BACKGROUND
Hyperthyroid cats commonly have systemic hypertension, with a reported prevalence of 7% to 48%. Although hypertension might be expected to resolve once treatment restores euthyroidism, it can persist or only first develop after treatment.
OBJECTIVES
To determine the proportion of hyperthyroid cats with hypertension (systolic blood pressure [SBP] ≥160 mm Hg), persistence or first development of hypertension after successful radioiodine treatment, and correlation of post-treatment hypertension with azotemia or hypothyroidism.
ANIMALS
Four hundred one hyperthyroid nonazotemic cats were included in the study.
METHODS
Prospective, cross-sectional and before-and-after studies. All hyperthyroid cats had SBP measured by Doppler; 255 had SBP rechecked 6 months after successful radioiodine (I) treatment.
RESULTS
Of untreated hyperthyroid cats, 108/401 (27%) were hypertensive. A higher proportion of hypertensive cats were nervous/excited compared with normotensive cats (47% vs 12%; P < .001). Of the initially hypertensive cats, 87/108 cats were reexamined after I treatment; 43/87 (49%) cats normalized SBP, whereas 44/87 (51%) remained hypertensive. Of the initially normotensive cats, 16/168 (9.5%) first developed hypertension after successful I treatment. 7/60 (12%) of the I-treated hypertensive cats were azotemic and 9/60 (15%) were hypothyroid. A higher proportion of cats remaining hypertensive had nervous/excited demeanor than did normotensive cats (50% vs 17%; P < .001).
CONCLUSIONS/CLINICAL IMPORTANCE
Hypertension, when present, resolves in many hyperthyroid cats after successful treatment. Hyperthyroid cats uncommonly develop new hypertension after treatment. Persistent or newly detected hypertension was unrelated to azotemia or iatrogenic hypothyroidism. More frequently perceived nervousness/anxiety in radioiodine-treated hypertensive cats suggests that many of these cats might have "situational" hypertension, as hyperthyroid-induced hypertension should resolve after treatment.

Jejunal haemorrhage syndrome (JHS) is a sporadic and fatal enterotoxaemic disease in dairy cows associated with acute development and poor prognosis despite treatment. A 5-year-old Holstein cow with no reported pregnancy, three calving numbers, and 303 days in milk presented with hypothermia, discomfort, and inappetence. Anaemia, dehydration, faeces with blood clots, and absence of rumen and bowel movements were observed. We identified the presence of neutrophilia, hyperglycaemia, hypoproteinaemia, azotaemia, hyperlactatemia, hypocalcaemia, hypermagnesemia, hypokalaemia, and hypochloraemia through blood analyses. Necropsy and histopathologic examination revealed a dilated bluish-purple jejunum, blood clots within the jejunum, neutrophil infiltration into the submucosa of the jejunum, and vascular necrosis. Retrospective examination revealed extraordinary patterns of rumination time, activity, rumen mobility, and rumen temperature using biosensors and decreased milk yield. The abnormalities in the affected cow were detected before recognition by farm workers. To the best of our knowledge, this is the first report to examine data from biosensors in a cow with JHS. Our findings suggest that using biometric data may help understand the development of JHS.

A 6-year-old male domestic short-haired cat () was presented with weakness, anorexia, fever, icterus, a painful abdomen, ruffled hair and a tick infestation, and it had no prior surgery. Laboratory analysis revealed left-shifted neutrophils, thrombocytopenia, low albumin content and high serum bilirubin concentration as well as activities of hepatic enzymes including alanine aminotransferase and aspartate aminotransferase. Azotemia and increased serum levels of creatinine and urea were also recorded. In Giemsa-stained blood smear, gamonts were observed within neutrophils. Species-specific polymerase chain reaction assay was used to amplify an approximately 590 bp fragment of gene and confirmed infection. The cat was treated with imidocarb dipropionate and doxycycline and recovered completely. Six-month follow-up showed no recurrence. This study reveals the presence of in Iran and it should be considered in differential diagnosis in febrile and icteric cats. To the authors' knowledge, this is the first description of infection in a cat in Iran.

BACKGROUND AND AIM
Hematological and blood chemistry parameters are crucial for evaluating and monitoring canine multicentric lymphoma during chemotherapy. Pre-treatment hematological and blood chemistry parameters can be used as prognostic survival outcomes for this disease. Therefore, this study aimed to investigate the effect of hematological and blood chemistry parameters pre-treatment and 4 weeks post-treatment on the survival outcomes of dogs treated with either a combination of cyclophosphamide, vincristine, and prednisolone (COP) or a combination of COP with L-asparaginase (L-COP) protocols.
MATERIALS AND METHODS
We conducted a retrospective study. Medical records and hematological and blood chemistry parameters of 41 dogs with multicentric lymphoma treated with L-COP (n = 26) and the COP protocols (n = 15) were obtained from the hospital information system. Most cases were classified as high-grade lymphoma based on the Kiel cytological classification. The effects of hematological and blood chemistry parameters on survival outcomes were investigated using the Cox proportional hazard regression model. The median survival time (MST) for each hematological and blood chemistry parameter affecting survival outcome was established and compared using the Kaplan-Meier product limit method with the log-rank test.
RESULTS
Dogs with high-grade multicentric lymphoma that were treated with the COP protocol and had monocytosis at pre-treatment had a significantly shorter MST than dogs with normal monocyte counts (p = 0.033). In addition, dogs with azotemia, both pre-treatment and 4 weeks post-treatment, had a significantly shorter MST than dogs with normal serum creatinine levels (p = 0.012). Dogs with high-grade multicentric lymphoma treated with the L-COP protocol who had hypoalbuminemia (serum albumin concentration <2.5 mg/dL) at both pre-treatment and 4 weeks post-treatment had a significantly shorter MST than dogs with normal serum albumin levels (p < 0.001). Furthermore, dogs with leukocytosis at 4 weeks post-treatment had a significantly shorter MST than those with a normal total white blood cell count (p = 0.024).
CONCLUSION
Serum albumin level can serve as a simple negative prognostic indicator of survival outcomes in dogs with high-grade multicentric lymphoma treated with the L-COP protocol. Dogs with hypoalbuminemia pre-treatment and 4 weeks post-treatment tended to have a shorter MST than those with normal serum albumin concentrations.

Most cases of colorectal cancer develop from adenomatous polyps, slowly progressing within an average period of 8-10 years. McKittrick-Wheelock syndrome (MKWS) is a rare manifestation of tubulovillous adenoma. It generally presents as hypersecretory diarrhea with severe electrolyte and fluid depletion. Roughly, 5% of the published cases have reported malignant histopathology associated with MKWS, with little to no data regarding the malignant transformation process of those patients. Our patient was a 53-year-old Asian woman suffering from chronic secretory diarrhea, resulting in severe volume, electrolyte depletion, and prerenal azotemia, consistent for MKWS. Her symptoms initially improved with sulfasalazine but eventually worsened. She demonstrated signs of systemic (elevated leukocyte, CRP, and LDH) and local inflammation (dense lymphocyte infiltration in colorectal tissue) throughout the course of her disease. Serial pathological results showed rapid neoplastic progression of adenomatous polyp to adenocarcinoma within 1 year period. Surgical resection resulted in complete symptom resolution. Molecular examination showed a favorable profile of exon 4 Kirsten rat sarcoma viral oncogene homolog mutation, normal NRAS, BRAF, CDX2, and CK20 expressions. Her molecular pattern did not reflect the profile of an aggressive disease, suggesting the possibility of oncogenic processes outside the major pathways of adenoma to carcinoma progression. Chronic inflammation is a well-established risk factor for colorectal cancer, and prostaglandin E2 (PGE2) has been observed as one of the key regulators of tumor initiation and growth. PGE2 is also responsible for hypersecretory diarrhea associated with MKWS.

A 66-year-old non-smoker presented with a 2-week history of new-onset pedal oedema and gross haematuria. On evaluation, he was found to be hypertensive and oedematous with a haemoglobin of 19.1 g/dl, platelet count of 546,000/mm, and creatinine of 2.6 mg/dl. Urine examination revealed abundant RBCs with 3+ albumin on three separate occasions. His 24-h urine protein level was 3830 mg/day, with a serum cholesterol level of 303 mg/dl. Secondary erythrocytosis and thrombocytosis tests were negative. Bone marrow examination revealed hypercellularity, erythroid hyperplasia, tight clusters of large megakaryocytes, and megakaryocytic hyperplasia suggestive of polycythemia vera. PCR analysis revealed a JAK2V617 F (exon 14) mutation. In view of nephrotic syndrome, azotemia, and microscopic haematuria, a renal biopsy was performed, which revealed features of IgA nephropathy with advanced interstitial fibrosis and tubular atrophy. He was started on angiotensin receptor blockers with hydroxy urea as a part of treatment. This case report highlights the association of glomerular disease with polycythaemia vera and the need of prompt renal biopsy for diagnosis and management.

BACKGROUND
Emergency colorectal resections hold a significant position in general surgical practice, and pathologies of the left colon are relatively common. This study was conducted to assess the outcomes of isolated left colon surgeries with benign etiologies, drawing on clinicopathological and biochemical data.
METHODS
We carried out a retrospective review and statistical analysis of demographic, clinical, and laboratory data of patients who underwent left colon surgery at the general surgery clinic of a tertiary care hospital, excluding those with malignancy-related emergencies, from January 2017 to January 2022.
RESULTS
The average age of the 48 patients in the study was 56.9±16.4 years. Complicated acute diverticulitis was the most frequent indication for emergency surgery (n=19, 39.6%). The Hartmann procedure was the surgical technique most often employed (n=30, 62.5%). The rates of postoperative morbidity and mortality within 30 days were 27.1% and 8.3%, respectively. Increased postoperative morbidity was linked to advanced age (mean 65.4±15.8 vs. 53.8±15.7, p=0.028), the preoperative administration of vasopressors, lower platelet counts, hypoalbuminemia (<3 mg/dl), and azotemia (blood urea nitrogen >20 mg/dl). There was no statistically significant correlation between comorbidities, American Society of Anesthesiologists (ASA) scores, surgical methods, or other clinical data and postoperative outcomes.
CONCLUSION
For emergency colorectal surgery pertaining to left colon pathologies, it is critical to conduct a comprehensive evaluation in the perioperative period, especially for elderly and hypotensive patients with renal function abnormalities and for those requiring vasopressors.

This report describes for the first time, the antemortem diagnosis of hydatidosis in dromedary camel based on the WHO informal working groups on echinococcosis guidelines of echinococcosis classification. The case was admitted at the University Veterinary Hospital, Qassim University, Saudi Arabia, with a history of progressive weight loss and decreased appetite for the past 4 months. Alterations in hematobiochemical parameters included leukopenia, neutropenia, decreased hematocrit percent, red blood cells count and hemoglobin concentration, hypoproteinemia, hypoalbuminemia, hyperglobulinemia, hyperglycemia and azotemia. Ultrasonographically, multiple cysts were imaged within the hepatic tissue containing anechoic fluid and fibrin tags. Ultrasound-guided aspiration of a cyst revealed a clear non-turbid fluid. Ultrasonographic diagnostic is recommended for the work-up of cystic lesions of camel liver suspected to be due to Echinococcus granulosus.
