We report the electroclinical ictal findings of four epileptic patients with clinically asymptomatic celiac disease (CD). Celiac disease diagnosis was suspected by past history and/or computed tomography (CT) findings in all patients and confirmed by laboratory tests and jejunal biopsy. All patients had paroxysmal visual manifestations and ictal EEG discharges arising from the occipital lobe. Epilepsy evolution was favorable in two patients and severe in 2, regardless of CT evidence of occipital corticosubcortical calcifications in 2 patients. Occipital lobe seizures may be characteristic of the epilepsy related to CD, and epileptic patients with these seizures of unknown etiology should be carefully investigated for malabsorption. If past history and/or laboratory tests suggest gastrointestinal (GI) dysfunction they should also undergo small intestinal biopsy even if they do not have GI tract symptoms.

Vertigo in children is rarer than in adults and the examiner in cases showing these symptoms must rely on the parents' or relatives' observations and details. Besides the equilibrium disorders caused by hereditary malabsorption or lesions in the peripheral or central vestibular structures, e.g. ototoxic drugs, tumours in the brain, meningitis, encephalitis, otitis, labyrinthine fistulas or head trauma, we only known of typical diseases, associated with vertigo, that develop during childhood. These are: so-called benign paroxysmal vertigo of childhood, benign paroxysmal torticollis, basilar migraine, spasmus nutans, visual-cliff phenomenon, and kinetosis. Careful examinations are necessary to differentiate these illnesses from vestibular epilepsy, brain tumours, and hereditary episodic vertigo. Neuro-otologic examination in children, especially small children, is a kind of "stepchild" in ENT departments. The reasons are the time-consuming examination necessary in the case of children and by problems connected with a plethora of troublesome individual tests. Additional difficulties arise in cases of sensory, mental, and other impairments. - The paper gives an overview of vestibular disturbances during childhood and diagnostic procedures for determination by means of Frenzel glasses, electronystagmography, cranio-corpography, and posturography.

The meaning of a low serum cobalamin level when the classic findings of pernicious anemia are lacking is undergoing reevaluation. We therefore studied the neurologic status of 11 patients who had low cobalamin levels without definite hematologic evidence of deficiency. Neurologic evaluation included pattern-shift visual and median and posterior tibial nerve somatosensory evoked potentials. None of the patients had megaloblastic changes in the blood or bone marrow, although 7 of the 11 had subtle cellular cobalamin disturbances demonstrated by an abnormal deoxyuridine suppression test result. Seven patients had normal Schilling test results and 2 had borderline results; however, 2 of the 5 patients tested further had food-cobalamin malabsorption, while a third had prepernicious anemia. The patients displayed a variety of neurologic problems, including dementia, depression, myelopathy, neuropathy, and seizure disorder; 1 patient was neurologically normal by clinical criteria. Evoked potential abnormalities were demonstrable in 8 of the 9 patients with subtle cobalamin deficiency, and in at least 5 cases the disturbance was central. In contrast, both patients whose low serum cobalamin levels were found on evaluation to be spurious had normal evoked potentials. Evoked potential abnormalities improved in the one patient retested after cobalamin therapy. These findings demonstrate that neurologic deficits occur not only in classic cobalamin deficiency but also in subtle or atypical cobalamin deficiency states in which anemia is absent and Schilling test results are normal. Electrophysiologic evidence of neurologic impairment is often present, even in patients without obvious clinical neurologic abnormalities.

Two patients with the syndrome of Ramsay Hunt (dyssynergia cerebellaris myoclonica, DCM), associated with malabsorption due to adult coeliac disease, are reported. Both presented with progressive cerebellar ataxia, action myoclonus, and epilepsy. One had gastrointestinal symptoms (recurrent diarrhea and weight loss which responded satisfactorily to a gluten-free diet), but the other did not. In both patients, jejunal biopsy revealed subtotal villous atrophy; serum folate and vitamin E level were also reduced. Neither a gluten-free diet nor vitamin supplements improved the neurological picture. However, some symptomatic relief was afforded by treatment with clonazepam, sodium valproate, carbamazepine, and piracetam. It could be argued that the association between these two disorders is coincidental. However, since we have found this combination in 2 of 14 consecutive cases with DCM, a causal relationship seems likely, although the underlying mechanism remains unknown. Patients with the Ramsay Hunt syndrome should be investigated for malabsorption, and also undergo small intestinal biopsy.

A review of the literature on the medical and nutritional use of medium-chain triglycerides (MCTs) since 1970 is presented with additional discussions on the various modifications and applications of the MCTs in the synthesis of certain structured lipids. The metabolism of MCTs in the liver and extrahepatic tissues is discussed along with further documentation of the use of MCTs in malabsorption and hyperlipidemia cases. Recent applications of MCTs and modified MCTs in hyperalimentation, deficiency in the carnitine system, epilepsy, obesity, and other special areas of application are cited. The use of medium-chain monodiglycerides for dissolving cholesterol gallstones is presented. The contraindications for the use of MCTs in ketosis, acidosis, and cirrhosis are also discussed. Suggestions for use of MCTs in a variety of medical and nutritional applications are presented.

After the development of monophasic combined oral contraceptives (COCs), containing a fixed dose of estrogen and progestogen, biphasic and triphasic COCs were introduced in the 1980s; in these the dose of ethinyl estradiol and progestogen changes during the pill cycle. In the so-called every day pills, the 21 pills of active steroid combination are followed by 7 inactive pills containing starch, iron, or bran. Method failures of OCs are among the lowest ranging from 0.2-1/100 woman-years. User failures can be as high as 6.2/100 women-years. The individual difference in peak plasma levels of estrogens in women taking identical OCs can be 10-fold. Conditions that affect the bioavailability of contraceptive steroids are: 1) drug interaction (vitamin C, drugs that induce liver enzymes, and antibiotics); 2) vomiting; 3) vegetarianism; 4) missing pills; and 5) malabsorption. Metabolic effects of COCs pertain to carbohydrate metabolism, lipid metabolism, hemostasis, and vitamins. Prescribing of COCs involves counseling clients about contraindications to COCs, starting routines, and the pill-free interval, as well as follow-up and monitoring, the problem of missing pills, and selection criteria for OC use. Medical conditions in which COC use requires special consideration are sickle cell disease, trophoblastic disease, HIV disease, gallstones, epilepsy, valvular heart disease, oligomenorrhea/amenorrhea, inflammatory bowel disease, and surgery. Side effects of COCs may include depression, nausea, vomiting, headaches, urinary tract infection, and lower genital tract infections. 6 months after stopping the OC 1% of users become amenorrheic. Many of the common causes of amenorrhea, such as weight loss amenorrhea and polycystic ovarian disease, may be treated with the COC until the couple desires to have a baby. The new progestogens desogestrel, norgestimate, and gestodene are highly selective compared to first and second generation progestogens.

The authors report on five patients (three female, two male) with multiple brain calcifications, infantile celiac disease, and epilepsy. The clinical, neuroradiological, neurophysiological, EEG and evolutional aspects are assessed. The authors propose that all patients with brain calcifications which cannot be traced to other known pathologies should undergo diagnostic tests for a malabsorption syndrome; analogously, patients affected with infantile celiac disease should undergo EEG, followed by a neuroradiological examination if the EEG pattern is found to be altered.

The association of celiac disease, epilepsy and occipital calcifications with initial clinical manifestations of epilepsy during the first two decades of life with an often progressive and variable course and clinical expression of malabsorption has recently been described. Two cases of celiac disease with occipital calcifications and a presentation with neurologic symptoms in adulthood are reported. The first case is that of a 40-year-old male who presented recurrent and alternating pure brachial monoparesis and later acute abdominal pain following which celiac sprue was diagnosed. The second case is that of a 53-year-old woman diagnosed with celiac sprue 20 years before, presenting permanent myoclonus in the lower limbs which were progressive in severity, ataxic march and generalized tonoclonic seizures. Both patients had bilateral occipital calcifications on CT and celiac disease was demonstrated on biopsy. The first case also showed marked signal alteration in the white matter on MRI. Celiac disease with cerebral calcifications presents also in adulthood with atypical clinical manifestations. Suspicion of celiac disease may be confirmed by non-invasive methods such as antigliadin and antiendomysium antibody determination. CT imaging is characteristic.

Although the association between celiac disease and progressive myoclonic ataxia is well recognized, in each of the reported cases the neurologic features began in middle adult life and usually in patients who had clinical or laboratory evidence of malabsorption. We report a case of progressive myoclonic ataxia and epilepsy (Ramsay Hunt syndrome) that began in childhood. In this patient there were no features suggestive of gluten intolerance. The presence of antigliadin antibodies in the serum and CSF suggested celiac disease was the cause of the patient's neurologic syndrome. Duodenal morphologic abnormalities reversed with treatment but no major changes were noted in the patient. Celiac disease should be considered in the differential diagnosis of myoclonic ataxia at any age, even in the absence of clinical evidence of gluten-sensitive enteropathy.

We have studied four patients (three male, one female, age range 15-25 years) with epilepsy, bilateral occipital calcifications and latent coeliac disease (CD). The epilepsy started at mean age 7 years, in three cases there were partial seizures and in one case generalized seizure. Three cases had symptoms suggesting malabsorptive syndrome during infancy and one case was diagnosed CD before the onset of seizures. In all cases serologic markers of CD were found, especially antiendomisium antibody, and intestinal biopsy indicated several grades of atrophy. The electroencephalograph (EEG) findings pointed to focal abnormalities in three patients and generalized abnormalities in one patient. In all cases computer tomography (CT) showed bilateral, almost symmetrical occipital calcifications in the cortical subcortical layers. The enhanced CT were unremarkable and magnetic resonance images (MRI) were normal. After diagnosis of CD, all patients followed a gluten-free diet and in three patients a significant reduction in seizure frequency was observed. CD should be ruled out in all cases of epilepsy, cerebral calcifications of unexplained origin and malabsorption syndrome in infancy.
