Sarcomatoid Carcinoma of the Maxilla: A Case Report with Literature Review.

Sarcomatoid carcinoma is a very rare malignant and aggressive tumor that can involve the maxillary sinus. We report the case of a 46 y/o male who presented a tumor of the right maxillary sinus with extension to the right nasal cavity. The diagnosis of sarcomatoid carcinoma was set by histology and immunohistochemistry.

The management of a cystic hepatic lesion ruptured in the bile ducts: a case report.

Background: Hepatic cystadenoma is a rare benign cystic tumor; it tends to recur after incomplete surgical resection and has malignant potential. We report the case of a patient with a ruptured biliary cystadenoma in the common bile duct that caused diagnostic and therapeutic problems.

Case Presentation: A 34-year-old North African woman, admitted for angiocholitis, was operated 2 months before for a hepatic cystic lesion taken for a hydatid cyst compressing her common bile duct.

IPS Interest in the EEG of Patients after a Single Epileptic Seizure.

Objective. This study aims to evaluate the incidence of pathological cerebral activity responses to intermittent rhythmic photic stimulation (IPS) after a single epileptic seizure. Patients and Methods.

Magnetic Field Interactions of Military and Law Enforcement Bullets at 1.5 and 3 Tesla.

Objectives: There are significant numbers of military and law enforcement bullets containing ferromagnetic materials. This study aimed to assess the magnetic field interactions for a representative sample of military and law enforcement ballistic objects at 1.5 and 3 tesla (T) to create a magnetic resonance imaging (MRI) compatibility database.

Contribution of the computed tomography of the anatomical aspects of the sphenoid sinuses to forensic identification.

Introduction: Body identification is the cornerstone of forensic investigation. It can be performed using radiographic techniques, if antemortem images are available. This study was designed to assess the value of visual comparison of the computed tomography (CT) anatomical aspects of the sphenoid sinuses, in forensic individual identification, especially if antemortem dental records, fingerprints or DNA samples are not available.

Adenocarcinoma arising from chronic perianal crohn's disease: a case report.

Malignant transformation of perineal fistula in Crohn's disease has rarely been reported. We report a case of Crohn's disease with recurrent perineal fistulas. A 36-year-old male, diagnosed with Crohn's disease at the age of 24, developed adenocarcinoma in an anorectal fistula that had existed for years.

An exceptional collision tumor: gastric calcified stromal tumor and pancreatic adenocarcinoma.

The authors report an exceptional case of collision tumor comprised of a gastric calcified stromal tumor and a pancreatic adenocarcinoma. The pancreatic tumor was detected fortuitously on the histological exam of resection specimen.

Successful surgical treatment of extrahepatic biliary papillomatosis diagnosed with endoscopic retrograde cholangiopancreatography: a case report.

Introduction: Biliary papillomatosis is a condition characterized by multiple papillary tumors of variable distribution and extent within the biliary tract. Papillary carcinoma can develop in these lesions. It is a rare biliary pathological entity and its clinical features and outcome are not well known.

Value of spontaneous hyperdensity of cerebral venous thrombosis on helical CT.

Background: Excluding a cerebral venous thrombosis (CVT) through imaging is a frequent request in the emergency setting. This assessment often starts by an unenhanced brain computed tomography (CT).

Purpose: Re-evaluate the value of spontaneous hyperdensity of CVT on helical unenhanced brain CT.

Sequential therapy versus standard triple-drug therapy for Helicobacter pylori eradication: a prospective randomized study.

Purpose: Eradication rates following standard triple therapy for Helicobacter pylori infection are declining. Recent studies, conducted in a number of countries, have shown that sequential therapy for H. pylori infection yields high cure rates.

Gastric bronchogenic cyst presenting as a submucosal mass: a case report.

Introduction: Bronchogenic cysts are developmental anomalies of the primitive foregut which mostly occur in the lung. Gastric bronchogenic cysts are extremely rare; few cases have been reported in the literature and the diagnosis was often made following surgical resection.

Case Presentation: A 40-year-old North African man was admitted to our hospital with a gastric submucosal mass.

Comparison between ropivacaine 1.5 mg ml(-1) plus fentanyl 2 mg ml(-1) and ropivacaine 1.5 mg ml(-1) plus clonidine 1 mg ml(-1) as analgesic solution after anterior cruciate ligament reconstruction: a randomized clinical trial.

Background: Ropivacaine is commonly used as local anesthetic for postoperative analgesia through an epidural catheter. Data show that several adjuvants influence the analgesic effect of local anesthetic potency.

Objective: The aim of the study was to compare fentanyl and clonidine as adjuvants to 1.

Transient locked-in syndrome and basilar artery vasospasm.

Background: Cerebral vasospasm is the main cause of neurological mortality and morbidity following subarachnoid hemorrhage. Basilar artery vasospasm (BAVS) is associated with a high morbidity and may have multiple clinical presentations.

Methods: We report the case of a 43 years-old man with BAVS presenting as a reversible locked-in syndrome (LIS) after stopping sedation.

A comparison between the Airtraq and Macintosh laryngoscopes for routine airway management by experienced anesthesiologists: a randomized clinical trial.

Background: The Airtraq Optical Laryngoscope is a new type of laryngoscope that provides a direct view of the glottis without alignment of the mouth, pharynx and trachea. Data show that it has advantages over the Macintosh laryngoscope.

Objective: The aim of this study was to compare the use of the Airtraq laryngo-scope versus the No.

Validation of single real-time TaqMan PCR assay for the detection and quantitation of four major genotypes of hepatitis E virus in clinical specimens.

Since the characterization of the genome of the hepatitis E virus (HEV) in 1990, a large genetic diversity has been described. A single real-time reverse transcription (RT)-PCR assay with TaqMan technology has been validated which uses only one set of primers and probe within the ORF2 HEV region (nt 5207-5292) for the detection and quantification of the four major genotypes of HEV. This assay proved to be as efficient as the conventional RT-PCR methodology for the detection of HEV in clinical samples testing positive previously.

Cerebral microdialysis and P(ti)O2 for neuro-monitoring before decompressive craniectomy.

We report the case of a young patient with post-traumatic, intractable, intracranial hypertension leading to craniectomy. This intracranial hypertension was preceded by focal signs of ischemia diagnosed through P(ti)O2 monitoring and cerebral microdialysis, and occurred a few hours prior to a decrease in cerebral perfusion pressure below 60 mmHg. The neurological outcome was satisfactory with a Glasgow Outcome Scale of 4 at 3 months.

Genetic heterogeneity of hepatitis E virus in Darfur, Sudan, and neighboring Chad.

The within-outbreak diversity of hepatitis E virus (HEV) was studied during the outbreak of hepatitis E that occurred in Sudan in 2004. Specimens were collected from internally displaced persons living in a Sudanese refugee camp and two camps implanted in Chad. A comparison of the sequences in the ORF2 region of 23 Sudanese isolates and five HEV samples from the two Chadian camps displayed a high similarity (>99.
