Acute myocarditis related to Covid-19 infection: 2 cases report.

INTRODUCTION AND IMPORTANCE: Since COVID 19 was described for the first time in December 2019, we have not stopped discovering its different clinical manifestations. Despite the respiratory complication which is the most common symptomatology, multi-organ dysfunction and multiple cardiovascular complications were described such as acute myocarditis, heart failure and even arrhythmias. CASES PRESENTATION: Two patients aged 26 and 56 year-old, developed acute myocarditis related to Covid-19 infection but with different symptomatology. CASE 1: Presented to the emergency room with digestive symptomatology, Covid-19 infection was confirmed by a positive chest CT scan and positive COVID-19 serology testing. Clinical, biological, radiological findings allowed making the diagnosis of a Covid-19 infection with a bacterial superinfection complicated by a fulminant myocarditis. CASE 2: Presented to the emergency department with a chest pain, dyspnoea, paroxistic cough, myalgia and fever. A Covid-19 infection was confirmed. The electrocardiogram showed a diffuse ST elevation, echocardiography showed normal systolic function and the high-sensitivity cardiac troponin I level was high. Invasive coronary angiography was performed, revealing angiographically normal coronary arteries. CLINICAL DISCUSSION: Our 2 cases were treated differently, case 1 received antibiotherapy because of the bacterial superinfection and inotropic support for the septic and cardiogenic choc. Contrarily to case 2 who received inotropic support, immunoglobulin and corticosteroid. With a total recovery for both patients. CONCLUSION: This article can help in considering cardiac affection due to SARS-CoV2, even with poor respiratory symptomatology, and to insist on the importance of the cardiac evaluation for young patients with a sever Covid-19 infection.

Patent foramen oval: A rare case of acute ischemia of the upper limb: A case with 2 year follow-up.

INTRODUCTION AND IMPORTANCE: Paradoxical emboli (PDE) represent less than 2% of all arterial emboli, that is why they are considered as a rare event. We notice that the upper limb ischemia is very exceptional as part of a paradoxical embolism. This case presentation can help in considering the diagnosis the PFO as one of the most important risk factors of paradoxical embolism. CASE PRESENTATION: Here, we present a rare case of a 69-year-old woman with paradoxical systemic arterial embolism, presented by an acute ischemia of the upper limb, secondary to deep venous thrombosis and pulmonary embolism in the presence of patent foramen ovale, treated with long-term anticoagulation with rivaroxiban 20 mg/day, because of the mutation of the Factor II whish indicate already the anticoagulation. DISCUSSION: Echocardiographic techniques such as transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), or transcranial echocardiography (TCE) are the principal tools used to detect PFO. There are no clear consensus on the treatment of PDE. Presenting symptoms largely depend upon the location of the embolus, necessitating a different approach for each patient, but There is essentially three therapeutic options: surgical embolectomy, thrombolysis, and anticoagulation. CONCLUSION: PFO closure is, today, a standardized and safe intervention, but the indication stay individualized to each patient.

Uremic pericarditis in patients with End Stage Renal Disease: Prevalence, symptoms and outcome in 2017.

The prevalence of uremic pericarditis (UP) used to range from 3% to 41%. More recently, it has decreased to about 5%-20% and to <5% in the last decades, as hemodialysis techniques have become widely used and dialysis quality improved. The objective of this work is to determine the initial clinical picture and the prognosis of patients presenting End Stage Renal Disease (ESRD) with UP. MATERIALS: This is a retrospective study (May 2015-September 2017). Inclusion criteria targeted patients who had uremic pericarditis defined as pericarditis occurring in a patient with ESRD before initiation of renal replacement therapy, or within eight weeks of its initiation. RESULTS: 16 patients met the inclusion criteria. The median age of patients was 54 [24, 71] years and 56.2% were male. Pericardial effusion was small, moderate and large in 31.2%, 37.6% and 31.2% of cases respectively. One pericardiocentesis was performed in view of a clinical picture of impending cardiac tamponade and three pericardial drainages were performed given presentation of tamponade. Hemodialysis was initiated for all the patients and continued for 2 to 3weeks until complete regression of the pericardial effusion. The mean number of dialysis sessions was 11±3.5. One patient died of septic shock that developed three weeks after diagnosis of uremic pericarditis. CONCLUSION: UP is considered a rare but fatal complication of ESRD because of the risk of tamponade and its prognosis remains dependent on early diagnosis and adequate treatment of ESRD.

Infective endocarditis in chronic hemodialysis: A transition from left heart to right heart.

Infective endocarditis (IE) of the left heart is the most frequent type of IE in chronic hemodialysis (CHD) (in 90% of cases) whereas involvement of the right heart is rare. The aim of this study was to determine the clinical, biological, and echocardiographic characteristics, as well as the prognosis of IE in CHD. This is a retrospective study conducted at the Center of Nephrology and Hemodialysis in Oujda, Morocco. Over a period of 56 months, we compiled data on a series of 11 CHD patients with IE. Their mean age was 40.5 ± 14 years, 72% were male and 27.3% had diabetes. All patients had native valve. All patients had bacteremia preceding the episode of IE. The tricuspid valve was the site of IE in 45% of the cases. Cardiac complications were observed in 72% of the patients and mortality was observed in 72% of cases. The period from IE diagnosis to death was 9 ± 6 days. In our study, the tricuspid valve was the most affected valve of IE in CHD.

A survival case in a severe amlodipine intoxication.

Calcium channel blockers (CCBs) are prescribed in a wide variety of cardiovascular conditions. Nevertheless, they remain a major cause of cardiovascular drug overdose that often leads to a lethal outcome. We report the case of an intoxication with amlodipine, which caused severe hypotension, in a young woman. The patient was initially treated with fluids, calcium gluconate, and Dobutamine without effect. She then received hyperinsulinemia euglycemia therapy. A rise in blood pressure (BP) was observed two hours after insulin was started. The next day, the insulin infusion was stopped and seven days later the patient was discharged from the hospital after psychiatric consultation. The positive inotropic effect of insulin therapy in our patient supports previous findings that suggest its use as a first-line therapy in the management of CCBs overdose.

Chorea-ballismus in acute non-ketotic hyperglycaemia.

Diabetic patients during hyperglycaemic crises may present a rare syndrome characterised by a typical triad: unilateral involuntary movements (hemichoreahemiballism), radiological contralateral striatal abnormality, and rapid resolution of symptoms after glycae - mic correction. This study reports a series of patients showing less usual aspects and also discusses the pathophysiology of this clinical-radiological syndrome. We included in this study four patients presenting choreic or ballic involuntary movements and in whom aetiological assessment revealed frank non-ketotic hyperglycaemia, without other abnormalities that could explain the movement disorder. All the patients underwent CT or MR brain imaging. The typical triad was present in only one case. Less classical aspects were more frequently found: movement disorders revealed diabetes in two patients and one patient had generalised chorea and strictly normal neuroimaging. Correction of blood glucose was not sufficient to improve symptoms in two cases. In one, abnormal movements persisted despite treatment with tetrabenazine. The clinical, radiological and outcome spectrum of the syndrome of chorea-ballismus induced by non-ketotic hyperglycaemia is heterogeneous and not restricted to a typical triad.

[Recurrent pneumothorax revealing a tuberous sclerosis complex]. / Sclérose tubéreuse de Bourneville révélée par des pneumothorax à répétition.

Tuberous sclerosis complex (TSC) is an autosomal dominant phacomatosis. We report a 29-year-old woman who presented with recurrent pneumothorax in whom the diagnosis of TSC relied on the existence of family history (child with cardiac rhabdomyome), skin lesions, pulmonary lymphangiomyomatosis, hepatic lipomas, renal angiomyolipomas, uterine myomas and cerebral lesions on MRI. The diagnostic of TSC might be difficult as it could mimic pulmonary lymphangiomyomatosis.

[Bilateral idiopathic orbital myositis]. / Myosite orbitaire idiopathique bilatérale.

INTRODUCTION: Orbital myositis is an idiopathic inflammation of the extraoccular muscles. It is often included under the broad description of orbital pseudotumor. It is commonly a unilateral affection. CASE REPORT: We report one case of bilateral orbital myositis in a 45-year-old woman. The first symptoms were diplopia and acute bilateral orbital pain exacerbated by eye movements. Physical examination especially neurological was normal. Serum creatine kinase and biological thyroid function were normal. CT scan found a bilateral enlargement of rectus oculi medialis and lateralis. Clinical improvement was obtained a few days after oral corticosteroid treatment with remission of all signs. CONCLUSION: Orbital myositis is a rare entity. 90-95p.cent of cases are unilateral. Bilateral forms are exceptional and in this case require search for specific etiologies particularly thyroid ophthalmopathy. There is controversy concerning treatment options but corticosteroids are still the most common first choice therapy with good outcome.
