Although hypothyroidism may cause a wide range of muscle disturbances, an overt myopathy may rarely present as an isolated initial presentation of hypothyroidism. The frequency of myopathy in hypothyroidism ranges from 30 to 80%. The major muscular symptoms are weakness, muscular cramps and myalgia. Laboratorial investigation generally shows increased levels of muscle enzymes and low serum thyroid hormones, with high thyrotrophic-stimulating hormone (TSH) elevated. The electrophysiological study reveals myopathy, neuropathy or mixed pattern. The treatment consists in hormone replacement and the prognosis is good in most of the cases. We report two cases that developed cramps, myalgia, and weakness, one of them presented as a polymyositis-like syndrome. The muscle enzymes were increased with a raised level of TSH. The myopathy was the initial manifestation of hypothyroidism in these cases. Both the patient was treated by replacement of thyroxin with significant clinical and biochemical improvement.

The frequency of myopathy in hypothyroidism ranges from 30 to 80%. The major symptoms related are weakness, muscular cramps and myalgia. The pseudohyperthrophic form is called Hoffman's syndrome. The electrophysiological study reveals myopathy, neuropathy or mixed pattern. Laboratorial investigation generally shows increased levels of muscle enzymes and low serum thyroid hormones, with thyrotrophic-stimulating hormone (TSH) elevated. The treatment consists in hormone replacement and the prognosis is good in most of the cases. We report an adult male who developed muscular cramps, myalgia, weakness, pseudohyperthrophy, associated with facial edema and alteration of his voice. The muscle enzymes were increased and T4 was undetectable with a raised level of TSH. The myopathy was the initial manifestation of hypothyroidism in this case.

Abstract Background Parkinson’s disease (PD) is a neurodegenerative condition that has been reported following viral infections in rare occasions. Several neurological complications have emerged in association with coronavirus disease 2019 (COVID-19), since its declaration as a pandemic. Herein, we present a novel case of unexplained worsening of PD as the sole initial presentation of COVID-19, in the absence of fever or respiratory symptoms. Case presentation A 56-year-old male with advanced PD presented with severe rigidity, dystonic posturing of both feet, and confusion of 4 days duration. His condition progressed to an akinetic-rigid state and confusion during the following week, and a routine nasopharyngeal swab tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the 9th day of onset. He developed fever and dyspnea later and was intubated on the 10th day. Conclusion To our knowledge, worsening of PD symptoms as the sole initial manifestation of SARS-CoV-2 infection, in the absence of other cardinal features of COVID-19, has not been reported in the literature. We suggest testing for COVID-19 infection in patients with PD, especially advanced cases, who present with unexplained worsening of symptoms, even in the absence of COVID-19 cardinal features.

Abstract. In 21 hyperthyroid female patients studied on 29 occasions, high levels of red-cell 2,3-diphosphoglycerate (2,3-DPG) have been found (5.75 ± 0.7 mm) which, compared to a euthyroid control group (4.88 ± 0.4 mm), could not be accounted for by differences in haematocrit, haemoglobin or phosphataemia. A significant correlation was found (P < 0.05) between serum thyroid hormones and the 2,3-DPG concentration in the hyperthyroid patients. Eight of these patients were reexamined after treatment and normalization of thyroid function, showed a regression to normal 2,3-DPG values (4.81 ± 0.6 mm) which could not be attributed to variations in haematocrit, haemoglobin or phosphataemia either. We therefore deduce that the shift to the right in the haemoglobin oxygen dissociation curve observed in patients of this type may be due to an increase in the red-cell 2,3-DPG content.

Genomic Effects

Estradiol (E2) modulates a wide range of functions of the frontal cerebral cortex. From the onset of menopause, declining levels of E2 can cause cognitive disturbances and changes in behavior that can be counterbalanced by hormone replacement. To study the effect of E2 replacement on the cortical transcriptome in a rodent model with low serum E2 level, we treated middle-aged, ovariectomized rats with E2 or vehicle using osmotic minipumps for 4 wk. Six animals for each group were selected, and samples of their frontal cortex were subjected to expression profiling using oligonucleotide microarrays. The explored E2-regulated genes were related to neurotransmission (Adora2a, Cartpt, Drd1a, Drd2, Gjb2, Nts, and Tac1), immunity (C3, C4b, Cd74, Fcgr2b, Mpeg1, and RT1-Aw2), signal transduction (Igf2, Igfbp2, Igfbp6, Rgs9, and Sncg), transport (Abca1, Hba-a2, Slc13a3, and Slc22a8), extracellular matrix (Col1a2, Col3a1, Fmod, and Lum), and transcription (Irf7 and Nupr1). Seventy-four percent of the transcriptional changes identified by microarray were confirmed by quantitative real-time PCR. The genes identified by expression profiling indicated that chronic E2 replacement significantly altered the transcriptome of the frontal cortex. The genomic effects of E2 influenced dopaminergic and peptidergic neurotransmission, immune surveillance, adenosine and insulin-like growth factor signaling and transport processes, among other functions. Identification of these novel E2-regulated mechanisms highlights the wide range of genomic responses of the aging female frontal cerebral cortex subjected to hormone replacement. Some of the genomic effects identified in this study may underlie the beneficial effects of E2 on cognition, behavior, and neuroprotection.
