Disease and conditions
This section discusses various disease conditions. Click the read more button to continue reading the session.
Otorrhea
Otorrhea is ear drainage that may be purulent, bloody, serous, or serosanguineous, often caused by infections, trauma, neoplasms, or external/middle ear disorders. Careful history, physical examination, and hearing assessment guide diagnosis and management, with pediatric considerations for anatomy and safety.
Papular rash
A papular rash is a cluster of small, solid, raised lesions (<1 cm) that may be red, purple, or flesh-colored, arising from allergic, infectious, autoimmune, drug-related, or neoplastic conditions. Diagnosis relies on history, physical exam, and identifying underlying causes; treatment targets the etiology and may include antipruritic, antihistamine, or antibiotic therapy.
Priapism
Priapism is a persistent, painful penile erection unrelated to sexual activity, often caused by blood disorders, spinal cord injury, drugs, or penile cancer, and constitutes a urologic emergency. Management focuses on prompt pain relief, decompression of the corpora cavernosa, addressing underlying causes, and patient education to prevent complications.
Nonreactive (fixed) pupils
Nonreactive (fixed) pupils fail to constrict or dilate in response to light, indicating possible life-threatening emergencies such as brain herniation, oculomotor nerve palsy, or severe ocular disease. Prompt assessment of cranial nerve function, intracranial pressure, and ocular status is critical for timely intervention.
Jaundice (Icterus)
Jaundice is yellow discoloration of skin, sclera, or mucous membranes due to elevated bilirubin from prehepatic, hepatic, or posthepatic causes. Diagnosis relies on history, physical examination, laboratory tests, and imaging, while management addresses the underlying cause, pruritus, and complications.

Anxiety
Anxiety is a common psychiatric symptom characterized by feelings of uneasiness or dread, ranging from mild discomfort to severe, life-threatening conditions. It can result from physical illness, psychological disorders, or external factors, and requires careful evaluation to identify underlying causes and provide appropriate management.
Peau d’orange
Peau d’orange is the thickened, pitted appearance of breast skin resembling an orange peel, typically indicating advanced breast cancer. It can also occur with breast or axillary infections, and careful history, breast examination, and evaluation of axillary lymph nodes are essential for diagnosis and management.
Extensor thrust reflex
Extensor thrust reflex is a primitive reflex in neonates where leg extension follows sole stimulation, mediated at the spinal cord level. Normally disappears by 6 months; persistence beyond this age suggests anoxic brain damage, and its reappearance in older children indicates central nervous system injury.
Homans’ Sign (Deep Calf Pain on Ankle Dorsiflexion)
Homans’ sign is elicited when abrupt dorsiflexion of the ankle causes deep calf pain, suggesting possible deep vein thrombosis or calf inflammation. However, it is an unreliable indicator and must be interpreted alongside clinical history, physical findings, and diagnostic tests.
Orthopnea
Orthopnea is difficulty breathing while lying flat, often relieved by sitting upright or using pillows, commonly indicating cardiopulmonary disorders such as left-sided heart failure or COPD. Its severity and associated signs guide evaluation, treatment, and monitoring, including oxygen therapy, diuretics, and positional adjustments.
Vaginal discharge
Vaginal discharge varies physiologically with age, menstrual cycle, and estrogen status, but changes in color, odor, consistency, or quantity may indicate infection, sexually transmitted disease, reproductive tract pathology, or malignancy. Assessment includes detailed history, physical and pelvic examination, laboratory testing, and patient counseling on hygiene, medication adherence, and safe sexual practices.
Visual floaters
Visual floaters are moving particles in the vitreous that appear as spots or dots in the visual field. Sudden onset may indicate retinal detachment, vitreous hemorrhage, or posterior uveitis, requiring urgent ophthalmologic evaluation and careful patient management to prevent vision loss.
Agnosia
Agnosia is the inability to recognize or interpret sensory stimuli despite intact primary sensation, caused by lesions in sensory association areas of the parietal cortex. Subtypes include visual, auditory, tactile (astereognosis), gustatory, olfactory (anosmia), autotopagnosia, and anosognosia, commonly following stroke.
Hyperpnea (Increased Respiratory Effort)
Hyperpnea is sustained deep or rapid breathing caused by metabolic, neurologic, or respiratory disorders and may be compensatory, as in Kussmaul’s respirations. Prompt evaluation is essential to identify underlying causes such as acidosis, hypoxemia, or brain injury and to prevent life-threatening complications.
Intermittent claudication
Intermittent claudication is exercise-induced limb pain relieved by short rest, commonly caused by arterial occlusive disease or neurogenic compression. Diagnosis relies on history, physical examination, pulse assessment, and imaging, with management focusing on risk factor modification, exercise, and, in severe cases, revascularization.
Paralysis
Paralysis is the complete loss of voluntary motor function, caused by central or peripheral nervous system injury, degenerative disease, trauma, infection, or toxins, and may be acute, chronic, localized, or generalized. Management involves emergency stabilization for acute cases, thorough neurologic assessment, prevention of complications from immobility, supportive care, and addressing the underlying cause through medical, surgical, or rehabilitative interventions.
Cloudy/turbid urine
Cloudy or turbid urine usually signals urinary tract infection but may also result from mucus, cells, crystals, or specimen deterioration. Diagnosis relies on urinalysis and culture, with treatment focused on the underlying cause, adequate hydration, and patient education on hygiene and therapy adherence.
Bounding pulse
A bounding pulse is a strong, forceful pulsation that can occur normally with exercise, pregnancy, or anxiety but may also signal fever, thyrotoxicosis, aortic insufficiency, or acute alcoholism. Assessment focuses on vital signs, cardiac rhythm, and identifying underlying metabolic or cardiovascular causes.

Hypertensive urgency
Hypertensive urgency is severe hypertension (SBP above 180 mmHg and/or DBP above 110 mmHg) without target organ damage such as pulmonary oedema, cardiac ischaemia, neurological deficit or acute renal failure. Treat in hospital and lower the DBP slowly to about 100 mmHg over 48–72 hours with two or more oral agents.
