Scoring system evaluation for orbital exenteration in patients with rhino-orbito-cerebral mucormycosis.

PURPOSE: To evaluate our patients with rhino-orbito-cerebral mucormycosis according to a new scoring system and to compare those who underwent orbital exenteration persuant to a new threshhold. METHODS: Mucormycosis is a fungal disease that can be of acute onset, aggressive, and angioinvasive. Aggressive surgical debridement, long-term systemic antifungal therapy, and treatment of underlying predisposing factors are essential to the treatment. However, orbital exenteration is a very difficult decision to make, particularly in patients with orbital involvement, because there is little information in the literature, resulting in limited support for making this aggressive surgical decision. In this study, our 43 cases of mucormycosis were evaluated in terms of orbital exenteration using a scoring system (including clinical signs and symptoms, ophthalmoscopic findings, and radiologic results) developed by Shah et al., which establishes indications for orbital exenteration in mucormycosis. RESULTS: According to our study, if the threshold score for exenteration is 19.0, the sensitivity was 100% and specificity was 97%, providing better results than the 23.0 threshold score determined by the reference study for exenteration. When these two score thresholds were compared, there was a statistically significant difference. CONCLUSION: We believe that this scoring system may be beneficial to use for orbital exenteration in patients with mucormycosis. Prospective studies in large case series are required to determine the most appropriate threshold score.

Sperm retrieval by microdissection testicular sperm extraction and intracytoplasmic sperm injection outcomes in nonobstructive azoospermic patients with Klinefelter syndrome.

Klinefelter syndrome is the most frequent chromosomal abnormality in patients with nonobstructive azoospermia. The development of advanced assisted reproductive techniques, such as testicular sperm extraction and intracytoplasmic sperm injection, has provided the possibility of biological fathering in nonobstructive azoospermic patients with Klinefelter syndrome. We aimed to evaluate our sperm retrieval rate by microdissection testicular sperm extraction and to analyse the intracytoplasmic sperm injection outcomes in these patients. Medical records of 110 nonobstructive azoospermic patients with Klinefelter syndrome were retrospectively reviewed. We found that the sperm retrieval rate by microdissection testicular sperm extraction is lower than published reports on other types of secretory azoospermia. The statistical analyses yielded that age, FSH and testosterone levels as predictive factors for successful sperm retrieval.

Sperm retrieval and live birth rates in presumed Sertoli-cell-only syndrome in testis biopsy: a single centre experience.

We aimed to investigate sperm retrieval rates (SRR) by testicular sperm extraction (TESE), factors affecting SRR, and fertilization rate (FR), implantation rate (IR), clinical pregnancy rate (CPR) and live birth rate (LBR) in patients with presumed Sertoli-cell-only syndrome in testis biopsy (SCOS). We retrospectively evaluated files of 134 patients with SCOS who underwent TESE. Group I were patients in whom spermatozoa were retrieved and Group II were patients in whom no spermatozoa could be retrieved. SRR, Follicle stimulating hormone (FSH), Luteinizing hormone (LH), and testosterone levels, and the volume of testicles were compared between groups. In addition, FR, IR, CPR and LBR were determined. Sperm retrieval was achieved in 37 (27.6%) patients (Group I), and the remaining 97 (72.4%) patients made Group II. There were no significant differences in age, infertility time, testicular volume, serum FSH, LH and testosterone levels between Groups I and II (p > 0.05). Intracytoplasmic sperm injection (ICSI) was performed in 36 patients. FR, IR, and CPR were 60.86 ± 23.03, 36.53 ± 41.78 and 51.3% respectively. Cycle and patient based LBRs were 37.8 and 45.1% respectively. SRR in SCOS is lower than patients with non-obstructive azoospermia (NOA) in general. No parameters to predict spermatozoa retrieval were determined. In patients with SCOS, ICSI achieves similar live birth rate to other patients with NOA.

Tuberculosis in patients with end-stage renal disease undergoing dialysis in an endemic region of Turkey.

The incidence of tuberculosis (TB) is high in end-stage renal disease (ESRD) patients undergoing dialysis. Diagnosis is difficult and delayed in this patient group owing to extrapulmonary involvement and nonspecific symptoms. Adverse effects of antituberculosis treatment are seen more frequently in these patients. We retrospectively evaluated the frequency and clinical progression of TB in 18 of 343 dialysis patients diagnosed with TB over a 5-year period at a university hospital in Adana, Turkey. Mean time between initiation of dialysis to diagnosis of TB was 19.5 +/- 26.1 months. Extrapulmonary TB was more frequent (77.8%) than pulmonary TB (22.2%). Diagnosis of TB was made based on clinical data in 1 patient, and microbiologically or pathologically in others. Antituberculosis treatment with 3 or 4 drugs was administered to patients for 6 to 12 months; second-line treatment was initiated in 1 patient infected with multidrug-resistant bacilli. One patient died owing to a cause other than TB; another was lost to follow-up. Adverse effects were hepatotoxicity in 3, optic neuritis in 1, and neuropsychiatric in 3 patients. A clinical response to therapy was achieved in all of the 16 patients who completed treatment. In conclusion, the incidence of TB and the frequency of extrapulmonary involvement are high in dialysis patients. Physicians must be alert to unusual presentations and localizations of the disease; TB must be strongly suspected in endemic regions. Owing to the greater frequency of adverse effects of treatment in these patients, they must be carefully observed during treatment.
