Study Notes
Dental Caries
- Untreated lesions can progress to pulp involvement, possibly causing an abscess.
- Tartar buildup can be observed at the base of teeth, alongside visible staining on crowns.
- Cavities require filling, typically with amalgam or composite materials.
- Prevention strategies include fluoride use to enhance tooth resistance, limiting dietary sucrose intake, and applying fissure sealants.
Periodontal Disease
- Affects over 80% of teenagers and adults, leading to significant tooth loss.
- Key symptoms involve gum inflammation and erosion of periodontal ligaments and supporting bone.
- Caused by various bacteria, including Streptococci and Porphyromonas.
- Gingivitis is the mildest form, progressing to periodontitis if untreated.
- Acute necrotizing ulcerative gingivitis (trench mouth) represents the most severe stage.
Rotavirus
- Significant contributor to infant morbidity and mortality, especially in developing countries.
- Accounts for one-third of childhood deaths in certain regions, primarily spread through the fecal-oral route.
- Main symptoms include watery diarrhea and vomiting within 48 hours.
- Treatment focuses on fluid replacement; prevention includes sanitary practices and vaccination with Rotateq.
Food Poisoning
- Diagnosis involves laboratory tests like PCR, stool culturing, and microscopic examination.
- For intoxications, treatment may not be necessary except for symptom relief and fluid replacement.
- Bismuth subsalicylate may alleviate diarrhea but should not be used if fever or blood in stools is present.
- Prevention tactics encompass cooking food thoroughly, avoiding cross-contamination, and practicing good hygiene.
Bacillary Dysentery (Shigellosis)
- Caused by various Shigella species, known for high infection rates and transmission through parenteral routes.
- Diagnosed via PCR testing; treatment includes peginterferon, ribavirin, and newer protease inhibitors.
- No vaccine available; condition is extremely infectious.
Hepatitis D and E
- Hepatitis D: Requires co-infection with Hepatitis B, leading to severe liver damage and higher mortality rates; diagnosed through IgM testing with no specific treatment available.
- Hepatitis E: Acquired via ingestion, presenting symptoms like those of Hepatitis A, with increased risk for pregnant women.
Mumps
- Caused by the mumps virus, transmitted through saliva and respiratory droplets.
- Initial replication occurs in the upper respiratory tract, followed by spread to the salivary glands.
- Symptoms include parotitis, headaches, malaise, and potential complications such as sterility and encephalitis.
- Prevented through vaccination with the MMR vaccine.
Ergot and Aflatoxin Poisoning
- Ergot Poisoning: Resulting from mycotoxins from Claviceps purpurea, affects grains, causing blood flow restriction and hallucinations.
- Aflatoxin Poisoning: Linked to Aspergillus flavus, primarily found in peanuts, can lead to liver cirrhosis and cancer.
Thrush (Oropharyngeal Candidiasis)
- Yeast infection caused by Candida albicans, affecting primarily newborns, children, and immunocompromised individuals.
- Symptoms include white patches, inflammation, and itching in the mouth.
- Diagnosis involves swabbing infected tissues; treated with oral antifungal agents like fluconazole.
Protozoan GI Diseases: Giardiasis
- Caused by Giardia lamblia, transmitted through contaminated water and food.
- Symptoms manifest as bowel inflammation, frothy diarrhea, and potential vitamin deficiencies.
- Diagnosis relies on stool appearance; treatment includes metronidazole and maintaining safe drinking water.
Amoebic Dysentery
- Triggered by Entamoeba histolytica, transmitted through fecal-oral routes via contaminated food or water.
- Symptoms range from mild abdominal pain to severe bloody stools and fever.
- Diagnosis includes stool samples; metronidazole is used for treatment, emphasizing the importance of water sanitation.
Cryptosporidiosis
- Characterized by severe watery diarrhea, caused by Cryptosporidium parvum.
- Management focuses on hydration and preventing outbreaks through sanitary practices.
