Sunitinib as a multitarget tyrosine kinase inhibitor is one of the anti-tumor agents, approved by the United States Food and Drug Administration to use treat gastrointestinal stromal tumor and metastatic renal cell carcinoma. The agent is known to commonly induce adverse reactions such as fatigue, nausea, diarrhea, stomatitis, esophagitis, hypertension, skin toxicity, reduciton in cardiac output of left ventricle, and hypothyroidism. However, it has been reported to rarely induce adverse reactions such as nephrotic syndrome and irreversible reduction in renal functions, and cases of intestinal perforation or pneumatosis interstinalis as such reactions have been consistently reported. In this report, a 66-year old man showing abdominal pain had renal cell carcinoma and history of sunitinib at a dosage of 50 mg/day on a 4-weeks-on, 2-weeks-off schedule. Seven days after the third cycle he was referred to the hospital because of abdominal pain. Computed tomography showed pneumoperitoneum with linear pneumatosis intestinalis in his small bowel. The patient underwent surgical exploration that confirmed the pneumatosis intestinalis at 100 cm distal to Treitz's ligament. We report a rare case of intestinal perforation with pneumatosis intestinalis after administration of sunitinib to a patient with metastatic renal cell carcinoma.

OBJECTIVE: To identify the usefulness of both the Bayley Scales of Infant and Toddler Development, 3rd edition (Bayley-III) and Denver Developmental Screening Test II (DDST-II) in preterm babies with neurodevelopmental impairment, considering the detection rate as regulation of criteria. METHODS: Retrospective medical chart reviews which included the Bayley-III and DDST-II, were conducted for 69 preterm babies. Detection rate of neurodevelopmental impairment in preterm babies were investigated by modulating scaled score of the Bayley-III. The detection rate of DDST-II was identified by regarding more than 1 caution as an abnormality. Then detection rates of each corrected age group were verified using conventional criteria. RESULTS: When applying conventional criteria, 22 infants and 35 infants were detected as preterm babies with neurodevelopmental impairment, as per the Bayley-III and DDST-II evaluation, respectively. Detection rates increased by applying abnormal criteria that specified as less than 11 points in the Bayley-III scaled score. In DDST-II, detection rates rose from 50% to 68.6% using modified criteria. The detection rates were highest when performed after 12 months corrected age, being 100% in DDST II. The detection rate also increased when applying the modified criteria in both the Bayley-III and DDST-II. CONCLUSION: Accurate neurologic examination is more important for detection of preterm babies with neurodevelopmental impairment. We suggest further studies for the accurate modification of the detection criteria in DDST-II and the Bayley-III for preterm babies.

BACKGROUND/AIMS: Recent studies have demonstrated that magnifying endoscopy with narrow band imaging (ME-NBI) facilitates differentiation of early gastric cancer from gastric adenoma using vessel plus surface (VS) classification. This study estimated the interobserver and intraobserver agreement of endoscopists using the Yao VS classification system for the gastric mucosal surface. METHODS: We retrospectively reviewed patients who underwent endoscopic submucosal dissection or endoscopic mucosal resection, and selected cases in which preoperative ME-NBI was conducted. Before testing endoscopists, a 20-minute training module was given. Static ME-NBI images (n=47 cases) were presented to seven endoscopists (two experts and five trainees) who were asked to assess the images in 20 seconds using the Yao VS classification system. After 2 weeks, the endoscopists were asked to analyze the images again. The kappa statistic was calculated for intraobserver and interobserver variability. RESULTS: The mean kappa for intraobserver agreement was 0.69 (experts, 0.74; trainees, 0.64). The mean kappa for interobserver agreement was 0.42 (experts, 0.49; trainees, 0.40). CONCLUSIONS: We obtained reliable results as assessed by observer variability, with only brief training on VS classification. The VS classification appears to provide an objective assessment of ME-NBI for trainees who are not familiar with ME-NBI.

The aim of this study was to assess changes between primary classification of esophageal motility disease and follow-up classification by high resolution manometry (HRM) and to determine whether previously classified diseases could be recategorized according to the updated Chicago Classification published in 2011. We reviewed individual medical records and HRM findings twice for each of 13 subjects. We analyzed primary and follow-up HRM findings based on the original Chicago Classification. We then reclassified the same HRM findings according to the updated Chicago Classification. This case series revealed the variable course of esophageal motility disorders; some patients experienced improvement, whereas others experienced worsening symptoms. Four cases were reclassified from variant achalasia to peristaltic abnormality, one case from diffuse esophageal spasm to type II achalasia and one case from peristaltic abnormality to variant achalasia. Four unclassified findings were recategorized as variant achalasia. In conclusion, esophageal motility disorders are variable and may not be best conceptualized as an independent group. Original classifications can be recategorized according to the updated Chicago Classification system. More research is needed on this topic.

Mucinous gastric carcinoma (MGC) is an unusual histologic subtype, and early detection of MGC is very rare. Early-stage MGC appears as an elevated lesion resembling a submucosal tumor (SMT) due to abundant mucin pools in the submucosa or mucosa. We report a rare case of SMT-like early-stage MGC. Tumor type was predicted preoperatively based on characteristic endoscopic findings, in which an SMT-like mass was observed at the gastric fundus. The tumor was covered by nearly normal mucosa, but with an opening allowing for the passage of copious mucus discharge. A total gastrectomy with Roux-en-Y esophagojejunostomy was subsequently performed. Histopathology of the tumor revealed early-stage (lamina propria) mucinous adenocarcinoma.

BACKGROUND: Previously, cutaneous lymphomas were classified according to either the European Organization for the Research and Treatment of Cancer (EORTC) or the World Health Organization (WHO) classification paradigms. The aim of this study was to determine the relative frequency of Korean cutaneous lymphoma according to the new WHO-EORTC classification system. METHODS: A total of 517 patients were recruited during a recent 5 year-period (2006-2010) from 21 institutes and classified according to the WHO-EORTC criteria. RESULTS: The patients included 298 males and 219 females, and the mean age at diagnosis was 49 years. The lesions preferentially affected the trunk area (40.2%). The most frequent subtypes in order of decreasing prevalence were mycosis fungoides (22.2%), peripheral T-cell lymphoma (17.2%), CD30+ T-cell lymphoproliferative disorder (13.7%), and extranodal natural killer/T (NK/T) cell lymphoma, nasal type (12.0%). Diffuse large B-cell lymphoma accounted for 11.2% of cases, half of which were secondary cutaneous involvement; other types of B-cell lymphoma accounted for less than 1% of cases. CONCLUSIONS: In comparison with data from Western countries, this study revealed relatively lower rates of mycosis fungoides and B-cell lymphoma in Korean patients, as well as higher rates of subcutaneous panniculitis-like T-cell lymphoma and NK/T cell lymphoma.

Standard antituberculous therapy, including isoniazid (INH), rifampin, ethambutol, and pyrazinamide (PZA), is widely used to treat active tuberculosis. The most important side effect is hepatotoxicity. In a standard four-drug regimen, PZA was the most common cause of drug-induced hepatitis and was dose-related. The incidence of drug-induced hepatitis is high at doses of 40~70 mg/kg per day but has fallen significantly since the recommended dose was reduced. Liver toxicity induced by PZA is rare at doses of 25 mg/kg per day or less. PZA-induced fulminant hepatic failure is also rare but fatal. We report a case of fulminant hepatic failure caused by a re-challenge of PZA.

This report provides a detailed description of the methodology for ophthalmic examinations according to the Korea National Health and Nutrition Examination Survey (KNHANES) VII and VIII (from 2017 to 2021). The KNHANES is a nationwide survey which has been performed since 1998 in representatives of whole Korean population. During the KNHANES VII and VIII, in addition to the ophthalmic questionnaire, intraocular pressure measurement, visual field test, auto refractometry, axial length and optical coherence tomography measurements were included. This new survey will provide not only provide normative and pathologic ophthalmic data including intraocular pressure, refractive error, axial length, visual field and precise measurement of anterior segment, macula and optic nerve with optical coherence tomography, but also a more accurate diagnosis for major adult blindness diseases, including age-related macular degeneration, diabetic retinopathy, glaucoma, and other ocular diseases, for the national Korean population.
