Perceptions of palliative care in a South Asian community: findings from an observational study
2020
Background
Patients often view “palliative care” (PC) as an approach that is synonymous with end-of-life and death, leading to shock and fear. Differing cultural and social norms and religious affiliations greatly determine perception of PC among diverse populations.
Methods
This prospective observational study aimed to explore perceptions of PC among South Asian community members at one Canadian site. Patients who identified themselves as being of South Asian origin were consented and enrolled at a PC Clinic at a community hospital in Brampton, Ontario serving a large South Asian population. Participants filled out an 18-question survey created for the study and responded to a semi-structured interview consisting of 8 questions that further probed their perceptions of PC. Survey responses and semi-structured interviews content were analyzed by four authors who reached consensus on key exploratory findings.
Results
Thirty-four participants of South Asian origin were recruited (61.8% males), and they were distributed by their age group as follows: [(30–49) - 18%; (50–64) – 21%; (65–79) - 41%; (≥ 80) – 21%]. Five main exploratory findings emerged: (i) differing attitudes towards talking about death; (ii) the key role of family in providing care; (iii) a significant lack of prior knowledge of PC; (iv) a common emphasis on the importance of alleviating suffering and pain to maintain comfort; and (v) that cultural values, faith, or spiritual belief do not pose a necessary challenge to acceptance of PC services.
Conclusions
Observations from this study provide a source of reference to understand the key findings and variability in perceptions of palliative care in South Asian communities. Culturally competent interventions based on trends observed in this study could assist Palliative Physicians in delivering personalized care to South Asian populations.

Surgical resection of non-functioning pituitary neuroendocrine tumors (NF-PitNET) is associated with new onset hormonal axis (HA) dysfunction, and factors predicting HA dysfunction are controversial, especially in large and giant NF-PitNET. Thus, we evaluated the postoperative hormonal function and assessed factors affecting HA dysfunction in patients with NF-PitNET. This prospective observational study involved 50 patients who underwent endoscopic surgical resection of NF-PitNET in the Department of Neurosurgery (April 2023–March 2024). The preoperative tumor diameter and volume were calculated radiologically. Hormonal evaluation was performed preoperatively, and again postoperatively at 7-days and 90-days. At 90-days, 36% patients recovered HA function, 34% remained unchanged, while 30% worsened. Serum cortisol (
p
< 0.0001), adrenocorticotropic hormone (
p
= 0.012), growth hormone (
p
= 0.013), and luteinizing hormone (
p
= 0.020) levels increased significantly; serum prolactin (
p
= 0.016) decreased significantly; while serum thyroid-stimulating hormone, follicle-stimulating hormone, and testosterone levels remained unchanged (all
p
> 0.05). Overall, there was no significant change in grade of HA dysfunction (
p
> 0.05). Male sex (OR:5.630, 95%CI:1.648–19.232;
p
= 0.006), tumor volume (OR:3.511, 95%CI:1.308–9.423;
p
= 0.013) and tumor diameter (OR:9.489, 95%CI:2.916–30.878;
p
< 0.0001) were significantly associated with postoperative HA dysfunction. Tumor volume and diameter (cut-off: 8.87 cm
3
and 2.95 cm, respectively) predicted postoperative HA dysfunction with a sensitivity of 96.0% and 92.0%, and a specificity of 88.0% and 76.0%, respectively. New-onset diabetes insipidus (30%) was the predominant complication. Tumor diameter and volume are significant predictors of postoperative HA dysfunction. More than one third of patients improved their HA function, while it worsened in less than a third of patients.

Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications.
HIP ATTACK was an international, randomised, controlled trial done at 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were aged 45 years or older were eligible. Research personnel randomly assigned patients (1:1) through a central computerised randomisation system using randomly varying block sizes to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. The coprimary outcomes were mortality and a composite of major complications (ie, mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Patients, health-care providers, and study staff were aware of treatment assignment, but outcome adjudicators were masked to treatment allocation. Patients were analysed according to the intention-to-treat principle. This study is registered at ClinicalTrials.gov (NCT02027896).
Between March 14, 2014, and May 24, 2019, 27 701 patients were screened, of whom 7780 were eligible. 2970 of these were enrolled and randomly assigned to receive accelerated surgery (n=1487) or standard care (n=1483). The median time from hip fracture diagnosis to surgery was 6 h (IQR 4–9) in the accelerated-surgery group and 24 h (10–42) in the standard-care group (p<0·0001). 140 (9%) patients assigned to accelerated surgery and 154 (10%) assigned to standard care died, with a hazard ratio (HR) of 0·91 (95% CI 0·72 to 1·14) and absolute risk reduction (ARR) of 1% (−1 to 3; p=0·40). Major complications occurred in 321 (22%) patients assigned to accelerated surgery and 331 (22%) assigned to standard care, with an HR of 0·97 (0·83 to 1·13) and an ARR of 1% (−2 to 4; p=0·71).
Among patients with a hip fracture, accelerated surgery did not significantly lower the risk of mortality or a composite of major complications compared with standard care.

Background: Growing skull fracture (GSF)/pseudomeningocele is a rare complication of head injury in children. Post-traumatic intradiploic arachnoid cyst (PTIAC) is a variant but it is extremely rare. PTIACs are usually asymptomatic or with mild symptoms like headache. The rupture of PTIAC due to re-trauma leading to pseudomeningocele formation has not been seen or reported before. Patient and Method: We present a case of occipital PTIAC where pseudomeningocele developed after re-trauma, and discuss the pathogenesis and management. Result: En masse removal of the ruptured PTIAC was performed along with dural-defect repair. The post-operative recovery was good. Conclusion: PTIAC is an extremely rare occurrence as a variant of GSF. It is usually asymptomatic, but it may rupture with trivial trauma due to a thinned-out outer table and then converts into pseudomengocele. En masse excision with dural-defect repair gives good results in cases of ruptured PTIAC due to re-trauma.

Primary CNS vasculitis (PCNSV): a cohort study
2022
Primary CNS Vasculitis (PCNSV) is a rare inflammatory disorder affecting the blood vessels of the central nervous system. Patients present with a combination of headaches, seizures, and focal neurological deficits. There is usually a diagnostic delay. Treatment is based on observational studies and expert opinion. Our objective was to identify clinical, laboratory, neuroimaging, pathologic or management-related associations with 2 year outcome in patients with primary CNS vasculitis. We conducted a cohort study at a single tertiary care referral centre of prospectively (2018-2019) and retrospectively (2010-2018) identified individuals with primary CNS vasculitis (diagnosis was proven by either brain biopsy or cerebral digital subtraction angiography). Clinical, imaging and histopathologic findings, treatment, and functional outcomes were recorded. Univariate and stepwise multiple logistic regression were applied. P-value<0.05 was considered statistically significant. The main outcome measures were documentation of clinical improvement or worsening (defined by mRS scores) and identification of independent predictors of good functional outcome (mRS 0-2) at 2 years. We enrolled eighty-two biopsy and/or angiographically proven PCNSV cases. The median age at presentation was 34 years with a male predilection and a median diagnostic delay of 23 months. Most patients presented with seizures (70.7%). All patients had haemorrhages on MRI. Histologically lymphocytic subtype was the commonest. Corticosteroids with cyclophosphamide was the commonest medication used. The median mRS at follow-up of 2 years was 2 (0-3), and 65.2% of patients achieved a good functional outcome. Myelitis and longer duration of illness before diagnosis were associated with poorer outcomes. The presence of hemorrhages on SWI sequence of MRI might be a sensitive imaging marker. Treatment with steroids and another immunosuppressant probably reduced relapse rates in our cohort. We have described the third largest PCNSV cohort and multi-centre randomised controlled trials are required to study the relative efficacy of various immunosuppressants.

Sporadic late-onset nemaline rod myopathy is a rare, acquired, sub-acute, adult-onset myopathy characterized by proximal muscle weakness and nemaline rods in the myofibers. In contrast to its congenital form, the prevalence in adult population is comparatively rare. Herein, we report a case of 60-year-old male who presented with insidious onset proximal muscle weakness with myopathic pattern on electromyography. Histopathological examination showed type 1 and 2 muscle fiber atrophy with minimal chronic inflammatory cell infiltrate. Modified Gomori trichrome staining revealed granular deposits in the myofibers. Ultrastructure examination showed numerous nemaline rods in the myofibers; hence, the diagnosis of sporadic late-onset nemaline myopathy was rendered. Its association with monoclonal protein has been reported in the past. One should be aware of this rare entity as without correct diagnosis, there can be treatment failure and unfavorable outcome.

Neurosarcoidosis (NS) is a protean illness with multiple clinical and radiological presentations giving it the moniker of \"a chameleon\" or the great mimic. NS can present as a wide spectrum of neurological syndromes localizing both to the central and peripheral nervous systems. The absence of a diagnostic serum test makes it difficult to diagnose with certainty and remains largely a histopathological diagnosis and one of exclusion. A high index of suspicion should be there in suspecting NS, and it should always be excluded among patients presenting with acute to subacute neurological deficits.

The role of susceptibility-weighted imaging & contrast-enhanced MRI in the diagnosis of primary CNS vasculitis: a large case series
2024
Primary CNS Vasculitis (PCNSV) is a rare, diverse, and polymorphic CNS blood vessel inflammatory condition. Due to its rarity, clinical variability, heterogeneous imaging results, and lack of definitive laboratory markers, PCNSV diagnosis is challenging. This retrospective cohort analysis identified patients with histological diagnosis of PCNSV. Demographic data, clinical presentation, neuroimaging studies, and histopathologic findings were recorded. We enrolled 56 patients with a positive biopsy of CNS vasculitis. Most patients had cerebral hemisphere or brainstem symptoms. Most brain MRI lesions were bilateral, diffuse discrete to confluent white matter lesions. Frontal lobe lesions predominated, followed by inferior cerebellar lesions. Susceptibility-weighted imaging (SWI) hemorrhages in 96.4% (54/56) of patients, either solitary microhemorrhages or a combination of micro and macrohemorrhages. Contrast-enhanced T1-WIs revealed parenchymal enhancement in 96.3% (52/54 patients). The most prevalent pattern of enhancement observed was dot-linear (87%), followed by nodular (61.1%), perivascular (25.9%), and patchy (16.7%). Venulitis was found in 19 of 20 individuals in cerebral DSA. Hemorrhages in SWI and dot-linear enhancement pattern should be incorporated as MINOR diagnostic criteria to diagnose PCNSV accurately within an appropriate clinical context. Microhemorrhages in SWI and venulitis in DSA, should be regarded as a potential marker for PCNSV.
