We report a case of 53-year-old woman with personification following right middle cerebral artery territory infarction. Although she knew that her paralyzed left limbs belonged to her, she behaved as if it is a separate person. Verbalization of hatred toward her left arm was frequently observed. She attributed her neurologic deficit to the left arm instead of herself, frequently complaining in a fashion that 'I(a person except for the left arm) am all right but he/she(left arm) is wrong'. This delusional beliefs were mainly confined to her paralysed left limb, and were accompanied by left spatial neglect, transient anosognosia for hemiplegia and right-left disorientation.

BACKGROUND & PURPOSE: Ideomotor apraxia is a gestural deficit which is not due to primary sensory or motor deficit, poor auditory comprehension or incooperation. Previous studies on apraxia in AD patients include advanced AD patients who exhibited marked impairment in auditory comprehension, This might have confounded the results of the studies. The purpose of this study is to observe the frequencies and patterns of gestural errors in the early stage of AD. METHOD: Eighteen patients with AD (M : F = 4 : 14, age 62.6 + 7.2) and eighteen age- and sex- matched controls participated in this research. Patients who scored below 80 % of Western Aphasia Battery comprehension subtest and showed marked cognitive impairments were excluded (MMSE; 19.9 + 4.4, CDR 1.1+/- 0.5). Gestures. In response to commands were videotaped and analyzed by 2 neurologists and 1 speech-language pathologist. Test items included 3 types of movements ; 10 limb intrasitive, 15 transitive, and 10 buccofacial. RESULTS: Limb transitive movements were the most affected while buccofacial was the least. The error patterns most frequently observed were body-part-as-objects (BPO, 20%), external configuration orientation (ECO, 16%), and movement error(M, 9%). In comparision, BPO, ECO, M errors in normal control were 2%, 3%, and 4% respectively. In addition, apraxia item, which are to detecting AD were identified. CONCLUSION: It is suggested that the apraxia is commonly associated with AD even in the early stage of the disease and an accurate anaIysis of errors may contribute to establishing an early diagnosis of AD.

Malignant granular cell tumors (MGST) are extremely rare, high-grade sarcoma of schwann cell origin. They often metastasize and are associated with short survival. We described a patient with recurred MGST after wide marginal excision followed by chemotherapy. The histologic findings revealed relapsed MGST containing rich vascular structure. The patient was treated with sunitinib malate (50 mg/day) for three weeks. Because sunitinib malate has a potent antiangiogenic property, we surmised that it might be effective against this type of malignancy. However, he died due to progression of tumor after six weeks. Here, we report it along with the corresponding literature.

Hyperfunctioning thyroid carcinoma is very rare. Hence, radionuclide imaging of thyroid hot nodules usually suggests a benign tumor, and less than 4% of cases have been reported as malignant. We would like to present a case of a hyperfunctioning papillary thyroid carcinoma that was initially treated with radioactive iodine. A 58-year-old woman was referred to our hospital for palpable thyroid nodule and a 5-kg weight loss within 6 months. Thyroid function test revealed thyrotoxicosis, and thyroid autoantibodies were absent. 99mTc thyroid scintigraphy showed a 2 x 2 cm-sized hyperactive hot nodule at the left lobe. Despite radioactive iodine treatment with a dose of 10 mCi 131I, thyroid function did not improve. Fine needle aspiration revealed papillary thyroid cancer. The patient underwent total thyroidectomy. Although clinical features and thyroid scans suggest a benign nodule, the possibility of malignancy should not be ruled out. Malignant thyroid hot nodules are rare; however, its possibility should be taken into account. Therefore, we suggest that ruling out malignancy by existing diagnostic guidelines can misdiagnose even a typical case with benign features. As thyroid nodule detection is getting sensitive and accurate, we present this case to discuss whether additional diagnostic approaches would be necessary for thyroid nodules.

A 30-year-old man was admitted to our hospital because of fatigue, palpitation and severe weakness of both legs. The admission laboratory findings revealed thyrotoxicosis, and 131I thyroid scintigraphic imaging revealed a low radioactive iodine uptake. He was treated for painless thyroiditis for about 4 months. However, thyrotoxic state had continued and radioactive iodine uptake was markedly increased in the follow up scan. Painless thyroiditis often relapses, but rarely develops into Graves' disease. This is a rare case in which painless thyroiditis was followed by Graves' disease.

PURPOSE: We evaluated the effect of early chemoradiotherapy on the treatment of patients with limited stage small cell lung cancer (LS-SCLC). MATERIALS AND METHODS: Between January 2006 and December 2011, thirty-one patients with histologically proven LS-SCLC who were treated with two cycles of chemotherapy followed by concurrent chemoradiotherapy and consolidation chemotherapy were retrospectively analyzed. The chemotherapy regimen was composed of etoposide and cisplatin. Thoracic radiotherapy consisted of 50 to 60 Gy (median, 54 Gy) given in 5 to 6.5 weeks. RESULTS: The follow-up period ranged from 5 to 53 months (median, 22 months). After chemoradiotherapy, 35.5% of the patients (11 patients) showed complete response, 61.3% (19 patients) showed partial response, 3.2% (one patient) showed progressive disease, resulting in an overall response rate of 96.8% (30 patients). The 1-, 2-, and 3-year overall survival (OS) rates were 66.5%, 41.0%, and 28.1%, respectively, with a median OS of 21.3 months. The 1-, 2-, and 3-year progression free survival (PFS) rates were 49.8%, 22.8%, and 13.7%, respectively, with median PFS of 12 months. The patterns of failure were: locoregional recurrences in 29.0% (nine patients), distant metastasis in 9.7% (three patients), and both locoregional and distant metastasis in 9.7% (three patients). Grade 3 or 4 toxicities of leukopenia, anemia, and thrombocytopenia were observed in 32.2%, 29.0%, and 25.8%, respectively. Grade 3 radiation esophagitis and radiation pneumonitis were shown in 12.9% and 6.4%, respectively. CONCLUSION: We conclude that early chemoradiotherapy for LS-SCLC provides feasible and acceptable local control and safety.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are potentially fatal acute hypersensitivity reactions that involve the skin and mucous membranes. Because they are relatively rare diseases, it is difficult to obtain well-organized epidemiological data. The clinicodemographic characteristics, culprit drugs, and factors related to disease prognosis may vary. Objective: To identify the characteristics of SJS/TEN by investigating patient clinicopathological characteristics, laboratory findings, suspected drugs, and mortality through a retrospective study using medical record data. Methods: The clinical records of patients diagnosed with SJS/TEN between February 2009 and February 2019 at three medical institutions of Soonchunhyang University were retrospectively reviewed. Data pertaining to sex, age, history, suspected drugs, latent period, laboratory findings, and mortality were collected, and their correlations were analyzed. Results: We identified SJS/TEN in 88 patients. Among the probable causative agents, antibiotics were the most common (29 cases, 33.0%), followed by nonsteroidal anti-inflammatory drugs (NSAIDs) in 20 cases (22.7%). The period between drug administration and symptom onset varied with the causative agent. Patients who died had high SCORTEN scores. In addition, hypertension, diabetes, renal failure, and cardiac disease had a statistically significant association with high SCORTEN. Conclusion Antibiotics, NSAIDs, antiepileptics and allopurinol were the most commonly implicated drugs in our retrospective study. There was a significant correlation between comorbidities. Because SJS/TEN is a life-threatening condition, early recognition of the suspected drug are important. The results of this study may provide insights that aid in the early diagnosis and prediction of disease outcomes of SJS/TEN in the Korean population.

Erythema nodosum (EN) is the most common form of panniculitis and may be triggered by a variety of stimuli, including infections, drugs, pregnancy, sarcoidosis, inflammatory bowel disease, and malignancies. Rare cases of vaccination-related EN have been reported, but none due to the coronavirus disease 2019 (COVID-19) vaccine of Pfizer have been documented. We report a case of EN associated with the Pfizer vaccine. A 43-year-old woman presented with acute-onset painful nodular lesions that appeared bilaterally on the extensor surface of the lower legs. These lesions appeared 5 days after the first dose of Pfizer vaccination. The patient reported no recent infectious history other than fever for 3 days after vaccination. Skin biopsy revealed inflammation extending into the subcutaneous fat with a septal distribution. It is important for physicians to be aware of the side effects of the COVID-19 vaccine because more people are bound to be vaccinated.

Prurigo pigmentosa (PP) is a rare inflammatory skin disease that commonly affects Asian women. It is characterized by symmetric pruritic eruptions in a reticular pattern, primarily on the back, chest, or neck. The etiology of PP is unclear; however, it is estimated that neutrophil-mediated inflammation of the skin is induced by various exogenous stressors, such as friction from clothing and sweating. In addition to exogenous factors, some cases are thought to be related to ketosis, diabetes mellitus, fasting, or dieting to lose weight. With the increasing popularity of ketogenic diets, cases of PP are being more commonly reported. To raise awareness of this disease, we present two cases of PP that occurred after following a ketogenic diet.
