Author performed this experiment to define the most important factor preventing the intimal thickening. An endothelium of abdominal aorta in the rat was denuded by two different wires having same caliver. The degree of injury was limited to the endothelial cells in one, and extended to the internal elastic lamina in another. The results showed that at 72 hours, in the case of superficial injury, the entire injury site was covered by new regenerating cells, but in the case of disruption of the internal elastic lamina, the migrating smooth muscle cell completely reached into the intima and resulted in intemal thickening. Similar findings persisted to 1 week later. Above results suggest the most important factor preventing the intimal thickening in endothelial injury is the depth of the injury which limited within the endothelial cells without extending into the internal elastic lamina and medial smooth muscle cells.

Purpose: We present a case of a subconjunctival abscess formation with periorbital cellulitis following scleral buckling (SB) and pars planar vitrectomy (PPV).Case summary: A 51-year-old female patient came to our hospital with complaints of ocular pain and discharge in the right eye. The patient underwent SB and several times of PPV for multiple rhegmatogenous retinal detachment due to acute retinal necrosis. The onset of symptoms was 9 months after the last vitrectomy. A subconjunctival abscess was seen at 8 o'clock position on slit lamp, and periorbital cellulitis was observed on computed tomography image, the patient underwent an incision and drainage (I&D) surgery. Another 9 months later, a subconjunctival abscess was newly found at 4 o'clock position. Since the abscess site and the position of the stitch which sutured the buckle sponge was exactly same, the cause of infection was thought to be the sponge suture materials. Along with I&D surgery, the suture at the end of the sponge was removed. After then, conjunctival and periorbital inflammation got improved and the patient is still in the process of examination to date. Conclusions Subconjunctival abscess or periorbital cellulitis is a rare complication of SB, caused by the use of an exogenous materials such as silicon sponge or suture stitches. Therefore, when ocular pain or inflammation is observed in SB patients, early detection and active treatment is required for suspected periorbital cellulitis.

OBJECTIVES: Schizophrenia manifests a variety of interindividual differences in therapeutic response to antipsychotics. This might be attributable to dopamine and serotonin receptors that a important target for various antipsychotics, and the D3 receptor(DRD3) alleles they carry. The purpose of our study was to investigate whether the plasma levels of homovanillic acid(HVA) and 5-hydroxyindoleacetic acid(HIAA), and the polymorphism of DRD3 can be held as a predictor of treatment response ni chronic schizophrenic patients. METHODS: Therapeutic response for 16 korean schizophrenia patient treated during 48 weeks were assessed by PANSS used as the clinical symptom rating scales. The levels of concentration of HVA and 5-HIAA were examined by HPLC at baseline and at 48 weeks. We classified the polymorphism of DRD3 receptor using amplifying by polymerase chain reaction(PCR). RESULTS: Neither concentrations of HVA and 5-HIAA nor genotype of dopamine 3 receptor were not significantly associated with the therapeutic response. But, the patients who has A1 alleles of DRD3 gene showed poor therapeutic responses. CONCLUSION: A1 allele of DRD3 gene is associated with poor prognosis of chronic schizophrenia.

PURPOSE: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. MATERIALS AND METHODS: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. RESULTS: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). CONCLUSION: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

PURPOSE: Prolonged duration of cardiopulmonary bypass aggravates the degree of inflammation and coagulopathy. We investigated the influence of 6% hydroxyethyl starch (HES) 130/0.4 on coagulation and inflammation compared with albumin when used for both cardiopulmonary bypass priming and perioperative fluid therapy in patients undergoing complex valvular heart surgery. MATERIALS AND METHODS: Fifty four patients were randomly allocated into albumin-HES, albumin-nonHES, and HES-HES groups. The cardiopulmonary bypass circuit was primed with 5% albumin in the albumin-HES and albumin-nonHES group, and with HES in the HES-HES group. As perioperative fluid, only plasmalyte was used in the albumin-nonHES group whereas HES was used up to 20 mL/kg in the albumin-HES and albumin-HES group. Serial assessments of coagulation profiles using the rotational thromboelastometry and inflammatory markers (tissue necrosis factor-alpha, interleukin-6, and interleukin-8) were performed. RESULTS: Patients' characteristics and the duration of cardiopulmonary bypass (albumin-HES; 137+/-34 min, HES-HES; 136+/-47 min, albumin-nonHES; 132+/-39 min) were all similar among the groups. Postoperative coagulation profiles demonstrated sporadic increases in clot formation time and coagulation time, without any differences in the actual amount of perioperative bleeding and transfusion requirements among the groups. Also, inflammatory markers showed significant activation after cardiopulmonary bypass without any differences among the groups. CONCLUSION: Even in the presence of prolonged duration of cardiopulmonary bypass, HES seemed to yield similar influence on the ensuing coagulopathy and inflammatory response when used for priming and perioperative fluid therapy following complex valvular heart surgery compared with conventional fluid regimen including albumin and plasmalyte.

An 8-years old boy with facial asymmetry and unilateral posterior crossbite on the left side received orthopedic and orthodontic treatment. During the first phase of treatment, the narrow maxillary arch was expanded using an acrylic plate. Then, the acrylic plate was used as a bite block with occlusal indentations from the construction bite that was obtained with the incisors in a coincident dental midline. After the position of the mandible was stabilized, the second phase of orthodontic treatment was initiated using fixed appliances for detailing of the occlusion. Skeletal symmetry, ideal occlusion, and coincident dental midlines were thus achieved. Functionally, occlusal force balance and masticatory muscle activity were improved, and the chewing patterns were normalized.
