42
Q

Is HSV-1 more common in primary or recurrent genital infections?

A

Up to 30% of primary genital herpes infections can be HSV-1. HSV-1 is rarely seen in recurrent genital herpes.

43
Q

Classification of genital HSV infections

A

INITIAL: no hx of herpes and seronegative, systemic symptoms (fever, headache, malaise and myalgias usually precede the onset of genital lesions), vulvar lesions begin as tender grouped vesicles that progress into exquisitely tender, superficial, small ulcerations on an erythematous base. INITIAL NON-PRIMARY: first recognized episode of genital herpes in individuals who are seropositive for HSV. Prior HSV-1 infection confers partial immunity to HSV-2 and lessens the severity of HSV-2 infection. There is less pain, fewer lesions, more rapid resolution of clinical lesions and shorter duration of viral shedding than initial infection. Systemic symptoms are rare. RECURRENT: reactivation of HSV-2 with episodic prodromal symptoms and outbreaks of lesions at varying intervals and of variable severity.

44
Q

Diagnosing HSV infection

A

Viral culture, antigen detection and serology.

45
Q

Treating HSV infection

A

Acyclovir, famcyclovir or valacyclovir. Sitz baths and topical xylocaine can help relieve burning and irritation.

50
Q

Ascending bacteria that can cause salpingitis

A

Chlamydia, gonorrhea, E. coli, Klebsiella, G. vaginalis, Prevotella, Group B streptococcus and enterococcus.

51
Q

Inpatient treatment of a patient with suspected salpingitis due to chlamydia and/or gonorrhea who cannot tolerate oral medications due to nausea and vomiting.

A

IV cefotetan or cefoxitin PLUS doxycycline. Or clindamycin PLUS gentamicin.

52
Q

A

50-60cc. Overflow incontinence has PVR > 300cc.

56
Q

Most common causes of GSI

A

Genuine Stress Incontinence is urine loss due to increased abdominal pressure with normal detrusor function. The majority of GSI is caused by urethral hypermobility (straining Q-tip angle >30 degrees from horizon). Some (

57
Q

Treatment for GSI due to urethral hypermobility

A

Retropubic urethropexy such as tension-free vaginal tape and other sling procedures

58
Q

Treatment for GSI due to intrinsic sphincteric deficiency and no urethral hypermobility

A

Urethral bulking

59
Q

Medications used to treat urge incontinence due to detrusor muscle instability

A

1) Oxybutinin: anti-muscarinic that blocks ACh stimulation of detrusor muscle. 2) TCAs can do the same thing, but side effects make them less desirable.

60
Q

Medication that can be used to help with stress incontinence by stimulating alpha-adrenergic receptors

A

Pseudoephedrine

61
Q

Fascial defect in rectoceles, how do you fix it?

A

62
Q

Fascial defect in cystoceles, how do you fix it?

A

Pubocervial fascia. Anterior repair.

63
Q

What causes mixed incontinence?

A

Increased intra-abdominal pressure causes the urethral-vesical junction to descend causing the detrusor muscle to contract.

64
Q

In what patient population is colpcleisis a good option for treatment of vaginal prolapse?

A

The vagina is surgically obliterated and can be performed quickly without the need for general anesthesia. Good for patients with comorbidities that prevent them from going under general anesthesia for sacrospinous fixation (cuff to sacrospinous-coccygeus complex) or sacrocolpopexy (cuff to sacral promontory using interposed mesh).

65
Q

Next step in care when u/s shows a complex ovarian cyst in an asymptomatic post-menopausal female

A

Exploratory surgery, u/s is best imaging modality and you must take it out due to risk of ovarian cancer.

66
Q

1st line treatment for endometriosis

A

1) NSAIDs 2) OCPs provide negative feedback to the pituitary-hypothalamic axis which stops stimulation of the ovary to produce sex hormones, such as estrogen, which stimulates endometrial tissue located outside of the endometrium and uterus. 3) Laparoscopy to clear adhesions

67
Q

Definitive diagnosis for ovarian torsions

A

Surgical exploration, doppler u/s may be normal because ovarian blood supply can be maintained despite torsion

68
Q

Presentation of patients with interstitial cystitis

A

Recurrent irritative voiding symptoms of urgency and frequency, in the absence of objective evidence of another disease that could cause the symptoms. Some may also have dysmenorrhea and dyspareunia.

69
Q

Rome II criteria for IBS

A

At least 12 weeks (need not be consecutive) in the preceding 12 months of abdominal discomfort or pain that has two of three features: 1) Relief with defecation; 2) Onset associated with a change in frequency of stool; or 3) Onset associated with a change in stool form or appearance.

70
Q

How does Danazol help with treatment of endometriosis?

A

It is a 17-alpha-ethinyl testosterone derivative, which suppresses the mid-cycle surges of LH and FSH.

71
Q

What drugs are more effective than Danazol in treatment of endometriosis?

A

GnRH analogues. They down-regulate hypothalamic-pituitary gland production and release of LH and FSH leading to dramatic reductions in estradiol level.

72
Q

40-50% of women with chronic pelvic pain may also have a history of what?

A

Abuse

73
Q

Presentation of pelvic congestion syndrome

A

Pelvic fullness or heaviness that is worse premenstrually, during pregnancy, with standing, coitus and fatigue. Patients may also have pain that radiates to the vulva, vaginal discharge, backache, dysmenorrhea and urinary frequency.

74
Q

Cause of pelvic congestion syndrome

A

Vasodilatation occurs when pelvic veins are exposed to high concentrations of estradiol, which inhibits reflex vasoconstriction of vessels, induces uterine enlargement with selective dilatation of ovarian and uterine veins resulting in pelvic varicosities.

75
Q

Where is the iliohypogastric nerve at risk for damage and what symptoms would patients have?

A

The iliohypogastric nerve travels on top of the psoas until it reaches the ASIS when courses medially between the internal and external oblique muscles, becoming cutaneous 1 cm superior to the superficial inguinal ring. It supplies cutaneous sensation to the groin and the skin overlying the pubis.

76
Q

Where is the ilioinguinal nerve at risk for damage and what symptoms would patients have?

A

The ilioinguinal nerve travels on top of the psoas beneath the iliohypogastric and also courses between the internal and external obliques until it becomes cutaneous 1cm superior the the superficial inguinal ring. It supplies cutaneous sensation to the groin, symphysis, labium and upper inner thigh.

77
Q

Major risk factors for breast cancer

A

Gail model: Old age, Early age at menarche, Late age at 1st childbirth, 1st degree relative, previous breast biopsy, biopsies with atypical hyperplasia, race/ethnicity

78
Q

Test to do if a woman presents with bloody nipple discharge

A

Ductogram

79
Q

Test to do if a post-menopausal woman presents with white nipple discharge

A

Fasting prolactin levels, if elevated do brain MRI to r/o pituitary tumor. If MRI is normal move on to r/o other causes of elevated prolactin levels like hypothyroidism, hypothalamic disorders, chest lesions (breast implants, thoracotomy scars, and herpes zoster) and renal failure.

80
Q

What breast disease would you recommend a decrease in caffeine intake

A

Fibrocystic changes. Caffeine elevates cortisol levels, cortisol alters sex hormone levels and changes breast composition.

81
