“I Can’t Wait for You to Die”

Stemming from conflicts over the authority of professional archives to arrange and steward community knowledge, this article outlines the limitations of the archival apparatus to produce the conditions for social liberation through acquisition and offers suggestions for how to operate otherwise, as a collaborator in forgetting. It discusses the origins and revised mission of the Pittsburgh Queer History Project (PQHP) as a reflection of the precarious definition of community archives within the discipline and field of archival science. By retracing the steps in the PQHP’s mission, as it moved from being a custodial and exhibit-focused collecting project to acting as a decentralized mobile preservation service, I argue that community archival practice is an important standpoint from which to critically reassess the capacity of institutional archives to create a more conscious and complete history through broader collecting. Specifically, I demonstrate how contemporary attention to the value of community records and community archives is frequently accompanied by a demand for such archives, records, and communities to confess precarity and submit to institutional recordkeeping practices.

Identification, Prevention and Treatment of Drug Toxicity in the Primary Care Settings

Studies from global countries indicate that poisoning is a common etiology for morbidities and associated mortality. Most of the cases did not require medical intervention as they were treated at home. However, around one-fourth required management at a healthcare facility. In addition to the healthcare burdens, evidence indicates that these events also have significant economic burdens on the affected patients and healthcare facilities. The present literature review provided evidence regarding the proper ways to identify patients presenting with suspected medication poisoning and the recommended management approaches. Obtaining a complete history from the patient should be the first step that can lead to diagnostic clues. Then, a thorough examination should be provided, followed by relevant imaging and laboratory studies to confirm the diagnosis. Management might be supportive in many cases, and an antidote can enhance the treatment process. Approaches should also be conducted to achieve decontamination and enhance the elimination of the affected patients.

Aortic complications in pregnancy: the less remembered chapter—a narrative review

Pregnancy increases the risk of common vascular events and also the rarer events like aortic dissection (AD)/aortic rupture and this is even more pronounced in patients with predisposing aortopathies. AD was found to occur in 0.0004% of all pregnancies, and it is more pronounced in patients with underlying connective tissue disorders. The normal hemodynamic changes on a weak aorta will lead to AD and/or rupture, more so with increase in the period of gestation. Hence the haemodynamic and hormonal changes during pregnancy make pregnancy itself a risk factor for AD. It is advised that women with Marfan syndrome who are planning pregnancy should go through prophylactic aortic repair if the diameter of the ascending aorta exceeds 4 cm. Pre-pregnancy counselling is very important in these patients and must include complete history taking, including family history, physical examination and advanced aortic imaging. There is a general consensus among various authors advising against surgery during pregnancy in stable patients due to increased maternal and fetal morbidity but it is justified if the condition is refractory to medical management or in life threatening stage like acute AD. Though the incidence of aortopathy in pregnancy is rare, there is a high maternal and fetal mortality associated with this condition.

A fast and oblivious matrix compression algorithm for Volterra integral operators

The numerical solution of dynamical systems with memory requires the efficient evaluation of Volterra integral operators in an evolutionary manner. After appropriate discretization, the basic problem can be represented as a matrix-vector product with a lower diagonal but densely populated matrix. For typical applications, like fractional diffusion or large-scale dynamical systems with delay, the memory cost for storing the matrix approximations and complete history of the data then becomes prohibitive for an accurate numerical approximation. For Volterra integral operators of convolution type, the fast and oblivious convolution quadrature method of Schädle, Lopez-Fernandez, and Lubich resolves this issue and allows to compute the discretized evaluation with N time steps in $O(N \log N)$ O ( N log N ) complexity and only requires $O(\log N)$ O ( log N ) active memory to store a compressed version of the complete history of the data. We will show that this algorithm can be interpreted as an ${{\mathscr{H}}}$ H -matrix approximation of the underlying integral operator. A further improvement can thus be achieved, in principle, by resorting to ${{\mathscr{H}}}^{2}$ H 2 -matrix compression techniques. Following this idea, we formulate a variant of the ${{\mathscr{H}}}^{2}$ H 2 -matrix-vector product for discretized Volterra integral operators that can be performed in an evolutionary and oblivious manner and requires only O(N) operations and $O(\log N)$ O ( log N ) active memory. In addition to the acceleration, more general asymptotically smooth kernels can be treated and the algorithm does not require a priori knowledge of the number of time steps. The efficiency of the proposed method is demonstrated by application to some typical test problems.

Coming to Know and Knowing Differently: Implications of Educational Leadership

Our paper will examine the question of counter-hegemonic knowledge production in the Western academy and the responsibilities of the Racialized scholar coming to know and producing knowing to challenge the particularity of Western science knowledge that masquerades as universal knowledge in academia. We engage the topic from a stance examining the coloniality of knowledge in educational leadership by centering Indigenous knowledge systems in the academy as a means to disrupt Euro-colonial hegemonic knowledging. We ask: How do we challenge the “grammar of coloniality” of Western knowledge and affirm the possibilities of a reimagining of “new geographies” and cartographies of knowledge as varied and intersecting ontologies and epistemologies that inform our human condition as “learning experiences, research, and knowledge generation” practices? The paper highlights epistemic possibilities of multicentricity, that is, multiple ways of knowledge as critical to understanding the complete history of ideas and events that have shaped and continue to shape human growth and development. The paper highlights Indigeneity as a salient entry point to producing counter-hegemonic knowing. The paper concludes pointing to implications for educational “re-search” and African educational futurity.

Temporomandibular joint disorders in children and adolescent: A review

Temporomandibular disorders (TMD) are a group of joint and muscular dysfunctions affecting the Cranio-orofacial area. Historically, TMDs were once believed to solely affect adults; however, recent studies have discovered an increased prevalence of TMD signs and symptoms in children and adolescents. The reported prevalence of these disorders in pediatric patients varies significantly due to methodological variations among studies; as a result, standardized diagnostic criteria for children are required. In this age group, TMDs can cause pain in the masticatory muscles and TMJs, as well as limited or asymmetric mouth opening and TMJ sounds. Rather than a single causative element, TMDs are produced by a combination of factors such as trauma, occlusion, systemic and developmental problems, and psychological disorders. A complete history and examination, which may include imaging, are essential to obtain a precise diagnosis and assure successful treatment of many disorders. For these issues, there is a range of therapeutic interventions available, although reversible treatments should be favored.

Should electronic differential diagnosis support be used early or late in the diagnostic process? A multicentre experimental study of Isabel

BackgroundDiagnostic errors unfortunately remain common. Electronic differential diagnostic support (EDS) systems may help, but it is unclear when and how they ought to be integrated into the diagnostic process.ObjectiveTo explore how much EDS improves diagnostic accuracy, and whether EDS should be used early or late in the diagnostic process.Setting6 Canadian medical schools. A volunteer sample of 67 medical students, 62 residents in internal medicine or emergency medicine, and 61 practising internists or emergency medicine physicians were recruited in May through June 2020.InterventionParticipants were randomised to make use of EDS either early (after the chief complaint) or late (after the complete history and physical is available) in the diagnostic process while solving each of 16 written cases. For each case, we measured the number of diagnoses proposed in the differential diagnosis and how often the correct diagnosis was present within the differential.ResultsEDS increased the number of diagnostic hypotheses by 2.32 (95% CI 2.10 to 2.49) when used early in the process and 0.89 (95% CI 0.69 to 1.10) when used late in the process (both p<0.001). Both early and late use of EDS increased the likelihood of the correct diagnosis being present in the differential (7% and 8%, respectively, both p<0.001). Whereas early use increased the number of diagnostic hypotheses (most notably for students and residents), late use increased the likelihood of the correct diagnosis being present in the differential regardless of one’s experience level.Conclusions and relevanceEDS increased the number of diagnostic hypotheses and the likelihood of the correct diagnosis appearing in the differential, and these effects persisted irrespective of whether EDS was used early or late in the diagnostic process.

Challenges in Diagnosis and Therapy of Recurrent Oral Herpes Infection: Study of Two Cases

The symptoms of recurrent oral herpes infection may vary, from mild discomfort to life threatening. Dentists are more likely to be consulted in this oral infection, hence the ability to diagnose and treat this disease is mandatory. This article described manifestation and therapy of recurrent oral herpes infection. In the first case, a 41-year-old woman came with a complaint of painful sore mouth in her lower gingiva. She experienced canker sores for two to three times a year on the tongue, lips and palate. Laboratory results showed positive IgM anti HSV-2, which matched with the primary herpes infection. However, based on the history and clinical manifestations, she was diagnosed with recurrent intra oral herpes infection. In the second case, a 70-year-old man came with a very painful canker sores in his entire mouth. The patient had to be hospitalised for three days and received analgesic, antibiotic and gel containing triamcinolone. After hospitalisation, canker sores did not heal. Extraorally, we found a crust in the vermillion border of the upper lip and intraorally, we found multiple ulceration of keratinised and non-keratinised mucosa. The use of topical steroid in this patient may aggravated ulceration due to its ability to cause rapid spreading of the virus. The first patient was given chlorhexidine gluconate 0.2% and the second patient was prescribed with doxycycline rinse. Both patients received multivitamin containing zinc. Complete history taking, objective and adjunctive examination played a role in establishing the diagnosis and treatment of recurrent oral herpes infections.

Comparative study of laparoscopic cholecystectomy with and without drains

Background: Gallstones and cholecystitis are very common pathologies in surgical practice. Laparoscopic cholecystectomy (LC) is the preferred procedure to remove the gallbladder (GB) worldwide. The main objective of this study was to evaluate the merits and demerits of placing drain after LC and to find out the clinico-pathologic conditions in which the placement of drain was justifiable.Methods: 100 patients who underwent LC were divided into 2 groups, group A (patients with drain) and group B (patients without drain). Interventional type, single-blind study was done. Complete history, evaluation and relevant data of both groups were done and analysed using descriptive statistics and Chi square test.Results: In group A, 44% were males and 56% females whereas in group B, 42% were males and 58% were females. There was a statistically significant difference (p value<0.05) between 2 groups in Visual analog scale (VAS) grading. Wound infection was seen in 14% in group A and 02% in group B; mean hospital stay in group A was 8.38±1.86 days and in group B was 4.68±1.25 days. Nausea and vomiting were noted in 46% among group A and 04 % among group B.Conclusions: Placement of drain after LC has nothing to offer, in contrast, it was associated with more pain. It would be reasonable to leave a drain if there was worry about an unsolved or potential bile leak only.
