OBJECTIVE: To investigate the distribution of Ret-He and RBC in thalassemia and the value of combining HbA2 in the detection of thalassemia among patients with microcytic or hypochromic. METHODS: 145 patients with microcytic or hypochromic outpatient or hospitalization in our hospital from May 2018 to December 2019 were selected and were divided into the thalassemia group(68 cases) and the non-thalassemia group (77 cases), and at the same time, the patients were divided into four groups of the non-anemia, mild anemia, moderate anemia and severe anemia group according to the degree of anemia. The Ret-He, RBC, RDW-CV and HbA2 in patients were detected, and the distribution of these parameters were compared, and the joint detection of Ret-He, RBC and HbA2 about its sensitivity, specific and other indicators of auxiliary diagnosis of thalassemia were analyzed. RESULTS: Among patients with microcytic or hypochromic, according to the anemia grade Ret-He gradually decreased from the non-anemia group to the severe anemia group (P<0.05); while RDW-CV was increased gradually from the mild anemia group to the severe anemia group (P<0.05); both RBC and Ret-He were increased in the thalassemia group as compared with the non- thalassemia group (P<0.05); while RDW-CV was decreased in the thalassemia group as compared with the non-thalassemia group (P<0.05); meanwhile Ret-He in the α-thalassemia group was higher than that in the β-thalassemia group. ROC curve analysis showed that combined with HbA2, the specificity was 93.51%, the sensitivity was 66.18%, the positive predictive value was 90% and the negative predictive value was 75.189% when Ret-He was truncated with 19.25 pg and RBC was truncated with 4.95×10 CONCLUSION Among patients with microcytic or hypochromic, the distribution of RBC, Ret-He and RDW-CV was different in the thalassemia group and the non-thalassemia group, and was also affected by the degree of anemia. Combined Ret-He and RBC could improve the diagnostic specificity for thalassemia, which were screened by HbA2 in patients with microcytic or hypochromic.

We report a rare case of Meckel's diverticulum in a boy who initially presented with chronic iron deficiency anemia (IDA) without any history of gastrointestinal (GI) bleeding at 8 years-old. Isolated small bowel Crohn's disease was suspected based on findings of small bowel ulcers on capsule endoscopy. At four years from initial presentation, he developed massive GI bleeding. Abdominal computed tomographic angiography and small bowel series revealed findings suggestive of Meckel's diverticulum. Meckel's diverticulum should be suspected in children with unexplained chronic IDA even in the absence of prominent GI bleeding and negative findings on repetitive Meckel's scans. Moreover, Meckel's diverticulum should be included in the differential diagnosis of isolated small bowel Crohn's disease when the disease is limited to a short segment of the distal small bowel, as ulcers and inflammation may result as a consequence of acid secreted from adjacent heterotopic gastric mucosa constituting the Meckel's diverticulum.

Hookworm infections are widely prevalent in tropical and subtropical areas, especially in low income regions. In the body, hookworms parasitize the proximal small intestine, leading to chronic intestinal hemorrhage and iron deficiency anemia. Occasionally, hookworms can cause overt gastrointestinal bleeding, but this is often ignored in heavily burdened individuals from endemic infectious areas. A total of 424 patients with overt obscure gastrointestinal bleeding were diagnosed by numerous blood tests or stool examinations as well as esophagogastroduodenoscopy, colonoscopy, capsule endoscopy or double-balloon enteroscopy. All of the patients lived in hookworm endemic areas and were not screened for hookworm infection using sensitive tests before the final diagnosis. The patients recovered after albendazole treatment, blood transfusion, and iron replacement, and none of the patients experienced recurrent bleeding in the follow-up. All the 31 patients were diagnosed with hookworm infections without other concomitant bleeding lesions, a rate of 7.3% (31/424). Seventeen out of 227 patients were diagnosed with hookworm infections in the capsule endoscopy (CE), and 14 out of 197 patients were diagnosed with hookworm infections in the double balloon enteroscopy (DBE). Hookworm infections can cause overt gastrointestinal bleeding and should be screened in patients with overt obscure gastrointestinal bleeding (OGIB) in endemic infectious areas with sensitive methods. Specifically, the examination of stool specimens is clinically warranted for most patients, and the proper examination for stool eggs relies on staff's communication.

PURPOSE: Celiac disease, an autoimmune enteropathy triggered by exposure to gluten, is not uncommon in South Jordan. However, its prevalence is underestimated due to lack of physician awareness of the diversity of disease presentation. The clinical spectrum includes classic gastrointestinal manifestations, as well as rickets, iron-deficiency anemia, short stature, elevated liver enzymes, and edema. Our goal was to evaluate celiac disease presentation in clinically diagnosed children. METHODS: Retrospective study included all children diagnosed with celiac disease between September 2009 and September 2015. Hospital charts were reviewed. Demographic data, clinical characteristics, and follow-up were recorded. RESULTS: Thirty-five children were diagnosed with celiac disease during the study period. Mean age±standard deviation was 6.7±3.8 years (range, 2.0–14 years). There were 17 (48.6%) female patients. The average duration between onset of symptoms and diagnosis was 16.3±18.7 months. Fifteen (42.9%) patients presented with classic malabsorption symptoms, whereas 7 (20.0%) patients presented with short stature. Positive tissue transglutaminase antibodies (tTg)-immunoglobulin A (IgA) was seen in 34 (97.1%) patients. The one patient with negative tTg-IgA had IgA deficiency. Although tTG-IgA values were not available for objective documentation of compliance, clinical data (resolution of presenting abnormalities and growth improvement) assured acceptable compliance in 22 (62.9%) patients. CONCLUSION: CD in children may present with diverse picture. Although of the small number, the non-classical presentations are not uncommon in our rural community. Gluten-free diet is the main strategy for treatment and associated with usually correction of laboratory abnormalities and improvement of growth.

Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) are a group of malignant tumors with varying degrees of neuroectodermal differentiation. Although it may develop in any organs, ES/PNET originating from small intestine is exceedingly rare. We experienced a 9-year-old girl presenting with abdominal pain, melena, and iron deficiency anemia. Imaging work-up showed multiple masses in the small bowel and omentum with disseminated peritoneal seeding nodules, indicating lymphoma as the most likely diagnosis. Pathological reports from explorative diagnostic laparoscopic biopsy showed tumors comprising small round cells with CD99 expression and EWS-FLI1 translocation leading to the diagnosis of ES/PNET. Tumor burden decreased gradually during five consecutive cycles of systemic chemotherapy. The patient received segmental resection of jejunum, followed by adjuvant chemotherapy. This is the first pediatric case of ES/PNET found in small intestine in Korea.

Helicobacter pylori infection is acquired mainly during childhood and causes various diseases such as gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphoma, and iron deficiency anemia. Although H. pylori infection in children differs from adults in many ways, this is often overlooked in clinical practice. Unlike adults, nodular gastritis may be a pathognomonic endoscopic finding of childhood H. pylori infection. Histopathological findings of gastric tissues are also different in children due to predominance of lymphocytes and plasma cells and the formation of gastric MALT. Although endoscopy is recommended for the initial diagnosis of H. pylori infection, several non-invasive diagnostic tests such as the urea breath test (UBT) and the H. pylori stool antigen test (HpSA) are available and well validated even in children. According to recent data, both the ¹³C-UBT and HpSA using enzyme-linked immunosorbent assay are reliable non-invasive tests to determine H. pylori status after eradication therapy, although children younger than 6 years are known to have high false positives. When invasive or noninvasive tests are applied to children to detect H. pylori infection, it should be noted that there are differences between children and adults in diagnosing H. pylori infection.

Iron supplements such as ferrous sulfate tablets are usually used to treat iron-deficiency anemia in some elderly patients with primary neurologic disorders or decreased gag reflexes due to stroke, senile dementia, or parkinsonism. While the aspiration of ferrous sulfate is rarely reported, it is a potentially life-threatening condition that can lead to airway necrosis and bronchial stenosis. A detailed history and high suspicion of aspiration are required to avoid delays in diagnosis and treatment. The diagnosis can be confirmed by bronchoscopic examination and a tissue biopsy. Early removal of the aspirated tablet prevents acute complications, such as bronchial necrosis, hemoptysis, and lobar consolidation. Tablet removal is also necessary to prevent late bronchial stenosis. We presented the first case in Korea of a ferrous sulfate tablet aspiration that induced severe endobronchial inflammation.
