Perinatal growth hormone (GH) physiology : effect of GH-releasing factor on maternal and fetal secretion of pituitary and placental GH.

To study regulation of the secretion of human pituitary GH (hGH) and placental GH (hPGH) in the pregnant woman and human fetus, the GH-releasing factor Sermorelin [GRF-(l–29)-NH2] was administered to pregnant women at term (n = 5), just before elective cesarean section; saline was administered in control studies (n = 5). The effects of GRF-(1–29)-NH2 administration on maternal and fetal serum concentrations of hGH and GRF-(l–29)-NH2 and maternal serum levels of hPGH were evaluated at birth. The mean time span between injection and birth was 20 min (range, 15–25 min). Cord serum hGH concentrations were similar in infants of GRF-(1–29)-NH2-injected mothers and control infants. GRF-(l–29)-NH2 elicited a consistent but small rise in maternal hGH serum concentrations (P = 0.08), whereas hPGH concentrations remained unaltered. Finally, GRF-(l–29)-NH2 concentrations were undetectable in cord serum, but readily detectable in concomitantly obtained maternal serum. In conclusion, these data suggest that hGH secretion in the pregnant woman at term is suppressed at the pituitary level, that GRF does not affect hPGH secretion, and that fetal hGH secretion is independent of circulating maternal GRF, probably because of lack of transplacental GRF passage.

Perineal herpes simplex infection in bedridden geriatric patients.

BACKGROUND: Herpes simplex virus (HSV) lesions are prone to reactivation and recurrence in response to various local or systemic triggering factors. OBJECTIVE: To study the characteristics of five bedridden geriatric patients who presented with herpetic recurrences on the buttocks, gluteal cleft, and perianal region during hospitalization. METHODS: Data were gathered regarding age, gender, reason for hospitalization, localization of lesions, clinical presentation, previous clinical diagnosis and topical treatments, immune status and immunosuppressant drug intake, as well as prior history of labial or genital herpes. A skin biopsy was taken for histologic examination and immunohistochemical viral identification. Viral culture and viral serology were performed and data regarding antiviral therapy were recorded. RESULTS: The five patients (three women, two men) were aged >80 years and hospitalized for either severe drug-induced renal insufficiency (one case), severe pneumonia (two cases), or stroke causing restricted mobility (two cases). Numerous well demarcated, painful ulcerations developed in the perianal region of these patients, and one patient also presented with some vesicular lesions. The lesions had been confused with mycotic and/or bacterial infections for 10-14 days. No inguinal lymphadenopathies were present and there was no fever. None of the patients had a previous history of recurrent labial or genital HSV infections or HIV infection. Histology was suggestive of HSV infection in two of five patients. Immunohistochemistry identified HSV type I (three patients) and HSV type II (two patients) infections. Viral culture with immunofluorescence viral identification revealed HSV type I in one of the four patients in whom a swab for viral culture was taken. Serology revealed past HSV infection. All lesions cured gradually after 10-14 days of intravenous acyclovir (aciclovir) treatment. CONCLUSION: Herpetic lesions of the perineal region represent a rare complication in bedridden geriatric patients in the absence of a previous history of HSV infections at the same site. Common traits of patients with this condition were the presence of numerous ulcerated lesions, prolonged time course, and confinement to bed. The latter probably modifies the skin condition, which triggers viral reactivation and favors cutaneous extension of the infection. Complementary diagnostic methods for viral detection and identification are mandatory. [less ▲]

A period and a prediction for the Of ? p spectrum alternator HD 191612

The observational picture of the enigmatic O-type spectrum variable HD 191612 has been sharpened substantially. A symmetrical, low-amplitude light curve with a period near 540 days has recently been reported from Hipparcos photometry. This period satisfies all of the spectroscopy since at least 1982, including extensive new observations during 2003 and 2004, and it has predicted the next transition during 2004 September - October. Measurements of the Ha equivalent width reveal a sharp emission peak in the phase diagram, in contrast to the apparently sinusoidal light curve. The He II absorption-line strength is essentially constant, while He I varies strongly, possibly filled in by emission in the O6 state, thus producing the apparent spectral type variations. The O8 state appears to be the "normal" one. Two intermediate O7 observations have been obtained, which fall at the expected phases, but these are the only modern observations of the transitions so far. The period is too long for rotation or pulsation; although there is no direct evidence as yet for a companion, a model in which tidally induced oscillations drive an enhanced wind near periastron of an eccentric orbit appears promising. Further observations during the now predictable transitions may provide a critical test. Ultraviolet and X-ray observations during both states will likely also prove illuminating. [less ▲]

Period of the Si-star in NGC 2169

in Astronomy and Astrophysics (1994), 285

For the Si Ap-star known in NGC 2169 (Gr.9 in the cluster), a period between 0.60 and 0.62 d, most likely about 0.606 d, agrees with all known observations, and is much more probable than the period 1.56 ... [more ▼]

For the Si Ap-star known in NGC 2169 (Gr.9 in the cluster), a period between 0.60 and 0.62 d, most likely about 0.606 d, agrees with all known observations, and is much more probable than the period 1.56 d proposed by Maitzen & Lebzelter (1993). The obtained period is among the shortest ones known for Ap stars. [less ▲]
