RESUMEN

Abstract Objective Given the divergence of opinions on the need for complementary tests such as ultrasonography (US) and electroneuromyography (ENMG) for the diagnosis of carpal tunnel syndrome (CTS), we aimed to elucidate which of them presents greater accuracy for the confirmation of the presence or not of this condition. Methods A total of 175 patients from a hand surgery outpatient clinic were clinically evaluated, and the results of clinical trials (Tinel, Phalen and Durkan), US (normal or altered), and ENMG (normal, mild, moderate and severe) were noted, crossed, and submitted to a statistical analysis to verify the agreement between them. Results with the sample had a mean age of 53 years, with a prevalence of female patients (159 cases). Of the patients with positive clinical test, 43.7% had normal US and 41.7% had no alterations on the ENMG. Negative results were found on the Tinel in 46.9%, on the Phalen in 47.4%, and on the Durkan in 39.7%. In the crossing between the results of the ENMG and those of the other diagnostic methods, there was little statistical agreement between them. Conclusion There was no agreement between the results of the clinical examinations, the US and the ENMG in the diagnosis of CTS, and there is no clinical or complementary examination for CTS that accurately determines the therapeutic approach. Level of Evidence IV, Case Series.


Resumo Objetivo Diante da divergência sobre a necessidade de exames complementares, como ultrassonografia (US) e eletroneuromiografia (ENMG) para o diagnóstico da síndrome do túnel do carpo (STC), objetivamos elucidar qual deles apresenta maior precisão na confirmação da presença ou não desta afecção. Métodos Um total de 175 pacientes de um ambulatório de cirurgia da mão foram avaliados clinicamente, e os resultados dos testes clínicos (Tinel, Phalen e Durkan), da US (normal ou alterada) e da ENMG (normal, leve, moderada e grave) foram anotados, cruzados, e submetidos a análise estatística para verificar a concordância entre eles. Resultados A idade média da amostra era de 53 anos, sendo prevalente o sexo feminino (159 casos). Dos pacientes com teste clínico positivo, 43,7% apresentavam US normal, e 41,7%, ENMG sem alterações. Foram encontrados resultados negativos no Tinel em 46,9% no Phalen em 47,4%, e no Durkan em 39,7%. No cruzamento entre a ENMG e os demais métodos diagnósticos, houve pouca concordância estatística. Conclusão Não houve concordância entre os resultados dos exames clínicos, da US e da ENMG no diagnóstico da STC, e não há exame clínico ou complementar para STC que determine a conduta terapêutica com precisão. Nível de Evidência IV, Série de Casos.

RESUMEN

El síndrome de atrapamiento del nervio supraescapular es una causa infrecuente de dolor en el hombro y de difícil diagnóstico clínico. Puede ser consecuencia de traumatismo, infección, compresión extrínseca o estiramiento secundario a movimientos repetitivos. Los quistes supraglenoideos deben considerarse en el diagnóstico diferencial pues son una causa frecuente de compresión del nervio supraescapular que ocurre casi exclusivamente en hombres. Se evaluaron con resonancia magnética (RM) y en forma retrospectiva siete pacientes con diagnóstico de atrapamiento del nervio supraescapular por quiste supraglenoideo. La RM mostró la causa y localización de la compresión nerviosa así como la distribución del edema muscular en todos los casos. Puede evaluar el grado de severidad de la enfermedad y realizar el diagnóstico diferencial con otras causas que provocarían atrapamiento del nervio supraescapular. (AU)


Suprascapular nerve entrapment has been regarded as a relatively uncommon condition that is easily overlooked in the differential diagnosis of shoulder discomfort. The common feature is nerve damage, caused either by trauma, extrinsic compression or by stretching secondary to repeated movements. Ganglion cysts account for the majority of the masses causing entrapment and seem to occur exclusively in men. Seven cases of suprascapular nerve entrapment caused by supraglenoid cyst compression were reviewed with MRI. MRI showed the cause and location of nerve compression as well as the distribution of muscular edema in all cases. MR imaging also allows an evaluation of the severity of the disease. It is also very efficient in excluding several differential diagnoses. (AU)

RESUMEN

We identified Charcot-Marie-Tooth disease type 1A (CMT1A) in a family with schwannomas in the spinal cord and median nerve. The CMT1A in this family showed an autosomal dominant pattern, like other CMT patients with PMP22 duplication, and the family also indicated a possible genetic predisposition to schwannomas by 'mother-to-son' transmission. CMT1A is mainly caused by duplication of chromosome 17p11.2-p12 (PMP22 gene duplication). A schwannoma is a benign encapsulated tumor originating from a Schwann cell. A case of hereditary neuropathy with liability to pressure palsies (HNPP) concurrent with schwannoma has been previously reported. Although it seems that the co-occurrence of CMT1A and schwannomas in a family would be the result of independent events, we could not completely ignore the possibility that the coincidence of two diseases might be due to a shared genetic background.

RESUMEN

The supracondylar process of the humerus is a rare skeletal anomaly, which is usually an incidental finding while an X-ray is done for some other purpose. The process can fracture resulting in pain and tender mobile swelling over the medial aspect of the arm, and consequent neurovascular symptoms, or entrapment neuropathies. The anomaly, which fractured in a clinical situation, is described, followed by a review of the literature

RESUMEN

Distal polyneuropathy is the most common neurologic complication of diabetes mellitus. Prolongation of H-reflex latency could be demonstrated at time when convential motor nerve conduction study may not show an abnormality. The aim of this work was to compare motor conduction study with H-reflex latency in diagnosis of diabetic neuropathy. This study was carried out on 44 patients with diabetes mellitus of both type 1 and type 2, they were 26 males with mean age 47.5 years and 18 females with mean age 43.4 years. A control group of 10 healthy subjects were chosen, six were males and 4 were females, the two groups were matched together as regard the age and sex. The patients and control groups were subjected to thorough clinical evaluation and electrophysiological testing for distal latency of the median and lateral popliteal nerves and their motor nerve conduction velocity as well as the H-reflex latency. Correlations between H-reflex and other variables including motor conduction velocity and type of diabetes were done. The results were: 30 cases showed peripheral sensory affection while 14 patients showed no symptoms of sensory affection, 27 patients showed motor manifestations, 6 patients showed cranial nerve affection and 5 patients showed manifestations of autonomic dysfunctions. The electrophysiological tests showed highly significant difference between control and patients groups regarding median nerve distal latency, median and lateral popliteal nerves motor conduction velocity and very highly significant difference between control and patients groups in H-reflex latency. Comparing H-reflex latency with motor nerve conduction velocity revealed significant superiority of H-reflex latency on motor conduction velocity in both clinical and subclinical cases of diabetic neuropathy. We concluded that H-reflex latency is of great diagnostic value in diabetic neuropathy. Furthermore, it is more sensitive than conventional motor nerve conduction study
