Symptoms of hyponatremia and diuresis due to cerebral salt wasting syndrome (CSWS) are often observed after aneurysmal subarachnoid hemorrhage (SAH). Inadequately treated CSWS is known to work as a trigger of symptomatic vasospasm in SAH patients. Therefore, it is indispensable to detect and treat CSWS as early as possible in ICU. A 36-year-old man with SAH was admitted to our ICU. His urine volume increased excessively 3 days after ICU admission, and it reached a peak (39,250 ml x day(-1)) on the 6th day in ICU. Since infusion volume was controlled with regard to daily urinary output, hyponatremia was not noticeable and excessive urine volume stood out conspicuously. Though vasopressin and desmopressin were administered, the symptoms of natriuresis and hyponatremia were aggravated, associated with hyper secretion of natriuretic peptides (ANP 160 pg x dl(-1), BNP 172 pg x dl(-1)). Recent studies revealed that hyponatremia and hypovolemia following SAH might be caused by exaggerated secretion of natriuretic peptides. Experimental studies showed that the administration of vasopressin and desmopressin cause excessive secretion of natriuretic peptides under the circumstance of volume expansion in rats. We infer that the administration of vasopressin and desmopressin to our patient deterionated natriuresis in CSWS as in the previous experimental findings. 相似文献

OBJECTIVE: To assess the feasibility and safety of radiofrequency ablation (RFA) with hand-assisted laparoscopic surgery (HALS) for hepatocellular carcinoma (HCC) in the caudate lobe with severe liver dysfunction. SUMMARY BACKGROUND DATA: HCC in the caudate lobe remains one of the most difficult locations where various treatments tend to pose problems regarding the optimal surgical approach. The technique of HALS has thus been proposed as a useful method for performing a safe RFA therapy. For this study, we assessed the feasibility and safety of RFA with HALS for the treatment of HCC in the caudate lobe with liver dysfunction. PATIENTS AND METHODS: Between July 1999 and February 2005, 5 patients who suffered from HCC in the caudate lobe were indicated for RFA. The percutaneous puncture was difficult and all patients have severe liver dysfunction with viral chronic hepatitis. Therefore, RFA was assisted by an inserted hand through a minimal skin incision under laparoscopic inspection. An intraoperative endoscopic ultrasound examination was performed before RFA to determine the tumor region. The hand-assisted minimal dissection around the caudate lobe was required to detect tumor and avoid injuries of other tissues. RFA for HCC was performed using a cooled-tip (Radionics Inc, Burligton, MA) connected to a RF generator under the programmed cyclic impedance. RESULTS: The surgical procedures consisted of 5 RFA to tumors in the caudate lobe with HALS, which was performed safely, and a postoperative computed tomography scan revealed a sufficient ablation in all patients. There was no operative mortality but 1 patient had minor bile leakage, which was treated conservatively, and all patients recovered and thus were eventually discharged. One patient had local recurrence after 3 months, 3 patients had tumor recurrences in another segment after 6 months. At a mean follow-up 32.2 months, all patients were still alive. CONCLUSIONS: RFA with HALS is considered to be a safe and feasible technique for HCC in the caudate lobe with liver dysfunction. 相似文献

We report patients with advanced Stage IV gastric cancer responding to chemotherapy with S-1 or UFT. Case 1: The patient was a 59-year-old man with Stage IV gastric cancer because of CY 1. After surgery, chemotherapy with S-1 (100 mg/body/day) was performed for one year and 11 months. At present, 5 years and 5 months after surgery, this patient shows no signs of tumor recurrence. Case 2: The patient was a 68-year-old woman with Stage IV gastric cancer because of P 1. She was treated with 200 mg/day of UFT for one year and 9 months. At present, 5 years after surgery, she shows no signs of tumor recurrence. We considered that the longterm survival of such patients is attributable to chemotherapy with S-1 or UFT. The OPRT activity of the two cases was high, so chemotherapy with S-1 or UFT was thought to be effective for them. 相似文献

Transcatheter arterial embolizations of severe arterioportal shunt (A-P shunt) were performed with steel coils in 3 patients with hepatocellurlar carcinoma (HCC) as shown below. Case 1: A 56-year-old man with HCC associated with portal hypertension (esophageal varices and ascites abnominal pain), portal vein tumor thrombus and severe A-P shunt was performed in critical conditions. Case 2: A 51-year-old man with HCC, lung and adrenal gland metastases was accompanied with severe portal hypertention caused by A-P shunt and was in a harmful condition similar to case 1. Case 3: A 68-year-old woman with HCC associated with autoimmune hepatitis was performed a hepatic resection. Then multiple intrahepatic recurrences appeared 6 months later. A-P shunt made impossible to detect the feeding artery of tumor. After embolization of A-P shunt, esophageal varices and ascites resolved, and abdominal pain improved in cases 1 and 2. In addition, embolization enabled to perform transcatheter arterial chemoembolization in case 3. This procedure is a useful tool to improve various symptoms due to A-P shunt and to continue treatments for HCCs. 相似文献

There is no clinical disorder in partial Budd-Chiari syndrome or in a major hepatic vein ligation in hepatic trauma. When considering these findings, it is significant to investigate hepatic subsegmentectomies in which a major hepatic vein is sacrificed. We performed such hepatic subsegmentectomies in nine cases of hepatocellular carcinoma. With the sacrifice of the right hepatic vein, S7, S8 resection was done in three patients, S7 resection in two patients, S8 resection in one patient, and S5 resection in one patient. With the sacrifice of the middle hepatic vein, S8 resection was done in two patients. These resections were successfully performed with no postoperative problem. Further, there were no significant differences in postoperative liver function tests of the patients from those of a control group of the commonly performed systematic segmentectomy and subsegmentectomy. By performing such resections, resection was made possible in three cases and curative resection was made feasible in six cases. 相似文献

This study is an anatomical investigation of the angular branch of thoracodorsal artery, and examines the possible range of clinical targets for pedicled vascularised scapular bone graft. Forty-six cadavers were studied. The blood vessel length was calculated, and the distance required to reach the distal humerus from the lower end of the articular surface of the humeral head as reference point was compared with bone length. The length from reference point was an average of 121.7 mm. It was thought that the maximum distance to arrive in reference point to the distal humerus was a total of blood vessel length and transplantation bone length, which was an average of 246.3 mm. This was longer than the average of 240.8 mm of bone length from reference point to humeral medial condyle. This study had confirmed that a pedicled vascularised scapular bone graft using the angular branch could be transplanted to the distal humerus. 相似文献

l ‐tri‐iodothyronine (3, 3', 5–triiodothyronine; T3) is an active form of the thyroid hormone (TH) essential for the development and function of the CNS. Though nongenomic effect of TH, its plasma membrane–bound receptor, and its signaling has been identified, precise function in each cell type of the CNS remained to be investigated. Clearance of cell debris and apoptotic cells by microglia phagocytosis is a critical step for the restoration of damaged neuron‐glia networks. Here we report nongenomic effects of T3 on microglial functions. Exposure to T3 increased migration, membrane ruffling and phagocytosis of primary cultured mouse microglia. Injection of T3 together with stab wound attracted more microglia to the lesion site in vivo. Blocking TH transporters and receptors (TRs) or TRα‐knock‐out (KO) suppressed T3‐induced microglial migration and morphological change. The T3‐induced microglial migration or membrane ruffling was attenuated by inhibiting Gi/o‐protein as well as NO synthase, and subsequent signaling such as phosphoinositide 3‐kinase (PI3K), mitogen‐activated protein kinase (MAPK)/extracellular signal‐regulated kinase (ERK). Inhibitors for Na+/K+‐ATPase, reverse mode of Na+/Ca2+ exchanger (NCX), and small‐conductance Ca2+‐dependent K+ (SK) channel also attenuated microglial migration or phagocytosis. Interestingly, T3‐induced microglial migration, but not phagocytosis, was dependent on GABAA and GABAB receptors, though GABA itself did not affect migratory aptitude. Our results demonstrate that T3 modulates multiple functional responses of microglia via multiple complex mechanisms, which may contribute to physiological and/or pathophysiological functions of the CNS.
