Comparative Study
Comparison of consecutive, interval, and skipped pedicle screw techniques in moderate Lenke type 1 adolescent idiopathic scoliosis.
To compare perioperative, radiographic, and Scoliosis Research Society-22 (SRS-22) outcomes of consecutive, interval, and skipped pedicle screw techniques in patients with moderate Lenke type 1 adolescent idiopathic scoliosis (AIS). ⋯ Consecutive, interval, and skipped pedicle screw techniques all provide satisfactory deformity correction and SRS-22 outcomes with few complications. With better perioperative outcomes, interval and skipped pedicle screw techniques are the more cost-effective options for patients with moderate Lenke type 1 AIS.

To propose a modified classification system for spontaneous intracranial dissecting aneurysms (IDAs) that can guide treatment decisions. ⋯ There was a strong relationship between the subtypes of spontaneous IDAs and clinical course. Our classification system is confirmed to be helpful in assessing patients' prognosis and guiding their treatment.

The mainstay treatment of primary malignant bone tumors is wide surgery in the spine. Unfortunately, most cases undergo the first approach in a nonspecialized center; this often means adopting an inappropriate approach with contamination, which consistently decreases the effectiveness of a second surgery. The aim of the present paper is to evaluate recurrence and survival rates after en-bloc resection. ⋯ In our series, the first inappropriate approach had already compromised patient prognosis, so in case of suspicious primary spine tumor, the patient had to be referred to a specialized center. The margin obtained during salvage surgery does not appear to influence recurrence and survival, probably because it is already compromised by the first surgery. More prospective studies are necessary to confirm our data and verify the impact of the margin obtained during salvage surgery on patients' survival.

Transient loss of consciousness (LOC) is one of the most common presentations of aneurysmal subarachnoid hemorrhage (SAH) and may be an indicator of early brain injury. In this study, we examined the association of LOC and functional outcomes in patients with good-grade SAH. ⋯ LOC at ictus of SAH is associated with a higher rate of unfavorable functional outcomes but not of mortality, DCI, or rebleed in patients with good-grade SAH. Future studies should further investigate the putative mechanisms through which LOC mediates early brain injury in SAH.

Observational Study
A High-Resolution Analysis on the Meteorological Influences on Spontaneous Intracerebral Hemorrhage Incidence.
To investigate the influence of meteorological factors on the incidence of intracerebral hemorrhage (ICH). ⋯ By using high-quality meteorological data analyzed with a sophisticated and robust statistical method that minimizes the confounding effect of seasonality, no clearly identifiable meteorological influence for the ICH events considered can be found.
