The authors examined the British medical literature published in the 45-year-period following Parkinson's treatise on the shaking palsy to determine the number and type of references to the shaking palsy or paralysis agitans during this particular period. Several sources suggest that Parkinson's 1817 treatise on the shaking palsy received little immediate attention in his native country, England, and that not until 1861, in France, did Charcot began to elucidate the clinical features of this entity, separating it from other neurologic disorders (for example, multiple sclerosis). A review of the British medical literature from the 45-year-period 1817-1861 revealed a number of references to paralysis agitans, including those by Cooke (1820), Good (1824 and 1829), Elliotson (1827, 1829, 1830, 1831, and 1833), Gowry (1831), anonymous (1832), Todd (1833), Watson (1836), Gibson (1839), Hall (1838 and 1841), Thompson (1842), Graves (1843), Birkett (1853), Paget (1855), and Reynolds (1855). Many of these did not report new or personally observed cases, did not separate Parkinson's disease from other disease entities characterized by both "shaking" and "palsy" (for example, tonic-clonic seizures), or misattributed motor signs to dysfunction of the pyramidal system rather than an extrapyramidal system (that is, attributing bradykinesia or rigidity to weakness). Although there were several references to "shaking palsy" in the early- to mid-19th-century British medical literature, there were few original case reports of Parkinson's disease. This may have contributed to the fact that during this period little was added to the original observations made by Parkinson in 1817. In particular, the separation of bradykinesia and weakness did not become apparent until later work by the French.

Most familial cases of autosomal dominant low frequency sensorineural hearing loss (LFSNHL) are attributable to mutations in the wolframin syndrome 1 (WFS1) gene at the DFNA6/14/38 locus. WFS1 mutations at this locus were first described in 2001 in six families segregating LFSNHL that was non-progressive below 2,000 Hz; the causative mutations all clustered in the C-terminal domain of the wolframin protein. Mutations in WFS1 also cause Wolfram syndrome (WS), an autosomal recessive neurodegenerative disorder defined by diabetes mellitus, optic atrophy and often deafness, while numerous single nucleotide polymorphisms (SNPs) in WFS1 have been associated with increased risk for diabetes mellitus, psychiatric illnesses and Parkinson disease. This study was conducted in an American family segregating autosomal dominant LFSNHL. Two hearing impaired family members also had autoimmune diseases-Graves disease (GD) and Crohn disease (CD). Based on the low frequency audioprofile, mutation screening of WFS1 was completed and a novel missense mutation (c.2576G --> A) that results in an arginine-to-glutamine substitution (p.R859Q) was identified in the C-terminal domain of the wolframin protein where most LFSNHL-causing mutations cluster. The family member with GD also carried polymorphisms in WFS1 that have been associated with other autoimmune diseases.

Eccrine hidrocystoma is a benign tumor derived from eccrine sudoriparous glands. Most eccrine hidrocystomas are solitary and asymptomatic lesions. Multiple hidrocystomas are unusual and have been associated with Graves' disease, Parkinson's disease, and idiopathic craniofacial hyperhidrosis. This report describes the successful treatment of multiple center facial eccrine hidrocystomas associated with craniofacial hyperhidrosis with 0.5% glycopyrrolate aqueous solution applied locally for 1 week. The present authors obtained a very significant improvement without leaving any trace of clinical examination. Multiple eccrine hidrocystomas are a rare condition and, to date, no effective treatment has been reported. Topical glycopyrrolate is a very good first-line treatment option.

To maintain a physical organization and a different composition of its surroundings environment, living beings use a great part of the energy that they produce. Vital processes require an elevated number of reactions which are regulated and integrated by chemical messengers. They use autocrine, paracrine, endocrine and synaptic signals through receptors of cell surface, nuclear or associated with ionic chanels, enzymes, trimeric G proteins and to intracellular kinases. Through these mechanisms pheromones play an important role in the relationships between different individuals, and hormones are able to regulate the integrative functions of our organism. In the nervous system, neurotransmitters, neuromodulators, sensors and receptors between other messengers, play functions of great relevance, while growth factors stimulate cell proliferation and cytokines have many effects but the most important is the ones related with the control of the immflamatory process. Alterations of these messengers permit us a better understanding of the diseases and possibly of its treatments in a near future. Modifications of the expression of genes from the nuclear and mitochondrial genomas are responsible of monogenic, polygenic and mitochondrial diseases, while alterations in the activities of dopamine and serotonin neurotransmitters are related with schizophrenia, Parkinson disease and depression, respectively. Other example is the hyperthyroidism of the Graves-Bassedow disease due to the competitive interference of the LATS immunoglobulin with TSH at the level of the folicular cells producing thyroid hormones Twenty five years ago in the reviews on the mechanisms of insulin action, there was presentations in which the insulin receptor was located in the plasma membrane of the target cells while in the cytoplasm only a big interrogative was observed, that at present is replaced by chemical mediators cascades responsible of the multiple effects of insulin. This finding is similar to many other processes, and all together constitute a new approach for a better knowledge of the biological processes and as a consequence of the diseases.

We present three patients with histories of the typical unsteady feeling in the legs while standing still which disappears when walking or sitting down. An orthostatic tremor is a disorder that is difficult to recognise because patients describe balance disturbances rather than tremors. Clinical findings include a fine tremor in the legs which may be invisible but can be heard on auscultation and felt on palpation of the leg muscles. The diagnosis is confirmed by EMG which reveals a pathognomonic tremor of 13-18 Hz while the patient is standing upright. Its pathophysiology is unknown but a disorder related to proprioceptive feedback has been suggested. The tremor can be associated with Parkinson's disease, Graves' disease, and cerebellar or pontine lesions which should be excluded by laboratory investigations and MRI. There is little evidence available on effective treatments, but clonazepam seems to be the first drug of choice, followed by gabapentin. Levodopa can be tried in patients with parkinsonism.

A 55-year-old Filipina with Grave's disease, diabetes, hypertension, bronchial asthma, Parkinson's disease and a history of adverse drug reaction to penicillin consulted due to high-grade fever and sore throat. Patient was diagnosed with aplastic anaemia secondary to methimazole and was treated with high-dose granulocyte colony stimulating factor, thrombopoietin and mesterolone. Antibiotics used included levofloxacin, clindamycin, amikacin and fluconazole. Due to bleeding and slow recovery of blood parameters, 30 units of platelets and 7 units of packed red blood cells were transfused during her 22-day admission. This case presents a life-threatening adverse drug reaction in a patient with co-morbid conditions that complicate recovery and limit one's therapeutic options.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons. Dopaminergic system is interconnected with the hypothalamic-pituitary-thyroid axis. Dopamine (DA) upregulates thyrotropin releasing hormone (TRH) while downregulating thyroid stimulating hormone (TSH) and thyroid hormones. Moreover, TRH stimulates DA release. PD is associated with impaired regulation of TSH and thyroid hormones (TH) levels, which in turn associate with severity and different subtypes of PD, while levodopa and bromocriptine treatment can interfere with hypothalamic-pituitary-thyroid axis. Thyroid disturbances, including hypothyroidism, Hashimoto's thyroiditis (HT), hyperthyroidism and Graves' disease (GD) not only increase the risk of PD but also share some clinical signs with PD. Also, several genes including RASD2, WSB1, MAPT, GIRK2, LRRK2 and gene products like neurotensin and NOX/DUOX affect the risk for both PD and thyroid disease. Hypothyroidism is associated with obesity, hypercholesterolemia, anemia and altered cerebral blood flow which are associated with PD pathology. Herein we provide a comprehensive view on the association between PD and thyroid hormones regulation and dysregulations, hoping to provide new avenues towards targeted treatment of PD. We performed a comprehensive search in literature using Pubmed and Scopus, yielding to a total number of 36 original articles that had addressed the association between thyroid hormone disorders and PD.
