In most cases buy 60 mg alli weight loss guide, bedside ultrasound should be used to rule in a suspected fracture with negative radiographs order alli without prescription weight loss 2016, rather than to rule out a fracture discount alli 60mg overnight delivery weight loss pills that are fda approved. Case reports of detection of occult fracture by ultrasound include a child with a spiral femur fracture and an infant with a clavicle fracture, both of which were con- ?rmed by repeat delayed radiography 6 to 8 days later (8). There has also been some research in the area of detecting scaphoid fractures by ultrasound in patients with negative x-rays. The diagnosis of scaphoid fracture by ultrasound is technically challenging, with only moderate sensitivity (17, 20). Given the high potential liability of scaphoid fractures, conventional management of suspected scaphoid fracture with a negative radiograph is unlikely to be altered by bedside ultrasound at this time. Bedside ultrasound can expedite fracture reduc- tion and minimize the patient’s exposure to ionizing radiation. Appearance Simple joint e?usions appear as an anechoic area within the joint capsule. The ?uid associated with an e?usion is closely aligned with the bone cortex itself. However, in the case of bursitis, the increased ?uid in the bursa may be anechoic, mimicking an e?usion. By having the fracture should ?rst be visualized using a high- knowledge of the anatomical location of bursas in the joint frequency linear probe both in a long and short axis. It will in question and by recognizing that an e?usion typically lies appear as a break and displacement in the bright linear cor- directly adjacent to bone, the sonographer should be able to tical surface, and both the degree of separation and displace- distinguish between the two processes (18). After the ?rst sion, such as a hemarthrosis in which the blood has begun to reduction attempt, the same area should be scanned to deter- clot, may appear hypoechoic, or brighter than a simple mine if the reduction was successful. If there is still signi?cation separation or Arthrocentesis displacement, another reduction attempt can be made imme- Sonographically guided joint aspirations use similar diately and reassessed for adequate alignment. Rather than approaches as traditional joint aspirations but allow for placing a cast or splint and sending the patient for greater accuracy. The actual site of needle insertion will not a postreduction x-ray, a bedside ultrasound can visualize the di?er from a traditional technique, but the ultrasound image alignment of the fractured segments in real time and allow for can help more accurately guide that needle to the e?usions. The probe should be held in a position that does not interfere with the needle insertion site yet allows for visualization of the Joint e?usions needle tip. For Sonography also has a role in identifying and assisting with example, if attempting to aspirate an elbow e?usion, the the aspiration of joint e?usions. Although some joint e?u- probe can be held transversely in the antecubital fossa while sions may be readily diagnosed clinically, some joints such as a lateral approach at aspiration is attempted. Also, patients with question should ?rst be imaged in multiple planes before a di?cult body habitus may not lend themselves to an easy the best approach is decided. Ultrasound can only determine the Hip e?usions presence or absence of an e?usion; it cannot di?erentiate Multiple studies and case reports have demonstrated the between infectious or in?ammatory e?usions. Although utility of ultrasound in identifying hip e?usions and guiding ultrasound cannot determine the nature of the e?usion, it arthrocentesis (22–28). Fluid around the hip joint is usually 353 can assist in the aspiration of ?uid for analysis. Knee e?usions Knee e?usions can be imaged by ultrasound in cases where it is di?cult to ascertain whether an e?usion is present or if ultrasound guidance for an arthrocentesis is desired. The linear probe should be held in the sagittal plane, just superior to the patella, with the leg extended. This will allow for adequate visualization of the knee joint and for a lateral approach to arthrocentesis under ultrasound guidance if indi- cated. The sagittal view is obtained by a lower-frequency probe to achieve the appropriate depth. When attempting to determine whether a clinically signi?cant hip e?usion is present, both hips should Tendon injury be scanned, comparing the symptomatic side to the contral- There are several ?ndings indicative of a tendon tear. If the di?erence is greater than 1 to 3 mm, or if the case of a partial tear, there may be a hypoechoic irregularity in stripe is greater than 6 mm in the symptomatic side, then an the usually hyperechoic organized linear structure of the e?usion is present. Partial-thickness tears need to be di?erentiated ligament, which appears as a hyperechoic structure in front of from anisotropy by realigning the probe so the sound beam the femoral cortex. An e?usion will displace the iliofemoral is perpendicular to the area of interest, to ascertain whether ligament from the femoral neck by a hypoechoic or anechoic the irregularity is an artifact or true pathology. One pitfall is the potential to mistake trochanteric more sensitive at detecting full-thickness tears, although their bursitis for an intra-articular e?usion. Nonvisualization of the 354 choic ?uid collection associated with trochanteric bursitis is tendon, especially when compared to the normal side, is 21:19:12 25 Chapter 25: Emergency Musculoskeletal Ultrasound A B Figure 25. In some instances, the end of the retracted tendon may appear as a blunt or mass like structure. A ?uid collection or hypoechoic shadowing may also be present at the site of injury and can help aid in the diagnosis. The diagnosis of subtle abnormalities may be aided by scanning the contralateral side and by scanning during motion of the joint. Ultrasound has been found to identify tendon injuries in 97% of patients, as compared with physical exam, which identi?ed 86% of injuries (29). Ultrasound can also be a useful adjunct when the physical exam is limited to swelling, Figure 25. Tenosynovitis the clinical ?ndings of tenosynovitis can be con?rmed by directly visualizing ?uid surrounding the tendon sheath. Fluid or pus in When faced with a patient with a swollen painful ?nger, the tendon sheath appears anechoic and can clearly be seen di?erentiating between cellulitis and infectious tenosynovitis outlining the tendon.

It ends by dividing into one proper digital branch for the great toe order alli once a day weight loss low carb, and three common plantar digital branches discount generic alli canada weight loss 3rd trimester. Branches arising from the trunk of the medial plantar nerve supply the skin of the medial part of the sole buy 60 mg alli free shipping weight loss pills 7 days. The skin on the medial side of the great toe is supplied by the proper digital branch to this digit. The frst (most medial) common plantar digital nerve divides into the proper digital nerves that supply the skin on the adjacent sides of the great toe and second toe. The superficial branch runs distally and ends by dividing into two plantar digital nerves. The medial one divides into two branches that supply the adjacent sides of the fourth and ffth digits. Some branches arising from the trunk of the nerve supply the skin of the lateral part of the sole. The skin on the lateral side of the little toe and the contiguous sides of the fourth and ffth toes is supplied by the corresponding digital branches. The area of supply also extends on to the anterior and posterior aspects of the leg. The skin of part of the dorsum of the foot is supplied by the deep peroneal nerve through its medial terminal branch. This branch runs forwards on the dorsum of the foot along with the dorsalis pedis artery. It divides into two dorsal digital nerves which supply the adjacent sides of the great toe and the second toe. It then divides into medial and lateral terminal branches that descend across the ankle to reach the dorsum of the foot. The medial branch gives one dorsal digital nerve to the medial side of the great toe and another to the ad- jacent sides of the second and third toes. The lateral branch gives one dorsal digital nerve to the contiguous sides of the third and fourth toes and another to the adjacent sides of the fourth and ffth toes. The lateral terminal branch also supplies the skin on the lateral side of the ankle. The veins of the lower limbs can be divided into deep and superficial veins (like those of the upper limbs). The superfcial veins lie in the superfcial fascia and many of them can be seen through the skin. They are also connected to deep veins through perforating veins that pass through deep fascia. The anterior and posterior tibial veins Chapter 10 ¦ Cutaneous Nerves, Veins and Lym phatic Drainage: Front. These veins accompany the corresponding arteries and (by and large) have tributaries corresponding to the branches of the arteries. The veins accompanying the other arteries of the lower limb are in the nature of venae comitantes. The dorsal and plantar surfaces of the foot are covered by subcutaneous venous plexuses. Along the sides of the foot, there are medial and lateral marginal veins that communicate with both the plantar and dorsal venous networks. These veins are continued into two large superfcial veins, the great (or long) saphenous vein; and the small (or short) saphenous vein respec- tively. The great (or long) saphenous vein is a continuation of the medial mar- ginal vein of the foot. It ascends into the leg, a little in front of the medial malleolus and lies for some distance on the medial surface of the tibia. Ascending on the medial side of the leg, it crosses the medial side of the knee joint, and ascends on the medial side of the thigh. In the upper part of the thigh, it passes somewhat laterally and passes through an aperture in the deep fascia (saphenous opening) to end in the femoral vein (10. The great saphenous vein receives numerous tributaries from the front the foot and back of the leg, and from the front of the thigh. Just before it pierces the deep fascia, it receives the superfcial epigastric, superfcial circumfex iliac and external pudendal veins. It also receives the anterior cutaneous vein of the thigh which drains the lower part of the front of the thigh. Just below the knee it receives the anterior vein of the leg, and the posterior arch vein. Over the dorsum of the foot the great saphenous vein receives the medial marginal vein of the foot. The great saphenous vein is connected to the deep veins of the leg and thigh through a number of perforat- ing veins that are mentioned below. In emergencies (requiring transfusions), when the vein cannot be seen, it is useful to remember that this vein is constantly located immediately in front of the medial malleolus. In such operations the direction of the segment is reversed, so that valves do not interfere with blood fow. The small (or short) saphenous vein is a continuation of the lateral marginal vein of the foot. It ascends behind the lateral malleolus, and runs upwards along the middle of the back of the leg. Over the lower part of the popliteal fossa, it perforates the deep fascia and ends in the popliteal vein, a few centimeters above the knee joint (10. The perforating veins (or perforators) are so called, as they perforate through the deep fascia. Valves in them allow blood fow from superfcial to deep veins, but not in the reverse direction (10. Similar communications with deep veins exist where the great and small saphenous veins end in deep veins. A perforator that connects the great saphenous vein to the femoral vein is present in the lower part of the adductor canal (Number 1). A perforator present just below the knee connects the great saphenous vein, or the posterior arch vein, with the posterior tibial vein (Number 2). There are a number of perforators in the lower one third of the leg (number 4, 5, 6). Venous Return from the Lower Limb Venous blood from the lower limbs has to ascend to the heart against gravity. The atmospheric pressure within the thoracic cavity is negative and this tends to suck blood in the venous system towards the heart.
The thermal imbalance was accompanied by not only a propor- tionate increase in potassium excretion but by an increase in sodium intake: the workers received salted food and often expressed the need for sucking salted candies buy alli pills in toronto weight loss 50 pounds. Although space does not permit a presentation of my chemical and thermal observation buy alli canada weight loss 7 days, I can say that the workers transmuted about 0 discount alli 60mg with visa weight loss programs. This, then, was the means by which they main- tained their thermal equilibrium, classical theories notwithstanding. The Carbon Steel Corporation of Europe conducted a study (1959) of the behavior of workers who operated ovens used for the heat treatment of steel. The mea- 36 Biological Transmutation sured values obtained in that investigation coincide with those noted in the Sahara. In both cases, however, the doctors who collected the data and the professors who attempted to interpret it were unsuc- cessful. This is further proof that over-specialization often becomes indoctrination—it blinds people to the obvious. One result of my experience in the desert is that I have been able to determine the energy needed for the reaction Na + O > K. It is about four electron volts (4eV) for one oxygen nucleus linked to an Na nucleus (about 3500 times as much as the chemical reac- tion of physical atomic fusion). This energy (4eV) may be furnished by short ultra-violet radiation (wave length 3000 Angstroms or 0. Further checking shows that the endothermic transmutation Na + O > K (the defense reaction of a body threatened by hyper- thermy) is due to the imbalance of Na/K. The hormone cortisol tends to maintain that balance as long as it remains in the vicinity of 1. It is not possible to go into the details of many other observations made on the isotopes of potassium. I mention only that these enabled me to understand why some tables of atomic mass cannot be used in biology; the isotopic composition of organic potassium is different from that of the mineral potassium dealt with in the tables with a divergence bearing on the frst decimal. The whole question of biology is so complex that on the biologi- cal scale, nuclear physics is too simple. Further, the data available on an isotope nucleus is not useful because this nucleus is known to us, in physics, only as an entity unto itself and values given are merely resultant averages. We must recognize that a nucleus is a heterogeneous entity of masses and energies: the median values of atomic physics are thus of no help. Chapter 4 Magnesium, Phosphorus, and Calcium I will say even less about magnesium (Mg) although the observa- tions here are also numerous and varied. We have seen the birth of magnesium from calcium (dolomites, saltpeter): Ca – O > Mg. Plants take about 20-50 kg Mg-metal per hectare each year yet no magnesium fertilizer is given. Then Mg increases enough so that salt water must be given to permit the body to restore its equilibrium. Data recorded in the Sahara allowed me to make similar obser- vations: the average excretion per day for a period of six months ex- ceeded intake by 117 mg (Mg-metal) with the maximum during the frst week of September when the fgure reached 222 mg. Where more of a substance is excreted than is ingested, the pro- portion can be considered to be negative. With this in mind, we have noted that every negative balance of Mg is accompanied by a nega- tive proportion of P and Ca. Over a span of six months, fve workers displaying a positive balance of Mg simultaneously showed a positive balance of P and Ca. This can be represented by the following equation forms: Mg + O > Ca and Mg + (Na – O) > P I have already mentioned that 2 12C > Mg. This was verifed in24 a particle accelerator (1961) and would seem to call for a complete reconsideration of the origin of hydrocarbons. Conclusion A purely technical study of the foregoing reactions cannot be made in a few pages because it cannot be supported by any existing meth- ods. When we say that N will give Si or (C + O), we should thereupon2 be able to derive all the combinations of stable isotopes that are pos- sible and only these. We have two stable isotopes of nitrogen (14N and 15N), two of carbon (12C and 13C), three of oxygen (16O, 17O, and 18O) and three of silicon (28Si, 29Si, and 30Si). Because N is the origin, we can have 2 only the following combinations: 2(14N) or 28Si = 12C + 16O 14N + 15N or 29Si = 12C + 17O or 13C + 16O 2(15N) or 30Si = 12C + 18O or 13C + 17O the only apparent exception is that there is no C + O, the sum13 18 of which would give a mass number of 31. This is an impossibility and does not appear because the maximum is 2(15N) with a mass number (A) of 30. Further, there are no nucleons that permit us to derive 13C and 18O from nitrogen. It can also be seen that if 2C > Mg, the above mentioned stable isotopes—12C and 13C—can be combined to give 24Mg, 25Mg, and 26Mg. In the case of sodium (23Na), which has no isotope, its combina- 39 40 Biological Transmutation tion with 16O, 17O, and 18O gives 39K, K , and K again valid. We adjust by writing: 28Si < N < (C + O) < 214N 2 N is the stable molecule of nitrogen. It would be a mistake, however, to take for the mass of (C + O), the sum of the masses of 12C and 16O. Similarly, 214N is an arithmetical operation without value, be- cause two atoms of nitrogen form a linked unit which includes en- ergy that does not exist in 14N. This shows why calculations from the data of nuclear physics are not transposable for biological use, the exact masses of both N and2 (C + O) being unknown. It is likely, in addition, that organic atoms are different from mineral ones, making their masses different also. A precisely known mass, like that of 28Si, cannot be compared, in biology, with the sums of the masses of 12C and 16O, because the difference in masses points up the energy liberated by the fusion of these two nuclides. Suppose that this energy is equally divided among the 28 nucleons that are Conclusion 41 together. In this case, the energy-total given by the classical calcu- lation in nuclear physics has a statistical value only; for the total linking-energy is not a product of 28 equal elementary energies, but of three energetical values: 1. The third energy value is a feeble linking-energy between the O and C groups and is only approximately one-mil- lionth the value of the other two. The actual macro-physics of the atom is on a scale that does not permit the exploration of the inner constitution of the nucleus in a manner that is precise enough. It is interesting to note, however, that while the internal linking-energy of oxygen with 16 nucleons totals a little more than 127 million electron volts, only 4 electron volts are suffcient by contrast for a sodium nucleus to couple with an oxygen nucleus. There is no common measure: in biology the situation is differ- ent from that found in atomic physics. Similarly, if these transmutations are not observed in chemistry, it is because the energies used are too feeble. This phenomenon gives up an energy about 3500 times feebler than resulting from the nuclido-biological reac- tion that joins an oxygen atom to a sodium atom! Conclusion the evidence that I have presented (graphically represented in the diagram below) shows clearly that we are in the presence of a hitherto unknown property of matter: biological transmutation, a 42 Biological Transmutation phenomenon that is completely different from the atomic fusions or fssions of physics. Na + + O H K Mg + + H O Ca As a result, all sciences will face a thorough-going re- examina- tion.
