Ingested foreign bodies, although fairly common among children, can present in individuals of all age. Most common risk factors for such cases in adults include psychiatric illness, alcohol abuse and ill-fitting dentures. Most of the ingested foreign bodies pass through the gastrointestinal tract but intervention maybe required in case of impaction, obstruction or perforation.

Mycobacterium avium complex, a commonly seen infection in individuals with a compromised immune system, can also affect people who are immunocompetent. One particularly important manifestation is in elderly females with a competent immune system, involving the middle lobe and lingula lobe of the lung. This is known as Lady Windermere syndrome (LWS).

Article Synopsis
  • - Esophageal squamous cell carcinoma (ESCC) is the eighth most common cancer worldwide and has a high potential for spreading to other parts of the body.
  • - A rare case involving a 67-year-old man with a history of cervical esophagus SCC showed unusual metastasis to the patella, causing symptoms like knee pain, leukocytosis, and anemia.
  • - The case emphasizes the need for awareness of atypical metastatic sites in ESCC, advocating for a specialized, multidisciplinary approach to effectively manage such complex situations.

Article Synopsis
  • Pseudohypoparathyroidism (PHP) is a disorder where the body is resistant to parathyroid hormone, causing high PTH levels, low calcium, and high phosphate, leading to various health issues.
  • The most common subtype, PHP type 1a, causes symptoms like short stature and electrolyte imbalances, which can result in conditions like seizures or fractures.
  • A case study of a 22-year-old woman with PHP highlights her severe symptoms, diagnosis process, and treatment plan, including calcium and Vitamin D supplementation after managing her fractures.

In this work, we present a methodology to create an effective novel double-sided symmetric architecture of solid-state electrochromic devices. This principally new nonconventional configuration provides access to novel electrochromic systems that could be applicable for the creation of smart double-side signage, smart boards, nonemissive displays, and other smart interactive devices that change their color upon application of a voltage. The proposed configuration is based on the assembly of two identical electrochromic materials facing each other through an opaque optical separator.

Joubert syndrome is a rare neurological and developmental malfunction represented by decreased muscle tone, ataxia, and delayed developmental milestones. Joubert syndrome-related disorders, besides central nervous system, can involve other systems and thus can lead to multi-organ malfunction. We report a case of pure Joubert syndrome who presented with developmental delay, decreased muscle tone, and ataxia.
