PURPOSE: To investigate the ability of anti-Mullerian hormone (AMH) to predict the step up of human menopausal gonadotropins (HMG) dose in women with polycystic ovarian syndrome (PCOS) undergoing IVF/ICSI cycles.

METHODS: AMH was drawn before ovulation induction in 976 PCOS women scheduled for IVF/ICSI. After all cycles ended, a receiver operating characteristic (ROC) curve analysis was done to investigate the ability of AMH to predict step up of the HMG.

RESULTS: The area under the curve (AUC) was 0.820 95%CI (0.792-0.848), and a cutoff value of 4.6 ng/ml (sensitivity 74%, specificity 82%) for AMH was taken (p < 0.01). Cases were divided into two groups retrospectively; group (A) (AMH ≤4.6 ng/ml), and group (B) (AMH >4.6 ng/ml). No difference in the mean age (p = 0.147); BMI (p = 0.411), basal FSH (p = 0.221), and starting dose (p = 0.195); however, the dose at which the first response occurred was higher in group (B) (p < 0.01). The total dose and number of days were higher in group (B) (both p < 0.01) irrespective of the PCOS subtype or androgen levels. Severe OHSS was also higher in group (B) (p = 0.026).

CONCLUSIONS: PCOS with AMH >4.6 ng/ml are resistant to HMG stimulation, require dose step up during ART cycles, and are at higher risk for severe OHSS.

BACKGROUND AND AIM: We aimed to evaluate the accuracy of readily available laboratory tests (ALT, AST, platelet count, AST to platelet ratio index: APRI) in predicting liver fibrosis in chronic hepatitis C, in comparison to the predictive accuracy obtained by liver biopsy. Pediatrics,

METHODS: One hundred and thirteen patients suffering from chronic hepatitis C (CHC) were included in this study. They included 76 children enrolled from the Pediatric Hepatology Unit and 37 adults enrolled from the Hepatology Unit of Tropical Medicine Department, Cairo University, Egypt. Fibrosis results obtained from liver biopsy were assigned a score from 0 to 4 score as per Metavir scoring. Results of serum ALT and AST levels were expressed as ratio of the upper limit of normal (ULN).

RESULTS: Of the pediatric patients, 28 (36.8%) showed no evidence of fibrosis on liver biopsy, 26 (34.2%) showed grade 1 fibrosis, and 22 (29%) had grade 2 fibrosis. Among the adult patients, 12 (32.4%) had grade 2 fibrosis and 25 patients (67.6%) had grades 3 to 4 fibrosis. There was a lack of correlation between the degree of fibrosis and AST levels, AST/ALT ratio, platelet count and APRI. The AUROC curve for predicting significant fibrosis was 0.5 for AST levels, 0.37 for AST/ALT ratio and 0.49 for APRI, in pediatric patients (p > 0.05). In adult patients the AUROC curve for predicting significant fibrosis was 0.59 for AST levels, 0.76 for AST/ALT ratio and 0.63 for APRI (p > 0.05).

CONCLUSION: Liver biopsy remains the gold standard to assess the extent of hepatic fibrosis in patients with CHC.

Background
The preferential accumulation of 5-aminolaevulinic acid (ALA)- induced protoporphyrin IX (PpIX) in neoplastic cells supports its potential use in the photodetection of epithelial tumours through porphyrin fluorescence.

Objective
To assess the validity of fluorescence diagnosis (FD) as an efficient pre-surgical in vivo imaging tool for defining the lateral boundaries of various types of basal cell carcinomas (BCCs).

Methods
The BCC tumour area was determined for 27 patients using FD digitalized imaging system, where the accumulation of PpIX in tumour tissue in relation to normal tissue was measured. Subsequently, BCCs were excised according to the complete area defined by FD using Mohs micrographic surgery (MMS).

Results
Of the 27 BCCs, the FD margin of the lesion coincided with the histopathological picture in 12 BCCs (44.44%). The mean value of accumulation factor (AF) was 2.7. Although 17 pigmented BCCs showed attenuated or absent fluorescence in the center, fluorescence at their periphery was used as a guide for excision, and statistically, the pigmentation of the BCCs showed no effect on the results of the FD efficacy (p = 1.0).

Conclusion
Fluorescence diagnosis of BCC may be beneficial as a guide to the safety margin needed before MMS. The safety margin is decided according to the FD tumour diameter in relation to the clinical tumour diameter.
