Pancake kidney with a single ureter, hydrometrocolpos, and imperforate anus: a set of uncommon malformations in a female adolescent.

An 11-year-old girl with a history of imperforate anus, urinary tract infection, and intermittent episodes of constipation presented with abdominal pain and nausea for 1 week. The x-rays revealed hydrometrocolpos and fused pelvic kidney with a single hydronephrotic ureter. The vaginal examination revealed a nonpermeable transverse vaginal septum.

[Treatment with sublingual desmopressin in two infants with hydranencephaly and central diabetes insipidus].

Central diabetes insipidus is a rare disease in children caused by a deficiency of vasopressin. Its main clinical manifestations are polyuria and polydipsia. Brain malformations are one of the main causes.

[Massive hydrothorax in a ease of hemolytic uremic syndrome: conservative treatment without interruption of peritoneal dialysis].

Unlabelled: The hydrothorax is a known but rare complication of acute and chronic peritoneal dialysis. Patients with hemolytic uremic syndrome seem to be more prone to this complication. Usually discontinuation of treatment is necessary due to the lack of resolution or recurrence of hydrothorax and transfer to hemodialysis, but some patients can continue dialysis with modification of technique and with resolution of hydrothorax.

[Posterior reversible encephalopathy in a girl with systemic lupus erythematosus: Report of a case].

Posterior reversible encephalopathy is a rare disease in children. Clinical manifestations include headache, seizures, visual disturbances and altered consciousness associated with typical magnetic resonance images of the nervous system. The syndrome usually manifests in patients with eclampsia, solid organ transplantation, haematologic, renal and autoimmune diseases among other less common causes and it is often triggered after a hypertensive crisis or use of immunosuppressive drugs.

[Acute kidney injury secondary to steroid-induced tumor lysis in an adolescent with acute lymphoblastic leukemia: role of urinary alkalinisation and peritoneal dialysis].

An adolescent with acute lymphoblastic leukemia developed an early and severe tumor lysis syndrome with acute kidney injury after a low and single dose of steroids. Renal dysfunction was attributed primarily to phosphate nephropathy with nephrocalcinosis due to extreme elevations of phosphate in blood. Urinary alkalinization probably contributed to this development.

[Pseudohypoaldosteronism type 1: an uncommon electrolyte emergency. Report of four cases].

Pseudohypoaldosteronism type 1 is a rare syndrome of resistance to aldosterone manifested by salt wasting, hyponatremia, hyperkalemia, hyperchloremic metabolic acidosis, and hiperreninemic hyperaldosteronism. The syndrome may be genetic, secondary to uropathies and urinary tract infection among other causes or it may occur sporadically. The salt wasting may be systemic and severe or localized to the kidney usually with better prognosis.

[Urinary extravasation post blunt abdominal trauma. Is it possible an early diagnosis? Report of two cases].

An injury to the upper urinary tract with urinary extravasation caused by blunt abdominal trauma is uncommon and often unrecognized in an initial evaluation. A late diagnosis of this injury significantly increases morbidity. Two cases are discussed, one with avulsion of right upper ureter and the other one with parenchymal and right renal pelvis laceration with delayed diagnosis and severe complications subsequent to a direct blunt abdominal trauma.

[Purpura fulminans, cerebral infarcts and multiorganic dysfunction due to hantavirus infection. Review and case report].

Multiorganic failure is a rare manifestation of hantavirus infection but it should be included among differential diagnoses of multiorganic failure in the pediatric age. Currently, there is no effective therapy for this infection. A high suspicion index and early referral to a pediatric intensive care unit with extracorporeal membrane oxygenation may lead to a favourable impact in the outcome.
