Adenocarcinoma of the ciliary epithelium is a rare tumor, usually occuring in elderly patients who have a history of severe ocular trauma or chronic inflammation. We report an adenocarcinoma of the nonpigmented ciliary epithelium found within the phthisical globe of a 36-year-old female whose eye had been loss of vision since infancy. The mass, measured 4.0 x 4.0 cm, was relatively limited by sclera but had invasion to posterior portion. Histologically, the tumor was a compact mass which consisted of tubular and papillary structures with foci of the pleomorphic area. Strands of cells and individual cells were invested with thick basement membrane that have positivity for periodic acid-Schiff stain. Immunohistochemical staining showed strong reactivity for cytokeratin and epithelial membrane antigen, and focal for neuron-specific enolase and S-100 protein.

The clinical and pathological features of warty dyskeratoma are presented. Warty dyskeratoma is a rarely encountered, solitary, benign cutaneous tumor occurring most often on the head and neck and to our knowledge, no cases associated with cutaneous horn have been published in western literature. We experienced a case of warty dyskeratoma with a cutaneous horn occurring in a 70-year-old male, who had a 1.3 cm-sized and slowly growing nodule on his neck. A brief review of the literature, was made especially in relation to the pathological findings and histogenesis of warty dyskeratoma.

The Mainz classification for renal cell tumors was introduced in 1986 and it's utility has been reported in several histogenetic and genetic studies of renal cell tumors. We present a study of 127 cases of renal cell tumors with clinicopathologic correlation, DNA content analysis, and histogenesis studied by histochemical and immunohistochemical staining. The 127 renal cell tumors classified by the Mainz classification were 87 clear cell, 17 chromophilic, 13 chromophobe and 3 sarcomatoid renal cell carcinomas, 5 oncocytomas and 2 adenomas. These subtypes showed significant correlation not with age, sex, Robson's stage, DNA ploidy or tumor recurrence but with nuclear grade (p=0.001) and tumor size (p=0.001). Hall's colloidal iron (p=0.002) and carbonic anhydrase II (p=0.013) stains, representing the origin of distal nephron especially of collecting duct, were significantly correlated with specific subtypes of renal cell tumors, especially chromophobe cell renal carcinoma. This study demonstrates that the Mainz classification suggests several morphologically different subtypes and variants of renal cell tumors and that some of them may have originated from the distal nephron, particularly from the collecting duct.

OBJECTIVES: Obstructive sleep apnea (OSA) syndrome is diagnosed through history, physical examination, imaging studies and polysomnography. Clinical examination of this condition may point to hypertrophic tonsils and crowded oropharynx. The objective of this study is to investigate the usefulness of modified Mallampati grade (MMG) and tonsil grade (TG) in predicting the severity of obstructive sleep apnea. METHODS: MMG and TG were divided into 4 and 5 groups, respectively, according to their severity. Medical records were collected from 94 patients who had received polysomnography and otorhinolaryngologic examination for snoring and sleep apnea at Keimyung University Dongsan Medical Center from March 2002 through April 2004. Patients were divided into two groups according to the apnea-hypopnea index (AHI) : control (n=24), and patients with sleep apnea (n=70). RESULTS: Patients with higher MMG and TG had higher AHI, and MMG and TG proved to have a statistically significant correlation with AHI (p< 0.05) CONCLUSION: MMG and TG were reliable predictors of OSA and helpful parameters in deciding treatment method.

PURPOSE: To obtain the normal standard of the electrocardiogram(ECG) in newborn infants, METHODS: Standard 12-lead ECG recordings of 146 healthy neonates of gestational age above 30 weeks recorded in 24 hours after birth were analyzed for the following parameters: heart rate, QRS axis, PR interval, QTc interval, R and S wave amplitude. RESULTS: The mean gestational age of preterm(between 30 and 37 weeks) and term infants was 33.2 +/-2.4 and 38.4+/-3.2 weeks, and the mean birth weight was 2,168+/-371 g and 3,254+/-436 g, respectively. There was no meaningful difference between two groups in heart rate, PR interval, QTc interval, and QRS axis. Amplitudes of R waves in V1>-V6 leads and S waves in V2, V3 and V5 leads in term baby group were significantly larger than those in preterm baby group. The sum of amplitudes of R and S waves was largest in V2. The amplitude of combined R+S waves in V2 and V3 leads was significantly larger than that in V5 and V6 leads in both groups. This difference was more prominent in tbaby group. CONCLUSION: The results suggest that the increase in cardiac muscular mass and progressive right ventricular predominance are in accordance with the increase in gestational age.

A 44-year-old man was cutting an outer plate of a ship, at a depth of 25 m below sea level. Following a sudden explosion, he was discovered unconscious and was carried to the surface by other divers. There was no evidence of vital signs upon arrival at the hospital. Postmortem computed tomography, which was performed prior to autopsy, revealed massive pneumocephalus in the brain, pneumohemothorax, diffuse lung contusions with multiple traumatic lung cysts, air-fluid level in the cardiac chamber of the chest, and pneumoperitoneum in the abdomen. Postmortem external examination showed a circular abrasion on the jaw, diffuse subcutaneous emphysema, and contusion in the right upper arm. An internal examination revealed intravascular air bubbles in all four chambers of the heart, and diffuse pulmonary trauma including contusion, laceration, and multiple traumatic cysts. Blast injury to the chest, and air embolism due to the underwater explosion were established as the underlying cause of death.
