Temporary mechanical support in the peripartum patient as a bridge to postpartum recovery: A report of three cases.

Cardiogenic shock (CS) is a severe complication of peripartum cardiomyopathy (PPCM). Patients with deteriorating CS often require temporary mechanical circulatory support. In PPCM, this can be used as a bridge to postpartum recovery or bridge to decision. The outcomes are unclear, especially if prolonged utilization is required. We present a case series of three patients with PPCM in deteriorating CS who were successfully supported with a ventricular assist device or veno-arterial extracorporeal membrane oxygenation as a bridge to postpartum recovery.

Simulation training using cadaver sheep chest in pleuroscopy - A step towards skills enhancement.

OBJECTIVE: For assessing the use of if simulation training on animal cadavers as a useful tool for training in pleuroscopy. METHODS: The email-based cross-sectional study was conducted in December 2014 at Shaikh Zayed Hospital, Federal Postgraduate Medical Institute, Lahore, Pakistan, and comprised respiratory physicians and trainees after their participation in a two-day hands-on training course on pleuroscopy and pleural medical procedures. The responses were analysed and the responses of physicians and trainees were compared. RESULTS: Of the 44 individuals who attended the course and were contacted through emails, 38(86.4%) responded, including 20(52.6%) physicians and 18(47.3%) trainees. All the 38(100%) subjects uniformly accepted the utility of simulation training in enhancing education, improving skill, and improving confidence by repeated practice, and felt that the inclusion of animal models for learning fundamental pleuroscopic procedures can help a lot in teaching. CONCLUSIONS: Animal cadavers can be used as an effective teaching tool for pleuroscopy training.

Co-amplification of microbial DNA: A novel observation of a misconstrued second peak at locus D7S820.

DNA fingerprinting, a gold standard, is one of the most powerful tool in applied sciences especially helpful in criminal investigation. Entering in advanced era of forensic DNA, profile reading is much trickier than ever. An unusual DNA profile was observed from a nail swab of female brutally murdered in a domestic violence case. At first, DNA profile was misconstrued as heterozygote at locus D7S820 but later, it was confirmed as homozygous from other evidence items submitted in the same case. Subsequent reprocessing of the same sample, from the extraction stage through to DNA profiling and DNA profile form victim's blood, conclusively established that the unusual peak is from a non-specific microbial presence at that locus.

Lumbar Erector Spinae Plane Block for Total Hip Arthroplasty Comparing 24-Hour Opioid Requirements: A Randomized Controlled Study.

Design: Prospective, randomized, controlled trial. Patients. Sixty-three adult patients with an American Society of Anesthesiologists Status I-III who are undergoing elective primary total hip arthroplasty. Interventions. Patients were randomized to the control group (no block) or the ESPB group (preoperative ultrasound-guided lumbar ESPB). Intraoperatively, all patients received spinal anesthesia with moderate sedation. Postoperatively, patients received a standardized multimodal analgesia protocol. Measurements. The primary outcome was cumulative opioid consumption at 24 hours postoperatively. Secondary outcomes included cumulative opioid consumption at 8 hours and through 48 hours postoperatively and pain scores at 24 and 48 hours post surgery. Main Results. Thirty-one patients were randomized to the control group (spinal alone) and 32 patients to the ESPB group. The median opioid requirement in the first 8 hours after surgery was higher in the control group (28 mg of oral morphine equivalents (OME) versus 5 mg of OME in the ESPB group) (p = 0.013). There was no statistically significant difference in opioid consumption between the groups at 24 hours (p = 0.153) or 48 hours (p = 0.357) postoperatively. There was no statistically significant difference in pain scores between the two groups through 24 hours (p = 0.143) or 48 hours (p = 0.617) after surgery. Conclusion: Lumbar ESPB reduces opioid utilization during the first 8 hours postoperatively after total hip arthroplasty but not thereafter. Evaluating the use of either adding a local anesthetic adjunct to the ESPB or using longer-acting local anesthetic warrants further investigation.

Diversification of Pakistani Amelogenin-Y-Null Male Haplotypes.

Amelogenin is a common sex typing marker encountered in forensic case work. Phenotypically normal males have been reported in the literature who exhibit anomalous amelogenin allele. These males express only a single amelogenin peak representing AMEL-X and are called as AMEL-Y-null males. Gender misclassification of such individuals is an obvious consequence of this mutation, as a male sample would falsely appear to be a female sample. This study was aimed to attribute the AMEL-Y-null male DNA profiles encountered in forensic casework in the Pakistani population to appropriate phylogenetic clade based on shared ancestry. A total of 18 null AMEL-Y males were screened out of the sample pool of 5000 male individuals, reflecting mutational frequency of 0.36%. A common phylogenetic ancestor is suggested for 17 individuals, based on computational analysis of the Y-STR haplotypes, shown to be belonging to the J haplogroup while only one sample belonged to the R group. The samples in J groups showed homology with subclades J2b2a M241 and J2b2a PH1648, while R group individual showed 100% homology with R1a. Data are reported after haplotype network development of AMEL-Y-null Pakistani males using Network 10.0 for the study of evolutionary distances and emergence of nodes.

PFSA DNA database: A tool to hunt the serial offenders.

A forensic DNA database comprises of thousands of DNA profiles generated from suspects, convicts or even from common people from society. It is used for the cross-matching of DNA profiles obtained from evidence items collected from a crime scene. These databases are playing a core role in clearing the innocent and solving the dead-end unresolved crimes ultimately leading to crime reduction. In March, 2017, a nine years old minor girl was raped in district Khushab (Province Punjab). The medico-legal examiner indicated brutal sexual violence on the victim. Police apprehended a suspect who was excluded as the source of foreign male DNA from tested evidence items. Thus the case put up a question mark on the capabilities and efficiency of the police. An unknown male DNA profile obtained from evidence items was uploaded to PFSA DNA Database to maintain record. Later on, a suspect was arrested by Karachi (Province Sindh) police in another rape case, DNA profile of suspect was searched in the PFSA DNA Database. This generated DNA profile matched with the foreign DNA profile obtained from evidence items of minor victim, hence this atrocious crime was resolved. PFSA DNA Database provides support to criminal prosecution and also leads to identify potential suspects. It took years of effort to develop the rich PFSA DNA Database which subsequently proved to be fruitful in the exoneration of innocents and conviction of offenders in criminal cases.

Acute Psychosis with Recurrent Neurocysticercosis: A Case Presentation.

Description Neurocysticercosis, a parasitic infection of the central nervous system (CNS) caused by the Taenia solium cestode, presents clinically with a large and diverse spectrum of symptomatology, dependent upon lesion number, locale and ensuing inflammatory response. To this date, there are only two documented cases of psychosis presenting in patients with neurocysticercosis, both of which were published in India. This case presentation depicts the first documented case of Psychotic Disorder Due to Another Medical Condition: Neurocysticercosis in the United States. The authors postulate that the atypical presentation of the neuropsychiatric instability with the aberrant recurrence of neurocysticercosis is predominantly attributable to the parasitic infection itself, along with its resultant cyst formation and inflammatory response. Further research is necessary to expand upon our knowledge and understanding of the neuropsychiatric effects and optimal management of neurocysticercosis, as well as its possible recurrent nature.

Clinical and Demographic Characteristics Including Comorbidities and Their Outcomes Among Patients Hospitalized With COVID-19 in Four Tertiary Care Hospitals Across Lahore.

Background The first case of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was diagnosed in Wuhan, China, in 2019. By the first half of 2020, coronavirus disease 2019 (COVID-19) turned into a global pandemic. Objectives The aim of this study is to describe the clinical and demographic characteristics including comorbidities and their outcomes among patients hospitalized with COVID-19 in four tertiary care hospitals across Lahore. This retrospective study was conducted at Fatima Memorial Hospital, Sir Ganga Ram Hospital, Lahore General Hospital, and Jinnah Hospital, all in Lahore, Pakistan, from May 1, 2020, to June 30, 2020. The sample size was 445, which was derived using the convenient sampling method. Clinical outcomes during hospitalization included the requirement of invasive positive pressure ventilation, need for renal replacement therapy (RRT), and death. Data regarding demographics, baseline comorbidities, important vital signs on reporting, and initial workup with results were also collected. Results A total of 445 patients' data were studied, of whom 291 (65.4%) were male patients and 154 (34.6%) female patients. The median age was 54 years (interquartile range [IQR]: 24). The most common comorbidities were hypertension (HTN) (195; 43.8%) followed by diabetes mellitus (DM) (168; 37.8%) and cardiovascular disease (CVD) (61; 13.7%). The median length of hospital stay was eight days (IQR: 3). Of the total patients, 137 (30.7%) were treated in intensive care unit settings, 40 (9%) received invasive mechanical ventilation, 40 (9%) patients had acute kidney injury, 38 (8.5%) received RRT, and 37 (8.3%) died. It was seen that more patients who were either diabetic or hypertensive received invasive mechanical ventilation as compared to those who did not have these comorbidities. The most common radiological finding on chest X-ray was the classical ground-glass appearance of COVID-19, which was found in 318 (71.4%) patients. Conclusions Patients with one or more underlying comorbidities had poor clinical outcomes compared to those with no comorbidities, with the most vulnerable group being patients with chronic kidney disease, DM, HTN, and CVD in descending order.

Comparison of efficacy of dexamethasone and methylprednisolone in moderate to severe covid 19 disease.

BACKGROUND: The first case of Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were diagnosed in Wuhan, China in 2019. In the first half of 2020 this disease has already converted into a global pandemic. Various treatment options were being tried all over the world. Some studies showed beneficial effects of corticosteroids in covid 19. Hence, we designed this study to compare the effect of two steroids in moderate to severe covid 19 disease. OBJECTIVES: To compare the efficacy and safety of dexamethasone and methylprednisolone in moderate to severe covid 19 disease. STUDY SETTINGS: Fatima Memorial Hospital, Lahore and Ganga Ram hospital, Lahore. STUDY DESIGN: Quasi experimental, interventional study. DURATION OF STUDY: From 1st June 2020 to 30th June 2020. METHODOLOGY: Sample size and technique: there were total 100 patients; 35 patients received dexamethasone and 65 were kept in methylprednisolone receiving group. RESULTS: The mean age of patients was 57.91 years in dexamethasone group and 54.86 years in methylprednisolone group. In dexamethasone group, there were 15 (42.8%) critically ill patients who were shifted to Intensive care unit (ICU) and seven (20%) of them needed ventilatory support, whereas in methylprednisolone group 22 (33.8%) had to be admitted in ICU with eight (12.3%) patient needing ventilator. As outcome measure, patients in both the groups showed marked improvement in temperature, oxygen requirement and C-reactive protein (CRP) on day 5. Only six (17.1%) patient died who received dexamethasone while 10 (15.3%) patients died among those receiving methylprednisolone. CONCLUSION: Dexamethasone and methylprednisolone both are equally effective in treating moderate to severe covid 19 disease.

Dengue fever in Pakistan: a paradigm shift; changing epidemiology and clinical patterns.

Dengue fever has huge public health implications and affects over 100 million people worldwide. This review pictures the current situation of Dengue in Pakistan and presents a review of published literature. Pakistan has seen recurrent epidemics of Dengue Fever recently. Unfortunately, these epidemics are becoming more severe in their clinical manifestation. Pakistan experienced large epidemics of dengue fever during 2008, 2010 and 2011 affecting thousands of people and claiming hundreds of deaths. A comparison of data during these epidemics indicates a shift from mild to a more severe disease, which could be interpreted as an epidemiologic transition pattern in the country. Expansion of Dengue in Pakistan seems to be multifactorial, including the climate change, frequent natural disasters, vector resistance to insecticides and lack of resources. This highlights the need for rigorous vector control. Continuing education of primary care physicians is crucial for early appropriate management to reduce mortality.

A review on therapeutic potential of Nigella sativa: A miracle herb.

Nigella sativa (N. sativa) (Family Ranunculaceae) is a widely used medicinal plant throughout the world. It is very popular in various traditional systems of medicine like Unani and Tibb, Ayurveda and Siddha. Seeds and oil have a long history of folklore usage in various systems of medicines and food. The seeds of N. sativa have been widely used in the treatment of different diseases and ailments. In Islamic literature, it is considered as one of the greatest forms of healing medicine. It has been recommended for using on regular basis in Tibb-e-Nabwi (Prophetic Medicine). It has been widely used as antihypertensive, liver tonics, diuretics, digestive, anti-diarrheal, appetite stimulant, analgesics, anti-bacterial and in skin disorders. Extensive studies on N. sativa have been carried out by various researchers and a wide spectrum of its pharmacological actions have been explored which may include antidiabetic, anticancer, immunomodulator, analgesic, antimicrobial, anti-inflammatory, spasmolytic, bronchodilator, hepato-protective, renal protective, gastro-protective, antioxidant properties, etc. Due to its miraculous power of healing, N. sativa has got the place among the top ranked evidence based herbal medicines. This is also revealed that most of the therapeutic properties of this plant are due to the presence of thymoquinone which is major bioactive component of the essential oil. The present review is an effort to provide a detailed survey of the literature on scientific researches of pharmacognostical characteristics, chemical composition and pharmacological activities of the seeds of this plant.

Predicting inadequate spirometry technique and the use of FEV1/FEV3 as an alternative to FEV1/FVC for patients with mild cognitive impairment.

INTRODUCTION AND OBJECTIVES: Some patients cannot perform forced vital capacity (FVC). We conducted a study to answer three questions: Can the ability to perform components of spirometry be predicted by the Mini Mental State Examination (MMSE)? What proportion of subjects can perform forced expiratory volume in 3 s (FEV3) but not FVC? Does the forced expiratory volume in 1 s (FEV1)/FEV3 ratio concord with FEV1/FVC ratio in patients with airflow obstruction? METHODS: We conducted a prospective observational study of 267 patients with a mean age of 79 years, including subjects with indicators of frailty. They performed spirometry and the MMSE. Spirometric recordings were compared to the American Thoracic Society 1994 criteria. RESULTS: FVC was achieved by 51% of patients. Inability to perform FVC was predicted by an MMSE < 24 (specificity 94%, sensitivity of 51%). An FEV1/FEV3 ratio < 80% matched a FEV1/FVC ratio < 70% (sensitivity 96%, specificity 97%). Twenty-five percent of subjects were able to reach FEV3 but not FVC; 14% of that group had an MMSE < 24. Subjects with an MMSE < 20 were unable reliably to perform any spirometry. CONCLUSION: Patients with an MMSE < 24 are usually unable to reach FVC reliably when tested on a single occasion, but some can reach FEV3. Patients with MMSE < 20 cannot do spirometry. An FEV1/FEV3 ratio < 80% can be used to help identify patients with airflow obstruction if they are unable to perform full spirometry to FVC.
