Cost and outcomes of routine HIV care and treatment: public and private service delivery models covering low-income earners in South Africa.

BACKGROUND: While South Africa's national HIV program is the largest in the world, it has yet to reach the UNAIDS 95-95-95 targets. To reach these targets, the expansion of the HIV treatment program may be accelerated through the use private sector delivery models. This study identified three innovative non-governmental primary health care models (private sector) providing HIV treatment, as well as two government primary health clinics (public sector) that served similar populations. We estimated the resources used, and costs and outcomes of HIV treatment across these models to provide inputs to inform decisions around how these services might best be provided through National Health Insurance (NHI). METHODS: A review of potential private sector models for HIV treatment in a primary health care setting was conducted. Models actively offering HIV treatment (i.e. in 2019) were considered for inclusion in the evaluation, subject to data availability and location. These models were augmented by government primary health clinics offering HIV services in similar locations. We conducted a cost-outcomes analysis by collecting patient-level resource usage and treatment outcomes through retrospective medical record reviews and a bottom-up micro-costing from the provider perspective (public or private payer). Patient outcomes were based on whether the patient was still in care at the end of the follow up period and viral load (VL) status, to create the following outcome categories: in care and responding (VL suppressed), in care and not responding (VL unsuppressed), in care (VL unknown) and not in care (LTFU or deceased). Data collection was conducted in 2019 and reflects services provided during the 4 years prior to that (2016-2019). RESULTS: Three hundred seventy-six patients were included across the five HIV treatment models. Across the three private sector models there were differences in the costs and outcomes of HIV treatment delivery, two of the models had results similar to the public sector primary health clinics. The nurse-led model appears to have a cost-outcome profile distinct from the others. CONCLUSION: The results show that across the private sector models studied the costs and outcomes of HIV treatment delivery vary, yet there were models that provided costs and outcomes similar to those found with public sector delivery. Offering HIV treatment under NHI through private delivery models could therefore be an option to increase access beyond the current public sector capacity.

Acceptability, feasibility and cost of point of care testing for sexually transmitted infections among South African adolescents where syndromic management is standard of care.

BACKGROUND: Young people (YP) in southern Africa are at substantial risk of HIV and sexually transmitted infections (STIs). Despite the epidemiological and biological link between STIs and HIV transmission and acquisition, infections such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) remain widely undiagnosed. Syndromic STI management is the standard of care in low- and middle-income countries (LMICs) despite a high prevalence of asymptomatic infections. We conducted an observational study to explore the acceptability, feasibility, and cost of a STI test-and-treat service for YP in Cape Town. METHODS: YP attending a mobile clinic (MC) and a youth centre clinic (YC) were offered STI screening. Urine testing for CT and NG using a 90-min molecular point-of-care (POC) test on the GeneXpert platform was conducted and treatment provided. Data were collated on demographics, sexual behaviour, presence of symptoms, uptake of same-day treatment, prevalence of CT/NG, and service acceptability. RESULTS: Three hundred sixty six participants were enrolled (median age 20, 83% female).57% (209/366) of participants tested positive for either CT (126/366, 34%) or NG (57/366, 16%) or co-infection (26/366, 7%). Clinical symptoms were a poor predictor of GeneXpert diagnosed CT or NG, with a sensitivity of 46.8% and 54.0% for CT and NG respectively. Although half of participants initially chose to receive same day results and treatment, only a third waited for results on the day. The majority of participants (91%) rated the service highly via a post-visit acceptability questionnaire. CONCLUSION: Curable STIs are highly prevalent in this population. STI screening using POC testing was feasible and acceptability was high. The study provides further impetus for moving policy beyond syndromic management of STIs in South Africa.

Primary healthcare seeking behaviour of low-income patients across the public and private health sectors in South Africa.

BACKGROUND: The proposed National Health Insurance (NHI) system aims to re-engineer primary healthcare (PHC) in South Africa, envisioning both private sector providers and public sector clinics as independent contracting units to the NHI Fund. In 2017, 16% of the South African population had private medical insurance and predominately utilised private providers. However, it is estimated that up to 28% of the population access private PHC services, with a meaningful segment of the low-income, uninsured population paying for these services out-of-pocket. The study objective was to characterise the health seeking behaviour of low-income, patients accessing PHC services in both the public and private sectors, patient movement between sectors, and factors influencing their facility choice. METHODS: We conducted once-off patient interviews on a random sample of 153 patients at 7 private PHC providers (primarily providing services to the low-income mostly uninsured patient population) and their matched public PHC clinic (7 facilities). RESULTS: The majority of participants were economically active (96/153, 63%), 139/153 (91%) did not have health insurance, and 104/153 (68%) earned up to $621/month. A multiple response question found affordability (67%) and convenience (60%) were ranked as the most important reasons for choosing to usually access care at public clinics (48%); whilst convenience (71%) and quality of care (59%) were key reasons for choosing the private sector (32%). There is movement between sectors: 23/76 (30%) of those interviewed at a private facility and 8/77 (10%) of those interviewed at a public facility indicated usually accessing PHC services at a mix of private and public facilities. Results indicate cycling between the private and public sectors with different factors influencing facility choice. CONCLUSIONS: It is imperative to understand the potential impact on where PHC services are accessed once affordability is mitigated through the NHI as this has implications on planning and contracting of services under the NHI.

Population-based cancer screening programmes in low-income and middle-income countries: regional consultation of the International Cancer Screening Network in India.

The reductions in cancer morbidity and mortality afforded by population-based cancer screening programmes have led many low-income and middle-income countries to consider the implementation of national screening programmes in the public sector. Screening at the population level, when planned and organised, can greatly benefit the population, whilst disorganised screening can increase costs and reduce benefits. The International Cancer Screening Network (ICSN) was created to share lessons, experience, and evidence regarding cancer screening in countries with organised screening programmes. Organised screening programmes provide screening to an identifiable target population and use multidisciplinary delivery teams, coordinated clinical oversight committees, and regular review by a multidisciplinary evaluation board to maximise benefit to the target population. In this Series paper, we report outcomes of the first regional consultation of the ICSN held in Agartala, India (Sept 5-7, 2016), which included discussions from cancer screening programmes from Denmark, the Netherlands, USA, and Bangladesh. We outline six essential elements of population-based cancer screening programmes, and share recommendations from the meeting that policy makers might want to consider before implementation.

Impact of surgery, adjuvant treatment, and other prognostic factors in the management of anaplastic ganglioglioma.

BACKGROUND/PURPOSE: Anaplastic ganglioglioma (AGG) is a rare tumor with both glial and neuronal component accounting for less than 1% of all CNS tumors with limited information about the optimum treatment and outcome of these tumors. METHOD AND MATERIALS: We did a thorough search of the PubMed with the following MesH terms: "Ganglioglioma; Anaplastic ganglioglioma; Ganglioglioma AND treatment; and Anaplastic ganglioglioma AND survival" to find all possible publications related to AGG to perform an individual patient data analysis and derive the survival outcome and optimum treatment of these tumors. RESULTS: A total of 56 articles were retrieved pertaining to AGG with 88 patients. However, a total of 40 publications found eligible with 69 patients for individual patient data analysis. Median age for the entire cohort was 16 years (range 0.2-77 years). Surgical details were available for 64 patients. A gross total or near total resection was reported in 21 cases (32.8%), subtotal resection or debulking was reported in 25 cases (39.1%). Surgical details were available for 64 patients. A gross total or near total resection was reported in 21 cases (32.8%), and subtotal resection or debulking was reported in 25 cases (39.1%). Median overall survival (OS) was 29 months [95% CI 15.8-42.2 months] with 2- and 5-year OS 61 and 39.4% respectively. CONCLUSION: AGG is associated with a dismal. Pediatric age and a gross total resection of tumor confer a better progression-free survival and OS. Hence, surgery should remain the cornerstone of therapy. However, because of modest survival, there is enough opportunity to improve survival with addition of adjuvant radiation and chemotherapy. A whole genome sequencing and molecular characterization would help to derive the best treatment option.

Bilateral clavicular attachment of omohyoid muscle.

Omohyoid muscle present in cervical region is of particular importance to anatomists as it defines anteriorly the carotid triangle and divides the posterior cervical triangle. It has superior and inferior bellies and an intermediate common tendon. Like sternohyoid, sternothyroid and thyrohyoid muscles, omohyoid is also an infrahyoid muscle, but it differs from them in its course. The infrahyoid muscles are formed from a muscle primordium occurring in the anterior cervical area. Anderson (Anderson, 1881) theorized that the superior belly of the omohyoid muscle is a true infrahyoid muscle, whereas the inferior belly most likely shares a common embryology with the subclavius muscle. In the present study, during routine dissection in the neck region of an adult male cadaver of 50 years age, an anomalous origin of inferior belly of omohyoid with absence of intermediate tendon was observed bilaterally. It was arising from clavicle on both sides. Both the muscle bellies were measured from the lateral end of fascial sling. The inferior belly of omohyoid extending from the lateral margin of sling to clavicular surface was measured 3.3cm in length on left side and 3.6cm on right side. The omohyoid is important in neck dissections because it is considered as an ideal landmark for level III and IV lymph node metastases. Knowledge of variations of this muscle is very important for surgeries in neck region because of its close relation to the internal jugular vein and brachial plexus. Its crucial relationship to vascular structures in the neck makes it an important landmark during neck surgeries.

Radiation induced oral mucositis: a review of current literature on prevention and management.

Oral mucositis (OM) is a major limiting acute side effect of radiotherapy for head and neck cancer. The spectrum of problems associated with mucositis includes oral pain, odynophagia, reduced oral intake, and secondary infections. Incidence of mucositis is increased with addition of concurrent chemotherapy as well as altered fractionation schedules. This leads to treatment interruption and suboptimal disease control. Hence, prevention as well as timely management of OM is necessary for optimum tumor control. We reviewed the English literature with key words "Radiation induced mucositis, Mucositis, Oral Mucositis" to find relevant articles describing incidence, pathophysiology, prophylaxis, and treatment of oral mucositis. Prevention and treatment of OM is an active area of research. Maintenance of oral hygiene is an important part in prevention of OM. A battery of agents including normal saline and alkali (soda bicarbonate) mouth washes, low level laser therapy, and benzydamine (non-steroidal analgesic and anti-inflammatory) have effectiveness in the prevention and treatment of radiation induced oral mucositis. Chlorhexidine mouth gargles are recommended for prevention of chemotherapy induced oral mucositis but is not recommended for radiotherapy associated mucositis. Treatment of co-existing infection is also important and both topical (povidone iodine) and systemic anti fungals should be used judiciously. Radiation induced oral mucositis is a common problem limiting the efficacy of radiation by increasing treatment breaks. Adequate prophylaxis and treatment may limit the severity of radiation mucositis and improve compliance to radiation which may translate in better disease control and survival.

Level of Awareness of Various Aspects of Lung Cancer Among College Teachers in India: Impact of Cancer Awareness Programmes in Prevention and Early Detection.

Lung cancer is one of the most common causes of cancer mortality among men in India and incidence is increasing, but actually, they are largely preventable diseases. In India, advanced stage at the time of presentation is responsible for high mortality and morbidity and early detection is the only way to reduce it. The purpose of this study is to know the level of awareness of various aspects of lung cancer among college teachers and impact of awareness programmes in its prevention and early detection. This assessment was part of Pink Chain Campaign-a campaign on cancer awareness. During the cancer awareness events in 2011-2013 at various women colleges in different parts in India, pre-test related to lung cancer was followed by awareness programme. Post-test using the same questionnaire was conducted at the end of interactive session, at 6 months and 1 year. A total of 872 out of 985 teachers participated in the study (overall response rate was 88.5 %). Mean age of the study population was 41.6 years (range 26-59 years). There was a significant increase in the level of knowledge regarding lung cancer at 6 months, and this was sustained at 1 year. Among teachers who were just asked yes or no question, 117 teachers (13.4 %) were smokers and 241 teachers (27.6 %) were alcoholics. Magazines and newspapers were sources for knowledge in 50-60 % of teachers, whereas approximately 30 % of teachers were educated by TV and Internet regarding various aspects of lung cancer. Post awareness at 6 months and 1 year, Pink Chain Campaign was the major source of knowledge related to lung cancer in more than 90 % of teachers by continuous and timely update on subject. Post awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons for not going for check-up were ignorance (83.1 %), fear (30.1 %) and lethargic attitude (29.3 %) initially, but over time, lack of time, lethargic attitude and hesitation became important factors after knowing various aspects of lung cancer. Knowledge of lung cancer was very low among teachers. Overall awareness of risk factors, sign and symptoms, screening modalities of lung cancer has improved in a year along with practices related to smoking and alcohol, but there was not much improvement in people undergoing regular check-ups. To inculcate safe practices in the lifestyle of people, awareness programmes such as the Pink Chain Campaign should be conducted more widely and frequently.

Report from a symposium on catalyzing primary and secondary prevention of cancer in India.

PURPOSE: Oral, breast, and cervical cancers are amenable to early detection and account for a third of India's cancer burden. We convened a symposium of diverse stakeholders to identify gaps in evidence, policy, and advocacy for the primary and secondary prevention of these cancers and recommendations to accelerate these efforts. METHODS: Indian and global experts from government, academia, private sector (health care, media), donor organizations, and civil society (including cancer survivors and patient advocates) presented and discussed challenges and solutions related to strategic communication and implementation of prevention, early detection, and treatment linkages. RESULTS: Innovative approaches to implementing and scaling up primary and secondary prevention were discussed using examples from India and elsewhere in the world. Participants also reflected on existing global guidelines and national cancer prevention policies and experiences. CONCLUSIONS: Symposium participants proposed implementation-focused research, advocacy, and policy/program priorities to strengthen primary and secondary prevention efforts in India to address the burden of oral, breast, and cervical cancers and improve survival.

Intradural extra medullary hemangiopericytoma of dorsal spine.

PURPOSE: Spinal hemangiopericytoma is a rare neoplasm that behaves similar to intracranial hemangiopericytoma, with approximately 60 cases being reported in the literature of which only 10 are located in the intradural extramedullary (IDEM) location. METHODS: We report a rare case of recurrent IDEM hemangiopericytoma of dorsal spine in a 16-year-old boy treated with surgery and adjuvant radiotherapy. RESULTS: Patient is disease free at 5 years posttreatment with residual neurological deficit, but is able to carry out his activities of daily living. CONCLUSION: Gross total resection, if feasible, followed by radiotherapy is the initial treatment of choice as radiotherapy improves recurrence free survival as well as overall survival.

Malignant peripheral nerve sheath tumour of penis.

Malignant peripheral nerve sheath tumour (MPNST) is a rare variety of soft tissue sarcoma that originates from Schwann cells or pluripotent cells of neural crest origin. They have historically been difficult tumours to diagnose and treat. Surgery is the mainstay of treatment with a goal to achieve negative margins. Despite aggressive surgery and adjuvant therapy, the prognosis of patients with MPNST remains poor. MPNST arising from penis is a very rare entity; thus, it presents a diagnostic and therapeutic challenge. We present a case of penile MPNST in a 38-year-old man in the absence of neurofibromatosis treated with surgery followed by post-operative radiotherapy to a dose of 60 Gray in 30 fractions and adjuvant chemotherapy with ifosfamide and adriamycin.

Molecular biomarkers involved in the progression of gallbladder inflammatory lesions to invasive cancer: A proteomic approach.

The progression of gallbladder inflammatory lesions to invasive cancer remains poorly understood, necessitating research on biomarkers involved in this transition. This study aims to identify and validate proteins associated with this progression, offering insights into potential diagnostic biomarkers for gallbladder cancer (GBC). Label-free liquid chromatography assisted tandem mass spectrometry (LC-MS/MS) proteomics was performed on samples from 10 cases each of GBC and inflammatory lesions, with technical duplicates. Validation was conducted through the enzyme-linked immunosorbent assay (ELISA) using 80 samples (40 GBC and 40 inflammatory lesions). Bioinformatics tools analyzed protein-protein interaction (PPI) networks and pathways. Statistical correlations with clinicopathological variables were assessed. Prognostic evaluation utilized Kaplan-Meier survival analysis and Cox regression analyses. mRNA expressions were studied using real time-polymerase chain reaction (RT-PCR). Out of 5,714 proteins analyzed, 621 were differentially expressed. Three upregulated (the S100 calcium-binding protein P [S100P], polymeric immunoglobulin receptor [PIGR], and complement C1q-binding protein [C1QBP]) and two downregulated (transgelin [TAGLN] and calponin 1 [CNN1]) proteins showed significant expression. Pathway analysis implicated involvement of proteoglycans in cancer and glycosaminoglycan metabolism. Significant correlations were observed between protein concentrations and clinicopathological variables. Prognostic factors such as tumor size, lymph node metastasis, and preoperative bilirubin levels were associated with overall survival. Protein-based assays demonstrated higher resolution compared to mRNA analysis, suggesting their utility in GBC risk stratification. S100P, PIGR, C1QBP, TAGLN, and CNN1 emerge as potential protein-based biomarkers involved in the progression from gallbladder inflammatory lesions to invasive cancer. These findings hold promise for improved diagnostic and prognostic strategies in GBC management.

Genomic landscape of gallbladder cancer: insights from whole exome sequencing.

BACKGROUND: Gallbladder carcinoma (GBC) is a common gastrointestinal malignancy noted for its aggressive characteristics and poor prognosis, which is mostly caused by delayed detection. However, the scarcity of information regarding somatic mutations in Indian patients with GBC has hampered the development of efficient therapeutic options. In the present study, we attempted to bridge this gap by revealing the mutational profile of GBC. MATERIALS AND METHODS: To evaluate the somatic mutation profile, whole exome sequencing (WES) was performed on 66 matched tumor and blood samples from individuals with GBC. Somatic variant calling was performed using GATK pipeline. Variants were annotated at pathogenic and oncogenic levels, using ANNOVAR, VEP tools and the OncoKB database. Mutational signature analysis, oncogenic pathway analysis and cancer driver genes identification were performed at the functional level by using the maftools package. RESULTS: Our findings focused on the eight most altered genes with pathogenic and oncogenic mutations: TP53, SMAD4, ERBB3, KRAS, ARID1A, PIK3CA, RB1, and AXIN1. Genes with pathogenic single nucleotide variations (SNVs) were enriched in oncogenic signaling pathways, particularly RTK-RAS, WNT, and TP53 pathways. Furthermore, our research related certain mutational signatures, such as cosmic 1, cosmic 6, and cosmic 18, 29, to known characteristics including patient age and tobacco smoking, providing important insights into disease etiology. CONCLUSIONS: Given the scarcity of exome-based sequencing studies focusing on the Indian population, this study represents a significant step forward in providing a framework for additional in-depth mutational analysis. Genes with substantial oncogenic and pathogenic mutations are promising candidates for developing targeted mutation panels, particularly for GBC detection.

Indigenously developed multipurpose acrylic head phantom for verification of IMRT using film and gel dosimetry.

The purpose of this study was to validate the newly designed acrylic phantom for routine dosimetric purpose in radiotherapy. The phantom can be used to evaluate and compare the calculated dose and measured dose using film and gel dosimetric methods. In this study, a doughnut-shaped planning target volume (8.54 cm3) and inner organ at risk (0.353 cm3) were delineated for an IMRT test plan using the X-ray CT image of the phantom. The phantom consists of acrylic slabs which are integrated to form a human head with a hole in the middle where several dosimetric inserts can be positioned for measurement. An inverse planning with nine coplanar intensity-modulated fields was created using Pinnacle TPS. For the film analysis, EBT2 film, flatbed scanner, in-house developed MATLAB codes and ImageJ software were used. The 3D dose distribution recorded in the MAGAT gel dosimeter was read using a 1.5 T MRI scanner. Scanning parameters were CPMG pulse sequence with 8 equidistant echoes, TR = 5600, echo step = 22 ms, pixel size = 0.5 × 0.5, slice thickness = 2 mm. Using a calibration relationship between absorbed dose and spin-spin relaxation rate (R2), R2 images were converted to dose images. The dose comparison was accomplished using in-house MATLAB-based graphical user interface named "IMRT3DCMP". For gel measurement dose grid from the TPS was extracted and compared with the measured dose grid of the gel. Gamma index analysis of film measurement for the tolerance criteria of 2%/2mm, 1%/1 mm showed more than 90% voxels pass rate. Gamma index analysis of 3D gel measurement data showed more than 90% voxels pass rate for different tolerance criteria of 2%/2 mm and 1%/1 mm. Overall both 2D and 3D measurement were in close agreement with the Pinnacle TPS calculated dose. The phantom designed is cost-effective and the results are promising, but further investigation is required to validate the phantom with other 3D conformal techniques for dosimetric purpose.

Clinico-embryological submission of an unilateral anomalous presentation of axillary artery.

OBJECTIVES: Descriptions of the variant arterial pattern of upper limb are not exceptional and are therefore frequently reported in anatomy archives. BACKGROUND: A noteworthy deviation from the usual branching pattern was observed unilaterally in a single cadaver. This unique division of axillary artery (AA) was present on the right side in an adult human cadaver of Indian origin. RESULTS: The first part of axillary artery gave off the superior thoracic and thoraco-acromial arteries. Just proximal to the upper border of pectoralis minor the AA was observed to divide into two trunks a medial and a lateral. The lateral trunk continued into the brachium as the usual axillary artery where as the medial trunk displayed the other branches deep and distal to the pectoralis minor muscle. The remarkable feature was the wide caliber of the axillary artery where it bifurcated into two branches. An attempt has been made to dwell upon the embryological basis of the present anomaly. CONCLUSIONS: The relevance of anomalous arterial pattern of upper limb (U.L.) is realized while performing percutaneous arterial venous catheter insertion into subclavian vein via the infraclavicular route. We advocate a meticulous familiarization of the anatomy of axillary artery and its topographical relationship to other neurovascular structures for the operating plastic surgeon, anesthetist and radiologist (Fig. 1, Ref. 12).

Leveraging epigenetics to enhance the efficacy of cancer-testis antigen: a potential candidate for immunotherapy.

Ovarian cancer is the most lethal gynecological malignancy in women. The phenotype is characterized by delayed diagnosis, recurrence and drug resistance. Inherent immunogenicity potential, oncogenic function and expression of cancer-testis/germline antigen (CTA) in ovarian cancer render them a potential candidate for immunotherapy. Revolutionary clinical findings indicate that tumor antigen-mediated T-cell and dendritic cell-based immunotherapeutic approaches provide an excellent strategy for targeting tumors. Currently, dendritic cell vaccination for the treatment of B-cell lymphoma and CTA-based T-cell receptor transduced T-cell therapy involving MAGE-A4 and NY-ESO-1 are well documented and shown to be effective. This review highlighted the mechanical aspects of epigenetic drugs that can elicit a CTA-based humoral and cellular immune response and implicate T-cell and dendritic cell-based immunotherapeutic approaches.

Despite substantial advancements in prognosis and diagnostic approaches, epithelial ovarian cancer is still the most lethal gynecological malignancy worldwide. In addition to radiotherapy, chemotherapy, hormonal therapy, and surgery, immunotherapy in the clinical setting is promising. Tumor-restricted expression and strong immunogenic potential make cancer-testis/germline antigen (CTA) a potential candidate for efficient T-cell and dendritic cell-mediated cancer immunotherapy. The expression of CTAs is shown to be modulated by a specific epigenetic fine-tuning mechanism. However, the expression and role of CTA in epithelial ovarian cancer immunotherapy are poorly understood. Therefore, in the current work, the authors thoroughly highlight and explore the possible epigenetic mechanisms associated with CTA expression and their implication in T-cell and dendritic cell-based immunotherapy approaches to ovarian cancer. Understanding such a paradigm is essential to adopting a precision medicine approach for better therapeutic options.

Development of serratiopeptidase and metronidazole based alginate microspheres for wound healing.

The objective of this study was to establish an effective therapy system for wound management. The present work describes preparation of metronidazole/serratiopeptidase loaded alginate microspheres by emulsification method. In vitro characterizations like particle size analysis, % yield, % encapsulation, and in vitro release were carried out. Wound healing assessment was determined by physical, histological, and biochemical methods. Wound healing performance of experimental formulations was compared with marketed product in rabbits. Result obtained for alginate microspheres showed good loading efficiency with spherical in shape. Experimentation suggests wound healing is improved by using serratiopeptidase and metronidazole in full thickness wounds in rabbits.

Accessory muscle belly of peroneus tertius in the leg--a rare anatomical variation with clinical relevance--utility in reconstructions.

We report here a rare muscular anomaly of the lower leg in an adult male cadaver observed during routine cadaveric dissection. Peroneus tertius (PT) is peculiar to man, being a hallmark of bipedal locomotion and erect posture. During the course of gross anatomy dissection, a rare finding of accessory belly of PT muscle was discovered. A meticulous dissection was performed and the observations were noted. The PT displayed two distinct bellies of origin. Both the bellies were substantial in size and were eventually fused close to their insertion at the base of the fifth meta-tarsal bone. Innervation of both the bellies was derived from the deep peroneal nerve. Soft tissue defects of the leg may be effectively covered by local muscles in the vicinity of the wounds. PT has been reliably used in the past for local transposition flaps in the lower extremities. The relations of the superficial nerve and the PT during placement of the anterolateral portal in ankle arthroscopy are vital to avoid inadvertent neuromuscular injuries. The presence of two bellies of the PT muscle has been discussed in the comparative perspective. A precise and detailed knowledge of the anatomical details of the crural muscles is important for performing reconstructive surgeries.

Glioblastoma with Primitive Neuroectodermal Component Treated with Adjuvant Radiotherapy and Temozolomide: A Pooled Analysis of 23 Patients.

AIM: Glioblastoma (GBM) is one of the most aggressive neoplasms of the central nervous system with dismal survival. In recent years, different variants of GBM have been described in the literature. GBM with areas of neuroectodermal differentiation (GBM-PNET) is a relatively new entity in GBM. Presence of the neuroectodermal component increases the propensity of systemic dissemination as with other intracranial primitive neuroectodermal tumors (PNET). The optimal treatment for these patients remains a controversy, with authors reporting local radiotherapy to craniospinal irradiation and chemotherapy. We intend to analyze the pattern of care for GBM with neuroectodermal component. MATERIALS AND METHODS: We retrieved data of four patients with GBM-PNET treated in our institute; data were also retrieved from published series to derive treatment and outcome results. RESULTS: In this series, we report the outcome of a series of four patients of GBM-PNET treated with adjuvant radiotherapy and temozolomide. All but one patient underwent gross total resection of the tumor. Adjuvant hypofractionated radiation with concurrent and adjuvant temozolomide was used in all cases. The median follow-up was 12.9 months in the present series. One patient experienced local recurrence 18 months after the treatment. A review of published literature on GBM-PNET was done; studies with details of patient outcome were used for an independent analysis. Twenty-three patients were identified, and the pooled analysis revealed a median progression free and overall survival of 10 and 25, months respectively. Extent of surgery, local radiation vs. craniospinal irradiation, and age at presentation had no impact on the survival. CONCLUSION: GBM PNET is a new entity with only few cases reported so far. Clinical behavior and treatment outcome of these tumors are not different from conventional GBM. However, these patients are at higher risk of CSF dissemination. Hence, an individualized treatment approach is best suited.
