1.Genetic Factors in Bronchial Asthma.
Korean Journal of Medicine 2010;79(4):366-373
Bronchial asthma is a chronic inflammatory disease of the airways in which there isincreased responsiveness to various stimuli, resulting in wheezing, shortness of breath, and coughing. Interactions between environmental and genetic factors may modify both the susceptibility to and severity of the disease. In recent years, much progress has been made in improving our understanding of the genetic basis of bronchial asthma, which has led to the identification of several genetic factors. This review is an update of genetic studies of bronchial asthma and recent findings.

BACKGROUND: Kerationcytes make up the vast majority of cells within the epidermis. Recent attention has focused on the role keratinocytes may play in the induction of T cell mediated inflammatory responses in skin, particularily because keratinocytes, when activated by immunologic stimuli, express MHC class llAg and secrete cytokines. But in experimentally induced lichenoid tissue reaction by interferon-nu, MHC class ll Ag was not essential for the enhanced T cell trafficking. There is growing evidence that keratinocyte intercellular adhesion molecule-1 (ICAM-1) expression is involved in the epidermal trafficking of T lymphocytes. OBJECT: To investigate the kinetics of expression of the HLA-DR and ICAM-1 on cultured human keratinocytes by recombinant-interferon-nu(IFN) and phorbol myristate acetate(PMA), and the influence of the HLA-DR and ICAM-1 and the stimulation of peripheral blood mononuclear leukocytes(PBML). RESULTS: 1. 1 U/ml of IFN can induce HLA-DR and ICAM-1 on keratinocytes. Expression of both antigens were increased in a dose and exporsure time dependent fashion. But expression of HLA-DR was less sensitive to IFN than ICAM-1 2. ICAM-1 induction was more rapid than HLA-DR. Keratinocytes expressed HLA-DR 6hours after IFN treatment amd increased rapidly after 12 hours. 3. HLA-DR positive keratinocytes were decreased more rapidly that ICAM-1 positive kerationcytes. 4. Proliferations of PBML were slightly inhibited when cultured with keratinocytes which were treated or not treated with IFN. But IFN treated keratinocytes stimulated the PBML more than untreated keratinocytes. Proliferaton of PBML by IFN treated keratinocytes were inhibited by anti-ICAM monoclonal antibody 5. PMA treated keratinocytes stimulated the PBML more than untreated keratinocytes. Proliferation of PBML by PMA treated keratinocytes was inhibited by anti-ICAM monoclonal antibodies and anti-LFA-1 monoclonal antibodies. CONCLUSION: These results suggest that keratinocytes can express not only HLA-DR but also ICAMP1 may play a important role in initiating immunologic response. Complete clarification of the function of HLA-DR and ICAM-1 positive keratinocytes requires furthe5r study

7.Genetic studies of allergic disease and their clinical implications.
Korean Journal of Medicine 2009;76(4):416-424
Allergic disease is a complex disorder in which the interaction between environmental and genetic effects may modify both the susceptibility to and severity of the disease. Over the last few years, our understanding of the genetic basis of allergic diseases has improved markedly, which has led to the identification of several chromosome regions and loci showing linkage to allergic disease. As another approach, association studies between candidate gene polymorphisms and allergic diseases have been conducted in many areas and replicated in different ethnic groups. These approaches need to be followed by validation processes to confirm their functional relevance in the pathophysiology of allergic disease. This review updates genetic studies of and recent findings in, allergic disease.

CT has becom increasingly important diagnostic method as the inital examination in the diagnosis of subarachnoid hemorrhage with direct detection of extravasated blood inbasal cistern and cortical sulci. Furthermore, CT provides better and exact visualization of the presence, localization, extent and degree of intracerebral, intraventricular and subdural hemorrhage, infarction, hydrocephalus and rebleeding which may be associated wtih subarachnoid hemorrhage, and also could detect the causative lesions with contrast enhancement inmany cases. The purpose of the paper is to describe the CT findings of subarachonid hemorrhage due to various causes and to evalute the diagnostic accuracy of CT in subarachonoid hemorrhage. Authors analysed a total of 153 cases with subarachnoid hemorrhage confirmed by lumbar puncture at Seoul National University Hospital from March 1979 to April 1981, with special emphasis on CT findings.All of the cases took CT scan and 125 cases of the mangiography. The results are as follows; 1. Most prevalent age group was 4th to 6th decades (78%). The ratio ofmale to female was 1.1:1. 2. Of all 125 with angiography, aneurysm was a major cause (68%). Others were arterio-venous malformation (9.6%), Moya-moya disease(4%) and unknown (18.4%). 3. Of all 153 cases with CT scan,hemorrhage was demonstrated in 98 cases (64.1%); SAH in 72 cases (47.1%), ICH in 65 cases (42.5%), IVH in 34 cases(22.2%) and SDH in 1 case(0.7%). SAH combined with ICH was a major group (34.7%) in SAH. Detecton rate of SAH was68.3% within the first 7 days and 5.8% after 7 days. 4. In aneurysms, SAH was detected in 60 of 85 cases (70.6%);88.1% within the first 7 days and 5.6% after 7 days. Anterior communicating artery was the most common site of theaneurysms(40%), in which detection rate of SAH was 100% within the first 7 days. SAH was combined with ICH in38.3%. 5. On CT, SAH of unilateral Sylvian fissure was pathognomonic for ruptured MCA aneurysm and ICH of corpuscallosum for ACA aneurysm. 6. The detection rate of aneurysm itself on CT was 20%(17/85) and its size was variablefrom 5 to 25mm. 7. Infarction was demonstrated in 9 cases (6%) and there was no significant correlation between infarction and angiospasm, 8. Hydrocephalus was detected in 65% cases(42.5%), and 21 cases (32.3%) were demonstrated within the first 3 days.

The main challenge in pharyngoesophageal reconstruction is the restoration of swallow and speech functions. The aim of this paper is to review the reconstructive options and associated complications for patients with head and neck cancer. A literature review was performed for pharynoesophagus reconstruction after ablative surgery of head and neck cancer for studies published between January 1980 to July 2015 and listed in the PubMed database. Search queries were made using a combination of 'esophagus' and 'free flap', 'microsurgical', or 'free tissue transfer'. The search query resulted in 123 studies, of which 33 studies were full text publications that met inclusion criteria. Further review into the reference of these 33 studies resulted in 15 additional studies to be included. The pharyngoesophagus reconstruction should be individualized for each patient and clinical context. Fasciocutaneous free flap and pedicled flap are effective for partial phayngoesophageal defect. Fasciocutaneous free flap and jejunal free flap are effective for circumferential defect. Pedicled flaps remain a safe option in the context of high surgical risk patients, presence of fistula. Among free flaps, anterolateral thigh free flap and jejunal free flap were associated with superior outcomes, when compared with radial forearm free flap. Speech function is reported to be better for the fasciocutaneous free flap than for the jejunal free flap.
