Adequate body hydration is considered the key element of fluid management in critically ill patients including group with end stage renal failure. Bioimpedance technique is widely used as a non-invasive, simple and accurate method to measure body composition. The purpose of the paper was to prescribe the using of single, and multifrequency bioimpedance spectroscopy technique for estimation of fluid balance in end-stage renal patients. We also discussed some measurements and data modelling problems, including postural change effect, and intercompartmental fluid shift during dynamic monitoring of fluid balance.

Sarcoidosis is a multi-organ granulomatous disorder of an unknown cause. Skin sarcoidosis occurs in about 20-35% of patients with systemic disease and may also arise in isolation. ⋯ The diagnosis rests on the presence of non-caseating granulomas on skin biopsy. Treatment and overall prognosis of cutaneous sarcoidosis is primarily dependent on the degree of systemic involvement.

Life saving surgery is the surgery which has to be performed during the acute or reanimation period (1 to 3 h) and during the primary or stabilisation period (first day surgery). During the reanimation period lifethreatening conditions are identified and management is begun simultaneously. Many trauma surgeons talk about the first "golden hours" as the time interval starting immediately after the injury when rapid intervention will save lives and a lack of intervention will result in life loss. ⋯ This period consists of further diagnostic procedures and treatment of injuries that are not directly life-threatening, but which may become life endangering or severely disabling if not treated promptly. The priorities of the surgical treatment are: brain injuries, eye- and facial injuries, progressive compression of the spinal cord, visceral injuries, musculoskeletal injuries. By improving prehospital care, rapid transport and last but not least immediate life saving surgical treatment preventable deaths can be reduced from 20-30% to 2-9% (5).

[Measurement of fluid compartments using electrical bioimpedance for assessment of target weight in hemodialysis patients].
The prescription of optimal hydration status in hemodialysis patients remains a much disputed topic in dialysis treatment. In particular, assessment of the patients optimal weight ("target weight") poses considerable difficulties. Multifrequency bioimpedance spectroscopy analysis (BIS) has been recommended as a non invasive, practical, and relatively non expensive method to determine hydration and nutritional status in patients on maintenance hemodialysis (HD). ⋯ In HD patients we observed higher range of TBW, and TBW/ECW ratio (from 15.6 to 56.1 L and from 0.33 to 0.78), as measured by BIS at pre-HD, and also post-HD period (TBW ranged from 13.1 to 56.2 L, ECW/TBW ratio ranged from 0.33 to 1.27). The TBW BIS results did not correlate with anthropometric calculation. We postulate using of multi-frequency bioimpedance technique in precise determination of fluid compartments and in consequence in the assessment of "target weight" in hemodialysis population.

Normal human development requires the compatibility between genetic sex (sex chromosomes), sex of gonades (tests or ovaries), genitalia (external and internal sex organs), somatic features (body characteristics) and psychic sex. The psychic sex, called frequently gender, consist of gender identity (self-estimation), gender role (objective estimation) and sexual orientation (hetero- or homosexual). It was believed that the psychic gender depends only on socio-environmental influences such as rearing, learning and individual choice. ⋯ In genetic men with the absence of male genitalia formation, caused by the aberrant function of androgen receptor, the gender identity depends on the severity of the disorder: female gender identity in the complete androgen insensitivity syndrome and female or male gender identity in the complete androgen insensitivity syndrome and female or male in the partial androgen insensitivity. These clinical observations confirm the experimental data indicating androgen role in the male gender identity creation. This knowledge is necessary for the decision of the direction of surgical correction of sex organs in children with ambiguous genitalia, which should not depend on the expected efficiency to perform sexual intercourse, but mostly on the expected or already present individual gender identity.
