Hookworm is caused by the nematodes Ancylostoma duodenale and Necator americanus. They penetrate the skin and migrate through the lungs before settling in the small intestine where they mature and lay eggs, causing a cyclic infection. Symptoms result from blood-feeding by the worms which causes anemia, and from larval migration which can cause skin lesions. Diagnosis is by finding characteristic eggs in stool samples under microscopy. Treatment involves anthelmintics to remove the worms along with iron supplementation for anemia. Prevention focuses on proper sanitation and avoiding barefoot contact with contaminated soil.
Candida albicans is a common fungal pathogen that normally lives in the human gastrointestinal tract. It can cause infections when there is an overgrowth, especially in immunocompromised individuals. C. albicans exists in both yeast and hyphal forms and is able to cause a variety of diseases depending on where in the body it infects, such as oropharyngeal candidiasis (oral thrush), vulvovaginal candidiasis (yeast infection), and invasive candidiasis. Transmission primarily occurs endogenously when there is a disruption to the normal microbiota. Treatment involves antifungal medications depending on the specific infection.
This document discusses yellow fever, a viral hemorrhagic disease transmitted by Aedes mosquitoes. It is caused by a flavivirus that primarily affects monkeys but can infect humans.

Hookworm is a parasitic nematode that infects the small intestine and is a major cause of iron-deficiency anemia globally. Two species infect humans - Ancylostoma duodenale and Necator americanus. The worms attach to the small intestine where the female lays thousands of eggs daily that are passed in feces. If soil contaminated with feces comes into contact with human skin, larvae can penetrate and migrate through tissues before reaching the intestine. This causes a rash and eosinophilia. In the intestine, the worms feed on blood, causing microcytic anemia. Over 900 million people are infected worldwide, especially in tropical areas with
Strongyloides stercoralis, also known as the dwarf threadworm or military worm, is a parasitic roundworm that infects the small intestine. It was first discovered in the feces of French soldiers in 1876. The parasite has a direct life cycle within the human host and an optional free-living cycle in the environment. Transmission occurs through skin contact with filariform larvae in soil. Light infections may be asymptomatic, while heavier infections can cause gastrointestinal or pulmonary symptoms. Diagnosis involves examining stool samples under a microscope or using concentration techniques to find rhabditiform larvae.

Infection occurs through contact with cat feces, contaminated food or water, or consumption of undercooked meat containing cysts. While most infections are asymptomatic, it can cause flu-like symptoms during acute phase or eye and brain damage in immunocompromised individuals. Treatment involves pyrimethamine, sulfonamides and spiramycine during pregnancy to reduce transmission to fetus. Prevention
The document summarizes the life cycle and transmission of malaria parasites. It discusses:
1) Malaria is caused by protozoan parasites of the genus Plasmodium, which are transmitted through the bites of infected Anopheles mosquitoes. The parasites have a complex life cycle involving both human and mosquito hosts.
2) In humans, the parasites initially infect and multiply in the liver before infecting and destroying red blood cells. Parasites developing in red blood cells cause the cyclical symptoms of malaria.
3) Mosquitoes can acquire the parasite by biting infected humans and ingesting sexual forms of the parasite. In the mosquito's gut the parasite undergoes further development before migrating
This document summarizes information about lymphatic filariasis, which is caused by infection with nematodes Wuchereria bancrofti and Brugia malayi. It affects over 120 million people globally. The life cycle involves transmission between humans and mosquitoes. Adult worms reside in human lymphatic vessels and nodes, producing microfilariae that circulate in blood mostly at night. This can lead to lymphadenitis, lymphangitis, lymphedema, and elephantiasis over time. Diagnosis involves detecting microfilariae or using immunological and molecular tests. Treatment is diethylcarbamazine to kill microfilariae and mosquito control to block transmission.
Yellow fever is caused by a flavivirus transmitted by Aedes aegypti mosquitoes. It occurs in tropical areas of Africa and South America, putting over 900 million people at risk.

Malaria is a protozoal disease caused by Plasmodium parasites and transmitted via mosquito bites. Symptoms include fever, chills, sweating and headaches in three stages. In 2020, there were an estimated 241 million malaria cases and 627,000 deaths worldwide. In India and West Bengal, reported cases decreased compared to 2019. Malaria is transmitted primarily by Anopheles mosquitoes and affects people differently based on age, sex, pregnancy status and socioeconomic factors. Diagnosis involves blood smear microscopy and treatment depends on the Plasmodium species and disease severity. Controlling malaria involves surveillance, vector control, early diagnosis and treatment, and health promotion.

Feeding plate for a newborn with Cleft Palate.pptxSatvikaPrasad
A feeding plate is a prosthetic device used for newborns with a cleft palate to assist in feeding and improve nutrition intake. From a prosthodontic perspective, this plate acts as a barrier between the oral and nasal cavities, facilitating effective sucking and swallowing by providing a more normal anatomical structure. It helps to prevent milk from entering the nasal passage, thereby reducing the risk of aspiration and enhancing the infant's ability to feed efficiently. The feeding plate also aids in the development of the oral muscles and can contribute to better growth and weight gain. Its custom fabrication and proper fitting by a prosthodontist are crucial for ensuring comfort and functionality, as well as for minimizing potential complications. Early intervention with a feeding plate can significantly improve the quality of life for both the infant and the parents.

2. Introduction
Measles is a highly contagious infection
caused by the measles virus (MeV).
The MeV is transmitted from person-to-
person via respiratory droplets or
aerosolized small particles suspended in the
air as a result of sneezing or coughing .
3. 1 out of every 1000 people with measles
will develop brain swelling leading to brain
damage.
Prior to the introduction of the measles
vaccine in the 1960s, measles was a leading
cause of childhood mortality, accounting for
2 million deaths globally each year.
4. Intro
The number of measles deaths decreased
drastically due to the initiation of the
Expanded Program on Immunization in 1974
and subseque
1to 3 out of 1000 people with measles will
die,even with best care.

5. Definition;
Measles is an acute highly contagious viral
disease caused by measles virus and it is
characterized by fever, URT catarrhal
inflammation, koplik’s spots and
maculopapules.
OR
It is an acute viral disease characterized by
rash maculopopular eruption and
catarrhal inflammation of the conjunctive
and of the aorta passages.
6.
7. Types of Measles
There are two types of measles which are;
Rubeola measles
Rubella measles
The rubeola virus causes "red
measles,"also known as "hard measles"or
just “measles."Although most people
recover without problems, rubeola can
lead to pneumonia or inflammation of the
brain (encephalitis).
8. The rubella virus causes "German
measles,"also known as "three-day
measles."This is usually a milder disease
than red measles. However, this virus can
cause significant birth defects if an infected
pregnant woman passes the virus to her
unborn child.
9. Cause of Measles
• It is caused by measles virus and it has been
classified as a paramyxovirus. Which is
spherical in appearance, measuring about
100~150nm in diameter. It has an outer
envelope composed of Mprotein, Hprotein,
Fprotein, and internal core is RNA.
10. Mode of spread
• Measles is spread through respiration
(contact with fluids from an infected
person's nose and mouth, either directly
or through aerosol transmission). And
therefore airborne precautions should be
taken for all suspected cases of measles.
11. INCUBATION
• The incubation period usually lasts for 4–12
days (during which there are no
symptoms). Infected people remain
contagious from the appearance of the first
symptoms until 3–5 days after the rash
appears.
12. Pathophysiology
The measles is a highly contagious air
borne pathogen which spreads primarily
via the respiratory system.The virus is
transmitted in respiratory secretions, and
can be passed from person to person via
aerosol droplets containing virus particles,
such as those produced by a coughing
patient.
13. Cont'd
Once transmission occurs, the virus infects
and replicates in the lymphatic system,
urinary tract, conjunctivae blood vessels
and central nervous system of its new
host.The role of epithelial cells is
uncertain,but the virus must infect them
to spread to a new individual.
14. Symptoms and Signs
Includes;
Fever
Runny nose
Cough
Red eyes (conjunctivitis)
A run-down or lethargic feeling
Loss of appetite
And a generalised, maculopapular,
erythematous rush.

Medical treatment
There is no specific treatment for measles.
Medical management is therefore
symptomatic.
• For fever administer analgesia e.g calpol
100mg to 200mg tds for 3 days.
19. • For conjunctivitis appropriate antibiotics
will be given such asTetracycline eye
ointment TDS.
• For itchy rash antihistamine e.g piriton
syrup or calamine lotion
• For cough safe cough remedies will be
given such as lemon tea, honey tea or
breast milk if breast fed.
• Antibiotic prophylaxis e.g Amoxycilline 125-
250mg TDS will be given
20. • Vitamin A supplementation for
preseevation of sight and also immune
booster will be given to the child. This will
be given 100000IU to 200000IU on day
1,2and day 8
• Sodium bicarbonate for mouth wash.
• Multivitamin will be administered to the
child.
22. Environment.
• Measles is highly infectious therefore the
child will be nursed in isolation and infection
prevention protocols should be applied, for
example wearing of protective clothing such
as gloves, gowns.
23. • Visitors will be restricted to prevent spread
of infection.
• The environment should be dim lit as the
patient may have photophobia due to
conjunctivitis. The room should be cool
and humid to prevent intense itchy from
rush.
24. Observations
• Vital signs especially temperature which is
usually high and swinging about 38C° 40C°
should be observed to see if it is increasing
or reducing.
25. • If temperature continues to be high
interventions for fever management will be
employed such as tepid sponging, cool
environment, and remove excess line and if
this does not workout the prescribed
antipyretic will be administered to the child
such as calpol.
• Temperature will be observed vigilantly in order
to identify and prevent complications because if it
is swinging it may denote setting in of
complications.
26. • The child will be observed for hydration because
he/she is losing a lot of fluids through diarrhea,
sweating, coughing and sneezing, therefore there
is need to ensure good hydration to avoid
dehydration.
• The skin will be observed for rash to see the extent
of rash and the parts that are affected. The mouth
of the child will be observed for koplik spots which
might hinder with sucking/feeding to see if it is
increasing or reducing.
27. Psychological care
• Explain the disease process in order to
raise the knowledge levels and thereby
alley anxiety Encourage the patient’s
mother to ask questions and answer
accordingly. Refer those can’t answer to
the physician Explain all procedures to the
patient in order to gain cooperation and
allay anxiety Involve a successfully managed
case to come and talk to the patient in order to
allow the patient ask pressing questions and
get answers.
28. • Involve the loved ones in the care in order
not to feel neglected.Provide diversional
therapy like toys, TV and radio in order to
shift the patient’s mind from the hospital
routine and the conditionExplain to the
mother/caretaker that the health care
team is doing everything possible to
ensure that the patient gets better in order
to promote co-operation
29. Hygiene
• Offer baths to the patient in order to
remove dead epithelium and promote
comfort. Do hair care to promote self
esteem and also prevent pediculosis. Do
nail care to prevent auto infection. Do
mouth care to prevent halitosis Any soiled
linen and clothes will be changed PRN to
promote comfort and prevent infection.
30. Elimination
• Provide a lot of fluids and roughage to
prevent constipation Provide copious fluids
in order to promote renal wash out and
thereby prevent renal problemsRecord fluid
intake and out put to prevent fluid
overload.
31. Nutrition
• Provide energy giving foods to provide the
energy needed for the metabolic processes.
Provide foods rich in protein like fish and
beans to promote replacement of worn out
tissues Vegetables and fruits will be provided
to raise the immunity and promote skin and
mucous membrane integrity.
32. Cont'd
• Provide a lot of oral fluids to prevent
dehydration due to excessive
sweatingServe small frequent meals to
promote appetiteDo regular mouth
washes in order to promote appetite.
Exercise
• Do passive exercises like limb movement
and massage in order to prevent muscle
atrophy and promote blood circulation
Encourage the patient to do deep
breathing exercises in order to promote
33. • Encourage early ambulation as soon as
the condition permits in order to prevent
deep vein thrombosis and other
complications of immobility
34. Position
• Patient will be put in fowlers position to
promote lung expansion and relieve
dyspneaChange the patient’s position two
hourly to prevent development of pressure
soresAs the condition improves, let the
patient adopt any position of comfort to
promote rest
35. IEC
• Educate on the condition in order to
create awareness and prevent recurrence
of the condition Explain the need for
taking the medication in order to promote
compliance.Educate about the signs and
symptoms of the condition for early
diagnosis and treatment thereby
preventing complications
36. • Talk to the patient about the need to take a
balanced diet using locally available foods
in order to boost the immunity.
• Advise the mother to avoid over crowded
areas and exposure of her child to out
breaks of measles to prevent occurrence of
the disease.Advise the mother to ensure
that child is vaccinated against Measles.
37. Preventive measures
• The most effective way to prevent measles
is through vaccination against the disease
• Isolate all cases of measles
• Prompt reporting and management of
measles
• Increased surveillance of the disease
38. Complications
• Otitis media, croup
laryngotracheabronchitis, pneumonia
surgical emphysema, empyema.
• Bronchopneumonia is single most usual
complication.
• Malnutrition due to anorexia, stomatitis
and diarrhoea Corneal uclers
39. • Bleeding due to thrombocytopnaenic
purpura, vascular damage
• Myocarditis which may progress to CCF.
• Febrile convulsions
• Acute encephalitis may occur.
• Mental retardation or epilepsy.
• Blindness
40. Summary
• Measles is a highly infectious disease
Remains one of the major causes of
morbidity and mortality in developing
nations, Major symptoms include fever,
cough,coryza, conjuctivitis and rash.
Measles has no specific treatment Best
preventive measure against disease is by
vaccination
