Ectopic lacrimal gland denotes a lacrimal gland which is located anywhere other than its normal site, lacrimal fossa, and it can occur in places like conjunctiva, cornea, lid, nasal mucosa, and orbit. It is a rare congenital anomaly and needs to be differentiated form other tumors. The literature contains few reports of ectopic lacrimal gland. We experienced a case of a 28-year-old Korean man who presented with an ectopic lacrimal gland with duct at temporal aspect of bulbar conjunctiva. The glandular tissue was excised and was histopathologically confirmed as such. We report it with reviews of the literature concerned.

Amblyopia and strabismus are common in eyes of prematurity and the need for early detection of amblyopia and amblyogenic factors is widely recognized. So, we performed refraction in premature infants at the 6 months of age to evaluate the incidence and degree of myopia and the changes of refractive errors according to the development, disease course and photocoagulation therapy of retinopathy of prematurity[ROP]. It is the purpose of this study to evaluate the effectiveness of MTI[medical Technology, Inc]photoscreener by comparing the sensitivity and specificity between refractive errors determined by manifest photorefraction and cycloplegic photorefraction in 6-month-old premature infants in Sung-Ae General Hospital. Pass or fail screening data from photograph of 32 non-dilated and dilated premature infant were calculated by two masked observers, compared with the results of cycloplegic retinoscopy, and the statical analysis was carried out. In the cases of cycloplegic photorefraction, Ten eyes of myopia, 4 eyes of emetropia, and 50 eyes of hyperopia were found, and 21 eyes of astigmatism above 1.5D were also detected. Overall statistical analysis of sensitivity and specificity rate were 71.7% and 69.5%in manifest photorefraction, 87.5% and of 75%in cycloplegic photorefraction, respectively. In non-cycloplegic photorefraction, sensitivity of myopia and hyperopia were 92.8%, 65%, but in cycloplegic photorefraction, sensitivity of myopia and hyperopia were 75%, 100%, respectively. The outcomes of our study suggest that MTI photoscreener in cycloplegic photorefraction was more reliable than non-cycloplegic photorefraction. Myopia under 1D turned to hyperopia in cycloplegic photorefraction, so the sensitivity of that was not to be reliable, but the sensitivity of hyperopia was high. Thus, the authors can readily recommand this cycloplegic photorefraction in uncooperable infants to evalute the refractive error conveniently.

Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.

BACKGROUND: In order to understand the pathogenetic mechanism of sepsis-induced acute lung injury, inhibition of phospholipase A2 (PLA A2) was carried out in an endotoxin-induced septic lung model. METHODS: Sprague-Dawley rats were divided three groups; sham group, endotoxin group (instillation of E coli endotoxin, 100microgram/rat, type 017) and mepacrine group (the non-specific PLA2 inhibitor, 50 ml/kg intraperitoneal injection after endotoxin treatment). Five hours after endotoxin treatment, protein contents, neurophils counts, gamma-glutamyl transpeptidase (GGT) activity and surfactant concentrations in the bronchoalveolar fluid (BAL), meyloperoxidase (MPO) and PLA2 activity in the lung were measured. A morphological study for the effect of the endotoxin and mepacirne, and a cytochemical electron microscopy for detection of hydrogen peroxide in the lung were also performed. RESULTS: Endotoxin increased the concentrations of protein, the number of neutrophils, and GGT activity in the BAL fluid, MPO and PLA2 activity in the lung but mepacrine decreased these parameters (P < 0.001). The light density of surfactant was increased by the endotoxin (P < 0.001), but mepacrine diminished this pathological change. In the light microscopic findings, the endotoxin caused pulmonary accumulation of neutrophils, atelectasis and transudation of intravascular protein was observed. In contrast, mepacrine lessened these pathological findings. In ultrastructural findings, adhesion of neutrophils to endothelial cells, necroses of type II cells and endothelial cells, and the damage of lamellar bodies were observed after the endotoxin treatment, which recovered with mepacrine. In the cytochemical electron microscopy for detection of hydrogen peroxide in the lung, the deposits of cerrous perhydroxide were increased by the endotoxin but mepacrine decreased deposits of cerrous perhydroxide. CONCLUSIONS: Inhibition of PLA2 in an endotoxin induced acute lung leak showed protection against oxidative stress by a diminution of neutrophilic respiratory bursts and a decreased production of free radicals. It is suggested that PLA2 has a pivotal role in causing acute oxidative stress in endotoxin induced acute lung injury.

Capsule contraction syndrome is severe constriction of the anterior capsular opening and equatorial capsular bag diameter after extracapsular cataract surgery. It is relatively common in patients with continuous curvilinear capsulorhexis, but rarely in can-opener capsulotomy or anterior radial capsular tears. It is due to capsular bag contraction from fibrous dysplasia of residual lens epithelial cells with weakened zonular resistance. We experienced a case of capsule contraction syndrome in a 72-year old woman with retinitis pigmentosa, who had phacoemulsification following an intact 5.0mm-continuous curvilinear capsulorhexis 4 months before. After successful YAG laser radial anterior relaxing capsulotomy, her visual acuity restored to 0.3, limited by cystoid macular edema.

Iatrogenic Cushings syndrome is caused by administration of systemic steroids for some disorders, and is clinically characterized by truncal obesity, hypertension, fatigability, amenorrhea, hirsutism, abdominal striae, edema, glucosuria and osteoporosis. We report herein a case of iatrogenic Cushings syndrome in the treatment of atopic dermatitis. The patient, a 32-year-old male, had been diagnosed with atopic dermatitis and was intermittently treated with topical and systemic steroids for 12 years. He revealed facial edema, truncal obesity and striae distensae in both the axilla and abdomen. Steroids are one of the important agents in the treatment of atopic dermatitis but care must be taken in their administration.

We observed a 55-year-old man who had granuloma pyogenicum on the medial border of the right fifth toe which developed after scratching of the wound. Histopathological findings showed many newly formed capillaries that had prominant endothelial cells and showed varying degrees of dilation without appearance of epidermal collarette signs. We tried intralesional treatment with triamcinolone acetonide (10mg%, 1/week*3). After 3 sessions of treatment, the lesion dramatically regressed nearly to normal size.

Ecthyma Gangrenosum is a rapidly progressing skin infection charact,erized by edema, hemorragic bullae and necrosis. Ecthyma Gangrenosum occurs almost exclusively in severely imrnunocompromised patients during the course of pseudomanas aeruginosa septisemia. A 5 month-old boy was transferred to our department because of multiple well defined central necrotic black-colored large erythematous bullae. In the bacterial cultures of skin, stool and liver aspiration fluid, Pseudomonas aeruginosa was grown. In the abdominal ultrasonogram and computed tomogram, the multiple liver abscess, hepatomegaly and ascites were shown on both hepatic lobes. Herein we report a case of ecthyma gangrenosum associated with liver abscess.

PURPOSE: To report a case of a young man with nonspecific normal retinal vessels found in foveal avascular zone. METHODS: We experienced a 20-year-old man with decreased visual acuity of left eye. In anterior segment there was no abnormality, but there were unusual vessels in foveal avascular zone that appeared to be normal vessels. RESULTS: In fluorescein angiography, dye was exhibited on the vessel of foveal avascular zone in 14-15 sec after injection, and there were no leaking or abnormal findings. CONCLUSIONS: Normal retinal vasculature in foveal avascular zone is known to be an extremely unusual case in normal adult, and it is to report a case with review of available papers.
