A Case of Skin Sclerosis Associated with Docetaxel Chemotherapy for Non-Small Cell Lung Cancer

A 64-year-old woman was diagnosed with non-small cell lung cancer. Her disease was stage 4 (T2N2M1) with squamous cell carcinoma. She had been treated with docetaxel and carboplatin. After a completion of 11 cycle of chemotherapy, edema appeared on both feet and had spread rapidly up to the pretibial area without response to diuretics. Sclerotic changes and pigmentation followed but both knees and other parts of the body were spared. There was no evidence of vascular occlusions. On serologic tests, antinuclear, anti-centromere, and anti-topoisomerase I antibodies were all negative. A skin biopsy revealed diffuse infiltration of lymphocytes and discretely thickened collagen bundles in the superficial dermis. After discontinuing docetaxel chemotherapy, she was treated with prednisolone and D-penicillamine and sclerotic changes on the lower legs were improved.

The Clinical Significance of Simplified Scoring Criteria as a Diagnostic Tool for Overlap Syndrome in Korea / 대한내과학회지

BACKGROUND/AIMS: The diagnosis of primary billiary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome remains challenging. In 2008, a simplified scoring system was proposed by the International Autoimmune Hepatitis Group, which aimed for wider applicability in routine clinical practice. We evaluated the performance of the new simplified AIH scoring criteria as a diagnostic tool for overlap syndrome. METHODS: We retrospectively reviewed the clinical histories, chemistry, autoimmune studies, and liver biopsy results of 25 patients diagnosed with PBC who visited Soonchunhyang University Hospital, Bucheon and Seoul, between November 2004 and December 2009. Parameters relevant to the revised and simplified scoring criteria were recorded, and outcomes were compared between those with and without features of overlap syndrome. RESULTS: Of 25 patients with a definite diagnosis of PBC, five (20%) were diagnosed with overlap syndrome using the revised criteria, and 18 patients (72%) were diagnosed with the simplified criteria. Those patients diagnosed according to the simplified scoring criteria revealed an increased frequency of anti-nuclear antibody (p = 0.030) and serum IgG levels (p = 0.092). Additionally, advanced fibrosis was significantly more frequent in patients with overlap syndrome (p = 0.017). CONCLUSIONS: The simplified scoring criteria seemed to be useful as a diagnostic tool to recognize overlap syndrome in Korea. However, a relatively small number of patients were included in our study, so further clinical trials based on larger populations should be performed.

The differences of clinical profiles by house dust mite sensitization in patients with asthmatics in Soonchunhyang University Hospital cohort

PURPOSE: The majority of patients with allergic disease are highly sensitized to house dust mites (HDM). There is few data to observe sensitization rate to HDM in asthmatics in Korea. The aim of this study was to observe the differences of clinical profiles by HDM sensitization in patients with asthmatics in Soonchunhyang University Hospital (SCH) cohort. METHODS: We recruited 2,345 asthmatic patients in SCH cohort. Lung function, body mass index and sputum and blood eosinophils, and PC20, and clinical profiles were compared by HDM sensitization. RESULTS: Dermatophagoides farinae (Derf) and/or Dermatophagoides pteronyssinus (Derp) (+) sensitization rate was higher prevalence in male than in female. Compared with nonatopy asthmatics, Derf and/or Derp (+) asthmatics had early onset of age [Derf and/or Derp (+) vs. Derf and Derp (-) vs. atopy (-); 32.5+/-0.51 vs. 36.1+/-0.88 vs. 43.1+/-0.54, P<0.05]. Derf and/or Derp (+) asthmatics had shorter duration of asthma symptom than that of nonatopy asthmatics. Derf and/or Derp (+) asthmatics had lower forced expiratory volume in one second and forced vital capacity than those of Derf and Derp (-) asthmatics. PC20 in Derf and/or Derp (+) asthmatics had lower than those of Derf and Derp (-) and nonatopy asthmatics [Derf and/or Derp (+) vs. Derf and Derp (-) vs. atopy (-); 5.4+/-0.24 mg/mL vs. 6.59+/-0.52 mg/mL vs. 7.19+/-0.33 mg/mL, P<0.05]. Blood eosinophils number in Derf and/or Derp (+) asthmatics had higher than that of nonatopy asthmatics (414.7+/-131.1 vs. 350.6+/-14.0, P<0.05). Total immunoglobulin E (IgE) in Derf and/or Derp positive asthmatics had higher than that of Derf and Derp negative and nonatopy asthmatics. There was no difference of body mass index among three groups. CONCLUSIONS: Our data indicate that atopy asthmatics sensitized to Derf and/or Derp had early onset of age, high total IgE and airway responsiveness, and eosinophilic inflammation.

Two Cases of Ascending Aortic Intramural Hematoma Combined with Cardiac Tamponade Treated with Different Strategies

Aortic intramural hematoma (IMH) is classically defined as a variation of aortic dissection where blood collects within the aortic media without the presence of an intimal flap. Ascending IMH is known to have worse clinical outcomes than IMH of the descending aorta or aortic arch. Therefore, some patients with higher risk of disease progression require surgical corrections. However, the indications and the benefits of surgical management of ascending IMH, compared with medical treatment only, have not yet been established. We present two cases of IMH in the ascending aorta that presented with cardiac tamponade; patients were treated differently according to risk factors.

A Case of Pulmonary Sclerosing Hemangioma with an Increased Size and Chest Discomfort on 10 Years' Follow-up

Pulmonary sclerosing hemangioma is a relatively rare neoplasm of the lung with polymorphic histologic features of 2 unifying cellular components including surface cuboidal cells and interstitial round cells. Pulmonary sclerosing hemangioma typically occurs in middle aged women with asymptomatic, peripheral, solitary, well-circumscribed lesions. Although it is pathologically benign, it reveals size growing and chest symptom. We here report a case of pulmonary sclerosing hemangioma in a 72-year-old woman. She presented chest discomfort. A chest radiography and a chest computed tomography scan showed growing size from 3.2x3.1 cm to 6.0x5.3 cm in left upper lung during 10 years' follow-up period. Surgical resection of lung revealed a distinct constellation of findings including 2 epithelial cell types, surface cells, and round cells, which form 4 architectural patterns, papillary, sclerotic, solid, and hemorrhagic. She was diagnosed as pulmonary sclerosing hemangioma and chest discomfort disappeared.
