    Background: Myasthenia gravis is an autoimmune neuromuscular disorder that causes the destruction and overall decrease in functional acetylcholine receptors at the neuromuscular junction. The resultant respiratory and cardiovascular implications are a primary cause of mortality; therefore, a complete and comprehensive understandings of this disorder is vital for the anesthesia provider. Anesthesia management in myasthenia gravis is a great challenge for all anesthesiologists. In this disease, even small doses of muscle relaxants could lead to delayed recovery for respiratory muscles. Case report: We present the case of a 38 years old woman (weight 87 kg) diagnosed with Myasthenia Gravis, which symptoms has worsened recently. The case demonstrates the anesthetic challenges involved, with a focus on the overall approach, pharmacologic considerations, physiological changes, and an emphasis on preoperative operative and post-operative optimization. Conclusion: Thymectomy is a common procedure performed in cases of myasthenia gravis (MG) with a thymoma or general MG that does not improve with medical therapy. During anesthesia the use of propofol or sevoflurane with opioids without the use of any neuromuscular blocking agents has been used with success.

    The aim of the study was to investigate the influential factors for hidden blood loss after a total knee arthroplasty and their relationship with the total blood loss. Total knee arthroplasty (TKA) is a crucial treatment of late-stage knee osteoarthritis. Measured blood loss is significantly inconsistent with the hemoglobin (HB) drop postoperatively. Fifty-four patients, 20 males and 34 females, were retrospectively analyzed. The preoperative blood loss and therefore the hidden blood loss following TKA were calculated by the Gross formula. The typical perioperative blood loss was found to be 780±220 ml and therefore the average hidden blood loss was 280±180 ml. No significant differences were found in hidden blood loss for males compared to females. Hidden blood loss may not be reduced by hemostasis during operation with a deflated tourniquet.

    Influenza viruses know no boundaries, representing an example of rapid virus evolution combined with pressure exerted by the host's immune system. Seasonal influenza causes 4-50 million symptomatic cases in the EU/EEA each year, with a global death toll reaching 650,000 deaths. That being the case, in 2014 North Macedonia introduced the sentinel surveillance in addition to the existing influenza surveillance in order to obtain more precise data on the burden of disease, circulating viruses and to implement timely preventive measures. The aims of this study were to give a comprehensive virological and epidemiological overview of four influenza seasons (2016-2020), assess the frequency and distribution of influenza circulating in North Macedonia and to carry out molecular and phylogenetic analyses of the hemagglutinin (HA) and neuraminidase (NA) genes of influenza A(H1N1)pdm09, A(H3N2) from ILI and SARI patients. Our results showed that out of 1,632 tested samples, 46.4% were influenza positive, with influenza A(H1N1)pdm09 accounting for the majority of cases (44%), followed by influenza B (32%) and A(H3N2) (17%). By comparing the sentinel surveillance system to the routine surveillance system, we showed that the newly applied system works efficiently and gives great results in the selection of cases. Statistically significant differences (p = < 0.0000001) were observed when comparing the number of reported ILI cases among patients aged 0-4, 5-14, 15-29, and 30-64 years to the reference age group. The phylogenetic analysis of the HA sequences unveiled the resemblance of mutations circulating seasonally worldwide, with a vast majority of circulating viruses belonging to subclade 6B.1A. The PROVEAN analysis showed that the D187A substitution in the receptor binding site (RBS) of the A(H1N1)pdm09 HA has a deleterious effect on the its function. The A(H3N2) viruses fell into the 3C.2a and 3C.3a throughout the analyzed seasons. Molecular characterization revealed that various substitutions in the A(H3N2) viruses gradually replaced the parental variant in subsequent seasons before becoming the dominant variant. With the introduction of sentinel surveillance, accompanied by the advances made in whole-genome sequencing and vaccine therapeutics, public health officials can now modify their approach in disease management and intervene effectively and in a timely manner to prevent major morbidity and mortality from influenza.

    (Spontaneus)  Rectus sheath hematoma ((S)RSH) is an accumulation of blood in the sheath of the rectus abdominis muscle, secondary to rupture of an epigastric vessel or muscle tear. It is defined as spontaneous in patients without history of abdominal trauma. It can be located supra- or infraumbilically. Although the exact incidence is unknown, Klingler et al. observed 23 cases (1.8%) of rectus sheath hematoma among 1257 patients evaluated by ultrasound for acute abdominal disorders.  Ultrasonography can help in the diagnosis, but CT scan is most accurate in its ability to define the lesion. When diagnosed clinically, a conservative therapeutic program can usually be instituted. Only in cases of supportive management failure, progressive and large hematoma or uncontrollable hemodynamic patients, interventional management including surgery or less invasive newer techniques is indicated. Case presentation: We present two cases of SRSH in patients using oral anticoagulant agent (acenocoumarol). Their chief complaint was sudden onset of acute abdominal pain. On admission they were haemodynamically stable. After thorough clinical evaluation a suspicion for SRSH diagnosis was made and then confirmed by ultrasonography and CT. Both of them were successfully treated conservatively and discharged home in a good general condition. Conclusion: These two cases illustrate the accurate diagnosis of SRSH treated conservatively leading to optimal patient outcomes.

    The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a persistent negative impact on both the public health and the global economy. To comprehend the origin, transmission routes and discover the mutations that alter the virus’s transmissibility and pathogenicity, full-length SARS-CoV-2 genomes have to be molecularly characterized. Focusing on a two-year time frame (2020-2021), we provide an in-depth virologic and epidemiological overview of the SARS-CoV-2 pandemic in the Republic of North Macedonia by assessing the frequency and distribution of the circulating SARS-CoV-2 variants. Using genetic characterization and phylogenetic analysis we shed light on the molecular evolution of the virus as well as test for a possible connection between specific SARS-CoV-2 haplotypes and the severity of the clinical symptoms. Our results show that one fifth (21.51%) of the tested respiratory samples for SARS-CoV-2 were positive. A noticeable trend in the incidence and severity of the COVID-19 infections was observed in the 60+ age group between males and females. Of the total number of positive cases, the highest incidence of SARS-CoV-2 was noticed in 60+ males (4,170.4/100,000), with a statistically significant (0,0001) difference between the two sexes. Additionally, a 1.8x increase in male mortality and consequentially significantly higher number of death cases was observed compared to females of the same age group (0.001). A total of 327 samples were sequenced in the period March 2020 - August 2021, showing the temporal distribution of SARS-CoV-2 variants circulating in North Macedonia. The phylogenetic analysis showed that most of the viral genomes were closely related and clustered in four distinctive lineages, B.1, B.1.1.7, B.1.351 and B.1.617.2. A statistically significant difference was observed in the 2C_1 haplotype (p=0.0013), where 10.5% of the patients were hospitalized due to severe clinical condition. By employing genetic sequencing, coupled with epidemiological investigations, we investigated viral distribution patterns, identified emerging variants and detected vaccine breakthrough infections. The present work is the first molecular study giving a comprehensive overview of the genetic landscape of circulating SARS-CoV-2 viruses in North Macedonia in a period of two years.

    The development of aloarthroplasty of the hip is continuously rising. After implantation of a total cement-free hip endoprosthesis, often there is a periprosthetic femoral bone loss. Alendronate has been shown to be a potent inhibitor of bone resorption activity; it inhibits osteoclastic bone resorption, increases bone mass, and plays a significant role in post-implantation stabilization of the femur. The aim of this study was to determine the effect of alendronate on osteointegration of hip endoprosthesis.Material and methods: The study analyzed 10 patients operated on with implantation of a total cement-free hip endoprosthesis (THP). The included patients were examined by a radiographic method at 6 and 12 months and DXA method at 6 and 12 months. Results: The study showed differences in the values of bone mineral density and bone mineral content in the interval between 6 and 12 months in patients undergoing THP, and hence we can conclude that alendronate therapy after THP implantation reduced periprosthetic loss of bone mass and implant stiffening. Alendronate is a proven inhibitor of periprosthetic bone loss that occurs after prirmary impantation of a total cement-free hip endoprosthesis.

    Loss of periprosthetic bone tissue in primary hip endoprostheses is common in clinical practice. This loss can be progressive and in extreme conditions can jeopardize the longevity of the prosthesis. In order to monitor the function of Alendronate therapy for bone maintenance, the study included 50 patients with implanted total cement-free hip endoprosthesis (TPH). The first group of 25 patients received Alendronate, calcium and vitamin D3 orally postoperatively. The second group of 25 patients were examined postoperatively without therapy. Patients were followed by radiographic and dual-energy X-ray absorptiometry (DXA) at 6 and 12 months. The study showed that in patients with TPH there was a difference in the X-ray findings as well as occurrence of osteolysis in certain Gruen zones, which was confirmed by changes in the state of bone mineral density (BMD) and bone mineral content (BMC) in the interval between 6 and 12 months using the DXA method. Alendronate therapy after TPH implantation allows reduction of periprosthetic bone mass loss, maintenance of bone mineralization and implant hardening.
