The pathology is caused by absence or extreme deﬁciency of a large cytoskeletal protein 20mg cialis jelly for sale, dystrophin buy cialis jelly 20 mg with amex, encoded in the Xp21 region. This protein attaches to the inner surface of the muscle ﬁber membrane as a part of a complex of glyco- proteins. Dystrophin also is part of the inner membrane structure of smooth and cardiac muscle and of certain cells in the central nervous system and in specialized connective tissues, such as the myotendinous junctions. This distribution of dystro- phin corresponds closely to those tissues with major damage in Duchenne dystrophy. Parents notice weakness of forward head ﬂexion that persists beyond infancy, accompanied by slowed motor development. Patients have difﬁculty keeping up with their peers, both physically and sometimes cognitively. Diagnosis hinges on careful history and physical, as well as laboratory testing (i.

Treatment The overall goals in managing patients who have Duchenne dystrophy are to main- tain ambulation for as long as possible, to optimize the development of the patient’s cognitive abilities, and to anticipate the occurrence of complications, such as exces- sive weight gain, joint contractures (especially of the Achilles tendons), respiratory insufﬁciency, scoliosis, gastrointestinal hypomotility, and occasionally cardiomyopa- thy. The patient and his family need to work closely with the physicians, schoolteachers, physical educators, and physical and occupational therapists to develop an individualized care plan for each stage of Duchenne dystrophy. Early in the illness the patient usually can play with his peers in most activities, but by the ﬁrst or second grade some adaptation of physical education requirements becomes necessary. Orthopedic Concerns The natural history of Duchenne dystrophy predicts that the patient will become wheelchair bound between 10 and 12 years of age. Often, lightweight long-leg bra- cing is helpful at this stage to prolong weight bearing and ambulation, both of which delay the development of joint contractures and scoliosis. Contractures and scoliosis develop primarily after the patient becomes wheelchair bound.

CHOOSING A VENUE It is extremely important to make sure you choose the right venue for your focus group as this will aﬀect parti- cipation levels, the level of discussion and the standard of recording. You should ask yourself the following ques- tions when considering a venue: X Is the venue accessible in terms of physical access for those with mobility diﬃculties? X Is it accessible in terms of ‘mental’ access, that is, would the type of people you intend to recruit feel comfortable entering that building? X Is the room big enough to accommodate the number of people you intend to recruit? X Is there anything which could distract the participants (loud noises, telephones, doorbells, people entering the room, people walking past windows, etc)? Once you have chosen your venue, you need to arrive early to make sure that the seating is arranged in an appropri- ate manner. There is no set rule for this – think about your participants and arrange it accordingly. For exam- ple, business people might prefer a boardroom style seat- ing arrangement, whereas adult learners may prefer an informal seminar style arrangement. RECRUITING YOUR PARTICIPANTS Without participants you have no focus group. It is essen- tial, therefore, that you take time to ensure that you achieve a high turn out for your focus group. Think about the following points when recruiting your participants: X The ideal number of participants is nine or eleven. Odd numbers work better than even numbers as it is harder for people to pair up in breakaway conversations. X Over-recruit by between three and ﬁve people as some participants, despite reassurances to the contrary, will not attend. If you cannot aﬀord to pay partici- pants, oﬀer refreshments such as wine, soft drinks and nibbles.
