Expectations related to home-based telemonitoring of high-risk pregnancies: A qualitative study addressing healthcare providers' and users' views in Norway.

INTRODUCTION: A pregnancy can be evaluated as high-risk for the woman and/or the fetus based on medical history and on previous or ongoing pregnancy characteristics. Monitoring high-risk pregnancies is crucial for early detection of alarming features, enabling timely intervention to ensure optimal maternal and fetal health outcomes. Home-based telemonitoring (HBTM) is a marginally exploited opportunity in antenatal care. The aim of this study was to illuminate healthcare providers' and users' expectations and views about HBTM of maternal and fetal health in high-risk pregnancies before implementation. MATERIAL AND METHODS: To address diverse perspectives regarding HBTM of high-risk pregnancies, four different groups of experienced healthcare providers or users were interviewed (n = 21). Focus group interviews were conducted separately with midwives, obstetricians, and women who had previously experienced stillbirth. Six individual interviews were conducted with hospitalized women with ongoing high-risk pregnancies, representing potential candidates for HBTM. None of the participants had any previous experience with HBTM of pregnancies. The study is embedded in a social constructivist research paradigm. Interviews were analyzed using a thematic approach. RESULTS: The participants acknowledged the benefits and potentials of more active roles for both care recipients and providers in HBTM. Concerns were clearly addressed and articulated in the following themes: eligibility and ability of women, availability of midwives and obstetricians, empowerment and patient safety, and shared responsibility. All groups problematized issues crucial to maintaining a sense of safety for care recipients, and healthcare providers also addressed issues related to maintaining a sense of safety also for the care providers. Conditions for HBTM were understood in terms of optimal personalized training, individual assessment of eligibility, and empowerment of an active patient role. These conditions were linked to the importance of competent and experienced midwives and obstetricians operating the monitoring, as well as the availability and continuity of care provision. Maintenance of safety in HBTM in high-risk pregnancies was crucial, particularly so in situations involving emerging acute health issues. CONCLUSIONS: HBTM requires new, proactive roles among midwives, obstetricians, and monitored women, introducing a fine-tuned balance between personalized and standardized care to provide safe, optimal monitoring of high-risk pregnancies.

Humoral immunity to SARS-CoV-2 mRNA vaccination in multiple sclerosis: the relevance of time since last rituximab infusion and first experience from sporadic revaccinations.

INTRODUCTION: The effect of disease-modifying therapies (DMT) on vaccine responses is largely unknown. Understanding the development of protective immunity is of paramount importance to fight the COVID-19 pandemic. OBJECTIVE: To characterise humoral immunity after mRNA-COVID-19 vaccination of people with multiple sclerosis (pwMS). METHODS: All pwMS in Norway fully vaccinated against SARS-CoV-2 were invited to a national screening study. Humoral immunity was assessed by measuring anti-SARS-CoV-2 SPIKE RBD IgG response 3-12 weeks after full vaccination, and compared with healthy subjects. RESULTS: 528 pwMS and 627 healthy subjects were included. Reduced humoral immunity (anti-SARS-CoV-2 IgG <70 arbitrary units) was present in 82% and 80% of all pwMS treated with fingolimod and rituximab, respectively, while patients treated with other DMT showed similar rates as healthy subjects and untreated pwMS. We found a significant correlation between time since the last rituximab dose and the development of humoral immunity. Revaccination in two seronegative patients induced a weak antibody response. CONCLUSIONS: Patients treated with fingolimod or rituximab should be informed about the risk of reduced humoral immunity and vaccinations should be timed carefully in rituximab patients. Our results identify the need for studies regarding the durability of vaccine responses, the role of cellular immunity and revaccinations.

Effects of external cephalic version for breech presentation at or near term in high-resource settings: A systematic review of randomized and non-randomized studies.

INTRODUCTION: External cephalic version (ECV) for breech presentation involves manual manipulation of the fetus from breech to cephalic presentation at or near term, in an attempt to avoid breech birth. This systematic review summarizes the literature on the effects of ECV at or near term on pregnancy outcomes in high-resource settings. METHODS: The MEDLINE, Embase, CINAHL, Cochrane Library, MIDIRS, and SweMED+ databases were searched for relevant articles published through April 2019, with no limitation on publication date. Clinical trials comparing the effects of ECV at ≥36 weeks, with or without tocolysis, with that of no ECV, conducted in northern, western, and central Europe, the USA, Canada, Australia, and New Zealand were eligible for inclusion. RESULTS: Nine articles reporting on 184704 breech pregnancies were included. Pooled data showed that ECV attempts reduced the failure to achieve vaginal cephalic birth (risk ratio, RR=0.56; 95% CI: 0.45-0.71), caesarean section performance (RR=0.57; 95% CI: 0.50-0.64), and non-cephalic presentation at birth (RR=0.45; 95% CI: 0.29-0.68) compared with no ECV. ECV attempts also increased the incidence of Apgar score <7 at 5 minutes (RR=1.29; 95% CI: 1.10-1.52). CONCLUSIONS: Women for whom ECV is attempted at or near term are at reduced risk of caesarean section, non-cephalic presentation at term, and failure to achieve vaginal cephalic birth. Compared with no ECV, attempted ECV was also associated with a slightly increased risk of a low Apgar score at 5 minutes. The evidence is limited by the scarcity of high-quality research and the presence of risks of bias.

One-to-one care routines and compliance with the national professional recommendation on continuous intrapartum support in Norway: A national survey.

INTRODUCTION: In 2010, the Norwegian Directorate of Health introduced the guideline 'Safe maternity services - quality standards for maternal care'. These standards include adequate staffing with health care personnel for birth units to ensure responsible monitoring and treatment. Birth units are to follow the professional recommendation that every woman has a midwife present during established labor. This study presents data from birth units on compliance with the national recommendation for one-to-one care during labor. METHODS: A web-based questionnaire was emailed to chief midwives of all birth units in Norway (n=48) in May 2018. The questionnaire contained a total of nine multiple-choice, scaled-response-format, and free-text questions. RESULTS: The questionnaire response rate was 100%. All birth units reported that they offered women one-to-one care during labor to a large extent. Sixty-five per cent of the birth units had procedures to ensure that midwives were present during established labor. Deviations from the recommendation were recorded in one-fourth of birth units. Thirty-eight per cent of respondents reported that staff training had been provided; 56% of birth units stated that the recommendation led to an increased presence of midwives during labor. Financial constraints (35%) and difficulty of compliance (27%) were cited as obstacles to meeting the recommendation for one-to-one care during labor. CONCLUSIONS: The majority of birth units reported that they follow the recommendation for one-to-one care during established labor, but compliance with this recommendation in practice remains unclear. Areas of improvement relate to routines describing the presence of midwives during labor, registration of deviations, and staff training in one-to-one care.

National survey of routines for intrapartum fetal monitoring in Norway.

INTRODUCTION: This study describes clinical routines for intrapartum fetal monitoring in Norway and compliance with national clinical recommendations. MATERIAL AND METHODS: A national survey of all (n = 48) birth units in Norway, using a self-reporting questionnaire about fetal monitoring methods and devices available in the birth units, admission cardiotocography (CTG) use, intrapartum fetal monitoring methods for women with and without risk factors, the availability of fetal scalp blood sampling facilities, and umbilical cord blood sampling routines. RESULTS: All birth units responded. They all had access to Pinard stethoscopes, hand-held Doppler devices, and CTG. Half of the units used ST waveform analysis (STAN) as an adjunct to CTG. Furthermore, 23 of 48 units analyzed fetal blood samples and 43 of 48 umbilical cord blood gas samples. In 11 units, admission CTG was routinely offered to all women. No units used continuous CTG during labor in low-risk women. However, three units routinely used intermittent CTG during the first stage of labor. Three units used CTG without having access to fetal blood samples or STAN. CONCLUSIONS: Our findings indicate some deviations from clinical recommendations in the use of intrapartum fetal monitoring in Norway. Three units used intermittent CTG for women without risk factors. Almost one in four units routinely used admission CTG, despite national clinical recommendations. The lack of access to fetal blood samples or STAN in units using CTG is of concern.

X-chromosomal maternal and fetal SNPs and the risk of spontaneous preterm delivery in a Danish/Norwegian genome-wide association study.

BACKGROUND: Recent epidemiological studies suggest that the maternal genome is an important contributor to spontaneous preterm delivery (PTD). There is also a significant excess of males among preterm born infants, which may imply an X-linked mode of inheritance for a subset of cases. To explore this, we examined the effect of maternal and fetal X-chromosomal single nucleotide polymorphisms (SNPs) on the risk of PTD in two independent genome-wide association studies and one replication study. METHODS: Participants were recruited from the Danish National Birth Cohort and the Norwegian Mother and Child cohort studies. Data from these two populations were first analyzed independently, and then combined in a meta-analysis. Overall, we evaluated 12,211 SNPs in 1,535 case-mother dyads and 1,487 control-mother dyads. Analyses were done using a hybrid design that combines case-mother dyads and control-mother dyads, as implemented in the Haplin statistical software package. A sex-stratified analysis was performed for the fetal SNPs. In the replication study, 10 maternal and 16 fetal SNPs were analyzed using case-parent triads from independent studies of PTD in the United States, Argentina and Denmark. RESULTS: In the meta-analysis, the G allele at the maternal SNP rs2747022 in the FERM domain containing 7 gene (FRMD7) increased the risk of spontaneous PTD by 1.2 (95% confidence interval (CI): 1.1, 1.4). Although an association with this SNP was confirmed in the replication study, it was no longer statistically significant after a Bonferroni correction for multiple testing. CONCLUSION: We did not find strong evidence in our data to implicate X-chromosomal SNPs in the etiology of spontaneous PTD. Although non-significant after correction for multiple testing, the mother's G allele at rs2747022 in FRMD7 increased the risk of spontaneous PTD across all populations in this study, thus warranting further investigation in other populations.

Catalytic asymmetric Mannich reactions of glycine derivatives with imines. A new approach to optically active alpha,beta-diamino acid derivatives.

Imines of glycine alkyl esters react with imines in a diastereo- and highly enantioselective Mannich reaction in the presence of chiral copper(I) complexes as the catalyst to give optically active alpha,beta-diamino acid derivatives. A series of imines of glycine esters derived from glycine and aromatic carbonyl compounds has been screened as substrates for the Mannich reaction with different imines in the presence of various combinations of metal salts and chiral ligands. The benzophenone imine of glycine esters was found to react with N-protected imines in a diastereoselective fashion giving functionalized alpha,beta-diamino acid esters with excellent enantioselectivities. The most effective chiral catalysts are chiral copper(I) complexes having phosphino-oxazoline (P,N)-ligands, and among these ligands, those derived from (1R,2S)-dihydroxy-1,2,3,4-tetrahydronaphthalene gave the best results. The scope of this new catalytic asymmetric reaction of the benzophenone imine glycine esters is demonstrated for the reaction with different N-protected-C-aryl and C-alkyl imines giving the Mannich adducts with excellent optical purity. Furthermore, the synthetic aspects of the reaction are presented by converting the Mannich adducts into alpha,beta-diamino acid derivatives. The relative and absolute configuration of the Mannich adduct have been determined and based on the stereochemical outcome of the reaction a tetrahedral chiral-copper(I)-imino glycine alkyl ester intermediate is proposed. In this intermediate the Re-face of the benzophenone imine glycine ester is shielded by the chiral ligand leaving the Si-face available for approach of the Si-face of the imine. A series of semiempirical calculations has been performed to support the structure of the tetrahedral chiral-copper(I) complex and to account for the influence of the substituents in the chiral phosphino-oxazoline ligands.

Intestinal permeability of x-ray constrast media iodixanol and iohexol during bacterial overgrowth of small intestines in rats.

To investigate the recovery of iodinated water-soluble contrast medium from small bowel with small morphological alterations, iohexol or iodixanol was instilled through an orogastric tube in rats 14 days after surgery that established a self-filling blind loop in the jejunum. This rat model induced small bowel bacterial overgrowth with only minor abnormalities observed on histology and scanning electron microscopy. Animals with end-to-end anastomosis of the jejunum or unoperated rats served as controls. Compared with unoperated animals, urinary recovery of iohexol and iodixanol was significantly higher in both groups that underwent surgery. Moreover, the contrast medium recovery was numerically higher in the self-filling blind loop group given iodixanol than in the end-to-end anastomosis group, although not statistically significant, P = 0.09. Our results indicate that iohexol and iodixanol may detect small barrier impairments in the intestines. Iodixanol, the largest of the two, may seem to differentiate better between normal and minimally impaired intestinal barrier.

"Probability of successful defibrillation" as a monitor during CPR in out-of-hospital cardiac arrested patients.

The frequency spectrum of the ECG in ventricular fibrillation (VF) correlates with myocardial perfusion and might predict defibrillation success defined as return of spontaneous circulation (ROSC). The predictive power increases when more spectral variables are combined, but the complex information can be difficult to handle during the intensity of CPR. We therefore developed a method for expressing this multidimensional information in a single reproducible variable reflecting the probability of defibrillation success. This is based on the highest performing predictor for ROSC after 883 shocks given to 156 patients with VF. This was a combination of two decorrelated spectral features based on a principal component analysis of an original feature set with information on centroid frequency, peak power frequency, spectral flatness and energy. The function "Probability of defibrillation success" (P(ROSC)(v)) was developed by a 2-dimensional histogram technique. P(ROSC)(v) discriminated between shocks followed by ROSC and No-ROSC (P<0.0001). The present methodology indicates a possible way to develop a CPR monitor.

[Crohn disease of the oral cavity, illustrated by some cases]. / Crohns sykdom i munnhulen, belyst med noen kasuistikker.

BACKGROUND: We have several times experienced that Crohn's disease has not been diagnosed until several years after the start of oral symptoms. This article presents some patients with oral manifestations of Crohn's disease, as a contribution to more awareness of this possibility. MATERIAL AND METHODS: Clinical and histological data from four patients are presented. RESULTS: All patients had granulomatous inflammation of the oral mucosa. In three patients, the disease started in the mouth. The diagnosis of intestinal Crohn's disease was made from some months up to seven years later. In one patient, no granuloma was found in the intestinal tract, but the patient had intestinal symptoms. Two patients experienced disappointments in their contacts with the local health care system, with considerable delay in diagnosis. INTERPRETATION: We interpret these cases as evidence that a greater awareness of the possibility of Crohn's disease in the oral cavity may lead to a quicker diagnosis, earlier correct treatment, and less patient worry caused by uncertainty.

Detection of chromogranin A in human gastric adenocarcinomas using a sensitive immunohistochemical technique.

Neuroendocrine cells are often disclosed in human gastric adenocarcinomas and may be recognised by their immunoreactivity towards chromogranin A. However, in dedifferentiated neuroendocrine tumour cells, the chromogranin A content may be reduced making it difficult to detect with conventional immunohistochemical methods. We therefore used a sensitive signal amplification technique in order to evaluate chromogranin A immunoreactivity and thus neuroendocrine differentiation in 40 gastric adenocarcinomas. Neuroendocrine cells were visualised by means of a monoclonal chromogranin A antibody and the avidin-biotin peroxidase complex technique, without and with addition of tyramide signal amplification. Double immunohistochemistry towards chromogranin A and Ki-67 were used to disclose proliferation in the neoplastic cells. A marked increase in the number of carcinomas containing chromogranin A-immunoreactive neoplastic cells was noted when applying the tyramide signal amplification technique. In addition, the number of immunoreactive cells within each tumour increased, and in some cases almost all the neoplastic cells became immunoreactive. Chromogranin A-immunoreactive tumour cells showing signs of proliferation were found in the majority of these carcinomas. In conclusion, we have disclosed widespread immunoreactivity towards chromogranin A in a proportion of gastric adenocarcinomas when enhancing the signal with tyramide signal amplification. Neuroendocrine differentiation is thus a common finding in gastric carcinomas when using sensitive methods.

CPR artifact removal from human ECG using optimal multichannel filtering.

The purpose of this study was to assess whether the artifacts presented by precordial compressions during cardiopulmonary resuscitation could be removed from the human electrocardiogram (ECG) using a filtering approach. This would allow analysis and defibrillator charging during ongoing precordial compressions yielding a very important clinical improvement to the treatment of cardiac arrest patients. In this investigation we started with noise-free human ECGs with ventricular fibrillation (VF) and ventricular tachycardia (VT) records. To simulate a realistic resuscitation situation, we added a weighted artifact signal to the human ECG, where the weight factor was chosen to provide the desired signal-to-noise ratio (SNR) level. As artifact signals we used ECGs recorded from animals in asystole during precordial compressions at rates 60, 90, and 120 compressions/min. The compression depth and the thorax impedance was also recorded. In a real-life situation such reference signals are available and, using an adaptive multichannel Wiener filter, we construct an estimate of the artifact signal, which subsequently can be subtracted from the noisy human ECG signal. The success of the proposed method is demonstrated through graphic examples, SNR, and rhythm classification evaluations.

Predicting outcome of defibrillation by spectral characterization and nonparametric classification of ventricular fibrillation in patients with out-of-hospital cardiac arrest.

BACKGROUND: In 156 patients with out-of-hospital cardiac arrest of cardiac cause, we analyzed the ability of 4 spectral features of ventricular fibrillation before a total of 868 shocks to discriminate or not between segments that correspond to return of spontaneous circulation (ROSC). METHODS AND RESULTS: Centroid frequency, peak power frequency, spectral flatness, and energy were studied. A second decorrelated feature set was generated with the coefficients of the principal component analysis transformation of the original feature set. Each feature set was split into training and testing sets for improved reliability in the evaluation of nonparametric classifiers for each possible feature combination. The combination of centroid frequency and peak power frequency achieved a mean+/-SD sensitivity of 92+/-2% and specificity of 27+/-2% in testing. The highest performing classifier corresponded to the combination of the 2 dominant decorrelated spectral features with sensitivity and specificity equal to 92+/-2% and 42+/-1% in testing or a positive predictive value of 0.15 and a negative predictive value of 0.98. Using the highest performing classifier, 328 of 781 shocks not leading to ROSC would have been avoided, whereas 7 of 87 shocks leading to ROSC would not have been administered. CONCLUSIONS: The ECG contained information predictive of shock therapy. This could reduce the delivery of unsuccessful shocks and thereby the duration of unnecessary "hands-off" intervals during cardiopulmonary resuscitation. The low specificity and positive predictive value indicate that other features should be added to improve performance.

Oxyntic lesions may be provoked in the rat both by the process of acid secretion and also by gastric acidity.

BACKGROUND: Gastric ischaemia appears to be a common pathogenetic factor for stress ulcers. These ulcers occur predominantly in the oxyntic mucosa, suggesting that the acid secretory process or its stimulation is involved in the pathogenesis. METHODS: We examined separately the role of the acid secretory process and gastric luminal acidity in the pathogenesis of gastric lesions using the isolated vascularly perfused acid-secreting rat stomach. RESULTS: Pentagastrin-stimulated acid secretion induced submucosal bleeding in the oxyntic mucosa whether accompanied by perfusion of the gastric lumen with saline or a phosphate buffer at pH 7.0. On the other hand, acidity, whether endogenous or introduced by luminal perfusion, induced erosions in both the oxyntic and antral mucosa. CONCLUSION: It is concluded that the acid secretory process itself contributes to the particular vulnerability of the oxyntic mucosa to ischaemia. Histamine released upon stimulation of gastric acid secretion or shortage of energy due to the requirements for acid secretion may both contribute to this vulnerability. Furthermore, these findings suggest that inhibition of gastric acid secretion should be superior to antacids in preventing stress ulcers.

Substance P may attenuate gastric hyperemia by a mast cell-dependent mechanism in the damaged gastric mucosa.

Calcitonin gene-related peptide (CGRP) released from sensory neurons, which are closely apposed to mast cells and blood vessels, mediates gastric hyperemia in response to acid challenge of the damaged mucosa. Substance P (SP) is coreleased with CGRP from sensory neurons, but the role of this peptide in gastric blood flow regulation is largely unknown. Chambered rat stomachs were exposed to 1.5 M NaCl and acidic saline after treatment with SP, aprotinin (serine protease inhibitor), and the mast cell stabilizers ketotifen and sodium cromoglycate (SCG). Gastric hyperemia (measured with a laser Doppler flow velocimeter) after hypertonic injury and acid challenge was nearly abolished by SP. Aprotinin infused together with SP and pretreatment with ketotifen and SCG before SP restored the gastric hyperemia. Ketotifen and SCG inhibited mast cell degranulation in SP-treated rats. Preservation of gastric hyperemia was correlated with improved mucosal repair. These data suggest that impaired hyperemia by SP during acid challenge of the gastric mucosa may be mediated by a mast cell-dependent mechanism involving the release of proteases from mast cells.

Helicobacter pylori infection and risk of cardia cancer and non-cardia gastric cancer. A nested case-control study.

BACKGROUND: Helicobacter pylori infection is an established risk factor for gastric adenocarcinoma. Potential confounding by socioeconomic factors has not been adequately assessed, and the magnitude of the relative risk in relation to gastric subsites, morphologic subtypes, sex, age, and follow-up time need further study. METHODS: We conducted a serologic case-control study nested within the Norwegian JANUS cohort. Between 1972 and 1986 serum was collected from 101,601 subjects who were followed up with regard to cancer development through 1992. RESULTS: Among 208 gastric adenocarcinoma cases, we found a strong positive association between H. pylori infection and non-cardia gastric cancer (odds ratio (OR), 5.15; 95% confidence interval (CI), 2.83-9.37), and a statistically significant negative association with cardia cancer (OR, 0.40; 95% CI, 0.20-0.77). Adjustment for socioeconomic factors and smoking did not materially alter the effect estimates. The association between the infection and non-cardia cancer was stronger for tumors distal to the angulus and tended to be stronger in women than in men. The results were similar across Laurén morphologic subtypes. CONCLUSIONS: These results strengthen the evidence of H. pylori infection as a risk factor in non-cardia gastric cancer. A negative association with H. pylori infection was found for cardia cancer.

The value of autopsy from a clinical point of view. A survey of 250 general practitioners and hospital clinicians in the county of Sør-Trøndelag, Norway.

An enquiry into clinicians' attitudes to autopsies was conducted by questionnaire sent to 166 general practitioners in the county of Sør-Trøndelag in Norway and to 186 clinicians working at the University Hospital of Trondheim. It was considered especially important for us to include general practitioners. As the result of a government decision taken at the end of 1994, autopsies requested by general practitioners on patients dying outside hospitals have from January 1995 been covered by national health insurance. Answers were obtained from 250 doctors: 110 general practitioners and 140 hospital physicians. One hundred and seventy-nine (73.1%, n=245) felt that the possibility of having autopsies performed was of great importance in their daily work. Autopsy was considered to be a very important means of quality assurance in the health care system by 158 (66.4%, n=238). One hundred and two (41.2%, n=247) answered that improvements in medicine and technology during the last decades had not reduced the importance of autopsy. One hundred and twenty-two (81.3%, n=150) felt that especially computer tomography (CT) had reduced the value of autopsy. Among the general practitioners, 73 (68.9%, n=106) welcomed the opportunity to have non-forensic autopsies performed on patients who died outside hospitals. Our study showed differences in the attitudes of clinicians towards autopsies, but our results still indicate that the value of autopsy for furthering clinical knowledge is acknowledged by most clinicians.

Neuroendocrine differentiation in human gastric carcinoma.

BACKGROUND: Distinguishing between neuroendocrine carcinoma and adenocarcinoma may be difficult. METHODS: In the current prospective study blood and tumor tissue from patients with gastric carcinoma were collected. The tissue was fixed in different ways to allow examination for neuroendocrine markers by multiple methods such as various histochemical and immunohistochemical methods and electron microscopy. Blood and tumor homogenates were examined by radioimmunoassay for specific hormones and general neuroendocrine markers. RESULTS: Based on examination of general neuroendocrine markers such as chromogranin A (by immunohistochemistry, Northern blot analysis, and tissue concentration), neuron specific enolase (immunohistochemistry) as well as electron microscopy, it was possible to conclude that approximately 10% of the tumors were actually neuroendocrine malignant tumors. Among these tumors, the enterochromaffin-like (ECL) cell was the most preponderant cell of origin (Sevier-Munger positive and serotonin negative immunoreactive tumor cells with secretory granules resembling those observed in normal ECL-cells). As reported previously, tumors of the diffuse type (according to the classification of Laurén) most often were reclassified as neuroendocrine carcinomas. CONCLUSIONS: The current study shows that neuroendocrine and particularly ECL cell-derived tumors are more common in the stomach than previously recognized.

[The value of autopsy in current health care. An analysis of autopsies performed during one year at the Regionsykehuset in Trondheim]. / Obduksjonens verdi i dagens helsevesen. En analyse av ett års obduksjonsmateriale fra Regionsykehuset i Trondheim.

We have reviewed the reports from 222 autopsies performed during one year (1994) at our Department of Pathology. The majority (74%) of all autopsies were performed on patients from the Department of Internal medicine at our hospital. Autopsy findings were correlated with the clinically suspected causes of death, as revealed by the death certificates and the clinical information in the written requests for autopsies. The direct cause of death, as found at autopsy, had been suspected by the clinicians in 70% of cases. The underlying cause of death, as found by the pathologists at autopsy, had been diagnosed by the clinicians in 75% of the cases. In 26 cases (12%) the underlying cause of death had neither been diagnosed nor suspected by the clinicians. In the last mentioned group, 77% of the patients were more than 70 years of age. In six cases where the underlying cause of death had not been diagnosed or suspected by the clinicians, the findings at autopsy were classified as type-1 findings. These are findings, if they had been known when the patient was still alive would probably have led to therapy that night have improved the prognosis.
