Q

Identify the condition pictured. How would you treat it?

A

Chin acne
While the exact mechanism is not understood, the abnormal follicular keratinization is thought to be related to a primary seborrheic disease such as excessive sebum production (natural oil produced by the skin). Stress, viral infection, immunosuppression, allergies, or poor grooming habits may also play a role. Unfortunately, none of these conditions have been proven to be the cause of feline acne

Tx: Hydrogen peroxide or benzoyl peroxide. Shave area prior to application

Q

An 82-1b (37-kg), 8-year-old neutered male German Shepherd mixed-breed dog is being evaluated because of a two-month history of decreased exercise tolerance. The client reports that the dog had two episodes of “profound weakness” on walks during the past week. The dog seems comfortable at home, but his “heart is racing all the time.” Two years ago, another veterinarian diagnosed the dog with hypothyroidism and prescribed oral levothyroxine 0.8 mg twice daily. Dosage was reevaluated one month after initiation of treatment and was determined appropriate. Appetite, urination, and bowel movements are normal. Body condition score is 6/9. Temperature is 101.2°F (38.4°C) and heart rate is 180 beats/min. The dog is panting.
Physical examination detects a pulse deficit that occurs three to five times each minute. No other abnormalities are noted.
Results of complete blood count, serum biochemistry profile, and urinalysis are within normal limits. Which of the following is the most likely explanation for the episodic weakness in this dog?

A

Decreased cardiac output

Q

A 5-year-old female West Highland White Terrier dog is brought back to the clinic ten days after being diagnosed as having pyoderma. Physical examination at the time had shown papules, pustules, and epidermal collarettes predominantly distributed in the inguinal region. A two-week course of trimethoprim-sulfadiazine at a standard dose was prescribed, and the client reported clearing of the lesions within a few days. The dog has now developed spreading, circular, bull’s-eye, erythematous lesions on the thorax and forelimbs. There are some papules but no erosion or ulceration. A skin biopsy is obtained. Which of the following is the most appropriate next step pending results of the skin biopsy?

A

Discontinue all therapy

Q

What is the most common coccidia of cats and dogs? What are the clinical signs? How is it diagnosed? Treatment?

A

Isospora spp.

Most infected dogs and cats do not display clinical signs. Acute cases are associated with diarrhea. In severe cases you may see blood in the stool.

Fecal flotation is used to diagnose this condition.

Infection usually spontaneously resolves. A sulfa AB (e.g. sulfadimethoxine) can be used in clinically ill patients.

Q

A 4-year-old female Maltese dog has had the progressive onset of tremors, excitability, and panting during the past hour. She has had two tonic seizures during this time. The dog whelped five healthy puppies four weeks ago. Her temperature is 103.9°F (39.9°C). On examination, the dog is very anxious, has muscle tremors, and is hyperresponsive to tactile stimulation. Which of the following is the most appropriate immediate pharmacologic treatment of this dog?
A) Calcium gluconate intravenously
B) Dexamethasone intravenously
C) Diazepam intravenously
D) Phenobarbital intravenously
E) Potassium bromide orally

A

A
In this case, the symptoms and the history suggest that the Maltese may be experiencing eclampsia, a condition that can occur in nursing females due to low calcium levels. The signs of tremors, excitability, panting, seizures, and hyperresponsiveness align with this condition.

Given that eclampsia is typically treated with calcium supplementation, calcium gluconate would be the appropriate choice. It helps to rapidly increase calcium levels in the blood, which can alleviate the neurological signs and prevent further seizures.

Diazepam, while useful for managing seizures, would not address the underlying cause of the tremors and seizures related to hypocalcemia. Therefore, in this scenario, calcium gluconate is the correct treatment to administer.
