Case Based Learning for April 2025

Shoulder dislocation HPI: 20 yo otherwise healthy individual presents to you with acute left upper arm pain. The patient reports that they were mountain-bike riding, lost control of their bike and crashed. They are not sure how they landed but report immediate pain and numbness in their left upper extremity post-crash. Patient is concerned since they cannot move their upper arm and report it feels numb over the lateral aspect of their shoulder. They were able to ambulate into your emergency department and deny other injuries. They deny prior UE trauma, chronic joint pains, illnesses, or systemic symptoms.   Question 1: Based on your knowledge of anatomy, describe some potential causes of traumatic upper arm pain. Common causes of acute traumatic upper arm pain include humeral fracture, clavicular fracture, Acromioclavicular (AC) joint separation, glenohumeral dislocation, rotator cuff tear.   Question 2: What is the typical mechanism of injury for each of the above potential items? Think about the anatomy and how it might be disrupted. Proximal Humeral Fracture: Most often are caused by a fall or direct blow to the lateral shoulder. Type of fracture is determined by the body and arm position when the direct force is applied. (i.e., outstretched vs adducted arm) Clavicular Fracture: Often occurs with a fall onto a shoulder or being stuck over the clavicle with a heavy object. AC separation: Typically occurs from direct trauma to the superior or lateral aspect of the shoulder with the arm adducted Glenohumeral dislocation: An anterior shoulder dislocation is usually caused by a blow to the abducted, externally rotated, and extended arm. Examples would be fall on an outstretched arm, blocking a basketball shot, or blow to the posterior humerus. Rotator cuff tear: Most rotator cuff tears are seen in the middle aged or older adults and are…

Case Report: Acute Angle-Closure Glaucoma in a 43-Year-Old Male

Introduction Acute angle-closure glaucoma (AACG) is an ocular emergency resulting from a rapid increase in intraocular pressure (IOP) due to obstructed aqueous humor outflow. It is commonly associated with a shallow anterior chamber angle, predisposing individuals to blockage. Without timely intervention, AACG can lead to permanent vision loss or blindness. This report describes the presentation, diagnosis, and management of AACG in a patient presenting to the emergency room (ER). Patient Presentation A 43-year-old male with no significant past medical history presented to the ER on a Sunday afternoon with blurred vision and pain in the right eye that began the day before. He initially hoped the symptoms would resolve on their own but sought medical attention after consulting a healthcare provider. He reported a sharp, constant headache behind the right eye rated 6/10, accompanied by nausea and blurred vision, described as though a film was over the right eye. He also noticed mild redness in the right eye but denied discharge, pain with eye movement, photophobia, fever, chills, respiratory, gastrointestinal, or genitourinary symptoms. Physical Examination Vital Signs: T 98.7°F, P 85 bpm, R 16/min, BP 151/87 mmHg, SpO₂ 97% on room air.Visual Acuity: Right Eye 20/40, Left Eye 20/20. Extraocular Movements (EOM): Full range of motion without pain. External Eye Exam: Eyelids everted—no foreign bodies. Mild conjunctival erythema, no discharge. Corneal Staining: Fluorescein stain showed no corneal uptake. Funduscopic Exam: Right Eye: Cloudy cornea, retina not visualized. Left Eye: Retina visualized, no gross abnormalities. Intraocular Pressure (IOP): Right Eye 76-80 mmHg, Left Eye 14-17 mmHg. Slit Lamp Exam: Not available in the ER. Working Diagnosis Acute Angle-Closure Glaucoma (AACG) Treatment Provided in ER Acetazolamide (Diamox): 500 mg PO (IV formulation unavailable) Timolol 0.5%: 2 drops in the right eye Apraclonidine and Prednisolone ophthalmic solutions were not available. Ophthalmology Consultation: Arranged…

Case-Based Learning, June 2024

81-year-old female presented to the emergency department with complaints of generalized body aches and increasing illness over the past week. She reported fever, nausea, vomiting, and anorexia at home for the previous 8 days. She stated that because of the decreased appetite and nausea with vomiting, she has lost 15 pounds in the past week and a half. She also noted that she has a history of gallstones. On initial examination, she is afebrile. She does not meet SIRS criteria. Blood pressure is 116/73. She had tenderness in the right upper quadrant with palpation. She was administered hydromorphone 0.5 mg IV per pain protocol and morphine 4 mg IV per pain protocol. Workup included CBC, CMP, lactic acid, CRP, sed rate, urinalysis, and nasopharyngeal PCR 4 plex swab. She had both a limited right upper quadrant ultrasound and a CT angiography of the chest, abdomen, and pelvis during her evaluation in the emergency department. White blood cell count was 16.7 with left shift. ESR 94. Sodium 131. Alkaline phosphatase 317. AST 92. A LT 415. Lactic acid 1.3. CRP 36.8. 4 plex swab is negative for COVID-19, influenza, and RSV. Urinalysis with small bilirubin, otherwise normal. Ultrasound demonstrated gallbladder distention with gallbladder wall thickening and cholelithiasis. There also appeared to be an oval shaped structure in the gallbladder lumen that probably represented tumefactive sludge. The overall appearance was concerning for cholecystitis although it is reported that a sonographic Murphy sign was absent per TeleRadia report. CT chest, abdomen, and pelvis demonstrated central lobular emphysema. Cholelithiasis was noted and the gallbladder wall thickness was measured as much as 9 mm. Findings were reported consistent with cholecystitis per TeleRadia report. General surgery was consulted. At the time of the general surgeon’s examination, patient had received IV pain medication and was feeling better…
