Pediatric Crohn's Disease in the Upper Gastrointestinal Tract: Clinical, Laboratory, Endoscopic, and Histopathological Analysis.

Crohn's disease (CD) is a progressive, multifactorial, immune-mediated disease characterized by chronic inflammation of any part of the gastrointestinal (GI) tract. Pediatric patients present with a more extensive form of the disease, especially in the upper GI tract with various histopathological inflammatory patterns. Our study aims to analyze the clinical, laboratory, endoscopic, and histopathological findings in children with diagnosed CD and compare results on the initial and follow-up tests.

The Usefulness of the Eosinophilic Esophagitis Histology Scoring System in Predicting Response to Proton Pump Inhibitor Monotherapy in Children with Eosinophilic Esophagitis.

Background: Eosinophilic esophagitis (EoE) is an immune-mediated esophageal disease with rising incidence. While proton pump inhibitors (PPIs) are the first-line treatment, a significant proportion of patients do not respond. This study aimed to determine if the EoE Histology Scoring System (EoEHSS) can predict PPI responsiveness.

Pediatric appendicular actinomycosis: a case report and literature review.

Background: Actinomycosis (ACM) is a rare infectious granulomatous disease caused by Actinomyces, a Grampositive, filamentous, saprophytic bacteria. There are several types of pediatric ACM, such as orocervicofacial (55%) and other less common forms: abdominopelvic and thoracic. We report a case of a 16-year-old who presented with abdominal ACM in the setting of acute appendicitis.

Comparison of Repetitive Cardiac Output Measurements at Rest and End-Exercise by Direct Fick Using Pulse Oximetry vs. Blood Gases in Patients With Pulmonary Hypertension.

Exact and simultaneous measurements of mean pulmonary artery pressure (mPAP) and cardiac output (CO) are crucial to calculate pulmonary vascular resistance (PVR), which is essential to define pulmonary hypertension (PH). Simultaneous measurements of mPAP and CO are not feasible using the direct Fick (DF) method, due to the necessity to sample blood from the catheter-tip. We evaluated a modified DF method, which allows simultaneous measurement of mPAP and CO without needing repetitive blood samples.

[Ultrasound, computer tomography and angiography in the diagnosis of dissecting aortic aneurysm].

The findings obtained by ultrasound, CT and angiographic examinations of 75 patients with dissecting aortic aneurysms operated on at the M.M.A.

[Secondary perforation of the colon in a patient with blast injury of the abdomen--case report].

The patient was admitted to the M.M.A.

[Pathophysiologic reactions in sheep to blast waves from detonation of aerosol explosives].

In the controlled field experiments 18 sheep were exposed to the detonation of the aerosol explosive generating the blast wave necessary to produce death in 50% of cases. The time of death and characteristic damages on the predilection sites of some organs are interpreted as blast type injuries. General response of the body to blast wave was similar to the one produced by other etiological factors.

[The site for esophageal transection in the treatment of hemorrhage from dilated esophageal veins].

Esophageal stapler transection was performed in 15 patients with bleeding from the dilated esophageal veins in the period 1984-1988. In 7 patients operated on as urgent cases due to prolonged uncontrolled bleeding, the mortality was high--71.4%, contrary to the group of electively operated patients in whom the mortality was 12.

[Study of the mechanism of injuries due to high velocity projectiles].

In the experiments on pigs wounds on the muscle-connective tissues of the thighs were made at 50 meter range by projectiles of military Rifles M 48, M 70, M 16A FAL (the length of the wound canal from 214 to 228 mm), M 91/30 and Dragunov (the length of the wound canal from 160 to 164 mm). The mass of tissue excised at primary surgical debridement was taken as a criterium of the primary devitalization of tissue, the amount of the transferred energy was calculated as well as other parameters of the terminal ballistics. Shooting through the glycerine-soap blocks under the same conditions were parallelly performed.
