Hemangiopericytoma arising from the wall of the urinary bladder.

Hemangiopericytoma (HPC) arising from within the urinary bladder is exceptionally rare. A 45-year-old man having the symptoms of left groin pain, vague suprapubic discomfort and frequency was admitted to our clinic. Pelvic tomography revealed a tumor in the bladder wall measuring 4 x 3 cm and was not clearly distinct from the lower abdominal wall.

Acquired perforating dermatosis: clinicopathological features in twenty-two cases.

Background: The term of acquired perforating dermatosis (APD) comprises the perforating dermatoses occurring in adult patients. Clinical and histological features of the disease are not uniform, and may resemble any of the four classic perforating disorders: elastosis perforans serpiginosa, reactive perforating collagenosis, perforating folliculitis or Kyrle's disease. Chronic renal failure and/or diabetes mellitus usually accompany this skin disease.

The relationship between ACE insertion/deletion polymorphism and coronary artery disease with or without myocardial infarction.

Objectives: Presence of the D allele or homozygosity for the deletion (D) allele of the angiotensicen-converting enzyme (ACE) insertion/deletion (I/D) polymorphism has been discussed as potent risk factor for coronary artery disease (CAD) and myocardial infarction (MI). The D allele is associated with higher levels of circulating ACE and therefore may predispose one to cardiovascular damage.

Design And Methods: The study presented here was performed to investigate the association between the ACE genotype and ACE levels.

A comparison of teledermatology using store-and-forward methodology alone, and in combination with Web camera videoconferencing.

We compared the diagnostic accuracy of conventional asynchronous teledermatology ('store-and-forward' [SAF]) with a combined technique, in which SAF methodology was used first, followed by a videoconference using low-cost Web cameras. The study involved 228 patients with 242 lesions. For each case, two independent teledermatologists (A and B) evaluated digital images and clinical information by the conventional SAF method and gave a single diagnosis.

Levels of serum hyaluronic acid, TNF-alpha and IL-8 in patients with nonalcoholic steatohepatitis.

Background/aims: Nonalcoholic steatohepatitis (NASH) is a common cause of liver disease that comprises a wide spectrum of liver damage, ranging from simple steatosis to steatohepatitis. The aim of this study is to investigate serum hyaluronic acid (HA), TNF-alpha, IL-8 levels in patients with non-alcoholic steatohepatitis and to assess their potential value as a noninvasive marker for the severity of histopathology.

Methodology: Twenty-eight patients with biopsy-proven NASH, 14 patients with cirrhosis and 15 healthy controls were studied.

Treatment of uremic pruritus with narrowband ultraviolet B phototherapy: an open pilot study.

We report the results of a pilot study of narrowband ultraviolet B phototherapy for the treatment of 20 patients with uremic pruritus. Ten patients completed the 6-week study period. A total of 8 patients were found to be responders.

Do prostatic infarction, prostatic inflammation and prostate morphology play a role in acute urinary retention?

Objective: To investigate whether there is a role of prostatic infarction, prostatic inflammation and prostate morphology in acute urinary retention (AUR) etiology.

Methods: Ninety-eight consecutive male patients who were admitted to our clinic with either AUR or lower urinary tract symptoms (LUTS) were involved in the study. Patient age ranged from 43 to 88 years (median age 70).

[Glenohumeral instability and arthrosis].

Although the development of arthrosis is rare following shoulder dislocations, it represents a significant problem if it develops after surgery for shoulder instability. The incidence of arthrosis may be decreased by correct diagnosis of the instability and appropriate surgical technique. However, should it occur, shoulder arthroplasty should be considered.

Alcock's canal releasing for pudendal artery syndrome resulting from gunshot injury.

A 21-y-old man applied to hospital with a complaint of erectile dysfunction, which started soon after a gunshot injury. The entry of the bullet was at the middle right gluteal region without any exit hole. A pelvic X-ray revealed the bullet and the scattered particles.

The effect of an angiotensin converting enzyme inhibitor on intestinal wound healing.

Background: Dehiscence of intestinal anastomosis is associated with high mortality and morbidity rates. Angiotensin II is a potent agent in the acceleration of wound repair. Angiotensin converting enzyme (ACE) inhibitors have antifibrogenic effects.

Quantitative PET studies of the serotonin transporter in MDMA users and controls using [11C]McN5652 and [11C]DASB.

(+/-)3,4-Methylenedioxymethamphetamine (MDMA, 'Ecstasy') is a widely used illicit drug that produces toxic effects on brain serotonin axons and axon terminals in animals. The results of clinical studies addressing MDMA's serotonin neurotoxic potential in humans have been inconclusive. In the present study, 23 abstinent MDMA users and 19 non-MDMA controls underwent quantitative positron emission tomography (PET) studies using [11C]McN5652 and [11C]DASB, first- and second-generation serotonin transporter (SERT) ligands previously validated in baboons for detecting MDMA-induced brain serotonin neurotoxicity.

Diagnosis of antiphospholipid syndrome during the diagnostic workup of second-trimester fetal bradycardia.

Antiphospholipid syndrome (APS) is an autoimmune disorder associated with either arterial and/or venous thrombosis (1). Two cases of APS, which were diagnosed in the second trimester during the diagnostic workup of fetal bradycardia, are presented.

Renal papillae metastasis of sigmoid colon adenocarcinoma.

Colonic carcinoma metastatic to the kidney is very rare. The usual anatomical localization for secondary renal neoplasms is the renal cortex. We report a case of sigmoid colon carcinoma with unilateral kidney metastasis localized only in the renal papillae without obvious metastatic disease.

Deep dermatophytosis caused by Trichophyton rubrum with concomitant disseminated nocardiosis in a renal transplant recipient.

Deep dermatophytosis and nocardiosis are uncommon infections. This article describes a patient who was immunosuppressed with deep dermatophytosis caused by Trichophyton rubrum and concurrent disseminated nocardiosis. The infections occurred 16 years after the patient underwent renal transplantation, and may have been related to tacrolimus therapy.

Histoacryl blue versus sutured left colonic anastomosis: experimental study.

Background: Cyanoacrylates have been advocated as a protective seal in colonic anastomosis to prevent leakage. In order to assess the effects of n-butyl-2-cyanoacrylate on left colonic anastomosis it was compared to the sutured anastomosis in the rat.

Methods: Forty male Wistar albino rats were divided into two groups of 20 each.

Does serum hexosaminidase activity play a role in the diagnosis of strangulated bowel obstruction? An experimental study.

Strangulation is associated with an increased risk of mortality and morbidity in patients with mechanical bowel obstruction. The accurate and early recognition of the presence of strangulation is important to allow safe nonoperative treatment. A number of studies have shown that there was no single and reliable test to detect or exclude the presence of strangulation.

Concomitant vitiligo and psoriasis in a patient treated with interferon alfa-2a for chronic hepatitis B infection.

Well-known cutaneous side effects of interferon (IFN)-alfa therapy include dry skin, pruritus, hair loss, and psoriasis. Presumably because of its potent immunomodulatory activity, the use of IFN-alfa has also led to the development of autoimmune diseases in susceptible individuals. Vitiligo, an autoimmune cutaneous disease, has been reported to occur during IFN-alfa therapy.
