Effect of major burns on early and late activating markers of peripheral blood T lymphocytes.

It is known that lymphocytes immunophenotype is a reflection of the functional level of the immune system. The immunosuppressive effect of major burns is also known for many years. T lymphocytes of 50 major burn patients were analyzed in base line (BL) samples at 24 hours and at 1 week and 2 weeks after burn, using monoclonal antibodies of CD3, CD4, CD8, CD25 (IL2R) and HLA-DR by flow cytometry and ß2-microglobulin (ß2-m) by ELISA. Recorded values were compared with those of 50 healthy donors. There was statistically significant reduction in absolute number of CD3 positive cells (CD3+) (p<0.000) and CD4/CD8 ratio (p=0.01) in the first 24 hours in comparison with controls. CD25 (IL-2R) shows insignificant upregulation on T lymphocytes after burn with significant upregulation of HLA-DR. The absolute number of CD3+ cells began to increase after 2 weeks (p=0.03) but remained less than controls (p=0.08). CD4/CD8 ratio was more or less same as healthy controls after 2 weeks. Upregulation of CD25 was insignificantly increased and that of HLA-DR was markedly increased after 2 weeks (p=0.001). Significant negative correlations were detected between mean values of ß2-m and both absolute numbers of CD3 and CD4 positive cells in BL and one week samples. In addition there was significant correlation between mean values of ß2-m and values of CD25 expression in the BL samples. The obtained data is suggestive of persistent activation of T lymphocytes two weeks after major burns whereas early shedding of ß2-m is related to activation of lymphocytes increasing their susceptibility to apoptosis, both indicative of altered immune response. Burn intensivists and surgeons should be keen to support the patients' immune system in the first hours following major burns. This support will ensure free-bacteremic blood with a consequent better prognosis.

[Prevalence of nosocomial infections in 27 hospitals in the Mediterranean region]. / Prévalence des infections nosocomiales dans 27 hôpitaux de la région Méditerranéenne.

A multicentre study was conducted in 27 hospitals in Algeria, Egypt, Italy, Morocco and Tunisia to evaluate the prevalence and characteristics of the nosocomial infections. The study population (4634 patients) was relatively young, mean age 41.1 (standard deviation 23.4) years. The prevalence of nosocomial infections was 10.5%; this was higher in non-teaching centres and moderate-sized hospitals. Overall, urinary tract infections were the most common. Paediatric departments rated particularly high (11.3%). The most commonly isolated organisms were: Escherichia coli (17.2%), Staphylococcus aureus (12.5%), Pseudomonas aeruginosa and Klebsiella pneumoniae (9.2% each). On the day of the study, 40.7% of the patients were under treatment with antibiotics, with nearly half for an empirical indication. Nosocomial infection was significantly associated with mechanical ventilation, hospitalization > or = 8 days, presence of a central or peripheral catheter), urinary catheter, diabetes and age.

Prevalence of nosocomial infections in 27 hospitals in the Mediterranean region

A multicentre study was conducted in 27 hospitals in Algeria, Egypt, Italy, Morocco and Tunisia to evaluate the prevalence and characteristics of the nosocomial infections. The study population [4634 patients] was relatively young, mean age 41.1 [standard deviation 23.4] years. The prevalence of nosocomial infections was 10.5%; this was higher in non-teaching centres and moderate-sized hospitals. Overall, urinary tract infections were the most common. Paediatric departments rated particularly high [11.3%]. The most commonly isolated organisms were: Escherichia coli [17.2%], Staphylococcus aureus [12.5%], Pseudomonas aeruginosa and Klebsiella pneumoniae [9.2% each].

Multicentre study on hand hygiene facilities and practice in the Mediterranean area: results from the NosoMed Network.

Hand hygiene literature is scarce in the southern Mediterranean area. In order to establish a baseline position, a study was performed in four Mediterranean countries. Seventy-seven hospital wards in 22 hospitals were enrolled and information on hand hygiene practice and facilities were collected. The overall compliance rate was very low (27.6%), and was significantly higher where the perceived risk was considered to be high. Intensive care units showed the highest level of compliance. Analysis by country indicated higher compliance in Egypt (52.8%) and Tunisia (32.3%) compared with Algeria (18.6%) and Morocco (16.9%). Facilities for hand hygiene, particularly consumables, were shown to be deficient. Multi-approach programmes combining the production of official local recommendations, education and regular evaluation of hand hygiene practice are much needed to improve the present situation.

[Esthetic pinching of the globular nasal tip. Technical note]. / Pincement esthétique de la pointe nasale globuleuse. Note technique.

A conservative technique designed to simple reduce the width of nasal tip is presented. It consists of approximation of the anterosuperior segments of alar lateral crus after their elevation on median pedicles. A marginal inferior band of alar cartilage is left adherent to the nasal mucosa. The procedure is completed without cartilaginous excision. We tried this technique in ten rhinoplasties and the results were satisfactory. The nasal tip narrowing obtained has no significant effect on either tip projection and position or nostril shape.
