Swimming as a recreational activity is excellent for individuals with CP order prandin 1mg on line diabetes test london. For many children who have a high-energy demand of walking in middle childhood 1mg prandin mastercard diabetes 504 plans, learning to swim and using this as the physical conditioning ex- ercise is an excellent option. A major problem for individuals whose main motor ability is by wheelchair is finding an exercise technique that can be performed comfortably but still provide cardiovascular stress. Swimming is a primary option for many of these individuals. If a childhood swimming program teaches children to be comfortable in water and learn to swim, there will potentially be lifelong benefits. There are some children with diplegia who can learn to become competitive swimmers and even compete with nor- mal age-matched peers. Therapy, Education, and Other Treatment Modalities 175 Martial Arts The martial arts are an excellent choice for some children, even those who require assistive devices for walking. The routines in martial arts are usually individualized for the speed at which a child can learn; many of the routines also stress balance reaction, stretching, and large joint range of motion. Also, there is a clear system for making progressive steps with awarding levels of achievement, which is a great motivator for many children. The training for the martial arts occurs in community locations with regular community peers, which is another major advantage. The main problem with the mar- tial arts is the difficulty in finding instructors who are interested in teaching individuals with disabilities. Another problem of the martial arts for individ- uals who become very enthused about the sport is that at the higher levels of skill the motor impairments also make advancement very difficult. Sports Encouraging children with CP to get involved with typical age-matched sport activities is an excellent alternative to medically based therapy programs, especially for children with motor skills that allow them to enjoy the activ- ity. Physical therapists are in an excellent position to recommend to families specific sporting activities that would likely work for their children. For am- bulatory young children, the beginner soccer programs work well. For chil- dren with a need to work on balance and motor control, dance programs are an excellent option. Acupuncture Acupuncture with functional training has been reported to increase both children’s motor function and cognitive function. Apparently, the acupuncture meridians are closely related to the Vojta massage points, and there is a suggestion that both techniques may be stimulating the same sys- tem. The use of pressure point manipulation by acupressure causes no harm if it is not uncomfortable to the children; however, there is no clear objective benefit of acupressure. Massage and Myofascial Release Therapy A major aspect of the Vojta technique of therapy is stimulation through a se- ries of massage points. There has been increased use of massage by some therapists, including borrowing techniques from chiropractors. Myofascial release therapy is one such technique that has been developed emanating from chiropractor practice. Although myofascial release therapy is not usu- ally described as massage, it is in fact a massage program with a minimal joint range of motion component. There are no English-language reports on the specific efficacy of massage compared with no therapy or other therapy modalities. Benefit has been reported for massage, reflexology, and other manipulations that are widely used in Eastern Europe and Russia. If the therapy is in any way uncomfortable for these children, it cannot be jus- tified based on currently available data. Hyperbaric Oxygen Therapy There has been increased interest in the use of hyperbaric oxygen therapy for children with CP under the theory that more oxygen will make the brain function better. A small study suggested a possible benefit55; however, there have also been complications reported from this therapy. This as yet unreported study has apparently shown that there is a small benefit to the child by sitting with the parent in the hyperbaric oxygen chamber for approximately 10 hours each week. However, the addition of hyperbaric oxygen to the chamber adds no additional benefit. Based on these results, there is no role for hyperbaric oxygen therapy in children with CP. Space Suit Therapy Therapy with children in space suits, initially designed to counteract the weightlessness of space by being pressurized and add elastic resistance to movement, was first investigated in Russia in the early 1990s.

Intravenous fluids were started, he was not allowed to take anything by mouth, a nasogastric tube was passed and placed on constant suction, and symptomatic therapy was started for pain and nausea. When his condition had stabilized, Michael was sent for an ultrasonographic (ultrasound) study of his upper abdomen. Al Martini has continued to abuse alcohol and to eat poorly. After a par- ticularly heavy intake of vodka, a steady severe pain began in his upper mid-abdomen. This pain spread to the left upper quadrant and eventually radiated to his mid-back. He began vomiting nonbloody material and was brought to the hospital emergency room with fever, a rapid heart beat, and a mild reduction in blood pressure. On physical examination, he was dehydrated and tender to pres- sure over the upper abdomen. His vomitus and stool were both negative for occult blood. Blood samples were sent to the laboratory for a variety of hematologic and chemical tests, including a measurement of serum amylase and lipase, digestive enzymes normally secreted from the exocrine pancreas through the pancreatic ducts into the lumen of the small intestine.

Further studies confirmed the presence of decreased mineralization (decreased calcification) of the skeleton (called osteopenia if mild and osteoporosis if more severe) and high methionine and homocysteine but low cystine levels in the blood buy prandin 0.5 mg on line diabetes rice. All of this information order prandin 0.5mg on-line diabetes test after 2 hours, plus the increased length of the long bones of Homer’s extremities and a slight curvature of his spine (scoliosis), caused his physician to suspect that Homer might have an inborn error of metabolism. THE ROLE OF COFACTORS IN AMINO ACID METABOLISM Amino acid metabolism requires the participation of three important cofactors. Pyridoxal phosphate is the quintessential coenzyme of amino acid metabolism (see Chapter 38). All amino acid reactions requiring pyridoxal phosphate occur with the amino group of the amino acid covalently bound to the aldehyde carbon of the coen- zyme (Fig. The pyridoxal phosphate then pulls electrons away from the bonds around the -carbon. The result is transamination, deamination, decarboxylation, -elimination, racemization, and -elimination, depending on which enzyme and amino acid are involved. The coenzyme FH4 is required in certain amino acid pathways to either accept or donate a one-carbon group. Chapter 40 describes the reactions of FH4 in much more detail. Pyridoxal phosphate covalently attached to an amino acid substrate. The arrows indicate which bonds are broken for the various types of reactions in which pyridoxal phos- phate is involved. The X and Y represent leaving groups that may be present on the amino acid (such as the hydroxyl group on serine or threonine). The coenzyme BH4 is required for ring hydroxylations. The reactions involve molecular oxygen, and one atom of oxygen is incorporated into the product. BH4 is important for the synthesis of tyrosine and neurotransmitters (see Chapter 48). AMINO ACIDS DERIVED FROM INTERMEDIATES OF GLYCOLYSIS Four amino acids are synthesized from intermediates of glycolysis: serine, glycine, cysteine, and alanine. Serine, which produces glycine and cysteine, is synthesized from 3-phosphoglycerate, and alanine is formed by transamination of pyruvate, the product of glycolysis (Fig. When these amino acids are degraded, their car- bon atoms are converted to pyruvate or to intermediates of the glycolytic/gluco- neogenic pathway and, therefore, can produce glucose or be oxidized to CO2. Serine In the biosynthesis of serine from glucose, 3-phosphoglycerate is first oxidized to a 2-keto compound (3-phosphohydroxypyruvate), which is then transaminated to form phosphoserine (Fig. Phosphoserine phosphatase removes the phosphate, forming serine. The major sites of serine synthesis are the liver and kidney. Serine can be used by many tissues and is generally degraded by transamination to hydroxypyruvate followed by reduction and phosphorylation to form 2-phospho- glycerate, an intermediate of gycolysis that forms PEP and, subsequently, pyruvate. Glucose Glycine Serine also can undergo -elimination of its hydroxyl group, catalyzed by serine dehydratase, to form pyruvate. Regulatory mechanisms maintain serine levels in the body. When serine levels fall, 3-Phosphoglycerate Serine serine synthesis is increased by induction of 3-phosphoglycerate dehydrogenase and by release of the feedback inhibition of phosphoserine phosphatase (caused by higher lev- els of serine). When serine levels rise, synthesis of serine decreases because synthesis 2-Phosphoglycerate Cysteine of the dehydrogenase is repressed and the phosphatase is inhibited (see Fig. Glycine Pyruvate SO4 Glycine can be synthesized from serine and, to a minor extent, threonine. The major route from serine is by a reversible reaction that involves FH4 and pyridoxal phos- Alanine phate (Fig. Tetrahydrofolate is a coenzyme that transfers one-carbon groups Fig. Amino acids derived from interme- at different levels of oxidation.
