Electro-acupuncture Treatment for the Upper Segment Ureterolithiasis Under B-Ultrasonography

In order to explore the effects of the local strong stimulation generated by electro-acupuncture for treatment of the upper segment ureterolithiasis,a controlled study was carded out among the treatment group (electro-acupuncture with strong stimulation),the control group Ⅰ(medication) and the control group Ⅱ (conventional acupuncture).The results showed that the differences in the cure rate and the total effective rate between the treatment group and the two control groups were significant in statistical analysis (P<0.05 and P<0.01 respectively).This indicates that better therapeutic effects can be obtained by the local strong stimulation generated by electro-acupuncture for treatment of the upper segment ureterolithiasis.

Efficacy of intraductal ultrasonography in the diagnosis of non-opaque choledocholith

AIM: To evaluate the efficacy of intraductal ultrasonography (IDUS) in the diagnosis of non-opaque, common bile duct stones. METHODS: A total of 183 patients (102 males, mean age 73 years; 81 females, mean age 70 years) with suspected common bile duct stones diagnosed through abdominal computed tomography (CT), magnetic resonance imaging (MRI), and abdominal Type-B ultrasound were included in the study. The diagnosis was confirmed through endoscopic retrograde cholangiopancreatography (ERCP) followed by IDUS. RESULTS: A total of 183 patients with suspected common bile duct (CBD) stones were included in the study as follows: 36 patients with high-density CBD stones, 68 patients with sand-like stones, 44 patients with low-density stones, 21 patients with ampullary cancer, and 14 patients with pancreatic cancer. Conventional imaging revealed 124 cases of choledochectasia, and only 36 cases of suspected CBD stones; ERCP revealed 145 cases of CBD stones with three missed diagnoses. IDUS revealed 148 cases of CBD stones, 21 cases of ampullary tumors, and 14 cases of pancreatic cancer. CONCLUSION: IDUS was more effective in the diagnosis of bile duct stones than ERCP, upper abdominal CT or upper abdominal MRI.

Non-alcoholic fatty liver disease and metabolic syndrome in obese children

I read with great interest the article of Fu et al who investigated whether non-alcoholic fatty liver disease(NAFLD)is an early mediator for prediction of metabolic syndrome,and whether liver B-ultrasound could be used for its diagnosis,in a study involving 861 obese children(6-16 years old).In this study,it was reported that NAFLD is not only a liver disease,but also an early mediator that reflects metabolic disorder,and that liver B-ultrasound can be a useful tool for metabolic syndrome(MS)screening.The authors reported that NAFLD and MS were present in 68.18%and 25.67%of obese children,respectively.Moreover,they observed that the prevalence of MS in NAFLD children was 37.64%,which was much higher than that in the non-NAFLD group.Criteria analogous to those of the Adult Treatment PanelⅢdefinition for MS were used for children in this study.The reported prevalence data on MS in the young has varied markedly,in large part because of disagreement among the variously proposed definitions of MS.Therefore,in my opinion,a study aiming to assess the association between MS components and NAFLD in obese children has to take into account a simple,easy-to-apply clinical definition proposed by the international diabetes federation for MS.Interpretation of the results of the Fu et al study are limited byanother major caveat:that the diagnosis or exclusion of NAFLD was based on liver enzymes and ultrasound imaging,but was not confirmed by liver biopsy.Indeed,it is known that liver enzymes may be within the reference interval in up to 70%of patients with diagnosed NAFLD and that the full histopathological spectrum of NAFLD may be present in patients with normal liver enzymes,which therefore cannot be reliably used to exclude the presence of NAFLD.

DIAGNOSIS AND TREATMENT OF PHEOCHROMOCYTOMAS IN URINARY BLADDER

Objective To investigate the diagnosis and treatment of pheochromocytomas in urinary bladder and review relative literatures. Methods The clinical data of 6 cases of bladder pheochromocytoma were retrospectively analyzed. Bladder submucosal mass was detected by B-ultrasound in 6 cases, computerized tomography （CT） in 4, and cystoscopy in 3. All patients were treated with surgical operation. Results Two patients showed obvious fluctuation of blood pressure during operation. All patients were pathologically diagnosed as pheochromocytoma postoperatively. Five patients were followed up （from 3 months to 7 years） , and their blood pressure returned to normal. No patient had relapse and malignancy. Conclusion Typical hypertension during urination and hematuria constitute the chief symptoms of bladder pheochromocytoma. B-ultrasound, CT, and cystoscopy are the main methods for the localization of the lesions. Partial cystectomy or excision of the tumor is the preferred management and postoperative long-term follow-up is necessary.
