Surgical treatment of cavernous haemangiomas of the liver

Cavernous haemangiomas of the liver were surgically treated in 36 women and 14 men over a 10-year period. The tumours were solitary in 42 cases and multiple in 8. Locations were the right lobe in 39 cases, the left one in 5 and both lobes in 6. The size of the tumours ranged from 0.4 to 14 cm in diameter. Enucleation of tumours was carried out in 29 cases, an atypical liver resection in 19 cases, anatomical lobectomy in 2 cases and a right trisegmentectomy in 1 case. There was no mortality. Morbidity rate seems to be lower in patients who underwent enucleation. The authors indicate the importance of enucleation for removal of liver haemangiomas of various sizes.

Chirurgische Behandlung kavernöser Hämangiome der Leber

Zusammenfassung Über einen Zeitraum von 10 Jahren wurden kavernöse Hämangiome der Leber bei 36 Frauen und 14 Männern chirurgisch behandelt. Bei 42 Patienten waren die Tumoren solitär, bei 8 multipel. Sie waren in 39 Fällen im rechten, bei 5 Patienten im linken und bei 6 in beiden Leberlappen lokalisiert, ihr Durchmesser betrug 0,4 bis 14 cm. In 29 Fällen wurde eine Enukleation, in 19 eine atypische Leberresektion, in 2 eine anatomische Lobektomie und in einem Falle eine rechtsseitige Trisegmentektomie durchgeführt. Die Mortalität war gleich Null; die Morbiditätsrate scheint bei den Patienten geringer, die mit Enukleation behandelt wurden. Der Beitrag hebt die Bedeutung der Enukleation zur Beseitigung von Leberhämangiomen unterschiedlicher Größe hervor.

     

Surgical treatment of low fistulous forms of anal atresia using postero-sagittal approach in children

The problems of surgical treatment of the low fistulous forms of anal atresia in children with the use of postero-sagittal approach are considered. A modification of this method is described. The postoperative results are presented, and the possible complications as well. A conclusion about the advantages of the operative approach described is made.     

Pharmacokinetics, hepatic biotransformation and biliary and urinary excretion of bromosulfophthalein (BSP) in an experimental liver disease mimicking biliary cirrhosis

We studied the hepatic handling of bromosulfophthalein in healthy rabbits with hepatic coccidiosis 28 days after an experimental infection with sporulated oocysts of Eimeria stiedai, an experimental model of liver disease histopathologically resembling primary biliary cirrhosis in man. A pharmacokinetic study of the results was performed following a multicompartmental model with 7 transfer constants to describe the physiological disposition of the dye. The study showed that the plasma disappearance, distribution volume (Vi), hepatic biotransformation and the biliary and urinary elimination of conjugated (BSPc) and unconjugated (BSPu) bromosulfophthalein were markedly altered. Whereas Vi and urinary excretion of the dye were significantly increased, the hepatic clearance, biotransformation and biliary excretion of BSPc and BSPu were drastically reduced in infected rabbits. Satisfactory agreement was obtained between the experimental and estimated data, particularly those relating to biotransformation clearance and biliary and urinary excretion of the dye. These results demonstrate that severe liver disease in rabbits with histopathological liver alterations resembling several hepatic dysfunctions in man markedly reduce hepatic uptake, metabolism and biliary excretion of a xenobiotic such as BSP.     

Hypertension in developing countries

Population surveys carried out since the 1970s in 15 developing countries including 23 population groups show that the prevalence of hypertension ranges from as low as 1% in some African countries to over 30% in Brazil. A trend analysis of the mortality statistics for 35-74 year-olds from 16 countries in which data are available shows a downward trend in mortality from hypertension and cerebrovascular diseases in most of these countries. In spite of the current low prevalence in some countries, the total number of hypertensives in the developing world is high, and a cost assessment of possible antihypertensive drug treatment indicates that developing countries cannot afford the same drug treatment levels as developed countries.     

克隆特含漱液毒性实验研究

目的探讨克隆特会激液对实验动物的毒性反应。方法小鼠灌胃给药、大鼠局部给药，连续观察14d内动物的毒性反应；将克隆特含激浪涂数干实验动物的完整和破损皮肤上，观察局部刺激作用、皮肤过敏反应；将克隆特含激法0．1ml缓慢注入明道内，每日一次，连续1wk，观察用道粘膜组织有无充血、水肿现象。结果克隆特合漱液小鼠灌胃30ml·kg-1体重（含甲硝吐150mg）无毒性反应；局部用药量为5ml·kg-1体重（合甲硝唑25mg）亦未出现毒性反应；对皮肤及明道粘膜无明显刺激作用，亦未见皮肤过敏反应。结论克隆特合漱法局部用药较安全。     

The effect of preconceptional multivitamin supplementation on the menstrual cycle

The database of the Hungarian randomised controlled trial of periconceptional multivitamin supplementation for the prevention of neural-tube defects was used to evaluate the length of the pre- and postovulatory phases of the menstrual cycle before and during multivitamin supplementation. The female cycle was more regular (i.e., the variance was lower) during the multivitamin supplementation.     

Antibiotic prophylaxis in surgery for hip fractures

Totally, 185 patients, operated on for a fresh hip fracture, were randomly allocated to either methicillin antibiotic prophylaxis or no prophylaxis and followed for 1 month. Two superficial wound infections were recorded in the prophylaxis group and one in the control group. Prophylactic use of antibiotics in surgery for hip fractures seems unnecessary provided strict aseptic routines in the operating room are followed.
