PURPOSE: We investigated the clinical manifestations of combination therapy with photodynamic therapy (PDT) and intravitreal bevacizumab in idiopathic macular telangiectasia type I patients. METHODS: The present study included 7 patients who visited our clinic from May 2008 to February 2011 complaining of decreasing visual acuity and diagnosed as idiopathic macular telangiectasia type I including visible aneurysms at juxtafoveal area and telangiectatic vessels leakage based on fluorescein angiography. Additionally, all patients were treated with combination therapy with PDT and intravitreal bevacizumab. RESULTS: Visual acuity improved from 0.48 ± 0.14 (log MAR) to 0.18 ± 0.17 (log MAR) after the combination therapy, however, there was no change in intraocular pressure between before (17.9 ± 3.1) and after (16.8 ± 2.3) therapy. After combination therapy, fluorescein angiography showed decreased leakage of telangiectatic vessels and optical coherence tomography showed only minimal intraretinal edema. Central subfield macular thickness decreased from 301.9 ± 50.7 μm to 193.6 ± 58.8 μm after the combination therapy. CONCLUSIONS: Combination therapy with intravitreal bevacizumab injection and PDT in patients with idiopathic macular telangiectasia type I can result in a rapid decrease of macular edema, which can lead to rapid visual recovery.

PURPOSE: The prevalence of developmental delay is 5-10% of the total pediatric population and early diagnosis and proper intervention are essential but a challenge for clinicians. We performed this study for several purposes. First is to know the distribution & characteristics of developmental disorders in Korea. Second is to identify all possible causes of these disorders through a multidisciplinary diagnostic approach, and thus to find out the clinical variables that are helpful in finding the etiology. And finally to develop a useful protocol that eliminates the cost of unnecessary tests and raises the diagnostic rate of the cause. METHODS: 518 patients(M 349, F 169) were studied who visited Ilsan Hospital Developmental Disorder Clinic(DDC) for the evaluation of developmental delay from April 2001 to Jan 2005. RESULTS: The mean age was 51.5+/-32.9 months, ranging from 2 months to 16.0 years of age with a majority of the preschool children(<6 yr)(79.3%). Phenomenological diagnosis consisted of 133 cases of mental retardation, 122 cases of autistic disorders, 101 cases of delayed language disorders, 27 cases of cerebral palsies, and 91 cases labeled as simple developmental delay requiring follow up due to age less than 2 years of age. Etiologic diagnosis was obtained in 119 cases(22.9%) out the 518 cases of developmental delays. 37 cases of chromosomal anomalies, 23 cases of Periventricular leukomalacia and hypoxic ischemic encephalopathy, 21 cases of syndromes, 7 cases of malformation of cortical development, 4 cases of myopathies, 4 cases of neuropathies, and 4 cases of cerebral infarctions were found. Among the clinical variables, low birth weight, facial dysmorphism, hypotonia, focal neurologic signs, and abnormalities in MRI, chromosome, EEG and EMG studies contributed to the yields of etiologic diagnosis significantly. CONCLUSION: Possible etiology was determined in about 23% of the subjects. The most important part of the assessment for the identification of etiology is thorough history taking, physical and neurologic examination. Neuroimaging study is useful in case of micro or macrocephaly, focal neurologic signs. Genetic studies increasingly produce a yield, when there is family history of inherited disorder and there are dysmorphic features. Routine metabolic screening test has limited utility. Development of a useful screening protocol adequate for Korean situation is required.

PURPOSE: Clinically, acute respiratory distress syndrome (ARDS) occurs within 72 hours after acute exposure of risk factors. Because of its high fatality rate once ARDS progresses, early detection and management are essential to reduce the mortality rate. Accordingly, studies on early changes of ARDS were started, and serum ferritin, as well the as injury severity score (ISS), which has been addressed in previous studies, thought to be an early predictive indicator for ARDS METHODS: From March 2003 to March 2005, we investigated 50 trauma patients who were admitted to the intensive care unit in Dongguk University Medical Center, Gyeongju. The patients were characterized according to age, sex, ISS, onset of ARDS, time onset of ARDS, serum ferritin level (posttraumatic 1st & 2nd day), amount of transfused blood, and death. Abdominal computed topography was performed as an early diagnostic tool to evaluate the onset of ARDS according to its diagnostic criteria. The serum ferritin was measured by using a VIDAS(R) Ferritin (bioMeriux, Marcy-1' Etoile, France) kit with an enzyme-linked fluorescent assay method. For statistical analysis, Windows SPSS 13.0 and MedCalc were used to confirm the probability of obtaining a predictive measure from the receiver operating characteristics (ROC) curve. RESULTS: The ISS varied from 14 to 66 (mean: 33.8) whereas the onset of ARDS could be predicted with the score above 30 (sensitivity: 90.0%, specificity: 60.0%, p<0.05). On the posttraumatic 1st day, the serum ferritin levels were measured to be from 31 mg/dL to 1,200 mg/dL (mean: 456 mg/dL), and the onset of ARDS could be predicted when the value was over 340 mg/dL (sensitivity: 80.0%, specificity: 65.0%, p<0.05). On the posttraumatic 2nd day , the serum ferritin levels were measured to be from 73 mg/dL to 1,200 mg/dL (mean: 404 mg/dL), and the onset of ARDS could be predicted when the value was over 627 mg/dL (sensitivity: 60.0%, specificity: 92.5%, p<0.05). The serum ferritin levels and the ISS were significantly higher on the posttraumatic 1st and 2nd day in the ARDS group, suggesting that they are suitable indices predicting the onset of ARDS, however relationship between the serum ferritin levels and the ISS was not statistically significant. CONCLUSION: In this study, we discovered increasing serum ferritin levels in multiple- trauma patients on the posttraumatic 1st & 2nd day and concluded that both the serum ferritin level and the ISS were good predictors of ARDS. Although they do not show statistically significant relationship to each other, they can be used as independent predictive measures for ARDS. Since ARDS causes high mortality, further studies, including the types of surgery and the methods of anesthesia on a large number of patients are essential to predict the chance of ARDS earlier and to reduce the incidence of death.

Tumor necrosis factor alpha (TNF-alpha) inhibitors are used widely to treat patients with active rheumatoid arthritis and ankylosing spondylitis (AS). Although various cutaneous reactions can occur as side effects of TNF-alpha inhibitors, systemic vasculitis requiring withdrawal of the agent and immunosuppressive drugs is rare. A 59-year-old male with AS who had been treated with infliximab for 60 months visited us with complaints of palpable purpura on both legs and severe abdominal pain. Abdominal computed tomography showed diffuse wall thickening of the proximal jejunum and ileum and a skin biopsy revealed leukocytoclastic vasculitis. The patient was diagnosed with Henoch-Schonlein purpura (HSP). Infliximab was discontinued and systemic steroid therapy at 0.5 mg/kg resulted in prompt resolution of the HSP. Here, we report the first case of HSP in a patient with AS after infliximab treatment.

Vocal cord paralysis is a comlex disorder which may result from numerous causes. It is often associated with trauma, disease in adjacent tissue, or a generalized neuroligical disorder. Laryngeal EMG is a useful technique for vocal cord paralysis. However it has not been used due to the uncertainties of normal human vocal cord physiology and the technical difficulties in performing these studies. We investigated the pathophysiology of vocal cord paralysis with laryngeal electromyography(LEMG). We studied 20 patients with idiopathic vocal cord paralysis. 6 patients were denervated in the cricothyroid(CT) and 6 patients in the thyroarytenoid(TA), and 3 patients in both CT and TA muscles. These indicated superior laryngeal neuropathy, recurrent laryngeal neuropathy, and proximal laryngeal or vagus neuropathy, respectively. LEMG proved to be a safe and effective procedure in the diagnosis of laryngeal neuropathy, and make it possible to use electromyography as a routine procedure in diagnosis laryngeal paralysis.

BACKGROUND: Sorbitol fermenting Escherichia coli O157 were reported. And E. coli O157:H7 produce various Shiga toxin (Stx) such as Stx1, Stx2, or variants of Stx2. In this study, we tried to establish laboratory methods that detect E. coli O157:H7 quickly and precisely by analyzing sensitivity of colony hybridization test and PCR technique. METHODS: Stx1-producing E. coli ATCC 43890, Stx2-producing E. coli ATCC 43889, and Stx2vha- producing E. coli ATCC 51435 were tested. Three strains of E. coli were diluted with 0.1 g of diarrheal stools from 107 CFU to 101 CFU respectively. The stool samples were incubated overnight in MacConkey agar plates. A mean of 63 colonies were hybridized by stx1- and stx2-specific oligonucleotide probes. PCR for stx1 gene and stx2 gene was done after overnight- incubation of stool samples in the LB broth with vancomycin (6 ug/mL). Positive colonies by colony hybridization were confirmed by PCR for stx1 gene and stx2 gene. RESULTS: Colony hybridization test could detect Stx1-producing E. coli at 103 CFU per 0.1 g of stool, Stx2-producing E. coli at 105 CFU per 0.1 g of stool, and Stx2vha-producing E. coli at 104 CFU per 0.1 g of stool. PCR technique after enrichment in LB broth with vancomycin (6 ug/mL) could detect stx1-, stx2-, and stx2vha-containing E. coli at 10 CFU per 0.1 g of stool respectively. CONCLUSOIN: A combination of colony hybridization and PCR after enrichment in broth with vancomycin (6 ug/mL) is useful for the rapid and precise diagnosis of infections of Shiga toxin-producing E. coli O157:H7.

We present a case of recurrent left atrial myxoma which occurred 7 years and 10 months after initial operation despite resection of originaltumor and adjacent atrial septum. This is the first case report of recurrence in Korea. Among the possible causes of recurrence, regrowth from pretumorous focus seems to be the most suggesting one in this case. Histopathologic findings of recurrent myxoma showed increased cellularity with active proliferation and nuclear hyperchromasia. These findings, together with the rapidity of regrowth, suggest that recurrent myxoma may have 'wilder' behavior. Prolonged postoperative observation is important, even if ample resection was done at the initial operation including atrial septum.

A dieulafoy lesion, which is an unusual cause of gastrointestinal bleeding that can be fatal in children. Dieulafoy lesions are characterized by an abnormally large eroded submucosal artery that is commonly located in the lesser curvature of the proximal stomach. In most cases, permanent hemostasis is achieved by endoscopic epinephrine injection, however, some patients require other endoscopic treatment modalities, embolization or surgery. We report here a case of a Dieulafoy lesion in an 11-year-old boy who had recurrent bleeding from the lesion in the duodenal bulb after endoscopic epinephrine injection and surgical ligation, that was successfully treated using coil embolization.
