Epilepsies with astatic seizures of late onset.

In 17 patients with a long course of epilepsy astatic seizures became apparent after the age of 14 years. In the patients' childhood astatic seizures had not been observed. The patients suffered from epilepsies with absences and awakening grand mal or psychomotor fits and sleeping grand mal. The EEG revealed spike-wave variant and spike-and-wave complexes as in the Lennox-Gastaut syndrome. Age dependency of Lennox-Gastaut syndrome is discussed. The described type of epilepsy can be understood as a "Lennox-Gastaut syndrome of late onset".     

Effect of doxazosin on insulin sensitivity in hypertensive non-insulin dependent diabetic patients

Summary The effect of doxazosin, an a,-adrenoceptor blocking drug, on blood pressure, sensitivity to insulin and serum lipids has been evaluated in 14 hypertensive, non-insulin dependent diabetic patients. The dose was titrated individually upwards from 1 mg until the diastolic blood pressure was below 90 mm Hg, side-effects precluded further dosage increase or the maximum daily dose of 16 mg was achieved.After 12 weeks of treatment (mean doxazosin dose 5.6 ± 5.1 mg daily), the supine and standing diastolic blood pressure of the patients had declined by about 7 mmHg, whereas their systolic blood pressure and heart rate were not significantly changed. The metabolic clearance rate of glucose increased from 2.35 to 3.37 ml - min^–1 - kg^–1 during treatment, suggesting improved sensitivity to insulin. Fasting plasma glucose was 11.9 mmol·1^–1 before and 10.9 mmol·l^–1 after doxazosin therapy (NS). Serum electrolytes and lipids did not change significantly but serum uric acid decreased from 305 to 281 mol · 1^–1 Doxazosin may be a useful alternative for the treatment of hypertension in NIDDM patients.     

Das Tumorrezidiv am Hals nach papillarem Schilddrüsenkarzinom Eine statistische Analyse zur Rezidivwahrscheinlichkeit nach Radikaloperation

Zusammenfassung 308 Patienten mit papillärem Schilddrüsenkarzinom (82,6% des Gesamtkrankengutes, Operation 19522–1987), die postoperativ als tumorfrei eingestuft worden waren, wurden retrospektiv analysiert. Die Beobachtungszeit reicht von 1 Monat bis zu 29,4 Jahren (mediane Beobachtungszeit 4,58 Jahre). Bei 32 Patienten (10,4%) wurde ein Tumorrezidiv am Hals diagnostiziert (lokal und/oder regionär). 8 davon sind am Ende der Beobachtungszeit nicht tumorfrei, 6 sind am Tumor verstorben (tumorbedingte Todesrate 18,8%, relative Mortalität 66,7%, im Gesamtmaterial 2,9% bzw. 29,0%). Die kumulative Rezidivwahrscheinlichkeit beträgt 9,98% nach 5 und 16,98% nach 10 Jahren. Die statistische Analyse der Rezidivwahrscheinlichkeit erfolgte nur an Patienten, die mindestens 5 Jahre beobachtet wurden oder innerhalb dieses Zeitraumes verstarben. Als Einflußgrößen wurden neben Alter and Geschlecht, tumorstadium und histologische Kriterien des Tumors berücksichtigt. Als bestimmend für das Auftreten eines Rezidivs nach 5 Jahren Beobachtungszeit erweisen sich der Status der regiondren Lymphknoten, der Differenzierungsgrad des Tumors und das Geschlecht der Patienten. Zur Verbesserung der Rezidivrate wird eine abgestufte therapeutische Radikalität in Abhängigkeit von den Einflußgrößen empfohlen.

Cervical tumour recurrence after papillary thyroid carcinoma. A statistical analysis on the recurrence after potentially curative surgery

Summary 308 cases of papillary thyroid carcinoma (82.6% of our patients operated on between 1952 and 1987) who had undergone potentially curative surgery were analysed postoperatively. The follow-up ranges from 1 month to 29.4 years (median 4.58 years). In 32 cases (10.4%) a cervical tumour recurrence (local recurrence and/or cervical lymph nodes) was found. 8 of these are not free of tumour at the end of the follow-up, 6 had died of thyroid carcinoma (case fatality rate 18.8%, mortality rate 66.7%, in the entire material 2.9% and 29.0% respectively). The cumulative recurrence rate is 9.98% after 5 years and 16.98% after 10 years. A statistical analysis of the probability of recurrence was carried out only for patients who could be followed at least 5 years or those who died within 5 years. Age, sex, stage of tumour and histological criteria were taken into account as statistical variables. The state of cervical lymph nodes, the differentiation of the tumour and the patients' sex turned out to be determining factors for tumour recurrence after 5 years. In order to improve the recurrence rate a differentiated surgical radicality, depending on the above mentioned variables, is recommended.

     

Health and unhealth in chronic disease

When health is defined from a holistic view, traditional measures of control in diabetes, such as analysis of blood glucose or HbA1c, are of limited use as indicators of health and unhealth. On the other hand, evaluation of attitudes and certain personality variables might provide guidance both in discovering unhealth and in creating individual self-care programmes for its treatment. In the present study the subjective experience of health and unhealth was studied in a defined population of patients with insulin dependent diabetes mellitus (IDDM). The patients could be divided into three categories: a) those not abandoning important goals because of their diabetes, b) "adapted abandoners" and, c) those abandoning vital aspects of life. On the basis of the findings, the question of how "problem patients" can be identified and treated is discussed.     

Effects of theβ-adrenoceptor antagonists acebutolol and metoprolol on sleep pattern in normal subjects

Summary The effects of acute introduction and withdrawal of 2 new -adrenergic blockers, acebutolol and metoprolol, on sleep in normal subjects were investigated. Both the subjective effects of the drug and EEG sleep variables were determined during a baseline period with placebo and in relation to the drug. The results showed that neither drug had a significant effect on sleep pattern in normal subjects. However, a transient effect on certain sleep parameters was seen on the first night of drug administration, with complete return to baseline, on the following night without any evidence of rebound. Possible mechanisms to explain the central actions of -adrenergic blockers are briefly discussed.
