Is the outcrop topology of dolerite dikes of the Precambrian Singhbhum Craton fractal?

In the Precambrian Singhbhum Craton of eastern India, newer dolerite dikes occur profusely with varying outcrop lengths. We have analysed the nature of their length-size and orientation distributions in relation to the theory of fractals. Two orientational sets of dikes (NW-SE and NE-SW) are present. Both the sets show strongly non-power-law size distributions, as reflected in non-linear variations in logarithmic space. We analyzed thousands of data, revealing that polynomial functions with a degree of 3 to 4 are the best representatives of the non-linear variations. Orientation analysis shows that the degree of dispersions from the mean trend tends to decrease with increasing dike length. The length-size distributions were studied by simulating fractures in physical models. Experimental fractures also show a non-power-law distribution, which grossly conforms to those of the dolerite dikes. This type of complex size distributions results from the combined effects of nucleation, propagation and coalescence of fractures

Tuberculous Osteomyelitis of the Patella 髕骨結核性骨髓炎：病例報告

AbstractPatellar tuberculosis is a rare occurrence despite the knee being the third most common osteoarticular site to be involved. This is the reason for its late diagnosis and the potential to spread posteriorly to the knee. We present an atypical case of patellar tuberculosis in an 8-year-old boy presenting with discharging sinus and diagnosed by biopsy

Intra articular distal radius fractures and volar plate fixation: a prospective study

Background: Despite being one of the most common fractures encountered in patients, intra-articular distal radius fractures still pose therapeutic challenge to Orthopaedic surgeons. With the advent of locking plates, the fixation of these fractures has been made better, specifically by fixed angle volar locking plate. This study investigates the efficacy of these plates using volar approach, functional and clinical outcome, in addition to the radiological alignment.Methods: Thirty patients with closed distal radius fractures, with AO TYPE B3, B4, AND C fracture pattern, operated with distal radius plate fixation using volar approach, were included in the study during the period of August 2014 to August 2016. With a minimum follow up of six months, radiological outcome was analysed and functional outcome recorded (Gartland and Werley’s demerit scoring system).Results: With a mean age of 42 years and follow up of six months, the range of movement of the wrist was very satisfactory, and the mean grip strength was 80% of the opposite wrist. Radiological parameters were well‑maintained, and functional parameters by Gartland and Werley showed a significant improvement in most of the patients during the follow‑up period. The complication rate was less and insignificant.Conclusions: Primary volar plate fixation of intraarticular distal radius fracture provides a stable construct that helps in early mobilization, thereby better functional outcomes and minimizes chances of delayed/malunion

Anthropometric Study of Nasal Parameters of South Indian Population

Introduction The shape of the nose is a signature indicating the ethnicity, age, and sex of the person. Our aim is to map the range of various anthropometric parameters of nose in South Indians. Materials and Methods This study includes measurement and statistical analysis of different parameters of nose among 61 South Indian medical students (34 females;27 males) using digital Vernier calipers. Results The means of various parameters were- 1) Nasal Breadth -2.9cm (males) and 2.5 cm (females). 2) Nasal height-5 cm (males) and 4.9cm (females). 3) The nasofacial angle-37.9 degree (males) and 36.7 degree (females). 4) The nasolabial angle 115.2 degree (males) and 116.5 degree (females). 5) The nasofrontal angle 127.1 degree (males) and 134.7 degree (females). 6) The most common type of nose is leptorrhine in both males and females. Conclusion All the measurements can be used for evaluation of nasal deformity, treatment planning and post-surgical evaluation of the correction achieved during rhinoplasty

Influence of integrated nutrient management on physiological parameters of lentil (Lens culinaris Medik.)

During the rabi season of 2021, a field experiment was conducted in the North Western plains of Uttarakhand at Crop Research Centre, School of Agriculture, Uttaranchal University, Dehradun to examine the impact of integrated nutrient management (INM) on lentil growth, yield, and economics (Lens culinaris Medik.). The experiment was laid in Randomized Block Design with seven treatments i.e. T1 (Control, 100% RDF (Recommended Dose of Fertilizers), T2 (75 % NPK (Nitrogen, Phosphorus, Potassium) + 25 % FYM (Farm Yard Manure), T3 (50 % NPK + 50 % FYM), T4 (75 % NPK + 25 % Azotobacter), T5 (50 % NPK + 50 % Azotobacter), T6 (75 % NPK + 25 % (Vermicompost + Azotobacter)) & T7 (50 % NPK+ 50 % (Vermicompost + Azotobacter)). The treatments T7 with the combination of 50 per cent NPK and 50 per cent vermicompost plus Azotobacter showed maximum LAI (Leaf Area Index) (0.25), NAR (Net Assimilation Rate) (0.0020), chlorophyll content (3.05), dry matter (4.44 g), and protein content (26.99 %) in contrast to other six treatments

Unidentified bright objects of spleen on arterial phase CT: mimicker of splenic vascular injury in blunt abdominal trauma

PURPOSEWe have described unidentified bright objects of spleen (UBOS), a hitherto undescribed entity, as hyperdense areas on arterial phase (AP) computed tomography (CT) seen in relation to splenic lacerations and are isodense to the normal parenchyma on portal venous phase with no correlate on digital subtraction angiography (DSA). UBOS mimic splenic vascular injuries like active contrast extravasation and pseudoaneurysm and need to be differentiated from them as it would have implications on patient management. We undertook this study to identify CT features of UBOS that can differentiate them from splenic vascular injuries and to calculate their diagnostic accuracy.METHODSThis retrospective study was approved by the institutional ethical committee and the need for informed consent was waived. Patients with splenic injury who had undergone dual-phase CT and DSA were included. All the lesions that were hyperdense on AP were evaluated for their outline, their relation to the adjacent/parallel margins of a laceration (margin sign), string of beads appearance, and the presence of adjacent normal parenchyma (adjacent parenchyma sign). The Hounsfield unit (HU) of the lesion and the aorta on the AP were also noted. The diagnostic accuracy of various signs for distinguishing UBOS from splenic vascular injuries was calculated using DSA as the reference standard.RESULTSOf 48 patients, 5 were excluded due to suboptimal quality of the examination or a time difference of more than 6 hours between the CT and DSA. A total of 54 hyperdense lesions were detected on AP in 43 patients. These were classified as vascular injuries (pseudoaneurysm, n=11; active contrast extravasation, n=11) and UBOS (n=32) based on DSA. The margin sign, string of beads appearance, and ill-defined outline had high specificity (95%, 86%, and 82%, respectively) but low sensitivity (50%, 65%, and 63%, respectively). The adjacent parenchyma sign had a moderate sensitivity and specificity of 84% and 77%, respectively. ROC analysis showed that a difference of 50 HU between the aorta and the lesion had a high sensitivity and specificity of 88.9% and 90.6%, respectively, with an area under the curve of 0.90.CONCLUSIONAn attenuation difference of over 50 HU between the aorta and the lesion and the presence of normal adjacent parenchyma had the highest diagnostic accuracy, while an ill-defined outline, string of beads appearance, and margin sign had high specificity but low sensitivity for differentiating UBOS from splenic vascular injuries

Traumatic diaphragmatic injury: a review of CT signs and the difference between blunt and penetrating injury

PURPOSE:We aimed to present the frequency of computed tomography (CT) signs of diaphragmatic rupture and the differences between blunt and penetrating trauma. MATERIALS AND METHODS:The CT scans of 23 patients with surgically proven diaphragmatic tears (both blunt and penetrating) were retrospectively reviewed for previously described CT signs of diaphragmatic injuries. The overall frequency of CT signs was reported; frequency of signs in right- and left-sided injuries and blunt and penetrating trauma were separately tabulated and statistically compared. RESULTS:The discontinuous diaphragm sign was the most common sign, observed in 95.7% of patients, followed by diaphragmatic thickening (69.6%). While the dependent viscera sign and collar sign were exclusively observed in blunt-trauma patients, organ herniation (P = 0.05) and dangling diaphragm (P = 0.0086) signs were observed significantly more often in blunt trauma than in penetrating trauma. Contiguous injury on either side of the diaphragm was observed more often in penetrating trauma (83.3%) than in blunt trauma (17.7%). CONCLUSION:Knowledge of the mechanism of injury and familiarity with all CT signs of diaphragmatic injury are necessary to avoid a missed diagnosis because there is variability in the overall occurrence of these signs, with significant differences between blunt and penetrating trauma
