Uncomplicated diverticular disease is a common condition in patients older than 50 years. Symptoms are aspecific and overlapping with those of irritable bowel syndrome. Nowadays, patients are often treated with antinflammatory drugs (5-aminosalicilic acid). Our purpose was to evaluate the presence of inflammation in the colonic mucosa of patients with symptomatic uncomplicated diverticular disease compared with subjects without diverticula. Endoscopic biopsies of colon from 10 patients with symptomatic uncomplicated diverticular disease and 10 from subjects without diverticula (controls) were taken. Specimens were homogenised and IL2, IL4, IL5, IL8, IL10, IL12p70, IL13, IFN gamma, TNF alfa (searchlight multiplex technique), TGF beta, transglutaminase type 2 and caspase 9 were measured. Histochemistry for transglutaminase type 2 and TUNEL were performed on the histological sections, in addition to morphologic evaluation, as markers of tissue remodelling and apoptosis. For statistical analysis Student's t test and Spearman correlation test were used. No histological differences were detected between the patients with an uncomplicated diverticular disease and controls. Mean values of mucosal cytokines and of the other tested parameters did not show statistically significant differences between patients with uncomplicated diverticular disease and controls. Even if based on a small number of patients, the study demonstrates the absence of inflammation in the mucosa of subjects affected by uncomplicated diverticular disease.

Cochlear pathology in chronic suppurative otitis media.

PubMed

Walby, A P; Barrera, A; Schuknecht, H F

1983-01-01

Chronic suppurative otitis media (COM) is reported to cause elevation of bone-conduction thresholds either by damage to cochlear sensorineural structures or by alteration in the mechanics of sound transmission in the ear. A retrospective study was made of the medical records of 87 patients with unilateral uncomplicated COM to document that abnormality in bone conduction does exist. In a separate study the cochlear pathology in 12 pairs of temporal bones with unilateral COM was studied by light microscopy. Infected ears showed higher than normal mean bone-conduction thresholds by amounts ranging from 1 dB at 500 Hz to 9.5 dB at 4,000 Hz. The temporal bones showed no greater loss of specialized sensorineural structures in infected ears than in normal control ears. Because there is no evidence that COM caused destruction of hair cells or cochlear neurons, alteration in the mechanics of sound transmission becomes a more plausible explanation for the hearing losses.

We aimed to estimate the optimal time of delivery and investigated the residual risk of fetal death after viability in otherwise uncomplicated monochorionic diamniotic twin pregnancies. A database of 576 completed multiple pregnancies that were managed in our tertiary referral fetal medicine department between 1996 and 2007 was reviewed and the uncomplicated 111 monochorionic and the 290 dichorionic diamniotic twin pregnancies delivered after 24 weeks were selected. The rate of fetal death was derived for two-week periods starting at 24 weeks' gestation and the prospective risk of fetal death was calculated by determining the number of intrauterine fetal deaths that occurred within the two-week block divided by the number of continuing uncomplicated monochorionic twin pregnancies during that same time period. The unexpected single intrauterine deaths rate was 2.7% versus 2.8% in previously uncomplicated monochorionic and dichorionic diamniotic pregnancies, respectively. The prospective risk of unexpected stillbirth after 32 weeks of gestation was 1.3% for monochorionic and 0.8% for dichorionic pregnancies. In otherwise apparently uncomplicated monochorionic diamniotic pregnancies this prospective risk of fetal death after 32 weeks of gestation is lower than reported and similar to that of dichorionic pregnancies, so does not sustain the theory of elective preterm delivery.

We conducted a systematic review and meta-analysis of ceftriaxone for treatment of uncomplicated gonorrhoea compared with four other antibiotics. Thirteen randomized controlled trials (RCTs) totalling treatment of 2557 patients with uncomplicated gonorrhoea were included. Statistically significant differences were observed in side-effects, which were increased after ceftriaxone 250 mg versus cefotaxime 500 mg (odds ratio [OR] 1.87; 95% confidence interval [CI] 1.14-3.08). Cure rates of ceftriaxone 250 mg were significantly better than cefixime 400 mg (OR 1.77; 95% CI 1.11-2.80) as was ceftriaxone 125 mg versus spectinomycin 2 g (OR 3.44; 95% CI 1.08-10.90). There was no statistically significant difference between ceftriaxone 250 mg and cefixime 800 mg in cure rates (OR 1.39; 95% CI 0.92-2.10) or adverse effects (OR 1.29, 95% CI 0.58-2.84) for treating uncomplicated gonorrhoea. The cure rate after ceftriaxone 250 mg was not significantly different from that after spectinomycin 2 g (OR 1.96; 95% CI 1.00-3.87). In conclusion, this meta-analysis revealed that 250 mg ceftriaxone had a higher efficacy than 400 mg cefixime for uncomplicated gonorrhoea. Also, ceftriaxone 125 mg is a better choice than spectinomycin 2 g for patients with uncomplicated gonorrhoea, but ceftriaxone had higher side-effect rates than cefotaxime. In the current era further randomized controlled clinical trials of ceftriaxone for uncomplicated gonorrhoea are warranted.

Urinary tract infections (UTI) belong to the most frequent bacterial infections in outpatients. Increasing antibiotic resistance rates and a new appreciation of the epidemiological side effects of antibiotics ("collateral damage") have warranted an update of the guidelines on uncomplicated UTI as an S3 clinical guideline. The guideline was developed by the Deutsche Gesellschaft für Urologie (DGU) in collaboration with the Deutsche Gesellschaft für Allgemein- und Familienmedizin (DEGAM), Deutsche Gesellschaft für Gynäkologie und Geburtshilfe (DGGG), Deutsche Gesellschaft für Hygiene und Mikrobiologie (DGHM), Deutsche Gesellschaft für Infektiologie (DGI), Deutsche Gesellschaft für Nephrologie (DGfN), Paul-Ehrlich-Gesellschaft für Chemotherapie (PEG) and a patient representative. The systematic review of the literature on the topics of the guideline was performed for the time period of 1 January 1998 to 30 April 2008 in the databases of the Cochrane Library and MEDLINE. International guidelines of the years 1999-2007 were included. Uncomplicated UTI comprise uncomplicated cystitis and uncomplicated pyelonephritis. The leading uropathogen is Escherichia coli. The choice of the antibiotic substance follows the five primary aspects: (1) individual patient risk and antibiotic pretreatment; (2) bacterial spectrum and antibiotic susceptibility; (3) effectivity of the antimicrobial substance demonstrated in clinical studies; (4) epidemiological effects ("collateral damage"); and (5) adverse effects. If antibiotics such as trimethoprim/sulfamethoxazole or fluoroquinolones have previously been given, the risk for pathogens to become resistant against these substances is increased. Because of increasing resistance rates of E. coli against trimethoprim/sulfamethoxazole also in uncomplicated UTI, trimethoprim alone or in combination with sulfamethoxazole is no longer regarded as the first-line agent in the empiric treatment of uncomplicated cystitis, unless the regional resistance rate is below 20%. The antibiotic resistance rates of fluoroquinolones in uncomplicated UTI are still below 10% in Germany, but there is a significant emergence of resistance compared to earlier years. Moreover, fluoroquinolones and group 3 cephalosporins exhibit negative epidemiological effects resulting in selection of multi-resistant pathogens. Because these antibiotic classes are needed in therapy of life-threatening infections, such effects should be taken seriously. For substances like fosfomycin, nitrofurantoin or mecillinam"collateral damage" has not been documented or only to a lesser degree. Therefore, for empiric therapy of frequent uncomplicated cystitis fosfomycin-trometamol, nitrofurantoin or pivmecillinam (not listed in Germany) are recommended as first-line antibiotics. For oral first-line treatment of uncomplicated pyelonephritis, fluoroquinolones are still recommended in sufficiently high dosage due to the resistance rates of E. coli still being below 10% and the superior effectivity compared to other antibiotics. Asymptomatic bacteriuria (ASB) should only be treated in exceptional cases such as pregnant women or prior to expected mucocutaneous traumatising interventions of the urinary tract. The S3 guideline on uncomplicated urinary tract infections is a comprehensive set of evidence- and consensus-based recommendations dealing with epidemiology, diagnosis, therapy and management of uncomplicated bacterial UTI of adult outpatients. A broad implementation in all disciplines taking care of patients with UTI is necessary in order to ensure a prudent antibiotic policy in these frequent infections and thus improve patient care.

Objective The objective of the study was to determine whether blood pressure increases are associated with maternal angiogenic factors in uncomplicated and preeclamptic pregnancies. Study Design Associations of blood pressure increases from mid- to late pregnancy with maternal serum concentrations of soluble fms-like tyrosine kinase receptor (sFlt1), soluble endoglin (sEng), and placental growth factor (PlGF) at delivery were analyzed in 43 uncomplicated and 44 preeclamptic pregnancies. Results In uncomplicated pregnancies, increases in diastolic and mean arterial pressure were inversely associated with PlGF at delivery and positively associated with sEng and sFlt1/PlGF ratio. There were no significant associations between blood pressure increases and angiogenic factor concentrations in preeclampsia. Conclusion These data suggest that angiogenic factors are involved in blood pressure modulation in normotensive pregnancy and are consistent with the hypothesis that angiogenic balance plays a role in maternal breast cancer risk reduction associated with mid- to late blood pressure increases in uncomplicated pregnancies.

Although computed tomography (CT) is the imaging modality of choice for diagnosing colonic diverticulitis today, there remains a risk of colorectal cancer mimicking diverticulitis due to overlapping imaging features. Current practice guidelines recommend interval colonoscopy after diverticulitis to exclude occult malignancy. Some authors have suggested that this may be unnecessary in patients with uncomplicated diverticulitis. The aim of our study was to examine the prevalence of occult colorectal cancer in patients with CT-proven acute uncomplicated diverticulitis in an Asian population. This was a retrospective study of all patients admitted for CT-proven acute uncomplicated diverticulitis between 2007 and 2011 in a single institution. Colonoscopy and histopathology reports were reviewed for patients who underwent interval colonic evaluation. For patients who defaulted follow-up, national health records were reviewed for any subsequent diagnoses of colorectal cancer. The primary outcome was prevalence of colorectal cancer in the cohort. Secondary outcome was prevalence of advanced adenomas. A total of 227 patients with acute uncomplicated diverticulitis were included in our study. One hundred and thirty-five patients (59.5%) underwent follow-up colonic evaluation. The overall prevalence of colorectal cancer was 1.8%, with half these patients presenting with acute colonic obstruction after defaulting follow-up evaluation. Of the patients, 1.5% who underwent colonoscopy had advanced adenomas. Prevalence of colorectal cancer in patients with CT-proven acute uncomplicated diverticulitis may not be as low as previously suggested. We recommend that patients with acute uncomplicated diverticulitis continue to be offered interval colonoscopy until larger studies demonstrate the safety of omission.

To obtain information on prescribing rates and choice of antibiotics for acute, uncomplicated respiratory tract infections (RTIs) in the community. Antibiotic use in acute, uncomplicated RTIs consisting of common cold/sore throat/cough for not more than five days was surveyed in the community (December 2007-November 2008) using patient exit interviews at public and private facilities from four localities in New Delhi. Data were collected from 10 public sector facilities and 20 private clinics over one year. The percentage of acute, uncomplicated RTIs patients receiving antibiotics in general and using the Anatomical Therapeutic Chemical classification and the Defined Daily Dose (ATS/DDD) were analysed. At public and private facilities, 45% (746/1646) and 57% (259/457) of acute, uncomplicated RTI patients were prescribed at least one antibiotic, respectively. The main antibiotic class calculated as percentage of total antibiotics DDDs/1000 prescribed to acute, uncomplicated RTI patients at private clinics was cephalosporins, J01DA (39%), followed by fluoroquinolones, J01MA (24%), penicillins, J01C (19%) and macrolides, J01FA (15%). Newer members from each class were prescribed; older antibiotics such as co-trimoxazole or tetracyclines were rarely prescribed. At public facilities, the main class of antibiotic prescribed was penicillins (31%), followed by macrolides (25%), fluoroquinolones (20%) and cephalosporins (10%). Study clearly shows overuse and inappropriate choice of antibiotics for the treatment of acute, uncomplicated RTIs which are mainly due to virus and do not require antibiotic treatment. Results of the study warrant interventional strategies to promote rational use of antibiotics to decrease the overgrowing threat of antibiotic resistance. © 2014 John Wiley & Sons Ltd.

To investigate the proportion of malaria infection in febrile children consulting a paediatric hospital in Brazzaville, to determine the prevalence of submicroscopic malaria infection, to characterise Plasmodium falciparum infection and compare the prevalence of uncomplicated P. falciparum malaria according to haemoglobin profiles. Blood samples were collected from children aged <10 years with an axillary temperature ≥37.5 °C consulting the paediatric ward of Marien Ngouabi Hospital in Brazzaville. Parasite density was determined and all samples were screened for P. falciparum by nested polymerase chain reaction (PCR) using the P. falciparum msp-2 marker to detect submicroscopic infections and characterise P. falciparum infection. Sickle cell trait was screened by PCR. A total of 229 children with fever were recruited, of whom 10% were diagnosed with uncomplicated malaria and 21% with submicroscopic infection. The mean parasite density in children with uncomplicated malaria was 42 824 parasites/μl of blood. The multiplicity of infection (MOI) was 1.59 in children with uncomplicated malaria and 1.69 in children with submicroscopic infection. The mean haemoglobin level was 10.1 ± 1.7 for children with uncomplicated malaria and 12.0 ± 8.6 for children with submicroscopic infection. About 13% of the children harboured the sickle cell trait (HbAS); the rest had normal haemoglobin (HbAA). No difference in prevalence of uncomplicated malaria and submicroscopic infection, parasite density, haemoglobin level, MOI and P. falciparum genetic diversity was observed according to haemoglobin type. The low prevalence of uncomplicated malaria in febrile Congolese children indicates the necessity to investigate carefully other causes of fever. © 2016 John Wiley & Sons Ltd.

Urinary tract infection in children is well recognized as a cause of acute morbidity and chronic medical conditions. As a result, appropriate use of antimicrobial agents, however, increases antibiotic resistance and complicates its treatment due to increased patient morbidity, costs, rates of hospitalization, and use of broader-spectrum antibiotics. The goal of this study was to determine antibiotic susceptibility to commonly used agents for urinary tract infection against recent urinary isolates. A total of 457 consecutive children attending the emergency room at the Hospital Infantil de México Federico Gómez with symptoms of uncomplicated lower urinary tract infection were eligible for inclusion. Patients who had had symptoms for≥7 days and those who had had previous episodes of urinary tract infection, received antibiotics or other complicated factors were excluded. Midstream and catheter urine specimens were collected. All isolates were identified and the in vitro activities of antimicrobials were determined. The most frequently isolated urinary pathogens were as follows: Escherichia coli (E. coli) (312, 68.3%), Enterococcus spp. (42, 11%), Klebsiella pneumoniae (K. pneumoniae) (40, 8.7%), Pseudomonas aeruginosa (P. aeruginosa) (34, 7.5%), Proteus mirabilis (P. mirabilis) (21, 4.5%), Enterobacter cloacae (8, 1.7%). The resistance to trimetoprim/sulfametoxazol (%) was 73.7, 62.2, 100, 52, and 50, respectively, for E. coli, K. pneumoniae, P. aeruginosa, P. mirabilis and Enterobacter spp., 92.5 for Enterococcus faecalis (E. faecalis) and 49.9 for Enterococcus faecium (E. faecium). Ampicillin was 86.3, 45, 100, 47.9, and 66.6% for the same strains, ciprofloxacin 33.8, 9, 18.8, 0, 0%, nitrofurantoin 4.4, 13, 97.7, 70, 0%; to E. faecalis 0% and 16.7% to E. faecium. Frequently prescribed empirical agents for uncomplicated urinary tract infection demonstrate lowered in vitro susceptibilities when tested against recent clinical isolates.

Optimizing the care model for an uncomplicated acute pain episode in sickle cell disease.

PubMed

Telfer, Paul; Kaya, Banu

2017-12-08

The pathophysiology, clinical presentation, and natural history of acute pain in sickle cell disease are unique and require a disease-centered approach that also applies general principles of acute and chronic pain management. The majority of acute pain episodes are managed at home without the need to access health care. The long-term consequences of poorly treated acute pain include chronic pain, adverse effects of chronic opioid usage, psychological maladjustment, poor quality of life, and excessive health care utilization. There is no standard protocol for management of an acute pain crisis in either the hospital or the community. The assumptions that severe acute pain must be managed in the hospital with parenteral opioids and that strong opioids are needed for home management of pain need to be questioned. Pain management in the emergency department often does not meet acceptable standards, while chronic use of strong opioids is likely to result in opioid-induced hyperalgesia, exacerbation of chronic pain symptoms, and opioid dependency. We suggest that an integrated approach is needed to control the underlying condition, modify psychological responses, optimize social support, and ensure that health care services provide safe, effective, and prompt treatment of acute pain and appropriate management of chronic pain. This integrated approach should begin at an early age and continue through the adolescent, transition, and adult phases of the care model. © 2016 by The American Society of Hematology.

Medical Treatment of Diverticular Disease: Antibiotics.

PubMed

Lué, Alberto; Laredo, Viviana; Lanas, Angel

2016-10-01

Diverticular disease (DD) of the colon represents the most common disease affecting the large bowel in western countries. Its prevalence is increasing. Recent studies suggest that changes in gut microbiota could contribute to development of symptoms and complication. For this reason antibiotics play a key role in the management of both uncomplicated and complicated DD. Rifaximin has demonstrated to be effective in obtaining symptoms relief at 1 year in patients with uncomplicated DD and to improve symptoms and maintain periods of remission following acute colonic diverticulitis (AD). Despite absence of data that supports the routine use of antibiotic in uncomplicated AD, they are recommended in selected patients. In patients with AD that develop an abscess, conservative treatment with broad-spectrum antibiotics is successful in up to 70% of cases. In patients on conservative treatment where percutaneous drainage fails or peritonitis develops, surgery is considered the standard therapy. In conclusion antibiotics seem to remain the mainstay of treatment in symptomatic uncomplicated DD and AD. Inpatient management and intravenous antibiotics are necessary in complicated AD, while outpatient management is considered the best strategy in the majority of uncomplicated patients.

Many data coming from animal models and clinical observations support an involvement of intestinal microbiota in the pathogenesis of Crohn's disease (CD). It is hypothesized in fact, that the development of chronic intestinal inflammation is caused by an abnormal immune response to normal flora in genetically susceptible hosts. The involvement of bacteria in CD inflammation has provided the rationale for including antibiotics in the therapeutic armamentarium. However, randomized controlled trials have failed to demonstrate an efficacy of these drugs in patients with active uncomplicated CD, even if a subgroup of patients with colonic location seems to get benefit from antibiotics. Nitroimidazole compounds have been shown to be efficacious in decreasing CD recurrence rates in operated patients, and the use of metronidazole and ciprofloxacin is recommended in perianal disease. However, the appearance of systemic side effects limits antibiotic long-term employment necessary for treating a chronic relapsing disease. Rifaximin, characterized by an excellent safety profile, has provided promising results in inducing remission of CD.

to explore women's preferences with regard to their preferred health professional during labour and childbirth in case of an uncomplicated pregnancy, and to gain insight into women's knowledge of the legal competences of midwives. a descriptive observational study. Brussels metropolitan region, Belgium. women in their reproductive age, living in the Brussels metropolitan region, with Dutch or French as their first language (n=830). a ten-item standardized questionnaire'Midwife Profiling Questionnaire' (MidProQ) was developed to determine which health professional respondents would prefer to assist them during labour and childbirth if there were no complications and to assess their knowledge about midwives' legal competences during pregnancy, labour and childbirth. Descriptive statistics were used to report the findings. To identify relationships between the socio-demographic variables of the women and her preferences, knowledge and opinion Chi² analysis were used. For 68.0% of the participants in an uncomplicated labour (n=564) and 66.3% of the participants with an uncomplicated childbirth (n=550), a midwife is the preferred health professional. Brussels women prefer an obstetrician in an uncomplicated labour (n=730, 88%) and for uncomplicated childbirth (n=756, 91.1%). Only 20.2% of the respondents (n=168) consider midwives to play a central role in an uncomplicated pregnancy. The knowledge of Brussels women about midwives' legal competences during pregnancy, labour and childbirth is rather poor, especially in youngsters and women who have never given birth. In general, for Brussels women, midwives are not the first preferred health professional for an uncomplicated labour or for childbirth, and they do not consider midwives to play a central role in an uncomplicated pregnancy. The legal competences of midwives are not known very well, especially by youngsters and women who have never given birth. The Belgian medical model of maternity care and women's experiences affect their preferences and knowledge about the legal competences of midwives and their opinion about the central health professional in an uncomplicated pregnancy. To enhance more women-centred care and initiate change in the current maternity care culture in Belgium, public education, structural changes in maternity services and strategies to inspire public opinion to initiate cultural change are suggested. Involvement of midwifery organisations, other health professionals in maternity services and policy-makers with women's groups and potential service users is key. Copyright © 2016 Elsevier Ltd.

AIM: To design a medical cost calculator and show that diabetes care is beyond reach of the majority particularly patients with complications. METHODS: Out-of-pocket expenditures of patients for medical treatment of type-2 diabetes were estimated based on price data collected in Benin, Burkina Faso, Guinea and Mali. A detailed protocol for realistic medical care of diabetes and its complications in the African context was defined. Care components were based on existing guidelines, published data and clinical experience. Prices were obtained in public and private health facilities. The cost calculator used Excel. The cost for basic management of uncomplicated diabetes was calculated per person and per year. Incremental costs were also computed per annum for chronic complications and per episode for acute complications. RESULTS: Wide variations of estimated care costs were observed among countries and between the public and private healthcare system. The minimum estimated cost for the treatment of uncomplicated diabetes (in the public sector) would amount to 21%-34% of the country’s gross national income per capita, 26%-47% in the presence of retinopathy, and above 70% for nephropathy, the most expensive complication. CONCLUSION: The study provided objective evidence for the exorbitant medical cost of diabetes considering that no medical insurance is available in the study countries. Although the calculator only estimates the cost of inaction, it is innovative and of interest for several stakeholders. PMID:26617974

Contact lens wear is intrinsically inflammatory.

PubMed

Efron, Nathan

2017-01-01

Eye-care practitioners typically associate ocular inflammation during contact lens wear with serious complications such as microbial keratitis; however, more subtle mechanisms may be at play. This paper tests the notion that contact lens wear is intrinsically inflammatory by exploring whether uncomplicated contact lens wear meets the classical, clinical definition of inflammation - rubor (redness), calor (heat), tumor (swelling), dolor (pain) and functio laesa (loss of function) - as well as the contemporary, sub-clinical definition of inflammation (cellular and biochemical reactions). It is demonstrated that all of these clinical and sub-clinical criteria are met with hydrogel lens wear and most are met with silicone hydrogel lens wear, indicating that uncomplicated contact lens wear is intrinsically inflammatory. Consideration of both traditional and contemporary thinking about the role of inflammation in the human body leads to the perhaps surprising conclusion that the chronic, low grade, sub-clinical inflammatory status of the anterior eye during contact lens wear, which may be termed 'para-inflammation', is a positive, protective phenomenon, whereby up-regulation of the immune system, in a non-damaging way, maintains the eye in a state of 'heightened alert', ready to ward off any extrinsic noxious challenge. Characterisation of this inflammatory status may lead to the development of lens engineering or pharmacological strategies to modulate contact lens-induced inflammation, so as to render lens wear more safe and comfortable. © 2016 Optometry Australia.

To correlate clinical manifestations with choroidal morphology in pachychoroid disorders, including central serous chorioretinopathy, pachychoroid pigment epitheliopathy, pachychoroid neovasculopathy, and polypoidal choroidal vasculopathy, using en face swept-source optical coherence tomography (OCT). Patients with pachychoroid spectrum diagnoses were identified nonconsecutively through a review of charts and multimodal imaging. Each eye was categorized as uncomplicated pachychoroid, pachychoroid pigment epitheliopathy, central serous chorioretinopathy, pachychoroid neovasculopathy, or polypoidal choroidal vasculopathy. All patients included in this series then underwent bilateral swept-source OCT. Sixty-six eyes of 33 patients were included. Numbers assigned to diagnostic categories were 8 uncomplicated pachychoroid, 13 pachychoroid pigment epitheliopathy, 27 central serous chorioretinopathy, 15 pachychoroid neovasculopathy, and 3 polypoidal choroidal vasculopathy. One eye was classified as normal. Swept-source OCT choroidal thickness maps confirmed increased thickness under the areas of pachychoroid pigment epitheliopathy, central serous chorioretinopathy, type 1 NV (pachychoroid neovasculopathy), or polyps (polypoidal choroidal vasculopathy). En face swept-source OCT showed dilated outer choroidal vessels in all eyes. In several eyes with a chronic disease, focal choriocapillaris atrophy with inward displacement of deep choroidal vessels was noted. Although clinical manifestations of pachychoroid spectrum disorders vary considerably, these entities share morphologic findings in the choroid, including increased thickness and dilated outer choroidal vessels. En face swept-source OCT localizes these changes to disease foci and shows additional findings that may unify our understanding of disease pathogenesis.

To examine the relative incidence of newly recorded diagnosis of depression after spinal surgery as a proxy for the risk of post-spinal surgery depression. We used the longitudinal California Office of Statewide Health Planning and Development database (January 1, 2000, through December 31, 2010) to identify patients who underwent spinal surgery during these years. Patients with documented depression before surgery were excluded. Risk of new postoperative depression was determined via the incidence of newly recorded depression on any hospitalization subsequent to surgery. For comparison, this risk was also determined for patients hospitalized during the same time period for coronary artery bypass grafting, hysterectomy, cholecystectomy, chronic obstructive pulmonary disease, congestive heart failure exacerbation, or uncomplicated vaginal delivery. Our review identified 1,078,639 patients. Relative to the uncomplicated vaginal delivery cohort, the adjusted hazard ratios (HRs) for newly recorded depression within 5 years after the admission of interest were 5.05 for spinal surgery (95% CI, 4.79-5.33), 2.33 for coronary artery bypass grafting (95% CI, 2.15-2.54), 3.04 for hysterectomy (95% CI, 2.88-3.21), 2.51 for cholecystectomy (95% CI, 2.35-2.69), 2.44 for congestive heart failure exacerbation (95% CI, 2.28-2.61), and 3.04 for chronic obstructive pulmonary disease (95% CI, 2.83-3.26). Among patients who underwent spinal surgery, this risk of postoperative depression was highest for patients who underwent fusion surgery (HR, 1.28; 95% CI, 1.22-1.36) or had undergone multiple spinal operations (HR, 1.22; 95% CI, 1.16-1.29) during the analyzed period. Patients who undergo spinal surgery have a higher risk for postoperative depression than patients treated for other surgical or medical conditions known to be associated with depression.

Chloroquine (CQ) is officially used for the primary treatment of Plasmodium falciparum malaria in Honduras. In this study, the therapeutic efficacy of CQ for the treatment of uncomplicated P. falciparum malaria in the municipality of Puerto Lempira, Gracias a Dios, Honduras was evaluated using the Pan American Health Organization-World Health Organization protocol with a follow-up of 28 days. Sixty-eight patients from 6 months to 60 years of age microscopically diagnosed with uncomplicated P. falciparum malaria were included in the final analysis. All patients who were treated with CQ (25 mg/kg over 3 days) cleared parasitemia by day 3 and acquired no new P. falciparum infection within 28 days of follow-up. All the parasite samples sequenced for CQ resistance mutations (pfcrt) showed only the CQ-sensitive genotype (CVMNK). This finding shows that CQ remains highly efficacious for the treatment of uncomplicated P. falciparum malaria in Gracias a Dios, Honduras.

Uncomplicated bacterial community-acquired urinary tract infection is among the more common infections in outpatient practice. The resistance level of pathogens has risen markedly. This S3 guideline contains recommendations based on current evidence for the rational use of anti - microbial agents and for the prevention of inappropriate use of certain classes of antibiotics and thus of the resulting drug resistance. The prevention of recurrent urinary tract infection is considered in this guideline for the first time. The guideline was updated under the aegis of the German Urological Society (Deutsche Gesellschaft für Urologie). A systematic literature search (period: 2008-2015) concerning the diagnosis, treatment, and prevention of uncomplicated urinary tract infections was carried out in the Cochrane Library, MEDLINE, and Embase databases. Randomized, controlled trials and systemic reviews were included. Relevant guidelines were identified in a guideline synopsis. Symptom-oriented diagnostic evaluation is highly valued. For the treatment of cystitis, fosfomycin-trometamol, nitrofurantoin, nitroxolin, pivmecillinam and trimethoprim are all equally recommended. Fluorquinolones and cephalosporins are not recommended. Uncomplicated pyelonephritis with a mild to moderate clinical course ought to be treated with oral cefpodoxime, ceftibuten, ciprofloxacin, or levofloxacin. For acute, uncomplicated cystitis, with mild to moderate symptoms, symptomatic treatment alone may be considered instead of antibiotics after discussion of the options with the patient. Mainly non-antibiotic measures are recommended for prophylaxis against recurrent urinary tract infection. Physicians who treat uncomplicated urinary tract infections should familiarize themselves with the newly revised guideline's recommendations on the selection and dosage of antibiotic treatment so that they can responsibly evaluate and plan antibiotic treatment for their affected patients.

[Nitrofurantoin--clinical relevance in uncomplicated urinary tract infections].

PubMed

Stock, Ingo

2014-07-01

The nitrofuran derivative nitrofurantoin has been used for more than 60 years for the antibacterial therapy of uncomplicated urinary tract infections (UTI). Despite its long application, this antibiotic retained good activity against Escherichia coli and some other pathogens of uncomplicated urinary tract infections such as Staphylococcus saprophyticus and Enterococcus species. Nitrofurantoin therapy has been shown to be accompanied by numerous adverse drug effects. Among these, there are also serious side effects such as pulmonary reactions and polyneuropathy, which mainly occur in long-term use. Recent studies, however, have shown a good efficacy and tolerability of short-term nitrofurantoin therapy comparable to previous established standard therapeutic regimens applying cotrimoxazole or quinolones. Because of these data and the alarming resistance rates of uropathogenic Escherichia coli to cotrimoxazole and quinolones that have been increased markedly in several countries, the clinical significance ofnitrofurantoin has been raised again. In many current treatment guidelines, e. g., the international clinical practice guidelines for the treatment of acute uncomplicated cystitis and pyelonephritis in women published by the Infectious Diseases Society of America and the European Society for Microbiology and Infectious Diseases, nitrofurantoin has been recommended as one first-line antibiotic of empiric antibacterial treatment of uncomplicated cystitis in otherwise healthy women. In Germany, however, nitrofurantoin should only be applied if more effective and less risky antibiotics cannot be used. Nitrofurantoin is contraindicated in the last three months of pregnancy and in patients suffering from renal impairment of each degree. Despite compatibility concerns, nitrofurantoin has also been recommended for the re-infection prophylaxis of recurrent uncomplicated urinary tract infections in Germany and several other countries.

Current studies suggest that the control of Diabetes mellitus can be improved with home monitoring of blood sugars. Voice synthesizers and recent technology, allowing decoding of Touch-Tone® pulses into their digital equivalents, make it possible for diabetics with no more sophisticated equipment than a Touch-Tone® telephone to enter their blood sugars directly into a medical office computer. A working prototype that can provide physicians with timely, logically oriented information about their diabetics is discussed along with plans to expand this concept into giving the patients uncomplicated therapeutic advice without the need for a direct patient/physician interaction. The potential impact on health care costs and the management of other chronic diseases is presented.

To evaluate the outcome and the costs of stenting in uncomplicated semirigid ureteroscopic stone removal. A decision tree model was created to evaluate the economic impact of routine stenting versus non-stenting strategies in uncomplicated ureteroscopy (URS). Probabilities of complications were extracted from twelve randomized controlled trials. Stone removal costs, costs for complication management, and total costs were calculated using Treeage Pro (TreeAge Pro Healthcare version 2015, Software, Inc, Williamstown Massachusetts, USA). Stone removal costs were higher in stented URS (€1512.25 vs. €1681.21, respectively). Complication management costs were higher in non-stented procedures. Both for complications treated conservatively (€189.43 vs. €109.67) and surgically (€49.26 vs. €24.83). When stone removal costs, costs for stent removal, and costs for complication management were considered, uncomplicated URS with stent placement yielded an overall cost per patient of €1889.15 compared to €1750.94 without stent placement. The incremental costs of stented URS were €138.25 per procedure. Semirigid URS with stent placement leads to higher direct procedural costs. Costs for managing URS-related complications are higher in non-stented procedures. Overall, a standard strategy of deferring routine stenting uncomplicated ureteroscopic stone removal is more cost efficient.

To assess process-of-care indicators and outcomes in acute pyelonephritis (APN) in a general hospital emergency department, and compare them between uncomplicaed and complicated APN. Retrospective study of consecutive patients discharged with a diagnosis of APN. We studied health processof- care indicators (percentage admitted, avoidable hospitalization, appropriate initial antibiotic therapy, urine and blood cultures) and outcomes (hospital length of stay [LOS], discharge from the emergency department, revisits, mortality, yields of microbiological tests ordered). A total of 529 cases (59% of them complicated) were included. Patients with uncomplicated APN were significantly younger on average (mean, 39 years) than patients with complicated APN (56 years). Escherichia coli was the most common pathogen identified, although the percentage of E coli infection was lower in patients with complicated APN (78%) than in patients with uncomplicated APN (95%). The rates of admission and orders for urine and blood cultures were significantly higher and hospital LOS was longer in the group with complicated APN. Moreover, these patients had even longer stays if the initial antibiotic therapy was inappropriate. Significantly more patients with uncomplicated APN were discharged from the emergency department. Sixty-one percent of patients with uncomplicated APN were admitted; 9% of these cases were considered avoidable hospitalizations. Complicated APN is diagnosed more often in older patients, and E coli infection causes a smaller proportion of these cases. Hospital LOS is longer in complicated APN and more urine and blood cultures are ordered. Patients with uncomplicated APN are more often discharged from the emergency department, although the number of avoidable hospitalizations seems high based on the rate found in this study.

Malaria can present itself as an uncomplicated or severe disease. We have here studied the quantity and quality of antibody responses against merozoite antigens, as well as multiplicity of infection (MOI), in children from Uganda. We found higher levels of IgG antibodies toward erythrocyte-binding antigen EBA181, MSP2 of Plasmodium falciparum 3D7 and FC27 (MSP2-3D7/FC27), and apical membrane antigen 1 (AMA1) in patients with uncomplicated malaria by enzyme-linked immunosorbent assay (ELISA) but no differences against EBA140, EBA175, MSP1, and reticulocyte-binding protein homologues Rh2 and Rh4 or for IgM against MSP2-3D7/FC27.Patients with uncomplicated malaria were also shown to have higher antibody affinities for AMA1 by surface plasmon resonance (SPR). Decreased invasion of two clinical P. falciparum isolates in the presence of patient plasma correlated with lower initial parasitemia in the patients, in contrast to comparisons of parasitemia to ELISA values or antibody affinities, which did not show any correlations. Analysis of the heterogeneity of the infections revealed a higher MOI in patients with uncomplicated disease, with the P. falciparum K1 MSP1 (MSP1-K1) and MSP2-3D7 being the most discriminative allelic markers. Higher MOIs also correlated positively with higher antibody levels in several of the ELISAs. In conclusion, certain antibody responses and MOIs were associated with differences between uncomplicated and severe malaria. When different assays were combined, some antibodies, like those against AMA1, seemed particularly discriminative. However, only decreased invasion correlated with initial parasitemia in the patient, signaling the importance of functional assays in understanding development of immunity against malaria and in evaluating vaccine candidates.

This study investigated lifetime prevalence rates, demographic characteristics, childhood conduct disorder and adult antisocial features, suicide attempts, and cognitive impairment in individuals with obsessive-compulsive disorder (OCD) uncomplicated by or comorbid with any other psychiatric disorder. The data are from the NIMH Epidemiologic Catchment Area (ECA) study, and the current analyses compared subjects with uncomplicated OCD (no history of any other lifetime psychiatric disorder), comorbid OCD (with any other lifetime disorder), other lifetime psychiatric disorders, and no lifetime psychiatric disorders across these variables. OCD in its uncomplicated and comorbid form had significantly higher rates of childhood conduct symptoms, adult antisocial personality disorder problems, and of suicide attempts than did no or other disorders. Comorbid OCD subjects had higher rates of mild cognitive impairment on the Mini-Mental Status Exam than did subjects with other disorders. These findings suggest that a subgroup of OCD patients may have impulsive features, including childhood conduct disorder symptoms and an increased rate of suicide attempts; wider clinical attention to these outcomes is needed.

Probiotics and Diverticular Disease: Evidence-based?

PubMed

Lahner, Edith; Annibale, Bruno

Diverticular disease (DD) is a common gastrointestinal condition. Clinical spectrum ranges from asymptomatic diverticulosis to symptomatic uncomplicated or complicated DD. Symptoms related to uncomplicated DD are not specific and may be indistinguishable from those of irritable bowel syndrome. Low-grade inflammation, altered intestinal microbiota, visceral hypersensitivity, and abnormal colonic motility have been identified as factors potentially contributing to symptoms. Probiotics may modify the gut microbial balance leading to health benefits. Probiotics, due to their anti-inflammatory effects and ability to maintain an adequate bacterial colonization in the colon, are promising treatment options for DD. This review focuses on the available evidence on the efficacy of prebiotics in uncomplicated DD.

Protein turnover in atrophying muscle: from nutritional intervention to microarray expression analysis

NASA Technical Reports Server (NTRS)

Stein, T. Peter; Wade, Charles E.

2003-01-01

PURPOSE OF REVIEW: In response to decreased usage, skeletal muscle undergoes adaptive reductive remodeling due to the decrease in tension on the weight bearing components of the musculo-skeletal system. This response occurs with uncomplicated disuse (e.g. bed rest, space flight), as a secondary consequence of several widely prevalent chronic diseases for which activity is reduced (e.g. chronic obstructive pulmonary disease and chronic heart failure) and is part of the aging process. The problem is therefore one of considerable clinical importance. RECENT FINDINGS: The impaired function and exercise intolerance is related more to the associated muscle wasting rather than to the specific organ system primarily impacted by the disease. Progress has continued in describing the use of anabolic drugs and dietary manipulation. The major advance in the field has been: (i) the discovery of the atrogin-1 gene and (ii) the application of microarray expression analysis and proteomics with the objectives of obtaining comprehensive understanding of the pathways changed with disuse atrophy. SUMMARY: Disuse atrophy is a common clinical problem. There is a need for therapeutic interventions that do not involve exercise. A better understanding of the changes, particularly at the molecular level, could indicate hitherto unsuspected sites for nutritional and pharmacological intervention.

Urinary tract infections are one of the most common bacterial infectious diseases in humans. Depending on the localization and the effectiveness of pathogenetic factors, various clinical pictures (lower urinary tract infection, pyelonephritis, asymptomatic bacteriuria) have to be differentiated. There are virulence factors of microorganisms on the one hand and defense mechanisms on the other, which influence the manifestation and the course of disease. The process of bacterial attachment to the epithelial cells of the boundary layer, the internalization and invasion of bacteria could be important for acute and chronic disease. Disturbances of local defense mechanisms, such as increased urinary glucose concentration in diabetes or variations of Tamm-Horsfall protein and defensin levels, may influence the course of infection. On the basis of microbiological and laboratory findings as well as the results of clinical and ultrasound procedures, the decision on the therapeutic strategy should be made. There are different treatment recommendations for acute uncomplicated and complicated cases as well as for chronic diseases. Future investigations should focus on effective therapeutic options for special immunocompromised patients in relation to the microbiological aspects and defense mechanisms of the host.

In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. Themore » close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.« less

Laparoscopic Puestow: lateral pancreaticojejunostomy.

Chronic pancreatitis is a painful inflammatory disease that leads to progressive and irreversible destruction of pancreatic parenchyma [1]. A lateral pancreaticojejunostomy, also known as the Puestow procedure, is performed for symptomatic chronic pancreatitis associated with a dilated pancreatic duct secondary to calcifications or strictures [4]. An open approach is used traditionally due to the complexity of the case, and there have only been a handful of laparoscopic case reports [2]. This video depicts a laparoscopic lateral pancreaticojejunostomy for chronic pancreatitis. A 45-year-old gentleman with a 20-year history of chronic alcohol abuse presented with diffuse abdominal pain. His pain was worse postprandially and associated with loose stools. A computed tomography scan revealed multiple calcified deposits within the body and tail of the pancreas, and a dilated pancreatic duct measuring 1.4 cm with a proximal obstructing calcified stone. A 5-port foregut technique was used, and a 15-cm pancreatic ductotomy was performed with an ultrasonic scalpel. Calcified stones were cleared from the duct, and a roux-en-y pancreaticojejunostomy was performed using a hand-sewn technique. The patient had a relatively uncomplicated hospital course with return of bowel function on postoperative day 4. His patient-controlled analgesic device was discontinued on post operative day 3. He was ambulating, tolerating a regular diet and discharged home on postoperative day 5. At 12- and 26-month follow-up, he remains off narcotics, but still requires 1-2 tabs of pancreatic enzyme replacement per meal. Most importantly, he has not had any alcohol for over 2 years. The two primary goals in treating chronic pancreatitis include long-term pain relief and improvements in quality of life [3]. For patients with chronic pancreatitis and a dilated pancreatic duct, a laparoscopic lateral pancreaticojejunostomy may be an effective approach to decrease pain and improve quality of life.

Uncomplicated urinary tract infections (UTIs) are the most common bacterial infections among women presenting to primary care causing rapidly increasing strains of resistant bacteria to the growing antibiotic industry. Restricting antibiotics to necessary indications is the only solution. The objectives of the study were to compare the efficacy of symptomatic treatment vs antibiotic in patients with uncomplicated UTI, in terms of individual symptom score, i.e., frequency, urgency, dysuria, supra pubic pain scores and total symptoms scores. A randomized control trial (RCT) in 100 women (15-50 years) with symptoms of urinary frequency, urgency, dysuria and pain supra pubic region, associated with uncomplicated UTI, at Urology department, AMI, Abbottabad. Two treatment strategies were compared in uncomplicated UTI patient). Patients were randomized to antibiotic or symptomatic treatment groups on consecutive non-probability basis (50 in each group) given for 05 days. Efficacy of medications was assessed by comparing pre and post treatment symptom scores along with the post treatment scores of both groups compared to see statistical significance of difference by independent samples t-test. There was a statistically significant difference in symptoms improvement in both treatment arms of all scores, i.e., p-value=0.000. Whereas only dysuria score was able to show a statistically significance of difference in post Rx scores comparison of both groups, p-value=0.004. Symptomatic treatment is not inferior to antibiotic treatment when proper patient selection is undertaken, resulting in decreased need for unnecessary antibiotics use.

Chloroquine (CQ) is a relatively inexpensive drug for treatment of malaria. If efficacy of CQ is still assumed, then it should be indicated in malaria treatment policies as the drug of choice for uncomplicated Plasmodium vivax malaria in endemic countries with resource constraints. The objective of this review is to summarize the existing evidence on the relative efficacy and safety of CQ in treating patients with uncomplicated P. vivax malaria in endemic countries. We searched online data bases (PUBMED, MEDLINE, EMBASE, The Cochrane Library) and the reference lists of the retrieved articles. Fifteen randomized controlled trials (n=6215) assessing the relative efficacy and safety of CQ for treatment of uncomplicated P. vivax malaria were included. CQ monotherapy was compared to CQ plus primaquine (PQ), artemisinin/artemether, artemisinin based combination therapy, quinine, CQ plus tafenoquine, chlorguanil plus dapsone, azithromycin, or placebo. Treatment efficacy was not significantly different between the CQ monotherapy group and that of the CQ with PQ 14 day group at 28 day follow-up (55/711, 7.7% vs 35/712, 4.9%; P=0.16). Evidence from the trials identified for this review draw a fairly clear conclusion about the relative efficacy and safety of CQ for treating uncomplicated P. vivax malaria infection. However, further research in this field with well powered, randomized, non-inferiority design, using the standardized protocol is needed.

Although the standard treatment of acute appendicitis (AA) consists of an early appendectomy, there has recently been both an interest and an increase in the use of antibiotic therapy as the primary treatment for uncomplicated AA. However, the use of antibiotic therapy in the treatment of uncomplicated AA is still controversial. The APPAC trial is a randomized prospective controlled, open label, non-inferiority multicenter trial designed to compare antibiotic therapy (ertapenem) with emergency appendectomy in the treatment of uncomplicated AA. The primary endpoint of the study is the success of the randomized treatment. In the antibiotic treatment arm successful treatment is defined as being discharged from the hospital without the need for surgical intervention and no recurrent appendicitis during a minimum follow-up of one-year (treatment efficacy). Treatment efficacy in the operative treatment arm is defined as successful appendectomy evaluated to be 100%. Secondary endpoints are post-intervention complications, overall morbidity and mortality, the length of hospital stay and sick leave, treatment costs and pain scores (VAS, visual analoque scale). A maximum of 610 adult patients (aged 18-60 years) with a CT scan confirmed uncomplicated AA will be enrolled from six hospitals and randomized by a closed envelope method in a 1:1 ratio either to undergo emergency appendectomy or to receive ertapenem (1 g per day) for three days continued by oral levofloxacin (500 mg per day) plus metronidazole (1.5 g per day) for seven days. Follow-up by a telephone interview will be at 1 week, 2 months and 1, 3, 5 and 10 years; the primary and secondary endpoints of the trial will be evaluated at each time point. The APPAC trial aims to provide level I evidence to support the hypothesis that approximately 75-85% of patients with uncomplicated AA can be treated with effective antibiotic therapy avoiding unnecessary appendectomies and the related operative morbidity, also resulting in major cost savings.

Antibiotic therapy for acute uncomplicated appendicitis is effective in adult patients, but its application in pediatric patients remains controversial. To compare the safety and efficacy of antibiotic treatment vs appendectomy as the primary therapy for acute uncomplicated appendicitis in pediatric patients. The PubMed, MEDLINE, EMBASE, and Cochrane Library databases and the Cochrane Controlled Trials Register for randomized clinical trials were searched through April 17, 2016. The search was limited to studies published in English. Search terms included appendicitis, antibiotics, appendectomy, randomized controlled trial, controlled clinical trial, randomized, placebo, drug therapy, randomly, and trial. Randomized clinical trials and prospective clinical controlled trials comparing antibiotic therapy with appendectomy for acute uncomplicated appendicitis in pediatric patients (aged 5-18 years) were included in the meta-analysis. The outcomes included at least 2 of the following terms: success rate of antibiotic treatment and appendectomy, complications, readmissions, length of stay, total cost, and disability days. Data were independently extracted by 2 reviewers. The quality of the included studies was examined in accordance with the Cochrane guidelines and the Newcastle-Ottawa criteria. Data were pooled using a logistic fixed-effects model, and the subgroup pooled risk ratio with or without appendicolith was estimated. The primary outcome was the success rate of treatment. The hypothesis was formulated before data collection. A total of 527 articles were screened. In 5 unique studies, 404 unique patients with uncomplicated appendicitis (aged 5-15 years) were enrolled. Nonoperative treatment was successful in 152 of 168 patients (90.5%), with a Mantel-Haenszel fixed-effects risk ratio of 8.92 (95% CI, 2.67-29.79; heterogeneity, P = .99; I2 = 0%). Subgroup analysis showed that the risk for treatment failure in patients with appendicolith increased, with a Mantel-Haenszel fixed-effects risk ratio of 10.43 (95% CI, 1.46-74.26; heterogeneity, P = .91; I2 = 0%). This meta-analysis shows that antibiotics as the initial treatment for pediatric patients with uncomplicated appendicitis may be feasible and effective without increasing the risk for complications. However, the failure rate, mainly caused by the presence of appendicolith, is higher than for appendectomy. Surgery is preferably suggested for uncomplicated appendicitis with appendicolith.

All obese pregnant women are considered at equal high risk with respect to complications in pregnancy and birth, and are commonly managed through resource-intensive care pathways. However, the identification of maternal characteristics associated with normal pregnancy outcomes could assist in the management of these pregnancies. The present study aims to identify the factors associated with uncomplicated pregnancy and birth in obese women, and to assess their predictive performance. Data form obese women (BMI ≥ 30 kg/m 2 ) with singleton pregnancies included in the UPBEAT trial were used in this analysis. Multivariable logistic regression was used to identify sociodemographic, clinical and biochemical factors at 15 +0 to 18 +6 weeks' gestation associated with uncomplicated pregnancy and birth, defined as delivery of a term live-born infant without antenatal or labour complications. Predictive performance was assessed using area under the receiver operating characteristic curve (AUROC). Internal validation and calibration were also performed. Women were divided into fifths of risk and pregnancy outcomes were compared between groups. Sensitivity, specificity, and positive and negative predictive values were calculated using the upper fifth as the positive screening group. Amongst 1409 participants (BMI 36.4, SD 4.8 kg/m 2 ), the prevalence of uncomplicated pregnancy and birth was 36% (505/1409). Multiparity and increased plasma adiponectin, maternal age, systolic blood pressure and HbA1c were independently associated with uncomplicated pregnancy and birth. These factors achieved an AUROC of 0.72 (0.68-0.76) and the model was well calibrated. Prevalence of gestational diabetes, preeclampsia and other hypertensive disorders, preterm birth, and postpartum haemorrhage decreased whereas spontaneous vaginal delivery increased across the fifths of increasing predicted risk of uncomplicated pregnancy and birth. Sensitivity, specificity, and positive and negative predictive values were 38%, 89%, 63% and 74%, respectively. A simpler model including clinical factors only (no biomarkers) achieved an AUROC of 0.68 (0.65-0.71), with sensitivity, specificity, and positive and negative predictive values of 31%, 86%, 56% and 69%, respectively. Clinical factors and biomarkers can be used to help stratify pregnancy and delivery risk amongst obese pregnant women. Further studies are needed to explore alternative pathways of care for obese women demonstrating different risk profiles for uncomplicated pregnancy and birth.

Importance Antibiotic therapy for acute uncomplicated appendicitis is effective in adult patients, but its application in pediatric patients remains controversial. Objective To compare the safety and efficacy of antibiotic treatment vs appendectomy as the primary therapy for acute uncomplicated appendicitis in pediatric patients. Data Sources The PubMed, MEDLINE, EMBASE, and Cochrane Library databases and the Cochrane Controlled Trials Register for randomized clinical trials were searched through April 17, 2016. The search was limited to studies published in English. Search terms included appendicitis, antibiotics, appendectomy, randomized controlled trial, controlled clinical trial, randomized, placebo, drug therapy, randomly, and trial. Study Selection Randomized clinical trials and prospective clinical controlled trials comparing antibiotic therapy with appendectomy for acute uncomplicated appendicitis in pediatric patients (aged 5-18 years) were included in the meta-analysis. The outcomes included at least 2 of the following terms: success rate of antibiotic treatment and appendectomy, complications, readmissions, length of stay, total cost, and disability days. Data Extraction and Synthesis Data were independently extracted by 2 reviewers. The quality of the included studies was examined in accordance with the Cochrane guidelines and the Newcastle-Ottawa criteria. Data were pooled using a logistic fixed-effects model, and the subgroup pooled risk ratio with or without appendicolith was estimated. Main Outcomes and Measures The primary outcome was the success rate of treatment. The hypothesis was formulated before data collection. Results A total of 527 articles were screened. In 5 unique studies, 404 unique patients with uncomplicated appendicitis (aged 5-15 years) were enrolled. Nonoperative treatment was successful in 152 of 168 patients (90.5%), with a Mantel-Haenszel fixed-effects risk ratio of 8.92 (95% CI, 2.67-29.79; heterogeneity, P = .99; I2 = 0%). Subgroup analysis showed that the risk for treatment failure in patients with appendicolith increased, with a Mantel-Haenszel fixed-effects risk ratio of 10.43 (95% CI, 1.46-74.26; heterogeneity, P = .91; I2 = 0%). Conclusions and Relevance This meta-analysis shows that antibiotics as the initial treatment for pediatric patients with uncomplicated appendicitis may be feasible and effective without increasing the risk for complications. However, the failure rate, mainly caused by the presence of appendicolith, is higher than for appendectomy. Surgery is preferably suggested for uncomplicated appendicitis with appendicolith.

Right-sided hydronephrosis as a sign of appendicitis occurs rarely in the literature. To our knowledge, this is the first published account of the occurrence of right-sided hydronephrosis as a result of uncomplicated appendicitis. We describe a 15 year old patient referred to the emergency department with suspected appendicitis. Additional ultrasound examination showed a right-sided hydronephrosis. This finding was discussed with the urologist who noted the hydronephrosis as a chance finding. Because of persistent clinical suspicion of appendicitis, a diagnostic laparoscopy was performed. A retrocaecal appendicitis with secondary hydronephrosis was found. Right-sided hydronephrosis may be a sign of acute uncomplicated (retrocaecal) appendicitis. It is important to keep sight of these findings, especially in view of the emphasis on imaging techniques in the current Dutch guideline on appendicitis.

In sub-Saharan Africa, sigmoid volvulus is a frequent cause of bowel obstruction. The aim of this study was to evaluate the results of acute sigmoid resection and anastomosis via a mini-laparotomy in patients with uncomplicated sigmoid volvulus, following the principles of "Enhanced Recovery After Surgery (ERAS)", in a low-resource setting. Patients with uncomplicated sigmoid volvulus were operated acutely, via a mini-laparotomy, according to the principles of ERAS. Intraoperative complications, duration of operation, morbidity, mortality and length of hospital stay were evaluated, retrospectively. From 1 March 2012 to 1 September 2017, 31 consecutive patients were treated with acute sigmoid resection and anastomosis, via a mini-laparotomy. There were 29 men and 2 women, median age 57 (range 17-92) years. Patients were operated after a median period of 4 (range 1.5-18) hours. The median duration of the operative procedure was 50 (range 30-105) minutes. Two patients died (6.3%). One patient died during an uncomplicated operation. The cause of death is unknown. One patient with a newly diagnosed HIV infection had an anastomotic dehiscence. After Hartmann's procedure, he died on the 17th post-operative day as a result of a HIV-related double-sided pneumonia, without signs of abdominal sepsis. One patient had an urinary retention and 1 patient haematuria after bladder catheter insertion. Acute sigmoid resection and primary anastomosis via a mini-laparotomy for uncomplicated sigmoid volvulus, without preoperative endoscopic decompression is a safe procedure with a low morbidity and mortality.

Objective To compare the safety and efficacy of antibiotic treatment versus appendicectomy for the primary treatment of uncomplicated acute appendicitis. Design Meta-analysis of randomised controlled trials. Population Randomised controlled trials of adult patients presenting with uncomplicated acute appendicitis, diagnosed by haematological and radiological investigations. Interventions Antibiotic treatment versus appendicectomy. Outcome measures The primary outcome measure was complications. The secondary outcome measures were efficacy of treatment, length of stay, and incidence of complicated appendicitis and readmissions. Results Four randomised controlled trials with a total of 900 patients (470 antibiotic treatment, 430 appendicectomy) met the inclusion criteria. Antibiotic treatment was associated with a 63% (277/438) success rate at one year. Meta-analysis of complications showed a relative risk reduction of 31% for antibiotic treatment compared with appendicectomy (risk ratio (Mantel-Haenszel, fixed) 0.69 (95% confidence interval 0.54 to 0.89); I2=0%; P=0.004). A secondary analysis, excluding the study with crossover of patients between the two interventions after randomisation, showed a significant relative risk reduction of 39% for antibiotic therapy (risk ratio 0.61 (0.40 to 0.92); I2=0%; P=0.02). Of the 65 (20%) patients who had appendicectomy after readmission, nine had perforated appendicitis and four had gangrenous appendicitis. No significant differences were seen for treatment efficacy, length of stay, or risk of developing complicated appendicitis. Conclusion Antibiotics are both effective and safe as primary treatment for patients with uncomplicated acute appendicitis. Initial antibiotic treatment merits consideration as a primary treatment option for early uncomplicated appendicitis. PMID:22491789

Prior work has shown Medicaid and self-pay insurance status is associated with emergency department (ED), rather than outpatient clinic, presentation for uncomplicated acute rhinosinusitis (ARS). We investigate whether the disparate use of ED resources for this nonemergent condition by patients with Medicaid and self-pay insurance can be attributed to presentation overnight or on weekends. Cross-sectional survey of 990,849 patients from the 2009 and 2010 National Hospital Ambulatory Medical Care Survey presenting to EDs with uncomplicated ARS. Patients with orbital and intracranial complications of ARS were excluded. Univariate and multivariate associations identified demographic and socioeconomic characteristics, including insurance status, which were independently associated with overnight (between 5 pm and 7 am) or daytime weekend ED presentation for uncomplicated ARS. Medicaid or self-pay insurance status was associated with evening/overnight ED presentation (odds ratio=1.88, P=.018) in comparison to private or Medicare insurance. However, weekend daytime ED presentation was not associated with Medicaid or self-pay insurance statuses (P=.144). Income and education levels of patients' zip codes, taken as markers of socioeconomic status, were not associated with either evening/overnight or daytime weekend ED presentation for uncomplicated ARS (P>.05). ARS patients with Medicaid or self-pay status, previously shown to preferentially use EDs for uncomplicated ARS, were more likely to present for overnight ED care compared to patients with private insurance or Medicare. These findings suggest a potential lack of access to extended-hours primary care during evenings and nights for Medicaid patients. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

2006-01-01

Background Recent guidelines from NICE have proposed that open access gastroscopy is largely limited to patients with “alarm” symptoms. Aims and methods This study reviewed the outcome of all our patients with verified oesophageal or gastric carcinoma who presented with uncomplicated dyspepsia to see if endoscopic investigation is warranted in this group. All patients with histologically verified upper gastrointestinal (GI) cancers who presented over a period from 1998 to 2002 were identified. Their presenting symptoms, treatment, and outcome were analysed. Results 228 upper GI cancers (119 oesophageal, 109 gastric; mean age 72 years (29–99 years); 130 male, 82 female) were identified in 11 145 endoscopies performed. Only 14 patients (6.2%) presented without alarm symptoms; three patients were under 55 years of age and all had gastric carcinoma—one of these had chronic diarrhoea only. Eleven had dyspepsia or reflux symptoms only, and two were under surveillance for Barrett's oesophagus. Only five patients had a curative surgical resection and are still alive two—six years from diagnosis. A sixth patient had a curative operation but died of a cerebrovascular accident one year later. The remaining eight patients unfortunately had either metastatic disease or comorbidity, which precluded surgery. All of these died within two years of diagnosis, mean survival 10 months. Conclusion Only five patients with dyspepsia and no alarm symptoms had resectable upper GI malignancies over a four year period. Limiting open access gastroscopy to those with alarm features only would “miss” a small number of patients who have curable upper GI malignancy. PMID:16397081

Diverticular disease is one of the most common disorders of the gastrointestinal tract. 28-45% of the population develop colonic diverticula, while about 25% suffer symptoms and about 5% complications. To create formal guidelines for diagnosis and management. Six working groups with 44 participants analyzed key questions in subject areas assigned to them. Following a systematic literature search, 451 publications were included. Consensus was obtained by agreement within the working groups, two Delphi processes and a guideline conference. Targeted management of diverticular disease requires a classificatory diagnosis. A new classification was created. In addition to the clinical examination, intestinal ultrasound or computed tomography is the determining factor. Interval colonoscopy is recommended to exclude comorbidities. A low-fiber diet, obesity, lack of exercise, smoking and immunosuppression have an adverse impact on diverticulosis. This can lead to diverticulitis. Antibiotics are no longer recommended in uncomplicated diverticulitis if no risk factors such as immunosuppression are present. If close monitoring is ensured, uncomplicated diverticulitis can be treated on an outpatient basis. Complicated diverticulitis should be treated in hospital, involving broad-spectrum antibiotic therapy, where necessary abscess drainage, and surgery, if possible laparoscopically. In the case of chronic relapsing diverticulitis, the risk of perforation decreases with each episode, so that surgery is no longer recommended after the second episode but only following individual assessment. New findings on diverticular disease call into question the overuse of antibiotics and excessive indications for surgery. Targeted treatment requires a precise diagnosis and intensive interdisciplinary cooperation. © 2014 S. Karger AG, Basel.

Malaria infection during pregnancy is associated with an increased risk for maternal and fetal complications. In the United States, treatment options for uncomplicated, chloroquine-resistant Plasmodium falciparum and P. vivax malaria in pregnant women are limited to mefloquine or quinine plus clindamycin (1). However, limited availability of quinine and increasing resistance to mefloquine restrict these options. Strong evidence now demonstrates that artemether-lumefantrine (AL) (Coartem) is effective and safe in the treatment of malaria in pregnancy. The World Health Organization (WHO) has endorsed artemisinin-based combination therapies (ACTs), such as AL, for treatment of uncomplicated malaria during the second and third trimesters of pregnancy and is currently considering whether to add ACTs, including AL, as an option for malaria treatment during the first trimester (2,3). This policy note reviews the evidence and updates CDC recommendations to include AL as a treatment option for uncomplicated malaria during the second and third trimesters of pregnancy and during the first trimester of pregnancy when other treatment options are unavailable. These updated recommendations reflect current evidence and are consistent with WHO treatment guidelines.

Minimum inhibitory concentrations (MICs) of six penicillins against 95 strains of Neisseria gonorrhoeae from patients with uncomplicated anogenital infections and 22 strains from women with pelvic inflammatory disease were determined by an agar plate dilution method, using an inocula replicator. Against all 117 strains, the order of activity observed was: BL-P1654 > penicillin X > penicillin G > ampicillin > amoxicillin = carbenicillin. MICs against strains isolated from women with gonococcal pelvic inflammatory disease were significantly higher than those against isolates from uncomplicated infections: BL-P1654, P < 0.001; penicillin X, P < 0.001; penicillin G, P < 0.001; ampicillin, P < 0.001; and amoxicillin, P < 0.05. MICs of penicillin G were ≥0.125 μg/ml against 33 (36%) of the 92 strains from patients with uncomplicated infections, as contrasted with 15 (68%) of the 22 isolates from women with pelvic inflammatory disease (P < 0.01). The means of the MICs of penicillin G were 0.06 μg/ml for the former and 0.14 μg/ml for the latter. PMID:407840

Diagnosis and management of urinary tract infections in the emergency department.

Best, Jessica; Kitlowski, Andrew David; Ou, Derek; Bedolla, John

2014-07-01

Urinary tract infections are a heterogeneous group of disorders, involving infection of all or part of the urinary tract, and are defined by bacteria in the urine with clinical symptoms that may be acute or chronic. Approximately 1 million urinary tract infections are treated every year in United States emergency departments. The female-to-male ratio is 6:1. Urinary tract infections are categorized as upper versus lower tract involvement and as uncomplicated versus complicated. The emergency clinician must carefully categorize the infection and take into account patient host factors to optimally treat and disposition patients. A working knowledge of local or at least national susceptibility patterns of the most likely pathogens is essential. A variety of special populations exist that require special management, including pregnant females, patients with anatomic abnormalities, and instrumented patients.

2014 Hypertension Guideline: Recommendation for a Change in Goal Systolic Blood Pressure

Handler, Joel

2015-01-01

The 2014 Kaiser Permanente Care Management Institute National Hypertension Guideline was developed to assist primary care physicians and other health care professionals in the outpatient treatment of uncomplicated hypertension in adult men and nonpregnant women aged 18 years and older. The new guideline reflects general acceptance, with minor modifications, of the “Evidence-Based Guideline” report by the panel members appointed to the National Heart, Lung, and Blood Institute 8th Joint National Committee. A major practice change is the recommendation for goal systolic blood pressure less than 150 mmHg in patients aged 60 years and older who are treated for hypertension in the absence of diabetes or chronic kidney disease. This article describes the reasons for, evidence for, and consequences of the change, and is followed by the National Guidelines handout. PMID:26057683

Endovascular treatment as a bridge to successful surgical revascularization for chronic mesenteric ischemia.

PubMed

Biebl, Matthias; Oldenburg, W Andrew; Paz-Fumagalli, Ricardo; McKinney, J Mark; Hakaim, Albert G

2004-11-01

Chronic mesenteric ischemia (CMI) can be treated with surgical revascularization or with angioplasty and stenting. As experience has been gained, endovascular treatment appears safe and effective in selected patients. Currently, surgical revascularization has better success and patency rates but also a higher short- and midterm mortality and morbidity, especially in patients at high surgical risk. A 72-year-old female with severe respiratory dysfunction presented with CMI resulting in profound malnutrition. Serial percutaneous interventions averted urgent surgery and reversed the mesenteric ischemia. Nine months later, after repeated angioplasty and stenting had failed, elective uncomplicated iliomesenteric bypass, in a medically optimized patient, resolved the ischemia. At an 18-month follow-up, the graft remained widely patent and the patient asymptomatic with a body weight corresponding to her ideal body weight. Compared to surgical revascularization, reocclusion or restenosis occurs more frequently after endovascular treatment of CMI, and reintervention may be necessary. Nevertheless, percutaneous intervention effectively provides relief from mesenteric ischemia and has lower perioperative complication rates compared to surgery in patients at high surgical risk. After initial relief of the CMI, the patient's condition may improve, allowing for more definitive secondary surgical revascularization, if needed.

2009-09-30

Clinical association studies have yielded varied results regarding the impact of glucose-6-phosphate dehydrogenase (G6PD) deficiency upon susceptibility to malaria. Analyses have been complicated by varied methods used to diagnose G6PD deficiency. We compared the association between uncomplicated malaria incidence and G6PD deficiency in a cohort of 601 Ugandan children using two different diagnostic methods, enzyme activity and G6PD genotype (G202A, the predominant East African allele). Although roughly the same percentage of males were identified as deficient using enzyme activity (12%) and genotype (14%), nearly 30% of males who were enzymatically deficient were wild-type at G202A. The number of deficient females was three-fold higher with assessment by genotype (21%) compared to enzyme activity (7%). Heterozygous females accounted for the majority (46/54) of children with a mutant genotype but normal enzyme activity. G6PD deficiency, as determined by G6PD enzyme activity, conferred a 52% (relative risk [RR] 0.48, 95% CI 0.31-0.75) reduced risk of uncomplicated malaria in females. In contrast, when G6PD deficiency was defined based on genotype, the protective association for females was no longer seen (RR = 0.99, 95% CI 0.70-1.39). Notably, restricting the analysis to those females who were both genotypically and enzymatically deficient, the association of deficiency and protection from uncomplicated malaria was again demonstrated in females, but not in males (RR = 0.57, 95% CI 0.37-0.88 for females). This study underscores the impact that the method of identifying G6PD deficient individuals has upon association studies of G6PD deficiency and uncomplicated malaria. We found that G6PD-deficient females were significantly protected against uncomplicated malaria, but this protection was only seen when G6PD deficiency is described using enzyme activity. These observations may help to explain the discrepancy in some published association studies involving G6PD deficiency and uncomplicated malaria.

Severity of complicated versus uncomplicated subthreshold depression: New evidence on the "Monotonicity Thesis" from the national comorbidity survey.

PubMed

Wakefield, Jerome C; Schmitz, Mark F

2017-04-01

"Complicated" subthreshold depression (CsD) includes at least one of six pathosuggestive "complicated" symptoms: >6 months duration, marked role impairment, sense of worthlessness, suicidal ideation, psychotic ideation, and psychomotor retardation. "Uncomplicated" subthreshold depression (UsD) has no complicated features. Whereas studies show that complicated (CMDD) versus uncomplicated (UMDD) major depression differ substantially in severity and prognosis, UsD and CsD severity has not been previously compared. This study evaluates UsD and CsD pathology validator levels and examines whether the complicated/uncomplicated distinction offers incremental concurrent validity over the standard number-of-symptoms dimension as a depression severity measure. Using nationally representative community data from the National Comorbidity Survey, seven depression lifetime history subgroups were identified: one MDD screener symptom (n=1432); UsD (n=430); CsD (n=611); UMDD (n=182); and CMDD with 5-6 symptoms (n=518), 7 symptoms (n=217), and 8-9 symptoms (n=291). Severity was evaluated using five concurrent pathology validators: suicide attempt, interference with life, help seeking, hospitalization, and generalized anxiety disorder. CsD validator levels are substantially higher than both UsD and UMDD levels, and similar to mild CMDD, disconfirming the "monotonicity thesis" that severity increase with symptom number. Complicated/uncomplicated status predicts severity, and when complicatedness is controlled, number of symptoms no longer predicts validator levels. Diagnoses were based on respondents' fallible retrospective symptom reports during a lay-administered structured interview, which may not yield diagnoses comparable to clinicians' assessments. CsD is more severe than UsD and comparable to mild MDD. Complicated status more validly indicates depression severity than the standard number-of-symptoms measure. Copyright © 2017 Elsevier B.V.

Objective To compare the occurrence of injuries in adolescents with childhood-onset epilepsy and matched sibling controls. Study design Retrospective case-control lifetime injury assessments were obtained from a community-based cohort of adolescents with childhood-onset epilepsy diagnosed 9-years earlier, and their siblings. Children with epilepsy (n=501; mean age 15.3 years) included children with complicated (abnormal neurological exam or IQ<80; n=133) and uncomplicated (normal neurological exam and IQ≥80; n=368) epilepsy. Children with uncomplicated epilepsy were matched to sibling controls (n=210 pairs). Children reported whether they had ever (before and after epilepsy diagnosis) experienced injuries, “serious enough to require medical attention” and the type of treatment required. Results 49.1% of children with epilepsy experienced any injury, of whom 8.9% required surgery/hospitalization and 17.1% had an injury due to a seizure; fewer children with uncomplicated epilepsy had seizure-related injuries versus those with complicated epilepsy (13.6% vs. 27.4%; p≤0.01). The proportion of children with epilepsy with any injury by types (not mutually exclusive) were: 25.2% (n=126) fractures, 24.4% (n=122) head, 10.2% (n=51) other, 8.4% (n=42) dental and 8% (n=40) burns/scalds. A similar proportion of children with uncomplicated epilepsy experienced any injury (overall and by type) compared with matched sibling controls, with the exception that more children with uncomplicated epilepsy had head injuries (30.0% vs. 19.5%; p<0.02). Conclusion With the exception of head injuries, in a representative cohort of children with epilepsy compared with siblings there was no evidence of an increased risk of injury. This may reflect that the sample was not biased to more severe cases or that safety precautions to prevent injury were widely employed. PMID:24054432

In Morocco, medical care for women with severe obstetric complications (near-miss cases) ends at discharge from the hospital. Little information exists regarding what happens after returning home. The aim of the study was to assess the physical and mental health consequences of near-miss events on Moroccan women 8 months after childbirth. A prospective cohort study of 76 near-miss women was conducted in three hospitals. For every case, we recruited at least two women from the same hospital who had uncomplicated deliveries (n = 169). We used a mixed-methods approach. For the quantitative part, we analysed sociodemographic characteristics collected via a questionnaire and medical complications extracted from the medical records during a medical consultation at 8 months post-partum. Forty in-depth interviews were also conducted with 20 near-miss cases and 20 women with uncomplicated deliveries. The near-miss women were poorer and less educated than those who had uncomplicated deliveries. The proportion of physical consequences (serious illness) was higher among near-miss cases (22%) than uncomplicated deliveries (6%, P = 0.001). The risk of depression was significantly higher among near-miss cases with perinatal death (OR = 7.16; [95% CI: 2.85-17.98]) than among those who had an uncomplicated delivery. Interviews revealed that the economic burden of near-miss care contributed to social problems among the women and their households. A near-miss event has consequences that go beyond the first days after delivery. Developing new mechanisms for maternal and newborn health follow-up is essential and should address the mother's physical and mental health problems and involve husbands and family members. © 2015 The Authors.

The role of laparoscopic surgery in the management of patients with diverticular disease is still not universally accepted. The aim of our study was to evaluate the results of laparoscopic surgery for diverticular disease in a centre with a specialist interest in minimally invasive surgery. All diverticular resections carried out between 2006 and 2010 were reviewed. Data recorded included baseline demographics, indication for surgery, operative details, length of hospital stay and complications. Complicated diverticular disease was defined as diverticulitis with associated abscess, phlegmon, fistula, stricture, obstruction, bleeding or perforation. One hundred and two patients (58 men) who had surgery for diverticular disease were identified (median age 59 years, range 49-70 years). Sixty-four patients (64%) had surgery for complicated diverticular disease. The indications were recurrent acute diverticulitis (37%), colovesical fistula (21%), stricture formation (17%) and colonic perforation (16%). Sixty-nine cases (88%) were completed by elective laparoscopy. Postoperative mortality was 0%. For elective cases there was no difference in morbidity rates between patients with complicated and uncomplicated diverticular disease. The overall anastomotic leakage rate was 1% and the wound infection rate 7%. There was a nonsignificant trend to higher conversion to open surgery in the elective group in complicated (11.4%) compared with uncomplicated patients (5.2%) (P=0.67). Electively, the rate of stoma formation was higher in the complicated (31.6%) than the uncomplicated group (5.2%) (P<0.02). Laparoscopic surgery for both complicated and uncomplicated diverticular disease is associated with low rates of postoperative morbidity and relatively low conversion rates. Laparoscopic surgery is now the standard of care for complicated and uncomplicated diverticular disease in our institution. © 2011 The Authors.

The aim of this study was to compare the effectiveness of extended versus narrow spectrum antibiotics in preventing surgical site infections (SSIs) and hospital revisits in children with uncomplicated appendicitis. There is a paucity of high-quality evidence in the pediatric literature comparing the effectiveness of extended versus narrow-spectrum antibiotics in the prevention of SSIs associated with uncomplicated appendicitis. Clinical data from the ACS NSQIP-Pediatric Appendectomy Pilot Project were merged with antibiotic utilization data from the Pediatric Health Information System database for patients undergoing appendectomy for uncomplicated appendicitis at 17 hospitals from January 1, 2013 to June 30, 2015. Patients who received piperacillin/tazobactam (extended spectrum) were compared with those who received either cefoxitin or ceftriaxone with metronidazole (narrow spectrum) after propensity matching on demographic and severity characteristics. Study outcomes were 30-day SSI and hospital revisit rates. Of the 1389 patients included, 39.1% received piperacillin/tazobactam (range by hospital: 0% to 100%), and the remainder received narrow-spectrum agents. No differences in demographics or severity characteristics were found between groups following matching. In the matched analysis, the rates of SSI were similar between groups [extended spectrum: 2.4% vs narrow spectrum 1.8% (odds ratio, OR: 1.05, 95% confidence interval, 95% CI 0.34-3.26)], as was the rate of revisits [extended spectrum: 7.9% vs narrow spectrum 5.1% (OR: 1.46, 95% CI 0.75-2.87)]. Use of extended-spectrum antibiotics was not associated with lower rates of SSI or hospital revisits when compared with narrow-spectrum antibiotics in children with uncomplicated appendicitis. Our results challenge the routine use of extended-spectrum antibiotics observed at many hospitals, particularly given the increasing incidence of antibiotic-resistant organisms.

Nonoperative management (NOM) of uncomplicated pediatric appendicitis has promise but remains poorly studied. NOM may lead to an increase in resource utilization. Our objective was to investigate the trends in NOM for uncomplicated appendicitis and study the relevant clinical outcomes including subsequent appendectomy, complications, and resource utilization. Retrospective analysis of administrative data from 45 US pediatric hospitals. Patients <19 years of age presenting to the emergency department (ED) with appendicitis between 2010 and 2016 were studied. NOM was defined by an ED visit for uncomplicated appendicitis treated with antibiotics and the absence of appendectomy at the index encounter. The main outcomes included trends in NOM among children with uncomplicated appendicitis and frequency of subsequent diagnostic imaging, ED visits, hospitalizations, and appendectomy during 12-month follow-up. 99 001 children with appendicitis were identified, with a median age of 10.9 years. Sixty-six percent were diagnosed with nonperforated appendicitis, of which 4190 (6%) were managed nonoperatively. An increasing number of nonoperative cases were observed over 6 years (absolute difference, +20.4%). During the 12-month follow-up period, NOM patients were more likely to have the following: advanced imaging (+8.9% [95% confidence interval (CI) 7.6% to 10.3%]), ED visits (+11.2% [95% CI 9.3% to 13.2%]), and hospitalizations (+43.7% [95% CI 41.7% to 45.8%]). Among patients managed nonoperatively, 46% had a subsequent appendectomy. A significant increase in NOM of nonperforated appendicitis was observed over 6 years. Patients with NOM had more subsequent ED visits and hospitalizations compared with those managed operatively at the index visit. A substantial proportion of patients initially managed nonoperatively eventually had an appendectomy. Copyright © 2017 by the American Academy of Pediatrics.

Mefloquine and artesunate combination therapy is the recommended first-line treatment for uncomplicated malaria throughout much of south-east Asia. Concerns have been raised about the potential central nervous system (CNS) effects of both drug components and there are no detailed reports in very young children. Children, aged between three months and five years, with acute uncomplicated Plasmodium falciparum malaria were randomized to either 7 days of artesunate monotherapy or the same schedule of artesunate plus mefloquine on day 7 and 8. Neurological testing targeting coordination and behaviour was carried out at day 0, 7, 9, 10, 14 and 28. Non-febrile healthy control children from the same population were tested on days 0, 7, 14 and 28. From December 1994 to July 1997, 91 children with uncomplicated P. falciparum, 45 treated with artesunate monotherapy, 46 treated with mefloquine and artesunate combination therapy and 36 non-febrile controls, underwent neurological testing. Malaria and fever had a significant negative impact on testing performance. By contrast, the anti-malarial treatments were not associated with worsening performances in the various components of the test. Artesunate and mefloquine do not appear to have a significant influence on coordination and behaviour. Children treated with mefloquine were significantly less likely to suffer recurrent malaria infection during follow-up compared to those treated with artesunate alone (P = 0.033). In keeping with the results of randomized controlled trials in adults, mefloquine was not associated with a decrease in specific items of neurological performance. Likewise, children treated with artesunate did not perform significantly differently to control children. This study does not exclude subtle or rare treatment CNS effects of artesunate or mefloquine. Treatment of acute uncomplicated malaria results in a significant improvement on items of neurological performance.

To determine the incidence and characteristics of women with uncomplicated recurrent urinary tract infections (UTIs) and to explore whether the use of culture-driven treatment affects rates of UTI-related complications and resource utilization. Using MarketScan claims from 2003 to 2011, we identified UTI-naive women ages 18-64 with incident-uncomplicated recurrent UTIs. Recurrent UTIs were defined as 3 UTI visits associated with antibiotics during a 12-month period. Cases were excluded if they had a UTI in the preceding year, or if they had any complicating factors (eg, abnormality of the urinary tract, neurologic condition, pregnancy, diabetes, or currently taking immunosuppression). We next assessed use of urine cultures, imaging, and cystoscopy, and performed propensity score matching with logistic regression to determine whether having a urine culture associated with >50% of UTIs affected rates of complications and downstream resource utilization. We identified 48,283 women with incident-uncomplicated recurrent UTIs, accounting for an overall incidence of 102 per 100,000 women, highest among women ages 18-34 and 55-64. Sixty-one percent of these women had at least 1 urine culture, 6.9% had imaging, and 2.8% had cystoscopy. Having a urine culture >50% of the time was associated with fewer UTI-related hospitalizations and lower rates of intravenous antibiotic use, whereas demonstrating higher rates of UTI-related office visits and pyelonephritis. The incidence of uncomplicated recurrent UTIs increases with age. Urine culture-directed care is beneficial in reducing high-cost services including UTI-related hospitalizations and intravenous antibiotic use, making urine cultures a valuable component to management of these patients.

To assess the quality of care provided by lady health workers (LHW) managing cases of uncomplicated severe acute malnutrition (SAM) in the community. Cross-sectional quality-of-care study. The feasibility of the implementation of screening and treatment for uncomplicated SAM in the community by LHW was tested in Sindh Province, Pakistan. An observational, clinical prospective multicentre cohort study compared the LHW-delivered care with the existing outpatient health facility model. LHW implementing treatment for uncomplicated SAM in the community. Oedema was diagnosed conducted correctly for 87·5 % of children; weight and mid upper-arm circumference were measured correctly for 60·0 % and 57·4 % of children, respectively. The appetite test was conducted correctly for 42·0 % of cases. Of all cases of SAM without complications assessed during the study, 68·0 % received the correct medical and nutrition treatment. The proportion of cases that received the correct medical and nutrition treatment and key counselling messages was 4·0 %. This quality-of-care study supports existing evidence that LHW are able to identify uncomplicated SAM, and a majority can provide appropriate nutrition and medical treatment in the community. However, the findings also show that their ability to provide the complete package with an acceptable level of care is not assured. Additional evidence on the impact of supervision and training on the quality of SAM treatment and counselling provided by LHW to children with SAM is required. The study has also shown that, as in other sectors, it is essential that operational challenges are addressed in a timely manner and that implementers receive appropriate levels of support, if SAM is to be treated successfully in the community.

The role of urodynamics (UDS) before surgery for stress urinary incontinence (SUI) remains a debated issue in female urology as well as in urogynaecology and it has been recently questioned on the basis of data coming from selected population of patients defined as "uncomplicated." The aim of this study was to investigate the percentage of "uncomplicated" patients undergoing urodynamic evaluations in six referral Italian centers. The secondary aim was to assess the prevalence of women, for whom the urodynamic evaluation could add new information to the pre-urodynamic picture and in how many cases these findings had a significant impact on patient management. The data of women who underwent urodynamic evaluation prior to surgery for stress urinary incontinence between 2008 and 2013 were retrospectively analyzed. According to the definition of the Value of Urodynamic Evaluation (ValUE) trial criteria, patients presenting with SUI were classified as "uncomplicated" or "complicated." Urodynamic observations were then compared with pre-urodynamic data. Overall, 2,053 female patients were considered. Only 740/2,053 (36.0%) patients were defined "uncomplicated" according to the definition used in the ValUE trial. The urodynamic observations were not consistent with the pre-urodynamic diagnosis in 1,276 out of 2,053 patients (62.2%). Voiding dysfunctions were urodynamically diagnosed in 394 patients (19.2%). Planned surgery was cancelled or modified in 304 patients (19.2%), due to urodynamic findings. "Uncomplicated" patients represent a minority among female SUI patients evaluated before surgery. In "complicated" patients, the role of urodynamic has not been challenged yet and UDS seems still mandatory. Neurourol.

To ascertain the efficacy of chloroquine as first line agent in treatment of uncomplicated malaria -caused by Plasmodium vivax in children---and to determine its current treatment practice in Pakistan. This pilot study was conducted at the Paediatrics Department of Combined Military Hospital (CMH), Lahore, Pakistan. Forty-eight children between six months and twelve years of age having positive blood film for Plasmodium vivax were included. They were treated with chloroquine as a drug of - choice. Efficacy of chloroquine was assessed by clinical response, absence of parasitaemia on day seven and twenty-eight after initiation of therapy. A survey was also conducted to determine the first line therapeutic choice of Paediatricians in the treatment of uncomplicated Plasmodium vivax malaria in children in Pakistan. The results showed 100% efficacy of chloroquine in treating uncomplicated malaria caused by Plasmodium vivax in children. Artemisin was preferred by 74.28% Paediatricians' in combination therapy as 1st line treatment. Guidelines proposed by Malaria Control Programme Pakistan (MCPP) in collaboration with World Health Organization (WHO) are comprehensive but not being adhered to. The recently reported resistance of Plasmodium vivax to artemisin should urge measures to implement WHO guidelines.

To ascertain whether pediatric obesity without clinically significant insulin resistance (IR) impacts brain structure and function. Thirty obese and 30 matched lean adolescents, all without clinically significant IR or a diagnosis of metabolic syndrome (MetS), received comprehensive endocrine, neuropsychological, and MRI evaluations. Relative to lean adolescents, obese non-IR adolescents had significantly lower academic achievement (i.e., arithmetic and spelling) and tended to score lower on working memory, attention, psychomotor efficiency, and mental flexibility. In line with our prior work on adolescent MetS, memory was unaffected in uncomplicated obesity. Reductions in the thickness of the orbitofrontal and anterior cingulate cortices as well as reductions of microstructural integrity in major white matter tracts without gross volume changes were also uncovered. It was documented, for the first time, that adolescents with uncomplicated obesity already have subtle brain alterations and lower performance in selective cognitive domains. When interpreting these preliminary data in the context of our prior reports of similar, but more extensive brain findings in obese adolescents with MetS and T2DM, it was concluded that "uncomplicated" obesity may also result in subtle brain alterations, suggesting a possible dose effect with more severe metabolic dysregulation giving rise to greater abnormalities.

An accurate diagnosis of acute appendicitis is important to avoid severe outcome or unnecessary surgery but management is controversial. The aim of study was to evaluate, in younger and older children, the efficacy of conservative management for uncomplicated appendicitis and the outcome of complicated forms underwent early surgery. Children with acute appendicitis were investigated by clinical, laboratory variables and abdominal ultrasound and divided in two groups: complicated and uncomplicated. Complicated appendicitis underwent early surgery; uncomplicated appendicitis started conservative treatment with antibiotic. If in the next 24-48h it was worsening, the conservative approach failed and patients underwent late surgery. A total of 362 pediatric patients were included. One hundred sixty-five underwent early appendectomy; 197 patients were at first treated conservatively: of these, 82 were operated within 24-48h for failure. The total percentage of operated patients was 68.2%. An elevated association was found between surgery and ultrasound. Conservative treatment for uncomplicated appendicitis had high percentage of success (58%). Complications in operated patients were infrequent. Our protocol was effective in order to decide which patients treat early surgically and which conservatively; specific red flags (age and onset) can identified patients at most risk of complications or conservative failure. treatment study.

To compare in a prospective, randomised, multicentre trial the relative merits of pre-discharge exercise ECG and early pharmacological stress echocardiography concerning risk stratification and costs of treating patients with uncomplicated acute myocardial infarction. 262 patients from six participating centres with a recent uncomplicated myocardial infarction were randomly assigned to early (day 3-5) pharmacological stress echocardiography (n = 132) or conventional pre-discharge (day 7-9) maximum symptom limited exercise ECG (n = 130). No complication occurred during either stress echocardiography or exercise ECG. At one year follow up there were 26 events (1 death, 5 non-fatal reinfarctions, 20 patients with unstable angina requiring hospitalisation) in patients randomly assigned to early stress echocardiography and 18 events (2 reinfarctions, 16 unstable angina requiring hospitalisation) in the group randomly assigned to exercise ECG (not significant). The negative predictive value was 92% for stress echocardiography and 88% for exercise ECG (not significant). Total costs of the two strategies were similar (not significant). Early pharmacological stress echocardiography and conventional pre-discharge symptom limited exercise ECG have similar clinical outcome and costs after uncomplicated infarction. Early pharmacological stress echocardiography should be considered a valid alternative even for patients with interpretable baseline ECG who can exercise.

Inflammation may be detected in diverticular disease (DD), and fibrosis may also develop. We assessed the mucosal expression of bFGF, SD1, and TNF-α in DD according to the severity of the disease. Moreover, we assessed the response to therapy of these cytokines in acute uncomplicated diverticulitis (AUD). Fifteen patients affected by AUD and seven patients affected by symptomatic uncomplicated diverticular disease (SUDD) were enrolled. Patients with asymptomatic diverticulosis (AD), segmental colitis associated with diverticulosis (SCAD), ulcerative colitis (UC), and healthy subjects (HC) served as control groups. The expression of bFGF, SD1, and TNF-α was significantly higher in diverticulitis than in healthy controls, in diverticulosis, and in uncomplicated diverticular disease. Cytokines were significantly higher in uncomplicated diverticular disease than in healthy controls. Cytokine expression in diverticulitis did not differ significantly from that of ulcerative colitis. After treatment, TNF-α expression dropped significantly. Mucosal TNF-α is overexpressed only in symptomatic DD, while SD1 and bFGF are already overexpressed in AD. Finally, TNF-α but not SD1 or bFGF expression seems to be influenced by the treatment in AUD. © 2012 Blackwell Publishing Ltd.

To compare the risk of complications between initial nonoperative treatment and appendectomy of uncomplicated (simple) appendicitis in children. Systematic literature search. Eligible for inclusion were both and randomized controlled trials and cohort studies including children in which the outcome of nonoperative treatment of uncomplicated appendicitis was reported with a minimum follow-up period of one year. Two authors extracted data independently and assessed quality. Primary outcome parameter was the percentage of children experiencing complications. Secondary outcomes were early failures, recurrent appendicitis and appendectomies, for all indications and on request. Five of the 2051 articles screened were eligible for inclusion, including 147 children (nonoperative treatment) and 173 children (appendectomy) with one year follow-up. Percentage of children experiencing complications ranged from 0 to 13% versus 0-17% for nonoperative and appendectomy, respectively. Nonoperative treatment avoided an appendectomy in 62-81% of the children after one year follow-up. The evidence base for initial nonoperative treatment of acute uncomplicated appendicitis in children is by far insufficient. It suggests that the percentage of patients experiencing complications in the initial nonoperative treatment group is comparable to the appendectomy group, and it may avoid an appendectomy in the large majority of children after one year follow-up.

In order to guide the antimalarial treatment policy of Somalia, we conducted therapeutic efficacy studies of routinely used antimalarial monotherapies as well as artemisinin-based combination therapies (ACTs) for uncomplicated malaria in three sentinel sites during 2003-2006. Therapeutic efficacy of chloroquine (CQ), amodiaquine (AQ) and sulfadoxine/pyrimetahmine (SP) monotherapies, and artesunate plus SP (AS+SP) or AQ (AS+AQ) were evaluated in children 6 months to 10 years old with uncomplicated malaria. For the assessment of the monotherapies, 2003 WHO protocol with 14-day follow-up was used while the 2005 WHO protocol with 28-day follow-up was used for testing the ACTs. Of the monotherapies, CQ performed very poorly with treatment failures varying from 76.5% to 88% between the sites. AQ treatment failure was low except for Janale site with treatment failure of 23.4% compared to 2.8% and 8% in Jamame and Jowhar, respectively. For SP, treatment failures from 7.8% to 12.2% were observed. A 28-day test of artemisinin-based combinations, AS+SP and AS+AQ, proved to be highly efficacious with cure rates of 98-100% supporting the choice of AS+SP combination as first line treatment for uncomplicated malaria for Somalia.

The standard medical therapy for haemochromatosis is iron removal by regular phlebotomy. Current guidelines suggest that this blood should be made available through national blood services. Here, we describe a pilot facilitating the process of blood donation amongst uncomplicated haemochromatosis patients. At a dedicated clinic, patients with uncomplicated haemochromatosis interested in becoming blood donors were offered an information leaflet and self-referral application. Upon receipt, members of the local Blood Service contacted them to confirm eligibility to donate. Data on demographics and clinical characteristics, including HFE (high Fe) genotype, co-morbidities, alcohol consumption and body mass index, were collected. Since establishing the clinic, 140 patients have attended (93 male) with median age 57. Most (n = 125; 89%) had uncomplicated haemochromatosis. Of these, 55 were potentially eligible blood donors. Amongst those eligible, there are now 29 regular blood donors, including 23 new. There is an interest and willingness to donate blood through the Blood Service amongst uncomplicated haemochromatosis patients undergoing therapeutic phlebotomy. Since the introduction of this facilitation process, we have significantly increased the number of regular donors amongst this cohort. If this process was to be replicated more widely across the UK, this could have a significant impact on the blood donor pool. © 2015 British Blood Transfusion Society.

Because value-based care is critical to the Affordable Care Act success, we forecasted inpatient costs and the potential impact of podiatric medical care on savings in the diabetic population through improved care quality and decreased resource use during implementation of the health reform initiatives in California. We forecasted enrollment of diabetic adults into Medicaid and subsidized health benefit exchange programs using the California Simulation of Insurance Markets (CalSIM) base model. Amputations and admissions per 1,000 diabetic patients and inpatient costs were based on the California Office of Statewide Health Planning and Development 2009-2011 inpatient discharge files. We evaluated cost in three categories: uncomplicated admissions, amputations during admissions, and discharges to a skilled nursing facility. Total costs and projected savings were calculated by applying the metrics and cost to the projected enrollment. Diabetic patients accounted for 6.6% of those newly eligible for Medicaid or health benefit exchange subsidies, with a 60.8% take-up rate. We project costs to be $24.2 million in the diabetic take-up population from 2014 to 2019. Inpatient costs were 94.3% higher when amputations occurred during the admission and 46.7% higher when discharged to a skilled nursing facility. Meanwhile, 61.0% of costs were attributed to uncomplicated admissions. Podiatric medical services saved 4.1% with a 10% reduction in admissions and amputations and an additional 1% for every 10% improvement in access to podiatric medical care. When implementing the Affordable Care Act, inclusion of podiatric medical services on multidisciplinary teams and in chronic-care models featuring prevention helps shift care to ambulatory settings to realize the greatest cost savings.

Pharmacological and clinical studies on the effects of angiotensin-converting enzyme (ACE) inhibitors support the idea of a central role played Angiotensin II which is able to cause cardiovascular and renal diseases also independently of its blood pressure elevating effects. The present investigation was aimed at evaluating the effect(s) of three different pharmacological regimens on both blood pressure and sympathetic drive in uncomplicated essential hypertension, by means of blood pressure laboratory measurements and ambulatory monitoring, 24-h heart rate variability and plasma noradrenaline levels. Thus, an ACE-inhibitor monotherapy (trandolapril, 2 mg/day), an AT(1)-receptor antagonist monotherapy (irbesartan, 300 mg/day), their low-dose combination (0.5 mg/day plus 150 mg/day, respectively) and placebo were given, in a randomised, single-blind, crossover fashion for a period of 3 weeks each to 12 mild essential hypertensives. Power spectral analysis (short recordings) and noradrenaline measurements were also performed in the supine position and after a postural challenge (60 degrees head-up tilting test: HUT). The low-dose combination therapy induced the greatest reduction in LF component and in LF/HF ratio, both in the resting and tilted positions, as well as in blood pressure. However, the physiological autonomic response to HUT was maintained. Noradrenaline plasma levels were lower after the combined therapy than after each drug alone. Our data demonstrate that in mild and uncomplicated essential hypertension, the chronic low-dose combination therapy with an ACE-inhibitor and an AT(1)-antagonist is more effective than the recommended full-dose monotherapy with either drug in influencing the autonomic regulation of the heart, suggesting a relative reduction in sympathetic drive both at cardiac and systemic levels.

Therapeutic efficacy and safety of dihydroartemisinin-piperaquine versus artesunate-mefloquine in uncomplicated Plasmodium falciparum malaria in India

PubMed Central

2012-01-01

Background Resistance in Plasmodium falciparum to commonly used anti-malarial drugs, especially chloroquine, is being increasingly documented in India. By 2007, the first-line treatment for uncomplicated malaria has been revised to recommend artemisinin-based combination therapy (ACT) for all confirmed P. falciparum cases. Objective The objective of this study was to compare the efficacy, safety and tolerability between dihydroartemisinin-piperaquine (DP) and artesunate plus mefloquine (A + M) drug combinations in the treatment of uncomplicated P. falciparum malaria in India. Methods Between 2006 and 2007, 150 patients with acute uncomplicated P. falciparum malaria were enrolled, randomized to DP (101) or A + M (49) and followed up for 63 days as part of an open-label, non-inferiority, randomized, phase III multicenter trial in Asia. Results The heterogeneity analysis showed no statistically significant difference between India and the other countries involved in the phase III study, for both the PCR-corrected and uncorrected cure rates. As shown at the whole study level, both forms of ACT were highly efficacious in India. In fact, in the per protocol population, the 63-day cure rates were 100% for A + M and 98.8% for DP. The DP combination exerted a significant post-treatment prophylactic effect, and compared with A + M a significant reduction in the incidence of new infections for DP was observed (respectively 17.1% versus 7.5% of patients experienced new infection within follow up). Parasite and fever clearance was rapid in both treatment arms (median time to parasite clearance of one day for both groups). Both DP and A + M were well tolerated, with the majority of adverse events of mild or moderate severity. The frequencies of individual adverse events were generally similar between treatments, although the incidence of post treatment adverse events was slightly higher in patients who received A + M with respect to those treated with DP. Conclusion DP is a new ACT displaying high efficacy and safety in the treatment of uncomplicated P. falciparum malaria and could potentially be considered for the first-line treatment of uncomplicated falciparum malaria in India.

Modeling the public health impact of malaria vaccines for developers and policymakers

PubMed Central

2013-01-01

Background Efforts to develop malaria vaccines show promise. Mathematical model-based estimates of the potential demand, public health impact, and cost and financing requirements can be used to inform investment and adoption decisions by vaccine developers and policymakers on the use of malaria vaccines as complements to existing interventions. However, the complexity of such models may make their outputs inaccessible to non-modeling specialists. This paper describes a Malaria Vaccine Model (MVM) developed to address the specific needs of developers and policymakers, who need to access sophisticated modeling results and to test various scenarios in a user-friendly interface. The model’s functionality is demonstrated through a hypothetical vaccine. Methods The MVM has three modules: supply and demand forecast; public health impact; and implementation cost and financing requirements. These modules include pre-entered reference data and also allow for user-defined inputs. The model includes an integrated sensitivity analysis function. Model functionality was demonstrated by estimating the public health impact of a hypothetical pre-erythrocytic malaria vaccine with 85% efficacy against uncomplicated disease and a vaccine efficacy decay rate of four years, based on internationally-established targets. Demand for this hypothetical vaccine was estimated based on historical vaccine implementation rates for routine infant immunization in 40 African countries over a 10-year period. Assumed purchase price was $5 per dose and injection equipment and delivery costs were $0.40 per dose. Results The model projects the number of doses needed, uncomplicated and severe cases averted, deaths and disability-adjusted life years (DALYs) averted, and cost to avert each. In the demonstration scenario, based on a projected demand of 532 million doses, the MVM estimated that 150 million uncomplicated cases of malaria and 1.1 million deaths would be averted over 10 years. This is equivalent to 943 uncomplicated cases and 7 deaths averted per 1,000 vaccinees. In discounted 2011 US dollars, this represents $11 per uncomplicated case averted and $1,482 per death averted. If vaccine efficacy were reduced to 75%, the estimated uncomplicated cases and deaths averted over 10 years would decrease by 14% and 19%, respectively. Conclusions The MVM can provide valuable information to assist decision-making by vaccine developers and policymakers, information which will be refined and strengthened as field studies progress allowing further validation of modeling assumptions.

Antibacterial resistances in uncomplicated urinary tract infections in women: ECO·SENS II data from primary health care in Austria

PubMed Central

2012-01-01

Background Uncomplicated urinary tract infections (UTI) are a frequent reason for consultation of women in primary health care. To avoid therapy failure and development of resistances, the choice of an antibiotic should be based on the knowledge of recent local resistance data but these data are scarce for the Austrian primary health care sector. Within the context of the ECO·SENS II study it was the aim to obtain appropriate and relevant local resistance data and describe the changes in the resistance pattern in comparison to the ECO·SENS study. Methods 23 GPs from different parts of Austria participated in the study between July 2007 and November 2008. According to the defined inclusion- and exclusion criteria female patients with symptoms of an uncomplicated UTI were included and a midstream urine sample was collected. In case of significant bacteriuria susceptibility testing of E. coli against 14 antibiotics was performed. Descriptive statistical methods were used. Results In 313 patients included in the study, a total of 147 E. coli isolates (47%) were detected and tested. The resistance rates were in %: Mecillinam (0.0), nitrofurantoin (0.7), fosfomycin trometamol (0.7), gentamycin (1.4), cefotaxime (2.7), ceftazidime (2.7), Cephadroxil (4.1) and ciprofloxacin (4.1). Higher resistance rates were found in amoxicillin/clavulanic acid (8.9), nalidixic acid (9.6), trimethoprim/sulphamethoxazole (14.4), trimethoprim (15.8), sulphamethoxazole (21.2) and ampicillin (28.8). Additionally, the comparison of these results with the results of the ECO·SENS study demonstrated an increase in resistance rates of ampicillin, amoxicillin/clavulanic acid, nalidixic acid and ciprofloxacin. Conclusions The resistance data for E. coli in uncomplicated UTIs in women gained by this study are the most recent data for this disease in Austria at the moment. The increased resistance rates of amoxicillin/clavulanic acid, ciprofloxacin and nalidixic acid should be respected when choosing an appropriate antibiotic for uncomplicated UTIs. The use of ampicillin, sulphamethoxazole, trimethoprim and trimethoprim/sulphametoxazole in uncomplicated UTIs in women should be questioned at all. The findings of this study should result in a regular surveillance system of resistances emerging in the ambulatory sector designed after the model of the EARS-Net. PMID:22989349

To study success and failure in the treatment of uncomplicated rhegmatogenous retinal detachments (RRDs). Nonrandomized, multicenter retrospective study. One hundred seventy-six surgeons from 48 countries spanning 5 continents provided information on the primary procedures for 7678 cases of RRDs including 4179 patients with uncomplicated RRDs. Reported data included specific clinical findings, the method of repair, and the outcome after intervention. Final failure of retinal detachment repair (level 1 failure rate), remaining silicone oil at the study's conclusion (level 2 failure rate), and need for additional procedures to repair the detachment (level 3 failure rate). Four thousand one hundred seventy-nine uncomplicated cases of RRD were included. Combining phakic, pseudophakic, and aphakic groups, those treated with scleral buckle alone (n = 1341) had a significantly lower final failure rate than those treated with vitrectomy, with or without a supplemental buckle (n = 2723; P = 0.04). In phakic patients, final failure rate was lower in the scleral buckle group compared with those who had vitrectomy, with or without a supplemental buckle (P = 0.028). In pseudophakic patients, the failure rate of the initial procedure was lower in the vitrectomy group compared with the scleral buckle group (P = 3×10(-8)). There was no statistically significant difference in failure rate between segmental (n = 721) and encircling (n = 351) buckles (P = 0.5). Those who underwent vitrectomy with a supplemental scleral buckle (n = 488) had an increased failure rate compared with those who underwent vitrectomy alone (n = 2235; P = 0.048). Pneumatic retinopexy was found to be comparable with scleral buckle when a retinal hole was present (P = 0.65), but not in cases with a flap tear (P = 0.034). In the treatment of uncomplicated phakic retinal detachments, repair using scleral buckle may be a good option. There was no significant difference between segmental versus 360-degree buckle. For pseudophakic uncomplicated retinal detachments, the surgeon should balance the risks and benefits of vitrectomy versus scleral buckle and keep in mind that the single-surgery reattachment rate may be higher with vitrectomy. However, if a vitrectomy is to be performed, these data suggest that a supplemental buckle is not helpful.

Lithium Poisoning.

Lithium is a commonly prescribed treatment for bipolar affective disorder. However, treatment is complicated by lithium's narrow therapeutic index and the influence of kidney function, both of which increase the risk of toxicity. Therefore, careful attention to dosing, monitoring, and titration is required. The cause of lithium poisoning influences treatment and 3 patterns are described: acute, acute-on-chronic, and chronic. Chronic poisoning is the most common etiology, is usually unintentional, and results from lithium intake exceeding elimination. This is most commonly due to impaired kidney function caused by volume depletion from lithium-induced nephrogenic diabetes insipidus or intercurrent illnesses and is also drug-induced. Lithium poisoning can affect multiple organs; however, the primary site of toxicity is the central nervous system and clinical manifestations vary from asymptomatic supratherapeutic drug concentrations to clinical toxicity such as confusion, ataxia, or seizures. Lithium poisoning has a low mortality rate; however, chronic lithium poisoning can require a prolonged hospital length of stay from impaired mobility and cognition and associated nosocomial complications. Persistent neurological deficits, in particular cerebellar, are described and the incidence and risk factors for its development are poorly understood, but it appears to be uncommon in uncomplicated acute poisoning. Lithium is readily dialyzable, and rationale support extracorporeal treatments to reduce the risk or the duration of toxicity in high-risk exposures. There is disagreement in the literature regarding factors that define patients most likely to benefit from treatments that enhance lithium elimination, including specific plasma lithium concentration thresholds. In the case of extracorporeal treatments, there are observational data in its favor, without evidence from randomized controlled trials (none have been performed), which may lead to conservative practices and potentially unnecessary interventions in some circumstances. More data are required to define the risk-benefit of extracorporeal treatments and their use (modality, duration) in the management of lithium poisoning.

To characterize the genetic diversity of Plasmodium falciparum (P. falciparum) field isolates in children from Lafia, North-central Nigeria, using the highly polymorphic P. falciparum merozoite surface protein 2 (MSP-2) gene as molecular marker. Three hundred and twenty children were enrolled into the study between 2005 and 2006. These included 140 children who presented with uncomplicated malaria at the Dalhatu Araf Specialist Hospital, Lafia and another 180 children from the study area with asymptomatic infection. DNA was extracted from blood spot on filter paper and MSP-2 genes were genotyped using allele-specific nested PCR in order to analyze the genetic diversity of parasite isolates. A total of 31 and 34 distinct MSP-2 alleles were identified in the asymptomatic and uncomplicated malaria groups respectively. No difference was found between the multiplicity of infection in the asymptomatic group and that of the uncomplicated malaria group (P>0.05). However, isolates of the FC27 allele type were dominant in the asymptomatic group whereas isolates of the 3D7 allele type were dominant in the uncomplicated malaria group. This study showed a high genetic diversity of P. falciparum isolates in North-central Nigeria and is comparable to reports from similar areas with high malaria transmission intensity.

In practice, nutrition recommendations vary widely for inpatient and discharge management of acute, uncomplicated diverticulitis. This systematic review aims to review the evidence and develop recommendations for dietary fibre modifications, either alone or alongside probiotics or antibiotics, versus any comparator in adults in any setting with or recently recovered from acute, uncomplicated diverticulitis. Intervention and observational studies in any language were located using four databases until March 2017. The Cochrane Risk of Bias tool and GRADE were used to evaluate the overall quality of the evidence and to develop recommendations. Eight studies were included. There was “very low” quality evidence for comparing a liberalised and restricted fibre diet for inpatient management to improve hospital length of stay, recovery, gastrointestinal symptoms and reoccurrence. There was “very low” quality of evidence for using a high dietary fibre diet as opposed to a standard or low dietary fibre diet following resolution of an acute episode, to improve reoccurrence and gastrointestinal symptoms. The results of this systematic review and GRADE assessment conditionally recommend the use of liberalised diets as opposed to dietary restrictions for adults with acute, uncomplicated diverticulitis. It also strongly recommends a high dietary fibre diet aligning with dietary guidelines, with or without dietary fibre supplementation, after the acute episode has resolved. PMID:29382074

Objective: To compare in a prospective, randomised, multicentre trial the relative merits of pre-discharge exercise ECG and early pharmacological stress echocardiography concerning risk stratification and costs of treating patients with uncomplicated acute myocardial infarction. Design: 262 patients from six participating centres with a recent uncomplicated myocardial infarction were randomly assigned to early (day 3–5) pharmacological stress echocardiography (n  =  132) or conventional pre-discharge (day 7–9) maximum symptom limited exercise ECG (n  =  130). Results: No complication occurred during either stress echocardiography or exercise ECG. At one year follow up there were 26 events (1 death, 5 non-fatal reinfarctions, 20 patients with unstable angina requiring hospitalisation) in patients randomly assigned to early stress echocardiography and 18 events (2 reinfarctions, 16 unstable angina requiring hospitalisation) in the group randomly assigned to exercise ECG (not significant). The negative predictive value was 92% for stress echocardiography and 88% for exercise ECG (not significant). Total costs of the two strategies were similar (not significant). Conclusion: Early pharmacological stress echocardiography and conventional pre-discharge symptom limited exercise ECG have similar clinical outcome and costs after uncomplicated infarction. Early pharmacological stress echocardiography should be considered a valid alternative even for patients with interpretable baseline ECG who can exercise. PMID:15657220

Appendectomy has remained the gold standard treatment of acute appendicitis for more than 100years. Nonoperative management (NOM) has been shown to be a valid treatment alternative for acute uncomplicated appendicitis in adults. A systematic review of available evidence comparing operative management (OM) and NOM in children with acute uncomplicated appendicitis was performed. Systematic searches of MedLine, Embase, and a clinical trial register (https://clinicaltrials.gov/) were performed in March 2016. Only articles that studied NOM for uncomplicated appendicitis in children were included. Data generation was performed independently by two authors, and quality was assessed using the rating schema by the Oxford Centre for Evidence-Based Medicine. 15 articles were selected: four retrospective analyses, four prospective cohort studies, four prospective nonrandomized comparative trials and one randomized controlled trial (RCT). Initial success of the NOM groups (a cure within two weeks of intervention) ranged from 58 to 100%, with 0.1-31.8% recurrence at one year. Although present literature is scarce, publications support the feasibility of further studies investigating NOM of acute uncomplicated appendicitis in children. Higher quality prospective RCTs with larger sample sizes and robust randomization methods, studying the noninferiority of NOM with antibiotics compared with OM are required to establish its utility. This manuscript is a systematic review and thus assigned the lowest evidence used from the manuscripts analyzed which is a Level IV. Copyright © 2017. Published by Elsevier Inc.

Urinary tract infections (UTIs) are among the most common bacterial infections in adult population. They are prevalent in all age groups both in women and men. Also, UTIs are the most frequent indication for empirical antibiotic treatment in emergency department. The aim of this study was to determine the antibiotic resistance rates in the treatment of uncomplicated UTIs. Adult patients admitted to emergency department with uncomplicated UTIs were included in this cross-sectional study. Mid-stream urine samples were obtained under sterile conditions and cultured quantitatively. After 24 hours, the samples showing 10(5) colony forming unit per milliliter (CFU/mL) were tested for antibiotic susceptibility. Resistance to fosfomycin-trometamol (FT), amoxicillin-clavulanic acid (AC), ciprofloxacin (CIP), trimethoprim-sulfamethoxazole (TMP-SMX) and cefpodoxime (CEF) was tested by Kirby-Bauer disc diffusion system. Escherichia (E.) coli accounted for the vast majority (93.4%) of the organisms isolated in the study. Among the E. coli positive patients, resistance to TMP-SMX was the most common antibiotic resistance. The E. coli species detected in our study group were least resistant to FT (2.4%). The resistance rates, especially to CEF, AC and CIP, were significantly higher in patients over 50 years of age. In conclusion, in the treatment of uncomplicated UTIs, TMP-SMX should be excluded from empirical treatment, while fosfomycin could be a viable option in all age groups.

To compare the effects of ketorolac 0.45% and diclofenac 0.1% on macular thickness and volume after uncomplicated cataract surgery. A total of 76 eyes of 76 patients who underwent uncomplicated cataract surgery were included. Patients were treated with either diclofenac 0.1% (38 eyes) or ketorolac 0.45% (38 eyes) after surgery. The macular thickness and volume were obtained with optical coherence tomography (OCT). Central subfield thickness (CST, OCT 1 mm zone), total foveal thickness (TFT, OCT 3 mm zone), total macular thickness (TMT, OCT 6 mm zone), average macular thickness (AMT) and total macular volume (TMV) were compared between the two study groups. No significant differences between groups were found in macular thickness or volume 1 month after cataract surgery. Two months after surgery, the ketorolac group had significantly lower CST, TFT, TMT and AMT than the diclofenac group (p < 0.05 for all). Additionally, 1 and 2 months after surgery, changes from preoperative values in CST (both p = 0.04), AMT (p = 0.02 and p < 0.01, respectively) and TMV (both p = 0.04) were significantly less in the ketorolac group than in the diclofenac group. Following uncomplicated cataract surgery, topical ketorolac 0.45% was more effective than diclofenac 0.1% in preventing increases in macular thickness and volume. © 2015 Acta Ophthalmologica Scandinavica Foundation.

Despite the widespread use and availability of rapidly acting anti-malarials, the fatality rate of severe malaria in sub-Saharan Africa remains high. Adjunctive therapies that target the host response to malaria infection may further decrease mortality over that of anti-malarial agents alone. Peroxisome proliferator-activated receptor-gamma agonists (e.g. rosiglitazone) have been shown to act on several pathways implicated in the pathogenesis of severe malaria and may improve clinical outcome as an adjunctive intervention. In this study, the safety and tolerability of adjunctive rosiglitazone in paediatric uncomplicated malaria infection was evaluated in Mozambique, as a prelude to its evaluation in a randomized controlled trial in paediatric severe malaria. The study was a prospective, randomized, double-blind, placebo-controlled, phase IIa trial of rosiglitazone (0.045 mg/kg/dose) twice daily for 4 days versus placebo as adjunctive treatment in addition to Mozambican standard of care (artemisinin combination therapy Coartem ® ) in children with uncomplicated malaria. The primary outcomes were tolerability and safety, including clinical, haematological, biochemical, and electrocardiographic evaluations. Thirty children were enrolled: 20 were assigned to rosiglitazone and 10 to placebo. Rosiglitazone treatment did not induce hypoglycaemia nor significantly alter clinical, biochemical, haematological, or electrocardiographic parameters. Adjunctive rosiglitazone was safe and well-tolerated in children with uncomplicated malaria, permitting the extension of its evaluation as adjunctive therapy for severe malaria. The trial is registered with Clinicaltrials.gov, NCT02694874.

Uncomplicated appendicitis may resolve spontaneously or require treatment with antibiotics or appendicectomy. The aim of this randomized trial was to compare the outcome of a non-antibiotic management strategy with that of antibiotic therapy in uncomplicated appendicitis. Patients presenting to a university teaching hospital with CT-verified uncomplicated simple appendicitis (appendiceal diameter no larger than 11 mm and without any signs of perforation) were randomized to management with a no-antibiotic regimen with supportive care (intravenous fluids, analgesia and antipyretics as necessary) or a 4-day course of antibiotics with supportive care. The primary endpoint was rate of total treatment failure, defined as initial treatment failure within 1 month and recurrence of appendicitis during the follow-up period. Some 245 patients were randomized within the trial, and followed up for a median of 19 months. The duration of hospital stay was shorter (mean 3·1 versus 3·7 days; P < 0·001) and the medical costs lower (€1181 versus 1348; P < 0·001) among those randomized to therapy without antibiotics. There was no difference in total treatment failure rate between the groups: 29 of 124 (23·4 per cent) in the no-antibiotic group and 25 of 121 (20·7 per cent) in the antibiotic group (P = 0·609). Eighteen patients (9 in each group) had initial treatment failure, 15 of whom underwent appendicectomy and three received additional antibiotics. Thirty-six patients (20 in the no-antibiotic group, 16 in the antibiotic group) experienced recurrence, of whom 30 underwent appendicectomy and six received further antibiotics. Treatment failure rates in patients presenting with CT-confirmed uncomplicated appendicitis appeared similar among those receiving supportive care with either a no-antibiotic regimen or a 4-day course of antibiotics.

Most studies during pregnancy have assessed maternal left ventricular (LV) function by load-dependent indices, assessing only chamber function. The aim of this study was to assess afterload-adjusted LV myocardial and chamber systolic function at 24 weeks' gestation and 6 months postpartum in high-risk normotensive pregnant women. A group of 118 high-risk women with bilateral notching of the uterine arteries underwent an echocardiographic examination to evaluate midwall mechanics (midwall shortening (mFS%) and stress-corrected midwall shortening (SCmFS%)) of the LV at 24 weeks' gestation and 6 months postpartum. Patients were followed until delivery and pregnancies were classified retrospectively as uneventful (uncomplicated outcome) or complicated. A control group of 54 low-risk women with uneventful pregnancies without bilateral notching was also enrolled. The pregnancy was uneventful in 74 (62.7%) women, whereas 44 (37.3%) developed complications. At 24 weeks' gestation, mFS% and SCmFS% were greater in the uncomplicated-outcome compared with the complicated-outcome group (25.9 ± 4.8 vs 18.8 ± 5.0%, P < 0.001 and 107.9 ± 18.4 vs 77.9 ± 20.7%, P < 0.001, respectively). At 6 months postpartum, SCmFS% remained greater in the uncomplicated-outcome compared with the complicated-outcome group (100.4 ± 21.6 vs 87.8 ± 19.1, P < 0.05). In the uncomplicated-outcome group, SCmFS% was higher during pregnancy than it was postpartum, whereas in the complicated-outcome group, it was lower during pregnancy than it was postpartum (P < 0.05). Maternal cardiac midwall mechanics appear to be enhanced (SCmFS% increased compared with controls) during pregnancy compared with postpartum in high-risk patients with uncomplicated pregnancy, whereas midwall mechanics are depressed both during pregnancy and postpartum in patients with pregnancy complications.

Uncomplicated urinary tract infections (UTI) are common in general practice, and are usually treated with antibiotics. Recurrent UTI often pose a serious problem for affected women. Little is known about recurrent UTI and complications when uncomplicated UTI are treated without antibiotics. With ICUTI (Immediate vs. conditional antibiotic use in uncomplicated UTI, funded by BMBF No. 01KG1105) we assessed whether initial symptomatic treatment with ibuprofen could be a treatment alternative for uncomplicated UTI. The presented analysis aims to assess the influence of initial (non-)antibiotic treatment on recurrent UTI rates and pyelonephritis after day 28 up to 6 months after trial participation. This study is a retrospective long-term follow-up analysis of ICUTI patients, surveyed telephonically six months after inclusion in the trial. Recurrent UTI, pyelonephritis or hospitalizations were documented. Statistical evaluation was performed by descriptive and multivariate analyses with SPSS 21. For the six months follow-up survey, 386 trial participants could be contacted (494 had been included in ICUTI initially, 446 had completed the trial). From day 28 until 6 months after inclusion in ICUTI, 84 recurrent UTI were reported by 80 patients. Univariate and multivariate analyses showed no effect of initial treatment group or antibiotic treatment on number of patients with recurrent UTI. Yet, both analyses showed that patients with a history of previous UTI had significantly more often recurrent UTI. Pyelonephritis occurred in two patients of the antibiotic group and in one patient in the non-antibiotic group. This follow-up analysis of a trial comparing antibiotic vs. symptomatic treatment for uncomplicated UTI showed that non-antibiotic treatment has no negative impact on recurrent UTI rates or pyelonephritis after day 28 and up to six months after initial treatment. Thus, a four week follow-up in UTI trials seems adequate.

Research suggest that post-concussive syndrome after mild traumatic brain injury (mTBI) is more common than chronic cognitive impairment. The aim of this study was to investigate very long-term outcome of subjective complaints after paediatric mTBI. The study was a follow-up 23 years after a prospective head injury study at a general hospital in Norway. Forty-one patients were assessed with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) 23 years after sustaining mTBI as children. A good overall outcome was found with scores close to the normative mean, average length of education and normal employment rate. However, the children that sustained complicated mTBI showed slightly more pathological scores, typical for mild post-concussive syndrome. The most important predictors of poor outcome were skull fracture and a combination of post-traumatic amnesia > 30 minutes and EEG pathology within 24 hours after TBI. No influence of pre- and post-injury risk factors on current MMPI-2 profiles was evident. The results give support for the notion of potentially differential impact of uncomplicated vs complicated mTBI. The findings suggest that children and adolescents sustaining complicated mTBI may be at risk of developing subtle chronic symptoms typical of post-concussive syndrome.

Background/Aims Most patients with acute viral hepatitis A have a favorable course, but a few of them suffer from severe forms of hepatitis such as fulminant hepatitis. This study was carried out to identify the factors influencing the severity of acute viral hepatitis A. Methods We retrospectively reviewed the medical records of 713 patients with acute hepatitis A, who were divided into two groups: severe hepatitis A (N=87) and non-severe hepatitis A (N=626). Severe hepatitis was defined as fulminant hepatitis or prolongation of prothrombin time (INR≥1.5). Clinical variables were compared between the two groups. Results The incidence of fulminant hepatitis was 1.4% (10/713) in patients with acute hepatitis A. Thirty-three (4.6%) cases exhibited HBsAg positivity. In multivariate analyses, significant alcohol intake and the presence of HBsAg were significant predictive factors of fulminant hepatitis A, and significant alcohol intake and age were significant predictive factors of severe hepatitis A. HBeAg and HBV-DNA status did not affect the clinical course of hepatitis A in chronic hepatitis B carriers. Conclusions While most patients with acute hepatitis A have an uncomplicated clinical course, our data suggest that a more-severe clinical course is correlated with being older, significant alcohol intake, and chronic hepatitis-B-virus infection.

Acute uncomplicated urinary tract infection (UTI) is a common clinical problem, accounting for millions of outpatient visits in the USA annually. Although routinely obtaining urine cultures in UTI is not recommended, there are circumstances in which obtaining a pre-therapy culture may be warranted or chosen by clinicians, such as when indicated by the need for careful antimicrobial stewardship. This review focuses on understanding reasons for obtaining a pre-therapy culture, methods of collection, and appropriately interpreting urine culture data.

An increasing amount of evidence supports the use of antibiotics instead of surgery for treating patients with uncomplicated acute appendicitis. To compare antibiotic therapy with appendectomy in the treatment of uncomplicated acute appendicitis confirmed by computed tomography (CT). The Appendicitis Acuta (APPAC) multicenter, open-label, noninferiority randomized clinical trial was conducted from November 2009 until June 2012 in Finland. The trial enrolled 530 patients aged 18 to 60 years with uncomplicated acute appendicitis confirmed by a CT scan. Patients were randomly assigned to early appendectomy or antibiotic treatment with a 1-year follow-up period. Patients randomized to antibiotic therapy received intravenous ertapenem (1 g/d) for 3 days followed by 7 days of oral levofloxacin (500 mg once daily) and metronidazole (500 mg 3 times per day). Patients randomized to the surgical treatment group were assigned to undergo standard open appendectomy. The primary end point for the surgical intervention was the successful completion of an appendectomy. The primary end point for antibiotic-treated patients was discharge from the hospital without the need for surgery and no recurrent appendicitis during a 1-year follow-up period. There were 273 patients in the surgical group and 257 in the antibiotic group. Of 273 patients in the surgical group, all but 1 underwent successful appendectomy, resulting in a success rate of 99.6% (95% CI, 98.0% to 100.0%). In the antibiotic group, 70 patients (27.3%; 95% CI, 22.0% to 33.2%) underwent appendectomy within 1 year of initial presentation for appendicitis. Of the 256 patients available for follow-up in the antibiotic group, 186 (72.7%; 95% CI, 66.8% to 78.0%) did not require surgery. The intention-to-treat analysis yielded a difference in treatment efficacy between groups of -27.0% (95% CI, -31.6% to ∞) (P = .89). Given the prespecified noninferiority margin of 24%, we were unable to demonstrate noninferiority of antibiotic treatment relative to surgery. Of the 70 patients randomized to antibiotic treatment who subsequently underwent appendectomy, 58 (82.9%; 95% CI, 72.0% to 90.8%) had uncomplicated appendicitis, 7 (10.0%; 95% CI, 4.1% to 19.5%) had complicated acute appendicitis, and 5 (7.1%; 95% CI, 2.4% to 15.9%) did not have appendicitis but received appendectomy for suspected recurrence. There were no intra-abdominal abscesses or other major complications associated with delayed appendectomy in patients randomized to antibiotic treatment. Among patients with CT-proven, uncomplicated appendicitis, antibiotic treatment did not meet the prespecified criterion for noninferiority compared with appendectomy. Most patients randomized to antibiotic treatment for uncomplicated appendicitis did not require appendectomy during the 1-year follow-up period, and those who required appendectomy did not experience significant complications. clinicaltrials.gov Identifier: NCT01022567.

Acute appendicitis is the most common surgical emergency. The aim of this study was to evaluate the clinical results of laparoscopic appendectomy (LA) for the treatment of uncomplicated and complicated appendicitis. A retrospective analysis was performed who had undergone laparoscopic appendectomy for complicated appendicitis between January 2010 to October 2013. The diagnosis of acute appendicitis was established with physical examination, laboratory tests, and ultrasound examination. The patients were analysed for age, sex, conversion rate,operation time, postoperative infectious complications and length of hospital stay. A total of 452 patients were operated with LA. There were 362 (80.1%) uncomplicated (Group I) and 90 (19.1%) complicated Group (II) appendicitis.The intraabdominal abscess rate was 14.35% in Group I and 19.5% in Group II. The wound infection and rate of incisional hernia were also higher in Group II. The postoperative complications including intraabdominal abscess, wound infection and incisional hernia after LA in complicated appendicitis found high. LA should be performed very carefully in complicated appendicitis. PMID:25419386

The efficacy and safety of artemether-lumefantrine for the treatment of malaria in nonimmune populations are not well defined. In this study, 165 nonimmune patients from Europe and non-malarious areas of Colombia with acute, uncomplicated falciparum malaria or mixed infection including P. falciparum were treated with the six-dose regimen of artemether-lumefantrine. The parasitologic cure rate at 28 days was 96.0% for the per protocol population (119/124 patients). Median times to parasite clearance and fever clearance were 41.5 and 36.8 hours, respectively. No patient had gametocytes after Day 7. Treatment was well tolerated; most adverse events were mild to moderate and seemed to be related to malaria. There were few serious adverse events, none of which were considered to be drug-related. No significant effects on ECG or laboratory parameters were observed. In conclusion, the six-dose regimen of artemether-lumefantrine was effective and well tolerated in the treatment of acute uncomplicated falciparum malaria in nonimmune patients.

Artemisinin-based combination therapies (ACTs) are the first-line treatment of uncomplicated malaria. The public health benefit and safety of repeated administration of a given ACT are poorly studied. We conducted a randomized trial comparing artemether-lumefantrine, artesunate plus amodiaquine (AS+AQ) and artesunate plus sulfadoxine-pyrimethamine (AS+SP) in patients 6 months of age and older with uncomplicated malaria in Mali from July 2005 to July 2007. The patient received the same initial treatment of each subsequent uncomplicated malaria episode except for treatment failures where quinine was used. Overall, 780 patients were included. Patients in the AS+AQ and AS+SP arms had significantly less risk of having malaria episodes; risk ratio (RR) = 0.84 (P = 0.002) and RR = 0.80 (P = 0.001), respectively. The treatment efficacy was similar and above 95% in all arms. Although all drugs were highly efficacious and well tolerated, AS+AQ and AS+SP were associated with less episodes of malaria.

The aim of this study was to evaluate whether pregnant women with fetal growth restriction (FGR) have higher plasma neopterin and C-reactive protein (CRP) concentrations compared with those with uncomplicated pregnancy. A total of 34 pregnant women with FGR and 62 patients with uncomplicated pregnancy were included. Neopterin and CRP levels were measured at the time of diagnosis. The primary outcome of this study was to compare the neopterin and CRP levels in pregnant women with FGR and those with uncomplicated pregnancies. The secondary outcome of our study was to evaluate the correlation between fetal birth weight and maternal neopterin levels. The serum neopterin levels were significantly elevated in pregnant women with FGR (22.71 ± 7.70 vs 19.15 ± 8.32). However, CRP was not elevated in pregnant women with FGR (7.47 ± 7.59 vs 5.29 ± 3.58). These findings support the hypothesis that pregnancy with FGR is associated with a marked increase in macrophage activation and the natural immune system.

To determine perinatal outcomes in uncomplicated term pregnancies with a borderline amniotic fluid index (AFI). A retrospective review was conducted of uncomplicated singleton pregnancies at term (>37 weeks). Borderline and normal AFI were defined as 5.1 ≤ AFI ≤ 8.0 cm and 8.1 ≤ AFI ≤ 24 cm, respectively. Adverse perinatal outcomes, cesarean delivery for non-reassuring fetal heart rate testing, meconium-stained amniotic fluid, a 5-min Apgar score of <7, admission to the neonatal intensive care unit (NICU), and whether the neonate was small for gestational age were compared between the borderline and normal AFI groups. Borderline AFI was not significantly associated with cesarean delivery for non-reassuring fetal heart rate testing (p = 0.513), meconium-stained amniotic fluid (p = 0.641), admission to the NICU (p = 0.368), or a 5-min Apgar score of <7 (p = 1.00). However, the number of neonates who were small for gestational age (p = 0.021) and rates of induction of labor (p < 0.001) were significantly higher in the borderline group. Multiple logistic regression analysis showed that borderline AFI was not associated with cesarean delivery for non-reassuring fetal heart rate testing (odds ratio [OR] = 0.72, 95% confidence interval [CI] 0.27-1.91, p = 0.52). In uncomplicated term pregnancies, a borderline AFI does not increase the risk of adverse perinatal outcomes.

The purpose of this study is to determine the adverse perinatal outcomes in uncomplicated late preterm pregnancies with borderline oligohydramnios. A total of 430 pregnant women with an uncomplicated singleton pregnancy at a gestational age of 34 + 0-36 + 6 weeks were included. Borderline oligohydramnios was defined as an amniotic fluid index (AFI) of 5.1-8 cm, which was measured using the four-quadrant technique. Adverse perinatal outcomes were compared between the borderline and normal AFI groups. Approximately 107 of the 430 pregnant women were borderline AFI, and 323 were normal AFI. The demographic and obstetric characteristics were similar in both groups. Delivery <37 weeks, cesarean delivery for non-reassuring fetal heart-rate testing, meconium-stained amniotic fluid, Apgar 5 min <7, transient tachypnea of the newborn, respiratory distress syndrome, neonatal intensive care unit, and hyperbilirubinemia were not statistically different between the groups (p = .054, p = .134, p = .749, p = 0.858, p = .703, p = .320, p = .185, and p = .996, respectively). Although gestational age was full-term, induction of labor rates were significantly higher in the borderline AFI group (p = .040). In addition, fetal renal artery pulsatility index pulsatility index (PI) was significantly lower in the borderline AFI group than in the normal AFI group (p = .014). Our results indicated that borderline AFI was not a risk for adverse perinatal outcomes in uncomplicated, late preterm pregnancies.

A retrospective study was conducted to provide epidemiological data on hospitalization for complicated and uncomplicated chickenpox in a pediatric population. The study analyzed hospitalization cases for chickenpox, among all the 31 Tuscan hospitals, during the period 1997-2003. Globally, 650 cases were recorded (306 = 47.07% for uncomplicated and 344 = 52.92% for complicated chickenpox). Total hospitalization rate was 22.66 per 100,000 living Tuscan children and 11.52 per 1,000 notified chickenpox cases. Hospitalization rates for complicated chickenpox were 12.00 per 100,000 living children and 6.09 per 1,000 notified cases. Notably, significantly increased hospitalization rates for complicated chickenpox were evidenced over years (p = 0.011 per 100,000 living children and p = 0.001 per 1,000 notified cases), due to the increased proportion of neurological (p = 0.043 per 100,000 living children and p = 0.025 per 1,000 notified cases) and respiratory (p = 0.021 per 100,000 living children and p = 0.008 per 1,000 notified cases) complications, whereas hospitalization rates for other complications as well as for uncomplicated chickenpox remained constant (p = 0.25 per 100,000 living children and p = 0.09 per 1,000 notified cases). Chickenpox complications, requiring hospitalization, occurred at a substantial rate in our pediatric population. In particular, increasing hospitalization rates for neurological and respiratory complications were evidenced over the study period. Our epidemiological data may provide additional information while planning a vaccination strategy for Italy.

To identify preinjury coping profiles among adults with uncomplicated mild traumatic brain injury (mTBI) and complicated mTBI and to determine whether preinjury coping profiles contribute to the prediction of emotional functioning and quality of life (QOL) 3 months post-mTBI. One hundred eighty-seven persons with medically documented mTBI (uncomplicated mTBI, n = 89; complicated mTBI, n = 98) were recruited from the emergency center of a level I trauma center and followed in community 3 months post-mTBI. The Ways of Coping Questionnaire was administered within 2 weeks of injury. Cluster analysis was used to group participants on basis of their preinjury use of problem-focused and avoidant coping strategies. The Brief Symptom Inventory and the 36-item Short-Form Health Survey were administered 3 months postinjury. Cluster analysis distinguished 3 distinct preinjury coping profiles that were differentially associated with outcomes. Participants who used avoidant coping showed the worse emotional functioning and QOL outcomes, although this cluster also reported high usage of problem-focused strategies. Preinjury coping profiles explained a significant proportion of the variance in depression, anxiety, and mental health QOL at 3 months postinjury beyond that accounted for by demographic characteristics and mTBI severity. Cluster analysis holds practical value in illustrating the pattern of coping strategies used by person with uncomplicated and complicated mTBI. It appears worthwhile to address coping in future trials of interventions that are aimed at improving emotional functioning after mTBI.

In Colombia, there are no published studies for the treatment of uncomplicated Plasmodium falciparum malaria comparing artemisinin combination therapies. Hence, it is intended to demonstrate the non-inferior efficacy/safety profiles of artesunate + amodiaquine versus artemether-lumefantrine treatments. A randomized, controlled, open-label, noninferiority (Δ≤5%) clinical trial was performed in adults with uncomplicated P. falciparum malaria using the 28-day World Health Organization validated design/definitions. Patients were randomized 1:1 to either oral artesunate + amodiaquine or artemether-lumefantrine. The primary efficacy endpoint: adequate clinical and parasitological response; secondary endpoints: - treatment failures defined per the World Health Organization. assessed through adverse events. A total of 105 patients was included in each group: zero censored observations. Mean (95%CI - Confidence interval) adequate clinical and parasitological response rates: 100% for artesunate + amodiaquine and 99% for artemether-lumefantrine; the noninferiority criteria was met (Δ=1.7%). There was one late parasitological therapeutic failure (1%; artemether-lumefantrine group), typified by polymerase chain reaction as the MAD20 MSP1 allele. The fever clearance time (artesunate + amodiaquine group) was significantly shorter (p=0.002). Respectively, abdominal pain for artesunate + amodiaquine and artemether-lumefantrine was 1.9% and 3.8% at baseline (p=0.68) and 1% and 13.3% after treatment (p<0.001). Uncomplicated P. falciparum malaria treatment with artesunate + amodiaquine is noninferior to the artemether-lumefantrine standard treatment. The efficacy/safety profiles grant further studies in this and similar populations.

The clinical manifestations of urinary infections, commonly mild and uncomplicated, have resulted in a generally empirical therapeutic decision-making process, which does not help fight resistances to antibacterial agents, thus causing a high rate of recurrence. This study seeks to reduce the clinical variability in the diagnosis and treatment of uncomplicated recurrent urinary tract infections (RUTIs). The consensus document was developed using a nominal group methodology, using scientific evidence on RUTIs extracted from a systematic (noncomprehensive) literature review, along with the expert judgment of specialists and their experience in clinical practice. RUTIs are considered the manifestation of at least 3 episodes of uncomplicated infection, with a positive culture in the past 12 months, in addition to (for men) the absence of structural or functional abnormalities. We maintain that the treatment should be empiric when suspecting RUTIs (prior to obtaining a urine sample for culture) in those patients who have a high probability of recurrence, associated risk factors and/or urinary or general symptoms, such as fever and chills. Homogeneous criteria are recommended for the diagnosis and treatment in order to fight the increased rates of resistance that the microorganisms develop against antimicrobial agents. Imprecision in the identification of the infection requires a search for agreements on homogenized criteria and decision algorithms that guide the management of these patients. Copyright © 2014 AEU.

The optimal diet for uncomplicated diverticulitis is unclear. Guidelines refrain from recommendation due to lack of objective information. The aim of the study was to determine whether an unrestricted diet during a first acute episode of uncomplicated diverticulitis is safe. A prospective cohort study was performed of patients diagnosed with diverticulitis for the first time between 2012 and 2014. Requirements for inclusion were radiologically proven modified Hinchey Ia/b diverticulitis, American Society of Anesthesiologists class I-III and the ability to tolerate an unrestricted diet. Exclusion criteria were the use of antibiotics and suspicion of inflammatory bowel disease or malignancy. All included patients were advised to take an unrestricted diet. The primary outcome parameter was morbidity. Secondary outcome measures were the development of recurrence and ongoing symptoms. There were 86 patients including 37 (43.0%) men. All patients were confirmed to have taken an unrestricted diet. There were nine adverse events in seven patients. These consisted of readmission for pain (five), recurrent diverticulitis (one) and surgery (three) for ongoing symptoms (two) and Hinchey Stage III (one). Seventeen (19.8%) patients experienced continuing symptoms 6 months after the initial episode and 4 (4.7%) experienced recurrent diverticulitis. The incidence of complications among patients taking an unrestricted diet during an initial acute uncomplicated episode of diverticulitis was in line with that reported in the literature.

Acute appendicitis is the most common surgical diagnosis in young patients, with lifetime prevalence of about 7%. Debate remains on whether uncomplicated AA should be operated or not. Aim of this meta-analysis of randomized controlled trials was to assess current evidence on antibiotic treatment for uncomplicated AA compared to standard surgical treatment. Systematic literature search was performed using PubMed, EMBASE, Medline, Google Scholar and Cochrane Central Register of Controlled Trials databases for randomized controlled trials comparing antibiotic therapy (AT) and surgical therapy-appendectomy (ST) for uncomplicated AA. Trials were reviewed for primary outcome measures: treatment efficacy based on 1 year follow-up, recurrence at 1 year follow-up, complicated appendicitis with peritonitis identified at the time of surgical operation and post-intervention complications. Secondary outcomes were length of hospital stay and period of sick leave. Five RCTs comparing AT and ST qualified for inclusion in meta-analysis, with 1.351 patients included: 632 in AT group and 719 in ST group. Higher rate of treatment efficacy based on 1 year follow-up was found in ST group (98.3% vs 75.9%, P < 0.0001), recurrence at 1 year was reported in 22.5% of patients treated with antibiotics. Rate of complicated appendicitis with peritonitis identified at time of surgical operation was higher in AT group (19.9% vs 8.5%, P = 0.02). No statistically significant differences were found when comparing AT and ST groups for the outcomes of overall post-intervention complications (4.3% vs 10.9%, P = 0.32), post-intervention complications based on the number of patients who underwent appendectomy (15.8% vs 10.9%, P = 0.35), length of hospital stay (3.24 ± 0.40 vs 2.88 ± 0.39, P = 0.13) and period of sick leave (8.91 ± 1.28 vs 10.27 ± 0.24, P = 0.06). With significantly higher efficacy and low complication rates, appendectomy remains the most effective treatment for patients with uncomplicated AA. The subgroups of patients with uncomplicated AA where antibiotics can be more effective, should be accurately identified.

Alagha, Babak

2015-10-01

Acute and chronic spinal symptoms such as neck pain may limit flying performance significantly and disqualify the pilot from flight duty. Mechanical neck pain is very common among pilots because of their exposure to vibration, +GZ forces, helmet weight, poor neck posture during air combat maneuvers, previous neck injuries, and poor treatment plans for such injuries. Successful treatment of such injuries requires appropriate therapeutic procedures as well as an aeromedical assessment. The aim of this case study was to demonstrate the benefits of conservative procedures such as spinal manipulation and mobilization therapy (SMMT) and exercise therapy (ET) in treating chronic mechanical neck pain in an Iranian commercial helicopter pilot. A 36-yr-old male patient presented to the clinic with moderate, intermittent nonradicular chronic neck pain and limited range of motion over a 2-yr period. The patient was treated with cervical and upper thoracic SMMT followed by home ET for 5 wk. After this period, the patient reported significant recovery and improvement in range of motion in his neck. Mechanical neck pain is very common among helicopter pilots. Although Air Force and Navy waiver guides recommend nonsteroidal anti-inflammatory medications as well as SMMT and ET, there are currently very few published studies that examine the benefits of manual and exercise therapy for treating mechanical neck pain in commercial and military pilots. Based on the results of this study, it seems that SMMT and ET may be a safe and effective in treatment of uncomplicated mechanical neck pain in helicopter pilots. Alagha B.

To characterize a model of atypical antipsychotic drug-induced obesity and evaluate its mechanism. Chronically, olanzapine or clozapine was self-administered via cookie dough to rodents (Sprague-Dawley or Wistar rats; C57Bl/6J or A/J mice). Chronic studies measured food intake, body weight, adiponectin, active ghrelin, leptin, insulin, tissue wet weights, glucose, clinical chemistry endpoints, and brain dopaminergic D2 receptor density. Acute studies examined food intake, ghrelin, leptin, and glucose tolerance. Olanzapine (1 to 8 mg/kg), but not clozapine, increased body weight in female rats only. Weight changes were detectable within 2 to 3 days and were associated with hyperphagia starting approximately 24 hours after the first dose. Chronic administration (12 to 29 days) led to adiposity, hyperleptinemia, and mild insulin resistance; no lipid abnormalities or changes in D2 receptor density were observed. Topiramate, which has reversed weight gain from atypical antipsychotics in humans, attenuated weight gain in rats. Acutely, olanzapine, but not clozapine, lowered plasma glucose and leptin. Increases in glucose, insulin, and leptin following a glucose challenge were also blunted. A model of olanzapine-induced obesity was characterized which shares characteristics of patients with atypical antipsychotic drug-induced obesity; these characteristics include hyperphagia, hyperleptinemia, insulin resistance, and weight gain attenuation by topiramate. This model may be a useful and inexpensive model of uncomplicated obesity amenable to rapid screening of weight loss drugs. Olanzapine-induced weight gain may be secondary to hyperphagia associated with acute lowering of plasma glucose and leptin, as well as the inability to increase plasma glucose and leptin following a glucose challenge.

Abstract Objective: Endocan, a dermatan sulphate proteoglycan produced by endothelial cells, is considered a biomarker for endothelial cell activation/dysfunction. Preeclampsia is characterized by systemic vascular inflammation, and endothelial cell activation/dysfunction. Therefore, the objectives of this study were to determine whether: (1) plasma endocan concentrations in preeclampsia differ from those in uncomplicated pregnancies; (2) changes in plasma endocan concentration relate to the severity of preeclampsia, and whether these changes are specific or observed in other obstetrical syndromes such as small-for-gestational age (SGA), fetal death (FD), preterm labor (PTL) or preterm prelabor rupture of membranes (PROM); (3) a correlation exists between plasma concentration of endocan and angiogenic (placental growth factor or PlGF)/anti-angiogenic factors (soluble vascular endothelial growth factor receptor or sVEGFR-1, and soluble endoglin or sEng) among pregnancies complicated by preeclampsia; and (4) plasma endocan concentrations in patients with preeclampsia and acute pyelonephritis (both conditions in which there is endothelial cell activation) differ. Method: This cross-sectional study included the following groups: (1) uncomplicated pregnancy (n = 130); (2) preeclampsia (n = 102); (3) pregnant women without preeclampsia who delivered an SGA neonate (n = 51); (4) FD (n = 49); (5) acute pyelonephritis (AP; n = 35); (6) spontaneous PTL (n = 75); and (7) preterm PROM (n = 64). Plasma endocan concentrations were determined in all groups, and PIGF, sEng and VEGFR-1 plasma concentrations were measured by ELISA in the preeclampsia group. Results: (1) Women with preeclampsia had a significantly higher median plasma endocan concentration than those with uncomplicated pregnancies (p = 0.004); (2) among women with preeclampsia, the median plasma endocan concentration did not differ significantly according to disease severity (p = 0.1), abnormal uterine artery Doppler velocimetry (p = 0.7) or whether diagnosis was made before or after 34 weeks gestational age (p = 0.3); (3) plasma endocan concentration in women with preeclampsia correlated positively with plasma anti-angiogenic factor concentrations [sVEGFR-1: Spearman rho 0.34, p = 0.001 and sEng: Spearman rho 0.30, p = 0.003]; (4) pregnancies complicated by acute pyelonephritis with bacteremia had a lower median plasma endocan concentration than pregnancies complicated by acute pyelonephritis without bacteremia (p = 0.004), as well as uncomplicated pregnancies (p = 0.001); and (5) there was no significant difference in the median plasma endocan concentration between uncomplicated pregnancies and those complicated by FD, delivery of an SGA neonate, PTL or preterm PROM (other members of the “great obstetrical syndromes”; each p > 0.05). Conclusion: Median maternal plasma endocan concentrations were higher preeclampsia and lower in acute pyelonephritis with bacteremia than in uncomplicated pregnancy. No significant difference was observed in the median plasma endocan concentration between other great obstetrical syndromes and uncomplicated pregnancies. The difference in the direction of change of endocan in preeclampsia and acute pyelonephritis with bacteremia may be consistent with the view that both disease entities differ in pathogenic mechanisms, despite their associations with systemic vascular inflammation and endothelial cell activation/dysfunction.

Objective Pregnancy is characterized by activation of the innate immune response demonstrated by phenotypic and metabolic changes in granulocytes and monocytes. This state of activation has been implicated in the pathophysiology of multiorgan dysfunction of pregnant women with acute viral or bacterial infection. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is one of the mediators responsible for neutrophil apoptosis. Gene deletion of TRAIL results in delayed neutrophil apoptosis and resolution of inflammation after the administration of bacterial endotoxin. The aim of this study was to determine if maternal plasma concentrations of the soluble form of TRAIL (sTRAIL) differ in women with uncomplicated pregnancy and those with acute pyelonephritis. Method A cross-sectional study was conducted to include women in the following groups: 1) non-pregnant (n=23); 2) uncomplicated pregnancies (n=93); and 3) pregnancies with acute pyelonephritis (n=23). Plasma concentrations of sTRAIL were determined by ELISA. Results 1) Women with uncomplicated pregnancies had a lower mean plasma sTRAIL concentration (pg/mL) than non-pregnant women (31.5 ± 10.1 vs. 53.3 ± 12.5; p < 0.001); 2) plasma sTRAIL concentrations did not change as a function of gestational age (Pearson correlation = −0.1; p=0.4); 3) the mean plasma sTRAIL concentration (pg/mL) was significantly lower in pregnant women with acute pyelonephritis than in those with uncomplicated pregnancies (20.5 ± 6.6 vs. 31.5 ± 10.1; p<0.001); and 4) among patients with acute pyelonephritis, patients with bacteremia had a significantly lower mean plasma concentration of sTRAIL (pg/mL) than those without bacteremia (15.1 ± 4.8 vs. 24.7 ± 4.6; p< 0.001). Conclusion Women with uncomplicated pregnancies are associated with a significantly lower mean maternal plasma concentration of sTRAIL than that observed in non-pregnant women. Moreover, a further decrease of plasma sTRAIL concentration was observed in pregnant women with acute pyelonephritis, and this could account, at least in part, for the exaggerated intravascular inflammatory response previously reported in pyelonephritis during pregnancy.

An increasing amount of evidence supports antibiotic therapy for treating uncomplicated acute appendicitis. The objective of this study was to compare the costs of antibiotics alone versus appendicectomy in treating uncomplicated acute appendicitis within the randomized controlled APPAC (APPendicitis ACuta) trial. The APPAC multicentre, non-inferiority RCT was conducted on patients with CT-confirmed uncomplicated acute appendicitis. Patients were assigned randomly to appendicectomy or antibiotic treatment. All costs were recorded, whether generated by the initial visit and subsequent treatment or possible recurrent appendicitis during the 1-year follow-up. The cost estimates were based on cost levels for the year 2012. Some 273 patients were assigned to the appendicectomy group and 257 to antibiotic treatment. Most patients randomized to antibiotic treatment did not require appendicectomy during the 1-year follow-up. In the operative group, overall societal costs (€5989·2, 95 per cent c.i. 5787·3 to 6191·1) were 1·6 times higher (€2244·8, 1940·5 to 2549·1) than those in the antibiotic group (€3744·4, 3514·6 to 3974·2). In both groups, productivity losses represented a slightly higher proportion of overall societal costs than all treatment costs together, with diagnostics and medicines having a minor role. Those in the operative group were prescribed significantly more sick leave than those in the antibiotic group (mean(s.d.) 17·0(8·3) (95 per cent c.i. 16·0 to 18·0) versus 9·2(6·9) (8·3 to 10·0) days respectively; P < 0·001). When the age and sex of the patient as well as the hospital were controlled for simultaneously, the operative treatment generated significantly more costs in all models. Patients receiving antibiotic therapy for uncomplicated appendicitis incurred lower costs than those who had surgery. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

Objective To evaluate adherence to uncomplicated urinary tract infections (UTI) guidelines and UTI diagnostic accuracy in an emergency department (ED) setting before and after implementation of an antimicrobial stewardship intervention. Methods The intervention included implementation of an electronic UTI order set followed by a 2 month period of audit and feedback. For women age 18 – 65 with a UTI diagnosis seen in the ED with no structural or functional abnormalities of the urinary system, we evaluated adherence to guidelines, antimicrobial use, and diagnostic accuracy at baseline, after implementation of the order set (period 1), and after audit and feedback (period 2). Results Adherence to UTI guidelines increased from 44% (baseline) to 68% (period 1) to 82% (period 2) (P≤.015 for each successive period). Prescription of fluoroquinolones for uncomplicated cystitis decreased from 44% (baseline) to 14% (period 1) to 13% (period 2) (P<.001 and P = .7 for each successive period). Unnecessary antibiotic days for the 200 patients evaluated in each period decreased from 250 days to 119 days to 52 days (P<.001 for each successive period). For 40% to 42% of cases diagnosed as UTI by clinicians, the diagnosis was deemed unlikely or rejected with no difference between the baseline and intervention periods. Conclusions A stewardship intervention including an electronic order set and audit and feedback was associated with increased adherence to uncomplicated UTI guidelines and reductions in unnecessary antibiotic therapy and fluoroquinolone therapy for cystitis. Many diagnoses were rejected or deemed unlikely, suggesting a need for studies to improve diagnostic accuracy for UTI. PMID:24498394

Accurate information on the facility costs of treatment is essential to enhance decision making and funding for malaria control. The objective of this study was to estimate the costs of providing treatment for uncomplicated malaria through a public health facility in Nigeria. Hospital costs were estimated from a provider perspective, applying a standard costing procedure. Capital and recurrent expenditures were estimated using an ingredient approach combined with step-down methodology. Costs attributable to malaria treatment were calculated based on the proportion of malaria cases to total outpatient visits. The costs were calculated in local currency [Naira (N)] and converted to US dollars at the 2013 exchange rate. Total annual costs of N28.723 million (US$182,953.65) were spent by the facility on the treatment of uncomplicated malaria, at a rate of US$31.49 per case, representing approximately 25% of the hospital's total expenditure in the study year. Personnel accounted for over 82.5% of total expenditure, followed by antimalarial medicines at 6.6%. More than 45% of outpatients visits were for uncomplicated malaria. Changes in personnel costs, drug prices and malaria prevalence significantly impacted on the study results, indicating the need for improved efficiency in the use of hospital resources. Malaria treatment currently consumes a considerable amount of resources in the facility, driven mainly by personnel cost and a high proportion of malaria cases. There is scope for enhanced efficiency to prevent waste and reduce costs to the provider and ultimately the consumer.

Escherichia coli urine isolates from patients presenting to the emergency department at a German tertiary care hospital were retrospectively analyzed from January 2015-March 2017 to determine antibiotic resistance patterns and patient risk factors for resistance. Uncomplicated urinary tract infection (UTI) was defined as UTI in the otherwise healthy patient without relevant co-morbidities and complications. Patients were assumed to have UTI if diagnosis was made by the attending physician with conclusive dipstick results. For subgroup analysis, only patients with symptoms suggestive for UTI documented in their records were included. 228 patients with a UTI diagnosed by the attending physician with E. coli isolated in urine culture were included. 154/228 patients had documented symptomatic UTI, 57/154 had uncomplicated infection, 76/154 patients had cystitis, and 124/154 were female. Resistance rates of uncomplicated UTI in symptomatic patients were: ciprofloxacin 10.5%, cotrimoxazole 15.8%, amoxicillin/clavulanic acid 5.3%, nitrofurantoin 0% (CLSI MICs). Previous hospitalization in the last 3 months (including patients living in a long-term care facility) was significantly correlated with resistance to ciprofloxacin, cotrimoxazole and amoxicillin/clav. Previous hospitalization was a strong predictor of resistance to ciprofloxacin and cotrimoxazole in multivariate analysis also. Other risk factors correlated with resistance were hematological malignancy (for cotrimoxazole) and renal transplantation (for ciprofloxacin). Cotrimoxazole is still an alternative for treating uncomplicated cystitis. Previous hospitalization in the last 3 months was a strong predictor of resistance to cotrimoxazole and ciprofloxacin. Other risk factors which might help guide empirical therapy are hematological malignancy and renal transplantation.

To evaluate sonographic findings as indicators of complicated versus uncomplicated appendicitis in the setting of known appendicitis, a necessary distinction in deciding whether to proceed with antibiotic therapy or with appendectomy. With Institutional Review Board approval and Health Insurance Portability and Accountability Act compliance, appendiceal sonograms of 119 patients with histopathologically proven appendicitis were retrospectively blindly reviewed to determine the presence or absence of the normally echogenic submucosal layer, the presence of mural hyperemia, periappendiceal fluid, appendicoliths, and hyperechoic periappendiceal fat and to determine the maximum outside diameter. Results were compared with the presence of complicated versus uncomplicated appendicitis on histopathologic examination and assessed by both univariate and mulitvariate logistic regression; confidence intervals (CIs) of proportions were assessed by the exact binomial test. Thirty-two (26.9%) of the 119 patients had complicated appendicitis, including 11 with gangrenous appendicitis without perforation and 21 with gangrenous appendicitis and perforation. Loss of the submucosal layer was the only independent significant indicator of complicated appendicitis in multivariate regression (P < .001) and provided sensitivity and specificity values of 100.0% (95% CI, 89.1%-100.0%) and 92.0% (95% CI, 84.1%-96.7%), respectively. Loss of the normally echogenic submucosal layer was the most useful sonographic finding for discriminating complicated from uncomplicated appendicitis, being the only finding independently and significantly associated with complicated appendicitis and, additionally, providing both high sensitivity and high specificity. This information may help a physician decide whether to proceed with antibiotic therapy or with appendectomy when treating a patient with appendicitis. © 2016 by the American Institute of Ultrasound in Medicine.

Estimate the causes and risk of death, specifically seizure related, in children followed from onset of epilepsy and to contrast the risk of seizure-related death with other common causes of death in the population. Mortality experiences from 4 pediatric cohorts of newly diagnosed patients were combined. Causes of death were classified as seizure related (including sudden unexpected death [SUDEP]), natural causes, nonnatural causes, and unknown. Of 2239 subjects followed up for >30 000 person-years, 79 died. Ten subjects with lethal neurometabolic conditions were ultimately excluded. The overall death rate (per 100 000 person-years) was 228; 743 in complicated epilepsy (with associated neurodisability or underlying brain condition) and 36 in uncomplicated epilepsy. Thirteen deaths were seizure-related (10 SUDEP, 3 other), accounting for 19% of all deaths. Seizure-related death rates were 43 overall, 122 for complicated epilepsy, and 14 for uncomplicated epilepsy. Death rates from other natural causes were 159, 561, and 9, respectively. Of 48 deaths from other natural causes, 37 were due to pneumonia or other respiratory complications. Most excess death in young people with epilepsy is not seizure-related. Mortality is significantly higher compared with the general population in children with complicated epilepsy but not uncomplicated epilepsy. The SUDEP rate was similar to or higher than sudden infant death syndrome rates. In uncomplicated epilepsy, sudden and seizure-related death rates were similar to or higher than rates for other common causes of death in young people (eg, accidents, suicides, homicides). Relating the risk of death in epilepsy to familiar risks may facilitate discussions of seizure-related mortality with patients and families.

Component processes of memory in alcoholism: pattern of compromise and neural substrates.

Initially, alcohol-related memory deficits were considered only through the prism of Korsakoff's syndrome (KS). It is now clear, however, that chronic alcohol consumption results in memory disorders in alcoholics without ostensible neurologic complications, such as Wernicke's encephalopathy and KS. Most of the principal memory components are affected, including working memory, episodic memory, semantic memory, perceptual memory, and procedural memory. The extent of those cognitive impairments depends on several factors, such as age, gender, nutritional status, and psychiatric comorbidity. While memory disorders, especially episodic memory deficits, are largely definitive in patients with KS, recovery of memory abilities has been described with abstinence in uncomplicated alcoholics. Neuropsychologic impairments, and especially memory disorders, must be evaluated at alcohol treatment entry because they could impede patients from benefiting fully from cognitive and behavioral treatment approaches for alcohol dependence. Screening of memory deficits could also enable clinicians to detect, among alcoholics without ostensible neurologic complications, those at risk of developing permanent and debilitating amnesia that features KS. © 2014 Elsevier B.V.

Viruses of the tick-borne encephalitis (TBE) antigenic complex, within the family Flaviviridae, cause a variety of diseases including uncomplicated febrile illness, encephalitis, meningo-encephalitis, hemorrhagic fever and chronic disease in humans, domesticated animals or wildlife species. TBE is a serious problem in Latvia with up to a 1,000 patients confirmed serologically annually 1994-1995. No previous data had been reported on the causative agent of TBE in Latvia. In the present study, a virus was isolated from serum of a patient with clinical symptoms of an acute TBE infection. Nucleotide sequence information obtained by direct reverse transcription-polymerase chain reaction (RT-PCR) and the serological characteristics of the isolated virus strain, designated TBE-Latvia-1-96, indicated a closer relationship to the Vasilchenko strain, isolated in Novosibirsk (Siberia, Russia), as compared to the western European or far eastern subtypes of TBE viruses. In a mouse neurovirulence assay, a significant difference in survival rates (days) was shown between Latvia-1-96 and the western European TBE virus subtype. Copyright 2000 Wiley-Liss, Inc.

To discuss the diagnostic and therapeutic challenges presented by an adolescent girl with delayed postural headaches and photophobia that occurred three months after an apparently uncomplicated microscopic lumbar discectomy. A previously healthy girl was admitted to our hospital with a one-week history of an unremitting, frontal-retroorbital postural headache and photophobia. Three months before admission, the patient had undergone a L5-S1 left hemilaminotomy and foraminotomy with microdiscectomy for excision of a herniated intervertebral disc. Conservative treatment failed to provide symptomatic relief. Cranial magnetic resonance imaging showed enhancement of the pachymeninges, consistent with intracranial hypotension. A chronic cerebrospinal leak was identified by high-resolution computed tomography (CT) myelography. Epidural blood patches were performed, with and without CT guidance, that provided temporary relief of the patient's symptoms; however, direct suture plication of the dural tear was eventually required for definitive treatment. This case emphasizes that delayed presentation of dural injury may occur after lumbar surgery and describes the potential therapeutic implications for this unusual complication.

Uveitis-Glaucoma-Hyphaema Syndrome. General review.

PubMed

Zemba, Mihail; Camburu, Georgiana

2017-01-01

Uveitis-Glaucoma-Hyphaema Syndrome (UGH syndrome, or "Ellingson" Syndrome) is a rare condition caused by the mechanical trauma of an intraocular lens malpositioned over adjacent structures (iris, ciliary body, iridocorneal angle), leading to a spectrum of iris transillumination defects, microhyphaemas and pigmentary dispersion, concomitant with elevated intraocular pressure (IOP). UGH Syndrome can also be characterized by chronic inflammation, secondary iris neovascularization, cystoid macular edema (CME). The fundamental step in the pathogenesis of UGH syndrome appears to arise from repetitive mechanical iris trauma by a malpositioned or subluxed IOL. These patients have uncomplicated cataract implants and return for episodes of blurry vision weeks to months after surgery. This may be accompanied by pain, photophobia, erythropsia, anterior uveitis, hyphaema along with raised intraocular pressure. A careful history and examination, as well as appropriate investigations can confirm the diagnostic. Treatment options are IOL Explantation exchange, topical and systemic medication, and cyclophotocoagulation, the placement of a Capsular Tension Ring to redistribute zonular tension and Anti-vascular endothelial growth factor (anti-VEGF) Therapy.

Uncomplicated urinary tract infections (UTI) are common in primary care. Whilst primary care physicians are called to be antimicrobial stewards, there is limited primary care antibiotic resistance surveillance and physician antibiotic prescription data available in southern Chinese primary care. The study aimed to investigate the antibiotic resistance rate and antibiotic prescription patterns in female patients with uncomplicated UTI. Factors associated with antibiotic resistance and prescription was explored. A prospective cohort study was conducted in 12 primary care group clinics in Hong Kong of patients presenting with symptoms of uncomplicated UTI from January 2012 to December 2013. Patients’ characteristics such as age, comorbidity, presenting symptoms and prior antibiotic use were recorded by physicians, as well as any empirical antibiotic prescription given at presentation. Urine samples were collected to test for antibiotic resistance of uropathogens. Univariate analysis was conducted to identify factors associated with antibiotic resistance and prescription. A total of 298 patients were included in the study. E. coli was detected in 107 (76%) out of the 141 positive urine samples. Antibiotic resistance rates of E. coli isolates for ampicillin, co-trimoxazole, ciprofloxacin, amoxicillin and nitrofurantoin were 59.8%, 31.8%, 23.4%, 1.9% and 0.9% respectively. E. coli isolates were sensitive to nitrofurantoin (98.1%) followed by amoxicillin (78.5%). The overall physician antibiotic prescription rate was 82.2%. Amoxicillin (39.6%) and nitrofurantoin (28.6%) were the most common prescribed antibiotics. Meanwhile, whilst physicians in public primary care prescribed more amoxicillin (OR: 2.84, 95% CI: 1.67 to 4.85, P<0.001) and nitrofurantoin (OR: 2.01, 95% CI: 1.14 to 3.55, P = 0.015), physicians in private clinics prescribed more cefuroxime and ciprofloxacin (P<0.05). Matching of antibiotic prescription and antibiotic sensitivity of E. coli isolates occurred in public than private primary care prescriptions (OR: 6.72, 95% CI: 2.07 to 21.80 P = 0.001) and for other uropathogens (OR: 6.19, 95% CI: 1.04 to 36.78 P = 0.034). Mismatching differences of antibiotic prescription and resistance were not evident. In conclusion, nitrofurantoin and amoxicillin should be used as first line antibiotic treatment for uncomplicated UTI. There were significant differences in antibiotic prescription patterns between public and private primary care. Public primary care practitioners were more likely to prescribe first line antibiotic treatment which match antibiotic sensitivity of E. coli isolates and other uropathogens. Further exploration of physician prescribing behaviour and educational interventions, particularly in private primary care may helpful. Meanwhile, development and dissemination of guidelines for primary care management of uncomplicated UTI as well as continued surveillance of antibiotic resistance and physician antibiotic prescription is recommended.

This study aimed to compare the self-esteem of Brazilian adolescents with epilepsy and Brazilian adolescents without this condition and the correlations between self-esteem of these adolescents with depression and anxiety symptoms. Study participants were 101 adolescents of both sexes, aged 10-19years old, from elementary and high school education. Fifty patients diagnosed with uncomplicated epilepsy attending the pediatric epilepsy clinic of University Hospital composed the case group. The other fifty-one adolescents without this diagnosis were attending public schools in Campinas-SP region. The instruments used were: identification card with demographics and epilepsy data, Multidimensional Self-Esteem Scale, Beck Depression Inventory and Inventory of State-Trait Anxiety - IDATE. A statistically significant result was found in the Responsibility Self-esteem Dimension favoring the control group. Significant correlations between self-esteem scores and anxiety and depression symptoms were also found. The development of a chronic disease such as epilepsy leads to a change in the way the individual perceives himself and the social environment he is inserted, influencing his behavior. The way people with epilepsy experience their seizures is a subjective measure that will control his/her well-being. Childhood and adolescence form the basis for a healthy emotional development; thus, our results show the importance of studying how subjective variables relate to the physical aspects of a chronic disease in these life stages.

The present study shows that 2-3 weeks after medical treatment the status of middle ear mucosa in draining ears is similar to that of dry ears for at least 3 months. To measure the time required for an inflamed middle ear mucosa to return into optimal state after appropriate medical treatment in chronic suppurative otitis media (CSOM). To assess optimal timing for elective surgical treatment of draining ears in uncomplicated CSOM. In this prospective study, the Eustachian tube (ET) mucociliary clearance time (MCT) was used as the method to demonstrate the status of middle ear mucosa. In group 1 (28 patients) ET-MCT was measured in ears that were free of drainage for at least 3 months. In Group 2 (21 patients), ET-MCT was measured in draining ears, who responded to 10-14 days medical treatment, at presentation, after 10 days and 1 month. The ET-MCT was 8.63 ± 1.32 min in group 1 and 28.96 ± 8.19 min in group 2 at presentation; and the difference was statistically significant (p < 0.001). The ET-MCT was 14.76 ± 5.11 min after 10 days and 9.31 ± 2.33 min after 1 month in group 2. The ET-MCT was indifferent between groups 1 and 2 after 1 month (p = 0.235).

Most natural orifice transluminal endoscopic surgery (NOTES) procedures to date rely on the hybrid technique with simultaneous laparoscopic access to protect against access-related complications and to achieve adequate triangulation for dissection. This is done at the cost of the potential benefits of this new minimally invasive technique. This study aimed to evaluate the feasibility and safety of a transgastric (TG) pure-NOTES procedure in a diagnostic setting. A TG pure-NOTES procedure with endoscopic ultrasonograpy (EUS)-guided access and over-the-scope-clip (OTSC) closure was performed for 10 pigs in a survival and feasibility study. A full macroscopic necropsy with subsequent histologic evaluation was performed on postoperative day (POD) 14. The outcome parameters were uncomplicated follow-up assessment, survival, intraoperative complications, intraabdominal pathology, macroscopic full-thickness closure, and histology-proven full-thickness healing of the gastrotomy. An uncomplicated postoperative course was reported for 9 of the 10 pigs, and survival was reported for all 10 pigs. For all the pigs, EUS-guided access was performed successfully with a median duration of 25 min (range, 12-62 min) and without intraoperative complications or access-related lesions at necropsy. An OTSC closure was achieved with a median duration of 11 min (range, 3-28 min). The OTSC provided immediate closure, but according to the authors' definition of a full-thickness healing evaluated by histologic examination, this was not achieved in any of the cases. Although all the animals survived until POD 14, intraabdominal chronic abscesses were present in 3 of the 10 pigs at necropsy. The EUS-guided TG access proved to be feasible without access-related complications. Although OTSC provided an immediate closure, the histopathology raised concerns regarding the risk of perforation. Together with the high risk of intraabdominal infection, TG pure-NOTES is not yet ready for routine clinical practice.

Summary Background and objectives The objective of this study was to determine the clinical significance of renal vascular lesions in lupus nephritis. Design, setting, participants, & measurements Renal vascular lesions defined as thrombotic microangiopathy, lupus vasculopathy, uncomplicated vascular immune deposits, and arterial sclerosis were evaluated in relation to renal and vascular morbidity and overall mortality. Results Biopsies from 161 patients revealed thrombotic microangiopathy (13), lupus vasculopathy (5), and arterial sclerosis (93). No renal vascular lesions were found in 24.8% of patients. At the time of biopsy, arterial sclerosis or lupus vasculopathy patients were older (arterial sclerosis=37.9±13.0 and lupus vasculopathy=44.4±8.9 versus controls=33.1±8.9 years, P<0.05), and the mean arterial pressure was higher in all groups compared with controls. Nephritis subtype, activity indices, and proteinuria were similar between groups, estimated GFR was lower in arterial sclerosis (70.5±33.3 versus 84.5±26.6 ml/min per 1.73 m2, P=0.03), and chronicity index (thrombotic microangiopathy=3.5, lupus vasculopathy=4.5, and arterial sclerosis=2.5) was higher in all renal vascular lesions subgroups versus controls (1.0, P<0.05). In 133 patients with similar follow-up, the association between renal vascular lesions and vascular events was significant (Fisher exact test, P=0.002) and remained so after multivariate analysis (exact conditional scores test, P=0.04), where the difference between arterial sclerosis and uncomplicated vascular immune deposits was most noticeable (odds ratio [95% confidence interval]=8.35[0.98, 83.12], P=0.05). The associations between renal vascular lesions, renal outcomes, and death were not significant, likely because of insufficient power. Conclusions Renal vascular lesions are common in SLE patients with nephritis and may be associated with arterial vascular events. PMID:22442181

To examine the between-hospital variation of charges and discounted prices for uncomplicated vaginal and caesarean section deliveries, and to determine the institutional and market-level characteristics that influence adjusted charges. Using data from the California Office of Statewide Health Planning and Development (OSHPD), we conducted a cross-sectional study of all privately insured patients admitted to California hospitals in 2011 for uncomplicated vaginal delivery (diagnosis-related group (DRG) 775) or uncomplicated caesarean section (DRG 766). Hospital charges and discounted prices adjusted for each patient's clinical and demographic characteristics. We analysed 76 766 vaginal deliveries and 32 660 caesarean sections in California in 2011. After adjusting for patient demographic and clinical characteristics, we found that the average California woman could be charged as little as US$3296 or as much as US$37 227 for a vaginal delivery, and US$8312-US$70 908 for a caesarean section depending on which hospital she was admitted to. The discounted prices were, on an average, 37% of the charges. We found that hospitals in markets with middling competition had significantly lower adjusted charges for vaginal deliveries, while hospitals with higher wage indices and casemixes, as well as for-profit hospitals, had higher adjusted charges. Hospitals in markets with higher uninsurance rates charged significantly less for caesarean sections, while for-profit hospitals and hospitals with higher wage indices charged more. However, the institutional and market-level factors included in our models explained only 35-36% of the between-hospital variation in charges. These results indicate that charges and discounted prices for two common, relatively homogeneous diagnosis groups-uncomplicated vaginal delivery and caesarean section-vary widely between hospitals and are not well explained by observable patient or hospital characteristics.

To describe the risk of maternal sepsis associated with obesity and other understudied risk factors such as operative vaginal delivery. Population-based, case-control study. North NHS region of Scotland. All cases of pregnant, intrapartum and postpartum women with International Classification of Disease-9 codes for sepsis or severe sepsis recorded in the Aberdeen Maternal and Neonatal Databank (AMND) from 1986 to 2009. Four controls per case selected from the AMND were frequency matched on year-of-delivery. Cases and controls were compared; significant variables from univariable regression were adjusted in a multivariable logistic regression model. Dependent variables were uncomplicated sepsis or severe ('near-miss') sepsis. Independent variables were demographic, medical and clinical delivery characteristics. Unadjusted and adjusted odds ratios (OR) with 95% confidence intervals (95% CI) are reported. Controlling for mode of delivery and demographic and clinical factors, obese women had twice the odds of uncomplicated sepsis (OR 2.12; 95% CI 1.14-3.89) compared with women of normal weight. Age <25 years (OR 5.15; 95% CI 2.43-10.90) and operative vaginal delivery (OR 2.20; 95% CI 1.02-4.87) were also significant predictors of sepsis. Known risk factors for maternal sepsis were also significant in this study (OR for uncomplicated and severe sepsis respectively): multiparity (OR 6.29, 12.04), anaemia (OR 3.43, 18.49), labour induction (OR 3.92 severe only), caesarean section (OR 3.23, 13.35), and preterm birth (OR 2.46 uncomplicated only). Obesity, operative vaginal delivery and age <25 years are significant risk factors for sepsis and should be considered in clinical obstetric care. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

Objective. To compare the clinical outcome of patients presenting with symptoms of uncomplicated cystitis who were seen by a doctor, with patients who were given treatment following a diagnostic algorithm. Design. Randomized controlled trial. Setting. Out-of-hours service, Oslo, Norway. Intervention. Women with typical symptoms of uncomplicated cystitis were included in the trial in the time period September 2010–November 2011. They were randomized into two groups. One group received standard treatment according to the diagnostic algorithm, the other group received treatment after a regular consultation by a doctor. Subjects. Women (n = 441) aged 16–55 years. Mean age in both groups 27 years. Main outcome measures. Number of days until symptomatic resolution. Results. No significant differences were found between the groups in the basic patient demographics, severity of symptoms, or percentage of urine samples with single culture growth. A median of three days until symptomatic resolution was found in both groups. By day four 79% in the algorithm group and 72% in the regular consultation group were free of symptoms (p = 0.09). The number of patients who contacted a doctor again in the follow-up period and received alternative antibiotic treatment was insignificantly higher (p = 0.08) after regular consultation than after treatment according to the diagnostic algorithm. There were no cases of severe pyelonephritis or hospital admissions during the follow-up period. Conclusion. Using a diagnostic algorithm is a safe and efficient method for treating women with symptoms of uncomplicated cystitis at an out-of-hours service. This simplification of treatment strategy can lead to a more rational use of consultation time and a stricter adherence to National Antibiotic Guidelines for a common disorder. PMID:25961367

Gonorrhea, the sexually transmitted disease (STD) caused by Neisseria gonorrhoeae, is the second most common notifiable disease in the United States after chlamydia; 468,514 cases were reported to state and local health departments in 2016, an increase of 18.5% from 2015 (1). N. gonorrhoeae has progressively developed resistance to most antimicrobials used to treat the infection (2). As a result, CDC recommends two antimicrobials (250 mg of ceftriaxone [IM] plus 1 g of azithromycin [PO]) for treating uncomplicated gonorrhea to improve treatment efficacy and, potentially, to slow the emergence and spread of antimicrobial resistance. To monitor adherence to the current CDC-recommended regimen for uncomplicated gonorrhea, CDC reviewed enhanced data collected on a random sample of reported cases of gonorrhea in seven jurisdictions participating in the STD Surveillance Network (SSuN) and estimated the proportion of patients who received the CDC-recommended regimen for uncomplicated gonorrhea, by patient characteristics and diagnosing facility type. In 2016, the majority of reported patients with gonorrhea (81%) received the recommended regimen. There were no differences in the proportion of patients receiving the recommended regimen by age or race/ethnicity; however, patients diagnosed with gonorrhea in STD (91%) or family planning/reproductive health (94%) clinics were more likely to receive this regimen than were patients diagnosed in other provider settings (80%). These data document high provider adherence to CDC gonorrhea treatment recommendations in specialty STD clinics, indicating high quality of care provided in those settings. Local and state health departments should monitor adherence with recommendations in their jurisdictions and consider implementing interventions to improve provider and patient compliance with gonorrhea treatment recommendations where indicated.

Emergence of artemisinin resistance has raised concerns that the most potent anti-malarial drug may be under threat. Artesunate-amodiaquine (AS-AQ) and artemether-lumefantrine (AL) are, respectively, the first- and second-line treatments for uncomplicated falciparum malaria in Côte d'Ivoire. Constant monitoring by National Malaria Control Programme (NMCP) of drug efficacy is an important tool in establishing rational anti-malarial drug policies in Côte d'Ivoire. In an open label, randomized controlled clinical trial, children and adults were randomized to receive AS-AQ or AL. Both drug regimens were given for three days, and follow-up was for 42 days. The primary endpoint was the 42-day cure rate and was defined as proportion of patients with PCR-corrected cure rate after 42 days of follow-up. A total of 383 patients who were attending the Anonkoua-koute (Abidjan), Petit Paris (Korhogo) and Libreville (Man) hospitals and presenting with symptomatic acute uncomplicated falciparum malaria were randomized to receive AS-AQ (188) and AL (195). The intention-to-treat analysis showed effectiveness rates of 94.7% and 96.4% for AS-AQ and AL, respectively on day 42. After adjustment for PCR, these rates were 96.8% and 99%, respectively. At day 42, in per-protocol analysis, Adequate clinical and parasitological response (ACPR) PCR uncorrected was 97.8% and 97.4% for AS-AQ and AL, respectively. The PCR adjusted ACPR was 100% for each combination and both regimens were well tolerated. This study has shown the high efficacy of AS-AQ in patients of all ages with acute uncomplicated falciparum malaria and AS-AQ was non-inferior to AL. Continuous efficacy monitoring is recommended.

Alcohol withdrawal syndrome (AWS) is a distressing condition, generally controlled by benzodiazepines (BZD's). Baclofen, a gamma-aminobutyric acid-B (GABAB) agonist, has also shown promising results in controlling AWS. As there are few studies comparing the efficacy and tolerability of chlordiazepoxide with baclofen, the present study was taken up. The objective of this study was to compare efficacy and tolerability of baclofen with chlordiazepoxide in uncomplicated AWS. Sixty subjects with uncomplicated AWS were randomized into two groups of 30 each, to receive baclofen (30 mg) or chlordiazepoxide (75 mg) in decremented fixed dose regime for 9 days. Clinical efficacy was assessed by Clinical Institute Withdrawal Assessment for Alcohol-Revised Scale (CIWA-Ar) and tolerability by the nature and severity of adverse events. Lorazepam was used as rescue medication. Secondary efficacy parameters were Clinical Global Impression scores, symptom-free days, and subject satisfaction as assessed by visual analog scale. This study was registered with Clinical Trial Registry-India (CTRI/2013/04/003588), also subsequently registered with WHO's ICTRP clinical trial portal. Both baclofen and chlordiazepoxide showed a consistent reduction in the total CIWA-Ar scores. However, chlordiazepoxide showed a faster and a more effective control of anxiety and agitation requiring lesser lorazepam supplementation, and also showed a better subject satisfaction compared to baclofen. Both the drugs showed good tolerability with mild self-limiting adverse events. The present study demonstrates that baclofen is not as good as chlordiazepoxide in the treatment of uncomplicated AWS. However, baclofen might be considered as an alternative. Copyright © 2016 Chang Gung University. Published by Elsevier B.V. All rights reserved.

Dihydroartemisinin-piperaquine (DHP) has been the first-line treatment of uncomplicated malaria due to both Plasmodium falciparum and Plasmodium vivax infections in Papua, Indonesia, since March 2006. The efficacy of DHP was reassessed to determine whether there had been any decline following almost a decade of its extensive use. An open-label drug efficacy study of DHP for uncomplicated P. falciparum and P. vivax malaria was carried out between March 2015 and April 2016 in Timika, Papua, Indonesia. Patients with uncomplicated malaria were administered supervised DHP tablets once daily for 3 days. Clinical and laboratory data were collected daily until parasite clearance and then weekly for 6 weeks. Molecular analysis was undertaken for all patients with recurrent parasitemia. A total of 129 study patients were enrolled in the study. At day 42, the polymerase chain reaction-adjusted efficacy was 97.7% (95% confidence intervals [CI]: 87.4-99.9) in the 61 patients with P. falciparum malaria, and 98.2% [95% CI: 90.3-100] in the 56 patients with P. vivax malaria. By day 2, 98% (56/57) of patients with P. falciparum and 96.9% (63/65) of those with P. vivax had cleared their peripheral parasitemia; none of the patients were still parasitaemic on day 3. Molecular analysis of P. falciparum parasites showed that none (0/61) had K13 mutations associated previously with artemisinin resistance or increased copy number of plasmepsin 2-3 (0/61). In the absence of artemisinin resistance, DHP has retained high efficacy for the treatment of uncomplicated malaria despite extensive drug pressure over a 9-year period.

Background To update the National Malaria Control Programme of Mali on the efficacy of chloroquine, amodiaquine and sulphadoxine-pyrimethamine in the treatment of uncomplicated falciparum malaria. Methods During the malaria transmission seasons of 2002 and 2003, 455 children – between six and 59 months of age, with uncomplicated malaria in Kolle, Mali, were randomly assigned to one of three treatment arms. In vivo outcomes were assessed using WHO standard protocols. Genotyping of msp1, msp2 and CA1 polymorphisms were used to distinguish reinfection from recrudescent parasites (molecular correction). Results Day 28 adequate clinical and parasitological responses (ACPR) were 14.1%, 62.3% and 88.9% in 2002 and 18.2%, 60% and 85.2% in 2003 for chloroquine, amodiaquine and sulphadoxine-pyrimethamine, respectively. After molecular correction, ACPRs (cACPR) were 63.2%, 88.5% and 98.0% in 2002 and 75.5%, 85.2% and 96.6% in 2003 for CQ, AQ and SP, respectively. Amodiaquine was the most effective on fever. Amodiaquine therapy selected molecular markers for chloroquine resistance, while in the sulphadoxine-pyrimethamine arm the level of dhfr triple mutant and dhfr/dhps quadruple mutant increased from 31.5% and 3.8% in 2002 to 42.9% and 8.9% in 2003, respectively. No infection with dhps 540E was found. Conclusion In this study, treatment with sulphadoxine-pyrimethamine emerged as the most efficacious on uncomplicated falciparum malaria followed by amodiaquine. The study demonstrated that sulphadoxine-pyrimethamine and amodiaquine were appropriate partner drugs that could be associated with artemisinin derivatives in an artemisinin-based combination therapy.

The most appropriate closure for the appendicular stump with either endoloops or an endostapler in laparoscopic appendectomy remains unclear and under debate because of limited and conflicting evidence. In a 2-month prospective, observational, resident-led nationwide cohort study, patients undergoing laparoscopic appendectomy for both uncomplicated and complicated appendicitis were analysed. Logistic regression analyses were performed for identifying the possible effect of stump closure type and other risk factors for infectious complications. Laparoscopic appendectomy for acute appendicitis was performed in 1369 patients in 62 hospitals; endoloops were used in 76.7 % and an endostapler in other patients. Median operating time was not different between endoloop and endostapler use (42.0 vs. 44.0 min, P = 0.243). A superficial surgical site infection was seen in 2.0 % after uncomplicated appendicitis and in 0.8 % after complicated appendicitis. The intra-abdominal abscess rate was 1.9 % after uncomplicated and 11.0 % after complicated appendicitis. No significant effect of stump closure type was observed for any infectious complication (OR 1.05; 95 % CI 0.625-1.766, P = 0.853) or an intra-abdominal abscess (OR OR 0.96; 95 % CI 0.523-1.768, P = 0.899). In multivariable analysis, complicated appendicitis was identified as the only independent risk factor for an intra-abdominal abscess (OR 6.26; 95 % CI 3.454-11.341, P < 0.001). The infectious complication rate is not influenced by the type of appendicular stump closure with either endoloops or an endostapler in this study. If technically feasible, closure with endoloops is advised for cost considerations.

To implement a program of early hospital discharge after an uncomplicated birth, in order to improve the effectiveness, as well as ensuring clinical safety and patient acceptability. Descriptive study of the effectiveness of an early discharge program after uncomplicated delivery between February 2012 and September 2013. The populations are post-partum women and newborns admitted to the University Hospital of Fuenlabrada, with a duration of less than 24h after uncomplicated delivery that met the defined inclusion criteria. Satisfaction was assessed using a Likert scale. The effectiveness of the program was monitored by safety indicators, productivity, adaptation, and continuity of care. A total of 20% of cases capable of early discharge from Fuenlabrada University Hospital completed the program. Almost all (94%) were normal deliveries. The 188 cases included were from 911 patients with uncomplicated childbirth, accounting for 6.5% of the 2,857 total births. The mean stay of patients included showed a decrease of 50% (2.4 to 1.2 days). All patients received continuity of care after hospital discharge. The review consultation was reprogrammed for 4.8% of cases, with 2% of patients re-admitted within 96h. with no serious problems. Four newborns (2%) required attention in the emergency department (mother or newborn) before 96h. The assessment of patient satisfaction achieved a score of 4.5 out of 5. The program achieved a decrease in the average stay by 50%, favouring the autonomy of midwives. This acceptance level is in line with similar interventions. The deployment of the program may be useful for other changes in care processes. Copyright © 2016 SECA. Publicado por Elsevier España, S.L.U. All rights reserved.

The aim of this study is to detect the presence of and possible relation between virulence genes and antibiotic resistance in E. coli strains isolated from patients with acute, uncomplicated urinary tract infections (UTI). 62 E. coli strains isolated from patients with acute, uncomplicated urinary tract infections (50 strains isolated from acute uncomplicated cystitis cases (AUC); 12 strains from acute uncomplicated pyelonephritis cases (AUP)) were screened for virulence genes [pap (pyelonephritis-associated pili), sfa/foc (S and F1C fimbriae), afa (afimbrial adhesins), hly (hemolysin), cnf1 (cytotoxic necrotizing factor), aer (aerobactin), PAI (pathogenicity island marker), iroN (catecholate siderophore receptor), ompT (outer membrane protein T), usp (uropathogenic specific protein)] by PCR and for antimicrobial resistance by disk diffusion method according to CLSI criteria. It was found that 56 strains (90.3%) carried at least one virulence gene. The most common virulence genes were ompT (79%), aer (51.6%), PAI (51.6%) and usp (56.5%). 60% of the strains were resistant to at least one antibiotic. The highest resistance rates were against ampicillin (79%) and co-trimoxazole (41.9%). Fifty percent of the E. coli strains (31 strains) were found to be multiple resistant. Eight (12.9%) out of 62 strains were found to be ESBL positive. Statistically significant relationships were found between the absence of usp and AMP - SXT resistance, iroN and OFX - CIP resistance, PAI and SXT resistance, cnf1 and AMP resistance, and a significant relationship was also found between the presence of the afa and OFX resistance. No difference between E. coli strains isolated from two different clinical presentations was found in terms of virulence genes and antibiotic susceptibility.

Inflammation has been shown to be related with acute aortic dissection (AAD). The present study aimed to evaluate the association of white blood cell counts (WBCc) on admission with both in-hospital and long-term all-cause mortality in patients with uncomplicated Stanford type B AAD. From 2008 to 2010, a total of 377 consecutive patients with uncomplicated type B AAD were enrolled and then followed up. Clinical data and WBCc on admission were collected. The primary end points were in-hospital death and long-term all-cause death. The in-hospital death rate was 4.2%, and the long-term all-cause mortality rate was 6.9% during a median follow-up of 18.9 months. WBCc on admission was identified as a risk factor for in-hospital death by univariate Cox regression analysis as both a continuous variable and a categorical variable using a cut off of 11.0 × 10 9 cell/L (all P < 0.05). After adjusting for age, sex and other risk factors, elevated admission WBCc was still a significant predictor for in-hospital death as both a continuous variable [hazard ratio (HR): 1.052, 95% CI: 1.024-1.336, P = 0.002] and a categorical variable using a cut off of 11.0 × 10 9 cell/L (HR: 2.056, 95% CI: 1.673-5.253, P = 0.034). No relationship was observed between WBCc on admission and long-term all-cause death. Our results indicate that elevated WBCc upon admission might be used as a predictor for increased risk of in-hospital death in uncomplicated type B AAD. There might be no predictive value of WBCc for the long-term survival of type B AAD.

Medical treatment of initially uncomplicated acute Stanford type-B aortic dissection is associated with a high rate of late adverse events. Identification of individuals who potentially benefit from preventive endografting is highly desirable. The association of computed tomography imaging features with late adverse events was retrospectively assessed in 83 patients with acute uncomplicated Stanford type-B aortic dissection, followed over a median of 850 (interquartile range 247-1824) days. Adverse events were defined as fatal or nonfatal aortic rupture, rapid aortic growth (>10 mm/y), aneurysm formation (≥6 cm), organ or limb ischemia, or new uncontrollable hypertension or pain. Five significant predictors were identified using multivariable Cox regression analysis: connective tissue disease (hazard ratio [HR] 2.94, 95% confidence interval [CI]: 1.29-6.72; P =0.01), circumferential extent of false lumen in angular degrees (HR 1.03 per degree, 95% CI: 1.01-1.04, P =0.003), maximum aortic diameter (HR 1.10 per mm, 95% CI: 1.02-1.18, P =0.015), false lumen outflow (HR 0.999 per mL/min, 95% CI: 0.998-1.000; P =0.055), and number of intercostal arteries (HR 0.89 per n, 95% CI: 0.80-0.98; P =0.024). A prediction model was constructed to calculate patient specific risk at 1, 2, and 5 years and to stratify patients into high-, intermediate-, and low-risk groups. The model was internally validated by bootstrapping and showed good discriminatory ability with an optimism-corrected C statistic of 70.1%. Computed tomography imaging-based morphological features combined into a prediction model may be able to identify patients at high risk for late adverse events after an initially uncomplicated type-B aortic dissection. © 2017 American Heart Association, Inc.

We aimed to update the 2010 evidence- and consensus-based national clinical guideline on the diagnosis and management of uncomplicated urinary tract infections (UTIs) in adult patients. Results are published in 2 parts. Part 1 covers methods, the definition of patient groups, and diagnostics. This second publication focuses on treatment of acute episodes of cystitis and pyelonephritis as well as on prophylaxis of recurrent UTIs. An interdisciplinary group consisting of 17 representatives of 12 medical societies and a patient representative was formed. Systematic literature searches were conducted in MEDLINE, EMBASE, and the Cochrane Library to identify literature published in 2010-2015. For the treatment of acute uncomplicated cystitis (AUC), fosfomycin-trometamol, nitrofurantoin, nitroxoline, pivmecillinam, and trimethoprim (depending on the local rate of resistance) are all equally recommended. Cotrimoxazole, fluoroquinolones, and cephalosporins are not recommended as antibiotics of first choice, for concern of an unfavorable impact on the microbiome. Mild to moderate uncomplicated pyelonephritis should be treated with oral cefpodoxime, ceftibuten, ciprofloxacin, or levofloxacin. For AUC with mild to moderate symptoms, instead of antibiotics symptomatic treatment alone may be considered depending on patient preference after discussing adverse events and outcomes. Primarily non-antibiotic options are recommended for prophylaxis of recurrent urinary tract infection. In accordance with the global antibiotic stewardship initiative and considering new insights in scientific research, we updated our German clinical UTI guideline to promote a responsible antibiotic use and to give clear hands-on recommendations for the diagnosis and management of UTIs in adults in Germany for healthcare providers and patients. © 2018 S.

With high-quality community-based primary care, hospitalizations for ambulatory care sensitive conditions (ACSC) are considered avoidable. The purpose of this study was to test the inter-physician reliability of judgments of avoidable hospitalizations for one ACSC, uncomplicated hypertension, derived from medical chart review. We applied the Canadian Institute for Health Information's case definition to obtain a random sample of patients who had an ACSC hospitalization for uncomplicated hypertension in Calgary, Alberta. Medical chart review was conducted by three experienced internal medicine specialists. Implicit methods were used to judge avoidability of hospitalization using a validated 5-point scale. There was poor agreement among three physicians raters when judging the avoidability of 82 ACSC hospitalizations for uncomplicated hypertension (κ = 0.092). The κ also remained low when assessing agreement between raters 1 and 3 (κ = 0.092), but the κ was lower (less than chance agreement) for raters 1 and 2 (κ = -0.119) and raters 2 and 3 (κ = -0.008). When the 5-point scale was dichotomized, there was fair agreement among three raters (κ = 0.217). The proportion of ACSC hospitalizations for uncomplicated hypertension that were rated as avoidable was 32.9%, 6.1% and 26.8% for raters 1, 2, and 3, respectively. This study found a low proportion of ACSC hospitalization were rated as avoidable, with poor to fair agreement of judgment between physician raters. This suggests that the validity and utility of this health indicator is questionable. It points to a need to abandon the use of ACSC entirely; or alternatively to work on the development of explicit criteria for judging avoidability of hospitalization for ACSC such as hypertension.

The treatment of uncomplicated severe acute malnutrition (SAM) requires substantial amounts of ready-to-use therapeutic food (RUTF). In 2009, Action Contre la Faim anticipated a shortfall of RUTF for their nutrition programme in Myanmar. A low-dose RUTF protocol to treat children with uncomplicated SAM was adopted. In this protocol, RUTF was dosed according to beneficiary's body weight, until the child reached a Weight-for-Height z-score of ≥−3 and mid-upper arm circumference ≥110 mm. From this point, the child received a fixed quantity of RUTF per day, independent of body weight until discharge. Specific measures were implemented as part of this low-dose RUTF protocol in order to improve service quality and beneficiary support. We analysed individual records of 3083 children treated from July 2009 to January 2010. Up to 90.2% of children recovered, 2.0% defaulted and 0.9% were classified as non-responders. No deaths were recorded. Among children who recovered, median [IQR] length of stay and weight gain were 42 days [28; 56] and 4.0 g kg–1 day–1 [3.0; 5.7], respectively. Multivariable logistic regression showed that children older than 48 months had higher odds of non-response to treatment than younger children (adjusted odds ratio: 3.51, 95% CI: 1.67–7.42). Our results indicate that a low-dose RUTF protocol, combined with specific measures to ensure good service quality and beneficiary support, was successful in treating uncomplicated SAM in this setting. This programmatic experience should be validated by randomised studies aiming to test, quantify and attribute the effect of the protocol adaptation and programme improvements presented here.

Complex Chiari malformation is a subgroup of Chiari 1 malformation with distinct imaging features. Children with complex Chiari malformation are reported to have a more severe clinical phenotype and sometimes require more extensive surgical treatment than those with uncomplicated Chiari 1 malformation. We describe reported MR imaging features of complex Chiari malformation and evaluate the utility of craniometric parameters and qualitative anatomical observations for distinguishing complex Chiari malformation from uncomplicated Chiari 1 malformation. We conducted a retrospective search of the institutional imaging database using the keywords "Chiari" and "Chiari 1" to identify children imaged during the 2006-2011 time period. Children with Chiari 2 malformation were excluded after imaging review. We used the first available diagnostic brain or cervical spine MR study for data measurement. Standard measurements and observations were made of obex level (mm), cerebellar tonsillar descent (mm), perpendicular distance to basion-C2 line (pB-C2, mm), craniocervical angle (degrees), clivus length, and presence or absence of syringohydromyelia, basilar invagination and congenital craniovertebral junction osseous anomalies. After imaging review, we accessed the institutional health care clinical database to determine whether each subject clinically met criteria for Chiari 1 malformation or complex Chiari malformation. Obex level and craniocervical angle measurements showed statistically significant differences between the populations with complex Chiari malformation and uncomplicated Chiari 1 malformation. Cerebellar tonsillar descent and perpendicular distance to basion-C2 line measurements trended toward but did not meet statistical significance. Odontoid retroflexion, craniovertebral junction osseous anomalies, and syringohydromyelia were all observed proportionally more often in children with complex Chiari malformation than in those with Chiari 1 malformation. Characteristic imaging features of complex Chiari malformation, especially obex level, permit its distinction from the more common uncomplicated Chiari 1 malformation.

Background Uncomplicated skin and soft tissue infections are among the most frequent indications for outpatient antibiotics. A detailed understanding of current prescribing practices is necessary to optimize antibiotic use for these conditions. Methods This was a retrospective cohort study of children and adults treated in the ambulatory care setting for uncomplicated cellulitis, wound infection, or cutaneous abscess between March 1, 2010 and February 28, 2011. We assessed the frequency of avoidable antibiotic exposure, defined as: use of antibiotics with broad gram-negative activity, combination antibiotic therapy, or treatment for 10 or more days. Total antibiotic-days prescribed for the cohort were compared to antibiotic-days in four hypothetical short-course (5 – 7 days), single-antibiotic treatment models consistent with national guidelines. Results 364 cases were included for analysis (155 cellulitis, 41 wound infection, and 168 abscess). Antibiotics active against methicillin-resistant Staphylococcus aureus were prescribed in 61% of cases of cellulitis. Of 139 cases of abscess where drainage was performed, antibiotics were prescribed in 80% for a median of 10 (interquartile range 7 – 10) days. Of 292 total cases where complete prescribing data were available, avoidable antibiotic exposure occurred in 46%. This included use of antibiotics with broad gram-negative activity in 4%, combination therapy in 12%, and treatment for 10 or more days in 42%. Use of the short-course, single-antibiotic treatment strategies would have reduced prescribed antibiotic-days by 19 – 55%. Conclusions Nearly half of uncomplicated skin infections involved avoidable antibiotic exposure. Antibiotic use could be reduced through treatment approaches utilizing short courses of a single antibiotic. PMID:24262724

Background Uncomplicated urinary tract infections (UTI) in dogs usually are treated with antimicrobial drugs for 10–14 days. Shorter duration antimicrobial regimens have been evaluated in human patients. Hypothesis A high dose short duration (HDSD) enrofloxacin protocol administered to dogs with uncomplicated UTI will not be inferior to a 14-day treatment regimen with amoxicillin-clavulanic acid. Animals Client-owned adult, otherwise healthy dogs with aerobic bacterial urine culture yielding ≥103 CFU/mL of bacteria after cystocentesis. Methods Prospective, multicenter, controlled, randomized blinded clinical trial. Enrolled dogs were randomized to group 1 (enrofloxacin 18–20 mg/kg PO q24h for 3 days) or group 2 (amoxicillin-clavulanic acid 13.75–25 mg/kg PO q12h for 14 days). Urine cultures were obtained at days 0, 10, and 21. Microbiologic and clinical cure rates were evaluated 7 days after antimicrobial treatment was discontinued. Lower urinary tract signs and adverse events also were recorded. Results There were 35 dogs in group 1 and 33 in group 2. The microbiologic cure rate was 77.1 and 81.2% for groups 1 and 2, respectively. The clinical cure rate was 88.6 and 87.9% for groups 1 and 2, respectively. Cure rates between groups did not differ according to the selected margin of noninferiority. Conclusions and Clinical Importance HDSD enrofloxacin treatment was not inferior to a conventional amoxicillin-clavulanic acid protocol for the treatment of uncomplicated bacterial UTI in dogs. Further research is warranted to determine if this protocol will positively impact owner compliance and decrease the emergence of antimicrobial resistance. PMID:22486931

Introduction The terminal ileum is the most involved tract in Crohn’s disease. The obstruction in this location is the most frequent complication. Acute or chronic presentations can occur. Surgery finds a role in the management of chronic strictures and in acute clinical presentations with complications not improving with conservative therapy. Patients and methods We investigate the outcome of patients with obstruction of the ileo-cecal bowel tract laparoscopically managed. It was analyzed the average operative time (OT), the conversion rate and the occurrence of re-operation due to surgical complications. Results 21 patients underwent an ileocecal resection for complicated Crohn’s disease between January 2013 and December 2014. The admissions were performed in emergency in 42% of patients. The pre-intervention hospital stay was 5.8 (Sd 6.23). The mean operative time was 154 min (Sd 41). 28% of the procedures were converted to open surgery. The average hospital stay was 10 days (Sd 5) in uncomplicated patients. The morbidity rate was 28%. In 19% of cases a re-intervention was needed due to anastomotic leakage (3pts) and one hemoperitoneum for bleeding from the suture line. Discussion Laparoscopy seems an affordable technique in the management of obstructive pattern of Crohn’s disease. It should be the preferable approach in young patients that probably will be submitted to subsequent surgery for the same disease; in fact, the reduced adhesions formation provided by the less bowel manipulation make easy the subsequent access. Older patients had usually more post-operative morbidity and mortality mostly due to pre-existing conditions; if possible in these patients the treatment should be medical. PMID:28098059

Objective To characterize a model of atypical antipsychotic drug-induced obesity and evaluate its mechanism. Research Methods and Procedures Chronically, olanzapine or clozapine was self-administered via cookie dough to rodents (Sprague-Dawley or Wistar rats; C57Bl/6J or A/J mice). Chronic studies measured food intake, body weight, adiponectin, active ghrelin, leptin, insulin, tissue wet weights, glucose, clinical chemistry endpoints, and brain dopaminergic D2 receptor density. Acute studies examined food intake, ghrelin, leptin, and glucose tolerance. Results Olanzapine (1 to 8 mg/kg), but not clozapine, increased body weight in female rats only. Weight changes were detectable within 2 to 3 days and were associated with hyperphagia starting ~24 hours after the first dose. Chronic administration (12 to 29 days) led to adiposity, hyperleptinemia, and mild insulin resistance; no lipid abnormalities or changes in D2 receptor density were observed. Topiramate, which has reversed weight gain from atypical anti-psychotics in humans, attenuated weight gain in rats. Acutely, olanzapine, but not clozapine, lowered plasma glucose and leptin. Increases in glucose, insulin, and leptin following a glucose challenge were also blunted. Discussion A model of olanzapine-induced obesity was characterized which shares characteristics of patients with atypical antipsychotic drug-induced obesity; these characteristics include hyperphagia, hyperleptinemia, insulin resistance, and weight gain attenuation by topiramate. This model may be a useful and inexpensive model of uncomplicated obesity amenable to rapid screening of weight loss drugs. Olanzapine-induced weight gain may be secondary to hyperphagia associated with acute lowering of plasma glucose and leptin, as well as the inability to increase plasma glucose and leptin following a glucose challenge.

We present a patient with lymphangioleiomyomatosis (LAM) on long-term sirolimus (now 79 months) who has had a second successful pregnancy. The second pregnancy on uninterrupted low-dose sirolimus (plasma levels 3-5 mg/L) was uncomplicated both with respect to mother and child suggesting that low-dose sirolimus might be safe in selected pregnant patients with stable LAM. The long-term time course in this patient is in agreement with recent reports of a long-term beneficial effect of sirolimus in LAM. In this patient, the pregnancies did not seem to impair the long-term improvement of lung-function on sirolimus.

Coronal fractures of the anterior teeth are common sequelae of traumatic dental injuries. Reattachment of fractured tooth fragments using dental adhesive techniques offers some advantages, including restoration of the function, esthetics, shape, texture, and brightness of the surface. The present report describes a clinical case of reattachment with a 4-year clinical and radiographic follow up in a permanent maxillary central incisor with an uncomplicated crown fracture. Fragment reattachment is a conservative procedure, preserving esthetics and functionality, and it can provide an immediate positive emotional response from the patient. © 2017 John Wiley & Sons A/S.

Acute uncomplicated cystitis (AUC) and acute uncomplicated pyelonephritis (AUP) are two common urinary tract infections (UTI) in otherwise healthy young women. Both weaknesses of the mucosal barrier and specific factors of uropathogenic bacteria must be present before the bacteria can adhere to the urothelium and give rise to an infection. These circumstances are also of relevance in recurrent UTI. Antibiotic treatment of AUC and AUP is based on the guidelines of the Infectious Diseases Society of America (IDSA). For the prevention of recurrent UTI, antibiotics, functional foods, injections, probiotic agents and other measures are recommended with varying potential for success.

A day centre was established to determine whether an alternative approach to the management of uncomplicated sickle pain would improve the quality of care and reduce hospital admissions in patients with sickle cell disease. Since the centre opened there has been a 43% decrease in hospital admissions and 49% decrease in occupied bed days. In the third year, 84% of patients treated for severe sickle pain were managed without the need for hospital admission. A centre offering day case management of painful crisis reduced unnecessary hospital admissions for uncomplicated pain. This approach is safe and cost-effective.

Treating uncomplicated malaria in children: comparing artemisinin-based combination therapies.

Yeka, Adoke; Harris, Jamal C

In response to increased resistance to conventional drugs, the WHO is promoting artemisinin-based combination therapy (ACT) for treating uncomplicated malaria. The objective of this report is to review the available evidence on the efficacy and effectiveness, acceptability, and deployment of ACT in resource-limited settings with a focus on sub-Saharan Africa. ACTs are very effective in the treatment of uncomplicated Plasmodium falciparum malaria in children. ACTs are relatively safe and tolerable with no reported resistance in sub-Saharan Africa despite indications of delayed clearance of infections in south-east Asia. The major challenges to the widespread use of ACT include its high cost, availability, and inefficient delivery due to, among other things, weak healthcare systems. ACTs are an essential tool in the fight to control and eliminate malaria. They are currently the most effective drugs against P. falciparum malaria. They should be deployed through programs that address availability, cost, adherence, and quality assurance. Initiatives including home-based management of malaria, improving public sector procurement and supply chains, and reducing private sector pricing should make ACTs more accessible for sub-Saharan African children who bear the brunt of the burden of malarial disease.

The safety of artemether-lumefantrine in patients with acute, uncomplicated Plasmodium falciparum malaria was investigated prospectively using the auditory brainstem response (ABR) and pure-tone thresholds. Secondary outcomes included polymerase chain reaction-corrected cure rates. Patients were randomly assigned in a 3:1:1 ratio to either artemether-lumefantrine (N = 159), atovaquone-proguanil (N = 53), or artesunate-mefloquine (N = 53). The null hypothesis (primary outcome), claiming that the percentage of patients with a baseline to Day-7 ABR Wave III latency increase of > 0.30 msec is ≥ 15% after administration of artemether-lumefantrine, was rejected; 2.6% of patients (95% confidence interval: 0.7–6.6) exceeded 0.30 msec, i.e., significantly below 15% (P < 0.0001). A model-based analysis found no apparent relationship between drug exposure and ABR change. In all three groups, average improvements (2–4 dB) in pure-tone thresholds were observed, and polymerase chain reaction-corrected cure rates were > 95% to Day 42. The results support the continued safe and efficacious use of artemether-lumefantrine in uncomplicated falciparum malaria. PMID:22232454

Although few studies address the use of three-phase bone scanning (TPBS) and indium-111-labeled white blood cell scintigraphy ({sup 111}In-WBC) in hip arthroplasty utilizing a porous-coated prosthesis, the literature suggests that scintigraphic patterns in the uncomplicated patient may differ from that seen with the cemented prosthesis. In an attempt to determine the scintigraphic natural history, 25 uncomplicated porous-coated hip arthroplasties in 21 patients were prospectively studied with serial TPBS and {sup 111I}n-WBC at approximately 7 days, and 3, 6, 12, 18, and 24 mo postoperatively. This report deals with findings related to the acetabulum. All 25 prostheses (144 of 144 scans)more » demonstrated increased uptake on the bone-phase images. Although this activity decreased with time, 76% had persistent uptake at 24 mo. Twenty-three of 25 prostheses (126 of 140 scans) showed increased uptake on {sup 111}In-WBC scintigraphy, invariably decreasing with time, but with 37% having significant uptake at 24 mo. Scintigraphic patterns in the uncomplicated porous-coated hip arthroplasty patient appear to differ from patterns described in cemented prostheses.« less

The aim of the study was to provide evidence-based recommendations for the management of early (uncomplicated) Parkinson's disease (PD), based on a review of the literature. Uncomplicated PD refers to patients suffering from the classical motor syndrome of PD only, without treatment-induced motor complications and without neuropsychiatric or autonomic problems. MEDLINE, Cochrane Library and International Network of Agencies for Health Technology Assessment (INAHTA) database literature searches were conducted. National guidelines were requested from all European Federation of Neurological Societies (EFNS) societies. Non-European guidelines were searched for using MEDLINE. Part I of the guidelines deals with prevention of disease progression, symptomatic treatment of motor features (parkinsonism), and prevention of motor and neuropsychiatric complications of therapy. For each topic, a list of therapeutic interventions is provided, including classification of evidence. Following this, recommendations for management are given, alongside ratings of efficacy. Classifications of evidence and ratings of efficacy are made according to EFNS guidance. In cases where there is insufficient scientific evidence, a consensus statement (good practice point) is made.

The efficacy of 3-day regimens of artemether-lumefantrine and artesunate-amodiaquine were evaluated in 747 children < 5 years of age with uncomplicated malaria from six geographical areas of Nigeria. Fever clearance was significantly faster (P = 0.006) and the proportion of children with parasitemia 1 day after treatment began was significantly lower (P = 0.016) in artesunate-amodiaquine—compared with artemether-lumefantrine-treated children. Parasite clearance times were similar with both treatments. Overall efficacy was 96.3% (95% confidence interval [CI] 94.5–97.6%), and was similar for both regimens. Polymerase chain reaction-corrected parasitologic cure rates on Day 28 were 96.9% (95% CI 93.9–98.2%) and 98.3% (95% CI 96.1–99.3%) for artemether-lumefantrine and artesunate-amodiaquine, respectively. Gametocyte carriage post treatment was significantly lower than pretreatment (P < 0.0001). In anemic children, mean time to recovery from anemia was 10 days (95% CI 9.04–10.9) and was similar for both regimens. Both treatments were well tolerated and are safe and efficacious treatments of uncomplicated falciparum malaria in young Nigerian children. PMID:25246693

Summary OBJECTIVES To assess the efficacy of amodiaquine-artesunate in an area with high chloroquine resistance in western Kenya. METHODS Twenty-eight day in-vivo efficacy trial of amodiaquine-artesunate in 103 children aged 6–59 months in western Kenya with smear-confirmed uncomplicated Plasmodium falciparum malaria. RESULTS The 28-day uncorrected adequate clinical and parasitological response (ACPR) was 69.0%, with 15.5% Late Clinical Failure and 15.5% Late Parasitologic Failure rates. The PCR-corrected 28-day ACPR was 90.2%. Clinical risk factors for recurrent infection (recrudescences and reinfections) were lower axillary temperature at enrolment and low weight-for-age Z-score. The presence of single nucleotide polymorphisms pfcrt 76T and pfmdr1 86Y at baseline was associated with increased risk of recurrent infections, both reinfections and recrudescences. CONCLUSION Although artemether-lumefantrine (Coartem®) is the first line ACT in Kenya, amodiaquine-artesunate is registered as an option for treatment of uncomplicated P. falciparum and remains an effective alternative to Coartem® in western Kenya. Continued amodiaquine monotherapy in the private sector may jeopardise the future use of amodiaquine-artesunate as an alternative artemisinin-based combination therapy. PMID:19187521

Objective: To assess adherence to malaria diagnosis and treatment guidelines (2010 and 2014) in all health care facilities in Swaziland between 2011 and 2015. Methods: This was a cross-sectional descriptive study involving all health care facilities that diagnosed and managed malaria cases in Swaziland. Patients' age, sex, diagnosis method and type of treatment were analysed. Results: Of 1981 records for severe and uncomplicated malaria analysed, 56% of cases were uncomplicated and 14% had severe malaria. The type of malaria was not recorded for 30% of cases. Approximately 71% of cases were confirmed by rapid diagnostic tests (RDT) alone, 3% by microscopy alone and 26% by both RDT and microscopy. Of the uncomplicated cases, 93% were treated with artemether-lumefantrine (AL) alone, 5% with quinine alone and 2% with AL and quinine. Amongst the severe cases, 11% were treated with AL alone, 44% with quinine alone and 45% with AL and quinine. For severe malaria, clinics and health centres prescribed AL alone more often than hospitals (respectively 13%, 12% and 4%, P = 0.03). Conclusion: RDTs and/or microscopy results are used at all facilities to inform treatment. Poor recording of malaria type causes difficulties in assessing the prescription of antimalarial drugs.

Dihydroartemisinin-piperaquine (DHA-PQ) is one of five WHO recommended artemisinin combination therapy (ACT) for the treatment of uncomplicated malaria. However, little was known on its post-registration safety and effectiveness in sub-Saharan Africa. DHA-PQ provides a long post-treatment prophylactic effect against re-infection; however, new infections have been reported within a few weeks of treatment, especially in children. This paper reports the clinical outcomes following administration of DHQ-PQ in real-life conditions in public health facilities in Burkina Faso, Ghana, Mozambique, and Tanzania for the treatment of confirmed uncomplicated malaria. An observational, non-comparative, longitudinal study was conducted on 10,591 patients with confirmed uncomplicated malaria visiting public health facilities within seven health and demographic surveillance system sites in four African countries (Ghana, Tanzania, Burkina Faso, Mozambique) between September 2013 and April 2014. Patients were treated with DHA-PQ based on body weight and followed up for 28 days to assess the clinical outcome. A nested cohort of 1002 was intensely followed up. Clinical outcome was assessed using the proportion of patients who reported signs and symptoms of malaria after completing 3 days of treatment. A total of 11,097 patients were screened with 11,017 enrolled, 94 were lost to follow-up, 332 withdrew and 10,591 (96.1%) patients aged 6 months-85 years met protocol requirements for analysis. Females were 52.8 and 48.5% were <5 years of age. Malaria was diagnosed by microscopy and rapid diagnostic test in 69.8% and 29.9%, respectively. At day 28, the unadjusted risk of recurrent symptomatic parasitaemia was 0.5% (51/10,591). Most of the recurrent symptomatic malaria patients (76%) were children <5 years. The mean haemoglobin level decreased from 10.6 g/dl on day 1 to 10.2 g/dl on day 7. There was no significant renal impairment in the nested cohort during the first 7 days of follow-up with minimal non-clinically significant changes noted in the liver enzymes. DHA-PQ was effective and well tolerated in the treatment of uncomplicated malaria and provides an excellent alternative first-line ACT in sub-Saharan Africa.

Purpose To examine whether family history of unprovoked seizures is associated with behavioral disorders in epilepsy probands, thereby supporting the hypothesis of shared underlying genetic susceptibility to these disorders. Methods We conducted an analysis of the 308 probands with childhood onset epilepsy from the Connecticut Study of Epilepsy with information on first degree family history of unprovoked seizures and of febrile seizures whose parents completed the Child Behavior Checklist (CBCL) at the 9-year follow-up. Clinical cut-offs for CBCL problem and DSM-Oriented scales were examined. The association between first degree family history of unprovoked seizure and behavioral disorders was assessed separately in uncomplicated and complicated epilepsy and separately for first degree family history of febrile seizures. A subanalysis, accounting for the tendency for behavioral disorders to run in families, adjusted for siblings with the same disorder as the proband. Prevalence ratios were used to describe the associations. Key findings In probands with uncomplicated epilepsy, first degree family history of unprovoked seizure was significantly associated with clinical cut-offs for Total Problems and Internalizing Disorders. Among Internalizing Disorders, clinical cut-offs for Withdrawn/Depressed, and DSM-Oriented scales for Affective Disorder and Anxiety Disorder were significantly associated with family history of unprovoked seizures. Clinical cut-offs for Aggressive Behavior and Delinquent Behavior, and DSM-Oriented scales for Conduct Disorder and Oppositional Defiant Disorder were significantly associated with family history of unprovoked seizure. Adjustment for siblings with the same disorder revealed significant associations for the relationship between first degree family history of unprovoked seizure and Total Problems and Agressive Behavior in probands with uncomplicated epilepsy; marginally significant results were seen for Internalizing Disorder, Withdrawn/Depressed and Anxiety Disorder. There was no association between family history of unprovoked seizure and behavioral problems in probands with complicated epilepsy. First degree family history of febrile seizure was not associated with behavioral problems in probands with uncomplicated or in those with complicated epilepsy. Significance Increased occurrence of behavioral disorders in probands with uncomplicated epilepsy and first degree family history of unprovoked seizure suggests familial clustering of these disorders. This supports the idea that behavioral disorders may be another manifestation of the underlying pathophysiology involved in epilepsy or closely related to it. PMID:22191626

The placenta is important in providing a healthy environment for the fetus and plays a central role in the pathophysiology of preeclampsia (PE). Fetal and placental developments are influenced by epigenetic programming. There is some evidence that PE is controlled to an altered circadian homeostasis. In a nested case-control study embedded in the Rotterdam Periconceptional Cohort, we obtained placental tissue, umbilical cord leukocytes (UCL), and human umbilical venous endothelial cells of 13 early-onset PE, 16 late-onset PE and 83 controls comprising 36 uncomplicated and 47 complicated pregnancies, i.e. 27 fetal growth restricted and 20 spontaneous preterm birth. To investigate the associations between PE and the epigenetics of circadian clock and clock-controlled genes in placental and newborn tissues, genome-wide DNA methylation analysis was performed using the Illumina HumanMethylation450K BeadChip and a candidate-gene approach using ANCOVA was applied on 939 CpGs of 39 circadian clock and clock-controlled genes. DNA methylation significantly differed in early-onset PE compared with spontaneous preterm birth at 6 CpGs in placental tissue (3.73 E-5 ≤ p ≤ 0.016) and at 21 CpGs in UCL (1.09 E-5 ≤ p ≤ 0.024). In early-onset PE compared with fetal growth restriction 2 CpGs in placental tissue (p < 0.05) and 8 CpGs in uncomplicated controls (4.78 E-5 ≤ p ≤ 0.049) were significantly different. Moreover, significantly different DNA methylation in early-onset PE compared with uncomplicated controls was shown at 6 CpGs in placental tissue (1.36 E-4 ≤ p ≤ 0.045) and 11 CpGs in uncomplicated controls (2.52 E-6 ≤ p ≤ 0.009). No significant associations were shown with late-onset PE between study groups or tissues. The most differentially methylated CpGs showed hypomethylation in placental tissue and hypermethylation in uncomplicated controls. In conclusion, DNA methylation of circadian clock and clock-controlled genes demonstrated most differences in UCL of early-onset PE compared with spontaneous preterm birth. Implications of the tissue-specific variations in epigenetic programming for circadian performance and long-term health need further investigation.

Background -There is controversy regarding outcome of patients with acute myocarditis (AM), and lack of data on how patients admitted with suspected AM are managed. We report characteristics, in-hospital management and long-term outcome of patients with AM based on a retrospective multi-center registry from 19 Italian hospitals. Methods -A total of 684 patients with suspected AM and recent onset of symptoms (<30 days) were screened between May 2001 and February 2017. Patients >70 years and those older than 50 years without coronary angiography were excluded. The final study population comprised 443 patients (median age 34 years, 19.4% female) with AM diagnosed either by endomyocardial biopsy (EMB) or increased troponin plus edema and late gadolinium enhancement at cardiac magnetic resonance (CMR). Results -At presentation, 118 patients (26.6%) had either left ventricular (LV) ejection fraction (EF) <50%, sustained ventricular arrhythmias (VA) or a low cardiac output syndrome (LCOS) whilst 325 (73.4%) had no such complications. EMB was performed in 56/443 (12.6%), and a baseline CMR was performed in 415/443 (93.7%) of patients. Cardiac mortality plus heart transplant (HTx) at 1 and 5 years were 3.0% and 4.1%. Cardiac mortality plus HTx were 11.3% and 14.7% in patients with complicated presentation and 0% in uncomplicated cases (Log-rank p<0.0001). Major AM-related cardiac events after the acute phase (post-discharge death and HTx, sustained VA treated with electrical shock or ablation, symptomatic heart failure needing device implantation) occurred in 2.8% at 5-year follow up, with a higher incidence in patients with complicated forms (10.8% vs. 0% in uncomplicated AM, Log-rank p<0.0001). Beta adrenoceptor blockers were the most frequently employed medications both in complicated (61.9%) and in uncomplicated forms (53.8%, p=0.18). After a median time of 196 days, 200 patients had follow-up CMR and 8/55 (14.5%) with complications at presentation had LVEF<50% compared with 1/145 (0.7%) of those with uncomplicated presentation. Conclusions -In this contemporary study, overall serious adverse events after AM were lower than previously reported. However, patients with LVEF<50%, VA or LCOS at presentation were at higher risk compared with uncomplicated cases that had a benign prognosis and low risk of subsequent LV systolic dysfunction.

Recurrent uncomplicated cystitis in women: allowing patients to self-initiate antibiotic therapy.

PubMed

2014-02-01

Acute uncomplicated cystitis is a lower urinary tract infection occurring in the absence of anatomic or functional abnormalities of the urinary tract or any other complicating factors.The organism responsible is often an enterobacterium, especially Escherichia coli. What is the role of antibiotic therapy for non-pregnant women with recurrent acute uncomplicated cystitis? We reviewed the available evidence using the standard Prescrire methodology. A single oral dose of fosfomycin trometamol is the antibiotic of choice for treating an episode of acute uncomplicated cystitis. Alternative antibiotics are certain fluoroquinolones or co-trimoxazole (a fixed-dose combination of sulfamethoxazole and trimethoprim). For recurrent acute uncomplicated cystitis, cranberry juice has modest efficacy in reducing the frequency of episodes. A number of non-drug measures are typically proposed, although their effects are unproven: drinking sufficient fluids and urinating regularly; urinating after sexual intercourse; and avoiding spermicides. The strategy that results in the lowest antibiotic exposure is a short course of antibiotics for each episode of urinary tract infection, initiated as soon as clinical symptoms appear. Long-term antibiotic therapy is sometimes offered. According to one systematic review, women taking long-term prophylactic antibiotic therapy had about 6 times fewer clinical recurrences than with placebo. According to one randomised trial, 3 g of fosfomycin trometamol taken as a single dose every ten days reduced the frequency of recurrence, resulting in 0.14 episodes of infection per year on average versus about 3 episodes with placebo (p < 0.001). The amount of antibiotic used when fosfomycin trometamol is taken every 10 days for 6 months is equivalent to treatment of 18 acute episodes of cystitis. When cystitis appears to be associated with sexual intercourse, two small randomised trials suggest that routine postcoital antibiotic treatment is more effective than placebo and as effective as long-term antibiotic therapy. Adverse effects, some of which can be serious, depend on the antibiotic used. The development of resistance among enterobacteria is one argument for limiting the use of antibiotics, in order to preserve their efficacy in serious infections. In practice, the strategy that uses the fewest antibiotics is to treat each episode as soon as the first clinical symptoms appear. Cases in which the frequency of recurrence warrants regular antibiotic prophylaxis are rare. The optimal antibiotic regimen in these cases has not been determined, either in clinical trials or by consensus.

High maternal mortality has remained an unmet public health challenge in the developing world. Maternal mortality in Ethiopia is among the highest in the world. Since most maternal deaths occur during labor, delivery, and the immediate postpartum period, facility delivery with skilled birth attendants is recommended to reduce maternal mortality. Nonetheless, the majority of women in Ethiopia give birth at home. Individual attributes and availability and accessibility of services deter service utilization. The role of social networks that may facilitate or constrain service use is not well studied. Community-based case-control study was conducted between February and March 2014 in Jabi Tehinan District, North West Ethiopia. Retrospective data were collected from 134 women who had uncomplicated births at health facilities and 140 women who had uncomplicated births at home within a year preceding the survey. Interviews were held with eight women who had uncomplicated births at health facilities and 11 who had uncomplicated births at home. The quantitative data were entered and analyzed using SPSS for Windows versions 16.0 and hierarchical logistic regression model was used for analysis. The qualitative data were transcribed verbatim and data were used to substantiate the quantitative data. The results indicated that social network variables were significantly associated with the use of health facilities for delivery. Taking social networks into account improved the explanation of facility use for delivery services over women's individual attributes. Women embedded within homogeneous network members (Adjusted OR 2.53; 95% CI: 1.26-5.06) and embedded within high SBA endorsement networks (Adjusted OR 7.97; 95% CI: 4.07-12.16) were more likely to deliver at health facilities than their counterparts. Women living in urban areas (Adjusted OR 3.32; 95% CI: 1.37-8.05) and had better knowledge of obstetric complications (Adjusted OR 3.01; 95% CI: 1.46-6.18) were more likely to deliver at health facilities. Social networks facilitate SBA utilization by serving as a reference for the behavior to deliver at health facilities. These findings inform health professionals and other stakeholders regarding the importance of considering women's social networks in designing intervention to increase the proportion of women who deliver at health facilities.

Malaria the first causes of death from parasitic infection worldwide. Interventions to reduce the burden of malaria have produced a tremendous drop in malaria morbidity and mortality. However, progress is slower in DRC, which shares with Nigeria 39% of deaths related to malaria globally. Inappropriate use of drugs may be one of the factors of this below-average performance. The aim of this study was to describe the use of drugs in the management of uncomplicated malaria in public health facilities in DRC. A drug use study was carried out in DRC from January to March 2014. In each of the former 11 provinces of DRC, one Rural Health Centre, one Urban Health Centre and one General Hospital were selected. In each of them, 100 patient's files containing prescription of anti-malarials from January to December 2013 were randomly selected. Among them, all of the files with diagnosis of uncomplicated malaria were included in this study. Prescribed anti-malarials, co-prescribed drugs and their indications were collected. Descriptive analyses were performed. A total of 2300 files out of 3300 (69.7%) concerned uncomplicated malaria and were included in analysis. Malaria treatment was initiated after a positive RDT or microscopy in 51.5% of cases, upon suspicion without requesting biological confirmation in 37% and despite negative results in 11%. Twenty-nine (29) different treatment regimens were used. The drugs recommended by the National Malaria Control Programme were used in 54.3% of cases (artesunate-amodiaquine 37.4% or artemether-lumefantrine 16.9%). The second most used anti-malarial was quinine (32.4%). Apart from anti-malarials, an average of 3.1 drugs per patient were prescribed, among which antibiotics (67.9%), analgesics and non-steroidal anti-inflammatory (NSAIDs) (all abbreviations to be explicated on first use) (70.6%), vitamins (29.1%), anaemia drugs, including blood transfusion (9.1%) and corticosteroids (5.7%), In 51.4% of cases there was no indication for the concomitant medication. Management of uncomplicated malaria in DRC is characterized by a low adherence to treatment policy, numerous treatment regimens, and abundant concomitant medication potentially harmful to the patient. This may contribute to the low performance of DRC in malaria control. Determinant of this irrational use of drugs need to be assessed in order to formulate and implement efficient corrective measures.

Abstract Nontraumatic musculoskeletal disorders are the main reason for presentation to the emergency department (ED), with rachialgia (back pain) being the most common reason to request medical assessment among them. This also generates the highest demand for reassessments due to poor pain control or onset of adverse reactions to the treatment prescribed in the initial assessment. A retrospective observational study based on usual clinical practice was conducted in patients attending the ED due to low back pain during a period of 24 months. The primary objective was to determine the demand for reassessments in the ED by these patients in the following 30 days, according to the type of therapeutic approach used in the initial assessment. A total of 732 patients who requested medical assessment due to back pain in the ED of our hospital were analyzed, 91 of whom were treated with tapentadol whereas 641 received another treatment. In the first month after the initial assessment, reassessments were less common in the tapentadol group; this difference was significant from days 8 to 15 (P = 0.001, odds ratio [OR] 0.252 with 95% confidence interval [CI] 0.100–0.635) and days 15 to 30 (P < 10−4, OR 0.277 with 95% CI 0.136–0.563). Patients who received tapentadol also had a better clinical evolution of pain compared to those who did not receive it (P < 10−4) and to those who received tramadol (P < 10−4). In this study in patients with back pain, tapentadol shows clear advantages over the other analgesics analyzed, in terms of pain control and less need for reassessments. PMID:29137025

The association between celiac disease and eating disorders has been very rarely reported. This is the first report on celiac disease associated with bulimia in this part of Europe. An adult female patient with history of bulimia and one uncomplicated pregnancy was admitted to the Gastroenterology Department, due to long lasting dyspeptic symptoms, constipation, major weight loss and fatigue. After positive serological screening, the diagnosis of celiac disease was confirmed with histopathology examination of duodenal biopsy specimen. Complicated interactions between celiac disease and bulimia can make them difficult to diagnose and treat. It is important to consider the presence of celiac disease in patients with bulimia and gastrointestinal symptoms.

Background: Increasing morbidity and mortality of Asthma placed it among the most dreaded diseases. Prediction says that asthma along with chronic obstructive pulmonary disease become third leading cause of death by the year 2020. Despite the availability of a wide range of antiasthmatic drugs, incidence of asthma is increasing alarmingly because the relief offered by these drugs is mainly symptomatic and short-lived. Moreover, their side effects are also quite distressing. Hence, a continuous search is needed to identify effective and safe remedies to treat bronchial asthma. Aims: The present clinical study was conducted to evaluate the efficacy of Shirishadi Polyherbal compound (given through nebulizer in Aerosol form) in the management of acute and chronic uncomplicated Bronchial Asthma and to propose a novel and safer Ayurvedic treatment modality. Methods and Materials: It is a randomized, open, control clinical trial in which the effect of the drug was compared with contemporary treatment and placebo medication (normal saline) in 60 adults with mild to moderate asthma. Results: There was a (t>0.001) found in pulmonary function tests (including FEV1, FVC and PEFR)in the group treated with polyherbal drug. Improvement remain constant in consecutive follow-ups signifies that there is no reverse broncho-constriction after discontinuation of the drug. Conclusion: This study signifies that polyherbal drug - Shirishadi compound may prove beneficial future alternative remedy for asthma, and its effect is similar to that of modern contemporary drug when given through nasal route.

A 5-year-old 8.6-kg (18.9-lb) spayed female Pug was evaluated because of chronic hematuria and recurrent urinary tract infections. Excretory urography, ultrasonography, and excretory CT urography were performed. Results indicated that the dog had bilateral hydronephrosis and hydroureter and suspected proximal ureteral stenosis. Retrograde ureteropyelography confirmed the presence of stenosis at the ureteropelvic junction of each ureter, along with a large amount of endoluminal ureteral debris. Clinical findings suggested that the dog had a congenital bilateral anomaly of the upper urinary tract. The dog was anesthetized, and 2 double-pigtail ureteral stents were placed cystoscopically with fluoroscopic guidance for immediate relief of the ureteropelvic junction obstructions. Each stent extended from the left or right renal pelvis to the urinary bladder. The procedures and the patient's recovery from anesthesia were uncomplicated. Continuing improvements in severity of hydronephrosis, hydroureter, and dysuria were evident during routine follow-up examinations at 2, 4, 12, 16, and 45 weeks after stent placement. Over the subsequent 12 months, all clinical signs remained resolved other than a urinary tract infection that was successfully treated with antimicrobials. Ureteral stenosis should be considered as a differential diagnosis for hydronephrosis in dogs, particularly when urinary tract calculi or neoplasia is not present. Chronic hematuria and recurrent urinary tract infections can be associated with this condition. Placement of ureteral stents may be a successful treatment option for ameliorization of congenital ureteral obstructions.

Ulcerative colitis (UC) is a chronic inflammatory disease, whose etiology is still unclear. Its pathogenesis involves an interaction between genetic factors, immune response and the “forgotten organ”, Gut Microbiota. Several studies have been conducted to assess the role of antibiotics and probiotics as additional or alternative therapies for Ulcerative Colitis. Escherichia coli Nissle (EcN) is a nonpathogenic Gram-negative strain isolated in 1917 by Alfred Nissle and it is the active component of microbial drug Mutaflor® (Ardeypharm GmbH, Herdecke, Germany and EcN, Cadigroup, In Italy) used in many gastrointestinal disorder including diarrhea, uncomplicated diverticular disease and UC. It is the only probiotic recommended in ECCO guidelines as effective alternative to mesalazine in maintenance of remission in UC patients. In this review we propose an update on the role of EcN 1917 in maintenance of remission in UC patients, including data about efficacy and safety. Further studies may be helpful for this subject to further the full use of potential of EcN. PMID:27350728

Diverticular Disease: An Update on Pathogenesis and Management

PubMed Central

Rezapour, Mona; Ali, Saima

2018-01-01

Diverticular disease is one of the most common conditions in the Western world and one of the most common findings identified at colonoscopy. Recently, there has been a significant paradigm shift in our understanding of diverticular disease and its management. The pathogenesis of diverticular disease is thought to be multifactorial and include both environmental and genetic factors in addition to the historically accepted etiology of dietary fiber deficiency. Symptomatic uncomplicated diverticular disease (SUDD) is currently considered a type of chronic diverticulosis that is perhaps akin to irritable bowel syndrome. Mesalamine, rifaximin and probiotics may achieve symptomatic relief in some patients with SUDD, although their role(s) in preventing complications remain unclear. Antibiotic use for acute diverticulitis and elective prophylactic resection surgery are considered more individualized treatment modalities that take into account the clinical status, comorbidities and lifestyle of the patient. Our understanding of the pathogenesis of diverticular disease continues to evolve and is likely to be diverse and multifactorial. Paradigm shifts in several areas of the pathogenesis and management of diverticular disease are explored in this review. PMID:28494576

Treatment of sternal nonunion with the Dall-Miles cable system.

Eich, B S; Heinz, T R

2000-10-01

We have used this technique in two patients. One had early sternal dehiscence with presternal infection, and the other had late sternal nonunion. Uncomplicated sternal union was achieved in both patients. The cables were nonpalpable in both patients, but they were removed in one patient at that patient's request. This method of using Dall-Miles cerclage cables is a straightforward and efficacious method of open reduction and internal fixation of the sternum. It is indicated for patients with chronic sternal nonunion or early postoperative separation of the sternal fragments and may be used even in the presence of an infection limited to the presternal space after adequate debridement and irrigation have been performed. Any recurrent superficial infection, although unlikely, can be cured by hardware removal after osseous union has been obtained. For sternal separation without fractures, four cables may simply be placed around the sternal halves and their tension increased. In the case of sternal fractures, the cables may be placed in figures of eight or in other woven configurations as needed for each individual case.

To describe community health workers (CHWs) roles in a diabetes self-management intervention. Retrospective qualitative inductive analysis of open text home visit encounter form from Peer Support for Achieving Independence in Diabetes (Peer AID), a randomized controlled trial in which low-income individuals with poorly controlled diabetes received either CHW home visits or usual care. Following visits, CHWs completed encounter forms documenting the health goal of the visit, the self-management strategies discussed and participant concerns. 634 encounter reports were completed for the 145 intervention participants. CHW notes revealed three main obstacles to optimal disease control: gaps in diabetes knowledge and self-management skills; socioeconomic conditions; and the complexity of the healthcare system. CHWs helped participants overcome these obstacles through extensive, hands-on education, connecting participants to community resources, and assistance navigating the medical system. In addition, the CHWs offered uncomplicated accessibility and availability to their clients.

After laparoscopic cholecystectomy, the duration of convalescence is 2 to 3 weeks with an unclear pathogenesis. This study was undertaken to analyze postoperative recovery after uncomplicated elective laparoscopic cholecystectomy. Twenty-four consecutive unselected employed patients were followed up prospectively from 1 week before to 1 week after outpatient laparoscopic cholecystectomy. Daily computerized monitoring of physical motor activity and sleep duration and night sleep fragmentation (actigraphy), subjective sleep quality, pulmonary function, pain, and fatigue were registered. Treadmill exercise performance (preoperatively and at postoperative days 2 and 8) and nocturnal pulse oximetry at the patients' homes (preoperatively and postoperative nights 1-3) were completed. Median age was 41 years (range, 21-56). Compared with preoperatively, levels of physical motor activity, fatigue, and pain scores were normalized 2 days after operation. Subjective sleep quality was significantly worsened on the first postoperative night, and sleep duration was significantly increased on the first 2 postoperative nights. There were no significant perioperative changes in actigraphy night sleep fragmentation, incidence of self-reported awakenings or nightmares/distressing dreams, exercise performance, or nocturnal oxygenation. Pulmonary peak flow measurements were normalized the day after operation. After uncomplicated outpatient laparoscopic cholecystectomy, there is no pathophysiologic basis for recommending a postoperative convalescence of more than 2 to 3 days in otherwise healthy younger patients.

Most urinary tract infections (UTI) are uncomplicated infections occurring in young women. An extensive evaluation is not required in the majority of cases, and they can be safely managed as outpatients with oral antibiotics. Escherichia coli is by far the most common uropathogen, accounting for >80% of all cases. Other major clinical problems associated with UTI include asymptomatic bacteriuria, and patients with complicated UTI. Complicated UTIs are a heterogeneous group associated with conditions that increase the risk of acquiring infection or treatment failure. Distinguishing between complicated and uncomplicated UTI is important, as it influences the initial evaluation, choice, and duration of antimicrobial therapy. Diagnosis is especially challenging in the elderly and in patients with in-dwelling catheters. The increasing prevalence of resistant uropathogens, including extended-spectrum β-lactamases and carbapenemase-producing Enterobacteriaceae, and other multidrug-resistant Gram-negative organisms further compromises treatment of both complicated and uncomplicated UTIs. The aim of these Clinical Guidelines is to provide a set of recommendations for improving the diagnosis and treatment of UTI.

We studied 135 people (24 people, apparently healthy, 39 uncomplicated peptic ulcer disease, 42 people with complex forms peptic ulcer, 30 and after the treatment of complicated forms of peptic ulcer disease, both sexes (18-45 y.). In all patients, the diagnosis was confirmed fibrogastroduodenoscopy (EGD). Determination of histones and acid soluble fraction (ASF), RNA, DNA, in blood was performed by the method of L. Markusheva. Studies have led to the conclusion that the change in the blood concentration of extracellular nucleic acids in patients with uncomplicated disease and complex shapes can be caused by oxidative stress products and can be a signal for elimination of nucleic acids from cells. We have registered various dynamics of the studied parameters histones in the blood of patients with various forms of peptic ulcer disease, which reflects the degree of metabolic abnormalities that occur in the body, associated with changes in the structure of the nucleus. According to the results of our research in the study of the role of extracellular nucleic acids, histones to assess the extent of violations of metabolic processes at a peptic ulcer, complicated and uncomplicated form, the obtained results can be used as predictors of complications of a stomach ulcer.

Appendicitis is the most common gastrointestinal pediatric surgical emergency. With the introduction of laparoscopic techniques in the 1990s, recovery, pain, and hospital stay after laparoscopic procedures have been significantly reduced. While many laparoscopic procedures are performed as outpatient surgeries, pediatric appendectomy patients continue to be hospitalized for postoperative observation. Our goal was to evaluate the safety and feasibility of same day discharge after laparoscopic appendectomy for uncomplicated appendicitis. After IRB approval, all pediatric patients undergoing laparoscopic appendectomy during 2016 for noncomplicated appendicitis were eligible for the study. Decision for same day discharge was based on surgeon preference and parental agreement. Data regarding demographics, admission and discharge times, outcomes of complications, readmissions, return to the ED, and nonscheduled clinic visits were collected. A total of 1321 appendectomies were performed during the study period, of which 849 were uncomplicated and 382 were discharged same day. There were 2 readmissions, 4 superficial surgical site infections, 10 patients with nausea or vomiting, and 33 patients with pain control issues, 9 of whom presented to the ED. Same day discharge for laparoscopic noncomplicated appendectomy is a safe and feasible alternative to postoperative admission and observation. This has the potential to yield significant healthcare cost savings. Level II, Prospective Cohort Study. Copyright © 2018. Published by Elsevier Inc.

Quality of life (QoL) is becoming a major issue in the evaluation of any therapeutic intervention. To assess the QoL in patients with uncomplicated symptomatic diverticular disease (DD) and to elucidate the influence of two different treatments either on symptoms or QoL. 58 outpatients affected by uncomplicated symptomatic DD, admitted in our Gastroenterological Unit from October 2003 to March 2004, were enrolled. Patients were randomly assigned to two different treatments consisting of rifaximin or mesalazine for 10 days every month for a period of 6 months. QoL was evaluated by means of an SF-36 questionnaire and clinical evaluation was registered by means of a global symptomatic score (GSS) at baseline and after 6 months. At baseline, lower values in all SF-36 domains were confirmed in patients with DD. Both rifaximin and mesalazine groups showed a significant reduction of their mean GSS (p < 0.01 and p < 0.001, respectively) and improvement of SF-36 mean scores after therapy, even though treatment with mesalazine showed better results. DD has a negative impact on QoL. Cyclic treatment with poorly absorbable antibiotics or anti-inflammatory drugs relieves symptoms and improves QoL. 2007 S. Karger AG, Basel

Many medications are available for scabies treatment including oral and topical ivermectin. However, studies comparing these two forms as a scabies treatment are few. This study compares efficacy and safety of topical versus oral ivermectin as scabies treatment. The study included 62 confirmed uncomplicated scabies patients, divided into: Group I (32 patients, received topical ivermectin) and Group II (30 patients, received oral ivermectin). Patients were assessed, clinically and by KOH smear at 1, 2 and 4 weeks. Treatment was repeated after one week in patients with persistent infection. Adverse events were recorded. Most patients (87.5% and 73.5% in group I and group II respectively) were symptom free after a single treatment. A second treatment was required in 4 patients of group I and 8 patients of group II. However, 2 weeks after treatment symptoms and signs completely resolved in all cases with no recurrence at 4 weeks. This study suggests that both topical and oral ivermectin are safe and equally effective in treatment of uncomplicated scabies. Single treatment, whether topical or oral, is associated with high cure rate in a week post treatment. However, repeating treatment after one week may be required to achieve 100% cure. © 2015 Wiley Periodicals, Inc.

Autosomal recessive polycystic kidney disease (ARPKD) is the most common childhood-onset ciliopathy. As treatments improve, more women are reaching reproductive age, but little is known about ARPKD and pregnancy. In our ongoing study on ARPKD and other ciliopathies, 12 females over 18 years of age were identified and systematically evaluated. Six had children; four carried pregnancies and delivered, one used assisted reproductive technology and had a surrogate carry the pregnancy, and one adopted. We report the outcomes of four pregnancies with live birth deliveries and two women who chose alternate family building options. Patient one was diagnosed at 6 months, and at age 21 had a pregnancy complicated by transient worsening of renal function (creatinine increase from 1.15 to 1.78 mg/dL). Patient two was diagnosed with ARPKD at age seven and had an uncomplicated pregnancy at age 23. Patient three was diagnosed incidentally with ARPKD at age 23, 3 months after completion of an uncomplicated pregnancy. Patient four who had an uncomplicated pregnancy at age 33 was diagnosed with ARPKD at age 46. Women with ARPKD face reproductive decisions largely bereft of information about the pregnancies of other ARPKD patients. We report four cases of pregnancy and ARPKD to expand current knowledge and encourage further research.

The first randomized multicenter study evaluating the need for antibiotic treatment in patients with acute uncomplicated diverticulitis (AUD) could not demonstrate any benefit gained from antibiotic use. The aim of this study was to review the application of the no antibiotic policy and its consequences in regard to complications and recurrence. This retrospective population-based cohort study included all patients diagnosed with all types of colonic diverticulitis during the year 2011 at Västmanland Hospital Västerås, Sweden. All medical records were carefully reviewed. Primary outcomes were the types of treatment adopted for diverticulitis, complications and recurrence. In total, 246 patients with computer tomography-verified diverticulitis were identified, 195 with primary AUD and 51 with acute complicated diverticulitis. Age, sex, and temperature at admission were similar between the groups but there was a significant difference in white blood cell count, C-reactive protein, and length of hospital stay. In the AUD group, 178 (91.3%) patients were not treated with antibiotics. In this group, there were six (3.4%) readmissions but only two developed an abscess. Of the remaining 17 patients (8.7%) who were treated with antibiotics in the AUD group, one developed an abscess. Twenty-five (12.8%) patients in the AUD group presented with a recurrence within 1 year. The no-antibiotic policy for AUD is safe and applicable in clinical practice. The previous results of a low complication and recurrence rate in AUD are confirmed. There is no need for antibiotic treatment for AUD. What does this paper add to the literature? Despite published papers with excellent results, there are still doubts about patient safety against the policy to not use antibiotics in acute uncomplicated diverticulitis. This is the first paper, in actual clinical practice, to confirm that the no antibiotic policy for acute uncomplicated diverticulitis is applicable and safe.

Artemisinin-based combination therapies (ACTs) are highly efficacious and safe, but data from human immunodeficiency virus (HIV)-infected children concurrently receiving antiretroviral therapy (ART) and ACTs are limited. We evaluated 28-day outcomes following malaria treatment with artemether-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP) in 2 cohorts of HIV-infected Ugandan children taking various ART regimens. In one cohort, children <6 years of age were randomized to lopinavir/ritonavir (LPV/r) or nonnucleoside reverse transcriptase inhibitor-based ART and treated with AL for uncomplicated malaria. In another cohort, children <12 months of age were started on nevirapine-based ART if they were eligible, and randomized to AL or DP for the treatment of their first and all subsequent uncomplicated malaria episodes. There were 773 and 165 treatments for malaria with AL and DP, respectively. Initial response to therapy was excellent, with 99% clearance of parasites and <1% risk of repeat therapy within 3 days. Recurrent parasitemia within 28 days was common following AL treatment. The risk of recurrent parasitemia was significantly lower among children taking LPV/r-based ART compared with children taking nevirapine-based ART following AL treatment (15.3% vs 35.5%, P = .009), and those treated with DP compared with AL (8.6% vs 36.2%, P < .001). Both ACT regimens were safe and well tolerated. Treatment of uncomplicated malaria with AL or DP was efficacious and safe in HIV-infected children taking ART. However, there was a high risk of recurrent parasitemia following AL treatment, which was significantly lower in children taking LPV/r-based ART compared with nevirapine-based ART. © The Author 2014.

Objective To examine the between-hospital variation of charges and discounted prices for uncomplicated vaginal and caesarean section deliveries, and to determine the institutional and market-level characteristics that influence adjusted charges. Design, setting and participants Using data from the California Office of Statewide Health Planning and Development (OSHPD), we conducted a cross-sectional study of all privately insured patients admitted to California hospitals in 2011 for uncomplicated vaginal delivery (diagnosis-related group (DRG) 775) or uncomplicated caesarean section (DRG 766). Outcome measures Hospital charges and discounted prices adjusted for each patient's clinical and demographic characteristics. Results We analysed 76 766 vaginal deliveries and 32 660 caesarean sections in California in 2011. After adjusting for patient demographic and clinical characteristics, we found that the average California woman could be charged as little as US$3296 or as much as US$37 227 for a vaginal delivery, and US$8312–US$70 908 for a caesarean section depending on which hospital she was admitted to. The discounted prices were, on an average, 37% of the charges. We found that hospitals in markets with middling competition had significantly lower adjusted charges for vaginal deliveries, while hospitals with higher wage indices and casemixes, as well as for-profit hospitals, had higher adjusted charges. Hospitals in markets with higher uninsurance rates charged significantly less for caesarean sections, while for-profit hospitals and hospitals with higher wage indices charged more. However, the institutional and market-level factors included in our models explained only 35–36% of the between-hospital variation in charges. Conclusions These results indicate that charges and discounted prices for two common, relatively homogeneous diagnosis groups—uncomplicated vaginal delivery and caesarean section—vary widely between hospitals and are not well explained by observable patient or hospital characteristics.

Pneumonia is the most important respiratory problem in low-to-middle income countries. Airway clearance therapy continues to be used in children with pneumonia and secretion retention; however, there is lack of evidence to support or reject this treatment. This study aimed to investigate the feasibility of a randomized controlled trial (RCT) on the efficacy and safety of assisted autogenic drainage (AAD) compared to standard nursing care in children hospitalized with uncomplicated pneumonia. A single-blinded pilot RCT was conducted on 29 children (median age 3.5 months, IQR 1.5-9.4) hospitalized with uncomplicated pneumonia. The intervention group received standard nursing care with additional bi-daily AAD, for 10 to 30 min. The control group only received standard nursing care, unless otherwise deemed necessary by the physician or physiotherapist. The primary outcome measure was duration of hospitalization. The secondary outcome measures included days of fever and supplemental oxygen support; respiratory rate (RR) and heart rate adjusted for age; RR and oxygen saturation pre-, post-, and 1-hr post-treatment; oxygen saturation; adverse events; and mortality. No difference was found for duration of hospitalization (median 7.5 and 7.0 days for the control and intervention groups, respectively); however, Kaplan-Meier analysis revealed a strong tendency towards a shorter time to discharge in the intervention group (p = .06). No significant differences were found for the other outcome measures at time of discharge. No adverse events were reported. Within the intervention group, a significant reduction in RR adjusted for age was found. As no adverse events were reported, and AAD did not prolong hospitalization; AAD might be considered as safe and effective in young children with uncomplicated pneumonia. However, a larger multicentred RCT is warranted to determine the efficacy of AAD compared to standard nursing care. Copyright © 2017 John Wiley & Sons, Ltd.

Transmural stents are placed at endoscopy to drain pancreatic fluid collections. This study evaluated the relationship between stent placement and treatment outcomes in patients undergoing endoscopic transmural drainage of uncomplicated pancreatic pseudocysts. This is a retrospective study of all patients who underwent endoscopic drainage of uncomplicated pancreatic pseudocysts over a 10-year period. After dilating the transmural tracts in the range of 8-15 mm, single or multiple, 7 or 10Fr double-pigtail plastic stents were deployed. The main outcome measure was to evaluate the relationship between stent characteristics and the number of endoscopic interventions required to achieve resolution of the pancreatic pseudocyst (treatment success). Of 122 patients, 45 (36.9%) had 10Fr stents of which 30 patients (66.7%) had more than one stent; the remaining 77 (63.1%) patients had 7Fr stents of which 56 (72.7%) had more than one stent. The overall treatment success was 94.3%. Treatment was successful in 102 patients (83.6%) with one intervention; 13 patients (10.7%) required re-intervention for successful drainage and 7 patients (5.7%) failed endoscopic treatment. There was no significant difference in the number of interventions required for treatment success between patients with 7 or 10Fr stents (one intervention required in 87.7 vs. 90.5%, respectively; p = 0.766) and between patients with 1 or >1 stent (one intervention required in 88.9 vs. 88.6%, respectively; p = 0.999). On multiple logistic regression analysis, the stent size (OR 1.54; 95% CI 0.23-10.4) and number (OR 1.15; 95% CI 0.25-5.25) were not associated with the number of interventions required for treatment success when adjusted for pseudocyst size, location, drainage modality, the presence or absence of pancreatic duct stent and luminal compression. There appears to be no relationship between the number of interventions required for treatment success and stent characteristics in patients undergoing endoscopic transmural drainage of uncomplicated pancreatic pseudocysts.

Background Current (1999) World Health Organization guidelines recommend giving routine antibiotics (AB) for all children with severe acute malnutrition (SAM), even if they have uncomplicated disease with no clinically obvious infections. We examined the evidence behind this recommendation. Methods and Findings OVID-MEDLINE, EMBASE, COCHRANE, GLOBAL-HEALTH, CINAHL, POPLINE, AFRICA-WIDE-NiPAD, and LILACS were searched for AB efficacy, bacterial resistance, and infection rates in SAM. Following PRISMA guidelines, a systematic review and meta-analysis were performed. Three randomised controlled trials (RCT), five Cochrane reviews, and 37 observational studies were identified. One cohort-study showed no increase in nutritional-cure and mortality in uncomplicated SAM where no AB were used. (p>0.05). However, an unpublished RCT in this setting did show mortality benefits. Another RCT did not show superiority of ceftriaxone over amoxicilllin for these same outcomes, but adressed SAM children with and without complications (p = 0.27). Another RCT showed no difference between amoxicillin and cotrimoxazole efficacies for pneumonia in underweight, but not SAM. Our meta-analysis of 12 pooled susceptibility-studies for all types of bacterial isolates, including 2767 stricly SAM children, favoured amoxicillin over cotrimoxazole for susceptibility medians: 42% (IQR 27–55%) vs 22% (IQR 17–23%) and population-weighted-means 52.9% (range 23–57%) vs 35.4% (range 6.7–42%). Susceptibilities to second-line AB were better, above 80%. Prevalence of serious infections in SAM, pooled from 24 studies, ranged from 17% to 35.2%. No study infered any association of infection prevalence with AB regimens in SAM. Conclusions The evidence underlying current antibiotic recommendations for uncomplicated SAM is weak. Susceptibility-studies favour amoxicillin over cotrimoxazole. However, given that these antibiotics have side-effects, costs, and risks as well as benefits, their routine use needs urgent testing. With reliable monitoring, we believe that there is sufficient equipoise for placebo controlled RCTs, the only robust way to demonstrate true efficacy. PMID:23326395

Mind the gap: knowledge and practice of providers treating uncomplicated malaria at public and mission health facilities, pharmacies and drug stores in Cameroon and Nigeria

Background Artemisinin combination therapy (ACT) has been the first-line treatment for uncomplicated malaria in Cameroon since 2004 and Nigeria since 2005, though many febrile patients receive less effective antimalarials. Patients often rely on providers to select treatment, and interventions are needed to improve providers’ practice and encourage them to adhere to clinical guidelines. Methods Providers’ adherence to malaria treatment guidelines was examined using data collected in Cameroon and Nigeria at public and mission facilities, pharmacies and drug stores. Providers’ choice of antimalarial was investigated separately for each country. Multilevel logistic regression was used to determine whether providers were more likely to choose ACT if they knew it was the first-line antimalarial. Multiple imputation was used to impute missing data that arose when linking exit survey responses to details of the provider responsible for selecting treatment. Results There was a gap between providers’ knowledge and their practice in both countries, as providers’ decision to supply ACT was not significantly associated with knowledge of the first-line antimalarial. Providers were, however, more likely to supply ACT if it was the type of antimalarial they prefer. Other factors were country-specific, and indicated providers can be influenced by what they perceived their patients prefer or could afford, as well as information about their symptoms, previous treatment, the type of outlet and availability of ACT. Conclusions Public health interventions to improve the treatment of uncomplicated malaria should strive to change what providers prefer, rather than focus on what they know. Interventions to improve adherence to malaria treatment guidelines should emphasize that ACT is the recommended antimalarial, and it should be used for all patients with uncomplicated malaria. Interventions should also be tailored to the local setting, as there were differences between the two countries in providers’ choice of antimalarial, and who or what influenced their practice.

This randomized, open-label study was conducted to establish the non-inferiority of a combination of azithromycin (AZ) and chloroquine (CQ) to artemether-lumefantrine (AL) for treatment of uncomplicated malaria in children from six sites in sub-Saharan Africa. Children with uncomplicated Plasmodium falciparum malaria between six and 59 months of age were randomized 1:1 to either AZCQ (30 mg/kg AZ + 10 mg/kg CQ base) or AL per prescribing information for three days (Days 0, 1, 2). Each site could enrol in the study population once the treatment of uncomplicated malaria in five children five to 12 years of age was deemed to be effective and well tolerated. The primary efficacy evaluation was the proportion of subjects in both the modified intent-to-treat (MITT) and per-protocol (PP) populations with an adequate clinical and parasitological response (PCR corrected) at Day 28. Non-inferiority was concluded if the lower bound of the 95% confidence interval comparing the two groups was 10 percentage points or greater. A total of 255 children were enrolled in the efficacy analysis (AZCQ, n = 124; AL, n = 131). The PCR corrected clearance rates were 89% (AZCQ) versus 98% (AL) for MITT, a difference of -9.10 (95% confidence interval; -16.02, -2.18) and 93% (AZCQ) versus 99% (AL) for PP, a difference of -6.08 (-12.10, -0.05). Early and late treatment failures were more common in subjects receiving AZCQ. Adverse events were more common in subjects treated with AZCQ. Drug concentrations obtained at specified time points following AZCQ administration had a large coefficient of variation partially due to sparse sampling with sample collection time window. In this study, non-inferiority of AZCQ to AL was not demonstrated. ClinicalTrials.gov NCT00677833 .

Study question Can treatment of the symptoms of uncomplicated urinary tract infection (UTI) with ibuprofen reduce the rate of antibiotic prescriptions without a significant increase in symptoms, recurrences, or complications? Methods Women aged 18-65 with typical symptoms of UTI and without risk factors or complications were recruited in 42 German general practices and randomly assigned to treatment with a single dose of fosfomycin 3 g (n=246; 243 analysed) or ibuprofen 3×400 mg (n=248; 241 analysed) for three days (and the respective placebo dummies in both groups). In both groups additional antibiotic treatment was subsequently prescribed as necessary for persistent, worsening, or recurrent symptoms. The primary endpoints were the number of all courses of antibiotic treatment on days 0-28 (for UTI or other conditions) and burden of symptoms on days 0-7. The symptom score included dysuria, frequency/urgency, and low abdominal pain. Study answer and limitations The 248 women in the ibuprofen group received significantly fewer course of antibiotics, had a significantly higher total burden of symptoms, and more had pyelonephritis. Four serious adverse events occurred that lead to hospital referrals; one of these was potentially related to the trial drug. Results have to be interpreted carefully as they might apply to women with mild to moderate symptoms rather than to all those with an uncomplicated UTI. What this paper adds Two thirds of women with uncomplicated UTI treated symptomatically with ibuprofen recovered without any antibiotics. Initial symptomatic treatment is a possible approach to be discussed with women willing to avoid immediate antibiotics and to accept a somewhat higher burden of symptoms.

As agents for their patients, providers often make treatment decisions on behalf of patients, and their choices can affect health outcomes. However, providers operate within a network of relationships and are agents not only for their patients, but also other health sector actors, such as their employer, the Ministry of Health, and pharmaceutical suppliers. Providers' stated preferences for the treatment of uncomplicated malaria were examined to determine what factors predict their choice of treatment in the absence of information and institutional constraints, such as the stock of medicines or the patient's ability to pay. 518 providers working at non-profit health facilities and for-profit pharmacies and drug stores in Yaoundé and Bamenda in Cameroon and in Enugu State in Nigeria were surveyed between July and December 2009 to elicit the antimalarial they prefer to supply for uncomplicated malaria. Multilevel modelling was used to determine the effect of financial and non-financial incentives on their preference, while controlling for information and institutional constraints, and accounting for the clustering of providers within facilities and geographic areas. 69% of providers stated a preference for artemisinin-combination therapy (ACT), which is the recommended treatment for uncomplicated malaria in Cameroon and Nigeria. A preference for ACT was significantly associated with working at a for-profit facility, reporting that patients prefer ACT, and working at facilities that obtain antimalarials from drug company representatives. Preferences were similar among colleagues within a facility, and among providers working in the same locality. Knowing the government recommends ACT was a significant predictor, though having access to clinical guidelines was not sufficient. Providers are agents serving multiple principals and their preferences over alternative antimalarials were influenced by patients, drug company representatives, and other providers working at the same facility and in the local area. Efforts to disseminate drug policy should target the full range of actors involved in supplying drugs, including providers, employers, suppliers and local communities. Copyright © 2014 The Authors.

A recent randomized trial showed that artemisinin-naphthoquine (AN) was non-inferior to artemether-lumefantrine (AL) for falciparum malaria and superior for vivax malaria in young Papua New Guinean children. The aim of this study was to compare the cost-effectiveness of these two regimens. An incremental cost-effectiveness analysis was performed using data from 231 children with Plasmodium falciparum and/or Plasmodium vivax infections in an open-label, randomized, parallel-group trial. Recruited children were randomized 1:1 to receive once daily AN for 3 days with water or twice daily AL for 3 days given with fat. World Health Organisation (WHO) definitions were used to determine clinical/parasitological outcomes. The cost of transport between the home and clinic, plus direct health-care costs, served as a basis for determining each regimen's incremental cost per incremental treatment success relative to AL by Day 42 and its cost per life year saved. In the usual care setting, AN was more effective for the treatment of uncomplicated malaria in children aged 0.5-5.9 years. AL and AN were equally efficacious for the treatment of falciparum malaria, however AN had increased anti-malarial treatment costs per patient of $10.46, compared with AL. AN was the most effective regimen for treatment of vivax malaria, but had increased treatment costs of $14.83 per treatment success compared with AL. Whilst AN has superior overall efficacy for the treatment of uncomplicated malaria in PNG children, AL was the less costly regimen. An indicative extrapolation estimated the cost per life year saved by using AN instead of AL to treat uncomplicated malaria to be $12,165 for girls and $12,469 for boys (discounted), which means AN may not be cost-effective and affordable for PNG at current cost. However, AN may become acceptable should it become WHO prequalified and/or should donated/subsidized drug supply become available.

Malaria and HIV infections are both highly prevalent in sub-Saharan Africa, with HIV-infected patients being at higher risks of acquiring malaria. The majority of antiretroviral (ART) and anti-malarial drugs are metabolized by the CYP450 system, creating a chance of drug-drug interaction upon co-administration. Limited data are available on the effectiveness of the artemether-lumefantrine combination (AL) when co-administered with non-nucleoside reverse transcriptase inhibitors (NNRTIs). The aim of this study was to compare anti-malarial treatment responses between HIV-1 infected patients on either nevirapine- or efavirenz-based treatment and those not yet on ART (control-arm) with uncomplicated falciparum malaria, treated with AL. This was a prospective, non-randomized, open-label study conducted in Bagamoyo district, with three arms of HIV-infected adults: efavirenz-based treatment arm (EFV-arm) n = 66, nevirapine-based treatment arm (NVP-arm) n = 128, and control-arm n = 75, with uncomplicated malaria. All patients were treated with AL and followed up for 28 days. The primary outcome measure was an adequate clinical and parasitological response (ACPR) after treatment with AL by day 28. Day 28 ACPR was 97.6%, 82.5% and 94.5% for the NVP-arm, EFV-arm and control-arm, respectively. No early treatment or late parasitological failure was reported. The cumulative risk of recurrent parasitaemia was >19-fold higher in the EFV-arm than in the control-arm (Hazard ratio [HR], 19.11 [95% confidence interval {CI}, 10.5-34.5]; P < 0.01). The cumulative risk of recurrent parasitaemia in the NVP-arm was not significantly higher than in the control-arm ([HR], 2.44 [95% {CI}, 0.79-7.6]; P = 0.53). The median (IQR) day 7 plasma concentrations of lumefantrine for the three arms were: 1,125 ng/m (638.8-1913), 300.4 ng/ml (220.8-343.1) and 970 ng/ml (562.1-1729) for the NVP-arm, the EFV-arm and the control-arm, respectively (P < 0.001). In all three arms, the reported adverse events were mostly mild. After 28 days of follow-up, AL was statistically safe and effective in the treatment of uncomplicated malaria in the NVP-arm. The results of this study also provide an indication of the possible impact of EFV on the performance of AL and the likelihood of it affecting uncomplicated falciparum malaria treatment outcome.

We aimed to compare long-term social outcomes in young adults with childhood-onset epilepsy (cases) with neurologically normal sibling controls. Long-term social outcomes were assessed at the 15-year follow-up of the Connecticut Study of Epilepsy, a community-based prospective cohort study of children with newly diagnosed epilepsy. Young adults with childhood-onset epilepsy with complicated (abnormal neurologic exam findings, abnormal brain imaging with lesion referable to epilepsy, intellectual disability (ID; IQ < 60) or informative history of neurologic insults to which the occurrence of epilepsy might be attributed), and uncomplicated epilepsy presentations were compared to healthy sibling controls. Age, gender, and matched-pair adjusted generalized linear models stratified by complicated epilepsy and 5-year seizure-free status estimated adjusted odds ratios (aORs) and 95% confidence intervals [CIs] for each outcome. The 15-year follow-up included 361 individuals with epilepsy (59% of initial cases; N = 291 uncomplicated and N = 70 complicated epilepsy; mean age 22 years [standard deviation, SD 3.5]; mean epilepsy onset 6.2 years [SD 3.9]) and 173 controls. Social outcomes for cases with uncomplicated epilepsy with ≥5 years terminal remission were comparable to controls; cases with uncomplicated epilepsy <5 years seizure-free were more likely to be less productive (school/employment < 20 h/week) (aOR 3.63, 95% CI 1.83-7.20) and not to have a driver's license (aOR 6.25, 95% CI 2.85-13.72). Complicated cases with epilepsy <5 years seizure-free had worse outcomes across multiple domains; including not graduating high school (aOR 24.97, 95% CI 7.49-83.30), being un- or underemployed (<20 h/week) (aOR 11.06, 95% CI 4.44-27.57), being less productively engaged (aOR 15.71, 95% CI 6.88-35.88), and not living independently (aOR 10.24, 95% CI 3.98-26.36). Complicated cases without ID (N = 36) had worse outcomes with respect to productive engagement (aOR 6.02; 95% CI 2.48-14.58) compared to controls. Cases with complicated epilepsy were less likely to be driving compared to controls, irrespective of remission status or ID. In individuals with uncomplicated childhood-onset epilepsy presentations and 5-year terminal remission, young adult social outcomes are comparable to those of sibling controls. Complicated epilepsy, notable for intellectual disability, and seizure remission status are important prognostic indicators for long-term young adult social outcomes in childhood-onset epilepsy.

The burden of maternal ill-health includes not only the levels of maternal mortality and complications during pregnancy and around the time of delivery but also extends to the standard postpartum period of 42 days with consequences of obstetric complications and poor management at delivery. There is a dearth of reliable data on these postpartum maternal morbidities and disabilities in developing countries, and more research is warranted to investigate these and further strengthen the existing safe motherhood programmes to respond to these conditions. This study aims at identifying the consequences of pregnancy and delivery in the postpartum period, their association with acute obstetric complications, the sociodemographic characteristics of women, mode and place of delivery, nutritional status of the mother, and outcomes of birth. From among women who delivered between 2007 and 2008 in the icddr,b service area in Matlab, we prospectively recruited all women identified with complicated births (n=295); a perinatal mortality (n=182); and caesarean-section delivery without any maternal indication (n=147). A random sample of 538 women with uncomplicated births, who delivered at home or in a facility, was taken as the control. All subjects were clinically examined at 6-9 weeks for postpartum morbidities and disabilities. Postpartum women who had suffered obstetric complications during birth and delivered in a hospital were more likely to suffer from hypertension [adjusted odds ratio (AOR)=3.44; 95% confidence interval (CI)=1.14-10.36], haemorrhoids (AOR=1.73; 95% CI=1.11-3.09), and moderate to severe anaemia (AOR=7.11; 95% CI=2.03-4.88) than women with uncomplicated normal deliveries. Yet, women who had complicated births were less likely to have perineal tears (AOR=0.05; 95% CI=0.02-0.14) and genital prolapse (AOR=0.22; 95% CI=0.06-0.76) than those with uncomplicated normal deliveries. Genital infections were more common amongst women experiencing a perinatal death than those with uncomplicated normal births (AOR=1.92; 95% CI=1.18-3.14). Perineal tears were significantly higher (AOR=3.53; 95% CI=2.32-5.37) among those who had delivery at home than those giving birth in a hospital. Any woman may suffer a postpartum morbidity or disability. The increased likelihood of having hypertension, haemorrhoids, or anaemia among women with obstetric complications at birth needs specific intervention. A higher quality of maternal healthcare services generally might alleviate the suffering from perineal tears and prolapse amongst those with a normal uncomplicated delivery.

Conservative management versus endovascular or open surgery in the spectrum of type B aortic dissection.

Type B aortic dissection is a life-threatening acute aortic condition often with acute ischemic signs or symptoms. With initial management focusing on alleviating malperfusion and pain, and avoiding propagation of dissection or rupture both systolic blood and pulse pressure should be reduced initially by an aggressive medical approach. In the setting of persistent signs of complications endovascular strategies have replaced open surgery and led to a fourfold increase in early survival and better long-term outcomes. An electronic health database search was performed on articles published between January 2006 and July 2017. Publications were included in this review if (I) the index aortic pathology was type B aortic (distal) dissection; (II) when medical management, open surgical replacement or thoracic endovascular aortic repair were among those options; (III) when at least one of all basic outcome criteria such as survival, spinal cord ischemia and cerebrovascular accident was reported; (IV) when ≥15 serial patients were included. A total of 62 studies were eligible and analysed. Our manuscript has summarized data collected over 12 years on management specific outcomes in the setting of distal aortic dissection and provides an up-to-date interpretation of the published evidence. For complicated cases, treated acutely, the 30-day or in-hospital mortality was 7.3% when managed by endovascular means, whereas the pooled rate for 30-day or in-hospital mortality was 19.0% when subjected to open repair. For acute uncomplicated type B dissection usually treated with blood pressure lowering medications, the pooled 30-day or in-hospital mortality rate was 2.4%. Survival rates at 5 years averaged at 60% (40% mortality). Freedom from any aortic event ranged from 34.0% to 83.9%, underlining an inherent risk of progression and late complications. For chronic complicated type B dissection, the rates of stroke, paraplegia and operative mortality following endovascular repair ranged from 5% to 13%, 2% to 13% and 2 to 13%, respectively, while 5-year survival rates after open repair ranged from 60% to 90%. In chronic uncomplicated type B dissection almost 90% of patients survive initial hospitalization and were subjected to medical management with a 5-year survival of 50-80%. However, up to 20-55% of medically treated patients develop aneurysmal degeneration after 5 years with an unknown risk of rupture. Currently, the less invasive strategy of endovascular repair (as compared to open surgery) provides improved 30-day or in-hospital survival in the setting of complicated acute type B aortic dissection and may seek broad application. Open surgical aortic reconstruction should be left to experienced aortic centres if endovascular management is not an option.

The Treatment of Plasmodium knowlesi Malaria.

Plasmodium knowlesi occurs across Southeast Asia and is the most common cause of malaria in Malaysia. High parasitaemias can develop rapidly, and the risk of severe disease in adults is at least as high as in falciparum malaria. Prompt initiation of effective treatment is therefore essential. Intravenous artesunate is highly effective in severe knowlesi malaria and in those with moderately high parasitaemia but otherwise uncomplicated disease. Both chloroquine and artemisinin-combination therapy (ACT) are highly effective for uncomplicated knowlesi malaria, with faster parasite clearance times and lower anaemia rates with ACT. Given the difficulties with microscope diagnosis of P. knowlesi, a unified treatment strategy of ACT for all Plasmodium species is recommended in coendemic regions. Copyright © 2016 Elsevier Ltd.

Urinary tract infections (UTIs) are infectious diseases that commonly occur in communities. Although several international guidelines for the management of UTIs have been available, clinical characteristics, etiology and antimicrobial susceptibility patterns may differ from country to country. This work represents an update of the 2011 Korean guideline for UTIs. The current guideline was developed by the update and adaptation method. This clinical practice guideline provides recommendations for the diagnosis and management of UTIs, including asymptomatic bacteriuria, acute uncomplicated cystitis, acute uncomplicated pyelonephritis, complicated pyelonephritis related to urinary tract obstruction, and acute bacterial prostatitis. This guideline targets community-acquired UTIs occurring among adult patients. Healthcare-associated UTIs, catheter-associated UTIs, and infections in immunocompromised patients were not included in this guideline. PMID:29637759

To investigate the incidence and risk factors associated with uncomplicated maternal sepsis and progression to severe sepsis in a large population-based birth cohort. This retrospective cohort study used linked hospital discharge and vital statistics records data for 1,622,474 live births in California during 2005-2007. Demographic and clinical factors were adjusted using multivariable logistic regression with robust standard errors. 1598 mothers developed sepsis; incidence of all sepsis was 10 per 10,000 live births (95% CI = 9.4-10.3). Women had significantly increased adjusted odds (aOR) of developing sepsis if they were older (25-34 years: aOR = 1.29; ≥35 years: aOR = 1.41), had ≤high-school education (aOR = 1.63), public/no-insurance (aOR = 1.22) or a cesarean section (primary: aOR = 1.99; repeat: aOR = 1.25). 791 women progressed to severe sepsis; incidence of severe sepsis was 4.9 per 10,000 live births (95% CI = 4.5-5.2). Women had significantly increased adjusted odds of progressing to severe sepsis if they were Black (aOR = 2.09), Asian (aOR = 1.59), Hispanic (aOR = 1.42), had public/no-insurance (aOR = 1.52), delivered in hospitals with <1,000 births/year (aOR = 1.93), were primiparous (aOR = 2.03), had a multiple birth (aOR = 3.5), diabetes (aOR = 1.47), or chronic hypertension (aOR = 8.51). Preeclampsia and postpartum hemorrhage were also significantly associated with progression to severe sepsis (aOR = 3.72; aOR = 4.18). For every cumulative factor, risk of uncomplicated sepsis increased by 25% (95% CI = 17.4-32.3) and risk of progression to severe sepsis/septic shock increased by 57% (95% CI = 40.8-74.4). The rate of severe sepsis was approximately twice the 1991-2003 national estimate. Risk factors identified are relevant to obstetric practice given their cumulative risk effect and the apparent increase in severe sepsis incidence.

Several studies have demonstrated the safety and short-term success of nonoperative management in children with acute, uncomplicated appendicitis. Nonoperative management spares the patients and their family the upfront cost and discomfort of surgery, but also risks recurrent appendicitis. Using decision-tree software, we evaluated the cost-effectiveness of nonoperative management versus routine laparoscopic appendectomy. Model variables were abstracted from a review of the literature, Healthcare Cost and Utilization Project, and Medicare Physician Fee schedule. Model uncertainty was assessed using both one-way and probabilistic sensitivity analyses. We used a $100,000 per quality adjusted life year (QALY) threshold for cost-effectiveness. Operative management cost $11,119 and yielded 23.56 quality-adjusted life months (QALMs). Nonoperative management cost $2277 less than operative management, but yielded 0.03 fewer QALMs. The incremental cost-to-effectiveness ratio of routine laparoscopic appendectomy was $910,800 per QALY gained. This greatly exceeds the $100,000/QALY threshold and was not cost-effective. One-way sensitivity analysis found that operative management would become cost-effective if the 1-year recurrence rate of acute appendicitis exceeded 39.8%. Probabilistic sensitivity analysis indicated that nonoperative management was cost-effective in 92% of simulations. Based on our model, nonoperative management is more cost-effective than routine laparoscopic appendectomy for children with acute, uncomplicated appendicitis. Cost-Effectiveness Study: Level II.

To determine the differences in hemoglobin (Hb) levels in the first 2 days after birth in uncomplicated monochorionic twins in relation to birth order and mode of delivery. All consecutive uncomplicated monochorionic pregnancies with two live-born twins delivered at our center were included in this retrospective study. We recorded Hb levels at birth and on day 2, and analyzed Hb levels in association with birth order, mode of delivery, and time interval between delivery of twin 1 and 2. A total of 290 monochorionic twin pairs were analyzed, including 171 (59%) twins delivered vaginally and 119 (41%) twins born by cesarean section (CS). In twins delivered vaginally, mean Hb levels at birth and on day 2 were significantly higher in second-born twins compared to first-born twins: 17.8 versus 16.1 g/dL and 18.0 versus 14.8 g/dL, respectively (p < .01). Polycythemia was detected more often in second-born twins (12%, 20/166) compared to first-born twins (1%, 2/166; p < .01). Hb differences within twin pairs delivered by CS were not statistically or clinically significant. We found no association between inter-twin delivery time intervals and Hb differences. Second-born twins after vaginal delivery have higher Hb levels and more often polycythemia than their co-twin, but not when born by CS.

Recent consensus guidelines delineate what appears to be the most successful and cost-effective management of low back pain (LBP), and some recent studies have suggested that better outcomes occur with the least aggressive forms of medical intervention. The purpose of this study was to describe how practitioners manage new-onset, uncomplicated low back workers' compensation (WC) disability cases. A sample of cases was randomly selected from a large insurance carrier's national data source. An effort was made to select only uncomplicated cases, which would be expected to have relatively minimal need for medical intervention. There was an apparent overuse of diagnostic and treatment modalities. Diagnostic imaging was overutilized, not only in terms of the number of studies done (65% had plain films, 22% had magnetic resonance imaging scans) but also in the time frame in which they were performed (38% had plain films on the first clinic visit). Ninety percent received at least one medication, and 38% received more than one prescription for opioid analgesics. Expensive non-steroidal anti-inflammatory drugs were prescribed more often than acetaminophen (61% versus 6%, respectively). Sixty-two percent received physical therapy that often included modalities with as yet unproven efficacy. Overutilization of either diagnostic or treatment procedures increases the likelihood of iatrogenic complications, is not cost-effective, and may adversely impact clinical and occupational outcomes.

Recurrent uncomplicated urinary tract infections in women: a review.

Nosseir, Sandy B; Lind, Lawrence R; Winkler, Harvey A

2012-03-01

Recurrent urinary tract infections most often present with symptoms of irritative voiding. In most cases, they are caused by reinfection with a previously isolated organism. Patients with one or more symptoms of uncomplicated recurrent urinary tract infection should undergo thorough examination and screening for underlying comorbidities that increase susceptibility. When frequent reinfections, empiric treatment relapse, persistent infections, or risk factors for complicated infections are encountered, patients may benefit from urodynamics, cystoscopy, renal ultrasound, intravenous urogram, or voiding cystourethrogram to evaluate for anatomic, functional, or metabolic abnormalities affecting the urinary tract (e.g., stones, stricture, obstruction, vesicoureteral reflux, lesions, detrusor underactivity). These patients may benefit from culture-guided empiric treatment and further evaluation by urology, nephrology, or infectious disease specialists. In patients with a history of uncomplicated urinary tract infections, empiric treatment guided by local antimicrobial resistance may efficiently treat a suspected recurrence. After successful treatment of the acute infection, postcoital prophylaxis, continuous prophylaxis, or self-start empiric treatment may be selected based on frequency of recurrent infections, temporal relation to intercourse, and patient characteristics. Ancillary measures such as probiotics, cranberry products, or local estrogen replacement may also be considered. This article will review the current definition, epidemiology, pathogenesis, diagnosis, work-up, treatment, treatment side effects, and prevention of recurrent urinary tract infections in women. A suggested algorithm for evaluation and treatment based on current literature is provided.

Purpose Transumbilical laparoscopic-assisted appendectomy (TULA) is a single incision technique that uses a combined intra- and extracorporeal method. The aim of this study was to compare surgical outcomes of TULA with conventional 3-port laparoscopic appendectomy (LA). Methods A retrospective review of medical records between 2010 and 2014 identified 303 pediatric patients who underwent LA with uncomplicated acute appendicitis. Of these, 85 patients underwent TULA and 218 patients underwent conventional LA. Demographic data, clinical characteristics, perioperative outcomes and postoperative complications were compared between the 2 groups. Results The mean operation time in the TULA group was 30.39 minutes, which was significantly shorter than that of the LA group (47.83 minutes) (P < 0.001). The first day of oral intake after surgery was earlier (1.05 days vs. 1.32 days; P < 0.001) and the length of hospital stay was also shorter (2.54 days vs. 3.22 days; P < 0.001) for the TULA group than the LA group. Furthermore, the postoperative complication rate was lower in the TULA group (1 of 85, 1.25%) compared to the LA group (19 of 218, 8.7%) (P = 0.018). Conclusion In conclusion, TULA procedure is recommended for uncomplicated appendicitis in children due to its simplicity and better postoperative outcomes. PMID:27478813

Although few reports address the use of three-phase bone scanning (TPBS) and {sup 111}In-labeled white blood cell (In-WBC) scintigraphy in hip arthroplasty utilizing a porous coated prosthesis, the literature suggests that scintigraphic patterns in the uncomplicated patient may differ from that seen in the cemented prosthesis. In an attempt to determine the scintigraphic natural history, 25 uncomplicated porous coated hip arthroplasties in 21 patients were prospectively studied with serial TPBS and In-WBC at approximately 7 days, and at 3, 6, 12, 18, and 24 mo postoperatively. This report deals with findings related to the prosthetic tip. Only one of 136more » flow studies were abnormal and only two of 136 blood-pool images demonstrated focally increased activity. All 25 prostheses (120 of 143 scans) demonstrated increased uptake on the bone phase images. The area about the tip was divided into three segments; increased uptake at 24 mo was noted in the medial, distal, and lateral segments in 16%, 72%, and 56% of prostheses, respectively. Twenty of 25 prostheses (82 of 142 scans) showed uptake on In-WBC scintigraphy, being noted in 48% of prostheses at 24 mo. We conclude that scintigraphic patterns in the uncomplicated patient with a porous coated prosthesis appear to differ from patterns described in cemented prostheses.« less

AIM: While hepatocellular adenomas (HAs) have often been studied as a unique entity, we aimed to better define current management of the various forms of HAs. METHODS: Twenty-five consecutive patients operated for solitary-uncomplicated (9), multiple (6), and ruptured (10) HAs were reviewed according to management strategies and outcomes. RESULTS: All solitary-uncomplicated HAs (ranged 2.2-14 cm in size) were removed. Out of 25 HAs, 2 (8%) included foci of carcinoma. In the multiple HA group, previously undiagnosed tumors were identified during surgery in 5/6 cases. In three cases with multiple spread HA, several lesions had to be left unresected. They remained unmodified after 4-, 6-, and 6-year radiological follow-up. Patients with ruptured HA (ranged 1.7-10 cm in size) were initially managed with hemodynamic support and angiography, allowing the embolization of actively bleeding tumors in two patients. All ruptured tumors were subsequently removed 5.5 d (range 4-70 d) after admission. CONCLUSION: Tumors suspected of HA, regardless of the size, should be resected, because of high chances of rupture causing bleeding, and/or containing malignant foci. Although it is desirable to remove all lesions of multiple HA, this may not be possible in some patients, for whom long-term radiological follow-up is advised. Ruptured HA can be managed by hemodynamic support and angiography, allowing scheduled surgery. PMID:16237767

Enrolled in this study were 39 diabetic adolescents, characterized by optimal Early Treatment Diabetic Retinopathy Study criteria for visual acuity, transparent dioptric means and angiographically normal retinas. Color vision was examined with Standard Pseudoisochromatic Plates (Part 2, SPP2), Roth 28-Hue Test (R28), Farnsworth-Munsell 100-Hue Tests (FM100), and Lanthony 15-Hue Desaturated Test (L15). Color confusion score (CCS) and desaturation angle (DSAT) were measured on L15 only. Thirty-nine normal subjects served as a control group. Poor metabolic control was an exclusion criteria. CCS was significantly higher in the patients than in the controls (37.8 +/- 11.1 vs 0 +/- P < .001) and normal scores were found in only 4 diabetic patients. DSAT values were spread, not showing a well-defined axis of the defect. The results of FM100 were clinically reliable but affected by a longer execution time. R28 and SPP2 demonstrated a low sensitivity, as all patients scored normally with both tests. Impaired color vision is a common observation even in patients with uncomplicated juvenile diabetes. Our results indicate that L15 is the most suitable test for screening of early color vision abnormalities in these subjects.

Clinical Presentations and Epidemiology of Urinary Tract Infections.

Urinary tract infection (UTI) is one of the most common bacterial infections, and the incidence in women is much higher than in men. The diagnosis of a UTI can be made based on a combination of symptoms and a positive urine analysis or culture. Most UTIs are uncomplicated UTIs, defined as cystitis in a woman who is not pregnant, is not immunocompromised, has no anatomical and functional abnormalities of the urogenital tract, and does not exhibit signs of tissue invasion and systemic infection. All UTIs that are not uncomplicated are considered to be complicated UTIs. Differentiation between uncomplicated and complicated UTIs has implications for therapy because the risks of complications or treatment failure are increased for patients with a complicated UTI. Asymptomatic bacteriuria (ASB) is defined as the presence of a positive urine culture collected from a patient without symptoms of a UTI. Concerning the complicated UTI, it is possible to make a differentiation between UTI with systemic symptoms (febrile UTI) and UTI in a host, which carries an increased risk to develop complications of this UTI. Febrile UTIs are urosepsis, pyelonephritis, and prostatitis. A complicated host is defined as one that has an increased risk for complications, to which the following groups belong: men, pregnant women, immunocompromised patients, or those who have an anatomical or functional abnormality of the urogenital tract (e.g., spinal cord-injury patients, renal stones, urinary catheter).

Background Antipyretic drugs are widely used in children with fever, though there is a controversy about the benefit of reducing fever in children with malaria. In order to assess the effect of ibuprofen on fever compared to placebo in children with uncomplicated Plasmodium falciparum malaria in Gabon, a randomized double blind placebo controlled trial, was designed. Methods Fifty children between two and seven years of age with uncomplicated malaria were included in the study. For the treatment of fever, all patients "received" mechanical treatment when the temperature rose above 37.5°C. In addition to the mechanical treatment, continuous fanning and cooling blanket, patients were assigned randomly to receive ibuprofen (7 mg/kg body weight, every eight hours) or placebo. Results The fever clearance time using a fever threshold of 37.5°C was similar in children receiving ibuprofen compared to those receiving placebo. The difference was also not statistically significant using a fever threshold of 37.8°C or 38.0°C. However, the fever time and the area under the fever curve were significantly smaller in the ibuprofen group compared to the placebo group. Conclusion Ibuprofen is effective in reducing the time with fever. The effect on fever clearance is less obvious and depends on definition of the fever threshold.

Comparative, in vivo, human, prospective, single blind, clinical and microbiological diagnoses based and randomised study of the treatment of uncomplicated bacterial vaginosis with two forms of combined (metronidazole + nystatin + sulfadimidin) vaginal suppositories (laminated and mixed containing the same ingredients) and the standard preparations available in the Hungarian market (Dalacin vaginal cream and Klion vaginal suppository). The examinations involved 60 volunteers and were performed in the Gynecological Outpatient Clinic of the Council of Erd, the microbiological samples were examined at Saint Rókus Hospital in Budapest. The combined treatment was better tolerated and resulted in normal vaginal pH significantly more often at the same rate of recovery. The combined treatment is simultaneously effective in cases of the most prevalent coinfections too.

Non-radicular neck pain arising from local musculoskeletal structures, known as mechanical neck pain or somatic dysfunction, is highly prevalent in the fighter jet aviator population. The management of this problem includes both therapeutic and aeromedical decisions. In addition to non-steroidal anti-inflammatory medications, waiver guides recommend therapeutic exercise and manipulative therapy as treatments for somatic spine pain in aviators, and such treatments are employed in many military locations. However, there are currently no published studies that describe the use of manipulative therapy for fighter jet aviators. We report the case of an F/A-18 instructor pilot who experienced long-term relief of uncomplicated mechanical neck pain following interdisciplinary management that included manipulation and a home exercise program. Diagnostic considerations, conservative treatment options, and aeromedical concerns are discussed. PMID:20520753

The revival of old antibiotics for treatment of uncomplicated urinary tract infections in the era of antibiotic stewardship.

In the era of increasing antibiotic resistance worldwide, this review highlights the advantages of revival of old antibiotics for treatment of uncomplicated urinary tract infections (uUTIs). Recent studies have shown that these four oral old antibiotics, fosfomycin trometamol, nitrofurantoin, nitroxoline and pivmecillinam, show no increasing antibiotic resistance against uropathogens causing uUTI, are still effective for the treatment of uUTI and exhibit only minimal or no collateral damage as compared with fluoroquinolones or third-generation cephalosporines. According to the principles of antibiotic stewardship, the prudent use of antibiotics is needed. Therefore, recent international and national guidelines already favour these old oral antibiotics as first-choice treatment of uUTI. Unfortunately, implementation of these guidelines is still suboptimal.

A short cut review was carried out to establish the administration of an alpha-1 receptor antagonist or a calcium channel blocker would facilitate the most rapid and successful expulsion of a stone from a patient with uncomplicated renal colic. 597 articles were found using the reported search, of which five trials were selected as providing the best evidence to answer this question. The authors, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. It is concluded that in a patient with an uncomplicated ureteric calculus tamsulosin is more effective than nifedipine in promoting speedy and successful expulsion of the stone.

Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. There is lack of uniformity in the treatment of CSDH amongst surgeons in terms of various treatment strategies. Clinical presentation may vary from no symptoms to unconsciousness. CSDH is usually diagnosed by contrast-enhanced computed tomography scan. Magnetic resonance imaging (MRI) scan is more sensitive in the diagnosis of bilateral isodense CSDH, multiple loculations, intrahematoma membranes, fresh bleeding, hemolysis, and the size of capsule. Contrast-enhanced CT or MRI could detect associated primary or metastatic dural diseases. Although definite history of trauma could be obtained in a majority of cases, some cases may be secondary to coagulation defect, intracranial hypotension, use of anticoagulants and antiplatelet drugs, etc., Recurrent bleeding, increased exudates from outer membrane, and cerebrospinal fluid entrapment have been implicated in the enlargement of CSDH. Burr-hole evacuation is the treatment of choice for an uncomplicated CSDH. Most of the recent trials favor the use of drain to reduce recurrence rate. Craniotomy and twist drill craniostomy also play a role in the management. Dural biopsy should be taken, especially in recurrence and thick outer membrane. Nonsurgical management is reserved for asymptomatic or high operative risk patients. The steroids and angiotensin converting enzyme inhibitors may also play a role in the management. Single management strategy is not appropriate for all the cases of CSDH. Better understanding of the nature of the pathology, rational selection of an ideal treatment strategy for an individual patient, and identification of the merits and limitations of different surgical techniques could help in improving the prognosis.

Chronic histiocytic intervillositis (CHI) of the placenta although rare, has a high recurrence rate, is associated with serious adverse pregnancy outcomes and has no available treatment. This study aims to determine clinical, biochemical and radiological factors associated with CHI, to guide management of subsequent pregnancies. This retrospective observational study included consecutive cases with a histopathologic diagnosis of CHI after 18 weeks of gestation, between 2001 and 2014, and no controls. Clinical (maternal, fetal and delivery outcomes), biochemical (first- and second-trimester biomarkers for fetal aneuploidy and serum alkaline phosphatase) and radiological (second- and third-trimester fetal, placental and Doppler ultrasound) factors associated with a histopathological diagnosis of CHI were identified and results presented as percentages. Outcomes of subsequent pregnancies were described. Of 231 identified cases of 'intervillositis', 33 were confirmed to have CHI, of which only 4/33 (12.1%) had prior uncomplicated term deliveries. During pregnancy, 10/18 (55.5%) had abnormal first-trimester screening, 4/16 (25%) had abnormal second-trimester screening, 6/19 (31.6%) had at least one elevated alkaline phosphatase level, and 15/20 (75%) had at least one abnormal feature on mid-trimester placental ultrasound. In subsequent pregnancies that were closely followed with a combination of biochemical and radiologic tests, there were no cases of fetal loss, and lower incidence of fetal growth restriction and preterm birth. No clinical, biochemical or radiological finding is consistently associated with CHI and adverse outcomes thereof. Whether the incorporation of these tests in individualized care-plans could improve outcomes in subsequent pregnancies needs to be studied further. Copyright © 2018 Elsevier Ltd.

Background Artemisinin combination therapies (ACTs) are currently the preferred option for treating uncomplicated malaria. Dihydroartemisinin-piperaquine (DHA-PQP) is a promising fixed-dose ACT with limited information on its safety and efficacy in African children. Methodology/Principal Findings The non-inferiority of DHA-PQP versus artemether-lumefantrine (AL) in children 6–59 months old with uncomplicated P. falciparum malaria was tested in five African countries (Burkina Faso, Kenya, Mozambique, Uganda and Zambia). Patients were randomised (2∶1) to receive either DHA-PQP or AL. Non-inferiority was assessed using a margin of −5% for the lower limit of the one-sided 97.5% confidence interval on the treatment difference (DHA-PQP vs. AL) of the day 28 polymerase chain reaction (PCR) corrected cure rate. Efficacy analysis was performed in several populations, and two of them are presented here: intention-to-treat (ITT) and enlarged per-protocol (ePP). 1553 children were randomised, 1039 receiving DHA-PQP and 514 AL. The PCR-corrected day 28 cure rate was 90.4% (ITT) and 94.7% (ePP) in the DHA-PQP group, and 90.0% (ITT) and 95.3% (ePP) in the AL group. The lower limits of the one-sided 97.5% CI of the difference between the two treatments were −2.80% and −2.96%, in the ITT and ePP populations, respectively. In the ITT population, the Kaplan-Meier estimate of the proportion of new infections up to Day 42 was 13.55% (95% CI: 11.35%–15.76%) for DHA-PQP vs 24.00% (95% CI: 20.11%–27.88%) for AL (p<0.0001). Conclusions/Significance DHA-PQP is as efficacious as AL in treating uncomplicated malaria in African children from different endemicity settings, and shows a comparable safety profile. The occurrence of new infections within the 42-day follow up was significantly lower in the DHA-PQP group, indicating a longer post-treatment prophylactic effect.

Artemisinin combination therapy (ACT) has been the first-line treatment for uncomplicated malaria in Cameroon since 2004 and Nigeria since 2005, though many febrile patients receive less effective antimalarials. Patients often rely on providers to select treatment, and interventions are needed to improve providers' practice and encourage them to adhere to clinical guidelines. Providers' adherence to malaria treatment guidelines was examined using data collected in Cameroon and Nigeria at public and mission facilities, pharmacies and drug stores. Providers' choice of antimalarial was investigated separately for each country. Multilevel logistic regression was used to determine whether providers were more likely to choose ACT if they knew it was the first-line antimalarial. Multiple imputation was used to impute missing data that arose when linking exit survey responses to details of the provider responsible for selecting treatment. There was a gap between providers' knowledge and their practice in both countries, as providers' decision to supply ACT was not significantly associated with knowledge of the first-line antimalarial. Providers were, however, more likely to supply ACT if it was the type of antimalarial they prefer. Other factors were country-specific, and indicated providers can be influenced by what they perceived their patients prefer or could afford, as well as information about their symptoms, previous treatment, the type of outlet and availability of ACT. Public health interventions to improve the treatment of uncomplicated malaria should strive to change what providers prefer, rather than focus on what they know. Interventions to improve adherence to malaria treatment guidelines should emphasize that ACT is the recommended antimalarial, and it should be used for all patients with uncomplicated malaria. Interventions should also be tailored to the local setting, as there were differences between the two countries in providers' choice of antimalarial, and who or what influenced their practice.

There are no well-established indications for the surgical management of acute necrotizing pneumonitis in children. This study presents our experience regarding this challenging topic. Between 2002 and 2009, 56 necrotizing pneumonitis patients with empyema were treated surgically. The outcomes were analyzed retrospectively. Computed tomography findings of massive lung necrosis or large cavities involving more than 50% of the involved lobe were deemed to be complicated necrotizing pneumonitis. Patients without the above indications were considered uncomplicated. Thirty-one cases were uncomplicated and 25 were complicated. Operative procedures included 38 decortications (31 uncomplicated and seven complicated), 14 wedge resections, and four lobectomies (complicated only). Preoperatively, patients with complicated necrotizing pneumonia had a higher incidence of pneumothorax (32% vs. 14.3%; p = 0.001), endotracheal intubation (44% vs. 9.7%; p = 0.008), and hemolytic uremic syndrome (20% vs. 3.2%; p = 0.01). These patients also had higher incidences of intraoperative transfusion (68% vs. 9.7%; p = 0.03), major postoperative complications (16% vs. 0%; p = 0.02), reoperations (16% vs. 0%; p = 0.02), and longer postoperative stay (19.8 ± 24.2 days vs. 11.2 ± 5.8 days; p = 0.03). Four complicated patients, who initially had decortications and limited resections, underwent reoperations. Compared with uncomplicated patients, those who underwent decortications and wedge resection required longer postoperative stays (23.6 ± 9.9 days, p < 0.01 and 21.1 ± 30.7 days, p = 0.04, respectively), whereas patients who had lobectomy had a similar duration of recovery (9.0 ± 2.1 days, p = 0.23). All patients improved significantly at follow-up. Children with complicated necrotizing pneumonitis have more preoperative morbidities, more major postoperative complications, and require longer postoperative stays. Aggressive surgical treatment results in significant clinical improvement. Lobectomy in patients with complicated necrotizing pneumonitis may shorten the postoperative course and avoid subsequent surgery. Copyright © 2016. Published by Elsevier B.V.

Indicators of complicated mild TBI predict MMPI-2 scores after 23 years.

Research suggests that post-concussive syndrome may become persistent after mild traumatic brain injury (mTBI). The aim of this study was to investigate determinants of subjective complaints, characteristic for post-concussive syndrome, 23 years after mTBI. The study was a follow-up after a prospective head injury study at a general hospital in Norway. Ninety-seven patients were assessed with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) 23 years after sustaining primarily mTBI. A good overall outcome was found with scores close to the normative mean, average length of education and normal employment rate. However, the patients that sustained complicated mTBI showed somewhat more pathological scores, well-matched with mild post-concussive syndrome. The most important predictors of poor outcome were a combination of post-traumatic amnesia >30 minutes and EEG pathology within 24 hours after TBI. No influence of pre- and post-injury risk factors on current MMPI-2 profiles was found. The results are in line with previous research findings and support the notion of potentially differential impact of uncomplicated vs. complicated mTBI. The findings suggest that complicated mTBI may cause subtle chronic symptoms typical of post-concussive syndrome.

Sporotrichosis: An Overview and Therapeutic Options

PubMed Central

Mahajan, Vikram K.

2014-01-01

Sporotrichosis is a chronic granulomatous mycotic infection caused by Sporothrix schenckii, a common saprophyte of soil, decaying wood, hay, and sphagnum moss, that is endemic in tropical/subtropical areas. The recent phylogenetic studies have delineated the geographic distribution of multiple distinct Sporothrix species causing sporotrichosis. It characteristically involves the skin and subcutaneous tissue following traumatic inoculation of the pathogen. After a variable incubation period, progressively enlarging papulo-nodule at the inoculation site develops that may ulcerate (fixed cutaneous sporotrichosis) or multiple nodules appear proximally along lymphatics (lymphocutaneous sporotrichosis). Osteoarticular sporotrichosis or primary pulmonary sporotrichosis are rare and occur from direct inoculation or inhalation of conidia, respectively. Disseminated cutaneous sporotrichosis or involvement of multiple visceral organs, particularly the central nervous system, occurs most commonly in persons with immunosuppression. Saturated solution of potassium iodide remains a first line treatment choice for uncomplicated cutaneous sporotrichosis in resource poor countries but itraconazole is currently used/recommended for the treatment of all forms of sporotrichosis. Terbinafine has been observed to be effective in the treatment of cutaneous sporotrichosis. Amphotericin B is used initially for the treatment of severe, systemic disease, during pregnancy and in immunosuppressed patients until recovery, then followed by itraconazole for the rest of the therapy.

Ehrhardt, Stephan; Meyer, Christian G

2009-01-01

The World Health Organization strongly recommends artemisinin-based combination therapy (ACT) regimens for the treatment of uncomplicated Plasmodium falciparum malaria cases in endemic areas. Among the combinations of compounds that are available at present, excellent results have been obtained for the artemisinin derivative artemether, in a combination galenic preparation with lumefantrine (artemether–lumefantrine, AL). Here, the pharmacological properties and the therapeutic options of both substances are briefly reviewed and a cursory overview is given on recent trials that have compared the therapeutic effects of AL in the standard 6-dose regimen with other antimalarials and combinations. In order to ensure the most achievable and reliable adherence and compliance of children in the treatment of malaria, a dispersible formulation of AL is now attainable. Recent reports on the emergence of resistance to ACT regimens in Asia, however, are alarming. PMID:19851528

OBJECTIVE Toll-like receptors (TLRs) are integral parts of the innate immune system and have been implicated in complications of pregnancy. The longitudinal expression of TLRs on dendritic cells in the maternal circulation during uncomplicated pregnancies is unknown. The objective of this study was to prospectively evaluate TLRs 1-9 as expressed on dendritic cells in the maternal circulation at defined intervals throughout pregnancy and postpartum. STUDY DESIGN This was a prospective cohort of 30 pregnant women with uncomplicated pregnancies and 30 nonpregnant controls. TLRs and cytokine expression was measured in unstimulated dendritic cells at 4 defined intervals during pregnancy and postpartum. Basal expression of TLRs and cytokines was measured by multicolor flow cytometry. The percent-positive dendritic cells for each TLRs were compared with both nonpregnant and postpartum levels with multivariate linear regression. RESULTS TLRs 1, 7, and 9 were elevated compared with nonpregnant controls with persistent elevation of TLR 1 and interleukin-12 (IL-12) into the postpartum period. Concordantly, levels of IL-6, IL-12, interferon alpha, and tumor necrosis factor alpha increased during pregnancy and returned to levels similar to nonpregnant controls during the postpartum period. The elevated levels of TLR 1 and IL-12 were persistent postpartum, challenging notions that immunologic changes during pregnancy resolve after the prototypical postpartum period. CONCLUSION Normal pregnancy is associated with time-dependent changes in TLR expression compared with nonpregnant controls; these findings may help elucidate immunologic dysfunction in complicated pregnancies.

Evidence-based information on the resumption of daily activities following uncomplicated abdominal surgery is scarce and not yet standardized in medical guidelines. As a consequence, convalescence recommendations are generally not provided after surgery, leading to patients' insecurity, needlessly delayed recovery and prolonged sick leave. The aim of this study was to generate consensus-based multidisciplinary convalescence recommendations, including advice on return to work, applicable for both patients and physicians. Using a modified Delphi method among a multidisciplinary panel of 13 experts consisting of surgeons, occupational physicians and general practitioners, detailed recommendations were developed for graded resumption of 34 activities after uncomplicated laparoscopic cholecystectomy, laparoscopic and open appendectomy, laparoscopic and open colectomy and laparoscopic and open inguinal hernia repair. A sample of occupational physicians, general practitioners and surgeons assessed the recommendations on feasibility in daily practice. The response of this group of care providers was discussed with the experts in the final Delphi questionnaire round. Out of initially 56 activities, the expert panel selected 34 relevant activities for which convalescence recommendations were developed. After four Delphi rounds, consensus was reached for all of the 34 activities for all the surgical procedures. A sample of occupational physicians, general practitioners and surgeons regarded the recommendations as feasible in daily practice. Multidisciplinary convalescence recommendations regarding uncomplicated laparoscopic cholecystectomy, appendectomy (laparoscopic, open), colectomy (laparoscopic, open) and inguinal hernia repair (laparoscopic, open) were developed by a modified Delphi procedure. Further research is required to evaluate whether these recommendations are realistic and effective in daily practice.

Background Knowledge of existing prescription patterns in the treatment of newly-diagnosed hypertension can provide useful information for improving clinical practice in this field. The aims of this study are to determine the prescription patterns and time trends for antihypertensive medication in newly-diagnosed cases of uncomplicated hypertension in Taiwan and to compare these with current clinical guidelines. Methods A total of 6,536 newly-diagnosed patients with uncomplicated hypertension, aged ≥30 years, were identified from the representative 200,000-person sample in the computerized reimbursement database of the National Health Insurance in Taiwan. These patients were followed from 1998 to 2004 with all diagnoses, prescription data and medication charges being retrieved for subsequent analysis. Results Prescription patterns varied by age, gender and clinical facilities, with mono-therapies being found to be dominant in the first year, albeit declining over time. Calcium channel blockers and beta-blockers were the most frequently prescribed antihypertensive drugs, either alone or in combinations. Although least expensive, the prescription rates of diuretics were low, at 8.3% for mono-therapies and 19.9% overall. The prescription rate for angiotensin receptor blockers (ARBs) was elevated considerably over time. After controlling for other related factors by multiple logistic regression analysis, ARBs were found to be prescribed mainly by medical centers or regional hospitals. Conclusion These findings indicate the existence of a gap between current clinical practice and the desired goal of cost-effectiveness in antihypertensive treatment in Taiwan, which should be corrected.

To investigate the effectiveness and safety of a symbiotic mixture in preventing recurrence of constipation-related abdominal pain in patients with uncomplicated diverticular disease of the colon. Forty-six consecutive patients (10 men, 36 women, mean age 62.5 years, range 49 to 77 years), previously affected by symptomatic uncomplicated diverticular disease of the colon, were enrolled in a 6-month follow-up study in a prospective, randomized, open-label study. The following symptoms were assessed at entry and through follow-up by using a quantitative scale: constipation, diarrhoea and abdominal pain. After recruitment, the patients were assigned to the following treatment: SCM-III symbiotic mixture, 10 ml three times a day. The colonization of ingested Lactobacillus acidophilus 145 and Bifidobacterium spp. 420 was assessed by species-specific PCR. Forty-five patients completed the study (97%). Thirty-one patients (68%) were still symptom free after the 6th month of treatment. Treatment with SCM-III was regarded as "effective" or "very effective" in more than 78% of the patients altogether (p<0.01 vs baseline values). The microbiological study showed that, as compared to baseline values, SCM-III enabled a significant increase of the lactobacilli and bifidobacteria counting and a trend decrease of clostridia. Genomic analysis confirmed the survivability of the ingested strain as long as treatment was given. The present symbiotic mixture seems to be effective in preventing recurrence of symptomatic uncomplicated diverticular disease of the colon, especially in those patients with constipation-predominant features.

Plasmodium falciparum merozoite antigens elicit antibody responses in malaria-endemic populations, some of which are clinically protective, which is one of the reasons why merozoite antigens are the focus of malaria vaccine development efforts. Polymorphisms in several merozoite antigen-encoding genes are thought to arise as a result of selection by the human immune system. The allele frequency distribution of 15 merozoite antigens over a two-year period, 2007 and 2008, was examined in parasites obtained from children with uncomplicated malaria. In the same population, allele frequency changes pre- and post-anti-malarial treatment were also examined. Any gene which showed a significant shift in allele frequencies was also assessed longitudinally in asymptomatic and complicated malaria infections. Fluctuating allele frequencies were identified in codons 147 and 148 of reticulocyte-binding homologue (Rh) 5, with a shift from HD to YH haplotypes over the two-year period in uncomplicated malaria infections. However, in both the asymptomatic and complicated malaria infections YH was the dominant and stable haplotype over the two-year and ten-year periods, respectively. A logistic regression analysis of all three malaria infection populations between 2007 and 2009 revealed, that the chance of being infected with the HD haplotype decreased with time from 2007 to 2009 and increased in the uncomplicated and asymptomatic infections. Rh5 codons 147 and 148 showed heterogeneity at both an individual and population level and may be under some degree of immune selection.

Hospital practices supportive of breastfeeding can improve breastfeeding rates. There are limited data available on how improved hospital practices are associated with hospital costs. We describe the association between the number of breastfeeding supportive practices a hospital has in place and the cost of an uncomplicated birth. Data from hospitals in 20 states that participated in the 2007 Maternity Practices in Infant Nutrition and Care (mPINC) survey and Healthcare Cost and Utilization Project's (HCUP) State Inpatient Databases (SID) were merged to calculate the average median hospital cost of uncomplicated vaginal and cesarean section births by number of ideal practices from the Ten Steps to Successful Breastfeeding. Linear regression analyses were conducted to estimate change in birth cost for each additional ideal practice in place. Sixty-one percent of hospitals had ideal practice on 3-5 of the 10 steps, whereas 29 percent of hospitals had ideal practice on 6-8. Adjusted analyses of uncomplicated births revealed a higher but nonsignificant increase in any of the birth categories (all births, $19; vaginal, $15; cesarean section, $39) with each additional breastfeeding supportive maternity care practice in place. Our results revealed that the number of breastfeeding supportive practices a hospital has in place is not significantly associated with higher birth costs. Concern for higher birth costs should not be a barrier for improving maternity care practices that support women who choose to breastfeed. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.

The expanding role of fluoroquinolones.

PubMed

Schaeffer, Anthony J

2003-02-01

There has been a growing rate of resistance among common urinary tract pathogens, such as Escherichia coli, to traditional antimicrobial therapies including the "gold standard" trimethoprim-sulfamethoxazole (TMP-SMX). Consequently, fluoroquinolone antimicrobial agents have taken on an expanding management role for UTIs. In fact, the recent Infectious Diseases Society of America clinical management guidelines for UTI recommend fluoroquinolones as first-line therapy for uncomplicated UTI in areas where resistance is likely to be of concern. Fluoroquinolones have demonstrated high bacteriologic and clinical cure rates, as well as low rates of resistance, among most common uropathogens. There are currently 7 fluoroquinolones with indications for UTI in the United States. However, only 3 are commonly used: levofloxacin, ciprofloxacin, and, to a lesser extent, gatifloxacin. Many of the fluoroquinolone agents have once-daily dosing regimens, enhancing patient adherence. In addition, levofloxacin and gatifloxacin have same-dose bioequivalency between their intravenous and oral formulations, allowing for "switch" or step-down therapy from parenteral to oral formulations of the same agent at the same dose. Fluoroquinolones are indicated for the management of acute uncomplicated UTIs, as well as complicated and severe UTI and pyelonephritis, in adults. They are the first-line treatment of acute uncomplicated cystitis in patients who cannot tolerate sulfonamides or TMP, who live in geographic areas with known resistance >10% to 20% to TMP-SMX, or who have risk factors for such resistance. Fluoroquinolone properties include a broad spectrum of coverage, low rates of resistance, and good safety profiles.

To investigate long-term intraocular pressure trends after uncomplicated pars plana vitrectomy for idiopathic epiretinal membrane. Three hundred and sixty-eight eyes of 368 consecutive patients were enrolled. Changes in intraocular pressure 1, 3, 6, and 12 months after surgery and during the final follow-up visit were evaluated in vitrectomized eyes and nonvitrectomized fellow eyes. The median follow-up period was 36 months (range 12-92 months). Longitudinal data analysis evidenced a 2.5-mmHg (2.2 mmHg; 2.7 mmHg, 95% confidence interval) statistically significant difference in intraocular pressure 30 days after surgery between treated and fellow untreated eyes, gradually recovering to a not significant 0.2-mmHg (-0.1 mmHg; 0.4 mmHg, 95% confidence interval) difference within 26 months. The incidence of late-onset ocular hypertension was 5.7% (21 over 347, 2%; 12%, 95% confidence interval) without difference between the treated eyes and the group control. No significant difference in the incidence of late-onset ocular hypertension and sex, lens status, or gauge of vitrectomy instruments was detected. Only patient's age was significantly higher (mean difference 4.2 years; 0.1-8.0 years, Monte Carlo, 95% confidence interval) in those who developed late-onset ocular hypertension in the vitrectomized eye. Uncomplicated pars plana vitrectomy for idiopathic epiretinal membrane seems not to increase the risk of late-onset ocular hypertension or open-angle glaucoma development.

The purpose of this study was to characterize epidemiologic trends and cost implications of hospital readmission after treatment of pediatric appendicitis. We conducted a 5-year retrospective cohort analysis of 30-day readmission rates for 52,054 patients admitted with appendicitis at 38 children's hospitals participating in the Pediatric Health Information System database. Patients were categorized as "uncomplicated" (postoperative length of stay [LOS] ≤ 2 days) or "complicated" (LOS ≥ 3 days and ≥ 4 consecutive days of antibiotics) and analyzed for demographic data, treatment received during the index admission, readmission rates, and excess LOS and hospital-related costs attributable to readmission encounters. The aggregate 30-day readmission rate was 8.7%, and this varied significantly by disease severity and management approach (uncomplicated appendectomy, 5.6%; complicated appendectomy, 12.8%; drainage, 22.6%; antibiotics only, 24.6%; P < .0001). The median hospital cost per case attributable to readmission was $3401 (reflecting a 44% relative increase in cumulative treatment-related cost), and this varied significantly by disease severity and management approach (uncomplicated appendectomy, $1946 [31% relative increase]; complicated appendectomy, $6524 [53% increase]; drainage, $6827 [48% increase]; antibiotics only, $5835 [58% increase]; P < .0001). In freestanding children's hospitals, readmission after treatment of pediatric appendicitis is a relatively common and costly occurrence. Collaborative efforts are needed to characterize patient, treatment, and hospital-related risk factors as a basis for developing preventative strategies. Copyright © 2012 Elsevier Inc.

There may be some differences in the in vivo behavior of 68Ga-chloride and 68Ga-citrate leading to different accumulation profiles. This study compared 68Ga-citrate and 68Ga-chloride PET/CT imaging under standardized experimental models. Methods. Diffuse Staphylococcus aureus tibial osteomyelitis and uncomplicated bone healing rat models were used (n = 32). Two weeks after surgery, PET/CT imaging was performed on consecutive days using 68Ga-citrate or 68Ga-chloride, and tissue accumulation was confirmed by ex vivo analysis. In addition, peripheral quantitative computed tomography and conventional radiography were performed. Osteomyelitis was verified by microbiological analysis and specimens were also processed for histomorphometry. Results. In PET/CT imaging, the SUVmax of 68Ga-chloride and 68Ga-citrate in the osteomyelitic tibias (3.6 ± 1.4 and 4.7 ± 1.5, resp.) were significantly higher (P = 0.0019 and P = 0.0020, resp.) than in the uncomplicated bone healing (2.7 ± 0.44 and 2.5 ± 0.49, resp.). In osteomyelitic tibias, the SUVmax of 68Ga-citrate was significantly higher than the uptake of 68Ga-chloride (P = 0.0017). In animals with uncomplicated bone healing, no difference in the SUVmax of 68Ga-chloride or 68Ga-citrate was seen in the operated tibias. Conclusions. This study further corroborates the use of 68Ga-citrate for PET imaging of osteomyelitis. PMID:29681785

Fosfomycin trometamol: a review of its use as a single-dose oral treatment for patients with acute lower urinary tract infections and pregnant women with asymptomatic bacteriuria.

2013-11-01

Fosfomycin trometamol (fosfomycin tromethamine) [Monuril(®), Monurol(®), Monural(®)] is approved in numerous countries worldwide, mainly for the treatment of uncomplicated urinary tract infections (UTIs). Fosfomycin has good in vitro activity against common uropathogens, such as Escherichia coli (including extended-spectrum β-lactamase-producing E. coli), Proteus mirabilis, Klebsiella pneumoniae and Staphylococcus saprophyticus, and the susceptibility of uropathogens to fosfomycin has remained relatively stable over time. A single oral dose of fosfomycin trometamol 3 g (the approved dosage) achieves high concentrations in urine. Results of recent randomized trials indicate that single-dose fosfomycin trometamol had similar clinical and/or bacteriological efficacy to 3- to 7-day regimens of ciprofloxacin, norfloxacin, cotrimoxazole or nitrofurantoin in women with uncomplicated lower UTIs. In addition, single-dose fosfomycin trometamol had similar bacteriological efficacy to a 5-day course of cefuroxime axetil or a 7-day course of amoxicillin/clavulanic acid in pregnant women with asymptomatic bacteriuria, and similar clinical and/or bacteriological efficacy to a 5-day course of cefuroxime axetil or amoxicillin/clavulanic acid or a 3-day course of ceftibuten in pregnant women with a lower UTI. Single-dose fosfomycin trometamol was generally well tolerated, with gastrointestinal adverse events (e.g. diarrhoea, nausea) reported most commonly. In conclusion, single-dose fosfomycin trometamol is an important option for the first-line empirical treatment of uncomplicated lower UTIs.

We assessed Plasmodium falciparum mdr1 (Pfmdr1) gene polymorphisms and copy numbers as well as P. falciparum Ca2+ ATPase (PfATPase6) gene polymorphisms in 90 Nigerian children presenting with uncomplicated falciparum malaria and enrolled in a study of the efficacy of artemether-lumefantrine (AL). The nested PCR-restriction fragment length polymorphism and the quantitative real-time PCR methodologies were used to determine the alleles of the Pfmdr1 and PfATPase6 genes and the Pfmdr1 copy number variation, respectively, in patients samples collected prior to treatment and at the reoccurrence of parasites during a 42-day follow-up. The Pfmdr1 haplotype 86N-184F-1246D was significantly associated (P < 0.00001) with treatment failures and was selected for among posttreatment samples obtained from patients with newly acquired or recrudescing infections (P < 0.00001; χ2 = 36.5) and in gametocytes (log rank statistic = 5; P = 0.0253) after treatment with AL. All pre- and posttreatment samples as well as gametocytes harbored a single copy of the Pfmdr1 gene and the wild-type allele (L89) at codon 89 of the PfATPase6 gene. These findings suggest that polymorphisms in the Pfmdr1 gene are under AL selection pressure. Pfmdr1 polymorphisms may result in reduction in the therapeutic efficacy of this newly adopted combination treatment for uncomplicated falciparum malaria in Saharan countries of Africa.

Acquired idiopathic thrombotic thrombocytopenic purpura (I-TTP) is a life-threatening microangiopathic disorder usually treated with therapeutic plasma exchange (TPE). The current study assessed the role of rituximab in the treatment of complicated I-TTP. The sequence of TTP events was compared in a group of I-TTP patients treated with TPE and a cohort of refractory or relapsed patients who also received rituximab. This retrospective evaluation included 45 I-TTP patients, treated between January 2000 and October 2013, who underwent at least 3 TPE procedures and were followed up until December 2013 or death. Thirty-one patients with an uncomplicated course received TPE only. Fourteen patients had a complicated course due to either a primary refractory/exacerbated disease (n = 5) or relapse (n = 9) and received rituximab together with TPE. The median number of TPE procedures performed in the first TTP episode in the uncomplicated cohort and groups with primary refractory or relapsed TTP was 11, 27 and 45, respectively. The relapse rates per follow-up year in the uncomplicated I-TTP, primary refractory and relapsed I-TTP groups were 0.18, 0.2 and 0.6 episodes, respectively. After rituximab therapy this rate dropped to 0.2 per year in the relapsed subgroup. In conclusion, about a quarter of patients with I-TTP had a complicated course and experienced a major benefit from rituximab in terms of effectiveness and safety. © 2015 S. Karger AG, Basel.

Contemporary Review of Risk-Stratified Management in Acute Uncomplicated and Complicated Diverticulitis.

2016-10-01

Acute colonic diverticulitis is a common clinical condition. Severity of the disease is based on clinical, laboratory, and radiological investigations and dictates the need for medical or surgical intervention. Recent clinical trials have improved the understanding of the natural history of the disease resulting in new approaches to and better evidence for the management of acute diverticulitis. We searched the Cochrane Library (years 2004-2015), MEDLINE (years 2004-2015), and EMBASE (years 2004-2015) databases. We used the search terms "diverticulitis, colonic" or "acute diverticulitis" or "divertic*" in combination with the terms "management," "antibiotics," "non-operative," or "surgery." Registers for clinical trials (such as the WHO registry and the https://clinicaltrials.gov/ ) were searched for ongoing, recruiting, or closed trials not yet published. Antibiotic treatment can be avoided in simple, non-complicated diverticulitis and outpatient management is safe. The management of complicated disease, ranging from a localized abscess to perforation with diffuse peritonitis, has changed towards either percutaneous or minimally invasive approaches in selected cases. The role of laparoscopic lavage without resection in perforated non-fecal diverticulitis is still debated; however, recent evidence from two randomised controlled trials has found a higher re-intervention in this group of patients. A shift in management has occurred towards conservative management in acute uncomplicated disease. Those with uncomplicated acute diverticulitis may be treated without antibiotics. For complicated diverticulitis with purulent peritonitis, the use of peritoneal lavage appears to be non-superior to resection.

To investigate in symptomatic uncomplicated diverticular disease the efficacy of symbiotics associated with a high-fibre diet on abdominal symptoms. This study was a multicentre, 6-mo randomized, controlled, parallel-group intervention with a preceding 4-wk washout period. Consecutive outpatients with symptomatic uncomplicated diverticular disease, aged 40-80 years, evaluated in 4 Gastroenterology Units, were enrolled. Symptomatic uncomplicated diverticular disease patients were randomized to two treatment arms A or B. Treatment A (n = 24 patients) received 1 symbiotic sachet Flortec(©) (Lactobacillus paracasei B21060) once daily plus high-fibre diet for 6 mo. Treatment B (n = 21 patients) received high-fibre diet alone for 6 mo. The primary endpoint was regression of abdominal symptoms and change of symptom severity after 3 and 6 mo of treatment. In group A, the proportion of patients with abdominal pain < 24 h decreased from 100% at baseline to 35% and 25% after 3 and 6 mo, respectively (P < 0.001). In group B the proportion of patients with this symptom decreased from 90.5% at baseline to 61.9% and 38.1% after 3 and 6 mo, respectively (P = 0.001). Symptom improvement became statistically significant at 3 and 6 mo in group A and B, respectively.The proportion of patients with abdominal pain >24 h decreased from 60% to 20% then 5% after 3 and 6 mo, respectively in group A (P < 0.001) and from 33.3% to 9.5% at both 3 and 6 mo in group B (P = 0.03). In group A the proportion of patients with abdominal bloating significantly decreased from 95% to 60% after 3 mo, and remained stable (65%) at 6-mo follow-up (P = 0.005) while in group B, no significant changes in abdominal bloating was observed (P = 0.11). After 6 mo of treatment, the mean visual analogic scale (VAS) values of both short-lasting abdominal pain (VAS, mean ± SD, group A: 4.6 ± 2.1 vs 2.2 ± 0.8, P = 0.02; group B: 4.6 ± 2.9 vs 2.0 ± 1.9, P = 0.03) and abdominal bloating (VAS, mean ± SD, group A: 5.3 ± 2.2 vs 3.0 ± 1.7, P = 0.005; group B: 5.3 ± 3.2 vs 2.3 ± 1.9, P = 0.006) decreased in both groups, whilst the VAS values of prolonged abdominal pain decreased in the Flortec(©) group, but remained unchanged in the high-fibre diet group (VAS, mean ± SD, group A: 6.5 ± 1.5 vs 4.5 ± 2.1, P = 0.052; group B: 4.5 ± 3.8 vs 5.5 ± 3.5). A high-fibre diet is effective in relieving abdominal symptoms in symptomatic uncomplicated diverticular disease. This treatment may be implemented by combining the high-fibre diet with Flortec(©).

Background It has been suggested that Schistosoma infection may be associated with Plasmodium falciparum infection or related reduction in haemoglobin level, but the nature of this interaction remains unclear. This systematic review synthesized evidence on the relationship of S. haematobium or S. mansoni infection with the occurrence of P. falciparum malaria, Plasmodium density and related reduction in haemoglobin level among children in sub-Saharan Africa (SSA). Methodology/Principal findings A systematic review in according with PRISMA guidelines was conducted. All published articles available in PubMed, Embase, Cochrane library and CINAHL databases before May 20, 2015 were searched without any limits. Two reviewers independently screened, reviewed and assessed all the studies. Cochrane Q and Moran’s I2 were used to assess heterogeneity and the Egger test was used to examine publication bias. The summary odds ratio (OR), summary regression co-efficient (β) and 95% confidence intervals (CI) were estimated using a random-effects model. Out of 2,920 citations screened, 12 articles (five cross-sectional, seven prospective cohort) were eligible to be included in the systematic review and 11 in the meta-analysis. The 12 studies involved 9,337 children in eight SSA countries. Eight studies compared the odds of asymptomatic/uncomplicated P. falciparum infection, two studies compared the incidence of uncomplicated P. falciparum infection, six studies compared P. falciparum density and four studies compared mean haemoglobin level between children infected and uninfected with S. haematobium or S. mansoni. Summary estimates of the eight studies based on 6,018 children showed a higher odds of asymptomatic/uncomplicated P. falciparum infection in children infected with S. mansoni or S. haematobium compared to those uninfected with Schistosoma (summary OR: 1.82; 95%CI: 1.41, 2.35; I2: 52.3%). The increase in odds of asymptomatic/uncomplicated P. falciparum infection among children infected with Schistosoma remained significant when subgroup analysis was conducted for S. haematobium (summary OR: 1.68; 95%CI: 1.18, 2.41; I2: 53.2%) and S. mansoni (summary OR: 2.15; 95%CI: 1.89, 2.46: I2: 0.0%) infection. However, the density of P. falciparum infection was lower in children co-infected with S. haematobium compared to those uninfected with Schistosoma (summary-β: -0.14; 95% CI: -0.24, -0.01; I2: 39.7%). The mean haemoglobin level was higher among children co-infected with S. haematobium and P. falciparum than those infected with only P. falciparum (summary-mean haemoglobin difference: 0.49; 95% CI: 0.04, 0.95; I2: 66.4%) Conclusions/Significance The current review suggests S. mansoni or S. haematobium co-infection may be associated with increased prevalence of asymptomatic/uncomplicated P. falciparum infection in children, but may protect against high density P. falciparum infection and related reduction in haemoglobin level.

Background Fever is the clinical hallmark of malaria disease. The Roll Back Malaria (RBM) movement promotes prompt, effective treatment of childhood fevers as a key component to achieving its optimistic mortality reduction goals by 2010. A neglected concern is how communities will access these new medicines promptly and the costs to poor households when they are located in rural areas distant to health services. Methods We assemble data developed between 2001 and 2002 in Kenya to describe treatment choices made by rural households to treat a child's fever and the related costs to households. Using a cost-of-illness approach, we estimate the expected cost of a childhood fever to Kenyan households in 2002. We develop two scenarios to explore how expected costs to households would change if more children were treated at a health care facility with an effective antimalarial within 48 hours of fever onset. Results 30% of uncomplicated fevers were managed at home with modern medicines, 38% were taken to a health care facility (HCF), and 32% were managed at home without the use of modern medicines. Direct household cash expenditures were estimated at $0.44 per fever, while the total expected cost to households (cash and time) of an uncomplicated childhood fever is estimated to be $1.91. An estimated mean of 1.42 days of caretaker time devoted to each fever accounts for the majority of household costs of managing fevers. The aggregate cost to Kenyan households of managing uncomplicated childhood fevers was at least $96 million in 2002, equivalent to 1.00% of the Kenyan GDP. Fewer than 8% of all fevers were treated with an antimalarial drug within 24 hours of fever onset, while 17.5% were treated within 48 hours at a HCF. To achieve an increase from 17.5% to 33% of fevers treated with an antimalarial drug within 48 hours at a HCF (Scenario 1), children already being taken to a HCF would need to be taken earlier. Under this scenario, direct cash expenditures would not change, and total household costs would fall slightly to $1.86 because caretakers also save time with prompt treatment if the child has malaria. Conclusion The management of uncomplicated childhood fevers imposes substantial costs on Kenyan households. Achieving substantial improvements in the numbers of fevers treated within 48 hours at a HCF with an effective antimalarial drug (Scenario 1) will not impose additional costs on households. Achieving additional improvements in fevers treated promptly at a HCF (Scenario 2) will impose additional costs on some households roughly equal to average cash expenses for transportation to a HCF. Additional financing mechanisms that further reduce the costs of accessing care at a HCF and/or that make artemisinin-based combination therapies (ACTs) accessible for home management need to be developed and evaluated as a top priority.

With increasing parasite drug resistance, the WHO has updated treatment recommendations for falciparum malaria including in pregnancy. This review assesses the evidence for choice of treatment for pregnant women. Relevant studies, primarily those published since 2010, were identified from reference databases and were used to identify secondary data sources. Expert commentary: WHO recommends use of intravenous artesunate for severe malaria, quinine-clindamycin for uncomplicated malaria in first trimester, and artemisinin combination therapy for uncomplicated malaria in second/third trimesters. Because fear of adverse outcomes has often excluded pregnant women from conventional drug development, available data for novel therapies are usually based on preclinical studies and cases of inadvertent exposure. Changes in antimalarial drug disposition in pregnancy have been observed but are yet to be translated into specific treatment recommendations. Such targeted regimens may become important as parasite resistance demands that drug exposure is optimized.

Timing of prophylactic surgery in prevention of diverticulitis recurrence: a cost-effectiveness analysis.

PubMed

Richards, Robert J; Hammitt, James K

2002-09-01

Although surgery is recommended after two or more attacks of uncomplicated diverticulitis, the optimal timing for surgery in terms of cost-effectiveness is unknown. A Markov model was used to compare the costs and outcomes of performing surgery after one, two, or three uncomplicated attacks in 60-year-old hypothetical cohorts. Transition state probabilities were assigned values using published data and expert opinion. Costs were estimated from Medicare reimbursement rates. Surgery after the third attack is cost saving, yielding more years of life and quality adjusted life years at a lower cost than the other two strategies. The results were not sensitive to many of the variables tested in the model or to changes made in the discount rate (0-5%). In conclusion, performing prophylactic resection after the third attack of diverticulitis is cost saving in comparison to resection performed after the first or second attacks and remains cost-effective during sensitivity analysis.

AIM--To determine serum laminin concentrations in patients with uncomplicated Plasmodium falciparum malaria. METHODS--An enzyme linked immunosorbent assay (ELISA) was used to determine serum laminin concentrations in 54 patients with acute uncomplicated P falciparum malaria during and after treatment, and in 17 control subjects in Bangkok, Thailand. RESULTS--Raised concentrations of soluble laminin were observed in patients (mean (SD) concentration 628 (225) ng/ml), compared with normal controls (490 (116) ng/ml), during the acute phase of the disease. During treatment, serum laminin concentrations decreased and returned to normal within three days. Serum laminin concentrations were correlated with parasite counts before treatment, and with the serum concentration of soluble intercellular adhesion molecule-1 (ICAM-1), soluble E-selectin, and soluble tumour necrosis factor receptor at 55 kilodaltons. CONCLUSIONS--These findings are compatible with an increased production or release of laminin in P falciparum malaria, which could indicate a role for the subendothelial basement membrane in the pathogenesis of the disease.

2014-01-01

Hemorrhoids are one of the most common ailments known. Often described as “varicose veins of the anus and rectum”, hemorrhoids are enlarged, bulging blood vessels in, and about the anus and lower rectum. About 75% of people will have hemorrhoids at some point in their lives. This paper shares the results from the clinical evaluation conducted to study effects of cryotherapy in treating uncomplicated hemorrhoids. The device used in the study is based on topically-applied cold therapy which can produce vasoconstriction in the tissues, tissue hypoxia, analgesia, and muscle relaxation. Cryotherapy was shown to be statistically similar or superior to proctology ointment in some of the parameters studied such as reduction of pain and hemorrhage. Overall it was observed that cryotherapy device contributes to improving the quality of life of patients with hemorrhoids. PMID:24474845

Pathogenetic aspects of uncomplicated urinary tract infection: recent advances.

PubMed

Fünfstück, R; Smith, J W; Tschäpe, H; Stein, G

1997-01-01

Urinary tract infections mostly are caused by Enterobacteriaceae; E. coli dominating in 80-90% for uncomplicated diseases. Microorganisms possessing the ability to colonize the uroepithelium (fimbriae/pili) and to cytotoxically damage cells and tissue (hemolysin) may initiate acute infection. Properties such as serum resistance, iron sequesteration, hydroxamate production and the presence of K-antigen are found in strains which persist in the host without initiating clinical symptoms. The ability of bacteria to adhere to cells of the epithelial boundary layer of the host organisms is of initial importance in the origin and progress of an infection. A variety of specific factors, e.g. glycolipids on the surface of the uroepithelium as well as cellular and humoral disorders of immunoreactions in the host determine the course of a disease. The immune response may ameliorate clinical symptoms and select urovirulent characteristics of the causative microorganism in recurrent diseases.

Chronic pain occurs in 20-30% of patients after hernia surgery. As a consequence of this chronic pain, almost one third of patients have limitations in daily activities. Frequency and severity of this pain varies with different techniques of hernia repair. The objective of this study was to compare polypropylene suture and skin staples for securing mesh in uncomplicated ventral hernioplasty in terms of acute and chronic postoperative pain and to compare the time taken for mesh fixation between polypropylene sutures and skin stapler in ventral hernioplasty. This study was conducted in Surgery Department of Dow University Hospital, Dow University of Health Sciences, Ojha Campus and included 53 patients from Jan 2015 to Dec 2016, after taking informed consent. All patients were operated under general anesthesia by the same surgical team. Patients were randomized into two groups; in one group mesh fixed with 2/0 polypropylene suture while in other group mesh stapler was used. Time taken to apply mesh was noted in minutes from laying the mesh over anterior rectus sheath to completion of fixation by either method. The severity of post-operative pain was measured with VAS (1-10) after one week, one month and after one year after surgery. Data was analysed using SPSS version 17. Patient characteristics and operative outcome were similar in the two groups and statistically non-significant in both. Early postoperative pain was more after suture fixation but it was not statistically significant. Mean ± SD pain score was after one week 3.47±2.7 after sutures while 2.91±1.88 after stapler. After four weeks, 0.40±0.49 after suture while 0.35±0.48 after stapler fixation. In both study groups 30-34% of the patients felt some pain in follow-up after one year. Severity of pain was 0.60±0.62 after suture while 1.65±1.94 after stapler fixation which is statistically significant as well (p<0.007). Mean operative time was 15.33±6.33 minutes for suture fixation while 1.56±0.41 minutes for fixation by staples, p-value < 0.001. The method of fixation does not appear to cause significant difference in early post-operative pain but chronic pain is more after stapler fixation of mesh. However, operative time was reduced significantly in staple fixation group as compared to suture fixation group.

The relationship between malaria infection and nutritional status is complex and previous studies suggest malaria may increase the incidence and severity of malnutrition while malnutrition may increase the risk of malaria infection. Here, we report bi-directional associations between malaria and nutritional status among children with uncomplicated severe acute malnutrition (SAM). The present study is a secondary analysis of a randomized controlled trial for the treatment of uncomplicated SAM in Niger. Children between 6-59 months were enrolled and followed for 12 weeks. Malaria infection was assessed using an HRP2 rapid diagnostic test at admission and at any follow-up visit with fever. We assessed the association of 1) nutritional status at admission on malaria incidence using Cox proportional hazards regression, and 2) malaria infection at admission on nutritional recovery, weight and height gain using linear regression. Of 2,399 children included in the analysis, 1,327 (55.3%) were infected with malaria at admission. Malaria incidence was 12.1 cases per 100 person-months among those without malaria infection at admission. Nutritional status at admission was not associated with malaria incidence. Children with malaria infection at admission, subsequently treated with an artemisinin based combination therapy, had increased weight gain (0.38 g/kg/day, 95% confidence interval [CI] 0.07 to 0.69) and reduced height gain (-0.002 mm/day, 95% CI -0.004 to -0.0008). Malaria infection was common among children treated for uncomplicated SAM. Malaria infection may impair height gain. Proper medical and nutritional management should be assured to prevent adverse effects of malaria infection.

Assessment of urinary extracellular vesicles including exosomes and microparticles (MPs) is an emerging approach for non-invasive detection of renal injury. We have previously reported that podocyte-derived MPs are increased in diabetic mice in advance of albuminuria. Here, we hypothesised that type 1 diabetes and acute hyperglycaemia would increase urinary podocyte MP levels in uncomplicated diabetes. In this post hoc exploratory analysis, we examined archived urine samples from normoalbuminuric patients with uncomplicated type 1 diabetes studied under clamped euglycaemia and hyperglycaemia and compared with healthy controls. Urinary vesicles were assessed by electron microscopy and nanoparticle tracking while podocyte MPs were assessed by flow cytometry. Neither vesicle size nor total number were significantly altered in type 1 diabetes or acute hyperglycaemia. By contrast, urinary podocyte MP levels were higher in type 1 diabetes (0.47 [0.00-3.42] MPs/μmol creatinine [Cr]) compared with healthy controls (0.00 [0.00-0.00] MPs/μmol Cr, p < 0.05) and increased under hyperglycaemic clamp (0.36 [0.00-4.15] MPs/μmol Cr during euglycaemia vs 2.70 [0.00-15.91] MPs/μmol Cr during hyperglycaemia, p < 0.05). Levels of urinary albumin to creatinine ratio and nephrin (surrogates of podocyte injury) were unchanged by type 1 diabetes or acute hyperglycaemia. Taken together, our data show that urinary podocyte MP levels are higher in patients with type 1 diabetes in advance of changes in other biomarkers (albuminuria, nephrin). Examination of podocyte MPs may serve as an early biomarker of glomerular injury in uncomplicated type 1 diabetes.

To assess whether immediate (0h), intermediate (after 6h) or delayed (after 24h) removal of an indwelling urinary catheter after uncomplicated abdominal hysterectomy can affect the rate of re-catheterization due to urinary retention, rate of urinary tract infection, ambulation time and length of hospital stay. Prospective randomized controlled trial conducted at Suez Canal University Hospital, Egypt. Two hundred and twenty-one women underwent total abdominal hysterectomy for benign gynecological diseases and were randomly allocated into three groups. Women in group A (73 patients) had their urinary catheter removed immediately after surgery. Group B (81 patients) had the catheter removed 6h post-operatively while in group C (67 patients) the catheter was removed after 24h. The main outcome measures were the frequency of urinary retention, urinary tract infections, ambulation time and length of hospital stay. There was a significantly higher number of urinary retention episodes requiring re-catheterization in the immediate removal group compared to the intermediate and delayed removal groups (16.4% versus 2.5% and 0% respectively). Delayed urinary catheter removal was associated with a higher incidence of urinary tract infections (15%), delayed ambulation time (10.3h) and longer hospital stay (5.6 days) compared to the early (1.4%, 4.1h and 3.2 days respectively) and intermediate (3.7%, 6.8h and 3.4 days respectively) removal groups. Removal of the urinary catheter 6h postoperatively appears to be more advantageous than early or late removal in cases of uncomplicated total abdominal hysterectomy.

The incidence of diverticulosis and diverticular disease of the colon, including diverticulitis, is increasing worldwide, and becoming a significant burden on national health systems. Treatment of patients with diverticulosis and DD is generally based on high-fibre diet and antibiotics, respectively. However, new pathophysiological knowledge suggests that further treatment may be useful. To review the current treatment of diverticulosis and diverticular disease. A search of PubMed and Medline databases was performed to identify articles relevant to the management of diverticulosis and diverticular disease. Major international conferences were also reviewed. Two randomised controlled trials (RCT) found the role of antibiotics in managing acute diverticulitis to be questionable, particularly in patients with no complicating comorbidities. One RCT found mesalazine to be effective in preventing acute diverticulitis in patients with symptomatic uncomplicated diverticular disease. The role of rifaximin or mesalazine in preventing diverticulitis recurrence, based on the results of 1 and 4 RCTs, respectively, remains unclear. RCTs found rifaximin and mesalazine to be effective in treating symptomatic uncomplicated diverticular disease. The use of probiotics in diverticular disease and in preventing acute diverticulitis occurrence/recurrence appears promising but unconclusive. Finally, the role of fibre in treating diverticulosis remains unclear. Available evidence suggests that antibiotics have a role only in the treatment of complicated diverticulitis. It appears to be some evidence for a role for rifaximin and mesalazine in treating symptomatic uncomplicated diverticular disease. Finally, there is not currently adequate evidence to recommend any medical treatment for the prevention of diverticulitis recurrence. © 2015 John Wiley & Sons Ltd.

To estimate the gestational age and birth weight centiles of babies delivered normally, without any obstetric intervention, in women with uncomplicated singleton pregnancies establishing spontaneous onset of labour. Consecutive women with uncomplicated singleton pregnancies, attending the Academic Obstetrics and Gynecology Unit of the Teaching Hospital Mahamodara Galle, Sri Lanka, with confirmed dates and establishing spontaneous onset of labor and delivering vaginally between gestational age of 34 - 41 weeks, without any obstetric intervention , during the period September 2013 to February 2014 were studied. The gestational age at spontaneous onset of labor and vaginal delivery and the birth weights of the babies were recorded. There were 3294 consecutive deliveries during this period, and of them 1602 (48.6%) met the inclusion criteria. Median gestational age at delivery was 275 days (range 238-291 days, IQR 269 to 280 days) and the median birth weight was 3000 g (range1700g - 4350g; IQR 2750-3250g). The 10th, 50th and 90th birth weight centiles of the babies delivered at a gestational age of 275 days were approximately 2570g, 3050g and 3550g respectively. The median gestational age among women with uncomplicated singleton pregnancies who established spontaneous onset of labor and delivered vaginally, without any obstetric intervention, was approximately five days shorter than the traditionally accepted 280 days. At a gestational age of 275 days, the mean birth weight was approximately 3038g and the 50th centile of the birth weight of the babies delivered was approximately 3050g.

Dihydroartemisinin-piperaquine is a new, highly effective, and well-tolerated combination treatment for uncomplicated falciparum malaria. The lipophilic characteristic of piperaquine suggests that administration together with fat will increase the oral bioavailability of the drug, and this has been reported for healthy volunteers. This pharmacokinetic study monitored 30 adult patients with uncomplicated falciparum malaria for 4.5 months to evaluate the effects of the concomitant intake of fat on the total piperaquine exposure. The fixed-drug combination of dihydroartemisinin-piperaquine was given with water to fasting patients (n = 15) or was coadministered with 200 ml milk containing 6.4 g fat (n = 15). The drug combination was generally well tolerated, and there were no severe adverse effects reported for either group during the study. Total piperaquine exposure (area under the concentration-time curve from zero to infinity [AUC0-∞]; results are given as medians [ranges]) were not statistically different between fed (29.5 h · μg/ml [20.6 to 58.7 h · μg/ml]) and fasting (23.9 h · μg/ml [11.9 to 72.9 h · μg/ml]) patients, but the interindividual variation was reduced in the fed group. Overall, none of the pharmacokinetic parameters differed statistically between the groups. Total piperaquine exposure correlated well with the day 7 concentrations in the fasted group, but the fed group showed a poor correlation. In conclusion, the coadministration of 6.4 g fat did not have any significant effect on piperaquine pharmacokinetics in the treatment of uncomplicated malaria. PMID:21709087

Short dietary assessment improves muscle dysfunction identification by Geriatric Nutritional Risk Index in uncomplicated institutionalised patients over 70 years old.

To possibly investigate the validity of the Geriatric Nutritional Risk Index (GNRI) in predicting muscle dysfunction among the uncomplicated elderly when coupled and compared with short dietary assessment. A total of 130 (61 males and 69 females) stable-weight, over 70-years-old elderly patients were studied according to anthropometry, handgrip strength (HG) and simple dietary assessment, expressed as oral (percentage of food consumed to that delivered) and protein (g/kg/day) intakes. For the overall population, HG and strength for centimetres of arm muscle area (HG/AMA) significantly correlated with age, GNRI and nutrients intake (p<0.001). In gender-separated analyses, these associations were less evident for males than females, which were older (p<0.0001) and presented lower strength and intakes (p<0.0001). Patients in the lowest tertile of oral intake (<68%) were more likely (p<0.0001) to have low HG and HG/AMA than those at severe/moderate nutritional risk (GNRI<92; p<0.01). In multivariate models, being an aged female significantly predicted muscle dysfunction. For the overall population, HG was significantly associated with GNRI (p<0.05) and oral intake (p<0.0001), while HG/AMA was independently associated with GNRI (p<0.001) and protein intake (p<0.0001). The validity of GNRI in predicting muscle dysfunction is confirmed also in the uncomplicated elderly. Though, oral intake appears an even better predictor. A frequent evaluation of its changes should be considered, particularly when concomitant high risk (GNRI<92) is scored.

Caesarean section among the Yoruba of western Nigerian is surrounded by a lot of fears, miseries, aversion, guilt and misconceptions for reasons varying from the desire by women to have a natural vaginal birth, fear of surgery, morbidity and deaths from the operation and prolonged hospital stay. To examine issues of reduced hospital stay following Caesarean section with a view of making the operation more acceptable and proffering solution to some of the problems faced by women when Caesarean section is indicated. A prospective case control study. Wesley Guild Hospital, Ilesha, Nigeria from 1st July, 1997 to 30th June, 1998. One hundred consecutive patients who had uncomplicated Caesarean section, randomised into two groups of short (three days) and prolonged (seven to eight days) hospital stay respectively. Observations of patients in both groups were made by an independent observer on day seven post-operation and the main outcomes measured included: wound infection rates, ability to maintain erect posture, mood changes, neonatal sepsis rate, immunisation rate of the neonates and average hospital bills. The findings revealed that wound infection rates of six per cent and ten per cent among the short and prolonged hospitalised patients respectively are not significantly different. Patients with short stay have better erect posture, lower incidence of depressive mood, lower neonatal sepsis rate, lower hospital bill and are more satisfied with early home discharge. Embracing the concept of early home discharge after Caesarean section in uncomplicated cases may remove some of the psychological upsets and economical impediments associated with the operation and make the operation more acceptable.

Cutaneous leishmaniasis (CL) is a tropical disease that affects millions of individuals worldwide. The current drugs for CL may be effective but have serious side effects; hence, alternatives are urgently needed. Although plant-derived materials are used for the treatment of various diseases in 80% of the global population, the validation of these products is essential. Gelatin capsules containing dried Artemisia annua leaf powder were recently developed as a new herbal formulation (totum) for the oral treatment of malaria and other parasitic diseases. Here, we aimed to determine the usefulness of A. annua gel capsules in CL. The antileishmanial activity and cytotoxicity of A. annua L. capsules was determined via in vitro and in vivo studies. Moreover, a preliminary evaluation of its therapeutic potential as antileishmanial treatment in humans was conducted in 2 patients with uncomplicated CL. Artemisia annua capsules showed moderate in vitro activity in amastigotes of Leishmania (Viannia) panamensis; no cytotoxicity in U-937 macrophages or genotoxicity in human lymphocytes was observed. Five of 6 (83.3%) hamsters treated with A. annua capsules (500mg/kg/day) for 30 days were cured, and the 2 examined patients were cured 45 days after initiation of treatment with 30g of A. annua capsules, without any adverse reactions. Both patients remained disease-free 26 and 24 months after treatment completion. Capsules of A. annua L. represent an effective treatment for uncomplicated CL, although further randomized controlled trials are needed to validate its efficacy and safety.

The burden of malaria remains high for children in parts of Africa despite the use of insecticide-treated bed nets (ITNs). Chemoprevention has the potential of reducing the malaria burden; however, limited data exist on the efficacy and safety of anti-malarial therapy in the setting of chemoprevention. 600 children 4-5 months of age were enrolled in Tororo, Uganda, an area of high transmission intensity. Participants were given ITNs, and caregivers instructed to bring their child to a study clinic whenever they were ill. Starting at six months of age, 579 were randomized to no chemoprevention, monthly sulphadoxine-pyrimethamine (SP), daily trimethoprim-sulphamethoxazole (TS), or monthly dihydroartemisinin-piperaquine (DP). Study drugs were administered unsupervised at home until 24 months of age. Episodes of uncomplicated malaria were treated with artemether-lumefantrine (AL) with active follow-up for 28 days. The cumulative risk of recurrent malaria within 84 days and the risk of adverse events within 28 days were compared across study arms using a Cox proportional hazards model and generalized estimating equations, respectively. A total of 1007, 919, 736, and 451 episodes of malaria were treated in the no chemoprevention, SP, TS, and DP arms, respectively. Only 19 (0.6%) treatments were for severe malaria. Early response to therapy with AL was excellent with 96.5% fever clearance and 99.4% parasite clearance by day 3. However, over 50% of AL treatments were followed by recurrent parasitaemia within 28 days. Compared to the no chemoprevention arm, the cumulative risk of recurrent malaria within 84 days following treatment of uncomplicated malaria with AL was significantly lower in the DP arm (HR = 0.77, 95% CI 0.63-0.95, p = 0.01) but not the SP or TS arms. Compared to the no chemoprevention arm, none of the chemopreventive regimens were associated with an increased risk of adverse events following treatment of malaria with AL. The risk of severe malaria was very low in this cohort of young children living in a high transmission setting. In the setting of chemoprevention, treatment of uncomplicated malaria with AL was safe and efficacious, with moderate protection against recurrent malaria among children assigned monthly DP.

Recent malaria epidemics in KwaZulu-Natal indicate that effective anti-malarial therapy is essential for malaria control. Although artemether-lumefantrine has been used as first-line treatment for uncomplicated Plasmodium falciparum malaria in northern KwaZulu-Natal since 2001, its efficacy has not been assessed since 2002. The objectives of this study were to quantify the proportion of patients treated for uncomplicated P. falciparum malaria with artemether-lumefantrine who failed treatment after 28 days, and to determine the prevalence of molecular markers associated with artemether-lumefantrine and chloroquine resistance. An observational cohort of 49 symptomatic patients, diagnosed with uncomplicated P. falciparum malaria by rapid diagnostic test, had blood taken for malaria blood films and P. falciparum DNA polymerase chain reaction (PCR). Following diagnosis, patients were treated with artemether-lumefantrine (Coartem®) and invited to return to the health facility after 28 days for repeat blood film and PCR. All PCR P. falciparum positive samples were analysed for molecular markers of lumefantrine and chloroquine resistance. Of 49 patients recruited on the basis of a positive rapid diagnostic test, only 16 were confirmed to have P. falciparum by PCR. At follow-up, 14 were PCR-negative for malaria, one was lost to follow-up and one blood specimen had insufficient blood for a PCR analysis. All 16 with PCR-confirmed malaria carried a single copy of the multi-drug resistant (mdr1) gene, and the wild type asparagine allele mdr1 codon 86 (mdr1 86N). Ten of the 16 samples carried the wild type haplotype (CVMNK) at codons 72-76 of the chloroquine resistance transporter gene (pfcrt); three samples carried the resistant CVIET allele; one carried both the resistant and wild type, and in two samples the allele could not be analysed. The absence of mdr1 gene copy number variation detected in this study suggests lumefantrine resistance has yet to emerge in KwaZulu-Natal. In addition, data from this investigation implies the possible re-emergence of chloroquine-sensitive parasites. Results from this study must be viewed with caution, given the extremely small sample size. A larger study is needed to accurately determine therapeutic efficacy of artemether-lumefantrine and resistance marker prevalence. The high proportion of rapid diagnostic test false-positive results requires further investigation.

Impact of retreatment with an artemisinin-based combination on malaria incidence and its potential selection of resistant strains: study protocol for a randomized controlled clinical trial

PubMed Central

2013-01-01

Background Artemisinin-based combination therapy is currently recommended by the World Health Organization as first-line treatment of uncomplicated malaria. Recommendations were adapted in 2010 regarding rescue treatment in case of treatment failure. Instead of quinine monotherapy, it should be combined with an antibiotic with antimalarial properties; alternatively, another artemisinin-based combination therapy may be used. However, for informing these policy changes, no clear evidence is yet available. The need to provide the policy makers with hard data on the appropriate rescue therapy is obvious. We hypothesize that the efficacy of the same artemisinin-based combination therapy used as rescue treatment is as efficacious as quinine + clindamycin or an alternative artemisinin-based combination therapy, without the risk of selecting drug resistant strains. Design We embed a randomized, open label, three-arm clinical trial in a longitudinal cohort design following up children with uncomplicated malaria until they are malaria parasite free for 4 weeks. The study is conducted in both the Democratic Republic of Congo and Uganda and performed in three steps. In the first step, the pre-randomized controlled trial (RCT) phase, children aged 12 to 59 months with uncomplicated malaria are treated with the recommended first-line drug and constitute a cohort that is passively followed up for 42 days. If the patients experience an uncomplicated malaria episode between days 14 and 42 of follow-up, they are randomized either to quinine + clindamycin, or an alternative artemisinin-based combination therapy, or the same first-line artemisinin-based combination therapy to be followed up for 28 additional days. If between days 14 and 28 the patients experience a recurrent parasitemia, they are retreated with the recommended first-line regimen and actively followed up for another 28 additional days (step three; post-RCT phase). The same methodology is followed for each subsequent failure. In any case, all patients without an infection at day 28 are classified as treatment successes and reach a study endpoint. The RCT phase allows the comparison of the safety and efficacy of three rescue treatments. The prolonged follow-up of all children until they are 28 days parasite-free allows us to assess epidemiological-, host- and parasite-related predictors for repeated malaria infection.

Appropriate diagnosis and treatment are essential for reducing malaria mortality. A cross-sectional outpatient health facility (HF) survey was conducted in southern Malawi from January to March 2015 to determine appropriate malaria testing and treatment practices four years after implementation of a policy requiring diagnostic confirmation before treatment. Enrolled patients were interviewed, examined and had their health booklet reviewed. Health workers (HWs) were asked about training, supervision and access to the 2013 national malaria treatment guidelines. HFs were assessed for malaria diagnostic and treatment capacity. Weighted descriptive analyses and logistic regression of patient, HW and HF characteristics related to testing and treatment were performed. An evaluation of 105 HFs, and interviews of 150 HWs and 2342 patients was completed. Of 1427 suspect uncomplicated malaria patients seen at HFs with testing available, 1072 (75.7%) were tested, and 547 (53.2%) tested positive. Testing was more likely if patients spontaneously reported fever (odds ratio (OR) 2.6; 95% confidence interval (CI) 1.7-4.0), headache (OR 1.5; 95% CI 1.1-2.1) or vomiting (OR 2.0; 95% CI 1.0-4.0) to HWs and less likely if they reported skin problems (OR 0.4; 95% CI 0.2-0.6). Altogether, 511 (92.7%) confirmed cases and 98 (60.3%) of 178 presumed uncomplicated malaria patients (at HFs without testing) were appropriately treated, while 500 (96.6%) of 525 patients with negative tests did not receive anti-malarials. Only eight (5.7%) suspect severe malaria patients received appropriate pre-referral treatment. Appropriate treatment was more likely for presumed uncomplicated malaria patients (at HFs without testing) with elevated temperature (OR 1.5/1 °C increase; 95% CI 1.1-1.9), who reported fever to HWs (OR 5.7; 95% CI 1.9-17.6), were seen by HWs with additional supervision visits in the previous 6 months (OR 1.2/additional visit; 95% CI 1.0-1.4), or were seen by older HWs (OR 1.1/year of age; 95% CI 1.0-1.1). Correct testing and treatment practices were reasonably good for uncomplicated malaria when testing was available. Pre-referral treatment for suspect severe malaria was unacceptably rare. Encouraging HWs to elicit and appropriately respond to patient symptoms may improve practices.

“…still waiting for chloroquine”: the challenge of communicating changes in first-line treatment policy for uncomplicated malaria in a remote Kenyan district

Background Widespread parasite resistance to first-line treatment for uncomplicated malaria leads to introduction of new drug interventions. Introducing such interventions is complex and sensitive because of stakeholder interests and public resistance. To enhance take up of such interventions, health policy communication strategies need to deliver accurate and accessible information to empower communities with necessary information and address problems of cultural acceptance of new interventions. Objectives To explore community understanding of policy changes in first-line treatment for uncomplicated malaria in Kenya; to evaluate the potential role of policy communication in influencing responses to changes in first-line treatment policy. Methods Data collection involved qualitative strategies in a remote district in the Kenyan Coast: in-depth interviews (n = 29), focus group discussions (n = 14), informal conversations (n = 11) and patient narratives (n = 8). Constant comparative method was used in the analysis. Being malaria-prone and remotely located, the district offered an ideal area to investigate whether or not and how policy communication about a matter as critical as change of treatment policy reaches vulnerable populations. Results Three years after initial implementation (2009), there was limited knowledge or understanding regarding change of first-line treatment from sulphadoxine-pyrimethamine (SP) to artemether-lumefantrine (AL) for treatment of uncomplicated malaria in the study district. The print and electronic media used to create awareness about the drug change appeared to have had little impact. Although respondents were aware of the existence of AL, the drug was known neither by name nor as the official first-line treatment. Depending on individuals or groups, AL was largely viewed negatively. The weaknesses in communication strategy surrounding the change to AL included poor choice of communication tools, confusing advertisements of other drugs and conflicts between patients and providers. Conclusion Effective health policy communication is important for the uptake of new drug interventions and adherence to treatment regimens. Besides, prompt access to effective treatment may not be achieved if beneficiaries are not adequately informed about treatment policy changes. Future changes in treatment policy should ensure that the communication strategy is designed to pass sustained, accurate and effective messages that account for local contexts. PMID:25005337

Conservative treatment of uncomplicated or mild diverticulitis usually includes antibiotic therapy. It is, however, uncertain whether patients with acute diverticulitis indeed benefit from antibiotics. In most guidelines issued by professional organizations antibiotics are considered mandatory in the treatment of mild diverticulitis. This advice lacks evidence and is merely based on experts' opinion. Adverse effects of the use of antibiotics are well known, including allergic reactions, development of bacterial resistance to antibiotics and other side-effects. A randomized multicenter pragmatic clinical trial comparing two treatment strategies for uncomplicated acute diverticulitis. I) A conservative strategy with antibiotics: hospital admission, supportive measures and at least 48 hours of intravenous antibiotics which subsequently are switched to oral, if tolerated (for a total duration of antibiotic treatment of 10 days). II) A liberal strategy without antibiotics: admission only if needed on clinical grounds, supportive measures only. Patients are eligible for inclusion if they have a diagnosis of acute uncomplicated diverticulitis as demonstrated by radiological imaging. Only patients with stages 1a and 1b according to Hinchey's classification or "mild" diverticulitis according to the Ambrosetti criteria are included. The primary endpoint is time-to-full recovery within a 6-month follow-up period. Full recovery is defined as being discharged from the hospital, with a return to pre-illness activities, and VAS score below 4 without the use of daily pain medication. Secondary endpoints are proportion of patients who develop complicated diverticulitis requiring surgery or non-surgical intervention, morbidity, costs, health-related quality of life, readmission rate and acute diverticulitis recurrence rate. In a non-inferiority design 264 patients are needed in each study arm to detect a difference in time-to-full recovery of 5 days or more with a power of 85% and a confidence level of 95%. With an estimated one percent of patients lost to follow up, a total of 533 patients will be included. A clinically relevant difference of more than 5 days in time-to-full recovery between the two treatment strategies is not expected. The liberal strategy without antibiotics and without the strict requirement for hospital admission is anticipated to be more a more cost-effective approach. NCT01111253.

AIM: To evaluate the impact of mesalamine administration on inflammatory response in acute uncomplicated diverticulitis. METHODS: We conducted a single centre retrospective cohort study on patients admitted to our surgical department between January 2012 and May 2014 with a computed tomography -confirmed diagnosis of acute uncomplicated diverticulitis. A total of 50 patients were included in the analysis, 20 (study group) had received 3.2 g/d of mesalamine starting from the day of admission in addition to the usual standard treatment, 30 (control group) had received standard therapy alone. Data was retrieved from a prospective database. Our primary study endpoints were: C reactive protein mean levels over time and their variation from baseline (ΔCRP) over the first three days of treatment. Secondary end points included: mean white blood cell and neutrophile count over time, time before regaining of regular bowel movements (passing of stools), time before reintroduction of food intake, intensity of lower abdominal pain over time, analgesic consumption and length of hospital stay. RESULTS: Patients characteristics and inflammatory parameters were similar at baseline in the two groups. The evaluation of CRP levels over time showed, in treated patients, a distinct trend towards a faster decrease compared to controls. This difference approached statistical significance on day 2 (mean CRP 6.0 +/- 4.2 mg/dL and 10.0 +/- 6.7 mg/dL respectively in study group vs controls, P = 0.055). ΔCRP evaluation evidenced a significantly greater increment of this inflammatory marker in the control group on day 1 (P = 0.03). A similar trend towards a faster resolution of inflammation was observed evaluating the total white blood cell count. Neutrophile levels were significantly lower in treated patients on day 2 and on day 3 (P < 0.05 for both comparisons). Mesalamine administration was also associated with an earlier reintroduction of food intake (median 1.5 d and 3 d, study group vs controls respectively, P < 0.001) and with a shorter hospital stay (median 5 d and 5.5 d, study group vs controls respectively, P = 0.03). CONCLUSION: Despite its limitations, this study suggests that mesalamine may allow for a faster recovery and for a reduction of inflammatory response in acute uncomplicated diverticulitis.

Artemisinin-based combination therapy (ACT) is currently the most effective medicine for the treatment of uncomplicated malaria. Artemisinin has previously been shown to increase the clearance of Plasmodium falciparum in malaria patients with haemoglobin E trait, but it did not increase parasite inhibition in an in vitro study using haemoglobin AS erythrocytes. The current study describes the efficacy of artemisinin derivatives on P. falciparum clearance in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD), a haemoglobin enzyme deficiency, not yet studied in the same context, but nonetheless is a common in malaria endemic areas, associated with host protection against uncomplicated and severe malaria. The impact of G6PD deficiency on parasite clearance with ACT treatment was compared between G6PD-deficient patients and G6PD-normal group. Blood samples from children and adults participants (1 to 70 years old) with uncomplicated P. falciparum malaria residing in Kambila, Mali were analysed. Study participants were randomly assigned to receive either artemether-lumefantrine (Coartem®) or artesunate plus mefloquine (Artequin™). A restriction-fragment length polymorphism analysis of PCR-amplified DNA samples was used to identify the (A-) allele of the gene mutation responsible for G6PD deficiency (G6PD*A-). 470 blood samples were thus analysed and of these, DNA was extracted from 315 samples using the QIAamp kit for PCR to identify the G6PD*A- gene. The DNA amplified from 315 samples using PCR showed that G6PD*A- deficiency was present in 56 participants (17.8%). The distribution of the specific deficiency was 1%, 7% and, 9.8% respectively for homozygous, hemizygous, and heterozygous genotypes. Before treatment, the median parasitaemia and other baseline characteristics (mean haemoglobin, sex and age groups) between G6PD deficiency (hemizygous, heterozygous, and homozygous) and G6PD-normal participants were comparable (p > 0.05). After treatment, parasite clearance did not change significantly whether the participants were G6PD deficient or G6PD normal on day 1 (OR = 1.3; CI = 0.70-2.47; p > 0.05) and on day 2 (OR = 0.859; CI = 0.097-7.61; p > 0.05). The presence of G6PD deficiency does not appear to significantly influence the clearance of P. falciparum in the treatment of uncomplicated malaria using ACT.

Malaria is a leading cause of mortality, particularly in sub-Saharan African children. Prompt and efficacious treatment is important as patients may progress within a few hours to severe and possibly fatal disease. Chlorproguanil-dapsone-artesunate (CDA) was a promising artemisinin-based combination therapy (ACT), but its development was prematurely stopped because of safety concerns secondary to its associated risk of haemolytic anaemia in glucose-6-phosphate dehydrogenase (G6PD)-deficient individuals. The objective of the study was to assess whether CDA treatment and G6PD deficiency are risk factors for a post-treatment haemoglobin drop in African children<5 years of age with uncomplicated malaria. This case-control study was performed in the context of a larger multicentre randomized clinical trial comparing safety and efficacy of four different ACT in children with uncomplicated malaria. Children, who after treatment experienced a haemoglobin drop≥2 g/dl (cases) within the first four days (days 0, 1, 2, and 3), were compared with those without an Hb drop (controls). Cases and controls were matched for study site, sex, age and baseline haemoglobin measurements. Data were analysed using a conditional logistic regression model. G6PD deficiency prevalence, homo- or hemizygous, was 8.5% (10/117) in cases and 6.8% (16/234) in controls (p=0.56). The risk of a Hb drop≥2 g/dl was not associated with either G6PD deficiency (adjusted odds ratio (AOR): 0.81; p=0.76) or CDA treatment (AOR: 1.28; p=0.37) alone. However, patients having both risk factors tended to have higher odds (AOR: 11.13; p=0.25) of experiencing a Hb drop≥2 g/dl within the first four days after treatment, however this finding was not statistically significant, mainly because G6PD deficient patients treated with CDA were very few. In non-G6PD deficient individuals, the proportion of cases was similar between treatment groups while in G6PD-deficient individuals, haemolytic anaemia occurred more frequently in children treated with CDA (56%) than in those treated with other ACT (29%), though the difference was not significant (p=0.49). The use of CDA for treating uncomplicated malaria may increase the risk of haemolytic anaemia in G6PD-deficient children.

Projected impact of the ICD-10-CM/PCS conversion on longitudinal data and the Joint Commission Core Measures.

The transition from ICD-9-CM to ICD-10-CM/PCS is expected to result in longitudinal data discontinuities, as occurred with cause-of-death in 1999. The General Equivalence Maps (GEMs), while useful for suggesting potential maps do not provide guidance regarding the frequency of any matches. Longitudinal data comparisons can only be reliable if they use comparability ratios or factors which have been calculated using records coded in both classification systems. This study utilized 3,969 de-identified dually coded records to examine raw comparability ratios, as well as the comparability ratios between the Joint Commission Core Measures. The raw comparability factor results range from 16.216 for Nicotine dependence, unspecified, uncomplicated to 118.009 for Chronic obstructive pulmonary disease, unspecified. The Joint Commission Core Measure comparability factor results range from 27.15 for Acute Respiratory Failure to 130.16 for Acute Myocardial Infarction. These results indicate significant differences in comparability between ICD-9-CM and ICD-10-CM code assignment, including when the codes are used for external reporting such as the Joint Commission Core Measures. To prevent errors in decision-making and reporting, all stakeholders relying on longitudinal data for measure reporting and other purposes should investigate the impact of the conversion on their data.

Introduction into the NHS of magnetic sphincter augmentation: an innovative surgical therapy for reflux - results and challenges.

Introduction Gastro-oesophageal reflux disease (GORD) is a common, chronic debilitating condition. Surgical management traditionally involves fundoplication. Magnetic sphincter augmentation (MSA) is a new definitive treatment. We describe our experience of introducing this innovative therapy into NHS practice and report the early clinical outcomes. Methods MSA was introduced into NHS practice following successful acceptance of a cost-effective business plan and close observation of National Institute for Health and Care Excellence (NICE) recommendations for new procedures, including a carefully planned prospective data collection over a two-year follow-up period. Results Forty-seven patients underwent MSA over the 40-month period. Reflux health-related quality of life (GERD-HRQL) was significantly improved after the procedure and maintained at one- and two-year (P < 0.0001) follow-up. Drug dependency went from 100% at baseline to 2.6% and 8.7% after one and two years. High levels of patient satisfaction were reported. There were no adverse events. Conclusions MSA is highly effective in the treatment of uncomplicated GORD, with durable results and an excellent safety profile. This laparoscopic, minimally invasive procedure provides a good alternative for patients where surgical anatomy is unaltered. Our experience demonstrates that innovative technology can be incorporated into NHS practice with an acceptable business plan and compliance with NICE recommendations.

The purpose of this quality improvement project was to evaluate hypertension (HTN) management in patients 80 years of age and older who reside in a large, long-term care (LTC) facility. A retrospective chart audit was conducted on 75 charts of patients 80 years of age and older and who had a diagnosis of HTN. Using the 2011 American College of Cardiology Foundation/American Heart Association (ACCF/AHA) Expert Consensus Document on Management of Hypertension in the Elderly as a guide, blood pressure readings, significant comorbidities, and antihypertensive medication utilization were analyzed. LTC residents in this sample were often not treated according to expert recommendations. Specifically, analysis revealed overtreatment of uncomplicated HTN and undertreatment of those with comorbid conditions. Additionally, those with diabetes mellitus and chronic kidney disease were infrequently prescribed ace inhibitors/angiotensin receptor blockers, as recommended. Utilizing evidence-based practice (EBP) guidelines affords the best avenue for providing safe and effective treatment of HTN. While expert recommendations are available, researchers seldom recruit frail elders in LTC facilities into treatment investigations. In the absence of population-specific EBP guidelines, nurse practitioners must rely on expert opinion and diagnostic reasoning to individualize HTN treatment to this unique and vulnerable population. ©2016 American Association of Nurse Practitioners.

Profiles of impaired, spared, and recovered neuropsychologic processes in alcoholism.

Long-term chronic alcoholism is associated with disparate and widespread residual consequences for brain functioning and behavior, and alcoholics suffer a variety of cognitive deficiencies and emotional abnormalities. Alcoholism has heterogeneous origins and outcomes, depending upon factors such as family history, age, gender, and mental or physical health. Consequently, the neuropsychologic profiles associated with alcoholism are not uniform among individuals. Moreover, within and across research studies, variability among subjects is substantial and contributes to characteristics associated with differential treatment outcomes after detoxification. In order to refine our understanding of alcoholism-related impaired, spared, and recovered abilities, we focus on five specific functional domains: (1) memory; (2) executive functions; (3) emotion and psychosocial skills; (4) visuospatial cognition; and (5) psychomotor abilities. Although the entire brain might be vulnerable in uncomplicated alcoholism, the brain systems that are considered to be most at risk are the frontocerebellar and mesocorticolimbic circuitries. Over time, with abstinence from alcohol, the brain appears to become reorganized to provide compensation for structural and behavioral deficits. By relying on a combination of clinical and scientific approaches, future research will help to refine the compensatory roles of healthy brain systems, the degree to which abstinence and treatment facilitate the reversal of brain atrophy and dysfunction, and the importance of individual differences to outcome. © 2014 Elsevier B.V.

Varicella-zoster virus and herpes simplex virus types 1 and 2 are neurotropic viruses that can be reactivated after a surgical or stressful intervention. Although such cases are uncommon, consequences can be debilitating, and variable treatment responses merit consideration. We describe a 41-year-old male with a history of varicella-mediated skin eruptions, who presented with continuing right arm pain, burning, and numbness in a C6 dermatomal distribution following a C5-6 anterior cervical discectomy and fusion and epidural steroid injections. The operative course was uncomplicated and he was discharged home on postoperative day 1. Approximately ten days after surgery, the patient presented to the emergency department complaining of severe pain in his right upper extremity and a vesicular rash from his elbow to his second digit. He was started on Acyclovir and discharged home. On outpatient follow-up, his rash had resolved though his pain continued. The patient was started on a neuromodulating agent for chronic pain. This case adds to the limited literature regarding this rare complication, brings attention to the symptoms for proper diagnosis and treatment, and emphasizes the importance of prompt antiviral therapy. We suggest adding a neuromodulating agent to prevent long-term sequelae and resolve acute symptoms. PMID:24251050

To analyze serum biomarkers of CVD in selected patients with primary axial reflux of great saphenous vein in one or both lower limbs. Ninety-six patients affected by uncomplicated varicose veins, were enrolled in the study. A unilateral, primary axial reflux in great saphenous veins was detected in 54 patients (U-CVD group) and a bilateral one in 42 (B-CVD group). Sixty-five age and sex-matched subjects without venous reflux were enrolled as controls. Mean venous pressure of both lower limbs at the distal great saphenous vein (mGSVP) and venous reflux were measured by continuous-wave Doppler ultrasound and echoduplex scanning, respectively. Reactive Oxygen Species (ROS), tissue Plasminogen Activator (t-PA) and its Inhibitor 1 (PAI-1) activities, Hematocrit (HTC), White Blood Cells (WBC), Neutrophyls (NEU), Platelets (PLT), Fibrinogen (FIB) and Blood Viscosity (BV) were assessed in blood samples drawn from the antecubital vein. B-CVD group showed higher fibrinogen values (p < 0.005) and higher mean venous pressure (0 < 0.0001) in comparison to controls, while U-CVD did not. No difference was found between both groups and controls for all the other parameters. Increased fibrinogen levels in patients with bilateral varicose veins may represent an early warning signal, as it could be associated to the long-term progression of chronic venous disease.

To distinguish, in patients with Korsakoff syndrome (KS), the structural brain abnormalities shared with alcoholic patients without KS (AL), from those specific to KS. MRI data were collected in 11 alcoholic patients with KS, 34 alcoholic patients without KS, and 25 healthy control subjects (CS). Gray and white matter volumes were compared in the 3 groups using a voxel-based approach. A conjunction analysis indicated a large pattern of shared gray and white matter volume deficits in AL and KS. There were graded effects of volume deficits (KS < AL < CS) in the medial portion of the thalami, hypothalamus (mammillary bodies), left insula, and genu of the corpus callosum. Abnormalities in the left thalamic radiation were observed only in KS. Our results indicate considerable similarities in the pattern of gray and white matter damage in AL and KS. This finding confirms the widespread neurotoxic effect of chronic alcohol consumption. Only a few cerebral regions, including the medial thalami, mammillary bodies, and corpus callosum, were more severely damaged in KS than in AL. The continuum of macrostructural damage from AL to KS is therefore restricted to key brain structures. Longitudinal investigations are required to determine whether alcoholic patients with medial thalamic volumes that are comparable to those of patients with KS are at increased risk of developing KS.

The declining efficacy of chloroquine in the early 2000s in Ghana led to its replacement with artesunate/amodiaquine (AS/AQ) combination as first-line drug for treating uncomplicated malaria in 2005. Since then efficacy studies have been ongoing in the country to provide continuous data on the efficacy of AS/AQ and other alternative antimalarials (artemether/lumefantrine and dihyroartemisinin/piperaquine combinations) introduced in 2008. In vivo AS/AQ efficacy studies were conducted between June and October 2014 among children aged 6 months to 14 years, in two sentinel sites representing the forest and coastal zones of the country. The 2009 World Health Organization protocol for monitoring antimalarial drug efficacy was used in these studies. The studies showed an overall cumulative polymerase chain reaction-corrected day 28 cure rate of 97.2% (95% confidence interval [CI]: 93.6-99.1): 97.7% (95% CI: 92.0-99.7) within the forest zone and 96.7% (95% CI: 90.7-99.3) within the coastal zone ( P = 0.686). Prevalence of fever declined from 100% to < 4% after first day of treatment in both ecological zones. All children in the coastal zone had cleared parasites by day 2. Three children (3.2%) in the forest zone were parasitemic on day 2, whereas one child was parasitemic on day 3. Gametocytemia was absent in both zones after day 14, and mean hemoglobin concentration significantly increased from 10.3 g/dL (95% CI: 10.1-10.5) on day 0 to 11.8 g/dL (95% CI: 11.6-12.0) on day 28. We conclude that AS/AQ combination remains efficacious in the treatment of uncomplicated malaria in Ghana.

Little is known about how closely operative reports reflect what was actually performed during an operation, nor has the construction of operative reports been adequately studied with the aims of clarifying the objectives of those reports and improving their efficacy. We hypothesized that if more attention is paid to the objectives of operative reports, their content will more predictably contain the most relevant information, which might channel thinking in beneficial directions during performance of the operation. Multivariate analysis of 250 laparoscopic cholecystectomy operative reports (125 uncomplicated and 125 with bile duct injury). Academic research. University (105 cases) and community (145 cases) hospitals. Variations in content and design of operative reports. Cognitive task analysis of laparoscopic cholecystectomy was conducted, and a model operative report was generated and compared with the actual operative reports. Descriptions of key elements in adequate dissection of the Calot triangle were present in 24.8% and 0.0% of operative reports from uncomplicated and bile duct injury cases, respectively. Thorough dissection of the Calot triangle, identification of the cystic duct-infundibulum junction, and lateral retraction of the infundibulum correlated with uncomplicated cases, while irregular cues (eg, perceived anatomic or other deviations) correlated with bile duct injury cases. Current practice generates operative reports that vary widely in content and too often omit important elements. This research suggests that the construction of operative reports should be constrained such that the reports routinely include the fundamental goals of the operation and what was performed to meet them. Cognitive task analysis is based on the ways the mind controls the performance of tasks; it is an excellent method for determining the extra content needed in operative reports. The resulting designs should also serve as mental guidelines to facilitate learning and to enhance the safety of the operation.

Prompt and effective malaria treatment are key in reducing transmission, disease severity and mortality. With the current scale-up of artemisinin-based combination therapy (ACT) coverage, there is need to focus on challenges affecting implementation of the intervention. Routine indicators focus on utilization and coverage, neglecting implementation quality. A health system in rural Malawi was assessed for uncomplicated malaria treatment implementation in children. A cross-sectional health facility survey was conducted in six health centres around the Majete Wildlife Reserve in Chikwawa district using a health system effectiveness approach to assess uncomplicated malaria treatment implementation. Interviews with health facility personnel and exit interviews with guardians of 120 children under 5 years were conducted. Health workers appropriately prescribed an ACT and did not prescribe an ACT to 73% (95% CI 63-84%) of malaria rapid diagnostic test (RDT) positive and 98% (95% CI 96-100%) RDT negative children, respectively. However, 24% (95% CI 13-37%) of children receiving artemisinin-lumefantrine had an inappropriate dose by weight. Health facility findings included inadequate number of personnel (average: 2.1 health workers per 10,000 population), anti-malarial drug stock-outs or not supplied, and inconsistent health information records. Guardians of 59% (95% CI 51-69%) of children presented within 24 h of onset of child's symptoms. The survey presents an approach for assessing treatment effectiveness, highlighting bottlenecks which coverage indicators are incapable of detecting, and which may reduce quality and effectiveness of malaria treatment. Health service provider practices in prescribing and dosing anti-malarial drugs, due to drug stock-outs or high patient load, risk development of drug resistance, treatment failure and exposure to adverse effects.

Dihydroartemisinin-piperaquine (DhP) is highly recommended for the treatment of uncomplicated malaria. This study aims to compare the costs, health benefits and cost-effectiveness of DhP and artemether-lumefantrine (AL) alongside "do-nothing" as a baseline comparator in order to consider the appropriateness of DhP as a first-line anti-malarial drug for children in Tanzania. A cost-effectiveness analysis was performed using a Markov decision model, from a provider's perspective. The study used cost data from Tanzania and secondary effectiveness data from a review of articles from sub-Saharan Africa. Probabilistic sensitivity analysis was used to incorporate uncertainties in the model parameters. In addition, sensitivity analyses were used to test plausible variations of key parameters and the key assumptions were tested in scenario analyses. The model predicts that DhP is more cost-effective than AL, with an incremental cost-effectiveness ratio (ICER) of US$ 12.40 per DALY averted. This result relies on the assumption that compliance to treatment with DhP is higher than that with AL due to its relatively simple once-a-day dosage regimen. When compliance was assumed to be identical for the two drugs, AL was more cost-effective than DhP with an ICER of US$ 12.54 per DALY averted. DhP is, however, slightly more likely to be cost-effective compared to a willingness-to-pay threshold of US$ 150 per DALY averted. Dihydroartemisinin-piperaquine is a very cost-effective anti-malarial drug. The findings support its use as an alternative first-line drug for treatment of uncomplicated malaria in children in Tanzania and other sub-Saharan African countries with similar healthcare infrastructures and epidemiology of malaria.

Since 2005, the Togo National Malaria Control Programme has recommended two different formulations of artemisinin-based combination therapy (ACT), artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL), for the treatment of uncomplicated malaria. Regular efficacy monitoring of these two combinations is conducted every 2 or 3 years. This paper reports the latest efficacy assessment results and the investigation of mutations in the k13 propeller domain. The study was conducted in 2012-2013 on three sentinel sites of Togo (Lomé, Sokodé and Niamtougou). Children aged 6-59 months, who were symptomatically infected with Plasmodium falciparum, were treated with either AL (Coartem(®), Novartis Pharma, Switzerland) or ASAQ (Co-Arsucam(®), Sanofi Aventis, France). The WHO standard protocol for anti-malarial treatment evaluation was used. The primary end-point was 28-day adequate clinical and parasitological response (ACPR), corrected to exclude reinfection using polymerase-chain reaction (PCR) genotyping. A total of 523 children were included in the study. PCR-corrected ACPR was 96.3-100 % for ASAQ and 97-100 % for AL across the three study sites. Adverse events were negligible: 0-4.8 % across all sites, for both artemisinin-based combinations. Upon investigation of mutations in the k13 propeller domain, only 9 (1.8 %) mutations were reported, three in each site. All mutant parasites were cleared before day 3. All day 3 positive patients were infected with k13 wild type parasites. The efficacy of AL and ASAQ remains high in Togo, and both drugs are well tolerated. ASAQ and AL would be recommended for the treatment of uncomplicated malaria in Togo.

To demonstrate the feasibility of endoscopic extraperitoneal single site (EESS) inguinal hernia repair and compare it outcomes with the conventional totally extraperitoneal (TEP) technique. TEP inguinal hernia repair is a widely accepted alternative to conventional open technique with several perioperative advantages. Transumbilical laparoendoscopic singlesite surgery (LESS) is an emerging approach and has been reported for a number of surgical procedures with superior aesthetic results but other advantages need to be proven. Thirty-eight uncomplicated inguinal hernias were repaired by EESS approach between January 2010 and January 2011. All procedures were performed through a 25 cm infraumbilical incision using the Alexis wound retractor attached to a surgical glove and three trocars. Body mass index, age, operative time, blood loss, complications, conversion rate, analgesia requirement, hospital stay, return to normal activities and patient satisfaction with aesthetic results were analysed and compared with the last 38 matched-pair group of patients who underwent a conventional TEP inguinal hernia repair by the same surgeon. All procedures were performed successfully with no conversion. In both unilateral and bilateral EESS inguinal repairs, the mean operative time was longer than conventional TEP (55± 20 vs. 40± 15 min, P = 0.049 and 70± 15 vs. 55± 10 min, P = 0.014). Aesthetic result was superior in the EESS group (2.88± 0.43 vs. 2.79± 0.51, P = 0.042). There was no difference between the two approaches regarding blood loss, complications, hospital stay, time until returns to normal activities and analgesic requirement. EESS inguinal hernia repair is safe and effective, with superior cosmetic results in the treatment of uncomplicated inguinal hernias. Other advantages of this new technique still need to be proven.

To compare automated refraction 1 week and 1 month after uncomplicated cataract surgery. In this prospective cohort study, we recruited patients in a 2-month period and included consecutive patients scheduled for bilateral small-incision phacoemulsification cataract surgery. The exclusion criteria were (i) corneal and/or retinal pathology that could lead to automated refraction miscalculation and (ii) surgery complications. Automated refraction was measured 1 week and 1 month after surgery. Ninety-five patients met the in- and exclusion criteria and completed follow-up. The mean refractive shift in spherical equivalent was -0.02 dioptre (D) between 1 week and 1 month after surgery and not statistical significant (p = 0.78, paired t-test). The magnitude of refractive shift in either myopic or hyperopic direction was neither correlated to age, preoperative corneal astigmatism, axial length nor phacoemulsification energy used during surgery (p > 0.05 for all variables, regression analysis). The refractive target was missed with 1.0 D or more in 11 (12%) patients. In this subgroup, the mean refractive shift in spherical equivalent was 0.49 D between 1 week and 1 month after surgery with a trend towards statistical significance (p = 0.07, paired t-test). There was no difference in age, preoperative corneal astigmatism, axial length or phacoemulsification energy used during surgery compared to the remainder of the patients (p > 0.05 for all variables, unpaired t-test). Automated refraction is stabile 1 week after uncomplicated cataract surgery, but there is a trend towards instability, if the refractive target is missed with 1.0 D or more. © 2017 Acta Ophthalmologica Scandinavica Foundation.

This pilot study was undertaken to characterise the pharmacokinetics, pharmacodynamics and potential clinical efficacy of levofloxacin 750 mg once daily for 5 days for treatment of women with acute uncomplicated pyelonephritis. Four women diagnosed with acute pyelonephritis were enrolled. Following pre-therapy specimen collection, an initial oral dose of 750 mg levofloxacin was administered. The mean pharmacokinetic parameters for the first dose were: maximum serum concentration (C(max)) 12.5+/-4.7 mg/L (range 5.6-16.0mg/L) (fC(max) 8.8+/-3.3, where f indicates the levofloxacin free or non-protein-bound fraction), area under the serum concentration-time curve (AUC) 85.4+/-14.1 mgh/L (range 66.2-96.8 mgh/L) (fAUC 59.8+/-9.9) and serum half-life (t(1/2)) 6.7+/-0.5h. Mean urine concentrations were 88.0+/-100mg/L at the 0-3 h collection, 307+/-143 mg/L at 3-6 h, 170+/-107 mg/L at 6-12 h and 85+/-8 mg/L at 12-24 h. Mean levofloxacin serum pharmacodynamics for infecting Escherichia coli were: C(max)/minimum inhibitory concentration (MIC) 323+/-185(fC(max)/MIC 226+/-129); and AUC/MIC 2339+/-830(fAUC/MIC 1647+/-579). Mean urine levofloxacin concentration/MIC ratios were: 900+/-1389 for 0-3 h, 12100+/-4950 for 3-6 h, 5922+/-3912 for 6-12 h and 2233+/-1037 for 12-24 h. Levofloxacin eradicated E. coli from the urine by 3-6 h after the first dose. Levofloxacin 750 mg once daily for 5 days has pharmacodynamics that support further evaluation of this regimen for treatment of women with acute uncomplicated pyelonephritis.

Background There is increasing attention to labor induction and cesarean delivery occurring at 37 0/7 – 38 6/7 weeks’ gestation (early-term) without medical indication. Objective To measure prevalence, change over time, patient characteristics, and infant outcomes associated with early-term nonindicated births. Research Design and Subjects Retrospective analysis using linked hospital discharge and birth certificate data for the 7,296,363 uncomplicated term (>37 0/7 weeks’ gestation) births between 1995-2009 in 3 states. Measures Early-term nonindicated birth is calculated using diagnosis codes and birth certificate records. Secondary outcomes included infant prolonged length of stay and respiratory distress. Results Across uncomplicated term births, the early-term nonindicated birth rate was 3.18%. After adjustment, the risk of nonindicated birth before 39 weeks was 86% higher in 2009 than 1995 (hazard ratio [HR]=1.86 [95% confidence interval (CI), 1.81–1.90]), peaking in 2006 (HR=2.03; P < .001). Factors independently associated with higher odds included maternal age, higher education levels, private health insurance, and delivering at smaller-volume or nonteaching hospitals. Black women had higher risk of nonindicated cesarean birth (HR=1.29 [95% CI, 1.27–1.32]), which was associated with greater odds of prolonged length of stay (adjusted odds ratio [AOR]=1.60 [95% CI, 1.57–1.64]) and infant respiratory distress (AOR= 2.44 [95% CI, 2.37–2.50]) compared with births after 38 6/7 weeks. Early-term nonindicated induction was also associated with comparatively greater odds of prolonged length of stay (AOR=1.20 [95% CI, 1.17–1.23]). Conclusion Nearly 4% of all uncomplicated births to term infants occurred before 39 0/7 weeks' gestation without medical indication. These births were associated with adverse infant outcomes.

Mefloquine-artesunate combination therapy for uncomplicated falciparum malaria is one of the treatments used in African children. Data concerning neurological safety in adults and children treated with mefloquine and artesunate combination therapy is well documented in Asia. Safety data for neurological and neuropsychiatric side effects of mefloquine and artesunate combination therapy in African children are scarce, although WHO recommends this therapy in Africa. A phase IV, open label, single arm study was conducted among African children between 10 and 20 kg with acute uncomplicated falciparum malaria. They were treated over three consecutive days with a paediatric fixed-dose combination of artesunate (50 mg/d) and mefloquine (125 mg/d). Parasitological, clinical and neurological examinations and standardized questions about neuropsychiatric symptoms were carried out on days 0, 4, 7, 28 and 63. The primary objective was to assess the neurological and neuropsychiatric safety of artesunate-mefloquine combination therapy in young children. From December 2007 to March 2009, 220 children with uncomplicated Plasmodium falciparum malaria were treated with artesunate and mefloquine. 213 children were analysed according to study protocol. 50 neurological and neuropsychiatric adverse events occurred in 28 patients. Eleven drug-related neurological and neuropsychiatric adverse events occurred in eight patients. Sleeping disorders were present in 2.3%, neurological disorders in 1.4%, neuropsychiatric disorders in 1% and eating disorders in 0.5% of the patients. Adverse events were of mild to moderate intensity and resolved spontaneously. African children showed a low percentage of self-limited neurological and neuropsychiatric adverse events, confirming studies on neurological safety in Asian children treated with artesunate and mefloquine. Sleeping disorders were most frequently observed.

Oocyte donation (OD) is a specific method of artificial reproductive technology that is accompanied by a higher risk of preeclampsia during pregnancy. The pathophysiological mechanism underlying preeclampsia in OD pregnancies is thought to differ from preeclampsia in autologous pregnancies. As preeclampsia in autologous pregnancies is suggested to be associated with complement activation, we studied C4d deposition, circulating complement components and placental complement regulatory proteins in preeclamptic OD pregnancies. Women with uncomplicated and preeclamptic pregnancies after OD or spontaneous conception were selected. We stained the placentas for C4d, marker for complement activation, measured complement factors C1q, C3 and C4 in maternal sera and quantified the placental mRNA expression of complement regulatory proteins CD46, CD55 and CD59. A significantly (p < 0.03) higher incidence of C4d deposition was observed in placentas from women with preeclampsia compared with uncomplicated pregnancies, both OD and autologous. The level of complement factors in serum did not differ between the groups. Children born in the autologous preeclampsia group were significantly lower in birth weight (p < 10th percentile) compared with the preeclamptic OD group. In addition, the placental mRNA expression level of complement regulatory proteins was significantly lower in uncomplicated and preeclamptic OD compared with the autologous pregnancies. In line with autologous preeclampsia pregnancies, there is excessive activation of complement in preeclamptic OD pregnancies. However, in contrast to autologous pregnancies this is not associated with counterbalancing upregulation of complement regulatory proteins. Furthermore, C4d deposition in OD pregnancies is not related to the severity of preeclampsia, suggesting another trigger or regulatory mechanism of placental C4d deposition in preeclamptic OD pregnancies.

Artemisinin-based combination therapies are recommended as first-line agents for treating uncomplicated Plasmodium falciparum malaria. Ferroquine, a 4-aminoquinolone, is a novel long-acting combination partner for fast-acting drugs like artesunate (AS). We did a small phase 2a, multicenter, open-label, safety-focused dose-ranging randomized study of ferroquine at three African hospitals: two Gabonese and one Kenyan. We recruited adult men with symptomatic uncomplicated P. falciparum monoinfection. Four escalating doses of ferroquine (100, 200, 400, and 600 mg) were assessed in sequence, versus an amodiaquine comparator. After a 2:1 randomization (block size three, equating to N = 12 for each ferroquine dose and N = 6 for each of four amodiaquine comparator groups) patients received daily for three consecutive days, either ferroquine + AS (200 mg/day) or amodiaquine (612 mg/day) + AS (200 mg/day). Safety, electrocardiograms, parasite clearance times, efficacy, and pharmacokinetics were assessed to day 28. Seventy-two patients were randomized. Ferroquine + AS showed generally mild increases (Grade 1 toxicity) in alanine aminotransferase (ALT) levels with a dose trend starting at 400 mg. There were two Grade 2 ALT events: one patient receiving 200 mg (3.8 upper limit of normal [ULN], day 7) and one receiving 600 mg (3.3 ULN, day 14), both without increased bilirubin. One ferroquine 100 mg + AS patient after one dose was withdrawn after developing a QTcF interval prolongation > 60 milliseconds over baseline. Parasitemias in all patients cleared quickly, with no recurrence through day 28. Hepatic, as well as cardiac, profiles should be monitored closely in future trials.

Familial spastic paraplegia (FSP) (MIM No.18260) constitutes a clinically and genetically diverse group of disorders that share the primary feature of progressive, severe, lower extremity spasticity. FSP is classified according to the mode of inheritance and whether progressive spasticity occurs in isolation ({open_quotes}uncomplicated FSP{close_quotes}) or with other neurologic abnormalities ({open_quotes}complicated FSP{close_quotes}), including optic neuropathy, retinopathy, extrapyramidal disturbance, dementia, ataxia, ichthyosis, mental retardation, or deafness. Recently, autosomal dominant, uncomplicated FSP was shown to be genetically heterogeneous and tightly linked to a group of microsatellite markers on chromosome 14q in one large kindred. We examined 126 members of a non-consanguineous North Americanmore » kindred of Irish descent. FSP was diagnosed in 31 living subjects who developed insidiously progressive gait disturbance between ages 12 and 35 years. Using genetic linkage analysis to microsatellite DNA polymorphisms, we showed that the FSP locus on chromosome 14q was exluded from linkage with the disorder in our family. Subsequently, we searched for genetic linkage between the disorder and microsatellite DNA polymorphisms spanning approximately 50% of the genome. We observed significantly positive, two-point maximum lod scores (Z) for markers on chromosome 15q: D15S128 (Z=9.70, {theta}=0.05), D15S165 (Z=3.30, {theta}=0.10), and UT511 (Z=3.86, {theta}=0.10). Our data clearly establishes that one locus for autosomal dominant, uncomplicated FSP is mapped to the pericentric region of chromosome 15q. Identifying genes responsible for chromosome 15q-linked and chromosome 14q-linked FSP will greatly advance our understanding of this condition and hopefully other inherited and degenerative brain and spinal cord disorders that are also characterized by axonal degeneration.« less

The objective of the study was to assess women's preferences for vaginal vs cesarean delivery in 4 contexts: prior cesarean delivery, twins, breech presentation, and absent indication for cesarean. This was a cross-sectional study of pregnant women at 24-40 weeks' gestation. After assessing stated preferences for vaginal or cesarean delivery, we used the standard gamble metric to measure the strength of these preferences and the time tradeoff metric to determine how women value the potential processes and outcomes associated with these 2 delivery approaches. Among the 240 participants, 90.8% had a stated preference for vaginal delivery. Across the 4 contexts, these women indicated that, on average, they would accept a 59-75% chance of an attempted vaginal birth ending in a cesarean delivery before choosing a planned cesarean delivery, indicating strong preferences for spontaneous, uncomplicated vaginal delivery. Variations in preferences for labor processes emerged. Although uncomplicated labor ending in vaginal birth was assigned mean utilities of 0.993 or higher (on a 0-1 scale, with higher scores indicating more preferred outcomes), the need for oxytocin, antibiotics, or operative vaginal delivery resulted in lower mean scores, comparable with those assigned to uncomplicated cesarean delivery. Substantially lower scores (ranging from 0.432 to 0.598) were obtained for scenarios ending in severe maternal or neonatal morbidity. Although most women expressed strong preferences for vaginal delivery, their preferences regarding interventions frequently used to achieve that goal varied. These data underscore the importance of educating patients about the process of labor and delivery to facilitate incorporation of informed patient preferences in shared decision making regarding delivery approach.

The six-minute walk test (6MWT) is a simple, low cost, reliable, and valid method for evaluating the functional capacity of cardiac patients. However, its early use and safety following acute myocardial infarction (AMI) is recent and has been little investigated. To evaluate and to compare the safety and the cardiac behavior of early performance of the 6MWT in patients following uncomplicated AMI up to 4 days or more than 4 days after the event. Following discharge from the Coronary Care Unit, 152 stable asymptomatic patients diagnosed with uncomplicated AMI performed the 6MWT. During the test, in addition to the distance walked, heart rate (HR), blood pressure (BP), and adverse events were also recorded. Electrocardiography was recorded using a Holter monitor in 105 patients. Patients were allocated considering two groups according to the number of days since AMI: Up to 4 Days Group and After 4 Days Group. All patients completed the 6MWT, 66 in the Up to 4 Days Group and 86 in the After 4 Days Group. The walking distance was similar in both groups (85% of the predicted value), as well as the physiological responses (increase in systolic BP and HR), reaching 63% (median) of maximum HR. Only 3.9% of patients had major complications (angina, drop in BP, or ventricular tachycardia), with no difference between the groups. None of the complications regarded as severe led to truly significant complications or death. The 6MWT was proven to be safe and feasible for early functional evaluation following uncomplicated AMI.

Objectives This study is designed to investigate the effects of anti-hypertensive monotherapy [either calcium channel blocker (CCB) or angiotensin receptor blocker (ARB)] on pulsatile hemodynamic parameters in patients with uncomplicated hypertension. Methods This is a longitudinal observational study. For simplicity, we included patients with uncomplicated hypertension who receivedmono anti-hypertensive therapy with ARB or CCB. Hemodynamic parameters including central arterial pressure (CAP), aortic characteristic impedance (Zc), augmentation index (AI), brachial-ankle pulse wave velocity (baPWV), heart-ankle pulse wave velocity (haPWV), cardiac ultrasonographic parameters and ventriculo-arterial (VA) coupling were measured before, 1 month and 3 months after treatment. Results A total of 74 subjects were included in our study for analysis from 2007-2008. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and central systolic arterial pressure (CSAP) were significantly reduced 1 and 3 months after initiation of therapy. Among the pulsatile hemodynamic parameters, only the baPWV was significantly reduced (from1537.78 ± 200.63 cm/s to 1460.06 ± 186.09 cm/s to 1456.53 ± 196.03 cm/s, p for trend = 0.016). The haPWV only decreased with borderline significance (from 1015.38 ± 124.26 cm/s to 978.88 ± 126.55 cm/s to 967.99 ± 103.37 cm/s, p for trend = 0.041). The other pulsatile hemodynamic parameters remained unchanged before and after therapy. Subgroup analysis (age above or below52 years) showed that the baPWVwas significantly reduced only in the younger group. Conclusions Among the pulsatile hemodynamic parameters, only the baPWV was effectively reduced by either CCB or ARB. The improvement of PWV was more evident in younger subjects. PMID:27122681

Currently, ureterorenoscopic (URS) stone fragmentation and removal is the treatment of choice for managing ureteral stones, especially mid and distal ones and is advocated as initial management of ureteric stones. The aim of this work was to evaluate the symptoms, necessity, potential benefits and adverse effects of ureteral stent placement after uncomplicated ureteroscopic lithotripsy. This retrospective-prospective study evaluated a total of 125 patients who had underwent ureteroscopic lithotripsy (URSL). The patients were divided into two groups: stented (59 patients) and unstented (controls, 66 patients). The outcomes measured and compared between the two groups included: stone free rate, postoperative patient pain validated by scale, lower urinary tract symptoms (LUTS), the need for unplanned hospital care, stent related complications, and functional recovery in the form return to normal physical activities. A successful outcome, defined as being stonefree after 12 weeks, was achieved in all 125 (100%) patients. The stone-free rate showed no significant differences between the two groups. LUTS was frequent complaint in the stented group, with statistically significant difference in the domain of frequency/urgency (p = 0.0314). There was a statistically significant difference between the groups in the mean operative time and mean hospitalization time, mean pain visual analog scale (VAS) score and in the use of nonnarcotic analgesic. On the day of the surgery and until postoperative day 3 (POD 3) and postoperative day 5 (POD 5), the pain score was much higher among stented patients than among the controls (p = 0.0001) and non-narcotic analgesic use (p = 0.001) was frequently required in the stented group. Routine placement of ureteral stent after URSL is not mandatory and may be associated with stent side effects. Uncomplicated URSL is safe without stent placement after the treatment.

Practice guidelines recommend the shortest duration of antimicrobial therapy appropriate to treat uncomplicated pneumonia be prescribed to reduce the emergence of resistant pathogens. A national evaluation was conducted to assess the duration of therapy for pneumonia. Retrospective medication utilization evaluation. Thirty Veterans Affairs medical centers. Inpatients discharged with a diagnosis of pneumonia. A manual review of electronic medical records of inpatients discharged with uncomplicated community-acquired pneumonia (CAP) or healthcare-associated pneumonia (HCAP) was conducted. Appropriate CAP therapy duration was defined as at least 5 days, and up to 3 additional days beginning the first day the patient achieved clinical stability criteria; the appropriate HCAP therapy duration was defined as 8 days. The duration of antimicrobial therapy for intravenous (IV) and oral (PO) inpatient administration, PO therapy dispensed upon discharge, Clostridium difficile infection (CDI), hospital readmission, and death rates were measured. Of 3881 pneumonia admissions, 1739 met inclusion criteria (CAP [n = 1195]; HCAP [n = 544]). Overall, 13.9% of patients (CAP [6.9%], HCAP [29.0%]) received therapy duration consistent with guideline recommendations. The median (interquartile range) days of therapy were 4 days (3-6 days), 1 day (0-3 days), and 6 days (4-8 days) for inpatient IV, inpatient PO, and outpatient PO antimicrobials, respectively. CDI was rare but more common in patients who received therapy duration consistent with guidelines. Therapy duration was not associated with the readmission or mortality rate. Antimicrobials were commonly prescribed for a longer duration than guidelines recommend. The majority of excessive therapy was completed upon discharge, identifying the need for strategies to curtail unnecessary use postdischarge.

There were two aims of the present study: (1) to evaluate changes of superoxide dismutase (SOD) activity and total antioxidative status measured as the ferric reducing ability of plasma (FRAP) concentration in saliva of pregnant women during the first, second, and third trimesters of singleton uncomplicated pregnancy and (2) to assess possible relations among SOD, FRAP, and intake of macronutrients and micronutrients in daily nutritional rations (DNRs) during pregnancy. Forty pregnant women aged 27.1+/-5.4 yr (examined group) and 40 healthy women (the control group) were recruited for this study. The relationship between FRAP and SOD in saliva and the intake of macronutrients (proteins, carbohydrates, total fat, saturated fatty acid, monounsaturated fatty acids, polyunsaturated fatty acids), minerals (Na, K, Ca, P, Mg, Fe, Zn, Cu, Mn), and vitamins (A, C, E, B1, B2, B6, PP) in DNR was evaluated by clustering analysis with Ward's grouping method. During pregnancy, FRAP and SOD values were lower than in the controls, but only for FRAP were the differences statistically significant (p < 0.001). For the whole pregnancy period, cluster analysis identified two major clusters for which the differentiating variables were SOD and retinoids intake, but different patterns for each trimester of pregnancy were revealed. The following were concluded: (1) FRAP values were the lowest in the second trimester. It suggests that in this trimester of uncomplicated pregnancy, women might be not fully adapted to increased demands for antioxidative mechanisms. (2) Cluster analysis showed that there were no statistical relationships between the intake of micronutrients and macronutrients in DNRs and the SOD or FRAP level in the saliva of pregnant women.

Umbilical hernia is a common pathology and surgical repair is advised to prevent complications in symptomatic patients. However, risk factors that predict such advert events are unknown. The aim of the study was to determine whether morphological characteristics are associated with the occurrence of complications. Retrospective review of adult patients with elective and emergent umbilical hernia repair operated from January 2004 to December 2013. The size of the hernia and the size of the neck were measured based on operative reports, ultrasound, CT or MRI images. The Hernia-Neck-Ratio (HNR) was then calculated as novel risk indicator. 106 patients underwent umbilical hernia repair (70 for uncomplicated and 36 for complicated hernia) as single procedure. The median size of the hernia sac was statistically significantly smaller in the uncomplicated group (30 mm, interquartile range (IQR) 20-49 vs. 50 mm, IQR 40-71, p = 0.037). The median size of the neck was not different between both groups (15 mm, IQR 11-29 vs. 16 mm, IQR 12-21, p = 0.44). The median HNR was smaller in the uncomplicated group (1.76, IQR 1.45-2.18 vs. 3.33, IQR 2.97-3.91, p = 0.00026). Based on ROC curve analysis (area under the curve: 0.9038), a cut-off value of 2.5 was associated with 91 % sensitivity and 84 % specificity. A novel predictive factor for complications related to umbilical hernia is proposed. The Hernia-Neck Ratio can easily be calculated. These results suggest that umbilical hernia with HNR >2.5 should be operated, irrespective of the presence of symptoms.

Purpose - The purpose of this paper is to investigate the feasibility of telephone follow-up (TFU) after uncomplicated cataract surgery in low-risk patients and patient satisfaction with this alternative clinical pathway. Design/methodology/approach - Prospective, non-randomised cohort study. A ten-point subjective ophthalmic assessment questionnaire and a six-point patient satisfaction questionnaire were administered to patients following routine cataract surgery at two to three weeks post-procedure. All patients were offered a further clinic review if required. Exclusion criteria comprised ophthalmic co-morbidities, hearing/language impairment and high risk of post-operative complications. Patient notes were retrospectively reviewed over the study period to ensure no additional emergency attendances took place. Findings - Over three months, 50 eyes of 50 patients (mean age: 80; age range 60-91; 66 per cent second eye surgery) underwent uncomplicated phacoemulsification surgery received a TFU at 12-24 days (mean: 16 days) post-operatively. Subjective visual acuity was graded as good by 92 per cent of patients; 72 per cent patients reported no pain and 20 per cent reported mild occasional grittiness. Patient satisfaction was graded 8.9 out of 10; 81.6 per cent defined TFU as convenient and 75.5 per cent of patients preferred TFU to routine outpatient review. No additional visits were required. Research limitations/implications - Non-randomised with no control group; small sample size. One patient was unable to be contacted. Practical implications - Post-operative TFU can be suitably targeted to low-risk patients following uncomplicated cataract surgery. This study demonstrated a high patient satisfaction. A larger, randomised study is in progress to assess this further. Originality/value - This is the first study reporting TFU results and patient satisfaction to the usual alternative two-week outpatient review.

The simian parasite Plasmodium knowlesi causes severe human malaria; the optimal treatment remains unknown. We describe the clinical features, disease spectrum, and response to antimalarial chemotherapy, including artemether-lumefantrine and artesunate, in patients with P. knowlesi malaria diagnosed by PCR during December 2007–November 2009 at a tertiary care hospital in Sabah, Malaysia. Fifty-six patients had PCR-confirmed P. knowlesi monoinfection and clinical records available for review. Twenty-two (39%) had severe malaria; of these, 6 (27%) died. Thirteen (59%) had respiratory distress; 12 (55%), acute renal failure; and 12, shock. None experienced coma. Patients with uncomplicated disease received chloroquine, quinine, or artemether-lumefantrine, and those with severe disease received intravenous quinine or artesunate. Parasite clearance times were 1–2 days shorter with either artemether-lumefantrine or artesunate treatment. P. knowlesi is a major cause of severe and fatal malaria in Sabah. Artemisinin derivatives rapidly clear parasitemia and are efficacious in treating uncomplicated and severe knowlesi malaria. PMID:21762579

The purpose of the study was to ascertain the therapeutic efficacy of different treatments for uncomplicated falciparum malaria in the hospitals in Sagaing, northern and eastern Shan, to facilitate updating the existing national antimalarial drug policy. The proposed 14-day trial for monitoring the efficacy of treatments of uncomplicated falciparum malaria is an efficient method for identifying treatment failure patterns at the intermediate level (township hospital) in the Union of Myanmar. Minimal clinical and parasitological data for days 0-14 were required to classify treatment failure and success. Clinical and parasitiological responses on day 3 and days 4-14 were used as clear examples of early and late treatment failure, respectively. Mefloquine is five times more likely to be effective than chloroquine and sulfadoxine pyrimethamine (S-P), whereas chloroquine and S-P treatments have nearly identical failure patterns. The alarming frequency of clinical and parasitological failure (failure rate > 50%) following chloroquine treatment was reported in Sagaing and following S-P treatment in Sagaing and eastern Shan.

Severe malaria caused by Plasmodium vivax is no longer considered rare. To describe its clinical features, we performed a retrospective case control study in the subregion of Luciano Castillo Colonna, Piura, Peru, an area with nearly exclusive vivax malaria transmission. Severe cases and the subset of critically ill cases were compared with a random set of uncomplicated malaria cases (1:4). Between 2008 and 2009, 6,502 malaria cases were reported, including 106 hospitalized cases, 81 of which fit the World Health Organization definition for severe malaria. Of these 81 individuals, 28 individuals were critically ill (0.4%, 95% confidence interval = 0.2–0.6%) with severe anemia (57%), shock (25%), lung injury (21%), acute renal failure (14%), or cerebral malaria (11%). Two potentially malaria-related deaths occurred. Compared with uncomplicated cases, individuals critically ill were older (38 versus 26 years old, P < 0.001), but similar in other regards. Severe vivax malaria monoinfection with critical illness is more common than previously thought. PMID:24752683

Previous studies have investigated the utility of inflammation markers as predictors of preterm birth, but none have compared trends in levels between uncomplicated and preterm pregnancy. We explored longitudinal changes in plasma cytokines, including IL-1β, IL-6, IL-10, and TNF-α, as well as C-reactive protein in pregnant women from a nested case-control study. IL-6 was associated with increased odds of spontaneous preterm birth, defined by presentation of spontaneous preterm labor and/or preterm premature rupture of the membranes. Associations were strongest later in pregnancy. IL-10 was associated with increased odds of placentally mediated preterm birth, defined by presentation with preeclampsia or intrauterine growth restriction, and odds ratios were also highest near the end of pregnancy. Maternal inflammation markers were associated with increased risk of preterm birth, and relationships differed by etiology of preterm delivery and gestational age at sample collection. © 2014 John Wiley & Sons A/S.

Is curettage needed for uncomplicated incomplete spontaneous abortion?

PubMed

Ballagh, S A; Harris, H A; Demasio, K

1998-11-01

Spontaneous abortion occurs in 15% to 20% of all human pregnancies. Since the late 1800s, the management of incomplete spontaneous abortion has focused on using curettage to empty the uterus as quickly as possible. This practice began to reduce blood loss and infection and has been unquestioned for 4 decades. In today's medical climate, few spontaneous abortions are the resuslt of illegal manipulation, given the availability of legal pregnancy termination. Antibiotics and transfusions are available, should complications arise in conservatively managed cases. Two prospective randomized trials suggest that conservative management may be advantageous for women who have stable vital signs without evidence of infection. They will have fewer perforations and, possibly, fewer infections and uterine synechiae with expectant or medical management. Larger trials should be undertaken to critically assess surgical evacuation compared to medical management, factoring in the psychologic impact of treatment. We believe that medical management will prove to be the most appropriate treatment for uncomplicated spontaneous incomplete abortion in the 21st century.

Patient management following uncomplicated elective gastrointestinal operations.

D'Costa, H; Taylor, E W

The management of patients after uncomplicated elective gastrointestinal operations is frequently left to junior members of the surgical team once they have learnt their seniors' regimens. The use of nasogastric (N/G) tubes, the volume of intravenous (IV) fluid replacement and the reintroduction of oral fluids and solids are topics not generally covered in the surgical textbooks and so are learnt in hospital. A postal survey of all consultant general surgeons in Scotland was conducted to assess the variations in management of patients after cholecystectomy, right haemicolectomy and sigmoid colectomy. A completed questionnaire was received from 111 (81%) of the surgeons circulated. As might be expected, patient management varied widely from surgeon to surgeon, and from unit to unit. There would appear to be a need for prospective studies in this area of patient management. This may indicate that the use of N/G tubes could be further reduced and that oral fluids and solids could be reintroduced sooner after operation with improved patient comfort and reduced hospital stay, yet without detriment to patient care.

Posttransplantation measurement of soluble CD30 (sCD30) may be useful for identifying kidney graft recipients at risk of impending graft rejection in the early posttransplantation period. We measured plasma sCD30 levels and evaluated the levels in relation to the diagnosis of rejection. Receiver operating characteristic curves demonstrated that on posttransplantation days 3 to 5, sCD30 allowed a differentiation of recipients who subsequently developed acute allograft rejection (n=25) from recipients with an uncomplicated course (n=20, P<0.0001) (area under the receiver operating characteristic curve 0.96, specificity 100%, sensitivity 88%) and recipients with acute tubular necrosis in the absence of rejection (n=11, P=0.001) (area under the receiver operating characteristic curve 0.85, specificity 91%, sensitivity 72%). sCD30 measured on posttransplantation days 3 to 5 offers a noninvasive means for differentiating patients with impending acute allograft rejection from patients with an uncomplicated course or with acute tubular necrosis.

The relation between coronary heart disease and disability was examined in 2,576 community-dwelling women and men ages 55-88 years. These Framingham Study participants were originally recruited in 1948-51 for an examination of cardiovascular disease. Twenty-seven years later, remaining members of the cohort were interviewed to ascertain physical abilities, and a score on a disability scale was assigned. Multivariate logistic analyses examined disability in relation to uncomplicated angina pectoris (AP), complicated AP, and coronary heart disease other than AP, controlling for possible confounders. In younger and older women and men, uncomplicated and complicated AP were associated with disability. Coronary heart disease other than AP was associated with disability only in the younger men. Congestive heart failure predicted disability only in the women. These results suggest that onset of AP should be recognized as a critical point in the development of disability and that AP is a better predictor of disability than is myocardial infarction or coronary insufficiency.

This study assessed the safety of the new World Health Organization (WHO) recommendation of adding a single low-dose of primaquine (PQ) to standard artemisinin-based combination therapy (ACT), regardless of individual glucose-6-phosphate dehydrogenase (G6PD) status, for treatment of acute uncomplicated Plasmodium falciparum malaria in Tanzania. Men and non-pregnant, non-lactating women aged ≥1 year with uncomplicated P. falciparum malaria were enrolled and randomized to either standard artemether-lumefantrine (AL) regimen alone or with a 0.25 mg/kg single-dose of PQ. PQ was administered concomitantly with the first AL dose. All drug doses were supervised. Safety was evaluated between days 0 and 28. G6PD status was assessed using rapid test (CareStart™) and molecular genotyping. The primary endpoint was mean percentage relative reduction in haemoglobin (Hb) concentration (g/dL) between days 0 and 7 by genotypic G6PD status and treatment arm. Overall, 220 patients, 110 per treatment arm, were enrolled, of whom 33/217 (15.2 %) were phenotypically G6PD deficient, whereas 15/110 (13.6 %) were genotypically hemizygous males, 5/110 (4.5 %) homozygous females and 22/110 (20 %) heterozygous females. Compared to genotypically G6PD wild-type/normal [6.8, 95 % confidence interval (CI) 4.67-8.96], only heterozygous patients in AL arm had significant reduction in day-7 mean relative Hb concentration (14.3, 95 % CI 7.02-21.55, p=0.045), however, none fulfilled the pre-defined haemolytic threshold value of ≥25 % Hb reduction. After adjustment for baseline parasitaemia, Hb, age and sex the mean relative Hb reduction was not statistically significant in both heterozygous and hemizygous/homozygous patients in both arms. A majority of the adverse events (AEs) were mild and unrelated to the study drugs. However, six (4.4 %) episodes, three per treatment arm, of acute haemolytic anaemia occurred between days 0 and 7. Three occurred in phenotypically G6PD deficient patients, two in AL and one in AL + PQ arm, but none in genotypically hemizygous/homozygous patients. All patients with acute haemolytic anaemia recovered without medical intervention. The findings support that the WHO recommendation of adding a single low-dose of PQ to standard AL regimen is safe for the treatment of acute uncomplicated P. falciparum malaria regardless of G6PD status in Tanzania. Trial registration number NCT02090036.

Plasmodium falciparum clearance with artemisinin-based combination therapy (ACT) in patients with glucose-6-phosphate dehydrogenase deficiency in Mali

PubMed Central

2010-01-01

Background Artemisinin-based combination therapy (ACT) is currently the most effective medicine for the treatment of uncomplicated malaria. Artemisinin has previously been shown to increase the clearance of Plasmodium falciparum in malaria patients with haemoglobin E trait, but it did not increase parasite inhibition in an in vitro study using haemoglobin AS erythrocytes. The current study describes the efficacy of artemisinin derivatives on P. falciparum clearance in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD), a haemoglobin enzyme deficiency, not yet studied in the same context, but nonetheless is a common in malaria endemic areas, associated with host protection against uncomplicated and severe malaria. The impact of G6PD deficiency on parasite clearance with ACT treatment was compared between G6PD-deficient patients and G6PD-normal group. Methods Blood samples from children and adults participants (1 to 70 years old) with uncomplicated P. falciparum malaria residing in Kambila, Mali were analysed. Study participants were randomly assigned to receive either artemether-lumefantrine (Coartem®) or artesunate plus mefloquine (Artequin™). A restriction-fragment length polymorphism analysis of PCR-amplified DNA samples was used to identify the (A-) allele of the gene mutation responsible for G6PD deficiency (G6PD*A-). 470 blood samples were thus analysed and of these, DNA was extracted from 315 samples using the QIAamp kit for PCR to identify the G6PD*A- gene. Results The DNA amplified from 315 samples using PCR showed that G6PD*A- deficiency was present in 56 participants (17.8%). The distribution of the specific deficiency was 1%, 7% and, 9.8% respectively for homozygous, hemizygous, and heterozygous genotypes. Before treatment, the median parasitaemia and other baseline characteristics (mean haemoglobin, sex and age groups) between G6PD deficiency (hemizygous, heterozygous, and homozygous) and G6PD-normal participants were comparable (p > 0.05). After treatment, parasite clearance did not change significantly whether the participants were G6PD deficient or G6PD normal on day 1 (OR = 1.3; CI = 0.70-2.47; p > 0.05) and on day 2 (OR = 0.859; CI = 0.097-7.61; p > 0.05). Conclusions The presence of G6PD deficiency does not appear to significantly influence the clearance of P. falciparum in the treatment of uncomplicated malaria using ACT. PMID:21092137

To investigate the changes of ambulatory electrocardiography and peripheral blood SOD, MDA and Na+-K+-ATP enzymes in patients of acute myocardial infarction (AMI) complicated with arrhythmia. From January 2012 to March 2015, 135 cases AMI complicated with arrhythmia in our hospital were divided into 2 groups: 70 cases in the AMI uncomplicated with arrhythmia and 65 cases in the AMI complicated with arrhythmia. 62 cases volunteers accepted physical examination in our hospital in the same period were collected as the control group. 24 hour-electrocardiogram detected by ambulatory electrocardiogram (AECG), SOD and MDA in peripheral blood detected by diagnostic reagent kit and Na+-K+-ATP enzymes in peripheral blood detected by malachite green Kit Method phosphate determination method were collected. ROC curve was used to evaluate the prognostic value of SOD, MDA and Na+-K+-ATP enzymes in AMI patients. Compared with the control group, the patients had unusual ambulatory electrocardiography had increased (P <0.05), peripheral blood SOD and Na+-K+-ATP enzymes had decreased, peripheral blood MDA had increased in 2 AMI groups (P <0.05). Compared with AMI uncomplicated with arrhythmia group, the patients had unusual ambulatory electrocardiography had increased (P <0.05), peripheral blood SOD and Na+-K+-ATP enzymes had decreased, peripheral blood MDA had increased in AMI complicated with arrhythmia group (P <0.05). Among 135 cases AMI patients, 120 (88.9%) survived and 15 (11.1%) died, of whom 11 cases were AMI complicated with arrhythmia group, 4 cases were AMI uncomplicated with arrhythmia group. Compared with the AMI uncomplicated with arrhythmia group, the dead patients were more in the AMI complicated with arrhythmia group (c2 = 4.287, P = 0.038). Compared with the survival group, the SOD and Na+-K+-ATP enzymes were significantly lower (P <0.05) and MDA significantly higher (P <0.05) in the death group. The area under the ROC curve of SOD, MDA and Na+-K+-ATP enzymes were 0.958, 0.954 and 0.993 respectively, and the cut-off values were 30.66 ng/ml, 576.70 nmol/ml and 57.42 nmol/mgh, respectively. Ambulatory electrocardiography has a close relationship with the peripheral blood SOD, MDA and Na+-K+-ATP enzymes in AMI patients complicated with arrhythmia, which might predict AMI condition.

Assessment of the therapeutic efficacy of artemether-lumefantrine in the treatment of uncomplicated Plasmodium falciparum malaria in northern KwaZulu-Natal: an observational cohort study

PubMed Central

2012-01-01

Background Recent malaria epidemics in KwaZulu-Natal indicate that effective anti-malarial therapy is essential for malaria control. Although artemether-lumefantrine has been used as first-line treatment for uncomplicated Plasmodium falciparum malaria in northern KwaZulu-Natal since 2001, its efficacy has not been assessed since 2002. The objectives of this study were to quantify the proportion of patients treated for uncomplicated P. falciparum malaria with artemether-lumefantrine who failed treatment after 28 days, and to determine the prevalence of molecular markers associated with artemether-lumefantrine and chloroquine resistance. Methods An observational cohort of 49 symptomatic patients, diagnosed with uncomplicated P. falciparum malaria by rapid diagnostic test, had blood taken for malaria blood films and P. falciparum DNA polymerase chain reaction (PCR). Following diagnosis, patients were treated with artemether-lumefantrine (Coartem®) and invited to return to the health facility after 28 days for repeat blood film and PCR. All PCR P. falciparum positive samples were analysed for molecular markers of lumefantrine and chloroquine resistance. Results Of 49 patients recruited on the basis of a positive rapid diagnostic test, only 16 were confirmed to have P. falciparum by PCR. At follow-up, 14 were PCR-negative for malaria, one was lost to follow-up and one blood specimen had insufficient blood for a PCR analysis. All 16 with PCR-confirmed malaria carried a single copy of the multi-drug resistant (mdr1) gene, and the wild type asparagine allele mdr1 codon 86 (mdr1 86N). Ten of the 16 samples carried the wild type haplotype (CVMNK) at codons 72-76 of the chloroquine resistance transporter gene (pfcrt); three samples carried the resistant CVIET allele; one carried both the resistant and wild type, and in two samples the allele could not be analysed. Conclusions The absence of mdr1 gene copy number variation detected in this study suggests lumefantrine resistance has yet to emerge in KwaZulu-Natal. In addition, data from this investigation implies the possible re-emergence of chloroquine-sensitive parasites. Results from this study must be viewed with caution, given the extremely small sample size. A larger study is needed to accurately determine therapeutic efficacy of artemether-lumefantrine and resistance marker prevalence. The high proportion of rapid diagnostic test false-positive results requires further investigation. PMID:23272998

Chronic urticaria: aetiology, management and current and future treatment options.

PubMed

Kozel, Martina M A; Sabroe, Ruth A

2004-01-01

Chronic urticaria is a common condition that can be very disabling when severe. A cause for chronic idiopathic urticaria (CIU) is only infrequently identified. Potential causes include reactions to food and drugs, infections (rarely) and, apart from an increased incidence of thyroid disease, uncomplicated urticaria is not usually associated with underlying systemic disease or malignancy. About one-third of patients with CIU have circulating functional autoantibodies against the high affinity IgE receptor or against IgE, although it is not known why such antibodies are produced, or how the presence of such antibodies alters the course of the disease or response to treatment. There are only a few publications relating to childhood urticaria, but it is probably similar to the adult form, except that adult urticaria is more common. The diagnosis is based on patient history and it is vital to spend time documenting this in detail. Extensive laboratory tests are not required in the vast majority of patients. Chronic urticaria resolves spontaneously in 30-55% of patients within 5 years, but it can persist for many years. Treatment is aimed firstly at avoiding underlying causative or exacerbating factors. Histamine H1 receptor antagonists remain the mainstay of oral treatment for all forms of urticaria. The newer low-sedating antihistamines desloratadine, fexofenadine, levocetirizine and mizolastine should be tried first. Sedating antihistamines have more adverse effects but are useful if symptoms are causing sleep disturbance. Low-dose dopexin is effective and especially suitable for patients with associated depression. There is controversy as to whether the addition of an histamine H2 receptor antagonist or a leukotriene antagonist is helpful. For CIU, second-line agents include ciclosporin (cyclosporine) [which is effective in approximately 75% of patients], short courses of oral corticosteroids, intravenous immunoglobulins and plasmapheresis, although the last two were found to be beneficial in small trials only. Treatments for CIU with only limited or anecdotal supportive evidence include sulphasalazine, methotrexate, stanazol, rofecoxib and cyclophosphamide. The efficacy of photo(chemo)therapy is controversial. Physical urticarias may respond to H1 receptor antagonists, although in delayed pressure urticaria, and cold, solar and aquagenic urticaria, the response may be disappointing. Second-line agents for physical urticarias vary depending on the urticaria and most have limited supportive evidence. The potential for spontaneous resolution, the variation in the disease activity and the unpredictable nature of the disease makes the efficacy of treatments difficult to assess.

Hidden costs associated with the universal application of risk management in maternity care.

PubMed

McIntyre, Meredith J; Chapman, Ysanne; Francis, Karen

2011-05-01

This paper presents a critical analysis of risk management in maternity care and the hidden costs associated with the practice in healthy women. Issues of quality and safety are driving an increased emphasis by health services on risk management in maternity care. Medical risk in pregnancy is known to benefit 15% or less of all pregnancies. Risk management applied to the remaining 85% of healthy women results in the management of risk in the absence of risk. The health cost to mothers and babies and the economic burden on the overall health system of serious morbidity has been omitted from calculations comparing costs of uncomplicated caesarean birth and uncomplicated vaginal birth. The understanding that elective caesarean birth is cost-neutral when compared to a normal vaginal birth has misled practitioners and contributed to over use of the practice. For the purpose of informing the direction of maternity service policy it is necessary to expose the effect the overuse of medical intervention has on the overall capacity of the healthcare system to absorb the increasing demand for operating theatre resources in the absence of clinical need.

A prospective, randomised trial of prophylactic antibiotics versus bag extraction in the prophylaxis of wound infection in laparoscopic cholecystectomy.

PubMed

Harling, R; Moorjani, N; Perry, C; MacGowan, A P; Thompson, M H

2000-11-01

Septic complications are rare following laparoscopic cholecystectomy if prophylactic antibiotics are given, as demonstrated in previous studies. Antibiotic treatment may be unnecessary and, therefore, undesirable, so we compared two forms of prophylaxis: a cephalosporin antibiotic and bag extraction of the dissected gallbladder. A total of 76 patients undergoing laparoscopic cholecystectomy were randomised to either receive an antibiotic or to have their gallbladder removed from the abdomen in a plastic bag. Complicated cases were excluded. There was a total of 6 wound infections (7.9%), 3 in each of the study groups. All these were associated with skin commensals. There were no other septic complications. Bacteriological studies grouped the organisms isolated from the bile and the wound as potential pathogens and likely commensals. A total of 10 potential pathogens were isolated, 9 of which were found in the group receiving antibiotics. We conclude that septic sequelae of uncomplicated laparoscopic cholecystectomy are uncommon, but clearly not entirely prevented by antibiotic or mechanical prophylaxis. Prophylactic antibiotics may not be required in uncomplicated laparoscopic cholecystectomy. Further study is warranted.

Objective: To introduce new corneal high-speed, ultra–high-resolution optical coherence tomography (hsUHR-OCT) technology that improves the evaluation of complicated and uncomplicated cataract, corneal, and refractive surgical procedures. Design: This case series included a control subject and 9 eyes of 8 patients who had undergone phacoemulsification, Descemet membrane stripping endokeratoplasty, corneal implantation for keratoconus, and complicated and uncomplicated laser in situ keratomileusis. These eyes underwent imaging using a prototype ophthalmic hsUHR-OCT system. All the scans were compared with conventional slitlamp biomicroscopy. Results: Cross-sectional hsUHR-OCT imaging allowed in vivo differentiation of corneal layers and existing pathologic abnormalities at ultrahigh axial image resolution. These images illustrate the various incisional and refractive interfaces created with corneal procedures. Conclusions: The magnified view of the cornea using hsUHR-OCT is helpful in conceptualizing and understanding basic and complicated clinical pathologic features; hsUHR-OCT has the potential to become a powerful, noninvasive clinical corneal imaging modality that can enhance surgical management.

Korting, H C; Abeck, D

1989-01-01

The highest minimum inhibitory concentrations of ceftriaxone and cefotaxime in 89 analysed Neisseria gonorrhoeae isolates amounted to 0.008 and 0.031 micrograms/ml, respectively. In a randomized controlled trial the single intramuscular injection of ceftriaxone 250 mg and cefotaxime 500 mg cured bacteriologically 35 out of 35, and 29 out of 30 patients, respectively, with uncomplicated gonorrhoea. Facing the different phenotypes of the isolates grown before and after therapy in the case of the non-cured patient within the cefotaxime treatment group, reinfection rather than failure has to be presumed. Postgonococcal urethritis occurred about as often in both groups, the percentage amounting to 24.2 and 28.6%, respectively. If side effects were noted at all, they were considered minor: 4 patients belonging to the first and 3 belonging to the second treatment group complained temporarily about pain at the injection site. Due to the data presented here, ceftriaxone and cefotaxime appear equally effective and safe when used in the dose generally preferred, irrespective of differences in in vitro activity and pharmacokinetic behaviour.

Plasmodium falciparum resistance to artemisinins by delayed parasite clearance is present in Southeast Asia. Scant data on parasite clearance after artemisinins are available from Africa, where transmission is high, burden is greatest, and artemisinin use is being scaled up. Children 1–10 years of age with uncomplicated malaria were treated with 7 days of artesunate and followed for 28 days. Blood smears were done every 8 hours until negative by light microscopy. Results were compared with a similar study conducted in the same village in 2002–2004. The polymerase chain reaction-corrected cure rate was 100%, identical to 2002–2004. By 24 hours after treatment initiation, 37.0% of participants had cleared parasitemia, compared with 31.9% in 2002–2004 (P = 0.5). The median parasite clearance time was 32 hours. Only one participant still had parasites at 48 hours and no participant presented parasitemia at 72 hours. Artesunate was highly efficacious, with no evidence of delayed parasite clearance. We provide baseline surveillance data for the emergence or dissemination of P. falciparum resistance in sub-Saharan Africa. PMID:22764287

2010-09-01

Bacterial urinary tract infections (UTIs) are amongst the most common infectious diseases. Therefore, any improvement in UTI management will have a high impact on the quality of life of the individual patient and the entire healthcare system. A dramatic, clinically significant increase in the antimicrobial resistance of uropathogens over the past 5 - 10 years calls for new concepts in the treatment of UTIs. This article focuses on uncomplicated and complicated UTIs, and discusses antimicrobial resistance trends and antibacterial strategies. A literature search was undertaken concerning treatment studies in UTI from 1998 on. Emerging drugs for the treatment of UTI were mainly selected using the Investigational Drugs Database. The aim of this review is to highlight new and emerging drugs in the antibacterial treatment of uncomplicated and complicated UTIs. This article discusses current and future aspects for recommending antibacterials for the treatment of UTIs. Resistance rates of uropathogens are also significantly increasing. Emerging antimicrobial substances are not always investigated for their suitability in the treatment of UTIs. Especially, substances active against multiresistant Gram-negative pathogens will rarely be developed in the coming years.

Urinary tract infection (UTI) is one of the most common conditions during pregnancy. The aim of this study was to assess the prevalence of germs and the antimicrobial susceptibility profile in urine culture isolates from pregnant patients treated at a tertiary maternity hospital in Porto Alegre, Brazil. A cross-sectional, retrospective and descriptive study was carried out at Hospital Fêmina, a leading institution in prenatal, birth and postnatal healthcare in the city of Porto Alegre, Brazil. A total of 482 microbial community results were analyzed out of 1,558 positive urine cultures of pregnant women in all gestational ages treated at Fêmina Hospital between January 2007 and July 2013. The susceptibility pattern presented in this research shows that the choice for UTI treatment during pregnancy should be nitrofurantoin (for uncomplicated infections) or second-generation cephalosporins such as cefuroxime (for uncomplicated and complicated infections), over ampicillin, first-generation cephalosporins and sulfamethoxazole/trimethoprim. Empirical treatment for UTI in pregnancy should be started according to the susceptibility patterns described in the literature and re-analyzed after the results of the urine culture.

Left heart pacing lead implantation using subxiphoid videopericardioscopy.

Zenati, Marco A; Bonanomi, Gianluca; Chin, Albert K; Schwartzman, David

2003-09-01

Recent clinical data support the utility of left heart pacing. The transvenous approach for left heart pacing lead implantation is imperfect. A direct epicardial approach may have advantages, but heretofore its utility has been limited because of the requirement for thoracotomy. We sought to examine the feasibility of a method for epicardial lead implantation that did not require thoracotomy. In five large swine, percutaneous access to the epicardium was achieved with subxiphoid videopericardioscopy, using a device that marries endoscopy with a port through which pacing leads could be introduced. In each animal, standard, active fixation pacing leads were implanted onto the left atrium and ventricle. The atrial lead was implanted at the base of the appendage. The ventricular lead was implanted on the anterior, lateral, and inferior walls. Continuous direct visualization of the epicardium provided guidance for lead localization and fixation, including avoidance of complications such as trauma to epicardial coronary vessels. Capture thresholds were uniformly low. Postmortem examination demonstrated anatomically accurate, uncomplicated lead fixation. Using subxiphoid videopericardioscopy, uncomplicated, anatomically accurate left heart epicardial pacing lead implantation can be achieved without thoracotomy.

Characteristics of the umbilical artery velocity waveform as function of measurement site.

1990-01-01

In 30 uncomplicated singleton pregnancies, varying in duration between 24 and 40 weeks, the variability of the flow velocity waveform (FVW) along the course of the umbilical artery was investigated. Blood flow velocities were recorded at 4 locations in the vessel: within the fetal abdomen, 0-5 cm from the origin of the umbilical cord, in the free-floating part, and 0-5 cm from its insertion in the placenta. From the Doppler signals recorded, the pulsatility index (PI) and a parameter for the frequency distribution index (FDI) were calculated. PI values differed among the locations, but no unequivocal tendency could be demonstrated. Statistical analysis, including multiple regression analysis for maternal and menstrual age and fetal heart rate, showed no significant difference in PI and FDI values for any of the 4 locations. It can be concluded that in uncomplicated pregnancies, possible changes in FVW (quantified by PI) along the course of the umbilical artery have no clinical relevance. Therefore, standardization for the sampling site when measuring PI in this vessel seems to be unnecessary.

BACKGROUND AND AIMS. Arterial stiffness evaluated as pulse wave velocity, is an early marker of vascular damage and an independent predictor for cardiovascular events. We investigated if the insulin resistance/hyperinsulinemia chronic hepatitis C virus infection-related could influence arterial stiffness. METHODS. We enrolled 260 outpatients matched for age, body mass index, gender, ethnicity: 52 with never-treated uncomplicated chronic hepatitis C virus infection (HCV(+)), 104 never-treated hypertensives (HT) and 104 healthy subjects (NT). Pulse wave velocity was evaluated by a validated system employing high-fidelity applanation tonometry. We also measured: fasting plasma glucose and insulin, total, LDL- and HDL-cholesterol, triglyceride, creatinine, e-GFR-EPI, HOMA, quantitative HCV-RNA. RESULTS. HCV(+) patients with respect to NT had an increased pulse wave velocity (7.9 ± 2.1 vs 6.4 ± 2.1 m/s; P < 0.0001), similar to that observed in HT group (8.8 ± 3.2 m/s). HCV(+) patients, in comparison with NT, had higher triglyceride, creatinine, fasting insulin and HOMA (3.2 ± 1.3 vs 2.5 ± 1.0; P < 0.0001). At linear regression analysis, the correlation between pulse wave velocity and HOMA was similar in HT (r = 0.380, P < 0.0001) and HCV(+) (r = 0.369, P = 0.004) groups. At multiple regression analysis, HOMA resulted the major determinant of pulse wave velocity in all groups, explaining respectively 11.8%, 14.4% and 13.6% of its variation in NT, HT and HCV(+). At correlational analysis hepatitis C virus-RNA and HOMA demonstrated a strong and linear relationship between them, explaining the 72.4% of their variation (P = 0.022). CONCLUSIONS. We demonstrated a significant and direct correlation between HOMA and pulse wave velocity in HCV(+) patients, similar to that observed in hypertensives. Copyright © 2014 Elsevier Ireland Ltd.

Measures of socioeconomic disadvantage may enable improved targeting of programs to prevent rehospitalizations, but obtaining such information directly from patients can be difficult. Measures of U.S. neighborhood socioeconomic disadvantage are more readily available but are rarely used clinically. To evaluate the association between neighborhood socioeconomic disadvantage at the census block group level, as measured by the Singh validated area deprivation index (ADI), and 30-day rehospitalization. Retrospective cohort study. United States. Random 5% national sample of Medicare patients discharged with congestive heart failure, pneumonia, or myocardial infarction between 2004 and 2009 (n = 255,744). Medicare data were linked to 2000 census data to construct an ADI for each patient's census block group, which were then sorted into percentiles by increasing ADI. Relationships between neighborhood ADI grouping and 30-day rehospitalization were evaluated using multivariate logistic regression models, controlling for patient sociodemographic characteristics, comorbid conditions and severity, and index hospital characteristics. The 30-day rehospitalization rate did not vary significantly across the least disadvantaged 85% of neighborhoods, which had an average rehospitalization rate of 21%. However, within the most disadvantaged 15% of neighborhoods, rehospitalization rates increased from 22% to 27% with worsening ADI. This relationship persisted after full adjustment, with the most disadvantaged neighborhoods having a rehospitalization risk (adjusted risk ratio, 1.09 [95% CI, 1.05 to 1.12]) similar to that of chronic pulmonary disease (adjusted risk ratio, 1.06 [CI, 1.04 to 1.08]) and greater than that of uncomplicated diabetes (adjusted risk ratio, 0.95 [CI, 0.94 to 0.97]). No direct markers of care quality or access. Residence within a disadvantaged U.S. neighborhood is a rehospitalization predictor of magnitude similar to chronic pulmonary disease. Measures of neighborhood disadvantage, such as the ADI, could potentially be used to inform policy and care after hospital discharge.

Chiropractic and self-care for back-related leg pain: design of a randomized clinical trial

PubMed Central

2011-01-01

Background Back-related leg pain (BRLP) is a common variation of low back pain (LBP), with lifetime prevalence estimates as high as 40%. Often disabling, BRLP accounts for greater work loss, recurrences, and higher costs than uncomplicated LBP and more often leads to surgery with a lifetime incidence of 10% for those with severe BRLP, compared to 1-2% for those with LBP. In the US, half of those with back-related conditions seek CAM treatments, the most common of which is chiropractic care. While there is preliminary evidence suggesting chiropractic spinal manipulative therapy is beneficial for patients with BRLP, there is insufficient evidence currently available to assess the effectiveness of this care. Methods/Design This study is a two-site, prospective, parallel group, observer-blinded randomized clinical trial (RCT). A total of 192 study patients will be recruited from the Twin Cities, MN (n = 122) and Quad Cities area in Iowa and Illinois (n = 70) to the research clinics at WHCCS and PCCR, respectively. It compares two interventions: chiropractic spinal manipulative therapy (SMT) plus home exercise program (HEP) to HEP alone (minimal intervention comparison) for patients with subacute or chronic back-related leg pain. Discussion Back-related leg pain (BRLP) is a costly and often disabling variation of the ubiquitous back pain conditions. As health care costs continue to climb, the search for effective treatments with few side-effects is critical. While SMT is the most commonly sought CAM treatment for LBP sufferers, there is only a small, albeit promising, body of research to support its use for patients with BRLP. This study seeks to fill a critical gap in the LBP literature by performing the first full scale RCT assessing chiropractic SMT for patients with sub-acute or chronic BRLP using important patient-oriented and objective biomechanical outcome measures.

2010-01-01

Background Infection with Helicobacter pylori triggers a chronic gastric inflammation that can progress to atrophy and gastric adenocarcinoma. Polarization of macrophages is a characteristic of both cancer and infection, and may promote progression or resolution of disease. However, the role of macrophages and their polarization during H. pylori infection has not been well defined. Methodology/Principal Findings By using a mouse model of infection and gastric biopsies from 29 individuals, we have analyzed macrophage recruitment and polarization during H. pylori infection by flow cytometry and real-time PCR. We found a sequential recruitment of neutrophils, eosinophils and macrophages to the gastric mucosa of infected mice. Gene expression analysis of stomach tissue and sorted macrophages revealed that gastric macrophages were polarized to M1 after H. pylori infection, and this process was substantially accelerated by prior vaccination. Human H. pylori infection was characterized by a mixed M1/M2 polarization of macrophages. However, in H. pylori-associated atrophic gastritis, the expression of inducible nitric oxide synthase was markedly increased compared to uncomplicated gastritis, indicative of an enhanced M1 macrophage polarization in this pre-malignant lesion. Conclusions/Significance These results show that vaccination of mice against H. pylori amplifies M1 polarization of gastric macrophages, and that a similar enhanced M1 polarization is present in human H. pylori-induced atrophic gastritis.

2016-01-01

Uropathogenic Escherichia coli (UPEC) is the primary cause of uncomplicated urinary tract infections (UTIs). Whereas most infections are isolated cases, 1 in 40 women experience recurrent UTIs. The rise in antibiotic resistance has complicated the management of chronic UTIs and necessitates new preventative strategies. Currently, no UTI vaccines are approved for use in the United States, and the development of a highly effective vaccine remains elusive. Here, we have pursued a strategy for eliciting protective immunity by vaccinating with small molecules required for pathogenesis, rather than proteins or peptides. Small iron-chelating molecules called siderophores were selected as antigens to vaccinate against UTI for this vaccine strategy. These pathogen-associated stealth siderophores evade host immune defenses and enhance bacterial virulence. Previous animal studies revealed that vaccination with siderophore receptor proteins protects against UTI. The poor solubility of these integral outer-membrane proteins in aqueous solutions limits their practical utility. Because their cognate siderophores are water soluble, we hypothesized that these bacterial-derived small molecules are prime vaccine candidates. To test this hypothesis, we immunized mice with siderophores conjugated to an immunogenic carrier protein. The siderophore–protein conjugates elicited an adaptive immune response that targeted bacterial stealth siderophores and protected against UTI. Our study has identified additional antigens suitable for a multicomponent UTI vaccine and highlights the potential use of bacterial-derived small molecules as antigens in vaccine therapies.

Diverticular disease is a chronic and common condition, and yet the impact of diverticular disease in primary care is largely unknown. The diagnosis of diverticular disease relies on the demonstration of diverticula in the colon, and the necessary investigations are often not available in primary care. The specificity and sensitivity of symptoms, clinical signs and laboratory tests alone are generally low and consequently the diagnostic process will be characterized by uncertainty. Also, the criteria for symptomatic uncomplicated diverticular disease in the absence of macroscopic inflammation are not clearly defined. Therefore both the prevalence of diverticular disease and the incidence of diverticulitis in primary care are unknown. Current recommendations for treatment and follow-up of patients with acute diverticulitis are based on studies where the diagnosis has been verified by computerized tomography. The results cannot be directly transferred to primary care where the diagnosis has to rely on the interpretation of symptoms and signs. Therefore, one must allow for greater diagnostic uncertainty, and safety netting in the event of unexpected development of the condition is an important aspect of the management of diverticulitis in primary care. The highest prevalence of diverticular disease is found among older patients, where multimorbidity and polypharmacy is common. The challenge is to remember the possible contribution of diverticular disease to the patient's overall condition and to foresee its implications in terms of advice and treatment in relation to other diseases.

Uropathogenic Escherichia coli (UPEC) is the primary cause of uncomplicated urinary tract infections (UTIs). Whereas most infections are isolated cases, 1 in 40 women experience recurrent UTIs. The rise in antibiotic resistance has complicated the management of chronic UTIs and necessitates new preventative strategies. Currently, no UTI vaccines are approved for use in the United States, and the development of a highly effective vaccine remains elusive. Here, we have pursued a strategy for eliciting protective immunity by vaccinating with small molecules required for pathogenesis, rather than proteins or peptides. Small iron-chelating molecules called siderophores were selected as antigens to vaccinate against UTI for this vaccine strategy. These pathogen-associated stealth siderophores evade host immune defenses and enhance bacterial virulence.

Mefloquine (MQ) has been used for the treatment of malaria since the mid-1980s, first as monotherapy or as fixed combination with sulfadoxine-pyrimethamine (MSP) and since the mid-1990s in combination with artesunate. There is a renewed interested in MQ as part of a triple therapy for the treatment of multi-drug resistance P. falciparum malaria. The widespread use of MQ beyond south-East Asia has been constrained by reports of poor tolerability. Here we present the side effect profile of MQ for the treatment of uncomplicated malaria on the Thai-Myanmar/Cambodia borders. In total 19,850 patients received seven different regimens containing either 15 or 24-25 mg/kg of MQ, the latter given either as a single dose, or split over two or three days. The analysis focused on (predominantly) gastrointestinal and neuropsychiatric events as compared to the new fixed dose combination of MQ plus artesunate given as equal doses of 8 mg/kg MQ per day over three days. Gastrointestinal side effects were dose-dependent and associated with the severity of malaria symptoms. Serious neuropsychiatric side effects associated with MQ use were rare: for a single 25 mg/kg dose it was 11.9 per 10,000 treatments (95% confidence interval, CI, 4-285) vs. 7.8 (3-15) for the 15 mg/kg dose. The risk with 25 mg/kg was much higher when it was given as repeat dosing in patients who had failed treatment with 15 mg/kg MQ in the preceding month; (RR 6.57 (95% CI 1.33 to 32.4), p = 0.0077). MQ was best tolerated as 15 mg/kg or as 24 mg/kg when given over three days in combination with artesunate. We conclude that the tolerance of a single dose of MQ in the treatment of uncomplicated malaria is moderate, but can be improved by administering it as a split dose over three days.

Many surgeons use a stent after ureteroscopic lithotripsy (URSL). For short-term stenting purposes, a surgeon has the choice of either a tethered or a non-tethered stent. Stents may be associated with complications that entail an additional cost to their use. There is a paucity of data on the direct healthcare cost of using stent type after either primary or secondary URSL. We retrospectively reviewed medical records for patients who underwent URSL for uncomplicated urolithiasis between January 2013 and December 2013 at two tertiary referral hospitals. Costs data was sourced from the costing department with complete data available for 134 patients. The overall medical care cost was estimated by computing the cost of surgery, stent-related emergency department presentations, re-admissions and stent removal. A total of 113 patients had tethered stents and 21 had non-tethered stents, with similar age and gender composition between the two groups and complications rates. The mean cost of URSL and stent placement was A$3071.7 ± A$906.8 versus A$3423.8 ± A$808.4 (P = 0.049), mean cost of managing complications was A$309.4 ± A$1744.8 versus A$31.3 ± A$98.9 (P = 0.096), mean cost of out-patient clinic stent removal was A$222.5 ± A$60 versus A$1013.6 ± A$75.4 (P < 0.001) for endoscopic stent removal, overall mean cost of care was A$3603.6 ± A$1896.7 versus A$4468.1 ± A$820.8 (P = 0.042) for tethered and non-tethered stents, respectively. It is cheaper to use a tethered ureteric stent compared with non-tethered stents for short-term stenting after uncomplicated URSL, with a mean cost saving of A$864.5. © 2017 Royal Australasian College of Surgeons.

Most patients with Crohn's disease (CD) are diagnosed with the uncomplicated inflammatory form of the disease (Montreal stage B1). However, the majority of them will progress to complicated stricturing (B2) and penetrating (B3) CD during their lifetimes. The aim of our study was to identify the genetic factors associated with time to progression from uncomplicated to complicated CD. Patients with an inflammatory phenotype at diagnosis were followed up for 10 years. Genotyping was carried out using Illumina ImmunoChip. After quality control, association analyses, Bonferroni's adjustments, linear and Cox's regression, and Kaplan-Meier analysis were carried out for 111 patients and Manhattan plots were constructed. Ten years after diagnosis, 39.1% of the patients still had the inflammatory form and 60.9% progressed to complicated disease, with an average time to progression of 5.91 years. Ileal and ileocolonic locations were associated with the complicated CD (P=1.08E-03). We found that patients with the AA genotype at single-nucleotide polymorphism rs16857259 near the gene CACNA1E progressed to the complicated form later (8.80 years) compared with patients with the AC (5.11 years) or CC (2.00 years) genotypes (P=3.82E-07). In addition, nine single-nucleotide polymorphisms (near the genes RASGRP1, SULF2, XPO1, ZBTB44, HLA DOA/BRD2, HLA DRB1/HLA DQA1, PPARA, PUDP, and KIAA1614) showed a suggestive association with disease progression (P<10). Multivariate Cox's regression analysis on the basis of clinical and genetic data confirmed the association of the selected model with disease progression (P=5.73E-16). Our study confirmed the association between the locus on chromosome 1 near the gene CACNA1E with time to progression from inflammatory to stricturing or penetrating CD. Predicting the time to progression is useful to the clinician in terms of individualizing patients' management.

to compare the client satisfaction of women with uncomplicated pregnancies at the onset of labor who were transferred across care levels during childbirth and women who were not transferred across care levels in the Dutch perinatal healthcare system, and-if there are differences-to identify the variables that may explain them. the research entailed a population-based study of women with uncomplicated pregnancies at the onset of labor living in the catchment area of a Dutch Neonatal Intensive Care Unit (NICU) in the eastern part of the Netherlands who gave birth between April 2014 and September 2014. Respondents completed a validated questionnaire (n = 842; mean age 30.7 years). Client satisfaction, measured on a 10-point scale, was assessed within 12 weeks after childbirth. of the 842 respondents, 277 women experienced a transfer of care during childbirth, and 565 women were not transferred. The client satisfaction of women who were transferred across care levels (mean 8.04; SD 1.4) was significantly lower (p<0.001) than that of women who were not transferred across care levels (mean 8.78; SD 0.9). Seven variables together explained 93.2% of the difference in client satisfaction. Explanatory pregnancy and childbirth variables were perceived health problems for the mother and medical interventions during childbirth. Explanatory clients' experiences with the care process variables were respect, prompt attention, quality of basic amenities, social consideration, and choice and continuity. women were highly satisfied with the care they received, although transfers across care levels during childbirth were associated with substantially lower client satisfaction. The differences in client satisfaction between transferred and non-transferred women can largely be explained by pregnancy and childbirth characteristics, and by clients' experiences with the care process.

Increased microparticle (MP) shedding by placental trophoblasts contributes to maternal vascular inflammatory response and endothelial dysfunction in preeclampsia. Vitamin D has beneficial effects in pregnancy; however, its effect on trophoblast MP release has not been investigated. To investigate if vitamin D could protect trophoblasts from oxidative stress-induced MP release. Placental trophoblasts were isolated from uncomplicated and preeclamptic placentas. Effects of vitamin D on MP release induced by oxidative stress inducer CoCl2 were studied. Annexin V+ MPs were assessed by flow cytometry. Expression of caveolin-1, endothelial nitric oxide synthase (eNOS), procaspase-3, cleaved caspase-3, and Rho-associated coiled-coil protein kinase 1 (ROCK1) in trophoblasts and trophoblast-derived MPs were determined by Western blot. Trophoblasts from preeclamptic pregnancies released significantly more MPs than cells from uncomplicated pregnancies (P < 0.01). CoCl2-induced increase in MP release was associated with upregulation of caveolin-1 and downregulation of eNOS expression in trophoblasts (P < 0.05), which could be attenuated by 1,25(OH)2D3. Moreover, 1,25(OH)2D3 could also inhibit CoCl2-induced procaspase-3 cleavage and ROCK1 activation in trophoblasts. Consistently, CoCl2-induced upregulation of procaspase-3, cleaved caspase-3, and ROCK1 expression in trophoblast-derived MPs were also reduced in cells treated with 1,25(OH)2D3. Placental trophoblasts from preeclamptic pregnancies released more MP than cells from uncomplicated pregnancies. Oxidative stress-induced increase in MP shedding is associated with upregulation of caveolin-1 and downregulation of eNOS expression in placental trophoblasts. Inhibition of caspase-3 cleavage and ROCK1 activation, together with upregulation of eNOS expression, could be the potential cellular/molecular mechanism(s) of vitamin D protective effects on placental trophoblasts.

Fentanyl overdoses are increasing and few data guide emergency department (ED) management. We evaluate the safety of an ED protocol for patients with presumed fentanyl overdose. At an urban ED, we used administrative data and explicit chart review to identify and describe consecutive patients with uncomplicated presumed fentanyl overdose (no concurrent acute medical issues) from September to December 2016. We linked regional ED and provincial vital statistics databases to ascertain admissions, revisits, and mortality. Primary outcome was a composite of admission and death within 24 hours. Other outcomes included treatment with additional ED naloxone, development of a new medical issue while in the ED, and length of stay. A prespecified subgroup analysis assessed low-risk patients with normal triage vital signs. There were 1,009 uncomplicated presumed fentanyl overdose, mainly by injection. Median age was 34 years, 85% were men, and 82% received out-of-hospital naloxone. One patient was hospitalized and one discharged patient died within 24 hours (combined outcome 0.2%; 95% confidence interval [CI] 0.04% to 0.8%). Sixteen patients received additional ED naloxone (1.6%; 95% CI 1.0% to 2.6%), none developed a new medical issue (0%; 95% CI 0% to 0.5%), and median length of stay was 173 minutes (interquartile range 101 to 267). For 752 low-risk patients, no patients were admitted or developed a new issue, and one died postdischarge; 3 (0.4%; 95% CI 0.01% to 1.3%) received ED naloxone. In our cohort of ED patients with uncomplicated presumed fentanyl overdose-typically after injection-deterioration, admission, mortality, and postdischarge complications appear low; the majority can be discharged after brief observation. Patients with normal triage vital signs are unlikely to require ED naloxone. Copyright © 2018 American College of Emergency Physicians. Published by Elsevier Inc. All rights reserved.

Purpose: Level I evidence demonstrates equivalent pain response after single-fraction (SF) or multifraction (MF) radiation therapy (RT) for bone metastases. The purpose of this study is to provide additional data to inform the incidence and predictors of adverse outcomes after RT for spine metastases. Methods and Materials: At a single institution, 299 uncomplicated spine metastases (without cord compression, prior RT, or surgery) treated with RT from 2008 to 2013 were retrospectively reviewed. The spinal instability neoplastic score (SINS) was used to assess spinal instability. The primary outcome was time to first spinal adverse event (SAE) at the site, including symptomaticmore » vertebral fracture, hospitalization for site-related pain, salvage surgery, interventional procedure, new neurologic symptoms, or cord compression. Fine and Gray's multivariable model assessed associations of the primary outcome with SINS, SF RT, and other significant baseline factors. Propensity score matched analysis further assessed the relationship of SF RT to first SAEs. Results: The cumulative incidence of first SAE after SF RT (n=66) was 6.8% at 30 days, 16.9% at 90 days, and 23.6% at 180 days. For MF RT (n=233), the incidence was 3.5%, 6.4%, and 9.2%, respectively. In multivariable analysis, SF RT (hazard ratio [HR] = 2.8, 95% confidence interval [CI] 1.5-5.2, P=.001) and SINS ≥11 (HR=2.5 , 95% CI 1.3-4.9, P=.007) were predictors of the incidence of first SAE. In propensity score matched analysis, first SAEs had developed in 22% of patients with SF RT versus 6% of those with MF RT cases (HR=3.9, 95% CI 1.6-9.6, P=.003) at 90 days after RT. Conclusion: In uncomplicated spinal metastases treated with RT alone, spinal instability with SINS ≥11 and SF RT were associated with a higher rate of SAEs.« less

The association between severe malaria and Plasmodium vivax species is contentious. On the Thai-Myanmar border, all pregnant women are followed systematically with active weekly malaria screening. Over a 27-year period of providing antenatal care, 48,983 have been prospectively followed until pregnancy outcome (miscarriage or delivery) and 4,298 women have had P. vivax detected at least once. Reported here is the first known P. vivax-associated death amongst these women. The initial patient presentation was of uncomplicated P. vivax (0.5% parasitaemia) in a term, multigravida woman who responded rapidly to oral artesunate and mefloquine treatment, clearing her blood stage parasites within 48 hours. The patient appeared well, was ambulatory and due to be discharged but became unwell with acute respiratory distress syndrome (ARDS) requiring ventilation three days (67 hours) into treatment. Despite induction and delivery of a stillborn foetus, ventilatory requirements increased and the patient died on day 7. The patient had a low body mass index. Sensitive detection with nested PCR confirmed only the presence of P. vivax species and concomitant infections such as tuberculosis and human immunodeficiency virus (HIV) were also ruled out. The contemporaneous treatment of acute uncomplicated P. vivax and the onset of ARDS on day 3 in this patient implies a possible but unconfirmed association with death in this patient. Assuming this death was caused by P. vivax, the risk of ARDS-related maternal mortality in this setting did not differ significantly between Plasmodium falciparum and P. vivax (0.24 per 1,000 (1/4,158) versus 0.23 per 1,000 (1/4,298), contrary to the increased risk of maternal mortality from P. falciparum compared to P. vivax, 2.89 per 1,000 (12/4,158) versus 0.23 per 1,000 (1/4,298), P = 0.003.

Malaria during pregnancy, particularly Plasmodium falciparum malaria, has been linked to increased morbidity and mortality, which must be reduced by both preventive measures and effective case management. The World Health Organization (WHO) recommends artemisinin-based combination therapy (ACT) to treat uncomplicated falciparum malaria during the second and third trimesters of pregnancy, and quinine plus clindamycin during the first trimester. However, the national policies of many African countries currently recommend quinine throughout pregnancy. Therefore, the aim of this article is to provide a summary of the available data on the safety and efficacy of artemether-lumefantrine (AL) in pregnancy. An English-language search identified 16 publications from 1989 to October 2011 with reports of artemether or AL exposure in pregnancy, including randomized clinical trials, observational studies and systematic reviews. Overall, there were 1,103 reports of AL use in pregnant women: 890 second/third trimester exposures; 212 first trimester exposures; and one case where the trimester of exposure was not reported. In the second and third trimesters, AL was not associated with increased adverse pregnancy outcomes as compared with quinine or sulphadoxine-pyrimethamine, showed improved tolerability relative to quinine, and its efficacy was non-inferior to quinine. There is evidence to suggest that the pharmacokinetics of anti-malarial drugs may change in pregnancy, although the impact on efficacy and safety needs to be studied further, especially since the majority of studies report high cure rates and adequate tolerability. As there are fewer reports of AL safety in the first trimester, additional data are required to assess the potential to use AL in the first trimester. Though the available safety and efficacy data support the use of AL in the second and third trimesters, there is still a need for further information. These findings reinforce the WHO recommendation to treat uncomplicated falciparum malaria with quinine plus clindamycin in early pregnancy and ACT in later pregnancy.

Background Appendectomy is considered the gold standard treatment for acute appendicitis. Recently the need for surgery has been challenged in both adults and children. In children there is growing clinician, patient and parental interest in non-operative treatment of acute appendicitis with antibiotics as opposed to surgery. To date no multicentre randomised controlled trials that are appropriately powered to determine efficacy of non-operative treatment (antibiotics) for acute appendicitis in children compared with surgery (appendectomy) have been performed. Methods Multicentre, international, randomised controlled trial with a non-inferiority design. Children (age 5–16 years) with a clinical and/or radiological diagnosis of acute uncomplicated appendicitis will be randomised (1:1 ratio) to receive either laparoscopic appendectomy or treatment with intravenous (minimum 12 hours) followed by oral antibiotics (total course 10 days). Allocation to groups will be stratified by gender, duration of symptoms (> or <48 hours) and centre. Children in both treatment groups will follow a standardised treatment pathway. Primary outcome is treatment failure defined as additional intervention related to appendicitis requiring general anaesthesia within 1 year of randomisation (including recurrent appendicitis) or negative appendectomy. Important secondary outcomes will be reported and a cost-effectiveness analysis will be performed. The primary outcome will be analysed on a non-inferiority basis using a 20% non-inferiority margin. Planned sample size is 978 children. Discussion The APPY trial will be the first multicentre randomised trial comparing non-operative treatment with appendectomy for acute uncomplicated appendicitis in children. The results of this trial have the potential to revolutionise the treatment of this common gastrointestinal emergency. The randomised design will limit the effect of bias on outcomes seen in other studies. Trial registration number clinicaltrials.gov: NCT02687464. Registered on Jan 13th 2016. PMID:29637088

2008-01-01

Emerging antimicrobial resistance among uropathogens makes the management of acute uncomplicated cystitis increasingly challenging. Few prospective data are available on the risk factors for resistance to trimethoprim-sulfamethoxazole (TMP-SMX), the drug of choice in most settings. In order to evaluate this, we prospectively enrolled women 18 to 50 years of age presenting to an urban primary care practice with symptoms of cystitis. Potentially eligible women provided a urine sample for culture and completed a questionnaire regarding putative risk factors for TMP-SMX resistance. Escherichia coli isolates were tested for clonal group A (CGA) membership by a fumC-specific PCR. Of 165 women with cystitis symptoms, 103 had a positive urine culture and were eligible for participation. E. coli was the predominant uropathogen (86%). Fifteen (14.6%) women had a TMP-SMX-resistant (TMP-SMXr) organism (all of which were E. coli). Compared with the women who had a TMP-SMX-susceptible organism, women in the TMP-SMXr group were more likely to have traveled (odds ratio [OR], 15.4; 95% confidence interval [CI], 4.4 to 54.3; P < 0.001) and to be Asian (OR, 6.1; 95% CI, 1.0 to 36.4; P = 0.048). CGA was also independently associated with TMP-SMX resistance (OR, 105; 95% CI, 6.3 to 1,777.6; P = 0.001). No association with TMP-SMX resistance was demonstrated for the use of either TMP-SMX or another antibiotic in the past 3 months or with having a child in day care. Among these women with acute uncomplicated cystitis, Asian race and recent travel were independently associated with TMP-SMX resistance. TMP-SMXr isolates were more likely to belong to CGA. Knowledge of these risk factors for TMP-SMX resistance could facilitate the accurate selection of empirical therapy. PMID:18086847

Systematic Review and Meta-Analysis of Randomized Clinical Trials in the Treatment of Human Brucellosis

2012-01-01

Background Brucellosis is a persistent health problem in many developing countries throughout the world, and the search for simple and effective treatment continues to be of great importance. Methods and Findings A search was conducted in MEDLINE and in the Cochrane Central Register of Controlled Trials (CENTRAL). Clinical trials published from 1985 to present that assess different antimicrobial regimens in cases of documented acute uncomplicated human brucellosis were included. The primary outcomes were relapse, therapeutic failure, combined variable of relapse and therapeutic failure, and adverse effect rates. A meta-analysis with a fixed effect model was performed and odds ratio with 95% confidence intervals were calculated. A random effect model was used when significant heterogeneity between studies was verified. Comparison of combined doxycycline and rifampicin with a combination of doxycycline and streptomycin favors the latter regimen (OR = 3.17; CI95% = 2.05–4.91). There were no significant differences between combined doxycycline-streptomycin and combined doxycycline-gentamicin (OR = 1.89; CI95% = 0.81–4.39). Treatment with rifampicin and quinolones was similar to combined doxycycline-rifampicin (OR = 1.23; CI95% = 0.63–2.40). Only one study assessed triple therapy with aminoglycoside-doxycycline-rifampicin and only included patients with uncomplicated brucellosis. Thus this approach cannot be considered the therapy of choice until further studies have been performed. Combined doxycycline/co-trimoxazole or doxycycline monotherapy could represent a cost-effective alternative in certain patient groups, and further studies are needed in the future. Conclusions Although the preferred treatment in uncomplicated human brucellosis is doxycycline-aminoglycoside combination, other treatments based on oral regimens or monotherapy should not be rejected until they are better studied. Triple therapy should not be considered the current treatment of choice. PMID:22393379

The pharmacokinetic and pharmacodynamic properties of a new pediatric formulation of artemether-lumefantrine, dispersible tablet, were determined within the context of a multicenter, randomized, parallel-group study. In an exploratory approach, we compared a new pediatric formulation with the tablet formulation administered crushed in the treatment of African children with uncomplicated Plasmodium falciparum malaria. Patients were randomized to 3 different dosing groups (weights of 5 to <15 kg, 15 and <25 kg, and 25 to <35 kg). Treatment was administered twice daily over 3 days. Plasma concentrations of artemether and its active metabolite, dihydroartemisinin (DHA), were determined at 1 and 2 h after the first dose of dispersible (n = 91) and crushed (n = 93) tablets. A full pharmacokinetic profile of lumefantrine was reconstituted on the basis of 310 (dispersible tablet) and 315 (crushed tablet) plasma samples, collected at 6 different time points (1 sample per patient). Dispersible and crushed tablets showed similar artemether and DHA maximum concentrations in plasma (C(max)) for the different body weight groups, with overall means of 175 ± 168 and 190 ± 168 ng/ml, respectively, for artemether and 64.7 ± 58.1 and 63.7 ± 65.0 ng/ml, respectively, for DHA. For lumefantrine, the population C(max) were 6.3 μg/ml (dispersible tablet) and 7.7 μg/ml (crushed tablet), whereas the areas under the concentration-time curves from time zero to the time of the last quantifiable plasma concentration measured were 574 and 636 μg · h/ml, respectively. For both formulations, descriptive quintile analyses showed no apparent association between artemether/DHA C(max) and parasite clearance time or between the lumefantrine C(max) and the occurrence of adverse events or corrected QT interval changes. The results suggest that the dispersible tablet provides adequate systemic exposure to artemether, DHA, and lumefantrine in African children with uncomplicated P. falciparum malaria.

Although clinical practice guidelines for the management of hypertension exist in Canada, the rate of contemporary blood pressure (BP) control remains unclear. In the Primary Care Audit of Global Risk Management (PARADIGM) study, 3015 healthy, middle-aged Canadians, free of cardiovascular disease (CVD) or diabetes were evaluated. In this analysis, we characterized the CVD risk factors, treatment patterns, and BP control rates in subjects with uncomplicated hypertension. A total of 917 subjects (30.4%) had a diagnosis of hypertension. The median age was 59 ± 8 years. The mean treated systolic/diastolic BP were 134 ± 14 mm Hg/82 ± 9 mm Hg, respectively. CVD risk factors included past/current smoking (35.9%), abdominal obesity (62.5%), and dyslipidemia (59.4%). Using the Framingham Risk Score, 20.4%, 41.0%, and 38.5% of the subjects were at low, intermediate, and high risk, respectively. Of the 88% with treated hypertension, 46.9%, 38.7%, and 14.3% received 1, 2, or ≥3 drugs, respectively. The rate of BP control was 57.4% (systolic BP < 140 and diastolic BP < 90 mm Hg). The rate of BP control was lower in patients prescribed diuretic monotherapy (53.2%) vs those who received angiotensin converting enzyme inhibitor/angiotensin receptor blocker monotherapy (66.5%; P < 0.01). Importantly, BP control deteriorated with increasing Framingham Risk Score, and was lower in patients with metabolic syndrome vs those without (P < 0.00001 for both). PARADIGM demonstrated that CVD risk factors are prevalent in Canadians with uncomplicated hypertension. BP control was modest (57.4%) and was lowest in patients prescribed diuretic monotherapy and in those at highest CVD risk. Despite the success of national hypertension strategies, enhanced efforts are warranted to improve BP control in Canada. Copyright © 2015 Canadian Cardiovascular Society. Published by Elsevier Inc.

Background Multiplicity of infection (MOI) refers to the average number of distinct parasite genotypes concurrently infecting a patient. Although several studies have reported on MOI and the frequency of multiclonal infections in Plasmodium falciparum, there is limited data on Plasmodium vivax. Here, MOI and the frequency of multiclonal infections were studied in areas from South America where P. vivax and P. falciparum can be compared. Methodology/Principal Findings As part of a passive surveillance study, 1,328 positive malaria patients were recruited between 2011 and 2013 in low transmission areas from Colombia. Of those, there were only 38 P. vivax and 24 P. falciparum clinically complicated cases scattered throughout the time of the study. Samples from uncomplicated cases were matched in time and location with the complicated cases in order to compare the circulating genotypes for these two categories. A total of 92 P. vivax and 57 P. falciparum uncomplicated cases were randomly subsampled. All samples were genotyped by using neutral microsatellites. Plasmodium vivax showed more multiclonal infections (47.7%) than P. falciparum (14.8%). Population genetics and haplotype network analyses did not detect differences in the circulating genotypes between complicated and uncomplicated cases in each parasite. However, a Fisher exact test yielded a significant association between having multiclonal P. vivax infections and complicated malaria. No association was found for P. falciparum infections. Conclusion The association between multiclonal infections and disease severity in P. vivax is consistent with previous observations made in rodent malaria. The contrasting pattern between P. vivax and P. falciparum could be explained, at least in part, by the fact that P. vivax infections have lineages that were more distantly related among them than in the case of the P. falciparum multiclonal infections. Future research should address the possible role that acquired immunity and exposure may have on multiclonal infections and their association with disease severity. PMID:26751811

Plasmodium knowlesi can cause severe and fatal human malaria in Southeast Asia. Rapid diagnosis of all Plasmodium species is essential for initiation of effective treatment. Rapid diagnostic tests (RDTs) are sensitive for detection of uncomplicated and severe falciparum malaria but have not been systematically evaluated in knowlesi malaria. At a tertiary referral hospital in Sabah, Malaysia, we prospectively evaluated the sensitivity of two combination RDTs for the diagnosis of uncomplicated and severe malaria from all three potentially fatal Plasmodium species, using a pan-Plasmodium lactate dehydrogenase (pLDH)-P. falciparum histidine-rich protein 2 (PfHRP2) RDT (First Response) and a pan-Plasmodium aldolase-PfHRP2 RDT (ParaHIT). Among 293 hospitalized adults with PCR-confirmed Plasmodium monoinfection, the sensitivity of the pLDH component of the pLDH-PfHRP2 RDT was 74% (95/129; 95% confidence interval [CI], 65 to 80%), 91% (110/121; 95% CI, 84 to 95%), and 95% (41/43; 95% CI, 85 to 99%) for PCR-confirmed P. knowlesi, P. falciparum, and P. vivax infections, respectively, and 88% (30/34; 95% CI, 73 to 95%), 90% (38/42; 95% CI, 78 to 96%), and 100% (12/12; 95% CI, 76 to 100%) among patients tested before antimalarial treatment was begun. Sensitivity in severe malaria was 95% (36/38; 95% CI, 83 to 99), 100% (13/13; 95% CI, 77 to 100), and 100% (7/7; 95% CI, 65 to 100%), respectively. The aldolase component of the aldolase-PfHRP2 RDT performed poorly in all Plasmodium species. The pLDH-based RDT was highly sensitive for the diagnosis of severe malaria from all species; however, neither the pLDH- nor aldolase-based RDT demonstrated sufficiently high overall sensitivity for P. knowlesi. More sensitive RDTs are needed in regions of P. knowlesi endemicity.

Objective This multinational, multicentre, prospective, randomised, double blind, parallel group, non‐inferiority study compared the efficacy and safety of moxifloxacin monotherapy with ofloxacin plus metronidazole in women with uncomplicated pelvic inflammatory disease. Methods Women from hospitals throughout 13 countries received a 14 day course of either oral moxifloxacin, 400 mg once daily (n = 384), or oral ofloxacin, 400 mg twice daily plus oral metronidazole, 500 mg twice daily (n = 365). Results Of the 741 patients in the intent to treat (ITT) population, 564 (74.2%) were valid for the per protocol (PP) analyses; 112 (19.9%) of these were included in the microbiologically valid population (MBV). Clinical resolution rates in the PP population at the test of cure visit (TOC, 5–24 days post‐therapy, primary efficacy end point) were 90.2% (248/275) for moxifloxacin and 90.7% (262/289) for ofloxacin plus metronidazole (95% CI: −5.7% to 4.0%). At follow up (28–42 days post‐therapy), resolution rates in the PP population were 85.8% (236/275) and 87.9% (254/289) for moxifloxacin and comparator, respectively (95% CI: −8.0% to 3.1%). Bacteriological success rates in the MBV population at TOC were 87.5% (49/56) for moxifloxacin and 82.1% (46/56) for comparator (95% CI: −8.3% to 18.8%). Against Chlamydia trachomatis and Neisseria gonorrhoeae, bacteriological success rates with moxifloxacin were 88.5% (23/26) and 100% (13/13) and for comparator 85.7% (18/21) and 81.8% (18/22), respectively. Drug related adverse events occurred less frequently with moxifloxacin (22.5% (85/378)) versus the comparator (30.9% (112/363)) (p = 0.01). Conclusion In uncomplicated PID, once daily moxifloxacin monotherapy was clinically and bacteriologically as efficacious as twice daily ofloxacin plus metronidazole therapy and was associated with fewer drug related adverse events.

To examine the antihypertensive effect of the synthetic analogue of the endogenous nitric oxide donors in patients with grades 2-3 hypertension and uncomplicated hypertensive crisis (HC). The study included 30 male patients aged 35 to 73 years (mean age 55.5 ± 10.8 years). All the patients had grades 2-3 essential or secondary hypertension. Thirteen (43.3%) patients were observed to have signs of HC; 17 (56.7%) patients had persistent blood pressure (BP) elevation. A dinitrosyl iron complex was injected in a dose of 1.5 or 3 mg per kg of body weight. The purpose of its administration was to lower BP by at least 20% of its baseline level. No significant side effects associated with the administration of the test drug were recorded when the clinical trial protocol was implemented. All the patients reported fever and facial hyperemia during and 10-20 minutes after injection. They all (100%) showed efficient blood pressure reduction of at least 20% of the baseline level. Blood pressure changes were similar when the agent was administered in doses of 1.5 or 3 mg/kg. At 6-8 minutes after the drug was injected, there was a maximal decrease in blood pressure, then its gradual rise and stabilization at a lower level than the baseline one within the following 8 hours. There were no significant differences in the magnitude of a blood pressure reduction after administration of 1.5 and 3 mg/kg. The findings suggest that the dinitrosyl iron complex is highly effective in treating uncomplicated HC. The antihypertensive effect of the drug persists for 8 hours after its injection, which is very important during prehospital therapy. The drug is well tolerated by patients and causes an insignificant number of side effects.

Pyronaridine-artesunate is a novel artemisinin-based combination therapy. The efficacy and safety of pyronaridine-artesunate were compared with artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria in children. This phase III open-label randomized controlled non-inferiority trial was conducted in Western Kenya. Children aged 6 months to ≤ 12 years with a bodyweight > 5 kg and microscopically confirmed P. falciparum malaria were randomly assigned in a 1:1 ratio to orally receive pyronaridine-artesunate or artemether-lumefantrine, dosed according to bodyweight, for 3 days. Of 197 participants, 101 received pyronaridine-artesunate and 96 received artemether-lumefantrine. The day-28 adequate clinical and parasitological response in the per-protocol population, PCR-corrected for reinfections, was 98.9% (93/94, 95% CI 94.2-99.8) for pyronaridine-artesunate and 96.4% (81/84, 95% CI 90.0-98.8) for artemether-lumefantrine. Pyronaridine-artesunate was found to be non-inferior to artemether-lumefantrine: the treatment difference was 2.5% (95% CI - 2.8 to 9.0). Adverse events occurred in 41.6% (42/101) and 34.4% (33/96) of patients in the pyronaridine-artesunate group and the artemether-lumefantrine group, respectively. No participants were found to have alanine or aspartate aminotransferase levels > 3 times the upper limit of normal. Pyronaridine-artesunate was well tolerated, efficacious and non-inferior to artemether-lumefantrine for the treatment of uncomplicated P. falciparum malaria in Kenyan children. Results are in line with previous reports and inclusion of pyronaridine-artesunate in paediatric malaria treatment programmes should be considered.

The World Health Organization (WHO) recently recommended the addition of a single low-dose of the gametocytocidal drug primaquine (PQ) to artemisinin-based combination therapy (ACT) in low transmission settings as a component of pre-elimination or elimination programmes. However, it is unclear whether that influences the ACT cure rate. The study assessed treatment outcome of artemether-lumefantrine (AL) plus a single PQ dose (0.25 mg/kg) versus standard AL regimen for treatment of acute uncomplicated Plasmodium falciparum malaria in Tanzania. A randomized, single-blinded, clinical trial was conducted in Yombo, Bagamoyo district, Tanzania. Acute uncomplicated P. falciparum malaria patients aged ≥1 year, with the exception of pregnant and lactating women, were enrolled and treated with AL plus a single PQ dose (0.25 mg/kg) or AL alone under supervision. PQ was administered together with the first AL dose. Clinical and laboratory assessments were performed at 0, 8, 24, 36, 48, 60, and 72 h and on days 7, 14, 21, and 28. The primary end-point was a polymerase chain reaction (PCR)-adjusted adequate clinical and parasitological response (ACPR) on day 28. Secondary outcomes included: fever and asexual parasitaemia clearance, proportion of patients with PCR-determined parasitaemia on day 3, and proportion of patients with Pfmdr1 N86Y and Pfcrt K76T on days 0, 3 and day of recurrent infection. Overall 220 patients were enrolled, 110 were allocated AL + PQ and AL, respectively. Parasite clearance by microscopy was fast, but PCR detectable parasitaemia on day 3 was 31/109 (28.4 %) and 29/108 (26.9 %) in patients treated with AL + PQ and AL, respectively (p = 0.79). Day 28 PCR-adjusted ACPR and re-infection rate was 105/105 (100 %) and 101/102 (99 %) (p = 0.31), and 5/107 (4.7 %) and 5/8 (4.8 %) (p = 0.95), in AL + PQ and AL arm, respectively. There was neither any statistically significant difference in the proportion of Pfmdr1 N86Y or Pfcrt K76T between treatment arms on days 0, 3 and day of recurrent infection, nor within treatment arms between days 0 and 3 or day 0 and day of recurrent infection. The new WHO recommendation of adding a single low-dose of PQ to AL did not compromise treatment outcome of uncomplicated P. falciparum malaria in Tanzania. Trial registration number NCT02090036.

Background Despite the fact that a large proportion of children with fever in Africa present at primary health care facilities, few studies have been designed to specifically study the causes of uncomplicated childhood febrile illness at this level of care, especially in areas like Zanzibar that has recently undergone a dramatic change from high to low malaria transmission. Methods We prospectively studied the aetiology of febrile illness in 677 children aged 2–59 months with acute uncomplicated fever managed by IMCI (Integrated Management of Childhood Illness) guidelines in Zanzibar, using point-of-care tests, urine culture, blood-PCR, chest X-ray (CXR) of IMCI-pneumonia classified patients, and multiple quantitative (q)PCR investigations of nasopharyngeal (NPH) (all patients) and rectal (GE) swabs (diarrhoea patients). For comparison, we also performed NPH and GE qPCR analyses in 167 healthy community controls. Final fever diagnoses were retrospectively established based on all clinical and laboratory data. Clinical outcome was assessed during a 14-day follow-up. The utility of IMCI for identifying infections presumed to require antibiotics was evaluated. Findings NPH-qPCR and GE-qPCR detected ≥1 pathogen in 657/672 (98%) and 153/164 (93%) of patients and 158/166 (95%) and 144/165 (87%) of controls, respectively. Overall, 57% (387/677) had IMCI-pneumonia, but only 12% (42/342) had CXR-confirmed pneumonia. Two patients were positive for Plasmodium falciparum. Respiratory syncytial virus (24.5%), influenza A/B (22.3%), rhinovirus (10.5%) and group-A streptococci (6.4%), CXR-confirmed pneumonia (6.2%), Shigella (4.3%) were the most common viral and bacterial fever diagnoses, respectively. Blood-PCR conducted in a sub-group of patients (n = 83) without defined fever diagnosis was negative for rickettsiae, chikungunya, dengue, Rift Valley fever and West Nile viruses. Antibiotics were prescribed to 500 (74%) patients, but only 152 (22%) had an infection retrospectively considered to require antibiotics. Clinical outcome was generally good. However, two children died. Only 68 (11%) patients remained febrile on day 3 and three of them had verified fever on day 14. An additional 29 (4.5%) children had fever relapse on day 14. Regression analysis determined C-reactive Protein (CRP) as the only independent variable significantly associated with CXR-confirmed pneumonia. Conclusions This is the first study on uncomplicated febrile illness in African children that both applied a comprehensive laboratory panel and a healthy control group. A majority of patients had viral respiratory tract infection. Pathogens were frequently detected by qPCR also in asymptomatic children, demonstrating the importance of incorporating controls in fever aetiology studies. The precision of IMCI for identifying infections requiring antibiotics was low. PMID:26821179

Retrospective audit of antimicrobial prescribing practices for acute exacerbations of chronic obstructive pulmonary diseases in a large regional hospital.

Chronic obstructive pulmonary disease (COPD) is associated with significant morbidity and mortality, and frequent exacerbations are associated with an increased risk of death, deterioration in lung function and reduced quality of life. Current Australian guidelines developed by the Lung Foundation of Australia (the COPD-X Plan) recommends the use of a short course of corticosteroids and oral antibiotics (amoxycillin or doxycycline) as part of the treatment of an AECOPD; however, it was noted that clinical practice at the study hospital had deviated from these guidelines. To evaluate the antibiotic prescribing practices in acute exacerbations of chronic obstructive pulmonary disease (AECOPD) patients, and to compare the differences in clinical outcomes (primarily mean length of stay and the rate of unplanned readmissions) between patients who received broad- vs. narrow-spectrum antibiotics in a large regional hospital. Retrospective audit of medical records for patients admitted with uncomplicated AECOPD during January-September, 2014 in a 224 acute bed regional hospital in Victoria, Australia. Fifty-nine per cent of patients received broad-spectrum antibiotics (ceftriaxone), whereas only 10% of prescriptions were concordant with current Australian guideline recommendations. Patients receiving a broad-spectrum regimen were more likely to be older (74·9 vs. 69·9 years; P = 0·009), have a higher COPD severity score (i.e. BAP-65 score, 1·55 vs. 1·06; P = 0·002) and a higher CRP (59·2 vs. 25·5 mg/L; P = 0·003) on admission. The mean LOS was not significantly different between those who received ceftriaxone and those who did not (5·09 vs. 4·55 days; P = 0·47). There was no significant difference between the groups in rates of readmissions. The antibiotic prescribing patterns for AECOPD in rural and regional Australian hospitals have not previously been examined in the current literature. In the study hospital, the majority of patients received broad-spectrum antibiotics in the initial treatment of AECOPD. No differences in hospital length of stay, or rate of readmission for AECOPD were observed between those who received broad- and narrow-spectrum antibiotics. © 2017 John Wiley & Sons Ltd.

Background The World Health Organization (WHO) recommends Artemisinin-based Combination Therapy (ACT) for treating uncomplicated Plasmodium falciparum malaria. This review aims to assist the decision-making of malaria control programmes by providing an overview of the relative effects of dihydroartemisinin-piperaquine (DHA-P) versus other recommended ACTs. Objectives To evaluate the effectiveness and safety of DHA-P compared to other ACTs for treating uncomplicated P. falciparum malaria in adults and children. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL) published in The Cochrane Library; MEDLINE; EMBASE; LILACS, and the metaRegister of Controlled Trials (mRCT) up to July 2013. Selection criteria Randomized controlled trials comparing a three-day course of DHA-P to a three-day course of an alternative WHO recommended ACT in uncomplicated P. falciparum malaria. Data collection and analysis Two authors independently assessed trials for eligibility and risk of bias, and extracted data. We analysed primary outcomes in line with the WHO 'Protocol for assessing and monitoring antimalarial drug efficacy’ and compared drugs using risk ratios (RR) and 95% confidence intervals (CI). Secondary outcomes were effects on gametocytes, haemoglobin, and adverse events. We assessed the quality of evidence using the GRADE approach. Main results We included 27 trials, enrolling 16,382 adults and children, and conducted between 2002 and 2010. Most trials excluded infants aged less than six months and pregnant women. DHA-P versus artemether-lumefantrine In Africa, over 28 days follow-up, DHA-P is superior to artemether-lumefantrine at preventing further parasitaemia (PCR-unadjusted treatment failure: RR 0.34, 95% CI 0.30 to 0.39, nine trials, 6200 participants, high quality evidence), and although PCR-adjusted treatment failure was below 5% for both ACTs, it was consistently lower with DHA-P (PCR-adjusted treatment failure: RR 0.42, 95% CI 0.29 to 0.62, nine trials, 5417 participants, high quality evidence). DHA-P has a longer prophylactic effect on new infections which may last for up to 63 days (PCR-unadjusted treatment failure: RR 0.71, 95% CI 0.65 to 0.78, two trials, 3200 participants, high quality evidence). In Asia and Oceania, no differences have been shown at day 28 (four trials, 1143 participants, moderate quality evidence), or day 63 (one trial, 323 participants, low quality evidence). Compared to artemether-lumefantrine, no difference was seen in prolonged QTc (low quality evidence), and no cardiac arrhythmias were reported. The frequency of other adverse events is probably similar with both combinations (moderate quality evidence). DHA-P versus artesunate plus mefloquine In Asia, over 28 days follow-up, DHA-P is as effective as artesunate plus mefloquine at preventing further parasitaemia (PCR-unadjusted treatment failure: eight trials, 3487 participants, high quality evidence). Once adjusted by PCR to exclude new infections, treatment failure at day 28 was below 5% for both ACTs in all eight trials, but lower with DHA-P in two trials (PCR-adjusted treatment failure: RR 0.41 95% CI 0.21 to 0.80, eight trials, 3482 participants, high quality evidence). Both combinations contain partner drugs with very long half-lives and no consistent benefit in preventing new infections has been seen over 63 days follow-up (PCR-unadjusted treatment failure: five trials, 2715 participants, moderate quality evidence). In the only trial from South America, there were fewer recurrent parastaemias over 63 days with artesunate plus mefloquine (PCR-unadjusted treatment failure: RR 6.19, 95% CI 1.40 to 27.35, one trial, 445 participants, low quality evidence), but no differences were seen once adjusted for new infections (PCR-adjusted treatment failure: one trial, 435 participants, low quality evidence). DHA-P is associated with less nausea, vomiting, dizziness, sleeplessness, and palpitations compared to artesunate plus mefloquine (moderate quality evidence). DHA-P was associated with more frequent prolongation of the QTc interval (low quality evidence), but no cardiac arrhythmias were reported. Authors' conclusions In Africa, dihydroartemisinin-piperaquine reduces overall treatment failure compared to artemether-lumefantrine, although both drugs have PCR-adjusted failure rates of less than 5%. In Asia, dihydroartemisinin-piperaquine is as effective as artesunate plus mefloquine, and is better tolerated. PLAIN LANGUAGE SUMMARY Dihydroartemisinin-piperaquine for treating uncomplicated malaria This review summarises trials evaluating the effects of dihydroartemisinin-piperaquine (DHA-P) compared to other artemisinin-based combination therapies recommended by the World Health Organization. After searching for relevant trials up to July 2013, we included 27 randomized controlled trials, enrolling 16,382 adults and children and conducted between 2002 and 2010. What is uncomplicated malaria and how might dihydroartemisinin-piperaquine work Uncomplicated malaria is the mild form of malaria which usually causes a fever, with or without headache, tiredness, muscle pains, abdominal pains, nausea, and vomiting. If left untreated, uncomplicated malaria can develop into severe malaria with kidney failure, breathing difficulties, fitting, unconsciousness, and eventually death. DHA-P is one of five artemisinin-based combination therapies the World Health Organization currently recommends to treat malaria. These combinations contain an artemisinin component (such as dihydroartemisinin) which works very quickly to clear the malaria parasite from the person's blood, and a longer acting drug (such as piperaquine) which clears the remaining parasites from the blood and may prevent new infections with malaria for several weeks. What the research says DHA-P versus artemether lumefantrine In studies of people living in Africa, both DHA-P and artemether-lumefantrine are very effective at treating malaria (high quality evidence). However, DHA-P cures slightly more patients than artemether-lumefantrine, and it also prevents further malaria infections for longer after treatment (high quality evidence). DHA-P and artemether-lumefantrine probably have similar side effects (moderate quality evidence). DHA-P versus artesunate plus mefloquine In studies of people living in Asia, DHA-P is as effective as artesunate plus mefloquine at treating malaria (moderate quality evidence). Artesunate plus mefloquine probably causes more nausea, vomiting, dizziness, sleeplessness, and palpitations than DHA-P (moderate quality evidence). Overall, in some people, DHA-P has been seen to cause short term changes in electrocardiographs tracing the conduction of the heart rhythm (low quality evidence), but these small changes on the electrocardiograph resolved within one week without serious consequences.

Epidemiology and microbiology of skin and soft tissue infections.

PubMed

Esposito, Silvano; Noviello, Silvana; Leone, Sebastiano

2016-04-01

Skin and soft tissue infections (SSTIs) are a broad spectrum of diseases, including uncomplicated and complicated infections. Herein, we review the current epidemiology and microbiology of SSTIs. In the last decades, a significant growing trend of SSTIs both in the community and healthcare settings with a dramatic increase of the economic burden for these diagnoses was observed. Several observational studies found that SSTIs are a substantial cause of ambulatory and emergency department visits, and of hospitalizations. Although, microbiology of SSTIs changes according to the clinical feature and the severity of illness, Staphylococcus aureus being the leading cause of both uncomplicated infections and complicated infections. Moreover, the increasing prevalence of infections because of multidrug-resistant bacteria, mainly methicillin-resistant S. aureus (both community-acquired and healthcare-associated methicillin-resistant S. aureus), are associated with significantly increased morbidity, mortality, length of hospital stay, and costs, compared with infections because of susceptible strains. Moreover, although it is unclear whether high vancomycin minimum inhibitory concentration is associated with a worse outcome, it poses a further challenge for the clinicians. The understanding of the current epidemiology and microbiology of SSTIs is indicated for an appropriate antimicrobial therapy and an overall optimal management of SSTIs.

Early physiotherapy ad modum Vojta or Bobath in infants with suspected neuromotor disturbance.

d'Avignon, M; Norén, L; Arman, T

1981-08-01

Thirty children with early signs of cerebral neuromotor disturbances according to "Vojta criteria" were followed until the age of thirty-three months to six years. Twelve children were treated with early physiotherapy according to Bobath, ten children were treated according to Vojta and eight constituted a control group. The infants tended for early physical therapy were divided by random into two different groups. The neonatal risk factors, however, proved to be unevenly distributed among the infants in the Vojta- and the Bobath-treated groups - the latter being more heavily burdened in this respect. Vojta has claimed that his method of early physiotherapy is able to prevent the development of cerebral palsy (cp) of "uncomplicated" (but not of "complicated") type. At follow-up we found one child out of nine with "uncomplicated" cp in the Vojta group against three out of six in the Bobath- and two out of six in the control group. These differences, however, are not statistically significant. Further detailed studies with greater groups of children seem necessary to help us to clarify these problems. The psychological aspects of early physiotherapy should be thoroughly considered and this is particularly important in connection with the Vojta method.

Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF), often used in combinational chemotherapy regimens for the treatment of patients with colorectal liver metastases. However adverse events have been attributed to the use of bevacizumab including gastrointestinal perforations, thrombotic events, hypertension, bleeding, and wound healing complications. 53-year-old male, with a history of colorectal cancer with liver metastasis, receiving a combination of cytotoxic chemotherapy (FOLFIRI, irinotecan with fluorouracil and folinic acid) with bevacizumab presented as an emergency with an incarcerated incisional hernia. The last administration of chemotherapy and bevacizumab had taken place 2 weeks prior to this presentation. As the risk of strangulation of the bowel was increased, a decision was made to take the patient to theatre, although the hazard with respect to wound healing, haemorrhage, and infection risk was high due to the recent administration of chemotherapy with bevacizumab. The patient underwent an open repair of the incarcerated recurrent incisional hernia with placement of a biological mesh, and the postoperative recovery was uncomplicated with no wound healing or bleeding problems.

In severe malaria, intravenous artesunate may cause delayed haemolytic anaemia but there has been little evaluation of the propensity of oral artemisinin-based combination treatments (ACTs) to cause late-appearing anaemia. The frequency of anaemia (haematocrit <30%), and temporal changes in haematocrit were evaluated in 1,191 malarious children following ACTs. "Haematocrit conservation" was evaluated by using the fall in haematocrit/1,000 asexual parasites cleared from the peripheral blood (FIH/1,000 asexual parasites cpb), and the ratio of the average haematocrit (on the first 3 days of starting treatment):total parasitaemia cleared. The frequency of anaemia decreased significantly following treatment. FIH/1,000 asexual parasites cpb, average haematocrit:total parasitaemia cleared, and mean haematocrit 5 weeks after treatment began were significantly lower in hyperparasitaemic children than in children without hyperparasitaemia, suggesting haematocrit conservation during treatment followed later by a loss of haematocrit. Asymptomatic late-appearing anaemia occurred in 6% of the children. Artesunate-amodiaquine and artemether-lumefantrine contribute to haematocrit conservation at high parasitaemias but may cause late-appearing anaemia. © 2017 S. Karger AG, Basel.

OBJECTIVE: This study aims to evaluate colonic transport following colostomy irrigation with a new scintigraphic technique. MATERIALS AND METHODS: To label the bowel contents 19 patients (11 uncomplicated colostomy irrigation, 8 complicated colostomy irrigation) took 111In-labelled polystyrene pellets one and two days before investigation. 99mTc-DTPA was mixed with the irrigation fluid to assess its extent within the bowel. Scintigraphy was performed before and after a standardized washout procedure. The colon was divided into three segments 1: the caecum andascending colon; 2: the transverse colon; 3: the descending and sigmoid colon. Assuming ordered evacuation of the colon, the contribution of each colonic segment to the total evacuation was expressed as a percentage of the original segmental counts. These were added to reach a total defaecation score (range: 0-300). RESULTS: In uncomplicated colostomy irrigation, the median defaecation score was 235 (range: 145-289) corresponding to complete evacuation of the descending and transverse colon and 35% evacuation of the caecum/ascending colon. In complicated colostomy irrigation it was possible to distinguish specific emptying patterns. The retained irrigation fluid reached the caecum in all but one patient. CONCLUSION: Scintigraphy can be used to evaluate colonic emptying following colostomy irrigation.

Diagnostic Value of Vaginal Discharge, Wet Mount and Vaginal pH – An Update on the Basics of Gynecologic Infectiology

Frobenius, W.; Bogdan, C.

2015-01-01

The majority of uncomplicated vulvovaginal complaints (e.g. bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis) can be detected with uncomplicated basic infectiological tests and can usually be treated effectively without requiring further diagnostic procedures. Tests include measurement of vaginal pH, preparation and assessment of wet mount slides prepared from vaginal or cervical discharge, and the correct clinical and microbiological classification of findings. In Germany, at least in recent years, this has not been sufficiently taught or practiced. As new regulations on specialist gynecologic training in Germany are currently being drawn up, this overview provides basic information on gynecologic infectiology and summarizes clinically relevant aspects of recent microbiological findings on the physiology and pathology of vaginal flora. The clinical signs and symptoms of aerobic vaginitis, the pathogenesis of which is still not completely understood, are also reviewed. Finally, the symptoms, indications and risk factors for pelvic inflammatory disease (PID) are presented. In contrast to the above-listed infections, PID requires immediate culture of the pathogen from samples (e.g. obtained by laparoscopy) with microbiological diagnostic procedures carried out by specialist laboratories. A schematic summary of all pathologies discussed here is presented. PMID:26028693

The risk of bowel injury during surgery for small bowel obstruction (SBO) has generated interest in conservative treatment modalities. Few data are available on conservative Gastrografin treatment for SBO in children. We prospectively included patients with uncomplicated adhesive SBO managed at a pediatric center between March 2009 and September 2010. Patients who were unimproved after 48 h of conservative treatment received 50-100 ml of Gastrografin. If Gastrografin was seen in the cecum on the abdominal radiograph 4-6 h later, feeding was initiated and the patient was discharged on the same day. Each patient was matched to 2 controls on the number of previous SBO episodes. The primary outcome was length of hospital stay (>3 days), and the secondary outcome was time from admission to first feed (>2 days). Both were compared in the two groups using conditional logistic regression. The 8 patients admitted for SBO were matched to 16 controls. Gastrografin administration was associated with significantly lower risks of staying in the hospital longer than 3 days (P < 0.10) and waiting more than 2 days before the first feed. This preliminary study suggests that Gastrografin may be useful for managing adhesive SBO in children.

There are few reports on pregnancies in sporadic and familial amyotrophic lateral sclerosis (ALS). We report on a young woman with sporadic ALS who gave birth twice during the course of her disease. The first pregnancy occurred 13 months after the onset of symptoms, and one month after diagnosis. The pregnancy was uncomplicated and resulted in vaginal delivery of a healthy boy. Fifteen months later, when she was already bed-ridden, she became pregnant again. She received a percutaneous endoscopic gastrostomy in the 21st gestational week and underwent early Caesarean section in the 34th week of gestation. The child was ventilated for 72 h in a neonatological unit. The patient was tracheotomized and ventilated two months later, i.e. 47 months after symptom onset, and died nine months later from gastrointestinal haemorrhage. Her two children have developed without abnormalities to date. This case confirms that pregnancies in early-stage ALS can develop normally and may result in uncomplicated vaginal delivery. Pregnancies in late stages may be critical for mother and child, and early delivery by Caesarean section may become necessary although neonatal outcome can be good.

We evaluated the efficacy and effectiveness of mefloquine (MQ) plus artesunate (AS) to treat patients with uncomplicated malaria in the Peruvian Amazon Basin in April 2005–March 2006. Patients ≥ 1 year of age with fever (axillary temperature ≥ 37.5°C) or history of fever and Plasmodium falciparum monoinfection were included. Patients received antimalarial treatment with MQ (12.5 mg/kg/day for two days) and AS (4.0 mg/kg/day for three days) either by directly observed therapy or without directly observed therapy. After a 28-day follow-up, treatment efficacy and effectiveness were assessed on the basis of clinical and parasitologic outcomes. Ninety-six patients were enrolled in each study group; nine patients were lost to follow-up. All patients, except for one in the observed group, demonstrated adequate clinical and parasitologic response; none had detectable parasitemia on day 3. The efficacy of MQ + AS efficacy was 98.9% (95% confidence interval = 94.1–100.0%) and the effectiveness was 100.0% (95% confidence interval = 95.9–100.0%). Our study shows that MQ + AS is highly efficacious in the Peruvian Amazon. PMID:21896825

Colonic diverticular disease. Treatment and prevention.

2015-12-01

Diverticular disease represents the most common disease affecting the colon in the Western world. Most cases remain asymptomatic, but some others will have symptoms or develop complications. The aims of treatment in symptomatic uncomplicated diverticular disease are to prevent complications and reduce the frequency and intensity of symptoms. Fibre, probiotics, mesalazine, rifaximin and their combinations seem to be usually an effective therapy. In the uncomplicated diverticulitis, outpatient management is considered the optimal approach in the majority of patients, and oral antibiotics remain the mainstay of treatment. Admission to hospital and intravenous antibiotic are recommended only when the patient is unable to intake food orally, affected by severe comorbidity or does not improve. However, inpatient management and intravenous antibiotics are necessary in complicated diverticulitis. The role of surgery is also changing. Most diverticulitis-associated abscesses can be treated with antibiotics and/or percutaneous drainage and emergency surgery is considered only in patients with acute peritonitis. Finally, patient related factors, and not the number of recurrences, play the most important role in selecting recipients of elective surgery to avoid recurrences.

2017-01-01

The management of frontal sinus fractures has evolved in the endoscopic era. The development of functional endoscopic sinus surgery (FESS) has been incorporated into management algorithms proposed by otolaryngologists, but the extent of its influence on plastic surgeons and oral and maxillofacial surgeons is heretofore unknown. A cross-sectional survey was performed to assess the practice pattern variations in frontal sinus fracture management across multiple surgical disciplines. A total of 298 surveys were reviewed. 33.5% were facial plastic surgeons with otolaryngology training, 25.8% general otolaryngologists, 25.5% plastic surgeons, and 15.1% oral and maxillofacial surgeons. 74.8% of respondents practiced in an academic setting. 61.7% felt endoscopic sinus surgery changed their management of frontal sinus fractures. 91.8% of respondents favored observation for uncomplicated, nondisplaced frontal sinus outflow tract fractures. 36.4% favored observation and 35.9% favored endoscopic sinus surgery for uncomplicated, displaced frontal sinus outflow tract fractures. For complicated, displaced frontal sinus outflow tract fractures, obliteration was more frequently favored by plastic surgeons and oral and maxillofacial surgeons than those with otolaryngology training. The utility of FESS in managing frontal sinus fractures appears to be recognized across multiple surgical disciplines. PMID:28523084

The aim of our study was to investigate the association between homocysteine and asymmetric dimethylarginine in preeclamptic women with and without intrauterine growth restriction compared with normal healthy uncomplicated pregnancies and normotensive pregnancies complicated by idiopathic isolated intrauterine fetal growth restriction. The maternal serum homocysteine and asymmetric dimethylarginine concentrations were determined using a sandwich enzyme-linked immunosorbent assays. A statistically significant positive correlation of maternal serum homocysteine levels with the serum asymmetric dimethylarginine levels was observed in healthy normotensive uncomplicated pregnant women from the control group and in preeclamptic patients with appropriate-for-gestational-age fetuses (R = 0.380079, p-value = 0.002311* and R = 0.455797, p-value = 0.004030* for the control and the P groups, respectively). However, this correlation was not significant in women with pregnancy complicated by intrauterine growth restriction, both isolated and in the course of severe preeclampsia. These findings provide support for the hypothesis that elevated levels of asymmetric dimethylarginine in pregnancy complicated by preeclampsia are associated with elevated homocysteine levels. But our results also demonstrate that in pregnancies complicated by intrauterine growth restriction, this mechanism is important, although not the only one.

Malaria has remained a major cause of morbidity and mortality among the under-five children in Nigeria. Prompt and accurate diagnosis of malaria is necessary in controlling this high burden and preventing unnecessary use of anti-malarial drugs. Malaria rapid diagnostic test (MRDT) offers the hope of achieving this goal. However, the performance of these kits among the most vulnerable age group to malaria is inadequate. In this cross-sectional study, 433 out-patients, aged <5 years with fever or history of fever were enrolled. Each candidate was tested for malaria parasitaemia using ACON; malaria pf. Thick and thin films were also prepared from the same finger prick blood for each candidate. Malaria rapid diagnostic test had sensitivity of 8.3%, specificity of 100%, positive predictive value (PPV) of 100% and negative predictive value (NPV) of 74%. The sensitivity of MRDT increased with increasing age. This effect of age on sensitivity was statistically significant (P = 0.007). Similarly parasite density had significant effect on the sensitivity of MRDT (P = <0.001). Histidine-rich protein-2 based MRDT is not a reliable mean of diagnosing malaria in the under-five age children with acute uncomplicated malaria.

Abstract Background The appropriate duration of antibiotics for staphylococcal bloodstream infection (BSI) is unknown. An algorithm to identify patients with staphylococcal BSI who can be safely treated with shorter courses of therapy would improve care and reduce total antibiotic use. Methods Adult patients with staphylococcal BSI were randomized to treatment based on algorithm-based therapy (ABT) or to standard of care (SOC). Co-primary outcomes were clinical success, as determined by a blinded Adjudication Committee, and serious adverse event (SAE) rates. The prespecified secondary outcome measure was antibiotic days by treatment group, among patients without complicated BSI. Prespecified durations of therapy in ABT were: S. aureus BSI (SAB): uncomplicated: 14 days; complicated: 4–6 weeks. Coagulase-negative staphylococci BSI (CoNSB): simple (1 positive blood culture) (0–3 days), uncomplicated (>1 positive blood culture) (5 days), complicated (7–28 days). Outcomes were compared using intention-to-treat principles. The target sample size was 500 patients, to ensure 90% power for establishing noninferiority within a margin of 15%. Results Between April 2011 and March 2017, 509 adults with suspected staphylococcal BSI at 16 sites in the US and Spain were randomized to ABT (N = 255) or SOC (N = 254). There were 116 patients with SAB (23%) and 385 (76%) with CoNSB (Figure 1). Overall success rate in the ABT group was 82.0% vs. 81.5% in the SOC group, difference 0.5%, 95% CI −5.2% to 6.1%. SAEs were reported in 32.9% of ABT vs. 28.3% of SOC patients (OR 1.2, 95% CI 0.9 to 1.8). Among evaluable patients without complicated BSI, mean duration of therapy was 4.4 days in the ABT group vs. 6.4 days in the SOC group (difference −2.0 days, 95% CI −3.3 to −-0.7, P = 0.003). Among patients with uncomplicated SAB, treatment durations were similar (15.3 days in ABT vs. 16.3 days in SOC, difference −1 day, 95% CI −3.89 to 1.91, P = 0.497), whereas for uncomplicated CoNSB, duration was shorter in the ABT group (5.3 days in ABT vs. 8.4 days in SOC, difference −3 days, 95% CI −4.87 to −1.34, P < 0.001). Conclusion The use of a treatment algorithm for staphylococcal BSI was associated with significant reductions in duration of antibiotic therapy in patients without complicated BSI, without significant differences in overall success or SAEs.

IMPORTANCE Despite professional recommendations to delay elective colon resection for patients with uncomplicated diverticulitis, early surgery (after <3 preceding episodes) appears to be common. Several factors have been suggested to contribute to early surgery, including increasing numbers of younger patients, a lower threshold to operate laparoscopically, and growing recognition of “smoldering” (or nonrecovering) diverticulitis episodes. However, the relevance of these factors in early surgery has not been well tested, and most prior studies have focused on hospitalizations, missing outpatient events and making it difficult to assess guideline adherence in earlier interventions. OBJECTIVE To describe patterns of episodes of diverticulitis before surgery and factors associated with earlier interventions using inpatient, outpatient, and antibiotic prescription claims. DESIGN, SETTING, AND PARTICIPANTS This investigation was a nationwide retrospective cohort study from January 1, 2009, to December 31, 2012. The dates of the analysis were July 2014 to May 2015. Participants were immunocompetent adult patients (age range, 18-64 years) with incident, uncomplicated diverticulitis. EXPOSURE Elective colectomy for diverticulitis. MAIN OUTCOMES AND MEASURES Inpatient, outpatient, and antibiotic prescription claims for diverticulitis captured in the MarketScan (Truven Health Analytics) databases. RESULTS Of 87 461 immunocompetent patients having at least 1 claim for diverticulitis, 6.4% (n = 5604) underwent a resection. The final study cohort comprised 3054 nonimmunocompromised patients who underwent elective resection for uncomplicated diverticulitis, of whom 55.6% (n = 1699) were male. Before elective surgery, they had a mean (SD) of 1.0 (0.9) inpatient claims, 1.5 (1.5) outpatient claims, and 0.5 (1.2) antibiotic prescription claims related to diverticulitis. Resection occurred after fewer than 3 episodes in 94.9% (2897 of 3054) of patients if counting inpatient claims only, in 80.5% (2459 of 3054) if counting inpatient and outpatient claims only, and in 56.3% (1720 of 3054) if counting all types of claims. Based on all types of claims, patients having surgery after fewer than 3 episodes were of similar mean age compared with patients having delayed surgery (both 47.7 years, P = .91), were less likely to undergo laparoscopy (65.1% [1120 of 1720] vs 70.8% [944 of 1334], P = .001), and had more time between the last 2 episodes preceding surgery (157 vs 96 days, P < .001). Patients with health maintenance organization or capitated insurance plans had lower rates of early surgery (50.1% [247 of 493] vs 57.4% [1429 of 2490], P = .01) than those with other insurance plan types. CONCLUSIONS AND RELEVANCE After considering all types of diverticulitis claims, 56.3% (1720 of 3054) of elective resections for uncomplicated diverticulitis occurred after fewer than 3 episodes. Earlier surgery was not explained by younger age, laparoscopy, time between the last 2 episodes preceding surgery, or financial risk-bearing for patients. In delivering value-added surgical care, factors driving early, elective resection for diverticulitis need to be determined. PMID:26864286

Chronic anovulation, polycystic ovarian morphology and hyperandrogenism are the diagnostic criteria for polycystic ovary syndrome (PCOS). Metabolic disturbances are more common in PCOS women who are prone to develop metabolic syndrome and to present higher levels of some cardiovascular disease risk marker. Oral contraceptives are widely used in PCOS, but conflicting data have been reported regarding their impact on carbohydrate and lipid metabolism on PCOS women. This paper presents a critical evaluation of combined oral contraceptives (COCs) metabolic effect - carbohydrate metabolism and insulin sensitivity, lipid metabolism, haemostasis, body weight, arterial pressure and cardiovascular impact - on PCOS women. Because of the paucity of data on the impact of COCs on cardiovascular and metabolic parameters in PCOS patients, most of there commendations are based on studies involving ovulatory women. The use of low-dose COCs is preferable in PCOS, especially among patients with glucose intolerance, insulin resistance and uncomplicated diabetes mellitus. Although reported as a side effect of COCs, marked weight gain has not been confirmed among users. However, when arterial hypertension or elevated risk for thromboembolism is present, progestogen-only hormonal contraceptives should be used instead of COCs. Regarding dyslipidaemia, COCs reduce low-density lipoprotein and total cholesterol and elevate high-density lipoprotein and triglycerides, and therefore are not recommended for women with high triglycerides levels. The choice of a COC, which alleviates the PCOS-induced hyperandrogenism without significant negative impact on cardiovascular risk, is one of the greatest challenges faced by gynaecologists nowadays.

The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

Purpose  Liver stiffness (LS) has been shown to be of use in chronic liver disease patients but its utility in surgical judgment still needs to be proven. A decision-making approach was applied to evaluate whether LS measurement before surgery of hepatocellular carcinoma (HCC) can be useful in avoiding post-hepatectomy liver failure (PHLF). Materials and Methods  Decision curve analysis (DCA) was applied to 202 HCC patients (2008 - 14) with LS measurement prior to hepatectomy to verify whether the occurrence of PHLF grades B/C should be reduced through a decision-making approach with LS.  Results  Within 90 days of surgery, 4 patients died (2 %) and grades B/C PHLF occurred in 29.7 % of cases. Ascites and/or pleural effusion, treatable with medical therapy, were the most frequent complications. DCA showed that using the "expected utility theory" LS measurement can reduce up to 39 % of cases of PHLF without the exclusion of any patient from surgery that duly undergoes an uncomplicated postoperative course. LS measurement does not add any information to normal clinical judgment for patients with a low (< 10 %) risk of PHLF. Conclusion  LS measurement can determine a reduction of PHLF under "expected utility theory" fulfilment. However, the degree of PHLF can be minor and "risk seeking" individuals can accept such a risk on the basis of surgical benefits. © Georg Thieme Verlag KG Stuttgart · New York.

We aimed to assess the impact of a booklet integrating the biopsychosocial model of chronic pain management on reducing disability among patients undergoing lumbar discetomy. In a prospective, controlled, time-series study with an alternate-month design, we enrolled 129 patients from a tertiary care university hospital after they underwent uncomplicated lumbar discectomy for the first time. The intervention group received the biopsychosocial evidence-based booklet and the control group a biomedical-based booklet; the booklets differed only in information content. Patients were blinded to treatment group. The main outcome was disability at 2 months (measured by the Quebec back-pain disability scale [QBPDS]). Secondary outcomes were fear and avoidance beliefs measured by the Fear-Avoidance Beliefs Questionnaire (FABQ). All data were collected by self-reporting questionnaires. At 2 months, disability did not differ between the 2 groups (QBPDS score 32.4±22.8 vs 36.1±18.7, P=0.36). FABQ physical activity score was lower with the evidenced-based booklet as compared with controls (8.0±7.14 vs 11.2±6.3, P=0.008). Providing an evidence-based booklet had no effect at 2 months after surgery on disability but reduced fear-avoidance beliefs about physical activity. This booklet could be an effective tool for health care professionals in helping with patient education. CLINICALTRIALS. NCT00761111. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

OBJECTIVES This study sought to demonstrate transcatheter deployment of a circumferential device within the pericardial space to modify tricuspid annular dimensions interactively and to reduce functional tricuspid regurgitation (TR) in swine. BACKGROUND Functional TR is common and is associated with increased morbidity and mortality. There are no reported transcatheter tricuspid valve repairs. We describe a transcatheter extracardiac tricuspid annuloplasty device positioned in the pericardial space and delivered by puncture through the right atrial appendage. We demonstrate acute and chronic feasibility in swine. METHODS Transatrial intrapericardial tricuspid annuloplasty (TRAIPTA) was performed in 16 Yorkshire swine, including 4 with functional TR. Invasive hemodynamics and cardiac magnetic resonance imaging (MRI) were performed at baseline, immediately after annuloplasty and at follow-up. RESULTS Pericardial access via a right atrial appendage puncture was uncomplicated. In 9 naïve animals, tricuspid septal-lateral and anteroposterior dimensions, the annular area and perimeter, were reduced by 49%, 31%, 59%, and 24% (p < 0.001), respectively. Tricuspid leaflet coaptation length was increased by 53% (p < 0.001). Tricuspid geometric changes were maintained after 9.7 days (range, 7 to 14 days). Small effusions (mean, 46 ml) were observed immediately post-procedure but resolved completely at follow-up. In 4 animals with functional TR, severity of regurgitation by intracardiac echocardiography was reduced. CONCLUSIONS Transatrial intrapericardial tricuspid annuloplasty is a transcatheter extracardiac tricuspid valve repair performed by exiting the heart from within via a transatrial puncture. The geometry of the tricuspid annulus can interactively be modified to reduce severity of functional TR in an animal model. PMID:25703872

In the United States there is debate regarding the appropriate first test for new-onset renal colic, with non-contrast helical computed tomography (CT) receiving the highest ratings from both Agency for Healthcare Research and Quality and the American Urological Association. This is based not only on its accuracy for the diagnosis of renal colic, but also its ability to diagnose other surgical emergencies, which have been thought to occur in 10-15% of patients with suspected renal colic, based on previous studies. In younger patients, it may be reasonable to attempt to avoid immediate CT if concern for dangerous alternative diagnosis is low, based on the risks of radiation from CTs, and particularly in light of evidence that patients with renal colic have a very high likelihood of having multiple CTs in their lifetimes. The objective is to determine the proportion of patients with a dangerous alternative diagnosis in adult patients age 50 and under presenting with uncomplicated (non-infected) suspected renal colic, and also to determine what proportion of these patients undergo emergent urologic intervention. Retrospective chart review of 12 months of patients age 18-50 presenting with "flank pain," excluding patients with end stage renal disease, urinary tract infection, pregnancy and trauma. Dangerous alternative diagnosis was determined by CT. Two hundred and ninety-one patients met inclusion criteria. One hundred and fifteen patients had renal protocol CTs, and zero alternative emergent or urgent diagnoses were identified (one-sided 95% CI [0-2.7%]). Of the 291 encounters, there were 7 urologic procedures performed upon first admission (2.4%, 95% CI [1.0-4.9%]). The prevalence of kidney stone by final diagnosis was 58.8%. This small sample suggests that in younger patients with uncomplicated renal colic, the benefit of immediate CT for suspected renal colic should be questioned. Further studies are needed to determine which patients benefit from immediate CT for suspected renal colic, and which patients could undergo alternate imaging such as ultrasound.

Small pigtail catheters appear to work as well as the traditional large-bore chest tubes in patients with traumatic pneumothorax, but it is not known whether the smaller pigtail catheters are associated with less tube-site pain. This study was conducted to compare tube-site pain following pigtail catheter or chest tube insertion in patients with uncomplicated traumatic pneumothorax. This prospective randomized trial compared 14-Fr pigtail catheters and 28-Fr chest tubes in patients with traumatic pneumothorax presenting to a level I trauma centre from July 2010 to February 2012. Patients who required emergency tube placement, those who refused and those who could not respond to pain assessment were excluded. Primary outcomes were tube-site pain, as assessed by a numerical rating scale, and total pain medication use. Secondary outcomes included the success rate of pneumothorax resolution and insertion-related complications. Forty patients were enrolled. Baseline characteristics of 20 patients in the pigtail catheter group were similar to those of 20 patients in the chest tube group. No patient had a flail chest or haemothorax. Pain scores related to chest wall trauma were similar in the two groups. Patients with a pigtail catheter had significantly lower mean(s.d.) tube-site pain scores than those with a chest tube, at baseline after tube insertion (3.2(0.6) versus 7.7(0.6); P < 0.001), on day 1 (1.9(0.5) versus 6.2(0.7); P < 0.001) and day 2 (2.1(1.1) versus 5.5(1.0); P = 0.040). The decreased use of pain medication associated with pigtail catheter was not significantly different. The duration of tube insertion, success rate and insertion-related complications were all similar in the two groups. For patients with a simple, uncomplicated traumatic pneumothorax, use of a 14-Fr pigtail catheter is associated with reduced pain at the site of insertion, with no other clinically important differences noted compared with chest tubes.

Anecdotal evidence suggests that complex congenital genitourinary anomalies are occurring less frequently. However, few epidemiological studies are available to confirm or refute this suggestion. The Kids' Inpatient Database (KID) is a national, all payer database of several million inpatient pediatric hospitalizations per year, including complicated and uncomplicated in-hospital births. We reviewed the 1997 to 2009 KID to determine the birth prevalence of spina bifida, posterior urethral valves, bladder exstrophy, epispadias, prune belly syndrome, ambiguous genitalia and imperforate anus. For posterior urethral valves and prune belly syndrome we limited our search to newborn males only. During the study period, there was a diagnosis of spina bifida in 3,413 neonates, bladder exstrophy in 214, epispadias in 1,127, ambiguous genitalia in 726, prune belly syndrome in 180, posterior urethral valves in 578 and imperforate anus in 4,040. We identified no significant change in the birth prevalence of spina bifida (from 33.9 new spina bifida births of 100,000 uncomplicated births to 29.0/100,000, p = 0.08), posterior urethral valves (from 10.4/100,000 to 11.0/100,000, p = 0.51), prune belly syndrome (from 4.8/100,000 to 3.3/100,000, p = 0.44) or ambiguous genitalia (from 5.82/100,000 to 5.87/100,000, p = 0.38). There was a significant decrease in the birth prevalence of bladder exstrophy (from 2.4/100,000 to 1.6/100,000 uncomplicated births, p = 0.01) and a significant increase in epispadias (from 8.0/100,000 to 11.6/100,000) and imperforate anus (from 33.6/100,000 to 35.0/100,000, each p = 0.04) during the study period. The birth prevalence of spina bifida, posterior urethral valves and prune belly syndrome appears to have been stable in the last 12 years. Epispadias, ambiguous genitalia and imperforate anus diagnoses in newborns became more common in the same period, while bladder exstrophy diagnoses became less common.

Home-management of malaria (HMM) strategy improves early access of anti-malarial medicines to high-risk groups in remote areas of sub-Saharan Africa. However, limited data are available on the effectiveness of using artemisinin-based combination therapy (ACT) within the HMM strategy. The aim of this study was to assess the effectiveness of artemether-lumefantrine (AL), presently the most favoured ACT in Africa, in under-five children with uncomplicated Plasmodium falciparum malaria in Tanzania, when provided by community health workers (CHWs) and administered unsupervised by parents or guardians at home. An open label, single arm prospective study was conducted in two rural villages with high malaria transmission in Kibaha District, Tanzania. Children presenting to CHWs with uncomplicated fever and a positive rapid malaria diagnostic test (RDT) were provisionally enrolled and provided AL for unsupervised treatment at home. Patients with microscopy confirmed P. falciparum parasitaemia were definitely enrolled and reviewed weekly by the CHWs during 42 days. Primary outcome measure was PCR corrected parasitological cure rate by day 42, as estimated by Kaplan-Meier survival analysis. This trial is registered with ClinicalTrials.gov, number NCT00454961. A total of 244 febrile children were enrolled between March-August 2007. Two patients were lost to follow up on day 14, and one patient withdrew consent on day 21. Some 141/241 (58.5%) patients had recurrent infection during follow-up, of whom 14 had recrudescence. The PCR corrected cure rate by day 42 was 93.0% (95% CI 88.3%-95.9%). The median lumefantrine concentration was statistically significantly lower in patients with recrudescence (97 ng/mL [IQR 0-234]; n = 10) compared with reinfections (205 ng/mL [114-390]; n = 92), or no parasite reappearance (217 [121-374] ng/mL; n = 70; p ≤ 0.046). Provision of AL by CHWs for unsupervised malaria treatment at home was highly effective, which provides evidence base for scaling-up implementation of HMM with AL in Tanzania.

Studies of experimental diabetes mellitus (DM) suggest that increased nitric oxide (NO) bioactivity contributes to renal hyperfiltration. However, the role of NO in mediating hyperfiltration has not been fully elucidated in humans. Our aim was to examine the effect of NO synthase inhibition on renal and peripheral vascular function in normotensive subjects with uncomplicated type 1 DM. Renal function and brachial artery flow-mediated vasodilatation (FMD) were measured before and after an intravenous infusion of the NO synthase inhibitor NG-nitro-l-arginine methyl ester (l-NMMA) in 21 healthy control and 37 type 1 DM patients. Measurements in DM participants were made under clamped euglycemic conditions. The effect of l-NMMA on circulating and urinary NO metabolites (NOx) and cGMP and on urinary prostanoids was also determined. Baseline characteristics were similar in the two groups. For analysis, the DM patients were divided into those with hyperfiltration (DM-H, n = 18) and normal glomerular filtration rate (GFR) levels (DM-N, n = 19). Baseline urine NOx and cGMP were highest in DM-H. l-NMMA led to a decline in GFR in DM-H (152 ± 16 to 140 ± 11 ml·min−1·1.73 m−2) but not DM-N or healthy control participants. The decline in effective renal plasma flow in response to l-NMMA (806 ± 112 to 539 ± 80 ml·min−1·1.73 m−2) in DM-H was also exaggerated compared with the other groups (repeated measures ANOVA, P < 0.05), along with declines in urinary NOx metabolites and cGMP. Baseline FMD was lowest in DM-H compared with the other groups and did not change in response to l-NMMA. l-NMMA reduced FMD and plasma markers of NO bioactivity in the healthy control and DM-N groups. In patients with uncomplicated type 1 DM, renal hyperfiltration is associated with increased NO bioactivity in the kidney and reduced NO bioactivity in the systemic circulation, suggesting a paradoxical state of high renal and low systemic vascular NO bioactivity.

The Bangladeshi national treatment guidelines for uncomplicated malaria follow WHO recommendations but without G6PD testing prior to primaquine administration. A prospective observational study was conducted to assess the efficacy of the current antimalarial policy. Patients with uncomplicated malaria, confirmed by microscopy, attending a health care facility in the Chittagong Hill Tracts, Bangladesh, were treated with artemether-lumefantrine (days 0-2) plus single dose primaquine (0.75mg/kg on day2) for P. falciparum infections, or with chloroquine (days 0-2) plus 14 days primaquine (3.5mg/kg total over 14 days) for P. vivax infections. Hb was measured on days 0, 2 and 9 in all patients and also on days 16 and 30 in patients with P. vivax infection. Participants were followed for 30 days. The study was registered with the clinical trials website (NCT02389374). Between September 2014 and February 2015 a total of 181 patients were enrolled (64% P. falciparum, 30% P. vivax and 6% mixed infections). Median parasite clearance times were 22.0 (Interquartile Range, IQR: 15.2-27.3) hours for P. falciparum, 20.0 (IQR: 9.5-22.7) hours for P. vivax and 16.6 (IQR: 10.0-46.0) hours for mixed infections. All participants were afebrile within 48 hours, two patients with P. falciparum infection remained parasitemic at 48 hours. No patient had recurrent parasitaemia within 30 days. Adjusted male median G6PD activity was 7.82U/gHb. One male participant (1/174) had severe G6PD deficiency (<10% activity), five participants (5/174) had mild G6PD deficiency (10-60% activity). The Hb nadir occurred on day 2 prior to primaquine treatment in P. falciparum and P. vivax infected patients; mean fractional fall in Hb was -8.8% (95%CI -6.7% to -11.0%) and -7.4% (95%CI: -4.5 to -10.4%) respectively. The current antimalarial policy remains effective. The prevalence of G6PD deficiency was low. Main contribution to haemolysis in G6PD normal individuals was attributable to acute malaria rather than primaquine administration. ClinicalTrials.gov NCT02389374.

As per the WHO recommendation, the development of resistance by P. falciparum to most artemisinin combination therapies (ACTs) triggered the need for routine monitoring of the efficacy of the drugs every two years in all malaria endemic countries. Hence, this study was carried out to assess the therapeutic efficacy of Artemether-Lumefantrine (Coartem®) in treating the uncomplicated falciparum malaria, after 9 years of its introduction in the Metehara, Eastern Ethiopia. This is part of the therapeutic efficacy studies by the Federal Ministry of Health Ethiopia, which were conducted in regionally representative sentinel sites in the country from October 2014 to January 2015. Based on the study criteria set by WHO, febrile and malaria suspected outpatients in the health center were consecutively recruited to study. A standard six-dose regimen of AL was administered over three days and followed up for measuring therapeutic responses over 28 days. Data entry and analysis was done by using the WHO designed Excel spreadsheet and SPSS version 20 for Windows. Statistical significant was considered for P-value less than 0.05. Of the 91 patients enrolled, the day-28 analysis showed 83 adequate clinical and parasitological responses (ACPRs). Per protocol analysis, PCR-uncorrected & corrected cure rates of Coartem® among the study participants were 97.6% (95%CI: 93.6-99.5) and 98.8% (CI: 93.5-100%), respectively. No parasite detected on day 3 and onwards. Fever clearance was above 91% on day-3. Mean hemoglobin was significantly increased (P<0.000) from 12.39 g/dl at day 0 to 13.45 g/dl on day 28. No serious adverse drug reactions were observed among the study participants. This study showed high efficacy of AL in the study area, which suggests the continuation of AL as first line drug for the treatment of uncomplicated P. falciparum malaria in the study area. This study recommends further studies on drug toxicity, particularly on repeated cough and oral ulceration.

Cytokine-mediated endothelial activation pathway is a known mechanism of pathogenesis employed by Plasmodium falciparum to induce severe disease symptoms in human host. Though considered benign, complicated cases of Plasmodium vivax are being reported worldwide and from Pakistan. It has been hypothesized that P.vivax utilizes similar mechanism of pathogenesis, as that of P.falciparum for manifestations of severe malaria. Therefore, the main objective of this study was to characterize the role of cytokines and endothelial activation markers in complicated Plasmodium vivax isolates from Pakistan. A case control study using plasma samples from well-characterized groups suffering from P.vivax infection including uncomplicated cases (n=100), complicated cases (n=82) and healthy controls (n=100) were investigated. Base line levels of Tumor necrosis factor-α (TNF-α), Interleukin-6 (IL-6), Interleukin-10 (IL-10), Intercellular adhesion molecule-1 (ICAM-1), Vascular adhesion molecule-1(VCAM-1) and E-selectin were measured by ELISA. Correlation of cytokines and endothelial activation markers was done using Spearman's correlation analysis. Furthermore, significance of these biomarkers as indicators of disease severity was also analyzed. The results showed that TNF-α, IL-10, ICAM-1and VCAM-1 were 3-fold, 3.7 fold and 2 fold increased between uncomplicated and complicated cases. Comparison of healthy controls with uncomplicated cases showed no significant difference in TNF-α concentrations while IL-6, IL-10, ICAM-1, VCAM-1 and E-selectin were found to be elevated respectively. In addition, significant positive correlation was observed between TNF-α and IL-10/ ICAM-1, IL-6 and IL-10, ICAM-1 and VCAM-1.A Receiver operating curve (ROC) was generated which showed that TNF-α, IL-10, ICAM-1 and VCAM-1 were the best individual predictors of complicated P.vivax malaria. The results suggest that though endothelial adhesion molecules are inducible by pro-inflammatory cytokine TNF-α, however, cytokine-mediated endothelial activation pathway is not clearly demonstrated as a mechanism of pathogenesis in complicated P.vivax malaria cases from Pakistan.

Uncomplicated recurrent urinary tract infections (rUTIs) associated with uropathogenic Escherichia coli (UPEC) are common among healthy, reproductive-aged women. Provoked vestibulodynia (PVD) is a major reason of sexual pain in premenopausal women. The aim of this paper is to assess prevalence and predictors of secondary PVD in a cohort of Caucasian-European, heterosexual, sexually active, reproductive-aged women seeking medical help for rUTIs as their primary complaint. Clinical and psychometric variables for 60 consecutive patients with rUTIs were considered. Patients were assessed with a thorough medical and sexual history, a number of psychometric instruments, and a specific physical examination. Urinalysis and self-collected urine cultures from the previous 12 months were also examined. Descriptive statistics and logistic regression models were used to test the associations between secondary PVD and sociodemographic and clinical variables. Mean age was 34.2 years (median 33 years; range 21-42). Secondary PVD was found in 36 of 60 patients (60%). Women with PVD had a higher prevalence of urinary tract infections (UTIs) over the previous 12 months (χ(2) : 4.54; P = 0.03) and suffered more frequently from UPEC-related rUTIs (χ(2) : 5.92; P = 0.01) than those without PVD. Moreover, women with PVD showed significantly lower scores on Female Sexual Function Index domains (all P ≤ 0.01), as compared with PVD-negative women. UPEC-related rUTIs (odds ratio [OR]: 3.1; P = 0.01), six or more UTIs over the previous 12 months (OR: 2.8; P = 0.01), and treatment with three or more antibiotics throughout the same period (OR: 2.1; P = 0.04) emerged as independent predictors of PVD. Three of five Caucasian-European, heterosexual, sexually active women of reproductive age complaining of rUTIs as their primary disorder also suffer from secondary PVD. Uncomplicated UPEC-related rUTIs are more frequently associated with secondary PVD than are UTIs caused by different uropathogens. © 2013 International Society for Sexual Medicine.

Children represent a high-risk group for malaria worldwide. Among people in Thailand who have malaria during childhood, some may have multiple malaria attacks during their lifetime. Malaria may affect neurological cognition in children, resulting in short-term impairment of memory and language functions. However, little is known regarding the long-term effects of malaria infection on cognitive function. This study examines the long-term impact of malaria infection on school performance among school children living in a malaria-endemic area along the Thai-Myanmar border. A retrospective cohort study was conducted among school children aged 6-17 years in a primary-secondary school of a sub-district of Ratchaburi Province, Thailand. History of childhood malaria infection was obtained from the medical records of the sole malaria clinic in the area. School performance was assessed by using scores for the subjects Thai Language and Mathematics in 2014. Other variables, such as demographic characteristics, perinatal history, nutritional status, and emotional intelligence, were also documented. A total of 457 students were included, 135 (30 %) of whom had a history of uncomplicated malaria infection. About half of the malaria-infected children had suffered infection before the age of four years. The mean scores for both Mathematics and Thai Language decreased in relation to the increasing number of malaria attacks. Most students had their last malaria episode more than two years previously. The mean scores were not associated with duration since the last malaria attack. The association between malaria infection and school performance was not significant after adjusting for potential confounders, including gender, school absenteeism over a semester term, and emotional intelligence. This study characterizes the long-term consequences of uncomplicated malaria disease during childhood. School performance was not associated with a history of malaria infection, considering that most students had their last malaria infection more than two years previously. These findings indicate that the impact of uncomplicated malaria infection on school performance may not be prolonged.

Urinary tract infections (UTIs) are the most common bacterial infection in women. Most UTIs are acute uncomplicated cystitis caused by Escherichia coli (86%). This study was undertaken to assess the effectiveness of an association of a cranberry dry extract, D-mannose, a gelling complex composed of the exopolysaccharides produced by Streptococcus thermophilus ST10 (DSM 25246) and tara gum, as well as the 2 microorganisms Lactobacillus plantarum LP01 (LMG P-21021) and Lactobacillus paracasei LPC09 (DSM 24243) in women affected by acute uncomplicated cystitis. Thirty-three premenopausal, nonpregnant women diagnosed with acute uncomplicated cystitis were enrolled in a pilot prospective study and completed the treatment protocol. Subjects were instructed to take 2 doses per day during the first month, and then to continue with 1 sachet per day until the sixtieth day. Nitrites and leukocyte esterase on urine dipstick testing were used as indicators of cystitis, with analysis performed at enrollment, after 30 and 60 days, and after 1 month of follow-up. Typical UTI symptoms, namely dysuria, frequent voiding of small volumes, urinary urgency, suprapubic pain, and gross hematuria were scored 0 to 3 and evaluated at each visit. Positive results for the presence of nitrites and leukocyte esterase were found in 14 and 20 subjects after 30 days and in 9 and 14 women after 60 days, respectively (P<0.001). At the end of the follow-up period, positive results for nitrites and leukocyte esterase were recorded in only 4 and 3 of 24 and 19 subjects (16.7%, P=0.103; 15.8%, P=0.325, respectively), with negative results after 60 days. Typical symptoms of cystitis, specifically dysuria, frequent voiding, urgency, and suprapubic pain were significantly improved as well. No significant differences were recorded in the incidence and severity of hematuria at any visit. The long-term ability of an association of cranberry, D-mannose, an innovative gelling complex, and the 2 microorganisms tested to significantly improve the uncomfortable symptoms reported by women with acute cystitis has been suggested.

To see if radial mean arterial pressure reliably reflects femoral mean arterial pressure in uncomplicated pediatric cardiac surgery. An ethics committee-approved prospective interventional study. Operating room of a tertiary care hospital. Forty-five children aged 3 months to 4 years who underwent pediatric cardiac surgery with hypothermic cardiopulmonary bypass. Simultaneous femoral and radial arterial pressures were recorded at 10-minute intervals intraoperatively. A pressure gradient>5mmHg was considered to be clinically significant. The patients' mean age was 14±11 months and and mean weight was 8.0±3.0kg. A total of 1,816 simultaneous measurements of arterial pressure from the radial and femoral arteries were recorded during the pre-cardiopulmonary bypass, cardiopulmonary bypass, and post-cardiopulmonary bypass periods, including 520 (29%) systolic arterial pressures, 520 (29%) diastolic arterial pressures, and 776 (43%) mean arterial pressures. The paired mean arterial pressure measurements across the 3 periods were significantly and strongly correlated, and this was true for systolic arterial pressures and diastolic arterial pressures as well (r>0.93 and p<0.001 for all). Bland-Altman plots demonstrated good agreement between femoral and radial mean arterial pressures during the pre-cardiopulmonary bypass, cardiopulmonary bypass, and post-cardiopulmonary bypass periods. A significant radial-to-femoral pressure gradient was observed in 150 (8%) of the total 1,816 measurements. These gradients occurred most frequently between pairs of systolic arterial pressure measurements (n = 113, 22% of all systolic arterial pressures), followed by mean arterial pressure measurements (n = 28, 4% of all mean arterial pressures) and diastolic arterial pressures measurements (n = 9, 2% of all diastolic arterial pressures). These significant gradients were not sustained (ie, were not recorded at 2 or more successive time points). The results suggested that radial mean arterial pressure provided an accurate estimate of central mean arterial pressure in uncomplicated pediatric cardiac surgery. There was a significant gradient between radial and femoral mean arterial pressure measurements in only 4% of the mean arterial pressure measurements, and these significant gradients were not sustained.

A Single Drop of 0.5% Proparacaine Hydrochloride for Uncomplicated Clear Corneal Phacoemulsification

PubMed Central

Joshi, Rajesh Subhash

2013-01-01

Purpose: The purpose of this study was to compare the efficacy of a single drop of 0.5% proparacaine hydrochloride in uncomplicated cataract surgery with phacoemulsification. Materials and Methods: Two hundred and ninety five patients scheduled for the phacoemulsification were divided into 2 groups based on the anesthetic agents they were to receive: 146 patients who received a single drop of 0.5% proparacaine 2 min before the start of the surgery (proparacaine group) and; 149 patients who received supplementation of 0.5% intracameral preservative free xylocaine (xylocaine group). A single surgeon performed all surgeries. Intraoperative and post-operative pain scores were evaluated on a visual analog scale. The surgeon noted his subjective impression of corneal clarity, discomfort while performing the surgery any supplemental anesthesia required and intraoperative complications. An anesthetist noted vital parameters and the need for intravenous sedation. Total surgical time was noted. Comparison of parameters was performed with the Chi-square test, and A P value less than 0.05 was considered as statistically significant. Results: No statistically significant difference was seen in the intraoperative (P = 0.24) and post-operative (P = 0.164) pain scores between groups. There was no pain (0 score) in 41.8% of patients in the proparacaine group and 46.3% of patients in the xylocaine group. The average surgical time (P = 0.279) and surgeon discomfort (P = 0.07) were not statistically significantly different between groups. No patients required supplemental anesthesia. There were no surgical complications that could compromise the visual outcome. An equal number of patients in both groups preferred same type of anesthetic technique for the fellow eye cataract surgery (89.11% for the proparacaine group and 90.18% for the xylocaine group). No patients in either group had changes in vital parameters or required intravenous sedation. Conclusion: A single drop pre-operatively, of proparacaine hydrochloride was comparable to the intracameral supplementation of preservative free xylocaine for phacoemulsification in uncomplicated cataract surgery without compromising the visual outcome. However, we recommend individualizing the anesthetic technique according to the requirements of the surgeon. PMID:24014985

To determine the antihypertensive drug prescribing pattern by primary care physicians in patients with uncomplicated essential hypertension; to identify whether such pattern of prescription is appropriate and in accordance with international guidelines for pharmacotherapy of hypertension; and to estimate the impact of such prescriptions on cost of treatment. A prescription-based survey among patients with uncomplicated essential hypertension was conducted in seven out of a total of 18 health centres in Bahrain. The relevant data for our study was collected using cards, designed for chronically-ill patients. A total of 1019 male and 1395 female (62.9%) out of 3838 of the study population were on monotherapy, whereas 596 male and 828 female (37.1%) were on antihypertensive combination therapy. Among the monotherapy category, the various antihypertensive drugs used were as follows: beta-blockers (58.8%), angiotensin converting enzyme (ACE) inhibitors (14.2%), calcium channel blockers (11.1%), diuretics (8.1%) and alpha-methyldopa (7.0%). With respect to overall utilization pattern, beta-blockers were the most frequently prescribed (65.5%), diuretics ranked second (27.4%), followed by ACE inhibitors (20.6%), calcium channel blockers (19.9%) and alpha-methyldopa (8.5%). Within each class of antihypertensives used, the most frequently used individual agents were as follows: (a) among beta-blockers 97.7% used atenolol; (b) among the diuretics, indapamide (35.4%), hydrochlorothiazide (HCTZ) (32.7%), HCTZ in combination with triamterene (25.7%), and chlorthalidone (4.6%); (c) among the ACE inhibitors, captopril (44.9%), enalapril (29.7%), and lisinopril (19.0%); (d) among the calcium channel blockers, nifedipine (98.2%). Significant age- and gender-related differences in prescribing patterns were seen. Short-acting nifedipine monotherapy was inappropriately prescribed in a significant number of patients above the age of 50 years. ACE inhibitors accounted for approximately two-thirds of the total antihypertensive drug expenditure, although these drugs represent only one-fifth of overall antihypertensives used. There is a trend towards excessive use of expensive thiazide-like diuretics such as indapamide which seems to be unjustifiable practice, particularly in a study population free from diabetic hypertensive patients. The general pattern of antihypertensive utilization appears to be in accordance with the guidelines of WHO and the Joint National Committee issued in the 1990s. The trends of prescribing of antihypertensives were in favour of conventional ones such as the beta blockers and diuretics, and the introduction of newer classes of antihypertensives had a generally minimal impact on the prescribing profile. Almost two-thirds of the patients were treated with monotherapy. A disproportionately large percentage of antihypertensive drug cost was due to overt use of ACE inhibitors, and indapamide, instead of thiazide diuretics. The use of short-acting calcium channel blockers especially in the elderly is unjustifiable.

Patients undergoing thyroidectomy often complain aerodigestive disorders. In a previous study we showed the associations between voice impairment and proximal acid reflux, swallowing impairment and Upper Esophageal Sphyncter (UES) incoordination and the decrease in UES pressure in thirty-six patients observed before and soon afterwards uncomplicated thyroidectomy. This study investigated the state of post-thyroidectomy esophageal motility changes and its associations with these disorders after 18-24 months. The thirty-six patients prospectively recruited according to selection criteria (thyroid volume ≤60 ml, benign disease, age 18-65 years, previous neck surgery, thyroiditis, pre- or postoperative vocal cord palsy) underwent voice (VIS) and swallowing (SIS) impairment scores, esophageal manometry and pH monitoring once again. After 18-24 months, both VIS and SIS recovered (respectively: p=0,022; p=0,0001); UES pressure increased (p=0,0001) nearing the preoperative values. The persistence of swallowing complaints were associated with the persistence of esophageal incoordination (p=0,03); the association between voice impairment and proximal acid reflux was confirmed (p<0,001). Our study confirms that aerodigestive disorders after uncomplicated thyroidectomy, largely transient, are strictly connected with upper esophageal motility changes. In this viewpoint, the innervation of upper aerodigestive anatomical structures (larynx, pharynx, upper esophagus) and its variations should be focused.

Recurrent Fever in Children

Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time. PMID:27023528

The free delivery and caesarean policy in Morocco: how much do households still pay?

The Free Deliveries and Caesarean Policy (FDCP) entitles all women in Morocco to deliver free of charge within public hospitals. This study assesses the policy's effectiveness by analysing household expenditures related to childbirth, by delivery type and quintile. Structured exit survey of 973 women in six provinces at five provincial hospitals, two regional hospitals, two university hospitals and three primary health centres with maternity units. Households reported spending a median of US$ 59 in total for costs inside and outside of hospitals. Women requiring caesareans payed more than women with uncomplicated deliveries (P < 0.0001). The median cost was US$45 for a uncomplicated delivery, US$50 for a complicated delivery and US$65 for a caesarean section. The prescription given upon exiting the hospital comprised 62% of the total costs. Eighty-eight per cent of women from the poorest quintiles faced catastrophic expenditures. The women's perception of their hospital stay and the FDCP policy was overwhelmingly positive, but differences were noted at the various sites. The policy has been largely but not fully effective in removing financial barriers for delivery care in Morocco. More progress should also be made on increasing awareness of the policy and on easing the financial burden, which is still borne by households with lower incomes. © 2015 John Wiley & Sons Ltd.

An uncomplicated cystitis caused by CO2-dependent Proteus mirabilis was observed in a 64-year-old Japanese female patient with Sjögren's syndrome in the Aomori Kyoritsu Hospital, Aomori, Japan. The initial P. mirabilis isolate came from a midstream urine specimen containing large numbers of Gram-negative, rod-shaped organisms that failed to grow on both Drigalski agar and sheep blood agar incubated in ambient air. The organism did grow when the urine was cultured overnight on blood agar under anaerobic conditions. Hence, we believed that the organism was an anaerobe. Further investigation revealed that the isolate grew on sheep blood agar along with swarming when the atmospheric CO2 concentrations were increased to 5%. Initially, we failed to characterize or identify the P. mirabilis isolate or determine its antimicrobial susceptibilities using the MicroScan WalkAway-40 System because the isolate did not grow in the system. However, the isolate was subsequently identified as P. mirabilis based on its morphological, cultural, and biochemical properties by using the commercially available kit systems, Quick ID-GN and ID-Test EB-20. This identification of the isolate was confirmed by sequencing the 16S rRNA gene of the organism. To our knowledge, this is the first clinical isolation of capnophilic P. mirabilis.

Abdominal gas gangrene caused by clostridia species is rare and usually associated with organ perforation, immune suppression, or advanced malignoma. A 61-year-old man was admitted with severe back pain 1 day after uncomplicated colonoscopic polypectomy. With the exception of preexisting minor depression, the patient had been previously in excellent health. The computed tomography scan showed retroperitoneal emphysema in the left psoas muscle. During exploratory laparotomy, a spreading retroperitoneal phlegmon with pneumoretroperitoneum and a secondary peritonitis were found. A macroscopic perforation of the gut, particularly at the polypectomy sites was excluded. After the operation, the patient evolved in a septic shock condition and had pulmonary failure. Before hyperbaric oxygen therapy could be employed, the patient died. The autopsy showed a massive gas gangrene of the retroperitoneum caused by Clostridium perfringens, but no macroscopic bowel perforation was detected. This is the first report of a case of gas gangrene after uncomplicated polypectomy without macroscopic perforation in an otherwise healthy individual. A microperforation due to mucosal defect after polypectomy was most likely the entry point for the bacteria. We conclude that clostridial myonecrosis should be considered in unclear abdominal infections, even if the patient's history is not typical as in the present case.

Hereditary spastic paraplegia: LOD-score considerations for confirmation of linkage in a heterogeneous trait.

Hereditary spastic paraplegia (HSP) is a degenerative disorder of the motor system, defined by progressive weakness and spasticity of the lower limbs. HSP may be inherited as an autosomal dominant (AD), autosomal recessive, or an X-linked trait. AD HSP is genetically heterogeneous, and three loci have been identified so far: SPG3 maps to chromosome 14q, SPG4 to 2p, and SPG4a to 15q. We have undertaken linkage analysis with 21 uncomplicated AD families to the three AD HSP loci. We report significant linkage for three of our families to the SPG4 locus and exclude several families by multipoint linkage. We used linkage information from several different research teams to evaluate the statistical probability of linkage to the SPG4 locus for uncomplicated AD HSP families and established the critical LOD-score value necessary for confirmation of linkage to the SPG4 locus from Bayesian statistics. In addition, we calculated the empirical P-values for the LOD scores obtained with all families with computer simulation methods. Power to detect significant linkage, as well as type I error probabilities, were evaluated. This combined analytical approach permitted conclusive linkage analyses on small to medium-size families, under the restrictions of genetic heterogeneity.

Antibiotics are frequently administered in acute cholecystitis for preoperative prophylaxis or postoperative treatment. The optimal timing, choice, and duration of antibiotics are unclear. We conducted a retrospective review of all cases of acute cholecystitis between 1996 and 2001 at the American University of Beirut Medical Centre. A survey among general surgeons was also performed to describe the pattern of antibiotic prescribing in uncomplicated acute cholecystitis. A MEDLINE search for guidelines for antibiotic use in acute cholecystitis was conducted. The number of cases of acute cholecystitis was 79. The mean duration of postoperative antibiotic therapy was 5 days. There was no correlation between the severity of symptoms, gallbladder description, or positive gallbladder culture and the use of antibiotics postoperatively. Sixty five percent of interviewed surgeons would continue antibiotic therapy postoperatively for 3 or more days. Search of the medical literature failed to provide clear guidelines for antibiotic use in acute cholecystitis. The use of antibiotics in patients with acute cholecystitis is erratic and costly. Prospective studies are needed to better study the effectiveness of a short course of antibiotics in uncomplicated cases. The role of gallbladder culture in guiding antibiotic therapy should be defined as routine cultures add to the cost without evident benefit.

The occurrenceof postconcussive symptoms (PCS) following mild traumatic brain injury (TBI) in children may depend on cognitive reserve capacity. This prospective, longitudinal study examined whether the relationship between mild TBI and PCS is moderated by cognitive ability, which served as a proxy for cognitive reserve. Participants included 182 children with mild TBI and 99 children with orthopedic injuries (OI), ranging from 8 to 15 years of age when injured. Mild TBI were classified as complicated (n = 32) or uncomplicated (n = 150) depending on whether they were associated with trauma-related intracranial abnormalities on magnetic resonance imaging. PCS were assessed initially within 3 weeks of injury, and again at 1, 3, and 12 months post injury. The initial assessment also included standardized tests of children’s cognitive skills and retrospective parent ratings of pre-injury symptoms. Hierarchical linear modeling indicated that ratings of PCS were moderated jointly by cognitive ability and injury severity. Children of lower cognitive ability with a complicated mild TBI were especially prone to cognitive symptoms across time according to parents and to high acute levels of PCS according to children’s self-ratings. Cognitive reserve is an important moderator of the outcomes of mild TBI in children and adolescents. PMID:19835663

Symptomatic uncomplicated diverticular disease (SUDD) is a common gastrointestinal disease, because it affects about one fourth of the patient harboring colonic diverticula. To assess the effectiveness of mesalazine in improving symptoms (namely abdominal pain) and in preventing diverticulitis occurrence in patients with SUDD. Only randomized clinical trials (irrespective of language, blinding, or publication status) that compared mesalazine with placebo or any other therapy in SUDD were evaluated. The selected endpoints were symptom relief and diverticulitis occurrence at maximal follow-up. Absolute risk reduction (ARR, with 95% confidence interval) and the number needed to treat were used as measures of the therapeutic effect. Six randomized clinical trials enrolled 1021 patients: 526 patients were treated with mesalazine and 495 with placebo or other therapies. Symptom relief with mesalazine was always larger than that with placebo and other therapies. However, absolute risk reduction was significant only when mesalazine was compared with placebo, a high-fiber diet, and low-dose rifaximin. The incidence of diverticulitis with mesalazine was lower than that observed with placebo and other treatments, being significant only when compared with placebo. Mesalazine is effective in achieving symptom relief and primary prevention of diverticulitis in patients with SUDD.

Management of Diverticular Disease in Scandinavia.

Throughout the last century, the incidence of diverticular disease of the colon has increased tremendously in industrialized countries; nevertheless, the management of this condition is still controversial. Although several international guidelines for the management of diverticular disease are based on the same evidence, the recommendations differ greatly, emphasizing the lack of high-quality prospective studies. In Scandinavia, official guidelines for the management of diverticular disease exist only in Denmark. However, the treatment policies are quite similar in all Scandinavian countries. Computed tomography is the first choice for imaging of acute diverticulitis and its complications. Furthermore, the use of antibiotics in uncomplicated diverticulitis is nearly abandoned in Scandinavia, whereas several international guidelines still recommend their use. There is a broad consensus that abscesses secondary to acute diverticulitis can safely be managed with percutaneous drainage, which is in line with international recommendations. The surgical management of perforated diverticulitis with peritonitis is still as controversial in Scandinavia as elsewhere. Common surgical options are laparoscopic peritoneal lavage, primary resection with anastomosis, and primary resection with terminal colostomy (Hartmann's procedure). Elective sigmoid resection in patients with diverticular disease seems to be performed less frequently in Scandinavia than in other European countries; the right indications are a current matter of debate. Symptomatic uncomplicated diverticular disease in the absence of diverticulitis has not gained great attention in Scandinavia.

To assess emotion recognition from dynamic facial, vocal and musical expressions in sub-groups of adults with traumatic brain injuries (TBI) of different severities and identify possible common underlying mechanisms across domains. Forty-one adults participated in this study: 10 with moderate-severe TBI, nine with complicated mild TBI, 11 with uncomplicated mild TBI and 11 healthy controls, who were administered experimental (emotional recognition, valence-arousal) and control tasks (emotional and structural discrimination) for each domain. Recognition of fearful faces was significantly impaired in moderate-severe and in complicated mild TBI sub-groups, as compared to those with uncomplicated mild TBI and controls. Effect sizes were medium-large. Participants with lower GCS scores performed more poorly when recognizing fearful dynamic facial expressions. Emotion recognition from auditory domains was preserved following TBI, irrespective of severity. All groups performed equally on control tasks, indicating no perceptual disorders. Although emotional recognition from vocal and musical expressions was preserved, no correlation was found across auditory domains. This preliminary study may contribute to improving comprehension of emotional recognition following TBI. Future studies of larger samples could usefully include measures of functional impacts of recognition deficits for fearful facial expressions. These could help refine interventions for emotional recognition following a brain injury.

Maintenance therapy: is there still a place for antireflux surgery?

Effective and safe maintenance medical therapy for uncomplicated reflux esophagitis is now feasible with omeprazole and it is likely that other H+K+ATPase blockers, and possibly very high dose H2 receptor antagonist regimens, will also be acceptable. In addition, many patients with ulceration, strictures, and Barrett's esophagus will respond to conservative medical therapy and a proportion of patients with erosive esophagitis may remain in remission with cisapride or with low dose H2 receptor antagonists, if disease is less severe. Thus, there is now a medical "gold standard" against which surgical therapy for uncomplicated esophagitis must be judged and it is essential that all future studies be conducted with clearly defined criteria for the assessment of the symptoms and endoscopic signs of esophagitis and its complications. As ever, the patient's wishes are paramount, but he or she must be allowed to select his or her therapy on the basis of a balanced and fully informed assessment of the long-term and short-term risks of all therapeutic modalities. The burdensome prospect of lifelong tablet ingestion and its potential dangers must be weighed against the alternative, in up to 30% of cases, that surgery may produce dysphagia, gas bloat, or dumping with no guarantee of a long-term cure.

Urinary tract infections (UTIs) are relatively common in women and may be classified as uncomplicated or complicated, depending upon the urinary tract anatomy and physiology. Acute uncomplicated cystitis (AUC) occurs when urinary pathogens from the bowel or vagina colonize the periurethral mucosa and reach the bladder. The vast majority of episodes in healthy women involving the same bacterial strain that caused the initial infection are thought to be reinfections. About 90% of AUC are caused by uropathogenic Escherichia coli (UPEC), but Proteus mirabilis also plays an important role. Several studies support the importance of cranberry (Vaccinium macrocarpon) proanthocyanidins in preventing adhesion of P-fimbriated UPEC to uroepithelial cells. In this study, we evaluated the in vitro anti-adhesion activity of A2-linked proanthocyanidins from cranberry on a UPEC and Proteus mirabilis strains and their possible influence on urease activity of the latter. A significant reduction of UPEC adhesion (up to 75%) on the HT1376 cell line was observed vs. control. For the strains of P. mirabilis there was also a reduction of adhesion (up to 75%) compared to controls, as well as a reduction in motility and urease activity. These results suggest that A2-type cranberry proanthocyanidins could aid in maintaining urinary tract health. PMID:27025740

Recurrent Fever in Children.

Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time.

The initiative of the Spanish Ministry of Health «Commitment to quality of scientific societies», aims to reduce unnecessary interventions of healthcare professionals. The Spanish Association of Surgeons has selected 22 experts from the different sections that have participated in the identification of 26 proposals «do not do» to be ordered by the expected impact its implementation would have according to the GRADE methodology. From these proposals, the Delphi technique was used to select 5 recommendations presented in more detail in this article. The 5 selected recommendations are: Do not perform cholecystectomy in patients with asymptomatic cholelithiasis; do not keep bladder catheterization more than 48hours; do not extend antibiotic prophylaxis treatments more than 24hours after a surgical procedure; do not perform routine antibiotic prophylaxis for uncomplicated clean and no prosthetic surgery; and do not use antibiotics postoperatively after uncomplicated appendicitis. The Spanish Association of Surgeons's participation in this campaign has allowed a reflection on those activities that do not add value in the field of surgery and it is expected that the spread of this process serves to reduce its performance.

All artemisinin-based combination therapies (ACTs), recommended by the World Health Organization, are 3-day regimens. A considerable level of non-compliance on ACTs has been reported from some countries. The study aimed to assess the therapeutic efficacy of single dose treatment with new generation ACT containing artemisinin plus naphthoquine. An oral single dose of eight tablets (400 mg of naphthoquine+1000 mg artemisinin) of the combination drug was administered to adult uncomplicated falciparum malaria patients. Observations of fever, parasite clearance and reappearance, and other clinical manifestations were made on Days 0, 1, 2, 3, 7, 14, 21 and 28. Fifty-three adult falciparum positive cases, with fever or history of fever within the previous 24 h, were included in the final evaluation of the study. Mean fever clearance time, parasite clearance time were 18.2+/-8.6 h and 34.6+/-14.3 h, respectively. Adequate clinical and parasitological response was achieved in 52 cases, the rate being 98.1% (95% CI, 91.1-99.9). One patient was classified as late parasitological failure because of the reappearance of falciparum parasite on Day 14. The drug was well tolerated and no adverse reactions were detected in the patients. Since it is a single dose therapy, health workers can administer the drug as directly observed treatment.

The clinical outcome of falciparum malaria in endemic areas is influenced by erythrocyte polymorphisms including the ABO blood groups. Studies have reported association of ABO blood group to resistance, susceptibility, and severity of P. falciparum malaria infection. Individuals with blood group "A" have been found to be highly susceptible to falciparum malaria whereas blood group "O" is said to confer protection against complicated cases. We analyzed samples from 293 young children less than six years old with malaria in the Korle-Bu Teaching Hospital in Accra, Ghana. It was observed that group O was present in about 16.1% of complicated cases weighed against 40.9% of uncomplicated controls. Individuals with complicated malaria were about twice likely to be of blood groups A and B compared to group O (A versus O, OR = 1.90, 95% CI = 1.59-2.26, P < 0.0001; B versus O, OR = 1.82. 95% CI = 1.57-2.23, P < 0.0001). Blood group O participants with complicated diseases had low parasitaemia compared to the other blood groups (P < 0.0001). This may give blood group O individuals a survival advantage over the other groups in complicated malaria as suggested. Participants with complicated falciparum malaria were generally anaemic and younger than those with uncomplicated disease.

Staphylococcus saprophyticus is a uropathogenic Staphylococcus frequently isolated from young female outpatients presenting with uncomplicated urinary tract infections. We sequenced the whole genome of S. saprophyticus type strain ATCC 15305, which harbors a circular chromosome of 2,516,575 bp with 2,446 ORFs and two plasmids. Comparative genomic analyses with the strains of two other species, Staphylococcus aureus and Staphylococcus epidermidis, as well as experimental data, revealed the following characteristics of the S. saprophyticus genome. S. saprophyticus does not possess any virulence factors found in S. aureus, such as coagulase, enterotoxins, exoenzymes, and extracellular matrix-binding proteins, although it does have a remarkable paralog expansion of transport systems related to highly variable ion contents in the urinary environment. A further unique feature is that only a single ORF is predictable as a cell wall-anchored protein, and it shows positive hemagglutination and adherence to human bladder cell associated with initial colonization in the urinary tract. It also shows significantly high urease activity in S. saprophyticus. The uropathogenicity of S. saprophyticus can be attributed to its genome that is needed for its survival in the human urinary tract by means of novel cell wall-anchored adhesin and redundant uro-adaptive transport systems, together with urease.

Laparoscopic resection for diverticular disease.

The role of laparoscopic surgery in treatment of patients with diverticulitis is unclear. A retrospective comparison of laparoscopic with conventional surgery for patients with chronic diverticulitis was performed to assess morbidity, recovery from surgery, and cost. Records of patients undergoing elective resection for uncomplicated diverticulitis from 1992 to 1994 at a single institution were reviewed. Laparoscopic resection involved complete intracorporeal dissection, bowel division, and anastomosis with extracorporeal placement of an anvil. Sigmoid and left colon resections were performed laparoscopically in 25 patients and by open technique in 17 patients by two independent operating teams. No significant differences existed in age, gender, weight, comorbidities, or operations performed. In the laparoscopic group, three operations were converted to open laparotomy (12 percent) because of unclear anatomy. Major complications occurred in two patients who underwent laparoscopic resection, both requiring laparotomy, and in one patient in the conventional surgery group who underwent computed tomographic-guided drainage of an abscess. Patients who underwent laparoscopic resection tolerated a regular diet sooner than patients who underwent conventional surgery (3.2 +/- 0.9 vs. 5.7 +/- 1.1 days; P < 0.001) and were discharged from the hospital earlier (4.2 +/- 1.1 vs. 6.8 +/- 1.1 days; P < 0.001). Overall costs were higher in the laparoscopic group than the open surgery group ($10,230 +/- 49.1 vs. $7,068 +/- 37.1; P < 0.001) because of a significantly longer total operating room time (397 +/- 9.1 vs. 115 +/- 5.1 min; P < 0.001). Follow-up studies with a mean of one year revealed two port site infections in the laparoscopic group and one wound infection in the open group. Of patients undergoing conventional resection, one patient experienced a postoperative bowel obstruction that was managed nonoperatively, and, in one patient, an incarcerated incisional hernia developed that required urgent laparotomy. Laparoscopic resection in patients with chronic diverticulitis is safe, with faster recovery and shorter hospital stay compared with conventional open surgery. Higher cost of operating room usage time makes the laparoscopic technique difficult to justify economically. Simplification of operating room use and better case selection may improve cost-effectiveness of the laparoscopic approach.

Chronic alcohol abuse results in morphological, metabolic, and functional brain damage which may, to some extent, be reversible with early effects upon abstinence. Although morphometric, spectroscopic, and neuropsychological indicators of cerebral regeneration have been described previously, the overall amount and spatial preference of early brain recovery attained by abstinence and its associations with other indicators of regeneration are not well established. We investigated global and local brain volume changes in a longitudinal two-timepoint study with T1-weighted MRI at admission and after short-term (6-7 weeks) sobriety follow-up in 15 uncomplicated, recently detoxified alcoholics. Volumetric brain gain was related to metabolic and neuropsychological recovery. On admission and after short-term abstinence, structural image evaluation using normalization of atrophy (SIENA), its voxelwise statistical extension to multiple subjects, proton MR spectroscopy (1H-MRS), and neuropsychological tests were applied. Upon short-term sobriety, 1H-MRS levels of cerebellar choline and frontomesial N-acetylaspartate (NAA) were significantly augmented. Automatically detected global brain volume gain amounted to nearly two per cent on average and was spatially significant around the superior vermis, perimesencephalic, periventricular and frontal brain edges. It correlated positively with the percentages of cerebellar and frontomesial choline increase, as detected by 1H-MRS. Moreover, frontomesial NAA gains were associated with improved performance on the d2-test of attention. In 10 age- and gender-matched healthy control subjects, no significant brain volume or metabolite changes were observed. Although cerebral osmotic regulations may occur initially upon sobriety, significant increases of cerebellar choline and frontomesial NAA levels detected at stable brain water integrals and creatine concentrations, serum electrolytes and red blood cell indices in our patient sample suggest that early brain recovery through abstinence does not simply reflect rehydration. Instead, even the adult human brain and particularly its white matter seems to possess genuine capabilities for regrowth. Our findings emphasize metabolic as well as regionally distinct morphological capacities for partial brain recovery from toxic insults of chronic alcoholism and substantiate early measurable benefits of therapeutic sobriety. Further understanding of the precise mechanisms of this recovery may become a valuable model of brain regeneration with relevance for other disorders.

Artemisinin combination therapy for the treatment of uncomplicated malaria includes artemether plus lumefantrine, artesunate plus amodiaquine, artesunate plus mefloquine, artesunate plus sulfadoxine-pyrimethamine and dihydroartemisinin plus piperaquine. These drugs are safe and efficacious at present. The emergence of artemisinin resistant parasites in SE Asia means that there is a need to optimise drug dosing and investigate novel therapies to maintain the impressive reduction in malaria mortality which has been seen in the past decade.

Quantitation of anticonvulsant drugs in serum by gas-chromatography on the stationary phase SP-2510.

A new column packing, SP-2510 DA (Supelco, Inc., Bellefonte, Pa. 16823), is an excellent stationary phase for the determination of a wide variety of anticonvulsant drugs by gas--liquid chromatography without derivatization. However, when uncomplicated extraction procedures are used, serum cholesterol interferes with the determination of primidone. By the simple expedient of adding a short "pre-column" containing another phase (SP-2250 DA) the problem is overcome.

Alcohol Use Disorders present a significant public health problem in France and the United States (U.S.), but whether the untoward effect of alcohol on the brain results in similar damage in both countries remains unknown. Accordingly, we conducted a retrospective collaborative investigation between two French sites (Caen and Orsay) and a U.S. laboratory (SRI/Stanford University) with T1-weighted, structural MRI data collected on a common imaging platform (1.5T, General Electric) on 288 normal controls (NC), 165 uncomplicated alcoholics (ALC), and 26 patients with alcoholic Korsakoff’s syndrome (KS) diagnosed at all sites with a common interview instrument. Data from the two countries were pooled, then preprocessed and analyzed together at the U.S. site using atlas-based parcellation. National differences indicated that thalamic volumes were smaller in ALC in France than the U.S. despite similar alcohol consumption levels in both countries. By contrast, volumes of the hippocampus, amygdala, and cerebellar vermis were smaller in KS in the U.S. than France. Estimated amount of alcohol consumed over a lifetime, duration of alcoholism, and length of sobriety were significant predictors of selective regional brain volumes in France and in the U.S. The common analysis of MRI data enabled identification of discrepancies in brain volume deficits in France and the U.S. that may reflect fundamental differences in the consequences of alcoholism on brain structure between the two countries, possibly related to genetic or environmental differences.

Cardiac diastolic function after recovery from pre-eclampsia.

PubMed

Soma-Pillay, P; Louw, M C; Adeyemo, A O; Makin, J; Pattinson, R C

Pre-eclampsia is associated with significant changes to the cardiovascular system during pregnancy. Eccentric and concentric remodelling of the left ventricle occurs, resulting in impaired contractility and diastolic dysfunction. It is unclear whether these structural and functional changes resolve completely after delivery. The objective of the study was to determine cardiac diastolic function at delivery and one year post-partum in women with severe pre-eclampsia, and to determine possible future cardiovascular risk. This was a descriptive study performed at Steve Biko Academic Hospital, a tertiary referral hospital in Pretoria, South Africa. Ninety-six women with severe preeclampsia and 45 normotensive women with uncomplicated pregnancies were recruited during the delivery admission. Seventy-four (77.1%) women in the pre-eclamptic group were classified as a maternal near miss. Transthoracic Doppler echocardiography was performed at delivery and one year post-partum. At one year post-partum, women with pre-eclampsia had a higher diastolic blood pressure (p = 0.001) and body mass index (p = 0.02) than women in the normotensive control group. Women with early onset pre-eclampsia requiring delivery prior to 34 weeks' gestation had an increased risk of diastolic dysfunction at one year post-partum (RR 3.41, 95% CI: 1.11-10.5, p = 0.04) and this was irrespective of whether the patient had chronic hypertension or not. Women who develop early-onset pre-eclampsia requiring delivery before 34 weeks are at a significant risk of developing cardiac diastolic dysfunction one year after delivery compared to normotensive women with a history of a low-risk pregnancy.
