Chiropractic Manipulation: Reasons for Concern?

Chiropractic's popularity is rising among the general population. Moreover, few studies have been conducted to properly evaluate its safety. We report three cases of serious neurological adverse events in patients treated with chiropractic manipulation. The first case is a 41 years old woman who developed a vertebro-basilar stroke 48 h after cervical manipulation. The second case represents a 68 years old woman who presented a neuropraxic injury of both radial nerves after three sessions of spinal manipulation. The last case is a 34 years old man who developed a cervical epidural haematoma after a chiropractic treatment for neck pain. In all three cases there were criteria to consider a causality relation between the neurological adverse events and the chiropractic manipulation. The described serious adverse events promptly recommend the implementation of a risk alert system.

Falsos Negativos em Citologia Cervical. A Propósito de um Caso Clínico

A redução na incidência e morbimortalidade do cancro do colo invasivo deveu-se, e deve-se, ao diagnóstico e terapêutica das lesões precursoras do cancro cervical, contribuindo para este objectivo a implementação de métodos e programas de rastreio eficazes com citologia cervical. É do conhecimento geral que a citologia cervical é um método de rastreio eficaz mas apresenta limitações. Os falso negativos podem atingir mais de 50%, uma taxa de 5 a 10% é considerada aceitável pela maioria dos autores. Taxas inferiores a 5% são apresentados nas melhores séries. Como a citologia é um exame de rastreio e não um teste diagnóstico, se a sintomatologia e/ou a clínica sugerirem patologia, a investigação deverá prosseguir, mesmo na presença de citologia negativa. O caso clínico que se apresenta ilustra e pede atenção para a problemática dos resultados falsamente negativos da citologia cervical.

Neurogenic Thoracic Outlet Syndrome Associated with Cervical Rib

A true neurogenic thoracic outlet syndrome (TOS) associated with a cervical rib is considered extremely rare. The authors present their experience with 5 cases of true neurogenic TOS associated with a cervical rib. All patients were female and had a cervical rib confirmed radiographically pre-operatively. Average age was 34,8 years. Although all patients had been treated with several combinations of diverse drugs and a rehabilitation program before referral to surgery, all described their pain as intense and debilitating before surgical treatment. All patients had pre-operative electromyographic abnormalities. Patients were operated on via a supraclavicular approach and the cervical rib was resected. No intra-operative or postoperative complications were noted. Two years postoperatively, all patients mentioned improvement. However, only 2 were symptomless, and on no medication. In one patient there was significant improvement, and in the remaining 2 patients some residual pain persisted that had to be dealt with pharmacologically. All patients were able to resume their daily life activities. Recovery was poorer in the 2 patients that had been referred to surgery after a longer period of time since the beginning of symptoms.

Cerclage Cervical na Gravidez

Os autores efectuam uma revisão de 78 cerclages do colo uterino realizadas na Maternidade Dr. Alfredo da Costa, num período de oito anos (1991-1998). A técnica utilizada foi a de Mc Donald, com excepção de um caso em que se utilizou a técnica de Shirodkar. No passado obstétrico destas 78 grávidas houve 181 gravidezes anteriores com uma sobrevida fetal de 17%. Após a cerclage, a sobrevida fetal foi de 83%, com um prolongamento médio da gestação de 17 semanas. O resultado final da gravidez foi de 8% de abortos, 37% partos pré-termo (PPT) e 55% de partos de termo (PT).
