38
Sx of VZV
- Flu like: increased temp | - Rash: cold- bubble - scab (including scalp and mucus membranes)
39
Dx of VZV
Serology and virus isolation
40
Complications of VZV
1. Bacterial skin inf (group A Strep, Staph aureus) 2. Encephalitis, meningitis 3. Pneumonia pneumonitis 4. Inflammation of the brain ans cerebellum 5. Keratitis and blindness 6. Death (imm.comp)
41
Tx of VZV
Antiviral drugs, acyclovir, valacyclovir or famcyclovir amy shorten the course of illness in pat >2yrs if stated within 24h of exanthem
42
Prevention of VZV
- Patient isolation - Vaccination: 12- 18 m w booster at 4- 6 y. Breakthrough inf can occur. Live attenuated virus are not given to imm.comp of pregnant pat.

45
Source of rubella
Sick man, droplet. Incubation 11-21d. Infective about 1 week before the rash and one week after the rash
46
sx of rubella
- Flu like symptoms w increased temp - Swollen LN in the neck and occipital area - Redness of the conjunctiva - Rash: delicate, pale pink, maculopapular, throat w Forsheimer spots (petechie)
47
Dx of rubella
Serological test and virus isolation
48
Complication of rubella
1. Thrombocytopenia 2. Arthritis 3. Encephalitis
49
Tx of rubella
symptomatic
50
Prevention of rubella
Isolation and vaccination, MMR 13-14 mc + 10y
51

53
Sx of measles
1. Incubation period, asymptomatic 3-5d 2. Usually mild fever, conjunctivitis and rhinitis, dry cough, Kopliks spots in mouth 3. Rash: increased fever up to 40C, maculopapular, malaise, rash starting at the forehead and moving down the body
54
Dx of measles
serology and virus isolation
55
Ddx of measles
other inf w rash, allergic reaction
56
complications of measles

57
Tx of measles
symptomatic
58
Prevention of measles
Isolation + vaccination MMR at 13-14 m + 10y
59
What causes Lyme disease
Borrelia burgdorferi through a bite from infected tick, mainly a nymph. Unlikely to transmit organism in early hrs of feed, but increasing risk w increased duration of the blood meal
60
Sx of Lyme
1. Fever, headache, fatigue 2. Rash: erythema migrans (60-80%) after 3-30d. Gradually expands peripherally over days. Not significantly raised or painful
61
dx of Lyme
- Not w erythema migrans! - Abs to B- burgdorferi are detectable within 4-8 w - Abs + DNA detection on CSF w suspected neuroborreliosis - DNA detection from skin biopsy when erythema migrants and acrodermatitis chronic atrophicans or testing synovial fluid in suspected lyme arthritis
62
tx of Lyme
- ABs: amoxicillin, sephalosporin, macrolides | - Early tx can prevent the risk of developing late stage complications
63
complications of lyme
1. Malaise 2. Neuroborreliosis: facial palsy, lymphocytic meningitis and radiculoneuritis (6-12w) 3. Arthritis, affects a large joint, most commonly the knee 4. Carditis, heart block
64
Prevention of Lyme
- Avoiding tick bite and early removal of attached ticks, protective clothing, tick repellants - Check skin periodically - Remove tick w fine-pointed forceps, grasp it as close as possible to the skin and gently upwards (trying not to break of the mouth part, risk is not increased if mouth part are left behind) - Skin disinfectant after, prevent pyogenic infection - Special attention to: groins, armpits, under breast, waist band area, backs of knees, head and neck
65
What is the role of the doctor and nurse in prevention of infection of children regarding vaccines
- Doctor: individualized advise, qualification for vaccine w history and physical examination - Nurse: administration and education
66
What are the contraindications for vaccine?
Absolute: 1) Severe systemic reaction after previous vaccine or substance in the vaccine 2) Admin of live vaccine in pat w impaired immune system 3) admin of live vaccine in pregnant women Special situation: risk of given clinical situation exceed benefit of vaccine
