ABSTRACT
ABSTRACT Purpose: This study aims to evaluate the oncological and functional results of open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN) at the T1b clinical stage, which constitutes 25% of renal cell carcinomas (RCC) at diagnosis. Materials and Methods: The characteristics of 63 patients with stage T1b solitary tumor who underwent OPN (41) or LPN (22) were compared. The survival analysis was performed using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were performed to determine the factors affecting disease-free survival. Potential predictive factors, which might affect the postoperative glomerular filtration rate (GFR), were evaluated using multivariate linear regression analysis. Results: No differences were observed between OPN and LPN groups regarding patient and tumor characteristics. Although the warm ischemia time, intraoperative estimated blood loss, and operation duration were higher in the LPN group, no differences were noted between the two techniques regarding complication rates (p<0.001, p=0.023, p≤0.001, and p=0.190, respectively). The median hospitalization time was shorter in the LPN group than that in the OPN group (4 and 5 days, respectively), with less severe complications. No intergroup differences were observed regarding cancer-specific survival (CSS), disease-free survival (DFS), and overall survival (OS). The evaluation of the factors affecting DFS showed that age was an effective parameter (RR = 1.112, 95% CI: 1.010-8.254), but the surgical technique was not. Conclusion: No differences were observed between OPN and LPN techniques between oncological and functional outcomes in patients with clinical stage T1b RCC.

Background: Infantile choriocarcinoma is usually fatal without appropriate treatment. Casecharacteristics: A 3-month-old boy who presented with respiratory distress, hepatomegaly,amemia and bilateral nodular lesions on chest X-ray. Observation: Fine-needle liveraspiration revealed necrotic tumour cells. The serum ?-hCG level was very high (2057 mIU/L), supporting a diagnosis of infantile choriocarcinoma of the liver. Surgical resection aftercisplatin-based multiagent chemotherapy afforded successful remission. Message: Earlytreatment of infantile choriocarcinoma can yield a successful outcome.
ABSTRACT
Pneumatosis intestinalis, in association with portal venous gas, is a rare finding in children and young adults. In radiological studies, it is characterized by gas-filled cysts within the bowel-wall. It is often a sign of the serious significant underlying illness and is associated with a poor prognosis. A case of pneumatosis intestinalis and portal venous gas associated with abdominal tuberculosis in a child is presented here. Despite responding well to anti-tubercular treatment, he died suddenly at home, two months after discharge. It is recommended that cases with pneumatosis intestinalis should be carefully observed, although symptoms appear to be improving.
