Abstract

Feline sporotrichosis is an endemic disease in Rio de Janeiro, Brazil, where zoonotic transmission of Sporothrix spp. has been reported since 1998. Itraconazole (ITZ) remains the first choice for treating this disease in cats. However, there have been reports of therapeutic failure and a long-term endeavor. Potassium iodide (KI), considered in the past as a drug with variable effectiveness in cats with sporotrichosis, arises as an important option in the treatment of cats from the endemic area of Rio de Janeiro. In order to evaluate the effectiveness of the association of ITZ and KI in naive cats with sporotrichosis, a prospective cohort study was conducted on 30 cats receiving ITZ 100 mg/day and KI 2.5 mg-20 mg/kg/day. Clinical and laboratory adverse effects were assessed once a month according to the standard care protocol. The cure rate was 96.15% within a median of 14 weeks of treatment. Adverse effects were observed in 50% of cats and were managed with a temporary drug suspension and/or a hepatoprotective therapy. The association of ITZ and KI emerges as an effective option for the treatment of feline sporotrichosis.

Reversible control of reproduction in tom cats: medical options for manipulating libido and fertility.
This review focuses on the hormonal drugs for controlling reproduction in male cats currently available to feline practitioners. The reversibility of their effects, which is due to temporary suppression of testosterone secretion and spermatogenesis, makes this option appealing for breeders. The different compounds are described.

Use of surgical lasers in small animal dermatology
This article covers the basics of lasers, including discussion of both diode and CO2 lasers. It also discusses several skin diseases and/or conditions in which lasers are commonly used.

Clinical Utility of Cytology from Preoperative Percutaneous Fine Needle Aspirates of Solitary Liver Masses in 220 Dogs: A Retrospective Study (2009-2019).
The agreement rate for correct cytologic diagnosis was 22.9% (49/220). Of the neoplastic masses 18.9% (35/185) were correctly diagnosed via cytology. The overall sensitivity was 60%, and the specificity was 68.6%. Neither institution, lesion size, cavitation, or needle gauge had an association with correct diagnosis. This study demonstrates that, although there is a low risk of complications following FNA of a hepatic mass, overall success rate for correct cytologic diagnosis based on FNA was low compared to histopathologic diagnosis.

Intrathecal mepivacaine after general anesthesia is an effective method of equine euthanasia when compared to intravenous pentobarbital.
Previous publications have shown that the risk of scavenger intoxication through consumption of the carcass is low with an intrathecal lidocaine method. In horses euthanized with intravenous pentobarbital, sodium pentobarbital residues were found in compost pile samples up to 367 days after euthanasia with no decrease in concentration, despite complete degradation of soft tissues.

Uroabdomen: Approach and Management
Animals with uroabdomen caused by small defects can potentially be medically managed with intravenous fluid therapy and urinary diversion (with a urinary catheter and/or abdominal drain). In a recent study, 25% of cats with uroabdomen were medically managed, and in another study, 14% of dogs were treated with medical management alone. Otherwise, uroabdomen is generally considered a surgical condition once the patient has been stabilized.
