This study aimed at evaluating the medial approach for open reduction and internal fixation of Gartland type 3 displaced supracondylar fractures of humerus in children. A prospective, single centre study of on displaced supracondylar humerus fractures in 42 children was carried out at our institute. All fractures were managed with open reduction and internal fixation with crossed K-wires via medial approach. The mean follow-up was 12 months and patients were assessed according to Flynn's criteria. No patients had post-operative ulnar nerve injury. Cubitus varus was not seen in any patient. Superficial pin tract infection occurred in three patients that subsided with anti-septic dressings and antibiotics. No deep infection occurred. 88.09 % patients showed satisfactory results as per Flynn's criteria. The medial approach provides an excellent view of the supracondylar area. The approach is convenient due to a lower risk for ulnar nerve injury and better acceptability of the medial incisional scar.

Fractures of the skull base are relatively common. They have been reported to occur in 3.5?24.0 percent of head injury patients. This wide variation results from differences in studied patient populations and from difficulty of obtaining radiographic verifications of the fracture.1 The Traumatic Coma Data Bank in a prospective series of severe head injury reported that 25% had basilar skull fractures.2 In this paper we analyze the various types of fractures and their management.

Object This study was conducted both prospectively and retrospectively at one center over a period of 8 years. The population consisted of all patients with both an age 18 years or younger and a diagnosed penetrating missile injury (PMI) during the study interval. The authors analyzed factors determining outcome and demographic trends in this population, and they compared them with those in the more developed world Methods Fifty-one patients were the victims of armed conflict, although no one was directly a party to any battle. This mechanism of injury is in strong opposition to data in the literature from developed countries, in which most missile injuries are the result of suicide or homicide or are even sports related. Moreover, all previous studies on the pediatric population have considered only injuries from gunshots, but authors of the current study have included injuries from other penetrating missiles as well. Results On cross tabulation analysis using the chi-square test, the factors shown to correlate with outcome included the Glasgow Coma Scale (GCS) score, pupillary abnormalities, patient age, hemodynamic status, and bihemispheric damage. On multinomial regression analysis, the two strongest predictors of death were GCS score and pupillary abnormalities. The GCS score and hemodynamic status were the strongest predictors of disability. Conclusions There was no difference in the prognostic factors for PMI between developing or more developed countries. Glasgow Coma Scale score, pupillary abnormalities, and hemodynamic status were the strongest predictors of outcome. In conflict zones in developing countries the victims were mostly innocent bystanders, whereas in the more developed countries homicides and suicides were the leading etiological factors.

RFID (radio-frequency identification) technology is rapidly emerging for the localization of moving objects and humans. Due to the blockage of radio signals by the human body, the localization accuracy achieved with a single tag is not satisfactory. This paper proposes a method based on an RFID tag array and laser ranging information to address the localization of live moving objects such as humans or animals. We equipped a human with a tag array and calculated the phase-based radial velocity of every tag. The laser information was, first, clustered through the DBSCAN (Density-Based Spatial Clustering of Applications with Noise) algorithm and then laser-based radial velocity was calculated. This velocity was matched with phase-based radial velocity to get best matching clusters. A particle filter was used to localize the moving human by fusing the matching results of both velocities. Experiments were conducted by using a SCITOS G5 service robot. The results verified the feasibility of our approach and proved that our approach significantly increases localization accuracy by up to 25% compared to a single tag approach.

Objectives: The aim of this study was to assess the head injury in children caused by an unusual projectile, a tear gas cartridge. The study is the only one on this subject which has been done in a teenage population. Method: This was a prospective study conducted over a period of 4 years in which all the patients aged less than or equal to 18 years and who had a head injury due to a tear gas cartridge were included. Results: We had 5 patients in our study group. All the patients were males. Commonest CT scan finding was brain contusion with skull fracture. One of our patients died. One patient continues to be in vegetative state whereas 3 had a good outcome. Conclusion: Tear gas cartridge, though considered as one of the benign modalities of controlling agitated crowds, is not really benign. It can cause serious injuries and mortality. The personnel using them might be trained in a better way so that the people do not receive direct hits. In addition some changes in the design of tear gas cartridge can be done to decrease the impact to the skull.
