Antibiotic of choice in odontogenic space infection
1) Narrow spectrum
2) Broad spectrum
3) Antimycotic
4) Bacteriostatic
Focal segmental glomerulonephritis (FSGS) is the most common primary cause of nephrotic syndrome in adults, while minimal change disease is the most common cause in children.
Most common cause of nephrotic syndrome in adults:
1) Minimal change disease
2) Membrane proliferative glomerulonephritis
3) Focal segmental glomerulonephritis
4) Diffuse glomerulonephritis
The Curve of Wilson is a concept in dental occlusion that refers to the mediolateral curve of the occlusal plane. It is concave in the mandibular arch and convex in the maxillary arch, which helps to align the teeth in the transverse plane.
True about curve of wilson
1). help to align posterior teeth along the long axis of master
2). Align the posterior teeth along the anteroposterior curve
3). Helps to align teeth in transverse plane
4). Align each Teeth to maximum resistance to function loading permits protrusive disocclusion of posterior teeth
Early loss of a primary second molar can result in mesial migration of permanent
molars. If the first permanent molar has already erupted (usually erupts between
6 and 7 years). band-and-loop is recommended.
A distal shoe is an appropriate choice if permanent molar has not fully erupted
Nance appliance is a removable appliance that can be used to prevent mesial movement or tipping of the permanent first molar but has a main disadvantage that it is removable.
If a 7-year-old patient presents with early loss of Tooth A. maxillary right
second primary molar, what is the appropriate space maintainer that can be used?
1) Nance appliance
2) Distal shoe
3) Band-and-loop
4) Lower lingual arch
Lymphoma, specifically non-Hodgkin lymphoma, is a common malignancy associated with HIV/AIDS. Kaposi's sarcoma is also highly prevalent.
Most common tumor seen in HIV:
1) Lymphoma
2) Adenocarcinoma
3) Multiple myeloma
4) Fibroma
Crohn/s disease is a type of inflammatory bowel disease (IBD) that can affect any part of the gastrointestinal tract from mouth to anus. A key pathological feature of Crohn/s disease is the presence of non-caseating granulomas (collections of inflammatory cells) in the affected tissue. These granulomas are not typically found in ulcerative colitis, the other major type of IBD.
Which of the following is true about crohn/s disease
1) Warthim finkeldy giant cells
2) Non caseating granuloma
3) Touton giant cells
4) Oral melanosis
A Self corrective anomaly in a 10 year old child is
1) Anterior cross bite
2) Buccoversion of Mandibular 1st molar
3) Anterior open bite
4) Flaring of incisors
Correct Answer: 2) Myophosphorylase
The child most likely has McArdle disease (Glycogen Storage Disease Type V), which is caused by deficiency of muscle glycogen phosphorylase (myophosphorylase). The enzyme deficiency prevents breakdown of glycogen in skeletal muscle during exercise, leading to exercise intolerance, painful muscle cramps, fatigue and myoglobinuria in severe cases. Blood lactate fails to rise after exercise, while the second-wind phenomenon may be observed.
Why other options are incorrect:
1) G-6-phosphatase deficiency causes Von Gierke disease with severe fasting hypoglycaemia.
3) Debranching enzyme deficiency causes Cori disease (GSD III).
4) Glycogen synthase deficiency causes Glycogen Storage Disease Type 0.
NEET MDS Key Point: McArdle disease = Myophosphorylase deficiency = Exercise-induced muscle cramps + myoglobinuria + normal blood glucose.
An 8-year-old child complains of repeated cramping of calf muscles after physical exertion in school. This condition has been been present for the last few years. He was diagnosed with a disorder of glycogen metabolism. Which enzyme deficiency is most likely present?
1) G-6-Phosphatase
2) Myophosphorylase
3) Debranching enzyme
4) Glycogen synthase
The functional occlusal plane is used as the reference in the transverse direction for the WITS analysis to assess the sagittal jaw relationship.
Plane of reference used in transverse direction in WITS analysis
1) Frankfort horizontal plane
2) Sella nasion plane
3) Functional occlusal plane
4) Palatal plane
