Antibiotic therapy in patients with amniotic fluid sludge and risk of preterm birth: a meta-analysis.

PURPOSE: Amniotic Fluid Sludge (AFS) has been theorized to be sonographic evidence of an underlying infection/inflammation and studies have concluded that approximately 10% of the patients who show signs of preterm labor with intact membranes have an underlying intraamniotic infection, mostly subclinical, carrying an increased risk for preterm birth with its subsequent neonatal and maternal complications. The purpose of the present systematic review is to evaluate the impact of antibiotic therapy on preterm birth rates of women diagnosed with AFS. METHODS: We searched Medline, Scopus, the Cochrane Central Register of Controlled Trials CENTRAL, Google Scholar, and Clinicaltrials.gov databases for relevant articles published until the 30th of September 2022. Observational studies (prospective and retrospective) that evaluated the impact of antibiotics on preterm delivery rates of patients with AFS were considered eligible for inclusion. Statistical meta-analysis was performed with RStudio and we calculated pooled risk ratios (OR) and 95% confidence intervals (CI). To evaluate the information size, we performed trial sequential analysis (TSA) and the methodological quality of the included studies was assessed using RoBINS tools. RESULTS: Overall, four retrospective cohort studies were included in the present systematic review and 369 women were enrolled. We demonstrated that preterm delivery prior to 34, 32 and 28 weeks of gestational age was comparable among the groups of women that had antibiotics and those that did not (OR: 0.34, 95% CI 0.05, 2.14, 0.40 [0.09, 1.66], 0.35 [0.08, 1.58], respectively) but the statistical heterogenicity of the studies included was high for every gestational period that was examined. CONCLUSIONS: According to our study, we cannot conclude that the use of antibiotics in women with amniotic fluid sludge benefit the prognostic risk to deliver prematurely. It is quite clear that data from larger sample sizes and more well adjusted and designed studies are needed.

GnRH antagonist rescue of a short-protocol IVF/ICSI cycle and GnRH agonist triggering to prevent ovarian hyperstimulation syndrome: two case reports.

OBJECTIVE: To describe two clinical cases concerning patients at risk of developing severe ovarian hyperstimulation syndrome (OHSS) during in vitro fertilization (IVF) stimulation. DESIGN: Description of clinical management and outcomes of patients using an IVF antagonist rescue protocol to prevent OHSS. SETTING: Reproductive medicine unit, University Hospital. MATERIALS AND METHODS: Two infertile patients undergoing controlled ovarian stimulation (COS) for IVF/intracytoplasmic sperm injection (ICSI) presenting with high risk of OHSS. IVF/ICSI patients following COS under short protocol and high risk of OHSS were managed by withdrawing the agonist and replacing it with an antagonist and triggering ovulation with an agonist bolus. Main outcome measures included incidence of OHSS, oocytes retrieved, and pregnancy rates. RESULTS: None of the two patients developed OHSS. None of the patients had metaphase II retrieved oocytes at oocyte retrieval. CONCLUSIONS: Use of COS with short protocol in an IVF/ICSI cycle carries a risk of severe OHSS. Rescuing the cycle by withdrawing the agonist and replacing it with an antagonist and triggering ovulation with an agonist bolus is not always effective and should not be used if short time interval between agonist replacement with antagonist and ovulation triggering is available.

Seroepidemiological investigation of Toxocara canis in a female Greek pregnant population in the area of Athens.

UNLABELLED: The purpose of this study was to investigate the of areas where the soil is contaminated by Toxocara ova and also to assess seroepidemiological positivity in a Greek pregnant women population (ELISA IgG test). MATERIALS AND METHODS: The authors carried out an examination of soil samples collected from different areas of Athens and Piraeus (Kazakos method). Blood serum was only collected from pregnant women living and conducting activities in places close to the places where the soil sample's were collected for at least a decade (ELISA IgG assay). RESULTS: The authors suggest a correlation between the positive response in the ELISA assay IgG antibodies and the activities of people where soil was contaminated by Toxocara eggs. In conclusion, the prevalence of Toxocara canis infection in a population of Greek pregnant women was found to be a rate of 17.16% and the soil contamination rate of 17.08%.

The impact of metformin treatment on adiponectin and resistin levels in women with polycystic ovary syndrome: a prospective clinical study.

Women with polycystic ovary syndrome (PCOS) are often characterized by adiposity and insulin resistance (IR). Recent studies in patients with obesity and diabetes mellitus type 2 (DMt2) indicate that adiponectin and resistin may play a role in the pathophysiology of IR. The aim of this study was to identify a possible correlation between the plasma levels of adiponectin and resistin and IR in patients with PCOS. Thirty-one women of reproductive age were enrolled in this prospective study after being diagnosed with PCOS and IR according to Rotterdam and American Diabetes Association (ADA) criteria, respectively. Every patient was treated with a daily dose of 1275 mg metformin for 6 months. Adiponectin, resistin, and the primary hormonal and metabolic parameters of the syndrome were evaluated at entry and endpoint of treatment. Adiponectin plasma levels were reduced after metformin treatment, but resistin levels were not significantly affected. Our study suggests that circulating levels of adiponectin should be evaluated with skepticism in patients with PCOS. The adipokine's role in the manifestation of IR in PCOS remains unclear and needs further investigation.

Comparing classic and newer phenotypes in Greek PCOS women: the prevalence of metabolic syndrome and their association with insulin resistance.

OBJECTIVE: Recently, it has been debated whether the new polycystic ovary syndrome (PCOS) phenotypes, according to the Rotterdam criteria, share the same metabolic risk with the classic ones (National Institutes of Health 1990). Our study sought to compare the prevalence of metabolic syndrome (MS) and glucose homeostasis disorders in Greek women with classic and new PCOS phenotypes. MATERIALS AND METHODS: Two hundred and sixty-six Greek PCOS women were recruited and divided into groups according to two of the three Rotterdam criteria that they fulfilled. Two subgroups were formed; the first represented the classic phenotypes and the second the new phenotypes. The clinical, biochemical, and ultrasound characteristics of both groups were explored. All subjects were evaluated for MS and underwent a 2-h glucose tolerance test to assess insulin resistance (IR) as measured by the homeostasis model assessment (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and MATSUDA indices. RESULTS: 62.4% of PCOS women were classified as classic NIH phenotypes of which 32 women had MS (prevalence 19.6%). Only 4 patients categorized in the newer phenotypic groups had MS (prevalence 4.1%). Among the subjects with classic phenotypes, 11.7% exhibited impaired glucose tolerance (3-fold higher percentage compared to patients with newer phenotypes). Regarding IR indices, HOMA-IR was significantly higher and QUICKI significantly lower for classic phenotypes. CONCLUSIONS: Greek PCOS women with classic phenotypes are at increased risk for MS and impaired glucose homeostasis compared to women with newer phenotypes. A subclassification of PCOS permits the earlier recognition and closer surveillance of women whose metabolic profile indicates potential risks for adverse health outcomes.

The prevalence of phenotypic subgroups in Greek women with polycystic ovarian syndrome.

BACKGROUND: Since 2003, when the American Society for Reproductive Medicine (ASRM) and European Society of Human Reproduction and Embryology (ESHRE) sponsored consensus established criteria for polycystic ovarian syndrome (PCOS) diagnosis, the phenotypic spectrum of the syndrome has been significantly broadened. PURPOSE OF THE STUDY: This survey makes an effort to distinguish PCOS according to phenotypic expression and to estimate its prevalence in a Greek population. MATERIALS AND METHODS: Greek women from 18 to 35 years of age, who visited the outpatient department, claiming either irregular menstruation (oligo- or anovulation, OA) or clinical manifestations of hyperandrogenemia (HA) were recruited. They gave full disease history and underwent clinical examination, including transvaginal ultrasound (TVUS) scan to identify PCO morphology. Blood samples were collected to perform hormonal and metabolic analyses. Acute or chronic disorders were excluded. Finally, 266 PCOS women constituted the study population. CONCLUSIONS: The full-blown phenotype (HA+OA+PCO) is the predominant phenotype in this Greek population.

Timing of last COVID-19 vaccine dose and SARS-CoV-2 breakthrough infections in fully (boosted) vaccinated healthcare personnel.

AIM: To estimate the incidence, timing and severity of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) breakthrough infections in fully vaccinated healthcare personnel (HCP). METHODS: In total, 6496 fully vaccinated HCP were analysed prospectively from 15th November 2021 to 17th April 2022. Full coronavirus disease 2019 (COVID-19) vaccination was defined as a complete primary vaccination series followed by a booster dose at least 6 months later. RESULTS: Overall, 1845 SARS-CoV-2 breakthrough infections occurred (28.4 episodes per 100 HCP), of which 1493 (80.9%) were COVID-19 cases and 352 (19.1%) were asymptomatic infections. Of the 1493 HCP with COVID-19, four were hospitalized for 3-6 days (hospitalization rate among HCP with COVID-19: 0.3%). No intubations or deaths occurred. SARS-CoV-2 breakthrough infections occurred at a mean of 16.2 weeks after the last vaccine dose. Multi-variable regression analyses showed that among the 1845 HCP with a breakthrough infection, the administration of a COVID-19 vaccine dose ≥16.2 weeks before the infection was associated with increased likelihood of developing COVID-19 rather than asymptomatic SARS-CoV-2 infection [odds ratio (OR) 1.58, 95% confidence interval (CI) 1.01-2.46; P=0.045] compared with administering a vaccine dose later. The likelihood of developing COVID-19 compared with asymptomatic infection increased by 7% weekly after the last COVID-19 vaccine dose (OR 1.07, 95% CI 1.03-1.11; P=0.001). CONCLUSION: SARS-CoV-2 breakthrough infections are common among fully (boosted) vaccinated HCP. However, full COVID-19 vaccination offered considerable protection against hospitalization. These findings may contribute to defining the optimal timing for booster vaccinations. More efficient COVID-19 vaccines that will also confer protection against SARS-CoV-2 infection are needed urgently.

Endometrioid ovarian cancer arising from an endometriotic cyst in a young patient.

OBJECTIVE: To present a case of a young woman with ovarian endometrioid adenocarcinoma arising from an endometriotic cyst and review of the literature. CASE REPORT: A 33-year-old woman, gravid 2, para 2 was admitted to our department with a 5 cm adnexal mass. Diagnostic laparoscopy was performed and pathological examination demonstrated an endometriotic cyst with an area of an ovarian endometrioid adenocarcinoma well differentiated, with no capsular invasion. One month after the operation the patient underwent MRI which revealed a 6 cm mass in the Douglas pouch. The multidisciplinary oncology council decided on exploratory laparotomy, which revealed no pathology. After that the multidisciplinary oncology council decided on adjuvant chemotherapy and the patient received four cycles of carboplatin/taxol. CONCLUSION: It should always be considered that even when there are no risk factors for malignancy occurrence, a high index of suspicion is necessary and will help to prevent delay in the diagnosis of this rare neoplasm.

Fetal intracranial translucency and cisterna magna at 11 to 14 weeks : reference ranges and correlation with chromosomal abnormalities.

OBJECTIVE: To measure the intracranial translucency (IT) and the cisterna magna (CM), to produce reference ranges and to examine the interobserver and intraobserver variability of those measurements. To examine the possible association of IT with chromosomal abnormalities. METHODS: Prospective study on pregnancies assessed at 11 to 14 weeks. IT was measured retrospectively in 17 cases with aneuploidy. RESULTS: To produce reference ranges, 465 fetuses were used. IT and CM correlated linearly with crown-rump-length (CRL) and were independent of maternal demographic characteristics and biochemical indices. IT had a weak positive correlation with nuchal translucency. For IT the intraclass correlation coefficient was 0.88 for intraobserver variability and 0.83 for interobserver variability. For CM the intraclass correlation coefficient was 0.95 for intraobserver variability and 0.84 for interobserver variability. The IT multiple of the median was significantly increased in the chromosomally abnormal fetuses (1.02 for the normal and 1.28 for the chromosomally abnormal fetuses, Mann Whitney p < 0.001). IT multiple of the median was a significant predictor of chromosomal abnormality (Receiver Operator Characteristic curve analysis: Area under the curve = 0.86, CI=0.76-0.96, p<0.001). CONCLUSION: Intracranial translucency and CM can be measured reliably at the 11 to 14 weeks examination and the measurements are highly reproducible. IT appears to be increased in fetuses with chromosomal abnormalities.

Lymphoid interstitial pneumonitis in a newly diagnosed late presenter of human immunodeficiency virus infection: a case report.

BACKGROUND: An increase has been described throughout the years in the frequency of various uncommon diseases in people living with human immunodeficiency virus (HIV). Particularly late presenters are associated with a significant risk not only for acquired immune deficiency syndrome (AIDS)-defining conditions but also for non AIDS-defining diseases which aggravate the prognosis of patients. Lymphoid interstitial pneumonitis (LIP) is one of these conditions described more often after the onset of HIV epidemic. LIP is a benign polyclonal lymphoproliferative disorder of the lung with not well characterized clinical and radiographic findings. CASE PRESENTATION: We report the diagnostic approach and clinical progress of a newly diagnosed late presenter of HIV infection with respiratory problems in our HIV unit. The findings of computed tomography indicated the diagnosis of HIV-associated LIP, although this condition is mainly described in a normal range of CD4 cell count. CONCLUSION: This case presentation highlights the importance of timely diagnosis and initiation of antiretroviral therapy. The increase of CD4 cell count and viral suppression may improve the symptoms of LIP.

Minimal deviation adenocarcinoma of the cervix in a patient with a high-grade cervical squamous intraepithelial lesion: case report and review of the literature.

Minimal deviation cervical adenocarcinoma, otherwise known as adenoma malignum, is a rare and particularly well differentiated type of cervical adenocarcinoma, and is often misdiagnosed because of its benign-looking histological features. Adenoma malignum represents only 1-3% of all cervical adenocarcinomas. The Papanicolaou smear as well as punch biopsies can fail in the detection of adenoma malignum. We present the case of a 55-year-old woman diagnosed as having microinvasive minimal deviation of the adenocarcinoma cervix, after conisation for a high-grade cervical squamous intraepithelial lesion. The patient was referred for an abnormal pap smear to our colposcopy clinic where the punch biopsies performed failed to diagnose the disease. The consequent cone biopsy because of CIN3, provided us with a definite diagnosis of adenoma malignum. Subsequently, the patient underwent a radical hysterectomy and pelvic lymph node dissection. The histologic examination was normal. Coexistence of a squamous intraepithelial lesion with adenoma malignum is extremely uncommon.

Primary melanoma of the vagina: a case report.

Primary malignant vaginal melanoma is a rare vaginal tumour accompanied by an extremely high risk of local recurrence, distant metastasis and a small survival rate. Due to the fact that vaginal melanoma is quite uncommon there is lack of powerful prospective studies in the literature, thus the treatment choice remains controversial. An 85-year-old woman with a primary malignant vaginal melanoma located on the left lateral aspect of the distal vagina, with the greatest diameter almost 5 cm, was referred to our clinic. There was not any sign of local or distant metastasis identified. According to the most recently published data in the international literature, we decided along with the patient to perform conservative dissection of the tumor with free surgical margins as the appropriate mode of therapy. Radiotherapy, chemotherapy or radical extirpation cannot increase the survival time, even if there is a local or distant spread of melanoma.

The clinical course of smell and taste loss in COVID-19 hospitalized patients.

BACKGROUND: Recent studies have demonstrated an association between a new onset of smell or taste loss and COVID-19. We investigated the prevalence of smell and/or taste loss and the clinical characteristics and recovery in a comprehensive cohort of consecutive patients treated by two COVID-19 reference hospitals and evaluated late persistence of hyposmia. METHODS: A retrospective observational questionnaire study was conducted. All consecutive RT-PCR diagnosed patients who had been hospitalized in March-April 2020 in the COVID-19 care wards were contacted, excluding patients with cognitive disorders and severe deconditioning. The patients responded to a survey about the loss of smell and taste, nasal blockage, and rhinorrhea, rated the symptoms' severity from 0 to 4, and reported the recovery of smell and taste with time. Demographic and clinical characteristics were recorded. RESULTS: We contacted 117 patients. Ninety responded to the questionnaire; 38.9 % of them reported olfactory and 36.66 % gustatory disorders during their disease. Smell loss prior to other symptoms was reported by 42.86 %, and severe hyposmia/anosmia by 74.28 % of the hyposmic. Among the non-ICU treated patients, 43.75 % reported hyposmia. Only 8.89 % had nasal blockage, and 6.66 % rhinorrhea. Most of the patients (85.71 %) recovered their sense of smell in 3-61 days (median: 17; IQR: 24), but 8.57 % had persistent hyposmia. For one out of four, the olfactory loss lasted longer than a month. CONCLUSION: Smell and taste loss are highly prevalent and early symptoms in hospitalized COVID-19 patients. The great majority recover their smell, but nearly one out of ten have not recovered in two months.  HIPPOKRATIA 2020, 24(2): 66-71.

Numerical modelling of simulated blood flow in idealized composite arterial coronary grafts: transient flow.

In composite arterial coronary grafts (CACGs), transport phenomena and geometry may considerably alter blood flow dynamics. CACGs aim at revascularizing pathological arteries according to the human anatomy. However, the exact mechanisms causing the failure of coronary bypass grafting are not yet well elucidated. In the present study, computational fluid dynamics (CFD) techniques are applied for the simulation of multi-branched CACGs under physiologically realistic inflow waveforms. The numerical solution is obtained by a finite-volume method formulated in non-orthogonal, curvilinear coordinates and a multi-grid approach. The geometrical models, consisting of idealized and rigid vessels, include the typical T- and a rather new pi-graft configuration. The stenotic effect is also investigated by comparing computational results for three different degrees of area constriction, namely 25%, 50% and 75%, as well as the case without stenosis. Different grafting distances and various inflow rate ratios are imposed, to give an insight into haemodynamical alterations of CACGs and to study the process of restenosis. The results focus on the interaction between the grafts and coronary flows in terms of spatial and temporal variations of velocity and wall shear stress (WSS) distribution. Prominent variations among the different geometries, concerning the velocity profiles and secondary flow motion, are shown. Moreover, the residual flow emerging from different degrees of area constriction shows that low and oscillating shear stresses may arise for even moderate stenotic fields.

Tricyclic antidepressant-induced acute urine retention in a young woman with postpartum depression--case report.

A rare case of acute urinary retention in a young woman due to simultaneous use of a tricyclic antidepressant and anticholinergic drugs is presented along with the data from the current literature, including the pharmacological action of these drugs, mainly focused on urological patients.

Study on the efficacy of cefaclor for the treatment of asymptomatic bacteriuria and lower urinary tract infections in pregnant women with a history of hypersensitivity to penicillin.

PURPOSE: The purpose of this study was to compare the efficacy and safety profile of twice daily versus the conventional three daily intake of cefaclor administrated orally for five to seven days in the treatment of asymptomatic bacteriuria or acute cystitis in pregnant women with a history of hypersensitivity to penicillin. METHODS: Between August 2003 and August 2004, 63 pregnant women with a positive urine culture and a history of suspicion of hypersensitivity to penicillin were randomly divided into two groups. The women in the first group received 500 mg of cefaclor while those in the second group received 750 mg of cefaclor for five to seven days. Laboratory and clinical results were assessed a week and a month after complettion of the therapy. RESULTS: Final therapy (bacteriologic eradication) succeeded in 93.7% (30/32) of the first group and in 90.3% (28/31) of the second group. CONCLUSION: Dosage of cefaclor at 750 mg is as effective as conventional cefaclor at 500 mg and better tolerated.

Endometriosis of ureter-induced recurrent urinary tract infections in a premenopausal woman--case report.

Endometriosis of the urinary tract is infrequent. The ureters and kidneys are the least usual place of localization. Endometriosis of the ureter often leads to silent loss of renal function due to delayed diagnosis. We report a case of a premenopausal female with endometriosis of the left distal ureter, presenting an infection of the urinary tract and having reported previous incidents of menorrhagia and left flank renal pain with automatic recession. Pharmacological treatment was applied with a satisfactory outcome. A short review of the literature is presented.

Low-Grade Appendiceal Mucinous Neoplasm Presenting as an Adnexal Mass.

Appendiceal tumors are rare, late diagnosed neoplasms that may not be differentiated from adnexal masses even by advanced imaging methods and other diagnostic procedures. They may be asymptomatic and remain undiagnosed until surgery. We report a case of an 80-year-old postmenopausal woman presenting with a pelvic mass and a history of weight loss. The patient underwent laparotomy which revealed an appendiceal mucocele, for which she received a full oncological procedure. The histology report showed a low-grade appendiceal mucinous neoplasm, and the patient underwent six cycles of chemotherapy. Appendiceal tumors should be kept in mind in patients with adnexal mass.
