The debate on mixed states (MS) has been intense for decades. However, several points remain controversial from a nosographic, diagnostic, and therapeutic point of view. The different perspectives that have emerged over the years have turned into a large, but heterogeneous, literature body. The present review aims to summarize the evidence on MS, with a particular focus on mixed depression (MxD), in order to provide a guide for clinicians and encourage the development of future research on the topic. First, we review the history of MS, focusing on their different interpretations and categorizations over the centuries. In this section, we also report alternative models to traditional nosography. Second, we describe the main clinical features of MxD and list the most reliable assessment tools. Finally, we summarize the recommendations provided by the main international guidelines for the treatment of MxD. Our review highlights that the different conceptualizations of MS and MxD, the variability of clinical pictures, and the heterogeneous response to pharmacological treatment make MxD a real challenge for clinicians. Further studies are needed to better characterize the phenotypes of patients with MxD to help clinicians in the management of this delicate condition.

Dysbarism is a general term which includes the signs and symptoms that can manifest when the body is subject to an increase or a decrease in the atmospheric pressure which occurs either at a rate or duration exceeding the capacity of the body to adapt safely. In the following review, we take dysbarisms into account for our analysis. Starting from the underlying physical laws, we will deal with the pathologies that can develop in the most frequently affected areas of the body, as the atmospheric pressure varies when acclimatization fails. Manifestations of dysbarism range from itching and minor pain to neurological symptoms, cardiac collapse, and death. Overall, four clinical pictures can occur: decompression illness, barotrauma, inert gas narcosis, and oxygen toxicity. We will then review the clinical manifestations and illustrate some hints of therapy. We will first introduce the two forms of decompression sickness. In the next part, we will review the barotrauma, compression, and decompression. The last three parts will be dedicated to gas embolism, inert gas narcosis, and oxygen toxicity. Such an approach is critical for the effective treatment of patients in a hostile environment, or treatment in the emergency room after exposure to extreme physical or environmental factors.

Currently, there a growing demand of data produced and stored in clinical domains. Therefore, for effective dealings of massive sets of data, a fusion methodology needs to be analyzed by considering the algorithmic complexities. For effective minimization of the severance of image content, hence minimizing the capacity to store and communicate data in optimal forms, image processing methodology has to be involved. In that case, in this research, two compression methodologies: lossy compression and lossless compression were utilized for the purpose of compressing images, which maintains the quality of images. Also, a number of sophisticated approaches to enhance the quality of the fused images have been applied. The methodologies have been assessed and various fusion findings have been presented. Lastly, performance parameters were obtained and evaluated with respect to sophisticated approaches. Structure Similarity Index Metric (SSIM), Mean Squared Error (MSE), Peak Signal-to-Noise Ratio (PSNR) are the metrics, which were utilized for the sample clinical pictures. Critical analysis of the measurement parameters shows higher efficiency compared to numerous image processing methods. This research draws understanding to these approaches and enables scientists to choose effective methodologies of a particular application.

The term spina includes several types of congenital malformations including closed spinal dysraphisms, among these 10% are dermal sinuses.Our series includes 29 patients, the majority of which were asymptomatic, but these can present with different clinical pictures including neurological and / or infectious signs indicating a neglected dermal sinus and which therefore requires urgent treatment in the environment. Neurosurgical.MRI confirmed the diagnosis showing the dermal sinus tract communicating from the surface of the skin to the intra-dural space.Once the diagnosis has been made, surgical treatment becomes imperative and urgent because, despite the benignity of the lesion, the majority of which are located in the lumbar region, can lead to formidable neurological sequelae compromising the functional prognosis or even the vital prognosis in some cases.All of our patients were operated on and we obtained 90% good results, however we deplore one case of aggravation and one death.

Sarcoidosis is a chameleon disease of unknown etiology, characterized by the growth of non-necrotizing and non-caseating granulomas and manifesting with clinical pictures that vary on the basis of the organs that are mainly affected. Lungs and intrathoracic lymph nodes are the sites that are most often involved, but virtually no organ is spared from this disease. Histopathology is distinctive but not pathognomonic, since the findings can be found also in other granulomatous disorders. The knowledge of these findings is important because it could be helpful to differentiate sarcoidosis from the other granulomatous-related diseases. This review aims at illustrating the main clinical and histopathological findings that could help clinicians in their routine clinical practice.

The alpha-gal syndrome is an allergic syndrome that comprises two clinical pictures: an immediate hypersensitivity to drugs containing alpha-gal and a delayed hypersensitivity to the ingestion of red mammalian meat. This allergic syndrome is often under-recognized, and patients are mislabeled with diagnosis as spontaneous urticaria or idiopathic anaphylaxis. Even though less frequently, children could also be of interest, especially in tick-endemic areas. In most cases, a positive anamnesis for tick bites months before the onset of symptoms is recorded. The clinical manifestations could range from asymptomatic cases to severe anaphylaxis. The most frequently used diagnostic test is the determination of specific IgE for alpha-gal. Oral provocation test is usually reserved to unclear cases or to verify tolerance after diet. No long-term follow-up studies have been published, although an elimination diet could lead to a decrease of specific IgE for alpha-gal and a possible reintroduction of some avoided foods. This paper provides a literature review, focused on pediatric age, and an evaluation of available diagnostic tests. We analyze the correlation between tick bites and symptom onset and unfold the different clinical pictures to help clinicians to promptly recognized this syndrome. Lastly, we address unmet needs in this specific allergy.

<b><i>Introduction:</i></b> Wheat is the most important cereal for human nutrition but its high consumption is associated to an increasing complaint of wheat-related disorders, many of which are allergic in nature and different in respect to the involved allergens. In this study, we compared the clinical aspects of wheat allergy presented by patients sensitized to Tri a 19 in respect to those presented by patients sensitized to Tri a 14. <b><i>Methods:</i></b> With this aim, we selected patients sensitized to 1 or both of the 2 allergens, and among these we identified those who were really wheat allergic and reactive on the basis of a standardized methodology. We evaluated the clinical features such as the kind and severity of symptoms, the coexistence of triggering factors such as physical exercise and NSAIDs and alcohol consumption, and the association with other allergens and with various immunologic parameters. Wheat allergy in Tri a 19 sensitized patients was confirmed through a questionnaire while the patients sensitized to Tri a 14 underwent wheat challenge with 100 g of pasta followed by exercise on a treadmill. <b><i>Results:</i></b> Seventy-nine patients sensitized to Tri a 14 and 40 patients sensitized to Tri a 19 were recruited. The 2 sensitizations were independent with a significant inverse relation (<i>p</i> &#x3c; 0.00001). The Tri a 19 sensitized patients presented, in respect to the Tri a 14 sensitized ones, an older age (<i>p</i> = 0.0017), a higher risk to be wheat allergic (<i>p</i> &#x3c; 0.0001), a higher severity of the reactions (<i>p</i> &#x3c; 0.00001) and a higher association with some cofactors, namely alcohol (<i>p</i> &#x3c; 0.0005) and physical exercise (<i>p</i> = 0.003). On the contrary, Tri a 14 sensitization was associated with atopy (<i>p</i> &#x3c; 0.0001), with a higher probability of patients being asymptomatic (<i>p</i> &#x3c; 0.0001) and being sensitized to other foods, in particular to nuts and cereals (<i>p</i> &#x3c; 0.00001). <b><i>Conclusions:</i></b> Sensitization to Tri a 19 or Tri a 14 determines different clinical pictures. In particular, sensitization to Tri a 19 implies a higher probability of severe reactions, even dependent on daily triggers, while that to Tri a 14 implies a higher cross-reactivity with other foods but it’s more frequently asymptomatic, making a food challenge necessary to prevent useless food avoidance.

Large variability in COVID-19 clinical progression urges the need to find the most relevant biomarkers to predict patients’ outcomes. We evaluated iron metabolism and immune response in 303 patients admitted to the main hospital of the northern region of Portugal with variable clinical pictures, from September to November 2020. One hundred and twenty-seven tested positive for SARS-CoV-2 and 176 tested negative. Iron-related laboratory parameters and cytokines were determined in blood samples collected soon after admission. Demographic data, comorbidities and clinical outcomes were recorded. Patients were assigned into five groups according to severity. Serum iron and transferrin levels at admission were lower in COVID-19-positive than in COVID-19-negative patients. The levels of interleukin (IL)-6 and monocyte chemoattractant protein 1 (MCP-1) were increased in COVID-19-positive patients. The lowest serum iron and transferrin levels at diagnosis were associated with the worst outcomes. Iron levels negatively correlated with IL-6 and higher levels of this cytokine were associated with a worse prognosis. Serum ferritin levels at diagnosis were higher in COVID-19-positive than in COVID-19-negative patients. Serum iron is the simplest laboratory test to be implemented as a predictor of disease progression in COVID-19-positive patients.

Abstract Background Life-threatening streptococcal sepsis nowadays represents an uncommon event in previously healthy infants and children. Critically ill patients suffering from severe streptococcal sepsis complications may present with pre-antibiotic era clinical pictures and require a timely clinical approach to achieve restitutio ad integrum. Results We report a series of four patient groups affected by an uncommon life-threatening streptococcal sepsis, each of them exhibiting some distinct features. Streptococcus Agalactiae sepsis was associated with cerebral thrombotic/ischaemic lesions, whereas severe cardiogenic shock was prominent in the Streptococcus Viridans group; Streptococcus Faecalis and β-hemolytic group A Streptococcus patients mostly reported lung complications. Conclusions Previous antibiotic treatments should not delay aggressive treatment in the intensive care setting. Early diagnostic suspicion, as well as appropriate and aggressive treatment provided within an intensive care setting are crucial for the clinical outcome.

Abstract Background Appendix’ anatomical variations are a rare occurrence which can mislead diagnosis and delay appropriate treatment. Case presentation We present a 9-year-old female patient that came with a clinical picture compatible with acute appendicitis. However, a cecal mass was identified instead of an inflamed appendix during surgery. Therapeutic decisions were extremely challenging due to clinical deterioration and an uncertain etiology. Only the histopathology report revealed the presence of a complete subserosal appendix which was responsible for the entire symptomatology. Here, we review all case reports regarding intramural, intracecal or subserosal appendixes. A discussion of the general approach to this specific case and the importance of consensual diagnostic criteria for these specimens are also presented. At last, an incidental finding is exposed and final treatment options are discussed given the overall presentation. Conclusions Considering these variants would guide physicians towards a more accurate approach to similar clinical pictures and hence an improved long-term prognosis.
