Effects of coasting on the outcome of intracytoplasmic sperm injection-embryo transfer cycles

OBJECTIVES: To determine the effects of 'coasting' on the outcome of controlled ovarian hyperstimulation (COH) and intracytoplasmic sperm injection-embryo transfer (ICSI-ET). DESIGN: Retrospective study. SETTING: IVF Centre, Ozel Ege Tup Bebek Merkezi, Izmir, Turkey. SAMPLE: Twenty-six coasted and 52 non-coasted COH and ICSI-ET patients were enrolled in this retrospective study. METHODS: Coasted patients were enrolled consecutively during the study period, and two non-coasted controls were selected from our database for each coasted patient. Coasting was decided when serum oestradiol level was > or = 4000 pg/mL. Groups were compared using chi2 and Mann-Whitney U-tests for statistical analysis. MAIN OUTCOME MEASURES: Number of oocytes collected, metaphase II (MII) oocytes and cleaving embryos, the fertilisation rate and clinical pregnancy rate were the main outcome measures. RESULTS: Number of oocytes collected, number of MII oocytes, number of cleaving embryos, fertilisation rate and clinical pregnancy rate for the coasted and non-coasted groups were 15.5 +/- 5.2 and 14.0 +/- 7.1, 9.7 +/- 4.8 and 9.3 +/- 3.9, 6.8 +/- 3.9 and 5.8 +/- 3.1, 0.85 +/- 0.18 and 0.78 +/- 0.18, 13/26 and 24/52, respectively; these differences were not statistically significant. None of the patients in the coasted group were hospitalised for signs or findings of severe ovarian hyperstimulation syndrome. CONCLUSIONS: Coasting does not adversely affect the number and the function of mature oocytes and the clinical pregnancy rate.     

Fibrocystic disease of vulvar ectopic breast tissue. Case report and review of the literature

INTRODUCTION: Mammary glands located in the vulvar region have been named as ectopic breast tissue or anogenital mammary glands by different authors. Literature on pathologies of ectopic breast tissue located in the vulvar region is rare. Most of the reports are about the malignancies arising from this ectopic tissue. CASE REPORT: We report a case of fibrocystic disease of the mammary glands in the vulva in a 25-year-old pregnant woman. Her disease was exaggerated during pregnancy. CONCLUSION: Ectopic breast tissue in the vulva is a rare entity and fibrocystic disease of this tissue has rarely been reported in the English literature.     

Morphometry of the anterior third ventricle region as a guide for the transcallosal-interforniceal approach

The transcallosal-interforniceal approach is the most appropriate approach to localize and totally remove space-occupying lesions around the anterior third ventricle region such as craniopharyngiomas and gliomas. This study examined the microsurgical anatomy of the normal anterior third ventricle region in 81 adult cadaver hemispheres. The central sulcus was identified and surface landmarks determined as the points 5 cm (P5) and 7 cm anterior to the central sulcus (P7). The distances between P5 and P7 and the upper margin of the interventricular foramen, which delineate the surgical corridor chosen to avoid disturbance of important neural structures, were 46.26-60.96 (54.09 +/- 3.35) mm and 48.00-62.00 (54.94 +/- 3.09) mm, respectively. The distances between the upper margin of the hemisphere and the cingulate sulcus, especially important for avoiding damage to the cingulate gyrus and other mesiolimbic structures, were 13.54-30.00 (21.28 +/- 3.89) mm and 12.22-29.52 (21.12 +/- 3.90) mm at the level of P5 and P7. The distances between the upper margin of the hemisphere and the callosal cistern containing the pericallosal artery were 28.34-40.50 (33.94 +/- 2.84) mm and 28.16-40.26 (33.50 +/- 2.61) mm, respectively. Normative morphometric data of the structures involved in the surgical procedure are necessary for planning and performance of the transcallosal-interforniceal approaches. This study of a large series of specimens shows that these measurements have large individual variations.     

Complications and outcome in left-sided endocarditis in children

We retrospectively assessed the clinical course and outcome of left-sided endocarditis in pediatric patients to find out the prognostic significance of the presence and size of echocardiographically detected vegetations. Among the children admitted to our institution with endocarditis between January 1987 and October 1999, 16 patients (mean age 9.03 +/- 4.95 years) who met the Duke criteria for the diagnosis of infective endocarditis (IE) were included in this study. Rheumatic valvular disease was the most frequent underlying heart disease (10 patients: 62.5%). Five patients were operated at a mean of 13.9 months before endocarditis, and all had residual defects. Vegetation was detected in 11 cases (69%). Ten patients had major complications (within 2 weeks in 6 patients). Three patients developed congestive heart failure (CHF), six had intracranial and one had lower extremity emboli. Among them four were operated because of complications (CHF: 3 cases, intracranial emboli: 1 case). All the operated cases are doing well. The association between intracranial embolic events and echocardiographically detected vegetations was determined by calculating specificity (40%), sensitivity (100%), positive predictive value (50%), and negative predictive value (100%). No intracranial embolism occurred in patients without vegetations. All vegetations were < or = 6 mm in patients with systemic embolism. There were four deaths, three of which were because of intracranial embolism. This study suggests that intracranial emboli have a major risk of mortality in left-sided endocarditis. The larger size of the vegetation is not a predictor of complications; furthermore, the absence of vegetations predicts that the patient is safe from embolic events. Therefore all patients with left-sided IE should be considered for earlier surgical intervention.     

Protective effects of MESNA (2-mercaptoethane sulphonate) against acetaminophen-induced hepatorenal oxidative damage in mice

Acetaminophen, a widely used analgesic and antipyretic, is known to cause hepatic and renal injury in humans and experimental animals when administered in high doses. It was reported that these toxic effects of acetaminophen are due to oxidative reactions that take place during its metabolism. In this study we aimed to investigate the possible beneficial effect of 2-mercaptoethane sulphonate (MESNA), an antioxidant agent, against acetaminophen toxicity in mice. Balb-c mice were injected i.p. with: vehicle (the control group); a single dose of 150 mg kg(-1) MESNA (MES group); a single dose of 900 mg kg(-1) i.p. acetaminophen (AA4h and AA24h groups); and MESNA, at a dose of 150 mg kg(-1) after acetaminophen injection (AA4h-MES and AA24h-MES groups). The MESNA injection was repeated once more 12 h after the first injection in the AA24h-MES group. Blood urea nitrogen, serum creatinine, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in blood and glutathione (GSH) and malondialdehyde (MDA) levels, myeloperoxidase (MPO) activity and collagen contents in liver and kidney tissues were measured. Tissues also were examined microscopically. Blood urea nitrogen and serum creatinine, which were increased significantly (P < 0.001) following acetaminophen treatment were decreased significantly (P < 0.05-0.001) after treatment with MESNA. The ALT and AST levels were also increased significantly (P < 0.001) after acetaminophen treatment but were not reduced with MESNA. Acetaminophen treatment caused a significant (P < 0.05-0.001) decrease in GSH levels whereas MDA levels and MPO activity were increased in both tissues. These changes were reversed by MESNA treatment. Collagen contents of the liver and kidney tissues were increased by acetaminophen treatment (P < 0.001) and reversed back to the control levels with MESNA. Our results imply that acetaminophen causes oxidative damage in hepatic and renal tissues and that MESNA, via its antioxidant effects, protects these tissues. Therefore, its therapeutic role as a 'tissue injury-limiting agent' must be elucidated further in drug-induced oxidative damage.     

Comparison of ephedrine and ketamine in prevention of injection pain and hypotension due to propofol induction

BACKGROUND AND OBJECTIVE: This prospective, double-blind, randomized, placebo-controlled study compares the effects of ephedrine and ketamine on injection pain, and hypotension from propofol. METHODS: After obtaining the approval of the Ethics Committee, 75 patients (ASA I-II) scheduled for elective operations with general anaesthesia were divided into three groups. Saline 2 mL (Group S, n = 25), ketamine 0.5 mg kg(-1) (Group K, n = 25) or ephedrine 70 microg kg(-1) (Group E, n = 25) were administered over 5 s after tourniquet application. After releasing the tourniquet, propofol 2 mg kg(-1) was injected in 30 s. Pain was evaluated on a numerical scale (0-10) where 0 represented no pain and 10 the most severe pain possible. Systolic, diastolic blood pressures and heart rates were recorded preoperatively, 1 min after propofol injection, before intubation and 1, 2 and 3 min after intubation in all patients. RESULTS: The incidences of pain in Groups S, E and K were similar (84%, 80% and 72%, respectively). The mean pain score in Group K (2.1, SD 3.1) was significantly lower than those of Groups S and E (4.9, SD 2.6 and 4.6, SD, 3.3, respectively) (P < 0.05). The systolic and diastolic blood pressure values in Group K (120 +/- 27 mmHg) and Group E (123 +/- 21 mmHg) before intubation were significantly higher than that of Group S (104 +/- 25 mmHg) (P < 0.05). There was no significant difference between the mean heart rate values of the groups. CONCLUSIONS: Low dose ketamine or ephedrine pretreatment may prevent hypotension due to propofol induction. Despite the reduction in injection pain intensity after ketamine, the study drugs were found to be ineffective in lowering the injection pain incidence.     

Evaluation of a local anaesthesia regimen using a subphrenic catheter after gynaecological laparoscopy

BACKGROUND AND OBJECTIVE: The purpose of intraperitoneal local anaesthetic administration is to block visceral nociceptive conduction and to provide an additional route of analgesia. The present study evaluates the effects of sequential injections of bupivacaine on postoperative pain through a subphrenic catheter. METHODS: In this double-blinded controlled study, patients scheduled for gynaecological laparoscopy were randomly divided into two groups. One group received 20 mL of saline with 1:200000 epinephrine through a subphrenic catheter before the incision closure and at 4-hourly intervals for the first postoperative 20 h. The second group received 20 mL of bupivacaine 0.125% with 1:200000 epinephrine at the same injection times. Postoperative pain scores and consumption of analgesics were compared. RESULTS: There were no statistical differences in pain scores at rest or incidence of shoulder pain between the two groups, but the patients of the bupivacaine group reported lower pain scores on coughing only in the first hour postoperatively (P = 0.007). Although the patients consumed comparable amounts of metamizole and ondansetron, the number of patients requiring supplemental meperidine and flurbiprofen in the bupivacaine group were significantly lower than in the saline group (P < 0.05). CONCLUSIONS: This study demonstrates that intraperitoneal bupivacaine may reduce pain on coughing in the early postoperative period and the consumption of analgesics postoperatively. The subphrenic catheter technique had no impact upon pain at rest and shoulder-tip pain after gynaecological laparoscopy.     

Validation of 2001 Partin tables in Turkey: a multicenter study

OBJECTIVE: Although Partin tables were developed in United States to predict the stage of prostate cancer preoperatively, they are used by many clinics throughout the world assuming that these figures apply to their population as well. However the predictive value of current Partin tables, which was updated in 2001, has not been validated in most of the countries as well as in Turkey. Therefore, we evaluated the validity of 2001 Partin tables, for the ability to predict the pathological stage in Turkish patients. PATIENTS AND METHODS: The clinical and pathological findings of 1043 patients who have had radical prostatectomy were assessed. Serum PSA values, clinical stage, biopsy Gleason score and the pathological features of the radical prostatectomy specimens were collected from each clinic and evaluated. The predictive value of Partin nomogram and pathological findings of prostatectomy specimens were compared and analyzed according to Receiver Operating Characteristics (ROC) analysis. RESULTS: Median age of the patients was 60 (45-74). In the presented study, percentage of patients with clinical stage T1c was 43%. Patients with Gleason score of 2-4 in biopsy constituted 23.4% of the study group. In the present study, the ratio of the patients with serum PSA higher than 10 ng/ml was 39.6%. Organ confined disease, seminal vesicle involvement, lymph node metastases ratios were 64.7%, 10.3%, 1.8% respectively. Area Under Curve (AUC) values for organ confined disease, seminal vesicle involvement and lymph node involvement were calculated as 0.665, 0.733 and 0.759 respectively. CONCLUSION: It appears that Partin tables have a reasonable predictive value for the final pathological features like organ confined disease, seminal vesicle and lymph node involvement in Turkish patients. This multicenter study showed that current Partin tables could also be used in Turkish patients with comparable accuracy.
