Q

Risk factors for gout?

A
  • Dehydration
  • Diet: purine rich substances e.g. meat, seafood, alcohol, fructose-sweetened drinks
  • Disorders of high cell turnover e.g. haematological malignancies, severe psoriasis

Q

What are the options for gout flare prophylaxis when initiating or titrating urate lowering therapy and how long are they usually required?

A
  1. Colchicine 500microg daily or BD PO
  2. NSAID orally on lower dosing end
  3. Prednisone 5mg daily PO

Colchicine can be used in conjunction with either NSAID or prednisone. Do not use NSAID and prednisone. Prednisone should be used in consultation with rheumatologist due to side effects.

Duration: 3 to 6 months

Q

What is trichiasis and what is its significance?

A
  • Trichiasis is defined as normal lashes growing inward. In trichiasis, the lash follicle is normal, but the direction of lash growth is abnormal. In the presence of inflammation, there may be a misdirection of the follicle with the lash growing inwards towards the cornea
  • Where trachoma is endemic, trichiasis of any degree indicates trachoma until proven otherwise

Q

What is systemic sclerosis, how is it classified and what are its key features?

A

Systemic sclerosis is an autoimmune inflammatory condition that results in widespread fibrosis and vascular abnormalities

It is subdivided according to the distribution of skin involvement
- Diffuse cutaneous systemic sclerosis
- Limited cutaneous systemic sclerosis (previously CREST syndrome) —- confined to the fingers, distal portion of the extremities, and the face

Limited cutaneous systemic sclerosis (CREST syndrome):
- Calcinosis
- Raynaud’s phenomenon
- Oesophageal dysmotility
- Sclerodactyly
- Telangiectasias

Key features:
- Skin thickening of the fingers and toes (sclerodactyly)
- Specific autoantibodies (anti-Scl70 or anti-centromere)
- Abnormal nail fold capillaries
- Internal organ fibrosis and/or vascular damage

Questions to ask when assessing patchy hair loss/alopecia areata and differentials?

A

  • Cold/heat intolerance OR unintentional weight change (thyroid disorder)
  • [Past history of vitiligo OR autoimmune disease] or [Arthralgia OR other rashes] (symptoms of possible autoimmune disease)
  • Past history of dermatitis OR alopecia areata
  • Localised tingling OR itching in the preceding weeks (trichodynia)

  • Excessive OR irresistible urge for hair pulling OR obsessive compulsive disorder (trichotillomania)
  • Significant stressors OR anxiety (telogen effluvium)
  • Preceding redness OR scaliness of scalp OR pet dogs or cats - Tinea capitis

Q

What is alopecia areata and who gets affected?

A

Alopecia areata: autoimmune condition affecting hair follicles causing hair loss and typically presents with discrete bald patches on the scalp but can cause hair loss from all hair-bearing areas on the body

Peak incidence occurs in second and third decades and most patients experience onset before the fourth decade

Groups at increased risk of alopecia areata:
- Other autoimmune conditions such as vitiligo and thyroid disease
- A family history of alopecia areata

Q

What is required for patients considering Q fever vaccination?

A
  • Q fever skin test
  • Serum Q fever antibody test

Rationale: to identify people who have been previously infected with the Q fever organism and not aware of it. These people are likely to have adverse reactions to the vaccine, based on hypersensitivity to the organism

Patients previously infected with Q fever should not be vaccinated

64

- Consider dermatitis if significant itching and/or rash
- Consider nipple vasospasm if exacerbated by cold and/or nipples blanch

Breast:
- Shooting, stabbing or deep aching breast pain
- Breast pain typically occurs after feeding or expressing. The let-down reflex may be more painful than normal
- Breasts will appear normal. If inflamed, consider mastitis

Baby:
- White oral plaques
- Assume baby is colonised with thrush if mother has evidence of nipple thrush

91
Q

Management of lactose overload?

A
  • Block feeding (using one breast within a 4 hour period and then alternate to reduce the speed that the breast makes milk; usually only done for a few days) OR offering one breast at a time until empty: aim to down regulate milk production so infants receive more of the cream based milk at the end of the feed and stay fuller
  • Referral to lactation consultant
  • Refer to Australian Breastfeeding Association

92
Q

When to suspect lactose overload?

A
  • Unsettled
  • Adequate to large weight gains

A

Cream/fat that is usually found at the end of the breastmilk supply slows down the breastmilk transit through the gut to allow lactose to be broken down
