C. PATHOLOGICAL FINDINGS IN THE CENTRAL NERVOUS SYSTEM OF AIDS PATIENTS ON ANTIRETROVIRAL THERAPУ:

RETROSPECTIVE STUDY OF 1597 AUTOPSIES

Vago, Luca; Bonetto, Sara; Nebuloni, Manuela et al

AIDS, Vol. 6, Issue 14, 2002, pp. 1925-1928

OBJECTIVE To evaluate the prevalence of HIV-related central nervous system (CNS) lesions (HIV-encephalitis and/or HIV-leukoencephalopathy: HIV-E/L) with and without concomitant opportunistic diseases in a large autopsy series, and to correlate it with the changes in antiretroviral treatment.

METHODS We reviewed 1597 autopsies of HIV-positive patients performed between 1984 and 2000, and divided into four time periods on the basis of the therapeutic regimens: 1984-1987, no therapy; 1988-1994, monotherapy (zidovudine); 1995-1996, dual combination therapy with nucleoside reverse transcriptase inhibitors (NRTI); and 1997-2000, triple combination therapy including two NRTI and at least one protease inhibitor or non-NRTI.

RESULTS The CNS of 1210 patients (76%) was affected by opportunistic diseases, HIV-related lesions or both. The prevalence of HIV-related lesions in the four periods was respectively 54%, 32%, 18% and 15%. During the last period, however, differences in HIV-E/L between treated and untreated patients were not statistically significant.

CONCLUSIONS These neuropathological data confirm the efficacy of antiretroviral treatment in reducing the frequency of HIV-related CNS lesions in AIDS patients.

D. TREATMENT OF TRAUMATIC BRAIN INJURY WITH MODERATE

HYPOTHERMIA

Donald W. Marion, M.D., Louis E. Penrod, M.D., Sheryl F. Kelsey, Ph.D. et al

New England Journal of Medicine, 1997

BACKGROUND Traumatic brain injury causes several metabolic processes that can exacerbate the injury.

OBJECTIVE To determine whether hypothermia may limit some of these harmful metabolic responses.

METHODS In a randomized, controlled trial, we compared the effects of moderate hypothermia and normothermia in 82 patients with severe closed head injuries (a score of 3 to 7 on the Glasgow Coma Scale). The patients assigned to hypothermia were cooled to 33°C a mean of 10 hours after injury, kept at 32 to 33°C for 24 hours, and then rewarmed. A specialist in physical medicine and rehabilitation evaluated the patients 3, 6, and 12 months later with the use of the Glasgow Outcome Scale.

RESULTS At 12 months, 62 percent of the patients in the hypothermia group and 38 percent of those in the normothermia group had good outcomes (moderate, mild, or no disabilities). Hypothermia did not improve the outcomes in the patients with coma scores of 3 or 4 on admission. Among the patients with scores of 5 to 7, hypothermia was associated with significantly improved outcomes at 3 and 6 months, although not at 12 months.

CONCLUSIONS Treatment with moderate hypothermia for 24 hours in patients with severe traumatic brain injury and coma scores of 5 to 7 on admission hastened neurologic recovery and may have improved the outcome.

А. YOGURT WITH ACTIVE BACTERIAL CULTURES IS THE ORIGINAL

HEALTH FOOD

K. Arunachalam, H. S. Gill, R. K. Chandra

European Journal of Clinical Nutrition, 2000. Volume 54, No. 3, pp. 263-267

BACKGROUND. Yogurt provides beneficial cultures that aid in digestion and provides an excellent source of calcium. Yogurt may, in fact, be the ultimate health food by enhancing the immune response in those who eat it regularly. A recent review of the researches on the immunological effects of yogurt with active cultures showed that many of the studies produce compelling evidence that yogurt improves resistance to immune related disease.

AIM We investigated whether active yogurt bacteria significantly improve human immunity.

METHOD The present study followed 25 healthy, elderly human volunteers in a randomized, double blind, placebo-controlled study. Volunteers were given either milk or milk with active yogurt bacteria (Bifidobacterium lactis) for six weeks.

RESULTS. Immune response variables were then measured and the subjects who consumed the yogurt bacteria benefited by a significantly enhanced immune response as compared to controls.

56

CONCLUSION Based on the findings we concluded that these considerable improvements are likely to provide significant health benefits to those who eat yogurt with active cultures regularly.

Bifidobacterium lactis – бифидобактерии лактис

D. R . Gustafson, E. A. Vetter, D. R. Larson

Clinic Proceedings, 2000, Vol. 75, No. 7, pp. 705-708

OBJECTIVE To evaluate the effects of 4 different drying methods to remove bacteria from washed hands.

SUBJECTS AND METHODS One hundred adult volunteers participated in this randomized prospective study. All bacterial counts were determined using a modified glove-juice sampling procedure. The difference was determined between the amounts of bacteria on hands artificially contaminated with the bacterium Micrococcus luteus before washing with a nonantibacterial soap and after drying by 4 different methods (cloth towels, paper towels, warm forced air from a mechanical hand-activated dryer, and spontaneous room air evaporation). The results were analyzed using a nonparametric analysis (the Friedman test). By this method, changes in bacterial colony-forming unit values for each drying method were ranked for each subject.

RESULTS The results for 99 subjects were evaluable. No statistically significant differences were noted in the numbers of colony-forming units for each drying method.

CONCLUSION These data demonstrate no statistically significant differences in the efficiency of 4 different hand-drying methods for removing bacteria from washed hands.

drying – сушка

nonantibacterial soap – небактерицидное мыло

C. ARE WE AWARE HOW CONTAMINATED OUR MOBILE PHONES

WITH NOSOCOMIAL PATHOGENS ARE?

Fatma Ulger, Saban Esen, Ahmet Dilek, Keramettin Yanik et al

Annals of Clinical Microbiology and Antimicrobials, 2009, Vol. 8, No. 7

BACKGROUND The objective of this study was to determine the contamination rate of the healthcare workers' (HCWs') mobile phones and hands in operating room. Microorganisms from HCWs' hands could be transferred to the surfaces of the mobile phones during their use.

METHODS 200 HCWs were screened; samples from the hands of 200 participants and 200 mobile phones were cultured.

RESULTS In total, 94.5% of phones demonstrated evidence of bacterial contamination with different types of bacteria. The gram negative strains were isolated from mobile phones of 31.3% and the ceftazidime resistant strains from the hands were 39.5%. S. aureus strains isolated from mobile phones of 52% and those strains isolated from hands of 37.7% were methicillin resistant. Distributions of the isolated microorganisms from mobile phones were similar to hands isolates. Some mobile phones were contaminated with nosocomial important pathogens.

CONCLUSION These results showed that HCWs' hands and their mobile phones were contaminated with various types of microorganisms. Mobile phones used by HCWs in daily practice may be a source of nosocomial infections in hospitals.

D. EFFECTS OF BACTEREMIA AND HIV SEROPOSITIVITY ON

RADIOGRAPHIC APPEARANCE

Rosita M. Shah

American Journal of Roentgenology, 2000

OBJECTIVE Our purpose was to establish the incidence of lobar versus bronchopneumonia patterns in patients hospitalized for pneumococcal pneumonia and to determine whether bacteremia or HIV status affects the radiographic appearance.

MATERIALS AND METHODS 81 patients with community-acquired pneumococcal pneumonia and positive findings on admission chest radiographs wereselected from a group of 105 patients with positive findings for Streptococcus pneumoniae from sputum or blood cultures. Patients less than 16 years old and those with nosocomial pneumonia, aspiration pneumonia, or coexistent lung disease were excluded.

58

RESULTS 59 (73%) of the 81 patients were bacteremic and 20 (25%) of the 81 patients were HIV-positive, including14 patients (17%) who were both bacteremic and HIV-positive. Focal lobar consolidation was the most common pattern, observed in 48% patients. Multifocal lobar consolidation was the next most frequent pattern, occurring in 33%. Multifocal and focal bronchopneumonia patterns were seen in 16% and 2% of the patients, respectively. CONCLUSION Lobar consolidation, involving single or multiple lobes, is the most common radiographic pattern of community-acquiredpneumococcal pneumonia.The pattern of consolidation is not influenced by bacteremiaor HIV status.
