Review
There have been increasing reports of skin manifestations in COVID-19 patients. We conducted a systematic review and included manuscripts describing patients with positive RT-PCR coronavirus testing from nasopharyngeal swabs who also developed cutaneous manifestations. A total of 655 patients were selected, with different types of skin rashes: Erythematous maculopapular ( = 250), vascular ( = 146), vesicular ( = 99), urticarial ( = 98), erythema multiforme/generalized pustular figurate erythema/Stevens-Johnson syndrome ( = 22), ocular/periocular ( = 14), polymorphic pattern ( = 9), generalized pruritus ( = 8), Kawasaki disease ( = 5), atypical erythema nodosum ( = 3), and atypical Sweet syndrome ( = 1). Chilblain-like lesions were more frequent in the younger population and were linked to a milder disease course, while fixed livedo racemosa and retiform purpura appeared in older patients and seemed to predict a more severe prognosis. For vesicular rashes, PCR determined the presence of herpesviruses in the vesicle fluid, which raised the possibility of herpesvirus co-infections. The erythema-multiforme-like pattern, generalized pustular figurate erythema and Stevens-Johnson syndrome were most frequently linked to hydroxychloroquine intake. A positive PCR determination of SARS-COV-2 from conjunctival swabs suggest that eye discharge can also be contagious. These cutaneous manifestations may aid in identifying otherwise asymptomatic COVID-19 carriers in some cases or predict a more severe evolution in others.

UNLABELLED
Background and Objectives Over the last years, inflammatory bowel disease (IBD) has been reported on a high incidence in pediatric populations and has been associated with numerous extraintestinal manifestations, making its management a real challenge for the pediatric gastroenterologist. Dermatological manifestations in IBD are either specific, related to the disease activity or treatment-associated, or non-specific. This literature review aims to identify and report the dermatological manifestations of IBD in children, the correlation between their appearance and the demographical characteristics, the relationship between these lesions and disease activity, and to highlight the impact of dermatological manifestations on an IBD treatment regime.
MATERIALS AND METHODS
A systemic literature review was performed, investigating articles and case reports on dermatological manifestations in children with IBD starting from 2005. A total of 159 potentially suitable articles were identified and after the exclusion process, 75 articles were selected.
RESULTS
The most common dermatological manifestations reported in pediatric IBD are erythema nodosum and pyoderma gangrenosum. More rare cases of metastatic Crohn's disease, epidermolysis bullosa acquisita, small-vessel vasculitis, necrotizing vasculitis, leukocytoclastic vasculitis, cutaneous polyarteritis nodosa, and Sweet's syndrome have been reported. Oral manifestations of IBD are divided into specific (tag-like lesions, mucogingivitis, lip swelling with vertical fissures, aphthous stomatitis, and pyostomatitis vegetans) and non-specific. IBD treatment may present with side effects involving the skin and mucosa. Anti-tumor necrosis factor agents have been linked to opportunistic skin infections, psoriasiform lesions, and a potentially increased risk for skin cancer. Cutaneous manifestations such as acrodermatitis enteropathica, purpuric lesions, and angular cheilitis may appear secondary to malnutrition and/or malabsorption.
CONCLUSIONS
The correct diagnosis of dermatological manifestations in pediatric IBD is of paramount importance because of their impact on disease activity, treatment options, and a patient's psychological status.

Meta-Analysis
Studies have shown bidirectional relationships between short- or long-sleep duration and risk for obesity, non-communicable diseases, all-cause mortality and cardiovascular disease mortality. Increasing sleep duration may be an appropriate strategy to reduce cardiometabolic risk in short-sleeping individuals. The aim is to review the effects of sleep extension interventions on cardiometabolic risk in adults. The PubMed and Scopus databases were searched for relevant, English, peer-reviewed scientific publications (until August 2018). Seven studies that aimed to increase sleep duration in adults by any sleep extension intervention and described at least one cardiometabolic risk factor were included. These studies had a combined sample size of 138 participants who were either healthy (n = 14), healthy short-sleeping (n = 92), overweight short-sleeping (n = 10), or pre- or hypertensive short-sleeping (n = 22) individuals. The durations of the sleep extension interventions ranged from 3 days to 6 weeks, and all successfully increased total sleep time by between 21 and 177 min. Sleep extension was associated with improved direct and indirect measures of insulin sensitivity, decreased leptin and peptide tyrosine-tyrosine, and reductions in overall appetite, desire for sweet and salty foods, intake of daily free sugar, and percentage of daily caloric intake from protein. This review provides preliminary evidence for a role for sleep extension to improve cardiometabolic outcomes and directive towards future studies in the field of cardiometabolic health and sleep.

Review
Sweet's syndrome (SS) is an inflammatory disease characterized by fever, leucocytosis and distinctive skin lesions that histologically consist of a dermal infiltrate of neutrophils with nuclear fragmentation. Aseptic neutrophilic inflammation may occur also in other organs. Central nervous system involvement in SS, Neuro-Sweet's syndrome (NSS), is rare and reported especially among Asian patients. A systematic review of the literature has been performed to find articles reporting cases of SS with neurological involvement. The search terms: "Sweet's syndrome/disease with neurological involvement, Neuro Sweet Syndrome/Disease" were used in the Pubmed Database. Sixty-nine NSS patients including 46 males and 23 females, more Asian than Caucasian, have been described from 1983 to date. The average age was 48.7 year-old. The most representative neurologic symptom was the altered state of consciousness, followed by headache and memory disorders. Differently from SS with skin or other district involvement, NSS appears to be more common in Asian patients than in Caucasian ones and affects mainly the male sex in the third or fourth decade of life. A very wide range of symptoms and signs can occur, depending on which part of the nervous system is affected. Initial presentation is usually with the SS typical skin lesions followed by neurological involvement. However, also an opposite presentation or a simultaneous skin and nervous involvement may happen. Awareness of the possible neurological complications in SS is important to avoid unnecessary therapies for other forms of meningoencephalitis and lead to successful treatment with systemic corticosteroids.

Review
BACKGROUND
The keratocystic odontogenic tumours (KCOTs) account for between about 2% and 11% of all jaw cysts and can occur at any age. They are more common in males than females with a male:female ratio of approximately 2:1. Although they are benign, KCOTs are locally very aggressive and have a tendency to recur after treatment. Reported recurrence rates range from 3% to 60%. The traditional method for the treatment of most KCOTs is surgical enucleation. However, due to the lining of the cyst being delicate and the fact that they frequently recur, this method alone is not sufficient. Adjunctive surgical treatment has been proposed in addition to the surgical enucleation, such as removal of the peripheral bone (ostectomy) or resection of the cyst with surrounding bone (en-bloc) resection. Other adjunctive treatments proposed are: cryotherapy (freezing) with liquid nitrogen and the use of the fixative Carnoy's solution placed in the cyst cavity after enucleation; both of which attempt to address residual tissue to prevent recurrence.
OBJECTIVES
To assess the available evidence comparing the effectiveness of interventions for the treatment of KCOTs.
SEARCH METHODS
We searched the following electronic databases: the Cochrane Oral Health Group Trials Register (to 17 March 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2015, Issue 2), MEDLINE via Ovid (1946 to 17 March 2015) and EMBASE via Ovid (1980 to 17 March 2015). We searched the US National Institutes of Health Trials Register (http://clinicaltrials.gov) and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases.
SELECTION CRITERIA
Randomised controlled trials comparing one modality of intervention with another with or without adjunctive treatment for the treatment of KCOTs. Adults, over the age of 18 with a validated diagnosis of solitary KCOTs arising in the jaw bones of the maxilla or mandible. Patients with known Gorlin syndrome were to be excluded.
DATA COLLECTION AND ANALYSIS
Review authors screened trials for inclusion. Full papers were obtained for relevant and potentially relevant trials. If data had been extracted, it would have been synthesised using the fixed-effect model, if substantial clinical diversity were identified between studies we planned to use the random-effects model with studies grouped by action provided there were four or more studies included in the meta-analysis, and we would have explored the heterogeneity between the included studies.
MAIN RESULTS
No randomised controlled trials that met the inclusion criteria were identified.
AUTHORS' CONCLUSIONS
There are no published randomised controlled trials relevant to this review question, therefore no conclusions could be reached about the effectiveness or otherwise of the interventions considered in this review. There is a need for well designed and conducted randomised controlled trials to evaluate treatments for KCOTs.

Review
Initially lymphocytic Sweet's syndrome in male patients with myelodysplasia: a distinguished clinicopathological entity? Case report and systematic review of the literature.
BACKGROUND
Sweet's syndrome (SS) is an acute febrile neutrophilic dermatosis. It can occur as an idiopathic, drug-induced or malignancy-associated entity. SS is also seen in patients with myelodysplastic syndrome (MDS) where it may present atypically, both clinically and histologically. In a few rare cases of MDS, lymphocytic infiltrates are the presenting feature of SS.
METHODS
MEDLINE and Scopus were the data sources for our review.
RESULTS
A clinicopathological subsetemerged of 12 male SS patients with MDS and a mean age of 67.3 years in which the initial SS lesions were lymphocytic infiltrates. However, from 0.5 to 8 years later, sequential biopsies revealed neutrophilic dermal infiltration typical of SS.
CONCLUSION
Initially lymphocytic infiltrates in this subset could be attributed either to an early timing of the biopsy concerning the age of the lesion or to the dysgranulopoiesis syndrome. A possible relationship between the dysfunction of the receptor of the granulocyte-macrophage colony stimulating factor, the gene of which is located on the pseudoautosomal X-Y region, may exist in MDS patients with initially lymphocytic SS. This could explain the male gender of this subset and might establish initially lymphocytic SS as a distinguished clinicopathological entity for predicting the occurrence and even the prognosis of MDS.

Review
The aim of this study was to review all the paraneoplastic syndromes of primary tumours of the oral cavity. Metastatic tumours of the mouth and primary tumours of the oropharynx (including tonsils), and major salivary glands were excluded. The primary search was conducted on PubMed, Scopus and EMBASE, and included every paraneoplastic syndrome from a primary oral tumour described in English, French, or German papers during the last 20 years. The secondary search was conducted by handpicking articles from reviews on paraneoplastic syndromes of the head and neck. The aim of the tertiary search was to identify conditions that had been reported only rarely. We then cross-referenced "mouth neoplasm" with every paraneoplastic condition cited in relevant review articles. We classified the paraneoplastic syndromes that arose from tumours of the head and neck into six categories: endocrine, dermatological, vascular and haematological, rheumatoid, ocular, and neurological. The following conditions are described in this review: syndrome of inappropriate antidiuretic hormone production, hypercalcaemia, hypercalcaemia-leucocytosis syndrome, ectopic production of beta-human chorionic gonadotrophin, Bazex syndrome, Sweet syndrome, tripe palm syndrome, pemphigus, pityriasis rotunda, neutrophilic leukemoid reaction, cerebral venous sinus thrombophlebitis, digital ischaemia, dermatomyositis, necrotising myopathy, autoimmune retinal degeneration, and subacute cerebellar degeneration. Paraneoplastic syndromes of the oral cavity are a heterogeneous group. Most syndromes occur from squamous cell carcinoma and their aetiology is poorly understood. They are important to recognise as they can be the presenting complaint of a malignant tumour, change the prognosis, and considerably reduce the quality of life.
