Primary perianal actinomycosis is rare. Sporadic cases, with lesions varying in extent have been reported. The infection is caused by the bacterium Actinomyces, which often is a saprophyte. Male gender and diabetes are risk factors, but the exact pathogenic mechanism remains speculative. The diagnosis is a challenge and often delayed, with a protracted(More)
Adiponectin possesses anti-inflammatory, insulin-sensitizing and anti-atherosclerotic properties. The aim of this study was to assess the levels of serum adiponectin in patients with chronic viral hepatitis C and B and correlate them with parameters exploring insulin resistance and indices of chronic liver disease. Seventy-two patients with chronic(More)
Patients with slow transit constipation frequently have delayed gastric emptying. In animals rectal distensions inhibit gastrointestinal motility. In healthy volunteers isovolumetric rectal distensions delay upper gut transit. The purpose of this study was to determine the effect of continuous isobaric rectal distension on gastric emptying and oro-cecal(More)
Intracapsular clear crystalline lens extraction and intraocular lens (IOL) implantation were performed in 4 highly myopic eyes of 2 patients with Marfan's syndrome. One eye of each patient received an anterior chamber IOL and the other, a scleral-fixated posterior chamber IOL. The preoperative spherical equivalent ranged between -14.50 and -28.00 diopters(More)
BACKGROUND Polyethylene glycol 3350 increases stool frequency and accelerates colonic transit. Used as a laxative, it proved effective in patients with normal and slow transit. Although free of severe side effects, it may cause nausea and vomiting. The effect of this substance on upper gut transit has not been studied. AIM To investigate the effect of(More)
AIM To assess the value of Gray scale (GS) and Colour Doppler Ultrasonography (CDU) in differentiating the progression of chronic viral hepatitis (CVH) and compensated liver cirrhosis (CIR). PATIENTS AND METHODS Seventy-two patients and 32 normal individuals used as controls were studied. Forty-four patients suffered from CVH and 28 from CIR. All patients(More)
PURPOSE Human papilloma virus infections of the anogenital region are very common and cause condylomata acuminata; cervical, penile, vulvar, or perianal intraepithelial neoplasia; and more rarely, invasive cancer. The currently available therapies often result in painful, extensive, slow-healing ulcerations and frequent early relapses. This study was aimed(More)
OBJECTIVES To compare the clinical efficacy of two formulations (alcohol and alcohol free) of 0.2% chlorhexidine (CHX) rinses on plaque, gingivitis and discoloration of teeth. METHODS This double-blind crossover study consisted of one group of 10 volunteer dental students that followed two 21-day experimental gingivitis test periods. During these periods,(More)
PURPOSE We evaluated the effective irradiation parameters for photodynamic thrombosis of experimental corneal neovascularization enhanced by simultaneous hyperbaric oxygenation. METHODS Neovascularization was provoked in both eyes of each of 35 albino rabbit corneas using the intracorneal suture technique. The lasered animals were divided in 3 groups.(More)
PURPOSE This paper presents the results of the last seven years with LASIK for the treatment of myopia. METHODS 4170 eyes of 3163 patients with a mean preoperative spherical equivalent--9.66 diopters were submitted to LASIK. The eyes were divided in three groups according to the preoperative refraction: Group A (-5 to 10D), group B (-10 to 16D) and group(More)
