Seroprevalence of Herpes Simplex Virus Types 1 and 2 among Pregnant Women in South-Western Romania.

BACKGROUND: Pregnancy-related infections with the human herpes simplex virus (HSV) strains HSV-1 and HSV-2 are particularly noteworthy. There are numerous reported examples of intrapartum transmission of herpes infection, notwithstanding the extreme rarity of intrauterine transfer from mother to fetus. The purpose of this study was to evaluate the seroprevalence of HSV-1 and HSV-2 antibodies in pregnant women in the western region of Romania. METHODS: Pregnant women who presented for routine pregnancy monitoring at Romania's County Clinical Emergency Hospital in Craiova between 2013 and 2016 and 2019 and 2022 were included in the study. In order to find anti-HSV-1/2 IgG antibodies, we conducted serological testing on the patients and gathered demographic information from them. RESULTS: HSV-1 seroprevalence was shown to have declined in rural areas and increased in urban areas, with values between 2013 and 2016 being 89.30% and those between 2019 and 2022 being 84.96%, respectively. Women over 35 who were pregnant had the highest seroprevalence. The seroprevalence of HSV-2 decreased from 16.16% in 2013-2016 to 12.43% in 2019-2022, and both rural and urban areas continued to experience this declining trend. Similarly, pregnant women over 35 years old had the highest frequency of HSV-1 infections. CONCLUSIONS: Establishing educational programs and other actions to reduce the transmission rate and ultimately the prevalence of the disease can be made easier with knowledge about the seroprevalence of HSV-1 and HSV-2 infections.

Prevalence of Multidrug-Resistant Pathogens Causing Bloodstream Infections in an Intensive Care Unit.

Introduction: Bloodstream infections are the most severe infections that cause the highest mortality rate, especially in patients admitted to the intensive care unit (ICU). In this study, we aimed to analyze the distribution, resistance patterns and prevalence of MDR (multidrug-resistant) pathogens isolated in blood samples collected from patients with severe invasive infections hospitalized in the ICU. Methods: A retrospective study of bacterial pathogens was performed on 490 patients admitted to the ICU between 2017 and 2020. The resistance patterns were analyzed using Vitek 2 Compact system. Results: In total, 617 bacterial isolates were obtained. Four hundred and twenty-seven isolates (69.21%) were Gram positive and 190 isolates (30.79%) were Gram negative bacteria. The most frequently isolated micro-organisms identified in the blood samples for the entire period (2017-2020) were Coagulase-negative staphylococci (CoNS) (318-51.54%), followed by Klebsiella pneumoniae (70-11.34%), Methicillin-Resistant Staphylococcus aureus (MRSA) (58-9.40%), Acinetobacter baumannii (45-7.29%) and Enterococcus faecalis (42-6.80%). The number of Klebsiella pneumoniae strains significantly increased in 2020, compared to the previous year (p < 0.05). The Acinetobacter baumannii prevalence was significantly higher in the age group of 20-64 years (10.89%) and over 65 years (3.53%) (p < 0.001). The difference between the prevalence of CoNS in the elderly (67.84%) and in adults (20-64 years) (52.47%) was also statistically significant (p < 0.001). High rates of MDR were found for Acinetobacter baumannii (97.77%), Pseudomonas aeruginosa (65%), Klebsiella pneumoniae (50%), Enterococcus faecalis (47.61%) and MRSA (46.55%). More than 60% of the Klebsiella pneumoniae strains were found to be resistant to carbapenems. Conclusion: The study revealed an alarming prevalence of MDR strains isolated in blood samples of the patients admitted to the ICU, indicating the necessity of consistent application of the measures to control.

A Rare Case of Endophthalmitis with Rhizobium radiobacter, Soon after a Resolved Keratitis: Case Report.

BACKGROUND: Rhizobium (Agrobacterium) species are plant aerobic bacteria, which in some cases can produce endophthalmitis in humans after corneal trauma. CASE PRESENTATION: A 42-year-old female patient presented in the Emergency Department of the Emergency County Hospital of Craiova, Romania, reporting pain, epiphora, and blurry vision in her right eye for about five days. This initial infectious keratitis episode was successfully resolved, but after 20 days she presented again after trauma with a leaf with corneal abscess. In the conjunctival secretion, R. radiobacter was identified. Despite antibiotherapy, the patient's state did not improve, and ultimately the eye was eviscerated. METHODS: A search was performed in the ProQuest, PubMed, and ScienceDirect databases for the terms Agrobacterium, Rhizobium, radiobacter, and eye. We eliminated non-human studies, editorials and commentaries, and non-relevant content, and excluded the duplicates. RESULTS: In total, 138 studies were initially obtained, and then we selected 26 studies for retrieval. After the selection process, we ended up including 17 studies in our analysis. Most studies reported R. radiobacter endophthalmitis after ocular surgical procedures or outdoor activities that involve exposure to soil. CONCLUSION: R. radiobacter is a rare cause of endophthalmitis after eye trauma that generally responds well to usual antibiotherapy, but occasionally can evolve to severe, leading to the loss of the eye.

TEM,CTX-M,SHV Genes in ESBL-Producing Escherichia coli and Klebsiella pneumoniae Isolated from Clinical Samples in a County Clinical Emergency Hospital Romania-Predominance of CTX-M-15.

BACKGROUND: CTX-M betalactamases have shown a rapid spread in the recent years among Enterobacteriaceae and have become the most prevalent Extended Spectrum Beta-Lactamases (ESBLs) in many parts of the world. The introduction and dissemination of antibiotic-resistant genes limits options for treatment, increases mortality and morbidity in patients, and leads to longer hospitalization and expensive costs. We aimed to identify the beta-lactamases circulating encoded by the genes blaCTX-M-15, blaSHV-1 and blaTEM-1 in Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) strains. Furthermore, we established the associated resistance phenotypes among patients hospitalized in the Intensive Care Unit (ICU) from County Clinical Emergency Hospital of Craiova, Romania. METHODS: A total of 46 non-duplicated bacterial strains (14 strains of E. coli and 32 strains of K. pneumoniae), which were resistant to ceftazidime (CAZ) and cefotaxime (CTX) by Kirby-Bauer disk diffusion method, were identified using the automated VITEK2 system. Detection of ESBL-encoding genes and other resistance genes was carried out by PCR. RESULTS: E. coli strains were resistant to 3rd generation cephalosporins and moderately resistant to quinolones, whereas K. pneumoniae strains were resistant to penicillins, cephalosporins, and sulfamides, and moderately resistant to quinolones and carbapenems. Most E. coli strains harbored blaCTX-M-15 gene (13/14 strains), a single strain had the blaSHV-1 gene, but 11 strains harbored blaTEM-1 gene. The mcr-1 gene was not detected. We detected tet(A) gene in six strains and tet(B) in one strain. In K. pneumoniae strains we detected blaCTX-M-15 in 23 strains, blaSHV-1 in all strains and blaTEM-1 in 14 strains. The colistin resistance gene mcr-1 was not detected. The tetracycline gene tet(A) was detected in 11 strains, but the gene tet(B) was not detected in any strains. CONCLUSIONS: The development in antibiotic resistance highlights the importance of establishing policies to reduce antibiotic use and improving the national resistance surveillance system in order to create local antibiotic therapy guidelines.

Locally advanced choroidal melanoma with favorable molecular prognosis - case report.

Uveal malignant melanoma is a rare malignant tumor comprising less than 5% of melanoma cases. It is nevertheless the intraocular tumor with the highest incidence in adults, that arises from the melanocytes in the uveal tract. The authors present the case of a patient with locally advanced choroidal melanoma: from presentation to diagnosis, treatment, and prognosis. A 63-year-old female patient presented in the Ambulatory of the Emergency County Hospital, Craiova, Romania, on the February 1, 2021, accusing visual acuity drop and photophobia in her left eye for about three weeks. Pathology examination in Hematoxylin-Eosin (HE) staining reveals a dense cell proliferation, with small and medium spindle cells and pigment production. The following immunohistochemical markers were used in our study: human melanoma black 45 (HMB45), Ki67, cyclin D1, B-cell lymphoma 2 (Bcl2), S100, Wilms' tumor 1 (WT1), p16, and p53. Uveal melanoma is a malignant tumor that can arise in all the uveal components: iris, ciliary body, and choroid. Out of the three components, iris melanomas have the best prognosis, while ciliary body melanomas have the worst prognosis. It is mandatory for the patient to respect the follow-up schedule, as follow-ups can provide early diagnosis of eventual metastasis.

Behavior pattern of early-stage ocular surface squamous cell carcinoma in non-HIV patients.

Ocular surface squamous neoplasia (OSSN) is a malignant or dysplastic lesion that has its origins in the epithelial cells at the ocular surface. The structures from which these lesions can arise are the conjunctiva, the limbus, and the cornea. Our study was conducted on a group of seven patients with ocular surface squamous cell carcinoma (SCC). Histopathologically diagnosed SCCs were then assessed as well, moderately and poorly differentiated, depending on which area of differentiation dominated in Hematoxylin-Eosin staining. For the immunohistochemical analysis, the following antibodies (markers) were used: Ki67, p53 and B-cell lymphoma 2 (Bcl-2), E-cadherin, and vascular endothelial growth factor (VEGF). Our study group was composed of seven cases of SCCs of the ocular surface. Three were below in T1 American Joint Committee on Cancer (AJCC) stage, two cases were in T2 AJCC stage, and two cases were in T3 AJCC stage. None of our cases were T4, N1 or M1 AJCC tumors. Four of the cases were histopathologically moderately differentiated SCCs of the ocular surface and three were poorly differentiated SCCs. None of the seven patients present human immunodeficiency virus (HIV) infection. P53 immunostaining was strongly present in our study. Bcl-2 overexpression is not a fact that our study highlights. The expression of Ki67 proliferation marker was low in our study. Our study on ocular surface SCC reveals negative assessment of VEGF immunostaining. E-cadherin expression in our study was positive. Ocular surface SCCs are slow growing tumors, with very low metastasis potential, when HIV-infection is not present.

Choroidal melanoma, unfavorable prognostic factors. Case report and review of literature.

Uveal melanoma is the most common intraocular tumor characterized by increased metastatic potential. The tumor develops from uveal melanocytes that, from an embryological point of view, derive from the cells of the anterior neural crest. The risk factors associated with melanoma development are close related to patient phenotype: light-colored hair and iris, fair skin. Recent studies have shown the link between choroidal melanoma and choroidal pigmentation of white-haired and light-colored eyes individuals. Increased pigmentation of the choroid is associated to marked increase in melanocyte density, which from a histological point of view can be a starting point for choroidal carcinogenesis. This case report is about a 36-year-old patient who presented in an outpatient ophthalmological examination for intermittent vision blurring. The ophthalmological examination revealed a view of 0.8 and nasally from the optic nerve head, a prominent tumor-shaped formation was detected during the fundus examination. The presence of a choroidal melanoma was suspected and eye ultrasound, angio-fluorography, optical coherence tomography (OCT) were performed and confirmed the diagnosis. Due to the small size, a team of three ophthalmologists decided to make brachytherapy. The procedure consisting of brachytherapy was temporarily applied to the scleral wall and was done at Debrecen University Hospital, Hungary, the follow-up monitoring being done at the Clinic in Oradea, Romania. Although the initial prognosis was optimistic, after four years of brachytherapy the tumor recurred, the dimensions found were over 14 mm, which is why enucleation was decided. Prior to enucleation, no computed tomography (CT) metastases were detected. Five months after enucleation, hepatic metastases occurred and after another two months, death occurred.

Antimicrobial resistance in bacterial pathogens among hospitalised patients with severe invasive infections.

The most severe infections are invasive infections, due to the fact that the germs can accumulate in multiple sites and produce a body-wide infection known as sepsis. Septic shock has the highest mortality rate among non-traumatic medical conditions. In this study, we aimed to evaluate the incidence and prevalence of invasive infections in a hospital environment. Another second objective was to establish the aetiology of invasive infections in our hospital and the antibiotic resistance profile of the germs involved, which are both important for determining the therapeutic approach for the treatment of these infections. The study included 505 hospitalized patients from which we collected a total of 974 blood cultures. For the analysis of the blood cultures, we used an automated incubator. The bottles flagged as positive were subcultured on blood agar, and the grown colonies were identified using an identification system. Invasive infections had a prevalence rate of 27.72% in our hospital. From the 974 blood cultures, we isolated 170 bacterial strains: Staphylococcus aureus (SA; 63 strains, 37.06%), Klebsiella spp. (27 strains, 15.88%), coagulase-negative staphylococci (CoNS; 18 strains, 10.59%), Enterococcus spp. (17 strains, 10.00%), Escherichia coli (12 strains, 7.06%), Streptococcus spp. (11 strains, 6.47%) and other bacterial species. The prevalence of methicillin-resistant SA (MRSA) in our study was 36.51% from the SA strains. The MRSA prevalence differed significantly according to age (37.50% in adults vs. 28.57% in children, P=0.047) and ICU admission (42.42% in ICU patients vs. 30.00% in non-ICU patients, P=0.018). We performed a multivariate analysis of the invasive infection risk which detected as significant predictors the admission into the cardiology ward and plastic surgery ward. On the whole, the findings of this study indicate that the high prevalence of Gram-positive cocci in blood cultures, mostly SA, with multidrug resistance has important consequences for the management of invasive infections.

Caruncular late-onset junctional nevus: apropos of an anatomo-clinical observation.

Conjunctival nevi are benign tumors, most often located at the nasal or temporal limbus, and rarely in the fornix or tarsus. The vast majority of caruncular tumors are benign and only few are malignant. Most of the caruncular tumors (either benign or malignant) are nevi. We report a case of a 75-year-old female patient presenting caruncular atypical late-onset junctional nevus that clinically arose malignancy suspicion. Ophthalmologic macroscopic examination and slit lamp examination of the right eye were performed. Further blood tests were performed. Carunclectomy was performed two days after admission to hospital. Microscopy revealed the junctional localization, diffuse proliferation of the nevocytes. Immunoreactions with S100 and human melanoma black 45 (HMB45) antibodies were performed. Differential diagnosis of these lesions represents a great challenge. The greatest challenge represents the differential diagnosis between a benign tumor and a malignant life-threatening one, the malignant melanoma, especially with unusual presentation. The presence of a late-onset caruncular tumor with uncertain evolution requires excision biopsy to determine the diagnosis and to establish the best management.

Assessment of VEGF and EGFR in the study of angiogenesis of eyelid carcinomas.

A tumor represents an abnormal tissue growth that can arise from any ocular structure, such as eyelids, muscles or the optic nerve. At the eyelids, there are two main tumor types: basal cell carcinoma and squamous cell carcinoma. Angiogenesis plays a crucial role in growth, invasion and metastasis processes of any tumor. It is well known the fact that without new vessels formation tumors cannot exceed 1-2 mm diameter. Immunohistochemical analysis has been performed on 43 cases of primary carcinomas of the eyelid, diagnosed between 2010 and 2014 in the Laboratory of Pathological Anatomy of the University Emergency County Hospital of Craiova, Romania. Biological material was represented by surgical resection samples, coming from the Clinic of Ophthalmology the anteriorly named Hospital. Within the immunohistochemical study, we have evaluated epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) expression in a group of 43 cutaneous carcinomas of the eyelid, depending on the type and differentiation grade of the tumor. Of the 43 samples, 23 came from patients with eyelid basal cell carcinoma and 20 came from patients with eyelid squamous cell carcinoma. In our study, EGFR and VEGF immunoexpression was superior for squamous cell carcinomas, compared to basal cell carcinomas, fact that was statistically significant. Regarding squamous cell carcinomas, the immunoexpression of these two markers was superior in moderate÷poor differentiated forms, compared to well differentiated forms, fact that was statistically significant. The markers used in this study were found to be associated with the acquisition of aggression and angiogenic phenotypes by analyzed carcinomas.

Histological and immunohistochemical study of the eyelid basal cell carcinomas.

The eyelids represent a frequent site for numerous malignant tumors, which generally present subtle symptoms or can imitate benignant tumors. Our study was carried on 80 patients, 48 males and 32 females aged between 48 and 92 years. The patients were hospitalized in the Ophthalmology Clinic of the Emergency County Hospital of Craiova, Romania. The study was conducted over five years, between 2010 and 2014. Our study included 80 basal cell carcinomas of the eyelids, of which 48 (60%) were nodular basal cell carcinomas, 15 (18.75%) were adenoid basal cell carcinomas, 10 (12.5%) were cystic and seven (8.75%) were morpheaform basal cell carcinoma. Our study showed a moderate expression of bcl-2 marker in the nodular type of basal cell carcinoma and a high expression in the other histopathological types, thus inducing an increased malignancy comparing to the nodular type. E-cadherin was absent in nodular, cystic and adenoid basal cell carcinomas and had a moderate expression in morpheaform basal cell carcinoma. Morpheaform and adenoid types presented 20% expression of Ki67 of the malignant cells nuclei, while the cystic type presented Ki67 expression in less than 10% of the malignant cells nuclei. Due to high morbidity and increasing incidence, basal cell carcinoma of the eyelid represents an important health issue nowadays.

Prevalence and histopathological types of skin carcinomas in Arges County, Romania.

Non-melanoma skin cancers presented a significant incidence increase in the last decades, worldwidely. Even though the impact upon mortality is a relatively low one, through the incidence increase, their impact upon the public healthcare systems is a considerable one. In our study, we evaluated 109 cases of skin carcinomas hospitalized during 2012 in the Department of Plastic Surgery of the Emergency Hospital of Pitesti, Romania, for a surgical treatment. The gender distribution showed slight lesion predominance in women, being recorded 56 (51.38%) tumors in women and 53 (48.62%) in men. The highest incidence of skin carcinomas (75.23%) was recorded in the persons aged over 60-year-old. Of 109 cases of skin carcinomas, 80 (73.4%) carcinomas developed on indignant tegument areas, while 29 (26.6%) on premalignant skin lesions (fiberconjunctive papillomas, keratocantomas, keratosic verrucas). The histopathological study highlighted the fact that of 109 skin carcinomas, 87 (79.82%) were basal cell carcinomas and only 22 (20.18%) were squamous cell carcinomas. The immunohistochemical reaction to 34ßE12 cytokeratin was highly positive in the cells of the basal cell carcinomas and well-differentiated squamous cell carcinomas (except for the "keratosic pearls") and moderately positive in the moderately differentiated squamous cell carcinoma.

Serum and tumor microenvironment IL-8 values in different stages of colorectal cancer.

INTRODUCTION: Colorectal cancer represents a major cause of mortality and morbidity and occupies the third place as cancer incidence and the fourth place as cancer mortality. Colorectal cancer causes 608 000 deaths per year, despite correct applied treatment (surgery and chemotherapy). Interleukin 8 (IL-8) is an important proinflammatory cytokine with an important role in leukocyte chemoattraction. IL-8 also represents an important tumorigenic and proangiogenic factor. MATERIALS AND METHODS: We have studied 68 patients aged between 55 and 70 years, hospitalized in the IInd Surgery Clinic of the Emergency County Hospital of Craiova, Romania. According to TNM grading, the patients were in stages II, III and IV. From these patients, we have prelevated two types of samples: serum and tumor fragment. RESULTS: IL-8 values were significantly increased, both in serum and tumor supernatant. The highest IL-8 values were found in tumor supernatant and in advanced stages; IL-8 increased values were correlated with tumor growth and TNM stage. CONCLUSIONS: IL-8 has an important role in colorectal cancer growth and metastasis and represents an important therapeutic target in this type of cancer. IL-8 represents also a predictor for colorectal cancer prognosis.

Ocular cells and light: harmony or conflict?

Vision is based on the sensitivity of the eye to visible rays of the solar spectrum, which allows the recording and transfer of visual information by photoelectric reaction. Any electromagnetic radiation, if sufficiently intense, may cause damages in living tissues. In a changing environment, the aim of this paper is to point out the impact of light radiation on ocular cells, with its phototoxicity potential on eye tissues. In fact, faced with light and oxygen, the eye behaves like an ephemeral aggregate of unstable molecules, like a temporary crystallization threatened with entropia.

Proatherogenic adipocytokines levels in metabolic syndrome.

INTRODUCTION: Metabolic syndrome was defined by IDF (International Federation for Diabetes, 2007) by abdominal obesity plus at least two of the following: high triglycerides, low HDL-cholesterol, hypertension, high levels of glucose or type II diabetes diagnosed. Obesity is associated with a high cardiovascular risk, abdominal obesity being the most aggressive form, because it secretes cytokines and hormones in comparison to subcutaneous adipose tissue. Adipocytokines secreted by adipose tissue are mediators of atherosclerosis and endothelial damage. MATERIALS AND METHODS: We studied a total of 80 subjects aged between 40 and 60 years with metabolic syndrome, in which the following adipocytokines values were determined: hs-CRP (turbidimetric method), IL-6, TNF-alpha, leptin (ELISA method), in comparison to a control group. RESULTS: The values of these adipocytokines were significantly higher in the studied group compared with the control group and correlated with increased levels of glucose (patients with type II diabetes or increased tolerance test) and with hyper-triglyceridemia. CONCLUSIONS: Patients with metabolic syndrome had increased levels of proatherogenic adipocytokines, particularly leptin, leptin-resistance representing the pathogenic link of obesity. The identification as early as possible of the metabolic syndrome patients allows effective monitoring and correction of cardiovascular risk factors, with the opportunity to reduce morbidity and mortality in young ages. In men, proatherogenic cytokines values presented higher values than in women, which prove the role of abdominal obesity in proatherogenic cytokines production. Although women have a higher percentage of adipose tissue, this is not primarily abdominal adipose tissue.

Oral mucosa self-graft in a patient with invasive conjunctival melanoma: a case report.

Conjunctival melanoma is a rare tumor, while malignant melanoma of the uveal tract is the most common primary intraocular tumor in adults. The authors highlighted the case of a 68-year-old male patient presented in June 2011 in the Ophthalmology Clinic of the Emergency County Hospital of Craiova, Romania, accusing foreign body sensation and the appearance of a tumor in the lower fornix of his right eye. The patient was clinically and paraclinically investigated, and clinically diagnosed with de novo malignant melanoma. The tumor was surgically excised and the lower fornix reconstructed with oral mucosa self-graft. Histopathological diagnosis was de novo, invasive, ulcerated malignant melanoma of the conjunctiva. Ki-67 immunohistochemical staining was also performed. After surgery, the patient was sent to the Oncology Department for specific treatment. Despite the histological poor prognosis factors present in our patient, two years after surgery and chemotherapy, the patient had no clinical sign of local or distance recurrent disease. Continuous ophthalmologic and oncological surveillance is necessary.
