The amniotic band syndrome is a collection of congenital deformities presurmably due to rupture of amniotic sac. It appears to cause fetal injury through three basic mechanisms including malformation, disruption, and deformation. The associated anomalies vary firom minor digital defect to major craniofacial and visceral defects. They can be categorized as neural tube-like defects, craniofacial anomalies, limb anomalies, abdominal and thoracic wall defects, visceral anomalies, and constriction bands. We had expericnced a case of severe congenital craniofacial anomaly due to amniotic bands diagnosed by ultrasonogram in the antenatal period is presented with a brief review of the literatures.

The authors retrospectively analysed the ultrasonographic findings of 43 cases of surgically confirmed hypertrophic pyloric stenosis and their postoperative findings of sonograms taken at 1 month(n=40) or 3 months( n=5) after pyloromyotomy. In preoperative study, the thickened pyloric muscle was isoechoic or slight hypoechoic relative to liver on the midline longitudinal view and appeared as a "nonuniform acoustic ring" on the transverse view. The results of measurement in the all cases with hypertrophic pyloric stenosis were the pyloric thickness ≥3.8mm, the pyloric diameter ≥14mm, the pyloric channel length ≥16mm, the pyloric muscle volume ≥2.21Cm

PURPOSE: This study was to determine the relationship between age and the mandibular cortical bone thickness on panoramic radiograph. MATERIALS AND METHODS: Panoramic radiographs of 360 patients (180 men and 180 women) over 20 years old, who visited the Chonbuk National University Hospital from January to December in 2007, were assessed. The subjects were divided into 5 age groups. Five indices such as cortical bone thickness at the gonion (GI), antegonion (AI), and below the mental foramen (MI), the panoramic mandibular index (PMI), the mandibular cortical index (MCI) were measured on panoramic radiographs. RESULTS: All five indices including GI, AI, MI, PMI, and MCI showed significant differences between third decade and over 8 decade groups (p<0.05). PMI, MI and GI showed significant differences with gender statistically (p<0.05). CONCLUSION: The mandibular cortical bone thickness showed negative correlation with age, and the value of the thickness (PMI, MI, and GI) was greater in men than in women.

Subclavian steal syndrome caused by an acute thrombus is very rare. We present a case of cerebellar infarction with proximal subclavian artery thrombosis. A 56-year-old woman was admitted for sudden vertigo. One day prior to admission, she received a shoulder massage comprised of chiropractic manipulation. On examination, her left hand was pale and radial pulses were absent. Blood pressure was weak in the left arm. Downbeat nystagmus and a right falling tendency were observed. Brain MRI showed multiple acute infarctions in the left cerebellum. The findings of Doppler ultrasonography in the left vertebral artery were compatible with a partial subclavian artery steal phenomenon. Digital subtraction angiography demonstrated a large thrombus in the left subclavian artery. After heparin infusion, thrombus size markedly decreased. Cerebellar infarction caused by acute subclavian thrombosis following minor trauma is rare, but the thrombus can be successfully resolved with anticoagulation.

PURPOSE: We analyzed the oncologic outcome of the malignant transformed benign giant cell tumor of bone. MATERIALS AND METHODS: Between January 2000 and February 2012, 5 cases were referred with suspicious malignant transformation of benign giant cell tumor. No patients underwent radiation therapy. RESULTS: After referral, all patients received the wide excision of the tumor and its' pathologic diagnosis were osteosarcoma. As classified by the location of tumor lesion, 3 cases were located in the distal femur, 1 case was in the distal radius and 1 case was in the proximal femur. The average latent period between diagnosis of benign giant cell tumor and diagnosis of secondary malignant giant cell tumor was 49.2 months. (range, 24-126 months) The mean follow-up period was 21.6 months. There were subsequent local recurrence in 2 cases and 3 patients developed distant metastasis. All patients with lung metastasis were dead. CONCLUSION: Malignant transformation of benign giant cell tumor of bone can be occurred within 5 years. Therefore, when benign giant cell tumor suspicious malignant transformation, it is necessary to do more aggressive treatment.

Isolated left brachiocephalic artery with right aortic arch is extremely rare congenital anormaly. This malformation can cause subclavian steal phenomenon. We report the duplex sonographic and conventional angiographic findings of isolated left brachiocephalic artery in a 22-year-old female presented with dizziness.

In solid tumor, there is a hypoxic region where oxygen supply is insufficient. In this study, we found that one of the quinolone antibiotics, levofloxacin, made a human ovarian cancer cells, SK-OV-3, resistant to hypoxia, even in the presence of a platinum-based anti-cancer therapeutic, carboplatin; when the cells (2 X 10(5) cells/12 well multi culture dish) were grown in no glucose medium (0 g/l) under hypoxia (1% O2), all the cells became dead after 24 hours of culture in the absence of levofloxacin and carboplatin, whereas the cells still survived, at least, until 36 hours of culture in the presence of levofloxacin (10-100 microgram/ml) alone or in combination with carboplatin. The results might have some implications in treating solid tumor; if cancer patients should be treated for infection with antibiotics, quinolone antibiotics can aggravate tumor by making cancer cells more resistant to hypoxia. This is also true even when a patient is treated with carboplatin. Therefore, the results strongly suggest that we should be careful in choosing antibiotics when they are used for cancer patients. In this regard, our work could be a new guideline in choosing antibiotics when antibiotics are applied for treating cancer patients.

Burkholderia cepacia is a highly virulent pathogen known to cause opportunistic infections in immunocompromised patients. It accelerates lung disease and causes necrotizing pneumonia with associated severe sepsis, known as cepacia syndrome. In particular, lung transplant recipients infected with Burkholderia cepacia show higher mortality after lung transplantation than those who are not infected with this organism. Due to broad-spectrum antibiotic resistance, a combination therapy should be used according to the results of the susceptibility test. This bacterial infection is rare in Korea, and no case was reported in lung transplant recipients. However, we report a case of pneumonia caused by Burkholderia cepacia after lung transplantation. As Burkholderia cepacia was grown from a sputum culture, the patient was treated initially with a combination of meropenem and trimethoprim/sulfamethoxazole and then ceftazidime and trimethoprim/sulfamethoxazole as a result of leukopenia. After antibiotics treatment for 20 days, sputum cultures became negative for Burkholderia cepacia and the patient successfully recovered.

BACKGROUND: The cerebral blood flow velocity (CBFV) and rate pressure product (RPP) have been reported to benefit hemodynamics more during exercise in the recumbent position than during that in the upright position. However, it is unclear which angle is of the greatest benefit to hemodynamics during exercise in the recumbent position. This study aimed to evaluate the effect of the recumbent angle on CBFV and RPP during exercise. METHODS: In a balanced crossover study, 15 healthy volunteers (age, 18.7±1.1 years) were asked to perform the bicycle exercise four times in the upright and at recumbent angles of 67° (R), 47°R, and 15°R, with weekly intervals between each condition. The exercise intensity was set initially at 50 W and increased by 25 W every 2 minutes up to 150 W. CBFV in the middle cerebral artery (MCA) was measured using transcranial doppler sonography. All data were analyzed using two-way repeated-measures analysis of variance. RESULTS: CBFV at 15°R was significantly higher than that in the upright position and at 67°R at 10 minutes recovery (69±16 vs. 56±7 and 58±10 cm/s, respectively; P<0.05). The RPP was significantly lower at 67°R, 47°R, and 15°R than in the upright position immediately after exercise (176±23, 177±22, and 173±26, respectively, vs. 241±42 mmHg×beats/min×10⁻²; P<0.001). CONCLUSIONS: At an angle of less than 67°R, exercise increases CBFV and reduces RPP, relative to those during exercise in the upright position. This hemodynamic effect was most prominent at 15°R, where cerebral circulation was further increased in the recovery phase.
