BACKGROUND: The term balanitis includes a variety of inflammatory skin diseases involving the glans penis whose clinical diagnosis may be challenging. A biopsy is often required to obtain a definitive diagnosis, although it is barely accepted by patients. Reflectance confocal microscopy (RCM), that provides a real-time, en face imaging of the epidermis and upper dermis, is currently utilized for the diagnosis of some neoplastic and inflammatory skin diseases. The aim of this study was to analyze the RCM handheld findings of some common balanitis and to correlate them with dermatoscopy and histopathological features...

BACKGROUND: Self-reported male circumcision (MC) status is widely used to estimate community prevalence of circumcision, although its accuracy varies in different settings depending on the extent of misreporting. Despite this challenge, self-reported MC status remains essential because it is the most feasible method of collecting MC status data in community surveys. Therefore, its accuracy is an important determinant of the reliability of MC prevalence estimates based on such surveys...

REVIEW
Jean Gabriel Previnaire
The BCR consists of the contraction of the bulbocavernosus muscle in response to squeezing the glans penis or clitoris, and is mediated through the pudendal nerve. In case of a complete lesion, the presence of BCR is indicative of intact S2-S4 spinal reflex arcs and loss of supraspinal inhibition, determining an upper motor neuron (UMN) lesion, its absence a lower motor neuron (LMN) lesion. The BCR further helps distinguish conus medullaris from cauda equina syndromes. Sensory or motor function in the most caudal sacral segments, not BCR, defines the sacral sparing as part of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI)...

Metastases to the penis are rare, but can have severe consequences. The aim of this study was to systematically review the literature in order to gain more information on the presentation and prognosis of this metastatic disease. We reviewed the literature relating to all case reports, series and reviews about penile metastasis, from 2003 to 2013, through a Medline search. We identified 63 articles and 69 patients. Metastases were located on the root (38.8%), the shaft (38.8%) or the glans (22.2%) of the penis...

We describe a new experimental technique that allows for soft x-ray spectroscopy studies (∼100-1000 eV) of high pressure liquid (∼100 bars). We achieve this through a liquid cell with a 100 nm-thick Si3N4 membrane window, which is sandwiched by two identical O-rings for vacuum sealing. The thin Si3N4 membrane allows soft x-rays to penetrate, while separating the high-pressure liquid under investigation from the vacuum required for soft x-ray transmission and detection. The burst pressure of the Si3N4 membrane increases with decreasing size and more specifically is inversely proportional to the side length of the square window...

We analyzed the Fe 3d electronic structure in LiFePO4/FePO4 (LFP/FP) nanowire with a high cyclability by using soft X-ray emission spectroscopy (XES) combined with configuration-interaction full-multiplet (CIFM) calculation. The ex situ Fe L2,3-edge resonant XES (RXES) spectra for the LFP and FP are ascribed to oxidation states of Fe2+ and Fe3+, respectively. CIFM calculations for Fe2+ and Fe3+ states reproduced the Fe L3 RXES spectra for LFP and FP, respectively. In the calculations for both states, the charge-transfer energy was considerably larger than those for typical iron oxides, indicating very little electron transfer from the O 2p to Fe 3d orbitals and a weak hybridization on the Fe-O bond during the charge-discharge reactions...

We investigated the x-ray absorption spectroscopy (XAS) fingerprint of EMImTFSI ionic liquid (IL) and its fragmentation products created by x-ray irradiation. To accomplish this, we used an open geometry where an IL droplet is directly exposed in the vacuum chamber, and an enclosed geometry where the IL is confined in a cell covered by an x-ray transparent membrane. In the open geometry, the XAS signature was stable and consistent with experimental and theoretical spectra reported in the literature. In contrast, when the IL is enclosed, its XAS evolved continuously under x-ray illumination due to accumulation of volatile fragmentation products inside the closed cell, while they evaporate in the open geometry...

Disseminated fusariosis (DF) is a rare life threatening fungal infection in immunocompromised hosts. We herein report a case of a fatal DF mimicking varicella zoster virus (VZV) infection that was emerged from a localized genital infection during cord blood transplantation (CBT) in a patient with severe aplastic anemia (SAA). The patient developed an ulcer following small painful vesicles mimics herpes simplex virus infection (HSV) on the glans penis before CBT, but a Fusarium species was identified. Despite administration of voriconazole, liposomal amphotericin B and granulocyte transfusion, the lesion was extended to extensive skin looked like VZV infection and the patients died after CBT...

Noninfectious penile lesions are classified by clinical presentation as papulosquamous (e.g., psoriasis), inflammatory (e.g., lichen sclerosus, lichen nitidus, lichen planus), vascular (e.g., angiokeratomas), or neoplastic (e.g., carcinoma in situ, invasive squamous cell carcinoma). Psoriasis presents as red or salmon-colored plaques with overlying silvery scales, often with extragenital cutaneous lesions. Lichen sclerosus presents as a phimotic, hypopigmented prepuce or glans penis with a cellophane-like texture...

Bisphenol-A(BPA) is a member of alkylphenol family, and shows adverse effects including reduced fertility, reproductive tract abnormalities, metabolic disorder, cancer induction, neurotoxicity and immunotoxicity. In the present study, we conducted Hershberger assay to evaluate whether the two candidates to replace BPA have androgenic or antiandrogenic activity. The assay was carried out using immature castrated Sprague-Dawley male rats. After 7 days of the surgery, testosterone propionate (TP, 0.4 mg/kg/day) and test materials (low dose, 40 mg/kg/day; high dose, 400 mg/kg/day) were administered for 10 consecutive days by subcutaneous (s...

Variations in the skin of the prepuce are very rare. We report here a variation of the penile skin as observed in an adult male cadaver aged approximately 65 years. The penis was covered by thin nonhairy skin. The glans was not covered with prepuce. There was no evidence of circumcision. The ventral surface of the penis, adjacent to the glans, had a huge fold of skin. This fold resembled the prepuce and had a hole in it. The glans penis had a normal urethral meatus. There was no evidence of hypospadias as the entire ventral surface of the penis was covered completely by the skin...

REVIEW
Devang Sharma, Ryan P Smith
Placement of a penile prosthesis is an excellent option for well-selected patients, offering high patient satisfaction and a low rate of complications. Most urologists who perform the procedure are not high volume implanters and may have limited experience with troubleshooting intraoperative issues. In this review, the authors use current literature to provide recommendations for the management of various intraoperative issues such as difficultly with dilation, incongruent measurement, perforation, urethral injury, crossover, complications of reservoir placement, penile curvature, glans mobility, and hemostasis are all discussed...
