Investigation and Ethical Consideration of Perioperative Complications in Patients with Liver Transplantation / 中国医学伦理学

To explore the prevention and treatment of perioperative complications of adult liver transplantation patients from the perspective of ethics, and carry out ethical thinking in order to provide theoretical support. Through a cross-sectional study, 189 patients selected by strict admission criteria who received liver transplantation in the department of hepatobiliary surgery of the First Affiliated Hospital of Xi’an Jiaotong University from January 2018 to May 2019, to explore the incidence and ethical problems of perioperative complications in adult liver transplantation. The results showed that 87 patients had complications among 189 patients, the incidence was 46.03%. Among them, 28 patients with pleural effusion, the incidence was 14.81%; 15 patients with biliary complications, the incidence was 7.94%; 14 patients with diabetes mellitus, the incidence was 7.41%. The incidence of complications after liver transplantation is high, mainly including pleural effusion, biliary complications and diabetes mellitus. Thus, the prevention and intervention from the perspective of nursing ethics is worth exploring.

Pharmaceutical care for rare ADR in a patient with ALK-positive non-small cell lung cancer induced by alectinib / 中国药房

OBJECTIVE To provide reference for safe drug use in patients with anaplastic lymphoma kinase （ALK）-positive non-small cell lung cancer （NSCLC）. METHODS Clinical pharmacists participated in the diagnosis and treatment of a patient with ALK-positive NSCLC who developed bilateral pleural effusion and hemolytic anemia after taking alectinib； regarding symptoms such as pleural effusion and hemolytic anemia in the patient， clinical pharmacists investigated the patient’s history of medication and disease， as well as potential drug interaction； to consider the correlation between the patient’s use of alectinib and the duration of pleural effusion and hemolytic anemia， clinical pharmacists suggested that clinical doctors discontinued alectinib and used reduced dose treatment after the pleural effusion improved， but the patient suffered from bilateral pleural effusion and hemolytic anemia again； after evaluating the correlation between alectinib and bilateral pleural effusion and hemolytic anemia using the Naranjo’s assessment scale， clinical pharmacists recommend permanent discontinuation of alectinib and jointly recommend replacement with ensartinib with clinical physicians. RESULTS Physicians adopted the suggestions of clinical pharmacists. The pleural effusion subsequently regressed and hemolytic anemia improved after replacing the drug. The correlation between alectinib and bilateral pleural effusion and hemolytic anemia was confirmed. CONCLUSIONS Clinical pharmacists participate in pharmaceutical monitoring of ALK-positive NSCLC patients， assist clinical doctors in developing personalized medication recommendations， and ensure the safety of patient medication.

Biliotórax: una entidad rara para un diagnóstico frecuente. Un reporte de caso / Bilothorax: a Rare Entity for a Frequent Diagnosis. A Case Report

Introducción: El biliotórax es una condición infrecuente definida por la presencia de bilis en el espacio pleural. Actualmente, hay alrededor de 70 casos descritos en la litera-tura. Sigue siendo relativamente desconocido, por lo tanto, poco sospechado. Esta entidad suele ser el resultado de una lesión iatrogénica, a menudo secundaria a cirugías o traumatismos del tracto biliar, que conduce a la formación de una fístula pleurobiliar.

Introduction: Bilothorax is a rare condition defined by the presence of bile in the pleural space. Currently, there are around 70 cases described in the literature. It remains relatively unknown and, therefore, little suspected. This entity is usually the result of an iatrogenic injury, often secondary to surgery or trauma to the biliary tract, leading to the formation of a pleurobiliary fistula

Manejo conservador del neumotórax oculto en trauma

Introducción: El neumotórax oculto (NTXO) se encuentra hasta en el 15% de los traumatismos torácicos. Existen antecedentes del manejo conservador de esta patología (sólo observación), aunque su práctica continúa siendo discutida, especialmente, en traumatismos penetrantes. El objetivo de este trabajo es describir nuestra experiencia en el manejo conservador del NTXO. Materiales y Método: Estudio de cohorte retrospectivo realizado durante un período de 3 años en un Hospital de Trauma nivel I. Se incluyeron pacientes con traumatismo torácico (cerrado o penetrante) con NTXO. Se dividieron en dos grupos (conservados o drenados), realizándose una comparación de su evolución. Resultados: En 3 años fueron admitidos con traumatismo torácico 679 pacientes. De 93 pacientes con NTXO, 74 (80%) fueron conservados inicialmente y 19 (20%) tratados con drenaje pleural. Dos (3%) presentaron progresión del neumotórax en el seguimiento radiológico (conservación fallida). No se registraron complicaciones relacionadas con la ausencia de drenaje pleural. Las complicaciones y estancia hospitalaria fueron menores en el grupo de manejo conservador. Conclusión: Pacientes con NTXO por traumatismo de tórax (cerrado o penetrante), sin requerimiento de ventilación asistida y hemodinámicamente estables, pueden manejarse de manera conservadora con un monitoreo cercano durante 24 horas en forma segura, con menor tasa de complicaciones y de estancia hospitalaria.

Background: Occult pneumothorax (OPTX) is found in up to 15% of chest injuries. There is a history of conservative management of this pathology (only observation), although its practice continues to be discussed, especially in penetrating trauma. The objective of this paper is to describe our experience in the conservative management of OPTX. Materials and Method: Retrospective cohort study conducted over a 3-year period at a level I Trauma Center. Patients with thoracic trauma (blunt or penetrating) with OPTX were included. They were divided into two groups (preserved or drained) comparing their evolution. Results: Over a 3-year period 679 patients were admitted with chest trauma. From 93 patients with OPTX, 74 (80%) were initially preserved and 19 (20%) drained. Two patients (3%) presented pneumothorax progression in the follow-up imaging. There were no complications related to the absence of pleural drainage. Complications and hospital stay were lower in the conservative management group. Conclusion: Patients with OPTX due to chest trauma (blunt or penetrating), without requiring assisted ventilation and hemodynamically stable, can be safely conservative managed with close monitoring for 24 hours, with a lower rate of complications and hospital stay.

Características clínicas, diagnóstico e tratamento de mulher com síndrome de Meigs: relato de caso e revisão narrativa / Clinical characteristics, diagnosis and treatment of a woman with Meigs syndrome: case report and narrative review

O objetivo deste estudo é descrever o caso de mulher com síndrome de Meigs e apresentar a revisão narrativa sobre o tema. Paciente do sexo feminino, 30 anos, nulípara, encaminhada ao hospital por massa anexial e história prévia de drenagem de derrame pleural. Evoluiu com instabilidade hemodinâmica por derrame pleural hipertensivo à direita, sendo submetida a drenagem torácica, com citologia do líquido negativa. Após, foi submetida a laparotomia: realizada salpingo-ooforectomia esquerda. A congelação e a análise histopatológica diagnosticaram fibroma ovariano. A citologia ascítica foi negativa. CA-125 elevado, presença de derrames cavitários e exame de imagem suspeito podem mimetizar um cenário de neoplasia maligna de ovário em estágio avançado. Entretanto, na síndrome de Meigs clássica, o tratamento é cirúrgico, sendo o diagnóstico obtido por meio da análise histopatológica do tumor ovariano. O manejo da síndrome de Meigs clássica é cirúrgico e, após a remoção do tumor, o derrame pleural e a ascite desaparecem.

To describe a case of Meigs syndrome and present a narrative review of the condition. Female patient, 30 years old, nulliparous, referred to the hospital due to an adnexal mass and a previous drainage of pleural effusion. She developed hemodynamic instability due to a hypertensive right pleural effusion being submitted to chest drainage, with negative cytology of the fluid. She underwent laparotomy: Left salpingo-oophorectomy was performed and frozen section and histopathological analysis diagnosed an ovarian fibroma. Ascites cytology was negative. Elevated CA-125, presence of cavitary effusions, suspicious imaging exam can mimic a scenario of ovarian cancer at an advanced stage. However, in classical Meigs syndrome, treatment is surgical, and the diagnosis is obtained through histopathological analysis of the ovarian tumor. Classical Meigs syndrome' management is surgical. After tumor removal, pleural effusion and ascites resolve.

Massive pleural empyema secondary to amoebic liver abscess in a child / Empiema pleural masivo secundario a absceso hepático amebiano en un niño

Abstract Background: Pleural empyema secondary to a ruptured amoebic liver abscess is a rare complication in the pediatric population. Case report: We report the case of a 13-year-old male with right flank abdominal pain, productive cough with foul-smelling sputum, fever, and respiratory distress. Physical examination revealed breathlessness, decreased vesicular murmur in the right hemithorax, abdominal distension, hepatomegaly, and lower limb edema. Laboratory tests revealed mild anemia, leukocytosis without eosinophilia, elevated alkaline phosphatase, hypoalbuminemia, and positive immunoglobulin G antibodies against Entamoeba histolytica in pleural fluid. He required a chest tube and treatment with metronidazole. After 2 months of follow-up, the abscesses disappeared, and the empyema decreased. Conclusions: Massive pleural empyema secondary to a ruptured liver abscess is a rare complication. The epidemiological link associated with the symptoms and serological tests can help in the diagnosis.

Al examen físico se encontró amplexación y murmullo vesicular disminuido en hemitórax derecho, distensión abdominal, hepatomegalia y edema de miembros inferiores. Los resultados del laboratorio evidenciaron anemia leve, leucocitosis sin eosinofilia, elevación de fosfatasa alcalina, hipoalbuminemia y anticuerpos IgG contra Entamoeba histolytica positivo en líquido pleural. Requirió tubo de drenaje torácico y tratamiento con metronidazol. A los dos meses de seguimiento los abscesos desaparecieron y el empiema disminuyó. Conclusiones: El empiema pleural masivo secundario a ruptura de absceso hepático es una complicación poco frecuente. El nexo epidemiológico asociado con la sintomatología y pruebas serológicas pueden ser de ayuda en el diagnóstico.

A comparative study of conventional cytology and cell block in the diagnosis of pleural effusion with special reference to immunohistochemistry

Background: Body cavity fluids are evaluated by cell block (CB) technique. In conventional cytological smears (CS), appropriate identification of the cells as either reactive mesothelial cells or malignant cells is a diagnostic problem. In CB method, there is increase in cellularity, so it gives more morphological details of cells and improving the sensitivity of diagnosis. Sections obtained by CB method are also can be stored for future study like immunohistochemistry (IHC). Aims and Objectives: The aim of the study was to determine the diagnostic efficacy of CB technique over conventional CS and to study of IHC in CB of malignant pleural effusion. Materials and Methods: This will be institution-based, cross-sectional, and observational study. The pleural fluid (except blood and pus) obtained by thoracocentesis from both male and female patient (>18 years of age) 100 cases was included in the study. Pleural fluid mixed with blood/pus, fluid from cystic lesion, and inadequate sample (<15 ml vol.) were excluded in the study. Results: Association between architectural pattern in CB versus architectural pattern in cytology smear showed statistically significant value Chi-square: 201.7417, P < 0.0001. Conclusion: We may conclude that CB technique is better than conventional cytology smear technique especially in case of malignant pleural effusion. It increases true positive cases and decreases false negative cases. It also increases cellularity, maintain architectural pattern, and cellular morphology.

Infección del miocardio por Mycobacterium tuberculosis: una localización infrecuente de una infección antigua

La tuberculosis miocárdica es una localización infrecuente que, en general, se caracteriza por cuadros clínicos silentes. Su diagnóstico se basa en la alta sospecha clínica y hallazgos inespecíficos en las imágenes cardíacas, pero la histopatología continúa siendo el estándar de oro para establecer el diagnóstico. La terapia antituberculosa ha sido exitosa, presentando mejoría radiológica y clínica en la mayoría de los casos. Presentamos el caso de una infección miocárdica por Mycobacterium tuberculosis en un hombre de 34 años que consultó por un cuadro de disnea de varias semanas de evolución. Se pesquisó un derrame pleural derecho y pericárdico grave, sin signos de taponamiento cardíaco. La RPC para M. tuberculosis en líquido pleural resultó positiva. El estudio histológico de pericardio y miocardio evidenció una pericarditis crónica y una inflamación granulomatosa, no necrosante, con células gigantes multinucleadas en el tejido miocárdico. Se estableció el diagnóstico de tuberculosis pleural, pericárdica y miocárdica y se inició tratamiento antituberculoso, presentando una mejoría clínica significativa.

Myocardial tuberculosis is a rare location that is generally characterized by silent clinical pictures. Diagnosis is based on high clinical suspicion and some nonspecific findings on cardiac imaging, but histological findings remain the gold standard. Treatment with standard antitubercular drugs llave been successful, presenting radiological and clinical improvement in most cases. We report a case of myocardial infection by Mycobacterium tuberculosis in a 34-year-old man, who presented with several weeks of dyspnea and evidence of right pleural effusion and severe pericardial effusion, without signs of cardiac tamponade. PCR for M. tuberculosis was positive in pleural fluid. The histologic study of pericardium and myocardium showed myocardial fibers with non-necrotizing granulomatous inflammation with multinucleated giant cells. Due to all the above, a diagnosis of pleural and myocardial tuberculosis was made, and tuberculosis treatment was started with significant clinical improvement.

Uma rara apresentação de plexopatia braquial por empiema de necessidade / A rare presentation of brachial plexopathy due to need empyema

Contexto: O empiema tem aumentado sua incidência ao longo das últimas décadas e ainda é a complicação mais comum de pneumonias. Apesar dos avanços no tratamento clínico, o acometimento do tecido pleural por infecções pode levar a sequelas irreparáveis e ainda apresenta uma alta mortalidade. Descrição do caso: Paciente do sexo masculino, 55 anos de idade, relatou queixa de dor em hemitórax e ombro esquerdos e parestesia difusa em membro ipsilateral há três dias. Tomografia de tórax revelou empiema pleural em lobo superior esquerdo e eletroneuromiografia evidenciou plexopatia braquial. Foi feita a punção guiada do empiema que demonstrou infecção por Staphylococcus aureus sensível à meticilina. Após drenagem do abscesso e antibioticoterapia, o paciente apresentou melhora progressiva dos sintomas. Discussão: O empiema de necessidade raramente se apresenta secundário a uma infecção bacteriana aguda, sendo geralmente causado por longas efusões pneumônicas tuberculosas. Sua manifestação clínica mais comum é a presença de massa dolorosa na região anterior do tórax, com exames de imagem mostrando alterações inflamatórias. A terapêutica preconizada se constitui de drenagem e antibioticoterapia. Conclusão: O diagnóstico de empiema de necessidade foi poucas vezes descrito na literatura e deve ser suspeitado em quadros infecciosos pulmonares com repercussão neurológica em plexo braquial.

Non-traumatic esophageal perforation: A case report on Boerhaave’s syndrome

Boerhaave’s syndrome is a potentially fatal condition characterized by spontaneous perforation of a previously healthy esophagus, due to severe vomiting or straining. It often presents with non-specific symptoms such as fever, pain, and vomiting and hence may go undiagnosed. The Makler’s triad, consisting of vomiting, chest pain, and subcutaneous emphysema, may be seen in only 50% of cases. Delayed diagnosis may result in complications such as sepsis, mediastinitis, pneumothorax, and multi-organ dysfunction. In general, patients presenting later than 48 h are conservatively managed with esophageal stenting. Surgical repair is usually reserved for those patients who present within 24 h, or are managed conservatively and develop complications. Mortality rises from 0% if treated within 24 h to about 29% if delayed more than 48 h. We present a case of Boerhaave’s syndrome in a 35-year-old male who presented with spontaneous respiratory distress and hemodynamic instability, about 36 h after the onset of vigorous vomiting. The case was managed initially with endoscopic insertion of a self-expanding metallic stent, followed later by surgical closure of the esophageal perforation. The patient, however, developed post-operative septic complications and died after a week

A rare case of tuberculous polyserositis � A case report

Polyserositis is defined as chronic inflammation of several serous membranes with effusions in serous cavities like Pericardial, Pleural and Peritoneal membranes, resulting in fibrous thickening of the serous membranes and sometimes constrictive pericarditis. There are various causes of polyserositis which include autoimmune diseases, neoplasia, endocrine diseases, drug � related causes and infectious diseases such as tuberculosis. Polyserositis in disseminated TB is a very rare presentation. Diagnosis is often delayed due to the non-specific presentation like polyserositis and its unusual nature. We herewith report a rare case of TB polyserositis, involving pleura, pericardium and peritoneum.

Empiema pleural por Parvimonas micra en un paciente inmunocompetente: reporte de un caso / Pleural empyema by Parvimonas micra in an immunocompetent patient: a case report

Se presenta el caso de un paciente joven inmunocompetente, con antecedente de tuberculosis pulmonar, que acude al hospital por un cuadro clínico subagudo de fiebre persistente, baja de peso, disnea y abolición del murmullo vesicular. La tomografía de tórax mostró un extenso empiema en hemitórax izquierdo. Se le toman muestras para detección de gérmenes comunes y se le colocan un tubo de drenaje torácico y se inicia antibioticoterapia. La prueba de MALDI-TOF MS identificó a Parvimonas micra, una bacteria anaerobia, comensal de la flora oral, asociado a periodontitis severa, escasamente reportado en empiema pleural, especialmente, en personas inmunocompetentes. En la evaluación odontológica se realizó el diagnóstico de gingivitis y pericoronaritis de la tercera molar. El paciente evolucionó favorablemente. Se sugiere que, en casos de empiemas pleurales subagudos o crónicos, se debe considerar, además de las micobacterias, como agente etiológico al Parvimonas micra, y optar por exámenes como MALDI-TOF MS o secuenciamiento del 16S rRNA, colocación de tubo de tórax, cobertura antibiótica empírica y evaluación odontológica.

We present the case of a young immunocompetent patient, with a history of pulmonary tuberculosis, who attended the hospital with a subacute clinical picture of persistent fever, weight loss, dyspnea and abolition of vesicular murmur. Chest CT scan showed an extensive empyema in the left hemithorax. Samples were taken for detection of common germs. Then, a chest drainage tube was placed and antibiotic therapy started. The MALDI-TOF MS test identified Parvimonas micra, an anaerobic bacterium, commensal to the oral flora, associated with severe periodontitis, but rarely reported in cases of pleural empyema, especially in immunocompetent patients. Gingivitis and pericoronaritis of the third molar were diagnosed during oral evaluation. The patient progressed favorably. Parvimonas micra should be considered as a possible etiological agent in cases of subacute or chronic pleural empyema, in addition to mycobacteria. Tests such as MALDI-TOF MS or 16S rRNA sequencing, chest tube placement, empirical antibiotic coverage and an adequate oral evaluation should be considered in these cases.

Animal tissue samples and sodium hydrosulfide standard solution were added with 5 times of cold reaction solution, after low temperature vibration grinding, highspeed centrifugation, the supernatant was incubated in dark for 12 hours, the fluorescence intensity was measured by fluorescent microplate reader. Hydrogen sulfide concentration was calculated according to the standard curve. The LOD of this method was about 0. 6 |JLmol • L

Assessment of Rare Case on Patient with Filariasis-Associated Bilateral Pleural Effusion

@#Bilateral pleural effusion is fluid accumulation in both lungs of pleural spaces. The clinical manifestations of bilateral pleural effusion (chylothorax) caused by filariasis are so rare that they are often challenging to diagnose. This case study described a 21-year-old woman, domiciled in Sumatra, with complaints of shortness of breath and swollen legs. Radiological examination results found bilateral pleural effusion. Initially, it was suspected that the effusion was caused by tuberculosis, Systemic Lupus Erythematosus (SLE), and malignancy; however, treatments for these did not improve the patient’s condition. A Water Seal Drainage (WSD) was inserted and a chylous or chylothorax pleural effusion was obtained, and microfilaria was founded in the nocturnal blood examinations. Oxygen and nursing interventions were administered using lung expansion and postural drainage techniques, supported by education on effective coughing and deep breathing, along with the fulfillment of nutritional needs and dietary adjustments

Analysis of risk factors associated with acute Stanford type B aortic dissection complicated with pleural effusion and observation of the curative effect after intracavitary repair / 中华内科杂志

Objective:To investigate the risk factors of acute Stanford type B aortic dissection (TBAD) complicated with pleural effusion (PE) and the short-term and long-term outcomes of thoracic endovascular aortic repair (TEVAR).Methods:A case-control study. The clinical and imaging data of 1 083 patients with acute TBAD admitted to the General Hospital of Northern Theater Command from April 2002 to December 2020 were retrospectively analyzed, including 211 cases with pleural effusion and 872 cases without pleural effusion. The baseline analysis of the two groups of patients was performed. The risk factors associated with pleural effusion were analyzed by binary logistic regression, and the results were expressed as odds ratio ( OR) and 95% confidence interval ( CI). According to the quantity of pleural effusion, they were simultaneously divided into small pleural effusion group and medium large pleural effusion group, to compare the short-term and long-term effects of TEVAR patients with different amounts of pleural effusion. Results:The incidence of pericardial effusion (17.5% vs. 3.8%, P<0.001), anemia (21.3% vs. 12.5%, P=0.001), aortic spiral tear (49.8% vs. 37.8%, P=0.002), dissection tear over diaphragm (57.8% vs. 48.1%, P=0.011), serum creatinine [85 (69, 111) vs. 81 (67, 100) μmol/L, P=0.011] and white blood cell levels[(11.3±4.2)×10 9/L vs. (10.3±4.2)×10 9/L, P=0.002] in acute TBAD pleural effusion group were significantly higher than those in non-pleural effusion group, and the hemoglobin level was significantly lower than that in non-pleural effusion group [(128±20) vs. (133±17) g/L, P<0.05]. Logistic stepwise regression analysis showed that pericardial effusion ( OR=5.038,95% CI 2.962-8.568, P<0.001), anemia ( OR=2.047,95% CI 1.361-3.079, P=0.001), spiral tear ( OR=1.551,95% CI 1.030-2.336 , P=0.002) and elevated white blood cell ( OR=1.059,95% CI 1.011-1.102, P=0.005) were independent risk factors for TBAD complicated with pleural effusion. The incidences of all-cause death (4/19 vs. 1.5% vs. 0.9%, P<0.001), aortogenic death (4/19 vs. 0.7% vs. 0.7%, P<0.001) and aortic related adverse events (4/19 vs. 1.5% vs. 1.1%, P<0.001) in patients with large pleural effusion during TEVAR operation were significantly higher than those in patients with small pleural effusion and those without pleural effusion, and the differences were statistically significant. At 1 month follow-up after TEVAR, the incidence of all-cause death (4/16 vs. 3.3% vs. 1.6%, P<0.001), aortogenic death (4/16 vs. 0.8% vs.0.7%, P<0.001), aorta related adverse events (4/16 vs. 4.1% vs. 4.7%, P=0.013) and overall clinical adverse events (4/16 vs.9.8% vs. 6.7%, P=0.014) in the medium and large thoracic group were significantly higher than those in the small pleural effusion group and no pleural effusion group, and the differences were statistically significant. At 1 year follow-up after TEVAR, the incidence of all-cause death (4/15 vs. 4.9% vs. 3.9%, P=0.004), aortogenic death (4/15 vs.2.5% vs. 2.1%, P<0.001), aorta related adverse events (5/15 vs. 11.5% vs. 9.4%, P=0.012) and overall clinical adverse events (5/15 vs. 18.9% vs. 13.1%, P=0.029) in the medium and large thoracic group were significantly higher than those in the small pleural effusion group and no pleural effusion group, and the differences were statistically significant. Conclusions:Single center data showed that pericardial effusion, anemia, spiral tear and elevated white blood cell were independent risk factors for acute TBAD complicated with pleural effusion; the early (1 month) and long-term (1 year) rates of all-cause death, aortic mortality, aortic adverse events and overall clinical adverse events were significantly higher in TBAD patients with moderate pleural effusion after TEVAR, and moderate and large pleural effusion was an independent risk factor for near and long-term aortic related adverse events after TEVAR surgery.

Diagnostic value of lung ultrasound in diagnosing postoperative atelectasis, pleural effusion and pneumothorax in adult patients: a systematic review and meta-analysis / 中华麻醉学杂志

Objective:To systematically evaluate the diagnostic value of lung ultrasound (LUS) in diagnosing postoperative atelectasis, pleural effusion and pneumothorax in adult patients.Methods:PubMed, Embase, Cochrane Library, Web of Science, Wanfang Database, China Science and Technology Journal Database and China National Knowledge Infrastructure were searched for studies comparing the accuracy of LUS Chest radiograph (CXR) or computed tomography (CT) in the diagnosis of postoperative atelectasis, pleural effusion and pneumothorax, and the parameters were the sensitivity and specificity of LUS in diagnosing postoperative atelectasis, pleural effusion and pneumothorax, and the area under the receiver operating characteristic curve (AUC). Analysis was performed using MetaDiSc 1.4, Review Manager 5.4, and STATA 16.0 softewares. CXR and CT were used as standard imaging examination methods, and the combined sensitivity, specificity and AUC of LUS were calculated. Meta regression analysis was conducted on the types of surgeries, standard imaging examination methods (CXR, CT), CXR (CT)/LUS examination intervals (>3 h, ≤3 h), and time points of postoperative LUS examination.Results:Fifteen studies involving 1 585 patients were finally enrolled in the present study. The combined sensitivity of LUS in diagnosing postoperative atelectasis, pleural effusion and pneumothorax was 0.91 (95% confidence interval [ CI] 0.88-0.93), 0.75 (95% CI 0.71-0.78) and 0.53 (95% CI 0.48-0.58), respectively, and the combined specificity was 0.96 (95% CI 0.95-0.97), 0.82 (95% CI 0.81-0.84) and 0.94 (95% CI 0.93-0.95), respectively, and AUC was 0.936 8 ( SE=0.044 2), 0.839 7 ( SE=0.076 7) and 0.914 7 ( SE=0.030 9), respectively. Meta-regression analysis showed that the type of surgery was a source of heterogeneity affecting the diagnosis of pneumothorax by LUS ( P=0.001), and the standard imaging examination method was the source of heterogeneity affecting the diagnosis of pleural effusion by LUS ( P=0.023). Conclusions:Although LUS has a weak ability in detecting non-clinically related pneumothorax (≤3 cm) and a low overall sensitivity in diagnosing postoperative pneumothorax, the specificity is high in adult patients.

Analysis of clinical features of 36 children with necrotizing pneumonia / 中国小儿急救医学

Objective:To summarize the clinical features, diagnosis, treatment, and outcomes of necrotizing pneumonia(NP)in children, so as to improve the understanding of NP.Methods:Children with NP admitted to the Children′s Medical Center of Hunan Provincial People′s Hospital from December 2012 to June 2020 were selected and divided into respiratory support group(nine cases) and non-respiratory support group(27 cases) according to whether they received respiratory support; and they were also divided into pleural effusion group(28 cases) and non-pleural effusion group(eight cases) according to whether combined with pleural effusion.The clinical data of all children were collected, and the differences between different groups were compared.Results:There were thirty-six children with NP, included 14 boys and 22 girls, with a median age of 30(12, 49) months, and the disease duration was 34(25, 42)days.All children had cough, 34 cases had fever, and the fever peak was 39.5(39.1, 40.0) ℃.Laboratory tests(all peaks) showed that blood white blood cell count was 20.77(15.65, 28.35)×10 9/L, neutrophil count was 15.11(8.52, 20.65)×10 9/L, C-reactive protein(CRP) was 104.00(23.45, 146.50)mg/L, D-dimer was 5.12(1.88, 8.04)mg/L, and lactate dehydrogenase(LDH) was 347.95(284.68, 447.81)U/L.The detection rate of pathogens was 58.33%(21/36), and the most common was Staphylococcus aureus(28.57%, 6/21). Eight cases underwent surgical treatment, including five cases of thoracoscopic surgery and three cases of thoracotomy.All patients improved and were discharged from hospital.The differences in hospital stay, white blood cell count, CRP, procalcitonin and LDH levels between respiratory support group and non-respiratory support group were statistically significant, and the median age, white blood cell count, CRP, D-dimer and LDH between pleural effusion group and non-pleural effusion group were statistically significant(all P<0.05). Further multivariate Logistic regression analysis showed that LDH was a risk factor for NP children receiving respiratory support( P<0.05), the area under the ROC curve of LDH was 0.802, whose the cut-off value was 471.21 U/L.There were no statistically significant differences in the indexes between effusion group and non-pleural effusion group. Conclusion:Children with NP are prone to repeated high fever, high inflammatory markers, and a long course of disease.Staphylococcus aureus is the most common pathogen.Serum LDH≥471.21 U/L is an early independent predictor of respiratory support for NP.

Evaluation of the effect of Zhushui plaster application and nursing combined with Elemene injection on lung cancer patients with malignant pleural effusion / 中国实用护理杂志

Objective:To study the effect of Zhushui plaster application and nursing combined with elemene injection on the psychological state, the degree of cancer-related fatigue, and the quality of life of lung cancer patients with malignant pleural effusion.Methods:According to the clinical controlled trial, a total of 100 patients with malignant pleural effusion of lung cancer admitted to the Department of Cardiothoracic Surgery Ⅱ and Vascular Surgery of Ningbo Medical Center Lihuili Hospital from April 2019 to December 2021 were convenient selected and divided into control group and experimental group with 50 cases in each group by random number table method. The control group received intrapleural perfusion therapy with elemene injection, and the experimental group was treated with Zhushui plaster on the basis of the control group. The psychological state, cancer-induced fatigue and quality of life of the two groups before and after treatment were compared.Results:There was no significant difference in baseline data between the two groups before intervention (all P>0.05). There were no significant differences in psychological status, cancer-induced fatigue and the quality of life before intervention between the two groups (all P>0.05). After the intervention, the anxious and depressed scores of the patients in the experimental group were (64.12 ± 3.24) and (60.38 ± 3.00), respectively, which were lower than those in the control group, (66.00 ± 3.69) and (62.10 ± 3.30), and the differences were statistically significant ( t=2.72, 2.73, both P<0.05). The scores of perceived fatigue, emotional fatigue, cognitive fatigue and behavioral fatigue in the experimental group were (5.66 ± 0.59), (5.26 ± 0.75), (4.00 ± 0.93) and (5.08 ± 0.80), respectively, which were lower than those in the control group, (5.98 ± 0.74), (5.70 ± 1.09), (4.42 ± 1.07) and (5.52 ± 1.00), respectively, and the differences were statistically significant ( t values were 2.10-2.46, all P<0.05); in addition, the dimensions and total scores of the quality of life in the experimental group were (50.54 ± 5.09), (52.49 ± 4.46), (50.40 ± 4.40), (48.96 ± 3.32) and (202.38 ± 15.42), respectively, which were higher than those in the control group, (47.82 ± 6.69), (49.40 ± 6.28), (47.24 ± 4.70), (46.56 ± 4.13) and (191.00 ± 15.79) respectively, and the differences were statistically significant ( t values were -3.65--2.29, all P<0.05). Conclusions:Zhushui plaster application and nursing combined with elemene injection can not only effectively control the negative psychological state of lung cancer patients with malignant pleural effusion and reduce the degree of cancer-related fatigue, but also improve their quality of life.

Value of cell paraffin block immunohistochemistry and pleural effusion CRKL and MIC-1 in the diagnosis of malignant pleural effusion / 国际肿瘤学杂志

Objective:To study the value of cell paraffin block immunohistochemistry and pleural fluid Crk like protein (CRKL) and macrophage inhibitory cytokine-1 (MIC-1) in the diagnosis of malignant pleural effusion.Methods:A total of 98 patients with pleural effusion treated in Shantou Central Hospital from February 2020 to February 2021 were retrospectively selected as the research objects, including 58 benign cases and 40 malignant cases. The levels of CRKL and MIC-1 in pleural effusion were detected by enzyme-linked immunosorbent assay. The pleural effusion was analyzed by cell paraffin block immunohistochemistry. The levels of various indexes in benign group and malignant group were compared. The diagnostic value of cell paraffin block immunohistochemistry and pleural effusion CRKL and MIC-1 for benign and malignant pleural effusion was analyzed by receiver operating characteristic (ROC) curve.Results:With pathological results as the gold standard, 54 cases of benign and 44 cases of malignant were diagnosed by cell paraffin block immunohistochemistry. The diagnostic accuracy was 75.5% (74/98) , and the sensitivity and specificity were 75.0% (30/40) and 75.9% (44/58) respectively. The levels of pleural effusion CRKL [2.84 (2.17, 3.98) ng/ml vs. 1.88 (0.94, 2.62) ng/ml], MIC-1 [2.28 (1.67, 2.98) ng/ml vs. 1.76 (1.22, 2.32) ] ng/ml] in the malignant group were higher than those in the benign group, with statistically significant differences ( Z=-4.57, P<0.001; Z=-3.09, P<0.001) . The optimal critical value of CRKL in pleural effusion for the diagnosis of malignant pleural effusion was 2.33 ng/ml, the area under the curve (AUC) was 0.76 (95% CI: 0.66-0.85) , and the sensitivity and specificity were 67.5% (27 /40) , 74.1% (43/58) . The optimal critical value of MIC-1 in pleural effusion for the diagnosis of malignant pleural effusion was 2.10 ng/ml, the AUC was 0.74 (95% CI: 0.64-0.85) , and the sensitivity and specificity were 60.0% (24/40) , 82.8% (48/58) . The AUC of MIC-1 and CRKL in pleural effusion combined with cell paraffin block immunohistochemistry for the diagnosis of malignant pleural effusion was 0.83 (95% CI: 0.75-0.91) , and the sensitivity and specificity were 85.0% (34/40) and 70.7% (41/58) . The sensitivity and AUC of combined diagnosis were significantly higher than those of CRKL and MIC-1 alone (sensitivity: χ2=4.26, P=0.046; χ2=6.27, P=0.012; AUC: Z=3.53, P<0.001; Z=4.14, P<0.001) . Conclusion:CRKL and MIC-1 in pleural effusion of patients with malignant pleural effusion are highly expressed, which can be used as indicators for the diagnosis of malignant pleural effusion. Detection combined with cell paraffin block immunohistochemistry can improve the diagnostic value of malignant pleural effusion.
