RESUMEN
IMPORTANCE: Resident fatigue has become a point of emphasis in medical education and its effects on otolaryngology residents and their patients require further study. OBJECTIVE: The purpose of our study was to evaluate the prevalence and nature of fatigue in otolaryngology residents, evaluate various quality of life measures, and investigate associations of increased fatigue with resident safety. STUDY DESIGN: Anonymous survey. SETTING: Internet based. PARTICIPANTS: United States allopathic otolaryngology residents. INTERVENTION: None. MAIN OUTCOME(S) AND MEASURES: The survey topics included demographics, residency structure, sleep habits and perceived stress. Responses were correlated with a concurrent Epworth Sleep Scale questionnaire to evaluate effects of fatigue on resident training and quality of life. RESULTS: 190 residents responded to the survey with 178 completing the Epworth Sleep Scale questionnaire. Results revealed a mean Epworth Sleep Scale score of 9.9±5.1 with a median of 10.0 indicating a significant number of otolaryngology residents are excessively sleepy. Statistically significant correlations between Epworth Sleep Scale and sex, region, hours of sleep, and work hours were found. Residents taking in-house call had significantly fewer hours of sleep compared to home call (p=0.01). Residents on "head and neck" (typically consisting of a large proportion of head and neck oncologic surgery) rotations tended to have higher Epworth Sleep Scale and had significantly fewer hours of sleep (p=.003) and greater work hours (p<.001). Additionally, residents who reported no needle stick type incidents or near motor vehicle accidents had significantly lower mean Epworth Sleep Scale scores. Only 37.6% of respondents approve of the most recent Accreditation Council for Graduate Medical Education work hour restrictions and 14% reported averaging greater than 80hours of work/week. CONCLUSION AND RELEVANCE: A substantial number of otolaryngology residents are excessively sleepy. Our data suggest that the effects of fatigue play a role in resident well-being and resident safety.

Trust in one's health care provider, trust in the health care system in general, and even trust in one's community affects engagement in HIV-related health care. This article examines the issue of trust among a random sample of HIV-infected individuals residing in Mississippi, an area hard-hit by the HIV/AIDS epidemic. Five constructs based on survey responses from these individuals were developed: (1) trust in one's provider to offer the best possible medical care, (2) trust in one's provider to protect patient privacy, (3) willingness to disclose HIV status to one's provider, (4) trust in the health care system, and (5) trust in one's community. Findings suggest that interventions to improve trust in providers to deliver the highest quality of care should be targeted to young people, African Americans, and the more highly educated. Interventions to increase trust in providers to protect privacy should focus on creating and strengthening social support groups or networks that build relationships and foster trust. Interventions aimed to increase community trust also should be targeted to young people. This information is useful to researchers, policy makers, health care providers, and organizations interested in prioritizing interventions and strategies that have the greatest potential to reduce health disparities in HIV diagnosis and treatment in the Deep South.

BACKGROUND: African-American ancestry, hypokalemia, and QT interval prolongation on the electrocardiogram are all risk factors for sudden cardiac death (SCD), but their interactions remain to be characterized. SCN5A-1103Y is a common missense variant, of African ancestry, of the cardiac sodium channel gene. SCN5A-1103Y is known to interact with QT-prolonging factors to promote ventricular arrhythmias in persons at high risk for SCD, but its clinical impact in the general African-American population has not been established. METHODS: We genotyped SCN5A-S1103Y in 4,476 participants of the Jackson Heart Study, a population-based cohort of African Americans. We investigated the effect of SCN5A-1103Y, including interaction with hypokalemia, on QT interval prolongation, a widely-used indicator of prolonged myocardial repolarization and predisposition to SCD. We then evaluated the two sub-components of the QT interval: QRS duration and JT interval. RESULTS: The carrier frequency for SCN5A-1103Y was 15.4%. SCN5A-1103Y was associated with QT interval prolongation (2.7 milliseconds; P < .001) and potentiated the effect of hypokalemia on QT interval prolongation (14.6 milliseconds; P = .02). SCN5A-1103Y had opposing effects on the two sub-components of the QT interval, with shortening of QRS duration (-1.5 milliseconds; P = .001) and prolongation of the JT interval (3.4 milliseconds; P < .001). Hypokalemia was associated with diuretic use (78%; P < .001). CONCLUSIONS: SCN5A-1103Y potentiates the effect of hypokalemia on prolonging myocardial repolarization in the general African-American population. These findings have clinical implications for modification of QT prolonging factors, such as hypokalemia, in the 15% of African Americans who are carriers of SCN5A-1103Y.

BACKGROUND: The biochemical pathways underlying alcohol abuse and dependence are not well understood, although brain cell loss and neurotoxicity have been reported in subjects with alcohol dependence. Monoamine oxidase B (MAO B; an enzyme that catabolizes neurotransmitters such as dopamine) is consistently increased in this psychiatric illness. MAO B has been implicated in the pathogenesis of alcohol dependence and alcohol-induced brain neurotoxicity. Recently, the cell growth inhibitor protein, Kruppel-like factor 11 (KLF11), has been reported to be an MAO transcriptional activator. KLF11 is also known as TIEG2 (transforming growth factor-beta-inducible early gene 2) and mediates apoptotic cell death. This study investigates the protein expression of KLF11 and its relationship with MAO B using human postmortem prefrontal cortex from subjects with alcohol dependence. METHODS: Twelve subjects with alcohol dependence and the respective psychiatrically normal control subjects were investigated. Expression of KLF11 and MAO B proteins in the prefrontal cortex was measured by Western blot analysis. Correlation studies involving KLF11 and MAO B protein expression were performed. Localization of KLF11 in the human prefrontal cortex was also determined by immunohistochemistry. RESULTS: Levels of KLF11 protein were significantly increased by 44% (p < 0.03) in the postmortem prefrontal cortex of subjects with alcohol dependence as compared to age- and gender-matched, psychiatrically normal control subjects. Furthermore, KLF11 levels were significantly and positively correlated with both the increased MAO B protein levels and blood alcohol content in alcohol-dependent subjects. In addition, KLF11 protein expression was visualized in both neuronal and glial cells. CONCLUSIONS: This novel study shows the important role of KLF11, an MAO transcriptional activator, in human alcohol dependence. It further supports that the KLF11-MAO B cell death cascade may contribute to chronic alcohol-induced brain damage. This argues a case for KLF11-MAO B inhibition as a novel therapeutic strategy that may impact this highly prevalent illness.

Using funds provided by the Ryan White Care Act, we conducted a statewide needs assessment of persons living with HIV/AIDS (PLWHA) in Mississippi as required by provisions of the Act. Most published research addressing access to care for PLWHA is based on convenience samples of persons already accessing care in specified clinic locations. For this study of a single state with a well-established mandatory reporting system, we conducted a cross-sectional study interviewing a random sample of PLWHA across the state of Mississippi. The Mississippi State Department of Health has maintained the Mississippi HIV/AIDS Reporting System since its inception in 1980. The database tracks all reported cases of HIV+ cases and includes name, age, last-known address, and other contact information. The sample was selected from a frame of all recorded PLWHA in Mississippi at that time, regardless of their association with care facilities. The purpose of this article is to describe the design and methodology of this study, difficulties encountered in locating this hard-to-reach population, multimethod recruiting strategies and outcomes, and lessons learned. Locating participants using a truly random sample from a mandatory reporting database was resource intensive. However, data collected as a result of these efforts have provided invaluable information on a number of topics important to PLWHA.

The objective of this cross-sectional study was to describe the relationship between access to care and health-related quality of life (HRQOL) for persons living with HIV/AIDS (PLWHA) in Mississippi by administering a statewide survey. A random probability sample of PLWHA was derived from the Mississippi State Department of Health's communicable disease tracking system. Interviews were conducted with 220 PLWHA to collect data on access to care, demographic and social characteristics, and HRQOL. Overall, most participants had access to care and reasonable HRQOL. Multivariate and univariate analyses were performed to measure associations between access to care and HRQOL. Univariate analyses showed that age, income, social networks, severity of disease, having been prescribed medications, and having experienced problems accessing care to be significantly associated with HRQOL scales. Multivariate analysis of variance models further demonstrated low-income level, having experienced problems accessing care, and having been prescribed antiretroviral medications to be significantly associated with HRQOL. Reducing barriers is a major factor in improving quality of life. This study provides needed insight into the relationship between access to care and HRQOL among PLWHA in Mississippi, which could be valuable to public health planners to help them better understand how to make the greatest impact on HRQOL.

A statewide needs assessment of persons living with HIV/AIDS (PLWHA) was conducted to determine what is known about access to care, utilization of services, and perceived barriers to receiving care and services. Our objective was to determine which needs were being met or unmet among PLWHA in Mississippi to provide a better understanding of how effectively to allocate funding to provide for the needs of that group. In this cross-sectional study, a true random sample of PLWHA in Mississippi was interviewed in 2005-2006. Questions were asked to identify opinions about respondents' experiences with 23 health care services and 30 public or private assistance services. The kappa statistic was used to measure agreement between level of services needed and level of services provided. Services with the lowest kappa scores revealed which services were being either mostly unmet, or even overly met. Greatest service needs were HIV viral load test, Pap smear, CD4/T-cell count test, and medication for HIV/AIDS, which were reasonably well met. The most significantly unmet needs were dental care and dental exams, eye care and eye exams, help paying for housing, subsidized housing assistance, mental health therapy or counseling, access to emotional support groups, and job placement or employment. Overly met services included medical care at a physician's office or clinic and free condoms. This study identified needs perceived to be significantly unmet by PLWHA, as well as areas that were perceived to be adequately or overly met. This information may be used to target areas with the greatest impact for improvement and provide insight into how to effectively allocate health care resources and public/private assistance.

PURPOSE: To evaluate risk factors for sclerotomy leakage in 23-gauge sutureless pars plana vitrectomy in 219 patients. METHODS: Nested case-control study involving 48 patients with wound leaks (visible on-table sclerotomy leakage requiring sutures) and 171 control subjects without wound leaks. Patients received either a conventional sclerotomy incision at 45°, which was then changed to 90° midincision, or an extremely oblique sclerotomy incision (OSI) at 10°, which was then changed to 30° midincision. Risk factors studied included age, gender, laterality, surgical duration, sclerotomy incision (OSI vs. conventional sclerotomy incision), preoperative diagnosis (macular vs. nonmacular), history of vitrectomy, and primary surgeon (attending vs. supervised resident). RESULTS: Multivariate logistic regression analysis found significant (P ≤ 0.05) protective factors for wound leakage including OSI, macular preoperative diagnosis, no previous vitrectomy, and female gender. Surgical duration at least 45 minutes was considered a borderline risk factor. CONCLUSION: Using an extremely OSI versus a conventional sclerotomy incision reduces the incidence of wound leakage postoperatively because of its self-sealing effect. Other factors that contribute to wound leakage, such as increased surgical duration and nonmacular diagnosis, may be indirect measurements of extensive trocar rotation, causing wound leakage despite the use of an OSI.

We assessed pregnancy outcomes for patients with HELLP syndrome (hemolysis; elevated liver enzymes; low platelet count) with and without concurrent eclampsia. We performed a retrospective investigation of data spanning three decades of patients with class 1 or 2 HELLP syndrome with concurrent eclampsia (HELLP + E) and patients with HELLP syndrome without eclampsia. Data were analyzed by appropriate tests for continuous or categorical outcomes with differences considered significant if P < 0.05. During 1981 to 1996 and 2000 to 2006, there were 693 patients with class 1 or 2 HELLP syndrome; altogether, 70 patients had HELLP + E. The only demographic difference was greater nulliparity in HELLP + E patients. Otherwise, inconsistent and clinically insignificant differences were observed between groups. Despite the relatively large size of the study groups, we were unable to detect a significant worsening of maternal or perinatal outcome in HELLP + E patients compared with HELLP patients. In our experience, eclampsia does not appear to contribute a significant adverse impact upon the course or outcome of HELLP syndrome pregnancies.

The relationship between serotonin (5-HT) and major depressive disorder (MDD) has been extensively studied but certain aspects are still ambiguous. Given the evidence that 5-HT neurotransmission is reduced in depressed subjects, it is possible that one or more of the 5-HT regulators may be altered in the dorsal raphe nucleus (DR) of depressed subjects. Candidates that regulate 5-HT synthesis and neuronal activity of 5-HT neurons include intrinsic regulators such as tryptophan hydroxylase 2, 5-HT autoreceptors, 5-HT transporter and transcription factors, as well as afferent regulators such as estrogen and brain-derived neurotrophic factor. The present study was designed to quantify mRNA concentrations of the above 5-HT regulators in an isolated population of 5-HT-containing DR neurons of MDD subjects and gender-matched psychiatrically normal control subjects. We found that mRNA concentrations of the 5-HT1D receptor and the transcription factors, NUDR and REST, were significantly increased in DR-captured neurons of female MDD subjects compared to female control subjects. No significant differences were found for the transcripts in male MDD subjects compared to male controls. This study reveals sex-specific alterations in gene expression of the pre-synaptic 5-HT1D autoreceptors and 5-HT-related transcription factors, NUDR and REST, in DR neurons of women with MDD.

Serotonin1A (5-HT(1A)) receptors are reported altered in the brain of subjects with major depressive disorder (MDD). Recent studies have identified transcriptional regulators of the 5-HT(1A) receptor and have documented gender-specific alterations in 5-HT(1A) transcription factor and 5-HT(1A) receptors in female MDD subjects. The 5' repressor element under dual repression binding protein-1 (Freud-1) is a calcium-regulated repressor that negatively regulates the 5-HT(1A) receptor gene. This study documented the cellular expression of Freud-1 in the human prefrontal cortex (PFC) and quantified Freud-1 protein in the PFC of MDD and control subjects as well as in the PFC of rhesus monkeys chronically treated with fluoxetine. Freud-1 immunoreactivity was present in neurons and glia and was co-localized with 5-HT(1A) receptors. Freud-1 protein level was significantly decreased in the PFC of male MDD subjects (37%, p=0.02) relative to gender-matched control subjects. Freud-1 protein was also reduced in the PFC of female MDD subjects (36%, p=0.18) but was not statistically significant. When the data was combined across genders and analysed by age, the decrease in Freud-1 protein level was greater in the younger MDD subjects (48%, p=0.01) relative to age-matched controls as opposed to older depressed subjects. Similarly, 5-HT(1A) receptor protein was significantly reduced in the PFC of the younger MDD subjects (48%, p=0.01) relative to age-matched controls. Adult male rhesus monkeys administered fluoxetine daily for 39 wk revealed no significant change in cortical Freud-1 or 5-HT(1A) receptor proteins compared to vehicle-treated control monkeys. Reduced protein expression of Freud-1 in MDD subjects may reflect dysregulation of this transcription factor, which may contribute to the altered regulation of 5-HT(1A) receptors observed in subjects with MDD. These data may also suggest that reductions in Freud-1 protein expression in the PFC may be associated with early onset of MDD.

BACKGROUND: The incidence of vaginal incision dehiscence after total hysterectomy has been reported to be higher with laparoscopic than with open surgery, but the data are limited. This report documents a case and reviews the literature in order to further estimate the differences in incidence by route of hysterectomy. CASE: A 45-year-old woman underwent successful vaginal repair of postcoital cuff dehiscence with small bowel evisceration 67 days after total laparoscopic hysterectomy and bilateral salpingo-oophorectomy for menometrorhagia. CONCLUSION: Seven observational studies were identified. The comparison of total laparoscopic to robotic hysterectomy was not statistically significant, nor was the comparison of total abdominal to vaginal hysterectomy. However, the incidence of dehiscence for laparoscopic procedures was statistically greater than the incidence for open surgery (p value <0.001).

A review of pregnancy-associated thrombotic thrombocytopenic purpura (TTP) in 166 pregnancies was undertaken using 92 English-language publications from 1955 to 2006. Initial and recurrent TTP presents most often in the second trimester (55.5%) after 1-2 days of signs/symptoms; postpartum TTP usually occurs following term delivery. TTP with preeclampsia (n = 28) exhibits 2-4 times higher aspartate aminotransferase (AST) values and lower total lactate dehydrogenase (LDH) to AST ratios (LDH to AST ratio = 13:1), compared with TTP without preeclampsia (LDH to AST ratio = 29:1). Maternal mortality is higher with initial TTP (26% vs 10.7%), especially with concurrent preeclampsia (44.4% vs 21.8%, P < .02). Although maternal mortality with TTP has substantially declined when plasma therapy is utilized, delay of diagnosis and therapy for initial TTP confounded by preeclampsia/hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome remains a significant maternal-perinatal threat. Rapid and readily available laboratory testing to quickly diagnose TTP and HELLP syndrome/preeclampsia is desperately needed to improve care.

AIM: To identify the predictors of vitamin D deficiency in patients with and without inflammatory bowel disease (IBD). METHODS: Patients with ulcerative colitis (UC) or Crohn's disease (CD) related diagnostic codes who received medical care at University of Mississippi Medical Center between July 2012 and 2015 were identified. After thorough chart review, we identified patients with biopsy proven IBD who had also been tested for serum 25-hydroxyvitamin D [25(OH)D] concentration. We compared these patients to a previously studied cohort of healthy controls who also had vitamin D concentration checked. Logistic regression analysis was performed to determine the association between vitamin d deficiency and UC, CD, race, age, gender and body mass index (BMI). RESULTS: We identified 237 patients with confirmed IBD. Of these, only 211 had a serum 25(OH)D concentrations available in the medical record. The group of healthy controls consisted of 98 individuals with available serum 25(OH)D concentration. 43% of IBD patients were African American (AA). Patients with CD were more likely to have vitamin D concentration checked. Bivariate analysis showed that AA (51% vs 21%, P = 0.00001), subjects with BMI >30 kg/m2 (39% vs 23% P = 0.01) and CD (40% vs 26%, P = 0.04) were more likely to be vitamin D deficient than vitamin D sufficient. Those with Age > 65 were more likely to be vitamin D sufficient (46% vs 15%, P = 0.04). Multiple regression showed that only BMI > 30 kg/m2 and AA race are associated with vitamin D deficiency. CONCLUSION: BMI > 30 kg/m2 and AA race are predictive of vitamin D deficiency. Gender, age and diagnosis of IBD are not predictive of vitamin D deficiency.

AIMS: Mulberry leaves have been used anecdotally in Asia to treat many disease states, including glucose abnormalities. Animal and human studies illustrate potential benefit of mulberry leaf extract (MLE) in type 2 diabetes mellitus (DM2). The purpose of this study is to evaluate the glycemic and safety effects of MLE in patients with DM2. MATERIALS & METHODS: This randomized, double-blind, placebo-controlled pilot study evaluated MLE (1000mg standardized) versus matching placebo given three times daily with meals. Patients (n=24) were included if they had DM2 on single or combination oral therapy with a stable hemoglobin A1C (A1C). A 2-week placebo run-in (baseline) was followed by initiation of randomized medication for 3 months. Primary endpoints were change in A1C and self-monitoring blood glucoses (SMBG). Safety was also evaluated. RESULTS: Of 24 patients enrolled, 17 patients completed the study. Post-prandial SMBG was significantly decreased at 3 months in the MLE group versus baseline (16.1%; p<0.05). This improvement in post-prandial SMBG persisted when compared to placebo (18.2%; p<0.05). A1C decreased from 7.30% at baseline to 6.94% in the MLE group but did not reach statistical significance (p=0.079). There was no difference in A1C between MLE and placebo. A significant 15% increase occurred in serum creatinine when the MLE group was compared to baseline or placebo (p<0.05 for both). There was no significant effect on weight, fasting SMBG, blood pressure, hypoglycemia, or other safety evaluation markers. CONCLUSIONS: These results suggest that mulberry leaf extract may be a useful complementary mealtime glucose option for patients with DM2. ClinicalTrials.gov Identifier NCT00795704.

EDUCATIONAL OBJECTIVE: At the conclusion of this paper, the participants should be able to identify, compare, and discuss the natural history of complications of mandible fractures and repair. OBJECTIVES: To analyze factors affecting the incidence of long-term complications after the repair of mandible fractures. To determine whether the use of antibiotics at any time in the course of treatment impacted the development of complications. STUDY DESIGN: Retrospective medical record review. METHODS: Medical records for patients with mandibular fractures treated surgically over a 5 year period were reviewed for demographics, history of substance abuse, etiology, location of fracture, any associated facial injury, type and timing of repair, pre-, peri-, and postoperative antibiotic treatment, length of hospitalization, and lag time to repair. The development of infectious and other complications after surgery, specifically, the development of abscesses, fistulae, mal/nonunion, hardware exposure, or extrusion, were recorded. RESULTS: Of 273 subjects, 56 fractures were repaired using open reduction internal fixation (ORIF) alone, 112 mandibulomaxillary fixation (MMF), and 105 with a combination of MMF and ORIF. Eighteen (6.6%) patients developed an infectious or related long-term complication. These included abscess (n = 4), infected hardware (n = 1), mal/nonunion (n = 8), and hardware exposure/extrusion (n = 9). Smoking and alcohol abuse (P = .021) and the use of plating techniques (P = .04) correlated with a higher incidence of long-term complications. Patient age, sex, location and etiology of fracture, associated facial injury, lag time to repair, length of hospitalization, and the use of antibiotics at any time after injury or repair were unrelated to the development of complications. CONCLUSIONS: The development of infection, nonunion, and related complications after the repair of mandibular fractures correlates with a history of tobacco and alcohol use and ORIF of multiple fractures, but there were no statistically significant relationships to patient demographics, fracture site, lag time to repair, length of hospitalization, or the use of antibiotics. In this series, antibiotic therapy appears to have had no impact on the development of postoperative complications.

Confidence intervals, in general, have become an important aspect of reporting statistical results. In particular, interval estimators for binomial proportions have been studied extensively in recent literature. The large-sample Wald intervals are known to perform poorly, but the Wilson intervals have been shown to perform well in a variety of situations. One criticism is the relative difficulty of computing the Wilson or quadratic intervals in comparison to the Wald intervals. We offer a computational formula for the Wilson intervals that is a weighted estimator of the observed proportion, p, and that based on an uninformative prior, 1/2. This contribution enhances our understanding of the coverage behavior of the Wilson intervals. In addition, we contrast the Wilson intervals with other well-known intervals for the case of zero successes.

BACKGROUND: Saline nasal irrigations (SNI) are an important adjunct in the treatment of rhinosinusitis, and many patients prepare and store these solutions in their homes without an awareness of the potential for contamination. The objectives of this study were to determine if such contamination occurs and the effect of preparation methods on contamination. METHODS: Stock solutions of various tonicities and pHs were prepared using boiled, bottled, and distilled water (n = 57). The solutions were stored at ambient temperature or refrigerated for 1 week. Each day, 50 mL of the solutions were decanted to simulate transferring the stock solution into an irrigation vector. Cultures of the stock solutions were taken on days 1, 3, and 7. RESULTS: Overall contamination rate was 35.1%. The boiled water solutions were more likely to demonstrate bacterial growth (p < 0.001), as were those that were hypotonic (p = 0.046). pH had no significant effect (p = 0.127). Growth occurred as early as 24 hours after solution preparation. Pathogenic species isolated were Staphylococcus aureus, Moraxella sp, Sphingomonas paucimobilis, Acinetobacter junii, Methylobacterium sp, and Brevundimonas diminuta. No bacterial growth occurred in refrigerated solutions (p = 0.008). CONCLUSION: Pathogenic bacterial growth can occur in a short period of time in homemade SNI solutions with routine handling. Solutions should be refrigerated if possible. If solutions are to be stored at ambient temperature, they should be either isotonic or hypertonic and prepared from bottled or distilled water.

OBJECTIVE: We compared maternal outcomes for patients with severe preeclampsia who were managed postpartum with or without adjunctive intravenous dexamethasone. METHODS: This study was a randomized, blinded placebo-controlled clinical trial comparing the use of dexamethasone postpartum (10 mg-10 mg-5 mg-5 mg intravenously every 12 hours) with a saline control in patients with severe preeclampsia. The Student t and chi(2) tests were used for data analysis, with P < .05 considered significant. RESULTS: Data from 157 patients (77 patients receiving dexamethasone, 80 patients receiving placebo) who were treated during 2000-2003 were analyzed. Demographics, diagnostic criteria, baseline laboratory values, and postpartum outcomes were similar between groups. Although dexamethasone-treated patients had fewer returns (6.5% compared with 11.3%) to the labor/delivery/recovery unit for uncontrolled hypertension than control patients, no significant differences were found in blood pressure, antihypertensive requirements, laboratory values, length of hospitalization, interval urine output at 48 hours postpartum, or major maternal morbidity. Two control patients developed hemolysis, elevated liver enzymes, low platelets syndrome. CONCLUSION: Adjunctive use of intravenous dexamethasone for postpartum patients with severe preeclampsia does not reduce disease severity or duration. LEVEL OF EVIDENCE: I.

OBJECTIVE: This investigation was undertaken to estimate whether a brief postpartum course of furosemide for patients with preeclampsia benefits recovery and shortens hospitalization by enhancing diuresis, lessening severe hypertension, and reducing the need for antihypertensive therapy. METHODS: Two hundred sixty-four patients with preeclampsia were enrolled. After spontaneous onset of postpartum diuresis and discontinuation of intravenous magnesium sulfate, patients were randomly assigned to receive either no therapy or 20 mg oral furosemide daily for 5 days with oral potassium supplementation. Patient outcomes were compared between treatment groups with regard to classification of hypertensive disease. RESULTS: Only postpartum patients with severe preeclampsia (n = 70) who received furosemide compared with controls had significantly lower systolic blood pressure by postpartum day 2 (142 +/- 13 mm Hg compared with 153 +/- 19 mm Hg, P < .004) and required less antihypertensive therapy during hospitalization (14% compared with 26%, P = .371) and at discharge (6% compared with 26%, P = .045). No benefit was shown for patients with mild preeclampsia (n = 169) or superimposed preeclampsia (n = 25). Neither length of hospitalization nor frequency of delayed postpartum complications was positively affected by the intervention. CONCLUSION: Brief postpartum furosemide therapy for patients with severe preeclampsia seems to enhance recovery by normalizing blood pressure more rapidly and reducing the need for antihypertensive therapy. Shortening of hospitalization and reduction of delayed postpartum complications were not benefitted.
