Chorangioma is a rare non-trophoblastic benign vascular neoplasm originating from the primitive chorionic mesenchyme. Usually asymptomatic, it affects approximately 1% of female fetuses. We present the case of a giant placental chorangioma (GPC) in a preterm male pregnancy coexisting with a maternal neuroendocrine carcinoma. A 30-week primigravida was admitted to the Obstetrics and Gynecology Clinic of the Targu-Mures Emergency Clinical Hospital, with abdominal discomfort, and an emergency C-section was performed for fetal congestive heart failure. Medical history revealed an advanced-stage rectal neuroendocrine carcinoma. At 20th gestational week, a well-vascularized placental mass was diagnosed. A 1500g premature male fetus was delivered. Histopathologically, the placental mass revealed an unencapsulated but well-circumscribed tumor with lobular architecture composed of congested vascular capillaries and thin-walled vessels. Diagnosis of giant placental chorangioma (GPC) was rendered. GPC is a challenging condition typically occurring in hypertensive or diabetic primigravidas with female fetuses. Antenatal management is suggested at an early stage for a desirable perinatal outcome.

Complex bone injuries in the hand and forearm pose considerable physical and psychological challenges to patients. However, there is limited research on the psychological effects of these injuries. This study seeks to clarify the psychological impact and frequency of injuries in various hand bones. This cross-sectional study included 166 patients with complex hand and forearm injuries. Injuries were classified based on amputations and fractures involving phalanges, fingers, and other bones. Psychological assessments utilised standardised tools to gauge post-traumatic stress disorder (PTSD) levels. Our findings suggest that injury rates differ among the phalanges and individual fingers. The intermediate phalanx (P2) of the thumb had the most injuries, while no injuries were found in the proximal phalanx (P1) of the small finger. Amputations and fractures were found to be positively associated with increased symptoms of PTSD. This study emphasises the importance of recognising the psychological effects of hand and forearm bone injuries. The data indicate the need for a multi-disciplinary treatment approach that includes psychological interventions for optimal patient care. The study emphasises the necessity for additional research to further investigate these matters.

Our study seeks to study the accuracy of the ellipsoidal formula in prostate MRI of different sizes and to establish the limits of its use. The study included 31 patients with a well-visualized, intact prostatic capsule, excluding malignantly transformed prostates, as well as treated prostates, in which the contrast between the prostatic capsule and parenchyma is reduced. Each patient's prostatic volume was recalculated according to the ellipsoidal formula, and then it was compared with the prostatic volume calculated by the segmentation method. The two calculated volumes were similar, in some cases almost identical, with a slight tendency to underestimate prostate volume below 100cm3, in total in 18 cases, on average by 7.6% (+/-6%), overestimation of those with a volume over 100cm3, a total of 13 cases, on average by 3.2% (+/-2.5%), and of all, in 4 cases the difference between the two formulas was below 1%. There was no statistical difference between the two variables, Student's t-test p-value=0.039. With a precision of 92% (+/-6%), the ellipsoidal formula can be considered accurate when it is correctly performed, but if we take into account the importance that PSA density is starting to have in diagnosis, treatment and follow-up, the calculation of a secondary value through the segmentation method or high-precision software can be motivated when the ellipsoidal formula returns a value close to a threshold.

The premise of this paper starts from the fact that a more precise definition related to the intensity of the lesions on the ADC sequence can lead to a new subclassification of PI-RADS 3 lesions in the transitional zone and to an improvement of the specificity of the PI-RADS classification. The study was retrospective and included only patients who, based on prostate MRI examinations, contained exclusively PI-RADS 3 lesions, without other PI-RADS 4 or 5 lesions. The number of cases that meet all these conditions was reduced to 18, where a series of characteristics were noted for each one: PI-RADS 3 lesion area on the ADC sequence, the minimum and average ADC value of the lesion, the average ADC value of the transitional zone outside the lesion, PSA, prostatic volume, PSA density and biopsy result. The average ADC value of the negative lesions was 865(165) m2/sec, and of the positive ones was 869(118) m2/sec, which denies the hypothesis that there could be a value limit ADC to delimit PI-RADS 3 from PI-RADS 2 or 4 in this sample of patients. Furthermore, we reported the average ADC value of each such lesion to the adjacent unchanged transitional zone and obtained a greater difference of 432(163) m2/sec between the negative lesions and their adjacent transitional zone, compared to the difference of 399(127) m2/sec between the positive lesions and their adjacent ones.

Adenoid cystic carcinoma (ACC) is an uncommon malignant tumor that accounts for less than 5% of head and neck cancers. ACC is characteristic for its indolent nature and its propensity for late distant metastases. Late diagnosis, tendency to perineural invasion, periosteal infiltration and local recurrence are factors of poor prognosis. Although studies still discuss the ideal treatment, the initial therapy consists of surgical resection, followed by postoperative radiotherapy.

Decompressive craniectomy has been increasingly used in recent decades for the treatment of uncontrollable intracranial hypertension caused by trauma, malignant strokes, cerebral venous thrombosis, among others. Sinking flap syndrome (SFS) is a rare complication characterized by neurological deterioration after craniectomy. Here, we report the case of a 73-year-old female patient who presented with disorientation, lip rhyme deviation to the right and left hemiparesis after cardiac catheterization. In view of the presence of a malignant stroke, as well as the willingness of the family members to make a total investment to save the patient's life, decompressive hemicraniectomy was indicated. Subsequently, due to occasional headache attacks, nausea and vomiting, in addition to progressive depression of the subcutaneous flap, the possibility of SFS was suggested and cranioplasty was indicated, which occurred without perioperative intercurrences. Although the patient maintained a stable neurological status, a post-surgical computed tomography (CT) scan of the head showed a right intraparenchymal hemorrhagic lesion, associated with parenchymal expansion and midline deviation. To the best of our knowledge, intraparenchymal hemorrhages are not common complications after performing cranioplasty, and additional studies are needed to understand the reasons why this occurs. The mechanisms responsible for this type of injury are not well understood, but involve reperfusion damage and loss of brain compliance. Despite representing an uncommon complication, post-cranioplasty hemorrhage can cause severe morbidity to the patient, and early diagnosis and intervention are of great importance in these cases.

Since stroke has limited treatment options, an active search for new therapeutic approaches is required. Initial excitement of using cell-based therapies to stimulate recovery processes in the ischemic brain turned into a more measured perspective, acknowledging obstacles related to the unfavorable environments associated in part with aging. Given the predominance of stroke in older populations, evaluating the effectiveness of cell therapies in aged brain environments is essential and clinically relevant. Despite a common perception of the aged brain being resistant to regeneration, recent research with neural precursor cells and bone marrow-derived mesenchymal stem cells indicates that cell-based therapy can promote plasticity and remodeling in the aged rat brain. However, significant differences in the aged brain compared to the young brain, such as expedited progression of ischemic injury to brain infarction, decreased rate of endogenous neurogenesis, and delayed onset of neurological recovery, must be noted. The effectiveness of cell-based therapies may further be connected to age-related comorbidities such as diabetes or hyperlipidemia, potentially leading to maladaptive or impaired brain remodeling. These age-related factors need careful consideration in the clinical application of restorative therapies for stroke.

Melanoma, a deadly form of skin cancer, poses significant challenges to the host immune system, allowing tumor cells to evade immune surveillance and persist. This complex interplay between melanoma and the immune system involves a multitude of mechanisms that impair immune recognition and promote tumor progression. This review summarizes the intricate strategies employed by melanoma cells to evade the immune response, including defective immune recognition, immune checkpoint activation, and the role of regulatory T-cells, myeloid-derived suppressor cells, and exosomes in suppressing anti-tumor immunity. Additionally, we discuss potential therapeutic targets aimed at reversing immune evasion in melanoma, highlighting the importance of understanding these mechanisms for developing more effective immunotherapies. Improved insights into the interactions between melanoma and the immune system will aid in the development of novel treatment strategies to enhance anti-tumor immune responses and improve patient outcomes.

Gastric cancer (GC) is the fourth most common cause of cancer death worldwide, with about 769,000 deaths/year worldwide. Recent studies showed a continuous decrease in the incidence and mortality of gastric cancer mainly in developed countries, while the incidence remains increased in some countries in Eastern Asia and Eastern Europe. For the assessment of some parameters of gastric cancer in Gorj county, all the medical records of patients diagnosed with gastric cancer, found in the Archive of the County Emergency Hospital of Tg Jiu, were analyzed, namely the admission records within the Surgery and Oncology departments, the observation sheets of every individual patient, the biological test reports, the histopathological records of the patients with gastric cancer undergoing surgery, the histopathological records of gastric biopsies, the medical imaging records (ultrasound, x-ray, computer tomography and magnetic resonance). The analysis of the medical records showed that the disease mainly affects men, the ratio of men/women being 2/1-3/1. Most cases undergoing surgery within the County Hospital of Tg. Jiu were diagnosed in stages III or IV. The most numerous cases (over 85% of the total group of patients) were identified in people over 61 years old. The most common histopathological form of cancer was adenocarcinoma (95% of all gastric tumors).
胃癌(GC)是全球第四大常见癌症死因,每年约有 769,000 人死于胃癌。最近的研究表明,主要在发达国家,胃癌的发病率和死亡率持续下降,而在东亚和东欧的一些国家,发病率仍在上升。为了评估戈尔杰县胃癌的一些参数,我们分析了在茨久县急救医院档案馆找到的所有确诊胃癌患者的病历,即外科和肿瘤科的入院记录、每个患者的观察表、生物检测报告、接受手术的胃癌患者的组织病理学记录、胃活检的组织病理学记录、医学影像记录(超声波、X光、计算机断层扫描和磁共振)。病历分析表明,胃癌患者以男性为主,男女比例为 2/1-3/1。在 Tg. Jiu 县医院接受手术的大多数病例被诊断为 III 期。九县医院接受手术的大多数病例被诊断为 III 期或 IV 期。61岁以上的患者最多(占患者总数的85%以上)。最常见的癌症组织病理学类型是腺癌(占所有胃肿瘤的 95%)。

Jiu were diagnosed in stages III or IV. The most numerous cases (over 85% of the total group of patients) were identified in people over 61 years old. The most common histopathological form of cancer was adenocarcinoma (95% of all gastric tumors).</p>","PeriodicalId":93963,"journal":{"name":"Current health sciences journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10863741/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139731265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nosebleed or epistaxis is one of the most common forms of presenting an emergency in the ENT field. Since March 11, 2020, the World Health Organisation has proclaimed COVID-19 a global pandemic, and the world has been closed down. The main objective of the study is to analyse and compare the dynamics of epistaxis aetiology among the cases that required hospitalisation in the pre-pandemic period and the period of the COVID 19 pandemic. The study is multicenter retrospective from October 2018 to May 2022, including 380 cases of hospitalised epistaxis, with the mention that March 2020 is considered the beginning of the pandemic period. 60.8% of the patients enrolled in the study in the pre-pandemic period (60.8%) and 39.2% in the pandemic period. Differences between groups were not statistically significant between study entries (pre-pandemic vs. pandemic) and age (p=0.331), gender (p=0.916) or existence of local causes for epistaxis (p=0.895). Patients with general causes for epistaxis were more frequently enrolled in the pandemic period, while patients without general causes for epistaxis were more frequently enrolled in the pre-pandemic period. Patients with a hospitalisation period of more than 5 days were more frequently enrolled in the pre-pandemic period while patients with a hospitalisation period of 3 to 5 days were more frequently enrolled in the pandemic period. Also, patients with idiopathic epistaxis were more frequently enrolled in the pre-pandemic period. Based on the results presented in our study, the period of the Covid 19 pandemic directly influenced both the number of patients and the period of hospitalisation.
