BACKGROUND: Pakistan has been hugely struck with massive bomb explosions (car and suicide bombs) resulting in multiple casualties in the past few years. The aim of this study is to present the patterns of skeletal and soft tissue injuries and to review the outcome of the victims who presented to our hospital. METHODS: This is a retrospective chart review from January 2008 to December 2012. The medical record numbers of patients were obtained from the hospital Health Information and Management Sciences (HIMS) as per the ICD-9 coding. RESULTS: During the study period, more than 100 suicide and implanted bomb blast attacks took place in the public proceedings, government offices, residential areas and other places of the city. Altogether 262 patients were enrolled in the study. The mean age of the patients was 31±14 years. The shrapnel inflicted wounds were present on to the upper limb in 24 patients and the lower limb in 50. CONCLUSION: Long bone fractures were the most common skeletal injuries. The fractures were complicated by penetrating fragments and nails which result in post operative infections and prolonged hospital stay.

STUDY DESIGN: Cross sectional study. PURPOSE: The purpose of this study was to determine the incidence and the associated risk factors of pinhole type of durotomy and cerebrospinal fluid (CSF) leakage following a simple laminectomy for spinal stenosis. OVERVIEW OF LITERATURE: The incidence of spinal stenosis is expected to rise with increasing life expectancy. Moreover, lumbar spinal stenosis is the most common indication for spinal injury in the geriatric population. It is therefore important to identify and prevent the risks associated with laminectomy, the most widely used surgical procedure for spinal stenosis. The serious complication of incidental dural tear or durotomy and subsequent CSF leakage has not been studied in the region of Southeast Asia. METHODS: In this cross sectional study, we included 138 adult patients (age>18 years), who underwent a simple laminectomy for lumbar stenosis between 2011 and 2012. CSF leakage was the main outcome variable. Patients' wounds were examined for CSF leakage up to 1 week postoperatively. RESULTS: The incidence of pinhole type durotomy and subsequent CSF leakage in our region was 8.7%. Univariate analysis showed that hypertension, diabetes and smoking were significantly associated with durotomy and increased CSF leakage by 16.72, 44.25, and 33.71 times, respectively. Multivariate analysis showed that only smoking and diabetes significantly increased the chances of leakage. CONCLUSIONS: Glycemic control and cessation of smoking prior to a simple laminectomy procedure reduced the incidence of a dural tear. Larger clinical studies on this lethal complication are required.

The coronavirus disease 2019 (COVID-19) pandemic rapidly spread globally. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19, is a positive-sense single-stranded RNA virus with a reported fatality rate ranging from 1% to 7%, and people with immune-compromised conditions, children, and older adults are particularly vulnerable. Respiratory failure and cytokine storm-induced multiple organ failure are the major causes of death. This article highlights the innate and adaptive immune mechanisms of host cells activated in response to SARS-CoV-2 infection and possible therapeutic approaches against COVID-19. Some potential drugs proven to be effective for other viral diseases are under clinical trials now for use against COVID-19. Examples include inhibitors of RNA-dependent RNA polymerase (remdesivir, favipiravir, ribavirin), viral protein synthesis (ivermectin, lopinavir/ritonavir), and fusion of the viral membrane with host cells (chloroquine, hydroxychloroquine, nitazoxanide, and umifenovir). This article also presents the intellectual groundwork for the ongoing development of vaccines in preclinical and clinical trials, explaining potential candidates (live attenuated-whole virus vaccines, inactivated vaccines, subunit vaccines, DNA-based vaccines, protein-based vaccines, nanoparticle-based vaccines, virus-like particles and mRNA-based vaccines). Designing and developing an effective vaccine (both prophylactic and therapeutic) would be a long-term solution and the most effective way to eliminate the COVID-19 pandemic.

We assessed the efficacy of frozen-thawed gelatin-induced osteogenic cell sheet (FT-GCS) compared to that of fresh gelatin-induced osteogenic cell sheet (F-GCS) with adipose-derived mesenchymal stromal cells (Ad-MSCs) used as the control. The bone differentiation capacity of GCS has already been studied. On that basis, the experiment was conducted to determine ease of use of GCS in the clinic. In vitro evaluation of F-GCS showed 3–4 layers with an abundant extracellular matrix (ECM) formation; however, cryopreservation resulted in a reduction of FT-GCS layers to 2–3 layers. Cellular viabilities of F-GCS and FT-GCS did not vary significantly. Moreover, there was no significant difference in mRNA expressions of Runx2, β-catenin, OPN, and BMP-7 between F-GCS and FT-GCS. In an in vivo experiment, both legs of six dogs with transverse radial fractures were randomly assigned to one of three groups: F-GCS, FT-GCS, or control. Fracture sites were wrapped with the respective cell sheets and fixed with 2.7 mm locking plates and six screws. At 8 weeks after the operations, bone samples were collected and subjected to micro computed tomography and histopathological examination. External volumes of callus as a portion of the total bone volume in control, F-GCS, and FT-GCS groups were 49.6%, 45.3%, and 41.9%, respectively. The histopathological assessment showed that both F-GCS and FT-GCS groups exhibited significantly (p < 0.05) well-organized, mature bone with peripheral cartilage at the fracture site compared to that of the control group. Based on our results, we infer that the cryopreservation process did not significantly affect the osteogenic ability of gelatin-induced cell sheets.

Canine babesiosis is an important tick-borne protozoal disease of dogs that poses major health problem worldwide. Farm dogs in rural areas are the companion animals, that not only watch the livestock herds but also guard the house of the owners. Each farmer keeps his companion dog to get all the services. In our study, a total of 450 blood samples of farm dogs from three different ecological zones (Southern, Central and Northern regions of the province; Punjab) of Pakistan, were collected to examine through microscopy and PCR. Examination of thin blood smears revealed an overall prevalence of 12.8% (58/450) of canine babesisal parasites. However, PCR analysis revealed 46.8% (211/450) and 7.3% (33/450) samples positive for B. gibsoni and B. vogeli, respectively. The amplicons of 671 bp and 590 bp were amplified for the detection of B. gibsoni and B. vogeli, respectively through PCR. The results of multivariate analysis showed that the occurrence of canine babesiosis is higher in the Central Punjab and younger age of the dogs, while breed and sex of the host were not significantly associated with the occurrence of the disease. Mixed infection of B. gibsoni and B. vogeli was observed only in 3 dogs each in district Kasur and Rawalpindi. Our study is the first report to observe the occurrence of canine babesiosis in rural dogs in Pakistan through PCR.
