What is chronic meningitis? What is treatment of tubercular meningitis?

Introduction

Tuberculous Meningitis signs and symptoms:

1. Headache, malaise, mental confusion, and vomiting. 
2. Moderate increase in CSF cellularity, with mononuclear cells
3. Protein level is elevated, 
4. Glucose content reduced or normal. 
5. Well circumscribed intraparenchymal mass – tuberculoma.
6. Chronic tuberculous meningitis is a cause of arachnoid fibrosis, which may produce hydrocephalus.

Spirochetal infection of meninges:

Meningitis can Also be caused by different type of spirochetes Through the brain and the meninges.

Spirochetal Infections:

Neurosyphilis:

It can produce chronic meningitis (meningovascular neurosyphilis), usually involving the base of the brain, often with an obliterative endarteritis rich in plasma cells and lymphocytes.

Insidious progressive loss of mental and physical functions, mood alterations (including delusions of grandeur), severe dementia.  

Types of meningitis and their fingdings

Viral encephalitis causes, symptoms and management

Viral encephalitis is a parenchymal infection of the brain that is almost invariably associated with meningeal inflammation (better termed meningoencephalitis).

Causes of viral encephalitis:

1. Arbo virus
2. Herpes virus 
3. Rabies virus
4. Poliovirus
5. Cytomegalo virus
6. HIV virus

Cerebrospinal fluid (CSF) findings in different types of meningitis

Here’s a comparison table summarizing the cerebrospinal fluid (CSF) findings in different types of meningitis:

CSF Parameter	Bacterial Meningitis	Viral Meningitis	Tuberculous Meningitis	Fungal Meningitis
Opening Pressure	↑↑ (elevated)	Normal or slightly ↑	↑↑ (elevated)	↑ (elevated)
Appearance	Turbid or purulent	Clear	Clear or slightly cloudy	Clear or slightly cloudy
WBC Count	↑↑ (100–10000/mm³)	↑ (10–500/mm³)	↑ (100–500/mm³)	↑ (20–500/mm³)
Cell Type	Predominantly neutrophils	Predominantly lymphocytes	Lymphocytes	Lymphocytes
Protein	↑↑ (100–500 mg/dL)	Normal or mild ↑ (50–100 mg/dL)	↑↑ (100–500 mg/dL)	↑ (100–200 mg/dL)
Glucose	↓↓ (<40 mg/dL or <40% of serum)	Normal (>50% of serum)	↓ (<45 mg/dL)	↓ (low to normal)
Gram Stain	Positive in most cases	Negative	Negative	May show fungal elements (e.g. India ink for Cryptococcus)
Culture	Often positive	Usually negative	May be positive (Low yield)	May be positive
Other Tests	—	—	AFB stain, PCR, ADA ↑, TB culture	India ink, Cryptococcal antigen

Notes:

• In bacterial meningitis, neutrophilic predominance and very low glucose are classic.

• In viral meningitis, lymphocytic predominance with normal glucose helps differentiate it.

• TB meningitis and fungal meningitis often resemble each other, but TB typically has more pronounced protein elevation and low glucose.

• Always correlate CSF findings with clinical context and other investigations like imaging and cultures.

Differences between subarachnoid hemorrhage (SAH) and meningitis

Here’s a comparison table highlighting the differences between subarachnoid hemorrhage (SAH) and meningitis:

Feature	Subarachnoid Hemorrhage (SAH)	Meningitis
Cause	Ruptured cerebral aneurysm, AVM, trauma	Infection (bacterial, viral, fungal, TB)
Onset	Sudden (“thunderclap headache”)	Gradual or acute over hours to days
Headache	Severe, sudden, worst-ever headache	Gradual, diffuse headache
Fever	Usually absent or mild	Prominent feature, especially in bacterial meningitis
Neck Stiffness	Present	Present
Photophobia	Common	Common
Altered Consciousness	Common, especially with large bleed or raised ICP	May occur in severe cases
Seizures	May occur	May occur
Focal Neurological Deficits	May be present (due to vasospasm, infarct)	Less common; usually in complicated cases
CSF Appearance	Xanthochromia (after 12 hrs), bloody initially	Turbid in bacterial, clear in viral
CSF Opening Pressure	↑ (variable)	↑ in bacterial, TB, fungal; normal/mild ↑ in viral
CSF WBC	Mild ↑ or normal	↑↑ in infection (type depends on etiology)
CSF RBC	High in all tubes if SAH; clears if traumatic tap	Usually absent
CSF Protein	↑	↑↑ in bacterial/TB; mild ↑ in viral
CSF Glucose	Normal	↓ in bacterial/TB/fungal; normal in viral
Imaging	CT head: hyperdensity in subarachnoid space	CT/MRI may show meningeal enhancement
Treatment	Neurosurgical (clipping/coiling), supportive	Antibiotics/antivirals/antifungals depending on cause

Key Clinical Pearl:

• Both may present with headache and neck stiffness, but sudden onset without fever suggests SAH, while gradual onset with fever suggests meningitis.

MCQs on Breastfeeding For FCPS, NMC, MEC and FMGE

Understanding the biochemical and nutritional composition of breast milk is essential for taking the FCPS Part 1 exam, especially in Pediatrics and Physiology.

This post highlights some of the most frequently asked and controversial MCQs, along with explanations to help clear the concepts.

The post also highlights controversial and frequently repeated multiple-choice questions (MCQs) related to breast milk composition.

📌 1. Breast Milk is Deficient in Which of the Following?

Question:

Mother’s milk is deficient in?

Options:
A. Vitamin C ✓
B. Vitamin A
C. Casein
D. Lactalbumin
E. Pantothenic acid

Correct Answer: A. Vitamin C

Explanation:
While breast milk contains some amount of Vitamin C, it is generally lower compared to what is required for rapid growth in infants and also compared to certain formula or cow’s milk. Supplementation may be needed in some cases, especially if the mother is deficient herself.

📌 2. Comparison with Cow’s Milk – What’s Less in Mother’s Milk?

Question:

Mother’s milk is deficient in which of the following when compared to cow’s milk?

Options:
A. Vitamin C
B. Vitamin A
C. Casein ✓
D. Lactalbumin

Correct Answer: C. Casein

Explanation:
Casein is a major protein in cow’s milk, making it harder to digest. Mother’s milk contains less casein and more whey proteins like lactalbumin, making it gentler on an infant’s stomach. This is actually a benefit, not a deficiency, in terms of digestibility.

📌 3. What is Higher in Human Milk Compared to Cow’s Milk?

Question:

Mother’s milk has more of which of the following compared to cow’s milk?

Options:
A. Lactose ✓
B. Protein
C. Iron
D. Calcium

Correct Answer: A. Lactose

Explanation:
Human milk is rich in lactose, which aids in brain development and helps with calcium absorption. Cow’s milk, although higher in protein and calcium, contains less lactose.

📌 4. Which Immunoglobulin is Most Abundant in Breast Milk?

Question:

Which of the following immunoglobulins is more abundant in mother’s milk?

Options:

• IgG

• IgM

• IgA ✓

• IgE

Correct Answer: IgA

Explanation:
Secretory IgA is the dominant antibody in breast milk. It provides mucosal immunity, helping protect the baby’s gut and respiratory tract from pathogens.

📌 5. Which of the Following is Absent in Mother’s Milk?

Question:

Mother’s milk doesn’t contain:

Options:
A. Iron ✓
B. Casein
C. Lactalbumin

Correct Answer: A. Iron

Auxiliary Nurse Midwife (ANM) in Nepal: Past, Present, and Future

Introduction

The health system of Nepal has gone through massive transformations over the past few decades. One of the pivotal roles in improving healthcare delivery, especially in rural and underserved areas, has been played by Auxiliary Nurse Midwives (ANMs). These healthcare workers serve as the first point of contact for maternal and child health services in many parts of the country.

In this blog, we explore the past, present, and future of the ANM profession in Nepal and provide insights into courses and colleges that offer ANM programs.

The Past: Laying the Foundation

The Auxiliary Nurse Midwife profession in Nepal dates back to the 1960s and 70s, when maternal and child health (MCH) became a national priority. At that time:

• Nepal faced alarming rates of maternal and infant mortality.

• Health services were extremely limited in remote areas.

• The government, with support from international agencies, launched training programs to create a workforce of mid-level health professionals who could deliver basic services.

ANMs were primarily trained to:

• Conduct safe deliveries.

• Provide antenatal and postnatal care.

• Treat minor ailments.

• Offer family planning and immunization services.

These professionals were crucial, especially because doctors and nurses were rare in rural villages.

The Present: Expanding Roles and Responsibilities

Today, ANMs in Nepal are a cornerstone of the community health system. Their responsibilities have expanded significantly, including:

• Maternal, neonatal, and child health care.

• Family planning services and counseling.

• Immunization programs (especially EPI – Expanded Programme on Immunization).

• Nutrition education and health promotion.

• Basic emergency obstetric care in primary health care centers.

• Disease surveillance and health reporting at the community level.

• Community outreach and home visits.

ANMs now work in:

• Health Posts

• Primary Health Care Centers

• NGOs and INGOs

• Community Health Clinics

• Hospitals (in supportive roles)

The government’s National Health Policy recognizes ANMs as key players in achieving Universal Health Coverage (UHC) and Sustainable Development Goals (SDGs).

The Future: Challenges and Opportunities

The future of ANMs in Nepal looks promising, but it comes with challenges:

Opportunities:

• Advanced Training Programs: Upgrading from ANM to Staff Nurse (PCL Nursing) or Bachelor’s level nursing education.

• Greater Scope: Involvement in mental health, elderly care, and non-communicable diseases.

• Leadership Roles: Some ANMs are being trained to manage health posts.

• Digital Health Tools: Use of mobile apps and telemedicine to reach even more remote populations.

Challenges:

• Retention: Many trained ANMs leave rural postings due to lack of incentives and poor working conditions.

• Skill Gap: New diseases and health conditions require continuous training.

• Recognition: Many ANMs still struggle to get recognition for their work compared to higher-level health professionals.

With investments in capacity building, infrastructure, and professional development, ANMs can continue to be the backbone of Nepal’s healthcare system.

Colleges Offering ANM Courses in Nepal

Here are some notable institutes offering ANM courses:

Apart from these, many technical schools and community colleges across all provinces offer the ANM program to increase local accessibility.

Conclusion

Auxiliary Nurse Midwives have been — and will continue to be — vital in shaping Nepal’s public health system. From delivering babies in remote villages to helping fight national health emergencies, their contribution is immense.

With evolving healthcare needs, ANMs are expected to take on broader and more specialized roles. Supporting their education, career advancement, and working conditions is not just an investment in their future, but in the health of Nepal itself.

🚨 Erythema Migrans: The Early Sign of Lyme Disease! 🚨

Erythema migrans (EM) is the hallmark early sign of Lyme disease, a tick-borne illness caused by the bacterium Borrelia burgdorferi. Recognizing this distinctive rash is crucial for timely diagnosis and treatment, preventing the progression to more severe stages of the disease. (Lyme Disease: Symptoms, Treatment, Prevention & Recovery)

🦠 Cause: Borrelia burgdorferi (Tick-Borne)

Lyme disease is transmitted to humans through the bite of infected black-legged ticks, commonly known as deer ticks. These ticks are prevalent in wooded and grassy areas, particularly in the northeastern and north-central regions of the United States. The bacterium Borrelia burgdorferi resides in the tick’s gut and is transferred to humans during feeding. (What You Need to Know About the Stages of Lyme Disease)

🔴 Appearance: The “Bull’s-Eye” Rash

Erythema migrans typically manifests as a red, expanding rash that often exhibits central clearing, giving it a characteristic “bull’s-eye” or target-like appearance. However, the rash can vary in presentation: (Lyme disease. Borrelia burgdorferi infection – DermNet)

• Classic Bull’s-Eye: A red outer ring with central clearing.

• Uniformly Red Lesion: A solid red patch without central clearing.

• Multiple Lesions: In some cases, multiple EM rashes may appear, indicating disseminated infection.

The rash is usually not itchy or painful but may feel warm to the touch. It commonly appears at the site of the tick bite. (Lyme disease, [PDF] The Many Forms of Lyme Disease Rashes (Erythema Migrans) | CDC)

⏳ Timing: Appears 7–14 Days After a Tick Bite

Erythema migrans typically develops between 7 to 14 days after a tick bite, though the onset can range from 3 to 30 days. The rash expands gradually over several days and can reach up to 12 inches (30 cm) or more in diameter. Early recognition of EM is vital, as it allows for prompt treatment and reduces the risk of complications. ([PDF] The Many Forms of Lyme Disease Rashes (Erythema Migrans) | CDC, The Spectrum of Erythema Migrans in Early Lyme Disease)

⚕️ Treatment: Doxycycline or Amoxicillin

Early-stage Lyme disease, indicated by the presence of erythema migrans, is effectively treated with antibiotics. The choice of antibiotic depends on the patient’s age, pregnancy status, and other factors: (What You Need to Know About the Stages of Lyme Disease)

• Doxycycline: 100 mg twice daily for 10–21 days; not recommended for pregnant women or children under 8 years old.

• Amoxicillin: 500 mg three times daily for 14–21 days; suitable for pregnant women and young children.

Early treatment usually leads to a full recovery. Delays in treatment can result in the spread of the infection to joints, the heart, and the nervous system.

🧠 Additional Symptoms to Watch For

In addition to the rash, early Lyme disease may present with flu-like symptoms:

• Fever and chills

• Headache

• Fatigue

• Muscle and joint aches

• Swollen lymph nodes (Identifying Lyme Disease Rash From Pictures – Verywell Health)

If left untreated, the infection can progress to more severe stages, leading to complications such as arthritis, neurological disorders, and cardiac issues.

🛡️ Prevention Tips

Preventing tick bites is the most effective way to avoid Lyme disease: (Lyme disease)

• Wear long sleeves and pants when in wooded or grassy areas.

• Use insect repellents containing DEET on skin and permethrin on clothing.

• Perform thorough tick checks after outdoor activities.

• Shower soon after being outdoors to wash off unattached ticks.

• Promptly remove any attached ticks with fine-tipped tweezers.

📷 Visual Reference

For images illustrating the various presentations of erythema migrans, please refer to the Centers for Disease Control and Prevention (CDC) Lyme Disease Rashes page. These images provide valuable visual references to aid in the recognition of this early sign of Lyme disease. (Lyme Disease Rashes – CDC, The Spectrum of Erythema Migrans in Early Lyme Disease)

Early detection and treatment of erythema migrans are crucial in preventing the progression of Lyme disease. If you suspect a tick bite or notice a suspicious rash, consult a healthcare provider promptly.

Lek Lagnu: Understanding HAPE and HACE at High Altitudes

Lek Lagnu

Lek lagnu (लेक लाग्नु) is a common term in Nepali, referring to the life-threatening effects people can experience at high altitudes. While it can describe general altitude sickness, medically it often points to two severe conditions: High-Altitude Pulmonary Edema (HAPE) and High-Altitude Cerebral Edema (HACE). Both are emergencies that require immediate attention.

What is HAPE (High-Altitude Pulmonary Edema)?

HAPE is a condition where fluid collects in the lungs, making it extremely difficult to breathe. It usually occurs above 2,500 meters (8,200 feet), but it can happen at lower altitudes if a person ascends too quickly.

Symptoms of HAPE:

• Difficulty breathing, even while resting

• Severe coughing, sometimes with frothy or blood-tinged sputum

• Chest tightness or congestion

• Extreme fatigue and weakness

• Blue or gray lips and fingernails (due to lack of oxygen)

Why does HAPE happen?
At high altitudes, the lower oxygen pressure causes the blood vessels in the lungs to constrict. In some people, this leads to leakage of fluid into the air spaces of the lungs, making breathing almost impossible.

What is HACE (High-Altitude Cerebral Edema)?

HACE is even more serious and involves swelling of the brain due to lack of oxygen. It typically happens at altitudes above 3,000 meters (about 10,000 feet) but can occur lower if ascent is too rapid.

Symptoms of HACE:

• Severe headache that does not improve with painkillers

• Loss of coordination (walking unsteadily)

• Confusion, irritability, or hallucinations

• Drowsiness that can progress to unconsciousness

• Seizures in extreme cases

Why does HACE happen?
Reduced oxygen at high elevations causes brain blood vessels to leak fluid, leading to dangerous swelling inside the skull.

Key Differences between HAPE and HACE

How to Prevent Lek Lagnu (HAPE and HACE)

• Ascend slowly: No more than 300–500 meters per day once above 3,000 meters.

• Acclimatize properly: Rest every few days to adjust to the altitude.

• Stay hydrated: But avoid alcohol and sleeping pills.

• Recognize early symptoms: Never ignore headaches, breathing problems, or confusion at high altitude.

• Descend immediately: The best and fastest treatment for HAPE and HACE is to move to a lower altitude as quickly as possible.

• Oxygen and medication: Supplemental oxygen, and medicines like nifedipine (for HAPE) or dexamethasone (for HACE), can save lives if available.

Conclusion

Lek lagnu is not just a minor inconvenience; it can be deadly if it progresses to HAPE or HACE. Anyone trekking, climbing, or traveling to high-altitude areas like the Himalayas must be aware of the risks and take preventive measures seriously. Quick recognition, proper acclimatization, and immediate descent are the best defenses against these life-threatening conditions.
