Acute obstruction of a patent processus vaginalis occurred in two boys, mimicking incarceration of an inguinal hernia. In fact, obstruction was caused by an intussusception of the processus vaginalis forming an intussuscipiens that occluded the hernia sac. This lesion, described previously in 1896 and in 1974, is one of the mechanisms by which an asymptomatic hernia or hydrocele becomes acutely...

Mycobacterium ulcerans disease (MUD) is rapidly reemerging in many countries, especially in West African countries. Antecedent trauma has often been related to the lesions that characterize this frequently crippling disease. We report here the first case of MUD that followed a human bite at the site where the lesion later occurred.

A patient with neuritic leprosy developed borderline skin lesions. Later, another skin lesion developed on the left side of the forehead with clinical involvement of the supraorbital branch of the ophthalmic division of the trigeminal nerve. Simultaneously, paralysis of the occipitofrontalis and mild paresis of orbicularis oculi occurred.

This report concerns an AIDS patient presenting systemic and cutaneous manifestations of histoplasmosis. A histopathological and mycological examination of the skin lesion confirmed the diagnosis. In AIDS patients histoplasmosis arises mainly when the T-CD4+ cell count is less than 50 cells/mm3. In such cases, histoplasmosis can be severe and if left untreated can lead to death, as occurred wit...

The cerebellar infarction resulting from supratentorial craniotomy is uncommon event and its management has been controversial. After removal of space occupying lesion on right frontal area, two cases of remote cerebellar infarctions occurred. We reviewed each cases and the techniques to manage such complications are discussed. Early extraventricular catheter insertion and midline suboccipital ...

INTRODUCTION Lobular capillary hemangioma (LCH) is a benign lesion of vascular origin. It rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis. CASE REPORT In this report we present a case of LCH of the nasal cavity which occurred approximately one month after delivery. There was no recurrence after complete endoscopic resection during one ...

Sclerosing polycystic adenosis (SPA) is a rare, newly-reported lesion of the salivary glands. Most cases occurred within mayor salivary glands and were frequently confused with other salivary gland carcinomas such as acinar cell carcinoma. We report a case of SPA within the submandibular gland in a 63-year-old woman.

A paromomycin and methylbenzethonium chloride ointment cured Leishmania enriettii infections in guinea pigs. Amastigotes were totally eliminated from the treated lesion after 10 days of treatment. A delayed effect also occurred on untreated lesions in the same animals. Lesions treated at various times after infection permitted protective immunity to develop, and 90% of treated animals were refr...

Spinal serotonergic pathways provide inhibitory and excitatory modulation of sensory, autonomic, and motor processing. After spinal cord injury (SCI), the acute inflammatory response is one process that damages descending pathways. Increases in serotonergic fiber density in spinal segments rostral and decreases caudal to the lesion have been observed previously and may contribute to neuropathic...
