Allodynia in cervical polyradiculopathy due to low-voltage electrical burn injury: A case report

@#Neuropathic pain has been described following an electrical injury, whether as an immediate response or a late-onset sequela. There is much information on high-voltage injuries in literature due to its dramatic presentation, but limited studies on low-voltage injuries. However, low-voltage injuries can be as diverse and may have symptoms varying from minimal cutaneous involvement to full-thickness injury. Significant injuries may result from multiple factors, including prolonged duration of exposure and a higher amount of current transmitted. We illustrate an atypical presentation of a low-voltage injury in a 17-year-old female. The patient had a low voltage electrical injury with no cutaneous burn noted on the affected extremity. She initially presented with allodynia, which seemed disproportionate to the clinical findings expected in a low-voltage injury. The patient underwent an electrodiagnostic study, which showed cervical polyradiculopathy (C5, C6, C7 polyradiculopathy) and neuromusculoskeletal ultrasonology, which showed enlarged right C5 nerve root. Medical management, daily physical and occupational therapies, and psychological management, were instituted, which resulted in significant improvement of the patient’s pain level and functional status. We describe the importance of the multimodal approach (medical and rehabilitation) in managing this atypical case.

Sindrome de Guillain-Barre variante axonal en pediatria: reporte de caso / Guillain-Barre Syndrome axonal variant in pediatrics: case report

RESUMEN El síndrome de Guillain-Barré es una polirradiculoneuropatía inflamatoria aguda, caracterizada por debilidad simétrica de carácter progresivo, de inicio distal asociado con arreflexia y síntomas sensitivos leves. La variante NMAA es una entidad poco frecuente en América Latina. Se reporta el caso de un paciente de sexo masculino, de seis años, previamente sano, con diagnóstico de síndrome de Guillain-Barré variante axonal, secundario a cuadro de vías aéreas superiores. La importancia del reporte radica en informar al pediatra y a otros profesionales de la salud acerca de la existencia de esta entidad y así aumentar la sospecha diagnóstica, considerando su baja incidencia. Se destaca también la posibilidad de encontrar variabilidad en las formas clínicas típicas de presentación, como lo fue el caso presentado, ya que es un subtipo de la enfermedad que está clásicamente caracterizada como grave, de evolución tórpida y con frecuentes secuelas.

SUMMARY Guillain-Barre syndrome is an acute inflammatory polyradiculoneuropathy characterized by progressive symmetric weakness of distal onset associated with areflexia and mild sensory symptoms. The AMAN variant is a rare entity in Latin America. The case of a 6-year-old male patient, previously healthy, with a diagnosis of Guillain-Barre Syndrome, axonal variant, secondary to upper airway symptoms, is reported. The importance of the report lies in informing the pediatrician and other health professionals about the existence of this entity and thus increasing the diagnostic suspicion considering its low incidence. We also highlight the possibility of finding variability in the typical clinical forms of presentation, as was the case presented, since it is a subtype of the disease that is classically characterized as severe and with torpid evolution. It is also associated with frequent sequelae.

Alteraciones atípicas del líquido cefalorraquídeo en el Síndrome de Guillain-Barré: Reporte de casos / Atypical Alterations of cerebrospinal fluid in Guillain Barré Syndrome: Cases Reports

RESUMEN El síndrome de Guillain-Barré se caracteriza por presentar una disociación albúmino-citológica en la mayoría de pacientes. La presencia de pleocitosis o hipoglucorraquia puede alejar el diagnóstico, por lo que se recomienda descartar, principalmente, causas infecciosas. Se presentan tres casos cuyos estudios de líquido cefalorraquídeo mostraron pleocitosis linfocítica e hiperproteinorraquia persistente y uno de ellos, además, hipoglucorraquia; fue solamente en análisis posteriores que los tres pacientes presentaron la clásica disociación albuminocitológica. El estudio neurofisiológico en todos ellos demostró asimismo un compromiso axonal. Las alteraciones atípicas en el contexto de parálisis flácida aguda justificarían repetir el análisis de líquido cefalorraquídeo y descartar otras etiologías, pero sin posponer en modo alguno el tratamiento.

SUMMARY Guillain-Barré syndrome shows a cyto-albuminologic dissociation in most patients. Pleocytosis or hypoglycorrhachia may defer the diagnosis, a reason for which an infectious etiology must be ruled out. Three cases of Guillain-Barré are described, whose cerebrospinal fluid tests showed limphocytic pleocytosis and persistently elevated protein concentration, while one of the cases also showed hypoglycorrhachia, and the classic cyto-albuminologic dissociation was only demonstrated in subsequent analysis. The neurophysiologic evaluation revealed an axonal disruption in all the patients. The atypical alterations in the context of acute flaccid paralysis warrant a retesting of the cerebrospinal fluid in order to rule out other etiologies, but without postponing the start of treatment.

A Diffuse Leptomeningeal Glioneural Tumor Case Producing Hydrocephalus and Polyradiculopathy

The present report describes the case of a male 17-year-old patient who progressively developed a hydrocephalus and polyradiculopathy due to involvement of central nervous system (CNS) by a diffuse leptomeningeal glioneuronal tumor (DLGNT). The tumor had partial remission in response to the treatment with radiotherapy plus procarbazine, lomustine, and vincristine (PCV) chemotherapy, and the patient had improvement in function and pain levels. The current knowledge about DLGNT, including its clinical manifestations, imaging findings, histological characteristics, and treatment are revised and discussed in the present paper.

Interventional analgesic block in a dog with cauda equina syndrome. Case report / Bloqueio analgésico intervencionista em cão com síndrome da cauda equina. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: The cauda equina syndrome is a neurological condition prevalent in dogs which neurological signs are caused by the compression of the nerve roots located in the lumbosacral spinal canal and is frequently associated with pain, claudication, paresis or paralysis of the hindlimbs and changes in the functioning of the sphincters. The objective of this study was to check the effects of the epidural injection with the combination of dexamethasone, bupivacaine and morphine on the relief of pain and neurological signs in a dog with traumatic cauda equina syndrome. CASE REPORT: Case study of a 2-year old Red Heeler dog, weighing 16kg with a diagnosis of post-trauma cauda equina syndrome. The evaluation consisted of neurological and pain assessment (visual analog scale), quality of life ("5H2M") and infrared thermography. After the initial evaluation and authorization of the tutor, the dog was submitted to general anesthesia and a lumbosacral epidural block, guided by electrostimulation, with the association of dexamethasone, bupivacaine and morphine. After the procedure, the dog showed immediate remission of claudication, paresis and satisfactory analgesia on days 0, 15, 30 and 60 after the intervention. CONCLUSION: The epidural block was effective in improving pain, quality of life and neurological signs and may be an excellent alternative in dogs with pain syndromes associated with the spinal canal.

RESUMO JUSTIFICATIVA E OBJETIVOS: A síndrome da cauda equina é uma afecção neurológica prevalente em cães cujos sinais neurológicos são causados pela compressão de raízes nervosas localizadas no canal espinhal lombossacral sendo frequentemente associada à dor, claudicação, paresia ou paralisia de membros pélvicos e alterações do funcionamento dos esfíncteres. O objetivo deste estudo foi verificar os efeitos da injeção peridural com a associação de dexametasona, bupivacaína e morfina no alívio da dor e dos sinais neurológicos em um cão com síndrome da cauda equina de origem traumática. RELATO DO CASO: Estudo do caso de um animal da espécie canis familiaris, raça red heeler, fêmea, 2 anos de idade e 16kg de peso corporal com diagnóstico de síndrome da cauda equina pós-trauma. A avaliação consistiu no exame neurológico completo, avaliação de dor (escala analógica visual), de qualidade de vida ("5H2M") e por termografia infravermelha. Após a avaliação inicial e autorização do tutor, a cadela foi submetida à anestesia geral e a um bloqueio intervencionista peridural lombossacral, guiado por eletroestimulação, com a associação de dexametasona, bupivacaína e morfina. Após o procedimento, a cadela apresentou imediata remissão da claudicação, da paresia e uma satisfatória analgesia nos dias 0, 15, 30 e 60 após a intervenção. CONCLUSÃO: O bloqueio peridural intervencionista foi eficaz na melhora da dor, da qualidade de vida e dos sinais neurológicos, podendo ser uma excelente alternativa em cães com síndromes dolorosas associadas ao canal espinhal.

Does the Surgical Timing and Decompression Alone or Fusion Surgery in Lumbar Stenosis Influence Outcome in Cauda Equina Syndrome?

STUDY DESIGN: A retrospective comparative analysis of 64 patients with cauda equina syndrome (CES), who underwent either decompression alone (NF) or fusion (F) surgery. PURPOSE: We compared the outcomes and timing effects. OVERVIEW OF LITERATURE: CES can cause loss of autonomic control of vesicular function and lower limb neurological deficits. Prompt diagnosis and emergency surgery markedly improve outcome. Although decompression only is a mainstream technique, there is guarded recovery of vesicular dysfunction. Decompression ventrally in a narrow window requires manipulation of neural tissue in an already jeopardised critical canal and may accentuate irreversible damages. In F surgery, the adequate exposure leads to a lower neural manipulation. METHODS: Until January 2008, we treated CES with decompression (laminectomy and/or discectomy). However, from that month forward, all our single-level CES patients have received a fusion operation. In this study, characteristic categorical variables and outcomes were analysed. RESULTS: In a retrospective analysis of 64 patients, NF (n=37) and F (n=27) who received treatment, we found that both groups improved significantly on follow-up in all objective parameters. Although, the comparison of clinical and functional outcome data between the two groups was statistically insignificant, the average value of objective outcome such as vesicular function, low back pain (LBP), and complications was better for patients in F group compared with NF group. However, the patient satisfaction for the F group was also lower, in view of their residual symptoms and disabilities. Contrary to common perceptions, we found that the timing of surgery does not influence the recovery rate for either approach. CONCLUSIONS: Although both the techniques appear to be equally effective, the fusion approach overall showed a definite edge over non-fusion, with respect to reduced incidence of iatrogenic dural tears, LBP, and overall outcome, even despite the lower patient satisfaction.

Las manifestaciones clínicas más frecuentes fueron: parestesia (86,3%), paresia muscular (95.4%), arreflexia osteotendínea (86.3%) y dolor muscular (54.5%). 50% de los pacientes tuvo una estadía hospitalaria mayor a cuatro semanas. DISCUSIÓN: La mayoría de las características epidemiológicas y clínicas concuerdan con la literatura y estadísticas internacionales. No obstante, existen diferencias en edad de presentación y estacionalidad.

INTRODUCTION: GBS is an acute polyradiculopathy, which is often associated with a previous infection. It constitutes a neurological emergency. The classic triad is symmetric and ascending paresis, abolition or diminution of osteotendine reflexes and paresthesias. It is clinically suspected. The treatment is support, plasma exchange and intravenous immunoglobulin. The aim of this study is to describe the epidemiological and clinical characteristics of patients with a diagnosis of GBS at the Clinical Hospital Herminda Martin de Chillán between 2010 and 2015. MATERIAL AND METHODS: Retrospective descriptiv estudy of 22 patients` medical records. Inclusion criteria were to have the diagnosis of GBS reported in theclinical record and to have been seen at the HCHM duringJanuary 2010 and May 2016. Exclusion criterion is not to physically counton the patient'sclinical record. The investigated variables were age, sex, seasonality, history of previous infection, clinical manifestations and recovery time. RESULTS: Predominance of GBS in males (63,6%), in the 0-20 years range (45,4%), debuting in autumn-winter (59%) and previous infection in 54,5% of patients. The most frequent clinical manifestations were: paresthesia (86.3%), muscle paresis (95.4%), osteotendinous areflexia (86.3%) and muscle pain (54.5%). 50% of patients recovered in more than four weeks. DISCUSSION: Most of the epidemiology and clinical features are consistent with the literature and international statistics. However, there are differences in age of presentation and seasonality

Posterior Epidural Migration of a Lumbar Intervertebral Disc Fragment Resembling a Spinal Tumor: A Case Report

Posterior epidural migration of a lumbar intervertebral disc fragment (PEMLIF) is uncommon because of anatomical barriers. It is difficult to diagnose PEMLIF definitively because of its relatively rare incidence and the ambiguity of radiological findings resembling spinal tumors. This case report describes a 76-year-old man with sudden-onset weakness and pain in both legs. Electromyography revealed bilateral lumbosacral polyradiculopathy with a mass-like lesion in L2-3 dorsal epidural space on lumbosacral magnetic resonance imaging (MRI). The lesion showed peripheral rim enhancement on T1-weighted MRI with gadolinium administration. The patient underwent decompressive L2-3 central laminectomy, to remove the mass-like lesion. The excised lesion was confirmed as an intervertebral disc. The possibility of PEMLIF should be considered when rim enhancement is observed in the epidural space on MRI scans and electrodiagnostic features of polyradiculopathy with sudden symptoms of cauda equina syndrome.

The Factors That Affect Improvement of Neurogenic Bladder by Severe Lumbar Disc Herniation in Operation

OBJECTIVE: This study analyzed retrospectively the bladder function of patients after early surgery for cauda equina syndrome (CES) performed within 24 or 48 hours, or after 48 hours of the onset of autonomic symptoms. METHODS: We retrospectively reviewed the clinical data of 31 patients after decompression surgery for lumbar disc herniation (LDH) who had been diagnosed with CES between January 2001 and December 2014 at Inha University Hospital. The following factors were assessed to evaluate the influence of time to surgery: bladder function, rectal incontinence, sexual dysfunction, LDH level, and degree of spinal canal compression. RESULTS: After decompression, the outcome group was categorized into normal bladder function and abnormal bladder function. The patients operated on within 48 hours showed an improved postoperative outcome. Among 16 patients operated on within 48 hours, 13 (81%) recovered normal bladder function. In contrast, among 15 patients with decompression after 48 hours, 6 (40%) recovered normal bladder function. Among 21 patients with mild bladder dysfunction at admission, 16 (76%) recovered normal bladder function after decompression. CONCLUSION: Our study suggests that patients who have decompression surgery within 48 hours of the onset of bladder dysfunction, improve their chances of recovering bladder function than those who have a late operation (>48 hours). Also, patients with mild bladder dysfunction are more likely to recover bladder function after decompression, than patients with severe bladder dysfunction.

Clinical importance of F-waves as a prognostic factor in Guillain-Barré syndrome in children / 소아과

PURPOSE: A limited number of studies have examined the link between F-wave abnormalities and clinical presentation in pediatric Guillain-Barré syndrome (GBS). Therefore, this study examined the importance of F-wave abnormalities as a prognostic factor in pediatric GBS patients. METHODS: The records and electrodiagnostic studies (EDS) of 70 GBS patients were retrospectively evaluated, and divided into 2 groups according to the results of EDS. Group A (n=33) presented with F-wave abnormalities, and group B (n=26) exhibited normal findings. We compared laboratory reports, clinical features, response to treatment, and prognosis between the 2 groups. RESULTS: Motor weakness was the most frequently observed symptom for either group. Clinically, the incidence of fever and upper respiratory symptoms differed between the 2 groups, while the prevalence of abnormal deep tendon reflex (DTR) was significantly higher in group A than B (P<0.05). Patients diagnosed with GBS had received intravenous immunoglobulin treatment: 94% in group A and 58% in group B. Furthermore, significantly greater numbers of patients in group A showed H-reflex abnormalities and poor prognosis compared with group B (P<0.05). CONCLUSION: This study demonstrated that F-waves are a clinically important prognostic factor in GBS. F-wave abnormalities were associated with abnormal DTR and poor prognosis in patients. Limited studies have examined the link between F-wave abnormalities and clinical results; therefore, further randomized controlled studies are needed to confirm the clinical characteristics and efficacy of treatments.

Polirradiculopatía inflamatoria crónica sensitiva / Chronic inflammatory sensory polyradiculopathy

La polirradiculopatía inflamatoria crónica sensitiva es una entidad definida, frecuentemente subdiagnosticada y potencialmente tratable. Debe ser sospechada en pacientes con ataxia sensitiva, estudios de conducción nerviosa normales y una resonancia magnética que muestre engrosamiento y realce con gadolinio de las raíces lumbosacras. Presentamos el caso de un hombre de 57 años de edad con marcada ataxia sensitiva en pierna izquierda. Al examen físico presentaba fuerza conservada, reflejos osteotendinosos disminuidos, tacto fino y superficial reducidos por debajo de las rodillas; abatiestesia y apalestesia en ambos pies. Los estudios de conducción nerviosa eran normales, los potenciales evocados somatosensitivos tibiales con ausencia de respuesta bilateral. El líquido cefalorraquídeo presentaba hiperproteinorraquia sin células. La resonancia magnética mostró engrosamiento y realce con gadolinio de las raíces lumbosacras. El paciente fue tratado con inmunoglobulina endovenosa (IgEV) a 2 g/kg durante 5 días, con buena respuesta. La evolución clínica, la hiperproteinorraquia, el realce de raíces en la resonancia magnética, la buena respuesta a la inmunoterapia y la exclusión de otras causas de ataxia sensitiva fueron compatibles con el diagnóstico de polirradiculopatía inflamatoria crónica sensitiva. Para el diagnóstico de esta enfermedad se requiere la identificación del compromiso aislado de las raíces sensitivas.

Chronic inflammatory sensory polyradiculopathy is a defined entity, frequently underdiagnosed, and potentially treatable. It must be suspected in patients with sensory ataxia, normal nerve conduction studies, and MRI with thickened lumbosacral nerve roots and gadolinium enhancement. We present the case of a 57-year-old man with marked sensory ataxia on his left leg. Examination showed normal strength, decreased knee and ankle jerks. Light touch and pinprick sensations were reduced below the knees. Vibration and joint position sense were absent at the feet. Nerve conduction studies were normal. Tibial sensory evoked potentials disclosed absent responses bilaterally. CSF was acellular with elevated protein. Lumbosacral magnetic resonance showed thickening of roots, with gadolinium enhancement. The patient was treated with IV-Ig, 2 g/kg, for 5 days with improvement of symptoms. The clinical course, elevated CSF protein, the evidence of root enhancement on the MRI, good response to immunotherapy, and the exclusion of other causes of sensory ataxia, were compatible with the diagnosis of chronic inflammatory sensory polyradiculopathy. To diagnose this disease the identification of isolated involvement of the sensory roots is required.

Atypical Guillain-Barre Syndrome Misdiagnosed as Lumbar Spinal Stenosis

Guillain-Barre syndrome (GBS) is an acute inflammatory demyelinating polyneuropathy. In typical cases, the first symptoms of GBS are pain, numbness, paresthesia, weakness in the limbs. Autonomic involvement is common and causes urinary retention and ileus. Much of these symptoms overlap with those of lumbar spinal stenosis. Therefore, correct diagnosis of GBS in a patient with symptomatic lumbar spinal stenosis or in a patient with atypical manifestations of GBS can be difficult, especially early in the course of GBS. Here, we report on a case of atypical GBS in a 74-year-old previously healthy patient with lumbar spinal stenosis and discuss the differential diagnosis of the GBS and lumbar spinal stenosis.

Malignancy-associated dermatomyositis with polyradiculoneuropathy:a case report with literature review / 中华风湿病学杂志

Objective To investigate the difference and treatment strategy of malignancy-associated dermatomyositis and other para-neoplastic neurological syndromes (PNS).Methods The clinical characteristics of a patient with malignancy-associated dermatomyositis and poly radiculoneuropathy was reported and the relevant literature was reviewed.Results Patients with dermatomyositis had increased risk of malignancies,and should routinely screened.Dermatomyositis and polyradiculoneuropathy was clinically similar,but could rarely be seen in the same malignant patient.Malignancy -associated dermatomyositis and PNS had similar pathogenesis.The treatment strategy of both was similar.Malignancy specific treatment should be initiated and immune suppressive agents should be prescribed concurrently.Conclusion Rheumatolgists should aware the association between dermatomyositis and potential underlying malignancies.Multiple para-neoplastic syndromes could be seen in the same patient,but the diagnosis should be considered as one.

Neurologic cytomegalovirus complications in patients with AIDS: retrospective review of 13 cases and review of the literature / Complicações neurológicas causadas pelo citomegalovírus em pacientes com AIDS: estudo retrospectivo de 13 casos e revisão da literatura

Neurological disorders caused by Cytomegalovirus (CMV) in patients with Acquired Immunodeficiency Syndrome (AIDS) are rarely reported in the Highly Active Antiretroviral Therapy (HAART) period. The objective of this study was to describe the main clinical and laboratory features of patients with CMV-related neurological complications in HIV-infected patients admitted to a referral center in São Paulo, Brazil. CMV disease requires the identification of the virus in the cerebrospinal fluid (CSF) using Polymerase Chain Reaction (PCR). Thirteen cases were identified between January, 2004 and December, 2008. The median age of patients was 38 years and nine (69 percent) were men. At admission all patients were aware of their HIV status and only four (31 percent) patients were on HAART. Patients who were not on antiretroviral therapy before admission received HAART while inpatients. CMV disease was the first AIDS-defining illness in eight (62 percent) patients. The neurologic syndromes identified were diffuse encephalitis (n = 7; 62 percent), polyradiculopathy (n = 7; 54 percent), focal encephalitis (rhombencephalitis) (n = 1; 8 percent), and ventriculo-encephalitis (n = 1; 8 percent). Seven (54 percent) patients presented extra-neural CMV disease and four (31 percent) had retinitis. The median of CD4+ T-cell count was 13 cells/µL (range: 1-124 cells/µL). Overall in-hospital mortality was 38 percent. Eight patients used ganciclovir or foscarnet (in-hospital mortality: 50 percent) and five patients used ganciclovir and foscarnet (in-hospital mortality: 20 percent). None of the patients fulfilled the diagnosis criteria of immune reconstitution inflammatory syndrome. Four patients were lost to follow-up, and three patients presented immune recovery and discontinued secondary prophylaxis. Although infrequent, distinct neurological syndromes caused by CMV continue to cause high mortality among AIDS patients. Survival depends upon the use of effective antiviral therapy against CMV and the early introduction of HAART.

As complicações neurológicas causadas pelo Citomegalovírus (CMV) em pacientes com aids são raramente relatadas na era HAART. O objetivo deste estudo foi descrever as principais características clínicas e laboratoriais de pacientes com complicações neurológicas associadas ao CMV em pacientes com aids admitidos em centro de referência em Sao Paulo, Brasil. A doença citomegálica precisou da identificação do vírus no líquor mediante a reação em cadeia da polimerase (PCR). Treze casos foram identificados entre janeiro de 2004 e dezembro de 2008. A mediana da idade foi 38 anos e nove (69 por cento) eram homens. Na admissão, todos os pacientes sabiam do seu status sorológico para o HIV e apenas quatro (31 por cento) pacientes usavam HAART. A doença citomegálica foi a primeira doença definidora de aids em oito (62 por cento) pacientes. As síndromes neurológicas identificadas foram: encefalite difusa (n = 7; 62 por cento), polirradiculopatia (n = 7; 54 por cento), encefalite focal (romboencefalite) (n = 1; 8 por cento), e ventrículo-encefalite (n = 1; 8 por cento). Sete (54 por cento) pacientes apresentaram doença citomegálica fora do sistema nervoso e quatro (31 por cento) tiveram retinite. A mediana da contagem de células CD4+ foi 13 células/µL. A mortalidade global durante a internação foi 38 por cento. Oito pacientes usaram ganciclovir ou foscarnet (mortalidade: 50 por cento) e cinco pacientes usaram ganciclovir e foscarnet (mortalidade: 20 por cento). Nenhum paciente apresentou critérios diagnósticos da síndrome inflamatória de reconstituição imunológica. Quatro pacientes foram perdidos do acompanhamento ambulatorial e três pacientes apresentaram reconstituição imunológica e descontinuaram as profilaxias secundárias. Embora raras, as particulares síndromes neurológicas causadas pelo CMV continuam causando elevada mortalidade em pacientes com aids. A sobrevida depende do uso de terapia antiviral efetiva contra o CMV e a introdução oportuna do HAART.

Open Reduction without Fusion of Bilateral Jumped Lumbosacral Facet Dislocation Associated with Symphysis Pubis Separation and Cauda Equina Syndrome: Case Report

This paper reports a rare case of a lumbosacral dislocation associated with symphysis pubis separation and cauda equina syndrome. A 39-year-old male who diagnosed traumatic lumbosacral dislocation underwent an open reduction without fusion. After an open reduction and internal fixation of a symphysis pubis separation, a missed lumbosacral dislocation was diagnosed and an open reduction was performed without fusion. Due to the symphysis pubis separation, the patient was not allowed weight bearing for 3 months, which then began from wheel chair ambulation. At the 6-month follow up evaluation, there was no back pain but the patient reported mild S1 nerve root sensory symptoms. Lumbosacral dislocation is common in high energy polytrauma patients and can be misdiagnosed. However, prompt reduction without fusion is a good alternative treatment.

Unilateral Abdominal Protrusion Developed in Diabetic Patient after Postherpetic Neuralgia / 대한통증학회지

There are many causes of chronic abdominal pain and abdominal protrusion. But, they are likely to be confused with diabetic thoracic polyradiculopathy. Differentiation between this self-limiting complication and abdominal herniation is important to avoid unnecessary procedure. We describe the case of 77-years-old man with 10 years history of non-insulin dependent diabetes mellitus, who was suffering from postherpetic neuralgia for 10 months and presented with a abdominal segmental paresis and protrusion. The paraspinal electromyography showed bilateral lower thoracic radiculopathy.

Chronic Left Upper Quadrant Abdominal Pain Diagnosed as Diabetic Thoracic Polyradiculopathy: A case report

Diabetic thoracic polyradiculopathy is an unusual cause of severe, chronic abdominal pain in patient with diabetes mellitus of variable duration. The diagnosis can be made by careful history taking, physical examination and paraspinal and abdominal muscle electromyography. Since there are so many diseases that cause similar abdominal pain, it is hard to diagnose diabetic thoracic polyradiculopathy. A 41-year-old female patient with diabetes mellitus had been taken to the department of internal medicine due to unexplained chronic left upper quadrant abdominal pain. Upper gastrointestinal endoscopy, abdominal computed tomography, urologic and gynecologic examinations had been done but failed to find the cause of abdominal pain. We diagnosed chronic abdominal pain of the patient as diabetic thoracic polyradiculopathy confirmed by electromyography and report this case with a brief review of the related literatures.

A Case of Cytomegalovirus Lumbosacral Polyradiculopathy in Acquired Immune Deficiency Syndrome

BACKGROUND AND SIGNIFICANCE: Cytomegalovirus(CMV) is the most common opportunistic viral agent encountered in AIDS and its relation to peripheral neuropathy and rapidly developing lumbosacral polyradiculopathy has been well documentated. CASE: A 30-year-old man with acquired immune deficiency syndrome presented with rapidly progressive paraplegia and voiding difficulty. Electrophysiologic studies revealed a lumbosacral polyradiculopathy with loss of bulbocavernous reflex and CSF examination showed polymorphonuclear pleocytosis with elevated protein level. Also, spinal T1-weighted MRI with gadolinium-DTPA showed enhancement of the pial lining of the conus medullaris, cauda equina, and lumbar nerve roots. Anti CMV titers were elevated in CSF and culture for CMV in both blood and urine was positive. The patient was treated with ganciclovir. CONCLUSION: We report a case of polyradiculopathy related to CMV in a patient with acquired immune deficiency syndrome(AIDS). It seems to be important to differentiate this unique syndrome from other causes of rapidly developing paraplegia syndromes among AIDS patients.
