Herpetic esophagitis in immunocompetent individuals is a rare entity that should be suspected clinically by an acute onset of symptoms, and without apparent cause of a symptomatic triad consisting on odynophagia, heartburn and fever. Its occurrence may be due to reactivation of a previous infection or less often a primary infection. Herpes simplex type 1 is the most common cause. Upper endoscopy establishes the diagnosis of suspicion of herpetic esophagitis. It also allows to take multiple biopsy samples and viral culture, leading to a definitive diagnosis. The severity of symptoms is related to the degree of oesophageal involvement. In immunocompromised patients treatment is indicated with acyclovir, but the indication in immunocompetent patients is controversial because the process is time, limited with a low probability of complications. We present a case of acute herpetic esophagitis in an immunocompetent host that debuted acutely with severe upper gastrointestinal tract symptoms, associated with an insidious and nonspecific onset of flu-like symptoms. Endoscopic findings showed a severe involvement in the lower third of the oesophageal mucosa.  相似文献

Chronic liver diseases (CLD) alter the kinetics of drugs. Despite dosage adjustment is based on Child-Pugh scores, there are no available recommendations and/or algorithms of reference to facilitate dosage regimens. A literature review about dose adjustment of the drugs from the hospital guide -which are included in the list of the WHO recommended drugs to be avoided or used with caution in patients with liver disease- was carried out. The therapeutic novelties from the last few years were also included. In order to do so, the summary of product characteristics (SPC), the database DrugDex-Micromedex, the WHO recommendations and the review articles from the last 10 years in Medline were reviewed. Moreover, the kinetic parameters of each drug were calculated with the aim of establishing a theoretical recommendation based on the proposal of Delcò and Huet. Recommendations for 186 drugs are presented according to the SPC (49.5%), DrugDex-Micromedex (26.3%) and WHO (18.8%) indications; six recommendations were based on specific publications; the theoretical recommendation based on pharmacokinetic parameters was proposed in four drugs. The final recommendations for clinical management were: dosage modification (26.9%), hepatic/analytical monitoring of the patient (8.6%), contraindication (18.8%), use with caution (19.3%) and no adjustment required (26.3%). In this review, specific recommendations for the practical management of patients with chronic liver disease are presented. It has been elaborated through a synthesis of the published bibliography and completed by following a theoretical methodology.  相似文献

Pure, benign epidermoid cysts of the abdominal viscera are rare. There have been only six reports of epidermoid cysts of the cecum in the literature. A 31-year-old female with a previous cesarean delivery was admitted to our hospital with inguinal pain. After admission to the hospital, she was operated with the initial diagnosis of adnexal mass. During the operation, no adnexal pathology was identified. A heterogeneous mass originated from the posterior surface of the cecum was observed. It had no connection with the lumen. The mass was then removed with dissection. Macroscopically, the mass was 9x7 cm in diameter and wall thickness was 0.1 cm. The inner and outer surfaces were smooth. It was filled with a dense yellow, thick-fatty material with no tooth, hair, bone, or calcification areas. On microscopic examination, the inner lining was composed of mature keratinized stratified squamous epithelium with a granular layer. In view of the later findings, the case was reported as epidermoid cyst of the cecum. Although epidermoid cysts are rarely seen in visceral organs, this case is the seventh case of cecum-originated epidermoid cyst that has been reported in the literature. The histogenesis of epidermoid cyst is unknown. These cysts are generally accepted to be sequestration cysts that may be either congenital or acquired. Acquired epidermoid cysts are believed to be traumatic or iatrogenic. The cesarean delivery may have been a cause of this condition in the present case. On ultrasonographic examination, these cysts can be misdiagnosed as ovarian cysts.  相似文献
