Therefore, patients with Duret haemorrhage of the mid-brain caused by simple subdural haematoma presenting with bilateral oculomotor palsy, including bilateral pupillary dilation, may not always have a poor prognosis.

[Purpose] Diffusion tensor imaging (DTI) has attracted attention as a method for determining prognosis following paralysis after stroke. However, DTI can assess the degree of damage to the corticospinal tract but cannot evaluate other brain regions. In this study, we examined in detail the prognosis of upper-limb function of the paralyzed side following stroke, using DTI and voxel-based morphometry (VBM). [Subjects and Methods] We studied 17 consecutive patients diagnosed with stroke, including hemorrhagic and ischemic types, who exhibited hemiparesis and were treated in our hospital. DTI and VBM were performed 14 days after admission. Outcome measurements that assessed upper limb function were Fugl-Meyer Assessment (FMA) and Motor Activity Log (MAL), which were applied after 3 months. [Results] The fractional anisotropy ratio of the bilateral cerebral peduncles (rFA) was significantly correlated with FMA, amount of use, and quality of movement 3 months after stroke. The precentral gyrus significantly degenerated as compared with the control group for a case with notable motor paralysis, for which rFA was high. [Conclusion] We suggest it may be possible to predict recovery of upper limb function following stroke by combining DTI and VBM visualization methods.

Ventriculoperitoneal shunts (VPS) and gastrostomies are frequently provided in daily practice. This study investigated the incidence of VPS infection and the survival rate among adult patients who underwent gastrostomy at least 1 month after VPS placement. This single-center retrospective cohort study was conducted among patients with a VPS, who underwent a gastrostomy. This procedure was performed on a standby basis after a period of at least 1 month had elapsed since VPS placement. Subsequent VPS infection and survival rates were assessed over a period of at least 6 months. We reviewed 31 patients who had a VPS at the time of gastrostomy. Gastrostomy was performed endoscopically in 29 cases and via open surgery in 2 cases. The average interval between VPS insertion and gastrostomy was 1135.5 ± 1717.1 days. A single case of VPS infection (3.2%) was diagnosed during the study. This infection rate was not significantly different than that among 230 patients who underwent their first VPS placement (without gastrostomy) at our institution during the same time period (P = .57); there was also no significant difference in the survival rate, compared to 38 age-matched patients (with cerebrovascular disease, but without a VPS) who underwent gastrostomy (P = .73). Gastrostomy performed after an interval of at least 1 month after VPS placement was extremely safe in adult patients, and their prognosis was excellent. Additional studies are required to develop appropriate nutritional interventions for patients with a VPS.
