Previous studies have identified the impact of affective disorders on preoperative and postoperative perception of pain. However, there is a scarcity of data identifying the impact of affective disorders on postdischarge narcotic refills. The aim of this study was to determine whether patients with affective disorders have more narcotic refills after complex spinal fusion for deformity correction. ⋯ Our study suggests that whereas spinal deformity patients with affective disorders may have a higher baseline perception of pain and narcotic use, the impact of affective disorders on narcotic refills at 6 weeks and 3 months may be minimal after complex spinal fusion.

Diverse adipose lesions can affect peripheral nerves, including an intrinsic disorder known as lipomatosis of nerve (LN). This condition leads to massive nerve enlargement and has often been associated with nerve territory overgrowth. Although LN has been well documented as a peripheral lesion, it is uncertain whether LN can occur or extend intradurally. ⋯ A review of our institutional cases and reported cases did not show any example of LN extending or occurring intradurally. It appears that LN is a benign tumor-like nerve lesion that is without a central location, unlike more well-known tumors such as schwannomas.

The optimal management of dural closure is unclear; therefore, we aimed to survey current common practices among Italian practitioners. ⋯ This study elucidates the areas of consensus and uncertainty on dural closure management among a group of Italian neurosurgeons. It provides reliable and comparable data for the investigation of the departments' daily practice in dural closure. Given the lack of solid evidence, there is a need for further comparative studies of dural repair strategies.

Dumbbell-shaped spinal schwannomas with intradural and extradural components are associated with higher complication rates. This may be in part due to epineurial dissection of the extradural component, which inevitably damages the functioning nerve fibers beneath the epineurium and may lead to dural defects that are often difficult to repair. ⋯ The radical intracapsular dissection technique described herein represents an alternative technique for the removal of dumbbell-shaped spinal schwannomas with intradural and extradural components.

Large epileptogenic type IIIb dysplasia: a radiological and anatomopathological challenge.
Type IIIb dysplasia is a subtype of focal cortical dysplasia associated with a tumor, most frequently with gangliogliomas then with dysembryoplastic neuroepithelial tumors (DNETs). Their preoperative diagnosis often remains equivocal since specific features are missing. The functional results (i.e., seizure free) is good with 81%-87% of Engel Ia at 5-year follow-up. ⋯ We describe a rare condition of type IIIb dysplasia combining a focal cortical dysplasia with a DNET. Preoperative diagnosis of the lesion was of utmost difficultly, thereby rendering mandatory a thorough histopathological examination of resected specimen in the vast majority of cases. Increased recognition of the condition brings up the hypothesis of a genetic continuum or linkage between the 2 conditions. Functional results on seizure activity after ablative surgery are good and maximal safe resection should be the goal.
