Cutaneous Pythiosis in 2 Dogs, Italy.

We report cutaneous pythiosis in 2 dogs in Italy that had recurrent exposure to the same freshwater habitat. Phylogenetic analysis placed the isolates within Pythium insidiosum complex cluster IV, corresponding to P. periculosum. In Italy, pythiosis should be considered in differential diagnoses by human and veterinary health professionals.

Comparison of Dental Injury Rates in Perioperative Intubation and Suspension Laryngoscopy for Otolaryngology Procedures.

OBJECTIVE: Direct laryngoscopy is an essential skill during perioperative intubation and otolaryngology procedures. Dental injury is a common complication of direct laryngoscopy. However, the technique and tools used by anesthesiologists, nurse anesthetists, and others during perioperative intubation and by ear, nose, and throat surgeons for their procedures are different. The purpose of this review is to explore the literature for all studies detailing rates of dental injury in each of these settings and to compare them to see if the approaches have a significant difference in rate of dental injury. DATA SOURCES: PubMed. REVIEW METHODS: A comprehensive search of PubMed was performed through February 2021 with search terms "dental" and "intubation" or "laryngoscopy." PRISMA guidelines were followed. Studies documenting rates of dental injuries during intubation or during laryngologic procedures were included, and the 2 groups were compared. RESULTS: Twenty-three studies met inclusion criteria: 17 in the perioperative intubation group and 6 in the suspension laryngoscopy group. There was an increased incidence of dental injury in the perioperative intubation group (4.86%) as compared with the suspension laryngoscopy group (1.70%). CONCLUSIONS: The difference in dental injury rate between the groups could be due to the differences in direct laryngoscopy technique or tools used, the presence vs absence of a dental guard, or a combination of these factors. More studies need to be performed to develop definitive and specific conclusions to recommend changes that prevent dental injury.

Genetic variant in the NSDHL gene in a cat with multiple congenital lesions resembling inflammatory linear verrucous epidermal nevi.

BACKGROUND: The feline counterpart of human inflammatory linear verrucous epidermal nevus (ILVEN) has been described; however, the possible underlying developmental defect has not been investigated. OBJECTIVE: To report a case of multiple ILVEN-like lesions in a cat with a genetic variant in the NSDHL gene. ANIMALS: A 2-year-old, female, domestic short hair cat with a history of multiple alopecic, verrucous, hyperpigmented and erythematous skin lesions, following Blaschko's lines on the head, the limbs, the trunk and paw pads. METHODS AND RESULTS: According to the clinical and histopathological findings, a diagnosis of multiple ILVEN-like lesions was made. Genetic investigation revealed a heterozygous missense variant in the X-chromosomal NSDHL gene predicted to lead to a loss-of-function of the NSDHL protein. CONCLUSIONS AND CLINICAL IMPORTANCE: To the best of the authors' knowledge, this is the first case of feline ILVEN-like lesions in which a genetic cause has been proposed. Future studies to establish a causal relationship between NSDHL variants and skin lesions might lead to pathogenesis-directed treatments.

Fine-needle aspiration with selective use of core needle biopsy of major salivary gland tumors.

OBJECTIVES: Preferential use of fine-needle aspiration (FNA) versus core needle biopsy (CNB) for distinguishing benign from malignant major salivary gland tumors is highly debated. The main disadvantage of FNA is lower sensitivity, whereas arguments against CNB include use of a larger bore needle and greater risk of complications. The aim of this study is to evaluate our experience performing ultrasound-guided (UG) FNA with selective use of CNB based on preliminary cytopathology, and to determine whether our preoperative diagnostic approach is more sensitive and specific than FNA alone-and at least as sensitive and specific as CNB alone. STUDY DESIGN: Retrospective review of UG needle biopsy sampling of lesions arising in or around parotid and submandibular glands. METHODS: Ultrasounds of 141 needle biopsies were identified. Patient/lesion/needle biopsy characteristics, preliminary cytopathology, final pathology, imaging studies, and subsequent clinical course and treatment were documented. RESULTS: Needle biopsies performed according to our protocol provided results that guided clinical decision making in 125 of 135 cases, 92.6% (95% confidence interval [CI], 86.8%-96.4%) of the time. Using 41 cases that had histologic verification, sensitivity was 100% (95% CI, 79.6%-100%), and specificity was 92.3% (95% CI, 75.9%-97.9%) for detecting malignancy. We definitively characterized 120 lesions as benign (84) or malignant (36). CONCLUSION: Preoperative needle biopsy diagnoses allowed clinical management to progress 92.6% of the time. The protocol of FNA with selective use of CNB may potentially reduce patient exposure to risks associated with CNB without the tradeoff of lower sensitivity seen with FNA. LEVEL OF EVIDENCE: 4.

Two cases of paralitic ileus in onco-hematologic patients.

Paralytic ileus is a severe complication resulting from a variety of disorders. It occurs most commonly in patients with serious underlying medical or surgical conditions. Prompt diagnosis and appropriate management may improve the outcome. We describe 2 cases of onco-hematologic patients who presented this complication after intensive chemotherapy.

Malassezia spp. overgrowth in allergic cats.

A series of 18 allergic cats with multifocal Malassezia spp. overgrowth is reported: atopic dermatitis was diagnosed in 16, an adverse food reaction in another and one was euthanized 2 months after diagnosis of Malassezia overgrowth. All the cats were otherwise healthy and those tested (16 out of 18) for feline leukaemia or feline immunodeficiency virus infections were all negative. At dermatological examination, multifocal alopecia, erythema, crusting and greasy adherent brownish scales were variably distributed on all cats. Cytological examination revealed Malassezia spp. overgrowth with/without bacterial infection in facial skin (n = 11), ventral neck (n = 6), abdomen (n = 6), ear canal (n = 4), chin (n = 2), ear pinnae (n = 2), interdigital (n = 1) and claw folds skin (n = 1). Moreover, in two cats Malassezia pachydermatis was isolated in fungal cultures from lesional skin. Azoles therapy alone was prescribed in seven, azoles and antibacterial therapy in eight and azoles with both antibacterial and anti-inflammatory therapy in three of the cats. After 3-4 weeks of treatment, substantial reduction of pruritus and skin lesions was observed in all 11 cats treated with a combined therapy and in five of seven treated solely with azoles. Malassezia spp. overgrowth may represent a secondary cutaneous problem in allergic cats particularly in those presented for dermatological examination displaying greasy adherent brownish scales. The favourable response to treatment with antifungal treatments alone suggests that, as in dogs, Malassezia spp. may be partly responsible for both pruritus and cutaneous lesions in allergic cats.
