Bronchiolitis is an acute viral disease of lower respitatory pathways in children under 2 years of age. It is manifested by coughing, whistling and refusing food intake. The most common cause of bronchiolitis is a respiratory syncytial virus. Vitamin D is a steroid hormone which is synthesized in the skin after sun exposure or food intake. With discovery of Vitamin D receptors and hydroxylated enzymes in immune cells, a potential role for Vitamin D in maintaining immune homeostasis was seen. It has been established that Vitamin D induces a change of the antimicrobial polypeptide, cathelicidin, which has both antibacterial and antiviral roles.

The most significant prostate diseases (PD) are benign prostatic hyperplasia (BPH), prostatic intraepithelial neoplasia
(PIN) and prostate cancer (PC). Generally, all PD are rare before the age of 50 with growing number of patients, primarily
with BHP, with each next decade, but about decade later the highest number of PIN and PC began to report. The aim of this
paper is to examine some of clinical, biochemical and histopathological characteristics of BPH, PIN and PC. Our sample
consisted of 169 men. Statisticaly the most common PD was BPH-77.5%, and the rarest PIN-8.3% (p<0.001). The average age of patients was 70.6±7.5 years (51-89) with no significant differences between diagnosis (p=0.415). PIN and PC are more often found in people from urban areas (p=0.004). In the central prostate area BPH is significantly higher in 88.5% (p<0.001). Peripheral parts are significantly more common places of PIN and PC (p<0.001). Median serum PSA values is statistically highest in PC-87.2 ng/ml (12.7-372.5), (p<0,001), especially those with predominantly peripheral parts localization. Gleason score is an important prognostic factor, with average value at PC is 7.32±1.4 (5-10), with a significantly higher values for diffuse PC. BPH is the most common, and PIN rarest PD. All diseases have occurred in people older than 50 years. Usually, BPH is in central and PIN and PC in peripheral prostate parts. PSA values were highest at PC, which is a prove of its importance in malignancy early detection.

The emergence of brain infarction depends to a great extent on the status of collateral blood circulation and is associated with hemodynamic instability. This kind of brain infarction is usually found in border vascular zones. Infarction of borderline fields arises between vascular territories ACA and ACM or between ACM and ACP, deep paraventricular infarcts in internal border zones, wound or triangular cortical infarcts, as well as major infarctions involving the entire irrigated territory of ACM.
