Learning to Observe Relationships and Coping

Milieu relationships provide the critical background presence to staff's attempts to motivate, regulate, and teach patients how to cope with stress. Forging a connection with hospitalized children and adolescents demands attention to how they respond to adults and engage with staff around milieu expectations. Assessment guides that deal with these issues are presented. Important aspects of children's relatedness are presented in the context of their working models of adults and the influence of these representations on their response to staff. Coping skills are explained with particular emphasis on behavioral coping strategies. Tied to the assessment process are interventions that emphasize staff's role in helping patients manage strong affects and avoid the use of nonproductive behavior regulation strategies.     

Effectiveness of the treatment of chronic non-healing stomach ulcers using copper vapor laser

A group of patients with chronic gastric ulcers received a course of laser treatment with the use of laser on copper vapours. Gastric ulcer was exposed to radiation once in the course of 5 days, the single dose being equal to 10-15 J. Complete healing of the ulcerous defect was attained in 100 out of 110 patients examined. The results of laser therapy were found to be influenced by certain clinical characteristics, namely by age, ulcer size, duration of the last disease exacerbation, and acid-secreting function of the stomach.     

Nephroblastoma with intestinal differentiation

Available are two cases of Wilms's tumor with focal intestinal differentiation. Goblet- and endocrine-like cells as well as those similar to enterocytes were identified in one of the tumors upon electron microscopy. Squamous epithelial, cartilaginous cells, rabdomyoblasts presented in both cases. Problems of histogenesis and prognosis are under discussion.     

Aspects of the morphogenesis of cancer of the endometrium

The paper covers a number of morphogenetic problems of endometrial cancer with reference to multidirectional differentiation of the uterine epithelium affected by tumor. Metaplastic changes of the endometrium observable in three basic variants (tubal, endocervical, squamous cell) can entail dysplasia with resultant malignant transformation. Endometrial cancer shows complex structure of the tumor with sings of multidirectional epithelial differentiation: endometrial, tubal, endocervical, squamous). Morphological features of the tumor and adjacent mucosa, assessed comparatively, suggest a close relationship between the direction of endometrial epithelium differentiation and the new growth histological structure.     

Follistatin and activin A production by the male reproductive tract

Follistatin is a binding protein for the activin and inhibin family of hormones, regulating their biological activity. In the male reproductive tract, the interaction of these factors is likely to be involved in the regulation of the proliferation of several cell types. We have investigated the presence of follistatin and activin A in seminal plasma using specific immunoassays and have localized follistatin and activin/inhibin subunits in the adult human testis, prostate and seminal vesicle to establish their likely sources. High concentrations of immunoreactive follistatin were present in seminal plasma in normal men (mean 97.9 ng/ml; 1.43 ng/ml in peripheral plasma) and were similar in men with oligo/azoospermia and following vasectomy. Follistatin immunoreactivity was localized to both Leydig and Sertoli cells of the testis, and to epithelial cells of the prostate gland and seminal vesicle, which are likely to be the predominant sources of the hormone in seminal plasma. Activin A was also present in seminal plasma in normal men but was undetectable following vasectomy, thus deriving from the testis. Consistent with this finding, the betaA-subunit was immunolocalized in Sertoli and Leydig cells but was not present in seminal vesicle or prostate gland. The functional significance of the high concentrations of follistatin secreted into seminal plasma by the prostate gland and/or seminal vesicle is uncertain, but they may regulate the biological activity of testis-derived activin A and inhibin B.
