We describe here the case of a 23-year old woman with small cell carcinoma of the ovary of the hypercalcemic type (SCCOHT) with SMARC-A4 mutation who benefited from surgery in two steps leading to a total hysterectomy with bilateral salpingo-oophorectomy, omentectomy, pelvic and lombo-aortic lymph nodes dissection. She also received 6 courses of poly-chemotherapy after the surgery. A close follow-up was then performed by clinical examination every three months with determination of serum calcium and CA125 level as well as imaging with thoraco-abdominal CT scan. To date, the patient has a disease-free survival of more than 9 years. We also reviewed the literature on this topic and discuted the new diagnostic and prognostic genetic tool SMARC-A4 mutation.

Veterinary and agricultural surfactants are supposed to be inert additives, yet these substances commonly exert biological side-effects, in given cases synergistic with those of the active ingredients of these preparations. This is explicitly seen in altered toxicity of veterinary or pesticide formulations compared to their active ingredients alone. Neither the individual effects of these excipients, nor such combination effects are well-studied in toxicology, and therefore, possible toxicity consequences are occasionally not being considered at sufficient significance in the authorization, use and control of these substances. Risk assessment of these substances should cover all hazards they may represent, and corresponding levels of exposure. Surfactants used in veterinary and pesticide formulation enter the environment either by direct dispersion or by indirect release through excrement, leaching, sewage waters or sludge, and in turn, create potential exposure to a number of non-target organisms. Biochemical and (eco)toxicological hazards recently identified regarding certain agricultural surfactants include cytotoxicity (on cell lines of epithelial, neural and other tissues, as well as stem cells and tumor cells), endocrine disrupting effects, as well as aquatic ecotoxicity. This Mini Review summarizes toxicological effects identified in our studies in aquatic toxicity tests, in cell viability and cytotoxicity tests, in estrogenic activity assays, correlated with biochemical analysis of the surfactants and their decomposition. The conclusions are hoped to facilitate environmentally precautious revision of surfactants widely used in agriculture.

Cellular Angiofibroma is a rare benign mesenchymal tumor without gender preference. It is usually a small (<3cm), well-circumscribed, mostly asymptomatic and typically slow growing. Surgical removal of the mass with its capsule is the preferred treatment, not only helps guarantee complete excision and prevent its recurrence but also minimize blood loss. We present the case of a 76-year-old woman with a giant vulvar mass. 

Prostate specific membrane antigen, a type II transmembrane protein is an excellent target for the radionuclide therapy in advanced prostate cancer patients due to its high expression in the prostate cancer cells. We present the case of a 69-year old man with advanced metastatic castration resistant prostate cancer. In view of rising serum PSA levels despite hormonal and chemotherapy, we decided to perform a 68Ga-PSMA-HBED-CC PET/CT scan (prostate specific membrane antigen). It revealed intense radiotracer uptake in the prostate, lymph nodes and multiple skeletal sites. Five cycles of 177Lu-PSMA-DKFZ-617 radioligand therapy were administered in the patient followed by an intrim 68Ga-PSMA-HBED-CC PET/CT. Intrim 68Ga-PSMA-HBED-CC PET/CT scan demonstrated a near complete remission of disease with a corresponding decrease in the sPSA levels. During the follow-up duration of 12 months, the patient did not develop haematological, kidney and liver toxicity during the course of treatment and follow-up. 177Lu-PSMA-DKFZ-617 is a promising therapeutic option in metastatic castration resistant prostate cancer (mCRPC) patients.

NMDA receptor encephalitis is a rare disease first described in 2007. Anti-NMDA receptor encephalitis affects mostly young women as neoplasms, mostly ovarian teratomas, are the underlying cause. The disease is caused by antibodies binding to extracellular epitopes of neuronal cell-surface, which leads to an internalization of NMDA-receptors. The characteristic syndrome of patients with anti-NMDAR as well as its recovery follows a certain pattern. Treatment includes immunotherapy and removal of the immunologic trigger. This case report describes a young woman with anti-NMDA receptor encephalitis caused by an ovarian teratoma. 

The main goal of hyperthermia is to elevate the tumor temperature to kill tumor cells and improve local control. The usage of hyperthermia is combination with radiotherapy or chemotherapy. Hyperthermia is delivered in different types of cancers like breast cancer, melanoma and sarcoma. Breast cancer treatment enroll surgery, chemotherapy, radiotherapy and hormone therapy. Hyperthermia is given once or twice a week concomitantly with radiotherapy or chemotherapy. This short review will enlight the types, physics, and the results of hyperthermia especially in the management of breast cancer therapy.

Anoikis resistance (AR) is a favorable attribute exhibited by cancer cells for metastasis. Carcinoma associated Fibroblasts (CAFs) plays a crucial role in AR in various cancers. It was proved in array of studies in different cancers that there was definite interrelationship between CAFs and AR. But its role in OSCC is ambiguous. It is the need of the time to reveal the correlation of CAF and oral squamous cell carcinoma (OSCC) in relation with anoikis. Molecular pathways which affects the AR via CAFs in various cancers has been highlighted in this communication. Divulging the importance of CAF in cancer will aid in designing customized novel chemoprevention therapy and thus will help in enhancing the prognosis of patient in OSCC.

This report presents an adult patient suffering from sacroiliitis like low back pain, lumbosacral radiculopathy and elbow swelling. Multimodality imaging revealed multiple lytic bone lesions located in supra acetabular iliac bone, sacrum, and distal end of radius. Painful numerous lesions due to the extension to the articular surfaces are not expected for Brown tumors. Less than ten cases with multiple Brown tumor due to primary hyperparathyroidism has been reported. Although Brown tumors are mostly diagnosed incidentally, this case would awake the physicians about rheumatological symptoms in the presentation of Brown tumors. Since Brown tumors are non-touch bone lesions that are expected to regress after parathyroid adenoma removal, it is important to distinguish Brown tumors from the giant cell tumors.

Background: Breast cancer (BC) is one of the most prevalent malignancies. BC survivors have higher risk of second primary cancers than the general population. There is an increased interest in BC survivor management, including the prevention of these second cancers. The aim of this study was to assess the risk of gynaecological malignancy (GM) as second neoplasm among BC patients in our population. Methods: Patients with invasive BC diagnosed from 1980 to 2014 included in the Girona Cancer Registry were included. The incidence of second GM in these patients was compared to those in the general population. Second primary cancer was stated as a tumour diagnosed after 2 months from the BC diagnosis. Standardized incidence ratios (SIR) and absolute excess of risk (AER) were calculated. Results: 9,717 patients were diagnosed with invasive BC during this period, with a median age at diagnosis of 61 years, and a median follow-up of 7.9 years. 117 of them developed a second GM. By tumour type, the only statistically significant higher SIR was observed for corpus uteri cancer (SIR:2.28 95% CI 1.82-2.83; AER:6.43 95% CI 4.13-9.14). After reviewing the histology of the corpus uteri cancer cases, we found that 71.4% were type I (endometrioid adenocarcinoma), 15.5% type II (serous adenocarcinomas and clear cell carcinomas), 10.7% carcinosarcomas, 2.4% sarcomas and there were no unspecified malignant neoplasms. Conclusion: BC survivors have an increased risk of corpus uteri cancer, with an increase in unfavourable histologies compared to the general population. Lifelong primary and secondary prevention interventions should be recommended for these patients.

The RNA interference (RNAi) technique is a new modality for cancer therapy, and several candidates are being tested clinically. Nanotheranostics is a rapidly growing field combining disease diagnosis and therapy, which ultimately may add in the development of ‘personalized medicine’. Technologies on theranostic nanomedicines has been discussed. We designed and developed bioresponsive and fluorescent hyaluronic acid-iodixanol nanogels (HAI-NGs) for targeted X-ray computed tomography (CT) imaging and chemotherapy of MCF-7 human breast tumors. HAI-NGs were obtained with a small size of ca. 90 nm, bright green fluorescence and high serum stability from hyaluronic acid-cystamine-tetrazole and reductively degradable polyiodixanol-methacrylate via nanoprecipitation and a photo-click crosslinking reaction. This chapter presents an over view of the current status of translating the RNAi cancer therapeutics in the clinic, a brief description of the biological barriers in drug delivery, and the roles of imaging in aspects of administration route, systemic circulation, and cellular barriers for the clinical translation of RNAi cancer therapeutics, and with partial content for discussing the safety concerns. Finally, we focus on imaging-guided delivery of RNAi therapeutics in preclinical development, including the basic principles of different imaging modalities, and their advantages and limitations for biological imaging. With growing number of RNAi therapeutics entering the clinic, various imaging methods will play an important role in facilitating the translation of RNAi cancer therapeutics from bench to bedside.

We evaluated a total of 115 patients diagnosed with anal cancer, who were treated at our clinic from 1995 to 2012. Their average age was 61 years, most often were diagnosed in stages II and III, in most cases it was a squamous cell carcinoma located in the anal canal. The mean follow-up was 83 months (minimum 1 month and maximum 240 months). We combined external radiotherapy with boost of brachytherapy or boost of external radiotherapy and possibly a combination of both boosts. Half of the patients received concomitant chemotherapy. We specifically evaluated local tumor regression, overall survival and the impact to therapeutic effect of the chosen irradiation technique. Complete regression was achieved in 92 patients, partial regression in 21 patients. Overall survival, regardless of stage, was 80% 3-year, 74% 5-year and 67% 10-year. The age of patients, the size of their own primary tumor and the therapeutic method used had a statistically significant effect on survival - especially the importance of brachytherapy was irreplaceable.

Environmental electromagnetic fields are nowadays available in all environments today. These areas affect the biological system. Controlled interactions with elecrtomagnetic fields can have positive effects when unrestricted interactions have negative effects. Uncontrolled exposure to low-frequency electromagnetic fields can cause adverse effects such as signal transduction in cells and tissues, cell membrane structure, ion channels, molecular interactions, DNA damage. But contrary to controlled exposure, it positively affects tissues. The most obvious example of this is seen in the bone and cartilaginous tissue. Repairing fractures and damage in bone and cartilage. This has been shown in many studies. Below is a summary of the relevant information.

Background: Oral cancer accounts for 30% of all types of cancer in India. Surgery is the mainstay of treatment but due to the recent outbreak of COVID-19, there is a partial or complete disruption of health services in the country. The initial delay in the treatment was due to cancellations of planned surgeries as per government regulations and reduction in public transportation. In the latter half of the initial relaxation of the lockdown, we formulated our institutional protocol for the surgical treatment of oral cancer patients. On admission, all patients were kept in isolated wards followed by RT-PCR (Reverse Transcriptase-Polymerase Chain Reaction) testing on the same day. RT-PCR negative patients are subjected to HRCT Thorax (High-resolution Computer Tomography). This ensured the safety of health care workers, patients, and patient attendees. Keeping this in mind, we did an observational study on the role of HRCT in the pre-operative screening of asymptomatic oral cancer patients.  Materials and methods: Retrospective analysis of prospectively collected data of 150 patients was done. HRCT reporting was done by two experienced senior radiologists of the Department of Radiology at our hospital. Results: The number of patients under the CO-RADS 1 category was 121 and CO-RADS 2 category was 29, according to CO-RADS classification. The results of RT-PCR and HRCT were compared and there was a 100% positive correlation between RT-PCR and HRCT Thorax. Conclusion: Our study supported the use of HRCT Thorax as a diagnostic tool in pre-operative screening of oral cancer patients for COVID 19, particularly in RT-PCR negative cases.

Breast cancer is the most common cancer in women and is a major public health problem. It is divided into several subtypes, including triple negatives. The general objective of our study is to establish the profile and the management of patients with triple negative breast cancer over a period of 2 years, operated in our department. During our study period, triple-negative breast cancers accounted for 10% of our population. The most affected age group ranges from 50 to 60. The majority of patients in our sample are pauciparous. In the group of patients who received hormone therapy, it was mainly HRT for 4 to 6 years. 96.77% of patients consulted a health worker within 3 months of the discovery of the signs. Adenopathies are frequently present at the time of diagnosis. 93.54% of the cases have an invasive ductal carcinoma. Triple negative cancers are essentially poorly differentiated. Triple-negative cancer has a high rate of cell renewal. In our study, neoadjuvant chemotherapy is mostly indicated for triple-negative breast cancers ≥ 30 mm at diagnosis and a delayed lumpectomy is then performed in 23.52% of the patients. For tumors of < 30 mm size, a lumpectomy is performed immediately in 76.47% of the patients, followed by adjuvant chemotherapy. Mastectomy was performed in 45.16% of patients; it was mainly indicated in front of a large tumor size associated with a small breast volume, then multifocal breast tumors. Breast reconstruction was performed in 21.42%. Radiation therapy is indicated in the majority of patients, postoperatively. In our population, 11 patients were proposed to have an oncogenetic survey; it was mainly indicated based on the Manchester criteria in front of a young age and a family history of cancer. There are two BRCA 1 mutations, one BRCA 2 mutation, and one case of absence of mutation. The therapeutic intake in case of a mutation is directed towards a prophylactic bilateral mastectomy and adnexectomy, proposed at the age of 40. Two patients had presented triple negative recurrences of their already treated breast cancer; first case PDL1 positive PD-L1 ≥ 1% treated with immunotherapy combined with chemotherapy (atezolizumab/abraxane) while the second and second PDL1 negative treated with chemotherapy alone. Despite their low frequency, triple negative breast cancers represent a subgroup marked by pejorative characteristics, a reserved prognosis, with limited treatment options.

Nonsurgical fertility control is increasingly advocated as more cost-effective than surgical sterilization to manage stray animal populations in a different part of the world. An experimental study was conducted from December 2018 to April 2019 at Mekelle University to evaluate the effect of single bilateral intratesticular injection of cetrimide 2% in adult albino mice. A total of 20 clinically healthy albino mice selected based on their age and sex and were divided randomly into five groups and evaluation was conducted for 30 days after intratesticular injection of cetrimide solution 2% at the dose rate of 5, 10, 15 and 20 mg per testis and for control 0.1 mL normal saline per testis per 100 g body weight were given. All albino mice were evaluated for 30 days at a fixed interval. Change in body weight, scrotal width, sexual behavior, and fertility performance was also assessed. On day 30, all albino mice were sacrificed for histopathological study. Means  ±  Standard deviation of the mean, one-way, and a mixed model ANOVA (for repeated measures) was used to summarize the data, determine the effects of group and time on bodyweight and scrotal width. The significant increase in body weight (p - 0.001) and significant reduction of scrotal width (p - 0.001) were noted in all cetrimide treated in comparison to control groups. In addition, there was a significant (p < 0.05) reduction of scrotal width in albino mice after intratesticular injection of cetrimide on day 1, 10, 15, 20, 25, and 30 with respect to their experimental groups. Testicular histology revealed that there were multinucleated giant cells in seminiferous tubules, derangement of tubular architecture along with infiltration of leucocytes and appearance of fibrous tissue were seen on testicular sections at a dose rate of 15 and 20 mg. Similarly, a significant change in the sexual behavior of the treated males and no pregnancy was detected on female albino mice after 21 days post-coital at 10, 15, or 20 mg cetrimide-treated males. In conclusion, a single bilateral intratesticular injection of cetrimide 2% at a dose of 15 and 20 mg might provide an effective way of sterilization and may be considered as an alternative to surgical castration in male animals. Besides, further assessment should be done in the future to identify the mechanism of infertility.

Chagas disease is a public health problem in Latin America and its treatment is based on the use of benznidazole or nifurtimox compounds. Both present problems such as resistance, inefficiency in chronic infection and cytotoxic effects. New compounds such as posaconazole and amiodarone have been tested against T. cruzii and shown to be effective. In addition, new molecules have been synthesized and tested against T. cruzii. Because this protozoan is highly pathogenic, even with a number of cases of accidental laboratory infections, few laboratories located outside Latin America are authorized to work with its infective developmental stages. On the other hand, Trypanosoma dionisii is a non-pathogenic protozoan phylogenetically related to T. cruzii and that shares similar strategies to complete its life cycle in mammalian cells in vitro. Here, we describe a comparative analysis of the sensitivity of both parasites to benznidazole, posoconazole and amiodarone. We also analyzed the morphological effects of these compounds on both Trypanosoma species using electron microscopy. Our results show that T. dionisii is more sensitive to the compounds tested than T. cruzii. They also support a previous suggestion that it may constitute an excellent model for large scale screening of compounds against T. cruzii.

Ms X is a 34 year old para 1 woman who presented at 26+5 weeks’ gestation with fever, neurological symptoms and history of a viral illness. She was treated empirically for bacterial meningitis and transferred to a tertiary maternity hospital. Cerebrospinal fluid (CSF) polymerase chain reaction (PCR) was positive for enteroviral ribonucleic acid (RNA), confirming viral meningitis. Ms X improved clinically and was discharged after six days. A high index of suspicion is required for diagnosis of meningitis in pregnancy. Thorough history, examination and workup is vital for timely treatment. Prognosis in viral meningitis is excellent with no clear adverse fetal or neonatal outcomes.

Aim and objectives: Endometrial Window of Implantation (WOI) is open in the midsecretory phase wherein the markers of invasion and cell adhesion are manifested .The primary objective was to find out the predictive value of Endometrial thickness and profile as a prognostic factors for embryo transfers during ART. Materials and Methods: Endometrial thickness assessment was performed with grey scale ultrasound on the day of transfer just before thawing the embryos in patients undergoing Frozen embryo transfer cycle after endometrial preparation. Results: The mean age and standard deviation of study population was is 33.26+5.95.Out of 69 patients there was clinical pregnancy in 33 patients , miscarriage in 10 patients and ongoing pregnacy in 23 patients. So the implantation rate was 47.83% (33/69), early miscarriage rate (pregnancy ending before 12 weeks) was 14.49%(10/69) and the ongoing pregnancy rate was 33.33% (23/69). Endometrial thickness < 6 mm had comparable implantation rates but low ongoing pregnancy rates. Conclusion: The ultrasound morphological and vascular grading of endometrial thickness and vascularity is useful to synchronise Day 5 embryo transfer and window and implantation thereby minimizing the loss of good embryos in nonreceptive endometrium.

The human immune system consists of innate and adaptive immune responses which both provide protective immunity to microbial infection. The adaptive immune system consists of T and B cell which act as second line defense through production of neutralizing antibody by B cells and cytotoxic activity of CD8+ T cells. The CD4+ T-cell performs a central role in the immune responses. These cells also known as T4 or helper/inducer T lymphocytes recognize antigens presented by antigen presenting cells (APC) such as macrophages and monocytes. Once antigens such as bacteria and viruses are presented, CD4+ T lymphocytes orchestrate the body’s antigen-specific immune response by Coordinating B-lymphocyte production of antibodies to these antigens, producing cytokines and induction of cytotoxic T-lymphocytes. The paper was aimed to review the role of T-helper cells (CD4+ T cells) in human immune system against some microbial infections.

Isocitrate dehydrogenase (IDH) mutations are a common event in secondary glioblastoma multiforme and lower-grade adult infiltrative astrocytomas and independently confer a better prognosis [1,2]. These are highly conserved mutations during glioma progression and thus also a useful diagnostic marker amenable to modern molecular sequencing methods. These mutations can even be detected in sites distant from the primary tumour. We use an illustrative case of a patient with radiologically suspected recurrent astrocytoma and negative histology, but positive IDH-mutated tumour DNA detected within CSF. Our results demonstrated the usefulness of liquid biopsy for recurrent glioma within the context of equivocal or negative histopathological results, whilst also showing the ability to detect a de-novo IDH-2 mutation not present in the previous resection. Building on this ‘proof-of-concept’ result, we also take the opportunity to briefly review the current literature describing the various liquid biopsy substrates available to diagnose infiltrative gliomas, namely the study of circulating tumour DNA, circulating tumour cells, and extracellular vesicles. We outline the current challenges and prospects of liquid biopsies in these tumours and suggest that more studies are required to overcome these challenges and harness the potential benefits of liquid biopsies in guiding our management of gliomas
