The feasibility of tricuspid annular plane systolic excursion performed by transesophageal echocardiography throughout heart surgery and its interchangeability with transthoracic echocardiography.

Tricuspid annular plane systolic excursion (TAPSE) is a robust measure of RV function, but the performance of transesophageal echocardiography (TEE) measured TAPSE during surgery is not well established. We aim to evaluate feasibility of various TEE views before, during and after surgery. Furthermore, we compare performance of individual TEE measurements depending on view and method (AMM- and M-mode as well as 2D) as well as TAPSE measured using TEE with transthoracic echocardiography (TTE) TAPSE. The study was conducted from January 2015 through September 2016. In 47 patients with normal left ventricular ejection fraction, TEE was prospectively performed during coronary artery bypass grafting surgery. TAPSE and tricuspid annulus tissue Doppler imaging (TDI) were recorded in five different views at pre-specified time points during surgery. Data were analyzed for availability (obtainable/readable images) and reliability (intra-/inter-observer bias and precision). Finally, TEE TAPSE was compared to TTE TAPSE immediately before and after surgery. TAPSE and TDI with TEE was achievable in > 90% of patients in the transgastric view during surgery. The AM- and M-mode had the best reliability and the best correlation with TAPSE measured with TTE. The deep transgastric view was achievable in less than 50% after sternotomy, and TAPSE measured from 2D had a poorer performance compared to the AM- and M-mode. TDI demonstrated a high reliability throughout surgery. RV function can be evaluated by TAPSE and TDI using TEE during surgery. TEE values from the transgastric view demonstrated high performance throughout surgery and a good agreement with TTE TAPSE measurements.

Emergency coronary artery bypass surgery after failed percutaneous transluminal coronary angioplasty.

Coronary complications caused by percutaneous transluminal coronary angioplasty (PTCA) may necessitate emergency coronary artery bypass grafting (CABG). In 1994-1998, 132 patients (1.5% of the patients registered in the Danish PTCA registry) underwent CABG within 24 h because of angioplasty complications. We reviewed the files of 86 patients who had emergency operations within 6 h and found that 35% suffered from 1-vessel disease. Fifty-eight percent were taken directly to the operating room from the cardiovascular laboratory, and 13% were given preoperative cardiovascular resuscitation. The vessels most frequently injured were the right coronary artery and the left anterior descending branch (LAD). The patients received a mean of 2.4 coronary bypasses each. Forty-three percent of the patients with lesions of the left main coronary artery and/or the LAD received a vein graft to the LAD. A perioperative Q-wave myocardial infarction developed in 51% of the patients. The in-hospital mortality rate was 12%. These results are inferior to those obtained after elective surgery. Local cardiothoracic backup is vital when PTCA is performed in an unselected patient group.

Suicidal ideation and suicide attempts among adult Danes.

This study describes the prevalence of suicidal ideation and attempted suicide in a representative survey among adults in Denmark and gives the proportion of people reporting a suicide attempt that results in contact with the health care system. The data for the 1994 Danish national health interview survey were collected by personal interview and a self-administered questionnaire. A subsample of 1362 individuals participated in the part of the survey that addressed suicidal behaviour (64% of the random sample). The results show that 6.9% reported having had suicidal thoughts within the past year. Averaging across all age groups the overall prevalence of people reporting ever having made a suicide attempt was 3.4% and the one-year prevalence was 0.5%. Suicidal ideation was more prevalent among young people than among older people, whereas ever-attempted suicide showed no age gradient. Both suicidal ideation and ever-attempted suicide were more prevalent among economically inactive people (e.g. unemployed) and among unmarried or divorced people. We estimate that 50-60% of suicide attempts reported in a representative, national survey become known to the healthcare system.

Rash related to use of scented products. A questionnaire study in the Danish population. Is the problem increasing?

Fragrances are used in many types of cosmetic and household products, which are an important part of everyday life in modern society. The aim of the current investigation was to describe the frequency of self-reported rash due to scented products in a random sample of the adult Danish population. Further, it was determined whether risk of self-reported 1st-time rash from scented products had increased during the past 15 years compared to the preceding period. The sample consisted of 1537 persons, 801 female and 736 male, above the age of 15 years. The participants were interviewed person-to-person to obtain a general health profile, and in this connection, questions were asked concerning rash related to the use of scented products. 28.6% (440/1537) had on some occasion experienced rash from scented products, 10.6% had experienced rash within the year prior to interview. A multivariate analysis showed that women had a significantly increased risk of reporting rash from scented products compared to men (odds ratio: 1.56, p<0.0001). Furthermore, it was shown that individuals below the age of 40 years had a significantly increased risk of reporting rash from scented products compared to older age groups. The risk of reporting 1st-time rash occurring after 1978 was significantly increased (odds ratio: 2.34, p<0.0001), as compared to the preceding period. This may be taken as indicative of an increasing problem with scented products, involving potentially severe public health implications.

[Self-reported health and morbidity among adult Danes 1987-1994]. / Selvrapporteret sundhed og sygelighed blandt voksne danskere 1987-1994.

Developments in morbidity among adult Danes were studied by means of representative national health interview surveys conducted in 1987, 1991, and 1994. Each health interview survey was based on personal interviews with a sample of 6000 Danes. Response rates were about 80%. From 1987 to 1994 prevalence of long-standing illness increased from 33 to 38%, prevalence of health-related restrictions of daily activities increased from 11 to 14%, while prevalence of perceived poor health decreased slightly and prevalence of not feeling well enough to do what you want to do decreased from 22 to 19%. In 1994 16% reported reduced psychological well-being within a four week period, and 23% had due to emotional problems accomplished less than they desired at work or in other daily activities. The prevalence of self-reported morbidity and ill-health increased with increasing age, and for most of the indicators prevalence was higher among women than among men.

Identification of risk products for fragrance contact allergy: a case-referent study based on patients' histories.

BACKGROUND: Fragrances are the first or second most common cause of contact allergy in dermatitis patients. OBJECTIVE: The aim of this study was to identify risk products for fragrance contact allergy. METHODS: The design was a case-control study with a case group of 78 fragrance-mix-positive eczema patients and two control groups, one consisting of 1,279 subjects selected as a random sample of the general population and the other consisting of 806 fragrance-mix-negative eczema patients. The identification of risk products was based on the patients' histories of rash to scented products. Analysis of the associations between first-time rash caused by different specified product categories and fragrance mix sensitivity was performed using logistic regression. RESULTS: It was found that first-time rash caused by deodorant sprays and/or perfumes were related to fragrance contact allergy in a comparison with both control groups. The risk (odds ratio) of being diagnosed as fragrance allergic was 2.3 to 2.9 greater in cases of a history of first-time rash to deodorant sprays and 3.3 to 3.4 greater in cases of a history of rash to perfumes than if no such history were present. First-time rash to cleansing agents, deodorant sticks, or hand lotions was also statistically significant but only in comparison with one of the control groups. CONCLUSION: Safety evaluation of fragrance materials used in perfumes and deodorant sprays should be performed with special attention.

Influence of complete revascularization on long-term survival after coronary artery bypass surgery.

To evaluate the influence of complete coronary revascularization after coronary artery bypass grafting (CABG) on long-term survival, we reviewed the records, including reports of coronary angiography, of 198 patients (25 women). Coronary artery bypass grafting was performed in the period 1973-1982, when the patients' mean age was 52.5 years. No significant (p < 0.05) difference in survival in the first 15 postoperative years was found between the patients judged to have complete revascularization at coronary angiography 6 months after CABG and the general Danish population. Complete revascularization by extensive grafting should improve survival of patients treated for angina. If the revascularization remains complete at coronary angiography assessment 6 months postoperatively, the 15-year survival rate can be expected to equal that in the general population.

Fibromyalgia in the adult Danish population: I. A prevalence study.

Epidemiologic studies of fibromyalgia have so far been based on rheumatologic and general practice settings, which are poor proxies for the underlying population. The study is based on a national health interview survey carried out by the Danish Institute for Clinical Epidemiology in 1990/91 on approx. 6000 randomly selected Danish citizens. For this study 1219 subjects from the eastern part of Denmark aged 18 to 79 years were asked about widespread muscle pain. One-hundred-and-twenty-three persons fulfilled the screening criteria. Clinical examination could be performed on 65 persons (53%). Eight subjects, all female, met the 1990 American College of Rheumatism criteria for fibromyalgia. Dropouts were regarded as not having fibromyalgia. The prevalence of fibromyalgia in the Danish population between 18 and 79 years of age was found to be a minimum estimate of 0.66% (95% confidence limits 0.28%-1.29%).

Fibromyalgia in the adult Danish population: II. A study of clinical features.

Clinical characteristics of fibromyalgia have so far been based mainly on patients identified in rheumatologic settings. This paper offers the clinical findings in fibromyalgia based on a national health interview survey, in which 123 persons fulfilled preset criteria for widespread pain. Clinical examination could be performed on 65 subjects (53%) and included physical examination, tender point palpation by two blinded trained physicians, blood sample analysis, measurement of dynamic muscular strength and a detailed self-administered questionnaire. Significantly more subjective swelling, fatigue, headache, difficulty in stair-climbing, and poorer self-evaluated health with more tender points was found. Contrary to that which was expected, fibromyalgia subjects did not suffer from sleep disturbances, irritable bowels or morning stiffness. Our findings indicate that clinical characteristics of fibromyalgia in the general population may differ from those found in rheumatological settings.

Transport conditions and number of biopsies necessary for culture of Helicobacter pylori.

Stuart's transport medium with a charcoal impregnated swab was tested for transport of biopsies from the gastric antrum for culture of Helicobacter pylori. Biopsies were cultured under microaerophilic conditions either within 2 h or after a delay of 24 h at 4 degrees C. In 65 patients referred for gastroscopy two biopsies were taken. Helicobacter pylori was found in 39 patients. The rate of survival of Helicobacter pylori was found to be as high in Stuart's transport medium after 24 h at 4 degrees C as in the paired biopsy which was cultured immediately after transportation in normal saline. In five (13%) of 39 patients positive for Helicobacter pylori, the organism was cultured from only one of the biopsies. It is therefore recommended that two biopsies be taken for culture.

[Helicobacter pylori]. / Helicobacter pylori.

Ever since 1983 when Marshall & Warren succeeded in cultivating Helicobacter pylori (HP) (previously known as Campylobacter pylori) a high incidence thereof has been demonstrated in patients with ulcers and non-ulcerous dyspepsia. Helicobacter pylori is easily diagnosed via microscopy, cultivation and serological tests. The bacterium may be treated with antibiotics or the ulcer drug bismuth subcitrate (De-Nol). The pathogenetic role of HP is not clear. Some studies have shown a lower recurrence rate of duodenal ulcers after treatment addressed to Helicobacter pylori with the ulcer drug De-Nol, which suggests that HP plays a role in the onset of recurrence in cases of ulcus duodeni.

Wound infection after cesarean section.

A prospective multicenter study of 1,032 cesarean sections was performed to identify risk factors for postoperative wound infection. The overall rate of wound infection was 6.6% (3.8% in elective cases and 7.5% following nonelective operations), with considerable interhospital variation. Obesity was recognized as a patient-related risk factor, while risk factors inherent to the obstetric situation were duration of ruptured membranes prior to operation, fetal and labor monitoring by intrauterine devices, and omission of the use of plastic draping and redisinfection of the skin before closure. Logistic regression analysis was used to estimate the influence of these factors on the probability of wound infection. Certain risk factors associated with and over-represented in nonelective operations would explain the increased infection rates in these, and the observed interhospital variations did not differ from the expected rates when the distribution of other risk factors was considered.

Prenatal obstruction of the ileum diagnosed by ultrasound.

A case of low atresia of the ileum, diagnosed prenatally by real-time ultrasound scanning, is presented. The ultrasound examination showed progressive distension of intestinal loops, with strong peristaltic movements. The stomach was also distended, presenting as a large cystic area in the upper left abdomen. Real-time ultrasound technique is most advantageous in the diagnosis of fetal ileus. Prenatal diagnosis of fetal intestinal obstruction is of great importance, making early and safe treatment of the newborn possible.
