Agranulocytosis is a rare and critical adverse effect of antithyroid drugs (ATD). The occurrence of agranulocytosis in continuous ATD treatment patients is well known; however, a case of ATD agranulocytosis occurring following the discontinuation of methimazole (MMI) treatment is not a usual situation. We herein describe a case of a 41-year-old woman who was previously administered methimazole (MMI) for ten days and developed ATD-induced agranulocytosis and symptoms of an upper respiratory tract infection after three weeks following discontinuation of MMI treatment. A thorough hematologic and serological evaluation did not disclose an alternative cause for the agranulocytosis. After receiving empirical antibiotic treatment, she responded successfully with clinical improvement of her symptoms and resolved neutropenia on the seventh day. This case is atypical because agranulocytosis developed after discontinuation of MMI, which strengthens the importance of remaining alert for signs of agranulocytosis even after discontinuation of ATD treatment.

Migratory Polyarthritis

Antithyroid drugs (ATD’s) are widely used as the first line treatment option for the management of hyperthyroidism, especially for patients with Graves’ disease. They are classified into thionamide (Methimazole, Carbimazole and Propylthiouracil) and Non-thionamide (Iodine containing compounds) ATD’s. These drugs are associated with various types of adverse effects ranging from mild to potentially life threatening. Antithyroid arthritis syndome (AAS) is one of the major and uncommon side effects of ATD therapy requiring immediate drug discontinuation and hospitalization presents itself with myalgia, arthralgia and arthritis along with fever and rash of varying severity and non-specific laboratory findings, making its diagnosis and management clinically challenging. Here we report the case of 32 year old female with Graves’ disease who experienced severe migratory polyarthritis after the initiation of methimazole therapy. Her symptoms started to disappear after the prompt withdrawal of methimazole. We also concluded that this adverse effect of ATD’s might not be dose dependent by comparing our case with 6 other case reports of AAS. Here our objective is to raise awareness among the clinicians regarding the differential diagnosis and management of this major, uncommon and potentially life threatening adverse effect of ATD therapy.

Graves' disease is an autoimmune disease and is the main cause of hyperthyroidism. This study aims to characterize the evolution of treatment with antithyroid drugs in patients with Graves' disease in a tertiary care referral center. We observed that the use of propylthiouracil was a predictor factor of a greater chance of having some adverse effect in relation to the use of methimazole. Regarding the evolution of treatment, high concentrations of TRAb were the main determinant for non-remission of the disease with the use of thionamides.

In the electron microscopy of biological sections the adverse effect of chromatic aberration on image resolution is well known. In this paper calculations are presented for the inelastic and elastic image intensities using a wave-optical formulation. Quantitative estimates of the deterioration in image resolution as a result of chromatic aberration are presented as an alternative to geometric calculations. The predominance of inelastic scattering in the unstained biological and polymeric materials is shown by the inelastic to elastic ratio, I/E, within an objective aperture of 0.005 rad for amorphous carbon of a thickness, t=50nm, typical of biological sections; E=200keV, I/E=16.

SummaryThyroid hormones are essential development factors and maternal thyroid dysfunction may cause pregnancy complications and diseases in the fetus/child. In the present review we discuss new data on the incidence of Graves'-Basedow disease (GBD) in and around pregnancy, and how hyperthyroidism may affect the risk of spontaneous abortion and stillbirth.A special concern in pregnant women is the potential side effects from the use of antithyroid drugs (ATDs). One type of side effects is the allergic/toxic reactions to the drugs, which seem to be similar in and outside pregnancy, and another is that ATDs tend to over treat the fetus when the mother with GBD is made euthyroid. To avoid fetal hypothyroidism, the lowest possible ATD dose should be used to keep maternal thyroid function at the upper limit of normality with low serum TSH. Birth defects after the use of methimazole (MMI) (or its prodrug carbimazole) have been considered to be very rare, and no risk has previously been associated with the use of propylthiouracil (PTU). However, a recent Danish national study found that 1/30 of children exposed to MMI in early pregnancy had birth defects associated with this, and many defects were severe. PTU exposure was associated with defects in 1/40, and these defects were less severe. Proposals are given on how to reduce the risk of ATD associated birth defects.
