Daily gentamicin using ideal body weight demonstrates lower risk of postpartum endometritis and increased chance of successful outcome compared with traditional 8-hour dosing for the treatment of intrapartum chorioamnionitis.

Background: Clinical chorioamnionitis complicates approximately 1-4% of pregnancies overall. Although universal agreement does not exist regarding the antibiotic regimen of choice, most studies have evaluated intravenous ampicillin dosed at 2 g every 6 hours plus gentamicin dosed every 8 hours. Only three studies have examined daily gentamicin for the treatment of intrapartum chorioamnionitis and thus is insufficiently investigated. Objective: This study seeks to determine whether daily dosing of gentamicin using ideal body weight for the treatment of intrapartum chorioamnionitis is more or equivalently efficacious when compared to traditional 8-hour dosing regimens. Materials and methods: We conducted a retrospective cohort study and reviewed charts on all women receiving treatment for intrapartum chorioamnionitis, which included intravenous gentamicin daily dosing calculated using 5 mg/kg ideal body weight or receiving traditional every 8 hours dosing of gentamicin at two large academic centers. Our primary outcomes were resolution of infection following delivery without the development of maternal endometritis and/or neonatal sepsis. Baseline characteristics were compared between dosing groups using Welch two-sample t-tests for continuous variables, uncorrected X2 test and exact binomial 95% confidence intervals. We calculated the risk ratios of each outcome in the ideal versus traditional dosing groups using modified Poisson regression, both crude and adjusted. Adjusted models were controlled for variables determined to be potential confounders, which included BMI, diabetes mellitus, gestational blood pressure >140/90, group ß-Streptococcus status, race, advanced maternal age (>34 y), and parity. Results: The study included 500 patients with 255 patients receiving daily dosing of gentamicin and 245 receiving traditional dosing of gentamicin. Of the patients receiving daily gentamicin compared to traditional dosing, 95.7% (95% CI 94.9-96.6%) achieved the primary outcome versus 92% (95% CI 90.8 - 93.2%), 2.4% (95% CI 1.8-3%) developed endometritis versus 5.6% (4.5-6.7%), 1.6% (95% CI 1.1-2.1%) delivered neonates with sepsis versus 3.3% (CI 2.5-4.1%), and 36.9% required cesarean delivery versus 41.4%. In crude analysis, compared to traditional dosing, IDW daily dosing was associated with a lower risk of postpartum endometritis (RR 0.42, 95% CI 0.16-1.10, p = .032). After adjusting for BMI, diabetes mellitus, gestational blood pressure >140/90, group ß-Streptococcus status, race, advanced maternal age (>34 y), and parity, the IDW daily dosing group had a 5% greater chance of successful outcome (RR 1.05, 95% CI 1.00-1.10, p = .046) and a 64% lower risk of endometritis (RR 0.35, 95% CI 0.15-0.83, p = .017). Conclusion: Daily dosing of gentamicin using ideal body weight is associated with a lower risk of postpartum endometritis and high chance of a successful outcome in the treatment of intrapartum chorioamnionitis compared with traditional 8-hour dosing in our ethnically diverse, urban population and thus may be considered a superior option to every 8 hours dosing regimens.

Osteopathic Evaluation of Urinary Retention Caused by Atypical Presentation of Invasive Cervical Cancer Mimicking Primary Urothelial Tumor.

Cancer of the uterine cervix is the third most common gynecologic cancer diagnosis and cause of death among gynecologic cancers in the United States. Cervical cancer is frequently asymptomatic until it reaches a locally advanced stage. The authors present a case of urinary retention caused by an atypical presentation of invasive cervical cancer mimicking primary urothelial tumor. The patient was evaluated by a multidisciplinary team, with osteopathic structural examination, intraoperative examination, surgical resection, and histopathologic analysis.

Pelvic Tuberculosis Diagnosed during Operative Laparoscopy for Suspected Ovarian Cancer.

BACKGROUND: While the combination of a pelvic mass, very high serum level of CA-125, chest adenopathy, and ascites is concerning for advanced-stage ovarian cancer, the etiology of such a presentation can be due to disseminated pelvic tuberculosis. CASE: A 67-year-old para 2 African-American woman presented with abdominal pain and shortness of breath. Subsequent CT and MR imaging demonstrated chest adenopathy, a pelvic mass, omental caking, and ascites. The patient underwent diagnostic laparoscopy with biopsy revealing noncaseating granulomas and subsequent tissue culture revealed Mycobacterium tuberculosis. The patient was diagnosed with disseminated pelvic tuberculosis and multidrug therapy was initiated. CONCLUSION: Pelvic tuberculosis can mimic advanced-stage ovarian cancer; thus obtaining a tissue sample may be beneficial to more appropriately direct treatment and planning for neoadjuvant therapies given the ineffectiveness of extensive surgical procedures in treating pelvic tuberculosis commonly employed in the treatment of advanced-stage ovarian cancer.

Variations in Progression and Regression of Precancerous Lesions of the Uterine Cervix on Cytology Testing Among Women of Different Races.

Background: Although not incorporated into current cervical cancer screening guidelines, racial differences are known to persist in both occurrence of and outcomes related to cervical cancer. Objective: To compare the differences in progression and regression of precancerous lesions of the uterine cervix on cervical cytologic analysis among women of different races who adhered to cervical cancer screening recommendations and follow-up. Methods: Retrospective cohort study comparing differences in precancerous lesion diagnoses for patients receiving adequate evaluation according to the American Society for Colposcopy and Cervical Pathology guidelines. The authors fit Markov multistate models to estimate self-reported race-specific expected wait times and hazard ratios for each possible regression and progression and compared a race model with an intercept-only model using a likelihood ratio test. Results: The sample included 5472 women receiving a Papanicolaou test between January 2006 and September 2016, contributing a total of 24,316 person-years of follow-up. Of 21 hazard ratios tested for significance, the following 4 hazard ratios (95% CIs) were statistically significant: atypical squamous cells of undetermined significance (ASC-US) progression to low-grade squamous intraepithelial lesion (LSIL) for Hispanic patients (0.72; 95% CI, 0.54-0.96); LSIL regression to ASC-US for Hispanic patients (1.55; 95% CI, 1.04-2.31), LSIL regression to ASC-US for Asian patients (1.91; 95% CI, 1.08-3.36), and high-grade squamous intraepithelial lesion regression to LSIL for black patients (0.39; 95% CI, 0.16-0.96). There is an observed trend that all racial groups other than white had a slower rate of progression from ASC-US to LSIL, with Hispanics having demonstrated the slowest rate from ASC-US to LSIL. Hispanics also demonstrated the fastest rate from LSIL to HSIL when compared with all other race categories. In regressions, blacks had the slowest rate of regression from HSIL to LSIL, and Asians had the fastest rate from LSIL to ASC-US. The Hispanic group demonstrated the fastest expected progression (17.6 months; 95% CI, 11.5-25.5), as well as the fastest regression (27.6 months; 95% CI, 21.5-35.6), and the black group has the slowest expected times for both progression (28.1 months; 95% CI, 14.6-47.2) and regression (49 months; 95% CI, 29.1-86.2). The number of visits (1 vs ≥2) in the study was differentially distributed both by race (P=.033) and by last diagnosis (P<.001). Conclusion: Variations in precancerous lesions of the uterine cervix are not uniform across races.

Ruptured Primary Omental Pregnancy Mimicking Adnexal Implantation.

Ectopic pregnancies occur when the implantation of a fertilized ovum occurs outside of the endometrial cavity. The majority of ectopic pregnancies encountered in clinical practice are located within the fallopian tube. Abdominal pregnancies represent 1% of all ectopic pregnancies. Primary omental pregnancy, in which the extrauterine site of implantation is the greater omentum, is the least common form of abdominal pregnancy. The rarity of an ectopic pregnancy in the omentum and the absence of clinical symptoms often delays diagnosis and proper identification before rupture. The authors describe the case of a 23-year-old woman who had hemoperitoneum from a ruptured omental ectopic pregnancy that mimicked adnexal implantation. Her omental pregnancy was diagnosed through intraoperative exploration and osteopathic structural examination findings.

Somatic Dysfunction in the Diagnosis of Uncommon Ectopic Pregnancies: Surgical Correlation and Comparison With Related Pathologic Findings.

BACKGROUND: Ectopic pregnancies occur when the implantation of a fertilized ovum occurs outside the endometrial cavity. Such pregnancies occur in approximately 1.5% to 2.0% of all pregnancies and cause 6% of maternal deaths. OBJECTIVES: To evaluate osteopathic structural examination (OSE) findings in patients with ectopic pregnancies of uncommon locations and to establish the utility of these findings in the diagnosis of these ectopic pregnancies. METHODS: In this prospective case series, a focused OSE was performed on each patient with an ectopic pregnancy at her initial presentation after the patient history but before other diagnostic or laboratory tests were performed and surgical treatment was initiated. Chapman reflex points (CRPs) were evaluated pre- and postoperatively. For comparison, patients who had otherwise normal first pregnancies, underwent elective postpartum bilateral tubal ligation, or had simple ovarian cysts were also included and received OSEs. RESULTS: Seven cases with ectopic pregnancies outside the fallopian tube were included. Two primary ovarian pregnancies and 1 heterotopic pregnancy (uterine and ovarian) had somatic dysfunction at the T10-T11 spinal levels and CRPs posterior for the ovary, 1 primary omental pregnancy with somatic dysfunction at the T9-T12 spinal levels and CRPs anterior and posterior for the ileum and jejunum, and 1 tubal pregnancy with somatic dysfunction at the T10-L1 spinal levels and CRPs anterior and posterior for the fallopian tube. Two cornual ectopic pregnancies were not associated with unique findings. These somatic dysfunctions and CRP findings appear to be distinct from those of comparison cases, including first pregnancies at any trimester, simple ovarian cysts, and elective bilateral tubal ligation. CONCLUSION: The OSE findings demonstrated in these cases aided in the final diagnosis and thus can potentially prove helpful in cases of ovarian, tubal, and omental pregnancies to provide clues to abnormal ectopic pregnancy locations where diagnostic imaging results are insufficient or equivocal. Osteopathic structural examinations may allow osteopathic physicians to better prepare for treatment approaches, including surgery.

Osteopathic Approach to the Diagnosis of Appendiceal Mucinous Cystadenocarcinoma Mimicking Primary Ovarian Malignant Neoplasm.

The fifth leading cause of cancer-related deaths among women in the United States is ovarian cancer. An estimated 21,980 new cases and 14,270 estimated deaths occurred nationwide in 2014. More than two-thirds of cases of ovarian cancer are diagnosed at stage III or IV when the peritoneal cavity or other organs are affected. Primary appendiceal malignant neoplasms may mimic advanced-stage ovarian cancer and can be misdiagnosed because of its presentation as a palpable adnexal mass. The authors describe a 42-year-old woman who was admitted to the department of obstetrics and gynecology to receive treatment for presumed advanced-stage ovarian cancer. She subsequently received a diagnosis of primary pseudomyxoma peritonei metastatic to the ovaries, mimicking a primary ovarian cancer by osteopathic structural examination findings, serum tumor markers, surgical exploration, and histopathologic confirmation.

Intact Cornual Ectopic Pregnancy and Dermoid Cyst With Intraoperative Rupture.

Of ectopic pregnancies encountered in clinical practice, more than 95% are located within the fallopian tube, and 2% to 4% are cornual. A cornual ectopic pregnancy is a serious clinical condition and poses diagnostic and therapeutic challenges. Thus, understanding the clinical course and treatment options is essential. The authors describe the case of a 29-year-old woman who presented to the Department of Obstetrics and Gynecology. The patient was suspected of having a cornual pregnancy, and a dermoid cyst had been detected during routine ultrasonography. In the absence of maternal symptoms, the clinical scenario is potentially dangerous and must be treated promptly and efficiently to decrease morbidity and mortality.

Minimally Invasive Valve Surgery and Single Vessel Coronary Artery Bypass via Limited Anterior Right Thoracotomy.

BACKGROUND: Coronary artery bypass grafting with aortic valve replacement (AVR) or mitral valve replacement (MVR) is traditionally performed via sternotomy. Minimally invasive coronary surgery (MICS) and minimally invasive valve surgery have been successfully performed independently. Patients with critical right coronary artery (RCA) stenosis not amenable to percutaneous intervention are candidates for valve replacement and single vessel coronary artery bypass. We present our series of six patients who underwent a concomitant valve and single vessel intervention via right thoracotomy. METHODS: Between January 2011 and June 2013, six patients underwent right thoracotomy with valve replacement and single vessel bypass. Four aortic and two mitral valves were replaced and all received single vessel RCA bypass using reversed saphenous vein graft. Thoracotomy was via right anterior approach for AVR and right lateral for MVR. The patients were assessed postoperatively for overall outcomes. RESULTS: The average age was 74 years (range 69-81); two patients were elective (AVR-1; MVR-1) and four were urgent (AVR-3; MVR-1). For MICS AVR and MICS MVR, the average cardiopulmonary bypass time was 171 ± 30 and 169 ± 7 minutes and the average aortic cross-clamp time was 122 ± 36 and 112 ± 2 minutes, respectively. Three patients were discharged home, one patient to a nursing home, and two to rehab. No patients required conversion to sternotomy; one patient developed atrial fibrillation, and one sepsis. CONCLUSION: Concomitant valve replacement and single bypass grafting via right anterior mini-thoracotomy is a viable option for select patients, particularly in non-stentable RCA stenosis. In the appropriate patient population, combined coronary artery bypass grafting and valve surgery can be safely performed via right thoracotomy.
