Endogenous Endophthalmitis in COVID-19 Patients

Intrinsic endophthalmitis is indeed behavior that causes eye disease that spreads into the bloodstream from a distant primary site. The intraocular disease caused by hematogenous microbial proliferation is known as indigenous endophthalmitis. Extrinsic and intrinsic endophthalmitis are the two types of endophthalmitis that exist. The presence of an external point of entry is linked to extrinsic endophthalmitis. Intrinsic endophthalmitis is a kind of septicemia caused by a blood-borne infection. Endophthalmitis is a disease of all the inner coating of the eyeball except the sclera and cornea, which is accompanied by substantial, increasing vitreous swelling. Endophthalmitis is a severe ocular crisis with severe visual and general consequences. An exterior injury of the entrance, such as injury, operation, or an inflamed cornea, is the most prevalent route of entry for potential pathogens. Endophthalmitis has a complex etiology, with many pathogenic species and substantial regional heterogeneity. The treatment of endophthalmitis has evolved dramatically during the last century. Endophthalmitis induced by direct inoculation dissemination of pathogenic microbes is a rare occurrence that occurs most commonly in sick or disadvantaged people. Intravenous medication usage, diabetes mellitus, immunological impairment, cancer, prolonged hospitalization, or systemic antibiotic therapy have all been linked to a 0.04 percent incidence rate. Haden described metastatic endophthalmitis in a seriously sick patient with pneumococcal cerebrospinal encephalopathy treated with intravenously anti-meningococcal serum in the 1918 volume of the Journal Ophthalmology. Endogenous endophthalmitis, unlike extrinsic endophthalmitis, needs comprehensive systemic antibiotic treatment. In indigenous endophthalmitis, the illness originates not in the eye but elsewhere in the body. As a result, it is necessary to obtain comprehensive cultures. Patients are sometimes unable to carry out their functions in society or household. As a rest, the person cannot cope financially and socially in his environment. Many social and influential factors are disturbed, and the patients are often depressed. Cosmetically the surgeries are not satisfying. Artificial prosthetics can be used, but they're seldom of minimum functional importance. Such interventions can be helpful for the patient. The focus should be made to deliberately save the patients and not just the cosmetic value of the surgery. Persons with chronic endophthalmitis had more excellent eyesight than people with symptomatic or subacute endophthalmitis. Improvements in eyesight were observed in individuals with persistent or subacute keratitis several months after the surgery more frequently than in people with symptomatic endophthalmitis. Nevertheless, in 40 percent of the overall all instances with an abrupt start, there have been no improvements or even decrease in visual acuity.

Comparison of the Postoperative Effects of Local Antibiotic versus Systemic Antibiotic with the Use of Platelet-Rich Fibrin on Impacted Mandibular Third Molar Surgery: A Randomized Split-Mouth Study

The surgery of the impacted mandibular third molar is the most frequent procedure in dentistry. The prescription of systemic antibiotics after the third molar extraction is widespread among dentists, but this is still argumentative. This study is aimed at evaluating the postoperative effects of local antibiotic mixed with platelet-rich fibrin (PRF) and a postoperative systemic antibiotic prescribed for mandibular third molar surgery. The study included 75 patients divided into a control and 4 test groups ( n = 15 ). In the control group, only PRF was placed into the extracted socket, and no antibiotic was prescribed. In the first and third groups, PRF was applied to the socket; penicillin and clindamycin were prescribed as oral medications, respectively. In the second and fourth groups, only PRF combined with penicillin and clindamycin was applied into the socket, respectively. The outcome variables were pain, swelling, analgesic intake, and trismus. These variables were also assessed based on the first, second, third, and seventh days following the operation. Unpaired Student’s t -test and Mann–Whitney U test were used for analysis. There were significant differences in the total VAS pain scores between the control and group 3 ( p < 0.05 ), groups 1 and 2 ( p < 0.01 ), and group 4 ( p < 0.001 ) in ascending order. For analgesic intake, there was no significant difference for group 1 ( p > 0.05 ). However, there were statistical differences between the control group and groups 2 and 3 ( p < 0.01 ) and group 4 ( p < 0.001 ). Trismus and swelling did not differ among the groups ( p > 0.05 ). This study showed that the effects of local and systemic antibiotics with the use of PRF reduced postoperative outcomes. Moreover, local antibiotics with PRF may be a viable method to avoid the possible side effects of systemic antibiotics.

Systemic antibiotic therapy of patients with acute bacterial sinusitis taking into account resistance

Acute rhinosinusitis is one of the most common diseases in the world. According to statistics, about 10 million cases are registered in Russia every year.Acute bacterial rhinosinusitis (ABRS) in most cases develops as a result of an acute respiratory viral disease, proceeds easily and it does not require antibiotic therapy. However, it significantly reduces the patient's quality of life in cases of moderate and severe disease, and in the absence of timely treatment, can lead to intracranial complications (meningitis, encephalitis, intracranial abscesses, etc.) and orbital (reactive edema of the eyelid, phlegmon of the orbit, periorbital abscesses, etc.). To avoid complications, with exacerbation of rhinosinusitis, it is necessary to choose the right antibiotic therapy, taking into account the resistance of the microorganisms that caused the disease.The article describes the differential diagnosticprinciples of bacterial rhinosinusitis according to the latest recommendations and research in this area, the most common antibiotic-resistant pathogens in the practice of an ENT doctor are presented, the issue of choosing the correct systemic antibiotic therapy for the treatment of patients with moderate and severe acute bacterial rhinosinusitis is considered according to modern data on the sensitivity of bacterial pathogens to antibacterial drugs prescribed in the otorhinolaryngologist's practice. The article presents data on a new universal cephalosporin of the 3rd generation (the active ingredient is cefditoren), as a second- and third-line drug, due to its high activity against most causative agents of acute bacterial rhinosinusitis, and clinical observation using the above antibacterial agent within the framework of the considered topics.

Topical antibiotics for acute rhinosinusitis in children

The authors presented an overview of the existing data on inhalation therapy with antibacterial drugs in acute rhinosinusitis and exacerbation of chronic rhinosinusitis in children. The overview includes general information about the etiology and features of the course of acute rhinosinusitis. It also contains indications for systemic and topical antibiotic therapy in acute rhinosinusitis specified in the Russian clinical guidelines. The advantages of using a combination preparation of thiampheni-col and N-acetylcysteine by inhalation therapy for acute rhinosinusitis in children and adults are considered separately. A clinical case of a 15-year-old female patient with complaints of persistent rhinitis over the past 4-5 years is discussed. Historical information: a patient had a runny nose over the last 4-5 years: persistent, viscous nasal discharge with moderate nasal congestion. Nasal symptoms worsened with episodes of acute respiratory illness, and nasal discharge became mucopurulent. The child was preliminarily diagnosed with chronic rhinosinusitis (incomplete remission), moderate course. To reduce the severity of the symptoms of the disease, which were present at the time of examination, the following were recommended: daily one-to-two irrigation of the nasal cavity with slightly hypertonic (1.5-3%) solutions of sea water, followed by a toilet of the nasal cavity; in case of episodes of colds with the appearance of mucopurulent secretions, inhalation therapy in a pulsating mode of the inhaler with a solution of thiamphenicol and N-acetylcysteine at a dose of 500 mg once a day (in the first half of the day) for the next 10 days and further; the use of a nasal spray of mometasone furoate, 200 mcg per day during inhalation therapy for another 3 weeks. At the follow-up examination after 10 days of treatment, the patient reported a significant decrease in the severity of nasal symptoms, which coincided with an improvement in the rhinoscopic status. It can be concluded that the use of topical antibacterial drugs by inhalation therapy for acute rhinosinusitis, despite all its advantages, is not an equivalent substitute for systemic antibiotic therapy in the treatment of severe and especially complicated forms of the disease. The inhalation therapy is recommended in the presence of indications for systemic antibiotic therapy, since it is an auxiliary method of treatment, the action of which is aimed at enhancing the effect of systemic antibiotics.

Acute otitis externa in children: causes, diagnosis, treatment, clinical report

Acute otitis externa is a common disease in the pediatric population, characterized by diffuse inflammation of the external auditory canal. Typical symptoms of acute otitis externa include otology, itching, congestion, and a feeling of fullness in the sore ear. In the case of active inflammation, the process can go to the tympanic membrane, and acute otitis media will join the external one. Primary therapy for diffuse uncomplicated acute otitis externa should include a local antimicrobial drug, without systemic antibiotic therapy. Topical therapy with antibacterial drugs in combination with anesthetics is the most rational. A clinical case of a 12-year-old patient with acute diffuse otitis externa and otitis media with effusion; acute nasopharyngitis; and adenoiditis, which was established based on anamnesis and clinical data is presented. Complex therapy was prescribed, which included local antibiotic therapy with a complex topical drug for the treatment of imperforated otitis externa and imperforated otitis media. At reexamination 5 days later, the patient demonstrated positive dynamics, pain in the left ear was eliminated. In cases of uncomplicated diffuse otitis externa, as well as in cases of its combination with otitis media with effusion, topical antibiotic therapy is a major priority. It should be borne in mind that the topical medication is more effective with the cleansing of the external auditory canal from inflammatory secretion. If it is used correctly, it would provide positive dynamics without systemic antibiotic prescription. It preserves the microbiome and mobilizes the body’s defenses. The application of complex topical antibiotic drugs can be widely recommended in pediatric practice.

Efficacy of Nano-Encapsulated Daptomycin in an Experimental Methicillin-Resistant Staphylococcus aureus (MRSA) Bone and Joint Infection Model

S. aureus bone infections remain a therapeutic challenge, leading to long and expensive hospitalizations. Systemic antibiotic treatments are inconsistently effective due to insufficient penetration into the infectious site. In an osteomyelitis model, the single local administration of nanoparticle-encapsulated daptomycin allows sterilization of the infectious sites after 4 and 14 days of treatment, while daily systemic treatment of daptomycin for 4 days was not effective. These results demonstrate the great interest of this local antibiotic treatment.

Bihemispheric Cortical Infarcts in an Adult Secondary to Escherichia coli K1 Meningitis

Cerebral ischemia is a known complication of meningitis. Most <i>Escherichia coli</i> meningitis-induced infarcts have been reported in the neonatal and pediatric population. To the best of our knowledge, there have been no previous reports describing bilateral cortical infarcts in an adult secondary to a K1 strain of <i>E. coli</i> meningitis, and herein we report a case in a 25-year-old female. The challenge in treating this patient was determining the duration of systemic antibiotic treatment and whether or not to use steroids. This study demonstrates the necessity of early diagnosis and treatment of <i>E. coli</i> meningitis to prevent neurological complications, including stroke.

18F-Fluoride PET/CT Imaging of Medication-Related Osteonecrosis of the Jaw in Conservative Treatment—A Case Report

Medication-related osteonecrosis of the jaw (MRONJ) is a serious side effect in antiresorptive treatment. Treatment of MRONJ is considered primarily conservative with oral mouth rinses and antibiotics but may demand surgery, depending on the complaints and general condition of the patient, the extent of the necrosis, and the overall prognosis with respect to the underlying disease. A 77 year old female patient with invasive ductal breast cancer and bone metastases was treated with intravenous bisphosphonate (BP) zoledronic acid. During therapy, she developed MRONJ in the mandible with severe pain. Clinical examination revealed confluent exposed bone of the lower left jaw and a fistula at the right molar region. The panoramic radiograph revealed a mandibular osseous involvement with diffuse radiopaque areas between radiolucent areas. For preoperative planning, 18F-fluoride positron emission tomography/computed tomography (PET/CT) of the jaw was performed, showing substantially increased 18F-fluoride uptake in regions 38 to 47 of the mandible with a focal gap in region 36 (area of clinically exposed bone). CT revealed medullary sclerosis and cortical thickening with confluent periosteal reaction and focal cortical erosion in the regions 37 to 42, whereas the regions 43 to 47 were only subtly sclerotic without cortical thickening. After systemic antibiotic therapy with sultamicillin following significant symptom and pain relief, 18F-fluoride PET/CT imaging was performed again after 5 months. No changes in either CT and PET were observed in regions 38 to 42, whereas the bony sclerosis was slightly increased in regions 43 to 47 with a slight reduction of 18F-fluoride uptake. 18F-fluoride PET/CT showed no significant changes assessing the extent of MRONJ prior and after systemic antibiotic therapy, providing no evidence that conservative treatment reduced the extent of the MRONJ-affected jawbone. The additional information of 18F-fluoride PET enables to identify the true extent of MRONJ which may be underestimated by CT imaging alone. Patients with MRONJ undergoing conservative treatment could benefit because additional imaging may be avoided as the pre-therapeutic 18F-fluoride PET/CT delivers all information needed for further treatment. Our findings support the recommendation of a surgical approach as long-term antibiotics cannot downsize the extent of MRONJ.
