Point mutation
|
Frame shift mutation

|
Answer- c- point mutation.Sickle-cell anemia is caused by a point mutation in the b-globin chain of hemoglobin, causing the hydrophilic amino acid glutamic acid to be replaced with the hydrophobic amino acid valine at the sixth position.It is caused by a point mutation (Base substitution mutation) at the sixth position of the b-globin chain leading to subsitution of a valine residue for a glutamic acid residue resulting in sickle hemoglobin (HbS).Sickle cell anemia is an autosomal recessive disorder.

Dent's disease :
Dent's disease, a familial proximal tubular syndrome, is an X-linked recessive disorder of proximal tubules characterized by :
Hypercalciuria and nephrocalcinosis and nephrolithiasis.
Low-molecular-weight proteinuria.
Metabolic bone disease/Rickets.
Progressive renal failure.
Marked inale predominance.
In addition to above features, other renal proximal tubular defect can cause:
(i) Fanconi syndrome (Aminoaciduria, proteinuria, phosphaturia).
(i) Glycosuria, uricosuria and kalliuresis.
(iii) Impaired urinary acidification.
Dent's disease occurs due to mutations that inactivate a voltage-gated chloride transporter, CLC-.5. In some cases, it is associated with mutations in the OCRL-1 gene that is also mutated in the oculocerebral syndrome of Lowe. Coming back to question.
Dent's disease is an X-linked renal tubular disorder.
X-linked disease cannot be transmitted from male to male i.e., from father to son.

Antenatal corticosteroids are given in pre-term (pre-mature) pregnancies not in term pregnancies. Further, antenatal corticosteroids are given to prevent RDS (HMD) --> after antenatal corticosteroids administration, risk of HMD is reduced.
Respiratory distress occurs within first 6 hours.
HMD occurs in pre-term neonate.

Ans: A. PCRReverse transcription-polymerase chain reaction (-PCR) It is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR).It is primarily used to measure the amount of a specific RNA. This is achieved by monitoring the amplification reaction using fluorescence, a technique called real-time PCR or quantitative PCR (qPCR). Combined -PCR and qPCR are routinely used for the analysis of gene expression and quantification of viral RNA in research and clinical settings.A method used to quantitate mRNA levels that rely upon the first step of cDNA copying of mRNAs catalyzed by reverse transcriptase before PCR amplification and quantitation. Sanger sequencing,Also known as the chain termination method, is a technique for DNA sequencing-based upon the selective incorporation of chain-terminating dideoxynucleotides (ddNTPs) by DNA polymerase during in vitro DNA replication.Next-generation sequencing:Modified methods of genome sequencing. It has significantly reduced the cost and time taken for whole-genome sequencing.It is a technique similar to Sanger sequencing, done on DNA

Answer- D- IgEWhen someone has allergies, their immune system makes an antibody called immunoglobulin E (IgE). These antibodies respond to allergens. The symptoms that result are an allergic reaction.IgE also has an essential role in type I hypersensitivity, which manifests in various allergic diseases, such as allergic asthma, most types of sinusitis, allergic rhinitis, food allergies, and specific types of chronic uicaria and atopic dermatitis.

Trigeminal nerve is the 5th cranial nerve. It is a mixed nerve containing both the motor and sensory fibres but predominantly it is sensory.
It is a motor nerve to the muscles of mastication and several small muscles and the principal sensory nerve of the head and face.
It consists of three large nerves: ophthalmic, maxillary, and mandibular, hence the name trigeminal nerve (L. trigeminus = triplet).
Key concept:
Mandibular nerve supplies muscles of mastication mylohyoid, anterior belly of digastric, and tensor tympani.
Posterior belly of digastric and stapedius are supplied by Facial nerve.

Pegloticase - It is recombinant uricase, an enzyme which oxidises uric acid to highly soluble allantoin, that is easily excreted by kidney. Humans lack this enzyme. In this preparation, the enzyme has been coupled with methoxy polyethylene glycol (mPEG) which serves to prolong its sojourn in the body, permitting i.v. infusion of the drug to be given every 2 weeks. It is indicated only in rare cases of refractory symptomatic gout because it is immunogenic and carries high risk of infusion reactions, including anaphylaxis.

Cytomegalovirus (CMV) is transmitted post solid organ transplantation whereas herpes simplex virus (HSV) is transmitted post solid organ transplantation only within a month. Epstein-Barr virus (EBV) is a glandular disease so transmitted by close contact where as human papilloma virus (HPV) is transmitted through sexual contact since it is a sexually transmitted disease. So first option is a better option. Infection in Children: Primary infections in older children and adults are usually asymptomatic. However, a heterophile, antibody-negative, infectious mononucleosis may been. This is more common following transfusion of CMV-infected blood (post - transfusion mononucleosis).

Important points:
––Seen mainly in children and young adult Q
––It is secondary to pulmonary tuberculosis. Q
––Route of spread - Mainly through eustachian tube (not blood borne). Q
Symptoms:
1. Patients often present with chronic painless otorrhoea (usually foul smelling) which is resistant to antibiotic treatment Q
3. Severe conductive type hearing loss Q. (sometimes due to involvement of labyrinth may be SNHL)
4. Facial nerve palsy may be the presenting symptom in childrenQ
5. Cough; fever and night sweats may be present in patients with tuberculous infection in other organ system.
O/E
–– Multiple perforationsQ in tympanic membrane (This feature was once considered characteristic of TB but now is seldom seen).
–– Middle ear and mastoid are filled with pale granulation tissueQ (It is a characteristic of tuberculous otitis media)

Ans: C. Microdebrider(Ref: Scott-Brown's 7Ie p3576; Cummings Pediatric Otolaryngology By Marci M. Lesperance, Paul W. Flint/p51; Dhingra 6/e p430)All these four instruments are used in different techniques of tonsillectomy.Microdebrider is less commonly used than others as it leaves behind a small amount of tissue covering theconstrictor muscle.Hence, preferred answer would be microdebrider.
