RESUMO

Atrial fibrillation (AF) and diabetes mellitus (DM) constitute two major closely inter-related chronic cardiovascular disorders whose concurrent prevalence rates are steadily increasing. Although, the pathogenic mechanisms behind the AF and DM comorbidity are still vague, it is now clear that DM precipitates AF occurrence. DM also affects the clinical course of established AF; it is associated with significant increase in the incidence of stroke, AF recurrence, and cardiovascular mortality. The impact of DM on AF management and prognosis has been adequately investigated. However, evidence on the relative impact of glycemic control using glycated hemoglobin levels is scarce. This review assesses up-to-date literature on the association between DM and AF. It also highlights the usefulness of glycated hemoglobin measurement for the prediction of AF and AF-related adverse events. Additionally, this review evaluates current anti-hyperglycemic treatment in the context of AF, and discusses AF-related decision-making in comorbid DM. Finally, it quotes significant remaining questions and sets some future strategies with the potential to effectively deal with this prevalent comorbidity.

RESUMO

OBJECTIVE: The purpose of this study is to identify clinical manifestations of eating disorders in the Eastern Mediterranean region from the first century AD until the seventh century AD and evaluate relevant awareness among the physicians of the era. METHOD: The authors searched original medical texts written in Greek by physicians practicing in the Eastern Mediterranean region from the first century AD to the seventh century AD. The search focused on passages that include possible references to clinical entities analogous to anorexia nervosa (AN) and bulimia nervosa (BN) as described in the DSM-5 and the contemporary literature. RESULTS: Descriptions of conditions that resemble AN or BN can be found in the work of Galen, Oribasius, Aetius of Amida, Leon Philoumenos, Alexander Trallian, and Paul of Egina. Successive physicians confirmed the observations of their predecessors and add to the description of the clinical presentations and their etiology. DISCUSSION: This research provides evidence of awareness of presentations resembling currently defined eating disorders in the Eastern Mediterranean region during a period with different norms and values. Observations from the period can serve as a point for reflection about the characteristics and etiology of AN and BN in the 21st century.

RESUMO

BACKGROUND: A relationship between obesity and adverse outcomes in patients with post-sternotomy wounds undergoing pedicle flap reconstruction is not well-documented. In this study, we present a single-centre retrospective case series analysis of early postoperative outcomes of patients with infected post-sternotomy wounds undergoing pedicle flap reconstruction. We also propose a management algorithm for such patients, based on BMI and wound width. METHODS: We retrospectively analyzed all patients, who underwent pedicle flap reconstruction for major sternal wound infections after sternotomy for cardiac surgery in a tertiary hospital in Germany during a 5-year period. Exclusion criteria included patients younger than 18 years of age and patients with BMI < 18.5 kg/m2. Patients were divided into 2 groups according to BMI: normal-weight (NW; BMI < 25 kg/m2) and overweight/obese (OB/OW; BMI > 25 kg/m2). Both groups were compared in terms of preoperative parameters and early postoperative outcomes. Preoperative parameters included demographics, wound bacteria and comorbidities. Postoperative outcomes included duration of surgery time (from incision to skin closure), transfusion requirement (during surgery and entire hospital stay), onset of flap and donor-site complications, length of stay and 30-day mortality. We employed the two-tailed t-test to compare continuous variables and the two-sided Fischer's exact test to compare categorical variables. Statistical significance was set at p < 0.05. RESULTS: The total sample consisted of 48 patients. Overall mean BMI was 28.4 (6.1) kg/m2. Mean age was 67 (12) years. The study group consisted of 28 patients with BMI > 25 kg/m2, who were compared with 20 normal-weight patients. There was a significant difference amongst both groups regarding duration of surgery (120 vs. 174 min, p < 0.05). Donor-site complications requiring intervention were observed in 30% of patients in both groups. Flap-related complications were recorded in 16 (57%) cases in the study group and 7 cases in the control group (35%, p = 0.15). CONCLUSIONS: We conclude that wound width and BMI can aid the decision-making process for patients with infected sternal wounds after cardiac surgery requiring pedicle flap reconstruction. However, in our case series analysis, OB/OW patients were not found to be at statistically significantly increased risk for worse postoperative outcomes, but were associated with a longer duration of surgery.

RESUMO

BACKGROUND: Several loco-regional flaps have been described for plantar forefoot coverage. We, herein, report our single-centre experience in plantar forefoot reconstruction and propose a decision-making process based on the defect's size. METHODS: This is a retrospective case series study of all patients who underwent plantar forefoot reconstruction in a 10-year period. We propose a treatment algorithm, based on the defect size. Defects are classified into small, moderate and large. Small defects (<10cm2) can be covered with the hemi-pulp toe flap. Patients with moderate defects (10-25cm2) can be treated with the reverse medial plantar artery flap (MPAF) from the instep area. For large defects (>25cm2), we recommend regional flaps, that is the distally based sural flap (DBSF) from the ipsilateral calf, or free flaps, such as the anterolateral thigh flap (ALT) or the skin-grafted gracilis flap. RESULTS: The data of 51 patients were collected and analysed. The median age was 58 years (range 19-84). Nine patients had small defects and underwent hemi-pulp toe flap reconstruction. Three patients presented with moderate defects that were covered with reverse MPFs. The vast majority of the patients (39 patients) had large defects. Of these, eight cases were treated with DBSF and 31 cases with free flaps. Free flap transfers were successful in 97% of the cases. Overall complication rate was 25%. CONCLUSION: We conclude that local flaps should be preferred in plantar forefoot reconstruction as they provide like-tissue for small to moderate defects, for large defects regional flaps or free flaps were indicated. A defect-based approach can facilitate the decision-making process.

RESUMO

Cardiovascular disease is the predominant cause of death in type 2 diabetes mellitus (T2DM). Evidence suggests a strong association between duration and degree of hyperglycemia and vascular disease. However, large trials failed to show cardiovascular benefit after intensive glycemic control, especially in patients with longer diabetes duration. Atherosclerosis is a chronic and progressive disease, with a long asymptomatic phase. Subclinical atherosclerosis, which is impaired in T2DM, includes impaired vasodilation, increased coronary artery calcification (CAC), carotid intima media thickness, arterial stiffness, and reduced arterial elasticity. Each of these alterations is represented by a marker of subclinical atherosclerosis, offering a cost-effective alternative compared to classic cardiac imaging. Their additional use on top of traditional risk assessment strengthens the predictive risk for developing coronary artery disease (CAD). We, herein, review the existing literature on the effect of glycemic control on each of these markers separately. Effective glycemic control, especially in earlier stages of the disease, attenuates progression of structural markers like intima-media thickness and CAC. Functional markers are improved after use of newer anti-diabetic agents, such as incretin-based treatments or sodium-glucose co-transporter-2 inhibitors, especially in T2DM patients with shorter disease duration. Larger prospective trials are needed to enhance causal inferences of glycemic control on clinical endpoints of CAD.

RESUMO

The aim of this study was to assess the factors associated with impaired vascular function in patients with poorly controlled type 2 diabetes (DM2) with and without overt cardiovascular disease (CVD). Ninety-five patients with DM2 and poor glycemic control were recruited and divided into two groups: Group 1, with known CVD (n = 38), and Group 2, without CVD (n = 57). Patients in Group 2 were further subdivided into those with short (<5 years, group 2b) and long (>5 years, group 2a) diabetes duration. Subclinical markers of atherosclerosis were assessed. Glycemic control was similar in the two groups (HbA1c: 9.2% (1.5) vs. 9.4% (1.8), p = 0.44). In Group 1, lower FMD (3.13 (2.16)% vs. 4.7 (3.4)%, p < 0.05) and higher cIMT (1.09 (0.3) mm vs. 0.96 (0.2) mm, p < 0.05) was seen compared with Group 2, whereas PWV was similar (12.1 (3.4) vs. 11.3 (3.0) m/s, p = 0.10). Patients in Group 2b had significantly lower PWV and cIMT and higher FMD compared to Group 1 (p < 0.05). Among patients with poorly controlled T2D, more pronounced vascular dysfunction was present in those with overt macrovascular disease. In patients with T2D without known CVD, vascular dysfunction was associated with disease duration. The use of vascular indices for cardiovascular risk stratification in patients with T2D requires further study.

RESUMO

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder of the follicular epithelium. The aim of the study was to investigate the effectiveness of colchicine on the clinical outcomes of HS patients, and to evaluate wither colchicine as monotherapy or in combination with doxycycline would provide better outcomes. Methods: A retrospective study was conducted including 44 patients with established HS, divided into three groups. The first group (n = 15 patients) received colchicine as monotherapy, the second group (n = 14 patients) received colchicine and doxycycline 100 mg/d, while the third group (n = 15 patients) received colchicine and doxycycline 40 mg/d. Disease severity during treatment was assessed at baseline and follow-up, using the Hurley Scoring System and the International Hidradenitis Suppurativa Severity Score System (IHS4). All patients were also asked to complete a Dermatology Life Quality Index (DLQI) questionnaire. These scores were compared among the study groups. Results: The DLQI and IHS4 scores significantly improved after treatment with colchicine (p < 0.001) in all groups. All colchicine regimes, including the single colchicine regime, colchicine plus doxycycline 100 mg regime, and colchicine plus doxycycline 40 mg regime, resulted in significant improvements in the DLQI and IHS4 scores (p < 0.001). Clinical improvement based on DLQI and IHS4 scores was similar in all groups. None of the patients had to discontinue the treatment due to adverse events. Discussion: In conclusion, our findings suggest that colchicine may improve clinical severity and quality of life in HS patients, either as monotherapy or in combination with doxycycline, both at antimicrobial (100 mg) and sub-antimicrobial (40 mg) doses.

RESUMO

PURPOSE: The aim of the present study was to investigate the effect of intensive antidiabetic therapy on vascular indices in type 2 diabetes mellitus (T2DM) patients. METHODS: Poorly controlled T2DM patients (n = 62, mean age 64 years, T2DM duration 14 years, HbA1c ≥ 7.5%) were studied at baseline and following intensive treatment to achieve optimal glycemic control. Brachial artery flow-mediated dilation, carotid-femoral pulse wave velocity, central augmentation index, large and small (C2) artery compliance, carotid intima-media thickness (cIMT), and ankle-brachial index were assessed at baseline and follow-up. RESULTS: HbA1c decreased from 8.8% (8.1, 10.1) (median, interquartile range-IQ) to 7.4% (6.9, 7.8), p < 0.001. Triglycerides and high-sensitivity C-reactive protein levels were decreased by ~ 10% and 50%, respectively (p < 0.05). Maximum cIMT and C2 increased at follow-up (0.97 ± 0.25 to 1.03 ± 0.27 mm and 3.3 (2.7, 4.2) to 4.2 (3.2, 5.4) ml/mmHg × 10, respectively, p < 0.05). In subgroup analysis, the observed changes in vascular indices were not affected by diabetes duration, presence of cardiovascular disease, or insulin treatment. CONCLUSION: In patients with long-standing T2DM, short-term aggressive glycemic control was associated with an improvement of microvascular function (C2) and deterioration of carotid atherosclerosis (IMT) without any effect on the elastic properties of large arteries.

RESUMO

BACKGROUND: Nivolumab is an anti-programmed cell death protein 1 antibody, typically used as cancer immunotherapy agent. Despite multiple clinical benefits it might cause autoimmune-related side-effects, often involving the endocrine system. To our knowledge, this is the first case of nivolumab-induced hypophysitis manifesting several months after treatment discontinuation. CASE PRESENTATION: We, herein, report a 53-year-old patient with hypophysitis and isolated adrenocorticotropic hormone deficiency, who presented with recurring syncopal episodes and persistent mild hyponatremia. The performed challenged tests were consistent with secondary adrenal insufficiency, while responses of other anterior pituitary hormones were preserved. Magnetic resonance imaging revealed thickened pituitary stalk, consistent with hypophysitis. The patient's condition gradually improved after administration of hydrocortisone, with normalization of sodium and glucose-levels. The related literature is discussed. CONCLUSIONS: We conclude that even after discontinuation of nivolumab, isolated adrenal insufficiency can occur. Therefore, in case of administration of such agents, clinical assessment, and routine monitoring of blood pressure, sodium-, glucose-levels, pituitary hormones as well as magnetic resonance imaging are needed to identify such conditions and prevent an adrenal crisis.

RESUMO

OBJECTIVE: We describe a one-stage surgical technique for the management of recurrent cervical stitch sinus after thyroidectomy. METHOD: A retrospective, single-centre study of all patients who were operated on because of cervical neck sinus after thyroidectomy. We provide a detailed description of our surgical approach, based on guided sinus removal after prior tract staining with methylene blue and subsequent obliteration using local strap muscle flap. RESULTS: A total of seven patients with a mean age of 46 years were included in the study. All patients had a past history of thyroidectomy because of goitre (n=5) or thyroid cancer (n=2) which had previously been unsuccessfully debrided two or three times. Surgical sinus removal was successful in all cases and no recurrence was observed during the follow-up time. CONCLUSIONS: We conclude that a comprehensive en bloc resection down to the suture granuloma is essential in order to provide surgical cure and prevent recurrence.

RESUMO

Acute acalculous cholecystitis (AAC) is an inflammation of the gallbladder not associated with the presence of gallstones. It usually occurs in critically ill patients but it has also been implicated as a cause of cholecystitis in previously healthy individuals. In this subgroup of patients, infectious causes comprise the primary etiology. We, herein, discuss the pathophysiological mechanisms involved in AAC, focusing on the infectious causes. AAC associated with critical medical conditions is caused by bile stasis and gallbladder ischemia. Several mechanisms are reported to be involved in AAC in patients without underlying critical illness including direct invasion of the gallbladder epithelial cells, gallbladder vasculitis, obstruction of the biliary tree, and sequestration. We emphasize that multiple pathogenic mechanisms may concurrently contribute to the development of AAC in varying degrees. Awareness of the implicated pathogens is essential since it will allow a more focused examination of the histopathological specimens. In conclusion, additional research and a high degree of clinical suspicion are needed to clarify the complex spectrum of mechanisms that are involved in the pathogenesis of AAC.

RESUMO

BACKGROUND Invasive fungal infections (IFI) are major risks for mortality after liver transplantation (LT). The aim of this study was to evaluate possible risk factors for the development of IFI after LT. MATERIAL AND METHODS All adult patients with IFI after LT between January 2012 and December 2016 at Essen University were identified. Pre-, intra-, and postoperative data were reviewed. These were compared to a 1-to-3 matched control group. Multinominal univariate and multivariate regression analyses were performed. RESULTS Out of the 579 adults who underwent LT, 33 (5.6%) developed postoperative IFI. Fourteen had invasive aspergillosis with 7 (50%) mortality, and 19 had Candida sepsis with 7 (37%) mortality. The overall mortality due to invasive fungal infections was 42%. Perfusion fluid contamination with yeast was detected in 5 patients (15%). Multivariate regression analyses showed that preoperative dialysis (OR=1.163; CI: 1.038-1.302), Eurotransplant donor risk index (OR=0.04; CI=0.003-0.519), length of hospital stay (OR=25.074; CI: 23.99-26.208), and yeast contamination of the preservation fluid (OR=47.8; CI: 4.77-478, 96) were associated with IFI in the Candida group, whereas duration of surgery (OR=1.013; CI: 1.005-1.022), ventilation hours (OR=0.993; CI=0.986-0.999), and days of postoperative dialysis (OR=1.195; CI: 1.048-1,362) were associated with IFI in the aspergillosis group. CONCLUSIONS Post-LT IFI had 42% mortality in our cohort. Prophylactic antifungal therapy should be expanded to broader risk groups as defined above.

RESUMO

Wound irrigation (i.e. washing out a wound before wound closure) aims to reduce the microbial burden by removing tissue debris, metabolic waste, and tissue exudate from the surgical field before site closure. Although it is a popular procedure in every day surgical practice, the lack of procedure standardization, leads to studies with high heterogeneity and often controversial results. Thus, there are studies that advocate its use, while others discourage its implementation in clinical practice to reduce the risk of surgical site infection. The present article reviews the current literature on wound irrigation for preventing surgical site infections. Several irrigants are presented. Chlorexidine is generally considered to be less effective than povidone-iodine, while antibiotics are not that common nowadays, as they require prolonged exposure with the target to act. Hydrogen peroxide has several potential complications, which eliminate its use. Any differences in the incidence of surgical site infections between different irrigants, especially between antibacterial and non-bacterial ones, should be viewed sceptically. More randomized controlled studies are needed to provide better quality of evidence regarding the irrigants' effectiveness and safety.

RESUMO

INTRODUCTION: Eccrine and apocrine hidrocystomas are uncommon, benign, cystic proliferations of the sweat glands usually located on the head and neck area. OBJECTIVES: To describe the key clinical and histopathological characteristics of a large series of hidrocystomas in Greece to improve diagnostic accuracy, and to perform a historical review of the medical term hidrocystoma. METHODS: A case series of 22 hidrocystomas from 20 consecutive patients treated with surgery at University Hospital of Heraklion in Crete, Greece, from January 1, 1998 to January 1, 2020 was performed along with a comprehensive historical literature review of the term hidrocystoma and its corresponding term hydatis from ancient Greek literature to the present. Data were obtained from medical records. All patients had a histopathologically confirmed diagnosis of hidrocystoma. Formalin-fixed paraffin-embedded (FFPE) sections of 22 tumors of the 20 consecutive patients were retrieved from the pathology laboratory archive and stained for SMA, p63, and GCDFP-15 with immunochemistry and periodic acid-Schiff (PAS) histochemical stain. RESULTS: Overall, 22 hidrocystomas (11 apocrine and 11 eccrine hidrocystomas) surgically excised from 20 patients were included in this study. Of the 20 patients, 10 (50%) were male and 10 (50%) were female, with a mean age of 56 ± 15 years. Hidrocystomas commonly occurred on the eyelids (73%), inner canthus (9%), eyebrow (4.5%), neck (4.5%), nose (4.5%), and ear (4.5%). All apocrine hidrocystomas stained positive for SMA, GCDFP-15, CAM 5.2, PAS, and PAS-D. No recurrence was observed. CONCLUSIONS: Here we have presented the clinicopathological characteristics of the largest case series of hidrocystomas in Europe and the Mediterranean region. Only apocrine hidrocystomas stained positive for SMA, GCDFP-15, CAM 5.2, PAS, and PAS-D.

RESUMO

OBJECTIVE: Computerized clinical image analysis is shown to improve diagnostic accuracy for cutaneous melanoma but its effectiveness in preoperative assessment of melanoma thickness has not been studied. The aim of this study, is to explore how melanoma thickness correlates with computer-assisted objectively obtained color and geometric variables. All patients diagnosed with cutaneous melanoma with available clinical images prior to tumor excision were included in the study. All images underwent digital processing with an automated non-commercial software. The software provided measurements for geometrical variables, i.e., overall lesion surface, maximum diameter, perimeter, circularity, eccentricity, mean radius, as well as for color variables, i.e., range, standard deviation, coefficient of variation and skewness in the red, green, and blue color space. RESULTS: One hundred fifty-six lesions were included in the final analysis. The mean tumor thickness was 1.84 mm (range 0.2-25). Melanoma thickness was strongly correlated with overall surface area, maximum diameter, perimeter and mean lesion radius. Thickness was moderately correlated with eccentricity, green color and blue color. We conclude that geometrical and color parameters, as objectively extracted by computer-aided clinical image processing, may correlate with tumor thickness in patients with cutaneous melanoma. However, these correlations are not strong enough to reliably predict tumor thickness.
