Clinical results of intraperitoneal hyperthermic perfusion combined with surgery in patients with peritoneal recurrence from gastric cancer

Six patients with peritoneal recurrence after radical operation for gastric cancer were treated by an intraperitoneal hyperthermic perfusion (IPHP) combined with surgery (IPHP group). Immediately after surgery, a 2-hour IPHP was performed, using a perfusate containing 10 micrograms/ml of MMC, warmed at the inflow temperature of 46.5 +/- 1.1 degree C. Within the same period of time, 5 patients with intra-abdominal recurrent gastric cancer (control group) were treated by an intraperitoneal administration of MMC 10 mg combined with surgery. These 11 patients had malignant peritoneal effusion and, although in 3 of the control group, ascitic effusion did re-accumulate rapidly soon after surgery, the 6 patients of IPHP group did not re-accumulate post-hyperthermically. The average survival duration of IPHP group is 13.6 +/- 10. 6 months, whereas that for controls is 3.0 +/- 2.1 months. Again, the survival rate for IPHP group surpassed that for controls at p = 0.012 and p = 0.008, in a generalized Wilcoxon method and Logrank method, respectively. Post-hyperthermically, hypoproteinemia and thrombocytopenia occurred transitorily. These results show that IPHP using MMC combined with surgery is a safe, reliable treatment for patients with peritoneal recurrence due to gastric cancer.     

The role of HLA-DR4 in the long-term prognosis of IgA nephropathy

The study was performed to clarify the relationship between the long-term prognosis of IgA nephropathy and the HLA-DR4 antigen. From the 130 patients typed for HLA antigens, stable (n = 42) and progressive (n = 45) patient groups were selected. DR4 frequency was not different in the two groups (stable, 66.7 vs. progressive, 53.3%). However, the frequencies of HLA-DR4 and B35 in the 130 patients were significantly higher than those in the national control (DR4; 60.0 vs. 41.6%; B35:30.0 vs. 15.5%). We concluded that DR4 played no role in the long-term prognosis of IgA nephropathy, but that B35 and DR4 were associated with the disease in the Japanese population.     

A new strategy for management of retroperitoneal tumors with supradiaphragmatic vena caval thrombi

A new surgical technique to treat retroperitoneal tumors with supradiaphragmatic vena caval invasion is described. In this technique, hepatic warm ischemia can be avoided with reversed hepatic outflow through the portal vein and neither hypothermic circulatory arrest nor cardiopulmonary bypass is necessary using centrifugal blood pump-driven bypass.     

Developmental toxicity potential of grayanotoxin I in mice and chicks

Developmental toxicity potential of grayanotoxin I (GTX I), a toxic diterpenoid contained in plants of the family Ericaceae, with sodium ionophore activity, was studied in mice and chicks. In mice, intraperitoneal injections of 1.5 mg GTX I/kg body weight of mouse for three consecutive days during the organogenetic period caused some dams to die, but neither embryotoxicity nor teratogenicity was detected. In chicks, a single injection of 0.1-1.0 microgram GTX I per egg into the extraembryonic coelom on day 1.5 or 2 of incubation, or into the amnionic cavity on day 3 or 4 of incubation induced neither embryotoxic nor teratogenic signs, but 10 micrograms GTX I per egg showed lethal effects when applied on each of those days.     

Anorexia nervosa with neutropenia--response of neutrophils to G-CSF]

A 50-year-old woman with anorexia nervosa was admitted for evaluation of neutropenia (WBC 1,600/microliters). Her bone marrow was gelatinous, and myeloid cells had decreased. Homogeneous substance deposited in the marrow, stained by alcian blue (pH 2.5), indicative of acid mucopolysaccharides. CFU-G and CFU-GM were decreased in number and myeloid pool in the bone marrow also decreased. Anti-neutrophilic antibody was negative. Neutropenia may be related to myeloid hypoplasia, due to increase of acid mucopolysaccharides replacing adipose cells in the bone marrow under long-term mal-nutritional state. Neutrophils markedly increased by administration of rhG-CSF 5.0 micrograms/kg/day for 14 days without the first peak. Serum G-CSF level did not increase (less than 60 pg/ml). It is effective to administer G-CSF to anorexia nervosa with neutropenia.     

Maturation of Pulmonary Metastases of Wilms' Tumor after Therapy: A Case Report

A case is reported of Wilms' tumor associated with multiple pulmonary metastases histologically showing maturation of the tumor cells at 9 years after the resection of the primary tumor and intensive therapy. A huge tumor of a 22-month-old patient's right kidney was resected. The tumor was diagnosed as Wilms' tumor of mesenchymal type (stage 1), which consisted of predominantly immature mesenchymal tissue including rhabdomyoblasts, smooth muscle and fibrous tissue, and few blastemal and epithelial components. Intensive preoperative and postoperative chemotherapy with actinomycin D and vincristine and postoperative irradiation therapy totaling 16 Gy were carried out. The patient was regularly followed up uneventfully until 9 years after the surgery. On routine chest x ray at the age of 10 years 11 months, multiple pulmonary nodules were found. The excised nodules from the bilateral lungs disclosed similar histology, exclusively composed of dense collagen bundles and fibrocytes intermingled with mature striated muscle bundles. No immature tumor components were detected. The possible effect of intensive therapy in this maturation was stressed, although spontaneous benign differentiation of tumor cells cannot be excluded.     

Carotid body tumour: microvascular Doppler flowmeter for shunt placement

During the span of five years from October, 1987 to December, 1992, we have operated on six cases of carotid body tumours. Total excision was performed in five patients; one patient had 90% of the tumour excised. All patients had pre-operative balloon occlusion test; only one patient showed electroencephalographic changes. Three patients required intra-operative intraluminal shunts for various reasons. Microvascular Doppler flowmetery confirmed patency and correct placement of the shunt. Elective use of the intraluminal shunt is very useful for safe excision of carotid body tumours. Microneurosurgical techniques were used for all patients. There were no cerebrovascular sequelae and 25% of patients experienced cranial nerve injury. Average follow up was three years and none of the total excision patients have had recurrence of the tumours.     

Intraosseous ganglion about to cause a fracture of the glenoid: a case report

Intraosseous ganglia of the glenoid are rare, and their etiology is unknown. This report describes a case of an intraosseous ganglion about to cause fracture of the glenoid. The patient was a 61-year-old woman with a painful left shoulder with a limited range of motion. Her symptoms did not improve after non-operative treatment. Arthroscopic examination showed a cartilage defect and erosion in the posteroinferior portion of the glenoid, behind which computed tomography (CT) showed a cystic lesion of the glenoid. There was no communication between the cyst and the joint space. The patient was treated by curettage and an autogenous cancellous bone graft from the iliac crest. Two years after the operation, the patient was almost free from pain, and CT showed good integration of the bone graft.     

Cross-cultural validation of the Japanese version of the lung cancer subscale on the functional assessment of cancer therapy-lung.

BACKGROUND: The Functional Assessment of Cancer Therapy-Lung (FACT-L) questionnaire, which consists of a core questionnaire (the General Measure of FACT [FACT-G]) and a 9-item Additional Concerns comprised of a 7-item Lung Cancer Subscale (LCS), was developed in an English-speaking culture. The validation of the Japanese FACT-G was reported previously, and this report describes the cross-cultural validation of the LCS. METHODS: The Japanese version of the LCS was developed through an iterative forward-backward translation sequence used throughout the FACT Multilingual Translation Project. In evaluating psychometric performance, its construct validity was investigated with Cronbach's alpha coefficient and factor analysis. Clinical validities of a known-groups comparison and longitudinal validity were also investigated. RESULTS: The FACT-L was administered twice to 180 patients with lung cancer within 2 weeks. The Japanese LCS had borderline values for Cronbachs alpha coefficients (0.62-0.67). Factor analysis indicated that the LCS had the three dimensions of respiratory symptoms, appetite plus body weight, and clear thinking. For clinical validity, a known-groups comparison showed that the LCS could differentiate patients according to truth disclosure, as Japanese doctors sometimes do not fully inform terminally ill patients. However, responsiveness was not proved when performance status was used as an anchor, probably owing to the short interval between the administration of the two measures. CONCLUSION: The Japanese version of the LCS asked questions about multiple symptoms of patients with lung cancer, as did the original English LCS. The longitudinal clinical validity of the Japanese version should be investigated in future clinical trials.
