American Academy of Pediatrics: Pediatric Nutrition Handbook, ed 6, Elk Grove Village, 2009, pp 39­40. What advice should be given to a mother who plans to express and save breast milk for later feedings? Ideally, she should collect the milk as cleanly as possible and then store it rapidly at 3 to 4 C or colder; the milk should then be used within 5 days. Alternatively, breast milk can be stored in the freezer compartment of a refrigerator for about 6 months. If more prolonged storage is necessary (12 months), the milk should be kept frozen at a temperature of А20 C or lower (usually in a separate freezer). Numerous studies show that the amount of methadone transferred through milk is low across the range of doses typically used and not likely to result in toxicity to the infant. The term 60/40 refers to the percentage of whey (lactalbumin) and casein in human milk or cow milk formulas. The 60/40 ratio is of particular advantage to the preterm infant because it is associated with lower levels of serum ammonia and a decreased incidence of metabolic acidosis. Only human milk or formulas that supply protein in this ratio provide adequate amounts of the amino acids cystine and taurine, which may be essential for the preterm infant. Generally, low-iron formula has 4 to 6 mg/L of elemental iron, whereas regular iron-fortified formula has 12 mg/L. Although a greater percentage of iron is absorbed from the ingested low-iron formula, the quantity may not be sufficient to protect against the development of iron-deficiency anemia. In addition, despite anecdotal experiences, the incidence of colic, constipation, vomiting, and fussiness does not vary among infants fed the two formulas. The American Academy of Pediatrics recommends that all formula fed to infants be iron fortified. As a result of the growing concerns about the relationship of sunlight exposure and skin cancer, the low concentration of vitamin D in breast milk, and the inability to predict adequate exposure as a result of diverse lifestyle and cultural practices, cases of rickets in breastfed infants have been reported. If alimentation is being administered through a peripheral vein, is heparinization necessary? Therefore, heparin should be used whenever fats are being administered intravenously. Nonnutritive sucking is a mode of sucking that is unique to humans and that is characterized by a highly regular, burst-pause pattern. Nonnutritive sucking occurs in all sleep and awake states, although it is seen less often during quiet sleep and crying. How do protein requirements vary with the mode of nutrient delivery (intravenous versus enteral)? Whether delivered intravenously or enterally, the protein requirements needed to achieve in utero accretion rates are similar. Humans cannot synthesize fatty acids with double bonds in the o-6 and o-3 positions. Therefore, linoleic acid (o-6) and linolenic acid (o-3) must be provided in the diet to serve as precursors for fatty acids with these bonds. In infants weighing less than 1750 g who experience delay in or difficulty with maintaining full enteral feedings, arachidonic and docosahexaenoic acids, which are normally derived in utero from maternal plasma, may also be essential. These fatty acids are vital for normal brain development, myelination, cell proliferation, and retinal function. What are the proven advantages of supplementing formulas with long-chain polyunsaturated fatty acids? Scaly dermatitis, alopecia, thrombocytopenia (and platelet dysfunction), failure to thrive, and increased susceptibility to recurrent infection. To prevent and treat fatty acid deficiency, 4% to 5% of caloric intake should be provided as linoleic acid and 1% as linolenic acid. Dietary nucleotides may play a role during early neonatal life in the desaturation and elongation of essential fatty acids, which are necessary for brain and retinal development. The addition of nucleotides to formula (simulating the composition of breast milk) may be especially important during early development. Nucleotides are present in relatively large amounts in human milk, and several studies have suggested an important role for nucleotides in immune function, gastrointestinal function, and lipoprotein metabolism. Breast milk is protective against infection and may reduce the incidence of adult chronic diseases.

Although a nonrigid group has been described hair loss female discount finasteride 1 mg amex, it is not yet known whether this is a different biochemical process hair loss video cheap 5mg finasteride mastercard, or an earlier stage of the same process hair loss 7 weeks pregnant cheap finasteride 1mg line. A contracture of the muscle actually takes place and, if the process is not aborted, oedema of the muscle, and subsequently ischaemia can develop. Tachypnoea occurs in a spontaneously breathing patient, whilst in the paralysed patient there is an apparently increased requirement for neuromuscular blockers. Severe acidosis may have been responsible for the Emergency conditions arising during anaesthesia M Malignant hyperthermia quantities, particularly after the use of suxamethonium. Hyperkalaemia and cardiac arrest has been reported after inhalation anaesthesia alone in both Duchenne (Chalkiadis & Branch 1990) and Becker muscular dystrophies (Bush & Dubovitz 1991). Myoglobin may be detected in the blood and urine almost immediately, but its transient appearance means that its presence is frequently missed. Often, the maximum blood concentration will not be seen until the following day, and levels will remain elevated for several days after this. Under these circumstances, Ellis et al (1990) recommended that attention is paid to the following features. However, it also means that there is an increase in the number of aborted or doubtful cases. M Malignant hyperthermia 566 Emergency conditions arising during anaesthesia diagnosis the syndrome will be aborted by the first measure in 4 (below). If necessary, follow with an infusion of glucose 20% 1 litre, with insulin 100 u, and infuse at 2 ml kg­1 h­1. If there is obvious myoglobinuria, give iv fluids, with mannitol or furosemide (frusemide) to reduce the possibility of renal failure. They may be indicated in the severe case, particularly if there is cerebral oedema.

However, it is now known that an increase in masseter muscle tone may be a normal response to suxamethonium. In a study of 50 healthy patients, the majority showed myotonia which lasted for less than 100 s (Leary & Ellis 1990). In about 40%, the maximum tone was greater than 500 g, and in 1% it was greater than 1 kg. On occasions, the rigidity can last several minutes, and may be such that the jaw can barely be opened. A similar situation was found in studies on eight patients having squint surgery (Saddler et al 1990). At the same time, an increase in tension, but to a lesser degree, was found in the adductor pollicis muscles. This hypertonus is more likely to occur in young patients, particularly if a volatile agent has been given before the suxamethonium. The masseter spasm may be associated with ventricular arrhythmias and myoglobinuria. This may explain the localisation of the spasm to the jaw muscles (Fletcher 1987). Two studies claim that masseter spasm occurs in as many as 1% of children after halothane induction followed by suxamethonium administration (Schwartz et al 1984, Carroll 1987). Littleford et al (1991), in a study of 42 000 anaesthetics over a 10-year period, found that it occurred in 0. This situation, which is rare, must be differentiated from a mere increase in muscle tone, which is common among children (van der Spek et al 1987) and passes off fairly rapidly. This had not been accepted as diagnostic by a number of workers in the field, and an incidence as high as this was therefore disputed (Ellis & Halsall 1986). Using caffeine and halothane contracture tests, other workers have found the incidence to be between 40% and 60%. In the mid-1980s, the profession was divided as to whether or not surgery should be continued if masseter spasm occurred. This author believes that surgery should be continued, with close metabolic and acid­base monitoring, and should only be stopped if signs suggest an abnormal metabolic response, or other signs of muscular involvement occur. A 25 year old involved in major trauma developed masseter muscle spasm after suxamethonium, when tracheal intubation was performed for resuscitation. Peripheral muscles are usually flaccid, and there is no response to nerve stimulation.

The bone scan is less suitable for evaluating the extent of a tumor, since the activity uptake extends beyond the tumor margins. The bone scan is the simplest and most cost-effec- 4 Some tumors form a matrix, a cell-free intercellular ground substance that mineralizes, i. Typical matrix-forming tumors are: osteoblastoma, osteoid osteoma, osteosarcoma (matrix = bone ground substance or osteoid), osteochondroma, enchondroma, chondromyxoid fibroma, chondrosarcoma, (matrix = cartilaginous ground substance), desmoplastic fibroma, fibrosarcoma (matrix = collagen fibers), fibrous dysplasia (matrix = mixed: osteoid and collagen fibers). The osteosarcoma can also produce a mixed matrix (osteoid, chondroid or collagen fibers). Depending on the prevailing matrix type the osteosarcoma can be described as osteoblastic, chondroblastic, fibroblastic, etc. The following tumors and tumor-like lesions do not form a matrix: simple bone cyst, aneurysmal bone cyst, giant cell tumor, Ewing sarcoma. The pattern of radiologically visible matrix calcification can provide an indication of the underlying, matrix-forming tumor type. Depending on the degree of mineralization, the osteoid shows a cloud-like or solid, or even ivory-like appearance on the conventional x-ray. Benign lesions such as the osteoblastoma can also show a peripheral, seam-like zone of brightening, since the tumor matrix in these immature proliferating areas has not usually yet mineralized. The extent of mineralization associated with osteosarcomas varies and can range from usually ill-defined, cloud-like areas of condensation to highly sclerosed, ivory-like zones. In fibrous dysplasia the formation of irregular metaplastic fibrous bone is accompanied by collagen fiber production. Characteristically, the mineralization in such cases leads to a relatively uniform increase in density and produces the groundglass opacity on the x-ray that is typical of fibrous dysplasia. If enchondral ossification occurs at the periphery of cartilaginous tumors, which often appear to have a lobular structure on histological examination, then this non-tumorous bone calcifies, producing radiologically visible ring- or arc-shaped condensation tive method for detecting bone metastases (including skip metastases), and should be implemented if there is any suspicion of a malignant tumor or to rule out multiple lesions. Ultrasound Ultrasound is primarily suitable for the primary evaluation of soft tissue processes, especially for distinguishing between fluid-containing and solid tumors. Ultrasound is also suitable for the initial scanning for metastases in the abdomen. The extent of a tumor, particularly in the vicinity of a joint, in the pelvic area and the spine, can be determined very precisely by recording transverse slices. In critical cases however (particularly in establishing whether the tumor has penetrated into the joint or not), the inability to record sagittal and frontal slices is a drawback. Computer-assisted reconstruction in one of these planes is only helpful if the resolution (which depends on the slice thickness) is good 591 4. The data from the two examinations are digitally combined to produce an exact anatomical assignment of the findings. Angiography is indicated particularly in cases of vessel bridging or preoperative embolization. In view of its superior performance in tissue A biopsy must be arranged for all lesions that cannot be clearly diagnosed on the basis of imaging investigations or if malignancy is suspected. The fine needle biopsy only allows a tiny cylinder to be removed, which is not sufficient for confirming the diagnosis of an unclear tumor, which often shows a heterogeneous structure. But fine needle biopsy can, at least, usually indicate whether a metastasis or primary tumor is involved. It is also important to mark the entry site so that the contaminated biopsy channel can subsequently be removed with the tumor. A standard trephine (or core trephine) used for removing broken screws is not suitable for this purpose since it transports the drilled bone inwards and crushes the withdrawn cylinder. In addition, the biopsy material is thermally damaged as a result of the build-up of heat, rendering it almost impossible to evaluate. More appropriate instruments are special trephines that transport the bone fragments outwards and that incorporate a special device for ejecting the cylinder.

The derotation is much better in children who are able to hair loss in teens buy 1mg finasteride walk than in severely disabled children [9] hair loss usa water purchase finasteride 1mg with visa. Gait investigations have also shown that the load transfer differs greatly during an intoeing gait compared to hair loss cure october 2012 discount 5 mg finasteride overnight delivery a normal gait [10]. If the increased anteversion were offset by increased tibial torsion, then the impulse for further correction of anteversion would no longer be present since the feet strike the ground in parallel. Various investigations have shown a positive correlation between femoral and tibial torsion [14]. The problem, however, lies in the fact that the knee is rotated in an intoeing gait and is not aligned with the direction of walking. Although there are no scientific investigations on the consequences of this kind of deformity, it is striking that adult patients with this condition tend to consult the orthopaedist with knee problems relatively frequently. On the other hand, the increased anteversion does not have any long-term consequences for the hip [18]. No increased incidence of osteoarthritis of the hip has been observed, for example. And this is logical, since the internal rotation of the femur during walking produces a physiological position at the femoral neck. In contrast with the increased anteversion of the femoral neck, retroversion is a sign of pre-arthritis [8, 18] and requires 551 4. As already mentioned, the impulse to correct the anteversion is lacking in increased lateral torsion of the tibia. We consider that a lateral tibial torsion of 40° or above requires correction [6, 16]. Up until the age of 8 we await the outcome of spontaneous developments, although the lateral torsion tends to increase rather than decrease. This is a minor and safe procedure associated with minimal morbidity and gives the child the chance to derotate the femoral anteversion during the pubertal growth spurt. Efficient derotation is possible by this point only if the fibula is osteotomied as well. Fixation is more complicated and spontaneous derotation of the femur can no longer be expected. An intoeing gait would then persist in such cases unless the torsion of the femoral neck were also corrected, which ­ when performed bilaterally ­ is quite an elaborate procedure. This occurs regularly in connection with a genu varum, but is very atypical in clubfoot. The internal rotation of the foot is not caused by the medial torsion of the tibia, but rather by the foot position itself. Consequently, the externally rotating tibial derotation osteotomy is rarely indicated in clubfoot. In fact, an increased lateral torsion is generally present despite the inward-facing position of the foot. Only in very rare cases is correction indicated at this site, and the correction must usually be performed on the foot itself (Chapter 3. We therefore consider that the supramalleolar tibial derotation osteotomy is indicated if there is a lateral torsion of more than 40° or a reduced tibial torsion of 5° and under. They occasionally occur after the start of walking, particularly in children who start walking at a very early age, i. In such cases this varus axis can take on dramatic proportions at the age of 1­2 years. It is usually associated with pronounced medial torsion of the tibia, making the genua vara appear even more extreme. The prognosis for these idiopathic cases of genu varum is very good in small children provided there is no underlying pathology. A recent investigation has shown that the risk of progression only applies if the varus is located predominantly in the tibia rather than the femur [1]. This condition involves a necrosis in the area of the proximal medial tibial epiphysis, and possibly the medial distal femoral epiphysis. In addition to the infantile form, there is a juvenile variant, which can involve the spontaneous formation of a medial bridge across the epiphyseal plate and necrosis of the proximal medial tibial epiphysis. Rickets can be related to the diet or occur as a vitamin D-resistant condition (Chapter 4. A varus position with an intercondylar distance of more than 2 cm should be corrected, particularly if a rotational deformity is also present in the lower leg.
