The study investigates retroreflective fabrics’ efficiency from the point of view of the interaction of their visibility, thermo-physiological comfort properties, and durability (represented by physical-mechanical performance). The effect of the combination of two production technologies (reflective transfer films and screen printing method) and two reflector covering sizes (25% and 85%) was examined. Technique for order of preference by similarity to ideal solution (TOPSIS) method was used to determine the best solution considering the abovementioned tested categories of properties. Retroreflective performance was in congruence with the used design coverage factor of the tested pattern. It was found that retroreflection of the tested pattern produced using screen printing technology was significantly lower than retroreflection of an identical pattern made by a transfer film. On the contrary, in terms of thermo-physiological comfort and physical-mechanical performance of the tested samples, screen printing technology shows significantly better results in almost all tested properties, especially in water vapor permeability, moisture management, and physical-mechanical performance. The solution for the abovementioned contradictory results can be achieved by using a combination of the advantages associated with each of these technology methods. Screen printing can be applied to specific regions of clothing that are exposed to extreme loading or sweating, and the transfer of film elements ensures high visibility with respect to the standards and biomotion principles that are deployed as prevalent benchmarks in the industry.

Objective: Neuropsychic manifestations of AIDS are still noticeable especially in developing countries. The aim of this short communication is to describe psychological, behavioral and neurologic disorders caused by either HIV-related disorders, or drug related toxicities in HIV-infected children from Cambodia (Phnom Penh, Sihanoukville) treated during 10 years with highly active antiretroviral therapy (HAART)., Methods: One hundred and thirty seven (137) HIV-positive children (age 2-19 years) treated with HAART since 2003 (6-10 years follow up) have been analyzed concerning opportunistic infections, other co-infections, renal parameters, hematologic parameters, chest X-ray, antiretroviral treatment, anti-tuberculotics and antibiotics treatment. We recorded prospectively all data since the start of HAART from 2003-2005 up to December 2012., Results: Occurrence of drug related neuritis due to stavudine (HAART) was less than 1% and was associated with anti-tuberculous agents accompanying HAART in HIV- and tuberculosis co-infected patients. Co-infections with neurotropic viruses were more frequent: 1 case of CMV retinitis, 18 cases of herpes zoster neuritis and 37 cases of generalized HZV infections (varicella), after onset HAART in children were recorded. All children responded well to anti-viral therapy with ganciclovir (CMV), vanciclovir or acyclovir (HZV) in combination with first line HAART., Conclusion: Neurologic disorders in children with HAART are less frequent than in adults. Anti-retrovirals and anti-tuberculosis drugs seem to be safe and less toxic in children then in adults. Co-infections with neurotropic viruses were more frequent, however, were successfully treated with anti-virals.

Community acquired bacterial (CBM) meningitis in diabetic patients was analyzed for risk factors and outcome in a cohort of 201 cases of meningitis within last 17 years: 15 patients with diabetes mellitus and meningitis were identified and compared for etiology and mortality as well as for neurologic sequellae with all CBM cases.

Within last 17 years we went through all charts of bacterial meningitis within our nationwide survey and among 372 cases we found 62 cases of MM, in 12 cases with meningococcal disease (with shock, petechial effusions or disseminated intravascular coagulation or digital gangrenes). MM was usually observed in young adults without any of investigated risk factors like neoplasia, ENT (ear, nose, throat) focuses, elderly age, sepsis, diabetes, alcoholism, trauma, neonatal VLBW etc. Trauma, diabetes mellitus, alcohol abuse and chronic sinusitis/otitis were significantly less frequently found as a risk factor for MM. Mortality was very low, only 4.8% and was lower than overall mortality in CBM (12.4%, NS). Also the proportion of neurologic sequellae (9.7%) and initial treatment failure (8.1%) were comparable or even lower. This positive outcome results are probably because all N. meningitis strains were susceptible to penicillin, chloramphenicol, cefotaxim, cotrimoxazol or ciprofloxacin. Other reason for low mortality was that most cases received oral antibiotic immediately, even before admission (50 of 62). 95.2% of cases survived, 90.3% without any transient neurological residual symptoms.

Review of 497 cases of neuroinfections in 7 tropical clinics in Ethiopia, Uganda, Burundi, Kenya, Sudan within 2000-2007 was performed. 97.5% of all cases was cerebral malaria (40.1%) and bacterial meningitis (56.4%). TB meningitis, cerebral cryptococcosis and sleeping sickness were very rare.
