Introduction/Objective. Benign transient hyperphosphatasemia (BTH) is a pathogenetic insufficiently clear clinical entity that is mostly seen in infants and young children. The objective of this paper is to present our experience regarding the age of occurrence, the conditions of the discovery, and the length of duration of BTH in children. Methods. The study was realized on a sample of 18 children, nine boys and nine girls, aged 10–42 (21.06 ± 9.35) months with BTH. The diagnosis of BTH is based on the absence of bone and hepatobiliary diseases, and its spontaneous disappearance over the course of several months. Results. One patient was in the first year, 13 in the second, three in the third, and one in the fourth. Isolated high activity of serum alkaline phosphatase, which was 2.04–21.9 (8.05 ± 5.31) times above the upper reference value for the corresponding age, in 14 cases it was found during the acute diarrhea, and in four with acute rhinopharyngitis, of which in two complicated with otitis media. The cause of diarrhea in six cases was rotavirus, in two Campylobacter, and in one adenovirus, and otitis media in one case was caused by Streptococcus pneumoniae, while in others, etiologic factors of infection were not identified. Spontaneous normalization of serum alkaline phosphatase activity was recorded between one and three months after the onset. Conclusion. BTH is a harmless biochemical disorder that spontaneously subsides within three months after initial observation. It is found randomly as a routine laboratory finding most often within the treatment of acute gastrointestinal and respiratory infections.

Introduction. Sonography is a useful technique for the investigation of a number of musculoskeletal disorders. The most common indication for ultrasonography of muscles and tendons is the diagnosis of traumatic lesions, distinguishing them from other disorders and follow-up of healing process. Objective. The purpose of this paper is to show the importance of ultrasound in the diagnosis of muscle and tendon injuries. Methods. The study included 170 patients (148 male and 22 female), mean age 29.6 years (range 14-60 years). All examinations were performed by linear transducer of 7.5-10 MHz, with longitudinal and transverse scanning. Ultrasound examination followed physical examination. Results. Traumatic lesions of muscles were diagnosed in 113 patients (66.7%) and tendon injuries in 57 cases (33.2%). The muscle changes detected by ultrasonography were the following: 70 (61.9%) partial and two (1.76%) complete ruptures, 22 (19.46%) haematoma, 9 (7.96%) strains grade I, 4 fibroses and 4 ossifying myositis 4 (3.5%, respectively). Complications of muscle injuries were diagnosed in two cases, a muscular hernia and an arteriovenous fistula. Among tendon injuries, 21 (33.8%) ruptures and 36 (66.1%) tendinitis were diagnosed. Accompanying effusion in the bursa of patients with tendon injuries was found in 9 cases. Conclusion. Ultrasonography allowed visualization and objective assessment of the type and the extent of traumatic pathomorphological changes of muscles and tendons. Such diagnostic possibilities of ultrasonography are especially important in the choice of appropriate therapy.
