[The case history of a 47-year-old woman is reported. From her puberty, diffuse muscle pains and cramps appeared in her musclers after physical activities, with no complaints during rest. She was submitted to scalenotomy because of pains in her right arm, without any influence of her condition. Myopathy was detected by electromyography and muscle biopsy. Later, hypophosphataemia and diabetes mellitus were found by repeated laboratory investigations. Detailed internal medical, endocrinological and biochemical investigations were not able to demonstrate any other abnormalities. The ultrastructure of the muscle exhibited vacuolar degeneration. Phosphate supplementation resulted in clinical improvement and normalization of the laboratory findings. Our results demonstrate the pathogenetic background of muscle damage and correlations between the phosphate metabolism, diabetes mellitus, myopathy, and tubulopathy.]

[Patient characteristics at the stroke unit of a clinical department of neurology during a 12-month period - methods of database management, demographic characteristics and inhospital mortality]


[Hungary is among the countries with the highest rates of stroke mortality. Accuracy of data in international statistical reports have been crlticized by several authors. The aim of the present study was to give a methodological description of the database, to report basic patient characteristics and to discuss causes of discrepancies between national and hospital stroke morbidity and mortality data. Data from a stroke unit with a catchment area of 210 000 inhabitants were used to create a database from about 100 parameters per patient discharged from the stroke unit during a 12-month period. During this period 505 patients with acute stroke were treated at the stroke unit. Of the patients admitted 15% did not have stroke. Fatality among inpatients with acute stroke was 18.6% (n=94). Assuming that all stroke patients of the catchment area were treated at the stroke unit and that stroke mortality in the catchment area equals that of the national value, 410 deaths should have occurred at the unit. The discrepancy between the number of the expected and detected stroke fatality cases might imply that either a large number of stroke patients from the catchment area do not reach the stroke unit, or actual stroke mortality is lower in our region than the national average. To examine these hypotheses, a population based prospective study should be performed. ]

[Experiences of surgically treated temporal epileptic patients - multicentre study ]

BALOGH Atilla, BORBÉLY Katalin, CZIRJÁK Sándor, HALÁSZ Péter, JUHOS Vera, KENÉZ József, VAJDA János

[Our experiences on surgically treated temporal lobe epileptic patients are presented. Involved in the disease are the process of preoperative investigations, clinical data, types of operation and their indications, and the postoperative controls. Pre- and postoperative data of 36 surgically treated, intractable temporal lobe epileptic patients were analysed. A postoperative follow-up of longer than two years was carried out on 24 patients. The experiences of these patients on postoperative seizure frequency were evaluated using Engel's classification. Among these 24 temporal lobe epileptic patients 19 are seizure free (Engel I.), the seizure frequency significantly decreased in 3 of them (Engel II.), in the case of 2 patients the number of seizures was reduced (Engel III.). Our experiences show that neurosurgical investigation seems to be an increasingly useful, alternative way for treating intractable temporal lobe epileptic patients.]

[Lumbar pseudoradicular pain part 1: anatomical principles]

KASÓ Gábor, DÓCZI Tamás, DÁVID Károly

[Most low back and leg pain, caused by degenerative disorders of the lumbar spine can be classified as referred (projected) pain. One of the types of referred pain is pseudoradicular pain originating from the characteristics of innervation of the spinal motion segment. Ventral parts of the spinal motion segment are supplied by the sinuvertebral nerve and the sympathetic nervous system, while the dorsal compartment is innervated by dorsal rami of the spinal nerves and both systems show considerable segmental overlap]

[Gasoline caused hexacarbon polyneuropathy - description of five cases]

VIDA Zsuzsanna, FOLYOVICH András, GÁCS Gyula

[Based on five cases a description is given n-hexane induced polyneuropathy caused by laundry cleaning gasoline, a kind of exposition that has not been published up till now. The symptoms (subacute sensomotor polyneuropathy) and the peculiar course (further deterioration after the exposition has ceased) of hexacarbon polyneuropathy caused by gasoline were similar to that of other cases induced by other n-hexane containing materials such as diluting agents, glues, lacquers etc.]

[Short- term video EEG analysis in a useful tool in the diagnosis of epileptic phenomena]


[Short-term (30–120 min) video- EEG recording and split-screen analysis is a very useful tool in investigating short- lasting epileptic or non- epileptic phenomena. The authors use this technique in different clinical situations as follows: frequent seizure- like episodes of suspected or proven epileptic etiology, with special reference to absence like and myoclonus- like episodes; motor manifestations, paroxysmal psychic phenomena, and fits induced by visual stimulation. Further indications were as follows: long-lasting pathological stupor states of suspected epileptic origin, long-lasting EEG discharges with unclear clinical correlations, precise analysis of partial epileptic seizures. The results show that, depending on patient selection, video- EEG analysis significantly contributed to precise diagnosis of epileptic seizures as well as to differentiation between epileptic and nonepileptic fits. In a few cases, rare, unsuspected epileptic conditions could only be identified by means of video- EEG analysis. The paper has been completed with a few brief illustrative case reports.]

[Bone mineral density and diabetes mellitus - First results]


[INTRODUCTION - Data on bone mineral density (BMD) in diabetes mellitus are contradictory in the literature. Early studies described a decreased bone mineral density in type 1 diabetes mellitus (T1DM), but recent studies report no osteopenia in T1DM.The BMD may depend on the quality of treatment for diabetes mellitus and on the presence of chronic complications. In type 2 diabetes mellitus (T2DM) the BMD is not decreased, occasionally it can even be increased. PATIENTS AND METHODS - Bone mineral density was measured in 122 regularly controlled diabetic patients (T1DM: n=73, mean age: 43.6±11.1 years,T2DM: n=49, mean age: 61.8±9.8 years) by dual energy X-ray absorptiometry at the lumbar spine and at the femur. Results were compared to those of 40 metabolically healthy control persons with a mean age of 47.5±11.9 years.The patients’ carbohydrate metabolism was assessed by the average HbA1c level of the last three years.These values were 7.9±1.4 % in T1DM, and 7.5±1.7 % in T2DM. BMDs were classified based on the T-score and Z-score using the WHO criteria. RESULTS - There was no significant difference in T1DM or in T2DM compared to the reference group in the prevalence of either osteoporosis or of osteoporosis and osteopenia combined. CONCLUSION - BMD was not found to be decreased in patients with well-controlled metabolism compared to healthy controls.]

[The importance of hypertension in type 2 diabetes mellitus, the method of continuous blood pressure control and patient’s careas well as the forms of non-drug and drug therapy have been disclosed by presenting therapeutical recommendations from American, European scientific societies and international organizations. It has been established that the principles of care and treatment of hypertonia have basically remained unchanged in diabetes all over the world, despite the recent widespread debate over the interpretation of normal blood pressure and the consideration of the benefits of intensive or standard treatment.]

[Diagnosis and therapy of mitochondrial diseases]

PÁL Endre

[Mitochondrial diseases are a significant part of neuromuscular diseases. Majority of them is multisystemic disorder. The diagnosis can be established in more and more cases. Beyond the routine neurological examination imaging methods (MRI and MR-spectroscopy) and electrophysiology (EMG, ENG, EEG, evoked potential tests) might be helpful in setting the diagnosis. Raised blood lactate level supports the diagnosis. Muscle biopsy demonstrates mitochondrial abnormalities in the majority of cases. The positivity of genetic tests is low, because the amount of mitochondrial DNA alterations is different in tissues. Therefore other tissue than blood (mainly muscle) is necessary for genetic tests. The other reason is that the respiratory chain is under double -mitochondrial and nuclear - genetic control, and testing the nuclear genes are available only in selected laboratories. The treatment is limited, mainly symptomatic.]

[Necrotising autoimmune myopathy showing dermatomyositis symptoms during persistent statin treatment]

TIHANYI László, SÜTŐ Gábor, VERESS Gábor

[INTRODUCTION - Dermatomyositis is an idiopathic autoimmune disease. Diagnosis has to be confirmed by biopsy, because clinical symptoms can be similar to those in other myopathies. CASE REPORT - The authors describe the development of dermatomyositis in a 59- year-old man. The patient had a heart attack in 1988. He had been taking simvastatin for three years and atorvastatin since 2002. In June 2008 he complained of myalgia and weakness, became physically very inactive but visited our specialist only half a year later. Laboratory examinations showed a substantial increase of CK, CKMB, LDH and HBDH with troponin T positivity (troponin I was negative). A subsequent biopsy confirmed dermatomyositis. Treatment with azatioprine and methylprednisolone and suspending statin therapy resulted in the regression of his clinical symptoms, his muscles gradually became stronger and his laboratory values normalised. CONCLUSION - During statin treatment in 5% of the cases myopathy can occur, which might develop into amore severe inflammatory disorder.]

[The prevalence of type 2 diabetes mellitus in the Hungarian population with hypertension]

KÉKES Ede, PÁL László, SCHANBERG Zsolt, KISS István

[Authors had found diabetes mellitus type 2 in 30% of 38 886 hypertensive patients (stadium I-III). Diabetes was more frequent in case of women under 30 years. Subsequently all age groups (from 40 to 80 years) incidence was more frequently (p<0.01-0.001) in men, above 80 years again a higher ratio was in women. Presence of diabetes was correlated to rate of BMI value and systolic, diastolic pressure as well. In women - above 140 mmHg systolic pressure - the elevation was exponential. We have found a significant correlation between fasting glucose and waist. Reaching the target blood pressure is not a simply task in hypertensive patients with diabetes. The 140/90 mmHg was reached in 34.2%, 90 mmHg diastolic blood pressure in 62.3%, but the required 80 mmHg only in 16.4% of cases. Achieve the target value was quite different in the different region of our country. The major cardiovascular complications (stroke, renal disease, myocardial infarction, peripheral artery disease) have suffered a higher rate in the hypertensives with diabetes compered to hypertensives without diabetes.]
