Abstract
The study of anthropoid nonhuman primates has provided valuable insights into frontal cortex function in humans, as these primates share similar frontal anatomical subdivisions (Murray et al. 2011). Causal manipulation studies have been instrumental in advancing our understanding of this area. One puzzling finding is that macaques with bilateral aspiration removals of orbitofrontal cortex (OFC) are impaired on tests of cognitive flexibility and emotion regulation, whereas those with bilateral excitotoxic lesions of OFC are not (Rudebeck et al. 2013). This discrepancy is attributed to the inadvertent disruption of fibers of passage by aspiration lesions but not by excitotoxic lesions. Which fibers of passage are responsible for the impairments observed? One candidate is cholinergic fibers originating in the nucleus basalis magnocellularis (NBM) and passing nearby or through OFC on their way to other frontal cortex regions (Kitt et al. 1987). To investigate this possibility, we performed unilateral aspiration lesions of OFC in three macaques, and then compared cholinergic innervation of the anterior cingulate cortex (ACC) between hemispheres. Histological assessment revealed diminished cholinergic innervation in the ACC of hemispheres with OFC lesions relative to intact hemispheres. This finding indicates that aspiration lesions of the OFC disrupt cholinergic fibers of passage, and suggests the possibility that loss of cholinergic inputs to ACC contributes to the impairments in cognitive flexibility and emotion regulation observed after aspiration but not excitotoxic lesions of OFC.

Abstract
The efficient removal of organic contaminants from wastewater is, nowadays, a prominent area of study due to its biological as well as environmental significance. Antibiotics are now found in wastewater because of their high use, which has become a source of aquatic pollution. These antibiotics have dangerous implications for people’s health. Hence, effective pharmaceutical removal from wastewater and contaminated water bodies, especially the removal of antibiotics, is of major interest to global research organizations. This is why it is necessary to investigate this class of toxic material in wastewater discharge. We synthesized three different coordination polymers (CPs) in the presence of various assistant carboxylate linkers, namely, [Zn(Hbtc)(dip)]n (1), [Zn4(1,2-bdc)4(dip)4]n (2), and [Zn(1,4-bdc)(dip)]n (3) (3,5-di(1H-imidazol-1-yl)pyridine = dip, 1,3,5-benzenetricarboxylic acid = H3btc, 1,2-benzenedicarboxylic acid = 1,2-H2bdc, and 1,4-benzendicarboxylic acid = 1,4-bdc). These CPs were characterized by using different techniques, including single-crystal X-ray diffraction. The structural studies demonstrated that in 2, there are four Zn(II) centers and both centers are in different coordination environments (Zn2 has distorted tetrahedral geometry, whereas Zn1, Zn3, and Zn4 have square pyramidal geometry). Hirshfeld surfaces analysis revealed that different types of intermolecular interactions (C⋯C, H⋯C, H⋯H, O⋯C, N⋯H, and O⋯H) are present in the synthesized CPs. We examined the different antibiotics, such as metronidazole (MDZ), nitrofurazone (NFZ), dimetridazole (DTZ), sulfasalazine(SLA), and oxytetracycline (OXY), degradation behaviors of the synthesized CPs, which showed remarkable degradation efficiency. 1 showed photocatalytic behavior toward the NFZ antibiotic in an aqueous media. This study also showed that these catalysts are stable and reusable under mild conditions.

Abstract
INTRODUCTION The aim of our study was to assess the clinical outcome of isolated lymph node recurrence in patients with epithelial ovarian cancer treated by surgery and to analyze the impact of various clinico-pathological factors on prognosis. MATERIAL AND METHODS We conducted a retrospective analysis of all the epithelial ovarian cancer patients who underwent secondary lymphadenectomy surgery for isolated lymph node recurrence at our institute from 2013 to 2020. Univariate analysis of various factors influencing the post-recurrence disease free survival and post-recurrence survival was done using Kaplan-Meier for categorical variables and cox-proportional hazard progression for continuous variables. RESULTS A total of 21 patients of isolated lymph node recurrence were treated surgically during the study period. The median disease free interval to develop lymph nodal recurrence was 13 months. All the patients achieved complete resection to no gross residual disease without any significant morbidity associated with the procedure. The median post-recurrence disease free survival after treatment of lymph node recurrence was 25 months with 3-year post-recurrence survival of 72% and 3-year overall survival of 85%. Amongst the factors influencing post-recurrence disease free survival, young age (< 50 years), para-aortic lymph node dissection at initial surgery and single site of lymph node recurrence were significantly associated with better prognosis. A single site of lymph node recurrence was associated with significantly better post-recurrence survival. CONCLUSIONS Complete resection is feasible for epithelial ovarian cancer patients presenting with isolated lymph node recurrence, without any significant perioperative morbidity. When combined with postoperative adjuvant chemotherapy, complete resection is associated with favourable survival outcomes. Young age, para-aortic lymph node dissection during primary surgery and single site of lymph node recurrence are associated with better prognosis.

Abstract
A Biobank/Biorepository is an organized collection of resources that can be accessed to retrieve biological material and data for research purpose. Human specimen repositories (adult and paediatric) take lead amongst the various types of biorepositories. Patient's bio samples are a rich source of genetic information and therefore can form the basis of diagnostics, forensics and multidimensional disciplines of biomedical research. The advent of molecular techniques and the technological upsurge in the management of genetic resources has facilitated the human DNA sampling and data collection leading to the emergence of DNA banking. DNA banking has paved a new path in precision oncology and personalized medicine. This article highlights the current scenario concerning the general awareness, scientific consciousness and current national and international practices being initiated and in practice for the establishment of bio banking facilities particularly DNA bio banking.

Abstract
PURPOSE There is a growing evidence showing that there are geographic differences in hepatocellular carcinoma (HCC). Little is known about the characteristics of hepatocellular carcinoma in the Arabian Peninsula. The present study examines the presentation and outcomes of HCC in a single institution. METHODS A retrospective chart review of patients presented with advanced-stage HCC to Kuwait Cancer Control Center (KCCC) between 2008 and 2018 was conducted. Data collected included patients demographics, HCC risk factors, performance status, Child-Pugh score, pick up of sorafenib, and survival. RESULTS About 111 cases were analyzed. The mean age of the cohort was 61.8 ± 11.4 years and 94 patients (84.7%) were males. HCV and diabetes were the most common risk factors for HCC and presented in 60 patients (54.1%) and 45 patients (40.5%), respectively. About 78 (70.3%) patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 at presentation. Only 29 (26.1%) patients presented with Child-Pugh class A, while 42 (40.4%) patients received sorafenib. The median overall survival was only 3 months. CONCLUSIONS In our cohort, HCV and diabetes were the main risk factors for HCC. The majority of patients was not amenable to sorafenib treatment and carries a very poor prognosis.

Abstract
It is known that the organic units in hybrid halide perovskites are free to rotate, but it is not clear if this freedom is of any relevance to the structure-property relationship of these compounds. We have employed quasi-elastic neutron scattering using two different spectrometers, thus providing a wide dynamic range to investigate the cation dynamics in methylammonium lead bromide (MAPbBr3) and formamidinium lead bromide (FAPbBr3) over a large temperature range covering all known crystallographic phases of these two compounds. Our results establish a plastic crystal-like phase forming above 30 K within the orthorhombic phase of MAPbBr3 related to 3-fold rotations of MA units around the C-N axis with an activation energy, Ea, of ∼27 meV, which has no counterpart in the FA compound. MA exhibits an additional 4-fold orientational motion of the whole molecule via rotation of the C-N axis itself with an Ea of ∼68 meV common for the high-temperature tetragonal and cubic phases. In contrast, the FA compound exhibits only an isotropic orientational motion of the whole FA unit with Ea ≈ 106 meV within the orthorhombic phase and a substantially reduced common Ea of ∼62 meV for the high-temperature tetragonal and cubic phases. Our results suggest that the rotational dynamics of the organic units, crystallographic phases, and physical properties of these compounds are intimately connected.

Abstract
Abstract
Introduction/Objective
Myeloid sarcoma within the central nervous system is a rare presentation of an infiltrative mass of immature myeloid cells. It is typically found in association with myeloid dysplastic syndrome, myeloproliferative disorder, or acute myeloid leukemia. Rarely, it can occur in the absence of these diseases.
Methods
We present the case of 68-year-old female with worsening nausea and headaches. Brain MRI showed diffuse pachymeningeal enhancement with numerous nodular enhancing extra-axial masses overlying both cerebral hemispheres.
Results
Open biopsy of these masses showed gelatinous, hemorrhagic, brown tissue measuring 3.0 x 2.0 x 0.7 cm. Histologically, the specimen shows a diffuse polymorphous atypical myeloid proliferation consisting of all three cell lineages. There are nodules composed predominantly of large blastoid cells with 1 to 2 prominent oblong nucleoli, consistent with erythroblasts and early erythroid precursors. In between the nodules there are myeloid cells in different stages of maturation, including numerous eosinophilic precursors. Scattered megakaryocytes are also identified.
Immunohistochemistry shows positivity for E-cadherin, CD235a and spectrin which highlight the immature erythroid cells. MPO, muramidase, and CD33 are positive in myeloid elements. Eosinophilic peroxidase highlights numerous eosinophilic precursors. CD34 is positive in the endothelial cells and very rare hematopoietic cells. CD20 and PAX 5 highlights B-cells, CD3 highlights T-cells, and CD4 highlights monocytic precursors, monocytes, histiocytes and a subset of T-cells.
Conclusion
Additional work up at the time of biopsy including FLOW cytometry and bone marrow biopsies showed no evidence of hematologic pathology. In summary the histologic and immunohistochemical findings demonstrate a tumor composed of proliferating immature myeloid cells most consistent with myeloid sarcoma without any evidence of hematological disease.

Abstract
Aims The prevalence of premature coronary artery disease (CAD) in India is two to three times more than other ethnic groups. Untreated heterozygous familial hypercholesterolemia (FH) is one of the important causes for premature CAD. As the age advances, these patients without treatment have 100 times increased risk of cardiovascular (CV) mortality resulting from myocardial infarction (MI). Recent evidence suggests that one in 250 individuals may be affected by FH (nearly 40 million people globally). It is indicated that the true global prevalence of FH is underestimated. The true prevalence of FH in India remains unknown. Methods A total of 635 patients with premature CAD were assessed for FH using the Dutch Lipid Clinical Network (DLCN) criteria. Based on scores, patients were diagnosed as definite, probable, possible, or no FH. Other CV risk factors known to cause CAD such as smoking, diabetes mellitus, and hypertension were also recorded. Results Of total 635 patients, 25 (4%) were diagnosed as definite, 70 (11%) as probable, 238 (37%) as possible, and 302 (48%) without FH, suggesting the prevalence of potential (definite + probable) FH of about 15% in the North Indian population. FH is more common in younger patients, and they have lesser incidence of common CV risk factors such as diabetes, hypertension, and smoking than the younger MI patients without FH (26.32% vs.42.59%; 17.89% vs.29.44%; 22.11% vs.40.74%). Conclusion FH prevalence is high among patients with premature CAD admitted to a cardiac unit. To detect patients with FH, routine screening with simple criteria such as family history of premature CAD combined with hypercholesterolemia, and a DLCN criteria score >5 may be effectively used.

Abstract
INTRODUCTION Dual antiplatelet therapy with clopidogrel and aspirin is the current standard of care in the management of patients with coronary artery disease (CAD) and acute coronary syndrome (ACS). The variability in response to these antiplatelet agents may be due to the underlying genetic diversity. This study was designed to determine the resistance to aspirin and clopidogrel in Indian patients and to look for correlation, if any, with selected polymorphisms. METHODS Platelet function testing by light transmission aggregometry was performed on 72 patients with CAD/ACS who were stable on dual antiplatelet therapy (clopidogrel 75 mg OD and aspirin 150 mg OD) along with 72 controls. Aspirin resistance was considered as mean platelet aggregation ≥ 70% with 10 μm ADP and ≥ 20% with 0.75 mm arachidonic acid. Clopidogrel resistance was defined as <10% decrease from the baseline in platelet aggregation in response to ADP 10 μm and semi-response as <30% decrease from the baseline. Polymorphisms CYP2C19*2, *3, CYP3A5*3 and PLA1/A2 were genotyped. RESULTS We found 51.4% patients with inadequate response to clopidogrel (1.4% resistant and 50% semi-responders) and 5.5% patients semi-responders to aspirin, none being completely resistant. The genotype and allele frequencies of CYP2C19*2 and PLA1/A2 gene polymorphisms were significantly different between clopidogrel semi-responders and responders. Carriers of CYP2C19*2 and CYP3A5*3 showed diminished inhibition of platelet aggregation. No significant correlation was found between coronary events, type of coronary intervention with clopidogrel nonresponsiveness. CONCLUSION Unlike aspirin, a high proportion of partial responders to clopidogrel were identified. In an interim analysis on 72 Indian patients, a significant association was found between CYP2C19*2 and PLA1/A2 in clopidogrel semi-responders.

Abstract
BACKGROUND Kaposi sarcoma (KS) is a vascular neoplasm associated with human herpesvirus 8 (HHV-8). Skin and mucous membranes are the most common sites, but other organs may be involved. Skeletal KS is rare and occurs either by direct spread of mucocutaneous lesions or through dissemination. Patients present with bone pain and lytic lesions for which they may undergo fine-needle aspiration (FNA). While there are about 70 published case reports of skeletal KS, there is limited literature specifically describing its cytomorphology. Our literature search yielded only a single prior reported case of FNA biopsy of skeletal KS in a Nigerian AIDS patient. CASE We present a case of disseminated KS of the axial skeleton in a 45-year-old African-American man with AIDS which was diagnosed on FNA cytologic examination. The patient presented with multiple lytic lesions in the axial skeleton. The aspirate, core-needle biopsy and touch imprint cytology of a bone lesion demonstrated clusters of spindle and epithelioid cells in radial and streaming arrangement with indistinct intercytoplasmic borders, elongated nuclei, fine chromatin and inconspicuous nucleoli. Immunohistochemical studies revealed positivity for HHV-8 and vascular markers. The cytomorphologic and ancillary features of the case are presented and discussed.

Abstract
A 60-year-old woman presented to the accident and emergency department with a 3-day history of lower abdominal pain, which was sudden in onset, localised to the right iliac fossa, constant and aggravated by movements. On examination, she was febrile (100 · F), tachycardic and normotensive. Examination of the abdomen revealed an ill-defined tender mass in the right iliac fossa. A clinical diagnosis of appendicular mass was made and treated conservatively. After a few days the mass became smaller, firmer, mobile and non-tender. Since the mass persisted, the patient was investigated further to rule out carcinoma of the caecum. A contrast-enhanced CT (CECT) of the abdomen showed a mass with air pockets in the caecum, suggestive of caecal faecolith. After 6 weeks, appendicectomy and removal of the faecolith were performed. The postoperative period was uneventful. Histopathology of the appendix showed inflammatory changes confirming appendicitis.

Abstract
BACKGROUND Acinar cell cystadenoma (ACC) is a recently recognized cystic lesion of the pancreas that demonstrates acinar differentiation and is currently believed to behave in a benign fashion. ACC enters the differential diagnosis of pancreatic cystic lesions alongside better recognized entities such as mucinous cystic and intraductal papillary mucinous neoplasms. Although uncommon, patients with ACC can undergo fine needle aspiration (FNA) of the lesion. However, the diagnosis is rarely made on cytologic examination due to sparse cellularity. Furthermore, the eosinophilic amorphous material in the cyst lumen may be mistaken for mucin, resulting in an incorrect diagnosis of a mucinous cyst. To date, there is a paucity of literature on the cytomorphology of ACC, both in peer-reviewed publications and cytopathology texts. CASE To our knowledge, we present the first detailed case report of FNA of ACC in a 22-year-old asymptomatic female. The FNA cytology specimen was hypocellular, and the presence of amorphous secretions led to the initial diagnosis of a mucinous-type neoplasm. Following surgical resection, the cytology specimen was reviewed. CONCLUSION We discuss the cytomorphologic features of ACC along with the potential pitfalls and diagnostic implications.

Abstract
Abstract
A statistical experimental design method known as the Taguchi method was utilized to optimize the injection molding processes of poly(butylene terephthalate) (PBT) and poly(trimethylene terephthalate) (PTT) blends. Impact strength was taken as the optimized property. The significant parameters included mold temperature, injection pressure, holding pressure, injection time and holding temperature. Results of the Taguchi analysis gave mold temperatures as major influencing factor on the impact strength. The optimal processing conditions were determined through the Taguchi method giving an increase of 13.7% in impact strength for the blend. Further analysis was done to distinguish the blends dependency on temperature. Differential scanning calorimetry curves indicated the presence of recrystallization peaks that were dependent on the temperature profile the sample had received prior to testing. Polarized optical microscopy was used to show the different sphereulitic growth patterns under varying isothermal conditions. It was seen that at 90°C sphereulitic growth contained pockets of different sized spereulites. AFM imaging was also used to indicate differences in blended polymer morphology.

Abstract
The impact of pretreatment anaemia on survival in individuals with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection is not known. Moreover, HCV treatment is offered less frequently to individuals with anaemia, due to haematological side effects of the treatment regimen. This study aimed to determine the effect of HCV treatment on survival among HCV/HIV co-infected individuals with pretreatment anaemia using the Electronically Retrieved Cohort of HCV-Infected Veterans (ERCHIVES). Individuals with HCV/HIV co-infection were included in current analyses. Participants were considered treated if they were prescribed ≥ 4 weeks of HCV treatment. All-cause mortality data were obtained using record linkage. Survival analyses were performed using Cox proportional hazard models. Among 5000 HCV/HIV co-infected individuals, 1671 (33.4%) had pretreatment anaemia. In a follow-up period of up to 7 years (19,500 person-years), individuals with anaemia had significantly higher mortality rate compared with those without anaemia [144.2 (95% CI: 134.5-154.7) vs 47.5 (44.0-51.2) per 1000 person-years, respectively]. Among individuals with anaemia, HCV treatment was associated with significantly lower mortality rate [66.6 (44.3-100.2) vs 149.6 (139.2-160.5) per 1000 person-years, for treated vs untreated, respectively]. Treatment remained associated with substantial survival benefit after taking into account the effect of multiple comorbidities (hazards ratio: 0.34, 95% CI: 0.21-0.62). These data suggest that HCV/HIV co-infected individuals with pretreatment anaemia have significantly higher mortality compared with those without anaemia. HCV treatment is associated with substantial survival benefit in this group. Additional studies are needed to determine strategies to improve HCV treatment rates among this group.

Abstract
AIMS To study the profile of irritable bowel syndrome (IBS), and the frequency of such symptoms among the general population, in India. METHODS In this prospective, multi-center study, data were obtained from 2785 patients with chronic lower gastrointestinal symptoms (complainants) with no alarm feature and negative investigations for organic causes visiting physicians at 30 centers, and from 4500 community subjects (non-complainants), using separate questionnaires. RESULTS Most complainants were middle-aged (mean age 39.4 years) and male (1891; 68%). The common symptoms were: abdominal pain or discomfort (1958; 70%), abdominal fullness (1951; 70%); subjective feeling of constipation (1404 of 2656; 53%), or diarrhea (1252 of 2656, 47%), incomplete evacuation (2134; 77%), mucus with stools (1506; 54%), straining at stools (1271; 46%), epigastric pain (1364; 49%) and milk intolerance (906; 32%). Median stool frequency was similar in patients who felt they had constipation or those who felt they had diarrhea. Information to subtype symptoms using standard criteria was available in 1301 patients; of these, 507 (39%) had constipation-predominant IBS ( 3 <or= stools/week), 50 (4%) had diarrhea-predominant IBS (>3 stools/day) and 744 (57%) had indeterminate symptoms. Among non-complainants, most subjects reported daily defecation frequency of one (2520 [56%]) or two (1535 [34%]). Among non-complainants, 567 (12.6%) reported abdominal pain, 503 (11%) irregular bowel, 1030 (23%) incomplete evacuation, 167 (4%) mucus and 846 (18%) straining at stools; a combination of abdominal pain or discomfort relieved by defecation, and incomplete evacuation was present in 189/4500 (4.2%) community subjects. CONCLUSIONS Most patients with IBS in India are middle-aged men, and have a sense of incomplete evacuation and mucus with stools. Abdominal pain or discomfort is frequent but not universal. Importantly, stool frequency was similar irrespective of whether the patients felt having constipation or diarrhea. Most (90%) non-complainant subjects had 1 or 2 stools per day; symptoms complex suggestive of IBS was present in 4.2% of community subjects.

Abstract
Paragangliomas are usually low-grade neoplasms with a benign natural history. While the treatment of paraganglioma has historically been controversial, surgery and radiotherapy have become standardized as therapies of choice for primary therapy. More recently, stereotactic radiosurgery has been used effectively against this rare tumor. The development of metastatic disease in patients with paraganglioma is an unusual and challenging event. This case report and review describes the specific features of this disease and the multiple therapeutic options.

Abstract
PURPOSE To evaluate intracranial tuberculomas using quantitative magnetic resonance (MR) techniques such as T2 relaxometry, magnetization transfer (MT), and diffusion-weighted imaging (DWI). MATERIAL AND METHODS Thirty-three patients with intracranial tuberculomas (histologically confirmed in 22) were evaluated using proton density/T2-weighted, T1-weighted (with and without MT), and echo-planar diffusion-weighted imaging sequences. T2 relaxation times, MT ratios (MTR), and apparent diffusion coefficient (ADC) values were calculated from the center of the lesion, the periphery, perilesional edema, and contralateral normal white matter. The mean and standard deviation values of each variable were calculated and correlated using Pearson's test (P = 0.05). RESULTS The measured mean values of T2 relaxation time, MTR, and ADC in the center of lesions were 155.5 ms, 14.1, and 1.27 x 10(-3) mm(2)/s, respectively, compared to 117 ms, 23.72, and 0.74 x 10(-3) mm(2)/s in normal white matter, and a T2 relaxation time of 187.45 ms in normal gray matter. Significant inverse correlations were noted between T2 relaxation values and MTR (P<0.001) and between MTR and ADC (P = 0.046). Significant positive correlation was seen between T2 relaxation and ADC values (P = 0.03). CONCLUSION Intracranial tuberculomas are characterized by relatively short T2 relaxation times (compared to normal gray matter), decreased MTR, and mostly no restriction of diffusion. A combination of these quantitative parameters could be of help in the noninvasive diagnosis of tuberculomas.

Abstract
Severe malaria is invariably caused by Plasmodium falciparum. In India, both adults and children are affected by severe malaria. However, children are more prone for developing anemia and convulsions as manifestations of severe malaria, while acute renal failure and jaundice are more common among adults. Pregnant women are vulnerable to hypoglycemia, anemia and pulmonary complications. The case-fatality rate due to severe malaria is 10-15% in spite of therapy but it increases in the presence of renal failure or respiratory distress (pulmonary edema or ARDS). Of late, multi-organ failure and high mortality figures are being reported increasingly from different parts of India. Early diagnosis and prompt treatment will reduce the mortality due to malaria. Cerebral malaria should always be suspected in a patient with altered sensorium in a malaria-endemic area. However, other causes of unconsciousness such as encephalitis, meningitis or hepatic coma should also be excluded. Parenteral quinine is the mainstay of therapy. A recent multi-centric study has demonstrated the efficacy of intravenous artesunate in reducing the mortality by 30%. The usefulness of adjunct therapy is still controversial.

Abstract
INTRODUCTION Colloid cysts of the 3rd ventricle are relatively rare intracranial tumours, more so in children. They are benign tumours with excellent prognosis if diagnosed and treated early. METHODS A retrospective analysis of 18 cases of colloid cysts in children below 18 years, operated in our institution between September 1998 and November 2003 (5 years) was made. Clinical presentation, radiological findings, surgical approaches and outcome were analysed. RESULTS Age ranged from 7 to 18 years. The male-to-female ratio was 12:6. Headache and vomiting were the most common symptoms. Papilloedema was the most common clinical sign. Pre-operative CT showed a hyperdense non-enhancing lesion in the majority. Twelve patients underwent a transcallosal, 2 a transcortical and 4 an endoscopic approach. Ventriculoperitoneal shunts were done in 5 patients. Postoperatively 2 patients developed epidural haemorrhage which required evacuation. One patient was re-explored for symptomatic residue. A mean follow-up of 10.2 months was available in 9 patients; the majority were asymptomatic. CONCLUSION Colloid cysts though rare are increasingly detected in children. Their early recognition and treatment give excellent results.

Abstract
CASE REPORT Four cases of medulloblastoma with extensive nodularity (MBEN) are described. The patients were 3 years of age or younger at diagnosis. Cranial CT scan disclosed multiple coalescing nodules with peculiar 'grape-like' architecture in three patients. A near total excision of the tumour was performed in all four patients. The patients are currently receiving radiation and chemotherapy. Histologically, the tumours were characterized by extreme nodularity with intranodular uniformity and low proliferative index. The internodular zones were extremely cellular, composed of undifferentiated, mitotically active cells. Bcl-2 protein expression was observed in the cellular zones but was distinctly absent within nodules. DISCUSSION MBEN represents a variant that occurs in very young children but has a good prognosis. The favourable outcome is probably related to its spontaneous neurocytic differentiation. The pattern of Bcl-2 immunoreactivity in MBENs indicates that this protein could be a key player in the regulation of neuronal differentiation in medulloblastomas.

Abstract
AIMS The aim of this study was to establish whether nimodipine given orally soon after severe diffuse head injury for a period of three weeks improved outcome. MATERIAL AND METHODS The present report analyzes the results of a prospective randomized double-blind placebo-controlled trial of nimodipine in 97 severe head injury patients (GCS Score < or =8) treated at the Department of Neurosurgery, NIMHANS, between January 1995 and June 1996. The patients were randomly assigned to two groups which were matched for age, sex, mode of injury, time interval from injury to admission, neurological status and CT scan findings. One group was given nimodipine 30 mg Q6H and the other group was given a placebo. The outcome of these patients at 6 months was evaluated using the Glasgow Outcome Score by and a psychologist. RESULTS Results showed no significant difference in the functional and psychological outcome between the two groups, even in patients with subarachnoid hemorrhage. No adverse drug events were recorded. CONCLUSION Oral nimodipine given for three weeks does not improve outcome in patients with severe diffuse head injury.
