We report a case of pityriasis rotunda occurring in a patient with pancreatic adenocarcinoma. The patient was a 64-year old female who had a pancreatic adenocarcinoma. The skin lesions were asymptomatic, multiple, various sized (1 to 15cm in diameter), isolated or confluent and finely scaly light brownish to grayish colored patches on the lower abdomen, back and thigh. Histopathologic findings shawed mild hyperkeratosis, atrophy, loss of granular layer, increased melanin pigments in basal layer of the epidermis and mild perivascular monocytic infiltration in the upper dermis.

BACKGROUND: Ketamine use in emergency room has been increased. It has rapid onset of action and appropriate duration of action. It does not need endotracheal intubation and produces potent analgesia, sedation, and amnesia. The object of this study is to determine the safety and the degree of physician's satisfaction in relation to ketamine use. MATERIALS AND METHODS: This is a prospective study using protocol. Pediatric trauma patients who need sedation were given IM ketamine(4mg/kg) and atropine(0.01mg/kg) in a same syringe. Monitoring of patients was done by EM residents and complications of ketamine use were recorded. Physician's satisfaction was also recorded after the procedure. RESULTS: Intramuscular ketamine was administered 54 times, mainly for laceration repair. Physicians completed protocol for 51 of treated children. The median time for onset of sedation was 6.5+/-2.4 min, and duration of action was 32.4+/-10.8 min. Hypersalivation occurred in 9.8%(n=5); random movement 3.9%(n=2), emesis during procedure(n=1), emesis at home(n=1), and transient oxygen desaturation(n=1). All were quickly identified and treated without specific airway management and sequelae. Of 84% of physicians was satisfied with ketamine use for pediatric sedation. CONCLUSION: Intramuscular ketamine can be administered safely and satisfactorily in emergency room to facilitate pediatric procedures in conjunction with a defined protocol and appropriate monitoring.

BACKGROUND: Surfactant protein C(SP-C) is a hydrophobic 5,000 dalton molecule. SP-C has the primary roles in accelerating surface spreading of a surfactant phospholipid. The filter hypbridization and solution hybridization assays are both rapid and sensitive and can be used to measure the RNAs complementary to any cloned DNA sequence. METHODS: The authors measured the SP-C mRNA levels quantitatively using solution hybridization and filter hybridization assays to obtain a standard curve equation to quantify the mRNA of unknown samples comparatively. RESULTS: 1. The minimum level of the specimens by solution hybridization was 3 pg for SP-C mRNA. 2. The standard curve equation of the solution hybridization assay between the counts per minute(Y) and the SP-C mRNA transcript input(X) was Y=6.46 X+244. The correlation coefficient was 0.9. 3. The minimum detection level of specimens by filter hybridization was 0.1 ng for SP-C mRNA. 4. The standard curve equation of the filter hybridization assay between the counts per minute(Y) and SP-C mRNA transcript input(X) is Y=2541.6 X+252.7. The correlation coefficient was 0.99. CONCLUSION: A comparison of CPM/filter in the linear range allowed an accurate and reproducible estimation of the SP-C mRNA copy number. Filter hybridization and solution hybridization assays are both rapid and sensitive and can be used to measure the RNAs complementary to any cloned DNA sequence. It is ideally suited to situations where accurate quantitation of multiple samples is required.

Many agents for the treatment of osteoporosis are broadly classified as inhibitors of bone resorption and stimulators of bone formation. Many pharmacological derivatives of bisphosphonates are used in the treatment of osteoporosis by inhibiting osteoclast-mediated bone resorption. Although the pamidronate, derivative of bisphosphonates, has a potent antiresorptive activity, there are only a low reports about prevention and treatment of postmenopausal osteoporosis using it. The purpose of this study is to evaluate the changes of bone metabolism and bone mass after pamidronate administration during the early period of estrogen deficiency. Ninty-five Sprague-Dawley rats (weight 233-243 g) were divided into 3 groups. Group 1(n=28) was performed sham operation. Group 2 (n=25) was both ovariectomized and intravenously injected with 0.5 cc normal saline. Group 3 (n=42) was both ovariectomized and intravenously injected with 0.1 mg/kg pamidronate. During the first 8 weeks normal saline or pamidronate was intravenously injected twice a week(q 3 day or q 4 days). After 4 weeks of observation without injection the experiental animals were sacrificed at postoperative 12 weeks. There were statistically significant decrease in the body weight and the weight of uterus in group 1 compared with group 2, 3. There was statistically significant decrease in the bone mass of the spine, proximal femur, proximal tibia in the group 2 compared with group 1, 3. The difference of bone mass between group 1 and 3 was statistically insignificant. Serum osteocalcin and PICP concentration were significantly increased in group 2 and 3 compared with group 1. But there was no statistical significance between group 2 and 3 in serum osteocalcin and PICP concentration. Serum ICTP concentration was significantly decreased in group 1 and 3 compared with group 2, but the difference between group 1 and 3 was insignificant. These results suggests that the administration of the pamidronate during the early period of estrogen deficiency can inhibit bone resorption and prevent trabecular bone loss of the spine, proximal femur and proximal tibia metabolically.

Septo-optic dysplasia, as first described by de Morsier, is a rare developmental anomaly of absent or hypoplastic septum pellucidum, a primitive optic vesicle, and dysplasia of the optic nerve, chiasm, and optic tracts. It is a common cause of hypopituitarism in children and has variable hypothalamic-pituitary dysfunction. We experienced a case of septo-optic dysplasia in 5 month old female baby who presented with developmental delay and seizure. A magnetic resonance imaging of the brain showed absence of the septum pellucidum and the fundoscopic examination disclosed the absence of left optic disc and atrophy of right optic disc.

The choroid plexus papillomas are uncommon neoplasms of the central nervous system, and constitute 0.5~0.6 percent of intracranial tumors. These tumor are surgically treatable and the encouraging results of surgical removal justify an aggeressive surgical approach. We present a case of lateral ventricle choroid plexus papilloma in a child with communicating hydrocephalus.
