Abstract
Burns to the hand can cause anatomical and functional limitations due to burn sequelae and treatment obstacles that arise during the rehabilitation process. A questionnaire consisting of four open-ended questions was distributed at the 1993 American Burn Association Breakfast Session, "Rehabilitation of the Burned Hand." The questionnaire was designed to gather information regarding common postburn deformities and treatment obstacles that occur in the acute and postacute phase of burn rehabilitation. Information was collected from 38 respondents and frequency distributions were compiled. The deformities and treatment obstacles are discussed in relation to the current literature and clinical management of hand burns.

Abstract
PURPOSE Children under 5 years old with medulloblastoma (MB) have a poor prognosis. They are more susceptible to the deleterious effects of craniospinal irradiation (CSART) and have a higher relapse rate when treated with low-dose CSART alone. We, thus, embarked on a prospective trial testing the usefulness of very low dose CSART and adjuvant chemotherapy. This is an update of a previous report on these patients. METHODS AND MATERIALS Between January 1988 and March 1990, 10 patients with medulloblastoma were treated using 18 Gy radiation therapy (RT) to the craniospinal axis, a posterior fossa (PF) boost to 50.4-55.8 Gy and chemotherapy consisting of vincristine (VCR) weekly during RT. This was followed by VCR, cis-diamminedichloroplatinum (CDDP), and lomustine (CCNU) for eight, 6-week cycles. Patients between 18 and 60 months of age without evidence of tumor dissemination were eligible for study. Follow-up was available until September 1994 with a median follow-up for living patients of 6.3 years from diagnosis. RESULTS Actuarial survival at over 6 years is 70 +/- 20%. Three of the 10 patients relapsed and died. In one patient, the relapse developed in the spine and brain outside the posterior fossa, in the second, concurrently in the posterior fossa, brain and spine, and the third, only in the spine. One surviving child developed a brain stem infarct 4.8 years after diagnosis and has since almost fully recovered. A mean intelligence quotient (IQ) score of 103 in six patients surviving at least 1 year is unchanged from the baseline group score of 107. Five children tested at baseline and 2 years following treatment had IQ scores of 101 and 102, respectively. Six children tested at baseline and at 3 years had IQ scores of 106 and 96, respectively. Excluding the child tested shortly after his brain stem infarct, baseline and 3 year IQ scores were 103 and 97, respectively. Five of the seven long-term survivors grew at rates significantly below their expected velocities during the follow-up period, while the others grew normally. Three patients have received growth hormone, and none have required thyroid replacement. CONCLUSIONS These data suggest that medulloblastoma patients can be cured with chemotherapy and reduced doses of craniospinal irradiation. The low doses of CSART given by us in conjunction with cis-platin-based chemotherapy produce minimal neurocognitive damage. Growth velocities in very young children so treated are, however, dramatically reduced. Better means of improving the therapeutic ratio are still needed.

Abstract
In this retrospective review we assessed the frequency with which atypical glandular cells in cervical smears predict cervical glandular lesions. Asymptomatic patients (n=34) with one or more smears showing atypical glandular cells aand subsequent histopathological assessment were studied. Independent cytological and histological review was undertaken. Cytological review confirmed atypical glandular cells in 29 cases, 17 of which had coexisting squamous dyskaryosis. Histological review of these 29 cases revealed glandular neoplasia in 13 (45%) and microglandular hyperplasia (MEH) in an additional four (14%). Initial reporting had underestimated the prevalence of glandular neoplasia.

Abstract
This article examines treatment outcomes of alcohol and drug abusing patients admitted to a university-based alcohol and drug outpatient clinic. Treatment effectiveness of two treatment models were evaluated. The psycho-educational approach utilized a teacher-student model with the goal of imparting information about drugs and consequences of use. The recovery-oriented approach utilized a patient-counselor collaborative model where patients were encouraged to be active in progressing through sequential stages of pre-recovery tasks. Patients in the psycho-education group stayed in treatment longer and were more likely to rate treatment as useful. Results showed minimal differences between the two groups in terms of Addiction Severity Index scores, Drug Attitude, and urine drug screen results.

Abstract
To better understand the assembly mechanism for the progesterone receptor (PR), we have developed cell-free systems for studying interactions of PR, hsp90, and other associated proteins. When PR is incubated in rabbit reticulocyte lysate, its association with hsp90, hsp70, the three immunophilins FKBP54, FKBP52 and CyP-40, and with p23 is observed. These interactions require ATP/Mg2+ and when ATP is limiting the PR complex is altered to one containing the proteins p60 and p48, but lacking immunophilins and p23. We have studied two pre-formed hsp90 complexes that may participate in the assembly of PR complexes. One contains hsp90 bound to hsp70 and p60 and this complex forms spontaneously in the absence of ATP. A second complex contains hsp90 bound to p23 plus the three immunophilins and some hsp70. The formation of this complex requires ATP. In further studies we have shown that purified hsp90 can bind to purified p23 and this interaction requires both ATP and molybdate. This explains, in part, the known effects of ATP and molybdate on assembly of PR complexes.

Abstract
This study investigated lifetime prevalence rates, demographic characteristics, childhood conduct disorder and adult antisocial features, suicide attempts, and cognitive impairment in individuals with obsessive-compulsive disorder (OCD) uncomplicated by or comorbid with any other psychiatric disorder. The data are from the NIMH Epidemiologic Catchment Area (ECA) study, and the current analyses compared subjects with uncomplicated OCD (no history of any other lifetime psychiatric disorder), comorbid OCD (with any other lifetime disorder), other lifetime psychiatric disorders, and no lifetime psychiatric disorders across these variables. OCD in its uncomplicated and comorbid form had significantly higher rates of childhood conduct symptoms, adult antisocial personality disorder problems, and of suicide attempts than did no or other disorders. Comorbid OCD subjects had higher rates of mild cognitive impairment on the Mini-Mental Status Exam than did subjects with other disorders. These findings suggest that a subgroup of OCD patients may have impulsive features, including childhood conduct disorder symptoms and an increased rate of suicide attempts; wider clinical attention to these outcomes is needed.

Abstract
The purpose of this pilot was to improve the peer review process by enhancing the communication skills of staff nurses. Communication skill building was taught to staff members with practice time allotted. The paradigm shift occurred in teaching staff that communication is a learned skill built through practice and not solely a cognitive skill. The results of this pilot demonstrated improved verbal communication, increased comfort with peer review, improved ability to separate performance from individual style differences, and increased accuracy with which staff rate themselves on self evaluations. An indirect benefit has been improved teamwork from increased support among the staff.

Abstract
This exploratory study describes the heterogeneity of the neuropsychological deficits that characterize familial schizophrenia. Forty-six familial schizophrenics showed significantly more variability in abstraction and problem-solving and motor control than 39 non-familial schizophrenics. Cluster analyses of these two neuropsychological parameters indicate that while the non-familial schizophrenics fall into one homogeneous cluster, the familial schizophrenics fall into three relatively distinct clusters which differ significantly in their morbid risk for schizophrenic-spectrum disorder. These preliminary data suggest that frontal lobe deficits are associated with an increased familial risk for schizophrenia.

Abstract
Several different oncogenes and growth factors promote G1 phase progression. Cyclin D1, the regulatory subunit of several cyclin-dependent kinases, is required for, and capable of shortening, the G1 phase of the cell cycle. The present study demonstrates that transforming mutants of p21ras (Ras Val-12, Ras Leu-61) induce the cyclin D1 promoter in human trophoblasts (JEG-3), mink lung epithelial (Mv1.Lu), and in Chinese hamster ovary fibroblast cell lines. Site-directed mutagenesis of AP-1-like sequences at -954 abolished p21ras-dependent activation of cyclin D1 expression. The AP-1-like sequences were also required for activation of the cyclin D1 promoter by c-Jun. In electrophoretic mobility shift assays using nuclear extracts from cultured cells and primary tissues, several AP-1 proteins (c-Jun, JunB, JunD, and c-Fos) bound the cyclin D1 -954 region. Cyclin D1 promoter activity was stimulated by overexpression of mitogen-activated protein kinase (p41MAPK) or c-Ets-2 through the proximal 22 base pairs. Expression of plasmids encoding either dominant negative MAPK (p41MAPKi) or dominant negatives of ETS activation (Ets-LacZ), antagonized MAPK-dependent induction of cyclin D1 promoter activity. Epidermal growth factor induction of cyclin D1 transcription, through the proximal promoter region, was antagonized by either p41MAPKi or Ets-LacZ, suggesting that ETS functions downstream of epidermal growth factor and MAPK in the context of the cyclin D1 promoter. The activation of cyclin D1 transcription by p21ras provides evidence for cross-talk between the p21ras and cell cycle regulatory pathways.

Abstract
OBJECTIVE To determine if subclinical hepatotoxicity is associated with exposure to perchloroethylene at concentrations commonly experienced in the workplace, and whether surveillance with serum hepatic transaminase activity underestimates such effects. METHODS Hepatic parenchymal echogenicity on ultrasonography and serum hepatic transaminase activity were compared in 29 community based dry cleaning operators exposed to perchloroethylene, and a control group of 29 non-exposed laundry workers. Perchloroethylene exposure was assessed by work history and air monitoring. RESULTS Mean hepatic transaminase activities were minimally increased in dry cleaners compared with laundry workers. Increased alanine aminotransferase activities, between 1.0 and 1.5 times the normal limits, were found in five of 27 (19%) dry cleaners compared with one of 26 (4%) laundry workers. In contrast, diffuse parenchymal changes in echogenicity, as determined by hepatic ultrasonography, were increased nearly twofold in dry cleaners, occurring in 18 of 27 (67%) dry cleaners compared with 10 of 26 (39%) laundry workers (P < 0.05), and were most strongly associated with increased perchloroethylene exposure in older dry to dry or wet transfer operations (odds ratio 4.2, 95% confidence interval 1.1-15.3). Mean eight hour time weighted average perchloroethylene exposure for dry cleaners was 16 ppm, which is less than the permissible exposure limit of 100 ppm in the United States. CONCLUSIONS It was concluded that mild to moderate hepatic parenchymal changes occur more frequently in workers exposed to perchloroethylene than in populations not exposed to chemical solvents, and that these effects are underestimated by serum hepatic transaminase activity.
