Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.

BACKGROUND: Cardiogenic pulmonary edema increases nonspecific airway responsiveness in humans and animals. Increased extravascular lung water from overt pulmonary edema to subclinical interstitial edema is a common finding in patients with chronic renal failure. Several studies carried out to assess pulmonary function disturbances in this condition have documented a reduction in forced expiratory volume that usually reverses after hemodialysis, suggesting airway edema as the underlying mechanism. This interstitial edema may also lead to nonspecific bronchial hyperre- sponsiveness. We hypothesized that patients with chronic renal failure may present nonspecific bronchial hyperresponsiveness due to subclinical interstitial pulmonary edema. METHODS: We studied 18 chronic renal failure undergoing regular hemodialysis 3 times a week (New York Heart Association Class II) without concomittent disease. These patients were checked pulmonary function test and metacholine provocation test before hemodialysis and same procedure was repeated if responsive, after hemodialysis. RESULTS: 1) 12 out of 18 patients before hemodialysis were reactive in metacholine provocation test (66.7%) before hemodialysis. This airway hyperresponsiveness were decreased after hemodialysis. 2) Pulmonary function was improved after hemodialysis and change in FEV1 was correlated with change in weight(r= -0.62, p<0.01). 3) There was a close correlation between log PD20 and FEF25, which is one of the variables of the peripheral airways(r=0.58, p<0.05). CONCLUSION: We speculated interstitial pulmonary edema may play a significant role in bronchial hyperresponsiveness and lung function impaired in patients with chronic renal failure.

Cutaneous horn is a clinica) diagnosis based upon the presence of a large protuberant mass of keratin. We report a case of cutaneous horn arising from keratoacanthoma in a 76-year old woman. The patient showed a dome-shaped nodule 2n in diameter with a central crater on thc right temple area. A yellow brown colored cornical hyperkeratotic protruding lesion(0.7* 0.7cm size) from the central crater of the nodule was also observed. Histopathological findings of the lesions showed charaeteristic findings of keratoacanfhoma and cutaneous horn. The lesion was removed by surgical excision.

To evaluate the risk and factors associated with seizure recurrence in children with epilepsy while receiving the adequate anticonvulsant treament, we studied 58 patients with newly diagnosed epilepsy who were followed prospectively for a median of 26 months (range 7 to 54). The results were as follows: 1) Forty-four of the 58 patients (75.9%) had recurrence of seizure. 2) The rate of recurrence according to type of seizure was observed to be 22 patients (68.8%) in generalized tonic-clonic seizure, 6 patients (85.7%) in simple partial seizure, 5 patients (83.3%) in complex partial seizure, 3 patients (100%) in mixed seizure, 2 patients (100%) in absence, 3 patients (100%) in infantile spasm, 1 patient (100%) in atonic seizure, 2 patients (50%) in secondary generalized seizure. There was no significant difference in the risk of recurrence observed among these seizure types. 3) The risk of recurrence varied according to the history of seizure, seizure recurrence was observed in 100% of the cases with history of neonatal seizure, 72.7% of the cases with febrile convulsion, and 73.3% of the cases with non-specific history. No significant difference was observed among these past history of seizure. 4) The rate of seizure recurrence according to electroencephalographic abnormalities did not differ significantly. Seizure recurrence was noted in 13 of the 18 patients with mildly disordered tracings (72.2%), 15 of the 20 patients with moderate abnormality (75.0%), and 12 of the 16 patients with severe abnormality (75.0%). 5) Recurrence rate according to cause of seizure was more significantly frequent in those with symptomatic epilepsy than in those with idiopathic type (100% vs 70.2%, p<0.05). 6) The frequency percentage of seizure recurrence by age groups of below 1 year, 1 to 3 years, 4 to 6 years, and above 6 years at onset of seizure were 100, 66.7, 57.1, and 72.7, respectively. The rate of seizure recurrence was significantly highest in patients aged below 1 year at onset of seizure. 7) There was significant difference in seizure recurrence between those with and without abnormalities as shown by neurologic examination (100% vs 70.8%, p<0.05). 8) There was no consistent difference in valproic acid serum levels between those who had a recurrence and those who did not. The patients receiving phenobarbital had significantly high serum levels of the phenobarbital in recurrent groups than those who had no recurrence. In conclusion, factors associated with an increased risk of seizure recurrence were early age at onset of epilepsy, symptomatic epilepsy, and neurologic abnormalities. We found no associations between risks of recurrence and types of epilepsy, or electroencephalographic abnormalities.

The aim of this study was to evaluate the role of demineralized and particulate autogenous tooth, and interleukin-6 in bone regeneration. A demineralized and particulate autogenous tooth was prepared and human osteoblast-like cells (MG63) and human osteosarcoma cells were inoculated into the culture. The rate of cell adhesion, proliferation and mineralization were examined, and the appearance of cellular attachment was observed. An 8 mm critical size defect was created in the cranium of rabbits. Nine rabbits were divided into three groups including: An experimental group A (3 rabbits), in which a demineralised and particulate autogenous tooth was grafted; an experimental group B (3 rabbits), in which a demineralized, particulate autogenous tooth was grafted in addition to interleukin-6 (20 ng/mL); and a control group. The rabbits were sacrificed at 1, 2, 4 and 6 weeks for histopathological examination with H-E and Masson's Trichrome, and immunohistochemistry with osteocalcin. The cell-based assay showed a higher rate of cell adhesion, mineralization and cellular attachment in the experimental group A compared with the control group. The animal study revealed an increased number of osteoclasts, newly formed and mature bones in the experimental group A compared with the control group. Eventually, a higher number of osteoclasts were observed in the experimental group B. However, the emergence of newly formed and mature bone was lower than in the experimental group A. The current results suggest that treatment with demineralized and particulate autogenous tooth and interleukin-6 is not effective in stimulating bone regeneration during the bone grafting procedure.

Because of the possibility of increased the risk of soft tissue or bone infection, surgeon have been somewhat reluctant to use the anterior cervical approach in spinal injury patients who had previously undergone tracheostomy. The authors investigated whether the use of a Caspar plate in such patients during anterior cervical fixation altered the risk of infection. We analyzed the mechanism and level of injury, operative procedures, post-operative course and infection in 12 cervical injury patients with previous tracheostomy. The procedure had been performed on the day of injury because of semicoma resulting from combined head injury in two cases, and because of multiple rib fracture with hemothorax, and old age with chronic obstructive lung disease in one case each; it had been performed between 1-6 days after injury because of high fever with pneumonia and atelectasis in eight cases. The interval between tracheostomy and anterior fixation was 5-20(average, 13) days. During clinical follow-up at 8-21 (average, 16) months, bone union without infection was observed in all patients. The authors concluded that in patients with cervical cord injury, tracheostomy did not increase the risk of infection in subsequent anterior cervical fixation using a Caspar plate.

STUDY DESIGN: Level III, retrospective studies. OBJECTIVES: This study is conducted to evaluate the effect and usefulness of ultrasound guided facet block for the outpatients who complained of chronic lower back pain. SUMMARY OF THE LITERATURE REVIEW: Facet joint syndrome was introduced in 1976, by Mooney V. It was considered to be one of the major causes of low back pain. MATERIALS AND METHODS: Between October 2009 to March 2011, 98 cases were selected from the outpatients who complained of chronic lower back pain for more than 3 months. The patients had no surgery history and did not complain of neuromuscular symptoms, and they had more than three times outpatient care at least and could be followed up for 1 year. The patients were divided into three groups; first was the ultrasound guided facet block group (27 cases), second was the Fluoroscopy guided facet block group (39cases) and third was the conservative group (32 cases).The clinical results were analyzed using Kim's criteria and the Visual Analog Scale score, ODI score, Physician's global assessment (subjective), Patient's global assessment (Objective). RESULTS: The VAS score was improved from an average of 7.75+/-1.5 to 4.47+/-2.4 in the ultrasound guided facet block group, and from 7.81+/-1.4 to 4.39+/-2.6 in the Fluoroscopy guided facet block group, and from 7.87+/-1.3 to 6.24+/-2.1 in the conservative group. The VAS score, Kim's criteria, ODI score, Physician's global assessment (subjective), and Patient's global assessment (Objective) showed statistically significant improvement in the ultrasound guided facet block group and Fluoroscopy guided facet block group. CONCLUSION: In the outpatient clinics, comparing with the group that underwent conservative treatment with medication, the group treated with ultrasound for block could have better results in clinical improvement.

The segmental spread of epidural analgesia was measured in seventeen surgical patients aged between 17 and 52 years, and in fourteen patients between 60 and 77 years. The upper level in the young was 6.29(+/-1.56) thoracic vertebra level, but in the elderly was 4 (+/-0.65_ thoracic vertebra level at 20 minutes after epidural injection of 1.5% lidocaine 20 ml. A given volume of solution spreads to 0.9, 1.07, 1.54, 2.29 segments greater upper extent at 5, 10, 15, 20 minutes after epidural injection and 0.57, 1.07 segments greater lower extent at 5, 10 minutes in the elder than young. So with increasing age relatively small amounts of solution are required, to produce the same extent of anesthesia in the young.
