[Omental infarction: CT findings (case report)].

Omental infarction, the end result of impaired perfusion of the greater omentum, is an uncommon cause of acute abdominal pain. Because its clinical symptoms are nonspecific, it is usually confused with more common conditions such as appendicitis or cholecystitis. Consequently, the diagnosis is generally made intraoperatively.

[Prolonged hepatitis A: three case reports].

In this report, three patients, admitted to Ankara University Faculty of Medicine, Ibni Sina Hospital, Clinical Bacteriology and Infectious Diseases Department, with the diagnosis of acute viral hepatitis A have been discussed because of their clinical and/or biochemical relapses. Following conservative treatment and bedrest, the liver transaminases decrease to nearly normal levels but a second peak was observed later in three of the cases. Other viral, metabolic and autoimmune factors which could lead to the increase of liver transaminases were ruled out.

[Cross-sectional imaging findings in intradiverticular bladder tumors: Case report].

Neoplasms originating in bladder diverticula are characterized by early transmural invasion and a tendency for higher histopathological grades, which make prompt diagnosis and treatment crucial in these tumors. Filling defects caused by intradiverticular tumors cannot always be visualized in intravenous urography and/or cystography. Cross-sectional imaging methods including ultrasonography, computed tomography and magnetic resonance imaging have been used singly or in combination in neoplasms of the lower urinary tract.

[Pancreas divisum: Diagnostic importance of MR cholangiopancreatography].

Purpose: Pancreas divisum, non-fusion of the ventral and dorsal pancreatic ductal system, affects up to almost 10% of the population. Approximately 20% of the patients with pancreas divilsum will develop complications such as recurrent pancreatitis. In this study, we aimed to present the magnetic resonance cholangiopancreatography (MRCP) findings of pancreas divisum, evaluate its frequency in our study group and illustrate the importance of MRCP in the diagnosis of this anatomic variation.

[Case report: Cemento-ossifying fibroma of the ethmoidal sinus presenting with exophthalmos].

Cemento-ossifying fibroma is a benign fibro-osseous tumor which contains fibrous tissue and varying amounts of calcified tissue resembling bone, cementum or both. The tumor is frequently seen in the mandibula and maxilla, but it may rarely affect the ethmoidal sinus. In this report, CT findings of cemento-ossifying fibroma located in the ethmoidal sinus are presented.

By using modified tube adherence test, 53 (15.

[Case report: psoas abscess due to brucellosis].

Skeletal system involvement is relatively a common complication of human brucellosis. However, muscular involvement is less frequent, and particularly psoas abscess is always secondary to spondylitis. In this case report, psoas abscess formation in a 70 years old female brucellosis patient complicated with spondylitis on vertebral corpus, has been presented.

[Case report: a brain hydatid cyst].

Hydatid cyst is a zoonotic infection caused by larval stage of Echinococcosis granulosus. Although any organ may be involved, bone, brain and heart involvements are uncommon. The brain involvement rate varies from 1% to 3% in hydatid disease.

[Penicillin tolerance in group A beta-hemolytic streptococci isolated from throat cultures of children with tonsillopharyngitis].

The most common bacterial cause of tonsillopharyngitis is group A beta-hemolytic streptococci (GABHS) and penicillin is the drug of choice for the treatment of these infections. However, a disturbing trend toward penicillin failure has developed in some communities. It has been proposed that penicillin tolerance is a possible explanation for this failure.

[In vitro sensitivity of methicillin-resistant Staphylococcus aureus to fusidic acid and trimethoprim-sulfamethoxazole].

In this study, a total of 225 methicillin resistant Staphylococcus aureus strains isolated from various clinical specimens (114 wounds, 27 blood, 16 of each catheter and sputum, 14 throat swabs, 10 tracheal aspirates, 7 of each urine and drain materials, 6 pleural fluids, 5 graft materials, 2 cerebrospinal fluids, 1 ascitis fluid) of hospitalized patients, were tested in-vitro for their susceptibilities to fusidic acid and trimethoprim-sulfamethoxazole (TMP-SMX) by disk diffusion method. Two-hundred-eighteen (96.9%) of isolates were found susceptible to both fusidic acid and TMP-SMX, 4 (1.

[Case report: brucellosis complicated by epididymo-orchitis and paravertebral abscess].

Brucellosis which is a zoonotic infection involving many systems, is widespread in Turkey. Although muscular and skeletal system involvements are common, genitourinary system complications (epididymo-orchitis) are observed rarely. Brucellosis accompanied by abscess formation in the vertebra is generally seen in the elderly and patients with chronic diseases, while epididymo-orchitis in young patients.

[Case report: evaluation of two cases of tuberculoma incident to tuberculosis meningitis].

Intracranial tuberculoma is one of the most serious complications of tuberculous meningitis. In this report, two patients who develop intracranial tuberculoma as a complication of tuberculous meningitis have been presented. The first patient was a 35 years old male patient who were still been in therapy for cavitary tuberculosis.

[Hepatitis A and hepatitis E seroprevalence in adults in the Ankara area].

In this study, between the period of September 2000 to July 2001, hepatitis A virus (HAV) IgG antibodies and hepatitis E virus (HEV) total (IgG + IgM) antibodies have been searched by using commercially provided enzyme immunoassay kits (Axsym, Abbott USA), in 1046 adults aged between 15-75 years old (mean age: 32.3 years), who were admitted to the outpatient clinics of Internal Medicine and Infectious Diseases Department of Ankara University Medical School, with no acute hepatitis signs and symptoms. As a result, anti-HAV and anti-HEV seropositivities were detected in 914 (87.

Comparison of protein patterns by numerical methods revealed differences between C. fetus ssp.

Seminal arginase activity in infertility.

Arginase (Arg) activity in seminal plasma and sperm cells from infertile men and healthy fertile donors was measured. There were no statistically meaningful differences in seminal plasma Arg activity between the two groups whereas sperm cells from oligospermic infertile men had a higher Arg activity compared with the controls. Some important correlations were established between sperm count and Arg activity (negative values) and sperm motility and Arg activity (positive values) in both sperm cells and plasma samples from infertile men.

Impaired endothelium-dependent and neurogenic relaxation of corpus cavernosum from diabetic rats: improvement with L-arginine.

This study describes the relaxant response to acetylcholine, electrical field stimulation and sodium nitroprusside after contraction by phenylephrine (10(-5) M) in corpus cavernosum from control and diabetic rats. The response to acetylcholine (10(-9)-10(-3) M) and electrical field stimulation (0.5-64 Hz) is decreased and can be restored by the addition of nitric oxide synthetase substrate, L-arginine(10(-5) M).
