Right atrial thrombus, junctional tachycardia, and critical lower limb ischemia: three rare complications of severe acute respiratory syndrome coronavirus 2 infection

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can engender multi-system inflammatory syndrome. Its main symptoms are cardiovascular and thromboembolic problems that can develop into severe complications. The present case is about a 55-year-old patient who was admitted for critical ischemia of the right lower limb and necrosis of the right forefoot. The patient was infected with coronavirus disease 2019 (COVID-19) one month before her admission. The patient also has cardiovascular risks including type 2 diabetes and hypertension. The performance of ultrasounds revealed a thrombus in the right atrium and the pulmonary artery, and arteriography detected an occlusion of the right popliteal joint for which she had an endovascular recanalization and amputation of the right forefoot. This case highlights that SARS-CoV-2 infection could be considered a serious cardiovascular disease requiring cardiovascular explorations to initiate hospital management and avoid severe complications

Will Africans take COVID-19 vaccination?

The economic and humanistic impact of COVID-19 pandemic is enormous globally. No definitive treatment exists, hence accelerated development and approval of COVID-19 vaccines, offers a unique opportunity for COVID-19 prevention and control. Vaccine hesitancy may limit the success of vaccine distribution in Africa, therefore we assessed the potentials for coronavirus vaccine hesitancy and its determinants among Africans. An online crosssectional African-wide survey was administered in Arabic, English, and French languages. Questions on demographics, self-reported health status, vaccine literacy, knowledge and perception on vaccines, past experience, behavior, infection risk, willingness to receive and affordability of the SARS-COV-2 vaccine were asked. Data were subjected to descriptive and inferential statistics. A total of 5,416 individuals completed the survey. Approximately, 94% were residents of 34 African countries while the other Africans live in the Diaspora. Only 63% of all participants surveyed were willing to receive the COVID-19 vaccination as soon as possible and 79% were worried about its side effects. Thirty-nine percent expressed concerns of vaccine-associated infection. The odds of vaccine hesitancy was 0.28 (95% CI: 0.22, 0.30) among those who believed their risk of infection was very high, compared to those who believed otherwise. The odds of vaccine hesitancy was one-fifth (OR = 0.21, 95% CI: 0.16, 0.28) among those who believed their risk of falling sick was very high, compared to those who believed their risk of falling very sick was very low. The OR of vaccine hesitancy was 2.72 (95% CI: 2.24, 3.31) among those who have previously refused a vaccine for themselves or their child compared to counterparts with no self-reported history of vaccine hesitancy. Participants want the vaccines to be mandatory (40%), provided free of charge (78%) and distributed in homes and offices (44%). COVID-19 vaccine hesitancy is substantial among Africans based on perceived risk of coronavirus infection and past experiences.http://www.plosone.orgam2022Veterinary Tropical Disease

les anévrismes géants de l’artère splénique à propos de 6 cas

Les anévrysmes de l’artère splénique sont rares, les anévrysmes géants de plus de 10 cm sont extrêmement rares et représentent le troisième site des anévrysmes intra abdominaux et la première localisation des artères digestives Nous rapportons six cas colligés au service de la chirurgie vasculaire « D » complétés par une revue de la littérature. L’étiopathogénie n’est pas encore bien établie, la dysplasie fibromusculaire artérielle systémiques, l’hypertension portale et la grossesse semblent contribuer à l’apparition et à l’évolution de ces anévrysmes. La majorité des anévrysmes de l’artère splénique sont asymptomatiques, cependant les anévrysmes de l’artère splénique peuvent se manifester par des douleurs épigastriques ou de la partie supérieure de l’hypochondre gauche. La radiographie abdominale sans préparation, l’échographie, l’angioscanner, l’imagerie par résonnance magnétique et l’artériographie peuvent être pratiqués et cette dernière reste l’examen de référence. Le traitement chirurgical dépend du site anévrysmal (proximal ou distal) et du type d’intervention élective ou urgente. Les anévrysmes de l’artère splénique peuvent être traités par embolisation, cependant plusieurs complications peuvent se voir suite au traitement par embolisation

Pseudoaneurysm of the subclavian artery following clavicle fracture due to blunt traumatism: a case report

The clavicle fractures are frequent, vascularinjuries associated with closed fractures of clavicleare rare. The pseudoaneurysms of the subclavianartery constitute an exceptional complication. Wereport a case of a 40-year-old who presented anexpanding hematoma of the right side of the neckafter a road traffic accident. Radiography of theright shoulder showed a midclavicular fracture. Anarterial doppler of vessels showed a circulatinghematoma in the contact of the right subclavianartery with a correct distality flow. Computedtomographic angiogram of the chest confirmed thediagnosis of a false aneurysm in the postvertebralportion of the right subclavian artery. Thetreatment was surgical and consisted of excision ofthe false aneurysm and a repair of the arterialinjury by an arterial patch, the clavicle was fixedwith a reconstruction plate and screws. Earlyintervention appears to be indicated due to the riskof thrombo-embolic complications. Endovascularrepair appears to be the preferred treatmentmodalities, due to a lower rate of cardiopulmonarycomplications, but it is reserved for much selectedcases

Redetermination of catena-poly[[chloridolead(II)]-μ2-chlorido-di-μ2-thiourea-κ4S:S] at 100 K

Although the structure rerefinement (CCD data at 100 K) of the polymeric lead(II) thiourea complex, [PbCl2·2tu]n where (tu = SCN2H4), basically confirmed the previous study based on integrated Weissenberg data recorded at room temperature [Nardelli & Fava (1959). Acta Cryst. 12, 727–732]; all atomic positions could be determined with significantly higher precision and accuracy. In addition, all H atoms could be located from difference maps, revealing details of the hydrogen-bonding scheme
