BACKGROUND: The verse transcriptase polymerase chain reaction (RT-PCR) has been widely used to analyze the bcr/abl fusion mRNA in chronic myelogenous leukemia (CML). Fresh or cryopreserved cells may not always be available for molecular diagnosis. So we investigated the value of stored bone marrow aspirate smears as the sources of material for the detection of bcr/abl mRNA. METHODS: We extracted RNA using modified Chomczynski method, and amplified bcr/abl mRNA by RT-PCR from the 70 cases of bone marrow smear slides stored from 7 days to 7 years, which were comprised of 49 CML, 11 other chronic myeloproliferative disorders (CMPD) and 10 acute lymphoblastic leukemia (ALL). Sensitivity of RT-PGR was tested using the slide smears prepared with 10(0)-10(6) K562 cells, and RT-PCR results losing each fresh bone marrow cellular suspension and slide smears in 24 patients were compacted. For major bcr/abl rearrangement, RT-PCR was performed by nested PGR afters GDNA synthesis losing downward primer and beta2-microglobulin was used as RNA controls. RESULTS: The sensitivity of RT-PCR for detecting bcr/abl mRNA was l02 cells per slide. Sixty one cases (86%) of 70 bone marrow aspirate smears showed positive results of beta2-micyoglobulin cDNA as an indicator of intact RNA. Thirty nine cases of 42 beta2-microglobulin cDNA positive CML bone marrow aspirate smears showed 29 b3a2 type mRNA and 10 b2a2 type mRNA. Nine cases of 11 bone marrow aspirate smear with other CMPD showed negative results of bcr/abl mRNA. Two cases of 10 ALL bone mallow aspirate smears had b2a2 type mRNA and b3a2 type mRNA, respectively. The results for detection of bcr/abl mRNA with fresh cell suspensions of 24 patients were same as the bone marrow aspirate smears storied for 7 days to 1 year. CONCLUSIONS: These data indicated that RNA obtained from bone marrow smears storied for less than 1 year was valuable as the source of RT-PGR for the detection of bcr/abl mRNA in CML and the bone marrow smears stored for much longer period ould be assailable as the specimens for retrospective analysis of specific gene alter-ation in other hematologic malignancy.

Salmonella osteomyelitis is uncommon and it often develops in patients with sickle cell anemia and other hemoglobinopathy. Especially, osteomyelitis caused Salmonella typhi in a nonsickle cell patients is a very rare event. We report three cases with review of literature.

BACKGROUND: The growth of elderly population increased the need for oral health care. Elderly patients with poor teeth alignment needs more attention with orthodontic treatment METHODS: Elderly patients visiting department of orthodontics, Kangdong Sacred Heart Hospital between 2000-2004 were treated with fixed appliances in one or both dental arches. Treatment plans were different from than that of younger patients and included uncommon and strategic removals of teeth and prosthesis. RESULTS: There was decrease in orthodontic treatment forces with increasing age, and the observation made from this study was favorable in the patients' as well as in the orthodontist's, point of view. It was possible to move the remaining teeth considerably, and the retention was made with various fixed appliances. CONCLUSIONS: Orthodontic treatment is not limited by patient age. However, it is wise not to extend treatment goals too far beyond the patients' objective needs

Retinal toxicity secondary to intravitreal injection of gentamicin for the purpose of prophylaxis or treatment of endophthalmitis was reported infrequently and it was thought to be caused by an error in the intravitreal injection technique or by faulty dilution of gentamicin. After vitrecotomy, we experienced two cases of ischemic retinopathy secondary to intravitreal injection of gentamicin for prevention of endopthalmitist.

We have applied the intraoperative use of Perfluorophenanthrene (C14F24) liquid in 19 eyes of complicated retinal detachment surgery in 19 patients since November 1990 to October 1991. The vast majority of case of retinal detachment was trauma (9 eyes) and uveitis including pars planitis (6 eyes) remainders were juvenile retinoschisis, cataract surgery, myopIa, diabetes one eye each. The grade-D of proliferative change was found in 9 eyes (D1 3 eyes, D2 3 eyes, D3 3 eyes) and 8 eyes belong to over grade-C2 (C2 4 eyes, C3 4 eyes). Multiple anterior retinal tears were found in two. Giant retinal tear was noticed in 5 eyes and the other one was made on therapeutic purpose. Intraoperative reattachment was obtained in all eyes. The follow-up periods were 6 or more (mean 9.1) months. At last follow-up, the retina was attached in 12 eyes (63%), partially attached in 2 (10%) and redetached in 5 (26%). Visual acuity was improved or same in 12 eyes (63%), became worse in 7(37%). Visual acuity of 0.02 or better was obtained in 12(63%) eyes and 3(16%) saw 0.1 or better. Perfluorophenanthrene liquid was thought as non-toxic, heavy biomaterial and effective to treat the complicated retinal detachments.

6.Application of a Silicone Sheet in Negative-Pressure Wound Therapy to Treat an Abdominal Wall Defect after Necrotizing Fasciitis.
Archives of Plastic Surgery 2017;44(1):76-79
Necrotizing fasciitis (NF) is an aggressive soft-tissue infection involving the deep fascia and is characterized by extensive deterioration of the surrounding tissue. Immediate diagnosis and intensive treatment, including debridement and systemic antibiotics, represent the most important factors influencing the survival of NF patients. In this report, we present a case of NF in the abdomen due to an infection caused by a perforated small bowel after abdominal liposuction. It was successfully treated using negative-pressure wound therapy, in which a silicone sheet functioned as a barrier between the sponge and internal organs to protect the small bowel.

Gold preparation had been used frequently in the past in the treatment of rheumatoid arthritis, tuberculosis and lupus erythematosua, etc. It is still used. when other more potent remedies, such as steroid, failed. We report a case of drug eruption following the use of gold preparation. A 38 year-old female was referred to our department from orthopedic surgery because of generalized, multiple, pin head sized, violaceous and flat topped papules of 1 x 2 mm in size and mucosal erosions and ulcers following gold therapy for rheumatoid arthritis. She had received 5 intramuscular injections of gold preparation (Myochrysine'), 220mg in total amounts. Our clinical impression was lichen planus like drug eruption, but histopathological picture disclosed nonapecific dermatitis. The eruption had disappeared gradually following oral administration of antihistaminics and prednisolone and daily starch tub baths.

Mid-arm circumference and mid-arm circumference/head circumference ratio(MAC/HC) were measured in 207 AGA(appropriate for gestational age) infants delivered at 26 to 42 weeks of gestation from January 1990 to December 1993 in Yeungnam University Hospital, Taegu, Korea. There were linear relationships between MACs and MAC/HC ratios and gestational age(MAC : y=03181x -2.2069, r=0.81, p<0.001 ; MAC/HC ratio : y=0.049x+0.1128, r=0.62, ; < 0.001). Using standard curves of MAC and MAC/HC ratio according to the gestational age, measurement of MAC or MAC/HC ratio can be a noninvasive, simple method to evaluate the intrauterine growth of newborn infants and the nutritional status of growing premature infants.
