OSTEOSYNTHESIS OF COMPLEX COMMINUTED HAND BONE FRACTURES BY APPLYING THE LACING METHOD (A CLINICAL CASE STUDY).

Complex comminuted hand injuries are an urgent medical and social problem of national health systems, which is especially sensitive for countries with a low level of socio-economic development. The work aims to substantiate the effectiveness and safety of the shoelace method of hand bone osteosynthesis in complex comminuted fractures (a clinical case study). Clinical case: A 42-year-old female patient was admitted to the clinic with complaints of the presence of a crushed wound on the 2nd finger of the left hand. The shoelace method was applied for hand bone osteosynthesis. The surgical intervention time was 24 minutes, and the time before returning to work or daily activities equaled 7.1 weeks. The time to bone fusion was less than 45 days. The shoelace osteosynthesis method in complex comminuted fractures of the hand bones has prospects for modern clinical practice with the possibility of improving the performance and safety indicators.

Infective endocarditis in children--incidence, pattern, diagnosis and management in a developing country.

BACKGROUND: In developing countries, patients with infective endocarditis are referred late, there is low yield of blood cultures and incidence of rheumatic heart disease is still high. OBJECTIVE: Evaluate clinical pattern, assess diagnostic criteria in our settings and determine outcome. SETTING: A tertiary referral center for paediatric and adult cardiology. PATIENTS AND METHODS: All children with infective endocarditis admitted to a single center from April 1997 to March 2000 were analysed. The diagnosis was based on Duke's criteria, which proposed two major and six minor criteria. Minor criteria were expanded to include raised acute phase reactants and presence of newly diagnosed or increasing splenomegally. The patients were stratified as definite, possible and rejected cases. RESULTS: Of 1402 hospital admissions, 45 patients fulfilled the diagnostic criteria for infective endocarditis giving an incidence of 32 per 1000 hospital admissions. The mean age was 7.9 +/- 4 years (4 months to 16 years) with only two patients under 1 year of age. Rheumatic heart disease was the underlying lesion in 24 patients (53%) while congenital heart lesions occurred in 20 patients (45%). Previous antibiotic treatment was given in 26 patients (58%) definitely. Blood cultures were positive in 21 patients (47%); Streptococcus Viridans being the most common organism, while vegetations on echocardiography were present in 32 patients (71%). Surgery was undertaken in four patients and five patients left against medical advise. Of 10 patients with aortic valve involvement, there were three deaths (30%) and overall mortality was 13% (six patients). CONCLUSIONS: The incidence of infective endocarditis is 32 per 1000 (3.2%) hospital admissions in a tertiary paediatric cardiology referral center. Rheumatic heart disease is still the most common underlying heart lesion. Blood cultures are positive in less than 50% of cases and echocardiography in expert hands is a more sensitive tool in our set up. Mortality is still high and aortic valve involvement in particular, carried poor prognosis.
