Introduction Chronic rhinosinusitis (CRS) not only affects the overlying mucosa but also involve the underlying sinus bone termed as osteitis. The role of osteitic bone in severity and persistence of disease has received little attention. Thus understanding of this can help in formulating better treatment plan for CRS. We conceived this study with an aim to assess correlation of osteitis with severity of disease and short term disease outcome by examining the various parameters concerned with CRS. Material and Methods This prospective cohort study included 40 participants as clinically diagnosed CRS cases and 20 participants as controls. Various pre and post-operative parameters concerning CRS were assessed like pre and post-operative Sino-Nasal Outcome Test (SNOT) 20 symptom score, Lund-Kennedy endoscopy and Lund Mackay CT scores, bone density / Hounsfield unit (HU), radiological bone thickness and histopathological mucosal and bone grading. Correlation between osteitis and all these parameters were analyzed. Results Osteitis / bone grade was found to have statistically significant, moderate and positive correlation with the preoperative Lund and Mackay CT score and mucosal grade. The osteitis / bone grade was found to be weakly and positively correlated to the Lund and Kennedy score and weakly but negatively correlated to change in SNOT- 20 values (both statistically insignificant). Conclusion There are high chances of harbouring severe osteitis underneath high grade mucosal disease in CRS. Preoperative Lund and Mackay CT score can serve as a surrogate marker for osteitis. Symptomatic severity of disease does not correlate with osteitis. Osteitis affects disease outcome negatively.

Surgical Menopause

Introduction. Patients with surgical menopause have a risk for osteopenic syndrome (OS). Menopausal hormone therapy (MHT) in combination with calcium and vitamin D promotes increase in bone mineral density (BMD). The expression level of vitamin D receptor in mononuclear fraction cells (MNFC) of blood can be considered as a predictive marker of effectiveness of OS therapy. Aim. To search a molecular predictive marker of the effectiveness of OS treatment. Materials and methods. The study included 100 women aged 4055 years with a duration of surgical menopause from 12 months to 6 years. The criterion for including patients in the study was the absence of contraindications to the use of MHT. The subject of the study was the determination of BMD by dual-energy X-ray absorptiometry, polymerase chain reaction diagnostics of the level of expression of vitamin D genes, estradiol and progesterone receptors, determination of 25-OH vitamin D in the blood. Results. Analysis of 12-month OS therapy effectiveness evaluated with a surrogate marker BMD. The increase in BMD up to 34% per year was treated as absence of negative dynamics, more than 4% per year as positive one. Significant effect of combination therapy compared with MHT on BMD in patients with surgical menopause with a low baseline level of BMD (due to hypovitaminosis D) is associated with the anti-inflammatory, bone-protective effect of vitamin D. In both groups of patients not responding; to the prescribed therapy we were able to conduct a comparative analysis of expression level of the target molecules in the MNFC before the start of treatment. The efficacy of MHT and combination therapy for BMD disorders is positively associated with the expression level of vitamin D receptors in MNFC before treatment. Therefore, the vitDR mRNA level is a potential predictive marker of the effectiveness of OS treatment. The expression levels of nuclear estradiol beta receptor and membrane receptor for progesterone in MNFC before treatment showed an upward trend in women responding to therapy. Conclusion. The expression level of the vitamin D receptor in MNFC of blood is significantly lower in the group of women with no/insufficient effect on 12-month combined therapy. This indicator can be considered as a predictive marker of the effectiveness of OS therapy.

Background: Silencing of several genes is critical for cancer therapy. These genes may be apoptotic gene, cell proliferation gene, DNA synthesis gene, etc. The two subunits of Ribonucleotide Reductase (RR), RRM1 and RRM2, are critical for DNA synthesis. Hence, targeting the blockage of DNA synthesis at tumor site can be a smart mode of cancer therapy. Specific targeting of blockage of RRM2 is done effectively by SiRNA. The drawbacks of siRNA delivery in the body include the poor uptake by all kinds of cells, questionable stability under physiological condition, non-target effect and ability to trigger the immune response. These obstacles may be overcome by target delivery of siRNA at the tumor site. This review presents a holistic overview regarding the role of RRM2 in controlling cancer progression. The nanoparticles are more effective due to specific characteristics like cell membrane penetration capacity, less toxicity, etc. RRM2 have been found to be elevated in different types of cancer and identified as the prognostic and predictive marker of the disease. Reductase RRM1 and RRM2 regulate the protein and gene expression of E2F, which is critical for protein expression and progression of cell cycle and cancer. The knockdown of RRM2 leads to apoptosis via Bcl2 in cancer. Both Bcl2 and E2F are critical in the progression of cancer, hence a gene that can affect both in regulating DNA replication is essential for cancer therapy. Aim: The aim of the review is to identify the related gene whose silencing may inhibit cancer progression. Conclusion: In this review, we illuminate the critical link between RRM-E2F, RRM-Bcl2, RRM-HDAC for the therapy of cancer. Altogether, this review presents an overview of all types of SiRNA targeted for cancer therapy with special emphasis on RRM2 for controlling the tumor progression.

Chronic rhinosinusitis is a common condition affecting 5–12% of the general population worldwide. In a limited number of cases, the disease is recalcitrant to medical and surgical interventions, causing a major impact on physical, social and emotional well-being and increasing pressure on healthcare systems. Biofilm formation and dysbiosis caused by Staphylococcus aureus and Pseudomonas aeruginosa play a role in the pathogenesis of recalcitrant chronic rhinosinusitis. In these cases, a promising treatment alternative is the application of bacteriophages, which are viruses that infect and lyse bacteria. In this review, we appraise the evidence for the use of bacteriophages in the treatment of recalcitrant chronic rhinosinusitis. Additionally, (dis)advantages of bacteriophages and considerations for implementation of phage therapy in otorhinolaryngology practice will be discussed.

Palatal Bone

A 44-year-old male patient was referred to the Egas Moniz Dental Clinic, with a previous history of failed bone regeneration, resulting in a reduced buccal-palatal bone thickness and aesthetic compromise of the gingival margin of the anterior maxilla. Since the use of autologous bone is considered the “gold-standard” in guided bone regeneration, the treatment plan consisted of an autologous mental graft into the maxilla, with a simultaneous guided bone regeneration with a xenograft and absorbable membrane. This allowed a predictable volumetric bone regeneration with low patient morbidity and posterior fixed rehabilitation.

The Relationship

The placenta is a transitory organ indispensable for normal fetal maturation and growth. Recognition of abnormal placental variants is important in clinical practice, and a broader understanding of the significance of placental variants would help clinicians better manage affected pregnancies. Increased thickness of the placenta is reported to be a nonspecific finding but it is associated with many maternal and fetal abnormalities, including preeclampsia and abnormal fetal growth. In this review, we address the questions regarding the characteristics of placenta thickness and the relationship between thickened placenta and poor pregnancy outcomes.
