One of the types of external resorption is external cervical resorption, which usually manifests itself in the cervical aspect of the teeth. Clinically, external root resorption is usually asymptomatic. When external cervical resorption occurs, cervical cavitation, gingival contour irregularity, or pink discoloration of the overlying enamel can often be observed. This case report describes the clinical and radiologic diagnosis (cone beam computed tomography) and treatment of external cervical resorption according to the current guidelines of the European Society of Endodontology. After 4 years, the tooth remained functional and the esthetic effect was satisfactory.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9492024-04-25T00:00:00.000+00:00Self-image of people with mandibular prognathism before and after orthognathic surgeryhttps://sciendo.com/article/10.21164/pomjlifesci.907<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction</bold>: Mandibular prognathism, also called progenia, is a type of anterior malocclusion that has negative effects on physical and mental health.</p> <p>The aim of the study was to determine differences in the selfimage of people with mandibular prognathism before and after orthognathic surgery.</p> <p><bold>Materials and methods</bold>: The study included 155 people – 79 of whom had a mandibular prognathism (group A) and 76 of whom had a previous mandibular prognathism that had already been corrected by surgery (group B). The research method used was a diagnostic survey that included original questions about wellbeing, self-esteem, and self-confidence.</p> <p><bold>Results</bold>: Group A statistically significantly more often experienced feelings of frustration, lower self-confidence, embarrassment, concern about appearance, especially when meeting new people, and lack of comfort due to their appearance being the center of attention than group B. People in group A were statistically significantly more likely to avoid smiling or laughing in company, to hide a smile in pictures, to avoid looking at themselves in the mirror, to compare their appearance to others, and to avoid meetings due to dissatisfaction with their appearance than were people in group B. People in group A were statistically significantly less likely to preferably rate the general appearance of the face, the profile of the face, the appearance of the face from the front, and the appearance of the teeth than were people in group B. People in group A were statistically significantly less likely to preferably rate the general appearance of the face, the profile of the face, the appearance of the face from the front, and the appearance of the teeth than were people in group B.</p> <p><bold>Conclusions</bold>: Orthognathic surgery is a very important factor affecting the psyche of people with prognathism. People with mandibular prognathism before orthognathic surgery experience more negative feelings about their appearance, more often engage in behaviors aimed at concealing a malocclusion, and rate their appearance worse than people who have undergone orthognathic surgery. In view of this, comprehensive medical care, including psychological care, should be provided before, during, and after surgery.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9072024-04-25T00:00:00.000+00:00A misdiagnosed case of cancer leading to delayed HIV diagnosis and B-cell lymphoma: a lesson on the importance of timely HIV testinghttps://sciendo.com/article/10.21164/pomjlifesci.969<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction</bold>: This case report describes a serious complication of delayed human immunodeficiency virus (HIV) diagnosis in a patient initially misdiagnosed with palliative-stage cancer and subsequently diagnosed with B-cell lymphoma. This situation highlights the diagnostic challenges and treatment implications following HIV diagnosis, and underscores the critical importance of accurate and timely HIV detection in oncology patients.</p> <p><bold>Case presentation</bold>: A 39-year-old man was initially diagnosed with lung cancer based on computed tomography and histopathologic findings. He was treated with 2 lines of chemotherapy over an 8-month period, the neoplastic lung lesions progressed, and he was referred to palliative care. Two years after his initial diagnosis, during the management of an actively bleeding gastric tumor, he was diagnosed with HIV and referred to an infectious disease unit. Immediate antiretroviral treatment was initiated after diagnosis, and further evaluation confirmed the presence of B-cell lymphoma. A retrospective review suggested that the initial cancer diagnosis was likely misinterpreted and was in fact lymphoma, a malignancy commonly associated with HIV. Lymphoma treatment was initiated, and after 1 year, the patient achieved HIV-1 virologic suppression and near-complete remission of all lesions.</p> <p><bold>Conclusions</bold>: This case highlights the consequences of delayed HIV diagnosis, which can significantly alter treatment course and patient prognosis. The initial misdiagnosis of cancer and subsequent ineffective treatment highlights the importance of HIV testing, particularly in patients presenting with malignancy. It also highlights the role of multidisciplinary collaboration, the need for prompt initiation of antiretroviral therapy, and the efficacy of targeted anticancer therapies for HIV-associated malignancies.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9692024-04-25T00:00:00.000+00:00Fetal sex identification in early pregnancyhttps://sciendo.com/article/10.21164/pomjlifesci.944<abstract> <title style='display:none'>Abstract</title> <p>The need to determine the sex of the fetus in early pregnancy is usually based on medical indications for early implementation of appropriate therapeutic procedures, and is sometimes driven by parental curiosity. Medicine has made tremendous progress in early diagnosis of fetal sex in the last decades. The diagnostic methods described in the literature are characterized by varying degrees of accuracy, cost, and potential risk to the fetus. For these reasons, there is an ongoing debate about when and in which cases a particular method should be used. This paper presents an overview of the current methods of fetal sex determination.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9442024-04-25T00:00:00.000+00:00The importance of parental attitudes for locus of control among adolescentshttps://sciendo.com/article/10.21164/pomjlifesci.958<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction</bold>: The process of personality formation is closely related to the period of adolescence. One of the dimensions of personality – locus of control (LOC) can be defined as a person’s beliefs about the locus of reinforcement control. Considering that the locus of control is formed as a result of social learning, the adolescent’s perception of the relationship between his own behavior and its consequences may depend largely on his parents’ attitudes toward him.</p> <p>The aim of this study is to examine the relationship between parental attitudes and adolescents’ locus of control.</p> <p><bold>Materials and methods</bold>: The study was conducted among 386 students aged 13–16 years (M = 14.87): 208 girls and 178 boys were included. The research instruments used in the study were the Parental Attitude Scale (SPR-2) by M. Plopa and the Sense of Control Questionnaire – revised version (KBPK-R) by Krasowicz-Kupis and Wojnarska.</p> <p><bold>Results</bold>: According to the results of the study, parental attitudes are related to both the general level of locus of control in adolescents and the locus of control in a situation of success and failure.</p> <p><bold>Conclusions</bold>: The results of the study underscore the importance of parental attitudes and the role of parents in shaping adolescent personality. Research suggests that parental attitudes may be both a risk factor and a protective factor in the development of adolescent psychopathology.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9582024-04-25T00:00:00.000+00:00Antioxidant potential of extracts from different parts of L.https://sciendo.com/article/10.21164/pomjlifesci.1042<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction</bold>: Free radicals are formed mainly as a result of environmental pollution, ultraviolet (UV) radiation, and stress. These factors contribute to the formation of oxidative stress, which is involved in the aging process of the skin, among other things. Antioxidants are compounds found naturally in plant products that have beneficial effects on human health. Natural antioxidants found in fruits, vegetables, and other plants have a positive antiaging effect. Therefore, in recent years there has been an increased interest in plant raw materials to obtain antioxidants useful not only in cosmetology. One of these plants that is commonly grown in our country is chicory (<italic>Cichorium intybus</italic> L.). The aim of the study was to evaluate the antioxidant properties of alcoholic extracts obtained from 3 parts of <italic>C. intybus</italic> L. The influence of extraction time and solvent selection on the antioxidant activity of various parts of chicory was also investigated.</p> <p><bold>Materials and methods</bold>: The research material consisted of dried herb, stem, and root of <italic>Cichorium intybus</italic> L. Low molecular weight alcohols, i.e. methanol, ethanol, isopropanol, and n-propanol at concentrations of 40%(v/v), 70%(v/v) and undiluted were used to obtain extracts using ultrasonic-assisted extraction. The antioxidant properties of the extracts were evaluated by 2,2-diphenyl- 1-picrylhydrazyl (DPPH) and 2,2’-azinobis[3-ethyl-2,3-dihydrobenzothiazole- 6-sulfonate] diammonium salt (ABTS) methods.</p> <p><bold>Results</bold>: Extracts from all parts of chicory showed antioxidant potential, but it varied depending on the part of chicory to be used. The highest activity was observed for herb extracts and the lowest for root extracts. Methanol seemed to be the best solvent for extraction to obtain the extracts characterized by high antioxidant capacity.</p> <p><bold>Conclusions</bold>: Based on the obtained results, it can be concluded that due to their antioxidant activity, <italic>C. intybus</italic> L. extracts, especially those obtained from the herb, can be suggested as components of natural cosmetics.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.10422024-04-25T00:00:00.000+00:00Traveller treated with renal replacement therapyhttps://sciendo.com/article/10.21164/pomjlifesci.972<abstract> <title style='display:none'>Abstract</title> <p>In developed countries, renal replacement therapy (RRT) is available to any patient who needs it. Renal replacement therapy patients still believe that starting therapy means being tied to their home nephrology center, which prevents them from traveling. The role of specialists is to inform their patients that they can travel. Guidelines concerning the ways in which patients should be prepared for trips are available, but they are mainly based on expert opinion. Therefore, there is a need for extensive research to evaluate the safety of long-distance travel in the discussed patient population.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9722024-04-25T00:00:00.000+00:00Analysis of the management of preterm rupture of membranes after the 37 week of gestationhttps://sciendo.com/article/10.21164/pomjlifesci.959<abstract> <title style='display:none'>Abstract</title> <p>Premature rupture of membranes or synonymously prelabor rupture of membranes (PROM) is defined as the outflow of amniotic fluid before the onset of uterine contractions. When it occurs after 37 weeks of gestation, it is called term PROM or tPROM, and its prevalence is as high as 8–10% of pregnancies. tPROM is a significant risk factor for intrauterine infection, which threatens both the pregnant woman and the fetus.

In hand surgery, most of the operations can be performed under regional (brachial plexus block) or local (infiltration) anesthesia. These procedures can be carried out by the surgeons themselves, which allows them to operate without the assistance of an anesthesiologist. The objective of this study was an analysis of the efficacy and safety of anesthesia to operations in hand surgery performed by surgeons, without the assistance of anesthesiologists.</p> <p><bold>Materials and Methods</bold>: This analysis was based on records of anesthesia protocols completed by the surgeons who performed the procedure and who operated on the patients. The following variables were considered: efficacy of anesthesia, adverse effects associated with anesthesia and complications.</p> <p><bold>Results</bold>: Over a 10-year period (2013–2022), a total of 16,583 procedures were performed, of which 5638 (34%) were carried out under anesthesia by surgeons, without the assistance of anesthesiologists. The efficacy of these procedures (local and brachial plexus blocks) was 98%. A total of 203 (3.6%) anesthesia-related events were noted, most of which were transient, requiring emergency intervention and without serious consequences. In only 12 cases (0.02%) adverse effects led to cancellation and postponement of the planned operation.</p> <p><bold>Conclusion</bold>: Anesthesia for operations in hand surgery performed by surgeons themselves and without the assistance of anesthesiologists is effective and safe and is associated with numerous benefits for patients, surgeons, and the budget of the medical care system.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9502024-04-25T00:00:00.000+00:00Necrosis of both hands and feet in the course of streptococcal sepsis: a case reporthttps://sciendo.com/article/10.21164/pomjlifesci.934<abstract> <title style='display:none'>Abstract</title> <p>A case of severe streptococcal phlegmon of the right upper extremity with subsequent necrosis of both hands and feet in a young, homeless alcoholic man is reported.

Due to limited availability and increasing resistance to antibacterial drugs, they should be used with caution, especially in patients with limited treatment options. It should be noted that both diazobicycloctane and boron inhibitors are inactive against metallo-β-lactamase (MBL) producing strains. The aim of this study was to evaluate the in vitro susceptibility of carbapenemase-producing Gram-negative bacilli to meropenem/vaborbactam, imipenem/relebactam and ceftazidime/avibactam in clinical samples from hospitalized patients.</p> <p><bold>Materials and methods</bold>: The analysis included 102 clinical strains of carbapenemase-producing Enterobacterales and nonfermenters from hospital centers in Łódź, Poland. A minimum inhibitory concentration test strip method was used to determine antimicrobial susceptibility.</p> <p><bold>Results</bold>: Seventy-one percent of <italic>Escherichia coli</italic>, 40% of <italic>Klebsiella pneumoniae</italic>, and 67% of <italic>Pseudomonas aeruginosa</italic> were resistant to meropenem/vaborbactam, 57%, 66%, and 60% to imipenem/relebactam, and 71%, 74%, and 60% to ceftazidime/avibactam, respectively. Considering carbapenemase resistance mechanisms, the highest efficacy was observed in <italic>Klebsiella pneumoniae</italic> carbapenemases (KPC) strains for each drug combination tested.</p> <p><bold>Conclusions</bold>: The results of our study confirm the conclusions of the studies evaluating the susceptibility of Gram-negative, fermenting, and non-fermenting bacilli to ceftazidime/avibactam, meropenem/vaborbactam and imipenem/relebactam and indicate that there are reasonable grounds for using these antibiotics in the treatment of patients hospitalized with serious infections.

Vascular endothelial growth factor-A and SDF-1α levels were determined by enzyme-linked immunosorbent assays (ELISAs). Endothelial progenitor cells were evaluated by flow cytometry.</p> <p><bold>Results</bold>: The study showed significantly higher levels of both VEGF-A and SDF-1α in ET patients compared to controls (Me = 65.22 pg/mL vs Me = 25.34 pg/mL; Me = 2351.17 pg/mL vs Me = 1742.50 pg/mL, respectively). However, we could not demonstrate a different count of EPCs in ET patients compared to healthy controls. Furthermore, in 40 ET patients with JAK2 V617F mutation (65%), only VEGF-A levels were significantly higher compared to JAK2 V617F negative patients (Me = 72.00 pg/mL vs Me = 53.38 pg/mL). SDF-1α levels were significantly elevated in patients over 60 years of age (Me = 2635.00 pg/mL vs Me = 2395.02 pg/mL). We found positive correlations between VEGFA and SDF-1α and between VEGF-A and EPCs.</p> <p><bold>Conclusions</bold>: Clinical features such as age over 60 years and Janus 2 kinase (JAK2) mutation may increase angiogenesis in patients with essential thrombocythemia. Despite a positive correlation between VEGF-A and EPCs, the present study suggests weak cooperation between proangiogenic factors and vasculogenesis.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9682024-04-25T00:00:00.000+00:00Tumour of the vermiform appendix strangulated in the femoral hernia: a case reporthttps://sciendo.com/article/10.21164/pomjlifesci.856<abstract> <title style='display:none'>Abstract</title> <p>Strangulation of the vermiform appendix into the femoral hernia sac (de Garengeot hernia) is very rare.

The patient presented to the hospital with a 3-day-long history of a palpable lump in the right groin. She had no other significant complaints, but USG imaging showed suspicion of the strangulated femoral hernia containing a bowel. The patient was operated on. As the tumour was not suitable to remove via groin incision, laparotomy was performed, followed by a release of the appendix with the tumour and their resection together with a fragment of the caecum. The postoperative course was uneventful, and histological examination showed appendiceal mucinous neoplasm with high-grade dysplasia.

Treatment options include arthrocentesis and intra-articular drug administration. Adverse events associated with such interventions are rarely described in separate articles and may be overlooked when presented in clinical trial reports. Their identification in the medical literature is difficult due to the need to develop a rich set of keywords. This systematic search and review aims to identify and map adverse events associated with injections into the TMJ. Primary clinical trials of TMJ disorders treated with joint irrigation and/or drug administration were included. Data were extracted using a predesigned form and presented in text, tables, and graphs. A total of 58 adverse events were identified, more than half of which were pain and/or swelling. Overall, 14 types of events were classified into 3 categories (distant, local, and articular), none of which were fatal or life-threatening. These were, in order of most frequently diagnosed: pain and/or swelling (52%), ear pressure (5%), eyelid paresthesia (5%), periarticular tissue atrophy (5%), generalized rash (4%), hypoesthesia (4%), open bite (4%), skin hypopigmentation (4%), headache (3%), local rash (3%), malocclusion (3%), mandibular hypomobility (3%), TMJ noises (3%), and fever (2%).</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.10002023-12-26T00:00:00.000+00:00Gallstone ileus – case description and literature reviewhttps://sciendo.com/article/10.21164/pomjlifesci.926<abstract> <title style='display:none'>Abstract</title> <p>Gallstone ileus is a rare disease, arising due to intestinal obstruction caused by cholelith.

After the 2-step polishing procedure, the samples were divided into 2 groups: control group (K) and thermal cycling group (TC). Samples from the TC were subjected to thermal cycling according to ISO 11405 (THE-1100, SD Mechatronik GmbH). Surface geometry was evaluated by profilometry (Turbowave v. 7.36, Hommel-Etamic) and scanning electron microscope – SEM (VEGA 3, Tescan Analytics).</p> <p><bold>Results</bold>: The applied thermal cycles increased the surface roughness of conventional RBCs: TEC (p = 0.000007), GD (p = 0.04), and CX (p = 0.0005). A reduction in the surface roughness of bulk-fill composites was observed in the case of materials: XF (p = 0.000003) and QF (p = 0.0002). Thermal cycling was shown to alter the surface roughness of the TEC, CX, XF, and QF materials.</p> <p><bold>Conclusion</bold>: The application of thermal cycling in a water environment in accordance with the ISO 11405 standard causes the degradation of the organic matrix and the exposure of filler molecules on the surface of both conventional and high-viscosity bulk-fill composites. Some of the tested RBCs, especially those containing modern hydrophobic monomers, are less susceptible to these processes.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9452023-12-26T00:00:00.000+00:00Treatment of dens invaginatus: 4-year follow-uphttps://sciendo.com/article/10.21164/pomjlifesci.979<abstract> <title style='display:none'>Abstract</title> <p>Dens invaginatus is a rare developmental defect that can complicate the proper diagnosis and treatment of teeth.

The aim of this study was to re-evaluate the advantages and disadvantages of TUMT.</p> <p><bold>Materials and methods</bold>: The non-randomized study included 4590 patients with BPH. All patients were on pharmacological treatment. Prior to the study, patients underwent digital rectal examination (DRE), ultrasound examination, uro-dynamic examination, and prostatic specific antigen (PSA) concentration. Exclusion criteria included suspected prostate cancer on DRE, an ambiguous result of the urodynamic examination, suggesting a neurological component in lower urinary tract symptoms (LUTS), and elevated PSA concentration. In the end, 3329 patients were enrolled for further analysis. Of this group 2159 patients elected to receive TUMT. The others decided to continue their pharmacotherapy. Two questionnaires were used to evaluate the effect of TUMT on the relief of urinary symptoms and erectile dysfunction (ED). The International Prostate Symptom Score (IPSS) was used for LUTS and the International Index of Erectile Function-5 (IIEF-5) for ED.</p> <p><bold>Results</bold>: After 6 months from thermotherapy, more than 50% of patients experienced an improvement in their urination (p &lt; 0.0018), while in the pharmacological group only 30% did (p &lt; 0.031). Approximately 28% of all patients regained erection. Before thermotherapy, only 12% reported no erection problems. In contrast, a further deterioration of erectile function (EF) was observed in the reference group (differences with TUMT at p &lt; 0.0001). Apart from transient fever or temporary urinary retention, no serious complications were observed.</p> <p><bold>Conclusions</bold>: It appears that TUMT is still a valuable option for BPH, especially in outpatient practice and for those patients who wish to protect their EF.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9992023-12-26T00:00:00.000+00:00Changes in the lifestyle among dialysis patients – a descriptive studyhttps://sciendo.com/article/10.21164/pomjlifesci.966<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction</bold>: End-stage renal disease (ESRD) requires dialysis treatment. This treatment changes patients’ lives, including limitations on physical activity.</p> <p>In this study, we highlighted the mobility aspects of patients’ lives compared to the control group (non-dialyzed).</p> <p><bold>Materials and methods</bold>: Seventy-nine dialysis patients and 125 controls were studied. The study used an original questionnaire on socioeconomic status, physical activity, and lifestyle. All data were statistically analyzed between dialysis patients and controls divided into female and male groups.</p> <p><bold>Results</bold>: Most of the dialysis patients were obese, and each had concomitant chronic diseases of other organs. Significantly lower levels of employment (p = 0.001 for women; p = 0.005 for men) and physical activity (p = 0.047 for women; p = 0.001 for men) were observed in dialysis patients compared with controls. Both groups had high motivation and knowledge about the health benefits of physical activity. However, dialysis patients had significantly more concerns about engaging in physical activity (p &lt; 0.001).</p> <p><bold>Conclusions</bold>: Dialysis patients are at risk for the negative consequences of occupational and physical inactivity. Healthcare professionals (physicians and physiotherapists) can take advantage of the high motivation of dialysis patients to overcome the fear of physical activity. Based on the current study and a previous study on the posture of dialysis patients, a universal set of exercises for dialysis patients has been created and is available on the YouTube platform: <ext-link ext-link-type="uri" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="https://www.youtube.com/watch?v=Ng0sVOViQ-0&amp;feature=youtu.be">https://www.youtube.com/watch?v=Ng0sVOViQ-0&amp;feature=youtu.be</ext-link>. The exercises can be done during dialysis and at home.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.21164/pomjlifesci.9662023-12-26T00:00:00.000+00:00en-us-1
