RESUMO

This study aimed to investigate the behavior of chitosan/quaternized chitosan fibers in media mimicking wound exudates to understand their capacities as wound dressing. Fiber analysis of the fibers using dynamic vapor sorption proved their ability to adsorb moisture up to 60% and then to desorb it as a function of humidity, indicating their outstanding breathability. Dissolution analyses showed that quaternized chitosan leached from the fibers in water and PBS, whereas only small portions of chitosan were solubilized in water. In media containing lysozyme, the fibers degraded with a rate determined by their composition and pH, reaching a mass loss of up to 47% in media of physiologic pH. Notably, in media mimicking the wound exudate during healing, they adsorbed moisture even when their mass loss due to biodegradation was high, whereas they were completely degraded in the media of normal tissues, indicating bioabsorbable dressing capacities. A mathematical model was constructed, which characterized the degradation rate and morphology changes of chitosan/quaternized chitosan fibers through analyses of dynamics in scale space, using the Theory of Scale Relativity. The model was validated using experimental data, making it possible to generalize it to the degradation of other biopolymeric systems that address wound healing.

RESUMO

Spinal metastases from gastrointestinal (GI) cancer are rare and as a result there are only case reports or small series in the literature. The aim of our work was to identify the demographic aspects, the location, and the histopathological aspects of spinal metastases from GI cancers diagnosed and treated in a reference Hospital in Romania over a period of nine years, and comparing the data obtained with those from the recent literature. This is a retrospective case series study on spinal metastases from GI cancers, developed in patients older than 18 years that were surgically treated between January 2013 and December 2021 within three Neurosurgery Clinics from Prof. Dr. Nicolae Oblu Emergency Clinical Hospital, Iasi, Romania, which is a tertiary Hospital in Romania regarding the surgical treatment of spinal metastases. We included in our study the patient's demographic data (age and gender), clinical data (location of spinal metastases), radiological investigations and pathological features of the lesions. Regarding the immunohistochemical stainings, the following antibodies were used: anti-cytokeratin (CK)7, anti-CK20, anti-CK19, anti-caudal-type homeobox 2 (CDX2), anti-human epidermal growth factor receptor 2 (HER2), and anti-Ki67. Our series included 40 adult patients (≥18 years old) with a male:female ratio of 3:1, in favor of male patients. The mean age of all patients was 66.42 years. The primary sites of spinal metastases from GI cancers were from all segments of the GI system: the most frequent, however, was from the colorectal level (40%) and the least from the oral cavity level (2.5%). The most common site of spinal metastases from GI cancer was predominantly lumbar region (47.5%), and the most frequent histological type was adenocarcinoma (57.5%), followed by hepatocellular carcinoma (27.5%), pancreatic ductal carcinoma (5%) and squamous cell carcinoma (2.5%). Our results have important clinical implications because they suggest that there are certain subsets of patients with certain types of GI cancers that cause metastases in certain regions of the spine.

RESUMO

Classic polyarteritis nodosa (PAN) is a vasculitis with systemic manifestations that is characterized by inflammatory and necrotizing lesions affecting medium and small muscular arteries, most frequently at the bifurcation of the vessels. These lesions lead to the formation of microaneurysms, hemorrhaging ruptured aneurysms, thrombosis, and, consequently, ischemia or organ infarction. Background and Objectives: We present a complex clinical case of a patient with a late diagnosis of polyarteritis nodosa with multiorgan involvement. Materials and Methods: The 44-year-old patient, in an urban environment, presented on her own in the emergency room for acute ischemia phenomena and forearm and right-hand compartment syndrome, requiring surgical decompression in the Plastic Surgery Clinic. Results: Significant inflammatory syndrome is noted, alongside severe normocytic hypochromic iron deficiency anemia, nitrogen retention syndrome, hyperkalemia, hepatic syndrome, and immunological disturbances: absence of cANCA, pANCA, anti Scl 70 Ac, antinuclear Ac, and anti dDNA Ac, as well as a low C3 fraction of the plasmatic complement system. The morphological aspect described in the right-hand skin biopsy correlated with the clinical data supports the diagnosis of PAN. Conclusions: The viral form of PAN seems to be individualized as a distinct entity, requiring early, aggressive medication.

RESUMO

BACKGROUND: COVID-19 is considered to be very contagious as it can be spread through multiple ways. Therefore, exposure risk of healthcare workers (HCWs) treating COVID-19 patients is a highly salient topic in exposure risk management. From a managerial perspective, wearing personal protective equipment and the risk of accidents occurring during aerosol generating procedures applied to COVID-19 patients are two interconnected issues encountered in all COVID-19 hospitals. OBJECTIVE: The study was conducted to understand the realistic impact of exposure risk management on HCWs exposed to risks of SARS-CoV-2 virus infection in a healthcare unit. In particular, this study discusses the role of personal protective equipment (PPEs) used in aerosol generating procedures (AGPs) to protect HCWs, and the related risk of accidents occurring when performing AGPs. METHODOLOGY: This is a cross-sectional single-hospital study conducted at the "Sf. Ioan cel Nou" Hospital in Suceava, Romania, that had to ensure safety of healthcare workers (HCWs) getting in contact with COVID-19 cases. Data used in the study were collected between 10.12.2020-19.03.2021 by means of a questionnaire that collected information on risk assessment and healthcare workers' exposure management, and which was translated and adapted from the World Health Organization (WHO) and applied to respondents online. For this purpose, ethical approval was obtained, doctors and nurses from all hospital departments being invited to complete the questionnaire. Data processing, as well as descriptive, correlation and regression analyses have been done by using the 21.0 version of the Statistical Package for Social Sciences software. RESULTS: Most of the 312 HCWs reported having always used disposable gloves (98.13%), medical masks N95 (or equivalent) (92.86%), visors or googles (91.19%), disposable coverall (91.25%) and footwear protection (95.00%) during AGPs. The waterproof apron had always been worn only by 40% of the respondents, and almost 30% of staff had not used it at all during AGPs. Over the last three months, the period when the questionnaire was completed, 28 accidents were reported while performing AGPs: 11 accidents with splashing of biological fluids/ respiratory secretions in the eyes, 11 with splashing of biological fluids/ respiratory secretions on the non-idemn skin, 3 with splashing of biological fluids/ respiratory secretions in the oral/ nasal mucosa and 3 with puncture/ sting with any material contaminated with biological fluids/ respiratory secretions. Also, 84.29% of respondents declared having changed their routine, at least, moderately due to COVID-19. CONCLUSION: An effective risk exposure management is based on wearing protective equipment. The only protection offered by the disposable coverall, as it results from our analysis, is related to splashing of biological fluids/ respiratory secretions on the non-idemn skin. In addition, the results show that the number of accidents should decrease due to the fact that disposable gloves and footwear protection are used while performing AGPs on patients with COVID-19 and hand hygiene is practised before and after touching a patient with COVID-19 (regardless of glove wearing).

RESUMO

BACKGROUND: The broad spectrum of diagnoses and clinical features of hand tumors and the absence of pathognomonic signs often lead to an inaccurate or delayed diagnosis. However, only a few reports have comprehensively referenced the diagnosis and clinical features of hand tumors. This study intends to highlight the clinical, imaging and histological characteristics of uncommon hand tumors or tumor-like lesions. METHODS: In this retrospective study, we report a series of 80 patients diagnosed with rare hand tumors and tumor-like lesions without skin damage. Age, gender, tumor location, imaging examinations and clinical and laboratory findings were analyzed. The histopathological exam established the final diagnosis. Surgery was indicated and performed in all cases. RESULTS: This study included: neurofibroma, glomus tumor, lipoma, schwannoma, epidermal inclusion cyst and idiopathic tenosynovitis with "rice bodies." We have described the clinical, imagistic and histopathological particularities of these tumors. Surgical management included the complete removal of tumors, with no recurrence recorded within two years and overall high patient satisfaction. The most common findings were lipomas and the rarest neurofibromas. CONCLUSIONS: To optimize the care of hand tumors and reduce diagnostic and treatment errors, knowledge of hand tumor types and their clinical and laboratory characteristics is necessary for every surgeon.

RESUMO

Background and Objectives: Diabetes mellitus (DM) is a complex disease affecting the whole metabolic balance of the body and resulting in multiple organ complications: cardiovascular, neuronal, renal, etc. Our study focuses on investigating the effect of zinc chloride (Zn) on certain blood parameters suggestive for assessing the metabolic disturbances, the liver and kidney function, the oxidative stress and the immune defense capacity in experimental-induced DM with streptozotocin (STZ) and cholesterol in rats. Materials and Methods: The animals were assigned to three groups, as follows: Group 1 (Control): buffer citrate solution 0.1 mL/100 g body; Group 2 (STZ): 20 mg/kg body STZ and fat diet (10 g cholesterol/100 g diet); Group 3 (STZ+Zn): 20 mg/kg body STZ + 5 mg/kg body Zn chloride and the same fat diet. DM was induced by administering STZ in a single take daily, for three consecutive days, Zn and citrate buffer were administered orally for a month. The protocol was approved by the Ethics Committee of the University 'Grigore T Popa' Iasi, in agreement with the International Regulations about the handling of laboratory animals. Results: The use of STZ in rats fed with cholesterol was correlated with important weight gain, hyperglycemia, the intensification of the transaminases activity and the increase in serum alkaline phosphatase, cholesterol, triglyceride, urea, creatinine and in malondialdehyde. Conclusions: The treatment with Zn resulted in weight loss and a decrease in blood sugar in diabetic rats. Supplementation with Zn notably reduced oxidative stress, preserved the pancreatic architecture and restored the liver and kidney function and structure in STZ-induced DM in rats.

RESUMO

BACKGROUND: Lipomas are the most frequent benign soft tissue tumor that are rarely found in the hand and are exceptionally rare on the fingers. The aim of this study was to investigate lipomas of atypical locations, so that they can be taken into account when making a differential diagnosis of a tumor of the hand or fingers. METHODS: We studied a group of 27 patients diagnosed with lipoma of the wrist, palm, and fingers. The diagnosis was made by clinical and imaging examinations. Surgical treatment was established based on symptoms of pain, paresthesias, functional impairment, or aesthetic concerns. Treatment outcomes were assessed clinically at 1.5 years post-intervention. RESULTS: Sizes over 5 cm were recorded in five cases, with the largest lipoma being 8 by 5 by 3.5 cm in size and weighing 125 g, located in the palm. There was one case of spontaneous tendon rupture and one case of carpal tunnel syndrome. There was no recurrence recorded at 1.5-year follow-up. CONCLUSIONS: Lipomas in the palm and fingers are rare entities (with more men affected), and surgical treatment consists of complete removal of the tumor and providing definitive healing. Despite their rarity, clinicians should consider lipomas when making differential diagnoses of soft tissue tumors of the hand.

RESUMO

(1) Background. We aimed to assess long-term efficacy and safety in inadequately controlled type 2 diabetes (T2DM) of two SGLT-2 inhibitors: empagliflozin (Empa) and dapagliflozin (Dapa), combined with metformin, other oral antidiabetics or insulin, according to the protocols in Romania. (2) Methods. The data of 100 patients treated for T2DM with associated dyslipidemia and/or cardiovascular diseases at the University Hospital and Consultmed Medical Center in Iasi were retrospectively reviewed (2017-2021). In total, 48 patients had received dapagliflozin (10 mg with oral antidiabetics or insulin) and 52 patients received empagliflozin (10 mg /25 mg with oral antidiabetics). (3) Results. In both groups, the lowering of BMI was significant: Dapa group (32.04 ± 4.49 vs. 31.40 ± 4.18 kg/m2; p = 0.006), and Empa group (34.16 ± 5.08 vs. 33.17 ± 4.99 kg/m2; p = 0.002). Blood sugar average levels decreased significantly (170 vs. 136 mg/dL; p = 0.001 for Dapa; 163 vs. 140 mg/dL; p = 0.002 for Empa) and also average levels of HbA1c (7.90% vs. 7.51%; p = 0,01 for Dapa; 7.72% vs. 7.35%; p = 0.004 for Empa). (4) Conclusions. Better results in all variables were observed in younger male patients with a shorter duration of diabetes and threshold BMI levels of 34.1, treated with SGLT2, and more significantly with Empa.

RESUMO

BACKGROUND: Although schwannoma (neurilemmoma) is the most common tumor of the peripheral nerve, its low incidence, slow growth and vague symptoms often lead to misdiagnosis or delayed diagnosis. The aim of the study is to present a series with a large number of schwannomas in the upper limbs, some with very rare occurrence. METHODS: We report 17 patients with a mean age of 58.5 years and upper limb schwannomas, located on the median, ulnar and radial nerves, but also on the posterior interosseous nerve and digital collateral nerves. The diagnosis was made by clinical examination and imaging tests, and in no case was a preoperative biopsy performed. Surgical treatment was established based on symptoms or aesthetic concerns. In all cases, a diagnosis of schwannoma was confirmed through histopathological and immunohistochemical examinations. RESULTS: For all patients, a complete tumor enucleation was performed under a surgical microscope. No recurrence was recorded at 2 years after surgery. Patient satisfaction was good, with complete socio-professional integration in all cases. CONCLUSIONS: Although more frequently present on the main nerve trunks, schwannoma may be present on the collateral digital nerves in rare cases. A correct technique with complete tumor excision offers excellent postoperative outcomes and avoids recurrences.

RESUMO

PURPOSE: Glomus tumors account for 1-4% of benign hand tumors. In 65% of cases, it is located in the nail bed. Its rarity makes misdiagnosis problems relatively common. Symptomatology is characterized by the hallmark symptomatic triad. Imaging investigations may guide the diagnosis, but the diagnosis is made by pathological examination doubled by immunohistochemical (IHC) markers. PATIENTS, MATERIALS AND METHODS: We studied a group of seven female patients, aged 28 to 56 years. Clinical examination revealed the presence of the characteristic symptomatic triad. Ultrasound imaging tests were performed. RESULTS: Anatomopathological examination made a diagnosis of glomus tumor in all seven cases. IHC staining showed that tumor cells were positive for alpha-smooth muscle actin (α-SMA) and h-caldesmon in all seven cases and negative for cluster of differentiation 34 (CD34) in 72.14%. IHC stainings for p63, S100, cytokeratin (CK) AE1∕AE3 were negative in all cases. The clinical diagnosis completed by ultrasonography was histopathologically confirmed in all cases. CONCLUSIONS: Although the glomus tumor is a rare lesion, we need to be familiar with it because a diagnostic delay also implies a treatment delay which will lead to amplified suffering and even real disability due to the high-intensity pain in these cases.

RESUMO

ABSTRACT: Injuries that result in thumb amputation cause a loss of 50% of hand function. Microsurgical replantation remains the gold standard of thumb reconstruction techniques. The non-microsurgical technical variants of thumb reconstruction described so far aim to create a neo-thumb of adequate length, stable, opposable, sensitive, and last but not least esthetically pleasing appearance. Avulsion of the distal phalanx and the absence of the nail will determine a functional deficit but also an unesthetic appearance. When replantation is not possible or the patient refuses to "sacrifice" another anatomical region for thumb reconstruction, the "reposition-flap" technique can be used. Although often controversial, this surgical technique deserves proper attention and should be used in some cases. We studied a group of 32 patients with distal thumb amputations. In patients with amputations in zone II according to Tamai, with interphalangeal joint preservation, the thumb was reconstructed using "reposition-flap" with an O'Brien flap in 15 cases. In the remaining 17 cases where the amputation was at the level of the interphalangeal joint, we used the same technique, but the thumb neopulp was reconstructed with the Littler heterodigital neurovascular flap harvested from the ulnar border of the middle finger in 11 cases or radial border of the ring finger in 6 cases. The results were evaluated from a functional (Kapandji score), sensitive (2-point discrimination, Semmes-Weinstein test) but also esthetically (patient satisfaction) point of view. Donor site morbidity, cold intolerance, the presence of nail dystrophy, and bone resorbtion were also assessed. The disabilities of the arm, shoulder and hand score was evaluated for each patient. Although various surgical and microsurgical techniques for thumb reconstruction are described, when choosing the technique to use we must first consider patient's wishes. A well-informed patient will be able to make, with the surgeon, the best decision for him concerning the reconstruction option.

RESUMO

BACKGROUND: Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice. We propose the association of microsurgical techniques with some modification (modified Baudet technique) to obtain higher survival rate of the reimplanted stump. METHODS: This study included cases of 3 male patients with total ear amputation, the injuries and their mechanism (workplace accident) being identical. Chief complaints were pain, bleeding, important emotional impact due by an unaesthetic appearance. The established diagnosis was traumatic complete ear amputation (grade IV auricular injury according to Weerda classification). Microsurgical replantation was performed only with arteriorraphy, and no vein anastomosis. Cartilage incisions and skin excisions were made to enlarge the cartilage-recipient site contact area. Medicinal leeches were used to treat venous congestion, to which systemic anticoagulant therapy was added. RESULTS: The results showed the survival of the entire replanted segment in all cases, with good function and esthetical appearance. Patients were fully satisfied with the final outcome. CONCLUSION: Microsurgical replantation is the gold standard, for the surgical treatment of total ear amputation. We believe that cartilage incisions and the increased surface of contact between cartilage and recipient site has an adjuvant role in revascularization of the amputated stump (with only arterial anastomosis) and the use of hirudotherapy helps to relieve early venous congestion.

RESUMO

The World Health Organization recommends that "palliative care should be integrated as a routine element of all Undergraduate Medical Education." However, the provision of training for medical undergraduates is variable; only 18% of 51 European countries have mandatory training in palliative medicine. EDUPALL is an ERASMUS+ funded international collaborative project to develop and pilot an undergraduate program for training in palliative medicine. The objective of this study was to critically review and revise current European Association for Palliative Care (EAPC) Recommendations for the Development of Undergraduate Curricula in Palliative Medicine and translating these into an updated curriculum document. Clinicians, academics, and researchers from Romania, Ireland, Germany, Austria, Spain, and the United Kingdom reviewed the EAPC recommendations using a variant of consensus methodology, Nominal Group Technique. From the updated document, four working-groups translated each recommendation into a specific learning objective, and developed associated learning outcomes, stratified by domain: attitude, cognition, and skills. The outcomes and objectives were organized into discrete teaching units and transferred into a curriculum template, identifying notional hours, teaching, and assessment strategies. To ensure quality control, the draft template was circulated to experts from 17 European countries, together with a brief survey instrument, for peer review purposes. All 17 reviewers returned overwhelmingly positive comments. There was large agreement that: the teaching units were logically organized; learning outcomes covered core training needs; learning objectives provided guidance for teaching sessions; learning modalities were appropriately aligned; and assessment strategies were fit for purpose. An updated and standardized curriculum was developed, which provides a platform for the sequential development of the next phases of the EDUPALL project.

RESUMO

RATIONALE: Nail bed solitary neurofibroma is an extremely rare tumor, with only 9 cases recorded in the literature so far. PATIENT CONCERN: We present the case of a 42-year-old female patient, with a history of a slowly growing tumor in the nail bed of the left index and no clinical features of type I neurofibromatosis. DIAGNOSIS: Nail bed solitary neurofibroma. INTERVENTION: The tumor was surgically removed and the pathology examination established the diagnosis of neurofibroma. OUTCOMES: The postoperative outcome was good, with no recurrence 12 months after surgery. LESSONS: We present the rarity of this type of tumor localized in the nail bed, taking into consideration the only 9 cases recorded in the literature. Nail bed solitary neurofibroma should be also included in the differential diagnosis of a nail bed tumor.

RESUMO

Antidepressant medication influences cellular lipogenesis, being associated with metabolic side effects including weight gain. Due to the increasing use of antidepressants in children and adolescents, their metabolic and endocrine adverse effects are of particular concern, especially within this pediatric population that appears to be at greater risk. Genetic factors with a possible influence on antidepressant's adverse effects include CYP [cytochrome P450 (CYP450)] polymorphisms. We target to evaluate the efficacy of the pharmacogenetic testing, when prescribing antidepressants, in correlation with the occurrence of adverse events and weight gain. Our research was performed between the years 2010 and 2016, in the University Clinic of Child and Adolescent Psychiatry, Timisoara, Romania. We recruited 80 patients, children and adolescents with depressive disorders. Our study sample was divided in two groups: G1 - 40 patients took treatment after pharmacogenetic testing, and G2 - 40 patients without pharmacogenetic testing before the treatment election. Our results show statistically significant differences concerning the weight gain for groups G1 (with pharmacogenetic testing) and G2 (without pharmacogenetic testing). The CYP genotype and the pharmacogenetic testing, for choosing the personalized antidepressant therapy in children and adolescents with depressive disorders, proved to be good predictors for the response to antidepressants and the side effects registered, especially for weight gain. The significant correlations between the CYP polymorphisms for group G2 (without pharmacogenetic testing) and the weight gain/body mass index (BMI) increase, as major side effects induced by antidepressants, proved the fact that the pharmacogenetic screening is needed in the future clinical practice, allowing for individualized, tailored treatment, especially for at-risk pediatric categories.

RESUMO

Ki-67 parameter is a proliferation marker in malignant tumors. The increased proliferation activity and the decreased prognosis in lung cancer determined us to investigate different parameters connected to the tumor's aggression, such as cellularity, Ki-67 positivity rate, and proliferating cell nuclear antigen (PCNA). We evaluated the proliferative activity in 62 primary lung tumors by determining the cell's percentage of Ki-67 and immunoreactive PCNA (using MIB-1 and PCNA monoclonal antibodies), classifying Ki-67 and PCNA immunoreactivity into three score groups. The results obtained emphasized a linkage between Ki-67 score with the histological tumor subtype, tumor cellularity and degree of differentiation and with other proliferation immunohistochemistry (IHC) markers, such as p53 cellular tumor antigen. The tumor's cellularity, the Ki-67 positivity rate and PCNA, together with the clinical stage and the histological differentiation bring extra pieces of useful information in order to anticipate the evolution and the prognosis of lung cancer.

RESUMO

Helicobacter pylori (H. pylori) is the etiological factor for gastritis in more than half of the worldwide population. H. pylori infection increases the risk for gastric pathology, but could also have consequences on cardio-metabolic status. Obesity has as epidemic growth, and the only efficient long-term treatment for morbidly obese patients is currently surgery. Although of vital importance, the preoperative assessment is not standardized, including the aspects related to H. pylori infection. The aim of this prospective study was to evaluate the prevalence of H. pylori (Hp) infection in a group of patients referred to bariatric surgery and the agreement of two commonly used methods for its diagnosis. We included 70 asymptomatic obese patients consecutively for 14 months, who were evaluated by serology (anti-Hp IgG antibodies) and by histology (gastroscopy with gastric mucosa biopsy). If diagnosed, H. pylori infection was standard treated and afterwards, all patients underwent laparoscopic sleeve gastrectomy; the resected stomach was morphologically evaluated. 58.6% of patients were H. pylori positive on serology and 51.4% were H. pylori positive on histology, agreement coefficient factor kappa between the two methods being 0.686, p<0.001. The serological diagnosis had a sensibility of 90.3% and a specificity of 77.8%. The prevalence of H. pylori infection in the resected stomach was 11.4%, and was associated with more severe degrees of chronic gastritis. In conclusion, as gastroscopy should anyhow be performed in all patients referred to surgery, our data favor the histological evaluation in all patients and the eradication treatment according to its results.
