Significant Effect of Anti-tyrosine Kinase Inhibitor (Gefitinib) on Overall Survival of the Glioblastoma Multiforme Patients in the Backdrop of Mutational Status of Epidermal Growth Factor Receptor and PTEN Genes.

INTRODUCTION: We aimed to assess the effect of anti-tyrosine kinase inhibitors (TKIs) (gefitinib) in overall survival (OS) of the glioblastoma multiforme (GBM) patients in the backdrop of mutational status of epidermal growth factor receptor (EGFR) and PTEN genes. MATERIALS AND METHODS: All the patients subjected to resection or biopsies were put on gefitinib, and radiotherapy was delivered as per the hospital protocol. EGFR and PTEN mutational spectrum was performed by single-strand conformation polymorphism followed by DNA sequencing. RESULTS: In total, 50% GBM tumors had mutation either in EGFR or PTEN. Median progression-free survival (PFS) and OS observed in patients with EGFR +ve/PTEN -ve were significantly favorable (P < 0.05) which aggregated to 9(7, 11) months and 20 (16, 24) months, respectively, than 6 (4, 8) months and 13 (7, 19) months in patients with PTEN +ve/EGFR -ve. Patients positive for both EGFR/PTEN had lower disease-free survival and OS of 6 and 9 months as compared to 6 (5, 7) and 14 (12, 24) months for those negative for both EGFR/PTEN. CONCLUSIONS: We conclude that EGFR gene alterations with wild-type PTEN are associated with significantly better PFS and OS in patients treated with anti-TKIs (gefitinib). Combined EGFR and PTEN gene mutation is associated with significantly poor response to gefitinib in terms of median OS.

Pediatric Head Injury: A Study of 403 Cases in a Tertiary Care Hospital in a Developing Country.

INTRODUCTION: Traumatic brain injury (TBI) in children is a significant cause of morbidity and mortality worldwide. Falls are the most common type of injury, followed by motor vehicle-related accidents and child abuse. AIMS AND OBJECTIVES: The aim and objective of this study was to elucidate the various modes of injury, prognostic factors, complications, incidence of various modes of injury, and outcome in TBI in pediatric population. MATERIALS AND METHODS: Patients with TBI, 18 years or less in age, managed in our Department of Neurosurgery, over a period of 2 years, were studied prospectively. Detailed history, general physical examination, systemic examination, and central nervous system examination including assessment of Glasgow Coma Scale score (GCS) and pupillary size and reaction were noted in every patient. Based on GCS, patients were divided into mild head injury (GCS 13-15), moderate head injury (GCS 9-12), and severe head injury (GCS ≤8) categories. All the patients were subjected to plain computed tomography (CT) scan head, and CT findings were noted. Patients were managed conservatively or surgically as per the standard indications. The outcome of all these patients was assessed by Glasgow outcome scale and divided into good (normal, moderate disability) and poor (severe, vegetative, dead) outcome. Outcome was assessed in relation to age, sex, GCS, pupil size and reaction, CT scan features, intervention, and associated injuries. RESULTS: A total of 403 patients aged between 1 day and 18 years were included in the study comprising 252 males (63%) and 151 females (37.75%). The common modes of injury were fall 228 (56.6%) followed by road traffic accidents 138 (34.2%), assault 10 (2.5%), and others 27 (6.7%) which include sports injury, hit by some object on head, and firearm injury. Majority of our patients had a GCS of 13-15 (mild head injury), 229 (57.3%), followed by 9-12 (moderate head injury) 119 (29.8%), followed by 8 or less (severe head injury) 52 (13%). In group of patients in the category of GCS ≤ 8, poor outcome was seen in 65.3%, followed by patients in group GCS 9-12 at 2.45% succeeded by group of patients with GCS 13-15 at 2.6%, which was statistically significant (P < 0.0001). A total of 354 (87.8%) patients had normal pupils, 37 (9.2%) had anisocoria, and 12 (3%) patients had fixed dilated pupils. Fixed dilated pupil had poor outcome (100%) followed by anisocoria (40.5%) and normal pupils (16%), which was statistically significant (P < 0.0001). CONCLUSION: Majority of children who suffer from TBI do well although it still continues to be a significant cause of morbidity and mortality in them. The outcome is directly related to the neurological status in which they present to the hospital.

Epidemiology of the neural tube defects in Kashmir Valley.

INTRODUCTION/BACKGROUND: Neural tube defects (NTD) are the most common congenital malformations affecting the brain and spinal cord and have a multifactorial etiology. Genetic and environmental factors have been found to cause these defects, both individually and in combination. AIMS AND OBJECTIVES: The aim of this study was to determine the incidence, types, demographics, risk factors, and other associated anomalies relevant to NTDs in Kashmir Valley. MATERIALS AND METHODS: A 2-year hospital-based prospective study was carried out from November 2013 to October 2015. A detailed history of the mother was taken along with detailed clinical examination of neonate including measurement of head circumference and checking the status of fontanella, whether - lax/full/bulging/or tense, type of NTD. Investigations that were done included were X-ray skull: Anteroposterior (AP) and lateral, X-ray spine: AP and lateral, ultrasonography abdomen, magnetic resonance imaging: Spine and brain. RESULTS: The total number of babies with NTD's was 125 with an overall incidence of 0.503. District Kupwara was having the highest incidence (1.047) and district Srinagar the lowest incidence of NTD's (0.197). The majority of NTD's (116 cases, 92.8%) were found in the rural areas. Among the different types of NTD's, spina bifida had an incidence of 0.342 (85 cases, 68%), and anencephaly had an incidence of 0.113 (28 cases, 22.4%). There was a slight preponderance of females over males with NTD's. There were70 females (56%) and 55 males (44%) respectively with a male:female ratio of 0.8:1. CONCLUSIONS: The incidence rates of NTDs are very high for Kashmir Valley. Geographical distribution of NTDs at this place confirms a relationship between the socioeconomic status, educational status, maternal age and environmental factors for the development of an NTD. The results of this study point to the importance establishing a health policy to prevent NTDs in Kashmir Valley.

Role of albendazole in the management of hydatid cyst liver.

BACKGROUND/AIM: Hydatidosis has a worldwide distribution and the liver is the most common organ involved. Hydatid cysts of the liver can be managed either by nonoperative or operative methods. Nonoperative methods include chemotherapy and percutaneous treatment. The study aimed at understanding the effect of albendazole therapy on the viability of protoscoleces and recurrence rate of hydatid disease of the liver. PATIENTS AND METHODS: The study was conducted at Sher-i-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, India, over a period of 2 years from January 2002 to December 2003, with further follow-up of 5 years. The study included 72 cases in the age group of 17-66 years, comprising 39 males and 33 females. The patients were randomized into two groups of 36 patients each. In group A, patients were directly subjected to surgery, while in group B, patients were administered albendazole for 12 weeks preoperatively, followed by a further postoperative course for 12 weeks. RESULTS: Of patients who received albendazole therapy, no patient had viable cysts at the time of surgery, as compared to 94.45% of the patients who did not receive any preoperative albendazole (P<0.01). In patients who did not receive any albendazole therapy, recurrence rate was 16.66%, while no recurrence was seen in patients who received albendazole therapy (P≤0.05). CONCLUSION: We conclude that albendazole is an effective adjuvant therapy in the treatment of hydatid liver disease.

Albendazole as an adjuvant to the standard surgical management of hydatid cyst liver.

BACKGROUND: The treatment options for hydatid cyst liver include non-operative and operative methods. Operative methods include conservative and radical procedures. Non-operative methods include chemotherapy and percutaneous treatment of liver hydatidosis. MATERIAL AND METHODS: The study was conducted at Sher-i-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, India, over a period of two years from March 2001 to February 2003 with further follow-up of 5-6 years. The study included 64 cases in the age group of 15 years to 64 years, comprising 36 males and 28 females. The aim of the study was to know the effect of preoperative and postoperative albendazole therapy on the viability of protoscolices and recurrence rate of hydatid disease of liver. Patients were divided into four group of 16 each. In group A, patients were directly subjected to surgery. In group B, patients were given albendazole for 8 weeks followed by surgery. In group C, patients were given albendazole for 8 weeks preoperatively followed by further postoperative course for 8 weeks. In group D, patients were first taken for surgery followed by postoperative course of albendazole for 8 weeks. RESULTS: Out of those patients who received preoperative albendazole only 9.37% had viable cysts at the time of surgery as compared to 96.87% of patients who did not receive any preoperative albendazole. In those patients who did not receive any albendazole therapy, recurrence rate was 18.75% whereas recurrence was 4.16% in patients who received albendazole therapy. CONCLUSION: We conclude that albendazole is safe and effective adjuvant therapy in the treatment of hydatid liver disease.
