Nutritional condition and absorptive capacity of 14 infants with short bowel syndrome

We examined the absorptive capacity and the nutritional condition of 14 infants with short bowel syndrome, whose residual small intestine was 90 cm or less. Their age ranged from 1 year to 18 years. Examined items were body weight, height, serum albumin, total cholesterol, triglyceride, fat soluble vitamins, trace elements and rapid turn over protein as markers of the nutritional condition. Fecal fat, fecal bile acid, d-xylose absorption test, sugar-, amino acid-evoked potential difference in the small intestine and disaccharidase activity of the mucosa were examined as markers of the absorptive capacity. Our results showed that the body weight was below the normal range in the patients with small intestine of less than 50 cm. Most nutritional markers were within normal range, however, cholesterol and vitamin D were low in the patients with fat malabsorption, especially in patients with less than 50 cm of small intestine. Fecal bile acid was higher than the normal range in all the patients. Potential difference was in normal range or slightly lower than normal in all the patients. We concluded that infants with less than 50 cm of small intestine had malabsorption of sugar, protein and fat. Therefore, prolonged nutrient support, especially fat, is necessary.     

Disappearance of Philadelphia chromosomes after remission induction in lymphoid crisis of chronic myelogenous leukemia]

The authors report a rare case of chronic myelogenous leukemia (CML) in which the Ph1 clone disappeared after remission induction of lymphoid crisis. A 58-year-old man was admitted to our hospital because of fever in July 1988. The white cell count was elevated. Bone marrow aspirate showed hypercellularity with myeloid hyperplasia. In the chromosomal analysis, Ph1 chromosomes were detected in 100% of bone marrow cells analysed. Diagnosis of CML was made and treatment was initiated with recombinant interferon-alpha 2a. Hematological remission without cytogenetic improvement was achieved. In March 1990 he developed lymphoid crisis with proliferation of CD10-positive cells. The chromosomal analysis revealed additional abnormalities including, 45, X, -Y, t(9;22) (q34;q11), +1, -8. With vincristine 0.6 mgX4, pirarubicin 15 mgX4, dexamethasone 40 mgX4 therapy complete remission was obtained. In December 1990 the Ph1 positive clone completely disappeared judging from normal karyotypes in the chromosomal analysis and the disappearance of M-bcr gene rearrangement.     

Intracranial arterial vasospasm associated with pituitary apoplexy after head trauma--case report.

A case of intracranial arterial vasospasm caused by pituitary apoplexy after head trauma is reported. In this case, pituitary apoplexy was secondary to head trauma, and the vasospasm was thought to be due to subarachnoid hemorrhage from a pituitary tumor. No such case has previously been reported in the literature.     

Uptake of 99Tcm-MDP in lung metastasis from osteosarcoma: clinical and animal studies

Bone scintigraphy was performed in 17 patients with previously known lung metastases of osteosarcoma. 99Tcm-MDP uptake was observed in all primary bone lesions but lung metastatic lesions were positive in only six patients (35%). 99Tcm-MDP uptake by lung metastases was significantly correlated with bone and osteoid formation in the metastatic lesions and preoperative serum ALPase values. These clinical observations were confirmed by using nude mice transplanted with human lung metastatic osteosarcoma. 99Tcm-MDP scintigraphy appears to be useful for detecting lung metastases of osteosarcoma only in a selected group of patients.     

A case of prostatic leiomyosarcoma

A case of a 19-year-old male with leiomyosarcoma of the prostate is reported. He visited our hospital with the chief complaint of urinary retention in December, 1983. Following overall examination, needle biopsy of the prostate gland was performed with the suspicion of sarcoma. Histology of the prostate revealed leiomyosarcoma. Two courses of combined chemotherapy were given, but the tumor continued to enlarge. The patient died in April, 1984, 5 months after the appearance of the first symptom.     

‘Ischemic tolerance’ phenomenon detected in various brain regions

We investigated the effects of mild and non-lethal ischemic insult on neuronal death following subsequent lethal ischemic stress in various brain regions, using a gerbil model of bilateral cerebral ischemia. Single 10-min ischemia consistently caused neuronal damage in the hippocampal CA1, CA2, CA3 and CA4, layer III/IV of the cerebral cortex, dorsolateral part of the caudoputamen and ventrolateral part of the thalamus. On the other hand, in double ischemia groups, 2-min ischemic insult 2 days before 10-min ischemia exhibited significant protection in the CA1 and CA3 of the hippocampus, the cerebral cortex, the caudoputamen and the thalamus. Five-min ischemic insult 2 days before 10-min ischemia also showed protective effect in the same areas as those of 2-min ischemia except for the CA1 region of the hippocampus, while 1-min ischemic insult exhibited no protective effect in any brain regions. In the immunoblot analysis, both 2- and 5-min ischemia caused increased synthesis of heat shock protein 72 (HSP 72) in the hippocampus, but 1-min ischemia did not. The present study demonstrated that the ‘ischemic tolerance’ phenomenon was widely found in the brain and also suggested that ischemic treatment severe enough to cause HSP 72 synthesis might be needed for induction of ‘ischemic tolerance’.     

Superovulation-induced transient hyperprolactinemia in human in vitro fertilization and embryo transfer

To examine the effects of transient hyperprolactinemia on in vitro fertilization and embryo transfer, 61 cycles in 50 euprolactinemic ovulatory women with irreparable tubal diseases were stimulated with clomiphene (CC) alone or CC and human menopausal gonadotropin followed by human chorionic gonadotropin (hCG). Serum prolactin (PRL) increased after hCG administration with peak values of 45.4 +/- 4.2 ng/ml on the day of laparoscopic oocyte aspiration. The highest serum estradiol (E2) concentration was found on the day before PRL peak and serum progesterone (P) began to increase after hCG injection concomitant with the PRL rise. The group having 50 ng/ml or more of PRL (34 cycles) had significantly higher levels of E2 during preovulatory and early luteal phase compared to those of the group having less than 50 ng/ml of PRL (27 cycles) but there was no significant difference between the P levels in the two groups. In the higher PRL group 72 (62.1%) of 116 collected oocytes were fertilized and 6 (20.0%) conceived. In the lower PRL group 45 oocytes (58.4%) of 77 were fertilized and 3 (12.5%) became pregnant. These data suggest that elevated serum PRL concentrations may have no effect on fertilization of oocytes in vitro or embryonic development.
