Chronic diarrhea in children has a long differential diagnosis, but the clinician can usually distinguish disease from functional diarrhea. A careful history will provide information on medical and dietary problem, growth disturbance, associated symptoms and signs. The extent of laboratory evaluation should be guided by common sense. In the absence of the worrisome historical items noted, or abnormal findings on examination or growth history, reassurance may be all that is required. This article reviewed the diagnostic approach and differential diagnosis of chronic diarrhea, and summarized common non pathologic conditions of chronic diarrhea such as chronic nonspecific diarrhea (toddler's diarrhea) and secondary lactase deficiency.

PURPOSE: The aim of this study was to investigate the age of onset and the prevalence of lactose malabsorption in early childhood in Korea. METHODS: We conducted a study of lactose malabsorption by breath hydrogen test in healthy children aged between 25~96 months old. Standard lactose loading (2 g lactose/kg, maximum 40g) test was done in 129 children and cow's milk (10 mL/kg) loading in 126 children followed by breath sampling of 60 and 120 minutes after the loading. An increase above baseline of 20 ppm or more was used as a criteria for positive responses. RESULTS: The prevalence of lactose malabsorption was 7% in 25~36 months old, 19% in 37~48 months old, 35% in 49~60 months old, 55% in 61~72 months old, 82% in 72~84 months old, 80% in 85~96 months old children. Only 1% of the children showed positive result in breath hydrogen test after the cow's milk challenge. CONCLUSION: The prevalence of lactose malabsorption was increased between 37 months and 60 months of age, reached to adult level of prevalence after 72 months of age. When physiological dose of lactose was used as the challenge, the number of lactose malabsorbers become clinically insignificant.

OBJECTIVE: To study the efficacy and safety of lactase additive in improving lactose intolerance in preterm infants. METHODS: A total of 60 preterm infants with lactose intolerance who were admitted to the Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2019 were randomly divided into a lactase treatment group and a control group, with 30 infants in each group. The infants in the lactase treatment group were given 4 drops of lactase additive (180 mg) added into preterm formula or breast milk, and those in the control group were given placebo, oral administration of probiotics (live combined RESULTS: Finally 29 infants in the lactase treatment group and 26 infants in the control group completed the trial. At the end of the first week after intervention, compared with the control group, the lactase treatment group had significantly lower frequency of daily milk vomiting and gastric retention amount ( CONCLUSIONS Lactase additive can safely and effectively improve the clinical symptoms caused by lactose intolerance in preterm infants.

OBJECTIVES: This study examined the milk intake patterns with lactose and milk fat in Korean male adults using the following variables: milk intake level, awareness of lactose, and milk fat, health problems, and necessity of milk intake. In addition, the factors affecting milk intake were analyzed by multiple regression analysis. METHODS: The subjects were 532 males aged 20 years or older among the nationwide milk purchasing group. The subjects were 223 (41.9%) in the 20–29 year age group, 188 (35.3%) in the 30–49 year age group and 121(22.7%) in the over 50 year age group. The survey was conducted using ANOVA and multiple comparative analysis to examine the differences in age and multiple regression analysis was performed to investigate the factors affecting the intake of milk. RESULTS: The intake of milk in the subjects was 538.14 ± 494.23 ml per week. There were statistically significant differences in the subjects' age according to processed milk, low fat, nonfat milk, cheese, and ice cream. The perception of milk and lactose and milk fat was recognized as a good food for skeletal health when milk was consumed. Among the milk nutrients, lactose was highly recognized at the age of 20–29, and milk fat was recognized in those over 50 years. In addition to lactose and milk fat, calcium was the most highly recognized among the milk nutrients. Health problems associated with milk were skeletal health, obesity, and lactose intolerance. The perception of lactose intolerance was related to lactose intolerance and fatness, and the dietary behavior was unaffected. CONCLUSIONS: This study examined the milk intake patterns of adult Korean males. Many variables were found to be related to the intake of milk. In this study, the milk intake was high when there was no problem with the perception and dietary behaviors of milk nutrition (lactose and milk fat). This study focused on lactose and milk fat, which are major nutrients in milk, and it is a new perspective study among milk-related research.

PURPOSE: The activity of epithelial lactase (LCT) is associated with a polymorphism 13910 bp upstream in the lactase encoding gene. Because the association between the LCT-13910 polymorphism and the risk for colorectal cancer is not clear, we investigated the role of the LCT-13910 polymorphism as a potential risk factor for colorectal cancer and colorectal polyps in the Turkish population. METHODS: One hundred sixty-six subjects (74 with polyps, 44 with colorectal cancer, 48 controls), who had undergone a total colonoscopy between January 2012 and November 2012 in our endoscopy unit were genotyped for the LCT-13910 polymorphism by using the polymerase chain reaction and minisequencing. RESULTS: The CC genotype in the lactose gene 13910 locus, which is accepted as the genetic indicator of lactase deficiency, was determined as 83.7%. The CC genotype rate was determined as 89.1% in patients who had a history of lactose intolerance and 81.5% in those without a history of lactose intolerance (P = 0.236). No difference was detected between the patients who had colorectal polyp(s) and/or cancer and the controls with regard to the LCT-13910 polymorphism. No differences were determined between groups when they were compared with regard to the C or the T allele. CONCLUSION: No differences were detected between the patients who had colorectal polyp(s) and/or cancer and those with normal colonoscopy findings with regard to lactase gene polymorphisms. No differences were determined between the groups when they were compared with regard to the C or the T allele.

The side effects of rheumatoid arthritis (RA) medication, such as irritation and ulceration of the gastrointestinal mucosa, have been observed and many patients find it difficult to swallow tablets and hard gelatin capsules. This results in a high incidence of noncompliance and ineffective therapy towards treating RA. Fast-dissolving and fast-dispersing drug delivery systems may offer a solution to these problems, and as a result, fast disintegrating tablets are gaining prominence as a new drug-delivery system; one such system is the binding of the active ingredient with lactose. There have been no reports on the rate of lactose intolerance against medication in patients with newly diagnosed RA, because lactose intolerance has not been associated with particular problems with most existing RA therapies. We encounterd a 56-year-old lactose intolerant female patient who had severe diarrhea after receiving drugs to treat her newly diagnosed RA.

OBJECTIVETo find out the diet measurements for alleviating symptoms of lactose intolerance when people had had a drink of milk.

METHODSEight lactose intolerance (LI) subjects suffering from watery diarrhea were selected from 38 subjects by using hydrogen breath test (HBT) joined the test of drinking cow's milk along with various other foods designed by orthogonal trial. The 100 healthy college students were selected to observe symptoms after they ingested 25 g milk powder in different manners.

RESULTSThe breath-hydrogen concentration in groups with ingesting milk and various other foods was lower than those with ingesting milk only. Egg was better than mantou in alleviating symptoms. (F vaule of stool lactose and symptom score were 7.5, 9.0, respectively, P < 0.05). Whole wheat bread might aggravate flatus. The prevalence of the symptom in 100 college students by drinking milk in fasting state (27/98) was significant in comparing with those drinking milk in regular meal (13/98), chi2 = 6. 156, P < 0. 05.

CONCLUSIONThe study demonstrated that different kinds of food, and different milk drinking manners should affect the intolerance symptoms. We suggested: should not drink milk in fasting state, and drinking milk together with egg and staple food such as steamed bread, bread or gomuti should be the best choice for breakfast. Drinking milk with regular manner might alleviate the symptoms of intolerance. For avoiding lactose intolerance, whole wheat bread should not be taken along with milk.

In 1962, Durand suggested the term primary lactose intolerance for the disorder withch resulted from a defect of the lactase activity in the intestinal mucosa. However primary lactose intolerance is rare and it is not commonly encountered in routine pediatric practice. Apart from such a primary lactose intolerance, diarrhea, meteorism, and abdominal discomfort after taking lacose containing food are more frequently encoumtered in case of gastroenteritis in which damage of the intestinal mucosa and coating of the mucosa by inflammatory secretions lead to decreased lactase it form the primary lactose intolerance. It is now considered that secondary lactose intolerance may play an important role in case of infantile diarrhea commonly encoutered in pediatric practice. The auther tried the lactase preparation Galantase?to evaluated it's clinical effect on infantile diarrhea of various kind (50 cases). Evaluation of the effect of Galantase was made on the bases of the following criteria. l Marked effective ; nature of stools and number per day returned to normal within 3 days after Galantase administration. l Effective ; nature of stools and number per day decreased within 3 days after Galantase administration. l Ineffective ; all stools remained unchainged and diarrheic. The results obtsined by this study are as followes l Marked effective ; 78 % l Effective ; 12 % l Slight effective ; 4% l Ineffective ; 6% There was no undesirable side effect observed in all 50 cases. Based upon the above effective rate, we concluded that the Galantase is a quite effective medicament for infantile diarrhea, especially for primary and secondary lactose intolerance.
