Background: Medical errors are those mistakes committed by healthcare professionals due to wrong execution of a planned healthcare action or execution of a wrong healthcare action plan whether or not it is harmful to the patient. Medical errors may cause patients to suffer and have huge financial costs for the healthcare system. Identifying and measuring medical errors and adverse events are essential for improving patient safety. The objectives of this research were to measure medical errors and adverse events rates, to identify their severity and also analyze their underlying causes in a general educational hospital in Tehran, Iran by using The Global Trigger Tool.
Methods: A descriptive, cross-sectional, and retrospective approach was used in this study. The medical records of 377 hospitalized patients between April 2015 and March 2016 were examined using simple random sampling method. Patient’s records were reviewed by a nurse using The Global Trigger Tool. Then, a physician authenticated the findings of the adverse events and rated their severity. The causes of adverse events were identified using brain storming and Ishikawa Cause And Effect Diagram.

Background: Time management is effective in controlling stress especially for medical residents. Time management in the surgical field and residential education is very important as they are directly involved in treating patients. Proper time management will help decrease work-related stress and increase efficacy, although there is no time management in medical courses. There are few studies in Iran in this field. So, we designed this study to assess the effects of time management on improvement of educational and therapeutic services in surgical residents of Imam Hospital.
Methods: This before–after study was done in Imam hospital between February-March 2015. In this before-after study, 18 surgical residents of Imam Hospital (residents of 1-4 years), were enrolled. Their activities were evaluated in 11 scopes. To evaluate the effects of this self-evaluation, 5 scopes were assessed by the staff. The time during two weeks spent on each item was claimed as a percentage of 336 hours in two weeks. The self-assessment results and their effects on their scores were considered. Data regarding age, sex, and marital status were also gathered. Data were analyzed using SPSS software.

Hyperthyroidism is one of the most important endocrine disorders, characterized by increased activity of the thyroid gland and excessive production of thyroid hormones. These hormones play a key role in regulating the body’s metabolism; therefore, their excess leads to a wide range of clinical manifestations. The most common symptoms include anxiety, restlessness, weight loss despite normal or even increased appetite, palpitations, excessive sweating, fine tremors of the hands, sleep disturbances, and heat intolerance. Some patients may also experience mood changes such as irritability and nervousness. On physical examination, rapid tendon reflexes, tachycardia, moist and thin skin, and in many cases the presence of goiter (thyroid enlargement) may be observed. The condition is more common in women than men and is most frequently seen between the ages of 20 and 50 years. Once hyperthyroidism is confirmed, the underlying cause of thyrotoxicosis must be determined. The most common cause is Graves’ disease, an autoimmune disorder that leads to diffuse thyroid enlargement and overproduction of hormones. Toxic multinodular goiter and solitary toxic adenoma are other important causes. For definitive diagnosis, blood tests measuring TSH, T3, and T4 are essential. In hyperthyroidism, TSH is typically suppressed while T3 and T4 are elevated. In addition to laboratory testing, thyroid ultrasound can help evaluate the structure of the gland, and a thyroid radioactive iodine uptake scan can further differentiate between different causes and determine disease activity. Several treatment options are available for managing hyperthyroidism. Antithyroid drugs such as methimazole or propylthiouracil inhibit the synthesis of thyroid hormones. Beta-blockers are often prescribed to control cardiovascular symptoms and reduce palpitations. Radioactive iodine therapy is a common and effective method that destroys the overactive thyroid tissue. In rare cases, or when other treatments fail, thyroidectomy (surgical removal of part or all of the thyroid gland) may be required. Overall, hyperthyroidism is a manageable condition, but it requires accurate diagnosis, careful selection of therapy, and close follow-up with a specialist. Patient cooperation and adherence to treatment play a crucial role in controlling symptoms and preventing long-term complications. This review will focus on describing the symptoms, causes, diagnostic methods, and treatment options.
