This patient presents with panic-like somatic symptoms triggered by bereavement. Normal investigations rule out cardiac pathology. Grief therapy is appropriate as the underlying stressor is unresolved grief and anxiety.

Toronto Notes 2023 – Psychiatry, Grief and Anxiety Disorders:

“Bereavement-related anxiety and somatization are common. Grief counseling can help reduce somatic and psychological symptoms when medical causes are ruled out.”

MCCQE1 Objectives – Psychiatry > Anxiety and Bereavement:

“Candidates should recognize psychological sequelae of grief, including panic and health anxiety, and provide appropriate psychological support.”

Metoprolol (C) is not indicated without confirmed cardiac cause. Lorazepam (B) may offer short-term relief but does not address the underlying grief. Stress testing (A) is unnecessary with repeated normal investigations.

====================================================

The presence of suicidal ideation in a minor mandates urgent assessment to ensure safety and access mental health care. Disclosure of sexual orientation should be handled delicately and is not urgent compared to suicidal risk.

Toronto Notes 2023 – Psychiatry, “Child and Adolescent Psychiatry” Section:

“Any adolescent disclosing suicidal ideation should be referred for urgent mental health evaluation. Concurrent issues such as sexual orientation may contribute to distress and should be addressed with appropriate support over time.”

MCCQE1 Objectives (Psychiatry > 79-2: Suicide Risk Assessment):

“Candidates must immediately refer for psychiatric assessment when a minor reports suicidal ideation, regardless of other social or developmental concerns.”

Antidepressants (A) may be appropriate but must follow specialist evaluation. Encouraging disclosure (B) or peer groups (C) is premature without ensuring safety.

Dog bites from animals of unknown rabies status, especially from endemic regions and in patients with uncertain immunization status, require immediate post-exposure prophylaxis (PEP) including both rabies immunoglobulin and vaccine. The decision is urgent given the fatal nature of rabies.

Toronto Notes 2023 – Infectious Diseases, “Rabies Exposure”:

“Rabies PEP is indicated for bites from animals with unknown vaccination status or those showing abnormal behavior, particularly in endemic regions. PEP includes both vaccine and immunoglobulin.”

MCCQE1 Objectives (Public Health > 64-1: Rabies and Animal Bites):

“Candidates must recognize indications for rabies post-exposure prophylaxis.”

Ciprofloxacin (C) is not the antibiotic of choice (amoxicillin-clavulanate is preferred). Hydrogen peroxide (E) can be cytotoxic. Debridement (B) and CK (D) are not immediate priorities here.

Comprehensive and Detailed Explanation:

Physicians must avoid conflicts of interest and maintain professional boundaries with patients and their families. Accepting a personal financial gift, regardless of intent, is inappropriate and unethical.

Toronto Notes 2023 – Ethics and Professionalism:

“Personal gifts of significant value from patients or families should be declined to avoid real or perceived conflicts of interest.”

MCCQE1 Objectives (ELOM > 90-3: Professionalism and Boundaries):

“Candidates must maintain ethical boundaries and refuse financial incentives that could compromise or appear to compromise clinical judgment.”

Other options (A, B, E) still involve a conflict. D is helpful, but the ethical obligation is to decline the cheque directly.

This case suggests diversion of prescription opioids, a serious safety and regulatory concern. The physician must balance maintaining patient care with minimizing risk. Daily dispensing via a monitored pharmacy is the safest and most practical solution to prevent misuse or theft, while avoiding immediate discontinuation of the patient’s needed medication.

Toronto Notes 2023 – Chronic Pain & Substance Use:

“In cases of concern for opioid diversion, consider witnessed daily dispensing, prescription monitoring, and involving caregivers when appropriate.”

MCCQE1 Objectives (Internal Medicine > Pain Management > 56-2):

“The candidate must demonstrate understanding of strategies for safe prescribing and monitoring of controlled substances, including mitigation of diversion.”

Calling the police (A) is not the physician’s immediate duty. Providing an early refill (B) worsens risk. Tapering (C) may be appropriate later, but first the medication must be safeguarded. Increasing quantity (D) is inappropriate.

====================================================

This case describes classic signs of delusional parasitosis (also known as Morgellons syndrome).However, the presence of widespread crusted lesions raises suspicion for crusted scabies, particularly in older adults. Crusted scabies may be misinterpreted as chronic dermatitis or psychocutaneous disorder. The most effective treatment is oral ivermectin.

Toronto Notes 2023 – Dermatology:

“Crusted scabies presents as widespread hyperkeratotic plaques with crusting. First-line treatment is oral ivermectin, often with topical permethrin.”

MCCQE1 Objectives (Medicine > Dermatology > 23-1):

“Candidates must recognize presentations of ectoparasitic infections, including scabies, and provide appropriate treatment.”

Permethrin (B) is for typical scabies, but crusted scabies often requires systemic ivermectin due to severity and spread.

====================================================

The presentation is consistent with rotator cuff tendinopathy or subacromial impingement. The painful arc between 30°–120° with preserved passive ROM suggests this. Ultrasound is the preferred initial imaging modality due to its availability, safety, and ability to visualize soft tissues dynamically.

Toronto Notes 2023 – Orthopedics, “Shoulder Pathologies” Section:

“In rotator cuff injuries or impingement syndromes, initial imaging with musculoskeletal ultrasound is appropriate. It can identify tendinopathy, partial tears, or subacromial bursitis.”

MCCQE1 Objectives (Surgery > 84-7: Musculoskeletal Pain):

“Candidates should initiate workup for rotator cuff or impingement syndromes with ultrasound as the first-line test, reserving more invasive or costly procedures for unresolved or complex cases.”

CT (A) is used for bony detail, not soft tissues. Arthroscopy (C) is invasive and therapeutic. Arthrography (D) is outdated and largely replaced by MRI or ultrasound.

====================================================

A limited vocabulary (fewer than 50 words by age 2–3 years) and reduced social interaction (limited interest in peers) raise concern for autism spectrum disorder (ASD). Screening for ASD is the most appropriate next step.

Toronto Notes 2023 – Pediatrics, Development and Behaviour:

“Red flags for autism include delayed language, limited social reciprocity, and poor peer interaction. Screening should be initiated early when clinical signs are present.”

MCCQE1 Objectives – Pediatrics > Developmental Disorders:

“Candidates must identify key signs of ASD and initiate appropriate screening and early intervention.”

Multilingual households do not typically cause such delays (E is incorrect). ADHD (B) presents with attention/hyperactivity issues, not language/social delay. Reassurance (A) is inappropriate. Neurology referral (C) may follow but is not first-line.

====================================================

When encountering vaccine hesitancy, the first and most effective step is to open a non-judgmental conversation and explore the patient’s reasons. This helps build trust and tailor subsequent education and counseling.

Toronto Notes 2023 – Public Health and Preventive Medicine, Immunization:

“Addressing vaccine hesitancy requires understanding parental concerns. Begin with open-ended questions to identify underlying beliefs and information gaps.”

MCCQE1 Objectives – Preventive Medicine > Immunization:

“Candidates must demonstrate effective communication with vaccine-hesitant parents, beginning with eliciting their rationale before providing evidence-based recommendations.”

Jumping to education (B) or punitive measures (C, D) may close communication. The patient is an adult; speaking with her parents (E) violates her autonomy.

====================================================

The clinical picture suggests an obstructive anomaly of the female reproductive tract, such as imperforate hymen or vaginal outflow tract obstruction, leading to hematocolpos. The first essential step is physical examination of the external genitalia.

Toronto Notes 2023 – Pediatrics and Gynecology, “Amenorrhea” Section:

“In girls with primary amenorrhea and cyclic abdominal pain, perform an external genital exam to rule out obstructive anomalies (e.g., imperforate hymen or transverse vaginal septum). Examination should always precede imaging.”

MCCQE1 Objectives (Pediatrics > 78-3: Puberty and Menstrual Disorders):

“Candidates must evaluate delayed menarche with physical exam, including inspection of the genitalia to rule out anatomic obstruction.”

Pelvic ultrasound (D) is helpful but should follow physical exam. Radiography (B), hCG (C), and urinalysis (E) are not primary steps in evaluating amenorrhea with a mass.
