Caseous calcification of the mitral annulus (CCMA) is a rare echocardiographic finding. It is commonly misdiagnosed as an abscess, tumor or infective vegetation on the mitral valve. Since it is a benign process, differentiating it from malignant intra-cardiac mass is primordial to avoid unnecessary surgery. Various imaging modalities can be complimentary for definitive diagnosis. We present a case of CCMA in a 71-year-old female patient. Her medical history revealed hypertension, diabetes mellitus, hyperlipidaemia and coronary artery disease. She was referred to our department for coronary catheterization because of angina symptoms upon minimal exertion. The lesion was detected during echocardiography and was defined as a mass of heterogeneous content with calcification points, located at the posterior side of the mitral valve annulus. Restricted motion of the posterior leaflet and the mass effect caused only minimal mitral regurgitation. To establish the correct diagnosis, we performed the full spectrum of noninvasive cardiac imaging modalities. Transesophageal echocardiography identified well-organized, composite lesion with regular edges, markedly calcified margins and more echolucent central portion. A computed tomography (CT) was performed, showing a hyperdense mass with hypodense center and a calcified peripheral rim located at the posterior mitral ring. Cardiac magnetic resonance imaging (MRI) showed that the mass was hypointense with respect to the myocardium in the T1 and T2-weighted sequences and only presented late-phase enhancement in the surrounding capsule. Based on the CT and MRI findings, the diagnosis of CCMA was established. The patient was managed conservatively.
Although pericarditis is the most prevalent cardiac involvement in systemic lupus erythematosus (SLE), cardiac tamponade is extremely infrequent notably as the first manifestation of the disease. Here we report the case of a 22-year-old woman presenting with cardiac tamponade as the initial presentation of SLE.
Introduction. Although epirubicin has significantly improved outcome in breast cancer (BC) patients, it is responsible for myocardial dysfunction that affects patients’ quality of life. The use of 2D global longitudinal strain (GLS) has been reported to detect early myocardial dysfunction. The aim of this study was to evaluate how GLS changes can predict cardiotoxicity. Methods. We conducted a prospective study from March 2018 to March 2020 on 66 patients with no cardiovascular risk factors, who presented with BC and received epirubicin. We measured left ventricular ejection fraction (LVEF) and GLS before chemotherapy, at three months (T3), and at 12 months (T12) from the last epirubicin infusion. Chemotherapy-Related-Cardiac-Dysfunction (CTRCD) was defined as a decrease of 10% in LVEF to a value below 53% according to ASE and EACI 2014 expert consensus. Results. The mean age at diagnosis was 47 ± 9 years old. At baseline, median LVEF was 70% and median GLS was −21%. Shortly after chemotherapy completion, two patients presented with symptomatic heart failure while asymptomatic CTRCD was revealed in three other patients at T12. Three months after the last epirubicin infusion, median LVEF was 65%, median GLS was −19%, and median GLS variation was 5%. However, in patients who presented with subsequent CTRCD, median GLS at T3 was −16% and median GLS variation was 19% (

, respectively, when compared to patients who did not develop cardiotoxicity). Persistent GLS decrease at T3 was an independent predictor of CTRCD at T12. Age and left-sided thoracic irradiation did not increase the risk of cardiotoxicity in our study while the cumulative dose of epirubicin significantly affected cardiologic findings (

). Conclusion. This was the first North African study that assesses the value of measuring GLS to early detect cardiotoxicity. Patients whose GLS remained decreased after 3 months from anthracyclines-base chemotherapy had an increased risk for developing subsequent CTRCD. Further studies with larger sample size are warranted to identify the best cardioprotective molecules to be initiated in these patients before LVEF declines.
Background:
In conflict areas, orthopaedic surgeon adopted this concept of damage control orthopaedic (DCO) to face limb fracture due to ballistic trauma because of the gravity of the hurts, the limitation of equipment, and precarious conditions of asepsis. They use external fixation as an initial treatment at the nearest health centre. And they delay the definitive treatment to be realized in better conditions. Our study aims to assess the outcome of damage control orthopaedic (DCO) strategy in military ballistic limb trauma according to the experience of the Military Hospital of Tunisia.
Materials and methods:
This study is a retrospective study on patients who were hospitalized for a limb ballistic fracture. It includes military patients treated urgently with primary external fixation at the nearest health centre. We adapted Gustilo classification to describe the wound opening, Winquist and Hansen classification to define the fracture comminution and Grading system for bone loss to evaluate the bone loss. Then all victims were evacuated secondary, to the Military hospital to receive the definitive treatments. The conversion to internal osteosynthesis had taken place according to some criteria. They were the absence of local sepsis, a haemoglobin level (> 10 g/dl), a serum protein level (> 50 g/l) and a negative or falling CRP kinetics. We studied the delay of conversion from external fixation to an internal osteosynthesis, bone healing time and complications.
Result:
Our study included 32 patients, all men, mean age was 31 years. The average follows up was 33,2 months. 88% of trauma concerned lower limb. The average delay for conversion from external fixation to internal osteosynthesis was 7,8 days. The bone union was achieved in 26 cases, with an average delay of 4.23 months. Observed general complications were anaemia, pulmonary embolism and rhabdomyolysis. Local complications were essentially sepsis on osteosynthesis material and pseudarthrosis. These complications were significantly associated with a type III of Gustilo skin opening, a type III and IV of the Winquist fracture comminutions, a type II and III of the Grading system for bone loss, and the delay for conversion from external fixation to internal osteosynthesis.
Conclusion:
DCO is a global strategy which involves all measures participating in the acceleration of the wound healing and fighting against the infection. These measures shorten the delay of conversion from external fixation into an internal osteosynthesis, which constitutes a key parameter in the management of limb fracture due to ballistic trauma.
