" Background and Aim: Abdominal compartment syndrome is a life-threatening complication that can occur in trauma patients and greatly increase their mortality. Although there is a better scientific understanding of the general phenomena involved in the pathogenesis of this complication, the particular risk factors and their implications in the trauma patient population are yet to be deciphered. Methods: The authors conducted research through 3 electronic databases (PubMed, Scopus, and ScienceDirect) using the following search formula: "(ACS OR abdominal compartment syndrome) AND (*trauma*) AND (risk factor)". Subsequently, additional search formulas were used, including the risk factors taken into consideration (i.e. "shock", "hypotension", "acidosis", "base deficit", "coagulopathy", "retroperitoneal hematoma", "HOB elevation", "fluid resuscitation", "damage control laparotomy"). Results: Throughout the 41 articles analyzed in this paper, 7 risk factors transcended and were further discussed: head of bed elevation/patient positioning, fluid resuscitation, the "lethal triad" of acidosis hypothermia and coagulopathy, Damage Control Laparotomy, shock/hypotension, retroperitoneal hematoma and demographics (age, gender, and race). Conclusions: To summarize, many potential risk factors were evaluated for the envisagement of the present paper, but the ones that prevailed the most were excessive fluid resuscitation, shock/hypotension, retroperitoneal hematomas, and the lethal triad. Consistent with other studies, no connection was found between age, gender, or race and the development of ACS. Further studies should focus more on the likely involvement of damage control laparotomy and patient positioning, as well as hypocalcemia, in the unfolding of ACS in trauma patients"

Single ventricle heart (SVH) is a very rare congenital heart disease. However, since the introduction of Fontan's intervention, the survival rate of patients with SVH has been significantly improved, increasing the number of women who may become pregnant in this condition. It has been already reported, in isolated case presentations or in some series of patients, that the pregnacy in the context of SVH and Fontan circulation carries a very high risk for first trimester miscarriage, maternal cardiovascular or obstetric complications and for an increased rate of pre-term birth. Therefore, it is an open field of debate weather or not to allow pregnancy in this category of patients. We are presenting the case of a 22 years old patient who underwent two surgeries for SVH: a Glenn procedure when she was 2 years old and the implantation of a Fontan circuit at the age of 16 years. Since the last surgery she was under permanent internal cardiac stimulation. During the pregnancy the patient was hemodynamically stable, with a normal resting oxygen saturation and a good ejection fraction of the single ventricle. However, the evolution of this patient has become even more challenging due to an aberrant praevia placental lobe. This condition brought her to hospital for several episodes of metrorrhagia and uterine contractions. She delivered at 33 weeks of gestation by emergency Caesarian section with a good evolution until discharge, for mother and the newborn. This case is supporting the opinion that pregnancy can be tolerated without important cardiovascular events in patients with SVH and Fontan circulation, unless heart failure or cardiac arrythmia are associated. Nevertheless, the obstetrical complications remain an important problem in pregnancy overcome of patients with Fontan circulation for SVH that can be superimposed with other unfavorable conditions, like aberrant praevia placental lobe in this case. During the management of such particular clinical settings difficult decisions must be taken, including those addressing the antithrombotic therapy that will be covered in the presentation of this case.

Atopic dermatitis (AD) is the most common chronic inflammatory skin condition, characterized by multiple recurrent eczematous lesions and intense itchiness. It is a multifactorial skin disorder involving an association between genetic and environmental factors that lead to a defect of the epithelial barrier in conjunction with immunological dysregulation. Over the last decade, there has been an increasing understanding of the role of the human microbiota in preserving skin integrity and that a shift in the homeostasis of these microorganisms may lead to dysbiosis and disease. Diversity in the intestinal microbiome and its role in the etiopathogenesis of AD has been described and has become of great interest. In this report, we have reviewed the importance of the gut microbiome and the possible mechanism in the pathogenesis of AD as well as the therapeutic impact of probiotics and prebiotics

"In the context in which life expectancy increases and the population becomes more active, the number of people who are affected by gonarthrosis symptoms increases proportionally. By the year 2030, in the United States of America, one in three adults is expected to suffer from gonarthrosis, this prediction will be the beginning of an epidemic. Total knee arthroplasty has been shown to relieve pain and improve joint function; however, studies have shown that active young patients still have limitations in performing high-level activities such as dancing, golfing, skiing, and gardening. Currently, modern TKA implants are designed to reproduce the normal biomechanics of the knee joint, mimicking the physiological "medial pivot" pattern with greater compliance on the medial compartment between the tibial insert and femoral condyle and less congruence on the lateral side. "

Background: This topic is aimed to review the treatment approach in adult patients diagnosed with urosespsis, in order to decrease mortality and to maximize the outcome of the antibiotic stewardship efforts. Methods: We present an approach of antibiotic therapy in urosepsis from an infectious diseases physician perspective, based on the recently published data integrating the epidemiology of the urinary tract infections in a multidisciplinary hospital from Romania. Results: The principles of therapy in urosepsis should have five goals, but not limited to rapid diagnosis, specific intensive care unit treatment, obtaining urine and blood cultures, anti-infective treatment and identifying and correction of underlying risk factors. Due to the higher prognostic value, the antimicrobial therapy in urosepsis should consist in "two steps" regimen: initial antimicrobial therapy, based on "empirical" approach for the first 48 - 72 hours and directed or "definitive" antimicrobial therapy adapted to the susceptibility profile of the isolated pathogens, the penetration into the urinary tract and the patient clinical response. Clinicians should be aware of the different antibiotic susceptibility profile of the bacteria from the hospital compared to the community. Thus, the initial choice of antimicrobial agents depends on several criteria like the severity of illness and the risk factors for multidrug resistant pathogens: the immune status of the patient (age, debilitating chronic illnesses, immunosuppressive treatment or uncontrolled malignancies), broad-spectrum antimicrobial use and health care environment exposures in the previous 3 to 6 months, susceptibility of prior urinary isolates, and local community resistance prevalence of bacteria. Conclusions: Our important messages highlighted the need of a holistic approach of urosepsis, in a multidisciplinary team, with integration of risk factors for AMR, focusing on the first phase of antibiotic treatment as the main driven of the survival rate.

In an attempt to standardize the X-ray analysis and to create relevant correlations between it and the functional results, we present a pilot model of an artificial neural network based on a Bayesian belief network (BNN) designed for the automatic analysis of anteroposterior X-ray of the knee following total knee arthroplasty and more precisely the analysis of the tibial component. A prospective analysis was conducted in which 30 patients were analyzed and two groups resulted: the first was made up of 12 cases considered "normal" by the examiners (optimal positioning and cementation) and the second one, which was considered "pathological" (incorrect positioning or cementation) and included 16 cases. Based on 22 points established on the tibial component several geometric sizes (calculated parameters) were computed. Several parameters were compared and the results were up to 75% accuracy, 81.25% sensitivity, and 66.7% specificity. BBNs can be a solution for X-ray evaluation of total knee arthroplasty and can improve the understanding of its evolution. It needs confirmation in time, its accuracy rising with the number of patients introduced in the analysis algorithm.

Clear cell acanthoma represent a benign solitary epidermal tumor of the clear glycogen containing epithelial cells, which is quite common in dermatologic practice. The etiology of this tumor formation is not known exactly at the moment. Clinically, the lesion appears as a single reddish papule or papule-nodule and the characteristic of this lesion is represented by a peripheral scaling collarette. Although solitary lesions represent the most common form of presentation of the acanthoma with clear cells, less than thirtieth cases of multiple clear cell acanthoma, from two up to four hundred lesions, have been described in the medical literature to date. The diagnosis based on clinical features frequently needs to be supported using a dermoscopy exam and, in most cases, a histopathology exam is required. The treatment consists is complete removal (standard surgical excision, cryotherapy, electrofulguration alone, carbon dioxide laser or shave removal or curettage followed by electrofulguration). For the cases with multiple lesions, cryotherapy, or topical 5- fluorouracil are preferred. We present the case of a 62-year-old male patient, presented to our Dermatology Department for multiple asymptomatic rounded papules and multiple exophytic nodular tumor formations (approximate fifteen), on the lower extremities, which had occurred approximately two years previously and gradually increased in number.

Diabetes and increased body mass index are two of the most associated comorbidities in patients undergoing total knee arthroplasty. With the number of patients undergoing knee arthroplasty increasing and with the incidence of diabetes and increased BMI, we can expect that in the coming decades the association of the two comorbidities will be frequent. An ethical issue arises when the patients who are refused for total knee arthroplasty are instructed to change the risk factors, and they fail either because of a mental problem or because of a physical problem. This study analyzes the effects of controlled, uncontrolled, uncomplicated and complicated diabetes on the rates of postknee arthroplasty complications. The study proposes to evaluate obese patients in terms of functional outcomes and postoperative complications after total knee arthroplasty.

NAFLD (Non-alcoholic fatty liver disease) is a condition of high importance due to its increased prevalence, estimated at 24% of the global population, and its potential progression to advanced liver disease, cirrhosis, and hepatocellular carcinoma. One-quarter of NAFLD patients have NASH (non-alcoholic steatohepatitis), which is histologically described as liver steatosis, inflammation, fibrosis, hepatocyte injury, and death. Metabolic disruptions, such as obesity, diabetes, and dyslipidemia, are considered to have a great impact on the development of NASH. Patients may have NAFLD for a long time before progressing into NASH, which highlights the necessity of periodic imaging and biochemical evaluation of the liver, and also presents an optimal window of therapeutic intervention. The challenge in developing treatment for NASH stems from the slow progression of the disease and the reliance on sequential biopsies as the diagnostic and staging tools. Several non-invasive tests have been developed as potential future alternatives to the current invasive gold standard. This review aims to assess the current available methods of diagnosis and treatment targeting inflammation.

Rotational malalignment complication following TKA, is common but can be avoided with proper surgical technique. This paper reviews the literature regarding rotational alignment during TKA, femoral and tibial rotation, and highlights the techniques prior in obtaining proper rotational positioning, nevertheless correct positioning in all three planes is important. Proper femoral component positioning in the axial plane is done using as landmarks the posterior condylar line (PCL), surgical transepicondylar axis (sTEA), anatomical transepicondylar axis and the trochlear anteroposterior (AP) axis. The paper describes the angular relationships between these landmarks and the distal femur. Axial tibial positioning is done when using intraarticular landmarks, the combination of more than one landmark could be a solution for solving this problem. The consensus is that femoral component should be positioned according to TEA but the interobserver variability of this land mark is very high. The rotation of the tibial component remains an open subject, most studies suggesting a point between half of the distance of patellar ligament and 1/3 of the internal tuberosity as optimal landmark.

One of the most controversial topics in total knee arthroplasty is rotation of the femoral component. The current gold-standard in total knee arthroplasty consists in positioning the femoral component in 3 degrees of external rotation to the epicondylar axis, having as reference the tangent to the posterior condyles. Achieving the correct rotation of the femoral components is one of the main goals during total knee arthroplasty. Multiple complications can result from internal femoral rotation, such as lateral patellar tilt, patellar subluxation or dislocation, mobilization with movement on pain, and low survival rates of the femoral components. Postoperative rotational assessment of protective components can only be performed correctly using computed tomography. The known evaluation methods are related to anteversion of the femoral neck, femoral trans-epicondylar line, insertion of the posterior cruciate ligament from the tibia and tibial tuberosity. The purpose of this study was to evaluate the rotation of the prosthetic components in the group of patients with the methods validated by studies and to find alternatives to evaluate the rotation of the femoral component. Thirty-four patients diagnosted with gonarthrosis, proposed for total knee arthroplasty, were included in the study. This is a prospective cohort study in which applied statistics consisted of analyzing data using frequency and percentage for qualitative and mean variables and standard deviation for quantitative variables

"Melanoma outcome seems different between females and males, with a potential protective role of estrogen (E) through estrogen receptors (ER) expression into the tumor. In the study of ERs, both alfa (ERα) and beta (ERβ) is a well-known endocrine elements in non-melanoma tumors, like mammary and endometrial cancer. Immunohistochemistry (IHC) assessment of melanoma concerning ERs represents a path to explore the tumor profile to provide useful information concerning the prognostic and potential adjuvant treatment. Currently, this is not a routine practice, nor a mandatory step for deciding the medical therapy. Typically, IHCs are based on usual kits for mammary tumors regarding ERs configuration. Prior/concomitant use of oral contraceptives and hormonal replacement therapy is not correlated with a better prognostic in melanoma; neither have they represented a contraindication for survivors of melanoma; a subset of tumors might present a higher ER expression which is potentially targeted by the hormone-based treatment as SERMs (Selective Estrogen Receptors Modulator), for instance, tamoxifen. Experimental studies on melanoma cell lines confirmed the anti-tumor activity of ERβ which might function as a prognostic marker. G-protein-coupled estrogen receptors in melanocytes and keratinocytes might be involved, too. Additional crosstalk of TGF-β (Transforming Growth Factor β), respective IGF1 (Insulin-like Growth Factor), and ERα expression are involved in tumorigenic pathways. Recent preclinical studies showed the potential benefits of diarylpropionitrile, a selective agonist of ERβ; pyrazole derivates 21-23 can block ERs. Murine melanoma models showed the interference of anti-estrogenic medication (like molecule fulvestrant) to enhance immune checkpoint blockade, a modern approach to solid cancers. The proliferation of melanoma might be partially explained by ERs; whether this is generally applicable or there is a subgroup of tumors particularly related to E status is still debatable. The subject of E status in melanoma is far from clear at this point and further studies are necessary concerning this particular issue to implement it as a practical approach in the daily management of a disease that still has a very severe prognostic nowadays "

Abstract: Bladder trauma is caused by a direct blow to the distended bladder, severe injury fracturing the pelvis, iatrogenic, or penetrating wounds. Early detection and diagnosis are key to successful management of cases, but omission or late reveal of bladder damage increase mortality and create long-term problems. A bladder injury may not always present with immediate obvious signs and symptoms, especially in a multi-trauma patient, who is also more difficult to investigate. Moreover, during the COVID-19 pandemic, delayed patients' access to tertiary, multidisciplinary hospitals, increases the risk for delayed diagnosis and also increases the need for more specialists from different surgical and non-surgical areas to raise their awareness of less common manifestations of bladder trauma. We present a review of literature and cases of less common bladder damage from the perspective of a multi-disciplinary team in the University Emergency Hospital in Bucharest. Keywords: bladder injury, pelvic fracture, urinary fistula

Colorectal cancer is the third most common cancer worldwide and represents a significant major public health issue.
Therefore, the interest in detecting the multiple factors implied in the development of cancer has increased recently. One of the
factors could be the Helicobacter pylori infection, but a direct causal connection is missing. This gram-negative bacterium infects
approximately 4 billion individuals globally and various conditions such as gastroduodenal ulcers or gastric adenocarcinomas can
be induced by it. Some of the reported carcinogenic effects of Helicobacter pylori bacterium are hypergastrinemia, chronic
inflammation, dysbiosis, and toxin production. Each of these elements involved in the pathogenesis has various mechanisms of
action. Dysbiosis can occur due to various treatments for the eradication of the Helicobacter pylori infection. This bacterium also
has a proinflammatory effect at the gastric level which can predispose to the development of dysplasia or even neoplasia. The
toxins produced by this bacterium, such as the vacuolating cytotoxin A, promote inflammation. In this review, we discuss the
possible connections between the Helicobacter pylori infection, through its diverse pathogenic mechanisms, and colorectal
neoplasm. Prospective studies are necessary to determine whether there certainly is a direct link between the two conditions.

Magnesium alloys represent a new research direction in the field of orthopedic resorbable metal materials, because it has several important properties that recommend it as an excellent resorbable biomaterial for implants. From in vitro studies, Magnesium has osteoconductive properties, promoting the formation of new bone by stimulating the adhesion of osteoblastic cells, this leading to the idea that it will induce formation of hard callous at fracture site. The present study followed the in vivo evaluation of the biodegradation of pins made of Mg-1Ca alloy introduced centromedulary in rabbit tibiae, with previously induced experimental fractures. The influence of the biodegradation process on the formation of the bone callus was evaluated through radiological images and histopathological examinations. At the same time, we evaluated the function of vital organs through histopathological examinations and blood tests. We chose intramedulary nailing (IMN) with pins, because in orthopaedic surgery this is the golden standard for fractures of tibia or femur. In the radiological images obtained, we notice callus formation at the level of the experimental fracture at 6 weeks after surgery. The histological sections made from the samples collected from the fracture zone adjacent to the Mg1Ca alloy implant, confirm the formation of the bony callus. The trichrome Masson sections show a normal bone development with newly formed bone tissue at the tissue - alloy interface. In the sections harvested from the vital organs, no pathological changes are observed. These observations suggest that the biodegradation process of the Mg-1Ca alloy do not interfere negatively with the biological process of bone formation, allowing the formation of the bone callus and do not confirm the suspicion of pathological changes induced by systemically released corrosion products and gas embolism in vital organs.
