Background: Atopic dermatitis (AD) is a common skin disease with a wide range of symptoms. Due to the rapidly changing treatment landscape, regular updates to clinical guidelines are needed. Objective: This study aimed to update the guidelines for the treatment of AD to reflect recent therapeutic advances and evidence-based recommendations. Methods: The Patient characteristics, type of Intervention, Control, and Outcome framework was used to determine 48 questions related to AD management. Evidence was graded, recommendations were determined, and, after 2 voting rounds among the Korean Atopic Dermatitis Association (KADA) council members, consensus was achieved. Results: This guideline provides treatment guidance on advanced systemic treatment modalities for AD. In particular, the guideline offers up-to-date treatment recommendations for biologics and Janus-kinase inhibitors used in the treatment of patients with moderate to severe AD.It also provides guidance on other therapies for AD, along with tailored recommendations for children, adolescents, the elderly, and pregnant or breastfeeding women. Conclusion KADA’s updated AD treatment guidelines incorporate the latest evidence and expert opinion to provide a comprehensive approach to AD treatment. The guidelines will help clinicians optimize patient-specific therapies.

Evidence was graded, recommendations were determined, and, after 2 voting rounds among the Korean Atopic Dermatitis Association (KADA) council members, consensus was achieved. Results: The guidelines provide detailed recommendations on foundational therapies, including the use of moisturizers, cleansing and bathing practices, allergen avoidance, and patient education. Guidance on topical therapies, such as topical corticosteroids and calcineurin inhibitors, is also provided to help manage inflammation and maintain skin barrier function in patients with AD. Additionally, recommendations on conventional systemic therapies, including corticosteroids, cyclosporine, and methotrexate, are provided for managing moderate to severe AD. Conclusion KADA’s updated AD guidelines offer clinicians evidence-based strategies focused on basic therapies, topical therapies, and conventional systemic therapies, equipping them to enhance quality of care and improve patient outcomes in AD management.

Background: In 2006, the Korean Atopic Dermatitis Association (KADA) working group released the diagnostic criteria for Korean atopic dermatitis (AD). Recently, more simplified, and practical AD diagnostic criteria have been proposed. Objective: Based on updated criteria and experience, we studied to develop and share a consensus on diagnostic criteria for AD in Koreans. Materials and Methods: For the diagnostic criteria, a questionnaire was constructed by searching the English-language literature in MEDLINE and the Cochrane Database of Systematic Reviews. A modified Delphi method composed of 3 rounds of email questionnaires was adopted for the consensus process. Fifty-four KADA council members participated in the 3 rounds of votes and expert consensus recommendations were established. Results: Diagnostic criteria for AD include pruritus, eczema with age-specific pattern, and chronic or relapsing history. Diagnostic aids for AD encompass xerosis, immunoglobulin E reactivity, hand–foot eczema, periorbital changes, periauricular changes, perioral changes, nipple eczema, perifollicular accentuation, and personal or family history of atopy. Conclusion This study streamlined and updated the diagnostic criteria for AD in Korea, making them more practicable for use in real-world clinical field.

PURPOSE: Nutritional therapy (NT), such as enteral nutrition (EN) or parenteral nutrition (PN), is essential for the malnourished patients. Although the complications related to NT has been well described, multicenter data on symptoms in the patients with receiving NT during hospitalization are still lacking. METHODS: Nutrition support team (NST) consultations, on which NT-related complications were described, were collected retrospectively for one year. The inclusion criteria were patients who were (1) older than 18 years, (2) hospitalized, and (3) receiving EN or PN at the time of NST consultation. The patients' demographics (age, sex, body mass index [BMI]), type of NT and type of complication were collected. To compare the severity of each complication, the intensive care unit (ICU) admission, hospital stay, and type of discharge were also collected. RESULTS: A total of 14,600 NT-related complications were collected from 13,418 cases from 27 hospitals in Korea. The mean age and BMI were 65.4 years and 21.8 kg/m2. The complications according to the type of NT, calorie deficiency (32.4%, n=1,229) and diarrhea (21.6%, n=820) were most common in EN. Similarly, calorie deficiency (56.8%, n=4,030) and GI problem except for diarrhea (8.6%, n=611) were most common in PN. Regarding the clinical outcomes, 18.7% (n=2,158) finally expired, 58.1% (n=7,027) were admitted to ICU, and the mean hospital days after NT-related complication were 31.3 days. Volume overload (odds ratio [OR]=3.48) and renal abnormality (OR=2.50) were closely associated with hospital death; hyperammonemia (OR=3.09) and renal abnormality (OR=2.77) were associated with ICU admission; “micronutrient and vitamin deficiency” (geometric mean [GM]=2.23) and volume overload (GM=1.61) were associated with a longer hospital stay. CONCLUSION: NT may induce or be associated with several complications, and some of them may seriously affect the patient's outcome. NST personnel in each hospital should be aware of each problem during nutritional support.

PURPOSE: Laparoscopy-assisted distal gastrectomy for early gastric cancer has gained acceptance and popularity worldwide. However, laparoscopy-assisted distal gastrectomy for advanced gastric cancer is still controversial. Therefore, we propose this prospective randomized controlled multi-center trial in order to evaluate the safety and feasibility of laparoscopy assisted D2-gastrectomy for advanced stage gastric cancer. MATERIALS AND METHODS: Patients undergoing distal gastrectomy for advanced gastric cancer staged cT2/3/4 cN0/1/2/3a cM0 by endoscopy and computed tomography are eligible for enrollment after giving their informed consent. Patients will be randomized either to laparoscopy-assisted distal gastrectomy or open distal gastrectomy. Sample size calculation revealed that 102 patients are to be included per treatment arm. The primary endpoint is the non-compliance rate of D2 dissection; relevant secondary endpoints are three-year disease free survival, surgical and postoperative complications, hospital stay and unanimity rate of D2 dissection evaluated by reviewing the intraoperative video documentation. DISCUSSION: Oncologic safety is the major concern regarding laparoscopy-assisted distal gastrectomy for advanced gastric cancer. Therefore, the non-compliance rate of clearing the N2 area was chosen as the most important parameter for the technical feasibility of the laparoscopic procedure. Furthermore, surgical quality will be carefully reviewed, that is, three independent experts will review the video records and score with a check list. For a long-term result, disease free survival is considered a secondary endpoint for this trial. This study will offer promising evidence of the feasibility and safety of Laparoscopy-assisted distal gastrectomy for advanced gastric cancer.Trial Registration: NCT01088204 (international), NCCCTS-09-448 (Korea).

A 65-year-old man was admitted due to low grade fever, dry coughing, and dyspnea on exertion. The chest radiograph and CT scan showed diffuse ground glass opacities and small nodules in the both lung fields resulting in a diagnosis of severe interstitial pneumonia. Conservative treatment with antibiotics and bronchodilators decreased the symptoms, but the dyspnea and cough reappeared when he returned home. An inspection of his house revealed the presence of fungi under the wallpaper. His symptoms disappeared completely after these were removed. His clinical course raised the suspicion of hypersensitivity pneumonitis and these fungi believed to be the cause of hypersensitivity pneumonitis. The histological findings of a lung specimen by video-assisted thorachoscopy were compatible with hypersensitivity pneumonitis. The fungi were identified as Alternaria.

A primary pulmonary malignant lymphoma is a rare disease. It is thought to be a category of non-Hodgkin's lymphoma arising from the bronchous-associated lymphoid tissue (BALT). The majority of primary pulmonary lymphomas are low-grade, small B-cell lymphomas, which are associated with Sjogren's syndrome and similar autoimmune disorders. A case of primary pulmonary low-grade B-cell lymphoma arising from the BALT was encountered in a patient with systemic lupus erythematosus. A 54-year-old man was admitted to the hospital for the evaluation of left pleuritic chest pain and multiple joint pain in both hands. Serologic tests for collagen vascular disease were performed. The results of ANA and anti-ds-DNA were all positive. The computed tomography of the chest showed patchy concolidations in the left lower lobe with a pleural effusion and a video-assisted thoracoscopic biopsy was performed. Here we report a case of low-grade B-cell lymphoma of BALT in a patient with systemic lupus erythematosus with a review of the relevant leteratures.

Transient peripheral eosinophilia occurs in several disorders, such as allergic diseases, cancer, and parasitic in fections. However, in most cases, their persence is not accompanied by tissue destruction or organ dysfunc tion. In certain disease states, eosinophils can accumulate in any organ in the body and cause tissue destruction as a result of the eosinophil infiltration or the toxic effects of the degranulated proinflammatory products. Idiopathic hypereosinopilic syndrome is a rare disorder characterized by persistent eosinophilia of an unknown origin, usually associated with a dysfunction of organs such as the heart, lung, skin, and nervous system. Idiopathic hypereosinophilic syndrome usually has an indolent course over a period of several months. However, in some cases, they have grave symptoms if vital organs such as heart and lung are infiltrated. Here we report a case of idiopathic hypereosinophilic syndrome presenting acute pulmonary edema involving the heart, bone marrow, and lung with a review of the relevant literatures.

Carcinomas are malignant neoplasms composed of epithelial cells and epithelial cancers are rare in the young. When it comes to colorectal carcinoma, the incidence of the large bowel has been noted with increasing frequency in the younger population, but this disease has remained very rare in children. Only 1% of all malignant growths of the large intestine arise in persons under 20 years of age. Inspite of these facts, the colon is the most common site of gastrointestinal carcinoma in children. While the prognosis is relatively acceptable in adults, it is very gloomy in children. Of all the histologic categories of colorectal cancer, the mucinous variety, which accounts for approximately 15% of adult colorectal carcinoma, is the predominant histologic variety in patients younger than 20 years of age at the time of diagnosis. Now, only two cases of carcinoma of the colon in children under 15 years of age have been reported in Korea. We report a case of mucinous adenocarcinoma of the colon in a 14-year-old boy with a brief review of the cases on record.

The esophageal hiatal hernia is a herniation of an abdominal organ, usually the stomach, through the esophageal hiatus into thoracic cavity. It is a rare disease, usually congenital and frequently associated with gastroesophageal reflux and other congenital malformations in children. It is classified according to their anatomic characteristics as type I (sliding hiatal hernia), type II (paraesophageal hiatal hernia), type III (combined hiatal hernia) and type IV (multiorgan hiatal hernia). We experienced a case of type III congenital esophageal hiatal hernia simulating chest mass on simple chest x-ray because of right intrathoracic stomach secondary to congenital esophageal hiatal hernia and organoaxial rotation in 10 months male. After the operation, he showed an improved general condition and was discharged at the 14th hospital day. We report the case with the brief review of the related literatures.
