What is the nerve supply of Submandibular gland:

NEET PG Jan-2019
A. Auriculotemporal nerve
B. Lingual nerve
C. Glossopharyngeal nerve
D. Inferior alveolar nerve
Correct Ans: B

Answer B. Lingual Nerve

  • The submandibular glands receive autonomic innervation through parasympathetic and sympathetic fibres, which directly and indirectly regulate salivary secretions respectively.


  • Parasympathetic innervation originates from the superior salivatory nucleus through pre-synaptic fibres, which travel via the chorda tympani branch of the facial nerve (CN VII).

  • The chorda tympani then unifies with the lingual branch of the mandibular nerve (CNViii) before synapsing at the submandibular ganglion and suspending it by two nerve filaments.

  • Post-ganglionic innervation consists of secretomotor fibres which directly induce the gland to produce secretions, and vasodilator fibres which accompany arteries to increase blood supply to the gland. Increased parasympathetic drive promotes saliva secretion.



  • Sympathetic innervation originates from the superior cervical ganglion, where post-synaptic vasoconstrictive fibres travel as a plexus on the internal and external carotid arteries, facial artery and finally the submental arteries to enter each gland. Increased sympathetic drive reduces glandular blood flow through vasoconstriction and decreases the volume of salivary secretions, resulting in a more mucus and enzyme-rich saliva.

Which of the following exocrine glandular ducts are not obstructed in cystic fibrosis:

NEET PG Jan-2019
A. Pancreas
B. Lung
C. Sweat gland
D. All of above
Correct Ans: C

Answer C. Sweat gland

Most CF patients have 3 distinct abnormal characteristics:

  • The ducts of the mucus-secreting glands are obstructed due to an increase in viscosity of these secretions leading to glandular dilatation and destruction.

  • CF patients are prone to chronic bacterial colonization and infections.

  • The sweat glands are not obstructed in CF patients because in serous glands such as sweat glands there are abnormal concentrations of inorganic ions, rather than glandular obstruction with thick mucus.

  • The quantitative pilocarpine iontophoresis sweat test is a uniformly accepted method for diagnosing CF. The sweat gland ducts must be patent for this test.

  • Obstruction of airways leads to bronchiectasis and atelectasis; pancreatic duct obstruction leads to pancreatitis and malabsorption; and plugging of bile ducts leads to obstructive jaundice.

What are Gitter cells:

NEET PG Jan-2019
A. Macroglia
B. Modified macrophages in CNS
C. Astrocytes
D. Oligodendrocytes
Correct Ans: B

Answer B) Modified macrophages in CNS

Gitter cells:

  • These cells are macrophages and because of their appearance they are called “gitter cells”.

  • They look this way because they are lipid-laden.


  • These macrophages are thought to be mainly derived from circulating blood monocytes, but some probably originate from resident microglia.

  • Any time there is parenchymal damage (e.g. inflammation, infarction, parasite migration) these cells will phagocytose lipid from degenerate myelin and cellular debris.

  • These lipid-laden macrophages migrate to the perivascular spaces and leave the CNS via the blood or CSF.

Hormone predominately secreted after 14 day on endometrium is?

NEET PG Jan-2019
A. Progesterone
B. Estrogen
Correct Ans: A

Ans:A. Progesterone.

Events of ovarian cycle:

  • By 5th day, ovarian follicle is sufficiently developed.

    • Secretes considerable quantities of estrogen.

  • During pre-ovulatory phase:

    • Estrogen influencesendometrial proliferative changes.

    • Hence, “Preovulatory phase of uterine cycle” also referred “Proliferative phase”.

  • During post-ovulatory phase:

    • Endometrium enters secretory phase.

    • Hence, “Postovulatory phase of uterinecycle” also referred “Secretory phase”.

    • Due to combined action of estrogen & progesterone.

  • Progesterone:

    • More important & responsible for secretory changes.

    • Peaks on 21st day.

  • End of secretory phase:

    • Estrogen-primed endometrium.

    • Degeneration of corpus luteum declines estrogen & progesterone levels.

    • Results in withdrawal bleeding – Menstruation.


Peripheral chemoreceptors respond to hypoxia using which channel?

NEET PG Jan-2019
A. Calcium channel
B. Sodium channel
C. Potassium channel
D. Chloride channel
Correct Ans: C

Ans:C. Potassium channel.

  • Carotid bodies are composed of glomus cells (also called type I), which are of neuronal phenotype and contain a variety of neurotransmitters.

  • Glomus cells are in functional contact with the afferent nerve endings.

    • Glomus cells are initial site(s) of sensory transduction.

  • Hypoxia releases transmitter(s) from glomus cells, which in turn by depolarizing the sensory nerve ending leads to an increase in sensory discharge.

  • One hypothesis assumes that a K+-channel protein is an O2 sensor and that hypoxia depolarizes glomus cells by inhibiting the K+ channel, leading to an increase in cytosolic Ca2+, resulting in transmitter(s) release.

LCAT deficiency increases the following

NEET PG Jan-2019
D. Chylomicron
Correct Ans: A

Answer: A. HDL

  • Lecithin cholesterol acyltransferase deficiency (LCAT deficiency) is a disorder of lipoprotein metabolism.
  • A deficiency of LCAT causes accumulation of unesterified cholesterol in certain body tissues. Cholesterol effluxes from cells as free cholesterol and is transported in HDL as esterified cholesterol.
  • LCAT is the enzyme that esterifies the free cholesterol on HDL to cholesterol ester and allows the maturation of HDL.
  • LCAT is the enzyme that esterifies the free cholesterol on HDL to cholesterol ester and allows the maturation of HDL. LCAT deficiency does not allow for HDL maturation resulting in its rapid catabolism of circulating apoA-1 and apoA-2. The remaining form of HDL resembles nascent HDL.

NEET PG Jan-2019
A. Vit B3
B. Vit B6
C. Vit B9
D. Vit B1
Correct Ans: D

Answer: D. Vit B1

  • Wet beriberi is the term used for thiamine deficiency with cardiovascular involvement.
  • In the first stage, peripheral vasodilation occurs, leading to a high cardiac output state. This leads to salt and water retention mediated through the renin-angiotensin-aldosterone system in the kidneys.
  • A more rapid form of wet beriberi is termed acute fulminant cardiovascular beriberi, or Shoshin beriberi.
  • The predominant injury is to the heart, and rapid deterioration follows the inability of the heart muscle to satisfy the body’s demands because of its own injury.
  • In this case, edema may not be present. Instead, cyanosis of the hands and feet, tachycardia, distended neck veins, restlessness, and anxiety occur.

Approximately 40% of patients may have each of the following features 4:

  • expansion of an involved sinus

  • remodelling and thinning of the bone sinus walls

  • erosion of the sinus wall



Identify the  instrument:


NEET PG Jan-2019
A. Maddox rod
B. Maddox wing
C. Maddox glass
D. Red glasse
Correct Ans: A

Answer. A. Maddox rod

  • The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance.

  • The test is based on the principle of diplopic projection

  • The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens, which refracts light rays so that a point source of light is seen as a line or streak of light.

  • Due to the optical properties, the streak of light is seen perpendicular to the axis of the cylinder.

The Maddox rod test should be used in cases of:

    • Small to moderate (i.e..<25pd) vertical deviations where there is simultaneous perception and normal retinal correspondence (NRC)

    • Decompensated phorias.

    • Acquired strabismus (rather than congenital or early onset)


Following test is used to diagnose which ocular condition as shown in image:


NEET PG Jan-2019
A. Strabismus
B. Heterophoria
C. Both A & C
D. None of the above
Correct Ans: C

Answer. C. Both A & C

Given image is cover-uncover test

  • The cover-uncover test to diagnose various types of tropias, which is a medical term for strabismus.

  • The single cover test is a test is used to determine if there is a heterotropia or tropia, which is a manifest strabismus or misalignment that is always present.

  • The first eye is covered for approximately 1-2 seconds. As this eye is covered, the uncovered eye is observed for any shift in fixation.

  • The cross-cover test, or alternating cover test is usually employed to detect heterophoria.

  • One eye is covered, and then the cover is moved immediately over to the other eye. With heterophoria, when the cover is moved to the other eye, the eye that has just been uncovered can be seen to move from a deviated point.

  • The difference between heterotropia and heterophoria can be easily understood as follows.

  • With heterotropia, a correcting movement of the eye can be detected already by the simple cover test; with heterophoria, such correcting movement only takes place in the cross-cover test.

  • People with heterophoria are able to create and maintain binocular fusion through vergence, and the cross-cover test purposely breaks this fusion, making the latent misalignment visible.

Drug used in acute congestive glaucoma are:

NEET PG Jan-2019
A. Atropine
B. Pilocarpine
C. Acetazolamide
D. Both B & C
Correct Ans: D

Answer. D. Both Pilocarpine & Acetazolamide

Management of angle closure glaucoma

  • Acute congestive glaucoma also is known as acute angle closure glaucoma.

  • Immediate medical therapy in acute AC consists of commencing IOP-lowering eye medications such as topical ß-blocker, a2-agonist and even prostaglandin analogues as soon as possible.

  • Once the IOP is sufficiently reduced to allow iris reperfusion, pilocarpine is instilled to induce miosis in an attempt to widen the anterior chamber angles and reestablish aqueous outflow.

  • Mydriatic drugs such as atropine, cyclopentolate, tropicamide and phenylephrine are precipitating factor for angle closure glaucoma, so not used (contraindicated) in its treatment.

True statement about given condition of eye except:


NEET PG Jan-2019
A. Arise from any part of conjunctiva
B. Can cause Astigmatism
C. Surgery is treatment of choice
D. UV exposure is risk factor
Correct Ans: A

Answer. A. Arise from any part of conjunctiva

Given condition is Pterygium

  • Pterygium is a non- cancerous (non-neoplastic) growth of conjunctiva.
  • Characterized by a wing-shaped fold of conjunctiva upon the cornea from either side within the interpalpebral fissure.
  • Pterygium is always situated in the palpebral aperture.
  • Pathologically Pterygium is a degenerative & hyperplastic condition of conjunctiva.
  • The subconjunctival tissue undergoes elastotic degeneration & proliferates as vascularised granulation tissue under the epithelium, which ultimately encroaches the cornea.
  • The corneal epithelium, Bowman’s layer & stroma are destroyed.

Etiology & Clinical features

  • More common in people with excess outdoor exposure to sunlight (UV rays) dry, heat, high wind & abundance of dust.
  • Clinically, presents as a triangular fold of conjunctiva encroaching the cornea in the area of palpebral aperture, usually on the nasal side.
  • Other findings are stocker’s line (deposition of iron).
  • Pterygium is an asymptomatic condition in the early stages, except for cosmetic intolerance.
  • Visual disturbance or corneal astigmatism may occur.
  • Visual disturbances are due to encroachment of pterygium on pupillary area or corneal astigmatism.
  • Occasionally diplopia may occur due to limitation of ocular movements.


  • Asymptomatic pterygium which is not progressive is best left alone.

  • Surgical excision is the only satisfactory treatment.

What is against the rule correction in astigmatism:

NEET PG Jan-2019
A. -1.25 cyl 90
B. -2 spherical 180
C. -3 cyl 180
D. +2 cyl 180
Correct Ans: A

Answer. A. -1.25 cyl 90

Astigmatism Correction Options


  • Astigmatism, like nearsightedness and farsightedness, usually can be corrected with eyeglasses, contact lenses or refractive surgery.
  • In addition to the spherical lens power used to correct nearsightedness or farsightedness, astigmatism requires an additional “cylinder” lens power to correct the difference between the powers of the two principal meridians of the eye.
  • So an eyeglasses prescription for the correction of myopic astigmatism, for example, could look like this: -2.50 -1.00 x 90.
  • The first number (-2.50) is the sphere power (in diopters) for the correction of myopia in the flatter (less nearsighted) principal meridian of the eye.
  • The second number (-1.00) is the cylinder power for the additional myopia correction required for the more curved principal meridian. In this case, the total correction required for this meridian is -3.50 D (-2.50 + -1.00 = -3.50 D).
  • The third number (90) is called the axis of astigmatism. This is the location (in degrees) of the flatter principal meridian, on a 180-degree rotary scale where 90 degrees designates the vertical meridian of the eye, and 180 degrees designates the horizontal meridian.

If you wear soft toric contact lenses for astigmatism correction, your contact lens prescription will likewise include a sphere power, cylinder power and axis designation.

Gas permeable contact lenses are also an option. Because these lenses are rigid and optically replace the cornea as the refracting surface of the eye, a cylinder power and axis may or may not be needed,

A child has ptosis and poor levator function. What surgery will you do?

NEET PG Jan-2019
A. Levator muscle resection
B. Mullerectomy
C. Fasanella Servat surgery
D. None of the above
Correct Ans: B

Answer. B. Mullerectomy

  • Muller muscle resections are typically used for repair of minimal ptosis (2 mm) and are generally considered superior to the Fasanella-Servat procedure (tarsoconjunctival mullerectomy) in maintaining eyelid contour and preserving the tarsus.
  • When levator function is poor, the surgeon should consider utilizing the accessory elevators of the eyelid in ptosis repair. This type of surgery is most commonly required in congenital ptosis with poor levator function or in various forms of neurogenic ptosis with poor levator function.
  • Frontalis suspension surgery performed when levator function is poor or absent, the eyelid is suspended directly from the frontalis muscle so that movement of the brow is efficiently transmitted to the eyelid. Thus, the patient is able to elevate the eyelid by using the frontalis muscle to lift the brow. Frontalis suspension can be performed transcutaneously or transconjunctivally.


Which drug causes ocular hypotension with apnea in an infant?

NEET PG Jan-2019
A. Latanoprost
B. Timolol
C. Brimonidine
D. Dorzolamide
Correct Ans: C

Answer. C. Brimonidine

  • Oral therapy: The oral regimen of vitamin A is 200,000 IU on day of presentation, next day, and 2-4 weeks later.

  • Children less than 1 year of age or less than 8 kg should receive half the dose of the above dose. Repeat 200,000 IU every 6 months up to 6 years of age to prevent recurrence.

  • Parenteral therapy: If the patient has severe disease, is unable to take oral feeds, or has malabsorption, the preferable dose is 100,000 IU of vitamin A given intramuscularly.

  • Children with severe measles should also receive vitamin A as they are very likely to be benefited from such therapy both in terms of saving sight and reducing case fatality.

  • Prevention

Prophylaxis consists of periodic administration of Vitamin A supplements. WHO recommended schedule, which is universally recommended is as follows:

  • Infants 6–12 months old and any older children weighing less than 8 kg – 100,000 IU orally every 3–6 months
  • Children over 1 year and under 6 years of age – 200,000 IU orally every 6 months

Confounding factor is defined as

NEET PG Jan-2019
A. Factor associated with both the exposure and the disease and is distributed unequally in study and control groups.
B. Factor associated with exposure only and is distributed unequally in study and control groups.
C. Factor associated with both the exposure and the disease and is distributed equally in study and control groups
D. Factor associated with the disease and is distributed equally in study and control groups.
Correct Ans: A

Ans. A. Factor associated with both the exposure and the disease and is distributed unequally in study and control groups.

  • Epidemiological studies search for the causes of diseases, based on associations with various risk factors that are measured in the study. In addition to the exposures that the study is investigating, there may be other factors that are associated with the exposure and are also risk factors for the disease. If the prevalence of these other factors differs between groups being compared, they will distort the observed association between the disease and exposure under study. Such variables may partially or completely account for any apparent association between an exposure variable and disease. These distorting factors are called confounding factors or variables.

  • Thus a Confounding factor is defined as one which is associated with both the exposure and the disease and is distributed unequally in study and control groups. It is itself a risk.factor.for the disease.

  • Its advantage lies in the fact that it can also be used when more than two groups are to be compared.
  • By using this test, we can find out if the difference between two proportions or ratios has occurred by chance. The steps involved are-
  1. Testing the null hypothesis.
  2. Applying chi-square test.
  3. Calculating the degree of freedom.
  4. Comparing with probability tables.

C. Test applied when separate observations are made on individuals of two separate groups, and these need to be compared
D. None
Correct Ans: A

Ans. A. Test used to assess quantitative observations before and after an intervention

Paired t-tests

  • The paired t-test is used to compare the values of means from two related samples, for example in a ‘before and after’ scenario.

  • The difference between the means of the samples is unlikely to be equal to zero (due to sampling variation) and the hypothesis test is designed to answer the question “Is the observed difference sufficiently large enough to indicate that the alternative hypothesis is true”.

  • The answer comes in the form of a probability – the p-value.

Risk of genetic diseases in consanguinous marriage between first cousins?

NEET PG Jan-2019
A. 1-2%
B. 4-8%
C. 8-10%
D. 12-14%
Correct Ans: B

Ans. B.4-8%

Consanguinity is a marriage between relatives and has various degrees. Closely related individuals have a higher chance of carrying the same alleles than those less closely related and therefore children from consanguineous marriages are more frequently homozygous for various alleles than those from non-consanguineous unions.

Generally speaking, frequency of congenital malformations among newborns of first cousin unions is about 2 times the frequency among the general population. In other words instead of a rate of 2-3% of birth defects in the general population, the risk to first cousin couples is around 4-6%.

NEET PG Jan-2019
A. Cloxacillin
B. Cefazolin
C. Ceftriaxone
D. Ampicillin
Correct Ans: A

Ans. A. Cloxacillin

  • The beta lactamase-resistant penicillins have been recommended in the treatment of mastitis. These include cloxacillin, dicloxacillin, or flucloxacillin.
  • Because penicillins are acidic, they are poorly concentrated in human milk, which is also acid.
  • Therefore, cloxacillin and its congeners tend to treat cellulitis well, but they are less effective in eradicating adenitis, the most likely precursor of breast abscess.
  • When patients are allergic to penicillins, cephalexin or clindamycin may be the alternative to erythromycin.
  • Combination like co-amoxiclav should be avoided because of fear of inducing MRSA

NEET PG Jan-2019
A. Excitement phase
B. Plateau phase
C. Orgasm phase
D. Refractory phase
Correct Ans: C

Ans. C. Orgasm phase

  • The male sexual response is described as a sequence of phases including 4 stages: sexual desire, arousal, orgasm (ejaculation) and resolution.

The male sexual dysfunction usually occurs in one or more of the three first stages of the sexual response cycle, including:

  • Dysfunctions of sexual desire (e.g. hypoactive sexual desire)
  • Arousal (e.g. erectile dysfunction)
  • Orgasm/ejaculation (e.g. premature ejaculation, retarded ejaculation or inability to ejaculate).
  • Premature ejaculation occurs due to the rapid evolution of the two first stages of the sexual response cycle and is not necessarily related to strong sexual arousal or changes in erection.
  • Premature Ejaculation seems to be a neurobiological problem that is related to low serotonin levels in those regions of the central nervous system that regulate ejaculation (brain and spinal cord).

NEET PG Jan-2019
A. Vaginal hysterectomy with pelvic floor repair
B. Pelvic floor repair
C. Sacrospinous fixation
D. Pessary
Correct Ans: A

Ans. A. Vaginal hysterectomy with pelvic floor repair

Uterine prolapse surgery is performed to remove the uterus and repair the weak tissue. Uterine prolapse frequently occurs in postmenopausal women who’ve had one or more vaginal deliveries.

Sagging of the pelvic muscles which leads to uterine prolapse can occur:

  • If supportive tissues are damaged during pregnancy and delivery
  • Due to estrogen loss
  • As a result of straining repeatedly over the years (chronic cough, constipation etc.)
  • Due to gravitational effects
  • Depending on factors like age of the woman, desire for becoming pregnant and the overall state of a woman’s health, the treatment plan is decided.
  • Here the woman is of old age (non gestational) and have 3rd degree of prolapse. So best management of choice will be Vaginal hysterectomy with pelvic floor repair.

  • Partial hydatidiform mole can be identified by ultrasound showing placenta tissue, some hygromatous cysts, some fetal oddities, but no clear fetus structure.
  • Ultrasound is strictly an indicator. After spontaneous abortion or dilation and curettage, tissue needs to be examined by pathology and cytogenetics needs to be determined.
  • If a triploid karyotype is determined as 69, XXX, 69XXY, or 69 XYY [6], then a partial mole can be confirmed.



Vulvar atrophy and itching are treated by-

NEET PG Jan-2019
A. Estrogen ointment
B. Antihistamines
C. Tamoxifen
D. None
Correct Ans: A

Ans. A. Estrogens ointment

  • Atrophic vaginitis, the medical term for this condition, occurs as a result of deterioration of the vaginal tissue.
  • It’s a common condition in postmenopausal women because as estrogen levels drop, the tissue that lines the vagina becomes thinner and more easily damaged.
  • Women with atrophic vaginitis may also experience vaginal itching, burning, frequent urination, or vaginal discharge.
  • Women can treat this condition topically with estrogen creams, tablets (Vagifem), or an estrogen-releasing ring placed in the vagina (Estring).
  • Oral estrogen, available with a doctor’s prescription, will also restore vaginal tissue.
  • Vaginal lubricants offer an alternative for women wary of using estrogen.
  • Moisturizers such as Replens, Astroglide, and Lubrin can reduce symptoms and make sexual intercourse more comfortable.

  • The inner ring represents the chorion, embryonic disc and decidua capsularis.
  • The outer ring represents the decidua parietalis.



Which part of scaphoid fracture is most susceptible to avascular necrosis?

NEET PG Jan-2019
A. Distal 1/3rd
B. Middle 1/3rd
C. Proximal 1/3rd
D. Scaphoid Tubercle
Correct Ans: C

Answer. C. Proximal 1/3rd

  • Scaphoid fractures (i.e. fractures through the scaphoid bone) are common, in some instances can be difficult to diagnose, and can result in significant functional impairment.


  • Scaphoid fractures account for 70-80% of all carpal bone fractures.
  • Although they occur essentially at any age, adolescents and young adults are most commonly affected.
  • Older patients falling in a similar manner are more likely to sustain a distal radial fracture (usually a Colles fracture).

Clinical Presentation

  • Classically there can be pain in anatomical snuffbox which is thought to have a sensitivity of ~90% and a specificity ~40%
  • Fractures can occur essentially anywhere along the scaphoid, but distribution is not even:
  1. waist of scaphoid: 70-80%
  2. proximal pole: 20%
  3. distal pole (or so-called scaphoid tubercle): 10%

NEET PG Jan-2019
A. Subperiosteal abscess of frontal bone
B. Subperiosteal abscess of ethmoid bone
C. Mucocele of frontal bone
D. Mucocele of ethmoid bone
Correct Ans: A

Answer. A. Subperiosteal abscess of frontal bone

  • Pott’s puffy tumor, first described by Sir Percivall Pott in 1760, is a rare clinical entity characterized by subperiosteal abscess associated with osteomyelitis.
  •   It is characterized by an osteomyelitis of the frontal bone, either direct or through haematogenous spread.
  •  This results in a swelling on the forehead, hence the name.
  •  The infection can also spread inwards, leading to an intracranial abscess.
  •  Pott’s puffy tumor can be associated with cortical vein thrombosis, epidural abscess, subdural empyema, and brain abscess.

Which statement is incorrect about the pathology shown in the image:

NEET PG Jan-2019
A. Tumor arise from epiphyseal to metaphyseal region
B. Tumor has distinct margin
C. Eccentric lesion
D. Chemotherapy is the treatment of choice
Correct Ans: D

Answer. D. Chemotherapy is the treatment of choice

Given image is of Giant cell tumor 

  • Giant cell tumors of bone, also known as osteoclastomas, are relatively common bone tumors and are usually benign.
  • They typically arise from the metaphysis of long bones, extend into the epiphysis adjacent to the joint surface, and have a narrow zone of transition.

Classic appearance

There are four characteristic radiographic features when a giant cell tumor is located in a long bone:

  • occurs only with a closed growth plate
  • abuts articular surface: 84-99% come within 1 cm of the articular surface 1
  • well-defined with non-sclerotic margin (though <5% may show some sclerosis 8)
  • eccentric: if large this may be difficult to assess


  • Classically, treatment is with curettage and packing with bone chips or polymethylmethacrylate (PMMA).


What should be the most likely diagnosis of this 65 year old lady presents with backache and following radiograph of the spine shown in image:

NEET PG Jan-2019
A. Osteoporosis
B. Spondylolisthesis
C. Spondylolysis
D. Discitis
Correct Ans: B

Answer. B. Spondylolisthesis

  • Spondylolisthesis is subluxation of lumbar vertebrae, usually occurring during adolescence.
  • It usually results from a congenital defect in the pars interarticularis (spondylolysis).
  • Spondylolisthesis is usually fixed (ie, permanent and limited in degree). It usually involves the L3-L4, L4-L5, or L5-S1 vertebrae.
  • Spondylolisthesis often occurs in adolescents or young adults who are athletes and who have had only minimal trauma; the cause is a lumbar vertebra weakened by a congenital defect in the pars interarticularis (spondylolysis).
  • This defect is easily fractured; separation of the fracture fragments causes the subluxation. Spondylolisthesis can also occur with minimal trauma in patients who are > 60 and have osteoarthritis.
  • If mild to moderate (subluxation of = 50%), spondylolisthesis, particularly in the young, may cause little or no pain.
  • Spondylolisthesis can predispose to later development of spinal stenosis.
  • If due to major trauma, spondylolisthesis can cause spinal cord compression or other neurologic deficits; these deficits rarely occur.

[This x-ray shows stage 1 spondylolisthesis of L5 on S1. The black arrow shows the posterior border of L5, which subluxes anterior to S1. The red arrow points to the spondylolysis (congenital defect in the pars interarticularis).]

Spondylolisthesis is staged according to the percentage of vertebral body length that one vertebra subluxes over the adjacent vertebra:

  • Stage I: 0 to 25%
  • Stage II: 25 to 50%
  • Stage III: 50 to 75%
  • Stage IV: 75 to 100%

Spondylolisthesis is evident on plain lumbar x-rays. The lateral view is usually used for staging. Flexion and extension views may be done to check for instability.


  • Usually symptomatic.
  • Physical therapy with lumbar stabilization exercises may be helpful.


Which of the following attitude will be seen in a patient with posterior dislocation of hip?

NEET PG Jan-2019
A. Flexion, Abduction, Internal rotation
B. Flexion, Adduction, Internal rotation
C. Flexion, Abduction, External rotation
D. Flexion, Adduction, External rotation
Correct Ans: B

Answer. B. Flexion, Adduction, Internal rotation

  • Dislocations are usually posterior, and occasionally anterior, or central through the acetabulum.
  • Posterior dislocation: Hip is flexed, adducted, and internally rotated, and leg is shortened.
  • Anterior dislocation: Hip is flexed, abducted, and externally rotated, and leg is shortened.
  • Central dislocation: Trochanter is displaced medially. One may be able to feel the head of femur rectally. There is no shortening.


Most common joint involved in septic arthritis:

NEET PG Jan-2019
A. Knee
B. Hip
C. Shoulder
D. Elbow
Correct Ans: A

Answer. A. Knee

Septic arthritis (Acute suppurative arthritis)

  • Septic arthritis refers to pyogenic infection of a joint, i.e., infection of a joint by pyogenic organism (bacteria).
  • The joint can become infected by : –
  1. Hematogenous spread from a distant site (most common route).
  2. Direct invasion through a penetrating wound, intra articular injection, arthroscopy.
  3. Direct spread from adjacent osteomyelitis especially in joints where Metaphysis is intra articular e.g., hip and shoulder.

Clinical features

  • Disease is more common in children.
  • Knee joint is the most commonly affected joint.
  • Other joint which are affected are hip, shoulder and elbow. The child is toxic with fever, tachycardia, tachypnea.
  • There is severe pain, swelling, and redness over the joint. Movements are severely restricted and the joint is held in the position of ease. Weight bearing on limb is not possible.

Identify the condition as shown:


NEET PG Jan-2019
A. Brodie abscess
B. Osteoid osteoma
C. Intracortical hemangioma
D. Chondromyxoid fibroma
Correct Ans: Select

Answer. A. Brodie abscess

  • Brodie abscess is an intraosseous abscess related to a focus of subacute pyogenic osteomyelitis.
  • Unfortunately, there is no reliable way radiographically to exclude a focus of osteomyelitis.
  • It has a protean radiographic appearance and can occur at any location and in a patient of any age.
  • It might or might not be expansile, have a sclerotic or nonsclerotic border, or have associated periostitis.


  • Typically these present in children with unfused epiphyseal plates, more frequently in boys.


It has a predilection for ends (metaphysis) of tubular bones:

  1. proximal/distal tibial metaphysis (most common)
  2. carpal and tarsal bones
  3. Rarely traversing the open growth plate; epiphysis (in children and infants).

Radiographic features

Plain radiograph

  • lytic lesion often in an oval configuration that is oriented along the long axis of the bone
  • surrounded by a thick dense rim of reactive sclerosis that fades imperceptibly into surrounding bone
  • lucent tortuous channel extending toward growth plate prior to physeal closure (pathognomonic)
  • periosteal new-bone formation +/- adjacent soft-tissue swelling


Foot drop is caused by injury to which nerve involvement:

NEET PG Jan-2019
A. Femoral nerve
B. Tibial nerve
C. Common peroneal nerve
D. Sciatic nerve
Correct Ans: C

Answer. C. Common Peroneal Nerve

  • Foot drop, sometimes called drop foot, is a general term for difficulty lifting the front part of the foot.


  • Foot drop is caused by weakness or paralysis of the muscles involved in lifting the front part of the foot.
  • Causes of foot drop might include:
  1. Nerve injury. The most common cause of foot drop is compression of a nerve in your leg that controls the muscles involved in lifting the foot (peroneal nerve). This nerve can also be injured during hip or knee replacement surgery, which may cause foot drop.
  2. A nerve root injury — “pinched nerve” — in the spine can also cause foot drop. People who have diabetes are more susceptible to nerve disorders, which are associated with foot drop.
  3. Muscle or nerve disorders. Various forms of muscular dystrophy, an inherited disease that causes progressive muscle weakness, can contribute to foot drop. So can other disorders, such as polio or Charcot-Marie-Tooth disease.
  4. Brain and spinal cord disorders. Disorders that affect the spinal cord or brain — such as amyotrophic lateral sclerosis (ALS), multiple sclerosis or stroke — may cause foot drop.


True about Tenosynovitis of finger ?
NEET PG Jan-2019
A. Fingers held in mild extension / Extension deformity at the involved fingers
B. Tenosynovitis of little finger will spread to thumb rather than ring finger
C. With involvement of little finger the infection can spread to the index finger
D. Treatment is conservative
Correct Ans: B

Ans.B. Tenosynovitis of little finger will spread to thumb rather than ring finger

  • Infection of the synovial sheath that surrounds the flexor tendon

  • Infection from the flexor tendon sheath of the thumb can also extend along the radial bursa to the space of Parona and then into the ulnar bursa and the flexor tendon sheath of the little finger—and vice versa—leading to a “horseshoe” abscess.

  • Horseshoe abscess:

    • May develop from spread pyogenic flexor tenosynovitis, of many individuals have a connection between the sheaths of the thumb and little fingers at the level of the wrist


14 yr old child with Naive Rheumatoid Arthritis patient as shown in image . What should be the correct treatment of given condition:


NEET PG Jan-2019
A. DMARD with short course of Steroids
C. DMARD after initial 3 months of NSAID’S
D. Monotherapy with TNF drugs
Correct Ans: A

Answer A. DMARD with Steroids

Given condition is Rheumatoid Arthritis

  • Rheumatoid arthritis (RA) is a chronic autoimmune multisystemic inflammatory disease which affects many organs but predominantly attacks the synovial tissues and joints.

Clinical features:

  • It occurs between the age of 20 to 50 years.

  • Women are affected about 3 times more commonly than men.

  • Following presentations are common:

a) An acute, symmetrical polyarthritis:

  • Pain and stiffness in multiple joints (at least four)

  • Symptoms of articular inflammation.

  • The joints affected most commonly are the metacarpo- phalangeal joints, particularly that of the index finger.

  • Other joints affected commonly are (given in Table):




MP joints of hand

• PIP joints of fingers

• Wrists, knees, elbows, ankles

Less common

• Hip joint        

• Temporomandibular joint


Atlantoaxial joint

• Facet joints of cervical spine

On examination:

  • Swollen boggy joints as a result of intra-articular effusion, synovial hypertrophy and oedema of the periarticular structures.

  • The joints may be deformed.

Deformities in Rheumatoid arthritis




• Ulnar drift of the hand

Boutonniere deformity

• Swan neck deformity


• Flexion deformity


• Early – flexion deformity

Late – triple* subluxation


• Equinus deformity


• Hallux valgus, Hammer toe, etc.


Treatment and prognosis

  • Treatment of RA is aimed at improving the symptoms and slowing disease progression.

  • Therapy is with a combination of corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs), disease modifying anti-rheumatic drugs (DMARDs), and TNF antagonists (e.g. etanercept).
