Steroid-resistant nephrotic syndrome associated with Kimura's disease.

Kimura’s disease is a chronic inflammatory disease characterized by tumor-like lesions in the soft tissue and lymph nodes of head and neck area or parotid gland. It has a high frequency of an association with nephrotic syndrome. Reported cases of nephrotic syndrome and Kimura’s disease were mostly from adult patients with only 5 children mentioned. This study reports the case of a 15-year-old-boy who manifested with steroid-resistant nephrotic syndrome for 4 years. Pathological examination of the kidney revealed mild mesangial proliferation. Subsequently, he developed a soft-tissue mass in the parotid gland area. Histopathological investigation of the mass revealed eosinophilic infiltration together with plasma cells and mast cells which is a main characteristic of Kimura’s disease. The patient, however, continued to have nephrotic-range proteinuria after removing the subcutaneous mass.

Psychosocial functioning of children with systemic lupus erythematosus.

Aims:  Systemic lupus erythematosus (SLE) is a chronic illness in children. Involvement of multiple systems; the chronicity, as well as the treatment, has had great impact on children and their families. The objective of this study was to assess emotional and behavioural problems in childhood lupus during disease remission.

Successful treatment of neonatal pulmonary thrombosis in congenital nephrotic syndrome

A 21-year-old adult patient with Tetralogy of Fallot presented acutely unwell with a 3-month history of general malaise following dental treatment. Following initial complete repair, he subsequently underwent two right ventricular outflow tract reconstructions with conduits. On admission, transthoracic echocardiography and peripheral blood cultures were suggestive of streptococcal endocarditis. Sequential computed tomography pulmonary angiography demonstrated peripheral emboli with progressive central pulmonary artery filling defects suggestive of thrombi and potential vegetations (Fig 1a and b). Urgent surgery was performed for uncontrolled sepsis and increasing hypoxia. Peri-operative transesophageal echocardiogram confirmed previous findings (Fig 1c; Supplementary Video 1). Having resected the conduit, we performed a peripheral pulmonary embolectomy and resected an abundance of the infected material from the pulmonary arterial tree under low-flow hypothermia; we then proceeded with a jugular venous valved conduit (Contegra®, Medtronic Inc, Minneapolis, Minnesota, United States of America) replacement and tricuspid valve annuloplasty. He made a slow but steady recovery and was discharged home in good health
