Twenty-five years after Billroth II gastrectomy for duodenal ulcer

One thousand twenty-five patients underwent a Billroth II resection for duodenal ulcer between 1948 and 1956. The operative mortality rate was 2.4%. At follow-up between 22 and 30 years later, 522 had died and 423 patients were traced. Recurrent ulcer appeared in 2.6% of the cases. Postgastrectomy symptoms occurred with the following frequency: dumping 10%, diarrhea 5%, vomiting 7%, and pain 4%. Anemia developed in 18%, hypoalbuminemia and hypocalcemia in 40 and 15%, respectively. Eleven percent had lost more than 10 kg in weight. Tuberculosis was found in 3% of the cases. While 90% of the patients were satisfied with the result, 10% were failures. The overall mortality rate was significantly increased because of suicide. Gastric carcinoma was the cause of death no more often than expected.

Resumen En años anteriores la gastrectomía Billroth II fue un procedimiento operatorio de uso común en el tratamiento de la úlcera duodenal. Los promisorios resultados de la vagotomía con drenaje, vagotomía y antrectomía y, especialmente, la vagotomía de células parietales han reducido el rol de la resección de tipo Bilroth II. El propósito del presente estudio es describir los resultados a largo plazo en un grupo de pacientes sometidos a gastrectomía Billroth II por úlcera duodenal aproximadamente 25 años antes.Entre 1948 y 1956, 1 025 pacientes consecutivos, 810 hombres y 190 mujeres, fueron sometidos a resección Billroth II por úlcera duodenal. La mortalidad operatoria fué de 2,4%. Durante el período de seguimiento entre 22 y 30 años, 522 pacientes habían muerto y 423 pacientes pudieron ser ubicados para seguimiento. Síntomas de post-gastrectomía fueron observados con la incidencia siguiente: dumping 10%, diarrea 5%, vómito 7% y dolor 4%. La anemia se presentó en el 18%, hipoalbuminemia e hipocalcemia en el 40% y en el 15% respectivamente. Se presentó tuberculosis en el 3% de los casos. El 90% de los pacientes se mostraron satisfechos con el resultado de la operación, pero el 10% restante indicó la falla del tratamiento. La mortalidad global resultó significativamente incrementada debido a una alta incidencia de suicidio. El carcinoma gástrico fue causa de muerte con una frecuencia no aumentada, o sea que no se encontró un mayor riesgo de muerte por carcinoma de esófago o del remanente gástrico.

Résumé De 1948 à 1956, 1 025 malades atteints d'ulcère duodénal ont subi une opération de Billroth II. La mortalité a été de 2,4%. Au cours de l'évolution de 22 à 30 ans après l'intervention, 522 opérés sont décédés et 423 ont été suivis. La fréquence de la récidive a été de 2,6%. Les symptômes après gastrectomie ont atteint les taux suivants: dumping 10%, diarrhée 5%, vomissements 7%, douleur 4%. L'anémie a été constatée dans 18% des cas, l'hypoalbuminémie dans 40% des cas et l'hypocalcémie dans 15% des cas, onze pour cent des opérés ont accusé une chute pondérale supérieure à 10 kg; 3% ont présenté une tuberculose. Au total 90% des malades se sont déclarés satisfaits de l'intervention, encore que certains opérés se soient suicidés, ce nombre intervenant dans la mortalité globale. La mortalité par cancer n'a pas dépassé le taux accusé par la population en général.

Dietary Supplementation with Selenium and Coenzyme Q10 Prevents Increase in Plasma D-Dimer While Lowering Cardiovascular Mortality in an Elderly Swedish Population

A low intake of selenium is associated with increased cardiovascular mortality. This could be reduced by supplementation with selenium and coenzyme Q₁₀. D-dimer, a fragment of fibrin mirroring fibrinolysis, is a biomarker of thromboembolism, increased inflammation, endothelial dysfunction and is associated with cardiovascular mortality in ischemic heart disease. The objective was to examine the impact of selenium and coenzyme Q₁₀ on the level of D-dimer, and its relationship to cardiovascular mortality. D-dimer was measured in 213 individuals at the start and after 48 months of a randomised double-blind placebo-controlled trial with selenium yeast (200 µg/day) and coenzyme Q₁₀ (200 mg/day) (n = 106) or placebo (n = 107). The follow-up time was 4.9 years. All included individuals were low in selenium (mean 67 μg/L, SD 16.8). The differences in D-dimer concentration were evaluated by the use of T-tests, repeated measures of variance and ANCOVA analyses. At the end, a significantly lower D-dimer concentration was observed in the active treatment group in comparison with those on placebo (p = 0.006). Although D-dimer values at baseline were weakly associated with high-sensitive CRP, while being more strongly associated with soluble tumour necrosis factor receptor 1 and sP-selectin, controlling for these in the analysis there was an independent effect on D-dimer. In participants with a D-dimer level above median at baseline, the supplementation resulted in significantly lower cardiovascular mortality compared to those on placebo (p = 0.014). All results were validated with a persisting significant difference between the two groups. Therefore, supplementation with selenium and coenzyme Q₁₀ in a group of elderly low in selenium and coenzyme Q₁₀ prevented an increase in D-dimer and reduced the risk of cardiovascular mortality in comparison with the placebo group. The obtained results also illustrate important associations between inflammation, endothelial function and cardiovascular risk.     

CNS-induced natriuresis, neurohypophyseal peptides and renal dopamine and noradrenaline excretion in prehypertensive salt-sensitive Dahl rats

To identify defects in the salt-sensitive Dahl rat (Dahl-S), the natriuretic, catecholaminergic and pressor responses to 60-min elevation of the cerebroventricular sodium concentration (CNS-induced natriuresis) were compared between prehypertensive salt-sensitive Dahl-S and salt-resistant Dahl rats (Dahl-R). The plasma concentrations of the rat natriuretic hormone oxytocin, which has implications for the development of hypertension, and vasopressin (AVP) were also measured. Basal sodium and catecholamine excretion and mean arterial blood pressure (MAP) were similar in both strains. Sodium excretion during CNS stimulation increased more than 15-fold in Dahl-R but only 10-fold in Dahl-S. Dopamine excretion increased only transiently and similarly in both strains. Noradrenaline excretion and response to CNS stimulation were similar, suggesting a comparable sympathetic nervous activity between the strains. MAP increased comparably in Dahl-R and Dahl-S. Plasma AVP concentration was similar in both strains while plasma oxytocin concentration after CNS stimulation was more than 2-fold higher in Dahl-S than in Dahl-R. In conclusion, the prehypertensive Dahl-S has an attenuated natriuretic response to elevations of the cerebroventricular fluid sodium concentration and a higher plasma level of the natriuretic hormone oxytocin. Dopamine is not a mediator of CNS-induced natriuresis in neither strain. The attenuated natriuretic response may partly explain the salt-sensitivity in Dahl-S, and the higher plasma oxytocin value may either represent an effort to compensate for the deficient natriuretic response or reflect a primary defect in this system. Due to the known involvement of oxytocin in central MAP regulation in some hypertensive animal models, the findings warrant further investigation.     

The reliability of auscultatory measurement of arterial blood pressure. A comparison of the standard and a new methodology

In 48 individuals with a wide range of arm circumferences blood pressure measured indirectly with two different cuffs was compared to direct intraarterial measurements. The two cuffs were a standard size cuff (12 X 35 cm) and a newly developed cuff, containing three rubber bags of different sizes, which automatically selects the appropriately sized bag in relation to arm circumference (Tricuff, Pressure Group AB, Sweden). The Tricuff correctly placed 42 of the 43 patients in the "normotensive" range, ie, diastolic blood pressure less than 90 mm Hg, whereas the standard cuff put only 33 of 44 patients in this range (P less than .005). The discrepancy was not only due to the expected better performance in patients with obese arms, but also in the subgroup of patients with arms in the range 22 to 31 cm, in which group both cuffs would measure blood pressure with a 12 cm wide rubber bag. The number of correctly identified "normotensive" patients was noticeably higher with the Tricuff than with the standard cuff (30/31 v 25/32, P = .053). The better specificity of the new cuff thus offers an improvement over the standard cuff. There are several potential clinical advantages of this, mainly that the risk of erroneously labelling normotensive individuals as hypertensive is reduced.     

Androgen treatment of abdominally obese men

Middle-aged men with abdominal obesity were treated in a double-blind study with moderate doses of transdermal preparations of testosterone (T), dihydrotestosterone (DHT), or placebo. This resulted in moderately elevated T concentrations and marked decreases in follicle stimulating and luteinizing hormones in the group treated with T, while the DHT group showed elevated DHT, markedly lower T values, and less diminution of gonadotropin concentrations. In the group treated with T visceral fat mass decreased (measured by computerized tomography) without significant changes in other depot fat regions. Lean body mass did not change. In the group treated with T, glucose disposal rate, measured with the euglycemic hyperinsulinemic clamp method, was markedly augmented. Plasma triglycerides, cholesterol, and fasting blood glucose concentrations as well as diastolic blood pressure decreased. There were no such changes in the DHT or placebo treatment groups. The men treated with T reported increased well-being and energy. In none of the groups did prostate volume, specific prostate antigen concentration, genito-urinary history, or urinary flow measurement change. It is suggested that supplementation of abdominal obese men with moderate doses of T might have several beneficial effects.     

Cardiac arrest during caesarean section

A case is described of a previously healthy obese woman in her fourth pregnancy who presented for caesarean section due to cephalopelvic disproportion (CPD). Forty minutes after a spinal anaesthetic a healthy child was delivered. Shortly after the injection of ergometrine and Syntocinon into the uterus, the patient described a general feeling of discomfort which was followed by convulsions and cardiac arrest. Resuscitation was successful and the circulation was restored. However, it was difficult to maintain oxygenation and the patient was mechanically ventilated for 24 hours and subsequently supplementary oxygen therapy was given for three days. A pulmonary scintigram on the fourth day after delivery showed large uptake defects indicative of pulmonary embolism. The patient recovered completely and was discharged home after two weeks. Differential diagnosis and measures to reduce the risk of deep vein thrombosis (DVT) are discussed.
