[Determination of milk and diary products consumption and their connection with lactose malabsorption or lactose intolerance in selected disorders of the alimentary tract in children]. / Ocena spozycia mleka oraz produktów mlecznych i jego zwiazku z uposledzonym trawieniem i wchlanianiem laktozy lub nietolerancja laktozy w niektórych chorobach przewodu pokarmowego u dzieci.

UNLABELLED: Lactose stimulates proliferation and colonization of acidophilic bacteria, which due to fermentation processes lower colonic pH and simplified absorption of some microelements from the intestine. However, the common problem in children is intolerance of this carbohydrate. Treatment, quite simple, is based on partial or total elimination of lactose from diet. Some substitutional products with equivalent nutritional value should be introduced to prevent deficiencies symptoms during lactose-free diet. THE AIM OF THIS STUDY: Determination of milk and dairy products consumption and their connection with lactose malabsorption or lactose intolerance in children above 5 years of age in selected disorders of the alimentary tract: food allergy, celiac disease, secondary enteropathy, functional dyspepsia, irritable bowel syndrome and deficiency of body weight and height. MATERIAL AND METHODS: The number of 301 patients above 5 years of age (135 boys and 166 girls; mean age 11.5 years) were included into the study. Milk and dairy products consumption habits, lactose intolerance symptoms, hydrogen breath test, activity of lactase and villous atrophy were investigated. RESULTS: Decreased sweet milk consumption from, 33.33% in children with food allergy to 55.38% in children with functional indigestion was observed, in spite of gastrointestinal complaints after ingestion of milk. The biggest lactose malabsorption and lactose intolerance frequency was observed in children with decreased sweet milk consumption due to complaints after ingestion of milk and in children who didn't drink milk. There were no statistically significant difference between frequency of lactose malabsorption and lactose intolerance symptoms in children with different dairy products consumption habits. There were no statistically significant difference between frequency of hypolactasia in children with different sweet milk or dairy products consumption habits. CONCLUSIONS: Frequent (33-55%) decreased sweet milk consumption in children in spite of clinical symptoms after ingestion of milk was observed. The biggest lactose malabsorption and lactose intolerance symptoms frequency was observed in children who didn't drink milk and in children with decreased consumption of sweet milk due to complaints after ingestion of milk. There were no statistically significant difference between frequency of lactose malabsorption and lactose intolerance in children with different dairy products consumption habits.

[Lactose intolerance: pathophysiology, clinical symptoms, diagnosis and treatment]. / Nietolerancja laktozy: patofizjologia, objawy kliniczne, rozpoznanie i leczenie.

Lactose malabsorption and milk products intolerance symptoms are the most common alimentary tract disorders. Lactose intolerance is a result of lactase deficiency or lack of lactase and lactose malabsorption. Three types of lactase deficiency were distinguished: congenital, late-onset lactase deficiency and secondary lactase deficiency. Lactose intolerance means the appearance of clinical gastrointestinal symptoms after ingestion of lactose. To the clinical symptoms of lactose intolerance belongs: nausea, vomiting, abdominal distension, cramps, flatulence, flatus, diarrhea and abdominal pain. The diagnosis of lactose intolerance is based on the breath hydrogen test and analysis of lactase activity in the small intestine mucosa. Dietary treatment eliminates clinical symptoms.

[Acute pancreatitis as a complication of diagnostic gastroduodenal endoscopy at 10 years old girl--case report]. / Ostre zapalenie trzustki jako powiklanie gastroduodenoskopii diagnostycznej u 10-letniej dziewczynki--opis przypadku.

A 10-years old girl with chronic pancreatitis, in whom the symptoms of acute pancreatitis appeared after gastroduodenal endoscopy is described. One hour after endoscopy the following symptoms appeared: unigastric and epigastric pain, intense vomiting, elevated amylase activity in the serum (2744 micro/l) and in urine (23738 micro/l) as well as serum lipase activity (4350 micro/l). Ultrasound of the abdomen revealed the enlargement of the pancreas with hypodense structure in comparison to the examination conducted couple hours earlier, and trace of fluid around the pancreas. In the treatment intravenous omeprazole, a strict diet and intravenous fluid and electrolytes were administered. After two days vomiting and abdominal pain subsided, biochemical results improved and the reduction of pancreas dimensions in ultrasound study was observed.

[Determination of lactose intolerance frequency in children with food allergy]. / Ocena czestosci wystepowania nietolerancji laktozy w alergii pokarmowej u dzieci.

UNLABELLED: Lactose malabsorption and lactose intolerance symptoms are the most common alimentary tract disorders in children. Lactose intolerance is a result of lactase deficiency or lack of lactase and lactose malabsorption. Hypersensitivity in food allergy is connected with the presence of specific IgE (specific antibodies against some allergens) or lymphocytes. Lactose intolerance and food allergy may coexist in the same patient. AIM: The aim of this study was determination of lactose intolerance frequency in children with food allergy who were below and above 5 years of age. MATERIAL AND METHODS: The number of 87 children with food allergy aged from 0.7 to 18 years were included in the study (48 boys and 39 girls). 51 patients above 5 years of age and 36 patients below 5 years of age were studied. Lactose intolerance symptoms, hydrogen breath test, activity of lactase and villous atrophy were investigated. RESULTS: Decreased absorption of lactose in hydrogen breath test was observed in 28% of children above 5 years of age and in 5% in younger children. Positive result of biological trial in hydrogen breath test was observed in 10% of patients who were below 5 years of age and in 26% patients above 5 years. There was no statistically significant difference in lactose intolerance frequency and in decreased activity of lactase in intestinal mucosa between these two groups. Frequent partial villous atrophy was observed in younger patients (41,38%) than in children above 5 years of age (17.86%). CONCLUSIONS: Lactose intolerance was observed in 10% patients who were below 5 years of age and in 26% patients above 5 years of age with food allergy. There was no statistically significant difference between these two groups.

[Williams syndrome in 2-year-old boy]. / Zespól Williamsa u 2-letniego chlopca.

In the course of Williams syndrome, in 15% of the cases, transient hypercalcemia is present. Additionally, in patients with this syndrome celiac disease is more frequent than in general population. In present work, a case of 2-years-old boy with hypercalcemia, deficiency of the body mass in whom Williams syndrome had been diagnosed in 15th month of life, was described.
