Introduction

Diffuse connective tissue diseases include dermatomyositis, rheumatoid arthritis, systemic lupus erythematosus, etc. Dermatomyositis is an autoimmune disease affecting the skin and muscles. Rheumatoid arthritis is an autoimmune disorder primarily characterized by erosive arthritis, which can lead to joint deformities in severe cases. Systemic lupus erythematosus is a diffuse connective tissue disease with unclear etiology that can affect multiple organ systems throughout the body.

Diffuse connective tissue diseases include dermatomyositis, rheumatoid arthritis, systemic lupus erythematosus, and others. A detailed analysis is as follows:

1. Dermatomyositis

Dermatomyositis is an autoimmune disease affecting the skin and muscles. Causes include autoimmune factors, genetic predisposition, infections, and others. Common symptoms include edematous purplish-red rashes, poikiloderma, and symmetric muscle weakness. Treatment may include medications such as prednisone acetate tablets, methylprednisolone tablets, and betamethasone tablets, taken under medical supervision.

2. Rheumatoid Arthritis

Rheumatoid arthritis is a primarily erosive joint inflammatory autoimmune disease, with synovitis as its underlying pathology. In the early stages, symptoms such as morning stiffness, joint swelling, and pain occur. As the disease progresses, joint deformities may develop. Medications such as loxoprofen sodium sustained-release tablets, ibuprofen sustained-release capsules, and methotrexate tablets may be used under medical guidance.

3. Systemic Lupus Erythematosus

Systemic lupus erythematosus is a diffuse connective tissue disease of unclear etiology that can affect multiple organ systems throughout the body. Symptoms are complex and may include fever, rashes, and enlarged lymph nodes. Treatment under medical advice may involve medications such as aspirin tablets, prednisone acetate tablets, and hydroxychloroquine sulfate tablets.

In addition to the above conditions, other related diseases include Sjögren's syndrome.

Can a scratch from a small hamster cause disease?

In general, a minor hamster scratch may potentially cause disease, but illness does not always occur. Whether an infection develops mainly depends on whether the hamster carries pathogens and whether the wound is properly treated promptly after the injury. To reduce the risk, the wound should be immediately washed with soap and water and then disinfected with iodine tincture after a scratch. It is advisable to wear gloves when handling hamsters regularly, and the hamster's living environment should be cleaned routinely.

How many weeks should expectant fathers go for infectious disease screening?

The prospective father should undergo infectious disease screening 3–6 months before conception, including key tests for hepatitis B, hepatitis C, syphilis, and HIV. These screenings help detect infections early, prevent mother-to-child transmission during pregnancy, and protect the health of both mother and baby. If abnormal results are found, prompt medical consultation at a正规 hospital is necessary. Infectious disease screening during the preconception period is an essential step for achieving healthy pregnancy and optimal child development.

My mother-in-law has been diagnosed with Creutzfeldt-Jakob disease. Is this illness contagious to family members?

Creutzfeldt-Jakob disease is caused by prions and primarily spreads through contact with central nervous system tissues of infected individuals, such as brain or spinal cord tissue, or via contaminated medical instruments. The risk of infection during daily cohabitation—such as sharing utensils, casual conversation, or hugging—is extremely low if there is no contact with the patient's bodily fluids (e.g., blood, cerebrospinal fluid) or contaminated objects; therefore, excessive concern is unnecessary.

How soon can I get tested for the four major infectious diseases after being pricked by a used needle?

Some infectious diseases have a window period, during which a positive result cannot be detected immediately after infection. For example, the window period for HIV is typically 2–4 weeks, and for hepatitis B it is about 1–6 months. If testing is performed immediately after exposure, a false-negative result may occur due to the ongoing window period, making it impossible to accurately determine whether infection has occurred. Therefore, retesting after the window period is recommended as advised by a physician.

What is blood cancer?

Leukemia, commonly known as blood cancer, is a type of malignant tumor affecting the hematopoietic system. Its hallmark is uncontrolled abnormal proliferation of blood-forming cells in the bone marrow and other hematopoietic tissues, which subsequently impairs normal blood cell production. Diagnosis requires comprehensive evaluation including complete blood count and bone marrow aspiration. Treatment options include chemotherapy, targeted therapy, and hematopoietic stem cell transplantation. In daily life, emphasis should be placed on health protection and preventive measures.
