Although pubertal gynecomastia is a common clinical presentation of adolescent males, prepubertal gynecomastia is uncommon and mostly idiopathic. However, pathological causes of prepubescent gynecomastia are encountered in clinical practice. This manuscript carries an important message to general pediatricians, to care about exclusion of pathological causes for every patient of prepubertal gynecomastia. We present four different patients with pathological gynecomastia. One of them revealed to be secondary to Sertoli cell tumor, while the second patient describes trauma as a rare cause of prepubertal true gynecomastia. To the best of our knowledge, this is the first time to report occupational trauma as a cause of true gynecomastia as confirmed by pathological specimen, in a prepubertal boy. The third patient presented with retro-areolar mass and bloody nipple discharge secondary to mammary duct ectasia and had favorable self-limited course. Hyperprolactinemia secondary to neglected congenital hypothyroidism was the cause beyond gynecomastia in the fourth patient and this cause has been reported only once in the literature.Conclusion Despite being rare, pathological causes of prepubertal gynecomastia are encountered in clinical practice, and full investigations including breast and testicular ultrasound are needed to exclude any pathology before diagnosing idiopathic gynecomastia. Repeated friction of the breast can lead to true gynecomastia not only to pseudogynecomastia as previously known. What is Known • It has been reported that trauma can cause pseudogynecomastia due to hematoma or fat necrosis. • Prepubertal gynecomastia is mostly idiopathic. What is New • Long-term breast trauma can cause true gynecomastia (adenosis). • Although being mostly idiopathic, pathological causes of prepubertal gynecomastia must be ruled out.
Elephant populations have greatly reduced mainly due to illegal poaching for their ivory. The trade in elephant products is protected by national laws and CITES agreements to prevent them from further decline. For instance, in Thailand, it is illegal to trade ivory from African elephants; however, the law allows possession of ivory from Asian elephants if permission has been obtained from the authorities. As such, means of enforcement of legislation are needed to classify the legal status of seized ivory products. Many DNA-based techniques have been previously reported for this purpose, although all have a limit of detection not suitable for extremely degraded samples.
We report an assay based on nested PCR followed by DGGE to confirm the legal or illegal status of seized ivory samples where it is assumed that the DNA will be highly degraded.
The assay was tested on aged ivory from which the assay was tested for reproducibility, specificity, and, importantly, sensitivity. Blind testing showed 100% identification accuracy. Correct assignment in all 304 samples tested was achieved including confirmation of the legal status of 227 highly degraded, aged ivories, thus underlining the high sensitivity of the assay.
The research output will be beneficial to analyze ivory casework samples in wildlife forensic laboratories.

Recent research in epilepsy patients confirms our understanding of epilepsy as a network disorder with widespread cortical compromise. Here, we aimed to investigate the neocortical laminar architecture in patients with focal cortical dysplasia (FCD) and periventricular nodular heterotopia (PNH) using clinically feasible 3 T MRI.
Eighteen epilepsy patients (FCD and PNH groups; n = 9 each) and age-matched healthy controls (n = 9) underwent T1 relaxation 3 T MRI, from which component probability T1 maps were utilized to extract sub-voxel composition of 6 T1 cortical layers. Seventy-eight cortical areas of the automated anatomical labeling atlas were divided into 1000 equal-volume sub-areas for better detection of cortical abnormalities, and logistic regressions were performed to compare FCD/PNH patients with healthy controls with the T1 layers composing each sub-area as regressors. selleck chemicals llc Statistical significance (p < 0.05) was determined by a likelihood-ratio test with correction for false discovery rate using cortical thinning) and diffusion abnormalities in various human epilepsy populations. Our study provides quantitative information of cortical laminar architecture in epilepsy patients that can be further targeted for study in functional and neuropathological studies.
Description of an improved technique of metaidoioplasty (clitoris penoid) and presentation of the follow-up of our own patients in comparison to results in the literature.
To reduce the complication rate of urethral strictures and urethrocutaneous fistula, the technique of metaidoioplasty was modified After elongation of clitoris by incision of chorda the urethra-including the clitoral hood-was reconstructed by distally, broadly based flap of labia minora. In aretrospective follow-up study over 4years, 75patients completed questionnaires to assess complications and satisfaction/quality of life and urinary symptoms (ICIQ-FLUTS questionnaire). The same questionnaires were completed by 25patients pre- and 3months postoperatively.
In the retrospective study, urethral strictures were detected in 1.4% of patients and urethrocutaneous fistulas in 9.4% of patients, which could be repaired in all cases. Furthermore, 39.5% of patients did not decide for phalloplasty and were satisfied with the appearance of the clitoris penoid in 85% and with their function in 88%. Asmall proportion of the patients developed urinary symptoms, which were mainly of minor severity and significantly dependent on age. In the prospective study, postoperative-versus preoperative-symptoms of urinary incontinence, nocturia, and obstructive micturition were slightly elevated, but mainly of minor severity.
The improved technique of metaidoioplasty using distally broadly based labia-minora flaps resulted in high satisfaction with low urethral complication rates.
