Pregnancy-associated neuromyelitis optical spectrum disorder combined with primary Sjögren's syndrome: A critical illness case report / 北京大学学报(医学版)

Central nervous system involvement in primary Sjögren's syndrome (pSS) is less common and usually presents as white matter lesions, neuromyelitis optica spectrum disorder (NMOSD), or transverse myelitis. NMOSD is an immune-mediated inflammatory demyelinating disease of the central nervous system with a high rate of relapse and significant disability. Studies have shown that patients with pSS combined with NMOSD have more severe symptoms and poorer prognosis. Here, we present a case of critical illness in pregnancy-associated NMOSD combined with Sjögren's syndrome. The patient was a 30-year-old pregnant woman with a history of Sjögren's syndrome who was diagnosed with NMOSD. She received combination therapy with steroids, intravenous immunoglobulin (IVIG), and hydroxychloroquine during pregnancy, resulting in partial resolution of numbness below the waist. However, due to irregular medication adherence outside the hospital setting, she developed weakness in her right lower limb accompanied by inability to move it, while her left lower limb still had some mobility but occasional numbness along with urinary and fecal incontinence. Ten days later, she was admitted to the emergency department where an emergency cesarean section was performed to deliver a healthy baby boy. However, her condition worsened postpartum as she developed high fever accompanied by bilateral lower limb paralysis and weakness along with loss of voluntary control over urination and defecation. The patient underwent ano-ther course of treatment consisting of steroids and IVIG; however there was limited improvement in symptoms observed after this intervention. Following administration of rituximab for the first time, the patient developed urinary tract infection which was successfully managed before continuing regular infusions. In later stages the patient could walk slightly with a limp and regained control over urination and defecation, allowing her to resume normal activities. This case suggests that combination therapy with steroids, IVIG, and hydroxychloroquine should be considered for the patients with pregnancy-associated NMOSD combined with Sjögren's syndrome. Rituximab can significantly improve symptoms such as postpartum paralysis in patients with NMOSD, however, there may be a risk of infection associated with its use.

Brachial Plexus Injuries with Ulnar Musculocutaneous Transfer: 78 Cases Study Focused on Possible Postoperative Complications

Objective To analyze 78 cases of brachial plexus injury submitted to the Oberlin technique between 2003 and 2012. The potential complications of this technique were analyzed, especially motor damage or hypoesthesia of the hand. Method Medical records from patients with brachial plexus injuries at the levels of the C5-C6 and C5-C6-C7 vertebrae were retrospectively analyzed. Cases submitted to the Oberlin procedure with or without concomitant brachial plexus procedures between 2003 and 2012 were evaluated. The minimum follow-up period was of 1 year. In addition to the clinical examination, electromyography and magnetic resonance imaging (MRI) of the brachial plexus were used to diagnose and locate the nerve damage. Results A total of 78 surgical patients met the inclusion criteria. Postoperative neurological changes, mostly transient, were observed in 18 patients. Hypoesthesia in the ulnar side of the handwas observed in seven cases; neuropathic pain in five cases; allodynia in four cases, and hand motor loss in two cases. Conclusion Based on the results of the present case series, we conclude that there are few sequelae in the donor nerve territory compared with the benefit of the Oberlin technique on the recovery of elbow flexion after brachial plexus injuries.

Anestesia congênita de córnea associada à anestesia de ramo do trigêmio: relato de caso / Congenital corneal anesthesia related to trigeminal anesthesia: case report

A anestesia corneana por ser uma condição rara, freqüentemente é confundida ou não diagnosticada durante o exame de rotina do segmento anterior. Relato de caso de um paciente de 18 anos encaminhado ao ambulatório de córnea e doenças externas com quadro clinico de síndrome de olho seco e com diagnóstico provável de síndrome de Sjõgren. Era amblíope de olho direito devido à opacidade corneana no eixo visual secundária a trauma com unha na infância. Foi pesquisada sensibilidade corneana que era ausente em ambos os olhos; olho seco grave e com BUT (tempo de quebra do filme lacrimal) menor que 4 segundos. Foi feito diagnóstico de anestesia corneana congênita associada a hipoestesia do nervo trigêmio pela avaliação neurológica da sensibilidade facial e movimentos bruscos do queixo que evidenciavam alterações sensoriais do nervo. O oftalmologista geral e principalmente o especialista em segmento anterior devem ter como rotina a pesquisa da sensibilidade corneana no exame do segmento anterior.

Osteoarticular complications in anaesthetic foot.

A clinico radiological comparative study of complications in the anaesthetic foot in 60 patients (48 leprosy and 12 spinal injuries) were done. It has been observed that these groups behave differently.
