Adenocarcinoma arising in a chondroid syringoma of vulva.

Chondroid syringoma of the vulva is an extremely rare tumor. Of the previously reported cases, only one was clinically malignant. The authors describe a case of chondroid syringoma of the right labium majus from which arose a papillary adenocarcinoma. A right inguinal lymph node was replaced with metastatic adenocarcinoma.     

Low Serum Retinol Is Associated with Increased Severity of Measles in New York City Children

Children with no known prior vitamin A deficiency exhibited a significant decline in their serum retinol levels during the acute phase of measles. This decline in circulating retinol was associated with increased duration of fever, higher hospitalization rates, and decreased antibody titers.     

Perceptions of Parenting and Depression-Proneness in the Offspring: Dysfunctional Attitudes as a Mediating Mechanism

This research attempted to clarifythe mechanismthrough which dysfunctional parenting leads todepression in the offspring. Consistent with theorizingbyBeck (1967), we tested a three-stage causal pathway wherein dysfunctional parenting should giverise to dysfunctional attitudes in the offspring which,in turn, should give rise to depression-proneness in theoffspring. Another objective of this study was to further delineate the types of parentingbehaviors that give rise to dysfunctional attitudes inthe offspring. To this end, a large sample of collegestudents (N = 246) completed measures assessing four parenting dimensions (i.e., low care,overprotection, perfectionistic expectations, andcriticalness) as well as measures assessingdysfunctional attitudes, general depression-proneness,and current depression. Support for the depressogenic effects of allfour parenting dimensions was obtained in that eachparenting dimension correlated significantly withdysfunctional attitudes and depression tendencies in the offspring. Moreover, path analyses supportedBeck's three-stage causal model with perfectionistic andcritical parenting playing a particularly prominentrole. Last, after controlling for current depression, the partial correlations among the variables inthe three-stage model remained significant, suggestingthat the present findings were not simply the result ofa mood congruency effect. These findings illuminate additional parenting behaviors that can havedepressogenic effects and indicate that these parentingbehaviors exert their effects, at least in part, by wayof instilling dysfunctional attitudes in the offspring.     

Longitudinal predictors of continued tobacco use among patients diagnosed with cancer

Even though continued smoking by cancer patients adversely affects survival and quality of life, about one third of patients who smoked prior to their diagnosis continue to smoke after their diagnosis. The implementation of smoking cessation treatments for cancer patients has been slowed by the lack of data on correlates of tobacco use in this population. Thus, this longitudinal study assessed demographic, medical, addiction, and psychological predictors of tobacco use among 74 head, neck, and lung cancer patients. Multivariable binary logistic regression analyses, with outcome categorized as smoker or nonsmoker, indicated that the likelihoodthat patients would be a smoker was associated with lower levels of perceived risk and a higher level of quitting cons. Multivariable nominal logistic regression, with outcome classified as continuous smoker, continuous quitter, relapser, or follow-up quitter, indicated that: (a) patients categorized as continuous smokers reported significantly lower quitting self-efficacy than follow-up quitters and continuous quitters, (b) relapsers reported a significantly lower level of quitting self-efficacy than either follow-up quitters or continuous quitters, and (c) continuous smokers exhibited a significantly lower level of risk perceptions than continuous abstainers. These findings can be useful for the development and evaluation of treatments to promote smoking cessation among cancer patients. Support for this study was provided by National Institutes of Health Grants CA57708, CA06927, CA88610, CA95678, and CA76644.     

An Improved Method of Removing Polyurethane Foam-Covered Gel Prostheses

One of the advantages of polyurethane foam-covered prostheses has been that in the first 5 to 10 years after their use, the amount of capsular contraction was found much less than when similar ``slick' prostheses were used. Another advance was their fixation to the surrounding tissue thus giving a more natural appearance and movement with the muscles when the arms were moved in any direction. The formation of a thick capsule also acted as a protection against gel granuloma due to rupture of the prosthesis and has been thought to be a factor in the lower capsule contraction rate. The greatest disadvantage has been that its removal was extremely difficult and this has continued up until the technique described in this paper has been introduced.     

Avoiding complications in arthroscopic subacromial space and instability surgery

Arthroscopic shoulder surgery has become a safe tool for evaluation and treatment of a wide range of shoulder problems with few complications. With ever-improving technology (and commitment to motor skill development among arthroscopists), we can expect to maintain this low rate despite increasing procedure complexity. Avoiding complications in arthroscopic shoulder surgery requires careful preoperative planning, judicious patient selection, a thorough understanding of arthroscopic anatomy, and facility with arthroscopic techniques.
