Four to fve days after virus inoculation the temporal bones were removed and subjected to indirect immunofuo rescence using antimeasles virus antisera blood pressure medication olmetec generic 10mg norvasc with visa. Positive immunofuorescence was observed in the infammatory cell infltrates in the cochlear ducts and the lining of the perilymphatic structure pulse pressure normal purchase 5mg norvasc with mastercard. Weight of Mechanistic Evidence Wild-type mumps virus infection has been associated with transient high-frequency-range deafness in 4 arteria gastrica dextra buy norvasc without a prescription. Permanent unilateral deafness has been reported to occur in 1 in 20 blood pressure chart throughout the day discount norvasc 2.5mg with amex,000 cases of mumps virus infection (Litman and Baum arteria pudenda externa generic 2.5mg norvasc fast delivery, 2010) arrhythmia newborn buy norvasc 2.5 mg without prescription. In addition, the eight publications described above presented clinical Copyright National Academy of Sciences. The publications presented a symptomology of fever, rash, and nystagmus consistent with direct infection of the measles or mumps viruses leading to hearing loss. The diagnosis of hearing loss after vacci nation ranged from 6 days to 4 years after vaccination. Furthermore, the demonstration of antimumps antibodies in patients with idiopathic sudden sensorineural hearing loss and detection of measles antigen in the cochlear ducts in a hamster model of measles infection suggest the involvement of measles and mumps viruses in the pathogenesis of hearing loss. The latency between vaccination and the development of the sympto mology described above ranged from hours to 12 days after administration of a vaccine containing measles, mumps, and rubella alone or in combina tion, suggesting direct viral infection as the mechanism. The committee assesses the mechanistic evidence regarding an as sociation between measles or mumps vaccine and hearing loss as low-intermediate based on knowledge about the natural infection, experimental evidence, and eight cases. The committee assesses the mechanistic evidence regarding an as sociation between rubella vaccine and hearing loss as lacking.

The varicella rash is characterized by pruritic, erythematous papules which develop into small, fuid-flled vesicles usually beginning on the scalp, face, or torso before spreading to proximal limbs and mucosal areas such as the conjunctivae (eye), oropharynx (back of the throat), and vagina (Arvin, 1996). Possible complications from varicella infection include pneumonia and secondary bacterial infections typically due to Staphylococcus aureus and streptococcus; transient hepatitis; thrombocytopenia; and various neu 239 Copyright National Academy of Sciences. Immunocompromised individuals such as those treated for cancer or with congenital defects in cellular immunity often experience more severe varicella infection and are at greater risk of fatal infection (Whitley, 2010). Prior to the development and dissemination of the varicella vaccine in 1995, varicella was a common childhood disease in the United States. Among those most often hospitalized were adults 20 years of age and older, and children 4 years and younger, respectively representing 31. Despite adults being less likely to require hospitalization due to varicella infection, from 1990 to 1994 adults were 25 times more likely to experience fatal varicella infections than children between the ages of 1 and 4 years (Meyer et al. Used within 24 hours of initial presentation, intravenous acyclovir effectively lessens illness severity and fatality in immunocompromised indi viduals (Nyerges et al. Instead, they recommended that the oral treatment be reserved for otherwise healthy individuals at increased risk for moderate to severe varicella such as individuals 13 years or older and persons with chronic skin or pulmonary disorders (Hall et al. The frst live attenuated varicella vaccine was developed and tested in Japan by Takahashi and colleagues in the 1970s. In 1979, the National Institute of Allergy and Infectious Diseases sponsored the Varicella Vaccine Collaborative Study that looked at the effectiveness of the vaccine on children whose leukemia was in remission. The Collabora tive Study showed seroconversion in 88 percent of leukemic children after Copyright National Academy of Sciences. Two sections deal with initial adverse events (1) limited to the skin or (2) involving dis semination to other organs. The committee arbitrarily placed all cases reporting herpes zoster in the viral reactivation sections even when these rashes appeared early after administration of the vaccine. Reports in which there were a few vesicles at the site of the injection were not included. The cases that were used to defnitively show the association were those in which (i) the patient received the varicella vaccine currently in use in the United States or one similar, (ii) the rash extended to dermatomes beyond that of the initial injection, and (iii) vaccine virus was demonstrated in skin lesions. Thirty-three publications either did not provide evidence beyond temporal ity or demonstrated wild-type varicella virus in the vesicles (Alpay et al. Described below are 21 publications reporting clinical, diagnostic, or experimental evidence that contributed to the weight of mechanistic evi dence. The studies are grouped to indicate the certainty that the vaccine was suffciently similar to that used currently in the United States and that there was primary dermal dissemination of vaccine virus. Studies from prior to general use of the vaccine report many rashes and other adverse events associated with wild-type varicella virus because of the high prevalence of wild-type disease. New lesions continued to appear for more than 14 days after the appearance of the initial lesions. Laboratory tests showed pancytopenia re fecting macrocytic-normochromic-hyporegenerative anemia. Kraft and Shaw (2006) described a 36-year-old man presenting with pruritic lesions on the face, limbs, and trunk 24 days after receiving a varicella vaccine and 2 years after undergoing a heart transplant. Other Cases There were fve publications describing reports submitted to passive surveillance systems regarding rash associated with vaccine virus without other organ involvement in the frst 42 days after vaccination. The limita tion of these publications is that the distribution of the rash is not reported, so the committee cannot conclude that the rash disseminated beyond the site of the initial injection. Due to the use of the same databases, it is likely that many of the cases overlap in the four publications. The remaining specimens either tested negative for varicella virus or were inadequate for testing. The remaining specimens were negative for varicella virus, positive for varicella virus but untypable, or inadequate samples.

Not recommended for continual use pulse pressure range elderly buy cheap norvasc, rather periods without use have been recommended prehypertension exercise trusted 2.5 mg norvasc. Recommendation: Yoga for Chronic Hand Osteoarthrosis or Acute Flares of Osteoarthrosis Yoga is recommended for treatment of chronic hand osteoarthrosis or acute flares of osteoarthrosis blood pressure medication yellow pill order norvasc online now. As yoga is not invasive blood pressure eye pain purchase norvasc 10 mg otc, has few adverse effects blood pressure normal buy generic norvasc from india, and is low cost prehypertension bp range buy norvasc 5 mg on line, it is recommended for select, motivated patients. There are more than 30 quality studies reviewed in the Hip and Groin Disorders Guideline. This quality literature mostly addresses hip or knee osteoarthrosis or low back pain. Of the 5 quality, double-blinded studies that used x-rays for evaluation of glucosamine/chondroitin, three have documented delayed progression of joint space narrowing. There are 3 low-quality studies of chondroitin sulfate for treatment of hand arthrosis with one suggesting delay of hand x-ray changes. However, glucosamine and chondroitin have problems with lack of standardization of doses. Consequently, although these agents are not invasive, have low adverse effects profiles, and may be costly over time, there is no recommendation for or against these agents. Of the 9 articles considered for inclusion, 9 randomized trials and 0 systematic studies met the inclusion criteria. Of the 1 articles considered for inclusion, 1 randomized trials and 0 systematic studies met the inclusion criteria. These injections are generally performed without fluoroscopic or ultrasound guidance in the distal upper extremity. Recommendation: Intraarticular Glucocorticosteroid Injection for Subacute or Chronic Hand Osteoarthrosis Intraarticular glucocorticosteroid injections are recommended for the treatment of subacute or chronic hand osteoarthrosis. Its usual purpose is to gain sufficient relief to either resume medical management or to delay operative intervention. There are no head-to-head comparisons in quality studies of different medications to ascertain optimum medication(s). If there has not been a response to a first injection, there is generally less indication for a second. If the physician believes the medication was not well placed and/or if the underlying condition is so severe that one steroid bolus could not be expected to adequately treat the condition, a second injection may be indicated. If placement is thought to be difficult, ultrasound or fluoroscopic guidance may be particularly indicated for a second injection. In patients who respond with a pharmacologically appropriate several weeks of temporary partial relief of pain, but who then have worsening pain and function and who are not (yet) interested in surgical intervention, a repeat injection is an option. There are not believed to be benefits beyond approximately 3 injections in a year. Patients requesting a 4th injection should have reassessment of non-operative management measures and be counseled for possible surgical intervention. Recommendation: Intraarticular Hyaluronate Injection for Subacute or Chronic Hand Osteoarthrosis Intraarticular hyaluronate injections are recommended for the treatment of subacute or chronic hand osteoarthrosis. Its usual purpose is to gain sufficient relief either to resume medical management or to delay operative intervention. Optimal glucocorticoid doses and preferable adjuvant anesthetic agents are unclear. These injections are invasive, have low adverse effects, and are moderately costly. There are a few quality studies of hyaluronate injections for treatment of hand osteoarthrosis. Duration of improvement is uncertain, although one trial suggested pain relief as far as 26 weeks. In select cases where other treatments have failed, these injections are recommended. Of the 9 articles considered for inclusion, 6 randomized trials and 1 systematic studies met the inclusion criteria. The hands with thumb base vs pinch, tripod pinch and key intra-articular hylan was were randomized. The Hylan group strength at 24 weeks also showed significant when compared to improvement with regards placebo. The difference sodium hyaluronate Follow-up for 12 was not significant at 12 injection in reducing pain months. Sodium hyaluronate improved significantly for improvement intraarticular injection steroid group. Of the 8 articles considered for inclusion, 8 randomized trials and 2 systematic studies met the inclusion criteria. Imaging effects are not used; achieved more slowly, the Follow Up at results indicate baseline, 3, 14, a superior long and 26 weeks. All received steroid superior at Weeks injections for difference but and Genzyme 2 injections, 1 2 and 4 to baseline and most of the stats for age are Corporation. Surgery Various surgical procedures are utilized to treat patients with hand osteoarthrosis. Recommendation: Reconstructive Surgery for Select Patients with Trapeziometacarpal Arthrosis Reconstructive surgery is recommended for treatment of select patients with trapeziometacarpal arthrosis. Recommendation: Fusion for Select Patients with Hand Osteoarthrosis Fusion is recommended for treatment of select patients with hand osteoarthrosis. Regardless, ligament reconstruction and tendon interposition procedures do not appear to be superior to the simpler trapeziectomy,(1534, 1535, 1541, 1549, 1550, 1555, 1556) and some studies suggest longer recovery and higher complication rates with the more extensive procedures. Thus, the ligament reconstruction with tendon interposition procedure is generally not recommended. One moderate-quality study has concluded that earlier mobilization is superior to delayed mobilization after surgery. Thus patients should be appropriately counseled as they may decide that the fulfillment from performing physical labor outweighs the discomfort. However, joint fusion is generally helpful for patients with significantly symptomatic osteoarthrosis who fail to achieve sufficient relief from other treatments. Of the 5 articles considered for inclusion, 5 randomized trials and 2 systematic studies met the inclusion criteria. Author/Year Score Sample Size Comparison Group Results Conclusion Comments Study Type (0-11) Trapeziectomy vs. There was no orthotic or extension and flexion) and thumb significant difference Semi-rigid interphalangeal joint (extension between the two groups orthotic groups. Patient comfort, cost and availability may determine choice between orthoses in clinical practice. In Results suggest no mention of trapeziometa interposition using 50% of flexor or 1 year (p = 0. Post-operative splinting was previously widely used as evidenced in the older quality literature. Recommendation: Soft Bandages During Post-operative Rehabilitation Soft bandages are recommended during post-operative rehabilitation. Recommendation: Splints During Post-operative Rehabilitation Splints are recommended during post-operative rehabilitation for select patients. Three low-quality studies all suggest that splints are not effective;(784, 1559, 1560) however, there is no quality data and some splints appear indicated for select patients. Thus, there are limited indications for splints in patients with select diagnoses generally involving more extensive surgical procedures or other needs to utilized splints for protective purposes. Of the 18968 articles considered for inclusion, 11 randomized trials and 1 systematic studies met the inclusion criteria.

Therapy Control group: hand or activity performance in improved hand Association, exercises only (n = 29). We recommend a home physiotherapy programme in which the wrist and fingers are exercised separately to avoid simultaneous finger and wrist flexion, which is the position most prone to cause bowstringing. Recommendation: Acetaminophen During Post-operative Rehabilitation Acetaminophen is recommended to control pain during post-operative rehabilitation. Of the 13542 articles considered for inclusion, 10 randomized trials and 0 systematic studies met the inclusion criteria. No mention of elective hand regional presurgery method of giving it sponsorship or surgery.

Recommendation: Cryotherapy During Post-operative Rehabilitation Cryotherapy is recommended for post-operative rehabilitation for carpal tunnel release patients. Recommendation: Cooling Blanket During Post-operative Rehabilitation A cooling blanket is recommended during post-operative rehabilitation. The evidence is in favor of a cooling blanket versus ice therapy and therefore, a cooling blanket is recommended during post-operative rehabilitation. Recommendation: Activity During Post-operative Rehabilitation for Patients with Functional Deficits It is recommended that post-operative patients or those with functional deficits stay as active as possible and use the hand as much as possible post-operatively or post-injury. Recommendation: Exercise During Post-operative Rehabilitation for Patients with Functional Deficits It is recommended that post-operative patients or those with functional deficits perform graded, increased exercises post-operatively or post-injury.

Burr Cells (Echinocytes) Burr cells (echinocytes) are red cells with approximately 10 to 30 rounded spicules evenly placed over the surface of the red cells (see Fig. They may be observed as an artifact, usually as a result of specimen contamination, in which case they will appear in large numbers and will present with evenly dispersed smooth projections and may be referred to as cre nated. The terms crenated cell and echinocyte may be used interchangeably by some reviewers and therefore are not reported. They may be seen in uremia, heart disease, cancer of the stomach, bleeding peptic ulcer, immediately following an injection of heparin, and in a number of patients with untreated hypothy roidism. In general, they may occur in situations that cause a change in tonicity of the intravascular uid.

The most prominent pathologies in which acantho numbers is the rare condition abetalipoproteinemia. The extent to which a portion of the red cells form tails is variable, and these cells may be normal, reduced, or increased in size. The exact physiologic mechanism is unknown, yet teardrop for mation from inclusion-containing red cells is well docu mented. As cells containing large inclusions attempt to pass through the microcirculation, the portion of the cells contain ing the inclusion cannot pass through and consequently gets pinched, leaving a tailed end. For some reason, the red cell is unable to maintain the discocyte shape once this has occurred. Teardrop cells are seen most prominently in idiopathic myelobrosis with myeloid metaplasia. This type of morpho logical nding can also be seen in patients with the thalassemia Figure 5-25 Note the acanthocytes on this peripheral smear. They may also be seen in megaloblastic processes as other hemolytic anemias, and in megaloblastic anemias.

Chapter 5 Evaluation of Cell Morphology and Introduction to Platelet and White Blood Cell Morphology 109 that Romanowsky stains visualize Pappenheimer bodies by staining the protein matrix of the granule, whereas Prussian blue stain is responsible for staining the iron portion of the granule. Once the presence of siderotic granules has been con rmed by iron stains, the cells in which they are found are termed siderocytes. Siderocytes containing a nucleus are described as sideroblasts and are commonly seen in siderob lastic anemias. Sideroblasts exhibiting numerous siderotic granules found within the mitochondria forming a ring around at least one-third of the nucleus, are labeled as pathologic ringed sideroblasts. Siderocytes are seen in any condition in which there is iron overloading such as hemochromatosis or hemosiderosis.

They can be formed for visualization in vitro by incubation with phenylhy Pappenheimer Bodies and Siderotic drazine (a strong oxidizing agent). On initial exposure to Granules phenylhydrazine, small crystalline bodies appear, coalesce, and migrate to an area beneath the cell membrane. This pro Pappenheimer bodies (siderotic granules) are small, irregular cedure is used before staining with crystal violet or brilliant magenta inclusions seen along the periphery of red cells. They cresyl blue where the presence of Heinz bodies may be seen usually appear in clusters, as if they have been gently placed on on the peripheral smear. Even though Pappenheimers and siderotic granules are the same inclusion, they are designated differently depending on the stain used. The inclusions are termed Pappenheimer Cabot Rings bodies when seen in a Wright-stained smear (Fig. This structure may represent a part of Figure 5-31 Heinz body prep; note the appearance of Heinz Figure 5-30 Pappenheimer bodies (Wright stain). HbC disease is a mild chronic hemolytic anemia in which the patient is homozygous for the abnormal hemoglobin C. The crystal forms in a hexagonal shape with blunt ends, leaving the remainder of the cell with the appearance of being empty. The species include Plasmodium vivax, Plasmodium malaria, Plasmodium falciparum, and Plasmodium ovale and are transmitted by the Anopheles mosquito. The primary concern is the recognition of the abnormality as a parasite and that it is not confused with normal morphology such as platelets superim posed over red cells. It is transmitted by tick bites and may appear as ring Figure 5-33 Note the hexagonal shaped crystal inclusions in a forms resembling some forms of malaria. Patient symptoms and travel history are also useful in differentiating the two organisms (Fig. In rare instances, one may see megakaryocytic fragments in the peripheral circulation. Gross variation in platelet morphology may be seen appearance on a peripheral blood smear is conrmation of infec in inltrative disease of the bone marrow. Regardless of the reason for the appearance of the immature cells, the reviewer should be able to identify the cells accurately. Neu trophils tend to exhibit a wider variety of morphologic changes than the other cell types with these changes originat ing in the cytoplasm in response to various pathologic processes. The specic alteration may involve the appearance or lack of cytoplasmic inclusions. In addition to the elevated platelet count, and Dohle bodies are generally considered nonspecic reac morphological changes may also occur postsplenectomy. They areas that are dispersed randomly throughout the cytoplasm must also distinguish between normal granularity and the pres of neutrophils in patients with overwhelming infections. Dohle bodies may be seen in peripheral blood the presence of immature cells is a signicant nding, smears of patients with severe infections, in patients with severe with the greater the immaturity, typically, the more severe the burns, in pregnant women, and in patients receiving chemotoxic diagnosis. In addition to these morphological changes, severe bacter ial infections are also commonly associated with a moderate leukocytosis and a shift to the left in granulocytes. Mild infec tions are characterized by a slight leukocytosis, with or without the shift to the left. These particular cell populations may often be observed during an infection or inammatory process. The degree of leukocytosis or neutrophilia is useful in discriminating among bacterial, viral, or fungal conditions. Acute infections, chronic infections such as tuber Microcytosis 1+ culosis and chronic osteomyelitis, as well as severe metabolic Schistocytes 2+ inammatory and neoplastic processes have all been associ Sickled cells 1+ ated with leukemoid reactions.

The disease is not evident at birth and does not manifest this transient condition may be associated with such stimuli itself until the gamma chains of the newborn are replaced by as exercise, intense emotional stress, anesthesia, or the s-chains after 3 to 6 months of life. Patients in sickle cell crisis pre sent with acute pain, fatigue, and possibly jaundice. All three of these symptoms were present in our case study, as was evidence of some form of anemic process. Case Study 1 Chronic manifestations of sickle cell disease usually appear after mid-childhood. On examination there is a denite yellow patible to the results from the analyzer These abnormalities are typically seen in patients Morphology results correlate with the values from the in crisis as was this child. The sickledex is a screening test performed on whole blood and is positive in both sickle cell disease and sickle cell trait. The confirmatory test is the hemoglobin electrophoresis, which will differentiate abnormal hemoglobin traits from abnormal hemoglo bin disease. In cases of sickle cell crisis, in which the nonfunctional sickle cells are be ing destroyed, a properly functioning marrow should accelerate the hematopoietic process. The 13% reticu locytes count is indicative of a proper response by the bone marrow to the hemolytic process the patient was experiencing.

In addition to phagocytosis, neutrophils also release cytokines, which amplify the response. Also note that an increase in the percentage of neutrophils by necessity decreases the percentage of lymphocytes.

This human potential remains unused progress goes hand in hand with rising incomes, producing the highest standards of living in hu Human development has been uneven among man history. All are important facets of human ratio was only 21 per 100,000 live births in development. Organisation for Economic Co-operation and Between 1990 and 2015 income poverty in Development countries, compared with 183 in developing country regions fell by more than South Asia (see table 5 in Statistical annex). The number of extreme poor people Globally women earn 24 percent less than worldwide fell from 1.

Whether peo Asia and increasingly by Sub-Saharan Africa, ple have a job is important, as are other issues. Are there prospects care gap between care needs and care providers for advancement Are there equal estimates indicate that there is a global shortage opportunities for women and men Greater longevity, ageing, the whether it facilitates participation and inter youth bulge and dependency ratios will all have action. Work strengthens its expected to live in urban areas, stressing the link with human development when it goes coping capacities of cities. At the end of 2014, 60 million people inequality reduction, social cohesion, culture had been displaced worldwide. Violence weaker when there is discrimination and vio against women is one of the most brutal threats lence at work. But discrimination also demics, by emerging health risks, by economic occurs along lines of race, ethnicity, disability Overview | 5 and sexual orientation.

Networks of traffickers take money abusive and exploitative conditions that violate from desperate migrants who try to cross seas their basic human rights and destroy their dig and land illegally into other countries. In 2014 nity, such as child labourers, forced labourers some 3,500 people, maybe many more, lost and trafcked workers (fgure 3). And millions their lives in the Mediterranean Sea when traf of domestic, migrant, sex and hazardous-indus fcking boats heading towards Europe, mainly try workers face various risks. But abuse is common in paid domestic work, particularly for female migrant workers.

In 2015, 81 percent of households technological revolution in developed countries had Internet access, around 168 million are fast changing how we compared with only 34 percent in developing child labourers and work and what we do country regions and 7 percent in the least de 21 million people veloped countries. Driving the together in global networks through out transformation of work are globalization and sourcing and global value chains. Companies technological revolutions, particularly the relocate or subcontract (or a bit of both) some digital revolution. Globalization has fostered functions or noncore activities to other coun global interdependence, with major impacts tries where costs are lower. The digital components of these fows intermediate goods and services organized in have also been increasing. United States it took more than 50 years be In recent years knowledge has become fore half the population had a telephone. By the value of fnished goods comes increasingly the end of 2015 the planet will have more than from embodied knowledge. In 2012 trade 7 billion mobile subscriptions and more than in knowledge-intensive goods, services and 3 billion Internet users. It has also revolutionized creative work and empowered small producers and artisans. Globalizing work has Technological advances have not only generated gains for some transformed work; they are also engines and losses for others for new forms of creativity and innovation. Collaborative teams and visionaries have With outsourcing, assembly jobs in developed turned ideas into tangible goods and services. The impact 2012 their share in all new patents more than on job creation in large developing countries doubled, from more than 25 percent to nearly such as China and Mexico, as well as smaller 55 percent. Services are revolutions ity of knowledge work and enable millions to also growing in the Russian Federation, Latin use intelligent digital assistants. But outsourc retrain, relocate and renegotiate working con ing to developing countries has not beneftted ditions. This group has come of age Estimates vary, and the long-term impacts at a time when digital technologies and ad are less clear than the short-term efects, but vanced information and communication tech job losses are greater in manufacturing than nologies penetrate all areas of life. Short-term job losses due to ofshor also become adults at a time when fexibility, ing have been found to range from 0 in some adaptability and unconventional work are in countries to almost 55 percent of all job losses creasingly common. Many millennials are looking for work that Today, jobs that involve administrative sup goes beyond creating profts, hoping to solve port, business and fnancial operations, and environmental and social problems as part of computer and mathematical tasks are most their livelihoods. Many jobs in increases in productivity are shared between this estimate are in medium and high-skilled workers and capital. Multinational corporations training and new skills for a more competitive increasingly rely on a disenfranchised work environment. To ease the adjustment, pro force, using a mix of fixed-term employees, grammes are needed to help people fnd new temporary workers, independent contractors, work, enhance their skills and maintain access project-based workers and outsourced workers to a basic income. Training can also enhance to provide production fexibility and manage the abilities of workers in developing countries costs. But such integration does not say much the types of work that people do and the about the quality of work and whether workers ways they do it are being transformed by new have expanded their human capabilities. This change is not new, but it is are concerns about levels of labour protection reshaping the link between work and human and opportunities for skills upgrading. The footloose nature of global The spread and penetration of digital tech value chains can generate less job security and nologies are changing the world of work every put even more pressure on governments and where, but the efects vary across countries. Still, countries become central becoming locked into low value-added nodes will continue to have divergent production and to production of global value chains that limit work oppor employment structures and diferent uses for tunities, skill development and technology digital technologies, largely refecting the rela exposure. In Ethiopia farmers use mobile phones to skilled workers while increasing demand for check cofee prices. By defnition, such change use wireless technology to distribute scarce favours people with higher human capital, po irrigated water for wheat cultivation. The biggest losers will thus be workers been a worse time Internet and mobile phone access empowers with less specialized, routine-work skills (fg to be a worker with people to harness their creativity and inge ure 5). Much more is possible, particularly if Many cognitively complex jobs are beyond only ordinary skills inequalities in access between men and wom the abilities even of people with reasonable and abilities en and rural and urban areas are addressed. Some industries could thus face If Internet access in developing countries skill shortages, so companies willing to pay high were the same as in developed countries, salaries for the best talent will look to the global an estimated $2.
