This study from southern India showed that proximal hip geometry was significantly impaired in postmenopausal women with femoral neck fracture. The trabecular bone score (TBS), which is reflective of bone microarchitecture, was also significantly impaired in patients with fracture. Introduction: There is limited information with regard to comprehensive bone health in Indian postmenopausal women with neck of femur fracture. We studied the bone mineral density (BMD), trabecular bone score (TBS), proximal hip geometry, and bone mineral biochemistry in postmenopausal women with and without femoral neck fractures. Methods: This was a cross-sectional study conducted at a tertiary care center in South India. BMD, TBS, and hip structural analysis (HSA) were assessed using a dual-energy X-ray absorptiometry (DXA) scanner. Bone mineral biochemical profiles were also studied. Results: A total of 90 postmenopausal women with acute femoral neck fracture with mean (SD) age of 63.2 (6.1) years and 90 age-matched controls were included. The prevalence of osteoporosis was higher among cases as compared to controls (83.3% vs 47.8%; P < 0.001). Degraded bone microarchitecture (TBS value < 1.200) was more frequent among women with hip fracture as compared to controls (46.7% vs 31.1%; P = 0.032). Cross-sectional moment of inertia (CSMI) was significantly lower at the narrow neck (NN) and inter-trochanteric (IT) region in cases (P < 0.05) and buckling ratio (BR) was significantly higher at all three sites in postmenopausal women with femoral neck fracture as compared controls. Multivariate logistic regression analysis showed that femoral neck osteoporosis, low CSMI at NN and high BR at NN and femoral shaft emerged as factors significantly associated with femoral neck fractures. Conclusion: This study highlights that impaired parameters of proximal hip geometry and a low trabecular bone score may be significantly associated with femoral neck fractures in postmenopausal women.
Context Prophylactic antibiotics are usually not recommended for an in and out catheterization. However procedures involving similar catheterizations like micturition cystourethrogram (MCUG) and cystometrogram are being performed under prophylactic antibiotic cover. Aims We aim to find the incidence of symptomatic urinary tract infections following MCUG done in children without antibiotic cover. Settings and design A retrospective cross sectional study was conducted on 398 patients who underwent MCUG from January 2015 to January 2016. The median age was 24 months and here were 272 males and 126 females, with 102 of them being infants. Methods and material Urine microscopy or culture was checked before performing the MCUG and only those without UTI were included in the study. Those with symptomatic and culture proven UTI within 2 weeks post-MCUG were defined as having post-procedure UTI (ppUTI). The incidence of post-procedure UTI was calculated and was compared with other studies. Statistical analysis used Data was entered in Microsoft Excel and analyzed using SPSS. Categorical variables were summarized as percentage and continuous variables were summarized as mean with standard deviation. Results Symptomatic procedure induced UTI were seen in only 3 of the 398 (0.75%) patients with a 95% CI of 0.02–0.008. Conclusions Strict adherence to aseptic precautions while performing an MCUG and prompt initiation of appropriate therapy when indicated may help obviate the need for routine administration of pre procedure antibiotics before MCUG.
Background Pneumopericardium is a rare complication in patients with bacterial necrotizing pneumonia and proven to be lethal with a high incidence of mortality due to cardiopulmonary failure. Case presentation This is a rare case of broncho-pericardial fistula in a 21 year old, who was a known case of T-cell acute lymphoblastic leukemia status post-chemotherapy, presented with relapse of acute lymphoblastic leukemia. He was evaluated for febrile neutropenia. Further investigation showed features of necrotizing pneumonia and follow-up chest X-ray during the hospital stay showed evidence of pneumopericardium. To localize the cause, computed tomography chest was performed, further confirming the etiology of bronchopericardial fistula. Conclusions Our case illustrates broncho-pericardial fistula as a rare complication of necrotizing pneumonia and the utility of multimodality imaging in its diagnosis and determination of tension pneumopericardium.
Background Health-care-associated infections (HAIs) cause significant morbidity and mortality globally, including in low-income and middle-income countries (LMICs). Networks of hospitals implementing standardised HAI surveillance can provide valuable data on HAI burden, and identify and monitor HAI prevention gaps. Hospitals in many LMICs use HAI case definitions developed for higher-resourced settings, which require human resources and laboratory and imaging tests that are often not available. Methods A network of 26 tertiary-level hospitals in India was created to implement HAI surveillance and prevention activities. Existing HAI case definitions were modified to facilitate standardised, resource-appropriate surveillance across hospitals. Hospitals identified health-care-associated bloodstream infections and urinary tract infections (UTIs) and reported clinical and microbiological data to the network for analysis. Findings 26 network hospitals reported 2622 health-care-associated bloodstream infections and 737 health-care-associated UTIs from 89 intensive care units (ICUs) between May 1, 2017, and Oct 31, 2018. Central line-associated bloodstream infection rates were highest in neonatal ICUs (>20 per 1000 central line days). Catheter-associated UTI rates were highest in paediatric medical ICUs (4·5 per 1000 urinary catheter days). Klebsiella spp (24·8%) were the most frequent organism in bloodstream infections and Candida spp (29·4%) in UTIs. Carbapenem resistance was common in Gram-negative infections, occurring in 72% of bloodstream infections and 76% of UTIs caused by Klebsiella spp, 77% of bloodstream infections and 76% of UTIs caused by Acinetobacter spp, and 64% of bloodstream infections and 72% of UTIs caused by Pseudomonas spp. Interpretation The first standardised HAI surveillance network in India has succeeded in implementing locally adapted and context-appropriate protocols consistently across hospitals and has been able to identify a large number of HAIs. Network data show high HAI and antimicrobial resistance rates in tertiary hospitals, showing the importance of implementing multimodal HAI prevention and antimicrobial resistance containment strategies.

To understand the referral pathways followed by families, the highest level of health facility reached for care, the time taken to receive that level of maternal healthcare, and families’ experiences of care received, we conducted a qualitative study of six maternal deaths, 10 perceived postpartum hemorrhage, and 14 frontline health workers. Thematic analysis of the data showed that of the six maternal death cases, one went directly to a secondary care public hospital, four women visited four to five hospitals before they died. One of them died after visiting four hospitals in over 30 h. Of the 10 women who experienced postpartum hemorrhage, six never went to a hospital, three went to two hospitals, and one was in the hospital when the event occurred. Time taken from the first step of care-seeking outside the home to initiation of care at the highest level ranged from 11 h to 8 days. The providers of the public health system followed a hierarchical 'referral pyramid' irrespective of whether the next level hospital could provide appropriate care or not. This research provides evidence to the ‘outer setting’ domain of the Consolidated Framework for Implementation Science from families’ perspectives about their needs and the referral network. Providing information about emergency obstetric care services to all the hospitals within a district and developing a communication system through the Federation of Obstetric and Gynaecological Societies of India for care continuum through referral would help reduce mortality and improve family’s experience with the health system.
Purpose The present study examines the association between psychological violence and posttraumatic stress disorder (PTSD), depression, and anxiety, while comparing the specific subtypes of psychological violence and simultaneously focusing on methodological shortcomings. Method A systematic review and random-effects meta-analyses were applied on the three main outcomes: PTSD, depression, and anxiety. Four electronic databases were searched (PsycINFO, PubMed, EMBASE, and Web of Science), and a total of 194 studies were included ( k = 149 for meta-analyses). GRADEpro was used to evaluate the certainty of the evidence from the meta-analyses. Results Psychological violence had strong associations with the three main outcomes, with the strongest association for PTSD in both female and male victims. Coercive control was particularly associated with PTSD for female victims, while emotional/verbal and dominance/isolation had the strongest association with depression. Although the identified studies were characterized by gender bias, psychological violence appear to affect male mental health too. Discussion Findings from the meta-analyses support the notion that psychological violence is a traumatic experience, which is strongly association with PTSD and other common mental health problems linked to trauma. GRADEpro rated the certainty of evince to be low, and thus, our confidence in the estimated effect is limited. Gender bias, the applied terminology, and other methodological shortcomings are discussed. Despite the substantial amount of research on this topic, more research is needed before we can draw any final conclusions on the effect of psychological violence on mental health.
Objectives Popular animal models of septic shock involve injections of endotoxin (bacterial lipopolysaccharide). Other methods that induce sepsis are often time-consuming and require long-term monitoring facilities. Further, individual models using different bacterial strains can deepen our understanding of sepsis pathophysiology. Hence, our objective was to develop an acute and functional Wistar rat model of septic shock using live strains of Escherichia coli and then administer Noradrenaline, a known sympathomimetic drug, to study if the response is along expected lines. Materials and Methods After random allocation to one of three groups (Group 1 – E. coli alone, n=7; Group 2 – E. coli followed by Noradrenaline, n = 7 and Group 3 – control ( n = 4), which received saline injections), Wistar rats were anesthetised and intra-arterial pressure was recorded from carotid artery catheter. Live E. coli suspended in normal saline (5 Mcfarland concentration; dose – 650 uL/100 g body weight) was injected through the tail vein to induce sepsis. When mean arterial pressure dropped to 50% of its value before E. coli injection, Noradrenaline was injected in Group 2. Results The average time (t1, n = 14) for the septic shock to set in was about 1.94 ± 0.97 h. Six out of seven rats (Group 1) died within 60 min without intervention. The addition of Noradrenaline after hypotension in Group 2 prolonged the time to death significantly by about 170 min. Conclusion The rat septic shock model using E. coli described in the study is an acute, stable, and functional model to study various aspects of septic shock. Administration of Noradrenaline prolonged the animal’s life in septic shock as expected. Future studies using other common sepsis agents encountered in clinics can be undertaken similarly.
Objective Incomplete surgical removal of craniopharyngiomas frequently results in suboptimal oncological control. Radiation therapy is usually offered in these cases to prevent local recurrence of disease; however, the efficacy of radiation is limited by its potential adverse effect, particularly in younger patients. This study was undertaken to compare long-term outcomes and rates of postoperative obesity and endocrinopathy in patients undergoing either upfront adjuvant radiation after surgery, or postoperative surveillance with progression-contingent intervention. Methods Thirty-seven patients aged <25 years who had undergone primary incomplete surgical resection of craniopharyngiomas were retrospectively identified and categorized according to the prescribed treatment strategy. Recurrence rates, functional status, neuro-ophthalmologic, and endocrine outcomes were studied in both groups of patients. Results Twenty-three patients received upfront adjuvant radiation, and 14 patients underwent postoperative surveillance. Adjuvant radiation in the former group was delivered using either conventional (n=10), 3D-conformal (n=4), or fractionated stereotactic (n=9) techniques using a linear accelerator. The mean follow-up duration was 64.7 months (range 14–134 months). Disease progression was significantly higher in patients undergoing surveillance as compared to those undergoing upfront adjuvant radiation (71.4 versus 17.4%; p=0.002). Median progression-free survival times were 129 months and 27 months in the upfront adjuvant radiation and surveillance groups, respectively (p=0.007). In patients undergoing surveillance, 50% ultimately required irradiation, and the median radiation-free survival time in this subgroup was 57 months. Two children in the adjuvant radiation group developed asymptomatic radiation-related vasculopathies on follow-up; however, there were no statistically significant differences between the two groups in terms of visual, functional, or pituitary-hypothalamic function at last follow-up. Conclusions In comparison to upfront adjuvant radiation following incomplete craniopharyngioma resection significantly, a strategy of postoperative surveillance resulted in less durable disease control but allowed radiation therapy to be delayed by a median time of 57 months, without significant detriment to global functional, visual, and neuro-endocrinological outcomes. The merits and demerits of either strategy should be carefully considered in the post-surgical management of these patients.
Introduction. Adamantinoma is sub-classified into classic/biphasic, osteofibrous dysplasia-like, and de-differentiated type. We present six adamantinomas with a prominent spindle cell component mimicking intraosseous synovial sarcomas. Methods. Six patients were either referred with a diagnosis of intraosseous synovial sarcoma or wherein synovial sarcoma was a differential diagnosis. Three tumors were tested for SS18 gene rearrangement by FISH and two for SS18::SSX fusion by RT-PCR technique. Results. There were three males and three females with an average age of 20.6 years. Radiologically, the lesions were expansile and showed lytic and/or sclerotic components, involving the cortex and/or medulla. Five lesions occurred in the tibia and two in the fibula. Two tumors displayed soft tissue extension and two occurred as multifocal lesions. Two patients were diagnosed with synovial sarcoma and a single patient with sarcomatoid carcinoma, elsewhere. Two “in-house” patients were initially diagnosed with synovial sarcomas. On review, all tumors were cellular comprising monomorphic spindle-shaped cells arranged in sheets and fascicles (n = 6), including a “herringbone-like” pattern (n = 3), focal tubules (n = 1), cohesive nests (n = 5), cords (n = 2), including pseudocystic component (n = 2). Immunohistochemically, tumor cells were positive for p63 (6/6), p40 (4/4), EMA (2/3), AE1/AE3 (5/6), various keratins (2/2), and TLE1 (2/4). Three tumors tested for SS18 rearrangement were negative, while two tumors tested for SS18::SSX fusion were negative. Conclusions. Adamantinomas with spindle cell morphology display overlapping features with synovial sarcoma. A clinico-radiological index of suspicion immunostains (p63 and p40) and molecular test for t(X; 18) translocation are useful in an exact diagnosis, which has treatment-related implications.
Background/aims: Inflammatory bowel disease (IBD) is increasingly being recognized in elderly patients. Data on clinical spectrum of elderly-onset IBD patients is lacking from India. Methods: A cross-sectional retrospective analysis of a prospectively maintained database of patients diagnosed with IBD was conducted at 2 centers in India. The clinical spectrum of elderly-onset IBD including demographic profile (age and sex), clinical presentation, disease characteristics (disease behavior and severity, extent of disease), and treatment were recorded and compared with adult-onset IBD. Results: During the study period, 3,922 (3,172 ulcerative colitis [UC] and 750 Crohn's disease [CD]) patients with IBD were recorded in the database. A total of 186 patients (4.74%; 116 males [62.36%]) had elderly-onset IBD (69.35% UC and 30.64% CD). Diarrhea, blood in stools, nocturnal frequency and pain abdomen were the commonest presentations for UC, whereas pain abdomen, weight loss and diarrhea were the most frequent symptoms in CD. For both elderly onset UC and CD, majority of the patients had moderately severe disease. Left-sided colitis was the commonest disease location in UC. Isolated ileal disease and inflammatory behavior were the most common disease location and behavior, respectively in CD. 5-Aminosalicylates were the commonest prescribed drug for both elderly onset UC and CD. Thiopurines and biologics were used infrequently. Prevalence of colorectal cancer was higher in elderly onset IBD. Conclusions: Elderly onset IBD is not uncommon in India. Both the elderly onset UC and CD were milder, with no significant differences in disease characteristics (disease extent, location and behavior) when compared to adult-onset IBD. Colorectal cancer was more common in elderly onset IBD.
Purpose To evaluate association between clinical and pathological findings and repeated recurrence in sinonasal inverted papilloma. Methods Retrospective cohort study conducted at a tertiary care teaching hospital included all patients operated for inverted papilloma from January 2010 to December 2019. Patients were categorized as primary and recurrent cases. Based on disease status at follow-up, they were subcategorized into ‘primary with no recurrence’ (PnR), ‘primary with recurrence’ (PwR), ‘recurrent with no further recurrence’ (RnR), and ‘recurrent with further recurrence’ (RwR) groups. Data including demography, clinical, endoscopic and pathological findings were collected and analyzed. Results Increased incidence of pale appearance of lesion in RnR group (p = 0.017), polypoidal appearance in primary group (p = 0.002) and fibrous appearance in the recurrent group (p = 0.002) were statistically significant. Predominant epithelium was combined respiratory and squamous epithelium in primary and recurrent groups and also in RnR group (p = 0.019), while it was squamous (p = 0.024) in RwR group. Epithelial hyperplasia was more common in primary and RnR groups. Oncocytic change, cystic dilatation, microabscess and squamous metaplasia were seen more in recurrent and RnR groups. Cytoplasmic glycogenation was more in recurrent and RwR groups. Stroma was predominantly edematous in all the groups. Conclusions Patients with recurrence are younger and present earlier than those with primary disease. Fleshy appearance and pink/red colour of tumour, lining epithelium being squamous and cytoplasmic glycogenation could be considered as features predicting recurrence. Negative predictors of recurrence of IP include pale appearance of tumour, combined respiratory and squamous epithelium lining and squamous metaplasia.
Objective: To summarize latent tuberculosis infection (LTBI) management strategies among household contacts of bacteriologically confirmed pulmonary tuberculosis (TB) patients in high-TB burden countries. Methods: PubMed/MEDLINE (NCBI) and Scopus were searched (January 2006 to December 2021) for studies reporting primary data on LTBI management. Study selection, data management and data synthesis were protocol-driven (PROSPERO-CRD42021208715). Primary outcomes were the proportions with LTBI and initiating and completing tuberculosis preventive treatment (TPT). Reported factors influencing the LTBI care cascade were qualitatively synthesised. Results: From 3692 unique records retrieved, 58 studies from 23 countries were included. Most identified contacts were screened (median 99%, IQR 82% to 100%; 46 studies). Random-effects meta-analysis yielded pooled proportions for: LTBI 41% (95% CI % 33% to 49%; 21,566 tested contacts); TPT initiation 91% (95% CI 79% to 97%; 129,573 eligible contacts, 34 studies); TPT completion 65% (95% CI 54% to 74%; 108,679 TPT-initiated contacts, 28 studies). Heterogeneity was significant (I2 ≥95% to 100%) and could not be explained in subgroup analyses. Median proportions (IQR) were: LTBI 44% (28% to 59%); TPT initiation 86% (60% to 100%); TPT completion 68% (44% to 82%). Nine broad themes related to diagnostic testing, health system structure and functions, risk perception, documentation and adherence were considered likely to influence the LTBI care cascade. Conclusion: The proportions of household contacts screened, detected with LTBI and initiated on TPT, though variable were high, but the proportions completing TPT were lower indicating current strategies used for LTBI management in high TB burden countries are not sufficient.

Introduction Chondroprogenitors (CPCs) have emerged as a promising cellular therapy for cartilage-related pathologies due to their inherent primed chondrogenic potential. Studies report that the addition of growth factors such as parathyroid hormone (PTH) and Bone Morphogenic Protein (BMP) enhance the chondroinducive potential in chondrocytes and mesenchymal stem cells. This study evaluated if supplementation of the standard culture medium for cell expansion with 1–34 PTH and BMP-9 would enhance the chondrogenic potential of CPCs and reduce their hypertrophic tendency. Methods Human chondrocytes were isolated from patients undergoing total knee replacement for osteoarthritis (n = 3). Following fibronectin adhesion assay, passage 1 CPCs were divided and further expanded under three culture conditions (a) control, i.e., cells continued under standard culture conditions, (b) 1–34 PTH group, additional intermittent 6 h exposure with 1–34 PTH and (c) BMP-9 group, additional BMP-9 during culture expansion. All the groups were evaluated for population-doubling, cell cycle analysis, surface marker and gene expression for chondrogenesis, hypertrophy, multilineage differentiation and GAG (glycosaminoglycan)/DNA following chondrogenic differentiation. Results Concerning growth kinetics, the BMP-9 group exhibited a significantly lower S-phase and population-doubling when compared to the other two groups. Qualitative analysis for chondrogenic potential (Alcian blue, Safranin O staining and Toluidine blue for GAG) revealed that the BMP-9 group exhibited the highest uptake. The BMP-9 group also showed significantly higher COL2A1 expression than the control group, with no change in the hypertrophy marker expression. Conclusion BMP-9 can potentially be used as an additive for CPCs expansion, to enhance their chondrogenic potential without affecting their low hypertrophic tendency. The mitigating effects of 1-34PTH on hypertrophy would benefit further investigation when used in combination with BMP-9 to enhance chondrogenesis whilst reducing hypertrophy.
Anti-U1RNP antibody is associated with distinct organ involvement in patients with systemic lupus erythematosus (SLE). Nailfold capillaroscopy (NFC) allows non-invasive assessment of microvascular abnormalities in several connective tissue diseases. The objective of this study is to determine the association of anti-U1RNP antibody with microvascular changes by NFC in RNP-positive SLE patients in comparison with RNP-negative SLE patients (negative disease controls) and mixed connective tissue disease (MCTD) cases (positive disease controls). NFC examination was performed in consecutive patients with SLE with or without anti-U1RNP positivity. MCTD patients were recruited as disease controls. Abnormalities noted in the three groups were compared using non-parametric tests. Ordinal logistic or linear regression was used wherever applicable. 81 patients were studied, of whom 28 were diagnosed as RNP-positive SLE (age 30.0 ± 10.37; 26 females), 26 were RNP-negative SLE (age 29.42 ± 9.20; 25 females) and 27 had MCTD (age36.5 ± 9.70; 25 females). RNP-positive SLE patients had more frequent giant capillaries, enlarged capillaries and ramified capillaries as compared to RNP-negative SLE (p = 0.05, < 0.01 and 0.03, respectively). The capillary density was lower in patients with MCTD as compared with patients with RNP-positive SLE (5.11 ± 1.69/mm vs 7.25 ± 1.38/ mm, p < 0.01) and RNP-negative SLE (8.92 ± 1.13/mm, p < 0.01). The reduction in capillary density was less severe in patients with RNP-negative SLE as compared with RNP-positive SLE (OR = 0.1058 [95% CI = 0.02–0.546], p < 0.01) which was independent of the presence of Raynaud’s phenomenon, interstitial lung disease and disease duration. Presence of anti-U1RNP antibody is associated with notable patterns of microvascular abnormalities in SLE. These NFC abnormalities are noted more profoundly in patients with MCTD and are less marked in RNP-negative SLE patients.
Technology-assisted parent-mediated interventions improve accessibility and are acceptable but not proven to be effective. We conducted a systematic search of 6 databases. We included and analysed results from studies on social and communication outcomes. Sixteen Randomised-Controlled-Trials (RCTs) with 748 participants were included. Most studies were rated as of good quality. Meta-analysis suggested that interventions were probably effective in improving emotion recognition. No significant differences were found in social communication, social functioning or language outcomes. At present, isolated tech interventions do not fulfil criteria for promising or established evidence-based interventions for ASD. Future research needs to focus on improving the effectiveness of technology-assisted parent-mediated interventions for ASD. Prospero Registration Number: CRD42020162825.
There are not many studies looking at psychological impact of physical morbidities amongst patients with systemic sclerosis. Our aim was to describe the prevalence of common mental disorders (CMD) in systemic sclerosis patients, as against the population prevalence of CMDs. We also wanted to assess the utility of revised clinical interview schedule (CIS-R), a standardised interview technique for screening CMDs in systemic sclerosis (SSc). We prospectively recruited 93 consecutive patients fulfilling the 2013 ACR/EULAR criteria for systemic sclerosis from our single tertiary care centre. They were interviewed using CIS-R interviewing technique. These patients were assessed for the presence of psychiatric symptoms and presence of common mental disorders. Various associations of documented mental health issues and ICD-10-based psychiatric diagnosis were also analysed. A total of 29 (31%) out of 93 individuals with systemic sclerosis had a common mental disorder as per the earlier defined CIS-R cut off score of 12 and above. Fatigue (50.5%) and sleep issues (43%) were the commonest symptoms. Thirty-four patients (33.6%) fulfilled a total of 39 ICD-10 psychiatric diagnoses. Total CIS-R score is significantly associated with duration of Scleroderma in univariate analysis (p = 0.019), but there was no significant association on a multivariate analysis. Depression [18.3% as against 5% in Asian Indian general population], followed by obsessive compulsive disorder (OCD) [15.1% as against 0.7% in general population in India] were the top two ICD-10 psychiatric diagnosis in SSc. The occurrence of both depression and OCD, therefore, are far in excess compared to community prevalence. Additionally, modified CIS-R cut off of 10 instead of 12 can also improve the sensitivity (94%) of this screening interviewing tool for an ICD-10 psychiatric diagnosis. Depression is 3.4 times and OCD is 20 times commoner in our cohort of SSc than general population in India. A modified CIS-R cut-off score of 10 may further help in early recognition of these mental disorders in SSc and their referral to a psychiatrist.
Purpose: To audit the diagnostic accuracy of MRI for staging early and polyp rectal cancers with the purpose of identifying scope for service improvement. Methods : This is an IRB approved retrospective study of patients who underwent staging MRI for rectal growths followed by upfront TME type surgery or local excision without neoadjuvant therapy between 2018-21. MR-T stage was compared with surgical histopathology. The degree of stage migration in the multidisciplinary team meetings (MDT) was assessed and training needs were identified. Results : 53 patients (32 males) with a mean (SD) age of 56.7 (13.6) years with 54 rectal lesions and underwent trans-anal excision (n=18) or upfront surgery (n=35) were included. Pathology showed </=pT1 stage in n=18 and >/=pT2 stage in n=36. Radiopathological concordance rate was 38.9% and 74.1% respectively for primary reports and MDT reads respectively and during MDT, the rates improved by 44.5% and 30.5% for </=pT1 and >/=pT2 stages respectively. The overall T-stage migration rate at MDT was 44.6% (25/54) and the migration rate was higher (61.1%) for </=pT1 stage lesions. The best sensitivity, specificity, PPV, NPV and accuracy of MRI for T-staging was 83.3%, 91.6%, 83.3%, 91.6% and 88.8% respectively. Conclusion : Radio-pathological correlation for MRI T-stage is excellent for MDT reads by experienced radiologists. MDT reads lead to significant down-staging of T-stage in polyp and early rectal cancer thereby improving radio-path correlation.
Background Fused hips with spine stiffness in ankylosing spondylitis (AS) reduce spinopelvic mobility. We aimed to assess spinopelvic mobility pattern and acetabular anteversion in AS after total hip arthroplasty (THA). Material and methods Ninety-four stiff hips in 58 AS individuals (mean age: 37.05) who underwent THA between 2012 and 2018 with a modified lateral approach were included. Twenty-three hips were fused, and 71 hips had mean flexion of 37.67°. Pelvic tilt, pelvic inclination, sacral slope (SS), and lumbar lordosis were correlated with THA, and functional outcomes were assessed at 34.6-month mean follow-up. Results Thirty-seven had a stuck sitting pattern with stuck standing seen in 4 individuals. SS standing before and after THA were 25.08° and 27.30°. SS sitting was 8.99° compared to 16.80°. SS from sitting to standing was reduced (17.7°) in 17 individuals. Spine stiffness in extension was seen in 4 out of 37. Mean acetabular inclination after THA was 42.67°, and acetabular anteversion was 17.48°. Flexion after THA improved to mean 98.47°. Changes in SS from sitting to standing were correlated with THA (r-value: 0.93, P-value: .0001). The Harris Hip Score improved from 25.31 to 82.39 (P-value <.05), and the mean 12-item Short Form Survey at review was 52.18 and 59.55 (physical and mental components). The mean Western Ontario and Mc Master Universities Arthritis Index score was 17.56. Conclusions Spinopelvic mobility change was <10° after THA in AS, stuck sitting was seen in 37 of 58 (63.8%), and stuck standing was seen in 4 of 58 (6.9%), including spine stiffness in flexion or extension. Acetabular anteversion assessed was 17.48° (standard deviation: 4.41), with significant functional improvement. Level of Evidence Level 4.
