Diseases of the Ear Indian Medical PG Question 1: The web-based IT system for case-based surveillance under National Tuberculosis Elimination Programme (NTEP, formerly RNTCP) is
- A. NIKSHAY (Correct Answer)
- B. E-TB Tracker
- C. SURAKSHA
- D. SAFETY-NET
Diseases of the Ear Explanation: ***NIKSHAY***
- **NIKSHAY** is the official web-based IT system used by the National Tuberculosis Elimination Programme (NTEP, formerly RNTCP) in India for **case-based surveillance** and monitoring of TB cases.
- Launched in 2012, it facilitates **real-time data entry**, tracking of patient outcomes, drug logistics management, and program monitoring, significantly improving the efficiency of TB control efforts.
- It enables **notification of all TB cases**, both from public and private sectors, ensuring comprehensive surveillance.
*E-TB Tracker*
- **E-TB Tracker** is not the designated IT system for TB surveillance under NTEP in India.
- This term may refer to other electronic tracking systems used in different contexts, but NIKSHAY remains the official platform for India's TB programme.
*SURAKSHA*
- **SURAKSHA** means safety or protection in Hindi and is not associated with any specific web-based IT system for TB surveillance under NTEP.
- This is not a recognized TB surveillance platform in the Indian context.
*SAFETY-NET*
- **SAFETY-NET** is a generic term referring to social protection programs or health support systems.
- There is no specific NTEP initiative for TB surveillance identified by this name.
Diseases of the Ear Indian Medical PG Question 2: A 25-year-old woman presents with episodes of dizziness, tinnitus, and hearing loss in the right ear. What is the most likely diagnosis?
- A. Labyrinthitis
- B. Ménière's disease (Correct Answer)
- C. Acoustic neuroma
- D. Benign paroxysmal positional vertigo
Diseases of the Ear Explanation: ***Ménière's disease***
- This condition is characterized by a classic triad of **episodic vertigo (dizziness)**, fluctuating **sensorineural hearing loss**, and **tinnitus**, often accompanied by aural fullness, typically affecting one ear.
- The symptoms arise from an accumulation of **endolymph** in the inner ear, leading to increased pressure and dysfunction.
*Labyrinthitis*
- **Labyrinthitis** is an inflammation of the inner ear, usually viral, causing sudden, severe **vertigo** potentially with hearing loss and tinnitus.
- Unlike Meniere's disease, **hearing loss** and **tinnitus** in labyrinthitis are usually constant rather than episodic or fluctuating.
*Acoustic neuroma*
- An **acoustic neuroma** (vestibular schwannoma) is a benign tumor on the eighth cranial nerve, often causing **gradual, progressive unilateral hearing loss**, tinnitus, and **balance issues**, but typically not episodic severe dizziness.
- While it can cause hearing loss and tinnitus, the **episodic nature of vertigo** is less common than in Ménière's disease.
*Benign paroxysmal positional vertigo*
- **BPPV** is characterized by sudden, **brief episodes of vertigo** triggered by specific head movements, caused by dislodged **otoconia** in the semicircular canals.
- Critically, BPPV does **not** typically cause associated **hearing loss or tinnitus**, which are prominent symptoms in the presented case.
Diseases of the Ear Indian Medical PG Question 3: A 45-year-old gentleman reports decreased hearing in the right ear for the last two years. On testing with a 512 Hz tuning fork, the Rinne's test without masking is negative on the right ear and positive on the left ear. With the Weber's test, the tone is perceived as louder in the left ear. Patient most likely has -
- A. Right conductive hearing loss (Correct Answer)
- B. Right sensorineural hearing loss
- C. Left sensorineural hearing loss
- D. Left conductive hearing loss
Diseases of the Ear Explanation: ***Right conductive hearing loss***
- A **negative Rinne's test** (bone conduction louder than air conduction) in the right ear indicates **conductive hearing loss** on that side
- However, in true conductive hearing loss, **Weber should lateralize to the affected (right) ear** due to the occlusion effect, not to the left ear
- The Weber lateralizing to the left ear with a negative Rinne on the right suggests this may be a **false negative Rinne** due to lack of masking, where sound crosses over to the better left ear
- This combination is atypical for pure conductive loss and requires repeat testing with proper masking
*Right sensorineural hearing loss*
- In **sensorineural hearing loss**, Rinne's test should be **positive** (air conduction > bone conduction) on both sides, though both may be reduced on the affected side
- **Weber lateralizes to the unaffected (left) ear**, which matches the given finding
- The **negative Rinne on the right ear without masking** is likely a **false negative** due to sound crossing over to the better left ear during bone conduction testing
- This is the **most consistent interpretation** when Rinne testing is done without masking, but traditionally the question frame suggests conductive loss
*Left sensorineural hearing loss*
- Would show **positive Rinne bilaterally** with reduced hearing on the left
- **Weber would lateralize to the right ear** (the better ear), contradicting the given findings
- This option is clearly inconsistent with the clinical findings
*Left conductive hearing loss*
- Would show **negative Rinne on the left** and positive on the right
- Weber would lateralize to the left ear (affected side in conductive loss)
- The **Rinne findings contradict this**, as the right ear shows negative Rinne, not the left
Diseases of the Ear Indian Medical PG Question 4: A 45-year-old female presents with hearing loss, vertigo, and tinnitus in her right ear. Which condition is most likely?
- A. Acoustic neuroma
- B. Meniere's disease (Correct Answer)
- C. Chronic otitis media
- D. Otosclerosis
Diseases of the Ear Explanation: ***Meniere's disease***
- This condition classically presents with the triad of **vertigo**, **tinnitus**, and **fluctuating sensorineural hearing loss**, often in one ear.
- The symptoms are thought to be caused by an excess of fluid, known as **endolymphatic hydrops**, in the inner ear.
*Acoustic neuroma*
- While it can cause **unilateral hearing loss** and **tinnitus**, it typically causes more persistent, progressive symptoms and **vertigo is less common or severe** than in Meniere's.
- An acoustic neuroma is a **benign tumor** on the vestibulocochlear nerve (cranial nerve VIII) that can also cause **facial numbness** or weakness in later stages.
*Chronic otitis media*
- This condition primarily causes **conductive hearing loss** due to damage to the middle ear structures and often involves **tympanic membrane perforation** and **otorrhea**.
- It does not typically present with vertigo unless there is an erosion into the inner ear (labyrinthitis), and **tinnitus is less prominent** than in Meniere's disease.
*Otosclerosis*
- This condition primarily causes **progressive conductive hearing loss** in younger to middle-aged adults, often bilaterally, due to abnormal bone growth in the middle ear.
- While **tinnitus can occur**, **vertigo is rare** and not a primary symptom, distinguishing it from Meniere's disease.
Diseases of the Ear Indian Medical PG Question 5: Identify the investigation being carried out in the image.
- A. Fluoroscopy
- B. X-ray after alkali ingestion
- C. X-ray after acid ingestion
- D. Barium Swallow (Correct Answer)
Diseases of the Ear Explanation: ***Barium Swallow***
- The image shows a contrast material, characteristic of **barium**, flowing through the esophagus, captured as a sequence of X-ray images, which is the definition of a barium swallow study.
- This **dynamic imaging** allows for evaluation of swallowing function and esophageal motility.
*Fluoroscopy*
- While a barium swallow uses **fluoroscopy** to visualize the movement of barium, fluoroscopy itself is the technique, not the specific investigation being performed. The image depicts the result of a specific type of fluoroscopic examination.
- Fluoroscopy is a general term for real-time X-ray imaging, whereas "Barium Swallow" specifies the type of study being done on the upper GI tract.
*X-ray after alkali ingestion*
- This scenario would typically involve viewing the effects of **corrosive injury** to the esophagus, which would appear as mucosal damage, narrowing, or perforation. The image does not show these features; instead, it shows smooth passage of contrast.
- There is no visible evidence of an acute or chronic injury pattern consistent with **alkali ingestion**, which often leads to severe burns or strictures.
*X-ray after acid ingestion*
- Similar to alkali ingestion, acid ingestion also causes **corrosive injury**, typically affecting the stomach more severely than the esophagus. The image does not demonstrate these pathological changes.
- The smooth, unobstructed flow of contrast in multiple frames is indicative of normal esophageal function rather than the sequelae of corrosive ingestion.
