Hypertension

For 2 days, a 68-year-old woman had watery, yellowish diarrhea with mucus and left lower quadrant pain. Her medical history included hypertension, diabetes mellitus, and congestive heart failure (CHF); she had left the hospital 5 days earlier following treatment of an exacerbation of CHF with intravenous furosemide and sodium and fluid restriction. The patient was taking furosemide, lisinopril, and glipizide; she denied any recent antibiotic therapy.

As many as half of patients who are evaluated for abdominal pain do not receive a precise diagnosis. And for about half of those who are given a diagnosis, the diagnosis is wrong. In this article, I will use actual cases (not "textbook" examples) to illustrate an approach to abdominal pain that begins with a careful differential diagnosis. I also offer some general guidelines for evaluating patients.

An 81-year-old man is seen for follow-up of leukocytosis detected during a recent hospitalization for community-acquired pneumonia. The leukocytosis had not resolved by the time he was discharged.

A systematic approach to the patient with resistant hypertension is both cost-effective and rewarding because the evaluation will probably reveal the cause. Initial considerations include lack of adherence, inappropriate treatment, drug-drug interactions, volume overload, and white-coat hypertension.

Each year, about 27 million Americans undergo anesthesia followed by surgery. Roughly 50,000 of these patients have a stress-induced myocardial infarction during the perioperative period.

The metabolic syndrome represents a clustering of conditions and/or risk factors that lead to an increased incidence of type 2 diabetes mellitus and cardiovascular disease. These conditions include abdominal obesity, dyslipidemia, hypertension, insulin resistance, and a proinflammatory state.

In their "What's The 'Take Home'?" case of a pregnant woman with hypertension, Drs Lawrence Kaplan and Ronald Rubin inquire into the most likely cause of the patient's elevated blood pressure. However, this information is not sufficient to make a definitive diagnosis.

An 83-year-old man with a history of hypertension and coronary artery disease presented with a 4-day history of mental status changes, slurred speech, and difficulty ambulating. He reported a lack of appetite and weakness of several days.

A serum alkaline phosphatase (ALP) level three times higher than normal, found on routine laboratory examination, prompted further evaluation of a 57-year-old man. At admission, his temperature was 36.8°C (98.2°F), blood pressure was 120/85 mm Hg, pulse rate was 90 beats per minute, and respiration rate was 19 breaths per minute. The physical examination was unrevealing, and the patient's personal and family medical histories were unremarkable.

A 62-year-old African American woman was brought to the emergency department (ED) after the sudden onset of slurred speech and weakness in her left arm and leg. Her medical history included hypertension, insulin-dependent diabetes, and congestive heart failure.

Frequent urinary tract infections and unexplained hypertension (160/100 mm Hg) occurred in a 38-year-old man with no significant medical history. The heart and chest were normal; a right lower quadrant mass was detected in the abdomen. Red blood cells were found in the urine. An abdominal CT scan demonstrated that the left kidney was fused to the lower pole of the right kidney with the left pelvicaliceal system to the left of the midline; these findings are consistent with crossed fused renal ectopia. Cystographic and cystoscopic examinations were normal.

A 35-year-old man, a smoker, had right pleuritic pain, productive cough, and fever for 3 days. His pulse rate was 107 beats per minute; respiratory rate, 14 breaths per minute; blood pressure, 136/80 mm Hg; and temperature, 37.7°C (99.9°F). There were signs of right upper lobe consolidation. Laboratory studies showed hyponatremia. Chest films showed a homogeneous density in the right upper lobe.

A 41-year-old man complaining of left-sided chest pain for 2 hours was examined in the emergency department (ED). On arrival, his blood pressure was 160/100 mm Hg; heart rate, 90 beats per minute; respiratory rate, 18 breaths per minute; oxygen saturation, 99%; and temperature, 37.2°C (99°F).

Police brought a delirious, combative 24-year-old man to the emergency department. The patient was unable to provide any history on arrival, but his scarred, blistering lips and his vital signs (blood pressure, 166/102 mm Hg; heart rate, 97 beats per minute; respiratory rate, 24 breaths per minute; and temperature, 38.2°C, or 100.9°F) led to a possible diagnosis of cocaine-induced delirium.

An 80-year-old woman presented with recurrent abdominal pain for 1 month, constipation, and vomiting. She had no diarrhea, rectal bleeding, or weight loss.

A 49-year-old woman with a history of alcoholic cirrhosis, esophageal varices, coronary artery disease, diabetes mellitus, and hypertension presented to the emergency department with a 2-day history of fever, chills, nausea, and back and abdominal pain.

Presenting symptoms of this 42-year-old man were left pleuritic pain and severe dyspnea while climbing stairs. He had a 2-year history of exertional dyspnea but had not sought medical advice. The patient's pulse was 123 beats per minute; respiratory rate, 45 breaths per minute; blood pressure, 80/45 mm Hg; and temperature, 37.3°C (99.1°F). Chest examination revealed hyperresonance with absence of breath sounds over the left hemithorax and wheezing over the right lung.

Levofloxacin, 500 mg/d, had been prescribed for a 74-year-old woman who had a urinary tract infection. The patient had type 2 diabetes and hypertension. She was allergic to sulfa drugs.

Her pulse rate was 96 beats per minute; blood pressure, 146/68 mm Hg; and respiration rate, 22 breaths per minute. She also had increased jugular venous distention; cardiovascular and chest examination findings were normal. Edema of both arms and dilated blood vessels on the anterior chest wall were noted.

A 72-year-old woman who had fallen and injured the left side of her chest came to the emergency department complaining of pain in that area. She was physically stable and not short of breath. A soft systolic murmur was heard over the left precordium; the lungs were clear. A posteroanterior chest film showed no rib fracture but it did show an enlarged heart and a large, calcified ventricular aneurysm.

A 97-year-old woman with a history of hypertension and a paraesophageal hiatal hernia presented with abdominal distention and shortness of breath. Three days earlier, she had fallen and sustained a hairline pelvic fracture; she was evaluated in the emergency department and given narcotics for the pain. Subsequently, the patient's abdomen became increasingly distended, and she had no bowel movement for 3 days.

Both of her legs had been amputated above the knee secondary to complications of type 2 diabetes mellitus.
