Famotidine in the treatment of acute urticaria.

Recent studies suggest that histamine H2-receptor antagonists may be useful in the treatment of urticaria. This study was conducted to determine whether famotidine, a H2 antagonist, is effective in the treatment of acute urticaria and compare its effect with that of the H1 antagonist diphenhydramine. In this prospective, double-blind, controlled trial, 25 patients with urticaria of less than 72 h duration were randomized to receive a single dose of either famotidine 20 mg i.m. or diphenhydramine 50 mg i.m. Prior to treatment and 30 min after treatment, patients rated pruritus and sedation using visual analogue scales, while physicians evaluated intensity of urticaria and percentage of body surface area involved by urticaria. Famotidine was found to reduce pruritus associated with acute urticaria, intensity of urticaria, and body surface area affected by urticaria without causing sedation. Famotidine was comparable to diphenhydramine in efficacy; however, there was a (nonsignificant) trend for diphenhydramine to be more effective than famotidine in the treatment of pruritus, and for famotidine to be more effective in the reduction of surface area of involvement. It is concluded that famotidine merits further investigation as a potential medication for treatment of urticaria.

Latanoprost-induced iris color darkening: a case report with long-term follow-up.

PURPOSE: To determine the effect on iris color of discontinuing latanoprost (LP) treatment in a patient with pronounced iris color darkening, and to assess the possible role of sympathetic innervation. METHODS: In a patient demonstrating pronounced iris color darkening in both eyes after treatment with LP for 6 months, magnified iris color photographs were taken at 3- to 6-month intervals for 5 years after discontinuation of LP treatment. Pupillary testing for sympathetic insufficiency was performed with cocaine 10% or hydroxyamphetamine 1%. RESULTS: The iris color did not appreciably change after discontinuing LP. The cocaine-induced increase in pupillary diameter was considerably greater for the control subject than for the patient who demonstrated the LP-induced color change. CONCLUSIONS: Latanoprost-induced iris color darkening does not appreciably change for several years after discontinuing treatment. Some eyes that show LP-induced darkening may have relative ocular sympathetic insufficiency.

Childhood sexual abuse as a risk factor for depression in women: psychosocial and neurobiological correlates.

OBJECTIVE: Depression is twice as common in women as in men, but the reason for this sexual dimorphism is unknown. This article reviews recent studies of the role of childhood sexual abuse in the subsequent development of major depressive disorder, and the biological and psychosocial mechanisms by which early stressors may contribute to adult-onset depression in women. Particular attention is paid to investigations of the long-term effects of early stress on hypothalamic-pituitary-adrenal (HPA) axis function. METHOD: Studies were identified by means of computerized and manual searches; further references were obtained from the bibliographies of reviewed articles. RESULTS: Childhood sexual abuse is associated with adult-onset depression in both men and women, and occurrence of such abuse is more common in girls than in boys. There is evidence from both animal and human studies that early stressors produce long-term dysregulation of the HPA axis similar to that seen in depressed patients and that such dysregulation results in a differential response to stressors in adulthood. In addition, it appears that the HPA axis in females may be more susceptible to stress-induced dysregulation, which might contribute to an increased vulnerability to depression in adulthood. CONCLUSIONS: Childhood sexual abuse is an important early stressor that may predispose individuals to adult-onset depression by means of dysregulation of the HPA axis. Investigation of the mechanisms mediating the relationship between childhood sexual abuse and adult-onset depression, and the study of gender differences in exposure to this and other stressors, may improve our understanding of the etiology of depressive illness in general.

Olanzapine addition in obsessive-compulsive disorder refractory to selective serotonin reuptake inhibitors: an open-label case series.

BACKGROUND: Despite the efficacy of selective serotonin reuptake inhibitors (SSRIs) in the treatment of obsessive-compulsive disorder, a significant number of patients show no or only partial remission of symptoms. Some evidence exists to suggest that risperidone augmentation can be helpful in treating this refractory group. The efficacy of other atypical antipsychotic agents, such as olanzapine, in augmenting SSRIs in refractory obsessive-compulsive patients has yet to be systematically investigated. METHOD: A series of 10 patients with DSM-IV obsessive-compulsive disorder showing significant residual symptoms following an adequate SSRI trial (12 weeks) were given open-label olanzapine augmentation for a minimum of an additional 8 weeks. Treatment response was assessed using the Yale-Brown Obsessive Compulsive Scale and the Clinical Global Impressions scale. RESULTS: Nine of the 10 patients in this series treated with olanzapine and an SSRI completed the 8-week augmentation trial. Of these, 4 demonstrated a complete remission or major improvement in obsessive-compulsive symptoms, 3 had partial remission, and 2 experienced no benefit. Nine patients experienced minimal adverse effects, primarily sedation, which did not interfere with continuing treatment. One patient discontinued olanzapine owing to excessive sedation. CONCLUSION: The results of this preliminary, open-label trial suggest that olanzapine may be effective in augmenting ongoing SSRI treatment for a portion of patients with obsessive-compulsive disorder refractory to SSRI treatment. Larger, placebo-controlled trials appear warranted to investigate the clinical efficacy and tolerability of olanzapine augmentation of SSRI treatment in SSRI-refractory obsessive-compulsive disorder.

Immunizations and travel.

Determining the appropriate immunizations for international travelers is a complex, multifaceted process. This article proposes a stepwise and systematic approach to the immunization needs of the traveler-patient. Vaccines for routine health maintenance as well as special issues of the elderly, pregnant, immunocompromised, and child are important in the initial evaluation. Specific travel immunizations (i.e., those for routine travel, those required by a country, those that are geographically indicated and immunizations for extended stays) comprise the remainder of the immunization interview. Health care providers should also be familiar with cost and risk statistics, both the risk of the traveler contracting an illness overseas and the risk of side effects from the vaccines themselves. With such cost-benefit analysis, the provider can offer the traveler immunizations as well as information.

Methadone levels in breast milk.

Two case reports of breastfeeding mothers on high doses of methadone and a literature review reveal that minimal transmission of methadone into breast milk occurs regardless of the mother's methadone dose. The current American Academy of Pediatrics recommendations that only women in drug treatment programs on less than 20 mg/day of methadone be advised to breastfeed should be reconsidered.

Case report: distribution of methamphetamine in a massive fatal ingestion.

A subject who apparently swallowed a baggie containing "crank" (methamphetamine) while being arrested, was admitted to hospital and then experienced a massive overdose of the drug. The subject went through a seizure with associated fixed dilated pupils, and a depressed pulse and blood pressure. His cardiac and respiratory problems could not be stabilized, and he died. Methamphetamine levels in central and peripheral blood, liver, bile, vitreous, gastric and urine were determined. Blood levels of greater than 60 mg/L, were found together with even higher levels in the bile, urine and gastric. These levels are discussed in terms of other fatal, non-fatal and recreational methamphetamine use.

Physician exposure to ionizing radiation during trauma resuscitation: a prospective clinical study.

A prospective study of emergency physician whole body and extremity exposure to ionizing radiation during trauma resuscitation over a three-month period was conducted. Radiation film badges and thermoluminescent dosimeter finger rings were permanently attached to leaded aprons worn by emergency medicine residents during all trauma resuscitations. One set of apron and finger ring dosimeters was designated for the resident who managed the airway and stabilized the neck, when necessary, during cervical spine radiography (A-CS resident). A separate set of dosimeters was designated for the resident supervising the resuscitation. During the study period, 150 major trauma patients requiring 481 radiographic studies were treated. The mean monthly cumulative whole body exposures were 136.7 +/- 85.0 and 103.3 +/- 60.3 mrem for A-CS and supervising residents, respectively. The mean weekly cumulative extremity exposures were 523.3 +/- 611.0 and 46.7 +/- 18.6 mrem for A-CS and supervising residents, respectively. Calculated whole body exposures per patient were 2.7 mrem for the A-CS resident and 2.1 mrem for the supervising resident. Calculated extremity exposures per patient were 41.9 +/- 48.9 and 3.7 +/- 1.5 mrem, respectively. To exceed the annual whole body exposure limit established by the National Council of Radiologic Protection, the A-CS resident, working 200 shifts per year, would have to treat 9.2 trauma patients per shift. To exceed the annual extremity exposure limit, the A-CS resident would have to treat 5.9 trauma patients per shift. Of note, European exposure limits are 10% of current US limits. We conclude that significant exposures may occur to physicians working in trauma centers and that the use of shielding devices is indicated.

Exposure of emergency medicine personnel to ionizing radiation during cervical spine radiography.

We studied the potential hazard of ionizing radiation exposure to health care workers who routinely stabilize the necks of trauma patients during cervical spine radiography. A clinical trauma model was developed using an Alderson RANDO Phantom artificial torso to simulate an actual patient. A radiation monitor was placed where a health care worker's fingers, hands, arms, and thyroid gland would be, and standard cervical spine radiographs were taken. The exposures to the finger positions then were repeated with the monitor inside a 0.5 mm lead-equivalent glove. The mean exposure to the finger for a single cross-table lateral radiograph was 174.5 mrem. The use of leaded gloves reduced this exposure to 0.3 mrem a 99.9% reduction). For a single series of lateral, anteroposterior, odontoid, and swimmer's views, the total mean measured unprotected exposure to the finger of the hand positioned nearest the radiographic tube was 681 mrem and the exposure to the finger of the opposite hand was 230 mrem. If these simulated exposures are indicative of actual patient situations, a health care worker who holds the head of a trauma patient four times each week with unshielded hands would receive more than twice the maximum allowable annual occupational radiation exposure to the extremities recommended by the National Council of Radiation Protection and Measurements. We conclude that health care workers who routinely stabilize the necks of trauma patients during cervical spine radiography may incur a radiation exposure risk and that 0.5-mm lead-equivalent gloves provide an effective barrier to ionizing radiation.
