Hyperkalemia is a condition that occurs when compromised kidney function leads to excessive levels of potassium in the bloodstream. This buildup triggers a mineral imbalance in the body that can degrade the function of the heart. Acute hyperkalemia is a critical manifestation of this disorder, and left untreated it may result in cardiac arrest and death. Treatment for acute hyperkalemia includes steps to protect the body and lower potassium levels. Thrombus is the term used to describe a blood clot that forms in the heart or a blood vessel. When a thrombus forms in the deep veins of the body, it can trigger a condition called deep vein thrombosis (DVT). Due to over-pronation the foot continues to roll inwards when it really should be pushing off and outwards, because of which the lower leg also follows the internal rotation instead of the external rotation, thereby placing a lot of strain on the leg muscles (especially the calf muscles) causing leg ache and shin splits. The knee-cap, a hinge joint designed to flex and extend like a door and not rotate, gets displaced due to the twisting of the leg. Similarly, when the legs rotate inwards, the pelvis is forced to tilt forward, thereby constantly straining the lower back muscles. Some of the friendliest people I know have a special condition called Trisomy 21 or Down syndrome. In these individuals many skin, bony, muscle and joint conditions exist due to abnormal collagen development. One of the types of collagen (Type VI) is encoded by a gene on chromosome 21. The resulting effect is increased joint laxity or looseness of the ligaments that attach bone to bone or tendons that attach muscles to bone (hypotonia of muscles). The ligamentous laxity and hypotonia will then lead to multiple conditions encountered in the feet of a Down syndrome individual. Ultrasound shows a hypoechoic nodule between the metatarsal interspace. Ultrasound had a 65% specificity and a 98% sensitivity for Morton neuromas. Ultrasound is not good at assessing the size of the lesion (1)C. MRI is used to ensure that compression is not caused by a malignant tumor in the foot. MRI is helpful in determining how much of the nerve to resect surgically. MRI has a sensitivity of 83% and a specificity of 99% (1)C. Corticosteroid injection can significantly reduce symptoms. Inject 1–2 mL lidocaine and 0.5–1 mL dexamethasone just proximal to the metatarsal heads. More than 1 injection is often needed, usually once a week × 3 weeks (2). Where to start? If you are asymptomatic, don't worry so much. There is nothing you can do short of surgery that will recreate an arch. When you have a flatfoot, it is often a combination of soft tissue failure and boney alignment dysfunction. The biomechanics of your foot becomes compromised. You can still walk but for some, it is not without discomfort. Simple measures such as orthotics and bracing are often all that is needed to rid the discomfort. This also means that shoes play an important role. Every day of the summer I have patients strolling into my office in flip flops and other poor excuses for shoes.
