Study of anxiety-depressive disorders among doctors at "Salah Azaïez" Cancer Institute in Tunis.

INTRODUCTION: Oncologists are often confronted with patients at the end of their lives who are suffering. This can lead to anxiety and depressive disorders (ADD), affecting the quality of the doctors's quality of life. AIM: To compare the level of ADD among doctors practicing at Salah Azaiez Institute (SAI) in Tunis with doctors who do not treat cancer patients, while identifying any factors associated with these disorders. METHODS: We conducted a comparative and analytical study of 141 physicians:53 oncologists practicing at the Salah Institut Azaiez and 91 at other hospital structures (Charles Nicolle's Hospital and Rabta's Hospital), matched by age and gender for a period of 2 months, started from 02 May to 30 June 2022. RESULTS: Our research showed that SAI's doctors were significantly more exposed to anxiety disorders (p= 0.016) compared with other doctors (47.2% vs. 37.5%), without being more exposed to depressive disorders. SAI's doctors reported more associated stress factors, notably exposure to body image-distorting tumors (p<0.001), exposure to the suffering of loved ones (p=0.006), lack of human resources (p=0.017), perceived unsuitability of premises (p=0.001) and overwork (p=0.013). These doctors consumed more alcohol (p=0.04). In addition, 58.5% of SAI's doctors felt that their profession significantly affected their quality of life, compared to 45% of doctors in other hospitals (p=0.04). CONCLUSIONS: All the doctors questioned, "all specialties combined", showed varying rates of anxiety and depressive disorders. However, anxiety disorders were significantly higher among SAI's doctors, for whom stress factors had a greater impact.

Femoral Head Stress Fracture in Children: A Case Report.

INTRODUCTION: The stress fracture of the femoral head rarely occurs; but, it is generally encountered in case of bone insufficiency, and it is exceptional in younger individuals. The main differential diagnosis may include several diseases, namely, slipped upper femoral epiphysis, septic arthritis, osteomyelitis, and Perthes' disease. Bone scintigraphy is very sensitive but lacks specificity. Nowadays, the magnetic resonance imaging (MRI) is the gold standard for an accurate diagnosis. CASE REPORT: We present the first description of this pathology in the pediatric population with the particularity of its atypical aspect on MRI through a case of stress fracture of femoral head in 12-year-old female. CONCLUSION: Stress fractures may sometimes mimic malignant or infectious lesions and are easily misdiagnosed. MRI is the gold standard which may be the only modality to identify the fracture.

The bone scintigraphy in the diagnosis and management in children with febrile osteoarticular pain.

BACKGROUND: Bone and joint infections are common diseases in pediatrics. They still are a public health problem in Tunisia. The diagnosis is based on clinical, biological, radiological and skeletal scintigraphy arguments. The purpose of this study is to determine the contribution of triple phase bone scan in the exploration of musculoskeletal pain febrile child. METHODS: This was a descriptive and retrospective study. It was conducted over a period of 5 years. It has interested all children explored in nuclear medicine department with suspected acute osteomyelitis (OMA) , osteoarthritis (OA) or septic arthritis (SA) referred from Orthopaedic Infantile service. All these patients had, alongside the conventional radiologic exams, a triple phase bone scan HMDP-Tc99m. RESULTS: We collected 62 patients. Among the selected diagnoses, there were: 22 OMA, 4 OA, 4 SA. The mean age of the patients was 5.58 years with a male predominance. The main reason for consultation was pain. Fever was ≥ 38° C in 80 % of cases. The preferential localization was the lower limb (93.5 %). The quantitative and qualitative bone scan abnormalities objectified led to a correct diagnosis of: 18 OMA, 3 OA and 2 SA with a respectively estimated sensitivity and specificity of 76.6% and 90.6% in the all population. CONCLUSIONS: Bone scan demonstrates early abnormalities allowing osteoaricular infection diagnosis. It highlights the infection site, and draws a map of the lesions. Currently, imaging modalities differ in their availability, their cost, their input and diagnostic accuracy but they are complementary.

[The value of multimodal imaging by single photon emission computed tomography associated to X ray computed tomography (SPECT-CT) in the management of differentiated thyroid carcinoma: about 156 cases]. / Place de l'imagerie multimodale par tomoscintigraphie couplée au scanner dans la prise en charge des cancers différenciés de la thyroïde: étude sur 156 cas.

BACKGROUND: Single photon emission computed tomography combined with a low dose computed tomography (SPECT-CT), is a hybrid imaging integrating functional and anatomical data. The purpose of our study was to evaluate the contribution of the SPECTCT over traditional planar imaging of patients with differentiated thyroid carcinoma (DTC). METHODS: Post therapy 131IWhole body scan followed by SPECTCT of the neck and thorax, were performed in 156 patients with DTC. RESULTS: Among these 156 patients followed for a predominantly papillary, the use of fusion imaging SPECT-CT compared to conventional planar imaging allowed us to correct our therapeutic approach in 26.9 % (42/156 patients), according to the protocols of therapeutic management of our institute. CONCLUSION: SPECT-CT is a multimodal imaging providing better identification and more accurate anatomic localization of the foci of radioiodine uptake with impact on therapeutic management.

Improvement of early 18F-FDG PET interpretation in diffuse large B-cell lymphoma: importance of the reference background.

UNLABELLED: This study investigated whether the reference background above which a residual mass is considered positive in the International Harmonization Project criteria should be modified for early (18)F-FDG PET evaluation. METHODS: In 92 patients with newly diagnosed diffuse large B-cell lymphoma, the maximal standardized uptake value (SUVmax) was measured on post-cycle 2 PET in the most intense residual mass (or, in the case of negative PET findings, in the area of most intense tumor uptake before therapy), in the mediastinal blood pool (MBP) and the liver, as potential reference background tissues. RESULTS: With MBP as a reference (SUVmax, 2.0 ± 0.6), PET was unable to distinguish early responders from nonresponders. In contrast, with liver as a reference (SUVmax, 2.5 ± 0.7), 2-y progression-free survival was significantly different between patients with PET-negative findings (81.8% [95% confidence interval, 71%-93%]) and patients with PET-positive findings (51.8% [95% confidence interval, 35%-69%], P = 0.003). CONCLUSION: When assessing early response, particularly in risk-adapted therapeutic trials, it seems preferable to refer to a background tissue (liver) with a higher level of uptake than that of current international criteria (MBP) which were designed for end-of-treatment evaluation.
