Because most birds entering the pet trade come from domestic sources, it is to the advan- tage of avian practitioners to become knowledgeable in avicultural and pediatric medicine. Precocial birds such as pheas- ants, ostriches and waterfowl are covered with down and are able to see, walk and feed themselves at hatching. Altricial species such as psittacine birds, song birds and pigeons are helpless at hatch. Most altricial birds are born naked with their eyes closed and depend totally on their parents for food and warmth. Because they are helpless, the conditions under which they are maintained, the diet they are fed and the amount of parental care they receive all have a profound influence on their health.

The annual review examines and summarizes any needs for improvement in program quality 160mg malegra fxt plus for sale ayurvedic treatment erectile dysfunction kerala, resident performance generic malegra fxt plus 160mg on-line coke causes erectile dysfunction, faculty development buy cheap malegra fxt plus on line erectile dysfunction boyfriend, or graduate performance discount 160mg malegra fxt plus otc erectile dysfunction doctor boston. Residents being evaluated will receive an email notification when an evaluation has been completed. Residents are also evaluated by technologists, pathology assistants and autopsy assistants. In addition to rotation evaluations, information from other sources will be considered. These include attendance records for required academic sessions, results of written examinations, and informal reports. Residents are reviewed as to performance by the Residency Director at least twice yearly. Please refer to the Housestaff Policies and Procedure Manual for details of the recommended institutional guidelines pertaining to progress and promotions. A poor grade or unsatisfactory rotation evaluation will result in formal counseling, which may include development of a remediation plan, repetition of the rotation or probation. Very specific guidelines from the School of Medicine govern remediation, probation, and due process/grievance procedures pertaining to any such actions. Please refer to the appropriate section in the Housestaff Policy and Procedure Manual for details. Whenever the Residency Director is informed of significant concern regarding a resident’s performance, the resident involved will be contacted and given the opportunity to provide a response. The resident may provide this response by any or all of the following: in the form of a written document, through verbal communication with the residency director, or by personal appearance before the departmental Residency Review Committee. Questions of capricious, arbitrary, punitive or retaliatory actions or interpretations of the policies governing graduate medical education on the part of any faculty member or officer of the Pathology Residency Program are subject to the grievance process. Complaints of illegal discrimination, including failure to provide reasonable accommodations and sexual harassment, are processed in accordance with the Medical Center policies and procedures that are administered through the Equal Opportunity Office. Should a house officer in the Department of Pathology have a grievance or be dissatisfied with any aspect of the program, he/she is encouraged to initially discuss the issue with his/her attending or the Chief Residents. If this is felt by the resident to be inappropriate or the issue is not satisfactorily resolved, timely discussion with the Program Director is highly recommended. Documentation of the issues and a statement of dissatisfaction by the aggrieved resident may be helpful, and is also encouraged, particularly when making an appeal to the Department’s Resident Education Committee. In general, the resident will first discuss any grievance with the Chief Residents. If this fails to provide adequate closure to the grievance, then he/she is directed to speak with one of the Program Director. Issues can best be resolved at this stage and every effort should be made to achieve a mutually agreeable solution. If the grievance is not resolved to the satisfaction of the resident after discussion with the Program Director, the resident has the option to present the grievance, in writing, to the Office of Graduate Medical Education. In situations where the grievance relates to the Chair or Program Director, or where the resident believes that a fair resolution cannot be attained by presenting the grievance to those individuals, he/she may present the grievance in writing directly to the Office of Graduate Medical Education. The Associate Dean for Graduate Medical Education will meet with the resident, the Program Director, the Chair and one or more of the program’s Chief Residents to determine the cause and validity of the complaint and to determine the means of redress. Should the meeting with the Associate Dean fail to resolve the grievance to the satisfaction of the resident, the resident may request that he/she be heard by the Executive Dean. Any action(s) taken in good faith by the Executive Dean addressing the grievance will be final. An appropriate ratio of education to service is ensured by providing a blend of supervised patient care responsibilities, clinical teaching, and didactic education. The Program provides an educational and working environment in which residents may address concerns in a confidential and protected manner. Residents are integrated and actively participate in interdisciplinary clinical quality improvement and patient safety programs. Appropriate educational resources are provided including medical information access, faculty supervision, and a wide variety and volume of both anatomic and clinical pathology cases. Graded and progressive clinical responsibility within the supportive educational environment assures resident development of sufficient competence to enter practice without direct supervision upon completion of the program. Therefore, the use of protective equipment to prevent parenteral, mucous membrane and non-intact skin exposures to a healthcare provider is recommended; iii. Such opportunities include, but are not limited to, confidential discussion with the chief residents, program director, program chair, core program director, and/or core program chair. Other intradepartmental avenues to confidentially discuss any resident concern or issue occur during the Annual Program Evaluations completed by each resident and/or through discussion with the resident representative during the required Annual Program Review (Annual Program Outcomes Assessment and Action Plan Report); ii. E*Value “On-The-Fly” praise and concern comments can be sent through E*Value directly and confidentially to those program directors that offer this service. All procedures performed in autopsy, surgical pathology and clinical laboratory medicine are performed under either direct or indirect supervision of an attending faculty member. Resident responsibilities and progression of responsibility is described in each rotation description. More Pathology Resident Manual Page 29 advanced residents are given increased responsibility which will include more time on each procedure or task being indirectly supervised (immediate availability) by the faculty member. Supervision of Residents • In the clinical learning environment, each patient must have an identifiable, appropriately- credentialed and privileged attending physician (or licensed independent practitioner as approved by each Review Committee) who is ultimately responsible for that patient’s care. Pathology Resident Manual Page 30 • Indirect Supervision B (with direct supervision available): o This means the supervising physician is not physically present within the hospital or other site of patient care, but is immediately available by means of telephonic and/or electronic modalities, and is available to provide Direct Supervision. The ultimate responsibility for a patient’s care, however, lies with the attending physician, and cannot belong to a pathology assistant. This must include the opportunity to work as a member of effective inter- professional teams that are appropriate to the delivery of care in the specialty. Intermediate residents and residents in the final years of education may stay on duty or return to the hospital to perform intra-operative consultations, apheresis, emergent autopsies (e. Likewise, on call residents and faculty are posted online and distributed to all residents and faculty each month. Informing patient of resident role: When residents have direct contact with patients (e. To minimize patient care transition, residents are assigned to month long rotations in which they manage individual cases from beginning to end. In certain circumstances, such as end of the month transition in surgical pathology, or when residents are contacted during at-home on call, the following Handoff policies must be followed. For on call residents, if the resident is called in during the night: • Write the details regarding the call (e. For on call residents, if the resident receives a phone call not requiring coming in: • Send an email (prior to 8:30 am) with the call details to the pertinent resident and attending, both chief residents, and Brooke. The faculty member will advise the chief resident if another resident needs to be immediately sought to help with the clinical tasks or if such duties may be delayed until additional resident help is available. All such incidents need to be recorded by the chief resident and reported to the Program Director. The circumstances leading to the event will be investigated by the Program Director. Need for intervention with the resident or for process changes with the clinical rotation will be evaluated. Please refer to the online Graduate Medical Education Policy and Procedure Manual @ http://www. Pathology Resident Manual Page 34 Duty Hour Restrictions Duty hours are defined as all clinical and academic activities related to the residency program; i. Duty hours do not include reading and preparation time spent away from the duty site. Duty hours must be limited to 80 hours per week, averaged over a four week period, inclusive of all in- house call activities and all moonlighting. Residents must be provided with 1 day in 7 free from all educational and clinical responsibilities, averaged over a 4-week period, inclusive of call. One day is defined as 1 continuous 24-hour period free from all clinical, educational, and administrative duties. At-home call (or pager call): The frequency of at-home call is not subject to the 8 hours between duty periods rule. However at-home call must not be so frequent as to preclude rest and reasonable personal time for each resident. In cases where residents return to work in less than 8 hours, the resident will be asked to verify the reason for the extended duty hours by filling out the “Extended Duty Hours” form. The resident is expected to be rested and alert during duty hours, and the resident and resident’s attending medical staff are collectively responsible for determining whether the resident is able to safely and effectively perform his/her duties. If a scheduled duty assignment is inconsistent with the Resident Agreement or the Institutional Duty Hours and Call Policies, the involved resident shall bring that inconsistency first to the attention of the Program Director for reconciliation or correction. If the Program Director does not reconcile or correct the inconsistency, it shall be the obligation of the resident to notify the Department Chair or Associate Dean for Graduate Medical Education, who shall take the necessary steps to reconcile or correct the raised inconsistency. On-Call and Resident Time Record Reporting At-home call (or pager call) is defined as a call taken from outside the assigned institution. Pathology Resident Manual Page 35 The frequency of at-home call is not subject to the every-third night or “24+4” limitations. At-home call, however, must not be so frequent as to preclude rest and reasonable personal time for each resident. Residents taking at-home call must be provided with 1 day in 7 completely free from all educational and clinical responsibilities, averaged over a 4-week period.

purchase malegra fxt plus toronto

In fact order malegra fxt plus 160mg with amex erectile dysfunction pills from china, it would be worthwhile to read the chapter “Breast Cancer (Prevention)” to gain an even greater appreciation of how diet can affect hormone-sensitive tissues like the breast and prostate buy malegra fxt plus 160mg mastercard latest erectile dysfunction medications. One of the interesting dietary associations in breast cancer is the high risk that comes with eating well-done or charbroiled meat; frequent consumption of well-done meat order malegra fxt plus on line erectile dysfunction treatment operation, for example cheap malegra fxt plus online amex erectile dysfunction drugs used, was associated with a nearly 500% increase in breast cancer. Higher consumption of hamburgers, processed meats, grilled meats, and well-done meat was associated with an approximately 50 to 80% increase in aggressive forms of prostate cancer. In a study conducted in Canada, researchers found a twofold increased risk of prostate cancer associated with an increased intake of milk. Interestingly, it was the only dairy product associated with an increased risk for prostate cancer. It is also important to point out that the Mediterranean diet has been shown to help prevent prostate cancer. That would be expected given that it is high in vegetables, legumes, dried and fresh fruits, and fish; olive oil is its main fat source; it is low in animal fats, processed red meat, milk and dairy products; and it includes regular but low alcohol intake (wine with meals). The high intake of soy may be one of the key protective factors accounting for the low rate of prostate cancer in Japan and China compared with other parts of the world: blood and urine concentrations of soy isoflavones (an indicator of intake) were found to be 7 to 10 times higher in Japanese men consuming a traditional Japanese diet compared with Finnish men consuming a typical Western diet. Information on the isoflavone content of common soy foods can be found on page 788. Just as in breast cancer again, the benefits of these long-chain omega-3 fatty acids are magnified when the level of animal fat (saturated fat, and arachidonic acid in particular) is also reduced. A high ratio of dietary omega-6 to omega-3 fatty acids is major risk factor for prostate cancer. Unfortunately, no one has actually looked at the effect of flaxseed oil in prostate cancer. At this time it appears that men in general may be better off avoiding flaxseed oil supplements and focusing on ground flaxseed (for the lignans) and fish (for the omega-3 fatty acids). Flaxseed Ground flaxseed appears to be quite helpful not only in preventing prostate cancer but also in men with existing prostate cancer. In addition to its phytoestrogenic effect, flaxseed lignans also bind to male hormone receptors and promote the elimination of testosterone. In a study of men with prostate cancer, a low-fat diet (with fat providing 20% or less of total calories) supplemented with 30 g ground flaxseed (roughly 2 tbsp) reduced serum testosterone by 15%, slowed the growth rate of cancer cells, and increased the death rate of cancer cells after only 34 days. Although genetics could play a role, a more likely explanation is dietary differences. In a study conducted by the National Cancer Institute of men who had been newly diagnosed with biopsy-proved prostate cancer and matched controls without prostate cancer, it was shown that increased consumption of foods high in animal fat was linked to prostate cancer (independent of intake of other calories) among black men compared with whites. The higher the intake of animal fat, the greater the risk for advanced prostate cancer. These results indicate that diet plays a major role in why black men have a higher rate of prostate cancer and show that a reduction of fat from animal sources in the diet could lead to decreased incidence and mortality rates for prostate cancer, particularly among African- Americans. In one, a total of 29,133 male smokers ages 50 to 69 from southwestern Finland were randomly assigned to receive vitamin E (50 mg), beta-carotene (20 mg), both nutrients, or a placebo for 5 to 8 years (median 6. A 32% decrease in the incidence of prostate cancer was observed among the 14,564 subjects receiving vitamin E compared with the 14,569 not receiving it. However, in the 14,560 subjects receiving beta-carotene, prostate cancer incidence was actually 23% higher and mortality was 15% higher compared with the 14,573 not receiving it. Another form of vitamin E, known as gamma-tocopherol, may prove to be more important against prostate cancer than the alpha-tocopherol form, which has been used in virtually all the vitamin E research. Eight different compounds—four tocopherols and four tocotrienols—make up the vitamin E family. They have some functions that are similar and other functions that are completely different. Alpha-tocopherol became synonymous with vitamin E for two main reasons: (1) of the eight, it is the most abundant in the human body, and (2) it is by far the most effective of the eight for what was originally thought of as vitamin E’s main function—to support reproduction. Our blood and tissue contain much more alpha-tocopherol than gamma-tocopherol despite the fact that in the typical American diet we consume twice as much gamma-tocopherol as alpha. The reason is that the liver is able to identify the alpha-tocopherol as it is absorbed from the gut and bind it to a special protein, called the alpha-tocopherol transfer protein. It recognizes the alpha- tocopherol and preferentially puts more of it in lipoproteins—proteins that carry fat and cholesterol (e. This compound and other metabolites may act to better protect the prostate from oxidative damage as well as promote apoptosis (programmed cell death), which helps prevent cells from becoming cancerous. In one study, 117 men who developed prostate cancer and 233 matched control subjects had toenail and plasma samples assayed for selenium, alpha-tocopherol, and gamma-tocopherol. For gamma-tocopherol, men with the highest levels had a fivefold reduction in the risk of developing prostate cancer compared with men with the lowest levels. The association between selenium and prostate cancer risk was in the protective direction. Statistically significant protective associations for high levels of selenium and alpha-tocopherol were observed only when gamma-tocopherol concentrations were high as well. These results indicate that in order to achieve the greatest degree of protection, natural mixed tocopherols that include both alpha- and gamma-tocopherol should be used, rather than only alpha-tocopherol. Natural forms of vitamin E are designated d-, as in d-alpha-tocopherol, while synthetic forms are dl-, as in dl-alpha-tocopherol. The prefixes d- and l- refer to two versions of the vitamin E molecule that are, in effect, mirror images of each other, the way your right hand is a mirror image of your left. Although the synthetic form has antioxidant activity, it may actually inhibit the natural form from entering cell membranes. Therefore, natural vitamin E (d-alpha-tocopherol) has greater benefit than the synthetic form (dl-alpha- tocopherol). Selenium Like vitamin E, selenium has also shown benefit in preventing prostate cancer in some studies. A 10- year cancer prevention trial found that selenium supplementation appears to significantly lower the incidence of not only prostate cancer but also lung and colon cancers in people with a history of skin cancer. The results of the study were exciting to researchers because they showed the cancer prevention potential of simply adding a nutritional supplement to a normal diet. Participants in the randomized, double-blind study took either 200 mcg of selenium per day or a placebo for four and a half years and were followed for more than six additional years. Total cancer incidence was significantly lower in the selenium group than in the placebo group (77 cases vs. While the study was planned to last 12 years, it was terminated after 7 years because no effect on the risk of prostate cancer in these relatively healthy men could be demonstrated by selenium, vitamin E, or the combination at the doses and formulations used in the study. However, our feeling is that the researchers may have been looking at the wrong form of tocopherol (see the discussion above about gamma- tocopherol). Also, other trials studying high-dose vitamin E for disease prevention have shown no benefit either. It may be that when taken at such high dosages, vitamin E loses its preventive effects. In the absence of companion antioxidants vitamin E may become a free radical itself or be unable to perform its function (see the discussion of lycopene below). The fact that selenium was ineffective in preventing prostate cancer could be due to the subjects’ having sufficient levels of selenium before the trial started. Lycopene One of the most important anticancer nutrients, especially for the prostate, is lycopene—a carotene that provides the red color in tomato products. Lycopene is one of the major carotenes in the diet of North Americans and Europeans. More than 80% of lycopene consumed in the United States is derived from tomato products, although apricots, papaya, pink grapefruit, guava, and watermelon also contribute to dietary intake. Lycopene content of tomatoes can vary significantly, depending on type of tomato and stage of ripening. In the reddest strains of tomatoes, lycopene concentration is close to 50 mg/kg, compared with only 5 mg/kg in the yellow strains. In fact, the absorption and utilization of lycopene from tomato paste or juice are up to five times greater compared with the absorption from raw tomatoes because it has been better liberated from the plant cell. Lycopene is a more potent scavenger of oxygen radicals than other major dietary carotenes, and it exerts additional anticancer effects. Lycopene’s role as a protector against prostate cancer was highlighted in a finding by Harvard researchers that of all the different types of carotenes, only lycopene was clearly linked to protection against prostate cancer. When the researchers looked at only advanced prostate cancer, the high-lycopene group had an 86% decreased risk (although this did not reach statistical significance due to the small number of cases). In a study of patients with existing prostate cancer, lycopene supplementation (15 mg per day) was shown to slow tumor growth. In subjects consuming the lycopene supplement, prostate tumors shrank and produced reduced levels of prostate-specific antigen. Researchers have also found a statistically significant association between high dietary lycopene and a lower risk of heart disease. Although lycopene supplements are available in pill form, there are excellent food sources of lycopene. For example, a 12-oz can of tomato paste contains 192 mg lycopene and costs around $1. While lycopene alone has clear benefit, it is important to point out that in a test tube study it was found that lycopene alone was not a potent inhibitor of prostate cancer cell proliferation. However, the simultaneous addition of lycopene together with alpha-tocopherol (vitamin E) resulted in a 90% decrease in cell proliferation. In the most recent study, it was shown that men deficient in vitamin D were twice as likely to suffer from more aggressive prostate cancers, but there was no evidence of an association with overall prostate cancer risk. Regular consumption of these foods and supplementation with a concentrated source of procyanidolic oligomers are recommended. Green Tea Population-based studies have demonstrated that consumption of green tea (Camellia sinensis) may offer significant protection against many forms of cancer, including prostate cancer.

This technique consists of swallowing air into the lungs order 160mg malegra fxt plus with mastercard erectile dysfunction vitamin deficiency, thus bypassing the need for respiratory-muscle strength generic malegra fxt plus 160mg on line impotence 2. A national survey in Italy in 2007 investigated long-term ventilation in children cheap malegra fxt plus 160 mg fast delivery erectile dysfunction treatment cream. A questionnaire was sent to all facili- ties that dealt with home ventilatory programmes order malegra fxt plus 160mg with mastercard does erectile dysfunction cause premature ejaculation. Investigators obtained answers regard- ing 535 patients, with an estimated prevalence of long-term mechanical ventilation of 5. Median age was 8 (interquartile range 4–14) years; me- dian age at starting mechanical ventilation was 4 (1–11) years, and 56% were boys. The most frequent diagnostic category was neuromuscular disorders (49%), followed by lung and upper respiratory diseases (18%), hypoxic (ischaemic) encephalopathy (13%) and abnormal ventilation control (12%). Noninvasive ventilation is used in 60% of Italian patients, with the remainder being ventilated through a tracheostomy. No patients in Italy are on negative-pressure ventilation; at the time of the survey, ¿ve patients were using phrenic nerve pacing, and four patients with neuromuscular disorders were us- ing glossopharyngeal breathing. There was 56% receiving ventilation only while asleep, 24% received ventilation for >20 h/day; 21% were ventilated for 12–20 h/day. Only nine (2%) patients were still living in the hospital at the time of the survey, the vast majority (98%) living at home. The gold standard for mechanical ventilation is for haemoglobin satura- tion values >95%. The end tidal carbon dioxide range may be broad, with limits of 30–45 mmHg, allowing for variation with sleep position. Other possible indications for tracheostomy ventilation are the need for 24-h/day mechanical ventilation and diagnosis of con- genital central hypoventilation syndrome [29]. Different manufacturers have created different types of equipment to connect the mechanical ventilator to the patient that minimise air leak, improve comfort and allow pa- tient synchrony with the ventilator [30]. In the clinical setting, it is recommended to have different models and types of masks available in order to ¿nd the best ¿t for each patient [33]. Sensitivity triggering inspiration of most ventilators is insuf¿cient for infants breathing through the mask in the presence of leaks [34]. The nasal mucosa loses water delivered to the inspiratory gas, leading to an increase in nasal airway resistance, which in adults has been shown to increase up to six times the baseline value [35]. Because the older child is no longer an obligatory nose breather, this could lead to mouth breathing and associated air leaks [36]. One must consider that the presence of a humidi¿er will increase the resistance of the circuit and interfere with trig- gering and pressure delivery. They can manifest even after a few hours if the mask is not properly dressed and can be so severe as to create perma- 92 G. A preventive approach is needed and will consist in continuous monitoring provided by an expert maxillofacial surgeon and a strategy of rotating different types of masks avoid ap- plying pressure at the same points. The tracheostomy allows more reproducible parameters of mechanical ventilation with measurable volumes and settable alarms. If the cannula is not cuffed, as is usually the case in children, and if leaks are consistent, ventilation through the cannula may present similar dif¿culties as those experienced with the mask. Caregivers must be aware of the two most severe and common complication that can occur during tracheal ventilation in children: dislocation; and cannula plugging. Caregivers must be trained to recognise and solve these problems; moreover, it must be made very clear that children with tracheostomy can only be with people who are able to treat these events, which if not promptly and effectively treated, may cause severe complications and even death [38]. Pressure-limited ventilation with volume guarantee is available with several portable mechanical ventilators. This of- fers the possibility of compensating for the leaks that occur when using uncuffed cannula, together with the availability of increasing ventilation pressure to guarantee a minimum preset tidal volume in the presence of obstruction, for example, for tracheal secretions. Such ventilators offer two different modes by which to deliver a target volume during pressure-limited ventilation: dual control mode within a breath; and dual-control mode, breath to breath. Nonrespiratory Problems Feeding Children affected by chronic respiratory failure needing home mechanical ventilation of- ten suffer feeding problems too: many need enteral feeding, as problems of swallowing are often present. Children affected by sever pulmonary diseases such as bron- chopulmonary dysplasia, manifest continuous dyspnoea with increased intrathoracic de- pression. They can be treated with medical support, such as antacid and prokinetic drugs, but frequently they need even more invasive manoeuvres, such as duodenal jejunal feeding or antireÀux surgery (gastrooesophageal Nissen fundoplication, etc. Failure to swal- low requires accurate diagnosis and appropriate treatment, as it represents severe impair- ment for the child’s social integration within the family and at school. Children on long-term ventilation and, in particular, children with tracheostomies, may spend weeks without ingesting anything per os. This limitation must be counteracted, and a quick oral feeding, even with a small amount of food, will avoid future impairment. In the presence of already established dis- ease, prompt intervention by the logopaedist will be needed to try to rehabilitate the lack- ing function. A narrow tracheal cannula will facilitate the use of the speaking valve, which allows phonation and permits better movement of the air through the vocal cord and a more prompt reÀex of swallowing [42]. The mode of respiratory support needed will probably inÀuence the patient’s capacity to move. This point will be crucial for their quality of life: some may be better supported with tracheal ventilation if bulbar weakness is severe. Comprehensive treatment directed to care of movement and position is of great con- cern: children with lengthy hospitalisation, often from birth, will probably experience lack of stimulation. Hopefully in such cases, a preventive approach is initiated consist- ing in 24-h/day free access to the unit for the parent. Moreover, a rehabilitation specialist will be involved early with the baby, identifying possible de¿cits and working with and teaching parents how to interact with their child. They have the sensation of less gravity and experience some movements that they are commonly unable to perform. Special technologies are Micro Light, Egg Switch, Zero Touch Switch, Infrared Switch [44]. Prevention of scoliosis is achieved with postural hygiene and proper building and use of the corset. Close attention must be paid to the development of the spine, in particular during school age and adolescence. In the pres- ence of an increase of the Cobb angle >30°, the surgical approach must be considered. Also, art 53 of leg- islative decree 151/2001 states that individuals who care for an individual with a disability, as per law 104/1992, do not need to work nights, and therefore can apply for a “nights on call exemption”. Parents can modify quantity and timing of nutrition according to periods of sleep, respiratory fatigue and increased need of cough assist; 4. They are allowed to increase ventilation pressures to a maximum of 25 cm water (H2O) and to increase the respiratory rate. Then they are taught that the inspiratory pressure can be increased to obtain good chest rise and that, however, pressure must be maintained <40 cm H2O. This is necessary to verify the patient’s health conditions, both respiratory and general. During the follow-up visit, which commonly takes 2–3 days, the main aspects are to: (1) consider the condition of the family, e. It is important to verify the presence of both hyper- and hypocapnia and the possible negative conse- quence of the latter [46]. Moreover, it is important to remember that low SpO2 can indicate the presence of hypercapnia, but hypocapnia can easily go unrecognised without good monitoring. The decision to start support to maintain life in such a severe disease is very dif¿cult. Concern exists about the opportunity to prolong life with arti¿cial means and the risks of prolonging also the patient’s suffering without option of care. The decision as to whether to offer long-term ventilation to parents of such patients is dif¿cult and complex. Although the level of disability is very severe, it is dif¿cult to accurately “estimate” the patient’s quality of life. This was in stark contrast to 67 physicians who estimated these patients’ quality of life at 2. Notably, almost 80% of physicians felt that the decision to initiate long-term ventilation should rest solely with them rather than with the patient’s family. The critical question physicians must continually ask themselves is whether our patient’s quality of life and, in particular, the bene¿ts that he/she gains from being kept alive, is outweighed by the suffering experienced as a result of the underlying disease and its treatment. It is often very dif¿cult to make parents fully aware of their child’s condition, both at the time of diagnosis and upon ¿rst clinical symptoms. It is different after several years, as the child will change as the condition and its associated problems change, which are main- ly related to joint deformities. We give parents the opportunity to see movies of children affected by the same disease and putting them in contact with families in similar situations through direct contact and contact with family associations and social networks. Those children will suffer pain and have to deal with tubes, machines, alarms and panic situations. Frequently, they will not be able to walk, run, swim or jump; and some will not be able to speak or move at all. The child’s condition will change the parents’ and siblings’ lives as well, often leaving little free time – perhaps even no time to read a book or attend a medical visit. Singles with a child with such a severe condi- tion and who must work for living will be obliged to leave the child in the hospital. The majority of these children will suffer the disease with little treatment available, and some will probably die as a consequence. Nevertheless, such situations are part of life and our world; happiness and sadness do not depend exclusively on illness or wellness but lie in our hearts and in how we feel about each other, particularly about our needful neighbour.
