Minimally invasive lumbar fusion is well described and is reported to offer significant advantages to patients in terms of blood loss, a reduction in post-operative pain and a quicker recovery. However, this technique may expose patients to a greater risk of complications when compared to open lumbar instrumented fusion that may negate these advantages. Between January 2007 and March 2001, we conducted a prospective observational study of 100 consecutive patients (48 males and 52 females, mean age of 54 years) to investigate complications occurring from minimally invasive lumbar interbody fusion surgery using an image-guided technique. ⋯ There were no occurrences of infection and no cerebrospinal fluid leaks. We concluded that the rate of complications from minimally invasive lumbar interbody fusion is low, and compares favourably with the rates of complication from open procedures. Moreover, computerised navigation systems can be used in place of real-time fluoroscopy to guide implant placement, without an increase in the rate of complications.

Subarachnoid hemorrhage (SAH) often leads to hydrocephalus, which is commonly treated by placement of a ventriculoperitoneal (VP) shunt. There is controversy over which factors affect the need for such treatment. In this study, data were prospectively collected from 389 consecutive patients who presented with an aneurysm-associated SAH at a single center. ⋯ Patients with an initial GCS score of 8-14 after aneurysm-associated SAH had a 2.5-fold higher risk of receiving a VP shunt than those with a GCS score of 3-7. Those with a GCS of 15 had a 50% lower risk of becoming shunt dependent than did the subgroup with a GCS score of 8-14. To clarify and strengthen these observations, prospective, randomized trials are needed.

We present a 3-year-old girl with a transoral injury by a bamboo chopstick penetrating the middle skull base. The features of imaging are described and the management is discussed. The potential for injury to the cavernous sinus is emphasized, even if no there is no hemorrhage on the initial CT scan. Early intracranial infection in relation to penetrating injuries is a factor in planning treatment by craniotomy.

Cerebral sinodural thrombosis (CSDT) is a rare complication of minor head trauma in children. Despite recommendations, anticoagulation is frequently withheld. We aimed to evaluate the etiology, clinical presentation, risk factors, diagnosis, treatment, and outcome of pediatric CSDT following minor head trauma, and specifically to evaluate factors associated with anticoagulation use following minor head trauma in pediatric patients with CSDT. ⋯ One patient required lumboperitoneal shunt placement. Pediatric CSDT is a rare complication of minor head trauma, with variable presentation. Anticoagulation has generally been reserved for patients suffering from severe symptoms, for those who deteriorate neurologically during observation, and for those who suffer from a concomitant prothrombotic disorder.

Encephalitis associated with antibodies against N-methyl-d-aspartic acid (NMDA) receptor is characterized by severe memory deficits, decreased consciousness, epileptic seizures and movement disorders and occurs most commonly in young women. Recovery is mostly good but little is known about the disease course in patients whose treatment has been delayed severely. We present a 16-year-old girl with a 36-month follow-up. ⋯ Spontaneous recovery independent of therapy is possible, as it has been observed previously as late as 3years after onset. Although serum antibodies disappeared with recovery in this patient, previous cases have shown serum antibodies to be unreliable markers of disease activity. Second-line treatment, especially with substances as well tolerated as rituximab, should at least be considered in NMDA receptor encephalitis with persistent neuropsychiatric syndromes after first-line therapy.
