Extent of surgery for differentiated thyroid cancer

The authors believe that total or near total thyroidectomy followed by 131I ablation and thyroid hormone suppression therapy are there commended extent of surgery and treatment of choice in differentiated thyroid cancer. This is based on retrospective data showing that total thyroidectomy plus 131I and thyroid stimulating hormone (TSH) suppression reduces disease recurrence and mortality, removes all intrathyroidal cancer, and facilitates the use of 131I scans and thyroglobulin measurements to monitor for recurrence. Recent decision analyses supporting this recommendation are summarized in this article. The recommendation comes with the caveat that total thyroidectomy must be performed safely with a low complication rate. With the institution of this appropriate treatment regimen, the prognosis for the majority of our patients with differentiated thyroid cancer is excellent.

Contemporary Childbirth Education Models

Since the 1960s, childbirth education advocates have attempted to persuade pregnant women that educational preparation for labor and birth is an essential component of the transition to motherhood. Initially, pregnant women who were seeking unmedicated births as a refuge from the inhumane childbirth treatments of the mid‐20th century embraced this view. However, with the changing childbirth climate, including a growing preference for medicated birth, scheduled inductions, and cesarean sections, attendance has diminished and childbirth education finds itself at a crossroads. Commonly used childbirth education models/organizations and several new emerging models along with the available research literature and recommendations for clinical practice and research are presented.     

Calcium and phosphorus contents of body parts of some domestic animals used as meat source in Nigeria

ObjectiveTo investigate the calcium and phosphorus contents of four domestic animals used as sources of meat in Nigeria.MethodsThe calcium contents of the body parts of the animals were determined using atomic absorption spectrometer. Their phosphorus contents were determined colorimetrically using the molybdenum blue method.ResultsThe calcium and phosphorus contents were significantly higher in the bone samples than in the other animal parts investigated (P<0.05). The calcium contents of all the edible parts were higher in chicken than in the other animals. High calcium and phosphorus contents were detected in the faeces of chicken and goat, and that of cattle and goat, respectively. Low calcium and phosphorus contents were detected in the urine samples. Calcium: phosphorus ratios calculated for the bones of chicken, cattle and goat were satisfactory.ConclusionsIn conclusion, calcium and phosphorus contents of the animal parts vary significantly and their relative contents may be related to the animal's diet. Chicken parts may be the preferred dietary source of these minerals. This study highlights the need for routine investigation of the mineral contents of food, which is necessary for proper nutritional guidelines.
