Febrile seizures are the most frequent neurological disorder in the childhood. According to American Academy of Pediatrics (AAP), they have been defined as seizures provoked by high temperature in children aged between 6 months and 5 years, without previous history of afebrile seizures, intracranial infections and other possible causes of seizures. Seizures can be typical and atypical, according to the characteristics. Pathogenesis of this disorder has not been clarified yet, and it is believed to be a combination of genetic factors, high body temperature and brain maturation. The risk factors for recurrence of febrile seizures are: age in which seizures appeared for the first time, epilepsy in the first degree relative, febrile seizures in the first degree relative, frequent diseases with fever and low body temperature on the beginning of seizures. The frequency of recurrent seizures The risk for occurrence of epilepsy in children with simple seizures is about 1-1.5%, which is slightly higher compared to general population, while it increases to 4-15% in patients with complex seizures. However, there is no evidence that therapy prevents occurrence of epilepsy. When the prevention of recurrent seizures is considered, it is necessary to separate simple from complex seizures. The aim of this paper was to analyze the most important risk factors for febrile seizures, and to evaluate their impact on occurrence of recurrent seizures. Our study included 125 children with febrile seizures, aged from 6 months to 5 years. The presence of febrile seizures and epilepsy in the first degree relative has been noted in 22% of children. Typical febrile seizures were observed in 76% of cases, and atypical in 24%. Most patients had only one seizure (73.6%). Children, who had seizure earlier in life, had more frequent recurrences. Both risk factors were present in 25% of patients, while 68% of patients had only one risk factor. For the children with febrile disease, primary risk factors were the level of body temperature and a family history of febrile seizures. The risk for febrile seizures in these children was 10,4%, which is more than a twice as high compared to general population, which is 4%. Is between 10% in children without risk factors and 50-100% in children with three or more risk factors.

Rickets presents osteomalacia which is developed due to negative balance of calcium and / or phosphorus during growth and development. Therefore it appears only in children. The most common reason of insufficient mineralization is deficiency of vitamin D, which is necessary for inclusion of calcium in cartilage and bones. As result, proliferation of cartilage and bone tissue appears, creating calluses on typical places. Bones become soft and curve, resulting in deformities. Our present study included 86 infants, in whom, besides other diseases, clinical and laboratory signs of rickets were identified. In our study, rickets is most common (82.5%) in infants older than 6 months. By clinical picture, craniotabes is present in 46.5% of cases, Harisson groove in 26.7%, rachitic bracelets in 17.4%, rachitic rosary in 17.4% and carpopedal spasms in 2.3% of cases. Leading biochemical signs of vitamin D deficient rickets is hypophosphatemia (in 87.3% of cases), normal calcemia (in 75.6% of cases) and increased values of alkaline phosphatase (in 93% of cases). It has been shown that rickets in infant age may later affect higher incidence of juvenile diabetes, infection of lower respiratory tract, osteoporosis, and so on.

Breast cancer is mostfreqency malignant tumor in womans, cardinal causer of death in malignant tumots with continous ascendig of incidence and mortality. Actual therapy of breast cancer is multidisclipinary to consist in surgical, irradiant, cytostatic, hormonal and imunological therapy with specific directive based in disease stage. Surgical therapy is now more effectiveness metod of therapy and base of multidisclipinary therapy. In aim of prognosis desease conclusion and risk ratio of local relapse in currency is prognostic factors. With combination a few factors derive prognostic indexes with whose can acquire more information aggainst biologic behaviour of each neoplasm.
