Technique presentation: The combination of Pectoralis and Serratus Plane Nerve Blocks for cardiac implantable devices
DOI: 10.2478/amma-2024-0038
Cardiac resynchronization therapy devices, implantable cardioverter defibrillators, and pacemakers are used to treat advanced systolic heart failure, ventricular tachyarrhythmias, and bradyarrhythmia. Over the past ten years, there has been a notable rise in the number of cardiac implanted electronic device implants because of mounting evidence of better survival and quality of life among specific patient populations. Appropriate analgesia and sedation throughout the implantation procedure is crucial for the patient’s stability. This paper aims to describe the advantages of both interpectoral plane block (PECS I) and interpecto-seratus plane block (PECS II) for the implantation of cardiac devices.
Combining PECS I and PECS II blocks provides advantages for the thoracic wall procedures. While the PECS I block anesthetizes the medial and lateral pectoral nerves, PECS II extends coverage to upper intercostal nerves (T2-T7), as well as the long thoracic and thoracodorsal nerves, covering areas that are not anesthetize adequately by PECS I alone. Minimizing the need for opioids, leading to fewer opioid related side effects contributing to shorter recovery time and nonetheless creating less discomfort for the patient.
This combined regional technique offers comfort to the patient due to its sole puncture needed for performance and by offering an extensive anesthesia at the site of the procedure.

Unveiling rhabdomyosarcoma: A rare cause of ischialgia
DOI: 10.2478/amma-2024-0039
Rhabdomyosarcoma (RMS) represents a rare subset of mesodermal malignancies characterized by skeletal muscle differentiation, exhibiting a notably low incidence among adults and demonstrating inferior prognosis compared to pediatric counterparts. The 5- and 10-year overall survival rates were determined to be 30% and 18%, respectively, with a median age of onset at 46.5 years and median overall survival duration of 2.3 years. Current challenges in RMS research encompass optimizing local control, managing systemic disease, refining risk stratification methods, and elucidating disease progression patterns. While aggressive therapeutic interventions remain imperative, novel and individualized treatment modalities are imperative to enhance long-term outcomes. This research reported an elderly female patient presenting persistent lower back pain, persisting over several months, despite seeking medical consultation from multiple sources. Subsequent diagnostic investigations confirmed the diagnosis of rhabdomyosarcoma, denoting the relatively rare etiology of said initial symptoms. Hence, it is imperative to reconsider many differential diagnoses in the case of ischialgia.

Primary intraosseous mucoepidermoid carcinoma – A case report of two rare occurrences in the maxilla
DOI: 10.2478/amma-2024-0035
Introduction: Primary intraosseous mucoepidermoid carcinoma is a rare malignancy originating from minor or ectopic salivary gland tissue within the jawbones, presenting diagnostic challenges, especially in young patients. This article is aimed at oral and maxillofacial radiologists, surgeons, oncologists, and dental practitioners who encounter such cases, highlighting the importance of early recognition for effective treatment planning.
Case Presentation: Two cases of primary intraosseous mucoepidermoid carcinoma in the maxilla are presented. The first involves a 27-year-old female with pain and swelling in the left upper jaw. Cone-beam computed tomography showed a multicystic hypodense lesion with bicortical expansion and palatal perforation. The second case features a 15-year-old with similar radiographic findings but with additional lymph node involvement, indicating a more aggressive disease. The first case was localized and painful, while the second was painless, with the lesion extending into the maxillary sinus. Diagnoses were confirmed via fine needle aspiration cytology and histopathology, followed by surgical resection.
Conclusion: These cases highlight the need for clinicians to consider primary intraosseous mucoepidermoid carcinoma as a differential diagnosis for jaw swellings across all ages. Advanced imaging, particularly cone-beam computed tomography, is crucial for precise diagnosis and early intervention, leading to improved patient outcomes.

Utilization of lipoxins and other specialised pro-resolving mediators in the prevention and treatment of diabetic nephropathy and diabetic cardiovascular disease
DOI: 10.2478/amma-2024-0037
Diabetes mellitus type 2 is a chronic disease caused by insulin resistance. Whilst first originating in the adipose tissue, this pathophysiological process later affects the muscles and the liver as well. This induces high plasma levels of glucose and fatty acids, leading to the inflammatory-related chronic complications of diabetes, such as diabetic nephropathy and diabetic cardiovascular disease. Specialized pro-resolving mediators are lipid mediators responsible for resolving inflammation and could therefore be beneficial in the management of chronic diabetes complications. The aim of this review is to assess if specialised pro-resolving mediators have the potential to attenuate the chronic complications of diabetes. Specialised pro-resolving mediators, especially lipoxins, can modulate both diabetic nephropathy and diabetic cardiovascular disease. In mice it was demonstrated that, at the glomerular level, lipoxins reduced collagen deposition and expression of pro-inflammatory markers. In human saphenous vein smooth muscle cells instead, lipoxins were able to reduce collagen deposition and vascular smooth muscle cells proliferation and chemotaxis. Aspirin is a medication that could be used to modulate specialised pro-resolving mediator levels, as aspirin triggered-specialised pro-resolving mediators exist. Aspirin triggered-specialised pro-resolving mediators are pro-resolving substances with similar effects, but synthetised in a different way, requiring the partial blockage of the cyclooxygenase 2 enzyme. These results demonstrate how such substances could be useful in the treatment of diabetic patients and why further research is needed to create efficient and economical medications.

Confounding elements in the recognition of severe hyperkalemia. A case report
DOI: 10.2478/amma-2024-0036
Introduction: Severe hyperkalemia is a life-threatening condition that demands a rapid diagnosis and prompt treatment. The following case report highlights the possible complexity in the clinical presentation of this condition and the importance of a thorough assessment of patients that do not provide the classical clinical findings.
Case presentation: A 40-year-old male called the emergency services for low blood pressure and an overall altered state. Upon arrival, the prehospital team found a patient with shock signs that was complaining of feeling unwell and reported profuse diarrhea starting three days prior. Additionally, the patient also had muscle weakness and occasional spastic movements of the limbs and face. During the assessment, the patient went suddenly into cardiac arrest, life support (including the management of hyperkalemia) was immediately started and return of spontaneous circulation was soon obtained. Point-of-care blood testing established the diagnosis of severe hyperkalemia. Definitive in-hospital care consisted mainly of fluid resuscitation, circulatory support, hemodialysis and antimicrobial therapy and the patient was discharged 16 days later with no neurological impairment.
Conclusions: Although atypical, hyperkalemia can be caused by diarrhea in certain circumstances and its clinical manifestations can be misleading. Thus, keeping a broad clinical perspective and early use of blood tests can ensure proper treatment of life-threatening hyperkalemia.

Preliminary study to obtain some fluoroquinolone-tetracycline hybrids
DOI: 10.2478/amma-2024-0034
Objective: This paper aimed to synthesize hybrids of fluoroquinolones with tetracycline class representatives and conduct their preliminary characterization.
Methods: A reaction between tetracycline representatives (doxycycline, tetracycline), formaldehyde (acting as a molecular connector) and fluoroquinolone representatives (ciprofloxacin, moxifloxacin, and norfloxacin) was attempted through a classical reflux synthesis with an electrical heating source (heating mantles) and a microwave-assisted reflux synthesis. One synthesis group also used cupric chloride dihydrate as a catalyst. The samples were analyzed using Differential Scanning Calorimetry, Electrospray Ionization Mass Spectrometry, or High-Performance Liquid Chromatography.
Results: The results indicated the formation of a compound different from the parent components in the case of doxycycline-norfloxacin and possibly tetracycline-norfloxacin hybrids.
Conclusions: Both synthesis methods yielded similar results. The influence of the catalyst did not seem to have been significant. The synthesis method is simple and one-step, using non-toxic solvents. Future studies involving molecular docking and microbiology could be employed to further explore the mechanism of action and the microbiological effects of the hybrids.

DOI: 10.2478/amma-2024-0033
Background: Dental caries and obesity are prevalent chronic conditions across all age groups, with common multifactorial causes such as diet and socioeconomic status.
Objective: The aim of this study was to determine if there is a correlation between the decay missing filled tooth (DMFT) index and body mass index (BMI) in preschool children.
Materials and Methods: The study included 390 children aged 4 to 6 years, comprising 262 boys and 128 girls. The DMFT indices were assessed by two dentists, while anthropometric measurements were conducted by a nutritionist. BMI was calculated using the WHO AnthroPlus application.
Results: Most children were of normal weight (332), with 28 being underweight and 30 overweight. There were no obese children. Underweight children had a mean DMFT index of 3.7 ± 3.56, significantly higher than those of normal weight (2.0 ± 1.88) and overweight children (1.9 ± 1.60).
Conclusions: This study highlighted an association between the DMFT index and BMI in preschool children, with underweight children having a higher DMFT index compared to those of normal weight and overweight.

Food-effect study on the pharmacokinetics of indapamide prolonged-release tablets
DOI: 10.2478/amma-2024-0032
Objective: A comparative study was performed to evaluate the food impact on the pharmacokinetics of indapamide 1.5 mg prolonged release tablets (SR).
Methods: The data evaluated were collected from 2 randomized, single dose, 2-way crossover bioequivalence studies with administration of indapamide to healthy Caucasian volunteers under fasting and fed conditions, respectively. Forty-four eligible subjects aged 19–39 years were enrolled in both studies: 22 subjects received indapamide under fasting (study 1) and the other 22 under fed (study 2) conditions. Blood samples were collected following the same schedule before and up to 96.0 hours after drug administration. Blood concentration of indapamide were quantified by a validated LC-MS/MS method. A non-compartmental analysis was used to calculate the pharmacokinetic parameters. Mathematical deconvolution was applied to assess indapamide absorption. Statistical significance for differences in key pharmacokinetic parameters was evaluated using an ANOVA test, with a significance threshold of p < 0.05.
Results: In total, 44 subjects were included in analysis. The outcomes demonstrated that ingestion of food independently reduced the mean of tmax by 4.64 h and increased the value of Cmax by 19.7 ng/mL, while the AUC remained unchanged.
Conclusions: Notably, differences in drug absorption rate obtained after co-administration of indapamide with food had no significant influence in safety and efficacy of the drug.
