Abstract
Kissing nevus is a congenital melanocytic neoplasm arising in those parts of the body that split at some point during embryological development (i.e., eyelid; penis), resulting in two adjacent melanocytic nevi. To date, 23 cases of kissing nevus of the penis have been described, and dermatoscopic and histological findings are available in 4/23 cases. We report a dermatoscopic, histological and confocal microscopic analysis in a new case of the kissing nevus of the penis in a 57 years old man. Dermatoscopic analysis showed large globules in the central area and a peripheral pigment network; the histological examination confirmed the presence of an intradermal melanocytic nevus with minimal junctional component and congenital features. Moreover, we reported, for the first time, confocal microscopy findings in the kissing nevus of the penis, revealing the presence of dendritic cells in correspondence with the epidermis and suggesting a state of cellular activity. Considering the clinicopathological features of the lesion, a conservative approach was adopted, and a clinical follow-up was planned after six months.

Abstract
AIM: To examine neuroretinal function by using the multifocal electroretinography (mfERG) test in patients with neurofibromatosis type 1 (NF1) without optic pathway gliomas (OPGs).
METHODS: This study was conducted on 35 patients (35 eyes) with NF1 and 30 healthy subjects (30 eyes) for the control group. Each subject underwent a complete ophthalmological examination including spectral domain-optical coherence tomography (SD-OCT) and mfERG. The 1.5-Tesla magnetic resonance imaging (MRI) scan of the brain was performed in NF1 patients to assess the presence of OPGs. All participants were recruited having a best corrected visual acuity (BCVA) of no less than 20/20 in each eye. The amplitude and implicit time of the P1 wave (first-order Kernel component) were evaluated on mfERG. Data analysis was carried out in the two central degrees and in the four quadrants from two to 25 degrees of visual field.
RESULTS: Statistically significant results were obtained for the P1 wave amplitudes in the 4 quadrants in NF1 patients compared to healthy controls, while the reduction was not significant in the 2 central degrees between the groups. A statistically significant difference was observed among the P1 wave amplitudes as recorded in the 4 quadrants within the NF1 group, with lower amplitudes detected in the nasal quadrants. No differences in the implicit times were recorded in the 2 central degrees and in the 4 quadrants as compared between NF1 patients and controls.
CONCLUSION: Impaired neuroretinal function in NF1 patients is expressed in a decreased amplitude of the P1-wave between 2 and 25 central retinal degrees on mfERG. Altered intracellular signal transduction due to abnormal neurofibromin-mediated cyclic adenosine monophosphate (cAMP) generation, can be involved. The possible use of mfERG as subclinical retinal damage indicator has a potential utility in clinical practice for the follow-up of NF1 patients.

Abstract
OBJECTIVE To investigate the risk and pattern of tumors in italian neurofibromatosis type 1 (NF1) patients. MATERIALS AND METHODS A retrospective single institution case review of 711 patients (seen between March 1992 and February 2018) with NF1 was conducted to identify individuals with diagnoses of both NF1 and neoplasm. NF1-associated tumors have been collected and analyzed. RESULTS We identified 221 tumors in 191 subjects with a percentage of 26.9%, diagnosed at a median age of 32.5 years (range, 0.6-70.1 years); 111 of these patients were females (58%) and all were fol-lowed up for a median of 5.3 years. The cumulative risks for tumor in patients with NF1 by the ages of 30 and 60 years were 10% and 42.5%, respectively. In our patients with tumor, overall survival at 70 years was significantly shorter than in those without it (50% vs 95%, P<0.0001). We found an unequivocally increased incidence for breast cancer in females (33 cases observed). CONCLUSIONS Tumors that develop in patients with NF1 are heterogeneous, our data are consistent with other reports suggesting an increase in some cancers risk among these individuals, therefore systematic medical follow-up in people with NF1 is important.

Abstract
Background Basal cell carcinoma can simulate melanoma and specific dermoscopic criteria have not yet been defined in a large cohort. Objective To identify dermoscopic “trump” characteristics for differential diagnosis, identify cluster groups and assess the clinical impact of this study's findings. Methods Retrospective, multicentric comparative study of atypical, non‐facial basal cell carcinoma (≥1 seven‐point checklist criteria) and melanoma (with at least one BCC criteria) at dermoscopy. Observed dermoscopic features were used to develop a proposed score. Lesion clusters were defined with hierarchical analysis. Clinical impact was assessed with a blinded reader study following this study's results. Results A total of 146 basal cell carcinoma and 76 melanoma were included. Atypical vascular pattern was common to most lesions (74.5%). Twelve trump features were included in the proposed score (sensitivity 94.1% and specificity 79.5%). Cluster analysis identified 3 basal cell carcinoma and 3 melanoma clusters. Findings improved overall diagnostic accuracy and confidence (26.8% and 13.8%, respectively; p < 0.001). Conclusions These findings support the notion that atypical vascular pattern should be considered a shared feature of both melanoma and atypical basal cell carcinoma. Our proposed score improves diagnostic accuracy and confidence. Absence of pigmented features was associated with lower diagnostic accuracy and confidence.

Abstract
Introduction Gorlin-Goltz syndrome (GGS) also known as nevoid basal cell carcinoma syndrome (NBCCS) is a complex rare genetic disorder characterized by a wide range of clinical and radiological manifestations. Ophthalmological alterations have always been reported, but no study on the eventual pattern visual evoked potentials (pVEPs) abnormalities has yet been published. Purpose The purpose of the study was to evaluate the functionality of the optic pathways in a group of NBCCS patients through pattern reversal VEPs, after a thorough exclusion of subjects with preexisting ocular and optic pathways pathologies. Methods Nineteen NBCCS patients (31 eyes) and 20 healthy controls (40 eyes) have been recruited for this study. All subjects underwent an evaluation of the functionality of the optic pathways through pVEPs with small (120ʹ), medium (60ʹ), and large (15ʹ) check size stimulation. Results NBCCS patients showed a statistically significant alteration in the transmission of the macular pathway function when compared to controls. PVEPs analysis confirmed a reduced amplitude and an increased latency of the P100 component, suggesting an involvement of the visual pathway even in the absence of ocular clinical manifestations. Conclusion Visual pathways may have been affected both by a subclinical myelination deficit, determined directly by the genetic alteration, as well as by neurological abnormalities typical of this syndrome. Further studies are warranted.

Abstract
BACKGROUND Neurofibromatosis Type I (NF1), also termed von Recklinghausen disease, is a rare genetic disorder that is transmitted by autosomal dominant inheritance, with complete penetrance and variable expressivity. It is caused by mutation in the NF1 gene on chromosome 17 encoding for neurofibromin, a protein with oncosuppressive activity, and it is 50% sporadic or inherited. The disease is characterized by a broad spectrum of clinical manifestations, mainly involving the nervous system, the eye and skin, and a predisposition to develop multiple benign and malignant neoplasms. Ocular diagnostic hallmarks of NF1 include optic gliomas, iris Lisch nodules, orbital and eyelid neurofibromas, eyelid café-au-lait spots. Choroidal nodules and microvascular abnormalities have recently been identified as additional NF1-related ocular manifestations. The present study was designed to describe the features and clinical significance of a new sign related to the visual apparatus in NF-1, represented by hyperpigmented spots (HSs) of the fundus oculi. RESULTS HSs were detected in 60 (24.1%) out of 249 patients with NF1, with a positive predictive value of 100% and a negative predictive value of 44.2%. None of the healthy subjects (150 subjects) showed the presence of HSs. HSs were visible under indirect ophthalmoscopy, ultra-wide field (UWF) pseudocolor imaging and red-only laser image, near-infrared reflectance (NIR)-OCT, but they were not appreciable on UWF green reflectance. The location and features of pigmentary lesions matched with the already studied NF1-related choroidal nodules. No significant difference was found between the group of patients (n = 60) with ocular HSs and the group of patients (n = 189) without ocular pigmented spots in terms of age, gender or severity grading of the disease. A statistically significant association was demonstrated between the presence of HSs and neurofibromas (p = 0.047), and between the presence of HSs and NF1-related retinal microvascular abnormalities (p = 0.017). CONCLUSIONS We described a new ocular sign represented by HSs of the fundus in NF1. The presence of HSs was not a negative prognostic factor of the disease. Following multimodal imaging, we demonstrated that HSs and choroidal nodules were consistent with the same type of lesion, and simple indirect ophthalmoscopy allowed for screening of HSs in NF1.

Abstract
OBJECTIVE To better understand the real prevalence of cutaneous manifestations, in Neurofibromatosis type 1. MATERIALS AND METHODS We reviewed all clinical charts of 1102 NF1 patients followed by February 1983 to February 2020 at the "Sapienza" University of Rome, Italy. NF1 patients are seen usually every year by a dermatologist. RESULT Café-au-lait macules were shown in 1063 patients (96.5%), axillary and inguinal freckling in 991 (90%) and neurofibromas in 861 (78.1%). Other skin manifestations included: lipoma (6.2%), nevus anemicus (3.9%), psoriasis (3.4%), spilus nevus (3.2%), juvenile xanthogranuloma (3.2%), vitiligo (2.3%), Becker's nevus (1.9%), melanoma (0.7%) and poliosis (0.5%). CONCLUSION Neurofibromatosis type 1 is a multisystem disorder primarily involving the skin and nervous system. The clinical manifestations are extremely variable even within a family. This study was performed to delineate the prevalence of cutaneous manifestations in NF1.

Abstract
AIM OF THE STUDY To investigate, in vivo and in vitro, the fibroblast-to-myofibroblast transition in patients with hypermobile Ehlers-Danlos Syndrome (EDS). To analyze the dermis of patients with classical form of EDS (cEDS) and with hEDS, to identify qualitative and/or quantitative differences in ECM component and ultrastructural changes in collagen. MATERIALS AND METHODS Seven subjects, aged over 18, two with cEDS and five with hEDS underwent two skin biopsy. One sample was prepared for transmission electron microscopy (TEM), the other for immunofluorescence. The diameter of collagen fibers was measured with TEM. Fibrils were analyzed in four patients: the two with cEDS and two with hEDS. For each patient, the diameter of n=250 collagen fibrils was measured. αSMA was used as specific marker for myofibroblast to highlight their presence in vivo in the skin of patients with hEDS. RESULT IF observation could not assess an increased expression of αSMA in hEDS patients, which showed no statistical difference compared to classic form patients. The major result from the analysis of TEM images is the clear difference in ECM composition between the two forms of EDS: ECM in hEDS is optically more dense and more prominently composed of elastic fibers. CONCLUSION Our study provides the following important evidence: 1) the absence in vivo of dermal fibroblasts in patients with hEDS, demonstrated by αSMA negativity; 2) the presence of statistically significant changes in the diameter of collagen fibrils between the classic and the hypermobile forms.

BACKGROUND Basal cell carcinoma (BCC) is the most common skin cancer, and it can be easily treated by surgery or by various other physical modalities and topical chemotherapy. For metastatic, locally advanced BCC and for cancers that cannot be removed by surgery, systemic drugs known as hedgehog pathway blocker are used. High-frequency ultrasound (HFUS) is a non- invasive technique used in diagnosis of some skin cancers. It has proven potentially useful for BCC management. In this study we used high frequency ultrasounds to evaluate BCCs' thickness and the correlation with dermoscopic features. METHODS We examined 86 basal cell carcinomas with dermoscopy and with high-frequency ultrasound. The main patterns identified by ultrasound were linear, ellipsoid and non-specific or undefined. Patients were divided by sex and age. The BCCs were grouped by anatomic location. Finally, we recorded specific dermoscopic features of BCCs noting their presence/absence in lesions overall and in each of four quadrants. Then the lesions were excised, and histological examination was made with definition of tumor thickness (in mm). RESULTS In our study, two main echographic patterns were described: linear, associated with superficial BCC, and ellipsoid, found primarily in nodular variants. However, a small percentage of lesions have otherwise non-specific patterns. We observed a significant correlation between echographic tumor thickness and histotype. We observed high concordance between histological tumor thickness and ultrasounds. Also, dermoscopic criteria as large branching and blue ovoid nests were significantly associated with heightened histologic and echographic assessments of tumor thickness. CONCLUSIONS Our study confirmed the utility of ultrasound in the diagnosis of BCCs and for the first time we have correlated ultrasounds' patterns with dermoscopy and tumor thickness.

Abstract
PURPOSE The aim of this study is to evaluate ocular surface morphological and functional changes in patients with neurofibromatosis type 1 (NF1). METHODS Twenty-eight patients with NF1 and 14 healthy subjects were included in this study. All participants underwent a medical history collection, a complete ophthalmological examination including slit lamp exam and assessment of best-corrected visual acuity (BCVA), corneal sensitivity, and lacrimal function (Schirmer test and fluorescein tear break-up time test). Corneal nerves' morphology and endothelial cells density were evaluated by in vivo corneal confocal microscopy (IVCM). Tear and conjunctiva epithelium samples were collected to evaluate nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) tear levels and conjunctival expression of their receptors TrkA and p75NTR. RESULTS Patients with NF1 showed a significant decrease of FTBUT when compared with healthy subjects (p < 0.001). Corneal sensitivity was ≤ 50 mm in 46% of NF1 patients. IVCM showed a significant increase of corneal nerve branching and of corneal endothelial cells density. No significant difference was observed between the two groups on NGF and BDNF tear levels and conjunctival expression of their receptors. CONCLUSION This study demonstrated the presence of ocular surface changes in NF-1 patients including decrease of tear stability and of corneal sensitivity. Patients with NF1 also showed changes of corneal endothelial cells' density.

Abstract
Background Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is a rare genetic disorder that is transmitted in an autosomal dominant manner with complete penetrance and variable expressivity. It is caused in 85% of the cases with a known etiology by pathogenic variants in the PTCH1 gene, and is characterized by a wide range of developmental abnormalities and a predisposition to multiple neoplasms. The manifestations are multiple and systemic and consist of basal cell carcinomas in various regions, odontogenic keratocistic tumors and skeletal anomalies, to name the most frequent. Despite the scarce medical literature on the topic, ocular involvement in this syndrome is frequent and at the level of various ocular structures. Our study focuses on the visual apparatus and its annexes in subjects with this syndrome, in order to better understand how this syndrome affects the ocular system, and to evaluate with greater accuracy and precision the nature of these manifestations in this group of patients. Results Our study confirms the presence of the commonly cited ocular findings in the general literature regarding the syndrome [hypertelorism (45.5%), congenital cataract (18%), nystagmus (9%), colobomas (9%)] and highlights strabismus (63% of the patients), epiretinal membranes (36%) and myelinated optic nerve fiber layers (36%) as the most frequent ophthalmological findings in this group of patients. Conclusions The presence of characteristic and frequent ocular signs in the Gorlin- Goltz syndrome could help with the diagnostic process in subjects suspected of having the syndrome who do not yet have a diagnosis. The ophthalmologist has a role as part of a multidisciplinary team in managing these patients. The ophthalmological follow-up that these patients require, can allow, if necessary, a timely therapy that could improve the visual prognosis of such patients.

Abstract
BACKGROUND Estrogens play a key role in the skin. They are associated with an increased production of melanin, proliferation of melanocytes, increased skin thickness and increased cutaneous vascularization. Spitz and Reed nevi are acquired melanocytic lesions that generally develop during childhood or adolescence, a period of changes in sex hormones background. Our study project aimed at investigating, through immunohistochemical analysis, the expression levels of ERß receptors and their expression patterns (cytoplasmic or nuclear) in Spitz and Reed nevi. METHODS In our study, we collected a total of 86 melanocytic lesions of patients: of these, 16 were common nevi, 23 were Spitz nevi, 18 were Reed nevi and 29 were melanomas. Expression curves for estrogen receptors were constructed using the Kaplan-Meier method and compared using a log-rank test. Statistical analysis was performed using MedCalc® (MedCalc Software, Ostend, Belgium). Immunohistochemical analysis on all histological sections of nevi and melanomas was performed to evaluate the expression levels of of ERß and their expression patterns (cytoplasmic or nuclear). The agreement between the operators was calculated using Fleiss κ values. RESULTS The correlation between immunoreactivity for the β-estrogen receptor and the sex of patients with Spitz and Reed nevi showed that immunoreactivity was higher in male patients. The correlation between β-estrogen receptor immunoreactivity and patient age for Spitz and Reed nevi showed no statistically significant correlation. Correlation between immunoreactivity for the β-estrogen receptor and histotype: Spitz and Reed nevi showed a high intensity, while in common nevi and in melanomas the immunoreactive was low. The correlation between receptor immunoreactivity for β estrogens and Breslow thickness in melanomas indicated that Breslow thickness of non-immunoreactive melanomas for ERβ was much higher than those showing high immunoreactivity for this receptor. CONCLUSIONS Spitz and Reed nevi express a higher immunoreactivity for estrogens than common nevi and melanomas, especially those with a high Breslow thickness; and immunoreactivity is higher in younger age groups.

Abstract
PURPOSE The aim of this study was to provide a classification of the different retinal vascular arrangements in neurofibromatosis 1 (NF1), with appropriate qualitative and quantitative information. METHODS This study was conducted on 334 consecutive patients with NF1 and 106 sex-matched and age-matched healthy control subjects. Each patient underwent a comprehensive ophthalmological examination inclusive of near-infrared reflectance retinography by using the spectral domain Optical coherence tomography (OCT), a complete dermatological examination and 1.5 T MRI scan of the brain to assess the presence of optic nerve gliomas. To evaluate the predictability and the diagnostic accuracy of our identified retinal microvascular arrangements, we calculated the diagnostic indicators for each pattern of pathology, with corresponding 95% CI. In addition, we evaluated the association between the microvascular arrangements and each National Institutes of Health diagnostic criteria. RESULTS Microvascular abnormalities were detected in 105 of 334 NF1 patients (31.4%), the simple vascular tortuosity was recognised in 78 of 105 cases (74.3%) and whether the corkscrew pattern and the moyamoya-like type showed a frequency of 42.8% (45 of 105 cases) and 15.2% (16 of 105 cases), respectively. We found a statistically significant correlation between the presence of retinal microvascular abnormalities and the patient age (p=0.02) and between the simple vascular tortuosity, the patient age and the presence of neurofibromas (p=0.002 and p=0.05, respectively). CONCLUSIONS We identified microvascular alterations in 31.4% of patients and a statistically significant association with patient age. Moreover, the most frequent type of microvascular alterations, the simple vascular tortuosity, resulted positively associated with age and with the presence of neurofibromas.

Abstract
The fragile X mental retardation protein (FMRP) is lacking or mutated in patients with the fragile X syndrome (FXS), the most frequent form of inherited intellectual disability. FMRP affects metastasis formation in a mouse model for breast cancer. Here we show that FMRP is overexpressed in human melanoma with high Breslow thickness and high Clark level. Furthermore, meta-analysis of the TCGA melanoma data revealed that high levels of FMRP expression correlate significantly with metastatic tumor tissues, risk of relapsing and disease-free survival. Reduction of FMRP in metastatic melanoma cell lines impinges on cell migration, invasion and adhesion. Next-generation sequencing in human melanoma cells revealed that FMRP regulates a large number of mRNAs involved in relevant processes of melanoma progression. Our findings suggest an association between FMRP levels and the invasive phenotype in melanoma and might open new avenues towards the discovery of novel therapeutic targets.

Abstract
Insulin-like-factor-binding-protein 3 (IGFBP-3) is known to modulate the activity of insulin-like growth factors (IGFs) besides having a number of IGF-independent effects on cell growth and survival. IGFBP-3 has been reported to decrease significantly in the blood serum of patients affected by certain cancers. In the present work, we have evaluated the levels of IGFBP-3 in the blood serum and tissues of patients affected by cutaneous melanoma, showing that loss of IGFBP-3 from both is strongly correlated with disease progression and reduced survival. In vitro treatment with IGFBP-3 of human and murine metastatic melanoma cell lines specifically inhibited the cells' migratory and invasive behaviour, inducing up-regulation of melanocytic differentiation markers such as tyrosinase activity and melanin content. A molecular analysis of the cellular pathways transducing the effect of IGFBP-3 implicated the Akt-GSK3β axis. Moreover, administration of IGFBP-3 in vivo to SCID mice inoculated with human metastatic melanoma cells strongly reduced or completely inhibited tumor growth. In summary, IGFBP-3 appears to exert a specific inhibitory effect on melanoma growth and dissemination, suggesting that it may qualify as a useful therapeutic agent in melanomas and perhaps other cancers, at the least as a valid adjuvant therapy during treatment with conventional anti-tumoral drugs.

Abstract
BACKGROUND The last melanoma staging system of the 2009 American Joint Committee on Cancer takes into account, for stage IV disease, the serum levels of lactate dehydrogenase (LDH) and the site of distant metastases. OBJECTIVE Our aim was to compare the significance of metastatic volume, as evaluated at the time of stage IV melanoma diagnosis, with other clinical predictors of prognosis. METHODS We conducted a retrospective multicentric study. To establish which variables were statistically correlated both with death and survival time, contingency tables were evaluated. The overall survival curves were compared using the Kaplan-Meier method. RESULTS Metastatic volume and number of affected organs were statistically related to death. In detail, patients with a metastatic volume >15 cm(3) had a worse prognosis than those with a volume lower than this value (survival probability at 60 months: 6.8 vs. 40.9%, respectively). The Kaplan-Meier method confirmed that survival time was significantly related to the site(s) of metastases, to elevated LDH serum levels and to melanoma stage according to the latest system. CONCLUSION Our results suggest that metastatic volume may be considered as a useful prognostic factor for survival among melanoma patients.

Abstract
BACKGROUND Seborrheic keratosis (SK) is a frequent benign epithelial skin tumor. Generally its diagnosis is clinical, however SK can sometimes clinically simulate a melanocytic lesion; therefore we need dermoscopy to reach a correct diagnosis. Milia-like cysts and comedo-like openings are the common dermoscopic features of SK, but it is not a rare finding that SK can display one or more dermoscopic patterns suggestive of a melanocytic origin. OBJECTIVES We describe a case series of SKs with a blue globular pattern simulating a melanocytic lesion. METHODS We retrospectively evaluated 224 SKs seen during 2011 at the Dermatoscopy Unit of the Department of Dermatology, University of Rome 'Sapienza'. RESULTS Five SKs showed a blue globular pattern, without the SK main features generally seen in dermoscopy; globules were multiple, round or oval, well-demarcated, small and medium-sized, blue-colored and equally distributed within the lesion. Histopathologic examination was consistent with acanthotic SK. CONCLUSIONS Identification of the blue globular pattern can be helpful for the dermoscopic diagnosis of SK, especially when its common dermoscopic features are absent.

Abstract
We describe a 79-year-old female with a chronic venous ulceration infected by Staphylococcus aureus and Enterococcus faecalis and not responsive to conventional treatments. The patient was treated with Methyl-Aminolaevulinate Photodynamic Therapy (MAL-PDT). After four weeks the cutaneous swabs become negative and we observed a significant clinical improvement. Therefore we suppose that MALPDT could represent a valid therapeutic option in the treatment of infected chronic ulcers.

Abstract
BACKGROUND Different dermatoscopic algorithms have been developed to evaluate pigmented lesions of the skin, with pattern analysis being the most commonly used. We sought to develop and evaluate a diagnostic scoring system, the reticular point of view, to distinguish common melanocytic nevus from dysplastic nevus and from melanoma. METHODS We analyzed 1543 pigmented lesions, most of which contained a pigment network, and assessed the presence of linear extensions, thickened or hyperpigmented lines, areas of abrupt cut off, and areas with large "holes." We then conducted statistical analyses on these parameters to verify which of these exerted the most influence on the dermatologist's decision to surgically excise the lesion and to verify which feature was most linked to histopathologic signs of dysplasia or malignancy. RESULTS Among the lesions excised, histopathologic examination revealed 33 (10.28%) melanomas. Among these, 25 (75.75%) showed an asymmetric distribution of the pigment network, whereas 20 (60.6%) showed a linear extension of it. The analysis of our data showed that all the evaluated criteria were statistically significant and played an important role in the dermatologist's decision to perform surgical excision of the lesion. Regarding the diagnosis of melanoma, only the presence of large holes, areas of abrupt cut off, and linear extensions revealed statistical significance. LIMITATIONS Reticular point of view may be useful only in lesions with a large pigment network. It is not applicable in nodular, thick, and amelanotic melanomas that are usually lacking in pigment network. CONCLUSION Although pattern analysis represents the most effective analytical method in dermatoscopy, our scoring system may be useful to distinguish between benign lesions, which need only clinical follow-up, and malignant lesions, which need surgical excision.

Abstract
Bromhidrosis is a clinical disorder characterized by excessive or abnormal foul axillary odour due to the interaction of apocrine glands with micro-organisms which causes a serious personal and social handicap for affected people. We present the case of a 50-year-old caucasian female with bromhidrosis. The patient referred that this symptom had begun two months previously. Her past treatments included antibacterial soap, topical antibacterial agents and perfumes, but none of these relieved the patient of the odour. A cultural examination of axillary smear was carried out and it revealed the presence of ciprofloxacin sensible Sphingomonas paucimobilis. Therefore the patient was treated with ciprofloxacin and after 1 week the infection resolved completely.

Abstract
Phase variation through slippage-like mechanisms involving homopolymeric tracts depends in part on the absence of Dam-methylase in several pathogenic isolates of Neisseria meningitidis. In Dam-defective strains drg (dam-replacing gene), flanked by pseudo-transposable small repeated elements (SREs), replaced dam. We demonstrate that drg encodes a restriction endonuclease (NmeBII) that cleaves 5'-GmeATC-3'. drg is also present in 50% of Neisseria lactamica strains, but in most of them it is inactive because of the absence of an SRE-providing promoter. This is associated with the presence of GATmeC, suggesting an alternative restriction-modification system (RM) specific for 5'-GATC-3', similar to Sau3AI-RM of Staphylococcus aureus 3A, Lactococcus lactis KR2 and Listeria monocytogenes.

Abstract
The small GTPases Rab4, Rab5 and Rab7 are endosomal proteins which play important roles in the regulation of various stages of endosomal trafficking. Rab4 and Rab5 have both been localized to early endosomes and have been shown to control recycling and endosomal fusion, respectively. Rab7, a marker of the late endosomal compartment, is involved in the regulation of the late endocytic pathway. Here, we compare the role of Rab4, Rab5 and Rab7 in early and late endosomal trafficking in HeLa cells monitoring ligand uptake, recycling and degradation. Expression of the Rab4 dominant negative mutant (Rab4AS22N) leads to a significant reduction in both recycling and degradation while, as expected, Rab7 mutants exclusively affect epidermal growth factor (EGF) and low density lipoprotein degradation. As also expected, expression of the dominant negative Rab5 mutant perturbs internalization kinetics and affects both recycling and degradation. Expression of Rab4WT and dominant positive mutant (Rab4AQ67L) changes dramatically the morphology of the transferrin compartment leading to the formation of membrane tubules. These transferrin positive tubules display swellings (varicosities) some of which are positive for early endosomal antigen-1 and contain EGF. We propose that the Rab4GTPase is important for the function of the early sorting endosomal compartment, affecting trafficking along both recycling and degradative pathways.
