BACKGROUND Improved control of cutaneous malignancies using Mohs micrographic pathologic clearance has been well established. However, surgical margin control of advanced and complex cutaneous tumors of the head and neck is commonly performed by far less reliable frozen section margin analysis. OBJECTIVE To describe a routine and ideal collaboration between dermatologic surgery and facial pla...

We studied prospectively a consecutive series of 50 patients with chronic osteomyelitis. Patients were allocated to the following treatment groups: 1) wide resection, with a clearance margin of 5 mm or more; 2) marginal resection, with a clearance margin of less than 5 mm; and 3) intralesional biopsy, with debulking of the infected area. All patients had a course of antibiotics, intravenously f...

INTRODUCTION Basal cell carcinoma is the most common tumor of the eyelid. In this region, reconstruction is complex and damage to healthy tissue should be minimal. OBJECTIVE To define the relationship between margin clearance at excision and the recurrence rate of basal cell carcinoma of the eyelid. METHODS This prospective study was conducted with 111 patients submitted to surgery for basa...

A new species of callianassid ghost shrimp is described from the Persian Gulf, Iran. Cheramus iranicus sp. nov. is the first member of Cheramus described from Iranian subtidal waters and can be differentiated by a large cheliped with a ventroproximal spine on the merus and 7 spines on the ventral margin of the ischium, the endopod of the uropod has 4 movable spines on the distal margin and the ...

The transanal eversion and prolapsing technique is a well-established procedure, and can ensure an adequate distal margin for patients with low rectal neoplasms. Potential leakage risks, however, are associated with bilateral dog ear formation, which results from traditional double-stapling anastomosis. The authors determined the feasibility of combining these techniques with a commercial stapl...

Macrobrachium aemulum madhusoodani Pillai & Unnikrishnan (2013) was recently described based on material from the Neyyar River, Kerala, India as a new subspecies of M. aemulum (Nobili, 1906). As however, both species and subspecies names are considered part of the species-group for nomenclatorial purposes (ICZN, Art. 45.1), the name is a junior homonym of Macrobrachium madhusoodani Unnikrishnan...

The multicolored Asian lady beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), has become a popular study organism due to its promise as a biological control agent and its potential adverse, non-target impacts. Behavioral and ecological research on H. axyridis, including examinations of its impacts, could benefit from non-destructive or non-disruptive sexing techniques for this coc...

OBJECTIVE To compare laparoscopic distal pancreatectomy (LDP) versus open distal pancreatectomy (ODP) by using meta-analytical techniques. BACKGROUND LDP is increasingly performed as an alternative approach for distal pancreatectomy in selected patients. Multiple studies have tried to assess the safety and efficacy of LDP compared with ODP. METHODS A systematic review of the literature was ...

BACKGROUND Mesorectal margin tumour involvement is a predictor of local recurrence in rectal carcinoma and an indication for postoperative radiotherapy in suitable patients. However, the prevalence of non-peritonealised surgical margin involvement in ascending colon carcinoma is unknown. AIMS To test the hypothesis that retroperitoneal surgical margin (RSM) tumour involvement occurs in distal...
