JUNE 30, 1993

Lege Artis Medicinae - 1993;3(06)

[The distinction between the partial and complete forms of the hydatidi form mole is very important for the risk of a malignant transformation is higher in the latter type. Biopsy samples were studied from 32 hydatidiform moles previously examined clinically and cytogenetically. The purpose was to find out the most important morphological differences between the complete and partial forms of this disease. Comparing with the literature it was established that admixture of normal and hydropic villi, pre sence of fetal elements in the biopsy material focal and moderate proliferation of trophoblastic cells, scalloped outline of the hydropic villi and trophoblastic inclusions in the stroma of the villi could call the attention of the pathologist to the existence of partial mole even in lack of clinical and cytogenetical data. ]

[The role of angiotenzin converting enzyme inhibitors in the treatment of hypertension]

FARSANG Csaba

[The role of the renin-angiotensin system in the regulation of blood pressure is outlined. The mechanism of action as well as the role of angiotensin converting enzyme inhibitors (ACEI) in the treatment of various forms (primary, secondary, uncomplicated, complicated) of hypertension is discussed. The individualized , stepped care" approach is detailed, therefore the advantages of the therapeutic combinations of ACEi-s are emphasized. Interactions with other antihypertensive agents and with other drugs are also described, and side effects are also briefly addressed]

[Postmenopausal hormone replacement therapy]

H S Jacobs, F E Loeffler

[Over the past year, a number of summary publications on postmenopausal hormone replacement therapy have been published in the UK (1-3). Therefore, in this review we focus on areas that, although often controversial, may be of interest to practitioners. We will discuss the effects of postmenopausal hormone therapy on the risk of ischaemic heart disease, osteoporosis and cancer and present some observations on the concept of oestrogen tachifilaxis and dependence. Our conclusions are summarised in our recommendations on hormone therapy in menopause.]

[Immunohistochemistry of atherosclerotic lesions]

ILLYÉS Gyula, KÁDÁR Anna

[Cellular interactions within the arterial wall are considered to be essential in the development and progression of atherosclerotic lesions. This paper is a review of the actual knowledge about the role of the macrophages in the process of atherogenesis. The cellular composition of atherosclerotic changes – aligned in a possible consecutive order in which they may progress – are presented and discussed from the author's own immunohistochemical investigation. 108 aortic specimens obtained at autopsy performed within 12 hours following death from young people (20–34 ages) were examined. The Factor VIII positive endothelial lining was well preserved, no desmin content could be demonstrated. In contrary the presence of vimentin was noted in almost all the cells of the aortic wall. The foam cells reacted with different anti-macrophage antibodies, and most of the non-reacting cells of the different lesions proved to be smooth muscle cells. A considerable part of the intimal cells showed HLA-DR positivity as well. The quantity of the T helper lymphocytes in the lesions did not bear any significance. There was relationship between clinical data and types of (early) atherosclerotic lesions in the aorta. It is suggested, that the atherogenetic process starts in the intima with the appearance of smooth muscle cells and an increase in the lipid content. Thereafter macrophages accumulate and lead to the development of foam cells and at the same time they cause tissue damages leading to further smooth muscle proliferation and to classic atherosclerotic changes within the arterial wall.]

[Studies of left ventricular dysfunction]

MATOS Lajos

[510 patients (39.7%) in the placebo group and 452 patients (35.2%) in the enalapril group died. The reduction in cardiac mortality was mainly due to a reduction in progressive heart failure (placebo: 251, enalapril: 209; risk reduced by 22%). There was no appreciable reduction in mortality from arrhythmias without pump failure. However, fewer patients died or were hospitalised due to worsening of circulatory failure (placebo: 736, enalapril: 613; risk reduction 26%; p<0.001).]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

Possible genotype-phenotype correlations in Niemann-Pick type C patients and miglustat treatment

ÇAKAR Emel Nafiye, ÖNAL Hasan

Niemann-Pick type C is a rare lysosomal storage disease caused by impaired intracellular cholesterol transport. The autosomal recessive disease is caused by mutations in NPC1 or NPC2 genes. Clinical-laboratory features, genotype-phenotype correlation and miglustat treatment response of our patients diagnosed with early infantile Niemann-Pick type C were evaluated. In this article, four Niemann-Pick type C patients diagnosed in the early infantile period are presented. Common features of our patients were hepatomegaly, splenomegaly, cholestasis and retardation in motor development. Patients 1 and 2 are twins, with homozygous mutation c.2776G>A p.(Ala926Thr) in NPC1 gene and severe lung involvement. Lung involvement, which is mostly associated with NPC2 gene mutation in the literature, was severe in our patients and they died early. In patients 3 and 4, there were respectively c.2972del p.(Gln991Argfs*6) mutation in NPC1 gene and c.133C>T p.(Gln45*) homozygous mutation in NPC2 gene. In these two patients, improvement in neurological findings were observed with treatment of miglustat. In our twin patients, severe lung involvement was observed. Two of our four early infantile Niemann-Pick type C patients exhibited neurological gains with miglustat treatment.

Acute effect of sphenopalatine ganglion block with lidocaine in a patient with SUNCT

KOCATÜRK Mehtap, KOCATÜRK Özcan

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing/short-lasting unilateral neuralgiform headache with cranial autonomic features (SUNCT/SUNA) is a rare severe headache. At the time of an attack, it can hinder a patient from eating and requires acute intervention. The sphenopalatine ganglion is an extracranial parasympathetic ganglion with both sensory and autonomic fibers. Sphenopalatine ganglion block has long been used in the treatment of headache, particularly when conventional methods have failed. Here, we present a patient who was resistant to intravenous lidocaine, but responded rapidly to sphenopalatine ganglion block during an acute episode of SUNCT/SUNA.

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.
