Dermatofibrosarcoma protuberans is a rare, slowly growing, locally invasive spindle-cell tumor characterized by a protuberant cutaneous mass with a pronounced tendency to recur and by a prominent storiform histopathologic pattern'-'. We present a case of dermatofibrosarcoma protuberans with myxoid area on the chest of a 57-year-old man. The histopathological study showed a dermal tumor of uniform spindle-shaped cells with storiform pattern. Immunohistochemically, the tumor was stained positively to anti-CD34 antibody and negatively to anti-factor XIIIa antibody.

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.

Primary bronchial neoplasms in children, especially malignant lesions, are extremely rare. We report a case of a 10-year old boy with intermediate-grade mucoepidermoid carcinoma of the right intermediate bronchus, presenting as collapse and bronchiectasis after pneumonia. He was diagnosed by bronchoscopic biopsy. The lobectomy was performed. The patient is in good condition 1 year after operation. All reported cases of bronchial mucoepidermoid tumors in children had histologically low or intermediate grade(well differentiated) variety with a benign clinical course. The optimal surgical therapy for bronchial mucoepidermoid tumors is identical. There must be total removal of either mass with the sacrifice of as little normal lung as possible.

BACKGROUND: Propofol is an alternative to thiopental as an intravenous induction agent for cesarean section. It is also used as a sedative for supplementation of regional blockade during cesarean section. It has been reported that propofol relaxes not only vascular smooth muscle but also other smooth muscles. The aim of this study was to investigate the effect of propofol on rat uterine smooth muscle in an isolated preparation in the rat. METHODS: Uterine smooth muscle tissues were obtained from rats (n = 21). The muscle strips were suspended in tissue baths and isometric tension was recorded. After spontaneous or oxytocin induced activity had been accomplished in the buffer solution as a control, propofol (1 to 20microgram/ml) in fat emulsion was applied cumulatively to the bath and the effects were continuously recorded. RESULTS: In vitro, propofol induced a dose-dependent inhibition of spontaneous as well as oxytocin induced myometrial contractile activity. Propofol concentration of 1microgram/ml had no significant effects on the resting tension, active tention, and frequency of contraction developed by spontaneous and oxytocin induced uterine contractility. However, Complete muscular relaxations on spontaneous and oxytocin induced contractility were obtained at a concentration of 10microgram/ml and 20microgram/ml, respectively. CONCLUSIONS: Propofol inhibits spontaneous and oxytocin-induced uterine smooth muscle contractions in dose dependent pattern.

Urethral reconstruction is a problematic issue, thus its management can be challenging. Different methods using various materials were introduced for urethral reconstruction. The authors have made some changes in the groin flap surgery, affording more successful urethral reconstruction for defects of long urethra and penile soft tissue. A 45-year-old male requested both functional and cosmetic reconstruction of his defected penis, caused by an iatrogenic urethral injury and chronic infection following removal of paraffin self-injected on the penile shaft. The defect affected the full length of the penile urethra, corpus spongiosum, and prepuce. A groin flap was designed, measuring 28×10 cm. The most distal flap was utilized for the construction of the luminal surface of the neourethra; relaxed length measuring 8 cm, and the lumen wide enough. Competent external meatus and neourethra was confirmed by retrograde cystogram and the patient voided with sufficient urine caliber up to 2 years follow-up. This operative technique has advantages. Donor sites have non-hair bearing skin for the neourethra and minimal or almost not-recognizable donor site morbidity. After surgery, the patient was relieved from voiding difficulties combined with psychological stress. The author would like to introduce a unique approach for the urethral and ventral phalloplasty using the groin flap.

BACKGROUND: Postoperative sore throat (POST) is considered a usual complication after tracheal intubation, especially, thyroid surgery. Gabapentin is a widely studied multimodal perioperative drug, which can be used to treat acute postoperative pain. The primary endpoints of this study was a reduction of the incidence of POST at rest and during the swallowing movements after thyroid surgery. And the second endpoints was a reduction of the intensity of the POST after thyroid surgery. METHODS: Seventy-one patients that underwent elective thyroid surgery received either gabapentin (Neurontin(TM) 600 mg) or placebo, orally, one hour before anesthesia. The VAS scores and incidences of POST and adverse effects were determined at 1 hr, 6 hr, 12 hr, and 24 hr after surgery at rest and during swallowing movement. RESULTS: The gabapentin group (N = 36) showed a lower incidence of POST than the placebo group (N = 35) (47% vs. 78%, P = 0.038), and had significant lower VAS score at 6 and 24 hours after surgery in the resting state. However, during the movement, no intergroup differences were found in terms of the incidence of POST (83% vs. 91%, P = 0.305) or VAS score. Furthermore, no significant difference was observed between the two groups, in adverse effects. CONCLUSIONS: Gabapentin (Neurontin(TM) 600 mg) administered 1 hr before anesthesia reduced the intensity and incidence of POST during the resting state without a significant adverse event, during the 24 hr after thyroid surgery. However, gabapentin did not reduce the intensity and incidence of POST during the swallowing movement.

Gingivitis and periodontitis are infectious diseases in that microorganisms are the primary extrinsic cause of the diseases. the occurrence of gingivitis has been associated clearly with the presence of microorganisms at the disease site, and the histologic nature of the tissue involved is indicative of an inflammatory response induced by microorganisms. additional evidence for the microbial etiology of periodontal disease is that numerous antimicrobial agents are effective in reducing plaque accumulation and periodontal diseases. the purpose of this article is to analyze the antimicrobial effects of Pulsatilla koreana. Well-dried Pulsatilla koreana purchased from herbs distributor was ground and extracted into methanol(MeOH), ethylacetate(EtoAc), chlorform(CHCl3) and Butyl alcohol(BuOH). we have then applied each solution to the bacteria samples(Bacteroides forsythus, Streptococcus mutans, Streptococcus sanguis, Porphylomonas gingivalis, Actinobacillus actinomycetemcomitans, Eikenella corrodens, Prevotella intermedia, Actinomyces viscosus, Prevotella nigrescens, Rothia dentocariosa, Fusobacterium nucleatum, Pseudomonas aeruginosa, Staphylococcus aureus) collected from several organizations. To conduct susceptibility test(Kirby-Bauer method), plate contained each periodontopathic bacteria is spread extracted into methanol(MeOH), ethylacetate(EtoAc), chlorform(CHCl3) and Butyl alcohol(BuOH) and to measure the minimum inhibition concentration(MIC) of the bacteria against the solutions to ultimately determine antimicrobial effects of the solutions, insert bacteria sample into 20microliter/ml, 10microliter/ml, 5microliter/ml, 2.5microliter/ml of each solution and control group(not contained solution) 1. Solution extracted into methanol did not show clear zone against all bacteria samples. Only P. nigrescens, S. mutans and S. sanguis in soluton extracted into ethylacetate, S. mutans and S. anguis in solutions extracted into chlorform and Butyl alcohol showed clear zone against all bacteria samples. Solution extracted into Butyl alcohol showed clear zone against 13 types of bacteria, excluding P. gingivalis. 2. In Solution extracted into methanol, the bacteria samples grew in the highest concentrated plate, showing minimal variation from control group. 3. In Solution extracted into Butyl alcohol, S. aureus, P. intermedia, E. corrodens, A. actinomycetemcomitans, B. forsythus, P. gingivalis et al. showed decreased growth in the highest concentrated plate. P. auruginosa, R. dentocariosa, A. viscosus, P. nigrescens, S. mutans et al. showed decreased growth at MIC 20microliter/ml and S. sanguis showed decreased growth at MIC 10microliter/ml. 4. By analyzing the MIC level through considering the results from Kirby-Bauer method, Solution extracted into methanol did not reveal any antimicrobial effects and Solution extracted into Butyl alcohol showed the highest antimicrobial effects In conclusion, it can be used the extracts of Pulsatilla koreana as wide spectrum antimicrobial agent.

Craniosynostosis is defined as the premature fusion of one or more cranial sutures resulting in skull deformity. Characteristically, this disorder can cause diverse neurosurgical problems, as well as abnormal skull shape. Intracranial hypertension, hydrocephalus, Chiari malformation and neuropsychological dysfunction are the major neurosurgical concerns in children with craniosynostosis. In this review article, we investigate pathophysiology, characteristics and proper neurosurgical management of these neurosurgical issues, respectively.
