Brian - Minamata Disease

Minamata Disease:

Minamata disease is a disorder caused by mercury poisoning that was first experienced by the inhabitants of Minamata Bay, Japan. This resulted from them eating fish contaminated with mercury industrial waste from a nearby factory. The disease is characterized by sense loss, tremors, dysarthria, ataxia, and both hearing and visual loss.
Even the unborn child is at risk from Minamata disease. Methyl mercury readily crosses the placenta from mother to fetus and is damaging, particularly to the developing brain. Children born with Minamata disease can have growth deficiency, microcephaly (an abnormally small head), severe mental problems and be deaf and blind.

Key Words Encountered:
Ataxia - Loses the ability to move the muscles
Acute Radiation Syndrome - All organs starts to die and eventually results in death
Dysarthisa - Muscle Problems which makes it hard to pronounce words
Mononucleosis 'The Kissing Disease' - Disease spread from kissing, creates numbness of mouth and trachea

Brian - Case Report - H1N1

Case Report:
Patient Name: Bobby Williams
Age: 28
Ethnicity: Caucasian
Gender: Male
History: Was around people who had the Influenza A (H1N1)
Temperature: 37.3 Degrees Celsius

Case Report:

A man aged 28 years with a history of sleeping disorder sought care at an emergency department on 28th January with a 3 day history of fever, chills, and cough. The patient reported he had been taking Paracetamol (Panadol) for a diagnosis of the flu, following complaints of body aches and dizziness, for the past 2 weeks. His vital signs showed a temperature of 37 degrees Celsius and heart rate of 84 beats per minute. Physical exam of the chest showed good air movement across the lungs, although chest scans later revealed a case of hardness to breathe.

The patient was admitted to the Intensive Care Unit (ICU) on antibiotics and required intubation on the second hospital day for worsening hypoxemia. Initial tests were negative against H1N1; the patient was started on a different type of antibiotics on his second day at the hospital. A repeat test of the patients showed positive for influenza A, with subsequent confirmation of influenza A (H1N1). The patient improved and was later extubated on hospital day 5, and was discharged on hospital day 10. He was feeling much better upon discharge but he still needed much rest until he was able to reach full strength.

Doctor In Charge: Brian Lay

Very well written Dr Lay :-)
Were your friends able to guess which disease the patient had?

Brian - Disease Studies

Disease Studies:
Bacteria:
  • Bacteria belong to the Kingdom Monera.
  • Their cells are very simple and their DNA is not contained within a nuclear membrane.
  • Bacterias dont have any type of particular shape so that means they could be round or boxy.
  • Bacteria has one of the fastest multiplying rates. If at body temperature multiplies every 20 - 30 minutes.
  • When Bacteria cell divdes it divides by mitosis and produces twno new bacteria.
  • Over a few days of growing the bacteria become quite large and the toxins in the bacteria starts to disrupt the body.
  • Bacterias are tiny as they can only be seen other the microscope
  • Bacteria are present in most habitats on Earth, growing in soil, acidic hot springs, radioactive waste, water, and deep in the Earth's crust.
  • Baceteria are also present inorganic matter and the live bodies of plants and animals, providing outstanding examples of mutualism in the digestive tracts of humans, termites and cockroaches



Viruses:
  • Viruses are not classified into the major kingdoms of living organism as they are not celluar life forms
  • Viruses consist of particles that are usually made up of bundles of genetic material inside a protein coat
  • Viruses invade the host and use the nucleus of the host to complete the repoduction
  • The orignal virus cell will die and split open thousands of new viral particle which will then infect other cells
  • Viruses are tiny ast they cna only be seen under the microscope
  • Viruses can be carried by blood sucking insects or animals



Protozoans:
  • Protozoans are mostly multicelluar organisms.
  • Protozoans are singled celled microbes with their DNA inside a nucleus
  • Protozoans vary widely in shape and they mainly live in water or very moist soil
  • Protozoans can be seen with be barely seen with human eyes as they are roughly around 1mm wide

Fungi:
  • Fungi are most multicelluar organisms
  • Fungi are part of the Fungal Kingdom and its is distinct from plants.
  • The reason being for Fungi to be distinct from plants is that they do not produce their own food by photosynthesis
  • The parisitic fungi reproduce sexually or asexually
  • Fungi are abundant in soil and therefore comes in human contact frequntly
  • Contact with human will spread diseases around the skin, hair or nails
  • Mushrooms are a type of fungi which are safe for human consumption
  • Fungi can be eaasily seen with the human eye as there are roughly 1 cm wide

Name of the disease:
  • Tuberculosisnis - Bacterial
Background information of the Bacteria disease:
  • Bacteria belong to the Kingdom Monera.
  • Their cells are very simple and their DNA is not contained within a nuclear membrane.
  • Bacterias dont have any type of particular shape so that means they could be round or boxy.
  • Bacteria has one of the fastest multiplying rates. If at body temperature multiplies every 20 - 30 minutes.
  • When Bacteria cell divdes it divides by mitosis and produces twno new bacteria.
  • Over a few days of growing the bacteria become quite large and the toxins in the bacteria starts to disrupt the body.
  • Bacterias are tiny as they can only be seen other the microscope
  • Bacteria are present in most habitats on Earth, growing in soil, acidic hot springs, radioactive waste, water, and deep in the Earth's crust.
  • Baceteria are also present inorganic matter and the live bodies of plants and animals, providing outstanding examples of mutualism in the digestive tracts of humans, termites and cockroaches
Cause:
  • The causes of tuberculosisnis are caused by a sever case of bacteria. This bacteria primarilly attacks the lungs but it also has secondary attack points for example the other parts of the body such as the kidney, spine, and brain.
Incidence:
  • 137 cases per 100,000 people
Risk factors:
  • Alcoholism
  • Drug abuse
  • Crowded living conditions
  • Homelessness
  • Poverty
  • Immigration from certain countries
  • Very Low Body Weight
  • Certain medical treatments such as organ transplant
Symptoms (diagnosis):
  • Persistent Coughing
  • Chest Pain
  • Loss of Apetite
  • Lost of Weight
  • Fatigue
  • Weakness
  • Fever and the Flu

Treatment (or management of patient, eg if it’s terminal):
  • Antibiotics
  • Surgery
  • Drugs
  • Steroids
‍Control (government, handwashing, isolation, infectious disease ward – of the disease, the person who is sick):
  • Covering you mouth when your coughing or sneezing
  • Stay up to date with you immunization schedule
  • Finish the entire course of medication

Prognosis:
  • If you get TBN you will have to finish the medication but if you dont it will result in death

Very well done Brian, you have identified all the factors correctly for this disease.
Your wiki page is off to an excellent start - well done.
Please add your Malaria One World practice task here also, you showed really good understanding of the various viewpoints in our class discussion.
Well done,
Mrs S
