Abstract
Terra firma-forme dermatosis (TFFD) is an acquired pigmentation disorder that promptly regresses after applying isopropyl alcohol 70%. The clinical presentation ranges from patches of brownish discoloration to velvety hyperkeratotic plaques. Critical analyses of current data are lacking, so etiologies, pathogenesis, and disease associations are still debated in the literature. A literature search was done in the PubMed and Google Scholar databases to identify the published papers reporting clinical cases of TFFD. Of 102 papers screened, 64 met the including criteria. Overall, the records of 256 patients presenting a mean age of 18.34 years and a female:male ratio of 1:37 were reviewed. The present article aims to provide a key point-summary regarding the clinical outcome, associated comorbidities, pathogenesis, histopathology, dermoscopy, and therapeutic modalities of TFFD.

Abstract
Terra firma-forme dermatosis is an underreported acquired pigmentation disorder caused by keratinocyte retention that is not mentioned in many textbooks. It is characterized by the onset of asymptomatic hyperpigmented patches or velvety plaques potentially involving any part of the body, including the trunk, extremities, and the skin folds such as neck, axilla, inguinal region, and umbilical folds. It affects both sexes equally and all age groups, although it seems more prevalent in children with a mean age of 10.4 years. The prompt regression after rubbing with an alcohol-soaked gauze is diagnostic and curative. The cause of this affection remains unknown, although less rigorous hygiene or an atopic background is contributory.

Abstract
Retronychia describes the proximal ingrowing of the nail plate. In the early stage, topical steroids are the gold standard therapy, while in the late stage surgical treatment is mandatory. We identified an intermediate severity stage of retronychia, where the topical treatment alone is ineffective and surgery is avoidable. Intralesional steroids turn the best treatment in these patients. A pilot study consisting of a 3-month treatment period and 9-month follow-up time was designed to evaluate the treatment outcome to intralesional steroid injections in patients affected by the intermediate-stage of toenail retronychia. The complete recovery of retronychia-associated nail abnormalities was observed in 27/28 recruited patients at the end of the treatment phase. Paronychia, nail plate discoloration, proximal nail fold (PNF) elevation, and discharge were reduced (P < .01) after one steroid administration, while nail regrowth became significant after two sessions. No significant difference in terms of clinical outcome was found, while pain VAS score and intra-operative pain evaluated with Wong-Baker faces scale were higher in the female group (P < .01). Limitation Lack of control group of patients. Despite its temporary effect, the intralesional triamcinolone injection is an effective, cheap, and safe treatment especially for the intermediate stage of retronychia.

Abstract
Background The hair whorl denotes the spiral disposition of hairs around an axis, which is determined by the follicle growing direction. Atypical variants of scalp hair patterns, identified by abnormally placed or multiple whorls, have been associated with early brain developmental disorders and several dysmorphic syndromes. Materials and Methods A 6-month case-control, prospective monocentric study included an overall number of 557 children. A logistic regression analysis was performed to evaluate the relationship between localization, the number of scalp hair whorls, and their association with neurofibromatosis type 1 (NF1). Results NF1 positively correlates with a frontal localization, whereas a negative association was found with a parietal whorl pattern (P < 0.001). Conclusion Evaluation of scalp whorls gains importance in the neonatal settings and may contribute to suspect the early diagnosis of NF1, as the related National Institutes of Health diagnostic criteria cannot be usually observed at an early age.

Abstract
BACKGROUND Nail tumors often pose a significant challenge for the clinician, as they are burdened by a high delay in diagnosis and paucity of clinical signs in the early stage. In most cases, the onset of pain or nail plate dystrophy leads to imaging investigations such as plain radiography, magnetic resonance imaging, and ultrasonography (US) when surgery is pending. MATERIAL AND METHODS A 2-year monocentric study evaluated the histologically confirmed cases of subungual glomus tumor (GT) and squamous cell carcinoma (SCC) with a pre-surgical US assessment, and reviewed their sonography features. A total of 7 digital GTs and 6 SCCs of the nail were collected. RESULTS GT and SCC are easily distinguishable on US. Compared to SCC, GT was positively associated with an ovoid shape, well-defined borders, bone cup-scalloping without cortical erosion, and a rich intralesional vascular pattern (P < 0.05). Vice versa, SCC was significantly correlated with irregular shape, ill-circumscribed margins, an infiltrative growth pattern with peripheral hypoechoic foci, posterior acoustic shadow, cortical erosion, and a highly vascular multipolar peripheral pattern (P < 0.05). CONCLUSION The rapid assessment of GT and SCC sonographic features may contribute to reduce diagnostic delay, expedite management, and decrease the risk of surgical relapse.

Abstract
BACKGROUND Pigmented purpuric dermatoses (PPDs) are a group of chronic-relapsing, inflammatory purpuras without vasculitis that typically involve the lower limbs. Five major types could be distinguished, according to the clinical and histopathologic analysis. The etiopathogenesis is still unknown and multiple factors have been considered. Prognosis seems not to be influenced by the different clinical forms of PPDs; nevertheless, no previous studies have investigated whether it could be influenced by the anatomical distribution of the disease. METHODS We enrolled 70 consecutive patients, including both adults and children with a clinical and histopathological diagnosis of PPD, to investigate possible correlations between the different types of PPDs, their anatomical distribution and prognosis. RESULTS We observed that patients, both adults and children, with an uncommon localization of the dermatoses, in particular with a diffuse localization (more than one body area affected), presented more frequently a persistent form of PPDs. CONCLUSIONS This is the first study that attempts to relate the anatomical extension of PPDs and their evolution over time. According to our analysis, it seems to be a statistical significance for the prognosis only for patients with Schamberg disease and involvement of lower limbs. However, studies on a larger population are needed.

Abstract
In this article, we report the sonographic features of vaccination granulomas in three children sensitized to aluminum. Although the recognition of the vaccination granuloma relies on the clinical examination, misdiagnosis is frequent, leading to distressful procedures or prolonged antibiotic administration. In all our cases, sonography revealed a teardrop-shaped echogenic central structure, suggesting the deposition of aluminum crystals along the route of administration with consequent subcutaneous degenerative changes, and a surrounding hypoechoic cap, which reflects the changeable inflammatory reaction and the granuloma formation.

Abstract
Background Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent skin disease of the pilosebaceous unit characterized by protean manifestations. Several studies have found an increased incidence and earlier presentation of this disease in patients carrying trisomy 21. Patients with Down syndrome (DS) have a higher risk of developing a wide range of cutaneous manifestations, including HS and chronic folliculitis. Recently, disseminate recurrent folliculitis (DRF) has been reported as an atypical monosymptomatic feature of HS at its onset. Objective To assess the prevalence of HS and DRF by comparing a cohort of patients carrying trisomy 21 vs pediatric controls. Methods A retrospective 2-year monocentric clinical study was performed by collecting clinical data of 131 patients with DS, aged 4-36 years, followed at the Dermatology Unit and Down Syndrome Regional Center of Bologna University. Data were matched with those coming from 12,351 pediatric controls. Results In DS patients, DRF and HS showed a prevalence of, respectively, 6.8% and 24.4%, while 5.3% of patients presented both diseases. In the control group the prevalence for HS+ and DRF+ was 0.5% and 1.2%, respectively, with a 0.14% of overlap cases. The association between HS and DRF proved to be statistically significant in both groups (P < 0.05). In the DS cohort the mean age of symptoms onset was 15.67 (SD: 2.29) years for HS and 13.11 (SD: 4.93) years for DRF. Buttocks were the most frequently affected body area for DRF followed by the inguinocrural area, while in HS buttocks were less frequently involved than groins and upper thighs. Conclusions Because of the later onset of HS, patients with DRF at an early age should be monitored for the possible onset of HS in the apocrine-bearing areas.

Abstract
We report here our experience on the use of dermoscopy for the detection of subungual red comets, which are sometimes present in the nails of patients affected by tuberous sclerosis complex. Dermoscopy allowed us to visualize, with better resolution than the naked eye, very tortuous capillaries surrounded by a whitish halo and close parallel binary tortuous capillaries. In some cases, subungual red comets are associated with the presence of periungual or subungual fibromas, but their exact pathogenesis remains unknown.

Abstract
Background Mucous membrane pemphigoid (MMP) is a heterogeneous group of blistering disorders affecting the mucosae with or without skin involvement, characterized by the presence of autoantibodies to components of the basement membrane zone, including the bullous pemphigoid antigen BP180 and β4 integrin. Current literature has shown that a minority of patients present circulating antibodies to laminin-332 and this population seems to be associated with a relatively high risk of malignancy. Objective To present our personal case series of patients with MMP-associated malignancy from a dermatology university hospital. Methods Twenty-two patients affected by MMP were seen in the period between 2001 and 2016; in 4 patients (18%) an associated cancer was detected. Results These patients were 2 men and 2 women, with a mean age of 69.7 years (range, 48-83). The associated malignancies included a breast cancer, a pancreatic adenocarcinoma, a metastatic laryngeal carcinoma, and a hepatic carcinoma. All patients had negative results for both BP180 and laminin-332 autoantibodies. Conclusion We confirm that MMP patients have a relatively high possibility of developing a solid cancer, but the autoantibody detection is not mandatory and is probably correlated with the severity of the disease.

Abstract
We report a case of long-standing inexplicable perianal ulcers. After exclusion of an inflammatory, infectious or neoplastic origin, a thorough personal history revealed that for many years the patient had been using analgesic suppositories containing indomethacin, caffeine, and prochlorperazine dimaleate, four to five times a week, for migraine. On stopping the suppositories, there was complete healing within 12 weeks. We hypothesize that vasoconstriction and vascular damage were the pathogenetic mechanisms behind the perianal ulcers.

Abstract
BACKGROUND Maintenance anti-tumour necrosis factor-α (anti-TNFα) treatment for Crohn's disease is the standard of care for patients with an inadequate response to corticosteroids and immunomodulators. AIM To compare the efficacy and safety of infliximab and adalimumab in clinical practice and assess the value of concomitant immunomodulator therapy. METHODS We performed an observational cohort study in consecutive patients with Crohn's disease qualifying for anti-TNFα treatment in Australia and New Zealand between 2007 and 2011. Demographic and clinical data were prospectively recorded to identify independent factors associated with induction and maintenance of response to infliximab or adalimumab, or to either anti-TNFα therapy. RESULTS Three hundred and twenty-seven patients (183 infliximab, 144 adalimumab) successfully applied for treatment. Eighty-nine percent responded in all groups and median maintenance of response was similar for the two agents. Concomitant immunomodulator with infliximab, but not adalimumab, demonstrated a significantly longer response overall (P = 0.002), and significantly fewer disease and treatment-related complications (P = 0.017). Corticosteroids at baseline, and/or in the preceding 12 months, were associated with a 9-13 times greater risk of disease flare during maintenance treatment as compared to no corticosteroids (P < 0.0001). Maintenance of response was similar in the anti-TNF naïve and anti-TNF experienced subgroups. CONCLUSIONS In this large, real-life study, we demonstrate infliximab and adalimumab to have similar response characteristics. However, infliximab requires concomitant immunomodulator to achieve optimal maintenance of response comparable to adalimumab monotherapy. The results of this study will assist clinicians in further optimising patient care in their day-to-day clinical practice.

Abstract
BACKGROUND The efficacy of infliximab has been demonstrated in patients with both acute severe and moderate-severe ulcerative colitis (UC). However, there is a need for 'real-life data' to ensure that conclusions from trial settings are applicable in usual care. We therefore examined the national experience of anti-tumour necrosis factor-α (TNF-α) therapy in UC. METHODS Case notes review of patients with UC who had received compassionate access (CA) anti-TNF-α therapy from prospectively maintained inflammatory bowel disease databases of six Australian adult teaching hospitals. RESULTS Patients either received drug for acute severe UC (ASUC) failing steroids (n = 29) or for medically refractory UC (MRUC) (n = 35). In ASUC, the treating physicians judged that anti-TNF-α therapy was successful in 20/29 patients (69%); in these cases, anti-TNF-α was able to be discontinued (after 1-3 infusions in 19/20 responders) as clinical remission was achieved. Consistent with this perceived benefit, only 7/29 (24%) subsequently underwent colectomy during a median follow up of 12 months (interquartile range (IQR) 5-16). Eight of the 35 patients with MRUC (23%) required colectomy during a median follow up of 28 months (IQR 11-43). The majority of these patients (20/35 or 57%) had anti-TNF-α therapy for ≥4 months, whereas, 27/29 (93%) of ASUC patients had CA for ≤3 months. CONCLUSIONS These data show an excellent overall benefit for anti-TNF-α therapy in both ASUC and MRUC. In particular, only short-duration anti-TNF-α was required in ASUC. These real-life data thus support the clinical trial data and should lead to broader use of this therapy in UC.

Abstract
TERT promoter (TERTp) mutation is the most common mutation in glioblastomas. It creates a putative binding site for Ets/TCF transcription factors, enhancing telomerase expression and activity, whereas the rs2853669 variant disrupts another Ets/TCF binding. We explore here the interaction between these two alterations, tumor genomic profile and the impact on prognosis. The TERTp and rs2853669 statuses were determined and confronted with the outcome and molecular profile, i.e., loss of chromosome 10q, CDKN2A deletion, IDH mutation, EGFR amplification, MGMT promoter methylation. 651 glioblastomas were selected (sex ratio = 1.35, median age 60.4 years, median survival 13.5 months). The TERTp mutation found in 481 patients (74 %) was independent from rs2853669 genotypes. TERTp mutation, but not rs2853669 status, was associated with older age (61.4 vs. 52.8 years). rs2853669 status had no impact on overall survival (OS) either in mutated TERTp or wild-type TERTp. Neither rs2736100 (TERT, 5q15.33) nor rs192011116 (TERC, 3q26.2) status had any impact on survival or showed any association with a TERTp mutation. The TERTp mutation was associated with EGFR amplification chromosome 10q loss, CDKN2A deletion and IDH wt. EGFR amplification was associated with a better outcome in TERTp mutated GBM, and a worse outcome in TERTp WT. This study-the largest analyzing the TERTp mutation and the rs2853669 polymorphism-fails to find any prognostic impact of rs2853669. It confirms the dual prognostic impact of EGFR amplification depending on TERTp status.

Abstract
BACKGROUND There are few centres which specialise in the care of adults with inborn errors of metabolism (IEM). To anticipate facilities and staffing needed at these centres, it is of interest to know the distribution of the different disorders. METHODS A survey was distributed through the list-serve of the SSIEM Adult Metabolic Physicians group asking clinicians for number of patients with confirmed diagnoses, types of diagnoses and age at diagnosis. RESULTS Twenty-four adult centres responded to our survey with information on 6,692 patients. Of those 6,692 patients, 510 were excluded for diagnoses not within the IEM spectrum (e.g. bone dysplasias, hemochromatosis) or for age less than 16 years, leaving 6,182 patients for final analysis. The most common diseases followed by the adult centres were phenylketonuria (20.6%), mitochondrial disorders (14%) and lysosomal storage disorders (Fabry disease (8.8%), Gaucher disease (4.2%)). Amongst the disorders that can present with acute metabolic decompensation, the urea cycle disorders, specifically ornithine transcarbamylase deficiency, were most common (2.2%), followed by glycogen storage disease type I (1.5%) and maple syrup urine disease (1.1%). Patients were frequently diagnosed as adults, particularly those with mitochondrial disease and lysosomal storage disorders. CONCLUSIONS A wide spectrum of IEM are followed at adult centres. Specific knowledge of these disorders is needed to provide optimal care including up-to-date knowledge of treatments and ability to manage acute decompensation.

Abstract
Intracellular accumulations of altered, misfolded proteins in neuronal and other cells are pathological hallmarks shared by many neurodegenerative diseases including amyotrophic lateral sclerosis (ALS). Mutations in several genes give rise to familial forms of ALS. Mutations in Sigma receptor 1 have been found to cause a juvenile form of ALS and frontotemporal lobar degeneration (FTLD). We recently described altered localization, abnormal modification and loss of function of SigR1 in sporadic ALS. In order to further elucidate the molecular mechanisms underlying SigR1-mediated alterations in sporadic and familial ALS, we extended our previous studies using neuronal SigR1 knockdown cell lines. We found that loss of SigR1 leads to abnormal ER morphology, mitochondrial abnormalities and impaired autophagic degradation. Consistent with these results, we found that endosomal trafficking of EGFR is impaired upon SigR1 knockdown. Furthermore, in SigR1-deficient cells the transport of vesicular stomatitis virus glycoprotein is inhibited, leading to the accumulation of this cargo protein in the Golgi apparatus. Moreover, depletion of SigR1 destabilized lipid rafts and associated calcium mobilization, confirming the crucial role of SigR1 in lipid raft and intracellular calcium homeostasis. Taken together, our results support the notion that loss of SigR1 function contributes to ALS pathology by causing abnormal ER morphology, lipid raft destabilization and defective endolysosomal pathways.

Abstract
Epidemiological surveys were performed in Northern Sardinia (Italy) in a 10-year-old vineyard affected by "Bois noir" disease. Samples collected between May and October 2003 from chlorotic and stunted weeds belonging to 14 different taxonomic groups were indexed molecularly for detection of phytoplasmas. Nested polymerase chain reaction (PCR) assays using primers specific for the phytoplasma 16SrDNA gene showed three of six Calendula arvensis, one of two Solanum nigrum, and one of seven Chenopodium spp. assayed positive. Restriction fragment length polymorphism analyses and sequencing of amplified 16SrDNA fragments identified a putative phytoplasma in the ribosomal subgroup 16SrII-E. Further characterization of the rps3 gene, coding a ribosomal protein, confirmed the identification. However, the weeds and leafhop-per species collected in the vineyard tested negative by PCR assays for the Stolbur phytoplasma, the causal agent of "Bois noir". This is the first report of a phytoplasma of the 16SrII-E subgroup infecting C. arvensis, S. nigrum, and Chenopodium spp.
