[Topographic distribution of multiple sclerosis in the Belgrade municipalities].

The frequency of multiple sclerosis (MS) varies greatly in different parts of the world, but also within some countries. Many epidemiological surveys of geographical pattern of MS identified areas of different risk of MS in relation to the latitude. The study of disease clusters is a potentially powerful strategy in revealing the aetiology of a disease. A series of space and time clusters of MS has been described over the years, especially in islands' populations. The Belgrade region is located on 628 m height above the sea level, between latitudes 44 and 45 degrees north of the equator, and longitudes 20 and 21 degrees east of the Greenwich. The district of Belgrade is divided into 16 municipalities and extends over an area of 3,222 km2. According to the 1991 census, the area has a population of 1,602,226 inhabitants. All persons who were affected and/or died from MS with residence in Belgrade region had been registered from January 1,1985 to December 31,1996, on the basis of a retrospective analysis of hospital records. The main sources for this study were hospital case records in all 4 neurological hospitals in Belgrade (Institute of Neurology of the Serbian Clinical Centre, which is the primary referral national centre for suspected/diagnosed MS patients in Serbia, and three Departments of Neurology which belong to Zvezdara Clinical Centre, Dr. Dragisha Mishovitsh Clinical Centre, and Military Medical Academy). Only clearly diagnosed and fully documented cases with clinically and laboratory supported MS according to Poser's criteria were included. For each patient, two neurologists (JD and NS) and one epidemiologist (TP) reviewed all data collected in order to verify the validity of the diagnosis. The prevalence, as a number of persons with MS in the population at risk, was calculated on December 31, 1996, for each municipality and for the Belgrade population as a whole. The Belgrade municipalities were categorized according to MS prevalence level, as category 1 (> or = 50/100,000)--Stari Grad, Vrachar, Vozhdovac, Rakovica, Barajevo, Zvezdara; category 2 (30-49/100,000)--Savski Venac, Novi Beograd, Chukarica, Zemun; and category 3 (< 30/100,000)--Palilula, Sopot, Grocka, Obrenovac, Lazarevac and Mladenovac. The geographic distribution was estimated according to the prevalence of MS, and hypothetical cluster of the disease was tested by chi-square test. On December 31, 1996, the prevalence of MS in the Belgrade population was 44.87/100,000. The highest MS prevalence was registered in the municipality of Vrachar (74.63/100,000), and the lowest in the municipality of Mladenovac (17.73/100,000) (Table 1). Municipalities which are grouped within the 3 categories are not statistically significantly clustered (chi-square = 1.479, p > 0.05).

[Cerebrospinal fluid findings in patients with acute and chronic inflammatory demyelinating polyradiculoneuropathies].

We studied the cerebrospinal fluid (CSF) in patients with acute (AIDP) and chronic inflammatory demyelinating poliradiculoneuropathy (CIDP). In order to assess its possible contribution in establishing the diagnostic approach, we analyzed the cell content, concentrations of total proteins, albumin and IgG, CSF/serum albumin quotient and the qualitative study of IgG. Sixteen patients with AIDP and 16 patients with CIDP, fulfilling the accepted diagnostic criteria, were included in this study. CSF features were not used as exclusion criteria. The cell count and concentration of total proteins were determined by standard procedures. CSF albumin was performed and IgG were done by single radial immunodiffusion, and the qualitative analysis of IgG by agarose isoelectric focusing of unconcentrated CSF. The incidence of elevated levels of total CSF proteins was identical in patients with AIDP and CIDP, reaching 94%. The mean level of CSF protein was similar in patients with AIDP and CIDP, 1100 and 1150 mg/l, respectively. The cell count was elevated in 3 (19%) patients with AIDP and normal in patients with CIDP. There were no significant differences in the mean level of any of CSF parameters between patients with AIDP and CIDP. Local synthesis of CSF oligoclonal IgG was found in 2 patients with CIDP and was not detected in patients with AIDP. No association between CSF and clinical parameters was recorded. The results of this study confirm that an elevated CSF protein and low CSF cell count are features highly supportive of the diagnosis of both AIDP and CIDP. The most intriguing finding is the detection of locally produced CSF oligoclonal IgG which may suggest the associated inflammation within the central nervous system in a number of patients with CIDP, and furthermore a pathogenic link between CIDP and multiple sclerosis.

Acute Disease↗

[Dr. John Baptiste Edouard Gélineau].

With this brief review we honor the memory of the great French doctor Jean Baptiste Edouard Gélineau. Dr. Gélineau was born on December 23, 1828 at Blaye, Gironde, close to the Bordeaux region. His name is connected with the first clinical description of the disease for which he, both by the right of the primacy as well as ad valorem of his first two names, coined the name "narcolepsy". He was the first to notice the intrinsically evanescent symptoms of narcolepsy, such as excessive daytime somnolence, imperative sleep habits and cataplexy or "astasia" as he called it, and incorporate them into a single clinical syndrome. In 1881 Gélineau discussed Kaffe's case of "maladie du sommeil" as a proof of the existence of the new disease described a year before. As a good clinical observer Gélineau noticed the close relation of emotional engagement and astasia. His attitude was that narcolepsy was a nosologic entity, a disease sui generis, but admitted that it could appear purely as a symptom only. This was in discordance with the views in England where (in 1928) Dr. Samuel Alexander Kinnier Wilson repudiated such convictions; in 1930 Lhermitte still shared the same opinion. Gélineau differentiated narcolepsy from epilepsy with the elegance of clinical reasoning. Overall, Gélineau described three elements of the narcoleptic pentade. Sleep paralyses were first described by Mitchell in 1876, and were first attributed to narcolepsy by Wilson in 1928; in 1930 Lhermitte first described hypnapompic, and Daniels, in 1934, hypnagogic sleep paralysis. Hypnagogic hallucinations were described by Maury in 1848 and subsequently by de Saint Denis in 1867. In twenties they were thoroughly studiesed during the epidemic encephalitis and after the Big War in 1922 by Levy. The life story of Dr. Gélineau covers multivarious activities. As a young student of the Rochefort Navy Medical School he took part in the fight against colera which deluged the city of La Rochelle. In 1849 he became the "Intern" of the Navy Hospital and next year a "Surgeon of the Third Class". As a Navy surgeon he visited French colonies in the Indian ocean: first the Reunion island and then Mayotte island of the Commores Archipelago. Of this period he wrote "Voyage a i'lle de la Réunion", memoirs published much later, in 1905, in which he described colonial life and abolition of slavery. The story of Elise, a beauteous Creole woman, a concubine of a young naval Commander, who delivered a child that soon died, inexorably points to the autobiographic character of his work. He defended a doctoral thesis "Aperçu Medical de I'lle de Mayotte" at Montpellier University School of Medicine in 1858, using the data collected during his year-and-a-half stay on a Mayotte island; at that time he was a "Navy Surgeon of the Second Class". For his dedication in fighting against epidemics that broke out during the French-German war in 1870 he was nominated for the Legion of Honor, but received it only later. In 1871 Gélineau introduced "Doctor Gélineau's tablets" for the treatment of epilepsy (contained bromide and arsenic). He was a member of the Société de Médicine, Société d' Hypnologie, La-Société Française d' Hygiène, and a few others. After retirement at the age of 72, Gélineau switched to wine production, continuing the family tradition; for the quality of his Bordeaux wines he was awarded gold medals at the Anvers and Paris Exhibitions. Dr. Gélineau died on March 2, 1906, at Argeles Gazost in Pyrnees honored by the titles of Chevalier de la Légion d' Honneur, Officier d'Academie and Commander of Nichan of the Ottoman Empire.

[Dr. John Hughlings Jackson].

The great English neurologist, Dr. John Hughlings Jackson was born in Providence Green, Yorkshire, north England, in 1835. He spent his apprenticeship in the city of York, continued his medical education at St. Bartholomew's hospital in London, and qualified in medicine in 1856. After working in the city of York, he studied in London and in 1860 graduated at St. Andrews university in Scotland. He died in London in 1911, famous and celebrated by his colleagues as the "father of British neurology". Jackson was a prolific writer, witty and ingenious person, but also solitary and absent minded, with a lat of "tiny peculiarities of a genius". At first he was committed to become a philosopher but was persuaded by Jonathan Hutchinson, one of his rare friends, to enter medicine. His "Selected Writings" were first published in 1931 and reprinted recently, in 1996, by Arts & Boeve. Jackson, unlike William Richard Gowers, wrote his articles in a style which was not palatable to his contemporary colleagues. This could be the reason that his medical work was not widely known and would have remained in shadow had it not been rediscovered mostly by German neurologists, who preceded their English colleagues and collected the fame. Jackson gave the first classification of epileptic seizures acceptable, to a degree, even today. It was twofold: the first, taxonomic, which corresponds to contemporary classification of seizures, he compared to the attitude of a gardener who classifies flowers according to their beauty, height or color, and was aware of its purely phenotypic, descriptive and utilitarian character; the second was scientific, physiologic and it would correspond nowadays to the current concept of syndromic classification. Jackson was aware that this 'scientific classification' was to await for the future time, when the knowledge of the real nature of epilepsy became fundamentally broadened. On the other hand, he thought that all the epilepsies were partial becoming generalized only secondarily. Partial epilepsies were the starting point in his work. He realized that epileptic attacks are not different types of epilepsies with different pathophysiological mechanisms, but that they differ in respect to the focus of origin; he stressed their gray matter (cortical) arigin with the cause located as the rule "on the side of the brain, opposite to the body convulsed". Jackson's ideas on epileptogenesis and the localization of epileptogenic processes represent his fundamental contribution to the understanding of their pathophysiology. His most philosophical contribution to neurology was the concept of the evolution and dissolution of the nervous system, which was the consequence of his ideas on its organization. Symptoms observed after the lesion of a certain part of the brain are not the consequence of its function; they are the result of the function of the remaining non-lesioned regions which are in a certain way freed from the adjacent or a higher control. This concept of interpretation af the symptoms of the nervous diseases remains applicable even today. Jackson was the first to stress the importance of ophthalmoscopy in neurology in all cases of neurologic disease, especially in cases of optic neuritis (papilloedema) which may be present even if the patient did not notice the minimized visual acuity. The way of thinking that Jackson introduced in medicine and neurology may be his most precious legacy to the generations that followed.

History, 19th Century↗

[Juvenile myoclonic epilepsy].

CONCLUSION: We conclude that despite inevitable variability the clinical picture of JME is characteristic. It is easy to diagnose JME if one thinks of it while the history should be thoroughly analyzed. An EEG recording during sleep confirms the diagnosis. An early diagnosis of JME permits adequate prognosis of the subsequent course of epilepsy, and adequate therapy brings remission in most of the patients. If treatment starts following the large number of severe GTC seizures, the response to therapy is incomplete. The persistency of the illness throughout the life, the need for continuous medication and therapeutic unresponsiveness in cases with late diagnosis, do not justify the increasing misconception that JME is of benign nature. Diagnosis of JME is rare because of insufficient familiarily of physicians with the illness. BACKGROUND: Juvenile myoclonic epilepsy (JME) is an idiopathic generalized epileptic syndrome characterized with the combination of myoclonic, generalized tonic-clonic (GTC) and absence seizures that are readily provoked by sleep deprivation. PATIENTS: Forty-three patients, aged from 14 to 51 years, participated in a 5-year follow-up study. Diagnosis was made according to the criteria (Table 1) for diagnosis of JME set by Panayiotopoulos et al. (1994). Nineteen patients made their first contact with a neurologist at the Institute of Neurology and were diagnosed as JME, while the remaining 24 were referred to from other medical institutions with a diagnosis of therapy resistant to focal epilepsy. All patients underwent a somatic and neurological examination, "mini mental test," EEG in waking and CT scan of the brain. Some patients had EEG performed during sleep and some had MRI of the head. RESULTS: JME began between 9 and 26 (average 17) years. All patients had myoclonic seizures, 98% had GTC and 23% absence seizures. The first myoclonic seizure occurred between 9 and 24 years while the frst GTC seizure occurred between 10 and 32 years. Myoclonic seizures (83% of patients) and GTC seizures (70% of patients) occurred most often immediately after awaking. The most frequent provocative factors were insufficient sleep, alcohol abuse and tiredness. Epilepsy in the family was present in 39%, focal neurological deficiency in 9% and pathological findings on of CT and MRI in 7% of patients. Waking EEG was pathological in 77% of patients; it included generalized spike-wave discharges in 73%, multiple spike-wave complexes in 33% and focal discharges in 12% of patients, respectively. In all 26 patients tested, sleep EEG was pathological most often with multiple spike-wave complexes in 85% and 3-4 Hz spike-wave complexes in 57% of patients. The correct diagnosis of JME following a comprehensive examination was made in 24 (56%) patients after a delay of 1 to 35 years. In 24 patients with delayed diagnosis of JME the replacement of earlier medication with valproic acid (VPA) induced remission in 18 patients (75%) while 1 patient (4%) experienced a reduction in the number of seizures. Five patients (21%) did not respond to VPA medication: 2 due to a weak compliance, another 2 due to inefficient medication and 1 because of the preexistent malabsorption syndrome. In 19 patients (44%) with initial diagnosis of JME, VPA was introduced immediately upon diagnosis. Of them, 15 (79%) had excellent response to VPA, 1 refused therapy and for 3 patients there is no information. In 2 patients VPA was substituted due to side effects (hepatotoxicity and alopetia) with lamotrigine (low doses), which brought about decrease in frequency and mitigation in myoclonic seizures.
