No ev that any non pharm therapies - acupuncture , homeopathy , salt mines , hypnosis work
doubling dose in exac does not work. Cochrane review shows that self management plans can reduced hosp admissions by half.
Seretide takes 20 min for onset and has flat dose response
Symbicort (budesonide+efometrol)works in 3 min and response increases with dose, can use extra when needed
when poorly use 2 puffs bd , when better ( after 1w when no blue and no night time waking) 1 bd and when worsening ( 2 bad days or 2 night time wakings ) 4bd-step down after 2 good days
oral steroids 7-10 fdays , 3-5 in chikldren

Chronic Kidney Disease

Diagnose and refer early . do eGFR - estimated gfr according to age sex and race, proteinuria acr/pcr , give previous u and e

Over 100-120 normal

Stage 2 less than 90
Stage 3 less than 60
Stage 4 less than 30
Stage 5 less than 15
Kidney disease is increasing due to nsaids , diabetes , hypertension, multsystem disease and ckd is itself a risk factor for heart disease


pbc - 95p per patient to set up business plan by cluster . Savings can be reinvested in patient care , if losses over three years pct can take budget back.

Books Gynae sims lateral speculum for prolapses Steady uterus with one or two fingers , feel uterus on abdo with left hand , left and right adenexa with right fingers for tenderness swabs endocerival for chlamydia and gonor , and entero uterine infections , behind cervix for candida and trichomonas etc.

us- 5 weeks gestational sac , 8w heart ,
hsg to outline tubes via cervix ; hysterocope to check fibroids , tumors ; laprascope for pelvic pain , sterilisation
