We present a case of interhemispheric subdural hematoma in a patient aged 65 years. A day prior to admission he was struck with a water-pipe on the head. He went to sleep the same evening complaining of a slight headache. At about two o'clock in the morning the headache increased in intensity. By the morning he lost consciousness. On examination by a neurosurgeon the patient was found to be comatose. The physical examination revealed blue eyelids of the left eye, paraplegia of the right leg, paresis of the left leg and arms. Bilateral Babinski's reflex was present, the abdominal reflexes were absent, the tendon and periosteal reflexes were hyperactive. The pupils were equal in size and slowly reactive to light. The patient exhibited symptoms of meningoradicular irritation. An emergency CT scan revealed high-density area in the interhemispheric sulcus extending frontally to parietally. The patients was operated on in an emergency. At operation, extensive rupture of the sagittal sinus was identified. Later the patient died. The presented case was interesting with the extensive rupture of the sagittal sinus and the relatively long lucid interval until clear manifestation of the clinical picture becomes evident.

Due to the high number of immunosuppressed and other predisposed patients hospitals have to control and ensure the microbiological water quality. The origin for the occurrence of pathogenic microorganisms in water pipes is the formation of biofilm. Methods. For the permanent control of water safety a water safety plan (WSP) was realized as recommended by the WHO following the principle "search and destroy". The WSP is based on an established HACCP concept due to the special focus. The most important measures include the concept for sample taking depending on patient risk. 3 different categories) are distinguished: risk area1 (high infection risk), risk 2 (moderate infection risk), and risk area 3 (not increased infection risk). Additionally to the threshold value of the German law for the quality of drinking water (TrinkwV) three more limiting values were defined (warning, alert, and worst case) for immediate risk adapted reaction. Additional attention has to be focussed on lavatory sinks, which are an open bacterial reservoir. Therefore continuous disinfecting siphons were installed as part of the WSP in high risk areas. If extended technical equipment is not available, especially for immunocompromised patients the following measures are easy to realize: boiled (or sun exposed) water for nursing procedures as well alimentary use, no showering. Results. Comparing data over 3 years the microbial water quality was significantly improved resulting in no new case of nosocomial Legionella pneumoniae and decrease in neonatal sepsis. Conclusion. According to average situations with highly contaminated water system the management must be defined with implementation of water task force, immediate providing of special equipment, information of patients and staff and control of the water quality, an example for successful decontamination of the hospital within 24 hours is given.

The bacteria stained Gram-negative, are short rods, 1.5 Î¼m long and 0.5 Î¼m in diameter. The cells are usually single or in pairs. A very dense peptidoglycan layer was seen as well as cytoplasmic membrane and an outer membrane. The bacteria are nonmotile and do not form spores. They could grow at 42-73Â°C with optimum growth temperature of 65Â°C and optimum pH at 7.5. The bacteria were oxidase and catalase positive, sensitive to the antibiotics penicillin, erythromycin, tetracyclin, chloramphenicol and streptomycin but resistant to polymyxin B and rifampicin. The GC was about 64.5%. The isolates were compared to other known aerobic, heterotrophic bacteria and turned out to resemble to colourless Thermus strain X-1, which was also found to produce the brown pigment. The DNA:DNA similarity between the new isolates and Thermus X-1 was about 83%, whereas the similarity with Thermus aquaticus was about 46%. The new isolates together with strain X-1 are therefore considered to represent a new species, Thermus scotoductus.

The seasonal difference in potable water supply system had not yet been documented. Potable water samples from water supply systems of 16 localities were analyzed. The samples of running water, and tap swabs or tap scrapings were collected twice a year, in the spring and in the autumn. McNemar's test was used to analyze the difference of the occurrence of environmental mycobacteria between the vernal and the autumnal samples. A significant change in the presence of environmental mycobacteria in the potable water supply system was observed: the vernal samples yielded more positive results. This finding supports other observations of superficial water. We infer that this effect in potable water supply system may be caused by the change in temperature. Contamination rates were similar with no statistically significant difference between running water samples and that of swabs or scrapings. No time trend in the period 1984 - 1989 in the prevalence of myobacteria was detected. Direct microscopy showed massive colonisation with environmental mycobacteria of potable water supply system. Public health consequences of these findings should be further evaluated, as colonisation of water pipes can be associated with outbreaks of mycobacterial disease in immunocompromised patients. These has been also an increase in the incidence of mycobacterioses in North Moravian Region in recent years.

Collective and method: The lead contents of 235 permanent teeth extracted from 190 inhabitants of Leipzig aged 16-93 years, some of whom had lived in houses with water pipes containing lead from birth, were determined with a graphite furnace atomic absorption spectrometer. Results: The lead levels in tooth roots were in the range from 0.5 to 31.1 Î¼g/g dry weight (median 7.0 Î¼g/g). Significant differences were found in the lead concentrations in teeth between people living in houses with water pipes containing lead and those in houses without. Furthermore, the lead content depends on the age of the patient. The tooth lead of younger adults (aged 16-40 years) without additional lead exposure was in the range from 0.5 to 4.6 Î¼g/g dry weight (median 2.2 Î¼g/g), the range for the tooth lead of older dental patients (aged 61-93 years) was found to be from 6.6 to 6.8 Î¼g/g dry weight (median 6.7 Î¼g/g). In the case of patients living in houses with water pipes containing lead, the median lead concentrations in teeth were 7.2 Î¼g/g for younger adults and 14.5 Î¼g/g for older adults. Conclusions: Both previous occupational exposure to lead and non-occupational exposure can be detected in teeth many years after the end of exposure.

The influence of the cumulative long-term exposure to environmental sources (water pipes containing lead) on the bone lead level was investigated. Blood lead was found to be in the range from 10 to 101 Î¼g/l, with medians of 41 Î¼g/l in men and 31 Î¼g/l in women. The lead concentrations in the femur were in the range from 0.4 to 6.8 Î¼g/g dry weight with a mean of 2.7 Â± 1.3 Î¼g/g dry weight. The concentrations in the tibia were found to be higher, between 1.0 and 29.7 Î¼g/l dry weight with a mean of 8.4 Â± 6.8 Î¼g/g dry weight. The tibia lead levels of the participants in this study closely correlated with the length of time they had lived in old houses with lead water pipes. By determining the level of lead in the tibia, it is possible to estimate both previous occupational exposure to lead and non-occupational exposure.

The purpose of this investigation was to determine the blood lead levels of the general population in Leipzig. Moreover, the influence of the water pipes from lead on blood lead levels was investigated. Methods and subjects: Blood lead determinations were performed by atomic absorption spectrometry with a graphite furnace. Lead concentrations in venous blood were measured in 681 volunteers (18 to 68 years of age). Of these persons, 98 men and 94 women lived in houses with lead water pipes. Results: Median values of blood lead levels were significantly higher in participants with lead pipes than in those without lead pipes. The median values of blood lead levels were 68 Î¼g/l for men with lead pipes and 47 Î¼g/l for men without lead pipes. For women, the corresponding median values were 57 and 34 Î¼g/l, respectively. Conclusion: In spite of the relatively high percentage of persons with water pipes lead- containing, the geometric means of the blood lead levels for males (54 Î¼g/l) and females (42 Î¼g/l) obtained in the present study were similar to the values reported in other studies.

One of them containing 5'-phosphate group to be activated and 3'-phosphate group of the other being substituted with ethoxy-, buthylamino-, morpholino- or ethyl glycinate residues. Water-soluble carbodiimide (EDAC) proved to be more efficient in the phosphate group activation than N-hydroxybenzotriazole ester (yields of substituted pyrophosphates 35-80 and 10-15% respectively). The substituted pyrophosphate bong is quite stable in neutral aqueous solution. Mild conditions of selective cleavage of this bond yielding the initial oligonucleotides were found.
