Veliparib monotherapy following carboplatin/paclitaxel plus veliparib combination therapy in patients with germline BRCA-associated advanced breast cancer: results of exploratory analyses from the phase III BROCADE3 trial.

BACKGROUND: In the BROCADE3 trial, addition of the poly(ADP-ribose) polymerase inhibitor, veliparib, to carboplatin/paclitaxel improved progression-free survival (PFS) (hazard ratio 0.71, 95% confidence interval 0.57-0.88; P = 0.002) in patients with advanced human epidermal growth factor receptor 2-negative, germline BRCA1/2-mutated breast cancer. A subset of patients discontinued both carboplatin and paclitaxel before progression and continued on veliparib/placebo maintenance monotherapy until progression. Analyses in this patient subgroup are reported. PATIENTS AND METHODS: Patients were randomized 2 : 1 to veliparib plus carboplatin/paclitaxel or placebo plus carboplatin/paclitaxel. Veliparib (120 mg twice daily) or placebo was given on days -2 to 5, carboplatin (area under the curve 6 mg/ml) on day 1, and paclitaxel (80 mg/m2) on days 1, 8, and 15 of 21-day cycles. Patients who discontinued both carboplatin and paclitaxel before progression received blinded study drug monotherapy at an increased dose of 300-400 mg twice daily continuously. PFS was the primary endpoint. Exploratory analyses were carried out in the subgroup of patients who received blinded study drug as monotherapy. A time-varying Cox model including data from all patients was also used to evaluate treatment effect in the combination and monotherapy phases. RESULTS: A total of 136 of 337 patients randomized to veliparib plus carboplatin/paclitaxel and 58/172 patients randomized to placebo plus carboplatin/paclitaxel discontinued both carboplatin and paclitaxel before progression and continued on blinded veliparib or placebo monotherapy. In this blinded monotherapy subgroup, investigator-assessed median PFS from randomization was 25.7 months with veliparib versus 14.6 months with placebo. Hazard ratios from a time-varying Cox model favored veliparib during both combination therapy and monotherapy. Any-grade adverse events occurring in the monotherapy phase were primarily gastrointestinal. The most common grade ≥3 adverse events were neutropenia and anemia (4% each with veliparib; 5% and 2%, respectively, with placebo). CONCLUSIONS: Veliparib maintenance monotherapy had a tolerable safety profile and may extend PFS following combination chemotherapy.

Papilloedema: diffusion-weighted imaging of optic nerve head.

AIM: To establish the correlation between clinical grading of papilloedema and diffusion abnormalities of optic nerve head (ONH) on diffusion-weighted imaging (DWI). MATERIALS AND METHODS: Brain magnetic resonance imaging (MRI), including readout segmented echo planar imaging-based DWI, was performed in 32 patients with papilloedema and the same number of age- and sex-matched controls. Clinical grading of papilloedema was done according to the modified Frisén scale. Two neuroradiologists independently evaluated the MRI for ONH hyperintensity and apparent diffusion coefficient (ADC) value of ONH. The comparison between papilloedema clinical grade and qualitative grade of ONH hyperintensity and its presence between cases and control groups were done using the Chi-square test and Fisher's exact test, respectively. The comparison between mean ADC value of ONH among different grades and between cases and controls were done using analysis of variance (ANOVA)-F-test and Student's t-test, respectively. Receiver operating characteristic (ROC) analysis was done to calculate a cut-off ADC value between the case and control groups. RESULTS: Significant correlation between ONH hyperintensity and mean ADC value of ONH with clinical grades of papilloedema and between cases and control groups were found. ONH hyperintensity was found to be a highly sensitive (87.5% for both) and specific (specificity 97.1% and 98.6% for two observers) sign of papilloedema. A mean cut-off ONH ADC value was found to have high sensitivity (96.83%) and specificity (95.31%) to distinguish between the cases and controls. CONCLUSIONS: Diffusion parameters of ONH have significant correlation with clinical grading of papilloedema and can serve as a surrogate marker for intracranial pressure.

Comparative evaluation of H&H and WFNS grading scales with modified H&H (sans systemic disease): A study on 1000 patients with subarachnoid hemorrhage.

The comparative studies on grading in subarachnoid hemorrhage (SAH) had several limitations such as the unclear grading of Glasgow Coma Scale 15 with neurological deficits in World Federation of Neurosurgical Societies (WFNS), and the inclusion of systemic disease in Hunt and Hess (H&H) scales. Their differential incremental impacts and optimum cut-off values for unfavourable outcome are unsettled. This is a prospective comparison of prognostic impacts of grading schemes to address these issues. SAH patients were assessed using WFNS, H&H (including systemic disease), modified H&H (sans systemic disease) and followed up with Glasgow Outcome Score (GOS) at 3 months. Their performance characteristics were analysed as incremental ordinal variables and different grading scale dichotomies using rank-order correlation, sensitivity, specificity, positive predictive value, negative predictive value, Youden's J and multivariate analyses. A total of 1016 patients were studied. As univariate incremental variable, H&H sans systemic disease had the best negative rank-order correlation coefficient (-0.453) with respect to lower GOS (p < 0.001). As univariate dichotomized category, WFNS grades 3-5 had the best performance index of 0.39 to suggest unfavourable GOS with a specificity of 89% and sensitivity of 51%. In multivariate incremental analysis, H&H sans systemic disease had the greatest adjusted incremental impact of 0.72 (95% confidence interval (CI) 0.54-0.91) against a lower GOS as compared to 0.6 (95% CI 0.45-0.74) and 0.55 (95% CI 0.42-0.68) for H&H and WFNS grades, respectively. In multivariate categorical analysis, H&H grades 4-5 sans systemic disease had the greatest impact on unfavourable GOS with an adjusted odds ratio of 6.06 (95% CI 3.94-9.32). To conclude, H&H grading sans systemic disease had the greatest impact on unfavourable GOS. Though systemic disease is an important prognostic factor, it should be considered distinctly from grading. Appropriate cut-off values suggesting unfavourable outcome for H&H and WFNS were 4-5 and 3-5, respectively, indicating the importance of neurological deficits in addition to level of consciousness.

Endovascular transluminal stent grafting: Treatment of choice for post lumbar spine surgery iliac arterio-venous fistulae.

Iliac vessels are prone to injury during lumbar spine surgery due to their proximity to the lumbar spine. Arterio-venous fistula formation during lumbar spine surgery is an uncommon complication and can present as an asymptomatic incidental finding to rapidly deteriorating hemodynamics leading to cardiopulmonary collapse. We have reported three patients who had symptomatic iliac arterio-venous fistula detected soon after lumbar spine surgery. All these patients were successfully treated by endovascular transluminal stent grafting. © 2013 Wiley Periodicals, Inc.

Role of multidetector abdominal CT in the evaluation of abnormalities in polyarteritis nodosa.

AIM: To identify arterial and end-organ abnormalities on abdominal computed tomography (CT) in patients with polyarteritis nodosa (PAN). MATERIALS AND METHODS: A prospective study comprising 27 consecutive patients with PAN was conducted from 2007 to 2013. Departmental ethics committee approval was obtained. All patients underwent contrast-enhanced CT comprising an arterial and a portal venous phase. Images were assessed for arterial irregularity, aneurysms, stenosis, and occlusion. End-organ changes, including infarcts, haematoma, and bowel involvement, were also recorded. RESULTS: A positive CT was recorded in 15 patients including eight females. The mean age was 32 years. The most common abnormalities were aneurysms seen in 12 patients. The renal artery was the most common site of aneurysms (n=9). The hepatic (n=3), superior mesenteric (n=3) and splenic arteries (n=1) were also involved. Contour irregularity was noted in four patients involving the hepatic, splenic, and superior mesenteric arteries. Stenosis/occlusion was also noted in seven patients. The most common end-organ abnormality was infarct (n=9), followed by bowel wall thickening (n=3), and perinephric haematoma (n=2). CONCLUSION: A combination of arterial and end-organ abnormalities on abdominal CT enables an accurate diagnosis of PAN in occult cases and may obviate the need for angiography and, sometimes, biopsy.

'Atlas shrugged': congenital lateral angular irreducible atlantoaxial dislocation: a case series of complex variant and its management.

PURPOSE: The commonly described congenital atlanto-axial dislocation and Basilar-Invagination is antero-posterior or rotational or vertical plane. However, congenital dislocation in lateral plane has received scant attention. The purpose of this manuscript is to describe this unusual entity and discuss its management. MATERIALS AND METHODS: The clinic-radiological feature of seven patients with congenital lateral angular AAD (CLAAAD) were studied and managed. The unilateral C1 facet had subluxed lateral to C2-3 complex. The C1 and C2 facets were drilled comprehensively and repositioned with distraction, placement of metallic spacers and facet manipulation after insertion of screws. The post operative outcome was studied. RESULTS: The presentation is usually with neck tilt (progressive in 3) and/or progressive spastic quadriparesis. The mean C1-2 tilt was 25.2°. C1 was bifid in six patients. C1 lateral mass was assimilated with occipital condyle on dislocated side in and the other side was normal (6 patients). The dislocated C1-2 joint was abnormally oblique as compared to contralateral side. The relationship of occiput and C1 was normal. Correction of dislocation and lateral tilt was achieved in all patients with subsequent correction of neck tilt and deficits. One patient required reoperation. CONCLUSIONS: The acute angulation of joint on one side and near normal on other side leads to differential vertical movement, further accentuated by splaying of bifid C1. The entity is seen in young patients and often present with neck tilt and spastic quadriparesis. Management requires reshaping the joints and facet manipulation. If the reshaping is inappropriate, the joint is likely to redislocate before fusion occurs.

'Pseudofacets' or 'supernumerary facets' in congenital atlanto-axial dislocation: boon or bane?

PURPOSE: Certain abnormal contact points, appearing like additional joints (pseudofacets) were observed between atlas and axis in a subset of patients with congenital atlantoaxial dislocation (CAAD). The origin, function and bearing on management of such pseudofacets remain largely undetermined. The object is to study 'pseudofacets'or 'accessory joints' in patients with CAAD and to analyze the possible genesis, role and bearing of these on surgery and fusion rates. MATERIALS AND METHODS: 35 patients with CAAD were analyzed. Reconstructed images of CT craniovertebral junction passing through these pseudo and true facets were studied. A novel method was devised to measure the faceto-isthmic angle of axis, both in patients with CAAD and normal subjects. Operative details and fusion rates were studied in patients with pseudofacets and compared with those without it. RESULTS: Eight out of 35 patients (6 Irreducible CAAD and 2 with RCAAD) had pseudofacets. These are seen posterior to the true facets and resemble partially formed joints. The C2 facet was acutely bent over its isthmus in these patients. The direction of these pseudofacets appeared to counter the abnormal mobility at C1-2 true facets. Intraoperatively, they posed a visual hindrance to reach up to true facets for placement of spacers and lateral mass screws, requiring extensive drilling. At the same time, they did help in distraction and increased the surface for fusion between C1 and C2 in cases where sublaminar wiring alone was used. Fusion rates were 100 % in patients with pseudofacets. CONCLUSIONS: Pseudofacets may be a result of genetic aberration and nature's mechanism to restrict abnormal C1-2 mobility in CAAD by imparting some stability. Their presence hinders the visualization making it difficult to reach upto the true facets, thus a bane. They may require extensive drilling when direct posterior approach is used, thereby disrupting the natural restrictive mechanism. However, the flattened surfaces provide an increased area for postoperative bony fusion between C1 and 2, making their presence a 'boon'.

Prospective study of the correlation between admission plasma homocysteine levels and neurological outcome following subarachnoid hemorrhage: a case for the reverse epidemiology paradox?

BACKGROUND: Homocysteine (tHcy) has been known over the last few decades for its putative impact on vascular diseases, but has not been evaluated much in patients with subarachnoid hemorrhage (SAH). This study was carried out to assess its prognostic impact on the neurological outcome following SAH. METHODS: Admission plasma tHcy was evaluated in 90 SAH patients and prospectively studied in relation to various factors and the Glasgow Outcome Scale (GOS) at 3 months. Univariate and multivariate analyses were performed using SPSS 21. RESULTS: tHcy was significantly higher following SAH compared to matched controls [median (IQR): 25.7 (17.3-35.9) vs. 14.0 (9.8-17.6) µmol/l, p < 0.001]. It was significantly higher in younger patients. However, systemic disease, WFNS and Fisher grades did not have a significant impact on its levels. tHcy was significantly lower among patients who died [median (IQR): 16.0 (14.4-20.6) vs. 29.7 (21.8-40.2) µmol/l, p < 0.001] and those with unfavorable outcome (GOS 1-3) [median (IQR): 21.6 (14.5-28.2) vs. 30.3 (20.4-40.7) µmol/l, p = 0.004] compared to others, with a significant continuous positive correlation between tHcy and GOS (p = 0.002). The beneficial association of tHcy with outcome was homogeneous with no significant subgroup difference. Multivariate analysis using binary logistic regression adjusting for the effects of age, systemic disease, WFNS grade, Fisher grade, site of aneurysm, clipping or coiling revealed higher tHcy to have a significant independent association with both survival (p = 0.01) and favorable outcome (p = 0.04). CONCLUSIONS: Higher homocysteine levels following SAH appear to have a significant association with both survival and favorable neurological outcome, independent of other known prognostic factors, apparently exemplifying "reverse epidemiology paradox" in which a conventional risk factor seems to impart a survival advantage.

Factors influencing feasibility of direct posterior reduction in irreducible traumatic atlantoaxial dislocation secondary to isolated odontoid fracture.

INTRODUCTION: Direct posterior reduction by intraoperative manipulation of joints for irreducible traumatic atlantoaxial dislocation (IrTAAD) has gained acceptance in the recent past. However, factors determining its feasibility have not been elucidated. Our study aims to examine the clinico-radiological factors predicting feasibility of direct posterior reduction in IrTAAD secondary to isolated odontoid fracture, in an attempt to differentiate the "truly irreducible" from those "deemed irreducible." MATERIALS AND METHODS: The onset and progression of neck pain and myelopathy was studied in 6 patients of IrTAAD with fracture odontoid, which failed to reduce despite traction. The dynamic X-rays and computed tomography (CT) scans of craniovertebral junction, along with the vertebral artery angiogram were studied to look for the slightest mobility, interface of fractured fragments, malunion, callous, and relationship of the C1-2 facets and vertebral artery. RESULTS: All 6 patients had progressive worsening of neck pain. Three patients had progressive myelopathy. Three patients presented 6 months after trauma. Radiology showed type-II fracture with IrTAAD (anterolisthesis in 5 and retrolisthesis with lateral dislocation in 1) and locked facets in all. X-rays showed doubtful callous formation in 3 patients and CT confirmed non-union. Three patients showed angular movement on dynamic X-rays despite irreducibility and locked facets. Angiogram showed thrombosis of vertebral artery in one patient. Intraoperative reduction could be achieved in all 6 patients with good clinico-radiological outcome. CONCLUSION: Worsening pain, progression of myelopathy, some movement on dynamic X-rays, a malunion ruled out on CT scan, and the presence of locked facets make direct posterior reduction feasible in patients with IrTAAD. The difficulty increases in remote fractures due to fibrosis around the dislocated joints. The role of the CT angiogram, in defining the relationship of Vertebral artery (VA) to the dislocated facets, and in determining the extent of VA injury, is vital. Preoperative detection of VA injury reduces the chance of intraoperative reduction, especially if only unilateral joint approach is planned.

Spectrum of imaging findings on MDCT enterography in patients with small bowel tuberculosis.

Abdominal tuberculosis (TB) is the sixth most common extrapulmonary site of involvement. The sites of involvement in abdominal tuberculosis, in descending order of frequency, are lymph nodes, genitourinary tract, peritoneal cavity, and gastrointestinal tract. The radiological armamentarium for evaluating tuberculosis of the small bowel (SBTB) includes barium studies (small bowel follow-through, SBFT), CT (multidetector CT, CT enterography, and CT enteroclysis), ultrasound (sonoenteroclysis), and magnetic resonance imaging (MRI; enterography and enteroclysis). In this review, we illustrate the abnormalities at MDCT enterography in 20 consecutive patients with SB TB and also describe extraluminal findings in these patients. MDCT enterography allows non-invasive good-quality assessment of well-distended bowel loops and the adjacent soft tissues. It displays the thickness and enhancement of the entire bowel wall in all three planes and allows examination of all bowel loops, especially the ileal loops, which are mostly superimposed. The terminal ileum and ileocaecal junction are the most common sites of small bowel involvement in intestinal TB. The most common abnormality is short-segment strictures with symmetrical concentric mural thickening and homogeneous mural enhancement. Other findings include lymphadenopathy, ascites, enteroliths, peritoneal thickening, and enhancement. In conclusion, MDCT enterography is a comprehensive technique for the evaluation of SB TB.

Osseous sarcoid with lytic lesions in skull.

Sarcoidosis bone is uncommon, and involvement of the skull is exceptionally rare. We present a 65-year-old obese female who presented with a 2-month history of dryness of mouth, polyuria, fatigue, and anorexia. She had generalized lymphadenopathy, organomegaly, and hypercalcemia, and a skeletal survey revealed extensive osteolytic lesions in the skull and phalanges. Both lymph node biopsy from the cervical lymph node and bone marrow examination revealed non-caseating granulomas, suggesting sarcoidosis. She was started on 1 mg/kg oral corticosteroids; during a follow-up of 6 months, she achieved normocalcemia; however, the punched-out lesions in the skull remained unchanged. This case reiterates several important issues that all lymphadenopathy in emerging nations may not be tubercular, and presence of osteolytic lesions in skull are unusual for sarcoid, at an elderly age, necessitates evaluation for more common etiologies like metastases and myeloma. Finally, patients with osseous sarcoid should be on a close follow-up since due to the rarity of this presentation, no definite consensus on the management of such cases exists in the literature.

Endovascular treatment of ruptured proximal PICA aneurysms: a single-center 5-years experience.

BACKGROUND AND PURPOSE: Posterior inferior cerebellar artery (PICA) like other intracranial arteries is prone to aneurysm formation. Aneurysms usually arise from the vertebral artery (VA) - PICA junction and the proximal segment of the PICA. The use of endovascular treatment as an alternative treatment to surgery has been increasing. We present our last 5 years' experience in treating the ruptured proximal PICA aneurysms. MATERIALS AND METHODS: Retrospective analysis of records of all patients with ruptured VA-PICA junction aneurysms treated at our referral center between July 2008 and July 2013 was performed. Over the last 5 years, we came across 17 patients who had aneurysms of proximal PICA or VA-PICA junction out of which 13 patients underwent endovascular treatment for ruptured saccular VA-PICA junction aneurysms and were the focus of this research. Follow-up studies ranged from 6 months to 3 years. RESULTS: All the patients presented with an acute intracranial hemorrhage on NCCT. All the aneurysms were at VA-PICA junction with partial or complete incorporation of PICA origin in the sac. Endovascular treatment of all the 13 aneurysm was successful in the first attempt. Aneurysms were treated with balloon assisted coiling either by placing the balloon across the VA-PICA junction (n = 3) or in the vertebral artery proper (n = 9). Stent assisted coiling VA-PICA was performed in one aneurysm (n = 1). There was no intra-procedural rupture of the aneurysms. CONCLUSION: Endovascular therapy of ruptured proximal PICA aneurysms is possible and safe with the use of adjuvant devices and should be considered as first line treatment.

Fine needle aspiration cytology in ovarian lesions: an institutional experience of 584 cases.

OBJECTIVE: To assess the diagnostic value of fine needle aspiration cytology (FNAC) in ovarian lesions. METHODS: This was a retrospective study of ultrasound-guided (US) FNAC of 584 ovarian lesions from January 1998 to July 2010. The lesions were categorized into non-neoplastic lesions, neoplastic lesions and inadequate aspirates. The results were compared with the corresponding histopathology whenever available. RESULTS: Of the 584 lesions, 180 (30.8%) were reported as non-neoplastic (48 non-specific inflammation, 11 tuberculosis, 63 functional cysts and 58 endometriotic cysts), 249 (42.6%) as neoplastic (81 benign lesions/tumours and 168 malignant) and 155 (26.5%) as inadequate. Based on the subsequent histopathology, which was available in 121 (20.7%), the cases were divided into those that were concordant and discordant. Concordant cases comprised 92/121 (76%), including 28 non-neoplastic lesions (seven non-specific inflammation, nine functional cysts and 12 endometriotic cysts), 42 surface epithelial tumours (13 benign and 29 malignant), 10 germ cell tumours (five mature cystic teratomas and five mixed germ cell tumours), seven sex-cord stromal tumours (three granulosa cell tumours, one sclerosing stromal tumour, one strümal leutoma, one Sertoli Leydig cell tumour and one malignant Sertoli cell tumour) and five miscellaneous lesions (one plasma cell tumour, two leiomyosarcomas and two cases of necrosis). Discordant cases comprised 29/121 (24%) (21were inconclusive or inadequate on cytology), including four endometriotic cysts, 14 surface epithelial tumours (one cystadenofibroma, one borderline mucinous tumour and 12 carcinomas), five germ cell tumours (two immature teratomas and three mature cystic teratomas), two thecomas, one fibroma, one sclerosing stromal tumour, one fibrosarcoma and one myxoma. FNAC sensitivity for a diagnosis of malignancy was 85.7%, specificity 98.0%, positive predictive value 97.7%, negative predictive value 87.7% and accuracy 92.0%, if 21 inconclusive/inadequate FNACs were excluded; with the latter taken as false negatives, sensitivity was 73.7% and accuracy 76.0%. CONCLUSION: FNAC has a high specificity for diagnosis of ovarian/adnexal lesions but greater experience is required for the accurate subtyping of neoplasms and sensitivity is limited by inconclusive/inadequate results.

Ventral compression in adult patients with Chiari 1 malformation sans basilar invagination: cause and management.

BACKGROUND: A small subset of patients with adult Chiari I malformation without basilar invagination (BI) and instability show ventral cervicomedullary distortion/compression and have symptoms pertaining to that. The cause of this ventral compression remains speculative. Additionally, it is unclear if these patients would require ventral decompression with posterior fusion or only posterior decompression would suffice. METHODS: Sixteen adult patients with Chiari I malformation with significant ventral cervicomedullary compression, in the absence of BI, were included in the study. Atlantoaxial dislocation (AAD) was excluded in these patients by flexion-extension craniovertebral junction X-rays and computed tomography (CT). Their clinical profile, especially symptoms pertaining to cervicomedullary compression, i.e. dysphagia, dysarthria and spasticity, were graded. The ventral cervicomedullary compression (VCMC) was quantified using pBC2 (maximum perpendicular distance to the basion-infero posterior point of the C2 body) on sagittal magnetic resonance imaging (MRI) and only those patients with pBC2 ≥9 mm were included. Furthermore, retroversion of dens and retro odonotid tissue thickness was calculated in each patient. Fifteen patients underwent posterior decompression alone and one refused surgery. Follow-up was done every 3 months. Repeat MRI was done at 1 year following surgery to look for pBC2. RESULTS: The mean pBC2 was 11 ± 0.2 mm. Retroversion of dens was responsible for VCMC in three patients and periodontoid crown in 13. There was no correlation between the tonsillar descent, age and the pBC2. All patients improved in symptoms of cervicomedullary compression following surgery. One patient worsened 6 months after initial improvement. The pBC2 did not change, as seen on follow-up MRI done in five patients. CONCLUSIONS: VCMC in adult patients with Chiari I malformation in the absence of BI and/or AAD is due to periodontoid tissue (crown) or retroverted dens. Though a long-term study is required, it appears that all patients with Chiari I malformation, irrespective of the VCMC, can be given a chance with posterior decompression alone. Transoral decompression with posterior fusion may be required in a small subset of patients who fail to improve or worsen following posterior decompression only.

An exophytic brain stem glioblastoma in an elderly presenting as a cerebellopontine angle syndrome.

Exophytic brain stem gliomas are rare and are generally seen in paediatric population. These are usually low grade gliomas. We report a case of brainstem glioblastoma in an elderly patient presenting as a cerebellopontine mass.

Ruptured cerebral aneurysm in isolated type A interrupted aortic arch managed by transradial endovascular route: A case report with literature review.

BACKGROUND AND INTRODUCTION: Interrupted aortic arch (IAA) is a very rare congenital anomaly carrying high neonatal mortality rate if left untreated. Rarer still, is its presentation in teenage or adulthood. This condition has been found to be complicated with cerebral aneurysms, which is a consequence of hemodynamic stress and hypertension secondary to arch interruption. Cerebral aneurysms can further complicate the clinical course and lead to poor clinical outcomes, especially if ruptured. CLINICAL PRESENTATION: A 17-year-old female presented with ruptured basilar top aneurysm and was considered for endovascular coiling. Transfemoral access was chosen but the catheter could not be negotiated beyond proximal thoracic aorta. A computed tomographic angiography (CTA) of thorax and abdomen was performed, which showed isolated interruption of aortic arch. Subsequently, transradial route was used for coiling of the aneurysm. CONCLUSION: To the best of our knowledge, the index case is one of the only seven cases of IAA with cerebral aneurysm that have been reported till date in medical literature. It also holds the unique distinction of being the first case of IAA with cerebral aneurysm treated by endovascular approach. Our case highlights the importance of transradial access in such pathological conditions.

Exposure to Toxocara Canis is not Associated with New-Onset Epilepsy.

Purpose: The association between exposure to Toxocara canis and epilepsy is at the best contentious. Most of previous studies were retrospective, community-based, and contradictory to one another. As the impact of a positive association on the magnitude of epilepsy will be huge especially in developing countries where toxocariasis is common owing to poor hygienic practices, this study was carried out to determine whether exposure to T. canis predisposes to development of epilepsy. Patients and Methods: This case-controlled observational study was carried out a tertiary healthcare center in North India on 120 patients with newly diagnosed epilepsy who presented within 3 months of diagnosis. A total of 120 age- and sex-matched individuals from the same community were chosen as controls. Epilepsy was defined according to ILAE 1993 definition. Serological testing for T. canis was carried out using commercially available ELISA kits. All the positive samples were subjected to Western blot testing for confirmation. Results: The prevalence of antibodies to T. canis was similar in cases (16/120; 13.3%) and controls (16/120; 13.3%). Among the various risk factors, history of pica was significantly associated with T. canis seropositivity, while lack of hand washing was significantly associated with higher risk of epilepsy. Conclusion: Our study could not find any association between exposure to T. canis and epilepsy.
