BACKGROUND Data on recurrence patterns following hepatectomy for colorectal liver metastases (CRLMs) and their impact on long-term outcomes are limited in the setting of modern multimodal management. This study sought to characterize the patterns of, factors associated with, and survival impact of recurrence following initial hepatectomy for CRLMs. METHODS A retrospective cohort study of pati...

BACKGROUND The aim was to evaluate the applicability of laparoscopic surgery in the treatment of primary rectal cancer in a training unit. METHODS A cohort analysis was undertaken of consecutive patients undergoing elective surgery for primary rectal cancer over a 7-year interval. Data on patient and operative details, and short-term clinicopathological outcomes were collected prospectively a...

head. Every variety of insanity may result from this exciting cause. Thus, of 482 cases of melancholiat (Lympemanie ou Melancholie), 10 or 2"0 per cent, were the result of injury to the head. Of 588 cases of mania, J 13 or 2-5 per cent, were caused in the same manner. Of 235 cases of dementia,? 3 or 1 -2 per cent, had the same origin. Injuries of the head likewise produce moral insanity?i. e., ...

The effect of pH-adjustment of three per cent 2-chloroprocaine (2-CP, Nesacaine MPF) on the onset, duration, and spread of epidural analgesia and anaesthesia was studied in patients undergoing lower extremity surgery. Forty ASA physical status I and II patients were randomized to two groups. In a double-blinded fashion, patients in both groups received an epidural injection of 15 ml of local an...

The set of all centralizers elements in a finite group G is denoted by Cent(G) and called n-centralizer if |Cent(G)|=n. In this paper, the structure non-abelian with property that GZ(G)≅Zp2⋊Zp2 obtained. As consequence, it proved such has exactly [(p+1)2+1] element commuting conjugacy class graph completely determined.

BACKGROUND Current guidelines indicate that D2 resection is the standard of care for patients with locally advanced gastric cancer. To assess the impact of quality assurance of lymph node removal, non-compliance and contamination in the D1 and D2 study arms of the Dutch Gastric Cancer Trial were investigated with respect to recurrence and survival. METHODS The location and numbers of lymph no...

Heavy metal impregnation of specimens for electron microscopy offers a means for differential "staining" of various tissue components and cellular constituents. Of many silver impregnation methods, one of the most useful is Gomori's silver methenamine (1) after periodic acid oxidation (PA-SM) (2, 3). Several authors have applied silver impregnation to electron microscopy (4-7), mainly for the d...
