Article Synopsis
  • * The combination of Ruxolitinib (a JAK inhibitor) and Resminostat (an HDAC inhibitor) has shown promising results in reducing tumor cell migration and angiogenesis in experimental models of cutaneous T-cell lymphoma (CTCL).
  • * Treatment with these inhibitors resulted in a significant decrease in the migration of CTCL cells and blood vessel formation, indicating their potential as effective anti-angiogenic therapies for improving treatment strategies in CTCL.

Gallstone ileus is a relatively rare complication of cholelithiasis, and an uncommon cause of small bowel obstruction most commonly seen in elderly and debilitated people with associated comorbidities. Symptoms of gallstone ileus are insidious and may be vague while the delay in diagnosis results in a high mortality rate. Herein we report two cases of gallstone ileus in elderly patients with complex medical history who presented at the emergency department with abdominal pain and distension, vomiting and fluid/electrolyte disorders due to cholecysto-enteric fistula and bowel obstruction.

Article Synopsis
  • Retroperitoneal abscesses are rare but serious infections in the abdomen that can be difficult to diagnose due to vague symptoms.
  • The condition can lead to severe health complications if not identified and treated promptly.
  • The case presented involves a 32-year-old intravenous drug user who developed a retroperitoneal abscess after injecting drugs into a vein, experiencing high fever, hiccups, and back pain as primary symptoms.

Psoriasis may affect patients' sleep. In order to examine this relationship, this study evaluated non-anxious and non-depressive patients with moderate to severe psoriasis before and after 6 months of systemic treatment. A prospective case-control study with 46 consecutive patients (mean age 51.

The combination of Resminostat (HDACi) and Ruxolitinib (JAKi) exerted cytotoxic effects and inhibited proliferation of CTCL cell lines (MyLa, SeAx) in previously published work. A xenograft tumor formation was produced by implanting the MyLa or SeAx cells on top of the chick embryo chorioallantoic membrane (CAM). The CAM assay protocol was developed to monitor the metastatic properties of CTCL cells and the effects of Resminostat and/or Ruxolitinib in vivo.

The serine/threonine kinase mechanistic target of rapamycin (mTOR) plays a pivotal role in the regulation of cell proliferation, survival, and motility in response to availability of energy and nutrients as well as mitogens. The mTOR signaling axis regulates important biological processes, including cellular growth, metabolism, and survival in many tissues. In the skin, dysregulation of PI3K/AKT/mTOR pathway may lead to severe pathological conditions characterized by uncontrolled proliferation and inflammation, including skin hyperproliferative as well as malignant diseases.

Introduction: Chlormethine gel is a skin-directed therapy recommended for patients with early-stage mycosis fungoides (MF) cutaneous T cell lymphoma.

Methods: Herein, we present three cases of patients with stage IB-IIB MF who were treated with chlormethine gel and concomitant therapies.

Results: All patients responded well to treatment with chlormethine gel; complete responses were observed with improvements in Modified Severity-Weighted Assessment Tool scores and severity of lesions; one patient reported an improvement in quality of life.

Background: The combination of JAK/STAT and HDAC inhibitors exerted beneficial effects in haematological malignancies, presenting promising therapeutic CTCL targets. We aim to investigate the efficacy of JAK1/2i ruxolitinib in combination with HDACi resminostat in CTCL in vitro.

Material & Methods: Non-toxic concentrations of ruxolitinib and/or resminostat were administered to MyLa (MF) and SeAx (SS) cells for 24h.

Cutaneous T-cell lymphoma is a heterogeneous group of non-Hodgkin's lymphoma, characterized by an infiltration of malignant T cells in the skin. The most common subgroups include mycosis fungoides followed by the aggressive leukaemic variant, Sézary syndrome. The pathophysiology of this neoplasm is poorly understood.

Purpose: Laryngeal squamous cell carcinoma (LSCC), a common type of head and neck cancer, is associated with high rates of metastasis and recurrence. In this study, we investigated the potential combinatorial prognostic value of NOTCH1, Vimentin (VIM), and Metastasis-associated 1 (MTA1) protein in LSCC, using immunohistochemistry.

Materials And Methods: Tissue specimens from 69 patients with LSCC were immunohistochemically evaluated for the protein expression of NOTCH1, VIM, and MTA1.

Background: Nasal polyposis (NP) and sinonasal inverted papillomas (SIP) are considered benign lesions capable of recurrence or malignant transformation although not with the same prevalence. Since fluctuations of Caveolin-1 and Notch-1 proteins expression have been reported in many pathologies, the current study aimed to investigate their involvement in the epithelial transformation observed in SIPs compared to NP.

Methods: Immunohistochemical expression of Caveolin-1 and Notch-1 proteins was assessed in 104 patients with sinonasal lesions (45 NP, 45 SIP and 14 NP with SIP), semiquantively (percentage times intensity).

Article Synopsis
  • About 5-10% of melanoma cases are hereditary, with CDKN2A and CDK4 being key genes linked to familial melanoma.
  • This study focused on analyzing these gene variants in Greek families with a history of melanoma, involving 52 families in total.
  • Findings showed that 46.2% of families had CDKN2A variants, which correlated with a younger age at melanoma diagnosis, but no significant links were found between CDKN2A mutations and MC1R gene variations.

Article Synopsis
  • * Fifteen SNPs were found significantly associated with melanoma risk, with a weighted genetic risk score (GRSGWS) showing an odds ratio of 1.36 for every standard deviation increase, indicating higher risk for individuals in the top 20%.
  • * Incorporating the GRSGWS with existing phenotypic risk factors slightly improved melanoma risk prediction, raising the C-statistic from 0.764 to 0.775.

We updated a field synopsis of genetic associations of cutaneous melanoma (CM) by systematically retrieving and combining data from all studies in the field published as of August 31, 2013. Data were available from 197 studies, which included 83,343 CM cases and 187,809 controls and reported on 1,126 polymorphisms in 289 different genes. Random-effects meta-analyses of 81 eligible polymorphisms evaluated in >4 data sets confirmed 20 single-nucleotide polymorphisms across 10 loci (TYR, AFG3L1P, CDK10, MYH7B, SLC45A2, MTAP, ATM, CLPTM1L, FTO, and CASP8) that have previously been published with genome-wide significant evidence for association (P<5 × 10(-8)) with CM risk, with certain variants possibly functioning as proxies of already tagged genes.

Fibrosis is a complex and multifactorial process, affecting the structure and compromising the function of several organs. Among those, renal fibrosis is an important pathological change, eventually leading to renal failure. Proteomic analysis of the renal parenchyma in the well-established rat model of unilateral ureteral obstruction (UUO model) suggested that transgelin was up-regulated during the development of fibrosis.

Background/aims: Activation of myofibroblasts occurs during kidney injury. Genomic and proteomic studies suggest that transgelin represents a protein that may be involved in renal injury. The purpose of this study was to estimate transgelin expression in the renal tissue of patients with glomerulonephritis.

Chronic kidney disease (CKD) is the end-point of a number of renal and systemic diseases. The high incidence and financial burden of CKD makes it imperative to diagnose CKD at early stages when therapeutic interventions are far more effective. A key component of CKD is the development of renal fibrosis.
