概括
家族性低性高血症 (FHH) 是一种罕见的遗传性疾病,由于其与原发性甲状腺功能障碍症的重叠症状,因此存在诊断挑战. 基因检测对于准确的FHH诊断至关重要,特别是当与其他疾病如甲状腺癌同时发生时.
科学领域:
- 内分泌学 在内分泌学.
- 遗传学 是一个遗传学.
- 在瘤学瘤学.
背景情况:
- 家族性缺性高血症 (FHH) 是一种罕见的遗传性疾病,其特征是水平升高,甲状腺前激素 (PTH) 和缺性尿.
- FHH的临床表现通常模仿原发性副甲状腺症 (PHPT),使诊断复杂化,并可能导致不适当的手术干预.
- CASR基因突变是FHH最常见的原因,这强调了基因分析的重要性.
研究的目的:
- 报告一个具有挑战性的高血病病例,尽管最初怀疑PHPT,但诊断出FHH.
- 要突出在没有基因检测的情况下区分FHH和PHPT的诊断困难.
- 为了记录FHH与转移性微毛囊性甲状腺癌的罕见并发症.
主要方法:
- 临床病例介绍和生物化学分析.
- 尿液生物化学和成像研究用于高血症评估.
- 基因测序以确定CASR基因突变并确认FHH诊断.
主要成果:
- 最初的评估建议PHPT基于尿液生物化学和成像.
- 随后的诊断显示FHH-1和甲状腺外科手术后的转移性微粒状甲状腺癌.
- 一个与患者的父亲共享的新型错误的CASR突变被确定,证实了FHH诊断.
结论:
- 精确诊断高血性疾病需要遗传工具,特别是区分FHH和PHPT.
- FHH和甲状腺癌的同时发生非常罕见,以前只有一个报告.
- 这一案例强调了基因分析在管理疑似FHH的患者中的关键作用.

Skeleton and Calcium Homeostasis
5.7K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Synthesis and Functions of Calcitonin
4.0K
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

Urinary Tract Calculi I: Introduction
381
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
353
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

The Parathyroid Glands
4.2K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Hormones and Bone Tissue
3.6K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
