Basal cell carcinomas (BCCs) are common malignancies that usually show clear histomorphologic features, but in certain instances, it can display different patterns of differentiation leading to potential diagnostic confusion. BCCs with neuroendocrine differentiation/expression have been mentioned only briefly in the literature. In this study, we present cases of BCCs with neuroendocrine differentiation/expression that demonstrate reproducible histopathological features. Twenty-four cases were included in the study. All tumors showed conventional histopathologic features that are seen in BCCs, but in addition, all the tumors showed large, hyperchromatic, pleomorphic, mononuclear, and multinucleate cells with intracytoplasmic inclusions and intranuclear cytoplasmic invaginations, with rare cases showing stippled nuclei (salt-and-pepper appearance). These histologic features were somewhat concerning for a neuroendocrine carcinoma; thus, immunohistochemistry studies were performed in all cases at the time of di of histopathologic features that are present in cases of BCC that are associated with neuroendocrine expression that can potentially be interpreted differently and can create a diagnostic pitfall. Neuroendocrine expression in BCCs is yet uncertain, and further studies are required to fully understand this phenomenon. Smad phosphorylation To avoid diagnostic pitfalls, dermatopathologists must be aware of these unusual histopathologic features and aberrant immunostaining in such tumors; hence, it is advised to perform a thorough histologic inspection.

Leiomyosarcomas of the lower extremity are heterogeneous tumors with high recurrence and metastasizing rates, which, rarely, can suffer a dedifferentiation process, making them extremely aggressive and unpredictable. We report the case of a 72-year-old female patient who presented the clinical and histopathological features of a rare leiomyosarcoma of the foot that was completely excised, but because of the interruption of adjuvant oncological treatment and lack of compliance for the follow-up, the patient suffered a dedifferentiation process and the tumor metastasized in the fingers-an unprecedented site for this type. The present case proves the fact that there is still a lot we do not know about the behavior of this disease, and there is always room to learn. Also, through this report, we are emphasizing a frequently encountered and never-ending problem in our country-that of difficult and resource-consuming cases derived from disconsidering medical advice by noncompliant patients when faced with a maligom disconsidering medical advice by noncompliant patients when faced with a malignant diagnosis, making all attempts to offer them a better quality of life futile.

Sarcoidosis induced by anti-PD1 or anti-PDL1 agents such as atezolizumab has recently been reported. It has been suggested that the predilection of sarcoidosis to affect scars is due to the presence of antigens or foreign bodies that can serve as a stimulus for granuloma formation. However, to the best of our knowledge, sarcoidosis-specific skin lesions have not to date been reported involving xanthelasma. We report a patient who developed specific lesions of sarcoidosis infiltrating some xanthelasmata 6 months after starting treatment with atezolizumab. A 69-year-old woman was referred to the dermatology department for infiltration of xanthelasmata. The patient was being treated with atezolizumab for metastatic uterine carcinosarcoma. Cutaneous biopsy from an infiltrated xanthelasma and from still yellow, no infiltrated xanthelasma showed differing proportions of foamy histiocytes and sarcoid granulomas. On physical examination, erythemato-marronaceous papules clustered on both knees, and not previously dehistiocytes of xanthelasma seem to be replaced by or evolve to epithelioid cells to form sarcoid granulomas. The possible pathogenic mechanism is discussed. Dermatologists and dermatopathologists should bear in mind that sarcoidosis can present as infiltration of pre-existing xanthelasmata.

This review will focus on identifying causes of zonulopathy during cataract surgery and discuss various modalities for treatment.

There are multiple different options for capsular bag support in the setting of zonulopathy, including capsular or iris hooks, capsular tension rings as well as capsular tension segments (CTS). Surgical techniques on how to insert these devices are many and can be customized based upon the surgeon's preference and the patient's eye anatomy.

Recognizing zonular weakness is critical to achieve stable postoperative vision and avoid future complications. Depending on the degree of zonulopathy, various treatment options can be pursued, ranging from capsular tension hooks or iris hooks, capsular tension rings or sutured or scleral fixated CTS.

These patients went through 3 psychological stages extremely uncertainties during the initial diagnostic stage, complicated feelings of negativity during the treatment stage, and positive growth in the recovery stage. It is important for nurses to provide holistic care.This prospective pre-/posttest pilot studied a mindfulness-based stress reduction (MBSR) intervention first, to reduce self-reported stress and improve compassion satisfaction; and second, to reduce physiological indices of stress. Even small interventions of MBSR before a shift effectively reduces the physiological indices of stress and may help reduce compassion fatigue and burnout in nurses.Although hemodialysis treatment is one of the main treatment methods in chronic kidney failure, it also causes many health problems. A variety of complementary and integrative therapies are used to relieve or minimize hemodialysis symptoms. Fatigue (60%-97%) is also one of these problems. Therefore, we have conducted a systematic review to determine the effect of complementary and integrative therapies on fatigue in hemodialysis patients. Relevant studies published from 2005 to 2019, in PubMed, EBSCOhost, ScienceDirect, and Cochran Library databases have been reviewed. In the study, initially, 21 039 pieces of data were obtained, and then 14 randomized controlled studies meeting the inclusion criteria were reviewed. The methodological qualities of the articles included in the study were determined by using the quality evaluation checklist in Jadad randomized controlled studies. In the literature, acupressure, aromatherapy, reflexology, massage, and yoga practice were found to be applied to hemodialysis patients and be effective in reducing pain and anxiety as well as improving sleep quality. It is recommended that these methods be included in the routine clinical care of patients receiving hemodialysis.Through a difficult encounter with a new patient, the author became immersed in the messiness of patient care and learned that goals need to be defined and hard fought. The lesson learned serves as a reminder that compassion for our patients is necessary to help understand their fears and anxieties.Faith community nurses receive additional education in holistic health and intentional spiritual care, including self-caring. This study used an online survey to explore self-caring practices of faith community nurses and clinical nurses. Despite sample limitations, faith community nurses reported significantly higher levels of self-caring practices than clinical nurses.Von Willebrand disease (VWD) is the most frequent inherited bleeding disorder caused by quantitative or qualitative defects of von Willebrand factor (VWF). This protein far from simplicity constitutes a very complex molecular model, remaining unravelled yet many aspects of it, even though the VWF gene (VWF) was cloned already in 1985 and the structure of VWF well defined. VWD diagnosis is difficult to achieve in a significant proportion of patients due to both disease heterogeneity and limitations in existing test processes. The cornerstone of diagnosis relies on interpretation of VWF test results, the presence of clinical manifestations of bleeding, especially mucocutaneous, and (in most cases) a positive family history. However, even with a significant bleeding history, a family history may not be positive due to factors of incomplete penetrance and variable expressivity that affect genetic changes. The laboratory diagnosis of VWD can be difficult, as the disease is heterogeneous and an array of assays is required to describe the phenotype. Basic classification of quantitative (type 1 and 3) and qualitative (type 2 variants) VWD requires determination of VWF antigenic (VWFAg) levels and assaying of VWF ristocetin cofactor (VWFRCo) activity. The latter is required for identifying and subtyping VWD, but the assay is poorly standardized. For that reason, novel VWF activity assays have been developed awaiting more extensive comparison data between different methodologies and requiring validation on larger patient series. The qualitative type 2 VWF deficiency can be further divided into four different subtypes (A, B, M and N) using specific assays that measure other activities or the size distribution of VWF multimers. However, frequently, it may be difficult to correctly classify the VWD phenotype, and genetic analysis is through mutation identification may provide a tool to clarify the disorder.Fibrinolysis can be abnormally activated in several critical care settings but it's often misdiagnosed by standard laboratory tests. Although rotational thromboelastometry can assess the whole coagulative process, its ability to detect fibrinolysis has been questioned. Aim of this study was to investigate the ability of thromboelastometry in detecting induced fibrinolysis in an in-vitro model. Whole blood samples were taken from 18 healthy volunteers. Each sample was split and added with increasing urokinase concentrations till to reach 0, 50, 75 and 100 IU/ml. Thromboelastometry tests, extem and aptem, were performed on the obtained samples. If significant lysis at 50 IU/ml was recorded, also 10, 25 and 35 IU/ml drug concentrations were tested. No lytic effects were detected in 10 IU/ml samples. Lysis variables were the most sensitive in detecting fibrinolysis even at 25 IU/ml (P  less then  0.05). Clot firmness parameters were also affected by urokinase, but only at the two highest drug concentrations (P  less then  0.05). Extem/aptem ratio enhanced the sensitivity of these parameters only if lysis was more marked. Analysing groups of different lysis severity, the time to achieve maximum clot firmness could anticipate an ongoing fulminant or intermediate lysis with 100% sensitivity and 100% specificity (P  less then  0.05) when lower than 1341.5 s. Rotational thromboelastometry could detect fibrinolysis when it was induced in vitro by 25 IU/ml urokinase or more. Apart from the parameters specific for lysis, time to achieve maximum clot firmness appeared as the earliest indicator of fibrinolysis with high sensitivity and specificity especially if a more intense lysis was going on.
