Script concordance test as a sanctionnal evaluation in cardiology.

INTRODUCTION: Sanctioning evaluation in cardiology is carried out using multiple choice questions, short-answer questions, clinical cases and editorial questions. However, these methods do not assess clinical reasoning in a context of uncertainty in contrast with script concordance tests (SCT). AIM: To compare the scores obtained by the students in the 3rd year of medicine with the SCT versus the sanctioning test of cardiology and to study the correlation between these two evaluation methods. METHODS: This is a prospective study including 31 3rd year students who completed their cardiology clerckship in the Cardiology Department of the HabibThameur Hospital during the first half of 2016. We compared the scores obtained in the 13 SCT test (39 items) with those of the cardiology normative test. RESULTS: Students 'mean score at SCT was significantly lower than that of experts (66.6 ± 10.2 vs 86 ± 6.7%, p <0.0001). The mean score obtained by students at the SCT was significantly higher than that of the cardiology sanctioning test (p <0.001). Cronbach alpha coefficient was 0.71. There was no correlation between the two tests (r = 0.329; p= 0.07). CONCLUSION: The evaluation of our students by the SCT showed mean score statistically higher than the questions of a classic test, without correlation between them. This should encourage us to incorporate SCT into our assessment methods to promote clinical reasoning.

Epidural angiolipoma: A rare cause of spinal cord compression.

INTRODUCTION: Angiolipomas are benign, slow growing lesions, almost always located subcutaneously in the trunc or limbs. They are composed of mature lipocytes admixed with abnormal blood vessels. Spinal epidural angiolipoma are rare accounting for approximately 0.14-1.2% of all spinal axis tumors and 2-3% of epidural spinal tumors. PRESENTATION OF CASE: We report the case of a 65 years-old-woman, presenting with complete paraplegia installed since 7 months. Magnetic resonance imaging (MRI) showed an epidural dorsal fatty mass. The patient recovered immediately after surgery. The pathological examination concluded to an angiolipoma. DISCUSSION: Angiolipoma patients most commonly have long-lasting pain and then develop progressive neurological symptoms secondary to spinal cord compression. The mean duration of symptom progression at diagnosis is 1 year. MRI is the most reliable examination for the diagnosis of spinal angiolipoma. Total resection is the treatment of choice. No adjuvant treatment is indicated. Since SAL are very haemorrhagic lesions, preoperative embolization is recommended. CONCLUSION: We think that spinal cord compression caused by angiolipoma have very good functional prognosis, even if tardily diagnosed.

Floating Forearm with Terrible Triad Injury of the Elbow: A Case Report.

INTRODUCTION: Floating forearm is rare. Simultaneous terrible triad injury of the elbow is even rarer. CASE REPORT: A 47-year-old male patient presented with concurrent dorsal perilunate dislocation of the left wrist combined with a terrible triad injury of the left elbow after a fall from the second floor. The patient had an immediate reduction of the dislocated elbow. Then, a fixation of the radial head by screws, anterior capsule suture, and lateral collateral ligament repair was performed. The wrist dislocation was reduced and fixed with K-wires through a dorsal approach. At 12 months, the patient only complained of moderate pain on heavy lifting and had resumed his work. CONCLUSIONS: A perilunate dislocation of the wrist may occur simultaneously to a terrible triad injury of the elbow at the same side, especially in polytrauma patients. These patients should be examined carefully. An urgent surgical treatment has been successful, while severe damage to the function of the superior limb may result if the diagnosis is missed.

Unusual circumstances to diagnose cervical Pott's disease.

Tuberculous spondylodiscitis usually affects the dorso-lumbar spine, and its cervical location is a rare condition that can mimic other diseases and consequently cause treatment delays. We report a case of tuberculous spondylodiscitis of the lower cervical spine discovered under unusual circumstances in a patient with severe polytrauma involving a cranio-cerebral trauma, a non-displaced fracture of the two laminæ and the spinous process of the C6 vertebrae as well as fibular and tibial shaft fractures. The patient underwent static tibial nailing, and a collar with occipital and chin supports was applied. At 2-month follow-up, the patient presented with severe neck pain without neurologic deficits. Plain and dynamic cervical radiographs showed a stable C6-C7 subluxation and C7 superior endplate collapse. The CT scan also outlined prevertebral soft tissue swelling. The MRI showed a C6-C7 spondylodiscitis associated with a prevertebral abscess with am 8-cm major axis. The diagnosis of C6-C7 Pott's disease was confirmed by a CT-guided biopsy. The patient received 12 months of antituberculous chemotherapy, after which the paravertebral abscess completely disappeared, and the patient has had no functional sequelae. The diagnosis of cervical spine tuberculosis is difficult and requires a high level of attention. Delays in establishing the diagnosis and starting the appropriate treatment result in severe complications such as spinal cord compression and spinal deformity, which are difficult to manage.

An uncommon variant of the Essex-Lopresti injury.

The Essex-Lopresti injury is an extremely rare condition combining radial head or neck fracture, distal radio-ulnar joint dislocation and rupture of the interosseous membrane. However, there are rare or unusual varieties or associated injuries. We report a case of a 46-year-old woman with a posterior dislocation of the radio-humeral joint, a radial shaft fracture, and a distal radio-ulnar joint dislocation. She underwent open reduction and internal fixation of the radial shaft fracture followed by an immobilization by a long elbow splint in supination for 6 weeks. At 18 months of follow-up, she was asymptomatic and she had a full range of elbow and wrist motion and had resumed thoroughly her previous job. The Essex-Lopresti injury results from a complex injury to the forearm axis with resultant longitudinal instability, which can be challenging to treat. There are some variations that can lead to a missed diagnosis resulting in persistent pain and instability of the wrist. The best outcomes are reached with early diagnosis and prompt management.

Myxoid liposarcoma of the hand - A rare entity.

Hand liposarcomas are not well recognized in common practice, which leads to erroneous diagnostics and delayed proper treatment. We reported a case of a myxoid liposarcoma classified as stage IIb, and developed in the palmar side of the left hand in a 38-year-old man. There was an initial tumor reduction by a sclerosing agent injection that proved to be a failure. An open excisional biopsy confirmed the diagnostic after pathology examination. Recurrence occurred after 2 years, followed by a second resection and an adjunctive radiotherapy. At 5 years follow-up, the patient was recurrence free. Although myxoid liposarcoma is rare in the hand, it should be considered in the differential diagnosis of a painless soft tissue mass in this region.
