Dynamic of oxidative and nitrosative stress markers during the convalescent period of stroke patients undergoing rehabilitation.

BACKGROUND: Stroke patients have a redox imbalance, a consequence of both the cerebrovascular event and the associated pathological conditions. Our study was aimed to investigate the dynamic of some oxidative and nitrosative markers during the convalescent phase of postacute stroke patients undergoing rehabilitation. METHODS: We assessed thiol, advanced oxidation protein product, protein carbonyl, 3-nitro-l-tyrosine, ceruloplasmin and oxidized LDL concentrations, as well as gamma-glutamyltranspeptidase (GGT) activity in 20 patients at the beginning of the hospitalization and at the discharge moment, respectively, and 24 apparently healthy controls. RESULTS: We found significantly increased values for GGT (P = 0.04), ceruloplasmin (P = 0.01) and protein carbonyl (P = 0.04) in stroke patients at the hospitalization moment when compared with healthy controls, while total thiols were significantly decreased (P = 0.002). Rehabilitation was associated with a significant decrease of protein carbonyl (P = 0.03) and oxidized LDL particle concentrations (P = 0.03), as well as GGT activity (P = 0.02). At the hospitalization moment, both GGT and ceruloplasmin were significantly negatively correlated with non-proteic thiols (r = -0.44, P = 0.049, and r = -0.53, P = 0.015, respectively) and significantly positively with protein carbonyls (r = +0.80, P < 0.001, and r = +0.69, P < 0.001, respectively) suggesting putative roles of GGT and ceruloplasmin in the redox imbalance. CONCLUSIONS: These results highlight the existence of a redox imbalance in postacute stroke patients, and the possible benefits of an antioxidant-based therapy for the recovery of these patients.

Systematic microbiological tests in kidney transplantation and their value in predicting posttransplantation infection.

BACKGROUND: Immunosuppressive therapy has many side effects among which is an increased infectious risk for the recipient. Transmission of pathogens from the graft to the recipient has not been well evaluated; there are no guidelines regarding the need for microbiological tests on the graft prior to transplantation. We routinely performed such tests to evaluate the risk and determine whether a patient should receive preemptive antibiotic therapy after transplantation. We herein have reported our preliminary results. MATERIALS AND METHODS: We reviewed 150 consecutive renal transplantations from cadaveric heart-beating donors. Microbiological tests were systematically performed not only on the preservation solution, but also on graft artery, vein, ureter, and perirenal fat. We reviewed the recipient's medical history for clinically significant infectious episodes in the first month after transplantation. RESULTS: Thirty-one percent of all microbiological tests were positive with 23 patients showing multiple positive tests, 74% of which were concordant. We documented 3 cases of direct graft-to-recipient pathogen transmission, all of which presented with 3 positive concordant tests. Graft culture prior to transplantation is often positive, but in more than half of the cases positive tests are either isolated or discordant. We only treated patients with concordant test results; no adverse consequence was observed among the untreated patients. Transmission occurred only in patients with at least 3 concordant tests. CONCLUSIONS: Multiple microbiological tests on the graft prior to transplantation seemed useful to determine which patients would benefit from preemptive antibiotic therapy. Further studies may help to define which microbiological tests are the most important.

[Laparoscopic splenectomy for epithelial cyst of the spleen]. / Splenectomia laparoscopica in tratamentul chistului splenic epitelial. Caz clinic.

Splenic cysts of all types are a relatively rare entity. The origin of epithelial cysts of the spleen is controversial, most probably congenital in origin. Generally, epithelial cysts of the spleen are asymptomatic and discovered incidentally. We present the case of a 40-year-old woman with a 3.5 cm splenic cyst diagnosed four years before. The cyst raised progressively in dimension, the actual size being of 6.5 cm. Computed tomography scan and magnetic resonance showed a central splenic cyst in close relations with main splenic vessels. An initial indication of partial splenectomy was established, eventually a total splenectomy being performed by laparoscopy due to close relations of the cyst with the main hilar splenic vessels. The hemostasis was assured with the aid of Ligasure Atlas 10 mm instrument. The pathology examination revealed a multilocular splenic cyst with a cuboidal epithelial lining. Central localization of splenic cysts represents an indication for total splenectomy. Laparoscopy provides a minimal access method of obtaining pathological confirmation of diagnosis, reduction of cyst complications, and a short hospital stay. This article discusses different aspects of epithelial cysts related to pathology, diagnostic and indications for operative treatment, a review of the literature being also presented.

[Liver transplantation--considerations over 8 cases operated in the year 2000]. / Transplantul hepatic--consideratii asupra a 8 cazuri operate în anul 2000.

In the year 2000, at the Department for General Surgery and Liver Transplantation from The Fundeni Clinical Institute Bucharest, seven OLTs and one living-related transplantation were performed in 6 adults and 2 children. Postoperative complications were: bile leakage, hemoperitoneum, lower gastrointestinal hemorrhage, parietoabdominal hematoma. There was only one postoperative death due to septic complications in the 18th p.o.d. and one late death due to pneumonia of unknown origin. After the results in the year 2000 there was an increased number of donors and referrals. We consider that now in Romania this is an established program that will continue depending on the number of donors and financing.

[The clinico-statistical correlations of eye injuries in children]. / Corelatii clinico-statistice privind traumatismele oculare la copii.

This is a study of epidemiological and medico-social aspects of eye injuries in children. It refers to 624 cases, over the period 1996-1999; only 108 of them needed admission. The analysed factors are: the alleged person, the traumatic agent, the socio-climatic environment and the medical aspects of the accident. Only mechanical traumas are considered. The study reveals the quantitative indicators of various aspects such as: medical attendance, surgery, drug treatment, decreases of vision.
