Q: Magnan's syndrome is associated with:

Amphetamine. ***Amphetamine*** - **Magnan's syndrome** is a psychotic disorder characterized by **tactile hallucinations** (formication) and delusions of parasitosis, most commonly associated with **chronic amphetamine abuse**. - Users describe a sensation of **small insects crawling under the skin**, often leading to self-mutilation as they try to extract them. *OPC* - **Organophosphate poisoning (OPC)** primarily causes **cholinergic crisis** with symptoms like miosis, lacrimation, salivation, bronchorrhea, and muscle weakness. - It is not typically associated with chronic tactile hallucinations or delusions of parasitosis. *Snake bite* - **Snake bites** can cause a wide range of symptoms depending on the venom type, including localized pain, swelling, tissue necrosis, coagulopathy, and neurological effects. - However, they do not typically lead to the specific pattern of tactile hallucinations and delusions characteristic of Magnan's syndrome. *Alcohol* - Chronic **alcohol abuse** can lead to various psychological and neurological complications, including **alcohol withdrawal delirium (delirium tremens)**, which can involve visual and auditory hallucinations. - While it can manifest with tactile sensations, the classic "bugs crawling" sensation with delusional parasitosis (Magnan's syndrome) is more specifically linked to stimulant abuse, like amphetamines.

Catalepsy. ***Catalepsy*** - Catalepsy refers to a **waxy flexibility** and maintenance of postures seen in **catatonia** (a psychiatric condition). - It is **NOT** part of the classic tetrad of narcolepsy. - The classic tetrad includes **cataplexy** (not catalepsy), which is sudden muscle weakness triggered by strong emotions, along with excessive daytime sleepiness, sleep paralysis, and hypnagogic/hypnopompic hallucinations. *Hypnagogic hallucination* - Vivid, often frightening, dream-like experiences that occur while **falling asleep** (hypnagogic) or upon awakening (hypnopompic). - This is a recognized component of the **classic tetrad of narcolepsy**. *Sleep paralysis* - Temporary inability to move or speak upon **waking up or falling asleep**. - One of the four key symptoms forming the **classic tetrad of narcolepsy**. *Sleep attacks* - Sudden, irresistible urges to sleep that can occur at any time, often without warning. - **Excessive daytime sleepiness** leading to these attacks is a core feature and part of the **classic tetrad of narcolepsy**.

Q: Penile buccal coitus is:

Fellatio. ***Fellatio*** - **Fellatio** specifically refers to oral sex involving stimulation of the penis with the mouth. - The term "buccal coitus" in the context of penile stimulation directly describes the act of fellatio. *Sadism* - **Sadism** is a paraphilia characterized by deriving sexual pleasure from inflicting pain, humiliation, or suffering on others. - It does not describe a specific sexual act involving penile buccal coitus, but rather the motivation behind certain acts. *Fetishism* - **Fetishism** involves sexual attraction to non-genital body parts or inanimate objects. - While oral sex can be a preference, it is not inherently a fetish unless the focus is exclusively or predominantly on the mouth or penis as an isolated object, rather than interpersonal sexual activity. *Cunnilingus* - **Cunnilingus** is a form of oral sex involving stimulation of the vulva or clitoris. - This term describes oral sex directed at female genitalia, not the penis.

Q: Quod hanc means:

Impotent towards a particular woman. ***Impotent towards a particular woman*** - The Latin phrase "**Quod hanc**" translates to "towards this woman." - In a medical or medico-legal context, particularly when discussing impotence or fertility, it refers to a situation where a man is **impotent only in relation to a specific woman** or partner, but not with others. [1] *Impotent due to psychological factors* - While psychological factors can cause situational impotence, "Quod hanc" specifically describes an impotence directed **"towards this woman,"** rather than broadly psychological. - This option is broader than the precise meaning of the Latin phrase, which highlights the **specificity of the partner**. *Impotent due to physical factors* - "Quod hanc" has no direct implication about the underlying cause being physical; it solely points to the **target of the impotence**. - Physical impotence would generally mean an inability to achieve erection with **any partner**, which contradicts the specific nature implied by "hanc." *Impotent in specific situations* - This is a general term for **situational impotence**, which could include performance anxiety or stress. [1] - "Quod hanc" is a **more specific sub-category** of situational impotence, precisely indicating that the impotence is directed at "this woman." [Practice more Psychiatry PYQs on OnCourse]
