COVID-19, Chronic Obstructive Pulmonary Disease and Pneumothorax: A Frightening Triad

We describe the case of a male patient admitted to our emergency department during the Italian COVID-19 epidemic, for progressive worsening dyspnoea. A diagnosis of pneumothorax and diffuse interstitial lung involvement was promptly made by lung ultrasound and confirmed by an HRCT scan. A chest CT scan also showed diffuse emphysema, as observed in chronic obstructive pulmonary disease (COPD), and small consolidations in the lower lobes, suggestive for COVID-19 pneumonia. A chest tube was immediately inserted in the emergency room with complete resolution of the dyspnoea. A nasopharyngeal swab for 2019-nCoV was positive. Unfortunately, the patient died from COVID-19-related acute respiratory distress syndrome after 48 days of hospitalization.

Primary neuroendocrine tumor in a canine

The objective know the cause of death of the pet. Pulmonary neoplasms can arise from all parts of the lung, with a histological pattern. Tumors derived from the epithelium of the large airways are located near the lyle of the lung. The majority of canine tumors are adenocarcinomas and progressions from a bronchiole-alveolar pattern to one of mucus-secreting glands or papillary growth. This case was presented, at the University of Guadalajara Animal Pathology Research Center, Canberman cadaver, female, 10 years old and weighing 19 kg, the clinical history indicates that the animal had 12 days of bronchopneumonia; At necropsy he presented Lungs: Severe diffuse emphysema, moderate congestion, discrete diffuse thickening of the pleura and moderate edema, characteristic of the tumor, is classified as anaplasic small cell carcinoma fusiform type. Some lymph nodes have invasion of tumor cells of the lung. Small cell lung tumors are currently classified as neuroendocrine or carcinoid tumors. Their contribution sensitize animal owners so that they attend them on time, and have a better quality of life.

CRITERIA OF SURGICAL RISK IN PATIENTS WITH DIFFUSE LUNG EMPHYSEMA WITH LARGE AND GIANT BULLAS

The article presents an assessment of postoperative period in patients with diffuse lung emphysema with large and giant bullas on the basis of surgical risk criteria, which were developed for the patients with diffuse emphysema without bullas. Retrospective study determined the group of patients who had high rate of surgical complications after bullectomy. The patients (46) were divided into 2 groups and it depended on the initial condition of the patients. There was stated, that the main criterion of surgical risk was a decrease of the level of OFL lower than 20% of the proper level in patients with large and giant bullas.

ULTRASONIC ASSESSMENT OF DIAPHRAGM CONDITION OF THE PATIENTS, WHO PASSED THE SELECTION FOR LUNG VOLUME REDUCTION SURGERY

The article showed the results of ultrasonic assessment of topographic and functional diaphragm indices in patients with severe diffuse emphysema. They passed the selection for lung volume reduction surgery. The comparison of diaphragm indices was presented in patients with diffuse emphysema and control group of healthy volunteers. Dynamics of diaphragm condition was studied after surgical treatment. There wasn’t noted any statistical difference of diaphragm topographic indices as compared with the control group. There wasn’t shown a correlation between respiratory function indices and functional diaphragm indices, but it was noted a positive tendency in characteristics during quiet breathing.

Emphysematous abomasitis in a lamb by bacteria of the Sarcina genus in Southern Brazil

ABSTRACT: Abomasal bloat associated with Sarcina genus bacteria is a rare condition reported in young ruminants. An outbreak characterized by the sudden death of eight lambs from a total of 80 lambs (30 days-old) occurred on a property located in the city of Palmares do Sul in the state of Rio Grande do Sul. Deaths began to occur after the introduction of supplementation into the diet of lambs. At necropsy, the abomasum was distended by gas and had diffusely thickened walls and emphysema. On microscopic examination, the abomasum showed marked diffuse emphysema and multifocal areas of mild superficial necrosis with many coccoid structures measuring approximately 2µm in diameter, arranged in tetrads, compatible with Sarcina genus bacteria. After removing supplementation from the diet, no more deaths occurred. The diagnosis of this case was established by gross and microscopic lesions in addition to the clinical and epidemiological findings. Therefore, it was concluded that it was an outbreak of emphysematous abomasitis by Sarcina genus bacteria in lambs.
