A bedside ultrasound sign ruling out pneumothorax in the critically ill. Lung sliding.

Study Objectives: To describe and evaluate an ultrasound pattern useful in the diagnosis of pneumothorax.

Design: Ultrasound examination of "lung sliding," a respiratory movement visible when investigating the chest wall.

Setting: The medical ICU of a university-affiliated hospital.

Endoscopic palliation for unresectable pancreatic carcinoma.

Endoscopic stenting has revolutionized the palliation of malignant biliary obstruction. Individuals with biliary obstruction due to pancreatic malignancy are best managed by a team approach comprising individuals with expertise in oncology, surgery, endoscopy, and radiology. The clinical value of alleviating jaundice and associated symptoms of anorexia, pruritus, and malaise cannot be overestimated.

[Esophageal squamous cell papilloma. Report of 3 cases. Diagnostic aspects].

Unlabelled: Dysphagia is not always present in patients with esophageal squamous cell papilloma, and it can be an incidental finding during gastrointestinal endoscopy of an asymptomatic patient.

Purpose: Three cases of squamous cell papilloma of the esophagus and aspects regarding diagnosis and association with human papillomavirus are presented. CASUISTIC: Two cases are male and one female what is consistent with a higher incidence showed in the literature in males.

Replication in vitro and in vivo of an equine infectious anemia virus mutant deficient in dUTPase activity.

As an important enzyme in DNA synthesis, dUTPase is present in a wide variety of organisms and viruses and has been identified as a component of the equine infectious anemia virus (EIAV) pol gene. The role of EIAV dUTPase, designated DU, in virus replication in vitro and in vivo was investigated with a recently described infectious molecular clone of EIAV. A deletion mutant that was deficient in dUTPase activity was constructed, and its replication kinetics was examined in fetal equine kidney (FEK) cells and primary equine bone marrow macrophage (EBMM) cells.

Mucin-secreting tumors of the pancreas.

Mucinous pancreatic neoplasms present diagnostic and therapeutic challenges. These tumors behave in an indolent nature, with frequent overlap of symptoms and radiographic appearance with other forms of pancreatic cysts, pseudocysts, and malignancy. Some authors propose that all mucin-producing tumors of the pancreas are variants of the same basic entity and have subclassified them on the basis of their predominant location within the pancreas.

The membrane-associated and secreted forms of the respiratory syncytial virus attachment glycoprotein G are synthesized from alternative initiation codons.

Respiratory syncytial (RS) virus synthesizes two mature forms of its attachment glycoprotein G: an anchored type II integral membrane form and a smaller form that is secreted into the medium. Here we demonstrate that these two forms are synthesized as distinct primary translation products of a single species of G protein mRNA by initiation at either of two different AUGs. Mutant cDNAs which eliminated one of the other of the two AUG codons near the 5' end of the G gene open reading frame were constructed.

Brush cytology during ERCP for the diagnosis of biliary and pancreatic malignancies.

Endoscopic retrograde cholangiopancreatography is a valuable tool in the diagnosis and management of pancreaticobiliary diseases. The diagnostic sensitivity of brush cytology is reported as between 18% and 70% for malignant bile duct or pancreatic duct strictures. We report our findings in 74 patients with pancreaticobiliary strictures who underwent ERCP.

Intensive use of general ultrasound in the intensive care unit. Prospective study of 150 consecutive patients.

Objective: To assess the impact of systematic ultrasound (US) examination in patients admitted to the ICU.

Design: An observational study of 150 consecutive patients.

Setting: A medical ICU of a University-affiliated hospital.

Delayed massive hemobilia following percutaneous liver biopsy: treatment by embolotherapy.

A patient developed delayed life-threatening hemobilia after apparently uncomplicated percutaneous needle liver biopsy. An arteriobiliary fistula demonstrated by arteriography was successfully treated by selective transcatheter arterial embolization, with Gelfoam and a Gianturco coil. The diagnosis of liver biopsy-induced hemobilia should be suspected when a postprocedure fall in hematocrit is associated with abdominal pain, hyperbilirubinemia, or unexplained gastrointestinal bleeding.

Skin petechiae and ecchymoses (vasculitis) due to anticoagulant therapy.

The appearance of petechiae and ecchymoses following anticoagulant and fibrinolytic therapy is an unusual and rare complication. The mechanism of the vasculitis is obscure but may be related to a chemical vasotoxic reaction. During anticoagulant and fibrinolytic therapy, 6 patients developed petechiae and ecchymoses which was accompanied by pain and fever.

Fournier's gangrene complicating perinal abscess: report of two cases.

Two cases of Fournier's gangrene in which toxemia and gangrene of the scrotum developed due to perianal abscesses are described. Cultures of anaerobic gram-negative Bacteroides with a mixed flora of Pseudomonas, E. coli and Proteus were obtained.

Acute myocardial infarction and arterial embolectomy.

Emboli of a main artery cause serious complications in patients suffering from acute myocardial infarction, in whom the surgical risk is high. In order to save the limb, embolectomy is indicated and should be considered. Early diagnosis and prompt surgical intervention with the use of the Fogarty catheter simplify the embolectomy procedure and enable restoration of circulation to the ischaemic limb.
