Introduction: Neisseria meningitidis (N. meningitidis) is associated with severe invasive infections such as meningitis and fulminant septicemia. Septic arthritis due to N. meningitidis is rare and bone infections have been reported exceptionally. We report the case of a 1-year old girl who presented with a painful, swollen right knee, accompanied by fever and agitation. Arthrocentesis of the right knee, while patient was under anesthesia, yielded grossly purulent fluid, so we made arthrotomy and drainage. The culture from synovial fluid revealed N. meningitidis, sensitive to Ceftriaxone. The patient received intravenous antibiotherapy with Ceftriaxone. The status of the patient improved after surgical drainage and intravenous antibiotic therapy. She recovered completely after 1 month.Conclusion: This observation illustrates an unusual presentation of invasive meningococcal infection and the early identification of the bacteria, combined with the correct treatment, prevent the complications and even death.

From their discovery, antibiotics have significantly improved clinical treatments of infections, thus leading to diminishing morbidity and mortality in critical care patients, as well as surgical, transplant and other types of medical procedures. In contemporary medicine, a significant debate regarding the development of multi-drug resistance involves all types of pathogens, especially in acute care hospitals due to suboptimal or inappropriate therapy. The possibility of nanotechnology using nanoparticles as matrices to encapsulate a lot of active molecules should increase drug efficacy, limit adverse effects and be an alternative helping to combat antibiotic resistance. The major aim of this study was to obtain and to analyze physico-chemical features of chitosan used as a drug-delivery system in order to stop the antibiotic resistance of different pathogens. It is well known that World Health Organization stated that multidrug resistance is one of the most important health threats worldwide. In last few years, nano-medicine emerged as an improved therapy to combat antibiotic-resistant infections agents. This work relies on enhancement of the antimicrobial efficiency of ceftriaxone against gram(+) and gram(−) bacteria by antibiotic encapsulation into chitosan nanoparticles. Physicochemical features of ceftriaxone-loaded polymer nanoparticles were investigated by particle size distribution and zeta potential, Fourier-transform infrared spectroscopy (FTIR), Thermal Gravimetric Analysis (TG/TGA), Scanning Electron Microscopy (SEM) characteristics techniques. The obtained results revealed an average particle size of 250 nm and a zeta potential value of 38.5 mV. The release profile indicates an incipient drug deliverance of almost 15%, after 2 h of approximately 83%, followed by a slowed drug release up to 24 h. Characteristics peaks of chitosan were confirmed by FTIR spectra indicating a similar structure in the case of ceftriaxone-loaded chitosan nanoparticles. A good encapsulation of the antibiotic into chitosan nanoparticles was also provided by thermo-gravimetric analysis. Morphological characteristics shown by SEM micrographs exhibit spherical nanoparticles of 30–250 nm in size with agglomerated architectures. Chitosan, a natural polymer which is used to load different drugs, provides sustained and prolonged release of antibiotics at a specific target by possessing antimicrobial activity against gram(+) and gram(−) bacteria. In this research, ceftriaxone-loaded chitosan nanoparticles were investigated as a carrier in antibiotic delivery.

The increasing phenomenon of cyberbullying among adolescents needs parental, educational, and social intervention. The study aimed to identify the prevalence of cyberbullying among Romanian adolescents and the importance of gender, family-related factors, self-esteem, and parental styles in both victims and perpetrators. A total of 835 adolescents aged 10–19 years were included in the research. An online questionnaire was specially constructed for this research, gathering socio-demographic and family-related data along with information about cyberbullying as a victim, aggressor, or bystander, and strategies used in order to deal with it. Four psychological scales were used to evaluate self-esteem, loneliness, cybervictimization/cyberaggression, and parental style. (3) Results showed that the most common age for a personal smartphone is M = 10.24 ± 2.43. The main reasons why students use these networks are primarily chatting and fun and less for academic tasks. During the week, adolescents spend 5.53 ± 2.75 h on social media, while during weekends, the duration of smartphone usage almost doubles. Girls are the most common victims of cyberbullying, and less than three-quarters of students believe that aggressors can be both girls and boys, and only a quarter of them have reported an incident. Family affluence, the relationship with parents and classmates, the presence of loneliness and sociodemographic factors were found to be in a strong relationship with the presence of aggression and/or victimization among adolescents. Cyberaggression was found to be positively correlated with the aggressive parental style and negatively correlated with the compassionate and avoidant parental styles. Results are crucial for identifying cyberbullying actors and preventing the negative effects of cyberbullying on psychological, social, and academic life for students, parents, and teachers.

The individual's reaction to imminent death depends on his concept of the existential meaning of death.There are two main, but opposing, concepts, one positive and the other tragic. The first sees death as a transition to another mode of being. Within that three main modalities are to be distinguished, in which is considered either as an element in the cosmic harmony, the reintegration of the individual into the universal (the `Tagorian' mode); or secondly the possibility of man's external existence through his transfer, together with his entire physical and psychological apparatus, to a realm of legend (the `Mioritic' mode); or thirdly the culmination of life, the moment of maximum existential concentration overflowing into the universe and encircling it (the `Rilkian' mode).The second concept, the tragic concept, sees death either as a desired solution, which puts an end to the nothingness of life (the `Tracklian' mode); or as a nonsense, as an absurd injustice of nature (the `common' mode); or as a necessity of which we do not know the meaning, a dialectical moment of eternal change (the `Stoic' mode).The psychological care of the dying involves identification with the patient's concept of death, in order to maintain his morale and possibly diminish his terror of death. The doctor must therefore be a good psychologist and a genuine philosopher, in the strictest sense of the word.

In this paper the authors discuss the continuing dilemma for doctors who have to tell a patient that he has cancer, particularly the moment when he should confirm a diagnosis that most patients have already sensed. For the writers it is most important that the doctor should be a bridge for the patient to return to his everyday world from the physical and spiritual isolation which his disease has created.
