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.

Sindrom opstrukcijske apneje u spavanju (SOAS) je poremećaj disanja u kome se javlja delimična ili potpuna opstrukcija gornjih disajnih puteva, što ometa normalnu ventilaciju pluća i tako remeti normalan obrazac spavanja. Klinički se ispoljava habitualnim hrkanjem, često udruženim sa zastojem u disanju, i znacima napornog disanja tokom spavanja, kao i različitim neurobihejvioralnim problemima koji se javljaju tokom dana. Neprepoznat i nelečen SOAS može dovesti do trajnih, pa i životno opasnih posledica. Svaki pacijent sa smetnjama disanja vezanim za spavanje trebalo bi da bude podvrgnut polisomnografskom ispitivanju tokom noći.

Cardiac dysrrhythmias can be found in patient with no signs of ischemic cardiac disease but supraventricular and ventricular arrhythmias can be developed in cardiac hypertrophy. In this work we have examined frequency of cardiac dysrrhythmias in patients with hypertension and with or without hypertrophy of left ventricule (LVH). Investigation was accomplished on 80 patients with high blood pressure. In all 80 patients, basic on ECHO signs we define LVH, and by using of Holter monitoring we analised dysrrhythmias. Basic on ECHO signs we have 2 groups of patients: I.group ECHO (+) LV, and II group ECHO (-) LVH, in each 40 patients. Holter monitoring have 37 patients [22 mans (59,45%) and 15 women (40,54%)]. Hypertensive patients with LVH, who hade dysrrhythmia, have middle value IMLV 155,3 ± 27,21; аgе 56,42 ± 6,04; duration of hypertension 11,73 ±10,05; and EF% 55,2 ± 3,77. In patients with Holter monitoring 16 ( 43,32%) have dysrrhythmias type II, IIIa, IIIb and IV Lowny degree, (12) 34,43% from 43,32% have LVH. Salves VES are registrated only in group hypertension patients with ECHO(+) 5,4%. By using Mann Whitney statistic test for presents of dysrrhythmias in 2 groups of patients (ECHO LVH and ECHO without LVH), we found statistics significants (p = 0,049). In IMLV 60-110 g/m² 8,82% patients have dysrrhythmia, IMLV 151-200 g/m² dysrrhythmias are registrated in 40%; and 50% patients have dysrrhythmias in IMLV> 200g/m². In group hypertensive patients with LVH dysrrhythmias are registrated in group with ecscentric LVH 35,1%

Eosinophilic Granuloma (EG) represent the most benign and localized form of the three Langerhans cell histiocytosis syndromes. In bone, it is a tumor-like proliferation Langerhans cells. Intraosseous EG lesions can be solitary or multifocal. EG accounts for 60-70 % of Langerhans cells histiocytosis cases. The authors are describle a 21 year-old men with Eosinophilic granuloma. The disease had a rarely course with disorders multiple lesions in bones

The frequent sign in renal disease and disease of urinary tract is presents of blood in urine, hematuria, and it is discovered very often in children. Aim of this work was to establish the most frequent causes of hematuria in our recorded
material. Investigation was accomplished on 60 patients, by using standard clinical and biochemical methods. The results of
work have showed that hematiria may be faund in any age in children. Most patients belong to age 5-10 years 27 (45.0%),
belong to age up to 10 years, and 26,6% belong to age 1 -5 year. Hematuria is more common in school-aged children and in
adolescence. Gross hematuria is found in 60% of patients, and microscopic hematuria in 40% of patients. Infective cause of
hematuria is found in 29 patients, and in 31 patients other causes, such as : stones, sec.glomerular diseases, tumors, hematologic disorders, etc. As infective glomerular disease and infection of urinary tract, in 25 % patients the cause of hematuria is acute poststreptococcal glomerulonephritis, tuberculosis in 6,66 patients,urinary tract infecion in 16,6 patients (in 8,33% patients caused by E.colli). Anatomic abnormalities is found in 15% patients,asymptomatic hematuria in 6,6%, lithiasis in 5%, and Henoch - Schönlein in 5%, and coagulopathies in5 % of patients, other causes are rare.In observed sample of patients, we have registrated high frequency of hematuria in chlidren with ac. poststreptoccal glomerulonephritis, then in children with morphological abnormalitis of urinary tract,urinary tract infection, and IgAnephropathia as a very rare cause, but Trachtman and Hagg in their reserches found Alport syndrom and IgA nephropathy as a most frequently causes of Hematuria
