RESUMEN
Background: Cancer incidence is rising across the globe. The incidence and patterns of various cancers among Armed Forces Personnel and Veterans is not known. We did the analysis of registry data maintained at our hospital. Methods: A retrospective analysis was performed of all patients registered at our hospital cancer registry between 01st January 2017 and 31st December 2019. Patients were registered with unique identification number. Baseline demographics and cancer subtype data were retrieved. Patients with histopathologically proven diagnosis and age ≥18 years were studied. Armed Forces Personnel (AFP) were defined as those who are in active service, and Veterans as those who had retired from service at the time of registration. Patients with Acute and Chronic Leukemias were excluded. Results: New cases registered were 2023, 2856 and 3057 in year 2017, 2018, 2019 respectively. AFP, Veterans and dependents among them were 9.6%, 17.8%, and 72.6% respectively. Haryana, Uttar Pradesh and Rajasthan represented 55% of all cases with male to female ratio 1.14:1 and median age was 59 years. The median age among AFP was 39 years. Among AFP as well as veterans, Head and Neck cancer was the most common malignancy. Cancer incidence was significantly higher in adults >40 years as compared to <40 years. Conclusion: Seven percent rise per year of new cases in this cohort is alarming. Tobacco-related cancers were the most common. There is an unmet need to establish a prospective centralized Cancer Registry to better understand the risk factors, outcomes of treatment and strengthen the policy matters.
RESUMEN
Seed germination characteristics help predict the degree of invasive success of a species based on capacity of the seeds to germinate and recruit into novel habitats. Hyptis suaveolens (L.) Poit. (Bush mint, Pignut; Lamiaceae) is an invasive plant that is spreading throughout tropical and subtropical regions worldwide. We conducted a study to understand the role of seed size dimorphism in differentiation of germination niche in H. suaveolens. We subjected small and large seeds to varying environmental conditions of temperature (°C), photoperiod (light/dark), salt (NaCl; mM), pH, osmotic potential (MPa), different soil types and ratios (clay:sand) and burial depth (cm). Different germination indices were calculated and their interaction with seed dimorphism studied. There was a significant interaction (P < 0.001) between germination indices and seed dimorphism throughout the treatments. Large seeds had higher germination percentage and rate, indicating higher germination capacity. In addition, these displayed more asynchronous germination under various environments. Small seeds, on the other hand, required a longer germination time as compared to large seeds, indicating slower germination. Differential responses of the two seed morphs to varying environmental conditions, therefore, help H. suaveolens to differentiate its germination niche and establish in heterogeneous environments. These findings will help in devising appropriate management and eradication strategies based on germination ecology of seeds.

In this case report we describe a rare case of chondrosarcoma of the Temporomandibular joint in a 70 years old female who presented with a right preauricular swelling, trismus and neuralgic pain. On examination, firm and tender swelling was noted in the right preauricular region. CT Scan revealed 3.48 × 3.0 cm size mass lesion in the region of mandibular condyle and extending into the right temporomandibular joint space. The cytopathological report was suggestive of chondroid malignancy. The tumor was excised and histopathological examination showed large sheets of atypical tumor cells with cartilaginous matrix and diagnosis of a well differentiated Chondrosarcoma was confirmed. Post-surgical resection, patient remains disease free at 15 months follow up.
RESUMEN
Various anaesthetic agents have been used in dentistry for the extraction of teeth. The most commonly used local anaesthetic agent is lidocaine hydrochloride. Recently, articaine hydrochloride came into existence because of its versatile properties and longer duration of action. Due to lack of study of effects of articaine on various systems, the present study is aimed to compare the anaesthetic efficacy of articaine and lidocaine with adrenaline during the extraction of mandibular molars. A total of 100 patients was randomly divided into two groups (50 each) and clinical variables such onset and duration of anaesthesia, blood pressure, oxygen saturation, pulse rate, and pain perception were recorded at different time intervals using a visual analogue scale. The statistical analysis was performed using SPSS version 22.0. Mean and standard deviations, frequency distribution analysis, and the chi squared test were performed to calculate variables and a p< 0.05 was considered significant. Statistically significant differences were obtained regarding mean time of onset of anaesthesia (p< 0.001), mean duration of the anaesthetic effect (p< 0.001), and pain perception for the articaine group. No significant results were obtained for blood pressure, oxygen saturation, or pulse rate. During the deposition of articaine, patients reported less pain than with lidocaine. Articaine hydrochloride helped to achieve increased anaesthetic success in dental applications over lidocaine hydrochloride in terms of fast time of onset, longer duration, and less pain, all of which were attributed to its greater diffusion properties.

Chronic suppurative otitis media in almost any form can disrupt the integrity of ossicular chain. Various materials have been used for ossicular substitution or reconstruction, including both biologic and alloplastic materials. Teflon piston is now the most widely used prosthesis for reconstruction of the ossicular chain in cases of otosclerosis. The oto-surgeons are still confronted with problems of ossicular reconstruction regarding the surgical procedure to be done, type of graft to be selected especially in low and poor socioeconomic population. Thus, there is a need felt to comprehensively and holistically evaluate the outcome of ossiculoplasty using Autograft ossicle versus Allograft ossicle (Teflon). Total 64 patients of chronic suppurative otitis media with no active ear infection and air-bone-gap of more than 15 dB were admitted for surgery and divided into two groups according to material used for ossiculoplasty as group A (Autograft) and group B (Allograft). Patients were evaluated at 3 and 6 months post-operatively using audiogram. In both Group A and B, the average pre-operative AC was 40.62 dB (SD 9.65) and 39.37 (SD 10.53) respectively. In 3 months there was a change of 8.83% from 40.62 dB to 37.03 dB in Group-A (p < 0.109, not statistically significant) and 13.10% change from 39.37 dB to 34.21 dB in Group-B (p < 0.049, statistically significant) whereas at 6 months, air conduction improved by 14.22% in Group-A (p < 0.01, statistically significant) and by 21.81% in Group-B (p < 0.001, highly statistically significant). Post-operatively at 3 months, improved AB gap was 62.5% in Group-A and 68.75% in Group-B patients. Post-operative AB gap at 6 months, improvement was seen in 78.12% in Group-A while it was 81.25% in Group-B patients. Alloplastic Teflon ossicle appears to be a good alternative for ossicular reconstruction where autologous incus is not available or disease precludes its use.

RESUMEN
Background/Purpose Many treatment options are available for wrist osteoarthritis, with the objective of decreasing pain and preserving function. In later stages when midcarpal and radiocarpal osteoarthritis occur, two choices remain: total wrist arthrodesis or total wrist arthroplasty. The purpose of this study is to present the short-term functional changes following total wrist arthroplasty with the Universal 2 total wrist system (Integra Life Sciences) in patients with noninflammatory wrist osteoarthritis. Patients and Methods Patients with severe noninflammatory wrist osteoarthritis were assessed preoperatively, 6 and 12 months after surgery using a range of motion, grip strength, pain, and the disabilities of the arm, shoulder, and hand (DASH) score. The additional assessment was performed after 1 year for a range of motion using a biaxial electrogoniometer, grip strength, DASH, and the Michigan hand questionnaire. Results All range of motion directions and grip strength did not change from preoperative values. The DASH score improved from 53 preoperatively to 14 during latest follow-up. Median patients' satisfaction score decreased with approximately 20 points during the last follow-up. Conclusion The relatively good DASH score combined with the partly maintained wrist range of motion indicates that reconstruction with the Universal 2 total wrist prosthesis should be considered in patients with end-stage noninflammatory wrist osteoarthritis. Level of Evidence Level IV, therapeutic study.
RESUMEN
Our aim was to assess the outcome in patients with total wrist arthroplasty performed for end stage wrist osteoarthritis. We analysed the ranges of motion of operated and un-operated wrists using a flexible electrogoniometer during the Sollerman hand function test. We assessed grip strength with a digital dynamometer and completed patient reported outcome scores more than one year post-operatively. We reviewed 12 patients with a mean age of 64 (range 48-82) years. The flexion-extension arc was 72% and radioulnar deviation arc was 53% of the un-operated side but the total range of motion (area of circumduction) was 43% of the un-operated side and only 20% of the circumduction in age and gender-matched normal volunteers. Peak grip strength was 68% of the un-operated side. The patients reported good outcome with mean Michigan Hand Questionnaire (MHQ) scores of 56 (range 25-84) and mean Patient Evaluation Measure (PEM) scores of 39 (range 20-68). Patients completed the activities of Sollerman hand function test in twice the time (6 min) as required for a normal volunteer (2.8 min). The circumduction ellipses were narrow and central with limited radio-ulnar deviation and small mean areas of motion during activities of daily living.

Proximal row carpectomy and four-corner fusion are commonly used in the patients with scaphoid nonunion advanced collapse or scapholunate advanced collapse. We compared activities of daily living of the 24 patients after proximal row carpectomy with 24 patients with four-corner fusion procedures using the modified Sollerman hand function test and Michigan Hand Questionnaire. Most tasks were performed significantly quicker by the patients after proximal row carpectomy. The patients after proximal row carpectomy reported better function during activities of daily living. LEVEL OF EVIDENCE: Level III, Therapeutic Study.
RESUMEN
Our aim was to evaluate the efficacy of clonidine with lidocaine as a local anaesthetic agent for inferior alveolar mandibular nerve blocks for dental extraction. We studied 200 patients who required extraction of mandibular teeth and divided them into two groups of 100 each, the first of which was given lidocaine and adrenaline (12.5µg/ml) and the second lidocaine and clonidine (15µg/ml). Cardiovascular vascular variables (blood pressure, heart rate, and mean arterial pressure) were assessed before, during, and after extraction, and postoperative pain was measured on a visual analogue scale. There was a significant reduction in systolic blood pressure (p=0.0001) and heart rate (p=0.000) after injection of clonidine. However, they both increased after injections of lidocaine plus adrenaline, and there was a significant reduction in pain at four hours postoperatively with clonidine (p=0.000). Our results showed that anaesthesia with lidocaine and clonidine decreases systolic blood pressure and heart rate 10minutes after injection for extraction of lower mandibular teeth. We suggest that patients who have local anaesthetic with lidocaine and clonidine are at minimal cardiovascular risk and there is no difference in the onset of anaesthesia.

OBJECTIVE: A possible role of the APC/beta-catenin pathway in the pathogenesis of sporadic juvenile nasopharyngeal angiofibroma has been suggested. This paper presents its current status and clinical association in our patients. METHOD: A prospective observational study was conducted at King George Medical University and Central Drug Research Institute, in Lucknow, India. Western blot analysis was undertaken in 16 cases to examine beta-catenin expression. The clinical details were recorded along with follow up observations, to determine associations. RESULTS: Up-regulation of beta-catenin expression was seen in 69 per cent of cases. The clinical variables did not reveal significant differences between patients with extremes of expression (extreme under- vs over-expression). However, absent expression was shown exclusively in young adults aged over 18 years, while enhanced expression was associated with an altered facial profile. CONCLUSION: Although a beta-catenin association was seen in a subset of our sporadic juvenile nasopharyngeal angiofibroma cases, its expression was not homogeneous. This is in contrast to the Western literature that suggests a universal (homogenous) enhanced expression in the majority. Hence, further research is required to better define its molecular cascade.

OBJECTIVE: To study the association between fundal changes (malarial retinopathy) and mortality in children with cerebral malaria. METHODS: 50 consecutive children (mean age 8.4 y, 23 males) with cerebral malaria (acute febrile encephalopathy and either peripheral smear or Rapid diagnostic test positive for malaria) were evaluated by a single ophthalmologist for any changes of retinopathy. Children were managed as per standard guidelines for treatment of cerebral malaria. RESULTS: P. vivax infection was seen in one child, P. falciparum infection in 42 children, and a mixed infection in 7. Retinopathy was present in 48% of the children. 13 children died during hospital stay. The mean interval from admission to fundus examination was 11.6 (4.64) h. Presence of any retinopathy (P=0.02), and either of papilledema (P=0.02), hemorrhages (P=0.005) or vessel changes (P=0.01), were associated with a significantly higher risk of death. CONCLUSION: Malarial retinopathy is significantly associated with mortality in children with cerebral malaria. It may be used for both prognostication, and triaging for optimum utilization of intensive care facilities in these children.

The patient underwent trans-cervical complete excision of the tumour. Postoperatively, patient did well without recurrence or metastasis for 2 years follow up.
RESUMEN
BACKGROUND: Juvenile nasopharyngeal angiofibroma often presents with lateral extensions. In countries with limited resources, selection of a cost-effective and least morbid surgical approach for complete excision is challenging. METHODS: Sixty-three patients with juvenile nasopharyngeal angiofibroma, with lateral extensions, underwent transpalatal, transpalatal-circumaxillary (transpterygopalatine) or transpalatal-circumaxillary-sublabial approaches for resection. Clinico-radiological characteristics, tumour volume and intra-operative bleeding were recorded. RESULTS: The transpalatal approach was suitable for extensions involving medial part of pterygopalatine fossa; transpalatal-circumaxillary for extensions involving complete pterygopalatine fossa, with or without partial infratemporal fossa; and transpalatal-circumaxillary-sublabial for extensions involving complete infratemporal fossa, even cheek or temporal fossa up to zygomatic arch. Haemorrhage was greatest with the transpalatal-circumaxillary-sublabial approach, followed by transpalatal approach and transpalatal-circumaxillary approach (1212, 950 and 777 ml respectively). Tumour size (volume) was greatest with the transpalatal-circumaxillary approach, followed by transpalatal-circumaxillary-sublabial approach and transpalatal approach (40, 34 and 29 mm3). There was recurrence in three cases and residual disease in two cases. Long-term morbidity included small palatal perforation (n = 1), trismus (n = 1) and atrophic rhinitis (n = 2). CONCLUSION: These modified techniques, performed with endoscopic assistance under hypotensive anaesthesia, without embolisation, offer a superior option over other open procedures with regard to morbidity and recurrences.

This study aims to identify the patterns of dominance of extrinsic or intrinsic muscles in finger flexion during initiation of finger curl and mid-finger flexion. We recorded 82 hands of healthy individuals (18-74 years) while flexing their fingers and tracked the finger joint angles of the little finger using video motion tracking. A total of 57 hands (69.5%) were classified as extrinsic dominant, where the finger flexion was initiated and maintained at proximal interphalangeal and distal interphalangeal joints. A total of 25 (30.5%) were classified as intrinsic dominant, where the finger flexion was initiated and maintained at the metacarpophalangeal joint. The distribution of age, sex, dominance, handedness and body mass index was similar in the two groups. This knowledge may allow clinicians to develop more efficient rehabilitation regimes, since intrinsic dominant individuals would not initiate extrinsic muscle contraction till later in finger flexion, and might therefore be allowed limited early active motion. For extrinsic dominant individuals, by contrast, initial contraction of extrinsic muscles would place increased stress on the tendon repair site if early motion were permitted.
