This case report shows that Mycobacterium avium subsp. paratuberculosis (MAP) infection can cause clinical disease in domestic dogs, and should be considered as a differential diagnosis for gastrointestinal inflammatory conditions. A male dachshund presented with lethargy and pain. Enlarged mesenteric lymph nodes were found on abdominal ultrasound examination. Cytological examination of lymph node aspirates was consistent with granulomatous inflammation, which was culture-confirmed as MAP. Although we were unable to confirm the source of infection, the dog’s history included exposure to sheep in the Western Cape.

Post mortem surveillances, for the detection of tuberculous lesions in particular depend on the work load time and the diligence of the inspector conducting the examination. The first aim of the study was to determine the trend of occurrence of tuberculous lesions in two abattoirs in Addis Ababa and Debre-Zeit (Ethiopia). The second aim of the study was to determine prevalence of the tuberculin skin test results in 10 dairy farm areas in Addis Ababa. The third aim was to detect tuberculous lesions and causal agents from tissue samples of the respiratory tract and mesenteric lymph nodes of the slaughtered cattle. The ten year (1996–2005) retrospective analysis of the meat inspection of 2 455 289 slaughtered animals showed that 707 (0.028%) were found with tuberculous lesions in parenchymatous organs of which were 699 (0.052%) of 1 336 266 cattle, 4 (0.001%) of 534 436 sheep, 3 (0.001%) of 573 767 goats and 1 (0.009%) of 10 820 pigs. The tuberculous lesions found in cattle were statistically highly significant (P < 0.01) than in other animals. The bovine tuberculin skin tests were conducted in Addis Ababa in 10 farm areas in 85 dairy farms having 2 098 cattle. Positive reactions were obtained from 9 farm areas in 41 (48%) herds which included 392 (19%) of the animals. In a current study, tuberculous lesions were found in 34 (3.5%) animals by the meat inspection surveillance of 984 cattle. Histopathologically, granulomatous inflammation was evident in 3 (8.8%) animals with tuberculous lesions. A highly sensitive PCR (IS6110) was positive in 4 of 34 (11.8%) animals with tuberculous lesions and in 1 (2.9%) of animal without lesions. The analyzed data and these study findings indicated that tuberculosis in cattle is an existing problem inEthiopia which needs to be solved.

Abdominal Ultrasound Examination

Purpose: To describe a case of endoluminal graft exclusion of a proximal para-anastomotic pseudoaneurysm that occurred 17 years following aortobifemoral bypass for occlusive disease. Methods and Results: The lesion was found on abdominal ultrasound examination as part of a work-up for acute abdominal pain and upper gastrointestinal bleeding in a 67-year-old male. A 5-cm saccular pseudoaneurysm was confirmed by preintervention aortography and spiral computed tomography (CT) scanning. Because of the patient's acute symptoms and high-risk medical condition (cardiomyopathy), he was deemed a candidate for endoluminal bypass. At the time of intervention, intravascular ultrasound (IVUS) interrogation identified a 3.5-cm-long separation of the existing aortic graft from the proximal aortic stump with a large pseudoaneurysm. The lesion was isolated and repaired by placement of an aortic-to-right iliac endoluminal bypass, ligation of the left limb of the aortofemoral graft, and femorofemoral bypass to restore blood flow to the lower extremities. Spiral CT scans at 48 hours and 3 months following the procedure confirmed complete isolation of the lesion. Conclusions: This case illustrates the feasibility of endografting for repair of aortic para-anastomotic pseudoaneurysms, and it also highlights the potential role of IVUS imaging in endoluminal graft deployment.

A 6-y-old neutered male ferret ( Mustela putorius furo) was presented because of a 1-mo history of progressive weight loss, chronic cough, and hair loss. On clinical examination, the animal was coughing, slightly depressed, moderately hypothermic, and had bilateral epiphora. Thoracic radiography was suggestive of severe multinodular interstitial pneumonia. Abdominal ultrasound examination revealed hepatosplenomegaly and mesenteric and pancreaticoduodenal lymphadenopathy. Fine-needle aspiration of the pancreaticoduodenal lymph node, followed by routine Romanowsky and Ziehl–Neelsen stains, revealed numerous macrophages containing myriad acid-fast bacilli, leading to identification of mycobacteriosis. Autopsy and histologic examination confirmed the presence of disseminated, poorly defined, acid-fast, bacilli-rich granulomas in the pancreaticoduodenal and mesenteric lymph nodes, intestines, and lungs. Destaining of May-Grünwald/Giemsa–stained slides with alcohol, and then restaining with Ziehl–Neelsen, revealed acid-fast rods and avoided repeat tissue sampling without affecting the Ziehl–Neelsen stain quality and cytologic features. Tissue samples were submitted for a PCR assay targeting the heat shock protein gene ( hsp65) and revealed 100% homology with Mycobacterium genavense. We emphasize the use of special stains and PCR for identification of this potential zoonotic agent.

Objectives Morphologic anomalies of the feline gallbladder (GB) have been previously reported in the literature. These morphologic variants are frequently encountered on routine abdominal ultrasound examination. The aim of this study was to provide an ultrasonographic classification system of these variants and document the overall incidence in the feline population. Methods A prospective, descriptive study was undertaken; cats that had an abdominal ultrasound examination that included at least one sagittal and transverse plane image of the GB were included. GB shape was evaluated and categorized based on a classification scheme of morphologic variants modified from the human literature. Septated (S), bilobed (B1, B2, B3), duplex (D) and complex (C) categories were described. Results Of 516 cats included in the study, 389 had normal GB morphology, while 127 had anomalous GB morphology. The overall incidence rate of anomalous GB morphology was 24.61%. When examined by morphologic type, the septated (S) morphology had an incidence of 9.69%. A bilobed (B) morphology was the most commonly observed classification; incidence was 14.35% within our population; incidence of B1, B2 and B3 subtypes were 2.91%, 6.98% and 4.46%, respectively. Duplex GBs only made up 0.39% of the total population. The incidence of complex (C) morphologies was 0.19%. Conclusions and relevance The incidence of GB morphologic anomalies was higher in our population than previously reported. Identification of these anomalies on routine ultrasound evaluation is common; numerous different morphologies can be identified and a standardized classification scheme is proposed. Complete evaluation of morphology can be challenging, particularly with regard to cystic duct anatomy. Clinical significance is uncertain and future studies are warranted to determine the relationship between morphologic variants and hepatobiliary disease.

Inflammatory Conditions

Polymyalgia rheumatica and temporal arteritis are distinct but overlapping inflammatory conditions of unknown aetiology. They almost exclusively affect people over 50 years of age, women more than men (ratio 2–3:1), and particularly those of Nordic heritage. Temporal arteritis is characterized by granulomatous inflammation that penetrates all layers of the wall of medium and (often) large muscular arteries, in particular the superficial temporal artery. Histological examination of tissues from patients with polymyalgia rheumatica shows nonspecific changes only. The term ‘giant cell arteritis’ is properly used only to describe patients with biopsy-proven arteritis....

Perivascular Inflammation

This case study describes the cytological and histopathological findings of cutaneous masses in a bovine, including a peripheral nerve sheath tumor (PNST), vaccine-associated granulomatous inflammation, and eosinophilic inflammation due to parasitosis. A six-year-old undefined cow (SRD) presented with heterogeneous cutaneous lesions including multiple nodules in the left paralumbar fossa, bilaterally at the withers, and scattered along the dorsum, limbs and near the tail; some lesions were associated with ticks. Cytology of these nodules showed benign mesenchymal neoplasia (paralumbar fossa), granulomatous and pyogranulomatous inflammation (withers) and keratin (dorsum). Histopathology, in this order, confirmed PNST, post-vaccination granuloma, and eosinophilic dermatitis. A peripheral nerve sheath tumor was suspected based on the histological findings, showing a well-delineated proliferation of fusiform cells arranged in plexiform structures, which appeared red by Masson's Trichrome stain. The diagnosis was confirmed by immunohistochemistry (anti-S100 antibody). Vaccine reaction often occurs in cattle, and cytological examination is sufficient to determine the inflammatory process. Eosinophilic dermatitis is usually accompanied by perivascular inflammation and reflects the exfoliative process by the oral apparatus of the parasite.

A 10 yr old domestic longhair presented with a 2.5 mo history of recurrent hematuria. Abdominal ultrasound examination demonstrated a thickened urinary bladder, abdominal lymphadenopathy, and a thickened and rounded spleen. Cytologic examination of fine-needle aspirate samples revealed Histoplasma capsulatum organisms in the urinary bladder wall and spleen. The cat was treated with itraconazole (10 mg/kg per os q 24 hr for 2.5 wk). The cat was euthanized after 19 days of treatment because of lack of improvement. To the authors’ knowledge, this is the first documented case of feline disseminated histoplasmosis diagnosed in the urinary bladder wall.

Abdominal Ultrasound Examination

This paper describes a prospective three-year study using abdominal ultrasound examination in 114 new CAPD patients. Gallbladder disease was common (22.8%) and four of 16 patients with gallstones (25%) required cholecystectomy after 1–14 (i 7.8 months) on CAPD. Two of these four had evidence of peritonitis in association with cholecystitis. Also we analyzed the clinical course of eight patients on chronic PD who underwent cholecystectomy. They had no serious morbidity, and all returned to chronic PD. While abdominal pain is one of the main features of CAPD-related peritonitis, other causes of abdominal pain may be more difficult to evaluate in the patient on peritoneal dialysis (PD); such causes potentially are more serious because they threaten the continuance of PD as a mode of therapy. Cholecystitis related to cholelithiasis is one such possible cause of abdominal pain. However, since ultrasonography can reliably and non-invasively detect the presence of gallstones, we have used it prospectively to screen patients entering our CAPD training program. This paper reports our findings and the subsequent course of those found to have gallstones during a three-year period. In addition we also reviewed the feasibility of cholecystectomy, its hazards and outcome in eight patients on chronic peritoneal dialysis who underwent this procedure at Toronto Western Hospital in the past seven years.
