Isolated subcutaneous emphysema of the abdominal wall following endoscopic retrograde cholangiopancreatography.

Isolated subcutaneous emphysema without retroperitoneal perforation is a rare complication of endoscopic retrograde cholangiopancreatography (ERCP). We present the case of an 87-year-old female who developed extensive subcutaneous emphysema following ERCP for choledocholithiasis. Abdominal computed tomography showed air perfectly dissecting the abdominal wall muscle layers and no evidence of an air leak in the pleural, mediastinal, or peritoneal spaces.

Carnoy solution versus GEWF solution for lymph node revealing in colorectal cancer: a randomized controlled trial.

Purpose: This study aimed to compare the performance of two lymph node revealing solutions.

Methods: This randomized clinical trial (NTC02704988) investigated patients with colon or rectal cancer who underwent surgical resection with D2 lymphadenectomy. Specimens submitted for conventional pathological examination were randomly assigned for additional fixation with Carnoy or GEWF solution, and dissection was performed to examine the missed lymph nodes.

ADDUCTOR POLLICIS MUSCLE THICKNESS AND PREDICTION OF POSTOPERATIVE MORTALITY IN PATIENTS WITH STOMACH CANCER.

Background: Malnutrition is very prevalent in patients with gastric cancer and increases the risk of morbidity and mortality. Adductor pollicis muscle thickness (APMT) appears as an important objective, quick, inexpensive and noninvasive measure to assess the muscle compartment.

Aim: To compare APMT and other nutritional assessment methods and to correlate these methods with postoperative mortality.

Fluorescent test accurately predicts leak of ischemic colon anastomosis in rats.

Purpose:: To investigate if fluorescein fluorescent test can predict dehiscence in a model of ischemic colonic anastomosis in rats.

Methods:: This experimental controlled trial randomly assigned 55 rats to four groups. Anastomoses were performed in non-ischemic colon segments (control group) and in ischemic colon segments measuring 1, 2 or 3 cm long (groups 1, 2 and 3, respectively).

Angiotensin-converting enzyme inhibitors-induced angioedema of the small bowel mimicking postoperative complication.

Angioedema of the small bowel (ASB) is an extremely rare side effect of the angiotensin-converting enzyme inhibitors (ACEI). We present a case of ACEI-induced ASB mimicking postoperative complication. The diagnosis of ACEI-induced ASB should be considered in patients using these drugs and presenting sudden gastrointestinal symptoms and thickening of small bowel not attributable to other diseases.

Comparison of Nonablative Fractional Erbium Laser 1,340 nm and Microneedling for the Treatment of Atrophic Acne Scars: A Randomized Clinical Trial.

Background: The efficacy and safety of nonablative fractional laser for acne scars treatment has been described in several studies. Recently, microneedling treatment has been showing promising results with lower costs, quick healing time, and low risk of postinflammatory hyperpigmentation (PIH).

Objective: To compare the effectiveness and safety of nonablative fractional erbium laser 1,340 nm and microneedling for the treatment of facial atrophic acne scars.

A comparison of radical vaginal hysterectomy combined with extraperitoneal or laparoscopic pelvic lymphadenectomy in the treatment of cervical cancer.

Background: The use of radical vaginal hysterectomy in the treatment of cervical cancer is associated with lower morbidity and a similar cure rate when compared with the abdominal approach. The present study reports a case series of radical vaginal hysterectomy followed by extraperitoneal (Mitra) or video-laparoscopic (VLP) lymphadenectomy, with comparison of the 2 techniques.

Methods: Twenty-five patients with cervical carcinoma (stages IA1 to IIA) were submitted to radical vaginal hysterectomy and extraperitoneal or laparoscopic lymphadenectomy.

Transient middle cerebral artery occlusion in rats as an experimental model of brain ischemia.

Purpose: To assess a rat model of cerebral ischemia induced by occlusion of the middle cerebral artery and its effect on the area of cerebral infarction.

Methods: Brain ischemia was induced in 52 male Wistar rats by introduction of a 3-0 nylon suture into the middle cerebral artery for either 90 (n=28) or 120 (n=24) minutes. Ischemic injury volume was determined by TTC staining, digital photography and analysis with the Image J software.

Analysis of the videolaparoscopy potentiality in the surgical treatment of the bowel obstruction.

Context: Laparotomy is the gold standard treatment of patients with intestinal obstruction without response to clinical management. Nowadays, literature has been demonstrating the feasibility of videolaparoscopy in the treatment of intestinal obstruction.

Objectives: To report the clinical-epidemiological profile of patients with intestinal obstruction submitted to surgery and verify the presence of contraindications for laparoscopy.

[Evaluation of computed tomographic colonography for detection of colorectal polyps].

Background: Computed tomographic colonography has been proposed for detection of colorectal polyps instead of colonoscopy in colorectal cancer screening programs.

Aim: To evaluate the performance of computed tomographic colonography in the detection of colorectal polyps with colonoscopy used as the gold standard.

Methods: We prospectively studied 20 patients at high risk for colorectal neoplasia (14 men and 6 women; mean age, 55 years and 59 years).

Bcl-2 expression is not associated with survival in metastatic cutaneous melanoma: a historical cohort study.

Background: Programmed cell death (apoptosis) has been implicated in tumor development and may affect the metastatic potential of tumor cells. The role of bcl-2, a proto-oncogene that inhibits apoptosis, has been studied in several malignancies, including cutaneous melanoma (CM). The purpose of this study was to evaluate the immunohistochemical expression of bcl-2 in 35 regional lymph node, 28 subcutaneous and 17 visceral CM metastases, correlating the findings with patient survival.

[Pudendal neuropathy: correlation with demographic data, severity index and pressoric parameters in patients with fecal incontinence].

Background: Fecal incontinence stands for inability in maintaining the control of defecation to a socially acceptable and adequate time and place, resulting in unwanted release of gas, liquid or solid stool. The diagnosis needs multiple exams. Anorectal manometry is mandatory for this study.
