Large cell neuroendocrine carcinoma (LCNEC) of the lung is a newly recognized entity of pulmonary neuroendocrine carcinoma. Histologically, it is very difficult to differentiate LCNEC from other pulmonary carcinomas and the prognosis is significantly poor. The cutaneous metastasis of LCNEC of the lung shares some features with Merkel cell carcinoma of the skin in light microscopy and yet it is negatively stained with cytokeratin 20. We report a case of cutaneous metastasis of LCNEC of the lung, previously misdiagnosed as squamous cell carcinoma. Our patient showed a poor response to the chemotherapy and also revealed a brain metastasis on follow-up brain CT scan.

Purpose: Obesity is associated with nonalcoholic fatty liver disease, one of the most common causes of chronic liver disease.We aimed to demonstrate the effectiveness of bariatric surgery for hepatic steatosis and fibrosis in Korean patients. Methods: A total of 32 consecutive patients were enrolled in this study. Hepatic steatosis and liver fibrosis were assessed before surgery and 6 months after surgery using transient elastography and serologic panels. Results: Thirteen patients (40.6%) were male and 19 (59.4%) were female, with a mean age of 39.3 ± 11.3 years. The body mass index was significant at the 6th month: 39.1 ± 6.7 and 30.3 ± 4.7 kg/m2 (P < 0.001), respectively. The mean preoperative controlled attenuation parameter and liver stiffness measurement values were 325.4 ± 55.9 dB/m and 7.4 ± 4.8 kPa, respectively, before surgery, and they decreased to 267.1 ± 45.1 dB/m and 5.3 ± 2.3 kPa, respectively, 6 months postoperatively (P < 0.001, respectively). Conclusion These results suggest that bariatric surgery is associated with a significant improvement in liver steatosis and fibrosis. Bariatric surgery has a beneficial effect on nonalcoholic fatty liver disease in patients with morbid obesity in Korea.

BACKGROUND: As co-factors of metalloenzymes, zinc(Zn) and copper(Cu) have a considerable effect on nearly all the metabolism that takes place in organs of the body, including the skin. OBJECTIVE: The purpose of this study was to evaluate zinc and copper status in alopecia areata patients. METHODS: We measured serum levels of zinc and copper in 30 cases of alopecia areata patients and 10 normal individuals by atomic absorption spectrometry. Furthermore, we studied the significance of the ratio between serum levels of the two metals. RESULTS: The serum levels of zinc were significantly lower in alopecia areata patients than in healthy controls. The serum levels of copper were slightly lower in alopecia areata patients than in healthy controls. Ratios of Cu/Zn were slightly higher in alopecia areata patients than in healthy controls. But their differences were not statistically significant. CONCLUSION: We suggest that a serum Zn assay should be included in the chemical assessment of patients with alopecia areata.

BACKGROUND AND OBJECTIVE: Transient global amnesia(TGA) is a neurological syndrome affecting preferentially middle-aged or elderly people and characterized by sudden onset of transient impairment of antegrade amnesia with variably retrograde amnesia. TGA was defined over 30 years ago, but the etiology remain unclear. Several mechanisms have been proposed, including arterial thromboembolic ischemic attacks in both posterior cerebral artery territories, epilepsy, and migraine. Although many studies have reported TGA, only a few reported cerebral perfusion studies using SPECT because of the brief duration of the episode. Technetium-99m-ethyl cysteinate dimmer(ECD) is superior to sensitivity of lesion detection and lesion to normal contrast, probably due to lower back diffusion from the brain to the blood and its excellent radiochemical stability. So we evaluate pathophysiologic mechanism of TGA by using 99mTC-ECD SPECT with or without acetazolamide(ACZ) stress. METHODS: We evaluated six patients with transient global amnesia, four women and two men, age ranges 56 to 78 years, mean 62.2 years. Measurements of CBF and vascular reserve using 99mTC-ECD with or without ACD stress were performed during or after TGA episode. RESULTS: One patient, who was evaluated in TGA episode showed that regional cerebral blood flow was decreased in both anteroinferior frontal, both temporal, right thalamus, both inferior parietal and left parietal region with impaired vascular reserve in left inferior temporal and right thalamus. Others, who were evaluated more than 6days in TGA episode showed that regional cerebral blood flow was decreased in left temporal (4), both temporal region (1), left thalamus (2) and both basal ganglia (1) with preserved vascular reserve except one, showed impaired vascular reserve in left thalamus. CONCLUSION: This result show that severe hypoperfusion of bilateral temporal region and impaired vascular reserve in left temporal region in TGA episode. Other patients who were recovered from TGA showed hypoperfusion of left temporal region and preserved vascular reserve. 99mTc-ECD with acetazolamide SEPCT that sensitively detects localized impaired cerebraovascular reserve should help elucidate these processes. But further study with more cases is necessary for evaluation of pathophysiology of TGA.
