PURPOSE: Primary bone tumors of hindfoot are uncommon compared with other locations, and there have been few large-group studies. This study was designed to analyze the characteristics and the clinical results of the primary bone tumors of hindfoot. MATERIALS AND METHODS: Forty five cases in 44 patients who have been diagnosed from 1989 to 2011 were reviewed. The minimum follow-up period was 1 year. We retrospectively reviewed the medical records and images. RESULTS: Twenty six cases were male and 18 cases were female. Mean follow-up period was 33.1 months and mean age was 25.1 years. Forty four cases were benign and 1 case was malignant. Thirty six cases occurred in calcaneus and 9 cases were in talus. The most common benign bone tumor was simple bone cyst (20 cases), followed by intraosseous lipoma (12 cases), and chondroblastoma (4 cases). In calcaneus, there were 18 cases of simple bone cyst, and 12 cases of intrasosseous lipoma. In talus, there were 3 cases of chondroblastoma, 2 cases of simple bone cyst, and 2 cases of intraossesous ganglion. Many patients with hindfoot bone tumors presented with pain, but some were found accidentally. Patients received surgical procedures, such as curettage and bone graft, open reduction and internal fixation, tumor resection, and below knee amputation. CONCLUSION: Primary bone tumors of hindfoot are rare and can be misdiagnosed as ankle sprain or contusion. Although most are benign, malignant tumors cannot be ruled out, so early diagnosis and appropriate treatment is important.

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.

We encountered a rare condition of rice body in subacromial and subdeltoid spaces in a patient with unremarkable medical history. Although it is uncommon, there have been continued reports on its formation in certain type of infective and inflammatory arthritis. However, except for a traumatic event, evaluation yielded no known and conceivable cause for his chronic inflammatory bursitis. Relatively typical findings for rice body on magnetic resonance imaging have been described, and in our case the imaging prompted us to schedule early removal, which is generally accepted as the management of choice to prevent further progression of symptoms. The symptoms of the shoulder showed significant improvement, and a close follow-up schedule has been recommended for observation of recurrence and development of any foreseeable underlying cause.

We retrospectively studied the physical and neurological prognoses of 51 small-for-date infants (SFD) who had been taken care in our faculty during the neonatal period. The values of physical measurements of SFD at one and two years of age were both significantly smaller than those of the controlled appropriate-for-date infants. Majority of infants with symmetrical intrauterine growth retardation, whose head circumferences at birth were under -1.5 S. D., showed many complications during the neonatal period, for example; hypoglycemia and polycytemia, and their neurological prognoses were poorer than those with asymmetrical intrauterine growth retardation. To improve these grave prognoses, we stressed the necessity of the system which can provide strict maternal and neonatal care as well as the continuous observation even during the grownup under the co-operation of obstetrician and pediatrician.

The status of DNA synthesis and the effect of UV radiation on the DNA synthesis were studied in mouse skin by microautoradiography. Mice exposed to 100mJ/cm of UVB were injected intradermally with tritiated thymidine, 5 minutes, 2, 6 and 24 hours after irradiation and biopsies were processed for light microscopic autoradiography, A total of 25 ICR female albino haired mice were used as subjects. We compared heavily labeled cells(>10 grains/nucleus) and sparsely labeled cells (3-10 grains/nucleus) in UVL irradiated skin with nonirradiated control skin. 1. Within 5 minutes after UVL exposure an apparent depression in the number of heavily labeled cells occurred. This reduction was statistically significant and remained so for at least six hours post,irradiation. By 24 hours after UVL exposure, the reduction was recovered to nearly control level. 2. By five minutes after UVL exposure, sparsely labeled cells were observed in basal cell layer and differentiated cell layer. The nurriber of sparsely labeled cells appeared highest at five minutes after UVL exposure and then tended to fall to nearly control level at 24 hours. This aberrant type of TdR H incorporation is thought to represent unscheduled DNA synthesis to repair pyrimidine dimers formed in UVL injured DNA molecules,

The authors analysed 196 cases of convulsive disorder in children who were admitted to the pediatric department of Kyunghee Hospital from June 1993. Blood samples were drawn immediately following seizures on arrival. Serum prolactin values were measured by radioimmunoassay. The results obtained were as follows: 1) Mean serum prolactin value was 55.4+/-20.8ng/ml in generalized seizures within 1 hr following seizures, 22.5+/-3.9ng/ml in partial seizures. There was a significant difference between generalized scizures and partial scizures (p<0.05). 2) Mean serum prolactin value was 23.5+/-9.7ng/ml in generalized seizures within 1~3 hrs following seizures, 10.4+/-4.9ng/ml in partial seizures. There was a significant difference between generalized seizures and partial seizures (p<0.05). 3) Mean serum prolactin value was 9.5+/-4.4ng/ml in generalized seizures 3 hrs following seizures, 9.8+/-4.8ng/ml in partial seizures. There was no significant difference between generalized seizures and partial seizures (p>0.05). We found transient hyperprolactinemia following generalized seizures but a little change following gartial seizures. Postictal elevation of serum prolactin may represent a biochemical marker of generalized and partial seizures.
