"Essential laboratory tests" advocated by Japan Society of Clinical Pathology were simultaneously performed with the history taking of the present illness and the physical examination in 1,026 new patients visited the outpatient unit of Comprehensive Medicine, National Defense Medical College. We have analyzed the usefulness of the "essential laboratory tests" for the establishment of the initial diagnosis in evaluable 750 patients by comparing the diagnosis made only by the history taking and the physical examination (tentative initial diagnosis) with that included the results of these laboratory tests. The "essential laboratory tests" had contributed to remarkably increased incidences of metabolic and endocrine diseases, liver or biliary tract diseases, renal and urinary tract diseases and anemia after the application of these tests. The initial diagnoses of 61 patients were successfully established by the addition of the "essential laboratory tests" among 157 cases of which tentative initial diagnoses remained undetermined. These tests confirmed the tentative diagnoses in 78 patients, while 78 tentative diagnoses were negated and corrected after evaluation of the results of these tests. Furthermore, the diagnostic tests such as CRP and leukocyte count were useful for the estimation of the nature or degree of seriousness of the disease in 57 patients. In addition, other diseases not related to the patient's chief complaint could be detected in 238 patients (303 total number of diseases) by these tests. These results indicate the usefulness of the "essential laboratory tests" not only for the establishment of more accurate initial diagnosis but also for the screening of the "hidden" diseases such as hyperlipidemia and liver dysfunction.  相似文献

Cyclin‐dependent kinase 4 and 6 (CDK4/6) plays an important role in cell cycle progression, and the CDK4/6–cyclin D1 complex controls the cell cycle transition from G1 phase to S phase. CDK4 is enhanced in several types of cancers and CDK4/6 inhibitors attenuate the proliferation of several types of cancer in vitro/in vivo. The purpose of our study was to investigate the expression pattern of CDK4 and evaluate its clinical importance in extramammary Paget's disease (EMPD). Almost all EMPD tissues were positive for CDK4, and metastatic lesions had a similar immunostaining intensity to primary lesions. In addition, CDK4 protein levels were positively correlated with those of cyclin D1 protein. Taken together, CDK4 may assume a crucial role in EMPD progression.  相似文献

Extract of exocrine pancreatic cancer associated with humoral hypercalcemia of malignancy was examined for biological activities of PTH-like factor and transforming growth factor (TGFA and TGFB), both of which are possible causes of hypercalcemia. The crude extract had both PTH-like and TGF activities. On Bio Gel P-60 column chromatography, PTH-like and TGFA activities were eluted at around 10 kD, whereas TGFB activity was eluted at around void fractions, 10 kD and 6 kD. Liver extract, used as a control material, exhibited only TGFB activity at around 6 kD. CM-cellulose column chromatography of 10 kD fractions resulted in a subtle distinction between PTH-like activity and TGF activities. Further fractionation of the peak with PTH-like activity on reverse-phase high performance liquid chromatography separated PTH-like activity distinctly from TGFB activity. TGFA activity was lost through the procedure. It was concluded that the exocrine pancreatic cancer associated with hypercalcemia produced not only PTH-like activity but also TGFA and TGFB activities. Several chromatographic analyses suggested that PTH-like activity and at least TGFB activity stem from distinct molecules and that the PTH-like factor has no significant TGFB activity intrinsically.  相似文献

A 58-year-old Japanese man was brought to the emergency room due to disturbance of consciousness. He regained consciousness on the day of admission and started taking hospital meals, but he needed intravenous glucose administration for eight days. The total amount of glucose administration was 4,464 g. It took over three weeks for exogenous insulin to be almost undetectable. While degludec binds to albumin and exerts glucose-lowering effects for a long time, the above-mentioned period of three weeks was consistent with the half-life of albumin. Hypoglycemia induced by massive dose of insulin degludec is persistent and prominent.  相似文献

We performed phase I study of FK 435, a new antiestrogen, in 30 patients with advanced breast cancer. Slight to moderate adverse reactions were noted as follows. Single-dose study: anorexia, nausea, lassitude in one patient (80 mg), decreased serum calcium in one (160 mg), redness, tenderness in one, facial flushing, hot flushes, headache in one (320 mg). Repeated-dose study: anorexia, nausea in one patient (40 mg/day), anorexia, diarrhea, increased FSH in one, increased PRL in one (80 mg/day). FK 435 was well tolerated. Tmax was 3-5 hours, T1/2 about 25 hours. Most of FK 435 was excreted into urine as glucuronide.  相似文献
