Demons-Meigs syndrome caused by a giant ovarian fibroma: A case report.

Demons-Meigs syndrome is a very rare entity. It combines a benign ovarian "fibroma-like" tumor with ascites and hydrothorax. The notion of benignancy is the key point.

A rare case of eosinophilic jejunitis: diagnosis and management strategies.

Eosinophilic gastroenteritis is a rare disease with an unknown cause, which can manifest independently or as part of a hyper-eosinophilic syndrome. The severity of the condition depends on the extent of eosinophilic infiltration and damage to the digestive tract. Diagnosis relies on histological examination, which reveals a significant presence of eosinophilic polymorphonuclear leukocytes in the digestive wall.

Investigation of a Circularly Polarized Metasurface Antenna for Hybrid Wireless Applications.

The increasing prevalence of the Internet of Things (IoT) as the primary networking infrastructure in a future society, driven by a strong focus on sustainability and data, is noteworthy. A significant concern associated with the widespread use of Internet of Things (IoT) devices is the insufficient availability of viable strategies for effectively sustaining their power supply and ensuring their uninterrupted functionality. The ability of RF energy-harvesting systems to externally replenish batteries serves as a primary driver for the development of these technologies.

An essential component of developing the THz imaging system for high-quality photos is choosing the right sensor.

A colic mesothelial cyst, mimicking an appendicular mucocoele in an elderly patient: A case report and a literature review.

Benign cystic mesothelioma is a very rare and uncommon lesion, first reported by Plaut in 1928. It affects young women of reproductive age. It is usually asymptomatic or has non-specific symptoms.

Atypical mid rectal localization of squamous cell carcinoma: A case report and literature review.

Introduction And Importance: Squamous cell carcinoma occurring in the rectum is a very rare malignancy. When encountered in the gastrointestinal tract, it usually involves the esophagus or the anal canal. The rare incidence of rectal squamous cell carcinomas has raised quite a few questions on the hypothetical etiologies and prognosis.

Role of Drone Technology Helping in Alleviating the COVID-19 Pandemic.

The COVID-19 pandemic, caused by a new coronavirus, has affected economic and social standards as governments and healthcare regulatory agencies throughout the world expressed worry and explored harsh preventative measures to counteract the disease's spread and intensity. Several academics and experts are primarily concerned with halting the continuous spread of the unique virus. Social separation, the closing of borders, the avoidance of big gatherings, contactless transit, and quarantine are important methods.

Thyroid metastasis revealing a lung adenocarcinoma: A case report and review of the literature.

Introduction: Metastatic lung adenocarcinoma in the thyroid is very rare. The clinical presentation and the radiological findings for metastasis carcinoma are nonspecific and do not allow the distinction between metastatic lung carcinoma and primary thyroid tumor.

Case Presentation: We report the case of a pulmonary papillary adenocarcinoma revealed by a thyroid metastasis in a 62-year-old and non-smoker patient with no history of cancer.

Hepatoid Adenocarcinoma of the Lung: .

Hepatoid adenocarcinoma is a rare type of extrahepatic adenocarcinoma with glandular and hepatocyte differenciation. The tumor can occur in many organs, generally in the stomach, the location of the lung being extremely rare. Despite poor prognosis and few effective treatment options, a timely and accurate histopathological diagnosis is key to optimal clinical management for long-term survival.

Blockchain Based Authentication and Cluster Head Selection Using DDR-LEACH in Internet of Sensor Things.

This paper proposes a blockchain-based node authentication model for the Internet of sensor things (IoST). The nodes in the network are authenticated based on their credentials to make the network free from malicious nodes. In IoST, sensor nodes gather the information from the environment and send it to the cluster heads (CHs) for additional processing.

Concurrent Angiomyolipoma and Clear Cell Renal Cell Carcinoma in the Same Kidney: A Rare Finding in a Patient without Tuberous Sclerosis.

Synchronous renal cell carcinomas (RCC) and angiomyolipomas (AML) occurring in the same kidney are rare. Cases in the setting of tuberous sclerosis (TS) have been reported in the literature. However, the association of these tumors in the same kidney without TS is even more rare.

Cystic mass of the right iliac fossa: don't forget about lymphatic malformation.

Lymphatic malformation or cystic lymphangioma is a benign tumour of the lymphatic vessels. It is more commonly reported among children and has polymorphic clinical presentations. The diagnosis is based on imaging but requires histological confirmation.

Leiomyosarcoma of the Renal Vein Mimicking a Primitive Renal Cell Carcinoma: Case Report of an Unusual Presentation.

Primary leiomyosarcomas (LMS) of vascular origin are rare tumors, and more than half of the cases arise in the inferior vena cava (IVC). Primary LMS of the renal vein are extremely rare tumors with only a few cases reported in the literature. Their diagnosis is made only by pathological features.

Primary Hodgkin lymphoma of the ulnar nerve: the first case report with review of the literature.

Hodgkin lymphoma is a lymphoid malignancy characterized by minority population of neoplastic cells (Reed-Sternberg cells and its variants) within a reactive inflammatory background. It encompasses two entities: classical HL (∼95% of cases) and nodular lymphocyte predominant HL (∼5% of cases). Primary lymphoma of peripheral nerves (PLPN) represent a very rare condition, since only 19 cases have been reported in the English literature to date, all of which are of a non-HL phenotype.

Retroperitoneal leiomyoma of gynecologic type: a case report and review of the litterature.

Retroperitoneal leiomyomas are rare benign tumors with smooth muscle differentiation, with only ~1001 cases reported in the English literature to date. Because of its scarcity and non-specific presentation, the preoperative diagnosis might be challenging. On histology, these neoplasms share the same macroscopic, morphological and phenotypic features with uterine leiomyoma; thus, they are referred to as leiomyoma of gynecologic type.

Application of machine intelligence technology in the detection of vaccines and medicines for SARS-CoV-2.

Researchers have found many similarities between the 2003 severe acute respiratory syndrome (SARS) virus and SARS-CoV-19 through existing data that reveal the SARS's cause. Artificial intelligence (AI) learning models can be created to predict drug structures that can be used to treat COVID-19. Despite the effectively demonstrated repurposed drugs, more repurposed drugs should be recognized.
