Komaki H Sugai K Sasaki M Hashimoto T Arai N Takada E Maehara T Shimizu H 《Epilepsia》1999,40(3):365-369
We report a surgically treated case of early infantile epileptic encephalopathy (EIEE) with suppression-bursts associated with focal cortical dysplasia. Tonic-clonic seizures followed by a series of spasms occurred about a hundred times a day at a few days of age. Interictal electroencephalogram (EEG) revealed a suppression-burst pattern that was predominant in the left hemisphere. Magnetic resonance imaging (MRI) suggested focal cortical dysplasia in the left prefrontal area. Combination therapies with antiepileptic treatments showed only partial efficacy. The patient underwent lesionectomy at age 4 months, after which he gradually showed psychomotor development and a decrease of spasms to 0-2 series daily. In cases of EIEE with focal cortical dysplasia, surgical treatment may have beneficial effects on both psychomotor development and seizure control. 相似文献

We present an unusual case of a patient who was diagnosed with temporal lobe epilepsy and whose seizures were reduced markedly after excision of an angiographically occult arteriovenous malformation (AVM) located in the left medial parietal lobe. A 38-year-old man had complex partial seizures characterized by motionless staring with oroalimentary and behavioral automatisms since the age of 15 years. Magnetic resonance imaging (MRI) demonstrated a small lesion extending from the left posterior cingulate gyrus to the precuneus. There was no MRI evidence of mesial temporal sclerosis. Intracranial EEG recordings showed ictal onset from the left medial parietal lobe propagating to the medial temporal lobes. Clinical signs appeared when these discharges reached the temporal lobes. After excision of the lesion (which was histologically confirmed as an AVM), together with the marginal cortex, seizures were reduced significantly. Careful diagnostic evaluation of lesions such as the this one may reveal an epileptogenic lesion (zone) far from the region where scalp ictal discharges seem to arise. In our case, we hypothesize that false localization was due to propagation of ictal discharges from the parietal focus through the limbic system. 相似文献

BACKGROUNDKnowledge of the magnetic resonance imaging (MRI) appearance of the pituitary fossa following transsphenoidal resection of a pituitary adenoma, in the early and late postoperative period, is important for detecting complications and for assessing extent of tumor excision. Few prospective studies have addressed this issue.METHODSFourteen patients with pituitary macroadenomas were prospectively studied with MRI. Maximal tumor resection was accomplished in each patient, and the postoperative histological diagnoses included non-secreting adenoma in 11 patients, prolactinoma in 2 and necrosis in one. Early postoperative scans were obtained within 14 days after surgery, and late studies between 3 and 4 months, in all patients. Four patients also had delayed scans between 8 months and a year. The maximum coronal dimension (MCTD) of the sellar and suprasellar contents was measured on T1-weighted contrast enhanced scans.RESULTSAll patients had normal or improved visual examinations and normal or improved hormonal function postoperatively. The preoperative MCTD ranged from 11 mm to 59 mm in height (mean 30.3 mm). There was little change in MCTD on the early postoperative MRI scans (range 7–49 mm, mean 23.5 mm). However, in all patients the MCTD decreased in height by 4 months (range 2–35 mm, mean 12.7 mm). This change represented a 58% mean reduction in size compared to the preoperative measurements.CONCLUSIONSWe conclude that the appearance of the sellar contents on early postoperative MRI may appear remarkably similar to that seen before surgery, even after technically adequate resection. The postoperative mass may represent a combination of residual tumor, edema, postoperative hemorrhage and hemostatic material. Routine follow-up MRI after transsphenoidal resection of pituitary tumors may be delayed until at least 4 months after surgery in patients who are clinically stable. 相似文献

The objective of this study was to investigate whether nitric oxide (NO) inhalation might be an alternative strategy as a chemical assist for the circulation in patients showing a deterioration in oxygen delivery. Twelve adult patients whose oxygen delivery indices (DO2I) were less than 400 ml/min/m2 after cardiovascular surgery were included in this study. NO was administered via a premixing system or a side stream system at doses between 1 and 10 (5.1+/-2.4) ppm. Data obtained before and during a 120 min NO inhalation were compared using the paired Student's t-test. The increase in PaO2/FiO2 resulting from NO inhalation was significant (from 162 to 251 mm Hg). DO2I increased significantly from 326 to 417 ml/min/m2 concomitantly with significant increases in both arterial oxygen content (CaO2) and cardiac index (CI) (from 14.1 to 15.4 vol% and from 2.31 to 2.71 L/min/m2 , respectively). The increase in SvO2 during NO inhalation was significant (from 55.2 to 62.6%). Among the other hemodynamic parameters, both total pulmonary resistance and systolic pulmonary arterial pressure (SPAP) showed significant decreases during NO inhalation, but right atrial pressure did not change significantly. There was a close relationship between the baseline SPAP level (bSPAP) and the decrease in SPAP during NO inhalation (dSPAP) (r = -0.88). However, negative correlations were observed between bSPAP and percentage increase in CI (%CI) (r = -0.61) and between bSPAP and percentage increase in DO2I (%DO2I) (r = -0.48). Moreover, positive relationships were observed between dSPAP and %CI (r = 0.62) and between dSPAP and %DO2I (r = 0.45). Hemoglobin (Hb) increased significantly from 11.0 to 11.4 g/dl. There were no significant changes in Fio2, pH, PacO2, or base excess (BE) during NO inhalation. The level of methemoglobin measured during the study period remained within the normal range (0.86+/-0.23%). In conclusion, NO inhalation could be an efficient and alternative assist for the circulation in patients whose oxygen delivery deteriorates after cardiovascular surgery. 相似文献

This report concerns one case of a sphenoid sinus mucocele occurring 17 years after transsphenoidal surgery for acromegaly.
In 1979, a 51-year-old man was successfully operated by the transnasal transsphenoidal approach for a growth hormone (GH)
adenoma 1 cm in diameter. In 1996, the patient was hospitalized for headaches and diplopia. He presented a loss of right visual
acuity with paralysis of the right oculomotor nerve. The basal GH level was normal with a satisfactory decrease after oral
glucose ingestion. Pituitary sellar radiography showed a disappearance of the posterior clinoid while magnetic resonance imaging
revealed the existence of a bilocular, circular, homogeneous lesion of the sphenoid sinus 3 cm in diameter with a posterior
and lateral extension. The diagnosis of mucocele was confirmed by surgical treatment, allowing drainage of the mucocele through
a transsphenoidal approach. The drained material was composed of sinus epithelium containing many polynuclear and resorptive
cells. Postoperatively, the symptoms decreased dramatically, leading to full recovery of visual function and disappearance
of the headaches. Apart from the tumor recurrence, the mucocele of the sphenoid sinus can be evoked as a possible long term
complication of transsphenoidal sugery for pituitary adenoma.

Craniofacial surgery concepts developed originally for reconstruction may also be applied to aesthetic surgery. The facial
skeleton is an important component of appearance and may be modified using common craniofacial surgery techniques. Three representative
male patients are presented, who each desired an improvement in his appearance. The techniques used were different and combined
orthognathic and remodeling procedures. Aesthetic male facial skeletal surgery was beneficial in these selected cases. The
results were well received and without complications. Surprisingly, we have found that male skeletal aesthetic patients did
not have unrealistic expectations and were pleasant to manage pre- and postoperatively. 相似文献
