Syphilis is a sexually transmitted disease caused by the spirochete Treponema pallidum. It has four stages - primary, secondary, latent, and tertiary - and can cause lesions, rashes, and long-term damage if untreated. It is diagnosed through direct visualization of spirochetes or serological tests. Treatment involves penicillin, doxycycline, or tetracycline depending on the stage of disease. Syphilis can also be transmitted from mother to child during pregnancy or childbirth, potentially causing fetal death or lifelong infections.
Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. It has four stages - primary, secondary, latent, and tertiary.

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. It has four stages - primary, secondary, latent, and tertiary - and can also be transmitted from mother to fetus. Diagnosis involves tests to detect antibodies against T. pallidum such as RPR and TPPA. Treatment is with penicillin, though dose and duration varies by stage. Without treatment, later complications can include neurosyphilis, cardiovascular disease, and gummatous lesions. Ongoing research aims to develop vaccines and better understand disease progression and response to infection.

This document summarizes several bacterial STDs, including:
- Treponema pallidum, which causes syphilis. It is visualized via darkfield microscopy. Primary syphilis presents as a chancre and secondary syphilis has skin and mucous lesions.
- Haemophilus ducreyi causes chancroid presenting as genital ulcers with enlarged lymph nodes.
- Chlamydia trachomatis causes non-gonococcal urethritis and lymphogranuloma venereum.
- Neisseria gonorrhoeae causes gonorrhea presenting as urethral discharge and is diagnosed via gram stain of intracellular diplococci.
Syphilis is a chronic bacterial infection caused by the bacteria Treponema pallidum that is primarily transmitted through sexual contact. It progresses through three stages - primary, secondary, and tertiary - if left untreated. Primary syphilis involves skin sores, secondary syphilis involves rashes and mouth sores, and tertiary syphilis can damage internal organs. Syphilis is diagnosed through tests that detect antibodies produced in response to the infection. While antibiotics can cure it in its early stages, later stages may cause permanent damage without treatment.

Syphilis is a sexually transmitted disease caused by the bacterium Treponema pallidum. It has four stages: primary, secondary, latent, and tertiary. The primary stage involves a chancre at the infection site. Secondary syphilis causes a rash and mucous patches. Latent syphilis has no symptoms. Tertiary syphilis can cause gummas, neurological issues, and cardiovascular complications if left untreated. Syphilis is diagnosed through fluid microscopy, serological tests like RPR and FTA-ABS, and clinical history. It is treated with penicillin, doxycycline, or ceftriaxone depending on the stage. Prevention involves abstinence, condoms,
This document discusses sexually transmitted infections (STIs). It provides an overview of common STIs including bacterial STIs like syphilis, gonorrhea, chlamydia, and viral STIs like genital herpes and genital warts. It describes the causative agents, modes of transmission, symptoms, diagnoses and treatments for each STI. The document also discusses protozoan STIs like trichomoniasis. Overall, the document serves as an informative reference on the principal sexually transmitted infections, their characteristics, and clinical management.
Syndromic Approach to Sexually Transmitted Diseasesdralaaassan
STDs can present as different syndromes depending on the causative organism. Diseases presenting as genital ulcers include syphilis, herpes, chancroid, lymphogranuloma venereum, and granuloma inguinale. These differ in appearance, number of lesions, presence of pain or adenopathy, and systemic symptoms. Genital discharge is seen in gonorrhea and nongonococcal urethritis. Vaginal infections include bacterial vaginosis, candidiasis, and trichomoniasis. Pelvic inflammatory disease affects the upper genital tract and is usually caused by gonorrhea or chlamydia. Genital warts and molluscum cont
This document summarizes several herpesviruses that can cause infections in humans, including HSV, HZV, CMV, and EBV. HSV can cause oral and genital sores and remains latent in nerves. HZV, which causes shingles, results from reactivation of the varicella zoster virus. CMV is transmitted through bodily fluids and can cause severe disease in immunocompromised individuals. EBV commonly causes infectious mononucleosis and has been linked to some cancers.
This document summarizes information about spirochetes and Treponema pallidum, the bacterium that causes syphilis. It describes the morphology, culture characteristics, pathogenicity, stages of syphilis (primary, secondary, latent, tertiary), laboratory diagnosis, epidemiology, immunity, prophylaxis, and treatment of T. pallidum. Key points are that T. pallidum is a spiral-shaped bacterium that cannot be grown in culture but causes the sexually transmitted infection syphilis in humans, which progresses through distinct stages if left untreated and can be effectively treated with penicillin.

A blood culture test helps your doctor figure out if you have a kind of infection that is in your bloodstream and can affect your entire body. Doctors call this a systemic infection. The test checks a sample of your blood for bacteria or yeast that might be causing the infection.
Your doctor might order the test if you have symptoms that may include:
Fever or chills
Fatigue
Peeing less often than normal
Nausea
Confusion
Faster heart rate or breathing
If your infection is more severe, you might have:
Inflammation in different areas of your body
Small blood clots forming in your small blood vessels
A serious drop in your blood pressure
Organ failure
Mouthwash sampling Patients were asked to rinse and gargle 10 cc of normal saline (0.9%) for about 10–20 s and then spit the fluid into a sterile container.
In addition, other solutions were tested with a small number of patients, in order to compare it to the standard saline solution, which included the following:

The document provides an overview of the history, morphology, culture characteristics, epidemiology, pathogenesis, signs and symptoms, diagnostic tests, prophylaxis, and treatment for each stage of syphilis. Laboratory diagnosis involves darkfield microscopy, serological tests like VDRL and TPPA. Penicillin is usually used for treatment, while prevention involves condom use and testing of pregnant women.
This document provides an overview of lymphadenopathy in children, including its anatomy, pathophysiology, causes, and management approaches. It distinguishes between generalized and regional lymphadenopathy. Common causes of generalized lymphadenopathy include viral infections like mononucleosis, while regional lymphadenopathy is often due to infections in the local drainage area. Evaluation involves considering infectious, inflammatory, and malignant etiologies based on presentation. Management depends on the identified cause but typically involves supportive care or antibiotics for infections.

A 6-year-old boy presented with conjunctivitis of the right eye showing follicular hypertrophy and diffuse inflammation. Iodine staining of conjunctival scrapings revealed inclusion bodies of Chlamydia trachomatis, diagnosing trachoma. C. trachomatis is an obligate intracellular parasite that causes disease by direct destruction of infected cells and inducing inflammation. It enters through mucosal abrasions and replicates within epithelial cells, preventing lysosomal fusion. Repeated ocular infections contribute to trachoma pathology.
Lymphoma is a cancer that affects the lymphatic system, part of the body's immune system. It originates in lymphocytes and can be Hodgkin or non-Hodgkin lymphoma. Symptoms include enlarged lymph nodes, fever, weight loss, and fatigue. Diagnosis involves tests like biopsies and imaging. Treatment includes chemotherapy, radiation, immunotherapy, and targeted therapy, depending on the type and stage of the lymphoma. Early diagnosis and treatment can improve outcomes.

Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

9. Latent Syphilis:
It refers to positive syphilis serology with no evidence of clinical disease.
It is divided into two phases:
Early Latent Syphilis:•
No symptoms, positive serology within 2 years of infection• Patient is sexually
infectious.•
Late Latent Syphilis:
No symptoms, after 2 years of infection.
Patient is NOT sexually infectious.
10. Tertiary Syphilis;
occurs between 3 - 10 years after infection.
The characteristic feature is a chronic granulomatous lesion called a"gumma".,
The classic features are:
General paresis (dementia)
Cardiovascular findings (aortic root aneurysm, aorticregurgitation)

Pregnancy:Penicillin is the drug of choice
.Penicillin-allergic patients:-
Penicillin de-sensitization, followed by penicillin, OR Erythromycin for pregnant
woman and penicillin for newborn baby (to protect baby from syphilis as
erythromycin crosses placenta poorly)

29. HIV
Virology:•
HIV stands for human immunodeficiency virus.•
AIDS stands for acquired immunodeficiency syndrome.
• AIDS is caused by:• HIV-1.HIV is a single-stranded RNA retrovirus.
HIV belongs to Lentivirus group of retrovirus family.-
HIV-2.It causes less aggressive disease than HIV-1.- It is restricted mainly to western Africa.
Pathogenesis;
• The virus attaches to the surface of CD4 (Helper) T-cells.• The virus then enters the cell and uncoats, and its RNA
is transcribed toDNA by reverse transcriptase.The virus destroys CD4 T-cells and therefore weakens cell -
mediatedimmunity.Each day:> 1010 virions are produced i.e. daily turnover of 30% of total viralburden.> 10P CD4
T-cells are destroyed i.e. 6-7% of total body DA cells
.Mode of Transmission
:Sexual:Man-to-manHeterosexual (most common route accounting for > 75%)
Oral
Parenteral:
l:Blood (transmission risk is 90%)Injection drug users
Occupation injury
33. Vertical:
Vertical transmission
occurs during pregnancy, during birth, and breastfeeding
Vertical transmission is higher in developing countries (25-44%)than in industrialized countries (13-
25%).
80% of vertical transmission occurs during child birth(labour)20% of vertical transmission occurs in
utero.
Classification of HIV;
• HIV can be broadly classified into following types depending on clinical features:
o Primary infection Asymptomatic infection Mildly symptomatic infection Acquired immunodeficiency
syndrome (AIDS)
Primary Infection:Primary infection is symptomatic in 70-80% of cases.
Primary infection usually occurs 2 - 6 weeks after exposure.
Primary infection coincides with:High plasma HIV-RNA levelsFall in CD4 count to 300 - 400 cells/mm
,
34.
35. Clinical Features:
Fever with rash Pharyngitis with cervical lymphadenopathy Myalgias and arthralgias Headache and mucosal
ulceration
Asymptomatic Infection: It is category-A disease in Centers for Disease Control (CDC)Classification.
• The patient is seropositive, but no evidence of disease.
• The patient may have persistent generalized lymphadenopathy (PGL).•
PGL is defined as enlarged glands at 22 extra-inguinal sites.
• CD4 counts are normal (> 500/mm)CD4 count declines at a rate of 50 - 150 cells per year.
Mildly Symptomatic Disease:
• It is category-B
disease in Centers for Disease Control (CDC) Classification
36. Clinical Features:
presents with symptoms and diseases that are NOT AIDS definig illness,
such as:• Oral hairy leukoplakiaRecurrent
Oropharyngeal candidiasis- Recurrent vaginal candidiasis- Bacillary angiomatosis- Idiopathic thrombocytopenic
purpura Weight loss Herpes zoster Chronic diarrheaAIDS•
It is category-C disease in Centers for Disease Control (CDC)Classification
AIDS is defined by HIV with CD4 count < 200/mm?
or opportunisticinfections
or malignancy
38. Diagnosis:
• Best initial test= ELISA test.
o Confirmatory test = Western blot
Infected Infants : Diagnosed by PCR-RNA or viral culture
ELISA testing is unreliable because maternal HIV antibodies maybe present for up to 6 months
after delivery.
• Viral Load:
• PCR-RNA viral load test is used to Measure response to therapy (decreasing levels are good)
Detect treatment failure (increasing levels are bad)Diagnose HIV in infants
39. Treatment:
Indications for Treatment:
CD4 count and Indications for Treatment:- ≥ 350 cells/mm?:
Monitor 3 - 6 monthly
Consider treatment if hepatitis B or C co-infected or > 55years of age< 350
cell/mm3.- 350 - 200 cells/mm?
treat as soon as patient is ready< 200 cells/mm? = treat as soon as possible
Primary Infection is Indicator for Treatment
Start treatment if: There is neurologic involvementCD4 count is <200 cells/mm? for
> 3 months AIDS-defining disease
Choice of Drugs: Treatment of HIV is referred to as highly active retroviral
therapy(HAART).HAAR involves use of >3 drugs for better outcome and to
decrease resistance.
40. Regimen’s:
Regimen 1:
Two nucleoside reverse transcriptase inhibitors (NRTI), PLUS Non-nucleoside
reverse transcriptase inhibitor (NNRTI).
Example:Efavirenz + Tenofovir + Emtricitabine:
Regimen 2:• Two nucleoside reverse transcriptase inhibitors (NRTI), PLUS• Boosted
protease inhibitor (PI).
Example:Ritonavir - boosted Atazanavir + Tenofovir + Emtricitabine
Regimen 3:• Two nucleoside reverse transcriptase inhibitors (NRTI), PLUS• Integrase
Inhibitor (I), which inhibits final step of pro-viral DNAintegration
Example:Raltegravir (II) + Tenofovir + Emtricitabine
41. Treatment During Pregnancy;
All pregnant women should routinely be recommended for HIV testing.
The medications used are same as that for non-pregnant EXCEPT for Efavirenz,
which is contraindicated due its teratogenicity.
Therefore instead of Efavirenz a protease inhibitor should be used.
If mother is HIV positive and is already taking HAART then continue medications.
If mother is HIV positive with CD4 < 350 and HIGH viral load and is not on HAART:
Start treatment immediately Zidovudine + Lamivudine + Protease inhibitor
If mother is HIV positive with CD4 ≥ 350 and LOW viral load andis not on
HAART:Treatment is still required to reduce vertical transmission.
42. Anti-retrovirals between 2nd& 3rd trimester and stoppingafter birth.
Zidovudine monotherapy (starting from 12-14 weeks)
if viralload is low (<10,000 copies/mL) and Caesarean section is planned.
Other Measures to Reduce Vertical Transmission:Caesarean section if CD4 is low,
viral load is high, and patient not on HAART Caesarean section is not required if
patient is on HAART and viralload is low.
43. Avoid breastfeeding
Transmission rates:<1% = for Zidovudine monotherapy + Caesarean section<1% = for HART and
planned vaginal delivery
When viral load is <50 copies/ mL.
Post-exposure Prophylaxis : It is required for healthcare workers following occupational exposure to
HIV.
It is also required for non-occupation exposure (e.g. Victims of rape, sexual exposure)
British Recommendations :
Agents = Zidovudine + Lamivudine + Lopinavir/ Ritonavir, Duration =4 weeks
