The histopathological changes observed in the cutaneous rash of three patients who suffered the acute phase of HFV infection are described. In all three patients a perivascular and interstitial inflammatory infiltrate was present in the upper and mid-reticular dermis. In one biopsy isolated areas of epidermal necrosis were observed and in the two other biopsies a perifollicular inflammatory infiltrate was detected with perforation in one case. Furthermore, a periductal infiltrate was observed in one of these biopsies. 相似文献

Purpose
To analyse the short-term outcome in patients with Listeria monocytogenes meningoencephalitis (LMME) to improve management and outcome.Methods
Observational study with adult patients with LMME between 1977 and 2009 at a tertiary hospital in Barcelona, Spain. Parameters that predicted outcome were assessed with univariate and logistic regression analysis.Results
Of 59 cases of LMME, 28 occurred in the last decade. Since 1987, a new protocol has been used and 29/45 patients (64 %) treated since then received adjuvant dexamethasone. In patients who received this treatment there was a trend towards fewer neurological sequelae (5 vs 33 %; p = 0.052). Antiseizure prophylaxis with phenytoin was administered in 13/45 (28 %) patients. Seizures occurred in 7/45 (16 %) patients, all in the group who did not receive phenytoin. Hydrocephalus presented in 8/59 (14 %). It was never present at admission and five patients needed neurosurgical procedures. Sequelae after 3 months were present in 8/45 (18 %), mostly cranial nerve palsy. Rhombencephalitis (RE) was related to the presence of neurologic sequelae (OR: 20.4, 95 % CI: 1.76–236). Overall mortality was 14/59 (24 %), 9/59 (15 %) due to neurological causes related to hydrocephalus or seizures. Mortality was defined as early in 36 % and late in 64 %. In the multivariate analysis, independent risk factors for mortality were presence of hydrocephalus (OR: 17.8, 95 % CI: 2.753–114) and inappropriate empirical antibiotic therapy (OR: 6.5, 95 % CI: 1.201–35).Conclusions
Outcome of LMME may be improved by appropriate empirical antibiotic therapy, suspicion and careful management of hydrocephalus. Use of adjuvant dexamethasone or phenytoin in a subgroup of these patients might have a benefit. 相似文献5.

Radioimmunoscintigraphy (RIS) with BW 431/26 monoclonal antibody (MoAb) labelled with 99Tcm (962 MBq) has been performed in 64 patients with colorectal carcinoma, one of them with two independent tumours. The group consisted of 46 primary lesions, 15 pelvic recurrences and four suspected recurrences which were shown to be liver metastases. Imaging of liver was obtained in all patients, but surgical liver examination was performed in only 56 of them. Planar scans were obtained at 4 and 24 h postinjection. Tomographic images were also performed in five patients. The final diagnosis was confirmed in all patients by their clinical course and by findings at surgery and pathology. A comparative study between the RIS results and the final diagnosis gave a global sensitivity in primary tumours and pelvic recurrences of 59.7% with an accuracy of 59.0%. When rectal tumours were excluded, the results were 81.1 and 84.9%, respectively. In liver metastases the sensitivity was 50%, with an accuracy of 85.7% and a specificity of 100%. No correlation has been found between CEA serum levels and lesion detection. In conclusion, RIS is a useful technique for the study and localization of colorectal tumours, being also indicated in patients with normal carcinoembryonic antigen (CEA) serum levels and clinical suspicion of illness. 相似文献

In a series of 110 liveborn infants who died within 24 h of birth, and six 14- to 17-week-old fetuses, the development of perirenal brown fat was studied by morphometric and biomathematical methods. Brown fat was present at the 20th week of age and, taking as index of maturity the population of multilocular adipocytes, its development progressed according to a 3-parametric logistic growth function, with a half-time of 26 weeks and a tendency to asymptotic stabilization by the 35th week. Unilocular adipocytes appeared early and their low percentage (10.9%) remained relatively stable. Brown fat development in 75% of the cases of small-for-dates corresponded to that of infants with matched postconceptional age but appropriate birth weight. Abnormal cases presented whether a persistence of immature patterns or an unusual predominance of unilocular cells. No changes due to lipolysis were detected in any case. 相似文献

Cystic lesions occurring on the ventral surface of the penis have been classified as median raphe cysts of the penis. They are lined by pseudostratified, columnar or stratified squamous cell epithelium, mimicking the epithelial lining of the male urethra. Ciliated cysts of the human skin are unusual. Cystic lesions containing ciliated cells have been noted to occur in the chest, neck, or head, and bronchogenic origin has been the most accepted explanation for its origin. Other reports show the presence of ciliated cysts on the lower extremities, and the mechanism of formation is still a debated question. A case of median raphe cyst of the penis containing ciliated epithelium is presented. The existing literature about these cutaneous lesions is reviewed, including the possible mechanisms believed to be involved in its origin. 相似文献
