Bladder ultrasonography in the assessment of cauda equina syndrome in the emergency department: a literature review.

For cauda equina syndrome (CES), current clinical assessment in the emergency department usually involves perianal sensation (PAS) and anal tone (AT). Neither reliably predict magnetic resonance imaging (MRI) demonstrating a large central disc prolapse (MRI+). Other clinical examination findings increase the probability of MRI+. Other tests of sacral nerve root function include anal squeeze (AS) and the bulbocavernosus reflex (BCR). If BCR, PAS and AT, and AS are combined and they are all normal, CES can be excluded in almost all cases. Portable bladder ultrasonography is now commonly used to assess bladder function, particularly in measuring the post-void residual urinary volume (PVR). PVR is deemed normal at <50ml. If the PVR is <200ml and there are no objective signs, MRI+ is rare. If the PVR is >200ml, MRI+ is found in 43% of cases. The combined assessment of PAS, AT and AS (and BCR in selected cases) and PVR increases the specificity and sensitivity of a clinical diagnosis of CES (i.e. maximising MRI+ and minimising MRI-). Recommendations for when to perform MRI are made.

Chronic cauda equina syndrome decompression surgery recovery is very "bad"? Based on patient self-assessment.

BACKGROUND: Symptoms of cauda equina syndrome (CES) secondary to degenerative lumbar spine diseases are sometimes mild and tend to be ignored by patients, resulting in delayed treatment. In addition, the long-term efficacy of surgery is unclear. OBJECTIVE: To determine the predictive factors of CES and post-operative recovery in patients with symptoms lasting > 3 months. METHODS: From January 2011 to December 2020, data of 45 patients with CES secondary to lumbar disk herniation/lumbar spinal stenosis were collected from a single center. The patients had bladder, bowel or sexual dysfunction and decreased perineal sensation that lasted for > 3 months. A 2-year post-operative follow-up was conducted to evaluate recovery outcomes, which were measured by validated self-assessment questionnaires conducted by telephone and online. RESULTS: Overall, 45 CES patients (57.8% female; mean age, 56 years) were included. The duration of pre-operative CES symptoms was 79.6 weeks (range, 13-730 weeks). The incidence of saddle anesthesia before decompression was 71.1% (n = 32), bladder dysfunction 84.4% (n = 38), bowel dysfunction 62.2% (n = 28) and sexual dysfunction 64.4% (n = 29). The overall recovery rate of CES after a 2-year follow-up was 64.4%. The rates of the residual symptoms at the last follow-up were as follows: saddle anesthesia 22.2%, bladder dysfunction 33.3%, bowel dysfunction 24.4% and sexual dysfunction 48.9%. Pre-operative saddle anesthesia, overactive bladder and sexual dysfunction were risk factors for poor prognosis after decompression. CONCLUSION: CES patients with symptoms lasting > 3 months may recover after surgery. Sexual dysfunction has a high residual rate and should not be ignored during diagnosis and treatment.

Clinical and epidemiological features of Lyme neuroborreliosis in adults and factors associated with polyradiculitis, facial palsy and encephalitis or myelitis.

The clinical course of Lyme neuroborreliosis (LNB) is highly variable. Delayed diagnosis and treatment still remain actual challenges. Moreover, there is a lack of studies analyzing the factors associated with different LNB syndromes. We aimed to analyze clinical and epidemiological features of LNB in hospitalized adults in eastern Lithuania. A retrospective study was performed for patients presenting in the years 2010-2021. A total of 103 patients were included in the study, 100 with early, and three with late LNB. Patients with early LNB most often presented polyradiculitis [75/100, (75%)], which was also the most common initial neurological syndrome. Peripheral facial palsy was diagnosed in 53/100 (53%) patients, in 16/53 (30.2%) cases both facial nerves were affected. Encephalitis or myelitis was diagnosed in 14% of patients with LNB. A total of 76/103 (73.8%) patients were discharged with residual symptoms or signs. One patient presenting encephalomyelitis died because of bacterial complications. The absence of observed erythema migrans (EM) was the predictor of peripheral facial palsy, while female sex and EM untreated with antibiotics were predictors of isolated polyradiculitis. A fever of ≥ 38 ° °C and pleocytosis of ≥ 300 × 106/l were associated with the development of encephalitis or myelitis in patients with early LNB.

Triangular Osteosynthesis as a Treatment of Lumbopelvic Dissociation with Acute Cauda Equina Syndrome in an 11-Year-Old Patient.

This case offers a safe and effective method for treating lumbopelvic dissociation in a pediatric patient with cauda equina syndrome using a triangular osteosynthesis construct. After a high-speed accident, an 11-year-old girl was admitted to the hospital with bowel and bladder incontinence and bilateral lower extremity weakness. The orthopaedic trauma and spine teams elected for surgical treatment with a triangular osteosynthesis construct, a procedure usually reserved for adults. The surgery was uncomplicated, and the patient experienced complete resolution of her preoperative symptoms. She is doing well over 1-year postoperatively, with full neurologic recovery, maintained reduction, bony healing, and subsequent implant removal. To our knowledge, this is the youngest reported case of lumbopelvic dissociation treated in this manner and represents a viable treatment option.

Anterior lumbosacral polyradiculoneuropathy following intrathecal methotrexate administration: a case report and literature update.

INTRODUCTION: We describe a case of intrathecal methotrexate toxicity and perform a literature review of existing cases. CASE PRESENTATION: A 23-year-old man who received diagnosis of acute lymphoblastic leukemia and started chemotherapy according to the LAL1913 protocol underwent CNS prophylaxis with intrathecal methotrexate. About 1 month after, he developed a flaccid paraparesis. CSF analysis showed albumin/cytological dissociation. Spinal MRI showed thickening of the ventral roots of the cauda equina with contrast enhancement. Nerve conduction studies showed severe lower limb motor axonal neuropathy. Needle examination showed acute denervation involving L3-S1 roots. Methotrexate was stopped, and the patient was treated with intravenous immunoglobulins, followed by high-dose intravenous methylprednisolone, with a gradual improvement. Three months later, the spine MRI was normal. Electrophysiological and imaging findings were indicative of pure motor L3-S1 polyradiculopathy. DISCUSSION: Literature review of existing cases confirm the relatively selective involvement of lumbosacral ventral roots in intrathecal methotrexate toxicity. Pathophysiologic mechanisms suggest either a direct toxicity with localized folate deficiency or an immune-mediated mechanism, the latter consistent, in our patient, with the albumin/cytological dissociation and response to immunomodulatory treatments. Pure motor polyradiculopathy of the lower limbs is rare but predictable complication of intrathecal methotrexate, which can benefit from early withdrawal and immunomodulatory treatments.

Chronic inflammatory demyelinating polyneurophaty: assessment of the cognitive function and quality of life.

BACKGROUND: Studies were carried out with the objective of evaluating the quality of life (QoL) of patients affected by chronic inflammatory demyelinating polyradiculopathy (CIDP). However, the cognitive issue is still little addressed. OBJECTIVES: To assess the QoL and cognitive impairment of patients with CIDP and to analyze whether there is a correlation between these parameters. METHODS: Seven patients with CIDP and seven paired controls were subjected to: mini-mental state examination (MMSE); Montreal cognitive assessment (MoCA); digit symbol replacement/symbol copy test (DSST); fatigue severity scale (FSS); Beck depressive inventory-I (BDI-I), and a short-form of health survey (SF-36). RESULTS: The mean age of the participants was 50 years (71.4% male). The MMSE and MoCA had no statistical difference between the groups. Patients showed superior results in the memory domain in the MoCA (5 vs. 2, p = 0.013). In the DSST, we observed a tendency for patients to be slower. There was a strong negative correlation between fatigue levels and vitality domain (SF-36). There was no significant correlation between depression levels and QoL, and there was no correlation between depression and the results obtained in the cognitive tests. The patients presented higher levels of depression (15.28 vs. 3.42, p < 0.001). A total of 57% had severe fatigue, 28.8% self-reported pain, and 57.1% complained of cramps. CONCLUSION: There was no cognitive impairment in these patients. However, there was a tendency of slower processing speed. To better evaluate the alterations found, a study with a larger number of individuals would be necessary. Chronic inflammatory demyelinating polyradiculopathy affects the QoL of patients in different ways.

ANTECEDENTES: Estudos foram realizados com o objetivo de avaliar a qualidade de vida (QV) de pacientes acometidos pela polirradiculopatia desmielinizante inflamatória crônica (PDIC). No entanto, a questão cognitiva ainda é pouco abordada. OBJETIVOS: Avaliar a QV e o comprometimento cognitivo em pacientes com PDIC bem como se existe correlação entre esses parâmetros. MéTODOS: Sete pacientes com PDIC e sete controles pareados foram submetidos a: miniexame do estado mental (MEEM); avaliação cognitiva de Montreal (MoCA); teste de substituição de símbolo de dígito/cópia de símbolo (DSST); escala de gravidade da fadiga (FSS); Beck depressive inventory-I (BDI-I) e um short-form of health survey (SF-36). RESULTADOS: A média de idade dos pacientes foi de 50 anos (71,4% do sexo masculino). O MMSE e o MoCA não apresentaram diferença estatística entre os grupos. Os pacientes apresentaram resultados superiores no domínio memória do MoCA (5 vs. 2, p = 0,013). No DSST, observamos uma tendência de os pacientes serem mais lentos. Houve forte correlação negativa entre os níveis de fadiga e o domínio vitalidade (SF-36). Não houve correlação significativa entre níveis de depressão e QV. Não houve correlação entre depressão e os resultados obtidos nos testes cognitivos. Níveis elevados de depressão foram observados nos pacientes (15,28 vs. 3,42, p < 0,001). Um total de 57% apresentou fadiga intensa, 28,8% dor autorreferida, e 57,1% queixam-se de câimbras. CONCLUSãO: Não há comprometimento cognitivo nos pacientes estudados. Observamos somente uma tendência de lentificação na velocidade de processamento. Para melhor avaliar as alterações encontradas, será necessário estudo com um número maior de indivíduos. A PDIC afeta de diferentes formas o nível de QV de seus portadores.

Surgical Outcome of Cauda Equina Syndrome Secondary to Disc Herniation Presenting Late in Developing Countries.

Cauda equina syndrome (CES) is a serious neurologic state in which neurological dysfunction affects the lumbar and sacral nerve roots within the vertebral canal. The nerves of the cauda equine provide the muscles that manage the bladder, bowel and the legs and the dysfunction producing impairment of bladder, bowel or sexual function and perianal or saddle numbness. Identification of CES is not only important to neurosurgeons and spine surgeons, but also to prime care practitioners, emergency room physicians, physiotherapists and allied health care professionals concerned in management of back pain. It is a significant diagnosis from a clinical and medico-legal outlook. Early surgical decompression is endorsed by most authors to best support patient's revival and trim down long term disability. This cross sectional observational study was conducted at Shaheed Suhrawardy Medical College Hospitals, Dhaka, Bangladesh from January 2015 to January 2021 and the aim of this study was to find the predictors and the clinical outcome of cauda equina syndrome after spinal decompression with delayed presentation. Among 680 patients of degenerative disc diseases; 32 cases (4.7%) had CES, those presenting late in course of disease. Time interval between bladder and bowel dysfunction and admission to hospital varied from 2-64 days with mean delay of 15.4 days. The average follow-up was 22.6 months, ranging from 12 to 34 months. There was significant positive correlation (p<0.05) between duration taken for total recovery and delay in surgery and between delayed decompression and a poor outcome. Also there was a clear correlation between the presence of complete perineal anaesthesia and absence of anal wink as both univariate and multivariate predictors of a poor outcome. There was significant association between a slower onset of CES and a favourable outcome. There was no significant correlation found between initial motor function loss, bilateral sciatica and level of the lesions as predictors of a poor outcome.

Early Disseminated Lyme Disease: Cranial Neuropathy, Meningitis, and Polyradiculopathy.

Early disseminated Lyme disease can involve the peripheral or central nervous system, but with early diagnosis and treatment, prognosis for full recovery is excellent. The typical clinical presentations of neuroborreliosis are highlighted, and an approach to diagnosis and treatment is described.

Baastrup's Disease as a Rare Cause of Cauda Equina Syndrome: A Case Report.

CASE: "Baastrup's disease" is a relatively common anatomical condition, controversially recognized as a possible cause of back pain but frequently missed by clinicians of different specialties. We present a rare case of Baastrup's disease causing compression to the cauda equina nerves due to the formation of a large pseudotumoral epidural mass. The patient underwent a successful surgical decompression with remarkable improvement in her neurological presentation. The histopathological findings consisted of increased collagen deposition and chondroid metaplasia. CONCLUSION: Clinicians should be aware of possible cauda equina syndrome in rare cases of Baastrup's disease due to pseudotumoral mass compression in the lumbar spine.
