Background: Pancreatic trauma (PT) accounts for less than 1% of all trauma admissions. Occasionally, PT is undetected during theprimary survey and becomes apparent only when complications arise. It occurs in up to 5% of blunt abdominal trauma cases and 12%of individuals with penetrating abdominal injuries. Management is determined by the status of the main pancreatic duct and ***: This was an ambispective study conducted at the Jai Prakash Narayan Apex Trauma Center, All India Institute ofMedical Sciences,New Delhi, from January 2015 to December 2017 (retrospective), and January 2019 to December 2020 (prospective). In total, 113patients with PT were included in this ***:We analyzed the data of 113 patients with PT included in this study, of whichmales predominated (93.7%). Blunt PT was presentin 101 patients (89.4%) and penetrating PT in 12 patients (10.6%). Half of the patients (51.3%) had the American Association for theSurgery of Trauma grade III PT, followed by grade II (18.6%), and grade I (15%). Of the total 113 patients, 68 (60.2%) were treated withoperative management, and 45 (39.8%) with nonoperative management. Distal pancreatectomy, with or without splenectomy, was themost common procedure performed in our study, followed by drainage. There were 27 mortalities (23.8%) during the study period, ofwhich 7 were directly related to PT and 20 were due to other organ-related sepsis and hemorrhagic ***: Pancreatic trauma is rare but challenging for trauma surgeons, with persistent management controversies. Early diagnosisis important for favorable results;however, a delay in diagnosis has been associated with higher morbidity and mortality. Low-grade pancreaticinjuries can be successfully managed nonoperatively, whereas high-grade pancreatic injuries require surgical intervention.

Objectives: Central cord syndrome has been reported to occur with particular frequency among older persons with cervical spondylosis who sustain hyperextension neck injury. This study aims to determine the efficacy of early surgical decompression (within 24 hours) of traumatic central cord syndrome patients in comparison with conservative management for central cord syndrome to determine a line of management to these cases. Methods: 60 patients suffering from acute traumatic central cord syndrome with various neurological deficits were divided into 2 groups, group A (conservatively managed) and group B (surgically managed). Patients in group B were operated upon within 24 hr. of trauma by posterior decompression. Clinical assessment of each patient on admission, discharge and 3 months follow-ups was done using the ASIA Impairment Scale, FIM, Ashworth scale, bladder function, and neuropathic pain symptoms. Results: Data collected from both groups showed, group A (the conservative group) consisted of 22 male (73.3%) and 8 female subjects (26.6%) with a mean age of 57.5 years while in group B (surgical group) the sample consisted of 20 male (66.6%) and 10 female subjects (33.3%) with a mean age of 58.6 years. There was an improvement in our study—according to ASIA and FIM scales—in 8 patients of 30 (26.6%) in the conservative group. In the surgical group, improvement in 16 patients (53.3%). Conclusions: Early surgical decompression with laminectomy and duroplasty can be considered a reliable modality in the management of traumatic CCS and can effectively reduce the secondary injury of the spinal cord and consequent deterioration with less hospital stay.

Background: Epilepsy is one of the most common neurological conditions with about 65 million people affected worldwide. It is also a common condition in children, where its prevalence is approximately 3.2 - 5.5/1000 in the developed world. Children with epilepsy (CWE) experience not only seizures but also multiple cognitive, behavioral, and emotional problems. ADHD is one of the more common comorbidities of childhood epilepsy. Objectives: To discuss the relationship between childhood epilepsy and comorbidities especially ADHD. Study Design: This is a prospective observational analytical cross-sectional study carried out on one hundred and fifteen patients at Ain Shams University and Nasr-city Health Insurance out-patient clinics, Cairo, Egypt fulfilling the inclusion criteria. Patients were selected by simple random sample. Results: ADHD is very common epilepsy comorbidity in Egyptian epileptic children with under-diagnosis and treatment. Conclusion: Frequent assessment for ADHD in epileptic children is mandatory for better quality of life.

Two-dimensional(2 D) Te nanosheets were successfully fabricated through the liquid-phase exfoliation(LPE) method. The nonlinear optical properties of 2 D Te nanosheets were studied by the open-aperture Z-scan technique. Furthermore, the continuous wave mode-locked Nd:YVO4 laser was successfully realized by using 2 D Te as a saturable absorber(SA) for the first time, to the best of our knowledge. Ultrashort pulses as short as 5.8 ps were obtained at 1064.3 nm with an output power of 851 m W. This primary investigation indicates that the 2 D Te SA is a promising photonic device in the fields of ultrafast solid-state lasers.
