Background/aims: The onset of multiple sclerosis (MS) in Greece has not been systematically studied. We sought to provide data on the onset of MS in Greece with detailed information regarding initial symptoms, and to confirm the prognostic significance of demographic and clinical factors at onset.

Methods: We studied 1,034 consecutive patients with MS and independently assessed 265 patients 'seen at onset'.

Subacute thyroiditis is a painful, inflammatory disease of the thyroid gland, probably of viral origin. It is an uncommon but important cause of fever of unknown origin (FUO). We report a case of a 72-year-old man who presented with a 1 month history of fever, headache and weakness, and in whom extensive evaluation only revealed subacute thyroiditis.

Superficial siderosis (SS), as a result of chronic subarachnoid haemorrhage and haemosiderin deposition on the leptomeninges and subpial layers of the brain, cerebellum and spinal cord, can cause ataxia, pyramidal tract lesions and hearing deficits. In cases with not pronounced hearing impairment adult-onset spinocerebellar ataxia can be considered as a differential diagnostic alternative. We report a similar case where the diagnosis of SS was established by means of gradient echo MRI sequences 5 years after symptom onset.

In cirrhotic patients, in addition to hepatocytes and Kuppfer cells dysfunction circulatory anatomic shunt and ventilation/perfusion (V(A)/ Q) ratio abnormalities can induce decrease in partial pressure of oxygen in arterial blood (PaO(2)), in oxygen saturation of hemoglobin (SaO(2)) as well as various acid-base disturbances. We studied 49 cases of liver cirrhosis (LC) with ascites compared to 50 normal controls. Causes were: posthepatic 37 (75.

Persistent undiagnosed fever remains a common problem in clinical practice. In a variable number of cases, no definitive diagnosis is made. This lack of a clear etiology indicates that certain disorders are not being detected despite the recently developed technology usually applied in this situation.

Splenic abscess is an unusual condition, most often seen in immunocompromised patients. Splenic abscesses are due to aerobic and anaerobic bacteria, fungi and parasites, Staphylococcus aureus being the most common aetiological agent. We describe a case of splenic abscess in an alcoholic patient due to Staphylococcus lentus, a rare aetiology included in the microbiology of this disease.

In the recent past, pathological gambling has been increasingly reported to be related with dopamine agonist application in patients with Parkinson's disease. We present the case of a female patient whose gambling behavior occurred shortly after reaching the final dose of a combined levodopa and pramipexole therapy and resolved completely after stopping pramipexole. Pathological gambling seems to be a rare and serious but reversible adverse reaction to treatment with dopamine agonists of which clinicians should be aware in patients with Parkinson's disease.

Hypertension is probably the most important public health problem in developed countries. Over the last 40 years, an increasing number of hypertensive patients have been treated with various antihypertensive drugs. If the blood pressure (BP) is controlled, the discontinuation of the antihypertensive drug may result either in a relapse of the disease or in the maintenance of normal BP for a long time.

The purpose of this study is to present the 20-year outcome of 206 Charnley low-friction arthroplasties done by the same surgeon on 181 patients who were separated into two age groups (younger and older). In Group A (76 patients, 92 hips) the mean age at surgery was 44 years (range, 24-55 years), and in Group B (105 patients, 114 hips) the mean age at surgery was 65 years (range, 56-82 years). All patients were evaluated clinically and radiographically.

In this study, a review of the available information concerning abrupt withdrawal of antihypertensive drug therapy is presented. Abrupt withdrawal of these drugs can produce a syndrome of sympathetic overactivity that includes nervousness, tachycardia, headache, agitation and nausea 36-72 h after cessation of the drug. A withdrawal syndrome may occur after discontinuation of almost all types of antihypertensive drugs, but mostly occurs with clonidine, beta-blockers, methyldopa and guanabenz.

In the present review article, the penetration of antimicrobial agents into prostatic fluid and tissue was examined. Three major factors determining the diffusion and concentration of antimicrobial agents in prostatic fluid and tissue are the lipid solubility, dissociation constant (pKa) and protein binding. The normal pH of human prostatic fluid is 6.

Fractures of the medial and lateral malleoli are frequently associated with fractures of the posterior malleolus, comprising trimalleolar fractures. The posterior fragment may be posteromedial or posterolateral and its size determines the necessity for surgical or non-surgical treatment. The authors describe a case of trimalleolar fracture with double involvement of the posterior malleolus, both a posteromedial and posterolateral fragment.
