While in Vienna tion was used primarily in the treatment of fresh he became aware, for the first time, of the sub- fractures. This small bursa was to become the theme of his life’s work; and from this theme many side excursions were destined to be taken. Although in subsequent years many other interests took of his time and stamina, nevertheless he pursued the study of the subdeltoid bursa and its environs throughout his entire life, the culmination being a book entitled The Shoulder, which was published in 1934. He pursued these studies with great tenacity; he made and recorded many original observations and became an authority in the new fields. In all his undertakings he worked to capacity; he left no stone unturned, he went deeply into the subject. These traits were first exhibited in 1895 when he was appointed assis- tant in anatomy at the Harvard Medical School. For the next several years he studied in minute detail the subdeltoid bursa and its pathology in the dissecting room and on postmortem specimens. This study made him aware of the clinical signi- Ernest Amory CODMAN ficance of this region of the shoulder joint. He 1869–1940 applied this knowledge in the outpatient clinics of the Massachusetts General Hospital, when he was In every generation there are a few outstanding appointed surgeon to outpatients in 1899.

Broad complex tachycardia Little harm results if supraventricular tachycardia is treated as Treat broad complex tachycardia as sustained ventricular tachycardia** a ventricular arrhythmia; however safe provera 10 mg, the converse error may have serious consequences buy provera 5mg with visa. The first question that determines management is whether a palpable pulse is present cheap 5mg provera visa.

London: Resuscitation Council (UK), 2000 If the serum potassium concentration is known to be low an infusion of potassium and magnesium should be given. If the potassium concentration is unknown it must be measured immediately. Amiodarone is again recommended as the drug of first choice to stop the tachycardia; lignocaine (lidocaine) remains an alternative. With most patients there should be time to consult expert help to advise about management. Synchronised cardioversion should preferably be attempted after Overdrive pacing is a technique whereby the allowing one hour for the amiodarone infusion to take effect.

Narrow complex tachycardia A narrow complex tachycardia is virtually always supraventricular in origin—that is, the activating impulse of the tachycardia passes through the AV node. Supraventricular 22 Management of peri-arrest arrhythmias tachycardias are, in general, less dangerous than those of ventricular origin and only rarely occur after the successful treatment of ventricular tachyarrhythmias. Nevertheless, they are a recognised trigger for the development of ventricular fibrillation in vulnerable patients. If the patient is pulseless in association with a narrow complex tachycardia, then electrical cardioversion should be Narrow complex tachycardia attempted immediately. As in the treatment of any serious rhythm disturbance, oxygen should be administered and intravenous access established. At this stage it is important to exclude the presence of atrial fibrillation. This is a common arrhythmia occurring before cardiac arrest and often in the post-resuscitation period. In atrial fibrillation the ventricular response is irregular, unlike the regular ventricular pattern seen with other rhythms that arise above the AV junction. At faster ventricular rates it may be difficult to determine whether the rhythm is regular because the variation in the R-R interval, which is a feature of atrial fibrillation, becomes less pronounced. Atrial fibrillation may Pulseless (heart rate Narrow complex Atrial usually >250 beats/ tachycardia fibrillation then seem to be regular and the distinction can only be made minute) if an adequate rhythm strip is examined carefully for variability Synchronised DC shock* If not already done, give oxygen Follow AF algorithm in the underlying rate.

There were 45 children in the ibuprofen arm and 39 children in the placebo arm buy provera 10 mg amex. Headache response at 2 hr was significantly higher in the ibuprofen arm (76% of attacks) compared to placebo (53% of attacks order provera 5mg without a prescription, p ¼ 0 purchase provera 2.5mg with amex. Only one child in the ibuprofen arm needed rescue medication compared to 15 in the placebo arm (p < 0 order provera 2.5mg visa. However generic provera 10mg otc, caution must be used in the use of nonsteroidal anti- inflammatory drugs (NSAIDs) due to the risk of rebound headache (otherwise known as transformed migraine), which can occur with perhaps as little as two to three doses of medication per week. There are several studies examining the efficacy and tolerability of sumatriptan in children under 12 years of age. A total of 67 children have been reported in open- label trials utilizing sumatriptan subcutaneous injection. In both studies, sumatrip- tan injection was fairly well tolerated and effective. Sumatriptan nasal spray has also been investigated in children and adolescents. An open-label, retrospective study of 10 children aged 5–12 years found sumatriptan nasal spray well tolerated and effec- tive. A randomized, double-blind, placebo-controlled crossover trial of 14 children aged 6–9 years demonstrated that sumatriptan nasal spray 20 mg=dose was effective and well tolerated. Collectively, these studies suggest that sumatriptan given subcu- taneously (0. There is a building collection of clinical evidence from large multicenter, randomized, double-blind, placebo-controlled, parallel group trials that assess the efficacy of triptans specifically in adolescents over 12 years of age. In a study of 234 Pearlman 302 patients comparing sumatriptan 25, 50, and 100 mg tablets to placebo, the primary endpoint of 2 hr headache response failed to reach significant differences from placebo (49%, 50%, 51% compared to placebo 42%). All three doses of suma- triptan were statistically significant compared to placebo at 3 (65%, 64%, 69% compared to 45%) and 4 hr (73%, 73%, 74% compared to 53%), however. The 50 mg dose was significant compared to placebo at 90 min (47% compared to 30%), while the 25 mg (38%) and 100 mg (38%) doses were not. Two things to note about this trial are that the placebo rate was quite high compared to those normally observed (30–40%) in most adult triptan trials. In a large randomized, double-blind, placebo-controlled study of sumatriptan nasal spray, 5, 10, and 20 mg vs. Subjects were required to self-administer study medication at home under the supervision of their parents. Only the 5-mg dose was found to be statistically significantly superior to placebo (p < 0. The 10- and 20-mg doses did not statistically differ from placebo, although there is a numerical trend favoring active treatment. This study differs from adult trials in that there was no apparent dose–response curve noted. A large study of rizatriptan used similar inclusion criteria as the sumatriptan nasal spray study reviewed previously. In addition, patients were instructed to take study medication within 30 min of onset of a moderate=severe attack. The primary endpoint of 2-hr pain relief was achieved in 66% of subjects treated with rizatriptan 5 mg compared to 56% for placebo, which was not statistically significant. Posthoc analysis found that for those attacks treated on weekdays, the response rates were 66% for rizatriptan and 61% for placebo. However, for those attacks treated on weekends, the response rates were 65% and 36%, respectively. The response rates were essentially the same for rizatriptan, but the placebo response rate for weekends was much lower than during the week. To sum, there have been over 1650 subjects between 12 and 18 years involved in clinical trials published so far with an excellent tolerability and safety record. The evidence regarding efficacy has been marred by very high placebo response rates. This does not imply that the medications are not effective but demonstrates the difficulty in studying pain in this population. Further studies are ongoing with efforts to correct the shortcomings of prior studies. Treatment Algorithm The use of migraine-specific medications should be considered early in the course of treatment so as not to deny significant treatment benefits.

Lying down or sitting in a chair or car for some reason caused his back to become stiff and hurt even more buy provera 2.5mg otc. Even though he would get up and stretch periodically generic 10 mg provera, by the end of each work- day generic provera 2.5mg mastercard, he was close to tears from the pain discount 10mg provera otc. He was ready to give up his job to become a construction worker or anything that was less sedentary and more physical discount provera 5 mg otc. Every morning, he awoke with increased back stiffness, and the pain in the lower left quadrant of his back was excruciating. Massage therapy felt great but did not afford him any long- lasting relief. Acupuncture lessened the sensation of pain, but the relief only lasted for a few hours. His doctor examined Brad again and discovered that his patient was, indeed, “tight. They helped until Brad Do You Have Unexplained Back, Neck, or Joint Pain? Brad tried a number of other things in an effort to help himself, includ- ing wearing magnets. He dropped a few pounds because he was afraid he was getting sciatica like his uncle whose condition had improved with weight loss. But when he discussed the problem with his Uncle Ben, they both agreed Brad’s pain didn’t seem the same since it didn’t radiate down his leg. Brad now understood why his own doctor hadn’t suggested sciatica as a diagnosis. The only relief for Brad, besides the anti-inflammatory med- ication, came from physical exercise. Eventually, Brad visited another orthopedic surgeon who prescribed strong pain medication. Brad took this medication for a while but soon stopped for fear he would become like his father. Brad remembered his dad, who’d also had back pain, living on pain pills for most of his life. Brad was afraid of becoming addicted like he thought his father might have been. Finally, Brad considered quitting work and going on disability, but he knew he would have a big problem getting disability coverage. How was he going to explain to the insurance company that he couldn’t work but he could still play tennis, exercise, and be extremely active? Fortunately Brad’s uncle described his nephew’s problem to a friend with whom he played cards and who happened to be a retired physical ther- apist. Using the Eight Steps This is a sampling of Brad’s notebook, which finally led to a correct and admittedly unusual diagnosis. Back Pain • Quality and Character: One-sided lower back pain that feels like a hot poker. The only other possible cause of this sprain that happened about the same time was that I was dating this girl, Lydia, and we were into some heavy-duty “sexual gymnastics. Pain killers and anti- inflammatories help, but if I stop taking them, the pain returns. Step Four: Do a Family Medical History and Determine If You Have or Had Any Blood Relatives with a Similar Problem. My father was always complaining about low back pain but I think he just liked to complain and this was a great excuse for him to take prescription drugs. Step Five: Search for Other Past or Present Mental or Physical Problems. Other than the tennis elbow I developed two years ago which got better, and other muscle strains and sprains from playing football and other phys- ical activities, I have been fairly healthy other than an occasional cold. About eight months ago, after I started dating Lydia, I may have caught something from her. She had some gynecological problems which she said she took care of, but I developed a horrible burning sensation when I urinated. I went to a urologist who gave me some pills and eventually the burning resolved. Around the same time, I also had an episode of red-eye, which my eye doctor said was conjunctivitis. Sometimes I have ulcers in my mouth, but I forgot to mention this to my doctor or in Step Five.
