A seventeen-month-old male baby, who had received conventional biventricular repair for congenitally corrected transposition of the great arteries, underwent excision of supratricuspid ring. Although tricuspid valve annulus was marginally small on direct inspection in the operating theater, circumferential excision of supratricuspid ring alone completely relieved the right ventricular inflow obstruction.

A forty-three-year-old male patient was diagnosed with an acute abscess in the dorsum of the right hand. On the 5th day of conventional pharmacological therapy the patient was still suffering, and was referred to the Outpatient department (OPD) to evacuate and drain the abscess and treat the edema around the area with Hijama (wet cupping therapy, WCT). The hand abscess was successfully cured within a week using an integrative approach of wet cupping therapy together with conventional drug therapy.

Background: The generalized gamma distribution statistics constitute an extensive family that contains nearly all of the most commonly used distributions including the exponential, Weibull and log normal. A saturated version of the model allows covariates having effects through all the parameters of survival time distribution. Accelerated failure-time models assume that only one parameter of the distribution depends on the covariates. Methods: We fitted both the conventional GG model and the saturated form for each of its members including the Weibull and lognormal distribution; and compared them using likelihood ratios. To compare the selected parameter distribution with log logistic distribution which is a famous distribution in survival analysis that is not included in generalized gamma family, we used the Akaike information criterion (AIC; r=l(b)-2p). All models were fitted using data for 369 women age 50 years or more, diagnosed with stage IV breast cancer in BC during 1990-1999 and followed to 2010. Results: In both conventional and saturated parametric models, the lognormal was the best candidate among the GG family members; also, the lognormal fitted better than log-logistic distribution. By the conventional GG model, the variables "surgery", "radiotherapy", "hormone therapy", "erposneg" and interaction between "hormone therapy" and "erposneg" are significant. In the AFT model, we estimated the relative time for these variables. By the saturated GG model, similar significant variables are selected. Estimating the relative times in different percentiles of extended model illustrate the pattern in which the relative survival time change during the time. Conclusions: The advantage of using the generalized gamma distribution is that it facilitates estimating a model with improved fit over the standard Weibull or lognormal distributions. Alternatively, the generalized F family of distributions might be considered, of which the generalized gamma distribution is a member and also includes the commonly used log-logistic distribution.

An overdose of antihypertensive agents, such calcium channel blockers (CCBs) and angiotensin II receptor blocker (ARBs), and the antihyperglycemic agent, metformin, leads to hypotension and lactic acidosis, respectively. A 40-year-old hypertensive and diabetic man with hyperlipidemia and a weight of 110 kg presented to the emergency room with vomiting, dizziness, and hypotension following an attempted drug overdose suicide with combined CCBs, ARBs, 3-hydroxy-3-methylglutaryl-coemzyme A reductase inhibitors, and metformins. A conventional medical treatment initially administered proved ineffective. The treatment was then changed to simultaneous extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT), which was effective. This shows that simultaneous ECMO and CRRT can be an effective treatment protocol in cases of ineffective conventional medical therapy for hypotension and lactic acidosis due to an overdose of antihypertensive agents and metformin, respectively.

배경: 저자들은 FLT3-ITD (fms-like tyrosine kinase-internal tandem duplication) 돌연변이의 정량 및 반복 염기 길이를 동시에 측정하는 정량 절편 분석법(fragment analysis)의 민감도를 평가하고, 분석적 성능을 검증하였다. 방법: FLT3-ITD 돌연변이의 정량과 수는 절편분석법으로 측정하였다. 변이 대립유전자와 정상 대립유전자를 혼합한 계대희석 표준물질로 절편 분석법, 일반 PCR법, 염기서열분석법의 FLT3-ITD 변이 검출한계를 측정하였다. 정상 공여자 50검체를 이용하여 특이도를 평가하였다. 급성골수성백혈병 환자의 481검체에 대하여 절편 분석법과 일반 PCR법으로 검사를 시행하고 그 결과를 비교 분석하였다. 결과: 절편 분석법의 돌연변이 최소 검출 농도는 5%였으며, 일반 PCR 검사법과 직접염기서열분석법은 각각 10%, 20%의 결과를 보였다. 급성골수성백혈병 환자의 481 검체를 분석한 결과, FLT3-ITD는 40.1% (193/481)에서 양성이었다. 변이 대립유전자의 정량값은 1.7-94.1% (중앙값 28.2%)로 다양하였으며, 반복 염기의 길이의 범위는 14bp-153 bp (중앙값 49bp)였다. 일반 PCR 검사법과 비교한 결과 방법간 일치도는 97.7% (470/481)였다. 절편 분석법이 일반 PCR 검사법에 비해 더 높은 민감도를 보였고, 11건의 돌연변이가 더 검출되었다. 이 중 7검체는 변이 대립유전자의 양이 10% 미만으로 일반 PCR 검사에서 검출되지 않았다(3.3-9.5%). 또 다른 불일치 세 검체에서는 PCR inhibitor의 영향으로 일반 PCR 방법에서 위음성 결과를 보였으며, 다른 한 검체는 돌연변이 중복 길이가 14 bp로 매우 짧아 일반 PCR에서 정상 밴드와 구별되지 않는 경우였다. 결론: 본 연구에서 저자들이 사용한 절편 분석법은 FLT3-ITD 돌연변이의 정량값과 중복된 길이를 동시에 측정할 수 있는 검사법으로, 민감하고 정확하여 급성골수성백혈병 환자에서 FLT3-ITD의 진단 및 추적 검사에 유용할 것으로 기대된다.

The purpose of this study was to evaluate the effectiveness and safety of acupotomy for the treatment of patients with knee osteoarthritis. There were 9 databases searched to retrieve randomized controlled trials until August 3, 2019 regarding acupotomy versus conventional Western medicine, conventional Western medicine treatment with and without acupotomy, and Korean medicine treatment with and without acupotomy, and meta-analysis was performed. Of 303 potentially relevant studies retrieved, 43 were systematically reviewed. All studies were conducted in China. Effective rate, visual analogue scale, and Western Ontario and McMaster Universities Osteoarthritis index were used as the evaluation scales. The Ashi point was selected most frequently. In all studies, the intervention group was more effective than the control group. Meta-analysis revealed that acupotomy showed statistically significant beneficial results. Although acupotomy had a beneficial effect on knee osteoarthritis, the risk of bias of the included studies was not low. The majority of the results from the evaluation scales used were highly heterogeneous (> 50%) which reduced confidence in the estimation of effect, or had a small sample size. Further clinical research and development is required in the future.

Background Fingertip injuries are the most common type of traumatic injury treated at emergency departments and require prompt and adequate interventions for favorable wound survival outcomes. Hyperbaric oxygen (HBO₂) therapy is well known for its many positive effects on wound healing. We hypothesized that treatment with HBO₂ would improve the graft survival outcomes of amputated fingertip injuries treated with composite grafts. Methods This retrospective observational study included fingertip amputations that were treated between January 2013 and December 2017. A conventional group and an HBO₂ therapy group were statistically compared to evaluate the effect of HBO₂ treatment. Graft survival was categorized as either success or failure. Results Among 55 cases (digits), 34 digits were conventionally treated, while 21 digits were treated with HBO₂. No statistically significant differences were observed between the groups with regard to general characteristics. Among patients with guillotine-type injuries, the composite graft success rate was statistically significantly higher in the group that received HBO₂ therapy than in the conventional group (P=0.0337). Overall, the HBO₂ group also demonstrated a statistically significantly shorter healing time than the conventional group (P=0.0075). As such, HBO₂ treatment facilitates composite graft survival in cases of fingertip injury. Conclusions HBO₂ treatment was associated with an increased composite graft survival rate in guillotine-type fingertip injuries and reduced the time required for grafts to heal.

Background: Some patients show favorable changes in the descending aortic false lumen after conventional repair of acute type A dissection, although the incidence of favorable changes has been reported to be low. We aimed to investigate the incidence of positive postoperative changes in the false lumen and the factors associated with positive outcomes. Methods: In 63 patients who underwent surgery for type A acute dissection as well as serial computed tomography (CT) scanning, morphological parameters were compared between the preoperative, early postoperative (mean interval, 5.4 days), and late CT scans (mean interval, 31.0 months) at three levels of the descending thoracic aorta. Results: In the early postoperative CT images, complete false lumen thrombosis and/or true lumen expansion at the proximal descending aorta was observed in 46% of the patients. In the late images, complete thrombosis or resolution of the proximal descending false lumen occurred in 42.9% of the patients. Multivariate analysis found that juxta-anastomotic false lumen thrombosis was predictive of favorable early changes, which were in turn predictive of continuing later improvement. Conclusion: Even after conventional repair without inserting a frozen elephant trunk, the proximal descending aortic false lumen showed positive remodeling in a substantial number of patients. We believe that the long-term prognosis of type A dissection can be improved by refining surgical technique, and particularly by avoiding large intimal tears at the anastomosis site during the initial repair.
