Background/Aims: Prokinetics such as mosapride citrate CR (conventional-release; Gasmotin) are commonly used in functional dyspepsia (FD). This study aims to evaluate the efficacy and safety of once-a-day mosapride citrate SR (DWJ1252), a sustained-release formulation of mosapride citrate, compared with mosapride citrate CR 3 times a day, in patients with FD. Methods: In this multicenter, randomized, double-blind, active-controlled, non-inferiority study, 119 patients with FD (by the Rome III criteria, 60 for mosapride citrate SR and 59 for mosapride citrate CR) were randomly allocated to mosapride citrate SR once daily or mosapride citrate CR thrice daily for 4 weeks in 16 medical institutions. Primary end point was the change in gastrointestinal symptom (GIS) score from baseline, assessed by GIS questionnaires on 5-point Likert scale after 4-week treatment. Secondary end points and safety profiles were also analyzed. Results: The study included 51 and 49 subjects in the mosapride citrate SR and mosapride citrate CR groups, respectively. GIS scores at week 4 were significantly reduced in both groups (mean ± SD: − 10.04 ± 4.45 and − 10.86 ± 5.53 in the mosapride citrate SR and mosapride citrate CR groups, respectively; P < 0.001), and the GIS changes from baseline did not differ between the 2 groups (difference, 0.82 point; 95% CI, − 1.17, 2.81; P = 0.643). Changes in GIS at weeks 2 and 4 and quality of life at week 4, and the improvement rates of global assessments at weeks 2 and 4, did not differ between the groups. Adverse events were similar in the 2 groups, and there were no serious adverse events. Conclusion In patients with FD, mosapride citrate SR once daily is as effective as mosapride citrate CR thrice daily, with a similar safety profile.

Background and Objectives: The relationship between the hospital percutaneous coronary intervention (PCI) volumes and the in-hospital clinical outcomes of patients with acute myocardial infarction (AMI) remains the subject of debate. This study aimed to determine whether the in-hospital clinical outcomes of patients with AMI in Korea are significantly associated with hospital PCI volumes. Methods: We selected and analyzed 17,121 cases of AMI, that is, 8,839 cases of non-ST-segment elevation myocardial infarction and 8,282 cases of ST-segment elevation myocardial infarction, enrolled in the 2014 Korean percutaneous coronary intervention (K-PCI) registry. Patients were divided into 2 groups according to hospital annual PCI volume, that is, to a high-volume group (≥400/year) or a low-volume group (<400/year). Major adverse cardiovascular and cerebrovascular events (MACCEs) were defined as composites of death, cardiac death, non-fatal myocardial infarction (MI), stent thrombosis, stroke, and need for urgent PCI during index admission after PCI. Results: Rates of MACCE and non-fatal MI were higher in the low-volume group than in the high-volume group (MACCE: 10.9% vs. 8.6%, p=0.001; non-fatal MI: 4.8% vs. 2.6%, p=0.001, respectively). Multivariate regression analysis showed PCI volume did not independently predict MACCE. Conclusions Hospital PCI volume was not found to be an independent predictor of in-hospital clinical outcomes in patients with AMI included in the 2014 K-PCI registry.

PURPOSE: Split thickness skin graft is a frequently used reconstructive technique in burn wound, but the ideal dressing material of the donor site is yet to be developed. The donor sites have been managed with various dressing materials. The aim of this study is to compare four different dressing materials for management of the donor site in a prospective trial. METHODS: This study is based on 85 patients who had undergone split thickness skin graft from September 2011 to February 2012. The grafts harvested with a same manner and the donor sites were managed with one of the four dressing materials: Aquacel Ag(R), Mepitel(R), Bactigra(R), Op-Site(R). We compared post-operative pain scale, the time required epithelialization, ease of application, post-operative infection and number of dressings. RESULTS: Aquacel Ag(R) was the more painless dressing materials in post-operative day 1, 4, 7, 10 than Mepitel(R), Bactigra(R), Op-Site(R). Number of dressings was more lower for Aquacel Ag(R) with Mepitel(R). Ease of application was more higher for Aquacel Ag(R) with Mepitel(R). But Aquacel Ag(R) was not earliest epithelialization. The incidence of infection was not low in Aquacel Ag(R). CONCLUSION: Aquacel Ag(R) dressing is better than other dressing materials for split thickness skin graft donor site in the number of dressings, ease of application, post-operative pain.

Suaeda asparagoides (Miq.) has long been used as a Korean folk herbal medicine for the treatment of functional gastrointestinal disorders. However, reports on its pharmacological activity on gastrointestinal motility are scarce. The present study investigated the effects of Suaeda asparagoides water fraction of the extract (SAWF) on antral motility in vitro. Muscle strips from rat gastric antrum were set up in an organ bath in a circular orientation. SAWF (100 microg/mL) inhibited the spontaneous contraction of antral circular muscle strips. These inhibitory effects were not significantly affected by tetrodotoxin (1 microM), N omega-Nitro-L-arginine methyl ester hydrochloride (100 microM), 1H-(1,2,4)oxadiazolo(4,3-a)quinoxalin-1-one (10 microM), ryanodine (10 microM) and phentolamine (10 microM). SAWF-induced inhibition was mostly restored by cyclopiazonic acid (10 microM). Furthermore, the beta-adrenergic receptor antagonist, propranolol (10 microM), abolished SAWF-induced inhibition. These results suggest that SAWF may exert its activity on gastrointestinal smooth muscle via a-adrenergic receptors and sarcoplasmic reticulum Ca2+ ATPase.

The incidence of imported malaria has been increasing in Korea. We reviewed data retrospectively to evaluate the epidemiology, clinical features, and outcomes of imported malaria from 1995 to 2007 in a university hospital. All patients diagnosed with imported malaria were included. Imported malaria was defined as a positive smear for malaria that was acquired in a foreign country. A total of 49 patients (mean age, 35.7 year; M : F = 38 : 11) were enrolled. The predominant malarial species was Plasmodium falciparum (73.5%), and the most frequent area of acquisition was Africa (55.1%), followed by Southeast Asia (22.4%) and South Asia (18.4%). Fourteen-patients (30.6%) suffered from severe malaria caused by P. falciparum and 1 patient (2.0%) died of multiorgan failure. Most of the patients were treated with mefloquine (79.2%) or quinine (10.2%); other antimalarial agents had to be given in 13.2% treated with mefloquine and 44.4% with quinine due to adverse drug events (ADEs). P. falciparum was the most common cause of imported malaria, with the majority of cases acquired from Africa, and a significant number of patients had severe malaria. Alternative antimalarial agents with lower rates of ADEs might be considered for effective treatment instead of mefloquine and quinine.

BACKGROUND: Soft tissue defects of the posterior heel of the foot present difficult reconstructive problems. This paper reports the authors' early experience of five patients treated with a lateral calcaneal artery adipofascial flap. METHODS: Between 2003 and 2007, five patients (3 males and 2 females) with soft-tissue defects over the posterior heel underwent a reconstruction using a lateral calcaneal artery adipofascial flap and a full-thickness skin graft. The flap sizes ranged from 3.5 x 2.5 cm to 5.5 x 4.0 cm. RESULTS: All five flaps survived completely with no subsequent breakdown of the grafted skin, even after regularly wearing normal shoes. The adipofascial flap donor sites were closed primarily in all patients. CONCLUSIONS: Lateral calcaneal artery adipofascial flaps should be included in the surgical armamentarium to cover difficult wounds of the posterior heel of the foot. These flaps do not require the sacrifice of a major artery to the leg or foot, they are relatively thin with minimal morbidity at the donor site, and leave a simple linear scar over the lateral aspect of the foot.

PURPOSE: Despite the free tissue transfer using microsurgical technique being the current trend of soft tissue reconstruction of the hand, the pedicled groin flap has the advantage to provide coverage for the mangled hand without necessitating the use of a damaged arterial system and also providing the benefit of saving the arterial system for later free tissue transfer. This report presents the author's experience using pedicled groin flap in four cases of mangled hands with massive bone and soft tissue defects requiring later thumb reconstruction with the free wrap around flap. MATERIALS AND METHODS: The patients' age ranged from 30 to 51 years; three patients were male and one was female. The causes of mangled hand included two machinery crush injuries, one laboratory explosion and one motor vehicle accident. While evaluating the post-operative results, factors like flap survival, complications, stability in opposition, pinch power and 2 point discrimination were taken into account. RESULTS: All massive soft tissue defects of the hands were completely covered with pedicled groin flap successfully. The reconstructed thumb using free wrap around flap did not have any limitation in opposition. There was no occurrence of post-operative infection and all the flaps survived completely. The average pinch power was 70% of the contralateral intact thumb and average 2 point discrimination was 10 mm. CONCLUSION: The pedicled groin flap for the reconstruction of the massive soft tissue defects of the hand with subsequent reconstruction of the thumb with a wrap around flap is a very useful procedure. The combined use of pedicled groin flap and wrap around flap allows adequate coverage of sizable soft tissue defects and functional thumb opposition in cases of reconstruction of the mangled hands.

The bacterial flagellar structure can be divided into the basal body, the hook and the filament. Three minor components called hook associated proteins (HAP1, HAP2 and HAP3) form a junction between the hook and the filament (HAP1 and HAP3) and a capping structure at the distal end of flagellar filament (HAP2). Vibrio vulnificus is a halophilic pathogenic bacterium that is locomotive by means of a polar flagellum. From a V. vulnificus genome sequencing project, we obtained sequences of V. vulnificus flgK (Vv-flgK), flgL (Vv-flgL), and flaH (Vv-flaH) genes that encode HAP1, HAP3, and HAP2, respectively. To investigate roles of the HAP proteins, deletion mutants of the Vv-flgK, Vv-flgL and Vv-flaH were constructed. Electron microscopic analysis showed that the Vv-flgK or Vv-flgL mutant did not produce an intact polar flagellum while the Vv-flaH mutant produced a fragile flagellar structure. Western blot analysis against a major polar flagellin proposed that the null HAP1 and HAP3 mutations resulted in a failure of normal flagellar assembly since flagellins produced by the mutants were secreted out in the culture supernatants without long flagellar filaments. Motility was completely abolished by a single mutation in HAP1 or HAP3, and the HAP2 mutant showed a decreased motility. Also each of the mutants showed an impaired cytotoxicity and adherence to HeLa cell compared with the isogenic wild type strain. LD(50) increased by 10- and 11-fold in the V. vulnificus HAP3 and HAP2 mutant, respectively. These results suggest that the HAP proteins play important roles in polar flagellation and the virulence of V. vulnificus.

BACKGROUND/AIMS: Tuberculous meningitis is a common, occasionally fatal infectious disease of the central nervous system. We evaluated the diagnostic validity of weighted diagnostic index scores (WDIS), which have been suggested to aid in the diagnosis of adult patients with tuberculous meningitis, on the basis of simple clinical and laboratory findings. METHODS: The microbiological and clinical data of adult patients with either tuberculous or bacterial meningitis were reviewed retrospectively. Diagnostic validity and WDIS cut-off values were evaluated by receiver operating characteristic (ROC) curve analysis. RESULTS: A total of 77 cases were included: 47 with tuberculous meningitis and 30 with bacterial meningitis. For the diagnosis of tuberculous meningitis, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of WDIS suggested by Thwaites (cut-off value of < or =4) were 100, 90, 94 and 100%, respectively. Based on ROC curve analysis (area under ROC curve=0.993), a cut-off value of < or =3 was most appropriate for the diagnosis of tuberculous meningitis. The sensitivity and specificity of WDIS with a cut-off value of < or =3 were 100 and 93.3%, respectively. CONCLUSIONS: Our study demonstrated that WDIS are highly predictable and acceptable for the early diagnosis of tuberculous meningitis in Korea, based on our analysis of clinical and laboratory findings. A cut-off value of < or =3 showed the best diagnostic validity.

PURPOSE: Phocomelia is an extremely rare congenital anomaly of the upper extremity. There have been no clinical reports about phocomlia in Korea except for five birth reports. We present here the clinical features, classifications and surgical treatments of our phocomelia cases. MATERIALS AND METHODS: From January 1993 to August 2007, seven patients were diagnosed as having phocomelia in 9 upper extremities at our clinic. Surgical treatments were performed for five patients on their hand anomalies. We retrospectively reviewed the medical records and radiographs of our cases, and we tried to classify them by the previously suggested systems. We evaluated the functional improvement and measured the VAS scale for parental satisfaction with the operative outcomes. RESULTS: We could not find any problems during the fetal periods or any hereditary features. The bilaterally-affected patients also had deformities of the lower extremity, while the unilaterally-affected patients did not. We couldn't classify our cases according to the Frantz and O'Rahilly system. We found that the classifications suggested by Tytherleigh-Strong and Hooper (2003) and Goldfarb et al. (2005) could be promising alternatives for classification. One upper extremity was classified as type A, one as type B, and 7 as type C by Tytherleigh-Strong and Hooper's system. Using the Goldfarb's system, two upper extremities were classified as proximal radial longitudinal dysplasia, and seven were classified as proximal ulnar longitudinal dysplasia. Three patients who underwent pollicization showed opposition and tip pinch. Two patients who underwent syndactyly division could do lateral pinch. The VAS scale for parental satisfaction with the functional improvement averaged 8.2 postoperatively. CONCLUSION: The bilateral cases had different clinical features from unilateral ones. Phocomelia could not simply be classified by the Frantz and O'Rahilly system, and it may not be a true transverse intercalary deficiency. We could gain functional improvement after operations on the hand anomalies.
