Exploring the landscape of symptom-specific inflammatory cytokines in post-COVID syndrome patients.

Introduction: Post-COVID syndrome (PCS) is characterized by a polymorphism of symptoms with hypothetical pathophysiological mechanisms. Here, we aimed to analyze the profile of inflammatory cytokines in patients with PCS and to study the relationship between this profile, the clinical symptoms as well as the endothelial function in PCS.

Methods: Our analytical study involved all eligible patients (n = 66) with PCS included from April 2021 to December 2021.

Aetiology of Vascular Purpura in a Single Centre Experience: Contribution of Clinical and Paraclinical Data.

Background: Vascular purpura can be the clinical expression of infectious, inflammatory, drug-related, neoplastic, and endocrine pathologies. To date, there is no consensus codifying the investigation of vascular purpura, especially when it is isolated.

Patients And Methods: We proposed to study through a retrospective study of 73 cases of vascular purpura, occurring during the period 2004-2019 in our internal medicine department, the contribution of various clinical and paraclinical data to the aetiological diagnosis of vascular purpura.

Yellow urticaria revealing overlap syndrome of autoimmune hepatitis and primary biliary cholangitis.

Yellow urticaria is a variant of urticaria that is rarely reported in the literature. It usually occurs in the setting of a chronic liver disease and reflects the accumulation of bilirubin in the skin tissues. We report a case of yellow urticaria that occurred in a 33-year-old female patient suffering from systemic lupus erythematosus and overlap syndrome of autoimmune hepatitis and primary biliary cholangitis revealed by a migratory pruritic yellowish urticarial eruption on the trunk and limbs.

Recurrences and bleeding during extended treatment of patients with venous thromboembolism: results of the international, prospective, observational WHITE study.

Background: Little data are available on real-life long-term treatments after a venous thromboembolism (VTE), and on recurrent VTE or bleeds events during treatments.

Methods: We investigated the complications occurring during follow-up (FU) in VTE patients who had received the treatment decisions given by the clinical centers, active in 7 countries (China, Czechia, Poland, Portugal, Russia, Slovakia, Tunisia), which participated in the international, prospective, observational WHITE study.

Results: FU information was collected in 1004 patients, recruited by 62 clinical centers (17 centers did not participate in FU collection).

Flagellate dermatitis: An atypical skin finding in adult-onset Still's disease.

A 23-year-old woman followed for adult-onset Still's disease (AOSD) presented fever and chest pain. Clinical examination showed erythematous papules suggestive of flagellate dermatitis. Laboratory findings showed increased Cardiac troponin.

Sulodexide Significantly Improves Endothelial Dysfunction and Alleviates Chest Pain and Palpitations in Patients With Long-COVID-19: Insights From TUN-EndCOV Study.

Objective: Non-respiratory long-coronavirus disease 2019 (COVID-19) symptoms are mainly related to a long-lasting endothelial dysfunction and microcirculation impairment. We hypothesized that Sulodexide, a purified glycosaminoglycan mixture with a beneficial endothelial effect in arterial and venous peripheral diseases, may be effective in a subset of patients with long COVID-19.

Approach And Results: We conducted a multicenter prospective quasi-experimental study.

Long COVID 19 Syndrome: Is It Related to Microcirculation and Endothelial Dysfunction? Insights From TUN-EndCOV Study.

The COVID-19 disease is a multisystem disease due in part to the vascular endothelium injury. Lasting effects and long-term sequelae could persist after the infection and may be due to persistent endothelial dysfunction. Our study focused on the evaluation of endothelial quality index (EQI) by finger thermal monitoring with E4 diagnosis Polymath in a large cohort of long COVID-19 patients to determine whether long-covid 19 symptoms are associated with endothelial dysfunction.

Anticoagulation Duration After First Venous Thromboembolism: Real-Life Data From the International, Observational WHITE Study.

Background: International guidelines recommend at least three months anticoagulation in all patients after acute venous thromboembolism (VTE) and suggest those with unprovoked events be considered for indefinite anticoagulation if the risk of recurrence is high and the risk of bleeding during treatment non-high. Other authors have recently argued against using a dichotomy unprovoked/provoked events to decide on anticoagulation duration and suggest instead using overall risk factors present in each patient as the basis for deciding.

Aim: This sub-analysis of the WHITE study aimed at assessing the reasons for the treatment decisions taken by doctors in different countries.

Unprovoked or provoked venous thromboembolism: not the prevalent criterion to decide on anticoagulation extension in clinical practice of various countries-the prospective, international, observational WHITE study.

The decision on treatment after a first venous thromboembolism (VTE) to prevent recurrences may be influenced by many factors. The prospective, observational, WHITE study aimed to analyze how this issue was tackled in every-day clinical practice in various countries, which have sensibly different socio-economic conditions and healthcare systems. Doctors active in 79 Internal or Vascular clinical centers in 7 countries (China, Czechia, Poland, Portugal, Russia, Slovakia, and Tunisia) enrolled VTE patients after the maintenance treatment phase.

[A rare cause of pulmonary arterial hypertension: Thoracic amyloidosis].

Isolated thoracic involvement in amyloidosis is a rare and serious condition. Its association with pulmonary arterial hypertension (PAH) usually weakens the prognosis. We report the case of a 40-year-old man with a smoking history, hospitalized for chest pain, abdominal pain and acute respiratory distress.

Pheochromocytoma presenting as an authentic small vessel vasculitis and complicated with pulmonary embolism: An original presentation.

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.

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

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.

Young ischemic stroke in Tunisia: a multicentric study.

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

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.

Prevalence and risk factor of renal dysfunction induced by bacterial infection other than spontaneous bacterial peritonitis in patients with cirrhosis.

Background: Deterioration of renal function in cirrhotic patients with spontaneous bacterial peritonitis (SBP) is a predictor for inhospital mortality. However, the clinical significance of renal dysfunction during bacterial infection other than SBP is unknown.

Aim: To investigate the prevalence and clinical significance of renal dysfunction due to bacterial infections other than SBP in patients with liver cirrhosis.

Malignant epithelioid hemangioendothelioma: a case report.

Malignant epithelioid hemangioendothelioma (EH) is a rare tumor of vascular origin. We report a case of a woman who was found to have multiple hepatic masses in the right lobe of the liver on radiologic investigations, initially misdiagnosed as a metastatic carcinoma. The diagnosis of EH was made on histopathological study and confirmed by immunohistochemistry, which showed diffuse response for CD34 marker and no response to tissue CEA, HMB-45 or S-100 protein.

Predictive factors of morbidity after surgical treatment of hepatic hydatid cyst.

Introduction: Surgery remains the basic treatment of hepatic hydatid cyst (HHC). However, it is associated with significant morbidity. The aim of our study was to evaluate mortality and morbidity of surgery of the HHC and to highlight the risk factors.

[Recurrence of hydatid cyst of liver: predictive factors: Tunisian experience].

Cystic echinococcosis is a public health problem. Surgery represents the basic treatment and the surgeon is regularly faced with the choice of the appropriate surgical procedure (radical versus conservative surgical approach). The conservative procedure is safe and easy but can lead to a recurrence in the site of residual cavity.
