We report herein our surgical experience of Hartmann's procedure reversal using laparoscopic technique in a 72-year-old woman who underwent Hartmann's procedure for an obstructing sigmoid colon cancer 6 month earlier. The purposes of this report are to describe our technique of laparoscopic reversal of Hartmann's procedure, to introduce several technical tips in avoiding pitfalls, and to review its safty and efficacy. In brief, the colostomy was freed from the abdominal wall using a conventional technique, then a center rod and an anvil of a circular stapler were inserted into the colon. CO2 insufflation was performed through this insertion. Using a five-cannula technique, rectal stump was mobilized, then colorectal anastomosis was performed laparoscopically via a transanal stapled approach. The operating time was 130 minutes and blood loss was 50 ml. There were no intra- and postoperative complications. Up to now, with a 4-month follow-up period, the patient has been well without having any problems associated with this operation

A 6-day-old female infant had generalized superficial pustules which evolved into pigmented maucles, many of which had a peripheral collarvtte of scale. Histopsthologic stadies showed intracormeal aggregates of neutrophils. The appearance of the lesions and histopathologic finding fitted transient neonal pustular melanosis.

Extraskeletal bone-forming lesions are myositis ossificans, fibrodysplasia(myositis) ossificans progressiva, and extraskeletal osteosarcoma. It is of paramount importance to clearly distinguish these lesion from extraskeketal osteosarcoma. Myositis ossificans, by far the most common among these lesions, is a benign, ossifying process that is generally solitary and well circumscribed. It is found most commonly in the musculature, but it may also occur in other tissue, especially in tendons and subcutaneous fat. It occur as the result of various kinds of soft tissue injury(surgical scars, burns, dislocation of joints etc.) and also observed in patients with tetanus, in paraplegics secondary to traumatic spinal injury. Although there is general agreement that myositis ossificans is a nonprogressive benign process without nerplastic potential, its pathogenesis is still poorly understood.We experienced a myositis ossificans associated with chronic, extensive pressure sore in patient with paraplegia secondary to spinal injury.

Taurodontism is an anomaly characterized by a long and broad pulpal cavity and consumed apical location of the furcation area. This study aimed to determine the prevalence of taurodontism in deciduous molars based on digital panoramic radiographs of children. The study was performed on a sample of panoramic radiographs taken from 2,473 Korean children who visited the department of pediatric dentistry, Yonsei University Dental Hospital between Nov. 2005 and Mar. 2018. Taurodontism was mainly categorized by Daito’s method. Using panoramic radiographs, taurodontism was also categorized into mesotaurodontism, hypotaurodontism, and hypertaurodontism. Mesotaurodontism was the most prevalent type. A total of 2,473 panoramic radiographs were evaluated. The prevalence of taurodontism was 5.7% in general, 51.5% in the left quadrant, 48.5% in the right quadrant, 6.3% in the maxilla, and 93.7% in the mandible. The distribution of taurodontism stratified by gender showed a higher prevalence in males. This is a comprehensive study on the prevalence of taurodontism in children using the largest sample size to date.

BACKGROUND: It is known that QT dispersion represents asynchronous repolarization of ventricle which is related to ventricular fibrillation. The incidence of ventricular arrhythmia is increased after acute myocardial infarction. So this study compared QT dispersion and other repolarization indexes for detection of asynchronous repolarization in acute myocardial infarction. We also investigated which portion of repolarization is the key portion of the asynchrony. METHODS: In 37 acute myocardial infarction patients and 38 angina patients dispersion of QT, JT, JTpeak and QTpeak were measured. We also measured maximum adjacent dispersion of same parameters in precordial leads. In 20 survived patients and 17 dead patients after acute myocardial infarction were also compared. We also investigated correlation of PVC's on Holter monitoring with these repolarization parameters. RESULTS: 1) All ventricular repolarization indexes(QT, QTc, JT, JTpeak, QT peak and TpeakTend dispersion) were significantly increased in acute myocardial infarction group than compared with those of angina group(p<0.05). 2) Maximal precordial dispersion(QT, QTc, JT, JTpeak and QTpeak) were also significantly increased in acute myocardial infarction group than angina group(p<0.05). 3) Dead patient group after myocardial infarction showed significantly increased QTc and TpeskTend dispersion compared with those of survived patient group(p<0.05). 4) Multivariate linear correlation showed that TpeakTend dispersion and JT dispersion was correlated with QT dispersion. CONCLUSIONS: There were asynchronous myocardial repolarization changes in acute myocardial infarction. Our study demonstrated that T wave change was major determinant of dispersion of myocardial repolarization.

PURPOSE: The authors evaluated the differences between K-wires and Cannulated screw, plate for fixing the proximal metatarsal chevron osteotomy of moderate and severe hallux valgus. MATERIALS AND METHODS: There were 62 patients (79 feet) who were moderate and severe degree hallux valgus according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity. We divided the patients into 4 groups, Two K-wire fixed group as A, one cannulated screw fixed group as B. Two cannulated screw fixed group as C, Plate fixed group as D, Group A were patients (26 feet) and Group B were patients (9 feet), Group C were patients (31 feet) and Group D were patients (13 feet). Preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured for each patient. ANOVA test and Student t-test were done for statistical analysis. RESULTS: Mean follow up period was 43.8 months (range: 12~82 months). Preoperative mean IMA was 16.4+/-3.5, 17.7+/-11.3, 17.3+/-5.9 and 16.6+/-2.3 degrees in respectively group A, B, C, D. Immediate postoperative mean IMA was 5.6+/-3.4, 7.3+/-4.4, 7.6+/-4.4 and 6.7+/-2.8 degrees in respectively group A, B, C, D. The final mean IMA was 8.9+/-4.5, 15.2+/-7.5, 10.3+/-4.4 and D 7.7+/-3.5 degrees in respectively group A, B, C, D. There were significant statistical increase in final mean IMA of group B and C (p<0.05). CONCLUSION: The IMA was significantly increased in the group which used one or two cannulated screw for fixation on follow up, therefore more caution should be needed when using one or two cannulated screw fixation technique after proximal chevron osteotomy.

Purpose: To investigate the long-term clinical outcomes of transplanted amniotic membrane in patients who underwent permanent amniotic membrane transplantation (P-AMT) on cornea. Methods: From April 2014 to March 2021, medical records and digital photographs of 68 patients (72 eyes) who underwent P-AMT were analyzed retrospectively. The duration of complete re-epithelization of cornea and wearing therapeutic contact lense (T-lens) after surgery were investigated, the size of preserved amniotic membrane (AM) excluding the melted portion was analyzed using the Image J program every year up to 6 years after surgery, and it was compared by dividing into a single-layer group and a double-layer group. In addition, when the AM melts, the cause, time, and related factors of melting were analyzed. Results: The average duration to complete re-epithelialization after surgery was 12.2 ± 11.0 days, and T-lens were worn on average up to 8.7 ± 8.5 months after surgery. In total group, the average ratio of preserved AM annually up to 6 years after surgery was 94.9%, 94.3%, 97.8%, 96.4%, 95.8%, 91.6% respectively, and there was no significant difference between the single-layer group and the double-layer group. AM melting appeared in 38.9% (28 eyes) of the total group, and melting was first observed on average 16.4 ± 17.2 months after surgery. The formation and rupture of bullae was the most common cause of melting at 71.4% (20 eyes), and there were no statistically significant related factors involved in the formation of bullae. Conclusions In the case of P-AMT performed in various diseases of the cornea, the transplanted AM is partially melt but considered to be well preserved up to 6 years after surgery to form a stable ocular surface.
