A three-dimensional, time-dependent, direct numerical simulation of low-Reynolds number turbulent flow in a mildly curved channel was performed, and the results examined to determine the mechanism by which curvature affects wall-bounded turbulent shear flows. A spectral numerical method with about one-million modes was employed, and no explicit subgrid scale model was used. The effects of curvature on this flow were determined by comparing the concave and convex sides of the channel. The observed effects are consistent with experimental observations for mild curvature. The most significant difference in the turbulence statistics between the concave and convex sides is in the Reynolds shear stress. This is accompanied by significant differences in the terms of the Reynolds shear stress balance equations. In addition, it was found that stationary Taylor-Goertler vortices were present and that they had a significant effect on the flow by contributing to the mean Reynolds shear stress, and by enhancing the difference between the wall shear stresses.

Despite the importance of this issue, less has been paid to the influence of exercise on the neural side effects of anabolic androgenic steroids and mechanisms. We investigated the effects of two levels of endurance exercise on neurodegeneration side effects of nandrolone. The study period was 8 weeks. Wistar rats were divided into nine groups including the control (CTL) group, mild exercise (mEx) group, and vehicle (Arach) group which received arachis oil intramuscularly, nandrolone (Nan) group which received nandrolone decanoate 5 mg/kg two times weekly, mEx+Arach group which treated with arachis oil along with mild exercise, mEx+Nan group which treated with nandrolone along with mild exercise, severe exercise (sEx) group, sEx+Arach, and sEx+Nan groups. Finally, brain samples were taken for histopathological, biochemical, and western blot analysis. Nandrolone significantly decreased the intact cells of the hippocampus, total antioxidant capacity (TAC) (P < 0.05 versus CTL and Arach groups), TAC to malondialdehyde ratio (TAC/MDA), and Bcl-2. Nandrolone increased the Bax/Bcl-2 ratio of the brain tissue (P < 0.01 versus CTL and Arach groups). Combination of mild exercise and nandrolone rescued the intact cells to some extent, and this effect was associated with the improvement of Bcl-2 level and Bax/Bcl-2 ratio of brain tissue. Combination of severe exercise and nandrolone rescued the intact cells and improved the TAC, TAC/MDA, and Bax/Bcl-2 ratios. The findings suggest that low- and high-intensity endurance exercise decreased the risk of neurodegeneration effect of nandrolone in the hippocampus of rats. This effect can be explained by the regulation of the redox system and cell homeostasis.

The importance of adolescent engagement in health decisions and public health programs such as immunisation is becoming increasingly recognised. Understanding adolescent preferences and further identifying barriers and facilitators for immunisation acceptance is critical to the success of adolescent immunisation programs. This study applied a discrete choice experiment (DCE) to assess vaccination preferences in adolescents. This study was conducted as a cross-sectional, national online survey in Australian adolescents. The DCE survey evaluated adolescent vaccination preferences. Six attributes were assessed including disease severity, target for protection, price, location of vaccination provision, potential side effects and vaccine delivery method. A mixed logit model was used to analyse DCE data. This survey was conducted between December 2014 and January 2015. Of 800 adolescents aged 15 to 19 years, stronger preferences were observed overall for: vaccination in the case of a life threatening illness (p<0.001), lower price vaccinations (p<0.001), mild but common side effects (p = 0.004), delivery via a skin patch (p<0.001) and being administered by a family practitioner (p<0.001). Participants suggested that they and their families would be willing to pay AU$394.28 (95%CI: AU$348.40 to AU$446.92) more for a vaccine targeting a life threatening illness than a mild-moderate illness, AU$37.94 (95%CI: AU$19.22 to AU$57.39) more for being vaccinated at a family practitioner clinic than a council immunisation clinic, AU$23.01 (95%CI: AU$7.12 to AU$39.24) more for common but mild and resolving side effects compared to rare but serious side effects, and AU$51.80 (95%CI: AU$30.42 to AU$73.70) more for delivery via a skin patch than injection. Consideration of adolescent preferences may result in improved acceptance of, engagement in and uptake of immunisation programs targeted for this age group.

To explore and quantify men's preferences and willingness to pay (WTP) for attributes of medications for lower urinary tract symptoms associated with benign prostatic hyperplasia using a discrete choice experiment. Men in the UK aged ≥45 years with moderate-to-severe lower urinary tract symptoms/benign prostatic hyperplasia (based on self-reported International Prostate Symptom Score ≥8) were recruited. An online discrete choice experiment survey was administered. Eligible men were asked to consider different medication scenarios and select their preferred medication according to seven attributes: daytime and nighttime (nocturia) urinary frequency, urinary urgency, sexual and nonsexual side effects, number of tablets/day, and cost/month. A mixed-logit model was used to estimate preferences and WTP for medication attributes. In all, 247 men completed the survey. Men were willing to trade-off symptom improvements and treatment side effects. Men preferred medications that reduced urinary urgency and reduced day- and nighttime urinary frequency. Men preferred medications without side effects (base-case level), but did not care about the number of tablets per day. WTP for symptomatic improvement was £25.33/month for reduced urgency (urge incontinence to mild urgency), and £6.65/month and £1.39/month for each unit reduction in night- and daytime urination frequency, respectively. The sexual and nonsexual side effects reduced WTP by up to £30.07/month. There was significant heterogeneity in preferences for most attributes, except for reduced urinary urgency from urge incontinence to mild urgency and no fluid during ejaculation (dry orgasm). To compensate for side effects, a medicine for lower urinary tract symptoms/benign prostatic hyperplasia must provide a combination of benefits, such as reduced urgency of urination plus reduced nighttime and/or reduced daytime urination.

Though typically mild, side effects to the influenza virus vaccine are common and may contribute to negative perceptions including the belief that the vaccine can cause the flu. However, the extent to which subjective symptoms correspond with biological response indicators is poorly understood. This study examined associations among subjective side effects (soreness at the site of injection and illness-like symptoms), serum proinflammatory cytokines and body temperature a baseline, 1, 2, and 3 days following receipt of trivalent inactivated influenza vaccine (IIV3) in a sample of 56 women 18-40 years in age. In relation to local reactions, women reporting being very sore at the injection site at 1 day post-vaccination exhibited greater increases in serum TNF-α and MIF in the days following vaccination compared to those with no or mild soreness. In addition, higher basal body temperature was observed in this group compared to other groups (98.7°F versus 98.0-98.1°). In relation to systemic reactions, women endorsing illness-like symptoms (headache, fatigue, nausea, sore throat, dizziness, achiness, or mild fever) exhibited marginally higher IL-6 at baseline (p=0.055) and greater increases in serum MIF at 2 days post-vaccination than those reporting no systemic symptoms. Associations of systemic symptoms with inflammatory responses were not accounted for by concomitant local reactions. As expected, antibody responses to the vaccine were highly similar in women regardless of local or systemic symptoms. These results are consistent with the notion that subjective reports of local and systemic reactions following vaccination may be predicted by and correspond with biological indicators of inflammatory status, but are not meaningful predictors of antibody responses. To improve adherence to vaccine recommendations, clinicians should provide assurance that such symptoms may be related to normal mild inflammatory responses to the vaccine and do not reflect immunogenicity.

The inconsistency in clinician and patient ratings of clozapine-induced side effects underscore the need to supplement clinician-based estimates of side effects with patient-reported ones. The main aims of the study are validation of the Glasgow antipsychotic side-effects scale for clozapine (GASS-C) in Serbian inpatients/outpatients with schizophrenia or schizo-affective disorder and recommendations for its future use, based on common and rare clozapine-associated side-effects. The GASS-C was administered to 95 outpatients/inpatients diagnosed with schizophrenia, schizoaffective, or chronic psychotic disorder. The scale showed good overall reliability, with an internal consistency coefficient of α = 0.84, an average retest coefficient of rho = 0.76, and a Spearman-Brown coefficient of validity of 0.81. Side effects were absent or mild in 64.2% of the patients, moderate in 31.6%, severe in 4.2%; 14% of the subjects considered their symptoms distressing. The most commonly reported side-effects were drowsiness, thirst, frequent urination, and dry mouth. Women reported more side effects than men, and patients not in a relationship reported significantly fewer side effects than patients in a relationship. Results indicate a weak positive correlation (rho = 0.231; p = .025) between severity of side effects and clozapine dose. The GASS-C showed good psychometric characteristics in clinical population of patients on clozapine. In future studies, clozapine serum concentrations should be measured when using the GASS-C to monitor side effects.

We conducted a clinical study that tested the effect of suppressive treatment with the botanical product Gene-Eden-VIR/Novirin on genital herpes. Our previous paper showed that the treatment decreased the number of genital herpes outbreaks without any side effects. It also showed that the clinical effects of Gene-Eden-VIR/Novirin are mostly better than those reported in the studies that tested acyclovir, valacyclovir, and famciclovir. The current paper reports the effect of suppressive treatment with Gene-Eden-VIR/Novirin on the duration of outbreaks, in severe and mild genital herpes cases. The framework was a retrospective chart review. The population included 137 participants. The treatment was 1-4 capsules per day. The duration of treatment was 2-48 months. The study included three controls: baseline, no-treatment, and dose-response. The treatment decreased the duration of outbreaks in 87 % of participants and decreased the mean duration of outbreaks from 8.77 days and 6.7 days in the control groups to 2.87 days in the treatment group (P < 0.001, both groups). All participants reported no adverse experiences. This paper shows that suppressive treatment with Gene-Eden-VIR/Novirin decreased the duration of genital herpes outbreaks, in both severe and mild cases, without any side effects. Based on the results reported in this and our previous paper, we recommend suppressive treatment with Gene-Eden-VIR/Novirin as a natural alternative to both suppressive and episodic treatments with current drugs, in both severe and mild genital herpes cases.

2015-10-01

Treatment of anxiety and depression, the most common psychiatric symptoms in older adults with mild dementia, requires innovative approaches due to the high cost and significant side effects associated with traditional pharmacological interventions. Alternative non-pharmacological therapies, such as music, when used in conjunction with pharmacological treatment, have the potential to alleviate symptoms of anxiety and depression in older adults diagnosed with mild dementia. The purpose of this review was to examine the evidence of music's efficacy in improving symptoms of anxiety and depression in older adults with mild dementia. Four databases (Medline, CINAHL, PsychInfo, PubMed) were searched using the terms "music," "music therapy," "music intervention," "singing," "dementia," "anxiety," and/or "depression," identifying ten studies that met the inclusion and exclusion criteria. The poor methodological rigor of the studies precluded reaching consensus on the efficacy of a music intervention in alleviating symptoms of anxiety and depression in older adults with mild dementia. There was inconclusive evidence as to whether music interventions are effective in alleviating symptoms of anxiety and depression in older adults with mild dementia due to the poor methodological rigor. However, with improved designs guided by a deeper understanding of how music engages the aging brain, music may emerge as an important adjunct therapy to improving the lives of older adults with mild dementia.

While device-based acne treatments are widely applied for patients not tolerating conventional medications, related controlled studies have been still limited. Recently, non-ablative 1450-nm diode laser (DL) and fractional microneedling radiofrequency (FMR) have been effectively used for acne, in addition to well-recognized dermal remodelling effects. To compare the clinical course of acne treatment between DL and FMR. Twenty-five Korean patients with mild-to-moderate facial acne completed treatments with DL and FMR through a 20-week, randomized split-face study. One randomly assigned half side of each patient's face received DL and the other side by FMR. Treatments were scheduled to receive three consecutive sessions at 4-week intervals. Objective assessments including revised Leeds grades, lesion counts, sebum output measurements, and patients' subjective satisfaction were investigated. Both DL and FMR demonstrated steady improvement of acne and seborrhoea during treatment sessions. While results between two devices were similar during treatment sessions, FMR was superior to DL in the 12-week follow-up. Patients' subjective assessments for seborrhoea improvement were similar between two devices, while those for acne, skin texture, and acne scars were more satisfactory for FMR. For safety profile, no significant difference was observed between two regimens, while mild postinflammatory hyperpigmentation was observed only in DL side. Both DL and FMR demonstrated efficacies for acne and seborrhoea, with reasonable safety profile. FMR was more effective than DL for the long-term maintenance, and subjective assessments for texture and scar improvements. Therefore, a few sessions of these devices would be a viable option for acne treatments. © 2017 European Academy of Dermatology and Venereology.

To systematically investigate the literature for the influence of sublingual nitroglycerin administration on coronary diameter, the number of evaluable segments, image quality, heart rate and blood pressure, and diagnostic accuracy of coronary computed tomography (CT) angiography. A systematic search was performed in PubMed, EMBASE and Web of Science. The studies were evaluated for the effect of sublingual nitroglycerin on coronary artery diameter, evaluable segments, objective and subjective image quality, systemic physiological effects and diagnostic accuracy. Due to the heterogeneous reporting of outcome measures, a narrative synthesis was applied. Of the 217 studies identified, nine met the inclusion criteria: seven reported on the effect of nitroglycerin on coronary artery diameter, six on evaluable segments, four on image quality, five on systemic physiological effects and two on diagnostic accuracy. Sublingual nitroglycerin administration resulted in an improved evaluation of more coronary segments, in particular, in smaller coronary branches, better image quality and improved diagnostic accuracy. Side effects were mild and were alleviated without medical intervention. Sublingual nitroglycerin improves the coronary diameter, the number of assessable segments, image quality and diagnostic accuracy of coronary CT angiography without major side effects or systemic physiological changes. • Sublingual nitroglycerin administration results in significant coronary artery dilatation. • Nitroglycerin increases the number of evaluable coronary branches. • Image quality is improved the most in smaller coronary branches. • Nitroglycerin increases the diagnostic accuracy of coronary CT angiography. • Most side effects are mild and do not require medical intervention.

Rotigotine is the first transdermal non-ergolinic dopaminergic agonist used in the treatment of Parkinson's disease. It has several important advantages such as once-daily administration, absence of interactions with food, steady levels in plasma and continuous dopaminergic stimulation. Although its systemic side effects are similar to those seen in other dopaminergic agonists, rotigotine also has local side effects derived from the site of application. The aim of this paper is to review those local problems. A retrospective analysis was carried out in order to identify the first 165 patients treated with rotigotine. Patients with intracranial lesions, psychiatric pathology or dementia were excluded. Patients were evaluated before and at two, four and six months after beginning treatment with rotigotine. In all, 94 males and 71 females were identified, with an average age of 65.2 and an average rotigotine daily dose of 11.3 mg. Local side effects were present in 21 patients and they were usually mild. Two patients abandoned the treatment because of these local adverse events, presenting erythema and prurigo. Thirty patients complained about lack of adherence of the patch, specially when it was hot, and 36 about the formation of wrinkles in the patch. None of these problems was associated to motor fluctuations or other complications. Local complications of transdermal rotigotine are mild but frequent. We consider it is necessarily to take them into account to get a better treatment of patients suffering from Parkinson's disease.

Purpose: To retrospectively review the results of radiotherapy for Peyronie's disease. Patients and Methods: In the time interval 1983-2000, 154 patients in our clinic were irradiated for Peyronie's disease. Of those, 101 had at least one complete follow-up data set and are the subject of this study. In the majority of patients, penis deviation was between 30 and 50{sup o}, there were one or two indurated foci with a diameter between 5 and 15 mm. Pain was recorded in 48/92 patients. Seventy-two of the 101 patients received radiotherapy with a total dose of 30 Gy, and 25 received 36 Gymore » in daily fractions of 2.0 Gy. The remaining patients received the following dosage: 34 Gy (1 patient), 38-40 Gy (3 patients). Mean duration of follow-up was 5 years. Results: The best results ever at any time during follow-up were an improvement of deviation in 47%, reduction of number of foci in 32%, reduction of size of foci in 49%, and less induration in 52%. Approximately 50% reported pain relief after radiotherapy. There were 28 patients with mild acute dermatitis and only 4 patients with mild urethritis. There were no long-term side effects. Conclusion: Our results compare well with those of other studies in the literature. In our patient cohort, radiotherapy was an effective therapy option with only very rare and mild side effects.« less

Investigation of gaseous ozone for MRSA decontamination of hospital side-rooms.

Berrington, A W; Pedler, S J

1998-09-01

A domestic, gaseous ozone generator was investigated for use in the decontamination of hospital side-rooms that have housed patients colonized with methicillin-resistant Staphylococcus aureus (MRSA). Three models of bacterial contamination were used. These were exposed to ozone generation in a standard hospital side-room for 4 and 7 h. A methicillin-sensitive and a methicillin-resistant strain of S. aureus were compared. Ozone concentrations of 0.14 ppm were reached, levels which are sufficient to cause mild pulmonary toxicity. Bacterial counts were reduced in the vicinity of the gas generator in most instances, but the effect elsewhere in the room was, at best, limited. MRSA appeared more resistant to the effects of ozone than methicillin-sensitive S. aureus. We conclude that the device tested would be inadequate for the decontamination of such hospital side-rooms.

Direct numerical simulation of curved turbulent channel flow

NASA Technical Reports Server (NTRS)

Moser, R. D.; Moin, P.

1984-01-01

Low Reynolds number, mildly curved, turbulent channel flow has been simulated numerically without subgrid scale models. A new spectral numerical method developed for this problem was used, and the computations were performed with 2 million degrees of freedom. A variety of statistical and structural information has been extracted from the computed flow fields. These include mean velocity, turbulence stresses, velocity skewness, and flatness factors, space time correlations and spectra, all the terms in the Reynolds stress balance equations, and contour and vector plots of instantaneous velocity fields. The effects of curvature on this flow were determined by comparing the concave and convex sides of the channel. The observed effects are consistent with experimental observations for mild curvature. The most significant difference in the turbulence statistics between the concave and convex sides was in the Reynolds shear stress. This was accompanied by significant differences in the terms of the Reynolds shear stress balance equations. In addition, it was found that stationary Taylor-Gortler vortices were present and that they had a significant effect on the flow by contributing to the mean Reynolds shear stress, and by affecting the underlying turbulence.

Oxidation of Peptides by Methyl(trifluoromethyl)dioxirane: the Protecting Group Matters

Representative Boc protected and acetyl protected peptide methyl esters bearing alkyl side chains undergo effective oxidation using methyl(trifluoromethyl)dioxirane (1b) under mild conditions. We observe a protecting group dependency in the chemoselectivity displayed by the dioxirane 1b. N-hydroxylation occurs in the case of the Boc protected peptides, side chain hydroxylation takes place in the case of acetyl protected peptides. Both are attractive transformations since they yield derivatized peptides that serve as valuable synthons. PMID:17221970

Boron compounds are being investigated as therapies for dermatologic conditions. Several features of boron chemistry make this element an ideal component in dermatologic treatments. We review the published dermatologically-relevant clinical trials and case studies pertaining to boron compounds. PubMed was utilized to query terms boron, chemistry, drug, development, dermatology, atopic dermatitis, psoriasis, onychomycosis, tavaborole, AN 2690, crisaborole, and AN 2728. Clinical trials, case studies, animal studies and in vitro studies. pertaining to atopic dermatitis, psoriasis and onychomycosis were included. Crisaborole 2% topical solution reduced atopic dermatitis lesions by approximately 60% when compared to pre-treatment baseline. Crisaborole maintains its dose-dependent effect in treatment of psoriasis and significantly reduces psoriatic plaques when compared to controls. Adverse effects were mild, frequency of events varied between studies. Crisaborole was well tolerated when applied to sensitive skin. Topical tavaborole significantly reduced or eliminated onychomycosis with minimal side effects compared to placebo. Tavaborole was effective in treating recalcitrant onychomycosis. Boron-based compounds form stable interactions with enzyme targets and are safe medications for the treatment of atopic dermatitis, psoriasis, and onychomycosis. The mild and rare side effects of topical boron-based compounds may make them ideal treatments for individuals with sensitive skin and pediatric populations.

Milder is better? advantages and disadvantages of "mild" ovarian stimulation for human in vitro fertilization

PubMed Central

2011-01-01

In the last decades, several steps have been made aiming at rendering human IVF more successful on one side, more tolerable on the other side. The "mild" ovarian stimulation approach, in which a lower-than-average dose of exogenous gonadotropins is given and gonadotropin treatment is started from day 2 to 7 of the cycle, represents a significant step toward a more patient's friendly IVF. However, a clear view of its virtues and defects is still lacking, because only a few prospective randomized trials comparing "mild" vs. conventional stimulation exist, and they do not consider some important aspects, such as, e.g., thawing cycles. This review gives a complete panorama of the "mild" stimulation philosophy, showing its advantages vs. conventional ovarian stimulation, but also discussing its disadvantages. Both patients with a normal ovarian responsiveness to exogenous gonadotropins and women with a poor ovarian reserve are considered. Overall, we conclude that the level of evidence supporting the use of "mild" stimulation protocols is still rather poor, and further, properly powered prospective studies about "mild" treatment regimens are required.

A systematic review of the psychiatric side-effects of efavirenz.

PubMed

Kenedi, Christopher A; Goforth, Harold W

2011-11-01

Concerns regarding the use of efavirenz in patients with a history of mental illness may predispose clinicians to not offer this agent to psychiatrically ill populations in spite of the convenience of once daily dosing, which can result in improved adherence in these at-risk populations. This systematic review examines the current data regarding the neuropsychiatric effects of efavirenz, and also attempts to provide guidance to clinicians using efavirenz to treat patients with mental illness. The review identified high rates of neuropsychiatric side effects including vivid dreams, insomnia and mood changes in approximately 50% of patients who initiate efavirenz. The effects begin quickly, commonly peak in the first 2 weeks, and are generally mild and transient in nature. Isolated case reports and uncontrolled data suggest higher rates of severe side effects; however, there is no clear evidence of a broadly increased risk of suicide or dangerous behavior for patients taking efavirenz as part of their antiretroviral regimen.

Methylphenidate Abuse and Psychiatric Side Effects

PubMed Central

Morton, W. Alexander; Stockton, Gwendolyn G.

2000-01-01

Methylphenidate is a central nervous system stimulant drug that has become the primary drug of choice in treating attention-deficit/hyperactivity disorder in children. Side effects are usually mild and are generally well tolerated by patients. Along with increases in prescribing frequency, the potential for abuse has increased. Intranasal abuse produces effects rapidly that are similar to the effects of cocaine in both onset and type. The clinical picture of stimulant abuse produces a wide array of psychiatric symptoms. There is little in the literature to differentiate methylphenidate from other stimulants when they are abused. The need for education of all involved with the use of methylphenidate is discussed to help prevent an increasing pattern of methylphenidate abuse. PMID:15014637

2004-10-01

Topical measures are still the mainstay in the therapy of mild-to-moderate acne vulgaris. Azelaic acid 20% in a cream formulation has been established as an efficacious and safe topical drug for 15 years. A new non-alcoholic hydrogel formulation containing 15% azelaic acid was clinically tested against two standard drugs--5% benzoyl peroxide (BPO) and 1% clindamycin. In two independent, randomized, blinded comparative trials 15% azelaic acid gel was clinically tested against 5% benzoyl peroxide (BPO) gel in 351 patients and against 1% clindamycin gel in 229 patients. The drugs were applied b.i.d. for 4 months. Azelaic acid 15% gel proved to be as effective as BPO and clindamycin with median % reduction of the inflamed lesion (papules and pustules) of 70%, and 71% respectively. The azelaic acid gel was well-tolerated, the side effects (local burning and irritation) were distinctly less than with BPO but more pronounced than with clindamycin. Despite these side effects, the treatment was well-accepted by the majority of patients. Azelaic acid gel is an effective topical monotherapy for mild-to-moderate acne vulgaris; its new gel form is an enrichment of acne therapy.

After more than two decades with interferon alfa-2a and 2b (IFN) as the only approved drugs in the adjuvant setting for melanoma, new treatment approaches like immune checkpoint inhibitors and BRAF-MEK inhibitors improve the progression free survival (PFS) and also the overall survival (OS). We compared physicians' preferences ("utilities") for health states associated with IFN therapy to their patients' preferences. Utilities describe a preference for a specific health state on a scale of 0 (as bad as death) to 1.0 (perfect health). We assessed utilities for health states associated with adjuvant IFN using the standard gamble technique in 108 physicians and 130 melanoma patients. Four IFN toxicity scenarios and three outcome scenarios were given to the participants. Both groups were asked for the 5-year disease free survival (DFS) they would need to accept the described IFN-related side effects. In both groups, utilities for melanoma relapse were significantly lower than for IFN side effects, showing that toxicity was more acceptable than relapse. Physicians indicated higher utilities for each scenario and needed lower 5-year DFS both in case of mild-to-moderate and severe side effects. Patients were willing to tolerate mild-to-moderate and severe toxicity for a 50% and 75% chance of 5-year DFS, while physicians only required a chance of 40% and 50%, respectively. Both physicians and patients rated melanoma recurrence much lower than even severe IFN side effects. In direct comparison, physicians rated cancer-related scenarios more positively and accepted IFN toxicity for an even lower treatment benefit.

Valproic acid (VPA) is a commonly used drug for epilepsy, psychiatric disorders and migraine and is frequently used in neurosurgical intensive care units. Though most of its side-effects are mild and transient, certain idiosyncratic side-effects have been attributed to VPA. Valproate induced hyperammonemia (VIH) is one such side-effect. VIH can produce symptoms of encephalopathy known as valproate induced hyperammonemic encephalopathy (VHE). VIH and VHE usually respond to withdrawal of VPA. However, in some cases VHE can be unresponsive to supportive measures and severe enough to be life-threatening. In such cases, dialysis can be used to rapidly reverse hyperammonemia and VHE and can prove to be a lifesaving measure. We report such a case of VIH and life-threatening VHE in a postoperative neurosurgical patient that was managed successfully with peritoneal dialysis.

To assess the psychiatric side effects of ketamine when administered in subanesthetic doses to hospitalized patients. It is hypothesized that such effects occur frequently. In this retrospective study, the medical records of 50 patients hospitalized on medical and surgical units at our facility who had continuous intravenous infusions of ketamine for pain or mild sedation were reviewed. Patient progress in the days following the start of ketamine infusion was reviewed and response to ketamine was noted. Twenty-two percent of the patients were noted to have some type of psychiatric reaction to ketamine, including agitation, confusion, and hallucinations. These reactions were relatively short lived, namely, occurring during or shortly after the infusions. No association was found between patient response to ketamine and gender, age, or infusion rate. Awareness of the psychiatric side effects of ketamine is an important consideration for clinicians administering this medication either for pain control or for depressive illness.

The clinical efficacy and the safety of chronic oral administration of cisapride, a new gastrointestinal prokinetic agent, (10 mg tid) and clebopride (0.5 mg tid) was assayed in 48 outpatients affected with functional dyspepsia, in a randomized double-blind study. Each of the drugs induced a significant reduction in dyspeptic symptoms after 2 and 4 weeks (p less than 0.001). Two patients, given clebopride, dropped out of the study because of severe side effects during the first week of treatment. Mild adverse reactions were reported in 6 out of 23 cisapride-treated patients and in 10 out of 20 clebopride-treated patients who completed the study. The most common side effect of cisapride was diarrhoea and that of clebopride was drowsiness. Cisapride appears to be as effective as clebopride in reducing dyspeptic symptoms and seems to induce less severe side effects.

Preterm birth is the major cause of neonatal mortality and morbidity worldwide and a huge cost burden on healthcare. Between 22 and 26 completed weeks of gestation, for every day that delivery is delayed, survival increases by 3%. Following a systematic review of the literature, we have provided an overview of the use of tocolytics for the prevention of preterm birth and have examined the fetal and maternal adverse effects of the various tocolytic agents currently in use. No tocolytic currently in use was developed specifically to treat preterm labour so most have multi-organ side effects. β2-agonists are relatively safe for the fetus but have rare and potentially serious maternal adverse effects. In contrast, prostaglandin synthetase inhibitors have potentially serious side effects for the fetus and neonate but have mild maternal gastrointestinal side effects. In Europe, the choice of first line therapy is either atosiban or nifedipine. The evidence base for atosiban is much more robust than for nifedipine. While their efficacy is similar, atosiban has placebo level side effects and is safer than nifedipine but is much more expensive.

No single effective topical treatment is available for treating all pathogenic factors causing acne vulgaris (AV). Salicylic acid (SA), tretinoin (all-TRA) and clindamycin phosphate (CDP) are known to to be effective agents depending on their comedolytic and anti-inflammatory properties. To compare the efficacy and tolerability of SA and CDP combination (SA+CDP) with all-TRA and CDP (all-TRA+CDP) in patients with mild to moderate facial AV. Forty-six patients aged between 18 and 35 years were enrolled in a 12-week prospective, single-blind, randomized and comparative clinical study. Efficacy was assessed by lesion counts, global improvement, quality of life index and measurement of skin barrier functions. Local side effects were also evaluated. Both combinations were effective in reducing total lesion (TL), inflammatory lesion (IL) and non-inflammatory lesion (NIL) counts and showed significant global improvement as evaluated by the investigator. At the end of the study, there was no significant difference between the two groups in terms of all lesion counts. In addition, TL counts decreased faster in the all-TRA+CDP group compared with those in the SA+CDP group, with a significant difference between the two groups occurring as early as 2 weeks. Safety evaluations demonstrated that the incidence of mild to moderate side effects generally peaked at week 2 and declined gradually thereafter. Both combinations did not have an effect on stratum corneum hydration, although skin sebum values decreased with SA+CDP treatment. Combination of SA+CDP and all-TRA+CDP was effective in decreasing lesion counts and well tolerated with minimal local cutaneous reactions in patients with mild to moderate AV. © 2010 The Authors.

Acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases. The peeling method has been recently found to be effective for acne treatment. This study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. In a prospective single-blinded clinical trial, 86 patients with acne were randomly assigned into two groups. In both groups, the routine treatment of acne (topical solution of erythromycin 4%, triclorocarban soap, and sunscreen) were used twice a day for 8 weeks. In addition, salicylic acid 30% for the control group and pyruvic acid 50% for the case group were used. In both groups, acne severity index (ASI) was calculated before and at week 2, 4, 6, and 8 of the treatment. Patient satisfaction was assessed at the end of the treatment. Side effects were recorded using a checklist. In both groups, the reduction in the number of comedones, papules, and ASI were statistically significant ( P < 0.001) in the course of treatment. However, it was not significant regarding the number of pustules ( P = 0.09). None of the number of comedone, papules, pustules, and ASI was statistically different between study groups. Both treatment groups had similar side effects except for scaling in the fifth session, which was significantly lower in salicylic acid - treated patients ( P = 0.015). Both pyruvic acid 50% and salicylic acid 30% are effective in the improvement of mild to moderate acne with no significant difference in efficacy and side effects.

In a group of older, arteriosclerotic hypertensive patients treated with an extract of Rauwolfia over a long period, a mild hypotensive effect was noted after weeks, or occasionally months, of therapy. No dramatic responses were seen, but the so-called “tranquilizing” effect was readily apparent and was appreciated by the patients. Side effects were usually relatively minor, were transient and rarely necessitated stopping the drug. PMID:13209377

The purpose of this prospective randomized single-blind clinical trial was to evaluate the effect of tilting the head on the anesthetic efficacy of inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis. Ninety-two patients were divided into two groups: the first group received IANB and the head was tilted in the direction of the block for 15 min, whereas the second group received IANB and the head was tilted to the opposite side. Access cavity preparation was initiated after 15 min. Success was defined as no pain or faint/weak/mild pain during endodontic access preparation and instrumentation. The anesthetic success rates were analyzed by Pearson chi-square test at 5% significance levels. The same side position and opposite side position yielded 41% and 30% anesthetic success rates, respectively; there was no significant difference between the two sides. Relative head position has no effect on the anesthetic success rate of IANB.

We report three cases of multicentric Castleman's disease (MCD) successfully treated with anti-interleukin-6 receptor antibody (tocilizumab). Tocilizumab was administered intravenously at a dose of 8 mg/kg every 2 weeks. In each case, tocilizumab alleviated symptoms, including generalized fatigue, pyrexia, and alleviated biochemical abnormalities, including anemia, hypoalbuminemia, hypergammaglobulinemia, and increased C-reactive protein (CRP). Side effects included hypercholesterolemia, acute pyelonephritis, mild inflammation of the parotid glands, and upper respiratory system inflammation. Other severe side effects were not observed. These results indicate that tocilizumab is effective for the treatment of MCD. This is the first report on tocilizumab efficacy for Castleman's disease after approval for use for Castleman's disease.

Therapies that activate the immune system through blocking the binding of programmed death ligand 1 (PD-L1) present on tumors and PD-1 (programmed death 1) present on activated immune cells are revolutionizing the care for patients with cancer. These therapies work by inhibiting negative regulators of the immune system, thereby decreasing a tumor's ability to evade the immune system. The side effects of anti-PD-1/PD-L1 therapies are generally mild and as expected are related to autoimmune reactions. Two of the most common side effects of anti-PD-1/PD-L1 therapies are rash and pruritus occurring in approximately 20% of patients. Although the rash is generally recognized to be immune mediated, the exact mechanisms of the rash remain unclear. Herein, we report three cases of lichenoid dermatitis in three patients treated with MK-3475 (anti-PD-1) that were characterized with marked T-cell infiltrates with few PD-1-positive cells. The rashes in all three patients were relatively mild, allowing treatment to continue despite the rashes. ©2014 American Association for Cancer Research.

The flashlamp pulsed dye laser has been used in the treatment of rhytids. To evaluate the efficacy of the long pulsed dye laser in the treatment of mild to moderate wrinkles in Asian patients. Wrinkles on one half of the face in 10 subjects were treated with the long pulsed dye laser (595 nm, 10 mm spot size, 10 ms, 7 J/cm2, 40 ms spray, 40 ms delay, single-pass, 30% overlap) with the other side serving as a control. A total of three treatments were given at 2 monthly intervals. The following sites were treated: periorbital area, six patients; forehead, two patients; cheek, two patients. No preoperative anesthesia or postoperative treatment were used. Clinical photographs were taken before and after each treatment, and analysis was undertaken through photographic evaluation by non-treating physicians. At 2 months after the last treatment, the clinical improvement of rhytids was noted in all patients compared with baseline. Four subjects had mild improvement (< or = 25%), five had moderate improvement (26-50%) and one had marked improvement (51-75%). The periorbital area was more responsive to treatment compared with the other sites. No clinical changes were noted in the control areas. No adverse effects were reported except for transient mild erythema in two patients which lasted for up to an hour. Nine patients were somewhat satisfied with the treatment and one was highly satisfied. All wanted the other half of the face to be treated. Treatment with a non-ablative 595 nm flashlamp pulsed dye laser can lead to mild to moderate clinical improvement in class I-II rhytids with minimal to no side effects in patients with darker skin types.

Photodynamic therapy (PDT) involves the activation of a previously administered photosensitizing agent by visible light to induce tumor necrosis. Photosensitizers are topically applied in the treatment of skin tumors to avoid systemic side effects. In this study, we evaluated the feasibility and efficacy of aminolevulinic acid (ALA) as a photosensitizer (ALA-PDT) in combination with CO2 laser in the treatment of Bowen's disease (BD; intraepithelial squamous cell carcinoma). Twenty-two lesions from 18 patients were randomized into two groups: 11 lesions were treated with topical ALA-PDT (180 J/cm(2) at 100 mW/cm(2)) + CO2 laser for one to three sessions. The remaining 11 lesions were treated with CO2 laser alone, serving as control group. All patients were reviewed at ≤1-week intervals. Biopsies were taken from BD lesions prior to treatment. The initial evaluation was undertaken 1 month after treatment, and biopsies were harvested for histological evaluation. Patients who did not respond to the three sessions of treatment were referred to surgical treatment. In the ALA-PDT + CO2 laser group, 72.73 % (8/11) of BD lesions showed complete remission, with an overall clearance of 90.91 %, and only one recurred (9 %) during follow-up. Local side effects included mild erythema, edema, erosion, and burning and/or stinging sensation. No systemic side effects were observed. In the control group, 63.63 % (7/11) of lesions had complete remission and the overall clearance was 54.55 %. However, five lesions (45.45 %) had recurrence. Local side effects included mild to moderate edema, erosion, ulceration, delayed healing, prolonged pain, and scarring. There existed a significant difference in recurrence rate between the two groups (P < 0.05). Moreover, after ALA-PDT plus CO2 laser treatment, complete necrosis was observed in responsive lesions, and 3 months later, the atypical BD cells were replaced by normal keratinocytes. Topical ALA-PDT in combination with CO2 laser is safe, effective, and is associated with low recurrence and reduced side effects.

Sinusoidal obstruction syndrome (SOS) is a frequent, troubling, and potentially fatal complication of hematopoietic stem cell transplantation. Despite promising results with defibrotide (DF), no treatment has been established as standard. DF is a single-stranded polydeoxyribonucleotide, obtained from controlled depolymerization of porcine intestinal mucosal cells. It has antithrombotic, antiischemic, antiinflammatory, and thrombolytic properties without significant side effects. We retrospectively evaluated the charts of 80 consecutive patients, with 89 hematopoietic stem cell transplants for hematologic malignancies. The results of early initiation of DF treatment in 14 patients with SOS are presented in this study. Fourteen patients, 8 males and 6 females % median age 40.5 years (range, 16-46 years) were diagnosed to have SOS. Disease severity was classified as severe in 6 (42.85%), moderate in 4 (28.57%), and mild in 4 (28.57%) patients. We treated 14 patients with DF for a median of 21.5 days (range, 4-39 days). All 14 patients received DF after the diagnosis of SOS. Three patients with severe and all of the patients with mild to moderate SOS responded to treatment with complete resolution of SOS-related signs and symptoms. All patients responding to DF were alive at 100 days posttransplantation. There was no significant drug-related side effect among patients treated with DF. With an overall response rate of 78.56% and a 50% complete response rate in severe SOS cases and minimal side effects, we suggest that DF is the best available agent to treat SOS.

To assess the benefit of adjunctive use of a SPF 30 moisturizing lotion in reducing local side effects associated with atopical tretinoin cream. This was a randomized, investigator/evaluator-blinded, split-face comparison in subjects with healthy skin. Subjects applied tretinoin cream 0.05% once daily to the whole face and Cetaphil 174; Dermacontrol Moisturizer (CDM) once daily to one side of the face based on randomization. Tolerability, perference and skin hydration were evaluated at each week, and a cosmetic acceptability questionnaire regarding CDM was completed at the end of the study. The majority (about 83% to 86%) of subjects experienced skin irritations on both sides of their face, though predominantly mild for the CDM + tretinoin treated side. Tolerability preferences favored the CDM+tretinoin sides. Adjunctive use of CDM with a topical tretinoin cream improves tolerance of the treatment.

Androgenetic alopecia (AGA) is undoubtedly the most common form of hair loss in males. It is a condition which may cause cosmetic and psychosocial problems in androgen-dependent cases. In this open, randomized and comparative study we evaluated the efficacy of oral finasteride and 5% topical minoxidil treatment for 12 months in 65 male patients with mild to severe AGA. We randomly assigned 40 (61.53%) patients to receive 1 mg/day oral finasteride for 12 months, and 25 (38.47%) patients applied 5% topical minoxidil solution twice daily for 12 months. There were no significant differences between the 2 groups considering age, age of onset of hair loss, family history and type of hair loss (p > 0.05). In the clinical evaluation at the endpoint of treatment, the clinical cure rates (i.e. increased intensity of hair) were 80% (32/40) for the oral finasteride group and 52% (13/25) for the 5% topical minoxidil group. Encountered side effects were all mild, and there was no need to stop the treatment. In the group given oral finasteride, side effects were noted in 7 patients: 6 patients suffered from loss of libido, and 1 patient had an increase in other body hairs; irritation of the scalp was seen in 1 patient in the group administered 5% minoxidil. These adverse events disappeared as soon as the treatment was stopped. The laboratory data on both drug groups did not show any statistically or clinically significant intragroup changes from baseline values to the endpoint (p > 0.05), except the level of serum total testosterone which was increased, and free testosterone and serum prostate-specific antigen in the finasteride group which were statistically decreased from baseline values to the endpoint (p < 0.05). In this comparative study of systemic finasteride and topical minoxidil, it was concluded that both drugs were effective and safe in the treatment of mild to severe AGA, although oral finasteride treatment was more effective (p < 0.05). Adverse events were not considered important either, and these side effects disappeared as soon as the treatment was stopped.

The frigate His Norwegian Majesty's ship (HNoMS) Fridtjof Nansen was participating in operations in the Gulf of Aden in support of the EU mission tasked with protecting vessels from the threat of piracy. The crew was therefore prioritized and given the first batch of Influenza A (H1N1) vaccine (Pandemrix(®)). To investigate the type, frequency, and intensity of side effects after whole-crew vaccination with Pandemrix vaccine in healthy subjects in a controlled environment. A hundred and thirty-three members of the crew were vaccinated, and then they participated in the study. The side effects of the vaccination were evaluated through a survey. Seventy-five per cent of the vaccinated sailors reported adverse reactions to the vaccine, with 9% not being able to perform their daily duties for one day. Muscle pain, headaches, malaise, and fatigue were the most frequent symptoms reported. The vaccination program using Pandemrix H1N1 vaccine resulted in a high rate of side effects, which were generally mild and resolved within a few days. No serious lasting side effects of the vaccination were reported or registered. The adverse effects of the vaccination did not affect the operational capacity of the vessel.

Anxiety and depression are seen among patients with facial paralysis (FP), but less is known about the exact prevalence. The aim of the current study is to assess the prevalence of anxiety and depressive disorders in the FP population and to investigate possible differences between patients with left- and right-sided FP. Fifty-nine patients with FP and 59 healthy individuals were included in this study between March and December of 2014. The Hospital Anxiety and Depression Scale was used to assess the prevalence of anxiety and depression among these groups. The mean age of the patients and controls was 56 ± 15 and 40 ± 16 years, respectively. Twenty-eight patients had left-sided FP, 30 patients had right-sided FP, and one patient had bilateral FP. In the patient group, approximately 30% had anxiety and 25% had a depressive disorder. Compared with the control group, significantly more patients presented with mild anxiety (p = 0.031), mild depression (p = 0.047), and moderate depression (p = 0.006). No significant differences were found in terms of the prevalence of anxiety between left- and right-sided FP. However, significantly more patients with left-sided FP had mild depression (p = 0.018) than those with right-sided FP. This study found a significant difference in anxiety and depression between patients with FP and healthy controls. No clinically significant difference was noted in the prevalence of anxiety or depression between patients with left- and right-sided FP.

Background: Acne vulgaris, a common human skin condition, is an inflammatory disease characterized by comedones, papules, nodules and possibly scarring. This study aimed to evaluate the efficacy of a combination of 5% dapsone gel plus oral isotretinoin in the treatment of acne vulgaris. Materials and Methods: A randomized, placebo-controlled, study was carried out on patients with moderate to severe acne. The patients were randomly divided in two groups: (dapsone gel and vehicle gel). All Patients were administered oral isotretinoin 20 mg daily and topical gel twice a day for 8 weeks. The Global Acne Assessment Score (GAAS), the number lesions and side-effects were documented at base line and weeks 4, 8 and 12. Results: A total of 58 patients (age range: 18-25 years) were included in our study. The number of lesions was significantly lower in the dapsone-treated group at all follow-up visits (P < 0.001). The mean GAAS score in the dapsone-treated group and in the Placebo-treated group decreased, but there was no statistical difference in two groups (P < 0.001). The side-effects on the dapsone-treated group were a mild burning sensation in 7 patients (24.13%), mild erythema of the skin and mild dryness in 4 (13.79%) and 3 (10.34%) cases respectively (P < 0.001). In our study, adverse effects were common but they were minor and tolerable. No clinically significant changes in laboratory parameters were observed (P < 0.001). Conclusions: Dapsone gel was an effective medication for patients who received isotretinoin for acne vulgaris treatment resulting in a significant reduction of the number of lesions. PMID:25250291

[The treatment of postpartum depression with interpersonal psychotherapy and interpersonal counseling].

PubMed

Stuart, Scott; Clark, Elizabeth

2008-01-01

Perinatal depression is a prevalent disorder with a high degree of morbidity for both mother and infant. There are now empirically validated treatments for both postpartum depression and depression during pregnancy. Among these is Interpersonal Psychotherapy (IPT), which has been shown to be effective for postpartum depression across the spectrum of mild to severe depression. In fact, the limited evidence of efficacy for medication and concern about medication side effects have led some to suggest that IPT should be the first line treatment for depressed breastfeeding women. There are similar concerns about medication usage during pregnancy. Recent clinical and research experience also suggest that Interpersonal Counseling (IPC) may be effective for selected postpartum women as well. IPC, an abbreviated form of IPT, appears to be effective for mild to moderate depression, and has the potential advantage of being more amenable to delivery in primary care or OB settings.

In a prospective single-blind comparative trial, sixty newly diagnosed mild to moderate hypertensives were randomly assigned to either propranolol or hydroflumethiazide monotherapy. Baseline fasting serum glucose lipid profiles, serum uric acid and potassium levels, were determined at the beginning of the trial. Repeat levels were determined at completion of twelve weeks of treatment. Propranolol treatment significantly reduced HDL-cholesterol (p < 0.02) and increased both VLDL and total serum triglycerides (p < 0.01). Hydroflumethiazide significantly increased total and LDL-chole-sterol, fasting serum glucose and uric acid levels (p < 0.01); potassium levels were significantly lowered (p < 0.01). Treatment with either propranolol or hydroflumethiazide is associated with significant metabolic side-effects which require regular monitoring and intervention as appropriate.

The glucose-lowering pharmacopeia continues to grow for patients with type 2 diabetes. The latest drug category, the SGLT2 inhibitors reduce glycated hemoglobin concentrations by increasing urinary excretion of glucose. They are used mainly in combination with metformin and other antihyperglycemic agents, including insulin. Their glucose-lowering potency is modest. Advantages include lack of hypoglycemia as a side effect, and mild reduction in blood pressure and body weight. Side effects include increased urinary frequency, owing to their mild diuretic action, symptoms of hypovolemia, genitourinary infections. There are also recent reports of rare cases of diabetic ketoacidosis occurring in insulin-treated patients. Recently, a large cardiovascular outcome trial reported that a specific SGLT2 inhibitor, empagliflozin, led to a reduction in the primary endpoint of major cardiovascular events. This effect was mainly the result of a surprising 38 % reduction in cardiovascular death, and the drug was also associated with nearly as large a reduction in heart failure hospitalization. These findings were notable because most drugs used in type 2 diabetes have not been shown to improve cardiovascular outcomes. Accordingly, there is growing interest in empagliflozin and the entire SGLT2 inhibitor class as drugs that could potentially change the manner in which we approach the management of hyperglycemia in patients with type 2 diabetes.

The purpose of this study is to study the operative difficulties and success rate of transcanalicular laser-assisted endoscopic dacryocystorhinostomy in patients of chronic dacryocystitis with deviated nasal septum (DNS). A prospective interventional clinical study of 36 consecutive patients suffering from chronic dacryocystitis with nasolacrimal duct obstruction with DNS undergoing primary TCLADCR from March to June 2011 was carried out. Diode laser was used to create a 16-mm(2) ostium which was enlarged to 64 mm(2) using Blakesley's forceps. Success was defined as anatomical patency and absence of symptoms at 12 months of follow-up. Out of the 36 patients, 25 were females with ages 20-72 years, and 19 were left sided. There were 12 high, 12 mid and 12 basal DNS towards the side of surgery, mild to moderate in severity. Intraoperatively there was difficulty in visualising the aiming beam in the nose, tedious manipulation of endoscope and excessive bleeding in 3 patients. Increased bleeding and failures were significantly higher in high DNS (Fisher exact test-2 tailed: 0.0045). The procedure was successful in 94.4 % cases with average ostium size of 21.94 mm(2) at 12 months and no statistically significant difference in success rates between mild and moderate DNS (Fisher exact test-2 tailed: 1.000). Also there was no difference in the complication rate between mild and moderate DNS (Fisher exact test-2 tailed: 0.0841). TCLADCR is an effective procedure in patients with mild to moderate mid and basal DNS and obviates the need for multiple procedures and a cutaneous scar.

The Evolution of the Interstellar Medium in the Mildly Disturbed Spiral Galaxy NGC 4647

We present matched-resolution maps of H I and CO emission in the Virgo Cluster spiral NGC 4647. The galaxy shows a mild kinematic disturbance in which one side of the rotation curve flattens but the other side continues to rise. This kinematic asymmetry is coupled with a dramatic asymmetry in the molecular gas distribution but not in the atomic gas. An analysis of the gas column densities and the interstellar pressure suggests that the H2/H I surface density ratio on the east side of the galaxy is 3 times higher than expected from the hydrostatic pressure contributed by the mass of the stellar disk. We discuss the probable effects of ram pressure, gravitational interactions, and asymmetric potentials on the interstellar medium and suggest it is likely that a m=1 perturbation in the gravitational potential could be responsible for all of the galaxy's features. Kinematic disturbances of the type seen here are common, but the curious thing about NGC 4647 is that the molecular distribution appears more disturbed than the H I distribution. Thus, it is the combination of the two gas phases that provides such interesting insight into the galaxy's history and into models of the interstellar medium.

Acne patients experience not only a medical disease but also an aesthetic condition, and this latter complication greatly motivates patients to seek out the best treatment regimen to hasten improvement in their appearance. The available clinical procedures for acne treatment include salicylic acid 30% peel and pneumatic broadband light (PBBL). The objective of this study was to compare the efficacy of salicylic acid 30% peel and PBBL treatments in patients with mild to moderately severe facial acne vulgaris. Twelve patients were recruited for a 12-week prospective, single-blind, randomized, split-face study. Patients were treated with a salicylic acid 30% peel on one side of the face and PBBL treatment was administered on the opposite side of the face for 6 consecutive weeks without other acne treatments. At every visit, treatment evaluations were performed using a modified Global Acne Grading Score (mGAGS), acne quality of life (QOL) questionnaire, Wong-Baker FACES Pain Rating Scale (WBPRS) assessments, and clinical photography. Improvement in acne symptoms was observed for both treatment procedures without significant differences and with minimal side effects. Salicylic acid 30% peel and PBBL were well tolerated in our study, and both clinical procedures were efficacious and well-tolerated by the patients.

Is electroconvulsive therapy (ECT) effective and safe for treatment of depression in dementia? A short review.

PubMed

Oudman, Erik

Depression is one of the most frequently diagnosed psychiatric disorders in patients with dementia with a prevalence of up to 50%. The detrimental effects of depression in dementia include disability in daily living, worse quality of life, and faster cognitive decline. Although electroconvulsive therapy (ECT) is a well-established and effective treatment for depression in the elderly, it is currently an overlooked treatment option in the elderly with dementia and depression. The aim of this review was to provide a critical analysis of the efficacy and safety of ECT in depression superimposed on dementia by reviewing the current literature on this topic. Current evidence suggests that ECT is an effective treatment for depression in dementia, although the relatively small number of controlled studies hampers the comparison of effectiveness between healthy nongeriatric patients and those with dementia. Moreover, the systematic reports on cognitive side effects are very limited in number and currently only apply to moderately mild or mild dementia of nonvascular origin. Some studies do suggest that cognitive side effects are likely in later stages of dementia and in patients with vascular dementia. It is therefore of crucial relevance to prospectively study effects of ECT in different types and phases of dementia in controlled trials. From a clinical perspective, it is essential to inform and educate patients and family about the possible risks and benefits of ECT treatment for depression in dementia.

The efficacy and side effects of buspirone compared with methylphenidate (MPH) in the treatment of children with attention-deficit/hyperactivity disorder (ADHD). A total of 34 children with ADHD as defined by DSM-IV-TR were randomized to buspirone or methylphenidate dosed on weight-adjusted basis at buspirone (0.5 mg/kg/day) and methylphenidate (0.3-1 mg/kg/day) for a 6-week double-blind clinical trial. The principle measures of outcome were the teacher and parent ADHD Rating Scale. The side effects were assessed by the special side effect checklist of each drug. In both groups, the scores of teacher and parent ADHD Rating Scale significantly declined on the 6th week as compared to baseline (p = 0.001). These effects were observed in the subscales too. No significant differences were observed between the two protocols on the total scores of parent and teacher ADHD Rating Scale, but methylphenidate was superior to buspirone in decreasing the symptoms of inattention. The side effects of buspirone were mild and rare in comparison with MPH. Buspirone has a favorable side-effects profile. It also has clinically and statistically significant impacts on improving the ADHD symptoms in children. These preliminary findings of the efficacy of buspirone in children with ADHD need large and cross-over studies.

Over a period of nine months twenty-five epileptic patients were treated with the oral loading dose of phenytoin. The dose ranged from 12 to 23 mg/kg body weight during 1 to 12 hours. In 20 patients with serial seizures or intolerance to other antiepileptic drugs this treatment was effective. Seizures also stopped in 2 of 4 patients with serial partial motor seizures. These 2 patients required both higher loading dose and faster rate of administration than the other patients. A patient with epilepsia partialis continua failed to respond to the treatment. Patients that received phenytoin through the naso-gastric tube, in respect to oral administration, required higher doses to obtain therapeutic plasma levels of phenytoin. One patient had mild nausea, 3 mild dizziness, and 1 tinitus on the first day of the treatment. There was no correlation between a given dose and the achieved phenytoin plasma levels. In our opinion the therapy with oral loading dose of phenytoin is highly effective in the treatment of serial generalized seizures and rapid antiepileptic drug substitution, and partially effective in the prevention of partial motor seizures. It produces only mild and transient side-effects.

The administration of parnaparin sodium as oral colon-release tablets (CB-01-05 MMX) has been proposed as a novel approach for the treatment of ulcerative colitis (UC). To assess the efficacy and the tolerability of 8 weeks' oral daily administration of 210 mg of parnaparin sodium compared with placebo in subjects treated with stable-doses of oral aminosalicylates. This multicenter, randomized, double-blind proof of concept trial compared the efficacy of CB-01-05 MMX 210 mg tablets to placebo in 141 subjects with mild to moderately active left-sided UC treated with stable-doses of aminosalicylates. The efficacy was assessed by clinical activity index (CAI), endoscopic index (EI) and histological score (HS). A total of 121 subjects (61 in test group and 60 in control group) formed the per protocol (PP) population. After 8 weeks of treatment, clinical remission was achieved in 83.6% of the CB-01-05 MMX group, and in 63.3% in the comparator group (P = 0.011). This effect was also significantly evident in the test group at week 4 (P = 0.028). A significant difference was also detected in rectal bleeding, (disappeared respectively in 75.4% and 55.0%; P = 0.018), and in mucosal friability (recovered respectively in 80.3% and in 56.7%; P = 0.005). CB-01-05 MMX was safe and significantly effective in treating subjects with mild-to-moderate left-sided UC treated with stable-doses of aminosalicylates.

A controlled study was conducted in hypertensive patients to investigate whether captopril can be substituted for the various other antihypertensive drugs (not including diuretics) to reduce side effects and improve the quality of life. Captopril in a twice daily dose of 25-50 mg, was substituted and titrated in 54 patients. Fifty-two patients, matched by age and sex, comprised the control group, and were treated with a variety of agents. During a follow-up of 9 months, 44 of the patients receiving captopril (81%) achieved the goal of supine blood pressure less than 90 mmHg. Captopril was discontinued in two patients due to side effects. Mild proteinuria was observed in two patients. A significant reduction in scores or rates of side effects (numbness, blurred vision, insomnia, vivid dreams, cold extremities, sleepiness, sexual dysfunction and fatigue) and improvement in quality of life (general feeling, mood and concentration) was observed in the study group compared with the control group. Captopril alone in a twice daily dose of 25-50 mg, or in co-treatment with thiazide, provided sustained blood pressure control with minimal side effects and improvement in quality of life compared with the treatment of hypertension with beta-blockers, vasodilators or methyldopa.

Knowledge about cognitive side-effects induced by electroconvulsive therapy (ECT) in depressed elderly patients is sparse. In this study we investigated changes in the cognitive functioning of non-demented elderly depressed patients receiving ECT (n = 62) compared with healthy elderly people (n = 17). Neuropsychological tests were administered at the start of treatment and again within 1 week after treatment. We computed reliable change indices (RCIs) using simple regression methods. RCIs are statistical methods for analyzing change in individuals that have not yet been used in studies of the acute cognitive side-effects of ECT. At the group level, only letter fluency performance was found to be significantly reduced in the ECT group compared with the controls, whereas both groups demonstrated stable or improved performance on all other measures. At the individual level, however, 11% of patients showed retrograde amnesia for public facts post-ECT and 40% of the patients showed a significant decline in neuropsychological functioning. Decline on a measure of delayed verbal anterograde memory was most common. Our findings indicate that there are mild neurocognitive impairments in the acute phase for a substantial minority of elderly patients receiving ECT. Analysis of reliable change facilitated the illumination of cognitive side-effects in our sample.

25 patients with neurological and neuropsychological deficits after a mild ischaemic stroke were treated with nicergoline (Adavin 60 mg/d) versus placebo in a double blind cross-over trial (3 and 3 months). The patients were examined repeatedly by a neurologist and a neuropsychologist using a battery of tests (PPL, AVLT, Benton and Bourdon tests, number-repetition test). On completion of the trial the improvement of neurological signs (mainly cerebellar deficits) and neuropsychological impairments (in particular of attention and manual manipulation difficulties) was found to be more marked after the period of nicergoline treatment than after placebo. No drug-dependent side effects--including the influence on blood pressure--were observed in the whole group treated.

This multiple-dose, double-blind, placebo-controlled, randomized, normal volunteer study compared formulations of ibuprofen/codeine and aspirin/codeine for systemic safety. Vital signs, hematologic, biochemical and urinary parameters, side effects, mood and mental alertness, were monitored. The placebo group had less gastrointestinal side effects and more frequent stools than the active treatment groups. There was statistical evidence for greater adverse effects of aspirin/codeine on mood and mental alertness in comparison to ibuprofen/codeine and placebo. Ibuprofen/codeine had a more favorable adverse effect profile than aspirin/codeine. A mild respiratory and cardiac depressant effect attributable to codeine was evident in all active treatment groups after 7 days of frequent therapy. More work needs to be done to elucidate the factors regulating the development of tolerance to the respiratory and cardiovascular depressant effects of opiates in general, and for codeine in particular.

Chemical peels are used as adjuvants for treatment of facial acne. No well-controlled studies have compared alpha- and beta-hydroxy acid peels in the treatment of mild to moderately severe facial acne. To compare the efficacy of alpha- and beta-hydroxy acid chemical peels in the treatment of mild to moderately severe facial acne vulgaris. Twenty patients were recruited in this split-face, double-blind, randomized, controlled study. An alpha-hydroxy acid (30% glycolic acid) was applied to one-half of the face and a beta-hydroxy acid peel (30% salicylic acid) was applied contralaterally every 2 weeks for a total of six treatments. A blinded evaluator performed quantitative assessment of papules and pustules. Both chemical peels were significantly effective by the second treatment (p<.05) and there were no significant differences in effectiveness between the two peels. At 2 months posttreatment, the salicylic acid peel had sustained effectiveness. More adverse events were reported with the glycolic acid peel after the initial treatment. The glycolic acid and salicylic acid peels were similarly effective. The salicylic acid peel had sustained effectiveness and fewer side effects. Alpha- and beta-hydroxy acid peels both offer successful adjunctive treatment of facial acne vulgaris.

Mulberry leaf is well known for its several biological effects. The purpose of this study was to evaluate the hypolipidemic effect of mulberry leaf in non-diabetic patients with mild dyslipidemia. A within-subjects research design was conducted at the out-patient clinic in Thailand. Twenty-three patients who met the NCEP ATP III criteria guideline for dyslipidemia and failed a 4 week diet therapy were enrolled and assigned to receive three tablets of 280 mg mulberry leaf tablet three times a day before meals for a period of 12 weeks. Routine blood analyses including lipid parameters and liver function tests were performed every 4 weeks. At 4 and 8 weeks of mulberry leaf tablet therapy, triglyceride was significantly decreased by 10.2% (p < 0.05) and 12.5% (p < 0.05), respectively, from baseline. At the end of the study, total cholesterol, triglyceride and LDL were significantly decreased by 4.9% (p < 0.05), 14.1% (p < 0.05) and 5.6% (p < 0.05), respectively, from baseline, whereas HDL was significantly increased by 19.7% (p < 0.05). Even though some patients experienced side effects such as mild diarrhea (26%), dizziness (8.7%) or constipation and bloating (4.3%), mulberry leaf tablet therapy is still capable and safe in reducing cholesterol levels and enhancing HDL in patients with mild dyslipidemia.

Magnetic resonans excluded the presence of pituitary adenoma. Because patient developed a bromocriptine intolerance, the Vitex Agnus Castus (VAC) extract has been introduced. The VAC therapy was effective, with symptoms relief and improvement of hormonal tests. The VAC medicines are indicated for the treatment of premenstrual syndrome (PMS), mastalgia, menstrual disorders and mild hyperprolactinemia. The mechanism of action is not fully understood, but it is related to dopaniergic activity of diterpenes and castacin in VAC. The randomized clinical trials revealed efficacy of VAC extract in the treatmet of hyperprolactinemia, menstrual disorders, PMS and mastalgia. Good tolerability, lack of serious side-effects and drug interactions are the advantages of the VAC preparations. © 2015 MEDPRESS.

Atopiclair (Zarzenda) is a topical non-steroidal anti-inflammatory agent for the treatment of allergic diseases of the skin. Three main ingredients are contained in this product: glycyrrhetinic acid, telmesteine and Vitis vinifera extracts. Other ingredients include: allantoin, alpha-bisabolol, capryloyl glycine, hyaluronic acid, shea butter and tocopheryl acetate. Two previous randomized, double-blind, vehicle-controlled clinical studies provided evidence that Atopiclair is effective in the treatment of atopic dermatitis. This article presents an open, multicenter, sponsor-free, study on the anti-pruritic activity of this product in adult patients with mild-to-moderate atopic dermatitis. The Median Visual Analogue Scale (VAS) values were: at the start of the study (TO), median VAS was 48.5 mm; three weeks later (T1), median VAS was 34.1 mm (-14.4 mm from baseline); six weeks later (T2), median VAS was 24.6 mm (-23.9 mm from baseline). Statistical analysis revealed that differences between TO versus T1, TO versus T2 and T1 versus T2 were highly significant (p<0.001). Side effects (local burning) were relatively common, although mild in severity. On the basis of the results of this study, Atopiclair showed efficacy in relief of pruritus in adult patients with mild-to-moderate atopic dermatitis.

The use of intramuscular adrenaline to treat anaphylaxis is suboptimal, despite being the first-line treatment recommended by national and international anaphylaxis guidelines. Fear of potentially severe side effects may be one of the underlying factors. The aim of this study was to assess the incidence and severity of adverse side effects after the use of adrenaline in anaphylaxis, as well as potential risk factors. Observational study based on a multicenter online registry of cases of adrenaline administration for suspected anaphylaxis. 277 registered valid cases were included: 138 (51.49%) female, median age 29 years (12-47), and 6 children under 2 years with a median age of 9 months (1-21). Side effects occurred in 58 cases (21.64%), with tremors, palpitations, and anxiety being the most frequent. There was a significant association of developing side effects with older age, higher dose of adrenaline, or use of the intravenous route. Potentially severe adverse effects (high blood pressure, chest discomfort, or ECG alterations) occurred only in 8 cases (2.99%); in these cases, no differences were found according to age or adrenaline dose, but again, intravenous administration was associated with more severe adverse events. This study shows that side effects affect less than 1 in 5 patients who receive adrenaline for an anaphylactic reaction, and are usually mild and transient. Therefore, in an emergency situation such as anaphylaxis, restricting adrenaline administration due to potential adverse effects would, in general, not be justified. © 2017 S. Karger AG, Basel.

The changes in the availability of striatal dopamine transporter and dopamine D2 receptor after mild focal ischemia in rats were measured using a small animal positron emission tomography system. Mild focal ischemia was induced by 20-minute middle cerebral artery occlusion. [ 11 C]PE2I binding to dopamine transporter was transiently increased on the ipsilateral side of the striatum at 2 days after middle cerebral artery occlusion. On day 7 and 14 after middle cerebral artery occlusion, [ 11 C]PE2I binding levels were decreased. In contrast, [ 11 C]raclopride binding to dopamine D2 receptor in the ipsilateral striatum had not changed at 2 days after middle cerebral artery occlusion. [ 11 C]Raclopride binding was significantly decreased on the ischemic side of the striatum at 7 and 14 days after middle cerebral artery occlusion. Moreover, on day 1 and 2 after middle cerebral artery occlusion, significant circling behavior to the contralateral direction was induced by amphetamine challenge. This behavior disappeared at 7 days after middle cerebral artery occlusion. At 14 days, circling behavior to the ipsilateral direction (middle cerebral artery occlusion side) was significantly increased, and that to the contralateral direction also appeared again. The present study suggested that amphetamine-induced circling behavior indicated striatal dopaminergic alterations and that dopamine transporter and dopamine D2 receptor binding could be key markers for predicting motor dysfunction after mild focal ischemia.

The Social Side Effects of Acetaminophen

NASA Astrophysics Data System (ADS)

Mischkowski, Dominik

About 23% of all adults in the US take acetaminophen during an average week (Kaufman, Kelly, Rosenberg, Anderson, & Mitchell, 2002) because acetaminophen is an effective physical painkiller and easily accessible over the counter. The physiological side effects of acetaminophen are well documented and generally mild when acetaminophen is consumed in the appropriate dosage. In contrast, the psychological and social side effects of acetaminophen are largely unknown. Recent functional neuroimaging research suggests that the experience of physical pain is fundamentally related to the experience of empathy for the pain of other people, indicating that pharmacologically reducing responsiveness to physical pain also reduces cognitive, affective, and behavioral responsiveness to the pain of others. I tested this hypothesis across three double-blind between-subjects drug intervention studies. Two experiments showed that acetaminophen had moderate effects on empathic affect, specifically personal distress and empathic concern, and a small effect on empathic cognition, specifically perceived pain, when facing physical and social pain of others. The same two experiments and a third experiment also showed that acetaminophen can increase the willingness to inflict pain on other people, i.e., actual aggressive behavior. This effect was especially pronounced among people low in dispositional empathic concern. Together, these findings suggest that the physical pain system is more involved in the regulation of social cognition, affect, and behavior than previously assumed and that the experience of physical pain and responsiveness to the pain of others share a common neurochemical basis. Furthermore, these findings suggest that acetaminophen has unappreciated but serious social side effects, and that these side effects may depend on psychological characteristics of the drug consumer. This idea is consistent with recent theory and research on the context-dependency of neurochemical processes. Finally, public health and legal implications of the social side effects of acetaminophen are discussed.

Chemical peeling is a skin-wounding procedure that may have some potentially undesirable side-effects. The present study is directed towards safety concerns associated with superficial chemical peeling with salicylic acid in various facial dermatoses. The study was a non-comparative and a prospective one. Two hundred and sixty-eight patients of either sex, aged between 10 to 60 years, undergoing superficial chemical peeling for various facial dermatoses (melasma, acne vulgaris, freckles, post-inflammatory scars/pigmentation, actinic keratoses, plane facial warts, etc.) were included in the study. Eight weekly peeling sessions were carried out in each patient. Tolerance to the procedure and any undesirable effects noted during these sessions were recorded. Almost all the patients tolerated the procedure well. Mild discomfort, burning, irritation and erythema were quite common but the incidence of major side-effects was very low and these too, were easily manageable. There was no significant difference in the incidence of side-effects between facial dermatoses (melasma, acne and other pigmentary disorders). Chemical peeling with salicylic acid is a well tolerated and safe treatment modality in many superficial facial dermatoses.

Objective: The aim of this study was to investigate the relationship between patient characteristics and adenosine-related side-effects during stress myocard perfusion imaging (MPI). The effect of presence of adenosine-related side-effects on the diagnostic value of MPI with integrated SPECT/CT system for coronary artery disease (CAD), was also assessed in this study. Methods: Total of 281 patients (109 M, 172 F; mean age:62.6±10) who underwent standard adenosine stress protocol for MPI, were included in this study. All symptoms during adenosine infusion were scored according to the severity and duration. For the estimation of diagnostic value of adenosine MPI with integrated SPECT/CT system, coronary angiography (CAG) or clinical follow-up were used as gold standard. Results: Total of 173 patients (61.6%) experienced adenosine-related side-effects (group 1); flushing, dyspnea, and chest pain were the most common. Other 108 patients completed pharmacologic stress (PS) test without any side-effects (group 2). Test tolerability were similar in the patients with cardiovascular or airway disease to others, however dyspnea were observed significantly more common in patients with mild airway disease. Body mass index (BMI) ≥30 kg/m2 and age ≤45 years were independent predictors of side-effects. The diagnostic value of MPI was similar in both groups. Sensitivity of adenosine MPI SPECT/CT was calculated to be 86%, specificity was 94% and diagnostic accuracy was 92% for diagnosis of CAD. Conclusion: Adenosine MPI is a feasible and well tolerated method in patients who are not suitable for exercise stress test as well as patients with cardiopulmonary disease. However age ≤45 years and BMI ≥30 kg/m2 are the positive predictors of adenosine-related side-effects, the diagnostic value of adenosine MPI SPECT/CT is not affected by the presence of adenosine related side-effects.

Lithium is used commonly to treat bipolar mood disorders. In addition to its primary therapeutic effects in the central nervous system lithium has a number of side effects in the kidney. The side effects include nephrogenic diabetes insipidus with polyuria, mild sodium wasting, and changes in acid/base balance. These functional changes are associated with marked structural changes in collecting duct cell composition and morphology, likely contributing to the functional changes. Over the past few years, investigations of lithium-induced renal changes have provided novel insight into the molecular mechanisms that are responsible for the disturbances in water, sodium, and acid/base metabolism. This includes dysregulation of renal aquaporins, epithelial sodium channel, and acid/base transporters. This review focuses on these issues with the aim to present this in context with clinically relevant features.

The use of psychotropic medications, particularly antidepressants, is common in patients with inflammatory bowel disease (IBD) in spite of a lack of their robust efficacy in this population. This review provides an overview of the use trends of different classes of antidepressant and anti-anxiety medication and their effects on mood, nervous system function, gastrointestinal physiology and immunity drawing from the literature available in the general population, other medical conditions, and when available, patients with IBD. It also covers the evidence base for the actions, efficacy, and potential complications of antidepressants organized by different classes. We conducted a PubMed search of articles relating the different drug classes probed to the terms above in different populations of interest. All types of articles were accepted including case reports and series, open and randomized trials, reviews, and expert opinion. We also examined the reference lists of the publications found. Selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) are the most commonly prescribed agents for anxiety and depression in patients with IBD, though their efficacy for these conditions in the general population are mild to moderate at best. SSRIs are generally well tolerated, though at higher doses, they, like most antidepressant classes, can be associated with activation, serotonergic syndrome, and increased suicidal ideation. TCAs have many more serious side effects but have some shown efficacy for functional GI symptoms. A newer class, the serotonin noradrenergic reuptake inhibitors (SNRIs), can be effective for refractory depression, anxiety and chronic pain syndromes with a side effect profile similar to both SSRIs and more mild manifestations of TCAs. Mirtazapine has moderate efficacy for depression if sedation and weight gain side effects are tolerated and some small support for use in nausea and vomiting. Bupropion targets dopamine and noradrenaline reuptake and has moderate efficacy for depression, and some small support for use in fatigue and smoking cessation. Buspirone has an indication for generalized anxiety disorder though studies show only a minimal benefit. It has some growing evidence for use in functional dyspepsia. Most of these agents have physiological effects on the brain, immune system, and gastrointestinal tract (with the exception of bupropion) hence their therapeutic and side effects manifested in these systems. Antidepressant medications are frequently prescribed for depression, anxiety disorders, and chronic pain syndromes, but overall support for their efficacy is modest at best. Psychological interventions have growing support for having much more robust effects without the side effects of antidepressants and should be considered first-line treatment or at least an adjunct to psychotropic medications for these conditions.

Appetoff: another diet fad.

Appetoff diet patches were diet aids introduced to the public in 1987 and removed from the market in 1988 by the FDA for reasons of fraud. The ingredients were supposedly homeopathic concentrations of plant and mineral products. Although 91.6% of persons in this study who used the product for at least 1 week reported weight loss and mild side effects, no active ingredients could be detected by gas chromatography/mass spectrometry.

Complaints of loss of memory and lack of concentration have been reported by long-term survivors of breast cancer. This mild cognitive impairment (MCI), also called "chemobrain" or "chemofog," has been the subject of a number of studies in the last few years. This cognitive impairment, although usually mild, must be studied to define possible risk factors for its development, and for future research into a preventive or therapeutic treatment approach. Long-term survivors of breast cancer must be followed to detect possible treatment sequelae as soon as possible. Since the number of these long-term survivors has increased in the last years, in part because of more active adjuvant treatments, our knowledge about the long-term side effects of these therapies has also grown.

The inflammatory joint diseases of juvenile inflammatory arthritis (JIA), rheumatoid arthritis (RA) and osteoarthritis (OA): and also mild to moderate joint injury, all require a multidisciplinary approach to management. Intra-articular injections of corticosteroids have been shown to be a very beneficial adjunctive treatment in the management of the above disorders. It is, therefore, important that clinicians have a good understanding of the clinical actions of intra-articular injections. This article explores the pharmacokinetics, pharmacodynamics, and clinical pharmacology of triamcinolone acetonide (TA) and triamcinolone hexacetonide (TH) in JIA, RA, and OA. Literature search of TA and TH articles was conducted using key word searches in the PubMed and Google Scholar databases and through references within found articles. TA and TH intra-articular injections have been shown to provide good clinical benefit for up to 6 months and even longer. TH has been shown to decrease in the expression of citrullinated proteins, the monoclonal antibody F95, and peptidylarginine deiminase 4 in RA synovium. TA and TH intra-articular injections have a low side effect profile which is similar to other corticosteroid. They have minimal to no mineralocorticoid adverse effects and facial flushing 2-3 days post injections is the most common side effect recorded, and in almost all cases is no worse than nuisance. TA and TH are useful adjunct therapies in the management of JIA, RA, OA, and mild to moderate joint injury.

2011-11-16

The availability of new topical preparations for the treatment of left sided ulcerative colitis ulcerosa offers a therapy optimization for many patients. Rectal application of steroids and 5-aminosalicylic acid (5-ASA) is associated with fewer side effects and has a higher therapeutic efficacy in mild to moderate-active left-sided colitis as compared to a systemic therapy. Often it is argued that the patients' compliance is insufficient with a rectal therapy. However, with sufficient information on the proven advantages this is usually not the case. The rectal application of drugs in distal ulcerative colitis is suitable also for the maintenance of remission. Therefore the new therapy guidelines recommend topical therapy more than in former times. Subsequently, these manuscripts focussed specifically on the topical therapy of distal colitis, to elucidate that clear treatment advantages are present in daily practice.

Paradoxical effect of dopamine medication on cognition in Parkinson's disease: relationship to side of motor onset.

PubMed

Hanna-Pladdy, Brenda; Pahwa, Rajesh; Lyons, Kelly E

2015-04-01

Parkinson's disease (PD) is characterized by asymmetric motor symptom onset attributed to greater degeneration of dopamine neurons contralateral to the affected side. However, whether motor asymmetries predict cognitive profiles in PD, and to what extent dopamine influences cognition remains controversial. This study evaluated cognitive variability in PD by measuring differential response to dopamine replacement therapy (DRT) based on hemispheric asymmetries. The influence of DRT on cognition was evaluated in mild PD patients (n = 36) with left or right motor onset symptoms. All subjects were evaluated on neuropsychological measures on and off DRT and compared to controls (n = 42). PD patients were impaired in executive, memory and motor domains irrespective of side of motor onset, although patients with left hemisphere deficit displayed greater cognitive impairment. Patients with right hemisphere deficit responded to DRT with significant improvement in sensorimotor deficits, and with corresponding improvement in attention and verbal memory functions. Conversely, patients with greater left hemisphere dopamine deficiency did not improve in attentional functions and declined in verbal memory recall following DRT. These findings support the presence of extensive mild cognitive deficits in early PD not fully explained by dopamine depletion alone. The paradoxical effects of levodopa on verbal memory were predicted by extent of fine motor impairment and sensorimotor response to levodopa, which reflects extent of dopamine depletion. The findings are discussed with respect to factors influencing variable cognitive profiles in early PD, including hemispheric asymmetries and differential response to levodopa based on dopamine levels predicting amelioration or overdosing.

There are no prospective studies available on the behavior of extraesophageal and esophageal symptoms and treatment-related side effects in patients without effective antireflux medication, receiving the most effective antireflux medication, and after laparoscopic fundoplication. Extraesophageal and esophageal reflux symptoms and treatment-related side effects were assessed in 60 patients while they were on no effective antireflux medication (three-week washout period), after three month of treatment with double-dose esomeprazole, and 3 months after laparoscopic Nissen fundoplication. Esophageal and extraesophageal reflux symptoms, rectal flatulence, and bloating were analyzed with the visual analog scale. In addition, dysphagia, rectal flatulence, and bloating were recorded as none, mild, moderate, or severe. Both extraesophageal and esophageal reflux symptoms decreased after treatment with esomeprazole and were further reduced after fundoplication. Dysphagia and flatulence did not increase from baseline after surgery. Bloating decreased both after treatment with esomeprazole and after fundoplication. In contrast, dysphagia and increased flatus were found more often after surgery than during treatment with esomeprazole. Dysphagia and rectal flatulence were less common during treatment with esomeprazole than at baseline or after surgery. Both extraesophageal and esophageal reflux symptoms decreased after treatment with esomeprazole and were reduced further after fundoplication. Any treatment-related side effect was not increased after surgery when compared to baseline. However, compared to esomeprazole there was more dysphagia and flatulence after fundoplication.

The purpose of the present study was to evaluate the tissue characteristics of plaques with moderate or mild stenosis in the inner and outer curvature of the left anterior descending artery (LAD) using integrated backscatter intravascular ultrasound. We evaluated 66 plaques with moderate stenosis (plaque burden >50% but ≤75%) and 49 plaques with mild stenosis (plaque burden >30% but ≤50%) in 66 patients undergoing percutaneous intervention to the LAD. All plaques were >10mm away from any side branch or previously implanted stents. We divided vessel cross-sections into four quadrants (inner curvature, outer curvature, clockwise lateral side, and counterclockwise lateral side) using the septal branch as a landmark for the inner curvature. We averaged relative lipid area, relative fibrous area, and relative calcified area in minimal lumen area (MLA), three cross-sections proximal to the site of MLA, and three cross-sections distal to the site of MLA. In plaques with moderate stenosis, the relative lipid area in the inner curvature was significantly greater than in the outer curvature and lateral sides, whereas there was no significant difference in plaques with mild stenosis. The present study provides new findings that lipid pool is clustered in the inner curvature and fibrous tissue is clustered in the outer curvature of plaques with moderate stenosis in non-branching LAD lesions.

Ninety nine patients with leukemia and/or related disorders were treated with cefmenoxime (CMX). Among them, 77 patients had severe infections, while other 22 patients did not suffer from infection, but it was expected that they would fall into serious conditions if they were infected. Sixty of the 77 patients who had severe infection were used in the evaluation of effectiveness. The remaining 17 patients were not evaluated because they were subjected to combined treatments of CMX and other therapeutic agents such as other antibiotics, gamma-globulin or interferon. Excellent responses were found in 26 (43.3%) patients and good responses in 12 (20.0%) patients. In total, the rate of effectiveness was 63.3%. Nineteen of the 22 patients who were treated prophylactically with CMX were used in the evaluation of effectiveness, while 3 patients were excluded from the evaluation because peripheral neutrophils were counted to be more than 1,000/mm3 before CMX was administrated, although these 3 patients were used in the final evaluation to examine side effects. In the prophylactic treatment, the rate of effectiveness was 89.5%. The side effects were seen in 4 patients (4/82:4.9%). A different symptom was identified in each patient. These symptoms were skin rash, mild nausea, mild diarrhea and slight elevation of serum bilirubin. Prompt improvements of these symptoms occurred as soon as CMX administration was stopped. These results show that CMX is a therapeutically effective and safe antibiotics for the treatment of severe infections or for the prophylaxis of infections in patients associated with leukemia and/or related disorders.

Common management issues in pediatric patients with mild bleeding disorders.

O'Brien, Sarah H

2012-10-01

Type 1 von Willebrand disease and mild platelet function defects are among the most common disorders seen by pediatric hematologists. The management and prevention of bleeding in these patients can be challenging, as there are limited published data to guide clinical practice, and a complete lack of randomized clinical trials. Desmopressin (DDAVP) and antifibrinolytics are the mainstays of treatment in these patients, yet the optimal dosing and timing of these agents to prevent or resolve bleeding, while minimizing adverse side effects, is sometimes unclear. DDAVP-induced hyponatremia is a particularly under-recognized complication in children with bleeding disorders who undergo surgery. Clinicians need to be aware of local measures that are equally important in treating problems such as epistaxis and surgical bleeding. This review will discuss the published literature and provide practical suggestions regarding four common management issues in the care of children and adolescents with mild bleeding disorders: epistaxis, heavy menstrual bleeding, dental extractions, and tonsillectomy.

Jorgensen, Michael G; Carroll, William B

2002-08-01

A potential side effect of dentist-dispensed home tooth-whitening systems is tooth sensitivity. The authors conducted a randomized prospective double-blind study to determine the incidence of tooth sensitivity after home whitening treatment. Fifty adult subjects used a gel containing 15 percent carbamide peroxide and 0.11 percent fluoride ion; an additional 50 adult subjects used a placebo gel daily for four weeks. Each subject's plaque index score, gingival recession status, caries status, current dentifrice and smoking history were recorded at baseline. The researchers evaluated sensitivity weekly by interview for four weeks. Fifty-four percent of subjects in both test and control groups reported mild sensitivity; 10 percent of test subjects and 2 percent of control subjects reported moderate sensitivity; 4 percent of test subjects and no control subjects reported severe sensitivity. Sensitivity decreased with time; by the second week, no severe sensitivity was reported, and by the fourth week, no moderate sensitivity was reported. The authors found a statistically significant positive correlation between reported sensitivity and gingival recession. They found no statistically significant correlations between sensitivity and any of the other recorded parameters. Mild tooth sensitivity can be expected in approximately one-half of patients who undergo home whitening treatment using the gel studied. Approximately 10 percent of patients may experience moderate sensitivity, and 4 percent of patients may experience severe sensitivity for one to two weeks. Patients with gingival recession appear more likely to experience tooth sensitivity during home whitening treatment. Patients considering home whitening treatment should be advised that mild tooth sensitivity is a common side effect and that severe tooth sensitivity occasionally occurs. If gingival recession is present, the probability of tooth sensitivity increases, and tooth sensitivity tends to decrease as treatment progresses.

Treatment of a mild chronic case of ciguatera fish poisoning with intravenous mannitol, a case study.

PubMed

Mitchell, Gary

2005-03-01

This article describes a recent case of ciguatera poisoning treated with intravenous mannitol. Mannitol has been used with good effect in non-controlled studies in acutely severely poisoned patients, but is not described in the treatment of chronic or milder poisoning. Our patient was a 35-year-old Niuean man who had eaten a ciguatoxic fish two weeks previously. His symptoms were not severe but were very unpleasant and restricted his ability to work. He was given a single dose of mannitol (0.66g/kg) as an intravenous infusion over two hours. His symptoms dramatically improved within 24 hours, and within a few days he felt virtually back to his former self. He experienced no side effects to the mannitol. It is suggested that intravenous mannitol may prove to be a useful treatment for mild to moderate ciguatera poisoning, and for patients who present late for treatment.

To compare time to ovulation, ovulation rates, and side effect profile of traditional and the stair-step protocol for ovulation induction using clomiphene citrate in women with polycystic ovary syndrome (PCOS). We performed a retrospective study of women seeking care for infertility with a diagnosis of PCOS at a university-based infertility clinic from July 2012 to July 2014. We included patients who were resistant to the initial starting dose of 50 mg clomiphene. The primary outcome was time to ovulation. Secondary outcomes included ovulation rates, clinical pregnancy rates, and mild and moderate-to-severe side effects based on dose. For the traditional protocol, higher doses of clomiphene were used each subsequent month if no ovulation occurred. For the stair-step protocol, higher doses of clomiphene were given 7 days after the last dose if no dominant follicles were seen on ultrasonography. Our study had 80% power to detect a 20% difference in ovulation. One hundred nine patients were included in the analysis with 66 (60.6%) in the traditional and 43 (39.4%) in the stair-step protocol. Age and body mass index were similar between groups. The time to ovulation was decreased in the stair-step protocol group compared with the traditional protocol group (23.1±0.9 days vs 47.5±6.3 days). Ovulation rates were increased in the stair-step group compared with the traditional group at 150 mg (16 [37%] vs 8 [12%], P=.004) and at 200 mg (9 [21%] vs 3 [5%], P=.01). Pregnancy rates were similar between groups once ovulation was achieved (12 [18.1%] vs 7 [16.3%], P=.08). The stair-step protocol had an increased incidence of mild side effects (vasomotor flushes, headaches, gastrointestinal disturbance, mastalgia, changes in mood; 18 [41%] vs 8 [12%]), but there was no difference in the incidence of severe side effects (headaches, visual disturbances). For women with PCOS, the stair-step clomiphene protocol is associated with decreased time to ovulation and increased ovulation rates at higher doses when compared with the traditional protocol.

Newer direct-acting antiviral agents have revolutionized the medical management of chronic hepatitis C. In addition to being extremely efficacious, they report very mild adverse drug reactions from experience in clinical trials. However, because they are relatively new on the horizon, postmarketing surveillance studies refining the safety profile are not yet available. We present a case of seizures as a potential side effect of antiviral therapy with sofosbuvir and simeprevir.

Epidural analgesia side effects, co-interventions, and care of women during childbirth: a systematic review.

Mayberry, Linda J; Clemmens, Donna; De, Anindya

2002-05-01

The purpose of this article is to profile research findings targeting the intrapartum care implications of the most common side effects and co-interventions that go along with the use of epidural analgesia during labor. Randomized, controlled trials published in English from 1990 to 2000 that addressed each of the targeted side effects and 3 specified co-interventions were evaluated for inclusion in this report. Side effects such as pruritus, nausea, and hypotension during labor are common, but they are usually mild and necessitate treatment infrequently. However, even with the advent of newer low-dose epidurals, the extent of impaired motor ability remains variable across studies. The incidence of "walking" epidurals during labor is likely to be complicated by multiple factors, including individual patient desires, safety considerations, and hospital policies. In response to risks for a decrease in uterine contractions that could prolong labor, oxytocin augmentation is likely to be administered after epidural analgesia. The use of "delayed" pushing may be an effective way to minimize the risk for difficult deliveries. Upright positioning even when confined to bed may be advantageous and desirable to women; however, additional research to determine actual outcome benefits with epidurals is needed. Implications for further research linked to epidural analgesia also include informed consent, modification of caregiving procedures, and staffing/cost issues.

Physiological and skill demands of 'on-side' and 'off-side' games.

This study investigated the physiological and skill demands of 'on-side' and 'off-side' games in elite rugby league players. Sixteen male rugby league players participated in 'on-side' and 'off-side' games. Both small-sided games were played in a 40- × 40-m playing area. The 'off-side' game permitted players to have 3 'plays' while in possession of the ball. Players were permitted to pass backward or forward (to an 'off-side' player). The 'on-side' game also permitted players to have 3 'plays' while in possession of the ball. However, players were only permitted to pass backward to players in an 'on-side' position. Heart rate and movement patterns (via global positioning system) were recorded continuously throughout both games. Data were collected on the distance covered, number of high-acceleration and velocity efforts, and recovery between efforts. Video footage was also taken to track the performance of the players. Post hoc inspection of the footage was undertaken to count the number of possessions and the number and quality of disposals. In comparison to 'on-side' games, 'off-side' games had a greater number of involvements ("touches"), passes, and effective passes. However, the cognitive demands of 'on-side' games were greater than 'off-side' games. 'Off-side' games resulted in a greater total distance covered, greater distance covered in mild and moderate accelerations, and greater distance covered in low, moderate, and high-velocity efforts. There were also a greater number of short duration recovery periods between efforts in 'off-side' games. The results of this study demonstrate that 'off-side' games provide greater physiological and skill demands than 'on-side' games. 'Off-side' games may provide a practical alternative to 'on-side' games for the development of skill and fitness in elite rugby league players.

A double-blind, multicenter study compared the safety and efficacy of oral betaxolol 10 to 40 mg once daily (n = 68) with propranolol 40 to 160 mg twice daily (n = 73) in the treatment of mild to moderate essential hypertension. Both agents produced significant (P less than 0.01) and comparable reductions in mean supine systolic and diastolic blood pressures (7/11 mm Hg on betaxolol and 9/10 mm Hg on propranolol). Both betaxolol and propranolol significantly (P less than 0.01) reduced mean supine heart rate by 9 beats per minute. Patients achieved a more significant (P less than 0.01) reduction in blood pressure earlier (weeks 2 and 4 of the titration period) with betaxolol. By the end of treatment there was no significant difference in response between treatment groups. A higher incidence of central nervous system side effects (insomnia, bizarre dreams, depression, hallucinations, dizziness), however, was seen with propranolol than with betaxolol. Overall, the data show that in patients with mild to moderate essential hypertension, betaxolol 10 to 40 mg administered once daily is as effective as and better tolerated than propranolol 40 to 160 mg administered twice daily.

A crossover comparison of metoprolol and hydrochlorothiazide has been performed in 20 patients with mild hypertension. Both drugs caused almost identical statistically significant reduction in blood pressure of about 20 mm Hg systolic and 15 mm Hg diastolic. The side effects during active therapy were few and mild, but 5 patients experienced subjective symptoms during the first few days following abrupt withdrawal of metoprolol, namely general malaise, palpitations, headache, sweating and tremor. The symptoms were more pronounced in the standing position and disappeared at once on resumption of beta-blocker therapy, or gradually over 5 - 7 days when placebo tablets were given. In 11 of the 20 patients hydrochlorothiazide produced subnormal serum potassium levels and potassium supplements were given. The serum uric acid level was also significantly increased during hydrochlorothiazide treatment.

A retrospective study was undertaken on 56 dogs treated for nasal tumours by megavoltage radiotherapy with a hypofractionated schedule consisting of four doses of 9 Gy given at intervals of seven days. The dogs were followed until they died or were euthanased. The clinical signs had improved in 53 of the 56 dogs by the end of the treatment schedule. Mild acute radiation side effects were observed in the majority of the dogs but late radiation side effects were rare. Kaplan-Meier survival analysis revealed a median survival time after the final dose of radiation of 212 days. The one- and two-year survival rates were 45 per cent and 15 per cent. Fifty of the dogs were euthanased because the initial clinical signs recurred.

Bain, J; Rachlis, V; Robert, E; Khait, Z

1980-04-01

A male contraceptive trial was undertaken in 23 men using a combination of oral medroxyprogesterone acetate (MPA) and oral methyltestosterone (MeT). The men were divided into four groups according to varying drug dosages and were followed for 15 months (control - 3 months, treatment - 6 months, follow-up - 6 months). The parameters assessed included sperm count and motility, serum gonadotropins and sex steroids, and several biochemical and hematological tests. A questionnaire dealing with side-effects and changes in sexual function was administered intermittently. Although sperm count was suppressed (most dramatically at the highest drug doses, MPA 20mg,MeT 20mg), it was not suppressed to infertile levels. Sperm motility was unaltered; LH was modestly suppressed, FSH was not suppressed; testosterone was suppressed even at low doses; dihydrotestosterone responses were inconsistent. No significant biochemical abnormalities or side-effects occurred although some men experienced mild transient acne, gynecomastia and decreased testicular size. We conclude that in the doses used in this trial, the combination of MPA and MeT is not effective for male contraceptive, purposes and that higher doses may induce severe and undesirable side-effects.

First-trimester surgical abortion is a common procedure. Pain control during this procedure is still an unsolved problem. In this randomized, double-blind placebo-controlled study, women presenting for first-trimester surgical abortion received intramuscular phloroglucinol (4 mL) or placebo (normal saline, 4 mL). Visual analog scales (VAS) for pain immediately and 30 min after the procedure and side effects of the drug were recorded. There was no significant difference between groups in the pain level immediately and 30 min after the procedure; 70.7% of the phloroglucinol group (n=58 cases) and 56.9% of the placebo group (n=58 cases ) reported mild pain; 27.6% and 34.5%, respectively, reported moderate pain; and 1.7% and 8.6%, respectively, reported severe pain. Thirty minutes after the procedure, the median pain score was reduced to 1.3 in both groups. Postoperative side effects were reported, but there was no significant difference between groups for nausea or vomiting and blood pressure. The use of this dose of phloroglucinol, during first-trimester abortion by suction evacuation under local anesthesia with lidocaine, did not relieve pain, but caused no side effects.

Melasma is a common acquired pigmentary disorder marked by irregular hyperpigmented macules or patches and most commonly occurs in women of darker skin color. It is a chronic often-relapsing condition that causes negative psychosocial effects in those affected. Current treatments such as hydroquinone, kojic acid, and retinoids, among others, demonstrate variable efficacy and side-effect profiles. We conducted a comprehensive literature review examining the use of tranexamic acid (TA), a well-known anti-fibrinolytic agent, in the treatment of melasma. TA delivered orally, topically, and through physical methods works via the inhibition of ultraviolet (UV)-induced plasmin activity in keratinocytes. Predefined search terms were entered into PubMed. Articles were then independently screened by two authors to include only those written in the English language and relating to human subjects with at least mild melasma. The search identified 28 articles, 15 of which met the criteria for full review. The review revealed that TA treatment for melasma is equally effective or more effective than other standard therapies and may induce fewer side effects. Our comprehensive review suggests that TA may be a promising treatment option for melasma because of its demonstrated effectiveness alone and in combination with other modalities as well as its limited side-effect profile.

In patients with acute ischemic stroke, whether involvement of the insular cortex influences outcome is controversial. Much of the apparent adverse outcome may relate to such strokes usually being severe. We examined the influence of right and left insular involvement on stroke outcomes among patients from the IST-3 study (Third International Stroke Trial) who had visible ischemic stroke on neuroimaging. We used multiple logistic regression to compare outcomes of left versus right insular and noninsular strokes across strata of stroke severity, on death, proportion dead or dependent, and level of disability (ordinalized Oxford Handicap Score) at 6 months, with adjustment for the effects of age, lesion size, and presence of atrial fibrillation. Of 3035 patients recruited, 2099 had visible ischemic strokes limited to a single hemisphere on computed tomography/magnetic resonance scans. Of these, 566 and 714 had infarction of right and left insula. Six months after randomization, right insular involvement was associated with increased odds of death when compared with noninsular strokes on the left side (adjusted odds ratio, 1.83; 95% confidence interval, 1.33-2.52), whereas the adjusted odds ratio comparing mortality after insular versus noninsular strokes on the left side was not significant. Among mild/moderate strokes, outcomes for right insular involvement were worse than for left insular, but among more severe strokes, the difference in outcomes was less substantial. We found an association between right insular involvement and higher odds of death and worse functional outcome. The difference between right- and left-sided insular lesions on outcomes seemed to be most evident for mild/moderate strokes. URL: http://www.isrctn.com.

Objective Chemotherapy is the standard treatment for small-cell lung cancer (SCLC), and leukopenia is a common side effect. This study assesses whether chemotherapy-induced leukopenia is a predictor of efficacy and whether it is associated with the survival of SCLC patients. Methods A retrospective analysis was conducted on data from 445 patients with SCLC who received standard chemotherapy for 4 to 10 cycles. The World Health Organization grading system classifies leukopenia during chemotherapy as follows: absent (grade 0), mild (grades 1 and 2), or severe (grades 3 and 4). The primary endpoint is overall survival (OS). Results The association between chemotherapy-induced leukopenia and OS was assessed. According to a multivariate Cox model with time-varying covariates, the hazard ratio of death was significantly lower among patients with mild leukopenia than among patients with severe leukopenia at 0.687 (0.506 to 0.943) and 1.414 (1.147 to 1.744), respectively. The median survival was 13 months (95% CI: 11 to 15 months) for patients who did not experience leukopenia, 17 months (95% CI: 14 to 18 months) for those with mild leukopenia, and 14 months (95% CI: 13 to 16 months) for those with severe leukopenia (absent vs. mild vs. severe leukopenia, P=0.047). Conclusion Leukopenia during chemotherapy is associated with the survival of SCLC patients. Mild leukopenia is strongly associated with longer survival time. PMID:23882424

Thiothixene in the treatment of geriatric patients with chronic organic brain syndrome.

Thiothixene was used in a four-week double-blind placebo-controlled study of 42 geriatric patients with chronic organic brain syndrome (psychotic or nonpsychotic). The results, according to several rating measures, showed no significant difference between placebo and thiothixene. Side effects were mild and few. These data support the safety of thiothixene therapy for geriatric patients; however, there is no conclusive evidence of its efficacy in the treatment of chronic organic brain syndrome.

2015-07-01

Use of low-dose ketamine infusions in the emergency department (ED) has not previously been described, despite routine use in perioperative and other settings. Our hypothesis was that a low-dose ketamine bolus followed by continuous infusion would 1) provide clinically significant and sustained pain relief; 2) be well tolerated; and 3) be feasible in the ED. We prospectively administered 15 mg intravenous ketamine followed immediately by continuous ketamine infusion at 20 mg/h for 1 hour. Optional morphine (4 mg) was offered at 20, 40, and 60 minutes. Pain intensity, vitals signs, level of sedation, and adverse reactions were assessed for 120 minutes. A total of 38 patients were included with a median initial numerical rating scale (NRS) pain score of 9. At 10 minutes, the median reduction in pain score was 4, with 7 patients reporting a score of 0. At 60 and 120 minutes, 25 and 26 patients, respectively, reported clinically significant pain reduction (decrease NRS score > 3). Heart rate, blood pressure, respiratory rate, and oxygen saturation remained stable. Mild or moderate side effects including dizziness, fatigue, and headache were common. Patient satisfaction was high; 85% reported they would have this medication again for similar pain. A low-dose ketamine infusion protocol provided significant pain relief with mostly mild side effects and no severe adverse events. Wiley Periodicals, Inc.

Taking side effects into account for HIV medication.

Costanza, Vicente; Rivadeneira, Pablo S; Biafore, Federico L; D'Attellis, Carlos E

2010-09-01

A control-theoretic approach to the problem of designing "low-side-effects" therapies for HIV patients based on highly active drugs is substantiated here. The evolution of side effects during treatment is modeled by an extra differential equation coupled to the dynamics of virions, healthy T-cells, and infected ones. The new equation reflects the dependence of collateral damages on the amount of each dose administered to the patient and on the evolution of the viral load detected by periodical blood analysis. The cost objective accounts for recommended bounds on healthy cells and virions, and also penalizes the appearance of collateral morbidities caused by the medication. The optimization problem is solved by a hybrid dynamic programming scheme that adhere to discrete-time observation and control actions, but by maintaining the continuous-time setup for predicting states and side effects. The resulting optimal strategies employ less drugs than those prescribed by previous optimization studies, but maintaining high doses at the beginning and the end of each period of six months. If an inverse discount rate is applied to favor early actions, and under a mild penalization of the final viral load, then the optimal doses are found to be high at the beginning and decrease afterward, thus causing an apparent stabilization of the main variables. But in this case, the final viral load turns higher than acceptable.

Hyperventilation with and without maintenance of isocapnia: a comparison of selected gasometric and respiratory parameters.

2014-09-15

The aims of this study were to examine selected respiratory and gasometric parameters during hyperventilation with and without isocapnia and to identify the possible mechanism by which isocapnic hyperventilation might be useful in the elimination of volatile substances, including CO. Ten healthy non-smoking volunteers were studied, and each underwent two procedures. During one session, CO2 was added to the respiratory circuit, and during the other session, only 100% O2 was used. The volunteers were coached to hyperventilate until the appearance of side effects. Isocapnic hyperventilation significantly increased alveolar minute ventilation and partial pressure of oxygen in arterialized capillary blood (paO2); to the best of our knowledge, these findings have not previously been reported. Isocapnic hyperventilation was associated with only mild side effects, such as dyspnea, increased respiratory effort and headache, in 30% of subjects. Side effects, including vertigo, paresthesias and muscle tremor, were present in 70% of the volunteers during hyperventilation with 100% O2, and these side effects forced them to limit their respiratory rates and tidal volumes. These increases in alveolar ventilation and the partial pressure of oxygen in the blood may play crucial roles in decreasing the half-time of carboxyhemoglobin, which is the primary goal of the treatment of CO poisoning.

Cannabidiol (CBD), one of the major products of the marijuana plant, is devoid of marijuana's typical psychological effects. In contrast, potential antipsychotic efficacy has been suggested based on preclinical and clinical data (Zuardi et al., 2002). In this report, we further investigated the efficacy and safety of CBD monotherapy in three patients with treatment-resistant schizophrenia (TRS). This was an in-patient study. All patients were given placebo for the initial 5 days, and from the 6th to 35th day (inclusive) they received CBD (initial oral dose of 40 mg reaching 1280 mg/day). On the 36th day, CBD treatment was discontinued and replaced by placebo for 5 days, which was subsequently switched to olanzapine for over 15 days. Efficacy, tolerability and side effects were assessed. One patient showed mild improvement, but two patients didn't show any improvement during CBD monotherapy. All patients tolerated CBD very well and no side effects were reported. These preliminary data suggest that CBD monotherapy may not be effective for TRS.

Second-generation corticosteroids for the treatment of Crohn's disease and ulcerative colitis: more effective and less side effects?

Systemic corticosteroids are highly effective at inducing clinical remission in cases of acute exacerbation of Crohn's disease (CD) and ulcerative colitis (UC); however, their use is limited by their frequent and sometimes severe side effects. Thus, a second generation of corticosteroids with less systemic effects has been developed. This review analyzed all of the studies on the new formulations of steroids with limited absorption (budesonide, budesonide MMX®, beclomethasone dipropionate and erythrocyte-mediated delivery of dexamethasone) in patients with CD and UC. All relevant articles published in English between September 1960 and April 2011 were reviewed. Budesonide is superior to placebo, and as effective as systemic corticosteroids in inducing clinical remission in patients with ileo-colonic CD, but evidence of mucosal healing is limited. When administered as an MMX formula, budesonide can also effectively induce clinical remission in patients with UC, but budesonide alone is not effective in maintaining clinical remission in CD or UC. Beclomethasone dipropionate seems to be effective in patients with mild-to-moderate left-sided and extensive UC, while data on erythrocyte-mediated delivery of dexamethasone are encouraging but still limited. The safety profile for all these products is good but more studies are needed. Steroids remain the mainstay for the induction of clinical remission in cases of acute relapse of both CD and UC. Second-generation corticosteroids are an interesting alternative, with the advantage of high topical activity, less systemic toxicity and limited side effects. Copyright © 2012 S. Karger AG, Basel.

Texture analysis of MR images of patients with Mild Traumatic Brain Injury

PubMed Central

2010-01-01

Background Our objective was to study the effect of trauma on texture features in cerebral tissue in mild traumatic brain injury (MTBI). Our hypothesis was that a mild trauma may cause microstructural changes, which are not necessarily perceptible by visual inspection but could be detected with texture analysis (TA). Methods We imaged 42 MTBI patients by using 1.5 T MRI within three weeks of onset of trauma. TA was performed on the area of mesencephalon, cerebral white matter at the levels of mesencephalon, corona radiata and centrum semiovale and in different segments of corpus callosum (CC) which have been found to be sensitive to damage. The same procedure was carried out on a control group of ten healthy volunteers. Patients' TA data was compared with the TA results of the control group comparing the amount of statistically significantly differing TA parameters between the left and right sides of the cerebral tissue and comparing the most discriminative parameters. Results There were statistically significant differences especially in several co-occurrence and run-length matrix based parameters between left and right side in the area of mesencephalon, in cerebral white matter at the level of corona radiata and in the segments of CC in patients. Considerably less difference was observed in the healthy controls. Conclusions TA revealed significant changes in texture parameters of cerebral tissue between hemispheres and CC segments in TBI patients. TA may serve as a novel additional tool for detecting the conventionally invisible changes in cerebral tissue in MTBI and help the clinicians to make an early diagnosis. PMID:20462439

The success of topically applied treatments on skin relies on the efficacy of skin penetration. In order to increase particle or product penetration, mild skin barrier disruption methods can be used. We previously described cyanoacrylate skin surface stripping as an efficient method to open hair follicles, enhance particle penetration, and activate Langerhans cells. We conducted ex vivo and in vivo measurements on human skin to characterize the biological effect and quantify barrier disruption-related inflammation on a molecular level. Despite the known immunostimulatory effects, this barrier disruption and hair follicle opening method was well accepted and did not result in lasting changes of skin physiological parameters, cytokine production, or clinical side effects. Only in ex vivo human skin did we find a discrete increase in IP-10, TGF-β, IL-8, and GM-CSF mRNA. The data underline the safety profile of this method and demonstrate that the procedure per se does not cause substantial inflammation or skin damage, which is also of interest when applied to non-invasive sampling of biomarkers in clinical trials. © 2018 S.

To systematically review the effectiveness of medical treatment for Cushing's syndrome in clinical practice, regarding cortisol secretion, clinical symptom improvement, and quality of life. To assess the occurrence of side effects of these medical therapies. Eight electronic databases were searched in March 2017 to identify potentially relevant articles. Randomized controlled trials and cohort studies assessing the effectiveness of medical treatment in patients with Cushing's syndrome, were eligible. Pooled proportions were reported including 95% confidence intervals. We included 35 articles with in total 1520 patients in this meta-analysis. Most included patients had Cushing's disease. Pooled reported percentage of patients with normalization of cortisol ranged from 35.7% for cabergoline to 81.8% for mitotane in Cushing's disease. Patients using medication monotherapy showed a lower percentage of cortisol normalization compared to use of multiple medical agents (49.4 vs. 65.7%); this was even higher for patients with concurrent or previous radiotherapy (83.6%). Mild side effects were reported in 39.9%, and severe side effects were seen in 15.2% of patients after medical treatment. No meta-analyses were performed for clinical symptom improvement or quality of life due to lack of sufficient data. This meta-analysis shows that medication induces cortisol normalization effectively in a large percentage of patients. Medical treatment for Cushing's disease patients is thus a reasonable option in case of a contraindication for surgery, a recurrence, or in patients choosing not to have surgery. When experiencing side effects or no treatment effect, an alternate medical therapy or combination therapy can be considered.

Imatinib mesylate (IM), a tyrosine kinase inhibitor, is the treatment of choice in patients with chronic myeloid leukemia (CML). It is considered a very safe drug, with mostly mild and reversible side effects. Lately, it has been suggested that adverse events may occur after a long term. We report a case of a 72-year-old woman diagnosed with blastic phase of Philadelphia chromosome positive CML treated with IM for 28 months. The patient presented first with ascites as a side effect of the drug. When the ascites re-occurred, it was caused by neuroendocrine tumor (NET) with peritoneal carcinomatosis. We believe this is the first case of a NET as a secondary malignancy (SM) after IM treatment. SM have been described in patients on IM before. It is unclear whether these tumors are caused by imatinib or found more easily because of close follow-up.

Eight-five of 816 (10.7%) students attending a primary school in Central Thailand were examined and found infected with Fasciolopsis buski. All of students ate fresh water lily stems and most ate other fresh water plants including caltrop, water cress and morning glory. The 85 students were given praziquantel in randomized single doses of 15, 25 or 40 mg/kg body weight. Side effects were mild and transient and consisted of headache, dizziness, nausea, sleepiness, abdominal discomfort, anorexia, diarrhea, epigastric pain, vomiting and lassitude. Those receiving the highest dosages had more side effects than students in the other 2 groups. Large blisters were observed on the tegument of F. buski passed in feces and this was believed to be caused by the drug. The authors recommend a single dose of praziquantel in a dosage of 15 mg/kg of body weight for the treatment of parasitosis.

Hyperlipidemia, characterized by the abnormal blood lipid profiles, is one of the dominant factors of many chronic diseases such as diabetes, obesity, and cardiovascular diseases (CVD). For the low cost, effectiveness, and fewer side effects, the popularity of using traditional Chinese medicine (TCM) to handle hyperlipidemia is increasing and its role in health care has been recognized by the public at large. Despite the importance of TCM herbs and formulations, there is no comprehensive review summarizing their scientific findings on handling hyperlipidemia. This review summarizes the recent experimental and clinical results of nine representative single Chinese herbs and seven classic TCM formulae that could improve lipid profiles so as to help understand and compare their underlying mechanisms. Most of single herbs and formulae demonstrated the improvement of hyperlipidemic conditions with multiple and diverse mechanisms of actions similar to conventional Western drugs in spite of their mild side effects. Due to increasing popularity of TCM, more extensive, well-designed preclinical and clinical trials on the potential synergistic and adverse side effects of herb-drug interactions as well as their mechanisms are warranted. Hyperlipidemic patients should be warned about the potential risks of herb-drug interactions, particularly those taking anticoagulants and antiplatelet drugs. PMID:25110708

Ginger augmented chemotherapy: A novel multitarget nontoxic approach for cancer management.

Cancer, referred to as the 'disease of civilization', continues to haunt humanity due to its dreadful manifestations and limited success of therapeutic interventions such as chemotherapy in curing the disease. Although effective, chemotherapy has repeatedly demonstrated inadequacy in disease management due to its debilitating side effects arising from its deleterious nonspecific effects on normal healthy cells. In addition, development of chemoresistance due to mono-targeting often results in cessation of chemotherapy. This urgently demands development and implementation of multitargeted alternative therapies with mild or no side effects. One extremely promising strategy that yet remains untapped in the clinic is augmenting chemotherapy with dietary phytochemicals or extracts. Ginger, depository of numerous bioactive molecules, not only targets cancer cells but can also mitigate chemotherapy-associated side effects. Consequently, combination therapy involving ginger extract and chemotherapeutic agents may offer the advantage of being efficacious with reduced toxicity. Here we discuss the remarkable and often overlooked potential of ginger extract to manage cancer, the possibility of developing ginger-based combinational therapies, and the major roadblocks along with strategies to overcome them in clinical translation of such inventions. We are optimistic that clinical implementation of such combination regimens would be a much sought after modality in cancer management. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

1998-12-01

Since cyclosporine A (CsA) had been used in renal transplant recipients, important improvements in short-term and long-term graft survivals have been detected. In spite of these improvements CsA seems to have several adverse effects. First, CsA leads to nephrotoxicity. Moreover, CsA affects the other organs and systems (skin, liver, nervous system, etc.) and causes, increased risks of infections and malignancies. Hypomagnesemia is one of the side effects of CsA therapy, but it is a rare condition in living related donor renal transplant recipients. It may also cause multi-system dysfunction, especially hypocalcemia and hypokalemia, which cannot be corrected without magnesium therapy. In addition, rhabdomyolysis was detected in animals, but it has not been reported in living related donor renal transplant recipients. In this case report, a living related donor renal transplant recipient who suffered from hypomagnesemia and mild rhabdomyolysis due to CsA therapy will be described and discussed.

Mild hypothermia as a treatment for central nervous system injuries: Positive or negative effects

Besides local neuronal damage caused by the primary insult, central nervous system injuries may secondarily cause a progressive cascade of related events including brain edema, ischemia, oxida-tive stress, excitotoxicity, and dysregulation of calcium homeostasis. Hypothermia is a beneficial strategy in a variety of acute central nervous system injuries. Mild hypothermia can treat high intra-cranial pressure following traumatic brain injuries in adults. It is a new treatment that increases sur-vival and quality of life for patients suffering from ischemic insults such as cardiac arrest, stroke, and neurogenic fever following brain trauma. Therapeutic hypothermia decreases free radical produc-tion, inflammation, excitotoxicity and intracranial pressure, and improves cerebral metabolism after traumatic brain injury and cerebral ischemia, thus protecting against central nervous system dam-age. Although a series of pathological and physiological changes as well as potential side effects are observed during hypothermia treatment, it remains a potential therapeutic strategy for central nervous system injuries and deserves further study.

Topical tretinoin is a medication commonly used for acne that has potential application in the long-term treatment of photodamaged skin. However, there are few published data regarding the tolerability of high-dose tretinoin with long-term use. To assess the long-term tolerability of tretinoin 0.1% cream. A randomized, multicentre, double-blind, controlled trial for chemoprevention of keratinocyte carcinomas (i.e. basal cell or squamous cell carcinomas) using topical tretinoin cream to the face and ears was conducted. All participants were veterans and had a history of two or more keratinocyte carcinomas over the previous 5 years. Participants were examined (by a study dermatologist) and interviewed every 6 months (for up to 5.5 years to May 2004). Treatment comprised tretinoin 0.1% cream or vehicle control cream once daily, then twice daily as tolerated. Participants were instructed to step down application frequency to once daily or less if twice daily was not tolerated. The main outcome measures were reported side-effects, frequency of cream application and attendance at study visits. Appropriate data were available for four of the six clinical sites of this trial. Data from 736 randomized participants (mean age 71 years; 97% men) from four clinical sites were analysed. The tretinoin group more commonly reported one or more side-effects at the 6-month follow-up than the control group (61% vs. 42%, P < 0.0001). Side-effects decreased over time in both groups, but to a greater extent in the tretinoin group, and the difference became nonsignificant at 30 months. Burning was the most common side-effect (39% tretinoin vs. 17% control, P < 0.0001). There was no difference in severity of side-effects among those affected. Of the participants who reported burning in either group, most reported mild burning; only 11% of those with burning in the tretinoin group reported it as severe (mild 62% tretinoin vs. 70% placebo; severe 11% vs. 5%; P = 0.4). Itching (24% vs. 16%, P = 0.01) and other local cutaneous reactions (12% vs. 6%, P = 0.01) were also more commonly reported by the tretinoin group at 6 months. There was no difference in numbness (2% vs. 2%, P = 0.9). Participants in the tretinoin group were less likely to apply cream twice daily at 6 months (29% vs. 43%, P = 0.0002). This difference persisted over the entire duration of follow-up. There was little difference between groups in attendance at study visits or completion of telephone interviews (92% vs. 95%, P = 0.06). No unexpected adverse events were reported. Overall, the tolerability level of topical tretinoin was high in this study population, with almost 40% of the tretinoin group reporting no side-effects, and the majority (67%) tolerating at least once-daily dosing at 6-month follow-up. High-dose topical tretinoin is feasible for long-term use in this population.

Premature closure of one coronal skull suture produces a characteristic arching or relative elevation of the superior orbital rim on the involved side. This sign is associated with facial asymmetry, and both signs are usually the most conspicuous features in patients with mild unilateral coronal craniosynostosis. Photographs suggest that at least 9 individuals over 5 generations of the Abraham Lincoln family had premature closure of 1 coronal suture. In 8 males, there was involvement of the left side; in 1 female, there was involvement of the right side.

Corticosteroid treatment in Sydenham's chorea.

Fusco, C; Spagnoli, C

2018-03-01

Sydenham's chorea (SC) is an immune-mediated hyperkinetic movement disorder, developing after group A Beta-hemolytic streptococcal (GABHS) infection. Aside from conventional symptomatic treatment (carbamazepine, valproate, neuroleptics), the use of steroids has also been advocated, mainly in severe, drug-resistant cases or if clinically disabling side effects develop with first line therapies. Based on the description of 5 cases followed in the Child Neurology Unit of Santa Maria Nuova Hospital in Reggio Emilia and on the available medical literature on this topic, we propose considering the use of corticosteroids therapy in children with SC, with the administration of IV methyl-prednisolone followed by oral deflazacort in severe cases and of oral deflazacort alone in mild and moderate degrees of involvement. In our experience this therapy is effective both in the short and long-term period, in different clinical presentations (chorea paralytica, distal chorea, hemichorea, "classic" chorea, association with mood disorder or dyspraxia) and very well tolerated (no significant side effects were recorded).

Treatment of disseminated superficial actinic porokeratosis (DSAP) is poorly standardized. The present review seeks to comprehensively discuss the potential for laser and light modalities in the treatment of DSAP. A systematic review of light and laser treatment modalities was conducted to include 26 cases of patients with DSAP. Systematic review resulted in 14 articles to be included. Photodynamic therapy (PDT) overall was the least successful treatment modality, with clinical improvement seen in a minority of patients (MAL-PDT: N = 9 patients, 33.3% showed improvement; ALA-PDT: N = 3 patients, 0% improvement; hypericin-PDT: N = 2 patients, 0% improvement) after numerous post-procedural side effects of hyperpigmentation, inflammation, erythema, and discomfort. Overall, in the available reports, PDT demonstrates poor outcomes with greater incidence of side effects. The response rates of DSAP lesions treated with lasers were as follows: (Q-switched ruby lasers: N = 2, 100%; CO 2 laser: N = 1, 100%; PDT and CO 2 combination therapy: N = 2, 0-50%; erbium and neodymium YAG lasers: N = 2, 100%; fractional 1927-nm thulium fiber lasers: N = 2, 100%; Grenz rays: N = 1, 100%; and fractional photothermolysis: N = 2, 100%). The side effects of laser therapy were minimal and included mild erythema, slight hyperpigmentation, and moderate edema. Laser therapy is a promising treatment option for DSAP with an excellent side effect profile. However, higher power studies are required to determine optimal guidelines for laser treatment of DSAP.

Mild traumatic brain injury (TBI) persistent post-concussion syndrome (PPCS) and post-traumatic stress disorder (PTSD) are epidemic in United States Iraq and Afghanistan War veterans. Treatment of the combined diagnoses is limited. The aim of this study is to assess safety, feasibility, and effectiveness of hyperbaric oxygen treatments (HBOT) for mild TBI PPCS and PTSD. Thirty military subjects aged 18–65 with PPCS with or without PTSD and from one or more blast-induced mild-moderate traumatic brain injuries that were a minimum of 1 year old and occurred after 9/11/2001 were studied. The measures included symptom lists, physical exam, neuropsychological and psychological testing on 29 subjects (1 dropout) and SPECT brain imaging pre and post HBOT. Comparison was made using SPECT imaging on 29 matched Controls. Side effects (30 subjects) experienced due to the HBOT: reversible middle ear barotrauma (n = 6), transient deterioration in symptoms (n = 7), reversible bronchospasm (n = 1), and increased anxiety (n = 2; not related to confinement); unrelated to HBOT: ureterolithiasis (n = 1), chest pain (n = 2). Significant improvement (29 subjects) was seen in neurological exam, symptoms, intelligence quotient, memory, measures of attention, dominant hand motor speed and dexterity, quality of life, general anxiety, PTSD, depression (including reduction in suicidal ideation), and reduced psychoactive medication usage. At 6-month follow-up subjects reported further symptomatic improvement. Compared to Controls the subjects' SPECT was significantly abnormal, significantly improved after 1 and 40 treatments, and became statistically indistinguishable from Controls in 75% of abnormal areas. HBOT was found to be safe and significantly effective for veterans with mild to moderate TBI PPCS with PTSD in all four outcome domains: clinical medicine, neuropsychology, psychology, and SPECT imaging. Veterans also experienced a significant reduction in suicidal ideation and reduction in psychoactive medication use. PMID:29152209

Low-dose isotretinoin is used to reduce side effects albeit higher relapse. This study aimed to determine the efficacy and safety of fixed-dose 10 mg daily isotretinoin for the treatment of acne. This prospective study was performed between 2011 and 2015. All 150 patients were given 10 mg daily isotretinoin until a cumulative dose of 90-110 mg/kg. The mean age was 26.6 years with 64.7% moderate acne, 29.3% severe, and 6% very severe. The mean cumulative dose was 98.8 ± 6.05 mg/kg. All 150 patients had total clearance with a mean time to clearance of 24.0 weeks. Patients with severe/very severe acne had higher cumulative dosage (102.1 vs. 97.0, P < 0.001) and longer duration to clearance (32.9 weeks vs. 19.1 weeks, P < 0.001). Mild relapse was seen in 4%. The mean time to relapse was 32.3 weeks. Lip dryness was the commonest side effects (100%). Mild transient elevation of liver enzymes was detected in 3.3% and a slight increase of serum lipid in 2.7% with no treatment discontinuation. Fixed-dose 10 mg daily treatment with isotretinoin until a cumulative dose of 90-110 mg/kg is safe with low relapse rate. © 2016 Wiley Periodicals, Inc.

Venous stasis caused by immobility is an important risk factor for deep vein thrombosis following surgery and lower limb trauma, in bed-ridden medical patients, and in high-risk long distance air travelers. A safe and convenient method for reducing venous stasis would be useful in patients while in hospital and after discharge during their rehabilitation. 49 healthy subjects aged 51-76 were seated for 4 hours during which they received mild electrical stimulation of the calf, or sole of the foot (plantar muscles). Popliteal and femoral venous blood flow velocities were measured via doppler ultrasound. The non-stimulated lower extremity served as the simultaneous control. Subjects completed a questionnaire regarding their acceptance and tolerance of the electrical stimulation. There was a significant increase in venous femoral and popliteal blood flow for both calf (p < 0.035, p < 0.003), and plantar muscles (p < 0.0001, p < 0.009) on the stimulated side compared to the unstimulated side. The magnitude of the effect was similar for calf and plantar muscle stimulation. Subjects did not find the experience uncomfortable, and would use an electrical stimulator if told by their physician that they were at risk for developing blood clots. Mild electrical stimulation of the feet, as well as the calf, is a safe effective and convenient method for counteracting venous stasis and therefore has the potential to reduce the risk of deep vein thrombosis and pulmonary embolism for subjects who are immobilized.

Acne vulgaris is the most common skin disease. Local and systemic antimicrobial drugs are used for its treatment. But increasing resistance of Propionibacterium acnes to antibiotics has been reported. In a double-blind clinical trial, 40 patients with mild to moderate acne vulgaris were recruited. one side of the face was treated with Clindamycin Gel 1% and the other side with Azithromycin Topical Gel 2% BID for 8 weeks and then they were assessed. Average age was 21. 8 ± 7 years. 82.5% of them were female. Average number of papules, pustules and comedones was similarly reduced in both groups and, no significant difference was observed between the two groups (P > 0.05, repeated measurs ANOVA). The mean indexes of ASI and TLC also significantly decreased during treatment in both groups, no significant difference was observed between the two groups. (P > 0.05, repeated measurs ANOVA). Also, impact of both drugs on papules and pustules was 2-3 times greater than the effect on comedones. Average satisfaction score was not significant between the two groups (P = 0.6, repeated measurs ANOVA). finally, frequency distribution of complications was not significant between the two groups (P > 0.05, Fisher Exact test). Azithromycin gel has medical impact at least similar to Clindamycin Gel in treatment of mild to moderate acne vulgaris, and it may be consider as suitable drug for resistant acne to conventional topical therapy.

The role of intravenous immunoglobulin in treatment of mucous membrane pemphigoid: A review of literature

PubMed Central

Tavakolpour, Soheil

2016-01-01

Background: Mucous membrane pemphigoid (MMP) is considered an autoimmune blistering disease that predominantly affects mucous membranes. Various treatments are available for controlling the diseases, but not all of them may respond. Materials and Methods: PubMed and Google Scholar were searched for all the associated studies until 2015, using the keywords such as “cicatricial pemphigoid” or “ocular pemphigoid” or “mucous membrane pemphigoid” or “MMP” and “intravenous immunoglobulin” or “IVIg” to find all the relevant studies. The last search update was for September 2, 2015. Among the searched items, only English studies were included in the review. Results: After excluding nonrelevant studies, 13 studies with a total number of seventy patients with MMP who were under treatment with IVIg were analyzed. The 65 patients responded completely, one did not respond, two had partially responded, and the remaining two patients stopped IVIg therapy, which resulted in ocular cicatricial pemphigoid progression. Majority of the studies reported mild adverse effects while two of them did not report any unwanted side effect. The most common side effect was headache, followed by nausea. Most of the patients who had a cessation of IVIg therapy before achieving clinical remission experienced the disease progression. Conclusion: Overall, it can be concluded that IVIg therapy was very helpful in treatment of MMP patients who did not respond to conventional therapy or stopped using them for various side effects. Adverse effects associated with IVIg therapy were considerably lower than conventional therapy that can lead toward treatment with this agent in patients who suffer from severe side effects.

Retinoids are effective suppressors of the phenotypic development of cancer in many animal systems, whether the process is initiated by chemical, physical or viral carcinogens. Cases of cervical intraepithelial neoplasia are excellent for studying the effectiveness of retinoids as chemopreventive agents because the process can be closely followed by serial colposcopic and pathologic (cytology or biopsy) means and changes in the condition safely monitored. We have previously conducted a phase I study of trans-retinoic acid (Tretinoin) given topically by a collagen sponge and cervical cap. A dose of 0.372% was selected for phase II trial. We have treated 20 patients with topical retinoic acid, and a complete response with total regression of disease was obtained in 50%. Systemic and cervical side effects were mild and vaginal side effects moderate but tolerable. These results provide a clinical basis for a randomized, double-blind phase III study to definitely answer the question of whether retinoic acid is an effective chemopreventive agent for cervical cancer.

Central nervous system considerations in the use of beta-blockers, angiotensin-converting enzyme inhibitors, and thiazide diuretics in managing essential hypertension.

PubMed

Gengo, F M; Gabos, C

1988-07-01

The most common mild side effects occurring with use of beta-blockers, thiazide diuretics, and angiotensin-converting enzyme inhibitors for blood pressure control are central nervous system symptoms, specifically lethargy, sedation, and fatigue. These symptoms affect 5% to 10% of patients taking these drugs. The mechanism by which beta-blockers may induce central nervous system effects is uncertain. Relative lipophilicity as a factor affecting penetrance of the blood-brain barrier has not proved to be a reliable predictor of whether the drug will cause such disturbances. Comparisons of atenolol (hydrophilic) and metoprolol (lipophilic) have shown no differences between these drugs with respect to side effects of the central nervous system. The incidence of central nervous system effects with angiotensin-converting enzyme inhibitors is similar to that for most beta-blockers. The precise role of the angiotensin-converting enzyme in the central nervous system is not well defined. Most thiazide diuretics are not associated with major complications of the central nervous system, although electrolyte imbalance may occasionally lead to complaints of neurologic symptoms. Because the incidence of central nervous system effects with these three classes of drugs is so low, concern for the side effects of the central nervous system is not a prime consideration in the choice of an initial antihypertensive agent.

Non-injection routes for allergen immunotherapy: focus on sublingual immunotherapy.

Allergen specific immunotherapy, together with drugs and allergen avoidance, is a cornerstone in the management of respiratory allergy. The non-injection or local routes were developed with the main goal of improving the safety and minimizing the risk of those side effects, which can accompany the injection route. The pure oral route and the bronchial route showed, in the clinical trials, only a marginal efficacy with not negligible side effects. Therefore, these routes are no longer recommended for clinical use. The nasal route proved effective and safe, but its efficacy is strictly limited to the nose. Moreover, the practical problems with administration have made the use of nasal immunotherapy progressively declining. The efficacy of the sublingual route is confirmed by numerous controlled trials, and a meta analysis (in allergic rhinitis). The safety profile, as derived from clinical trials and post marketing surveillance studies, is satisfactory, with mild gastrointestinal complaints being the more frequent side effect reported. Recent studies have also demonstrated that SLIT has a long-lasting effect and a preventive effect on the onset of new skin sensitizations, and interesting data on adherence and mechanisms of action have become recently available. Based on these experimental data, SLIT is now officially accepted as a viable alternative to the subcutaneous route in adults and children. Several points still need to be elucidated, including: mechanisms of action, optimal dosages, and indications in pediatric patients.

The objective of this article is to investigate the effectiveness and safety of photodynamic therapy (PDT) with 3.6 % topical aminolevulinic acid (ALA) and a short incubation time with red light in moderate to severe acne. One hundred and thirty-six patients with moderate to severe acne were treated with 3.6 % topical ALA-PDT for three sessions with an interval of 2 weeks. Patients were evaluated for efficacy and safety on week 2, 4, 6, 8, and 12 after the initial treatment. Most patients showed apparent clearance of acne lesions at the treated site after three sessions. The effective treatment rates were increased after the multiple therapies. The clinical outcomes are the best at 4 weeks after the final treatment. The total effectiveness rate and cure rate of the low-dose ALA-PDT procedure is 92.65 and 47.06 %, respectively. Thirty-one patients and nineteen patients showed apparent exacerbation of acne lesions before the 2nd and 3rd treatment, respectively, but all of them showed good or excellent improvement after a three-course treatment. A few patients showed mild relapse including papules and comedos at 8 weeks after the final treatment. No significant differences are found in the effects of different acne severity and different genders. Adverse reactions are mild and transient. A 3.6 % topical ALA-PDT with a short time incubation with red light is a simple and an effective treatment option for moderate to severe acne with mild side effects in Chinese people.

Marked hypertriglyceridemia in a woman receiving metoprolol succinate.

β-blockers are commonly used therapies after acute myocardial infarction and in the management of congestive heart failure and hypertension. We report a case of a middle-aged woman with a history of mild hypertension who was placed on metoprolol succinate. Before initiation of the β-blocker, her triglyceride level was in the borderline-high range (150-199 mg/dL). On treatment, her triglyceride levels exceeded 1000 mg/dL. She developed fatigue and mild abdominal discomfort but without biochemical evidence of pancreatitis. After discontinuation of metoprolol succinate, her triglyceride levels receded. This case illustrates an uncommon side effect with a very commonly used therapy in clinical practice. Clinicians should closely evaluate medications and/or other therapies in patients presenting with new-onset hypertriglyceridemia especially when levels are sufficiently elevated to pose increased risk of pancreatitis.

A 60-year-old man with a history of hepatic cirrhosis and cardiomyopathy underwent transoesophageal echocardiogram. He received mild sedation and topical lidocaine. During the recovery period the patient developed ataxia and diplopia for about 30 mins, a result of lidocaine toxicity. The patient was administered a commonly used local anaesthetic, a combination of 2% viscous lidocaine, 4% lidocaine gargle and 5% lidocaine ointment topically to the oropharnyx. The total dose was at least 280 mg. Oral lidocaine undergoes extensive first pass metabolism and its clearance is quite dependent on rates of liver blood flow as well as other factors. The patient's central nervous system symptoms were mild and transient but remind us that to avoid adverse side effects, orally administered drugs with fairly high hepatic extraction ratio given to patients with chronic liver disease need to be given in reduced dosages. Even 'Safe' medications need to be carefully administered.

Objective We planned a cross-sectional analysis to determine the frequency and severity of metabolic acidosis in patients taking topiramate while awaiting craniotomy. Methods Eighty patients (18 - 65 years) taking topiramate to control seizures while awaiting elective craniotomy were enrolled. Any signs of metabolic acidosis or topiramate-related side effects were investigated. Blood chemistry levels and arterial blood gases, including lactate, were obtained. The severity of metabolic acidosis was defined according to base excess levels as mild or moderate. Results Blood gas analysis showed that 71% ( n = 57) of patients had metabolic acidosis. The frequency of moderate metabolic acidosis was 56% ( n = 45), while that of mild metabolic acidosis was 15% ( n = 12). A high respiratory rate was reported in only 10% of moderately acidotic patients. Conclusions In patients receiving topiramate, baseline blood gas analysis should be performed preoperatively to determine the presence and severity of metabolic acidosis.

Pulsed dye laser double-pass treatment of patients with resistant capillary malformations.

The pulsed dye laser is an effective and established treatment for port-wine stains and has become the generally accepted standard of care. However, in many cases, complete clearance cannot be achieved as a significant proportion of lesions become resistant to treatment. Multiple passes or pulse-stacking techniques have been used to improve the extent and rate of fading, but concerns over increased adverse effects have limited this clinical approach. In this work, a double-pass technique with the pulsed dye laser has been described, which may allow for increased depth of vascular injury, greater efficacy, and an acceptable risk profile. Our aim was to determine the efficacy and the rate of side-effects for a double-pass protocol with a pulsed dye laser (PDL) to treat patients previously treated with PDL and/or other laser modalities. A retrospective chart review was conducted of 26 patients treated with a minimum of three double-pass treatments alone, or in combination, with single pass conventional PDL. Almost half of the patients (n = 12) showed either a moderate or significant improvement in fading compared to pre-treatment photographs with the double-pass technique. In a further 12 patients, there was a mild improvement. In two patients, there was no change. Sixteen patients developed mild side-effects: blisters (n = 5), dry scabs (n = 11) and transient hyperpigmentation (n = 4). This preliminary experience suggests that a double-pass technique at defined intervals between the first and second treatment with PDL can further lighten some port-wine stains, which are resistant to conventional single-pass treatments. This technique may be a useful addition to the laser treatment of PWS and deserves further scrutiny with randomized prospective studies and histological analysis to confirm the increased depth of vascular injury.

Sentence recognition in noise and perceived benefit of noise reduction on the receiver and transmitter sides of a BICROS hearing aid.

PubMed

Oeding, Kristi; Valente, Michael

2013-01-01

In the past, bilateral contralateral routing of signals (BICROS) amplification incorporated omnidirectional microphones on the transmitter and receiver sides and some models utilized noise reduction (NR) on the receiver side. Little research has examined the performance of BICROS amplification in background noise. However, previous studies examining contralateral routing of signals (CROS) amplification have reported that the presence of background noise on the transmitter side negatively affected speech recognition. Recently, NR was introduced as a feature on the receiver and transmitter sides of BICROS amplification, which has the potential to decrease the impact of noise on the wanted speech signal by decreasing unwanted noise directed to the transmitter side. The primary goal of this study was to examine differences in the reception threshold for sentences (RTS in dB) using the Hearing in Noise Test (HINT) in a diffuse listening environment between unaided and three aided BICROS conditions (no NR, mild NR, and maximum NR) in the Tandem 16 BICROS. A secondary goal was to examine real-world subjective impressions of the Tandem 16 BICROS compared to unaided. A randomized block repeated measures single blind design was used to assess differences between no NR, mild NR, and maximum NR listening conditions. Twenty-one adult participants with asymmetric sensorineural hearing loss (ASNHL) and experience with BICROS amplification were recruited from Washington University in St. Louis School of Medicine. Participants were fit with the National Acoustic Laboratories' Nonlinear version 1 prescriptive target (NAL-NL1) with the Tandem 16 BICROS at the initial visit and then verified using real-ear insertion gain (REIG) measures. Participants acclimatized to the Tandem 16 BICROS for 4 wk before returning for final testing. Participants were tested utilizing HINT sentences examining differences in RTS between unaided and three aided listening conditions. Subjective benefit was determined via the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire between the Tandem 16 BICROS and unaided. A repeated measures analysis of variance (ANOVA) was utilized to analyze the results of the HINT and APHAB. Results revealed no significant differences in the RTS between unaided, no NR, mild NR, and maximum NR. Subjective impressions using the APHAB revealed statistically and clinically significant benefit with the Tandem 16 BICROS compared to unaided for the Ease of Communication (EC), Background Noise (BN), and Reverberation (RV) subscales. The RTS was not significantly different between unaided, no NR, mild NR, and maximum NR. None of the three aided listening conditions were significantly different from unaided performance as has been reported for previous studies examining CROS hearing aids. Further, based on comments from participants and previous research studies with conventional hearing aids, manufacturers of BICROS amplification should consider incorporating directional microphones and independent volume controls on the receiver and transmitter sides to potentially provide further improvement in signal-to-noise ratio (SNR) for patients with ASNHL.

To investigate the therapeutic effect of nanometer silver impregnated dressing on gunshot wounds after being immersed in brine and tapwater in rabbits. Rabbits were randomly divided into two groups after receiving gunshot wounds in both lower limbs. In group 1, the wounded limbs on the experimental side were immersed in brine for 5 h; in group 2, the wounded limbs on experimental side were immersed in tapwater for 5 h. All the wounds were treated with nanometer silver impregnated dressing on the experimental sides, while those of the control sides were treated with vaseline dressing. Biopsy was done after 30 min and 1, 2, 3, 4, 5 h, respectively. In group 1, the onset of inflammation around the wounds of the experimental sides was delayed, the inflammatory response was less serious, and the wounds were dry with less exudation compared to the controls. The mean healing time of the entry wounds on experimental and control sides was (29.4 +/- 6.6) d and (36.3 +/- 6.0) d (P < 0.01), respectively, and that of the exit wounds on experimental and control sides was (20.1 +/- 6.0) d and (27.3 +/- 5.7) d (P < 0.01), respectively. In group 2, only one of the experimental wounds showed mild inflammation, while all of the control wounds showed serious inflammation with much exudation. The mean healing time of the entry wounds on experimentsides was (13.0 +/- 1.52) d, while that on control sides was (16.0 +/- 3.10) d (P < 0.01). The mean healing time of exit wounds on experimental sides was (11.0 +/- 2.75) d, and those of the control sides was (15.6 +/- 2.85) d (P < 0.01). The nanometer silver impregnated dressing can control infection and accelerate healing in gunshot wounds in rabbits.

Abstract Mild traumatic brain injury (TBI) from focal head impact is the most common form of TBI in humans. Animal models, however, typically use direct impact to the exposed dura or skull, or blast to the entire head. We present a detailed characterization of a novel overpressure blast system to create focal closed-head mild TBI in mice. A high-pressure air pulse limited to a 7.5 mm diameter area on the left side of the head overlying the forebrain is delivered to anesthetized mice. The mouse eyes and ears are shielded, and its head and body are cushioned to minimize movement. This approach creates mild TBI by a pressure wave that acts on the brain, with minimal accompanying head acceleration-deceleration. A single 20-psi blast yields no functional deficits or brain injury, while a single 25–40 psi blast yields only slight motor deficits and brain damage. By contrast, a single 50–60 psi blast produces significant visual, motor, and neuropsychiatric impairments and axonal damage and microglial activation in major fiber tracts, but no contusive brain injury. This model thus reproduces the widespread axonal injury and functional impairments characteristic of closed-head mild TBI, without the complications of systemic or ocular blast effects or head acceleration that typically occur in other blast or impact models of closed-skull mild TBI. Accordingly, our model provides a simple way to examine the biomechanics, pathophysiology, and functional deficits that result from TBI and can serve as a reliable platform for testing therapies that reduce brain pathology and deficits.

Objective. To evaluate the therapeutic effects of Disodium Pamidronate (Bonin) on bone pain in multiple myeloma. Method. 18 patients received only chemotherapy and 16 patients with addition of Bonin were compared. Result. The bone pain was significantly relieved both in chemotherapy alone group and in the combination group of Bonin with chemotherapy after treatment (P<0.01, as compared with before therapy). However, the effects of combination group were more dramatical than that of the other group (P<0.05). No obvious side-effects were observed except mild fever in one patient in the combination group. Conclusion. Bonin, as a safe and effective Bisphosphonates preparation, could relieve bone pain in multiple myeloma more effectively when combined with chemotherapy.

Background: Acne vulgaris is the most common disease of the skin affecting adolescents and young adults causing psychological distress. The combination of antibiotic resistance, adverse effects of topical and systemic anti acne medications and desire for high tech approaches have all led to new enthusiasm for light based acne treatment. Intense pulse light (IPL) therapy has three modes of action in acne vulgaris i.e., photochemical, photo thermal and photo immunological. Aims: (1) to study efficacy of IPL therapy in facial acne vulgaris. (2) To compare two fluences - one normal and other subnormal on right and left side of face respectively. Methods: (Including settings and design and statistical analysis used). Total 45 patients in age group 16 to 28 years with inflammatory facial acne vulgaris were included in prospective study. Baseline data for each patient was recorded. All patients were given 4 sittings of IPL at 2 weeks interval and were followed for 2 months every 2 weeks. Fluence used was 35J/cm2 on right and 20J/cm2 on left side. Percentage reduction in lesion count was calculated at each sitting and follow up and graded as mild (0-25%), moderate (26-50%), good (51-75%) and excellent (76-100%). Side effects were noted. The results were analysed using Mann-Whitney Test. Results: On right side, excellent results were achieved in 10(22%), good in 22(49%) and moderate in 13(29%) patients. On left side excellent were results achieved in 7(15%), good in 19(42%) and moderate in 16(43%) patients. There was no statically significant difference noted in efficacy of two fluences used in treatment of facial acne vulgaris. Conclusions: IPL is a effective and safe option for inflammatory acne vulgaris with minimal reversible side effects. Subnormal fluence is as effective as normal fluence in Indian skin. PMID:27688446

Acne vulgaris is the most common disease of the skin affecting adolescents and young adults causing psychological distress. The combination of antibiotic resistance, adverse effects of topical and systemic anti acne medications and desire for high tech approaches have all led to new enthusiasm for light based acne treatment. Intense pulse light (IPL) therapy has three modes of action in acne vulgaris i.e., photochemical, photo thermal and photo immunological. (1) to study efficacy of IPL therapy in facial acne vulgaris. (2) To compare two fluences - one normal and other subnormal on right and left side of face respectively. (Including settings and design and statistical analysis used).

Chemical peeling is a well-identified therapeutic modality for acne vulgaris (AV). Jessner's solution (JS) is a known peeling agent for acne since more than 100 years. Salicylic acid (SA) peel is a well-established peeling agent for acne. There is paucity of literature comparing the current peeling agents of choice, that is, SA with the older peeling agents, that is, JS for acne. To compare the efficacy and safety of 30% SA vs. JS peels in treatment of mild-to-moderate facial acne in Indian patients. A total of 40 patients with mild-to-moderate AV were enrolled for 12 weeks and were randomly divided into two groups: group 1, 30% SA peels and group 2, JS peels were performed 2 weeks apart with total of six peels in 12-week duration. Clinical improvement was assessed objectively using Michaelsson acne scores (MAS) and clinical photographs. Side effects were observed at each visit. At the end of therapy, improvement in MAS and percentage decrease in MAS were significantly higher in group 1 as compared to group 2. Likewise, decrease in mean comedone counts in group 1 was significantly higher as compared to group 2. However, there was no statistically significant difference in the decrease in mean papule and pustule counts between the two groups. Both the groups tolerated the peels well. Thus, 30% SA peels were more effective than JS peels in treatment of noninflammatory lesions, that is, comedones and in overall improvement of mild-to-moderate facial acne vulgaris. © 2016 Wiley Periodicals, Inc.

Drooling is the inability to retain saliva in the mouth and its progression to the digestive tract, being a common problem in pediatric patients with neurological disorders. Three different treatment options are available. To assess the effectiveness and safety of trihexyphenidyl, scopolamine and botulinum toxin infiltration in the treatment of drooling in children with neurological disorders. This is an open and prospective type study. We include patients treated in the Neurology Service that present excessive drooling, affecting their quality of life, between 2009 and 2013. We enrolled 46 patients in the study. The treatment with oral trihexyphenidyl was indicated in 46, obtaining good result in 15 (32.6%), three with temporary effect and the rest with lasting effect. Three patients presented side effects (6.5%). Four out of 11 (36.36%) patients treated with scopolamine patch had beneficial effects. One was withdrawn due to lack of efficacy and six due to side effects. Twenty-five patients were infiltrated with botulinum toxin, with a significant decrease of drooling in 16 patients (64%) after the first injection. We observed no significant changes in nine patients. Only one out of 25 showed side effects (mild dysphagia). Currently there is not a fully effective therapeutic option for drooling. We recommend starting treatment with trihexyphenidyl. A second option could be the scopolamine patch and botulinum toxin as a third option. Botulinum toxin infiltration in salivary glands is shown as an effective and safe alternative in our study.

Alcoholic liver disease or non-alcoholic fatty liver disease/non-alcoholic steatohepatitis are well-known risk factors for liver fibrosis or cirrhosis and hepatocellular carcinoma; it is a major global health concern, but there are few effective and safe management options. Therefore, we aimed to investigate the effects of fermented garlic extracts (FGEs) on hepatic function in adults with mild hepatic dysfunction without underlying hepatic disease. In this double-blind, randomized, placebo-controlled study, seventy-five adults with elevated serum gamma-glutamyl transpeptidase (GGT) levels were included in a FGE-administered group (n = 36) or a placebo group (n = 39), and received either two sachets/day containing FGEs or placebo over a 12-week period. Primary endpoint was the change in serum GGT levels. Data were analysed using a generalized linear mixed effects model. Significant group × time interactions for serum levels of GGT (F = 3.98, P = 0.022) and alanine aminotransferase (ALT; F = 3.28, P = 0.043) were observed with an improvement in levels of GGT (P = 0.066) and ALT (P = 0.014) in the FGE group compared to that reported for the placebo group at the 12-week visits. There was no intergroup difference in the prevalence of adverse events. Intake of FGEs improved serum GGT and ALT levels in adults with mildly elevated serum GGT level without reported adverse side effects. FGEs might be effective and safe management options for mild hepatic dysfunction.

Acute encephalitis with refractory, repetitive partial seizures (AERRPS) is characterized by repetitive seizures during the acute and chronic phases and has a poor neurological outcome. Burst-suppression coma via continuous i.v. infusion of a short-acting barbiturate is used to terminate refractory seizures, but the severe side-effects of short-acting barbiturates are problematic. We report on a 9-year-old boy with AERRPS who was effectively treated with very-high-dose phenobarbital (VHDPB) combined with intermittent short-acting barbiturates. VHDPB side-effects were mild, especially compared with those associated with continuous i.v. infusion of short-acting barbiturates (dosage, 40-75 mg/kg/day; maximum blood level, 290 μg/mL). Using VHDPB as the main treatment, short-acting barbiturates were used intermittently and in small amounts. This is the first report to show that VHDPB, combined with intermittent short-acting barbiturates, can effectively treat AERRPS. After treatment, convulsions were suppressed and daily life continued, but intellectual impairment and high-level dysfunction remained. © 2016 Japan Pediatric Society.

Global population aging will result in increasing rates of cognitive decline and dementia. Thus, effective, low-cost, and low side-effect interventions for the treatment and prevention of cognitive decline are urgently needed. Our study is the first to investigate the effects of Kundalini yoga (KY) training on mild cognitive impairment (MCI). Older participants (≥55 years of age) with MCI were randomized to either a 12-week KY intervention or memory enhancement training (MET; gold-standard, active control). Cognitive (i.e. memory and executive functioning) and mood (i.e. depression, apathy, and resilience) assessments were administered at baseline, 12 weeks and 24 weeks. At baseline, 81 participants had no significant baseline group differences in clinical or demographic characteristics. At 12 weeks and 24 weeks, both KY and MET groups showed significant improvement in memory; however, only KY showed significant improvement in executive functioning. Only the KY group showed significant improvement in depressive symptoms and resilience at week 12. KY group showed short- and long-term improvements in executive functioning as compared to MET, and broader effects on depressed mood and resilience. This observation should be confirmed in future clinical trials of yoga intervention for treatment and prevention of cognitive decline (NCT01983930).

Probiotics and Antibiotic-Associated Diarrhea and Clostridium difficile Infection

NASA Astrophysics Data System (ADS)

Surawicz, Christina M.

Diarrhea is a common side effect of antibiotics. Antibiotics can cause diarrhea in 5-25% of individuals who take them but its occurrence is unpredictable. Diarrhea due to antibiotics is called antibiotic-associated diarrhea (AAD). Diarrhea may be mild and resolve when antibiotics are discontinued, or it may be more severe. The most severe form of AAD is caused by overgrowth of Clostridium difficile which can cause severe diarrhea, colitis, pseudomembranous colitis, or even fatal toxic megacolon. Rates of diarrhea vary with the specific antibiotic as well as with the individual susceptibility.

The speeded performance on simple mental addition problems of 6- and 7-year-old children with and without mild mental retardation is modeled from a person perspective and an item perspective. On the person side, it was found that a single cognitive dimension spanned the performance differences between the two ability groups. However, a discontinuity, or "jump," was observed in the performance of the normal ability group on the easier items. On the item side, the addition problems were almost perfectly ordered in difficulty according to their problem size. Differences in difficulty were explained by factors related to the difficulty of executing nonretrieval strategies. All findings were interpreted within the framework of Siegler's (e.g., R. S. Siegler & C. Shipley, 1995) model of children's strategy choices in arithmetic. Models from item response theory were used to test the hypotheses. Copyright 1999 Academic Press.

Fatigue is the most prevalent and disabling symptom in cancer patients. Yet, scientific literature on this topic is scarce and reports disparate results. This study systematically reviews how fatigue is assessed in patients with low-grade glioma and evaluates its prevalence in LGG patients. A systematic literature search was performed in PubMed, Embase and PsychINFO for articles reporting on fatigue in patients with LGG. Two reviewers independently extracted data from selected articles. Inclusion criteria were: (1) patients with suspected or confirmed LGG; (2) fatigue was assessed as primary or secondary outcome measure; (3) age≥ 18 years; (4) full-length article written in English or Dutch. In total, 19 articles were selected, including 971 patients. Seven self-assessment instruments were identified. Prevalence rates ranged from 39 to 77%. Fatigue was found to be a common side effect of treatment. The prevalence rates ranged from 20 to 76% when fatigue was reported as a mild or moderate side effect and fatigue was prevalent in 4% when reported as a severe side effect. Fatigue is a common problem in LGG patients that warrants more therapeutic and scientific attention. Gaining deeper insight in the underlying mechanisms of fatigue is essential in targeting therapy to individual patients.

This study compared side effects and patient convenience of vaginal progesterone suppositories (Cyclogest) and vaginal progesterone tablets (Endometrin) used for luteal phase support in in vitro fertilization/embryo transfer (IVF/ET) cycles using pituitary downregulation. One hundred and thirty-two infertile patients were randomized on the day of ET by a computer-generated randomization list in sealed envelopes to receive either Cyclogest 400mg or Endometrin 100mg twice daily for 14 days. On days 6 and 16 after ET, they rated side effects and patient convenience into four grades: none, mild, moderate and severe by completing a questionnaire. No significant differences in perineal irritation were found on days 6 and 16 after ET between the two groups, although there was a trend of fewer patients with perineal irritation in the Endometrin group. Significantly more patients in the Endometrin group had difficulty of administration on day 6 after ET. There were no differences in the hormonal profile on day 6 after ET and IVF outcomes between the two groups. There was no difference in perineal irritation after the use of Cyclogest suppositories or Endometrin tablets for luteal phase support although more patients found administration of Endometrin tablets difficult.

In two double-blind, placebo-controlled clinical studies of the nootropic compound acetyl-L-carnitine on the electroencephalogram (EEG) and impaired brain functions of elderly outpatients with mild to moderate cognitive decline of the organic brain syndrome, statistically significant effects could be detected after eight weeks (on the EEG), and after 12 weeks of treatment (on the physician's clinical global impression and the patient-rated level of activities of daily living). Side-effects of acetyl-L-carnitine were generally minor and overall rare. Longer treatment periods and further specifications with regard to the aetiopathology and degree of cognitive impairment are recommended for further clinical studies of this promising compound.

A Dalmatian female presented with a history of vaginal bleeding and was diagnosed as having transmissible venereal tumour (TVT) after cytological examination of the vaginal growth revealed typical TVT cells. A cytology of the aspirate from multiple nodules in the skin near the abdominal and inguinal pair of mammary glands revealed similar cells suggestive of metastasis to skin of mammary region. Chemotherapy was initiated with weekly injections of vincristine sulphate (0.025 mg/kg BW, IV, SID) and haematological examination was performed pre- and post-treatment to assess the prognosis of the patient and side effects of the drug. The major side effects observed during the course of the treatment were high body temperature, mild neutropaenia and significant decrease in packed cell volume, haemoglobin, total leucocyte and erythrocyte count. Four weekly injections of vincristine were administered, and 4 weeks from initiation of treatment, the tumour and nodules were gone, suggesting complete recovery. © 2012 Blackwell Verlag GmbH.

Acute Hepatotoxicity of Intravenous Amiodarone: Case Report and Review of the Literature.

PubMed

Chen, Chia-Chi; Wu, Chien-Chih

2016-01-01

Amiodarone is a class III antiarrhythmic drug widely used for the treatment of both supraventricular and ventricular arrhythmias in intensive care unit. Hepatotoxicity of amiodarone is usually mild and delayed onset. Acute hepatotoxicity is a rare side effect and usually correlated to intravenous form use. In this case, acute hepatocellular injury occurred within 24 hours after the administration of intravenous amiodarone. Liver enzyme significantly improved after holding intravenous amiodarone use. Because ventricular arrhythmia persisted and side effects occurred to alternative therapy, low dose of oral amiodarone was resumed and hepatotoxicity did not occur afterward. Acute hepatotoxicity of intravenous amiodarone is possibly related to polysorbate 80, the solubilizer of amiodarone infusion or higher dose. As a result, when intravenous amiodarone is prescribed, closely monitoring liver enzyme is highly suggested. If acute hepatitis takes place secondary to intravenous amiodarone, oral therapy should not be resumed afterward. If there is no alternative treatment, lower dose of oral amiodarone (≤200 mg/d) could be tried and should monitor liver function regularly.

Long-term safety and efficacy of budesonide in the treatment of ulcerative colitis

PubMed Central

Iborra, Marisa; Álvarez-Sotomayor, Diego; Nos, Pilar

2014-01-01

Ulcerative colitis (UC) is a chronic, relapsing, and remitting inflammatory disease involving the large intestine (colon). Treatment seeks to break recurrent inflammation episodes by inducing and maintaining remission. Historically, oral systemic corticosteroids played an important role in inducing remission of this chronic disease; however, their long-term use is limited and can lead to adverse events. Budesonide is a synthetic steroid with potent local anti-inflammatory effects and low systemic bioavailability due to high first-pass hepatic metabolism. Several studies have demonstrated oral budesonide’s usefulness in treating active mild to moderate ileocecal Crohn’s disease and microscopic colitis and in an enema formulation for left sided UC. However, there is limited information regarding oral budesonide’s efficacy in UC. A novel oral budesonide formulation using a multimatrix system (budesonide-MMX) to extend drug release throughout the colon has been developed recently and seems to be an effective treatment in active left sided UC patients. This article summarizes budesonide’s long-term safety and efficacy in treating UC. PMID:24523594

2015-12-01

Intrathecal baclofen is often used to treat medically intractable spasticity of cerebral or spinal origin. Complications are rare but close monitoring is routinely performed with intrathecal test doses and before pump implantation. We describe a 6 year-old girl with hydranencephaly who underwent an intrathecal baclofen test dose and developed severe bradycardia. A 6 year-old girl with hydranencephaly, quadriplegic cerebral palsy, and severe spasticiityn was a candidate for an intrathecal baclofen pump. She underwent an intrathecal baclofen test dose and within 4 hours developed a heart rate between 30-40 beats per minute and mild hypotension without neurological side effects. Vital signs subsequently normalized, and she was discharged home within 48 hours of admission. Although neurological side effects such as drowsiness and weakness are commonly associated with intrathecal baclofen test doses, attention should also be focused on possible hemodynamic complications including significant bradycardia, especially in vulnerable patients such as those with possible or known hypothalamic dysfunction.

OBJECTIVE To assess if tooth discoloration is a novel side effect of sulfonylurea therapy in patients with permanent neonatal diabetes due to mutations in KCNJ11. RESEARCH DESIGN AND METHODS A total of 67 patients with a known KCNJ11 mutation who had been successfully transferred from insulin injections onto oral sulfonylureas were contacted and asked about the development of tooth discoloration after transfer. RESULTS Altered tooth appearance was identified in 5 of the 67 patients. This was variable in severity, ranging from mild discoloration/staining (n = 4) to loss of enamel (n = 1) and was only seen in patients taking glibenclamide (glyburide). CONCLUSIONS These previously unreported side effects may relate to the developing tooth and/or to the high local concentrations in the children who frequently chewed glibenclamide tablets or took it as a concentrated solution. Given the multiple benefits of sulfonylurea treatment for patients with activating KCNJ11 mutations, this association warrants further investigation but should not preclude such treatment.

To evaluate the efficacy and safety of percutaneous polidocanol injection (PPI) in treating cystic thyroid nodules. A total of 158 cystic or predominantly cystic thyroid nodules (>80% cystic component) in 143 patients were evaluated. 114 patients with compressive symptoms or aesthetic complaints were offered PPI. 44 individuals without compressive symptoms and aesthetic complaints who were only followed up clinically were used as the control group. The efficacy and safety of PPI were evaluated for 1 month, 3 months, 6 months, 9 months, and 12 months of follow-up. In the PPI group, the mean baseline volume of 15.6 ± 18.9 cm 3 reduced at the 1-month follow-up to 5.1 ± 5.6 cm 3 ( p < 0.001) and 0.6 ± 0.9 ( p < 0.001), and nodules shrunk according to the time after PPI ( p < 0.001). A complete response (if ≥70% decrease) to PPI at the 12-month follow-up occurred in 100% of the cystic or predominant cystic nodules. None of the nodules recurred at the 12-month follow-up after PPI. The side effects were mild. Twenty patients (17.5%) developed mild localized pain, and fourteen cases (12.3%) experienced mild or moderate fever after PPI. PPI is a safe and effective alternative to treat benign cystic or predominant cystic thyroid nodules.

To compare serratus anterior and lower trapezius muscle thickness between swimmers with and without current shoulder pain, and between sides when measured by real-time ultrasound imaging. A single blinded age and gender-matched case-control study with 26 symptomatic and 26 asymptomatic recreational swimmers. Muscle thickness of serratus anterior and lower trapezius were measured using previously validated real-time ultrasound imaging protocols. Serratus anterior thickness was measured in side lying with 90° of glenohumeral flexion at rest and during a scapular protraction contraction. Lower trapezius thickness was measured in prone with 145° of glenohumeral abduction whilst at rest and when holding the weight of the arm. There was no statistically significant difference between the muscle thickness of serratus anterior and lower trapezius between the symptomatic shoulder and the dominance-matched shoulder in the asymptomatic group of swimmers. There was also no significant difference in muscle thickness between the symptomatic side and asymptomatic side within the symptomatic group. There appears to be no difference in serratus anterior and lower trapezius thickness between swimmers who have mild to moderate shoulder pain, who continue to swim and those who do not have shoulder pain. When imaging the serratus anterior and lower trapezius in swimmers with mild shoulder pain, clinicians should expect no differences between sides. If muscle thickness differences between sides are detected in recreational swimmers, this may indicate that the swimmer is participating in other asymmetrical activities or has a higher level of shoulder pain.

Brandes, Mirko; Elvers, Sebastian

2017-10-01

The purpose of this study was to determine the impact of mild vs. strongly pushed coach feedback on the physiological response, ratio of perceived exertion (RPE), and time-motion characteristics in soccer training with small-sided games (SSGs). Sixteen elite youth soccer players (aged 17.2 ± 0.7 years, V[Combining Dot Above]O2max 62.1 ± 3.8 ml·kg·min) played two 4 vs. 4 small-sided games each. In random order, the coach provided a mild, unobtrusive, or a strongly pushed feedback throughout the game. Physiological measurements included heart rate expressed in mean values and intensity zones, blood lactate concentration, and RPE. The distance traveled, number of sprints, and work:rest ratio were captured by global positioning systems at 5 Hz. Game performance, such as volume of play and efficacy index, was estimated using the Team Sports Assessment Procedure. No differences were found for the physiological response and time-motion characteristics, but effect sizes demonstrated an increase in RPE (+0.4, p = 0.27) and a decrease in game performance (e.g., volume of play, -2.5, p = 0.08) under pushed feedback. Although a pushed feedback raises RPE, it negatively affected the players' game performance, without necessarily provoking higher physiological responses. These results should help coaches to understand that modifying the type of feedback provided during SSG does not impact the physiological response if SSG are already played with high intensity but that the feedback affects RPE and game performance. To keep a better game performance, soccer coaches are encouraged to provide smooth feedback during SSG.

Evaluation of ketogenic diet (KD) therapies for seizure control during pregnancy when safety and appropriate management become considerations. Until now, no information has been available on seizure reduction and human pregnancy related outcomes in women treated with KD therapies. We describe two cases of pregnant women with epilepsy treated with KD therapy either as monotherapy (Case 1) or as adjunctive therapy (Case 2). Case 1: A 27 year old woman, gravida1, started the classic KD with medium chain triglyceride (MCT) emulsion and 75g carbohydrate-restriction, later reduced to 47g. Glucose levels were 4-6mmol/L and blood ketone levels ranged from 0.2 to 1.4mmol/L. Seizure frequency decreased and seizure-free days increased. Mild side effects included intolerance to MCT, reduced serum carnitine and vitamin levels, and mild hyperlipidemia. Fetal and neonatal growth was normal as was growth and development at 12 months. Case 2: A 36 year-old nulliparous woman was treated with a 20 gram carbohydrate-restricted Modified Atkins Diet (MAD) and lamotrigine, resulting in reduction of seizure frequency to once per month prior to pregnancy. Once pregnant, carbohydrates were increased to 30g. When seizures increased, lamotrigine dose was doubled. Urine ketones trended down during second trimester. A male was born with bilateral ear deformities of unknown significance. The child had a normal neurodevelopment at eight months. Non-pharmacological epilepsy therapies like KD and MAD may be effective during human pregnancy. However, safety still has to be established. Further monitoring to identify potential long term side effects is warranted. Copyright © 2017 British Epilepsy Association. All rights reserved.

The first 50 patients (Regime 1) ingested 1 bisacodyl tablet twice a day 3 days before CTC and 1 dose each of 50 ml of barium and 20 ml of iodinated contrast per day starting 2 days before CTC. The second 50 patients (Regime 2) ingested 3 doses of iodinated contrast over 24 h prior to CTC. Volumes of residual stool and fluid, and the effectiveness of stool and fluid tagging, were graded according to methods established by Taylor et al (Taylor S, Slaker A, Burling D, Tam E, Greenhalgh R, Gartner L, et al. CT colonography: optimisation, diagnostic performance and patient acceptability of reduced-laxative regimens using barium-based faecal tagging. Eur Radiol 2008; 18: 32-42). A 3 day low-residue diet was taken by both cohorts. Questionnaires rating the side-effects and burden of the bowel preparation were compared to a control cohort of patients undergoing barium enema. The proportion of colons producing none/scattered stool (score 1) was 90.3% with Regime 1 and 65.0% with Regime 2 (p<0.005). Any residual stool was significantly better tagged with Regime 1 (score 5), with 91.7% of Regime 1 exhibiting optimum tagging vs 71.3% of Regime 2 (p<0.05). No significant differences in side-effects between the bowel preparation regimes for CTC were elicited. Bowel preparation for barium enema was tolerated significantly worse than both of the CTC bowel preparation regimes. Regime 1, containing a 3 day preparation of a mild laxative, barium and iodine, produced a significantly better prepared colon, with no difference in patient acceptability.

Crossed aphasia has been reported mainly as post-stroke aphasia resulting from brain damage ipsilateral to the dominant right hand. Here, we described a case of a crossed nonfluent/agrammatic primary progressive aphasia (nfvPPA), who developed a corticobasal syndrome (CBS). We collected clinical, cognitive, and neuroimaging data for four consecutive years from a 55-year-old right-handed lady (JV) presenting with speech disturbances. 18-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) and DaT-scan with (123)I-Ioflupane were obtained. Functional MRI (fMRI) during a verb naming task was acquired to characterize patterns of language lateralization. Diffusion tensor MRI was used to evaluate white matter damage within the language network. At onset, JV presented with prominent speech output impairment and right frontal atrophy. After 3 years, language deficits worsened, with the occurrence of a mild agrammatism. The patient also developed a left-sided mild extrapyramidal bradykinetic-rigid syndrome. The clinical picture was suggestive of nfvPPA with mild left-sided extrapyramidal syndrome. At this time, voxel-wise SPM analyses of (18)F-FDG PET and structural MRI showed right greater than left frontal hypometabolism and damage, which included the Broca's area. DaT-scan showed a reduced uptake in the right striatum. FMRI during naming task demonstrated bilateral language activations, and tractography showed right superior longitudinal fasciculus (SLF) involvement. Over the following year, JV became mute and developed frank left-sided motor signs and symptoms, evolving into a CBS clinical picture. Brain atrophy worsened in frontal areas bilaterally, and extended to temporo-parietal regions, still with a right-sided asymmetry. Tractography showed an extension of damage to the left SLF and right inferior longitudinal fasciculus. We report a case of crossed nfvPPA followed longitudinally and studied with advanced neuroimaging techniques. The results highlight a complex interaction between individual premorbid developmental differences and the clinical phenotype.

An image-guided robotic stereotactic radiosurgery (SRS) system can be used to deliver curative-intent radiation in either single fraction or hypofractionated doses. Medical records for 19 dogs with nonlymphomatous nasal tumors treated with hypofractionated image-guided robotic stereotactic body radiotherapy (SBRT), either with or without adjunctive treatment, were retrospectively analyzed for survival and prognostic factors. Median survival time (MST) was evaluated using Kaplan-Meier survival curves. Age, breed, tumor type, stage, tumor size, prescribed radiation dose, and heterogeneity index were analyzed for prognostic significance. Dogs were treated with three consecutive-day, 8-12 gray (Gy) fractions of image-guided robotic SBRT. Overall MST was 399 days. No significant prognostic factors were identified. Acute side effects were rare and mild. Late side effects included one dog with an oronasal fistula and six dogs with seizures. In three of six dogs, seizures were a presenting complaint prior to SBRT. The cause of seizures in the remaining three dogs could not be definitively determined due to lack of follow-up computed tomography (CT) imaging. The seizures could have been related to either progression of disease or late radiation effect. Results indicate that image-guided robotic SBRT, either with or without adjunctive therapy, for canine nonlymphomatous nasal tumors provides comparable survival times (STs) to daily fractionated megavoltage radiation with fewer required fractions and fewer acute side effects.

Aims Intravenous (IV) iron infusions have been associated with hypophosphataemia (HP) and hypersensitivity reactions (HSRs). No studies have compared the side effects of ferric carboxymaltose (FCM) with those of isomaltoside 1000 (ISM). This study aimed to describe the occurrence of HP and HSRs following the administration of either FCM or ISM. Methods Data on 231 outpatients treated with IV iron infusions, between November 2011 and April 2014, were collected. During that period, the department made a switch from FCM to ISM and then back to FCM. Of the 231 patients, 39 received both FCM and ISM during the period. The prevalences of HP and HSRs were compared between the two drugs. Results We found more HP events when FCM was given (64 vs. 9; P < 0.01). In contrast, more patients had mild HSRs when ISM was given (2.5% vs. 10.7%; P < 0.01). A comparison of the two drugs in the subpopulation who received both drug types (n = 39) revealed a difference in phosphate decrease (P < 0.01), with the most marked decrease occurring with FCM. Nine patients who had HSRs were exposed to both drugs. No potential HSR crossover between the two drugs was found. Conclusion We found a higher risk of HP with FCM administration when compared to ISM administration. Conversely, we found a higher risk of mild HSRs with ISM administration when compared to FCM administration. The impacts of the two types of side effects should be considered when choosing an IV iron drug. PMID:27859495

Background While community distribution of topical repellents has been proposed as an additional malaria control intervention, the safety of this intervention at the population level remains poorly evaluated. We describe the safety of mass distribution of the picaridin repellent during a cluster-randomised trial in rural Cambodia in 2012–2013. Methods The repellent was distributed among 57 intervention villages with around 25,000 inhabitants by a team of village distributors. Information on individual adverse events, reported by phone by the village distributors, was obtained through home visits. Information on perceived side effects, reported at the family level, was obtained during two-weekly bottle exchange. Adverse events were classified as adverse reactions (events likely linked to the repellent), cases of repellent abuse and events not related to the repellent use, and classified as per Common Terminology Criteria for Adverse Events. Findings Of the 41 adverse events notified by phone by the village distributors, there were 22 adverse reactions, 11 cases of repellent abuse (6 accidental, 5 suicide attempts) and 8 non-related events. All adverse reactions were mild, occurred in the first few months of use, and mainly manifested as skin conditions. Of the 11 cases of abuse, 2 were moderate and 2 life-threatening. All cases with adverse reactions and repellent abuse recovered completely. 20% of families reported perceived side effects, mainly itching, headache, dizziness and bad smell, but few discontinued repellent use. Conclusions Adverse reactions and abuse during mass use of picaridin were uncommon and generally mild, supporting the safety of the picaridin repellent for malaria control. PMID:28339462

Introduction Venom immunotherapy (VIT) is recommended as the first-line treatment for patients allergic to Hymenoptera venom. Aim To analyze the safety and efficacy of VIT in a real life setting. Material and methods One hundred and eighty patients undergoing VIT were studied to evaluate the safety, efficacy, incidence and nature of symptoms after field stings and adverse reactions to VIT. Results Significantly more patients were allergic to wasp than bee venom (146 vs. 34, p < 0.0001). Early and late side effects were more common during the maintenance (48 patients, 26.7%) than during the induction of VIT (32 patients, 17.8%), were more frequent in patients allergic to bees, and were not associated with angiotensin convertase inhibitors (ACEi) or β-adrenergic antagonists use. Systemic reactions were observed in 4 individuals on wasp VIT (2.7%) and in 6 patients allergic to bees (17.65%). The VIT was efficacious as most patients reported no reactions (50%) or reported only mild local reactions (43.75%) to field stings. The decrease in sIgE at completion of VIT correlated with the dose of vaccine received (r = 0.53, p = 0.004). Beekeeping (RR = 29.54, p < 0.0001) and female sex (RR = 1.27, p = 0.033) were associated with a higher risk of venom allergy. Conclusions Venom immunotherapy is highly efficacious and safe as most of the adverse events during the induction and maintenance phase are mild and local. Side effects of VIT are more common in subjects on bee VIT. Beekeeping and female sex are associated with a higher risk of allergy to Hymenoptera venom. PMID:28507496

We review our recently obtained data on the employment of Si nanoparticles as sensitizers of radiofrequency (RF) - induced hyperthermia for mild cancer therapy tasks. Such an approach makes possible the heating of aqueous suspensions of Si nanoparticles by tens of degrees Celsius under relatively low intensities (1-5 W/cm2) of 27 MHz RF radiation. The heating effect is demonstrated for nanoparticles synthesized by laser ablation in water and mechanical grinding of porous silicon, while laser-ablated nanoparticles demonstrate a remarkably higher heating rate than porous silicon-based ones for the whole range of the used concentrations. The observed RF heating effect can be explained in the frame of a model considering the polarization of Si NPs and electrolyte in the external oscillating electromagnetic field and the corresponding release of heat by electric currents around the nanoparticles. Our tests evidence relative safety of Si nanostructures and their efficient dissolution in physiological solutions, suggesting potential clearance of nanoparticles from a living organism without any side effects. Profiting from Si nanoparticle-based heating, we finally demonstrate an efficient treatment of Lewis Lung carcinoma in vivo. The obtained data promise a breakthrough in the development of mild, non-invasive methods for cancer therapy.

Atopic dermatitis (AD) is a common chronic relapsing disease particularly affecting children. The emollient used for protection of skin barrier function is the standard treatment for patients with AD. Currently, there is a growing interest in the use of nonsteroidal anti-inflammatory agents such as dexpanthenol (vitamin B5) as an alternative treatment. To compare the effectiveness of 5% dexpanthenol (DT) ointment with 1% hydrocortisone (HC) ointment in childhood AD therapy. Patients were treated topically with 5% DT ointment on the right side of the body and 1% HC ointment on the other side twice daily for 4 weeks. The clinical responses were evaluated by SCORAD (Scoring Atopic Dermatitis index) with statistical analysis using paired t-test. Of the 30 children enrolled, 26 completed the protocol; mean age was 7.19 years. The average baseline SCORAD score of the DT-treated side and the HC-treated side was 30.95 and 30.54, respectively. There was no statistically significant difference in SCORAD score reduction between the 2 agents. The edematous score of the HC-treated side exhibited faster resolution than that of the DT-treated side, with a statistically significant difference at week 1 and without a statistically significant difference at weeks 2 to 4. The lichenification response rate of HC treatment was more rapid than that of DT treatment; however, there was no statistical group difference. No adverse events were observed with either agent. The effectiveness of 5% DT ointment is equal to that of 1% HC ointment. DT ointment may be used as alternative treatment in mild to moderate childhood AD therapy.

To improve information for patients and to facilitate a vaccination coverage that is in line with the EU and World Health Organization goals, we aimed to quantify how vaccination and patient characteristics impact on influenza vaccination uptake of elderly people. An online discrete choice experiment (DCE) was conducted among 1261 representatives of the Dutch general population aged 60 years or older. In the DCE, we used influenza vaccination scenarios based on five vaccination characteristics: effectiveness, risk of severe side effects, risk of mild side effects, protection duration, and absorption time. A heteroscedastic multinomial logit model was used, taking scale and preference heterogeneity (based on 19 patient characteristics) into account. Vaccination and patient characteristics both contributed to explain influenza vaccination uptake. Assuming a base case respondent and a realistic vaccination scenario, the predicted uptake was 58%. One-way changes in vaccination characteristics and patient characteristics changed this uptake from 46% up to 61% and from 37% up to 95%, respectively. The strongest impact on vaccination uptake was whether the patient had been vaccinated last year, whether s/he had experienced vaccination side effects, and the patient's general attitude towards vaccination. Although vaccination characteristics proved to influence influenza vaccination uptake, certain patient characteristics had an even higher impact on influenza vaccination uptake. Policy makers and general practitioners can use these insights to improve their communication plans and information regarding influenza vaccination for individuals aged 60 years or older. For instance, physicians should focus more on patients who had experienced side effects due to vaccination in the past, and policy makers should tailor the standard information folder to patients who had been vaccinated last year and to patient who had not.

2011-09-01

Pain management in craniotomy patients is challenging, with mild-to-moderate pain intensity, moderate-to-high risk of postoperative nausea and vomiting (PONV), and potentially catastrophic consequences of analgesic-related side-effects. The aim of this study was to determine whether i.v. parecoxib administered at dural closure during craniotomy decreased total morphine consumption and morphine-related side-effects compared with placebo. One hundred adult patients presenting for supratentorial craniotomy under propofol/remifentanil anaesthesia were randomized to receive parecoxib, 40 mg i.v., or placebo in a double-blind manner. All patients received local anaesthetic scalp infiltration, regular i.v. paracetamol, nurse-administered morphine in the post-anaesthesia care unit (PACU) until verbal analogue pain scores were ≤4/10 and patient-controlled morphine thereafter. Morphine consumption, pain intensity, and analgesia-related side-effects were recorded during the first 24 h after operation. Ninety-six patients (49 control and 47 parecoxib) were included in the analyses. Fifty-nine (61%) patients received morphine in the PACU and only one patient (control) did not receive any morphine in the postoperative period. There were no significant differences between the two groups in morphine consumption [20 (range: 0-102) vs 16 (range: 1-92) mg; P=0.38], pain intensity [excellent/very good pain relief in 78% of parecoxib patients; 74% of control patients (P=0.72)] or analgesia-related side-effects (PONV in 51% of parecoxib patients; 56% of control patients; P=0.55) in the first 24 h after operation. No major morbidity was recorded. Our study demonstrated no clinical benefit to adding i.v. parecoxib to local anaesthetic scalp infiltration, i.v. paracetamol, and patient-controlled i.v. morphine after supratentorial craniotomy.

Nerve transfer to relieve pain in upper brachial plexus injuries: Does it work?

Patients with C5 and C6 nerve root avulsion may complain from pain. For these patients, end-to-side nerve transfer of the superficial radial nerve into the median nerve is suggested to relieve pain. Eleven patients (with a primary brachial plexus reconstruction) undergoing end-to-side nerve transfer of the superficial radial nerve into the ulnovolar part of the median nerve were assessed. Pain before surgery was compared to that at 6-month follow-up using visual analog scale (VAS) scores. A significant difference was seen between the mean VAS before (8.5) and after surgery (0.7) (P=0.0). After the six-month follow-up, 6 patients felt no pain according to VAS, notwithstanding 5 patients with a mild pain. The evidence from the present study suggests that end-to-side nerve transfer of the superficial radial nerve into the ulnovolar part of the median nerve is an effective technique in reducing pain in patients with C5 and C6 nerve root avulsion.

The aim of this paper was to evaluate efficacy and tolerability of a topical gel (ACNAID TM gel medical device) containing 3% hydrogen peroxide (HPO), 1.5% salicylic acid (SA) and 4% D-panthenol (D-p) in the treatment of mild-moderate acne, comparing it with a previous formulation (ACNAID TM gel Cosmetic) containing 4% HPO, 0.5% SA, 4% D-p. Twenty patients of both sex with mild-moderate acne have been selected. The topical gel was applied twice a day for 60 days. Evaluations included: Global Acne Grading System (GAGS); lesions count; photographic assessment; a questionnaire to assess the tolerability. The results have been compared with those obtained in a previous study conducted with the formulation containing 4% HPO, 0.5% SA, 4% D-p. The GAGS score showed a reduction of 43% from T0 to T1 and of 61% from T0 to T2. Count of lesions: comedones reduction of 62% from T0 to T1 and of 95% from T0 to T2; papules reduction of 49% from T0 to T1 and of 68% from T0 to T2; pustules reduction of 75% from T0 to T1 and of 100% from T0 to T2. Digital images showed a significant reduction of acne lesions. At T2 the tolerability of the topical product was excellent according to 83% of patients and good according to 17% of patients. The topical gel has demonstrated to be effective and safe for treatment of mild to moderate acne. No patients reported side effects. These results are superior to those obtained in the previous study.

Pharmacological therapy with inhaled steroids (IS) is currently considered the gold-standard of treatment for mild-persistent asthma. Leukotriene receptor antagonist drugs (LTRAs) play an important role associated with IS, allowing dose tapering and maintaining control of asthma symptoms. The aim of this study was to determine the effectiveness of montelukast (MON) to allow tapering of the inhaled dose of budesonide (BUD) in patients with mild-moderate persistent asthma. This 16-wk single-blind randomized study included 40 asthmatic patients divided in 2 treatment groups. After a run-in period (4 wk), in which all patients inhaled 400 microg of BUD twice daily (bid), group A (20 patients) received MON (oral, 10 mg/day) combined with inhaled BUD (400 microg/bid), while group B (20 patients) was treated with BUD for the whole period of the study. In both groups, at every 4 wk the dose of BUD was halved. After 12 wk of treatment the mean value of forced expiratory volume during the first sec (FEV1, as % of predicted value) was significantly greater in group A compared with group B (94 +/- 7.5 vs 83.1 +/- 6.9; p<0.005). The mean values of peak expiratory flow (PEF), the percentages of asthmatic exacerbations, and the use of beta2-short-acting agonist (SABA) were similar in the 2 groups at 4, 8, and 12 wk. In conclusion, in patients with mild-moderate persistent asthma, MON therapy is useful in tapering the dose of IS in order to reduce its side effects and to maintain the clinical stability of the disease.

Transcutaneous intense focused ultrasound is a novel Food and Drug Administration-approved technology for noninvasive skin tightening of the face and neck. No studies have reported on its safety and effectiveness on nonfacial areas. Eighteen paired areas (6 each) on the upper arms, medial thighs, and extensor knees were randomly treated with two different transducers (4.0 MHz, 4.5-mm focal depth and 7.0 MHz, 3.0-mm focal depth). One side was randomly assigned to receive a single pass (single plane) of microthermal coagulation zones over the involved area with the 4.0 MHz, 4.5-mm-depth transducer, and the contralateral side was assigned to receive consecutive single passes (dual plane) using both transducers (4.0 MHz, 4.5-mm depth followed by 7.0 MHz, 3.0-mm depth). Two independent masked assessors determined clinical improvement scores using comparative standardized photographs obtained at baseline and 3 and 6 months after treatment. Subjective assessments of clinical improvement and side effects of treatment were obtained. Global assessment scores revealed significant improvement in all treated areas, with the upper arms and knees demonstrating more skin lifting and tightening than the thighs. Areas receiving dual-plane treatment had slightly better clinical scores than those receiving single-plane treatment in all three sites. Clinical scores from single-plane and dual-plane treated areas continued to improve between 3 and 6 months after treatment. Side effects were mild and transient and included erythema, warmth, and skin tenderness. Rare focal bruising was noted in two patients on the upper arms that resolved within 7 days. No other side effects were reported or observed. Transcutaneous intense focused ultrasound can be safely and effectively used to improve the clinical appearance (texture and contour) of the upper arms, extensor knees, and medial thighs. © 2012 by the American Society for Dermatologic Surgery, Inc.

The objective of this study was to compare conventional and conformal techniques of external beam radiotherapy (EBRT) in terms of the dose distribution, tumor response, and side effects in the treatment of locally advanced cervical cancer patients. A retrospective cohort study was conducted on cervical cancer patients who underwent EBRT before brachytherapy in the Radiotherapy Department of Cipto Mangunkusumo Hospital. The prescribed dose distribution, tumor response, and acute side effects of EBRT using conventional and conformal techniques were investigated. In total, 51 patients who underwent EBRT using conventional techniques (25 cases using Cobalt-60 and 26 cases using a linear accelerator (LINAC)) and 29 patients who underwent EBRT using conformal techniques were included in the study. The distribution of the prescribed dose in the target had an impact on the patient’s final response to EBRT. The complete response rate of patients to conformal techniques was significantly greater (58%) than that of patients to conventional techniques (42%). No severe acute local side effects were seen in any of the patients (Radiation Therapy Oncology Group (RTOG) grades 3-4). The distribution of the dose and volume to the gastrointestinal tract affected the proportion of mild acute side effects (RTOG grades 1-2). The urinary bladder was significantly greater using conventional techniques (Cobalt-60/LINAC) than using conformal techniques at 72% and 78% compared to 28% and 22%, respectively. The use of conformal techniques in pelvic radiation therapy is suggested in radiotherapy centers with CT simulators and 3D Radiotherapy Treatment Planning Systems (RTPSs) to decrease some uncertainties in radiotherapy planning. The use of AP/PA pelvic radiation techniques with Cobalt-60 should be limited in body thicknesses equal to or less than 18 cm. When using conformal techniques, delineation should be applied in the small bowel, as it is considered a critical organ according to RTOG consensus guidelines.

A field study was conducted to estimate the amount of Cr, Mn, and Ni deposited in the respiratory system of 44 welders in two facilities. Each worker wore a nanoparticle respiratory deposition (NRD) sampler during gas metal arc welding (GMAW) of mild and stainless steel and flux-cored arc welding (FCAW) of mild steel. Several welders also wore side-by-side NRD samplers and closed-face filter cassettes for total particulate samples. The NRD sampler estimates the aerosol's nano-fraction deposited in the respiratory system. Mn concentrations for both welding processes ranged 2.8-199 μg/m3; Ni concentrations ranged 10-51 μg/m3; and Cr concentrations ranged 40-105 μg/m3. Cr(VI) concentrations ranged between 0.5-1.3 μg/m3. For the FCAW process the largest concentrations were reported for welders working in pairs. As a consequence this often resulted in workers being exposed to their own welding fumes and to those generated from the welding partner. Overall no correlation was found between air velocity and exposure (R2 = 0.002). The estimated percentage of the nano-fraction of Mn deposited in a mild-steel-welder's respiratory system ranged between 10 and 56%. For stainless steel welding, the NRD samplers collected 59% of the total Mn, 90% of the total Cr, and 64% of the total Ni. These results indicate that most of the Cr and more than half of the Ni and Mn in the fumes were in the fraction smaller than 300 nm.

To investigate the efficacy and safety of Ji-Tai tablet and Ji-Tai tablet combined with buprenorphine in the treatment of patients with acute withdrawal syndrome of mild heroin dependence. A total of 150 patients with mild heroin dependence were recruited, and were randomly assigned to a Ji-Tai tablet group (n=50), a Ji-Tai tablet combined with buprenorphine group (n=50) and a control group (n=50) during a 10-day clinical trial. Opiate withdrawal scale (OWS) was used to measure the severity of withdrawal symptoms. Anxiety symptoms assessments were made at 0 day (baseline), the day 5 (middle), and the day 10 (end) by the Hamilton anxiety scale (HAMA). Symptoms were assessed before and 1 h or 2 h after medication each day. The total withdrawal symptoms scores and the daily reduction rate were used to measure the effect of Ji-Tai tablet vs Ji- Tai tablet plus buprenorphine. Safety evaluation was carried out by the following measures: baseline of treatment, drug side effects after the treatment, vital signs (blood pressure, heart rate, and respiration rate), laboratory examination (routine blood and urine tests and the liver and kidney function tests), and electrocardiograms. A total of 142 mild heroin dependence patients performed the experiments (including 48 in the Ji-Tai tablet group, 48 in the Ji-Tai tablet with buprenorphine group and 46 in the control group). The scores of baseline withdrawal symptoms were 43.520±19.786, 42.640±17.648 and 47.100±24.450, respectively, with no significant differences among the 3 groups (all P>0.05 ). During the 10-day treatment, the reduction rate of acute withdrawal symptoms scores increased daily, the acute withdrawal syndrome scores and the anxiety symptoms scores declined from day 0 to day 10, there was also no significant difference among the 3 groups (all P>0.05). Ji-Tai tablet did not affect vital signs such as blood pressure, heart rate, and respiration rate. Ji-Tai tablet or Ji-Tai tablet combined with buprenorphine had no effect on acute withdrawal symptoms of mild heroin dependence.

Glucocorticoid (GC) therapy has been shown to prevent Graves' ophthalmopathy (GO) progression following radioactive iodine (RAI) treatment. However, the optimal regimen is controversial, with studies from recent years suggesting the use of lower doses and shorter GC treatment courses. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and retrospective controlled trials comparing GC regimens versus placebo, no treatment, or other GC regimens. Eight trials evaluating 850 patients fulfilled inclusion criteria. In patients with preexisting GO, standard dose prednisone (0.4-0.5 mg/kg tapered over 3 months) was very effective for prevention of GO progression (OR 0.14 [CI 0.06-0.35], p<0.01) in patients with mild to moderate GO. Two studies evaluated low-dose prednisone (0.2-0.3 mg/kg for 4-6 weeks) in patients with mild GO or risk factors, but were limited by not including patients with preexisting GO in the control groups. Therefore, the two low-dose groups were evaluated using indirect comparisons with control groups matched for age and clinical activity score, showing excellent efficacy versus no treatment or placebo (OR 0.20 [CI 0.07-0.60], p=0.004) and no significant difference compared with standard dose (OR 1.7 [CI 0.52-5.52], p=0.47). In patients without preexisting GO, steroid prophylaxis had no beneficial effect (OR 1.87 [CI 0.81-4.3]), though there were insufficient data regarding patients with risk factors for GO development. GC prophylaxis had no impact on hyperthyroidism resolution (OR 1.05 [CI 0.69-1.58]), and GC side effects were common but mild. Current evidence supports a three-tier approach for prevention of GO progression following RAI. Standard dose prednisone is the best validated regimen and should be used in patients with mild to moderate GO who have high risk of progression, while low dose prednisone can be used in patients with mild GO, and in patients without preexisting GO who have risk factors and are selected for GC prophylaxis. Patients without preexisting GO and without risk factors should not be treated with GC prophylaxis.

[Noninvasive alternatives to CPAP in therapy of obstructive sleep apnea syndrome].

2000-07-01

Non-surgical treatment of the sleep apnea syndrome comprises behavioral modification such as sleep hygiene, weight reduction, and positional training as an adjunct to standard therapy with continuous positive airway pressure (CPAP) applied via a nasal mask. For patients who cannot tolerate or are not willing to use CPAP for psychological or other reasons, removable intraoral appliances that advance the mandible during sleep are a valuable treatment alternative. Randomised controlled trials have confirmed effectiveness of intraoral appliances in relieving symptoms and measured sleep and respiratory disturbances. Side effects including hypersalivation, mucosal dryness, tooth and temporo-mandibular joint discomfort are common but usually mild. To timely detect effects of oral appliances on occlusion and on the temporo-mandibular joint longterm orthodontic monitoring is advisable.

Background and Aims Pectin is a complex macromolecule, the fine structure of which is influenced by many factors. It is used as a gelling, thickening and emulsifying agent in a wide range of applications, from food to pharmaceutical products. Current industrial pectin extraction processes are based on fruit peel, a waste product from the juicing industry, in which thousands of tons of citrus are processed worldwide every year. This study examines how pectin components vary in relation to the plant source (orange, lemon, lime, grapefruit) and considers the influence of extraction conditions on the chemical and macromolecular characteristics of pectin samples. Methods Citrus peel (orange, lemon, lime and grapefruit) from a commercial supplier was used as raw material. Pectin samples were obtained on a bulk plant scale (kilograms; harsh nitric acid, mild nitric acid and harsh oxalic acid extraction) and on a laboratory scale (grams; mild oxalic acid extraction). Pectin composition (acidic and neutral sugars) and physicochemical properties (molar mass and intrinsic viscosity) were determined. Key Results Oxalic acid extraction allowed the recovery of pectin samples of high molecular weight. Mild oxalic acid-extracted pectins were rich in long homogalacturonan stretches and contained rhamnogalacturonan I stretches with conserved side chains. Nitric acid-extracted pectins exhibited lower molecular weights and contained rhamnogalacturonan I stretches encompassing few and/or short side chains. Grapefruit pectin was found to have short side chains compared with orange, lime and lemon. Orange and grapefruit pectin samples were both particularly rich in rhamnogalacturonan I backbones. Conclusions Structural, and hence macromolecular, variations within the different citrus pectin samples were mainly related to their rhamnogalacturonan I contents and integrity, and, to a lesser extent, to the length of their homogalacturonan domains.

Dysfunction of neuroplasticity due to N-methyl-d-aspartate (NMDA) receptor hypofunction may be a causal factor for memory and executive dysfunctioning in schizophrenia. Deregulation of NMDA transmission in the prefrontal cortex may also explain negative and positive symptoms. Clozapine augmentation with memantine targets altered NMDA receptor-mediated neurotransmission in schizophrenia and showed substantial beneficial effects on several symptom domains in a small proof-of-concept study. We evaluate effects of memantine add-on treatment to clozapine for memory and executive function, and negative and positive symptoms in schizophrenia. Clozapine-treated patients with refractory schizophrenia were randomly assigned to 12 weeks of double-blind adjunctive treatment with memantine (n = 26) or placebo (n = 26). Crossover occurred after a 2-week placebo wash-out period. Primary endpoints were change from baseline to 12 weeks treatment and 14 weeks to 26 weeks treatment on memory and executive function using the Cambridge Neuropsychological Test Automated Battery (CANTAB), Positive and Negative Syndrome Scale (PANSS), and Clinical Global Impression Severity Scale (CGI-S). Side effects were assessed using the Liverpool University Neuroleptic Side-Effect Rating Scale. When compared with placebo, memantine improved a composite memory score comprising verbal recognition memory and paired associates learning task scores on the CANTAB (effect size = 0.30) and PANSS negative subscale score (effect size = 0.29). Side effects were mild and transient. In patients with clozapine-treated refractory schizophrenia, memantine addition significantly improved verbal and visual memory and negative symptoms without serious adverse effects. These results justify further investigations on long-term memantine augmentation to clozapine in treatment-resistant schizophrenia.

In a clinical trial of moxifloxacin in eight multibacillary leprosy patients, moxifloxacin proved highly effective. In all trial patients, a single 400-mg dose of moxifloxacin resulted in significant killing (P ≤ 0.006) of Mycobacterium leprae, ranging from 82% to 99%, with a mean of 91%. In all instances, no viable bacilli were detected with an additional 3 weeks of daily therapy, this observed rapid bactericidal activity being matched previously only by rifampin. On moxifloxacin therapy, skin lesions cleared exceedingly rapidly with definite improvement observed consistently after eight doses and progressive resolution continuing for the 56 days of the trial. Side effects, toxicities, and laboratory abnormalities were mild, not requiring discontinuation of therapy. PMID:18573938

Hyperkalemia affects up to 10% of patients with CKD. Sodium polystyrene sulfonate has long been prescribed for this condition, although evidence is lacking on its efficacy for the treatment of mild hyperkalemia over several days. This study aimed to evaluate the efficacy of sodium polystyrene sulfonate in the treatment of mild hyperkalemia. In total, 33 outpatients with CKD and mild hyperkalemia (5.0-5.9 mEq/L) in a single teaching hospital were included in this double-blind randomized clinical trial. We randomly assigned these patients to receive either placebo or sodium polystyrene sulfonate of 30 g orally one time per day for 7 days. The primary outcome was the comparison between study groups of the mean difference of serum potassium levels between the day after the last dose of treatment and baseline. The mean duration of treatment was 6.9 days. Sodium polystyrene sulfonate was superior to placebo in the reduction of serum potassium levels (mean difference between groups, -1.04 mEq/L; 95% confidence interval, -1.37 to -0.71). A higher proportion of patients in the sodium polystyrene sulfonate group attained normokalemia at the end of their treatment compared with those in the placebo group, but the difference did not reach statistical significance (73% versus 38%; P=0.07). There was a trend toward higher rates of electrolytic disturbances and an increase in gastrointestinal side effects in the group receiving sodium polystyrene sulfonate. Sodium polystyrene sulfonate was superior to placebo in reducing serum potassium over 7 days in patients with mild hyperkalemia and CKD. Copyright © 2015 by the American Society of Nephrology.

Evaluation of Craft S, Baker LD, Montine TJ, Minoshima S, Watson GS, Claxton A, et al. Intranasal Insulin Therapy for Alzheimer Disease and Amnestic Mild Cognitive Impairment: A Pilot Clinical Trial. Arch Neurol . 2011 Sep 12. Alzheimer's disease is associated with brain insulin deficiency and insulin resistance, similar to the problems in diabetes. If insulin could be supplied to the brain in the early stages of Alzheimer's, subsequent neurodegeneration might be prevented. Administering systemic insulin to elderly non-diabetics poses unacceptable risks of inadvertant hypoglycemia. However, intranasal delivery directs the insulin into the brain, avoiding systemic side-effects. This pilot study demonstrates both efficacy and safety of using intranasal insulin to treat early Alzheimer's and mild cognitive impairment, i.e. the precursor to Alzheimer's. Significant improvements in learning, memory, and cognition occured within a few months, but without intranasal insulin, brain function continued to deteriorate in measurable degrees. Intranasal insulin therapy holds promise for halting progression of Alzheimer's disease.

Carbon dioxide (CO2) laser treatment is a common therapeutic modality for many dermatologic conditions. It uses a high energy, infrared beam of light, which selectively targets water-containing tissue resulting in controlled ablative resurfacing. This modality, however, can manifest significant cosmetic side effects. Here we report a case of verruca plana manifesting as a response to CO2 laser treatment. A 74-year-old female with recent Mohs surgery for a basal cell carcinoma, presented for full-face-fractionated CO2 treatment to address her surgical scars in addition to treating her mild diffuse actinic damage. Six weeks post treatment, the patient developed erythematous thin plaques over the areas that had been treated. Histology was consistent with verruca plana. Lesions showed mild improvement with topical tretinoin. Verruca plana are benign and typically self-limited; however, they can present a significant cosmetic burden to patients and are an important complication to consider when performing elective cosmetic procedures.

This analysis was conducted to evaluate the efficacy and safety of icotinib based regimens in treating patients with non-small cell lung cancer (NSCLC). Clinical studies evaluating the efficacy and safety of icotinib-based regimens with regard to response and safety for patients with NSCLC were identified using a predefined search strategy. Pooled response rates of treatment were calculated. With icotinib-based regimens, 7 clinical studies which including 5,985 Chinese patients with NSCLC were considered eligible for inclusion. The pooled analysis suggested that, in all patients, the positive reponse rate was 30.1% (1,803/5,985) with icotinib-based regimens. Mild skin itching, rashes and diarrhea were the main side effects. No grade III or IV renal or liver toxicity was observed. No treatment-related death occurred in patients treated with icotinib-based regimens. This evidence based analysis suggests that icotinib based regimens are associated with mild response rate and acceptable toxicity for treating Chinese patients with NSCLC.

For cancer chemotherapy, a tumor regression without any surgical resection and severe side effects is greatly preferred to merely slowing down the growth of tumors. Here, we report a formulation composed of irinotecan (IRN) and poly(D,L-lactide-co-glycolide)-b-poly(ethylene glycol)-b-poly(D,L-lactide-co-glycolide) (PLGA-PEG-PLGA). IRN is a clinically used antitumor drug with active and inactive chemical forms in equilibrium, and the major form at physiological conditions is inactive but still has side effects. The aqueous solution of the PLGA-PEG-PLGA is a sol at room temperature and physically gels at body temperature, forming a thermogel. We successfully mixed this moderately soluble drug into the amphiphilic copolymer aqueous solution for the first time. The mixture was subcutaneously injected into nude mice with xenografted SW620 human colon tumors. Excellent in vivo antitumor efficacy was observed in the group that received the IRN-loaded thermogel. The tumor was significantly regressed after being treated with the IRN/thermogel, and the side effects (blood toxicity and body weight decrease) were very mild. These results might be attributed to the ideal sustained release profile and period of release of the drug from the thermogel and to the significant enhancement of the fraction of the active form of the drug by the thermogel.

To investigate the side effects of 600 microg oral misoprostol given for the mother and the newborn to prevent postpartum hemorrhage (PPH). One thousand six hundred twenty women delivering at home or subcentres in rural India were randomised to receive misoprostol or placebo in the third stage of labour. Women were evaluated for shivering, fever, nausea, vomiting and diarrhea at 2 and 24 h postpartum. Newborns were evaluated within 24 h for diarrhea, vomiting and fever. Symptoms were graded as absent, mild-to-moderate or severe. Women who received misoprostol had a significantly greater incidence of shivering (52%vs. 17%, p < 0.001) and fever (4.2%vs. 1.1%, p < 0.001) at 2 h postpartum compared with women who received placebo. At 24 h, women in the misoprostol group experienced significantly more shivering (4.6%vs. 1.4%, p < 0.001) and fever (1.4%vs. 0.4%, p < 0.03). There were no differences in nausea, vomiting or diarrhea between the two groups. There were no differences in the incidence of vomiting, diarrhea or fever for newborns. Misoprostol is associated with a significant increase in postpartum maternal shivering and fever with no side effects for the newborn. Given its proven efficacy for the prevention of PPH, the benefits of misoprostol are greater than the associated risks.

Background Global population aging will result in increasing rates of cognitive decline and dementia. Thus, effective, low-cost, and low side-effect interventions for the treatment and prevention of cognitive decline are urgently needed. Our study is the first to investigate the effects of Kundalini yoga (KY) training on mild cognitive impairment (MCI). Methods Older participants (≥55 years of age) with MCI were randomized to either a 12-week KY intervention or memory enhancement training (MET; gold-standard, active control). Cognitive (i.e. memory and executive functioning) and mood (i.e. depression, apathy, and resilience) assessments were administered at baseline, 12 weeks and 24 weeks. Results At baseline, 81 participants had no significant baseline group differences in clinical or demographic characteristics. At 12 weeks and 24 weeks, both KY and MET groups showed significant improvement in memory; however, only KY showed significant improvement in executive functioning. Only the KY group showed significant improvement in depressive symptoms and resilience at week 12. Conclusion KY group showed short- and long-term improvements in executive functioning as compared to MET, and broader effects on depressed mood and resilience. This observation should be confirmed in future clinical trials of yoga intervention for treatment and prevention of cognitive decline (NCT01983930). PMID:28088925

Although the effectiveness of low-dose radiotherapy for chronic degenerative and inflammatory diseases has been documented in previous studies, patient-reported clinical outcomes are rarely available. This study aimed to determine the effect of low-dose radiotherapy on patients with painful plantar fasciitis. From 2002 to 2008, 200 patients older than 65 years of age with painful plantar fasciitis were treated in our hospital. Records from 171 of these patients were available for analysis. All patients were treated with an identical dose of 3Gy using identical equipment and techniques. Response was evaluated with patient-reported questionnaires and clinical visits. Minimum-term follow-up was 18 months, with mean follow-up at 54 months. Three months after receiving low-dose radiotherapy, 67.3% of patients had no or mild pain, and 57.9% had no or discrete mobility restriction. At a mean of 54 months, 61.4% of patients had no or mild pain and 64.9% of patients had no or discrete mobility restriction; 60.8% of patients reported improved quality of life. Low-dose radiotherapy is effective in most patients with painful plantar fasciitis. Due to minimal side effects and low costs, it represents an excellent treatment option compared to conventional therapies or surgery. Copyright © 2014 Elsevier Ltd. All rights reserved.

Power toothbrushes (PTBs), in combination with abrasive dentifrices, may encourage wear of dental cements at crown margins. The objective of this in vitro simulation was to control the clinical variables associated with PTB use and measure the potential side effects of PTBs with mild and abrasive dentifrices. Four PTBs ( Braun-Oral-B-Professional Care at 150 g brushing force, Sonicare-Elite at 90 g, Colgate-Actibrush at 200 g and Crest-Spinbrush-Pro at 250 g) and 2 dentifrices mixed 1:1 with tap water (Mild= Colgate-Total, Colgate-Palmolive; Abrasive= Close-up, Chesebrough-Ponds) versus tap water alone (control) were used to abrade 2 cements (Fleck's Mizzy Zinc Phosphate [ZP]; 3M-ESPE Unicem universal cement [UC]) using cement-filled slots (160 m wide) cut into wear-resistant ceramic blocks. A custom fixture controlled PTB/block alignment, PTB loads, and other testing variables. Wear was measured (3 profilometer traces/slot, 5 slots/block/group, baseline to 5-year differences) and analyzed (3-way ANOVA, p < or = 0.05, Bonferroni). Wear for ZP was much greater than UC (p<0.05) for all 4 PTBs and both dentifrices. Brushing with water showed no effects (p<0.05). Cement-PTB-dentifrice interactions did occur. Only minor differences occurred among PTBs. Pooled 5y-wear levels for ZP for both dentifrices approximately 21 microm /5y) were similar to values for current-day posterior composite materials. Combinations of PTBs with mild and abrasive dentifrices produced significant wear with ZP but not UC; thus, resin-composite cements seem to represent a better choice for wear resistance.

Clindamycin phosphate (CDP), benzoyl peroxide (BPO) and salicylic acid (SA) are known to be effective acne therapy agents depending on their anti-inflammatory and comedolytic properties. The purpose of this study was to investigate the efficacy and tolerability of the addition of SA treatment to CDP and BPO (SA and CDP + BPO) and compare it with CDP + BPO in patients with mild to moderate facial acne vulgaris. Forty-nine patients were enrolled in a 12 week prospective, single-blind, randomized, comparative clinical study. Efficacy was assessed by lesion counts, global improvement, quality of life index and measurements of skin barrier functions. Local side effects were also evaluated. Both combinations were effective in reducing total lesion (TL), inflammatory lesion (IL) and non-inflammatory lesion (NIL) counts. There were statistically significant differences between treatment groups for reductions in NIL counts beyond 2 weeks, IL counts and TL counts throughout the all study weeks, and global improvement scores evaluated by patients and investigator at the end of the study in favor of SA and CDP + BPO treatment when compared to CDP + BPO treatment. Both combinations significantly decreased stratum corneum hydration, although skin sebum values decreased with SA and CDP + BPO treatment. These combinations were also well tolerated except significantly higher frequency of mild to moderate transient dryness in patients applied SA and CDP + BPO. The addition of SA to CDP + BPO treatment demonstrated significantly better and faster results in terms of reductions in acne lesion counts and well tolerated except for higher frequency of mild to moderate transient dryness. © 2011 Japanese Dermatological Association.

This retrospective case series was designed to compare the long-term safety and efficacy of bipolar fractional radiofrequency (FRF) therapy as a treatment for atrophic acne scars (ASs) and acne vulgaris. Few clinical and histological studies have examined the long-term utility of bipolar FRF therapy as a treatment for ASs and acne in people with darker skin. Eight Japanese patients with ASs and mild-to-severe acne on both cheeks were treated with a bipolar FRF system (eMatrix; Syneron). Five treatment sessions with the same settings (coverage rate: 10%; peak energy: 62 mJ/pin; two passes) were carried out at 1-month intervals, and the patients were followed up for at least 1 year after the final treatment. Assessments of ASs and acne severity were performed and samples were removed for histological examination. We demonstrated that mild ASs responded better than moderate and severe ASs, and at least 50% improvement in scar severity was seen in 50% of patients after the final treatment. Six patients remained disease free at 1.5 years without the use of any additional therapies. The biopsy specimens showed a marked improvement characterized by a decrease in dermal pilosebaceous units and perivascular inflammatory cell infiltrates with an increase in elastin content and collagen deposition in the upper dermis. Bipolar FRF treatment showed long-term effectiveness against mild ASs and acne in Asian patients and had minimal side effects.

To study the efficacy and tolerability of agomelatine (valdoxan) in treatment of mild depressive states in patients with chronic brain ischemia (CBI). The study comprised 33 patients (23 women, 10 men, average age 54.5 years), including 12 people (36.4%) with CBI, stage I, and 21 (63.6%) with CBI, stage II. All patients had a single depressive episode of mild severity. Diagnosis of affective and cognitive impairment was carried out using clinical and neuropsychological methods (the Hamilton Depression Rating Scale (HDRS-17), the Hospital Anxiety and Depression Scale (HADS), the night sleep questionnaire developed by A.M. Vein, the Mini-mental state examination (MMSE), the modified Mini-Cog method, the Montreal Cognitive Assessment Scale (MoCA), the Clinical Global Impression scale (CGI-S, CGI-I) to assess the degree and dynamics of the disease, the Patient Global Impression (PGI) scale. The survey had been performed after 2,4 and 8 weeks of treatment. Agomelatine (valdoxan) was used 1 time per day in the evening in a dose of 25 mg (1 tablet). Agomelatine improved sleep from the second week of treatment, reduced anxiety symptoms after six weeks and depressive symptoms after eight weeks. The improvement of cognitive functions was noted as well. No side-effects was observed. The results revealed the high antidepressive activity of the drug in treatment of mild depressive states in patients with chronic brain ischemia, the balanced spectrum of effects on anxiety, depression, insomnia, the positive effect on cognitive functions that allows to recommend agomelatine in treatment of patients with CBI.

Executive function is independently associated with performances of balance and mobility in community-dwelling older adults after mild stroke: implications for falls prevention

2015-01-01

Background Stroke survivors have a high incidence of falls. Impaired executive-controlled processes are frequent in stroke survivors and are associated with falls in this population. Better understanding of the independent association between executive-controlled processes and physiological fall risk (i.e. performances of balance and mobility) could enhance future interventions that aim to prevent falls and to promote an independent lifestyle among stroke survivors. Methods Cross-sectional analysis of 63 adults who suffered a mild stroke >1 year prior to the study, aged > or =50 years. Results Cognitive flexibility was independently associated with performances of balance and mobility in community-dwelling older adults after mild stroke, after accounting for age, quadriceps strength of the paretic side and current physical activity level. Conclusions Clinicians may need to consider cognitive function when assessing and treating impaired balance and mobility in community-dwelling older adults after mild stroke. PMID:17143004

Safety of available and emerging drug therapies for hyperhidrosis.

Hosp, Christine; Hamm, Henning

Hyperhidrosis affects 4.8% of the U.S. population and has been underestimated by physicians for long time despite considerable interference with quality of life. Many patients suffer from primary (idiopathic) hyperhidrosis which results from over-activity of sympathetic nerves and is restricted to specific body areas, mostly the axillae, palms, soles, or head. Secondary hyperhidrosis is caused by an underlying disease or the intake of medications and often involves large parts of the body. Numerous effective therapies with topical or systemic drugs and surgical options are available. Areas covered: Efficacy and safety data on aluminum salts, anticholinergic drugs for topical or systemic application, and on intradermal botulinum toxin injections used to treat hyperhidrosis are critically evaluated, including data from clinical trials with focus on possible side effects and long-term complications in dispute. Expert opinion: Hyperhidrosis often responds well to available therapies. Depending on the type of hyperhidrosis treatment should be topical/local or systemic. Most of the side effects are mild, transient and easily manageable. In case of systemic treatment with anticholinergics low dosing and up-titration of medication is necessary to avoid severe adverse effects. Concerns about the promotion of breast cancer and Alzheimer disease by topical aluminum salts are unsolved.

To assess the prevalence of gastrointestinal toxicity in dogs receiving chemotherapy with vincristine and cyclophosphamide and the efficacy of maropitant citrate (Cerenia™, Zoetis) in reducing these events. Dogs receiving chemotherapy with cyclophosphamide or vincristine were randomised to either receive maropitant or not in the period immediately after treatment and for 4 days afterwards. Owners completed a diary of adverse events following treatment. Adverse events occurred in 40/58 (69%) dogs in the vincristine group. Most of these adverse events were mild and included: lethargy (62%), appetite loss (43%), diarrhoea (34%) and vomiting (24%). Adverse events occurred in 34/42 (81%) dogs treated with cyclophosphamide. Most of these adverse events were mild and included: lethargy (62%), diarrhoea (36%), appetite loss (36%) and vomiting (21%). There was no difference in total clinical score, vomiting, diarrhoea, appetite loss or lethargy score between dogs treated with maropitant and non-treated dogs in either the vincristine or cyclophosphamide groups. Chemotherapy-related side effects are frequent but usually mild in dogs receiving vincristine or cyclophosphamide. Prophylactic administration of maropitant does not reduce the frequency of adverse events and maropitant should be administered only as required for individual cases. © 2014 British Small Animal Veterinary Association.

Purpose Vemurafenib is a potent inhibitor of V600 mutant BRAF with significant impact on progression-free and overall survival in advanced melanoma. Cutaneous side effects are frequent. This single-center observational study investigates clinical and histological features of these class-specific cutaneous adverse reactions. Patients and Methods Patients were all treated with Vemurafenib 960 mg b.i.d. within local ethic committees approved clinical trials. All skin reactions were collected and documented prospectively. Cutaneous reactions were classified by reaction pattern as phototoxic and inflammatory, hair and nail changes, keratinocytic proliferations and melanocytic disorders. Results Vemurafenib was well tolerated, only in two patients the dose had to be reduced to 720 mg due to arthralgia. 26/28 patients (93%) experienced cutaneous side effects. Observed side effects included UVA dependent photosensitivity (n = 16), maculopapular exanthema (n = 14), pruritus (n = 8), folliculitis (n = 5), burning feet (n = 3), hair thinning (mild alopecia) (n = 8), curly hair (n = 2) and nail changes (n = 2). Keratosis pilaris and acanthopapilloma were common skin reactions (n = 12/n = 13), as well as plantar hyperkeratosis (n = 4), keratoacanthoma (n = 5) and invasive squamous cell carcinoma (n = 4). One patient developed a second primary melanoma after more than 4 months of therapy (BRAF and RAS wild type). Conclusion Vemurafenib has a broad and peculiar cutaneous side effect profile involving epidermis and adnexa overlapping with the cutaneous manifestations of genetic diseases characterized by activating germ line mutations of RAS (RASopathy). They must be distinguished from allergic drug reaction. Regular skin examination and management by experienced dermatologists as well as continuous prophylactic photo protection including an UVA optimized sun screen is mandatory. PMID:23516541

Oral oxybutynin for treating hyperhidrosis is effective and safe. Its side-effects are mild but frequent so we consider whether transdermal oxybutynin (considered to have a better side-effect profile) could be an alternative for treating hyperhidrosis. During 2015, a prospective study was conducted. Epidemiological variables, effectiveness (using the Hyperhidrosis Disease Severity Scale) and tolerance to transdermal oxybutynin were compiled concerning two different groups (patients previously treated or untreated with oral oxybutynin), at baseline, and at 3 and 12 months. Seven previously treated and six previously untreated patients were included. Five patients in the first group discontinued the treatment within 3 months. Of the two remaining patients, one reported ineffectiveness and the other obtained an excellent response but discontinued due to local irritation. Among the untreated patients, two showed no response and four experienced improvement (three with "partial response" and one with "excellent response"). All patients discontinued treatment within 12 months. No major adverse effects were observed. The absence of active metabolites after transdermal oxybutynin could result in less effectiveness than oral oxybutynin, although it is usually well tolerated. In conclusion, transdermal oxybutynin could have low effectiveness for the treatment of hyperhidrosis in patients following intolerance to oral oxybutynin but could provide good results in patients who have never tried systemic drugs. © 2017 Japanese Dermatological Association.

The use of herbal medicines including different types of tea is among the different strategies for preventing and controlling the side-effects of diabetes. The aim of the present study was to compare the effect of sour tea and green tea on mildly hypertensive patients with diabetes. The present study was a randomized clinical trial in which 100 mildly hypertensive patients with diabetes were randomly assigned into sour tea group (ST) and green tea group (GT). They were instructed to drink sour tea and green tea infusion, respectively, three times a day 2 hr after each meal for 4 weeks. The participants' blood pressure was measured at days 1, 15, and at the end of study. The systolic pressure of both groups statistically decreased at the end of the study; it decreased from 123.1 ± 15.5 to 116.8 ± 16.3 mmHg in the ST and from 119.4 ± 15.1 to 114.8 ± 15.9 mmHg in the GT. The diastolic pressure of both groups statistically decreased by the end of the study; it decreased from 79.4 ± 11.1 to 74.5 ± 9.3 mmHg in the ST and from 78.9 ± 8.3 to 75.3 ± 7.7 mmHg in the GT. The therapeutic effectiveness of tea drinking by the end of intervention was 43.5% in the ST and 39.6% in the GT compared to the beginning. The present study revealed that mildly hypertensive type 2 diabetic individuals who drink three glasses of green or sour tea daily for 4 weeks show significant decreased systolic and diastolic blood pressures.

Parkinson's disease (PD) is a progressive neurodegenerative disorder with motor and non-motor symptoms, including cognitive deficits. Several magnetic resonance imaging approaches have been applied to investigate brain atrophy in PD. The aim of this study was to detect early structural cortical and subcortical changes in de novo PD whilst distinguishing cognitive status, clinical phenotype and motor laterality. Eighteen de novo PD with mild cognitive impairment (PD-MCI), 18 de novo PD without MCI (PD-NC) and 18 healthy control subjects were evaluated. In the PD-MCI group, nine were tremor dominant and nine were postural instability gait disorder (PIGD) phenotype; 11 had right-sided symptom dominance and seven had left-sided symptom dominance. FreeSurfer was used to measure cortical thickness/folding, subcortical structures and to study group differences as well as the association with clinical and neuropsychological data. Parkinson's disease with MCI showed regional thinning in the right frontal, right middle temporal areas and left insula compared to PD-NC. A reduction of the volume of the left and right thalamus and left hippocampus was found in PD-MCI compared to PD-NC. PD-MCI PIGD showed regional thinning in the right inferior parietal area compared to healthy controls. A decreased volume of the left thalamus was reported in PD-MCI with right-sided symptom dominance compared to PD-NC and PD-MCI with left-sided symptom dominance. When MCI was present, PD patients showed a fronto-temporo-parietal pattern of cortical thinning. This cortical pattern does not appear to be influenced by motor laterality, although one-sided symptom dominance may contribute to volumetric reduction of specific subcortical structures. © 2015 EAN.

This study analyzed the effects of pseudoephedrine (PSE) provided at different time of day on neuromuscular performance, side effects, and violation of the current doping cut-off threshold [World Anti-Doping Agency (WADA)]. Nine resistance-trained males carried out bench press and full squat exercises against four incremental loads (25%, 50%, 75%, and 90% one repetition maximum [1RM]), in a randomized, double-blind, cross-over design. Participants ingested either 180 mg of PSE (supra-therapeutic dose) or placebo in the morning (7:00 h; AM(PLAC) and AM(PSE)) and in the afternoon (17:00 h; PM(PLAC) and PM(PSE)). PSE enhanced muscle contraction velocity against 25% and 50% 1RM loads, only when it was ingested in the mornings, and only in the full squat exercise (4.4-8.7%; P < 0.05). PSE ingestion raised urine and plasma PSE concentrations (P < 0.05) regardless of time of day; however, cathine only increased in the urine samples. PSE ingestion resulted in positive tests occurring in 11% of samples, and it rose some adverse side effects such us tachycardia and heart palpitations. Ingestion of a single dose of 180 mg of PSE results in enhanced lower body muscle contraction velocity against low and moderate loads only in the mornings. These mild performance improvements are accompanied by undesirable side effects and an 11% risk of surpassing the doping threshold. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Studies using a 755 nm picosecond laser with a focus lens array have been reported to be effective for facial wrinkles and pigmentation. This study reports the safety and efficacy using a shorter interval of 2-3 weeks between treatments. Nineteen female subjects and one male subject, primarily Fitzpatrick skin types II and III (one skin type I), who had mild to moderate wrinkles and sun-induced pigmentation were enrolled and treated using the 755 nm PicoSure Laser with focus lens array. The skin was cleansed then wiped with an alcohol wipe prior to treatment. Lidocaine 30% ointment and/or forced air cooling could be used to increase subject comfort. Adjacent pulses, with minimal overlap (10% or less), were delivered to the full face. Subjects received four treatments, performed at 2-3-week intervals. The laser energy used was 0.71 J/cm 2 . The physician administered 3-7 passes with an average total of 6,253 pulses per treatment. Follow-up visits occurred at 1 and 3 months post-last treatment at which the physician scored satisfaction and improvement and subjects scored satisfaction and likelihood to recommend to others. The most common side effects were mild swelling, pain, redness, and crusting, most of which subsided within hours of the treatment, with the latest resolving within 48 hours. This is similar to a previous reported study (Weiss et al. ASLMS 2015) where treatments were performed every 6 weeks with side effects resolving within 24 hours. At the 1 and 3 month follow-up visits, 94% (n = 19) and 93% (n = 15) of subjects scored themselves as satisfied or extremely satisfied with their overall results and 81% and 93% were likely to recommend the treatment based on global assessment, respectively. The treating physician was satisfied with 93% of subject's overall results. Three blinded evaluators were able to correctly identify the baseline from post-treatment photographs in 77% of the subjects at the 1 month follow-up and 69% of the subjects at the 3 month follow-up, on average. The average treatment pain score was 4.2 on a 1-10 scale. A compressed treatment interval expedites results without increasing side effects and resulted in a high physician and subject satisfaction rate. Lasers Surg.

Antibiotics/antimicrobials: systemic and local administration in the therapy of mild to moderately advanced periodontitis.

Jepsen, Karin; Jepsen, Søren

2016-06-01

This review gives an update of the current scientific evidence on the efficacy of the adjunctive use of systemic and local antibiotics/antimicrobials in the treatment of periodontitis. In particular, it addresses whether their use can improve the results of nonsurgical mechanical therapy in mild-to-moderate forms of the disease. Large numbers of randomized clinical trials and systematic reviews with meta-analyses have clearly established that adjunctive systemic antibiotics, combined with mechanical debridement, offer clinical improvements additional to those obtained with scaling and root planing alone. These effects are more pronounced in aggressive periodontitis and in initially deep pockets, whereas more limited additional improvements, of 0.3 mm for additional pocket reduction and 0.2 mm for additional clinical attachment gain, have been documented for moderately deep sites (4-6 mm) in patients with chronic periodontitis. The marginal clinical benefit in patients with moderate disease has to be balanced against possible side effects. Notably, it has to be realized that an increasing number of warnings have been articulated against the unrestricted use of antibiotics in treating periodontal diseases because of the emerging global public health issue of bacterial resistance. The effects of the adjunctive local administration of antimicrobials have also been very well documented in several systematic reviews. Overall, in persistent or recurrent localized deep sites, the application of antimicrobials by sustained-delivery devices may offer a benefit of an additional 0.4 mm in pocket depth reduction and 0.3 mm in clinical attachment level gain. In conclusion, the slight additional benefits of adjunctive antimicrobials, which were shown for moderate forms of periodontitis, have to be balanced against their side effects and therefore their prescription should be limited as much as possible. © 2016 John Wiley & Sons A/S.

Formulary review of therapeutic alternatives for atopic dermatitis: focus on pimecrolimus.

PubMed

Weinberg, Jeffrey M

2005-01-01

Atopic dermatitis (AD), often called eczema, is characterized by intense pruritus, erythema, dry skin, and inflammation. The condition is chronic and relapsing, and often occurs in patients with a family history of the atopic triad (asthma, allergic rhinitis, and AD). Use of topical steroids has been the mainstay of medical treatment for AD. Steroid-free treatments for AD, with a more favorable safety profile, have become available within the past 2 years. Tacrolimus ointment, a topical immunomodulator, became available in early 2001 and is indicated for moderate-to-severe AD. A similar but highly skinselective cytokine inhibitor, pimecrolimus cream 1%, became available in March 2002. Pimecrolimus is indicated for mild-to-moderate AD. The objective of this article is to review the key characteristics that differentiate pimecrolimus from steroids and tacrolimus in the treatment of AD. Using secondary resources, the clinical aspects and conventional treatment strategies for AD are reviewed as are the pivotal clinical studies with pimecrolimus and literature on quality of life and economic burden of disease for AD patients and families. Pimecrolimus is an effective, steroid-sparing therapy for mild-tomoderate AD. Early treatment prevents flares, the agent works quickly to reduce signs and symptoms of more advanced AD, and it is safe and appropriate for intermittent long-term therapy. Pimecrolimus has fewer side effects than topical steroids and a better side-effect profile than tacrolimus. It can also be used as a first-line therapy. In studies with patients aged 2 to 17 years, it has been shown to be particularly effective in improving eczema of the face and neck, and its use may improve quality of life for many patients, especially children. A single-strength dose (1%) is safe and medically beneficial for pediatric, adolescent, and adult patients. The direct drug cost of pimecrolimus compares favorably with tacrolimus, but it is significantly more expensive than generic topical steroid creams.

Nonablative laser is gaining popularity because of the low risk of complications, especially in patients with darker skin. To compare the efficacy and safety of a long-pulse neodymium-doped yttrium aluminium garnet (Nd:YAG) laser and a combined 585/1,064-nm laser for the treatment of acne scars. Nineteen patients with mild to moderate atrophic acne scars received four long-pulse Nd:YAG laser or combined 585/1,064-nm laser treatment sessions at fortnightly intervals. Treatments were administered randomly in a split-face manner. Acne scars showed mild to moderate improvement, with significant Echelle d'évaluation clinique des cicatrices d'acné (ECCA) score reductions, after both treatments. Although intermodality differences were not significant, combined 585/1,064-nm laser was more effective for deep boxcar scars. In patients with combined 585/1,064-nm laser-treated sides that improved more than long-pulse Nd:YAG laser-treated sides, ECCA scores were significantly lower for combined 585/1,064-nm laser treatment. Histologic evaluations revealed significantly greater collagen deposition, although there was no significant difference between the two modalities. Patient satisfaction scores concurred with physicians' evaluations. Both lasers ameliorated acne scarring with minimal downtime. In light of this finding, optimal outcomes might be achieved when laser treatment types are chosen after considering individual scar type and response.

The present study examines onboard thermal microclimatic conditions and thermoregulation of pullets exposed to accidental hypothermia during wet-cold weather transportation conditions, and the effect of rewarming on colonic temperature (CT) of the birds immediately after transportation. A total of 2200 pullets were transportation for 5 h in two separate vehicles during the nighttime. The last 3 h of the transportation period was characterized by heavy rainfall. During the precipitation period, each vehicle was covered one fourth way from the top-roof with a tarpaulin. The onboard thermal conditions inside the vehicles during transportation, which comprised ambient temperature and relative humidity were recorded, while humidity ratio and specific enthalpy were calculated. The CT of the birds was recorded before and after transportation. During transportation, onboard thermal heterogeneity was observed inside the vehicles with higher ( p < 0.05) values in the front and center, and lower values recorded at the air inlets at the sides and rear planes. The CT values recorded in birds at the front and center planes were between 42.2 and 42.5 °C, indicative of mild hypothermia; while lower CT values between 28 and 38 °C were recorded at the sides and rear planes, indicative of mild to severe hypothermia. Several hours of gradual rewarming returned the CT to normal range. The result, for the first time, demonstrated the occurrence of accidental hypothermia in transported pullets under tropical conditions and a successful rewarming outcome. In conclusion, transportation of pullets during wet weather at onboard temperature of 18-20 °C induced hypothermia on birds located at the air inlets, which recovered fully after several hours of gradual rewarming.

2016-01-01

A field study was conducted to estimate the amount of Cr, Mn, and Ni deposited in the respiratory system of 44 welders in two facilities. Each worker wore a nanoparticle respiratory deposition (NRD) sampler during gas metal arc welding (GMAW) of mild and stainless steel and flux-cored arc welding (FCAW) of mild steel. Several welders also wore side-by-side NRD samplers and closed-face filter cassettes for total particulate samples. The NRD sampler estimates the aerosol's nano-fraction deposited in the respiratory system. Mn concentrations for both welding processes ranged 2.8–199 μg/m3; Ni concentrations ranged 10–51 μg/m3; and Cr concentrations ranged 40–105 μg/m3. Cr(VI) concentrations ranged between 0.5–1.3 μg/m3. For the FCAW process the largest concentrations were reported for welders working in pairs. As a consequence this often resulted in workers being exposed to their own welding fumes and to those generated from the welding partner. Overall no correlation was found between air velocity and exposure (R2 = 0.002). The estimated percentage of the nano-fraction of Mn deposited in a mild-steel-welder's respiratory system ranged between 10 and 56%. For stainless steel welding, the NRD samplers collected 59% of the total Mn, 90% of the total Cr, and 64% of the total Ni. These results indicate that most of the Cr and more than half of the Ni and Mn in the fumes were in the fraction smaller than 300 nm. PMID:25985454

Beclomethasone dipropionate (BDP) is a second-generation steroid with topical effects and minimal systemic activity for patients with ulcerative colitis (UC). To review all available literature to assess the efficacy of enema/foam BDP compared with enema/foam 5-aminosalicylic acid (5-ASA) in the control of left-sided mild-moderate UC. We selected randomized controlled trials of enema/foam BDP compared with enema/foam 5-ASA treatment in patients with UC. Two reviewers assessed trial quality and extracted data independently. Four trials involving 428 UC patients, 209 treated with 5-ASA (1-4 g o.d.) and 219 with BDP (3 mg o.d.), were included. Intention-to-treat analysis showed that 5-ASA induced improvement/remission of UC in 146 (69.9%) patients, while BDP in 143 (65.3%). The test for heterogeneity (Cochran Q) was not significant and Mantel-Haenszel pooled estimate of odds ratio was 1.23 (95% CI = 0.82-1.85). The results did not change when analysis was performed on a per-protocol basis. The randomized controlled trials identified in this review showed that rectal BDP has equal effect as 5-ASA to control symptoms in UC.

The number of psychotropic drugs has expanded tremendously over the past few decades with a proportional increase in drug-drug interactions. The majority of psychotropic agents are biotransformed by hepatic enzymes, which can lead to significant drug-drug interactions. Most drug-drug interactions of psychotropics occur at metabolic level involving the hepatic cytochrome P450 enzyme system. We searched the National Library of Medicine, PsycINFO, and Cochrane reviews from 1981 to 2012 for original studies including clinical trials, double-blind, placebo-controlled studies, and randomized controlled trials. In addition, case reports, books, review articles, and hand-selected journals were utilized to supplement this review. Based on the clinical intensity of outcome, cytochrome interactions can be classified as severe, moderate, and mild. Severe interactions include effects that might be acutely life threatening. They are mainly inhibitory interactions with cardiovascular drugs. Moderate interactions include efficacy issues. Mild interactions include nonserious side effects, such as somnolence. Psychotropic drugs may interact with other prescribed medications used to treat concomitant medical illnesses. A thorough understanding of the most prescribed medications and patient education will help reduce the likelihood of potentially fatal drug-drug interactions.

Aging effects, such as facial flatness, increased tissue laxity, and soft tissue descent and deflation, contribute to midface deficiency. To evaluate whether large gel particle hyaluronic acid with lidocaine (LGP-HAL) is more effective in the treatment of midface deficiencies than no treatment. Subjects with mild to substantial loss of midface fullness were randomized 3:1 to LGP-HAL (Restylane Lyft; Galderma Laboratories, L.P., Fort Worth, TX) or no treatment. Treatment success was defined as at least 1-grade improvement in Medicis Midface Volume Scale (MMVS) on each side of the face at 8 weeks as assessed by a blinded evaluator. Secondary efficacy end points included MMVS score, global aesthetic improvement, and subject satisfaction. Significantly greater percent of subjects achieved treatment success in the LGP-HAL group compared to no treatment at all time points through Month 12 (p < .001). One year after initial treatment, 85% of subjects still had a global aesthetic improvement assessed by the treating investigator. Subject satisfaction demonstrated that LGP-HAL improved the aesthetic appearance of the midface. Most reported adverse events (80%) were mild in severity. The LGP-HAL treatment is well tolerated and provides significant improvement up to 12 months for the correction of midface deficiencies.

Objective. This prospective open trial aimed to evaluate the efficacy and safety of isotretinoin (13-cis-retinoic acid) in patients with Cushing's disease (CD). Methods. Sixteen patients with CD and persistent or recurrent hypercortisolism after transsphenoidal surgery were given isotretinoin orally for 6–12 months. The drug was started on 20 mg daily and the dosage was increased up to 80 mg daily if needed and tolerated. Clinical, biochemical, and hormonal parameters were evaluated at baseline and monthly for 6–12 months. Results. Of the 16 subjects, 4% (25%) persisted with normal urinary free cortisol (UFC) levels at the end of the study. UFC reductions of up to 52.1% were found in the rest. Only patients with UFC levels below 2.5-fold of the upper limit of normal achieved sustained UFC normalization. Improvements of clinical and biochemical parameters were also noted mostly in responsive patients. Typical isotretinoin side-effects were experienced by 7 patients (43.7%), though they were mild and mostly transient. We also observed that the combination of isotretinoin with cabergoline, in relatively low doses, may occasionally be more effective than either drug alone. Conclusions. Isotretinoin may be an effective and safe therapy for some CD patients, particularly those with mild hypercortisolism. PMID:27034666

To assess the effectiveness and safety of a 24-week application of tretinoin 0.025% cream, with an alternate-day regimen, in achieving control of VLS signs and symptoms. 17 patients affected with VLS were included. The main efficacy parameters were the response rate, as defined by protocol parameters, the rate of patients achieving an improvement from baseline of ≥75% in the subjective and objective scores, and the mean reduction in subjective and objective scores throughout the treatment. The safety of the treatment was also assessed. By the end of the 24-week treatment, 12 patients (70.6%) experienced a response; 35.3% and 17.6% of patients achieved an improvement of at least 75% in subjective and objective scores, respectively. Mean scores of itching, leukoderma (pallor) and hyperkeratosis decreased significantly in the study patients, and none presented itching-related excoriations. Erythema increased compared with baseline. Six patients (35.29%) experienced some side effects related to tretinoin, mainly mild erythema and burning. None of the subjects discontinued the treatment because of side effects. Tretinoin 0.025% cream applied for 24 weeks may represent a useful alternative option to corticosteroids in the treatment of active VLS, acting particularly on hyperkeratosis and pallor.

At present, therapy of children with chronic hepatitis B and C is still based on few drugs, all burdened by a series of side-effects, unsatisfactory serum conversion rates, and/or drug-resistance. Moreover, selection of subjects to treat with conventional therapies is not univocal, especially during the pediatric age when the disease course is often mild with significant spontaneous seroconversion rate. Our review deals with pros and cons points when a physician decides to design a drug therapy for a child with chronic viral hepatitis, and different possible therapeutic opportunities. A literature search was performed through PubMed. The newest articles, reviews, systematic reviews, and guidelines were included in this review. The management of children with viral hepatitis is still controversial over whom and when to treat and the use of drug(s). Novel therapeutic strategies have been evaluated only in clinical and preclinical trials involving, for instance, "therapeutic" vaccines. The data on safety and effectiveness of new drugs are also reviewed. The results of reported studies confirmed that at least some of the new drugs, with greater efficacy and/or minor side-effects, will be used clinically.

Dexmedetomidine: a novel sedative-analgesic agent

PubMed Central

2001-01-01

Since the first report of clonidine, an α2-adrenoceptor agonist, the indications for this class of drugs have continued to expand. In December 1999, dexmedetomidine was approved as the most recent agent in this group and was introduced into clinical practice as a short-term sedative (<24 hours). α2-Adrenoceptor agonists have several beneficial actions during the perioperative period. They decrease sympathetic tone, with attenuation of the neuroendocrine and hemodynamic responses to anesthesia and surgery; reduce anesthetic and opioid requirements; and cause sedation and analgesia. They allow psychomotoric function to be preserved while letting the patient rest comfortably. With this combination of effects, α2-adrenoceptor agonists may offer benefits in the prophylaxis and adjuvant treatment of perioperative myocardial ischemia. Furthermore, their role in pain management and regional anesthesia is expanding. Side effects consist of mild to moderate cardiovascular depression, with slight decreases in blood pressure and heart rate. The development of new, more selective α2-adrenoceptor agonists with improved side effect profiles may provide a new concept for the administration of perioperative anesthesia and analgesia. This review aims to give background information to improve understanding of the properties and applications of the novel α2-adrenoceptor agonist, dexmedetomidine. PMID:16369581

Pseudogynecomastia refers to benign male breast enlargement due to excess subareolar fat. Standard treatment is surgical excision under general anesthesia, liposuction, or a combination of both. The safety and efficacy of cryolipolysis was investigated for nonsurgical treatment of pseudogynecomastia. Enrollment consisted of 21 males with pseudogynecomastia. Subjects received a first treatment consisting of a 60-minute cryolipolysis cycle, followed by a two-minute massage, and a second 60-minute cycle with 50% treatment area overlap. At 60 days of follow-up, subjects received a second 60-minute treatment. Safety was evaluated by monitoring side effects and adverse events. Efficacy was assessed by ultrasound, clinical photographs, and subject surveys. Surveys revealed that 95% of subjects reported improved visual appearance and 89% reported reduced embarrassment associated with pseudogynecomastia. Ultrasound showed mean fat layer reduction of 1.6 ± 1.2 mm. Blinded reviewers correctly identified 82% of baseline photographs. Side effects included mild discomfort during treatment and transient paresthesia and tenderness. One case of paradoxical hyperplasia (PH) occurred but likelihood of PH in the male breast is not believed to be greater than in any other treatment area. This study demonstrated feasibility of cryolipolysis for safe, effective, and well-tolerated nonsurgical treatment of pseudogynecomastia.

To explore the efficacy and side effects of icotinib hydrochloride in the treatment of patients with advanced non-small cell lung cancer (NSCLC). The efficacy and side effects of icotinib hydrochloride in treatment of 59 cases with stage IV NSCIC and followed-up from March 2009 to January 2012 were retrospectively analyzed. Twenty seven patients (45.8%) showed partial response (PR), 17 patients (28.8%) achieved SD, and 15 (25.4%) had progressive disease. The objective response rate (ORR) was 45.8% (27/59), and disease control rate (DCR) was 74.6% (44/59). Among the 23 patients with EGFR mutation, ORR was 73.9% (17/23), and DCR was 95.7% (22/23). Thirty six patients (61.0%) achieved remission of symptoms to varying degrees. The main symptoms relieved were cough, asthmatic suffocating, pain and hoarseness. The major adverse events were mild skin rash (35.6%) and diarrhea (15.3%). Others were dry skin, nausea and stomach problems. The efficacy of icotinib hydrochloride were related to the ECOG performance status, smoking history, EGFR mutation and rash significantly (P < 0.05). Monotherapy with icotinib hydrochloride is effective and tolerable for patients with advanced NSCLC, especially with EGFR mutation.

In obstructive sleep apnea patients (OSA), continuous positive airway pressure (CPAP) adherence is crucial to improve symptoms and cardiometabolic outcomes. The choice of mask may influence CPAP adherence but this issue has never been addressed properly. To evaluate the impact of nasal pillows, nasal and oronasal masks on CPAP adherence in a cohort of OSA. Newly CPAP treated OSA participating in "Observatoire Sommeil de la Fédération de Pneumologie", a French national prospective cohort, were included between March 2009 and December 2011. Anthropometric data, medical history, OSA severity, sleepiness, depressive status, treatment modalities (auto-CPAP versus fixed pressure, pressure level, interface type, use of humidifiers) and CPAP-related side effects were included in multivariate analysis to determine independent variables associated with CPAP adherence. 2311 OSA (age = 57(12) years, apnea+hypopnea index = 41(21)/h, 29% female) were included. Nasal masks, oronasal masks and nasal pillows were used by 62.4, 26.2 and 11.4% of the patients, respectively. In univariate analysis, oronasal masks and nasal pillows were associated with higher risk of CPAP non-adherence. CPAP non-adherence was also associated with younger age, female gender, mild OSA, gastroesophageal reflux, depression status, low effective pressure and CPAP-related side effects. In multivariate analysis, CPAP non-adherence was associated with the use of oronasal masks (OR = 2.0; 95%CI = 1.6; 2.5), depression, low effective pressure, and side effects. As oronasal masks negatively impact on CPAP adherence, a nasal mask should be preferred as the first option. Patients on oronasal masks should be carefully followed.

Purpose: Mental health is the level of psychological well being and encompasses the abilities to develop emotionally, psychologically, intellectually, socially and spiritually. There is no health without mental health. Most common mental disorder is depression, anxiety & drug addiction. Major depressive disorder is a mental disorder characterised by an all encompassing low mood accompanied by low self esteem and loss of interest in normally enjoyable activities. Standard treatment for depression includes antidepressant medication which have unpleasant side effect and psychotherapy which is time consuming and expensive. Objective of the present study was to assess the effectiveness of a herbal preparation and shirodhara therapy for the treatment of major depressive disorder and to compare its effectiveness with a standard drug. Method: It was Open Randomised Controlled clinical Study. Study population was selected from OPD & IPD of Kaychikitsa department at NIA and OPD of Psychiatry, SMS Medical College & Hospital, Jaipur. Out of 42 screened patients, 30 patients fulfilling the DSM-IV criteria for diagnosis of depression were enrolled for the study and randomly divided into two groups. Group A was given standard drug fluoxetine 20mg orally BD for 42 days. Group B was given herbal preparation orally for 42 days with shirodhara by medicated plain Ashwagandha oil for 14 days. Observations were made on baseline day, 14thday, and 28thday and 42nd day of study. Result: Both the groups showed significant improvement, with no unpleasant side effect in Group B. Conclusion: Selected Herbal preparation and Shirodhara therapy can be used in mild & moderate condition of major depression with free of side effect.

The efficacy in acute migraine of oral sumatriptan was assessed in a double-blind, randomised, placebo-controlled, crossover study of 61 patients (mean age 39 [SD 10] years). 41 completed treatment of four attacks, two with sumatriptan 100 mg and two with placebo. The response rate (reduction in headache from moderate or severe to mild or absent at 2 h) was 51% (45/89) with sumatriptan and 10% (9/93) with placebo (p less than 0.01); rescue medication was needed at 2 h in 41% and 88%, respectively. Of 28 patients headache-free at 24 h, 11 (39%) had recurrent headache within 24 h. There were no substantial side-effects. Thus, sumatriptan is an effective well-tolerated treatment for acute migraine attacks.

The high prevalence of acne vulgaris in teenagers has increased comorbidities. Lasers offer alternative options for acne treatment because they have rapid action, low systemic adverse effects, and do not require everyday treatment. To study the efficacy and patients' satisfaction of 595-nm pulse dye laser (PDL) treatment of acne vulgaris and acne erythema in adolescents and early adulthood, we designed a blocked-randomized, split-faced 595-nm PDL (fluence 8 J/cm 3 pulse duration 10 ms, spot size 7 mm, 2 session every 2 weeks) study in patients with mild to moderate acne by comparing the laser-treated and non-treated side. The acne lesion counts, acne erythema grading, and acne severity grading were evaluated at baseline and 2, 4, and 8 weeks. Thirty patients were recruited. The results showed no statistically significant difference except the papule count at week 4 which was -1.828 on the treated side and 0.103 on the non-treated side of the face, P-value 0.0018. There was no statistically significant difference of acne severity grading and acne erythema grading between both sides of the face. The mean scores of patients' satisfaction on the laser-treated side were 75, 81, and 81%, respectively. The PDL treatment in this study reveals no significant improvement in acne therapy; however, the patients were satisfied with this laser treatment. © 2017 The International Society of Dermatology.

Background: Mirror movements (MM) are not widely appreciated in parkinsonism and no report has evaluated this clinical sign in detail. Objectives: To define the parkinsonian clinical features associated with MM in patients with early, asymmetric parkinsonism. Methods: Twenty seven patients with early Parkinson's disease were evaluated using a standardised videotaping protocol. MM were scored from blinded video assessment using a clinical scale that rates the amplitude, distribution, and proportion of mirroring in the less affected limb. Parkinsonian features were combined into axial and lateralised scores using related items of the Unified Parkinson's Disease Rating Scale. Results: MM were present in 24 of 27 patients. There was a significant linear correlation between the degree of asymmetry of motor deficits and MM on the less affected side. The effect of asymmetry was greater when the proportional rather than the absolute motor difference between sides was largest. Asymmetry in leg rigidity was the most important examination feature in the prediction of contralateral foot mirroring. Conclusions: MM are a clinical feature of the unaffected or less affected side in mild asymmetric parkinsonism. Their presence may be a useful clinical finding in early parkinsonism. PMID:16170075

Direct numerical simulation of turbulence in a bent pipe

Schlatter, Philipp; Noorani, Azad

2013-11-01

A series of direct numerical simulations of turbulent flow in a bent pipe is presented. The setup employs periodic (cyclic) boundary conditions in the axial direction, leading to a nominally infinitely long pipe. The discretisation is based on the high-order spectral element method, using the code Nek5000. Four different curvatures, defined as the ratio between pipe radius and coil radius, are considered: κ = 0 (straight), 0.01 (mild curvature), 0.1 and 0.3 (strong curvature), at bulk Reynolds numbers of up to 11700 (corresponding to Reτ = 360 in the straight pipe case). The result show the turbulence-reducing effect of the curvature (similar to rotation), leading close to relaminarisation in the inner side; the outer side, however, remains fully turbulent. Prpoer orthogonal decomposition (POD) is used to extract the dominant modes, in an effort to explain low-frequency switching of sides inside the pipe. A number of additional interesting features are explored, which include sub-straight and sub-laminar drag for specific choices of curvature and Reynolds number: In particular the case with sub-laminar drag is investigated further, and our analysis shows the existence of a spanwise wave in the bent pipe, which in fact leads to lower overall pressure drop.

Migraine headache is a neurologic disorder that occurs in 18% of women and 6% of men. Adults and children with mild to moderate migraine headaches seeking acute therapy should be treated with nonsteroidal anti-inflammatory drugs because of the efficacy, cost, and decreased side effects. Some children and adults require preventive therapy (those with headaches lasting >12 h, those patients with >4 headaches in 1 month, those with headaches that affect their ability to function). Studies have shown that early treatment with large doses of medication work well for the treatment of moderate to severe migraine headache. Copyright © 2015 Elsevier Inc. All rights reserved.

An approach to the synthesis of the (iso)cyclocitrinol core structure is described. The key step is a tandem Ireland Claisen/Cope rearrangement sequence, wherein the Ireland Claisen rearrangement effects ring contraction to a strained 10-membered ring, and that strain in turn drives the Cope rearrangement under unusually mild thermal conditions. A major side product was identified as resulting from an unexpected and remarkably facile [1,3]-sigmatropic rearrangement, and a tactic to disfavor the [1,3] pathway and increase the efficiency of the tandem reaction was rationally devised.

Melatonin is commonly recommended to treat sleep problems in children with developmental disabilities. However, few studies document the efficacy and safety of melatonin in these populations. This article reviews recent studies of melatonin efficacy in developmental disabilities. Overall, short treatment trials were associated with a significant decrease in sleep onset latency time for each of the disorders reviewed, with 1 notable exception-tuberous sclerosis. Reported side effects were uncommon and mild. Across disorders, additional research is needed to draw disability-specific conclusions. However, studies to date provide positive support for future trials that include larger groups of children with specific disabilities/syndromes. Copyright © 2015 Elsevier Inc. All rights reserved.

Acne vulgaris is the most common disease of the adolescence age (70-94%). Main topical treatments for acne vulgaris are retinoids, benzoyl peroxide and antibiotics in mono or combination therapy. Topical retinoids, some antibiotics and antiseptics although effective on acne lesions, can due photosensitivity or make the skin more sensitive to the sun. Our study is aimed to evaluate the efficacy and tolerability of a combination therapy with Retinaldheyde (0.1%), Glycolic acid (6%) and Efectiose (0.1%) (RGE) cream in patients affected by acne vulgaris, during the lasting period of sun exposure. We retrospectively observed 30 patients of Central Italy with mild or moderate acne between April and September. All the patients selected underwent only therapy with RGE cream once a day in the evening for 8 weeks, while in the morning they just applied SPF 50 sunscreen. We evaluate the efficacy at 30 and 60 days with the "Global Evaluation Scale" (GES) and the tolerability with a 0-3 qualitative scale. The mean GES value showed a statistically significant reduction: 1.83 (SD 0.83) at baseline 1.57 (SD 0.77) and 0.90 (SD 0.76) respectively at 30 and 60 days (p < 0.01). Side effects were very uncommon. Topical treatments with retinoids, antibiotics and antiseptics can be associated with an increased occurrence of facial dryness and erythema restricting their use in sun exposure period. RGE cream has shown a good skin tolerability and efficacy, so it can be considerate an effective maintaining therapy to treat mild to moderate acne during the sun exposure period in which retinoids, antibiotics or antiseptic treatments are not recommended.

Background Public health interventions based on distribution of anthelminthic drugs against lymphatic filariasis (LF), onchocerciasis, soil-transmitted helminthiasis (STH) and schistosomiasis have been implemented separately to date. A better use of available resources might be facilitated by a more coordinated approach to control such infections, including the possibility of co-administering the three recommended anthelminthic drugs through a single, large-scale intervention. Methodology/Principal Findings Ivermectin, albendazole and praziquantel were co-administered to 5,055 children and adults living in areas endemic for LF, STH and schistosomiasis in Zanzibar, United Republic of Tanzania, during a pilot intervention aimed at elucidating and quantifying possible side-effects. Subsequently, these drugs were co-administered to about 700,000 individuals during a countrywide intervention targeting a large part of the total population of Zanzibar. Passive and active surveillance measures carried out during both interventions showed that side-effects attributable to the three drugs given at the same time were mild and self-limiting events. Conclusions/Significance Our data suggest that co-administration of ivermectin, albendazole and praziquantel is safe in areas where lymphatic filariasis, soil-transmitted helminthiasis and schistosomiasis are co-endemic and where several rounds of treatment with one or two drugs have been implemented in the past. Passive surveillance measures, however, should be continued and detection, management and reporting of possible side-effects should be considered a key component of any health intervention administering drugs.

We report a 58-year-old man showing spastic paraparesis due to medulla oblongata compression by tortuous vertebral arteries. He noticed weakness of both legs and gait disturbance at the age of 58 years and his symptoms progressively worsened during the following several months. General physical findings were normal. Blood pressure was normal and there were no signs of arteriosclerosis. Neurological examination on admission revealed lower-limb-dominant spasticity in all four extremities, lower-limb weakness, hyperreflexia in all extremities with positive Wartenberg's, Babinski's and Chaddock's signs, mild hypesthesia and hypopallesthesia in both lower limbs, and spastic gait. Cranial nerves were all normal. Serum was negative for antibodies against human T-cell lymphotropic virus-1 antibody. Nerve conduction and needle electromyographic studies of all four limbs revealed normal findings. Cervical, thoracic and lumbo-sacral magnetic resonance imaging (MRI) findings were all normal. Brain MRI and magnetic resonance angiography demonstrated bilateral tortuous vertebral arteries compressing the medulla oblongata. Neurovascular decompression of the right vertebral artery was performed because compression of the right side was more severe than that of the left side. Post-operative MRI revealed outward translocation of the right vertebral artery and relieved compression of the medulla oblongata on the right side. The patient's symptoms and neurological findings improved gradually after the operation. Bilateral pyramidal tract signs without cranial nerve dysfunction due to compression of the medulla oblongata by tortuous vertebral arteries are extremely rare and clinically indistinguishable from hereditary spastic paraplegia (HSP). Although we did not perform a genetic test for HSP, we consider that the spastic paraparesis and mild lower-limb hypesthesia were caused by compression of the medulla oblongata by bilateral tortuous vertebral arteries based on the post-operative improvement in symptoms. Given the favorable effects of surgery, tortuous vertebral arteries should be considered in the differential diagnosis of patients presenting with progressive spastic paraparesis.

Treatment adherence and real-life effectiveness of topical therapy in patients with mild or moderate psoriasis: uptake of scientific evidence in clinical practice and dermatologists' preferences for alternative treatment options.

Topical corticosteroids and the vitamin D analogue calcipotriol are the cornerstone of therapy for patients with mild-to-moderate plaque psoriasis. Lack of patients' adherence leads to suboptimal effectiveness of topical therapy in real-life practice. The fixed combination betamethasone/calcipotriol gel is more effective and safe than the administration of single components and may enhance patients' adherence. We aimed at evaluating the pattern of care and dermatologists' expert opinion toward the available topical treatments for the management of mild-to-moderate psoriasis in Italy. We enrolled 242 Italian dermatologists and collected information related to their practice pattern and opinion toward available topical treatments with a face-to-face structured interview. We evaluated dermatologists' ratings of therapy with 16 items tapping their opinion toward the relevance and satisfaction toward 8 therapy attributes in clinical practices which tapped aspects of real-life effectiveness, adherence promotion, toxicity, convenience of use. Ratings occurred along a 10-point scale. We compared single-attribute and weighted overall therapy ratings across alternative treatment options with random-intercept linear models to account for ratings clustering within dermatologists. There was a wide variation in practice patterns: 1/3 of dermatologist had seen more than 30 patients with psoriasis while around 1/4 had seen less than 10 patients. The fixed combination betamethasone/calcipotriol gel was considered superior to monotherapies in all the eight attributes considered which tapped aspects of real-life effectiveness, adherence promotion, toxicity, convenience of use. Participant dermatologists' strongly preferred the fixed betamethasone/calcipotriol combination gel over both the fixed combination ointment formulation and corticosteroid or vitamin D analogues monotherapies. Such findings are in line with evidence from randomized controlled trials and few observational studies demonstrating superior clinical outcomes, quality of life, tolerability and lower risk of side effect in patients treated with the fixed combination of betamethasone/calcipotriol gel.

Objective To compare a 2 day bowel preparation regime of barium, iodine and a mild stimulant laxative with a 1 day iodine-only regime for CT colonography (CTC). Methods 100 consecutive patients underwent CTC. The first 50 patients (Regime 1) ingested 1 bisacodyl tablet twice a day 3 days before CTC and 1 dose each of 50 ml of barium and 20 ml of iodinated contrast per day starting 2 days before CTC. The second 50 patients (Regime 2) ingested 3 doses of iodinated contrast over 24 h prior to CTC. Volumes of residual stool and fluid, and the effectiveness of stool and fluid tagging, were graded according to methods established by Taylor et al (Taylor S, Slaker A, Burling D, Tam E, Greenhalgh R, Gartner L, et al. CT colonography: optimisation, diagnostic performance and patient acceptability of reduced-laxative regimens using barium-based faecal tagging. Eur Radiol 2008; 18: 32–42). A 3 day low-residue diet was taken by both cohorts. Questionnaires rating the side-effects and burden of the bowel preparation were compared to a control cohort of patients undergoing barium enema. Results The proportion of colons producing none/scattered stool (score 1) was 90.3% with Regime 1 and 65.0% with Regime 2 (p<0.005). Any residual stool was significantly better tagged with Regime 1 (score 5), with 91.7% of Regime 1 exhibiting optimum tagging vs 71.3% of Regime 2 (p<0.05). No significant differences in side-effects between the bowel preparation regimes for CTC were elicited. Bowel preparation for barium enema was tolerated significantly worse than both of the CTC bowel preparation regimes. Conclusion Regime 1, containing a 3 day preparation of a mild laxative, barium and iodine, produced a significantly better prepared colon, with no difference in patient acceptability. PMID:22422379

Allergic rhinitis (AR) is the most common manifestation of atopic reaction to inhaled allergens. It is a chronic inflammatory disease which may first appear at any age, but the onset is usually during childhood or adolescence. Up to date there is no curative treatment for this disorder and most of the drugs that were used for treatment only can induce symptomatic relief and some of them have side effect and can cause withdrawal symptoms. To evaluate the therapeutic efficacy of the Nigella sativa (NS) extract as treatment approach for allergic rhinitis. A total of 68 patients with AR were included in the study, of them 19 patients were with mild symptoms, 28 patients were with moderate symptoms and 21 patients were with severe symptoms. Each group was subdivided into active and control subgroups. To prove that the patient's symptoms were allergic in nature, skin test was performed for all patients. Any individual with negative skin test was excluded. The individuals in the active group received N. sativa oil and the control group individuals received ordinary food oil in the form of nasal drops for 6 weeks. After the 6 weeks treatment course, 100% of the patients in the mild active group became symptoms free; while in moderate active group 68.7% became symptoms free and 25% were improved; while in severe active group 58.3% became symptoms free and 25% were improved. In addition, 92.1% of total patients in the active group demonstrated improvement in their symptoms or were symptoms free, while the corresponding value was 30.1% in the control group (P=0.000). At the end of 6 weeks of treatment with topical use, the improvement in tolerability of allergen exposure in active group became 55.2% which was significant (P=0.006) as compared with control group which was accounted for 20% at the same time. Topical application of black seed oil was effective in the treatment of allergic rhinitis, with minimal side effects.

Because clothing has the longest and most direct contact with human skin, it is important to carefully choose suitable fabrics for atopic patients who have disrupted skin. To evaluate the clinical effectiveness and biophysical properties of a newly developed silver-loaded cellulose fabric with incorporated seaweed, we enrolled 12 subjects with mild to moderate atopic dermatitis into a clinical control study. The subjects wore a two-piece garment (top and leggings), each piece of which was divided into two parts: one side was made of SkinDoctor(®) fabric, and the other of 100% cotton. Treatment efficacy was measured with the modified SCORing Atopic Dermatitis (mSCORAD) index, transepidermal water loss (TEWL) and the patients' subjective impressions. All three of these measures had significantly better scores on the side covered with SkinDoctor. These results suggest that SkinDoctor is a beneficial fabric that can improve the comfort of patients with AD. © The Author(s). CED © 2012 British Association of Dermatologists.

To determine whether there is a relationship between electroencephalography patterns and hypoglycemia, by using simultaneous cot-side amplitude integrated electroencephalography (aEEG) and continuous interstitial glucose monitoring, and whether non-glucose cerebral fuels modified these patterns. Eligible babies were ≥ 32 weeks gestation, at risk for hypoglycemia, and admitted to the neonatal intensive care unit. Electrodes were placed in C3-P3, C4-P4 O1-O2 montages. A continuous interstitial glucose sensor was placed subcutaneously, and blood glucose was measured by using the glucose oxidase method. Non-glucose cerebral fuels were measured at study entry, exit, and during recognized hypoglycemia. A total of 101 babies were enrolled, with a median weight of 2179 g and gestation of 35 weeks. Twenty-four of the babies had aEEG recordings, and glucose concentrations were low (< 2.6 mM). There were 103 episodes of low glucose concentrations lasting 5 to 475 minutes, but no observable changes in aEEG variables. Plasma concentrations of lactate, beta-hydroxybutyrate, and glycerol were low and did not alter during hypoglycemia. Cot-side aEEG was not useful for the detection of neurological changes during mild hypoglycemia. Plasma concentrations of non-glucose cerebral fuels were low and unlikely to provide substantial neuroprotection. Copyright © 2011 Mosby, Inc. All rights reserved.

Pharmacological management of feline hyperthyroidism offers a practical treatment option for many hyperthyroid cats. Two drugs have been licensed for cats in the last decade: methimazole and its pro-drug carbimazole. On the basis of current evidence and available tablet sizes, starting doses of 2·5 mg methimazole twice a day and 10 to 15 mg once a day for the sustained release formulation of carbimazole are recommended. These doses should then be titrated to effect in order to obtain circulating total thyroxine (TT4) concentrations in the lower half of the reference interval. Treated cases should be monitored for side-effects, especially during the first months of treatment. Some side-effects may require discontinuation of treatment. At each monitoring visit, clinical condition and quality of life should also be evaluated, with special attention to possible development of azotaemia, hypertension and iatrogenic hypothyroidism. When euthyroidism has been achieved, monitoring visits are recommended after 1 month, 3 months and biannually thereafter. Cats with pre-existing azotaemia have shorter survival times. However, development of mild azotaemia during the initial course of treatment, unless associated with hypothyroidism, does not appear to decrease survival time. The long-term effects of chronic medical management require further study. © 2013 British Small Animal Veterinary Association.

Oxcarbazepine: a new drug in the management of intractable trigeminal neuralgia.

Zakrzewska, J M; Patsalos, P N

1989-01-01

The efficacy and tolerability of oxcarbazepine, a keto derivative of carbamazepine, has been assessed in six patients (two males, four females; mean age 61 years, range 42-77), with trigeminal neuralgia refractory to carbamazepine therapy, over a period of 6 months. An excellent therapeutic response to oxcarbazepine was seen in all patients with pain control correlating well with serum drug concentrations of oxcarbazepine and its primary active metabolite 10-OH-carbazepine. Onset of the effect was observed within 24 hours in all cases. An overall serum therapeutic concentration range, in the six patients, of 50-110 mumol/l of 10-OH-carbazepine corresponding to a daily effective dose range of 1200-2400 mg (14.6-35.6 mg/kg body weight) oxcarbazepine, was observed. There was a significant correlation between oxcarbazepine dose and serum oxcarbazepine (r = 0.695, p less than 0.05) and 10-OH-carbazepine (r = 0.957, p less than 0.001) concentrations. Oxcarbazepine was well tolerated and no significant side effects were identified, though a mild hyponatraemia was observed during high doses (greater than 28 and greater than 35 mg/kg/day) in two patients. It is concluded that oxcarbazepine has potent antineuralgic properties in the absence of significant side effects and therefore may be useful in the management of intractable trigeminal neuralgia.

The purpose of this study was evaluation of the safety and efficacy of this new combined technology that adds deep ablation to thermal stimulation. Minimally ablative or subablative lasers, such as fractional CO2 lasers, have been developed in an attempt to achieve the same clinical results observed with traditional ablative lasers, but with fewer side effects. Despite being an ablative laser, the system used in this study is able to produce a fractional supply of the beam of light. Fractional ablation of skin is performed through the development of microscopic vertical columns surrounded by spared areas of epidermis and dermis, ensuring rapid wound healing and minimum down time. Simultaneous synchronized delivery of a radiofrequency (RF) current to the deeper layers of the skin completes the therapeutic scenario, ensuring an effective skin tightening effect over the entire treated area. Nine adult patients were treated for wrinkles and acne scars using this new laser technology. An independent observer evaluated the improvement using a five point scale. All patients had good results in terms of improvement of skin texture, with mild and transitory side effects. This novel combined system produced improvement in wrinkles and acne scars, with progressive enhancement of skin tone and elasticity.

Purpose: Oncoming headlight glare (HLG) reduces the visibility of objects on the road and may affect the safety of nighttime driving. With cataracts, the impact of oncoming HLG is expected to be more severe. We used our custom HLG simulator in a driving simulator to measure the impact of HLG on pedestrian detection by normal vision subjects with simulated mild cataracts and by patients with real cataracts. Methods: Five normal vision subjects drove nighttime scenarios under two HLG conditions (with and without HLG: HLGY and HLGN, respectively), and three vision conditions (with plano lens, simulated mild cataract, and optically blurred clip-on). Mild cataract was simulated by applying a 0.8 Bangerter diffusion foil to clip-on plano lenses. The visual acuity with the optically blurred lenses was individually chosen to match the visual acuity with the simulated cataract clip-ons under HLGN. Each nighttime driving scenario contains 24 pedestrian encounters, encompassing four pedestrian types; walking along the left side of the road, walking along the right side of the road, crossing the road from left to right, and crossing the road from right to left. Pedestrian detection performances of five patients with mild real cataracts were measured using the same setup. The cataract patients were tested only in HLGY and HLGN conditions. Participants’ visual acuity and contrast sensitivity were also measured in the simulator with and without stationary HLG. Results: For normal vision subjects, both the presence of oncoming HLG and wearing the simulated cataract clip-on reduced pedestrian detection performance. The subjects performed worst in events where the pedestrian crossed from the left, followed by events where the pedestrian crossed from the right. Significant interactions between HLG condition and other factors were also found: (1) the impact of oncoming HLG with the simulated cataract clip-on was larger than with the plano lens clip-on, (2) the impact of oncoming HLG was larger with the optically blurred clip-on than with the plano lens clip-on, but smaller than with the simulated cataract clip-on, and (3) the impact was larger for the pedestrians that crossed from the left than those that crossed from the right, and for the pedestrians walking along the left side of the road than walking along the right side of the road, suggesting that the pedestrian proximity to the glare source contributed to the performance reduction. Under HLGN, almost no pedestrians were missed with the plano lens or the simulated cataract clip-on (0 and 0.5%, respectively), but under HLGY, the rate of pedestrian misses increased to 0.5 and 6%, respectively. With the optically blurred clip-on, the percent of missed pedestrians under HLGN and HLGY did not change much (5% and 6%, respectively). Untimely response rate increased under HLGY with the plano lens and simulated cataract clip-ons, but the increase with the simulated cataract clip-on was significantly larger than with the plano lens clip-on. The contrast sensitivity with the simulated cataract clip-on was significantly degraded under HLGY. The visual acuity with the plano lens clip-on was significantly improved under HLGY, possibly due to pupil myosis. The impact of HLG measured for real cataract patients was similar to the impact on performance of normal vision subjects with simulated cataract clip-ons. Conclusion: Even with mild (simulated or real) cataracts, a substantial negative effect of oncoming HLG was measurable in the detection of crossing and walking-along pedestrians. The lowered pedestrian detection rates and longer response times with HLGY demonstrate a possible risk that oncoming HLG poses to patients driving with cataracts. PMID:29559933

The aim of this randomized controlled trial was to assess the efficacy of a cream containing ceramides and magnesium (Cer-Mg) in the treatment of mild to moderate atopic dermatitis and to compare it with hydrocortisone and a commonly used emollient (unguentum leniens; cold cream). A total of 100 patients, randomized into 2 groups, were treated for 6 weeks simultaneously (left vs. right side of the body) with either Cer-Mg and hydrocortisone (group I) or Cer-Mg and emollient (group II). The primary outcome was a reduction in severity of lesions as assessed by (local) SCORAD (SCORing Atopic Dermatitis). Levels of trans-epidermal water loss (TEWL), skin hydration, and natural moisturizing factors (NMF) were then measured. After 6 weeks, group I showed comparable significant improvement in SCORAD and TEWL, while in group II, the decrease in SCORAD and TEWL was significantly greater after Cer-Mg compared with emollient. Finally, Cer-Mg cream was more effective in improving skin hydration and maintenance of levels of NMF than hydrocortisone and emollient.

Rationale Airway inflammation is central to cystic fibrosis (CF) pathophysiology. Pre-clinical models have shown that phosphodiesterase inhibitors (PDEi) like sildenafil have anti-inflammatory activity. PDEi have not been studied in CF subjects. Objectives We evaluated the pharmacokinetics, tolerability, and safety of sildenafil in subjects with CF. Sputum biomarkers were used to explore efficacy. Methods An open-label pilot study of oral sildenafil administration was conducted in adults with mild to moderate CF lung disease. Subjects received oral sildenafil 20 or 40 mg p.o. t.i.d. for 6 weeks. Measurements and Main Results Twenty subjects completed the study. Estimated elimination rate constants were statistically different in subjects with CF compared to previously published non-CF subjects. Side effects were generally mild. There were no drug-related serious adverse events. Sputum neutrophil elastase activity decreased. Conclusions Subjects with CF may eliminate sildenafil at a faster rate than non-CF subjects. Sildenafil administration was safe in subjects with CF, and decreased sputum elastase activity. Sildenafil warrants further study as an anti-inflammatory in CF. PMID:25466700

We aimed to explore the prevalence of and risk factors for depressive symptoms (DS) among people living with HIV/AIDS (PLWHA) receiving antiretroviral treatment (ART) in Wuhan, Hubei, China. A cross-sectional study evaluating adult PLWHA receiving ART in nine designated clinical hospitals was conducted from October to December 2015. The validated Beck Depression Inventory (BDI) was used to assess DS in eligible participants. Socio-demographical, epidemiological and clinical data were directly extracted from the case reporting database of the China HIV/AIDS Information Network. Multinomial regression analysis was used to explore the risk factors for DS. 394 participants were finally included in all analyses. 40.3% were found to have DS with 13.7% having mild DS and 26.6% having moderate to severe DS. The results of multinomial regression analysis suggested that being married or living with a partner, recent experience of ART-related side effects, and/or history of HCV infection were positively associated with mild DS, while increasing age was positively associated with moderate to severe DS.

Alzheimer's disease (AD) is a neurodegenerative disorder that causes cortical atrophy and impaired cognitive functions. The diagnosis is difficult to make and is often made over a longer period of time using a combination of neuropsychological tests, and structural and functional imaging. Due to the impact of early intervention the challenge of distinguishing early AD from normal ageing has received increasing attention. This study uses cortical thickness measurements to characterize the atrophy in nine mild AD patients (mean MMSE-score 23.3 (std: 2.6)) compared to five healthy middle-aged subjects. A fully automated method based on deformable models is used for delineation of the inner and outer boundaries of the cerebral cortex from Magnetic Resonance Images. This allows observer independent high-resolution quantification of the cortical thickness. The cortex analysis facilitates detection of alterations throughout the entire cortical mantle. To perform inter-subject thickness comparison in which the spatial information is retained, a feature-based registration algorithm is developed which uses local cortical curvature, normal vector, and a distance measure. A comparison of the two study groups reveals that the lateral side of the hemispheres shows diffuse thinner areas in the mild AD group but especially the medial side shows a pronounced thinner area which can be explained by early limbic changes in AD. For classification principal component analysis is applied to reduce the high number of thickness measurements (>200,000) into fewer features. All mild AD and healthy middle-aged subjects are classified correctly (sensitivity and specificity 100%).

Blood Levels and Management of Lithium Treatment

PubMed Central

Crammer, John L.; Rosser, Rachel M.; Crane, Graham

1974-01-01

The limited value of plasma measurements in the management of treatment with lithium is discussed in the light of the mechanisms of its therapeutic actions and toxic effects. The plasma level of lithium usually rises twofold or threefold in the three to five hours after ingestion of each dose of delayed-release tablets and then gradually falls. The precise shape and height of the lithium curve depend on gastric emptying, which can be slowed with propantheline or speeded with metoclopramide. Depressed or demented patients may be irregular in taking their tablets and variable in food intake. Both the time of the blood test and this behaviour must be considered before changing the prescribed dose of lithium salt because of a laboratory result. A lithium tolerance curve may be a safer guide to treatment than single measures. Mild intermittent thirst is a common early side effect, and severe persistent thirst with polyuria is an uncommon later effect of daily intakes of at least 1,500 mg lithium carbonate. This diabetes insipidus is reversible, non-progressive, unrelated to plasma level, and distinct in attack from lithium-induced hypothyroidism, which may occur at low dosage but is also usually of late onset and reversible or treatable with thyroxine while lithium is continued. Obesity is another occasional effect of large doses. These side effects and the antimanic and prophylactic effects may have different mechanisms. PMID:4425791

The antipsychotic drug molindone is considered to be atypical in its mode of action and to have mild side effects. Currently no data are available on the range of serum levels of this drug during treatment. By means of a high performance liquid chromatographic technique, serum molindone levels were measured in 14 psychotic patients receiving a wide range of doses of this drug. Molindone levels as high as 350 ng/mL were obtained and were not associated with any toxic effects. Significant relations were noted between the serum level of the drug and both serum prolactin level and treatment response. The authors suggest that molindone may have a range of serum levels consistent with therapeutic benefit. Serum molindone and prolactin levels might help assess resistance to molindone treatment.

1985-01-01

Passive dark avoidance conditioning and effects of the presence and absence of a fish-like dummy on the training process were studied in four inbred strains of paradise fish. Strain differences were found in the shuttle activity during habituation trials, and in the sensitivity to the mild electric shock punishment. The presence or absence of the dummy in the punished dark side of the shuttle box had a genotype-dependent effect on the measures taken during the conditioning process. The statistical analysis of the learning curves revealed differences in the way the strains varied in the different environments, i.e. genotype--environment interaction components of variances were identified. The results are discussed in the light of previous investigations and their implication in further genetic analysis.

Budesonide foam is used for the topical treatment of distal ulcerative colitis. This phase III study was performed to confirm mucosal healing and other therapeutic effects of twice-daily budesonide 2-mg foam in patients with mild-to-moderate ulcerative colitis including left-sided colitis and pancolitis. This was a multicenter, randomized, placebo-controlled, double-blind trial. A total of 126 patients with mild-to-moderate ulcerative colitis with active inflammation in the distal colon were randomized to two groups receiving twice-daily budesonide 2 mg/25 ml foam or placebo foam. The primary endpoint was the percentage of complete mucosal healing of distal lesions (endoscopic subscore of 0) at week 6. Some patients continued the treatment through week 12. Drug efficacy and safety were evaluated. The percentages of both complete mucosal healing of distal lesions and clinical remission were significantly improved in the budesonide as compared with the placebo group (p = 0.0003 and p = 0.0035). Subgroup analysis showed similar efficacy of budesonide foam for complete mucosal healing of distal lesions and clinical remission regardless of disease type. The clinical remission percentage tended to be higher in patients achieving complete mucosal healing of distal lesions than in other patients. There were no safety concerns with budesonide foam. This study confirmed for the first time complete mucosal healing with twice-daily budesonide 2-mg foam in mild-to-moderate ulcerative colitis with distal active inflammation. The results also indicated that complete mucosal healing of distal lesions by budesonide foam promotes clinical remission of ulcerative colitis. Clinical trial registration no.: Japic CTI-142704.

N-methyl-D-aspartate receptor (NMDAR)-mediated neurotransmission is vital for learning and memory. Hypofunction of NMDAR has been reported to play a role in the pathophysiology of Alzheimer disease (AD), particularly in the early phase. Enhancing NMDAR activation might be a novel treatment approach. One of the methods to enhance NMDAR activity is to raise the levels of NMDA coagonists by blocking their metabolism. This study examined the efficacy and safety of sodium benzoate, a D-amino acid oxidase inhibitor, for the treatment of amnestic mild cognitive impairment and mild AD. We conducted a randomized, double-blind, placebo-controlled trial in four major medical centers in Taiwan. Sixty patients with amnestic mild cognitive impairment or mild AD were treated with 250-750 mg/day of sodium benzoate or placebo for 24 weeks. Alzheimer's Disease Assessment Scale-cognitive subscale (the primary outcome) and global function (assessed by Clinician Interview Based Impression of Change plus Caregiver Input) were measured every 8 weeks. Additional cognition composite was measured at baseline and endpoint. Sodium benzoate produced a better improvement than placebo in Alzheimer's Disease Assessment Scale-cognitive subscale (p = .0021, .0116, and .0031 at week 16, week 24, and endpoint, respectively), additional cognition composite (p = .007 at endpoint) and Clinician Interview Based Impression of Change plus Caregiver Input (p = .015, .016, and .012 at week 16, week 24, and endpoint, respectively). Sodium benzoate was well-tolerated without evident side-effects. Sodium benzoate substantially improved cognitive and overall functions in patients with early-phase AD. The preliminary results show promise for D-amino acid oxidase inhibition as a novel approach for early dementing processes. Copyright © 2014 Society of Biological Psychiatry.

The use of mechanical/physical devices for applying mild therapeutic hypothermia is the only proven neuroprotective treatment for survivors of out of hospital cardiac arrest. However, this type of therapy is cumbersome and associated with several side-effects. We investigated the feasibility of using a transient receptor potential vanilloid type 1 (TRPV1) agonist for obtaining drug-induced sustainable mild hypothermia. First, we screened a heterogeneous group of TRPV1 agonists and secondly we tested the hypothermic properties of a selected candidate by dose-response studies. Finally we tested the hypothermic properties in a large animal. The screening was in conscious rats, the dose-response experiments in conscious rats and in cynomologus monkeys, and the finally we tested the hypothermic properties in conscious young cattle (calves with a body weight as an adult human). The investigated TRPV1 agonists were administered by continuous intravenous infusion. Screening: Dihydrocapsaicin (DHC), a component of chili pepper, displayed a desirable hypothermic profile with regards to the duration, depth and control in conscious rats. Dose-response experiments: In both rats and cynomologus monkeys DHC caused a dose-dependent and immediate decrease in body temperature. Thus in rats, infusion of DHC at doses of 0.125, 0.25, 0.50, and 0.75 mg/kg/h caused a maximal ΔT (°C) as compared to vehicle control of -0.9, -1.5, -2.0, and -4.2 within approximately 1 hour until the 6 hour infusion was stopped. Finally, in calves the intravenous infusion of DHC was able to maintain mild hypothermia with ΔT > -3°C for more than 12 hours. Our data support the hypothesis that infusion of dihydrocapsaicin is a candidate for testing as a primary or adjunct method of inducing and maintaining therapeutic hypothermia.

Rationale In obstructive sleep apnea patients (OSA), continuous positive airway pressure (CPAP) adherence is crucial to improve symptoms and cardiometabolic outcomes. The choice of mask may influence CPAP adherence but this issue has never been addressed properly. Objective To evaluate the impact of nasal pillows, nasal and oronasal masks on CPAP adherence in a cohort of OSA. Methods Newly CPAP treated OSA participating in “Observatoire Sommeil de la Fédération de Pneumologie”, a French national prospective cohort, were included between March 2009 and December 2011. Anthropometric data, medical history, OSA severity, sleepiness, depressive status, treatment modalities (auto-CPAP versus fixed pressure, pressure level, interface type, use of humidifiers) and CPAP-related side effects were included in multivariate analysis to determine independent variables associated with CPAP adherence. Results 2311 OSA (age = 57(12) years, apnea+hypopnea index = 41(21)/h, 29% female) were included. Nasal masks, oronasal masks and nasal pillows were used by 62.4, 26.2 and 11.4% of the patients, respectively. In univariate analysis, oronasal masks and nasal pillows were associated with higher risk of CPAP non-adherence. CPAP non-adherence was also associated with younger age, female gender, mild OSA, gastroesophageal reflux, depression status, low effective pressure and CPAP-related side effects. In multivariate analysis, CPAP non-adherence was associated with the use of oronasal masks (OR = 2.0; 95%CI = 1.6; 2.5), depression, low effective pressure, and side effects. Conclusion As oronasal masks negatively impact on CPAP adherence, a nasal mask should be preferred as the first option. Patients on oronasal masks should be carefully followed. PMID:23691209

What is already known about this subject Despite encouraging effects of N-methyl-D-aspartate (NMDA) receptor antagonists in reducing neuropathic pain of different aetiologies, the clinical use of these agents has been limited by their mainly psychotropic side-effects. In a recent study in healthy volunteers, CNS 5161, a novel noncompetetive NMDA receptor antagonist, was well tolerated up to a dosage of 2000 µg without psychotropic side-effects. This is the first study to evaluate the maximal tolerated dosage of CNS 5161 and to gain experience about the analgesic effect of CNS 5161 in patients with different pain syndromes. What this study adds In patients with neuropathic pain CNS 5161 is well tolerated up to a dosage of 500 µg with the most common side-effect of increasing blood pressure, mild visual disturbances and headaches. While no therapeutic effect can be observed in a dosage up to 250 µg, treatment with 500 µg CNS 5161 provides some indications of analgesic activity. It appears that this effect occurs predominantly in patients with diabetic neuropathy. Aims The purpose of the current study was to establish the safety and maximal tolerated dose of CNS 5161 HCl. Methods Forty patients with chronic neuropathic pain (23 male, 17 female) were treated with escalating dosages of CNS 5161. All adverse events to study drug, blood pressure, heart rate, ECG, drug level and clinical laboratory values were monitored. Actual pain was measured on a 100-mm visual analogue scale (VAS) and ordinal verbal pain scores. Results The most commonly occurring nervous system disorder was headache, which was found more often during placebo than during CNS 5161 HCl treatment. Visual disturbances were experienced by 16.7% of patients receiving 250 µg and by 33.3% receiving 500 µg CNS 5161 HCl, but not during placebo treatment. An increase in blood pressure was observed in 8.3% of patients receiving 250 µg and in 50% of patients receiving 500 µg CNS 5161 HCl, compared with 15.4% during placebo treatment. The study was abandoned after two patients entered the 750 µg cohort due to a sustained systolic blood pressure response. Although this study was underpowered for the confirmation of efficacy, some indications of greater pain relief after 500 µg CNS 5161 compared with placebo could be observed (change in VAS between baseline and 12 h 10 ± 22 mm vs. 2 ± 19 mm; P = 0.11). Conclusions CNS 5161 HCl was reasonably well tolerated up to 500 µg. The most common adverse events were hypertension, headache and mild visual disorders. PMID:17391323

Despite their prevalence, there is a paucity of information in the medical literature on the treatment of atrophic chickenpox scars. To evaluate the efficacy and safety of using the chemical reconstruction of skin scar technique for the treatment of atrophic facial chickenpox scars. One hundred patients (mean age 23 years; Fitzpatrick skin types II-IV) were treated with focal chemical peeling with 70% trichloroacetic acid (TCA) for a maximum of six sessions. Improvement rate, frequency of adverse events and patient satisfaction were assessed. Five hundred thirty-three peeling sessions in 100 consecutive patients were performed. Final assessment at 12-week follow-up visit after the last treatment revealed improvement in 95% of patients: mild improvement in 12 cases, moderate improvement in 42 cases, and marked improvement in 41 cases. The appearance of scars did not change in five patients. Seventy-nine patients expressed moderate to high satisfaction with the results. Post-treatment side effects were mild and transient, resolving gradually within the study period. Focal peeling with high-concentration TCA appears to be a safe and effective alternative in the treatment of atrophic facial chickenpox scars. © 2012 by the American Society for Dermatologic Surgery, Inc.

Psoriasis is a relatively common chronic inflammatory skin disease in children for which there is no cure. Most children have mild disease that can be managed with topical therapy as opposed to phototherapy or systemic therapy. Despite the mild presentation of psoriasis in most children, the disease can have a significant impact on quality of life due to the need for ongoing treatment, the frequently visible nature of the cutaneous manifestations, and the social stigma that is associated with psoriasis. Adherence to treatment, in particular topical therapy, is often poor in adults and compromises response to therapy and medical provider management strategies. Multiple factors that may contribute to nonadherence in adults with psoriasis have been identified, including lack of education on the disease and expectations for management, issues related to ease of use and acceptability of topical medications, and anxiety regarding possible medication side effects. There is currently no published data on adherence in the pediatric psoriasis population; however, poor adherence is often suspected when patients fail to respond to appropriate therapy. General strategies used to assess adherence in other pediatric disease populations can be applied to children with psoriasis, and interventions that reflect experience in other chronic dermatologic disorders such as atopic dermatitis may also be helpful for medical providers caring for children with psoriasis.

  The long-term patient satisfaction and safety of nightguard vital bleaching (NGVB) requires further evaluation.   The purpose of this study was to evaluate patients' satisfaction and identify side effects of NGVB up to 17 years post-treatment.   Thirty-one participants who had completed previous NGVB studies using 10% carbamide peroxide were contacted at least 10 years post-treatment (range 10-17 years, average 12.3 years). Participants reported shade satisfaction (very satisfied [VS], partially satisfied [PS], or not satisfied [NS]) as well as potential complications. Participants had teeth # 6 to 11 examined for tooth vitality, gingival inflammation (Löe's Gingival Index [GI]), and radiographically for external cervical resorption (ECR).   All of the participants had successful lightening of their teeth. Sixty-one percent (19) had not retreated their teeth. Of those who had not retreated their teeth and who responded to the question of whitening satisfaction, 31% (4/13) were VS, 54% (7/13) were PS, and 15% (2/13) were NS with their current shade. Of those who had retreated their teeth, all were VS or PS. Ninety-one percent of the examined teeth had GI = 0 (normal), 7% had GI = 1 (mild inflammation), and 2% had GI = 2 (moderate inflammation). Sixty-nine percent of teeth tested responded to a cold stimulus. Radiographs did not detect ECR or apical lesions. No participant reported having a gingival biopsy post-treatment, and 87% would whiten again.   Patient satisfaction with NGVB may last as long as 12.3 years in average (range 10-17 years) post-treatment. GI and ECR findings were considered within the normal expectations for the sample studied, suggesting minimal clinical post-NGVB side effects up to 17 years. Nightguard vital bleaching provides patient satisfaction with minimal side effects up to 17 years post-treatment. © 2011 Wiley Periodicals, Inc.

AIM: To investigate quadruple therapy with rabeprazole, amoxicillin, levofloxacin and furazolidone for the eradication of Helicobacter pylori (H. pylori) infection. METHODS: A total of 147 patients were divided into the experimental treatment group (n = 78) and the standard triple treatment group (n = 69). The experimental treatment group received rabeprazole 20 mg, amoxicillin 1.0 g, levofloxacin 0.2 g and furazolidone 0.1 g, twice daily. The standard triple treatment group received omeprazole 20 mg, amoxicillin 1.0 g and clarithromycin 0.5 g, twice daily. RESULTS: One month after treatment, the 13C urea breath test was carried out to detect H. pylori. The eradication rate using per-protocol analysis was 94.3% in the experimental treatment group and 73% in the standard triple treatment group (P < 0.05), and using intention to test analysis, these figures were 86% and 67% in the two groups, respectively. Side effects were observed in 34 patients, and included mild dizziness, nausea, diarrhea and increased bowel movement. Eleven of the 34 patients needed no treatment for their side effects. CONCLUSION: Rabeprazole, amoxicillin, levofloxacin and furazolidone quadruple therapy is a safe method for the eradication of H. pylori with high efficacy and good tolerability. PMID:23429422

Extrapyramidal side-effects (EPS), the most frequent and severe side-effects of antipsychotics, sometimes become irreversible and cause severe psychosocial disturbance in patients with schizophrenia. However, the neurobiological basis of EPS has not yet been elucidated. In this study, neurochemical correlates of EPS were examined by 1H-MR spectroscopy (1H-MRS). Sixteen medicated patients with schizophrenia and 15 age-, gender- and parental-socioeconomic-status-matched normal controls were examined using single-voxel 1H-MRS. Absolute concentrations of N-acetyl aspartate (NAA), choline-containing compounds (Cho), creatine/phosphocreatine, myo-inositol, and Glx (glutamate and glutamine) in the left putamen were evaluated. The patient group showed mild EPS and no significant metabolic abnormalities in this region. The more severe drug-induced parkinsonism assessed by the Simpson-Angus Scale, however, significantly correlated with the higher Cho concentration and tended to be correlated with the higher NAA concentration in the patient group. These results suggest a potential of 1H-MRS as a non-invasive monitoring method of neurobiological correlates of EPS associated with neuroleptic treatments in patients with schizophrenia.

Data from 37 dogs with nasal carcinomas treated with two or more coarsely fractionated courses of radiation therapy (RT) were retrospectively reviewed. The median radiation dose for the first course of RT was 24 Gray (Gy). All dogs clinically responded, and 11 had complete resolution of signs for a median of 114 days. Dogs were retreated at relapse, with a median dose of 20 Gy, and 26 of 37 dogs (70%) had clinical responses. The second course of RT was initiated at a median of 150 days following completion of the first course. Side effects were mild: four dogs had chronic ocular conditions necessitating medication, one of which required enucleation. Median survival time (ST) from the first dose of RT was 453 days and 180 days from the first dose of the second course of RT. The following factors were examined but were not significant for survival: total RT dose, dose of the first course of RT, complete resolution of clinical signs, use of either chemotherapy or nonsteroidal anti-inflammatory drugs (NSAIDs), and stage (T1/T2 versus T3/T4). Dogs responded well to reirradiation with a subset experiencing chronic ocular side effects.

To compare the intraocular pressure (IOP) lowering efficacy and side effects of latanoprost 0.005% and bimatoprost 0.03% in subjects with chronic primary angle closure glaucoma (PACG). This was an observer-masked randomised crossover study of 60 PACG subjects who received either latanoprost or bimatoprost for 6 weeks, after which they were crossed over to the other medication for another 6 weeks. The IOP-reducing effect of the medications was assessed by the reduction in IOP after 6 weeks of treatment compared with baseline. Fifty-four subjects (80 eyes) completed the study. Latanoprost reduced IOP (mean (SD)) by 8.4 (3.8) mm Hg and bimatoprost by 8.9 (3.9) mm Hg from a baseline of 25.2 (3.6) mm Hg and 25.2 (3.6) mm Hg respectively (p = 0.23). Adverse events were mild in both groups; however there were twice as many reports of an adverse event in the bimatoprost group (81%) compared with the latanoprost group (40%, p<0.01). Ocular irritation was the most frequently reported adverse event in both groups; 22 subjects (37.9%) treated with bimatoprost experienced ocular hyperaemia as compared with 13 subjects (22.4%) treated with latanoprost (p = 0.11). Bimatoprost once daily was similarly effective in reducing IOP compared with latanoprost once daily in subjects with chronic PACG. Both drugs were well tolerated with mild ocular adverse events.

The treatment of acne vulgaris poses a challenge to the dermatologist, and the disease causes emotional anxiety for the patient. The treatment of acne vulgaris may be well-suited to home-use applications, where sufferers may be too embarrassed to seek medical treatment. This randomized controlled study is designed to quantify the effectiveness of using a blue light device in a therapy combined with proprietary creams, in the investigation of a self-treatment regimen. A total of 41 adults with mild-to-moderate facial inflammatory acne were recruited. The subjects were randomly assigned to combination blue light therapy (n = 26) or control (n = 15). Photography was used for qualitative assessment of lesion counts, at weeks 1, 2, 4, 8, and 12. All subjects in the treatment cohort achieved a reduction in their inflammatory lesion counts after 12 weeks. The mean inflammatory lesion counts reduced by 50.02% in the treatment cohort, and increased by 2.45% in the control cohort. The reduction in inflammatory lesions was typically observable at week-3, and maximal between weeks 8 and 12. The treatment is free of pain and side-effects. The blue light device offers a valuable alternative to antibiotics and potentially irritating topical treatments. Blue light phototherapy, using a narrow-band LED light source, appears to be a safe and effective additional therapy for mild to moderate acne.

The purpose of the experiment was to assess the effect of binasal occlusion (BNO) on the visually-evoked potential (VEP) in visually-normal (VN) individuals and in those with mild traumatic brain injury (mTBI) for whom BNO frequently reduces their primary symptoms related to abnormally-increased visual motion sensitivity (VMS). Subjects were comprised of asymptomatic VN adults (n = 10) and individuals with mTBI (n = 10) having the symptom of VMS. Conventional full-field VEP testing was employed under two conditions: without BNO and with opaque BNO which blocked regions on either side of the VEP test stimulus. Subjective impressions were also assessed. In VN, the mean VEP amplitude decreased significantly with BNO in all subjects. In contrast, in mTBI, the mean VEP amplitude increased significantly with BNO in all subjects. Latency was normal and unaffected in all cases. Repeat VEP testing in three subjects from each group revealed similar test-re-test findings. Visuomotor activities improved, with reduced symptoms, with BNO in the mTBI group. It is speculated that individuals with mTBI habitually attempt to suppress visual information in the near retinal periphery to reduce their abnormal VMS, with addition of the BNO negating the suppressive influence and thus producing a widespread disinhibition effect and resultant increase in VEP amplitude.

Hyperpolarized 129 Xe is a promising contrast agent for MRI of pediatric lung function, but its safety and tolerability in children have not been rigorously assessed. To assess the feasibility, safety and tolerability of hyperpolarized 129 Xe gas as an inhaled contrast agent for pediatric pulmonary MRI in healthy control subjects and in children with cystic fibrosis. Seventeen healthy control subjects (ages 6-15 years, 11 boys) and 11 children with cystic fibrosis (ages 8-16 years, 4 boys) underwent 129 Xe MRI, receiving up to three doses of 129 Xe gas prepared by either a commercially available or a homebuilt 129 Xe polarizer. Subject heart rate and SpO 2 were monitored for 2 min post inhalation and compared to resting baseline values. Adverse events were reported via follow-up phone call at days 1 and 30 (range ±7 days) post-MRI. All children tolerated multiple doses of 129 Xe, and no children withdrew from the study. Relative to baseline, most children who received a full dose of gas for imaging (10 of 12 controls and 8 of 11 children with cystic fibrosis) experienced a nadir in SpO 2 (mean -6.0 ± standard deviation 7.2%, P≤0.001); however within 2 min post inhalation SpO 2 values showed no significant difference from baseline (P=0.11). There was a slight elevation in heart rate (mean +6.6 ± 13.9 beats per minute [bpm], P=0.021), which returned from baseline within 2 min post inhalation (P=0.35). Brief side effects related to the anesthetic properties of xenon were mild and quickly resolved without intervention. No serious or severe adverse events were observed; in total, four minor adverse events (14.3%) were reported following 129 Xe MRI, but all were deemed unrelated to the study. The feasibility, safety and tolerability of 129 Xe MRI has been assessed in a small group of children as young as 6 years. SpO 2 changes were consistent with the expected physiological effects of a short anoxic breath-hold, and other mild side effects were consistent with the known anesthetic properties of xenon and with previous safety assessments of 129 Xe MRI in adults. Hyperpolarized 129 Xe is a safe and well-tolerated inhaled contrast agent for pulmonary MR imaging in healthy children and in children with cystic fibrosis who have mild to moderate lung disease.

Medical therapies have been widely used for premenstrual syndrome (PMS), but in all of them side effects are predominant. Herbal remedies rarely have side effects and people have more tendencies toward them than chemical therapies. In this study the therapeutic effect of Vitex agnus castus on women who had the PMS, in comparison with placebo, were investigated. In this randomized, placebo-controlled, double-blind study, from 134 selected patients 128 women suffered from PMS were evaluated (active 62, placebo 66). All patients answered to a self assessment questionnaire about their headache, anger, irritability, depression, breast fullness and bloating and tympani during the premenstrual period before the study. Forty drops of Vitex agnus extract or matching placebo, administrated for 6 days before menses for 6 consecutive cycles. Patients answered the self-assessment questionnaires after 6 menstrual cycles, again. Each item rated using a visual analogue scale (VAS). The mean age was 30.77 (SD=4.37) years in the active group and 30.89 (SD=4.02) years in the placebo group.Rank of variables had significantly difference in active and placebo group before and after the study (P<0.0001) also we noticed significant differences on the use of Vitex agnus in comparison with placebo (P<0.0001). Vitex agnus can be considered as an effective and well tolerated treatment for the relief of symptoms of mild and moderate PMS.

The aim of this study was to evaluate the effect of orlistat or metformin combined with Diane-35 on anthropometric, hormonal and metabolic parameters in overweight and obese polycystic ovary syndrome (PCOS) patients with insulin resistance (fasting insulin > 10 mIU/L). A total of 240 PCOS women were randomly allocated to orlistat plus Diane-35(OD group), metformin plus Diane-35(MD group), orlistat plus metformin plus Diane-35(OMD group) or Diane-35 (D group). Body weight, BMI, waist and hip circumference, blood pressure, endocrine profile, lipid profile and insulin resistance were assessed at baseline and after 3 months. Significant reductions in waist and hip circumference, serum LH, total testosterone and uric acid were observed in all groups compared with baseline. TG and TC significantly decreased in the OD group. Homeostasis model assessment insulin resistance (HOMA-IR) index was reduced in the OD (p = .015), MD (p = .001) and OMD (p = .004) groups. Body weight, BMI, systolic BP and HDL-C significantly changed in the OD and OMD group compared with the D group (p < .05). Side effects were less with orlistat than metformin. This study demonstrated that orlistat is more effective in reducing weight and lipid profile than metformin. Besides, orlistat has mild side-effects and is better tolerated compared with metformin.

In order to investigate the efficacy of bevacizumab on the treatment of radiation cerebral necrosis, patients who were diagnosed with radiation cerebral necrosis by imaging after stereotactic radiotherapy were collected. Bevacizumab was applied at a dose of 5 mg/kg once every three weeks at least three times. The changes in cerebral necrosis symptoms before and after treatment, the cerebral edema volume, the cerebral necrosis volume, and the changes in magnetic resonance imaging (MRI) strengthening phase signals of cerebral necrosis were used as the first observation point. The side effects of bevacizumab were used as the second observation point. Total of 14 radiation cerebral necrosis patients were treated with bevacizumab between June 2011 and February 2013 were collected. There were 12 symptomatic patients, of whom 10 patients (83.3%) had reduced symptoms. The edema index grades of nine patients (64.29%) improved. The cerebral necrosis volumes of 13 patients (92.86%) decreased. The T1 phase signal strengths of the intracranial enhanced MRIs of 12 patients (85.71%) significantly decreased. The clinical side effects of bevacizumab were mild. In conclusion, Preliminary results showed that treatment of radiation cerebral necrosis using bevacizumab was safe and effective. This treatment measure is worthy of further study.

Pain intensity was observed before and after the subcutaneous (s.c.) administration of ketamine hydrochloride (80 micrograms/kg/s.c.) or saline (0.9% NaCl given by the same route) in 17 migraine (M) sufferers as an acute treatment of their M attacks. The same parameter was observed in another group of 17 M-sufferers complaining of very severe and frequent M attacks; these subjects were completely refractory to the prophylactic treatments currently used in M. In this second group, ketamine 80 micrograms/kg/s.c./three times a day) or saline was randomly assigned in a short (3-week) chronic treatment. A randomized, double-blind, cross-over study design was used both when testing ketamine as an acute administration for relieving M attack and when comparing its effect to that of the placebo in a chronic treatment for preventing M-pain. Ketamine, but not placebo, produced a marked relief of pain both as an acute treatment and as a prophylactic therapy. Mild specific side-effects were observed in the majority of the patients treated with ketamine. Moreover in the placebo group, the majority of these patients also complained of side-effects. The present results support the hypothesis that N-methyl-D-aspartic acid (NMDA) receptors play an important role in the mechanisms of M.

The dose, efficacy, and side effects of continuous intravenous infusion (CIVI) of morphine were compared with continuous subcutaneous infusion (CSCI) of morphine in patients with chronic cancer pain. Eligible patients were referred to the Palliative Care Program and were receiving a stable dose of CIVI of morphine. The design was a within-patient, one-way crossover; in which each patient provided data before and after a switch from CIVI to CSCI of morphine. "Rescue" doses were 50% of the hourly dose given every 2 hours as needed. Morphine was infused intravenously (i.v.) and subcutaneously (s.c.) via a McGaw/AccuPro Volumetric Infusion Pump. After baseline data, including side effects and pain assessment, were obtained, patients were evaluated twice daily for toxicity and analgesic efficacy. Those who had a stable CIVI dose for 48 consecutive hr were crossed over to the CSCI at the same dose as the intravenous (i.v.) phase. A stable dose was defined as no dose change, four or less rescue doses in the previous 24 hr, and a pain rating of none or mild. CIVI was considered equal to CSCI if these criteria were maintained for 96 consecutive hr. Fifty-seven patients were entered, and 40 were evaluable (15 women and 25 men). The median age was 67 (range 30-83 years). All 40 participants, after maintaining a stable dose throughout the i.v. phase, crossed to the s.c. phase and remained on s.c. for at least 48 hr. Thirty-two patients maintained a stable dose throughout the i.v. and s.c. phases. The mean stable i.v. dose (day 2) was 5.05 mg/hr, and the mean stable s.c. dose (day 4) was 5.7 mg/hr (P = 0.01). The mean number of rescue doses on day 2 was 0.83 per 24 hr versus 0.80 per 24 hours on day 4 (P = 0.6). The mean categorical pain score on day 2 was 0.83, and on day 4, 0.85 (P = 0.7). The mean visual analogue scale (VAS) on day 2 was 22.9 mm versus 17.6 mm on day 4 (P = 0.1). The mean incidence of side effects on day 2 was 1.7, and on day 4, 2.0 (P = 0.2). No patient was withdrawn or had a dose reduction due to unacceptable toxicity. There were two reports of local toxicity (mild erythema) at the SC needle insertion point, which required a site change. All of our 40 patients had adequate pain control with CIVI and CSCI morphine. Of the eight participants who were not maintained on the same i.v. and s.c. dose, all had adequate pain control and a similar side-effect profile on a higher s.c. morphine dose. These data suggest that the i.v. and s.c. routes are equianalgesic for most patients when administered as a continuous infusion. Pain control and side-effect profiles are quite similar and acceptable. s.c. morphine is an excellent alternative to i.v. morphine in both inpatients and outpatients requiring parenteral morphine for pain.

Photothermal and magnetothermal effects are promising in hyperthermia for cancer therapy. However, the development of safe treatments with limited side-effects requires a relatively-high thermal efficiency triggered by mild near-infrared (NIR) light and alternating magnetic field (HAC), which remains a formidable challenge. In this work, a magnetic field enhanced photothermal effect (MFEP) of Fe3O4 nanoparticles is proposed and investigated systematically. The results suggest remarkable temperature increments of 9.59 to 36.90 °C under irradiation of NIR with different light power densities (808 nm, 0-6.98 W/cm2) combined with a certain magnetic field (HAC = 1.5 kA/m at 90 kHz). The rise of temperature induced by MFEP is substantially larger than the sum of isolated photothermal and magnetothermal effects, which is attributed to the hot-phonon bottleneck effect. The MFEP of Fe3O4 nanoparticles could serve as an effective treatment for cancer therapy in the future.

To study the efficacy of a noninjectable anesthetic gel with a thermosetting agent in the reduction of pain during scaling and root planing (SRP) in untreated chronic periodontitis patients. This study is a randomized, double-masked, split-mouth, placebo-controlled trial. Thirty patients were enrolled who underwent SRP in a split-mouth (right side/left side) manner. Before commencement of SRP, both quadrants on each side were isolated and had a randomized gel (either placebo or test gel) placed in the periodontal pockets for 30 s. The pain was measured using numerical rating scale (NRS) and verbal rating scale (VRS). The median NRS pain score for the patients treated with the anesthetic test gel was 1 (range: 0-4) as opposed to 5 (range: 3-7) in the placebo treated patients. The mean rank of pain score using NRS in test gel was 16.18 as compared to 44.82 in placebo treated sites. Hence, significant reduction in pain was found in test gel as compared to placebo using NRS (P < 0.001). The VRS showed that the majority of patients reported no pain or mild pain with a median of 1 as compared to placebo treated sites with a median of 2 suggestive of moderate pain. The NRS and VRS pain scores showed that the side treated with anesthetic gel was statistically more effective than the placebo in reducing pain during SRP.

Various treatments are currently available for melasma. However, results are often disappointing. 1 To assess the efficacy and safety of combinations of hydroquinone, glycolic acid, and hyaluronic acid in the treatment of melasma after topical application. 2 To evaluate the dermoscopy as a tool in diagnosis and follow-up of melasma treatment. One hundred patients with mild, moderate-to-severe melasma were divided into five groups. Group I (twenty patients were treated with cream formula containing 4% hydroquinone), group II (twenty patients were treated with cream formula containing 4% hydroquinone + 10% glycolic acid), group III (twenty patients were treated with cream formula containing 4% hydroquinone + 0.01% hyaluronic acid), group IV (twenty patients were treated with cream formula containing 4% hydroquinone + 10% glycolic acid + 0.01% hyaluronic acid), and group V (twenty patients were treated with placebo cream). All patients were subjected to dermoscopic examination and digital photographs before and after treatment. The response and side effects were evaluated. Groups I, III, and IV showed highly significant changes in modified Melasma Area and Severity Index (mMASI) score after using the treatment. Group II showed significant change in mMASI score after using the treatment. The side effects were more reported in group II, followed by group IV, followed by group I, followed by group III. There was highly significant difference between the dermoscopic color findings before and after treatment. Vascularization was another dermoscopic finding. A cream formula containing 4% hydroquinone + 10% glycolic acid + 0.01% hyaluronic acid was very effective in treatment of melasma with tolerable side effects. Dermoscope is a valuable noninvasive tool in the diagnosis and follow-up of melasma treatment. © 2015 Wiley Periodicals, Inc.

The hippocampus is injured in both hypoxia–ischemia (HI) and perinatal iron deficiency that are comorbidities in infants of diabetic mothers and intrauterine growth restricted infants. We hypothesized that preexisting perinatal iron deficiency predisposes the hippocampus to greater injury when exposed to a relatively mild HI injury. Iron-sufficient and iron-deficient rats (hematocrit 40% lower and brain iron concentration 55% lower) were subjected to unilateral HI injury of 15, 30, or 45 mins (n = 12 to 13/HI duration) on postnatal day 14. Sixteen metabolite concentrations were measured from an 11 μL volume on the ipsilateral (HI) and contralateral (control) hippocampi 1 week later using in vivo 1H NMR spectroscopy. The concentrations of creatine, glutamate, myo-inositol, and N-acetylaspartate were lower on the control side in the iron-deficient group (P < 0.02, each). Magnetic resonance imaging showed hippocampal injury in the majority of the iron-deficient rats (58% versus 11%, P < 0.0001) with worsening severity with increasing durations of HI (P = 0.0001). Glucose, glutamate, N-acetylaspartate, and taurine concentrations were decreased and glutamine, lactate and myo-inositol concentrations, and glutamate/glutamine ratio were increased on the HI side in the iron-deficient group (P < 0.01, each), mainly in the 30 and 45 mins HI subgroups (P < 0.02, each). These neurochemical changes likely reflect the histochemically detected neuronal injury and reactive astrocytosis in the iron-deficient group and suggest that perinatal iron deficiency predisposes the hippocampus to greater injury from exposure to a relatively mild HI insult.

Few studies have addressed the practice of chiropractic care of children in Europe. No systematic classification of conditions currently exists in chiropractic pediatrics. The objective of this study was to investigate characteristics of clinical chiropractic practice, including the age of pediatric patients, the number of reports of negative side effects (NSEs), the opinions of doctors of chiropractic on treatment options by patient age groups, the conditions seen and the number of treatment sessions delivered by conditions and by patient age. An Internet cross-sectional survey was conducted in 20 European countries with 4109 doctors of chiropractic invited to reply. The 19 national associations belonging to the European Chiropractic Union and the Danish Chiropractic Association were asked to participate. Respondents were asked to self-report characteristics of their practices. Of the 956 (23.3%) participating chiropractors, 921 reported 19821 pediatric patients per month. Children represented 8.1% of chiropractors' total patient load over the last year. A total of 557 (534 mild, 23 moderate, and 0 severe) negative (adverse) side effects were reported for an estimated incidence of 0.23%. On the given treatment statements, chiropractors reported varying agreement and disagreement rates based on patient age. The 8309 answers on conditions were grouped into skeletal (57.0%), neurologic (23.7%), gastrointestinal (12.4%), infection (3.5%), genitourinary (1.5%), immune (1.4%), and miscellaneous conditions (0.5%). The number of treatment sessions delivered varied according to the condition and the patient age. This study showed that European chiropractors are active in the care of pediatric patients. Reported conditions were mainly skeletal and neurologic complaints. In this survey, no severe NSEs were reported, and mild NSEs were infrequent.

Hyaluronic acid fillers are used to improve the appearance of nasolabial folds (NLF). This study aimed to compare the efficacy, safety, and durability of a new hyaluronic acid gel (BioHyalux) versus Restylane for the correction of NLF. This was a multicenter, double-blinded, randomized, controlled, non-inferiority clinical trial involving 88 subjects with moderate to severe NLF. Subjects were randomized to BioHyalux and Restylane on either sides of the NLF. NLF was assessed before and right after injection, and at 1 week, 1, 3, and 6 months. Patients were followed up for 13-15 months to evaluate the durability and long-term safety. A clinically meaningful response was predefined as at least one-point improvement on the Wrinkle Severity Rating Scale, which is a five-point scale. At 6 months, the response rate of BioHyalux was not inferior to that of Restylane (P < 0.05). At the 13-15 months follow-up, the response rate by investigators was 58.0 % on the BioHyalux side versus 63.8 % on the Restylane side. The response rate by subjects showed similar results, which was 56.5 % on the BioHyalux side versus 60.9 % on the Restylane side at 13-15 months. The subjects' Global Aesthetic Improvement Scale (GAIS) showed that most subjects felt improvements on both sides of NLF (P > 0.05) at all time points. At 6 months, 100 % reported improvements on both side; at 13-15 months, 60 % of subjects reported improvements with BioHyalux versus 64 % with Restylane. Adverse events were transient and predominantly mild or moderate in severity including injection site swelling, pain, itching, bruising, and tenderness. BioHyalux had reliable safety and tolerance, and could be an effective injectable filler for correcting NLF.

Cisplatin (CDDP) has received worldwide approval for clinical use in the past decades. However, its development in cancer chemotherapy was overshadowed by severe side effects and drug resistance. Herein, we developed a CDDP drug delivery system with high encapsulation efficiency and near-infrared light stimuli-responsive drug release properties based on the coordination of novel tellurium-containing block polymer (PEG-PUTe-PEG) and CDDP. The nanocarriers made from PEG-PUTe-PEG were loaded with CDDP and indocyanine green (ICG) simultaneously. The coordination chemistry between CDDP and tellurium guaranteed the nanocarrier a high stability in plasma and prolonged circulation time in vivo by reducing possible penetration of water molecule into the nanoparticles. Under the stimuli of a near-infrared laser, an amount of ROS can be generated by irradiation of ICG. The tellurium is easily oxidized by ROS because of the low electronegativity of tellurium. The CDDP could be rapidly released from the nanocarriers along with the oxidation of the tellurium at the tumor sites as the oxidized tellurium will weaken the coordination interaction with CDDP. In addition, the encapsulated ICG played a synergistic antitumor effect through photothermal effect with mild laser irradiation. The integrated strategy achieved higher antitumor efficacy and showed minimal side effects compared with the CDDP alone. Copyright © 2017 Elsevier Ltd. All rights reserved.

The aim of our study was to evaluate the efficacy and safety of topical cantharidin-podophylotoxin-salicylic acid (CPS) treatment of recalcitrant plantar warts (RPW). This study was carried out in a health center in the city of A Coruña (Spain) between January and December 2013. A total of 75 patients completed all the stages of the research process. Information related to treatment with CPS and adverse effects was abstracted from medical records. Of 93 potential patients identified, 75 had at least one follow-up visit or telephone call after treatment and were included in this study. Patients experienced an average of 5.4 visits until complete resolution of their plantar wart occurred, although CPS was not applied at every visit. Fifty-four patients required one application to eliminate the wart and 21 patients required two applications/patient. Seventy-seven percent of patients experienced blistering - an expected therapeutic side effect. All patients experienced some form of an adverse event, the most common being pain (81.3%) and significant blistering (15%). Other side effects were rare (18.7%) and included pruritus, possible mild infection, significant irritation, and bleeding. All patients reported treatment, supporting our results that CPS is a safe and efficacious treatment modality for RPW and should be considered when symptomatic infection necessitates treatment. © 2016 Wiley Periodicals, Inc.

To assess the side effects unrelated to disease activity and the acceptability of combined oral contraceptives (COCs), progestin-only pills (POPs) and copper-releasing intrauterine devices (IUDs) in women with systemic lupus erythematosus (SLE). A randomized clinical trial including 162 women with SLE, assigned to COC (n=54), POP (n=54) or IUD (n=54). Follow-up visits were conducted after 1, 2, 3, 6, 9 and 12 months of treatment to monitor the presence of symptoms, changes in body weight and blood pressure as well as the development of health problems other than those relating to lupus. Reasons for discontinuation and satisfaction with the use of the assigned method were recorded at the end of treatment. Statistical analysis included descriptive statistics, repeated measure analyses and Kaplan-Meier curves. Significantly different discontinuation rates due to any reason [35%, 55%, 29% (p<0.01)] or nonmedical reasons [(11%, 31%, 4% (p<0.05)] were observed among the COC, POP and IUD groups. Nausea was most frequent among COC users, dysmenorrhea among IUD users and acne and hirsutism among POP users. Mean blood pressures remained unchanged. Mild increases in body weight were observed over time in all treatment groups. Most women were satisfied with the use of the assigned contraceptive method. Oral contraceptives and IUD are acceptable birth control methods for patients with lupus, when counseling and specialized health attention are provided; however, the acceptability of POP appears to be inferior. Side effects unrelated to lupus disease activity are not frequent reasons to discontinue the contraceptive methods. This study delves into an area that has not been explored among patients with lupus. Our findings on the associated side effects and reasons for discontinuing COCs, POPs or copper-bearing IUDs may be useful in improving contraceptive counseling for women with lupus. Furthermore, they also heighten our knowledge on the reasons that may preclude the widespread use of effective contraceptives among lupus patients. Copyright © 2014. Published by Elsevier Inc.

Does Prostate Size Predict the Development of Incident Lower Urinary Tract Symptoms in Men with Mild to No Current Symptoms? Results from the REDUCE Trial.

It has been shown that increased prostate size is a risk factor for lower urinary tract symptom (LUTS) progression in men who currently have LUTS presumed due to benign prostatic hyperplasia (BPH). To determine if prostate size is a risk factor for incident LUTS in men with mild to no symptoms. We conducted a post hoc analysis of the REDUCE study, which contained a substantial number of men (n=3090) with mild to no LUTS (International Prostate Symptom Score [IPSS] <8). Our primary outcome was determination of the effect of prostate size on incident LUTS presumed due to BPH defined as two consecutive IPSS values >14, or receiving any medical (α-blockers) or surgical treatment for BPH throughout the study course. To determine the risk of developing incident LUTS, we used univariable and multivariable Cox models, as well as Kaplan-Meier curves and the log-rank test. Among men treated with placebo during the REDUCE study, those with a prostate size of 40.1-80ml had a 67% higher risk (hazard risk 1.67, 95% confidence interval 1.23-2.26, p=0.001) of developing incident LUTS compared to men with a prostate size 40.0ml or smaller. There was no association between prostate size and risk of incident LUTS in men treated with 0.5mg of dutasteride. The post hoc nature of our study design is a potential limitation. Men with mild to no LUTS but increased prostate size are at higher risk of incident LUTS presumed due to BPH. This association was negated by dutasteride treatment. Benign prostatic hyperplasia (BPH) is a very common problem among older men, which often manifests as lower urinary tract symptoms (LUTS), and can lead to potentially serious side effects. In our study we determined that men with mild to no current LUTS but increased prostate size are much more likely to develop LUTS presumed due to BPH in the future. This association was not seen in men treated with dutasteride, a drug approved for treatment of BPH. Our study reveals that men with a prostate size of 40.1-80ml are potential candidates for closer follow-up. Copyright © 2015 European Association of Urology. Published by Elsevier B.V.

Rojí, Rocío; Centeno, Carlos

2017-12-01

To review recent evidence on the efficacy and safety of methylphenidate as a symptomatic treatment of patients with cancer-related fatigue (CRF). Five clinical trials published since 2011 were identified. Two of these concluded that methylphenidate is more efficacious than placebo in providing relief from CRF, but the remaining three showed no difference in favour of methylphenidate. The studies were heterogeneous as per the dosage, scales used for evaluating fatigue and the target group studied. None of the studies detected serious reactions, and only mild and infrequent side-effects of methylphenidate were reported. Three new metanalyses show the slightly superior effect of methylphenidate compared to placebo in CRF. Overall, literature supports the existence of moderate benefit of methylphenidate in CRF, backed up by weak evidence. Future studies should aim at better identifying the profile of patients who would benefit most from this pharmacological intervention.

Maatman, T.J.; Novick, A.C.; Montague, D.K.

Intracavitary irradiation is effective in the treatment of noninvasive papillary transitional cell carcinoma and carcinoma in situ of the bladder. Mortality has not been associated with this form of therapy. The morbidity associated with intracavitary irradiation consists of mild to severe radiation cystitis and we report 2 such cases. One patient is from a series of 65 patients with noninvasive bladder tumors treated with intracavitary irradiation at this clinic since 1965. The second patient had noninvasive bladder tumors and was treated with intracavitary irradiation elsewhere. In both patients severe radiation cystitis subsequently developed, requiring simple cystectomy and urinary diversion. Themore » potential for this serious side effect must be considered when choosing a form of therapy for patients with noninvasive papillary transitional cell carcinoma and carcinoma in situ of the bladder.« less

Degarelix: a novel gonadotropin-releasing hormone blocker for the treatment of prostate cancer.

PubMed

Anderson, John

2009-05-01

Androgen deprivation therapy with gonadotropin releasing-hormone (GnRH) receptor agonists provides the mainstay of endocrine treatment for advanced prostate cancer. Although effective, GnRH agonists induce an initial testosterone surge, which can cause painful and potentially dangerous clinical flare. Degarelix is a novel GnRH receptor blocker that provides immediate, profound and sustained testosterone reduction, without an initial surge. In a Phase III trial, degarelix and leuprolide showed similar long-term efficacy in maintaining testosterone levels of 0.5 ng/ml or less over 1 year, and induced significantly faster testosterone and prostate-specific antigen suppression. Degarelix was well tolerated; the most common side effects were mild/moderate injection-site reactions and hot flashes. Findings to date suggest that degarelix may make an important contribution to the treatment of prostate cancer.

Behavioral countermeasures for motion sickness would be advantageous because of the side effects of antiemetic drugs, but few alternative treatments are available. The objective of this study was to compare the effectiveness of controlling breathing and listening to a music audiotape designed to reduce motion sickness symptoms, on increasing tolerance to motion-induced nausea. Twenty-four healthy subjects were exposed to nauseogenic Coriolis stimulation on a rotating turntable under three conditions: whilst focusing on controlling breathing; listening to a music audiotape; or without intervention (control). The three conditions were performed by each subject according to a replicated factorial design at 1-week intervals at the same time of day. Ratings of motion sickness were obtained every 30 seconds. Once a level of mild nausea was reached subjects commenced controlling breathing or listened to the music audiotape. Motion was stopped after the onset of moderate nausea. Mean (+/- SD) motion exposure time in minutes tolerated before the onset of moderate nausea was significantly longer (p <.01) for controlling breathing (10.7 +/- 5.6 min) and longer (p <.01) for music (10.4 +/- 5.6 min) compared with control (9.2 +/- 5.9 min). Both controlling breathing and the music audiotape provided significant protection against motion sickness and with similar effectiveness. These nonpharmacologic countermeasures are only half as effective as standard doses of anti-motion sickness drugs, such as oral scopolamine; however, they are easy to implement and free of side effects.

To perform a comparison to determine which of two methods of partial urethral ligation produces the most consistent outcome and fewest side effects. Such a study has not been previously reported. Partial urethral ligation is a means of causing reproducible bladder outlet obstruction. In the male rat model, partial urethral obstruction can be performed either by perineal incision and bulbous urethral ligation or retropubic incision and midprostatic obstruction. Fifteen male Sprague-Dawley rats were studied. Five were selected for bulbous urethral obstruction through a perineal incision, five for midprostatic obstruction using a retropubic approach, and five for a sham operation through a perineal incision. The operative time was shorter and morbidity lower with the perineal approach compared with the retropubic approach. Inflammation or infection, or both, were seen in the prostate, bladder, proximal urethra, ureters, and kidneys in the rats in which a midprostatic obstruction was performed. The proximal urethra and prostate were mildly inflamed in those rats that underwent bulbous obstruction. Sham-operated rats exhibited mild prostatitis only. The perineal approach to the bulbous urethra is the method of choice for creating a partial urethral obstruction model of bladder outlet obstruction in the male rat.

Molecular Mobility in Phase Segregated Bottlebrush Block Copolymer Melts

We investigate the linear viscoelastic behavior of poly(styrene)-block-poly(ethylene oxide) (PS-b-PEO) brush block copolymer (BBCP) materials over a range of vol. fractions and with side chain lengths below the entanglement molecular weights. The high chain mobility of the brush architecture results in rapid micro-phase segregation of the brush copolymer segments, which occurs during thermal annealing at mild temperatures. Master curves of the dynamic moduli were obtained by time-temperature superposition. The reduced degree of chain entanglements leads to a unique liquid-like rheology similar to that of bottlebrush homopolymers, even in the phase segregated state. We also explore the alignment of phase segregated domains at exceptionally low strain amplitudes (γ = 0.01) and mild processing temperatures using small angle X-ray scattering (SAXS). Domain orientation occurred readily at strains within the linear viscoelastic regime without noticeable effect on the moduli. This interplay of high molecular mobility and rapid phase segregation that are exhibited simultaneously in BBCPs is in contrast to the behavior of conventional linear block copolymer (LBCP) analogs and opens up new possibilities for processing BBCP materials for a wide range of nanotechnology applications.

All twelve Beagle dogs undergoing long-term therapy (26 weeks) with the immunosuppressive drug cyclosporine-A (30 mg/kg), developed cutaneous papillomatous hyperplasia. By week 7 all dogs developed generalized lesions distributed over the entire body. These occurred as irregular, oval, sessile, unpigmented, firm masses. The incidence and severity of the skin lesions varied among dogs and anatomic site, with no correlation to the blood level of cyclosporine. Microscopic analysis revealed that the epidermis formed short papillary folds on broad fibrovascular stalks and was hyperkeratotic and acanthotic. Mild hyperplasia of hair follicles and sebaceous glands was also evident. A mild diffuse infiltrate of lymphocytes and plasma cells was present in the papillary dermis. No histopathologic changes typical of papillomavirus infection were identified, nor were papillomavirus group-specific antigens or viral DNA detected. Other cutaneous side effects included hyperkeratosis of footpads, increased growth of hair and nails, and hyperkeratinization of the haired skin of the prepuce. All cutaneous lesions regressed spontaneously within 8 weeks following termination of cyclosporine administration. The hyperplastic lesions may have resulted from the action of cyclosporine via the T-lymphocyte system. Conversely a direct action of this drug on epithelial cells may have stimulated proliferation and keratinization.

Curcuma extract exerts a myorelaxant effect on the mouse intestine. In view of a possible use of curcuma extract in motor functional disorders of the gastrointestinal tract, a safety profile study has been carried out in the mouse. Thirty mice were used to study the in vitro effect of curcuma on gallbladder, bladder, aorta and trachea smooth muscular layers and hearth inotropic and chronotropic activity. The myorelaxant effect on the intestine was also thoroughly investigated. Moreover, curcuma extract (200 mg/Kg/day) was orally administered to twenty mice over 28 days and serum liver and lipids parameters were evaluated. Serum, bile and liver bile acids qualitative and quantitative composition was were also studied. In the intestine, curcuma extract appeared as a not competitive inhibitor through cholinergic, histaminergic and serotoninergic receptors and showed spasmolytic effect on K(+) induced contraction at the level of L type calcium channels. No side effect was observed on bladder, aorta, trachea and heart when we used a dose that is effective on the intestine. An increase in gallbladder tone and contraction was observed. Serum liver and lipids parameters were normal, while a slight increase in serum and liver bile acids concentration and a decrease in bile were observed. Although these data are consistent with the safety of curcuma extract as far as its effect on the smooth muscular layers of different organs and on the heart, the mild cholestatic effect observed in absence of alteration of liver function tests must be further evaluated and the effective dose with minimal side effects considered.

The side effects of conventional non‐steroidal anti‐inflammatory drugs (NSAIDs) on the stomach is undoubtedly a serious public health problem contributing significantly to the morbidity and mortality of patients receiving these drugs. However, the damage of NSAIDs is not confined to the stomach. Indeed the short term and long term damage of NSAIDs on the small bowel (NSAID enteropathy) is more frequent than NSAID gastropathy. Furthermore, NSAID enteropathy is associated with complications (bleeding and protein loss). While many of these are mild, the serious events (significant bleeding, perforation, obstruction, and sudden death) are frequent as that reported for NSAID gastropathy. The diagnosis of NSAID enteropathy has been greatly aided by the introduction of wireless capsule enteroscopy. PMID:16517800

This article reports on two cases of severe pediatric Graves orbitopathy (GO) in two adolescents of African origin. Two black male adolescents presented with highly active GO and signs of beginning compressive optic neuropathy. Neither of them were smokers nor had a family history of GO. Besides urgent referral to pediatric endocrinologists, intravenous methylprednisolon pulse therapy was initiated. In spite of the fluctuating thyroid hormone levels in the initial phase of antithyroid therapy, intravenous steroid administration stopped the progression of malignant GO rapidly in both of our patients without any considerable side effects. Although the course of GO during childhood is considered to be mild, severe, sight threatening GO-requiring immunosuppression-may occur at young age, as in the reported adolescent patients of African descent.

Dexamethasone-induced catatonia in a patient with multiple myeloma.

Vanstechelman, Sylvie; Vantilborgh, Anna; Lemmens, Gilbert

2016-12-01

Catatonia is a complex neuropsychiatric syndrome, caused by different underlying metabolic, neurologic, psychiatric and toxic conditions. Although catatonia is often associated with psychiatric disorders such as schizophrenia or depression, in about 20 to 39% of the patients a somatic illness is found. Unfortunately, this diagnosis is often missed although catatonia is characterized by a specific symptom complex. We report a case of acute catatonia with psychotic features in a patient with multiple myeloma (MM), caused by systemic use of dexamethasone. Physicians should be aware of possible psychiatric side effects when prescribing high doses of dexamethasone. Further, MM patients on corticosteroids should be closely monitored for mild psychological and/or psychiatric symptoms since they may be predictive for the onset of catatonia.

Melatonin is commonly recommended to treat sleep problems in children with developmental disabilities. However, relatively few studies document the efficacy and safety of melatonin in pediatric populations with developmental diagnoses. This chapter reviews recent studies of melatonin efficacy across a wide breadth of developmental disabilities. Overall, short treatment trials (1 week to 3 months) of melatonin were associated with a significant decrease in sleep onset latency time for each of the disorders reviewed, with one notable exception, tuberous sclerosis. In general, reported side effects were uncommon and mild in nature. Across disorders, additional research is needed to draw disability-specific conclusions. However, studies to date provide positive support for future trials that include larger groups of children with specific disabilities/syndromes. PMID:26055866

The aim of this study was to evaluate the feasibility, efficacy and safety of transcatheter closure of patent ductus arteriosus (PDA) with the Occlutech duct occluder (ODO) in children. We reviewed the clinical records of 71 patients who underwent percutaneous closure of PDA with an ODO between September 2014 and August 2016. The Occlutech duct occluder was applied to 71 patients during the study period (September 2014-August 2016), and the results were analyzed in this study. Forty-two of the patients were female and 29 male. The median age was 20.5 months (range, 6-194 months) and median weight was 16 kg (range, 6-68 kg). The PDA was classified as type A in 54 patients (76.1%), type E in 14 (19.7%), type C in 2 (2.8%) and type B in 1 (1.4%) based on the Krichenko classification. A standard ODO device was used for the transcatheter closure procedure in 66 patients and the long-shank ODO device in 5. In the echocardiographic measurement of PDA, the median smallest diameter was 2.7 mm (range, 1.5-7.0 mm), and in the angiographic measurement, the median smallest diameter was 2.5 mm (range, 1.5-6.5 mm). All 71 patients underwent successful PDA closure with the ODO. Angiography following the procedure showed complete closure in 47 patients (66.2%), mild residual shunt in 13 patients (18.3%) and a trivial shunt in 11 patients (15.5%). Color flow Doppler echocardiogpaphy at 24 h post-implantation showed that complete closure was achieved in 65 patients (91.5%), and 6 patients (8.5%) had mild residual shunt. All patients (100%) had complete closure at 30 days of follow-up. The results of this study showed that the Occlutech PDA occluder device is safe and effective in the closure of PDA. As the pulmonary artery side of the device is wider than the aortic side, protrusion toward the aortic side and embolization are prevented, but there is residual shunt in the early period, although this residual shunt disappeared after a few months.

Monophthaloyl diamines derived from naturally occurring amino acids were attached through their free amino functions to resins of the trityl type. The phthaloyl groups were removed by hydrazinolysis, and peptide chains were assembled using Fmoc/tBu-amino acids on the liberated amino functions. The peptidyl aminoalkyl amides obtained were cleaved from the resins by mild acidolysis, with the tBu-side chain protection remaining intact.

The antithyroid drugs mainly include thioimidazole (carbimazole, methimazole=thiamazole) and propylthiouracil. After absorption, carbimazole is rapidly metabolized to methimazole and thus switching between these two drugs should not be considered in case of side effects. Furthermore, in case of side effects, sometimes even cross reactions between thioimidazoles and propylthiouracil occur. Common and typical adverse reactions of antithyroid drugs include dose dependent hypothyroidism and thus thyroid function should be repeatedly checked while the patient is on antithyroid drugs. Furthermore, pruritus and rash may develop. In this case, one might try to switch from thioimidazoles to propylthiouracil or vice versa. Antithyroid drugs may cause mild dose dependent neutropenia or severe allergy-mediated agranulocytosis, which typically occurs during the first three months of treatment, has an incidence of 3 per 10,000 patients and cross reactivity between thioimidazoles to propylthiouracil may occur. Rarely, antithyroid drugs can cause aplastic anemia. Mainly propylthiouracil, but sometimes also methimazole may lead to an asymptomatic transient increase in liver enzymes or to severe, even lethal liver injury of cholestatic or hepatocellular pattern. Since propylthiouracil associated liver injury was observed increasingly among children and adolescent, it has been suggested to prefer thioimidazoles for these patients. Because of these potential serious adverse effects, physicians should advise patients to immediately seek medical help if they get a fever or sore throat or malaise, abdominal complaints or jaundice, respectively. Furthermore, arthralgias may develop in 1-5% of patients under both antithyroid drugs. Since arthralgias may be the first symptom of more serious immunologic side effects, it is recommended to stop the antithyroid drug in this case. Drug induced polyarthritis mainly develops during the first month of therapy, whereas ANCA-positive vasculitis is generally observed only after long term exposure to propylthiouracil or very rarely with the thioimidazoles. The teratogenic risk of the thioimidazoles is somewhat higher (Aplasia cutis congenita), that is why one generally recommends preferring propylthiouracil during pregnancy. During breast feeding both, thioimidazoles or propylthiouracil, may be administered. Nowadays, perchlorate is only used short term in case of latent hyperthyroidism before administering iodine-containing contrast agents. Therefore, the known side effects, which usually are only observed after long term treatment, are not an issue any more.

Coronary heart disease (CHD) is one of the major causes of death and disability in industrialised countries, with elevated blood cholesterol an established risk factor. Total plasma cholesterol reduction in populations suffering from primary hypercholesterolemia may lower CHD incidence. This study investigated the cholesterol reducing capacity of Lactobacillus plantarum ECGC 13110402, a strain selected for its high bile salt hydrolase activity, in 49 normal to mildly hypercholesterolaemic adults. Primary efficacy outcomes included effect on blood lipids (total cholesterol (TC), low density lipoproteins (LDL-C), high density lipoproteins (HDL-C) and triacylgycerides (TAG), inflammatory biomarkers and occurrence/severity of gastrointestinal side effects to establish safety and tolerance of the intervention. Secondary outcomes included blood pressure, immune biomarkers, gut microbiota characterisation and metabonome changes. The study was run in a parallel, double blind, placebo controlled, randomised design in which the active group ingested 2x109 CFU encapsulated Lactobacillus plantarum ECGC 13110402 twice daily. Daily ingestion of the active treatment resulted in a statistically significant reduction in LDL-C in volunteers with baseline TC<5mM during the 0–12 week period (13.9%, P = 0.030), a significant reduction in TC in volunteers with baseline TC≥6mM in the 0–6 week period (37.6%, P = 0.045), a significant decrease in TAG (53.9% P = 0.030) and an increase in HDL-C (14.7%, P = 0.007) in the over 60 years population in the 6–12 week period. A statistically significant reduction in systolic blood pressure was also observed across the active study group in the 6-12-week period (6.6%, P = 0.003). No impact on gastrointestinal function and side effects was observed during the study. Similar to blood and urine metabonomic analyses, faecal metagenomics did not reveal significant changes upon active or placebo intake. The results of this study suggest that Lactobacillus plantarum ECGC 13110402 is a well-tolerated, natural probiotic, that may be used as an alternative or supplement to existing treatments to reduce cardiovascular risk.

The lymph drainage was radically blocked in 29 rabbits. One to three days after the operation Erysipelothrix rhusiopathiae was inoculated subcutaneously into the animals. Some control animals were injected with agents of erysipelas and some only with the sterile solution without additional blockade of the lymph drainage. Light and electron microscopy as well as immuno-histological tests showed that the erysipelas arthritis developing in rabbits closely resembles human rheumatoid arthritis with exsudative-necrotising changes of the synovial membrane, proliferation of synovial cells and subsynovial, perivascular plasmacell, and lymphocyte infiltration. The changes were not intensified by the additional blockade of the lymph drainage, when comparing the side with lymph drainage blockade and the non-operated side. The results may be explained by a marked pathogenetic importance of the erysipelas infection in comparison to the relatively mild, lymphostate dependent alterations as well as by mobilisation of macrophages on the operated side.

Bilateral Pneumothoraces Following Central Venous Cannulation

2009-01-01

We report the occurrence of a bilateral pneumothoraces after unilateral central venous catheterization of the right subclavian vein in a 70-year-old patient. The patient had no history of pulmonary or pleural disease and no history of cardiothoracic surgery. Two days earlier, she had a median laparotomy under general and epidural anaesthesia. Prior to the procedure, the patient was hemodynamically stable and her transcutaneous oxygen saturation was 97% in room air. We punctured the right pleural space before cannulation of the right subclavian vein. After the procedure, the patient slowly became hemodynamically instable with respiratory distress. A chest radiograph revealed a complete left-side pneumothorax and a mild right-side pneumothorax. The right-side pneumothorax became under tension after left chest tube insertion. The symptoms finally resolved after insertion of a right chest tube. After a diagnostic work-up, we suspect a congenital “Buffalo chests” explaining bilateral pneumothoraces and a secondary tension pneumothorax. PMID:19901997

2011-08-01

Introduction. Newer and newer technologies have been widely developed in recent years due to increasing need for aesthetic medicine procedures. Less invasive methods of skin imperfection and time-related lesions removal, IPL (Intense Pulse Light) being one of them, are gaining more and more interest. The shorter the "downtime" for the patient is and the more efficient the procedure results, the more popular the method becomes. Materials and methods_Authors analyse the results of treatment of a 571 patients-group (501 women and 70 men) aged 5-72 years in the period: October 2006-August 2010. IPL™ Quantum (Lumenis Ltd.) device with 560 nm. cut-off filter was used. Results. The results were regarded as: very good, good or satisfying (%):Skin photoaging symptomes 37/40/23, Isolated facial dyschromia 30/55/25, Isolated facial erythema 62/34/4, Lower limbs teleangiectasia 12/36/52, Keratosis solaris on hands 100/-/-. Approximately half of the patients developed transitory erythema and 25%- transitory, mild, circumscribed oedema. Following undesirable effects were noted: skin thermal irritation (6,1% of the patients) and skin hypopigmentation (2% of the patients). Discussion. Results and post-treatment management proposed by authors are similar to those reported by other authors. Conclusions. Treatment results of the 571-patients group prove IPL to be a very efficient method of non-ablative skin rejuvenation. It turned out effective also in lower limbs teleangiectasia treatment. It presents low risk of transitory and mild side effects. Futhermore, with short or no downtime, it is well-tolerated by the patients.

Applications of stated preference discrete choice modelling (SPDCM) in health economics have been used to estimate consumer willingness to pay and to broaden the range of consequences considered in economic evaluation. This paper demonstrates how SPDCM can be used to predict participation rates, using the case of varicella (chickenpox) vaccination. Varicella vaccination may be cost effective compared to other public health programs, but this conclusion is sensitive to the proportion of the target population immunised. A choice experiment was conducted on a sample of Australian parents to predict uptake across a range of hypothetical programs. Immunisation rates would be increased by providing immunisation at no cost, by requiring it for school entry, by increasing immunisation rates in the community and decreasing the incidence of mild and severe side effects. There were two significant interactions; price modified the effect of both support from authorities and severe side effects. Country of birth was the only significant demographic characteristic. Depending on aspects of the immunisation program, the immunisation rates of children with Australian-born parents varied from 9% to 99% while for the children with parents born outside Australia they varied from 40% to 99%. This demonstrates how SPDCM can be used to understand the levels of attributes that will induce a change in the decision to immunise, the modification of the effect of one attribute by another, and subgroups in the population. Such insights can contribute to the optimal design and targeting of health programs. Copyright 2002 John Wiley & Sons, Ltd.

Methylphenidate (MP) is often recommended for symptom control in advanced cancer. Little is known about its side effects in frail adults. To evaluate MP-associated symptoms or side effects (S/E). Data was collected from 2 published prospective cohort series and a phase 2 study of MP for symptom control in advanced cancer. All 3 reports had identical dosing schedules and symptom assessments. Initial MP doses were 10 mg/d (5 mg at 8 AM and at 12 noon) titrated up to a maximum of 30 mg/d. Depression, fatigue, and symptoms identified as possible MP S/E were evaluated for presence (prevalence) and for severity (using categorical scales) before MP (day 0) and on days 3, 5, and 7 thereafter. The categorical scale used was none, mild, moderate, and severe. 62 patients were enrolled. Fifty completed 7 days of MP with a median age of 69 (range 30-90) years. Thirty-five received MP 10 mg/day. Most (96%) had improvement in depression and/or fatigue. Among the 62 patients, new symptom prevalence throughout the study was agitation (16%), insomnia (16%), dry mouth (15%), nausea (10%), tremors (6%), anorexia (5%), headache (3%), palpitations (2%), and vomiting (2%). Patients could have more than 1 symptom simultaneously. Seven (11%) withdrew due to MP S/E. Some symptoms present before MP showed significant improvement during MP therapy. (1) Treatment with MP (10-20 mg/d) in advanced cancer is well tolerated. (2) S/E symptoms with MP appeared to improve spontaneously despite continued MP therapy. (3) Depression and fatigue improved at doses lower than those recommended in other clinical conditions. (4) MP improved depression and fatigue, and some secondary symptoms associated with them. Methylphenidate (MP) appears safe when used in the treatment of depression and fatigue in advanced cancer.

Raster-scanned carbon ion therapy for malignant salivary gland tumors: acute toxicity and initial treatment response

PubMed Central

2011-01-01

Background and purpose To investigate toxicity and efficacy in high-risk malignant salivary gland tumors (MSGT) of the head and neck. Local control in R2-resected adenoid cystic carcinoma was already improved with a combination of IMRT and carbon ion boost at only mild side-effects, hence this treatment was also offered to patients with MSGT and microscopic residual disease (R1) or perineural spread (Pn+). Methods From November 2009, all patients with MSGT treated with carbon ion therapy were evaluated. Acute side effects were scored according to CTCAE v.4.03. Tumor response was assessed according to RECIST where applicable. Results 103 patients were treated from 11/2009 to 03/2011, median follow-up is 6 months. 60 pts received treatment following R2 resections or as definitive radiation, 43 patients received adjuvant radiation for R1 and/or Pn+. 16 patients received carbon ion treatment for re-irradiation. Median total dose was 73.2 GyE (23.9 GyE carbon ions + 49,9 Gy IMRT) for primary treatment and 44.9 GyE carbon ions for re-irradiation. All treatments were completed as planned and generally well tolerated with no > CTC°III toxicity. Rates of CTC°III toxicity (mucositis and dysphagia) were 8.7% with side-effects almost completely resolved at first follow-up. 47 patients showed good treatment responses (CR/PR) according to RECIST. Conclusion Acute toxicity remains low in IMRT with carbon ion boost also in R1-resected patients and patients undergoing re-irradiation. R2-resected patients showed high rates of treatment response, though follow-up is too short to assess long-term disease control. PMID:22046954

Benefit/risk of therapies for rheumatoid arthritis: underestimation of the "side effects" or risks of RA leads to underestimation of the benefit/risk of therapies.

Most physicians are familiar with the side effects or risks of drugs used to treat rheumatoid arthritis (RA), but relatively less familiar with the "side effects" or risks associated with RA itself RA is not thought to have the same potential severity as a cardiovascular or neoplastic disease by most physicians, the public, or even some rheumatologists, although relative rates of predicted mortality in some patients with RA are in the range of some people with coronary artery disease or Hodgkin's disease. Many reasons may be identified to explain why the risks of RA have been underestimated: RA does not lead to acute life-threatening situations; population-based data have suggested that most people who meet criteria for RA have a mild or self-limited process; acute attributed causes of death in people with RA are superficially similar to those in the general population; clinical trials have suggested many therapies that are efficacious over a period of 3-12 months; few long-term longitudinal studies were performed prior to the 1980s; medical recommendations made during the 1950s-1980s suggested that simple therapies were adequate for most patients; and quantitative information concerning patient status is generally not included in standard rheumatology care. As more information has emerged concerning severe long-term outcomes in the "natural history" of RA (as treated prior to the 1990s), new strategies of aggressive intervention have been developed. Furthermore, basic research has led to new therapies. It appears that the benefit/risk ratio of therapies for RA has increased substantially over the last two decades, and the outlook for patients with RA is much better at this time than in previous years.

[Hyponatremia : The water-intolerant patient].

Hensen, J

2012-09-01

Hyponatremia due to intolerance to water is a frequent clinical condition and associated with increased mortality. Besides the well known neurological symptoms, gait disturbances, falls, fractures and osteoporosis have also been described recently in patients with chronic hyponatremia. Acute hyponatremia is a more dramatic situation and needs rapid action when severe neurological symptoms are present. Hypertonic saline is recommended to treat this condition until relief of severe symptoms. The causes of hyponatremia have to be carefully examined. Especially diuretics, antidepressants and endocrine causes, e.g. hypothyroidism, hypocortisolism and hypoaldosteronism should be excluded by examination of the patient history, clinical examination and by laboratory tests. Patients should be classified as being euvolemic, hypovolemic or hypervolemic. Whereas acute hyponatremia with severe symptom should be treated with hypertonic saline, euvolemic hyponatremia due to the syndrome of inappropriate antidiuretic hormone secretion (SIADH) with mild and moderate symptoms can now be treated with tolvaptan, a selective V(2)-vasopressin antagonist. Oral tolvaptan has been shown to be an effective and potent aquaretic to treat hyponatremia caused by SIADH as evidenced by a simultaneous increase in serum sodium and a decrease in urine osmolality. The condition of patients with mild or moderate hyponatremia is also improved. Side effects associated with tolvaptan include increased thirst, dry mouth, polyuria and hypernatremia. Rapid increases in serum sodium should be avoided by close monitoring in a hospital setting.

2012-04-01

The utility of rehabilitative ultrasound imaging (RUSI) for assessing trapezius muscle contractile characteristics was investigated by examining whether muscle thickness changes during contraction (CT) differed between people with and without mild shoulder pain. In 18 subjects with mild shoulder pain (aged 28±8 years) and 18 matched controls, trapezius muscle thickness change was measured in prone at rest at 0° and during isometric CTs at 90° and 120° of shoulder abduction. Images were taken at four sites using a real-time ultrasound scanner (7-MHz linear transducer, 40 mm footprint). Percentage change in muscle thickness from rest was calculated. Differences between painful and non-painful shoulders and participant groups were examined by analysis of variance (ANOVA) and t-tests. There were no significant differences between groups or sides in trapezius muscle thickness change during CT. There was no significant difference in trapezius muscle resting thickness (RT) between painful and non-painful shoulders in the same subjects. Contractile ability of the trapezius muscle, assessed using RUSI was not impaired in subjects with mild shoulder pain during the test manoeuvres used. Further research is warranted involving patients with different severity of symptoms, using other test manoeuvres before RUSI can be advocated for assessing scapular muscle dysfunction.

Efficacy of rivastigmine tartrate, transdermal system, in Alzheimer's disease.

Nieto, Rachel A; Deardorff, William James; Grossberg, George T

2016-01-01

As the most common major neurocognitive disorder, Alzheimer's disease (AD) will play an increasingly important role both socially and financially as the population ages. Approved treatments for AD are symptomatic in nature and show modest improvements in cognition and global functioning among patients with AD. This article focuses on the pharmacokinetics, pharmacodynamics, efficacy, and safety of the transdermal patch form of the cholinesterase inhibitor rivastigmine. The rivastigmine transdermal system is approved for the treatment of patients with mild, moderate, and severe AD. Three randomized trials have shown the rivastigmine patch to be efficacious and tolerable across all stages of AD. The rivastigmine patch offers several advantages over the capsule form, including decreased peak to trough plasma fluctuations, reduced rates of nausea and vomiting, better treatment adherence, higher probability of reaching the target dose, ease of administration, and greater satisfaction among caregivers. These factors may be especially important in patients with severe AD, in which patients are more vulnerable to adverse side effects from higher doses. While the patch is more expensive than generic therapies, patient populations that may benefit from the patch include those that are particularly sensitive to GI side effects, have chronic gastrointestinal problems, have difficulty swallowing medications, or have failed to respond with high doses of other generic options.

L-Dopa in Parkinsonism and the Influence of Previous Thalamotomy

A double-blind cross-over trial over 24 weeks (10 weeks on the active remedy, 4 weeks off treatment, and 10 weeks on placebo) of the effect of L-dopa on idiopathic Parkinsonism (paralysis agitans) has shown no difference in the response obtained in patients who had undergone previous stereotaxic ventrolateral thalamotomy and in those who had not. Of the 34 patients (18 men and 16 women) in the trial 18 had been operated on (nine unilateral, nine bilateral operations) and 16 had not. All patients entering the trial were taking anticholinergic drugs in stable dosage and these were continued throughout. The only factor which seemed to limit the response to treatment was pre-existing hypertension. Of 31 patients who completed the 10-week treatment period, 12 showed marked improvement, 15 moderate improvement, and 4 and mild or negligible change. It seems that previous ventrolateral thalamotomy affords some protection against the development of L-dopa-induced involuntary limb movements on the side contralateral to the operation. As found by others, maximum benefit was seen in bradykinesia and rigidity and related features but a significant reduction in tremor was also noted during treatment. Side effects (nausea, hypotension, and involuntary movements) were common but rarely limited the therapeutic response. PMID:4923653

The identification of infrequent side-effects of clotting factor concentrates, undetected by clinical trials, is facilitated by post-marketing surveillance. We present a post-marketing surveillance study in which 97 patients with haemophilia A, attending three haemophilia centres, were treated over a median follow-up period of 284 days (range 1-1074), and a total follow-up period of 30,080 days, with a pasteurized immunoaffinity purified factor VIII concentrate (Monoclate-P, Armour, Collegeville, USA). 5216 infusions, using 10,527,000 units of Monoclate-P, were carried out, mostly for routine haemarthroses or prophylaxis. No new inhibitors were observed during the study. At the start of the study 60/97 were HIV seropositive, 67/97 HBs antibody positive, 12 HbsAb negative and the remainder HBsAb positive before the study period. 13/14 tested were HAV seropositive at the beginning of the study. One patient became HAV seropositive during the study period, an infection thought to be community acquired. No other seroconversions were observed. Only one mild transfusion reaction was observed. This study confirms the safety and efficacy of Monoclate-P. Post-marketing surveillance or nationally organized pharmaco-vigilance should be practiced more widely to enable identification of low-frequency side-effects of treatment.

Previous studies suggest that efficacy is more important than side-effect risks to psoriasis patients. However, those studies did not consider potentially fatal risks of biologic treatments. To quantify the risks patients are willing to accept for improvements in psoriasis symptoms. Adults with a self-reported physician diagnosis of psoriasis were recruited through the National Psoriasis Foundation. Using a discrete-choice experiment, patients completed a series of nine choice questions, each including a pair of hypothetical treatments. Treatments were defined by severity of plaques, body surface area (BSA), and 10-year risks of tuberculosis, serious infection and lymphoma. For complete clearance of 25% BSA with mild plaques, respondents (n = 1608) were willing to accept a 20% (95% confidence interval: 9-26%) risk of serious infection, 10% (5-15%) risk of tuberculosis and 2% (1-3%) risk of lymphoma. For complete clearance of 25% BSA with severe plaques, respondents were willing to accept a 54% (48-62%) risk of serious infection, 36% (28-49%) risk of tuberculosis and 8% (7-9%) risk of lymphoma. Respondents were asked to evaluate hypothetical scenarios. Actual treatment choices may differ. Respondents were willing to accept risks above likely clinical exposures for improvements in psoriasis symptoms. Individual risk tolerances may vary.

VSL#3 is a probiotic mix preparation reported to be effective in the treatment of mild to moderately active ulcerative colitis. We aimed to perform a systematic review of the literature and a meta-analysis of studies on its efficacy. The searched databases included PubMed, Scopus, and ScienceDirect. The Mantel-Haenszel method was used to pool the effect- ize across studies, and the odds ratios (ORs) and 95% confidence intervals (CIs) of experiencing a specific outcome were calculated. Five studies with 441 patients were identified. The pooled remission rate was 49.4% (95% CI, 42.7-56.1). Only 3 low risk of bias studies with 319 patients met the inclusion criteria for further analysis. A total of 162 patients received 3.6 × 10 CFU/d VSL#3, and 157 patients received placebo. A total of 95% of patients received concomitant therapies with 5-ASA and/or immunomodulators. The Ulcerative Colitis Disease Activity Index was used to define response and remission. A >50% decrease in the Ulcerative Colitis Disease Activity Index was achieved in 44.6% of the VSL#3-treated patients versus 25.1% of the patients given placebo (P = 0008; OR, 2.793; 95% CI, 1.375-5.676; number needed to treat = 4-5). The response rate was 53.4% in VSL#3-treated patients versus 29.3% in patients given placebo (P < 0001; OR, 3.03; 95% CI, 1.89-4.83; number needed to treat = 3-4). The remission rate was 43.8% in VSL#3-treated patients versus 24.8% in patients given placebo (P = 0007; OR, 2.4; 95% CI, 1.48-3.88; number needed to treat = 4-5). No serious side effects were reported. VSL#3, when added to conventional therapy at a daily dose of 3.6 × 10 CFU/d, is safe and more effective than conventional therapy alone in achieving higher response and remission rates in mild to moderately active ulcerative colitis.

2015-07-01

The attendant side effects associated with some synthetic drugs used in the management of diseases have led to the search for safer alternative therapies that are relatively cheaper with minimal side effects. The methanol extract of Calliandra portoricensis root bark (CPRB) was orally administered at the doses of 5, 10, 20, and 25 mg/kg body weight for 14 consecutive days of 5 rats in each group. The control rats were given distilled water. The 95% methanol extract of CPRB significantly (p<0.05) scavenged NO• and OH• radicals compared to vitamin C. The level of lipid peroxidative products (malondialdehyde, MDA) was significantly (p<0.05) attenuated in a dose-dependent manner. Antioxidant enzymes including superoxide dismutase and catalase were significantly (p<0.05) exercabated in both liver and kidney in a dose-dependent manner. Furthermore, serum AST, alanine aminotransaminase and γ-glutamyltransferase (GGT) activity depicted non-significant (p>0.05) increase in the treated animals. The histological examination showed mild vacuolar, portal congestion and cell infiltration by mononuclear of the hepatic tissues. The study then concluded that a therapeutic dose of the methanol extract of CPRB triggered the antioxidant defence systems in male rats. It is, therefore, recommended that the doses should be carefully and clinically chosen because higher doses may cause some health risks.

Topical glucocorticoids (GCs) are the mainstay of treatment for eczema, but GC phobia and fears are very common among the parents of paediatric patients. To survey the nature and extent of "fears" of GC use, and to evaluate if disease severity is associated with such fears. Patients with eczema managed in the paediatric dermatology outpatient clinic of a university hospital were recruited in this survey. Disease severity and various aspects of belief and practices of GC use were assessed with the Nottingham Eczema Severity Score and a questionnaire. GC "fears" were present in two fifths of informants with non-eczematous skin disease and mild eczema, but three fifths in moderate-to-severe disease. Requests for steroid-sparing medications (such as tacrolimus or pimecrolimus) had been made in nearly 50% of cases with moderate-to-severe eczema, and many parents would wait until eczema had worsened or apply GC only as a last resort to avoid potential side effects. "Fears" were predominantly interpersonal and rarely iatrogenic in nature. Skin problems (in particular skin thinning) and adverse effects on growth were the side effects of GC of most concern. However, fewer than half of the informants had discussed their concerns with doctors. Our results suggest the importance of understanding the nature and extent to which GC fears, regardless of eczema severity, are prevalent so that sound advice can be offered in a timely manner to parents and patients.

Feline immunodeficiency virus (FIV), the causative agent of an acquired immunodeficiency syndrome in cats (feline AIDS), is a ubiquitous health threat to the domestic and feral cat population, also triggering disease in wild animals. No registered antiviral compounds are currently available to treat FIV-infected cats. Several human antiviral drugs have been used experimentally in cats, but not without the development of serious adverse effects. Here we report on the treatment of six naturally FIV-infected cats, suffering from moderate to severe disease, with the antiretroviral compound (R)-9-(2-phosphonylmethoxypropyl)-2,6-diaminopurine ([R]-PMPDAP), a close analogue of tenofovir, a widely prescribed anti-HIV drug in human medicine. An improvement in the average Karnofsky score (pretreatment 33.2 ± 9.4%, post-treatment 65±12.3%), some laboratory parameters (ie, serum amyloid A and gammaglobulins) and a decrease of FIV viral load in plasma were noted in most cats. The role of concurrent medication in ameliorating the Karnofsky score, as well as the possible development of haematological side effects, are discussed. Side effects, when noted, appeared mild and reversible upon cessation of treatment. Although strong conclusions cannot be drawn owing to the small number of patients and lack of a placebo-treated control group, the activity of (R)-PMPDAP, as observed here, warrants further investigation. © ISFM and AAFP 2014.

Although immunotherapy is effective in allergic rhinitis, conjunctivitis, asthma and stinging insect hypersensitivity, it carries a risk of anaphylactic reactions. In a 4-year retrospective survey, we investigated 1257 adult patients who had received venom or inhaled-allergen subcutaneous immunotherapy. The dose-increase phase was performed as the 2-day rush protocol for venom immunotherapy and the 6-week protocol for inhaled-allergen immunotherapy. A total of 904 patients received venom immunotherapy and 353 patients inhaled-allergen immunotherapy. The prevalence of systemic reactions was 13.6%. The frequency of systemic reactions was higher during the maintenance phase than in the dose-increase phase (9.6% vs. 5.9%) and was highest in both phases of treatment with honeybee venom (P < 0.001). The majority of systemic reactions were mild. Five (0.4%) patients had reaction with a fall of blood pressure and were treated with adrenaline. There was no fatal outcome. The systemic side-effects during the dose-increase phase of venom immunotherapy occurred at a median dose of 46 microg (range 2-100 microg). Large local reactions occurred in 13.9% of patients without any significant difference between the allergens. We have shown that systemic reactions are not rare even during maintenance phase in patients with a well tolerated dose-increase phase of treatment. The most prominent risk factor for systemic reactions was immunotherapy with honeybee extract.

Background Expensive pharmaceuticals are a major reason for cost intensive health care systems. Long-term immunosuppressive therapy plays a relevant role after organ transplantation. Patents of original drugs have expired and cheaper products are available. Little data are available regarding efficacy and safety of generic immunosuppressive agents. Methods In this prospective study, 25 patients, who were clinically stable for a minimum of 2 years after liver transplantation, were converted from the original formulations of tacrolimus (TAC) and mycophenolate mofetil to the generics Tacpan® (TAP) and Mowel® (MOW). Patients were followed-up for 6 months. Results were compared retrospectively to 25 age- and sex-matched controls treated with the original brands. Results In the matched-pair analysis of TAC trough level/dose ratio, no significant difference was found between TAP/MOW and TAC/mycophenolate mofetil groups. No acute rejection occurred in either group. In total, 17 patients reported mild side effects in the TAP/MOW group. The most common side effects were gastrointestinal symptoms. Intra-individual analysis of costs revealed a considerable cost reduction in the TAP/MOW group (in median 25.03%; P<0.001). Conclusion In summary, the use of the generics TAP/MOW is effective and seems to be safe and cost-efficient in stable liver-transplantation patients. PMID:26604701

Current vitiligo treatments are not always satisfactory for both patients and dermatologists. Recently, combination therapies have been introduced in order to obtain better results and reduce risks in the management of the disease. Novel efficacious products are needed to improve the therapeutic possibilities of dermatologists in the respect of safety for the patients. The objective of the present study was to evaluate the effects of a novel topical in a gel formulation containing phenylalanine, cucumis melo extract, and acetyl cysteine in vitiligo. The present study used an open observational study to evaluate the efficacy and safety of the investigated product, given alone or in combination with 311-nm narrow band microphototherapy. Results were compared with those obtained treating a matched patient population with microphototherapy alone and with clobetasol propionate 0.05% ointment alone. One hundred forty-nine patients suffering from symmetrical vitiligo affecting less than 10% of the skin surface were evaluated. Patients affected by acral vitiligo only were excluded from the analysis. Treatment duration was scheduled for 12 weeks. Excellent repigmentation (>75%) was achieved by 38-73% of patients, depending on the treatment regimen. Mild to moderate side effects were observed only in patients treated with clobetasol 0.05% ointment. The tested gel formulation showed a good efficacy in improving vitiligo repigmentation. No side effects were observed. © 2012 Wiley Periodicals, Inc.

Electroconvulsive therapy (ECT) in schizophrenia: a review of recent literature.

ECT remains an important, yet underutilized, treatment for schizophrenia. Recent research shows that medication-resistant patients with schizophrenia, including those resistant to clozapine, respond well to ECT augmentation. The purpose of this article is to review recent studies of the use of ECT in the treatment of schizophrenia. We performed an electronic database search for articles on ECT and schizophrenia, published in 2017. The main themes of these articles are: epidemiological data on ECT use from various countries; retrospective studies, prospective studies and meta-analyses focusing on efficacy and cognitive side-effects of ECT in schizophrenia; ECT technical parameters and potential biomarkers. There is growing evidence to support the use of ECT for augmentation of antipsychotic response in the treatment of schizophrenia. Cognitive side-effects are generally mild and transient. In fact, many studies show improvement in cognition, possibly related to the improvement in symptoms. There is wide variation among countries in the use of ECT for the treatment of schizophrenia. There are also variations in the choice of ECT electrode placement, parameters and schedules. These technical differences are likely minor and should not interfere with the treatment being offered to patients. Further, long-term studies are needed to optimize ECT treatment parameters, to examine the effect of maintenance ECT and to investigate neuroimaging/biomarkers to understand the mechanism of action and identify potential response predictors to ECT.

This study aimed to ascertain if performance on the Timed Up and Go (TUG) test is associated with indicators of brain volume and cognitive functions among community-dwelling older adults with normal cognition or mild cognitive impairment. Participants were 80 community-dwelling older adults aged 65-89years (44 men, 36 women), including 20 with mild cognitive impairment. Participants completed the TUG and a battery of cognitive assessments, including the Mini-Mental State Examination (MMSE), the Logical Memory I and II (LM-I, LM-II) subtests of the Wechsler Memory Scale-Revised; and the Trail Making Test A and B (TMT-A, TMT-B). Bilateral, right- and left-side medial temporal area atrophy as well as whole gray and white matter indices were determined with the Voxel-based Specific Regional Analysis System for Alzheimer's Disease. We divided participants into three groups based on TUG performance: "better" (≤6.9s); "normal" (7-10s); and "poor" (≥10.1s). Worse TMT-A and TMT-B performance showed significant independent associations with worse TUG performance (P<0.05, P<0.01 for trend, respectively). After adjusting for covariates, severe atrophy of bilateral, right-, and left-side medial temporal areas were significantly independently associated with worse TUG performance (P<0.05 for trend). However, no significant associations were found between MMSE, LM-I, LM-II, whole gray and white matter indices, and TUG performance. Worse TUG performance is related to poor performance on TMT-A and TMT-B, and is independently associated with severe medial temporal area atrophy in community-dwelling older adults.

Introduction: The analgesic effect of low-level laser therapy (LLLT) after mandibular third molar (MTM) extraction is controversial. The aim is to evaluate the effect of intraoral LLLT on postoperative pain after MTMs extraction. Methods: Thirty patients with bilateral symmetrical impacted MTMs underwent surgical extractions. Experimental and control sides were randomly selected to receive LLLT or placebo. Following suturing, a dental assistant applied 810 nm gallium aluminum arsenide (GaAlAs) at three points for 30 s each with a total energy of 9 J. Pain was recorded on a visual analog scale on the 7 successive days. Results: Data analyzed by IBM SPSS Statistics 23 for Windows with P ≤ 0.05 significance level. LLLT appeared to have a high significant effect on pain reduction; however, there was a mild increase in pain after the 4th day. Conclusion: Intraoral 810 nm GaAlAs is effective in reducing postoperative pain when a dose of 32.86 J/cm2 is used. PMID:29264287

The studio di intervento nel decadimento vascolare lieve (IDEALE study) was an open multicenter Italian study, the aim of which was to assess the effectiveness and safety of oral citicoline in elderly people with mild vascular cognitive impairment. The study was performed in 349 patients. The active or citicoline group was composed of 265 patients and included 122 men and 143 women of mean age 79.9 ± 7.8 years selected from six Italian regions. Inclusion criteria were age ≥ 65 years, Mini-Mental State Examination (MMSE) score ≥ 21, subjective memory complaints but no evidence of deficits on MMSE, and evidence of vascular lesions on neuroradiology. Those with probable Alzheimer's disease were excluded. The control group consisted of 84 patients, including 36 men and 48 women of mean age 78.9 ± 7.01 (range 67-90) years. Patients included in the study underwent brain computed tomography or magnetic resonance imaging, and plasma dosage of vitamin B12, folate, and thyroid hormones. Functional dependence was investigated by scores on the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales, mood was assessed by the Geriatric Depression Scale (GDS), and behavioral disorders using the Neuropsychiatric Inventory scale. Comorbidity was assessed using the Cumulative Illness Rating Scale. An assessment was made at baseline (T0), after 3 months (T1), and after 9 months (T2, ie, 6 months after T1). The main outcomes were an improvement in MMSE, ADL, and IADL scores in the study group compared with the control group. Side effects were also investigated. The study group was administered oral citicoline 500 mg twice a day throughout the study. MMSE scores remained unchanged over time (22.4 ± 4 at T0; 22.7 ± 4 at T1; 22.9 ± 4 at T2), whereas a significant difference was found between the study and control groups, both in T1 and in T2. No differences were found in ADL and IADL scores between the two groups. A slight but not statistically significant difference was found in GDS score between the study and control groups (P = 0.06). No adverse events were recorded. In this study, citicoline was effective and well tolerated in patients with mild vascular cognitive impairment. Citicoline activates biosynthesis of phospholipids in neuronal membranes, increases brain metabolism as well as norepinephrine and dopamine levels in the central nervous system, and has neuroprotective effects during hypoxia and ischemia. Therefore, citicoline may be recommended for patients with mild vascular cognitive impairment.

A randomized placebo-controlled trial to evaluate a novel noninjectable anesthetic gel with thermosetting agent during scaling and root planing in chronic periodontitis patients

Aim: To study the efficacy of a noninjectable anesthetic gel with a thermosetting agent in the reduction of pain during scaling and root planing (SRP) in untreated chronic periodontitis patients. Materials and Methods: This study is a randomized, double-masked, split-mouth, placebo-controlled trial. Thirty patients were enrolled who underwent SRP in a split-mouth (right side/left side) manner. Before commencement of SRP, both quadrants on each side were isolated and had a randomized gel (either placebo or test gel) placed in the periodontal pockets for 30 s. The pain was measured using numerical rating scale (NRS) and verbal rating scale (VRS). Results: The median NRS pain score for the patients treated with the anesthetic test gel was 1 (range: 0-4) as opposed to 5 (range: 3-7) in the placebo treated patients. The mean rank of pain score using NRS in test gel was 16.18 as compared to 44.82 in placebo treated sites. Hence, significant reduction in pain was found in test gel as compared to placebo using NRS (P < 0.001). The VRS showed that the majority of patients reported no pain or mild pain with a median of 1 as compared to placebo treated sites with a median of 2 suggestive of moderate pain. Conclusions: The NRS and VRS pain scores showed that the side treated with anesthetic gel was statistically more effective than the placebo in reducing pain during SRP. PMID:27051372

Tympanometric findings in superior semicircular canal dehiscence syndrome.

2013-04-01

The diagnostic role of audio-impedancemetry in superior semicircular canal dehiscence (SSCD) disease is well known. In particular, since the first reports, the presence of evoked acoustic reflexes has represented a determining instrumental exhibit in differential diagnosis with other middle ear pathologies that are responsible for a mild-low frequencies air-bone gap (ABG). Even though high resolution computed tomography (HRCT) completed by parasagittal reformatted images still represents the diagnostic gold standard, several instrumental tests can support a suspect of labyrinthine capsule dehiscence when "suggestive" symptoms occur. Objective and subjective audiometry often represents the starting point of the diagnostic course aimed at investigating the cause responsible for the so-called "intra-labyrinthine conductive hearing loss". The purpose of this study is to evaluate the role of tympanometry, in particular of the inter-aural asymmetry ratio in peak compliance as a function of different mild-low frequencies ABG on the affected side, in the diagnostic work-up in patients with unilateral SSCD. The working hypothesis is that an increase in admittance of the "inner-middle ear" conduction system due to a "third mobile window" could be detected by tympanometry. A retrospective review of the clinical records of 45 patients with unilateral dehiscence selected from a pool of 140 subjects diagnosed with SSCD at our institution from 2003 to 2011 was performed. Values of ABG amplitude on the dehiscent side and tympanometric measurements of both ears were collected for each patient in the study group (n = 45). An asymmetry between tympanometric peak compliance of the involved side and that of the contralateral side was investigated by calculating the inter-aural difference and the asymmetry ratio of compliance at the eardrum. A statistically significant correlation (p = 0.015 by Fisher's test) between an asymmetry ratio ≥ 14% in favour of the pathologic ear and an ABG > 20 dB nHL on the same side was found. When "evocative" symptoms of SSCD associated with important ABG occur, the inter-aural difference in tympanometric peak compliance at the eardrum in favour of the "suspected" side could suggest an intra-labyrinthine origin for the asymmetry. Tympanometry would thus prove to be a useful instrument in clinical-instrumental diagnosis of SSCD in detection of cases associated with alterations of inner ear impedance.

Multiple pregnancies are high risk pregnancies with higher chances of maternal and neonatal mortality and morbidity. In the past decades the number of multiple pregnancies has increased. This trend is partly due to the fact that women start family planning at an increased age, but also due to the increased use of ART.Couples with unexplained or mild male subfertility generally receive intrauterine insemination IUI with controlled hormonal stimulation (IUI COH). The cumulative pregnancy rate is 40%, with a 10% multiple pregnancy rate.This study aims to reveal whether alternative treatments such as IVF elective Single Embryo Transfer (IVF e SET) or Modified Natural Cycle IVF (MNC IVF) can reduce the number of multiple pregnancy rates, but uphold similar pregnancy rates as IUI COH in couples with mild male or unexplained subfertility. Secondly, the aim is to perform a cost effective analyses and assess treatment preference of these couples. We plan a multicentre randomised controlled clinical trial in the Netherlands comparing six cycles of intra-uterine insemination with controlled ovarian hyperstimulation or six cycles of Modified Natural Cycle (MNC) IVF or three cycles with IVF-elective Single Embryo Transfer (eSET) plus cryo-cycles within a time frame of 12 months.Couples with unexplained subfertility or mild male subfertility and a poor prognosis for treatment independent pregnancy will be included. Women with anovulatory cycles, severe endometriosis, double sided tubal pathology or serious endocrine illness will be excluded.Our primary outcome is the birth of a healthy singleton. Secondary outcomes are multiple pregnancy, treatment costs, and patient experiences in each treatment arm. The analysis will be performed according tot the intention to treat principle. We will test for non-inferiority of the three arms with respect to live birth. As we accept a 12.5% loss in pregnancy rate in one of the two IVF arms to prevent multiple pregnancies, we need 200 couples per arm (600 couples in total). Determining the safest and most cost-effective treatment will ensure optimal chances of pregnancy for subfertile couples with substantially diminished perinatal and maternal complications. Should patients find the most cost-effective treatment acceptable or even preferable, this could imply the need for a world wide shift in the primary treatment.

The pulsed-dye laser has been used to treat facial redness and rosacea for decades. Recent advances in dye laser technology enable 50% higher output energies supporting 50% larger treatment areas, and beam-diameters up to 15 mm with clinically-relevant fluences. In this study, we investigate this novel pulsed-dye laser using a 15 mm diameter beam for treatment of rosacea. Twenty subjects with erythemato-telangiectatic rosacea were enrolled in the study. A total of 4 monthly treatments were administered, first treating linear vessels with a 3 × 10 mm elliptical beam, then diffuse redness with a 15-mm diameter circular beam. Blinded assessment of digital, cross-polarized photographs taken 2 months following the last treatment was performed using an 11-point clearance scale. Nineteen subjects completed the study. Blinded reviewers correctly identified baseline photos in 55 out of the total of 57 images (96.5%). The blinded reviewers scored 17 of the 19 subjects with an improvement greater than 40%, and 11 of the 19 subjects greater than 50%. The average improvement was 53.9%. Side effects were limited to mild edema, mild to moderate erythema, and mild to moderate bruising. This study demonstrates that a newly designed pulsed-dye laser having a novel 15-mm diameter treatment beam improves the appearance of rosacea with a favorable safety profile. Lasers Surg.

In 1997, the obligatory model of iodine prophylaxis was introduced in Poland in order to correct the existing status of mild and/or moderate iodine deficiency. In order to monitor possible side-effects of increased iodine supply, studies on iodine-induced hyperthyroidism were initiated by establishing several regional registers of hyperthyroidism. In the present paper, the results of a two-year monitoring (2000-2001) have been summarized. There are no epidemiological data on hyperthyroidism prior to starting the iodine prophylaxis, but the obtained current data are comparable to observations in other countries, made after iodine supplementation. The incidence of iodine-induced hyperthyroidism did not exceed the acceptable level, thus confirming--together with previous observations on the effectiveness of iodine prophylaxis--the adequacy of applied dose of KI (30 microg/kg NaCl), used for salt iodization in Poland.

Methylphenidate (Ritalin) is the only psychostimulant approved in France and indicated in attention deficit hyperactivity disorder in children over 6 years. It is under restricted prescription and distribution conditions. As such, it requires a hospital initiated prescription from either a neurology, psychiatry or pediatric specialist and it is covered by the "narcotics" schedule. The French Pharmacovigilance database spontaneous adverse drug reactions reporting, since it was approved in 1995, were analyzed. 21 adverse drug reactions were reported. In 16 cases, methylphenidate was suspected. They were generally non-serious, mild side effects and in most cases promptly resolved. These results do not suggest methylphenidate misuse in France or an overuse in between 1300 and 4000 treated children, to date. Until more information is available concerning the long-term effects of methylphenidate, and in order to limit misuse, inappropriate or overuse, the current prescription and dispensing regulation should be maintained in France, and could well be developed in other countries.

STI571 (imatinib mesylate; Gleevec) is a selective inhibitor of the bcr-abl, c-kit, and platelet-derived growth factor receptor tyrosine kinases. Mild periorbital edema has been noted as a common side effect in Phase I and II trials of this drug for the treatment of patients with chronic myelogenous leukemia and gastrointestinal stromal tumors. The authors report the case of male patient age 63 years who developed severe periorbital edema after treatment with STI571 for chronic myelogenous leukemia. His edema was severe enough to cause visual obstruction due to lower eyelid festoons that ultimately required surgical debulking. Histopathologic analysis of specimens of the excised upper and lower eyelid tissue revealed dermal dendrocytes that expressed the platelet-derived growth factor receptor and c-kit tyrosine kinases, suggesting a possible role for dermal dendrocytes in the development of this toxic effect.

Osteoarthritis (OA) is the most common debilitating joint disease worldwide. Clinicians have many therapeutic modalities and prescription medications in their arsenals to treat chronic inflammatory pain. However, as patients age, and develop numerous comorbidities, the most common, and often most effective pharmacologic treatment for OA, nonsteroidal anti-inflammatory drugs (NSAIDs), becomes problematic in that it may exacerbate or even cause cardiovascular, renal, and/or gastrointestinal pathology. This paper reviews the metabolism of arachidonic acid as it relates to the clinical treatment of inflammation, and explores a novel botanical therapy, flavocoxid, that has shown equal efficacy to naproxen in treating pain associated with mild to moderate OA of the knee. Flavocoxid has demonstrated balanced inhibition of the three primary enzymes responsible for processing AA, cyclooxygenases 1 and 2, and 5-lipoxygenase. Researchers have proposed that balanced inhibition of AA metabolism offers the promise of analgesia similar to NSAIDs without the associated cardiovascular, renal, or gastrointestinal side effects.

In order to perform refractive surgery, fs-laser pulses of 130-fs pulse duration were focused into animal cornea. By focusing the radiation down to spot-sizes of 5 micrometers , very precise cuts could be achieved inside the treated eyes, accompanied with minimum collateral damage to the tissue by thermal or mechanical effects. Due to these low side effects, micrometers -cutting precisions at preparing of corneal flaps and lenticules can be achieved. Thus, animal studies with 8 living rabbits were performed, in which intrastromal lenticules and flaps were created and extracted. Wound healing reactions were studied by histo- pathological analysis of the treated eyes in intervals at one, 7, 14 and 28 days after surgery. The treated eyes showed mild wound healing reactions with comparable results to what is known from Excimer-LASIK. Moreover the use of the fs-laser offered new possibilities in preparation of corneal flaps, providing advantages to the use of the mechanical keratome.

We in-detail investigated the profile evolution processes of highly ordered alumina under the cyclic treatment of mild anodizing of aluminum foils in oxalic acid followed by etching in phosphoric acid. With the cyclic times increasing, the profiles of nanopores were gradually evolved into the parabola-like, trumpet-like and conical shape. Although the inserted etching itself nearly had no impact on the growth rate of the nanopores due to the rapid recovering of thinned barrier layer at the initial stage of next anodizing, overmuch etching could bring apparent side effects such as wall-breaking, thinning and taper-removing from the top down. The anodizing and etching kinetics and their synergetic effects in modulating different aspect ratios and open sizes of conical pores were studied systematically. These findings are helpful to tailor high-quality anodic alumina taper-pores with tunable profiles.

Crohn's disease (CD) is a chronic inflammatory disorder that commonly affects the terminal ileum and proximal colon. Although systemic corticosteroids such as prednisone and methylprednisolone are widely used for treatment of CD, these agents have a high incidence of adverse drug reactions due to off-target effects. Budesonide is a locally acting corticosteroid with enhanced formulation properties that offer a superior therapeutic index in comparison to conventional members of the class. Areas covered: This review focuses on budesonide for the treatment of CD. The pharmacological and pharmacokinetics of the drug are summarized, along with clinical efficacy and safety data. We also indicate the role of budesonide in therapeutic algorithms. Expert opinion: Budesonide has an important role as an induction therapy in patients with mild to moderately active CD of the ileum and proximal colon. The most distinctive advantage of budesonide over conventional corticosteroids is a substantially reduced risk of corticosteroid-related side effects.

First-line treatment of EGFR-mutant non-small-cell lung cancer: the role of erlotinib and other tyrosine kinase inhibitors

Nguyen, Kim-Son H; Neal, Joel W

2012-01-01

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) were initially established as second- or third-line treatment of advanced non-small-cell lung cancer (NSCLC). Subsequent studies, including IPASS, OPTIMAL, and EURTAC, have demonstrated that these TKIs are effective first-line therapeutic options in patients with tumors harboring activating mutations in the EGFR gene. The TKIs are better tolerated than conventional chemotherapy, with frequent yet mild side effects such as rash and diarrhea, and rarely interstitial lung disease. Because most patients on TKIs develop resistance due to a variety of mechanisms, the use of TKIs in the acquired-resistance setting and in the setting of earlier-staged cancers is being extensively studied. Here we review the major trials leading to the established use of EGFR TKIs in NSCLC, followed by discussion of recently completed and ongoing trials using the next-generation EGFR inhibitor afatinib.

A computational study at the MP2(Full)/6-311++G(d,p)//MP2(Full)/6-31+G(d) level of the ammonolysis of halogen substituted azetidines, oxetanes and thietanes was performed in the gas phase and in the commonly used solvent, acetonitrile. Using the free energy of activation of a benchmark reaction for evaluation of synthetic viability, several haloazetidines and oxetanes that possessed the required reactivity were identified; however, no substituted thietane investigated herein was determined to be synthetically useful under the mild conditions selected for this study. In the case of the azetidines, the side reaction of displacement of halide ion was determined to be the preferred reaction course in acetonitrile; however, the amino product of the reactions of the 2-haloazetidines cleaved at an acceptable rate under mild conditions. For the oxetane derivatives investigated, 2-fluorooxetane proved to be a direct source of ring cleavage product. Nucleophilic cleavage of halogen-substituted azetidines and oxetanes is predicted to be a viable source of functionalized three-carbon moieties under mild conditions in organic synthesis.

A proprietary topical blend of salicylic acid and highly purified sandalwood oil from Australia was used in this open-label study in adolescents and adults with mild to moderate facial acne. The investigational regimen consisted of a foaming cleanser, an acne serum, a spot treatment, and a mask. Patients applied the treatment regimen as directed for 8 weeks. The primary efficacy measure was the percentage of patients assessed as improved, much improved, or very much improved according to the Global Aesthetic Improvement Scale (GAIS) ratings at week 8. Severity was rated using the Evaluator's Global Severity Scores (EGSS) at baseline and weeks 2, 4, and 8. Tolerability was assessed at baseline and weeks 2, 4, and 8 by asking patients to rate the severity of itching, scaling, erythema, burning, dryness, and stinging. Patients were also asked to complete an acne questionnaire. 89.4% (42/47) met the primary end point determined by the GAIS of improved (66%), much improved (19%), or very much improved (4%). Notable reductions in lesion counts were observed in patients with more severe or inflamed lesions. Tolerability was queried at all visits. No itching, scaling, or erythema was reported after initial application. Symptoms of intolerability peaked at week 2; however, most events were mild to moderate and were typically reported with use of the mask component. Intolerance decreased by week 4 and by week 8. The treatment regimen was well tolerated by patients. Results from this study support the use of a proprietary investigational regimen in patients with mild to moderate acne and warrant further investigation to determine whether longer-term therapy (ie, beyond 8 weeks) results in enhanced efficacy with minimal side effects, leading to continued patient compliance and skin improvement.

Soft-tissue augmentation with hyaluronic acid (HA) fillers has become one of the most popular cosmetic procedures performed. HA fillers represent safe and commonly used fillers. Several different HA fillers are available. The differences lie in the manufacturing process, allowing for tailored uses. A small-particle HA with lidocaine (SP-HAL; Restylane Silk; Galderma, Uppsala, Sweden) was approved by the US Food and Drug Administration in June 2014 but has been available for many years in Canada as Restylane Fine Lines and in Europe as Restylane Vital. Relevant articles were reviewed relating to the composition, effectiveness, and safety of SP-HAL. We also discuss the author's extensive clinical experience in the use of this product in Canada. SP-HAL has demonstrated proven benefits for lip fullness, augmentation, and treatment of perioral rhytides. Although off-label in the United States, SP-HAL is also well suited for the treatment of superficial fine lines, including periorbital, forehead, marionette, and smile lines. In addition, it has also been used in the tear trough region. A novel application for SP-HAL includes use as a skinbooster with intradermal micropuncture. In this technique, small aliquots of product are injected so as to gradually rejuvenate the skin in areas such as the face and hands. Side effects of SP-HAL were generally transient and mild. The most common side effects were swelling, tenderness, bruising, pain, and redness. SP-HAL is an effective and safe HA filler with varied clinical uses.

OBJECTIVE Symptoms suggestive of acute bacterial sinusitis are common. Available diagnostic and treatment options generate substantial costs with uncertain benefits. We assessed the cost-effectiveness of alternative management strategies to identify the optimal approach. DESIGN For such patients, we created a Markov model to examine four strategies: 1) no antibiotic treatment; 2) empirical antibiotic treatment; 3) clinical criteria-guided treatment; and 4) radiography-guided treatment. The model simulated a 14-day course of illness, included sinusitis prevalence, antibiotic side effects, sinusitis complications, direct and indirect costs, and symptom severity. Strategies costing less than $50,000 per quality-adjusted life year gained were considered “cost-effective.” MEASUREMENTS AND MAIN RESULTS For mild or moderate disease, basing antibiotic treatment on clinical criteria was cost-effective in clinical settings where sinusitis prevalence is within the range of 15% to 93% or 3% to 63%, respectively. For severe disease, or to prevent sinusitis or antibiotic side effect symptoms, use of clinical criteria was cost-effective in settings with lower prevalence (below 51% or 44%, respectively); empirical antibiotics was cost-effective with higher prevalence. Sinus radiography-guided treatment was never cost-effective for initial treatment. CONCLUSIONS Use of a simple set of clinical criteria to guide treatment is a cost-effective strategy in most clinical settings. Empirical antibiotics are cost-effective in certain settings; however, their use results in many unnecessary prescriptions. If this resulted in increased antibiotic resistance, costs would substantially rise and efficacy would fall. Newer, expensive antibiotics are of limited value. Additional testing is not cost-effective. Further studies are needed to find an accurate, low-cost diagnostic test for acute bacterial sinusitis. PMID:11679039

Gastroenteritis is a common pediatric illness. Electrolyte maintenance solution is recommended to treat and prevent dehydration. Its advantage in minimally dehydrated children is unproven. To determine if oral hydration with dilute apple juice/preferred fluids is noninferior to electrolyte maintenance solution in children with mild gastroenteritis. Randomized, single-blind noninferiority trial conducted between the months of October and April during the years 2010 to 2015 in a tertiary care pediatric emergency department in Toronto, Ontario, Canada. Study participants were children aged 6 to 60 months with gastroenteritis and minimal dehydration. Participants were randomly assigned to receive color-matched half-strength apple juice/preferred fluids (n=323) or apple-flavored electrolyte maintenance solution (n=324). Oral rehydration therapy followed institutional protocols. After discharge, the half-strength apple juice/preferred fluids group was administered fluids as desired; the electrolyte maintenance solution group replaced losses with electrolyte maintenance solution. The primary outcome was a composite of treatment failure defined by any of the following occurring within 7 days of enrollment: intravenous rehydration, hospitalization, subsequent unscheduled physician encounter, protracted symptoms, crossover, and 3% or more weight loss or significant dehydration at in-person follow-up. Secondary outcomes included intravenous rehydration, hospitalization, and frequency of diarrhea and vomiting. The noninferiority margin was defined as a difference between groups of 7.5% for the primary outcome and was assessed with a 1-sided α=.025. If noninferiority was established, a 1-sided test for superiority was conducted. Among 647 randomized children (mean age, 28.3 months; 331 boys [51.1%]; 441 (68.2%) without evidence of dehydration), 644 (99.5%) completed follow-up. Children who were administered dilute apple juice experienced treatment failure less often than those given electrolyte maintenance solution (16.7% vs 25.0%; difference, -8.3%; 97.5% CI, -∞ to -2.0%; P < .001 for inferiority and P = .006 for superiority). Fewer children administered apple juice/preferred fluids received intravenous rehydration (2.5% vs 9.0%; difference, -6.5%; 99% CI, -11.6% to -1.8%). Hospitalization rates and diarrhea and vomiting frequency were not significantly different between groups. Among children with mild gastroenteritis and minimal dehydration, initial oral hydration with dilute apple juice followed by their preferred fluids, compared with electrolyte maintenance solution, resulted in fewer treatment failures. In many high-income countries, the use of dilute apple juice and preferred fluids as desired may be an appropriate alternative to electrolyte maintenance fluids in children with mild gastroenteritis and minimal dehydration. clinicaltrials.gov Identifier: NCT01185054.

Emergency contraception (EC) is a way to significantly reduce the chance of becoming pregnant after an episode of unprotected intercourse. Considerable data support the safety of all available and emerging options for EC. Areas covered: This review presents a comprehensive summary of the literature regarding the safety of EC as well as directions for further study. PubMed was searched for all relevant studies published prior to June 2017. Expertopinion: All available methods of EC (i.e., ulipristal acetate pills, levonorgestrel pills, and the copper-IUD), carry only mild side effects and serious adverse events are essentially unknown. The copper IUD has the highest efficacy of EC methods. Given the excellent safety profiles of mifepristone and the levonorgestrel IUD, research is ongoing related to use of these products for EC.

The debate on treating subclinical hypothyroidism

PubMed Central

Tng, Eng Loon

2016-01-01

Subclinical hypothyroidism (SCH) represents a mild or compensated form of primary hypothyroidism. The diagnosis of SCH is controversial, as its symptoms are non-specific and its biochemical diagnosis is arbitrary. The treatment of SCH was examined among non-pregnant adults, pregnant adults and children. In non-pregnant adults, treatment of SCH may prevent its progression to overt hypothyroidism, reduce the occurrence of coronary heart disease, and improve neuropsychiatric and musculoskeletal symptoms associated with hypothyroidism. These benefits are counteracted by cardiovascular, neuropsychiatric and musculoskeletal side effects. SCH is associated with adverse maternal and fetal outcomes that may improve with treatment. Treating SCH in children is safe and may improve growth. Importantly, the evidence in this field is largely from retrospective and prospective studies with design limitations, which precludes a conclusive recommendation for the treatment of SCH.

Background: Hippocampal volume data from India have recently been reported in younger adults. Data in older adults are unknown. The present paper describes hippocampal volume from India among older adults and compares the same with patients having Alzheimer's disease (AD) and mild cognitive impairment (MCI). Materials and Methods: A total of 32 cognitively normal subjects, 20 patients with AD, and 13 patients with MCI were enrolled. Patients were evaluated for the diagnosis of AD/MCI using the National Institute of Neurological and Communicative Disorders and Stroke and the Related Disorders Association criteria and the Clinical Dementia Rating (CDR) Scale (score = 0.5), respectively. Hippocampal volume was measured using magnetic resonance imaging (MRI) machine by manual segmentation (Megnatom Symphony 1.5T scanner) three-dimensional (3D) sequences. Results: Age and duration of illness in the MCI group were 70.6 ± 8.6 years and 1.9 ± 0.9 years, respectively. In the AD group, age and duration of illness were 72 ± 8.1 years and 3.1 ± 2.2 years, respectively. In cognitively normal subjects, the age range was 45-88 years (66.9 ± 10.32) years. Mean mini–mental status examination (MMSE) score of healthy subjects was 28.28 ± 1.33. In the MCI group, MMSE was 27.05 ± 1.79. In the AD group, MMSE was 13.32 ± 5.6. In the healthy group, the hippocampal volume was 2.73 ± 0.53 cm3 on the left side and 2.77 ± 0.6 cm3 on the right side. Likewise, in MCI, the volume on the left side was 2.35 ± 0.42 cm3 and the volume on the right side was 2.36 ± 0.38 cm3. Similarly, in the AD group, the volume on the right side was 1.64 ± 0.55 cm3 and on the left side it was 1.59 ± 0.55 cm3. Post hoc analysis using Tukey's honestly significant difference (HSD) showed, using analysis of variance (ANOVA) that there was a statistically significant difference between healthy and AD (P ≤ 0.01), and between healthy and MCI (P ≤ 0.01) subjects. There was a correlation between MMSE score and hippocampal volume in the AD group. Conclusion: The volume of the hippocampus in older Indian adults was 2.77 ± 0. 6 cm3 on the right side and 2.73 ± 0.52 cm3 on the left side. There was a significant hippocampal volume loss in MCI/AD compared to cognitively normal subjects. PMID:27293329

Head lice infestation (or pediculosis) is an important public health problem in Thailand, especially in children between the ages 5 and 11 years. Head lice resistance is increasing, chemical pediculicides have lost their efficacy, and, therefore, alternative pediculicides such as herbal shampoos have been proposed to treat head lice infestation. Thus, the present study investigated the efficacy of three herbal shampoos based on native plants in Thailand (Acorus calamus Linn., Phyllanthus emblica Linn., and Zanthoxylum limonella Alston) against head lice and compared them with carbaryl shampoo (Hafif shampoo, 0.6% w/v carbaryl), malathion shampoo (A-Lice shampoo, 1.0% w/v malathion), and commercial shampoos (Babi Mild Natural' N Mild and Johnson's baby shampoo) in order to assess their in vitro and in vivo efficacy. For in vitro study, doses of 0.12 and 0.25 ml/cm(2) of each herbal shampoo were applied to filter paper, then 10 head lice were place on the filter paper. The mortalities of head lice were recorded at 5, 15, 30, and 60 min. The results revealed that all herbal shampoo were more effective on pediculicidal activity than chemical and commercial shampoos with 100% mortality at 15 min; LT₅₀ values ranged from 0.25 to 1.90 min. Meanwhile, chemical shampoos caused 20-80% mortality, and LT₅₀ values ranged from 6.50 to 85.43 min. On the other side, commercial shampoos showed 4.0% mortality. The most effective pediculicide was Z. limonella shampoo, followed by A. calamus shampoo, P. emblica shampoo, carbaryl shampoo, malathion shampoo, and commercial shampoo, respectively. In vivo results showed that all herbal shampoos were also more effective for head lice treatment than chemical and commercial shampoos with 94.67-97.68% of cure rate after the first treatment; the second treatment, 7 days later, revealed that the cure rate was 100%. Meanwhile, chemical shampoo showed 71.67-93.0% of cure rate and, unfortunately, commercial shampoos were nontoxic to head lice and showed 0% of cure rate after the first and the second treatments. Our data showed that three herbal shampoos of native plants in Thailand in this study are suitable to be used as pediculicides for Thai children since it is safe for children and there is no side-effect after application.

Alkylating agents, such as temozolomide (TMZ) and fotemustine (FTM) are widely used in recurrent glioblastoma (GBM) regimes. Several strategies have been proposed to prevent resistance to these agents, by combining or sequencing them. We report the results of a pilot study of patients with refractory GBM receiving a regime of twice-daily dosing of temozolomide administered on day 1, (with an initial oral dose of 200 mg/m(2) and a second oral dose of 75 mg/m(2) 12 h later), followed by fotemustine in a single i.v. infusion at 75 mg/m(2) on day 2, repeated every four weeks. Enrolment was stopped at 15 patients due to lack of effectiveness of this schedule for patients with GBM. Toxicity was mild, with no grade 4 side effects reported. Results indicate that our temozolomide -FTM combined schedule is not effective, although well tolerated, in non responsive patients with GBM. Further strategies are required to improve the outcome of these patients.

The most frequent side effect of topical retinoids is irritant contact dermatitis. It occurs in approximately 85% of patients; the percentage can reach up to 95% in patients treated with tretinoin. Severity of this dermatitis is moderate to severe in approximately 20% of patients. However, 15% of patients stop the treatment with tretinoin because of skin irritation. The authors used tretinoin as short contact therapy (SCT) in mild to moderate acne, in order to try to reduce the incidence and severity of irritant contact dermatitis. They present the final results of a sponsor-free, pilot, open, multicenter study. Seventy-four patients were treated with 0.05% tretinoin cream. It was applied once daily for 30 min. Treatment duration ranged from 8 to 32 weeks (mean duration: 12 weeks). Acne severity and treatment efficacy were evaluated by means of the Global Acne Grading System. A significant clinical improvement (≥50% from baseline) was observed in 41 patients (55.4%). Thirteen patients (17.6%) developed a mild skin irritation. Four patients (5.4%) stopped the treatment because of severe skin irritation. Efficacy of tretinoin used as SCT seems to be superimposable to that of tretinoin used according to standard modality. Tolerability of SCT with tretinoin is very good. This tolerability allows a high adherence of patients to the treatment and it markedly improves compliance.

Orbital reconstruction in the dog, cat, and horse.

To describe an adaptable method for reconstruction of the orbit following partial orbitectomy. One horse, one cat, and four dogs. Following partial orbitectomy for removal of bone and soft tissue affected by pathologic processes, reconstruction was achieved. Cerclage wires were used to reconstitute the orbital rim and other salient facial contours involved in excisions. These wires were then covered with a prolene mesh, first inside the orbit and then outwards over the affected extraorbital areas. Thereafter, a collagen sheet was placed over the mesh. Finally, subcutis and skin were closed over the construct. All operated eyes remained visual with normal position, direction, and mobility. Eyelid function, tear production, and nasolacrimal function were preserved. Side effects were mild and temporary, but animals requiring a lateral-posterior surgical approach experienced concavity to the side of the head posterior to the orbital ligament region. One bone tumor out of three recurred. The reconstruction method presented offers excellent results tectonically, cosmetically, and functionally, even following extensive orbitectomy. By adapted application of three reconstruction steps using readily available materials, large defects may be surgically repaired. Once orbitectomy is mastered, reconstruction requires no additional specialized techniques or equipment. © 2016 American College of Veterinary Ophthalmologists.

OBJECTIVE: To assess blockade of matrix metalloproteinase (MMP)-2 and MMP-9, as well as the variation in FEV1, in patients with lymphangioleiomyomatosis (LAM) treated with doxycycline (a known MMP inhibitor) for 12 months. METHODS: An open-label, single-arm, interventional clinical trial in which LAM patients received doxycycline (100 mg/day) for 12 months. Patients underwent full pulmonary function testing, a six-minute walk test, and quality of life assessment, as well as blood and urine sampling for quantification of MMP-2, MMP-9, and VEGF-D levels-at baseline, as well as at 6 and 12 months after the initiation of doxycycline. RESULTS: Thirty-one LAM patients received doxycycline for 12 months. Although there was effective blockade of urinary MMP-9 and serum MMP-2 after treatment, there were no significant differences between pre and post-doxycycline serum levels of MMP-9 and VEGF-D. On the basis of their response to doxycycline (as determined by the variation in FEV1), the patients were divided into two groups: the doxycycline-responder (doxy-R) group (n = 13); and the doxycycline-nonresponder (doxy-NR) group (n = 18). The patients with mild spirometric abnormalities responded better to doxycycline. The most common side effects were mild epigastric pain, nausea, and diarrhea. CONCLUSIONS: In patients with LAM, doxycycline treatment results in effective MMP blockade, as well as in improved lung function and quality of life in those with less severe disease. However, these benefits do not seem to be related to the MMP blockade, raising the hypothesis that there is a different mechanism of action. PMID:23503480

Patients with mastocytosis and wasp venom allergy (WA) may benefit from venom immunotherapy (VIT). However, fatal insect sting reactions have been described in mastocytosis patients despite previous immunotherapy. We investigated the safety and efficacy of (rush) VIT in patients with mastocytosis and WA. To investigate the safety and efficacy of (rush) VIT in patients with mastocytosis and WA. We describe nine patients with cutaneous mastocytosis and WA who received VIT. Cutaneous mastocytosis was confirmed by histopathology and systemic mastocytosis was diagnosed according to World Health Organization criteria. VIT was given according to a rush protocol. Given the difference in safety and efficacy of VIT in patients with WA and honeybee venom allergy, we reviewed the literature for VIT with the focus on WA patients with mastocytosis and addressed the difference between patients with cutaneous versus systemic mastocytosis. Nine patients had WA and mastocytosis, of whom six had cutaneous mastocytosis, two combined cutaneous and systemic mastocytosis and one systemic mastocytosis. All patients received rush IT with wasp venom. Most patients had only mild local side effects, with no systemic side effects during the course of VIT. One patient had a systemic reaction upon injection on one occasion, during the updosing phase, with dyspnoea and hypotension, but responded well to treatment. Immunotherapy was continued after temporary dose adjustment without problems. Two patients with a previous anaphylactic reaction were re-stung, without any systemic effects. VIT is safe in cutaneous mastocytosis patients with WA, while caution has to be made in case of systemic mastocytosis. VIT was effective in the patients who were re-stung.

Nonsteroidal anti-inflammatory analgesics (NSAIDs) are useful in cancer pain but the specific use of subcutaneous parecoxib has not been previously reported. This pilot study aimed to establish the efficacy and side effect profile of short-term sequential single daily dose subcutaneous parecoxib sodium in patients with severe cancer bone pain. Nineteen hospitalized patients with advanced cancer and uncontrolled malignant bone pain (9 males, 10 females) received 24 courses of one, two, or three days sequential therapy with 'off-label' daily subcutaneous parecoxib. All patients were receiving opioid therapy; the median baseline daily oral equivalent dose (OED) of morphine was 180 mg. Pain was assessed at baseline, 24 hours, 48 hours, and 72 hours. Pain scores as assessed on an 11-point numeric pain rating scale (NPRS), any side effects including subcutaneous site reactions, as well as patient satisfaction rating with analgesia were recorded. A clinically significant decrease in pain scores was defined as a reduction of two or more points on the NPRS. Median pain score of all patient treatments decreased from 7 to 4.5 at 24 hours (p<0.001) and 4.0 at 48 hours. A response was seen in 17 (71%) of the 24 treatments at 24 hours. There was no difference between median negative change in pain scores in 19 (79%) treatments where pain was either strongly movement related, or in 22 (94%) treatments where local bone tenderness was more pronounced. No major side effects were observed during treatment. One patient died from pulmonary embolism after cessation of concurrent prophylactic low molecular weight heparin prior to staging liver biopsy. Subcutaneous site reactions occurred in 2 (8%) treatments and were mild and self limiting. Short-term daily subcutaneous parecoxib injection was effective for malignant bone pain when added to existing analgesic therapy and was well tolerated. Further research is warranted into the short-term use of parecoxib in hospitalized patients with intractable malignant bone pain.

To select the misoprostol dose to be used in a large multicentre randomised trial comparing misoprostol with oxytocin in the routine management of the third stage of labour. Randomised pilot trial, double-blinded with the use of double placebos. Two of the nine hospitals that will participate in the main multicentre trial. The hospitals were located in Johannesburg, South Africa and Khon Kaen, Thailand. Women during second stage of labour about to be delivered vaginally. The trial had three arms: misoprostol 400 microg versus misoprostol 600 microg versus intramuscular oxytocin 10 IU. Each group received an injection and three tablets immediately after the birth of the baby. Shivering and pyrexia rates were the main outcome measures. Data on other side effects and characteristics of the third stage of labour were also collected. Side effects were noted as none, mild, moderate or severe. Both shivering and pyrexia (temperature > 38 degrees C) were most common in the 600 microg misoprostol group (28% and 7.5% for shivering and pyrexia, respectively) compared with 400 microg misoprostol (19% and 2%), and the oxytocin group (12.5% and 3%). The increase in shivering in the misoprostol 600 microg group was due primarily to a higher rate of moderate shivering. None of the women had a temperature > 40 degrees C. There were no increases in severe side effects and other adverse events in the misoprostol 600 microg group. When used in the management of the third stage of labour oral misoprostol is associated with an increase in the rate of moderate shivering and pyrexia which seems to be dose-related. Based on the results of this pilot trial, the Steering Committee has decided to use 600 microg misoprostol in the main trial, comparing it with oxytocin, in order to achieve higher effectiveness.

PURPOSE: To investigate the efficacy and safety of midodrine for treatment of patients with orthostatic hypotension due to autonomic failure. PATIENTS: Ninety-seven patients with orthostatic hypotension were randomized in a 4-week, double-blinded, placebo-controlled study with a 1-week placebo run-in period. Patients ranged in age from 22 to 86 years (mean: 61 years). METHODS: After a 1-week run-in phase, either placebo or midodrine at a dose of 2.5 mg, 5 mg, or 10 mg was administered three times a day for 4 weeks. Both the placebo group and the 2.5-mg midodrine group received constant doses throughout the double-blind phase. The patients receiving 5 mg or 10 mg of midodrine were given doses that were increased at weekly intervals by 2.5-mg increments until the designated dose was reached. Efficacy evaluations were based on an improvement at 1-hour postdose in standing systolic blood pressure and in symptoms of orthostatic hypotension (syncope, dizziness/lightheadedness, weakness/fatigue, and low energy level). RESULTS: Midodrine (10 mg) increased standing systolic blood pressure by 22 mm Hg (28%, p < 0.001 versus placebo). Midodrine improved (p < 0.05) the following symptoms of orthostatic hypotension compared to placebo: dizziness/lightheadedness, weakness/fatigue, syncope, low energy level, impaired ability to stand, and feelings of depression. The overall side effects were mainly mild to moderate. One or more side effects were reported by 22% of the placebo group compared with 27% of the midodrine-treated group. Scalp pruritus/tingling, which was reported by 10 of 74 (13.5%) of the midodrine-treated patients, was most frequent. Other reported side effects included supine hypertension (8%) and feelings of urinary urgency (4%). CONCLUSION: We conclude that midodrine is an effective and well-tolerated treatment for moderate-to-severe orthostatic hypotension associated with autonomic failure.

The onset of vasomotor symptoms in postmenopausal women represents the beginning of a hard period from the emotional point of view which involves some of the most important neurotransmitters. Hot flushes and insomnia associated with a state of anxiety that affect postmenopausal women are included in an index known as the Kupperman Index. The use of nutraceuticals in Italy is increasingly widespread, and only 6-8% of women currently choose to take hormone replacement therapy. The action of these natural supplements primarily depends on the selection of substances and the dose of each single ingredient. Moreover, it also depends on the range of vasomotor symptoms (from mild to moderate/severe). The aim of this study was to test the action of a new product without phytoestrogens containing Cimicifuga racemosa, chasteberry (Vitex agnus-castus), hyaluronic acid, zinc and ginger (ElleN®) in two different groups of women: one with mild and the other with moderate/severe menopausal symptoms. All women received a dose of one tablet per day of ElleN® for three months. Results showed a significant reduction in the Kupperman Index in both groups. The treatment was particularly effective against hot flushes associated with night insomnia and anxiety. The product was well tolerated, did not cause any side effects, and none of the subjects dropped out of the study. In conclusion, it can be stated that the supplement evaluated in the present study is able to reduce moderate/severe menopause symptoms.

Epilepsy is one of the most common neurologic disorders. Vagus nerve stimulation (VNS), first investigated in 1938 and subsequently studied as a potential therapy for epilepsy. The FDA approved the use of VNS in 1997 as an adjunctive non-pharmacologic symptomatic treatment option for refractory epilepsy for adults and adolescents over 12years. VNS can cause laryngeal and voice side effects that can be managed by otolaryngologists safely and effectively. This study is to review the outcomes of vagal nerve stimulator (VNS) implantation in terms of the surgical procedures, complications, seizure frequency, and the clinical effect on larynx and vocal folds motion. Series of thirty consecutive patients who had VNS implantation between 2007 and 2014 were recruited. Seizure-frequency outcome, surgical complications and device adverse effects of VNS were retrospectively reviewed. Additional evaluation included use of the Voice Handicap Index and Maximum Phonation Time (MPT) were conducted before and after the implantation. Videolaryngoscopy was used to evaluate the vocal fold mobility before and after the VNS implantation. Seizure frequency reduction over a minimum of 2years of follow up demonstrated: 100% in seizure frequency reduction in 1 patient, drastic reduction in seizure frequency (70-90%) in 9 patients, a good reduction in terms of seizure frequency (50%) in 8 patients, a 30% reduction in 5 patients, no response in 6 patients, and 1 patient had increased frequency. The most commonly reported adverse effects after VNS activation were coughing and voice changes with pitch breaks, as well as mild intermittent shortness of breath in 33% of patients. For those patients secondary supraglottic muscle tension and hyper function with reduced left vocal fold mobility were noticed on videolaryngoscopy, though none had aspiration problems. Surgical complications included a wound dehiscence in one patient (3%) which was surgically managed, minor intra-operative bleeding 3%; a superficial wound infection in one patient (3%) which was treated conservatively, none of the complications necessitated VNS removal. VNS appears to be an effective non-pharmacologic adjuvant therapy in patients with medically refractory seizures. With the favorable adverse-effect profile previously described, VNS is generally well tolerated and of a great benefit to such patients. Laryngeal side effects, of which hoarseness being of the greatest repetition, are the most common after the VNS implantation. VNS can affect the voice and reduced vocal cord motion on the implantation side with secondary supraglottic muscle tension. Otolaryngologists are not only capable of performing VNS implantation, but can also manage surgical complications, assess laryngeal side effects and treat them as needed.

We found previously in a lesion study that the right-sided sector of the ventromedial prefrontal cortices (VMPCs) was critical for social/emotional functioning and decision-making, whereas the left side appeared to be less important. It so happened that all but one of the subjects in that study were men, and the one woman did not fit the pattern very well. This prompted a follow-up investigation, in which we explored the following question: Does gender play a role in the development of defects in social conduct, emotional functioning and decision-making, following unilateral VMPC damage? We culled from our Patient Registry same-sex pairs of men or women patients who had comparable unilateral VMPC damage in either the left or right hemisphere. Two male pairs and one female pair were formed, and we included two additional women with unilateral right VMPC damage (8 patients in all). The domains of measurement covered social conduct, emotional processing and personality, and decision-making. We found a systematic effect of gender on the pattern of left-right asymmetry in VMPC. In men, there were severe defects following unilateral right VMPC damage, but not following left-sided damage. In women, there were defects following unilateral left VMPC damage; following right-sided damage, however, defects were mild or absent. The findings suggest that men and women may use different strategies to solve similar problems--e.g. men may use a more holistic, gestalt-type strategy, and women may use a more analytic, verbally-mediated strategy. Such differences could reflect asymmetric, gender-related differences in the neurobiology of left and right VMPC sectors.

Platelet-rich plasma (PRP) which contains large amounts of growth factors has been tried to enhance therapeutic efficacy of laser treatment for acne scar with unknown underlying mechanism. The present study was conducted to investigate the molecular mechanism of increased clinical efficacy of PRP when combined with fractional laser treatment for treating acne scars. Subjects with mild to moderate acne scars were treated with two sessions of fractional CO 2 laser therapy given with and without co-administration of PRP. Skin biopsy specimens were obtained at baseline, 1, 3, 7, and 28 days for investigation of molecular profiles associated with skin changes produced by laser plus PRP treatment. The PRP treatment increased clinical efficacy with decreased severity of adverse effects such as erythema, swelling and oozing. Productions of TGFβ1 and TGFβ3 proteins were more highly elevated on the PRP-treated side of the face compared to the control side at day 28. Furthermore, PRP-treated side showed significant increase of c-myc, TIMP, and HGF expression. Experimental fibroblast culture model was also used. PRP administration after laser irradiation increased expressions of p-Akt, TGFβ1, TGFβ3, β-catenin, collagen 1, and collagen 3 in both dose-dependent and time dependent manners in fibroblast. Moreover, we acquired clinical and histological data through randomized control clinical trial. Taken together with human study results combined with the data from cell experiments we suggest that PRP treatment increased fibrogenetic molecules induced by fractional CO 2 laser, which have association with clinical effect.

PurposeTo evaluate the chronological effects of irreversible electroporation (IRE) on large hilar bile ducts in an in vivo porcine model correlated with computed tomography (CT) cholangiography and histopathology.Materials and MethodsTwelve IRE zones were made along hilar bile ducts intraoperatively under ultrasound (US)-guidance in 11 pigs. Paired electrodes were placed either on opposing sides of the bile duct (straddle [STR]) or both on one side of the bile duct (one-sided [OSD]). The shortest electrode-to-duct distance was classified as periductal (≤2 mm) or nonperiductal (>2 mm). CT cholangiography and laboratory tests were performed before IRE and again at 2 days, 4 weeks, and 8 weeks after IRE.more » Degree of bile duct injury were graded as follows: grade 0 = no narrowing; grade 1 = ≤50 % duct narrowing; grade 2 = >50 % narrowing without proximal duct dilatation; grade 3 = grade 2 with proximal duct dilatation; and grade 4 = grade 3 with enzyme elevation. Pigs were selected for killing and histopathology at 2 days, 4, and 8 weeks.ResultsNonperiductal electrode placement produced no long-term strictures in 5 of 5 ducts. Periductal electrode placement produced mild narrowing in 6 of 7 ducts: 5 grade 1 and 1 grade 2. None showed increased enzymes. There was no significant difference between STR versus OSD electrode placement. Histopathology showed minor but relatively greater ductal mural changes in narrowed ducts.ConclusionIn the larger hilar ducts, long-term patency and mural integrity appear resistant to IRE damage with the energy deposition used, especially if the electrode is not immediately periductal in position.« less

[Efficiency of fenticonazole for the treatment of vaginal candidiasis].

2012-01-01

Uncomplicated vulvovaginal candidiasis appears in 75% women of reproductive age. The most frequent causes are Candida albicans (85-95%) or C. glabrata, and infrequently C. krusei, C. tropicalis, C. parapsilosis, C. pseudotropicalis, etc. The aim of the study was to investigate efficiency and safety of fenticonazole for vaginal candidiasis treatment. Therapeutic effect of a single 600 mg fenticonasole vaginal capsule was observed in 417 women, aged 16-67, in five centers in Serbia. In all women, before the treatment, vaginal candidiasis was confirmed by testing of vaginal smear. Based on smear findings and associated symptoms observed on the 7th and 28th day after therapy administration, treatment results were evaluated. On the next day after drug application the patients recorded by using a questionnaire their own feelings on withdrawal symptoms and possible side effects in the period prior to the first control. Control after seven days showed a statistically significant decrease of symptoms. In 385 women, vaginal smear was found negative to yeast and yeast blastospores. Within the first seven days after treatment 84 women had to repeat therapy due to the persistence of symptoms or positive vaginal smear. After 28 days we recorded full recovery in 392 patients, clinical improvement in eight, no change in 16, and deterioration in one patient only. Side effects were very seldom, mostly in the form of a slight redness of the vulva and vagina, and mild itching during several days. Our observations confirmed good efficacy and safety of fenticonazole in the treatment of vaginal candidiasis.

Magnetic resonance imaging (MRI) is a useful diagnostic tool for the evaluation of congenital or acquired brain lesions. But, in all of less than 8-year-old children, pharmacological agents and procedural sedation should be used to induce motionless conditions for imaging studies. The purpose of this study was to compare the efficacy and safety of combination of chloral hydrate-hydroxyzine (CH+H) and chloral hydrate-midazolam (CH+M) in pediatric MRI sedation. In a parallel single-blinded randomized clinical trial, sixty 1-7-year-old children who underwent brain MRI, were randomly assigned to receive chloral hydrate in a minimum dosage of 40 mg/kg in combination with either 2 mg/kg of hydroxyzine or 0.5 mg/kg of midazolam. The primary outcomes were efficacy of adequate sedation (Ramsay sedation score of five) and completion of MRI examination. The secondary outcome was clinical side-effects. Twenty-eight girls (46.7%) and 32 boys (53.3%) with the mean age of 2.72±1.58 years were studied. Adequate sedation and completion of MRI were achieved in 76.7% of CH+H group. Mild and transient clinical side-effects, such as vomiting of one child in each group and agitation in 2 (6.6 %) children of CH+M group, were also seen. The adverse events were more frequent in CH+M group. Combinations of chloral hydrate-hydroxyzine and chloral hydrate-midazolam were effective in pediatric MRI sedation; however, chloral hydrate-hydroxyzine was safer.

Carbon dioxide (CO2 ) and erbium-yttrium aluminum garnet (Er-YAG) lasers are the gold standards in ablative skin resurfacing. Neodymium-doped yttrium aluminum garnet (Nd-YAG) laser is considered a nonablative skin resurfacing laser whose usage is limited due to its high cost. To assess the efficacy and safety of Nd-YAG as an ablative resurfacing laser and to compare the results with those previously published for CO2 and Erbium-YAG lasers. A total of 296 patients (251 female and 45 male) with Fitzpatrick skin types III-IV and dermatological conditions amenable to ablative skin resurfacing participated in this study. Nd-YAG laser parameters assessed were wavelength (1064 nm), pulse duration (5 ms), fluence (10 J/cm(2) ), and spot size (8-10 mm). Efficacy of Nd-YAG laser was assessed by comparing pre- and posttreatment photographs. An improvement of 30-80% was observed in treated patients. The degree of improvement correlated positively with the number of laser sessions. The most common side effect was hyperpigmentation. Other side effects were less common and mild in intensity compared with published results for gold standard ablative lasers. Not only was the Nd-YAG laser found to be as effective as Er-YAG and CO2 lasers, but treated patients also had shorter recovery and treatment times, and at lower cost. © 2013 Wiley Periodicals, Inc.

Abstract Background: Skin laxity and cellulite on the buttocks and thighs are two common cosmetic concerns. Skin tightening with radiofrequency (RF) devices has become increasingly popular. The purpose of this study is to evaluate the efficacy and safety of a topical skin laxity tightening agent when used in combination with an RF device. A double-blinded, randomized clinical trial enrolled twenty females with mild-to-moderate skin laxity on the posterior thighs/buttocks. Each subject underwent two monthly treatments with an RF source (Alma Accent) to both legs. Subjects were then randomized to apply a topical agent (Skinceuticals Body Tightening Concentrate) twice daily to only one designated thigh/buttock throughout the eight-week duration of the study. All subjects were evaluated for improvement in lifting, skin tone, radiance, firmness/tightness, skin texture, and overall appearance based on photographic evaluation by blinded investigators at 12 weeks following the final RF treatment. A statistically significant improvement was found in the overall appearance on both sides treated with the RF device when compared to baseline. However, the area treated with the topical agent showed a statistically significantly greater degree of improvement than the side where no topical agent was applied. No adverse effects were reported. The use of a novel skin tightening agent used after RF procedures is both safe and effective for treatment of skin laxity on the buttocks and thighs. Combined therapy leads to a better result.

A combination capsule of bismuth, metronidazole, and tetracycline plus omeprazole given as 10-day therapy has an overall effectiveness of 92-93% in per-protocol analysis (Grade B) with eradication of 86-91% of metronidazole-resistant Helicobacter pylori. This study aimed to explore whether extending the duration to 14 days would improve overall effectiveness per protocol to ≥95% (Grade A) in a population in which metronidazole resistance was anticipated to exist. A one-arm, open-label pilot study of H. pylori-infected, asymptomatic/mildly dyspeptic adults, Hispanic residents of El Paso, Texas, received a 14-day course of omeprazole, plus the combination capsule. We cultured and Gram-stained specimens obtained using a minimally invasive orogastric brush. Helicobacter pylori status was determined by (13)C-urea breath test at 4 or more weeks post-therapy. Forty-seven subjects (7 men and 40 women, average age 42 years) were entered. The per-protocol effectiveness was 97.1% (33/34) (95% mid-P CI: 86.3, 99.9); 100% of metronidazole-resistant strains were eradicated. Side effects were mild and self-limited but contributed to nonadherence. Therapy taken for <10 days was more likely to result in eradication failure (p < .001). Office-based orogastric brushing was well tolerated; positive cultures were obtained in 95%. Gram staining showed H. pylori-like forms in all specimens. This pilot study supports the concept that 14-day OBMT therapy is likely to be more efficacious for H. pylori eradication (Grade A, PP basis) than a 10-day course where metronidazole resistance is suspected. If confirmed, 14 days should be recommended in populations where metronidazole resistance is common. © 2012 Blackwell Publishing Ltd.

Laryngeal microsurgery is performed to assess disorders of the larynx. Parecoxib is the only parenterally administered selective cyclooxygenase (COX)-2 inhibitor widely used in acute pain control. The purpose of this study is to assess the analgesic effects of parecoxib compared with morphine for postoperative sore throat in patients undergoing laryngeal microsurgery. Fifty patients were randomly allocated to receive either parecoxib 0.5 mg/kg or morphine 50 μg/kg prior to anesthesia induction. General anesthesia was maintained with sevoflurane 2-4%. Postoperative sore throat and other outcomes were measured at a postanesthesia care unit (PACU) 4 hours and 24 hours postoperatively. The severity of postoperative sore throat was assessed by sore throat score as follows: none (0) = no pharyngeal or laryngeal discomfort; mild (1) = no pain at rest, but swallowing induced mild pain or discomfort; moderate (2) = constant pain without swallowing exacerbation; and severe (3) = constant pain with swallowing or respiratory exacerbation. The incidences of postoperative side effects (nausea, vomiting, itching, dizziness, and somnolence) were also recorded. Demographic data from the parecoxib (n = 25) and morphine (n = 25) groups did not differ significantly. The parecoxib group depicted similar sore throat scores as the morphine group at three measured postoperative time points. Patients requiring postoperative analgesics were comparable between the parecoxib group and morphine group (2/25, 8% vs. 3/25, 12%, p = 0.64). Overall postoperative adverse events were fewer in the parecoxib group than the morphine group (3/25, 12% vs. 9/25, 36%, p = 0.047). Both parecoxib and morphine are effective to attenuate postoperative sore throat after laryngeal microsurgery. Parecoxib may be an effective and well-tolerated injectable analgesic to manage postoperative sore throat after laryngeal microsurgery. Copyright © 2014. Published by Elsevier Taiwan.

Acne treatment by a mid-infrared laser may be unsatisfactory due to deeply situated acne-affected sebaceous glands which serve as its target. Skin manipulation by vacuum and contact cooling may improve laser-skin interaction, reduce pain sensation, and increase overall safety and efficacy. To evaluate the safety and efficacy of acne treatment using an integrated cooling-vacuum-assisted 1540-nm erbium:glass laser, a prospective interventional study was conducted. It included 12 patients (seven men and five women) suffering from mild-to-moderate acne vulgaris. The device utilizes a mid-infrared 1540-nm laser (Alma Lasers Ltd. Caesarea, Israel), which is integrated with combined cooling-vacuum-assisted technology. An acne lesion is initially manipulated upon contact by a vacuum-cooling-assisted tip, followed by three to four stacked laser pulses (500-600 mJ, 4 mm spot size, and frequency of 2 Hz). Patients underwent four to six treatment sessions with a 2-week interval and were followed-up 1 and 3 months after the last treatment. Clinical photographs were taken by high-resolution digital camera before and after treatment. Clinical evaluation was performed by two independent dermatologists, and results were graded on a scale of 0 (exacerbation) to 4 (76-100 % improvement). Patients' and physicians' satisfaction was also recorded. Pain perception and adverse effects were evaluated as well. All patients demonstrated a moderate to significant improvement (average score of 3.6 and 2.0 within 1 and 3 months, respectively, following last treatment session). No side effects, besides a transient erythema, were observed. Cooling-vacuum-assisted 1540-nm laser is safe and effective for the treatment of acne vulgaris.

Controversies in neurology: why monoamine oxidase B inhibitors could be a good choice for the initial treatment of Parkinson's disease.

Early initiation of pharmacotherapy in Parkinson's disease (PD) is nowadays widely advocated by experts since the delay of treatment has shown to be associated with a significant deterioration of health related quality of life in affected patients. Due to marked advances in PD treatment during the last decades, physicians are nowadays fortunately equipped with a variety of substances that can effectively ameliorate emerging motor symptoms of the disease, among them levodopa, dopamine agonists and monoamine oxidase type B (MAO-B) inhibitors. Despite numerous drug intervention trials in early PD, there is however still ongoing controversy among neurologists which substance to use for the initial treatment of the disease. In multiple studies, MAO-B inhibitors, such as selegiline and rasagiline, have shown to provide mild symptomatic effects, delay the need for levodopa, and to reduce the incidence of motor fluctuations. Although their symptomatic efficacy is inferior compared to dopamine agonists and levodopa, MAO-B inhibitors undoubtedly have fewer side effects and are easy to administer. In contrary to their competitors, MAO-B inhibitors may furthermore offer a chance for disease modification, which so far remains a major unmet need in the management of PD and eventually makes them ideal candidates for the early treatment of the disease. MAO-B inhibitors may constitute a preferable therapeutic option for early PD, mainly due to their favourable safety profile and their putative neuroprotective capabilities. Since the symptomatic effects of MAO-B inhibitors are comparatively mild, dopamine agonists and levodopa should however be considered for initial treatment in those PD patients, in whom robust and immediate symptomatic relief needs to be prioritized.

To evaluate the efficacy and tolerability of levetiracetam monotherapy in dogs with structural epilepsy. Retrospective case series. Nineteen client-owned dogs with structural epilepsy. Seizure frequencies after initiation of treatment were used to evaluate the efficacy of levetiracetam monotherapy. Seizure control was considered good if no seizures occurred within three months of starting treatment or poor if seizures returned within one month of starting treatment. Tolerability was evaluated by considering the occurrence and severity of any reported side effects. Ten of the 19 dogs were considered to have a good response to treatment with 7 achieving complete seizure freedom. Nine dogs were considered to have poor response to treatment. There was a statistically significant reduction in the percentage of patients experiencing cluster seizures from 68.4% to 15.8% (p=0.002). Side effects were noted in 8 of the 19 dogs but were considered mild in all cases. Follow-up times ranged from 12 days to 426 days. When used in conjunction with other appropriate therapies, levetiracetam may be an efficacious option for monotherapy in dogs with structural epilepsy. Its tolerability makes it a suitable option for use in a wide variety of patients. © British Veterinary Association (unless otherwise stated in the text of the article) 2017. All rights reserved.

To assess the feasibility and tolerability of intermittent androgen suppression therapy (IAS) in prostate cancer. Patients with recurrent or metastic prostate cancer received cyclical periods of treatment with leuprolide acetate and nilutamide for 8 months, and rest periods. Cycles were repeated at progression until the treatment failed to achieve normal prostate-specific antigen (PSA) levels. Patients were followed with PSA level, testosterone level, haemoglobin level, weight and bone mineral density evaluations. The median time to treatment failure, recovery from anaemia, or normalization of testosterone level was estimated by the Kaplan-Meier method. In all, 95 patients received 245 cycles; the median duration of rest periods was 8 months and median time to treatment failure 47 months. Testosterone recovery during rest periods was documented in 117 (61%) of cycles. Anaemia was mild and reported in 33%, 44% and 67% of cycles 1, 2 and 3, respectively. Sexual function recovered during the rest periods in 47% of cycles. There was no significant overall change in body mass index at the end of the treatment period. Osteoporosis was documented in at least one site evaluated in 41 patients (37%). IAS has the potential to reduce side-effects, including recovery of haemoglobin level, return of sexual function and absence of weight gain at the end of the study period.

The efficacy and safety of three different doses of granisetron (2 micrograms kg-1, group A; 10 micrograms kg-1, group B; 40 micrograms kg-1, group C) were compared in a randomised, double-blind study of 157 patients due to receive high-dose cisplatin therapy (mean dose > 97 mg m-2). In each group, up to two 3 mg rescue doses of granisetron were allowed if more than mild nausea or vomiting occurred. In group A 30.8%, in group B 61.5% and in group C 67.9% of patients were complete responders (i.e. no vomiting or nothing worse than mild nausea) during the first 24 h. These differences are significant between groups A and B, and A and C. There were no statistically significant differences in any efficacy variable between the 10 micrograms kg-1 and 40 micrograms kg-1 groups, although in each case the trend favoured the higher dose. Additional rescue doses resulted in resolved or improved symptoms in 95.3% for the first rescue dose and 93.3% for the second. Over the 7 days of the study, 82.7%, 82.7% and 86.8% of patients in groups A, B and C respectively were treated with granisetron alone. Headache was the most common side-effect, reported by 9.6% of patients; the majority of headaches were mild. There was no difference between the treatment groups regarding the adverse event rate. We concluded that prophylactic doses of 10 or 40 micrograms kg-1 lead to a safe and satisfactory degree of control of nausea and vomiting induced by high-dose cisplatin. PMID:8180032

Examination of 2 life masks of Abraham Lincoln's face was performed by means of 3-dimensional laser surface scanning. This technique enabled documentation and analysis of Lincoln's facial contours and demonstrated his marked facial asymmetry, particularly evident in the smaller left superior orbital rim. This may have led to retroplacement of the trochlea on the left side, leading, in turn, to the mild superior oblique paresis that was manifested intermittently during adulthood.

A 14-month-old Japanese Black heifer presented with unilateral epistaxis and mild swelling of the right face. Radiography revealed a mass with increased radiopacity on the right side of the nasal bridge, extending to the left side. Intranasal endoscopy confirmed a large tumor-like structure protruding into the nasal cavity. Following euthanasia, cranial computed tomography (CT) was performed, revealing a tumor 24.3 × 17.5 × 14.8 cm in size. The tumor occupied the entire right nasal cavity and the frontal and sphenoid sinuses. Histopathological examination revealed that the tumor consisted of well-differentiated trabecular bones and loose connective tissue. Based on these findings, a diagnosis of osteoma was established. This report describes a case of osteoma with an acute course in a Japanese Black heifer. PMID:28579581

We aimed to clarify postural control deficits in older adults with mild cognitive impairment (MCI) at high risk of falling by addressing the inhibitory process. This study involved 376 community-dwelling older adults with MCI. Participants were instructed to execute forward stepping on the side indicated by the central arrow while ignoring the 2 flanking arrows on each side (→→→→→, congruent, or →→←→→, incongruent). Initial weight transfer direction errors [anticipatory postural adjustment (APA) errors], step execution times, and divided phases (reaction, APA, and swing phases) were measured from vertical force data. Participants were categorized as fallers (n = 37) and non-fallers (n = 339) based on fall experiences in the last 12 months. There were no differences in the step execution times, swing phases, step error rates, and APA error rates between groups, but fallers had a significantly longer APA phase relative to non-fallers in trials of the incongruent condition with APA errors (p = 0.005). Fallers also had a longer reaction phase in trials with the correct APA, regardless of the condition (p = 0.01). Analyses of choice stepping with visual interference can detect prolonged postural preparation as a specific falling-associated deficit in older adults with MCI. © 2015 S. Karger AG, Basel.

The present study was designed to investigate the risk factors affecting the conversion to open surgery in retroperitoneal laparoscopic nephrectomy of nonfunctioning renal tuberculosis (TB). The records of 144 patients who underwent a retroperitoneal laparoscopic nephrectomy procedure by a single surgeon were retrospectively reviewed. The following factors, including age, sex, body mass index (BMI), diabetes status, hypertension status, side of kidney, size of kidney, degree of calcification, mild perirenal extravasation, contralateral hydronephrosis, the time of anti-TB, and surgeon experience were analyzed. Univariate and multivariate logistic regression analyses were used for statistical assessment. Twenty-three patients were converted to open surgery and the conversion rate was 15.97%. In univariate analysis, BMI ≥35 kg/m 2 (p = 0.023), hypertension (p = 0.011), diabetes (p = 0.003), and kidney size (p = 0.032) were the main factors of conversion to open surgery. Sex, age, side, anti-TB time, calcification, mild extravasation, and surgeon experience were not significantly related. In multivariate regression analysis, BMI ≥35 kg/m 2 , hypertension, diabetes, and enlargement of kidney were the most important factors for conversion to open surgery. Depending on the results achieved by a single surgeon, BMI ≥30 kg/m 2 , diabetes, hypertension, and enlargement of kidney significantly increased the conversion risk in retroperitoneal laparoscopic nephrectomy for nonfunctioning renal TB.

An 8 years old male Burmese Red Serow ( Capricornis sumatraensis sub species rubidus ) from Aizawl Zoological Park was presented to the Teaching Veterinary Clinical Complex. An exploratory skin scraping revealed existence of nymphal as well as adult stages of mites of the Psoroptes spp. which were not associated with any overt lesions typical to mite infestation such as pruritus, erythema or scaling of the epidermis. The mites were identified as per their morphology, size and shape. Haemato-biochemical analysis revealed alteration of certain haematological and biochemical parameters. The red blood corpuscles were found to have anucleate cells with mild to absent central pallor. The absolute counts showed neutrophilic leucocytosis with mild monocytosis and lymphocytosis. Eosinophilic count was towards the higher side, indicating that the infestation was mild. The serum calcium, albumin, triglyceride, urea nitrogen (BUN) were found to be lower than normal, whereas serum ALT, AST, LDH, ALP and serum amylase were higher than the established reference indices. Due to lack of haemato-biochemical reference values specific to captive Serow, emphasis was given in this report to establish baseline data for this species.

Background The studio di intervento nel decadimento vascolare lieve (IDEALE study) was an open multicenter Italian study, the aim of which was to assess the effectiveness and safety of oral citicoline in elderly people with mild vascular cognitive impairment. Methods The study was performed in 349 patients. The active or citicoline group was composed of 265 patients and included 122 men and 143 women of mean age 79.9 ± 7.8 years selected from six Italian regions. Inclusion criteria were age ≥ 65 years, Mini-Mental State Examination (MMSE) score ≥ 21, subjective memory complaints but no evidence of deficits on MMSE, and evidence of vascular lesions on neuroradiology. Those with probable Alzheimer’s disease were excluded. The control group consisted of 84 patients, including 36 men and 48 women of mean age 78.9 ± 7.01 (range 67–90) years. Patients included in the study underwent brain computed tomography or magnetic resonance imaging, and plasma dosage of vitamin B12, folate, and thyroid hormones. Functional dependence was investigated by scores on the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales, mood was assessed by the Geriatric Depression Scale (GDS), and behavioral disorders using the Neuropsychiatric Inventory scale. Comorbidity was assessed using the Cumulative Illness Rating Scale. An assessment was made at baseline (T0), after 3 months (T1), and after 9 months (T2, ie, 6 months after T1). The main outcomes were an improvement in MMSE, ADL, and IADL scores in the study group compared with the control group. Side effects were also investigated. The study group was administered oral citicoline 500 mg twice a day throughout the study. Results MMSE scores remained unchanged over time (22.4 ± 4 at T0; 22.7 ± 4 at T1; 22.9 ± 4 at T2), whereas a significant difference was found between the study and control groups, both in T1 and in T2. No differences were found in ADL and IADL scores between the two groups. A slight but not statistically significant difference was found in GDS score between the study and control groups (P = 0.06). No adverse events were recorded. Conclusion: In this study, citicoline was effective and well tolerated in patients with mild vascular cognitive impairment. Citicoline activates biosynthesis of phospholipids in neuronal membranes, increases brain metabolism as well as norepinephrine and dopamine levels in the central nervous system, and has neuroprotective effects during hypoxia and ischemia. Therefore, citicoline may be recommended for patients with mild vascular cognitive impairment. PMID:23403474

Collagenase Clostridium histolyticum (CCH) injection and manipulation is a relatively new method for treating Dupuytren contracture that is growing in popularity. Although side effects such as swelling and ecchymosis are common, they are typically mild and self-limited. Major complications are rare but have included flexor tendon rupture and complex regional pain syndrome. This study describes a case report of 2 patients seen at our institution. Here, we report 2 patients seen at our institution each with different, yet serious complications after CCH injection and manipulation. One patient had extensive skin loss and chose amputation over reconstruction. The other patient had loss of perfusion and required finger amputation. Although it is unclear how directly the administration of CCH is connected to the observed complications, physicians should recognize the potential for serious rare complications in any treatment of Dupuytren contracture.

One-pot Suzuki-Miyaura-type and Kumada-type cross-coupling reactions of 2,4-diiodo-buta-1-enes with arylboronic acids and alkyl/aryl magnesium bromides were carried out in the presence of accessibly simple catalysts under mild conditions. As a result, some 1,1,2-trisubstituted buta-1,3-dienes were obtained including the Tamoxifen-type, which have potential adjuvant therapy in women who have suffered from breast cancer and cyclooxygenase-2-type (COX-2-type) inhibitors, some of which have been proved to elicit efficient anti-inflammatory analgesic activities and less adverse gastrointestinal side effects and to be very useful in the prophylactic treatment of a wide variety of cancers and neurodegenerative disorders.

The debate on treating subclinical hypothyroidism.

PubMed

Tng, Eng Loon

2016-10-01

Subclinical hypothyroidism (SCH) represents a mild or compensated form of primary hypothyroidism. The diagnosis of SCH is controversial, as its symptoms are non-specific and its biochemical diagnosis is arbitrary. The treatment of SCH was examined among non-pregnant adults, pregnant adults and children. In non-pregnant adults, treatment of SCH may prevent its progression to overt hypothyroidism, reduce the occurrence of coronary heart disease, and improve neuropsychiatric and musculoskeletal symptoms associated with hypothyroidism. These benefits are counteracted by cardiovascular, neuropsychiatric and musculoskeletal side effects. SCH is associated with adverse maternal and fetal outcomes that may improve with treatment. Treating SCH in children is safe and may improve growth. Importantly, the evidence in this field is largely from retrospective and prospective studies with design limitations, which precludes a conclusive recommendation for the treatment of SCH.

Involuntary movements in the elderly. Parkinson's disease and other causes.

Dyskinesia is usually lifelong and progressive; therefore, physicians generally see the disorder in elderly patients. Medical treatment must be carefully selected on the basis of the cause of the dyskinesia. Parkinsonian dyskinesia is well controlled by drug therapy. However, patients can become less responsive to a drug after years of use and may experience unwelcome side effects. Cerebellar tremor is extremely disabling because it worsens with activity, but no satisfactory therapy is available. Senile, essential, and familial tremors are also intensified by action, but they can often be suppressed with a mild tranquilizer or a beta blocker. Drug treatment of blepharospasm and spastic dysphonia has been disappointing: Facial or laryngeal surgery is sometimes required. Tardive dyskinesia is caused by neuroleptic drugs, so the only therapy for the disorder is withdrawal of the offending drug.

Acute-on-chronic liver failure due to thiamazole in a patient with hyperthyroidism and trilogy of Fallot: case report

PubMed Central

2010-01-01

Background Thiamazole is a widely used antithyroid agent that has been approved for the treatment of hyperthyroidism. Although thiamazole-induced hepatotoxicity is a main side effect, it may progress to liver failure in a very few cases. Case Presentation We described a 24-year-old patient with hyperthyroidism and trilogy of Fallot, who developed liver failure due to thiamazole. Liver biopsy showed intrahepatic cholestasis, mild inflammatory infiltrates, as well as significant fibrosis, indicating both acute and chronic liver injuries. Although a series of potent therapies were given, the patient deceased due to severe liver decompensation. Conclusions This case suggests that thiamazole-induced hepatotoxicity in the setting of advanced fibrosis increases the risk of poor outcome. Regular liver function monitoring during thiamazole therapy is therefore important. PMID:20707932

Labor pain management other than neuraxial: what do we know and where do we go next?

Rooks, Judith P

Analgesia and coping with labor pain can prevent suffering during childbirth. Nonpharmacologic methods help women manage labor pain. Strong evidence is available for the efficacy of continuous one-to-one support from a woman trained to provide nonmedical care during labor, immersion in warm water during first-stage labor, and sterile water injected intracutaneously or subcutaneously at locations near a woman's lumbosacral spine to reduce back-labor pain. Sterile water injections also reduce the incidence of cesarean deliveries. Nitrous oxide labor analgesia is not potent, but helps women relax, gives them a sense of control, and reduces and distracts their perception of pain. It is inexpensive; can be administered and discontinued safely, simply, and quickly; has no adverse effects on the normal physiology and progress of labor; and does not require intensive monitoring or co-interventions. Parenteral opioids provide mild-to-moderate labor pain relief, but cause side effects. Although observational studies have found associations between maternal use of opioids and neonatal complications, little higher level evidence is available except that meperidine is associated with low Apgar scores. Patient-controlled intravenous administration of remifentanil provides better analgesia and satisfaction than other opioids, but can cause severe side effects; continuous monitoring of arterial oxygen saturation, anesthesia supervision, one-to-one nursing, and availability of oxygen are recommended. The demand for inexpensive, simple, safe but effective labor pain management for women will undoubtedly increase in places that lack wide access to it now. © 2012, Copyright the Author Journal compilation © 2012, Wiley Periodicals, Inc.

Granisetron transdermal system improves refractory nausea and vomiting in gastroparesis.

Symptoms of gastroparesis include nausea and vomiting, which can markedly diminish quality of life. Nausea and vomiting can also make treatment with oral antiemetics problematic. Our aim was to determine whether treatment-resistant nausea and vomiting in patients with gastroparesis improve after granisetron transdermal patch (GTP) therapy. In an open-label pilot study, patients with gastroparesis and symptoms of nausea and vomiting refractory to conventional treatment were treated with GTP. After 2 weeks, patients were asked to assess their therapeutic response using the Clinical Patient Grading Assessment Scale (CPGAS; +7 = completely better; 0 = no change; -7 = very considerably worse). Responders were defined as CPGAS score >0, non-responders as ≤0. Patients (n = 36) were treated with GTP. Of these 36 patients, one patient discontinued treatment due to the GTP not adhering to the skin. Of the remaining 35 patients, 18 improved, 15 remained the same, and two worsened. The average CPGAS score was +1.8 ± 0.4 (SEM) (P < 0.05 vs 0). Of the 18 patients with improvement, the average CPGAS score was +3.7 ± 0.3 (SEM), corresponding to "somewhat" to "moderately better" improvement in nausea/vomiting. Side effects occurred in nine patients: four developed constipation, three patients had skin rash, and two reported headaches. GTP was moderately effective in reducing refractory symptoms of nausea and/or vomiting from gastroparesis in 50% of patients. Mild side effects were reported by 25% of patients. GTP may be an effective treatment for nausea and vomiting in gastroparesis, and further study is warranted.

For many years, ambulance services throughout Australia have been administering methoxyflurane as a first-line analgesic agent. However, there is a paucity of literature regarding its efficacy, safety and usage profile. The present study was designed to examine the efficacy of methoxyflurane in adults. An observational case series was conducted over a 10 month period. Adults to whom methoxyflurane was administered while traveling by ambulance to an urban teaching hospital were enrolled. Data analysed included indications for use, verbal numerical pain scores, depth of sedation and adverse effects. Data were collected via paramedic, patient and ED staff surveys. Eighty-three adult patients were enrolled over a 10 month period. A mean reduction in verbal numerical rating scale (VNRS) scores of 2.47 +/- 0.24 (on a 10-point scale) was recorded 5 min post methoxyflurane, with a total reduction of 3.21 +/- 0.24 at time of arrival at the ED. Both VNRS scores were significantly different from baseline (P < 0.0001). Fifteen patients (18.1%, 95% CI 9.8-26.4%) reported mild side-effects either during or shortly after administration. A total of 68 (81.9%, 95% CI 72.0-89.5%) of the paramedics and 60 (72.3%, 95% CI 61.4-81.6%) of the patients interviewed said that they felt satisfied with the level of analgesia provided by methoxyflurane. The use of methoxyflurane as a prehospital analgesic significantly reduced pain in patients, with no significant side-effects attributed to its use. The majority of patients and paramedics interviewed were satisfied with its effects and indicated a willingness to use it again.

2010-12-01

The purpose of this evidence-based clinical update is to identify the best evidence when selecting a long-acting local anesthetic agent for single-shot pediatric caudal anesthesia in children. A structured literature search was conducted using PubMed and Medline (OVID) using the terms "caudal" and combinations of at least two of "bupivacaine", "ropivacaine", and "levobupivacaine". The search limits included "randomized controlled trials" (RCTs), "meta-analysis", "evidence-based reviews" or "reviews", "human", and "all child: 0-18 yr". Seventeen RCTs were identified that concerned single-shot pediatric caudal anesthesia with at least two of the three drugs in question. Data were extracted for the areas of clinical efficacy and side effects. Study findings were assigned levels of evidence, and grades of recommendation were made according to Centre for Evidence-Based Medicine criteria. The three drugs investigated were found to be equivalent in terms of efficacy. Evidence showed bupivacaine with the highest incidence of motor block and ropivacaine with the lowest. Adverse effects were rare and unrelated to the choice of drug. There were no serious adverse events. None of the three agents was shown to be superior in terms of efficacy. Bupivacaine is preferred if motor block is desired, ropivacaine is preferred if motor block is to be minimized. Adverse effects in human studies are rare, mild, and unrelated to the choice of drug. Despite encountering the absence of serious adverse events in each of the studies reviewed, it is noted that animal studies suggest a safer profile with ropivacaine or levobupivacaine than with bupivacaine.

World apheresis registry report.

The establishment of national apheresis registries has been helpful to learn about therapeutic profiles and adverse event incidences. During 2003, the World Apheresis Registry was established and centers from all countries were invited to participate to register their apheresis activities (at www.iml.umu.se/medicin). In this paper, we will report and analyze the first data retrieved from three centers, in 2 European countries, that registered a total of 388 therapeutic apheresis treatments in 122 patients, 95% due to acute indications. Statistical analyses were performed using an independent Student t-test and Fisher's test. A p-value of less than 0.05 was considered significant. Fifty percent of the treated patients were women. The mean age of the patients was 51 years (+/-17, range 16-84) and there was no difference between genders (w 50.4, m 51.6 years). Diagnoses for treatment were mainly neurological and vasculitis. In 63% peripheral access was used with a central double lumen catheter, 22% in the jugular vein, 8% in the subclavian vein and 6% the femoral vein. Significant inter-center differences were seen in regard to the access used. The main technique used was centrifugation for conventional plasma exchange (86%), while other modes were leukapheresis, erythrapheresis, platelet apheresis, LDL-apheresis and adsorption of antibodies. Citrate was the only anticoagulant in 92%. During plasma exchange procedures using centrifugation, replacement was by albumin only (58%) or plasma, the latter often in combination with albumin (42%). Adverse events (AEs) were noted in 11% of the procedures. Patients with hypocalcaemia side effects with tingling sensations were included in those data as mild AE and as moderate AEs if they received calcium (Ca) medication. No patient died due to adverse effects. A mild AE was present in 1.8% and moderate in 8.5%. During two procedures (0.5%), the AE was considered severe and therefore the procedure was interrupted. If those with AEs due to lower calcium were removed from analyses, 6.4% had AEs. Significantly more AEs were found when plasma was used as a replacement fluid (p=0.017, RR 2.05, CI 1.17-3.60). There were no differences in the incidence of AEs between genders. The number of procedures was too small to allow sub analyses of AEs in relation to the diagnoses. Adverse events were not related to the procedure used (p=0.095). Those who received additional Ca infusion during the procedure had no AEs (40 sessions) while the others who received no prophylactic Ca had an AE on 45 occasions (p=0.0141, RR 1.116, CI 1.08-1.15). Data from the registry shows that centers have various approaches to apheresis. One can learn from each other's experience to reduce side effects and improve efficacy. From these data we noted that prophylactic Ca infusion reduced side effects.

Polycystic ovary syndrome (PCOS) is a major hyperandrogenic disorder. Many drugs prescribed specifically to treat PCOS have side effects; however, previous studies suggest that natural therapeutics including botanicals may be less invasive and equally effective for the management of PCOS. In the present study, plants were screened for antiandrogenic activity using the RIKILT yeast Androgen bioAssay (RAA). Selected positive plants were subsequently tested for their efficacy against PCOS induced by estradiol valerate (EV) in rat models. RAA revealed the antiandrogenic property of Nardostachys jatamansi DC (NJ), Tribulus terrestris L. (TT), and Embelia tsjeriam-cottam DC (EJ), whereas Whithania somnifera Dunal (WS), Symplocos racemosa Roxb. (SR), and Helicteres isora L. (HI) exhibited androgenic properties. EJ also exhibited mild androgenic activity and therefore was excluded from further study. EV administration reduced the weight gain and disrupted cyclicity in all rats. NJ and TT extract treatment normalized estrous cyclicity and steroidal hormonal levels and regularized ovarian follicular growth. The in vitro antiandrogenic activity of plant extracts and their positive effects on different parameters of PCOS were proved in vivo.

Hydroxychloroquine in systemic lupus erythematosus (SLE).

PubMed

Ponticelli, C; Moroni, G

2017-03-01

Hydroxychloroquine (HCQ) is an alkalinizing lysosomatropic drug that accumulates in lysosomes where it inhibits some important functions by increasing the pH. HCQ has proved to be effective in a number of autoimmune diseases including systemic lupus erythematosus (SLE). Areas covered: In this review the mechanisms of action, the efficacy, and the safety of HCQ in the management of patients with SLE have been reviewed. HCQ may reduce the risk of flares, allow the reduction of the dosage of steroids, reduce organ damage, and prevent the thrombotic effects of anti-phospholipid antibodies. The drug is generally safe and may be prescribed to pregnant women. However, some cautions are needed to prevent retinopathy, a rare but serious complication of the prolonged use of HCQ. Expert opinion: HCQ may offer several advantages not only in patients with mild SLE but can also exert important beneficial effects in lupus patients with organ involvement and in pregnant women. The drug has a low cost and few side effects. These characteristics should encourage a larger use of HCQ, also in lupus patients with organ involvement.

In heart failure patients, chronic hyperactivation of sympathetic signaling is known to exacerbate cardiac dysfunction. In this study, the cardioprotective effect of vidarabine, an anti-herpes virus agent, which we identified as a cardiac adenylyl cyclase inhibitor, in dogs with pacing-induced dilated cardiomyopathy (DCM) was evaluated. In addition, the adverse effects of vidarabine on basal cardiac function was compared to those of the β-blocker, carvedilol.Methods and Results:Vidarabine and carvedilol attenuated the development of pacing-induced systolic dysfunction significantly and with equal effectiveness. Both agents also inhibited the development of cardiac apoptosis and fibrosis and reduced the Na + -Ca 2+ exchanger-1 protein level in the heart. Importantly, carvedilol significantly enlarged the left ventricle and atrium; vidarabine, in contrast, did not. Vidarabine-treated dogs maintained cardiac response to β-AR stimulation better than carvedilol-treated dogs did. Vidarabine may protect against pacing-induced DCM with less suppression of basal cardiac function than carvedilol in a dog model. (Circ J 2016; 80: 2496-2505).

Tricuspid annuloplasty is increasingly performed during left heart valve surgery, but the long-term clinical outcome postoperatively is not satisfactory. The aim of this study was to determine whether residual pulmonary hypertension (PHT) contributes to the adverse outcome. One-hundred thirty-seven patients (age 61±11 years; men, 30%) who underwent tricuspid annuloplasty during left-side valve surgery were enrolled. The mean pulmonary artery systolic pressure before surgery was 49±13 mm Hg and 32±15 mm Hg following surgery. Patients were divided into 3 groups according to postoperative pulmonary artery systolic pressure: no residual PHT (n=78, 57%), mild residual PHT (n=43, 31%), or significant residual PHT (n=16, 12%). A preoperative larger right ventricular (RV) geometry and tricuspid valve tethering area were associated with mild or significant residual PHT. A total of 24 adverse events (20 heart failures and 4 cardiovascular deaths) occurred during a median follow-up of 25 months. Kaplan-Meier survival curve demonstrated that patients with significant residual PHT had the highest percentage of adverse events followed by those with mild residual PHT. Patients with no residual PHT had a very low risk of adverse events. Multivariable Cox regression analysis revealed that both mild (hazard ratio=4.94; 95% CI =1.34-18.16; P=0.02) and significant residual PHT (hazard ratio=8.67; 95% CI =2.43-30.98; P<0.01) were independent factors associated with adverse events. The present study demonstrated that 43% of patients who underwent tricuspid annuloplasty had residual PHT. The presence of mild or significant residual PHT was associated with adverse events in these patients. © 2016 The Authors.

Emotional disorders are a common outcome from mild traumatic brain injury (TBI) in humans, but their pathophysiological basis is poorly understood. We have developed a mouse model of closed-head blast injury using an air pressure wave delivered to a small area on one side of the cranium, to create mild TBI. We found that 20-psi blasts in 3-month-old C57BL/6 male mice yielded no obvious behavioral or histological evidence of brain injury, while 25–40 psi blasts produced transient anxiety in an open field arena but little histological evidence of brain damage. By contrast, 50–60 psi blasts resulted in anxiety-like behavior in an open field arena that became more evident with time after blast. In additional behavioral tests conducted 2–8 weeks after blast, 50–60 psi mice also demonstrated increased acoustic startle, perseverance of learned fear, and enhanced contextual fear, as well as depression-like behavior and diminished prepulse inhibition. We found no evident cerebral pathology, but did observe scattered axonal degeneration in brain sections from 50 to 60 psi mice 3–8 weeks after blast. Thus, the TBI caused by single 50–60 psi blasts in mice exhibits the minimal neuronal loss coupled to “diffuse” axonal injury characteristic of human mild TBI. A reduction in the abundance of a subpopulation of excitatory projection neurons in basolateral amygdala enriched in Thy1 was, however, observed. The reported link of this neuronal population to fear suppression suggests their damage by mild TBI may contribute to the heightened anxiety and fearfulness observed after blast in our mice. Our overpressure air blast model of concussion in mice will enable further studies of the mechanisms underlying the diverse emotional deficits seen after mild TBI. PMID:24478749

Dupuytren's disease (DD) is a fibroproliferative pathology that affects the palmar aponeurosis causing the development of nodules and collagen cords and the progressive flexion of the fingers. The standard procedure is surgical fasciectomy, followed by high recurrence rates. Collagenase Clostridium histolyticum (CCH) injection represents an innovative noninvasive approach to the treatment of DD. This prospective study was designed to examine the efficacy and safety of CCH injection performed in the outpatient, using local anesthesia. Forty patients [32 metacarpophalangeal (MP), 8 proximal interphalangeal (PIP)] with Dupuytren's contracture of at least 20° for MP joint and any degree for PIP joint were included. The mean age was 66. All joints were treated with a single vial of collagenase injection and manual breaking of the cord 24 h after. All adverse effects (AEs) were monitored. Patients were checked 7, 30, 90, and 180 days after the injection. Primary endpoint was a reduction in digit contracture within 0°-5° of normal extension. Secondary endpoints were the improvement of range of motion, the evaluation of AEs incidence, and cost-effectiveness of collagenase treatment. About 67.5 % of patients obtained a clinical success. At 6 months, a further 7.5% attained the same result. The mean contracture of treated joints was 5.3º for MP and 6.8° for PIP joints. Twenty-three patients had one or more mild-to-moderate side effects. The use of collagenase appears to be an effective and safe method for the treatment of Dupuytren's contracture. Therapeutic success was achieved in a significant percentage of patients. The incidence of side effects was higher, but they were local reactions of short duration. The use of a single collagenase vial in patients treated in day surgery appears more cost-effective than surgery.

Background: Dysmenorrhea has negative effects on women's life. Due to side-effects of chemical drugs, there is growing trend toward herbal medicine. The aim of this study was to assess the effect of Dill compared to mefenamic acid on primary dysmenorrhea. Materials and Methods: This double-blind, randomized, clinical trial study was conducted on 75 single female students between 18 and 28 years old educating in Nursing and Midwifery School and Paramedical Faculty of Qom University of Medical Sciences of Iran in 2011. They were allocated randomly into one of the three groups: In Dill group, they took 1000 mg of Dill powder q12h for 5 days from 2 days before the beginning of menstruation for two cycles. Other groups received 250 mg mefenamic acid or 500 mg starch capsule as placebo, respectively. Dysmenorrhea severity was determined by a verbal multidimensional scoring system and a visual analog scale (VAS). Students with mild dysmenorrhea were excluded. Data were analyzed by SPSS using the descriptive statistic, paired-samples t-test, Wilcoxon signed-rank test, Mann-Whitney test, and Kruskal-Wallis test. Results: There were no significant differences between three groups for demographic or descriptive variables. Comprising the VAS showed that the participants of Dill and mefenamic acid groups had lower significant pain in the 1st and the 2nd months after treatment, whereas in the placebo group this was only significant in the 2nd month (P < 0.05). Conclusion: Dill was as effective as mefenamic acid in reducing the pain severity in primary dysmenorrhea. Further studies regarding side-effects of Dill and its interactivity are recommended.

Atopic dermatitis (AD) is a chronic inflammatory skin disease that causes dry skin and functional disruption of the skin barrier. AD is often accompanied by allergic inflammation. AD patient suffer from heavy itching, and their quality of life is severely affected. Some pharmaceuticals for AD have some side effects such as skin atrophy. So it is necessary to develop mild solutions such as food ingredients without side effects. There are various causes of AD. It is especially induced by immunological imbalances such as IFN-γ reduction. IFN-γ has an important role in regulating IgE, which can cause an allergy reaction. NC/Nga mice develop AD and IgE hyperproduction. In a previous study, we revealed that administration of polysaccharide from black currant ( R. nigrum ) has an effect on immunomodulation. It induces IFN-γ production from myeloid dendritic cells. We named this polysaccharide cassis polysaccharide (CAPS). In this report, we studied the effect of administering CAPS on atopic dermatitis in NC/Nga mice. Thirty NC/Nga mice that developed symptoms of atopic dermatitis were used. We divided them into three groups (control, CAPS administration 12 mg/kg/day, CAPS administration 60 mg/kg/day). For 4 weeks, we evaluated clinical score, serum IgE levels, gene expression of spleen, and skin pathology. We revealed that CAPS administration improves atopic dermatitis symptoms. We also found that CAPS administration suppresses IgE hyperproduction and induces IFN-γ gene transcription in the spleen. Finally, we confirmed that CAPS administration suppresses mast cell migration to epidermal skin. These results indicated that CAPS has an effect on AD.

To evaluate the effect of Diane-35, alone or in combination with orlistat or metformin, on androgen and body fat percentage parameters in Chinese overweight and obese polycystic ovary syndrome (PCOS) patients with insulin resistance. A total of 240 PCOS women were randomly allocated to receive Diane-35 alone (D group), Diane-35 plus orlistat (DO group), Diane-35 plus metformin (DM group), or Diane-35 plus orlistat plus metformin (DOM group). Serum TT, DHEA-S, androstenedione, SHBG, FT, FAI, body fat, and body fat percentage were assessed at baseline and after 12 weeks of treatment. Significant changes in serum TT, SHBG, and FAI were observed in all treatment groups compared with baseline. DHEA-S and androstenedione significantly decreased in the DO, DM, and DOM groups after treatment. FT only significantly decreased in the DOM group. Body fat and body fat percentage significantly decreased in the DO and DOM groups. Compared with the D group, DHEA-S significantly decreased in the DO, DM, and DOM groups (F = 4.081, p = 0.008); SHBG significantly increased in the DOM group (F = 3.019, p = 0.031); and FAI significantly decreased in the DO group (χ 2  = 12.578, p = 0.006). There were significant differences between groups in body fat percentage (χ 2  = 23.590, p < 0.001). Side-effects were less with orlistat than metformin. Diane-35 in combination with orlistat or metformin is more effective in reducing androgen than Diane-35 alone. Orlistat is more effective in reducing body fat percentage than metformin. In addition, orlistat has mild side-effects and is better tolerated compared with metformin.

Background and Aims Rhamnogalacturonan II (RGII) is a structurally complex pectic sub-domain composed of more than 12 different sugars and 20 different linkages distributed in five side chains along a homogalacturonan backbone. Although RGII has long been described as highly conserved over plant evolution, recent studies have revealed variations in the structure of the polysaccharide. This study examines the fine structure variability of RGII in wine, focusing on the side chains A and B obtained after sequential mild acid hydrolysis. Specifically, this study aims to differentiate intrinsic structural variations in these RGII side chains from structural variations due to acid hydrolysis. Methods RGII from wine (Vitis vinifera Merlot) was sequentially hydrolysed with trifluoroacetic acid (TFA) and the hydrolysis products were separated by anion-exchange chromatography (AEC). AEC fractions or total hydrolysates were analysed by MALDI-TOF mass spectrometry. Key Results The optimal conditions to recover non-degraded side chain B, side chain A and RGII backbone were 0·1 m TFA at 40 °C for 16 h, 0·48 m TFA at 40 °C for 16 h (or 0·1 m TFA at 60 °C for 8 h) and 0·1 m TFA at 60 °C for 16 h, respectively. Side chain B was particularly prone to acid degradation. Side chain A and the RGII GalA backbone were partly degraded by 0·1 m TFA at 80 °C for 1–4 h. AEC allowed separation of side chain B, methyl-esterified side chain A and non-methyl-esterified side chain A. The structure of side chain A and the GalA backbone were highly variable. Conclusions Several modifications to the RGII structure of wine were identified. The observed dearabinosylation and deacetylation were primarily the consequence of acidic treatment, while variation in methyl-esterification, methyl-ether linkages and oxidation reflect natural diversity. The physiological significance of this variability, however, remains to be determined. PMID:24908680

Parkinson's disease (PD) is the second most common neurodegenerative disorder, but its underlying cause remains unknown. Although recent studies using PD-related neurotoxin MPP + suggest autophagy involvement in the pathogenesis of PD, the effect of MPP + on autophagic processes under mild exposure, which mimics the slow progressive nature of PD, remains largely unclear. We examined the effect of mild MPP + exposure (10 and 200 μM for 48 h), which induces a more slowly developing cell death, on autophagic processes and the mechanistic differences with acute MPP + toxicity (2.5 and 5 mM for 24 h). In SH-SY5Y cells, mild MPP + exposure predominantly inhibited autophagosome degradation, whereas acute MPP + exposure inhibited both autophagosome degradation and basal autophagy. Mild MPP + exposure reduced lysosomal hydrolase cathepsin D activity without changing lysosomal acidity, whereas acute exposure decreased lysosomal density. Lysosome biogenesis enhancers trehalose and rapamycin partially alleviated mild MPP + exposure induced impaired autophagosome degradation and cell death, but did not prevent the pathogenic response to acute MPP + exposure, suggesting irreversible lysosomal damage. We demonstrated impaired autophagic degradation by MPP + exposure and mechanistic differences between mild and acute MPP + toxicities. Mild MPP + toxicity impaired autophagosome degradation through novel lysosomal acidity-independent mechanisms. Sustained mild lysosomal damage may contribute to PD. We examined the effects of MPP + on autophagic processes under mild exposure, which mimics the slow progressive nature of Parkinson's disease, in SH-SY5Y cells. This study demonstrated impaired autophagic degradation through a reduction in lysosomal cathepsin D activity without altering lysosomal acidity by mild MPP + exposure. Mechanistic differences between acute and mild MPP + toxicity were also observed. Sustained mild damage of lysosome may be an underlying cause of Parkinson's disease.

1988-01-01

In a prospective study, 85 patients with chronic pancreatitis have been subjected to evaluation by morphologic analysis (endoscopic retrograde cholangiopancreatography), by exocrine function tests (bentiromide PABA and 72-hour fecal fat testing), and by endocrine function tests (oral glucose tolerance test and fat-stimulated release of pancreatic polypeptide). All patients were graded on a five-point system, with 1 point assessed for an abnormal result in each of the five tests performed. Zero score denoted mild disease; 1-2 points signaled moderate disease; and 3-5 points indicated severe disease. In 68 patients, both an initial and late (mean follow-up period of 14 months) evaluation were performed. Forty-one patients underwent modified Puestow side-to-side Roux-en-Y pancreaticojejunostomy. The Puestow procedure alone was performed in 18 patients. Eight patients also had drainage of pseudocysts, seven also had a biliary bypass, and eight had pseudocyst drainage plus bypass, in addition to the Puestow. There were no deaths. Of the 68 patients who were studied twice, 30 had operations and 38 did not. None of the patients with severe disease improved their grade during follow-up. Of 24 patients who did not undergo operation, 17 (71%) who were graded mild/moderate progressed to a severe grade at follow-up. By contrast, only three of the 19 patients operated on (16%) and who were initially graded as mild/moderate progressed to severe disease at follow-up testing. More than 75% of all of the patients had a history of weight loss. Twenty-six of 30 patients operated on (87%) (all of whom had lost weight before surgery) gained a mean 4.2 kg (range 1.4-2.7 kg) after surgery, compared with no significant weight change (range -3.6-2.7 kg) among patients not operated on. These findings support a policy of early operation for chronic pancreatitis, perhaps even in the absence of disabling abdominal pain. PMID:3421756

The aim of this study was to evaluate the effects of a traditional Chinese herbal medicine, dai-kenchu-to (DKT), on obstructive bowel diseases in children. We have treated 46 pediatric patients with various obstructive bowel diseases with DKT: six patients with postoperative ileus, 12 with large abdominal surgery (including three neonates), one with ano-rectal anomaly, three with Hirschsprung's disease, two with functional bowel obstructions, one with SMA syndrome, and 21 patients with chronic constipation. DKT (0.1-0.15 g/kg) was mixed with 5-10 ml of warm water, and was given orally two to three times a day. DKT was effective for 39 patients (85%) and their clinical symptoms improved. DKT was ineffective in seven patients: two with postoperative ileus, two with Hirschsprung's disease, and three with chronic constipation. DKT had mild but significant effects for various obstructive bowel diseases in children, while no side effects were encountered. Our current strategy for pediatric patients with obstructive bowel disease is to use DKT first and then test its efficacy. If DKT is effective, the regimen is continued. However, in cases where DKT is not effective, we will consider laparotomy or will further investigate the illness.

A 16 1/2-year-old phenotypic female had primary amenorrhea, mild mental retardation, radioulnar synostosis, and other minor anomalies. Chromosome constitution of leukocytes and skin fibroblasts was 48,XXXX. Plasma levels of gonadotropins were increased, and those of estrogens, decreased consistent with ovarian failure. Laparoscopy showed a small midline uterus, and 2 fallopian tubes, and fimbriae. Neither ovaries nor gonadal streaks were seen on either side. This patient appears to represent the first instance of 48,XXXX aneuploidy with documented absence of ovaries.

A 24-year-old Ugandan woman was referred for a neurology opinion after complaining of a year long history of right-sided retro-orbital stabbing pain. Brain imaging revealed a coincidental 3 mm left ophthalmic artery aneurysm. Marfanoid habitus was noted; after further investigations she was diagnosed with mild aortic root dilatation, subtle lens dislocation and Marfan syndrome. Her symptoms were secondary to temporomandibular joint dysfunction, an under-recognised complication of Marfan syndrome. Her ophthalmic artery aneurysm is likely to be a coincidental finding.

A case of denosumab-induced hypocalcaemia in a patient with non-metastatic prostate cancer and renal impairment.

PubMed

Blackley, S; Anderson, K; Berg, J

2015-01-01

Denosumab is an emerging new treatment for osteoporosis in postmenopausal women and men with non-metastatic prostate cancer. It is largely used by specialists as an alternative treatment in patients with contraindications to traditional, more commonly used drugs such as bisphosphonates. One important side effect is hypocalcaemia, which may be life threatening. The risk of this is increased in renal impairment, mainly if eGFR < 30 ml/min/1.73m(2), and is exacerbated by vitamin D insufficiency. This is a case study of prolonged symptomatic hypocalcaemia after a single dose of denosumab in a patient with non-metastatic prostate cancer and moderate renal impairment (eGFR 40 ml/min/1.73m(2)). The patient presented with acute confusion, muscle cramps and myoclonic jerks 5 weeks after treatment. This case demonstrates the need to be aware of adverse effects of denosumab in mild-moderate renal impairment and the need to monitor calcium levels pre- and post-treatment.

Tinea pedis is a common skin disease affecting most of the population during their lifetime. Topical and systemic treatments give only temporary relief. To evaluate the efficacy and safety of a new topical treatment for moderate-to-severe tinea pedis. Fifty patients suffering from tinea pedis were treated in two stages: the active stage--single use of the novel topical solution for 45 min and novel cream twice weekly for 4 weeks; the preventive stage--cream application once weekly for 10 months. Forty-five patients completed the active stage and achieved 76% cure rate. The medication was well tolerated; one patient dropped from the study because of very mild irritation. No other topical or systemic side effects were noted. Another five patients were lost to follow-up during the preventive stage. The total cure rate after the preventive stage was 70%. This novel treatment was found to be effective, well tolerated and safe in the treatment of moderate and severe tinea pedis during the active and the preventive stages.

The use of an "unnatural" prostaglandin in the termination of pregnancy.

1971-04-01

An unnatural prostaglandin (PG) (prepared by biosynthesis using the method described by Vonkerman et al.) was used to terminate midtrimester pregnancy in 3 primiparous patients aged 21-24. The PG was administered intravenously using a Palmer slow infusion pump. The patients were monitored continuously with particular attention given to pulse, respiration, blood pressure, uterine contractions and cervical dilatation. All 3 cases successfully aborted. Effective infusion rate was similar to that of PGE1 and PGE2 (5-6 mcg/minute) and side effects were trivial (minimal skin flushing, vomiting, mild urticarial reaction). 2 of the patients aborted 8 and 22 hours after infusion stopped without being conscious of continuing uterine activity; the 3rd patient necessitated infusion on the 2nd day and exhibited increased response to the infusion; however, the PG supply was exhausted and syntocinon infusion facilitated the complete abortion. This study shows that this synthetic prostaglandin containing an uneven number of carbon atoms is pharmacologically active and can induce contractions in the intact human pregnant uterus.

A newly designed curcumin mimic library (11a-11k) with 2-ethylamino groups in a chalcone structure and variously substituted triazole groups as side chains was synthesized using the Huisgen 1,3-cycloaddition reaction between various alkynes (a-k) and an intermediate (10), with CuSO4 and sodium ascorbate in a solution mixture of chloroform, ethanol, and water (5:3:1) at room temperature for 5h. In the lactate dehydrogenase (LDH) release assay involving co-treatment with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) and/or synthetic curcumin derivatives using TRAIL-resistant human CRT-MG astroglioma cells, the novel curcumin mimic library was found to effectively stimulate the cytotoxicity of TRAIL, causing mild cytotoxicity when administered alone. In particular, 11a and 11j are promising candidates for TRAIL-sensitizers with potential use in combination chemotherapy for brain tumors. Copyright © 2014 Elsevier Ltd. All rights reserved.

Antipsychotic drugs frequently cause amenorrhoea and galactorrhoea. Jasmine flowers used topically were as effective as oral Bromocriptine in suppressing puerperal lactation. This study aims to evaluate the efficacy and safety of intranasal jasmine flower extract (JFE) to reduce prolactin levels of patients on stable doses of antipsychotic drugs. This is a randomized, double blind, crossover clinical trial. An aqueous-ethanol extract of jasmine flowers was prepared and used as nasal drops. A decrease in serum prolactin of ≥25 ng/mL was considered a significant response. Ten out of 35 women had a significant drop in the serum prolactin while on the JFE. The non-responders to JFE were on higher doses of antipsychotic drugs. The main side effect was a transient and mild burning sensation in the nose. A cost analysis favoured JFE over dopamine agonists. JFE contains a prolactin-lowering substance which needs further characterisation. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Clinical relevance of cannabis tolerance and dependence.

PubMed

Jones, R T; Benowitz, N L; Herning, R I

1981-01-01

Psychoactive drugs are often widely used before tolerance and dependence is fully appreciated. Tolerance to cannabis-induced cardiovascular and autonomic changes, decreased intraocular pressure, sleep and sleep EEG, mood and behavioral changes is acquired and, to a great degree, lost rapidly with optimal conditions. Mechanisms appear more functional than metabolic. Acquisition rate depends on dose and dose schedule. Dependence, manifested by withdrawal symptoms after as little as 7 days of THC administration, is characterized by irritability, restlessness, insomnia, anorexia, nausea, sweating, salivation, increased body temperature, altered sleep and waking EEG, tremor, and weight loss. Mild and transient in the 120 subjects studied, the syndrome was similar to sedative drug withdrawal. Tolerance to drug side effects can be useful. Tolerance to therapeutic effects or target symptoms poses problems. Clinical significance of dependence is difficult to assess since drug-seeking behavior has many determinants. Cannabis-induced super sensitivity should be considered wherever chronic drug administration is anticipated in conditions like epilepsy, glaucoma or chronic pain. Cannabis pharmacology suggests ways of minimizing tolerance and dependence problems.

Objective Actinic cheilitis (AC) is a precancerous lesion of the lip vermillion caused by prolonged exposure to ultraviolet light. The aim of this study was to evaluate the effect of 3% diclofenac in 2.5% hyaluronic acid gel in the treatment of AC. Methods Thirty-four patients with chronic AC were treated twice a day with topical diclofenac during a period of 30 to 180 days. The individuals were followed up every 15 days by means of clinical examination and digital photographic documentation. Results Of the 27 patients that completed the study, 12 (44%) showed complete remission of the whitish plaques and exfoliative areas, and 15 (56%) had partial remission of the clinical picture of cheilitis. The latter group was submitted to excision of the leukoplakic areas which diagnosis varied from mild to moderate epithelial dysplasia. Conclusion The results suggest a promising role for diclofenac in hyaluronic acid gel in the treatment of AC. This treatment has the advantages of not being invasive and showing few side effects.

The use of double J catheters is usual in urologist's daily practice. The indication can be divided in prophylactic or therapeutic. Prophylactically, they prevent complications derived from endourological procedures, such as ureteral lesion or obstructive uropathy secondary to residual lithiasis or edema. Therapeutically, they treat obstructive uropathy of many different pathologies, either in an emergency setting or scheduled, such as lithiasis, stenosis, extrinsic compression of any nature or urinary tract tumors among others. Although they add clear benefits in both cases, they are not free from side effects. The most frequent symptoms they cause are: voiding urgency and increase in voiding frequency, macroscopic hematuria and suprapubic and lumbar pain. The physiopathological mechanism is explained by a mechanical and inflammatory effect or due to vesicoureteral reflux depending on the symptom. This causes patient's quality of life disturbance that may vary from mild degree to very severe. Thus, several strategies have emerged with the aim of diminishing or palliate the intensity of such symptoms: alpha-blocker drugs, design modifications or reduction of their use.

This study performed microwave-assisted acid pretreatment on pure lignin. The effects of microwave temperature, microwave time, and hydrochloric acid concentration on characteristics and pyrolysis behavior of lignin were examined. Results of ultimate analysis revealed better properties of all pretreated samples than those of raw lignin. Fourier transform infrared spectroscopy analysis showed breakage of βO4 bond and aliphatic side chain, decrease in OH groups, and formation of CO groups in pretreatment. Microwave temperature exerted more significant influence on lignin structure. Thermal stability of treated lignin was improved and insensitive to short microwave time and acid concentration under mild conditions. Resulting from improved alkyl-phenols and decreased alkoxy-phenols, microwave-assisted acid pretreatment of lignin yielded bio-oil with excellent quality. Total yield of phenols in pyrolysis vapors (200 °C) improved to 14.15%, whereas that of guaiacols decreased to 22.36%. This study shows that microwave-assisted acid pretreatment is a promising technology for lignin conversion. Copyright © 2017 Elsevier Ltd. All rights reserved.

1996-12-01

This study was undertaken in 102 adult patients to evaluate the safety and efficacy of intravenous (i.v.) midazolam in the setting of bone marrow aspiration and trephine biopsy (BMAT). Combined local anaesthetic (LA) and sedation was used in 87% of patients and 13% received LA alone. Amnesia occurred in all sedated patients with only 9% experiencing a mild degree of post-procedure pain. This contrasted sharply with the non-sedated group, in whom 85% had intense pain during the biopsy followed by protracted local discomfort in approximately 54%. Drowsiness and some psychomotor impairment were the only notable sedation-related side-effects in approximately 20%. None required assisted ventilation. There was a resounding patient preference for BMAT with sedation. Considering the ease of use, safety and efficacy of i.v. midazolam, the availability of flumazenil as a reversal agent and the undoubted positive effects on quality of life, we would advocate using it in BMAT provided that there were no contraindications.

Objective In this study, we aimed to examine the relationship between chin deviation and the positional and morphological features of the mandible and to determine the factors that contributed to chin deviation in individuals with a unilateral cleft lip and palate (UCLP). Methods Cone-beam computed tomography (CBCT) images of 28 adults with UCLP were analyzed in this study. Segmented three-dimensional temporomandibular fossa and mandible images were reconstructed, and angular, linear, and volumetric parameters were measured. Results For all 28 individuals, the chin was found to deviate to the cleft side by 1.59 mm. Moreover, among these 28 individuals, only 7 showed distinct (more than 4 mm) chin deviation, which was toward the cleft side. Compared to the non-cleft side, the mandibular body length, frontal ramal inclination, and vertical position of the condyle were lower and inclination of the temporomandibular fossa was steeper on the cleft side. Furthermore, the differences in inclination of the temporomandibular fossa, mandibular body length, ramus length, and condylar volume ratio (non-deviated/deviated) were positively correlated with chin deviation. Conclusions UCLP individuals show mild chin deviation to the cleft side. Statistical differences were noted in the parameters that represented positional and morphological asymmetries of the mandible and temporomandibular fossa; however, these differences were too small to indicate clinical significance.

To study the efficacy and tolerability of add-on levetiracetam in children and adolescents with refractory epilepsy. In this prospective multi-centre, open-label, add-on study, 33 children aged 4-16 years (median 8.5 years) with epilepsy refractory to at least two antiepileptic drugs were treated with levetiracetam in addition to their present treatment regimen with a follow-up of 26 weeks. The starting dose of 10 mg/kg/day was increased with 2-week steps of 10 mg/kg/day, if necessary, up to a maximum dose of 60 mg/kg/day. Retention rate was 69.7% after 26 weeks on a median levetiracetam dosage of 22 mg/kg/day. Four children dropped-out because levetiracetam was ineffective, four because seizure frequency increased and/or seizures became more severe, and two because they developed aggressive behaviour. Compared to their baseline seizure frequency, 13 children (39.4%) had a >50% seizure reduction 12 weeks after initiation of levetiracetam, and 17 children (51.5%) at 26 weeks. At 26 weeks, nine children (27.3%) had been seizure-free for at least the last 4 weeks, terminal remission ranged from 0 to 187 days (mean 46 days). Levetiracetam was effective in both partial and primary generalized seizures, but had most effect in partial seizures. Most reported side effects were hyperactivity (48.5%), somnolence (36.4%), irritability (33.3%) and aggressive behaviour (27.3%). Severity of most side effects was mild. Five children had a serious adverse event, which all concerned hospital admissions that were not related to levetiracetam use. Levetiracetam proved to be an effective and well-tolerated add-on treatment in this group of children with refractory epilepsy.

1997-01-01

The effect of metergoline, a 5-hydroxytryptamine (serotonin) antagonist, on the plasma concentrations of prolactin in overtly pseudopregnant Afghan hounds and on the clinical symptoms of overt pseudopregnancy were studied. Plasma concentrations of prolactin and progesterone were determined in six Afghan hounds with signs of overt pseudopregnancy for 2-3 weeks and in three Afghan hounds that were not pseudopregnant at the time of blood sampling. In the overtly pseudopregnant bitches the plasma concentrations of prolactin before treatment (35.5 +/- 8.5 micrograms l-1) were significantly higher than the plasma concentrations of prolactin of the three bitches that were not pseudopregnant (6.3 +/- 0.5 micrograms l-1); the latter values were similar to those of non-pseudopregnant beagle bitches during the total luteal phase. The six pseudopregnant Afghan hounds were treated for 10 days with the antiserotoninergic drug metergoline. At 2 h after the onset of treatment with metergoline, the mean plasma concentration of prolactin had decreased to 10.8 +/- 2.9 micrograms l-1. The plasma concentrations of prolactin continued to decline to 5.4 +/- 1.0 micrograms l-1 at 4 h and to 1.0 +/- 0.1 microgram l-1 during treatment days 3-10. Signs of pseudopregnancy, such as swelling of the mammary glands and digging, decreased during the treatment period. The treatment was associated with mild behavioural side effects such as whimpering and aggressiveness. These side effects are probably not related to suppression of prolactin but are due to a direct effect on serotoninergic pathways in the brain. It is concluded that high plasma concentrations of prolactin are associated with the development and maintenance of pseudopregnancy. The serotonin antagonist metergoline strongly suppresses plasma concentrations of prolactin in pseudopregnant dogs and decreases the clinical signs of pseudopregnancy.

Plasma concentrations of prolactin and progesterone were determined in six Afghan hounds with signs of overt pseudopregnancy for 2-3 weeks and in three Afghan hounds that were not pseudopregnant at the time of blood sampling. In the overtly pseudopregnant bitches the plasma concentrations of prolactin before treatment (35.5 +/- 8.5 micrograms l-1) were significantly higher than the plasma concentrations of prolactin of the three bitches that were not pseudopregnant (6.3 +/- 0.5 micrograms l-1); the latter values were similar to those of non-psueodopregnant beagle bitches during the total luteal phase. The six pseudopregnant Afghan hounds were treated for 10 days with the antiserotoninergic drug metergoline. At 2 h after the onset of treatment with metergoline, the mean plasma concentration of prolactin had decreased to 10.8 +/- 2.9 micrograms l-1. The plasma concentrations of prolactin continued to decline to 5.4 +/- 1.0 micrograms l-1 at 4 h and to 1.0 +/- 0.1 microgram l-1 during treatment days 3-10. Signs of pseudopregnancy, such as swelling of the mammary glands and digging, decreased during the treatment period. The treatment was associated with mild behavioural side effects such as whimpering and aggressiveness. These side effects are probably not related to suppression of prolactin but are due to a direct effect on serotoninergic pathways in the brain. It is concluded that high plasma concentrations of prolactin are associated with the development and maintenance of pseudopregnancy. The serotonin antagonist metergoline strongly suppresses plasma concentration of prolactine in pseudopregnant dogs and decreases the clinical signs of pseudopregnancy.

This post hoc meta-analysis evaluated the efficacy and safety of desvenlafaxine 50 and 100 mg versus placebo across age groups and severity of depression at baseline in patients with major depressive disorder. Data from placebo and desvenlafaxine 50-mg and 100-mg dose arms were pooled from 9 short-term, placebo-controlled, major depressive disorder studies (N = 4279). Effects of age (18-40 years, >40 to <55 years, 55-<65 years, and ≥65 years) and baseline depression severity (mild, 17-item Hamilton Rating Scale for Depression total score [HAM-D17] ≤18; moderate, HAM-D17 >18 to <25; severe, HAM-D17 ≥25) on desvenlafaxine efficacy were assessed using analysis of covariance for continuous end points and logistic regression for categorical end points. Desvenlafaxine-treated (50 or 100 mg/d) patients had significantly (P < 0.05, 2-sided) greater improvement in most measures of depression and function compared with placebo for patients 18 to 40 years, older than 40 to younger than 55 years, and 55 to younger than 65 years, with no significant evidence of an effect of age. Desvenlafaxine significantly improved most measures of depression and function in moderately and severely depressed patients. There was a significant baseline severity by treatment interaction for HAM-D17 total score only (P = 0.027), with a larger treatment effect for the severely depressed group. Desvenlafaxine significantly improved depressive symptoms in patients younger than 65 years and in patients with moderate or severe baseline depression. Sample sizes were not adequate to assess desvenlafaxine efficacy in patients 65 years or older or with mild baseline depression.

Atopic dermatitis (AD) is most prevalent in areas of reduced skin barrier reserve, like face and neck, especially in children. Treatment with topical corticosteroids (TCS) is limited due to heightened risk of treatment-associated side-effects, thus necessitating alternative AD therapies. The primary study objective was to determine the efficacy of pimecrolimus cream 1% in children with mild-moderate facial AD dependent on/intolerant of TCS. Secondary objectives included effects on overall Eczema Area and Severity Index (EASI), head/neck EASI, pruritus severity and time to clearance of facial AD. A multicentre, double-blind (DB) study of < or = 6 weeks, followed by a 6-week, open-label (OL) phase was conducted. Two hundred patients (aged 2-11 years) were randomized 1:1 to pimecrolimus cream 1% (n = 99) or vehicle (n = 101) twice daily until clearance of facial AD or for a maximum of 6 weeks (DB phase). Sixteen patients receiving vehicle were allowed to switch to the OL phase at day 22. Significantly more pimecrolimus-treated vs. vehicle-treated patients were cleared/almost cleared of facial AD (Investigators' Global Assessment 0/1): 74.5% vs. 51.0%, P < 0.001 (day 43) [57.1% vs. 36.0%, P = 0.004 (day 22)]. Median time to clearance was 22.0 vs. 43.0 days (pimecrolimus vs. vehicle, respectively). Statistically significant differences for pimecrolimus vs. vehicle were also seen on head/neck EASI, overall EASI, and head/neck pruritus scores. Adverse events were mainly mild-moderate, occurring with similar frequency in both treatment groups. In children with facial dermatitis intolerant of/dependent on TCS, pimecrolimus cream 1% effectively controls eczema and pruritus and is well tolerated.

Dementia is a large and growing problem but is often not diagnosed in its earlier stages. Screening and earlier treatment could reduce the burden of suffering of this syndrome. To review the evidence of benefits and harms of screening for and earlier treatment of dementia. MEDLINE, PsycINFO, EMBASE, the Cochrane Library, experts, and bibliographies of reviews. The authors developed eight key questions representing a logical chain between screening and improved health outcomes, along with eligibility criteria for admissible evidence for each question. Admissible evidence was obtained by searching the data sources. Two reviewers abstracted relevant information using standardized abstraction forms and graded article quality according to U.S. Preventive Services Task Force criteria. No randomized, controlled trial of screening for dementia has been completed. Brief screening tools can detect some persons with early dementia (positive predictive value < or =50%). Six to 12 months of treatment with cholinesterase inhibitors modestly slows the decline of cognitive and global clinical change scores in some patients with mild to moderate Alzheimer disease. Function is minimally affected, and fewer than 20% of patients stop taking cholinesterase inhibitors because of side effects. Only limited evidence indicates that any other pharmacologic or nonpharmacologic intervention slows decline in persons with early dementia. Although intensive multicomponent caregiver interventions may delay nursing home placement of patients who have caregivers, the relevance of this finding for persons who do not yet have caregivers is uncertain. Other potential benefits and harms of screening have not been studied. Screening tests can detect undiagnosed dementia. In persons with mild to moderate clinically detected Alzheimer disease, cholinesterase inhibitors are somewhat effective in slowing cognitive decline. The effect of cholinesterase inhibitors or other treatments on persons with dementia detected by screening is uncertain.

Over the last years, the introduction of robotic technologies into Parkinson's disease rehabilitation settings has progressed from concept to reality. However, the benefit of robotic training remains elusive. This pilot randomized controlled observer trial is aimed at investigating the feasibility, the effectiveness and the efficacy of new end-effector robot training in people with mild Parkinson's disease. Design. Pilot randomized controlled trial. Robot training was feasible, acceptable, safe, and the participants completed 100% of the prescribed training sessions. A statistically significant improvement in gait index was found in favour of the EG (T0 versus T1). In particular, the statistical analysis of primary outcome (gait speed) using the Friedman test showed statistically significant improvements for the EG (p = 0,0195). The statistical analysis performed by Friedman test of Step length left (p = 0,0195) and right (p = 0,0195) and Stride length left (p = 0,0078) and right (p = 0,0195) showed a significant statistical gain. No statistically significant improvements on the CG were found. Robot training is a feasible and safe form of rehabilitative exercise for cognitively intact people with mild PD. This original approach can contribute to increase a short time lower limb motor recovery in idiopathic PD patients. The focus on the gait recovery is a further characteristic that makes this research relevant to clinical practice. On the whole, the simplicity of treatment, the lack of side effects, and the positive results from patients support the recommendation to extend the use of this treatment. Further investigation regarding the long-time effectiveness of robot training is warranted. ClinicalTrials.gov NCT01668407.

To evaluate the clinical effects of spinal cord stimulation (SCS) to restore cough in subjects with cervical spinal cord injury. Clinical trial assessing the clinical outcomes and side effects associated with the cough system. Outpatient hospital or residence. Subjects (N=9; 8 men, 1 woman) with cervical spinal cord injury. SCS was performed at home by either the subjects themselves or caregivers on a chronic basis and as needed for secretion management. Ease in raising secretions, requirement for trained caregiver support related to secretion management, and incidence of acute respiratory tract infections. The degree of difficulty in raising secretions improved markedly, and the need for alternative methods of secretion removal was virtually eliminated. Subject life quality related to respiratory care improved, with subjects reporting greater control of breathing problems and enhanced mobility. The incidence of acute respiratory tract infections fell from 2.0+/-0.5 to 0.7+/-0.4 events/subject year (P<.01), and mean level of trained caregiver support related to secretion management measured over a 2-week period decreased from 16.9+/-7.9 to 2.1+/-1.6 and 0.4+/-0.3 times/wk (P<.01) at 28 and 40 weeks after implantation of the device, respectively. Three subjects developed mild hemodynamic effects that abated completely with continued SCS. Subjects experienced mild leg jerks during SCS, which were well tolerated. There were no instances of bowel or bladder leakage. Restoration of cough via SCS is safe and efficacious. This method improves life quality and has the potential to reduce the morbidity and mortality associated with recurrent respiratory tract infections in this patient population.

These studies evaluated the safety and efficacy of enteric-coated budesonide for the induction and maintenance of remission of mild-to-moderate Crohn's disease (CD) in children. The consecutive, multicenter, open-label, non-comparative studies enrolled patients aged 6-17 years. In the induction study, patients with active CD of the ileum and/or ascending colon received budesonide 9 mg or 6 mg once daily for 8 weeks; in the maintenance study, patients in remission received budesonide 6 mg once daily for 12 weeks. The primary objective was assessment of safety, including glucocorticosteroid-related side effects and serum cortisol levels. Efficacy was assessed using the Pediatric Crohn's Disease Activity Index (PCDAI), and health-related quality of life (HRQoL) using the IMPACT-III questionnaire. In the induction study (n = 108), most adverse events were related to CD, commonly abdominal pain; possible glucocorticosteroid-related effects included acne and increased appetite but without significant weight gain. Subnormal morning cortisol levels were observed in 32 of 103 patients after 8 weeks. Budesonide reduced disease activity from baseline (mean ± standard deviation, 9.1 ± 8.5 vs. 19.1 ± 10.1, p < .001) with 58.1% of patients reaching remission (PCDAI <10); HRQoL improved (p < .001). In the maintenance study (n = 50), mean disease activity worsened (p = .047) with HRQoL unchanged (p = .33). Budesonide treatment was generally well tolerated, although the potential for adrenal suppression was noted. Budesonide was effective for induction of remission in children with mild-to-moderate CD but not for maintaining remission (ClinicalTrials.gov identifiers: NCT01444092, NCT01453946).

Systemic steroids are the standard treatment for bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic stem cell transplantation (HSCT) despite their poor efficacy and disabling side effects. To evaluate the effectiveness and tolerance of budesonide/formoterol as an alternative treatment for BOS after HSCT. In this randomized, double-blind, placebo-controlled study, we randomly assigned 32 HSCT recipients with mild/severe BOS to receive budesonide/formoterol or placebo for 6 months. The primary outcome was the change in the FEV1 after 1 month of treatment (M1) compared with the baseline value. Patients were unblinded at M1 if there was no improvement in the FEV1. Those who had initially received placebo were switched to budesonide/formoterol. Intention-to-treat analysis was performed to assess the primary outcome. Additional analyses took scheduled treatment contamination into account. At M1, the median FEV1 increased by 260 ml in the budesonide/formoterol arm compared with 5 ml in the placebo arm (P = 0.012). The median increases in the FEV1 at M1 relative to the baseline value for the treated and placebo groups were 13 and 0%, respectively (P = 0.019). Twenty-five patients received budesonide/formoterol during the study. The median difference in the FEV1 between the baseline and after 1 month of treatment for these patients was +240 ml (P = 0.0001). The effect of budesonide/formoterol on the FEV1 was maintained in the 13 patients who completed 6 months of treatment. Budesonide/formoterol administration led to a significant improvement in the FEV1 in patients with mild/severe BOS after allogeneic HSCT.

The inhibitive ability of 2,6-diaminopyridine, tartaric acid and their synergistic effect towards mild steel corrosion in 0.5 M HCl solution was evaluated at various concentrations using potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and weight loss experiments. Corresponding surfaces of mild steel were examined by atomic force microscope (AFM), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS) analysis. The experimental results are in good agreement and reveal a favorable synergistic effect of 2,6-diaminopyridine with tartaric acid, which could protect mild steel from corrosion effectively. Besides, quantum chemical calculations and Monte Carlo simulation were used to clarify the inhibition mechanism of the synergistic effect. PMID:27628901

Bilateral mandibular defects in a male mongrel dog were repaired. On the left side, a free vascularized coccygeal bone graft that included the median caudal artery and caudal vein was used to correct the defect. On the right side, the defect was bridged with a bone plate and screws. For further immobilization, the muzzle was temporarily taped for 3 weeks and a pharyngostomy tube was used for nutritional support. The dog was able to eat dry commercial food satisfactorily within 2 months of surgery despite mild malocclusion. Radiographs taken 2 months and 18 months postoperatively showed bony union with graft hypertrophy in the left mandible, whereas the right mandibular defect showed protracted nonunion. The results indicate that vascularized coccygeal vertebra transfer provides an alternative for the management of canine mandibular defects.

Background Disease modifying drugs help control the course of relapsing remitting multiple sclerosis (RRMS); however, good adherence is needed for long-term outcomes. Objective To evaluate patient adherence to treatment with subcutaneous interferon beta-1a using RebiSmart® and assess injection-site reactions and treatment satisfaction. Methods This prospective, single-arm, open-label, noninterventional multicenter Phase IV trial included disease modifying drug-experienced mobile patients with RRMS. Adherence was measured over 12 weeks. Items 13–23, 35, 37, and 38 of the Multiple Sclerosis Treatment Concerns Questionnaire (injection-site reactions and treatment satisfaction) were recorded at 12 weeks. Results Sixty patients were recruited (mean age 43.7 [±SD 7.9] years; 83% female; mean years since multiple sclerosis diagnosis 6.7 [SD 4.5]). Adherence data were obtained in 54 patients only due to technical problems with six devices. Over 12 weeks, 89% (n=48) of patients had ≥90% adherence to treatment. Most patients experienced mild influenza-like symptoms and injection-site reactions, and global side effects were minimal. Most patients (78%) rated the convenience as the most important aspect of the device, and most experienced no or mild pain. Conclusion RRMS patients treated with subcutaneous interferon beta-1a, administered with RebiSmart, demonstrated generally good adherence, and the treatment was generally well tolerated.

Platelet-rich plasma (PRP) is considered as a growing modality for tissue regeneration and a developing research area for clinicians and researchers. PRP injection treatment provides supraphysiological concentrations of growth factors that may help in accelerated tissue remodeling and regeneration. To evaluate the efficacy and safety of single autologous PRP intradermal injection for treatment of facial wrinkles and for facial rejuvenation. A total of 20 subjects with different types of facial wrinkles were included in this study. All subjects received single PRP intradermal injection and were clinically assessed before and after treatment for a period of 8 weeks using Wrinkle Severity Rating Scale (WSRS), Skin Homogeneity and Texture (SHnT) Scale, Physician Assessment Scale, and Subject Satisfaction Scale. The mean value of WSRS reduced from 2.90 ± 0.91 before treatment to 2.10 ± 0.79 after 8 weeks of treatment. The most significant results were with younger subjects that have mild and moderate wrinkles of the nasolabial folds (NLFs). Fourteen of seventeen subjects with NLFs showed more than 25% improvement in their appearance. Side effects of PRP treatment were minimal to mild and with excellent tolerability. Single PRP intradermal injection is well tolerated and capable of rejuvenating the face and producing a significant correction of wrinkles especially the NLFs. © 2016 Wiley Periodicals, Inc.

Dose escalation in prostate radiotherapy is limited by normal tissue toxicities. The aim of this study was to assess the impact of margin size on tumor control and side effects for intensity-modulated radiation therapy (IMRT) and 3D conformal radiotherapy (3DCRT) treatment plans with increased dose. Eighteen patients with localized prostate cancer were enrolled. 3DCRT and IMRT plans were compared for a variety of margin sizes. A marker detectable on daily portal images was presupposed for narrow margins. Prescribed dose was 82 Gy within 41 fractions to the prostate clinical target volume (CTV). Tumor control probability (TCP) calculations based on themore » Poisson model including the linear quadratic approach were performed. Normal tissue complication probability (NTCP) was calculated for bladder, rectum and femoral heads according to the Lyman-Kutcher-Burman method. All plan types presented essentially identical TCP values and very low NTCP for bladder and femoral heads. Mean doses for these critical structures reached a minimum for IMRT with reduced margins. Two endpoints for rectal complications were analyzed. A marked decrease in NTCP for IMRT plans with narrow margins was seen for mild RTOG grade 2/3 as well as for proctitis/necrosis/stenosis/fistula, for which NTCP <7% was obtained. For equivalent TCP values, sparing of normal tissue was demonstrated with the narrow margin approach. The effect was more pronounced for IMRT than 3DCRT, with respect to NTCP for mild, as well as severe, rectal complications.« less

Inhaled bronchodilator treatment given via the pressurized metered-dose inhaler (pMDI) with spacer has been recommended for an acute asthma treatment. Unfortunately, most of commercially available spacers are at high cost while a do-it-yourself (DIY) spacer has lower cost as it is made from plastic bottle and siphon pump which are inexpensive and easilyfound materials. This study aims to compare treatment response in nebulizer and DIY spacer used for asthmatic children. A prospective, randomized control study was conducted in children aged 1-15 years old hospitalized for mild to moderate asthmatic attack at Thammasat University Hospital between June 2014 and March 2015. The patients were divided into 2 groups, receiving β2-agonist via nebulization and via pMDI with DIY spacer. Their vital signs and oxygen saturation were monitored and asthma scores were also recorded at admission, 24 hours, 48 hours, and before discharge. The satisfaction of equipment use was evaluated employing questionnaires. 40 childrens were enrolled with male at 72.5% and mean age at 3.1±1.6 years old. There was no significant difference in efficacy of β2-agonist among 2 groups when comparing in consideration of vital signs, oximetry, asthma scores and hospital stay. However, there were significantly different on side effect in which the DIY spacer had less tachycardia and agitation. Satisfaction of parents and healthcare workers were higher in DIY spacer. MDI with DIY spacer was able to be used effectively when compared with nebulization to treat mild to moderate acute exacerbations of asthma in children admitted in hospital.

Physical activity: from epidemiological evidence to individualized patient management.

Physical activity (PA), physical fitness (PF), and even a few sedentary behaviors (SB) are strongly and independently linked to improved survival rate. However, key questions remain: what are the physiological interrelationships between SB, PA, and PF? How should we differently emphasize promoting PA, increasing PF with exercise, and decreasing SB among other prevention measures? What are the interrelationships of both PA and SB levels with drug treatment efficacy? To address these questions we developed an integrated patient-centric model combining physiology with epidemiological evidence to characterize the individual risk attached to PA level, PF, and SB. Epidemiological data were collected by extensive literature review. Nine meta-analyses, 198 cohort studies (3.8 million people), and 13 controlled trials were reviewed. 1. A high level of SB induces chronic stress and increases the risk of both chronic disease and mortality. 2. Vigorous PA increases PF and physiological reserve, thereby improving survival rate. This effect is not mediated by improved traditional risk factors. The risk for most individuals is a mix of high SB, low to mild PA, and low to mild PF. This model can improve the individualized prescription of PA modalities. Furthermore, the benefit of treatments such as statins or beta-blockers can be cancelled out if a decrease in PA or an increase in SB is induced by drug related side effects. To improve patient management both types of therapeutic interventions and dose should be carefully chosen for each individual in order to maintain/increase PA level while decreasing SB.

Acne pathogenesis is multifactorial and includes inflammation. Combining active ingredients targeting multiple components of acne pathogenesis may yield optimal outcomes. This study investigates the safety and efficacy of an antioxidant optimized topical salicylic acid (SA) 1.5% cream containing natural skin penetration enhancers in combination with antioxidant activity for treatment of facial acne. A total of 20 patients with facial acne, aged 19-32 years (2 males, 18 females; mean age 26.1 ± 3.2), were enrolled. Patients were treated with topical 1.5% SA cream and instructed to apply the cream as a thin film over the affected area twice daily (in the morning and evening) for 4 weeks. Inflammatory severity, numbers of papules and pustules were evaluated by investigators at day 0 and weekly, and patients ranked their improvement. In all, 95% of patients improved: 20% had complete clearing, 30% had significantly improved, 15% had moderate improvement, 30% had mild improved, and there was no response in 5% of the patients by 4 weeks of treatment. No side effects were observed. This study demonstrates the efficacy and safety of this optimized topical 1.5% SA cream containing natural skin penetration enhancers in combination with antioxidant activity when applied twice daily for the reduction of facial acne; in particular, it is most effective for mild-to-moderate acne. © 2013 John Wiley & Sons A/S.

Review article: uncomplicated diverticular disease of the colon.

2006-05-15

Diverticular disease of the colon is the fifth most important gastrointestinal disease in terms of direct and indirect health care costs in western countries. Uncomplicated diverticular disease is defined as the presence of diverticula in the absence of complications such as perforation, fistula, obstruction and/or bleeding. The distribution of diverticula along the colon varies worldwide being almost always left-sided and directly related to age in western countries and right-sided where diet is rich in fibre. The pathophysiology of diverticular disease is complex and relates to abnormal colonic motility, changes in the colonic wall, chronic mucosal low-grade inflammation, imbalance in colonic microflora and visceral hypersensitivity. Moreover, there can be genetic factors involved in the development of colonic diverticula. The use of non-absorbable antibiotics is the mainstay of therapy in patients with mild to moderate symptoms, and the effect of fibre-supplementation alone does not appear to be significantly different from placebo, although no definite data are available. More recently, alternative treatments have been reported. Mesalazine acts as a local mucosal immunomodulator and has been shown to improve symptoms and prevent recurrence of diverticulitis. In addition, probiotics have also been shown to be beneficial by re-establishing a normal gut microflora. In this study, the current literature on uncomplicated diverticular disease of the colon is reviewed.

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.

Although under discussion, induced hypothermia (IH) is an established therapy for patients with cardiac arrest or traumatic brain injuries. The influences on coagulopathy and bleeding tendency in severely injured patients (SIP) with concomitant traumatic brain injury are most widely unclear. Therefore, the aim of this study was to quantify the effect of mild IH in SIP with concomitant severe traumatic brain injuries on transfusion rate and mortality. In this retrospective multi-centre study, SIP from three European level-1 trauma centres with an ISS ≥16 between 2009 and 2011 were included. At hospital A, patients qualified for IH with age ≤70 years and a severe head injury with an abbreviated injury scale (AIS Head ) of ≥3. IH was defined as target core body temperature of 35 °C. Hypothermic patients were matched with two patients, one from hospital B and one from hospital C using age and AIS Head . The effect of IH on the transfusion rate, complications and mortality was quantified with 95 % confidence intervals (CI). Patients not treated with IH in hospital A and those from hospital B and C, who were not matched, were used to adjust the CI for the effect of inter-hospital therapy protocol differences. Mean age of patients in the IH-group (n = 43) was 35.7 years, mean ISS 30 points and sex distribution showed 83.7 % male. Mean age of matched patients in the normotherm-group (n = 86) was 36.7 years, mean ISS 33 points and there were 75.6 % males. For the hypothermic patients, we pointed out an estimate of mean difference for the number of transfused units of packed red blood cells as well as for mortality which does not indicate a decrease in the benefit gained by hypothermia. It is suggested that hypothermic patients tend to a higher rate of lung failure and thromboembolisms. Though tending to an increased rate of complications, there is no evidence for a difference in both; rate of transfusion and mortality in SIP. Mild IH as an option for severe head injuries seems as well-being practicable in the presence of multiple severe injuries. Further, clinical studies regarding the side effects are necessary.

The leaves of Phaleria nisidai Kaneh. (Thymelaeaceae) are brewed into a tea commonly used as a tonic, strengthening beverage and immune enhancer in Palau, Micronesia. Recently, the leaves of P. nisidai have been shown to contain toxic daphnane diterpene esters which may pose a public health threat to Palauans. This project documents the use frequency, preparation and side effects of P. nisidai. The content of daphnane diterpene esters in aqueous and methanol extracts and infusions prepared by healers in Palau is compared to assess the risk of daphnane ingestion associated with traditional consumption. Quantitative results are correlated with an in vitro assessment of the immunomodulating activity of the extracts. Research participants, comprising traditional healers and laypeople, were interviewed concerning use patterns and side effects of P. nisidai. Several traditional healers prepared and provided boiled tea samples for chemical analysis. Leaves were collected and methanolic and aqueous extractions were prepared in the laboratory. Peripheral blood mononuclear cells (PBMCs) were cultured with various concentrations of methanol and aqueous leaf extracts and their output of IFNγ was measured using ELISA. Cell proliferation was also assessed using the MTT assay. The concentration of selected daphnane diterpene esters in healer-prepared infusions, lab methanol and lab aqueous extracts was quantified using ultraperformance liquid chromatography-mass spectrometry-triple quadrupole detection (UPLC-MS-TQD). Through structured interviews it was determined that P. nisidai tea was used frequently, with many participants drinking it daily. The reported side effects were mild, and with the exception of diarrhea (n=2), no side effect was mentioned more than once. Methanol extracts contained 4.0μg simplexin, 17.6μg acetoxyhuratoxin and 2.3μg huratoxin per g dry leaf material. In traditional water infusions provided by healers and in standardized lab-prepared aqueous extracts all three compounds were below the limit of detection (16.3ng/mL) using our UPLC-MS-TQD method. Methanol and aqueous extracts increased the release of IFNγ by PBMCs (p<0.05); however, methanol extracts were significantly more active than aqueous extracts (p<0.05). Methanol and aqueous extracts significantly increased proliferation of PBMCs, causing at least 60% more cell proliferation than negative control (p<0.05). The presence of daphnane diterpene esters in a frequently consumed traditional beverage was initially viewed as a public health concern, though interview data reveal that Palauans do not observe toxicity or side effects associated with their use of P. nisidai tea. Concurrently, daphnanes are present in methanolic extracts but not detected in aqueous preparations indicating that the traditional method of preparation avoids the extraction of these potentially toxic compounds, while still maintaining immunostimulant activity.

Hyperthermia is an established anti-cancer treatment but is limited by tolerance of adjacent normal tissues. Parenteral administration of gold nanorods (NRs) as a photosensitizer amplifies the effects of hyperthermia treatment while sparing normal tissues. This therapy is well tolerated and has demonstrated anti-tumor effects in mouse models. The purpose of this phase 1 study was to establish the safety and observe the anti-tumor impact of gold NR enhanced (plasmonic) photothermal therapy (PPTT) in client owned canine patients diagnosed with spontaneous neoplasia. Seven dogs underwent gold NR administration and subsequent NIR PPTT. Side effects were mild and limited to local reactions to NIR laser. All of the dogs enrolled in the study experienced stable disease, partial remission or complete remission. The overall response rate (ORR) was 28.6% with partial or complete remission of tumors at study end. PPTT utilizing gold nanorod therapy can be safely administered to canine patients. Further studies are needed to determine the true efficacy in a larger population of canine cancer patients and to and identify those patients most likely to benefit from this therapy.

Antibiotic-associated diarrhea (AAD) is the most frequent side effect of antibiotic therapy. Clinical signs and symptoms comprise mild and self-limiting courses of diarrhea as well as life threatening courses like pseudomembranous colitis or toxic megacolon. Therapy is symptomatic, antidiarrheal drugs like Saccharomyces boulardii are the therapy of choice. Available studies on S. boulardii in the prevention of AAD are presented as a review. In 14 out of 17 studies including 4,627 patients the administration of S. boulardii achieved a protective effect between 43.7% and 87.3%. A meta-analysis (5 studies, 1,076 patients) showed a significant reduction of the risk to develop an AAD from 17.2% to 6.7%,in a furthermeta-analysis (4 studies on eradication of H. pylori, 1,215 patients) the significant reductionwasfrom 12.2% to 5.6%. There is very good evidence for the yeast S. boulardii to be effective in the prevention of AAD especially in hospitalized adults. The simultaneous administration of S. boulardii to antibiotics resulted in a significant reduction to develop AAD by more than half.

The aim of this work was to evaluate in an open, noncomparative study the use of secnidazole in oral suspension given to Venezuelan children infected with Giardia intestinalis, from a community in Carapita, a slum area in Caracas. Seventy children from 2 to 11 years old (38 males and 32 females) were treated with a single oral dose of secnidazole (30 mg/Kg of body weight), after clinical and parasitological evaluation to make the diagnosis of active giardiasis. The effectiveness of treatment was determined by clinical examination and parasitological evaluation of feces samples 15 days after treatment. The results showed 95% of clinical cure with a significant decrease of the frequency of gastrointestinal symptoms. The parasitological cure was 98%, there were 4 failures at the end of treatment. Side effects observed after treatment were of mild intensity, lasting only few hours. These results show that a simple dose of secnidazole in an oral suspension is an effective, safe and well tolerated treatment for giardiasis in children and that this drug may be used as a mass treatment in risk populations.

Café-au-lait macules (CALMs) are light to dark brown macules or patches of increased melanin concentration found along the dermoepidermal junction. Although many attempts to treat CALMs using various kinds of laser/light-based devices have been reported, CALMs remain refractory thereto with high recurrence rates. In this case series, we describe four patients with idiopathic CALMs that were effectively and safely treated with a non-ablative, high-fluenced, Q-switched (QS), 1064-nm neodymium:yttrium aluminum garnet (Nd:YAG) laser. The typical laser parameters for treating CALMs, including a spot size of 7-7.5 mm, a fluence of 2.4-2.5 J/cm 2 , and one to two passes until the appearance of mild erythema, but not petechiae, were utilized in this study over 12-24 treatment sessions at 2-week intervals. We suggest that high-fluenced QS 1064-nm Nd:YAG laser treatment can be used as an effective and alternative treatment modality for CALMs with minimal risk of side effects.

To determine the effects and safety of dioctahedral smectite (DS) on the duration of acute watery diarrhea in children. A Randomized, open labeled, clinical controlled trial in a tertiary care hospital outpatient department (OPD) and emergency department. Participants were one hundred and seventeen children without any chronic illness between 2 and 5 years presenting to OPD, having acute watery diarrhea for <48 h with mild to moderate dehydration, not on antibiotics and requiring oral rehydration therapy. Intervention done was DS with a dose of 1.5 g thrice daily. Freshly dissolved DS in a dose of 1.5 g thrice daily for 5 days significantly shortened the duration of acute watery diarrhea in children aged 2-5 years. There were no adverse effects on the use of DS. DS was acceptable to the children, and its administration was not accompanied with any side effects. DS reduces the duration of diarrhea in Indian children and prevents a prolonged course, and therefore, may consistently reduce the costs in treatment of acute watery diarrhea.

To evaluate the long-term effectiveness of rivastigmine patch or capsule on mild to severe Alzheimer's disease (AD). We performed a meta-analysis of 17 studies regarding the treatment effectiveness of rivastigmine patch or capsule on mild-to-severe AD. Significant difference exists between treatment with rivastigmine patch or capsule and placebo groups (p-value < 0.001). In the Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog) score evaluation, a negative weighted mean difference (WMD) was observed in overall and mild-moderate groups after rivastigmine treatment. And in ADAS-ADL score evaluation, a positive WMD was observed in overall groups after rivastigmine treatment. Moreover, WMD value is lower in patch administration subgroup compared to that of capsule administration subgroup. Rivastigmine treatment shows a positive result of improving the condition of patients with mild-to-severe AD. Patch administration shows a stronger effect on decreasing ADAS-Cog score compared to capsule administration.

Skin toxicity is the main side effect of epidermal growth factor receptor (EGFR) inhibitors, often leading to dose reduction or discontinuation. We hypothesized that phosphatase inhibition in the skin keratinocytes may prevent receptor dephosphorylation caused by EGFR inhibitors and be used as a new potential strategy for the prevention or treatment of this side effect. Menadione (Vitamin K3) was used as the prototype compound to test our hypothesis. HaCat human skin keratinocyte cells and A431 human squamous carcinoma cells were used. EGFR inhibition was measured by Western blotting and immunofluorescence. Phosphatase inhibition and reactive oxygen species (ROS) generation were measured by standard ELISA and fluorescence assays. Menadione caused significant and reversible EGFR activation in a dose-dependent manner starting at nontoxic concentrations. EGFR activation by menadione was associated with reversible protein tyrosine phosphatase inhibition, which seemed to be mediated by ROS generation as exposure to antioxidants prevented both menadione-induced ROS generation and phosphatase inhibition. Short-term coincubation of cells with nontoxic concentrations of menadione and the EGFR inhibitors erlotinib or cetuximab prevented EGFR dephosphorylation. Seventy-two-hour coincubation of cells with the highest nontoxic concentration of menadione and erlotinib provided for a fourfold cell growth inhibitory protection in HaCat human keratinocyte cells. Menadione at nontoxic concentrations causes EGFR activation and prevents EGFR dephosphorylation by erlotinib and cetuximab. This effect seems to be mediated by ROS generation and secondary phosphatase inhibition. Mild oxidative stress in skin keratinocytes by topical menadione may protect the skin from the toxicity secondary to EGFR inhibitors without causing cytotoxicity. ©2011 AACR

Does the cause of the mild traumatic brain injury affect the expectation of persistent postconcussion symptoms and psychological trauma?

PubMed

Sullivan, Karen A; Wade, Christina

2017-05-01

A controlled experiment of the effect of injury cause on expectations of outcome from mild traumatic brain injury (TBI) was conducted. Ninety-three participants were randomly assigned to one of four conditions. The participants read a vignette that described a mild TBI (with fixed injury parameters) from a different cause (sport, domestic assault, fall, or motor vehicle accident). The effect of the manipulation on expectations of persistent postconcussion symptoms and psychological trauma was assessed with standard measures and a novel "threat-to-life" measure. The Kruskal-Wallis H test for group differences revealed a significant but selective effect of group on symptom and trauma outcomes (ŋ 2 s ≥ .10; large effects). Post hoc pairwise tests showed that, in most cases, there was an expectation of a worse outcome following mild TBI from a domestic assault than from the other causes (small-to-medium effects). Expectations were selectively altered by an experimental manipulation of injury cause. Given that expectations of outcome are known to affect mild TBI prognosis, the findings suggest the need for greater attention to injury cause.

Recent advances in topical anesthesia

PubMed Central

2016-01-01

Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream, a mixture of various topical anesthetics, has been reported to be more potent than other anesthetics. Recently, new products with modified ingredients and application methods have been introduced into the market. These products may be used for mild pain during periodontal treatment, such as scaling. Dentists should be aware that topical anesthetics, although rare, might induce allergic reactions or side effects as a result of an overdose. Topical anesthetics are useful aids during dental treatment, as they reduce dental phobia, especially in children, by mitigating discomfort and pain. PMID:28879311

Gorlin-Goltz syndrome is a rare multisystemic disease, characterized by numerous basal cell carcinomas. The ideal approach for patients with the syndrome would be a treatment with a high cure rate, minimal scarring, short healing time and mild side-effects. Electrochemo-therapy is a novel therapeutic option that ablates tumours with electrical current and simultaneously administered anticancer drugs. Three patients with Gorlin-Goltz syndrome were treated with electrochemotherapy using intravenous bleomycin. Clinical response was obtained in 98 (99%) of the lesions, 86 (87%) of them showed complete response. In 2 tumours, regression was confirmed with histological examination. Long-term cosmetic results were excellent. We consider electrochemotherapy to be an additional tool in the therapeutic armamentarium for Gorlin-Goltz syndrome, and suggest using it as early as possible in selected patients to avoid disfiguring scarring.

We report findings for a patient that underwent endobronchial ultrasound (EBUS) guided transbronchial needle aspiration (TBNA) for diagnostic purposes after an abnormal chest CT. The patient initially presented with cough and shortness of breath. Chest CT revealed a 6 cm soft tissue mass with mildly enlarged right hilar lymph nodes (LNs) and a small right sided pleural effusion. Based on these radiologic findings, the patient underwent an EBUS guided FNA of the mass. To our surprise, the mass was hypoechoic by EBUS and on aspiration, the syringe filled with yellow fluid. This finding in combination with a re-review of the CT scans with a special focus on the Hounsfield Units of the lesion confirmed the diagnosis of a mediastinal bronchogenic cyst. This case demonstrates the role of Hounsfield units in analyzing mediastinal masses and highlights the effectiveness of EBUS guided TBNA in diagnosis and treatment of bronchogenic cysts.

Abstract Small doses of mizoribine (MZR) were administered to five rheumatoid arthritis (RA) patients on hemodialysis (HD). A maintenance dose of 25 mg or less was administered either once per day or once following HD. The Lansbury activity index improved in all patients. The blood concentrations of MZR before and after HD were 0.33-1.79 μg/ml and 0-0.93 μg/ml, respectively. Hence, the rate of elimination by HD ranged from 50.3% to 83.4%. As far as side effects were concerned, alopecia was seen in two patients, and one patient developed shingles. However, the severity of these symptoms was mild and, after discontinuing or reducing the dose of MZR for a certain period of time, we were able to continue its administration. These findings suggest that the long-term administration of MZR is a useful treatment for RA patients on HD.

To report the short- and long-term complications and clinical outcomes of a cohort of dogs managed for gastric dilatation-volvulus using a modified right-sided tube gastropexy technique. Retrospective case series. Of 31 dogs treated, 29 (93·5%) had an excellent short-term outcome, and gastric dilatation-volvulus did not recur in any dog. Twenty-six dogs (84%) were initially fed via the gastrostomy tube postoperatively; three (9·7%) suffered a major complication including septic peritonitis (n=1), and premature tube removal (n=2). Fourteen dogs (45·1%) had minor complications including mild, self-limiting discharge from the stoma site in 13. Modified tube gastropexy using a mushroom-tipped silicone catheter is an effective and safe surgical method for the management of gastric dilatation-volvulus. The gastrostomy tube allowed early enteral feeding and easy administration of medications, including gastroprotectants. © 2017 British Small Animal Veterinary Association.

2015-05-11

Fabrication of hydrophilic polymeric nanofibers that undergo facile and selective functionalization through metal catalyst-free Diels-Alder "click" reaction in aqueous environment is outlined. Electrospinning of copolymers containing an electron-rich furan moiety, hydrophobic methyl methacrylate units and hydrophilic poly(ethylene glycol)s as side chains provide specifically functionalizable yet antibiofouling fibers that remain stable in aqueous media due to appropriate hydrophobic hydrophilic balance. Efficient functionalization of these nanofibers is accomplished through the Diels-Alder reaction by exposing them to maleimide-containing molecules and ligands. Diels-Alder conjugation based functionalization is demonstrated through attachment of fluorescein-maleimide and a maleimide tethered biotin ligand. Biotinylated nanofibers were utilized to mediate immobilization of the protein streptavidin, as well as streptavidin coated quantum dots. Facile fabrication from readily available polymers and their effective functionalization under mild and reagent-free conditions in aqueous media make these "clickable" nanofibers attractive candidates as functionalizable scaffolds for various biomedical applications.

The authors describe a case of L-asparaginase induced intracranial thrombosis and subsequent haemorrhage in a newly diagnosed 30-year-old man with acute lymphoblastic leukaemia who was successfully managed by surgical intervention. At presentation, he had a Glasgow Coma Score of 7/15, was aphasic and had dense right hemiplegia. Neuroimaging revealed an acute anterior left middle cerebral artery infarct with parenchymal haemorrhagic conversion, mass effect and subfalcine herniation. He subsequently underwent left frontal craniotomy and evacuation of large frontal haematoma and decompressive craniectomy for cerebral oedema. Six months postoperatively he underwent titanium cranioplasty. He had made good clinical recovery and is currently mobilising independently with mild occasional episodes of expressive dysphasia, difficulty with fine motor movement on the right side, and has remained seizure free. This is the first documented case of L-asparaginase induced haemorrhagic stroke managed by neurosurgical intervention. The authors emphasise the possible role of surgery in managing chemotherapy induced intracranial complications. PMID:22605598

The aim of the present study was to report on adverse events encountered with robotic-assisted treadmill therapy in children and adolescents with gait disorders. Eighty-nine patients who underwent a trial of robotic assisted treadmill therapy in the two participating centres were analysed. Demographic data and safety data of the patients were analysed using descriptive statistics. In 38 (42.7%) out of 89 patients, adverse events were documented. Most commonly, mild skin erythema at the sites of the cuffs of the device and muscle pain were encountered. In five patients (5.6%), open skin lesions (n = 2), joint pain (n = 2) or tendinopathy (n = 1) limited the continuation of the therapy with the Lokomat. No severe side-effects emerged. Robotic assisted treadmill therapy is a safe method to enable longer periods of gait therapy in children and adolescents with gait disorders.

1987-11-01

An elderly, mildly demented, hypertensive male patient developed hypersomnolence on administration of propranolol for treatment of hypertension; no other cause for hypersomnolence was detected. Upon replacement of propranolol with atenolol, he felt better but continued to be quite somnolent. When atenolol was discontinued, he reported to have lack of sleep. On readministration of subtherapeutic doses of the same beta-adrenergic blocking agents, he once again experienced excessive sleepiness. By discontinuing beta-blocking agents and introducing captopril, he felt much better, became pleasant and talkative, and blood pressure was well controlled. Beta antagonists are important drugs in the management of many cardiovascular problems. Propranolol, a lipophilic beta-blocking agent, and atenolol, a hydrophilic beta-blocking agent, are two of the major agents currently used clinically in the United States. Numerous neuropsychiatric side-effects of the beta-adrenergic blocking drugs have been reported, but hypersomnolence is not readily recognized as one of them.

The value of oral appliances in the treatment of obstructive sleep apnoea

PubMed Central

Rose, Edmund Clemens

2006-01-01

Oral appliances have long been used to treat snoring and mild to moderate obstructive sleep apnoea. This kind of treatment is considered an alternative, non-invasive treatment option. Mandibular protrusive appliances enlarge and stabilise the oro- and hypo-pharyngeal airway space by advancing the mandible, and stretching the attached soft tissue, in particular the tongue, soft palate, uvula, and the pharyngeal tissues. This article summarises the indications, contraindications, and possible side-effects of using oral appliances. Therapeutic efficacy is influenced by multiple parameters that are clinically difficult to control. One major parameter is the patient`s stomatognathic situation of the patient. Thus oral appliances are restricted to patients whose dental retention is adequate for permanent treatment and who do not suffer from temporomandibular joint dysfunction. Regular follow-up sleep studies and dental evaluations are necessary to ensure adequate permanent treatment. PMID:22073072

Cetuximab And The Head And Neck Squamous Cell Cancer.

The head and neck squamous cell cancer (HNSCC) is the most common type of head and neck cancer (more than 90%), and all over the world more than a half million people have been developing this cancer in the last years. This type of cancer is usually marked by a poor prognosis with a really significant morbidity and mortality. Cetuximab received early favor as an exciting and promising new therapy with relatively mild side effect, and due to this received authorization in the 2004 from the European Medicines Agency (EMA) and in the 2006 from the Food and Drug Association (FDA) for the treatment of patients with squamous cell cancer of the head and neck in combination with radiation therapy for locally advanced disease. In this work we will review the application and the efficacy of the Cetuximab in the treatment of the HNSCC.

The preparation of allylic amines is traditionally accomplished by reaction of amines with reactive electrophiles, such as allylic halides, sulfonates or oxyphosphonium species; such methods involve hazardous reagents, generate stoichiometric waste streams, and often suffer from side-reactions (such as over-alkylation). We report here the first nickel-catalysed direct amination of allyl alcohols which enables allylation of primary, secondary and electron-deficient amines, using an inexpensive Ni(II)-Zn couple, without need for glove-box techniques. Under mild conditions, primary and secondary aliphatic amines react smoothly with a range of allyl alcohols, giving secondary and tertiary amines efficiently. This 'totally catalytic' method can be also applied to electron-deficient nitrogen nucleophiles with effective results; the practicality of the process has been demonstrated in an efficient, gram-scale preparation of the calcium antagonist drug substance flunarizine (Sibelium®). © 2018 WILEY-VCH Verlag GmbH & Co.

We wanted to assess Indian palliative-care nurses and physicians' attitudes toward pain control and palliative sedation. From May to September 2008, we interviewed 14 physicians and 13 nurses working in different palliative-care programs in New Delhi, using a semi-structured questionnaire, and following grounded-theory methodology (Glaser and Strauss). The interviewees did not consider administration of painkillers in large doses an ethical problem, provided the pain killers are properly titrated. Mild palliative sedation was considered acceptable. The interviewees disagreed whether palliative sedation can also be deep and continuous. Arguments mentioned against deep continuous palliative sedation were the conviction that it may cause unacceptable side effects, and impedes basic daily activities and social contacts. A few interviewees said that palliative sedation may hasten death. Due to fears and doubts regarding deep continuous palliative sedation, it may sometimes be too easily discarded as a treatment option for refractory symptoms.

Aims and methodTo develop and pilot a clinician-rated outcome scale to evaluate symptomatic outcomes in liaison psychiatry services. Three hundred and sixty patient contacts with 207 separate individuals were rated using six subscales (mood, psychosis, cognition, substance misuse, mind-body problems and behavioural disturbance) plus two additional items (side-effects of medication and capacity to consent for medical treatment). Each item was rated on a five-point scale from 0 to 5 (nil, mild, moderate, severe and very severe). The liaison outcome measure was acceptable and easy to use. All subscales showed acceptable interrater reliability, with the exception of the mind-body subscale. Overall, the measure appears to show stability and sensitivity to change.Clinical implicationsThe measure provides a useful and robust way to determine symptomatic change in a liaison mental health setting, although the mind-body subscale requires modification.Declaration of interestNone.

Forty patients with classical or definite rheumatoid arthritis in a stage of active disease were treated for two weeks at a spa hotel. The patients were divided into four groups of 10. Group I was treated with daily mud packs, group II with daily hot sulphur baths, group III with a combination of mud packs and hot sulphur baths, and group IV served as a control group. The patients were assessed by a rheumatologist who was blinded to the treatment modalities. Statistically significant improvement for a period of up to three months was observed in the three treatment groups in most of the clinical indices. Improvement in the control group was minor in comparison and not statistically significant. No significant improvement was observed in any of the laboratory variables measured. Except for three mild cases of thermal reaction there were no side effects. PMID:2180388

Tranexamic acid is a novel treatment option for melasma; however, there is no consensus on its use. This systematic review searched major databases for relevant publications to March 2016. Eleven studies with 667 participants were included. Pooled data from tranexamic acid-only observational studies with pre- and post-treatment Melasma Area and Severity Index (MASI) showed a decrease of 1.60 in MASI (95% confidence interval (CI), 1.20-2.00; p<0.001) after treat-ment with tranexamic acid. The addition of tranexamic acid to routine treatment modalities resulted in a further decrease in MASI of 0.94 (95% CI 0.10-1.79; p = 0.03). Side-effects were minor, with a few cases reporting hypo-menorrhoea, mild abdominal discomfort, and transient skin irritation. These results support the efficacy and safety of tranexamic acid, either alone or as an adjuvant to routine treatment modalities for melasma.

Men at risk for paradoxical adipose hyperplasia after cryolipolysis.

Keaney, Terrence C; Naga, Lina I

Cryolipolysis, an aesthetic procedure that reduces adipose tissue by exposure to cold temperature, is generally well tolerated with mild side effects including temporary numbness, erythema, and tenderness. However, as cryolipolysis is gaining popularity and more treatments are being performed, reports of rare adverse events including delayed onset pain and paradoxical adipose hyperplasia (PAH) have been described. Recent studies have suggested that PAH can be more common than expected and have a predilection for males, as a disproportionate number of the cases reported in the literature have occurred in men despite the fact that fewer men are likely to be treated with cryolipolysis. Sexual dimorphism in adipose anatomy may provide insight into the increased susceptibility of men to PAH. Careful patient selection avoiding men with visceral abdominal adipose and firm, nondistensible, fibrous fat may be important to minimize the risk of PAH. © 2016 Wiley Periodicals, Inc.

The ocular perceivers are the most voluntarily accessible organs in terms of location in the body, yet drug distribution to these tissues is one of the most intriguing and challenging endeavors and problematic to the pharmaceutical scientist. The most of ocular diseases are treated with topical application of conventional formulation, i.e. solutions, suspensions and ointment. Typically on installation of these conventional formulations, only <5% of the applied dose penetrates the cornea and reaches intraocular tissues, while a major fraction of the instilled dose is wastage due to the presence of many ocular barriers like external barriers, rapid loss of the instilled solution from the precorneal area and nasolacrimal drainage system. Systemic absorption caused systemic side effects varying from mild to life-threatening events. The main objective of this review is to explore the role of colloidal delivery of drug to minimize the drawbacks associated with them. This review provides an insight into the various constraints associated with ocular drug delivery, summarizes recent findings and applications of colloidal delivery systems, i.e. nanoparticles, nanosuspensions, liposomes, niosomes, dendrimers and contact lenses containing nanoparticles have the capacity to distribute ocular drugs to categorical target sites and hold promise to revolutionize the therapy of many ocular perceiver diseases and minimized the circumscription of conventional delivery. Form the basis of literature review, it has been found that the novel delivery system have greater impact to maximize ocular drug absorption, and minimize systemic absorption and side effects.

Intrinsic imperfections and lack of reliable biomarkers preclude optimal individual dosing of hydrocortisone replacement in adrenal insufficiency (AI). However, the clinical relevance of optimal dosing is exemplified by frequently occurring side effects of overreplacement and the dangers of underreplacement. Cortisol in scalp hair has been identified as a retrospective biomarker for long-term cortisol exposure. We compared hair cortisol concentrations (CORT(hair)) of patients with primary or secondary AI on replacement therapy with those of patient controls with a pituitary disease without AI (PCs) and of healthy controls (HCs). In this cross-sectional study, hair samples and anthropometric data were collected in 132 AI patients (52 males), 42 PCs (11 males), and 195 HCs (90 males). The proximal 3 cm of hair were used. CORT(hair) were measured using an ELISA. CORT(hair) were higher in AI patients than in HCs and PCs (P < .001), and hydrocortisone dose correlated with CORT(hair) (P = .04). Male AI patients demonstrated higher CORT(hair) than female patients (P < .001). AI patients had higher body mass index (BMI) than HCs (P < .001), and BMI correlated with CORT(hair) in the whole sample (P < .001). Physiological hydrocortisone replacement is associated with increased CORT(hair). The association between CORT(hair) and BMI could suggest a mild overtreatment that may lead to adverse anthropomorphic side effects, especially in males. CORT(hair) measurements may be a promising additional tool to monitor cumulative hydrocortisone replacement in AI.

Cannabinoids in health and disease.

Cannabis sativa L. preparations have been used in medicine for millenia. However, concern over the dangers of abuse led to the banning of the medicinal use of marijuana in most countries in the 1930s. Only recently, marijuana and individual natural and synthetic cannabinoid receptor agonists and antagonists, as well as chemically related compounds, whose mechanism of action is still obscure, have come back to being considered of therapeutic value. However, their use is highly restricted. Despite the mild addiction to cannabis and the possible enhancement of addiction to other substances of abuse, when combined with cannabis, the therapeutic value of cannabinoids is too high to be put aside. Numerous diseases, such as anorexia, emesis, pain, inflammation, multiple sclerosis, neurodegenerative disorders (Parkinson's disease, Huntington's disease, Tourette's syndrome, Alzheimer's disease), epilepsy, glaucoma, osteoporosis, schizophrenia, cardiovascular disorders, cancer, obesity, and metabolic syndrome-related disorders, to name just a few, are being treated or have the potential to be treated by cannabinoid agonists/antagonists/cannabinoid-related compounds. In view of the very low toxicity and the generally benign side effects of this group of compounds, neglecting or denying their clinical potential is unacceptable--instead, we need to work on the development of more selective cannabinoid receptor agonists/antagonists and related compounds, as well as on novel drugs of this family with better selectivity, distribution patterns, and pharmacokinetics, and--in cases where it is impossible to separate the desired clinical action and the psychoactivity--just to monitor these side effects carefully.

Neutropenia is a rare side effect of gefitinib and was scarcely reported in many large-scale randomized phase III trials using gefitinib monotherapy as first-line treatment. A 77-year-old female was referred to our institution due to abnormal shadow of the right lung, diagnosed by CT scan and biopsy histopathology as adenocarcinoma of the lung (cT3N1M1b). Mutation analysis with PCR-Invader assay of tumor DNA samples revealed short in-frame deletion in exon 19. Based on the diagnosis, first-line treatment was initiated using oral gefitinib (250 mg, daily). During the initial 27 days of gefitinib therapy, the only side effect was a mild skin rash. After 28 days, there was marked tumor shrinkage, indicative of a partial response to gefitinib; however, grade 4 neutropenia was also detected. The patient was switched to the oral erlotinib monotherapy (150 mg/day) as second-line chemotherapy with careful monitoring of neutropenia. Discontinuation of the gefitinib, without the need for granulocyte colony-stimulating factor support, was successful in allowing the neutrophils and leukocytes counts to recover to normal by day 47. The patient continued oral erlotinib for more than 9 months and there has been no evidence of neutropenia, leukopenia, or disease progression. Clinicians should be aware that gefitinib-induced neutropenia in patients with non-small cell lung cancer can be treated successful by switching to erlotinib. Copyright © 2013 Elsevier Ireland Ltd.

This study compared the efficacy of multimatrix mesalazine 2.4 g/day and 4.8 g/day with controlled-release mesalazine 2.25 g/day. In this multicenter, randomized, double-blind study, 251 patients with mildly to moderately active ulcerative colitis received multimatrix mesalazine 2.4 g/day once daily (Multimatrix-2.4), 4.8 g/day once daily (Multimatrix-4.8), or controlled-release (time-dependent) mesalazine 2.25 g/day 3 times daily (Time-2.25) for 8 weeks. The primary efficacy endpoint was the change in the ulcerative colitis-disease activity index (UC-DAI) score. The mean change in the UC-DAI score and standard deviation in the per protocol set was -1.9±2.5 for Multimatrix-2.4 and -2.4±2.8 for Time-2.25. The difference between Multimatrix-2.4 and Time-2.25 was 0.3 (two-sided 95% confidence interval [CI], -0.5 to 1.1), thus non-inferiority was not demonstrated based on the pre-defined non-inferiority margin (1.0). In the full analysis set, the difference between Multimatrix-4.8 and Time-2.25 was -1.2 (two-sided 95% CI, -2.0 to -0.5), and the mean change in UC-DAI score in the FAS was -3.3 (two-sided 95% CI, -3.9 to -2.8) for Multimatrix-4.8 and -1.9 (two-sided 95% CI, -2.5 to -1.3) for Multimatrix-2.4, indicating that Multimatrix-4.8 was more effective than Time-2.25 and Multimatrix-2.4. There was no difference among the treatment groups in terms of safety. This study showed that the efficacy of multimatrix mesalazine 2.4 g/day was comparable to controlled release mesalazine 2.25 g/day, although non-inferiority was not demonstrated. Importantly, this was the first study to indicate that multimatrix mesalazine 4.8 g/day was more effective than 2.4g/day with no associated safety concerns.

The current study examined different aspects of conceptual implicit memory in patients with mild Alzheimer’s disease (AD). Specifically, we were interested in whether priming of distinctive conceptual features versus general semantic information related to pictures and words would differ for the mild AD patients and healthy older adults. In this study, 14 healthy older adults and 15 patients with mild AD studied both pictures and words followed by an implicit test section, where they were asked about distinctive conceptual or general semantic information related to the items they had previously studied (or novel items) Healthy older adults and patients with mild AD showed both conceptual priming and the picture superiority effect, but the AD patients only showed these effects for the questions focused on the distinctive conceptual information. We found that patients with mild AD showed intact conceptual picture priming in a task that required generating a response (answer) from a cue (question) for cues that focused on distinctive conceptual information. This experiment has helped improve our understanding of both the picture superiority effect and conceptual implicit memory in patients with mild AD in that these findings support the notion that conceptual implicit memory might potentially help to drive familiarity-based recognition in the face of impaired recollection in patients with mild AD.

Removal of unwanted hair is the most popular skin treatment worldwide. Over the past decade, various lasers and light sources for epilation have been advocated for use in an office setting, although most people continue to treat unwanted hair with a variety of temporary physical methods (e.g., waxing, shaving) in a home setting, presumably due to cost and convenience factors. To evaluate the safety and efficacy of a low-energy pulsed-light device intended for home-use hair removal. Twenty women (skin phototypes I-IV) with dark terminal hair in nonfacial sites (axilla, forearms, inguinal region, legs) self-administered three treatments at 2-week intervals using a handheld intense-pulsed-light device. Matched untreated skin sites were also studied. Hair counts and clinical photographs were obtained pretreatment and at 1, 3, and 6 months after the third treatment. Side effects and patient satisfaction scores were recorded. All patients showed a positive clinical response to treatment, with reduction of unwanted hair. No reduction of hair was noted in untreated matched areas. Hair counts were reduced 37.8% to 53.6% 6 months after the three treatments. Skin region influenced clinical response, with lower legs exhibiting greater hair reduction than arms and inguinal and axillary areas. Mild erythema was experienced in 25% of patients, but no other side effects or complications were encountered. Patient satisfaction scores were high, with all patients stating that they would purchase the device for future home use. CONCLUSIONS Low-energy pulsed light can be applied safely and effectively for at-home hair removal in a variety of nonfacial locations and skin phototypes I-IV.

Background Soft tissue injuries commonly present to the emergency department (ED), often with acute pain. They cause significant suffering and morbidity if not adequately treated. Paracetamol and ibuprofen are commonly used analgesics, but it remains unknown if either one or the combination of both is superior for pain control. Objectives To investigate the analgesic effect of paracetamol, ibuprofen and the combination of both in the treatment of soft tissue injury in an ED, and the side effect profile of these drugs. Methods Double-blind, double dummy, placebo-controlled randomised controlled trial. 782 adult patients presenting with soft tissue injury without obvious fractures attending the ED of a university hospital in the New Territories of Hong Kong were recruited. Patients were randomised using a random number table into three parallel arms of paracetamol only, ibuprofen only and a combination of paracetamol and ibuprofen in a 1:1:1 ratio. The primary outcome measure was pain score at rest and on activity in the first 2 hours and first 3 days. Data was analysed on an intention to treat basis. Results There was no statistically significant difference in pain score in the initial two hours between the three groups, and no clinically significant difference in pain score in the first three days. Conclusion There was no difference in analgesic effects or side effects observed using oral paracetamol, ibuprofen or a combination of both in patients with mild to moderate pain after soft tissue injuries attending the ED. Trial registration The study is registered with ClinicalTrials.gov (no. NCT00528658). PMID:29408866
