Black adenoma is known to be a rare variant of adrenal cortical adenoma containing characteristic abundant lipofuscin pigments in the cytoplasm. Almost all of them are nonfunctioning and only occasionally they are associated with Cushing's syndrome or primary hyperaldosteronism. We present two cases of black cortical adenoma of the adrenal gland associated with Cushing's syndrome in a 24-year-old woman and a 64-year-old man. This report dealt with clinical and pathologic presentation including ultrastructural identification of lipofuscin pigment.

Meningiomas are usually thought of as firm solid tumors and most standard references make no mention of cystic meningiomas. Although several cases of cystic meningioma have been reported in the literature and their neuroradiological features discussed, the rarity of this entity makes its preoperative diagnosis difficult. Recently, the authors encountered a case of cystic meningioma, which was thought as ependymal cyst or infarction, preoperatively. In this report the authors discussed its clinical, neuroradiological and pathological characteristics with brief reviews of the literature.

BACKGROUND: Serratia marcescens proliferates well in a humid environment or soil and is recently considered as an important pathogen for the severe nosocomial infections. this organism is spreads easily by hand-to-hand transmission, and contaminates medical equipment used for invasive procedures, working environment, medications, and soap. METHODS: We investigated the source of an outbreak of bloodstream infections by S. marcescens isolated that occurred during the period from July to December, 2004, at a university hospital in Gyeonggi Province and attempted to intervene in the outbreak and control it. RESULTS: From July to December, 2004, S. marcescens grew from 296 blood culture from 283 patients. The medical charts of the patients were reviewed, and surveillance cultures were taken to identify the outbreak of nosocomial infections and risk factors. Only four cases of infection were identified and all remaining positive blood cultures were due to contamination. Nine isolates randomly selected from the 296 S. marcescens showed an identical pulsed-field gel electrophoresis pattern. To identify the source of infection, environmental culture and hand cultures of the related medical workers were carried out, but S. marcescens was not isolated. CONCLUSION: As the result of aggressive infection control activities, such as re-education on environmental management methods, hand washing techniques, and blood culture sampling techniques, no more S. marcescens had been grown in blood culture since January, 2005.

A 36-year-old male patient with no remarkable medical history was admitted to our hospital for a health check up. On chest radiography, bilateral aortic notches at the level of aortic arch were shown suggesting aortic arch anomaly without any clinical symptoms. Two aortic arches were almost same-in-size on suprasternal view of transthoracic echocardiography. In addition, multidetector computed tomography showed balanced type double aortic arch forming a complete vascular ring which encircled the trachea and esophagus. The trachea was slightly compressed by the vascular ring whereas the esophagus was intact. Nevertheless, the pulmonary function test was normal. The patient was discharged from hospital with instructions for periodic follow-up.

OBJECTIVES: Clinical features according to the frequency of phototherapy and clinical risk factors on the number of phototherapy were investigated in premature births with gestation <35 weeks and birth weight < or =2,500 g. METHODS: The 186 infants with gestation <35 weeks and birth weight < or =2,500 g were admitted to the neonatal intensive care unit of Kosin University Gospel Hospital from March 2009 to August 2010. The 171 infants were alive and had jaundice requiring phototherapy. Phototherapy was usually started to 50-70% of the maximal bilirubin level. They were divided into two groups according to the frequency of phototherapy as single phototherapy group (group I) and multiple phototherapy group (group II). We retrospectively reviewed the medical records of all patients. RESULTS: The mean gestational age and birth weight of group I were 31.0+/-2.9 weeks and 1,596+/-485 g and those of group II were 31.1+/-2.6 weeks and 1,592+/-430 g. Compared with group I, albumin and Apgar score at 1 minute of group II were significantly higher and the day of peak bilirubin was also late. Duration of phototherapy in group II was statistically longer than that group I but duration of ventilator and aminophylline use for apnea was significantly shorter. The frequency of antibiotic use, incidence of bronchopulmonary dysplasia (BPD), and intraventricular hemorrhage (IVH) of group II were significantly lower than those of group I. CONCLUSIONS: The day of peak bilirubin was late and the frequency of antibiotic use, incidence of BPD, and IVH were low in group II. The aggressive phototherapy may be considered in premature births with jaundice.

The authors report two cases of X-linked juvenile retinoschisis (XLRS) manifested as bilateral vitreous hemorrhage as early as in an 1-month-old infant and in a 3-month-old infant. The one-month-old male infant showed massive bilateral vitreous hemorrhage. During vitrectomy, thin membrane representing an inner part of schisis cavity was excised and intraschisis hemorrhage was evacuated. As intraschisis cavities were cleared, the stump of inner layer appeared as the demarcation line between the outer layer of the schisis retina and non-schisis retina. The other three-month-old male infant presenting with esodeviation also showed bilateral vitreous hemorrhage. Typical bilateral retinoschisis involving maculae could be seen through vitreous hemorrhage in both eyes on fundus examination. Spontaneous absorption of hemorrhage was observed on regular follow-up. XLRS could be manifested as massive hemorrhage inside or outside of the schisis cavity early in infancy.

The Kidd system of blood group is clinically significant since the anti-Kidd antibody can cause immediate or delayed hemolytic transfusion reactions as well as hemolytic disease of newborn (HDN). In contrast to the hemolytic activity of Kidd antibodies in incompatible transfusion, the severity of HDN varies but usually tends to be a benign clinical course with favorable outcomes. And severe HDN due to anti-JKa incompatibility is a rare, which is still not reported in Korea. We experienced a newborn with severe jaundice to be detected within 24 hours from birth due to anti-JKa incompatibility. The laboratory data on admission indicated hemoglobin 13.2 g/dL, reticulocyte 4.08%, total bilirubin 18.7 mg/dL, and direct and indirect antiglobulin tests were positive (2+/2+). But, there are no ABO and Rh (D) incompatibilities between the mother and newborn. Maternal serum was found to contain an antibody that recognized JKa , and also seen in neonate. This patient completely recovered with intensive phototherapy without exchange transfusion. We report this case with a brief review of relevant literature.

BACKGROUND AND OBJECTIVES: Transcatheter device closure becomes the first option for treating secundum atrial septal defect (ASD), but the conventional method is sometimes unsuccessful even when the defect size indicates the closure to be feasible. To increase the success rate, modified methods have been introduced and used. This study aimed to find predictors for using the modified methods in the device closure of secundum ASDs. SUBJECTS AND METHODS: Between October 2010 and December 2012, 92 patients with ASDs underwent the transcatheter device closure. We analyzed the sizes of the defect, the surrounding rims, and the ratios of the left atrium (LA) dimensions to the device size in the patients who underwent the procedure either using the conventional or modified methods. RESULTS: Among the 88 successful cases (95.7%), 22 patients (25%) required modified methods (12 using pulmonary vein and 10 using balloon). The modified method group had the larger size of ASDs and smaller posterosuperior rim. The mean ratios of the LA anteroposterior diameter, width, and length to the device size were all significantly smaller in the modified methods group than in the conventional group (1.20 vs. 1.56, 1.32 vs. 1.71, and 1.61 vs. 2.07, respectively). We found that the risk factors for the modified methods were smaller retroaortic rim, larger ASD, and smaller LA dimension/device size. CONCLUSION: In addition to larger defects and smaller retroaortic rim, the smaller ratios of the LA dimensions to the device size influenced the need for the application of modified methods in the transcatheter device closure of ASDs.
