Epididymal leiomyoadenomatoid tumor: A case report of a rare benign paratesticular mass.

Primary tumors of the epididymis are rare and commonly benign in nature. Leiomyoadenomatoid tumors are a rare subvariant of adenomatoid tumors that combines features of leiomyomas. Tumor histology is notable for tubular spaces lined by mesothelial cells with a proliferative spindle cell component. To the best of our knowledge, few cases have been reported in the literature. We report a case of leiomyoadenomatoid tumor in a 58-year-old male.

Combined intra- and extra-peritoneal bladder perforation following rectal impalement injury.

A 62-year-old male presented with abdominal pain and hematuria following impalement of the rectum with a wooden foreign object. CT imaging showed air and fluid in the peritoneum prompting the patient to undergo abdominal exploration. An anterior rectal perforation was discovered along with dual bladder lacerations of the posterior wall and dome. The patient underwent a diverting colostomy and primary bladder repair. Post-operative course was uncomplicated and bladder repair was followed via cystograms with catheter removal 2 months post-operatively. Four months after the injury the patient underwent colostomy closure and remains with normal bladder and bowel function at 21-month follow-up.

Metastatic Colorectal Adenocarcinoma in a Bifid Ureter.

Background: Secondary malignancies of the ureter are uncommon. We report the diagnosis and management of metastatic colon cancer to the bifurcation of a bifid ureter. Case Presentation: A 59-year-old man presented with diffuse metastasis with right hydronephrosis in both renal moieties of a partially duplicated system and an enhancing lesion within the proximal common ureter. Ureteral biopsy was positive for colorectal adenocarcinoma. The patient was subsequently started on palliative chemoradiation. Conclusion: The ureter is a rare location for hematogenous/lymphatic metastases. When a ureteral mass is present on imaging, ureteroscopy should be performed to characterize the extent of tumor and to rule out secondary malignancy.

An in-depth look into the association between morningness-eveningness and well-being: evidence for mediating and moderating effects of personality.

Morningness-eveningness and standard personality traits are associated with well-being but few studies have directly compared the two types of construct as correlates of life satisfaction. Influences on well-being common to both chronotype and personality may include shared biological bases for depression and sleep disturbance, tendencies toward social jetlag, and emotion-regulation mechanisms. The current study tested mediation and moderation hypotheses in a sample of 379 Polish adults. The first hypothesis was that conscientiousness and emotional stability traits would mediate the relationship between morningness and life satisfaction. Consistent with previous results, morningness, the two personality traits, and satisfaction tended to be mutually positively correlated. A multiple mediation analysis showed that both traits partially mediated the morningness-satisfaction association. Data are compatible with morningness influencing personality development adaptively, although other causal hypotheses could be advanced. The second hypothesis was that extraversion would moderate the association between chronotype and satisfaction. This hypothesis was supported, with extraverted evening types showing disproportionately high life satisfaction, whereas introverted evening types showed the lowest levels of satisfaction. Level of extraversion may influence whether or not evening types choose to engage in adaptive social activities that boost well-being during the evening hours. Results demonstrate the importance of investigating both chronotype and personality in studies of well-being.

Prostate Cancer Screening Trends After United States Preventative Services Task Force Guidelines in an Underserved Population.

Purpose: Prostate cancer screening is a controversial topic. We examined trends in Prostate Specific Antigen (PSA) testing in an underserved population before and after the United States Preventative Services Task Force (USPSTF) recommendation against screening. Methods: Data were collected on all PSA and cholesterol screening tests from 2008 to 2014. We examined the trend of these tests and prostate biopsies while comparing this data to lipid panel data to adjust for changes in patient population. Results: A decrease in PSA screening was observed from 2010 through 2014, with the greatest decline in 2012. The age group most affected was patients aged 55-69 years. The amount of prostate biopsies during this period decreased as well. Conclusions: Decreased rates of PSA screening were observed in our urban hospital population that preceded the publication of the USPSTF guidelines. The incidence of prostate biopsies decreased in this timeframe. It now remains to be demonstrated whether decreased PSA screening rates impact the diagnosis of and ultimately the survival from prostate cancer.

Sepsis after elective ureteroscopy.

INTRODUCTION: We sought to determine our rate of postoperative sepsis after ureteroscopy as well as identifying associative factors, common antibiotic practices along with culture data. MATERIALS AND METHODS: Records of all patients who underwent elective ureteroscopy from 2010 to 2015 at an urban tertiary care facility were retrospectively reviewed. Factors thought to be associated with infection were collected, along with comorbidities depicted as Charlson Age-Adjusted Comorbidity Index (CAACI) and American Society of Anesthesia (ASA) score. Each patient's course was reviewed to determine if they were treated for postoperative sepsis as defined by standardized criteria. RESULTS: A total of 345 patients underwent elective ureteroscopy with 15 (4.3%) being treated for sepsis postoperatively. This resulted in an additional 5.33 ± 3.84 days of hospitalization per patient. The sepsis group grew three gram positive organisms and five multi-drug resistant (MDR) gram negatives while 7/15 (46.7%) had negative cultures. The most common preoperative antibiotics used in the sepsis group were cefazolin (60.0%), gentamicin (48.5%) and ciprofloxacin (20.0%). Univariate analysis showed prior endoscopic procedures, recent treatment for urinary tract infections (UTI), multiple comorbidities and longer operative times associated with sepsis. However, significant variables after multivariate analysis were treatment for UTI within the last month, (OR) 7.19 (2.25-22.99), p = 0.001. CONCLUSIONS: Patients with multiple comorbidities, prior endoscopic procedures, longer operative times and especially those recently treated for a urinary infection should be carefully monitored after ureteroscopy for signs of sepsis. Perioperative antibiotics in these patients should be selected to cover both MDR organisms and gram positives.

Factors Influencing Readmission after Elective Ureteroscopy.

PURPOSE: Ureteroscopy is increasingly used to manage nephrolithiasis, upper urinary tract urothelial carcinoma and other urological conditions. In this study we determine the rate of readmission and emergency department visits after ureteroscopy in an underserved population, as well as factors associated with these unplanned visits. MATERIALS AND METHODS: A retrospective chart review from 2010 to 2014 of all elective ureteroscopies was conducted at a single tertiary hospital serving an underserved population in a major metropolis. Demographic, operative and discharge characteristics were collected and analyzed. RESULTS: A total of 276 ureteroscopies were performed with 15.6% presenting to the emergency department within 30 days. Overall 5.8% were readmitted. Readmitted patients were more likely to have hypertension (OR 3.64, p=0.02), asthma or chronic obstructive pulmonary disease (OR 5.54, p=0.001), 2 or more comorbidities (OR 3.65, p=0.12), or a complication associated with ureteroscopy (OR 7.27, p=0.007). The patients who sought care in the emergency department after ureteroscopy were less likely to have had a ureteral stent in place before ureteroscopy (OR 0.35, p=0.017) or an endoscopic urological procedure within the last 30 days (OR 0.35, p=0.045). About two-thirds of patients who presented to the emergency department complained of pain alone, while the most common complaints for readmitted patients were fever and pain (43.8%). CONCLUSIONS: The majority of emergency department visits after ureteroscopy were due to pain. These patients were less likely to have a preoperative ureteral stent placed or a history of recent urological procedures. Readmission rates were associated with overall comorbidities and complications.

Mental workload and stress perceived by novice operators in the laparoscopic and robotic minimally invasive surgical interfaces.

BACKGROUND AND PURPOSE: High levels of mental workload and stress are experienced by surgeons in the laparoscopic environment. The da Vinci(®) surgical robot was developed to provide surgeons a more user-friendly interface while maintaining the patient benefits associated with laparoscopy. This study examined whether the da Vinci robot reduces mental workload and stress in novice medical students. A detailed understanding of trainees' mental workload and mental stress experiences can aid in the development of training programs that are aimed at facilitating the acquisition of laparoscopic and robotic surgery skills. MATERIALS AND METHODS: Fifteen novice first-year medical students performed a standard peg-transfer task at a laparoscopic simulator and the da Vinci Surgical System. Mental workload and stress were assessed with the Multiple Resources Questionnaire (MRQ) and the Dundee Stress State Questionnaire (DSSQ), respectively. RESULTS: Students' mental workload profiles were identical with the two surgical systems and replicated previous MRQ results reported with the laparoscopic system showing high levels of workload. Students experienced a better stress profile with the robotic system, however, when compared wih the laparoscopic system. CONCLUSION: Our study shows that novice medical students perceive less stress when working with the robotic surgical interface than with the laparoscopic surgery interface. The MRQ and the DSSQ are valuable tools for identifying mental workload and mental stress in the laparoscopic and robotic surgery environments. This information may be useful for facilitating the acquisition of laparoscopic and robotic surgery skills.

Physician work intensity among medical specialties: emerging evidence on its magnitude and composition.

BACKGROUND: Similarities and differences in physician work intensity among specialties are poorly understood but have implications for quality of care, patient safety, practice organization and management, and payment. OBJECTIVE: To determine the magnitude and important dimensions of physician work intensity for 4 specialties. RESEARCH DESIGN: Cross-sectional assessment of work intensity associated with actual patient care in the examination room or operating room. SUBJECTS: A convenience sample of 45 family physicians, 20 general internists, 22 neurologists, and 21 surgeons, located in Kansas, Kentucky, Maryland, Ohio, and Virginia. MEASURES: Work intensity measures included the National Aeronautics and Space Administration-Task Load Index (NASA-TLX), Subjective Work Assessment Technique (SWAT), and Multiple Resource Questionnaire. Stress was measured by the Dundee Stress State Questionnaire. RESULTS: Physicians reported similar magnitude of work intensity on the NASA-TLX and Multiple Resource Questionnaire. On the SWAT, general internists reported work intensity similar to surgeons but significantly lower than family physicians and neurologists (P=0.035). Surgeons reported significantly higher levels of task engagement on the stress measure than the other specialties (P=0.019), significantly higher intensity on physical demand (P < 0.001), and significantly lower intensity on the performance dimensions of the NASA-TLX than the other specialties (P=0.003). Surgeons reported the lowest intensity for temporal demand of all specialties, being significantly lower than either family physicians or neurologists (P=0.014). Family physicians reported the highest intensity on the time dimension of the SWAT, being significantly higher than either general internists or surgeons (P=0.008). CONCLUSIONS: Level of physician work intensity seems to be similar among specialties.

Clinical work intensity among physician specialties: how might we assess it? What do we find?

BACKGROUND: The level of work intensity associated with patient encounters has implications for quality of care, patient safety, practice management, and reimbursement. The utility of available instruments for clinical work intensity assessment is unknown. OBJECTIVE: We assessed, in the clinical setting, the performance of existing measures of work intensity that are valid for nonclinical contexts. RESEARCH DESIGN: A cross-sectional, multimeasure design involving work intensity assessments for the last patient encounter and for an entire half-day clinic session. SUBJECTS: A convenience sample of 14 providers from the following 4 specialties: family medicine, general internal medicine, neurology, and surgery. MEASURES: Perceived clinical work intensity was measured by the following 3 instruments: National Aeronautic and Space Administration-Task Load Index, Subjective Workload Assessment Technique, and Multiple Resources Questionnaire; stress was measured by the Dundee Stress State Questionnaire. Convergent validity was assessed by correlation among the instruments. RESULTS: For the last patient encounter, there was a moderate to high correlation between the work intensity instruments' scores (Pearson's r ranged from 0.41 to 0.73) and low to moderate correlation with the distress subscale of the Dundee Stress State Questionnaire (Pearson's r ranged from -0.11 to 0.46), reflecting their stress dimension. Provider personality was associated with reported levels of work intensity and stress. Similar results were obtained when the entire clinic session was the unit of reference. CONCLUSION: Existing measures of work intensity and stress appear to be valid for use in the clinical setting to generate evidence on perceived intensity and stress experienced by providers in the performance of medical services.

Perceptual distortions produce multidimensional stress profiles in novice users of an endoscopic surgery simulator.

OBJECTIVES: We determine the impact of perceptual-motor distortions on multidimensional stress dynamics in novice users of an endoscopic/laparoscopic surgery simulator during performance of a peg-transfer task. BACKGROUND: Surgeons find the endoscopic/laparoscopic surgery procedure to be more mentally stressful than open surgery. This investigation was designed to identify specific stress dimensions associated with these procedures and to determine the contributions to that stress made by loss of depth information resulting from image-guided views of the surgical field and by disruption of eye-hand mapping. Because stress reactions might depend upon familiarity with these procedures, the study focused upon novice participants. METHOD: An endoscopic box-simulator featured in surgical training was used in conjunction with the Dundee Stress State Questionnaire, a well-validated multidimensional stress state instrument. A control group (no perceptual distortions) viewed the simulated "surgical field" directly. Two other groups viewed the surgical field through TV images in which spatial rotation of the images was absent or in which the images were rotated 90 degrees from the actual line of sight. RESULTS: Performance efficiency in the simulator varied inversely with the degree of perceptual-motor distortion. Reactions reflecting increased task coping were observed in all groups. These were accompanied in the image groups by negative reactions involving decreases in hedonic tone and control and confidence and an increase in tense arousal. CONCLUSIONS: Perceptual-motor distortions are sources of complex task-induced stress profiles in novices using an endoscopic surgery simulator. APPLICATION: Procedures to reduce stress in endoscopic/laparoscopic surgery trainees may benefit from knowledge regarding specific stress dimensions involved.
