GU/GYNE Flashcards
The inability to retract the foreskin over the glans penis is known as ___
Phimosis
What are the three etiologies of phimosis?
Congenital, balanitis, poor hygiene
What is the time course of congenital phimosis?
90% experience natural separation by age 3. It is considered normal for the foreskin to adhere to the glans until around age 6
Ok so phimosis is considered normal until age 6! Unless …
Unless urination results in ballooning of the foreskin at any age – this is abnormal
How does phimosis typically present?
Limitation and pain when attempting to retract the foreskin
What investigations are needed to diagnose phimosis?
None! Diagnosed based on history and physical
How do we manage phimosis?
Proper hygiene
Topical corticosteroids
Dorsal slit
Circumcision
10% of males that are not circumcised as newborns require circumcision as adults due to complications of phimosis and balanitis. What is a key risk factor for this?
Uncircumcised males with diabetes
If phimosis is the inability to retract the foreskin, then what is paraphimosis?
Paraphimosis is when the retracted foreskin cannot be returned to its normal position
True or false, routine circumcision is recommended in male infants.
False
What are some benefits of circumcision?
Decreased rates of UTIs and penile cancer. Decreased incidence of cervical cancer in female partners. Decreased HIV incidence of HIV infection in heterosexual men
What are risks of circumcision?
Procedural complications – bleeding, infection, phimosis, urinary retention, etc.
What are the top three causes of inguinal masses in children?
1 enlarged lymph node, followed by hernias and hydroceles
The prevalence of inguinal hernias in newborns is 1-4 in 100.
True or false, surgical correction is recommended.
True! The risk of incarceration is 60% in the first 6 months of life if hernia is left untreated
What is the most significant risk factor for hernias in babies?
Preterm birth (reported in 30% of babies weighing less than 1000 g at birth)
Inguinal masses can occur anywhere along the inguinal canal to the scrotum or labia. What are some differentials for an inguinal canal mass?
Enlarged lymph node, retractile testis, an ovary or a synovial cyst
Inguinal masses can occur anywhere along the inguinal canal to the scrotum or labia. What are some differentials for an inguinal ring mass?
Testis or ovary, or an inguinal hernia
Inguinal masses can occur anywhere along the inguinal canal to the scrotum or labia. What are some differentials for a scrotal mass?
Hernia, hydrocele, varicocele, trauma, testicular pathology
Inguinal masses can occur anywhere along the inguinal canal to the scrotum or labia. What are some differentials for a labial mass?
Trauma, ectopic ovary, mixed gonadal tissue, Bartholin cyst
Non-acute inguinal masses have a slow onset and are not painful – what are some differentials to consider for non-acute masses?
Lymphadenopathy, a retractile testis, hydrocele, hernia, varicocele, tumor, ectopic ovary
Acute inguinal masses have a sudden onset and are associated with pain – what are some differentials?
Epididymitis, orchitis, testicular torsion, traumatic hematoma, lymphadenitis, incarcerated hernia
Diagnostics to consider with an inguinal mass?
CBC (if suspecting infection)
Urine C&S/culture (if suspecting epididymitis, orchitis, STI)
US
Describe what is happening in testicular torsion
Twisting of the testicle causes venous occlusion and engorgement as well as arterial ischemia and infarction
How does testicular torsion present?
Sudden onset severe unilateral scrotal pain, swelling of scrotal sac, high position of the testicle, abnormal cremasteric reflex, negative Phren’s sign.
Pain may radiate to the lower abdomen/groin, may have N/V, scrotum may be indurated and erythematous, reactive hydrocele may occur
May report intermittent periods of testicular pain before torsion
What the heck is a negative cremasteric reflex?
The cremasteric reflex is a superficial reflex, when the inner thigh is stroked – yes stroked – the cremaster muscle should contract and pull the ipsilateral testicle toward the inguinal cancel (basically the scrotum contracts).
This won’t be present in testicular torsion
What the heck is a negative Phren’s sign?
Positive Phren’s sign is a relief of testicular pain with elevation of the scrotum – present with epididymitis
Phren’s sign is negative in testicular torsion
Your patient booked a same day appointment in your primary care clinic this morning, he has acute onset testicular pain with a negative cremasteric reflex and negative Phren’s - What do you do?
Transfer to ED – this is a surgical emergency
True of False – surgical intervention recommended within 4 hours
False – 2 hours. Surgical delay can lead to ischemia and a non-viable testis
The TWIST score can be used to help rule out the diagnosis of testicular torsion, what clinical findings do you think it considers?
TWIST score for testicular torsion (Up To Date)
*Nausea or vomiting: 1 point
- Testicular swelling: 2 points
- Hard testis on palpation: 2 points
- High-riding testis: 1 point
- Absent cremasteric reflex: 1 point
Score <2 excludes torsion with sensitivity 100%, specificity 82 %, negative PPV 100%
When would an orchiectomy be part of the surgical intervention? How about an orchiopexy?
Orchiectomy is done when the testicle is non-viable and needs to be removed
Orchioplexy is done bilaterally when TT occurs to prevent recurrence by anchoring the testes
At which ages does TT most commonly occur?
Small peak in neonatal period, large peak in adolescence. Can occur at any age.
How might TT present in infants?
Hardened, fixed, nontender scrotal mass with a discolored scrotum
What are some differentials for TT?
Epididymitis
Orchitis
Hydrocele
Testicular tumor (hard, enlarged, painless testicle)
Acute appendicitis
Varicocele
Scrotal/testicular trauma
Diagnostics for testicular torsion?
US – definitive diagnosis not required to go to OR if causing too much of a delay
T/F Only 10% of cases of acute scrotal pain are due to TT.
False – 40% of acute scrotal pain is diagnosed as TT
What is the most common STI? What about numero 2?
HPV is most common (30-60% of sexually active adolescents)
CT is the second most common
What are some possible complications of unmanaged CT?
10-15% rate of PID, ectopic pregnancy and chronic pelvic pain and infertility
Epididymitis occurs in 1-3% of urethral infection
What are some risk factors for STIs/complications in adolescents?
Increased risk-taking behaviors without considering long-term consequences
Inconsistent/incorrect use of condoms, unprotected sex
Multiple partners
Experimentation with drugs/alcohol
Mental health issues
Having an STI is a risk factor for future STIs
Poor adherence to antibiotics
Lack of access to education and STI services in certain places/ confidentiality concerns
Being female or MSM
T/F: Pubertal females are at higher risk of contracting G/CT than adult females
True - Pubertal females higher risk for G/CT due to immature histologic state of squamocolumnar junction
These cells are more vulnerable to infection and neoplastic changes, especially with exposure to tobacco or multiple episodes of new HPV infection
Use of oral contraceptives prolongs this immature state
What are common S/S of males with STIs?
Dysuria
Urethral pain or discharge
Testicular pain
Genital lesions – ulcers, vesicles, warts
Non-specific rash
Sexual partner with STI
What are common S/S for females with STIs?
Dysuria
Abnormal vaginal discharge
Intermenstrual or irregular menstrual bleeding
Dysmenorrhea
Dyspareunia
Post-coital bleeding
Lower abdo pain
Nonspecific rash, systemic symptoms (fever, N/V, malaise)
Genital lesions
Sexual partner with STI
T/F - STI testing is only done when symptoms are present
False, asymptomatic screening should be done at least annually – common to have asymptomatic infections
Which infections are reportable? What needs to be done with a reportable infection?
CT, G, syphilis, HIV
requires notification of all sexual partners within 60 days, of last sexual partner if > 60 days
Would you do a test of cure/re-test adolescents who you have treated for STIs?
Our book recommends yes – STIs are a risk factor for STIs, and reinfection for an untreated partner is common.
BC guidelines say to do a TOC when compliance in uncertain, patient not treated with recommended regimen or patient is pregnant. And to rescreen at 6 months, as reinfection rates are high
T/F: If a patient has CT, assume they also have G and treat for both infections.
False – it’s the other way – if a patient has G, then you treat empirically for CT as well. People test positive for G 7 days after contact, but do not test positive for CT until 2-6 weeks after contact, so if the G tests negative, then it probably is.
What is the recommended treatment for CT?
Doxycycline 100 mg po BID for 7 days
OR
Single dose azithromycin 1 G po
What is the recommended treatment for G?
Single dose cefixime 800 mg po
OR
Single dose ceftriaxone 250 mg IM
AND
CT treatment (Doxycycline 100mg po BID or azithromycin 1G po)
What are other important considerations in the management of CT/G?
Test and empirically treat all partners in past 60 days (or last partner if >60days)
Abstain from sex for 7 days after initiation of treatment
Test for other STIs
Rescreen in 6 months

-ADHD
What is the initial management of primary enuresis?
- Family counselling, address psychosocial stressors
- Advise that wetting is not intentional, punishment is inappropriate
- Limit fluids and caffeinated beverages in evening
- Reward chart for dry nights
- Conditioning therapy – use of an alarm that goes off when the child wets – assoc. With 70% success rate when used for 4-6 months
- Bladder retention training for those with small capacity bladders
- Address assoc. s/s such as encopresis or constipation.
How long do we try these initial measures
3-6 mo
What happens if initial measures are not working?
Consider medications
