1/10. Contribution of magnetic resonance imaging for the diagnosis of median nerve lesion after endoscopic carpal tunnel release.Deterioration of pre-existing signs or appearance of a nerve deficit raise difficult problems during the complicated course following endoscopic carpal tunnel release. One possible explanation is transient aggravation of nerve compression by passage of the endoscopy material, but these signs may also be due to incomplete section of the flexor retinaculum or an iatrogenic nerve lesion. Each case raises the problem of surgical revision. The authors report three cases of open revision in which MRI allowed a very precise preoperative diagnosis of the lesions and all of the MR findings were confirmed during surgical revision. In the first case, MRI showed section of the most radial branches of the median nerve (collateral nerves of the thumb, index finger and radial collateral nerve of the middle finger). The proximal origin of the nerve of the 3rd web space, above the retinaculum, an anatomical variant, was also identified. Section of 2/3 of the nerve of the 3rd web space, proximal to the superficial palmar arch, was observed in the second case. Simple thickening of the nerve of the 3rd web space, without disruption after opening of the perineurium, was observed in the third case. MRI therefore appears to be an examination allowing early and precise definition of indications for surgical revision in this new iatrogenic disease.- - - - - - - - - - ranking = 1keywords = iatrogenic disease (Clic here for more details about this article) |
2/10. starch granuloma syndrome. starch peritonitis as an iatrogenic disease.A report of a patient with granulomatous peritonitis following general surgery is presented. laparoscopy was performed as the final diagnostic procedure. Prevention is the remedy for this iatrogenic problem.- - - - - - - - - - ranking = 4keywords = iatrogenic disease (Clic here for more details about this article) |
3/10. Foreign body gingivitis: an iatrogenic disease?Gingival biopsy specimens from eight patients exhibiting a localized, erythematous, or mixed erythematous/leukoplakic gingivitis that was refractory to conventional periodontal therapy were examined histologically and by energy-dispersive X-ray microanalysis. Histologic examination revealed variable numbers of small, usually subtle, sometimes equivocal, and occasionally obvious foci of granulomatous inflammation. Special stains for fungi and acid-fast bacilli were consistently negative. In all cases, the granulomatous foci contained particles of foreign material that were often inconspicuous and easily overlooked during routine histologic examination. Energy-dispersive X-ray microanalysis of these foreign particles disclosed Ca, Al, Si, Ti, and P in most lesions. However, other elements such as Zr, V, Ag, and Ni were found only in specific biopsy specimens. By comparing the elemental analyses, clinical features, and history of the lesions, strong evidence for an iatrogenic source of the foreign material was found in one case, and good evidence in five cases. In the remaining two patients, the source of the foreign particles remains unresolved.- - - - - - - - - - ranking = 4keywords = iatrogenic disease (Clic here for more details about this article) |
4/10. iatrogenic disease and the primary care physician.Primary care physicians need to be aware of iatrogenic disease and its causes. Adverse drug reactions, including drug-drug interactions, and certain diagnostic procedures may lead to iatrogenic complications. Hospitalized patients, especially the elderly, face increased risks of such complications. physicians who are aware of common adverse reactions to drugs, drug combinations, and medical procedures may be able to help patients avoid unnecessary distress and morbidity.- - - - - - - - - - ranking = 1keywords = iatrogenic disease (Clic here for more details about this article) |
5/10. Myospherulosis of the mastoid antrum: a case report.Myospherulosis is a recently discovered iatrogenic disease caused by the implantation during surgery of mineral oil- or petrolatum-based products into various tissues. The condition results from the action of lipid substances on extravasated erythrocytes. The case report presented is the first detailed description of this uncommon, unique inflammatory lesion occurring in the mastoid and is the second otitic case reported in the literature. The lesion mimicked recurrent cholesteatoma 6 years following an intact canal wall mastoidectomy. As in myospherulosis of the paranasal sinuses, the symptoms and findings of otitic myospherulosis are those of the preceding disease.- - - - - - - - - - ranking = 1keywords = iatrogenic disease (Clic here for more details about this article) |
6/10. Cervical esophageal perforation diagnosed by endoscopy in a premature infant: review of recent literature.A case of cervical esophageal perforation in a premature infant by an orogastric polyvinyl chloride (PVC) tube is reported. Perforation appeared as an esophageal atresia, suspected because of the inability to aspirate gastric secretions. Initially, atresia was confirmed by an esophagogram, but endoscopy revealed a "double esophagus" with a normally located and developed esophagus and a blind mediastinal fistula starting at the opposite side of the glottis. The "double esophagus" was confirmed by an esophagogram, followed by a contrast study in the pharynx. esophageal perforation in the neonate is an iatrogenic disease that may mimic esophageal atresia. We recommend endoscopy instead of contrast studies for suspected esophageal atresia.- - - - - - - - - - ranking = 1keywords = iatrogenic disease (Clic here for more details about this article) |
7/10. Intracerebral calcifications in childhood lymphoblastic leukemia. A new iatrogenic disease?A 3-year-old child diagnosed as having acute lymphatic leukemia (ALL), developed meningeal leukemia 36 months after the onset of the disease. He was twice subjected to cranial irradiation plus intrathecal methotrexate (i.t. MTX). skull radiology showed bilateral gyriform calcification of both cerebral hemispheres. Hematological relapse was first detected 5 years after diagnosis and the child died 5 months later. The most striking findings of a right frontal lobe biopsy and the postmortem examination were wide calcium deposits located in the cortex and in the adjacent white matter. Intense demyelination as well as areas of neuron poverty were apparent in the necropsy but in the biopsy specimen. The possible interrelationship between such deposition and cranial irradiation and/or i.t. MTX suggests a new iatrogenic disorder.- - - - - - - - - - ranking = 4keywords = iatrogenic disease (Clic here for more details about this article) |
8/10. Acquired lobar emphysema in premature infants with bronchopulmonary dysplasia: an iatrogenic disease?Five premature infants in whom bronchopulmonary dysplasia developed following prolonged neonatal respiratory support are presented. In all five patients, right middle and/or lower lobe emphysema related to focal obstructing endobronchial masses of granulation tissue subsequently developed. It is speculated that the granulation tissue formed in response to the repeated mechanical trauma of endotracheal tube suctioning.- - - - - - - - - - ranking = 4keywords = iatrogenic disease (Clic here for more details about this article) |
9/10. Management of hyperstimulation syndrome.A case of hyperstimulation syndrome secondary to Pergonal therapy is presented. Successful management was based principally on severe sodium and fluid restriction without the use of volume expanders. The rationale for this therapeutic approach is presented and discussed. Although this iatrogenic disease should be virtually eliminated with the monitoring of daily urinary estrogens, severe hyperstimulation may still occur as a result of laboratory error.- - - - - - - - - - ranking = 1keywords = iatrogenic disease (Clic here for more details about this article) |
10/10. methyldopa hepatitis. A report of six cases and review of the literature.Six cases of methyldopa hepatitis, including two in which the patients died are reported; and 77 cases from the literature are reviewed. patients in whom severe hepatotoxic reactions to methyldopa develop usually complain of prodromal symptoms typical of hepatitis, often with fever, one to four weeks after therapy is initiated. jaundice, when it occurs, is usually manifest within three months. Asymptomatic, transient elevations of serum transaminase levels may occur in patients receiving methyldopa. However, since the clinical and histologic features of hepatic injury from methyldopa are indistinguishable from viral hepatitis, it is suggested that the incidence of this iatrogenic disease is higher than generally appreciated. serum transaminase levels should be determined at the initiation of therapy with methyldopa and four weeks later. Moreover, any patient who has unexplained fever or the prodromal symptoms of hepatitis should undergo liver chemistry studies immediately.- - - - - - - - - - ranking = 1keywords = iatrogenic disease (Clic here for more details about this article) |
