Q

People with suspected syphilis who decline testing, and people diagnosed with syphilis who decline treatment, should be advised what?

A

if they are found to have infected other people with syphilis via unprotected sexual contact or non-sexual contact with active lesions, despite knowing that this could occur, they may be subject to prosecution.

Q

False negative serology in syphilis testing?

A

Treponemal screening tests are negative before a chancre develops and remain negative for up to two weeks afterwards.

A false-negative RPR/VDRL test may occur in secondary or early latent syphilis — this may be more likely to occur in people co-infected with HIV.

The RPR/VDRL and IgM may be negative in late syphilis.

increased risk of vulval ca

320
Q

When may biopsy be performed for lichen sclerosus?

A

if atypical features, uncertain or is suspicious of neoplastic change.

Pts under routine follow up will need a biopsy if:
(i) there is a suspicion of neoplastic change, i.e. a persistent area of hyperkeratosis, erosion or erythema, or new warty or papular lesions;
(ii) the disease fails to respond to adequate treatment;
(iii) there is extragenital LS, with features suggesting an overlap with morphoea;
(iv) there are pigmented areas, in order to exclude an abnormal melanocytic proliferation;
and
(v) second-line therapy is to be used.

355
Q

Features of oral herpes?

A

Herpes labialis= prodrome of fever, sore throat, and lymphadenopathy, particularly in primary infections.

Initial symptoms= pain, burning, tingling, and itching may precede visible lesions and typically last 6–48 hours.

Herpes labialis lesions are typically crops of vesicles that rupture, ulcer, crust, and heal (usually without scarring).

Herpes gingivostomatitis lesions are typically crops of painful vesicles that rupture and form ulcers on the pharyngeal and oral mucosa.

People who are immunocompromised may have severe, atypical lesions anywhere in the oral cavity.

356

A
  • immunocompromised with troublesome infection
  • pregnant
  • severe, frequent or persistent infections
  • associated recurrent erythema multiforme
  • lesions are refractory to primary care Tx
  • lesions are atypical
360
Q

Mx for oral herpes?

A
  • analgesia for pain and fever
  • consider oral antiviral (aciclovir, min 5 days, from prodome symptoms before vesicles appear and until healed): if primary infection, recurrent lesions are severe frequent or persistent or for recurrent gingivostomatitis (rare). Also if immunocompromised and primary or recurrent infection.
  • Advise that topical antiviral preparations, topical analgesics, mouthwash, and lip barrier preparations are not routinely recommended, but some people may find them helpful, and they are available over-the-counter.
  • self-care advice to avoid trigger factors and to reduce risk of autoinoculation and transmission to others
  • sunscreen or sunblock lip balm for recurrent infections triggered by sunlight
361
Q

Ocular herpes simplex virus infections?

A

can cause inflam of retina (retinitis), iris and associated uveal tract (iritis or uveitis), cornea (keratitis), conjunctiva (conjunctivitis), eyelids (blepharitis) and surrounding skin (periocular dermatitis)

What usually causes ocular herpes?

A

HSV1

363
Q

Features of ocular herpes?

A

most asymptomatic

if symptomatic, usually presents with blepharoconjunctivitis

364
Q

Recurrent HSV ocular infection

A

more common clinically, and lesions typically cause keratitis which may affect one or more of the three corneal layers:

Epithelial — the most common ocular manifestation of HSV infection, accounting for 50–80% of cases.

Stromal — which may be non-necrotizing or necrotizing.

Metaherpetic ulcer (trophic keratitis).

365
Q

Ocular HSV transmission?

A

direct contact with active orofacial lesions or infected secretions such as saliva or tears, from a person who is actively shedding the virus.

HSV persists in a latent state in the trigeminal nerve ganglion, where it can remain latent indefinitely or can reactivate, leading to viral shedding at the corneal surface.

366
Q

Cx of ocular herpes?

A

Corneal scarring and visual impairment.

Corneal perforation.

Secondary infection with bacteria or fungi.

Systemic infection, such as aseptic meningitis, encephalitis, or hepatitis.

367
Q

Prognosis of ocular HSV?

A

Blepharoconjunctivitis tends to resolve within 2 weeks, and epithelial keratitis tends to resolve in 1–2 weeks.

About 25% of people with epithelial keratitis will develop stromal keratitis or iritis.

Recurrent ocular HSV is common, with the risk increasing after each subsequent episode.

368
Q

Symptoms and signs of ocular herpes?

A

Eye pain, eye irritation or watering, and photophobia.

Blurred vision.

An acute red eye.

Crops of vesicles, ulcers, or pustules along the lid margin or periocular skin.

A hazy cornea or creamy opacity (suggests stromal keratitis).

A fixed irregular pupil or limbal injection (suggests iritis or uveitis).

Reduced corneal sensation.

Reduced visual acuity.

369
Q

Diagnosis of ocular herpes?

A

clinical examination to check for systemic infection, such as pyrexia, lymphadenopathy, and hepatosplenomegaly.

Fluorescein staining of the cornea to check for a dendritic or amoeboid ulcer, suggesting epithelial involvement.

Checking visual acuity.

370
Q

Mx of ocular herpes?

A

Referral of all cases to eye casualty or an emergency eye service for same-day assessment and specialist management.

If same-day assessment is not possible or practical, specialist ophthalmological advice should be sought regarding initiating drug treatment in primary care.

Note: some optometrists can initiate topical antiviral treatment for suspected epithelial keratitis in specific clinical circumstances.
