OBJECTIVE:Epidural analgesia is associated with a four-to five-fold increase in noninfectious maternal fever in nulliparous women. Fever prophylaxis may safely reduce both unnecessary neonatal sepsis evaluations and the potential effect of fever on the fetus. STUDY DESIGN:We performed a randomized double-blind placebo-controlled study. Immediately after epidural placement, full-term nulliparas with a temperature of <99.51F received acetaminophen 650 mg or placebo, per rectum, every 4 hours. Tympanic membrane temperatures were measured hourly. Our power to detect an effect of acetaminophen treatment on maternal temperature over time was 90%. RESULTS:In all, 21 subjects were randomized to each arm. Treatment with acetaminophen did not impact maternal temperature curves. Fever >100.41F was identical in the acetaminophen and placebo groups (23.8%, p ¼ 1.0). Neonatal surveillance blood cultures did not reveal occult infection. CONCLUSIONS:Acetaminophen prophylaxis prevented neither maternal hyperthermia nor fever secondary to epidural analgesia, suggesting that the mechanism underlying fever does not include centrally mediated perturbations of maternal thermoregulation.
Background Women living with human immunodeficiency virus (WLHIV) have disproportionately high rates of squamous cell carcinoma of the anus compared with the general population of women. Anal high-grade squamous intraepithelial lesions (HSILs) precede anal cancer, and accurate studies of HSIL prevalence among WLHIV in the United States are lacking. Methods The AIDS Malignancy Consortium 084 study was a multicenter national trial to evaluate the prevalence of and risk factors for anal HSIL in a US cohort. Eligible participants were WLHIV aged ≥18 years with no history of anal HSIL. Study participants had an examination including collection of cervical/vaginal and anal specimens, followed by high-resolution anoscopy with biopsy. Results We enrolled 256 women with evaluable anal pathology. The mean age was 49.4 years, 64% women were non-Hispanic black, 67% were former or current smokers, and 56% reported ever having anal sex with a man. The median CD4 T-cell count was 664 cells/μL. The prevalence of anal histologic HSIL (hHSIL) was 27% (95% confidence interval [CI], 22%–33%). There was a strong concordance (240/254) between local and consensus pathologists for hHSIL vs less than hHSIL (κ = 0.86 [95% CI, .79–.93]). Current CD4 count of ≤200 cells/μL was the strongest predictor of consensus anal hHSIL diagnosis (adjusted odds ratio [aOR], 10.34 [95% CI, 3.47–30.87]). History of anoreceptive intercourse was also associated with hHSIL (aOR, 2.44 [95% CI, 1.22–4.76]). Conclusions The prevalence of anal hHSIL in WLHIV in the United States was 27% in this study where all participants received high-resolution anoscopy and biopsy.
Human immunodeficiency virus (HIV)-infected individuals have increased risk of anal intraepithelial neoplasia (AIN) and squamous cell carcinoma (SCC). Cytologic screening is invaluable in the detection of cervical neoplasia, therefore many clinicians have adopted anal cytology as part of anal cancer screening in patients at high-risk for anal neoplasia. The purpose of this study is to determine whether anal cytology is a valuable screening test for identifying AIN in HIV+ patients. The cohort included 228 HIV+ patients who underwent anal cancer screening with collection of 318 anal cytology specimens between January 2006 and December 2009. Of this group, 74 (32.5%) patients had associated anal biopsies within a 6-month period, with a total of 89 comparison cases. The anal cytology samples were classified using the 2001 Bethesda System terminology. The sensitivity of anal cytology in detecting ASC-US, AIN 1-3 or SCC was 93%. Cytology was 88% sensitive for detecting low-grade AIN (AIN 1), but only 20% sensitive for detecting high-grade AIN (AIN 2-3) or SCC. Atypical squamous cells of undetermined significance cases were distributed evenly between low- and high-grade AIN, with two cases having normal histology. Only six cases had negative cytology, all of which were associated with AIN on biopsy, for a false negative rate of 7%. Anal cytology is a good predictor of AIN, as confirmed by the high degree of sensitivity. However, there is poor correlation between the cytological and histological grade of AIN. Cytology underestimates the grade of dysplasia compared to the corresponding biopsy.
Cryptococcus neoformans is an encapsulated yeast that can cause primary pulmonary infections or disseminate and cause infections of the central nervous system, meninges, skin, and bone in the immunocompromised host. We present here an unusual case of an immunocompetent patient who had laryngitis due to C. neoformans that mimicked a laryngeal carcinoma on clinical examination and imaging studies.
