RESUMO
Prurigo is a condition of nodular cutaneous lesions that itch intensely. Prurigo lesions are divided into acute, subacute and chronic forms that itch intensely. Subacute prurigo (SP) clinically presents as excoriated papules mostly in a symmetrical distribution on the extensor surfaces of the extremities, neck, lower trunk, and buttocks. It tends to occur in middle-aged patients, especially in women. Herein, we described prurigo simplex subacuta in a 4-year-old boy. It was histopathologically documented.

In this study we reviewed 20 patients with laryngeal squamous cell carcinoma to evaluate the oxidant and antioxidant status on tissue level. Superoxide Dismutase (SOD) and Catalase levels, two important antioxidant enzymes, and Malondialdehyde (MDA) levels, a valuable index of lipid peroxidation, were compared in cancerous and normal tissues of the patients. In cancerous tissue SOD activities were significantly lower than in the normal tissue, while there was no significant difference in MDA levels and Catalase activities. It was also observed that SOD activities significantly decreased as the histopathologic malignancy grades increased in cancerous tissue. These changes in oxidant and antioxidant status in carcinomatous tissue of the larynx are considered to be of great interest.

A comparative study has been carried out to investigate the effects of electrical stimulation and ultrasound on wound healing. Eighty-four female rats were divided into four groups depending on the treatment received. The first group was given electrical stimulation of 300 microA direct current, 30 minutes daily, starting with negative polarity and then changed after 3 days of treatment. Group 2 received sham electrostimulation treatment. The third group received 0.1 W/cm2 pulsed ultrasound using the moving applicator technique for 5 minutes a day. Group 4 received sham ultrasound treatment. A total of 7 days of treatment was given to all groups. Histopathologic and biochemical analyses on the fourth and seventh days and wound breaking strength on the twenty-fifth day were performed for all groups. By accelerating the inflammatory phase, electrical stimulation had progressed the proliferative phase of wound healing earlier than ultrasound had done. Both electrical stimulation and ultrasound have positive effects on proliferative phases, but electrical stimulation was superior to ultrasound at the maturation phase. There was no difference between the two experimental groups on the mast cell reduction effect. Although ultrasound treatment may seem to be efficient in terms of time, when the effects of electrical stimulation and ultrasound on wound healing with the methods employed in our study are considered, it is concluded that electrical stimulation is a means of treatment superior to ultrasound in wound healing.

Hibernoma is a rare type of soft tissue neoplasm originating from brown fat tissue. The present case is the first periureteric hibernoma concentrically surrounding the ureter with a concomitant renal pelvis stone.

Bronchogenic cysts are relatively uncommon congenital lesions. Because of the variability in clinical presentation and the shortcomings of diagnostic procedures, bronchogenic cysts present a diagnostic problem. This report describes a giant bronchogenic cyst that presented as a lobar emphysema in a newborn.

Polyarteritis nodosa is a rare disorder and a form of systemic vasculitis. A 48 year-old female was admitted to the hospital because menorrhagia and pelvic pain in February 1993. The patient underwent exploratory laparotomy resulting in a total hysterectomy and bilateral salpingo-oophorectomy for myoma of uterus and a right adnexal cystic mass. Histopathologic examination revealed left ovarian periarteritis nodosa. Further investigation and 9 months follow-up failed to show any systemic involvement. To our knowledge the isolated ovarian polyarteritis nodosa is the first case in the literature.
