Q: Altered sensation over the area of the great saphenous vein in the leg is seen due to an injury to which of the following nerves?

Femoral. ***Femoral*** - The **femoral nerve** gives rise to the **saphenous nerve**, which runs with the great saphenous vein and provides sensation to the medial aspect of the leg and foot. - Injury to the femoral nerve or its saphenous branch can result in altered sensation in the distribution of the **great saphenous vein**. *Tibial* - The **tibial nerve** innervates muscles in the posterior compartment of the leg and provides sensation to the sole of the foot and parts of the ankle, not the area of the great saphenous vein. - Injury to the tibial nerve often leads to **motor deficits** (plantar flexion) and sensory loss on the bottom of the foot. *Sural* - The **sural nerve** provides sensation to the posterolateral aspect of the leg and the lateral side of the foot, distinct from the great saphenous vein's territory. - This nerve is often injured during procedures around the **lateral malleolus** or Achilles tendon. *Fibular* - The **fibular nerve** (also known as the common peroneal nerve) innervates the anterior and lateral compartments of the leg and provides sensation to the dorsum of the foot and lateral leg. - Injury typically results in **foot drop** and sensory loss **dorsum of foot**.

Q: A 50-year-old man with carcinoma of the prostate presents with X-ray findings showing sclerosis and collapse of T10 and T11 vertebrae. The spread of cancer to these vertebrae most probably occurred through which route?

Internal vertebral plexus of veins (Batson's plexus). ***Internal vertebral plexus of veins (Batson's plexus)*** - The **Batson's plexus** is a valveless network of veins directly connecting the pelvic venous plexuses (including those draining the prostate) with the vertebral venous system. - This valveless nature allows for easy retrograde flow of tumor cells, especially during increases in intra-abdominal pressure (e.g., coughing, straining), facilitating direct spread from the prostate to the vertebrae. *Spread through the sacral canal to the vertebrae* - While the sacral canal contains structures, it is a bony canal and not a primary route for direct hematogenous or lymphatic metastatic spread of prostate cancer to the vertebral bodies. - Metastasis through the sacral canal itself would typically imply direct extension or invasion, which is less common for widespread vertebral metastases than venous dissemination. *Spread via superior rectal veins to the vertebrae* - The **superior rectal veins** drain into the inferior mesenteric vein, which is part of the portal system, eventually leading to the hepatic circulation. - While this route can lead to liver metastases, it generally does not directly connect to the vertebral venous system in a way that would explain isolated vertebral metastases without liver involvement. *Spread through lymphatic vessels to the vertebrae* - Lymphatic spread from prostate cancer typically involves regional **pelvic lymph nodes** first (e.g., obturator, internal iliac, presacral). - While lymphatic spread can occur, it usually precedes or accompanies distant metastases and is less likely to be the sole, direct route for vertebral involvement without evident lymphadenopathy in the direct path.

Q: Uncontrolled diabetes poses a problem to a prosthodontist as

more bone resorption. ***more bone resorption*** - Uncontrolled diabetes *impairs bone metabolism and regeneration*, leading to increased **osteoclastic activity** and reduced osteoblastic function, which results in *greater bone loss*. - This heightened bone resorption makes it difficult to achieve **stable denture retention** and can compromise the success of *dental implants* and other prosthodontic treatments. *increased salivary flow* - Diabetes often causes **xerostomia** (dry mouth) due to *reduced salivary gland function*, not increased salivary flow. - Reduced salivary flow impacts *denture retention, lubrication, and oral hygiene*, making it a further challenge for prosthodontists. *less bone resorption* - This statement is incorrect; uncontrolled diabetes is associated with *increased, not decreased, bone resorption*. - **Hyperglycemia** negatively affects bone health through various mechanisms, including advanced glycation end-products (AGEs) formation and systemic inflammation. *increased tissue laxity* - While diabetes can affect connective tissues, the primary and most significant prosthodontic concern regarding bone is **increased bone resorption**, not necessarily generalized tissue laxity that directly impacts denture stability in the same way. - **Poorly controlled diabetes** can lead to issues like reduced wound healing and increased susceptibility to infection, which are also relevant, but bone resorption is a more direct mechanical issue for prosthodontics.

Q: All are true regarding oral hairy leukoplakia except which of the following?

It is premalignant. ***It is premalignant*** - Oral hairy leukoplakia is associated with **Epstein-Barr virus (EBV)** and is not considered a precancerous condition [1]. - This condition is primarily seen in immunocompromised individuals and does not progress to malignancy [1]. *Hyperkeratosis on HPE* - Histopathological examination typically reveals **keratinized epithelial layers** but is not characterized by prominent hyperkeratosis. - Rather, it shows **ballooning degeneration** of epithelial cells rather than classic hyperkeratotic features [1]. *Associated with EBV infection* - Oral hairy leukoplakia is strongly associated with **EBV**, particularly in immunocompromised patients [1]. - It manifests as white plaques on the lateral borders of the tongue due to **viral replication** of EBV-infected epithelial cells [1]. *Seen in HIV infected patients* - This condition is commonly seen in **HIV-infected individuals**, particularly those with a low CD4 count [1]. - It serves as a clinical marker for **immunosuppression** but is not exclusive to HIV [1]. **References:** [1] Kumar V, Abbas AK, et al..
