Distal Humerus Physeal Separation: Diagnostic Challenges and Implications.

Distal humerus physeal separation is an uncommon and often misdiagnosed injury in infants and young children, frequently resulting in delayed treatment. We report three cases of distal humerus physeal separation that presented with different clinical scenarios with different management approaches. The first case describes a nine-month-old girl who was initially treated for presumed elbow cellulitis before presentation to our centre six weeks later.

α-ZnO Manipulated Growth of Ag Gird on AgNWs Enables High Conductive Flexible Electrode for Large-Area Monolithic Organic Photovoltaics.

The conductivity of AgNWs electrodes can be enhanced by incorporating Ag grids, thereby facilitating the development of large-area flexible organic solar cells (FOSCs). Ag grids from vacuum evaporation offer the advantages of simple film formation, adjustable thickness, and unique structure. However, the complex 3D multi-component structure of AgNWs electrodes will exacerbate the aggregation of large Ag particles, causing the device short circuits.

Systematic Localisation Based on History and Clinical Examination.

Localisation in neurology is an important step in determining the location of a neurological lesion based on history taking and clinical examination before confirmation with imaging. Lesions can vary from the cortical to the subcortical, brainstem, and spinal cord levels, in which every presentation and finding from the patient can provide a rough idea of where the pathology is located. A differential diagnosis can later be made according to the duration of the symptoms and the cumulative signs and symptoms presented.

Pulmonary hydatid cyst misdiagnosed as lung cancer.

Hydatid disease is endemic in Tunisia. Whereas uncomplicated pulmonary hydatid cysts are easily diagnosed on radiological findings, complicated and atypical forms may be misdiagnosed and confused with other pulmonary lesions, mainly lung malignancies. We report a case of a 47-year-old woman, who presented with a 3-month history of hemoptysis.

Perforated Meckel diverticulitis: Diagnostic challenges and surgical outcomes.

Meckel's diverticulum, a congenital anomaly of the omphalomesenteric duct, is a rare cause of acute abdomen and poses significant diagnostic challenges due to its variable presentation and complications such as perforation. We present the case of a 19-year-old male with a 24-hour history of right iliac fossa pain progressing to generalized abdominal tenderness. Laboratory results showed leukocytosis and elevated C-reactive protein, while CT imaging suggested pneumoperitoneum and an inflamed Meckel diverticulum.
