In healthy subjects, the majority of PTH is secreted in tonic fashion, whereas approximately 30% is secreted in low-amplitude and high-frequency bursts occurring every 10-20 min, superimposed on tonic secretion. Changes in the ultradian PTH secretion were shown to occur in patients with primary and secondary osteoporosis, with skeletal effects depending on the reciprocal modifications of pulsatile and tonic components. Indeed, pathophysiology of spontaneous PTH secretion remains an area potentially suitable to be explored, particularly in those conditions such as secondary forms of osteoporosis, in which conventional biochemical and densitometric parameters may not always give reliable diagnostic and therapeutic indications. This review will highlight the literature data supporting the hypothesis that changes of ultradian PTH secretion may be correlated with skeletal fragility in primary and secondary osteoporosis.展开更多

Patients and Methods: We conducted a descriptive cross-sectional study of bladder tumours over the period from 1 April 2012 to 1 April 2017, in the urology department of the Nianankoro Fomba Hospital in Segou. The first three years were used for patient recruitment, and the last two years for follow-up of the patients in the series. Results: Over a period of three years, we collected 165 cases of bladder tumours hospitalised out of 1308 hospitalisations from 7007 consultations, i.e. 12.6% of hospitalisations and 2.3% of consultations. The sex ratio was 1.2 in favour of men. A history of treated bilharzia was reported in 78.8% of cases and untreated bilharzia in 9.1% of cases. Haematuria was the most common reason for consultation. The majority of our patients were at stage T4 and T3 at the time of diagnosis, i.e. 53.3% and 44.3% respectively. Most patients consulted within 13 to 24 months after the first sign, i.e. 44.8%. Conclusion: The prognosis is still clouded by the delay in management. All the patients diagnosed had a bladder tumour infiltrating the muscle.展开更多

The main treatment method of almost all skin cancers and subcutaneous tissue tumours is surgery, which consists of complete removal of a neoplastic lesion, with an adequate margin of healthy tissue. Radiotherapy plays an adjuvant role in this process, meaning complementing of the surgical procedure. This study compared four methods of irradiation treatment of cancer located in the skin or in subcutaneous tissues: contact brachytherapy, conventional orthovoltage therapy, electron beam conformal teleradiotherapy and IMRT dynamically shaped photonic beams conformal teleradiotherapy. In order to compare the methods and techniques of surface radiotherapy, following specific objectives were formulated. At the beginning in order to compare the scopes of the absorbed doses at different tissue depths, an analysis of parameters describing particular beams or radiation source has been performed—the curves for the absorbed-dose depth drop-offs. Doses distribution in tissue-like phantoms stimulating homogeneous cuboidal tissue block has been determined. A quality comparison of dose distribution in 2D and 3D treatment planning system for contact brachytherapy application has been made. The dose distribution for electron beam in the system has been determined. Conformal plannings for electron beam treatment, contact brachytherapy applicator treatment and 4 photon beams treatment optimized in IMRT technology have been performed. Dose distribution has been performed for the irradiated female patient within the well chest—the target included the recurrence area in the post-operative scar. The radiation therapy with X-rays has actually been completely eliminated from skin cancer and subcutaneous tissue radiotherapy by the electrons generated in linear accelerators, contact brachytherapy HDR and by high-energy photons used in conformal techniques, ex. IMRT. It is because the residual dose beyond the target is the highest for single X-ray beam. Although in brachytherapy HDR a rapid dose drop-off is observed, 5 cm from its normalization level for the target the residual radiation remains at the level of several percent. So, both X-rays beam radiation and brachytherapy in skin cancer treatment is connected with the administration of the dose with a high gradient in the health tissues. The dose distribution for photon conformal techniques IMRT or for electron radiation looks different. There with the dose normalization at the level of 90% or 85% we deal with the dose layer, the division does not exceed 15% of heterogeneity.展开更多

During this period, we operated on 73 patients for acute appendicitis, including 51 men and 22 women, for a sex ratio of 1.7. The average age was 25.5 with extremes of 1 and 40 years. Abdominal pain was the main reason for consultation. The physical signs were dominated by the positivity of the Blumberg sign in 97.3% of the cases, the defense of the right iliac fossa in 79.5%, and the Rovsing sign in 61.6% of the cases. This physical examination made it possible to make the diagnosis in the majority of cases. In the face of some doubtful cases, we requested an abdominal ultrasound. Locoregional anesthesia was the most used anesthesia technique at 72.6%. The classic anterograde appendectomy with stump burial by Mac Burney was the most commonly used technique, respectively. The postoperative consequences were straightforward in 87.6%. Anatomopathology examination was performed on 69 surgical specimens and 4 appendectomy specimens were not subjected to an anatomo-pathological examination. Phlegmonous appendicitis was the most common at 63% of cases. Appendicitis remains the most common surgical emergency in a community setting. The early diagnosis and the speed of treatment guarantee improvements in the prognosis. The treatment is mainly surgical.展开更多
