[In order to survey the frequency of hypoglycaemia and its awareness we investigated 91 insulin- treated diabetic women (48 pregnant and 43 non-pregnant) consecutively using 9 to 15 blood glucose measurements. Subjective hypoglycaemic symptoms of patients were registered by using a structured questionnaire. Biochemically proved hypoglycaemia has been found in two third of patients (62/91). One third of the patients had a loss of awareness, 23 had partial awareness and 19 were aware of hypoglycaemia. No significant difference were found according to age, diabetes duration, daily insulin dose/kg body weight, glycated haemoglobin levels and frequency of diabetic complications. Five standard cardiovascular autonomic reflex-tests were performed in 31 patients. Age, diabetes duration, frequency of diabetic complications of patients with evidence of autonomic neuropathy significantly surpassed that of having normal cardiovascular reflex-tests. Our results confirm from clinical-epidemiological aspect that hypoglycaemia unawareness is not invariably associated with cardiovascular autonomic neuropathy. ]

[The role of computer tomography and magnetic resonance imaging in organic neurological diagnosis]

KENÉZ József

[In the last two decades, neuroimaging became the basic investigative method in the diagnostics of organic neurology due to the rapid development of medical electronics. In the nineties called the "Decade of the Brain", the importance of these methods could hardly bee overestimated. The two outstanding investigations of neuroimaging are computer tomography (CT) and magnetic resonance imaging (MR). Surely in the near future the application of these investigations will be incorporated in the Hungarian healthcare system as well. In this review all the points of view are collected on the basis of neurologic clinical symptomatology to help clinicians to decide, which method and when has to be chosen to gain the most valuable and detailed information on the quickest way, with less risk, and for the least amount of money ]

[Five cases of operated atrial tumors]


[Between November 1986. and June 1989. five patients underwent excision of an atrial tumour. Two of the patients had previous peripheral embolization, two had cardiac symptoms and one was symptomless. All the tumours were demonstrated by means of echocardiography and in four cases by angiocardiography as well. Four of them were left atrial tumors and one in the right atrium. The tumors were succesfully removed in all patients: in three cases by shaving them from the endocardium, in one case by excising a portion of atrial septum and in one case with a margin of normal atrial wall. Histological examination showed thrombus in one case. All patients survived operation and left hospital in good conditions. During the follow up there were no cardiac complication or local recurrence.]

[Hypothesis of natural birth]


[It's supposed by the author that there exists a natural birth. According to his assumption in every woman's subconscionsness there is the code of the natural birth's behaviour (CODE), which can be spontaneously mobilized in the gravid woman. Putting into practice whichever way for the preparation of the birth, this mobilization can be advanced and in this way the child-bearing women's behaving repertory during their birth is increasing and it's drawing near to the equivalent of its own code. This may be the explication of the success and result of the alternative obstetrics end the preparing programs for the different births. The psychological explanation of the theory is given on the basis of C. G. Jung's activity.]

[Report on gastroenterological endoscopic activity in Hungary in 1989]

NAGY György, JUHÁSZ László

[The Endoscopic Section of the Hungarian Gastroenterological Society, under the leadership of Professor Wittmann, published an annual report on the status and development of endoscopy of the digestive organs in Hungary from 1975. In 1976, the report reported 27453 examinations performed at 75 endoscopic workplaces with 163 instruments. The 1987 survey already included 139496 examinations (36623 in Budapest, 102873 in the countryside) performed at 117 workplaces (37 in Budapest, 80 in the countryside) with 565 instruments (219 in Budapest, 346 in the countryside). In a statistical summary of 13 years, 968090 endoscopic examinations resulted in 389 (0.4 per thousand) complications, of which 71 (7 per 100,000) were fatal. The collection of study data was interrupted with the death of Professor Wittmann. ]

[Insulin aspart (B28 Asp-insulin), which is produced by recombinant DNA technology, is a fast-acting insulin analogue. Due to the aspartate for proline substitution at position 28 of the Bchain, the insulin molecule's tendency for selfassociation is diminished, therefore, insulin aspart rapidly dissociates into dimeric and monomeric forms and absorbs quickly and easily after subcutaneous administration. Compared to human regular insulin, insulin aspart has a faster onset of activity, a higher plasma peak and a shorter duration of action. Overall, the pharmacokinetic profile of insulin aspart better mimics the physiological postprandial insulin secretion. Therefore, insulin aspart can be used for prandial insulin substitution in order to decrease postprandial blood glucose excursion. It should be administered immediately before meals, but some observations suggest that it can also be used after finishing meal. This allows a more flexible lifestyle for patients. Insulin aspart can be used in both type 1 and type 2 diabetes. Compared to regular human insulin, a moderate decrease in the HbA1c values and fewer nocturnal hypoglycaemic events are expected from insulin aspart use. Insulin aspart is appropriate for pump treatment as well. It has recently been approved for use in pregnancy, whereas for children and adolescents the expected benefits should be weighed against the more modest clinical experience available. Similarly to other insulin analogues, results of long-term clinical investigations with insulin aspart with regard to the development of complications are not yet available.]

[Switching from human basal insulin to once daily insulin detemir in type 2 diabetic patients treated by basal-bolus regimen - Results from the LEONCET2, an observational, prospective, multicenter study]


[Insulin analogues have been developed in order to overcome some drawbacks of human insulins. Switching from a human insulin-based basal- bolus regimen to once daily detemir could result in improved metabolism and increased safety of the therapy. We assessed the effects of switching from human NPH-insulin to once daily detemir insulin in patients with type 2 diabetes mellitus treated with a basal-bolus insulin regimen. We evaluated the data of 1,474 patients with diabetes (age: 59.1±9.8 years, body weight 89.6±8.6 kg, BMI 31.6±5.4 kg/m2) in an observational, prospective, 24-week, multicenter study. All patients were treated with a basal-bolus regimen consisting of human NPH as basal insulin and a human or analogue insulin as bolus insulin. After enrollment, patients received once daily detemir insulin instead of NPH-insulin, while treatment with bolus insulin was continued. Patients were examined at weeks 12 and 24. By week 24, the mean HbA1c value, irrespective of BMI-categories, decreased significantly (p<0.0001) from 8.63±1.01% by 0.79±0.63%. Fasting blood glucose level decreased from 8.86±1.78 mmol/l to 7.09±1.31 mmol/l; p<0.0001). The target level of HbA1c (<7.0%) was reached by 194 patients (13.1%). The patients’ body weight decreased significantly by week 12 (-0.69±2.00 kg; p<0.0001) and by week 24 (-1.28±2.80 kg; p<0.0001). The changes were more pronounced in higher than in lower BMI-categories (p for trend <0.0001). The mean daily doses of basal insulin were increased from 0.28 IU/kg to 0.33 IU/kg while those of bolus insulins were not changed. The rate of severe hypoglycaemic events decreased significantly (p=0.048) from 2.95 [daytime 1.02, nocturnal 1.93] to 0.06 [daytime 0.04, nocturnal 0.02] episodes/patient-year. In patients with type 2 diabetes mellitus treated with basal-bolus regimen, switching from human basal insulin to once daily insulin detemir results in a significantly improved metabolism, as well as fewer hypoglycaemic events and decreased body weight. Nevertheless, the low rate of patients reaching the glycaemic target implicates that some factors other than an appropriate basal insulin substitution have a role in achieving an optimal metabolic control.]

[Efficiency and safety of biphasic aspart insulin therapy in clinical studies]

GERŐ László

[Six-to-eight years after the diagnosis of type 2 diabetes the majority of patients require insulin treatment. Premixed insulin therapy provides an insulin profile that is closer to the physiological profile than that achieved by basal insulin supplementation and, in some cases, may serve as an alternative treatment in patients for whom intensified insulin therapy is unsuitable. However, if premixed human insulins are used, nocturnal hypoglycaemia occurs relatively frequently. Furthermore, patients must keep a lag-time of 30-45 minutes between the injection of insulin and eating. In contrast, if premixed insulin analogues are used, there is no need for such lag-time and both nocturnal and severe hypoglycaemia are less frequent than with human premixed therapy. The superiority of premixed insulin analogues compared with premixed human insulin therapy has been confirmed by a number of prospective, randomised controlled trials and retrospective analyses. The author summarises the results of these studies, emphasising the beneficial effects of premixed insulin analogues in the therapy of type 2 diabetes.]
