Antisocial personality disorder, HIV risk behavior and retention in methadone maintenance therapy

In a sample of 55 consecutive methadone maintenance admissions to our clinic, 42% were diagnosed with antisocial personality disorder (ASPD) using the National Institute of Mental Health Diagnostic Interview Schedule NIMH DIS. Individuals with ASPD exhibited greater risk for HIV infection as defined by more sexual contacts, needle use and equipment sharing. Data at 1 year follow-up were obtained on this group of patients. The objective was to compare the ASPD and non-ASPD groups with regards to demographics, drug abuse history, outcome and retention in treatment. There were no significant differences between the groups on any demographic or treatment outcome variables. Survival analysis indicated that there were no group differences in treatment retention. In conclusion, although there were no differences in treatment outcome between ASPD and non-ASPD groups it is possible that ASPD patients who drop out of treatment will be at higher risk for contracting and spreading HIV within the IV drug using population. These data also suggest that in this population the diagnosis of ASPD using primarily behavioral traits as measured in the NIMH-DIS-III, has little utility in predicting treatment outcome.     

162例气管插管患者的气道管理

笔者通过报道162例气管插管患者的气道管理，阐述痰痂形成的原因：(1)气道干燥，湿化不够。(2)吸痰管插入深度不够，吸痰不彻底。管理措施：(1)用金霉素眼膏润滑吸痰管，使之易于插入，保证吸痰管插入深度超过插管远端3-5cm。(2)预防气道干燥，注重湿化效果，重视吸痰环节。认为气囊不需定时放气，只需不定时调整气囊压力。     

überlebensverbesserung eines unizentrischen Gesamtkollektivs aus 20 Jahren

PURPOSE: The development of overall survival of a DOSAK (German-Austrian-Swiss Cooperative Group on tumours of the maxillofacial region) clinic's overall population comprising a time period of more than 20 years (1983-2004) should be assessed. At a cutoff date (January 1st, 1997), a change from a primarily surgically based to a consequent multi-modality treatment regimen was implemented. The periods of time before and after that change should be compared. METHODS AND PATIENTS: The data of the DOSAK registry entries on 1038 patients suffering from primary untreated oral and oropharyngeal carcinomas were updated with respect to follow-up and mortality data to achieve a 100% quality of follow-up. The end point (death) was reached in 67% of the overall population. Statistical analysis was carried out by the Trium Analysis Online corporation, Munich. RESULTS: The portion of female and older tumor patients increased, more than half of all tumor patients were clearly in stage IV of the disease at first referral. The portion of patients operated on persisted approximately (80%), the portion of additional treatment modalities could be increased considerably. The fact of a bony infiltration by the tumor and the operability remained highly significantly relevant for survival in multivariate analysis, despite of multi-modality treatment. The survival rate of the patients remained significantly dependent on the clinical stage of the disease in multivariate analysis but could be improved by 10% in the clinical stages II and III and in the patients who could not be operated on. All in all, the cutoff date was statistically relevant for survival in multivariate analysis, i.[Symbol: see text]e. the change in the treatment regimen had a verifiable positive effect on the survival of a unicentric overall population. CONCLUSION: Survival improvement in an overall population via change in treatment strategy is possible in relatively short time; the clinical stages II and III and the non-operable patients have the greatest benefit from a multi-modality treatment.     

Clinical aspects and immune reactions in sarcoidosis*

Introduction: Sarcoidosis is a granulomatous disorder of unknown aetiology, affecting young adults and frequently involving the lungs. Objective: The aim of the present review was to give an overview of the clinical aspects in sarcoidosis. Results: The majority of patients recover, but some develop a chronic disease that may result in fibrosis and respiratory failure. Besides the lungs, peripheral lymph nodes, the skin, the liver and the eyes are commonly affected as well. The genetic background, as well as environmental factors, is of importance for developing sarcoidosis. The incidence varies in different populations, in the Nordic countries approximately with 20/100 000 new patients yearly. Sarcoidosis is diagnosed when clinical and radiological findings are supported by histological evidence in the form of non‐caseating epithelioid cell granulomas, and when other causes of these features are excluded. Patients in need of treatment are usually treated with corticosteroids, topically or as oral steroids. A clinical effect of immunomodulatory drugs blocking tumour necrosis factor (TNF)α has been suggested from several case reports, while two controlled studies showed only minor effects; however, with a tendency to a more pronounced effect on patients with a more severe disease. The immune response in sarcoidosis, with a typical accumulation of CD4+ T‐cells to the lungs, indicate the existence of specific antigens in this disease. Recently, antigens derived from infectious agents such as Mycobacteria and Proprionibacterium acnes have come into focus. Lymphocyte populations with immunoregulatory functions have recently been investigated and seem to be dysfunctional in sarcoidosis, opening the possibility of developing new treatment strategies in this disease. Conclusion: Recent technical developments have provided better tools, enabling detailed and more thorough analyses of the inflammatory process in sarcoidosis. Please cite this paper as: Grunewald J.

Predicting the experience of dentinal caries or restorative dental treatment in adolescents using D1 and D3 visual caries assessments

Standardised epidemiological caries assessments used in oral health surveys have been shown to be poor at predicting whether a tooth surface will be treated restoratively when a patient visits a dentist. However, it has been argued that oral health surveys may be more relevant in determining needs at the level of an individual or groups of individuals. The objective of this study was to determine the discriminatory power of visual caries assessments at two thresholds (D₁ & D₃) in adolescents of average age 12.1 years to predict experience of dentinal caries 3 years later or the experience of restorative treatment (not re‐treatment) during the 3‐year period. The data was derived from a prospective 3‐year longitudinal study in which the dental care provided by 41 dentists for 403 adolescents was monitored. Dental caries experience was monitored by annual standardised assessments of caries undertaken by a single trained examiner. ROC analysis showed that caries assessed visually at the D₁ threshold in 12‐year‐olds was a better predictor (P < 0.001) of experiencing some dentinal caries after 3 years (Az = 0.781) than was caries assessed visually at D₃ threshold in 12‐year‐olds (Az = 0.670). Assessing caries visually at either the D₁ or the D₃ threshold had no discriminatory power for predicting whether an individual would experience some restorative treatment during the ensuing 3‐year period (Az for D₁ = 0.507; Az for D₃ = 0.518).     

ZOON''S VULVITIS

Zoon's vulvitis is reported in a 37 year old woman. Although this condition is very uncommon, diagonisis was definite on histopathological features. Treatment has failed to relieve severe discomfort which has been the main symptom.
