathogenesis of endometriosis.

To survey on the vaccination of varicella live attenuated vaccine among 4-17 children in Minhang District, and analyze the protective effect against varicella. We collected outbreak chickenpox cases reported from infectious disease report system and surveillance units in Minhang district from 1st May in 2012 to 30th Apr in 2013. The 1: 3 matched case-control study was conducted to questionnaire the legal guardian of the cases and control group, and calculate the protective effect and effective term of protection. The survey included vaccination, chickenpox exposure history, previous history of varicella illness, suffering from the symptoms of chickenpox, the vaccinations brand, etc. The criteria of accepted case were those healthy students who were in the same class with those chickenpox cases. The accepted matched controlling data were those children who were from the same class with outbreak chickenpox cases without varicelliform eruption, similar live condition, the closest house, the same gender, the closest age. This study investigated 390 cases of patients and the control group included 1 170 cases. Chi-square test was used to compare the vaccination of cases and controls, as well as the incidence of chickenpox vaccination different brands VarV, Mantel-Haenzel chi-square test was applied to compare the protective effect of the two groups. VarV overall vaccination rate was 68.3% (1 065/1 560), among them, the case group coverage was 45.1% (176/390), significantly lower than the control group (76.0% (889/1 170)) (χ² = 128.55, P < 0.01). The coverage in children of 4-10 years old group was 88.4% (375/424), significantly higher than the 11-17 years old group (60.7% (690/1 136)) (χ² = 109.40, P < 0.01). The overall protective effect of VarV was 78.10% (71.82%-82.98%).Vaccinated group incidence ratio was 16.5% (176/1 065), significantly lower than the unvaccinated group (43.2% (214/495)) (χ² = 128.55, P < 0.01). The chickenpox risk of the children who were vaccinated was lower than those who were not, and the OR (95%CI) was 0.22(0.17-0.28) . Proportion of the fever and the typical symptoms of varicella zoster were 26.1% (46/176), 8.0% (14/176) in the children vaccinated VarV, significantly lower than children without VarV vaccination history (54.7% (117/214) , 18.2% (39/214) ) (χ² values were 32.33 and 8.67, respectively. P values both <0.01). The varicella incidence was 17.4% (139/797) in children vaccinated domestic VarV, and it was 13.8% (37/268) in the group of imported VarV (χ² = 1.92, P = 0.184) . The average duration of effective protection period for domestic and imported VarV was (6.2 ± 2.7), (6.3 ± 3.4) years (F = 2.24, P = 0.136). The risk of varicella incidence and the proportion of fever or typical varicella zoster were lower in the one dose of VarV vaccinated; Effective protective effect was consistent in the children with domestic or imported VarV vaccination.

Hypothyroidism is associated with significant neurocognitive deficits because hypothyroidism prevents the brain from adequately sustaining the energy consuming processes needed for neurotransmission, memory, and other higher brain functions. Hence, the study was done to assess the cognitive functions of newly diagnosed subclinical and clinical hypothyroid patients by evoked response potential P300. 75 patients each of newly diagnosed subclinical and clinical hypothyroid patients attending endocrinology clinic and 75 healthy age and sex matched euthyroid controls were considered for the study. P300 was recorded with Record Medicare System Polyrite, Chandigarh using auditory "oddball paradigm". The data was analyzed using ANOVA followed by post Tukey's test. Newly diagnosed clinical hypothyroid patients showed a significant increase in P300 latency compared to control (P < 0.05) and subclinical cases (P < 0.01) while there was no significant difference between the P300 latency of subclinical cases and control group. Also, there was no significant difference in P300 amplitude among the three groups. P300 latency in case of newly diagnosed hypothyroid clinical cases is significantly increased compared to newly diagnosed subclinical cases and control.

Control groups in previous case-control studies of vaccine-preventable diseases have included people immune to disease. This study examines risk factors for measles acquisition among adults 20 to 49 years of age in Tianjin, China, and compares findings using measles IgG antibody-negative controls to all controls, both IgG-negative and IgG-positive. Measles cases were sampled from a disease registry, and controls were enrolled from community registries in Tianjin, China, 2011-2015. Through a best subsets selection procedure, we compared which variables were selected at different model sizes when using IgG-negative controls or all controls. We entered risk factors for measles in two separate logistic regression models: one with measles IgG-negative controls and the other with all controls. The study included 384 measles cases and 1,596 community controls (194 IgG-negative). Visiting a hospital was an important risk factor. For specialty hospitals, the odds ratio (OR) was 4.53 (95% confidence interval (CI): 1.28, 16.03) using IgG-negative controls, and OR = 5.27 (95% CI: 2.73, 10.18) using all controls. Variables, such as age or length of time in Tianjin, were differentially selected depending on the control group. Individuals living in Tianjin ≤3 years had 2.87 (95% CI: 1.46, 5.66) times greater odds of measles case status compared to all controls, but this relationship was not apparent for IgG-negative controls. We recommend that case-control studies examining risk factors for infectious diseases, particularly in the context of transmission dynamics, consider antibody-negative controls as the gold standard.

To explore the effect of the transcutaneous tracheostomy tube in patients with pneumothorax and its clinical value. A prospective randomized controlled trial was conducted. Thirty-two patients with pneumothorax admitted to Department of Critical Care Medicine of Harrison International Peace Hospital of Hebei Medical University from June 2010 to June 2014 were enrolled. The patients were divided into control group and observation group, with 16 cases in each group. Beside the treatment for primary disease, the patients in control group received thoracic close drainage with traditional silica gel tube as performed by thoracic surgeons, and those in observation group received thoracic close drainage with transcutaneous tracheostomy tube by intensive care doctors. The curative effect and complications of the two groups were observed. Compared with control group, the time from diagnosis to operation (minutes:8.00 ± 1.36 vs. 23.06 ± 3.83, t=14.790, P=0.000) and the operation time were significantly shortened (days:5.37 ± 1.02 vs. 7.31 ± 1.70, t=7.286, P=0.000), the frequency of drainage tube replacement (times: 0.18 ± 0.40 vs. 3.87 ± 1.14, t=12.128, P=0.000) and the times of repeated chest radiography (times:1.12 ± 0.34 vs. 2.93 ± 0.77, t=8.589, P=0.000) in observation group were significantly reduced, the length of hospital day was significantly shortened (days:8.30 ± 1.37 vs. 24.56 ± 5.62, t=17.289, P=0.000), the rates of dislocation of drainage tube (0 vs. 3 cases), obstruction of the tube (0 vs. 5 cases), and subcutaneous emphysema (3 vs. 16 cases) were reduced obviously, but there was no difference in incidence of incision infection (1 vs. 3 cases) and infection of thoracic cavity (0 vs. 2 cases). The usage of transcutaneous tracheostomy tube in patients with pneumothorax is safe and simple. Doctors in ICU can independently do this procedure, and its effect is positive.

We examined whether a 'hint' manoeuvre increases the time novice medical learners spend on reviewing a radiograph, thereby potentially increasing their interpretation accuracy. Senior year medical students were recruited into a randomised control, three-arm, multicentre trial. Students reviewed an online 50-case learning set that varied in degree of 'hint' intervention. The 'hint' was a dialogue box that appeared after a student submitted an answer, encouraging the student to re-evaluate their interpretation. The students in the control group received no hints. In the weak intervention group, students received 'hints' with 66% of their incorrect interpretations and 33% of those that were correct. In the strong intervention group, the incorrect interpretation hint frequency was 80%, whereas for correct responses it was 20%. All students completed a 20-case post-test immediately and 2 weeks after the 50 cases. The primary outcome was student performance on the immediate post-test, measured as the ability to discriminate between normal and abnormal films (dPrime). Secondary outcomes included the probability of considering the hint, time spent on learning cases and knowledge retention at 2 weeks. We enrolled 117 medical students from three sites into the three study groups: control (36), weak intervention (40) and strong intervention (41) groups. The mean (standard deviation) dPrime in the control, weak and strong groups were 0.4 (1.1), 0.7 (1.1) and 0.4 (0.9), respectively (P = 0.4). In the weak and strong groups, participants reconsidered answers in 556 of 1944 (28.6%) hinting opportunities, and those who reconsidered their answers spent a mean (95% confidence interval) of 13.9 (11.9, 16.0) seconds longer on each case. There were no significant differences in knowledge retention at 2 weeks between the groups (P = 0.2). Although the implemented hinting strategy did result in students spending more time considering a proportion of the cases, overall it was not effective in improving student performance. © John Wiley & Sons Ltd.

The causes of death of 144 Japanese autopsy cases during 1945-1975, who had been intravascularly injected with Thorotrast in life, were compared with those of non-Thorotrast-administered autopsy cases in the same age bracket, recorded in the Annals of Japanese Pathological Autopsy Cases during 1958-1973. This comparison revealed that the incidence of malignant hepatic tumors was more than 10 times higher in the Thorotrast-administered cases. The increase was attributable to an increased incidence of hemangioendothelioma and cholangiocarcinoma of the liver. The only significant increase of liver cirrhosis found to exist in the Thorotrast group occurred in the female cases. Some ofmore » the Thorotrast-administered cases were found to have developed myeloid leukemia and erythroleukemia. There was also a significant increase in the number of cases of aplastic anemia in the Thorotrast group, but clinically and pathologically these were atypical. Lymphatic leukemia was not observed. No significant difference was found in the incidence of either malignant lymphomas or osteosarcomas in the Thorotrast group and the controls. Lung cancer, on the other hand, showed a significantly higher incidence among the controls than among the Thorotrast-administered cases.« less

35 patients of Maturity onset diabetes mellitus having the complaints of polyurea polydypsia and polyphagia etc. have been selected. For the diagnosis of diabetes mellitus the fasting and 1st hour and 2nd hour post parandial blood sugar were estimated. Patients were classified into two groups. 20 patients were treated with powder of C. Tamal leaves in the dose of 2 TSF T. D. S. and 15 patients were treated with Inula racemosa in the dose of 1 TSF T. D. S. for the period of three months. The response was estimated on the parameter of Joslin's Clinica in C. Tamal group 50% cases were in good control. 33.33% were in fair control and 16.67% cases were in poor control. Inula racemosa treated group 100% cases were in good control. Thus it can be inferred that both of the drugs are useful in the treatment of Diabetes mellitus of Maturity onset. However, the response of Inula racemosa is better as compared to C. Tamala.

Background Understanding glioma etiology requires determining which environmental factors are associated with glioma. Upper Midwest Health Study case–control participant work histories collected 1995–1998 were evaluated for occupational associations with glioma. “Exposures of interest” from our study protocol comprise our a priori hypotheses. Materials and Methods Year-long or longer jobs for 1,973 participants were assigned Standard Occupational Classifications (SOC) and Standard Industrial Classifications (SIC). The analysis file includes 8,078 SIC- and SOC-coded jobs. For each individual, SAS 9.2 programs collated employment with identical SIC-SOC coding. Distributions of longest “total employment duration” (total years worked in jobs with identical industry and occupation codes, including multiple jobs, and non-consecutive jobs) were compared between cases and controls, using an industrial hygiene algorithm to group occupations. Results Longest employment duration was calculated for 780 cases and 1,156 controls. More case than control longest total employment duration was in the “engineer, architect” occupational group [16 cases, 10 controls, odds ratio (OR) 2.50, adjusted for age group, sex, age and education, 95% confidence interval (CI) 1.12–5.60]. Employment as a food processing worker [mostly butchers and meat cutters] was of borderline significance (27 cases, 21 controls, adjusted OR: 1.78, CI: 0.99–3.18). Conclusions Among our exposures of interest work as engineers or as butchers and meat cutters was associated with increased glioma risk. Significant associations could be due to chance, because of multiple comparisons, but similar findings have been reported for other glioma studies. Our results suggest some possible associations but by themselves could not provide conclusive evidence. PMID:22715102

To compare the clinical efficacy differences between medicinal vesiculation combined with quick cupping at Shenque (CV 8) and regular medication for allergic rhinitis with syndrome of yang deficiency. Eighty-two cases were randomly divided into an observation group (42 cases) and a control group (40 cases). The observation group was treated with medicinal vesiculation combined with quick cupping at Shenque (CV 8). The medicinal vesiculation was applied at Feishu (BL 13), Gaohuang (BL 43), Fengmen (BL 12), Mingmen (GV 4) on the dog days in the summer, one treatment on the 1st dog-day, 2nd dog-day and last dog-day respectively with an interval of 10 days between two treatments. Three treatments were taken as one course, and totally one course was given. The quick cupping was applied at Shenque (CV 8), once a day, ten treatments were taken as one course, and totally three courses was given. The control group was treated with oral administration of loratadine and nasal spray of budesonide. The loratadine was given 10 mg per time, once a day for continuous 14 days; budesonide was given once a day, ten treatments were taken as one course, and totally three courses was given. The clinical efficacy in two groups after treatment was observed, and the contents of immune globulin E (IgE), interleukin-4 (IL-4), interleukin-5 (IL-5) and tumor necrosis factor-α (TNF-α) in peripheral serum were measured before and after the treatments. Of all the 82 patients, 79 cases completed the treatment, and 1 patient in the observation group and 2 patients in the control group dropped out. The effective rate was 87.8% (36/41) in the observation group, which was superior to 78.9% (30/38) in the control group (P<0.05). After treatment, both groups effectively reduced the contents of IgE, IL-4, IL-5 and TNF-α, and the observation group had superior effect on reducing IgE and IL-4 to the control group (P<0.05). The medicinal vesiculation combined with quick cupping at Shenque (CV 8) have better effect for allergic rhinitis with syndrome of yang deficiency than oral administration of loratadine and nasal spray of budesonide.

Abstract Background: Caveolin 1 gene (CAV1) has been associated with insulin resistance, metabolic syndrome and hypertension in humans. Also, it has been related to high serum triglycerides in rodents, however there is little evidence of this relation in humans. Aim: To describe frequencies of common variations in CAV1 in adults with high serum triglycerides. Methods: A case-control study was carried out with adults from Colombian Caribbean Coast. A whole blood sample was employed to measure serum concentrations of triglycerides, glucose, total cholesterol and HDLc. Six common Single Nucleotide Polymorphism (SNP) in CAV1 were genotyped (rs926198, rs3779512, rs10270569, rs11773845, rs7804372 and rs1049337). Allelic and genotypic frequencies were determined by direct count and Hardy-Weinberg Equilibrium (HWE) was assessed. Case and control groups were compared with null-hypothesis tests. Results: A total of 220 cases and 220 controls were included. For rs3779512 an excess in homozygotes frequency was found within case group (40.4% (GG), 41.3% (GT) and 18.1% (TT); Fis=0.13, p=0.03). Another homozygotes excess among case group was found in rs7804372 (59.5% (TT), 32.3% (TA) and 8.2% (AA); Fis= 0.12, p= 0.04). In rs1049337, cases also showed an excess in homozygotes frequency (52.7% (CC), 35.0% (CT) and 12.3% (TT); Fis= 0.16, p= 0.01). Finally, for rs1049337 there were differences in genotype distribution between case and control groups (p <0.05). Conclusion: An increased frequency of homozygote genotypes was found in subjects with high serum triglycerides. These findings suggest that minor alleles for SNPs rs3779512, rs7804372 and rs1049337 might be associated to higher risk of hypertriglyceridemia. PMID:29662258

Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p < 0.001). The incidence of Candida esophagitis was more frequent in cases with CS compared to cases with corticosteroid treatment and healthy controls (p = 0.03). Histopathological findings and frequency of Helicobacter pylori based on pathology results did not vary between the three groups. It is possible that neither exogenous nor endogenous corticosteroid excess directly causes peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

To analyze the learning curve for cancer control from an initial 250 cases (Group I) and subsequent 250 cases (Group II) of robotic-assisted laparoscopic radical prostatectomy (RALP) performed by a single surgeon. Five hundred consecutive patients with clinically localized prostate cancer received RALP and were evaluated. Surgical parameters and perioperative complications were compared between the groups. Positive surgical margin (PSM) and biochemical recurrence (BCR) were assessed as cancer control outcomes. Patients in Group II had significantly more advanced prostate cancer than those in Group I (22.2% vs 14.2%, respectively, with Gleason score 8–10, P= 0.033; 12.8% vs 5.6%, respectively, with clinical stage T3, P= 0.017). The incidence of PSM in pT3 was decreased significantly from 49% in Group I to 32.6% in Group II. A meaningful trend was noted for a decreasing PSM rate with each consecutive group of 50 cases, including pT3 and high-risk patients. Neurovascular bundle (NVB) preservation was significantly influenced by the PSM in high-risk patients (84.1% in the preservation group vs 43.9% in the nonpreservation group). The 3-year, 5-year, and 7-year BCR-free survival rates were 79.2%, 75.3%, and 70.2%, respectively. In conclusion, the incidence of PSM in pT3 was decreased significantly after 250 cases. There was a trend in the surgical learning curve for decreasing PSM with each group of 50 cases. NVB preservation during RALP for the high-risk group is not suggested due to increasing PSM.

Medical masks are commonly used by sick individuals with influenza-like illness (ILI) to prevent spread of infections to others, but clinical efficacy data are absent. Determine whether medical mask use by sick individuals with ILI protects well contacts from related respiratory infections. 6 major hospitals in 2 districts of Beijing, China. Cluster randomised controlled trial. 245 index cases with ILI. Index cases with ILI were randomly allocated to medical mask (n=123) and control arms (n=122). Since 43 index cases in the control arm also used a mask during the study period, an as-treated post hoc analysis was performed by comparing outcomes among household members of index cases who used a mask (mask group) with household members of index cases who did not use a mask (no-mask group). Primary outcomes measured in household members were clinical respiratory illness, ILI and laboratory-confirmed viral respiratory infection. In an intention-to-treat analysis, rates of clinical respiratory illness (relative risk (RR) 0.61, 95% CI 0.18 to 2.13), ILI (RR 0.32, 95% CI 0.03 to 3.13) and laboratory-confirmed viral infections (RR 0.97, 95% CI 0.06 to 15.54) were consistently lower in the mask arm compared with control, although not statistically significant. A post hoc comparison between the mask versus no-mask groups showed a protective effect against clinical respiratory illness, but not against ILI and laboratory-confirmed viral respiratory infections. The study indicates a potential benefit of medical masks for source control, but is limited by small sample size and low secondary attack rates. Larger trials are needed to confirm efficacy of medical masks as source control. ACTRN12613000852752; Results. Published by the BMJ Publishing Group Limited.

Tumours of the central nervous system are the second most common group of childhood cancers in 0-14 year olds (24% of total cancers) and represent a major diagnostic group in 15-24 year olds. The pilot case-control study aimed to establish methodologies for a future comprehensive aetiological investigation among children and young adults. Eligible cases were newly diagnosed with an intracranial tumour of neuroepithelial tissue aged 0-24 years. The pilot recruited patients through Leeds and Manchester Principal Treatment Centres. Controls were drawn from general practice lists. Controls were frequency matched by age and gender. We interviewed 49 cases and 78 controls comprising 85% of the target sample size. Response rates were 52% for cases and 32% for controls. Completion of the questionnaire was successful, with a very small proportion of missing data being reported (5-10%). The age distribution of cases and controls was similar with around three-quarters of interviewed subjects aged 0-14. Half of cases and almost two-thirds of controls reported using a mobile phone with the majority starting between 10-14 years of age. Prevalence of breastfeeding was lower in cases than controls (Odds Ratio 0.4; 95% CI 0.2-1.2), whilst cases were more likely to be delivered by caesarean section (OR 1.6; 95% CI 0.6-4.4). Cases were significantly more likely to have a birthweight > 3.5 kg compared to controls. Cases were also more likely to come from a family with 3 or more siblings than controls (OR 3.0; 95% CI 0.7-13.6). The majority of participants (>80%) were in favour of taking either blood or saliva to aid molecular epidemiological research. Successful methods were established for identifying and recruiting a high proportion of case subjects, exploiting strong links with the clinical teams at the treatment centres. Control procedures proved more difficult to implement. However, working closely with national clinical and professional research networks will enable improved control identification and recruitment, with good prospects for collecting biological samples in the future.

Group sequential testing procedures have been proposed as an approach to conserving resources in biomarker validation studies. Previously, Koopmeiners and Feng (2011) derived the asymptotic properties of the sequential empirical positive predictive value (PPV) and negative predictive value curves, which summarize the predictive accuracy of a continuous marker, under case-control sampling. A limitation of their approach is that the prevalence can not be estimated from a case-control study and must be assumed known. In this manuscript, we consider group sequential testing of the predictive accuracy of a continuous biomarker with unknown prevalence. First, we develop asymptotic theory for the sequential empirical PPV and NPV curves when the prevalence must be estimated, rather than assumed known in a case-control study. We then discuss how our results can be combined with standard group sequential methods to develop group sequential testing procedures and bias-adjusted estimators for the PPV and NPV curve. The small sample properties of the proposed group sequential testing procedures and estimators are evaluated by simulation and we illustrate our approach in the context of a study to validate a novel biomarker for prostate cancer.

To evaluate efficacy and safety of Guaifenesin compound pseudoephedrine hydrochloride oral solution for the treatment of cough, expectoration, nasal congestion and runny nose in children. This was a prospective multicenter randomized single-blind, parallel-controlled clinical study. A total of 10 centers participated in this study, the actual number of cases in line with the program was 412, of whom 205 cases in trial group were treated with Guaifenesin compound pseudoephedrine hydrochloride oral solution, and 207 cases in control group with ambroxol hydrochloride oral solution, treatment of both groups persisted for 7 days. The improvement rate of each single symptom and the combined symptoms and the overall effective rate were compared between the two groups. The adverse drug reactions and compliance were assessed as well. The treatment of both groups showed efficacy. Except sputum stickiness, the improvement of all symptoms in trial group was superior to that in the control group on the 3rd day after treatment (P < 0.05) and except nasal congestion, the efficacy in all the other symptoms of trial group was better than that in the control group as well on the 7th day (P < 0.01). The improvement rate for combined symptoms of Guaifenesin compound pseudoephedrine hydrochloride oral solution was 82.9% and the overall efficacy rate was 89.3%. Guaifenesin compound Pseudoephedrine hydrochloride oral solution had higher compliance and its adverse event rate was merely 0.92%. Guaifenesin compound pseudoephedrine hydrochloride oral solution showed significant efficacy and safety in children for treatment of cough, expectoration, nasal congestion and runny nose caused by common cold or acute tracheobronchitis.

Shivering, a common intraoperative problem under spinal anesthesia increases the oxygen consumption considerably and is uncomfortable and distressing to the patient, anesthesiologist as well as surgeon. The present study was designed to explore the effectiveness of tramadol, clonidine and dexmedetomidine in the treatment of post spinal anesthesia shivering and to look for their adverse effects. This prospective, randomized, double blinded control study was done on 90 patients who developed shivering under spinal anesthesia. They were randomly allocated into three groups with Group T receiving tramadol 1mg.kg -1 , Group C getting clonidine 1mcg.kg -1 and Group D patients receiving dexmedetomidine 0.5mcg.kg -1 . The time taken to control shivering, recurrence rate, hemodynamic variables, sedation score and adverse effects were observed. Dexmedetomidine was faster in the control of shivering in 5.7±0.79minutes (min) whereas tramadol took 6.76±0.93min and clonidine was slower with 9.43±0.93min. The recurrence rate was much lower in the dexmedetomidine group with 3.3% than for clonidine (10%) and tramadol (23.3%) group. The sedation achieved with dexmedetomidine was better than clonidine and tramadol. The tramadol group had more cases of vomiting (four) and dexmedetomidine group had six cases of hypotension and two cases of bradycardia. Two of the clonidine patients encountered bradycardia and hypotension. Dexmedetomidine is better than tramadol and clonidine in the control of shivering because of its faster onset and less recurrence rate. Though complications are encountered in the dexmedetomidine group, they are treatable. Copyright © 2016 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

Comparison between Topical and Oral Tranexamic Acid in Management of Traumatic Hyphema
Jahadi Hosseini, Seyed Hamid Reza; Khalili, Mohammad Reza; Motallebi, Mahmoud
2014-01-01
Background: We sought to determine the efficacy of topical tranexamic acid (5%) in the management of traumatic hyphema. Methods: Thirty eyes with gross traumatic hyphema were enrolled in this study. The patients were treated with tranexamic acid (5%) eye drop every 6 hours for 5 days. The main outcome measures were best corrected visual acuity (BCVA), Intra-ocular pressure (IOP), day of clot absorption, and rate of rebleeding. These parameters were evaluated daily for 4 days and thereafter at the 8th and 14th days after treatment. The patients were also compared with two historical control groups of patients (80 eyes) with traumatic hyphema; the first control group was treated with oral placebo and the other group was treated with oral tranexamic acid at our department. Result: Prior to treatment, the mean logarithm of the minimum angle of resolution (logMAR) BCVA was 0.59±0.62. BCVA was increased to 0.08±0.14 at day 14 (P<0.001) and the mean IOP before treatment was 13.7±3.9 mm Hg, which was reduced to 11.4±1.8 mm Hg at day 14 (P=0.004). Rebleeding occurred in one (3.3%) patient on the 4th day post treatment. Comparison between the case group and the other two historical control groups with respect to the rebleeding rate demonstrated statistically significant differences between the case group and the first control group (P=0.008) but no statistically significant differences between the case group and the second control group (P=0.25). Conclusion: Topical tranexamic acid seems promising in the management of traumatic hyphema. However, the small sample size of the present study precludes the conclusion that topical tranexamic acid can replace the oral tranexamic acid. PMID:24753640

Background: Motor vehicle collisions (MVC) comprise a majority cause of referral to the emergency department (ED). A large proportion of MVC appear to be preventable, if more effective measures against driving after substance abuse can be implemented. Objective: This study was aimed to investigate the prevalence of substance abuse among drivers of MVC, following road traffic accidents (RTA). Materials and Methods: This case-control research was conducted from July to October 2007. One hundred MVC drivers admitted in the ED were included as the case group and 110 hospitalized patients, due to nontraumatic causes were used as controls. History of substances abused was obtained and urine samples were tested for opium in both groups. Finally the history and laboratory results of the groups were compared using SPSS 18. Results: Of the 100 patients in the case group, 39 (39%) were positive for substance abuse (100% males). On the other hand, 49 (44.5%) patients in the control group had positive history or laboratory findings of substance abuse (73.9% male). Opioids were the most common agent abused in both groups. There was no significant difference between two groups regarding the prevalence of substance abuse (P = 0.92). Conclusions: The prevalence of substance abuse is high among victims of road traffic injury but in equal proportion to the control group. Health education and counseling is needed to reduce substance abuse in the general population although it was not significantly related to the cause of RTA. PMID:24829889

Background: Oral lichen planus (OLP) is a common mucocutaneous disease with malignant transformation potential. Several etiologies such as humoral, autoimmunity, and viral infections might play a role, but still there is no definite etiology for this disease. The aim of this study was to investigate the presence of Epstein–Barr virus (EBV) genome in Iranian patients with OLP as compared to people with normal mucosa. Materials and Methods: The study was carried out on a case group including 38 tissue specimens of patients with histopathological confirmation of OLP and a control group including 38 samples of healthy mucosa. All samples were examined by nested polymerase chain reaction (PCR) method to determine the DNA of EBV. Results: Twenty-two (57.9%) female samples and 16 (42.1%) male samples with OLP were randomly selected as the case group, and 20 (52.6%) female samples and 18 (47.4%) male samples with healthy mucosa as the control group. There was a statistically significant difference in the percentage of EBV positivity between the case (15.8%) and the control groups (P < 0.05); in the case group, three female samples (13.6%) and three male samples (18.8%) were infected with EBV; the difference between the genders was not statistically significant (P = 0.50). Conclusion: Results emphasized that EBV genome was significantly higher among Iranian patients with OLP so antiviral therapy might be helpful. PMID:29692821

There was a statistically significant difference in the percentage of EBV positivity between the case (15.8%) and the control groups ( P < 0.05); in the case group, three female samples (13.6%) and three male samples (18.8%) were infected with EBV; the difference between the genders was not statistically significant ( P = 0.50). Results emphasized that EBV genome was significantly higher among Iranian patients with OLP so antiviral therapy might be helpful.

Vitamin D (Vit D) deficiency is a common disorder in diabetic patients and may be a risk factor for ischemic heart disease and exacerbation of diabetic nephropathy(DN). The aim of this study was to evaluate the effect of Vit D3 therapy on protein uriain type 2 diabetic patients with deficient or insufficient serum Vit D. In a double blind clinical trial, 60 type 2 diabetic patients with proteinuria greater than 150 mg/day who had Vit D deficiency or insufficiency were randomly enrolled in two equal groups. Pearl of Vit D as 50 000 IU/week and placebo (1 tablet per week) were prescribed in patients of case and control groups respectively for 8 weeks. At the beginning and 2 months later, 24 hours urine protein was checked in all patients. There is no difference between serums Vit D level in case and control group at the beginning of the study, however at the end of the study serum Vit D level was significantly higher in the case group. There is no difference in proteinuria between case and control group at the beginning and the end of the study, while a significant difference between the changes of proteinuria before and after the study was seen in two groups ( P = 0.028). Vit D deficiency may exacerbate protein uric and DN, hence correction of Vit D deficiency may decrease proteinuria in diabetic patients with nephropathy.

In the daily practice of forensic pathology, sudden cardiac death (SCD) is a diagnostic challenge. Our aim was to determine the usefulness of blood biomarkers [creatine kinase CK-MB, myoglobin, troponins I and T (cTn-I and T), and lactate dehydrogenase] measured by immunoassay technique, in the postmortem diagnosis of SCD. Two groups were compared, 20 corpses with SCD and 8 controls. Statistical significance was determined by variance analysis procedures, with a post hoc Tukey multiple range test for comparison of means (p < 0.05). SCD cases showed significantly higher levels (p < 0.05) of cTn-T and cTn-I compared to the control group. Although only cases within the first 8 h of postmortem interval were included, and the control group consisted mainly of violent death cases, our results suggest that blood troponin levels may be useful to support a diagnosis of SCD. © 2017 American Academy of Forensic Sciences.

To examine the effect overactive bladder (OAB) and other lower urinary tract symptoms (LUTS) on health-related quality of life (HRQoL) in a population sample, as OAB often occurs in conjunction with many other LUTS. A nested case-control analysis was performed on men and women with (cases) and without (controls) OAB, from the EPIC study. OAB was assessed using 2002 International Continence Society definitions. Based on their responses to questions about LUTS, cases were classified into five groups; continent OAB, OAB with incontinence, OAB + postmicturition, OAB + voiding, and OAB + postmicturition + voiding. Both cases and controls were asked questions about symptom bother (OAB-q), generic QoL (EQ-5D), work productivity (Work Productivity and Activity Impairment, WPAI), depressive symptoms (Center for Epidemiologic Studies Depression Scale), sexual satisfaction, and erectile dysfunction (men only) using the Massachusetts Male Aging Study. Cases answered additional condition-specific questions HRQoL (OAB-q short form), Patient Perception of Bladder Condition and work productivity related to a specific health problem (WPAI-SHP). General linear models were used to evaluate group differences. Of the EPIC participants, 1434 identified OAB cases were matched by age, gender and country, with 1434 participants designated as controls. Cases and controls were primarily Caucasian (96.2% and 96.7%, respectively), and most (65%) were female; the mean age was 53.8 and 53.7 years, respectively. Comorbid conditions differed significantly by case/control status, with cases reporting significantly greater rates of chronic constipation, asthma, diabetes, high blood pressure, bladder or prostate cancer, neurological conditions and depression. There were significant differences between the cases and controls in all reported LUTS. The OAB + postmicturition + voiding group reported significantly greater symptom bother, worse HRQoL, higher rates of depression and decreased enjoyment of sexual activity, than the other subgroups. OAB has a substantial, multidimensional impact on patients; OAB with additional LUTS has a greater impact. The diagnosis and treatment of OAB should be considered in conjunction with other LUTS, to maximize treatment options and optimize patient outcomes.

Background Most patients with infective endocarditis (IE) manifest fever. Comparison of endocarditis patients with and without fever, and whether the lack of fever in IE is a marker for poorer outcomes, such as demonstrated in other severe infectious diseases, have not been defined. Methods and Results Cases from the Mayo Clinic, Rochester, Minnesota, Division of Infectious Diseases IE registry, a single-center database that contains all cases of IE treated at our center. Diagnosis date between 1970 and 2006, which met the modified Duke criteria for definite endocarditis, without fever was included. There were 240 euthermic endocarditis cases included in this analysis, with 282 febrile controls selected by frequency matching on gender and decade of diagnosis. Euthermic patients had a median age of 63.6 years (±16.1) as compared to 59.0 years (±16.4) in the febrile control group (p=0.001). Median (IQR) symptom duration prior to diagnosis was 4.0 (1.0, 12.0) weeks in the euthermic group compared to 3.0 (1.0, 8.0) weeks in the febrile controls (p= 0.006). From unadjusted analyses, survival rates were 87% in euthermic cases versus 83% in febrile controls across 28-day follow-up (p=0.164), and 72% in euthermic group cases versus 69% in febrile controls across 1-year follow-up (p=0.345). Also unadjusted, the 1-year cumulative incidence rate of valve surgery was higher in euthermic cases versus febrile controls (50% vs. 39%, p= 0.004). Conclusions Patients with euthermic endocarditis are older, and lack of fever was associated with longer symptom duration and delayed diagnosis prior to IE diagnosis. Despite a higher unadjusted rate of valve surgery in euthermic patients, the result was not significant when adjusting for baseline confounders. Differences in survival rates at both 28-days and 365-days were not statistically significant between the two groups. PMID:24244630

Objective: Fungal urinary tract infections due to Candida have increased significantly in recent years. Our research objective was to study Candida species in urine samples of patients with urinary tract infections (UTIs) associated with obstructive uropathy and to investigate the virulence factors of the isolated Candida. Methods: Patients were divided into two groups: Group I (cases): 50 patients with UTIs and obstructive uropathy. Group II (control): 50 patients with UTIs but with no functional or anatomical obstruction of their urinary tract. Clinical histories and physical examinations, together with laboratory investigations of urine samples were carried out in all patients in this study. Mid stream urine samples were examined microscopically and by fungal cell culture. The isolated Candida species were identified by analytical profile index (API). Candida Virulence factors were determined for the isolated Candida. The susceptibility to fluconazole was evaluated. Results: This study revealed an overall isolation rate of 27% of Candida species among all patient groups. The rate was 36% in cases, and 18% in controls, a difference found to be statistically significant (P<0.05). By API, C.albicans was detected in 44% of Candida species in cases, and in 33% in controls. While C.glabrata was detected in 28% of Candida species in cases, and in 22% in controls. C.tropicalis was detected in 17% of Candida species in cases, and in 22% in controls. Both C.krusei and C.kyfr were detected in 5.5% of Candida species in cases, and in 11% in controls. In terms of virulence factors the study showed that 11 out of 27 (40.5%) of Candida isolates were biofilm positive by tube adherence. Phospholipase activity was demonstrated in 12 out of 27 (44.5%) of Candida isolates. Secretory aspartic proteinase activity was demonstrated in 13 out of 27 (48%) of the Candida isolates. Conclusion: Candida is an important cause of UTIs and obstructive uropathy is a major predisposing factor. PMID:27022363
Implementing Group Medical Visits for Older Adults at Group Health Cooperative

In a pair of randomized controlled trials in Kaiser Colorado in the 1990s, Group Visits for older adults (monthly non disease-specific group medical appointments for a cohort of patients led by primary care teams) were proven to reduce costs, decrease hospitalizations, and improve patient and provider satisfaction. As part of a translational effort, this Group Visit intervention was replicated in a delivery system in Seattle, WA, and the log of total health care costs measured in the first year of the intervention. Utilization and patient and physician satisfaction were secondary outcomes. For the cost and utilization analysis, a retrospective case-control design compared 221 case patients 65 years of age and older with high outpatient utilization in the previous 18 months with 1,015 control patient selected randomly from clinics not participating in the intervention. Controls were matched to cases on the number of primary care visits in the prior 18 months. Total costs were not statistically different for intervention patients compared to controls ($8,845 vs. $10,288, p=0.11), nor were there statistically significant differences in utilization, including hospital admissions and outpatient visits. However, patient and provider satisfaction was high. This translational effort did not demonstrate the cost savings of the original efficacy trials. Possible explanations for these divergent results may have to do with differences in those who participated and differences between the two delivery systems. PMID:20002506

Intrauterine hematomas are a common pregnancy complication. The literature lacks studies about outcomes based on hematoma localization. Thus, we aimed to compare pregnancies complicated by an intraplacental hematoma to cases with a retroplacental hematoma and to a control group. In a retrospective case-control study, 32 women with an intraplacental hematoma, 199 women with a retroplacental hematoma, and a control group consisting of 113 age-matched women with no signs of placental abnormalities were included. Main outcome measures were pregnancy complications. Second-trimester miscarriage was most common in the intraplacental hematoma group (9.4%), followed by women with a retroplacental hematoma (4.2%), and controls (0%; p = 0.007). The intraplacental hematoma group revealed the highest rates for placental insufficiency, intrauterine growth retardation, premature preterm rupture of membranes, preterm labor, preterm delivery <37 weeks, and early preterm delivery <34 weeks (p < 0.05), followed by the retroplacental hematoma group. When tested in multivariate models, intraplacental hematomas were independent predictors for placental insufficiency (ß = 4.19, p < 0.001) and intrauterine growth restriction (ß = 1.44, p = 0.035). Intrauterine fetal deaths occurred only in women with a retroplacental hematoma (p = 0.042). Intra- and retroplacental hematomas have different risk profiles for the affected pregnancy and act as independent risk factors.

The aim of this study was to investigate the prevalence and intensity of masticatory muscle and temporomandibular joint (TMJ) pain in Croatian war veterans with posttraumatic stress disorder (PTSD). The examined group consisted of 100 Croatian war veterans, in whom PTSD had previously been diagnosed. Patients were compared with 92 subjects who had not taken part in the war and in whom PTSD was excluded by psychiatric examination. The clinical examination consisted of palpation of the masticatory muscles, the prominent neck musculature, and TMJ. The examination technique used and the definition of items were previously tested for reliability and validity. 93% of the subjects with PTSD had masticatory muscle tenderness compared to 45.65% of the subjects in the control group (chi2 = 51.46, p < 0.0001). The most frequent painful location in the subjects with PTSD was the left lateral pterygoid site in 88%, and in subjects of the control group the right lateral pterygoid site in 28.26% of cases. The most painful location in the PTSD group was the left lateral pterygoid site in 72%, and in the control group the left posterior digastric in 4.35% of cases. 58% of the subjects with PTSD had TMJ tenderness compared to 3.26% of subjects in the control group (chi2 = 66.23, p < 0.0001). The most frequent painful location of TMJ in both groups was the left posterior capsule; in the PTSD group 38% and in subjects in the control group 2.17% of cases. The most painful location was the left posterior capsule in 28% of subjects with PTSD, while not one subject in the control group reported severe painful sensitivity. The very high frequency and intensity of pain in subjects with PTSD confirms the effect of stress on muscle and joint sensitivity, i.e. perception of pain.

We discuss the analytic and practical considerations in a large case-control study that had two control groups; the first control group consisting of partners of patients and the second obtained by random digit dialling (RDD). As an example of the evaluation of a general lifestyle factor, we present body mass index (BMI). Both control groups had lower BMIs than the patients. The distribution in the partner controls was closer to that of the patients, likely due to similar lifestyles. A statistical approach was used to pool the results of both analyses, wherein partners were analyzed with a matched analysis, while RDDs were analyzed without matching. Even with a matched analysis, the odds ratio with partner controls remained closer to unity than with RDD controls, which is probably due to unmeasured confounders in the comparison with the random controls as well as intermediary factors. However, when studying injuries as a risk factor, the odds ratio remained higher with partner control subjects than with RRD control subjects, even after taking the matching into account. Finally we used factor V Leiden as an example of a genetic risk factor. The frequencies of factor V Leiden were identical in both control groups, indicating that for the analyses of this genetic risk factor the two control groups could be combined in a single unmatched analysis. In conclusion, the effect measures with the two control groups were in the same direction, and of the same order of magnitude. Moreover, it was not always the same control group that produced the higher or lower estimates, and a matched analysis did not remedy the differences. Our experience with the intricacies of dealing with two control groups may be useful to others when thinking about an optimal research design or the best statistical approach.

Small variations in trace element levels may cause important physiological changes in the human body. This study aims to evaluate five important trace elements in radiation workers. In this study, 44 radiation workers and an equal number of non-radiation workers were selected as the case and control group, respectively. The concentrations of iron, magnesium, zinc, copper, and selenium in the serum of the participants were measured using an Atomic Absorption Spectrometry (AAS). The mean concentrations of iron, magnesium, zinc, copper, and selenium for the case group were 107.3 µg/dl, 2.3 mg/dl, 80.9 µg/dl, 112.6 µg/dl and 216.7 ng/ml, respectively. The results for the control group were 121.9 µg/dl, 2.3 mg/dl, 82.3 µg/dl, 112.8 µg/dl and 225.2 ng/ml, respectively. The mean concentration of iron in the case group was significantly lower than the control group (p-value = 0.012), while the concentrations of other elements in both of the groups were not significantly different. In the case group, except magnesium (p-value = 0.021), no significant relationship was found between age and the elemental concentrations. According to Spearman's test, there was a meaningful statistical correlation between the sex and concentration of iron, Mg, Zn, and Se. Also, the correlation between the concentration of magnesium and the weights of radiation workers was significant (p-value =0.044). © 2018 Old City Publishing, Inc.

Unintentional poisoning in young children is an important public health issue. Age pattern studies have demonstrated that children aged 1-3 years have the highest levels of poisoning risk among children aged 0-4 years, yet little research has been conducted regarding risk factors specific to this three-year age group and the methodologies employed varied greatly. The purpose of the current study is to investigate a broad range of potential risk factors for unintentional poisoning in children aged 1-3 years using appropriate methodologies. Four groups of children, one case group (children who had experienced a poisoning event) and three control groups (children who had been 'injured', 'sick' or who were 'healthy'), and their mothers (mother-child dyads) were enrolled into a case-control study. All mother-child dyads participated in a 1.5-hour child developmental screening and observation, with mothers responding to a series of questionnaires at home. Data were analysed as three case-control pairs with multivariate analyses used to control for age and sex differences between child cases and controls. Five risk factors were included in the final multivariate models for one or more case-control pairs. All three models found that children whose mothers used more positive control in their interactions during a structured task had higher odds of poisoning. Two models showed that maternal psychiatric distress increased poisoning risk (poisoning-injury and poisoning-healthy). Individual models identified the following variables as risk factors: less proximal maternal supervision during risk taking activities (poisoning-injury), medicinal substances stored in more accessible locations in bathrooms (poisoning-sick) and lower total parenting stress (poisoning-healthy). The findings of this study indicate that the nature of the caregiver-child relationship and caregiver attributes play an important role in influencing poisoning risk. Further research is warranted to explore the link between caregiver-child relationships and unintentional poisoning risk. Caregiver education should focus on the benefits of close interaction with their child as a prevention measure.

Because glioma etiology is largely unknown, the inverse association of glioma risk with atopic conditions is promising and deserves close scrutiny. We examined the association between a history of allergies, asthma, and eczema and glioma risk using sibling, friend, and clinic-based controls. This analysis included 388 incident glioma cases and 80 sibling, 191 friend, and 177 clinic-based controls. Each subject’s medical history was assessed via a web-based or telephone survey. Odds ratios (ORs) and their 95% confidence intervals for the associations with allergies, asthma, eczema, and the overall number of these conditions were calculated from conditional (for sibling and friend controls) and unconditional (for clinic-based controls) logistic models. Allergies were consistently inversely associated with the glioma: ORs were 0.53 (95% CI, 0.15–1.84), 0.54 (95% CI, 0.28–1.07), and 0.34 (95% CI, 0.23–0.50) with sibling, friend, and clinic-based controls, respectively. Asthma showed an inverse association only in the comparison with sibling controls (OR=0.43; 95% CI, 0.19–1.00). Eczema showed an inverse association only in the comparison with friend controls (OR=0.42; 95% CI, 0.15–1.18). The overall number of these conditions (ordinal score 0, 1, 2, 3) was inversely associated with glioma: The risk decreased 31–45% with each addition of an atopic condition. These estimates were the most stable when different control groups were considered. Comparing the prevalence of these conditions in the three control groups with published data, we note that clinic-based controls generally better approximate the prevalence data for population-based groups. These controls appear to present a reasonable choice for clinic-centered case-control studies. PMID:19336556

The aim of this study was to evaluate the effect of an Assertive Community Treatment (ACT) program on psychiatric symptoms, global functioning, life satisfaction, and recovery-promoting relationships among individuals with mental illness. Participants were patients at the Suwon Mental Health Center. Thirty-two patients were part of the ACT program and 32 patients matched for age, sex, and mental illness were in a standard case-management program and served as a control group. Follow-up with patients occurred every 3 months during the 15 months after a baseline interview. Participants completed the Brief Psychiatric Rating Scale (BPRS), Global Assessment of Functioning (GAF) Scale, Life Satisfaction Scale, and Recovery-Promoting Relationship Scale (RPRS). No significant differences were noted in the sociodemographic characteristics of the ACT and the case-management group. According to the BPRS, the ACT group showed a significant reduction in symptom severity, but the ACT program was not significantly more effective at reducing psychiatric symptoms from baseline to the 15-month follow-up compared to the case-management approach. The ACT group showed more significant improvement than the control group in terms of the GAF Scale. Both groups showed no significant differences in the change of life satisfaction and in the change of recovery-promoting relationships. We observed a significant increase in recovery-promoting relationships in the control group, but the degree of change of recovery-promoting relationships through time flow between groups was not significantly different. In this study, we observed that ACT was significantly better at improving the GAF than case management and that participation in ACT was associated with a significant decrease in BPRS scores. However, ACT did not demonstrate an absolute superiority over the standard case-management approach in terms of the BPRS and the measures of life satisfaction and recovery-promoting relationships. ACT may have some advantages over a standard case management approach.

The aim of this study was to investigate perinatal outcome and the rate of cesarean section (CS) following intrapartum amnioinfusion in women with meconium-stained amniotic fluid (MSAF). A total of 100 women at term in labor with meconium were randomized to infuse transcervical intrapartum amnioinfusion with saline (50) and routine obstetrical care (50). Perinatal outcome and obstetric outcome were recorded and analyzed in both groups by means of Chi-square test. The CS rate due to fetal distress was 40.0 % in the control group and 20.0 % in the study group. The difference was statistically significant (P < 0.01). Respiratory distress of the neonate was significantly less common in the study group than in the control group (4.0 % vs. 12 %; P = 0.0349). Amnioinfusion in cases of meconium-stained liquor significantly improved neonatal outcome and CS rate without increasing any maternal and fetal complications.

To observe the clinical efficacy of acupuncture and moxibustion periodic therapy on folli-cular maldevelopment differentiated as spleen and kidney yang deficiency. Sixty patients of follicular maldevelopment differentiated as spleen and kidney yang deficiency were randomized as an observation group and a control group, 30 cases in each one. The conventional acupuncture-moxibustion therapy was used in the control group and the acupuncture-moxibustion periodic therapy was applied to the observation group. In the control group, the acupoints were selected in terms of spleen and kidney yang deficiency, such as Guanyuan (CV 4), Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3), Xuehai (SP 10) and Zigong (EX-CA 1). In the observation group, the acupoints were selected in terms of the physiological characteristics of follicular phase, ovulatory phase, luteal phase and menstrual phase. The main acupoints were Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3) and Xuehai (SP 10). The acupoints for benefiting kidney yin were added in the follicular phase, such as Guanyuan (CV 4) and Dahe (KI 12), etc. The acupoints for regulating qi and activating blood circulation were added in the ovulatory phase, such as Hegu (LI 4) and Taichong (LR 3), etc. The moxibustion was added for tonifying kidney yang in the luteal phase, such as Qihai (CV 6) and Guanyuan (CV 4). The treatment was discontinued during the menstrual phase in the two groups. In the rest phases, acupuncture and moxibustion were given once every two days, 30 min each time. The overall efficacy, basal body temperature (BBT), follicular development, the average endometrial thickness and morphology as well as TCM syndrome score of spleen and kidney yang deficiency were observed in the patients after 3-month menstrual periods. The adverse reactions were recorded in the two groups. In the observation group, one case gave up the treatment due to the personal reason and another one stopped the treatment due to suffering from another kind of disease. 28 cases were included totally. In the control group, 3 cases were dropped out since attempting to receive in vitro fertilization-embryo transfer (IVF-ET) and 27 cases were finally included. The total effective rate was 92.9% (26/28) in the observation group, better than 85.2% (23/27) in the control group ( P <0.05). Except the endometrial morphology in the control group, after treatment, BBT, follicular development, the average endometrial thickness and morphology as well as TCM syndrome score were all improved apparently after treatment in the two groups (all P <0.05). The improvements in follicular development, endometrial morphology and TCM syndrome score in the observation group were more obvious as compared with those in the control group (all P <0.05). The incidence of the adverse reaction was 7.1% (2/28) in the observation group and was 3.7% (1/27) in the control group, indicating mild adverse reaction that could be relieved naturally. The treatment with acupuncture and moxibustion achieves the significant efficacy on follicular maldevelopment differentiated as spleen and kidney yang deficiency. Compared with conventional acupuncture-moxibustion therapy, the periodic therapy of acupuncture and moxibustion achieves the much better clinical efficacy.

The purpose of this study was to examine the effects of a cultural competence improvement program for maternity nurses. A quasi-experimental study using a non-equivalent control group pre and posttest design was used. Participants were 67 maternity nurses caring for multicultural pregnant women in G city. The cultural competence improvement program was developed based on the 3-D Puzzle Model and was provided using case-based small group learning methods for the experimental group (n=31). The control group (n=36) did not receive any intervention. Data were collected using self-report structured questionnaires at two time points: prior to the intervention and after the intervention and were analyzed with descriptive statistics, χ²-test, and t-test. Compared to the control group, the experimental group reported significant positive changes for cultural knowledge (t=6.39, p<.001), cultural awareness (t=3.50, p<.001), and cultural acceptance (t=4.08, p<.001). However, change in cultural nursing behaviors (t=0.92, p=.067) was not significantly different between the two groups. Findings from this study indicate that a cultural competence improvement program with case-based small group learning is a useful intervention strategy to promote multicultural maternity care. Further, strategies to improve cultural nursing behavior should be developed to promote culturally congruent nursing care.

We aimed to compare effectiveness of Wenxin Keli (WK) and sotalol in assisting sinus rhythm (SR) restoration from paroxysmal atrial fibrillation (PAF) caused by hyperthyroidism, as well as in maintaining SR. We randomly prescribed WK (18 g tid) or sotalol (80 mg bid) to 91 or 89 patients. Since it was not ethical not to give patients antiarrhythmia drugs, no control group was set. Antithyroid drugs were given to 90 patients (45 in WK group, 45 in sotalol group); 131I was given to 90 patients (46 in WK group, 44 in sotalol group). Three months later, SR was obtained in 83/91 or 80/89 cases from WK or sotalol groups (P = 0.762). By another analysis, SR was obtained in 86/90 or 77/90 cases from 131I or ATD groups (P = 0.022). Then, we randomly assigned the successfully SR-reverted patients into three groups: WK, sotalol, and control (no antiarrhythmia drug was given) groups. After twelve-month follow-up, PAF recurrence happened in 1/54, 2/54, and 9/55 cases, respectively. Log-Rank test showed significant higher PAF recurrent rate in control patients than either treatment (P = 0.06). We demonstrated the same efficacies of WK and sotalol to assist SR reversion from hyperthyroidism-caused PAF. We also showed that either drug could maintain SR in such patients. PMID:26074982

Drug abuse is a major public health problem. Some believe that when dissociation fails to defend against emotional, physical, or sexual trauma, the person will find relief from unpleasant thoughts and emotions in opium use. On the other hand, personality disorders are considered as important predictors of treatment outcomes in drug abusers. Due to lack of adequate research in this regard, we evaluated dissociative disorders and personality traits of opium addicts on methadone treatment. This cross-sectional analytic study included 111 non-psychotic subjects on methadone treatment (case group) and 69 non-addicts (control group). After recording demographic characteristics, Dissociative Experiences Scale (DES) and Millon Multiaxial Inventory III were applied to assess dissociative symptoms and clinical personality patterns of all participants. Dissociative symptoms were significantly more common in the case group than in the control group (P = 0.044). While hysterionic personality disorder was more frequent in the control group (P = 0.008), sadistic, antisocial, and schizotypal personality disorders were significantly more common in the case group (P = 0.008, 0.002, and 0.023, respectively). We found relations between history of drug dependence, dissociative symptoms, and personality disorders. Therefore, the mentioned disorders need to be kept in mind while planning addiction treatment modalities and identifying high risk groups.

In clinical research of rare diseases, where small patient numbers and disease heterogeneity limit study design options, registries are a valuable resource for demographic and outcome information. However, in contrast to prospective, randomized clinical trials, the observational design of registries is prone to introduce selection bias and negatively impact the validity of data analyses. The objective of the study was to demonstrate the utility of case-control matching and the risk-set method in order to control bias in data from a rare disease registry. Data from the International Collaborative Gaucher Group (ICGG) Gaucher Registry were used as an example. A case-control matching analysis using the risk-set method was conducted to identify two groups of patients with type 1 Gaucher disease in the ICGG Gaucher Registry: patients with avascular osteonecrosis (AVN) and those without AVN. The frequency distributions of gender, decade of birth, treatment status, and splenectomy status were presented for cases and controls before and after matching. Odds ratios (and 95% confidence intervals) were calculated for each variable before and after matching. The application of case-control matching methodology results in cohorts of cases (i.e., patients with AVN) and controls (i.e., patients without AVN) who have comparable distributions for four common parameters used in subject selection: gender, year of birth (age), treatment status, and splenectomy status. Matching resulted in odds ratios of approximately 1.00, indicating no bias. We demonstrated bias in case-control selection in subjects from a prototype rare disease registry and used case-control matching to minimize this bias. Therefore, this approach appears useful to study cohorts of heterogeneous patients in rare disease registries.

Ulcerative colitis (UC) is a chronic relapsing inflammatory disease with significant clinical diversity. However, the aetiology, pathogenesis and optimal treatment of UC remain unclear. The purpose of this case-control study was to investigate the association between previously diagnosed hyperthyroidism and UC using a large population-based data set in Taiwan. The data for this population-based case-control study were retrieved from the Taiwan Longitudinal Health Insurance Database 2005. We included 2709 patients with UC as cases and 8127 sex- and age-matched patients without UC as controls. A conditional logistic regression analysis was conducted to compute the odds ratio (OR) and corresponding 95% confidence interval (CI) for the association between UC and prior hyperthyroidism. We found that, in total, 327 of the 10 836 sampled patients (3.02%) had previously been diagnosed with hyperthyroidism. There was a higher proportion of prior hyperthyroidism among cases than controls (4.10% vs 2.66%, P<.001). A conditional logistic regression showed that the OR of prior hyperthyroidism was 1.57 (95% CI=1.24-1.98) compared to controls. Similarly, after adjusting for monthly income, geographic location and urbanization level, cases were still more likely to have previously been diagnosed with hyperthyroidism than controls (OR=1.61, 95% CI=1.27-2.05). Furthermore, we analysed the ORs of prior hyperthyroidism between cases and controls according to age group. We found that of the youngest group of sampled patients (18-39 years), cases had the greatest adjusted OR for having previously been diagnosed with hyperthyroidism than controls (OR=1.98, 95% CI=1.04-3.79). This study demonstrated an association between UC and hyperthyroidism. © 2017 John Wiley & Sons Ltd.

Childhood trauma is emerging as a risk factor for schizophrenia, but its mechanism with respect to etiology is unknown. One possible pathway is through leucocyte telomere length (LTL) shortening, a measure of cellular aging associated with trauma. This study examined early trauma and LTL shortening in schizophrenia and considered sex effects. The early trauma inventory (ETI) was administered to 48 adults with DSM-5 schizophrenia and 18 comparison participants. LTL was measured using qPCR. Cases had significantly more global trauma (F=4.10, p<0.01) and traumatic events (F=11.23, p<0.001), but case and control groups had similar LTL (1.91±0.74 and 1.83±0.62: p=0.68). The association of early trauma and LTL differed by sex in cases and controls (Fisher's R: Z<0.05). Significant negative associations were shown in male cases and, conversely, in female controls. For example, physical punishment was associated LTL shortening in males' cases (r=-0.429, p<01). Only female controls showed significant telomere shortening in association with early trauma. This data confirms the substantial excess of early trauma among schizophrenia cases. There were significant sex-differences in the relationship of the trauma to LTL, with only male cases showing the expected shortening. There were converse sex effects in the control group. Mean LTL was notably similar in cases and controls, despite the trauma-related shortening in male cases, cigarette smoking, older age and chronic illness of the cases. Factors may lengthen LTL in some schizophrenia cases. The converse sex differences in the cases are consistent with findings defective sexual differentiation in schizophrenia, consistent with other findings in the field. Copyright © 2018 Elsevier B.V.

The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, and presentation of the results of case-control vaccine effectiveness studies. Vaccination status is the primary exposure of interest, but can be challenging to assess accurately and with minimal bias. Investigators should understand factors associated with vaccination as well as the availability of documented vaccination status in the study context; case-control studies may not be a valid method for evaluating vaccine effectiveness in settings where many children lack a documented immunization history. To avoid bias, it is essential to use the same methods and effort gathering vaccination data from cases and controls. Variables that may confound the association between illness and vaccination are also important to capture as completely as possible, and where relevant, adjust for in the analysis according to the analytic plan. In presenting results from case-control vaccine effectiveness studies, investigators should describe enrollment among eligible cases and controls as well as the proportion with no documented vaccine history. Emphasis should be placed on confidence intervals, rather than point estimates, of vaccine effectiveness. Case-control studies are a useful approach for evaluating vaccine effectiveness; however careful attention must be paid to the collection, analysis and presentation of the data in order to best inform evidence-based vaccine policies.

Purpose: To measure, quantify and compare Ocular Aberrations due to nuclear cataracts. Setting: Department of ophthalmology and school for ophthalmic technicians, college of medicine and health sciences, Sultan Qaboos University, Muscat, Oman. Design: Retrospective case controlled study. Methods: 113 eyes of 77 patients with nuclear cataract (NC) were recruited from outpatient clinic of a major tertiary referral center for Ophthalmology. Patients having NC with no co-existing ocular pathologies were selected. All patients were subjected to wavefront aberrometry (make) using Hartmann-Shack (HS) aberrometer. Consents were taken from all patients. Higher order Aberrations (HOA) were calculated with Zernike polynomials up to the fourth order. For comparison 28 eyes of 15 subjects with no lenticular opacities (control group) were recruited and evaluated in an identical manner. No pupillary mydriasis was done in both groups. Results: Total aberrations were almost six times higher in NC group compared to control (normal) subjects. The HOA were 21 times higher in NC group, and coma was significantly higher in NC eyes compared to normal (control) group. The pupillary diameter was significantly larger in control group (5.48mm ± 1.0024, p<.001) compared to NC (3.05mm ± 1.9145) subjects (probably due to younger control age group). Amongst Zernike coefficients up to fourth order, two polynomials, defocus (Z20) and spherical aberration (Z42) were found to be significantly greater amongst NC group, compared to normal control group. Conclusion: Nuclear cataracts predominantly produce increased defocus and spherical aberrations. This could explain visual symptoms like image deterioration in spite of normal Visual acuity.

The aim of the study was to investigate pH and viscosity (h) of gall bladder contents during cholelithiasis and establishment of their correlation with bacterial and HBV infections. Seventy-eight patients undergone the planned cholecystectomy were investigated. 5 healthy persons (control group) were also involved into the study. In all cases the markers of HBV (Anti-HB core IgG, Anti-HB core IgM, HBsAg) in blood were detected, also bacteriological analysis of gall bladder tissue was performed. In 78 cases (I group) pH of gall bladder contents was measured, in 29 cases (II group), also viscosity of gall was studied. In the control group pH and viscosity were detected. Statistical analysis was performed using ANOVA method. Bacteriological study revealed presence of bacterial infection in gall bladder tissue in 34 cases (43,6%), in 30 patients Anti-HB core antibodies were found in the blood, in 13 cases (16,7%) coincidence of bacterial and HBV infection was documented. Mean indexes of pH and viscosity appeared to be significantly higher in the operated group (pH--7,30, h 2,1 mm(2)/sec), then in the control group (pH--6,74, h--1,34 mm(2)/sec); this indexes were highest in the infected patients. Thus, according to results of the study, changes of pH and viscosity of gall bladder contents could be considered as the useful indexes of initial stage of cholelithiasis and their values depend on the presence of bacterial or HBV infection of gall bladder.

Previous studies have reported the normative values of pelvic sagittal parameters, but no study has analyzed the sagittal spino-pelvic alignment in degenerative lumbar scoliosis (DLS) and its role in the pathogenesis. Retrospective analysis was applied to 104 patients with DLS, together with 100 cases of asymptomatic young adults as a control group and another control group consisting of 145 cases with cervical spondylosis. The coronal and sagittal parameters were measured on the anteroposterior and lateral radiograph of the whole spine in the DLS group as well as in the two control groups. Statistical analysis showed that the DLS group had a higher pelvic incidence (PI) value (50.5° ± 10.2°), than the normal control group (with PI 47.2° ± 8.8°) and the cervical spondylosis group (46.9° ± 9.1°). In DLS group, there were 38 cases (36.5%) complicated with degenerative lumbar spondylolisthesis, who had higher PI values than patients without it. Besides, the lumbar lordosis (LL) and sacral slope (SS) of DLS group were lower; the scoliosis Cobb's angle was correlated with pelvic tilt (PT); thoracic kyphosis was correlated with LL, SS, and PT; and LL was correlated with other sagittal parameters. Patients with DLS may have a higher PI, which may impact the pathogenesis of DLS. A high PI value is probably associated with the high prevalence of degenerative lumbar spondylolisthesis among DLS patients. In DLS patients, the lumbar spine maintains the ability of regulating the sagittal balance, and the regulation depends more on thoracic curve.

Along with the proliferation of Open Access (OA) publishing, the interest for comparing the scientific quality of studies published in OA journals versus subscription journals has also increased. With our study we aimed to compare the methodological quality and the quality of reporting of primary epidemiological studies and systematic reviews and meta-analyses published in OA and non-OA journals. In order to identify the studies to appraise, we listed all OA and non-OA journals which published in 2013 at least one primary epidemiologic study (case-control or cohort study design), and at least one systematic review or meta-analysis in the field of oncology. For the appraisal, we picked up the first studies published in 2013 with case-control or cohort study design from OA journals (Group A; n = 12), and in the same time period from non-OA journals (Group B; n = 26); the first systematic reviews and meta-analyses published in 2013 from OA journals (Group C; n = 15), and in the same time period from non-OA journals (Group D; n = 32). We evaluated the methodological quality of studies by assessing the compliance of case-control and cohort studies to Newcastle and Ottawa Scale (NOS) scale, and the compliance of systematic reviews and meta-analyses to Assessment of Multiple Systematic Reviews (AMSTAR) scale. The quality of reporting was assessed considering the adherence of case-control and cohort studies to STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) checklist, and the adherence of systematic reviews and meta-analyses to Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) checklist. Among case-control and cohort studies published in OA and non-OA journals, we did not observe significant differences in the median value of NOS score (Group A: 7 (IQR 7-8) versus Group B: 8 (7-9); p = 0.5) and in the adherence to STROBE checklist (Group A, 75% versus Group B, 80%; p = 0.1). The results did not change after adjustment for impact factor. The compliance with AMSTAR and adherence to PRISMA checklist were comparable between systematic reviews and meta-analyses published in OA and non-OA journals (Group C, 46.0% versus Group D, 55.0%; p = 0.06), (Group C, 72.0% versus Group D, 76.0%; p = 0.1), respectively). The epidemiological studies published in OA journals in the field of oncology approach the same methodological quality and quality of reporting as studies published in non-OA journals.

Symptomatic vasospasm (SVS) is still a major cause of poor outcome in cases undergoing early surgical intervention for ruptured intracranial aneurysm. Among the numbers of therapeutic trials to prevent and ameliorate neurological deterioration due to SVS, removal or quenching of oxy-hemoglobin (OxyHb) from subarachnoid colts and administration of Mg(2+) (Mg) have especially been expected to be effective. In this report the authors investigated the effect of continuous cisternal irrigation (CCI) with mock CSF containing ascorbic acid (ASA) and Mg, performed after early surgery for ruptured aneurysm. Sixty-three cases which had received CCI were retrospectively compared with 40 control cases as to the incidence of SVS and outcome. Incidence of SVS was significantly less frequent (P < 0.05) in the CCI group (11%) than in the control group (25%). Severe and definitive SVS requiring additional specific treatment occurred only in 3.2% of the CCI group, while 22.5% in the control (P < 0.01). Overall outcome at discharge was significantly better in the CCI group than in the control (P < 0.01). Postoperative CCI with ASA and Mg was definitively effective in preventing SVS and in lessening severity of SVS if it occurs.
Enhancing situational interest in pediatrics.

Individual interest, something that persists regardless of the situation, and situational interest, finding personal value in an educational context, have not been studied in medical student education. To determine if individualized case discussions enhance interest in pediatric medicine. During the 2008/2009 academic year, 88 clerkship students participated in clinical case discussions. At orientation, students completed an Interest in Pediatrics (IIP) questionnaire, responding 1 = strongly disagree to 5 = strongly agree. Intervention and control groups were randomly assigned. The intervention group personalized cases to students' medical specialty interests. The control group discussed the case presentation. Groups met twice during the 8-week clerkships, completing a post-IIP at the end of the clerkship. Intervention group interest increased from pre-IIP, mean = 3.64, to post-IIP, mean = 4.22 (z = -2.994, p < 0.05, r = -0.44). On post-IIP, application of pediatric medicine increased for both groups; the intervention group was most significant from pre-IIP, mean = 1.09, to post-IIP, mean = 4.33 (z = -6.038, p < 0.05, r = -0.88). Enhanced interest in pediatrics from the intervention group indicates that creating a learning environment personally relevant to students' careers facilitates interest to learn.

A total of 736 patients with fever was tested for malaria and classified according to ABO blood group. Of these, 476 cases had patent parasitaemia at the time of investigation. The distribution of blood groups in this group was significantly different from that in 1300 controls from the same area. While group A was found to be more common in malaria cases than in normals, the reverse situation was found for group O. Possible explanations for this are discussed. PMID:6971187

General anesthesia draws attention to the most commonly used modalities for post cesarean delivery pain relief in systemic administration of opioids, while the administration of small dose of intrathecal opioid during spinal anesthesia can be a possible alternative. The aim of this study was to evaluate the effects of buprenorphine on cesarean section prescribed intrathecally. This double blind randomized clinical trial study was conducted in patients for cesarean section under spinal anesthesia. The patients were randomly divided into case and control groups. Case group (208 patients) received 65-70 mg of 5% lidocaine plus 0.2 ml of buprenorphine while the same amount of 5% lidocaine diluted with 0.2 ml of normal saline was given to 234 cases in the control group. Hemodynamic changes and neonatal APGAR scores (Appearance, Pulse, Grimace, Activity, Respiration) were recorded. Pain score was recorded according to the visual analog scale. This study was registered in the Iranian Registry of clinical Trials; IRCT2013022112552N1. The mean age of case and control groups was 24.4±5.38 and 26.84±5.42 years, respectively. Systolic blood pressure was not significantly different until the 45th minute but diastolic blood pressure showed a significant difference at the 15th and the 60th minutes (P<0.001). Heart rate changes were significantly different between cases and controls at the initial 5th, 15th and after 60th minutes (P<0.001). Pain-free period was significantly different between two groups (1.25 h versus 18.73 h) (P<0.001). The results show that prescription of intratechal buprenorphine prolongs the duration of analgesia without any significant considerable side effects.

Introduction: The human papilloma virus (HPV) can play a role in the development of head and neck squamous cell carcinoma (SCC). Our aim was to assess the prevalence of HPV DNA in SCC of the larynx. The impact of HPV infection on patient survival was also evaluated. Materials and Methods: This case-control study was performed in 44 patients with SCC of the larynx (case group), while the control group comprised samples obtained from cadavers with no previous history of malignancy. A preliminary pathologic evaluation was performed on all samples in the control group (36 samples) to ensure the absence of dysplasia or malignancy. Polymerase chain reaction (PCR) was used to detect HPV DNA. After completing the treatment protocol, patients were followed to assess the impact of HPV infection on overall survival (OS). Results: PCR evaluation in the case group showed that HPV DNA was successfully isolated from 11 (25%) samples, while only two (5.6%) HPV DNA-positive were obtained from cadavers. According to these results, a significant difference was obtained in the prevalence of HPV DNA and laryngeal SCC between cases and controls (P=0.031). No statistically significant difference was observed in the OS of patients with or without HPV infection in the case group (P=0.235). Conclusion: Based on these results, we suggest that the prevalence of HPV infection is higher in laryngeal SCC subjects compared with healthy individuals. Although a longer OS was seen in HPV-positive patients, survival analysis did not show a significant difference in the comparison of HPV-positive and negative findings in SCC patients. PMID:27429948

To assess the clinical outcomes and costs associated with robotic single-site (RSS) surgery compared with those of conventional laparoscopy (CL) in gynecology. Retrospective case-control study (Canadian Task Force classification II-2). University-affiliated community hospital. Female patients undergoing RSS or CL gynecologic procedures. Comparison of consecutive RSS gynecologic procedures (cases) undertaken between October 2013 and March 2014 with matched CL procedures (controls) completed during the same time period by the same surgeon. Patient demographic data, operative data, and hospital financial data were abstracted from the electronic charts and financial systems. An incremental cost analysis based on the use of disposable equipment was performed. Total hospital charges were determined for matched RSS cases vs CL cases. RSS surgery was completed in 25 out of 33 attempts; 3 cases were aborted before docking, and 5 were converted to a multisite surgery. There were no intraoperative complications or conversions to laparotomy. The completed cases included 11 adnexal cases and 14 hysterectomies, 3 of which included pelvic lymph node dissection. Compared with the CL group, total operative times were higher in the RSS group; however, there were no significant between-group differences in estimated blood loss, length of hospital stay, or complication rates. Disposable equipment cost per case, direct costs, and total hospital charges were evaluated. RSS was associated with an increased disposable cost per case of $248 to $378, depending on the method used for vaginal cuff closure. The average total hospital charges for matched outpatient adnexal surgery were $15,450 for the CL controls and $18,585 for the RSS cases (p < .001), and the average total hospital charges for matched outpatient benign hysterectomy were $14,623 for the CL controls and $21,412 for the RSS cases (p < .001). Although RSS surgery and CL have comparable clinical outcomes in selected patients, RSS surgery remains associated with increased incremental disposable cost per case and total hospital charges. Careful case selection and judicious use of equipment are necessary to maximize cost-effectiveness in RSS gynecologic surgery. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

Objective: To explore the characteristics and methods of different fixation methods and prevention of open knee joint fracture. Methods: The data of 86 cases of open knee joint fracture admitted from January 2002 to December 2015 in Department of Orthopaedics, Affiliated Hospital of Chengdu University were analyzed retrospectively.There were 65 males and 21 females aged of 38.6 years. There were 38 cases treated with trans articular external fixation alone, 48 cases were in the trans articular external fixation plus auxiliary limited internal fixation group. All the patients were treated according to the same three stages except for different fixation methods. Observation of external fixation and fracture fixation, fracture healing, wound healing and treatment, treatment and related factors of infection control and knee function recovery. χ(2) test was used to analyze data. Results: Eleven patients had primary wound healing, accounting for 12.8%. Seventy-five patients had two wounds healed, accounting for 87.2%. Only 38 cases of trans articular external fixator group had 31 cases of articular surface reduction, accounting for 81.6%; Five cases of trans articular external fixator assisted limited internal fixation group had 5 cases of poor reduction, accounting for 10.4%; There was significant difference between the two groups (χ(2)=44.132, P <0.05). Take a single cross joint external fixation group, a total of 23 cases of patients with infection, accounted for 60.5% of external fixation group; trans articular external fixation assisted limited internal fixation group there were 30 cases of patients with infection, accounting for the assistance of external fixator and limited internal fixation group 62.5%; There was significant difference between the two groups(χ(2)=0.035, P >0.05). Five cases of fracture nonunion cases of serious infection, patients voluntarily underwent amputation. The Lysholm Knee Scale: In the external fixation group, 23 cases were less than 50 points, accounting for 60.5%, 15 cases were more than 50 points, accounting for 39.5%, external fixation and limited internal fixation group 20 cases were less than 50 points, accounting for 41.7%, 28 cases were more than 50 points, accounting for 58.3%; There was significant difference between the two groups(χ(2)=1.279, P >0.05). Conclusions: Prevention and control of infection is a central link in the treatment of open fracture of the knee. Trans articular external fixator plus limited internal fixation is an important measure to treat open fracture of the knee-joint.

Emotional intelligence has a major role in mental health and life skills training, and could be viewed as a bridge relating to emotional intelligence and mental health. The present study is aimed at determining the effect of life skills training on the emotional intelligence among the first year students of Mazandaran University of Medical Sciences. MATERIALS AND METHODS: IN THIS EXPERIMENTAL STUDY, THE SUBJECTS WERE SELECTED BY RANDOM SAMPLING AND ALLOCATED INTO TWO GROUPS: Case group (n=20) and control group (n=19); they matched for gender, experience of stressful life events in the past six months, level of interest in the field of study, and level of emotional intelligence. The two groups responded to Bar-on Emotional Quotient Inventory before starting the experiment. Subsequently, the case group underwent life skills training. After the training, Bar-on Emotional Quotient Inventory was responded by the case and control groups again. The data was analyzed using descriptive statistics including Chi-square test, paired and independent t-tests, using SPSS software version 15. In the case group, the scores of emotional intelligence after life skills training were significantly improved (t=11.703 df=19 P=0.001), while no significant difference was observed in the control group (t=0.683 df =18 P=0.503). By performing programs such as life skills training, the levels of emotional intelligence of the students could be increased, which itself could lead to academic success, reduced substance abuse, and increased stress tolerance in the students.

Case-based collaborative learning (CBCL) is a novel small-group approach that borrows from team-based learning principles and incorporates elements of problem-based learning (PBL) and case-based learning. CBCL includes a preclass readiness assurance process and case-based in-class activities in which students respond to focused, open-ended questions individually, discuss their answers in groups of 4, and then reach consensus in larger groups of 16. This study introduces CBCL and assesses its effectiveness in one course at Harvard Medical School. In a 2013 randomized controlled trial, 64 medical and dental student volunteers were assigned randomly to one of four 8-person PBL tutorial groups (control; n = 32) or one of two 16-person CBCL tutorial groups (experimental condition; n = 32) as part of a required first-year physiology course. Outcomes for the PBL and CBCL groups were compared using final exam scores, student responses to a postcourse survey, and behavioral coding of portions of video-recorded class sessions. Overall, the course final exam scores for CBCL and PBL students were not significantly different. However, CBCL students whose mean exam performance in prior courses was below the participant median scored significantly higher than their PBL counterparts on the physiology course final exam. The most common adjectives students used to describe CBCL were "engaging," "fun," and "thought-provoking." Coding of observed behaviors indicated that individual affect was significantly higher in the CBCL groups than in the PBL groups. CBCL is a viable, engaging, active learning method. It may particularly benefit students with lower academic performance.

This study aims to investigate Saccharomyces boulardii CNCM I-745 during Helicobacter pylori eradication in children. One hundred ninety-four H. pylori positive children were randomized in two groups. Therapy (omeprazole+clarithromycin+amoxicillin or omeprazole+clarithromycin+metronidazole in case of penicillin allergy) was given to both groups during two weeks. In the treatment group (n: 102) S. boulardii was added to the triple therapy, while the control group (n: 92) only received triple therapy. The incidence, onset, duration and severity of diarrhea and compliance to the eradication treatment were compared. A (13)C urea breath test was done 4 weeks after the end of eradication therapy in two groups of 21 patients aged 12 years and older to test the H. pylori eradication rate. In the treatment group, diarrhea occurred in 12 cases (11.76%), starting after 6.25±1.24 days, lasting 3.17±1.08 days, and compliance to eradication treatment was 100%. In the control group, diarrhea occurred in 26 cases (28.26%), starting after 4.05±1.11 days, lasting 4.02±0.87 days, and in six cases eradication treatment was stopped prematurely (p<0.05). The (13)C urea breath test showed successful H. pylori eradication in 71.4% of the patients in the treatment and in 61.9 % in the control group (not significant). S. boulardii has a beneficial effect on the prevention and treatment of diarrhea during H. pylori eradication in children. Although S. boulardii did only slightly increase H. pylori eradication rate, compliance to eradication treatment was improved.

The aim of our study was to evaluate the role of auras in preventing motor vehicle accidents (MVAs) among patients with medically refractory epilepsy. The Multicenter Study of Epilepsy Surgery database was used to perform a case-control study by identifying patients who had seizures while driving that led to MVAs (cases) and those who had seizures while driving without MVAs (controls). We compared presence of reliable auras and other aura-related features between the two groups. Two hundred fifteen of 553 patients reported having seizure(s) while driving; 74 were identified as "controls" and 141 as "cases." The two groups had similar demographic and clinical features. The presence of reliable auras was not different between the two groups (67% in cases vs. 65% in controls; odds ratio [OR] 0.89, 95% confidence interval [CI] 0.49-1.61, p = 0.76). In addition, the groups did not differ in the proportion of patients who reported longer (>1 min) auras (OR 0.7, 95% CI 0.28-1.76, p = 0.47), or who thought that their auras were of sufficient duration to be protective (OR 1.19, 95% CI 0.62-2.00, p = 0.77). Our study questions the long-held belief of a protective role of reliable auras against MVAs in people with epilepsy. Wiley Periodicals, Inc. © 2015 International League Against Epilepsy.

The objective of this study was to explore the effects of proton pump inhibitors (PPIs) on the development and prognosis of lung cancer precise radiotherapy-induced radiation pneumonitis. Clinical materials of 84 lung cancer patients who had radiation pneumonitis after precise radiotherapy were retrospectively analyzed, and the patients were divided into PPI group and control group, according to whether or not PPIs were applied. The development and prognosis of patients and the effects of different doses of PPI on patient condition from two groups were compared. There were 57 PPI cases in PPI group and 27 cases in control group. Basic characteristics of patients were not statistically different between the two groups; however, white blood cell count, oxygenation indexes, blood gas pH, and lung imaging index were significantly different (p < 0.05), indicating that radiation pneumonitis tended to be more severe in PPI group. As regards effects of PPI on prognosis of two groups, remission rate of radiation pneumonia in PPI group was significantly less than that of the control group. Among 57 cases in PPI group, there were 31 patients applied with PPI ≤ 1DDD and 31 patients applied with PPI > 1DDD. In comparison of the various parameters of patients, 7 days after being applied with different doses of PPI, there were no significant differences between the parameters of radiation pneumonitis. PPIs should be cautiously utilized to avoid the effects of lung cancer radiotherapy-induced radiation pneumonia.

Background Sudden sensorineural hearing loss (SSNHL) is a relatively common condition that is usually of unknown etiology. A number of individual studies have investigated the association between various serum lipids and SSNHL; however, the findings have been inconsistent. In an attempt to obtain more definitive information on the relationship between serum lipids and SSNHL, we carried out a systematic review and meta-analysis. Methods Medline, the Cochrane Library, and EMBASE were searched using the following key words: lipid, cholesterol, triglyceride, fat, serum, blood, sudden hearing loss, hearing loss, hearing disorders. Randomized controlled trials, prospective cohort studies, and retrospective case-control studies involving patients with SSNHL and healthy controls that examined the relationship (reported as odds ratios [OR]) between lipid profiles and SSNHL were included. Primary outcomes were total cholesterol and low-density lipoprotein cholesterol (LDL-C) concentrations. Secondary outcomes were triglyceride, high-density lipoprotein cholesterol, and lipoprotein(a) concentrations. Results A total of 6 case-control studies were included in this systematic review/meta-analysis. The total number of participants ranged from 30 to 250 in the case group and from 43 to 271 in the control group. Meta-analysis revealed no significant difference in total cholesterol levels between the case and control groups (pooled OR = 1.79, 95% confidence interval [CI] = 0.98 to 3.26, P = 0.057). Likewise, meta-analysis revealed no significant difference in LDL-C concentrations between the case and control groups (pooled OR = 1.15, 95% CI = 0.64 to 2.07, P = 0.639). Since there were an insufficient number of studies reporting data for the secondary outcomes, meta-analysis was not possible. Conclusions Our results do not provide evidence for serum lipids being associated with SSNHL, nor do they definitively rule out such an association. Additional studies are needed to ascertain the relationship, or lack thereof, between serum lipids and SSNHL. PMID:25866869

To compare the therapeutic effect of acupuncture for gastrointestinal neurosis with that of oral remedy. Eighty cases were randomly divided into the following 2 groups. In the treatment group, acupuncture was given for one month at the main points of Zhongwan (CV 12), Zusanli (ST 36), Taichong (LR 3) and Shenmen (HT 7), with the auxiliary points selected according to TCM differentiation. In the control group, Domperidone was orally administered for one month. The total effective rate was 92.5% in the treatment group and 75.0% in the control group, with a significant difference between the 2 groups (chi2 = 4.423, P < 0.05). Acupuncture was superior to the oral remedy in therapeutic effects. Acupuncture may show better results for gastrointestinal neurosis and with less toxic side effects.

We examined the changes of mean platelet volume (MPV) and platelet distribution width (PDW) in subjects with appendicitis and whether MPV and PDW could be used to predict the development of complication due to appendicitis. The healthy control group, the cases of appendicitis with perforation, and the cases of appendicitis without perforation were compared with regard to MPV and PDW. We determined whether MPV and PDW were independent variables predictive of the development of complication in subjects with appendicitis. This retrospective case-control study included a total of 362 patients (249 of which were male (68.8 %) and 113 were female (31.2 %); median age, 30 [range, 18-84 years]). One hundred and ninety-two subjects (53 %) presented with appendicitis and 170 (47 %) comprised the healthy control group. Sixty-six (18.2 %) of the subjects with appendicitis developed complication. MPVs were lower in subjects of appendicitis without complication compared to the subjects of appendicitis with complication and the control group (MPV, 9.78 ± 0.99 vs. 10.20 ± 1.21 and 10.14 ± 1.03, respectively [p = 0.005]). The PDW levels were not different between the three groups. Independent variables predictive of the presence of complication included increased MPV and time from onset of symptoms to hospital presentation (odds ratio[confidence interval], p-value: 1.507[1.064-2.133], 0.021 and 18.887[5.139-69.410], 0.0001, respectively). Our findings suggested these, MPV values in cases of appendicitis without complication were lower than the cases with complication and healthy control and MPV is a predictor of the development of complication in subjects with appendicitis.
Latex agglutination test (LAT) for the diagnosis of typhoid fever.
Sahni, Gopal Shankar
2013-06-01
The efficacy of latex agglutination test in the rapid diagnosis of typhoid fever was studied and the result compared with that of blood culture. This study included 80 children suffering from typhoid fever, among which 40 were confirmed by blood culture isolation and 40 had possible typhoid fever based on high Widal's titre (a four-fold rise in the titre of antibody to typhi "O" and "H" antigen was considered as a positive Widal's test result). Eighty children, 40 with febrile illness confirmed to be other than typhoid and 40 normal healthy children were used as negative controls. The various groups were: (i) Study group ie, group I had 40 children confirmed by culture isolation of Salmonella typhi(confirmed typhoid cases). (ii) Control groups ie, (a) group II with 40 febrile controls selected from paediatrics ward where cause other than S typhi has been established, (b) group III with 40 afebrile healthy controls that were siblings of the children admitted in paediatric ward for any reason with no history of fever and TAB vaccination in the last one year, and (c) group IV with 40 children with high Widal's titre in paired sera sample. Widal's test with paired sera with a one week interval between collections were done in all 40 patients. Latex aggtutination test which could detect 900 ng/ml of antigen as observed in checker board titration, was positive in all 40 children from group I who had positive blood culture and in 30 children from group IV who had culture negative and had high Widal's titre positive. Latex agglutination test was positive in 4 children in group II and none in group III. Using blood culture positive cases as true positive and children in groups II and III as true negative, the test had a sensitivity of 100% and specificity of 96%. Latex agglutination test was found to be significantly sensitive (100%) and specific (96%) and could detect 75% more cases in group IV (possible typhoid cases). Thus latex agglutination test can be used for rapid diagnosis of typhoid fever though it cannot replace conventional blood culture required for isolation of organism to report the antibiotic sensitivity.

Dengue Hemorrhagic Fever (DHF) is transmitted to humans by dengue virus harboring Aedes aegypti. Immune response against viral infection can be influenced by stress as stress could weaken immune response. Stress can cause illness through physiological changes and changes in immune function. The immunological changes associated with stress were adapted from the immunological changes in response to infection. The purpose of this study was to determine the relationship between DHF cases with stress level._We used a case control study with DHF sample cases from three hospitals in Semarang city (n=27) from the period of March to May 2017 and the control groups from healthy respondents with matched age, sex, and district location (n=27). The data was processed by Chi-Square test._Levels of stress were categorized into two namely high and low tress levels. The data was normally distributed. The frequency distribution in case group at high stress category were 15 respondents (55.6%) and low stress were 12 respondents (44.4%). Meanwhile, in control group there were 8 respondents (29.6%) at high stress category and 19 respondents (70.4%) at low stress category. The Chi Square Test revealed that the p value was 0,054 and OR was 2,969. In conclusion there was no relation between stress level and Dengue Hemorrhagic Fever cases.

Bilateral balloon occlusion has been employed as a prophylactic measure in cases of placenta accretism prior to caesarean section with the aim of reducing blood loss and its associated morbidity/mortality. There is however no clear consensus on its efficacy in the current literature. The objective of this study was to assess the efficacy of bilateral balloon occlusion of the common iliac arteries (CIA) in reducing intra-operative morbidity in cases of placenta accretism. The databases of the pathology department and radiology interventional suite were reviewed over a nine year period. Fifty-two cases of confirmed placental accretism who underwent caesarean section with or without hysterectomy were identified and divided into two groups. Twenty-five cases had temporary occlusion of the common iliac arteries (CIA) during delivery and these were considered the study group. The reminder 27 cases did not have temporary occlusion of the CIA and were considered the control group. The two groups were compared based on gravidity, age group, post-operative haemoglobin, drop in haemoglobin, estimated blood loss (EBL), transfusion requirement and the histopathological sub-types of placenta accretism. There was no statistically difference between the study and the control groups regarding EBL, post-operative haemoglobin drop, transfusion requirement or in the placenta accretism histopathological subtype. Two cases in the study group had acute thromboembolic complications. Both groups had a single patient requiring a massive intra-operative transfusion. Our study was not able to detect a significant difference in blood loss or blood product requirement between patients who underwent CIA balloon in the setting of caesarean section for placenta accreta. This remains a challenging scenario requiring a multidisciplinary approach. © 2016 The Royal Australian and New Zealand College of Radiologists.

Background Unmeasured confounding is one of the principal problems in pharmacoepidemiologic studies. Several methods have been proposed to detect or control for unmeasured confounding either at the study design phase or the data analysis phase. Aim of the Review To provide an overview of commonly used methods to detect or control for unmeasured confounding and to provide recommendations for proper application in pharmacoepidemiology. Methods/Results Methods to control for unmeasured confounding in the design phase of a study are case only designs (e.g., case-crossover, case-time control, self-controlled case series) and the prior event rate ratio adjustment method. Methods that can be applied in the data analysis phase include, negative control method, perturbation variable method, instrumental variable methods, sensitivity analysis, and ecological analysis. A separate group of methods are those in which additional information on confounders is collected from a substudy. The latter group includes external adjustment, propensity score calibration, two-stage sampling, and multiple imputation. Conclusion As the performance and application of the methods to handle unmeasured confounding may differ across studies and across databases, we stress the importance of using both statistical evidence and substantial clinical knowledge for interpretation of the study results.

The role of bacteria is unclear in the facial skin lesions caused by Demodex. To shed some light on this issue, we conducted a case-control study comparing cases with facial dermatoses with controls with healthy skin using denaturing gradient gel electrophoresis (DGGE) technique. The bacterial diversity, composition, and principal component were analyzed for Demodex bacteria and the matched facial skin bacteria. The result of mite examination showed that all 33 cases were infected with Demodex folliculorum (D. f), whereas 16 out of the 30 controls were infected with D. f, and the remaining 14 controls were infected with Demodex brevis (D. b). The diversity analysis showed that only evenness index presented statistical difference between mite bacteria and matched skin bacteria in the cases. The composition analysis showed that the DGGE bands of cases and controls were assigned to 12 taxa of 4 phyla, including Proteobacteria (39.37-52.78%), Firmicutes (2.7-26.77%), Actinobacteria (0-5.71%), and Bacteroidetes (0-2.08%). In cases, the proportion of Staphylococcus in Firmicutes was significantly higher than that in D. f controls and D. b controls, while the proportion of Sphingomonas in Proteobacteria was significantly lower than that in D. f controls. The between-group analysis (BGA) showed that all the banding patterns clustered into three groups, namely, D. f cases, D. f controls, and D. b controls. Our study suggests that the bacteria in Demodex should come from the matched facial skin bacteria. Proteobacteria and Firmicutes are the two main taxa. The increase of Staphylococcus and decrease of Sphingomonas might be associated with the development of facial dermatoses.

To explore the correlation between the degree of bone marrow edema (BME) and the content change of tumor necrosis factor alpha (TNF-alpha) and matrix metalloproteinase 3 (MMP-3) and the knee pain symptoms in patients with bone contusion around the knee joint. Thirty patients (30 knees) of bone contusion around the knee joint were chosen as the trial group between October 2009 and April 2012. According to visual analogue scale (VAS), 30 patients were divided into mild group (10 cases), moderate group (10 cases), and severe group (10 cases); according to MRI morphological changes, the patients were divided into type I group (12 cases), type II group (11 cases), and type III group (7 cases). Ten patients (10 knees) with soft tissue injury of the knee were chosen as control group. No significant difference was found (P > 0.05) in gender, age, causes, side, and admission time after injury between 2 groups. The serum contents of MMP-3 and TNF-alpha were detected and statistically analysed between different degrees of pain groups and between different degrees of BME groups. Correlation was analysed between BME and inflammatory factor changes and VAS score. The MMP-3 and TNF-alpha contents in trial group [(29.580 +/- 6.870) (microg/L and (23.750 +/- 7.096) ng/L] were significantly higher than those in control group [(8.219 +/- 1.355) microg/L and (6.485 +/- 1.168) ng/L] (t = 9.686, P = 0.000; t = 7.596, P =0.000). The MMP-3 and TNF-alpha contents in patients with different degrees of pain and BME were significantly higher than those in patients of control group (P < 0.05), and significant difference was found between patients with different degrees of pain (P < 0.05), but no significant difference between patients with different degrees of BME (P > 0.05). Multiple linear regression analysis showed that TNF-alpha content was significantly correlated with VAS score (P = 0.000). Knee pain symptoms are not related to the degree of BME in patients with bone contusion around the knee joint. Inflammatory factor TNF-alpha content is the main influence factor of knee joint pain symptoms.

The purpose of the study was to determine the advantages and disadvantages of prophylactic/extended colectomy (subtotal colectomy) in patients with Lynch syndrome who manifest colorectal cancer. A retrospective cohort using Creighton University's hereditary cancer database was used to identify cases and controls. Cases are patients who underwent subtotal colectomy, either with no colorectal cancer diagnosis (prophylactic) or at diagnosis of first colorectal cancer; controls for these 2 types of cases were, respectively, patients who underwent no colon surgery or those having limited resection at time of diagnosis of first colorectal cancer. The Kaplan-Meier and proportional hazard regression models from the Statistical Analysis Software program was used to calculate the difference in survival, time to subsequent colorectal cancer, and subsequent abdominal surgery between cases and controls. The event-free survival of our study did not reach 50%, so we used the event-free survival at 5 years as our parameter to compare the 2 groups. The event-free survival for subsequent colorectal cancer, subsequent abdominal surgery, and death was 94%, 84%, and 93%, respectively, for cases and 74%, 63%, and 88%, respectively, for controls. Times to subsequent colorectal cancer and subsequent abdominal surgery were significantly shorter in the control group (P < .006 and P < .04, respectively). No significant difference was identified with respect to survival time between the cases and controls. Even though no survival benefit was identified between the cases and controls the increased incidence of metachronous colorectal cancer and increased abdominal surgeries among controls warrant the recommendation of subtotal colectomy in patients with Lynch syndrome.

The case-control study reported here evaluated the protective effect of BCG vaccine against leprosy in São Paulo, Brazil. Seventy-eight patients under age 16 who had been diagnosed as having leprosy (cases) and 385 healthy individuals (controls) were selected and matched by sex, age, place of residence, and type of exposure to leprosy (intradomiciliary or extradomiciliary). The cases were drawn from an active patient registry and from a group of new leprosy cases treated at 50 health centers in the cities of Bauru and Ribeirão Preto in the state of São Paulo. In order to estimate the protective effect of BCG, the prevalences of BCG scars in cases and controls were compared. The presence of one or more scars was associated with an estimated protective efficacy of 90% (95% confidence interval: 78% to 96%). Stratified analysis by age group, sex, socioeconomic level, and clinical form of the disease revealed no significant differences in the protection provided by the vaccine. However, it seems clear that more data will be needed in order to accurately assess the true relevance of BCG for leprosy control programs.

This study aimed to estimate the population-attributable risks (PARs) of 9 major risk factors for stroke in Korea through a case-control study and to test the feasibility and validity of internet-based control recruitment. From April 2008 to September 2009, controls were enrolled via internet after providing consent for participation through a web-based survey. The cases included patients who were admitted to the participating centers due to acute stroke or transient ischemic attack within 7 days of onset during the study period. Each control was age- and sex-matched with 2 cases. Adjusted odd ratios, age-standardized prevalence, and PARs were estimated for the 9 major risk factors using the prevalence of risk factors in the control group and the age and sex characteristics from Korea's national census data. In total, 1041 controls were matched to 2082 stroke cases. Because of a shortage of elderly controls in the internet-based recruitment, 248 controls were recruited off-line. The PARs were 23.44%, 10.95%, 51.32%, and 6.35% for hypertension, diabetes, smoking, and stroke history, respectively. Hypercholesterolemia, atrial fibrillation, obesity, coronary heart disease, and a family history of stroke were not associated with stroke. Comparison with education and religion of the control group with that mentioned in the national census data showed a notable difference. The study results imply that internet-based control recruitment for a case-control study requires careful selection of risk factors with high self-awareness and effective strategies to facilitate the recruitment of elderly participants.

Multiple congenital abnormalities are caused by chromosomal aberrations, mutant major genes and teratogens. A minor proportion of these patients are identified as syndromes but the major part belonging to the group of unclassified multiple CAs (UMCAs). The main objective of this study was to evaluate the maternal age and birth order in pregnant women who had offspring affected with UMCA. The strong association between numerical chromosomal aberrations, e.g., Down syndrome and advanced maternal age is well-known and tested here. The Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980 to 1996, yielded a large population-based national data set with 22,843 malformed newborns or fetuses ("informative cases") included 1349 UMCA cases with their 2407 matched controls. Case-control comparison of maternal age and birth order was made for cases with UMCA, stratified by component numbers and their controls. In addition, 834 cases with Down syndrome were compared to 1432 matched controls. The well-known advanced maternal age with the higher risk for Down syndrome was confirmed. The findings of the study suggest that the young age of mothers associates with the higher risk of UMCA, in addition birth order 4 or more associates with the higher risk for UMCA with 2 and 3 component CAs. This study was the first to analyze the possible maternal and birth order effect for cases with UMCA, and the young age and higher birth order associated with a higher risk for UMCA. © 2014 Wiley Periodicals, Inc.

We investigated the possible correlations between N-acetyltransferase-2 (NAT2) gene polymorphisms and the risk of coronary heart disease (CHD). CHD patients (113) and healthy controls (118) were enrolled from the First People's Hospital of Yuhang between January 2013 and June 2014. The patients were divided into mild CHD (N = 72) and severe CHD (N = 41) subgroups. DNA samples were extracted and the distributions of NAT2 polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Clinical characteristic indexes of severe CHD patients were also examined for relevant statistical analysis. WT, M1, M2, and M3 alleles were observed in both case and control groups. PCR-RFLP identified a wild-type homozygote, WT/WT; a mutant heterozygote, WT/Mx; and a mutant homozygote, Mx/Mx (x = 1, 2, and 3) variant of the NAT2 genotype. Mx/Mx differed significantly between case and control groups (P < 0.05); the frequencies of all four alleles did not differ significantly between case and control groups (P > 0.05). Slow acetylator genotype frequencies were notably higher in the case group than in the control group (P < 0.05). Individuals with the slow acetylator genotype were at 1.97-times higher risk of CHD and also displayed higher triglyceride and lower high-density lipoprotein cholesterol levels than those with the rapid acetylator genotype (P < 0.05). Therefore, the NAT2 polymorphism was believed to be associated with increased risk of CHD, with the NAT2 slow acetylator genotype serving as a risk factor for severe CHD in a Chinese population.

To evaluate the effectiveness of two doses of a monovalent rotavirus vaccine (RV1) against hospital admission for rotavirus in Bolivia. Case-control study. Six hospitals in Bolivia, between March 2010 and June 2011. 400 hospital admissions for rotavirus, 1200 non-diarrhea hospital controls, and 718 rotavirus negative hospital controls. Odds of antecedent vaccination between case patients and controls; effectiveness of vaccination ((1-adjusted odds ratio)×100), adjusted for age and other confounders; and stratified effectiveness by dose, disease severity, age group, and serotype. In comparison with non-diarrhea controls, case patients were more likely to be male and attend day care but less likely to have chronic underlying illness, higher level maternal education, and telephones and computers in their home. Rotavirus negative controls were somewhat more similar to case patients but also were more likely to be male and attend day care and less likely to have higher level maternal education and computers in their homes. The adjusted effectiveness of RV1 against hospital admission for rotavirus was 69% (95% confidence interval 54% to 79%) with rotavirus negative controls and 77% (65% to 84%) with non-diarrhea controls. The effectiveness of one dose of RV1 was 36% and 56%, respectively. With both control groups, protection was sustained through two years of life, with similar efficacy against hospital admission among children under 1 year (64% and 77%) and over 1 year of age (72% and 76%). RV1 provided significant protection against diverse serotypes, partially and fully heterotypic to the G1P[8] vaccine. Effectiveness using the two control groups was 80% and 85% against G9P[8], 74% and 93%% against G3P[8], 59% and 69% against G2P[4], and 80% and 87% against G9P[6] strains. The monovalent rotavirus vaccine conferred high protection against hospital admission for diarrhea due to rotavirus in Bolivian children. Protection was sustained through two years of life against diverse serotypes different from the vaccine strain.

To evaluate cytopathological changes in epithelial cells of the oral mucosa of patients with oral lichen planus (OLP) compared with patients without OLP. Swabs were collected from the oral mucosa of 20 patients with OLP (case group) and 20 patients without OLP (control group) using liquid-based cytology. After Papanicolaou staining, the smears were characterized based on Papanicolaou classification and degree of maturation. Nuclear area (NA) measurements, cytoplasmic area (CA) measurements, and the NA/CA ratio were determined from 50 epithelial cells per slide. For quantification of argyrophilic nucleolar organizer regions (AgNORs), the smears were stained with silver nitrate, and the number of AgNORs was counted in 100 cells. In both groups, there was a predominance of Papanicolaou Class I nucleated cells in the superficial layer. The average values of NA (p>0.05) and CA (p=0.000) were greater in the case group (NA=521.6, CA=22,750.3) compared with the control group (NA=518.9, CA=18,348.0). The NA/CA ratio was 0.025 for the case group and 0.031 for the control group (p=0.004). There was no significant difference between the mean AgNORs values of both groups (p>0.05). The oral mucosa of patients with OLP exhibited significant cytomorphometric changes. However, there was no evidence of malignancy. Copyright © 2016 Elsevier GmbH. All rights reserved.

To observe the clinical therapeutic effect of OM-85 BV(OM-85 Broncho-Vaxom) in children with asthma and recurrent respiratory tract infection, and the effect of OM-85 BV on human β-defensins 1 (hBD-1) and immunoglobulin levels. Sixty-two children with asthma and recurrent respiratory infection treated between 2011 January and December were divided into two groups by the randomized, double blind method: a treatment group and a control group. With inhaling corticosteroids, the treatment group was given OM-85 BV, and the control group was given a placebo. Clinical curative effects and adverse reactions were observed. Serum levels of hBD-1, IgA, IgG, IgM and urea and alanine aminotransferase (ALT) were measured before treatment and 6 months and 12 months after treatment. Compared with the control group and before treatment, the frequency of respiratory tract infection was reduced in the treatment group 6 months and 12 months after treatment (P<0.05), and serum levels of hBD-1, IgA and IgG in the treatment group increased significantly (P<0.05). There was no significant difference in serum levels of urea, ALT and IgM between the control and treatment groups (P>0.05). Mild adverse reactions occurred in 3 cases in the two groups, 2 cases of abdominal pain and 1 cases of constipation. OM-85 BV can improve serum levels of hBD-1, IgA and IgG, reduce the occurrence of acute respiratory tract infection and cause mild adverse reactions, suggesting its satisfactory therapeutic effect and safety in the treatment of asthma combined with recurrent respiratory tract infection in children.

The objective of the present study was to determine oxidant and antioxidant status in infants with hyperbilirubinemia and/or kernicterus and to find whether there is a relationship between bilirubin level and oxidant/antioxidant status. The study includes 69 full-term newborns (neonates with hyperbilirubinemia needing phototherapy [Group 1, n = 36] and neonates with kernicterus [Group 2, n = 33]) and 25 age-matched healthy newborn. Plasma total antioxidant capacity (TAC) and serum total oxidant status (TOS) were significantly higher in Groups 1 and 2 than the control group. There was a significant difference between Group 1 and control cases for malondialdehyde (MDA; p < 0.001). Total free sulfhydryl group (TTHI) values were significantly elevated in Group 1 compared to Group 2 and control cases. Correlation analysis showed that the correlation between total bilirubin (TB) and TAC, TOS, MDA and oxidative stress index may be expressed by a quadratic curve. After phototherapy, a statistically significant increase in nitrite level was observed. We demonstrated that the relationship between serum TB and antioxidants and oxidative stress could be expressed by a quadratic correlation curve.

Placenta previa (PP) is a potential life-threatening pregnancy complication. Pro-brain natriuretic peptide (ProBNP), creatine kinase (CK), cardiac form of CK (CK-MB) and Troponin I are circulatory biomarkers related to cardiac functions. We aimed to determine whether these biomarkers are related to PP and placenta accreta. In this case-control study, fifty-four pregnant women who attended our tertiary care center for perinatology with the diagnosis of PP totalis, and of them, 14 patients with placenta accreta were recruited as the study groups. Forty-six uncomplicated control patients who were matched for age, BMI were also included. Maternal venous ProBNP, CK, CK-MB and Troponin I levels were compared between the three groups. Obstetric history characteristics were comparable among groups, generally. CK and CK-MB levels were similar among three groups. Troponin I levels in the previa and accreta groups were significantly higher than the controls. ProBNP levels in the accreta group were significantly higher than other two groups. The multivariate regression model revealed that ProBNP could predict placental adhesion anomalies. Troponin I and ProBNP levels in PP cases were higher than controls and ProBNP could predict placenta accreta.

A case-control study of chronic neurological and psychiatric disease and occupational exposure to solvents was carried out in eight automobile assembly plants. Cases included 299 subjects who were granted medical disability retirement in 1980-8. Two control groups were selected, the first from those granted retirement in the same period because of medical disability from causes unrelated to solvent exposure. The second included hourly employees from the plant population. In these facilities, solvent exposures tended to be short term and low level, although common: the average duration of exposure was 2.3 years; about 41% experienced at least one day of exposure. Of those exposed, 46% had less than one year of exposure. Results for all psychiatric disease combined (273 cases) suggested that cases had lower exposures than either control group, regardless of how exposure was expressed. Results could not be explained by conventional confounding exposures or characteristics or by usual manifestations of the healthy worker effect. By contrast, chronic neurological disease, and multiple sclerosis in particular, seemed to be associated with exposure, although few cases were identified and observed increases in risk were not statistically significant.

This study evaluated the diagnostic performance of the atopy patch test (APT) compared with skin prick testing (SPT) and in vitro IgE measurement in a large group of patients with atopic dermatitis (AD) with or without respiratory symptoms (RS). The study included 521 patients (292 males, 229 females; age, 0.5-18 years; median age, 6 years) with AD and RS with different clinical presentations: current AD, 47 patients (Group A); current AD and RS, 72 patients (Group B), past AD and RS, 69 patients (Group C); and RS only, 280 patients (Group D). Fifty-three healthy individuals served as controls. All participants underwent the APT, SPT, and CAP/RAST with the most common inhalant allergens. The presence of a control group allowed calculation of specificity and positive and negative predictive values. A significant difference was found for a positive APT versus both SPT and CAP/RAST (P < .0001) but not for SPT versus CAP/RAST. The differences for APT were significant in all group comparisons except group B vs C and group C vs D. In the control group, the APT was positive in 2% of cases (specificity of 96.2%), SPT was positive in 6% of cases (specificity of 88.4%), and CAP/RAST was positive in 4% of cases (specificity of 92.5%). In young patients sensitized to inhalant allergens with AD in addition to RS, the APT has a superior diagnostic performance to SPT and in vitro IgE measurement.

This two-part quasi-experimental repeated measures study examined whether computer simulated experiments have an effect on the problem solving skills of high school biology students in a school-within-a-school magnet program. Specifically, the study identified episodes in a simulation sequence where problem solving skills improved. In the Fall academic semester, experimental group students (n = 30) were exposed to two simulations: CaseIt! and EVOLVE!. Control group students participated in an internet research project and a paper Hardy-Weinberg activity. In the Spring academic semester, experimental group students were exposed to three simulations: Genetics Construction Kit, CaseIt! and EVOLVE! . Spring control group students participated in a Drosophila lab, an internet research project, and Advanced Placement lab 8. Results indicate that the Fall and Spring experimental groups experienced significant gains in scientific problem solving after the second simulation in the sequence. These gains were independent of the simulation sequence or the amount of time spent on the simulations. These gains were significantly greater than control group scores in the Fall. The Spring control group significantly outscored all other study groups on both pretest measures. Even so, the Spring experimental group problem solving performance caught up to the Spring control group performance after the third simulation. There were no significant differences between control and experimental groups on content achievement. Results indicate that CSE is as effective as traditional laboratories in promoting scientific problem solving and that CSE is a useful tool for improving students' scientific problem solving skills. Moreover, retention of problem solving skills is enhanced by utilizing more than one simulation.

High-fidelity patient simulation (HFPS) has been used in medical education to bridge gaps in medical knowledge and clinical skills. Few studies have analyzed the impact of HFPS in subspecialty rotations for pediatric residents. We hypothesized that pediatric residents exposed to HFPS with a structured content curriculum would perform better on a case quiz than residents without exposure to HFPS. Prospective randomized controlled Tertiary-care free standing children's hospital During a cardiology rotation, senior pediatric residents completed an online pediatric cardiology curriculum and a cardiology quiz. After randomization into two groups, the study group participated in a fully debriefed HFPS session. The control group had no HFPS. Both groups completed a case quiz. Confidence surveys pre- and postsimulation were completed. From October 2010 through March 2013, 55 residents who rotated through the pediatric cardiology rotation were used in the final analysis (30 control, 25 in the study group). There was no significant difference between groups on the initial cardiology quiz. The study group scored higher on the case quiz compared with the control group (P = .024). Based on pre- and postsimulation questionnaires, residents' confidence in approaching a pediatric cardiology patient improved from an average Likert score of 5.1 to 7.5 (on scale of 0-10) (P < .001). Incorporation of HFPS into a preexisting pediatric cardiology rotation was feasible and well received. Our study suggests that simulation promotes increased confidence and may modestly improve clinical reasoning compared to traditional educational techniques. Targeted simulation sessions may readily be incorporated into pediatric subspecialty rotations. © 2014 Wiley Periodicals, Inc.

The purpose of this study is to investigate the effect of Shenfu injection (SFI) on the tumor necrosis factor-α (TNF-α) and the interleukin (IL-6, IL-8, IL-10) of elderly patients who suffered from severe pneumonia. From June 2012 to September 2014, we performed in our department 89 cases of elderly patients with severe pneumonia. These patients were randomly divided into two groups: the treatment group (45 cases) and the control group (44 cases). The control group was given the treatment of anti-infection, reducing sputum, and support therapy, while the treatment group was fed by SFI intravenously based on the control group. The TNF-α and the interleukin were detected by enzyme-linked immunosorbent assay (ELISA). Meanwhile, the changes in the inflammatory response indicators, the blood gas analysis, and the parameters of vital signs were measured and compared before and after therapy. Prior to treatment, there is no significant difference between the treatment group and the control group (p > 0.05); after the treatment for 7 days, the levels of TNF-α, IL-6, and IL-8 were significantly decreased, while the level of IL-10 was obviously increased. The APACHE II score was significantly decreased in comparison to that before the treatment (p < 0.05), and the time of mechanical ventilation, the duration of time in ICU, and the application time of vasoactive drugs were notably shortened. The application of Shenfu injection exhibited a positive and effective effect on removing the inflammation media during the treatment of elderly severe pneumonia.

Supernumerary nipples (SNN), or polythelia, are the most common form of the accessory mammary tissue malformation. The frequency of this condition ranges from 0.2% to 5.6% depending on various factors. This condition is associated with several anomalies, although this association is often controversial. The aim of this study was to evaluate the association between SNN and kidney/urinary tract (K/UT) anomalies, where anomalies is taken to mean functional disorders, malformations and diseases. A case-control study was performed. The study evaluated 166 children (case group) referred to the Pediatric Nephrology Unit of the Department of Pediatrics of the Catholic University of Rome and 182 children (control group) admitted to the Department of Pediatrics because of pathologies not involving the urinary tract. There were 11 children with SNN in the case group, and only two patients in the control group (6.62% vs 1.09%, p<0.05). The results show a high incidence of K/UT anomalies in children with SNN, and therefore K/UT should be investigated in this specific population.

Involvement of community mental health consumers in mental health decision making has been consistently associated with improvements in health outcomes. Electronic decision support systems (EDSSs) that support both consumer and provider decision making may be a sustainable way to improve dyadic communication in a field with approximately 50% workforce turnover per year. This study examined the feasibility of such a system and investigated proximal outcomes of the system's performance. A cluster randomized design was used to evaluate an EDSS at three urban community mental health sites. Case managers (N=20) were randomly assigned to the EDSS-supported planning group or to the usual care planning group. Consumers (N=80) were assigned to the same group as their case managers. User satisfaction with the care planning process was assessed for consumers and case managers (possible scores range from 1 to 5, with higher summary scores indicating more satisfaction). Recall of the care plan was assessed for consumers. Linear regression with adjustment for grouping by worker was used to assess satisfaction scores. A Wilcoxon rank-sum test was used to examine knowledge of the care plan. Compared with case managers in the control group, those in the intervention group were significantly more satisfied with the care planning process (mean ± SD score=4.0 ± .5 versus 3.3 ± .5; adjusted p=.01). Compared with consumers in the control group, those in the intervention group had significantly greater recall of their care plans three days after the planning session (mean proportion of plan goals recalled=75% ± 28% versus 57% ± 32%; p=.02). There were no differences between the clients in the intervention and control groups regarding satisfaction. This study demonstrated that clients can build their own care plans and negotiate and revise them with their case managers using an EDSS.

Introduction In Iran, after unintentional accidents, mental health problems are the second leading burden of disease. Consanguineous marriage is very common in Iran and the association between parental consanguinity and mental health is an important issue that has not yet been studied sufficiently in Iran. Aim To investigate the effect of consanguinity and the degree of relationship on different levels of mental health. Materials and Methods In this cross-sectional study, conducted in the Shahrekord University of Medical Sciences, two groups of students were enrolled. The first group consisted of 156 students that had consanguineous parent (case group) and the second group was 156 students whose parents had non-blood relationship (control group). The students were evaluated using General Health Questionnaire (GHQ-28). Statistical analysis was conducted by Pearson’s correlation coefficient, independent t-test and the one-way analysis of variance. Odd ratio was used to estimate the relative risk. Results Over 30% of the individuals were suffering from mental health problems. The most and least common mental health problems in both groups were social dysfunction (54.5% in the case group and the control group 50%) and depression (15.4% in the case group and 17.3% in the control group), respectively. No statistically significant difference was observed in the frequency of overall mental health and its subscales between student with non-consanguineous parent (control group) and the students that had consanguineous parent (case group) (p>0.05) and the status of mental health was not significantly different among student with different degree of kinship (p>0.05). Conclusion The study revealed that social dysfunction was very common among the study students and also there were no relationship between parental consanguineous marriage and mental health. Parental consanguinity and genetic factors may not be the major causes of high prevalence of mental health problems in Iran and the effects of the environmental factors on these problems may be greater than those of the inherited ones.

Open reduction and internal fixation of pelvic fractures could restore the stability of the pelvic ring, but there were several problems. Minimally invasive closed reduction cannulated screw treatment of pelvic fractures has lots advantages. However, how to insert the cannulated screw safely and effectively to achieve a reliable fixation were still hard for orthopedist. Our aim was to explore the significance of 3D printing technology as a new method for minimally invasive cannulated screw treatment of unstable pelvic fracture. One hundred thirty-seven patients with unstable pelvic fractures from 2014 to 2016 were retrospectively analyzed. Based on the usage of 3D printing technology for preoperative simulation surgery, they were assigned to 3D printing group (n = 65) and control group (n = 72), respectively. These two groups were assessed in terms of operative time, intraoperative fluoroscopy, postoperative reduction effect, fracture healing time, and follow-up function. The effect of 3D printing technology was evaluated through minimally invasive cannulated screw treatment. There was no significant difference in these two groups with respect to general conditions, such as age, gender, fracture type, time from injury to operation, injury cause, and combined injury. Length of surgery and average number of fluoroscopies were statistically different for 3D printing group and the control group (p < 0.01), i.e., 58.6 vs. 72.3 min and 29.3 vs. 37 min, respectively. Using the Matta radiological scoring systems, the reduction was scored excellent in 21/65 cases (32.3%) and good in 30/65 cases (46.2%) for the 3D printing group, versus 22/72 cases (30.6%) scored as excellent and 36/72 cases (50%) as good for the control group. On the other hand, using the Majeed functional scoring criteria, there were 27/65 (41.5%) excellent and 26/65 (40%) good cases for the 3D printing group in comparison to 30/72 (41.7%) and 28/72 (38.9%) cases for the control group, respectively. This suggests no significant difference between these two groups about the function outcomes. Full reduction and proper fixation of the pelvic ring and reconstruction of anatomical morphology are of great significance to patients' early functional exercise and for the reduction of long-term complications. This retrospective study has demonstrated the 3D printing technology as a potential approach for improving the diagnosis and treatment of pelvic fractures. The study was retrospectively registered at the Chinese Clinical Trial Registry, number: ChiCTR-TRC-17012798, trial registration date: 26 Sept. 2017.

To investigate the effect of Huanshuai Recipe Oral Liquid ([characters: see text], HSR) on retarding the progression of renal dysfunction in patients with atherosclerotic renal artery stenosis (ARAS). A total of 52 ARAS patients with the Chinese medicine (CM) syndrome of qi deficiency and blood stasis, phlegm and dampness retention were recruited and randomly assigned into the treatment group (36 cases) and the control group (16 cases). Both groups received a basic treatment (high-quality low-protein diet, blood pressure control, lipid-lowering, correcting the acidosis, etc.). In addition, the treatment group received 20 mL HSR and the control group received placebo, 3 times a day for 6 months. Renal function (serum creatinine, blood urea nitrogen and uric acid) and blood lipids (cholesterol, triglycerides and low density lipoprotein) were examined monthly. The estimated glomerular filtration rate (eGFR) and CM syndrome score were compared between groups. After treatment, compared with the control group, the serum creatinine level, uric acid level and CM syndrome score of the treatment group were significantly decreased (P<0.05 or P<0.01), and the eGFR in the treatment group were significantly increased (P<0.05). HSR can effectively improve the renal function and clinical symptoms of ARAS patients.

The aim of the current study was to observe the effects of Twenty-four Move Shadow Boxing combined with psychosomatic relaxation on depression and anxiety in patients with Type-2 Diabetes. One hundred and twenty (120) patients with Type-2 Diabetes and depressive/anxious symptoms were divided into intervention group (60 cases) and control group (60 cases) according to the minimum distribution principle of unbalanced indicators. Twenty-four Move Shadow Boxing group used this intervention combined with psychosomatic relaxation. Control group underwent conventional treatment. All the patients in the two groups completed the Self-rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) before and after treatment. Among the 52 people included in the statistical analysis, the recovery rate was 13.3%. The differences between depression and anxiety scores in the intervention group before and after treatment were statistically significant (P<0.001), whereas these differences were non-significant in the control group (P=0.123). After the treatment, the glycated hemoglobin reduction in the intervention group was greater than that of the control group (t=2.438, P=0.016). The combination of Twenty-four Move Shadow Boxing and psychosomatic relaxation has a beneficial auxiliary therapeutic effect on depression and anxiety accompanying Type-2 Diabetes.

Prevention of suicidal behaviour is a public health priority in the European Union. A previous suicide attempt is the best risk predictor for future attempts, as well as completed suicides. The primary aim of this article is to describe a controlled study protocol designed for prevention of recurrent suicidal behaviour that proposes case management, and includes a psychoeducation program, as compared with the standard intervention (PSyMAC). Patients admitted from January 2011 to June 2013 to the emergency room of the Hospital Universitario Central de Asturias were evaluated using a protocol including sociodemographic, psychiatric, and psychosocial assessment. Patients were randomly assigned to either a group receiving continuous case management including participation in a psychoeducation program (experimental group), or a control group receiving standard care. The primary objective is to examine whether or not the period of time until recurrent suicidal behaviour in the experimental group is significantly different from that of the control group. PSyMAC proposes low cost and easily adaptable interventions to the usual clinical setting that can help to compensate the shortcoming of specific action protocols and suicidal behaviour prevention programs in our country. The evaluation of PSyMAC results will determine their real effectivity as a case-magament program to reduce suicidal risk. Copyright © 2013 SEP y SEPB. Published by Elsevier España.

Background The role of dietary factors in the pathophysiology of acne vulgaris is highly controversial. Hence, the aim of this study was to determine the association between dietary factors and acne vulgaris among Malaysian young adults. Methods A case–control study was conducted among 44 acne vulgaris patients and 44 controls aged 18 to 30 years from October 2010 to January 2011. Comprehensive acne severity scale (CASS) was used to determine acne severity. A questionnaire comprising items enquiring into the respondent’s family history and dietary patterns was distributed. Subjects were asked to record their food intake on two weekdays and one day on a weekend in a three day food diary. Anthropometric measurements including body weight, height and body fat percentage were taken. Acne severity was assessed by a dermatologist. Results Cases had a significantly higher dietary glycemic load (175 ± 35) compared to controls (122 ± 28) (p < 0.001). The frequency of milk (p < 0.01) and ice-cream (p < 0.01) consumptions was significantly higher in cases compared to controls. Females in the case group had a higher daily energy intake compared to their counterparts in the control group, 1812 ± 331 and 1590 ± 148 kcal respectively (p < 0.05). No significant difference was found in other nutrient intakes, Body Mass Index, and body fat percentage between case and control groups (p > 0.05). Conclusions Glycemic load diet and frequencies of milk and ice cream intake were positively associated with acne vulgaris. PMID:22898209

Immune mechanism shares a common pathway both for systemic autoimmune diseases and periodontal diseases. Scientific exploration of literature revealed limited studies on the association between systemic autoimmune diseases and periodontal diseases in India. The aim of the study is to find whether the presence of systemic autoimmune diseases in an individual is a risk factor for the development of periodontal disease. This was a hospital-based case-control study. A sample of 253 patients with systemic autoimmune diseases, attending the Rheumatology Department of Government General Hospital, Chennai-3, and 262 patients without systemic autoimmune diseases, attending the outpatient department of the Tamil Nadu Government Dental College and Hospital, Chennai-3, constituted the case and control groups, respectively. Age, gender, and oral hygiene status matching was done. Oral hygiene status was assessed using oral hygiene index (OHI) and periodontal status was assessed using community periodontal index (CPI) and loss of attachment (LOA) index. Statistical analysis was done using SPSS version 15 (SPSS Inc, 2006, Chicago). Results showed 99.2% and 73.9% prevalence of gingivitis and periodontitis, respectively, in the case group as compared to 85.5% and 14.9%, respectively, in the control group. There is no linear relationship between OHI scores and prevalence of periodontitis (CPI and LOA scores) in the case group. Patients suffering from systemic autoimmune diseases showed more prevalence of periodontal diseases irrespective of oral hygiene scores. It is postulated that the presence of systemic autoimmune diseases may pose a risk for the development of periodontal diseases.

Personality traits have been proposed to affect the risk of sports concussion, but evidence is limited. Cloninger's Tridimensional Personality Questionnaire (TPQ) measures novelty seeking, harm avoidance (HA), and reward dependence traits. The aim of this study was to investigate the relationship between TPQ scores and concussion history in rugby union players. Cross-sectional study. Rugby players from high schools, senior amateur clubs, and professional teams provided a self-reported concussion history and completed the TPQ. Participants reporting no previous concussions formed the control group, while participants reporting concussion formed the case group. A one-way analysis of covariance, with age as a covariate, was used to examine the differences in TPQ scores between groups. Of the 309 participants, 54% reported a minimum of one concussion (junior: 47%; amateur: 52%; professional: 72%). HA scores were significantly higher in junior players without a history of concussion compared to cases (p=0.006). Specifically, the junior control group had higher "anticipatory worry" (p=0.009) and "fear of uncertainty" (p=0.008). In contrast, the professional control group had lower HA scores than cases (p=0.009), while the amateur cohort displayed no differences between control and case groups. This study identified a novel association between HA and concussion in rugby players, adding evidence to the role of personality in a multifactorial risk-model of concussion. The findings suggest that lower HA may lead to increased dangerous play in youth rugby, influencing concussion susceptibility. Contrasting associations in the professional cohort suggest further research is required to understand the role of personality in concussion. Copyright © 2017 Sports Medicine Australia.

Introduction: Secondary hyperparathyroidism (SHPT) is an insidious disease that develops early in the course of chronic kidney disease (CKD) and increases in severity as the glomerular filtration rate deteriorates. Recent studies have identified fibroblast growth factor-23 (FGF23) as a new protein with phosphaturic activity. It is mainly secreted by osteoblasts and is now considered the most important factor for regulation of phosphorus homeostasis. It is not yet proven if there is any direct relation between parathyroid hormone (PTH) and FGF23. The present study aims to evaluate the relation between serum FGF23, phosphorus, and PTH in end-stage renal disease in patients with SHPT on regular hemodialysis. Materials and Methods: Forty-six consecutive CKD adult patients (case group) and 20 healthy adults (control group) were included in the study. All patients had SHPT and were on regular hemodialysis. Both groups were subjected to full medical history, clinical examination and biochemical studies. Serum phosphorus, calcium, ferritin, hemoglobin level, blood urea, creatinine, PTH, and FGF23 were analyzed. Results: Levels of FGF23 were significantly higher in the case group in comparison with those in the control group, viz., 4-fold, and positively correlated with PTH. Phosphorus levels in the case group were significantly high in spite of the increasing levels of FGF23. Both PTH and FGF23 were positively correlated with phosphorus and negatively with hemoglobin levels. Conclusion: SHPT and FGF23 may have a partial role in the development of anemia in patients with CKD. FGF23 could be a central factor in the pathogenesis of SHPT. Its role in controlling hyperphosphatemia in CKD is vague. PMID:21731867

Gynecomastia, a benign enlargement of the breast glandular tissue in men. The aim of the study was to evaluate the phenotype of patients with gynecomastia, in particular antropometric assessment, breast ultrasound examination and hormonal testing, as well as to estimate possible causes of gynecomastia in studied population. Two hundred-twenty men were enrolled in the study: 126 patients with gynecomastia and 94 healthy volunteers as a control group. Detailed medical examination, breast ultrasound and hormonal assays for T, E2, LH, FSH, SHBG, S-DHEA, PRL and TSH were performed. Calculation of free testosterone concentration was done. The results of clinical and hormonal evaluation enabled to divide the cases into three groups: patients with idiopathic gynecomastia (58 subjects, 46%), with hypogonadism (34 subjects, 27%) and drug-induced or associated with other disorders gynecomastia (34 subjects, 27%). We found that men with gynecomastia, particularly associated with hypogonadism, had significantly higher BMI compared with control group. Ultrasound examination revealed the positive correlation between breast tissue volume and BMI, duration of gynecomastia and estradiol level, while negative correlation with testosterone level. We demonstrated significant differences in LH, T, SHBG, fT and S-DHEA levels between cases and controls. There were no differences in PRL, FSH and TSH levels among groups. Significant elevation of SHBG concentration in all groups of patients, including idiopathic gynecomastia cases, compared with controls, was remarkable. Clinical evaluation and hormonal profile can help to classify patient with gynecomastia into one of three groups: idiopathic gynecomastia, associated with hypogonadism, and drug-induced or associated with other diseases. Idiopathic gynecomastia - of unknown etiology is diagnosed in almost half of all cases (46%). We showed that apart from well known hormonal disturbances leading to gynecomastia, like hypogonadism or hyperestrogenism, also subtle hormonal alterations, such as sex hormone binding globuline (SHBG) level elevation may contribute to breast enlargement.

The aim of the present study was to evaluate the association of fatty acids and lipids metabolism in placenta with early spontaneous pregnancy loss (ESPL) in Chinese women. Seventy women with ESPL and 29 healthy pregnant women who asked for legal induced abortion were included in the case and control groups, respectively. The gestational age of the subject foetuses in both the case and control groups ranged from 4 to 10 weeks. The total fatty acids composition in the decidual and villous tissues was detected by gas-liquid chromatography using a standard method. Metabonomics analysis of the decidual and villous tissues was conducted by ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-QTOFMS). The total C18:3n-3 in the decidual and villous tissues, total n-3 polyunsaturated fatty acid (n-3 PUFA) in the decidual tissue, and total C18:2n-6 in the villous tissue were all significantly lower in the case group than in the control group. The ratio of C20:4n-6/C20:5n-3 in villous tissue was significantly higher, but prostaglandin I 2 as well as hydroxyeicosapentaenoic acid, leukotriene B 5 and thromboxane B 3 in the villous tissue were significantly lower in the case group than in the control group. In addition, the low content of lysophosphatide in the decidual and villous tissues and the low content of diacylglycerol in the villous tissue were also associated with the occurance of ESPL. In conclusion, the lack of essential fatty acids, high ratio of C20:4n-6/C20:5n-3, abnormal eicosanoids metabolism and low content of lysophosphatide and diacylglycerol in the placenta were all potential risk factors for ESPL in Chinese.

Amyloid PET (aPET) imaging could improve patient outcomes in clinical practice, but the extent of impact needs quantification. To provide an aggregated quantitative analysis of the value added by aPET in cognitively impaired subjects. Systematic literature searches were performed in Embase and Medline until January 2017. 1,531 cases over 12 studies were included (1,142 cases over seven studies in the primary analysis where aPET was the key biomarker; the remaining cases included as defined groups in the secondary analysis). Data was abstracted by consensus among two observers and assessed for bias. Clinical utility was measured by diagnostic change, diagnostic confidence, and patient management before and after aPET. Three groups were further analyzed: control patients for whom feedback of aPET scan results was delayed; aPET Appropriate Use Criteria (AUC+) cases; and patients undergoing additional FDG/CSF testing. For 1,142 cases with only aPET, 31.3% of diagnoses were revised, whereas 3.2% of diagnoses changed in the delayed aPET control group (p < 0.0001). Increased diagnostic confidence following aPET was found for 62.1% of 870 patients. Management changes with aPET were found in 72.2% of 740 cases and in 55.5% of 299 cases in the control group (p < 0.0001). The diagnostic value of aPET in AUC+ patients or when FDG/CSF were additionally available did not substantially differ from the value of aPET alone in the wider population. Amyloid PET contributed to diagnostic revision in almost a third of cases and demonstrated value in increasing diagnostic confidence and refining management plans.

Intensive cognitive therapy for post-traumatic stress disorder (PTSD) has been shown to be as effective as weekly treatment in controlled trials. In this study, outcome data comparing standard and intensive treatments delivered in routine clinical practice were analysed. A consecutive case series of intensive treatment cases were compared to matched control cases who had completed weekly treatment. Both groups showed significant improvements on PTSD and depression measures. The intensive group showed larger PTSD symptomatic improvement. There were differences between the groups in age and time since trauma, suggesting selection biases in who is offered, and/or who chooses intensive treatment. For some individuals, an intensive format may be more effective than weekly treatment. © 2017 The British Psychological Society.

Background The Study to Explore Early Development (SEED) is designed to enhance knowledge of autism spectrum disorder characteristics and etiologies. Objective This paper describes the demographic profile of enrolled families and examines sociodemographic differences between children with autism spectrum disorder and children with other developmental problems or who are typically developing. Methods This multi-site case-control study used health, education, and birth certificate records to identify and enroll children aged 2–5 years into one of three groups: 1) cases (children with autism spectrum disorder), 2) developmental delay or disorder controls, or 3) general population controls. Study group classification was based on sampling source, prior diagnoses, and study screening tests and developmental evaluations. The child's primary caregiver provided demographic characteristics through a telephone (or occasionally face-to-face) interview. Groups were compared using ANOVA, chi-squared test, or multinomial logistic regression as appropriate. Results Of 2768 study children, sizeable proportions were born to mothers of non-White race (31.7%), Hispanic ethnicity (11.4%), and foreign birth (17.6%); 33.0% of households had incomes below the US median. The autism spectrum disorder and population control groups differed significantly on nearly all sociodemographic parameters. In contrast, the autism spectrum disorder and developmental delay or disorder groups had generally similar sociodemographic characteristics. Conclusions SEED enrolled a sociodemographically diverse sample, which will allow further, in-depth exploration of sociodemographic differences between study groups and provide novel opportunities to explore sociodemographic influences on etiologic risk factor associations with autism spectrum disorder and phenotypic subtypes.

The evolution of autistic disorders in children depends on many factors, like concomitance of the other diseases, which can escalate the autistic symptoms. One of those groups are allergic diseases, which have one of the highest prevalence rates in children. The aim of this analysis was to determine the frequency of asthma and allergy in children with autism in comparison to controls and the risk factors of allergic diseases and asthma in both groups. Study population included 96 cases diagnosed with childhood or atypical autism and 192 controls matched individually by year of birth, gender and physician's practice. The analysis was performed in each group separately giving possibility to compare the results between study groups. The frequency of asthma and allergic diseases in both groups has not revealed any statistically significant differences. Children with autism have been affected by asthma in 5,2% and by allergy in 25,0%, controls in 4,7% and 21,9% respectively. All cases of asthma was diagnosed in boys, commonly allergy was also more frequent in boys than girls in both studied groups. However those differences was statistically insignificant. The father's allergy and asthma was revealed as a risk factor of allergy in children with autism. In controls additionally allergy or asthma diagnosed in mother or grandparent increased risk of allergy in children. Children with autism were affected by asthma and allergy with similar frequency like children without autistic disorders. Allergy in father was the risk factor of allergic diseases in children with autism.

The aim of the present study was to explore if (a) recurrent low back pain (LBP) has different symptomatologies in cases from occupations with predominantly sitting postures compared to cases from occupations involving dynamic postures and frequent lifting and (b) if in the two occupational groups, different factors were associated with the presence of recurrent LBP. Hundred and eleven female subjects aged between 45 and 62 years with a long-standing occupation either in administrative or nursing professions, with and without recurrent LBP were examined. An extensive evaluation of six areas of interest (pain and disability, clinical examination, functional tests, MR examination, physical and psychosocial workplace factors) was performed. The variables from the six areas of interest were analyzed for their potential to discriminate between the four groups of subjects (administrative worker and nurses with and without recurrent LBP) by canonical discriminant analysis. As expected, the self-evaluation of physical and psychosocial workplace factors showed significant differences between the two occupational groups, which holds true for cases as well as for controls (P < 0.01). The functional tests revealed a tendency for rather good capacity in nurses with LBP and a decreased capacity in administrative personnel with LBP (P = 0.049). Neither self completed pain and disability questionnaires nor clinical examination or MR imaging revealed any significant difference between LBP cases from sedentary and non-sedentary occupations. When comparing LBP cases and controls within the two occupational groups, the functional tests revealed significant differences (P = 0.0001) yet only in administrative personnel. The clinical examination on the other hand only discriminated between LBP cases and controls in the nurses group (P < 0.0001). Neither MRI imaging nor self reported physical and psychosocial workplace factors discriminated between LBP cases and controls from both occupational groups. Although we used a battery of tests that have broad application in clinical and epidemiological studies of LBP, a clear difference in the pattern of symptoms between LBP cases from nursing and hospital administration personnel could not be ascertained. We conclude that there is no evidence for different mechanisms leading to non-specific, recurrent LBP in the two occupations, and thus no generalizable recommendations for the prevention and therapy of non-specific LBP in the two professions can be given.

To evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions. One hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up. According to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05). The weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

Summary A genome-wide association study was undertaken to identify maternal single nucleotide polymorphisms (SNPs) and copy-number variants (CNVs) associated with preeclampsia. Case-control analysis was performed on 1070 Afro-Caribbean (n=21 cases and 1049 controls) and 723 Hispanic (n=62 cases and 661 controls) mothers and 1257 mothers of European ancestry (n=50 cases and 1207 controls) from the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study. European ancestry subjects were genotyped on Illumina Human610-Quad and Afro-Caribbean and Hispanic subjects were genotyped on Illumina Human1M-Duo BeadChip microarrays. Genome-wide SNP data were analyzed using PLINK. CNVs were called using three detection algorithms (GNOSIS, PennCNV, and QuantiSNP), merged using CNVision, and then screened using stringent criteria. SNP and CNV findings were compared to those of the Study of Pregnancy Hypertension in Iowa (SOPHIA), an independent preeclampsia case-control dataset of Caucasian mothers (n=177 cases and 116 controls). A list of top SNPs were identified for each of the HAPO ethnic groups, but none reached Bonferroni-corrected significance. Novel candidate CNVs showing enrichment among preeclampsia cases were also identified in each of the three ethnic groups. Several variants were suggestively replicated in SOPHIA. The discovered SNPs and copy-number variable regions present interesting candidate genetic variants for preeclampsia that warrant further replication and investigation. PMID:23551011

Obesity is a worldwide health problem which is associated with a lot of complications. One of these comorbidities is the metabolic syndrome that is in correlation with abdominal fat thickness and waist circumference. Various methods were used to reduce abdominal fat thickness such as liposuction. A noninvasive method is the topical agent. In this study, we investigated the effectiveness of Arnebia euchroma (AE) ointment on the abdominal fat thickness. This study was a double-blind clinical trial which was done at the endocrinology clinic in Khorshid Hospital, Isfahan, Iran, in 2014. After explaining the procedure and obtaining informed consent, the candidates were randomly divided into the case and control groups. The participants of the case and control groups applied AE ointment or placebo for 6 weeks on their abdominal area. Body mass index, waist and buttock circumference, and abdominal fat thickness were measured in both case and control groups at their first visit and then at the next 2, 4, and 6 weeks. We used t -test for comparing parametric variables between groups, paired t -test for changes from baseline to final, and repeated measure ANOVA for changes at different steps. Sixty female candidates participated in this study (thirty in each group). Ten patients left the study and fifty participants finished the trial. At the end of the study, participants had a significant weight loss (2.96 ± 1.6 kg, P < 0.001) that was slightly more in the case group (3.15 ± 1.5 kg vs. 2.75 ± 1.7, P = 0.375). Abdominal circumference also decreased significantly in the participants (11.3 ± 6.7 cm, P < 0.001), but the changes were more significant in the case group (13.9 vs. 6.5 cm, P = 0.004). Similarly, abdominal fat thickness decreased significantly in the participants (2.3 ± 1.1 cm, P < 0.001), although changes were not significantly different between two groups (2.53 vs. 2.04 cm, P = 0.139). Topical AE ointment can reduce the abdominal fat thickness as well as the waist circumference without causing any side effect.

Information on serum albumin and trace elements among children suffering from Sickle Cell Anemia (SCA) was poorly documented in Africa. The aim of this study was to describe and to compare different values of trace elements with published reports from other parts of the world. We carried out a case-control study. Seventy-six steady state children suffering from SCA (Hb-SS). One hundred and fifty-two children were recruited with 76 (cases, Hb-SS) and 76 (control, Hb-AA) to compare the data. The mean age was 10.0 years (SD=5.4) in SCA children and 9.2 years (SD=4.7) in the control group. The mean level of zinc and magnesium were slightly lower in the Hb-SS group than in the Hb-AA group (P<.001). The first literature about trace elements in SCA is briefly reported in Central Africa. In our midst, zinc, magnesium, and selenium deficiencies underline the need for their systematic among all children with SCA to identify patients with these deficiencies and provide early management. © 2017 Wiley Periodicals, Inc.

The objective of this study was to compare results between the magnetic navigation system (MNS) and conventional catheter ablation of cavo-tricuspid isthmus (CTI)-dependent right atrial flutter (AFL) in a case control study. A remote MNS has been used for ablation of various arrhythmias including CTI-dependent AFL but comparative results between MNS and conventional ablation are not available. Between May and September 2007, a total of 51 consecutive patients (45 men, mean age 65.4 +/- 9.4 years) had undergone catheter ablation for CTI-dependent AFL. The catheter ablation (70 degrees C, 70 W, 90 s) was performed with either an 8-mm-tip magnetic catheter using MNS (case group, n = 26, 23 men, mean age 64.6 +/- 9.6 y) or a conventional 8-mm catheter (case group, n = 25, 22 men, mean age 65.4 +/- 9.1 y). Acute procedural success was defined as complete bidirectional isthmus block and success at six months was defined as absence of AFL during the six months follow-up. With respect to baseline characteristics there were no differences between the two groups. The procedure time in MNS and conventional group was [median (range)] 53 (30-130) min and 45 (30-100) min, respectively (P = 0.12). Acute success was achieved by MNS and conventional ablation in 25/26 (96.2%) and 25/25 (100%) of patients, respectively (P = 0.53). During the six months of follow-up 4 patients, 2 in each group, experienced recurrence (P = 0.90). No major complication occurred during the procedure. Charring on the catheter tip occurred in 5 patients (19.2%) in MNS and none of the patients in the control group (P <0.05). This case-control study demonstrated the acute and mid-term efficacy and safety of catheter ablation by MNS for CTI-dependent AFL, similar to rates achieved by conventional radiofrequency catheter ablation.

In a nonrandomized clinical trial, 101 undergraduates enrolled in the "Adult Patients 1" course were assigned to the traditional lecture and discussion (n = 66) or lecture and discussion plus case-based learning (n = 35) arm of the study; 59 CPE nurses constituted a comparison group to assess the effects of previous clinical experience on learning outcomes. Scores on an objective structured clinical examination (OSCE), using a human patient simulator and cases validated by the National League for Nursing, were compared for the undergraduate control and intervention groups, and for CPE nurses (Student's t test). Controls scored lower than the intervention group on patient assessment (6.3 ± 2.3 vs 7.5 ± 1.4, p = .04, mean difference, -1.2 [95% confidence interval (CI) -2.4 to -0.03]) but the intervention group did not differ from CPE nurses (7.5 ± 1.4 vs 8.8 ± 1.5, p = .06, mean difference, -1.3 [95% CI -2.6 to 0.04]). The CPE nurses committed more "rules-based errors" than did undergraduates, specifically patient identifications (77.2% vs 55%, p = .7) and checking allergies before administering medication (68.2% vs 60%, p = .1). The intervention group developed better patient assessment skills than the control group. Case-based learning helps to standardize the process, which can contribute to quality and consistency in practice: It is essential to correctly identify a problem in order to treat it. Clinical experience of CPE nurses was not associated with better adherence to safety protocols. Case-based learning improves the patient assessment skills of undergraduate nursing students, thereby preparing them for clinical practice. © 2014 Sigma Theta Tau International.

Acute pulmonary emphysema (APE) has been described in cases of mechanical asphyxia such as ligature or manual strangulation but not in cases of hanging. In this study, we wanted to verify by morphometric digital analysis of lung tissue whether APE occurs in death by hanging.We investigated 16 cases of hanging (eight complete, eight incomplete), 10 cases of freshwater drowning (positive control group), and 10 cases of acute external bleeding (negative control group). Tissue sections were obtained from each pulmonary lobe. For each slide, five fields were randomly selected. The area of every alveolar space was measured by image analysis software. The mean alveolar area (MAA) was calculated for each group.In incomplete hanging, MAA was significantly higher than that observed in complete hanging and similar to the one observed in freshwater drowning.APE in cases of incomplete hanging can be considered as a sign of vitality. The high number of conditions that can cause alveolar distension (that were excluded in this study) limits the applicability of this vital sign in the routine forensic practice.

During the 2014-2015 influenza season in the United States, 256 cases of influenza-associated parotitis were reported from 27 states. We conducted a case-control study and laboratory investigation to further describe this rare clinical manifestation of influenza. During February 2015-April 2015, we interviewed 50 cases (with parotitis) and 124 ill controls (without parotitis) with laboratory-confirmed influenza; participants resided in 11 states and were matched by age, state, hospital admission status, and specimen collection date. Influenza viruses were characterized using real-time polymerase chain reaction and next-generation sequencing. We compared cases and controls using conditional logistic regression. Specimens from additional reported cases were also analyzed. Cases, 73% of whom were aged <20 years, experienced painful (86%), unilateral (68%) parotitis a median of 4 (range, 0-16) days after onset of systemic or respiratory symptoms. Cases were more likely than controls to be male (76% vs 51%; P = .005). We detected influenza A(H3N2) viruses, genetic group 3C.2a, in 100% (32/32) of case and 92% (105/108) of control specimens sequenced (P = .22). Influenza B and A(H3N2) 3C.3 and 3C.3b genetic group virus infections were detected in specimens from additional cases. Influenza-associated parotitis, as reported here and in prior sporadic case reports, seems to occur primarily with influenza A(H3N2) virus infection. Because of the different clinical and infection control considerations for mumps and influenza virus infections, we recommend clinicians consider influenza in the differential diagnoses among patients with acute parotitis during the influenza season.

This randomized controlled study compared two types of case management for skilled nursing level patients living at home: the centralized individual model and the neighborhood team model. The team model differed from the individual model in that team case managers performed client assessments, care planning, some direct services, and reassessments; they also had much smaller caseloads and were assigned a specific catchment area. While patients in both groups incurred very high estimated health services costs, the average annual cost during 1983-85 for team cases was 13.6 percent less than that of individual model cases. While the team cases were 18.3 percent less expensive among "old" patients (patients who entered the study from the existing ACCESS caseload), they were only 2.7 percent less costly among "new" cases. The lower costs were due to reductions in hospital days and home care. Team cases averaged 26 percent fewer hospital days per year and 17 percent fewer home health aide hours. Nursing home use was 48 percent higher for the team group than for the individual model group. Mortality was almost exactly the same for both groups during the first year (about 30 percent), but was lower for team patients during the second year (11 percent as compared to 16 percent). Probable mechanisms for the observed results are discussed.

To determine temporal patterns of vital sign and Cardiac Arrest Risk Triage score changes over the 48-hour period preceding cardiac arrest in an ICU setting. Vital sign instability usually occurs prior to cardiac arrest. However, few studies have been conducted on the temporal patterns of individual vital signs preceding cardiac arrest. A retrospective case-control study. The study subjects were 140 ICU patients (1 June 2011-31 December 2012): 46 died of cardiac arrest (case group), 45 died of other illnesses (control I group) and 49 were discharged after recovering (control II group). Initial detectable changes in blood pressure appeared 18-20 hours and became dramatic at 5-10 hours before cardiac arrest. Noticeable changes in heart rates began at 4 hours and became more prominent at 2 hours pre-arrest. No apparent patterns in respiratory rate changes were observed. Body temperatures usually indicated a hypothermic state pre-arrest. Cardiac Arrest Risk Triage scores were 16-18 at 48 hours pre-arrest and then continuously increased to 20. Only mean values of systolic blood pressures were significantly different between the three study groups. Mean diastolic blood pressures, heart rates, respiratory rates and Cardiac Arrest Risk Triage scores differed between the case and control II groups and between the control I and II groups. The study demonstrates vital sign instability preceded cardiac arrest and that the temporal patterns of changes in individual vital signs and Cardiac Arrest Risk Triage scores differed between groups. The findings of this study may aid the development of management strategies for cardiac arrest. © 2016 John Wiley & Sons Ltd.

Idiopathic choroidal neovascularization (ICNV) affects young patients and thus may have a significant impact on vision and life quality over a patient's lifespan. This study was designed to compare the visual outcome and retinal pigment epithelium (RPE) damage after photodynamic therapy (PDT) with small laser spot and PDT with standard laser spot for idiopathic choroidal neovascularization (ICNV). This was a randomized controlled study. Fifty-two patients with ICNV were enrolled and randomly divided into a study group (small laser spot PDT, n = 27) and a control group (standard laser spot PDT, n = 25). Best corrected visual acuity (BCVA), optic coherence tomography (OCT) and fluorescein angiography (FA) findings were the main measurements. The patients were followed up 1 week, 1, 3, 6, 9 months and 1 year after PDT. BCVA improvement was statistically significantly higher in the study group than the control group at 6-month ((25.53 ± 15.01) letters vs. (14.71 ± 11.66) letters, P = 0.025) and 9-month follow-ups ((27.53 ± 17.78) letters vs. (15.59 ± 12.21) letters, P = 0.039). At 3- and 6-month follow-ups, the quadrants of RPE damage between the two groups varied significantly (P < 0.001 and P = 0.023, respectively). In each follow-up, the number of cases with decreased or unchanged leakage of choroidal neovascularization by FA and reduced subretinal fluid by OCT did not vary significantly between the two groups. Ten cases (37.0%) in the study group and eight cases (32.0%) in the control group suffered from recurrent CNV (P = 0.703). Better visual improvements, less RPE damage, a similar recurrent rate of CNV and change of subretinal fluid were observed in the small laser spot PDT group than in the standard laser spot PDT group for ICNV.

The aim of this study was to compare the obstetric outcomes after successful external cephalic version (cases) with a group of pregnant women with a spontaneous cephalic fetal position at delivery (controls). Retrospective review of the cohort of study was performed at the University Hospital of Getafe (Madrid, Spain) between January 2012 and January 2013. 1516 patients (48 cases; 1468 controls). We compared the type of delivery in pregnant women after ECV performed successfully (cases) with spontaneous cephalic presentations (controls). Pregnancies with vaginal delivery contraindicated, elective cesarean section (CS) justified by maternal disease, multiple pregnancies, or pregnancies below 37 weeks were excluded. Maternal age, BMI, parity, gestational age at delivery, and onset of labor (spontaneous or induced) were controlled. Prevalence of CS and operative delivery in both groups. Women who underwent a successful ECV had a significantly higher CS rate compared with the women of the control group (12/48 [25%] vs. 202/1468 [13.76%]; P=0.028). There was no difference in the rate of operative delivery (6/48 [12.5%] vs. 177/1468 [12.05%] P=0.92). Deliveries following a successful ECV are associated with an increased CS rate compared with deliveries of fetuses with spontaneous cephalic presentations.

This study is the result of two Portuguese case-control studies that examined the replication of retrospective correlates and preceding life events in anorexia nervosa (AN) and bulimia nervosa (BN) development. This study aims to identify retrospective correlates that distinguish AN and BN METHOD: A case-control design was used to compare a group of women who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for AN (N = 98) and BN (N = 79) with healthy controls (N = 86) and with other psychiatric disorders (N = 68). Each control group was matched with AN patients regarding age and parental social categories. Risk factors were assessed by interviewing each person with the Oxford Risk Factor Interview. Compared to AN, women with BN reported significantly higher rates of paternal high expectations, excessive family importance placed on fitness/keeping in shape, and negative consequences due to adolescent overweight and adolescent objective overweight. Overweight during adolescence emerged as the most relevant retrospective correlate in the distinction between BN and AN participants. Family expectations and the importance placed on keeping in shape were also significant retrospective correlates in the BN group.

Background Recurrent vulvovaginal candidiasis (RVVC) is a common cause of morbidity affecting millions of women worldwide. Patients with RVVC are thought to have an underlying immunologic defect. This study has been established to evaluate cell-mediated immunity defect in response to candida antigen in RVVC cases. Materials and Methods Our cross-sectional study was performed in 3 groups of RVVC patients (cases), healthy individuals (control I) and known cases of chronic mucocutaneous candidiasis (CMC) (control II). Patients who met the inclusion criteria of RVVC were selected consecutively and were allocated in the case group. Peripheral blood mononuclear cells were isolated and labeled with CFSE and proliferation rate was measured in exposure to candida antigen via flow cytometry. Results T lymphocyte proliferation in response to candida was significantly lower in RVVC cases (n=24) and CMC patients (n=7) compared to healthy individuals (n=20, P<0.001), but no statistically significant difference was seen between cases and control II group (P>0.05). Family history of primary immunodeficiency diseases (PID) differed significantly among groups (P=0.01), RVVC patients has family history of PID more than control I (29.2 vs. 0%, P=0.008) but not statistically different from CMC patients (29.2 vs. 42.9%, P>0.05). Prevalence of atopy was greater in RVVC cases compared to healthy individuals (41.3 vs. 15%, P=0.054). Lymphoproliferative activity and vaginal symptoms were significantly different among RVVC cases with and without allergy (P=0.01, P=0.02). Conclusion Our findings revealed that T cells do not actively proliferate in response to Candida antigen in some RVVC cases. So it is concluded that patients with cell-mediated immunity defect are more susceptible to recurrent fungal infections of vulva and vagina. Nonetheless, some other cases of RVVC showed normal function of T cells. Further evaluations showed that these patients suffer from atopy. It is hypothesized that higher frequency of VVC in patients with history of atopy might be due to allergic response in mucocutaneous membranes rather than a functional impairment in immune system components.

To study the clinical efficacy of supplementary treatment of tukang Capsules to the elder patients with fracture of the distal radius. A total of 108 elder patients with fracture of the distal radius diagnosed by X-ray,who visited orthopedics department of Pu' ai Hospital in January 2012 - December 2013, were randomly divided into observation group and control group. Cases in both groups received the operation of internal fixation by T-type plate. Cases in control group received oral Calcium Carbonate Tablets, and cases in observation group received Gukang Capsules besides Calcium Carbonate Tablets. Treatment duration was four weeks. The painful and swelling degree of wrist joints, levels of type I propeptide carboxy-terminal procollagen (P I CP) and bone glaprotein(BGP) in serum were compared. Hospitalization and fracture healing time, as well as recovery condition of wrist joints in the sixth month after operation were compared. The VAS of both groups was not significantly different before operation and in the 28th day after operation(P >0. 05), but the VAS in observation group was significantly lower than that in control group in the 3rd,5th, 7th, 14th and 21th day after operation(P <0. 01). The swelling scale of both groups was not significantly different before operation and in the 28th day after operation(P >0. 05), but the swelling scale in observation group was significantly lower than that in control group in the 3rd, 5th, 7th, 14th and 21th day after operation(P <0. 01). The levels of P I CP and BGP in serum of both groups were not significantly different before operation(P >0. 05), but the levels of P I CP and BGP in serum of observation groups were significantly higher than that in control group one and two months after operation (P <0. 01). Hospitalization and fracture healing time in observation group was significantly shortened compared with control group (P <0. 05). The effective ratio in observation group was 79. 63%, significantly higher than that in control group (P <0. 05). Gukang Capsules supplementary to internal fixation by T-type plate has favorable efficacy to fracture of the distal radius, which can reduce pain and swelling, increase levels of P I CP and BGP in serum, as well as promote the heal of fracture and recovery of wrist joints function.

To assess the efficacy and safety of reduced osmolarity oral rehydration salts (ROORS) in treatment of mild to moderate dehydration caused by acute diarrhea in children. A multicenter, randomized, double-blind, positive drug controlled clinical trial was conducted in 125 cases aged 1 to 17 years. These children with acute diarrhea and signs of dehydration were randomly assigned to receive either ROORS (trial group, n = 62) or oral rehydration salts II (ORS II) (control group, n = 63). The volume of intravenous infusion were recorded. The improvements of systemic symtoms and signs, diarrhea, dehydration and total scores were compared between the two groups. The adverse events and changes of electrolyte and other laboratory tests during treatment were also observed and analyzed. The overall effective rates in trial group and control group were 96.8% and 96.8%, respectively. The recovery of systemic symptoms, dehydration signs and diarrhea occurred in 96%, 97% and 78% patients in trial groups, and 96%, 98% and 85% patients in control group. The scores of symptoms and signs in both groups decreased significantly after treatment. All the above parameters and the number of cases who needed intravenous infusion (41 vs. 39) were not statistically different between two groups. However, the average volume of intravenously infused fluids in trial group was (450.98 +/- 183.07) ml, 24.5% less than that in the control group (597.30 +/- 343.37) ml (P < 0.05). The mean serum Na(+) concentration elevated from (137.48 +/- 4.55) mmol/L to (139.52 +/- 3.25) mmol/L (P < 0.01) in control group after treatment, but the change was not statistically significant in trail group. Serum K(+), Cl(-), HCO(3)(-) and other laboratory result did not change significantly after treatment. The total scores in both groups decreased obviously after treatment, but no significant difference was demonstrated between two groups (P > 0.05). A case in trial group had mild abdominal distention and recovered spontaneously. ROORS was shown to be effective and safe in the treatment of mild and moderate dehydration induced by acute diarrhea. Compared to ORS II, ROORS could decrease the intravenous supplement of fluid and lower the risk of hypernatremia.

To investigate the effects of mRNA transcriptional and protein expressions of protein kinase Cδ (PKCδ) on the development of arsenic liver injury caused by coal-burning. Population study:133 arsenic exposures were selected as arsenic exposure groups including the ward non-patient group (25 cases) , no obvious hepatopathy group (38 cases) , mild (43 cases) and moderate to severe hepatopathy group (27 cases) from the area with endemic arsenism in Guizhou province. Another 34 healthy residents were selected as the control group in non-arsenic pollution village. The urine and peripheral blood were collected from the subjects. The arsenic contents in urine and mRNA expressions of PKCδ in peripheral blood were detected. Animal experiment study:thirty wistar rats were randomly by random number table divided into control group, drinking water arsenic poisoning group and coal-burning arsenic poisoning group (i.e., low, medium and high arsenic contaminated grain group) by random number table method, including 6 rats in each group. The control group was fed normally for 3 months, drinking water arsenic poisoning group and coal-burning arsenic poisoning groups were fed respectively with 10 mg/kg As2O3 solution and different concentrations (25, 50 and 100 mg/kg) of arsenic-containing feed which was persisted 3 months. The arsenic contents in urine, mRNA expression levels of PKCδ in peripheral blood and liver tissue and the protein expression levels of phosphorylated protein kinase Cδ(pPKCδ) in liver tissue were detected. The median(quartile) of arsenic contents in urine were 25.58 (18.62-40.73), 56.66 (38.93-76.77), 64.90 (39.55- 98.37) and 75.47 (41.30-109.70) µg/g Cr respectively for the non-patient group, no obvious hepatopathy group, mild and moderate to severe hepatopathy group. The levels were higher than that in the control group (23.34 (17.84-37.45) µg/g Cr) (P < 0.05), except for the ward non-patient group. The arsenic contents in rat urine were 2223.61 (472.98-3976.73), 701.16 (194.01-1300.27), 1060.94 (246.33-2585.47) and 3101.11 (1919.97-5407.07) µg/g Cr, respectively for the drinking water arsenic poisoning group, the low, medium and high dosage arsenic grain contamination groups, all higher than that in the control group (94.32 (22.65-195.25) µg/g Cr) (P < 0.05) . The protein expressions of pPKCδ in liver tissue were 324.83 ± 25.06, 278.50 ± 30.57, 308.83 ± 34.67 and 326.33 ± 35.09, which were significantly higher than that in the control group (240.17 ± 28.07) (P < 0.05) . The protein expression levels of pPKCδ in liver cell membrane were 0.49 ± 0.06,0.33 ± 0.05,0.37 ± 0.06 and 0.50 ± 0.08, which were significantly higher than that in the control group (0.28 ± 0.04) (P < 0.05) . The protein expression levels of pPKCδ in liver cell cytoplasm were 0.38 ± 0.06,0.31 ± 0.05, 0.35 ± 0.05 and 0.36 ± 0.05, which were significantly higher than that in the control group (0.24 ± 0.05) (P < 0.05). The arsenic may regulate protein expressions of pPKCδ and induce its membrane translocation, and cause the development of arsenic liver injury caused by coal-burning.

Acromegaly is a chronic disease resulting from pathological oversecretion of growth hormone and subsequently insulin growth factor-1. Several complications of the disease have been reported, including cardiovascular diseases, respiratory disorders but also increased risk of benign and malignant neoplasms. The aim of the study was to evaluate the risk of malignant neoplasms in the patients with acromegaly in comparison with the control group. Medical documentation of acromegalic patients treated in one medical center between 2005 and 2016 has been analyzed. Results were compared with sex- and age-matched group of subjects with prolactinomas and hormonally inactive pituitary lesions hospitalized in the same department. Two hundred patients with acromegaly were included. Control group was composed of 145 patients. Any malignant neoplasm in anamnesis was present in 27 (13.5 %) patients with acromegaly and six (4.1 %) subjects from control group (p = 0.003). Thyroid cancer was present in 14 (7.0 %) patients with acromegaly and two (1.4 %) in control group (p = 0.02). Breast cancer was present in seven women (5.4 % of women) in acromegaly group but none of subjects in control group (p = 0.02). Colon cancer-4 (2.0 %) patients in acromegaly group and 0 in control group (p = 0.14). Malignant neoplasms are significantly more common in patients with acromegaly. Particularly, risk of thyroid cancer was increased over fivefold. Systematic screening for neoplastic diseases should be important part of follow-up in these patients. Further case-control studies are strongly indicated to evaluate which neoplasms are more common in acromegalic patients and what is the exact risk of malignancy.

To determine risk factors associated with the occurrence of sporadic cases of Salmonella enteritidis infections among children in France, we conducted a matched case-control study. Cases were identified between 1 March and 30 September 1995. One hundred and five pairs of cases and controls matched for age and place of residence were interviewed. In the 1-5 years age group, illness was associated with the consumption of raw eggs or undercooked egg-containing foods (OR 2.4, 95% CI 1.2-4.8). Storing eggs more than 2 weeks after purchase was associated with Salmonella enteritidis infection (OR 3.8, 95% CI 1.4-10.2), particularly during the summer period (OR 6.0, 95% CI 1.3-26.8). Cases were more likely to report a case of diarrhoea in the household 10-3 days before the onset of symptoms, particularly in the age group < or = 1 year (P = 0.01). This study confirms the link between eggs and the occurrence of sporadic cases of Salmonella enteritidis among children, highlights the potential role of prolonged egg storage and underlines the role of person-to-person transmission in infants.

Introduction and objective Acute injury transiently lowers local mechanical pain thresholds at a limb. To elucidate the impact of painless (diabetic) neuropathy on this post-traumatic hyperalgesia, pressure pain perception thresholds after a skeletal foot trauma were studied in consecutive persons without and with neuropathy (i.e. history of foot ulcer or Charcot arthropathy). Design and methods A case–control study was done on 25 unselected clinical routine patients with acute unilateral foot trauma (cases: elective bone surgery; controls: sprain, toe fracture). Cases were 12 patients (11 diabetic subjects) with severe painless neuropathy and chronic foot pathology. Controls were 13 non-neuropathic persons. Over 1 week after the trauma, cutaneous pressure pain perception threshold (CPPPT) and deep pressure pain perception threshold (DPPPT) were measured repeatedly, adjacent to the injury and at the opposite foot (pinprick stimulators, Algometer II®). Results In the control group, post-traumatic DPPPT (but not CPPPT) at the injured foot was reduced by about 15–25%. In the case group, pre- and post-operative CPPPT and DPPPT were supranormal. Although DPPPT fell post-operatively by about 15–20%, it remained always higher than the post-traumatic DPPPT in the control group: over musculus abductor hallucis 615 kPa (kilopascal) versus 422 kPa, and over metatarsophalangeal joint 518 kPa versus 375 kPa (medians; case vs. control group); CPPPT did not decrease post-operatively. Conclusion Physiological nociception and post-traumatic hyperalgesia to pressure are diminished at the foot with severe painless (diabetic) neuropathy. A degree of post-traumatic hypersensitivity required to ‘pull away’ from any one, even innocuous, mechanical impact in order to avoid additional damage is, therefore, lacking. PMID:25397867

To study the effect of Acanthopanax senticosus injection (ASI) on the activities of human tumor necrosis factor (TNF) and natural killer cell (NKC) in the patients with lung cancer and the underlying mechanism. 73 cases with lung cancer were randomly divided into two groups, namely, the treatment group (n = 39) and observation group (n = 34); 61 cases with or without other diseases were respectively divided into control A (n = 30) and B (n = 31) groups. The patients in treatment group were injected with ASI for 21 days. The activities of human TNF and NKC and the levels of IgG, IgA and IgM were detected respectively. After injection with ASI the activity of TNF-alpha in treatment group was comparable with that in the two control groups and was significant lower that that in observation group. The activity of TNF-beta and the levels of IgA, IgG and IgM were significantly higher than those in observation group and two control groups (P < 0.01). The activity of NKC was also remarkably higher than observation and two control groups. ASI can regulate the cellular immunity and factor, indicating that ASI can be used as an assistant drug to regulate the function of cellular immunity in the patients with lung cancer.

To observe the impacts of acupuncture of reinforcing kidney and activating spleen on the excretion of urinary fluoride and pain of the patients with drinking-water type fluorosis. The randomized controlled and single-blind trial was adopted. Seventy-two cases were randomized into an observation group and a control group, 36 cases in each one. In the observation group, acupuncture was applied at Pishu (BL 20), Shenshu (BL 23), Guanyuan (CV 4), Zusanli (ST 36), etc. , three treatments a week. In the control group, the Calcium Carbonate D3 tablets were prescribed for oral administration, 600 mg each time, twice a day. The duration of treatment was 2 months. The changes of the content of urinary fluoride and pain score (by VAS) before and after treatment between two groups were compared. The urinary fluoride excretion was increased obviously after treatment in the observation group (P < 0.01), which was superior apparently to that in the control group [(11.06 +/- 4.54) mg/L vs. (8.30 +/- 4.14) mg/L, P < 0.05]. After treatment, VAS score was reduced significantly in either group (both P < 0.01). The result in the observation group was lower remarkably than that in the control group (1.93 +/- 1.30 vs. 3.47 +/- 2.29, P < 0.01). Acupuncture achieves the significant efficacy on the promotion of urinary fluoride excretion and pain relieving of the patients with drinking-water type fluorosis in light of reinforcing kidney and activating spleen, which is superior to the oral administration of the calcium carbonate D3 tablets.

To compare healthcare utilization and costs between subjects with and without fibromyalgia (FM) using claims data from a large health benefits company in the United States. Retrospective cohort. We analyzed 24 months of medical and pharmacy claims data comparing healthcare utilization and costs among Humana members diagnosed with FM to a propensity score matched control group without a diagnosis for FM. FM cases were identified as members aged 18 years and older, with at least 2 medical claims for International Classification of Diseases, Ninth Revision, Clinical Modification codes 729.0 and/or 729.1. The first medical claim for FM was utilized as the index date. A total of 9988 FM cases and 9988 controls were included in the analysis. Compared with controls, the use of pain-related medications by FM cases was approximately 2 times higher with opioids being used most commonly. FM cases utilized a mean (SD) of 22.5 (23.9) and 31.1 (26.6) outpatient services per year in the prediagnosis and postdiagnosis periods, respectively, compared with 14.8 (20.5) and 16.3 (24.5) among controls (P <.01). Office visits, tests, and procedures represented the majority of utilization. During the postdiagnosis period, the mean per-patient per-month costs for outpatient services among FM cases was $377 ($760) and $217 ($740.87) among controls (P <.01). FM cases had significantly higher utilization and costs compared with controls. Office visits, tests and procedures, and the use of pain-related medications accounted for the largest absolute differences between the 2 groups.

Patients with gastric mucosa-associated lymphoid tissue lymphoma or diffuse large B-cell lymphoma have an increased risk of developing gastric carcinoma (GC). Identifying patients at high GC risk may lead to improved survival and prognosis. The aim of this case-control study was to evaluate whether premalignant gastric lesions are more prevalent and severe in gastric lymphoma (GL) patients with a subsequent diagnosis of GC than in those without GC. Patients with a first GL diagnosis from 1991-2008 were identified in the Dutch histopathology registry (PALGA). Cases were patients with a diagnosis of GL and a subsequent diagnosis of GC. Controls were patients with a diagnosis of GL without GC development. In total, eight cases (mean follow-up 5.5 years) and 31 controls (mean follow-up 5.3 years) were included (mean age 60 years). At lymphoma diagnosis, six (75%) cases were diagnosed with premalignant lesions, whereas in the control group, 21 (68%) had histological evidence for premalignant lesions (P=0.69). At GC diagnosis, five (63%) cases showed intestinal metaplasia in the surrounding gastric mucosa. In 22 (71%) controls premalignant lesions were present at the end of follow-up (P=0.47). No differences were demonstrated in the prevalence of premalignant lesions of cases and controls at GL diagnosis or the end of follow-up. As the prevalence of premalignant lesions is substantial in both the groups of patients, careful endoscopic surveillance of GL patients is warranted not only for recurrence of lymphoma, but also for progression to adenocarcinoma.

To examine the prevalence, characteristics and risk factors for child maltreatment among opioid-dependent persons compared to a community sample of similar social disadvantage. The study employed a case-control design. Cases had a history of opioid pharmacotherapy. Controls were frequency matched to cases with regard to age, sex and unemployment and were restricted to those with a lifetime opioid use of less than five times. The interview covered child maltreatment, family environment, drug use and psychiatric history. This study found a high prevalence of child maltreatment among both cases and controls. Despite the elevated prevalence among controls, opioid-dependent males had a higher prevalence of physical and emotional abuse; female cases had a higher prevalence and greater severity of sexual abuse. The prevalence of neglect was similar for both groups. Early parental separation was more prevalent among female cases compared to female controls; otherwise the prevalence of the risk factors was comparable for both groups. The risk factors significantly associated with child maltreatment were also similar for both cases and controls. Given the documented association between child maltreatment and adult mental disorder, child maltreatment may be an important antecedent of current psychological distress in persons presenting to treatment for opioid dependence. Apart from a possible association between early parental separation and sexual abuse among female cases, the increased prevalence of child maltreatment associated with opioid dependence did not appear to be related to differences in early childhood risk factors considered in this paper. Other risk factors may be more pertinent for those with opioid dependence. The high prevalence of child maltreatment among the opioid-dependent sample has implications for the assessment and treatment of clients presenting with opioid dependence. Assessment of child maltreatment history could help inform the development of individual treatment plans to better address those factors contributing to the development and maintenance of opioid dependence. Specifically, management of co-morbid mental disorder associated with child maltreatment could be the focus of relapse prevention programmes and also have a positive influence on treatment retention.

Consanguineous marriage is the union of individuals having at least one common ancestor. It is well established that consanguinity is a potential risk factor for many adverse health outcome of offspring. In the present case-control study we tested the hypothesis of an association between parental consanguinity marriages and risk of offspring substance abuse. The study was performed in Shiraz (Fars province, Iran). Here 156 male drug abusers (case group) and 264 randomly selected healthy blood donors, matched for age and gender as control group, were included in the study. The prevalence of parental consanguineous marriages in the studied sample was 39.1 and 28.0% among cases and controls, respectively. The difference was statistically significant. The substance abusers were more smokers and drinkers compared with the control group. There was significant negative linear trend between drug abuse and level of education. The participants stratified using drinking habits and then the analysis was carried out separately for drinker and non-drinker subjects. Among drinkers, neither before nor after adjusting for smoking status and educational level, parental consanguinity did not show association with risk of substance abuse. Among non-drinkers, after adjusting for smoking status and educational level, parental consanguineous marriage was significantly associated with increased risk of substance abuse. Our study supports a significant relationship between parental consanguinity and drug abuse among non-drinker subjects. Copyright © 2010 Elsevier Ltd. All rights reserved.

Simulation is increasingly used in medical education, promoting active learning and retention; however, increasing use also requires considerable instructor resources. Simulation may provide a safe environment for students to teach each other, which many will need to do when they enter residency. Along with reinforcing learning and increasing retention, peer teaching could decrease instructor demands. Our objective was to determine the effectiveness of peer-taught simulation compared to physician-led simulation. We hypothesized that peer-taught simulation would lead to equivalent knowledge acquisition when compared to physician-taught sessions and would be viewed positively by participants. This was a quasi-experimental study in an emergency medicine clerkship. The control group was faculty taught. In the peer-taught intervention group, students were assigned to teach one of the three simulation-based medical emergency cases. Each student was instructed to master their topic and teach it to their peers using the provided objectives and resource materials. The students were assigned to groups of three, with all three cases represented; students took turns leading their case. Three groups ran simultaneously. During the intervention sessions, one physician was present to monitor the accuracy of learning and to answer questions, while three physicians were required for the control groups. Outcomes compared pre-test and post-test knowledge and student reaction between control and intervention groups. Both methods led to equally improved knowledge; mean score for the post-test was 75% for both groups (p=0.6) and were viewed positively. Students in the intervention group agreed that peer-directed learning was an effective way to learn. However, students in the control group scored their simulation experience more favorably. In general, students' response to peer teaching was positive, students learned equally well, and found peer-taught sessions to be interactive and beneficial.

Metastatic involvement of regional lymph nodes is a major prognostic factor of colorectal cancer, which influences also its treatment strategy. International consensus foresees retrieval of ≥12 lymph nodes from colorectal specimens. The aim of the study was to assess the effect of intra-arterial staining of colorectal specimens with methylene blue on lymph node harvest. A total of 266 radically operated colorectal cancer patients were randomized into the methylene blue staining and non-staining groups. In the staining group, methylene blue solution was injected into the colorectal specimen's artery after its removal. The specimens were analysed for lymph node count, diameter and metastatic involvement. The median number of lymph nodes was higher in the staining group, 27 (95% CI 23-31%), compared with the control group, 16 (95% CI 14-19, p < 0.001). The number of examined lymph-nodes was ≥12 in 86% of the cases in the staining group and in 69% of the cases in the control group (p = 0.001). In the staining group more small-diameter (≤4 mm) lymph nodes were examined (median number 20.5 vs. 10, p < 0.001). The proportion of patients with metatatic lymph nodes was 42% in the staining group and 43% in the control group (NS). Methylene blue staining improves significantly staging accuracy through finding more small-diameter lymph nodes. It enables to detect ≥12 lymph nodes in the majority of cases. We recommend routine use of this technique in all colorectal resections with curative intent.

As epilepsy affects approximately one percent of the world population, electrical stimulation of the brain has recently shown potential for additive seizure control therapy. In this study we applied noninvasive transcranial focal stimulation (TFS) via concentric ring electrodes on the scalp of rats after inducing seizures with pentylenetetrazole (PTZ) to assess the effect of TFS on the electrographic activity. Grand average power spectral densities were calculated to compare different stages of seizure development. They showed a significant difference between the TFS treated group and the control group. In case of the TFS treated group, after TFS, the power spectral density was reduced further towards a pre-seizure "baseline" than it was for the control group. The difference is the most drastic in delta, theta and alpha frequency bands. Application of general likelihood ratio test showed that TFS significantly (p<0.001) reduced the power of electrographic seizure activity in the TFS treated group compared to controls in more than 86% of the cases. These results suggest that TFS may have an anticonvulsant effect.

To determine the sociocultural factors that have effect on spontaneous abortion in Burdur, Turkey. Study was designed as case-control study. The case group consist of 257 women whose pregnancies ended with spontaneous abortion. The control group consisted of 514 women whose pregnancy continued since 22 weeks and more during the study. Chi-square, and backward LR logistic regression were utilized in analyses. In multifactorial-analyses it was determined that four factors (educational status of women, employment status of women, exposure to physical violence and non-receipt of ANC) created independent risk on spontaneous abortions. Pregnant women with these risk factors should be followed up more frequently and in a more qualified way in primary and secondary and tertiary health institutions.

Diabetes is the most prevalent metabolic disease with a growing spread rate in word wide. Short message service (SMS) is of the most common public communication networks, which have brought about a broad spectrum of applications like social, cultural and service products in the late decade. The objective of this research is, the investigate of using SMS on diabetes patients self-caring. In an interventional study, 228 diabetes patients have been selected from a community charity. With using of random sampling method, they were divided into two groups of 114 subjects as the control and case. The case group was sent messages reminding them about sports, caring foot, taking insulin and oral tablet for 4 weeks via mobile phone. After 4 weeks, a posttest questionnaire was completed. The data analysis was performed using a descriptive statistic, Chi-square, independent t-test, and paired t-test. There are not significant differences between case and control groups before intervention by studied dependent variables (P > 0.05). Performance score mean of taking care of foot, sport and taking oral tablet and insulin in case group before intervention were 29.90, 10, 11.16 and 3.75 respectively and after intervention were 20.11, 41.36, 13.09 and 4.90, respectively. Furthermore, the performance scores mean difference after intervention, taking care of foot (P < 0.001), sport (P < 0.001), taking oral tablet (P = 0.020) was meaningful in case and control groups. Regarding the study results on using cell phone, to utilize virtual training methods is recommended as an appropriate procedure for different health care, self-caring and follow-up training plans for various groups in society, especially diabetic and chronic patients.

Limbal stem cell transplantation (LSCT) is the definitive treatment for total limbal stem cell deficiency (LSCD). This study evaluates the anatomical and visual outcomes of a surgical technique supplemented by amniotic membrane extract eye drop (AMEED) for in vivo cultivation of limbal stem cells (LSCs). One small limbal block (2 × 1 mm) harvested from the contralateral healthy eye was transferred to the diseased eye, which had been already covered by cryopreserved amniotic membrane (N = 20). The patients were categorized into case and control groups. AMEED was administered postoperatively only for patients in the case group (N = 14). Sequential penetrating keratoplasty (PKP) was performed in 4 eyes of the case group for optical clarity. Visual acuity, epithelial healing, corneal clarity and regression of conjunctivalization/vascularization were evaluated after surgery. The corneal buttons of post-PKP eyes were evaluated for LSC markers. In the case group, the mean corrected distance visual acuity (CDVA) was 20/400 before surgery, which improved to 20/40 and 20/50 at the last follow-up in eyes with and without PKP, respectively. Epithelial defects healed in all eyes of the case group during 2 weeks after surgery. Corneal conjunctivalization/vascularization regressed dramatically in all patients of the case group 2-3 months after surgery. In PKP cases, all transplanted corneas were clear at the last follow-up. LSC markers were expressed on the surface of all trephined corneal buttons. All eyes in the control group developed persistent epithelial defect. This study suggests that amniotic membrane extract may be helpful for in vivo cultivation of limbal stem cells. Copyright © 2017 Elsevier Inc. All rights reserved.

Basal Cell Carcinoma (BCC) is one of the most common skin cancers in the world and that use to lifestyle, increasing chemical pollutions, environmental factors and poor nutrition. The most important cause of this cancer is oxidative stress and free radicals so antioxidant activities for the body are so important. The aim of this study was to determine the variation of zinc and (Malondialdehyde) MDA in BCC patients. This study has been performed on case and control patients from 2013 to 2014. The samples were collected from cell carcinoma patients at Razi Hospital in Tehran, Iran. We evaluated the level of zinc with the use of Atomic Absorption Spectroscopy (AAS) method. Besides, we evaluated MDA with colorimetric assay. The concentration of MDA was significantly higher in case group in comparison to control group ( P =0.001). In addition, case group had lower concentration of zinc than the control group ( P =0.000). There was no correlation between MDA and body mass index (BMI) and between zinc and BMI. All the patients with BCC showed a significant MDA serum in comparison with control group. However, significant decrease in zinc serum of the patients was seen that is because of consuming zinc during oxidative stress process so topical use of zinc in the form of 2+ ions could be effective on antioxidant protection against the sun UV radiation.

Abnormalities in maternal folate and carbohydrate metabolism have both been shown to induce neural tube defects (NTD) in humans and animal models. However, the relationship between these two factors in the development of NTDs remains unclear. Data from mothers of children with spina bifida seen at the Unidad de Espina Bífida del Hospital Infantil Virgen del Rocío (case group) were compared to mothers of healthy children with no NTD (control group) who were randomly selected from patients seen at the outpatient ward in the same hospital. There were 25 individuals in the case group and 41 in the control group. Analysis of genotypes for the methylenetetrahydrofolate reductase (MTHFR) 677CT polymorphism in women with or without risk factors for abnormal carbohydrate metabolism revealed that mothers who were homozygous for the MTHFR 677TT polymorphism and at risk of abnormal carbohydrate metabolism were more likely to have offspring with spina bifida and high levels of homocysteine, compared to the control group. The increased incidence of NTDs in mothers homozygous for the MTHFR 677TT polymorphism and at risk of abnormal carbohydrate metabolism stresses the need for careful metabolic screening in pregnant women, and, if necessary, determination of the MTHFR 677CT genotype in those mothers at risk of developing abnormal carbohydrate metabolism.

Saliva is a complex oral biologic fluid secreted by major and minor salivary glands. Saliva has immunological, enzymatic and antioxidant defense mechanisms. Infection with human immunodeficiency virus (HIV) is a life-threatening disease. The aim of this study was to evaluate salivary vitamin C and catalase levels in HIV-positive patients in comparison to a healthy control group. Forty-nine HIV-infected individuals and 49 healthy subjects were selected. Five mL of unstimulated saliva was collected in 5 minutes using a sterilized Falcon tube with Navazesh method. Catalase and vitamin C levels were assessed by spectrophotometric assay. Data were analyzed with STATA 12. Salivary catalase levels were 7.99±2.40 and 8.37±1.81 in the case and control groups, respectively. Catalase level was lower in the case group but the difference was not statistically significant (P=0.380). Salivary vitamin C levels in the case and control groups were 3.76±1.92 and 4.87±2.20, respectively (P=0.009). HIV can alter salivary antioxidant capacity as well as vitamin C and catalase levels. Saliva may reflect serum antioxidative changes in these patients. Therefore, further research is necessary on salivary and serum oxidants and the antioxidant changes.

Although the cause of sudden sensorineural hearing loss (SSNHL) is yet to be elucidated, many theories have been proposed regarding potentially contributory etiologies. One increasingly well-supported theory purports an underlying vascular pathomechanism. If this is the case, SSNHL may also associate with conditions comorbid with vascular diseases, such as erectile dysfunction (ED). However, no studies to date have investigated the association between ED and SSNHL. This study set out to estimate a putative association between ED and having been previously diagnosed with SSNHL using a population-based dataset with a case-control design. This study used administrative claim data from the Taiwan National Health Insurance program. We identified 4,504 patients with ED as the study group and randomly selected 22,520 patients as the comparison group. Conditional logistic regression was used to examine the association between ED and having previously received a diagnosis of SSNHL. The prevalence and risk of SSNHL between cases and controls were calculated. Of the sampled patients, 41 (0.15%) had been diagnosed with SSNHL before the index date; 22 (0.49% of the cases) were from the study group and 19 (0.08% of controls) were from the control group. Conditional logistic regression analysis revealed that after adjusting for the patient's monthly income, geographic location, hypertension, diabetes, hyperlipidemia, coronary heart disease, obesity, and alcohol abuse/alcohol dependence syndrome status, patients with ED were more likely than controls to have been diagnosed with SSNHL before the index date (odds ratio = 6.06, 95% confidence interval = 3.25-11.29). There was an association between ED and prior SSNHL. The results of this study add to the evidence supporting an underlying vascular pathomechanism regarding the development of SSNHL and highlight a need for clinicians dealing with SSNHL patients to be alert to the development of ED. © 2012 International Society for Sexual Medicine.

To compare the outcomes of tubeless day care PNL using hemostatic seal in the access tract versus standard PNL. It was a prospective randomized controlled study. Cases were randomized to either the day care group with hemostatic seal (DCS) or the control group where patients were admitted and a nephrostomy tube was placed at the conclusion of surgery. A total of 180 cases were screened and out of these, 113 were included in the final analysis. The stone clearance rates were comparable in both the groups. The mean drop in hemoglobin was significantly lower in DCS group than the control group (1.05 ±0.68 vs. 1.30 ±0.58 gm/dl, p = 0.038).Mean postoperative pain score, analgesic requirement (paracetamol) and duration of hospital stay were also significantly lower in the DCS group (3.79 ±1.23 vs. 6.12 ±0.96, 1.48 ±0.50 vs. 4.09 ±1.11 grams and 0.48 ±0.26 vs. 4.74 ±1.53 days respectively; p <0.05). The incidence of urine leakage through the access tract site was significantly lower in the DCS subgroup when compared to the controls (3.6% vs. 21.1%, p <0.05). Cases in the DCS group resumed their normal activities in a significantly shorter time (8.05 ±3.05 vs.18.42 ±4.42 days; p <0.05). Higher proportion of cases in the DCS group got re-admitted, although it was not a statistically significant number (7.1% vs. 1.8%; p = 0.21). Tubeless day care PNL with composite hemostatic tract seal is considered safe. It resulted in a significant reduction of blood loss and analgesic requirement with significantly reduced hospital stay, nephrostomy tube site morbidity and time required to resume normal activity when compared to the standard PNL. However, patients must be compliant with the given instructions and should have access to a health care facility, as few of them may need re-admission.

Annual vaccination of children against seasonal influenza with trivalent inactivated influenza vaccine (TIV) has shown to be beneficial. However, this yearly practice may have unintended effect. Studies have shown that infection with wild type influenza A viruses can stimulate protective heterotypic immunity against unrelated or new influenza subtypes. We hypothesized that a consequence of yearly TIV vaccination is lack of induction of heterotypic immunity against the recent H1N1 pandemic. This was a retrospective case-control study. We reviewed the medical records of polymerase chain reaction-confirmed cases of 2009 H1N1 influenza infection in children 6 months to 18 years and a matched control group seen during the pandemic. We identified 353 polymerase chain reaction-confirmed H1N1 cases and 396 matching control subjects. Among the H1N1 group, 202/353 (57%) cases received a total of 477 doses of seasonal TIV compared with 218/396 (55%) in the control group who received a total of 435 doses. Seasonal TIV uptake was significantly higher in the H1N1 group 477/548 (87%) than in the control group, 435/532 (81%) (P = .017). Seasonal TIV uptake was significantly higher in H1N1-infected group. The finding suggests that the practice of yearly vaccination with TIV might have negatively affected the immune response against the novel pandemic H1N1 strain. Given the rarity of pandemic novel influenza viruses, and the high predictability of seasonal influenza occurrence, the practice of yearly influenza vaccination should be continued. However, the use of live attenuated intranasal vaccine, as opposed to TIV, may allow for the desirable development of a vigorous heterotypic immune response against future pandemics. © The Author(s) 2015.

Background: Considering the side effects of pharmacological methods, there has been a suggestion to use nonpharmacological methods such Aromatherapy following coronary artery bypass grafting (CABG). This study aims to evaluate the effectiveness of lavender 2% aromatherapy on sternotomy pain intensity after coronary artery bypass graft surgery in patients who have undergone surgery. Materials and Methods: During this clinical trial, 50 patients who were candidates for CABG, were randomly divided into two equal groups, that is, the control group (n = 25) and the case group (n = 25). Following CABG, the case group received two drops of 2% lavender oil every 15 minutes with supplemental oxygen and the control group received only supplemental oxygen through a face mask. The data collection tools comprised of the demographic check list and visual analog scale (VAS) for evaluating the pain intensity. The pain intensity were assessed pre- and five, 30, and 60 minutes post aromatherapy. The final data were analyzed by the t-test and chi-squared test. Results: The findings showed that the pain perception intensity in the case group was lower than that in the control group at the 30- and 60-minute phases after intervention (P < 0.0001). Conclusion: The result indicated that aromatherapy can be used as a complementary method in postoperative pain reduction, as it reduced pain. The patients require two sedative drugs, and moreover, it avoids expenses of treatment. PMID:26261829

A cohort of 4515 surgical patients in ten selected intervention groups was followed. Three hundred and seventeen developed postoperative wound infections, and 291 of these cases were matched 1:1 to controls by operation, sex and age. In comparison to the controls the cases stayed longer in hospital after the intervention and had more contact after discharge with the social security system. Using data from a national sentinel reference database of the incidence of postoperative wound infections, and using national activity data, we established an empirical cost model based on the estimated marginal costs of hospital resources and social sick pay. It showed that the hospital resources spent on the ten groups, which represent half of the postoperative wound infections in Denmark, amounted to approximately 0.5% of the annual national hospital budget. This stratified model creates a better basis for selecting groups of operations which need priority in terms of preventive measures. PMID:7925666

We describe here an approach for estimating the probability that study subjects were exposed to metalworking fluids (MWFs) in a population-based case-control study of bladder cancer. Study subject reports on the frequency of machining and use of specific MWFs (straight, soluble, and synthetic/semi-synthetic) were used to estimate exposure probability when available. Those reports also were used to develop estimates for job groups, which were then applied to jobs without MWF reports. Estimates using both cases and controls and controls only were developed. The prevalence of machining varied substantially across job groups (10-90%), with the greatest percentage of jobs that machined being reported by machinists and tool and die workers. Reports of straight and soluble MWF use were fairly consistent across job groups (generally, 50-70%). Synthetic MWF use was lower (13-45%). There was little difference in reports by cases and controls vs. controls only. Approximately, 1% of the entire study population was assessed as definitely exposed to straight or soluble fluids in contrast to 0.2% definitely exposed to synthetic/semi-synthetics. A comparison between the reported use of the MWFs and the US production levels by decade found high correlations (r generally >0.7). Overall, the method described here is likely to have provided a systematic and reliable ranking that better reflects the variability of exposure to three types of MWFs than approaches applied in the past.

To assess if the fetal electrocardiogram especially ST segment is modified by congenital heart diseases: modifications in frequencies of the different ST events and modifications in signal quality. A retrospective case-control study, comparing frequencies of the different ST events and the quality of the signal between fetuses with congenital heart diseases and fetuses without congenital heart disease. From 2000 to 2011, fifty-eight fetuses with congenital heart disease had their heart rate recording using a STAN device during labor. Control group was fetuses who were born just before a case and had a STAN as a second line for intrapartum surveillance. Cases and controls were matched on parity, gestational age at birth, presence of growth restriction and umbilical artery pH. Frequencies of the different ST event and quality of the signal were first analyzed for the global labor recording, and then separately for the first and the second phase of labor. No statistically significant difference in ST event frequencies between fetuses with congenital heart disease and the control group was found. Regarding the quality of the signal, 11.49% (±18.82) of recording time is a signal loss for fetus with congenital heart disease whereas only 5.18% (±10.67) for the control group (p=0.028). This is the first study investigating for intrapartum electrocardiogram modification in fetus with congenital heart disease. Congenital heart diseases do not modify frequencies of ST events.

To evaluate the effect of drug interaction between omeprazol and clopidogrel in hospital readmission of patients with acute coronary syndrome (ACS). Case-control study. University Clinic LeonXIII, Medellin, Colombia. We selected from a prevalent population, between 2009-2010, use of clopidogrel patients on an outpatient basis (less than one year and more than 30days), and hospital stay for ACS or the presence of a previous ACS. A case-patient was defined as one who had a recurrence of ACS and a patient-control is defined as one that no recurrence of ACS. Both groups used ambulatory prior clopidogrel due to ACS. As defined risk factor the joint use of omeprazole and clopidogrel outpatients. During the study, 1680patients clopidogrel formulated. This group identified 50cases readmitted with ACS and 76controls. No statistically significant association was found between use of clopidogrel-omeprazole and increased risk of hospital readmission for ACS (OR: 1.05; 95%CI: 0.516-2.152; P=.8851). In this small group of patients with previous SCA, the simultaneous use of clopidogrel with omeprazole does not increase the risk of a readmission by recurrence of this type of coronary event.

To evaluate the serum levels of zinc and copper in epileptic children during the long-term treatment of anticonvulsant drugs and correlate this with healthy subjects. A hospital-based group matched case-control study was conducted in the Department of Pediatrics, Faculty of Medicine, Zagazig University, Zagazig, Egypt between November 2013 and October 2014. Ninety patients aged 7.1 ± 3.6 years were diagnosed with epilepsy by a neurologist. The control group was selected from healthy individuals and matched to the case group. Serum zinc and copper were measured by the calorimetric method using a colorimetric method kit. The mean zinc level was 60.1 ± 22.6 ug/dl in the cases, and 102.1 ± 18 ug/dl in the controls (p<0.001). The mean copper level was 180.1 ± 32.4 ug/dl in cases compared with 114.5 ± 18.5 ug/dl in controls (p<0.001). Serum zinc levels in epileptic children under drug treatment are lower compared with healthy children. Also, serum copper levels in these patients are significantly higher than in healthy people. No significant difference in the levels of serum copper and zinc was observed in using one drug or multiple drugs in the treatment of epileptic patients.

Logistic regression based propensity score matching is a widely used method in case-control studies to select the individuals of the control group. This method creates a suitable control group if all factors affecting the output variable are known. However, if relevant latent variables exist as well, which are not taken into account during the calculations, the quality of the control group is uncertain. In this paper, we present a statistics-based research in which we try to determine the relationship between the accuracy of the logistic regression model and the uncertainty of the dependent variable of the control group defined by propensity score matching. Our analyses show that there is a linear correlation between the fit of the logistic regression model and the uncertainty of the output variable. In certain cases, a latent binary explanatory variable can result in a relative error of up to 70% in the prediction of the outcome variable. The observed phenomenon calls the attention of analysts to an important point, which must be taken into account when deducting conclusions.

To study whether infertile patients with endometriosis have a higher prevalence of endometrial polyps, and to clarify the characteristics of the pathology of combined polyps. Infertile patients who had undergone both hysteroscopy and laparoscopy in Reproductive Hospital Affiliated with Shandong University from January 2014 to May 2017 were enrolled. Patients with and without endometriosis, diagnosed by laparoscopy, were staged and included in the study group and control group, respectively, and the prevalence of polyps was compared. The pathological types of endometrial polyps were analyzed. A total of 414 cases were enrolled in the study group and 3,048 cases in the control group; polyps were diagnosed, with endoscopy, in 1,107 patients. Endometrial polyps were detected by hysteroscopy in 47.83% of the endometriosis group and 29.82% of the control group. The prevalence of endometrial polyps was significantly higher in the endometriosis group than in the control group (p < 0.001) but not significantly different between stages of endometriosis (p = 0.580). The pathological diagnosis included 899 endometrial polyps and 208 polypoid hyperplasia; 66.5% of endometrial polyps were combined with simple hyperplasia. The infertile patients with endometriosis had a higher prevalence of endometrial polyps, and those polyps are often combined with simple hyperplasia. © 2018 S. Karger AG, Basel.

Purpose This study aims to investigate Saccharomyces boulardii CNCM I-745 during Helicobacter pylori eradication in children. Methods One hundred ninety-four H. pylori positive children were randomized in two groups. Therapy (omeprazole+clarithromycin+amoxicillin or omeprazole+clarithromycin+metronidazole in case of penicillin allergy) was given to both groups during two weeks. In the treatment group (n: 102) S. boulardii was added to the triple therapy, while the control group (n: 92) only received triple therapy. The incidence, onset, duration and severity of diarrhea and compliance to the eradication treatment were compared. A 13C urea breath test was done 4 weeks after the end of eradication therapy in two groups of 21 patients aged 12 years and older to test the H. pylori eradication rate. Results In the treatment group, diarrhea occurred in 12 cases (11.76%), starting after 6.25±1.24 days, lasting 3.17±1.08 days, and compliance to eradication treatment was 100%. In the control group, diarrhea occurred in 26 cases (28.26%), starting after 4.05±1.11 days, lasting 4.02±0.87 days, and in six cases eradication treatment was stopped prematurely (p<0.05). The 13C urea breath test showed successful H. pylori eradication in 71.4% of the patients in the treatment and in 61.9 % in the control group (not significant). Conclusion S. boulardii has a beneficial effect on the prevention and treatment of diarrhea during H. pylori eradication in children. Although S. boulardii did only slightly increase H. pylori eradication rate, compliance to eradication treatment was improved. PMID:25866729

The aim of this study was to detect the presence of Helicobacter pylori and its virulent cagA genes in the oral cavity of individuals with upper gastric diseases. Sixty-two individuals (42+/-2.3 years) with dispepsy symptoms, referred for gastroscopy and who were H. pylori positive in the gastric biopsy, were recruited and separated in two groups: case group-individuals with gastric disease (n = 30); control group-individuals with no gastric disease (n = 32); saliva, dental plaque and biopsy samples were collected from all individuals. Oral and biopsy samples were analyzed by PCR using specific primers for H. pylori 16S ribosomal and cagA genes. PCR products were sequenced for DNA homology confirmation. H. pylori was detected neither in dental plaque nor in saliva in the control group. In the case group H. pylori DNA was detected in 16/30 (53.3%) saliva samples and in 11/30 (36.6%) dental plaque samples. The cagA gene was detected in 13/30 (43.3%) gastric biopsies, in 7/16 (43.8%) saliva samples, and in 3/11 (27.3%) dental plaque samples. Eighteen (60.0%) individuals in the case group were H. pylori positive both in oral and biopsy samples, and 8 (26.6%) of those were positive for cagA-H. pylori DNA. H. pylori and its virulent clone showed a higher prevalence in the oral cavity of individuals in the case group than in the control group (p < 0.05). Our results suggest that dental plaque and saliva may serve as temporary reservoir for H. pylori and its virulent cagA variant in individuals with gastric disease.

A large variety of adverse reactions are well known to frequently occur during chemotherapy and radiotherapy in oncology. Specific medications exist to target individual side effects. The aim of this study was to explore in a pilot trial whether supplementation with French maritime pine bark extract Pycnogenol could alleviate side effects and improve patient's quality of life. Cancer patients who previously underwent surgery and who were in view of their pathology in relatively good condition, both physically and psychologically, were recruited for this study and divided into two groups. These patients received their first cycle of radiotherapy or chemotherapy, which lasted from 10 days up to 1 month. Then one group of patients received 150 mg Pycnogenol, the control group comparable placebo in a single-blinded fashion. The authors studied the occurrence of side effects and made attempts to judge their severity on a semi-quantitative visual analogue scale over a 2 months period starting after patients completed their first cycle of chemo- or radiotherapy, respectively. Twenty five radiotherapy patients receiving Pycnogenol showed a decreased frequency of essentially all investigated side-effects as compared to 21 patients receiving placebo, though in many categories the difference was limited. The most apparent improvements of acute side effects related to decreased soreness and ulceration in the mouth and throat as well as less dryness of the mouth and the eyes. A decreased incidence of nausea /vomiting, diarrhoea, edema and weakness was noticed, which was reflected by semi-quantitative evaluation suggesting that severity was only half or even less pronounced than in the control group. Only one case of deep vein thrombosis occurred in the Pycnogenol group whereas 2 cases of superficial vein thromboses and one case of deep vein thrombosis occurred in the control group (2.9% vs 10%). Thirty four chemotherapy patients were supplemented with Pycnogenol and another 30 patients were in the control group. For all patients this was the first chemotherapy treatment period. The Pycnogenol group presented with a lowered incidence of all investigated side effects as compared to the control group, though in many cases to a limited extent. The most prominent improvements were found for nausea, vomiting, diarrhoea and weight loss. Semi-quantitative evaluation showed that here again symptom severity was half or less pronounced than in the control group. Various further symptoms improved such as cognitive impairment and also cardiotoxicity and neutropenia. Effects on anemia could not be investigated as several patients received erythrocyte transfusion. In the Pycnogenol group one case of superficial vein thrombosis was indentified while 3 cases of superficial vein thromboses and one deep vein thrombosis were detected in the control group (4% vs 19%). In both chemotherapy and radiotherapy patients Pycnogenol lowered the requirement for medication to address side effects. This was reflected by less days of hospitalisation the patients required. The authors did not investigate a possible interference with the anti-neoplastic efficacy of chemo- and radiotherapy. This possibility requires attention in future studies with Pycnogenol. From their previous clinical experience the authors suggest that alleviation of side effects described in this study results from Pycnogenol activities related to endothelial protection, and anti-inflammatory anti-edema activities. The results of this pilot trial warrant further prospective studies with larger number of patients to validate benefits more specifically with regard to type of malignancy and treatment regimen.

Introduction: Acute skin wound healing is a complicated process comprising various phases. Recent animal studies have shown that steroid sex hormones such as estrogen maybe helpful in the regulation of several pathophysiologic stages that are involved in wound healing. In this study we examined the effects of topical estrogen in the treatment of traumatic facial wounds. Materials and Methods: Patients referred to Luqman Hospital, Tehran with traumatic wounds were enrolled in this case-control study into two groups of equal size. From the second week of the study, topical estrogen (0.625 mg conjugated topical estrogen ointment) was administered in the case group, while the control group received a Eucerin dressing only. The two groups were then compared in terms of wound healing rate on Day 7,14, and 30. Results: Thirty patients with mean age of 16.02+36.23 years were compared in the control and estrogen-treated groups. After treatment, no scars or keloids were observed in either group. The wound area in the estrogen group was lower than that in the control group on Day 14 and 30, but the difference was not significant (P>0.05). Healing rates in the control group on Day 14 (7.1+42.3 vs.50.3+4.9 mm2) and Day 30 (1.9+93.5 vs. + 97.3+0.6 mm2) (were lower than those in the estrogen group, but the differences were not significant (P>0.05). Findings show that the required time for wound healing in the estrogen-treated group was lower than that in the control group, but the difference was not significant (P>0.05). Conclusion: Based on this study, topical estrogen has no effect on the rate of wound healing or the rate of wound area. PMID:26878003

Purpose: We initially reported the radiation-attenuating effect of silicone oil 1000 centistokes for iodine 125. The purpose of this report was to compare the clinical outcomes in case patients who had iodine 125 brachytherapy with vitrectomy and silicone oil 1000 centistokes with the outcomes in matched control patients who underwent brachytherapy alone. Methods and Materials: Consecutive patients with uveal melanoma who were treated with iodine 125 plaque brachytherapy and vitrectomy with silicone oil with minimum 1-year follow-up were included. Control patients who underwent brachytherapy alone were matched for tumor size, location, and sex. Baseline patient and tumor characteristics and tumor response tomore » radiation, final visual acuity, macular status, central macular thickness by ocular coherence tomography (OCT), cataract progression, and metastasis at last follow-up visit were compared. Surgical complications were also determined. Results: Twenty case patients met the inclusion criteria. The average follow-up time was 22.1 months in case patients and 19.4 months in control patients. The final logMAR vision was 0.81 in case patients and 1.1 in control patients (P=.071); 8 case patients and 16 control patients had abnormal macular findings (P=.011); and the average central macular thickness by OCT was 293.2 μm in case patients and 408.5 μm in control patients (P=.016). Eleven case patients (55%) and 1 control patient (5%) had required cataract surgery at last follow-up (P=.002). Four patients in the case group and 1 patient in the control group experienced metastasis (P=.18). Among the cases, intraoperative retinal tear occurred in 3 patients; total serous retinal detachment and macular hole developed in 1 case patient each. There was no case of rhegmatogenous retinal detachment, treatment failure, or local tumor dissemination in case patients or control patients. Conclusions: With up to 3 years of clinical follow-up, silicone oil during brachytherapy for the treatment of uveal melanoma resulted in fewer abnormal maculas, lower central macular thickness on OCT, and a trend toward better final visual acuity in comparison with matched control patients who underwent brachytherapy alone.« less

We examined the effect of an instructional video about the production of diagnostic sputum on case detection of tuberculosis (TB), and evaluated the acceptance of the video. Randomized controlled trial. We prepared a culturally adapted instructional video for sputum submission. We analyzed 200 presumptive TB cases coughing for more than two weeks who attended the outpatient department of the governmental Municipal Hospital in Mwananyamala (Dar es Salaam, Tanzania). They were randomly assigned to either receive instructions on sputum submission using the video before submission (intervention group, n = 100) or standard of care (control group, n = 100). Sputum samples were examined for volume, quality and presence of acid-fast bacilli by experienced laboratory technicians blinded to study groups. Median age was 39.1 years (interquartile range 37.0-50.0); 94 (47%) were females, 106 (53%) were males, and 49 (24.5%) were HIV-infected. We found that the instructional video intervention was associated with detection of a higher proportion of microscopically confirmed cases (56%, 95% confidence interval [95% CI] 45.7-65.9%, sputum smear positive patients in the intervention group versus 23%, 95% CI 15.2-32.5%, in the control group, p <0.0001), an increase in volume of specimen defined as a volume ≥3ml (78%, 95% CI 68.6-85.7%, versus 45%, 95% CI 35.0-55.3%, p <0.0001), and specimens less likely to be salivary (14%, 95% CI 7.9-22.4%, versus 39%, 95% CI 29.4-49.3%, p = 0.0001). Older age, but not the HIV status or sex, modified the effectiveness of the intervention by improving it positively. When asked how well the video instructions were understood, the majority of patients in the intervention group reported to have understood the video instructions well (97%). Most of the patients thought the video would be useful in the cultural setting of Tanzania (92%). Sputum submission instructional videos increased the yield of tuberculosis cases through better quality of sputum samples. If confirmed in larger studies, instructional videos may have a substantial effect on the case yield using sputum microscopy and also molecular tests. This low-cost strategy should be considered as part of the efforts to control TB in resource-limited settings. Pan African Clinical Trials Registry PACTR201504001098231.

Psychosocial factors have been linked to the development and progression of cancer and shown to be relevant in cancer care. However, the evidence that psychosocial interventions affect cancer survival is less conclusive. Few methodologically sound studies have addressed this issue. To investigate the effects of a 6-week psychosocial intervention on survival among patients with stage I breast and prostate cancer. Matched case-control. 3 rural hospitals or cancer centers in central Pennsylvania. 21 breast and 29 prostate stage I cancer patients (treatment group) matched with 74 breast and 65 prostate stage I cancer patients from the same hospitals who did not receive the intervention (control group). Six 2-hour health psychology classes conducted by a licensed staff psychologist. Survival time was compared between the 2 groups and with national norms. The intervention group lived significantly longer than did matched controls. At 4- to 7-year follow-up (median = 4.2 years), none of the breast cancer patients in the intervention group died, whereas 12% of those in the control group died. Twice as many matched-control prostate cancer patients died compared with those in the intervention group (28% vs 14%). Control group survival was similar to national norms. These results are consistent with prior clinical trials and suggest that short-term psychosocial interventions that encourage the expression of emotions, provide social support, and teach coping skills can influence survival among cancer patients. However, self-selection bias cannot be ruled out as an alternative explanation for the results. These interventions merit further consideration and research.

To study the efficacy and safety of acupuncture therapy for the improvement of sleep quality of outpatients receiving methadone maintenance treatment (MMT). Using randomized double-blinded controlled design, seventy-five MMT outpatients with low sleep quality [score of Pittsburgh sleep quality index (PSQI) > or = 8], were randomly assigned to the acupuncture group (38 cases) and the sham-acupuncture group (37 cases). All patients maintained previous MMT. Acupuncture was applied to Baihui (GV20), Shenmen (bilateral, TF4), Shenting (GV24), Sanyinjiao (bilateral, SP6), and Sishencong (EX-HN1) in the acupuncture group. The same procedures were performed in the sham-acupuncture group, but not to the acupoints (5 mm lateral to the acupoints selected in the acupuncture group) with shallow needling technique. The treatment was performed 5 times each week for 8 successive weeks. The PSQI was assessed before treatment, at the end of the 2nd, 4th, 6th, and 8th week of the treatment. The detection ratio of low sleep quality and the incidence of adverse acupuncture reactions were compared between the two groups at the end of the 8th week. The overall PSQI score was obviously higher in the acupuncture group than in the sham-acupuncture group with statistical difference (P < 0.01). The detection ratio of low sleep quality at the end of the 8th week was lower in the acupuncture group (60.53%, 23/38 cases) than in the sham-acupuncture group (83.78%, 31/37 cases) with statistical difference (P < 0.05). The rate of adverse acupuncture reaction was 5.26% (2/38 cases) in the acupuncture group and 2.70% (1/37 cases) in the sham-acupuncture group respectively, showing no statistical difference (P > 0.05). Acupuncture therapy could effectively and safely improve the sleep quality of outpatients receiving MMT.

Several studies have previously been performed to promote kidney healing after injuries. Objectives: The aim of this study was to investigate the effect of zinc on renal healing after traumatic injury in rats. Forty healthy female rats were selected and one of their kidneys was incised. Half of the incisions were limited only to the cortex (renal injury type I) and the other ones reached the pelvocalyceal system of the kidney (renal injury type II). All the rats in the zinc treated group (case group) received 36.3 mg zinc sulfate (contained 8.25 mg zinc) orally. After 28 days, the damaged kidneys were removed for histopathological studies. In the rats with type I injury, kidney inflammation of the case group was significantly lower than that of the control group. However, the result was not significant in rats with type II injury. Tissue loss and granulation tissue formation were significantly lower in the case group than the control group in both type I and II kidney injuries. Overall, Zinc can contribute to better healing of the rat's kidneys after a traumatic injury.

The purpose of our study was to investigate the radiographic characteristics of atypical femoral shaft fractures (AFSFs) in females with a particular focus on femoral bow and cortical thickness. We performed a fracture location-, age-, gender-, and ethnicity-matched case-control study. Forty-two AFSFs in 29 patients and 22 typical osteoporotic femoral shaft fractures in 22 patients were enrolled in AFSF group and control group, respectively. With comparing demographics between two groups, radiographically measured femoral bow and cortical thicknesses of AFSF group were compared with control group. All AFSF patients were females with a mean age of 74.4 years (range, 58-85 years). All had a history of bisphosphonate (BP) use with a mean duration of 7.3 years (range 1-17 years). Femoral bow of AFSF group was significantly higher than control group on both anteroposterior (AP) and lateral radiographs after age correction. Mean femoral bow on an AP radiograph was 12.39° ± 5.38° in AFSF group and 3.97 ± 3.62° in control group ( P < 0.0001). Mean femoral bow on the lateral radiograph was 15.71° ± 5.62° in AFSF group and 10.72° ± 4.61° in control group (after age correction P = 0.003). And cortical thicknesses of AFSF group demonstrated marked disparity between tensile and compressive side of bowed femurs in this study. An adjusted lateral cortical thickness was 10.5 ± 1.4 mm in AFSF group and 8.1 ± 1.3 mm in control group (after age correction P < 0.0001) while medial cortical thickness of AFSF group was not statistically different from control group. Correlation analysis showed that the lateral femoral bow on the AP radiograph was solely related to lateral CTI ( R = 0.378, P = 0.002). AFSFs in female BP users were associated with an increased anterolateral femoral bow and a thicker lateral cortex of femurs.

Introduction Surgical services are increasingly seen to reduce death and disability in Sub-Saharan Africa, where hospital-based mortality remains alarmingly high. This study explores two implementation approaches to improve the quality of perioperative care in a Tanzanian hospital. Effects were compared to a control group of two other hospitals in the region without intervention. Methods All hospitals conducted quality assessments with a Hospital Performance Assessment Tool. Changes in immediate outcome indicators after one and two years were compared to final outcome indicators such as Anaesthetic Complication Rate and Surgical Case Fatality Rate. Results Immediate outcome indicators for Preoperative Care in the intervention hospital improved (52.5% in 2009; 84.2% in 2011, p<0.001). Postoperative Inpatient Care initially improved to then decline again (63.3% in 2009; 70% in 2010; 58.6% in 2011). In the control group, preoperative care declined from 50.8% (2009) to 32.8% (2011, p <0.001), while postoperative care did not significantly change. Anaesthetic Complication Rate in the intervention hospital declined (1.89% before intervention; 0.96% after intervention, p = 0.006). Surgical Case Fatality Rate in the intervention hospital declined from 5.67% before intervention to 2.93% after intervention (p<0.0010). Surgical Case Fatality Rate in the control group was 4% before intervention and 3.8% after intervention (p = 0.411). Anaesthetic Complication Rate in the control group was not available. Discussion Immediate outcome indicators initially improved, while at the same time final outcome declined (Surgical Case Fatality, Anaesthetic Complication Rate). Compared to the control group, final outcome improved more in the intervention hospital, although the effect was not significant over the whole study period. Documentation of final outcome indicators seemed inconsistent. Immediate outcome indicators seem more helpful to steer the Continuous Quality Improvement program. Conclusion Specific interventions as part of Continuous Quality Improvement might lead to sustainable improvement of the quality of care, if embedded in a multi-faceted approach. PMID:26327392

Placental growth factor (PlGF) is a pro-angiogenic factor mainly assessed in preeclampsia in which its blood concentration is decreased. The aim of this study was to dose the blood concentration of PlGF in women with fetal intra-uterine growth restriction (IUGR) without associated preeclampsia at the time of diagnosis. Case/control study: IUGR was defined by a fetal biometry with abnormal uterine and/or umbilical doppler (n=23). This group was compared to a control group of fetuses (n=25) matched for gestational age at blood sampling for the dosage of maternal seric PlGF. Women with preeclampsia were not included. The plasma PlGF concentration was 11pg/mL (IQR [11-42,8]) in the IUGR group vs 287pg/mL [135-439] in the control group (P<0.001) and this difference was available after adjustment for gestational age at the time of blood sampling (P<0.001). PlGF sensitivity and specificity for discrimination were respectively 87% (CI 95% [66-97]) and 88% (CI 95% [69-97]). Maternal serum PlGF concentrations were very low in IUGR group compared with those of the control group. Copyright © 2015. Published by Elsevier SAS.

A trial was performed on a farm in the Coast Province of Kenya to study the effects of East Coast fever immunisation and different acaricidal treatments on the productivity of immunised and unimmunised beef cattle. Eighty cattle were immunised against Theileria parva parva (Marikebuni) by the infection and treatment method and a similar group was left as an unimmunised control. Immunisation had no deleterious effect on the cattle. After immunisation, the immunised and control groups were each subdivided into four groups of 20 and each subgroup was managed under a different tick control regimen. The tick control regimen were, acaricidal spraying twice a week or once every three weeks, the application of acaricide-impregnated ear-tags, and no tick control. During a nine-month exposure period there were 18 cases of East Coast fever among the 80 immunised cattle, three which were severe and the others mild. Among the 80 unimmunised cattle there were 57 cases of East Coast fever, 50 of which were severe. The highest morbidity and mortality occurred in the groups under limited tick control or without tick control. Overall weight gain in the immunised cattle, irrespective of the tick control regimen, was better than the weight gain in the unimmunised groups. Within the immunised groups, the weight gain of the cattle sprayed twice weekly was comparable to the weight gain of the animals with acaricidal ear-tags and was significantly higher than the weight gains in the groups sprayed once every three weeks or with tick control. Preliminary cost/benefit analysis showed that it was uneconomical to maintain unimmunised cattle under limited or no tick control.(ABSTRACT TRUNCATED AT 250 WORDS)

Human Papilloma Virus has a strong relation to oropharyngeal mucosa and is considered to be responsible for a wide range of upper respiratory tract pathologies, like laryngeal papilloma. There's a hypothesis, that it plays a significant role in middle ear chronic inflammations and neoplasm's. MATERIAL AND METHODIC. The examination was carried on a group of 53 patients, 39 of which was suffering from granulation tissue chronic otitis media, 7-cholesteatomatous otitis media, 6--middle ear malignant neoplasm, and 1 middle and/or external ear benign neoplasm. The control group consisted of 5 patients operated on: otosclerosis--4 cases and post-traumatic tympanic membrane perforation--1 case. The material was postoperative tissue, like polyps, inflammatory granulation tissue, cholesteatoma masses and malignant neoplasm's tissue. In the whole group of 53 examined cases, HPV DNA was confirmed in 22 cases (41.5%), in that group oncogenic types 16 or 18 in 12 cases (22.6%), and in 14 cases (26.4%) types 6 or 11. In a group of chronic granulomatous otitis media DNA characteristic for Papilloma was identified in 12 cases (25.6%), in it in 9 cases DNA HPV type 6 or 11 was confirmed, and in 7 cases type 16 or 18. Among cholesteatomatous chronic otitis media HPV DNA types 6 or 11 was identified in 70%. In every case of middle ear malignant neoplasm a presence of high-risk DNA Papilloma types 16 or 18 was confirmed. In any case of control group HPV DNA was detected. The results has been compared with other authors examinations and it is claimed that they confirm the observation, that Human Papilloma Viruses may be a factor, that might play an important role in pathology of chronic otitis media and ear neoplasm's. It is concluded, that differences in percentages of HPV presence in chronic inflammations (70%) and ear neoplasm's may be explained by viral co-infection during bacterial c. o. m. Viral infection probably evolves carcinogenesis, which leads to a neoplastic growth.

The expression of heat shock proteins (hsp) increases in case of variable types of endogenous and exogenous cellular stress, as for example thermal stress. Immunohistochemical staining with hsp antibodies can visualize these stress proteins. Fifty-three cases of death due to heat and a control group of 100 deaths without any antemortem thermic stress were examined regarding hsp27 and hsp70 expression in myocardial, pulmonary, and renal tissues. The results revealed a correlation between hsp expression, survival time, and cause of death. In cases of death due to fire, the expression of hsp is more extensive than in the control group, especially in pulmonary and renal tissues. The immunohistochemical investigation of an hsp expression can support the proof of vitality in cases of death related to fire.

Chronic obstructive parotitis (COP) is a common disease of the parotid gland. A total of 104 patients with COP were identified and randomized into a treatment group (52 cases) and a control group (52 cases). All patients underwent sialography and salivary gland scintigraphy (SGS) examinations before surgery. The patients in the treatment group received chymotrypsin combined with gentamicin via interventional sialendoscopy to irrigate the duct, and the control group received gentamicin alone. All patients were asked to record their pain on a visual analogue scale (VAS) before treatment and at 1 week, 2 weeks, 1 month, 3 months, and 6 months after surgery. The VAS score for pain intensity was decreased at 1 week post-treatment in both groups (P<0.05). Compared to the control group, the VAS score was lower in the treatment group at 1 week, 2 weeks, and 1 month post-treatment (P<0.05). The 6-month postoperative SGS results showed improved uptake and excretion in both groups (P<0.05). The treatment group exhibited higher scores for postoperative SGS excretion than the control group (P<0.05). The administration of chymotrypsin combined with gentamicin by sialendoscopy is effective for the treatment of non-stone-related COP and specifically improves the excretion function of the parotid gland.

Vitamin D deficiency is seen in a high proportion of people with established psychotic disorders, but it is not known if this is present at onset of the illness. We set out to examine vitamin D levels in people with their first episode of psychosis (FEP). We conducted a matched case-control study to examine vitamin D levels and rates of vitamin D deficiency in sixty nine patients presenting with their FEP and sixty nine controls matched for age, sex and ethnicity. Differences between groups were tested using student's-t tests, paired t-tests and odds ratios for further analysis. Vitamin D levels were significantly lower in cases than in controls (p<0.001). The odds ratio of being vitamin D deficient was 2.99 in the FEP group relative to the control group. There was no correlation between vitamin D levels and length of hospitalisation in the patient group (r=-0.027, p=0.827). We found higher rates of vitamin D deficiency in people with FEP compared to matched controls. Given that vitamin D is neuroprotective; that developmental vitamin D deficiency may be a risk factor for psychosis, and that incipient psychosis may affect lifestyle factors and diet, future studies are required to examine this association further. In the meantime, there is a need for more widespread testing of vitamin D levels in FEP and for the development of appropriate management strategies. © 2013 Elsevier B.V. All rights reserved.

We investigated whether employment as a welder with potential exposure to manganese and other substances is associated with Parkinson disease (PD), parkinsonism or related neurological disorders, or accelerates the age of onset of PD. We selected cases and controls from 12,595 persons ever employed at three Caterpillar Inc. (CAT) plants between 1976 and 2004 with potential to make a medical insurance claim between 1998 and 2004. Cases had filed a claim for 1) PD, 2) "secondary parkinsonism", 3) "other degenerative diseases of the basal ganglia" or 4) "essential and other specific forms of tremor". Cases were grouped by claims: Group 1-claims 1 and 2 and Group 2-claims 1 to 4, and as study period incident (SPI) or prevalent. Each case was matched to two series of 10 controls each on date of case's first claim, year of birth, race and sex. Series I was also matched on plant. Odds ratios (OR) and 95% confidence intervals (CI) for the variable, "ever welder in any CAT plant" were: Group 1-SPI Cases: Series I (OR = .76, CI = .26-2.19), Series II (OR = .81, CI = .29-2.25); Group 1- Prevalent Cases: Series I (OR = .82, CI = .36-1.86), Series II (OR = .97, CI = .42-2.23); Group 2- SPI Cases: Series I (OR = 1.03, CI = .57-1.87), Series II (OR = 1.21, CI = .67-2.20) Group 2-Prevalent Cases: Series I (OR = 1.02, CI = .62-1.71), Series II (OR = .86, CI = .51-1.43). Our finding of no statistically significant associations for welding employment was maintained following adjustment for potential confounding and evaluation of possible effect modification. Employment as a welder did not accelerate the age of onset of PD. Our study supported the conclusion that employment as a welder is not associated with Parkinson disease, parkinsonism or a related neurological disorder.

The use of Toombak has been reported to play a major role in the etiology of oral cancer in Sudan. The cellular proliferative activity on the oral epithelium of 210 Toombak dippers was assessed by applying the micronuclei frequency, mean argyrophilic nucleolar organizer region (AgNOR) counts, Papanicolaou method, and 1% crystal violet stain. Participants were divided into 3 groups: 200 were apparently healthy individuals, 100 were Toombak users (cases), 100 were non-tobacco users (control) and 10 were patients with oral squamous cell carcinomas. Cytological atypia was identified among 4 (4%). Toombak users and was not found among the control group (P<0.04). The micronuclei frequencies were higher in Toombak users (1.026) than in the control group (0.356) (P<0.0001). The mean AgNOR counts in Toombak users (2.423) were higher than control group (1.303) (P<0.0001). Neither Toombak users nor control group showed mitotic figures in 1% crystal violet method. The results of this research showed that Toombak dipping is a high risk factor for increase in the cellular proliferation in the oral mucosa. The cytological proliferative marker methods used are useful for screening Toombak users. PMID:24179643

The aim of this case-control study conducted in Belgrade during 1994-1997 was to investigate whether parental demographic characteristics and habits are associated with insulin-dependent diabetes mellitus (IDDM). Case group comprised 105 children up to 16 years old with IDDM and control group comprised 210 children with skin diseases. Cases and controls were individually matched by age (+/- one year), sex and place of residence (Belgrade). According to chi 2 test results, children with IDDM significantly had five or more family members and they also significantly more frequently had poor socio-economic status than their controls. Higher education of fathers was significantly more frequently reported in diabetic children, in comparison with their controls. Parents of diabetic children were significantly more frequently occupationally exposed to radiation, petroleum, and its derivates, organic solvents, dyes and lacquers. During pregnancy mothers of diabetic children significantly more frequently smoked cigarettes and consumed coffee, coca-cola, alcohol and foods containing nitrosamines. Fathers of diabetic children more frequently consumed alcohol.

Retinopathy of Prematurity (ROP) is a proliferative vitreoretinopathy which is one of the most frequent causes of blindness in children. In an attempt to find a solution to this important problem in preterm children, the search for new, effective treatment modalities with fewer side effects is underway. In our study, which was planned for this reason, we aimed to investigate the effects of propranolol treatment applied to cases of ROP in various stages during the second phase (known as the neovascularization-hypoxia phase) and to determine the correlation of these effects with the platelet mass index (PMI). A total of 171 preterm infants at risk of ROP were selected randomly for inclusion in the study. All of the patients were classified according to their stage of ROP and were divided into control and treatment groups. While the cases in the control group were administered physiological saline solution, those in the treatment group were administered propranolol in the period that corresponded to the second stage of the disease. The thrombocyte and PMI values in the first and second stages of each study group were recorded. A significant difference was found between the control and treatment groups of the stage 2 ROP study subjects. In the stage 2 ROP study group, no significant difference was detected between the control and treatment cases in terms of platelet counts in phase 1 or in the PMI values and the thrombolytic counts in phase 2. On the other hand, in phase 2 of the stage 2 ROP study subjects significant differences were detected between the control and treatment group in terms of PMI values. In the study, it was found in the stage 2 ROP study group that propranolol reduced the need for laser photocoagulation significantly. Also, in parallel to the efficacy of propranolol in this study group, a decrease was observed in PMI values.

Objective: To explore the relativity between cytokines such as IL-8,TNF-α,VEGF and psoriasis and the influence on its variation by ILLLI.Methods:47 patients with psoriasis were divided into 5 groups ,treated with ILLLI( 1h per day , a course of treatment is 10 days),observed the variation of IL-8,TNF-a and VEGF in peripheral blood of patients with psoriasis between pre and post treatment and compared with the control. Results: 1. In each case of psoriasis, the concentration of IL-8 in blood was significantly higher than that of control group. After treatment, the concentrations of A group, B group and C group were decreased significantly, which were close to the control. The related statistical analysis showed significant difference. Among them, A group decreased most significantly; Although there is no significant difference in concentration of IL-8 of D group and E group between pre and post treatment, the trend of them became to keep decreasing. In each case of psoriasis, the concentration of TNF-a in blood was much lower than that of control group. The concentration of TNF-a in A?C?D group increased significantly as compared with pre-irradiation except that in E group. In cases, the concentrations of VEGF in blood were much higher than that of control group. In each group, there was no difference in VEGF concentration between pre and post irradiation. Conclusions: The decrease of IL-8 induced by ILLLI might be related with its immunosuppressive function. It suppressed the activity of CD4+T cell which could secrete a great deal of IL-8 and play an important role to the tache of psoriasis onset. So in the psoriasis patients who were treated with ILLLI, the production of TNF-a could be suppressed. In patients, the increasing of VEGF might be related with the increasing of IL-8. There was no difference of it between pre and post ILLLI treatment might because VEGF was not the action target of ILLLI.

To study the gene copy number, mRNA transcription and protien expression of programmed cell death 1 (PD-1) gene in primary hepatocellular carcinoma (PHC) patients and normal control individuals (NC) who are anti-HBs positive, and to investigate the variations in PD-1 gene copy numbers and its relationship with PHC. Real-time PCR was adopted to detect the PD-1 gene copy numbers and their mRNA expressions in peripheral blood mononuclear cells (PBMCs) from 24 samples of PHC patients and 26 of NC. Protein expression level of PD-1 on CD8+ T was analyzed by flow cytometry. In terms of number of PD-1 gene copy numbers, the percentage of cases of haploid (single) was 34.62% and 4.17% in PHC group and control group respectively while the percentage of cases of diploid (double) was 61.54% and 95.83% respectively. The difference between the two was statistically significant (chi2 = 7.639, P = 0.006). The rate of cases with double PD-1 gene copy numbers was found to be higher in patients with PHC than in control group. It was also found that the average expression of PD-1 mRNA was 2.35E-03 in control group and 1.23E-03 in PHC group. The expression level was significant lower in PHC group than that in control group when compared by using Mann-whitey technic (U = 153, P = 0.009). Furthermore, the frequency of PD-1 protein expression on CD8+ T cells was 3.72 +/- 0.32 in control group and 16.13 +/- 1.68 in PHC group. The level of PD-1 mRNA expression was higher in PHC and significant differences was shown between two groups (t = -7.073, P = 0.000). Our study suggests that the variation in PD-1 gene copy number may trigger primary hepatocellular carcinoma to HBV carriers. The relationship between the variation of PD-1 gene copy numbers and its association with primary hepatocellular carcinoma is worth further focus.

It has been shown that 3 days of 62 mg/kg/day deferoxamine infusion (maximum dose not to exceed 6000 mg/day) is safe and tolerated by intracerebral hemorrhage (ICH) patients. The aim of this study was to investigate the efficacy of deferoxamine mesylate for edema resolution and hematoma absorption after ICH. From February 2013 to May 2014, spontaneous ICH patients diagnosed by computed tomography (CT) within 18 hours of onset were evaluated. Patients were randomly divided into two groups: an experimental group and a control group. The treatment of the two groups was similar except that the experimental group received deferoxamine mesylate. Patients were evaluated by CT and neurology scale at the time of admission, and on the fourth, eighth, and fifteenth day (or at discharge) after admission. Patients were followed up for the first 30 days and clinical data of the two groups were compared. Forty-two patients completed 30 days of follow-up by May 2014; 21 cases in the experimental group and 21 cases in the control group. The control group's relative edema volume on the fifteenth day (or discharge) was 10.26 ± 17.54, which was higher than the experimental group (1.91 ± 1.94; P < 0.05). The control group's 1-8 day and 8-15 day relative hematoma absorption were greater than the experimental group (P < 0.05).The control group's relative edema volume on the fourth, eighth, and fifteenth day (or discharge) was higher than the experimental group (P < 0.05). Neurological scores between the two groups were not statistically different on the fifteenth day (or discharge) or on the thirtieth day. Deferoxamine mesylate may slow hematoma absorption and inhibit edema after ICH, although further investigation is required to form definitive conclusions.

Dengue Hemorrhagic Fever (DHF) is an acute infectious disease caused by dengue virus and transmission of the virus is mediated by mosquitoes bites [1]. Host immunity against dengue infection is affected by nutrient adequacy which is depending on nutrient intake [2]. The aim of this study was to determine nutrient intake of DHF patients in Semarang city. The DHF sample cases were obtained from three hospitals in Semarang city (n=48), from the period of March to May 2016 and the control groups were obtained from healthy respondents with matched age, sex, and district location (n=48). Nutrient intake were obtained by food recall and calculated using Nutrisurvey Indonesia. Afterwards, the result of the nutrisurvey will be compared to Indonesian daily value according to Permenkes no. 75 about daily value based on age and gender. The results showed that both in cases and control groups the macro-(energy, carbohydrate, protein, fat) and micro-nutrient (vitamins A., C, B1, B2, B6, calcium, magnesium, phosphorus, zinc, and Iron) intake were below 80% of nutrient adequacy. No correlation was found between nutrient adequacy and DHF cases. We find that macro and micronutrient intake in DHF case and control groups are the same and below 80% of nutrient adequacy. The nutrient intake was not related to DHF cases.

To study the analgesic mechanism of Bitongxiao (BTX, a Chinese herbal decoction) in treating neck pain due to cervical spondylitis (CS). BTX and Jingfukang (JFK) granule were used to treat the treated and the control group separately in 102 CS cases. Plasma leucine enkephalin (LEK), substance P (SP) and prostaglandin E2 (PGE2) before and after treatment were assayed by radioimmunoassay (RIA). Twelve patients in the treated group were clinically cured, 36 markedly effectively, 3 effectively and 1 ineffectively, while in the control group they were 5, 33, 14 and 0 cases respectively. The cured and marked effective rate in the treated group was 92.3%, while that in the control group 72.0%. After treatment the pain score (VAS) of both groups were significantly reduced, but the reduction was higher in the treated group than that in the control. Before treatment, plasma LEK in all patients was abnormally low, but after treatment, it raised obviously more in the treated group than that in the control (P < 0.05). Plasma SP of both groups were obviously elevated, and PGE2 revealed unaltered after treatment. BTX has strong, fast-acting and long-lasting analgesic effect with no side-effects, it could elevate the lowered plasma LEK level in cervical spondylitis patients and increase plasma SP level. The analgesic mechanism of BTX might be associated with its effect on LEK, SP or other endorphins, directly acting on the pain modulation system.

To retrospectively investigate the clinical effect of the rivet-assisted hollow screw in the treatment of posterior cruciate ligament avulsion fracture. Total 49 patients with knee cruciate ligament avulsion fracture in the ending point of the ligament from January 2010 to December 2014 were divided into the treatment group and the control group. Thirty-one patients in treatment group were treated with rivet-assisted double cannulate nail, including 13 males and 18 females, ranging in age from 38 to 51 years old, with a mean of (40.6±5.1) years old; according to Meyers classification, 23 cases of type 2, 8 cases of type 3; 5 patients were caused by the low energy injury and 26 patients were caused by the high energy injury. Eighteen patients in control group were treated with double gold hollow screw fixation, including 5 males and 13 females, ranging in age from 36 to 52 years old, with an average age of (4.16±4.7) years old; according to Meyers classification, 14 cases of type 2 and 4 cases of type 3;2 patients were caused by the low energy injury and 16 patients were caused by the high energy injury. The operation time, postoperative complications, fracture healing time and the last AKS scoring system were compared between the two groups. All the patients were followed up, and the duration ranged from 12 to 24 months, with an average of 14.2 months. The patients in treatment group had no displacement of fracture fragments and internal fixation failure. The results of AKS score:pain was 48.1±1.5, activity was 21.3±2.7, stability was 20.9±2.5, walking ability was 47.3±1.9, under the stairs ability was 43.4±2.1, the total score was 190.7±2.9. There were 2 cases in control group had fracture fragment displacement and 1 patient had nail withdraw. The results of AKS score:pain was 40.1±2.2, activity was 20.1±0.2, stability was 18.1±3.2, walking ability was 46.3±1.7, under the stairs ability was 40.2 ±1.3, the total score was 180.2±1.4. Therefore, the comparison of the above indicators, the results of the treatment group were better than those of the control group. Rivet-assisted hollow screw fixation in the treatment of cruciate ligament avulsion fracture in the ending, has some advantages such as follows:accurate reduction, less postoperative complications and better postoperative knee function recovery, therefore it is an effective way to treat posterior cruciate ligament avulsion fracture.

Plasmodium knowlesi has long been present in Malaysia, and is now an emerging cause of zoonotic human malaria. Cases have been confirmed throughout South-East Asia where the ranges of its natural macaque hosts and Anopheles leucosphyrus group vectors overlap. The majority of cases are from Eastern Malaysia, with increasing total public health notifications despite a concurrent reduction in Plasmodium falciparum and P. vivax malaria. The public health implications are concerning given P. knowlesi has the highest risk of severe and fatal disease of all Plasmodium spp in Malaysia. Current patterns of risk and disease vary based on vector type and competence, with individual exposure risks related to forest and forest-edge activities still poorly defined. Clustering of cases has not yet been systematically evaluated despite reports of peri-domestic transmission and known vector competence for human-to-human transmission. A population-based case-control study will be conducted over a 2-year period at two adjacent districts in north-west Sabah, Malaysia. Confirmed malaria cases presenting to the district hospital sites meeting relevant inclusion criteria will be requested to enrol. Three community controls matched to the same village as the case will be selected randomly. Study procedures will include blood sampling and administration of household and individual questionnaires to evaluate potential exposure risks associated with acquisition of P. knowlesi malaria. Secondary outcomes will include differences in exposure variables between P. knowlesi and other Plasmodium spp, risk of severe P. knowlesi malaria, and evaluation of P. knowlesi case clustering. Primary analysis will be per protocol, with adjusted ORs for exposure risks between cases and controls calculated using conditional multiple logistic regression models. This study has been approved by the human research ethics committees of Malaysia, the Menzies School of Health Research, Australia, and the London School of Hygiene and Tropical Medicine, UK.

Exhaled breath temperature (EBT) has been suggested as a non-invasive surrogate marker of airway inflammation in asthma. The aim of the study was to evaluate differences in EBT between periods of controlled disease and during exacerbations in children with virus-induced asthma. Twenty-nine children (aged 6-14 years) with a history of intermittent, virus-induced asthma were included in this case-control study. Cases presented with a common cold and/or mild exacerbation of asthma, while controls were free of asthmatic or common cold symptoms during the previous 6 weeks. A baseline questionnaire was obtained. Atopy assessment, central temperature and a spirometric measurement were recorded. EBT was measured with a new device (Delmedica, Singapore). A nasal wash (for identification of common respiratory viruses) was obtained. Twenty-four children (12 from each group) completed the study. Groups were homogeneous with respect to baseline characteristics. PCR revealed the presence of a virus in 3 out of 17 controls and 10 out of 12 cases (17.6 and 83.3%, respectively, p = 0.002). The most commonly identified virus was rhinovirus (3/3 controls and 7/10 cases, p = 0.02). EBT values were significantly higher for cases (34.91 +/- 0.62 degrees C) compared to controls (34.18 +/- 1.1 degrees C, p = 0.032). No important differences were observed in the increase rate of EBT (Deltae degrees T) between groups. Changes in airway inflammation during virus-induced asthma exacerbations are reflected in EBT changes. These preliminary data suggest a possible role of EBT measurements in the assessment of airway inflammation in children with virus-induced asthma. Copyright (c) 2010 S. Karger AG, Basel.
