Renal cell carcinoma in a solitary kidney is rather rare. Wepresent a case of this condition occurring in a 50-year-oldman. He was treated by partial nephrectomy and temporary hemodialysisfor postoperative acute renal failure. Perusal of the literaturereveals that in situ partial nephrectomy, if possible, seemsto be a reasonable treatment of choice for renal cell carcinomain a solitary kidney. This is the fifth case ever reported inJapan. 相似文献

The branching and distribution patterns of the superior mesenteric artery were studied in 10 adult bullfrogs ( Rana catesbeiana ) after injection of coloured latex solution into the vasculature. The abdominal digestive organs in the bullfrog were mainly supplied by the coeliac artery and the superior mesenteric artery, both of which arose as a common trunk, the coeliacomesenteric artery, from the abdominal aorta. The coeliac artery supplied the stomach, liver, gallbladder and the pancreas, whereas the first branch of the superior mesenteric artery was the splenic artery with other branches supplying the greater part of intestine. The apex of the intestinal loop was defined as the region supplied by the trunk of the superior mesenteric artery, and its intestinal branches constituted a 'nested formation' which had the following characteristics. (1) The branches of the trunk were distributed to both sides of the apex, and the distribution regions of younger branches were located more distant from the apex than those of older branches. (2) Two branches directed towards both sides of the trunk frequently made a common stem arising from the trunk. The second branch of the superior mesenteric artery constituted a secondary trunk and its distribution region could be defined as a secondary apex, since 1 of its branches also constituted a nested formation which was distributed to both sides of the primary and secondary apices. The intestinal branches of the superior mesenteric artery were divided into 4 types on the basis of their pattern of branching and course. It is suggested that the nested formation of the superior mesenteric artery in the bullfrog is a remnant of the vascular pattern of the tadpole, which possesses a double spiral mode of intestinal convolution, probably supplied by arteries with the nested formation in a latent form. 相似文献

BACKGROUND: The purpose of the present study was to evaluate the incidence of epidural air associated with spontaneous pneumomediastinum in children. METHODS: The subjects consisted of 25 boys and 17 girls with an age range of 3-14 years (mean age: 8.5 years) who underwent chest computed tomography (CT) for evaluation of spontaneous pneumomediastinum. The CT scans and medical records were reviewed retrospectively. RESULTS: Of the 42 patients, four (9.5%) had intraspinal air on CT. The air was interpreted as epidural in every patient. The small number of patients with epidural air meant that there was no significant difference in age, gender, or clinical manifestations between groups with and without epidural air. Subcutaneous emphysema was identified in all four patients with epidural air versus 18 out of 38 patients (47%) without epidural air. The patients with epidural air did not have any neurologic symptoms. Irrespective of the presence or absence of epidural air, every patient had a favorable outcome without any serious complications. CONCLUSION: In patients with spontaneous pneumomediastinum, epidural air may be more common than was previously realized. It is suggested that an air leak may spread from the mediastinum into the epidural space via the cervical fascial planes and neural foramina. 相似文献

Abstract The intrafamilial transmission pattern of hepatitis C virus (HCV) was examined in 118 family members of 61 index patients with type C chronic liver disease using anti-HCV antibodies and HCV RNA assay. The study subjects consisted of eight parents, 49 spouses, 50 children, eight siblings and three other relatives. The positivity rates of anti-C100, anti-JCC, second-generation anti-HCV and HCV RNA were 6.8, 12.7, 12.7 and 11.0%, respectively. Positivity in one or more anti-HCV antibody assay was detected in 3/24 (12.5%) father-child pairs, 3/17 (17.6%) mother-child pairs, 2/8 (25%) sibling pairs, 6/38 (15.8%) husband-wife pairs and 2/13 (15.4%) wife-husband pairs. In spouses, positivity for anti-HCV antibody or HCV RNA was observed after 40 years of age. None of 11 spouses married < 15 years was positive for any anti-HCV assay or HCV RNA. In spouses whose age was > 50 years and duration of marriage was > 25 years, anti-HCV or HCV RNA was frequently detected (32.0%). However, when seven pairs involving four spouses, one mother-daughter pair and two sibling pairs were subtyped, the same HCV subtypes were found in only four pairs (type II in three pairs and type III in one pair). Further, the agreement rate between anti-HCV and HCV RNA was > 90%. These results suggest that intrafamilial transmission of HCV, revealed by the subtyping method, is considered lower than the percentage of positivity for anti-HCV antibodies or HCV RNA in family members of patients with type C chronic liver disease. Thus, the intrafamilial transmission of HCV seems to be quite rare and much less common than that of HBV. 相似文献

Laparoscopic adrenalectomy in patients with large adrenal tumors 总被引:4,自引:0,他引:4
YUKIO NAYA HIROYOSHI SUZUKI AKIRA KOMIYA MAKI NAGATA TOYOFUSA TOBE TAKESHI UEDA TOMOHIKO ICHIKAWA TATSUO IGARASHI KUNIO YAMAGUCHI HARUO ITO 《International journal of urology》2005,12(2):134-139
OBJECTIVES: The maximum size of adrenal tumors that should be removed by laparoscopic adrenalectomy is controversial. We conducted a retrospective comparison of the results of laparoscopic adrenalectomy between patients with adrenal tumors > or =6 cm ('large tumors') and patients with adrenal tumors <6 cm ('small tumors'). METHODS: The participants in the study were 16 patients with large tumors and 111 patients with small tumors. The patients comprised 59 men and 68 women (mean age, 49.0 years; age range, 23-79) with varying diagnoses. Of the 16 patients with large tumors, five had Cushing's syndrome, four had pheochromocytomas, six had a non-functional tumor and one had malignant lymphoma. Adrenal tumors were confirmed by hormonal assays, biochemical tests and computed tomography. Of the 16 large tumors, five tumors were on the right and 11 were on the left. RESULTS: We found no significant differences in general demographic parameters between patients with large and small tumors. The mean duration of surgery was not significantly different between two groups. (large tumors, 210 min; small tumors,175 min). The mean volume of blood loss was 212 mL for large tumors and 30 mL for small tumors (P < 0.001, significant difference). There was no significant difference in time until walking, duration of hospitalization or number of using analgesics used. The time to first oral intake of group 1 (<6 cm) was significantly shorter than group 2 (> or =6 cm). Tumor size (> or =7.5 cm) was an independent predictor of a longer operation and greater blood loss in large tumors. CONCLUSIONS: Laparoscopic adrenalectomy for large tumors was safe and minimally invasive. 相似文献

Myasthenia gravis was diagnosed on the basis of a positive Tensilon test in a 4-year-old male child with alopecia totalis. His scalp hair and eyebrows had began to disappear at the age of 10 months. No other physical abnormalities such as motor paralysis, were seen except for left ptosis and alopecia totalis. His serum titer of anti-acetylcholine receptor antibody was elevated. No immune system abnormalities (C3, C4, CH50, C-reactive protein, antinuclear antibody or lymphocyte function disorders) were detected. Although alopecia areata and alopecia totalis are sometimes present in adults with autoimmune diseases and myasthenia gravis, this association is rare in children. The present case represents the youngest patient with myasthenia gravis associated with alopecia totalis. 相似文献

BACKGROUND: Lasers are a commonly employed method of tattoo removal; however, numerous treatments are often needed and laser treatment may fail to eliminate the tattoo completely. It has been shown in animal studies that topical application of imiquimod cream, alone, fades tattoos. It is suspected that the combination of both imiquimod and laser treatment will result in enhanced tattoo pigment clearance. OBJECTIVE: The objective was to evaluate the efficacy of topical imiquimod cream as an adjuvant to laser removal of mature tattoos. METHODS: Fourteen albino guinea pigs were tattooed with black ink, then randomly assigned into two groups: one underwent sequential laser treatments with a Q-switched alexandrite laser in conjunction with triweekly applications of 5% imiquimod cream, while the other group underwent laser therapy alone. Subjects were evaluated with clinical photographs and skin biopsies after six laser treatment sessions. RESULTS: The combination laser and imiquimod treated group was clinically and histologically rated as having less pigment than the tattoos that were treated with laser alone (p=.012 and p=.047, respectively). Adjuvant imiquimod treatment had greater inflammation (p=.002) and fibrosis (p=.002) on posttreatment skin biopsies. CONCLUSION: Imiquimod appears to be a useful adjuvant to experimental laser tattoo removal in guinea pigs. 相似文献

The clinical findings and treatment of cardiovascular abnormalities in 33 patients with Noonan syndrome are reviewed. Major cardiovascular abnormalities were pulmonary valvular stenosis in 17 patients (51.1%), hypertrophic cardiomyopathy (HCM) in 11 (33.3%), and atrial septal defect in 9 (27.3%). Dysplastic pulmonary valve was seen in 6 (35.3%). Balloon pulmonary valvuloplasty was performed for 4 patients with dysplastic pulmonary valves. Two patients were successfully treated. Surgical treatment was performed in 13 patients, 11 alive and 2 died. Two patients with HCM and arrhythmia died suddenly. In conclusion, balloon pulmonary valvuloplasty should be the initial palliation for dysplastic pulmonary valve in Noonan syndrome, and HCM is the risk factor for sudden death in Noonan syndrome. 相似文献
