Endometriosis in the abdominal wall following Cesarean section is one of the very rare condition among the extrapelvic endometriosis. Although benign, endometriosis possesses the unique ability to invade tissue and to disseminate or metastasize by hematogeneous, lymphatic route, or direct implantation. We reported the case with brief review of the literature.

PURPOSE: This study was performed to evaluate the efficiency of Platelet-rich plasma (PRP) for acceleration of bone healing process on allograft transplantation after curettage in benign bone tumor. MATERIALS AND METHODS: From December 2007 to February 2009, twenty-one patients who had benign bone tumor and underwent allograft transplantation after curettage were evaluated. Mean follow-up period was 14.6 months (range, 12-26 months). We compared with 13 cases of PRP group and 8 cases of non-PRP group in terms of size of lesion, bone resorption, amount of applied PRP and complications. The mean age at surgery was 23.6 years (range, 4-73 years). The most common diagnosis was simple bone cyst (7) followed by enchondroma (4), giant cell tumor (3), undifferentiated benign bone tumor (3) and so on. RESULTS: The mean size of lesion was 33.5 cm3 (range, 2.3-181.9 cm3) (29.4 cm3 in PRP group and 40.2 cm3 in non-PRP group). The mean volume of injected PRP was 7.4 cc (range, 3-12 cc). Bone union started at 3.0 months (range, 1.5-5.8 months) in PRP group and 5.3 months (range, 4-8 months) in non-PRP group. Three cases for each group were excluded due to recurrence and pathologic fracture. One patient had febrile episode 3 weeks later after surgery which subsided with antibiotics. CONCLUSION: The PRP could accelerate bone union in allograft transplantation after curettage of benign bone tumor. Furthermore, we expect that PRP can accelerate bone union in fracture or non-union.

In May 2011, five consecutive gastroenteritis outbreaks were reported at schools in Gyeonggi-do. Epidemiological inspection revealed that one food manufacture company provided 'Kimchi', a traditional Korean side-dish, to these five schools for catering services. Fecal specimens were collected from students and food-handlers to determine causative viral agents. Norovirus genogroup GI was detected from 58 samples out of total 239 specimens by reverse-transcription (RT)-PCR, whereas norovirus GII was found only from one sample. Epidemiological studies also revealed that the Kimchi was processed using groundwater in the food manufacture company. Four groundwater samples were collected from the company and around the area. Norovirus GI was detected from three samples. To determine the norovirus genotypes of positive specimens from clinical and groundwater samples, sequencing and phylogenetic analyses were performed. The genogroup GI from 58 clinical and three groundwater samples and the GII from one food-handler were identified as norovirus GI.3 and GII.18, respectively. Sequence alignment analysis with norovirus GI.3 isolates revealed that identity between clinical and groundwater samples was over than 99.1% in nucleotide level. In conclusion, norovirus GI.3-contaminated groundwater caused the gastroenteritis outbreaks of five schools, through Kimchi. This molecular epidemiological study was an important report in Korea that clearly identified all transmission routes of norovirus GI.3.

4.Autogenous fresh demineralized tooth graft prepared at chairside for dental implant.
Maxillofacial Plastic and Reconstructive Surgery 2015;37(2):8-
BACKGROUND: This study aimed to evaluate the clinical usefulness of autogenous fresh demineralized tooth (auto-FDT) graft prepared at the chairside for alveolar bone grafting during dental implant surgery. METHODS: In total, 38 patients requiring both tooth extraction (for endodontic or periodontal reasons or third molar extraction) and alveolar bone regeneration for dental implant placement were included. Within 2 h after clean extraction, the teeth were prepared at the chairside to serve as bone graft material. In the same sitting, blocks or chips of this graft material were used to reconstruct defects at the osteotomy site simultaneously with or before implant placement. Twelve months after prosthesis fabrication and placement, the clinical findings and implant success rates were evaluated. Histological studies were randomly conducted for selected cases. RESULTS: Clinical evaluation showed favorable wound healing with minimal complications and good bone support for the implants. No implant was lost after 12 months of function following prosthetic rehabilitation. Histological examination revealed new bone formation induced by the graft material. CONCLUSIONS: Chairside preparation of autogenous fresh demineralized teeth after extraction can be a useful alternative to the use of autogenous bone or other graft materials for the immediate reconstruction of alveolar bone defects to facilitate subsequent implant placement.

For comminuted shaft fracture of clavicle, the operative goal, aside from sound bone healing without complications of direct reduction, is maintenance of the original length in order to maintain the normal biomechanics of adjacent joint. Our bridge plating technique utilizing distraction through a lumbar spreader was expected to be effective for restoring clavicular length with soft tissue preservation. However, there are two disadvantages. First, there is more exposure to radiation compared to conventional plating; and second, it is difficult to control the rotational alignment. Despite these disadvantages, our technique has important benefits, in particular, the ability to preserve clavicular length without soft tissue injury around the fracture site.

6.Rhabdomyolysis after Lamotrigine Poisoning: A Case report.
Journal of The Korean Society of Clinical Toxicology 2008;6(2):142-145
Lamotrigine is a newer anti-epileptic drug for adjunctive treatment of refractory epilepsy, partial seizures, generalized tonic-clonic seizures, and bipolar disorder. Lamotrigine overdose causes serious central nervous and cardiovascular problems, but reports are uncommon. Few lamotrigine overdoses have been described because anti-epileptic drug use is limited and usually used with combination of other anti-epileptic drugs. In addition, most patients visit emergency departments with multi-drug overdoses, so few cases of lamotrigine poisoning alone exist. We had a female patient visit our emergency department a couple of hours after a lamotrigine overdose treated with intravenous hydration and urine alkalization by NaHCO3. She recovered successfully without any evidence of renal injury. However, she developed profound rhabdomyolysis, a previously unreported complication of this medication. We suggest that serial creatine kinase levels should be measured after lamotrigine poisoning.

PURPOSE: Recently, urine reflux into prostate during abnormal micturition has been proved and suggested to be an important pathogenetic factor that evoked the symptoms of prostatitis syndrome. The evaluation of voiding dysfunction in these patients may give the useful information to select the treatment methods or the next step of study. The objectives of this study was to evaluate the usefulness of voiding symptom score and uroflowmetry as the screening methods for patients with nonbacterial prostatitis syndrome. MATERIALS AND METHODS: For patients with prostatitis syndrome, evaluations of urine, prostatic secretion, voiding symptom scores(IPSS: international prostate symptoms score), and uroflowmetry were performed. Patients were divided into 3 groups according to the patterns of uroflow curve[type N; normal bell shape with Qmax(maximal flow rate) > 20ml/sec, type I; irregular shape, regardless of Qmax, type P; plateau shape with Qmaxf15ml/sec]. For patients with cutie patterns of type I and p, G-blockers were tried initially for 1-2 months and the effectiveness of o-blockers according to the changes of IPSS, Qmax and patterns of uroflow cutie was estimated. Patients with the pattern of type N and non-responders to o-blockers were further investigated to rule out any other cause. RESULTS: Among total 64 patients, 55 patients(86%) showed the abnormal uroflow cuties(Type I or P). 34(61.8%) of these 55 patients responded to alpha-blockers with changes of IPSS from 18.3 to 8.1(p<0.001) and of Qmax from 13.gm1/sec to 20.0ml/sec(p<0.001). The response to o-blockers was expected highly in group of type I with more than 10m1/sec of Qmax and less than 20points of IPSS(14.7folds). Of the 9 of type N patients, 6 were revealed to have idiopathic detrusor instability and 18 of 21 non-responders to alpha-blockers were diagnosed to have the bladder neck obstruction. CONCLUSIONS: The results that the effectiveness to o-blockers and the possibility of other disease could be characterized by IPSS and uroflowmetry suggest IPSS and uroflowmetry may be the useful screening methods for patients with prostatitis syndrome.

9.Activated Rac1 regulates the degradation of IκBα and the nuclear translocation of STAT3–NFκB complexes in starved cancer cells.
Experimental & Molecular Medicine 2016;48(5):e231-
In several human tumors, signal transducer and activator of transcription 3 (STAT3) and nuclear factor κB (NFκB) are activated and interact; how these STAT3–NFκB complexes are transported to the nucleus is not fully understood. In this study, we found that Rac1 was activated in starved cancer cells and that activated Rac1 coexisted with STAT3 and NFκB. Rac1 knockdown and overexpression of the dominant-negative mutant Rac1N19 inhibited the degradation of IκBα, an inhibitor of NFκB. MG132, an inhibitor of the ubiquitin proteasome pathway, increased the amount of non-phosphorylated IκBα, but not serine-phosphorylated IκBα, indicating that IκBα degradation by Rac1 in starved cancer cells is independent of IκBα serine phosphorylation by IKK. Rac1 knockdown also inhibited the nuclear translocation of STAT3–NFκB complexes, indicating that this translocation requires activated Rac1. We also demonstrated that the mutant STAT3 Y705F could form complexes with NFκB, and these unphosphorylated STAT3–NFκB complexes translocated into the nucleus and upregulated the activity of NFκB in starved cancer cells, suggesting that phosphorylation of STAT3 is not essential for its translocation. To our knowledge, this is the first study demonstrating the crucial role of Rac1 in the function of STAT3–NFκB complexes in starved cancer cells and implies that targeting Rac1 may have future therapeutic significance in cancer therapy.

PURPOSE: This study investigates the effectiveness of FK-506, a new immunosuppressive agent for in preventing the rejection of limb allo-transplants in rats. MATERIALS AND METHODS: Inbred strain Lewis (RT1l) were used as donors and Brown Norway (RT1n) as recipients for limb allotransplan-tation. The experimental animals were divided into four groups; group I: untreated allografts, group II: allografts receiving FK-506 1mg/kg/day for 5-12 days (n=6), group III: 2 mg/kg/day for 15 days (n=6), group IV: single dose of 10 mg/kg (n=3), immediately. Rejection signs, mean survival time of limbs and histologic analysis (by the muscle grading system of Buttemeyer et al.) were evaluated. RESULTS: The mean survival time in group I was 3.5 +/-1.04 days, in group II 7.17 +/-3.43 days, in group III 25.5 +/-12.01 days and in group IV 16.33 +/-8.08 days. FK-506 prolonged the survival time of limbs significantly in a dose-dependent manner. Histologic examination revealed that group II was grade II (n=2) and grade III (n=1); group III was grade I (n=2); and group IV was grade I (n=1) and grade II (n=1). CONCLUSION: These results demonstrate the unique effects of FK-506 upon preventing graft rejection and prolonging limb survival allo-grafts in rats.
