Features of Wenicke-Korsakoff Syndrome
Associated conditions
  • Chronic alcoholism (most common).
  • Malnutrition.
Pathophysiology Thiamine deficiency impairs ATP generation leading to neuronal dysfunction and death. It mostly has paraventricular lesions involving mammillary bodies and dorsomedial bodies.
Clinical findings
  • Confusion.
  • Oculomotor dysfunction (horizontal nystagmus and bilateral abducens palsy)
  • Postural and gait ataxia.
  • Memory impairment (permanent).
Treatment
  • Intravenous thiamine.
  • Administration of glucose before the thiamine can worsen the symptoms.
Acne vulgaris
Clinical features
  • Comedonal acne:Closed or open comedones on forehead, nose and chin.
  • Inflammatory acne: Small, erythematous papules and pustules.
  • Nodular acne: Large painful nodules; sinus tracts and scarring.
Pathogenesis
  • Hyperkeratinization and obstruction of the pilosebacous follicles.
  • Sebaceous gland enlargement and increased sebum production.
  • Metabolism of sebaceous lipids by Cutibacterium acnes and release of inflammatory fatty acid.
  • Follicular inflammation and rupture,
Risk factors i) Increased circulating androgen (e.g. PCOS, puberty)

ii) Mechanical trauma/friction (excessive scrubbing, tight clothing)

iii) Comedogenic oil based skin and hair products.

iv) Excessive heat.

v) Obesity

Criteria for the diagnosis of SLE
Clinical features Characteristics
1)Malar rash Fixed erythema, flat or raised, sparing the nasolabial folds
2)Discoid rash Erythematous raised patches with adherent keratotic scarring and follicular plugging.
3)Photosensitivity Rash due to unusual reaction to sunlight.
4)Oral ulcer Oral or nasopharyngeal ulcers, which may be painless.
5)Arthritis Non-erosive arthritis, involving >2 peripheral joints.
6)Serositis Pleuritis or pericarditis
7)Renal disorder Persistent proteinura ( >0.5g/24hrs) or cellular casts (red cell, granular or tubular).
8)Neurological disorder Seizure or psychosis, in the absence of provoking drugs or metabolic derangement.
9)Hematological disorder Haemolytic anemia or leucopenia (<4 x109) or lymphopenia (<1x109) or thrombocytopenia (<100x109) in the absence of offending drugs.
10)Immunological Abnormal titre of Anti-DNA antibodies or presence of Sm antigen or positive antiphospholipid antibodies.
11)Anti-nuclear Antibody (ANA) Abnormal ANA titre measured by immunofluorescence
Diagnosis of SLE is made in an adult if 4 out of 11 features are present either serially or simultaneously.
  • Erythematous raised patches with adherent keratotic scarring and follicular plugging.
