Alcohol use disorders in patients with obsessive-compulsive disorder: The importance of appropriate dual-diagnosis

Objective: To evaluate the prevalence and clinical associated factors of alcohol use disorders (AUD) comorbidity in a large clinical sample of patients with obsessive-compulsive disorder (OCD). Methods: A cross-sectional study including 630 DSM-IV OCD patients from seven Brazilian university services, comparing patients with and without AUD comorbidity. The instruments of assessment used were a demographic and clinical questionnaire including evaluation of suicidal thoughts and acts and psychiatric treatment, the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I), the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, the Brown Assessment of Beliefs Scale, the Beck Depression and Anxiety Inventories and the Clinical Global Impression Scale. Current or past alcohol and other psychoactive substances use, abuse and dependence were assessed using the SCID-I (section E) and corroborated by medical and familial history questionnaires. Results: Forty-seven patients (7.5%) presented AUD comorbidity. Compared to OCD patients without this comorbidity they were more likely to be men, to have received previous psychiatric treatment, to present: lifetime suicidal thoughts and attempts and to have higher scores in the hoarding dimension. They also presented higher comorbidity with generalized anxiety and somatization disorders, and compulsive sexual behavior. Substance use was related to the appearance of the first O.C. symptoms and symptom amelioration. Conclusions: Although uncommon among OCD treatment seeking samples, AUD comorbidity has specific clinical features, such as increased risk for suicidality, which deserve special attention from mental health professionals. Future studies focused on the development of specific interventions for these patients are warranted. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

The Use of Smell Identification Tests in the Diagnosis of Parkinson`s Disease in Brazil

Smell identification tests may be of routine clinical value in the differential diagnosis of PD but are subject to cultural variation and have not been systematically evaluated in the Brazilian population. We have applied culturally adapted translations of the University of Pennsylvania 40-item smell identification test (UPSIT-40) and the 16-item identification test from Sniffin` Sticks (SS-16) to nondemented Brazilian PD patients and controls. Pearson`s correlation coefficient between the test scores was 0.76 (95% CI 0.70-0.81, n = 204, P < 0.001). To calculate reliability measures for each test we used the diagnosis (either PD or control) as outcome variable for separate logistic regression analyses using the score in the UPSIT-40 or the SS-16 as a covariate. The SS-16 specificity was 89.0% with a sensitivity of 81.1% (106 PD and 118 controls). The UPSIT-40 specificity was 83.5% and its sensitivity 82.1% (95 PD and 109 controls). Regression curves were used to associate an individual`s smell test score with the probability of belonging to the PD, as opposed to the control group. Our data provide support for the use of the UPSIT-40 and SS-16 to help distinguish early PD from controls. (c) 2008 Movement Disorder Society

Transsphenoidal meningoencephalocele associated with cleft lip and palate: challenges for diagnosis and surgical treatment

The aim of this study was to highlight the challenges for early diagnosis and the difficulties observed in surgical treatment of patients with transsphenoidal meningoencephalocele associated with cleft lip and/or palate. We evaluated six male patients treated over the course of 4 years. Five patients presented encephalic herniation with nonfunctional brain tissue; one of these presented herniation of the pituitary gland and cerebral ventricles. All the patients received surgical treatment for the cleft lip and/or palate. Only one patient underwent repair of the meningoencephalocele, via nasal endoscopy. There were no postprocedural clinical or surgical complications. The tendency is to avoid neurosurgery, opting for periodic follow-up with magnetic resonance imaging. In the presence of cleft palate, palatoplasty is essential to protect the meningoencephalocele.

The Role of Prostate Specific Membrane Antigen and Pepsinogen C Tissue Expression as an Adjunctive Method to Prostate Cancer Diagnosis

Purpose: The diagnosis of prostate cancer in men with persistently increased prostate specific antigen after a negative prostate biopsy has become a great challenge for urologists and pathologists. We analyzed the diagnostic value of 6 genes in the tissue of patients with prostate cancer. Materials and Methods: The study was comprised of 50 patients with localized disease who underwent radical prostatectomy. Gene selection was based on a previous microarray analysis. Among 4,147 genes with different expressions between 2 pools of patients 6 genes (PSMA, TMEFF2, GREB1, TH1L, IgH3 and PGC) were selected. These genes were tested for diagnostic value using the quantitative reverse transcription polymerase chain reaction method. Initially malignant tissue samples from 33 patients were analyzed and in the second part of the study we analyzed benign tissue samples from the other 17 patients with prostate cancer. The control group was comprised of tissue samples of patients with benign prostatic hyperplasia. Results: Analysis of malignant prostatic tissue demonstrated that prostate specific membrane antigen was over expressed (mean 9 times) and pepsinogen C was under expressed (mean 1.3 X 10(-4) times) in all cases compared to benign prostatic hyperplasia. The other 4 tested genes showed a variable expression pattern not allowing for differentiation between benign and malignant cases. When we tested these results in the benign prostate tissues from patients with cancer, pepsinogen C maintained the expression pattern. In terms of prostate specific membrane antigen, despite over expression in most cases (mean 12 times), 2 cases (12%) presented with under expression. Conclusions: Pepsinogen C tissue expression may constitute a powerful adjunctive method to prostate biopsy in the diagnosis of prostate cancer cases.

Breast cancer five-year survival in New South Wales women, 1972 to 1991

This study of breast cancer survival is based on analysis of five-year relative survival of 38 362 cases of invasive breast cancer in New South Wales (NSW) women, incident between 1972 and 1991, with follow-up to 1992, using data from the population-based NSW Central Cancer Registry. Survival was ascertained by matching the registry file of breast cancers against NSW death certificates from 1972 to 1992, mainly by automated probabilistic linkage. Absolute survival of cases was compared with expected survival of age- and period-matched NSW women. Proportional hazard regression analysis was used for examination of the effects on excess mortality of age, period of diagnosis and degree of spread at diagnosis. Relative survival at five years increased from 70 per cent in 1972-1976 to 77 per cent in 1987-1991. Survival improved during the 1970s and in the late 1980s. Regression analysis suggested that part of the improved survival in the late 1980s was due to lesser degree of spread at diagnosis, whereas the improved survival during the 1970s may have been due to treatment. Survival was better for those aged 40-49 years (RR = 0.86) and worse for those aged greater than or equal to 70 years (RR = 1.22) compared with the referent group (60-69 years). Excess mortality was much less for those with invasive localised disease than those with regional spread (RR = 3.1) or metastatic cancer (RR = 15.5) at diagnosis. For the most recent period (1987-1991), relative five-year survival was 90, 70 and 18 per cent, respectively, for the three degree-of-spread categories.

Diagnosis, Assessment, and Treatment of Non-Pulmonary Arterial Hypertension Pulmonary Hypertension

The 4th World Symposium on Pulmonary Hypertension was the first international meeting to focus not only on pulmonary arterial hypertension (PAH) but also on the so-called non-PAH forms of pulmonary hypertension (PH). The term ""non-PAH PH"" summarizes those forms of PH that are found in groups 2 to 5 of the current classification of PH, that is, those forms associated with left heart disease, chronic lung disease, recurrent venous thromboembolism, and other diseases. Many of these forms of PH are much more common than PAH, but all of them have been less well studied, especially in terms of medical therapy. The working group on non-PAH PH focused mainly on 4 conditions: chronic obstructive lung disease, interstitial lung disease, chronic thromboembolic PH, and left heart disease. The medical literature regarding the role of PH in these diseases was reviewed, and recommendations regarding diagnosis and treatment of PH in these conditions are provided. Given the lack of robust clinical trials addressing PH in any of these conditions, it is important to conduct further studies to establish the role of medical therapy in non-PAH PH.

Derivation and external validation of a simple prediction model for the diagnosis of type 2 Diabetes Mellitus in the Brazilian urban population

A risk score model was developed based in a population of 1,224 individuals from the general population without known diabetes aging 35 years or more from an urban Brazilian population sample in order to select individuals who should be screened in subsequent testing and improve the efficacy of public health assurance. External validation was performed in a second, independent, population from a different city ascertained through a similar epidemiological protocol. The risk score was developed by multiple logistic regression and model performance and cutoff values were derived from a receiver operating characteristic curve. Model`s capacity of predicting fasting blood glucose levels was tested analyzing data from a 5-year follow-up protocol conducted in the general population. Items independently and significantly associated with diabetes were age, BMI and known hypertension. Sensitivity, specificity and proportion of further testing necessary for the best cutoff value were 75.9, 66.9 and 37.2%, respectively. External validation confirmed the model`s adequacy (AUC equal to 0.72). Finally, model score was also capable of predicting fasting blood glucose progression in non-diabetic individuals in a 5-year follow-up period. In conclusion, this simple diabetes risk score was able to identify individuals with an increased likelihood of having diabetes and it can be used to stratify subpopulations in which performing of subsequent tests is necessary and probably cost-effective.

Use of SVM Methods with Surface-Based Cortical and Volumetric Subcortical Measurements to Detect Alzheimer`s Disease

Here, we examine morphological changes in cortical thickness of patients with Alzheimer`s disease (AD) using image analysis algorithms for brain structure segmentation and study automatic classification of AD patients using cortical and volumetric data. Cortical thickness of AD patients (n = 14) was measured using MRI cortical surface-based analysis and compared with healthy subjects (n = 20). Data was analyzed using an automated algorithm for tissue segmentation and classification. A Support Vector Machine (SVM) was applied over the volumetric measurements of subcortical and cortical structures to separate AD patients from controls. The group analysis showed cortical thickness reduction in the superior temporal lobe, parahippocampal gyrus, and enthorhinal cortex in both hemispheres. We also found cortical thinning in the isthmus of cingulate gyrus and middle temporal gyrus at the right hemisphere, as well as a reduction of the cortical mantle in areas previously shown to be associated with AD. We also confirmed that automatic classification algorithms (SVM) could be helpful to distinguish AD patients from healthy controls. Moreover, the same areas implicated in the pathogenesis of AD were the main parameters driving the classification algorithm. While the patient sample used in this study was relatively small, we expect that using a database of regional volumes derived from MRI scans of a large number of subjects will increase the SVM power of AD patient identification.

Sonographic Diagnosis of a Ureteral Inguinal Hernia in a Renal Transplant

Complications related to renal transplants have been widely reported in the literature. The most common complications include acute tubular necrosis, rejection, perirenal fluid collections, vascular complications, and urinary tract obstruction, which are promptly identified by imaging studies. Here we report a case of a patient with a rare cause of obstruction: a ureteral inguinal hernia. This is the sixth report of this condition, and, to our knowledge, no previous case has been reported in which sonography played an important role in promptly identifying the underlying condition and allowing additional less hazardous studies, therefore aiding case management.

Accuracy of store-and-forward diagnosis in leproy

Telemedicine might increase the speed of diagnosis for leprosy and reduce the development of disabilities. We compared the accuracy of diagnosis made by telemedicine with that made by in-person examination. The cases were patients with suspected leprosy at eight public health clinics in outlying areas of the city of Sao Paulo. The case history and clinical examination data, and at least two clinical images for each patient, were stored in a web-based system developed for teledermatology. After the examination in the public clinic, patients then attended a teaching hospital for an in-person examination. The benchmark was the clinical examination of two dermatologists at the university hospital. From August 2005 to April 2006, 142 suspected cases of leprosy were forwarded to the website by the doctors at the clinics. Of these, 36 cases were excluded. There was overall agreement in the diagnosis of leprosy in 74% of the 106 remaining cases. The sensitivity was 78% and the specificity was 31%. Although the specificity was low, the study suggests that telemedicine may be a useful low-cost method for obtaining second opinions in programmes to control leprosy.

Breast cancer in Western Australia in 1989 .5. Outcome at 5 years after diagnosis

Background: A follow-up study was undertaken of all Western Australian women who had a new diagnosis of boast cancer during 1989. The aims were to determine survival, frequency of recurrence and quality of life (QoL) of Western Australian women 5 years after a diagnosis of breast cancer; to determine reasons for choice ol rejection of reconstructive surgery in those women treated by mastectomy, and to determine if the choice of lumpectomy or mastectomy affects subsequent QoL. Methods: The vital status as at Ist June 1994 of all 692 women who had a new diagnosis of breast cancer in 1989 was ascertained by electronic linkage to official mortality registrations. A subsample of 215 survivors who had originally been treated by the nine surgeons who had managed 20 or more cases each was sent a reply-paid postal questionnaire asking about follow-up treatment since diagnosis, recurrence of disease, current QoL and attitudes to, and use of, reconstructive surgery. Results: The overall survival rate at 5 years was 80.8% (85.9% and 78.8% for Stage I and II, respectively). Cumulative mortality was 35% lower among the third of patients treated by the nine most active surgeons (14% vs 22%, P < 0.02), but this may be subject to referral bias. The subsample was representative of all surviving cases except for being an average of 2.7 years younger at diagnosis (mean ages 55.2 and 57.9 years). The response rate of the subsample to the postal questionnaire was 78%. Of women who had had a mastectomy. 40% had considered having a reconstruction, but only nine (78%) had undergone this operation. Median QoL on the Rosser scale (maximum = 1.0) was 0.9. QoL was worse for the 23% of patients with a recurrence of breast cancer. Patients treated by breast-conserving surgery showed a trend toward a better QoL compared with those treated by mastectomy. Conclusion: At 5 years after the diagnosis of breast cancer, one in five women had died and an estimated one in four of the survivors had recurrent disease. Quality of life in the remaining patients, half of whom had undergone adjuvant treatment, was very good. These are important baseline data against which to judge the impact of mammographic screening.

Adult starvation and disease-related malnutrition: A proposal for etiology-based diagnosis in the clinical practice setting from the International Consensus Guideline Committee

Background & aims: Multiple definitions for malnutrition syndromes are found in the literature resulting in confusion. Recent evidence suggests that varying degrees of acute or chronic inflammation are key contributing factors in the pathophysiology of malnutrition that is associated with disease or injury. Methods: An International Guideline Committee was constituted to develop a consensus approach to defining malnutrition syndromes for adults in the clinical setting. Consensus was achieved through a series of meetings held at the ASPEN and ESPEN Congresses. Results: It was agreed that an etiology-based approach that incorporates a current understanding of inflammatory response would be most appropriate. The Committee proposes the following nomenclature for nutrition diagnosis in adults in the clinical practice setting. ""Starvation-related malnutrition"", when there is chronic starvation without inflammation, ""chronic disease-related malnutrition"", when inflammation is chronic and of mild to moderate degree, and ""acute disease or injury-related malnutrition"", when inflammation is acute and of severe degree. Conclusions: This commentary is intended to present a simple etiology-based construct for the diagnosis of adult malnutrition in the clinical setting. Development of associated laboratory, functional, food intake, and body weight criteria and their application to routine clinical practice will require validation.
