Article Abstract
Background: Liver tumors invading the distal part of the umbilical portion of the left portal vein usually require left hepatectomy. The recent introduction of the concept of left anterior sector, an independent anatomo-functional unit including the anterior portion of the left liver and supplied by the distal part of the umbilical portion of the left portal vein, could represent the rational for an alternative surgical approach. The aim of this study was to introduce the novel surgical procedure of ultrasound-guided left anterior sectorectomy.
Methods: Among 92 consecutive patients who underwent hepatectomy, 3 patients with tumor invading the distal part of the umbilical portion of the left portal (two with colorectal liver metastases and one with neuroendocrine tumor liver metastases) underwent left anterior sectorectomy alone or in association with liver multiple metastasectomies.
Results: Mean operation time was 393 min; post-operative morbidity and mortality were not observed. After a mean FU of 23 months (range 19-28), no local recurrence occurred.
Conclusions: In presence of tumors invading the distal part of the umbilical portion of the left portal, left anterior sectorectomy could be considered as an anatomic radical surgical option that is safe but more conservative than a left hepatectomy.

Aim: Hydrocephalus is a condition characterized by the excessive accumulation of cerebrospinal fluid in the brain's ventricular system, leading to ventricular enlargement and increased intracranial pressure. This study aimed to evaluate whether transfontanel ultrasonography could serve as a practical and less complex alternative to brain magnetic resonance imaging in infants with hydrocephalus.
Material And Methods: In this prospective study, 54 infants diagnosed with hydrocephalus underwent both transfontanel ultrasonography and brain magnetic resonance imaging.
Right hemisphere language network plasticity in aphasia.

The role of the right hemisphere in aphasia recovery has been controversial since the 19th century. Imaging studies have sometimes found increased activation in right hemisphere regions homotopic to canonical left hemisphere language regions, but these results have been questioned due to small sample sizes, unreliable imaging tasks, and task performance confounds that affect right hemisphere activation levels even in neurologically healthy adults. Several principles of right hemisphere language recruitment in aphasia have been proposed based on these studies: that the right hemisphere is recruited primarily by individuals with severe left hemisphere damage, that transcallosal disinhibition results in recruitment of right hemisphere regions homotopic to the lesion, and that increased right hemisphere activation diminishes to baseline levels over time.

Background: The reliance on patient reported outcomes (PROs) has substantially increased not only to augment current metrics of clinical success, but to capture the patient's perspective on the benefit of their treatment. As more PROs become utilized, the time and cost of longitudinal data collection and survey fatigue must be tempered with the benefit of the data collected. Therefore, this study sought to assess the responsiveness of the Neck Disability Index (NDI) compared to the PROMIS-10 Global Health Survey physical function T-score (PFT) and mental health T-score (MHT).

Most individuals with moderate-to-severe diffuse axonal injury (DAI) have impaired verbal fluency (VF) capacity. Still, the relationship between brain and VF recovery post-DAI has remained mostly unknown. The aim was to assess brain changes in 13 cortical thickness regions of interest (ROIs), fractional anisotropy (FA), and free water (FW) in three language-related tracts; the VF performance at 6 and 12 months after the DAI; and whether brain changes from 3 to 6 months predict VF performance from 6- to 12-month post-DAI.

Background: The m.3243A>G mutation in the MT-TL1 gene is the most common mtDNA mutation. The mutation can lead to a spectrum of conditions, including diabetes, hearing loss, heart and muscle involvement, encephalopathy and epilepsy, gastrointestinal problems, and vision impairment, often occurring concurrently-collectively referred to as MELAS (mitochondrial encephalopathy lactic acidosis and stroke-like episodes) syndrome.
