Four-Way Wada: SEEG-based mapping with electrical stimulation, high frequency activity, and phase amplitude coupling to complement traditional Wada and functional MRI prior to epilepsy surgery.

Presurgical evaluation of refractory epilepsy involves functional investigations to minimize postoperative deficit. Assessing language and memory is conventionally undertaken using Wada and fMRI, and occasionally supplemented by data from invasive intracranial electroencephalography, such as electrical stimulation, corticortical evoked potentials, mapping of high frequency activity and phase amplitude coupling. We describe the comparative and complementary role of these methods to inform surgical decision-making and functional prognostication. We used Wada paradigm to standardize testing across all modalities. Postoperative neuropsychological testing confirmed deficit predicted based on these methods.

Oncology clinical trial disruption during the COVID-19 pandemic: a COVID-19 and cancer outcomes study.

BACKGROUND: COVID-19 disproportionately impacted patients with cancer as a result of direct infection, and delays in diagnosis and therapy. Oncological clinical trials are resource-intensive endeavors that could be particularly susceptible to disruption by the pandemic, but few studies have evaluated the impact of the pandemic on clinical trial conduct. PATIENTS AND METHODS: This prospective, multicenter study assesses the impact of the pandemic on therapeutic clinical trials at two large academic centers in the Northeastern United States between December 2019 and June 2021. The primary objective was to assess the enrollment on, accrual to, and activation of oncology therapeutic clinical trials during the pandemic using an institution-wide cohort of (i) new patient accruals to oncological trials, (ii) a manually curated cohort of patients with cancer, and (ii) a dataset of new trial activations. RESULTS: The institution-wide cohort included 4756 new patients enrolled to clinical trials from December 2019 to June 2021. A major decrease in the numbers of new patient accruals (-46%) was seen early in the pandemic, followed by a progressive recovery and return to higher-than-normal levels (+2.6%). A similar pattern (from -23.6% to +30.4%) was observed among 467 newly activated trials from June 2019 to June 2021. A more pronounced decline in new accruals was seen among academically sponsored trials (versus industry sponsored trials) (P < 0.05). In the manually curated cohort, which included 2361 patients with cancer, non-white patients tended to be more likely taken off trial in the early pandemic period (adjusted odds ratio: 2.60; 95% confidence interval 1.00-6.63), and substantial pandemic-related deviations were recorded. CONCLUSIONS: Substantial disruptions in clinical trial activities were observed early during the pandemic, with a gradual recovery during ensuing time periods, both from an enrollment and an activation standpoint. The observed decline was more prominent among academically sponsored trials, and racial disparities were seen among people taken off trial.

Longitudinal neurodevelopmental profile of a pediatric patient with de novo SPTAN1, epilepsy, and left hippocampal sclerosis.

Pathogenic variants in SPTAN1 result in abnormal neurodevelopment but limited information is available on the spectrum of neurodevelopmental profiles associated with variations in this gene. We present novel data collected at two time points over a three-year period in a nine-year-old patient with heterozygous de novo SPTAN1 variant, drug-resistant epilepsy, and left hippocampal sclerosis. Across evaluations, our patient's performance was highly variable, ranging from below age expectation to within age-expected range. The patient exhibited relative cognitive strengths at both time points on verbal-expressive tasks. Weaknesses were seen in her attention, executive function, psychomotor processing speed, fine motor, visual-motor integration, and social skills. Memory findings were consistent those associated with left hippocampal sclerosis. Evaluations resulted in diagnoses including attention deficit hyperactivity disorder and autism spectrum disorder.

Manifestaciones orales y disfunción olfativa y gustativa en el síndrome respiratorio agudo severo por corona virus 2 (VIRUS SARS-COV-2): una revisión sistemáticaA / Oral Manifestations and Olfactory and Gustatory Dysfunction in Severe Acute Respiratory Syndrome Corona Virus 2 (SARSCov-2 Virus) Disease: A Systematic Review

La enfermedad del corona virus 2 del síndrome respiratorio agudo severo (virus SARS-CoV-2) apareció por primera vez en diciembre de 2019 en Wuhan, China, y desde entonces se ha extendido rápidamente por todo el mundo. Desde entonces, el brote de esta grave enfermedad viral se ha convertido en una amenaza global para la humanidad. El diagnóstico precoz y el aislamiento son las medidas más importantes necesarias para prevenir su propagación. La evidencia anecdótica reciente ha sugerido manifestaciones orales con o sin deterioro olfativo y gustativo en asociación con la enfermedad por coronavirus (COVID-19). La enzima convertidora de angiotensina-2 (ECA-2) se expresa en la mucosa oral en grandes cantidades y, por tanto, puede contribuir a las primeras manifestaciones de esta enfermedad viral mortal. Las manifestaciones bucales de la enfermedad por coronavirus pueden presentarse en forma de lesiones ulcerativas irregulares en relación con diferentes partes de la cavidad oral y, en particular, en relación con la mucosa adherida en la región del paladar duro, así como inflamación y posterior atrofia de las diversas papilas de la lengua. La disfunción olfativa y gustativa asociada también puede conducir a una pérdida parcial y / o incluso completa de la capacidad para oler y saborear en las primeras etapas del inicio de la enfermedad. La evidencia también ha sugerido la presencia de ácido nucleico del SARS-CoV-2 en la saliva humana, lo que la convierte en portadora de la enfermedad viral infecciosa y ayuda en su diagnóstico. Hemos buscado sistemáticamente la base de datos médica para el mismo y hemos revisado toda la literatura disponible hasta el 29 de junio de 2020

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2 virus) disease had first appeared in December 2019 in Wuhan, China and has been spreading quickly throughout the world since then. Since then, the outbreak of this severe viral disease has become a global threat to humanity. An early diagnosis and isolation are the most significant measures required to prevent its spread. Recent anecdotal evidence has suggested oral manifestations with or, without olfactory and gustatory impairment in association with corona virus disease (COVID-19). Angiotensin converting enzyme-2 (ACE-2) is expressed in oral mucosa in large amounts and can, thus, contribute in the early manifestations of this deadly viral disease. The oral manifestations of corona virus disease can occur in the form of irregular ulcerative lesions in relation to different parts of the oral cavity and particularly, in relation to the attached mucosa in the hard palate region as well as inflammation and subsequent, atrophy of the various tongue papilla. The associated olfactory and gustatory dysfunction can, also, lead to partial and/or, even a complete loss of the ability to smell and taste in the early stages of the disease onset. Evidence has, also, suggested the presence of SARS-CoV-2 nucleic acid in human saliva making it the carrier of the infectious viral disease as well as aiding in its diagnosis. We have systemically searched medical database for the same and have reviewed all the literature available up to 29th of June 2020.

A seven-month-old with chronic intermittent biphasic stridor.

Paediatric stridor can indicate serious pathology and requires prompt evaluation and management. Causes range from laryngomalacia to aerodigestive tract foreign bodies. We report on a chronic presentation of paediatric stridor, discuss the workup, management and lessons learned. A seven-month-old boy presented with chronic intermittent biphasic stridor for the previous five months. Diagnostic microlaryngoscopy and bronchoscopy revealed significant localised tracheomalacia. Urgent chest computed tomography was performed to investigate further. Radiological findings revealed an oesophageal foreign body prompting immediate rigid oesophagoscopy and removal of an embedded pistachio shell. The patient had an uneventful recovery. Foreign bodies in the airway and oesophagus are quite common in children, causing symptoms from the aerodigestive tract. It is uncommon for oesophageal foreign bodies to present with stridor in the absence of digestive tract symptoms. The otolaryngologist should consider this as a diagnosis, particularly in young children with an atypical presentation and symptoms.

Non-canonical Wnt signalling regulates scarring in biliary disease via the planar cell polarity receptors.

The number of patients diagnosed with chronic bile duct disease is increasing and in most cases these diseases result in chronic ductular scarring, necessitating liver transplantation. The formation of ductular scaring affects liver function; however, scar-generating portal fibroblasts also provide important instructive signals to promote the proliferation and differentiation of biliary epithelial cells. Therefore, understanding whether we can reduce scar formation while maintaining a pro-regenerative microenvironment will be essential in developing treatments for biliary disease. Here, we describe how regenerating biliary epithelial cells express Wnt-Planar Cell Polarity signalling components following bile duct injury and promote the formation of ductular scars by upregulating pro-fibrogenic cytokines and positively regulating collagen-deposition. Inhibiting the production of Wnt-ligands reduces the amount of scar formed around the bile duct, without reducing the development of the pro-regenerative microenvironment required for ductular regeneration, demonstrating that scarring and regeneration can be uncoupled in adult biliary disease and regeneration.

Simulation-based ENT induction: validation of a novel mannequin training model.

OBJECTIVE: To ascertain whether simulation-based teaching is superior to lecture-based teaching for an induction programme using a home-made induction model. METHODS: A simulation-based induction programme was designed and separate lecture-based teaching covering the same content was organised for junior doctors. The junior doctors were asked to complete pre- and post-induction surveys regarding confidence and anxiety levels. The skills taught included microsuction, flexible nasendoscopy, and anterior and posterior nasal packing. Structured interviews were conducted after the programme to gain qualitative data for analysis. The trainees' knowledge retention was compared using a standardised written assessment one month after the session. RESULTS: Simulation-based teaching using the induction model was associated with a statistically significant increase in confidence levels and reduction in anxiety levels, and was associated with greater knowledge retention. CONCLUSION: A regular simulation induction programme should be introduced using the induction model, as it leads to better knowledge retention and increased confidence levels.

Pleural tumours and tumour-like lesions.

There are various neoplasms and tumour-like conditions of the pleura. Mesothelioma is perhaps the most widely recognised; however, there are many others that are more common and should be considered. Understanding the similarities and differences can be helpful in managing the patient with a newly found pleural lesion. We will discuss clinical symptoms at presentation and describe the imaging findings associated with these tumours, starting with conventional radiology, and correlating with computed tomography and combined positron-emission tomography (PET)/computed tomography (CT). Finally, imaging characteristics that help differentiation between the benign and malignant varieties will be reviewed.

Evidence of hepatitis A virus infection in the patients with acute encephalitis syndrome in Gorakhpur region, North India.

The etiological agent remained unidentified in a large number of patients hospitalized for acute encephalitis syndrome (AES) in 2008-2009 in Uttar Pradesh and Bihar, north India. All patients were found to present with fever and altered sensorium, while 28%, 19% and 13% showed hepatomegaly, splenomegaly and meningeal signs, respectively. Involvement mostly of children with abnormal hepatic features prompted us to undertake an exploratory study on viral hepatitis A to determine its association, if any, with hepatic derangements. AES patients (n = 2515) and healthy children (n = 167) were investigated for the presence of serum anti-hepatitis A virus (anti-HAV) IgM and anti-Japanese encephalitis (anti-JE) virus IgM by ELISA. Cerebrospinal fluids (CSFs, n = 595) and rectal swabs (n = 182) were examined for anti-HAV IgM and/or HAV RNA. Anti-HAV IgM was detected in the sera of 14.6% patients as against 6.6% of healthy children (p = 0.0042). Anti-JE virus IgM positivity was Keywords: acute encephalitis syndrome; cerebrospinal fluid; hepatitis A virus; anti-HAV IgM; non-Japanese encephalitis.

Extramedullary haematopoiesis: radiological imaging features.

Extramedullary haematopoiesis (EMH) is defined as the production of blood cells outside of the bone marrow, which occurs when there is inadequate production of blood cells. The most common causes of EMH are myelofibrosis, diffuse osseous metastatic disease replacing the bone marrow, leukaemia, sickle cell disease, and thalassemia. The purpose of this article is to review the common and uncommon imaging appearances of EMH by anatomical compartment. In the thorax, EMH most commonly presents as paravertebral fat-containing masses, and typically does not present a diagnostic dilemma; however, EMH in the abdomen most commonly manifests as hepatosplenomegaly with or without focal soft-tissue masses in the liver, spleen, perirenal space, and in the peritoneum. Hepatosplenomegaly, a non-specific feature, most often occurs without an associated focal mass, which makes suggestion of EMH difficult. EMH manifesting as visceral soft-tissue masses often requires biopsy as the differential diagnosis can include lymphoma, metastatic disease, and sarcoma. Many of these soft-tissue masses do not contain adipose elements, making the diagnosis of EMH difficult. Clinical history is crucial, as EMH would likely not otherwise be in the differential in patients with non-specific abdominal masses. Careful biopsy planning is necessary when EMH is a diagnostic consideration, given the propensity for haemorrhage. Understanding the typical imaging appearances of EMH based on its site of manifestation can help the radiologist when encountered with a finding that is diagnostic for EMH, and can help the radiologist suggest the need and plan appropriately for image-guided biopsy.

Human epidermal growth factor receptor 2 expression in gastric carcinoma and its association with histopathological parameters in Indian population.

INTRODUCTION: Gastric carcinoma is a leading cause of death worldwide with a five year survival of 10-15% even after curative resection. Trastuzumab has emerged as a potential targeted therapy in treatment of Her 2 positive gastric cancer. Her2 positivity ranges from 7-34% in studies across the world. There is a paucity of Indian studies hence a need for determination of Her2 expression in Indian population for better patient management. This study was carried out to determine the frequency of Her 2 expression in gastric carcinoma by immunohistochemistry (IHC) technique and to evaluate its association with histopathological parameters. MATERIAL AND METHODS: A total of 110 cases of gastric adenocarcinoma diagnosed on histopathological examination from July 2013 to June 2015 were included. Of these, 40 cases were resection specimens and 70 were biopsies. Histological typing of gastric carcinoma was done on the basis of Lauren classification. IHC for Her2 was done in all 110 cases. Her 2 expression was correlated with various histopathological parameters. RESULTS: Positive Her 2 expression (IHC 3+) was seen in 24.5% cases of gastric carcinoma. Patients in older age group(> 60 years) showed higher Her 2 positivity rate as compared to middle age (40-60 years) and younger population (<40 years). Higher percentage of Her 2 positivity was noted in male patients as compared to female patients. Her 2 positivity was seen more commonly in intestinal type of tumor as compared to diffuse and mixed types. Her 2 positivity was seen more in well differentiated carcinoma and higher stage tumors (pT3 and pT4). However, out of all, a statistically significant association of Her2 expression was found only with (intestinal) type of tumors (p= 0.005) and no significant association was seen with age, gender, site of tumor, tumor stage, lymph node status, lymphovascular, perineural and perinodal invasion or survival. CONCLUSION: Inspired by promising results of Trastuzumab therapy in Her 2 positive gastric carcinoma worldwide, it is recommended to routinely test all cases of gastric carcinoma for Her 2 expression and to use the targeted therapy with curative intentions in Indian population.

Distinct Alteration in Brain Endothelin A and B Receptor Characteristics Following Focal Cerebral Ischemia in Rats.

Manipulation of the central endothelin (ET) system via either ETA antagonists or ETB agonists following experimental cerebral ischemia has been shown to be beneficial in previous experimental studies. In order to further explore the involvement of these receptors in cerebral ischemia, we determined changes in binding affinity (Kd) and density (Bmax) of ETA and ETB receptors in the rat brain at 24 h and 1 week following middle cerebral artery occlusion (MCAO). Rats subject to MCAO exhibited significant neurological and motor function deficit as well as large infarct volumes (126.41±40.12 and 152.82±21.67 mm(3) on days 1 and 7, respectively). Bmax increased (P<0.01) and Kd decreased (P<0.01) for ETA receptors in the infarcted right cerebral hemisphere compared to sham 24 h post MCAO. However, after 7 days of MCAO, Bmax of ETA receptors was similar, while Kd in the infarcted hemisphere increased (P<0.05) compared to sham. Binding characteristics for brain ETB receptors were not altered 24 h post MCAO. However, 7days following MCAO, there was a significant decrease (P<0.001) in Kd values and an increase (P<0.001) in Bmax values for ETB receptors in the ischemic cerebral hemisphere. The initial increase in ETA receptors is damaging and may be aggravating cerebral ischemia due to its vasoconstrictive actions. On the other hand, since ETB receptors have been shown to enhance brain angiogenesis, it is possible that an increase in binding characteristics of these receptors is part of a natural defense mechanism to repair the ischemic brain.

Development of a high resolution plantar pressure monitoring pad based on fiber Bragg grating (FBG) sensors.

BACKGROUND: High importance is given to plantar pressure monitoring in the field of biomedical engineering for the diagnosis of posture related ailments associated with diseases such as diabetes and gonarthrosis. OBJECTIVE: This paper presents the proof-of-concept development of a new high resolution plantar pressure monitoring pad based on fiber Bragg grating (FBG) sensors. METHODS: In the proposed configuration, the FBG sensors are embedded within layers of carbon composite material (CCM) in turn conforming to an arc shape. A total of four such arc shaped sensors are instrumented in the pad at the locations of the forefoot and the hind foot. As a test of the pad, static plantar pressure is monitored on normal subjects under various posture conditions. The pad is evaluated both as a standalone platform as well as a pad inserted inside a standard shoe. RESULTS: An average pressure sensitivity of 1.2 pm/kPa and a resolution of approximately 0.8 kPa is obtained in this special configuration. The pad is found to be suitable in both configurations- stand-alone pad as well as an insert inside a standard shoe. CONCLUSION: The proposed set up offers a cost-effective high resolution and accurate plantar pressure measurement system suitable for clinical deployment. The novelty of the developed pressure pad lies in its ability to be used both as platform type as well as inserted in-sole type sensor system.

Combined application of FBG and PZT sensors for plantar pressure monitoring at low and high speed walking.

BACKGROUND: Clinical monitoring of planar pressure is vital in several pathological conditions, such as diabetes, where excess pressure might have serious repercussions on health of the patient, even to the extent of amputation. OBJECTIVE: The main objective of this paper is to experimentally evaluate the combined application of the Fibre Bragg Grating (FBG) and the lead zirconate titanate (PZT) piezoceramic sensors for plantar pressure monitoring during walk at low and high speeds. METHODS: For fabrication of the pressure sensors, the FBGs are embedded within layers of carbon composite material and stacked in an arc shape. From this embedding technique, average pressure sensitivity of 1.3 pm/kPa and resolution of nearly 0.8 kPa is obtained. These sensors are found to be suitable for measuring the static and the low-speed walk generated foot pressure. Simultaneously, PZT patches of size 10 × 10 × 0.3 mm were used as sensors, utilizing the d_{33} (thickness) coupling mode. A sensitivity of 7.06 mV/kPa and a pressure resolution of 0.14 kPa is obtained from these sensors, which are found to be suitable for foot pressure measurement during high speed walking and running. Both types of sensors are attached to the underside of the sole of commercially available shoes. In the experiments, a healthy male subject walks/runs over the treadmill wearing the fabricated shoes at various speeds and the peak pressure is measured using both the sensors. Commercially available low-cost hardware is used for interrogation of the two sensor types. RESULTS: The test results clearly show the feasibility of the FBG and the PZT sensors for measurement of plantar pressure. The PZT sensors are more accurate for measurement of pressure during walking at high speeds. The FBG sensors, on the other hand, are found to be suitable for static and quasi-dynamic (slow walking) conditions. Typically, the measured pressure varied from 400 to 600 kPa below the forefoot and 100 to 1000 kPa below the heel as the walking speed varied from 1 kilometer per hour (kmph) to 7 kmph. CONCLUSIONS: When instrumented in combination, the two sensors can enable measurements ranging from static to high speed conditions Both the sensor types are rugged, small sized and can be easily embedded in commercial shoes and enable plantar pressure measurement in a cost-effective manner. This research is expected to have application in the treatment of patients suffering from diabetes and gonarthrosis.

Conserving large carnivores: dollars and fence.

Conservationists often advocate for landscape approaches to wildlife management while others argue for physical separation between protected species and human communities, but direct empirical comparisons of these alternatives are scarce. We relate African lion population densities and population trends to contrasting management practices across 42 sites in 11 countries. Lion populations in fenced reserves are significantly closer to their estimated carrying capacities than unfenced populations. Whereas fenced reserves can maintain lions at 80% of their potential densities on annual management budgets of $500 km(-2) , unfenced populations require budgets in excess of $2000 km(-2) to attain half their potential densities. Lions in fenced reserves are primarily limited by density dependence, but lions in unfenced reserves are highly sensitive to human population densities in surrounding communities, and unfenced populations are frequently subjected to density-independent factors. Nearly half the unfenced lion populations may decline to near extinction over the next 20-40 years.

High frequency of heterozygosity in GJB2 mutations among patients with non-syndromic hearing loss.

OBJECTIVE: To determine the prevalence of GJB2 mutations among subjects with congenital, non-syndromic, sensorineural hearing loss, within a north Indian population. MATERIALS AND METHODS: This was a case-control study in which the frequencies of the three most prevalent GJB2 mutations (35delG, W24X and 167delT) were studied. Polymerase chain reaction restriction fragment length polymorphism assays were performed to detect these mutations. The entire coding region of the GJB2 gene was sequenced in all patients, and also in any of their family members who showed GJB2 mutations. RESULTS: The 35delG mutation was found to be the most prevalent mutation (21 per cent), followed by the W24X mutation (7 per cent). This is the first report of the 35delG mutation in an Indian population. One patient was a compound heterozygote for 35delG/W24X. The 167delT mutation was not observed in any patient. CONCLUSIONS: These findings challenge the classical view that the W24X variant of the GJB2 gene represents a single 'founder' mutation.

CT evaluation of shock viscera: a pictorial review.

The purpose of this article is to review both the pathophysiology and the computed tomography features of the hypoperfusion complex and shock viscera. The main findings include dilated fluid-filled loops of bowel with hyperenhancing mucosa, intensely enhancing kidneys and mesenteric vasculature, and small caliber, dense aorta and collapsed, slit-like inferior vena cava. Variable features include increased enhancement of the adrenals, decreased enhancement of the spleen, and altered enhancement of the pancreas with both hypo- and hyperenhancement described. This complex of findings indicates a tenuous hemodynamic status and has been associated with a poor prognosis. In addition, it is important to discern this collection of findings from direct injury to the viscera to aid in appropriate triage and management of the patients' injuries.

Cost-minimization analysis for Portugal of five doublet chemotherapy regimens from two phase III trials in the treatment of advanced non-small cell lung cancer.

OBJECTIVES: Economic evaluations of chemotherapy regimens for stage IIIB or IV non-small cell lung cancer (NSCLC) have been conducted for many European countries, but not for Portugal. This study evaluates the total health care costs of five commonly used doublet regimens with similar efficacy results. METHODS: Using the methodology reported by Schiller [Schiller JH, Tilden D, Aristides M, Lees M, Kielhorn A, Maniadakis N, et al. Restropective cost analysis of gemcitabine in combination with cisplatin in non-small cell lung cancer compared to other combination therapies in Europe. Lung Cancer 2004;43:101-12], we conducted a cost-minimization analysis to compare vinorelbine-cisplatin (Vin/Cis), gemcitabine-cisplatin (Gem/Cis), paclitaxel-carboplatin (Pac/Carb), docetaxel-cisplatin (Doc/Cis), and paclitaxel-cisplatin (Pac/Cis). The perspective was that of the Portuguese National Health Service and included only direct medical costs (reimbursed costs plus co-payments): chemotherapy acquisition, chemotherapy administration, hospitalizations due to adverse events, and other medical resources. Unit costs were drawn from official sources (Diagnosis Related Groups and retail/hospital costs) (2003 value [Diagnosis Related Groups (DRG) published at Diário da República; 2003]). Resource use was estimated from two multicenter randomized phase III trials [Comella P, Frasci G, Panza N, Manzione L, De Cataldis G, Cioffi R, et al. Randomized trial comparing cisplatin, gemcitabine, and vinorelbine with either cisplatin and gemcitabine or cisplatin and vinorelbine in advanced non-small-cell lung cancer: interim analysis of a phase III trial of the Southern Italy Cooperative Oncology Group. J Clin Oncol 2000;18:1451-7; Schiller JH, Harrington D, Belani CP, Langer C, Sandler A, Krook J, et al. Comparison of four chemotherapy regimens for advanced non-small-cell lung cancer. N Engl J Med 2002;346:92-8]. A time horizon of a full course of therapy was adopted. One-way sensitivity analyses were performed. RESULTS: The least and the most costly chemotherapy regimens were Gem/Cis and Pac/Carb, respectively. Total mean cost per patient was estimated at euro7083 for Gem/Cis and euro10,008 for Pac/Carb, a mean cost savings of euro2925 per patient for Gem/Cis. The differences were mainly due to the higher chemotherapy acquisition costs of Pac/Carb than for Gem/Cis. Gem/Cis was less costly in all sensitivity analyses except when 100% inpatient chemotherapy administration was assumed. CONCLUSION: Gem/Cis should be considered as a cost-saving alternative to the other four regimens in treating NSCLC patients in Portugal.

Leucocytoclastic vasculitis as a presentation of adenocarcinoma rectum.

Vasculitis has been linked to several processes, like infections, drugs and allergic, rheumatologic and neoplastic diseases. Neoplasm-associated vasculitis described in the medical literature has mostly been reported in association with haemotological neoplasms. Adenocarcinoma of rectum presenting as leucocytoclastic vasculitis is rare. We present a case of a 43-year-old male with paraneoplastic leucocytoclastic vasculitis preceding the manifestation of adenocarcinoma rectum. The vasculitis subsided on resection of the rectal malignancy and the patient did not require steroid therapy thereafter.
