ABSTRACT

@#Acute pulmonary embolism (PE) is a common disorder with significant morbidity and mortality in patients who underwent pulmonary ground-glass nodules (GGN) resection. We should make efforts to increase surgeons' awareness of risk factors of PE and their understanding of the effectiveness of prevention strategies. Using the optimal risk assessment model to identify high-risk patients and give them the individualized prophylaxis. Early diagnosis and accurate risk stratification is mandatory to reduce the rates of PE, to decrease health care costs and shorten the length of stay. This article summarizes the risk factors, diagnostic process, risk assessment models, prophylaxis and therapy for the PE patients who underwent GGN resection.

ABSTRACT

@#Since December 2019, a novel coronavirus (2019-nCoV, SARS-CoV-2) pneumonia (COVID-19) outbreak has occurred in Wuhan, Hubei Province, and the epidemic situation has continued to spread. Such cases have also been found in other parts of the country. The spread of the novel coronavirus pneumonia epidemic has brought great challenges to the clinical practice of thoracic surgery. Outpatient clinics need to strengthen the differential diagnosis of ground glass opacity and pulmonary plaque shadows. During the epidemic, surgical indications are strictly controlled, and selective surgery is postponed. Patients planning to undergo a limited period of surgery should be quarantined for 2 weeks and have a nucleic acid test when necessary before surgery. For patients who are planning to undergo emergency surgery, nucleic acid testing should be carried out before surgery, and three-level protection should be performed during surgery. Patients who are planning to undergo emergency surgery in the epidemic area should be confirmed with or without novel coronavirus pneumonia before operation, and perform nucleic acid test if necessary. Surgical disinfection and isolation measures should be strictly carried out. Among postoperative patients, cases with new coronavirus infection were actively investigated. For the rescue of patients with novel coronavirus infection, attention needs to be paid to prevention and treatment and related complications, including mechanical ventilation-related pneumothorax or mediastinal emphysema, and injury after tracheal intubation.

ABSTRACT

@#Quality control of general thoracic surgery contains many links including the qualification and technical conditions of medical institutions, preoperative diagnostic system, surgery, postoperative management, pathological diagnosis and follow-up. Standards of quality control should be based on evidence-based medicine, and general rules with detailed criteria. As one of the core concepts of quality control, fine management is ought to strictly follow clinical practice guideline of thoracic surgery, to be clear with quality standards of each key link in clinical pathway, and to improve the clinical quality control system that combines self-evaluation and supervision and inspection.

ABSTRACT

@#With the development of thin section axial computed tomography scan, the detection rate of pulmonary ground-glass nodules (GGN) continues increasing. GGN has a special natural growth history: pure ground-glass nodules (PGGN) smaller than 10 mm can hold steady for a long term, surgery resection is unnecessary, patients need regular follow up. Larger part solid ground-glass nodules (PSN) with a solid component can be malignant early stage lung cancer, which requires early surgery intervention. Establishment of a standard definition of GGN growth, investments in the long term natural growth history of GGN, validation of the clinical, radiology and genetic risk factors would be beneficial for the management of GGN patients.

ABSTRACT

@#With the wide utilization of high-resolution computed tomography (HRCT) in the lung cancer screening, patients detected with pulmonary ground-glass nodules (GGNs) have increased over time and account for a large proportion of all thoracic diseases. Because of its less invasiveness and fast recovery, video-assisted thoracoscopic surgery (VATS) is currently the first choice of surgical approach to lung nodule resection. However, GGNs are usually difficult to recognize during VATS, and failure of nodule localization would result in conversion to thoracotomy or extended lung resection. In order to cope with this problem, a series of approaches for pulmonary nodule localization have developed in the last few years. This article aims to summarize the reported methods of lung nodule localization and analyze its corresponding pros and cons, in order to help thoracic surgeons to choose appropriate localization method in different clinical conditions.

ABSTRACT

Malaria and HIV are two of the most severe public health problems in Africa. However, epidemiological data on Bioko Island is scarce. To investigate the prevalence of malaria and HIV infections and assess association of malaria and HIV infections and possible confounding factors, we performed a cross-sectional survey of people of malaria-endemic Bioko Island, Equatorial Guinea. A cross-sectional study of 1 526 subjects was carried out to determine the prevalence of malaria and HIV infection in Malabo region hospital on Bioko Island. Questionnaires were administered and venous blood samples were drawn for malaria parasites and HIV detection. The prevalence of participants infected with malaria and HIV in this area were 13.8% and 6.6% respectively. The average prevalence of co-infection for malaria and HIV was 0.92%. HIV-infection was significantly associated with the age and gender. Malaria infections were significantly associated with the age. This study showed that the prevalence of HIV and malaria on Bioko Island was higher than expected, although the co-infection prevalence of malaria and HIV was low. The results also indicated that malaria and HIV infections lead to more public health risk to youngsters and women

ABSTRACT

Aims: The objective of this study was to synthesize and characterize the poly (acrylic acid) or PAA with different molecular architectures, use these polymers to formulate the cements with glass fillers, and evaluate the mechanical strengths of the formed cements. Materials and Methods: The novel poly (acrylic acid)s with different molecular architectures were synthesized via ATRP technique. The reaction kinetics was studied. The formed cements were evaluated using compression, diametral compression, and 3- point bending, fracture toughness, knoop hardness, and wear resistance tests. The experimental cement was also evaluated for its in vitro biocompatibility. Results: The results showed that either hyperbranched or star-hyperbranched polymer synthesis proceeds more slowly at the early stage but accelerates more quickly at the later stage than the star-shaped polymer synthesis. The higher the arm number and initiator concentration, the faster the ATRP reaction. It was also found that the higher the arm number and branching that the polymer had, the lower the viscosity of the polymer aqueous solution and the lower the mechanical strengths of the formed cement exhibited. The mechanical strengths of all three experimental glass-ionomer cements were very similar to each other but much higher than those of Fuji II LC. The aging study showed that all the experimental cements increased their CS continuously during 30 days, unlike Fuji II LC. This novel cement system was proven to be in vitro biocompatible because it showed no any noticeable cytotoxicity to human dental pulp cells and mouse 3T3 mouse fibroblasts.

ABSTRACT

OBJETIVO: A cirurgia torácica vídeo-assistida (CTVA) tem sido uma intervenção de escolha para o tratamento de pneumotórax espontâneo (PS) com bolha pulmonar. Nosso objetivo foi apresentar uma abordagem de CTVA uniportal unilateral para bulectomia bilateral e avaliar sua eficácia terapêutica. MÉTODOS: Entre maio de 2011 e janeiro de 2012, cinco pacientes foram submetidos a bulectomia bilateral por essa abordagem. Todos apresentavam PS bilateral. A TCAR pré-operatória mostrou que todos os pacientes tinham bolhas bilaterais no pulmão apical. As indicações cirúrgicas, os procedimentos de operação e os desfechos foram revisados. RESULTADOS: Todos os pacientes foram submetidos com sucesso a essa abordagem para bulectomia bilateral, sem complicações intraoperatórias. A mediana de tempo para a retirada do dreno torácico foi de 4,2 dias, e a mediana do tempo de hospitalização no pós-operatório foi de 5,2 dias. A mediana de seguimento pós-operatório foi de 11,2 meses. Um paciente teve recidiva de PE do lado esquerdo três semanas após a cirurgia e foi submetido a abrasão pleural. CONCLUSÕES: A bulectomia bilateral utilizando CTVA uniportal combinada com acesso contralateral ao mediastino anterior é tecnicamente confiável e promove desfechos favoráveis para pacientes com PS que desenvolvem bolhas bilaterais no pulmão apical. Entretanto, para a realização desse procedimento cirúrgico, são necessários cirurgiões com experiência em CTVA, instrumentos toracoscópicos longos, entre outras exigências.


OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has been a surgical intervention of choice for the treatment of spontaneous pneumothorax (SP) with lung bulla. Our objective was to introduce a uniportal VATS approach for simultaneous bilateral bullectomy and to evaluate its therapeutic efficacy. METHODS: Between May of 2011 and January of 2012, five patients underwent bilateral bullectomy conducted using this approach. All of the patients presented with bilateral SP. Preoperative HRCT revealed that all of the patients had bilateral apical bullae. We reviewed the surgical indications, surgical procedures, and outcomes. RESULTS: All of the patients were successfully submitted to this approach for bilateral bullectomy, and there were no intraoperative complications. The median time to chest tube removal was 4.2 days, and the median length of the postoperative hospital stay was 5.2 days. The median postoperative follow-up period was 11.2 months. One patient experienced recurrence of left SP three weeks after the surgery and underwent pleural abrasion. CONCLUSIONS: Bilateral bullectomy through uniportal VATS combined with contralateral access to the anterior mediastinum is technically reliable and provides favorable surgical outcomes for patients with bilateral SP who develop bilateral apical bullae. However, among other requirements, this surgical procedure demands that surgeons be experienced in VATS and that the appropriate thoracoscopic instruments are available.
