IntroductionMigraine, a primary headache disorder, is usually recurrent with moderate to severe intensity. Migraine is the third most common cause of disability under the age of 50. There are various scoring systems for assessing this disability, one of which is MIDAS; the Migraine Disability Assessment Score. The objective of our study was to determine the extent of disability among migraine patients, patterns of prophylaxis, and their healthcare-seeking behaviors.MethodsThis survey was done in 50 migraine patients at Jinnah postgraduate medical Centre from April to May 2018. The questionnaire inquired about the demographic information, management of migraine, and effect of this condition on their sleep, and the last part had assessment to know about their functional disability.ResultsThe majority of the patients were females with a mean age of 31 ± 10 years. Acetaminophen was the most common medication used during a migraine attack, followed by nonsteroidal anti-inflammatory drugs. Only 54% of subjects admitted using prophylaxis, out of which 94% had stopped taking it after some time, with the most common reason being their side effects. β-blockers were the most common prophylaxis used. Only 32% had a regular follow-up visit with their doctors. Patients were graded according to the MIDAS score as: little or no disability, 22%; mild disability, 14%; moderate disability, 24%; and severe disability, 40%.ConclusionsThe majority of migraine patients were found to have severe disability, which affected their daily work and social activities. Despite an increase in disability rate due to migraine, people do not seek regular medical care for this type of headache in Pakistan.

The objective of this study was to detect if cardiopulmonary bypass time duration has any impact on the duration of postoperative mechanical ventilation (MV). The study design was a systematic review and regression analysis of pooled data from previously published studies. All available data are from prospective, retrospective, cross-sectional, and observational studies. Participants included only patient/human studies. There were no interventions. PubMed and Cochrane libraries were searched by utilizing different combinations of keywords: cardiopulmonary bypass and mechanical ventilation. Inclusion criteria were: (1) English articles, (2) studies with an adult population that underwent cardiac surgeries using cardiopulmonary bypass (CPB), (3) studies where the duration of CPB is provided as well as the duration of mechanical ventilation. A regression analysis was performed on the metadata.For the hours of MV, eight studies with 13 data sets (as some studies provide data in subgroups) were included for a total number of 989 subjects. The duration of CPB ranged from 55 to 173.5 minutes for these operations. Postoperative MV hours ranged from nine to 408 hours. Stepwise multiple regression analysis found that cardiopulmonary bypass time (CPBT), age, diabetes, male gender, and ejection fraction correlated with prolonged mechanical ventilation; CPBT was the most strongly correlated variable. Cardiopulmonary bypass time appears to affect clinical outcomes adversely and is associated with prolonged MV. Avoiding CPB or limiting it to a minimum may decrease the days of MV required.

AimSeveral factors determine the perioperative outcome besides the nature of the congenital heart defect. Prolonged mechanical ventilation (PMV) is a major factor that determines mortality, length of stay (LOS), residual disability, and other functional outcomes. We aim to determine the clinical variables predicting PMV and LOS in hospital, and specifically the impact from the duration of cardiopulmonary bypass (CPB) and aortic cross-clamp (ACC).MethodWe conducted a retrospective review of the medical records of 413 children consecutively admitted to the Pediatric Cardiac Intensive Care Unit (PCICU) in one year at a single center. We collected demographic information (e.g., age, gender, and weight), perioperative variables, clinical outcomes, length of mechanical ventilation, high-frequency ventilator use, and mortality. We used logistic regression to analyze the data. PMV was defined as mechanical ventilation for longer than seven days.ResultsA total of 410 records were included in our study. We found no statistically significant association between CPB time and mechanical ventilation days. Forty-seven children had PMV, 362 did not have PMV. We found no statistically significant association between CPB time and mechanical ventilation days after adjusting for covariates. Reanalyzing the data with PMV defined as longer than four days produced the same results. Using a regression model to assess the variables via the least absolute shrinkage and selection operator for feature selection, we found no statistically significant association between ACC time and mechanical ventilation days after adjusting for covariates.ConclusionAccording to our results, CPB and ACC time are not associated with PMV or prolonged hospital LOS.

Objective-To compare by cross sectional study the quantitative heel ultrasound (QUS) variables broadband ultrasound attenuation (BUA) and velocity of sound (VOS) in male powerlifters and controls. Methods-Twenty four powerlifters and 21 sedentary male controls were recruited to the study. All the powerlifters were members of the British Drug Free Powerlifting Association and actively competing at the time of the study. A questionnaire was completed by all those entered into the study. This included a history of smoking and an estimation of daily intake of alcohol and calcium. For the powerlifters, the number of years spent training and time spent training each week was also recorded. The QUS variables of all powerlifters and controls were measured using a Cubaclinical II (McCue) ultrasound scanner. Results-The powerlifters had been training for a mean (SEM) of 10.6 (1.6) years and they trained for 6.5 (0.4) hours a week. The powerlifters were non-significantly older and had a significantly higher body mass index (BMI) than the controls. Calcium intake and consumption of alcohol and tobacco were similar in the two groups. The mean BUA in the powerlifters was a significant 9.5% (95% confidence interval 0.7 to 18.3%) higher than the controls (105 v 96 dB/MHZ) and 15.6% (95% confidence interval 6.8 to 24.4%) higher after adjustment using analysis of covariance for age, BMI, and alcohol and tobacco consumption (108 v 93 dB/MHZ). The mean VOS was similar in the two groups, but after adjustment it was significantly higher in the powerlifters (1671 v 1651 m/s, p<0.01). Conclusions-The study shows the ability of heel ultrasound to discriminate between QUS variables in powerlifters and controls. The results indicate that the QUS variables BUA and VOS are significantly higher for powerlifters than for controls. (Br J Sports Med 2001;35:274-275)

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease affecting multiple systems by the process of inflammation and formation of auto-antibodies. When it presents in childhood, it is referred to as childhood systemic lupus erythematosus (cSLE). Cardiac tamponade is a rare but potentially lethal complication of cSLE, even rarer as an initial presentation. Sub-acute cardiac tamponade (medical tamponade) is a non-emergent type of cardiac tamponade which develops slowly over time and does not necessarily present with acute distress.We present the case of an 11-year-old girl who presented to the emergency department with complaints of intermittent fever, periorbital puffiness, abdominal distension, and swelling on the hands and feet. She was not in any acute distress but was vitally unstable. Cardiovascular examination revealed muffled heart sounds. Chest examination further revealed decreased breathing sounds on the left side with dull notes on percussion. Abdominal examination revealed positive shifting dullness with a distended abdomen.Blood investigations were ordered which revealed anemia and thrombocytopenia. Chest X-ray showed an enlarged cardiac silhouette. Urine detailed report showed proteinuria and hematuria. Further investigations revealed the autoimmune root of the disease. Echocardiography was ordered which showed a large collection of fluid around the posterior aspect of heart with the concomitant collapse of atrial chambers suggestive of cardiac tamponade. A diagnosis of sub-acute cardiac tamponade secondary to childhood SLE was made. The patient was started on pulse therapy of methylprednisolone followed by a low-dose regime of mycophenolate mofetil. The patient was also provided with positive pressure ventilation, hemodialysis, and invasive cardiovascular monitoring along with the instillation of intravenous fluid supplements. To our knowledge, cases of sub-acute cardiac tamponade as the only and early clinical manifestation in childhood SLE are very rare.
