Patient-centric comparative analysis of experiences in open upright and conventional closed MRI scanners.

INTRODUCTION: MRI often induces anxiety, leading to incomplete scans and claustrophobia-related distress. Open MRI systems aim to enhance patient comfort. This study examines how prior MRI experiences impact subsequent encounters in an open upright MRI scanner. METHODS: In this cross-sectional study, 118 adult patients completed a self-administered questionnaire from August 2022 to October 2023. It covered previous MRI experiences, including questions about claustrophobia, premature scan terminations, sedative medication usage, general MRI experiences, and interactions with radiology technologists. RESULTS: Patients in open upright MRI reported less claustrophobia compared to closed MRI systems (18.4% vs. 58.3%), fewer premature scan terminations (5.3% vs. 31.0%), and less sedative use (5.3% vs. 46.9%). Moderate positive correlations were found between past and current claustrophobic events and premature scan terminations. Effective communication with radiology technologists was essential for patient comfort and reduced claustrophobia. Scan duration and noise triggered discomfort in 26.1% and 21.6% of study participants respectively. Persons without prior MRI experience were more satisfied with the examination and expressed no clear preference for future MRI settings, contrasting those with previous exposure favoring the open MRI setup. CONCLUSION: The study emphasizes the benefits of open upright MRI for high-risk claustrophobic patients. It identifies the lasting impact of negative MRI experience on future examinations and highlights the crucial role of radiology technologists. IMPLICATIONS FOR PRACTICE: Integrating open MRI scanners in medical facilities and prioritizing effective communication with radiology technologists enhances patient comfort. Positive experiences with open MRI may improve patient compliance and offer greater flexibility for future examinations.

Expense for Clinical Documentation of Inpatients: Extent and Hierarchal Differences for the Example of a Gynaecological Department in Switzerland.

Introduction: The majority of physicians consider administrative tasks to be a burden. The present questionnaire is intended to clarify the expense of time for documentation tasks in the treatment of inpatients in a gynaecological department of a Swiss hospital and to what extent differences occur between senior physicians and junior physicians. Materials and Methods: For three weeks physicians in the gynaecological department of a central Swiss hospital documented minute for minute predefined tasks during their duty periods. A questionnaire in tabular form served as survey instrument for this working time analysis. The minute for minute details for the individual participants were summed for each clinical task listed in the questionnaire in order to subsequently calculate the amounts of time spent for the respective task categories and to subject them to a subgroup analysis. Results: The participation rate of the physicians amounted to 87 %. 287 questionnaires were included in the evaluation. According to the responses, 25 % of the clinical working time for inpatients was used for documentation of clinical tasks. The subgroup analysis revealed a higher proportion for assistant physicians (30 %) than for senior physicians (18 %). Discussion: The present working time analysis reveals an unfavourable ratio between surgical and administrative tasks between junior and senior physicians. In addition there is a danger that the true burden for junior physicians is underestimated by their superiors due to hierarchal differences.

Pregnancy After a Laparoscopic Sacrohysteropexy: a Case Report.

Pelvic Organ Prolapse (POP) is a rare condition during pregnancy. If all conservative treatments fail, the surgical approach has proven to be in non-pregnant women a very good option due to high efficacy and a very low morbidity and mortality rate. We are reporting on the clinical results of a 33-year-old pregnant woman with a past history of laparoscopic sacrohysteropexy who delivered by caesarean section due to a foetal breech presentation. There are only a handful of cases reporting the outcome "pregnancy" after a laparoscopic sacrohysteropexy. Nevertheless, this appears to be a useful intervention for women with a POP unresponsive to conservative treatment and open family planning. Further studies with long-term follow-ups are required to confirm this.

Spontaneous rupture of an adrenal artery in pregnancy: a case report.

A spontaneous rupture of an adrenal artery is a rare cause of abdominal pain in pregnancy. We present a case of a pregnant woman who needed to be operated on because of a rupture of the right adrenal artery associated with a fetal bradycardia. An immediate caesarean section was performed. The intra-abdominal palpation identified an extensive retroperitoneal mass near the right kidney and a postoperative computer tomography confirmed an active bleeding near the kidney. For this reason our interventional radiology team, using a right femoral artery approach, performed a flush aortogram and identified the source of bleeding in the right adrenal artery. After two attempts, a coiling of the artery stopped the haemorrhage. The pathogenesis of arterial haemorrhage is still poorly understood although a possible cause could be the excess of hormones during pregnancy, which can lead to a significant arterial wall degeneration. In case of a retroperitoneal bleeding and if the patient is still haemodynamically stable, a transcatheter embolization using microcoils must be considered. This technique is nowadays safe and effective and can be performed within a short time with a lower risk of complications.

Chylomicronemia Syndrome in Pregnancy: a Case Report of an Acute Necrotizing Pancreatitis.

Introduction: Chylomicronemia syndrome (CS) is a rare disorder characterized by a high level of triglycerides in plasma. We present a case of a pregnant woman with a severe acute pancreatitis (AP) affected by a CS. Case: A 38-year-old gravida 2, para 0 with an uneventful course of pregnancy was referred with an AP at 37 0/7 weeks of gestation. This diagnosis was made from a nearby hospital where the chemical analysis showed elevated pancreatic enzymes with significant hypertriglyceridemia. Because of a pathological fetal heart tracing a caesarean delivery was performed. The APGAR score of the female newborn was 5/8/8 at 1, 5 and 10 minutes, respectively. The pH from the umbilical cord were 7.26 (artery) and 7.59 (vein). Once transferred to our intensive care unit a computer tomography scan confirmed an onset of a necrotizing AP. A conservative treatment was tried without success. For this reason a surgical debridement of the infected and necrosic parts was performed. After a long hospitalisation the patient could be dismissed after 2.5 months in good general condition. Discussion: Lipid profile changes in normal pregnancy are characterized by an elevation of total plasma cholesterol and triglyceride levels. This is normally caused by an increased liver synthesis of triglycerides in response to elevated estrogen levels. When a CS is diagnosed the main goal is to maintain fasting triglyceride levels at less than 500 mg/dL to reduce the risk for AP. Conclusion: Practitioners have an important role in evaluating chylomicronemic patients and implementing therapeutic lifestyle and pharmaceutic interventions aimed to reduce the risk for AP.

Population-based study of wake-up strokes.

OBJECTIVE: Previous studies have estimated that wake-up strokes comprise 8%to 28% of all ischemic strokes, but these studies were either small or not population-based. We sought to establish the proportion and event rate of wake-up strokes in a large population-based study and to compare patients who awoke with stroke symptoms with those who were awake at time of onset. METHODS: First-time and recurrent ischemic strokes among residents of the Greater Cincinnati/Northern Kentucky region (population 1.3 million) in 2005 were identified using International Classification of Diseases-9 codes 430-436 and verified via study physician review. Ischemic strokes in patients aged 18 years and older presenting to an emergency department were included. Baseline characteristics were ascertained, along with discharge modified Rankin Scale scores and 90-day mortality. RESULTS: We identified 1,854 ischemic strokes presenting to an emergency department, of which 273 (14.3%) were wake-up strokes. There were no differences between wake-up strokes and all other strokes with regard to clinical features or outcomes except for minor differences in age and baseline retrospective NIH Stroke Scale score. The adjusted wake-up stroke event rate was 26.0/100,000. Of the wake-up strokes, at least 98 (35.9%) would have been eligible for thrombolysis if arrival time were not a factor. CONCLUSIONS: Within our population, approximately 14% of ischemic strokes presenting to an emergency department were wake-up strokes. Wake-up strokes cannot be distinguished from other strokes by clinical features or outcome. We estimate that approximately 58,000 patients with wake-up strokes presented to an emergency department in the United States in 2005.

Increased suicide risk among workers following toxic metal exposure at the Paducah gaseous diffusion plant from 1952 to 2003: a cohort study.

BACKGROUND: Suicide is a problem worldwide and occupation is an important risk factor. In the last decade, 55 200 deaths in the US were attributed to occupational risk factors. OBJECTIVE: To determine if toxic metal exposure was associated with suicide risk among Paducah gaseous diffusion plant (PGDP) workers. METHODS: We assembled a cohort of 6820 nuclear industry workers employed from 1952 to 2003. A job-specific exposure matrix (JEM) was used to determine metal exposure likelihood. Uranium exposure was also assessed by urinalysis. All suicide/self-injury International Classification for Disease (ICD) codes were used to identify suicides. Standardized mortality ratios (SMR), odds ratios (OR), and hazard ratios (HR) were used to estimate suicide risk. RESULTS: PGDP suicide victims typically were younger white men. Within exposure likelihood categories, several suicide SMRs were typically elevated for several metals. Only beryllium exposure likelihood was associated with an increased HR. Uranium urine concentration was associated with an elevated suicide risk after stratification by urinalysis frequency. CONCLUSION: Suicide risk is associated with uranium exposure.

[Caregiver burden with dementia patients. A validation study of the German language version of the Zarit Burden Interview]. / Die subjektive Belastung pflegender Ehepartner von Demenzkranken. Hinweise zur Validität der deutschen Version des Zarit Burden Interviews.

Despite the large number of studies dealing with dementia caregivers in Europe, a valid German version of the most widely used measurement of caregiver burden, the Zarit Burden Interview, has not been published. The purpose of this study was to evaluate the psychometric properties of the German Zarit Burden Interview (G-ZBI). A sample of community-dwelling older couples (n=37) with the husband suffering from dementia and the wife being the primary caregiver participated in this study. The G-ZBI and related constructs were assessed in order to test for reliability and construct validity. The G-ZBI revealed psychometric properties comparable with those of the original instrument and empirically validated translations. Results indicate high internal consistency (Cronbach's alpha=0.91) and good validity due to strong correlations with caregiver life satisfaction and depression, as well as patients' dependency, neuropsychiatric symptoms, and dementia severity. The psychometric qualities of the G-ZBI indicate that it is both a reliable and valid instrument to assess caregiver burden and to detect highly stressed individuals.

[Tobacco consumption of adults diagnosed with ADHD]. / Tabakkonsum bei Erwachsenen mit ADHS.

OBJECTIVE: Research in the USA has demonstrated numerous associations between adult attention-deficit/hyperactivity disorder (ADHD) and smoking behaviour; however, no specific work on this topic has been done in Switzerland. The aim of the study was to gain knowledge about the association between ADHD and tobacco consumption in a Swiss sample of adult ADHD patients. METHODS: The study subjects were recruited from patients with a DSM-IV diagnosis of ADHD consecutively presenting to the ADHD consultation service at the Centre for Addiction Disorders, an outpatient facility of the Zurich University Hospital, between September 2000 and January 2006. Complete data could be obtained from 100 of 134 patients presenting to the service. RESULTS: The number of current smokers in the ADHD sample was significantly elevated compared to the Swiss general population (55 vs 31%). Additionally, daily smokers in the ADHD sample smoked significantly more cigarettes per day, reported higher levels of nicotine dependence and started to smoke regularly at a significantly younger age. The motivation to quit smoking was high. CONCLUSIONS: The results of this Swiss study are consistent with previous research in the USA. The fact that many adults with ADHD are motivated to quit smoking and that they actually make use of support in quitting is crucial for secondary tobacco prevention.

Stage I carcinoma of the Bartholin's gland managed with the detection of inguinal and pelvic sentinel lymph node.

BACKGROUND: Primary carcinoma of the Bartholin's gland is rare, consequently standard management is not clear. Although the sentinel concept has gained popularity for other malignancies of the female reproductive tract, the literature lacks reports of this approach for carcinomas of the Bartholin's gland. CASE: We present a patient with stage I adenocarcinoma of the Bartholin's gland. She was managed with wide excision and inguinal and laparoscopic pelvic sentinel lymphadenectomy followed by complete pelvic lymphadenectomy. We discuss the rationale for the sentinel concept. CONCLUSION: As for other gynaecological malignancies the sentinel lymphadenectomy seems to be an appropriate and feasible surgical approach for early stage carcinomas of the Bartholin's gland.

Optical properties of the breast during spontaneous and birth control pill-mediated menstrual cycles.

Mastodynia is correlated with the menstrual cycle. Using frequency-domain near-infrared spectroscopy (FD-NIRS), we investigated changes in breast perfusion in women who were or were not using hormonal contraception. Healthy volunteers, on or not on hormonal contraception, were examined. Optical properties were measured in all quadrants of both breasts, and physiological parameters were calculated. Measurements were repeated every other day during one complete menstrual cycle. Measurements were comparable in all quadrants. Data remained unchanged during the entire cycle in patients using hormonal contraception. However, a biphasic variation of deoxyhemoglobin, oxyhemoglobin, total hemoglobin (tHb), and water content (H(2)O) was observed in women not using contraception. tHb and H(2)O distinctly increased during the ovulation period and remained elevated throughout the luteal phase. It was concluded that FD-NIRS allows accurate measurement of optical properties of human breasts. As opposed to the menstrual cycles of persons using oral contraception, spontaneous menstrual cycles exhibit biphasic variations of tissue perfusion parameters. These findings are important for the investigation of mastodynia.

Age at intracranial aneurysm rupture among generations: Familial Intracranial Aneurysm Study.

BACKGROUND: Previous studies have reported intracranial aneurysm (IA) occurring at young ages in subsequent generations. These studies did not correct for duration of follow-up. Second-generation members who would have their ruptured IA late in life may not be detected due to shorter follow-up time than the first generation. We examined families in which ruptured IA occurred in two consecutive generations for the hypothesis that the second generation (F1) was more likely to have a rupture at a younger age than the older generation (F0). METHODS: The Familial Intracranial Aneurysm (FIA) Study is a multicenter, international study recruiting families of ruptured and unruptured IA. All available family members are interviewed. Cox proportional hazards regression models and Kaplan-Meier curves were used to examine differences by generation. RESULTS: Although we found that the F1 generation was more likely to have an aneurysm rupture at a younger age than the F0 generation, we found that this was largely because of a lack of follow-up time in the F1 generation. The F1 generation had 50% the rupture rate of the prior generation. When analyzed by Kaplan-Meier curves, we found a tendency to have a slightly later rupture rate in the F1 generation once time to follow-up was included in the analysis model. CONCLUSIONS: Families of ruptured intracranial aneurysm (IA) do not appear to demonstrate "anticipation." Our finding suggests that genetic epidemiology of ruptured IA should examine all types of variations such as single base-pair changes, deletions, insertions, and other variations that do not demonstrate anticipation.

Successful granulocyte-colony stimulating factor treatment of Crohn's disease is associated with the appearance of circulating interleukin-10-producing T cells and increased lamina propria plasmacytoid dendritic cells.

Granulocyte-colony stimulating factor (G-CSF) has proved to be a successful therapy for some patients with Crohn's disease. Given the known ability of G-CSF to exert anti-T helper 1 effects and to induce interleukin (IL)-10-secreting regulatory T cells, we studied whether clinical benefit from G-CSF therapy in active Crohn's disease was associated with decreased inflammatory cytokine production and/or increased regulatory responses. Crohn's patients were treated with G-CSF (5 microg/kg/day subcutaneously) for 4 weeks and changes in cell phenotype, cytokine production and dendritic cell subsets were measured in the peripheral blood and colonic mucosal biopsies using flow cytometry, enzyme-linked immunosorbent assay and immunocytochemistry. Crohn's patients who achieved a clinical response or remission based on the decrease in the Crohn's disease activity index differed from non-responding patients in several important ways: at the end of treatment, responding patients had significantly more CD4(+) memory T cells producing IL-10 in the peripheral blood; they also had a greatly enhanced CD123(+) plasmacytoid dendritic cell infiltration of the lamina propria. Interferon-gamma production capacity was not changed significantly except in non-responders, where it increased. These data show that clinical benefit from G-CSF treatment in Crohn's disease is accompanied by significant induction of IL-10 secreting T cells as well as increases in plasmacytoid dendritic cells in the lamina propria of the inflamed gut mucosa.

Does antenatal pelvic dilation predict renal scarring?

Moderate antenatal renal pelvic dilation (5-15 mm) may suggest vesicoureteric reflux, but it is not known to predict renal scarring. Dimercaptosuccinic acid scans on such children aged over 4 years showed a scarring rate (0/133 boys, 1/56 girls) similar to our local population. Investigation and treatment of moderate dilation may not be required.

[Erectile dysfunction in men in their second half of life]. / Erektile Dysfunktion bei Männern in der zweiten Lebenshälfte.

BACKGROUND: Studies to date on the prevalence of erectile dysfunction (ED) report varying results. The present study investigates the frequency and degree of ED, its determining factors as well as the help-seeking behavior of the patients. PATIENTS AND METHODS: A random sample of 628 Swiss men (mean age: 61.5 years) were examined by questionnaire regarding their sexual functioning, comorbidity, and help-seeking behavior. RESULTS: Of the respondents, 9.6% reported complete, 18.0% moderate, and 41.4% minimal ED. All grades of the disorder increased with age and correlated with somatic and psychiatric comorbidity as well as with drug intake. Only 3.2% reported having used drugs for improvement of erectile functioning. CONCLUSION: Only a small number of men suffering from ED seek the help of a doctor. Considering the efficacy of PDE5 inhibitors, objective information and competent medical counseling of ED patients are indicated.
