The role of preoperative lymphoscintigraphy in surgery planning for sentinel lymph node biopsy in malignant melanoma.
To evaluate four years of preoperative lymphoscintigraphy experience and the accuracy of sentinel lymph node biopsy in our institution in melanoma patients with various tumor thicknesses. An additional aim was to evaluate the recurrence rate related to pathohistological findings. ⋯ Preoperative lymphoscintigraphy is a sensitive, inexpensive and essential method for the identification of drainage basins, determination of the number and position of sentinel nodes and their location outside the usual nodal basins. Scintigraphic findings may lead to changes in surgical management due to the unpredictability of lymphatic drainage. The low incidence of regional disease recurrence in patients with tumor-negative sentinel nodes supports the use of preoperative lymphoscintigraphy and sentinel node biopsy as a safe and accurate procedure for staging the regional nodal basin in patients with malignant melanoma.

Case ReportsA woman with red eyes and hypokalemia: a case of acquired Gitelman syndrome.
Gitelman syndrome is a rare hereditary disorder of the thiazide-sensitive NaCl transporter in the distal renal tubular cells, but mimicking of such hereditary tubular disorders has been described in different autoimmune diseases (Sjögren syndrome, SLE, ...). A 62-year-old woman with painful red eyes and sicca syndrome presented at the ophthalmological department. The diagnostic evaluation identified a Sjögren syndrome with early endophthalmitis as the reason for the red eyes. ⋯ Together with the urine analysis, a rare case of an acquired Gitelman syndrome was diagnosed. Substitution with potassium and magnesium improved the initial symptoms of weakness, but renal electrolyte wasting persisted even after treatment of Sjögren syndrome. In patients with autoimmune disease, laboratory analysis of serum electrolytes should be performed because different acquired tubular disorders can lead to severe hypokalemia.
