Neurofibromatosis

Neurofibromatosis 1

Neurofibromatosis 2

NF1 tumor suppresor gene Mutation located on chromosome 17, encodes for neurofibromin

NF2 tumor suppresor gene Mutation located on chromosome 22, encodes for merlin

clinical features: Cafe-au-lait spots, multiple neurofibromas and lisch nodules

Clinical features: bilateral acoustic neuromas

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.
