PURPOSE To explore the value of radiotherapy in C-SCLC patients, especially in those receiving a radical resection. RESULTS The differences of survivals between the postoperative radiotherapy (PORT) and non-PORT groups were not statistically significant. But analyzing the benefits in subgroups, PORT significantly improved OS (p = 0.015), DFS (p = 0.026), LRFS (p = 0.008) and DMFS (p = 0.030) ...

BACKGROUND Thoracoscopic surgery has become very popular in recent years. Conventional thoracoscopic surgery requires three or more port wounds for manipulations of endoscopic instruments. For complicated cancer surgery, more port wounds and a larger thoracotomy wound may be required due to technical reasons. We want to investigate the effectiveness of single-port thoracoscopic approach in elec...

Background: Laparoscopic cholecystectomy is performed either by four port or three port. Although the overall patient outcome has been studied with comparable results, surgeon’s stress level has not been addressed commonly. Objective: To compare the difference in surgeon’s physical and mental stress between three port and four port laparoscopic cholecystectomy. Methods: This prospective randomi...

BJECTIVES To report an initial clinical urologic experience with a new laparoscopic access port (R-Port) and the advent of the single-port access (SPA) procedure and one-port umbilical surgery (OPUS). ETHODS Five patients underwent therapeutic laparoscopic interventions (two simple nephrectomies for end-stage kidney disease consequent to stone disease, one orchidopexy, one orchidectomy, and one...

PURPOSE To investigate the impact of modern postoperative radiotherapy (PORT) on overall survival (OS) for patients with N2 non-small-cell lung cancer (NSCLC) treated nationally with surgery and adjuvant chemotherapy. PATIENTS AND METHODS Patients with pathologic N2 NSCLC who underwent complete resection and adjuvant chemotherapy from 2006 to 2010 were identified from the National Cancer Data...

A simple but rigorous analysis of the important sources of noise in homodyne detection is presented. Output noise and signal-to-noise ratios are compared for direct detection, conventional (one-port) homodyning, and two-port homodyning, in which one monitors both output ports of a 50-50 beam splitter. It is shown that two-port homodyning is insensitive to local-oscillator quadrature-phase noise...

Phakomatosis Pigmentovascularis (PPV) is a rare cutaneous congenital malformation syndrome, defined as simultaneous occurrence of congenital cutaneous vascular and pigmentary anomalies. As most of the reported cases are from Far East countries, especially Japan, we reported a case of PPV type IIa in an Iranian patient. This case was unusual because of the coexistence of unilateral extensive por...

OBJECTIVE The advantages and disadvantages of minimally invasive Port Access mitral valve operation have not been defined relative to standard median sternotomy. A study was therefore designed to delineate differences in outcome from mitral operation via Port Access versus sternotomy in comparable patients. METHODS The records of 41 consecutive patients undergoing isolated mitral valve replac...

INTRODUCTION Invasive micropapillary carcinoma (IMPC) of the breast poses a high risk of locoregional recurrence, and postoperative radiotherapy (PORT) may be beneficial in IMPC. Hence, we determined the clinical value of PORT in IMPC patients. PATIENTS AND METHODS We assessed clinicopathological factors extracted from the Surveillance, Epidemiology, and End Results database (2004-2013). Univ...

After decades of centralization and government control, port infrastructure development and provision of services in Mexico are being transferred to the private sector. As the country prepares to enter the 21st century, port infrastructure will play a key role in strengthening and diversifying Mexico's international trade. The commitment to port improvement should remain strong despite currentl...
