Mono- or Polypharmacotherapy in Institutionalized Epileptic Children with Severe Mental Retardation?

ABSTRACT. Nine severely mentally retarded patients with severe epilepsy who were living in an institution were studied during a three-year period by a multi-disciplinary team. A seizure rate serum level chart was made for each patient. It served as the basis for monthly discussions in the team about medication changes. Drug plasma concentrations were monitored monthly. Statistical comparisons between seizure frequency on different drug regimens were made by χ² test. Withdrawal of all medication was possible in one case and reduction to monotherapy in two cases. In the remainder of the patients a combination of two or three anticonvulsants gave the best clinical effect. We thus found polypharmacotherapy necessary for some severely retarded patients with epilepsy. Our multidisciplinary approach and chart monitoring system has many advantages and is valuable for the medical care and drug treatment of this patient category.     

Various types of suprameatal spines and depressions in the human temporal bone

Since it covers the lateral wall of the mastoid air system, the suprameatal triangle is of importance to otologic surgeons during mastoidectomy. Because of this clinical importance, topographic anatomy of the suprameatal spine and depression was studied on Anatolian skulls. In all, 363 male and 231 female skulls were studied. The most prevalent type of suprameatal spine resembled a crest and was found in both sexes on the right (77.6%) and left (80%) sides. The absence of a suprameatal depression was significantly higher in females (right 9.1%; left 8.7%) than in males (right 1.7%; left 2.5%). Suprameatal depressions were mostly shallow in female subjects, but were mostly observed in males to be at a medium depth or deep. Received: 5 January 1998 / Accepted: 19 March 1998     

Microsomatoagnosia: whole body schema illusion as part of an epileptic aura

We report a patient who presented with a whole body microsomatoagnosia as part of an epileptic aura. We postulate that this rare phenomenon argues in favor of the existence of a whole body integrative neuronal network which mediates the bodily awareness.     

67Ga心肌炎症显像对小儿病毒性心肌炎的诊断价值

目的 :探讨6 7Ga心肌显像对小儿病毒性心肌炎 (VMC)诊断的临床价值。方法 :静脉注射6 7Ga 枸橼酸盐 ,48h、72h后开始显像 ,观察心脏部位放射性浓聚情况 ,并计算心 /肺 (H/L)指数 ,根据H/L指数判断心肌炎性病变的严重程度 (H/L指数 >1.2为阳性 )。结果 :78例病毒性心肌炎患儿中 ,50例阳性 (占 64% ) ,其中急性期阳性率为 84% ,恢复期阳性率为 50 % ,慢性期为 2 9% ,急性期阳性率明显高于恢复期和慢性期 (P<0 .0 5)。结论 :心肌6 7Ga放射性浓聚与心肌炎病变程度呈正相关 ,直接反映了病变心肌的炎症反应情况 ,对诊断VMC有较高的临床价值 ,并对VMC治疗、预后有指导作用     

抗癫痫药物不良反应的针灸治疗

Epilepsy after operative treatment of ruptured cerebral aneurysms

Summary A retrospective analysis of 183 consecutive patients operated on for ruptured cerebral aneurysms and surviving at least one year revealed appearance of postoperative epilepsy in 14 cases (8 per cent) on an average of 10 months (range 0–23 months) after the operation. Factors associated with the development of secondary epilepsy were localization of the aneurysm on the middle cerebral artery, temporary clipping intraoperatively, wrapping technique to treat the aneurysm, and vasospasm seen on the postoperative control angiogram. Intraoperative and/or postoperative ischaemia seems to be the crucial phenomenon favouring the development of epilepsy. Identification of the risk factors may help to focus the anti-epileptic prophylaxis in cases prone to develop seizures.     

Relationship between apoptosis and proliferation in secondary tumors of the brain

A correlation between apoptosis and proliferation in astrocytomas and oligodendrogliomas, but not in glioblastomas, has been previously reported. An index for apoptosis and proliferation was established for each tumor in a series of 20 brain metastases, and its correlation was studied using the Spearman rank correlation test. Apoptosis index (AI) ranged between 1 and 78% (mean ± SD: 11.48 ± 16.4). Proliferation index (PI) ranged between 2.4 and 21% (mean ± SD: 8.23 ± 4.8). When the relationship between AI and PI was studied, a clear correlation was found (r: 0.8965, 95% CI: 0.74–0.95; P < 0.0001). Therefore, it is concluded that a clear correlation exists between proliferation and apoptosis in secondary tumors of the brain.     

Transient Facial Palsy in Sphenoidal Electrode Placement

Summary: Purpose: Sphenoidal electrode (SE) insertion can cause pain, for which local anesthesia with lidocaine or intravenous administration of fentanyl has been advocated by different epilepsy treatment centers. Transient facial palsies have been observed after SE insertion. Their frequency of occurrence, distribution, and duration have not been well characterized, however. We hypothesized that this complication is due to the effect of local anesthesia on the peripheral branches of the seventh cranial nerve. To test this hypothesis, we compared the incidence and characteristics of facial palsy during SE insertions performed with either local anesthesia or after intravenous fentanyl administration.
Methods: We performed a retrospective study in two patient groups. Group A consisted of 25 patients aged 28 ± 8·2 years who underwent a prolonged video-EEG (VEEG) monitoring study with SE after subcutaneous infusion of 1% lidocaine in the insertion area. Group B included 25 patients aged 30·1 ± 8·9 years whose SE were inserted after intravenous administration of 100-200 μ fentanyl. Blood pressure (BP) was monitored every 3-5 min throughout the procedure.
Results: Five patients (20%) from group A had a transient facial palsy; in 4, it was complete and in 1 it was partial; 1 patient had a bilateral facial palsy. Paresis lasted 1-7 min (mean 3·2 min). In all patients, the recovery was complete. None of the patients in group B had complications (p = 0·025, Fisher's exact test).
Conclusions: Transient facial palsy is a relatively frequent complication of SE insertion when SE are placed under local anesthesia; patients should be forewarned of its possible occurrence.     

Nonepileptic Posttraumatic Seizures

Summary: Purpose: Epileptic posttraumatic seizures (PTSs) are a well-recognized consequence of head injury (HI), but HI and nonepileptic seizures (NESs) have not been related. We describe a significant subset of patients with NESs who had their seizures attributed to HI.
Methods: We reviewed the records of all patients diagnosed with NES at the University of Maryland Medical Center over a 6-year period (1989–1995) and selected patients with seizures attributed to a head injury occurring ≥3 years before the onset of their seizures.
Results: Of 157 patients with video-EEG confirmed NES, 37 (24%) had the onset of their seizures attributed to an HI. Their average age was 34 years (range, 15–56 years); 68% were women. Nonepileptic PTS usually developed within the first year after HI (89%). Convulsive symptoms were present in 54%. Whereas epileptic PTSs characteristically follow severe HI, the majority (78%) of our patients with nonepileptic PTSs sustained only mild HI. Before their HI, 76% of our patients were employed, working in the home, or students, but only 11% could continue those activities after developing nonepileptic PTSs.
Conclusions: Nonepileptic PTSs are frequently mistaken for epileptic PTSs and result in serious disability. The misdiagnosis of nonepileptic PTSs leads to ineffective and inappropriate treatment. Patients with intractable seizures after HIS, articularly mild HIS, should be carefully evaluated for NESs.     

Langerhans cell histiocytosis in monocygote twins: case reports

Langerhans cell histiocytosis includes three clinical forms of histocytosis X. We describe a disseminated form of Langerhans cell histiocytosis (Letterer-Siwe disease) in monozygotic twins. The twins showed simultaneous onset of disease, almost identical clinical follow-up and findings on cranial CT. The cause of this phenomenon remains unknown.
