Evaluation of noninvasive blood pressure in anesthetized horses: Bias, limits of agreement, and comparative detection of a predetermined mean blood pressure warranting treatment.

Oscillometric blood pressure monitoring may be a practical tool for short procedures or those performed outside of the operating room. Oscillometric and direct blood pressure values in 30 juvenile and adult horses in a clinical setting using mixed effect models were compared. The limits of agreement and percentage errors were also calculated. We evaluated the sensitivity and false positive rate for the oscillometric method to trigger an intervention for treating blood pressure [direct mean arterial pressure (MAP) < 70 mmHg]. Oscillometric MAP and diastolic arterial pressure (DAP) differed from direct values (P < 0.001); systolic arterial pressure (SAP) did not (P = 0.08). Wide limits of agreement were observed. Percentage errors were smaller for SAP (39%) than for MAP and DAP (48% and 72%). The oscillometric monitor indicated there was a requirement for blood pressure treatment with a true positive rate of 82%, consequently, it failed 18% of the times. The false positive rate (unnecessary treatment) was 55%.

Évaluation non invasive de la pression artérielle chez des chevaux anesthésiés: biais, limites d'accord et détection comparative d'une pression artérielle moyenne prédéterminée justifiant un traitement. La surveillance oscillométrique de la pression artérielle peut être un outil pratique pour les procédures courtes ou celles effectuées hors de la salle d'opération. Les valeurs oscillométriques et directes de la pression artérielle chez 30 chevaux juvéniles et adultes en milieu clinique ont été comparées à l'aide de modèles à effets mixtes. Les limites d'accord et les pourcentages d'erreurs furent également calculés. Nous avons évalué la sensibilité et le taux de faux positifs de la méthode oscillométrique pour déclencher une intervention pour le traitement de la pression artérielle [pression artérielle moyenne directe (PAM) < 70 mmHg]. La PAM oscillométrique et la pression artérielle diastolique (PAD) différaient des valeurs directes (P < 0,001); mais pas la pression artérielle systolique (PAS) (P = 0,08). De larges limites d'accord ont été observées. Les pourcentages d'erreurs étaient plus faibles pour PAS (39 %) que pour PAM et PAD (48 % et 72 %). Le moniteur oscillométrique a indiqué qu'il y avait une exigence pour un traitement de la pression artérielle avec un taux de vrais positifs de 82 %, par conséquent, il a échoué 18 % des fois. Le taux de faux positifs (traitement inutile) était de 55 %.(Traduit par Dr Serge Messier).

The elusive extremities: a case of extramammary Paget disease.

Extramammary Paget disease is a rare dermatological condition resembling Paget disease that occurs most commonly in the anogenital area and axilla. We present the case of an elderly male who had come with complaints of an itchy, erythematous and raised lesion in the perianal region for 3 months that did not respond to antifungals. A biopsy was taken from the lesion site and the diagnosis was confirmed by histopathological examination. It is important to be aware of conditions like extramammary Paget disease when an elderly individual presents with a non-specific pruritic lesion in the perianal area that is non-responsive to treatment; the diagnosis of which can be made only by doing a biopsy from the concerned site. This highlights the importance of histopathological examination in such ambiguous cases.

Uncovering the Unknown: Granulomatous Peritonitis After Right Ovarian Cystectomy at a Tertiary Care Center in South India-A Case Report.

Background. Granulomatous peritonitis is a rare postoperative complication caused by a delayed hypersensitivity reaction to foreign substances. It can be challenging to diagnose owing to its vague presentations, and its possibility is often overlooked. Tubercular peritonitis and peritoneal carcinomatosis are the 2 crucial differential diagnoses that need to be taken into account. However, making a clinical differentiation between these 2 entities is challenging and necessitates a careful histopathological and microbiological analysis. Case Presentation. In this report, we present the case of a 28-year-old female who developed granulomatous peritonitis following a right ovarian cystectomy. The diagnosis was confirmed by histopathological examination. Conclusion. We must be aware of this rare entity, which, if left untreated, could have serious consequences, and consider its possibility in cases where the patient complains of abdominal pain after any abdominal procedure. We hope to provide insights into the importance of histopathological examination in aiding a confirmatory diagnosis of this entity.

A needle in the haystack: An unusual case presentation of ganglioneuroblastoma at a tertiary care center in Coastal Karnataka.

Key Clinical Message: This case report highlights the importance of recognizing and accurately diagnosing ganglioneuroblastoma, an uncommon variant of neuroblastic tumors in children. Ganglioneuroblastomas have diverse clinical and morphological presentations, and histopathological examination is paramount in guiding treatment decisions, especially in cases with ambiguous symptoms. Early detection is crucial, as the prognosis varies significantly based on the subtype and the presence of metastatic disease. Clinicians should maintain a high index of suspicion and utilize radiological examinations to promptly identify and treat these tumors. Abstract: Children are frequently affected by neuroblastic tumors, which grow from the sympathoadrenal lineage of the neural crest during its development. However, intermixed ganglioneuroblastomas are far less common within the same tumor spectrum, the diagnosis of which could become challenging amidst an unusual presentation. In our case report, we present a 4-year-old boy who had complaints of fever and difficulty in walking, with a supra-renal mass on ultrasound, which was diagnosed as ganglioneuroblastoma-intermixed type on histopathological examination. This report aims to contribute to the understanding of the diverse clinical and morphological spectrum of ganglioneuroblastomas and the importance of multidisciplinary collaboration and histopathological examination to enhance decision-making in such ambiguous scenarios.

Hypophosphatemia in Dogs With Presumptive Sepsis: A Retrospective Study (2008-2018).

Background: In humans with sepsis, hypophosphatemia is a marker of illness severity and a negative prognostic indicator. Hypophosphatemia has not been previously investigated in dogs with sepsis, however. This study aimed to estimate the prevalence of hypophosphatemia in dogs, the prevalence of presumptive sepsis in dogs with hypophosphatemia, the prevalence of hypophosphatemia in dogs with presumptive sepsis and the association between outcome and hypophosphatemia in dogs with presumptive sepsis. Methods: Electronic medical records of the Cornell University Hospital for Animals from 2008-2018 were queried to identify all dogs with hypophosphatemia and all dogs with presumptive sepsis. Hypophosphatemia was defined as a serum phosphate concentration <2.7 mg/dL. Sepsis was presumed where ≥2 of 4 systemic inflammatory response syndrome (SIRS) criteria were satisfied associated with a documented or highly suspected infection. Variables were assessed for normality using the D'Agostino-Pearson test. Continuous variables were compared between groups using the Mann-Whitney U test. Differences in frequency between categorical variables were analyzed using contingency tables, calculation of Fisher's exact test or Chi2 and estimation of odds ratios. Results: In the study period, 47,992 phosphate concentration measurements from 23,752 unique dogs were identified. After eliminating repeat analyses, the period prevalence of hypophosphatemia on a per dog basis over the 11-year study period was 10.6% (2,515/23,752). The prevalence of presumptive sepsis within dogs with hypophosphatemia was 10.7% (268/2,515). During the 11-year study period, 4,406 dogs with an infection were identified, of which 1,233 were diagnosed with presumptive sepsis and had a contemporaneous phosphate concentration. Hypophosphatemia was more prevalent in dogs with presumptive sepsis than in dogs without 21.7 vs. 10.2%; OR 2.44 [95% CI 2.12-2.81]; P < 0.0001. The mortality rate was greater in dogs with hypophosphatemia and presumptive sepsis than in dogs with hypophosphatemia without presumptive sepsis (15.3 vs. 3.1%; OR 5.70 [95% CI 3.76-8.52]; P < 0.0001), however hypophosphatemia was not associated with outcome in dogs with presumptive sepsis OR 0.87 [95% CI 0.60-1.26]; P = 0.518. Conclusions: In dogs with hypophosphatemia, a presumed diagnosis of sepsis was associated with increased mortality compared to other associated disease processes. In dogs with presumptive sepsis, hypophosphatemia was not associated with outcome.
