An analysis of LULC changes for understanding the impact of anthropogenic activities on food security: a case study of Dudhganga watershed, India.

Although the Dudhganga watershed is the primary water and food resource of the Kashmir Valley, it has undergone significant changes in food resources and strategies due to rampant urbanization in the area over the past 20 years. This urbanization has had a profound impact on the watershed and has also affected land use and land cover (LULC) patterns and environmental changes. The objective of this study is to investigate the effects of urban development on food security parameters in the Dudhganga watershed area, India, from 2000 to 2020, by evaluating LULC changes. Additionally, the study aims to examine the relationship between climate changes and LULC indices, such as the Modified Normalized Difference Water Index (MNDWI), Normalized Difference Vegetation Index (NDVI), and Normalized Difference Built-up Index (NDBI). The results indicate a 21.66% increase in barren areas, at the expense of snow-covered lands, during the 2000-2020 period. The primary land cover transition observed is towards barren areas. The predictions for LULC in 2030 highlight the need for careful management of land use and climate changes in the study area. This study can assist local government officials in reassessing food strategies by identifying areas where urban expansion should be controlled and climate impacts minimized, to prevent local hunger and ecological degradation. Therefore, the development of systematic urban planning approaches and mitigation of climate change sources are crucial. Furthermore, the adoption of advanced agricultural technology should be considered to mitigate the impact of urban expansion.

Interpretation of computed tomography of the cervical spine by non-radiologists: a systematic review and meta-analysis.

BACKGROUND: After trauma, clearance of the cervical spine refers to the exclusion of underlying serious injuries. Accurate assessment of computed tomography (CT) is commonly required prior to clearance of the cervical spine. Delays to clearance can lead to prolonged immobilization with associated patient discomfort and adverse effects. This systematic review aimed to determine performance of non-radiologists to evaluate cervical spine CT. METHODS: MEDLINE, EMBASE, Cochrane library with sources of grey literature and reference lists of selected articles were appraised from inception to April 2021. We included manuscripts that reported discordance in CT cervical spine interpretation between non-radiologists and radiologists. The Newcastle-Ottawa scale (NOS) was used to assess quality of included studies and statistical heterogeneity was assessed using the I2 statistic. RESULTS: There were 43 studies identified for eligibility and 4 manuscripts included in the final analysis. There were two studies that reported on the performance of radiology residents, one study on the performance of surgical residents and one on emergency physicians. The pooled discordance was 0.25 (95%CI 0.21-0.28) but was lower for radiology residents (range 0.007-0.05). There was significant statistical heterogeneity (I2  = 99.6%, P < 0.001) among studies. CONCLUSION: There is a paucity of evidence documenting the ability of non-radiologists in accurately interpreting CT of the cervical spine. A number of discordant findings suggest that studies with larger sample sizes are indicated to accurately ascertain the ability of non-radiologists in this area.

Diagnostic utility of CT enterography in the evaluation of ileocecal mucosal lesions of uncertain diagnosis on ileocolonoscopy.

Purpose: Ileocolonoscopy aids in the diagnosis of ileocecal region pathologies when typical mucosal lesions are seen. However, in many cases the mucosal lesions of the ileocaecal region are atypical, rendering themselves to diagnostic dilemma. The present study aimed to study the role of computed tomography (CT) enterography in the evaluation of symptomatic patients who demonstrated ileocecal mucosal lesions of uncertain diagnosis on ileocolonoscopy. Material and methods: Symptomatic patients who had ileocolonoscopy documented ileocecal mucosal lesions of uncertain diagnosis were enrolled. Patients were subjected to CT enterography within 10 days of ileocolonoscopy. On CT enterography a diagnosis of Crohn's disease (CD) or ileocaecal tuberculosis (ITB) was made. The diagnosis obtained by CT enterography was correlated with the final diagnosis obtained from histopathology. Using descriptive statistics, the diagnostic performance of CT enterography was evaluated. Results: A total of 153 cases were enrolled in the study. CT enterography findings were present in 147 cases, resulting in a diagnostic yield of 96%. Out of these, 58.16% (89/153) had CD, 26.14% (40/153) had ITB, 6.5% (10/153) had infectious ileitis, and 9.15% (14/153) were indeterminate on histopathology. CT enterography correctly identified 78.65% (70/89) of CD and 75% (30/40) of ITB. CT enterography had a sensitivity of 78.65% and 75%, specificity of 67.19% and 87.61%, positive predictive value of 76.92% and 68.18%, and diagnostic accuracy of 73.86% and 84.31% for diagnosing CD and ITB, respectively. Conclusions: CT enterography provided a high diagnostic yield in ileocaecal mucosal lesions of uncertain significance on endoscopy. CD and ITB were the predominant diseases detected in these individuals. CT enterography had a good diagnostic performance in the detection of these 2 disorders.

Indirect Arthroscopic Distal Clavicle Resection: an Institutional Experience with Midterm Functional Outcome.

BACKGROUND: Acromioclavicular joint arthritis is a relatively common source of shoulder pain. The treatment options consist of conservative management and operative intervention depending on the severity and duration of the disease. Distal clavicle excision is the standard operative treatment and can be performed through either open or arthroscopic techniques. The purpose of this study was to evaluate the functional outcome of arthroscopic resection of the distal clavicle. MATERIAL AND METHODS: This was a prospective study, conducted in a group of 50 patients in the Post-Gra-duate Department of Orthopaedics, Govt. Medical College Srinagar, from July 2015 to July 2019 with cases followed for a minimum of 3 years. RESULTS: The mean UCLA score improved from 13.2 preoperatively to 29.56 at final follow-up. An excellent result was seen in 10 patients (20%), good in 34 (68%), fair in 3 (6%) and poor in 3 (6%) patients. Overall 88% of the patients achieved excellent or good results and 94% were satisfied. Persistent pain and excessive intraoperative bleeding were the most common complications in our study. CONCLUSIONS: 1. Distal clavicle excision through an indirect or subacromial approach is a safe and effective procedure with very few complications. 2. The subacromial approach gives the added advantage of evaluating any glenohumeral joint and subacromial pathology. 3. This procedure is associated with less pain and improved cosmesis in comparison to open procedures.

Central angioleiomyoma of the mandible: A rare entity.

The leiomyoma is a benign smooth-muscle neoplasm commonly found in the female genital tract, gastrointestinal tract, or skin. Leiomyomas of the oral cavity are unusual. Oral leiomyomas are uncommon due to the paucity of the smooth muscle in the mouth (except in blood vessels) and thus the involvement of jaw bones is extremely rare. Leiomyomas have been classified as solid angiomyoma, angioleiomyoma (vascular leiomyoma), and epithelioid variants. Angioleiomyomas are benign mesenchymal tumors derived from smooth muscle, which rarely occur in the oral cavity. Malignant transformation probably does not occur but careful histopathologic examination is still necessary to differentiate these benign lesions from their malignant counterparts due to different prognosis. Although uncommon in the maxilla and mandible, they should be included in the differential diagnosis of radiolucent lesions of jaw bones. An extensive search of literature was carried out on the Medline-PubMed and Google Scholar database using the keywords such as leiomyoma, angioleiomyoma, jaw bones, maxilla, mandible, intra-osseous to thoroughly search and collect all the reported cases of intraosseous leiomyoma (but our search was not limited to these terms only). To the best of our knowledge, only 23 cases of intraosseous leiomyomas have been reported so far in the jaw bones, among which only 8 belonged to angioleiomyomas. Herein, we report the 9th case of intraosseous angioleiomyoma, one of the variants of leiomyoma and overall 24th intraosseous leiomyoma in a 6-year-old female child, together with conventional histopathologic and immunohistochemical findings.

Isolated angiokeratomas of the tongue: A rare entity.

Angiokeratomas consist of ectasias of dermal capillaries associated with an acanthotic and hyperkeratotic overlying epidermis. These dark red-to-purple, papular vascular anomalies can vary considerably in size, depth, and location. It is a skin disorder that rarely involves oral cavity. It can occur in localized or generalized form and is often associated with underlying metabolic disorder such as Fabry's disease and fucosidosis. It has many clinical variants with the same underlying histopathology. Mucosal involvement, including the oral cavity, is occasionally found either as a component of the systemic variety, called angiokeratoma corporis diffusum, or associated with cutaneous lesions in more locations. Isolated oral involvement seems to be rather infrequent, and only eighteen cases have been described in the world literature thus far. Isolated multiple angiokeratomas of tongue without plaque formation have been reported only four times before this. Here, we report a fifth case of isolated multiple angiokeratomas of tongue in a 16-year-old female which was confirmed by immunohistochemical pattern in consonance with a blood vessel origin, with expression of CD31, CD34, and von Willebrand factor. The lesion did not express D2-40 and CD45. No other malformation or metabolic disorder was found in the patient.
