OBJECTIVETo assess the therapeutic results of open reduction and internal fixation with crossed K-wires via lateral approach for displaced supracondylar fractures of the humerus in children.

METHODSWe prospectively followed 52 children who presented with Gartland type 3 displaced supracondylar fractures of the humerus and were managed by open reduction and internal fixation with crossed K-wires via lateral approach.There were 37 male and 15 female patients; average age was 7.39 years. The most common mechanism of trauma was fall while playing (n=23), followed by fall from height (n=20), road traffic accidents (n=5) and fall from standing height (n=2). In 2 cases, mode of injury was not available. The mean follow-up was 12 months and patients were assessed according to Flynn's criteria.

RESULTSLateral approach provided an excellent view of the lateral column between two nervous planes and enabled an anatomical reduction in all cases. Immobilizing the elbow at 90 degrees or more of flexion was not needed after cross K-wire fixation. Majority of patients regained full range of motion within 6 weeks of pin removal. Two patients had postoperative ulnar nerve injuries that resolved after pin removal. The common late complication of cubitus varus was not seen in any patient. Delayed presentation to the emergency department, repeated manipulations by bone setters and massage with edible oil were responsible for stiffness in 5 patients. Superficial pin tract infection was noted in 5 patients that resolved with dressings and antibiotics. No deep infection occurred. A detailed clinical examination and radiographic analysis was done at final follow-up. They included measurement of carrying angle and range of movements of both operated and normal sides, and radiographs of both upper limbs for comparison. According to Flynn's criteria, 90.4% patients showed satisfactory results.

CONCLUSIONLateral approach for open reduction and internal fixation of the widely-displaced supracondylar fracture of the humerus is safe and straightforward, ensuring anatomical reduction and excellent function. The approach is easy and familiar to most orthopedic surgeons in our setup.

PURPOSERubber bullets are considered a non-lethal method of crowd control and are being used over the world. However the literature regarding the pattern and management of these injuries is scarce for the forensic pathologist as well as for the traumatologist. The objective of this report was to add our experience to the existing literature.

METHODSFrom June 2008 to August 2010 the Government Hospital for Bone and Joint Surgery Barzulla and the Department of Orthopaedics, SKIMS Medical College/Hospital Bemina Srinagar received 28 patients for management of their orthopaedic injuries caused by rubber bullets. We documented all injuries and also recorded the management issues and complications that we encountered.

RESULTSAll patients weremales with an age range of 11e32 years and were civilians who had been hit by rubber bullets fired by the police and the paramilitary forces. Among them, 19 patients had injuries of the lower limbs and 9 patients had injuries of the upper limbs. All patients were received within 6 h of being shot.

CONCLUSIONOur findings suggest that these weapons are capable of causing significant injuries including fractures and it is important for the surgeon to be well versed with the management of such injuries especially in areas of unrest. The report is also supportive of the opinion that these weapons are lethal and should hence be reclassified.

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.

Transcranial direct current stimulation (tDCS) is a noninvasive method that may increase the rehabilitation effects in stroke. The objective of the study was to test whether tDCS priming with training on an arm ergometer boosts motor performance in chronic stroke patients. Three chronic subcortical stroke patients had continued a sole unilateral stroke 30–36 months formerly. They had some voluntary control of the arm in the affected side underwent a cycling training on an arm ergometer for 20 minutes a day, during 5 days a week priming with cathodal tDCS stimulation of unaffected hemisphere. They were tested during 4 sessions 1 week before, at the beginning, at the end, and 1 week after the end of the training priming with tDCS. We executed; 1) Rivermead Motorik Assessment (global function, arm and leg), 2) the Modified Ashworth Scale of the elbow flexors and extensors, 3) the minimum torque on the lesion side, 4) grip strength, and 5) pegboard performance at each time of testing the patients. All patients tolerated tDCS very well during experiment. Patients showed significant (p = 0.01) improved of force and spasticity (p = 0.03). The grip strength and pegboard performance improved significantly too after DCS priming with training. These results showed that cathodal tDCS is a useful device for rehabilitation when priming with motor training in stroke patients. These patients proved the clinical relevance of the results.

Wild cotton species can contribute a valuable gene pool for agronomically desirable cultivated tetraploid cultivars. In order to exploit diploid cotton a regeneration system is required to achieve transformation based goals. The present studies aimed at optimizing the conditions for regeneration of local varieties as well as wild species of cotton. Different callus induction media were tested with varying concentrations of hormones in which sucrose was used as nutritional source. Different explants (hypocotyls, cotyledon, root) were used to check the regeneration of both local cotton plants and wild relatives using T & G medium, BAP medium, CIM medium, EMMS medium, and cell suspension medium. Different stages of embryogenicity such as early torpedo stage, late torpedo stage, heart stage, globular stage and cotyledonary stage were observed in wild relatives of cotton. The results of this study pave the way for establishing future transformation methods.

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.

Objective: The study examined the efficacy of various generations of cephalosporins against biofilms developed by pathogenic S. aureus and E. coli. Methods: The development of biofilms by both bacteria was assessed using petri-plate and microplate methods. Biofilm hydrolysis and inhibition were tested using first to fourth generations of cephalosporins, and the effects were analyzed by crystal violet staining and phase contrast microscopy. Results: Both bacterial strains exhibited well-developed biofilms in petri-plate and microplate assays. Cefradine (first generation) showed 76.78% hydrolysis of S. aureus biofilm, while significant hydrolysis (59.86%) of E. coli biofilm was observed by cefipime (fourth generation). Similarly, cefuroxime, cefadroxil, cefepime, and cefradine caused 78.8%, 71.63%, 70.63%, and 70.51% inhibition of the S. aureus biofilms, respectively. In the case of E. coli, maximum biofilm inhibition (66.47%) was again shown by cefepime. All generations of cephalosporins were more effective against S. aureus than E. coli, which was confirmed by phase contrast microscopy. Conclusions and Relevance: Cephalosporins exhibit dual capabilities of hydrolyzing and inhibiting S. aureus and E. coli biofilms. First-generation cephalosporins exhibited the highest inhibitory activity against S. aureus, while the third and fourth generations significantly inhibited E. coli biofilms. This study highlights the importance of tailored antibiotic strategies based on the biofilm characteristics of specific bacterial strains.

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.
