Abstract: Drainage by chest tube thoracostomy is widely used in treatment of early empyema thoracis in children, but drainage with antiseptic lavage-irrigation is more frequent in our context since the last 20 years. This study was to determine which was more effective in our experience comparing chest tube drainage with catheter antiseptic lavage-irrigation versus drainage by chest tube thoracostomy alone in the management of empyema thoracis in children. Patients and Methods: Demographic, clinical and microbiological data on children with thoracic empyema undergoing drainage by chest tube thoracostomy alone or with antiseptic lavage-irrigation were obtained from 2 thoracic surgical centers from September 2008 to December 2014. It was a retrospective study included 246 children (137 boys and 109 girls) who were managed for empyema thoracis at the author’s different department of surgery. Outcomes analysis with respect to treatment efficacy, hospital duration, chest tube duration, hospital costs, and need for subsequent procedures was analyzed and compared in the 2 groups. Results: Drainage of pus and antiseptic irrigation resulted in resolution of pyrexia with improvement in general condition in 85.82% of patients in group 1 and by tube thoracostomy alone in 73.95% in group 2. There are a significant difference in the length of hospital stay (p = 0.022), duration of chest tubes in situ (p = 0.040), treatment coast (p = 0.015) and outcome of stage 2 empyema disease (p = 0.037) between the 2 groups. Conclusion: it seems that chest tube drainage with antiseptic lavage-irrigation method is associated with a higher efficacy, shorter length of hospital stay, shorter duration of chest tube in situ, less cost and better outcome of stage 2 empyema diseases than a treatment strategy that utilizes chest tube thoracostomy alone.

Abstract: Cavernous lymphangioma of the chest wall is a very rare disease entity, and only a few cases have ever been documented in the literature. Cases of recurrent cavernous lymphangioma after surgical excision of a cystic lymphangioma on the same side of the chest wall are quite uncommon. We report a case of a 10-year-old girl, with a giant cavernous lymphangioma of the left lateral chest wall extending into the axilla, who had undergone surgical excision of a cystic lymphangioma 9 years earlier.

Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.74024
Abstract: Necrotizing fasciitis is an uncommon infection, but potentially lethal, especially when associated with systemic disorders such as diabetes. We report the case of a 35-year-old female with uncontrolled diabetes mellitus, presenting with edema of the neck, facial and left mammary gland, secondary to untreated dental infection, progressing to a full-blown necrotizing fasciitis in a short period of time with sepsis. The patient was managed with aggressive multidisciplinary medical and surgical treatment. Despite the technologic advances in diagnosis and treatment, complications still result with astounding high mortality. Clearly, the morbidity associated to this infection, even in diabetic patients, can be minimized if an early diagnosis and effective debridement are done.

Open Journal of Respiratory Diseases (OJRD) , 2016, DOI: 10.4236/ojrd.2016.62006
Abstract: Traumatic diaphragmatic rupture (TDR) is very rare in the pediatric age group. Because of its rarity and its coexistence with more injuries, the diagnosis is often delayed. Very little has been written about this condition in the pediatric age group. TDR, while uncommon, should be considered in cases of blunt thoracic trauma. All patients should undergo meticulous examination preoperatively. The clinical presentation and importance of making an accurate diagnosis and surgery is highlighted. We report a case of secondary spontaneous traumatic left-sided diaphragmatic rupture in a child that was managed by delayed surgical repair.

Abstract: Introduction: There has been limited experience with Open Heart Surgeries (OHS) in Sub-Saharan Africa. In west Africa especially in Mali, most fledgling centers are unable to overcome the myriad of challenges encountered in establishing OHS though there is a high prevalence of surgically correctable heart diseases. The aim of this paper is to review our initial experience of our first cases in developing OHS program and discuss the challenges and prospects that need to be overcome to further develop it. Methods: A total of 6 patients who underwent OHS during the first “cardiac mission” in July 2016 were included in this retrospective study. The medical records of the patients were examined and data on age, sex, diagnosis, EuroSCORE, type of surgery, cardiopulmonary bypass details, complications and length of hospital stay were extracted. Results: Six patients with a male to female ratio of 1, ages ranging between 12 and 35 years (mean of 22.5 ± 12 years) were studied. The mean of EuroSCORE was 6 ± 41. Pericardial patch closure of isolated atrial septal defect was performed in one patient. One patient had mitral valve repair for rheumatic mitral regurgitation consisting of chordal shortening with a tricuspid valvuloplasty. Three patients had mitral valve replacement with tricuspid valvuloplasty. Four patients had mitral valve replacement. Sixty-day mortality?was 0%. Conclusion: Safe conduct of open heart surgery in Mali Hospital setting is feasible. Grant financial aid is required for rapid growth of Open-Heart Surgery in this part of Sub-Saharan Africa.

Surgical Science (SS) , 2015, DOI: 10.4236/ss.2015.610062
Abstract: Internal jugular vein (IJV) ectasia is a rare benign disease. It commonly presents as a unilateral, soft, compressible neck swelling that mostly involves the right side. It is usually a childhood disease and believed to be of congenital origin. Accurate diagnosis from careful history, physical examination and radiological study can be made. We report here two cases of IJV ectasia in African adults with right lateral neck mass dilating when increase intrathoracic pressure. Because of its rarity, this entity is frequently ignored or misdiagnosed. This case report intends to stress the importance of keeping IJV ectasia as differential diagnosis in mind in case of lateral neck swellings to avoid invasive investigations and inappropriate treatment. The asymptomatic case management of IJV ectasia is conservative with long-term surveillance.
Very strong coupling in GaAs based optical microcavities
H. Zhang,N. Y. Kim,Y. Yamamoto,N. Na
Physics , 2012, DOI: 10.1103/PhysRevB.87.115303
Abstract: We show that when following a simple cavity design metric, a quantum well exciton-microcavity photon coupling constant can be larger than the exciton binding energy in GaAs based optical microcavities. Such a very strong coupling significantly reduces the relative electron-hole motion and makes the polaritons robust against phonon collisions. The corresponding polariton dissociation and saturation boundaries on the phase diagram are much improved, and our calculations suggest the possibility of constructing a room temperature, high power exciton-polariton laser without resorting to wide bandgap semiconductors.
Simulation of Unsteady Water Film Flow on Pelton Bucket  [PDF]
Shen Na
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.54B010
Abstract: In order to simulate the complicated unsteady flow in Pelton bucket, it is necessary to apply the animated cartoon approach. In this paper, a free jet and the inner surface of a bucket is described by boundary fitted grid (BFG) with non-orthogonal curvilinear coordinates. The water flow is discretized in space and time for CFD (computational fluid dynamics). The moving grids of water film are successfully projected onto the bucket’s inner surface by a projection algorithm. The visualization result of the jet landing on bucket’s surface and the unsteady flow in the rotating buckets in 3D verifies the effectiveness of the proposed method.
China’s Forensic System: Critical Comments on the “Latest” Flaw  [PDF]
Jiang Na
Chinese Studies (ChnStd) , 2014, DOI: 10.4236/chnstd.2014.33013
Abstract: The article will critically examine the fundamental flaws that have been newly discovered from the “latest” case studies. In recent decades, numerous miscarriages of justice have occurred in China mainly due to the insufficient or improper use of forensic evidence. Comments on the “latest” flaw will start from an overview of the notorious wrongful conviction in Case ZHANG Gaoping and ZHANG Hui whose exonerations in 2013 were based on the proper use of forensic techniques such as DNA testing. The case highlights the injustice that results when forensic evidence is ignored in favour of wrongful confessions extorted under police torture. It has been suggested that China’s several waves of forensic science reform cannot lead the current forensic identification to objective, fair or reliable forensic evidence. The “latest” founded flaw entrenched in its forensic system failed to be solved by technical, financial, administrative or legal progress only. In essence, the 2005 reform on forensic identification is flawed to its core, albeit being recently identified. This is primarily because in law forensic experts inside police can conduct identification to provide forensic evidence on cases investigated by police, which cannot ensure necessary check or balance to prevent or reduce forensic errors in practice.
