Evaluation of serological lateral stream assays regarding serious acute respiratory system malady coronavirus-2.
Such results are required to fill the gaps in understanding the geographical distribution patterns of wildlife related vector-borne parasites in migratory birds as potential carriers, raptors with high vulnerability, and domestic birds as pet or with economic value.Rheumatoid arthritis (RA) is a common autoimmune disease most well-known for its inflammatory, destructive polyarthropathy. Extraarticular manifestations of the disease may involve the respiratory system, including interstitial lung disease, pleural disease, pulmonary vascular abnormalities, and airways disease. Smoking is highly prevalent in the RA population, and may even have a synergistic effect in disease development and progression. In the diagnosis of pulmonary disease, this presents a unique diagnostic and therapeutic challenge. We present a case of a woman in her 50s who presented for evaluation of dyspnea and was found to have obstructive lung disease. In addition to RA, she had a significant smoking history and also owned pet birds, making definitive diagnosis difficult. Ultimately, chest imaging was crucial in identifying RA-related lung disease as the root cause of her symptoms, leading to successful treatment and symptom management.Pulmonary Langerhans cell histiocytosis (PLCH) is a rare cystic lung disease. The natural history is often unpredictable making it difficult to diagnose. We report a 63-year-old male with dyspnoea, chronic cough and recurrent respiratory tract infections, who developed progressive multifocal cystic lesions on pulmonary nodule surveillance over 4 years. He was a heavy smoker with a history of multiple spontaneous pneumothoraces in his teens. Extensive investigations culminated in a thoracoscopic wedge resection, which identified histiocytic nodules staining positive for CD1a and thus confirming the diagnosis of PLCH. It is now apparent that PLCH was the likely cause of his pneumothoraces.A 65-year-old woman had a ground glass nodule, which was suspicious for lung cancer, in her right lung S6 by chest computed tomography. For diagnosis, video-assisted thoracoscopic surgery was performed, and the specimen showed a pathological pattern of lymphocytic interstitial pneumonia (LIP). Four years after surgery, new localized ground glass shadows gradually increased on the base of the lung. However, because she had no respiratory symptoms and had normal respiratory function, she was observed with no medication. Subsequently, no other underlying diseases associated with LIP developed. The ground glass nodule was the initial lesion of LIP.Pneumocystis pneumonia affects immunocompromised hosts. The typical imaging finding is bilateral diffuse ground glass opacities. Here we presented a case of Pneumocystis causing biopsy-confirmed cavitary lung lesions in a patient with a predominant B cell defect with common variable immune deficiency.Vanishing lung syndrome (VLS) is a rare condition characterized by giant emphysematous bullae. It is frequently misdiagnosed as pneumothorax. We describe a case of a 30-year-old male who presented with shortness of breath, reduced effort tolerance, and pleuritic chest pain for three months. He was initially diagnosed with bilateral pneumothorax based on clinical examination and chest radiograph findings. However, further imaging with a high resolution computed tomography (HRCT) of the thorax confirmed bilateral giant emphysematous bullae. Our patient subsequently underwent video-assisted thoracoscopic surgery (VATS) and bullectomy. In this report, we discuss the clinical presentations, radiological features, and the management of VLS. We also highlight the differentiating features of VLS from a pneumothorax.Empyema thoracis, defined as the accumulation of pus in the pleural space, is a rare entity in the neonatal period. There are very few cases described in the medical literature and there are still no treatment protocols in the management of empyema in neonates. In older infants and children, intrapleural fibrinolytics and surgery are often utilized since treatment of complicated parapneumonic effusions with chest tube and antibiotics alone often fail due to the viscous fluid and presence of loculations. Presented here is a case of a term neonate who exhibited symptoms of respiratory distress on the sixth day of life. Imaging modalities revealed massive left sided pleural effusion with loculations and mass effects. Pleural fluid was grossly pus and exudative in nature. Gram stain revealed gram-positive cocci but culture was negative. Empiric broad-spectrum antibiotics and chest tube drainage were utilized and patient was discharged after forty-seven days of hospital admission. In spite of prolonged hospital stay, patient survived with no complications. Therefore, nonoperative therapy could still be an option for neonates with loculated empyema. The key to success in treatment is immediate identification of effusion, prompt initiation of antibiotics, and early effective chest tube drainage.Non-traumatic lower back pain is a common complaint seen in all emergency department (ED) visits. For many individuals, episodes of back pain are self-limited, but rarely, back pain is a signal of serious medical illness. A 58-year-old male was admitted to our ED suffering from lower back pain with radiation to the lower legs. learn more Examination found bilateral lower limbs weakness with numbness and weak dorsalis pedis pulse. This is the point which peripheral arterial disease was considered and contrast computed tomography scan of abdomen and pelvis was arranged. Enormous aortic bifurcation clots were seen. This patient was soon to recover from the illness after receiving transfemoral catheterization thrombolysis and stenting. Aortic saddle embolism is a rare case of spontaneous acute aortic occlusion which the embolus terminated and straddled at the aortic bifurcation, producing bilateral lower extremity arterial obstruction and led to serious hemodynamic and metabolic consequences. The objective in this report is to raise awareness about this potentially fatal condition. In addition, to emphasize the importance of a thorough assessment and expeditious treatment in order to prevent serious complications including limb loss and potential mortality.
