left sided pneumothorax


PNEUMOTHORAX

Pneumothorax is the presence of air in the pleural space.

Two types

  • Traumatic pneumothorax
  • Spontaneous pneumothorax
Traumatic pneumothorax 
  • Results from penetrating or non-penetrating chest injuries.
Iatrogenic
  • Transthoracic needle aspiration
  • Thoracentesis
  • The insertion of central intravenous catheters
Spontaneous 

  • Primary Pneumothorax

  1. No evidence of overt lung disease.
  2. Due to rupture of a small subpleural emphysematous bulla or pleural bleb, or the pulmonary end of a pleural adhesion
  3. Occur almost exclusively in smokers
  4. one-half of patients will have a recurrence

  • Secondary Pneumothorax

  1. Underlying lung disease, most commonly COPD and TB;
  2. also seen in asthma, lung abscess, pulmonary infarcts, bronchogenic carcinoma, all forms of fibrotic and cystic lung disease

Tension pneumothorax

  • Results from a wound in the chest wall which acts as a valve that permits air to enter the pleural cavity but prevents its escape
  • Intrapleural pressure rises to well above atmospheric levels. 
  • The pressure causes mediastinal displacement towards the opposite side, with compression of the opposite normal lung 
  • Impairment of systemic venous return, causing cardiovascular compromise

Closed pneumothorax

  • Communication between the airway and the pleural space seals off
  • mean pleural pressure remains negative
  • reabsorption of air, re-expansion, infection is uncommon

Open pneumothorax

  • Communication fails to seal and air continues to pass freely
  • Occur following rupture of an emphysematous bulla, tuberculous cavity or lung abscess into the pleural space
  • Infection is common

Clinical Features of tension pneumothorax

  • sudden-onset unilateral pleuritic chest pain or breathlessness
  • larger pneumothorax (> 15% of the hemithorax) results in decreased or absent breath sounds
  • combination of absent breath sounds and resonant percussion note is diagnostic of pneumothorax.

  • Inspection

    • Tachypnoea (pain, deflation reflex)

  • Palpation

    • ↓Expansion

  • Percussion

    • Resonant or hyper-resonant

  • Auscultation

    • Absent breath sounds

Tension pneumothorax also causes

  • Deviation of trachea to opposite side
  • Tachycardia and hypotension
  • Cyanosis 

Investigations for pneumothorax

  • Chest X-ray

    • Sharply defined edge of the deflated lung with complete translucency
    • Extent of any mediastinal displacement and reveal any pleural fluid or underlying pulmonary disease.

  • CT scan
    •  In doubt, distinguish bullae from pleural air.

Treatment of tension pneumothorax

  • Primary pneumothorax with lung edge < 2 cm from the chest wall, not breathless requires no intervention.

Percutaneous needle aspiration of air 

  • In young patients with a moderate or large spontaneous primary pneumothorax
  • Intercostal tube drainage
  • In those over 50 years old and those with respiratory compromise

Surgical pleurodesis 

  • Recommended following a second pneumothorax
  • should be considered following the first episode of secondary pneumothorax if low respiratory reserve makes recurrence hazardous. 
  • Pleurodesis can be achieved by pleural abrasion or parietal pleurectomy at thoracotomy or thoracoscopy.
  • Prevents recurrences

Post Chest Tube monitoring: what to look for after keeping a chest tube

  • After 24 hours;  if lungs reinflated and no bubblingremove drain
  • Continuing bubbling after 5- 7days  is indication of surgery
  • High flow O2 supplement- may speed resolution
  • If bubbling stops before full inflation of lung then tube is either blocked , kinked or displaced
  • Pleural Effusion 

Pleural effusion:

Pleural Fluid

  • Excessive accumulation of fluid in the pleural space. 
  • Detected clinically, when ≥ 500 mL is present.
  • Produced and absorbed at a rate of 15mL per day
  • Each pleural space contains 10mL of fluid

The estimated prevalence of pleural effusion is 320 cases per 100,000 people.

Causes of pleural effusion:

Pathophysiology of pleural effusion:

Fluid enters the pleural space:

  • from the capillaries in the parietal pleura
  • from the peritoneal cavity via small holes in the diaphragm
  • Fluid removed via the lymphatics situated in the parietal pleura. 

lymphatics have capacity to absorb 20 times more fluid than is normally formed.

Pleural fluid accumulates when:

pleural fluid formation >pleural fluid absorption. 

Exudative or Transudative

Alteration of hydrostatic and/or oncotic factors Increases the formation or decreases the reabsorption Transudate

Direct or cytokine induced pleural membrane and/or vascular damage Increased capillary permeability Exudate

Types of pleural effusion:

Transudative effusion

  1. Congestive Heart failure
  2. Cirrhosis 
  3. Pulmonary embolization 
  4. Neoplastic syndrome
  5. Constrictive pericarditis
  6. Hypothyroidism

Exudative effusion:

  1. Bacterial pneumonia (common)
  2. Tuberculosis
  3. Carcinoma of the bronchus
  4. Pulmonary infarction
  5. Autoimmune 
  6. -Rheumatic diseases
  7. – SLE 

Clinical features of pleural effuion:

  • Shortness of breath
  • Chest pain, especially on breathing in deeply (pleurisy, or pleuritic pain)
  • Fever
  • Cough

How Patient Presents in pleural effusion?

History in pleural effusion

  • Pain on inspiration and coughing
  • Often  asymptomatic
  • Pleurisy 

Examination finding in pleural effusion:

  1. Chest wall movement : Reduced in affected side 
  2. trachea and mediastinum shift away from affected side
  3.  With massive effusion (>1000ml)]
  4. Percussion note: Stony dull 
  5. Breath sounds: Vesicular
  6. (Reduced or absent)
  7. Vocal resonance: Reduced or absent

On Chest Examination of pleural effusion following findings  can be found:

  • Bronchial breathing may be present
  • Expansion ↓
  • Percussion stony dull
  • Air entry ↓
  • Vocal resonance ↓
  • With massive effusion (>1000ml) trachea and mediastinum shift away from affected side

Diagnostic Approach in pleural effusion

Light’s criteria for Exudative Effusion

  • Pleural fluid protein: serum protein >0.5
  • Pleural fluid LDH: serum LDH >0.6
  • Pleural fluid LDH > 2/3 upper limit of normal for serum
  • Investigations 
  • Serum
  • CBC
  • LDH
  • protein
  • Coagulation studies (PT, PTT, INR )

Pleural fluid analysis for pleural effusion:

  • Note color and consistency
  • Chemistries: Protein, albumin, LDH, glucose, pH
  • Cell count with differential
  • Microbiological stains and culture 
  • Cytology

Pleural fluid finding in effusion

Lateral decubitus x ray in pleural effusion:

  • Demonstrates fluidity
  • Suggest for thoracentesis if fluid layer > 1cm. 
  • Transudates
  • Usually resolve with treatment of underlying cause
  • Therapeutic thoracentesis in persistent larger effusion
  • Pleurodesis, shunts, or placement of a indwelling pleural catheter for palliation

Treatment of pleural effuusion:

  • Simple Parapneumonic Effusion

    • Antiobiotics
    • Selected base on causing organism
    • Generally anaerobic coverage
    •   ( clindamycine, imipenem, extended spectrum penicillin )
    • Close observation
  • Complicated Parapneumonic Effusion
    • Antiobiotics
    • Early thoracostomy tube drainage
    • Surgical decortication if extensive pleural thickening, fibrous organization, and /or multiple loculations.
    • Malignant Pleural Effusion
    • 2nd most common type of exudative pleural effusion (lung carcinoma, breast carcinoma, & lymphoma)
    • Diagnosis: cytology of the pleural fluid
    • If cytology is negative, thoracoscopy is done if malignancy is suspected

Management  of pleural effusion

  • Symptomatic treatment 
  • Tube thoracostomy ( sclerosing agents : doxycycline )
  • Plurodesis when there is rapid reaccumulation of fluid
  • Insertion of indwelling pleural catheter

Complications of pleural effsuion if untreated

  1. empyema
  2. constrictive fibrosis
  3. Sepsis
  4.  lung cancer

Nursing care for pleural effusion and chest tube inserted patient

  • Observe for infection, local inflammation
  • Check dressing
  • Check if tube is blocked
  • Mobilization care
  • Check for amount and color of drainage
  • Pain management
  • Ensure breathing and lung reexpansion in case of collapse
  • Prevent clamping
  • Ensure positioning

Introduction

Smoking and alcohol use are two of the most prevalent and dangerous health risks in the world today. Both habits can have a devastating impact on a person’s physical and mental health, leading to a wide range of diseases and conditions that can be life-threatening.

The Harms of Smoking

There are several harms of smoking that include personal, health, family , social and nation wise harms. It not only harms teh user but also the whole bnation and the global effect is there.

Effect of smoking

Cigarette smoking is a leading cause of preventable death worldwide. Smoking can cause a wide range of health problems, including lung cancer, heart disease, stroke, and chronic obstructive pulmonary disease (COPD). Smoking also affects the reproductive system, leading to fertility issues in both men and women. It can also harm unborn babies, causing low birth weight and a range of other problems.

No Smoking

Smoking and lung cancer

One of the most significant risks of smoking is lung cancer. According to the American Lung Association, smoking causes 85% of lung cancer cases in the United States. In addition to lung cancer, smoking can also cause other types of cancer, including throat, bladder, and pancreatic cancer. Smoking can also lead to emphysema, a condition in which the air sacs in the lungs are damaged, making it difficult to breathe.

Cardiovascular risks of smoking

Smoking also damages the cardiovascular system, increasing the risk of heart attack and stroke. Nicotine in tobacco smoke raises blood pressure and heart rate, while carbon monoxide reduces the amount of oxygen that can be carried in the blood, making it more difficult for the heart to pump blood.
The Harms of Alcohol Use

Alcohol use is also a significant health risk, particularly when consumed in excess. Alcohol consumption can cause liver disease, pancreatitis, and a range of other health problems. Chronic alcohol use can also lead to high blood pressure, heart disease, and stroke.

Excessive alcohol use can also lead to alcoholism, a condition in which a person becomes physically and psychologically dependent on alcohol. Alcoholism can lead to a range of problems, including social isolation, relationship issues, and financial difficulties.

Alcohol drinks

Physical health risks of smoking

In addition to the physical health risks, alcohol use can also have a significant impact on mental health. Alcohol use can increase the risk of depression and anxiety, and it can also lead to other mental health problems, such as bipolar disorder.

No smoking sign

Conclusion

Beer in a glass

Smoking and alcohol use are two of the most significant health risks facing people today. Both habits can have a devastating impact on a person’s physical and mental health, leading to a wide range of diseases and conditions that can be life-threatening. If you smoke or drink alcohol, it is important to take steps to quit or reduce your use. Talk to your healthcare provider for guidance and support on quitting smoking and cutting back on alcohol use. Your health and well-being are too important to risk.

Comprehensive Abortion Care in Nepal 2024

What is Comprehensive Abortion Care?

Table of Contents(toc)

Introduction

Comprehensive Abortion Care (CAC) is a patient-centered, comprehensive approach to abortion that includes services ranging from counseling and medical procedures to post-abortion care and support. It prioritizes women’s health, safety, and well-being while protecting their reproductive rights. CAC addresses not only the medical elements of abortion, but also the social, emotional, and psychological issues that influence a woman’s decision-making process. This article discusses the significance of comprehensive abortion treatment and its components.

Understanding Comprehensive Abortion Care

Abortion Care that is Comprehensive goes beyond the typical focus on medical procedures. It recognizes that women’s needs and experiences vary, and that these must be taken into account while providing abortion services. CAC’s basic components are as follows:

Safe and Legal Abortion Services:

CAC guarantees that women have safe and legal abortion methods available to them. Abortions are performed in a clinical setting by qualified healthcare professionals in accordance with medical standards and guidelines. Legal frameworks must protect women’s right to choose abortion without fear of legal prosecution.

Pre-Abortion Counseling:

Proper counseling is crucial to ensure that women make informed decisions about their reproductive health. It involves providing accurate information about abortion methods, potential risks, and available support services. Counseling also addresses emotional and psychological concerns, helping women feel confident in their choices.

Medical Procedures:

Proper counseling is essential to ensuring that women make educated reproductive health decisions. It entails disseminating correct information regarding abortion methods, dangers, and available support services. Counseling also tackles emotional and psychological issues, allowing women to feel more confidence in their decisions.

Post-Abortion Care:

Comprehensive care goes beyond the actual abortion. Follow-up consultations to check on physical healing and treat any issues are part of post-abortion care. To assist women in overcoming any potential emotional difficulties, counseling and emotional support are also available.

Contraceptive Services:

Access to contraceptive advice and services is a component of CAC in order to avoid future unwanted pregnancies. Based on their health, lifestyle, and reproductive objectives, this assists women in selecting an effective contraceptive technique.

Respect for Women’s Autonomy and Rights:

Women’s right to make their own decisions about their reproductive health is upheld by CAC. It acknowledges that every woman has a special situation, and that her decisions should be respected without bias or pressure.

Importance of Comprehensive Abortion Care

Here is teh importance of CAC explained in detail.

Promoting Women’s Health and Well-being:

Women’s health and safety are given top priority by CAC, lowering the likelihood of unsafe and unauthorized abortions. Abortion is a safe medical procedure with few risks when done by qualified specialists.

Reducing Maternal Mortality and Morbidity:

Abortions performed unsafely play a substantial role in maternal mortality and morbidity rates around the world. By guaranteeing that women have access to secure abortion services, CAC plays a crucial part in lowering these dangers.

(ads1)

Supporting Reproductive Rights:

An essential reproductive right is the availability of comprehensive abortion care. Women are given more control over their bodies and destinies thanks to CAC, which promotes gender equality and women’s empowerment.

Addressing Stigma and Emotional Well-being:

The emotional and psychological effects of abortion are acknowledged by CAC. It aids women in overcoming any stigma or emotional difficulties they may experience by offering counseling and support.

Preventing Unintended Pregnancies:

Contraceptive services are a part of CAC, which supports family planning and reproductive health by assisting women in preventing future unplanned pregnancies.

Happy family

Conclusion

Comprehensive abortion care includes counseling, support, and empowerment in addition to medical treatments. It is a comprehensive strategy that defends women’s rights, respects their autonomy, and advances their health. To protect women’s health, lower maternal mortality, and advance reproductive justice, access to CAC must be ensured. In order to guarantee that women have the support and tools they need to make educated decisions about their reproductive health, it is critical to promote and emphasize comprehensive abortion care as societies change.

UWorld Alternatives : Medical Students can Use these tools for USMLE Preparation 2025

UWorld Alternatives: Use these tools for USMLE Preparation 2024

(toc)Table of Contents

What is USMLE?

The United States Medical Licensing Examination (USMLE) is a famous three-step standardized examination that medical students and graduate doctors must pass in order to obtain a clinical practice license to practice medicine in the United States of America.

The exam is designed to assess and evaluate a physician’s ability to apply clinical knowledge, health concepts, and principles that are important for the effective patient care and the practice of medicine in healthcare settings.

Here’s a brief overview of the three steps:

  1. USMLE Step 1:

    • This step focuses on the basic sciences that form the foundation of medical practice, including anatomy, biochemistry, physiology, pharmacology, microbiology, pathology, and behavioral sciences.
    • It is typically taken after the second year of medical school.
  2. USMLE Step 2:

    • Divided into two parts:
      • Step 2 CK (Clinical Knowledge): Tests clinical knowledge through multiple-choice questions covering internal medicine, surgery, pediatrics, psychiatry, obstetrics and gynecology, and other specialties.
      • Step 2 CS (Clinical Skills): This component was previously used to assess clinical skills through patient interactions, but it has been permanently discontinued as of January 2021.
    • Step 2 CK is usually taken during the fourth year of medical school.
  3. USMLE Step 3:

    • Focuses on clinical management and the ability to apply medical knowledge in patient care scenarios.
    • It is usually taken during or after the first year of residency.

Passing all three steps of the USMLE is a requirement for obtaining a medical license in the U.S. and is often necessary for international medical graduates (IMGs) who wish to practice in the country.

TINEA FACIEI: Bad-looking itch on your face Diagnosis!

What is tinea faciei?

It is infection of face with a dermatophyte fungus. It does not include infection of beard and moustache area, which is called tinea barbae. Tinea faciei is uncommon and often misdiagnosed at first.

What causes tinea faciei?

Tinea faciei can be due to an anthropophilic (human) fungus such as Trichophyton rubrum (T rubrum). Infection often comes from the feet (tinea pedis) or nails (tinea unguium) originally. Zoophilic (animal) fungi such as Microsporum canis (M canis) is acquired from cats and dogs, and T verrucosum, from farm cattle, are also common.

How is tinea faciei diagnosed?

Tinea faciei resembles tinea corporis (ringworm). It may be acute (sudden onset and rapid spread) or chronic (slow extension of a mild, barely inflamed, rash). There are round or oval red scaly patches, often less red and scaly in the middle or healed in the middle. Lesions are usually asymmetric and it is often unilateral. It is frequently aggravated by sun exposure. It may presenta as kerion (fungal abscess).

What should we care if we have tinea faciei?

It is essential to look for and treat tinea infection elsewhere (look at the feet, groins, and nails) and in a suspected zoophilic infection, identify, isolate and treat the source animal.

Look at these dermatology question for your upcoming exams. 

Tinea faciei pathophysiology?

-Tinea faciei is the name used for infection of face with a dermatophyte fungus(T.rubrum)

Clinicalℹ️:round and oval red 🔴(less scaly in middle) scaly patches Acute(Sudden onset and rapid spread),Triggered by sun ☀️ 

Read how to differentiate tinea from acne vulgaris here. 

What is treatment of Tinae faciei?

✅Terbina,itraconzole, fluconazole

Here is dose and route written for treatment of Tinea faciei:

  1. Cap Itraconazole 100 mg PO BD 4 weeks OR
  2. Tab Itraconazole 250 mg PO OD 6 weeks (upto 12 weeks for onychomycosis) OR
  3. Cap fluconazole 150 mg once weekly upto 6 weeks
  4. Oint clotrimazole or terbinafine or  Ketoconazole luliconazole or miconazole nystatin or topically one to three times a day 
  5. Antihistamines like ceterizine, fexofenadine, levoceterizine or ebastine 
  6. ketoconazole soap can be used.

Introduction of Tumor markers

Tumor markers are soluble glycoproteins that are found in the blood, urine, or tissues of patients with certain types of cancer.
They are used to help diagnose cancer, monitor treatment, and check for recurrence.

Where do tumor markers come from ?

They are typically produced by tumor cells, but in some cases they may be produced by the body in response to malignancy or to certain benign conditions.
Not all tumors or cancers give tumor markers but some may. They sometimes may not necessarily be produced due to cancer but by normal  condition or tissue as well.

What the common tumor markers and what are they used to diagnose ? List

Here are some common tumor markers and the types of cancer they are associated with:

Prostate-Specific Antigen (PSA) – 

Used primarily to diagnose and monitor prostate cancer.

CA 125 (Cancer Antigen 125) – 

Used mainly for ovarian cancer diagnosis and monitoring, though it can also be elevated in other conditions.

Carcinoembryonic Antigen (CEA) – 

Often used in the management of colorectal cancer, but can also be elevated in cancers of the lung, breast, pancreas, and stomach.

CA 19-9 (Cancer Antigen 19-9) – 

Primarily used for pancreatic cancer diagnosis and monitoring, and sometimes for gastrointestinal cancers.
Not all tumors or cancers give tumor markers but some may. They sometimes may not necessarily be produced due to cancer but by normal  condition or tissue as well.

Alpha-Fetoprotein (AFP) – 

Used to diagnose and monitor liver cancer (hepatocellular carcinoma) and germ cell tumors, such as testicular cancer.

Beta-Human Chorionic Gonadotropin (β-hCG) – 

Used to diagnose and monitor germ cell tumors, including testicular and ovarian cancers.

HER2/neu – 

Not a traditional marker in blood tests, but a protein overexpressed in some breast cancer cells; it is used to guide treatment decisions for HER2-positive breast cancers.

BRCA1 and BRCA2 – 

Genetic mutations rather than traditional markers, these are used to assess risk for breast and ovarian cancers.

Calcitonin – 

Elevated levels can indicate medullary thyroid cancer.

S100 – 

Used primarily to monitor melanoma.
These markers are most effective when used alongside other diagnostic tools, as they can sometimes be elevated in non-cancerous conditions or not elevated in all cases of cancer.

Varicella zoster


Definition of Postherpetic neuralgia (PHN)

Postherpetic neuralgia (PHN) is a localized dermatomal neuropathic pain experienced 1 month after herpes zoster.

Immunosuppression is the commonest risk factor for PHN.

Varicella-zoster virus (VZV) is the causative agent of varicella, or ” the chickenpox,” and herpes zoster, or “shingles.”

Acute herpes zoster typically presents with a rash that is painful but self-limited. Some patients may continue to experience pain for months to years after the resolution of the rash, a condition known as postherpetic neuralgia (PHN).

Risk factors for post herpetic neuralgia

  1. age more than 60 years
  2. severe pain during acute herpes zoster
  3. severe or more rash with acute herpes zoster

How long does the pain of PHN lasts?

Generally pain of PHN lasts from few months to several. Most of them last for few months.
Is there sensory loss  with PHN?
Yes, the same dermatomes involved with herpes and PHN may also have sensory loss like loss of thermal, tactile, inprick or vibration sensations.
Occasionally the sensory deficit may cross dermatome margins but the uninvolved contralateral dermatomes are normal or unimpaired.
herpes zoster

Does PHN cause allodynia?

Allodynia is a condition that causes pain from the stimuli that normally wouldnt cause pain suchas light touch, brushing, combing hair, wearing clothing etc.
And PHN may occasionally cause allodynia as well.

Pain in Postherpetic neuralgia (PHN)

Broadly type of pain in PHN is divided into two broad categories spontaneous and stimulus evoked.

Spontaneous pain can be either continuous (burning, aching, throbbing) or intermittent (stabbing, shooting, electric-shock-like pain). Stimulus-evoked pain can present as allodynia and hyperalgesia. Allodynia is the commonest type of pain reported in PHN.

Diagnosis of PHN

The diagnosis of PHN is made when localized neuropathic pain persists beyond three months in the same distribution as a preceding documented episode of acute herpes zoster.
Testing for varicella-zoster virus (VZV) antibodies in the blood or cerebrospinal fluid is available and may be useful in atypical cases to confirm past exposure to the virus; however, positive tests do not specify PHN as the source of pain
  1. Trigeminal neuropathy
  2. Other forms of craniofacial pain
  3. Acute radiculopathy
  4. Diabetic amyotrophy and idiopathic lumbosacral radiculoplexus neuropathy
  5. Recurrent acute herpes zoster

Treatment of  Postherpetic neuralgia (PHN) with local anesthetics

Local anesthetics act by suppressing sodium channels and decreasing ectopic discharges, thus reducing membrane excitability.

Lignocaine has faster onset of action (2-3 min) of but the duration of action (2 h) in contrast bupivacaine though is slow to act but has a continued activity for longer time (4-8 h).
