Lege Artis Medicinae - 1992;2(06)

[The process of inflammation can be classified as acute, subacute and chronic, as well as the special category of granulomatous inflammation. Classification of granulomatous inflammation based on morphologic criteria. These are epitheloid, histiocytic, foreign-body, necrobiotic and mixed inflammatory granuloma. The current knowledge suggests the following sequences for the mechanisms of granuloma formation in sarcoidosis (Fig 2): 1. T-cells are locally activated and proliferating 2. These activated T-cells release lymphokines that recruit and activate monocytes/macrophages 3. These activated monocytes/macrophages may differentiate into granuloma cells such as epithelioids cells and multinucleated giant cells and release pro-inflammatory profibrotic mediators that modulate the granulomatous and fibrotic process. It is hoped that further studies in sarcoidosis will help not only in clarifying the pathogenic mechanisms leading to granuloma formation, but also in eventually revealing the etiology of sarcoidosis. ]

[Transvaginal ultrasound examination of embryo development in early pregnancy (sono-embryology) II. central nervous system]

CSABAY László, SZABÓ István, NÉMET János, PAPP Zoltán

[In the second part of their paper, the authors look over the most important phases of the development of the central nervous system during the first trimester of pregnancy - especially considering the stages, which can be differentiated with a high resolution transvaginal transducer. The closed neural tube is developing at days 40 to 44 by the closure of the posterior neuropore, however at this time no brain structures can be detected by ultrasound. During the 7th week the three primary brain vesicles (prosencephalon, metencepha lon, myelencephalon) can be identified – a single ventricle can be seen by ultrasound. During the 8th week the secondary brain vesicles (telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon) can be separated. During the 9th week the lateral ventricles are filled out by the choroid plexus, which are retracted to the occipital horn by the 13th week. The appearance of the brain structures also takes place according to an accurate „calendar". The structures recognized by ultrasound can be compared to those of the central nervous system known from embryology. The problem of the primary prevention of the cerebrospinal malformations, which are among the most frequent congenital disorders, is not yet solved; therefore the early prenatal diagnosis of the structural anomalies has great importance. ]

[Laparoscopic varicocelectomy]

HOLMAN Endre, TÓTH Csaba, PÁSZTOR Imre, FICSÓR Ervin, PAPP Ferenc

[ With the spreading use of the laparoscope in the urological surgery laparoscopic varicocelectomy may become an alternative treatment of varicocele. The method can be advantageous mainly for patients with bilateral cases compared to the open operation. The authors report on two cases that have been the first urological laparoscopic operations in Hungary.]

[Vascular surgical aspects of small bowel ischaemia]

DÓBI István

[A brief account is given of acute and chronic diseases underlying the disorders of blood supply to the small bowel. In cases of acute disorders, considering the diagnostic difficulties involved, the author stresses the importance of commencing of a vasodilatator treatment immediately after the tentative diagnosis has been reached based on the first suspicious symptomes, and also requiring angiography to render the accurate diagnosis. This is the only possibility to increase (without irreversible tissue damages) the number of successful early vascular reconstructions which are the prerequisites to reducing in lethality. Finally, based on his own extensive experimental work, the author proposes to make allowances for the augmented local postischaemic vasoconstrictor trends of vascular reactivity in the complex therapeutic regimen of these diseases. ]

[Cardiovascular effects of sleep-related breathing disorders, a review]

VÁRDI Visy Katalin

[The acute and chronic cardiovascular effects of sleep related breathing disorders are summarized in this review. Obstructive sleep apnoea syndrome is characterized by recurrent upper airway collapse during inspiration. The resulting asphyxia causes hypoxia and arousal. The vigorous inspiratory efforts produce falls in blood pressure coinciding with each effort (pulsus paradoxus). A rise in blood pressure is seen concurrently with each termination of apnoea and arousal. Bradycardia induced by hypoxia in each obstructive period and increased frequency at time of arousals could lead to arrhythmias. This may result in a high prevalence of hypertension, acute myocardial infarction and arrhythmias in sufferers of obstructive sleep apnoea syndrome have. ]

[Evaluation of one hundered cancer cases in the practice of a general practicioner]

KISS László

[The author, working as a general practicioner in Czecho-Slovakia, gives an analysis of one hundred malignant tumour patients. In 31 cases the tumours have been in favourable position, and it would have been possible to set up early diagnosis in the general practice. The early diagnosis has actually happened only in 15 cases. The tumor has been verified at an advenced stage in 16 cases (2 of them have been inoperable). Delay has occured in two cases because of the nature of the cancer; in one case the general practicioner and in two ones the specialist missed the diagnosis; in the rest of the cases (11) the patient appeared too late. The author expresses that development in early cancer diagnosis is based on effective health education beyond the permanent on cological vigilance. ]

[Myasthenia in a patient with sarcoidosis and schizophrenia (in English language)]

RÓZSA Csilla, KIS Gábor, KOMOLY Sámuel

[A 44-year-old male patient was hospitalised with paranoid schizophrenia in 1985. Depot neuroleptic treatment was started which successfully prevented further psychotic relapses for the next ten years. His myasthenia gravis started with bulbar signs in 1997 and the symptoms soon became generalized. The diagnosis of myasthenia gravis was confirmed by electromyography, by positive anticholinesterase test and by the detection of anti-acetylcholine receptor antibodies in the serum. Mediastinal CT examination showed enlarged hilar lymph nodes on the left but no thymic pathology was observed. Mediastinoscopy was performed and biopsies were obtained from the affected nodes. Histology revealed sarcoidosis. The patient suffered respiratory crisis following the thoracic intervention (in September 1998). Combined oral corticosteroid (64 mg methylprednisolone/e.o.d.) and azathioprine (150 mg/day) treatment regimen was initiated and complete remission took place in both the myasthenic symptoms and the sarcoidosis. The follow-up CT scans showed no mediastinal pathology (January 2000). During steroid treatment a transient psychotic relapse occured which was successfully managed by supplemental haloperidol medication added to his regular depot neuroleptics. The patient currently takes 150 mg/day azathioprine and receives 40 mg/month flupentixol depot im. His physical and mental status are stable and he has been completely symptome free in the last 24 months. The association of myasthenia gravis and sarcoidosis is very rare. To our best knowledge no case has been reported of a patient suffering from myasthenia gravis, sarcoidosis, and schizophrenia at the same time.]

[Sarcoidosis involving liver and spleen, and with hypercalcemia]

TÓTH Mónika, WENINGER Csaba, MORÓ Zsuzsanna, SZOMOR Árpád

[INTRODUCTION - Sarcoidosis is a relatively common multisystemic disorder. Chest involvement is most frequent, but any organ can be involved. In case of abdominal lesions the suspicion of sarcoidosis rarely arises. CASE REPORT - A 53-year old female patient with a history of crural pain unresponsive to medications and weight loss of unknown origin was sent to the internist. Hypercalcemia and bone pain suggested multiple myeloma, however, this diagnosis could not be confirmed. Chest X-ray examination was negative. Splenomegaly and multiple hypodens splenic and hepatic lesions were detected by ultrasound and abdominal computed tomography. Finally, ultrasound guided biopsy of the liver proved stage II sarcoidosis. Steroid therapy was initiated and the splenic and hepatic lesions seen with ultrasound and CT scan disappeared. CONCLUSION - Sarcoidosis is usually suspected following chest X-ray or during chest CT examination. Nevertheless, our case demonstrates that multiple lesions in the spleen or liver may indicate sarcoidosis even in the absence of thoracic lesions. Biopsy taken from the lesions can lead to adequate diagnosis.]

[INTRODUCTION - The histological pattern of sarcoidosis and cytological characteristics are similarly unspecific. Nevertheless, both forms of the diagnosis based on morphology can be taken into consideration if the clinical picture and chest X-ray respectively, are fitted and other diseases are excluded. PATIENTS, METHOD AND RESULTS - Enlargement of hilar lymph nodes is present in 80% of cases of sarcoidosis. In this study, transcarinal needle aspiration combined with rapid on-site cytological staining was performed in the case of 33 patients with I. or II. stage of sarcoidosis. The sensitivity was found to be 76%. CONCLUSION - Since the cytologist can inform the bronchologist fairly soon: during the bronchoscopy, bronchial mucosal biopsies or transbronchial lung biopsies are only necessary to obtain in about quarter of patients.]

[INTRODUCTION - Intramuscular follicular Bcell lymphoma is a rare entity of malignant lymphomas complicating the disease course of dermato/polymyositis. CASE REPORT - The authors report a female patient who was diagnosed with dermatomyositis in 1963 (age of 36). She was given steroid and hydroxychloroquine therapy. In 1973 she was treated with steroid for Boeck sarcoidosis. In 1999, she was treated for steroid therapy again for reoccurence of dermatomyositis. In 2000, a histological diagnosis of primary intramuscular follicular lymphoma was established from the right thigh region. She was given several courses of polychemotherapy and radiation therapy, but the lymphoma was difficult to control, and she died of progressive disease in 2003. CONCLUSION - It is an interesting case as 37 years elapsed since the diagnosis of dermatomyositis before the lymphoma has started. We could not state a definite relation between the myositis and the lymphoma but the increased frequency of autoimmune diseases is probably due to immune regulatory problems, that have eventually led to the appearance of the rapidly growing indolent lymphoma.]
