Children with HCP have significant side-to-side limb-length discrepancy when compared with control children. The discrepancy increases with age. The extent of shortening did not appear to be related to upper extremity function and spasticity. The extremity shortness showed a relation to hand function.
Background/Objectives: Clonus is an involuntary rhythmic muscle contraction after sudden muscle stretch that occurs as a result of a lesion in the upper motor neurons. The real mechanism behind clonus remains obscure. The objective of this study was to investigate the effects of central-acting tizanidine treatment and peripheral extremity cooling on clonus. Participants: Thirty-eight patients with upper motor neuron involvement and sustained clonus. Methods: The 38 patients were divided into 3 groups: cold group (n ¼ 19), tizanidine group (n ¼ 13), and patient control group (n ¼ 6). A separate group of 21 able-bodied volunteers served as controls for the cold group. The physiologic effects of cold application were measured in the able-bodied group and compared with the effects in the patients in the cold group. All participants were evaluated by clinical and electrophysiologic measurements. Results: Changes in clinical and electrophysiologic measurements in the cold group were statistically significant compared with those of the tizanidine and patient control groups. Conclusions: Subsequent and long-term cold application induced prolonged inhibitory effects on clonus. Tizanidine had no significant effect on clonus. Suppression of clonus by cold highlights the importance of peripheral input in relation to central mechanisms.
A total of 73 patients with obstetric brachial plexus palsy and extremity shortness were evaluated clinically, electrophysiologically, and with cervical magnetic resonance imaging. Patients were separated into groups according to age and the level of lesion. The differences of the length of the humerus, ulna, radius, and the second and fifth metacarpal bones were significant between the involved and uninvolved extremities. The difference in shortness increased in relation to the age of the groups and stabilized to approximately 10% in the groups aged 4 to 8 years and 8+ years. A significant relationship was observed between bone length differences and lesion levels. Differences in bone lengths were statistically significant in patients with avulsion in the group aged 8+ years. Extremity shortness appears to be related to avulsion and the level of lesion. The effect of avulsion on extremity shortness gradually increases with age. Finally, root avulsion can be an important factor in extremity shortness of obstetric brachial plexus palsy patients.
By this case, it is emphasized that spinal hydatid cyst should come to mind in the differential diagnosis of spinal cord compression, and the importance of prevention, early diagnosis, and treatment is highlighted because of high mortality and morbidity.
Complex regional pain syndrome (CRPS) type I is a clinical condition characterized by persistent pain in one part or the entire extremity after a minor trauma, fracture, or after an operation which does not involve nerve damage and/or sympathetic hyperactivity. Despite large-scale studies on the complications that arise after burns, literature reveals few reports on neurological problems and CRPS developing after burns. It is a rare complication of a burn injury to an extremity. Its early signs and symptoms are similar to those of burn wound itself. This study describes an unusual cause of complex regional pain syndrome in burn patients. The report highlights physical examination findings, the new diagnostic criteria of complex regional pain syndrome, and difficulties in diagnosis.
The purpose of this retrospective study was to analyze the effect of peripheral nerve injury on the skeletal maturation process. The bone ages of the affected and unaffected hand-wrists of 42 children with obstetrical brachial palsy were determined according to the Greulich and Pyle atlas. In 23 patients, the bone ages of the both sides were identical (bone-age-symmetrical group), in 19 patients the bone age of the affected side was delayed (bone-age-delayed group). The mean bone age of the affected side was delayed 0.48 ± 0.25 years that of the unaffected side (P = .000), and the delay of bone age was inversely correlated with chronological age (R (2) = .45, P < .02) in the bone-age-delayed group. Skeletal retardation can be recognized after appearance of ossification centers by plain radiography, dating from the third month of life, in early infancy. Thus, bone age determination method might be helpful for predicting potential future limb shortness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
