Beach handball is a growing sport without available scientific data on the type of injuries that occur. The aim of this study is to record the incidence rate, type and severity of injuries in this sport. During the finals of the European Beach Tour 2014, 122 beach handball players completed a self -report questionnaire about the injuries they had sustained during the previous 24 months. The injury incidence rate for male and female was 12/1000h and 11.36/1000h respectively during games, and 1.8/1000h and 4/1000h during training accordingly. Muscle strains were the most common type of injury, while the majority of injuries affected the knee. The return to sports period was within 2 weeks from injury for 62% of male and 64.5% of female athletes. Statistical analysis could not correlate the incidence or severity of injuries in beach handball to any of the analyzed variables. This study showed that injuries in beach handball are similar to team handball, rather than to other "sand" sports.

We studied the antitumor activity of Navelbine (NVB) together with its ability to induce cellular differentiation and to influence estrogen receptor status of Lewis lung carcinoma (LLC). A total of 32 C₅₇B1 mice divided into 5 groups were used for transplantation of LLC. Four groups of mice were treated with 5.0, 2.5 and 1.25 mg/kg/day from day 1 to 9 and 1.25 mg/kg on days 1, 7 and 13. Eight mice were controls. The dose of 1.25 mg/kg/day was the most effective and produced 72.7% inhibition of tumor growth. Ultrastructurally, on day 1 the cells showed poor differentiation. On day 14, in the case of 72.7% inhibition of tumor growth the study revealed a significant restoration of the morphology of the cells. Estrogen receptors gave a positive value in contrast to the initial measurement which was negative. The present study demonstrated good antitumor activity of NVB on LLC. NVB may also induce cellular differentiation and influence the estrogen receptor status.
