Hypophosphatemia is a condition wherein the blood phosphorus levels fall below 0.8 mmol/L. The normal blood phosphorus range is about 0.8 to 1.4 mmol/L in adults and slightly higher in children. Phosphorus plays an important role in energy formation and storage, nerve conduction, kidney function and formation of teeth and bones. Good dietary sources of phosphorus include meats, whole grain breads and cereals.
Typical symptoms of hypophosphatemia include bone pain, muscle weakness, confusion, seizures and anemia. Muscle cramps and Rhabdomyolysis are other symptoms. Certain medications like birth control pills, anabolic steroids and diuretics can cause hypophosphatemia. Hyperparathyroidism, Vitamin D deficiency and alcoholism can lead to this condition. When the levels of phosphorus fall too low, it can lead to easy bleeding and increased instances of infection. Kidney function test and Vitamin K blood test are conducted. Weak bones might be noticed on X-rays. Anemia and heart damage (Cardiomyopathy) is sometimes noticed.
Benign Prostatic Hyperplasia
Benign Prostatic Hyperplasia or BPH, also referred to as prostate gland enlargement is one of the most significant medical conditions among elderly men. It is a serious condition which proactively leads to other complications such as urinary tract infections and prostate gland functional abnormalities. The prostate gland is a two-lobed walnut shaped gland often associated with sperm mobilization. The growth of the prostate gland is directly related to age. The exact mechanism or the cause of this condition is not well determined. However, many studies indicate that the hormonal imbalance as the age increases in a man is responsible for the enlargement of the prostate gland. This refers to the excessive production of estrogen and decrease in the male sex hormone testosterone.
Clinical manifestations of BPH
The symptoms of Benign Prostatic Hyperplasia (BPH) worsen with age. The most common clinical symptom is repeated urination episodes. Often patients either complain of frequent urination, urinary urge or even difficulty in passing urine if there is an associated infection. These symptoms occur because of the inability of the tissues to make space for the enlarged or hypertrophic prostate gland. This lays pressure on the urethra to stimulate the process of urination frequently. Many patients complain of Nocturia. In addition to these symptoms, patients also suffer renal stones and reduced kidney function.
Diagnosis and Management of Benign Prostatic Hyperplasia
BPH is diagnosed based on various urological criteria. The American Urological Association recommends a score system. In most cases patients are examined to identify the presence of malignancy in the prostate region and hence test such as prostate specific antigen (PSA) is recommended along with cytological study of the prostate gland. Important parameters such as post-void residual volume, uroflowmetry, urinary pressure studies are conducted. Along with these diagnostic parameters, kidney function test is done to rule out other associated complications.
BPH can also transmit as a genetic disorder in some cases. The high risk groups are generally obese or suffer diabetes and hypertension. Along with these, other factors such as alcoholism, drug abuse and erectile dysfunction can lead to BPH.
Treatment of Benign Prostatic Hyperplasia
BPH patients are often kept under surveillance to avoid medical emergencies. The drugs administered for this condition reduce blood pressure and facilitate smooth muscle relaxation of the prostate gland thereby regulating urine flow. The drugs used are predominantly alpha blockers such as alfuzosin, terazosin and anticholinergics.
A kidney stone or renal calculus is a crystal concentration formed in the kidneys. Nephrolithiasis is formed from the minerals consumed in the diet and is largely composed of calcium. 75% of kidney stones are calcium stones. While Struvite stones are more commonly noticed in women, Uric acid stone can occur in men and women. Typically men are more affected by kidney stones than women. In most cases, the kidney stones are expelled by the body in the urine and no symptoms are noticed. But as the kidney stone grows in size, it can lead to pain and other symptoms. This is because of the obstruction to the ureters. A person suffering kidney stones feels pain in the area between the ribs and hip or lower abdomen and groin. Intermittent pain or renal colic is felt in spasms. It is sometimes accompanied by fever, blood and pus in the urine and pain on urination. There might be nausea and vomiting. There might be abnormal color of the urine.
Some foods that might increase the risk of kidney stone formation are refined sugars, sodium, vast quantities of animal protein and cola. Inadequate consumption of water adds to the risk factors. Those taking calcium supplements might also notice higher incidences of renal stone formation. This does not happen with high consumption of dietary calcium. Sodium, Uric acid and sulfurous amino acids also contribute to the formation of kidney stones. On the other hand, magnesium and potassium reduce urinary crystal formation by excreting citrate. Those with a family history of kidney stones are at higher risk of renal stones. Persons suffering kidney disorders, UTI and cystic kidney disease are also susceptible to kidney stones. Hyperoxaluria is a condition where the body produces too much oxalate. When this quantity is too large to be dissolved in urine, it leads to the formation of renal stones.
Ultrasound is done to confirm the presence of kidney stones. X-rays and IVP (intravenous pyelogram) aid in imaging the renal stone. Kidney function test and blood tests are also done. The size of kidney stones can range from a small grain of sand to a pearl. It can be smooth or jagged. Over time, renal stones can cause irreversible kidney damage. Most small stones in the kidney do not need treatment or removal. But if the kidney stones cause urine blockage, bleeding, infection or keep growing in size, they need to be removed. Some kidney stones, especially those consisting of uric acid or cystine can be treated with medicines. Else endoscopic removal of kidney stones with a uterescope is done. Lithotripsy is often used to break the stone into smaller pieces so that they can be flushed with the urine.
