Serum follicle-stimulating hormone, luteinizing hormone and testosterone were evaluated before, and 1, 3, 6, 9, 12 and 18 months after surgery.
Results: In 46XY males with nonobstructive azoospermia serum follicle-stimulating hormone during 18 months of followup, and luteinizing hormone 1 and 3 months postoperatively were significantly increased vs baseline. No significant
differences were observed in testosterone at any postoperative time point vs baseline. In men with Klinefelter’s syndrome who underwent sperm extraction mean testosterone significantly decreased an average of 30% to 35% vs baseline when assessed 1, 3, 6, 9 and 12 months postoperatively. It PX-478 returned to 75% of the preoperative level after 18 months. In Klinefelter’s syndrome cases no significant differences were observed
in follicle-stimulating hormone and luteinizing hormone at each postoperative time point.
Conclusions: Hormonal followup after microdissection testicular sperm extraction is recommended, particularly in patients with Klinefelter’s syndrome, to prevent the deleterious consequences of hypogonadism.”
“OBJECTIVE: A practical alternative for endonasal retraction is presented.
TECHNIQUE: Following 100 endoscopic endonasal procedures at the University of Pittsburgh, a simple alternative for gentle tissue retraction was introduced for endoscopic endonasal procedures: www.selleckchem.com/products/hmpl-504-azd6094-volitinib.html the “”Q-tip”" cotton swab. Its fine shape allows it to be inserted through one of the nostrils, sharing the space with the other instruments and the endoscope while preserving freedom of movement. Its long dimension allows it to reach deep areas while it is actively held by one of the surgeons, and its stiffness
allows more or less force to be applied in any direction. Its soft head permits gentle touch of retraction without causing injury to the noble neurovascular structures of the cranial base.
CONCLUSION: During endoscopic endonasal Methocarbamol surgery, the instruments are operated through the nostrils, which are restricted passages. Any retractor utilized has to be thin to share the space with the other instruments, long enough to reach the cranial base, and soft to avoid tissue damage. All of these characteristics were encountered in the “”Q-tip”" cotton swab.”
“OBJECTIVE: Microsurgical and endoscopic colloid cyst excision differ with regard to operative time length of hospital stay, and extent of resection.
METHODS: A retrospective review of a single surgeon’s microsurgical colloid cyst resection in 10 consecutive patients was performed. Cyst size, hydrocephalus, symptoms, operative time, postoperative stay, complications, and objective testing of memory, concentration, calculation, and attention (cognition), along with performance at job, were noted.
RESULTS: All 10 patients had complete excision, Mean cyst size, mean operative time, and median postoperative stay were 1.6 cm, 124 minutes, and 3.5 days respectively.
