Guidelines for clinical use of drugs for involutional osteoporosis

Guidelines for clinical use of drugs for involutional osteoporosis will be released soon in Japan. Seven different types of drugs for osteoporosis are in market for clinical use in Japan. Those includes calcium, estrogens, anabolic steroids, calcitonins, active vitamin D3, ipriflavon, and etidronate. The guidelines recommend to clarify the risk factors in each patient before to start administration of drug. Patients with osteopenia are basically recommended to be followed without any drug treatment, but, patients with osteoporosis are generally recommended to be treated with drug after evaluation of risk factors. After menopause, inhibitors of bone resorption would be recommended as a first choice drug. For monitoring effects of treatment, bone mass measurement is so far the first choice, but bone metabolic markers would be used as well.     

Criteria for selection of patients for emergency portacaval shunt

A computer program analysis of the effect on survival of 74 preoperative factors was performed as part of a prosepctive study of the emergency portacaval shunt in 146 unselected patients with bleeding esophageal varices due to alcoholic cirrhosis. Only ascites, a serum glutamic oxalacetic transaminase level of 100 units or more, and a requirement for 5,000 ml or more of blood transfusion were associated with a statistically significant decrease in survival. However, none of these factors are contraindications to operation because their presence permits a survival rate of 37 to 40%. The only contraindication to emergency portacaval shunt is the combined presence of ascites, jaundice, encephalopathy, and severe muscle wasting, a constellation that was incompatible with survival beyond one year.     

The use of dimethylsulfoxide for fixation of yeasts for electron microscopy

Increasing numbers of young women with ovarian failure and women of advanced reproductive age (> 40 yrs) utilize oocyte donation to treat their infertility. In both groups, women who become pregnant frequently experience multiple gestation, occurring in up to 30% of pregnancies. Advanced maternal age and high-order multiple gestations are associated with an increased risk for obstetric complications. We reviewed the pregnancies of patients with high-order multiple gestations (> or = 3 gestational sacs) with respect to their antepartum course and neonatal outcomes. Mothers were divided into two groups according to age at conception; Group I (> or = 40 yr, n = 20) and Group II (< 40 yr, n = 10). These 30 high-order multiple gestations were found among 127 successful oocyte donation cycles (23.6% of all pregnant patients). Data regarding pregnancy outcomes were gained by chart review and telephone interview. Results demonstrated spontaneous reductions in the number of implantation sites were similar between groups (Group I: 21.4% vs. Group II: 17.6%). Multifetal pregnancy reduction (MFPR) was more often chosen by older women (Group I: 45% vs. Group II: 10%; P < 0.05). Antenatal complications were commonly experienced by both groups (> 80%) as were operative deliveries (> 85%). However, neonatal outcomes were generally good, with only one death occurring in the 79 delivered infants (1.3%). We conclude transferring supernumerary embryos to women undergoing ovum donation places patients at great risk for high-order multiple gestations. These pregnancies are associated with increased antenatal and neonatal complications. Although advanced maternal age is normally an added risk factor, well-screened older patients carrying high-order multiple gestations experienced similar outcomes as younger mothers.
