Clinical Manifestations and Presentation of Diseases Practice Questions

Q: In a patient there is dyspnea in upright position which is relieved in supine position, Diagnosis ?

Platypnea. ***Platypnea*** - **Platypnea** is defined as **dyspnea that worsens in an upright position** and improves when lying down. - This condition is often associated with **hepatopulmonary syndrome**, **intracardiac shunts** (e.g., patent foramen ovale), or **pulmonary arteriovenous malformations**, where gravity affects blood flow and gas exchange. *Tachypnea* - **Tachypnea** refers to an **abnormally rapid rate of breathing**. - It describes the *rate* of respiration, not its variation with body position. *Orthopnea* - **Orthopnea** is **dyspnea that occurs when lying flat** and is relieved by sitting or standing up [1]. - It is often seen in conditions like **heart failure**, where fluid redistribution to the lungs is exacerbated in the supine position [2]. *Paroxysmal nocturnal dyspnea* - **Paroxysmal nocturnal dyspnea (PND)** is characterized by **sudden, severe shortness of breath at night** that awakens the person from sleep [2]. - It is typically caused by **left-sided heart failure** and is relieved by sitting upright or standing, which is the opposite of the described scenario.

Q: In which condition is Serum Amyloid Associated (SAA) protein most commonly found?

Chronic inflammatory states. ***Chronic inflammatory states*** [1][2] - Serum amyloid-associated protein is elevated in response to **chronic inflammation**, such as in rheumatic diseases and infections [1][2]. - It serves as a **biomarker** indicating systemic inflammation and is part of the **acute-phase response** [1]. *Chronic renal failure* - While renal failure can lead to amyloidosis, it is not a direct cause of serum amyloid-associated protein elevation. - **Renal impairment** is more associated with a decrease in clearance rather than production of amyloid proteins. *Alzheimer's disease* - Although amyloid plaques are a hallmark of Alzheimer's, they are related to **A-beta peptide**, not serum amyloid-associated protein. - Alzheimer's pathology primarily involves **neurodegeneration** rather than inflammatory response. *Malignant hypertension* - Malignant hypertension primarily affects the **vascular system** and does not directly involve the production of serum amyloid-associated protein. - It is characterized by end-organ damage, rather than a state of chronic inflammation. *Chronic inflammatory conditions like RA, TB & leprosy, osteomyelitis, ankylosing spondylitis, IBD, bronchiectasis, some tumors* [1][2] - While these conditions can be associated with systemic inflammation, they are too specific and do not comprehensively encompass the broader concept of **chronic inflammatory states**. - This option fails to highlight that serum amyloid-associated protein is a marker for **various chronic inflammatory states** beyond just those listed [1].

Q: What will the aspirated synovial fluid in a case of septic arthritis typically show?

Markedly increased polymorphonuclear leukocytes. ***Markedly increased polymorphonuclear leukocytes*** - **Septic arthritis** is characterized by an acute infection within the joint, leading to a profound inflammatory response with a significant influx of **neutrophils** (polymorphonuclear leukocytes) into the synovial fluid. - A synovial leukocyte count greater than **50,000 cells/mm³** with over **75% neutrophils** is highly suggestive of septic arthritis. *Clear and straw-colored fluid* - This description typically corresponds to **normal synovial fluid** or fluid from a mild **non-inflammatory condition**, which is not consistent with bacterial infection. - Normal synovial fluid is usually **transparent**, indicating the absence of significant cellular debris or inflammatory cells. *Low viscosity fluid* - While septic synovial fluid can have reduced viscosity due to the breakdown of **hyaluronic acid** by bacterial enzymes and inflammatory mediators, this characteristic alone is not the most definitive diagnostic feature. - Reduced viscosity is also observed in other inflammatory conditions, making it less specific than direct cellular analysis for diagnosing infection. *Cloudy or purulent fluid* - The presence of **cloudy** or **purulent (pus-like)** fluid *is* often seen in septic arthritis, reflecting the high cell count and protein content. - However, this is a **gross visual observation**, and a more precise and diagnostic indicator is the microscopic finding of markedly increased **polymorphonuclear leukocytes**.

Q: Match stick test is positive in ?

Leprosy. ***Leprosy*** - The **matchstick test** is a simple neurological examination used to detect **nerve damage** in leprosy, specifically **sensory loss** [1]. - A positive test indicates the patient cannot perceive the touch or pain from a matchstick, commonly due to damage to superficial nerves caused by *Mycobacterium leprae* [1]. *Rhinophyma* - This condition is characterized by **sebaceous gland hypertrophy** and **fibrosis** of the nose, often associated with rosacea. - It does not involve nerve damage or sensory loss that would be assessed by a matchstick test. *Rhinoscleroma* - Rhinoscleroma is a **chronic granulomatous bacterial infection** of the upper respiratory tract. - While it causes significant tissue destruction and structural changes, it is not primarily associated with the sensory neuropathies that the matchstick test evaluates. *P. vesticolor* - *Pityriasis versicolor* is a **superficial fungal infection** of the skin, causing discolored patches. - This condition is a dermatological issue and does not involve nerve damage or sensory deficits, making the matchstick test irrelevant.

Q: Lovibond profile sign is seen in ?

Nail clubbing. Nail clubbing - The Lovibond profile sign (Lovibond's angle or profile sign) is a clinical finding where the angle between the nail plate and the proximal nail fold straightens or becomes greater than 180 degrees. - This sign is a key indicator of nail clubbing, which is often associated with underlying systemic conditions such as respiratory or cardiac diseases [1]. Koilonychia (spoon nails) - Koilonychia presents as concave or spoon-shaped nails, where the nail plate is depressed centrally with everted edges [1]. - This condition is typically associated with iron deficiency anemia and does not involve an alteration of the Lovibond angle. Platynochia (flat nails) - Platynochia refers to nails that are unusually flat without the normal convex curvature. - This is a descriptive term for nail shape and is not specifically evaluated by the Lovibond profile sign. Onycholysis (separation of the nail from the nail bed) - Onycholysis is the detachment of the nail plate from the nail bed, usually starting at the distal free edge. - This condition is unrelated to the angle of the nail and the nail fold, which are assessed by the Lovibond profile sign.

Q: Acute orchitis is characterized by all of the following except:

Decreased blood flow. ***Decreased blood flow*** - **Acute orchitis** is an inflammatory process that typically leads to increased blood flow (hyperemia) to the affected testis due to the inflammatory response. - Decreased blood flow would be more characteristic of conditions like **testicular torsion**, which is an emergent condition causing ischemia. *Increased local temperature* - **Inflammation** is characterized by the classic signs of rubor (redness) and calor (heat), leading to an **increased local temperature** in the affected area. - This is a common finding in acute orchitis due to the inflammatory response. *Erythematous scrotum* - The inflammatory process in orchitis causes **vasodilation** and increased vascular permeability, leading to redness and swelling of the overlying scrotal skin. - An **erythematous scrotum** is a typical clinical sign of acute orchitis. *Raised TLC* - **TLC (Total Leukocyte Count)** is often elevated in cases of acute infection or inflammation, such as orchitis. - A **raised TLC** indicates a systemic inflammatory response to the infection.

Q: Which of the following is a symptom of protein deficiency?

Flaky paint like skin. ***Flaky paint like skin*** - This dermatological manifestation, known as **"flaky paint" dermatosis** or **crazy pavement dermatosis**, is a classic sign of **severe protein-energy malnutrition** (PEM), particularly **kwashiorkor**. - It results from **altered skin keratinization** and **desquamation** due to inadequate protein synthesis, leading to patches of hyperpigmentation and peeling skin that resemble peeling paint. *Glossitis* - **Glossitis**, or inflammation of the tongue, is primarily associated with deficiencies of **B vitamins** (especially B12, folate, niacin, and riboflavin) and **iron deficiency**. - While protein deficiency can broadly affect cell turnover, glossitis is not a primary or specific symptom directly attributable to it. *Nail change* - Various **nail changes** can indicate nutritional deficiencies, but they are more commonly linked to deficiencies in **iron** (e.g., koilonychia or "spoon nails"), **zinc** (e.g., Beau's lines, white spots), or certain **vitamins**. - While chronic malnutrition can impact nail health, there isn't a specific, characteristic nail change solely indicative of protein deficiency. *Cherry like skin* - "Cherry-like skin" is not a recognized dermatological symptom associated with any specific nutritional deficiency in medical literature. - Skin manifestations like **cherry angiomas** are benign vascular proliferations and are generally not linked to nutritional status.

Q: What is the primary clinical feature of Henoch-Schonlein purpura?

Skin rash characterized by palpable purpura. ***Skin rash characterized by palpable purpura*** - **Palpable purpura** is the hallmark cutaneous manifestation of **Henoch-Schonlein purpura (HSP)**, a small-vessel vasculitis [1]. - This rash typically appears on the **lower extremities and buttocks**, reflecting the deposition of IgA in vessel walls [1]. *Abdominal pain due to vasculitis* - While **abdominal pain** is a common feature of HSP due to gastrointestinal vasculitis, it is not considered the primary clinical feature [1]. - Gastrointestinal involvement can manifest with pain, bleeding, and intussusception, but the **skin rash** is more consistently present and diagnostic. *Joint pain associated with the condition* - **Arthralgia** or **arthritis** (joint pain) is seen in a significant number of HSP patients, particularly in the knees and ankles. - However, it is a secondary manifestation, and not the **defining primary sign** of the disease. *Kidney involvement in the disease* - **Renal involvement**, presenting as hematuria and proteinuria, occurs in about one-third of HSP cases and can lead to serious long-term complications. - Despite its significance for prognosis, **kidney disease** is a later and not universally present feature, making the rash the most critical initial diagnostic clue.

Q: Which of the following is NOT a feature of Peutz-Jeghers syndrome?

Autosomal recessive inheritance. ***High risk of malignancy*** - Peutz-Jeghers syndrome is primarily associated with **benign hamartomatous polyps**, not a **high risk of malignancy**, which distinguishes it from other syndromes. - Although patients may develop cancers [1], the syndrome itself does not inherently denote a high malignancy risk like other syndromes such as familial adenomatous polyposis. *Autosomal dominant* - This syndrome is indeed **autosomal dominant**, caused by mutations in the STK11 gene. - Families with this condition typically show **vertical transmission**, characteristic of autosomal dominant inheritance. *Hamartomatous polyp* - Individuals with Peutz-Jeghers syndrome develop **hamartomatous polyps**, which are a hallmark feature of the condition [1]. - These polyps can occur in the gastrointestinal tract and are benign lesions rather than adenomatous type seen in other syndromes [1]. *Mucocutaneous pigmentation* - Mucocutaneous pigmentation, such as **freckling around the lips and buccal mucosa**, is a key clinical feature of Peutz-Jeghers syndrome. - This pigmentation usually appears in childhood and is often a distinguishing sign of the syndrome.

Q: Which of the following conditions is most commonly associated with resorption of the distal phalanx?

Scleroderma. ***Scleroderma*** - **Scleroderma** (systemic sclerosis) can cause characteristic changes in the distal phalanges, specifically **acro-osteolysis**, leading to resorption of the **distal tufts** [1]. - This is often associated with **Raynaud's phenomenon**, **digital ischemia**, and **calcinosis**, leading to severe circulatory compromise in the digits [1]. *Hyperparathyroidism* - **Primary hyperparathyroidism** causes bone resorption due to increased parathyroid hormone, primarily affecting the **subperiosteal bone** (especially in the radial aspect of the middle phalanges), leading to a "lace-like" appearance on X-ray. - While it causes bone resorption, **distal phalanx tuft resorption** is not its most common or prominent skeletal feature compared to scleroderma. *Reiter's syndrome* - **Reiter's syndrome** (now known as reactive arthritis) is an inflammatory arthropathy usually involving large joints of the lower extremities in an **asymmetric** pattern. - It does not typically cause **resorption of the distal phalanx**; instead, it's associated with enthesitis, dactylitis, and periostitis. *Osteitis deformans (Paget's disease)* - **Paget's disease** is characterized by abnormal bone remodeling, leading to enlarged, deformed bones that are prone to fracture, predominantly affecting the **pelvis, spine, skull, and long bones**. - It causes areas of localized bone destruction and excessive bone formation, but **distal phalanx resorption** is not a feature of this condition.
