Abstract: Lymphocytes from 18 patients with the Wiskott-Aldrich Syndrome (WAS) were examined by scanning electron microscopy (SEM). Most peripheral blood lymphocytes from normal individuals are covered with slender microvillus projections, but a large proportion of lymphocytes from WAS patients were found to be relatively devoid of microvilli. A lymphocyte morphology scoring system was developed to quantify the density of microvilli: Grade 4 classified those lymphocytes with greater than 75% of the surface covered with microvilli with progressive decrements to grade 1, which were those without microvilli. The mean lymphocyte morphology score of eight normal individuals was 3.62 +/- .22. The mean lymphocyte score of WAS patients was substantially lower (2.89 +/- .27, P less than .001). In addition, WAS lymphocytes often were qualitatively abnormal, with short, blunted microvilli. These morphological criteria were used to diagnose WAS from the cord blood lymphocytes of one "at-risk" patient. Thus, WAS is the first primary immunodeficiency in which morphological abnormalities have been identified that can aid in diagnosis.

Abstract: Cerebral cysticercosis is a parasitic infestation with a highly variable prognosis and diverse clinical manifestations. Over the period of two years 51 patients were studied prospectively with this infestation, paying particular attention to the duration and severity of the illness, clinical course, CT findings and therapeutic modalities. Patients with parenchymal cysts or calcification without hydrocephalus had a benign disorder presenting commonly with seizures. This type of infestation usually is long-standing, almost never requires surgical treatment, responds to praziquantel therapy and has a good prognosis. In contrast, patients who present with hydrocephalus, large supratentorial cysts, multiple granulomata with cerebral oedema or with vasculitis and cerebral infarction, have an aggressive, acute or subacute illness, presenting with raised intracranial pressure, gait disturbances, mental changes, seizures, cranial nerve palsies, hemisphere syndromes, chronic meningitis and stroke. This malignant form usually requires surgical therapy, does not respond to praziquantel and may produce a fatal outcome or serious sequelae.

Abstract: We studied the interaction between dopamine and estradiol on PRL release by cultured normal and tumorous PRL-secreting cells prepared from human pituitaries. If pituitary glands were obtained within 3 h after sudden death of previously normal individuals, the viability of isolated pituitary cells prepared by dispersion with dispase was more than 75%. After 4 days of culture, dopamine (500 nM) inhibited PRL release by cells prepared from four normal pituitaries by 24 +/- 3% (+/- SEM). Pretreatment of the cells with 100 nM estradiol did not alter dopamine-mediated inhibition of PRL release. Estradiol alone increased basal PRL release and cell PRL content. Cultured PRL-secreting pituitary tumor cells, obtained by transsphenoidal operation from four patients, were similarly sensitive to dopamine. Estradiol stimulated tumor cell PRL release and content, but significantly diminished the inhibitory effect of dopamine. The estrogen receptor blocker tamoxifen did not alter PRL release, but it did reverse the estradiol-induced insensitivity of the prolactinoma cells to the dopamine agonist bromocriptine. In conclusion, these in vitro results indicate that estrogens do not antagonize the effect of dopamine on normal human PRL-secreting pituitary cells. In human pituitary tumor cells, however, estradiol decreased the sensitivity of PRL release to dopamine (agonists), and the estrogen action can be acutely reversed by tamoxifen.
