Comprehensive Analysis of Craniopharyngioma: Epidemiology, Clinical Characteristics, Management Strategies, and Role of Radiotherapy.

Background/Aim: Craniopharyngiomas pose challenges in diagnosis and management due to their rare occurrence and diverse clinical manifestations. This study aimed to provide a comprehensive analysis of cranio-pharyngioma, including its epidemiological trends, clinical presentations, radiological characteristics, surgical interventions, and the role of radiotherapy. Patients and Methods: A retrospective observational study was conducted on 23 patients diagnosed with craniopharyngioma at our hospital from August 2017 to July 2019. Data regarding demographics, clinical presentation, radiological findings, surgical interventions, and adjuvant therapies were collected and analyzed. Results: Craniopharyngiomas exhibited a bimodal age distribution, with peaks in childhood and late adulthood. Clinical presentations varied between pediatric and adult patients, with headache and nausea/vomiting predominant in children, and visual disturbances and hypogonadism more common in adults. Radiological imaging revealed predominantly suprasellar localization and varying tumor consistency. Surgical resection was the primary treatment modality, with post-operative complications including diabetes insipidus and cerebrospinal fluid leak. Histological analysis showed distinct subtypes, with the adamantinomatous subtype predominant in children and the papillary subtype in adults. Adjuvant radiotherapy was administered in cases of incomplete resection or tumor recurrence. Conclusion: This study provides comprehensive insights into the epidemiology, clinical characteristics, radiological features, surgical interventions, and role of radiotherapy in craniopharyngioma management. Understanding these aspects is crucial for tailoring optimal treatment strategies and improving patient outcomes in this complex clinical scenario.

Aberrant Subclavian Artery in Interrupted Aortic Arch with Severe Aortic Outlet Obstruction: Cerebral Blood Flow as a Possible Determinant of Embryonic Cardiovascular Development?

Aberrant subclavian artery (ASCA) is frequently observed in interrupted aortic arch (IAA) with aortic/subaortic obstruction. Developmental significance of ASCA in IAA in utero remains elusive. Newborns with prenatally diagnosed isolated IAA under continuous prostaglandin E1 infusion were studied. Cross-sectional areas of aortic valve opening (AVOCSA) and patent ductus arteriosus (PDACSA) were represented by echocardiographic measurement of (diameter)2 indexed by body surface area (m2). Types of IAA and presence of ASCA were examined in relation to sizes of AVOCSA and PDACSA. Twenty-four newborns with IAA (six type A and 18 type B) were reviewed. Male dominance was seen in type B (male 72%). Twenty-three patients had left aortic arch. No type A patients had ASCA, but 50% of type B had ASCA; AVOCSA was significantly smaller in type B than in type A (p = 0.003). In type B, PDACSA was significantly larger in those with ASCA than without (p = 0.003), but AVOCSA exhibited no significant size difference between these two subgroups. Chromosome 22q11 deletion was only seen in type B (56%) and showed no significant correlation with the presence of ASCA. In type B IAA, the presence of ASCA was associated with larger PDACSA, suggesting an adaptive enlargement of the ductus arteriosus and ASCA in response to reduced antegrade flow across small AVOCSA, which may be augmenting cerebral blood flow. Preservation of cerebral blood flow may be another important determinant affecting embryonic cardiovascular development.

Evaluation of chromosome 1p/19q deletion by Fluorescence in Situ Hybridization (FISH) as prognostic factors in malignant glioma patients on treatment with alkylating chemotherapy.

BACKGROUND: Either deletion or co-deletion of chromosomal arms 1p or 19q is a characteristic and early genetic event in oligodendroglial tumors that is associated with a better prognosis and enhanced response to therapy. Information of 1p/19q status is now regarded as the standard of care when managing oligodendroglial tumors for therapeutic options in anticipation of the increased survival and progression-free survival times associated with it. Keeping this in view, we first time attempted to establish the FISH based detection of 1p/19q deletion in glioma tissue samples to evaluate its role and involvement in the disease. METHOD: Overall 39 glioma cases of different histologies were evaluated by fluorescence in situ hybridization (FISH) technique using specific FISH probes with Olympus BX43 fluorescent microscope to detect chromosomes 1p and 19q or co-deletions therein. RESULTS: Of the 39 glioma samples, overall 27 (69.2%) were found to have deletion either in 1p, 19q or both. Deletions were observed in 23.0%, 7.6% and 38.4% in 1p, 19q and 1p/19q co-deletions respectively. Overall oligidendrioglioma presented with 53.8% (21 of 39) deletions, astrocytoma group showed 12.8% and GBM accounted for 2.5% deletions. Overall survival and disease free survival was seen significantly better in oligidendrioglioma and astrocytoma with deleted tumors as compared to non-deleted ones (p<0.05). CONCLUSION: Allelic losses on 1p and 19q, either discretely or shared, were more frequent in classic oligodendrogliomas than in either astrocytoma or Glioblastoma with better survival and response to therapy.

Adaptive Growth of the Ductus Arteriosus and Aortic Isthmus in Various Ductus-Dependent Complex Congenital Heart Diseases.

BACKGROUND: The ductus arteriosus (DA) is critical in maintaining postnatal circulation in neonates with obstructed systemic circulation (OSC) and pulmonary circulation (OPC). We hypothesized that the size of the DA and aortic isthmus (AoI) undergoes adaptive growth in utero to counteract the hemodynamic challenges in these congenital heart diseases (CHD). METHODS: Postnatal echocardiograms of neonates diagnosed prenatally with ductal-dependent CHD who were started on prostaglandins within 24 h of birth were reviewed. We assessed the cross-sectional area of the aortic valve opening, pulmonary valve opening, AoI, and DA by calculating (diameter)2/body surface area. Neonates were classified into OSC or OPC then subgrouped depending upon the patency of semilunar valves: OSC with and without aortic atresia (OSC-AA and OSC-nAA, respectively) and OPC with and without pulmonary atresia (OPC-PA and OPC-nPA, respectively). RESULTS: Ninety-four cases were studied. The DA in OSC was significantly larger than OPC, and the DA in OSC-AA was significantly larger than OSC-nAA. The size of the AoI was significantly larger in OPC than OSC and larger in OSC-AA than OSC-nAA. Within the OSC-nAA group, there was no significant difference in the size of the DA, AoI, or pulmonary valve opening between those with retrograde flow (RF) at the AoI and without (nRF) except the aortic valve opening was significantly larger in nRF. All groups had comparable cross-sectional areas of systemic output. CONCLUSIONS: Our findings suggest that DA and AoI show compensatory growth to maintain critical blood flow to vital organs against primary anatomical abnormalities in ductus-dependent CHD.

Infra-tentorial brain tumor subtypes in children and adults-surgical outcome in an ethnic population with a single regional tertiary center.

BACKGROUND: To analyze clinically and radiologically the surgical outcome like residual disease, progression of disease, recurrence, disabilities, event-free survival (EFS), and mortality of different infra-tentorial tumor subtypes in children and adults of a strictly non-migratory and ethnic population. METHODS: The 410 histologically proved, out of 589, infra-tentorial brain tumor patients were analyzed clinically and by the imaging post-surgically in a single tertiary center for an ethnic region. In this analytico-observational study, retrospectively postoperative records of 589 infra-tentorial brain tumors from November 1998 to December 2018 (20 years) were retrieved, scrutinized, and compiled. The post-operative clinic-radiological records of 410 patients with proved histopathological examination results were included. Statistical law of variance was applied where-ever necessary. RESULTS: The 63.2% of the all 410 operated infra-tentorial brain tumors were males while females predominated in meningiomas and pineoblastomas. About 31.7% infra-tentorial tumors were children (below 18 years). About 54.1% cases were histologically malignant. The residual tumors comprised 40.2% and symptoms of disease-progression occurred in 10.9%. The tumor recurrence occurred in 14.3% while 6.0% patients developed severe disability. The overall mortality was 11.4% but 18.9% in malignant tumors. The event-free survival (EFS) for all the patients was 66.0%, patients with malignancies had 47.7% and benign group had 87.7%. CONCLUSION: The study, surgical outcome of infra-tentorial brain tumor subtypes in children and adults (approx. 1/3rd of patients being children), conducted in a tertiary center at a remote land-locked location with non-migratory ethnic population as its catchment area, has a significant epidemiological value for the community and the region.

Correlation between Intraoperative Serum Lactate and New-Onset Postoperative Neurodeficits in Patients Undergoing Elective Craniotomies.

Background: Elevated lactate levels in neurosurgical patients are seen in brain tumors, traumatic brain-injury, brain infarction, and subarachnoid hemorrhage. Hyperlactatemia during craniotomy may be caused by hypotension due to multiple factors. Recently, intraoperative hyperlactatemia has been associated with fresh-onset neurodeficits. Aims: We studied the prevalence of hyperlactatemia in patients undergoing craniotomy and relationship between intraoperative hyperlactatemia and development of new postoperative neurodeficit. Study Design: Eighty-six patients, American Society of Anesthesiologists Classes I,II and III, undergoing elective craniotomy for neurosurgical indications were included in this prospective, observational study in a tertiary care center. Materials and Methods: Baseline, intraoperative, and postoperative (upto 12 h) lactate levels were noted. Neurological examination to detect new-onset neurodeficits was done at intervals up to 72 h postoperatively. Lactate levels were compared between patients who developed neurodeficits and those who did not develop neurodeficits postoperatively. Statistical Analysis: Statistical analysis of the correlation between intraoperative hyperlactatemia and fresh postoperative neurodeficit was done using the Chi-square test. Results: The prevalence of intraoperative hyperlactatemia was found to be 52.3% and that of fresh-onset postoperative neurodeficits was 31.4%. The relationship between the two was statistically insignificant (P > 0.05). Conclusion: The intraoperative hyperlactatemia is not correlated with the development of fresh-onset postoperative neurodeficit. Implications: There may be no relationship between the intraoperative lactate levels and fresh-onset postoperative neurodeficits. Multifactorial reasons may be responsible for increased lactate levels which need to be identified by further research.

Epidemiological pattern of dog bites and the occurrence of rabies in humans within Srinagar district of Kashmir Valley, India.

Men's dominant ally, best defense defendant, therefore, the pre-eminent peril detector, dogs became a threat for the humanity inflicting a fatal disease of rabies. Dog bites and open garbage dumps became additional and apparent and are serious and sometimes underestimated public health dilemma in the Kashmir region. The aesthetic, primarily health care and psycho-sociological consequences of trauma caused by a dog bites repeatedly burden the standard of lifetime pertaining to the affected persons and their family. The present study was carried in Srinagar district. Diverse sampling plan / data collection strategies were formulated to fulfill the set of objectives. To assess the epidemiological pattern, secondary source of information viz. Shri Maharaja Hari Singh hospital, which shouldered the relevant cases, was utilized. Further, people perception of the subject was assessed using a predesigned interview schedule from respondents selected by appropriate methods. West zone had recorded the highest number of cases (28.95 %), then the south zone, followed by the north zone and the east zone. Majority victims were males (74.27 %) followed by females (25.72 %) [χ2 = 4.442, p = 0.219). Most of them belonged to 30-40 (26.88 %) year old groups, followed by 20-30 (22.36 %), 10-20 (16.03 %) and so on. The time of exposure of victims was evening (62.90 %) [χ2 = 30.342, p = 0.001]. The bulk number of cases had bite on legs (56.60 %). Majority had category 3 bites (70.16 %) and the majority had received immunoglobin (82.85 %) [χ2 = 29.56, p = 0.001]. The summer season (29.30 %) had also recorded the highest number of cases followed by autumn season (27.82 %) irrespective of each determinant. The Anti rabies clinic of SMHS has also recorded two rabies deaths during this period. The majority people (72.50 %) were illiterate and belonging to lower sections of society. About all those diseases that attack humans, rabies is an example of the best known in Srinagar. Its notoriety is peculiar when assessed on its influence medially, on humans who are belonging to the susceptible divisions of the society due to lack of discernment. The lack of complete perception might decipher into higher mortality linked to rabies.

Association of strong risk of hTERT gene polymorphic variants to malignant glioma and its prognostic implications with respect to different histological types and survival of glioma cases.

BACKGROUND: Germline genetic variants of human telomerase reverse transcriptase (hTERT) are known to predispose for various malignancies, including glioma. The present study investigated genetic variation of hTERT T/G (rs2736100) and hTERT G/A (rs2736098) with respect to glioma risk. METHODS: Confirmed cases (n = 106) were tested against 210 cancer-free healthy controls by the polymerase chain reaction-restriction fragment length polymorphism technique for genotyping. RESULTS: Homozygous variant 'GG' genotype of rs2736100 frequency was > 4-fold significantly different in cases versus controls (39.6% 17.2%; p < 0.0001). Furthermore, variant 'G' allele was found to be significantly associated with cases (0.5 versus 0.2 in controls; p < 0.0001). Homozygous variant rs2736098 'AA' genotype (35.8% versus 23.8%) and allele 'A' (0.49 versus 0.34) showed a marked significant difference in cases and controls, respectively (p < 0.05). In hTERT rs2736100, the GG genotype significantly presented more in higher grades and GBM (p < 0.0001). Furthermore, the GG variant of hTERT rs2736100 had a poor probability with respect to the overall survival of patients compared to TG and TT genotypes (log rank p = 0.03). Interestingly, two haplotypes of hTERT rs2736100/rs2736098 were identified as GG and GA that conferred a > 3- and 5-fold risk to glioma patients respectively, where variant G/A haplotype was observed to have the highest impact with respect to glioma risk (p < 0.0001). CONCLUSIONS: The results of the present study indicate that hTERT rs2736098 and rs2736100 variants play an important role in conferring a strong risk of developing glioma. Furthermore, hTERT rs2736100 GG variant appears to play a role in the bad prognosis of glioma patients. Haplotypes GG and GA could prove to be vital tools for monitoring risk in glioma patients.

Histopathological Pattern and Outcome of Posterior Fossa Tumors in Children and Adults - A 20-Year Experience.

CONTEXT: The postoperative quality and span of life in posterior fossa tumors (PFTs) is complicated by the residual disease, progression, recurrence, disabilities, and mortality. AIMS: The aim of this study is to analyze the link between histopathological type of tumor and outcome in an ethnic Himalayan population of India. SETTINGS AND DESIGN: The histopathological records of 410 out of 589 patients were compared with their clinical outcome up to the 1st postoperative year in a single center which amounts to regional epidemiological value of PFTs. MATERIALS AND METHODS: In this observational study, retrospectively postoperative records of 589 PFTs from November 1990 to December 2010 (20 years) were retrieved, scrutinized, and observed. The postoperative records of 410 patients with proved histopathological examination results were included. STATISTICAL ANALYSIS USED: The statistical law of variance was applied wherever necessary. RESULTS: About 63.2% of 410 operated PTFs were males while females predominated in meningiomas and pineoblastomas. About 31.7% of PFTs were children (below 18 years.). About 54.1% of the cases were histologically malignant. The residual tumors comprised 40.2%, and symptoms of disease progression occurred in 10.9%. The tumor recurrence occurred in 14.3% while 6.0% of the patients developed severe disability. The overall mortality was 11.4% up to the 1st postoperative year, with 18.9% in malignant patients. The first 1-year event-free survival (EFS) for all the patients was 66.0%. While the patients with malignancies had the first 1-year EFS of 47.7%, the histologically benign group had 87.7%. CONCLUSION: The first 1-year postoperative EFS of histologically benign and some malignant PFTs both in children and adults such as pilocytic astrocytomas, ependymomas, and pineoblastomas was much better (87.7%) than other malignant PTFs.

Early Surgical Closure of Atrial Septal Defect Improves Clinical Status of Symptomatic Young Children with Underlying Pulmonary Abnormalities.

Elective closure of atrial septal defect (ASD) is usually recommended during preschool ages. However, ASD may contribute to deteriorating health in the presence of significant comorbidity and, thus, may need earlier closure. There is a lack of clarity regarding the indications for and outcomes after ASD closure in infancy and early childhood. We investigated the benefits and safety of surgical ASD closure in symptomatic patients under 2 years of age. Retrospective chart review was conducted in patients who underwent surgical ASD closure within the first 2 years of life. Of 31 symptomatic ASD patients, 22 had persistent respiratory symptoms, 24 failure to thrive, and 9 pulmonary hypertension. Overall, 26 patients (84.0%) showed clinical improvement after ASD closure, including improved respiratory status (17/22; 77.3%), resumption of normal growth (15/24; 62.5%), and resolution of pulmonary hypertension (7/7; 100%, 2 patients unable to assess postoperatively). Two medically complicated patients died a few months after surgery unrelated to surgical complications. Four out of 8 ventilator-dependent patients were weaned from mechanical ventilation within 1 month after ASD closure. Closure of ASD did not improve those patients with highly advanced lung disease and/or medically complex conditions including underlying genetic abnormalities. Surgical complications were uncommon. Postoperative hospital stay was 4 to 298 days (median 8 days). The majority of our patients demonstrated significant clinical improvement after ASD closure. Early ASD closure is safe and beneficial for symptomatic infants and young children with associated underlying pulmonary abnormalities, especially bronchopulmonary dysplasia.

Favorable role of IDH1/2 mutations aided with MGMT promoter gene methylation in the outcome of patients with malignant glioma.

AIM: The implications of molecular biomarkers IDH1/2 mutations and MGMT gene promoter methylation were evaluated for prognostic outcome of glioma patients. MATERIALS & METHODS: Glioma cases were analyzed for IDH1/2 mutations and MGMT promoter methylation by DNA sequencing and methylation-specific PCR, respectively. RESULTS: Mutations found in IDH1/2 genes totaled 63.4% (N = 40) wherein IDH1 mutations were significantly associated with oligidendrioglioma (p = 0.005) and astrocytoma (p = 0.0002). IDH1 mutants presented more, 60.5% in MGMT promoter-methylated cases (p = 0.03). IDH1 mutant cases had better survival for glioblastoma and oligodendrioglioma (log-rank p = 0.01). Multivariate analysis confirmed better survival in MGMT methylation carriers (hazard ratio [HR]: 0.59; p = 0.031). Combination of both biomarkers showed better prognosis on temozolomide (p < 0.05). CONCLUSION: IDH1/2 mutations proved independent prognostic factors in glioma and associated with MGMT methylation for better survival.

Alveolar Soft Part Sarcoma Metastasizing to the Brain: A Rare Entity Revisited with Review of Recent Literature.

A 20-year-old male patient presented with a recent history of two episodes of seizures and Glasgow Coma Scale of E3V3M6. He was drowsy at presentation with bradycardia. On further examination, he was found to be having a 10 × 6cm well-circumscribed mass in the right medial thigh whose fine needle aspiration cytology was suggestive of soft tissue sarcoma. Contrast-enhanced magnetic resonance imaging brain showed enhancing lobulated lesions in bilateral hemispheres with significant edema. A decision to decompress the intracranial space occupying lesion was taken. Left-sided larger brain lesions underwent total gross excision followed by excision of the thigh mass. Histopathology of brain lesion was suggestive of metastatic deposits of alveolar soft part sarcoma, whereas the thigh mass was suggestive of alveolar soft part sarcoma grade 2 according to Fédération Nationale des Centres de Lutte Contre Le Cancer grading system. Postoperative course of the patient was unremarkable and his general condition improved remarkably (Functional Assessment of Cancer Therapy-Brain version 4 score improvement >50% at 1 month). He is in follow-up for the last 12 months and currently has completed chemoradiotherapy and is living a self-sufficient life. Though patients with aforementioned rare diagnosis have overall poor prognosis, decompressive craniotomy with metastasectomy may improve the overall quality of life of such young patients, and further chemoradiotherapy may help in prolonging life with acceptable level of comorbidity. This case is being discussed here in terms of the rarity of the final diagnosis, the management strategy used, and the quality of life improvement.

Pharmacokinetic evaluation, molecular docking and in vitro biological evaluation of 1, 3, 4-oxadiazole derivatives as potent antioxidants and STAT3 inhibitors.

1, 3, 4-Oxadiazole derivatives (4a-5f) were previously synthesized to investigate their anticancer properties. However, studies relating to their antioxidant potential and signal transducer and activator of transcription (STAT) inhibition have not been performed. We investigated previously synthesized 1, 3, 4-oxadiazole derivatives (4a-5f) for various radical scavenging properties using several in vitro antioxidant assays and also for direct inhibition of STAT3 through molecular docking. The data obtained from various antioxidant assays such as 2, 2,-diphenyl-1-picrylhydrazyl radical (DPPH), nitric oxide, hydrogen peroxide, and superoxide anion radical revealed that among all the derivatives, compound 5e displayed high antioxidant activities than the standard antioxidant L-ascorbic acid. Additionally, the total reduction assay and antioxidant capacity assay further confirmed the antioxidant potential of compound 5e. Furthermore, the molecular docking studies performed for all derivatives along with the standard inhibitor STX-0119 showed that binding energy released in direct binding with the SH2 domain of STAT3 was the highest for compound 5e (-9.91kcal/mol). Through virtual screening, compound 5e was found to exhibit optimum competency in inhibiting STAT3 activity. Compound 5e decreased the activation of STAT3 as observed with Western blot. In brief, compound 5e was identified as a potent antioxidant agent and STAT3 inhibitor and effective agent for cancer treatment.

Traumatic Vertebral Body Second Lumbar over Third Lumbar Retrolisthesis in a Child: Reporting the First Case along with the Review of Relevant Literature.

Traumatic retrolisthesis of the lumbar vertebrae is a rare entity in children. Only four such cases, two cases each of first lumbar-second lumbar (L1-L2) and L5-S1 retrolisthesis in children, have been reported so far in the English scientific literature. Here, we report a traumatic retrolisthesis of the L2 vertebra in an 8-year-old male child. He was injured when he lost control while playing, skidded, and fell into a 1-m deep drainage system hole. He presented with backache and urinary retention. His plain radiographs and noncontrast computed tomography of the lumbosacral spine revealed Meyerding Grade II retrolisthesis of the L2 vertebra over the third. The magnetic resonance imaging of the affected area revealed no significant canal narrowing, and there was no spinal cord compression or contusion. A urodynamic study was done which revealed a normal bladder function. The patient was given a trial of spontaneous urination by removing the Foley's catheter after 5 days of injury, and he passed urine normally. The patient was managed conservatively. He was discharged on day 7 with the advice of complete bed rest of 6 weeks and thoracolumbosacral orthoses. The patient has been in follow-up for the past 15 months, and his listhesis has completely resolved. The patient is ambulatory with no neurodeficit. This case is being presented in view of rarity. This is the first case report of L2 over L3 retrolisthesis in a child.

Evaluation of Role of Electrophysiological Studies in Patients with Lumbar Disc Disease.

BACKGROUND: The role of the electrophysiologic studies in peripheral nerves and muscles of lower limbs (including paraspinal muscles) in prolapsed lumbar intervertebral discs has been studied with equivocal results. Pre- and post-operative electrodiagnostic studies have not been compared much. AIMS AND OBJECTIVES: To study the role of the electrophysiologic studies in prolapsed lumbar/lumbosacral intervertebral discs for finding the association between clinical findings and electrophysiological changes and to compare the electrophysiologic studies pre- and post-operatively. MATERIALS AND METHODS: The study was conducted from July 2014 to June 2016 on fifty patients who were admitted in the department of neurological surgery with lumbar disc prolapse and all these patients were subjected to surgery. Both pre- and post-operative (from 1 to 6 months after surgery) electrophysiological studies were conducted and compared. RESULTS: As per the electromyographic (EMG) abnormalities, the most common levels of intervertebral disc prolapse were L4-L5 and L5-S1 accounting for 32% of cases each followed by L5-S1 level which was seen in 28% of patients with L2-L3, L3-L4, and L4-L5 prolapsed intervertebral disc (PIVD) and L3-L4 and L4-L5 PIVD were seen in 4% of cases each. Of the 50 patients, EMG findings correlated with operative findings in 37 (74%) patients, however operative findings did not correlate with EMG findings in 13 (26%) patients. CONCLUSION: In compressive lesions of nerve roots (due to disc prolapsed), the EMG method has a high degree of accuracy in determining not only the presence of such lesions but also their exact location. EMG is accurate when correlated with the operative findings.

Osteoporosis Presenting as Low Backache: An Entity not Uncommon to be Missed.

INTRODUCTION: Low backache (LBA) is highly prevalent in osteoporotic patients and affects their quality of life. Overall, osteoporosis incidence is greater in females than in males, and osteoporotic fractures typically occur with only modest or moderate trauma. AIMS AND OBJECTIVES: To evaluate osteoporosis as a cause of LBA in patients attending a neurosurgical outpatient department and to study various risk factors associated with it. MATERIALS AND METHODS: The study entitled "Osteoporosis presenting as LBA: An entity not uncommon to be missed" was a 2-year hospital-based study conducted from August 2014 to July 2016 in a prospective manner and included 100 patients of osteoporosis with LBA. Analysis of records included their chief complaints, signs and symptoms, diagnostic investigations performed, treatment modalities they underwent, and further recommended management carried on them. RESULTS: Out of total 100 patients evaluated, 33 (33%) were male and 67 (67%) were female; the age of patients was in the range of 35-70 years (mean 56.54 ± 91). The number of patients with a significant medical or surgical history was 31 (31%). The history of drug intake such as thyroxine, steroids, and antiepileptics was present in a total of 11 patients out of which 10 were female and one was male. Regarding lifestyle characteristics of studied patients, a total number of 72 (72%) were having sedentary habits with 15 (45.5%) males and 57 (85.1) females, the total number of moderate workers was 19 (27.3) males and 10 (14.9%) females, and heavy workers were 9 (9%) with 9 (27.3) males and 0 (0%) female. CONCLUSION: LBA is highly prevalent in osteoporotic patients especially in women. The incidence of osteoporosis and LBA increased with low body mass index, increasing age, and duration of menopause. The various risk factors for osteoporosis include smoking, history of medical diseases such as diabetes mellitus, history of hysterectomy, and history of antiepileptic, thyroxine, and steroid intake.

Antioxidant and apoptotic effects of Callistemon lanceolatus leaves and their compounds against human cancer cells.

Callistemon lanceolatus (Myrtaceae) has been utilized in folk medicine and its pharmacological properties are widely studied. Phytochemicals are effectively recognized as bases of pharmacologically potent drugs for the development of anticancer therapeutics. The free radical scavenging potential of numerous extracts of C. lanceolatus leaves, Hexane leaf extract (HLE), Chloroform leaf extract (CLE), Ethyl acetate leaf extract (ELE), Methanol leaf extract (MLE), and Aqueous leaf extract (ALE)) were determined by Biochemical assay. We evaluated the anticancer activity of C. lanceolatus leaves extracts against different human cancer cell lines viz liver cancer cells (HepG2), breast cancer cells (MCF7), and normal human embryonic kidney (HEK 293) cell line. The ELE and MLE extracts of C. lanceolatus leaves showed potential antiproliferative effects on HepG2 cells. On the basis of free radical scavenging potential and cytotoxicity studies, ELE and MLE extracts of C. lanceolatus leaves are further evaluated in detail for numerous biological activities. ELE and MLE extracts reduced the cell growth, ROS generation, lowering the potential of cell migration and inhibits the metastatic activity in HepG2 cell lines. ELE and MLE extracts treated HepG2 cells showed down-regulation of STAT3 and up-regulation of p53 and inhibition of cdk2 and cyclin A activity. Phytochemicals analysis have shown that the ELE and MLE possess some anticancer compounds like 4-Fluoro-2-trifluoromethylbenzoic acid, neopentyl ester; fumaric acid, di(pent-4-en-2-yl) ester; 2,3-Dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one and 2-Furancarboxaldehyde,5-(hydroxymethyl). Molecular docking results demonstrate that interactions of compounds present in ELE and MLE extracts with the SH2 domain of STAT3, might be responsible for their inhibitory effects. We have further concluded that the ELE and MLE extracts of C. lanceolatus arrests the cells at S and G2/M phase and subsequently induced cell death by regulating the DNA damage in HepG2 cells.

Role of Dual Energy X-ray Absorptiometry (DEXA) Scan in the Diagnosis of Chronic Low Back Pain - a Prospective Randomized Controlled Study in Osteoporotic Patients Hospitalized in a Tertiary Care Institute.

OBJECTIVES: Osteoporosis is a skeletal disorder characterized by a decrease in bone mass, with accompanying microarchitectural damage that increases the risk of bone fracture. The aim of this study is to evaluate various risk factors for osteoporosis and the role of DEXA scan in diagnosing the problem in an earlier stage. MATERIALS AND METHODS: About 100 patients who presented with complaint of low back pain in our outpatient department were studied and subjected to a DEXA scan. RESULTS: The age range of patients included in this study was between 35 and 70 years. Of all subjects, 85.10% (n=57) were females and 78.80% (n=26) males. The number of those with significant medical or surgical history was 31% (n=31). The anthropometric characteristics of the studied group included weight, height, and also BMI in kg/m2, which was 20.23, 21.06 in male subjects and 19.343, 20.42 in female ones. Regarding DEXA measurements, the bone mineral density was 0.97±0.27 (0.48, 1.96) for males and 0.83±0.21(0.01, 1.60) for females, with a total of 0.88±0.24 (0.01, 1.96). CONCLUSION: Low back pain is highly prevalent in postmenopausal women. DEXA is a widely accepted radiological tool used to detect osteoporotic changes in bones earlier, with a higher accuracy than plain radiographs of skeletal system. It is relatively cheap, needs no special preparation and involves less radiation hazard.

Pediatric Intracranial Hydatid Cyst: A Case Series with Literature Review.

Hydatid disease is an endemic zoonotic disease in many areas of the world. An intracranial hydatid cyst is a relatively rare entity, accounting for only 1-2% of all intracranial space-occupying lesions. Most commonly they are seen in children and young adults. Here, we present 9 cases of pediatric intracranial hydatid cyst operated at Sher-I-Kashmir Institute of Medical Sciences, Srinagar, India, between 2009 and 2015. The mean age of presentation was 11.5 years. The male to female ratio was 5: 4. In 7 cases, a history of contact with pet dogs was present. Seizure was the most common finding, present in 7 cases. Seven patients had solitary cysts and 2 had multiple cysts on presentation. All patients were operated on, and recurrence was observed in 2 patients. The features of this rare disease are retrospectively analyzed in this presentation and the literature is reviewed.

Concordant association validates MGMT methylation and protein expression as favorable prognostic factors in glioma patients on alkylating chemotherapy (Temozolomide).

O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation and its subsequent loss of protein expression has been identified to have a variable impact on clinical outcome of glioma patients indicated for chemotherapy with alkylating agents (Temozolomide). This study investigated methylation status of MGMT gene along with in situ protein expression in malignant glioma patients of different histological types to evaluate the associated clinical outcome vis-a-vis use of alkylating drugs and radiotherapy. Sixty three cases of glioma were evaluated for MGMT promoter methylation by methylation-specific PCR (MS-PCR) and protein expression by immunostaining (IHC). Methylation status of MGMT and loss of protein expression showed a very high concordant association with better survival and progression free survival (PFS) (p < 0.0001). Multivariate Cox regression analysis showed both MGMT methylation and loss of protein as significant independent prognostic factors in glioma patients with respect to lower Hazard Ratio (HR) for better OS and PFS) [p < 0.05]. Interestingly concordant MGMT methylation and lack of protein showed better response in TMZ therapy treated patient subgroups with HR of 2.02 and 0.76 (p < 0.05). We found the merits of prognostication of MGMT parameters, methylation as well as loss of its protein as predictive factors for favorable outcome in terms of better survival for TMZ therapy.
