Factors affecting outcome of one-stage anterior hypospadias repair: analysis of 422 cases

The repair of hypospadias is among the most difficult problems in urology, as it demands the construction of a well-functioning urethra and a good cosmetic appearance. We performed a retrospective analysis of 422 cases subjected to one-stage anterior hypospadias repair between 1982 and 1999 in our clinic and investigated the effects of factors like degree of hypospadias, surgical technique, and the surgeon's experience on outcome. The operations used were MAGPI (91), urethral advancement (10), Mathieu (260), modified Allen-Spence (50), onlay island flap (5), and double-faced island flap (6) procedures. The early complication rate was 18%, while the final success rate following secondary interventions was 95%. The complications included fistula formation in 49 cases (12%), flap necrosis in 12 (3%), meatal problems in 12 (3%), residual chordee in 4 (1%), and urethral stricture in 1 (<1%). Complication rates were significantly higher if the meatus was proximal or there was severe chordee and in the first 6 years of the study. The flap procedures were associated with a higher complication rate. It is concluded that one-stage procedures are successful in the repair of anterior hypospadias in experienced hands with proper patient selection. Accepted: 21 March 2001     

Gynecomastia following chemotherapy for testicular cancer

A 22-year-old man received 4 cycles of bleomycin, etoposide and cisplatin combination chemotherapy for clinical stage IIA embryonal cell carcinoma of the right testis. The treatment resulted in complete remission. Five months following cessation of the chemotherapy first on the left and then 2 weeks later on the right side painful gynecomastia developed. His hormonal values are all normal with no evidence of recurrence of the cancer. Gynecomastia on both sides resolved in 8 months spontaneously without any treatment. He is still in clinical remission 14 months after completion of the chemotherapy. We should be aware that gynecomastia following cytotoxic chemotherapy in a young man does not necessarily mean the return of the cancer.     

Lipoma arborescens (diffuse articular lipomatosis)

Lipoma arborescens (LA) (diffuse articular lipomatosis, synovial lipomatosis, Hoffa disease) is a rare intra-articular lesion of unknown etiology. This article presents three patients who had LA, which was diagnosed in the knee in two patients and in the wrist of the third patient. Details of the clinical and histomorphological examination and treatment, in addition to a review of the literature, are discussed. The article concludes that in patients with a slow increase in painless swelling of the joints, unresolving articular pain with or without limited motion, or intermittent effusions following a minor trauma, LA should be considered in the differential diagnosis. It should be remembered that LA occurs in joints other than the knee, such as the elbow, shoulder, and wrist. Although recommended surgery involves arthrotomy and synovectomy, arthroscopic synovectomy may be a useful treatment modality, particularly in the larger joints as the recurrence rate is low.     

A neurosurgical view of anatomical evaluation of anterior C1–C2 for safer transoral odontoidectomy

An anatomical study for evaluation of anterior C1–C2. To provide essential anatomic data for safer transoral odontoidectomy. The surface dimensions of the atlas vertebra and the transoral approach for odontoidectomy have been described in detail. Anterior arcus of C1 must be drilled out to reach odontoid process for transoral odontoidectomy. The thickness of anterior ring of C1 has not been studied before. Sixty, dried adult atlas and 60 axis vertebrae and ten cadaveric craniocervical specimens were measured for the following: (1) bony drilling depth (BDD), the distance from the anterior wall of anterior ring of C1 to anterior wall of odontoid; (2) minimum drilling diameter (MDD), distance of minimum C1 anterior ring removal for odontoid resection on horizontal plane; (3) maximum bony drilling diameter (MBDD), distance of maximum C1 anterior ring removal for odontoid resection on horizontal plane. Lateral border of this diameter is limited by medial borders of the lateral mass; (4) the widest odontoid diameters (WOD) on coronal sections were measured. On 60 atlas and axis vertebrae, the BDD was 7.0 ± 1.2 mm on dry bones, the distance between the medial borders of the lateral mass (MBDD) was 16.1 ± 1.5 mm, and the WOD on coronal sections (WOD) was 9.8 ± 0.8 mm. On cadavers, the distance between the two edges of C1 anterior ring removal for odontoid resection (MDD) was 10.8 ± 1.1 mm and the WOD on coronal sections (WOD) was 10.1 ± 1.4 mm. An odontoid surgery through transoral approach is safe and feasible. A quantitative understanding of the anterior anatomy of C-1 and C-2 is necessary when considering transoral odontoid resection. In this study the authors define safe zones for anterior atlas and axis.     

Thrombotic thrombocytopenic purpura associated with multiple myeloma

Thrombotic thrombocytopenic purpura is a thrombotic microangiopathic disease. Associations with collagen vascular diseases, pregnancy, some drugs, surgical intervention, and infections are documented (known). Malignancy is also one of the known factors associated with thrombotic thrombocytopenic purpura. These malignancies are usually the disseminated solid organ tumors. Hematological malignancies constitute a rare association. Here, we present a patient with thrombotic thrombocytopenic purpura associated with multiple myeloma and discuss the pathogenesis. To our knowledge, this is the first case report of thrombotic thrombocytopenic purpura associated with multiple myeloma.     

Argon laser treatment of pterygium

The effectiveness of argon laser therapy on pterygium management as a primary modality and as adjunctive therapy to surgery was assessed. Twelve pterygia were surgically excised, 18 pterygia were treated with surgical excision followed by argon laser therapy, and 11 primary pterygia received argon laser alone. A statistically significant difference, was found between pretreatment and post-treatment sizes of pterygia in all groups. At 24-month follow-up, no pterygia in the laser group showed fibrovascular growth over 1 mm.     

Anti-Saccharomyces cerevisiae Antibodies in Acute Myocardial Infarction.

BACKGROUND: Elevated anti-Saccharomyces cerevisiae antibody (ASCA) immunoglobulin (IgG) and IgA levels were first described in the serum of Crohn disease patients and have increasingly been reported in other inflammatory diseases. The role of in situ and remote inflammation in atherosclerosis is a major area of interest. In this study, we compared ASCA IgG and IgA levels in acute myocardial infarction (AMI) and controls to investigate the possible role of ASCA in AMI. METHODS: Serum samples were obtained from 140 consecutive patients who presented to the emergency department with acute chest pain. AMI was diagnosed by electrocardiography and serial enzymes. Patients ruled out for acute coronary event were grouped as controls. ASCA IgA and IgG levels were determined using enzyme-linked immunosorbent assay. Groups were compared for statistically significant difference. RESULTS: ASCA IgG titers ranged between 0.1 and 31.0 RIU/mL (mean 4.92) in the AMI group and 0.1 and 6.0 (mean 0.84) in the controls. The groups were found to differ very significantly (p = .001). ASCA IgA titers ranged between 2.0 and 200.0 RIU/mL (mean 13.73) in the AMI group and 2.0 and 11.5 RIU/mL, (mean 4.25) in controls. The groups differed significantly (p = .32). AMI and controls were also analyzed for ASCA IgA and IgG positivity. Both groups differed significantly from controls (p = .013). CONCLUSION: Elevated ASCA IgA and IgG levels as well as ASCA positivity in the AMI might suggest use of ASCA as a marker for atherosclerotic plaque instability. It might also provide a link between inflammatory processes and increased cardiovascular risk. Further studies are needed on a Saccharomyces cerevisiae-based diet, related intestinal colonization, and associated inflammation, autoimmune disorders, and cardiovascular events.
