Myxoma of Nasal Ala in an Adult Patient / 대한이비인후과학회지

Myxoma most commonly occurs in the atria, but is rare in the nasal cavity. A 58-year-old male patient presented with a nasal mass. We used endoscopic endonasal approach for treatment, and the patient was finally diagnosed with nasal ala myxoma. We report here a rare case of a patient with nasal ala myxoma along with a literature review.

Pharyngeal Closure Reinforced With Sternohyoid and Omohyoid Muscle After Total Laryngectomy / 대한이비인후과학회지

Pharyngocutaneous fistula occurring after total laryngectomy is a bothersome complication as it can even cause a massive bleeding due to carotid artery rupture. Preoperative radiation, extensive diseases which need flap reconstruction, low albumin or hemoglobin level, history of smoking, or underlying diseases have been domestically reported to have a relationship with the condition. To reduce this complication, simultaneous coverage for the pharyngeal closure has been developed using flaps, such as the pectoralis major muscle, the radial forearm or the anterolateral thigh, which are distant from the radiation field. However, these methods need additional surgical techniques and times. Another method advocated is pharyngeal reinforcement using flaps that can be easily obtained from the same surgical field, such as the sternocleidomastoid or the infrahyoid muscle or the acellular dermal graft with relative significances. Here we suggest reinforcement of pharyngeal closure after total laryngectomy using the sternohyoid and omohyoid muscle flaps.

Factors associated with Experience of Diagnosis and Utilization of Chronic Diseases among Korean Elderly : Focus on Comparing between Urban and Rural Elderly / 農村醫學 地域保健

OBJECTIVES@#The purpose of this study was to identify and compare the difference and related factors with general characteristic and health behaviors, a experience of diagnosis and treatment of chronic diseases between rural and urban among elderly in Korea.@*METHODS@#We used the data of Community Health Survey 2017 which were collected by the Korean Center for Disease Control and Prevention. The study population comprised 67,835 elderly peopled aged 65 years or older who participated in the survey. The chi-square test, univariate and multivariate logistic regression analysis were used to analyze data.@*RESULTS@#We identified many significant difference of health behaviors, an experience of diagnosis and treatment with chronic diseases between rural and urban. Compared to urban elderly, the odds ratios (ORs) (95% confidence interval) of rural elderly were 1.136 (1.092–1.183) for diagnosis of diabetes, 1.278 (1.278–1.386) for diagnosis of dyslipidemia, 0.940 (0.904–0.977) for diagnosis of arthritis, 0.785(0.736–0.837) for treatment of arthritis, 1.159 (1.116–1.203) for diagnosis of cataracts, and 1.285(1.200–1.375) for treatment of cataracts. In the experience of diagnosis and treatment of chronic diseases, various variables were derived as contributing factors for each disease. Especially, there were statistically significant difference in the experience of diabetes diagnosis, arthritis diagnosis, cataract diagnosis and dyslipidemia except for hypertension diagnosis (p<0.01) between urban and rural elderly. There were statistically significant differences in the experience of treatment for arthritis and cataract (p<0.01), but there was no significant difference in the experience of treatment for hypertension, diabetes, dyslipidemia between urban and rural elderly.@*CONCLUSION@#Therefore, it would be necessary to implement a strategic health management project for diseases that showed significant experience of chronic diseases with diagnosis and treatment, reflecting the related factors of the elderly chronic diseases among the urban and rural areas.

Classify the Acute Drug Intoxication Patients with Poisoning Severity Score(PSS) and Calculate the Optimal Cutoff Value of PSS, PSSsum to Predict Poor Prognosis

PURPOSE: This study examined the Poisoning Severity Score (PSS) from acute poisoning patients, to determine the relationships among the PSS, PSSsum, the primary outcome (prolonged stay at the ER over 24 hours, general ward and ICU admission and the application of intubation and mechanical ventilator, and the administration of inotropes). METHODS: A retrospective study was conducted through the EMR for 15 months. The PSS grade was classified according to the evidence of symptoms and signs. The differences in the primary outcomes between the PSS of when a single organ was damaged, and the PSS, PSSsum combined with the grade of when multiple organs were damaged, were studied. The cutoff value was calculated using the receiving operating characteristics (ROC) curve. RESULTS: Of the 284 patients; 85 (29.9%) were men with a mean age of 48.8 years, and their average arrival time to the ER was 4.4±6.7 hours. The most frequently used drug was hypnotics. The number of patients with PSS grade 0, 1, 2, 3, and 4 was 17, 129, 122, 24, and one, respectively. No ICU admissions, application of intubation and mechanical ventilators, administration of inotropes were observed among the patients with PSS grades 0 and 1 but only on patients with PSS grades 2 to 4. At PSS, when separating the patients according to the number of damaged organs, 17 had no symptoms, 133 had one organ damaged, 75 had two organs damaged, 36 had three organs damaged, and 23 had four organs damaged. Significant differences were observed between increasing number of damaged organs and the primary outcome. CONCLUSION: Among the acute poisoning patients, the PSS was higher in severity when the grade was higher. The number of damaged organs and the primary outcome showed meaningful statistical differences. This study confirmed that when the patients' PSS>2 and PSSsum>5, the frequency of ICU admission was higher, and they were considered to be severe with an increased prescription risk of application of intubation and mechanical ventilator, and the administration of inotropes.

Prediction of survival by applying current prognostic models in diffuse large B-cell lymphoma treated with R-CHOP followed by autologous transplantation

BACKGROUND: Among the currently available prognostic models for diffuse large B-cell lymphoma (DLBCL), we investigated to determine which is most adoptable for DLBCL patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) followed by upfront autologous stem cell transplantation (auto-SCT). METHODS: We retrospectively evaluated survival differences among risk groups based on the International Prognostic Index (IPI), the age-adjusted IPI (aaIPI), the revised IPI (R-IPI), and the National Comprehensive Cancer Network IPI (NCCN-IPI) at diagnosis in 63 CD20-positive DLBCL patients treated with R-CHOP followed by upfront auto-SCT. RESULTS: At the time of auto-SCT, 74.6% and 25.4% of patients had achieved complete remission and partial remission after R-CHOP, respectively. As a whole, the 5-year overall (OS) and progression-free survival (PFS) rates were 78.8% and 74.2%, respectively. The 5-year OS and PFS rates according to the IPI, aaIPI, R-IPI, and NCCN-IPI did not significantly differ among the risk groups for each prognostic model (P-values for OS: 0.255, 0.337, 0.881, and 0.803, respectively; P-values for PFS: 0.177, 0.904, 0.295, and 0.609, respectively). CONCLUSION: There was no ideal prognostic model among those currently available for CD20-positive DLBCL patients treated with R-CHOP followed by upfront auto-SCT.

R-CHOP chemoimmunotherapy followed by autologous transplantation for the treatment of diffuse large B-cell lymphoma

BACKGROUND: We investigated factors that influence outcomes in diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab combined with the CHOP regimen (R-CHOP) followed by upfront autologous stem cell transplantation (Auto-SCT). METHODS: We retrospectively evaluated survival differences between subgroups based on the age-adjusted International Prognostic Index (aaIPI) and revised-IPI (R-IPI) at diagnosis, disease status, and positron emission tomographic/computerized tomographic (PET/CT) status at transplantation in 51 CD20-positive DLBCL patients treated with R-CHOP followed by upfront Auto-SCT. RESULTS: Patients had either stage I/II bulky disease (5.9%) or stage III/IV disease (94.1%). The median patient age at diagnosis was 47 years (range, 22-66 years); 53.3% and 26.7% had high-intermediate and high risks according to aaIPI, respectively. At the time of Auto-SCT, 72.5% and 27.5% experienced complete (CR) and partial remission (PR) after R-CHOP, respectively. The median time from diagnosis to Auto-SCT was 7.27 months (range, 3.4-13.4 months). The 5-year overall (OS) and progression-free survival (PFS) were 77.3% and 72.4%, respectively. The 5-year OS and PFS rates according to aaIPI, R-IPI, and PET/CT status did not differ between the subgroups. More importantly, the 5-year OS and PFS rates of the patients who achieved PR at the time of Auto-SCT were not inferior to those of the patients who achieved CR (P=0.223 and 0.292, respectively). CONCLUSION: Survival was not influenced by the aaIPI and R-IPI at diagnosis, disease status, or PET/CT status at transplantation, suggesting that upfront Auto-SCT might overcome unfavorable outcomes attributed to PR after induction chemoimmunotherapy.

Effective Treatment of Intractable Diarrhea Associated with Common Variable Immunodeficiency with Oral Budesonide / 대한내과학회지

Common variable immunodeficiency (CVID) is the most common symptomatic primary antibody deficiency syndrome and has a high prevalence of gastrointestinal complications. We report the case of a 36-year-old male with CVID who presented with chronic intractable diarrhea and malabsorption. A comprehensive evaluation revealed no secondary causes of his symptoms. He was treated symptomatically without improvement. After receiving systemic steroid treatment, his symptoms improved, but returned soon after tapering the steroid. When he was subsequently administered oral budesonide, his symptoms and quality of life improved; this effect lasted for 20 months without unacceptable side effects.

Tuberculous Peritonitis Mimicking Primary Peritoneal Carcinoma

Tuberculous peritonitis is one of the most common extrapulmonary tuberculosis. The presenting signs and symptoms, together with the carbohydrate antigen (CA) 125 status and imaging findings may resemble the primary peritoneal carcinoma or ovarian carcinoma. We herein report a case on a 71-year-old woman who is presented with abdominal distension, abdominal pain, nausea, anorexia. Abdomino-pelvic computed tomography scans reveal large amounts of ascites and mottled omentum with diffuse nodular masses, and the serum CA 125 level is elevated. The initial clinical diagnosis is the primary peritoneal carcinoma, but the final histological diagnosis confirms the tuberculous peritonitis. Thus, we discuss the differential diagnosis of tuberculous peritonitis from primary peritoneal carcinoma and also the problems especially found in old aged patients. In conclusion, although the elderly patients are suspected with malignancy, we should keep in mind the possibility of curable diseases and perform laparoscopic biopsy during the early stage aggressively.

Early Gastric Cancer with Cellulitis-like Skin Metastasis / 대한소화기학회지

Skin metastasis from internal carcinoma rarely occurs and it has an incidence of 0.7% to 9%. Although the prognosis of the skin metastases varies considerably depending on the type of the primary malignancy, presence of metastatic skin cancer usually implies a widespread systemic disease and a high mortality. A 50-year-old Korean male patient visited Dankook University Hospital for evaluation of skin rash on his whole abdomen of about 1 month's duration. He had undergone laparoscopy-assisted distal gastrectomy due to early gastric cancer about 3 months ago. He did not complain of any noticeable symptoms like febrile sense or pruritus. Skin biopsy was performed on the periumbilical area at previous port site and around the scar. Microscopic examination revealed multiple malignant cells in lymphatic spaces, consistent with metastatic carcinoma. He was therefore diagnosed with isolated skin metastasis from early gastic cancer. Because of patient's poor liver function, systemic chemotherapy could not be performed and only best supportive care was provided. Herein, we report a rare case of cellulitis-like skin metastasis from early gastric cancer with a brief review of the literature.

Malignant Perivascular Epithelioid Cell Tumor (PEComa) Arising in the Omentum with Metastatic Peritoneal Seeding: A Case Report / 대한내과학회지

The World Health Organization (WHO) defines a perivascular epithelioid cell tumor (PEComa) as a mesenchymal neoplasia composed of perivascular epithelioid cells with characteristic morphological and immunohistochemical features. They are rarely malignant. Indeed, only a few cases have been reported in the English literature, and this is the first case of PEComa reported in Korea. A 64-year-old man presented with an abdominal mass and peritoneal seeding. The patient underwent mass excision with descending colon resection and anastomosis. The primary mass and peritoneal seeding was diagnosed as a PEComa histopathologically. Seven months later, he developed liver metastasis and aggravated peritoneal seeding. Here, we report a case of malignant PEComa of the omentum.

Quadruple Mtachronous Primary Neoplasms in the Aerodigestive Tract / 대한내과학회지

Multiple primary neoplasms, defined as the occurrence of multiple malignant neoplasms in the same individual, were first reported by Billroth in 1889. With gradual improvements in diagnostics, and the early detection and effective treatment of malignant neoplasms, the prevalence of multiple primary neoplasms seems to be increasing. Although there have been several reports of triple primary neoplasms in Korea, cases of quadruple neoplasms are rare. Recently, we diagnosed a 69-year-old male with primary neoplasms in the lung, esophagus, vocal cords, and hypopharynx. The authors report this rare case of four metachronous primary neoplasms and provide a review of the literature.

A Case of Secondary Gout Associated with Essential Thrombocythemia

Gouty arthritis is a metabolic disorder characterized by hyperuricemia, deposition of monosodium urate crystal in the joints, and recurrent episodes of acute inflammatory arthritis. Depending on the actual causes of hyperuricemia, gout is classified as primary or secondary gout. In myeloproliferative neoplasms, a turnover of nucleic acids is greatly augmented and therefore the blood concentration of uric acid may be markedly increased. But an acute attack of gout is extremely rare in patients with myeloproliferative neoplasms. Essential thrombocythemia, one of the myeloproliferative neoplasms, is characterized by megakaryocytic hyperplasia in bone marrow and marked thrombocytosis. We report a case of secondary gout in a 66-year-old man with essential thrombocythemia.

Everolimus-Induced Interstitial Pneumonitis in a Patient with Metastatic Renal Cell Carcinoma: a Case Report / 대한내과학회지

Everolimus, an inhibitor of the mammalian target of rapamycin, is an active agent against metastatic renal cell carcinoma. Treatment with everolimus prolongs progression-free survival in patients with clear cell-type renal cell carcinoma that has progressed on vascular endothelial growth factor receptor tyrosine kinase inhibitors, such as sunitinib and/or sorafenib. Everolimus-induced interstitial pneumonitis is not rare and is sometimes fatal. Due to the potential for pulmonary toxicity due to everolimus, it is recommended that pulmonary complications be periodically evaluated. We report a case of everolimus-associated interstitial pneumonitis in a patient with metastatic renal cell carcinoma.

A Retrospective Study of First-Line Combination Chemotherapy in Advanced Colorectal Cancer: A Korean Single-Center Experience / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: Fluoropyrimidine-based combination chemotherapy, in combination with either oxaliplatin or irinotecan, has demonstrated efficacy and tolerability in treatment of advanced colorectal cancer (ACC). MATERIALS AND METHODS: Between January 2006 and December 2007, a total of 478 ACC patients were treated with combination chemotherapy in first-line settings. Combination therapies included: 5-fluorouracil, folinic acid plus oxaliplatin (FOLFOX, n=172), 5-fluorouracil, folinic acid plus irinotecan (FOLFIRI, n=95), capecitabine plus oxaliplatin (XELOX, n=155), and capecitabine plus irinotecan (XELIRI, n=56). FOLFOX and FOLFIRI were repeated every 2 weeks, whereas XELOX and XELIRI were repeated every 3 weeks until occurrence of disease progression or unacceptable toxicity, or until a patient chose to discontinue treatment. RESULTS: The median age was 58 years (range, 19 to 84 years) and the median chemotherapy durations for FOLFOX, FOLFIRI, XELOX, and XELIRI were 4.9, 4.5, 5.7, and 5.4 months, respectively. Combination chemotherapy regimens were generally well tolerated. The estimated median progression-free-survival (PFS) for all patients was 6.8 months (95% confidence interval, 6.3 to 7.3 months). No statistically significant difference in PFS was found among regimens used as first-line chemotherapy. Sixty percent (n=290) of patients received second or further lines of therapy after failure. CONCLUSION: Fluoropyrimidine-based combination chemotherapy regimens appear to be equally active and tolerable as first-line therapy for ACC.

A Case of Primary Colonic Lymphoma with Peritoneal Carcinomatosis and Pleural Effusion / 대한소화기내시경학회지

Primary gastrointestinal lymphomas are quite rare with the stomach and small bowel being the most frequent site. Colon involvement is observed in only 10~20% of all gastrointestinal lymphomas. A colonic lymphoma presents with non-specific abdominal pain, weight loss, a change in bowel habits, bleeding, intestinal obstruction, intussusception and a palpable mass. A colonic lymphoma can be indicated using a barium enema, abdominal CT and colonoscopy. The correct diagnosis is obtained by a colonoscopic biopsy. We report a case of primary colonic non-Hodgkin's lymphoma with peritoneal carcinomatosis and a right pleural effusion.
