Abstract
PURPOSE OF REVIEW To review current literature examining the presence of subclinical micro- and macrovascular alterations in normotensive individuals and their clinical significance in terms of hypertension prediction. Emphasis is placed on alterations that can be detected in peripheral vascular beds using non-invasive, easily applicable methodology, as these are in general easier to capture and evaluate in clinical practice compared to more complex invasive or functional tests. RECENT FINDINGS Arterial stiffness, increased carotid intima-media thickness, and altered retinal microvascular diameters predict the progression from the normotensive to the hypertensive state. By contrast, there is substantial lack of relevant prospective studies for skin microvascular alterations. Although conclusions regarding causality cannot be safely deduced from available studies, detection of morphological and functional vascular alterations in normotensive individuals emerges as a sensitive indicator of progression to hypertension and hence increased CVD risk. An increasing amount of evidence suggests that early detection of subclinical micro- and macrovascular alterations would be clinically useful for the early identification of individuals at high risk for future hypertension onset. Methodological issues and gaps in knowledge need to be addressed before detection of such changes could guide the development of strategies to prevent new-onset hypertension in normotensive individuals.

ASSESSING SKIN MICROCIRCULATION IN PATIENTS AT CARDIOVASCULAR RISK BY USING LASER SPECKLE CONTRAST IMAGING. A NARRATIVE REVIEW. Clin Physiol Funct Imaging 2023. [PMID: 37020404 DOI: 10.1111/cpf.12819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 02/15/2023] [Accepted: 03/27/2023] [Indexed: 04/07/2023]
Abstract
Skin tissue holds a prominent role in microcirculatory research as an easily accessible vascular bed for the non-invasive evaluation of microvascular function. Skin microvascular changes have been associated to alterations in distinct target organs and vascular beds, reinforcing the hypothesis that skin microcirculation can be used as a model of generalized microvascular function. In addition, skin microvascular dysfunction has been documented in cardiovascular disease and patients of increased cardiovascular risk where it has been associated with multiple cardiovascular risk factors, rendering it a candidate surrogate marker of vascular damage. Laser Speckle Contrast Imaging (LSCI) is a non-invasive, dynamic laser technique that allows assessment of skin microvascular function (SMF) by obtaining two-dimensional maps of the skin perfusion in real time with high spatial and temporal resolution and, most importantly, with the highest reproducibility as compared to other laser methods. An ever-increasing number of studies using LSCI is confirming evidence of impaired SMF in several cardiovascular risk groups, therefore expanding its application in microvascular research and showing its potential clinical utility. This review attempts to present the growing importance of SMF in cardiovascular research and the emergence of LSCI technique as a robust imaging modality with a promising role to explore skin microvascular physiology. After a short description of the relevant technique and its main principle of function, we have also opted to present the most up to date studies using LSCI for the investigation of SMF in patients with cardiovascular disease as well as various groups of increased cardiovascular risk.

Abstract
Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease affecting multiple organs, including the central nervous system. Subclinical brain lesions have been reported in SLE patients, even without overt neuropsychiatric manifestations (non-NPSLE). Studies using PET/MRI, examining structural or functional brain abnormalities in SLE, have been previously performed, either at rest or during a mental task (1–3). Exercise can be used to identify early alterations in brain oxygenation that might not detectable during resting conditions (4).Objectives:Our study aimed to examine possible differences in cerebral oxygenation during a handgrip exercise test between SLE patients without neuropsychiatric manifestations and age-matched controls.Methods:Fifty-two participants (26 non-NPSLE and 26 controls), following evaluation of handgrip strength, underwent a protocol involving a seated rest (baseline), a 3-min handgrip exercise (at 30% of maximal strength), and a 3-min recovery. Continuous-near-infrared-spectroscopy (NIRS) was used to monitor changes in cerebral-oxygenated hemoglobin (O2Hb), de-oxygenated (HHb) and total-hemoglobin (tHb). Beat-by-beat blood pressure (Finapres) was continuously monitored.Results:There were no differences between the two groups in age, body mass index, blood pressure, and smoking status. Median SLE duration was 7.5 (3.0 – 16.0) years. During exercise, cerebral -O2Hb increased in both groups; however, non-NPSLE exhibited a significantly lower increase in O2Hb vs. controls (average response:1.20±0.89 vs. 2.33±1.61μM, respectively, p<0.005) and lower tHb responses (p<0.05), with no differences in HHb.Conclusion:Our data show, for the first time, that SLE patients even without overt neuropsychiatric manifestations exhibit a blunted increase in cerebral-O2Hb during a submaximal exercise stimulus compared to age-matched controls. Examining brain oxygenation during a simple exercise task may assist in identifying patients with early alterations in cerebral function.References:[1]Mak A, Ren T, Fu EH yun, Cheak AA cia, Ho RCM.

Abstract
Microvesicles (MVs) have recently emerged as markers of thrombosis. Furthermore, there is an unexplained residual thrombotic risk is observed in patients with acute coronary syndrome (ACS) and/or stable coronary artery disease (CAD), despite treatment. We measured platelet (PMVs) and erythrocyte (ErMVs) in patients with ACS and stable CAD, both in the peripheral and coronary circulation. We studied consecutive eligible patients during a coronary angiography. Blood samples were collected from the stem of the left coronary artery and femoral artery. PMVs were significantly increased in CAD patients compared to controls. ACS patients had also increased PMVs in coronary and peripheral circulation, compared to controls. Furthermore, ACS patients exhibited increased PMVs in coronary compared to peripheral circulation. Lastly, coronary PMVs were associated with the severity of CAD based on the SYNTAX score. No significant differences were observed in the levels of ErMVs among groups. Therefore, PMVs emerge as novel markers of thrombosis in CAD, further augmenting the vicious cycle of inflammation and thrombosis during ACS. Importantly, coronary PMVs may reflect the severity of CAD in this population.

Abstract
This report presents a case of extensive tophaceous pseudogout involving the temporomandibular joint (TMJ), causing erosion into the middle cranial fossa. Pseudogout is a benign metabolic arthropathy caused by calcium pyrophosphate dihydrate crystal deposition within joints and peri-articular tissue. Pseudogout more frequently occurs in large joints such as the knee, wrist, symphysis pubis, and shoulder. Tophaceous pseudogout involving the TMJ is rare, with only seven cases involving erosion into the middle cranial fossa reported previously. Despite skull base erosion being a rare consequence of this erosive disease, this case highlights the importance of appropriate investigation and multidisciplinary team management.

Abstract
Background This experimental study examined the effect of the antioxidant drug "U-74389G", on a rat model and particularly in a hypoxia - reoxygenation protocol. The effects of that molecule were studied hematologically using blood mean platelets volume (MPV) levels. Methods 40 rats of mean weight 231.875 g were used in the study. MPV levels were measured at 60 min of reoxygenation (groups A and C) and at 120 min of reoxygenation (groups B and D). The drug U-74389G was administered only in groups C and D. Results U-74389G administration kept significantly increased the predicted MPV levels by 12.77 ± 3.07% (p = 0.0001). Reoxygenation time non-significantly decreased the predicted MPV levels by 2.55 ± 3.71% (p = 0.4103). However, U-74389G administration and reoxygenation time together kept significantly increased the predicted MPV levels by 7.09 ± 1.91% (p = 0.0005). Conclusions U-74389G administration whether it interacted or not with reoxygenation time kept significantly increased the predicted MPV levels. This finding has great clinical interest in blood clotting and coagulation pathophysiology.

Abstract
Summary
This experimental study examined the effect of the antioxidant drug U-74389G on a rat model and particularly in a liver ischemia - reperfusion protocol. The effects of that molecule were studied biochemically using blood mean albumin levels. 40 rats of mean weight 231.875 g were used in the study. Albumin levels were measured at 60th min of reperfusion (groups A and C) and at 120th min of reperfusion (groups B and D). The drug U-74389G was administered only in groups C and D. U-74389G administration significantly decreased the predicted albumin levels by 3.63% ± 0.87% (p = 0.0001). Reperfusion time non-significantly increased the predicted albumin levels by 0.72% ± 1.04% (p = 0.4103). However, U-74389G administration and reperfusion time together significantly decreased the predicted albumin levels by 2.02% ± 0.54% (p = 0.0005). U-74389G administration whether it interacted or not with reperfusion time has significant decreasing short - term effects on albumin levels. It seems that the antioxidant capacity is associated with albumin catabolism.

Abstract
OBJECTIVE This experiment evaluated the influence of erythropoietin (Epo) in an animal model of uterine ischemia reperfusion using the quoting established protocol. DESIGN The effects of erythropoietin treatment were evaluated by mean uterus inflammation (UI) lesions. UI lesions were determined at the 60th reperfusion min (for groups A and C) and at the 120th reperfusion min (for groups B and D). Groups A and B received no drugs, whereas rats from groups C and D were administered with erythropoietin. METHODS 40 rats of mean mass 247.7 g were employed for the study. RESULTS Epo administration non-significantly decreased the UI scores [without lesions] by 0.1 [-0.6244129 - 0.4244129] (p = 0.6294)). Reperfusion time kept non-significantly increased the UI scores by [without lesions] 0.15 [-0.60230385 - 0.50230385] (p = 0.5782). Together, Epo administration combined with reperfusion time non-significantly decreased the UI scores by [without lesions] 0.0727273 [-0.3886782 - 0.2432236] (p = 0.6439). CONCLUSIONS Epo administration whether it interacted or not with reperfusion time non-significantly short-term decreased the UI lesions scores. Perhaps, a longer study time than two hours or a higher Epo dose may provide more significant effects.

Abstract
Epidemiologic and clinicopathologic features, therapeutic strategies, and prognosis for acinic cell carcinoma of the major and minor salivary glands are critically reviewed. We explore histopathologic, histochemical, electron microscopic and immunohistochemical aspects and discuss histologic grading, histogenesis, animal models, and genetic events. In the context of possible diagnostic difficulties, the relationship to mammary analog secretory carcinoma is probed and a classification is suggested. Areas of controversy or uncertainty, which may benefit from further investigations, are also highlighted.

Abstract
BACKGROUND Extracapsular spread (ECS) in cervical lymph nodes is the single-most prognostic clinical variable in oral squamous cell carcinoma (OSCC), but diagnosis is possible only after histopathological examination. A promising biomarker in the primary tumour, alpha smooth muscle actin (SMA) has been shown to be highly prognostic, however, validated biomarkers to predict ECS prior to primary treatment are not yet available. METHODS In 102 OSCC cases, conventional imaging was compared with pTNM staging. SERPINE1, identified from expression microarray of primary tumours as a potential biomarker for ECS, was validated through mRNA expression, and by immunohistochemistry (IHC) on a tissue microarray from the same cohort. Similarly, expression of SMA was also compared with its association with ECS and survival. Expression was analysed separately in the tumour centre and advancing front; and prognostic capability determined using Kaplan-Meier survival analysis. RESULTS Immunohistochemistry indicated that both SERPINE1 and SMA expression at the tumour-advancing front were significantly associated with ECS (P<0.001). ECS was associated with expression of either or both proteins in all cases. SMA+/SERPINE1+ expression in combination was highly significantly associated with poor survival (P<0.001). MRI showed poor sensitivity for detection of nodal metastasis (56%) and ECS (7%). Both separately, and in combination, SERPINE1 and SMA were superior to MRI for the detection of ECS (sensitivity: SERPINE1: 95%; SMA: 82%; combination: 81%). CONCLUSION A combination of SMA and SERPINE1 IHC offer potential as prognostic biomarkers in OSCC. Our findings suggest that biomarkers at the invasive front are likely to be necessary in prediction of ECS or in therapeutic stratification.

Abstract
BACKGROUND The overall world prevalence of rheumatoid arthritis (RA) ranges from 0.5-1.0%. The annual incidence of RA in most European countries ranges from roughly 0.4 to >2.5 per 1,000 adults, increasing with age. A significant proportion of newly diagnosed cases will evolve into true erosive RA. METHODS The aim of this cohort study was to study the characteristics of new developing, acute (<1 year), rheumatoid arthritis in an elderly (>65 years) population; its presenting features, accompanying manifestations and laboratory findings. One hundred twenty eight patients (103♀, 25♂) who presented to the rheumatology outpatients clinic with new-onset RA were included in the study. 42.2% of the patients had pre-existing osteoarthritis. RESULTS At presentation, 14.3% of the patients had systemic manifestations (fever, weight loss), 25.78% reported concomitant sicca symptomatology, and 50.9% were found to have abnormal haematological parameters (anemia and/or thrombocytosis). Clinical and laboratory parameters of the disease were analyzed and related to disease manifestations.. Haematological abnormalities were found to be associated both with increased inflammatory markers, as well as with increased titres of rheumatoid factor (RF), but not anti - cyclic citrullinated peptide (CCP) antibodies, in contrary to systemic manifestations which were not found to be related to the above mentioned parameters. CONCLUSIONS As the global population is becoming older, physicians will be challenged with the recognition and treatment of these conditions and their particular features in an increasing number of geriatric patients; within the context of the specific characteristics and comorbidities of this age group.

Abstract
OBJECTIVES Patients with clinical signs of vasculopathy were screened with capillaroscopy for microangiopathy, and its presence was evaluated in the diagnosis of antiphospholipid syndrome (APS). For this purpose, autoantibody profiles in high risk patients with microhaemorrhages were correlated with thrombotic events. METHODS 738 patients from a Rheumatology Outpatients cohort were consecutively screened with capillaroscopy. Patients with microhaemorrhages were selected from the total of individuals screened and tested for anticardiolipin (αCL) and anti-beta2 glycoprotein 1 (anti-β2GP1) Abs. Positive autoantibody profile was subsequently correlated with arterial and venous thrombotic events. Patients with scleroderma were excluded from the analysis. RESULTS 149 patients with various rheumatologic conditions and capillary microhaemorrhages were included in the study. Antiphospholipid profile screening in these individuals revealed a 15.4% of newly diagnosed secondary laboratory APS. αCL antibodies and anti-β2-glycoprotein 1 (anti-β2GP1 Abs were both found to independently correlate significantly with thrombotic events. Subanalysis of the type of anti-β2GP1 Abs indicated that the correlation with thrombotic events was significant for IgG-type (p<0.001) and IgM-type (p=0.051), but not IgA-type Abs (p=0.292). CONCLUSIONS In patients with microhaemorrhages, αCL and anti-β2GP1 Abs were associated with thrombotic events. The observation that, although IgA type-anti-β2GP1 Abs were detected in patients with microangiopathy, they lacked any significant association with thrombotic complications, suggests, that either the type/conformation of the autoantibodies and/or additional factors may be critical for the development of thromboses. In conclusion, capillaroscopy can aid diagnostically to screen for or verify APS in combination with other parameters.

Abstract
BACKGROUND AND AIM To present our experience with unexpected findings during hernia surgery, either unusual hernial contents or pathologic entities, like neoplastic masses, masquerading as a hernia. PATIENTS AND METHODS We studied retrospectively 856 patients with inguinal hernia who were admitted to our surgical department over a 9-year period. In addition, our study included patients complaining of inguinal protrusion, even without a definitive diagnosis of inguinal hernia upon admission. RESULTS Five patients presented with unusual hernial contents. Three of them had a vermiform appendix in their sac. Acute appendicitis (Amyands hernia) was found in only one case. One patient had epiploic appendagitis related with a groin hernia. Moreover, an adult woman was diagnosed with ovarian and tubal inguinal hernia. Finally, we report a case of a massive extratesticular intrascrotal lipoma, initially misdiagnosed as a scrotal hernia. CONCLUSION a hernia surgeon may encounter unexpected intraoperative findings. It is important to be prepared to detect them and apply the appropriate treatment.

Abstract
BACKGROUND Diabetes mellitus is associated with a variety of musculoskeletal disorders. The prevalence of connective tissue disorders in these patients has increased in the recent years affecting significantly their quality of life. METHODS-RESULTS We conducted a pilot study including 208 sequentially selected patients with type 2 diabetes mellitus regularly followed-up at the Diabetes Center of the Hippokration University Hospital. Among the diabetic patients who were screened according to the Short Musculoskeletal Function Assessment Questionnaire for musculoskeletal symptoms and findings, 82.6% were found to exhibit musculoskeletal abnormalities, mainly of the degenerative, noninflammatory type. CONCLUSIONS Musculoskeletal disorders are a common finding among patients with type 2 diabetes. Obesity and accumulation of abnormally glycosylated byproducts have been proposed as potential pathogenetic mediators of these connective tissue abnormalities. Of particular interest is, however, the common association of osteoarthritis, involving even non-weight bearing joints in patients with type 2 diabetes, indicating a common pathophysiologic mechanism connecting these two clinical conditions.

Abstract
Previous investigations failed to demonstrate mast cells in the alimentary tract and extraparietal glands of the ferret. It was decided therefore to test this and assess factors that may be of influence. Major salivary glands and tongues of mature ferrets, which had been fixed in formalin-calcium, were examined by means of light microscopical histochemistry. Staining of paraffin sections with techniques depending on basic dyes or esterolytic activity was carried out for conventional times with and without previous oxidation, hot acid hydrolysis, and trypsin and beta-glucuronidase digestion. Aldehyde fuchsin and high iron diamine consistently revealed the presence of few mast cells in interstitial stroma of salivary glands and lingual musculature, and in the lamina propria of lingual mucosa. Alcian blue at 0.5 M MgCl2 and safranin produced less consistent results, and even fewer metachromatic mast cells were detected. No staining of mast cells was obtained with the technique for naphthol AS-D chloroacetate esterase. Pretreatment did not increase the numbers and/or staining reactions of mast cells. The results refute the previous misconception and suggest that ferret is a species with a low incidence of mast cells largely expressing a connective-tissue phenotype.

Abstract
Three grouped, small polypoid lesions were removed from the right lateral border of tongue of a healthy male aged 12 years. They were composed of packed, mature striated muscle fibres covered by oral epithelium and thinned lamina propria. Hamartomatous growth of striated muscle, or herniation through underdeveloped lamina propria is postulated to explain the exceedingly rare clinicopathological features.

Abstract
A case of primary meningioma of the scalp is presented in which the anatomical association with a previous skull fracture is demonstrated and pathogenesis discussed. The investigations and surgical treatment are briefly described. Review of the literature reveals a strong association between trauma of the central nervous system and intracranial meningioma. Occasional reports also exist of extra-cranial meningioma following trauma. This is, however, the first report of such an association in the scalp.

Abstract
To assess the time-dependent changes in renal function in relation to antioxidant and lipid-lowering effects of fluvastatin in hyperlipidemic renal transplant recipients, 20 patients were treated with fluvastatin 40 mg/d for 12 months, after failure of a dietary program. Plasma malondialdehyde (MDA) levels and lipid profiles were evaluated in relation to serum creatinine and calculated creatinine clearances 18 months before and during the fluvastatin treatment. Mean baseline lipid values were: total cholesterol 318 mg/dL, triglycerides 212 mg/dL, LDL cholesterol 219 mg/dL, HDL cholesterol 58 mg/dL, apolipoprotein A 176 mg/dL, and apolipoprotein B 145 mg/dL. During 12 months of treatment, fluvastatin produced consistent and significant reductions in total and LDL cholesterol (-18.4% and -24.1%), triglycerides (-17.7%), and apolipoprotein B (-22.7%) as well as an increase in HDL cholesterol (12.3%) and apolipoprotein A (9.2%). Plasma MDA levels decreased by 41.8% (from 3.5 +/- 0.3 to 1.8 +/- 0.1 nmol/mL, P =.00002). Creatinine clearance, which had been declining at a rate of 0.32 mL/min/month during the previous 18 months before treatment, progressively improved during treatment, giving a positive slope of the creatinine clearance, which increased by 0.35 mL/min/month, (P =.016; 53.3 +/- 4.2 mL/min vs 49.8 +/- 4.1 mL/min pretreatment). Multiple linear regression analysis revealed that MDA was the parameter most closely associated with the variability in creatinine clearance. In conclusion, renal transplant patients with lipid abnormalities display renoprotective activity of fluvastatin, possibly due to its lipid-lowering and antioxidant effects.

Abstract
To explain the occurrence in salivary pleomorphic adenoma of structures with an arrangement and appearance of tumour cells resembling acini, two tumours showing such structures and, for comparison, a tumour showing goblet cells were examined with the use of histochemistry and immunocytochemistry for constituents of the salivary secretory process. One tumour consisted mainly of slightly granular cells with an acinar arrangement, which contained neutral and carboxylated glycoproteins, -SH groups and cytoplasmic epithelial membrane antigen. The second tumour showed a minor component of structures resembling mucous acini, which contained neutral and carboxylated glycoproteins, -SS- groups and fucoglycoconjugates. The goblet cells of the third tumour contained sulphated glycoproteins and were associated with cystic lumina. Acinar phenotypes in salivary pleomorphic adenoma could reflect either an unusual line of differentiation or luminal cells with increased synthesis and/or retention of variably mature glycoproteins different from those of goblet cells. Disordered secretion and externalization of glycoproteins are possible factors influencing phenotypes in this tumour.

Abstract
The spread and variation in 206Pb/207Pb ratios make Pb isotopes a powerful tool when it comes to detecting trends in airborne particulates originating mainly from power plants. This study was conducted to determine the source of pollution in Kozani area, an affected industrial area. Lead isotopic ratios of air filters under certain meteorological conditions were compared to Pb isotope analyses sampled from lignite mines, but also to Pb isotope analyses of cultivations in soil originating from the reclamation of old abandoned lignite-mines. The particles taken into consideration have an aerodynamic diameter less than 10 microm (PM10). The measurements were carried out in a central part of the town of Kozani, West Macedonia, for one year observation period. The lead isotope values of air filters and of wheat in the Kozani area are between the values of lignite Pb and of Greek gasoline.

Abstract
Von Ebner's gland of ferret was examined by means of light microscopy, protein, mucosubstance and enzyme histochemistry, and neurohistology. Acinar cells were replete with granules containing neutral mucosubstances and disulphides, and showed strong diffuse acid phosphatase activity and weak granular staining for peroxidase. Staining for cytochrome oxidase, succinate dehydrogenase, and NADH and NAD(P)H dehydrogenases was also seen. Basolateral plasmalemma of acinar cells showed weak, ouabain-sensitive Na+,K+-ATPase activity. Ductal cells were of a simple appearance, contained thiols and showed variable staining for acid phosphatase, dehydrogenases and cytochrome oxidase. Variable amounts of beta-glucuronidase reaction product were localized in the glandular parenchyma, being marked in atrophic areas. Prominent stellate myoepithelial cells embracing acini and also basal ductal cells were demonstrated by alkaline phosphatase. Thiamine pyrophosphatase reaction product was concentrated in blood vessels around parenchyma, with little Golgi-like staining in acinar cells. Acetylcholinesterase activity was associated with an extensive network of nerve fibres embracing parenchyma, whereas catecholamine fluorescence was not seen. The results suggest that the acini of von Ebner's gland of ferret synthesise neutral secretory glycoproteins and peroxidase. Water mobilization is inconspicuous. Lysosomal activities feature in the parenchyma, possibly a consequence of processing secretory products in acini, absorption in ducts and/or adaptation atrophy. The gland receives a rich cholinergic-type innervation, and has extensive myoepithelial and microvascular networks.
