The oral mucosa is pale; there is protrusion of the upper anterior teeth, open bite, and mal occlusion (Fig. Glossodynia, loss of tongue Cyclic Neutropenia papillae, and swelling of parotid glands may occur. Cyclic neutropenia is a disorder of unknown cause characterized by a cyclic reduction in the number the diagnosis is based on specialized hematologic of circulating neutrophil leukocytes. The reduction in neutrophils occurs regularly at 3-week intervals and may last for I to 3 days. A recovery phase of 5 to 8 days follows when the Congenital Neutropenia number of neutrophils returns to normal. The disease is usually manifested in infancy or child Congenital neutropenia is also known as infantile genetic agranulocytosis. It is a rare disorder characterized by a complain of low-grade fever, malaise, headache, marked persistent decrease in circulating neu trophils, associated with severe life-threatening dysphagia, arthralgias, cervical adenitis, and skin infections.

Thrombocytopenic Purpura Thrombocytopenic purpura is characterized by a decrease in platelets in the peripheral blood. The disease may be due to a primary failure of the bone marrow to generate platelets (for example, idiopathic thrombocytopenic purpura) or it may be secondary due to a myelotoxic agent (drugs, radiation, etc. Clinically, it is characterized by a purpuric rash on the skin and mucosae and a bleeding diathesis. In the oral mucosa, petechiae and ecchymoses usually occur, especially in the palate and buccal mucosa (Fig. Episodes of bleeding from the gastrointestinal and urinary tracts and epistaxis are likewise frequent findings.

The 2-year drinking water study in rats is a well-conducted laser allergy treatment knoxville cheap cetirizine on line, peer-reviewed study that used four dose groups plus a control allergy symptoms losing voice order cheapest cetirizine. The oral 261 database includes a 2-year drinking water study in rats (Serota et al allergy treatment billing 5 mg cetirizine mastercard. The toxicity of orally-administered dichloromethane has also been investigated in an oral administration immunotoxicity study (Warbrick et al allergy shots walgreens purchase generic cetirizine pills. Several studies have also evaluated neurotoxicity associated with oral exposure to allergy news generic cetirizine 10mg online dichloromethane. The oral database lacks a two-generation reproductive study and a developmental neurotoxicity study; neurodevelopmental outcomes are relevant endpoints given that dichloromethane is capable of crossing the placental barrier and entering fetal circulation (Withey and Karpinski, 1985; Anders and Sunram, 1982) and has neurotoxic effects. Inhalation RfC the liver is the most sensitive target for noncancer toxicity in rats and mice following repeated inhalation exposure to dichloromethane. Liver lesions (specifically, hepatic vacuolation, consistent with fatty changes) in rats are the critical noncancer effect from chronic dichloromethane inhalation exposure in animals. Because the metric is a rate of metabolism rather than the concentration of putative toxic metabolites, and the clearance of these metabolites may be slower per volume tissue in the human compared with the rat, this rodent internal dose metric for noncancer effects was adjusted by dividing by a pharmacokinetic 0. This percentile was chosen because it included the most sensitive population while staying within bounds of what is 0. In addition, two 3 comparison values derived from occupational studies produced values of 1. The animal-derived candidate RfC is preferable to the human-derived candidate RfC because of the uncertainties about the characterization of the exposure, influence of time since exposure, effect sizes, and statistical power in the epidemiologic studies. The 2-year inhalation study in mice is a well-conducted, peer-reviewed study that used three concentration groups plus a control. The inhalation database includes several well-conducted chronic inhalation studies that consistently identified the liver as the most sensitive noncancer target organ in rats (Nitschke et al. However, the two-generation study is limited in its ability to fully evaluate reproductive and developmental toxicity, since exposure was not continued through the gestation and nursing periods. The results from the single dose developmental toxicity study in rats (Bornschein et al. Chronic and/or repeated exposure studies evaluating functional immunity are not available and 263 represent a data gap. The inhalation database lacks adequate developmental neurotoxicity and immunotoxicity studies at chronic low exposures. Uncertainties in RfD and RfC Values One data uncertainty identified is the potential for neurodevelopmental effects. Animal bioassays have not identified gross or microscopic effects on neural tissues from long-term exposures or single (Schwetz et al. However, behavioral changes were observed in pups born to rats exposed to high levels (4,500 ppm) of dichloromethane (Bornschein et al. Thus, uncertainty exists as to the development of neurological effects from lower gestational exposures in animals or in humans. Immunotoxicity data revealed an additional area of data uncertainty specifically with respect to inhalation exposure. The impact of this uncertainty was evaluated by re-estimating human dosimetry with the mean values for the fitted metabolic parameter reset to match those obtained by David et al. When the output was analyzed by current methods for convergence of the Markov Chain, however, not all of those measures were satisfied. Visual inspection of plots of the chains did not reveal any observable trend towards higher or lower values for any of the parameters. There was a high degree of auto-correlation in the chains, however, indicating that the statistical procedure had not yet obtained a good measure of the covariance among the parameters. Autocorrelation in the Markov Chains used to estimate the population parameters indicates that the assumed degree of independence among the parameters is overpredicted. If some combinations of parameters are less likely than other combinations (because the combination does not reflect the true correlation), and the current estimate treats those combinations as equally likely, then the level of uncertainty that is reflected in the width of the predicted confidence bounds (distribution percentiles) will be overestimated. If the chains are run longer to reach convergence, the correlation among parameters should be better identified and the resulting prediction uncertainty. Hence, these results likely lead to values of the RfC and RfD that are more sensitive than would be obtained if the chains are continued to convergence. As indicated by the sensitivity analysis, estimated risks are sensitive to possible changes in the population mean values. But given the variance in the current estimates of those means, the estimate is not expected to change by more than a factor of 3 after full convergence. The dose metric used in the models is the rate of metabolism to a putative toxic metabolite rather than the concentration (average or area under the concentration curve of the metabolite), so the model specifically fails to account for rodent-human differences in clearance or removal of the toxic metabolite. The rat model was modified, recalibrated, and utilized in a deterministic manner (Appendix C). Data were not available to perform a hierarchical Bayesian calibration in the rat, but uncertainties in the rat model predictions were assessed qualitatively. There is high confidence in the values used for volume of liver and slowly perfused tissues in the rat, as these are well studied (Brown et al. An additional uncertainty inherent in this process, however, is the lack of knowledge concerning the most relevant dose metric. This basic research question represents a data gap, and this uncertainty is not addressed quantitatively or qualitatively in the assessment. The model and resulting distributions take into account the known differences in human physiology and metabolic capability with regard to dichloromethane dosimetry. No data are available regarding toxicodynamic differences within a human population. Oral Cancer Slope Factor -3 -1 the recommended cancer oral slope factor for dichloromethane is 2 × 10 (mg/kg-day), which is based on liver tumor responses in male B6C3F1 mice exposed to dichloromethane in drinking water for 2 years (Serota et al. Significant increases in incidence of liver adenomas and carcinomas were observed in male but not female B6C3F1 mice (female data were not presented in the summary reports) (Serota et al. The study authors concluded that in the male bioassay that there was no dose-related trend, there were no significant differences comparing the individual dose groups with the combined control group, and the observed incidences were “within the normal fluctuation of this type of tumor incidence. Each of the p-values for the comparison of the 125, 185, and 250 mg/kg-day dose groups with the controls was p < 0. With respect to the issue of the comparison to historical controls, the incidence in the control groups (19%) was almost identical to the mean seen in the historical controls from this laboratory (17. However, the potential malignant characterization of the nodules was not described, and the data for hepatocellular carcinomas are much more limited. The derivation of the oral cancer slope factor is based on the male mice data because of their greater sensitivity to liver cancer compared with female mice and with male and female rats. Currently, there are no data from chronic oral cancer bioassays in mice providing support for a nonlinear dose-response relationship. There is approximately one to two orders of magnitude difference among the values based on different dose metrics, scaling factors, and populations (Table 6-1). Data for liver and lung tumors in male and female B6C3F1 mice following exposure to airborne dichloromethane were used to develop inhalation unit risks for dichloromethane (Mennear et al. This study was selected as the principal study to derive an inhalation unit risk for dichloromethane because of the completeness of the data, adequate sample size, and clear dose response. Because the metric is a rate of metabolism rather than the concentration of putative toxic metabolites, and data pertaining to the reactivity or clearance rate of the relevant metabolite(s) are lacking, the 0. Currently, there are no data from chronic inhalation cancer bioassays in mice or rats providing support for a nonlinear dose-response relationship. The distributions of inhalation unit risks for liver or lung tumors were generated by multiplying the human tumor risk factor for each tumor type and sex by the distribution of 271 3 internal doses from chronic exposure to 1 μg/m dichloromethane. A procedure to combine risks for liver and lung tumors using different dose metrics for the different tumors. There is approximately one to two orders of magnitude difference among the values based on different dose metrics, scaling factors, and populations. Uncertainties in Cancer Risk Values the database of animal bioassays identifies the liver and lung as the most sensitive target organs for dichloromethane-induced tumor development, and there is high confidence that the dose-response data for liver and lung cancer in mice represent the best available data for derivation of human cancer risks. A dose-response relationship was seen with liver cancer in mice exposed orally and with liver and lung cancer in mice exposed by inhalation. Statistically significant increases in benign mammary gland tumors were observed in one study of F344 rats exposed by inhalation to 2,000 or 4,000 ppm (Mennear et al. A gavage study in female Sprague-Dawley rats reported an increased incidence of malignant mammary tumors, mainly adenocarcinomas (8, 6, and 18% in the control, 100, and 500 mg/kg dose groups, respectively), but the increase was not statistically significant. Data were not provided to allow an analysis that accounts for differing mortality rates (Maltoni et al. The relative rarity of the tumors precludes the use of the low-dose exposure study (Nitschke et al. The available epidemiologic studies provide evidence of an association between dichloromethane and liver cancer, brain cancer, and some hematopoietic cancers. The available epidemiologic studies do not provide an adequate basis for the evaluation of the role of dichloromethane in breast cancer because there are no cohort studies with adequate statistical power and no breast cancer case-control studies with adequate exposure methodology. There is uncertainty as to whether the reactivity of dichloromethane metabolites is sufficiently high to preclude systemic distribution. Thus, alternative derivations of cancer risk values were performed under the assumption that high reactivity leads to complete clearance from the tissue in which the active metabolite is formed (scaling factor = 1. This difference reflects the lower metabolism that occurs in human versus mouse lung (relative to total): lung-specific metabolism is lower in 274 humans than mice, so the predicted risk in the lung is lower when based on lung-specific metabolism compared with whole-body metabolism. Mechanistic data support the hypothesis that reactive metabolites produced in the target tissues do not distribute significantly beyond those tissues. Uncertainties in the mouse and human model parameter values were integrated quantitatively into parameter estimation by hierarchical Bayesian methods to calibrate the models at the population level (David et al. With the subsequent deterministic application of the mouse model (using the mean value for each parameter distribution), however, the information contained in the mouse parameter uncertainties reported by Marino et al. The use of Monte Carlo sampling to define human model parameter distributions allowed for derivation of human distributions of dosimetry and cancer risk, providing for bounds on the recommended risk values. A sensitivity analysis was performed to identify model parameters most influential on the predictions of dose metrics used to estimate oral and inhalation cancer risks. In contrast, values for the three metabolic parameters were determined by computational optimization against data sets not directly measuring dichloromethane or its metabolites in the target/metabolizing tissues. Finally, while the existing model’s structure and equations have been extensively described in peer-reviewed publications, uncertainty remains concerning the model structure.

In an analysis of long-term weight gain in three large cohort studies, foods associated with greater weight gain included potato chips, sugar sweetened beverages, red meat, and processed meat, whereas fruits, vegetables, whole grains, nuts, and yogurt were associated with less weight gain . Among bever ages, sugar-sweetened beverages and fruit juices were associated with greater weight gain. Because they lack any nutritional value and are directly related to adiposity, dia betes, and cardiovascular disease, sugar-sweetened beverages are a high-priority focus area for weight control efforts in populations with substantial intakes.

Estimates of the percentage of cancers that can be attributed to excess body weight suggest that overweight and obesity are sub stantial causes of cancer in many developed countries , but the magnitude of attributable risk has varied depending on the prevalence of obesity and on other underlying assumptions. For example, esti mates for the United Kingdom for 2007 suggested that 5% and 6% Overweight and obesity the magnitude of the increase in risk of all incident cancers in men and Overweight and obesity are important varies between cancer sites.

As stated by the Center for Science in the Public Interest nutrition policy director allergy keflex symptoms buy cheap cetirizine 5mg, Margo G allergy testing reaction buy cetirizine 10 mg visa. Wootan: “Congress is giving Americans easy access to allergy injections buy cetirizine no prescription the most critical piece of nutrition information they need when eating out allergy treatment piscataway nj effective cetirizine 10 mg. While it’s a huge victory for consumers allergy forecast redwood city generic 10 mg cetirizine with visa, it’s just one of dozens of things we will need to do to reduce rates of obesity and 37 diet-related disease in this country. Seventeen present of respondents have five or more servings of fruits and/or vegetables each day, 48% had 3-4 servings, 35% had two or fewer servings. These results were skewed by income—the lowest two income brackets were twice as likely to eat two or fewer servings a day; upper income bracket was twice as likely to eat more than 3 servings a day as those making under $25,000; and by race (People of Color were almost twice as likely to eat two or fewer servings as white people). Of those who responded to the survey, 59% do not drink soda or sweet tea, 31% drink 1-2 glasses a day, and 9% drink three or more glasses a day. Qualitative: Focus Groups When discussing nutrition, many participants immediately jumped to the discussion of obesity. Overall, most participants agreed that more education regarding healthy food options would be beneficial for all members of the community. Current Initiatives and Activities the Orange County Health Department offers nutrition counseling (Medical Nutrition Therapy) to help prevent or manage certain medical conditions. Patients meet with the Registered Dietitian to develop a personalized plan to help prevent or better manage medical conditions or simply to improve the way they feel. Fees are charged on a sliding scale ($15 minimum fee) and may be covered by insurance. To qualify for the program, Elementary schools must have more than 50 percent of students participating in the free or reduced lunch program. The school received $31,194 for the year in federal funds for the program, which aims to introduce elementary school students to healthy foods by providing them with fresh produce daily. School staff hopes to foster healthy eating habits in the children and their families as well as address childhood obesity. During the 2009-10 fiscal year, Orange County Partnership for Youth Children completed the second full implementation cycle of the Growing Healthy Kids Project. Across the three garden locations in Carrboro, the Project worked with children and their families to learn healthy eating through growing their own vegetables. The Orange County Cooperative Extension program provided leadership for developing the garden sites, and provided a part-time community garden coordinator. After completing the program, parents reported a significant increase in the number of fruits and vegetables available in their home. The federal grant was open nationally to agencies both public and private, with funding going to 10 other projects throughout the United States. The Partnership was the only agency from North Carolina to receive money in this round of funding. In addition, the Orange County Health Department will create a social marketing campaign around the garden to encourage use. Through community gardening research the Orange County Health Department, in partnership with Healthy Carolinians of Orange County has established a communication and support network for community garden leaders, managers, and members in the Triangle region to learn from one another and leverage resources. These programs provide food vouchers to low-income Orange County residents, redeemable at local farmers’ markets. Started in 2009 by farmers and volunteers, program provides fresh locally grown food to people at risk for hunger, while also supporting farmers and enhancing community economic development. The Farmer Foodshare programs act as a source of community innovation to incubate self-sustaining projects that address poverty, hunger and farm loss. FarmShare works with community partners to build an inclusive, economically viable and socially just local food system in North Carolina. In its first year, the program raised over 10 tons of locally grown food for the food insecure in four counties. The campaign is collecting and distributing fresh, locally grown food for holiday meals. Bus advertisements, radio interviews, Spanish/English translated materials, flyers, events, and other activities targeted new community members to shop at the Market. The program faces the 136 2011 Orange County Community Health Assessment challenge of funding staff positions; so much of the program’s future growth will be dependent on volunteers. Eating two or more servings of fruit each day and drinking soda was significantly less likely for African Americans, while eating three or more servings of vegetables each day was significantly more likely for Asian students. Drinking soda over the past weeks was significantly more likely for high school-aged African Americans and Hispanics. Drinking two or more glasses of milk was significantly more likely for white students and significantly less likely for African 39 American and Hispanic students. Overall, the data show that Hispanics and African Americans do far worse at achieving the recommended levels of healthy food consumption; and middle school students consistently outperform high school students in most of these categories (the exception is that middle school students consume more soda per week). Access to healthy foods, such as fresh fruits and vegetables, continues to be a challenge for low income families. The Carrboro Farmers’ Market in Orange County was one of the participating markets. The pilot project will be evaluated for future expansion at the end of the 2011 season. The focus is moving away from numbers and restrictions on what to eat to more emphasis on providing healthy options and exercising personal choice. As the population continues to increase in weight, more and more young people are becoming diabetic earlier, significantly reducing their quality of life and expected lifespan. According to former Surgeon General Richard Carmona, today’s youth may be the first generation of children that will have a shorter life expectancy than their parents. Individual Level: Eating Smart Good nutrition is essential to good health and can be done by choosing more fruits and vegetables, increasing high fiber foods, choosing lean proteins and low fat dairy. A good diet can protect one from heart disease, high blood pressure, and type 2 diabetes and improve one’s total quality of life. Create joint-use agreements between school recreational facilities and parks to provide all community members with more places to be active. Encourage and facilitate walking and biking to school using the Safe Routes to School program. Policy: National Menu Labeling Ensuring that all chain restaurants are complying with the national menu labeling provision by reinforcing calorie labeling on chain restaurant menus, menu boards, drive through displays, and vending machines. All of these food options and locations should take into account cultural shopping preferences.

Broad classes of mental illness include mood disorders (depression, bipolar disorder), anxiety disorders, psychotic disorders (schizophrenia), eating disorders, personality adaptations or disorders, and addictive behaviors/substance abuse disorders. Experts at the Mayo Clinics suggest that a variety of genetic and environmental factors may contribute to the onset of illness including 1 inherited traits, biological factors, life experiences, and brain chemistry. The Mental Health Chapter in the 2007 Orange County Health Assessment also highlights stress as a significant factor. The interplay of poverty and mental illness frequently leads to a self 2 reinforcing negative spiral. If these conditions go undiagnosed or untreated, they can have serious consequences leading to disrupted daily functioning, failure in school, unemployment, disability, social isolation, family conflicts, addiction, or suicide. Many studies have shown that adults with a mental illness are much more prone to having multiple medical disorders than adults without a mental illness. For instance, individuals with schizophrenia tend to live significantly shorter lives than their non-mentally-ill peers on average; older studies estimate a 20% shorter lifespan, and newer data suggests 30-40% reduction in potential life-years, 3 with only 30-40% of that reduction attributable to suicide and injury. Furthermore, those with both 4 a mental illness and a substance abuse disorder were even more vulnerable to medical problems. The National Survey on Drug Use and Health measures symptoms and behaviors in individuals to produce an estimate of illness, its impact, and implications for policy and treatment. In an article titled “Assessing the Economic Costs of Serious Mental Illness” in the Journal of Psychiatry, Dr. Thomas Insel estimated that serious mental illness is associated with an annual loss of earnings totaling $193. These figures, while probably conservative, show the alarming burden mental illness can have on society as a whole. Addiction is a chronic, relapsing disease that follows a predictable and progressive course that may result in death if left untreated. Treatment of substance abuse disorders costs Medicaid hundreds of millions of dollars annually in medical care, suggesting that early interventions for substance abuse 8 could enhance positive treatment outcomes and save considerable amounts of money. If symptoms are recognized and treated early, many of the distressing and disabling effects of a mental illness and substance dependence may be prevented or minimized. Prevention efforts need to be focused on identifying stressors, establishing screening processes for high risk and early onset of problems, and increasing knowledge on how to access early intervention and crisis services. Secondary Data: Major Findings Mental Health In North Carolina, the rate of suicides has remained relatively constant over the period of 2000-2009 with a rate ranging from a low of 11. The suicide rate in Orange County, however, has seemed to fluctuate without any set trend between this same time period, ranging from a low of 5. One way of measuring poor mental health days is to look at presence of stress and lack of emotional support. The question asked was, “How often do you get the social and emotional support you need? However, there has been a decrease in those that have answered “Always” from a high of 10 53. However, given “perceived stress” is still a health indicator, these scores may have relevance for the individual demographics, but are most likely not useful for comparisons (saying this group or that group has more stress than another, for instance). Though there is no comprehensive dataset on alcohol use by high school students in Orange County, small-sample data is available. The 2011 SmartTrack Communities That Care Survey (N=160) th assessed 10 graders in Orange County High Schools. When asked what their use was in the past 30 days, 20% reported some beer drinking, 25% reported drinking other alcohol, and 20% reported th marijuana use. More than 25% of 10 graders reported that they had one or more beers in the past 16 three months, while 36% reported drinking other alcohol during the same time period. Another Communities That Care survey administered by Orange County Schools in spring 2008 included 957 middle school students and 333 high school students in northern Orange County who were demographically representative of the district as a whole. Sixteen percent of middle school students and 32% of high school students reported alcohol use within the past 30 days. High school 17 students reported being thirteen years old on average when they first used alcohol. Seventy-four percent of 10 graders in the 2008 Communities That Care study in Orange County schools reported that alcohol in any form was available to them with some frequency, and 40% said that it was available frequently or 18 always. Age of first use and regular use resulting from that access are important corollaries to consider, as early adopters are prone to addiction as adults at higher rates than those who begin 19 using as older adolescents or adults.
There are no quality studies evaluating opioids for treatment of shoulder dislocation (see Rotator Cuff Tendinopathies and Chronic Pain Guidelines) allergy shots burning discount 10mg cetirizine with mastercard. However allergy medicine loratadine side effects purchase cetirizine 5 mg visa, there are patients with severe pain allergy symptoms all the time buy discount cetirizine 10mg online, particularly acute dislocation patients allergy treatment vitamin c buy cheap cetirizine online, for whom the brief use of opioids gluten allergy symptoms uk cheap cetirizine online, especially to facilitate sleep, is recommended. Opioids are not invasive, have high adverse effects for a pharmaceutical (although tolerance to many can develop relatively rapidly), and are low cost when generic formulations are used. Other medications are rarely required for patients with dislocations, as the associated pain is usually acute and not subacute or chronic. However, while there is no quality evidence evaluating these medications for treating shoulder pain, they appear likely to be mildly effective for some shoulder pain patients, especially in cases involving the shoulder girdle and myofascial pain. There are no quality studies that address the use of anti-convulsant agents to treat patients with shoulder pain. By analogy, there is quality evidence that topiramate is weakly effective for treating low back pain patients, and gabapentin is unhelpful (see Low Back Complaints). Skeletal muscle relaxants are not recommended for continuous management of subacute or chronic shoulder pain, although they may be reasonable options for select acute pain exacerbations or © Copyright 2016 Reed Group, Ltd. Self applications of heat or cryotherapies might be helpful for symptom modulation. Numerous other therapies including acupuncture, ultrasound, massage, education, and exercise, etc. Taping, magnets, pulsed electromagnetic frequency and interferential have also been used to treat shoulder dislocation and instability. Recommendation: Slings for Acute Rehabilitation and Treatment of Acute Shoulder Dislocations Slings are recommended for acute rehabilitation and treatment of acute shoulder dislocations. Recommendation: Slings for Treatment of Shoulder Instability Slings are not recommended for treatment of shoulder instability. Recommendation: Self-application of Heat or Cryotherapies for Treatment of Shoulder Dislocation Self-application of heat or cryotherapies is recommended for symptom modulation for shoulder dislocation. Recommendation: Acupuncture for Treatment of Chronic Pain from Shoulder Instability Acupuncture is recommended for treatment of chronic pain from shoulder instability. Recommendation: Education and Exercise for Treatment of Shoulder Dislocation or Instability Education and exercise are recommended for treatment of shoulder dislocation and instability. Recommendation: Taping, Magnets, Pulsed Electromagnetic Frequency, or Interferential Therapy for Treatment of Shoulder Dislocation Taping, magnets, pulsed electromagnetic frequency and interferential therapy are not recommended for the treatment of shoulder dislocation. Strength of Evidence – Not Recommended, Insufficient Evidence (I) Rationale for Recommendations Slings often help manage acute pain associated with shoulder dislocations and help soft tissue healing. An external rotation brace may be used instead of a sling to treat anterior glenohumeral dislocations as most of these have an anterior inferior labral tear. The external rotation position reduces the labrum so that it can heal in a more anatomic position. Slings are not recommended for shoulder instability as the condition is chronic and slings promote debility over time. Acupuncture may be effective for treatment of chronic shoulder pain (see Rotator Cuff Tendinopathies). However, most patients with a dislocation or instability do not have chronic pain. Acupuncture might be indicated for select patients with chronic pain who do not have sufficient pain control with other interventions. Education and exercise may be useful to teach patients adaptive techniques and to facilitate continued participation in daily activities despite limitations of shoulder. Injections are occasionally needed subsequently for concomitant rotator cuff tendinopathies or among patients who have delayed recovery for unclear reasons and in whom an empiric injection for diagnostic and therapeutic purposes is performed (see Rotator Cuff Tendinopathy Injections). Recommendation: Injections for Treatment of Acute Shoulder Dislocation Injections are not recommended for treatment of acute shoulder dislocation. Recreational and occupational demands might lead one to have surgery after an initial dislocation but for most patients the results of surgery after a recurrence should be equivalent to surgery after first dislocation. Younger age has been consistently associated with increased risk of recurrence of dislocation (Hawkins 90; Hovelius 87; McLaughlin 67; Rowe 78; Robinson 08), providing some rationale for greater use of surgical treatments in younger patients with dislocations. Surgical approaches to shoulder instability include arthroscopic (Resch 97; Wiley 88; Freedman 04; Geiger 97; Steinbeck 98; Pulavarti 09; Hintermann 95; Wolf 88; Lane 93; Coughlin 92; Hawkins 89; Robinson 04; Hurley 93; Wall 95; Rook 01; Levine 05; Armstrong 04; Budoff 06; Stokes 03; Abrams 03; Abrams 07; Swenson 95; Antoniou 00; Cole 00; Angelo 03; Sandow 95,96; McIntyre 97; Rose 96; De Mulder 99; Hawkins 01; Copeland 98; Nelson 00; Long 96; Nebelung 02; Stein 02; Fealy 01; Mayfield 01; Ryu 03; Millett 03; Walch 95; Grana 93; Arciero 94; Guanche 96; Landsiedl 92; Hobby 07; Benedetto 92; Caspari 91; Morgan 87; Altchek 95; Kropf 07; Yanmis 03; Abouali 13; Friedman 14) and open procedures, most frequently Bankart (capsule and labral repairs) repairs. Recommendation: Relocation of Dislocated Shoulders Relocation is recommended after dislocation. Relocation under anesthesia is recommended if an attempted relocation without anesthesia is unsuccessful. Recommendation: Surgery for First Traumatic Anterior Shoulder Dislocation Arthroscopic or open surgery is recommended for acute, first traumatic anterior shoulder dislocation. Indications – Acute, first traumatic anterior shoulder dislocation, particularly in patients under age 27. Strength of Evidence –Recommended, Evidence (C) Rationale for Recommendations There are three high or moderate-quality studies with four reports comparing surgical treatment to non operative treatment after an acute, traumatic anterior shoulder dislocation. Another high-quality trial compared arthroscopic lavage with lavage plus Bankart repair and documented marked benefits of surgery. All trials document significantly lower rates of redislocation after repair (arthroscopic (Kirkley 99, 05; Bottoni 02) or open (Jakobsen 07)) in younger patients, from their teens to age 39, and most either under 30 and/or athletes. Trials also have shown improved shoulder function and less disability after surgery. However, quality evidence documents clear superiority of surgical management compared to non-operative treatment particularly for younger patients and thus surgery is recommended. A meta-analysis comparing transglenoid sutures with bioabsorbable tacks found a higher rate of recurrent dislocation (12. Recommendation: Surgery for Multidirectional Instability Inferior capsular shift procedure, capsular plication or superior shift of redundant inferior capsule is recommended for multidirectional and posterior instability. Strength of Evidence – Recommended, Insufficient Evidence (I) Rationale for Recommendation There are no quality studies evaluating treatment of multidirectional and posterior instability and no randomized comparative trials of available operative approaches. However, for some patients there is no other reasonable alternative for treatment, thus surgery is recommended. Recommendation: Arthroscopic Lavage for Shoulder Dislocations © Copyright 2016 Reed Group, Ltd. Strength of Evidence – No Recommendation, Insufficient Evidence (I) Rationale for Recommendations There are three moderate-quality trials with four reports all suggesting arthroscopic lavage reduces risk of subsequent dislocation. Arthroscopic lavage is invasive, has adverse effects, is costly, is less invasive than surgical repair, but does not achieve repair of damaged tissue and there is no recommendation for or against arthroscopic lavage alone.

Recommendation: Accelerated Rehabilitation for Patients after Arthroscopic Bankart Repairs Accelerated rehabilitation (compared with standard rehabilitation) is recommended for select patients after arthroscopic Bankart repairs. Frequency/Duration – Two to 3 appointments a week for 3 weeks, then twice a week for 2 weeks and once weekly to every other week for 6 to 9 additional weeks. Recommendation: Accelerated Rehabilitation for Post-operative Shoulder Instability Patients There is no recommendation for or against accelerated rehabilitation for patients after other surgical procedures for shoulder instability. Recommendation: Rehabilitation for Post-operative Shoulder Instability Patients Rehabilitation is recommended for patients undergoing surgery for shoulder instability who do not undergo an accelerated rehabilitation program (see above). Indications – Patients undergoing surgery for shoulder instability or dislocation not addressed above. Frequency/Duration – Two to 3 appointments a week for 3 weeks, then 2 a week for 2 weeks, and once a week to every other week for 6 additional weeks. Strength of Evidence – Recommended, Insufficient Evidence (I) Rationale for Recommendations There is one moderate-quality study comparing traditional with accelerated rehabilitation of patients, mean age 29 years, having undergone arthroscopic Bankart repairs for traumatic recurrent anterior instability. The dislocation rate was not increased by early rehabilitation during the study period (range 27 to 45 months). Caution should be used as excessive early range of motion in first 6 weeks will over stretch repair. Accelerated rehabilitation for other post-operative patients with shoulder instability may speed return of function, however, similar cautions exist.

Appropriate management begins with an understanding of the anatomy, etiology of pathology, and clinical correlation of pathology with symptoms and shoulder dysfunction. Labral tears are more prevalent with advancing age and thus beyond age 40 commonly represent a natural degenerative process in the shoulder not unlike meniscal pathology in the knee. The most common acute mechanism of injury reported is a compressive force on shoulder or a subluxation injury, such as from a fall on an outstretched arm (Snyder 90, 95; Resch 93; Handelberg 98; Maffet 95; Levine 00; Mileski 98; Morgan 98; Burkhart 92, 98, 00) or overhead athletic or comparable traction injuries (Trantalis 08; Burkhart 00). Labral tears occurring in an older population are most commonly associated with other largely degenerative conditions and thus might have relationships to underlying degenerative conditions and not require repair. Labral tears are often identified at surgery concurrently with other pathology such as rotator cuff tears, acromial spurring, and glenohumeral arthritis. In many of these cases, especially with advancing age, the labral tear may be irrelevant to the patient’s condition and not require specific treatment. For example, if a patient’s clinical evaluation is consistent with rotator cuff tear, an incidental labral tear does not need to be fixed (except perhaps in younger patients) and if it is fixed there is a greater chance that the patient will have post operative stiffness. Early surgery should only be considered in cases where there is evidence of suprascapular nerve compression. These relatively low sensitivity values indicate that these tests will perform poorly except in high pre-test probability circumstances.
