The diagnosis of human hydatidosis is primarily made using radiological and serological methods. Radiological methods are generally of low specificity and serological methods lack sensitivity, especially for pulmonary disease. In this study the capabilities of a new rapid test, the hydatid antigen dot immunobinding assay (HA-DIA), which was developed for the diagnosis of pulmonary hydatidosis, were studied and compared with another immunodiagnostic method, indirect hemagglutination (IHA). The study subjects included 18 patients, 9 women, 9 men; range 7 to 63 years; mean 30 years, with surgically proven pulmonary hydatidosis, a control group comprised of 14 patients; viral respiratory infections (1), cirrhosis (2), connective tissue disease (2), taeniasis (3), and 6 healthy donors. We found that the HA-DIA test had a sensitivity of $67\%$ and specificity of $100\%$, and that the IHA test had a sensitivity of $50\%$ and specificity of $100\%$. We conclude that HA-DIA is a simple, rapid, low cost assay that does not require instrumentation and has a higher sensitivity than IHA for the diagnosis of pulmonary hydatidosis.

Wegener써 육아종증은 1939년 Wegener가 \circled1 상하호흡기의 혈관염 및 괴사성 육아종, \circled2 전신적인 혈관염, \circled3 국한된 괴사성 사구체신염을 특징으로하는 질병을 Rhinogenic Granulomatosis라고 명명한데서 유래되었다. 초기에 이 질환은 몇달내에 사망하는 것으로 알고 있다. 그러나 최근 이 질환의 한정된 형(limited form)은 전형적인 형(classic form)에 비해 일반적으로 양성인 경과를 한다고 인지 되였다. 병리학적으로 이 질환은 한번의 조직생검으로 진단하기 힘들며 간혹 부검에서 확진되는 경우도 많다고 한다. 본교실에서는 최근 심한 시력장애, 청력장애를 일으킨 Wegener씨 육아종증 1례를 경험하였기에 이에 문헌고찰과 더불어 보고하는 바이다.

Background: Lung cancer is the most lethal type of cancer in the world. Several benign lung diseases may mimic lung carcinoma in its clinical and radiological presentation, which makes the differential diagnosis for granulomatous diseases more relevant in endemic regions like Brazil. This study was designed to describe the prevalence and the diagnostic work-up of benign diseases that mimic primary lung cancer in patients hospitalized at a university hospital from south of Brazil. Methods: This was a transversal study, which evaluated the medical records of 1,056 patients hospitalized for lung cancer treatment from September 2003 to September 2013 at University Hospital of Santa Maria. Results: Eight hundred and four patients underwent invasive procedures for suspected primary lung carcinoma. Primary lung cancer was confirmed in 77.4% of the patients. Benign disease was confirmed in 8% of all patients. Tuberculosis (n=14) and paracoccidioidomycosis (n=9) were the most frequent infectious diseases. The diagnosis of benign diseases was obtained by flexible bronchoscopy in 55.6% of the cases and by thoracotomy in 33.4%. Conclusion: Infectious diseases are the most frequent benign diseases mimicking lung cancer at their initial presentation. Many of these cases could be diagnosed by minimally invasive procedures such as flexible bronchoscopy. Benign diseases should be included in the differential diagnosis during the investigation for primary lung cancer in order to avoid higher cost procedures and mortality.

Background: Interleukin-33 (IL-33) has recently been implicated in tumor immunity. The aim of this study was to explore the clinical role of serum IL-33 in patients with non-small-cell lung cancer (NSCLC). Methods: Sera collected from 250 healthy volunteers (HV), 256 patients with benign lung diseases (BLD) and 262 NSCLC cases were subjected to IL-33 ELISA and relationships between serum IL-33 and clinical characteristics were evaluated. Results: Circulating IL-33 levels were higher in the NSCLC group in comparison with the HV and BLD groups (p<0.001). Using a cut-off level 68 pg/ml (95% specificity in the HV group), IL-33 showed a good diagnostic performance for NSCLC. Multivariate survival analysis indicated that serum IL-33 was an independent prognostic factor in the entire NSCLC group [hazards ratio (HR) = 0.64 for low versus high IL-33 levels, 95% confidence interval (CI) 0.50-0.82; p<0.001] and in 165 selected patients with locally advanced or metastatic disease receiving chemoradiotherapy or chemotherapy (HR 0.70, 95% CI 0.52-0.94; p=0.013). Conclusions: IL-33 is a promising potential diagnostic and prognostic marker in NSCLC, independent of the therapeutic intervention.

Congenital diaphragmatic hernia remains a disease with high neonatal mortality rate despite recent advance in neonatal intensive care. We experienced one case of the congenital diaphragmatic hernia with acute respiratory distress and left pulmonary hypoplasia in the neonate. The simple closure was performed through left paramedian approach after diagnosis. The postoperative course was uneventful except wound disruption. The patient was follow-up with good general condition.

콕시디오이데스 진균증은 미국 남서부 지역의 풍토병으로 알려져 있고 국내 발병 례가 적으므로 진단에 혼선 및 지연을 초래할 수 있다. 그러나 최근 해외 여행자의 증가와 함께 외국 풍토병의 국내 발현이 증가하는 추세임로, 임상양상과 진단이 맞지 않는 경우 환자의 해외여행 경력이 진단에 중요한 실마리를 제공할 수 있으며 외국 풍토병올 염두에 두어야 할 것이다. 또한 의심이 되는 경우 적극적인 조직검사를 통한 진단과 치료가 필요하다.

Nemaline myopathy is a genetically heterogeneous neuromuscular disorder and one of the most common congenital myopathies. The clinical manifestations usually vary depending on the age of onset. Neonatal nemaline myopathy has the worst prognosis, primarily due to respiratory failure. Several genes associated with nemaline myopathy have been identified, including NEB, ACTA1, TPM3, TPM2, TNNT1, CFL2, KBTBD13, KLHL40, KLHL41, LMOD3, and KBTBD13. Here, we report a neonatal Korean female patient with nemaline myopathy carrying compound heterozygous mutations in the gene KLHL40 as revealed using next generation sequencing (NGS). The patient presented with postnatal cyanosis, respiratory failure, dysphagia, and hypotonia just after birth. To identify the genetic cause underlying the neonatal myopathy, NGS-based gene panel sequencing was performed. Compound heterozygous pathogenic variants were detected in KLHL40: c.[1405G>T];[1582G>A] (p. [Gly469cys];[Glu528Lys]). NGS allows quick and accurate diagnosis at a lower cost compared to traditional serial single gene sequencing, which is greatly advantageous in genetically heterogeneous disorders such as myopathies. Rapid diagnosis will facilitate efficient and timely genetic counseling, prediction of disease prognosis, and establishment of treatments.

Background: Bovine respiratory disease (BRD) is one of the leading causes of economic losses in the beef and dairy industry. Reliable antemortem tools for diagnosing BRD would improve the efficacy of treatment and reduce costs. Here we examined whether the relatively simple technique of thoracoscopy can support BRD diagnosis under field conditions. We also compared various equipment set-ups in order to optimize the safety and efficacy of the procedure. A total of 24 thoracoscopic procedures were performed in 17 calves diagnosed with BRD and in 2 healthy control calves. Rigid and flexible endoscopes and industrial videoscopes were tested using various insertion approaches. The suitability of the technique was assessed in terms of duration, volume of air extracted, visualization score, and image quality. Safety was assessed in terms of rectal temperature, body weight, breaths/min, presence of fibrinogen, pain score, recovery time, intraoperative complications and risk of laceration or threatening collapse. Results: Insertion of a flexible endoscope via a right, dorso-caudal approach at the $5^{th}$ intercostal space allowed complete examination of the right lung in 15 min, as well as identification of main lung lesions and adherences in calves with BRD, without compromising calf welfare. While the dorso-caudal approach was optimal, it was associated with substantial discomfort when rigid endoscopes were used, minimal complications or mortality due to thoracoscopy were observed up to 28 days after the procedure. Videoscopes were as safe and easy to use as endoscopes, but endoscopes provided better image quality. Conclusion: This study provides the first field evidence that thoracoscopy can be safe to explore BRD-diseased calves. These results justify a larger study to rigorously assess the diagnostic performance of the technique.
