Unilateral absence of a pulmonary artery is an uncommon anomaly, which presents as an isolated lesion or in combination with other congenital heart disease such as TOF or PD^. We encountered three cases of isolated unilateral absence of a pulmonary artery;one was left pulmonary artery agenesis with right sided aortic arch and the others were right pulmonary artery agenesis with left sided aortic arch. Plain chest radiograph showed considerable loss of unilateal lung volume and lack of ipsilateral hilar shadow. Pulmonary angiogram which was done in two cases, revealed proximal interruption of a pulmonary artery. Chest CT was done in only one case, on which right pulmonary artery was absent and was replaced by adipose tissue. CT with its clean demonstration pulmonary artery without any evidence of aquired obstruction of a pulmonary artery by pulmonary embolism or tumor invasion, maybe a valuable method for evaluaton of the unilateral absence of a pulmonary artery.

BACKGROUND: Lung cancer is one of the leading causes of cancer-related deaths throughout the world. The gene tumor protein 53 (TP53) is frequently mutated in cases of lung cancer. This study was performed to investigate the frequencies and types of mutations in the TP53 gene in Korean patients with lung cancer. METHODS: We obtained tissue samples from 80 lung cancer patients and synthesized TP53 cDNA by using RNA isolated from these tissues by performing reverse transcriptase polymerase chain reaction. Hybridization and denaturing high-performance liquid chromatography were performed to identify the TP53 gene mutations, and then, the mutations were validated by direct sequencing. RESULTS: Forty mutations out of the 80 patients (50.0%) were noted in the TP53 gene. The frequencies of TP53 gene mutation for different cancer types, namely, squamous cell carcinoma, adenocarcinoma, and small cell carcinoma were 61.1%, 27.3%, and 26.7%, respectively. The mutation frequencies in the different regions of the gene were 10.0% for exon 4, 35.0% for exon 5, 12.5% for exon 6, 22.5% for exon 7, 17.5% for exon 8, and 2.5% for exon 9. The frequently mutated positions were codon 179 in exon 5, codons 202 and 220 in exon 6, and codons 266 and 273 in exon 8. CONCLUSIONS: Exon 5 was the most frequently mutated region in the TP53 gene. Compared to the patients with the other types of cancers, patients with squamous cell carcinoma showed a higher frequency of TP53 mutation. Codon 179 was the most frequently mutated codon in the TP53 gene.

Background:
Transforaminal epidural steroid injection (TFESI) is a conservative treatment for patients with lumbar disc herniation (LDH). However, there are reports of various complications that can occur after TFESI; among these, paraplegia is a serious complication. Case: A 70-year-old woman who was unable to lie supine due to low back pain exacerbation during back extension underwent TFESI. After injection, there was pain relief and the patient was able to lie supine; however, paraplegia developed immediately. Magnetic resonance imaging confirmed cauda equina syndrome (CES) due to nerve compression from L1–2 LDH. We determined that the patient's LDH was already severe enough to be considered CES and that the TFESI procedure performed without an accurate understanding of the patient's condition aggravated the disease.
Conclusions
It is important to accurately determine the cause of pain and disease state of a patient to establish a correct treatment plan before TFESI is performed.

The incidence of heterotopic ossification (HO) was reported to be higher in combat-injured patients than in civilian trauma patients. HO is often considered a possible cause of residual limbs pain in amputee. Here, we report the case of a 21-year-old male, who underwent a traumatic right transfemoral and left transtibial amputation with two segments of painful HO around his left amputation site. We report the effect of extracorporeal shock wave therapy (ESWT) on size and pain associated with HO. After ESWT, the visual analog scale score decreased from 5∼6 to 0∼1 and the size of two masses decreased from 13.1 × 6.7 mm and 12.5 mm to 11.9 × 4.7 mm and 12.2 mm, respectively. To the best of our knowledge, this is the first case that has reported on the treatment of HO using ESWT for a traumatic transtibial amputation patient. The case suggests that ESWT could serve as a complementary treatment for HO in traumatic amputation patient.

Despite the recent advances in immunosuppression, antibody mediated acute rejection is associated with a poor prognosis. Therapeutic interventions such as polyclonal antibodies, rituximab, and plasmapheresis have been used for the treatment of antibody mediated rejection. However, these treatments are associated with a serious infectious complication. Recently, Intravenous immunoglobulin (IVIG) are known to have powerful immunomodulatory effects on inflammatory and infectious disease. We successfully rescued two patients who had concomitant antibody mediated rejection and BK virus infection. IVIG could be a preferable choice for treatment of humoral rejection in the presence of infection.

For the treatment of coarction of aorta, surgical intervention has been known as a standard therapy.During last decade balloon angioplasty for coarctation of the aorta has been reported as a successful and safe procedure in about 300 cases. This angioplasty was done mainly in infants and children, and little cases in adults and adolescents. A 22 year-old adult with coarctation of aorta have recieved balloon angioplasty. He visited to emergency room due to severe headache and the blood presure of arm was 240/130mmHg at emergency room. The blood pressure at ward was 168/92mmHg in upper extremities, 104/82mmHg in lower extrimities. His aortogram showed coarctation of thoracic aorta below left subclavian artery. The pressure gradient beween ascending aorta and right femoral artery was decreased from 60mmHg to 0mmHg after balloon dilatation (2 times, balloon diameter 18mm). There were no significant complications. The follow-up magnetic resonance image in 4 month after balloon angioplasty showed no evidence of restenosis or saccular aneurysm. Initial hypertension turned to normal blood pressure in 4 months after balloon angioplasty. This adult case of successful balloon angioplasty for coarctation of aorta is the first case reported in Korea.

The Nuss procedure has good cosmetic effects, but it could be cause of bleeding and organ injury during dissection of the anterior mediastinum. We have made an effort to overcome the defects of the traditional method through the anterior mediastinum, thus we developed a transilluminated introducer that made it safer and simpler to operate within a 1 cm incision only. A total of 67 patients underwent the Nuss procedure using the transilluminated introducer. Thirty-six patients underwent the procedure with the transilluminated introducer only (age<14 years). Thirty-one patients had an additional thoracoscopy (age> or =14 years). There were no major complications, such as massive bleeding or organ injury in the thoracic cavity during or after the Nuss procedure. Our findings demonstrated that the anterior mediastium could be dissected simply and safely by the use of a transilluminated introducer during the Nuss procedure without fatal major complications, such as bleeding and organ injury.

BACKGROUND/AIMS: New definitions of acute kidney injury (AKI) have recently emerged. Some studies have suggested that duration of AKI is an additional predictive parameter for mortality. Here, we evaluated whether AKI duration was predictive of long-term mortality in patients with hospital-acquired acute kidney injury (HAAKI). METHODS: We prospectively enrolled patients who developed HAAKI at an urban university hospital, from September 2007 to August 2008 and followed them until December 2011. Patients were divided into two groups by duration of the AKI (1 to 5 days vs. > or = 6 days), and long-term mortality was compared. RESULTS: HAAKI developed in 1.2% of patients during the enrollment period. The median follow-up period was 240 days (interquartile range, 53 to 1,428). In 42.3% of patients (n = 52), the AKI lasted 1 to 5 days, while it lasted > or = 6 days in 57.7% (n = 71). Survival analysis showed that a longer duration of AKI increased the risk of death. Long-term survival was significantly different in the two groups. CONCLUSIONS: The duration of AKI influenced mortality rates in hospitalized patients. Thus, AKI duration is a parameter affecting mortality in HAAKI.
