The Effect of Synbiotic Supplementation on Growth Parameters in Mild to Moderate FTT Children Aged 2-5 Years.

Synbiotic (probiotic bacteria and prebiotic) has beneficial effects on the gastrointestinal tract. This study was designed to investigate the effect of synbiotic supplementation on the growth of mild to moderate failure to thrive (FTT) children. A randomized, triple-blind, placebo-controlled trial was conducted involving 80 children aged 2-5 years with mild to moderate FTT, who were assigned at random to receive synbiotic supplementation (109 colony-forming units) or placebo for 30 days. The weights, height, and BMI were recorded in a structured diary, and the questionnaires were completed to monitor the numbers of infection episodes, gastrointestinal problems, admission to hospital, and appetite improvement during the study. Sixty-nine children completed the study. There were no differences in the demographic characteristic between the two groups. The mean weight was similar at baseline. After 30 days of intervention, the mean weight of the participants in the synbiotic group increased significantly than those in the placebo group (600 ± 37 vs. 74 ± 32 g/month P 0.000). BMI changes in synbiotic and placebo group were 0.44 and 0.07 kg/m2, and that the differences among the two groups were significant.(P 0.045) Furthermore, the height increment in synbiotic and placebo group was 0.41 and 0.37 cm respectively with no significant difference (P 0.761). Administration of 30-day synbiotic supplementation may significantly improve weight and BMI in Iranian children with mild to moderate FTT, but there is no effect on the height in this study. Further studies should be designed to found out the effect of synbiotic on growth parameters in undernourished and well-nourished children.

Bony manifestation of rickets in a sunny city - a case report from Yazd, Iran.

Rickets is disease that occurs in growing bones in which defective mineralization occurs in both the bone and the cartilage of the epiphyseal growth plate, resulting in the retardation of growth and skeletal deformities. Rickets is more common in areas with less sunlight. However, this case report presents a case of the bony manifestation of rickets with the intake of vitamin D supplements in Yazd, a city in central Iran that has sunshine almost every day. A patient was referred to an out-patient general pediatric clinic for deformities of the legs and growth disturbance, with his height far below the normal range. The changes that were most evident in his X-rays were the bowing of the long bones of the legs and forearms and the cupping of the wrist metaphyseal region. In summary, we present a patient with bony manifestation of rickets despite living in a sunny area and taking vitamin D supplements. Thus, it is important to remember that rickets is still a common disease among children in Iran. More studies of this issue should be conducted, including the identification of abnormal cases and rescheduling vitamin D supplementation programs.

Unusual presentation of a perforated appendicitis in a four-year-old girl - a case report from Yazd, Iran.

Difficulties in the early diagnosis of appendicitis, particularly in children, often lead to complications, such as perforation of the appendix, within 36 hours of the onset of symptoms. A four-year-old girl presented to the Emergency Department at Shohadaye Kargar Hospital in Yazd (a city in central Iran) in February 2013 with a history of chronic abdominal pain that began 20 days before admission. Her physical examination revealed a low-grade fever, conjunctivitis, dysuria with malodorous urine, and a mass in right, lower quadrant without localized tenderness in that area. Intestinal intussusception was suggested as the most likely diagnosis, and a laparotomy was performed. The appendix was perforated and an appendicular abscess had caused intestinal obstruction. The rarity of this case, with its unusual presentation and findings, which included unexplained chronic pain, necessitated an immediate operation that revealed the acute presentation of a mechanical obstruction of the intestine. Appendicitis must be kept in the differential diagnosis of any child who presents with chronic abdominal pain. In conclusion, chronic abdominal pain in children is not always of functional origin, and discerning the correct diagnosis can be very challenging. Therefore, clinicians should think broadly since multi-disciplinary input may be inevitable.

Comparison of classic sweat test and crystallization test in diagnosis of cystic fibrosis.

OBJECTIVE: Sweat chloride measurement is considered a standard diagnostic tool for cystic fibrosis (CF). This study was performed to compare sweat chloride values obtained by quantitative pilocarpine iontophoresis (classic test) with sweat crystallization detected by direct observation of a drop of perspiration under light microscopy in patients with and without CF. METHODS: The tests using both techniques were performed simultaneously in patients with and without CF. Cutoff values of ≥60 mmol/L of chloride concentration for the classic sweat test was considered for diagnosis of CF. In crystallization method, observation of typical dendritic forms of salt crystals under light microscopy was interpreted positive. FINDINGS: Sixty patients suspected to CF (31 males and 29 females) with age range of 9 months to 2 years underwent the sweat test using both techniques. Median sweat chloride values was 26.13+10.85 in group with negative and 72.76+12.78 mmol/L in group with positive sweat test, respectively. All the patients who had positive sweat test in classic method showed typical dendritic forms of salt crystal in sweat crystallization test, which provided the test with 100% sensitivity (95%CI: 93.1-100). Only one of the 31 subjects with negative results for classic sweat test had positive result for crystallization sweat test, which provided the test with 96.7% specificity (95%CI: 92.9-100). Time spent to perform the crystallization test was significantly shorter than the classic method whereas its cost was also lower than the second method. CONCLUSION: There was a good correspondence between two studied methods of sweat test. These results suggested the sweat crystallization test as an alternative test for detecting CF disease with high sensitivity and specificity.

Prevalence of occult celiac disease in healthy Iranian school age children.

BACKGROUND:   Several studies have shown the prevalence of celiac disease (CD) to be around 1% in Iran, which is similar to the worldwide prevalence. There is scant information on occult CD in apparently healthy school age children. This study, as the first such study in Iran, aims to determine the prevalence of occult CD in healthy Iranian school age children. METHODS: In this cross-sectional study, we screened healthy school age children for CD by serum IgA and IgA anti-tissue transglutaminase antibody (tTG) levels. Measurement of these antibodies was by enzyme linked immunosorbent assay. A recheck of positive tTG tests was performed and patients who tested positive underwent endoscopic duodenal biopsies. The biopsy samples were scored according to the Marsh classification by an experienced pathologist. RESULTS: A total of 634 children (314 males, 320 females; mean age: 12.8 years) were included in the study. All children and/or their parents completed a questionnaire and children underwent an initial physical examination to determine study eligibility. Positive serum tTG was noted in 3 (0.5%; 2 females) out of 634 patients. Duodenal biopsies were consistent with CD in these 3 subjects. The mean age of patients with CD was 14.3 years (range: 12-17 years). The female to male ratio was 2:1. These cases had no signs and symptoms, but a gluten-free diet was recommended according to pathologic changes in their small bowels and results of the tTG test. CONCLUSION: The prevalence of occult CD in these children is 0.5%, which is half of the prevalence of CD in Iranian adults. The anti-tTG concentration at initial serological CD screening is highly informative in determining occult cases of CD. The question is whether all non-symptomatic cases should be treated with a gluten-free diet or not.

Prevalence of celiac disease in Iranian children with recurrent abdominal pain referred to a pediatric referral center.

OBJECTIVE: Clinical features of Iranian children with celiac disease (CD) are still unknown and there is scant information about atypical presentation of celiac disease from Iran. The aim of this study was to determine prevalence of CD in Iranian children presenting with functional abdominal pain (FAP). METHODS: In this cross-sectional study, 301 children affected by FAP were screened for CD by anti-tissue transglutaminase antibody (tTG IgA). IgA antibody was also measured to exclude IgA deficiency. The antibodies were measured by enzyme linked immunosorbent assay. Diagnosis of CD was confirmed by duodenal biopsy that was scored according to the Marsh classification in cases with abnormal titer of tTG antibody. FINDINGS: A total of 301 children (138 males, 163 females) with FAP were studied. Endoscopic duodenal biopsy was taken for patients with positive and borderline tTG test. Two out of 301 cases were IgA deficient and celiac disease was suspected for one of them based on histological findings. Four out of 299 patients with normal IgA had abnormal tTG titer; intermediate ranges (16-23 U/ml) were detected in 1 and positive ranges (≥24 U/ml) in 3 cases. CD was suggested in all patients with abnormal titer of tTG (1.33%) based on histological findings. CONCLUSION: The prevalence of celiac disease in children with FAP is estimated 1.3% (nearly 2 times higher than in normal population) in Iran.

A case of lipoid congenital adrenal hyperplasia presenting with cholestasis.

BACKGROUND: Lipoid congenital adrenal hyperplasia, is the rarest and usually the most severe form of adrenal steroidogenic defect,which may presents as infantile cholestasis. CASE PRESENTATION: Here we present a 45 days old infant who came to our attention with cholestasis and severe intractable vomiting and electrolyte disturbances. Evaluation resulted in diagnosis of congenital adrenal hyperplasia. Hydrocortisone and flodrocortisone improved the symptoms including jaundice and vomiting. Hyponatremia and hyperkalemia also resolved with above mentioned treatment. CONCLUSION: Congenital adrenal hyperplasia as one of the causes of neonatal cholestasis should be kept in mind, whenever there are also electrolytes abnormalities.

Familial achalasia, a case report.

BACKGROUND: Although achalasia is a relatively rare disease in pediatric age group, it must be considered for differential diagnosis of esophageal disorders in children with positive family history even in the absence of typical clinical manifestations. CASE PRESENTATION: A 5-month old boy was hospitalized for cough and mild respiratory distress. Because of positive history of achalasia in his mother, achalasia was detected in esophgagography. Pneumatic dilation through endoscopy was successful. A 12-month follow-up revealed no problem. CONCLUSION: Achalasia must be considered for differential diagnosis in children with positive family history of achalasia even in the absence of typical clinical manifestations. An autosomal recessive mode of inheritance is probable. We suggest further researches and genetic studies to establish the pattern of inheritance.

Coincidence of Niemann-Pick Disease and beta-Thalassemia; a Case Report.

BACKGROUND: Niemann-Pick disease and ß-thalassemia are distinct conditions with specific clinical and morphological manifestations. ß-thalassemia is the most common inherited blood disorder in Iran whereas Niemann-Pick disease, a lysosomal storage disorder, is rarely found in this country. CASE PRESENTATION: This 5-month old girl, a known case of ß-thalassemia major was hospitalized for failure to thrive and hepathosplenomegaly. Because of unusual splenomegaly and liver enzymes disturbance that was not compatible with the first diagnosis, further evaluation revealed cherry red spot and high lipid profile suggestive of lysosomal storage disease. Foamy cells in the bone marrow and low activity of the specific enzyme led to the diagnosis of Niemann-Pick disease. CONCLUSION: This unique case illustrates the importance of looking for a second pathological condition in a patient whose clinical profile does not support the first diagnosis in its entirety.
