"Pseudo" (or secondary) achalasia is a rare entity that it isn't easily distinguishing from idiopathic achalasia by manometry, radiological examination and endoscopy. Usually a neoplastic process of the esophago-gastric region is associated with this clinical condition. However, it has been reported that other neoplastic processes may lead to the development of pseudoachalasia, such as mediastinal masses, gastrointestinal tumours (pancreas, liver, biliary tract and other organs) and non gastrointestinal malignancies. We present a case of pseudoachalasia in which the primary cause of the disease was not an esophago-gastric cancer.

Dengue hemorrhagic fever (DHF) typically presents with various bleeding manifestations such as epistaxis, gum bleeding, and gastrointestinal bleeding. However, spontaneous large muscle hematoma formation is a rare complication. This case report discusses a patient with DHF who developed bilateral psoas muscle hematomas, a very uncommon presentation.

Considering the increasing use of immune checkpoint inhibitors in cancer treatment, our aim is to report a rare cutaneous immune-related adverse event induced by PD-1 inhibitor pembrolizumab and provide a brief overview of pembrolizumab-induced subacute cutaneous lupus erythematosus (SCLE) cases in the literature. We report a 67-year-old woman with oropharyngeal squamous cell carcinoma who developed SCLE during treatment with pembrolizumab. After 18 weeks (sixth cycle) of pembrolizumab immunotherapy, a widespread pruritic erythematous rash evaluated as grade 3 immune-related adverse event appeared primarily on the patient's limbs.

Background: X-linked intellectual disability (XLID) is a genetically heterogeneous disorder that results in cognitive impairment and developmental delays. Mutations in the KDM5C gene have been identified as a causative factor in XLID. This study aimed to identify novel variants associated with XLID and to investigate the clinical and genetic characteristics of XLID patients with mutations in the KDM5C gene.

Background: Leber congenital amaurosis (LCA), the most severe form of inherited retinal dystrophy, is a rare, heterogeneous, genetic eye disease associated with severe congenital visual impairment. RPE65, one of the causative genes for LCA, encodes retinoid isomerohydrolase, an enzyme that plays a critical role in regenerating visual pigment in photoreceptor cells.
Methods: Exome sequencing (ES) was performed on a patient with suspected LCA.
