Relapsing eosinophilic perimyositis

Relapsing eosinophilic perimyositis is a rare entity. Only 11 cases have been reported in the literature. We describe a patient with relapsing myopathy, peripheral blood eosinophilia and cutaneous manifestations, who had histopathological features of eosinophilic perimysial inflammation. His disease responded to moderate doses of glucocorticosteroids, and pursued an apparently benign course. Serum levels of eosinophilic cationic protein correlate with disease activity, and may be helpful in monitoring treatment. The features of this case are compared with those of other hypereosinophilic syndromes. It appears to be part of the spectrum of eosinophilic myositis.     

Self-help group participation among substance use disorder patients with posttraumatic stress disorder

Debate has ensued about whether substance use disorder (SUD) patients with comorbid posttraumatic stress disorder (PTSD) participate in and benefit from 12-step groups. One hundred fifty-nine SUD-PTSD and 1,429 SUD-only male patients were compared on participation in 12-step activities following an index episode of treatment. Twelve-step participation was similar for SUD patients with and without PTSD. PTSD patients with worldviews (e.g., holding disease model beliefs) that more closely matched 12-step philosophy participated more in 12-step activities. Although greater participation was associated with better concurrent functioning, participation did not prospectively predict outcomes after case mix adjustment. An exception was that greater participation predicted decreased distress among PTSD patients whose identity was more consistent with 12-step philosophy. In summary, PTSD patients participate in and benefit from 12-step participation; continuing involvement may be necessary to maintain positive benefits.     

Preventive services use among women seen by gynecologists, general medical physicians, or both

OBJECTIVE: To estimate how preventive services and counseling differ for women seen by general medical physicians and gynecologists, and whether seeing both types of physicians had a greater impact on delivery of gender-specific and gender-neutral preventive care than by either type of physician alone. METHODS: Using data from the 2000 National Health Interview Survey, we studied the association of provider type with Pap tests, tobacco use screening, and exercise and diet counseling among women 18-64 years (n=7,317), and these services along with clinical breast examinations, mammograms, and colon cancer screening among women aged 50-64 years (n=1,551). We modeled care using multivariable logistic regression and used propensity score techniques to limit selection bias from choice of provider. RESULTS: In the study sample, 15% were seen by general medical physicians, 62% by gynecologists, and 23% by both. Overall rates of gender-specific services (Pap test, clinical breast examination, mammography) were high (88-95%), whereas gender-neutral services were low (23-53%). Patients of gynecologists only were more likely to have Pap tests (adjusted relative risk [RR] 1.26, 95% confidence interval [CI] 1.24-1.27), tobacco use screening (adjusted RR 1.08, 95% CI 1.02-1.14), mammography (adjusted RR 1.25, 95% CI 1.20-1.28), and clinical breast examination (adjusted RR 1.25, 95% CI 1.19-1.29). In general, combined gynecologist and general care did not increase the likelihood of preventive care. Propensity score analyses confirmed these results. CONCLUSION: Patients of gynecologists receive more preventive services compared with patients of general medical physicians, although rates of gender-neutral services were low regardless of provider type. These findings validate gynecologists' roles as providers of basic preventive care services but demonstrate that considerable room exists to improve delivery of preventive care to women.     

Extending the similarities subtest of the WAIS for increased validity

Departures from standard administration of intelligence tests that raise scores are meaningless unless increased validity is achieved. One hundred and two Ss were administered the Similarities subtest and two predictor measures were derived: the Regular score, and the Extended score which represented the best of several answers given to a particular item. The criterion measures were three SAT scores, the GPA, and a Vocabulary test. Results showed that not only was the Extended score uniformly higher than the Regular score, it was far superior in predicting the various criteria. As such, the Extended score seems to qualify as a good measure of „potential intelligence.”︁ The superiority of the Extended score seemed mainly due to its effectiveness in extracting a greater number of maximum, 2-point answers from the Ss.     

Spina bifida and pediatric cancers

Abstract

Spina bifida has been reported to co-occur with pediatric cancer, but comprehensive evaluations remained elusive. We investigated this co-occurrence in two large, population-based studies in Taiwan (N?=?1900 cancer cases, 2,077,137 controls) and Denmark (N?=?5508 cases, 137,700 controls). Analyses in Denmark were restricted to the period before prenatal diagnostics became available (2004) and pregnancy terminations of fetuses with birth defects became more common. Using national patient and cancer registries, we linked spina bifida and cancer diagnoses among cases and non-cases. The risk of spina bifida among all cancer cases was increased and similar in Denmark [odds ratio (OR)=8.4, 95% confidence interval (CI) 5.1-13.8] and Taiwan (OR = 8.5, 95% CI 4.0-17.8), particularly for central nervous system (CNS) tumors (Denmark: OR = 16.3, 95% CI 8.1-33.0; Taiwan: OR = 26.6, 95% CI 8.5, 83.1), including benign CNS tumors (Denmark: OR = 41.5, 95% CI 21.2, 81.4). These findings suggest the need for comprehensive investigation of shared risk factors in the link between spina bifida and pediatric cancer.     

Contact transscleral retinopexy using a sapphire crystal probe

To examine the laser-tissue interactions for contact transscleral irradiation, argon and CW Nd: YAG light was delivered through a synthetic sapphire crystal which was held in direct conjunctival contact perpendicular to the peripheral retina. The threshold for retinal whitening was 0.5 J in the rabbit, 1.0–1.5J in the monkey, and 1.0–4.0 J in human eyes. Histologic examination of the acute injury and at 2 days, 1, 3, 6, and 12 weeks, showed coagulative lesions centered around the pigmented layers in the rabbit. While severe chorioretinal disruption and hemorrhage did occur depending on species, energy level, and probe location, no scleral perforation was noted at any setting. These preliminary studies suggest that transscleral contact lasers may be used safely in clinical situations where selective ablation of the peripheral retina or pigmented tissues is the primary objective.Presented at the Association for Research and Vision and Ophthalmology, Sarasota, Florida, 5 May 1987     

Gianotti-Crosti syndrome: a study of 26 cases

We have studied 26 patients presenting with a symmetrical papular or papulovesicular acrolocated eruption of more than 10 days duration. Mean age at onset was 2 years (range 10 months to 5.75 years). Lymphadenopathy was noted in eight cases, and hepatomegaly in one case. In 12 cases, histopathology and direct immunofluorescence were non-contributory. Cytolytic hepatitis occurred in one case and was associated with HBs antigenemia. A history of recent immunization was given in two cases. There was serological evidence of recent Epstein-Barr virus infection in seven out of 13 cases tested. Coxsackie B viruses were isolated from three patients, and cytomegalovirus was probably associated with the syndrome in one case. We conclude that the Gianotti-Crosti syndrome is not rare in France, and that non-hepatitis B virus (HBV)-associated cases are more frequent than the classical HBV-associated papular acrodermatitis of childhood.
