Disseminated hereditary gastrointestinal polyposis with orocutaneous hamartomatosis (Cowden's disease).

Cowden's disease, first described by Lloyd and Dennis in 1962, is a rare disseminated polyposis of the gastrointestinal tract with an autosomal dominant inheritance pattern, infrequently cited in the contemporary gastroenterological literature. In addition to multiple polyps, which are scattered throughout the gastrointestinal tract from the mouth to the anus, orocutaneous hamartomas and frequent benign and malignant cutaneous, thyroid and breast tumors are thought to represent the most common manifestations of the disease. Ectodermal lesions are most frequently reported as a salient feature, and represent the most consistent element in the definition of this condition in the majority of cases, most of which are recorded in the dermatological literature (multiple hamartoma syndrome or Cowden's disease). This article presents four cases of Cowden's disease, the patients being members of two genetically unrelated families. All four patients had disseminated polyposis of the gastrointestinal tract, extending from the oral mucosa to the anus, while the cutaneous lesions and the concomitant tumors were present either in a fully developed or only rudimentary form, or were even absent. The authors propose that the term "disseminated hereditary gastrointestinal polyposis with orocutaneous hamartomatosis " be introduced and consistently used in the gastroenterological literature when referring to Cowden's disease, which seems more common than previous reports in the literature would indicate.

Keratodermia palmoplantaris of the Unna-Thost type in Slovenia.

Keratodermia palmoplantaris of the Unna - Thost type was studied in the population of Slovenia. Altogether 157 patients were recorded: 106 were examined by the authors; for the other 51, anamnestic data were used. Special attention was paid to the accompanying symptoms which are more or less rarely mentioned in the literature: hyperkeratosis of the elbows and knees, transgredience of the hyperkeratosis, hyperkeratotic changes of the nails and changes of the teeth. It is estimated that there are in Slovenia 8.44 PPK UT patients per 100 000 inhabitants.

Antepartum, transabdominal near infrared spectroscopy: feasibility of measuring photon migration through the fetal head in utero.

OBJECTIVE: We report the feasibility of measuring photon migration through the fetal head in utero using antepartum, transabdominal, near infrared (NIR) spectroscopy. METHODS: We developed a continuous wave (CW) spectrometer that incorporates a halogen light source, silicon photodetectors, and a differential processing circuit for antepartum, transabdominal, NIR spectroscopy. By placement of the light source and photodetector on the midline of the maternal abdomen above the fetal head at a separation (approximately 10 cm) large enough for the light to propagate through maternal and fetal tissues via multiple scattering events before being detected at the surface and the use of filtered illumination and detection at wavelengths (760 nm, 850 nm), which coincide with the absorption bands of oxygenated and deoxygenated hemoglobin in the NIR window, we performed studies to evaluate whether antepartum, transabdominal NIR spectroscopy can measure photon migration through the fetal head in utero. RESULTS: The results demonstrate that the CW spectrometer we developed can be employed to make NIR measurements from the maternal abdomen at a 10 cm source-detector separation, with an excellent signal-to-noise ratio. Furthermore, a variety of antepartum, transabdominal NIR measurements that we performed on patients undergoing a routine nonstress test demonstrate the feasibility of measuring photon migration through the fetal head in utero. CONCLUSIONS: Preliminary assessment of transabdominal NIR spectroscopy suggests that this technique can enable photon migration through the fetal head in utero. This is an important step towards the development of this technique for measuring and quantifying fetal cerebral blood oxygenation in utero.

A role for scavenger receptors in phagocytosis of protein-coated particles in rainbow trout head kidney macrophages.

In macrophages of higher vertebrates, Fc receptors and receptors for complement and other serum factors, are generally known to enhance the phagocytic process. In lower vertebrates like salmonid fishes, none of these or other phagocytic receptors have been thoroughly characterized. The purpose of this study was to elucidate to what extent these and other receptors are involved in the process of phagocytosis in rainbow trout (Oncorhynchus mykiss) head kidney macrophages. We used tosyl activated, paramagnetic dynabeads (2.8 microm in diameter), specifically coated with 125I labeled Atlantic salmon (Salmo salar) IgM or bovine serum albumin (BSA) as phagocytic probes. The effect of complement opsonization was also investigated by incubating the beads in serum. Our results indicate that neither the Fc- nor the complement-receptor(s) were important for phagocytosis of these beads. Our data support the idea that scavenger receptors are involved in phagocytosis in rainbow trout head kidney macrophages, as the use of a competitive scavenger receptor ligand extensively decreased degradation of the labeled protein coat on the beads.
