Background and objectives: Intracerebral hemorrhage (ICH) is associated with high mortality and morbidity. Uncertainty still exists regarding the benefit of surgery in the management of supratentorial spontaneous ICH (sICH), especially of the basal ganglia and thalamus. Studies have not shown the clinical benefit of early surgical management compared to best medical management plus delayed surgery, when necessary. Our aim was to compare the efficacy of different neurosurgical interventions with best medical management and best medical management alone.

Methods: We conducted a single-center, retrospective study at a tertiary care center in India in sICH patients between January 2015 and December 2022. The primary outcome was functional disability evaluated by the modified Rankin Scale (mRS) at 3, 6, and 12 months. Time-to-event outcomes were compared using the Kaplan-Meier curve.

Results: Among 2600 stroke patients screened, 661 had sICH. Median age was 55 years, and 250 patients (37.8%) underwent neurosurgical intervention. The most common intervention was craniotomy and hematoma evacuation. The median mRS at discharge and follow-up at 3, 6, and 12 months was lower in the conservatively managed group (4, 3, 3, and 3, respectively) compared to the surgical intervention group (5, 5, 5, 4, respectively). However, the ICH score at admission was lower in the conservatively managed group and after adjustment for ICH score, there was no statistically significant difference between the two. Among the interventions, patients undergoing decompression craniectomy had the best functional outcome.

Conclusions: Neurosurgical intervention was not associated with better functional outcome when compared to conservative management.

Abstract: Cyclosporine and tacrolimus belong to the immunosuppressive drugs of the calcineurin inhibitors group. They are widely used in the treatment of patients after organ transplants. One of their complications is neurotoxicity, the mechanism of which is still not fully understood. The main risk factor for neurotoxicity is hypertension. The most common symptoms include muscle tremors, which are more common in the upper limbs, as well as migraine headaches and peripheral neuropathies. The diagnosis of neurotoxicity is based on imaging tests (magnetic resonance imaging being the most commonly used) and assessment of clinical symptoms. Preventive measures should be initiated as soon as possible to prevent permanent damage to the nerve tissue. The possible preventive methods include reduction of the dose of the administered drug, temporary or complete discontinuation of drugs, or conversion to another immunosuppressive drug. It is also essential to monitor the patient's condition, correct hypertension, electrolyte disturbances, and fight possible infections. So far, effective methods of preventing calcineurin inhibitor-induced neurotoxicity have not been demonstrated.

Abstract: "Tardive syndrome" is an umbrella term for a group of drug-induced movement disorders associated with the prolonged use of mainly dopamine receptor blockers and also other medications. Early recognition followed by gradual withdrawal of the incriminating drug may lead to reversal, although not in all patients. Tardive syndromes are usually mixed movement disorders, with specific phenotypes, which may lead to severe disability. The pathophysiology remains incompletely understood. Treatment ranges from medical options, particularly dopamine-depleting agents and chemodenervation (botulinum toxin), to surgical options (deep brain stimulation and lesioning surgeries). Most studies that focused on treatment are limited by small patient numbers. Unfortunately, tardive syndromes often remain under-recognized in clinical practice. This article reviews the historical aspects, epidemiology and risk factors, pathophysiology, diagnostic criteria, clinical phenotypes, and management of tardive syndromes.

Background and objectives: Pain is an important non-motor symptom in Parkinson's disease (PD) and is often under-recognized. Pain is also a symptom frequently reported by non-PD elderly subjects. The King's Parkinson's Disease Pain Scale (KPPS) is a valid tool to characterize and quantify pain in PD and has been translated into several languages.

Methods: We translated KPPS to Malayalam for native patients with PD and examined the pain characteristics in consecutive patients. Correlations with comprehensive disease-specific rating scales, including the Movement Disorder Society-Sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the Non-Motor Symptoms Scale (NMSS), were explored. A group of age- and gender-matched subjects without PD were interviewed using KPPS to examine how the pain reported by the non-PD aging population is different from that in PD.

Results: In this study, 82% of patients with PD reported at least one type of pain, compared to 31.3% of age- and gender-matched control subjects (P < 0.001). KPPS total scores (18.2 ± 14.0 vs. 1.8 ± 3.2; P < 0.001) and all the individual domain scores were significantly higher in patients. Pain scores correlated with age in control subjects (R = 0.46, P < 0.001), but not in patients; females reported more pain in both groups. Patients' pain scores were higher in the postural instability and gait difficulty subtype and showed significant correlations with MDS-UPDRS and NMSS scores.

Conclusions: Pain is a prevalent symptom in PD and differs from the pain reported by a non-PD aging population. The Malayalam version of KPPS is a valid tool to characterize pain in native, Malayalam-speaking patients.
