Intravenous albumin infusion is an effective therapy for hyponatraemia in cirrhotic patients with ascites.

The treatment of moderate to severe hyponatraemia in patients with decompensated liver disease is unsatisfactory. We report our preliminary experience using intravenous infusion of albumin to treat this condition. Three patients with cirrhosis, ascites, and hyponatraemia responded satisfactorily to treatment; one patient with fulminant hepatitis B did not respond. Intravenous albumin infusion is a safe and effective therapy for patients with cirrhosis complicated by hyponatraemia. Its main role may be in preparing patients for surgery, particularly liver transplantation.

Experience with nalbuphine, a new opioid analgesic, in acute myocardial infarction.

A total of 141 patients admitted to hospital with a diagnosis of suspected myocardial infarction were randomized to treatment with intravenous diamorphine (71) or nalbuphine (70). Myocardial infarction was subsequently confirmed in 109 patients. Both drugs provided good analgesia. Heart rate, blood pressure, respiratory rate, peak flow and minute volume were measured over a three-hour study period. Except for a slight fall in systolic blood pressure in the nalbuphine-treated group, there were no statistically significant differences between the groups. The nalbuphine-treated group had higher levels of aspartate aminotransferase and hydroxybutyric acid dehydrogenase but not creatine phosphokinase. The haemodynamic outcome and mortality at three months of the two groups were similar. It is concluded that nalbuphine provides effective analgesia coupled with few adverse circulatory or respiratory effects.

The role of the atria in fluid volume control.

Neural reflexes from the heart, in particular the atria, are well documented and are involved in sodium and water excretion. Current work also indicates that the atria have an important endocrine function. Atrial peptides, which have been recently characterized and synthesized, may play a significant role in the homeostasis of body fluids.

Menstrual disturbances in chronic renal failure.

Twelve female patients undergoing intermittent hemodialysis (HD) and 5 females posttransplantation (PT) were studied. All the HD patients had menstrual disturbances and 5 had galactorrhea. The mean basal LH level was significantly elevated (p less than .05) in patients on HD compared to normal controls, but the mean LH response to luteinizing hormone releasing hormone (LRH) was not significantly different from the control group. Mean basal FSH and the FSH response to LRH was normal. In the PT pateints the LH response to LRH was significantly greater at 120 min when compared to normal females. In the HD group the serum 17B estradiol, progesterone and testosterone levels were significantly lower than in the controls but in the PT group only testosterone levels were significantly lower. These results differ from those previously found in uremic males. Elevated prolactin levels were found in the patients on hemodialysis and correlated well with the presence of galactorrhea. These was no correlation between the elevated prolactin levels and amenorrhea in the patients on hemodialysis but one PT patient with amenorrhea had elevated prolactin levels.

Pulmonary metastases (with admixed epithelial elements) from smooth muscle neoplasms. Report of nine cases, including three males.

This study pertains to an entity characterized by the presence of multiple intrapulmonary nodules, which consist of an admixture of bundles of well-differentiated smooth muscle cells and epithelial-lined spaces. These lesions have been frequently interpreted as a variant of hamartomas. However, in this review of the literature, and careful analysis of nine cases of this entity, we concluded that they should be considered metastases from smooth muscle tumors which incorporate some structures of mature lung parenchyma as they slowly expand. We affirm that the designation "fibroeliomyomatous hamartoma" should be discarded. Our cases occurred in six female and three male patients. In all but one female the primary source for lung metastases was uterus, while the male patients had primary lesions in the saphenous vein, diaphragm, and soft tissues. These lung lesions increase in size and number and are potentially fatal, though this may take many years. Even though the smooth muscle cells of the lung nodules appear bland on light microscopy, we were always able to demonstrate mitotic activity; electron microscopy indicated immaturity of the cells. For these reasons, we believe the tumors to represent metastatic leiomyosarcomas.

Prognostic significance of the white nipple sign in variceal bleeding.

The prognostic significance of the white nipple sign in variceal bleeding was evaluated prospectively in 203 separate admissions for bleeding esophageal varices in 145 cirrhotic patients. During all admissions a standardized protocol of management defined the failure of transfusion and vasoactive drugs (conservative measures) to stop bleeding and the occurrence of early rebleeding, at which time either emergency sclerotherapy or a staple transection of the esophagus was used. The finding of a white nipple in 18 admissions (9%) did not have predictive value as regards the failure of conservative measures to stop bleeding within 24 hours or rebleeding within 5 days, and there was no association with increased mortality. In one case, a white nipple was seen to occur after spontaneous cessation of a variceal venous spurt, suggesting it is a platelet-fibrin plug. The white nipple sign is diagnostic of a varix that has bled but has no adverse prognostic significance.
