Syphilitic proctitis presenting as locally advanced rectal cancer: A case report.

INTRODUCTION: Syphilis is an infectious disease that is uncommonly encountered in surgical patients. We present a case of severe syphilitic proctitis leading to large bowel obstruction with imaging findings mimicking locally advanced rectal cancer. PRESENTATION OF CASE: A 38-year-old man who had sex with men presented to the emergency department with a 2 week history of obstipation. The patient's medical history was significant for poorly controlled HIV. Imaging demonstrated a large mass in the rectum and the patient was admitted to the colorectal surgery service for management of presumed rectal cancer. Sigmoidoscopy demonstrated a rectal stricture and biopsies showed severe proctitis without evidence for malignancy. Given the patient's history and discordant clinical findings an infectious workup was pursued. The patient tested positive for syphilis and was diagnosed with syphilitic proctitis. He underwent treatment with penicillin and although he experienced a Jarisch-Herxheimer reaction, his bowel obstruction completely resolved. Final pathology on the rectal biopsies demonstrated positive Warthin-Starry and spirochete immunohistochemical stain. DISCUSSION: This case illustrates key aspects in the care of a patient with syphilitic proctitis mimicking an obstructing rectal cancer, including the need for high clinical suspicion, thorough evaluation including sexual and sexually transmitted disease history, multidisciplinary communication, and management of the Jarisch-Herxheimer reaction. CONCLUSION: Severe proctitis leading to large bowel obstruction is a possible presentation of syphilis, and a high degree of clinical suspicion is necessary to be able to accurately identify the cause. An increased awareness of the Jarisch-Herxheimer reaction following treatment of syphilis is critical to provide appropriate care in this patient population.

Mycotic right subclavian artery aneurysm: a rare and challenging pathology.

Mycotic subclavian artery aneurysms are rare but challenging pathology. We report a 67-year-old woman who presented with recurrent bacteremia secondary to chronic clavicular osteomyelitis. Imaging demonstrated a right subclavian artery aneurysm near the innominate artery bifurcation and in close proximity to the infected clavicle. Owing to the anatomic location, among other factors, she underwent open repair using a rifampin-soaked Dacron conduit. Analysis of the aneurysm wall identified bacteria consistent with intraoperative bone and blood cultures. Contributions from multiple surgical and medical specialties provided a favorable, long-term outcome for the patient.

Effect of antihypertensive medications on thrombolysis therapy and outcomes in acute ischemic stroke patients.

There are concerns that specific risk factors may alter the benefits of thrombolysis in stroke patients with controlled contraindications including hypertension. The objective of this study was to evaluate the association between clinical risk factors and outcomes in ischemic stroke patients that received thrombolysis therapy pretreated with antihypertensive medications. Using data obtained from a stroke registry, a non-randomized retrospective data analysis was conducted on patients with the primary diagnosis of acute ischemic stroke with hypertension pretreated with antihypertensive medications. The association between clinical risk factors and functional ambulatory outcome was determined using logistic regression while odd ratios (OR) were used to predict the odds of achieving improved ambulatory outcome in thrombolysis treatment status. Improved or poor functional ambulatory outcome was considered as the end point in our analysis. A total of 4665 acute ischemic stroke patients were identified, of whom 1446 (31.0%) were eligible for thrombolysis, while 3219 were not, and 595 received rtPA, of whom 288 were on antihypertensive medications, while 233 were not. In the rtPA group with antihypertensive (anti-HTN) medication, only NIHSS score (OR = 1.094, 95% CI, 1.094-1.000, P = 0.005) was associated with improved functional outcome while patients with congestive heart failure (OR = 0.385, 95% CI, 0.385-0.159, P = 0.035) and patients with a history of previous TIA (OR = 0.302, 95% CI, 0.302-0.113, P = 0.017) were more likely to be associated with poor functional outcomes. Congestive heart failure and TIA are independent predictors of functional outcomes in stroke patients pretreated with antihypertensive medications prior to thrombolysis therapy.

Prevalence of and factors associated with utilization of herbal medicines among outpatients in primary health centers in Cambodia.

BACKGROUND: Traditional, complementary and alternative medicine (TCAM) is seen as a way to provide healthcare in both developed and developing countries across the world. In Cambodia, there is a long tradition of using TCAM. However, scant studies have been conducted on the extent of Cambodian TCAM use and how it interacts with allopathic health care to date. In this study, we examined the prevalence of and factors associated with utilization of herbal medicines among patients with chronic diseases in primary health care settings in Cambodia. METHODS: A cross-sectional survey was conducted in 2015 with outpatients receiving treatment and care for chronic diseases in two urban and two rural primary health centers purposively selected from Phnom Penh, Kampong Cham and Siem Reap. Every eligible patient was randomly selected at the health centers using a systematic sampling procedure. I-CAM-Q was used to measure TCAM use. A multivariate logistic regression model was constructed to identify factors associated with herbal medicine use. RESULTS: In total, 1602 patients were included in this study, of whom 77.7% were female, and 51.2% were recruited from urban primary health centers with a mean age of 46.5 years (SD = 15.2). Of total, 27.0% reported at least one consultation with a TCAM provider in the past 12 months. The most common modality of TCAM used was herbal medicine (89%). Herbs were obtained at drug or folk stores (36.9%), from herbalists directly (28.5%) or from their own gardens (18.6%). Of herb users, 55.2% reported that herbs were somewhat helpful. After adjustment, herb users were significantly more likely to be female (AOR = 1.42, 95% CI = 1.12-2.67), have completed less schooling (AOR = 0.66, 95% CI = 0.45-0.96), were unemployed or homemakers (AOR = 0.23, 95% CI = 0.13-0.52) and have a gastrointestinal illness (AOR = 0.49, 95% CI = 0.39-0.62). CONCLUSIONS: Herbal medicines are broadly used among chronic disease patients in Cambodia. Understanding TCAM use in the general population will support health care practitioners and policy makers to make informed decisions about the use of TCAM. Integration of TCAM into the primary health system should be further explored.

Evaluating the Effectiveness of One-on-One Conversations to Increase Colorectal Cancer Screening in a Community-Based Clinical Setting.

CONTEXT: The American Cancer Society's 80% by 2018 initiative aims to increase at-home colorectal cancer (CRC) screening. OBJECTIVE: To assess the effectiveness of one-on-one conversations with patients about CRC screening on compliance with at-home fecal immunochemical tests (FITs). SETTING: Federally funded health care center serving a largely minority, urban, underserved population in Vallejo, California. METHODS: Patients aged 50 to 75 years were divided into 3 main intervention arms: (1) patients who received a one-on-one in-person consultation to discuss the need for CRC screening and the screening process, as well as a FIT; (2) patients who received a telephone call to discuss the need for CRC screening and the screening process before receiving a FIT in the mail; and (3) patients who were mailed a FIT with a letter explaining the importance of completing the FIT and instructions. The FITs were tracked to see if they were returned to the laboratory for processing, and the rates of return were compared in bivariate analyses using t and χ2 tests and in adjusted analyses using logistic regression with bootstrapping. RESULTS: A total of 3415 patients were included in the study. One-on-one conversations either in person (OR, 24.63; 95% CI, 19.28-31.46) or via telephone (OR, 14.74; 95% CI, 10.96-19.82) were more effective at getting patients to complete the at-home CRC screening than not having one-on-one conversations before receiving the FIT. CONCLUSION: Patients may be more likely to complete at-home FITs to screen for CRC if they are first able to discuss the need for screening and the screening process with a health care professional.

Utilization of traditional, complementary and alternative medicine and mental health among patients with chronic diseases in primary health care settings in Cambodia.

BACKGROUND: Coping with chronic illnesses often involves major lifestyle changes that may lead to poor mental health. Furthermore, in order to treat the chronic conditions, many sufferers in Asia turn to traditional, complementary and alternative medicines (TCAM). This study explores prevalence of TCAM use and factors associated with anxiety and depressive symptoms among patients with chronic diseases in Cambodia. METHODS: In 2015, this cross-sectional study was conducted with outpatients receiving treatment and care for chronic diseases in two urban and two rural primary health centers. Every eligible patient was randomly selected at the health centers using a systematic sampling procedure. Symptoms of anxiety and depression were assessed by using the Hospital Anxiety and Depression Scale (HADS). Multivariate logistic regression models were constructed to explore factors associated with anxiety and depressive symptoms. RESULTS: The study participants included 1528 patients, of whom 77.2% were female, with a mean age of 46.5 years (SD = 15.3). After adjustment, patients with depressive symptoms remained significantly more likely to be in the age groups between 41 and 60 years old and to be married, separated/divorced or widowed compared to those without depressive symptoms. Regarding the use of TCAM, patients with depressive symptoms remained significantly more likely to report using an herbalist, practicing visualization and praying for own health, but less likely to report using vitamins or supplements in the past 12 months. For quality of life, patients with depressive symptoms remained significantly less likely to agree that they had enough energy for their everyday life and had enough money to meet their daily needs. Similar risk factors were also found to be significantly associated with anxiety symptoms. CONCLUSIONS: Cambodian patients with chronic diseases who experienced symptoms of anxiety or depression were more likely to report reduced quality of life, greater chronic disease-related stigma and more TCAM use. Given the potential interaction of TCAM, mental health and other chronic conditions, a history of TCAM use and mental health should be elicited in clinical practices in primary health care settings, particularly in developing countries.

Reduced Postvasectomy Semen Analysis Testing With the Implementation of Special Clearance Parameters.

OBJECTIVE: To determine the applicability of postvasectomy special clearance parameters (<100,000 nonmotile sperm/mL on semen analysis) suggested by the American Urological Association and to define the associated cost savings with avoidance of further testing. MATERIALS AND METHODS: We retrospectively reviewed the cohort of men undergoing vasectomy from December 2009 to August 2012 at a single institution. Patient demographics and postvasectomy semen analysis (PVSA) results were collected for clearance parameter comparisons. RESULTS: During the study period, 230 patients underwent vasectomy with a mean ± SD age of 36.4 ± 6.5 years. Among the cohort, 83.5% were married and 95.2% had one or more children. The initial PVSA was completed by 111 (48.3%) patients at a mean of 17.8 weeks (range 4-45) following vasectomy. Sperm was identified on initial PVSA in 40 patients (36.0%); 1 patient was found to have motile sperm. Of 39 patients, 38 (97.4%) with nonmotile sperm on PVSA could be cleared to cease other contraceptives based on the most recent clearance guidelines. For those completing an initial PVSA, postvasectomy clearance increased from 64.0% to 98.2% representing a potential cost savings of $2356 in repeat semen testing. CONCLUSION: Postvasectomy contraceptive clearance can be greatly increased when rare nonmotile sperm parameters are included although postvasectomy semen testing compliance remains poor.

Association of tumor size, location, R.E.N.A.L., PADUA and centrality index score with perioperative outcomes and postoperative renal function.

PURPOSE: Multiple scoring systems have been proposed to standardize the description of anatomical features of renal tumors. However, it remains unclear which of these systems, if any, is most useful, or whether any performs better than simply reporting tumor size or location in patients undergoing partial nephrectomy. To clarify these issues we evaluated the association of tumor size, location, R.E.N.A.L. (Radius/Exophytic/Nearness to collecting system/Anterior/Location), PADUA (Preoperative Aspects and Dimensions Used for an Anatomical classification) and centrality index scores with perioperative outcomes. MATERIALS AND METHODS: Patients undergoing partial nephrectomy with available preoperative imaging were identified from 2005 to 2011. R.E.N.A.L., PADUA and centrality index scores were assigned according to the described protocols for those systems. Associations between each variable and ischemia time, estimated blood loss, total operative time and change in estimated glomerular filtration rate were examined. RESULTS: A total of 162 patients were identified with a median tumor size of 3.1 cm (IQR 2.2 to 4.6). Median estimated blood loss, ischemia time and total operative time were 200 ml (IQR 100 to 300), 24 minutes (IQR 20 to 30) and 211 minutes (IQR 179 to 249), respectively. Each scoring system was found to have a statistically significant (p <0.001) correlation with ischemia time, with the centrality index system showing the strongest correlation. Furthermore, each of the scoring systems showed a stronger correlation with ischemia time than tumor size or tumor location. CONCLUSIONS: Each scoring system outperformed tumor size and location, and may be useful when describing the surgical complexity of renal tumors treated with partial nephrectomy.

"Now the African reigns supreme": the rise of African boxing on the Witwatersrand, 1924-1959.

This essay explores the growth of boxing among the African populations on the Witwatersrand region of South Africa between 1924 and 1959. It details how the sport's jump in popularity with Africans paralleled migration to Johannesburg. Africans increasingly saw boxing as an activity and skill conducive with survival in this new environment, and thus the sport grew in popularity, stature, and skill-level amongst this emergent urban population. The essay further explores the various ways that the sport was disseminated and popularized during the era, thus detailing how the sport reached both the African masses and petit-bourgeois educated elite. As their presence in Johannesburg became more and more permanent, boxing came to encompass various meanings and ideals, such as notions of discipline, independence and civility, to these urban populations.
