The aim of the study was to analyze the tendencies of public and private health care expenditure in Lithuania during 1994-1999. Crude examination of statistical data show, that the growth rate of health care spending per capital is largely determined by growth of national gross domestic product (GDP). We have estimated that health care spending in Lithuania have risen twice faster than GDP during 1994-1999. (Percentage of rise in health care spending, divided by percentage rise of GDP, is +2.26). ⋯ The tendency of increasing private spending shows, the evidence, that households are facing more financial risk of purchasing health care. This should be an implication for health care policy makers. Further decisions to increase private payments have to be based on evidence after detailed analysis of impact of consequences on health care access for various social economic groups of population.

Infection with high-risk human papillomaviruses is a significant risk factor of various benign and malignant human lesions in the upper respiratory tract, skin and the genital tract. The identification of particular human papillomaviruses types is important for identifying patients with premalignant lesions who are at risk of progression to malignancy. Our aim was to establish the prevalence of human papillomaviruses infection in the upper respiratory tract of patients with laryngeal papillomatosis, to identify viral types, to evaluate the relationship between some risk factors and persistence of human papillomaviruses in the upper respiratory tract and to determine the pattern of human papillomaviruses infection. ⋯ The prevalence of human papillomaviruses infection in the upper respiratory tract of patients with laryngeal papillomatosis is high; human papillomaviruses 6, 11 types are predominant. High-risk human papillomaviruses were noted statistically significantly more often in the group of patients with laryngeal papillomatosis. Inclination to diseases of respiratory system, dental caries, smoking, low living standard are statistically significantly related to human papillomaviruses persistence in the upper respiratory tract.

Adrenogenital syndrome, or so called congenital adrenal hyperplasia, is caused by a congenital insufficiency of the enzyme 21-hydroxylase, which is responsible for converting cortisol into cholesterol. Because of virilizing effect of androgens overproduction girls develop clitoral hypertrophy and persistent urogenital sinus (common channel for urethra and vagina). Surgical treatment is recommended in order to repair those developmental faults. ⋯ Postoperatively the patients were observed for 0.5-5 years, the close results showed to be good. There were 4 cases of vaginal stenosis and 2 cases of urethrovaginal fistula (all successfully repaired later). Early one staged genitoplasty and postoperative vaginal dilatations for the period of 6-12 months is recommended.

Under the influence of strong electric fields the permeability of tumor cell membranes to poor permeating drugs increases and as a result the tumor growth is inhibited. This new tumor treatment method is named electrochemotherapy. We investigated the electrochemotherapy influence of bleomycin upon mice Lewis Lung Carcinoma by using optical histological and electron microscopic tumor analysis. ⋯ Cell and nucleus membranes break as well as hemorrhage are very often. The observable histological tumor change was noted when electrical pulses of 1300 V/cm and 0.1 ms duration were applied. Pulses of 1700 V/cm and 0.1 ms duration induce total tumor destruction.
