Fulltext Initial leucocytosis and other significant indicators of poor outcome in severe traumatic brain injury: an observational study

Vijian K, Teo EG, Kanesen D, Wong ASH

Chinese neurosurgical journal, 2020;6:5.
PMID: 32922934 DOI: 10.1186/s41016-020-0185-4

Background: Globally, severe traumatic brain injury (TBI) has been the principal cause of mortality among individuals aged 45 and below. The incidence of road traffic accidents in Malaysia is one of the highest in the world with thousands of victims sustaining severe disabilities. The aim of this study is to determine the association between leucocytosis and extended Glasgow Outcome Scale (GOSE) scores as well the relationship of other factors and the outcomes of severe TBI.
Methods: This was a retrospective observational study. A total of 44 consecutive patients who were admitted to Sarawak General Hospital from January 1, 2018, to September 30, 2018, with severe TBI were included. Data were collected from discharge summaries and hospital medical records. Chi-square and t test were used. SPSS was employed.
Results: Of a total of 44 patients with severe TBI, 18 patients (41%) died during the same admission. The mean age of patients was 37.1 years with 93.2% of affected patients being male. 56.9% of patients presented with a Glasgow Coma Scale (GCS) of 6 and less. A large percentage (86.3%) were discharged with a GOSE of less than 7. Older age and low admission GCS (6 and less) were significantly associated with poor GOSE scores on discharge and after 6 months (p < 0.05) on multivariate analysis. Leucocytosis on admission was also associated with poor outcomes where patients with higher total white counts on presentation attaining lower GOSE scores (p < 0.05).
Conclusion: We concluded that leucocytosis was significantly associated with poor outcomes in severe TBI patients in addition to other factors such as advanced age and poor GCS on arrival.
Factors affecting diagnostic yield in stereotactic biopsy for brain lesions: a 5-year single-center series

The objective of this study is to determine the factors that are associated with the diagnostic yield of stereotactic brain biopsy. A retrospective analysis was performed on 50 consecutive patients who underwent stereotactic brain biopsies in a single institute from 2014 to 2019. Variables including age, gender, lesion topography and characteristics, biopsy methods, and surgeon's experience were analyzed along with diagnostic rate. This study included 31 male and 19 female patients with a mean age of 48.4 (range: 1-76). Of these, 25 underwent frameless brain-suite stereotactic biopsies, 15 were frameless Portable Brain-lab® stereotactic biopsies and 10 were frame-based CRW® stereotactic biopsies. There was no statistical difference between the diagnostic yield of the three methods. The diagnostic yield in our series was 76%. Age, gender, and biopsy methods had no impact on diagnostic yield. Periventricular and pineal lesion biopsies were significantly associated with negative diagnostic yield (p = 0.01) whereas larger lesions were significantly associated with a positive yield (p = 0.01) with the mean volume of lesions in the positive yield group (13.6 cc) being higher than the negative yield group (7 cc). The diagnostic yields seen between senior and junior neurosurgeons in the biopsy procedure were 95% and 63%, respectively (p = 0.02). Anatomical location of the lesion, volume of the lesion, and experience of the surgeon have significant impacts on the diagnostic yield in stereotactic brain biopsy. There was no statistical difference between the diagnostic yield of the three methods, age, gender, and depth of lesion.
Fulltext Manual Muscle Testing of the Scapula and the Upper Limb through Bedside Examination

Vijian K, Cheng YT, Idris Z, Izaini Ghani AR, Abdul Halim S, Abdullah JM

Malays J Med Sci, 2023 Feb;30(1):198-212.

Neurological examination is an important tool in diagnosing patients with neurological and neurosurgical conditions. As the complexity and knowledge of neurological and neurosurgical conditions increases, we are now required to learn and indoctrinate our peers and students with the correct skills and methods of examination. Emphasis on the correct techniques of testing muscle strength is essential to avoid errors in recording muscle power and in testing specific muscles which may have overlapping functions. The manual muscle testing of muscles of scapula and upper limbs was performed as to mimic a bedside clinical examination and involved an examiner, a patient and a videographer. The manual muscle testing has been performed in rostrocaudal manner starting from the scapula and ending with the thumbs. A reliable and consistent method of manual muscle testing is lacking among students and clinicians. By adhering to the methods delineated in our text and accompanying video, we hope to reduce inter-examiner variability and increase the reliability and validity of this important examination.
