Neurology

An 80-year-old man with a history of congestive heart failure, coronary artery disease, cardiomyopathy, and thoracic and abdominal aneurysms was taken to the emergency department because of mental status changes, back pain, and ecchymotic areas over his body. The ecchymoses started on his back 5 days before admission and spread to his abdomen.

A 32-year-old man who had HIV disease complained of headache, fever, and weakness on his right side. His history included intravenous drug use, Pneumocystis carinii pneumonia, and mucocutaneous candidiasis.

The wife of an 82-year-old man with Alzheimer's disease was concerned about her husband's poor posture. According to the woman, the patient had never sustained a back injury and had always maintained a sedentary lifestyle. He never smoked cigarettes and did not use alcohol. His history included multiple transient ischemic attacks (TIAs).

A 60-year-old comatose man was brought to the emergency department (ED). He had a history of diabetes, hypertension, and alcohol abuse. Relatives reported that the patient was noncompliant with his antihypertensive medication regimen.

Dull, constant, bifrontal headaches were the chief complaint of a 28-year-old woman who was referred for her first ophthalmologic examination. She had no specific ocular symptoms, but her primary care physician wanted to rule out an ophthalmologic cause for the headaches.

A week after the onset of headache, fever, chills, nausea, weakness, and malaise, a 23-year-old man presented to the emergency department of a hospital on Long Island in New York. He reported that analgesics had not eased his symptoms. The patient's only past hospitalization was a splenectomy secondary to an auto accident at age 16.

The initial complaint of a 79-year-old woman was of mild headache, neck pain, and sore throat. She had a history of hypertension, diabetes mellitus, and heavy cigarette smoking. Examination by an otolaryngologist, which included laryngoscopy, revealed no abnormalities. Three weeks later, the patient's throat and neck pain became more severe. She had no arthralgias, visual loss, fever, or worsening head pain.

A 51-year-old woman with severe migraines sought evaluation of a dozen round black macules on her hands, forearms, and legs. A few of the lesions had first appeared 1 year earlier; the remainder had erupted since then.

This 6-year-old boy was brought to his physician for evaluation of a rash. The child had been running a fever and, for the past 48 hours, had been complaining of a sore throat, headache, and abdominal pain.

A 40-year-old woman with a history of amenorrhea complained of recent headaches and galactorrhea for the last 6 months. A neurologic work-up revealed bitemporal hemianopia, and a radiograph of the skull suggested an enlarged sella turcica. A large pituitary adenoma disclosed by an MRI and a serum prolactin level of 360 µg/L led to a diagnosis of prolactinoma.

A comatose 29-year-old woman was brought to the emergency department. Her family reported that she had been well until 4 days earlier, when headache and fever developed. She went to another hospital at that time and was told she had an abscessed tooth. She was given erythromycin, and the tooth was extracted the following day. The patient's headache and fever worsened; a sore throat also developed, and a rash appeared on her trunk, arms, and legs. The family denied any HIV risk factors, unusual medical history, recent travel, and exposure to persons with infectious diseases.

A 57-year-old man was brought to the emergency department with severe bifrontal headache, which he had had for 3 weeks. Family members reported that the patient exhibited episodes of confusion and loss of recent memory since the onset of the headache.

While playing outside, a 23-month-old girl became sleepy and difficult to arouse. The mother brought her daughter to the emergency department (ED); posturing and a dilated and fixed right pupil were noted. The child was hospitalized.

Headache and vomiting suddenly developed in a 41-year-old woman who was 16 weeks pregnant. The next day, she suffered an episode of tonic-clonic seizures associated with a 15-minute loss of consciousness.

After suffering with a severe, disabling headache for 2 weeks, a 20-year-old soldier sought medical treatment. He had no significant medical history other than his 6-year history of smoking.

Increasingly frequent headaches and blurred vision had affected a 74-year-old woman for several months. Double vision, which initially occurred only when the patient looked to the right, had started to affect vision when she looked straight ahead. Her eye movements when looking to the left were normal; the right eye, however, did not go beyond midline when looking to the right. Upward and downward gaze were not affected.

A 66-year-old man presented with numerous cutaneous tumors. He had dementia and thus was unable to provide an accurate history.

A 57-year-old man complained of a severe headache of sudden onset while he was lifting heavy boxes. Within minutes, he collapsed and became unconscious. On arrival at the emergency department, the patient was deeply comatose. His pupils were 7 mm, fixed, and unreactive to light; brainstem reflexes were absent, and he was unresponsive to noxious stimulation. His blood pressure was 210/120 mm Hg; he had no known history of hypertension.

While doing yard work, a man experienced acute, severe, burning pain on relatively brief contact with the caterpillar Megalopyge opercularis. The lesion shown in the photograph developed subsequently. Each red papule represents the site of direct cutaneous envenomation by the insect's poisonous body hairs. The caterpillar can vary in color from white to dark brown, depending on the surroundings and time of year. The fuzzy hairs resemble a cat’s fur; hence the nickname “puss.”

A 75-year-old woman with a bioprosthetic aortic valve, who had undergone surgical repair of an aortic root aneurysm 9 months earlier was hospitalized with fever, headache, and altered mental status of 1-day's duration.

A 37-year-old man presented with fever, chills, myalgia, headache, and left-sided pleurisy of 2 weeks' duration. He also complained of weight loss and loss of appetite. The patient had recently returned from a family visit to Missouri.

32-year-old man presents with a 4-day history of fever (temperature as high as 38.8 C to 39.4 C with severe rigors, chills, and profuse night sweats; generalized myalgias, including dull, aching headache; and dry cough.

A 54-year-old woman with a history of hypertension presented with a worsening headache and a left hemisensory defect. A CT scan of her head without contrast showed a right parietal hemorrhage with spreading edema; the masslike effect caused shifting of the midline to the contralateral side. The patient gradually became comatose and required intubation for airway protection. Intravenous corticosteroids were administered to decrease the effect of the lobar hemorrhage. Fever developed 3 days after admission.

ABSTRACT: The management of chronic daily headache is difficult and complex. Those affected have a sensitive nervous system, and their predisposition for a low tolerance to sensory stimuli appears to be inherited. Under appropriate conditions, the equilibrium or balance between bombardment from painful stimuli and the regulatory systems that inhibit those stimuli is disrupted, allowing painful stimuli to become manifest at a greater intensity than in the nonmigraineur. Successful management depends on close adherence to nonpharmacologic approaches and pharmacologic regimens that desensitize the system and restore equilibrium. Comorbid conditions must be identified and treated as well.

A 71-year-old woman presents to the emergency department accompanied by her daughter. The patient woke up in the morning "feeling fine" and then complained of a headache. She became progressively less oriented over the next 45 minutes.

A 68-year-old man presents to the emergency department with diplopia and headache of acute onset accompanied by nausea and vomiting.

A 47-year-old man presented to theemergency department with adrooping right eye. He also complainedof a constant right-sidedheadache of 1 week’s duration; thepain involved the temporal region.Another physician had diagnosednew-onset migraine and prescribedsumatriptan, which failed to alleviatethe pain. The patient had no weakness,vomiting, or double vision.Both his father and his son hadMarfan syndrome.

A 65-year-old woman presented withdouble vision of 2 days’ duration.The diplopia mainly occurred whenshe looked toward her right. She deniednausea, vomiting, vision loss,headache, change in mental status,facial pain, weakness in the extremities,and sinus infection. She had nohistory of head trauma or systemicmalignancy.

The patient is a 47-year-old man who began to experiencefrequent headaches about 6 years before hepresented to a neurology clinic. The headaches rapidly progressedto become daily and almost constant. He describeda sensation of dull pressure in both temples that was presenton or within a few hours of awakening and that persistedfor the remainder of the day. He experienced a moreintense, disabling, throbbing pain in the same locationonce or twice a week, with photophobia and nausea, thatmight last 2 to 3 days. The patient took 2 to 6 over-thecounter(OTC) analgesic tablets each day-usually200 mg of ibuprofen. These would dull but not terminatethe pain.

ABSTRACT: When you approach a patient with a neurologic complaint, look for abnormal postures and bodily asymmetries. Careful history taking puts the patient's complaint in context and gives direction to the clinical investigation. Remember that a change in the character of an existing condition requires assessment as a new complaint. The mental status evaluation, at a minimum, considers the patient's level of alertness and orientation, including speech and comprehension. Distinguish among delirium, dementia, and psychosis, and avoid making a psychiatric diagnosis until organic causes have been excluded. Cranial nerves II to VIII are the most pertinent to the neurologic screening examination. The evaluation of cranial nerves II, III, IV, and VI is particularly important in patients with headache or visual disturbances and suspected intracranial lesions.
