- Abstract
Background: Meningioma is the most prevalent primary intracranial brain tumor and accounts for one-third of all CNS tumors. Meningioma is known to be the most common yet life-threatening brain tumor with a higher recurrence rate. Globally, there is an increase in the healthcare burden due to meningioma and hence in its research. The present clinical approach includes surgical resection, chemotherapy, and radiation therapies to which the malignancy does not seem to respond efficiently. Targeted therapies and molecular markers provide elite patient treatment and care for individuals suffering from meningiomas as compared to conventional measures. Although there is proteomic data on meningioma the knowledge of potential biomarkers differentiating the grades is scarce. To identify the best set of biomarkers, validation of reported markers in large and independent sample cohorts in the future is necessary., Methods: A total of 12 samples, 3 each of control (which made pool 1) meningioma grade I (which made 2 sets: pool 2 and pool 3), and meningioma grade II (which made pool 4) were taken for LC-MS/MS. After this, the expression of three proteins was checked by immunocytochemistry, flow cytometry, and western blotting., Results: Protein expression was analyzed using various techniques like mass spectrometry, immunocytochemistry, flow cytometry, and western blotting. Mass spectrometry is the most commonly used standard and reliable technique for identifying and quantifying protein expression. We got three highly upregulated proteins namely AK2, COL1A1, and PLG using this technique. The biomarker potential of these proteins was further checked by ICC, western blotting, and flow cytometry. Three important proteins were found to be upregulated namely, AK2 (Adenylate kinase 2), COL1A1 (collagen 1A1), and PLG (plasminogen). The order of increased protein expression was control < MG grade I < MG grade II according to mass spectrometry and western blotting. In immunocytochemistry, we found that COL1A1 expression increases significantly with grades in comparison to control. Similarly, AK2 and PLG also showed little increase but not as much as COL1A1. In flow cytometry, PLG showed higher upregulation in grades than control. While AK2 and COL1A1 showed little increase in expression in grades than control. All techniques, especially mass spectrometry and western blotting, presented higher expression of these proteins in grades as compared to control., Conclusions: In the quest to find a suitable therapeutic marker, this study incorporates quantitative labeling and detection followed by flow cytometry, immunocytochemistry, and western blotting for early diagnosis and treatment of meningioma. The article further explores the efficacy of some proteins namely AK2, COL1A1, and PLG to be the targeted molecules., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

- Abstract
Background: Rapidity and reliability are the major advantages of cytopathology in tumor diagnosis. The need for minimal turnaround time for assessing cytological smears has encouraged innovations in staining techniques that require lesser staining time with unequivocal cell morphology. Rapid Pap staining was introduced as a hybrid to conventional Pap stain. It improves staining quality, gets over the staining time in restriction, and is a more efficient technique financially. In the present study, a modified staining technique was adopted where phloxine is added as one of the cytoplasmic stain components in rapid Pap stain kits., Objective: The aim of this study was to assess whether the modification of the existing procedure by adding phloxine as one of the components of the cytoplasmic stain intensifies the cytoplasmic differentiation and cytoplasmic staining in gynecological smears., Materials and Methods: This was a prospective study done on 50 cases of gynecological smears. Two smears were collected from each patient and fixed in 100% propanol and stained with the rapid Pap stain kit procedure and modified rapid Pap stain with phloxine. Slides were then analyzed by two pathologists blinded to the staining method used. Five parameters were considered and scored (background, cell morphology, nuclear staining, cytoplasmic differentiation, and cytoplasmic staining). The quality index for each method was calculated by finding out the ratio of the actual score obtained to the maximum score possible., Results: Both the staining methods had comparable results. For both pathologists, the quality index calculated for modified Pap stain was found to be marginally higher than the quality index for rapid Pap. The mean quality index was comparable for modified Pap (0.91) and rapid Pap (0.89)., Conclusions: The efficacy of modified Pap stain with phloxine to distinctly stain the cytoplasm is comparable with that of rapid Pap stain. In addition, the intensity of staining can be enhanced with little cost outlay, and this can be especially beneficial in low-resource settings., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Cytology.)

- Abstract
Introduction: Most adolescent women face many restrictions, which become much more severe during menstruation. In India, millions of adolescent girls drop out of school every year due to menstruation-related problems and restrictions. Despite extensive research, a paucity of literature was observed on the level of knowledge, attitude, and practices of adolescent girls regarding menstruation. Hence, we proceeded to undertake the present study, to have a deeper understanding of the menstrual hygiene management of adolescents., Aims: To describe the menstrual hygiene management among adolescent school girls., Objectives: (a) To examine the association, if any, between menstrual hygiene management and school absenteeism during menstruation in adolescent school girls., Materials and Methods: We conducted a school-based cross-sectional analytical study in an urban area in north India. The study population comprised adolescent school girls of all the high schools in the urban area. With a 95% confidence interval, and 5% margin of error, the sample size was calculated to be 369. However, an even larger sample size of 600 was actually studied. The probability proportional to size sampling approach was followed based on the number of adolescent girls in each school class/section. Participants were selected through a stratified proportionate sampling method. Ethical approval was obtained from the ethical committee of the district director of education of the urban area where the study was conducted before the commencement of the study. Confidentiality of the information collected was ensured. The data collected was quantitative in nature, using a pretested self-administered questionnaire consisting of both open-ended and close-ended questions. Data was checked for its completeness, coded, and entered into Microsoft Excel 2021 Spreadsheet. Subsequently, the data was imported into IBM Statistical Package for the Social Sciences (SPSS) Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp. for data analysis. Standard statistical methods were utilized for data analysis., Results: The mean age (standard deviation [SD]) of the study participants was 13.68 (1.29). The mean age (SD) at menarche was 13.29 (0.96). Based on the overall menstrual hygiene management score, 377 (62.83%) of the study participants were engaged in good menstrual hygiene management, while 223 (37.17%) were engaged in poor menstrual hygiene management. The mean score (SD) was 7.80 (±0.43). Compared to those aged 17-19 years, those aged 10-13 years had a 0.36 (95% CI 0.17-0.75) decreased odds of good menstrual hygiene, while those aged 14-16 years had a 0.29 (95% CI 0.14-0.59) decreased odds of good menstrual hygiene. The adjusted odds ratios were 0.32 (95% CI 0.19-0.65) and 0.25 (95% CI 0.12-0.41) respectively. Out of 600 study participants, 229 (38.17%) reported school absenteeism at least once in the last 1 year because of menstruation. The mean (standard deviation) duration of school absenteeism was 2.4 (0.78) days per menstrual cycle. The commonest reason for menstruation-related school absenteeism was pain, wherein 105 (45.85%) study participants reported this reason., Conclusion: In our study, we observed that over two-thirds of the study participants were engaged in good menstrual hygiene practices, while ~40% of them reported menstrual-related school absenteeism. Our study also found evidence that the age of the school girls was associated with their menstrual hygiene management practices. We recommend further research on the impact of menstruation and its management on the academic performance of adolescent school girls. Efforts are also required to develop the capacity of teachers to teach menstrual hygiene education., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Family Medicine and Primary Care.)

- Abstract
Gliomas are the most prevalent kind of malignant and severe brain cancer. Apoptosis regulating mechanisms are disturbed in malignant gliomas, as they are in added forms of malignancy. Understanding apoptosis and other associated processes are thought to be critical for understanding the origins of malignant tumors and designing anti-cancerous drugs for the treatment. The purpose of this study was to evaluate the variation in the expression level of several apoptotic proteins that are responsible for apoptosis in low to high-grade glioma. This suggests a significant change in the expression of five apoptotic proteins: Clusterin, HSP27, Catalase, Cytochrome C, and SMAC. Cytochrome C, one of the five substantially altered proteins, is a crucial component of the apoptotic cascade. The complex enzyme Cytochrome C is involved in metabolic pathways such as respiration and cell death. The results demonstrated that Cytochrome C expression levels are lower in glioma tissues than in normal tissues. What's more intriguing is that the expression level decreases with an increase in glioma grades. As a result, the discovery shows that Cytochrome C may be a target for glioma prognostic biomarkers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Rana, Huirem, Kant, Chauhan, Sharma, Yashavarddhan, Chhabra, Acharya, Kalra, Gupta, Jain and Ganguly.)

- Abstract
Objective The evaluation of bone marrow (BM) status is an integral part of the initial workup of patients diagnosed with lymphoma as it plays an important role in staging and predicting prognosis in these patients. This article determines the incidence and pattern of BM involvement in lymphoma cases and distinguishes benign from malignant lymphoid aggregates in BM biopsies. Materials and Methods The study group included 121 cases of Hodgkin and non-Hodgkin lymphomas for which BM biopsies were performed, fixed in acetic acid-zinc formalin solution, decalcified using 10% formic acid, and subjected to hematoxylin and eosin and immunohistochemistry. Results The overall incidence of BM biopsy involvement in our study was 31.4% (37/118), including 34.7% (35/101) in cases of B cell lymphomas, 25% (2/8) in cases of T cell lymphomas, and no involvement in Hodgkin lymphoma. The predominant histological pattern of BM involvement was diffused (14/37; 37.8%), followed by interstitial (10/37; 27.1%). Five cases revealed benign nonparatrabecular lymphoid aggregates which could be confused with lymphomatous involvement, especially in low grade lymphomas. Conclusion A careful examination of the BM biopsies along with clinical history, peripheral blood examination, flow cytometry, and immunohistochemistry will help in arriving at the correct diagnosis., Competing Interests: Conflict of Interest None declared., (The Indian Association of Laboratory Physicians.

- Abstract
Gliomas are the most common type of the malignant brain tumor, which arise from glial cells. They make up about 40% of all primary brain tumors and around 70% of all primary malignant brain tumors. They can occur anywhere in the central nervous system (CNS) and have a poor prognosis. The average survival of glioma patients is approximately 6-15 months with poor aspects of life. In this edge, identification of proteins secreted by cancer cells is of special interest because it may provide a better understanding of tumor progression and provide early diagnosis of the diseases. Extracellular vesicles (EVs) were isolated from pooled plasma of healthy controls (n=03) and patients with different grades of glioma (Grade I or II or III, n=03 each). Nanoparticle tracking analysis, western blot, and flow cytometry were performed to determine the size, morphology, the concentration of glioma-derived vesicles and EV marker, CD63. Further, iTRAQ-based LC-MS/MS analysis of EV protein was performed to determine the differential protein abundance in extracellular vesicles across different glioma grades. We further verified galectin-3 binding protein (LGALS3BP) by ELISA in individual blood plasma and plasma-derived vesicles from control and glioma patients (n=40 each). Analysis by Max Quant identified 123 proteins from the pooled patient exosomes, out of which 34, 21, and 14 proteins were found to be differentially abundant by more than 1.3-fold in the different grades of glioma grade I, pilocytic astrocytoma; grade II, diffuse astrocytoma; grade III, anaplastic astrocytoma, respectively, in comparison with the control samples. A total of seven proteins-namely, CRP, SAA2, SERPINA3, SAA1, C4A, LV211, and KV112-showed differential abundance in all the three grades. LGALS3BP was seen to be upregulated across the different grades, and ELISA analysis from individual blood plasma and plasma-derived extracellular vesicles confirmed the increased expression of LGALS3BP in glioma patients (p<0.001). The present study provides LGALS3BP as a potential biomarker for early detection of glioma and improve survival outcome of the patient. The present study further provides the information of progression and monitoring the tumor grades (grade 1, grade II, grade III)., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Rana, Chauhan, Gautam, Kulkarni, Banarjee, Chugh, Chhabra, Acharya, Kalra, Gupta, Jain and Ganguly.)

- Abstract
Meningioma is the second most common type of intracranial brain tumor. Immunohistochemical techniques have shown prodigious results in the role of epidermal growth factor receptor variant III (EGFR vIII) in glioma and other cancers. However, the role of EGFR vIII in meningioma is still in question. This study attempt the confer searches for the position attained by EGFR vIII in progression and expression of meningioma. Immunohistochemistry technique showed that EGFR vIII is highly expressed in benign tumors as compared to the atypical meningioma with a highly significant p-value (p<0.05). Further analysis by flow cytometry results supported these findings thus presented high intensity of EGFR vIII in low grades of meningioma. The study revealed that the significant Ki 67 values, to predictor marker for survival and prognosis of the patients. Higher expression of EGFR vIII in low grades meningiomas as compared to high-grade tumors indicate towards its oncogenic properties. To our knowledge, limited studies reported in literature expressing the EGFR vIII in meningioma tumors. Hence, Opinions regarding the role that EGFR vIII in tumorigenesis and tumor progression are clearly conflicting and, therefore, it is crucial not only to find out its mechanism of action, but also to definitely identify its role in meningioma., Competing Interests: The authors declare they have no conflicts of interest.

- Abstract
Background: The coronavirus disease 2019 (COVID 19) is a zoonotic viral infection that originated in Wuhan, China, in December 2019. It was declared a pandemic by the World Health Organization shortly thereafter. This pandemic is going to have a lasting impact on the functioning of pathology laboratories due to the frequent handling of potentially infectious samples by the laboratory personnel. To deal with this unprecedented situation, various national and international guidelines have been put forward outlining the precautions to be taken during sample processing from a potentially infectious patient., Purpose: Most of these guidelines are centered around laboratories that are a part of designated COVID 19 hospitals. However, proper protocols need to be in place in all laboratories, irrespective of whether they are a part of COVID 19 hospital or not as this would greatly reduce the risk of exposure of laboratory/hospital personnel. As part of a laboratory associated with a rural cancer hospital which is not a dedicated COVID 19 hospital, we aim to present our institute's experience in handling pathology specimens during the COVID 19 era., Conclusion: We hope this will address the concerns of small to medium sized laboratories and help them build an effective strategy required for protecting the laboratory personnel from risk of exposure and also ensure smooth and optimum functioning of the laboratory services., Competing Interests: None

- Abstract
Background: Small for gestational age (SGA) is common among newborns in low-income countries like Nepal and has higher immediate mortality and morbidities., Objectives: To study the prevalence and prognostic factors of SGA babies in Western Nepal., Methods: A cross-sectional study (November 2016-October 2017) was conducted in a tertiary care hospital in Western Nepal. Socio-demographic, lifestyle factors including diet, and exposures including smoking and household air pollution in mothers who delivered newborns appropriate for gestational age (AGA), SGA and large for gestational age (LGA) were recorded. Logistic regression was carried out to find the odds ratio of prognostic factors after adjusting for potential confounders., Results: Out of 4000 delivered babies, 77% (n = 3078) were AGA, 20.3% (n = 813) were SGA and 2.7% (n = 109) were LGA. The proportion of female-SGA was greater in comparison to male-SGA (n = 427, 52.5% vs n = 386, 47.5%). SGA babies were born to mothers who had term, preterm, and postterm delivery in the following proportions 70.1%, 19.3%, and 10.6%, respectively. The average weight gain (mean ± SD) by mothers in AGA pregnancies was 10.3 ± 2.4 kg, whereas in SGA were 9.3 ± 2.4 kg. In addition to low socioeconomic status (OR 1.9, 95% CI 1.1, 3.2), other prognostic factors associated with SGA were lifestyle factors such as low maternal sleep duration (OR 5.1, CI 3.6, 7.4) and monthly or less frequent meat intake (OR 5.0, CI 3.2, 7.8). Besides smoking (OR 8.8, CI 2.1, 36.3), the other major environmental factor associated with SGA was exposure to household air pollution (OR 5.4, 4.1, 6.9) during pregnancy. Similarly, some of the adverse health conditions associated with a significantly higher risk of SGA were anemia, oligohydramnios, and gestational diabetes., Conclusions: SGA is common in Western Nepal and associated with several modifiable prognostic factors., Competing Interests: The authors declare that there is no conflict of interests., (© 2021 The Authors.

- Abstract
Background: Cystoisospora is a well-known opportunistic enteric parasite among human immunodeficiency virus (HIV) seropositive patients but there is a paucity of data among HIV negative patients. This study investigated Cystosporiasis on both HIV positive and negative patients, with or without diarrhea, presenting to a tertiary care and super specialty center of northern India., Methodology: Oocysts of Cystoisospora were detected on light microscopy, by modified Kinyoun staining of stool specimens, over an 11-year study period., Results: Of the 10,233 stool specimens evaluated, Cystoisospora was detected in 64 patients, 37 (57.81%) of whom were HIV positive. Year-wise analysis showed an overall declining trend of cystoisosporiasis. Maximum cases were detected in May and June in HIV positive patients and February and September among HIV negative patients. Among HIV positive patients, the mean CD4 count was 152.04 ± 81.12cells/μL, mean absolute eosinophil count (AEC) was 229.16 ± 175.62 cells/μL and 12.5% patients had mild eosinophilia. Tuberculosis was the most common co-morbidity. Dual infections of Cystoisospora with Cryptosporidium and Giardia were also seen. Among HIV negative patients, eight had primary autoimmune disorders, seven were solid organ transplant recipients and the rest had chronic bowel diseases. The mean AEC was 485.47 ± 414.88 cells/μL, with 14.81% patients showing mild and 11.11% showing marked eosinophilia. Dual infection with Giardia was seen. Recurrent cystoisosporiasis was noted, despite cotrimoxazole treatment in a single case., Conclusion: The epidemiology of cystoisosporiasis differs between HIV seropositive and seronegative patients in terms of year-wise and month-wise trends, co-infections and most importantly, AECs., Competing Interests: None

- Abstract
Aim: Primary pineal melanoma is a rare tumor. We herein review the histogenesis, pathology, radiology and therapeutic options of this rare tumor., Material and Methods: We conducted a PUBMED search using a combination of keywords such as "primary pineal melanoma", "CNS melanoma", and "pineal tumor" and identified 16 cases of primary pineal melanoma. Clinical features, pathologic characteristics and treatment details of these patients were noted from respective case reports. We also describe a case of a 45-year-old Indian woman with primary pineal melanoma treated with a combination of surgery and post-op radiation., Results: The median age at presentation is 50 years. Median duration of symptoms is 6 weeks. Common symptoms at presentation include headache (58.8%), personality changes (41.2%), gait disturbance (35.3%) and Parinaud's syndrome (29.4%). Surgery, radiotherapy and chemotherapy have been used in 29.4%, 47.1% and 23.5% of patients respectively. Median overall survival is 56 weeks. Leptomeningeal dissemination and ventricular ependymal spread were noted in 70.6% and 35.3% patients, respectively., Conclusion: Combined modality treatment comprising maximal safe surgery and post-operative radiation should be preferred in patients with localized pineal melanoma without leptomeningeal dissemination. Taking a cue from other subsites of melanoma, chemotherapy can perhaps be deferred until recurrence.

- Abstract
Purpose: This study uses linked cycles of assisted reproductive technology (ART) to examine cumulative live birth rates, birthweight, and length of gestation by diagnostic category., Methods: We studied 145,660 women with 235,985 ART cycles reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System during 2004-2010. ART cycles were linked to individual women by name, date of birth, social security number, partner's name, and sequence of ART treatments. The study population included the first four autologous oocyte cycles for women with a single diagnosis of male factor, endometriosis, ovulation disorders, diminished ovarian reserve, or unexplained infertility. Live birth rates were calculated per cycle, per cycle number (1-4), and cumulatively. Birthweight and length of gestation were calculated for singleton births., Results: Within each diagnosis, live birth rates were highest in the first cycle and declined with successive cycles. Women with diminished ovarian reserve had the lowest live birth rate (cumulative rate of 28.3 %); the live birth rate for the other diagnoses were very similar (cumulative rates from 62.1 % to 65.7 %). Singleton birthweights and lengths of gestation did not differ substantially across diagnoses, ranging from 3,112 to 3,286 g and 265 to 270 days, respectively. These outcomes were comparable with national averages for singleton births in the United States (3,296 g and 271 days)., Conclusion: Women with the diagnosis of diminished ovarian reserve had substantially lower live birth rates. However, singleton birthweights and lengths of gestation outcomes were similar across all other diagnoses.

- Abstract
Objective: To assess whether women with polycystic ovary syndrome (PCOS) follow the same age-related decline in IVF outcomes as women with tubal factor infertility over the reproductive life span. PCOS is characterized by increased ovarian reserve as assessed by antral follicle counts and anti-Müllerian hormone levels. It is unclear whether these surrogate markers of ovarian reserve reflect a true lengthening of the reproductive window., Design: Retrospective cohort., Setting: Not applicable., Patient(s): Women with PCOS and tubal factor infertility (42,286 cycles)., Intervention(s): IVF., Main Outcome Measure(s): Pregnancy and live-birth rates., Result(s): The mean number of oocytes retrieved was higher in women with PCOS compared with in women with tubal factor (16.4 vs. 12.8; odds ratio [OR], 1.27; 95% confidence interval [CI], 1.25-1.29). The clinical pregnancy (42.5% vs. 35.8%; OR, 1.32; 95% CI, 1.27-1.38) and live-birth rates were also increased in women with PCOS (34.8% vs. 29.1%; OR, 1.30; 95% CI, 1.24-1.35). A similar rate of decline in clinical pregnancy and live-birth rates was noted in both groups (20-44 years). The implantation, clinical pregnancy, miscarriage, and live-birth rates were not significantly different for each year after age 40 in the two groups., Conclusion(s): Despite a higher oocyte yield in all age groups, women with PCOS over age 40 had similar clinical pregnancy and live-birth rates compared with women with tubal factor infertility. These findings suggest that the reproductive window may not be extended in PCOS and that patients with infertility should be treated in a timely manner despite indicators of high ovarian reserve., (Copyright © 2013 American Society for Reproductive Medicine.

- Abstract
The majority of perinatal morbidity after in vitro fertilization (IVF) is due to multiple pregnancy; however, even singleton infants are at an increased risk for adverse outcomes. We have summarized data that evaluates adverse outcomes in IVF infants and recent attempts to delineate the underlying causes of this risk. We submit that practitioners of reproductive medicine should remain at the forefront of this investigation., (Copyright © 2011 American Society for Reproductive Medicine. Published by Elsevier Inc.

- Abstract
Childhood-onset obsessive-compulsive disorder (OCD) affects 1%-2% of children and adolescents. It is characterized by recurrent obsessions and compulsions that create distress and interfere with daily life. The symptoms reported by children are similar to those seen among individuals who develop OCD in adulthood, and the two groups of patients are treated with similar symptom-relieving behavior therapies and medications. However, there are differences in sex ratios, patterns of comorbidity, and the results of neuroimaging studies that might be important. Here we review the diagnosis and treatment of childhood-onset OCD in light of pediatric and adult studies. We also discuss current knowledge of the pathophysiology of the disorder. Despite advances in this area, further research is needed to understand better the etiopathogenesis of the disorder and to develop new, more effective therapeutic options.

- Abstract
Background: The occipitocervical contoured rod (CR) stabilization for use in craniovertebral junction (CVJ) pathologies is an effective and economical technique of posterior fusion (PF)., Aims: The various indications for CR in CVJ pathologies are discussed., Settings and Design: Retrospective analysis., Materials and Methods: Fifty-four patients (mean age: 31.02+/-13.44 years; male: female ratio=5.75:1) who underwent CR stabilization are included. The majority had congenital atlantoaxial dislocation (AAD; n=50); two had CVJ tuberculosis; one each had rheumatoid arthritis and C2-3 listhesis, respectively. The indications for CR fusion in congenital AAD were associated Chiari 1 malformation (C1M) (n=29); occipitalized C1 arch and/or malformed or deficient C1 or C2 posterior elements (n=9); hypermobile AAD (n=2); and, rotatory AAD (n=3). Contoured rod as a revision procedure was also performed in seven patients. Most patients were in poor grade (18 in Grade III [partial dependence for daily needs] and 15 in Grade IV [total dependence]); 15 patients were in Grade II [independent except for minor deficits] and six in Grade I [no weakness except hyperreflexia or neck pain]., Results: Twenty-four patients improved, 18 stabilized and six deteriorated at a mean follow-up (FU) of 17.78+/-19.75 (2-84) months. Six patients were lost to FU. In 37 patients with a FU of at least three months, stability and bony union could be assessed. Thirty-one of them achieved a bony fusion/stable construct., Conclusions: Contoured rod is especially useful for PF in cases of congenital AAD with coexisting CIM, cervical scoliosis, sub-axial instability and/or asymmetrical facet joints. In acquired pathologies with three-column instability, inclusion of joints one level above the affected one by using CR, especially enhances stability.

- Abstract
Background: Chiari I malformation with atlantoaxial dislocation may cause both posterior and anterior cervicomedullary compression. We studied the clinicoradiological features and surgical outcome in patients having Chiari I malformation with atlantoaxial dislocation., Method: Thirty-nine patients with Chiari I malformation with atlanto-axial dislocation underwent preoperative and follow-up neurological status assessment. In Chiari I malformation with reducible atlanto-axial dislocation (n = 11), a direct posterior stabilization was done. In Chiari I malformation with irreducible atlanto-axial dislocation (n = 28), a single stage transoral decompression with posterior stabilization and/or posterior decompression and duraplasty were done in 18 patients. In 10 patients, only posterior decompression and/or posterior stabilization was performed. Seven among the latter patients subsequently deteriorated and required transoral decompression. Comparison of mean neurological status scores of patients with Chiari I malformation with irreducible atlanto-axial dislocation who underwent single stage transoral decompression with posterior stabilization versus the posterior procedure alone was done using T-test and proportional significance also calculated., Findings: Patients with Chiari I malformation with atlanto-axial dislocation have a high incidence of long tract signs and sphincteric disturbances with a decrease in the mean foramen magnum diameter. The mean neurological status scores of patients with Chiari I malformation with irreducible atlanto-axial dislocation who underwent single stage transoral decompression with posterior stabilization were significantly better than those patients who underwent the posterior procedure alone. The latter patients also showed significant clinical improvement following transoral decompression. In the presence of Chiari I malformation with reducible atlanto-axial dislocation, reduction and stabilization of atlanto-axial dislocation resulted in neurological improvement. The follow up neurological status scores of these patients improved after surgical intervention even in the presence of poor preoperative grades., Conclusions: Patients with Chiari I malformation should be investigated for the presence of atlanto-axial dislocation. In case atlantoaxial dislocation coexists, priority must be given to relieving anterior cervicomedullary compression.
