摘要
Tracheobronchopathia osteoplastica (TO) is a rare benign disease in which the anterior inner wall of the tracheobronchus changes because of abnormal chondrogenesis or ossification, while the posterior wall of the trachea is spared. The etiology is not clearly understood, but may relate with chronic infection, inflammation, and trauma. In some case studies, it has also been reported to be accompanied by other chronic diseases such as atrophic rhinitis and amyloidosis. However, Coexistence of TO and tuberculosis has rarely been reported, and has never been reported in Korea. Here, we report a case of a 70-year-old male patient who complained of hemoptysis and whose case was diagnosed as TO and pulmonary tuberculosis through bronchoscopy with bronchial washing and biopsy.

Non-alcoholic fatty liver disease (NAFLD) may be one of the important causes of cryptogenic hepatocellular carcinoma (HCC). NAFLD-related HCCs (NAFLD-HCCs) have the following clinical features: high body mass index, deranged lipid profiles, diabetes mellitus, hypertension, and metabolic syndrome. Among them, obesity, diabetes mellitus, and high Fe contents in the liver are risk factors of developing HCC in patients with NAFLD. Inflammatory cytokines, adipokines, insulin like growth factor-I, and lipotoxicity are intermingled and may cross react with each other to develop HCC. Because there is no guideline for early detection of HCC in patients with NAFLD, NAFLD-HCCs tend to be greater in size and in advanced stages when detected compared with hepatitis virus-related HCCs. Therefore, there is an urgent need of a surveillance program for the early detection of HCC. Treatment of NAFLD-HCCs is not different from other causes-related HCCs. However, patients with NAFLD-HCCs have cardiovascular disease and other metabolic problems, which may complicate treatment.

Herein, we report a rare case of hemolytic anemia with reticulocytopenia following intravenous immunoglobulin therapy in a young infant treated for Kawasaki disease. A 2-month-old boy presented with fever lasting 3 days, conjunctival injection, strawberry tongue, erythematous edema of the hands, and macular rash, symptoms and signs suggestive of incomplete Kawasaki disease. His fever resolved 8 days after treatment with aspirin and high dose infusion of intravenous immunoglobulin. The hemoglobin and hematocrit decreased from 9.7 g/dL and 27.1% to 7.4 g/dL and 21.3%, respectively. The patient had normocytic hypochromic anemia with anisocytosis, poikilocytosis, immature neutrophils, and nucleated red blood cells. The direct antiglobulin test result was positive, and the reticulocyte count was 1.39%. The patient had an uneventful recovery. However, reticulocytopenia persisted 1 month after discharge.

PURPOSE: Wheezing following viral lower respiratory tract infections (LRTIs) in children <2 years of age is an important risk factor for the development of asthma later in life; however, not all children with viral LRTIs develop wheezing. This study investigated risk factors for the development of wheezing during viral LRTIs requiring hospitalization. METHODS: The study included 142 children <2 years of age hospitalized for LRTIs with at least one virus identified as the cause and classified them into children diagnosed with LRTIs with wheezing (n=70) and those diagnosed with LRTIs without wheezing (n=72). RESULTS: There were no significant differences in the viruses detected between the two groups. Multivariate logistic regression analysis showed that, after adjusting for potentially confounding variables including sex and age, the development of wheezing was strongly associated with parental history of allergic diseases (adjusted odds ratio [aOR], 20.19; 95% confidence interval [CI], 3.22-126.48), past history of allergic diseases (aOR, 13.95; 95% CI, 1.34-145.06), past history of hospitalization for respiratory illnesses (aOR, 21.36; 95% CI, 3.77-120.88), exposure to secondhand smoke at home (aOR, 14.45; 95% CI, 4.74-44.07), and total eosinophil count (aOR, 1.01; 95% CI, 1.01-1.02). CONCLUSION: Past and parental history of allergic diseases, past history of hospitalization for respiratory illnesses, exposure to secondhand smoke at home, and total eosinophil count were closely associated with the development of wheezing in children <2 years of age who required hospitalization for viral LRTIs. Clinicians should take these factors into consideration when treating, counseling, and monitoring young children admitted for viral LRTIs.

PURPOSE: We assessed the relationships between iron and vitamin D statuses in breastfed infants and their mothers and evaluated the determinants of iron and vitamin D deficiencies in breastfed infants. METHODS: Seventy breastfed infants aged 4-24 months and their mothers participated in this study from February 2012 to May 2013. Complete blood counts, total iron binding capacity, and levels of C-reactive protein, iron, ferritin, calcium, phosphate, alkaline phosphatase, and 25-hydroxyvitamin D (25(OH)D) in infants and their mothers were measured. RESULTS: A history of maternal prepregnancy anemia was associated with lower ferritin and 25(OH)D levels in both infants and their mothers. The 25(OH)D level of infants correlated with maternal 25(OH) D levels. The independent risk factors for iron deficiency in breastfed infants were the duration of breastfeeding (odds ratio [OR], 6.54; 95% confidence interval [CI], 1.09-39.2; P=0.04) and infant body weight (OR, 2.65; 95% CI, 1.07-6.56; P=0.04). The determinants for vitamin D deficiency were the infant's age (OR, 0.15; 95% CI, 0.02-0.97; P=0.046) and maternal 25(OH)D level (OR, 0.74; 95% CI, 0.59-0.92; P=0.01). CONCLUSION: A maternal history of prepregnancy anemia requiring iron therapy was associated with lower current ferritin and 25(OH)D levels in both infants and their mothers. Therefore, physicians should monitor not only iron but also vitamin D levels in infants who are breastfed by mothers who had prepregnancy anemia.

PURPOSE: The clinical interpretation of children sensitized to allergens is challenging, particularly in children with food allergies. We aimed to examine clinical differences between children with monosensitization and those with polysensitization to common food allergens and to determine risk factors for polysensitization in young children <10 years of age with immediate-type food allergies. METHODS: The study included children <10 years of age with signs and symptoms indicative of immediate-type food allergies. Serum total IgE level was measured, and ImmunoCAP analysis for food allergens was performed. RESULTS: The mean age of the study subjects was 1.6+/-1.6 years (75 boys and 51 girls). Thirty-eight children (30.2%) were monosensitized and 88 children (69.8%) were polysensitized. Multivariate logistic regression analysis showed that the development of polysensitization to common food allergens was positively associated with a parental history of allergic rhinitis (adjusted odds ratio [aOR], 6.28; 95% confidence interval [CI], 1.78-22.13; P=0.004), season of birth (summer/fall) (aOR, 3.10; 95% CI, 1.10-8.79; P=0.033), and exclusive breastfeeding in the first 6 months of age (aOR, 3.51; 95% CI, 1.20-10.25; P=0.022). CONCLUSION: We found significant clinical differences between children with monosensitization and those with polysensitization to common food allergens and identified risk factors for the development of polysensitization in young children with immediate-type food allergies. Clinicians should consider these clinical risk factors when evaluating, counseling, treating, and monitoring young children with food allergies.

PURPOSE: Population studies have reported that sensitization to inhalant allergens is rare in young children; however, most subjects in those studies had little or no symptoms or signs highly suggestive of allergic diseases. The aim of the present study was to assess the prevalence of sensitization to inhalant allergens in young children with symptoms and/or signs of allergic disease. METHODS: We analyzed the results of all specific IgE tests performed at our hospital laboratory in children younger than 6 years presenting with symptoms and/or signs highly suggestive of allergic diseases between 2008 and 2013. Specific IgE tests for Dermatophagoides pteronyssinus, Dermatophagoides farinae, Alternaria alternata, German cockroach, cat dander, egg white or egg yolk, milk, peanut, and soybean were performed on 295 children; a specific IgE concentration > or =0.35 or > or =0.2 IU/mL was considered positive. We also compared allergen sensitization rates using the two cutoff values. RESULTS: One hundred eighty-one children (61.4%) were positive to at least 1 allergen tested and 53 children (18.9%) were positive to at least 1 inhalant allergen when a specific IgE concentration > or =0.35 IU/mL was considered positive. The children were more likely to have asthma or allergic rhinitis when they were sensitized to any inhalant allergen, particularly house dust mites. The prevalence of sensitization to inhalant allergens increased with age (P<0.001). There was no significant difference in the prevalence of polysensitization among different age groups, but sensitization to both inhalant and food allergens significantly increased with age. CONCLUSION: Our results suggest that specific IgE tests to common inhalant allergens, particularly the house dust mites, may be considered when performing blood screening tests for young children presenting with symptoms and/or signs of allergic diseases.

BACKGROUND/AIMS: Pancreatic cancer is fatal with a dismal 6-month median survival from diagnosis. Diabetes mellitus is reported to be present up to 33.3 percent of patients with pancreatic cancer. The reason for the high frequency of diabetes is unknown. We studied the prevalence and duration of diabetes in patients with pancreatic cancer and the relationship between the two diseases. METHODS: A total of 152 patients with pancreatic cancer diagnosed at Yeungnam University Hospital from January 1999 to December 2001 were enrolled in this study. Clinical features, family history, smoking history, and characteristics of the tumor were compared between diabetic and non-diabetic groups. RESULTS: Among 152 patients with pancreatic cancer, 43 patients (28.3%) had diabetes. In diabetic group, mean age of diagnosis was significantly younger than non- diabetic group (62.0 +/- 7.2 vs. 65.0 +/- 8.8, p<0.05). Most of the patients with diabetes had non-insulin dependent diabetes mellitus (NIDDM) and did not have family history. Diabetes was diagnosed within 2 years after the diagnosis of pancreatic cancer in 35 patients (74.3%) of the diabetic group. There were no differences in the location and stage of tumor, chief complaints, presence of weight loss, and body mass index between the two groups. CONCLUSIONS: Diabetes mellitus occurs frequently in patients with pancreatic cancer and does not influence clinical features of pancreatic cancer. Pancreatic cancer should be suspected in patients with recent onset diabetes, especially in patients without family history of diabetes and with type of NIDDM.

The identification of serum HBV DNA is very important for the assessment of the disease activity in persistent infection, for the evaluation of the infectivity of an individuals blood. The dot blot, however, has limited sensitivity and sometimes inconsistent with other serological markers and clinical settings. Using the most important recent advance in molecular biology, the polymerase chain reaction(PCR), specific DNA sequences can be amplified more than a million-fold in a few hours and with this technique the detection of the extreme low level of DNA is possible. This study was to determine sensitivity of the PCR for the detection of serum HBV DNA in comparison with dot blot analysis and to investigate the serum HBV DNA status and clinical significance of PCR in patients with chronic HBsAg positive liver disease. The subjects of this study were 17 patients with asymptomatic HBsAg carriers(9 HBeAg positive patients, 8 anti-HBe positive patients), 91 chronic hepatitis B(50 HBeAg positive patients, 41 anti-HBe positive patients), 57 liver cirrhosis(21 HBeAg positive patients, 36 anti-HBe positive patients), 27 hepatocellular carcinoma(10 HBeAg positive patients, 17 anti-HBe positive patients). The results were summerized as following; The detection rates of HBV DNA by dot blot, PCR were 58.9%, 72.2% in HBeAg positive patients, 34.3%, 53.9% in anti-HBe positive patients. The detection rates of HBV DNA by PCR in HBeAg negative patients were 25.0% in asymptomatic HBsAg carriers, 61.0% in chronic hepatitis B, 52.8% in liver cirrhosis, 52.9% in hepatocellular carcinoma. The positive rate for HBV DNA is a significant difference between HBeAg positive and negative asymptomatic HBsAg carriers, but not significantly difference in other groups. In conclusions, this study confirmed that the PCR is much more sensitive than the dot blot analysis in detecting the HBV DNA in the sera of patients with chronic liver disease. The presence of HBV DNA in the serum was detected by PCR with higher sensitivity and it suggested that active viral replication is still going on in most patients with chronic HBsAg positive liver disease irrespective of HBeAg/anti-HBe status, and PCR may be used as a prognostic factor in asymptomatic HBsAg carriers.

Recently, increased emphasis has been placed on the need for rehabilitation professionals to objectively evaluate a patient's potential for and progress toward a return to normal function. But as medical recovery nears completion, additional questions are commonly asked by physicians regarding work function and ability to return to full active employment. In the past, therapists have attempted to reestablish the work situation using real tools, but these machines were expensive, have space limitations and in some cases, potentially dangerous as well. A Baltimore Therapeutic Equipment(BTE) Work Simulator overcomes these shortcomings. It can be used for isometric and isotonic evaluation and treatment and assisted in providing the information needed to make determinations regarding progress in therapy, return-to-work status and job modifications. We are going to obtain normative isometric, dynamic and endurance of grip strength, key pinch strength and three point pinch strength data using BTE Work Simulator model WS20. We also compare these data between ages and sexs. This study will be helpful in clinical applications of the BTE Work Simulator and providing the more specific job related occupational therapy and developing special vocational rehabilitation program.

Majority of .hepatocellular carcinoma is evolved from a well differentiated cancerous condition such as hypetptastic lesions eg; adenomatous hyperplasia in cirrhotic liver or de no vo carcinogenesis and prolifenation along with dedifferentiation. Adenomatous hyperplasia is may be seen in severe acute hepatic injury, like svhmassive hepatic necrosis, or in chronic liver diseases, particularly liver cirrhosis and it has recently attracted much interest from both clinicians and pathologists because it is regarded as a precursor lesion of hepatocObdar carcinoma. Hepatic. denomatous hyperplasia resembling focal nodular hyperplasia might have developed from localized vascular changes associated with chronic liver disease, pre-existing arterial malformation and early stage of angiogenesis in hepatocarcinogenesis. .fie present a patient who developed hepatocellular carcinoma after hepatic artery ligation.

Pure primary hepatic rhabdomyosarcoma in adult is very uncommon. There have been only five previous case of primary rhabdomyosarcoma of the adult liver. A case of hepatic ihabdomyosarcoma was diagnosed in a 52 year-old female. She was admitted to the hospital due to the epigastric pain and weight loss. A CT scan of the abdomen showed a large hypodense mass with focal calcification occupies most of the both lobes of the liver. The liver biopsy showed massive liver tumor composed entirely of oval shaped cells showing light microscopic and immunohistochemical evidence of rhabdomyoblastic differentiation. We report a case of hepatic rhabdomyosarcoma with review of literature.
