Rickettsiae are obligate intracellular bacteria that can cause diseases like Rocky Mountain spotted fever and typhus. They are transmitted through arthropod bites like ticks, mites and fleas. Common symptoms include fever, headache and rash. Diagnosis involves serologic tests detecting IgM and IgG antibodies. Doxycycline is the treatment of choice. Clinical features along with exposure history and serology can help diagnose rickettsial infections.
This document discusses myiasis, which is the infestation of human and animal tissues by fly larvae. It is classified as either obligatory, where the larvae develop inside the body, or facultative, where they develop in decaying flesh or wounds. Clinically, myiasis can affect the skin, nasal passages, eyes, ears, intestines or urogenital areas. Common causes include various blowfly, fleshfly, and botfly species. Symptoms depend on the type, but can include painful boils, creeping skin eruptions, or larvae visible in wounds or body openings. Treatment involves physically removing the larvae through extraction, irrigation, or medication in some cases.

This document provides information on viral exanthems, including goals of recognizing a morbilliform rash and describing presentations of childhood viral exanthems. It defines exanthem and enanthem rashes and describes morbilliform rashes as composed of erythematous macules and papules resembling measles. Classic childhood exanthems are described as measles, scarlet fever, rubella, roseola, and erythema infectiosum. Two case studies are presented - one involving a child with Koplik spots and a rash consistent with measles, and another involving an unvaccinated adult woman with a rash consistent with rubella.
Ticks and mites are external parasites that feed on blood and transmit diseases. Hard ticks remain attached while feeding, have a dorsal shield, and take several days to feed. Soft ticks leave after brief feedings. Scabies mites burrow under the skin and cause itching. Lice live on humans and transmit diseases. Cyclops are small crustaceans that act as intermediate hosts for diseases like Guinea worm. Controlling these parasites involves preventing contact, delousing with chemicals, boiling or filtering water, and engineering controls.

Signs and symptoms as well as treatments are provided for each condition. Risk factors for dry eye include age, sex, environment, medications, and underlying diseases. Diagnosis involves evaluating symptoms, tear production and stability tests, and ocular surface staining. Management focuses on treating underlying causes and supplementing tears through artificial tears or plugs/surgery.
2. Terminology
• Macule – flat lesion ,usually a circumscribed change of colour

1-Chicken-pox , Varicella zoster virus
2-Crops of vesicles mainly on the trunk and head.
-Pass through various stages of
papule, vesicle, pustule and crust.
3-Symptomatic :analgesia – paracetamol for
discomfort and pyrexia.
-pruritis – antihistamine or calamine lotion
- acyclovir only for those at risk of complications
or immunocompromised.

• 1-Impetigo
• 2-staph areus and streptococcal pyogenes
• 3-Thin–roofed vesicles or bullae surrounded by
narrow margin of erythema. The vesicles /bullae
rupture to release thin cloudy yellow fluid. This
fluid dries to form thick yellow crusts.
• 4-topical-bactroban(mupirocin)
ointment/betadine cream
- antibiotics – flucloxacillin or erythromycin

1-Kawasaki Disease, systemic vasculitis
2- Classical features of Kawasaki disease
• Fever lasting ≥5 days
• Marked irritability of the child
• Erythema, swelling and desquamation affecting the skin of the extremities
• Bilateral conjunctivitis
• Rash
• Inflammation of the lips, mouth and/or tongue
• Cervical lymphadenopathy

4 -Intravenous Immune Globulin 2g/kg x1
• Aspirin:
– 80-100 mg/kg/day until fever x 14 day, then
– 3-5mg/kg/day x ≥ 6-8 weeks
• echocardiograms

1-Scabies
2-Mite –sarcoptes scabeii
3 -Clothes, towels, and bed linen should be machine-washed (at 50
degrees Celsius or above) to prevent re-infestation and
transmission. Items that cannot be washed can be kept in plastic
bags for at least 72 hours to contain the mites until they die.
-benzyl benzoate lotion ,apply for 24hours ,may be repeated in 1 week
-permethrin cream
Antiscabial soap alone is not an effective treatment
Babies <2 months -5% sulphur ointment

1-Measles
2-single stranded RNA Morbillivirus from the paramyxovirus family.
3- Symptoms
• Prodrome - lasts 2-4 days with fever, runny nose, mild conjunctivitis and diarrhoea.
Koplik spots are pathognomic and appear on the buccal mucosa opposite the second
molar teeth as small, red spots each with a bluish-white speck (sometimes compared
to a grain of rice) in the centre.6 They occur in 60-70% of patients during the
prodrome and for up to 2-3 days before the onset of the rash.
• Rash - (morbilliform = measles-like) first seen on forehead and neck and
spreads, involves trunk and finally limbs over 3-4 days. It may become confluent in
some areas. Rash then fades after 3-4 days in the order of its appearance. It leaves
behind a brownish discoloration sometimes accompanied by fine desquamation.
4-Uncomplicated measles is usually self-limiting and treatment is mainly symptomatic
with paracetamol or ibuprofen and plenty of fluids. Patients should remain at home to
limit disease spread.
It is a notifyable disease
35. SLIDE 7
1- erythema infectiosum, slapped cheek disease, slapped cheek syndrome, fifth
disease, Parvovirus B19 (PV-B19), Sticker's disease
2- Parvovirus B19
3- After 3-7 days, the classic 'slapped cheek' rash appears as erythema on the
cheeks, sparing the nose, peri-oral and peri-orbital regions.6 This disappears after 2-
4 days.
• About 1-4 days after the facial rash appears, an erythematous macular/morbilliform
rash develops on the extremities, mainly on the extensor surfaces.7 It is usually not
itchy in young children, but may be itchy in older children and adults. This gradually
fades over the next 3-21 days, but may recur in reaction to various stimuli such as
exercise, heat and sunlight
4- It is usually mild and self-limiting in healthy people. It may also cause fetal loss or fetal
hydrops, reactive arthritis in adults, and severe anaemia in those with haematological
conditions or immunocompromise.Detection in pregnancy is important for monitoring
and possible treatment.

1-Miliaria
2-Miliaria is a common disorder of the eccrine sweat glands that often occurs in
conditions of increased heat and humidity. It is thought to be caused by blockage of
the sweat ducts, which results in the leakage of eccrine sweat into the epidermis or
dermis.
3-Two types
• -miliaria crystallina-clear superficial pinpoint vesicles
• -miliaria rubra –(prickly heat )-small discrete red papules,vesicles,papulovesicles
4-No compelling reason to treat miliaria crystallina exists because this condition is
asymptomatic and self-limited. he prevention and treatment of miliaria primarily
consists of controlling heat and humidity so that sweating is not stimulated. Measures
may involve treating a febrile illness; removing occlusive clothing; limiting activity;
providing air conditioning.
• Topical treatments that have been advocated involve lotions containing calamine
