Tamsulosin is used to treat Benign Prostatic Hyperplasia (BPH), prescribed annually to about 12.6 million patients worldwide. It is an alpha-adrenergic antagonist that reduces the tone of the prostate smooth muscle involved in the pathophysiology of BPH. By acting on alpha 1A receptors, predominant in the prostate, tamsulosin also acts on receptors present in the brain. This study consisted of a literature review aimed at disseminating scientific knowledge about the relationship between the use of tamsulosin and the onset of dementia. Pubmed, Scopus, Scielo, Embase, and Web of Science studies involving dementia in patients using tamsulosin in the last five years were selected. The review showed a risk correlation and a higher incidence of dementia in treated patients. The risk ratio, when compared to other medicines, approached 1.20. In conclusion, it was identified the need for clinical trials with higher sampling power to increase relational significance due to the high prevalence of BPH and the extensive use of tamsulosin in elderly patients with the disease.
坦索罗辛用于治疗良性前列腺增生症(BPH),每年为全球约1260万患者开具处方。它是一种α-肾上腺素能拮抗剂,可降低前列腺增生病理生理学中涉及的前列腺平滑肌张力。坦洛新通过作用于前列腺中占主导地位的α1A受体,也作用于大脑中的受体。这项研究包括一篇文献综述,旨在传播关于坦索罗辛的使用与痴呆症发作之间关系的科学知识。选择了过去五年中使用坦索罗辛的痴呆患者的Pubmed、Scopus、Scielo、Embase和Web of Science研究。该综述显示,在接受治疗的患者中,痴呆症的风险相关性较高。与其他药物相比,风险比接近1.20。总之,由于前列腺增生的高患病率和坦索罗辛在老年患者中的广泛使用,确定了需要具有更高抽样能力的临床试验来增加相关性意义。

Prolactinomas constitutes a major bulk of pituitary adenomas. All symptomatic prolactinomas require dopamine agonist (DA) therapy. Impulse control disorders (ICD) or pathological behaviours are rare adverse events described with use of DA. Herein we are describing a male patient with pathological gambling and doctor shopping following use of bromocriptine and higher dose of cabergoline.The pathological behaviour disappeard after debulking surgery, reduction in cabergoline dose and several sessions of counselling. Physicians prescribing DA should be aware of this potential adverse event.This should be emphasized to the patient and family members before starting DA and physician should be inquisitive for eliciting pathological behaviour on follow up.

MicroRNAs (miRNAs) are short single-stranded noncoding RNAs (20- to 25-nucleotide (nt) long) representing a class of small regulatory RNAs. By inhibiting the translation of target mRNAs, miRNAs regulate gene expression posttranscriptionally and thus play an important role in a wide range of cellular processes. Currently, there are two known types of miRNAs: intergenic and intronic miRNAs. Biogenesis of an intergenic miRNA starts with the synthesis of a primary miRNA transcript (pri-miRNA) catalyzed by types-II or -III RNA polymerase (Pol-II/III). Pri-miRNAs are processed in the nucleus by the ribonuclease Drosha into a miRNA precursor (pre-miRNA) approximately 60-nt in length. After being transported into the cytoplasm, these pre-miRNAs are further processed into mature and functional miRNAs by the cytoplasmic ribonuclease Dicer. Mature miRNAs then associate with a number of proteins to form the RNA-induced silencing complex (RISC) that bind with target mRNAs having total or partial complementary sequences to the miRNAs and initiate the inhibition of subsequent protein translation via RNA interference (RNAi).

Non-functioning pituitary adenomas (NFPA) are 30% of all pituitary adenomas. Although benign in nature but they may be invasive and recurrent. Markers of recurrence are needed to guide patient management. Recteptor Tyrosine Kinases (RTK) may sereve as therapeutic marker for recurrence as they can targeted by already available tyrosine kinase inhibitors. To examine differential RTK phosphorylation pattern of recurrent NFPAs, we recruited 20 patients and grouped them as non-recurrent (n=10), and recurrent (n=10). Recurrence was determined by follow-up of 15 years. We then performed a membrane-based antibody array (ARY001B) for the determination of the relative phosphorylation of 49 tyrosine kinases in recurrent NFPAs. As the experiment was replicated on two set of membranes, each tyrosine kinase was represented in quadruples. Student’s t-test was performed to compare the means between two groups. We found ErbB2, PDGFR beta, SCFR, Trk, VEGFR1, VEGFR2, EphA3, and Alk significantly hyperphosphorylated in recurrent NFPAs. Out of these eight hyperphosphorylated tyrosine kinases ErbB2 and EphA3 were 1.6 (p=0.01) and 1.9 (p=0.002) times hyperphosphorylated in recurrent NFPAs. This result indicates that EphA3 may be an effective therapeutic target in recurrent NFPAs.

Cushing syndrome is a state of prolonged exposure to excess cortisol production. Causes can be varied ranging from exogenous intake or endogenous production from a pituitary source due to overproduction of adrenocorticotropic hormone (ACTH) or due to over secretion from unilateral or bilateral adrenal glands. Cushing syndrome in an adult can present with proximal muscle weakness, facial plethora, wasting of the extremities with increased fat in the abdomen and face, wide purplish striae, bruising with no obvious trauma, and supraclavicular fat pads. Here, we report a 38 year old male who presented with suspicion of having Cushing syndrome due to his clinical manifestations and high cortisol levels. He presented to the clinic with new onset diabetes, severe hypertension, chronic abdominal pain and distension which was being investigating by different specialties. The patient underwent CT scan of the abdomen which show right adrenal adenoma and on examination, he was found to have proximal weakness and purple striae. Laboratory data showed high morning cortisol, 24 urine free cortisol and ACTH levels which were strongly suggestive of ACTH independent Cushing syndrome.

Thyroid hormones affect all organ systems and, in excess, can cause increased metabolic rate, heart rate, ventricle contractility, and gastrointestinal motility as well as muscle and central nervous system excitability. Thyroid storm is the extreme manifestation of thyrotoxicosis with an estimated incidence of 0.20 per 100,000 per year among hospitalized patients in Japan. The mortality of thyroid storm without treatment ranges from 80% to 100%; but with treatment, the mortality rate is between 10% and 50%. The diagnostic strategy for thyroid storm may take into consideration Burch–Wartofsky scoring or Akamizu's diagnostic criteria. Multiple treatment aims need to be addressed in managing thyroid storm effectively. This paper puts together all aspects to be considered for the management of hyperthyroidism and thyroid storm during the acute and emergency phase as well as consideration of special populations.

Pioglitazone (brand name Actos) is a prescription drug of the thiazolidinedione (TZD) class with hypoglycemic (antihyperglycemic, antidiabetic) action to treat diabetes. Pioglitazone is one of the antidiuretic agents used in the management of type 2 diabetes mellitus (DM). The effect of pioglitazone on blood glucose, lipid profile, liver enzymes and weight has been shown with conflicting results. In this study we aim to evaluate the effect of pioglitazone on the weight, lipid profile and liver enzymes in patients with DM. Pioglitazone is used to lower blood glucose levels in the treatment of diabetes mellitus type 2 (T2DM) either alone or in combination with a sulfonylurea, metformin, or insulin.

Diabetic retinopathy (DR) is a leading cause of vision-loss globally. Of an estimated 285 million people with diabetes mellitus worldwide, approximately one third have signs of DR and of these, a further one third of DR is vision-threatening DR, including diabetic macular edema (DME). The identification of established modifiable risk factors for DR such as hyperglycemia and hypertension has provided the basis for risk factor control in preventing onset and progression of DR. Additional research investigating novel risk factors has improved our understanding of multiple biological pathways involved in the pathogenesis of DR and DME, especially those involved in inflammation and oxidative stress. Variations in DR prevalence between populations have also sparked interest in genetic studies to identify loci associated with disease susceptibility.

Reproductive Endocrinology is a medical specialty for infertility, menopause, and other issues with reproductive hormones. Reproductive endocrinologists are OB/GYN (obstetrics and gynecology) doctors with special training to help both men and women with problems related to reproductive hormones. Sometimes, this specialty is called reproductive endocrinology and infertility because much of their work focuses on helping women to become pregnant and carry a baby to term.
