Background: An impairing preoccupation with a nonexistent or slight defect in appearance is the core symptom of body dysmorphic disorder (ODD), a psychiatric condition common in dermatology settings. Objective: We sought to determine the prevalence of ODD in dermatologic patients, comparing general and cosmetic settings, and describing some demographic and clinical characteristics. Methods: In all, 300 patients were consecutively assessed. Screening and diagnoses were performed with validated instruments plus a best estimate diagnosis procedure. The final sample comprised 150 patients in the cosmetic group, 150 patients in the general dermatology group, and 50 control subjects. Standard statistical analyses were performed (chi(2), nonparametric tests, logistic regression). Results: The current prevalence was higher in the cosmetic group (14.0%) compared with general (6.7%) and control (2.0%) groups. No patient had a previous diagnosis. Frequently the reason for seeking dermatologic treatment was not the main ODD preoccupation. Patients with ODD from the cosmetic group were in general unsatisfied with the results of dermatologic treatments. Limitations: Cross-sectional study conducted in a university hospital is a limitation. It is uncertain if the findings can be generalized. Retrospective data regarding previous treatments are not free from bias. Conclusions: BUD is relatively common in a dermatologic setting, especially among patients seeking cosmetic treatments. These patients have some different features compared with general dermatology patients. Dermatologists should be aware of the clinical characteristics of ODD to identify and refer these patients to mental health professionals. (J Am Acad Dermatol 2010;63:235-43.)

Background Burden-of-illness data, which are often used in setting healthcare policy-spending priorities, are unavailable for mental disorders in most countries. Aims To examine one central aspect of illness burden, the association of serious mental illness with earnings, in the World Health Organization (WHO) World Mental Health (WMH) Surveys. Method The WMH Surveys were carried out in 10 high-income and 9 low- and middle-income countries. The associations of personal earnings with serious mental illness were estimated. Results Respondents with serious mental illness earned on average a third less than median earnings, with no significant between-country differences (chi(2)(9)=5.5-8.1, P=0.5-0.79). These losses are equivalent to 0.3-0.8% of total national earnings. Reduced earnings among those with earnings and the increased probability of not earning are both important components of these associations: Conclusions These results add to a growing body of evidence that mental disorders have high societal costs. Decisions about healthcare resource allocation should take these costs into consideration.

Background: Perioperative complications following robotic-assisted radical prostatectomy (RARP) have been previously reported in recent series. Few studies, however, have used standardized systems to classify surgical complications, and that inconsistency has hampered accurate comparisons between different series or surgical approaches. Objective: To assess trends in the incidence and to classify perioperative surgical complications following RARP in 2500 consecutive patients. Design, setting, and participants: We analyzed 2500 patients who underwent RARP for treatment of clinically localized prostate cancer (PCa) from August 2002 to February 2009. Data were prospectively collected in a customized database and retrospectively analyzed. Intervention: All patients underwent RARP performed by a single surgeon. Measurements: The data were collected prospectively in a customized database. Complications were classified using the Clavien grading system. To evaluate trends regarding complications and radiologic anastomotic leaks, we compared eight groups of 300 patients each, categorized according the surgeon`s experience (number of cases). Results and limitations: Our median operative time was 90 min (interquartile range [IQR]: 75-100 min). The median estimated blood loss was 100 ml (IQR: 100-150 ml). Our conversion rate was 0.08%, comprising two procedures converted to standard laparoscopy due to robot malfunction. One hundred and forty complications were observed in 127 patients (5.08%). The following percentages of patients presented graded complications: grade 1, 2.24%; grade 2, 1.8%; grade 3a, 0.08%; grade 3b, 0.48%; grade 4a, 0.40%. There were no cases of multiple organ dysfunction or death (grades 4b and 5). There were significant decreases in the overall complication rates (p = 0.0034) and in the number of anastomotic leaks (p < 0.001) as the surgeon`s experience increased. Conclusions: RARP is a safe option for treatment of clinically localized PCa, presenting low complication rates in experienced hands. Although the robotic system provides the surgeon with enhanced vision and dexterity, proficiency is only accomplished with consistent surgical volume; complication rates demonstrated a tendency to decrease as the surgeon`s experience increased.

Background: Although depression appears to decrease in late life, this could be due to misattribution of depressive symptoms to physical disorders that increase in late we. Methods: We investigated this issue by studying age differences in co-morbidity of DSM-IV major depressive episodes (MDE) with chronic physical conditions in the WHO World Mental Health (WMH) surveys, a series of community epidemiological surveys of respondents in 10 developed countries (n = 52,485) and 8 developing countries (n = 37,265). MDE and other mental disorders were assessed with the Composite International Diagnostic Interview (CIDI). Organic exclusion rules were not used to avoid inappropriate exclusion of cases with physical co-morbidity. Physical conditions were assessed with a standard chronic conditions checklist. Results: Twelve-month DSM-IV/CIDI MDE was significantly less prevalent among respondents ages 65+ than younger respondents in developed but not developing countries. Prevalence of co-morbid mental disorders generally either decreased or remained stable with age, while co-morbidity of MDE with mental disorders generally increased with age. Prevalence of physical conditions, in comparison, generally increased with age, while co-morbidity of MDE with physical conditions generally decreased with age. Depression treatment was lowest among the elderly in developed and developing countries. Conclusions: The weakening associations between MDE and physical conditions with increasing age argue against the suggestion that the low estimated prevalence of MDE among the elderly is due to increased confounding with physical disorders. Future study is needed to investigate processes that might lead to a decreasing impact of physical illness on depression among the elderly. Depression and Anxiety 27:351-364, 2010.

Purpose: The aim of this study was to investigate the impact of acute PaCO(2) temporal variation on the standard base excess (SBE) value in critically ill patients. Methods: A total of 265 patients were prospectively observed; 158 were allocated to the modeling group, and 107 were allocated to the validation group. Two models were developed in the modeling group (one including and one excluding PaCO(2) as a variable determinant of SBE), and both were tested in the validation group. Results: In the modeling group, the mathematical model including SIDai, SIG, L-lactate, albumin, phosphate, and PaCO(2) had a predictive superiority in comparison with the model without PaCO(2) (R(2) = 0.978 and 0.916, respectively). In the validation group, the results were confirmed with significant F change statistics (R(2) change = 0.059, P < .001) between the model with and without PaCO(2). A high correlation (R = 0.99, P < .001) and agreement (bias = -0.25 mEq/L, limits of agreement 95% = -0.72 to 0.22 mEq/L) were found between the model-predicted SBE value and the SBE calculated using the Van Slyke equation. Conclusions: Acute PaCO(2), temporal variation is related to SBE changes in critically ill patients. (C) 2009 Elsevier Inc. All rights reserved.

Background: The aim of the study was to investigate how perfectionism and sensory phenomena (SP) interact as possible phenotypic components of obsessive-compulsive disorder (OCD). Methods: Forty-seven adult outpatients, meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for OCD, and a control group of 41 community subjects were assessed using the Frost Multidimensional Perfectionism Scale (FM PS), the University of Sao Paulo-Sensory Phenomena Scale, and other standard measures of OCD severity. Results: Three of the FMPS subscales (""concern over mistakes,"" ""doubts about action,"" and ""parental criticism"") were significantly different between OCD patients and control subjects. All subtypes of SP were significantly more frequent and more severe in OCD than in control subjects. The ""incompleteness"" subtype of SP was associated with high scores on all dimensions of the FMPS, whereas the ""just-right"" subtype of SP was only associated with ""doubts about action,"" ""personal standards,"" and ""organization"" subscales of the FMPS. Conclusions: Presence and severity of SP and specific elements of perfectionism clearly distinguish OCD patients from healthy control subjects. Some SP subtypes are associated with specific FPMS subscale scores, whereas others are not. These results emphasize the relevance of assessing different subtypes of perfectionism and SP in OCD patients as important subcomponents of the OCD phenotype. (C) 2009 Elsevier Inc.

Background: Formoterol is a fast-acting, long-acting beta-agonist. Its on-demand use by outpatients has been beneficial in controlling asthma. Objective: To evaluate the efficacy of formoterol as rescue medication for pediatric asthma exacerbation. Methods: A randomized, double-blind study was conducted on parallel groups involving 79 pediatric patients (mean [SD] age, 9.92 [2.5] years) with mild to moderate asthma exacerbations. They were treated with up to 3 doses of formoterol aerolizer, 12 mu g, or terbutaline Turbuhaler, 0.5 mg (dry powder inhalers). Respiratory rate, clinical score, pulse oximetry, and spirometry were analyzed at baseline and 15 minutes after administration of each bronchodilator dose. All the patients received oral prednisolone, 1 mg/kg, at study entry, followed by a single daily dose for 4 days. Forty-one patients were treated with formoterol and 38 with terbutaline. The groups were comparable in age and in severity of asthma exacerbation. Results: Both treatments resulted in similar clinical and functional improvement; 37 patients (47%) required 1 bronchodilator dose. Increases of 19.5% and 1.5.3% occurred in forced expiratory volume in 1 second in the formoterol and terbutaline groups, respectively. Therapeutic failures occurred in 2 patients. No adverse effects were observed. At 1-week follow-up, patients were stable, with pulmonary function close to normal. Conclusion: Formoterol therapy was at least as effective as terbutaline therapy in children and adolescents with mild and moderate asthma exacerbations.

Introduction Reduction of automatic pressure support based on a target respiratory frequency or mandatory rate ventilation (MRV) is available in the Taema-Horus ventilator for the weaning process in the intensive care unit (ICU) setting. We hypothesised that MRV is as effective as manual weaning in post-operative ICU patients. Methods There were 106 patients selected in the postoperative period in a prospective, randomised, controlled protocol. When the patients arrived at the ICU after surgery, they were randomly assigned to either: traditional weaning, consisting of the manual reduction of pressure support every 30 minutes, keeping the respiratory rate/tidal volume (RR/TV) below 80 L until 5 to 7 cmH(2)O of pressure support ventilation (PSV); or automatic weaning, referring to MRV set with a respiratory frequency target of 15 breaths per minute (the ventilator automatically decreased the PSV level by 1 cmH(2)O every four respiratory cycles, if the patient`s RR was less than 15 per minute). The primary endpoint of the study was the duration of the weaning process. Secondary endpoints were levels of pressure support, RR, TV (mL), RR/TV, positive end expiratory pressure levels, FiO(2) and SpO(2) required during the weaning process, the need for reintubation and the need for non-invasive ventilation in the 48 hours after extubation. Results In the intention to treat analysis there were no statistically significant differences between the 53 patients selected for each group regarding gender (p = 0.541), age (p = 0.585) and type of surgery (p = 0.172). Nineteen patients presented complications during the trial (4 in the PSV manual group and 15 in the MRV automatic group, p < 0.05). Nine patients in the automatic group did not adapt to the MRV mode. The mean +/- sd (standard deviation) duration of the weaning process was 221 +/- 192 for the manual group, and 271 +/- 369 minutes for the automatic group (p = 0.375). PSV levels were significantly higher in MRV compared with that of the PSV manual reduction (p < 0.05). Reintubation was not required in either group. Non-invasive ventilation was necessary for two patients, in the manual group after cardiac surgery (p = 0.51). Conclusions The duration of the automatic reduction of pressure support was similar to the manual one in the postoperative period in the ICU, but presented more complications, especially no adaptation to the MRV algorithm.

Background: Patients without adequate abdominal-wall transillumination are at a high risk of developing complications after PEG. Objective: We evaluated the feasibility and utility of EUS to guide PEG in patients lacking abdominal-wall transillumination. Design: Single-center case series. Setting: Tertiary-referral center. Patients: Six patients who lacked adequate abdominal-wall transillumination and 2 patients with a large laparotomy scar deemed to be at high risk of developing complications after PEG. Interventions: Patients underwent EUS-guided PEG and deployment of a standard enteral feeding tube. Main Outcome Measurements: Technical success and complication rates. Results: PEG was Successful Under EUS guidance in 5 of 8 patients. Causes of failure included all inadequate EUS window because of a prior Billroth 1 gastrectomy in one and suspected bowel interposition in 2 patients. There were no complications. Limitations: A small number of patients, uncontrolled study, and short follow-up period. Conclusions: This technique may facilitate deployment of PEG in patients who lack adequate abdominal-wall transillumination.

PURPOSE: To report clinical outcomes of the treatment of ocular Demodex folliculorum with oral ivermectin. DESIGN: Noncomparative, interventional case series. METHODS: Setting. Institutional. Study Population. Twenty-four eyes of 12 patients (3 male and 9 female; mean age +/- standard deviation, 50.4 +/- 21.0 years) with refractory posterior blepharitis with the presence of D. folliculorum in lash samples were enrolled in this study. Intervention. Patients were instructed to take 1 dose of oral ivermectin (200 mu g/kg). All patients were instructed to repeat the treatment after 7 days. Main outcome measures. Tear meniscus height, Schirmer I test results, noninvasive tear film break-up time (BUT), quantification of the absolute number of D. folliculorum found in the lashes, and corneal fluorescein and rose bengal staining scores were obtained from all patients 1 day before and 28 days after treatment. RESULTS: Statistical improvement was observed in the absolute number of D. folliculorum found in the lashes after the treatment with oral ivermectin. Average values of Schirmer I test results and tear film break-up time improved statistically after the treatment of oral ivermectin. No statistical improvement was observed in average lacrimal meniscus height or value of corneal fluorescein and rose bengal staining after treatment with oral ivermectin. CONCLUSIONS: Ivermectin successfully reduced the number of D. folliculorum found in the lashes of patients with refractory blepharitis. Oral ivermectin may be very useful as a complement in the treatment of D. folliculorum infestation with ocular manifestation, especially in cases of unsuccessful treatment related to patient compliance.

Objective: To compare the triggering performance of mid-level ICU mechanical ventilators with a standard ICU mechanical ventilator. Design: Experimental bench study. Setting: The respiratory care laboratory of a university-affiliated teaching hospital. Subject: A computerized mechanical lung model, the IngMar ASL5000. Interventions: Ten mid-level ICU ventilators were compared to an ICU ventilator at two levels of lung model effort, three combinations of respiratory mechanics (normal, COPD and ARDS) and two modes of ventilation, volume and pressure assist/control. A total of 12 conditions were compared. Measurements and main results: Performance varied widely among ventilators. Mean inspiratory trigger time was < 100 ms for only half of the tested ventilators. The mean inspiratory delay time (time from initiation of the breath to return of airway pressure to baseline) was longer than that for the ICU ventilator for all tested ventilators except one. The pressure drop during triggering (Ptrig) was comparable with that of the ICU ventilator for only two ventilators. Expiratory Settling Time (time for pressure to return to baseline) had the greatest variability among ventilators. Conclusions: Triggering differences among these mid-level ICU ventilators and with the ICU ventilator were identified. Some of these ventilators had a much poorer triggering response with high inspiratory effort than the ICU ventilator. These ventilators do not perform as well as ICU ventilators in patients with high ventilatory demand.

Bleeding is not uncommon following endoscopic sphincterotomy. Supra-papillary puncture (SPP) might be safer than standard cannulation (SC) techniques in patients with coagulopathy. The aim of the study was to compare the safety and effectiveness of SPP and SC. This was a prospective case control intervention study. Decompensated cirrhotic patients with coagulopathy and choledocolithiasis underwent SC and SPP methods for biliary access. One hundred five patients (56 [53.3%] men, mean [SD] age 56 [15.8]) underwent ERCP. SC and SPP were performed in 63 and 42 patients, respectively. Biliary access was achieved in 56/63 (89%) and 40/42 (95%) of patients undergoing SC and SPP, respectively (P = 0.13; 95% CI [-0.16; 0.03]). Complications occurred in 10/63 (15.8%) patients undergoing SC and 5/42 (11.9%) SPP (P = 0.28; 95% CI [-0.17, 0.16]). Five (7.9%) and two (3.2%) episodes of post-sphincterotomy bleeding was seen in the SC and SPP groups, respectively (P = 0.36; 95% CI [-0.16, 0.05]). In contrast, three (4.8%) episodes of pancreatitis were seen in the SC and none in the SPP group (P = 0.05; 95% CI [0.001; 0.004]). A cost-effectiveness analysis demonstrated that SPP is an acceptable alternative at an ICER of US$ 5,974.92 per additional successful procedure. SPP is a safe and effective technique for the management of common bile duct stones in decompensated cirrhotic patients. Conditional to the willingness-to-pay and to the local ERCP-related costs, SPP is also a cost-effective alternative to the SC methods. SPP is associated with a lower rate of complications but larger studies to validate these findings are necessary.
