Primary papillary serous cystadenocarcinoma of broad ligament

A rare case of an advanced primary broad ligament carcinoma is discussed, with a review of the literature regarding its incidence, presentation and management. This patient showed a complete response to adjuvant cisplatin-based chemotherapy following panhysterectomy and is presently without any evidence of disease, 15 months after completion of her treatment.     

脐血LAK细胞生物学特性影响因素的研究

采集２３名产妇的脐带血和８名正常成人的外周血制备ＬＡＫ细胞，随机分为４组，在培养第３，５，７，１４天，分别利用ＭＴＴ法和＾１２５Ｉ－ＵｄＲ释放法对４组ＬＡＫ细胞的增殖力和杀伤活性进行了测定，同时用细胞毒方法测定培养７天的ＬＡＫ细胞的免疫表型。结果发现，在不同培养时间，脐血来源的ＬＡＫ细胞增殖力显著高于成人血ＬＡＫ细胞（Ｐ〈０．０５或Ｐ〈０．０１），成人血清组，脐血血清组，红细胞组ＬＡＫ细胞增殖力有     

The clinical phenotypes of juvenile bipolar disorder: toward a validation of the episodic-chronic-distinction.

BACKGROUND: Recent research has addressed the issue of subtyping juvenile bipolar disorder (JBD). Accordingly, we set out to find out, in a naturalistic sample of bipolar children and adolescents with mania and mixed mania, whether the most useful subtyping should be based on clinical features (elated vs. irritable) or course (episodic vs. chronic). METHODS: We studied 136 patients, 81 male patients (59.6%) and 55 female patients (40.4%), mean age 13.5 +/- 2.9 years, meeting the DSM-IV diagnosis of bipolar disorder, assessed by a structured clinical interview (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version [K-SADS-PL]). RESULTS: Regarding course, 77 patients (56.6%) had an episodic course and 59 patients (43.4%) had a chronic course. Patients with chronic course were significantly younger, had an earlier onset of JBD, and presented a more frequent comorbidity with disruptive behavior disorders. According to the prevalent mood disturbance, 75 patients (55.1%) showed an elated and 61 patients (44.9%) showed an irritable mood. Elated mood was more frequent in patients with episodic course, whereas irritable mood was more frequent in the patients with chronic course. CONCLUSIONS: These findings suggest that chronic versus episodic course may be a putative differential feature. Further validation of such a distinction would require prospective studies, temperament evaluation, gender and neurobiologic approaches, and differential psychopharmacologic assignment and response.     

Lethal Congenital Muscular Dystrophy with Arthrogryposis Multiplex Congenita: Three New Cases and Review of the Literature

Congenital muscular dystrophy (CMD) comprises a heterogeneous group of muscle disorders. We report on two stillborn sibs with early lethal CMD and a prematurely born boy who died within minutes after birth. The pregnancies were complicated by polyhydramnios. All presented with arthrogryposis multiplex congenita, severe muscle wasting, lung hypoplasia, and hydrops. The muscle biopsies showed fibrosis, variation in fiber size, and extensive fat replacement compatible with muscular dystrophy. Fatal CMD seems to be distinct from CMD with survival after birth and is probably autosomal recessively inherited.

High-risk AML evidenced by a monoclonal antibody

A monoclonal antibody has been raised against a surface membrane antigen present on leukemic myeloblasts. In 52 consecutive patients with acute myeloid leukemia treated in a standardized fashion with intensive chemotherapy the immunologic subclass with respect to this antigen was correlated to the clinical outcome. We found the expression of this antigen to predict a poor prognosis, when measured as survival of CR-patients and as survival after 1st relapse.     

The ordered transmission disequilibrium test: detection of modifier genes

We consider the problem of detection of modifier genes that lead to variations in a disease‐related continuous variable (DRCV), such as the age of onset or a measure of disease severity, in a strategy of candidate genes. We propose a novel method, the ordered transmission disequilibrium test (OTDT), to test for a relation between the clinical heterogeneity expressed by a DRCV and marker genotypes of a candidate gene. The OTDT applies to trio families with one patients and his parents, all three genotyped at a bi‐allelic marker M. The OTDT aims to find a critical value of the DRCV which separates the sample of families in two subsamples in which the transmission rates are significantly different. We investigate the power of the method by simulations under various genetic models and covariate distributions and compare it with a linear regression analysis. Genet.

Rh phenotype prediction by DNA typing and its application to practice

The complexity of the RHD and RHCE genes, which is the greatest of all blood group systems, confounds analysis at the molecular level. RH DNA typing was introduced in 1993 and has been applied to prenatal testing. PCR-SSP analysis covering multiple polymorphisms was recently introduced for the screening and initial characterization of partial D. Our objective is to summarize the accrued knowledge relevant to the approaches to Rh phenotype prediction by DNA typing, their possible applications beyond research laboratories and their limitations. The procedures, results and problems encountered are highly detailed. It is recommended that DNA typing comprises an analysis of more than one polymorphism. We discuss future directions and propose a piecemeal approach to improve reliability and cost-efficiency of blood group genotyping that may eventually replace the prevalent serology-based techniques even for many routine tasks. Transfusion medicine is in the unique position of being able to utilize the most extensive phenotype databases available to check and develop genotyping strategies.
