Depression in Children and Adolescents - Article
ABSTRACT: Depression among children and adolescents is common but frequently unrecognized. It affects 2 percent of prepubertal children and 5 to 8 percent of adolescents. The clinical spectrum of the disease can range from simple sadness to a major depressive or bipolar disorder. Risk factors include a family history of depression and poor school performance. Evaluation should include a complete medical assessment to rule out underlying medical causes. A structured clinical interview and various rating scales such as the Pediatric Symptom Checklist are helpful in determining whether a child or adolescent is depressed. Evidence-based treatment guidelines from the literature are limited. Psychotherapy appears to be useful in most children and adolescents with mild to moderate depression. Tricyclic antidepressants and selective serotonin reuptake inhibitors are medical therapies that have been studied on a limited basis. The latter agents are better tolerated but not necessarily more efficacious. Because the risk of school failure and suicide is quite high in depressed children and adolescents, prompt referral or close collaboration with a mental health professional is often necessary.
Mirtazapine: A Newer Antidepressant - Article
ABSTRACT: Mirtazapine is a newer antidepressant that exhibits both noradrenergic and serotonergic activity. It is at least as effective as the older antidepressants for treating mild to severe depression. Sedation is the most common side effect. Although agranulocytosis is the most serious side effect, it is rare (approximately one in 1,000) and usually reversible when the medication is stopped. Mirtazapine is relatively safe in overdose. Many clinicians consider mirtazapine a second-line or even third-line antidepressant to be used when older antidepressants are not tolerated or are ineffective. Physicians who are concerned about the risks of elevated lipid levels and agranulocytosis may choose to reserve mirtazapine as a third-line choice. It is particularly useful in patients who experience sexual side effects from other antidepressants. Mirtazapine is also a good choice in depressed patients with significant anxiety or insomnia. Although mirtazapine has been used successfully in Europe for a number of years, its place in the care of patients with depression in the United States has not yet been established.
ABSTRACT: Herpes zoster (commonly referred to as "shingles") and postherpetic neuralgia result from reactivation of the varicella-zoster virus acquired during the primary varicella infection, or chickenpox. Whereas varicella is generally a disease of childhood, herpes zoster and post-herpetic neuralgia become more common with increasing age. Factors that decrease immune function, such as human immunodeficiency virus infection, chemotherapy, malignancies and chronic corticosteroid use, may also increase the risk of developing herpes zoster. Reactivation of latent varicella-zoster virus from dorsal root ganglia is responsible for the classic dermatomal rash and pain that occur with herpes zoster. Burning pain typically precedes the rash by several days and can persist for several months after the rash resolves. With postherpetic neuralgia, a complication of herpes zoster, pain may persist well after resolution of the rash and can be highly debilitating. Herpes zoster is usually treated with orally administered acyclovir. Other antiviral medications include famciclovir and valacyclovir. The antiviral medications are most effective when started within 72 hours after the onset of the rash. The addition of an orally administered corticosteroid can provide modest benefits in reducing the pain of herpes zoster and the incidence of postherpetic neuralgia. Ocular involvement in herpes zoster can lead to rare but serious complications and generally merits referral to an ophthalmologist. Patients with postherpetic neuralgia may require narcotics for adequate pain control. Tricyclic antidepressants or anticonvulsants, often given in low dosages, may help to control neuropathic pain. Capsaicin, lidocaine patches and nerve blocks can also be used in selected patients.
ABSTRACT: Interstitial cystitis is a chronic, severely debilitating disease of the urinary bladder. Excessive urgency and frequency of urination, suprapubic pain, dyspareunia, chronic pelvic pain and negative urine cultures are characteristic of interstitial cystitis. The course of the disease is usually marked by flare-ups and remissions. Other conditions that should be ruled out include bacterial cystitis, urethritis, neoplasia, vaginitis and vulvar vestibulitis. Interstitial cystitis is diagnosed by cystoscopy and hydrodistention of the bladder. Glomerulations or Hunner's ulcers found at cystoscopy are diagnostic. Oral treatments of interstitial cystitis include pentosan polysulfate, tricyclic antidepressants and antihistamines. Intravesicular therapies include hydrodistention, dimethyl sulfoxide and heparin, or a combination of agents. Referral to a support group should be offered to all patients with interstitial cystitis.
Evaluation and Treatment of Enuresis - Article
ABSTRACT: Enuresis is defined as repeated, spontaneous voiding of urine during sleep in a child five years or older. It affects 5 to 7 million children in the United States. Primary nocturnal enuresis is caused by a disparity between bladder capacity and nocturnal urine production and failure of the child to awaken in response to a full bladder. Less commonly, enuresis is secondary to a medical, psychological, or behavioral problem. A diagnosis usually can be made with a history focusing on enuresis and a physical examination followed by urinalysis. Imaging and urodynamic studies generally are not needed unless specifically indicated (e.g., to exclude suspected neurologic or urologic disease). Primary nocturnal enuresis almost always resolves spontaneously over time. Treatment should be delayed until the child is able and willing to adhere to the treatment program; medications are rarely indicated in children younger than seven years. If the condition is not distressing to the child, treatment is not needed. However, parents should be reassured about their child's physical and emotional health and counseled about eliminating guilt, shame, and punishment. Enuresis alarms are effective in children with primary nocturnal enuresis and should be considered for older, motivated children from cooperative families when behavioral measures are unsuccessful. Desmopressin is most effective in children with nocturnal polyuria and normal bladder capacity. Patients respond to desmopressin more quickly than to alarm systems. Combined treatment is effective for resistant cases.
Treatment-Resistant Depression - Article
ABSTRACT: Up to two thirds of patients with major unipolar depression will not respond to the first medication prescribed. Depression may be considered resistant to treatment when at least two trials with antidepressants from different pharmacologic classes (adequate in dose, duration, and compliance) fail to produce a significant clinical improvement. Evidence regarding the effectiveness of psychotherapy for treatment-resistant depression is limited. A recent high-quality trial found that patients who did not respond to citalopram and who received cognitive behavior therapy (with or without continued citalopram) had similar response and remission rates to those who received other medication regimens. Initial remission rates in that trial were 37 percent, and even after three additional trials of different drugs or cognitive behavior therapy, the cumulative remission rate was only 67 percent. In general, patients who require more treatment steps have higher relapse rates, and fewer than one half of patients achieve sustained remission. No treatment strategy appears to be better than another. Electroconvulsive therapy is effective as short-term therapy of treatment-resistant depression. There is no good-quality evidence that vagal nerve stimulation is an effective treatment for this condition.
