Consequently knee pain treatment guidelines purchase generic azulfidine from india, it can rarely cause liver function test abnormalities, particularly with concomitant statin use. The omega-3 fatty acid supplements are generally safe, with common side effects including nausea, gastrointestinal upset, and a "fishy burp," which can be minimized by ingestion at bedtime or with meals. High doses of omega-3 fatty acids may prolong bleeding time, requiring periodic monitoring of patients taking anticoagulants. The full set of guidelines was initially published in 2001 and revised in 2004 to include findings from the five major clinical trials published in the interim. Such tests include assessment of ankle-brachial index, carotid intima-media thickness, coronary artery calcium, C-reactive protein, and exercise treadmill testing. Factors that influence more intensive statin therapy in this group include advanced age, multiple or severe risk factors, and metabolic syndrome. Several conditions are associated with hypertriglyceridemia, including obesity, physical inactivity, excess alcohol intake, high carbohydrate intake, insulin resistance (diabetes, metabolic syndrome), certain drugs (corticosteroids, estrogens, beta-blockers), and genetic disorders (familial combined hyperlipidemia, familial hypertriglyceridemia, and familial dysbetalipoproteinemia). The initial treatment priority is to target the underlying cause of elevated triglycerides when possible. Thereafter, specific management strategies for hypertriglyceridemia are outlined as follows: Borderline high triglycerides (150-199 mg/dL): Emphasis is on weight reduction and increased physical activity. Aside from weight reduction and increased physical activity, pharmacologic therapy is recommended. This can be achieved by increasing the dose of statin, or adding fibrates or nicotinic acid as adjunctive therapy. This is accomplished by a very low fat diet (15% of calorie intake), weight reduction, increased physical activity, and the addition of fibrates, nicotinic acid, or omega-3 fatty acids. The distinction between the two is based on the clinical severity and risk of significant morbidity and mortality if the blood pressure is not corrected. In overweight and obese patients, weight loss results in significant blood pressure reduction. It is the most common outpatient diagnosis (1 billion patients worldwide) and contributes directly to 7. Suboptimal blood pressure control is likely to reduce 50% of ischemic heart disease and 60% of strokes, the second and third leading causes of death in the United States. Much of the morbidity and mortality associated with hypertension can be reduced with appropriate medical therapy. This chapter discusses the epidemiology of hypertension, diagnosis and initial therapy, as well as approaches to refractory hypertension. Equipment used to measure blood pressure must be accurate and should be recalibrated on a regular basis. Blood pressure should be measured in the sitting position with the arm resting at heart level.

We should also mention that it is possible to redesign the macromolecular system if the exact mechanism of degradation is known pain treatment medicine generic azulfidine 500 mg. Although in many ways an ideal solution (although immunogenicity can become a problem), this has yet to become a routine approach to stability problems. Often the first thing one does with a biopharmaceutical solution formulation is to select a buffer. For example, a pH can be selected to place the formulation as far as possible from structural changes produced by changes in pH and temperature using a single method. One caveat, however, is that a number of proteins undergo pH-dependent conformational changes as a part of their normal biological functions. For example, the lowering of the pH inside endosomes (sometimes the immediate destination of a protein taken up in to a cell) might induce a structure change that exposes apolar regions, which permits interaction with the endosomal membrane and subsequent release in to the cytoplasm. Furthermore, because so many degradation processes are pH dependent, it may be necessary to compromise in the selection of pH. Some buffers, such as the commonly used Tris (tris-(hydroxymethyl) aminomethane) species shift their pKa by as much as -0. The next step in the formulation of macromolecules (if necessary, as it frequently is) is the selection of excipients to control critical degradation processes. This can be accomplished by using any one or a combination of the methods discussed above. Potential excipients are usually initially tested at high concentrations with concentration dependence studies employed later to define the minimum concentration that can be used to obtain the desired effect. It consists of a collection of carbohydrates, polysaccharides, amino acids, small molecules, detergents, and polymers among other agents. A number of different mechanisms mediated by these compounds can stabilize macromolecular systems. The presence of the stabilizing agent causes the chemical potential (free energy) of the macromolecule to be increased in a manner proportional to its surface area. Because this is an unfavorable process, the effect is to differentially stabilize the native state. For example, the presence of extended polyanion binding sites on many proteins such as growth factors and coagulation factors means that polymers like heparin and dextran sulfate can often have dramatic stabilizing abilities. Direct effects occur through blocking of the protein/protein interactions that are responsible for association processes. Inhibition of protein aggregation by detergents is thought to occur through one or both mechanisms. Because of the presence of disulfide bonds and free thiol groups in proteins, it is sometimes possible to stabilize proteins by the inclusion of a reducing agent to either maintain free thiols in their reduced (and active) form or prevent the formulation of nonnative inter- or intramolecular disulfides which leads to inactive forms.

Usually heel pain treatment video cheap 500 mg azulfidine amex, midaxilla, there is a superficial larger tributary-the thoracoepigastric vein. Many times, this vein can be used as a marker for finding the deeper, more posterior, subscapular vein. The thoracodorsal vein is a tributary of this vein in most instances, with the circumflex and thoracodorsal vein branches combining to form the subscapular vein. On occasions, the thoracodorsal vein may actually merge with the thoracoepigastric vein at a distance of 1 to 2 cm from the axillary vein. Consequently, I do not divide the more superficial thoracoepigastric vein until such time as I have successfully identified the thoracodorsal neurovascular bundle. In identifying a likely candidate for the thoracodorsal vein, the accompanying artery may have a variable relation to the vein; it could be medial, lateral, deep, or superficial to it. The nerve may course along and near the vein, beginning its path alongside the vein immediately inferior to the axillary vein, or it may take a more gradual angled course more medial, emerging from under the axillary vein more medially near the chest wall, near the long thoracic nerve at its more superior extent within the operative field. With a right angle or other clamp for blunt dissection, the tissue plane superficial and/or lateral to the candidate thoracodorsal neurovascular bundle is gently created, stretching the overlying tissues progressively toward the inferior aspect of the operative field. Confirmation of the presence of the nerve comes with a light pinch with the DeBakey forceps, confirming the contraction of the latissimus dorsi muscle. Once the path of the vascular bundle and that of the nerve are confirmed, the thoracoepigastric vein can be ligated and divided in proximity to the axillary vein, taking precautions to maintain a patent proximal branch if the thoracodorsal vein branches from it. Once the neurovascular bundle begins to "dive" more deeply, the dissection need not proceed more deeply. The tissue between this plane along the thoracodorsal neurovascular bundle and the edge of the latissimus dorsi muscle is then divided by using blunt dissection and electrocautery. At this point, the remaining axillary contents are nearly ready to be excised from the axilla. In preparation for this, the tissues immediately inferior to the axillary vein are carefully dissected along its inferior aspect to the depth of the thoracodorsal neurovascular bundle. Also, be aware that many of the lymphatics draining the ipsilateral upper extremity pass along the deep surface of the axilla, just inferior to the axillary vein. These may be apparent but small, tangled or draped (11), and possibly tented anteriorly if the patient is obese, pushed forward by a fat pad posterior to the depth of the thoracodorsal neurovascular bundle. Avoiding these, as long as it does not compromise removal of lymph nodes, may potentially help to reduce the incidence of postoperative ipsilateral upper extremity lymphedema. If a modified radical mastectomy was performed in this context, with the breast in continuity with the axillary contents, the breast or any axillary contents are gently lift anteriorly and medially, exposing the thoracodorsal neurovascular bundle. With the palmar surface of the dominant operating hand facing up, the index finger is placed over the neurovascular bundle and thus protecting it. The medial tissues, including the breast if applicable, are folded back over this positioned hand, exposing the now-visible long thoracic nerve. The tissues are then divided between the long thoracic nerve and the thoracodorsal neurovascular bundle by using electrocautery along the surface of the index finger, thereby avoiding both neural structures.

The high wavelength tail is often used back pain treatment youtube buy 500 mg azulfidine otc, however, to detect proteins during various forms of chromatography. Phenylalanine (Phe) manifests a weak peak with marked vibrational structure between 250 and 270 nm, tyrosine (Tyr) a stronger, pH-dependent multicomponent peak from 250 to 290 nm, and tryptophan, the strongest absorbing side chain (another multicomponent peak) from 250 to 300 nm. In the case of proteins, the broad overlapping nature of these three contributions results in a broad peak centered between 277 and 287 nm (primarily from Trp and Tyr) with weak undulating bumps in the spectrum below 270 nm (due to the vibrational fine structure of the Phe contribution) and a marked shoulder for Trp at approximately 290 nm. Zero-order absorption spectra of four proteins, a peptide and a viral particle (upper panel). When their second derivative is calculated, however, usually six peaks are seen corresponding to the three classes of aromatic side chains (bottom panel). The important point here is that the position (wavelength) of each of these peaks is sensitive to the polarity of their environment. Thus, as the structure of a protein is altered, to the extent that one or more aromatic side chains experiences a subsequent change in its immediate environment, changes in the position of the derivative absorption peaks provide a measure of conformational change (and potentially physical degradation). The folding and unfolding of a protein as induced by temperature, pH, or a potential unfolding agent like urea, guanidinium hydrochloride, alcohols, chaotropic salts, and detergents can be simply followed by this method if their optical properties do not interfere with the measurements. If colors are then assigned to the major components, a map of temperature versus pH displays different colored regions corresponding to different physical states of the protein. These include metals such as copper or iron as well as lanthanides (with Tb and Co the most commonly employed), which can be used as calcium analogues. Fluorescence53,54 Probably the most versatile spectral technique for macromolecular structural analysis is fluorescence spectroscopy. When a chromophore such as the indole side chain of tryptophan in proteins is raised to an excited (singlet) state, rather than return to the ground state through internal conversion processes as in an absorbance measurement, it can do this by the emission of a photon. If this emission is from a triplet state, the process is known as phosphorescence (the combination of the two is called luminescence). For brevity, we will not be concerned with the latter here although the technique of phosphorescence can be quite useful in the analysis of proteins. In the case of fluorescence, the (relatively) long periods of time spent in the excited states (10-3 -10-9 s versus <10-15 s for absorbance) allow various types of interactions with this state. The spectrum of this emission is always at longer wavelengths than the absorption band(s) because prior to emission of fluorescence photons, energy is lost as the excited state returns to its lowest vibrational energy level. As a first approximation, the absorption and emission spectra are mirror images of one another. In addition to emission spectra, the lifetime of the excited state (; the time it takes fluorescence to fall to 1/e of its initial value) can also be measured. The amount of emission can be measured either in terms of its quantum yield (the number of photons emitted divided by the number absorbed) or by simple intensity changes at a fixed wavelength.

Localized cellulitis can be treated with oral antibiotics and the most common offending organism is Staphylococci treatment pain during intercourse order discount azulfidine online. If the overlying erythema fails to resolve, aspiration of the partial mastectomy cavity should take place to rule out abscess formation (see Chapter 2). Frank abscesses ideally should be treated with multiple aspirations as long as improvement is documented as opposed to open treatment of the cavity, which will delay healing and potentially delay other treatments such as chemotherapy or radiation. Uncommon early complications include pneumothorax from wire localization of the breast lesion, brachial plexopathy from malpositioning on the operating room table, and Mondor disease. Mondor disease is thrombosis of the thoracoepigastric vein and presents as a palpable cord coursing vertically from the lower breast to the upper abdomen. While symptoms will resolve with time, localized heat therapy and antiinflammatory medication may facilitate quicker healing. Chapter 14 Partial Mastectomy 221 Late Complications Late complications from partial mastectomy include chronic incisional pain and breast lymphedema. Risk factors identified for chronic pain include younger age, large tumor, radiation, chemotherapy, depression, and poor coping mechanisms. Successful management has been reported with serotonin uptake inhibitors such as amitriptyline and venlafaxine. Breast lymphedema has the appearance of a diffuse cellulitis of the breast that disappears when the patient is placed in the supine position. The etiology is incompletely understood but most likely related to compromised lymphatic drainage as a result of extensive excision of breast tissue. If this condition presents in a delayed fashion, the surgeon needs to consider the possibility of local recurrence. For this delayed presentation, the next steps involve imaging and if negative, a punch biopsy to rule out breast cancer cells in cutaneous lymphatics. Treatment consists of aspiration of the seroma if large, local massage therapy after aspiration or if the cavity is already compresses, fitted compression garment and referral to occupational/physical therapy for assessment and care. For those patients who undergo radiation therapy, a rare but notable long-term complication occurring approximately 3 to 12 years after treatment is angiosarcoma. The occurrence of reddish, purplish, or bluish nodules or discolorations of the skin that are multiple on the breast or chest wall is characteristic of this tumor. Imaging that includes mammography and a search for distant disease, is the next step noting that the most common site of metastasis is pulmonary. If the mastectomy defect is large, wound coverage with flaps may need to be incorporated in the operative procedure to ensure complete resection of the disease with a wide margin (1 cm). Chemotherapy is not well established and further work is warranted in this area, thus emphasizing the important role of wide surgical excision. It is interesting to note that the majority of relapses are either self-detected or mammography screen-detected and not on clinical follow-up with the oncologist. For patients who have undergone breast conservation, the generally accepted recommendation for screening mammography of the ipsilateral breast is every 6 months for 2 years and then annually thereafter. While the data are limited on increasing survival with closer vigilance by screening mammography, the role of performing the first 6-month mammogram is to establish a baseline for following changes in the treated breast.

If utilized pain medication for dogs in labor 500 mg azulfidine buy visa, it is necessary to place ultrasound gel inside the cover for acoustic coupling between the transducer and the cover. With positioning and imaging optimized and the target lesion location in the breast reestablished, physicians the ultrasound transducer, with its long axis oriented in a direct line between themselves and the ultrasound monitor. The approach of the biopsy device toward the target lesion will be along the long axis of the transducer. The decision of the position of the entry site and the distance of the entry site from the transducer edge is dependent on the type of biopsy device and the depth of the lesion. Devices that require positioning beneath the lesion and those lesions that are deeper in the breast may require an entry site further away from the transducer edge to maintain a biopsy needle/device approach that parallels the skin and pectoral muscle. This allows better visualization of the approaching biopsy device and therefore improves accuracy and safety. Adequate local anesthesia is achieved by injecting at the proposed skin entry site and then in to the deeper breast parenchyma under direct ultrasound visualization. Injection along the pathway of the device to the target lesion and then creating a field block around the lesion is desirable. The physician can accomplish this technique by injecting anterior and posterior to the lesion and then directing the needle superior and inferior to the lesion. Anesthetizing the breast parenchyma on the far side of the lesion, where the tip of a spring-loaded device may end its excursion, adds to patient comfort. The ability to direct the placement of local anesthesia can also be valuable in moving a superficial lesion away from the skin or lifting a deep posterior lesion off the underlying pectoral muscle or augmentation implant capsule. This can be especially important when utilizing a biopsy device that requires placement under the target. The size of the skin incision made with a disposable 11-blade scalpel is a function of biopsy device but usually is between 2 and 6 mm. Once inserted through the skin incision, the physician must guide the biopsy device along the long axis of the transducer, maintaining the needle in the 1- to 1. By propping the patient with a pillow laterally and by gently pushing the far end of the transducer in to the breast, keeping the device parallel to the sole of the ultrasound transducer allowing better visualization of the advancing device tip, possibly even demonstrating a comet tail artifact, further confirms the biopsy device position for intervention. The lesion can be moved away from the skin and/or chest wall by appropriate placement of local anesthetic. Before withdrawing the device to acquire the tissue sample, the physician should perform a confirmation scan. By scanning the ultrasound transducer in a motion perpendicular to its long axis, toward the superior end of the lesion, and then back past the portion of the lesion containing the biopsy needle toward the inferior end of the lesion, it can be ensured that the needle is in the lesion. The goal is to see a portion of the lesion without a biopsy needle on either side of the scan plane containing the needle. Finally, the surgeon can obtain further confirmation by turning the transducer perpendicular to the device and imaging a cross section of the device within the lesion. Rolling the tissue off the needle trough on to a moistened telfa pad or rinsing it off in a container of saline solution is the physician preference.

Patients may be cooled externally using cooling blankets pain treatment of shingles cheap azulfidine 500 mg buy, strategically-placed ice, or using surface heat-exchange. Novel devices for external cooling continue to be developed, boasting rapid and easily induced hypothermia. It has been suggested that endovascular cooling is more rapid and easier to titrate, though no randomized data exist to support these claims. Commercially available devices are generally placed in the femoral vein, though internal cooling may be performed through any intravenous access with the use of cold saline infusion. During therapeutic hypothermia, supportive/adjunctive therapies are often required. These include vasopressors for the treatment of refractory hypotension, antiarrhythmic therapy, and tight glycemic control, to name a few. Unfortunately, shivering can often impede aggressive therapeutic hypothermia, and usually Epidemiology and Risk Factors Epidemiologic estimates suggest that most patients who present with hypertensive crises have been previously diagnosed with chronic hypertension. Commonly, these individuals have been prescribed antihypertensive therapies, but have high rates of nonadherence. In addition, patients are more likely male, African American, and have high rates of illicit drug use. Mechanisms of End-Organ Injury the pathophysiology of injury is largely speculative. Some suggest that the acute rise in blood pressure triggers a cascade of neurohormonal, vasoactive, and cellular events. The compensatory smooth muscle contraction and vasoconstriction of the larger arteries and arterioles, in an effort to preserve distal cellular activity, leads to endothelial dysfunction, inhibition of nitric oxide synthesis, and marked increases in peripheral vascular resistance. Concomitantly, mechanical stress serves as a potent stimulus for the release of inflammatory cytokines and endothelial adhesion molecules, also amplifying the renin-angiotensin-aldosterone system. These events, in aggregate, support the deleterious endothelial dysfunction, fibrinoid necrosis, vascular injury, impaired fibrinolysis, and ischemia that are causes of target-organ damage. Goals of Antihypertensive Therapy Patients presenting with hypertensive emergencies should generally be managed with immediate blood pressure control using parenteral therapy. It is important to note, however, that no consensus exists regarding the magnitude and rapidity of treatment for these acutely hypertensive patients. Some target a reduction in diastolic blood pressure of ten to fifteen percent, others argue for an absolute reduction in diastolic pressure to a value of 100 or 110 mm Hg, while still others believe that therapy should be aimed at lowering the mean arterial pressure by 20 or 25%. At the same time, the recommended speed of blood pressure reduction is arguable, though most authorities agree that blood pressure goals in acute aortic dissection should be reached within the first 5-10 minutes. In ischemic strokes, most recommend lowering blood pressure only if it exceeds 220/120 mm Hg, while intracerebral hemorrhage blood pressure targets vary considerably within the literature. One should remember, however, that several studies have consistently highlighted significant morbidity associated with rapid reductions of blood pressure in chronically hypertensive individuals.

The perioperative of aspirin withdrawal between 7 and 14 days may be associated with hypercoagulability pain treatment center connecticut buy generic azulfidine pills. Within 30 days after the vascular operation a postoperative myocardial infarction, defined by elevated troponin levels, occurred in 12%of the revascularization group and 14%of the no-revascularization group (p = 0. The authors suggested that coronary revascularization is not indicated in patients with stable coronary artery disease. Additionally, patients with left main disease have a long-term survival benefit from coronary revascularization. Poldermans and colleagues randomized 770 patients having major vascular surgery and considered as having intermediate cardiac risk, defined as the presence of one or two cardiac risk factors, to either undergo further risk stratification with stress imaging or proceed right to surgery. The conclusion of the authors was that further risk stratification in this group of patients considered at intermediate risk based on clinical history alone was unnecessary as long as perioperative beta-blockers were used, and testing only delayed necessary vascular surgery. Coronary stent placement may be a unique issue, and several studies suggest that a minimum of 30 days is required before the rate of perioperative complications is low. Several reports suggest that drug-eluting stents may represent an additional risk over a prolonged period (up to 12 months), particularly if antiplatelet agents are discontinued. The new guidelines suggest continuing aspirin therapy in all patients with a coronary stent and discontinuing clopidogrel for as short a time interval as possible for patients with bare-metal stents <30 days or drug-eluting stents <1 year. Blood Pressure and Heart Rate Management Hypertensive patients tend to have exaggerated intraoperative blood pressure fluctuations and lability. Low blood pressure should be avoided because of the shift of the autoregulation curve of cerebral perfusion in hypertensive patients. Table 14-3 lists the optimal management of blood pressure, heart rate, and contractility for those with several difference kinds of heart lesions. One should take in to account the level of training of those using the equipment and interpreting the information, and type of equipment available. Because of the potential complications, using less invasive monitoring is best when possible. General anesthesia is drug-induced amnesia, analgesia, unconsciousness, paralysis, and autonomic system control. The patient is unarousable, even to painful stimuli, and often needs ventilation either with a mask, laryngeal mask airway, or endotracheal tube. Intravenous and/ or inhalational agents are used as a balanced anesthetic technique. Inhalational agents in addition to nitrous oxide are used most commonly and include desflurane, isoflurane, and sevoflurane. They depress cardiac output in a concentration-dependent manner by decreasing systemic vascular resistance, preload, afterload, and contractility. There is no increase in myocardial ischemia or infarction with inhalational versus noninhalational techniques.

The advantages of the prone tables are the ability to biopsy the lesion in the breast from multiple approaches kearney pain treatment center discount 500 mg azulfidine with visa, where on the upright systems the approaches are somewhat limited. The patient can be positioned in either direction, allowing any approach to either breast. Presently, almost all diagnostic breast biopsies can be accomplished with a needle rather than with a knife (5). There are more patient issues reported with the "add-on" systems, particularly vasovagal reactions. These upright systems do, however, allow access to lesions close to the chest without needing exaggerated positioning that may be necessary on the prone tables. In that case, an ultrasound-guided needle biopsy should be performed instead of a stereotactic biopsy. The most common indication for a stereotactic breast biopsy is a cluster of indeterminate microcalcifications (8). Asymmetric densities and architectural distortions, frequently not imaged with breast ultrasound, may also prompt a stereotactic biopsy. The mammographic abnormality seen in only one mammographic view may possibly be biopsied stereotactically. Breast thickness in compression is the first requirement for a safe successful stereotactic biopsy. As a stereotactic program begins, a compression thickness of the breast during mammography of 28 mm should be the minimum thickness for a stereotactic biopsy. With experience, a woman with a compression thickness of as little as 20 mm may still be a candidate for a stereotactic biopsy. Patients must be able to accept the prone position without moving for the duration of the procedure, which may last from 20 minutes to 1 hour. Difficult lesions to biopsy with stereotaxis are superficial lesions, lesions close to the chest wall, and lesions in the axillary tail of the breast. However, with experience, most abnormalities can be safely biopsied with utilizing stereotaxis. Initially, these difficult lesions may challenge the learning curve of the surgeon and the radiology technologist. Chapter 4 Stereotactically Guided Breast Percutaneous Needle Biopsy 75 If pain is experienced, additional local anesthesia can be administered. She should be told that a metallic clip would be placed at the biopsy site in case a surgical excision is required as a result of the core needle pathology. This clip will remain in the breast for life unless the diagnosis requires a surgical excision at which time the clip will be removed. The patient should be made aware of the significant frequency with which ecchymosis may develop, which will dissipate with time. The patient should also be told that rarely the procedure must be cancelled for unexpected technical reasons.

If you tear it along the roll direction (its length) treatment of cancer pain guidelines 500 mg azulfidine order with mastercard, it will easily tear apart and the tear line will be smooth and even. On the other hand, tearing in the other direction would be very difficult and the tear line will appear as a random irregular corrugated line. Toilet paper is manufactured using a process that applies a force along the roll direction. Because of the applied force, the chains are aligned in the direction of the force. When you try to tear the tissue in this direction, there is no barrier to the force and the material does not resist. On the other hand, tearing the tissue requires cutting the chains in the perpendicular direction that implies resistance from the material. This is anisotropy, which means material properties are different in different directions. Pharmaceutical tablets are generally compressed in one direction, which might affect drug release or tablet properties throughout. As the free volume increases, polymer segments gain more freedom to move and this affects the temperature at which the movement occurs. For example, low- and highdensity polyethylenes are different in terms of the size of the free volume inside their structures. At a given weight, a lowdensity polymer occupies more volume as compared with its high-density counterpart. This means the polymer chain in general and the chain segments in particular can move with more ease resulting in a lower Tg value. Tg and the length of the polymer chain: Long polymer chains provide smaller free volume than their shorter counterparts. Since more free volume corresponds to lower Tg values, polymers containing short chains or having lower molecular weight possess lower Tg values. Because of its steric hindrance, higher temperature is needed to induce segmental motion in polymers containing bulky groups. For example, polystyrene and polypropylene are only different in terms of their side groups, phenyl versus methyl, respectively. The larger size of the phenyl group results in the much higher Tg value of polystyrene, 100 C as opposed to -20 C for polypropylene. On the other hand, polar side groups provide stronger intermolecular interactions that significantly affect the segmental motion of the polymer chains. Poly (vinyl chloride) is similar to polyethylene except hydrogen is replaced by one chlorine atom. Tg and polymer chain flexibility: Flexible polymer chains display higher entropy (desire to move) than rigid chains. Groups such as phenyl, amide, sulfone, and carbonyl either inside the backbone or as a side group hanging on the backbone affect the overall polymer flexibility.
