[Clinical manifestations of cow milk protein intolerance in infants].

INTRODUCTION: The disorder of cow milk protein intolerance is characterised by a wide spectrum of clinical manifestations caused by hypersensitivity of type I, II, or IV, and occurs in 2-3% of children, mostly infants. OBJECTIVE: The aim of this study was to present our experiences and observations of clinical signs and symptoms of cow milk protein intolerance in infants aged below 12 months. METHOD: The investigation was carried out on a sample of 55 infants, aged between 1.5-9 months (X = 4.21 +/- 1.25), who had cow milk protein intolerance. Diagnosis of illness was based on characteristic anamnestic, clinical, and laboratory parameters, as well as on an adequate patient's response to antigen elimination. RESULTS: The clinical presentation of cow milk protein intolerance was dominated by cutaneous problems, found in 40/55 (72.73%) infants, followed by digestive disorders, found in 31 (56.36%), while respiratory tract disorders were observed least frequently (14.55%). None of the patients developed anaphylactic shock. Changes involving only one system were found in 35 (63.64%) patients; of these 20 (36.36%) were cutaneous and 15 (27.27%) digestive. Twenty (36.36%) infants displayed multisystemic changes; of these 12 were cutaneus with digestive, 4 were cutaneus with respiratory, while 4 infants had cutaneous, digestive, and respiratory disorders. Of the 55 infants with cow milk protein intolerance, 26 (47.27%) had urticaria, 22 (40.00%) perioral erythema, 21 (38.18%) diarrhoea (15 haemorrhagic, 6 non-haemorrhagic), 13 (23.64%) vomiting, 12 (21.82%) Quincke's oedema, 12 (21.82%) eczema, 5 (9.09%) obstructive bronchitis, while 3 (5.45%) infants had laryngitis. In 5 (9.09%) patients we found a significant body weight deficit and in 3 (5.45%), sideropenic anaemia, while longitudinal growth retardation was not registered in any of the patients. CONCLUSION: Our study showed that the disorder of cow milk protein intolerance predominantly involved cutaneous disorders as well as combinations of cutaneous and digestive disorders, while respiratory system disorders proved to be relatively rare.

[Molecular epidemiology of rotaviruses in preschool children].

Numerous epidemiological studies, conducted in both developed and developing countries, have shown that the rotavirus is an important aetiological agent in severe diarrhoeal diseases among preschool children. In recent years, different biochemical techniques for the genetic and phenotypic analysis of rotaviruses have been developed. The aim of this study was to define the biological and genetic differences among rotaviruses isolated from the faeces of affected children, by using the Polyacrylamide Gel Electrophoresis technique, as well as to type the viruses and establish the number of strains circulating within our population. In total, 124 faeces samples from children up to 5 years of age were analysed. With the use of the ELISA test, rotaviruses were isolated in 10.3% of cases. The extraction of viral RNA was carried out directly from the faeces samples, which was followed by electrophoresis, and finally observation using a UV lamp, and documentation with a photo camera. The analysis of viral RNA, using Polyacrylamide Gel Electrophoresis (PAGE), revealed equal mobility in all segments of the genome. The results of our analysis demonstrated that the same strains of rotaviruses do circulate within our population. Such a result can be explained as a consequence of our years-long isolation as well as of the decreased mobility of our population. However, the results do not signify that the rotavirus genome in this region will not be susceptible to variations and that, consequently, new strains will not be created.

[Rotavirus gastroenteritis].

Rotavirus is the main etiological agent that causes severe diarrheal diseases in newborns and young children up to two years. Every year, about one million children around the globe die of dehydration caused by Rotaviruses. The problem is even bigger in underdeveloped and developing countries. The results of our 18-month research, in the town Kragujevac and its surrounding area from December 1998 to May 2000 indicate that viruses are an important factor in the etiology of the acute diarrheal diseases in our population. In 124 children, aged 0 to 5, with the acute diarrheal diseases treated at the Pediatric clinic HMC "Kragujevac", viruses were the causes in 27% of the time. The Rotavirus belongs to the family Reoviridae. The infections caused by rotaviruses may be detected around the world. The incidence rate is higher in developed countries. The infection is transmitted orally. The entry of the Rotavirus infection is the upper part of the small intestine. The clinical picture is specific. The disease usually lasts four to seven days. The fastest diagnostic method is direct detection of viruses using the electronic microscope. The agglutination tests ELISA and LATEX are used for the examination of numerous samples. Only symptomatic treatment is required. High morbidity and mortality rates in developing countries are the reason to prevent the Rotavirus disease by active immunization.
