[Letters - Spontaneous pneumothorax]


MARCH 30, 1994

Lege Artis Medicinae - 1994;4(03)

[Dear Editorial Team! In the 30 November 1993 issue, AC Miller and JE Harvey's "Guidelines for the management of spontaneous pneumothorax" was published as a position paper of the British Thoracic Society. It may seem an ungrateful undertaking to enter into a debate with the principles of such a venerable and long-established society.]

[Hormone replacement therapy from a gynaeco oncological point of view]


[In Hungary, hormone replacement therapy (HRT) has been used more extensively in the last few years. The benefits of HRT in cardio vascular diseases, osteoporosis and quality of life have been well established. Breast cancer and endometrial carcinoma have been considered as contraindications for HRT. A reappraisal of this practice is necessary since we have no evidence that HRT may adversely influence the outcome of these tumours, al though this is theoretically possible since the effect of estrogens on occult metastases is unknown. The relationship between replacement therapy and the uterine sarcomas is of particular concern. HRT is safe in patients successfully treated for carcinoma of the vulva, vagina, uterine cervix and in those with ovarian cancer. Experience suggests that estrogen can also be used safely in women treated previously for endometrial cancer. As far as breast cancer is concerned, it appers logical to discuss the risk-benefit considerations with our patients before embarking on using HRT. Consultation with a gynaecological oncologist prior to HRT in patients with endometrial and/or breast cancer is strongly recommended. ]

[Developing a complex approach to hospice and home-care]


[The home-care and hospice movement has been sporadically encountered in the hospital and care network for a long time, and we have already seen all that this paper aims to do. Across the country, hospitals and specialist outpatient departments alike are seeking ways and means of providing this care. ]

[The increasing threat of antibiotic resistance: implications for antibiotic prescribing in community practice]

ROBERT Sutherland

[Infectious diseases caused by bacteria have been treated successfully by antibiotic the rapy for the past half century, and a diversity of antibacterial agents with widely differing mechanisms of action has been developed by the pharmaceutical industry. However the selective pressure of antibiotic usage has inevitably led to the isolation of resistant bacteria and the rate of emergence of antibiotic resistance appears to be increasing rapidly, reducing the effectiveness of existing agents. Factors responsible for the wide dissemination of antibioticresistant bacteria in both community and hospital practice include the acquisition and spread of resistant genes by plasmids and transposons, inappropriate anti biotic usage and social factors. Mechanisms to controll the emergence of antibiotic resistance require optimal usage of antibiotics by clinicians, control programmes to improve hygiene and to reduce the transmission of resistant bacteria within and between communities, and the continued development of new antibacterial agents.]

[Highly located and intrahepatic malignant biliary stenoses treated by interventional radiological procedures]

KÓNYA András, VIGVÁRY Zoltán

[In the palliative treatment for patients with highly located and/or intrahepatic malignant biliary stenoses or obstructions interventional radiological procedures may play a significant part. In 12 patients with obstructive jaundice caused by highly located malignant stenosi(es) or obstruction(s) 23 endoprostheses were implanted. In 5 cases double endoprosthesis placement was performed to connect isolated lobes or segments of the liver. Patients' survival was 4–22 (average 8, 7) months. In 6/12 patients surviving for 4-8 months, occlusion of the endoprostheses did not occur. In the other half of the patients, in whom the disease permitted a longer life-expectancy, prosthesis occlusion led to recurrent jaundice within 3–11 months. In all but one case, in which endoscopic exchange was successful, percutaneous interventions were necessary. Successful endoprosthesis placement was carried out 3 times in one patient and once each another 5 patients following percu taneous extraction (3 times), distal displacement (twice) and endoscopic removal (twice) of the occluded endoprostheses. Authors consider percutaneous endoprosthesis placement an effective procedure in the palliative treatment of the aforementioned patients' group, both for improving their survival and quality of life. They emphasize the fact that lengthy and difficult manipulations are required for these procedures which consequently result in a considerable amount of scattered radiation exposure to those performing the procedures.]

[Relationship between ventricular arrhythmias left ventricular dysfunction and late potential after myocardial infarction and during follow up]


[The prognostic significance of post myocardial infarction dysrhythmias and left ventricular dysfunction is well established. We studied the role of late potentials to predict these two abnormalities. A prospective study of the relationship between signal averaged electrocardiogram, left ventricular function and 24 hour Holter ECG monitoring was performed in 39 patients 16,3 + 17,7 days and 16,3 +8,9 months after myocardial infarction. The late potentials were determined by the following parameters: duration of the high-frequency and low amplitude signals (HFLA), voltage in the terminal 40 ms (RMS) and duration of filtered QRS waves (QRS). The left ventricular function was measured by 2D-echocardiography and the rhythm disturbances were detected by Holter ECG monitoring or by our self-developed on-line arrhythmia monitoring. No difference was noted in age (63 versus 58 years, NS), and in the three late potential parameters (HFLA: 34 versus 34 ms, NS; RMS: 43 versus 38 uv, NS; QRS: 109 versus 114 ms, NS) between the groups of patients with normal( 1 group: EF > 40%) and abnormal (2nd group: EF < 40%) left ventricular function. There was a significant difference in all three late potential parameters between the two groups of patients (A. and B. groups) based on the appearance of ventricular rhythm abnormalities (HFLA: 43 versus 31 ms, p<0,01; RMS: 24 versus 47 uv,p<0,05; QRS: 121 versus 106 ms, p<0,01). High resolution electrocardiography may be of prognostic value in selecting a high risk subset of patients (ventricular arrhythmias, sudden death) after myocardial infarction. ]

Single-hole, ruptured parenchymal arteriovenous fistula of the mesencephalon: not known vascular malformation of the brain or a posthemorrhagic entity?

KULCSÁR Zsolt, MACHI Paolo, VARGAS Isabel Maria, SCHALLER Karl, LOVBLAD Olof Karl

The subtypes of brain arteriovenous malformations, with direct, single-hole fistulas without co-existing nidus are not described as existing entities inside the brain parenchyma but on the pial surface. True parenchymal arteriovenous malformations present with nidal structure, even if they are small, whereas surface lesions may present a direct fistulous configuration. In this case of midbrain haemorrhage a direct arteriovenous fistula was detected at the level of the red nucleus between a paramedian midbrain perforator artery and a paramedian parenchymal vein, with pseudo-aneurysm formation at the fistulous connection, without signs of adjacent nidus structure. The hypothesis whether a pre-existing arteriovenous fistula ruptured or a spontaneous haemorrhage has caused the fistulous connection is discussed.

Four cases of GABAB receptor encephalitis

SZŐTS Mónika, MORTEN Blaabjerg, KONDZIELLA Daniel, DIÓSZEGHY Péter, BAJZIK Gábor, BERKI Tímea, KÁLMÁN Endre, NAGY Ferenc, ILLÉS Zsolt

GABAB receptor (gamma-aminobutyric acid type B receptors - GABABR) encephalitis is a rare manifestation of autoimmune encephalitides. We report four cases - including the first two Hungarian patients - with some peculiar features. One patient developed subacute disorientation and almost complete loss of short-term memory, but no epilepsy. Without immunotherapy, his memory spontaneously improved up to mild cognitive impairment in six weeks. GABABR antibodies persisted in his serum, and 18 months later, FDG-PET detected abnormal mediastinal lymph nodes and small cell lung cancer (SCLC). Another patient had persistently decreased sodium content in the peripheral blood. In those three patients who died, CSF was abnormal, but CSF was not pathological in the patient, who spontaneously improved. Brain MRI indicated signal intensity changes in the medial temporal areas in three cases. SCLC was found in three patients. Only the patient, who spontaneously improved, survived for more than 24 months. In summary, our cases show that (i) GABABR encephalitis may develop without epilepsy; (ii) the severe short-term memory loss can spontaneously improve; (iii) persistent hyponatremia can be present in the blood; (iv) the patient with benign course without epilepsy and CSF abnormality survived; (v) spontaneously remitting encephalitis can precede SCLC by 1.5 year, which emphasizes that repeated search for cancer is of paramount importance even in cases with spontaneous improvement.

[Hereditary hemorrhagic teleangiectasia (HHT, Osler-Rendu-Weber disease) is an autosomal dominantly inherited disorder caused by the mutation of several possible genes and characterized by malformations of the arteriovenous system in multiple organs. The clinical diagnosis is based on the Curaçao criteria ((1) spontaneous, recurrent epistaxis; (2) teleangiectasias in characteristic sites (lips, oral cavity, nose, fingers); (3) visceral lesions (gastrointestinal, pulmonary, cerebral, spinal); (4) affected first degree relative). The aim of this study is to present the first genetically confirmed Hungarian case of hereditary hemorrhagic teleangiectasia with multiple ischemic strokes. Our 70-year-old woman has been suffering from severe epistaxis since her childhood and presented gastrointestinal bleeding during her adulthood as well. The characteristic skin lesions developed in the 5th decade of life. She was admitted to our department with loss of consciousness and fluctuating speech and swallowing problems. MRI of the brain supplemented with angiography revealed multiple arteriovenous malformations and multiple subacute ischemic lesions. The EEG demonstrated slowing of electric activity in the left frontal lobe. The neuropsychological assessment showed deficits in anterograde memory and executive functions. The diagnostic work-up for other characteristic alterations identified an arteriovenous malformation in the left lung. The genetic analysis demonstrated a heterozygous mutation in the 7th exon of the ENG gene at position 834 resulting in a thymine duplication and an early stop codon by a frame shift. The present case is largely similar to those already described in literature and draws the attention to the importance of multidisciplinary collaboration in the care of HHT patients.]

The role of the insula in the parieto-frontomedial epileptic network. Clues from successful surgical treatment

BALOGH Attila, AIMEN Anwar, KELEMEN Anna, ERÕSS Loránd, FABÓ Dániel

We present a case of MRI negative SMA seizure with the seizure onset zone in the secondary leg area on the superior bank of the Sylvian fissure, localized with multiscale electro-clinical and neuroradiological examinations. The 34-year-old female patient’s intractable epilepsy started at age 14. She had diffuse pain aura in her left leg followed by tonic posturing with fully preserved consciousness suggesting parieto-fronto-medial seizure propagation. Her daily nocturnal SMA seizures became drug-resistant. Multiple 3T MRI images and neuropsychological evaluations were normal. Interictal PET detected a right parietal and insular FDG hypometabolism. The seizure onset zone and the symptomatogenic zone were localized by invasive electrophysiology. The insular deep electrode showed the propagation of ictal activity with an onset in the secondary sensory leg area through the insula to the fronto-medial surface. Eighteen spontaneous seizures, electrical cortical stimulation and cortical mapping confirmed the designated area of the resection, which was later proved macroscopically abnormal during surgery. The histological and immunohistological workup confirmed focal cortical dysplasia (IIb type). Postoperative postprocessing morphometry of the preoperative MRI study confirmed the lesion in the right inferior parietal lobe. The patient remained seizure free after surgery for more than 4 years, and medication free for the last two years. Our results concluded that the insula has a „relay” or „node” function in the parieto-opercular-fronto-medial epileptic network. The insular functional connectivity predisposed frontal propagation of the epileptic activity in the connectome of her epilepsy. The three-way insular structural connectivity has determining function on the seizure propagation.

The evaluation of the relationship between risk factors and prognosis in intracerebral hemorrhage patients

SONGUL Senadim, MURAT Cabalar, VILDAN Yayla, ANIL Bulut

Objective - Patients were assessed in terms of risk factors, hematoma size and localization, the effects of spontaneous intracerebral hemorrhage (ICH) on mortality and morbidity, and post-stroke depression. Materials and methods - The present study evaluated the demographic data, risk factors, and neurological examinations of 216 ICH patients. The diagnosis, volume, localization, and ventricular extension of the hematomas were determined using computed tomography scans. The mortality rate through the first 30 days was evaluated using ICH score and ICH grading scale. The Modified Rankin Scale (mRS) was used to determine the dependency status and functional recovery of each patient, and the Hamilton Depression Rating Scale was administered to assess the psychosocial status of each patient. Results - The mean age of the patients was 65.3±14.5 years. The most common locations of the ICH lesions were as follows: lobar (28.3%), thalamus (26.4%), basal ganglia (24.0%), cerebellum (13.9%), and brainstem (7.4%). The average hematoma volume was 15.8±23.8 cm3; a ventricular extension of the hemorrhage developed in 34.4% of the patients, a midline shift in 28.7%, and perihematomal edema, as the most frequently occurring complication, in 27.8%. Over the 6-month follow-up period, 57.9% of patients showed a poor prognosis (mRS: ≥3), while 42.1% showed a good prognosis (mRS: <3). The mortality rate over the first 30 days was significantly higher in patients with a low Glasgow Coma Scale (GCS) score at admission, a large hematoma volume, and ventricular extension of the hemorrhage (p=0.0001). In the poor prognosis group, the presence of moderate depression (39.13%) was significantly higher than in the good prognosis group (p=0.0001). Conclusion - Determination and evaluation of the factors that could influence the prognosis and mortality of patients with ICH is crucial for the achievement of more effective patient management and improved quality of life.
