Treatment and outcome of epileptogenic temporal cavernous malformations / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The aim of this study is to explore the treatment and outcome of epileptogenic temporal lobe cavernous malformations (CMs).</p><p><b>METHODS</b>We analyzed retrospectively the profiles of 52 patients diagnosed as temporal lobe CMs associated with epilepsy. Among the 52 cases, 11 underwent a direct resection of CM along with the adjacent zone of hemosiderin rim without electrocorticogram (ECoG) monitoring while the other 41 cases had operations under the guidance of ECoG. Forty-six patients were treated by lesionectomy + hemosiderin rim while the other six were treated by lesionectomy + hemosiderin rim along with extended epileptogenic zone resection. The locations of lesions, the duration of illness, the manifestation, the excision ranges and the outcomes of postoperative follow-up were analyzed, respectively.</p><p><b>RESULTS</b>All of the 52 patients were treated by microsurgery. There was no neurological deficit through the long-term follow-up. Outcomes of seizure control are as follows: 42 patients (80.8%) belong to Engel Class I, 5 patients (9.6%) belong to Engel Class II, 3 patients (5.8%) belong to Engel Class III and 2 patients (3.8%) belong to Engel Class IV.</p><p><b>CONCLUSION</b>Patients with epilepsy caused by temporal CMs should be treated as early as possible. Resection of the lesion and the surrounding hemosiderin zone is necessary. Moreover, an extended excision of epileptogenic cortex or cerebral lobes is needed to achieve a better prognosis if the ECoG indicates the existence of an extra epilepsy onset origin outside the lesion itself.</p>

Rotary self-locking intramedullary nail for long tubular bone fractures / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Intramedullary nails had been widely used in the treatment of long-bone fractures because of less interference of fractures and center bearing biomechanical advantage. However, it had been also found many shortcomings such as broken nails, delayed healing and was modified in order to achieve better efficacy and reduce complications. The aim of the present study is to compare the efficacy of rotary self-locking intramedullary nails (RSIN) with that of interlocking intramedullary nails (IIN) in the treatment of long-bone fractures.</p><p><b>METHODS</b>A retrospective study investigated 129 cases with long-bone fractures (36 with femoral fracture, 81 with tibial fracture, and 12 with humeral fracture). The fractures were fixed using either an RSIN or IIN. All patients underwent followup for 12-30 months.</p><p><b>RESULTS</b>All patients in both groups achieved a clinical fracture healing standard and the postoperative affected limb muscle strength and joint function were well restored. The RSIN group required a shorter operative time and the fracture healed faster. There was no significant difference in the hospital stay, intraoperative blood loss or postoperative complications between the two groups.</p><p><b>CONCLUSIONS</b>RSIN is used to treat long-bone fractures. Its healing efficacy is equivalent to the IIN. Moreover, the RSIN method is simpler and causes less tissue damage than the IIN, therefore having the advantage of accelerated healing.</p>
