Treatment
Medically supervised sodium, chloride and potassium supplementation is necessary, and spironolactone can be also used to reduce potassium loss. Free and unqualified access to water is necessary to prevent dehydration, as patients maintain an appropriate thirst response. In severe cases where supplementation alone cannot maintain biochemical homeostasis, nonsteroidal anti-inflammatory drugs (NSAIDs) can be used to reduce glomerular filtration and can be very useful, although may cause gastric irritation and should be administered alongside stomach acid suppression therapies. Angiotensin-converting enzyme (ACE) inhibitors can also be used to reduce glomerular filtration rate. In young babies and children, a low threshold to check serum electrolytes during periods of illness compromising fluid intake is necessary.Surveillance renal ultrasound should be employed to monitor for the development of nephrocalcinosis, a common complication which further augments urinary concentrating difficulty. Prognosis
The limited prognostic information available suggests that early diagnosis and appropriate treatment of infants and young children with classic Bartter Syndrome may improve growth and perhaps intellectual development. On the other hand, sustained hypokalemia and hyperreninemia can cause progressive tubulointerstitial nephritis, resulting in end-stage kidney disease (kidney failure). With early treatment of the electrolyte imbalances, the prognosis for patients with classic Bartter Syndrome is good. History
The condition is named after Dr. Frederic Bartter, who, along with Dr. Pacita Pronove, first described it in 1960 and in more patients in 1962. References

Limb–girdle muscular dystrophy (LGMD) is a genetically heterogeneous group of rare muscular dystrophies that share a set of clinical characteristics. It is characterised by progressive muscle wasting which affects predominantly hip and shoulder muscles. LGMD usually has an autosomal pattern of inheritance. It currently has no known cure or treatment. Signs and symptoms
By definition, all limb girdle muscular dystrophies (LGMD) cause progressive proximal weakness, meaning weakness of the muscles on or close to the torso that worsens over time. Explicitly, LGMD preferentially affects muscles of the hip girdle, thigh, shoulder girdle, and/or upper arm. The muscle weakness is generally symmetric. Usually, the hip girdle is the first area to exhibit weakness, manifesting as difficulty walking, going up and/or down stairs, rising from a chair, bending at the waist, or squatting. Because of these difficulties, falling can occur frequently. Weakness of the shoulder girdle can make lifting objects, or even elevating the arms, difficult or impossible. Rate of progression varies between patients. Eventually, the abilities to run and walk can deteriorate. The disease commonly leads to dependence on a wheelchair within years of symptom onset, although some patients maintain mobility. Eventually the disease can affect other muscles such as the ones located in the face. By definition, LGMDs primarily affect skeletal muscles, although cardiac muscle can be affected to a lesser degree in select subtypes, which can cause palpitations
There can be significant variability in disease features and severity between LGMD subtypes, and even within any given LGMD subtype.
