Diarrhea

Diarrhea

Frequent loose bowel movements (4 to 6/day) may occur in normal infants; they are of no concern unless anorexia, vomiting, weight loss, failure to gain weight, or passage of blood also occurs. Breastfed infants tend to have frequent bowel movements, especially if they are not receiving solid food. The significance of diarrhea in a child at any age differs if it is acute (< 2 wk) or chronic (> 2 wk).

Etiology

Acute diarrhea is most likely infectious, especially if onset is sudden or accompanied by vomiting, bloody stools, fever, anorexia, or listlessness. Diagnosis is clinical, and treatment is supportive until the condition resolves spontaneously.

Chronic diarrhea is usually more significant. Causes include gluten-induced enteropathy, cystic fibrosis, sugar malabsorption, and allergic gastroenteropathy. Inflammatory bowel disease and some infections (eg, with Giardia) can also cause chronic diarrhea.

With gluten-induced enteropathy (celiac sprue), the gluten fraction of wheat protein causes intestinal mucosal damage and malabsorption of dietary fats, resulting in malnutrition, anorexia, and bulky, foul-smelling stools. The change in stools starts when wheat and other gluten-containing foods are added.

With cystic fibrosis, pancreatic insufficiency results in trypsin and lipase deficits, causing high fecal losses of protein and fats with consequent malnutrition and growth retardation. The stool is voluminous and often foul-smelling. Children who have cystic fibrosis often have respiratory problems and growth failure.

With sugar malabsorption, intestinal mucosal enzymes, such as lactase, which splits lactose to galactose and glucose, may be congenitally absent or temporarily deficient secondary to GI infection. Improvement after eliminating lactose (or other carbohydrates) from the diet or after substituting a lactose-free formula strongly suggests the diagnosis.

With allergic gastroenteropathy, cow's milk protein may cause diarrhea, often with vomiting and blood in the stools, but intolerance to the carbohydrate fraction of the ingested food should be suspected also. Symptoms often abate promptly when soy formula is substituted for cow's milk and return if cow's milk is reintroduced. Some infants intolerant of cow's milk are also intolerant of soy, so a formula that has had the protein pre-digested and does not contain the offending disaccharide may be needed. Spontaneous improvement usually occurs toward the end of the 1st yr.

Treatment

Supportive care for acute diarrhea consists primarily of providing adequate oral (or rarely IV) rehydration. Antimotility agents (eg, loperamide: IMODIUM) are generally not recommended for infants and young children.

For chronic diarrhea, adequate nutrition must be maintained, particularly of fat-soluble vitamins. Specific treatments are indicated for certain causes (eg, gluten-free diet for those with celiac disease).



Sleeping

Sleeping

Sleep behaviors are culturally determined, and problems tend to be defined as behaviors that vary from accepted customs or norms. In cultures where children sleep separately from their parents in the same house, sleep problems are among the most common that parents and children face. Infants generally adapt to a day-night sleep schedule between 4 and 6 mo. Sleep problems beyond these ages take many forms, including difficulty falling asleep at night, frequent nighttime awakening, atypical daytime napping, and dependence on feeding or being held for sleep. These problems are related to parental expectations, the child's temperament and biologic rhythms, and child-parent interactions. Inborn biologic patterns are central to an infant's sleep patterns, whereas emotional factors and established habits become more important in the toddler and older child. In addition, sleep disturbances become common at 9 mo and again around 18 mo, when separation anxiety, increasing ability of the child to move independently and control his environment, long late-afternoon naps, overstimulating play before bedtime, and nightmares tend to become more common.

Treatment

The clinician's role in treatment is to present explanations and options to parents, who must implement changes to get the child on an acceptable sleep schedule. Approaches vary with age and circumstances. Infants are often comforted by swaddling, ambient noise, and movement. However, always rocking the infant to sleep does not allow the infant to learn how to fall asleep on his own, which is an important developmental task. As a substitute for rocking, the parent can sit quietly by the crib until the infant falls asleep, and the infant eventually learns to be comforted and to fall asleep without being held. All children awaken during the night, but children who have been taught to fall asleep by themselves will usually settle themselves back to sleep. When a child is unable to get back to sleep, parents can check on the child to reassure themselves of the child's safety and to reassure the child, but the child should then be allowed to settle himself back to sleep.

In older children, a period of "winding down" with quiet activities such as reading at bedtime facilitates sleep. A consistent bedtime is important, and a fixed ritual is helpful for young children. Asking a fully verbal child to recount the events of the day often eliminates nightmares and waking. Encouraging exercise in the daytime, avoiding scary television programs and movies, and refusing to allow bedtime to become an element of manipulation also help prevent sleep problems. Stressful events (eg, moving, illness) may cause acute sleep problems in older children; reassurance and encouragement are always ultimately effective. Allowing the child to sleep in the parents' bed in such instances almost always prolongs rather than resolves the problem.



Acute Respiratory Distress Syndrome

Acute Respiratory Distress Syndrome
  
Definition/Description
 
Acute respiratory distress syndrome (ARDS) is breathing failure that can occur in critically ill persons with underlying illnesses. When one develops ARDS, severe fluid buildup occurs in both lungs and prevents the lungs from transfering oxygen from air into the body and carbon dioxide out of the body into the air. Noncardiogenic pulmonary edema; increased-permeability pulmonary edema; stiff lung; shock lung; and acute lung injury are its alternative names.
 
Causes
  
ARDS can be caused by any major swelling (inflammation) or injury to the lung. Some common causes include:
 
◆ Aspiration)
 
◆ Pneumonia
 
◆ Septic shock
 
◆ Trauma

ARDS leads to a buildup of fluid in the alveoli, which prevents enough oxygen from passing into the bloodstream.
 
The fluid buildup also makes the lungs heavy and stiff, and decreases the lungs' ability to expand. The level of oxygen in the blood can stay dangerously low, even if the person receives oxygen from mechanical ventilator through endotracheal tube.
 
ARDS often occurs along with the failure of other organ systems, such as the liver or the kidneys. Cigarette smoking and heavy alcohol use may be risk factors.
 
Symptoms/Signs

Symptoms usually develop within 24 to 48 hours of the initial injury or illness. Often, people with ARDS are so sick they are unable to complain of symptoms. However, the major signs and symptoms are:
 
◆ Dyspnea, tachypnea
 
◆ Hypotention and organ failure

◆ Cyanosis
 
Examinations/Tests
 
Listening to the chest with a stethoscope (auscultation) reveals abnormal breath sounds, such as crackles that suggest fluid in the lungs. Often the blood pressure is low. Cyanosis (blue skin, lips, and nails caused by lack of oxygen to the tissues) is often seen.

Tests used to diagnose ARDS include:

◆ Arterial blood gas

◆ Bronchoscopy

◆ CBC and blood chemistries

◆ Chest x-ray

◆ Sputum cultures and analysis

◆ Tests for possible infections

Occasionally an echocardiogram or Swan-Ganz catheterization may need to be done to rule out congestive heart failure, which can look similar to ARDS on a chest x-ray.

Treatment

Typically persons with ARDS need to be in an intensive care unit (ICU). The goal of treatment is to provide breathing support and treat the underlying cause of ARDS. This may involve medications to treat infections, reduce inflammation, and remove fluid from the lungs.

A breathing machine is used to deliver high doses of oxygen and a continuous level of pressure called PEEP (positive end-expiratory pressure) to the damaged lungs. Patients often need to be deeply sedated with medications when using this equipment.

Many different kinds of medicines are used to treat ARDS patients. Some kinds of medicines often used include:

◆ Antibiotics to fight infection

◆ Pain relievers

◆ Drugs to relieve anxiety and keep the patient calm

◆ Drugs to raise blood pressure or stimulate the heart

◆ Muscle relaxers to prevent movement and reduce the body's demand for oxygen

Complications

Common complications in ARDS patients are infections with hospital-acquired bacteria and leaks of air out of the lungs into other body spaces. These include:

◆ Lung damage (such as pneumothorax) due to use of high settings on the breathing machine needed to treat the disease

◆ Multiple organ system failure

◆ Pulmonary fibrosis

◆ Ventilator-associated pneumonia

Prognosis

About a third of people with ARDS die from the disease. Survivors usually get back normal lung function, but many people have permanent, usually mild, lung damage.

Many people who survive ARDS have memory loss or other problems with thinking after they recover. This is due to brain damage that occurred when the lungs weren't working properly and the brain wasn't getting enough oxygen.
