Unveiling Langerhans cell histiocytosis presenting as hidradenitis suppurativa: A case report and systematic review.

Introduction And Importance: Langerhans cell histiocytosis (LCH) is a rare disorder characterized by the proliferation of abnormal Langerhans cells, often presenting with symptoms that mimic common dermatological conditions such as hidradenitis suppurativa (HS). Accurate diagnosis is essential because LCH can affect multiple organ systems and necessitates distinct therapeutic approaches.

Case Presentation: We report a rare case of a 39-year-old male with a 7-year history of diabetes insipidus (DI), who presented with polyuria, polydipsia, and enlarging purulent lesions in the axilla and groin.

Comparison of the Effect of Maternal Breast Milk Odor, Facilitated Tucking, and Nonnutritive Sucking Applied to Preterm Neonates During Heel Stick on Pain and Physiological Parameters: A Randomized Controlled Trial.

Preterm infants in the neonatal intensive care unit (NICU) frequently undergo painful procedures, which can lead to both short-term and long-term complications, including potential mortality. Effective pain management is crucial in this context. Although numerous studies have explored non-pharmacological pain relief methods for preterm infants, no research has simultaneously compared the effects of maternal breast milk odor, facilitated tucking, and nonnutritive sucking.

Antibacterial and anti-biofilm activities of gold-curcumin nanohybrids and its polydopamine form upon photo-sonotherapy of Staphylococcus aureus infected implants: In vitro and animal model studies.

Implant-related infections are among the major post-surgery problems, and treatment of these infections is challenging due to the formation of biofilms by microorganisms such as Staphylococcus aureus. Herein, a novel gold-curcumin nanohybrid (GCNH) was synthesized for the first time and characterized. GCNH had a band gap energy of 2.

A Hypothesis on the Function of High-Valent Fe in NiFe (Hydr)oxide in the Oxygen-Evolution Reaction.

This study investigated the dynamic changes in NiFe (hydr)oxide and identified the role of high-valent Fe in the oxygen-evolution reaction (OER) within alkaline media via in situ techniques. Several high-valent Fe ions were found to remain considerably stable in the absence of potential in NiFe (hydr)oxide, even 96 hours after the OER. For Ni hydroxide treated with Fe ions, where Fe sites are introduced onto the surface of Ni hydroxide, no Fe species were detected at the rate-determining step (RDS).

Identification and Manipulation of Spermatogonial Stem Cells with the Aim of Inducing Spermatogenesis in Vitro.

Assisted reproduction techniques for infertile men with non-obstructive azoospermia require a sufficient number of functional germ cells produced in vitro. Understanding the mechanisms that allow the resumption of spermatogenesis outside the testicular environment is crucial for fertility preservation in these patients. A review of the literature was conducted using databases such as PubMed, Scopus and Web of Science, with keywords including "spermatogonial stem cell," "germ cells," "male factor infertility," and "enrichment and propagation of SSCs in vitro.
