RESUMEN

Traditional network analysis frequently relied on manual examination or predefined patterns for the detection of system intrusions. As soon as there was increase in the evolution of the internet and the sophistication of cyber threats, the ability for the identification of attacks promptly became more challenging. Network traffic classification is a multi-faceted process that involves preparation of datasets by handling missing and redundant values. Machine learning (ML) models have been employed to classify network traffic effectively. In this article, we introduce a hybrid Deep learning (DL) model which is designed for enhancing the accuracy of network traffic classification (NTC) within the domain of cyber-physical systems (CPS). Our novel model capitalizes on the synergies among CPS, network traffic classification (NTC), and DL techniques. The model is implemented and evaluated in Python, focusing on its performance in CPS-driven network security. We assessed the model's effectiveness using key metrics such as accuracy, precision, recall, and F1-score, highlighting its robustness in CPS-driven security. By integrating sophisticated hybrid DL algorithms, this research contributes to the resilience of network traffic classification in the dynamic CPS environment.

RESUMEN

INTRODUCTION: Postoperative infectious complications are commonly encountered in open reduction and internal fixation (ORIF) of maxillofacial fractures. An early diagnosis of infectious processes is the key in preventing morbidity/mortality which could be in the form of loss of hardware and sepsis. To prevent these, various markers of inflammation have been studied in different disciplines of surgery but are found scarce in maxillofacial practice. MATERIAL AND METHOD: The present study was designed to evaluate the perioperative variations in the levels of inflammatory markers. We analysed temperature, TLC, DLC, ALT, AST and CRP in 50 patients of ORIF. Their values were recorded preoperatively as well as at 24 h, 48 h, third day and seventh day postoperatively. The correlation of inflammatory markers with the type of anaesthesia and length of surgery were also analysed. RESULTS: The ranges of various markers in the perioperative phase were: temperature (97.6 ºF-99.2 ºF), TLC (5100/mm3-18200/mm3), neutrophils (51-91%), AST (12-86 IU/L), ALT (12-96 IU/L) and CRP (1.2-150 mg/L). Mean values of all the inflammatory markers achieved their peak values within 24 h postoperatively. These values showed a decline thereafter, with the day 3 and day 7 values being even lower than their preoperative values. This fall in the values was highly significant (p < 0.001) except ALT where the fall was significant (p < 0.05). The data obtained could be used as a reference range by the surgeons for monitoring the recovery of the patient. It could also help in timely interception and expeditious management of an infectious episode in the postoperative phase.

RESUMEN

INTRODUCTION: Animal bites are a significant public health problem, with the majority of bites coming from dogs, cats and humans. These may present as punctures, abrasions, tears, or avulsions. The force and relative bluntness of the teeth also increases the possibility of a crush injury with devitalized tissue .The clinical presentation and appropriate treatment of infected bite wounds vary according to the animal and causative organisms. These wounds have always been considered complex injuries contaminated with a unique polymicrobial inoculum. MATERIALS: This article reviews animal bite wound incidence, bacteriology, risk factors for complications, evaluation components, recommended treatment and prevention based on advanced PUBMED search of the English language literature from the years 1970 to present. CONCLUSION: As the bite wounds are frequently located on the face, an oral and maxillofacial surgeon needs to be familiar with the treatment of animal bites, pitfalls in management and to educate patients on ways to avoid future bite injuries. The management of animal bites is an evidence poor area and most recommendations are based on small case series, microbiological data and expert opinion. The main controversies include whether wounds should or should not undergo primary closure and the use of prophylactic antimicrobials.

RESUMEN

Life-threatening infections of odontogenic or upper airway origin may extend to potential spaces formed by fascial planes of the lower head and upper cervical area. Complications include airway obstruction, mediastinitis, necrotizing fascitis, cavernous sinus thrombosis, sepsis, thoracic empyema, Lemierre's syndrome, cerebral abscess, orbital abscess, and osteomyelitis. The incidence of these "space infections" has been greatly reduced by modern antibiotic therapy. However, serious morbidity and even fatalities continue to occur. This study reviews complications of odontogenic infections. The search done was based on PubMed and Google Scholar, and an extensive published work search was undertaken. Advanced MEDLINE search was performed using the terms "odontogenic infections," "complications," and "risk factors."

RESUMEN

The combination of amoxicillin/clavulanate and metronidazole is a widely-accepted empirical regimen for infections of the odontogenic spaces. Once adequate drainage has been established micro-organisms are less likely to grow and multiply, particularly anaerobes. This may obviate the need for anaerobic coverage after drainage in healthy hosts. We studied 60 patients in this randomised prospective study, the objective of which was to evaluate metronidazole as part of an empirical antibiotic regimen after drainage of infections of the odontogenic spaces. Samples of pus were sent for culture and testing for sensitivity. Amoxicillin/clavulanate and metronidazole were given to all patients. After incision and drainage the patients were randomly allocated to two groups. In the first group both antibiotics were continued, and in the second metronidazole was withdrawn. The groups were compared both clinically and microbiologically. There were no significant differences between the groups in the resolution of infection. Thirteen patients (n=6 in the 2-antimicrobial group, and n=7 in the amoxicillin/clavulanate group) showed no improvement during the 48 h postoperatively. Overall there was need to substitute another antibiotic for amoxicillin/clavulanate in only 6 cases. Six patients in the amoxicillin/clavulanate group required the addition of metronidazole after drainage. We conclude that in healthy subjects metronidazole is not necessary in the period after drainage, but its prescription should be based on assessment of clinical and laboratory markers of infection.

RESUMEN

Numerous explanations have been proposed for the increase in fungal infections including the use of broad-spectrum antibiotics, antineoplastic agents and prosthetic devices. Also increase in proportion of immunocompromised population predisposed to fungal infection might be a contributory factor. Candida albicans is a part of normal flora of the oral cavity. However, it is rarely implicated in maxillary osteomyelitis. Diagnosis of Candida infection is challenging as most symptoms are non-specific and cultures may only become positive late in the course of the infection. Due to scarcity of literature, there are no robust guidelines regarding the most appropriate therapeutic regimens to be employed in such cases. A case of candidal osteomyelitis of mid face is reported suggesting the need for more multicentric long-term studies to formulate and establish appropriate treatment regimens.

RESUMEN

AIMS: The present study was undertaken to evaluate the efficacy of biodegradable plating system for fixation of maxillofacial fractures and to study the morbidity associated with the use of biodegradable plates and screws. MATERIALS AND METHODS: This prospective study consisted of 10 patients with maxillofacial fractures requiring open reduction and internal fixation. Fractures with infection, comminuted and pathological fractures were excluded. All were plated with biodegradable system (Inion CPS) using standard plating principles and observed for a total period of 24 weeks. Characteristics of the fractures, ease of use of bioresorbable plate/screw system and post operative complications were assessed. RESULTS: Of total 10 patients, eight patients were of midface fracture and two pediatric patients with mandibular fracture, with nine male and one female. The mean age was 32.8 years. Out of 20 plates and 68 screws applied to the 10 fractures sites; there were three incidences of screw breakage with no other intraoperative difficulties. Paresthesia of the infraorbital nerve was present in two patients, and recovered completely in four weeks after surgery. Fracture reduction was considered to be satisfactory in all cases. One patient developed postsurgical infection and was managed with oral antibiotics and analgesics. CONCLUSIONS: Favorable healing can be observed through the use of biodegradable plates and screws to stabilize selected midface fractures in patients of all ages, as well as mandible fractures in early childhood, however further studies with more sample size are required.
