Prevalence, Distribution and IgG Antibody Levels Associated with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Among Health-System and Community-Based Employees and Patients.

Background: Following the high morbidity and mortality due to Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infections in New Orleans, Louisiana, we sought to assess progress toward herd immunity.

Methods: Ochsner Health employees and patients who volunteered for Abbott SARS-CoV-2 immunoglobulin G (IgG) antibody test between March 1 and May 1, 2020 were included. We estimated IgG prevalence and used logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI) for variables associated with IgG test status.

Cutaneous Myiasis in Rural Haiti.

Myiasis is a disease caused by the infestation of human tissue by the larval stage of various flies. It has been identified in sub-Saharan Africa and in tropical parts of the Americas. Cases have also been identified among travelers returning to the United States.

Medicine in Society Health Project: Five Students' Journey to a Resource-Limited Clinic in the Haitian Countryside.

Background: Five medical students traveled with 4 doctors and a medical photographer to Mayaya, La Victoire, Haiti, as part of a Medicine in Society rotation to provide medical care to the indigenous population.

Methods: Preparation for the trip involved special study in identifying microbes and using blood analysis equipment; work in a clinic for underserved people in the New Orleans, LA, area; background reading; Haitian dialect classes; and development of ideas for streamlining clinic operations.

Results: During the week in country, the healthcare team saw 472 patients and made more than 1,100 diagnoses.

Imatinib mesylate-induced acute hepatitis in a patient treated for gastrointestinal stromal tumour.

We report the first case of hepatocellular injury occurring in a patient treated for metastatic gastrointestinal stromal tumour (GIST) with imatinib mesylate, with two positive rechallenges including one with 2.5% of the current therapeutic dosage. The patient could be treated later with sunitinib without liver toxicity.

[Traumatic complete isthmic rupture of horseshoe kidney].

The authors report the case of a 14-year-old boy with complete isthmic rupture of a horseshoe kidney after a bicycle accident. The imaging diagnosis was difficult because of the presence of a massive retroperitoneal haematoma. However, sonography and CT should be sufficient to detect associated signs, such as malrotation of the renal hila and low-lying kidneys.

[MRCP in the diagnosis and management of bile leak caused by blunt liver injury].

Introduction: Bile leak is a rare - and difficult to diagnose - complication of nonoperative treatment in blunt liver injury. Magnetic resonance cholangiopancreatography (MRCP) enables a positive diagnosis and localization of the biliary peritoneal fistula.

Case: We report the case of a child with blunt liver injury treated nonsurgically and subsequently complicated by bile leak.

[Seromuscularis rupture of the oesophagus after vomiting: a rare cause of hemothorax].

We report a case of seromuscularis rupture of the oesophagus occurring after an episode of vomiting and revealed by a left hemothorax. Diagnosis was established at thoracoscopy and was related to the nosologic setting of post-emetic syndromes. All unusual pleuropulmonary symptoms after vomiting must make evoke this diagnostic hypothesis.

[Metastatic obstruction of the small bowel revealing or complicating squamous-cell lung cancer. Two cases and a review of the literature].

Gastrointestinal metastasis from lung cancer is exceptional and generally asymptomatic. Other secondary localizations are often present. Metastastic dissemination may involve any portion of the gastrointestinal tract.

[Damage control laparotomy for haemorragic abdominal trauma. A retrospective multicentric study about 109 cases].

Aim Of The Study: Damage control laparotomy is a new approach to the more severe abdominal traumas. It stems from a better understanding of the physiopathology of the haemorragic shock.

Patients And Methods: A national retrospective study from 27 centers about 109 trauma patients who underwent a damage control procedure between January 1990 and December 2001, is analysed.

Laparoscopic treatment of acute small bowel obstruction: a multicentre retrospective study.

Background: Laparoscopic surgery is thought to promote early recovery and quicker return to bowel function. The objective was to evaluate the rate and predictive factors of success, the causes of failure, the morbidity, and mortality during and after hospitalization, as well as to determine whether laparoscopic treatment of acute small bowel obstruction offers the same benefits as for other laparoscopic procedures.

Methods: The records of 308 patients with acute small bowel obstruction treated laparoscopically in 35 centres between 1 October 1988 and 30 September 1996 were retrospectively reviewed.

[Intra-thymic localization of a cystic multi-tissue mature teratoma].

The authors report a case of mediastinal tumour in a child, corresponding to a teratoma arising in the thymus, an original site for this lesion classically observed in children.

Is prophylactic pelvic drainage useful after elective rectal or anal anastomosis? A multicenter controlled randomized trial. French Association for Surgical Research.

Objective: We investigated the role of drainage in the prevention of complications after elective rectal or anal anastomosis in the pelvis. Anastomotic leakage after colorectal resection is more prevalent when the anastomosis is in the distal or infraperitoneal pelvis than in the abdomen. The benefit of pelvic drains versus their potential harm has been questioned.

Prophylactic abdominal drainage after elective colonic resection and suprapromontory anastomosis: a multicenter study controlled by randomization. French Associations for Surgical Research.

Background: Only 4 controlled trials have investigated whether prophylactic abdominal drainage was of value after colonic resection. None have been able to find any statistically significant difference, but the number of patients was small and the beta error risk was high.

Objectives: To compare patients who underwent abdominal drainage with those who did not for the rate and severity of complications after elective colonic resection followed immediately by anastomosis of the suprapromontory colon and to compare suction drains with nonsuction drains.

Omentoplasty in the prevention of anastomotic leakage after colonic or rectal resection: a prospective randomized study in 712 patients. French Associations for Surgical Research.

Objective: To investigate the role of omentoplasty (OP) in the prevention of anastomotic leakage after colonic or rectal resection.

Summary Background Data: It has been proposed that OP--wrapping the omentum around the colonic or rectal anastomosis--reinforces intestinal sutures with the expectation of lowering the rate of anastomotic leakage. However, there are no prospective, randomized trials to date to prove this.

[Bilateral newborn testicular torsions].

A case of bilateral spermatic cord tension in a neonate is reported. Clinical findings are compared with those in 22 previously published cases. Obstetrical history is usually unremarkable.

[Mesenteric fibromatosis in infants. A case].

The authors report on a case of mesenteric fibromatosis in a 5 month-old infant. Surgical excision was available and the clinical course was good, without recurrence after 30 months. Clinical and histological features of mesenteric desmoïd tumor in children are discussed and diagnostic difficulties are examined in depth.
