Diagnosis of pheochromocytoma can be simple when classic manifestations are present. It can also be challenging and complicated in some cases because of its wide array of faces and presentations. We present a case of a 30-year-old female patient who came with acute respiratory distress, chest pain, hemoptysis, asthenia, anorexia, weight loss of 20kg, and paresthesia in her lower limbs. Clinical examination found high blood pressure, accelerated heart and respiratory rates, signs of acute right heart failure with jugular venous distention and ankle edema, reticularis livedo in the four limbs, ulcers in both knees and in the 3rd metacarpo-phalangeal articulations and necrotic lesions in both calcaneal tendons and in the right toes. Further investigations concluded on myocarditis associated with alveolar hemorrhage, pericardic and pleuritic effusions and a segmental pulmonary embolism of the right inferior lobe. Neuro-muscular biopsy was suggestive of myositis. Cutaneous biopsy found nonspecific chronic dermatitis. ANCA antibodies were tested twice and were negative. Cryoglobulinemia was also negative. Thoraco-abdomino-pelvic scan was performed showing a large right adrenal mass suggestive of pheochromocytoma. Diagnosis of right adrenal pheochromocytoma was confirmed by MIBG-I123 hyperfixation findings and urinary normetanephrin levels. The patient was treated surgically. Postoperative outcomes were remarkably favorable with a complete regression of the cutaneous lesions and normalization of the blood pressure. Paresthesia significantly decreased. Control echocardiography at 3 months showed an improved heart function with a persistent apical and septal akinesis.

[Characteristics of cardiac involvement in eosinophilic granulomatosis with polyangiitis].

Ann Cardiol Angeiol (Paris) 2021 Feb 23. Epub 2021 Feb 23.

Service de médecine interne, centre hospitalier universitaire Mongi-Slim, 2070 La Marsa, Tunisie.

Aim Of The Study: Our study aimed to identify the characteristics of cardiac involvement in eosinophilic granulomatosis with polyangiitis (EGPA).

Methods: We conducted a retrospective analytic study including EGPA cases diagnosed between 2000 and 2019 in an internal medicine department. Diagnosis was made according to the 1990 American College of Rheumatology criteria and the 2012 Chapel Hill Concensus.

Results: Eleven EGPA cases were included, 64% of patients were female. Median age at diagnosis was 52 years [42-58]. Heart damage revealed EGPA in 55% of cases with a significant predominance of women (p=0.015). The main cardiac manifestations were myocarditis, ischemic cardiomyopathy due to small vessel vasculitis, cardiac tamponade and intracardiac thrombus. Cardiac magnetic resonance imaging (MRI) mainly showed subendocardial hyposignal in early infusion and late enhancement in the same areas, nodular by locations, associated with impaired left ventricle function and micro-infarctions by distal vasculitis. Cardiac damage was associated to ANCA negativity in 83.3% of cases. The median Birmingham Vasculitis Activity Score version3 (BVAS v3) was 16 [10-17]. Under conventional treatment, no relapses had occurred. The median vasculitis damage index (VDI) was 2 [1-2.3] and the mortality rate was zero after a mean follow-up of 43 months.

Conclusion: Cardiomyopathy is a frequent revealing mode of EGPA. A late onset asthma and hypereosinophilia should guide the diagnosis. As ANCA research often turns out to be negative, histological evidence is recommended in this context. The contribution of cardiac MRI in the diagnosis of EGPA remains to be defined.

Young ischemic stroke in Tunisia: a multicentric study.

Int J Neurosci 2017 Apr 13;127(4):314-319. Epub 2016 Nov 13.

a Department of Internal Medicine, Mongi Slim Hospital , Tunis , Tunisia , and Faculty of Medicine of Tunis , Tunis El Manar University , Tunis , Tunisia.

Purpose: There is wanting data regarding young ischemic stroke in developing countries, especially in Tunisia. The purpose of this study was to investigate risk factors and etiologies of young ischemic stroke in Tunisian and make a comparison with previous reports.

Materials And Methods: A total of 102 young ischemic stroke patients (15-45 years old) were admitted, between January 1996 and August 2007, to 11 departments of internal medicine in different Tunisian hospitals. The risk factors for stroke were documented and assessed. Diagnosis workup consisted of anamnesis, complete physical examination and extensive laboratory, radiologic, immunologic, neurologic and cardiologic examination. Stroke etiologies were classified according the Trial of ORG 10172 in acute stroke treatment.

Results: There were 42 men (41.2%) and 60 women (58.89%) with a mean age at onset of 35.7 years. As regards stroke subtype, large-artery atherosclerosis was diagnosed in 6.9% of cases, cardioembolism in 11.8%, small-vessel occlusion in 8.8%, other determined etiology in 37.3% and undetermined etiology in 35.3%. Concerning the traditional risk factors, smoking (31.4%), hypertension and diabetes mellitus (12.7% for each one) and a family history of stroke (10.8%) were the most common. The mean follow-up period was 30.5 months.

Conclusions: In our study, traditional risk factors were not-so-uncommon in young adults with ischemic stroke suggesting that prevention can go through controlling these factors. Stroke of other determined etiology was the most common among our patients, so that a broad and detailed diagnostic workup is crucial to puzzle out the etiology for more and better stroke prevention.

The incidence of serious adverse events in a tunisian hospital: a retrospective medical record review study.

Tunis Med 2015 Dec;93(12):795-9

Aim: To describe the epidemiology of serious adverse events (SAE) reported in the division of internal medicine at the Mongi Slim university hospital in Tunis, to analyze their causes and contributing factors and compare them to that reported in literature so as to establish prevention strategies when these events were deemed preventable. Methods This retrospective study collected the medical records of randomly selected 500 index hospitalizations. Records review was conducted in two stages: a primary review that aimed to detect hospitalizations where a SAE was likely to have occurred then a secondary review which purpose was to confirm the presence of the SAE, to determine its nature and its preventability.

Results: SAE were detected in 5.2% of hospitalizations with a preventability of 57.7%. These events were responsible for a prolongation in 27.0% of hospitalizations and disability in 15.4% of cases. They were the cause of admission in 42.9% of hospitalizations in which a SAE occurred. The SAE consisted in adverse drug events in 73.0% of cases, healthcare-associated infections in 19.0% of cases, non-surgical procedures in 4% of cases and pressure ulcers in 4.0% of cases. Age and number of comorbidities were identified as the main risk factors for the occurrence of SAE.

Conclusion: Awareness of the extent and severity of the problem of iatrogenesis is necessary because it is a prerequisite to establishing a culture of patient safety among caregivers.
