A man with chronic kidney disease (CKD) under hemodialysis was diagnosed with acute promyelocytic leukemia (APL). He received arsenic trioxide as a single agent and achieved complete molecular remission without severe adverse events. Arsenic trioxide (ATO) can be used safely and effectively for APL with CKD.The key clinical message is to know that mechanical complications of myocardial infarction are rare but fatal. A high index of suspicion facilitates diagnosis. The presence of acute heart failure should ring an alarm. Other red flags are cardiogenic shock, new murmur, or evidence of hypoperfusion.A myometrial ectopic pregnancy is a rare and potentially fatal diagnosis. This diagnosis should be considered when presented with large increases in serum beta-hCG with no evidence of an intrauterine pregnancy, particularly with altered myometrium.A man undergoing hemodialysis was diagnosed with acute promyelocytic leukemia (APL). He received arsenic trioxide as a single agent and achieved complete molecular remission without severe adverse events. Arsenic trioxide can be used safely and effectively for patients with APL under hemodialysis.Patients with McCune-Albright Syndrome (MAS) should always attend regular follow-up. Beside the endocrinological aspects, the screening must take into account osteoarticular complications such as scoliosis, even in patients without fibrous dysplasia.Anaphylactic reactions, and especially the severe ones (types III and IV), should be kept in mind as considerable adverse effects while using blue dyes for SLNB.In immunocompromised patients, including patients with AIDS, with neurologic complaints, we propose including Cryptococcus meningoencephalitis in the differential diagnoses when the butterfly pattern is encountered on MRI.A broad spectrum of diseases can cause anemia and thrombocytopenia. Some of these diseases are a hematological emergency; others are benign diseases, so early and accurate diagnosis is crucial in managing such patients. Usually, IDA is associated with thrombocytosis or normal platelets; however, in rare cases, IDA can be associated with thrombocytopenia; even though, thrombocytopenia that occurs with IDA responds to iron therapy. Iron therapy rarely causes transient thrombocytopenia per se. We are reporting an African female patient who is found to have thrombocytopenia secondary to iron deficiency anemia (IDA), and she responded to iron replacement therapy initially with a transient drop in platelets, followed by a rapid rise in platelets till platelets reached the normal level.Surgical procedures requiring close contact with saliva, such as salivary gland surgery, may determine the risk of spreading the SARS-CoV-2 infection. The use of PPE and isolation settings are mandatory to protect health workers.

There are no disease-modifying therapies for the treatment of eosinophilic oesophagitis (EoE), which is driven by non-IgE-mediated allergic inflammation. A recent clinical trial of milk epicutaneous immunotherapy (EPIT) has shown initial promise, with 47% of treated EoE patients tolerating milk without recurrence of disease. Mechanisms of EPIT in EoE have not been studied in humans. Here, we identify transcriptional changes in the peripheral CD4

T-cell compartment during active EoE and following EPIT.

RNA isolation, sequencing and integrative data analysis were performed on peripheral CD4

T cells isolated from 15 of 20 patients enrolled in a clinical trial of EPIT for EoE. Gene expression changes in peripheral CD4

T cells were examined during diet therapy and following trial of milk antigen EPIT.

We identify 244 differentially expressed genes in peripheral blood CD4

cells of EoE patients consuming versus those eliminating milk, and 129 DEGs in CD4

cells were isolated after EPIT versus after plh distinct global transcriptional changes in CD4+ T cells, one feature of which is an IFN response signature. Clinically favorable response to EPIT is likely multifactorial but is associated with a distinct transcriptional profile in peripheral CD4+ cells supporting the hypothesis that EPIT alters peripheral CD4+ responses in EoE patients.

Corticosteroids have been reported to reduce the mortality rates in patients with coronavirus disease 2019 (COVID-19). Additionally, the role of high-dose methylprednisolone pulse therapy in reducing mortality in critically ill patients has also been documented. The purpose of this study is to identify patients with COVID-19 who are suitable for methylprednisolone pulse therapy.

This was a retrospective study that included patients with COVID-19 receiving methylprednisolone pulse therapy (≥250 mg/day for 3 days) with subsequent tapering doses at our hospital between June 2020 and January 2021. We examined the differences in background clinical factors between the surviving group and the deceased group.

Out of 156 patients who received steroid therapy, 17 received methylprednisolone pulse therapy. Ten patients recovered (surviving group) and seven patients died (deceased group). The median age of the surviving and deceased groups was 64.5 years (range, 57-85) and 79 years (73-90), respectively, with a significant difference (p=0.004). Five of the deceased patients (71%) had developed serious complications associated with the cause of death, including pneumothorax, pneumomediastinum, COVID-19-associated pulmonary aspergillosis, cytomegalovirus infection, and bacteremia. On the other hand, out of the 10 survivors, only one elderly person had cytomegalovirus infection and the rest recovered without complications.

Administration of methylprednisolone pulse therapy with subsequent tapering may be an effective treatment in patients with COVID-19 up to the age of early 70s; however, severe complications may be seen in elderly patients.

Chronic thromboembolic pulmonary hypertension (CTEPH) is one of the leading causes of pulmonary hypertension. Diagnosis of CTEPH can be established using various imaging techniques, including ventilation-perfusion scintigraphy (VQ) and multidetector computed tomography pulmonary angiography (CTPA). The aim of this study was to determine the frequency of direct pulmonary vascular, parenchymal lung, and cardiac abnormalities on CTPA in patients with CTEPH and to compare the diagnostic accuracy of both VQ scan CTPA in detecting CTEPH.

We retrospectively included 54 patients who had been referred for pulmonary hypertension service (20 males, 34 females). All patients had VQ scan and CTPA within 15 days and underwent pulmonary artery endarterectomy (PEA) thereafter. VQ scans were reported according to modified PIOPED (Prospective Investigation of Pulmonary Embolism Diagnosis) criteria. CTPA was considered as diagnostic for CTEPH if it showed presence of thrombus, webs, stenosis, or perfusion lung abnormalities scan and CTPA are highly sensitive for the detection of CTEPH confirmed by PEA. Most CTEPH patients had several pulmonary vascular, parenchymal lung and cardiac abnormalities. There was no sign with 100% sensitivity on CTPA for CTEPH detection.Background Raynaud's phenomenon is induced by excessive vasoconstriction of the peripheral microcirculation in response to environmental factors, essentially cold, but also stress or emotions. The objective of the present study is to evaluate the impact of global warming on the worldwide prevalence and severity of Raynaud's phenomenon over the 21 st century. Method We first estimated the correlation between average temperature and prevalence and severity of Raynaud's phenomenon. Then, we mapped the prevalence and the severity of Raynaud's phenomenon worldwide at Christmas 1999 using historical data and, using climate projections from the Inter-Sectoral Impact Model Intercomparison Project, we predicted the prevalence and severity of Raynaud's phenomenon at Christmas 2099 according to four greenhouse-gas emission scenarios. Results The prevalence of Raynaud's phenomenon in the general population is expected to decrease by 0.5% per degree Celsius increase. Furthermore, patients are expected to suffer from one less attack per week for each increase of 2.5 degrees Celsius. Conclusions Our study shows that global warming may have a significant impact on the prevalence and the severity of Raynaud's phenomenon over the 21 st century. However, as expected, this will greatly depend on the level of greenhouse-gas emissions.

The pathogenesis of contact dermatitis, a common inflammatory skin disease with limited treatment options, is held to be driven by inflammasome activation induced by allergens and irritants. We here aim to identify inflammasome-targeting treatment strategies for irritant contact dermatitis.

A high content screen with 41,184 small molecules was performed using fluorescent Apoptosis associated speck-like protein containing a CARD (ASC) speck formation as a readout for inflammasome activation. Hit compounds were validated for inhibition of interleukin (IL)-1β secretion. Of these, the approved thiuramdisulfide derivative disulfiram was selected and tested in a patch test model of irritant contact dermatitis in 25 healthy volunteers. Topical application of disulfiram, mometasone or vehicle was followed by application of sodiumdodecylsulfate (SDS) for 24h each. Eczema induction was quantified by mexameter and laser speckle imaging. Corneocyte sampling of lesional skin was performed to assess inflammasome-mediatresents a potential treatment option for irritant contact dermatitis.

Appropriate cleaning and shaping and three-dimensional obturation of the root canal system lead to a successful endodontic treatment. To achieve this, complete knowledge of the internal anatomy of root canals is necessary. Therefore, this study evaluated the number and shape of mandibular premolar roots and canals and classified their Vertucci classification using cone-beam computed tomography (CBCT) images of an Iranian sample population.

This

study was performed on CBCT images of patients aged 20-70 years who had attended a dental radiology center in Isfahan. CBCT images were examined in coronal, sagittal, and especially axial dimensions. Descriptive statistics were calculated. Groups were compared using the Chi-square of the Statistical Package for the Social Sciences. The level of significance was predetermined as 0.05.

In both first and second premolars, the most common classes were Type I followed by Type V. learn more The Chi-square did not show significant differences between males and females in terms of Vertucci classes in the first (

= 0.305) or second premolar (

= 0.315).

Since a thorough knowledge of root canal anatomy is necessary for successful root canal treatment and almost one out of ten mandibular premolars has additional canal in their root canal system, accurate evaluating of preoperative radiographs, taking CBCT images if necessary, and probing the root canal system with fine and precurved files should be done to negotiate the entire canal system.
