PURPOSE: To evaluate the clinical efficacy of balloon catheter dilatation in the treatment of esophageal achalasia. MATERIALS AND METHODS: Seven patients(three males and four females) with esopha-geal achalasia were treated with balloon catheter dilatation. Balloon catheters of variable sizes were used depending on patient's conditions. The patients were followed up over a period of 12-39months. RESULTS: Balloon catheter dilatation in esophageal achalasia was successful in all patients without esophageal perforation. All patients were relieved from dysphagia. Recurrence was not found in 5 patients on long term follow-up study, but was seen in 2 patients after 18 and 21 months, respectively. CONCLUSION: Balloon catheter dilatation was a safe and effective method in the treatment of esophageal achalasia with low recurrence rate of 29% on follow-up study.

PURPOSE: Cytolethal distending toxin (CDT) considered as a key factor of localized aggressive periodontitis, endocarditis, meningitis, and osteomyelitis is composed of five open reading frames (ORFs). Among of them, the individual role of CdtA and CdtC is not clear; several reports presents that CDT is an AB2 toxin and they enters the host cell via clathrin-coated pits or through the interaction with GM3 ganglioside. So, CdtA, CdtC, or both seem to be required for the delivery of the CdtB protein into the host cell. Moreover, recombinant CDT was suggested as good vaccine material and antibody against CDT can be used for neutralization or for a detection kit. MATERIALS AND METHODS: We constructed the pET28a-cdtC plasmid from Aggregatibacter actinomycetemcomitans Y4 by genomic DNA PCR and expressed in BL21 (DE3) Escherichia coli system. We obtained the antibody against the recombinant CdtC in mice system. Using the anti-CdtC antibody, we test the native CdtC detection by ELISA and Western Blotting and confirm the expression time of native CdtC protein during the growth phase of A. actinomycetemcomitans. RESULTS: In this study we reconstructed CdtC subunit of A. actinomycetemcomitans Y4 and generated the anti CdtC antibody against recombinant CdtC subunit expressed in E. coli system. Our anti CdtC antibody can be interacting with recombinant CdtC and native CDT in ELISA and Western system. Also, CDT holotoxin existed at 24h but not at 48h meaning that CDT holotoxin was assembled at specific time during the bacterial growth. CONCLUSION: In conclusion, we thought that our anti CdtC antibody could be used mucosal adjuvant or detection kit development, because it could interact with native CDT holotoxin.

PURPOSE: In this single center study, we assessed the timing of presentation of necrotizing enterocolitis (NEC) diagnosed by sonography according to the gestational age. METHODS: We retrospectively reviewed the medical records of 49 newborn patients who were diagnosed with NEC (modified Bell's stage II and higher according to abdominal sonography and simple abdominal radiography) and were admitted to the neonatal intensive care unit of St. Mary's Hospital between January 2008 and December 2012. Infants were grouped according to their gestational age (GA): Group I (GA <28 weeks), Group II (GA, 28-32 weeks), Group III (GA, 33-36 weeks), and Group IV (GA > or =37 weeks); early-onset NEC was considered when NEC developed at <14 days of age and late-onset NEC was considered when NEC developed at > or =14 days of age. RESULTS: The number of infants in each group were: Group I (n = 16), Group II (n = 20), Group III (n = 11), and Group IV (n = 2). The mean age at diagnosis of NEC was: Group I (31.6 days), Group II (15.9 days), Group III (11.0 days), and Group IV (2.0 days). Early-onset NEC developed at a mean of 5.5 days of age, whereas late-onset NEC developed at a mean of 36.1 days of age. CONCLUSION: Based on early sonographic diagnosis, infants with lower gestational ages developed NEC at a more advanced postnatal age as compared to more mature infants. However, further studies are needed to understand the etiology of this disease process.

6.Retreatment of implant overdenture using Milled Bar and Attachment in a patient using a unilateral prosthetic arm:A case report

The use of implants could improve the support, retention, and stability of removable prosthetic restoration for fully edentulous patients with severe alveolar bone resorption. When the prosthesis is manufactured without accurate diagnosis and evaluation, this may lead to unfavorable treatment result. The patient in this case had the treatment of implant overdentures at a private dental clinic, but visited the hospital for retreatment due to soft tissue pain and decreasing retention of existing dentures. The vertical dimension was raised compared to the existing dentures, and overdentures were manufactured using milled bars and additional attachments. The clinical results were satisfactory in the aspect of improved oral hygiene maintenance, function and esthetics.

BACKGROUND: Pulmonary complications including pneumonia and pulmonary edema frequently develop in critically ill surgical patients. Lung ultrasound (LUS) is increasingly used as a powerful diagnostic tool for pulmonary complications. The purpose of this study was to report how LUS is used in a surgical intensive care unit (ICU). METHODS: This study retrospectively reviewed the medical records of 67 patients who underwent LUS in surgical ICU between May 2016 and December 2016. RESULTS: The indication for LUS included hypoxemia (n = 44, 65.7%), abnormal chest radiographs without hypoxemia (n = 17, 25.4%), fever without both hypoxemia and abnormal chest radiographs (n = 4, 6.0%), and difficult weaning (n = 2, 3.0%). Among 67 patients, 55 patients were diagnosed with pulmonary edema (n = 27, 41.8%), pneumonia (n = 20, 29.9%), diffuse interstitial pattern with anterior consolidation (n = 6, 10.9%), pneumothorax with effusion (n = 1, 1.5%), and diaphragm dysfunction (n = 1, 1.5%), respectively, via LUS. LUS results did not indicate lung complications for 12 patients. Based on the location of space opacification on the chest radiographs, among 45 patients with bilateral abnormality and normal findings, three (6.7%) and two (4.4%) patients were finally diagnosed with pneumonia and atelectasis, respectively. Furthermore, among 34 patients with unilateral abnormality and normal findings, two patients (5.9%) were finally diagnosed with pulmonary edema. There were 27 patients who were initially diagnosed with pulmonary edema via LUS. This diagnosis was later confirmed by other tests. There were 20 patients who were initially diagnosed with pneumonia via LUS. Among them, 16 and 4 patients were finally diagnosed with pneumonia and atelectasis, respectively. CONCLUSIONS: LUS is useful to detect pulmonary complications including pulmonary edema and pneumonia in surgically ill patients.

Adrenal cortical neoplasm, especially carcinoma, is extremely rare in pediatric patients. We describe here a rare pediatric case of adrenal cortical neoplasm. A 2-year-old girl presented with an enlarged clitoris. The other physical findings and laboratory tests were nonspecific. The magnetic resonance imaging showed a 4 cm-sized heterogeneously enhancing soft tissue mass with calcification in the left adrenal gland. The mass was removed by laparoscopic operation. Grossly, several fragments of reddish tan soft tissue were present, and they weighed 19 gm in total. Microscopically, there were capsular invasion, diffuse/solid growth pattern with focal necrosis, high cellularity, cytoplasmic eosinophilia, marked nuclear pleomorphism, high N/C ratio, prominent nucleoli, atypical mitotic figures and calcifications, which all suggested adrenal cortical neoplasm of histologic malignancy. On immunohistochemistrical staining, there were positive reactivities to pancytokeratin, cytokeratin 7/20, CEA, inhibin and p53. The Ki-67 labeling index was about 6%. All these findings were indicative of adrenal cortical neoplasm of histologic malignancy.

Pituitary adenomas are frequent intracranial tumors with generally benign prognosis but acute hemorrhage into tumor with necrosis is a severe complication and can potentially result in fatal outcome, if not diagnosed or treated early. While many precipitating factors have been known, even a mild blunt force shown in this case could play a role in the catastrophic complication of the pituitary adenoma. We report a rare forensic case of post-traumatic apoplexy sustained in a preexisting pituitary adenoma with a mild blunt force to the face.
