Chronic Constipation in Adults.

Chronic constipation has significant quality-of-life implications. Modifiable risk factors include insufficient physical activity, depression, decreased caloric intake, and aggravating medication use. Chronic constipation is classified as primary (normal transit, slow transit, defecatory disorders, or a combination) or secondary (due to medications, chronic diseases, or anatomic abnormalities). Evaluation begins with a detailed history, medication reconciliation, and physical examination. Routine use of laboratory studies or imaging, including colonoscopy, is not recommended in the absence of alarm symptoms. Patients with alarm symptoms or who are overdue for colorectal cancer screening should be referred for colonoscopy. First-line treatment for primary constipation includes ensuring adequate fluid intake, dietary fiber supplementation, and osmotic laxatives. Second-line therapy includes a brief trial of stimulant laxatives followed by intestinal secretagogues. If the initial treatment approach is ineffective, patients should be referred to gastroenterology for more specialized testing, such as anorectal manometry and a balloon expulsion test. Patients with refractory constipation may be considered for surgery. Those in whom pelvic floor dysfunction is identified early should be referred for pelvic floor therapy with biofeedback while first-line medications, such as bulk or osmotic laxatives, are initiated.

Obstetric Lacerations: Prevention and Repair.

Obstetric lacerations are a common complication of vaginal delivery. Lacerations can lead to chronic pain and urinary and fecal incontinence. Perineal lacerations are defined by the depth of musculature involved, with fourth-degree lacerations disrupting the anal sphincter and the underlying rectal mucosa and first-degree lacerations having no perineal muscle involvement. Late third-trimester perineal massage can reduce lacerations in primiparous women; perineal support and massage and warm compresses during the second stage of labor can reduce anal sphincter injury. Conservative care of minor hemostatic first- and second-degree lacerations without anatomic distortion reduces pain, analgesia use, and dyspareunia. Minor hemostatic lesions with anatomic disruption can be repaired with surgical glue. Second-degree lacerations are best repaired with a single continuous suture. Lacerations involving the anal sphincter complex require additional expertise, exposure, and lighting; transfer to an operating room should be considered. Limited evidence suggests similar results from overlapping and end-to-end external sphincter repairs. Postdelivery care should focus on controlling pain, preventing constipation, and monitoring for urinary retention. Acetaminophen and nonsteroidal anti-inflammatory drugs should be administered as needed. Opiates should be avoided to decrease risk of constipation; need for opiates suggests infection or problem with the repair. Osmotic laxative use leads to earlier bowel movements and less pain during the first bowel movement. Simulation models are recommended for surgical technique instruction and maintenance, especially for third- and fourth-degree repairs.

Febrile Seizures: Risks, Evaluation, and Prognosis.

A febrile seizure is a seizure occurring in a child six months to five years of age that is accompanied by a fever (100.4°F or greater) without central nervous system infection. Febrile seizures are classified as simple or complex. A complex seizure lasts 15 minutes or more, is associated with focal neurologic findings, or recurs within 24 hours. The cause of febrile seizures is likely multifactorial. Viral illnesses, certain vaccinations, and genetic predisposition are common risk factors that may affect a vulnerable, developing nervous system under the stress of a fever. Children who have a simple febrile seizure and are well-appearing do not require routine diagnostic testing (laboratory tests, neuroimaging, or electroencephalography), except as indicated to discern the cause of the fever. For children with complex seizures, the neurologic examination should guide further evaluation. For seizures lasting more than five minutes, a benzodiazepine should be administered. Febrile seizures are not associated with increased long-term mortality or negative effects on future academic progress, intellect, or behavior. Children with febrile seizures are more likely to have recurrent febrile seizures. However, given the benign nature of febrile seizures, the routine use of antiepileptics is not indicated because of adverse effects of these medications. The use of antipyretics does not decrease the risk of febrile seizures, although rectal acetaminophen reduced the risk of short-term recurrence following a febrile seizure. Parents should be educated on the excellent prognosis of children with febrile seizures and provided with practical guidance on home management of seizures.

Applying the chronic care model to prenatal care: Patient activation, productive interactions, and prenatal outcomes.

OBJECTIVE: To demonstrate how the chronic care model can be applied in prenatal care. METHODS: This study was conducted through analysis of data generated in the women's health and family medicine departments of one community hospital and two medical centers across three states (Georgia, Nevada, and Virginia). 159 low-risk obstetric patients were monitored throughout their pregnancy for patient activation and biometric measures including: blood pressure at each appointment, baby's gestational age at birth, and mode of delivery. Patient activation was assessed with the validated, licensed patient activation measure. RESULTS: Patient activation was strongly associated with the Prenatal Interpersonal Processes of Care metric (F (2, 155) = 3.41, p < .05). Also, increased age, decreased Prenatal Interpersonal Processes of Care, fewer pregnancies, and increased diastolic blood pressure were associated with an increased likelihood of cesarean delivery and the model correctly predicted 81% of cases. CONCLUSION: Women who identified as feeling more activated reported more positive pregnancy experiences, and women who reported more positive pregnancy experiences were more likely to experience a vaginal delivery. PRACTICE IMPLICATIONS: Activated patients, more positive prenatal experience, and improved delivery outcomes can be achieved through applying the chronic care model.
