ABSTRACT

ABSTRACT BACKGROUND: Hepatoportal sclerosis HPS or obliterative portal venopathy (OPV), one of the differential diagnoses for non-cirrohtic portal hypertension, is characterized by the disappearance of the portal branches, portal and septal fibrosis, perisinusoidal fibrosis and regenerative nodular hyperplasia (RNH). It is a spectral disease that may progress to severe portal hypertension. Its etiopathogenesis is still little understood, especially in Brazil, it has been probably misdiagnosed due to its histopatological similarities with the hepatosplenic form of schistosomiasis. OBJECTIVE: To analyze the profile of patients with HPS in Northeastern Brazil and to demonstrate the pathological characteristics of HPS. METHODS: We retrospectively analyzed cases of OPV in liver biopsies and explants from a referral center for liver in Bahia - Brazil. The qualitative and quantitative analysis of the portal tracts and liver parenchyma was made so that comparisons could be done among the HPS findings of our population and the findings described by other authors. RESULTS: From the 62 patients identified with HPS, 42% were male, while 58% were female. The average age at diagnosis was 48.3 years. From this group, we analyzed the liver biopsy of 10 patients whose diagnosis of schistosomiasis could be ruled out. From these 100% (10/10) presented dense portal fibrosis and portal venous obliteration. Liver parenchymal atrophy was present in 60% (6/10) of the patients, sinusoidal dilation was present in 30% (3/10), the presence of portal septa occurred in 50% (5/10) and dense portal fibrosis in all patients analyzed. Nodular regenerative hyperplasia was found in 30% (3/10) of the patients. CONCLUSION: HPS seems to be neglected and misdiagnosed in Brazil, due to its similarities with schistossomiasis. In our study dense portal fibrosis, obliteration of the portal vein branches, parenchymal atrophy, sinusoidal dilatation and parenchymal nodular hyperplasia were the main histopathological findings and were similar to that described in other countries.


RESUMO CONTEXTO: Esclerose hepatoportal EHP ou venopatia portal obliterativa VPO, um dos diagnósticos diferenciais para a hipertensão portal não cirrótica, é caracterizada pelo desaparecimento dos ramos portais, fibrose portal e septal, fibrose sinusoidal e hiperplasia nodular regenerativa HNR. A EHP é um doença espectral, que pode progredir para hipertensão portal severa. Sua etiopatologia é ainda pouco compreendida, especialmente no Brasil, onde ela é provavelmente subdiagnoticada devido as suas similaridades com a forma hepatoesplênica da esquistossomose. OBJETIVO: Analizar o perfil dos pacientes com EHP no Nordeste do Brasil, e demontrar as características patológicas da EHP. MÉTODOS: Analisamos restrospectivamente os casos de VPO em biópsias hepáticas e explantes de um centro de referência em fígado na Bahia, Brasil. A análise qualiquantitativa dos tratos portais e parênquima hepático foi realizada, permitindo a comparação entre os nossos paciente e os achados descritos por outros autores. RESULTADOS: Entre os 62 paciente identificados com EHP, 42% era do sexo masculino, 58% era do sexo feminino. A média de idade no diagnótico foi 48,3 anos. Desse grupo, analizamos a biópsia hepática de 10 pacientes nos quais o diagnóstico de esquistossomose pode ser excluído. Desses pacientes, 100% 10/10 se apresentou com fibrose portal densa e obliteração venosa portal. Atrofia do perênquima hepático estava presente em 60% 6/10 dos pacientes, dilatação sinusiodal em 30% 3/10 a presença de septos portais ocorreu em 50% 5/10 e fibrose portal densa foi achada em todos os pacientes. Hiperplasia nodular regenerativa foi encontrada em 30% dos pacientes. CONCLUSÃO: A EHP parece ser negligenciada e subdiagnosticada no Brasil, devido as suas similaridades com esquistossomose. Em nosso estudo, fibrose portal densa, obliteração dos ramos da veia porta, atrofia do parênquima, dilatação sinusoidal e hiperplasia nodular do parênquima foram os principais achados histopatológicos e foram semelhantes aos descritos em outros países.

ABSTRACT

El síndrome de la piel indurada es un trastorno esclerosante crónico, infrecuente, que se presenta en la infancia, caracterizado por la induración progresiva de la piel. Esta afección puede provocar restricciones torácicas y dificultad respiratoria, limitaciones en la movilidad articular y trastornos en la marcha, con importante deterioro de la calidad de vida. Debido a que sus opciones terapéuticas son escasas y poco eficaces, es fundamental que el paciente inicie precozmente una terapia física para prevenir estas complicaciones y que se continúe estudiando esta enfermedad a fin de poder ofrecer a los pacientes más y mejores tratamientos. Se presenta el caso de una paciente de 9 años con síndrome de la piel indurada y su desafío terapéutico.


Stiff skin syndrome is a chronic, rare sclerosing disorder that occurs in childhood, characterized by progressive induration of the skin that can cause thoracic restrictions and respiratory distress, limitations in joint mobility and gait difficulties, with significant deterioration of the quality of life. Because their therapeutic options are scarce and ineffective it is essential to start an early physical therapy to prevent these complications and to continue studying this condition to be able to offer patients more and better treatments. We present the case of a 9-year-old patient with indurated skin syndrome and its therapeutic challenge.

ABSTRACT

Dans le cadre d'une exploration radiographique de routine au niveau des maxillaires ou lors d'un bilan orthodontique, il est fort probable de découvrir fortuitement chez l'adolescent des zones d'ostéosclérose asymptomatiques, qui se situent le plus souvent à proximité des apex des dents avoisinantes. Ces zones d'ostéosclérose se présentent sous la forme de foyers radio-opaques localisés et clairement délimités, à croissance non expansive et de forme elliptique ou irrégulière. Parmi ces lésions radio-opaques, on note l'ostéite condensante focale qui est associée à des processus pathologiques inflammatoires ou infectieux, souvent en regard des apex des molaires permanentes mandibulaires. L'objectif de notre travail est de mettre le point sur cette entité pathologique afin d'aider le praticien à l'identifier et à la différencier des autres lésions radio-opaques des maxillaires, ainsi que de pouvoir réaliser une prise en charge précoce et correcte de cette lésion

ABSTRACT

Encapsulating peritoneal sclerosis (EPS) is a rare but severe complication of peritoneal dialysis. A total of 50% of the patients died within 12 months after being diagnosed. There are no obvious clinical symptoms in the early stage of EPS, which is easy to be missed. And there are few case reports of EPS in early stage. On December 22, 2018, a 70-year-old male patient undergoing peritoneal dialysis for 17 months, who was diagnosed as EPS, was admitted to the Department of Nephrology, the Third Xiangya Hospital, Central South University. The patient's peritoneal dialysis catheter was obstructed after peritonitis. The peritoneal dialysis fluid couldn't be drain in and out of the abdominal cavity. Therefore, the laparoscopy was performed to repair the catheter. The operation in progress showed that the peritoneum was slightly thickened and the ileocecal intestinal tube was closely adhered to the parietal peritoneum where the catheter was wrapped, indicating the early stage of EPS. Peritoneal relaxation was performed. The patient's catheter was normal after adhesiolysis. He underwent hemodialysis, nutritional supporting as well as peritoneal dialysis transition, etc. The peritonitis was controlled after 10 days and the peritoneal dialysis was resumed. After discharge from hospital, the patient took moxifloxacin for 2 more weeks. We followed up the patient for 6 months. The automated peritoneal dialysis is maintained, and everything remains normal. Clinicians need to improve understanding of EPS. Early diagnosis and laparoscopic adhesiolysis is helpful to continue peritoneal dialysis treatment.

ABSTRACT

This study aimed to investigate the effect of a caregiver intensive education program (CIEP) on anxiety, depression, and quality of life (QOL) in patients with drug-resistant temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS) who underwent cortico-amygdalohippocampectomy (CAH). Ninety patients with drug-resistant TLE-MTS who underwent CAH and their caregivers were recruited and randomly allocated to the CIEP group or control group as 1:1 ratio. Caregivers received the CIEP program or routine guidance/education (control group). Anxiety/depression and QOL in patients at month (M)0, M1, M3, and M6 were assessed by the Hospital Anxiety and Depression Scale (HADS) scale and the QOL in Epilepsy Inventory-31 (QOLIE-31), respectively. Treatment efficacy at M6 was assessed by Engel classification. The HADS-anxiety score at M3 (P=0.049) and M6 (P=0.028), HADS-anxiety score change (M6-M0) (P=0.001), percentage of anxiety patients at M6 (P=0.025), and anxiety severity at M6 (P=0.011) were all decreased in the CIEP group compared with the control group. The HADS-depression score at M6 (P=0.033) and HADS-depression score change (M6-M0) (P=0.022) were reduced, while percentage of depression patients at M6 (P=0.099) and depression severity at M6 (P=0.553) showed no difference in the CIEP group compared with the control group. The QOLIE-31 score at M6 (P=0.043) and QOLIE-31 score change (M6-M0) (P=0.010) were both elevated in the CIEP group compared with the control group. In conclusion, CIEP for caregivers contributed to the recovery of anxiety and depression as well as the improvement of QOL in patients with drug-resistant TLE-MTS who underwent CAH.

ABSTRACT

Resumen Introducción: Existen dos tipos de peritonitis esclerosante (PE): primaria o idiopática y secundaria, generalmente a diálisis peritoneal (DP), y con menor frecuencia a otras patologías abdominales o sistémicas. Su mortalidad es alta. Objetivo: Comparar las características clínicas, estudios diagnósticos y tratamiento de pacientes con Peritonitis Esclerosante Primaria y Secundaria, definir si existen diferencias y determinar los principales elementos clínicos e imagenológicos que permitan hacer un diagnóstico precoz y mejorar los resultados terapéuticos. Material y Métodos: Se analizan 18 casos de PE diagnosticados en nuestro hospital, entre los años 2001-2014. Incluye una serie retrospectiva de 15 casos de PE secundaria (13 por diálisis peritoneal y 2 por cirrosis hepática). Se compara con un estudio prospectivo que incluye 3 pacientes con PE primaria. Resultados: Las principales diferencias se evidencian en la presentación clínica: PE primaria: se presenta con cuadro de obstrucción intestinal y baja de peso de distinta magnitud. PE secundaria: predominan el dolor abdominal, peritonitis recurrente y la falla de ultrafiltración. La tomografía computada de abdomen es útil, sobre todo cuando hay obstrucción intestinal. Ha hecho posible el diagnóstico preoperatorio. Conclusiones: Se requiere un alto índice de sospecha para el diagnóstico precoz de PE, sobre todo para la forma primaria. Debe sospecharse en todo paciente con dolor abdominal, vómitos recurrentes y baja de peso de cualquier magnitud; y en aquellos en diálisis peritoneal durante 5 años o más, que presenten dolor abdominal y/o peritonitis recurrente y/o falla de ultrafiltración.


Introduction: There are two types of sclerosing peritonitis (SP): primary or idiopathic and secondary, generally to peritoneal dialysis, and less frequently, to other abdominal or systemic pathologies. Mortality related to this is high. Objective: To compare the clinical feature, diagnostic studies and treatment of patients with Primary and Secondary Sclerosing Peritonitis, to define whether there are any differences and to establish the main clinical and imaging elements allowing for an early diagnosis and improving the therapeutic results. Material and Methods: An analysis of 18 SP cases diagnosed at our hospital between 2001-2014 was carried out. This includes a retrospective series of 15 cases of secondary SP (13 to peritoneal dialysis and 2 to liver cirrhosis). This is compared against a prospective study that includes 3 patients with primary SP. Results: The main differences became evident in the clinical presentation: Primary SP: occurs in an intestinal obstruction and a loss of weight scenario of varying degrees. Secondary SP: abdominal pain and recurrent peritonitis as well as ultrafiltration failure prevail. CT of the abdomen has proven to be useful, in particular in those cases where there is intestinal obstruction. It has made preoperative diagnostic possible. Conclusions: A high degree of suspicion is required for an SP early diagnosis, especially for the primary form. All patients presenting abdominal pain, recurrent vomiting and any degree of weight loss and those with five or more years of peritoneal dialysis presenting abdominal pain and/or recurrent peritonitis and/or ultrafiltration failure should raise a diagnosis suspicion.

Objetivo: Apresentar caso de calcinose em região inguinal e sua evolução cirúrgica. Relato de Caso: Paciente feminina portadora de calcinoses em região inguinal bilateral, apresentando algia moderada/grave com falha de tratamento clínico. Realizada ressecção cirúrgica das calcinoses, que formavam cordões de fibrose com aderência na fáscia do músculo oblíquo externo. Realizado fechamento primário com nylon 2.0 pontos simples subdérmicos e ponto intradérmico continuo nylon 3.0 para fechamento estético e menor reação inflamatória. Boa evolução pós- operatório. Conclusão: O melhor tratamento da calcinoses ainda não é claro. O tratamento das complicações se torna essencial para reduzir a morbidade e aumentar a qualidade de vida do paciente.


Introduction: Systemic sclerosis is a rare, autoimmune, progressive disease that affects connective tissues and internal organs by inflammation, which can cause calcinosis cutis. It can progress to painful and disabling conditions, and can become infected, especially when skin ulceration is present. Objective: To present a case of calcinosis in the inguinal region and its surgical recovery. Case Report: A female patient with calcinosis in the bilateral inguinal region presenting with moderate/severe pain had a failed clinical treatment. We performed surgical resection of the calcinosis cutis, which had formed clusters of fibrosis with adhesion to the fascia of the external oblique muscle. We used simple nylon 2.0 sutures along the subdermal plane to perform primary closure and continuous nylon 3.0 sutures along the intradermal plane for aesthetic closure and minimal inflammatory reaction. Her postoperative recovery was positive. Conclusion: The best treatment for calcinosis cutis is still unclear. Treating complications becomes essential for reducing patients' morbidity and increasing their quality of life.

ABSTRACT

Abstract Sclerosing mediastinitis (SM), previously named chronic fibrosing mediastinitis, is an inflammatory process that in its end-stage results to sclerosis around the mediastinal structures. SM is quite rare and has been correlated with inflammatory and autoimmune diseases, as well as malignancy. SM may either present in a mild form, with minor symptoms and a benign course or in a more aggressive form with severe pulmonary hypertension and subsequent higher morbidity and mortality. The diagnosis of SM may be difficult and quite challenging, as symptoms depend on the mediastinal structure that is mainly involved; quite often the superior vena cava. However, practically any mediastinal structure may be involved by the fibrotic process, such as the central airways, as well as the pulmonary arteries and veins, leading to obstruction or total occlusion. The latter may be impossible to undergo proper surgical excision of the lesion, and is considered to be a real challenge to the surgeon. We herein report a case of SM that presented with arterial and venous compression. The imaging appearance was that of unilateral pulmonary edema, associated with lung collapse. The case is supplemented by a non-systematic review of the relevant literature.

ABSTRACT

Nous rapportons le cas d'une fille gabonaise, âgé de 12 ans, sans antécédent particulier, ayant présenté une sclérose mésio-temporale droite dans les suites de crise épileptique plusieurs épisodes non contrôlées par les antiépileptiques. Cas clinique : Hospitalisée en neurologie au centre hospitalier universitaire(CHU) de Libreville, pour crise épileptique partielle à type de mouvements stéréotypés et répétitifs de mâchonnements et parfois de crise tonicoclonique généralisée, avec morsure latérale de la langue, perte d'urine et amnésie postcritique. L'imagerie par résonance magnétique(IRM) cérébrale en coupe coronale était constituée d'un hypersignal en T2 et T2 FLAIR de la région hippocampique droite témoignant une sclérose mésio-temporale droite. L'électro-encéphalogramme(EEG) était constitué de grapho éléments en fronto-pariétale bilatérale et en temporale droite. Le diagnostic d'épilepsie sur sclérose mésio-temporale était retenu en tenant compte d'un faisceau d'arguments cliniques et paracliniques. Mise sous Lamotrigine et phénobarbital après trois (3) semaines de traitement, l'évolution était stationnaire marquée par la persistance des crises épileptiques. Conclusion : La sclérose mésio-temporale est une cause sous-estimée d'épilepsie temporale chez l'enfant. Notre observation souligne le fait qu'elle est rare dans les hospitalisations de neurologie et qu'il s'agit d'une épilepsie pharmaco-résistante

ABSTRACT

Epilepsy surgery that eliminates the epileptogenic focus or disconnects the epileptic network has the potential to significantly improve seizure control in patients with medically intractable epilepsy. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) has been an established option for epilepsy surgery since the US Food and Drug Administration cleared the use of MRgLITT in neurosurgery in 2007. MRgLITT is an ablative stereotactic procedure utilizing heat that is converted from laser energy, and the temperature of the tissue is monitored in real-time by MR thermography. Real-time quantitative thermal monitoring enables titration of laser energy for cellular injury, and it also estimates the extent of tissue damage. MRgLITT is applicable for lesion ablation in cases that the epileptogenic foci are localized and/or deep-seated such as in the mesial temporal lobe epilepsy and hypothalamic hamartoma. Seizure-free outcomes after MRgLITT are comparable to those of open surgery in well-selected patients such as those with mesial temporal sclerosis. Particularly in patients with hypothalamic hamartoma. In addition, MRgLITT can also be applied to ablate multiple discrete lesions of focal cortical dysplasia and tuberous sclerosis complex without the need for multiple craniotomies, as well as disconnection surgery such as corpus callosotomy. Careful planning of the target, the optimal trajectory of the laser probe, and the appropriate parameters for energy delivery are paramount to improve the seizure outcome and to reduce the complication caused by the thermal damage to the surrounding critical structures.

ABSTRACT

STUDY DESIGN: Retrospective study.OBJECTIVES: To compare the degeneration of sacroiliac joint (SIJ) following lumbar or lumbosacral fusion.SUMMARY OF LITERATURE REVIEW: The SIJ is adjacent to lumbosacral junction and its degeneration can be the potential cause of pain. However, the study addressing SIJ degeneration following lumbar or lumbosacral fusion is very limited.MATERIALS AND METHODS: From June 2002 to June 2012, 98 patients who underwent posterior decompression and posterolateral fusion were included in this study. The study group was divided into 2 groups according to the range of fusion. Group A had fusion to L5 and included 34 patients. Group B had fusion to S1 and included 64 patients. We evaluated the five years postoperative radiologic and clinical outcomes retrospectively.RESULTS: There was no statistically significant difference of bilateral preoperative subchondral sclerosis and osteophytes of the SIJ between group A and group B. However, group B revealed statistically significant subchondral sclerosis and osteophyte formation of the SIJ than group A on every radiographs after postoperative 1 year. In group B, the number of fusion segments and age were statistically positively correlated with the degeneration of the SIJ.CONCLUSIONS: Degeneration of the SIJ revealed more rapid and more severe progression in lumbosacral fusion group than in lumbar fusion group. The number of fusion segments and age were positively correlated with the degeneration of the SIJ in lumbosacral fusion group. Therefore, these facts should be taken into account when performing spinal fusion.

ABSTRACT

PURPOSE: This study was performed to analyze the clinical and imaging features of contemporary osteomyelitis (OM) and to investigate differences in these features on panoramic radiography according to patients' history of use of medication affecting bone metabolism.MATERIALS AND METHODS: The records of 364 patients (241 female and 123 male, average age 66.8±14.9 years) with OM were retrospectively reviewed. Panoramic imaging features were analyzed and compared between patients with medication-related OM (m-OM) and those with conventional, medication-unrelated OM (c-OM).RESULTS: The age of onset of OM tended to be high, with the largest number of patients experiencing onset in their 70s. The 2 most frequent presumed causes were antiresorptive medication use (44.2%) and odontogenic origin (34.6%). On panoramic radiographs, a mix of osteolysis and sclerosis was the most common lesion pattern observed (68.6%). Sequestrum, extraction socket, and periosteal new bone formation were found in 143 (42.1%), 79 (23.2%), and 24 (7.1%) cases, respectively. The m-OM group exhibited sequestrum and extraction socket more frequently and displayed significantly higher mandibular cortical index values than the c-OM group.CONCLUSION: We observed some differences in imaging features as shown on panoramic radiography according to the history of antiresorptive medication use. This study may help elucidate the predictive imaging features of medication-related osteonecrosis of the jaw.

ABSTRACT

A 61-year-old man presented with a 3-year history of erythematous firm nodules on the hands and feet. Histopathological findings of the lesional skin revealed perivascular and diffuse neutrophilic infiltrations on the upper and mid-dermis. Increased and dilated blood vessels were observed in the upper dermis. Fibrinoid necrosis of the vessel walls was unremarkable, but endothelial swelling and scant red blood cell (RBC) extravasation were noted. Fibrosis and sclerosis of collagen fibers were noted on the deep dermis. Results of laboratory examinations, including complete blood count (CBC), routine chemistry, c-reactive protein (CRP), syphilis and human immunodeficiency virus (HIV) tests, and serum immunoglobulin electrophoresis, were all negative or within normal limit. A diagnosis of erythema elevatum diutinum was made based on the clinical and histological findings. The patient was treated with prednisolone, dapsone, colchicine, and intralesional injection of triamcinolone and showed slight improvement after treatment for 8 months.

ABSTRACT

BACKGROUND: Classical Hodgkin lymphoma (cHL) is a clinicopathologically unique, aggressive lymphoma arising from germinal center B-cells and is one of the most curable hematological malignancies. This study aimed to determine the clinical course, treatment regimens, response rates, and survival data of patients diagnosed with cHL in a tertiary center. METHODS: A retrospective review was conducted to include patients with a diagnosis of cHL from 2013 to 2017. Data of demographic and clinical characteristics, treatment regimens, and outcomes were collected and analyzed. RESULTS: We recruited 94 patients with a median age of 27.0 [interquartile range (IQR), 12] years. Most of the patients were male (61.7%) and 73.4% were ethnic Malay. Nodular sclerosis was the most common histology (77.6%), followed by mixed cellularity (6.4%) and others (16%). The median follow-up time was 28.0 (IQR, 32) months. All patients received chemotherapy but only 13.8% received radiotherapy as consolidation. The doxorubicin-bleomycin-vinblastine-dacarbazine regimen was the most common (85.1%), followed by the escalated bleomycin-etoposide-doxorubicin-cyclophosphamide-vincristineprednisolone-procarbazine regimen (14.9%). Following treatment, 76.1% of patients achieved complete response. The 2-year overall survival (OS) and progression-free survival (PFS) of the entire cohort were 96.5% and 71.1%, respectively. The 2-year OS and PFS for advanced-stage disease were 93.9% and 62.8%, compared to 100% and 82.7% for early-stage disease, respectively (P=0.252 and P=0.052, respectively). CONCLUSION: This study provides insight into the clinical presentation and treatment outcomes among patients with cHL in Malaysia. A longer study duration is required to identify OS and PFS benefits and treatment-related complications for different chemotherapeutic regimens.

ABSTRACT

PURPOSE: We report a case of postoperative endophthalmitis in the cataract patient, associated with removal of an intralenticular foreign body that had remained in place without symptoms for 20 years. CASE SUMMARY: A 45-year-old male visited our outpatient clinic complaining of gradual visual loss in his right eye over the past 3 months. In slit-lamp examinations, anterior capsular opacification, nuclear sclerosis, and posterior subcapsular opacity were observed in the right eye. Twenty years before, a tiny metallic projectile had hit his right eye, but slit-lamp examination at the time of injury did not reveal any intraocular foreign body. We decided to undergo cataract surgery. During phacoemulsification, a metallic foreign body was found in the lens and safely removed; then an intraocular lens was implanted. As hypopyon was evident 3 days later, we injected intravitreal antibiotics and applied fortified antibiotic eye drops to the right eye. The anterior chamber inflammation improved and the best-corrected visual acuity recovered to 1.0. CONCLUSIONS: Surgeon should be aware of that endophthalmitis could develop after cataract surgery with removal of an intralenticular foreign body that had been in place for 20 years.

ABSTRACT

Sclerosing mesenteritis is a rare benign disease with a prevalence of 0.16–3.4% and is characterized by chronic nonspecific inflammation and extensive fibrosis in the adipose tissue of the mesentery although the exact pathogenesis is still elusive. A 65-year-old woman was referred with suspicion of an abdominal mass and biliary stones on abdominal ultrasonography and CT. Bile duct stones were confirmed by endoscopic ultrasonography and successfully treated by endoscopic retrograde cholangiography with stone removal. Furthermore, a 4.7 cm conglomerated mass on small intestinal mesentery was suspected as sclerosing mesenteritis based on the features on abdominal MRI. However, because it could not be differentiated from malignancy without histologic examination, laparoscopic excisional biopsy was performed; it showed only inflammatory cells with extensive fibrosis. Therefore, the abdominal mass was confirmed as sclerosing fibrosis and the patient was followed-up without any treatments because no mass-related symptoms accompanied the findings. Six months later, abdominal CT showed no significant change in the mass. Herein, we report a rare case of incidentally found idiopathic sclerosing mesenteritis.

ABSTRACT

ABSTRACT Neurocysticercosis is one of the most common risk factors for epilepsy but its association with drug-resistant epilepsy remains uncertain. Conjectures of an association with drug-resistant epilepsy have been fueled by reports of an association between calcific neurocysticercosis lesions (CNL) and hippocampal sclerosis (HS) from specialized epilepsy centers in Taenia solium-endemic regions. The debate arising from these reports is whether the association is causal. Evidence for the association is not high quality but sufficiently persuasive to merit further investigation with longitudinal imaging studies in population-based samples from geographically-diverse regions. The other controversial point is the choice of a surgical approach for drug-resistant epilepsy associated with CNL-HS. Three approaches have been described: standard anteromesial temporal lobectomy, lesionectomy involving a CNL alone and lesionectomy with anteromesial temporal lobectomy (for dual pathology); reports of the latter two approaches are limited. Presurgical evaluation should consider possibilities of delineating the epileptogenic zone/s in accordance with all three approaches.


RESUMO A neurocisticercose é um dos mais comuns fatores de risco para a epilepsia, mas sua associação com a epilepsia resistente a medicamentos (DRE) permanece incerta. Conjecturas de uma associação com a DRE têm sido alimentadas por relatos de uma associação entre lesões de neurocisticercose calcária (CNL) e esclerose hipocampal (HS) de centros especializados em epilepsia em regiões endêmicas de Taenia solium. O debate que surge desses relatórios é se a associação é causal. Se bem as evidências para a associação não são de alta qualidade, são suficientemente persuasivas para merecer mais investigação com estudos longitudinais de imagens em amostras de base populacional de regiões geograficamente diversas. O outro ponto controverso é a escolha da abordagem cirúrgica para a DRE associada à CNL-HS. Três abordagens têm sido descritas: lobectomia temporal ântero-mesial padrão, lesionectomia envolvendo apenas CNL e lesionectomia com lobectomia temporal ântero-mesial (para patologia dupla); os relatórios das duas últimas abordagens são limitados. A avaliação pré-cirúrgica deve considerar as possibilidades de delinear a (s) zona (s) epileptogênica (s) de acordo com as três abordagens.

ABSTRACT

Abstract Purpose: To evaluate the morphological effects of injected sclerosing agents into the liver. Methods: This study was performed on twenty dogs, distributed into five groups: Group 1 (n = 5) - control, Group 2 (n = 5) - injection of 50% glucose solution inside hepatic parenchyma and animals followed during seven days, Group 3 (n = 10) - injection of ethanol inside hepatic parenchyma and animals distribution into two subgroups Subgroup 3A (n = 5) - followed during 24 hours and subgroup 3B (n = 5) - followed during seven days (group 3B), Group 4 (n = 5) - ethanol injection inside left portal vein branch and followed during 24 hours. Livers were macroscopically evaluated, submitted to hepatic arteriography and portography, then histology. Results: All animals in Group 4 died within 23 hours due to diffuse hepatic necrosis. The animals of groups 2 and 3 had a satisfactory evolution. Fibrosis formed in the segment reached by the sclerosant solution and interruption of the contrast flow injected into the portal system. Conclusion: Intrahepatic parenchymal ethanol injection is well tolerated and causes sclerosis restricted to a specific segment; however, intraportal ethanol injection causes massive hepatic necrosis and can lead to death.
