Hereditary galactosemia is a biochemical genetic disease due to a deficiency of galactose-1-phosphate uridyltransferase (GALT) enzyme activity (OMIM 606999). Acute manifestations occur in the neonatal period and are, with rare exceptions, related to lactose ingestion. They include poor feeding and growth, emesis, jaundice, liver disease, bleeding diathesis, anemia, renal tubulopathy, cataracts, encephalopathy and death from E. coli sepsis. Chronic manifestations, which also develop in prospectively treated patients, involve (a) the brain, resulting in delayed language acquisition, speech defects, and learning problems, and (b) the ovary, in the majority of females, producing hypergonadotropic hypogonadism. The serum FSH level is elevated in infancy/early childhood in many, but not all patients with a severe phenotype. There are few reports of patients with classic galactosemia having undergone pregnancy, labor, and delivery. The pathologic findings in the ovary, including a persistence of primordial follicles and streak gonads, have been variable. The etiology of primary ovarian insufficiency (POI) in galactosemia is unknown. Clinical surveillance includes screening for abnormalities in ovarian function at an early age. Treatment consists of estrogen/progesterone supplementation at the appropriate age. Reduced BMD has been reported. Future research is needed (1) to delineate the mechanisms behind reduced ovarian function in these young women; (2) to determine the timing of the lesion: prenatal, postnatal, and both pre- and postnatal; (3) to determine whether elevated galactose-1-phosphate is both necessary and sufficient to induce primary ovarian insufficiency; and (4) to understand the mechanism(s) behind the reduced BMD seen in children and adolescents with galactosemia.

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 gastroenteritis (AGE) is a typical illness seen in outpatient children, usually treated by Family Pediatricians (FP). To analyze the characteristics of community AGE, we have collected all the case histories of children observed in a FP office, analyzing computerized clinical file (FIMED Infantia), taken from the period 2003-2007. We enrolled 1140 children with AGE were gathered, for an average of 228 cases/year; 578 (51%) males and 562 (49%) females; the month with highest number of cases is October (120 cases, 10.5%), followed by September and April (105 cases in both, 9.2%). The month with the lowest incidence is February (75 cases, 6.6%) followed by August (81 cases, 7.1%); children's mean age is 4.6 +/- 3.4 years with a wide range (10 days divided by 16 years). As regards the clinical pattern, 314 children (27.5%) presented high fever, 395 (34.6%) vomiting and 24 cases (2.1%) bloody diarrhea; mean daily stools is 3.9 +/- 1.1; only 4 children suffered from severe dehydration. 255 children (22.4%) received antibiotic prescription, mainly cotrimoxazole (51%), followed by cephalosporins (39%) and macrolides (10%); 893 children (78.3%) were prescribed probiotics. Oral rehydrating solution was always offered to all children, followed by normal diet and only 4 children (0.4%) need the administration of a lactose free formula. Mean duration of diarrhea was 3.4 +/- 1.7 days, only 10 children (0.9%) suffered from chronic diarrhea and only 2 children (0.2%) were hospitalized due to severe dehydration. In conclusion, the child that refers to the FP office, is often a child with minor symptoms, for whom admission is not required; he/she presents a regular course and slight complications.

OBJECTIVE To determine the effects of oral gabapentin administration prior to veterinary examination on signs of stress in cats. DESIGN Randomized, blinded, crossover clinical trial. ANIMALS 20 healthy pet cats with a history of fractious behavior or signs of stress during veterinary examination. PROCEDURES Cats were scheduled for 2 veterinary visits 1 week apart and randomly assigned to receive a capsule containing 100 mg of gabapentin (13.0 to 29.4 mg/kg [5.9 to 13.4 mg/lb]) or placebo (lactose powder) prior to the first visit and the opposite treatment prior to the second visit. Owners were instructed to administer the assigned capsule orally 90 minutes prior to placing the cat into a carrier and transporting it to the veterinary hospital. Standardized physical examinations and blood pressure readings were performed. Owners assigned a cat stress score during transportation and examination, and the veterinarian assigned a compliance score at the visit. Scores were compared between treatments, controlling for various factors. RESULTS Owner-assessed cat stress scores during transportation and veterinary examination and veterinarian-assessed compliance scores were significantly lower when cats received gabapentin than when they received the placebo. Sedation was a common effect of gabapentin administration, and ataxia, hypersalivation, and vomiting were also reported. All effects resolved within 8 hours after gabapentin administration. CONCLUSIONS AND CLINICAL RELEVANCE Owners' perception of stress in their cats is a primary reason for failing to seek veterinary care. Results of this study suggested that gabapentin is a safe and effective treatment for cats to help reduce stress and aggression and increase compliance for transportation and veterinary examination.

Classical galactosemia is an inherited disorder of the carbohydrate metabolism, most often caused by the deficient activity of the enzyme galactose-1-phosphate-uridyltransferase. Classical galactosemia presents in the neonatal period with life threatening illness after galactose is introduced in the diet. Symptoms and signs include poor feeding, vomiting, and diarrhea, weight loss, jaundice, hypotension, cataracts, hepatosplenomegaly, hepatocellular insufficiency, and encephalopathy. Since 1975 the testing for galactosemia is part of the neonatal screening program in Hungary. Affected newborns are recognized in the first days of their life, and special diet is introduced immediately. The therapy of galactosemia is the lactose-free and galactose-poor diet for life. As a result of the nationwide newborn screening and the lifelong medical therapy, early treatment with galactosemia can achieve a normal life without serious complications.

The death of several black bears at the black bear breeding base in Yunnan Pingbian Daweishan is a matter of concern. Multiple black bears exhibited decreased appetite or unusual waste, and some were soporific or suffered from vomiting and anhelation. In order to ascertain the cause of death, 16S rDNA gene sequencing and phylogenetic analysis was performed on bacteria isolated from tissue samples obtained from dead bears. The biochemical characteristics of the isolated bacteria were subsequently analyzed using different biochemical test systems. The bacteria can decompose glucose, but it cannot produce gas. The fermentation study of sucrose, lactose, trehalose, glycerol and mannitol yielded positive results; while it was unable to decompose urea or ODC (ornithine decarboxylase). Basic Local Alignment Search Tool (BLAST) analysis of a ~1500-bp DNA product amplified from the 16S rDNA of the bacterial isolate revealed that Enterococcus faecium from black bears is highly similar to other E. faecium isolates in the National Center for Biotechnology Information (NCBI) database, and the highest sequence similarity (99%) was with the reference strain. In addition, mice infected with the E. faecium isolate succumbed to severe damage to the lungs, liver, spleen, myocardium, and kidney tissues. In summary, the isolated E. faecium from dead black bears induced pathological changes in mice.
