BACKGROUND: Rapid and accurate identification of methicillin-resistant Staphylococcus (MRSA) is very important for patients because they are one of the most common etiologic agents of hospital infection. Conventional identification methods for MRSA are influenced by various factors such as pH, concentration of salt, conditions of media. METHODS: 53 methicillin resistant staphylococcus strains identified by ATB plus system (Biomerieux, France) were preformed the polymerase chain reaction (PCR), Southern blot hybridization fort the detection of mec A gene, and subcultured in Meuller-Hinton media containing 4 microgram/mL oxacillin for the comparison. RESULTS: The correlation of detection rate of mec A gene PCR and ATB plus systems was 81.6%. The correlation of mec A gene PCR and MRSA on Mueller-Hinton media containing 4 microgram/mL oxacillin was 80%. We confirmed by Southern blot hybridization the amplified mer A gene originated from chromosome of MRSA. As the results of oxacillin sensitivity test, minimal inhibitory concentrations of MRSA were distributed between 40 microgram/mL and 320 microgram/mL. When compared with executing time, ATB plus system took 24 hours, but PCR took 5 hours for identification. CONCLUSION: We concluded that mec A gone PCR techniques were simple and rapid for detection of MRSA comparative to conventional methods.

Dyschromatosis universalis hereditaria is a rare pigmentary disorder initially described in the Japanese literature. The pattern of inheritance is believed to be autosomal dominant, but many sporadic cases have been reported. We encountered a family in which dyschromatosis universalis hereditaria occurred in seventeen members of three generations. In the two members whom we observed, typical skin lesions were distributed all over the body except palrns and soles. By pedigree analysis, we found an autosomal dominant pattern of inheritance. The differential diagnosis of the other reticulate pigmentary disorders is discussed with a review of dyschromatosis reported in the Korean literature.

Two hundred sixty two patients of the essential blepharospasm and hemifacial spasm were treated with Botulinum toxin A (Oculinum(R)). A total of 620 treatments was given injections over a 3-year period. A reduction in spasm intensity was noted in most patients, and the mean response time of the essential blepharospasm and hemifacial spasm were 144.2 days and 172.3 days, respectively, There was no clear relationship between age, sex, toxin dose or preinjected spasm intensity, the amount of spasm reduction, and the mean response time. The mean respone time had no difference from the first through the fourth treatments; but in hemifacial spasm, the mean response time of the second treatment was longer than that of first, third and fourth treatments. The lagophthalmos and superficial punctate keratitis were the most frequent complications. As a result of the injection to avoid the center of the upper and lower eyelids, the frequency of complications could be minimized. There was no clear difference in the beneficial effect and the mcidence of complication (lagophthalmos) between toxin stored in the vaccum and in the non-vaccum state. Patients who were treated with lidocaine mixed toxin had a less effective result than those with saline-mixed toxin.

BACKGROUND: In patients with medial orbital wall fracture, predicting the correlation between the degree of enophthalmos and the extent of fracture is essential for deciding on surgical treatment. We conducted this retrospective study to identify the correlation between the two parameters. METHODS: We quantitatively analyzed the correlation between the area of the bone defect and the degree of enophthalmos on computed tomography scans in 81 patients with medial orbital wall fracture who had been left untreated for more than six months. RESULTS: There was a significant linear positive correlation between the area of the medial orbital wall fracture and the degree of enophthalmos with a formula of E=0.705A+0.061 (E, the degree of enophthalmos; A, the area of bone defect) (Pearson's correlation coefficient, 0.812) (P<0.05). In addition, that there were no cases in which the degree of enophthalmos was greater than 2 mm when the area of the medial orbital wall fracture was smaller than 1.90 cm2. CONCLUSIONS: Our results indicate not only that 2 mm of enophthalmos corresponds to a bone defect area of approximately 2.75 cm2 in patients with medial orbital wall fracture but also that the degree of enophthalmos could be quantitatively predicted based on the area of the bone defect even more than six months after trauma.

Cystinuria is an autosomal recessive inherited defect in renal tubular reabsorption of four amino acids, cystine, ornithine, lysine and arginine. Homozygotes were identified by the formation of urinary tract calculi composed of cystine and by gross hyperexcretion of above mentioned four amino acids. Urinary tract calculi composed primarily of cystine are rare in adults and children. These are usually pure and found exclusively in patients with cystinuria. Herein we report on a 4 and 3/12 years old male child with a right renal stone composed primarily of cystine which was confirmed by chemical analysis method postoperatively. After discharge he has been treated with D-penicillamine, large fluid intake and conversion of urine pH.

Sarcoidosis is a multisystemie disease of unknown cause eharacterized by the formation of noncaseating granulomas that may involve any organ, but the most common sites are the lungs, lyrnph nodes, skin, and eyes. We report a case of sarc ( idosis which may be caused by a foreign body reaction. A 49-year-old women was presented with violet colored, scaly papules on the back and subcutaneous nodules on the left index finger, which had been present for 6 months. A biopsy of a nodule on the left index finger revealed noncaseating epithelioid cell granuloma throughout the dermis with foreign body in the center of the granuloma. Under the polarized light microscopy, tiny particles of foreign material were more obvious. We think that foreign material may actually serve as a nidus for granuloma formation in sarcoidosis.
