Exacerbation of Partial Seizures and Onset of Nonepileptic Myoclonus with Carbamazepine

A child had two to three generalized tonic-clonic (GTC) seizures per week unresponsive to phenobarbital (PB) and valproate (VPA). Interictal EEG demonstrated left occipital spikes. When carbamazepine (CBZ) therapy was started, he developed very frequent (4-6/day) complex partial seizures (CPS) characterized on ictal EEG by focal right temporal lobe discharges. The seizure exacerbation, which was associated with development of nonepileptic, multifocal myoclonus, resolved 24 h after CBZ was discontinued. The exacerbation occurred with therapeutic CBZ serum levels, but may have been related to the toxic levels of carbamazepine-10, 11-epoxide (CBZE).

后腹腔镜下肾肿瘤剜除术的临床疗效观察(附5例报告)

目的：探讨后腹腔镜下肾肿瘤剜除术的操作要点及临床价值。方法：采用后腹腔镜下肾肿瘤剜除术治疗肾肿瘤5例，其中肾癌3例，肾错钩瘤2例，瘤体直径1．5～4．0cm。具体方法是：①暴露瘤体和肾动脉；②采用硅胶管牵拉肾动脉，必要时可暂时阻断肾动脉；③于瘤体1cm正常肾组织处用电钩切除瘤体；④采用生物蛋白胶、止血纱布缝合加压处理创面出血。结果：手术均获成功。手术时间150～210min，术中出血80～350ml。术后1～2天肠道功能恢复并可床上活动，1～4天可下床活动。术后住院5～9天，平均7天。结论：后腹腔镜下肾肿瘤剜除术具有创伤小、康复快、安全、住院时间短等优点；对外生性生长、直径小于4cm瘤体，该法可作为首选手术方法。

SDZ 208-911, an amino-ergoline with partial dopamine agonist properties,dose dependently increases cocaine self-administration in the rat

Brain dopamine neurotransmission appears to be an important component of the neural pathways involved in the maintenance of intravenous (IV) cocaine self-administration in rats. The effects of a novel partial dopamine agonist, SDZ 208–911, on intravenous cocaine self-administration in rats was studied. SDZ 208–911 at a dose range of 0.025–1.6 mg/kg SC dose-dependently increased the number of lever presses and drug intake in rats exposed to limited (3-h) daily access to cocaine on a continuous reinforcement schedule (0.75 mg/kg per injection). This behavioral profile is similar to that observed following administration of dopamine antagonist drugs and has been hypothesized to reflect a compensatory increase in drug intake due to a reduction of the reinforcing efficacy of the drug, probably because of functional antagonism at the receptor site. These results suggest that dopamine partial agonists may act as functional dopamine antagonists in the face of pharmacologically induced activation of brain dopamine function.     

HIPDM single photon emission computed tomography brain imaging in partial onset secondarily generalized tonic-clonic seizures

HIPDM-Single photon emission computed tomography brain imaging was performed during interictal and ictal stages in three patients with complex partial seizures and secondarily generalized tonic-clonic seizures. In all three patients, interictal studies demonstrated decreased regional cerebral perfusion (rCP) and ictal studies showed increased rCP in the epileptogenic region. The demonstration of focal hyperperfusion by SPECT performed during secondarily generalized tonic-clonic seizures suggests that rCP in the epileptic focus remains higher than in other cerebral regions during immediate postictal stages, even in secondarily generalized seizures.

Unique variant of partial anomalous pulmonary venous connection with intact atrial septum

Summary Partial anomalous pulmonary venous connections (PAPVCs) are rare in association with an intact atrial septum. However, the diagnosis should be considered in patients with otherwise unexplained findings of left-to-right shunt and right heart enlargement. An unusual variant is presented, which we considered unsuitable for operative repair, based on findings at catheterization. Developmental, hemodynamic, and surgical considerations are discussed.
