Borderline CD30+ Cutaneous Lymphoproliferative Disorder: Report of a Case with Expression of Cytotoxic Markers and Response to Clarithromycin

CD30+ cutaneous lymphoproliferative disorders (CLPDs) are usually characterized by a benign clinical course. The prognostic value of cytotoxic markers in these lymphomas has not been evaluated in large series. We describe a case of borderline CD30+ CLPD with cytotoxic phenotype, presenting in a 22-year-old male patient as an ulcer on the forearm. He reported having had similar ulcers on the buttock and thigh that spontaneously regressed over the course of 1 year. The lesion resolved with a single course of clarithromycin; a subsequent lesion, too, responded to clarithromycin, and no recurrences or systemic involvement have been documented in the 9-month follow-up. A conservative approach in the management of CD30+ CLPD is recommended. We believe that the anti-inflammatory and apoptotic effects of clarithromycin on T cells may have hastened the remission process.

Case Report of Malignant Endometrial Polyps

The aims of this retrospective review were to determine the frequency of malignant endometrial polyps diagnosed with ambulatory hysteroscopy in the Obstetrics/Gynaecology Department of HDE, Lisbon, between January 2001 and December 2005 and to characterize these cases according to risk factors, sonographic and endoscopic findings tumoral histology, and tumor stage.We found seven cases of malignant endometrial polyps in a total of 1333 polyps initially diagnosed: an incidence rate of 0. 53%. These seven patients had a mean age of 68 years (55–82 years), and all were postmenopausal, with five having one risk factor each for endometrial cancer. Metrorrhagia was present in six of the seven patients(85.7%). Ultrasonography was abnormal in all seven patients, with a mean endometrial thickness of 26 mm(range: 12–44 mm). The hysteroscopy images suggested malignancy in all cases. All except one patient had a single polyp. The polyps had volumes between 1.5 and 3 cm; two were removed completely and five were biopsed. The histological subtype was: mixed endometrioid/serous papillary or clear cell (2), adenocarcinoma with squamous differentiation (2), carcinosarcoma (2), and clear cell carcinoma (1). Malignancy inside polyps is rare, but diagnostic hysteroscopy with visual guided biopsies can identify these cases in the earlier stages. The risk factors are not different from those of other endometrial carcinomas, but the histological subtype seems to point to more aggressive cancers.

Psychiatric and Psychosocial Predictors of Medical Outcome After Liver Transplantation: a Prospective, Single-Center Study

OBJECTIVE: Recognizing the potential impact of psychiatric and psychosocial factors on liver transplant patient outcomes is essential to apply special follow-up for more vulnerable patients. The aim of this article was to investigate the psychiatric and psychosocial factors predicted medical outcomes of liver transplanted patients. METHODS: We studied 150 consecutive transplant candidates, attending our outpatient transplantation clinic, including 84 who had been grafted 11 of whom died and 3 retransplanted. RESULTS: We observed that active coping was an important predictor of length of stay after liver transplantation. Neuroticism and social support were important predictors of mortality after liver transplantation. CONCLUSION: It may be useful to identify patients with low scores for active coping and for social support and high scores for neuroticism to design special modes of follow-up to improve their medical outcomes.

Infections After Liver Transplantation: A Retrospective, Single-Center Study

Objective. To access the incidence of infectious problems after liver transplantation (LT). Design. A retrospective, single-center study. Materials and Methods. Patients undergoing LT from January 2008 to December 2011 were considered. Exclusion criterion was death occurring in the first 48 hours after LT. We determined the site of infection and the bacterial isolates and collected and compared recipient’s variables, graft variables, surgical data, post-LT clinical data. Results. Of the 492 patients who underwent LT and the 463 considered for this study, 190 (Group 1, 41%) developed at least 1 infection, with 298 infections detected. Of these, 189 microorganisms were isolated, 81 (51%) gram-positive bacteria (most frequently Staphylococcus spp). Biliary infections were more frequent (mean time of 160.4 167.7 days after LT); from 3 months after LT, gram-negative bacteria were observed (57%). Patients with infections after LT presented lower aminotransferase levels, but higher requirements in blood transfusions, intraoperative vasopressors, hemodialysis, and hospital stay. Operative and cold ischemia times were similar. Conclusion. We found a 41% incidence of all infections in a 2-year follow-up after LT. Gram-positive bacteria were more frequent isolated; however, negative bacteria were commonly isolated later. Clinical data after LT were more relevant for the development of infections. Donors’ variables should be considered in future analyses.
