Kisspeptin Variations in Patients with Polycystic Ovary Syndrome-A Prospective Case Control Study.

Background and objectives: Kisspeptin, also named metastin, showed important roles in initiating the secretion of gonadotropin-releasing hormone (GnRH) and is an essential factor in the development of polycystic ovaries syndrome (PCOS). Several research studies noticed associations between kisspeptin levels and patients with anovulatory cycles due to PCOS with an increased LH/FSH ratio. The aim of our study was to bring scientific evidence regarding the correlation between high kisspeptin and luteinizing hormone values in subfertile women due to PCOS. Materials and Methods: A prospective case-control study was conducted in "Elena Doamna" Hospital of Obstetrics and Gynecology between 4 January 2021 and 1 March 2022. All patients agreed to participate in our study, had ages between 18 and 45 years old, and had a body mass index between 18.5 and 30 kg/m2. The study group consisted of subfertile patients with PCOS and menstrual disturbances, including amenorrhea or oligomenorrhea. The control group consisted of healthy patients with ovulatory cycles and no other reproductive or endocrinology pathologies. During the follicular phase of their menstrual cycle, patients had blood samples taken with the dosage of kisspeptin, LH, FSH, estradiol, insulin, glycemic levels, testosterone, and prolactin. Pelvic ultrasounds and clinical examinations were performed as well. Results: Significant differences were observed in kisspeptin, LH, FSH, and estradiol levels between patients with PCOS and the control group. After the univariate analysis, PCOS was significantly associated with increased kisspeptin, increased LH, and decreased FSH. There was no significant association between PCOS, estradiol, prolactin, and insulin. Conclusions: kisspeptin serum values are higher in subfertile PCOS patients, supporting the hypothesis that an over-stimulation of the KISS1 system might cause the hyper-stimulation of the HPG-axis.

Hybrid Management of an Aortobronchial Fistula after Patch Aortoplasty for Aortic Coarctation in a Patient with SARS-CoV-2 Pneumonia: Case Report and Review of the Literature.

Aortobronchial fistula is a rare cause of repeated hemoptysis and a potentially fatal condition if left untreated. We present the case of a 40-year-old man with repeated hemoptysis, excessive cough, and epistaxis ongoing for several days after SARS-CoV-2 pneumonia diagnosis. The patient had a history of patch aortoplasty for aortic coarctation and aortic valve replacement with a mechanical valve for aortic insufficiency due to bicuspid aortic valve at the age of 24. Computed tomography scan performed at presentation revealed a severely dilated ascending aorta, a thoracic aorta pseudoaneurysm at the site of the former coarctation, an aortobronchial fistula suggested by the thickened left lower lobe apical segmental bronchus in contact with the pseudoaneurysm and signs of alveolar hemorrhage in the respective segment. The patient was treated with thoracic endovascular aneurysm repair (TEVAR) after prior hemi-aortic arch debranching and transposition of the left common carotid artery and subclavian artery through a closed-chest surgical approach. Our case report together with a systematic review of the literature highlight the importance of both considering an aortobronchial fistula in the differential diagnosis of hemoptysis in patients with prior history of thoracic aorta surgical intervention, regardless of associated pathology, and of taking into account endovascular and hybrid techniques as an alternative to open surgical repair, which carries a high risk of morbidity and mortality.

Pictorial essay of ultrasound-reconstructed coronal plane images of the uterus in different uterine pathologies.

Imaging in the major planes (horizontal, coronal, and sagittal) of the uterus is important for determining anatomy and allowing the findings to be standardized, and for evaluating and diagnosing different pathological conditions in clinical practice. Examination of the coronal plane is an important step in identifying uterine pathologies and their relationships to the endometrial canal. Three-dimensional (3D) ultrasound reveals the normal anatomy better and improves the depiction of abnormal anatomy, as the coronal plane of the uterus can easily be obtained using 3D reconstruction techniques. Our pictorial essay demonstrates that adding 3D ultrasound to a routine gynecological workup can be beneficial for clinicians, enabling a precise diagnosis to be made. In addition, the volumes obtained and stored by 3D ultrasound can allow students or residents to become more familiar with normal and abnormal pelvic structures. Clin.

The Impact of the Early COVID-19 Pandemic on ST-Segment Elevation Myocardial Infarction Presentation and Outcomes-A Systematic Review and Meta-Analysis.

Background: The influence of the early COVID-19 pandemic on non-COVID-19 emergencies is uncertain. We conducted a systematic review and a meta-analysis to evaluate the impact of the first months of the COVID-19 pandemic on the presentation, management, and prognosis of patients presenting with ST-segment elevation myocardial infarction (STEMI). Methods: We searched the PubMed, Scopus, and Embase databases from January to August 2020. A meta-analysis of studies comparing the profile, STEMI severity at presentation, reperfusion delay, and in-hospital mortality for patients presenting before and during the early COVID-19 pandemic was conducted. Fifteen cross-sectional observational studies including 20,528 STEMI patients from the pre-COVID period and 2190 patients diagnosed and treated during the first months of the COVID-19 pandemic met the inclusion criteria. Results: Patients presenting with STEMI during the pandemic were younger and had a higher comorbidity burden. The time interval between symptoms and first medical contact increased from 93.22 ± 137.37 min to 142 ± 281.60 min (p < 0.001). Door-to-balloon time did not differ significantly between the two periods (p = 0.293). The pooled odds ratio (OR) for low left ventricular ejection fraction at presentation during the pandemic was 2.24 (95% confidence interval (CI) 1.54−3.26) and for a presentation delay >24 h was 2.9 (95% CI 1.54−5.45) relative to before the pandemic. In-hospital mortality did not increase significantly during the outbreak (p = 0.97). Conclusion: During the first months of the COVID-19 pandemic, patients presenting with STEMI were addressed later in the course of the disease with more severe left ventricular impairment. In-hospital emergency circuits and care functioned properly with no increase in door-to-balloon time and early mortality.

Surgical versus Transvalvular Aortic Valve Replacement in Elderly Patients-The Impact of Frailty.

(1) Background: The aging process leads to an increased number of patients with cardiovascular diseases that require surgical treatment. One of the most common heart diseases with an increased prevalence in the elderly is aortic stenosis (AS). Recently, transcatheter aortic valve implantation (TAVI) has become the preferred technique for frail patients with high surgical risk. Currently, there is no gold standard method for assessing frailty. The available scores are objective, but limited by the lack of prospective information, especially from patients undergoing cardiac surgery or interventional procedures. Moreover, the current frailty scores record only certain aspects of the frailty identified in some system and organs. The aims of this study were to evaluate the different profile patients treated with TAVI or with surgical aortic valve replacement (SAVR) and to analyze the risk factors of unfavorable outcomes in the two groups to identify potential factors for frailty that could be included in the new scoring system. (2) Methods: This study included patients over 65 years old evaluated with severe, symptomatic AS treated with TAVI or SAVR admitted to the Cardiovascular Diseases Institute, Iasi. (3) Results: The group included 88 patients treated with TAVI compared with 218 patients undergoing SAVR. Most of the TAVI patients (84.09%) were over 70 years compared to 30.09% of the SAVR group. The TAVI patients had an increased surgical risk assessed by EuroSCORE II (15 vs. 4%) and severe heart failure (NYHA IV, 36.36 vs. 6.48%). The only residual symptom was dyspnea, in a significantly lower prevalence compared to preoperative evaluation. (4) Conclusions: TAVI improves the general status with results comparable to SAVR in elderly patients with increased severity of the disease and higher prevalence of comorbidities.

Morphological aspects of the vasculogenesis and angiogenesis during prenatal edification of the circle of Willis: a review.

In the literature, there are many articles reporting anatomical variations of circle of Willis (CoW), defined as those changes that lead to the inability of this anastomotic structure to maintain adequate brain flow. Because there is such a wide variation in the configuration of the CoW, its anatomical variations affect the hemodynamics of blood flow, thus contributing to the development of aneurysms or stroke. As such, we consider that a good knowledge of the embryological development of the constituent arteries of the CoW can shed some light on the causes of the appearance of its anatomical variants. Reviewing literature, we will present the embryological development of the constituting arteries of the CoW and will begin with vasculogenesis and angiogenesis of the vascular system as a whole. Then, we will focus on the embryological development of the internal carotid artery (ICA) and its branches because, starting with the embryological day 24, these arteries are the first vessels that begin to develop to provide the necessary blood for the primitive brain. As the hindbrain increases its volume, a larger amount of nutrients is needed. Because a larger amount of blood is required to be provided by the primitive ICAs, there is a need for arterial capacity development and thus the posterior circulation begin to take shape. At this stage, the posterior circulation consists of a plexiform arterial network that receives blood from the carotid artery through the carotid-vertebrobasilar anastomoses. At the 5-8 mm embryonic stage, these anastomoses begin to regress, and the basilar artery and vertebral arteries become independent of the ICA. We are pointing out on the process of regression of these primitive vessels, emphasizing the fact that their persistence represents the starting point for the appearance of anatomic anomalies of the CoW, which are identified in the adult individuals. In this review, we also present and illustrate some developmental abnormalities of the anterior and posterior parts of the CoW.

"Carpe Diem" Professor - In Memoriam of Francis Robicsek (1925-2020).

Francis Robicsek was an outstanding cardiothoracic and vascular surgeon, anthropologist, biomedical engineer, philanthropist, art lover, and collector. During a career of almost 55 years, he managed to influence almost every aspect of cardiothoracic and vascular surgery. He is best known for his novel approach to the treatment of sternal instability, the Robicsek weave, which is currently the reference standard. His accomplishments include over 35,000 surgical interventions, 672 medical publications, 734 lectures, 4 textbooks on Mayan culture, and approximately 100 pupils. His remains one of the most fascinating stories in modern surgery.

Science, biomedical technology and biolaw.

Starting from legislative recognition of the grounding principles of human rights, the authors describe and comment upon the Council of Europe's Convention on human rights and human dignity confronted with scientific discoveries and also upon the Oviedo Convention of 1997 for the protection of Human Rights and dignity of the human being with regard to the application of biology and medicine. The authors specify that, given the promise made by Romania to observe international obligations, the Romanian law no. 2/1998 on organ and tissue transplantation abrogates the stipulations of the law 3-1978 and also includes 9 appendices which, being part of the law, guarantee in addition the observance of its provisions. All these regulations on the relationship between science and human rights have determined an evolution from the fatality of natural risks to current compensations, as an expression of human solidarity. They have determined the transition from social and vocational paternalism to personal autonomy and personal guarantees of independence and freedom. All these developments are faithfully reflected by comparative legislation on the use of life science outcomes on persons as they presently are. This is also reflected in Romanian legislation concerning tissue and organ transplantation and in mental health legislation.

Long-term graft patency after coronary artery bypass grafting: Effects of surgical technique.

The aim of the current study was to identify surgical factors associated with long-term patency of grafts used in coronary artery bypass grafting (CABG). The present study analyzed data from 127 patients who underwent CABG at our institute between 2000 and 2006 and presented for ambulatory examination and coronary computed tomography angiography evaluation of graft patency in 2016 (139.78±36.64 months post-CABG). The 127 patients received 340 grafts (2.68 grafts/patient) and 399 distal anastomoses (3.14 anastomoses/patient), 220 (55.14%) with arterial grafts and 179 (44.86%) with saphenous vein grafts. Graft patency varied according to coronary territory, proximal anastomosis type (in situ graft, composite graft, graft anastomosed to the ascending aorta), Y anastomosis angle (47.21° for patent arterial grafts vs. 56° for occluded), and distal anastomosis angle (in sequential anastomoses irrespective to graft type, 48.60° for patent side-to-side anastomosis vs. 53.97° for occluded, 65.12° for patent end-to-side anastomosis vs. 90.80° for occluded; in single end-to-side anastomosis of arterial grafts, 39.46° for patent and 44.94° for occluded). A single end-to-side anastomosis angle 60° or greater was associated with a 5.149 occlusion odds ratio (OR) (P<0.001) for arterial grafts. Venous grafts were not sensitive to single end-to-side anastomosis angle. In conclusion, a small anastomosis angle for proximal Y and distal anastomoses is associated with a higher long-term patency of the free graft. Radial artery grafts registered higher patency rates when anastomosed to the ascending aorta compared with composite grafting with the left internal thoracic artery, whereas in situ right internal thoracic artery (RITA) anastomosed to the right coronary territory is associated with a lower patency rate compared with free RITA used to revascularise the anterolateral or circumflex territory in composite grafting.

Pentalogy of Cantrell associated with unilateral anophthalmia: Case report and literature review.

RATIONALE: Pentalogy of Cantrell, a very rare congenital condition, has an estimated incidence of 5.5 per 1 million live births. It includes five defects: a midline supraumbilical wall defect, a diaphragmatic defect, a cleft distal sternum, a defect in the diaphragmatic pericardium, and an intracardiac defect. Very few cases of this condition have been reported in the literature, most of them diagnosed in the second or third trimester of pregnancy. PATIENT CONCERNS: We present a case of pentalogy of Cantrell associated with cranioschisis and unilateral anophthalmia diagnosed at 14 weeks of amenorrhea. DIAGNOSES: The combination of abdominal and vaginal sonography established the diagnosis of 14 weeks of amenorrhea with a plurimalformative syndrome including: ectopia cordis, large suprambilical anterior abdominal wall defect, omphalocele, anomaly of the shape of the skull, and anomalies of the brain. INTERVENTIONS: After counseling the parents, the pregnancy was interrupted, as requested by the family. OUTCOMES: Pathological examination of the fetus after the therapeutic abortion confirmed the diagnosis. LESSONS: Because of the poor prognosis of Cantrell's pentalogy, early antenatal sonographic detection is important and allows for elective abortion before viability.

Early prenatal diagnosis of a lumbo-costo-vertebral syndrome.

Lumbo-costo-vertebral syndrome (LCVS) is a rare type of lumbar hernia with associated abnormalities of the vertebral bodies, ribs, and trunk muscles. Only a few cases have been reported in the literature, all of which were diagnosed after birth. We present a case of LCVS diagnosed early in the second trimester of pregnancy using two- and three-dimensional ultrasound. In our case, the associated anomalies were: multiple costovertebral anomalies, lumbar hernia, anal imperforation, left hand supernumerary digit, and clubfoot.

Long-term graft patency after coronary artery bypass grafting: Effects of morphological and pathophysiological factors.

OBJECTIVE: The aim of the present study was to identify morphological and pathophysiological factors associated with long-term patency of grafts used in coronary artery bypass grafting (CABG). METHODS: A total of 127 patients who underwent CABG between 2000 and 2006 and presented for computed tomography evaluation of graft patency at 139.78±36.64 months post-CABG were analyzed. Patients received 340 grafts (2.68 grafts/patient), 399 distal anastomoses (3.14 anastomoses/ patient), 220 (55.14%) performed using arterial grafts, and 179 (44.86%) using saphenous vein grafts (SVGs). RESULTS: Graft patency varied according to vessel type and coronary territory. Overall graft patency was 90.16% for the left internal thoracic artery (LITA), 75.55% for the right internal thoracic artery (RITA), 79.25% for the radial artery (RA), and 74.3% for the SVG. The maximum patency rate was obtained with the RA (80.65%) for the right coronary territory, RITA (92.86%) for the anterolateral territory, and SVG (82.54%) for the circumflex territory. The LITA-left anterior descending artery graft occluded in 13 (7.93%) cases, 7 due to competitive flow. The influence of graft length on patency rates after indexing to height was not significant. The target vessel degree of stenosis influenced arterial graft patency rates with an occlusion odds ratio (OR) of 3.02 when anastomosed to target vessels with <90% stenosis. Target vessel caliber also influenced patency rates with occlusion ORs of 2.63 for SVGs and 2.31 for arterial grafts when anastomosed to ≤1.5 mm target vessels. CONCLUSION: Morphological parameters, such as graft type, target territory, target vessel caliber, and degree of stenosis, are important factors conditioning long-term graft patency.

Three-dimensional ultrasound and HDlive in tubal serous cystadenofibroma: a case report and literature review.

Cystadenofibromas of the fallopian tubes are very rare benign tumors and very few cases have been reported in the literature worldwide. Usually, the tumor is asymptomatic, and for almost all cases reported, the tumors were incidentally discovered during surgery for other genital pathology. We report the case of a 30-year-old woman with a serous cystadenofibroma of the fallopian tube, presenting with chronic abdominal pain and secondary infertility. The diagnosis of tubal tumor was formulated before surgery and confirmed during laparoscopic surgery. Both 3D ultrasound and HDlive were useful tools for the diagnosis. The ultrasound diagnosis was helpful in planning appropriate surgical management.

LEFT ATRIAL, LEFT ATRIAL APPENDAGE AND PULMONARY VEINS ANATOMICAL VARIANTS IN PATIENTS WITH ATRIAL FIBRILLATION VERSUS PATIENTS IN SINUS RHYTHM.

The aim of the study is to evaluate by multidetector computed tomography (MDCT) the prevalence, location and size of LA (left atrial) diverticula and accessory appendages, the prevalence of PVs anatomical variants and LAA (left atrial appendage) shapes in patients with atrial fibrillation (AF) compared to patients in sinus rhythm (SR). Images obtained by MDCT in a group of 100 patients with <1 year paroxysmal or persistent AF prior to radiofrequency catheter ablation and in a group of 100 patients in SR with unconfirmed or insignificant (<50%) coronary arteries stenoses were compared. The prevalence of LA diverticula (22% in AF group, 19% in SR group) and accessory appendages (6% in AF group, 5% in SR group) was not significantly different between the two groups. Similar sizes of LA diverticula and accessory appendages were registered in patients with AF and in SR. The prevalence of a common left venous trunk was significantly higher in patients with AF (30%) compared to patients in SR (18%) (p=0.047) and proved to be an independent predictor for AF (odds ratio (OR) 1.32; 95% confidence interval (CI) 0.93-1.51; p=0.002) at multivariate logistic regression. LAA had a complex shape but no significant differences concerning the prevalence of the 4 major types were registered between the groups. In conclusion, the only parameter associated with AF was the presence of a left common trunk suggesting that it is either a consequence or a predisposing factor for the development of AF.

What Can We Find Behind a Parietal Abscess? Case Report.

We report a rare case of a 71-year-old female who presented to the First Clinic of Surgery from "Sf. Spiridon" Hospital Iasi, Romania with a mass in the left iliac fossa that started to discharge a feculent secretion five days prior to presentation. The patient had a history of constipation, several episodes of hematochezia associated with significant weight loss over the past 6 months. Following evaluation, a diagnosis of enter cutaneous fistula secondary to a locally advanced sigmoid cancer was made. The patient underwent semi-elective resection of the sigmoid tumor (measuring 20 cm) with 10 cm safe margins, and of the involved lymph nodes and abdominal wall. A termino-terminal colo-rectal anastomosis was performed. The patient was discharged the 10th postoperative day after an uneventful evolution for oncological evaluation. The authors presented this case in order to illustrate the challenges associated with diagnostic and therapeutic management of advanced colorectal cancer that has been discovered through a parietal abscess.

Trigeminal nerve: MRI anatomy and case presentation of trigeminal neuralgia due to arterial compression.

Trigeminal neuralgia (TN), also known as tic douloureux is a chronic neuropathic pain disorder characterized by sporadic episodes of extreme, sudden burning or shock-like face pain that last from a few seconds to 2 minutes. Trigeminal neuralgia has a reported incidence of 5.9/100,000 women and 3.4/100,000 men in USA. The exact pathophysiology is still unclear, but demyelization leading to abnormal discharge in fibers of the trigeminal nerve is a probable cause. In the majority of cases, no structural lesion is detected but in almost 15% of patients medical imaging methods like MRI, CT or angiography can identify a vein or artery that compresses the nerve which results in focal demyelization. The authors present a case of trigeminal neuralgia investigated by MRI, which identified a vascular compression of the nerve 9 mm after emerging the pons by the superior cerebellar artery (SCA) and one of its branches. The authors also realize a review of the MRI anatomy of the trigeminal nerve.

Considerations associated with computer forensic facial reconstructions the limits of soft tissues' thickness determination.

UNLABELLED: Revolutionary progresses in computer technology are of great use during forensic investigations in terms of facial identification based on reconstructions. AIM: The purpose of the current study is to evaluate the use and limits of facial reconstruction by considering soft tissues' thickness determination. MATERIAL AND METHOD: The authors investigated the limits of three methods used for soft tissues' thickness determination on a sample group consisting of 9 cadavers, 30 ultrasound investigations and 27 cranial X-rays. The measurements were performed at standard anthropological landmarks following methods previously described in literature. RESULTS: Measurement values for each soft tissue landmark overlapped between sexes, females having greater soft tissue thickness at two sites: infraorbital and supraorbital notches. US measurements demonstrate a much larger dependence of the soft tissue thickness according to different body posture and imply compressing soft tissues with the transducer. X-rays determinations revealed more accurate values than US, but are nocive to the subjects and can only be performed in standard radiographic positions. For cadavers, different postmortem stages and supine position generated inadequate results. CONCLUSION: In order to increase the degree of accuracy of craniofacial approximation it is necessary to obtain a validated data set specific for the Romanian population. This will allow a better determination of facial measurements opening new perspectives in understanding the relation between physical properties and facial soft tissue.

[New trends in the scientific anthropo-cultural psychiatric expertise]. / Orientarea antropo-culturala actualna si stiintifica a psihiatriei expertale.

Starting from the "epistemological naturalization of sciences of life", the authors present the complex content of medico-legal psychiatric examination, from which will result its scientific structure. The ontological, epistemological, hermeneutical and axiological content of this type of examination emphasize its methodological structure in the purpose of combining in a creative way its humanistic and scientific features.
