Deep Vein Thrombosis: Invasive Treatment & Natriuretic Peptide Tests
Indications for Invasive Treatment of Deep Vein Thrombosis
- Phlegmasia
- Symptoms of IVC thrombosis
- Acute iliofemoral DVT
- Insert IV line into a vein
- Anesthesia is injected
- A small incision is made
- Guided X-ray, insert catheter via skin
- Contrast media injected
- X-ray is taken to find clot location
- Clot-dissolving drugs are given
- Catheter removed, pressure to stop bleeding
- Dressing is put on
- Daily examination of calves
- Anticoagulants
- Stay hydrated
- Bed rest
- Foot elevation
B-type Natriuretic Peptide
Bacterial Culture, Diseases, and Biotechnology Uses
Bacterial Culture Media, Mutation, and Strain
Bacteria can grow in artificial culture media, which serve to isolate and identify them. There are two types of culture media:
- Solid: Contains water, sodium chloride, proteins, and a solidifying substance called agar. The advantage of solid media is that it allows us to distinguish different bacterial colonies.
- Liquid: Contains water, sodium chloride, and proteins. In liquid media, bacteria grow uniformly.
Mutation and Strain: A mutation is an alteration

Sterilization vs. Disinfection
- Sterilization: Complete eradication of all viable microorganisms, including bacteria, viruses, fungi, and spores. Methods include:
- Autoclaving (high pressure and temperature)
- Pasteurization (moderate heat)
- Cold methods (refrigeration and freezing)
- Filtration
Sexually Transmitted Infections: Symptoms, Diagnosis, and Treatment
Sexually Transmitted Infections
Syphilis
Syphilis is caused by the spirochete bacterium. It spreads through sexual contact, placental transfer, and blood. Symptoms include a painless but highly contagious sore or ulcer on the genitals, and swollen lymph nodes in the groin. Advanced stages can manifest as skin problems, hepatitis, nervous system issues, or bone problems. Diagnosis is through the VDRL test. Treatment involves penicillin injections. Untreated syphilis can lead to heart and central nervous
Bacterial, Viral, and Foodborne Illnesses: Symptoms and Treatment
Bacterial Infections
Borrelia burgdorferi (Lyme Disease)
- Disease: Lyme Disease
- Vector: Ticks (commonly found in deer habitats)
- Symptoms: “Bull’s-eye” rash, flu-like symptoms, heart inflammation, neurological abnormalities, arthritis
- Diagnosis: PCR DNA test, ELISA, Western Blot for IgM/IgG antibodies
- Treatment: Amoxicillin, tetracycline
- Prevention: Destroy tick habitats, use insecticides, tick repellents (e.g., DEET), inspect skin, and promptly remove ticks (within 24 hours)
Helicobacter pylori

Disease Outbreaks: Definitions, Steps, and Modes of Transmission
Disease Detectives
Pandemic: A global disease outbreak.
Outbreak: A sudden occurrence of disease in a community.
Epidemic: A widespread occurrence of a disease in a community at a particular time.
10 Steps to Investigate an Outbreak
- Prepare for field work
- Establish the existence of an outbreak
- Verify the diagnosis
- Construct a working case definition
- Find cases systematically and record information
- Develop Hypothesis
- Evaluate hypotheses
- Refine
