RESUMEN
Background Stroke is one of the leading causes of disability, long-term morbidity, and mortality. The key modifiable risk factors for stroke are largely driven by demographic changes and various social adaptations. Smokeless tobacco consumption is high in developing countries with less awareness of its potential health risks. Aim This study was designed to determine the prevalence of usage of smokeless tobacco in patients presenting with stroke in a tertiary care hospital in Karachi. Methods This is a cross-sectional study conducted at the Department of Neurology of Dr. Ruth K. M. Pfau Civil Hospital in Karachi. A total of 192 patients were enrolled during the study period of six months, from September 2018 to March 2019. All consenting patients were recruited who presented with stroke and fulfilled the inclusion criteria. All patients were assessed by a trained neurologist. Results A total of 192 patients with stroke were included. There were 146 (76%) males and 46 (24%) females with a mean age of 53 ± 6.1 years. The highest percentage (39%) of cases was illiterate. A majority (64%) of patients presented belonged to a lower socioeconomic background. Out of 192 stroke patients, 131 (68.2%) consumed smokeless tobacco. Conclusion The frequency of smokeless tobacco consumption was found to be high in stroke patients who require the attention of the physician on modifiable risk factors.
RESUMEN
Introduction Guillain-Barré syndrome (GBS) is defined as a syndrome manifesting as an acute inflammatory demyelinating polyradiculoneuropathy (AIDP) with coexistent weakness and absent or diminished reflexes clinically.Autonomic dysfunction (AD) or dysautonomia is a common finding in GBS. Autonomic dysfunction usually occurs in the acute phase of the illness but can also be seen in the recovery phase. The rationale of our study is to determine the frequency of autonomic dysfunction in patients of GBS admitted to the Neurology department of Civil Hospital, Karachi. Methods A total of 118 admitted patients at a tertiary care hospital in Pakistan who fulfilled the inclusion criteria were enrolled in the study after informed consent. The study was conducted for six months at the department of neurology, Civil Hospital, Karachi. Patients were assessed for autonomic dysfunction by recording blood pressures and pulse rate hourly (both lying and standing positions) by resident doctors. Urinary retention, diarrhea, and constipation were also recorded in a separate chart. All values entered in the pre-approved performa by researchers. The data was collected and analyzed on Statistical Package for Social Sciences (SPSS) version 18.0 (IBM Corp., Armonk, NY, USA). Descriptive statistics included mean, standard deviation (SD) of continuous data, like age, duration of illness, motor weakness assessment by Medical Research Council (MRC) Scale, protein content in cerebrospinal fluid (CSF), pulse, and blood pressure at the time of presentation. Frequencies and percentages were calculated from the categorical data, like gender and patients with autonomic dysfunction (outcome variable). Effect modifiers were controlled by stratification of age, gender, duration of illness. Post-stratification chi-square test was applied with a p-value of ≤ 0.05 taken as significant. Results In our study, the average age of the patients was 39.90±9.91 years. Frequency of autonomic dysfunction among patients with GBS was 41.53% (49/118). The most frequent autonomic manifestations were constipation and diarrhea; 22% and 21.2% respectively. Additional manifestations included urinary retention (15.3%) and fluctuation of blood pressure and heart rate at 13.6% each. Conclusion This study showed that the frequency of autonomic dysfunction among patients of Guillain Barre Syndrome was significant, consistent with previous studies. Our study explored the adverse outcomes of autonomic dysfunction in patients with GBS. This will help physicians increase their understanding of dysautonomia so that effective management plans can be formulated for patients with GBS to prevent adverse outcomes and hence provide better patient care.
