ABSTRACT
Cases of canine tuberculosis, a zoonotic infection of significant public health significance, are typically only sporadically reported in the literature. For this observational study, case details were collated both retrospectively and prospectively for dogs infected with Mycobacterium tuberculosis-complex (MTBC) organisms. A total of 18 previously unreported cases as well as 565 historically reported confirmed cases were reviewed. A variety of diagnostic techniques were used to make a confirmed diagnosis of tuberculosis (culture, interferon-gamma release assay [IGRA], and PCR). The reference standard for diagnosis is culture; however, this was negative or not attempted in some dogs. Where fully speciated, all cases were caused by infection with one of three MTBC organisms: M. tuberculosis, Mycobacterium bovis, or Mycobacterium microti. This study includes the first documented canine infections with M. microti in the UK. All cases were assigned to one of four clinical groups based on the presenting signs: 44.1% were primarily pulmonary, 14.5% were primarily abdominal, and the remainder were disseminated or miscellaneous. The development of adjunctive tests remains necessary to support early treatment decisions pending reporting of culture for MTBC organisms, which can take weeks to months. Definitive treatment, where attempted, was successful in most cases. Of the 13 dogs treated by the authors with triple combination antimicrobial therapy, a good clinical outcome was seen in 12 (92%) of them.

OBJECTIVE: To compare 2 point-of-care lung ultrasound (LUS) protocols for quantification of B-lines in cats without evidence of respiratory disease based on history, physical examination, and thoracic radiography. DESIGN: Prospective observational study. SETTING: Single center, veterinary teaching hospital. ANIMALS: Fifty-seven cats without respiratory disease based on history, physical examination, and thoracic radiographs. INTERVENTIONS: All cats had 2 point-of-care LUS protocols performed bilaterally: a regional protocol (veterinary bedside lung ultrasound evaluation [VetBLUE]) and a more comprehensive vertical sweeping (VS) protocol. The total number of B-lines per cat, number of sites with B-lines, and maximal number of B-lines at each site were recorded and compared. MEASUREMENTS AND MAIN RESULTS: Ten cats (18%) had at least 1 B-line identified with VetBLUE, versus 29 (51%) with VS. Comparing protocols, VS had a statistically higher total number of B-lines per cat, higher number of sites with B-lines, and higher maximal number of B-lines per site. B-lines that were too numerous to count were identified at a single location in 1 cat with VetBLUE and 2 cats with VS. A maximum of 3 B-lines were identified at all other positive sites regardless of the protocol used. On average, it took 1.79 times longer to complete VS bilaterally compared to VetBLUE (median [interquartile range]: 140 [33] and 78 [14] s, respectively) (P = 0.001). CONCLUSIONS: This study demonstrates it is not uncommon to identify a single or even multiple B-lines in 1 or several sites on LUS in cats deemed to be clinically free of respiratory pathology-essential knowledge when using LUS as a screening test and to monitor intrathoracic lesions. In cats asymptomatic for respiratory disease, VS generally identifies more B-lines than VetBLUE, likely because it assesses a larger lung surface area. The sonographic identification of B-lines should be interpreted considering the LUS protocol used, history, and other diagnostics to determine their clinical significance.

SUMMARY OBJECTIVE: To demonstrate the need of performing esophageal pH monitoring and manometry in patients with clinical suspicion of Gastroesophageal reflux disease, as more accurate and practical complementary exams in the indication of surgical treatment. METHODS: A systematic review was carried out in the PubMed/Medline database, based on the recommendations of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, selecting studies in humans, published in Portuguese, Spanish, and English, from January 1, 2009 to August 5, 2020. The following descriptors were used: "reflux gastroesophageal" AND "surgery" AND "surgical treatment" AND "esophageal manometry" OR "pH monitoring". After that, retrospective or prospective observational studies with a sample of less than 100 individuals, or with limited access, reports or case series, review articles, letters, comments, or book chapters were excluded. To facilitate the application of the exclusion criteria, the Rayyan management base was used. RESULTS: Out of the 676 studies found, 19 valid and eligible studies were selected to make inferences. CONCLUSIONS: Based on the best evidence, currently, considering national particularities, performing a 24-hour esophageal pH monitoring and esophageal manometry for all patients undergoing anti-reflux surgery.
