AI Article Synopsis

  • The study assessed the prevalence and risk factors for urinary tract infections (UTI) in dogs post-surgery for thoracolumbar intervertebral disc (IVD) extrusions.
  • It found a 27% overall UTI prevalence, with variations at different time points after surgery (15% before, ranging up to 20% on the 7th day).
  • Key risk factors for UTI included female sex, inability to ambulate or urinate, lack of perioperative antibiotics, and low body temperature during anesthesia.

Article Abstract

Objective: To determine the prevalence of urinary tract infections (UTI), factors that correlate positively with UTI, and whether identified UTI are most likely community- or hospital acquired in dogs with surgically treated type 1 thoracolumbar intervertebral disc (IVD) extrusions.

Study Design: Prospective cross-sectional clinical study.

Sample Population: Dogs (n=92) that were surgically treated for a thoracolumbar extradural compressive spinal cord lesion that was consistent with type 1 IVD extrusion.

Methods: Dogs were evaluated for bacterial lower UTI when possible by cystocentesis and urine culture before surgery, and 48-72, 96-120 hours, and 7 days after surgery while hospitalized. Paraparesis, confirmation of thoracolumbar extruded nucleus pulposus, and informed owner consent were required for study inclusion. Urine specimens (n=297) were cultured and both objective and subjective clinical data were obtained.

Results: Prevalence of UTI in dogs with surgically treated type 1 thoracolumbar IVD extrusion was 27% (25 dogs). Temporal prevalence of UTI was 15% (13/89) before surgery, 12% (11/91) at 2-3 days, 16% (12/76) at 4-5 days, and 20% (8/41) at 7 days after surgery. Statistically significant factors affecting UTI prevalence included neurologic and urinary status, sex, administration of perioperative antibiotics, and amount of time body temperature was <35 degrees C during anesthesia.

Conclusion: UTI are common in dogs with surgically treated type 1 thoracolumbar IVD extrusion. Females, dogs that cannot ambulate or voluntarily urinate, dogs not administered perioperative cefazolin, and dogs whose body temperature falls <35 degrees C during anesthesia have a higher incidence of UTI.

Clinical Relevance: All dogs with surgically treated type 1 thoracolumbar IVD extrusion should be monitored for the presence of UTI; however, close attention should be paid to females and dogs that cannot ambulate or voluntarily urinate.

Laboratory of Veterinary Clinical Oncology, Joint Department of Veterinary Medicine, Faculty of Applied Biological Sciences, Gifu University, Gifu, Japan (T.M.).

Although intracranial and spinal cord meningioma prognoses have been reported, few studies have evaluated the outcomes and prognoses of orbital and optic nerve meningiomas in dogs. We aimed to evaluate the outcomes of canine orbital meningiomas. The seven dogs included were cytologically or histopathologically diagnosed with meningiomas.

Cervicofacial non-tuberculous mycobacterial infection should be a part of the differential diagnosis for immunocompetent children ages 1 to 5 years who present with painless submandibular or preauricular lymphadenopathy. Although a benign and self-limiting disease, patients can develop a chronically draining fistula if not diagnosed and treated promptly. The diagnostic process can be managed with a combination of microbiological studies, cytology, laboratory tests, and imaging studies.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) is the presence of somatic mutations in myeloid and lymphoid malignancy genes in the blood cells of individuals without a hematologic malignancy. Inflammation is hypothesized to be a key mediator in the progression of CHIP to hematologic malignancy and patients with CHIP have a high prevalence of inflammatory diseases. This study aimed to identify the prevalence and characteristics of CHIP in patients with inflammatory bowel disease (IBD).

Hormone replacement therapy for steatotic liver management after surgical menopause.

Clin J Gastroenterol

Department of Medicine, Division of Gastroenterology and Hepatology, Shinshu University School of Medicine, 3-1-1 Asahi, Matsumoto, Nagano, 390-8621, Japan.

Although steatotic liver onset after natural menopause has been reported, evidence on the clinical course and treatment options for steatotic liver after surgical menopause is scarce. A 34-year-old woman with a history of severe obesity presented to our department with liver dysfunction following total hysterectomy and bilateral oophorectomy. Her serum estradiol level was notably low at 22 pg/mL, and a liver biopsy revealed significant fatty degeneration, lobular inflammation, hepatocyte ballooning, and stage F1 fibrosis.
