Current Role Of Laser Interstitial Thermal Therapy In The Treatment Of Intracranial Tumors, Farhan A. Mirza, Rida Mitha, Muhammad Shahzad Shamim Dec 2020

Current Role Of Laser Interstitial Thermal Therapy In The Treatment Of Intracranial Tumors, Farhan A. Mirza, Rida Mitha, Muhammad Shahzad Shamim

Section of Neurosurgery

Laser interstitial thermal therapy (LITT) is gaining popularity in the treatment of both primary and secondary intracranial tumors. The goal of LITT is to deliver thermal energy in a predictable, controlled, and minimally invasive fashion. It can be particularly valuable in patients with recurrent tumors who, due to previous radiation or surgery, may have a potentially higher risk of wound breakdown or infection with repeat craniotomy. Deep-seated lesions that are often inaccessible through open approaches (thalamus, hypothalamus, mesial basal temporal lobe, brainstem) may also be suitable targets. The experience and data published thus far on this modality is limited but …

Childhood Medulloblastoma, Naureen Mushtaq, Shahzadi Resham, Muhammad Shahzad Shamim, Bilal Mazhar Qureshi, Quratulain Riaz, Eric Bouffet

Section of Haematology/Oncology

Medulloblastoma is the most common malignant brain tumour in children and is a major cause of mortality and morbidity, particularly in low- and middle-income countries. It has been risk-stratified on the basis of clinical (age, metastasis and extent of resection) and histological subtypes (classic, desmoplastic and anaplastic). However, recently medulloblastoma has been sub-grouped by using a variety of different genomic approaches, such as gene expression profiling, micro-ribonucleic acid profiling and methylation array into 4 groups, namely Wingless, Sonic hedgehog, Group 3 and Group 4. This new sub-grouping has important therapeutic and prognostic implications. After acute leukaemia, brain tumour is the …

Cerebellar Mutism Syndrome After Surgical Resection Of Posterior Fossa Neoplastic Lesions, Saqib Kamran Bakhshi, Rida Mitha, Naureen Mushtaq, Muhammad Shahzad Shamim

Section of Neurosurgery

Cerebellar Mutism Syndrome (CMS) is a well-described clinical entity that complicates surgeries for posterior fossa tumours; more so in children than adults. This review focuses on the current understanding of CMS, its incidence and risk factors. Incidence showed a variable range in retrospective studies due to variety of definitions. Risk factors can be classified as either modifiable including surgical technique, or non-modifiable which include tumour related factors. A positive correlation has been associated between tumour pathology, brain stem invasion and size of tumour at time of presentation with development of CMS.

Value Of Achieving A Watertight Dural Closure, And The Use Of Dural Sealants After Supratentorial Cranial Surgery, Ummey Hani, Fatima Aziz, Muhammad Shahzad Shamim Aug 2020

Value Of Achieving A Watertight Dural Closure, And The Use Of Dural Sealants After Supratentorial Cranial Surgery, Ummey Hani, Fatima Aziz, Muhammad Shahzad Shamim

Section of Neurosurgery

Dural closure at the end of cranial surgery is considered an extremely important step to maintain anatomical continuity, separate the intradural space with the extradural one, and to prevent possible complications related to cerebrospinal fluid leak. Wherein its usefulness in posterior fossa craniotomy is established, many surgeons do not perform it routinely in supratentorial craniotomies, citing unnecessary delay and lack of evidence supporting it. Herein, we have reviewed the data to find evidence in support of watertight suture based dural closures compared to other dural closure techniques, in supratentorial craniotomies.


Significance Of Micro-Rna Expression In Patients With Meningioma, Rida Mitha, Muhammad Shahzad Shamim Jul 2020

Significance Of Micro-Rna Expression In Patients With Meningioma, Rida Mitha, Muhammad Shahzad Shamim

Section of Neurosurgery

Recent brain tumour research has shown abnormalities in gene expression as key features for almost all common brain tumours investigated. However, there is increasing evidence that epigenetic abnormalities are also crucial for tumorigenesis. Epigenetic abnormalities are heritable alterations affecting gene expression without changing the primary DNA sequence. Epigenetic abnormalities in meningiomas include abnormal microRNA expression, altered DNA methylation and histone and chromatin modifications. In this review we identify the role of altered expression of microRNA in the development and recurrence of meningioma. Based on the review of current literature, extensive knowledge of micro-RNA expression cannot only determine tumour recurrence and …

Permanent Pre-Operative Cerebrospinal Fluid Diversion In Paediatric Patients With Posterior Fossa Tumours, Ummey Hani, Saqib Kamran Bakhshi, Muhammad Shahzad Shamim

Section of Neurosurgery

Management options for obstructive hydrocephalus in children with posterior fossa tumours have been debated upon throughout the course of neurosurgical practice. Permanent pre-operative CSF diversion via ventricular shunts or endoscopic third ventriculostomy have been employed to prevent the possible persistence of hydrocephalus after tumour removal, but is considered unnecessary and even dangerous amongst a large group of neurosurgeons. In this paper, we have reviewed the literature for the merits and demerits of pre-operative permanent CSF diversion in paediatric patients presenting with posterior fossa tumours.
