We report a case of a tumor of the follicular infundibulum in a 54-year-old woman who had a papule on the medial side of the right upper eyelid for four months. Histopathologic findings were characterized by proliferation of follicular infundibular epithelium in the form of a thin subepidermal plate and small hair follicles in the tumor plate.

Background ; Carbon Monoxide is colorless, ordorless, highly toxic gas produced by fire and by motor vehicles and appliances which use carbon-based fuels. In Korea, since coals were the main domestic fuel for cooking and for heating the floor, many cases of carbon monoxide intoxication have occurred annually. Until now, systemic complications & clinical manifestations as well as neurologic complications following carbon monoxide poisoning have rarely been reported. METHODS: I have researched systemic complications and clinical manifestations including neurologic complications from 1986 to 1997. I reviewed retrospectively medical records of 188 admitted patients to the Yonsei Medical Center due to carbon monoxide intoxication, and analyzed them according to the neurological, cardiovascular, respiratory, urogenital, dermatological and other systems. RESULTS: 1)The number of the admitted patients due to CO intoxication to Yonsei Medical Center between 1986 and 1997 has decreased compared to that between 1976 and 1981. 2)In this study, the cause of CO intoxication were furnaces in 170 cases(93.9%), fire accidents in 2 cases(1.1%), gas boilers in 2 cases(1.1%), LPG gas in 1 case(0.55%) and propan gas in 1 case(0.55%) in order. 3)Systemic complications and clinical manifestations after CO intoxication were 167(88.8%) nervous , 59(31.4%) musculoskeletal, 56(29.8%) respiratory, 49(26%) dermatologic, 44(23.4%) cardiovascular, 30(16.0%) genitourinary and 9(4.8%) other complications. Other systemic complications as well as neurological complications were not rare. 4)The clinical manifestations of neurological complications were decreased mental status(drowsy in 57 cases(30.3%), stupor in 63 cases(33.5%), semicoma in 33 cases(17.6%), coma in 13 cases(6.9%), alert in 22 cases(11.7%), focal sign related to the stroke in 16 cases (7.4%), incontinence in 22 cases(11.7%), seizure in 4 cases(2.4%), psychiatric behavior in 4 cases(2.4%), peripheral neuropathy in 4 cases(2.4%), bracheal plexopathy in 4 cases(2.4%), and torticollis in 1 case(0.5%). Delayed neurologic sequelae were akinetic mutism in 13 cases(76.5%), mental deterioration in 6 cases(35.3%), incontinence in 6 cases(35.3%), psychiatric behavior in 3 cases(17.6%), speech disturbance in 2 cases(11.8%), involuntary movement in 2 cases(11.8%), and depression in 1 case(5.9%) in order. 5)Cardiovascular complications showed tachycardia in 47 cases(28.3%), ischemic heart disease in 34 cases(18.6%), right bundle branch block in 6 cases(3.6%), left axis deviation in 4 cases(2.4%), atrial fibrillation in 3 cases(1.8%), sinus arrhythmia in 2 cases(1.2%), premature atrial contraction in 1 case(0.6%), premature ventricular contraction in 1 case(0.6%), primary atrio-ventricular block in 1 case(0.6%), prolonged QT in 1 case(0.6%). 6)Pulmonary complications were pneumonia in 23 cases(13.1%), pulmonary edema in 22 cases(12.6%), pneumonia with pulmonary edema in 3 cases(1.7%), and atelectasis, pulmonary hemorrhage, empyema, pleurisy in each 1 case(0.6%). 7)Azotemias were 26 cases(14.2%), clinically confirmed acute renal failures were 4 cases(2%) 8)Rhabdomyolysis was not rare as 63 cases(33.5%) compared to the previous report. 9)Dermatologic complications were erythema with bullae in 21 cases(11.9%), erythema without bullae in 14 cases(7.9%), bullae only in 10 cases(5.6%), laceration in 3 cases(1.65%), and ulceration in 1 case(0.55%). Conclusion ; We must consider other systemic manifestations as well as neurological symptoms in patients with CO intoxication since those are not infrequent in Korea.

The advent of the global pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) necessitates a thorough study of the stability and transmissibility in the environment. We characterized the stability of SARS-CoV-2 in three water matrices: fresh, tap, and seawater. The minimum infective dose of SARS-CoV-2 in Vero cells was confirmed to be 10 3 PFU/mL. The stability of SARS-CoV-2 varied according to the water matrix: infective SARSCoV-2 was undetectable after treatment with fresh water and seawater, but remained detectable for 2 days in tap water, when starting with an initial concentration of 10 4 PFU/mL. When the starting concentration was increased to 10 5 PFU/mL, a similar trend was observed. In addition, viral RNA persisted longer than infectious virus in all water matrices. This study was conducted in stagnant water containing a significantly high titer of virus, thus, human-to-human transmission of SARS-CoV-2 through the actual aquatic environment is expected to be rare.

The peritoneal equilibration test(PET) has been recommended in adults as a standardized means of estimating solute transport. However, it appears that norrns for pediatric PD patients may be different. We performed a PET on 16 children aged 3 to 18 years using a dwell volume for 30ml/kg of 2.596 dialysate. Our children transported glucose more rapidly than adults, however, creatinine transport was not significantly different. Age did not correlate with D/13% glucose or drainage volume. There was negative correlation between D/D% glucose and D/P Cr. There was no significant difference between initial and maintenance CAPD patients. There was slight difference in patients with previous peritonitis. In conclusion, there was difference in glucose transport between children and adults.

OBJECTIVE: The aim was to assess the value of resistance index(RI) and pulsatility index(PI) to differentiate between benign and malignant ovarian tumors by color and pulsed Doppler ultrasound. METHODS: 129 ovarian tumors identified with ultrasound were referred for color and pulsed Doppler ultrasound evaluation to calculate the lowest RI and PI, and the corresponding histopathologic diagnosis was recorded. RESULTS: The intratumor artery waveforms were obtained in 37.1%(36 of 97) of benign tumors and in 91.0%(29 of 32) of the malignant group. RI and PI were lower in malignant tumors than in benign tumors(p<0.01). Also, there was a significant incremental decrease in both indices value from the benign tumor toward borderline malignancy(p<0.05) and to invasive ovarian cancer(p<0.01). But, there was no significant difference in both indices value according to the FIGO stage of ovarian malignancy. For RI cut-off value of 0.6, sensitivity and specificity were 89.7% and 91.7%; for PI cut-off value of 1.1, 86.2% and 91.7%. Therefore, the most accurate cut-off values of RI and PI were 0.6 and 1.1, respectively. CONCLUSION: RI and PI calculated by color and pulsed Doppler ultrasound can help in the diagnosis and selection of treatment plan of ovarian tumors, especially when the morphological finding of ovarian tumor is equivocal. And during the follow up of benign tumors, both indicies can give us the clue of malignant potential of benign tumors.
