Vomiting and Diarrhea in Kids
Vomiting and Diarrhea in Kids samer kareem 4,978 Views • 2 years ago

Diarrhea in Children: Common Causes and Treatments Diarrhea is the body's way of ridding itself of germs, and most episodes last a few days to a week. Diarrhea often occurs with fever, nausea, vomiting, cramps, and dehydration. Some of the most common reasons kids get diarrhea include: Infection from viruses like rotavirus, bacteria like salmonella and, rarely, parasites like giardia. Viruses are the most common cause of a child's diarrhea. Along with loose or watery stools, symptoms of a viral gastroenteritis infection often include vomiting, stomachache, headache, and fever. When treating viral gastroenteritis -- which can last 5-14 days -- it's important to prevent fluid loss. Offer additional breast milk or an oral rehydration solution (ORS) to infants and young children. Water alone doesn't have enough sodium, potassium, and other nutrients to safely rehydrate very young children. Be sure to talk to your doctor about the amount of fluids your child needs, how to make sure he or she gets them, when to give them, and how to watch for dehydration. Older children with diarrhea can drink anything they like to stay hydrated, including ORS and brand-name products (their names usually end in "lyte"). Popsicles can also be a good way to get fluids into a child who's been vomiting and needs to rehydrate slowly.

Bone Tumor. Reasons
Bone Tumor. Reasons samer kareem 5,792 Views • 2 years ago

Bone tumors develop when cells in the bone divide without control, forming a mass of tissue. Most bone tumors are benign, which means they are not cancer and cannot spread. However, they may still weaken bone and lead to fractures or cause other problems. Bone cancer destroys normal bone tissue and may spread to other parts of the body (called metastasis). Benign Bone Tumors Benign tumors are more common than malignant tumors of the bones. These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. It is more common in people under age 20. Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s. Osteoblastoma is a single tumor that occurs in the spine and long bones, mostly in young adults. Enchondroma usually appears in bones of the hand and feet. It often has no symptoms. It is the most common type of hand tumor.

Cushing's Disease
Cushing's Disease samer kareem 5,953 Views • 2 years ago

Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.

Nelson syndrome refers to a spectrum of symptoms and signs arising from an adrenocorticotropin (ACTH)–secreting pituitary macroadenoma after a therapeutic bilateral adrenalectomy. The spectrum of clinical features observed relates to the local effects of the tumor on surrounding structures, the secondary loss of other pituitary hormones, and the effects of the high serum concentrations of ACTH on the skin. [1] The first case was reported by Nelson et al in 1958. [2]

Scoliosis
Scoliosis samer kareem 18,795 Views • 2 years ago

If you look at someone’s back, you’ll see that the spine runs straight down the middle. When a person has scoliosis, their backbone curves to the side. The angle of the curve may be small, large or somewhere in between. But anything that measures more than 10 degrees is considered scoliosis. Doctors may use the letters “C” and “S” to describe the curve of the backbone. You probably don’t look directly at too many spines, but what you might notice about someone with scoliosis is the way they stand. They may lean a little or have shoulders or hips that look uneven. What Causes Scoliosis? In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,327 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

How Does Laser Scar Removal Work?
How Does Laser Scar Removal Work? Scott 3,667 Views • 2 years ago

Scar revision includes techniques that improve the appearance of an unsightly scar, regardless of its size, type or age. This is typically not covered by insurance carriers and is treated as a cosmetic procedure. Though scars can never be completely removed, the appearance of scarring can be greatly diminished. Who Should Get Scar Revision? The best candidates for scar revision are in good health and have realistic expectations. Scar revision may be used to treat: Hyperpigmented scars Large or plainly visible scars Keloid scarring Raised scars Deep depression scars After scar revision, the appearance of your scar should be greatly reduced. Scar revision can improve the size, shape and color of your scar. Multiple procedures may be needed to achieve optimal results. There are several different techniques that can be used during your scar revision. During a consultation, we can discuss the best techniques and determine if you are a suitable candidate. What to Expect During Your Scar Revision Your scar revision may involve one or more of the following techniques: Topical treatments (gels, creams, external compression) can treat mild scarring or changes in pigmentation. Injectable treatments like dermal fillers are best for filling in scar depressions. These treatment options can provide long-lasting improvements, however, they are not always permanent. Surface treatments like chemical peels, dermabrasion, laser therapy and skin bleaching can improve skin tone and texture. More than one treatment may be needed to achieve optimal results. Surgical scar revision is only used in more severe cases. Reconstructive techniques like Z-plasty, tissue expansion, or skin grafting replace a prominent scar with a less noticeable scar. After Your Surgery Scar revision recovery varies depending on the procedure you have elected. Topical and injectable treatments rarely require downtime. Surface treatments and surgical removal can require several days of recovery. You may experience some temporary bruising, swelling, or discomfort. Over-the-counter or prescription medication can be used to manage pain. Topical and injectable treatments are likely to require sustained application to maintain results. The final results of surface treatments and surgical removal may not be visible for several weeks to months. It is important to protect the treatment area from direct sun exposure for several weeks. Additional details about your specific recovery will be discussed during your consultation.
