Q

semen storage in the epididymis; how is amount controlled

A

◦ Epididymis can only hold so much as sperm is constantly being produced
◦ Epididymis produces alkaline phosphatase (ALP) – can be used to determine if there is a blockage in sperm transpor

Q

diagnosis of cryptorchidism and what is it associated with

Study These Flashcards
A

Diagnosis:
◦ Palpation
◦ Abdominal ultrasound

Important condition because associated with:
◦ Testicular neoplasia
◦ Testicular torsion

23
Q

primary testicular neoplasia; what type of dogs is it common in, types, incidence, unilateral vs bilateral

Study These Flashcards
A

Common in dogs
◦ Usually older
◦ Cryptorchids

Types:
◦ Sertoli cell tumor
◦ Seminoma
◦ Interstitial cell tumor (Leydig cell tumor)

-Incidence roughly 1/3rd for each

-Bilateral involvement is common

-Multiple types can occur concurrently
◦ Mixed neoplasia

24
Q

sertoli cell tumor; when is it more common, is metastasis common, what syndrome do you see with it

Study These Flashcards
A

-More common in retained testes
-Paraneoplastic syndrome
-Metastasis; Not common

25
paraneoplasic syndrome features with sertoli cell tumors
◦ FEMINIZATION ◦ Behavioral change, alopecia (bilateral symmetrical), gynecomastia, hyperpigmentation, pendulous prepuce, squamous metaplasia of the prostate, attraction to males, decreased libido Pancytopenia – life threatening ◦ 1st transient increased granulopoiesis with peripheral neutrophilia ◦ Then, neutropenia, thrombocytopenia & non regenerative anemia ◦ Bone marrow replaced by fibrous tissue + fat
26
leydig/interstitial cell tumor; when is it more common, what can it secrete, does it metastasize, what can it secrete
-More common in descended testes; Rare reports of interstitial cell tumors in cryptorchid testes Can secrete estrogen or testosterone ◦ Similar clinical signs to SCT if estrogen producing ◦ If hypertestosteronism: Perinal adenomas, perineal hernia, prostatic disease -Usually diagnosed incidentally unless steroid producing -Very rare to metastasize
27
what do interstitial cell tumors look like grossly
* Soft * Yellow-orange * Cystic with serous/ serosanguineous fluid
28
seminoma; occurs in what, what can it produce
-Often occur in retained testes -Can produce steroids occasionally (estrogens) -Rarely metastasize -Carcinoma in situ (CIS)
29
what does a seminoma look like grossly
* Soft * Homogenous * Ivory color * +/- lobulation * Smaller but can get large
30
what is the supportive care of paraneoplastic syndrome
◦ Blood transfusion ◦ Broad spectrum antibiotics (secondary infections) ◦ Fluid therapy
31
what is the prognosis of sertoli cell tumors and how to prevent it
Prognosis; Unfavorable if severe pancytopenia -Prevention is key – castrate cryptorchids
32
other differential dx for scrotal symmetry (6)
◦ Orchitis ◦ Scrotal hernia ◦ Scrotal abscess ◦ Testicular torsion ◦ Epididymitis ◦ Trauma
33
what is the most common clinical sign of benign prostatic hyperplasia (BPH)
Serosanguinous fluid dripping for the penis or blood in semen/urine
34
what are four conditions of the prostate
◦ Benign Prostatic Hypertrophy (BPH) ◦ Prostatitis ◦ Prostatic cysts ◦ Prostatic Adenocarcinoma
35
diagnosis and treatment of BPH
Diagnosis: ◦ Often found incidentally ◦ Detection of blood in prostatic fluid of the ejaculate/on tip of penis ◦ Uniform prostatic enlargement by palpation, radiographs, ultrasound Treatment: ◦ Goal = decrease prostatic size ◦ Castration – works fastest ◦ Medical ◦ Finasteride - works by acting on the enzyme that converts testosterone to DHT (5⍺-reductase) – breeding males ◦ Anti-androgens, progestagens Important to treat as predisposes to other prostatic disease if left untreated
36
why/how does BPH occur? what population does it occur in? how common? what does it cause?
Prostatic growth & secretion ◦ Occurs in response to testosterone metabolite → dihydrotestosterone (DHT) BPH = Spontaneous, age-related condition of intact males Common condition: >80% of intact males >6 age old have BPH Causes prostate gland enlargement ◦ Prostatic volume in affected dogs is 2-6.5x greater than normal dogs of equal size
37
details of retention cysts (6)
◦ Occur as BPH progresses ◦ Can be multiple small cysts and/or 1-2 large cysts ◦ Contain serosanguineous fluid ◦ Clinical signs → similar to BPH ◦ Rarely need surgical treatment or drainage ◦ Can lead to prostatic abscess if left untreated
38
details of paraprostatic cysts (3)
◦ Cysts adjacent to prostate ◦ Can get quite large; Clinical signs: dysuria, tenesmus, perineal hernia → space occupying Treatment ◦ Surgical removal ◦ Drainage via ultrasound guidance
39
two types of prostatitis
acute and chronic prostatitis
40
acute prostatitis; how common, type of illness, clinical signs, diagnosis and treatment
* Not common * Severe, acute illness – systemic involvement ; Neutrophilia Painful * Abdominal pain * Pain on palpation of prostate * Prostate is enlarged * Difficulty walking (hunched up) * Fever * Culture is important for diagnosis & treatment (From urine) * Prostatic barrier not intact * Base antibiotics on sensitivity * Supportive care as needed
41
chronic prostatitis; how common, type of illness, clinical signs, cause, treatment
* More common * Subclinical/low grade disease; Recurring urinary tract disease or subfertility * 2nd to BPH, urinary disease * Urethral discharge * Hemospermia * Enlarged irregular prostate * Commonly caused by commensals; E.coli * Prostatic barrier is intact * Need to take this into account for antibiotic selection * Typically do not need supportive care
42
what happens if you dont treat prostatitis
can lead to prostatic abscess
43
what type of medications can you NOT use for prostatitis? what should you use instead? length of treatment
DONT USE -Penicillins -Cephalosporins -Aminoglycosides USE -Fluoroquinolones -Trimethoprim/sulfa -Chloramphenicol -Doxycycline minimum 4-6 weeks, recheck often
44
prostatic neoplasia; how common/in who, metastasis, prognosis
-Uncommon -More common in neutered males -Prostatic adenocarcinoma = most common -Transitional cell carcinoma (TCC) = also possible -HIGH rates of metastasis -Prognosis is GRAVE
45
what does it mean if you see dysuria?
* Means it is not BPH Indicative of something more serious: * Prostatitis * Abscess * Cyst * Tumo
46
what do you need to rule out if you suspect orchitis/epididymitis
brucella canis
47
when and where does TVT occur
-Common in tropical, subtropical regions → rescue dogs in NA -Usually occurs in younger, sexually mature dogs, free roaming ◦ Can occur in castrated/spayed dogs
48
is a dog has no sperm and low ALP, what kind of problem is that
If have a dog with no sperm (azoospermia) and ALP is low = suggestive of a tubing problem
49
what will you see with priapism
-Persistent erection (>4hrs) -Look for cause -Can be idiopathic -Conservative tx similar to paraphimosis -Ravage, medications, amputation
50
cytology; what does it count, scores
Counting non-sperm cells (Inflammatory cells) Cytology scores (# of cells/ high power field – HPF) ◦ 0 = <1 ◦ 1+ = 1-3 cells/hpf ◦ 2+ = 4-6 cells/hpf ◦ 3+ = 7-10 cells/hpf
51
how can you calculate the total number of sperm in ejaculate (2)
◦ Concentration ◦ Volume
52
fractions of sperm in the dog
◦ 1st: prostatic → flushing out the urethra → urine and debris ◦ 2nd: sperm rich + fluid from epididymis ◦ 3rd: prostatic – lots of volume
53
components of semen evaluation (6)
◦ Color, consistency ◦ Motility ◦ Concentration ◦ Volume ◦ Number of sperm ◦ Morphology
