Pretibial Myxedema Presenting as Severe Elephantiasis.

Elephantiasis is a symptom characterized by the thickening of the skin and underlying tissues in the legs. Pretibial myxedema (PTM) is a non-frequent manifestation of autoimmune thyroiditis, particularly Graves' disease. Lesions of myxedema occur most commonly on the pretibial surfaces, also develop at sites of previous injury or scars and other areas. A 49-year-old male presented with severe elephantiasis on the both pretibial areas, dorsum of the feet, ankles and toes. Twenty years previously, he had received radioactive iodine treatment for thyrotoxicosis. Laboratory tests showed that the patient's thyroid function was normal, but the level of thyroid stimulating hormone (TSH) receptor antibodies was very high (>40 IU/L). The biopsy confirmed PTM. Interestingly, the connective tissue was stained with the TSH receptor antibodies in the deep dermis. Elephantiasic PTM is a severe form of the myxedema and there is few reported case. We report a rare case of PTM with appearance of severe elephantiasis.

Acute Urinary Retention due to Aseptic Meningitis: Meningitis-Retention Syndrome.

Acute urinary retention in aseptic meningitis is rarely encountered, and the diagnosis of aseptic meningitis may be less than straightforward, because its symptoms and neurological signs are occasionally mild or absent. We report a case in which acute urinary retention provided an appropriate indication for the diagnosis of aseptic meningitis as the cause of an undiagnosed fever.

Holmium laser enucleation of the prostate for benign prostatic hyperplasia: effectiveness, safety, and overcoming of the learning curve.

PURPOSE: To examine the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for the surgical treatment of benign prostatic hyperplasia and to estimate the time to overcome the learning curve. MATERIALS AND METHODS: From May 2008 to October 2009, 164 consecutive patients treated with HoLEP were enrolled in this study. International Prostate Symptom Score (IPSS), peak urinary flow rate (Qmax), and postvoid residual urine (PVR) were documented preoperatively and at 6 weeks and 3, 6, 12, and 18 months postoperatively. The 164 study subjects were divided into 3 groups (group 1 the first 50 patients treated, group 2 the second 50, and group 3 the third 64), and perioperative data and complications were analyzed in these groups to determine the learning curve. In addition, the inverse and upward techniques were compared in terms of the effects and the stability of morcellation. RESULTS: The mean patient age was 69 years, and the average operation time was 62 minutes (range, 20-208 minutes). Mean prostate volume was 54.2 ml and mean resected tissue weight was 18.6 g. Postoperatively, IPSS and PVR decreased and Qmax increased significantly. Postoperative complications were transient incontinence (8.5%), urinary retention (4.3%), hematuria (3.0%), urinary tract infection (1.2%), and urethral stricture (0.6%), and intraoperative complications were minor capsular perforation (4%) and bladder injury (8%). CONCLUSIONS: HoLEP was found to be effective and safe regardless of prostate size. We recommend that a systematic educational program be established to reduce the learning curve.
