Abstract

External otitis is a commonly encountered ear disease in cats, characterized by inflammation of the external auditory canal and influenced by predisposing, primary, secondary, and perpetuating factors. This case report describes a six-year-old male Persian cat with a history of recurrent external otitis. The cat was presented to the Internal Medicine Laboratory, Faculty of Veterinary Medicine, Udayana University, Denpasar, Bali, with primary complaints of frequent ear scratching, head shaking, and the presence of yellow, foul-smelling discharge from both ears. Physical examination revealed yellowish, watery cerumen with a strong odor. Cytological examination demonstrated abundant rod-shaped bacteria, and bacterial culture confirmed the growth of Proteus spp. A diagnosis of bilateral external otitis caused by Proteus spp. infection was established, with a favorable prognosis. The treatment consisted of topical administration of Topigen® ear drops containing gentamicin sulphate (1.6 mg/mL), nystatin (100,000 IU/mL), and fluocinolone acetonide (0.25 mg/mL), administered at a dosage of three drops twice daily for 12 days, accompanied by routine ear cleaning using an otic cleansing solution. Clinical evaluation after 12 days of treatment showed significant improvement, characterized by reduced cerumen production, resolution of malodor, and the absence of inflammatory signs on otoscopic examination. This report underscores the importance of cytological examination and bacterial culture in establishing an accurate diagnosis and demonstrates the effectiveness of combination topical antibiotic and anti-inflammatory therapy in the management of bacterial external otitis.

Abstract

Cranberry (Vaccinium macrocarpon) extract contains proanthocyanidins (PACs), anthocyanins, and flavonols, which act as antioxidants that protect kidney tissue through antioxidant activity and reduced oxidative stress and proinflammatory cytokine production. Urolithiasis is a urinary tract disorder characterized by the formation of crystals, excess sediment, uroliths, or calculi, which can block urine flow, causing back pressure on the kidneys and leading to hydronephrosis. This case report discusses the management of a 4-year-old domestic male cat that exhibited clinical symptoms of urinary tract obstruction and straining. Clinical signs of urinary tract obstruction were observed for one week. The diagnosis was made based on history, clinical signs, hematology, blood chemistry, urinalysis, and ultrasonography. Hematology examination results indicated lymphocytosis, granulocytopenia, and thrombocytopenia, while blood chemistry showed hypertotal proteinemia, hyperglobulinemia, and hypokalemia. Urine chemistry analysis showed positive leukocytes, protein, pH 7.5, specific gravity 1.010, and urine microscopy revealed struvite crystals and calcium oxalate. Ultrasonography revealed hyperechoic crystal particles in the lumen of the urinary bladder and dilated left renal pelvis. This case was diagnosed as urolithiasis and unilateral left hydronephrosis. Therapy included urinary catheter placement, 0.9% physiological NaCl flushing, 250 mg cranberry extract q24h PO, and special diet for kidney problems. Evaluation showed clinical improvement marked by the absence of stranguria and oliguria, although urinary crystals and dilated left renal pelvis were still detected on ultrasound examination. The owner was advised to monitor the urinary tract through urinalysis and ultrasound periodically, implement a special diet for kidneys and adequate water intake.

Abstract

Malassezia dermatitis is a common skin disease in dogs caused by the overgrowth of Malassezia sp., a lipophilic yeast that normally inhabits the skin but may act as an opportunistic pathogen when skin homeostasis is disrupted. This yeast is commonly found in areas with active sebaceous glands and may cause pruritus, alopecia, hyperpigmentation, and chronic skin changes. This report describes a case of a 3-month-old female domestic puppy named Stella, weighing approximately 3 kg, presenting with chronic pruritus accompanied by generalized hair loss that had persisted for approximately one month. Dermatological examination revealed alopecia on the face, ears, neck, and extremities, along with hyperpigmentation, crust formation, and skin thickening consistent with lichenification. Supporting examinations using acetic acid tape preparation (ATP) cytology demonstrated a high number of Malassezia sp., while skin scraping and otic swab examinations did not reveal the presence of ectoparasites or other infectious agents, and trichogram analysis showed a predominance of hairs in the telogen phase, indicating chronic skin stress. The therapy administered consisted of bathing with Sebazole® shampoo as the primary treatment, topical application of apple cider vinegar and virgin coconut oil (VCO) as adjunct therapies to support skin barrier repair, and administration of diphenhydramine as symptomatic therapy to reduce pruritus. After four weeks of treatment, the clinical condition of the case animal showed significant improvement leading to complete recovery, characterized by the resolution of pruritus, skin lesions, and alopecia, along with hair regrowth.

Abstract

Psychogenic alopecia is hair loss caused by behavioral disorders that lead cats to groom excessively, resulting in skin lesions. Compulsive grooming causes alopecia, erythema, and secondary skin lesions. This case report discusses a Persian cat with complaints of alopecia, redness, and crusting without any infectious agents being found. Physical examination revealed self-induced alopecia, with pre-existing conditions within normal limits and a body condition score (BCS) of 5/9. Overall, the cat exhibited a docile temperament and normal activity levels. Complete blood count results were within normal ranges. The cat showed significant improvement after antihistamine therapy, a special diet for skin and hair, and grooming with hypoallergenic shampoo in a low-stress environment. However, relapse occurred after returning home to an environment with a high cat population. The cat recovered again after the owner provided more attention by regularly interacting and playing with it. Based on the history, examination findings, and therapeutic response, the diagnosis was established as suspected psychogenic alopecia with secondary dermatitis triggered by environmental stress.
