Sleep Disorders

DETROIT -- Patients with mild symptoms of sleep apnea are less likely to follow treatment plans using a positive airway pressure machine (PAP), found researchers here.

WATERTOWN, Mass. -- Instead of popping pills, men with erectile dysfunction may be able to improve their performance through weight loss and getting in shape.

ROCKVILLE, Md. -- The demand for obesity surgery has swelled by nearly 2,000% from 1998 to 2004, according to the federal Agency for Healthcare Research and Quality.

PITTSBURGH -- Poor sleep is a frequent companion of depression in children, according to researchers here.

A study conducted in France provides further evidence of how allergic rhinitis adversely affects quality of life. Léger and associates found that allergic rhinitis impairs all dimensions of sleep quality.

ABSTRACT: Irritable bowel syndrome (IBS) is characterized by abdominal pain or discomfort, bloating, and constipation or diarrhea; the pain is typically relieved by defecation. The diagnosis is not one of exclusion; it can be made based on the answers to a few key questions and the absence of "alarm" symptoms. Fiber therapy, the elimination of particular foods, and regulation of bowel function can help relieve symptoms. Tegaserod or polyethylene glycol can be used to treat IBS with constipation. Loperamide and alosetron are of benefit in IBS with diarrhea (although the latter carries a small risk of ischemic colitis). Low-dose tricyclic antidepressants may be used to treat the abdominal pain associated with IBS. Probiotic therapy or rifaximin may help reduce bloating. Psychological therapies seem to improve well-being in patients with IBS.

A 5-year-old boy was referredfor evaluation of afemur fracture.

Q:How can I accurately determine when a patient’s hypertension isresistant to treatment-and what is the best approach to theevaluation?

abstract: The keystone of influenza prevention is still vaccination. The 2 available types of influenza vaccine--the inactivated vaccine, which is administered intramuscularly, and the attenuated vaccine, which is delivered via nasal spray--have efficacy rates of 70% to 80%. Unfortunately, only about 65% of persons who should receive the influenza vaccine are, in fact, vaccinated. The neuraminidase inhibitors oseltamivir and zanamivir are 70% to 90% effective in preventing influenza. These antivirals also are effective in reducing the severity of influenza symptoms and the duration of illness when administered within 48 hours of the onset of clinical disease. Some patients have difficulty in self-administering zanamivir because the inhalation process is fairly complicated. Because of the resistance pattern observed in 2005, amantadine and rimantadine are not currently recommended for prophylaxis or therapy. (J Respir Dis. 2007;28(1):21-29)

A 62-year-old woman was found on thefloor of her bathroom at home with herwheelchair partially on top of her.She was unresponsive except to painfulstimulus.

In his Hypertension Q&A, “When Snoring Has More OminousConsequences Than a Sleepless Spouse” (CONSULTANT,October 2003, page 1410), Dr Donald Vidt suggestsseveral questions that a physician can ask patients to screenfor obstructive sleep apnea (OSA).

A 12-year-old boy complains of severe weekly headaches that last 2 to 3 hours. The pain involves both sides ofthe head and the frontal and occipital areas. Occasionally during a headache, the patient complains of some abdominaldiscomfort and pain. He becomes passive and irritable during the headache; he does not want to be aroundpeople, play, or even watch TV. The patient’s parents note that a few hours before a headache, he becomes somewhatrestless and agitated. The headaches started about 1 year earlier, and the headache pattern (frequency, duration,location of pain, and associated symptoms) has not changed since that time. The patient’s mother and maternalgrandmother suffer from migraine.

ABSTRACT: The key factor in reducing morbidityand mortality in patients with chronicobstructive pulmonary disease (COPD)continues to be smoking cessation. Newerformulations of nicotine replacementtherapy-a nasal spray and an inhaler-provide rapid delivery of nicotine and maybe appropriate for highly dependent smokers.Bupropion has been shown to improvesmoking cessation rates, either when usedalone or with a nicotine patch. Both theinfluenza and pneumococcal vaccines arerecommended to reduce the morbidity andmortality associated with respiratory infectionsin patients with COPD.

A 72-year-old farmer is brought by his daughter for a comprehensivegeriatric assessment. His previous history is unremarkable. The patientreports that he has had vivid visual hallucinations, which he calls "visitors." He becomes frightenedand hostile when these incidents occur; on several occasions, he has exhibited violent behavioras persons around him tried to calm him. Although the patient was able to recall each episode indetail, he felt as if he had watched it from a distance and had not been an active participant.

Primary care doctor: Because of the patient’s age and theabsence of a headache history, I first considered such secondarycauses as tumor and temporal arteritis. However,MRI of the brain and erythrocyte sedimentation rate werenormal. I now suspect a sleep-related headache becausethe attacks occur only at night and awaken the patientfrom a sound sleep. How can I determine which type ofsleep-related headache is involved?

A 75-year-old man with a 120-pack-year smoking history has dyspnea on exertion(eg, when he walks more than 3 blocks or climbs 1 flight of stairs) butnot when he is at rest or asleep. His symptoms have progressively worsenedover the past 3 to 4 years and have been accompanied by a 20-lb weight loss.

A 32-year-old woman is admitted to the hospital because of nausea, vomiting,and mild jaundice. For 4 days, her health has steadily deteriorated: hepatictransaminase and bilirubin levels are elevated, prothrombin time is prolongedand, most recently, obtundation and changes in mentation have developed.Serologic studies for infection with hepatitis A, B, and C viruses are negative,as are tests for Epstein-Barr virus mononucleosis.

An 87-year-old man had recently been hospitalized for5 days for treatment of hypernatremia and dehydration.His condition improved following hydration and cautiouscorrection of the hypernatremia, and he was discharged.However, within 48 hours the patient's caregiver notedthat he was obtunded and less responsive; she broughthim to the emergency department.

An 84-year-old man with back and abdominal pain ofrecent onset arrives at the emergency department(ED) of a small community hospital at 5 AM. Sudden,severe back pain awakened him from sleep 2 hours earlier.The patient has had back pain for 12 hours and intermittentcolicky pain in the suprapubic region for the past2 hours.

Q:How frequently does hypertension occur in association withobstructive sleep apnea (OSA), and how is OSA best treated?

Q:Recent research has defined mild cognitiveimpairment as a transitional state between thecognitive changes of normal aging and Alzheimerdisease (AD) and other dementing illnesses. Whatcriteria are used to differentiate mild cognitiveimpairment from more innocuous syndromes, such asbenign senescent forgetfulness? Are patients with mildcognitive impairment considered to have incipientclinical AD?

For 2 days, a 45-year-old woman has had a painful rash on her left upper chest,upper back, neck, shoulder, and upper arm; she has also had pain around herleft ear. She describes the pain as burning, needlelike, and so severe that it hasprevented sleep; it is unrelieved by topical emollients. The rash was precededby 24 hours of a similar burning pain in the same area. No neurologic deficitsare associated with the rash. She has no history of rashes; no pain or rashesoccur elsewhere on her body.

A 41-year-old woman presents as a new patient, with complaintsof chest pain and palpitations that occur intermittentlyand are not associated with activity, meals, or position.She says these symptoms have been present forsome time, and she expresses frustration that her previousphysician was unable to find their cause or to amelioratethem.

The patient is a 4-year-old boy who hasbeen coughing persistently for the past 2months. The mother reports that aboutthe time the coughing began, the childhad a “cold” with nasal congestion andfever. These symptoms resolved, but acough ensued. The mother tried usingover-the-counter medications, includingcough suppressants, but the cough hasnot abated. It occurs during the day andat night. It is disrupting the child’s sleep,and the teachers at his day-care centerare concerned that he may be infectingother children.

A 40-year-old woman reports increasingly frequent and severe headaches during the past few months. She has had boutsof severe headaches since college, and episodic migraine was diagnosed a decade ago. She uses over-the-counter products(ibuprofen, ketoprofen, or aspirin) at the onset of an attack; if these fail to relieve symptoms, she takes hydrocodone/acetaminophen. During her worst attacks, she is typically forced to halt her activities, is unable to eat or drink, and mayvomit. For unresponsive or persistent (more than 24-hour) attacks, her husband drives her to the urgent care centerfor intravenous hydration, intramuscular promethazine, and additional doses of hydrocodone/acetaminophen. Accordingto the patient, a visit to the urgent care center “completely ruins our day.”

In recent years, 2 large randomized,controlled studies have documentedthe efficacy of the anticonvulsantgabapentin in the management ofpainful diabetic neuropathy (PDN)1and post-herpetic neuralgia (PHN).2Although vastly different in origin,these 2 neuropathies have exhibitedsome similarities in their response totherapeutic agents of various classes.The discovery that yet another typeof pharmaceutical is useful in treatingpain from either PDN or PHN hasraised questions about the similaritiesand differences in the managementof these 2 painful neuropathicsyndromes.

Q:Which patients with chronic respiratory disorders are good candidatesfor pulmonary rehabilitation? When is it a better option than surgery?

An 84-year-old woman presents with a 3-year history of slowly progressivememory impairment accompanied by functional decline. Thepatient lives alone but has been receiving an increasing amount of support from her 2 daughters,who accompany her to the appointment. The daughters first noticed that their mother was havingtrouble driving. About a year ago, she started forgetting family recipes. She also left food cookingon the stove unattended and burned several pans. Currently, the daughters are providing mealsand transportation, assisting with housework, and doing their mother’s laundry. They have becomeincreasingly alarmed because she takes her medications only sporadically, despite the factthat they fill her pillboxes and call her regularly with reminders. Their chief concern is whether itis safe for their mother to continue to live alone.

A 45-year-old man has a history of migraine that started shortly after puberty. The headaches became more frequent andsevere 3 years ago, when the patient was promoted from metal worker to shift boss.
