Internal Hernias: Clinical Findings,Management, and Outcomes in 49 Nonbariatric Cases 总被引:1,自引:0,他引:1

Internal hernia, the protrusion of a viscus through a peritoneal or mesenteric aperture, is a rare cause of small bowel obstruction.
We report the clinical presentation, surgical management, and outcomes of one of the largest series of nonbariatric internal
hernias. Ten-year retrospective review of patients at our institution yielded 49 cases of internal hernias. Majority of patients
presented with symptoms of acute (75%) or intermittent (22%) small bowel obstruction. While 16% of CT scans were suspicious
for internal hernia, in no cases the preoperative diagnosis of internal hernia was made. The most frequent internal hernias
were transmesenteric (57.0%) and 34 hernias (69%) were caused by previous surgery. All internal hernias were reduced and the
defects were repaired. Compromised bowel was present in 22 cases and 11 patients underwent small bowel resection. The mean
postoperative hospitalization was 10.9 days. The overall mortality rate from our series is 2%, and the morbidity rate is 12%.
Transmesenteric hernias, as complications of previous surgeries, are the most prevalent internal hernias. Preoperative diagnosis
of internal hernia is extremely difficult because of the nonspecific clinical presentation. However, if discovered promptly,
internal hernias can be repaired with acceptable morbidity and mortality.

Localization of a gene for otosclerosis to chromosome 15q25-q26 总被引:5,自引:0,他引:5
Tomek MS; Brown MR; Mani SR; Ramesh A; Srisailapathy CR; Coucke P; Zbar RI; Bell AM; McGuirt WT; Fukushima K; Willems PJ; Van Camp G; Smith RJ 《Human molecular genetics》1998,7(2):285-290
Among white adults otosclerosis is the single most common cause of hearing
impairment. Although the genetics of this disease are controversial, the
majority of studies indicate autosomal dominant inheritance with reduced
penetrance. We studied a large multi- generational family in which
otosclerosis has been inherited in an autosomal dominant pattern. Five of16
affected persons have surgically confirmed otosclerosis; the remaining nine
have a conductive hearing loss but have not undergone corrective surgery.
To locate the disease- causing gene we completed genetic linkage analysis
using short tandem repeat polymorphisms (STRPs) distributed over the entire
genome. Multipoint linkage analysis showed that only one genomic region, on
chromosome 15q, generated a lod score >2.0. Additional STRPs were typed
in this area, resulting in a lod score of 3.4. STRPs FES (centromeric) and
D15S657 (telomeric) flank the 14. 5 cM region that contains an otosclerosis
gene.

Summary The authors report the results of 115 dissections of the base of the distal phalanx of fingers and toes. In 85% of cases including hypoplastic supernumerary digits, there is a connective ligament-like structure. It is a dorsal expansion of the lateral ligament of the distal inter-phalangeal joint arising from the intermediate phalanx and ending in the matrix and the lunula. This ligament may have a role in biomechanical strains on the nail. It can explain some dystrophic nails associated with some malpositioned joints in fingers or toes.
Structure ligamentaire de la base de l'ongle
Résumé Les auteurs rapportent les résultats de 115 dissections portant sur la base de la phalange distale des doigts ou des orteils. Ils retrouvent dans 85 % des cas, y compris sur des doigts hypoplasiques surnuméraires, une formation conjonctive de type ligamentaire. Il s'agit d'une expansion dorsale du ligament latéral de l'articulation interphalangienne distale, naissant de l'extrémité distale de la phalange intermédiaire et se terminant au sein de la matrice et sur la lunule. Ce ligament ostéomatriciel peut jouer un rôle dans la transmission des contraintes biomécaniques sur l'ongle et expliquer les dystrophies unguéales stéréotypées associées à certaines malpositions articulaires des doigts ou des orteils.相似文献
