[Preoperative radiation navigation in determining surgical strategy for liver echinococcosis]. / Predoperatsionnaya luchevaya navigatsiya v opredelenii khirurgicheskoi taktiki pri ekhinokokkoze pecheni.

OBJECTIVE: To analyze the technology for diagnostic modeling of liver echinococcosis. MATERIAL AND METHODS: In the Botkin Clinical Hospital, we developed a theory of diagnostic modeling of liver echinococcosis. Treatment outcomes were analyzed in 264 patients who underwent various surgical interventions. RESULTS: A retrospective group enrolled 147 patients. When comparing the results of diagnostic and surgical stages, we identified 4 models of liver echinococcosis. The choice of surgical intervention in the prospective group was based on previous models. Diagnostic modeling reduced the number of general surgical and specific complications, as well as mortality in the prospective study group. CONCLUSION: The technology for diagnostic modeling of liver echinococcosis made it possible not only to identify 4 models of liver echinococcosis, but also determine the most optimal surgical intervention for each of model.

Occupational exposure to carbon monoxide during charcoal meat grilling.

Charcoal meat grill workers are one of the many occupational groups that are subject to carbon monoxide exposure. This group have often been overlooked and not investigated. Carboxyhemoglobin (%COHb) levels in 100 male workers were assessed before work and after work the same day. Carboxyhemoglobin levels increased significantly after work in both smoking and nonsmoking workers. The mean COHb levels for smoking workers before work was 3.8% and for nonsmokers was 2.4%, whereas after work, the mean COHb level for smokers increased to 8.1% and for nonsmokers to 6.2%. These elevated mean COHb levels exceed the 5% COHb level recommended by WHO and NIOSH. With respect to smokers only, 36 (81.8%) workers after work exceed 5%, whereas the nonsmokers, 29 (51.8%) of the workers exceed 5%. These results indicate that charcoal meat grilling workers are exposed to significant levels of carbon monoxide. Several control measures have been suggested to mitigate exposure to carbon monoxide.
