The Marfan syndrome with an XYY chromosome pattern.

A 36-year-old man who was diagnosed to have the Marfan syndrome with an XYY chromosome pattern is reported. He was tall with long limbs and arachnodactylia, and had severe aortic regurgitation (AR). The chromosome pattern studied in specimens of blood and bone marrow revealed an XYY chromosome pattern. The relationship between the Marfan syndrome and an XYY chromosome pattern is discussed.

[Neonatal hyperbilirubinemia of inadequately breast-fed infants and the effect of formula supplementation].

One hundred and fifty full-term breast-fed infants were analysed for their oral intake in the first 6 days. Fifty infants with less than 330 ml/kg/6 days breast feeding were defined as inadequately breast-fed infants. Twenty inadequately breast-fed infants without formula supplementation had significantly lower total fluid intake, lower total calorie intake, more body weight loss and significantly higher rates of hyperbilirubinemia and requirement of phototherapy when compared with the control group of 100 infants with more than 330 ml/kg/6 days breast feeding. On the other hand, 30 inadequately breast-fed infants with formula supplementation had significantly higher total fluid intake, higher total calorie intake, lower body weight loss and requirement of phototherapy than those without formula supplementation. From these data, we suggest that (1) Inadequate feeding may be a factor responsible for the higher prevalence of early neonatal jaundice in breast-fed infants reported in the literature. (2) Lower fluid intake, lower calorie intake and greater body weight loss may be associated with the higher incidence of hyperbilirubinemia and requirement of phototherapy. (3) Formula supplementation may be helpful in decreasing the risk of hyperbilirubinemia in inadequately breast-fed infants.

Action spectrum for UV erythema and reproduction of the skin lesions in hydroa vacciniforme.

Action spectra for UV erythema and reproduction of the skin lesions in 4 patients with hydroa vacciniforme (HV) were studied. Vesicles were successfully reproduced by repeated daily monochromatic irradiations of 330, 340, 350 and 360 nm for 5, 6 or 7 days. The daily doses were equivalent to global solar radiation for 70-190 min. The vesicles produced were identical to those of HV, macroscopically and histologically. Repeated daily exposures to a small dose of UVA produced vesicles, whereas a large but single exposure to UVA failed to do so. Daily exposures to UVB failed to produce the vesicles. The minimal erythema dose (MED) was lower than the minimum limits of the normal persons in the 290-310 nm range.

A case of liver cirrhosis with large portacaval shunt from the superior mesenteric vein: normalization of reversed portal blood flow with medical treatment.

A case of liver cirrhosis with large portacaval shunt from the superior mesenteric vein is reported. The portal blood flow was diagnosed as reversed on admission, but normalized with treatment. Blood flow was measured noninvasively and repeatedly using an ultrasonic Doppler duplex system. The reversed portal flow led to the superior mesenteric vein, right (and some left) internal inguinal vein, and inferior vena cava. This rare collateral pathway was clearly demonstrated by percutaneous transhepatic portalgraphy. A link between shunt and an appendectomy carried out 22 yr ago is considered, and the possibility of the temporarily reversed portal blood flow on admission being due to deteriorated hepatic hemodynamic conditions is discussed.
