Abstract
We performed topographic EEG investigation with instant voltage mapping in 57 patients with a Rolandic spike focus including 35 patients with benign Rolandic epilepsy. A pronounced maximal negativity of "Rolandic" spikes could be demonstrated over central or mid-temporal electrodes, with a spread to parietal or upper frontal areas with a dipole formation (centrotemporal negativity, frontal positivity) and involvement of midline. There was a moderate correlation between spike amplitude or duration with spread to adjacent areas. No other focal abnormalities such as focal slowing could be revealed by visual or FFT EEG analysis. During light sleep spike activity was pronounced and often associated with generalized spike wave activity. Thus, a functional disturbance rather than a structural lesion can be assumed.

Abstract
BACKGROUND The purpose of the study was to evaluate the feasibility of increasing dose intensity by a stepwise reduction of the time intervals between chemotherapy cycles in separate patient cohorts with small-cell lung cancer. Patients received up to 6 courses of combination chemotherapy with carboplatin, etoposide, ifosfamide and vincristine followed by support with filgrastim. Dose intensity, incidence, duration and severity of neutropenic fever and infections, objective response to chemotherapy, and safety of filgrastim were determined. PATIENTS AND METHODS 29 patients with small-cell lung cancer (limited disease: 2, extensive disease: 27) were treated with a combination of carboplatin 250 mg/m2 i.v. day 1, ifosfamide 2 g/m2 and etoposide 120 mg/m2 i.v. days 1 and 2, etoposide 120 mg/m2 orally day 3, and vincristine 1.4 mg/m2 day 14. Initially, filgrastim (5 micrograms/kg) was administered subcutaneously from day 7 to 16. With shorter treatment intervals, filgrastim was administered on days 4-16 or 4-14. RESULTS An overall increase in dose intensity by a factor of 1.44 was achieved after reducing the treatment interval from 27 to 17 days. Further reduction to 14 days was not feasible due to persistent thrombocytopenia. Six patients (21%) developed a total of 9 febrile episodes, and 14 patients (48%) had to be withdrawn from the study before the completion of six cycles of chemotherapy. The median duration of infectious episodes was 6 days. Overall, a total of 22 of 27 evaluable patients had an objective response. Longer treatment intervals resulted in a lower probability for objective response (> or = 23 days: 10/14 patients vs. < or = 17 days: 7/7 patients). CONCLUSION Filgrastim allows for the reduction of treatment intervals in patients with small-cell lung cancer and increased dose intensity with acceptable hematologic and nonhematologic toxicities.

Abstract
Three newborn siblings presented with generalized weakness, asphyxia, facial diplegia, and external ophthalmoplegia. Electrophysiological testing showed inexcitability of motor and sensory nerves and myographic signs of denervation. Nerve biopsies and postmortem examination showed loss of myelinated fibers and axonal damage in sensory and mixed nerves. Many spinal motor neurons were chromatolytic although their number was normal. Molecular genetic investigations revealed a homozygous deletion of the survival motor neuron (SMN) gene and a loss of markers Ag1-CA and C212 in the paternal haplotype. These findings are consistent with the diagnosis of an unusually severe type of spinal muscular atrophy. Given the large extent of the deletion, it must be considered that the unusual severe phenotype with involvement of brainstem nuclei and afferent nerves might also be due to changes of yet unknown genes neighboring the SMN gene.

Abstract
A new amidohydrolase deacetylating several N-acetyl-1-phenylethylamine derivatives (R)-specifically was found in Arthrobacter aurescens AcR5b. The strain was isolated from a wet haystack by enrichment culture with (R)-N-acetyl-1-phenylethylamine as the sole carbon source. (R) and (S)-N-acetyl-1-phenylethylamine do not serve as inducers for acylase formation. By improving the growth conditions the enzyme production was increased 47-fold. The amidohydrolase was purified to homogeneity leading to a 5.2-fold increase of the specific activity with a recovery of 67%. A molecular mass of 220 kDa was estimated by gel filtration. Sodium dodecyl sulfate/polyacrylamide gel electrophorosis shows two subunits with molecular masses of 16 kDa and 89 kDa. The optimum pH and temperature were pH 8 and 50 degrees C, respectively. The enzyme was stable in the range of pH 7-9 and at temperatures up to 30 degrees C. The enzyme activity was inhibited by Cu2+, Co2+, Ni2+, and Zn2+, and this inhibition was reversed by EDTA.M.

Abstract
Previous studies have indicated that scores on the Developmental Test of Visual Motor Integration correlate higher with Performance than Verbal and Full Scale IQs of the Wechsler Intelligence Scale for Children-Revised. WISC-III and Visual Motor Integration-3R scores from 99 boys and 46 girls ranging in age from 6 to 16 years were obtained by certified school psychologists to study the relationship between the two measures. Participants were drawn from six suburban Chicago school districts, two being very affluent. These Pearson correlations for standard scores ranging from .34 to .57 and following previous research, were ranked from highest to lowest and then transformed into an approximately normal Z statistic using Fisher Z. The highest correlation was compared to the next highest and so on, which yielded significant differences. Only four comparisons had to be made.

Abstract
PURPOSE We studied the functional organization of the interictal epileptic spike complex in patients with benign rolandic epilepsy of childhood (BREC). METHODS We recorded interictal epileptiform spikes and somatosensory evoked potentials after median nerve stimulation, providing a biologic marker for the location of the central sulcus in 12 patients with BREC. We used multiple dipole modeling to assess the number, the three-dimensional intracerebral location, and the time activity of the underlying neuronal sources. RESULTS Although the interictal spike complex could be modeled by a single tangential dipolar source in seven patients (group 1), in the remaining five patients, two sources-a radial and a tangential dipole-were necessary adequately to explain the interictal spikes (group 2). The tangential source was located deeper than the radial source and was characterized by a frontal positivity and a centroparietal negativity with a phase reversal across the central sulcus, suggesting that the interictal spikes originated in the anterior wall of the central sulcus. The radial source showed a single electronegativity over the ipsilateral central region, which would be compatible with involvement of the top of either the pre- or postcentral gyrus. Both sources showed biphasic time patterns with an average latency difference of 30 ms. CONCLUSIONS Our results indicate that in some patients with typical BREC, the interictal epileptiform spike complex is generated by multiple, simultaneously active neuronal populations within the central region and that epileptiform activity is propagated between these two adjacent cortical areas.

Abstract
HISTORY AND CLINICAL FINDINGS A 66-year-old woman was known to have had cholecystolithiasis for at least 4 years. Laparoscopic cholecystectomy was performed at another hospital where histological examination surprisingly revealed middle-grade differentiated carcinoma of the gall-bladder (pT2, G2). A nodular metastasis of the gall-bladder carcinoma was noted on the abdominal wall 3 months later and excised. Lymph-vessel carcinomatosis was already present. The patient again noticed a tumour in the right mid-abdomen and a further tumour was palpated in the epigastrium 5 months after the operation. INVESTIGATIONS Laboratory and tumour-marker (CEA, CA 19-9) tests were unremarkable, while sonography and computed tomography were highly suspicious for abdominal wall metastases in the epigastrium and right mid-abdomen. TREATMENT AND COURSE Both metastases were excised. Laparotomy revealed tumour recurrence in the old gall-bladder bed, as well as extensive peritoneal carcinoma. Two months after the operation she developed jaundice, caused by tumour compression of the choledochal duct. An expanding stent was inserted into the stenosed section of the duct. The patient died 13 months after the first operation from the underlying malignancy with multiple liver metastases and malignant ascites. CONCLUSIONS Indications for minimally invasive surgery in malignant tumour should be narrowly defined. Because tumour seeding is possible after laparoscopic cholecystectomy with incidentally found carcinoma extensive re-excision should be performed.

Abstract
We analyzed the adequacy of pain control for 17 trauma patients during the initial part of their stay in the intensive care unit, and assessed reasons for inadequate analgesia, if it occurred. Patients, and physicians, and nurses were interviewed. A verbal pain intensity scale was used to determine whether patients received adequate analgesia. Patients were asked if the pain hindered their activities, and whether they requested pain medication from their caregivers. Caregivers were questioned whether patients received adequate analgesia. Prescribed morphine regimens and the amount of narcotic administered were analyzed. Twenty-seven percent of patients rated pain intensity as moderate and 47% as severe. Ninety-five percent of housestaff and 81% of nurses reported the patients received adequate pain control. Forty-seven percent of the patients who had moderate or severe pain asked their physician for more pain medication, and 65% asked the nurse. Thirteen residents did not order a larger dose of morphine due to concern about respiratory depression or hypotension. Morphine dosages ranged from 1-8 mg intravenously every 1-2 hours as necessary. Nurses administered less than the maximum amount ordered 58% of the time. The mean dosing interval was 2.3 hours. Barriers to adequate pain management were disparity in the perception of pain between patients and caregivers; patients not requesting more analgesia despite despite the presence of moderate to severe pain; and physician and nurse concerns about patients' adverse physiologic response to increased dosages.

Abstract
To investigate the need for hormonal treatment in patients with functional ovarian cysts (FOC), the efficacy of this treatment was evaluated in a retrospective and also in a randomised prospective study. By retrospective analyses the resolution of FOC with a mean diameter larger than 2.0 cm at the beginning of a cycle was determined in 113 patients (31.6 +/- 4.6 years). Fifty-seven women received an oral contraceptive (ethinylestradiol 50 micrograms/d for 7 days, ethinylestradiol 50 micrograms and desogestrel 125 micrograms/d for 15 days), the others had no therapy. In a second study 59 patients (32.3 +/- 4.6 years) were randomised to receive a combination of ethinylestradiol 50 micrograms and levonorgestrel 250 micrograms/d for 21 days (Group 1, n = 24), or lynestrenol 10 mg/d continuously (Group 2, n = 14) or a third group (Group 3, n = 21) without treatment. In both studies no differences were found between those patients who had hormonal treatment and those who had not. The prospective study revealed that spontaneously appearing FOC and FOC evolving after ovulation induction during the cycle prior to study enrolment, resolved equally well within 12 weeks independent of contraceptive or gestagen treatment. FOC persisted in only one woman (group 2) who had a surgically proven endometrioma. In conclusion, hormonal treatment does not produce regression of FOC in women of reproductive age.

Abstract
PURPOSE To evaluate the hemodynamics and tissue response associated with stent placement in low-flow-velocity arteries. METHODS Six self-expanding nitinol stents (5.5 mm caliber) were implanted transfemorally within the proximal segments of vertebral arteries (2.5 mm diameter) in six adult dogs during anticoagulative protection. RESULTS Control angiograms demonstrated patency and 20% dilatation of all stented arteries. One artery was partially thrombosed 1 week later and subsequently showed a 50% stenosis. Throughout the observation period (4 to 9 months after stenting), the other five arteries remained patent without significant narrowing (< or = 15%). Small cervical muscle branches originating from the vertebral arteries within the stented segments remained patent. No major branch occlusions of the vertebrobasilar system were detected. Stent migration or kinking did not occur. MR studies of the brain 4 months after implantation revealed no infarcted areas. These findings were confirmed with brain sections. Stented artery specimens showed delayed stent dilatation. A comparison of the total mean thickness of intima covering the five 30- to 40-mm stents removed at 4, 6, and 9 months showed no significant difference (338, 332, and 389 microns, respectively). Histologic findings verified the macroscopic impression of a thicker intima at the inner curve of the stented artery segments and at the junctions of the stent filaments. The shortest (10 mm) stent had the thinnest neointimal growth (155 microns). Stented vessels showed compression of the media with atrophy, but without necrosis or perforation. Scanning electron photomicrographs revealed intact endothelial cell linings with typical elongated cells. CONCLUSIONS No significant risk of thromboembolic events exists after implanting these nitinol stents in nonatherosclerotic vertebral arteries in dogs. Thicker neointimal growth after stenting may result from either low wall shear stress with possible flow separation or from changes in the shape and size of the stent, or both.

Abstract
Surgery for carcinoma of the esophagus and cardia represents potentially curative therapy in early stage of tumor. In the advanced stage of tumor palliation is the only remaining therapeutic aim. In a retrospective study covering the period 1984-1992 we analyzed 51 patients who underwent surgery for esophageal or cardia cancer to determine whether palliation by surgery is feasible. We also analyzed morbidity and mortality of peri- and postoperative complications. In 88% we carried out standard esophagectomy consisting of abdomino-thoracic access, gastric interposition with thoracic anastomosis and extramucous pyloromyotomy. In the light of postresection histology, 53% of the operations were potentially curative (UICC stage I and II) [1], 47% palliative (UICC stage III and IV) [1]. Perioperative 30-days mortality was nil, perioperative 30-days morbidity 11% (3 patients developed pneumonia postoperatively, 2 patients with cervical anastomosis developed dehiscence of anastomosis which in both cases healed completely with conservative therapy, while a further patient with cervical anastomosis suffered persistent paralysis of the recurrent nerve. All patients were fully able to feed themselves at the time of discharge. 43% of patients had recurrent dysphagia and 24% underwent endoscopic dilatation. Three-year survival was 26%. From these results it may be concluded that esophageal resection represents either good palliation with low morbidity for the majority of patients with non-resectable carcinoma of the esophagus or potentially curative therapy with low morbidity in early stage of tumor.

Abstract
The effect of intercurrent brain lesions on the characteristics of chronic epilepsies has not yet been the subject of detailed investigation. We therefore retrospectively examined this issue for idiopathic, cryptogenic as well as symptomatic chronic epilepsies in patients documented in routine investigations at our outpatient seizure unit between the occurrence of epilepsy and commencement of the study. The clinical criteria for inclusion in this study were brain injury by trauma, stroke or intracerebral hemorrhage, documented by CT scan, and the occurrence of this so-called index event in patients with established chronic epilepsy. These requirements were met by 63 patients (40 male, mean age 44.8 years, SD 14.7 a; 23 female, mean age 43.1 years, SD 16.4 a). Seizure characteristics, EEG recordings as well as seizure frequencies before and after the index event were compared. Patients and controls were observed for a mean time of 22.12 years (SD 7.33 a) and 22.01 years (SD 11.31 a), respectively. Two patients presenting with generalized seizures prior to brain injury underwent a change in seizure characteristics. One control (without intercurrent brain lesion; matched for age, sex, age at onset of seizure disorder and classification of seizure disorder) primarily presenting with partial seizures evolving to generalized seizures showed changed seizure characteristics. These changes are statistically insignificant (McNemar test for the significance of changes). Seizure frequencies decreased significantly after brain injury. EEG recordings mirrored clinical findings with additional focal aspects according to brain lesion. These findings are discussed mainly with respect to the cofactorial etiology of epilepsies.(ABSTRACT TRUNCATED AT 250 WORDS)
