Neck and back conditions have significant effects on employee health and productivity. More than $7 billion in lost revenue in the United States annually can be attributed to workplace back pain among employees ages 40 to 65 years. According to the Bureau of Labor Statistics, in 2012 back pain was the most prevalent musculoskeletal condition resulting in workplace absenteeism. The incidence of these conditions is higher among individuals in certain professions, such as bus drivers, police officers, and correctional officers...

Lumbar spinal stenosis (LSS) is a frequent cause of chronic low back and lower extremity pain in older patients. Symptomatic LSS typically is described as neurogenic claudication consisting of pain, weakness, numbness, and/or fatigue arising in the back and radiating into the buttock, thigh, or lower leg. The diagnosis is complicated by lack of reliable clinical or x-ray criteria. North American Spine Society guidelines recommend magnetic resonance imaging study without contrast to confirm anatomic narrowing of the spinal canal or nerve root impingement...

Mechanical low back pain (LBP) is an injury or derangement of an anatomic structure in the low back. When evaluating patients with LBP, clinicians should maintain clinical suspicion for vertebral fracture, cancer, and cauda equina syndrome. Management includes patient education focused on exercise, massage, and behavioral approaches such as cognitive behavioral therapy. Acupuncture can be an effective alternative and specific herbal supplements may provide short-term pain relief. The prognosis for patients with mechanical LBP is good...

There are a variety of causes of neck pain, including trauma and degenerative changes. The history of onset helps to direct evaluation, including the need for imaging or ancillary testing. Patterns of pain, weakness, and other specific physical examination findings also aid in diagnosis. Management of most soft tissue injuries involves early mobilization, whereas fractures are managed based on patterns of instability. Acute spinal cord injury requires emergent care, to include possible decompressive surgery...

Deepa Burman
Shift work sleep disorder is a common problem in industrialized countries because of the need for occupations and services to continue to function 24 hours/day. Approximately 20% of employed adults in the United States are engaged in shift work. Shift work sleep disorder is diagnosed if there is a report of insomnia or excessive sleepiness for at least 3 months associated with a recurring work schedule that overlaps the usual time for sleep. Shift work is associated with an increased occurrence of metabolic disorders, such as insulin resistance, diabetes, dyslipidemia, and metabolic syndrome, and it has been implicated in weight gain and cognitive impairment...

REVIEW
Deepa Burman
Restless legs syndrome (RLS) is a common disorder that often is underdiagnosed and undertreated. Patients with RLS describe an urge to move their legs, especially in the evenings and during periods of inactivity. The prevalence of clinically significant RLS is approximately 2% to 3% in adults in Europe and North America. RLS can be an independent disorder or may occur in conjunction with other conditions (eg, iron deficiency, pregnancy, chronic renal failure). Diagnosis is based on clinical history. Routine polysomnography typically is not recommended unless there is suspicion of other sleep disorders (eg, obstructive sleep apnea)...

REVIEW
Deepa Burman
Insomnia is the most common type of sleep disorder in the family medicine population. It is defined as a persistent difficulty initiating or maintaining sleep, or a report of nonrestorative sleep, accompanied by related daytime impairment. Insomnia is a significant public health problem because of its high prevalence and management challenges. There is increasing evidence of a strong association between insomnia and various medical and psychiatric comorbidities. Diagnosis of insomnia and treatment planning rely on a thorough sleep history to address contributing and precipitating factors as well as maladaptive behaviors resulting in poor sleep...

Sleep-related breathing disorders or sleep-disordered breathing are characterized by abnormal respiration during sleep. They are grouped into obstructive sleep apnea (OSA), central sleep apnea, sleep-related hypoventilation, and sleep-related hypoxemia disorder. OSA is a common disorder encountered in the family medicine setting that is increasingly being recognized because of the obesity epidemic and greater public and physician awareness. OSA is characterized by recurrent episodes of partial or complete closure of the upper airway resulting in disturbed breathing during sleep...

REVIEW
Lisa Harris
Oral electrolyte solutions are used widely for rehydration in diarrheal illness and to maintain hydration during vigorous exercise. In diarrheal illness, an oral rehydration solution (ORS) typically is preferred over intravenous fluids except for patients with severe dehydration. The preferred ORS is one similar to the glucose-containing reduced osmolarity World Health Organization ORS. There also are polymer-based solutions that use rice or wheat as the source of carbohydrates but these are not widely recommended...

REVIEW
Craig Barstow
A normal serum calcium level is 8 to 10 mg/dL. The diagnosis of hypercalcemia (ie, levels 10.5 mg/dL or greater) should be confirmed with an albumin-adjusted or ionized calcium level. The two most common causes of hypercalcemia are hyperparathyroidism and malignancy. Drugs, notably lithium and thiazide diuretics, also can cause hypercalcemia. Patients with severe or symptomatic hypercalcemia should be treated initially with hydration to decrease calcium levels. The evaluation should include a parathyroid hormone (PTH) level...

Taiwona L Elliott
Hypokalemia (ie, potassium levels less than 3.5 mEq/L) occurs in fewer than 1% of healthy individuals, but is present in up to 20% of hospitalized patients, 40% of patients taking diuretics, and 17% of patients with cardiovascular conditions. Hypokalemia often is asymptomatic; symptoms are more common in older adults. Common symptoms are cardiac arrhythmias and muscle weakness or pain. Management consists of intravenous potassium replacement during cardiac monitoring for patients with marked symptoms, echocardiogram (ECG) abnormalities, or severe hypokalemia (ie, level less than 3...

REVIEW
Michael M Braun, Megan Mahowald
Sodium disorders (ie, hyponatremia, hypernatremia) are common electrolyte disturbances in clinical medicine and are associated with increased rates of morbidity and mortality. Etiologies of hyponatremia are classified into four categories. The first is pseudohyponatremia, in which the sodium level is low due to hyperproteinemia, hyperlipidemia, or hyperglycemia. The other three categories are based on overall patient fluid status and include hypovolemic (commonly due to fluid loss), hypervolemic (commonly due to fluid retention from heart failure, cirrhosis, or renal failure), and euvolemic (most often because of syndrome of inappropriate secretion of antidiuretic hormone)...

Asymptomatic patients with gallstones typically do not require treatment. Surgical intervention is indicated in most symptomatic patients with gallstones. For patients with uncomplicated cholecystitis, laparoscopic cholecystectomy performed within 24 hours of admission is associated with significantly decreased morbidity, hospital length of stay, and cost. Most gallbladder polyps are found incidentally during ultrasonography. Patients with gallbladder polyps are at increased risk of malignant transformation if they are older than 50 years; the gallbladder wall is thickened; or the polyp is adenomatous, solitary, larger than 10 mm, sessile in appearance, or has a rapid increase in size...

Ku-Lang Chang, David S Estores
The most common etiologies of acute pancreatitis are gallstones (particularly 5 mm or smaller) and alcohol consumption. The serum amylase level may be normal in up to one-fifth of patients with acute pancreatitis; therefore, this level by itself is not a reliable diagnostic factor. The serum lipase level has a higher positive predictive value and specificity compared with the amylase level. Acute biliary pancreatitis with evidence of cholangitis represents an emergency indication for endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy within 24 hours of presentation...

Functional dyspepsia can be categorized into two syndromes: postprandial distress syndrome and epigastric pain syndrome. Helicobacter pyloriinfection is one of the most common chronic infections worldwide. Acute H pylori infection causes dyspepsia, and chronic infection can cause peptic ulcer disease. H pylori also is one of the causative agents in gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The incidence of H pylori infection varies among different ethnic populations and geographic locations...

Eosinophilic esophagitis (EE) is an allergic disorder of the esophagus. This diagnosis requires the presence of specific symptoms and a significantly elevated number of eosinophils in the esophageal lining as determined by endoscopic biopsies. Symptoms tend to be nonspecific among patients younger than 15 years. Among adults, dysphagia is the most common symptom. Comanagement with a gastroenterology subspecialist is essential, particularly for EE patients with a stricture. EE is commonly misdiagnosed as gastroesophageal reflux disease (GERD)...
