Psoriasis and diabetes: a population-based cross-sectional study

Background Previous reports have shown an association between psoriasis and the metabolic syndrome, but there are only a few studies on the association between psoriasis and diabetes. Objectives To study the association between psoriasis and diabetes. Methods A cross‐sectional study was performed utilizing the database of Clalit Health Services (CHS). Patients who were diagnosed with psoriasis were compared with CHS enrolees without psoriasis regarding the prevalence of diabetes. Patients with diabetes were identified using the CHS chronic diseases registry. Chi‐squared tests were used to compare categorical parameters. Logistic regression models were used for multivariate analyses. Results The study included 16 851 patients with psoriasis and 74 987 subjects without psoriasis (control patients). The proportion of diabetes was significantly higher in patients above 35 years (P < 0.05). The age‐adjusted proportion of diabetes was significantly higher in psoriasis patients as compared to the control group [odds ratio (OR), 1.38, P < 0.05] and was similar in men and women (OR, 1.32, 1.45, respectively). A multivariate logistic regression model showed that psoriasis was significantly associated with diabetes, independently of age and gender (OR, 1.58, P < 0.001). Conclusions Our study supports previous reports of an association between psoriasis and diabetes. Dermatologists taking care of patients with psoriasis should be aware of this association and advise the patients to reduce additional risk factors such as smoking, hypertension or dyslipidemia.     

Parenteral and oral acyclovir for management of varicella pneumonia in pregnancy: a case report with review of literature

Varicella pneumonia is a relatively rare disease in the reproductive-aged woman, but has a reported 41 percent maternal mortality rate in pregnancy. Seventeen cases managed with intraveneous acyclovir are reviewed. We report successful management with the unpublished addition of oral acyclovir to complete antiviral therapy on an outpatient basis.     

Theoretical and methodological considerations in the measurement of spasticity

Purpose: To discuss the measurement of spasticity in the clinical and research environments, make recommendations based on the SPASM reviews of biomechanical, neurophysiological and clinical methods of measuring spasticity and indicate future developments of measurement tools. Method: Using the results of the systematic reviews of the biomechanical, neurophysiological and clinical approaches, methods were evaluated across three dimensions: (1) validity, reliability and sensitivity to change; (2) practical quality such as ease of use and (3) qualities specific to the measurement of spasticity, for example ability to be applied to different muscle groups. Methods were considered in terms of applicability to research and clinical applications. Results: A hierarchy of measurement approaches was identified from highly controlled and more objective (but unrelated to function) to ecologically valid, but less objective and subject to contamination from other variables. The lack of a precise definition of spasticity may account for the problem of developing a valid, reliable and sensitive method of measurement. The reviews have identified that some tests measure spasticity per se, some phenomena associated with spasticity or consequential to it and others the effect of spasticity on activity and participation and independence. Conclusions: Methods appropriate for use in research, particularly into the mechanism of spasticity did not satisfy the needs of the clinician and the need for an objective but clinically applicable tool was identified. A clinical assessment may need to generate more than one 'value' and should include evaluation of other components of the upper motor neurone syndrome. There is therefore a need for standardized protocols for 'best practice' in application of spasticity measurement tools and scales.     

A prospective evaluation of nipple stimulation techniques for contraction stress testing

Nipple stimulation techniques for achieving a contraction stress test were evaluated prospectively in 1271 nipple stimulation contraction stress tests in 753 patients. Success was unrelated to parity, gestational age, or warm, moist towels but was related to the presence of spontaneous prestimulation contractions. Various stimulation techniques were equally successful in achieving a completed test in the presence of prestimulation contractions; however, continuous stimulation was more successful when contractions were absent. Hyperstimulation test results occurred in 21.5% of attempts and increased to 28.8% when bilateral, continuous stimulation was performed.
