In the UK order 10 mg rizatriptan mastercard, tuberculosis is associated particularly with the immigrant population (especially from Asia buy 10mg rizatriptan otc, Africa and Latin America), the homeless, the elderly and the immunosuppressed (e. In children, tuber- culosis infection is typically due to prolonged and close contact with an indi- vidual having active and untreated disease. The radiographic appearances of pulmonary tuberculosis are varied and dependent upon the age of the child. Progressive pulmonary tuberculosis most commonly occurs during infancy as a result of the primary infection not being contained, and subsequently progresses to bronchopneumonia, lobar pneumo- nia (usually middle or lower lobe) and cavitation. In contrast, primary pul- monary tuberculosis in older infants and children is usually an asymptomatic illness with minimal abnormalities demonstrated on the chest radiograph, while adolescent infection will follow more closely the typical adult appearances with upper lobe opaciﬁcation and possible cavitation. Widespread haematogenous dissemination of tuberculosis following primary infection is uncommon and is 9 normally restricted to children under 2 years of age (Fig. AIDS (acquired immunodeﬁciency syndrome) The lungs are a common site of infection in the immunocompromised child and consequently over 50% of AIDS-related paediatric mortalities have pulmonary 5 disease (Fig. The radiographic appearances of AIDS-related paediatric 38 Paediatric Radiography Fig. The chest wall and pleura Scoliosis When severe, scoliosis may result in respiratory dysfunction as a consequence of a marked curvature of the thoracic spine and associated chest wall deformity restricting normal thoracic inspiratory and expiratory movement. Signiﬁcant loss of inspiratory capacity may lead to pulmonary hypertension, recurrent infection, atelectasis and respiratory insufﬁciency. Pectus excavatum Pectus excavatum (funnel chest) is depression of the sternum and results in a reduction in the antero-posterior diameter of the thoracic cavity (Fig. As a consequence, there is insufﬁcient room for the heart to lie in its normal position Fig. If not identiﬁed clinically at the time of examination, pectus excavatum can be suspected radiographically if the anterior ribs are seen sloping steeply on the postero-anterior projection of the chest.

The teratological series in symbrachydactyly is as Treatment follows (with increasing severity of the damage): short- The following surgical options are available: finger type, monodactylous type, split hand type and stabilization of the finger buds with free bone grafts, peromelia type. A crucially important factor is Lengthening osteotomies are an effective option for whether the thumb is opposable and whether a pinch grip achieving functional improvement and, in some cases, is possible. Knowledge of the age at which the ossification a cosmetic benefit as well.

Thus, for example, the lengthening of an extremely short forearm stump will allow objects to be wedged in the elbow or pro- duce a better fit for a forearm prosthesis (⊡ Fig. Age at which the ossification centers appear on the x-ray of the hand Even the surgical lengthening of the phalanges can produce a functional improvement if it facilitates opposi- Ossification center Age tion and thus a pinch grip.

Since this patient was unable to wedge objects in her elbow, a stump lengtheningprocedure with the Ilizarov apparatuswas performed at 15 years of age.
