BACKGROUND Although rare, abdominal wall recurrences after laparoscopic surgery for cancer have been increasing at an alarming rate as the range and sheer number of laparoscopic surgical procedures have increased. Overall, 13 case reports of abdominal wall cancer recurrence after laparoscopic surgery have been published. METHODS AND RESULTS We present the(More)
BACKGROUND Pneumocystis jirovecii remains an important cause of fatal pneumonia (Pneumocystis pneumonia or PcP) in HIV+ patients and other immunocompromised hosts. Despite many previous attempts, a clinically useful serologic test for P. jirovecii infection has never been developed. METHODS/PRINCIPAL FINDINGS We analyzed serum antibody responses to the P.(More)
The technique for laparoscopic cholecystectomy (LC) was originally devised and described has remained unchanged because of its efficacy. LC involves a 10-mm trochar in periumbilical region, 10-mm trochar in the epigastrium, and two 5-mm trochars at the right anterior axillary line and right midclavicular line.

Anterior abdominal wall hernias are among the most commonly encountered surgical disease. We sought to identify risk factors that are associated with 30-day postoperative mortality following emergent abdominal wall hernia repair using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. A retrospective(More)
The study presents a method for identifying endocardial electrical features relevant to local ischaemia detection at rest. The method consists of, first, normalisation of electrograms to a uniform representation; secondly, the use of principal component analysis to reduce the dimensionality of the electrogram vector space; and, thirdly, a search for a(More)
