Abstract
Congenital ichthyoses (CI) comprise a heterogeneous group of monogenic genetic skin diseases characterized by diffuse scaling, often associated with skin inflammation. Diagnosis of the individual form of ichthyosis is complex and is guided by clinical expertise. CI usually has a major impact on quality of life (QOL) and thus requires lifelong treatment. To date, there are no curative therapies, although various symptomatic treatment options exist. The present protocol for the management of CI has been drawn up in accordance with the recommendations published in 2012 by the French National Authority for Health, based on a literature review, with the help and validation of members of the French network for rare skin diseases (FIMARAD). It provides a summary of evidence and expert-based recommendations and is intended to help clinicians with the management of these rare and often complex diseases.

Abstract
Introduction: Ichthyosis is a group of disorders typically characterized by the accumulation of large scales over the skin. Mild bony deformities due to Vitamin D deficiency are commonly associated with this group of disorders which can be successfully treated with conventional Vitamin D supplementation. Severe multiple bony deformities requiring surgical correction are rarely reported and may be associated with various other disorders. Case Report: We report a case of a 15-year-old male with ichthyosis, short stature, and progressive multiple bony deformities since birth. The child was started on Vitamin D3 supplementation. Once biochemical parameters improved he underwent multiple corrective osteotomies in the bilateral tibia and right femur to improve gait mechanics. Our main concerns while managing the patient were regarding wound healing, secondary infection due to extensive scaling and healing at the osteotomy site. On follow-up we noted good healing at the osteotomy site without any surgical site infection or skin complications as well as improvement in gait mechanics and cosmesis. Conclusion: Severe bony deformities due to Vitamin D deficient are rare in ichthyosis and other syndromic causes should be ruled out. Surgical management can be beneficial in improving quality of life and gait biomechanics.

Abstract
BACKGROUND Short stature has been reported in congenital ichthyoses (CI), but few data exist on patients' nutritional status. OBJECTIVE To describe the nutritional status at the first evaluation of children and young adults with CI. METHODS Prospective observational study of patients assessed at a multidisciplinary clinic. Clinical variables and ichthyosis severity were collected. Anthropometric assessment was made by measuring weight and height, and nutritional status was classified based on the World Health Organization definitions for malnutrition. Analytical assessment included markers of nutritional status, fat-soluble vitamins, and micronutrients. RESULTS We included 50 patients with a median age of 5 years (IQR, 1.6-10.3). Undernutrition was found in 32% of patients, and 75% of the undernourished children presented growth impairment. Younger children and those with severe ichthyoses were the most affected. Micronutrient deficiencies were found in 60% of patients. Deficiencies of selenium (34%), iron (28%), vitamin D (22%), and zinc (4%) were the most frequent findings. LIMITATIONS Our small sample includes a heterogeneous group of ichthyoses. CONCLUSION Children with CI appear to be at risk of undernutrition, especially at younger ages. Nutritional deficiencies are common and should be monitored. Growth failure in children with ichthyosis could be caused by undernutrition and aggravated by nutritional deficiencies.

Abstract
Although first discovered in 1931, vitamin D has seen an increased interest in the scientific community over the past decades, including the dermatology field. Vitamin D promotes calcium and phosphorus absorption; however, the actions of vitamin D are not confined to bone. Indeed, there is now overwhelming and compelling scientific data that vitamin D plays a crucial role in a plethora of cellular function and in extra-skeletal health. Except for fatty fish livers, very few foods naturally contain vitamin D; and the major source of vitamin D comes from skin exposure to sunlight via ultraviolet B. Keratinocytes are unique in the body as not only do they provide the primary source of vitamin D for the body, but they also possess both the enzymatic machinery to metabolize the vitamin D produced to active metabolites. This has been referred to as the photoendocrine vitamin D system. Vitamin D regulates keratinocytes proliferation and differentiation; and plays a role in the defense against opportunistic infections. Multiple factors are linked to vitamin D status; and a growing number of dermatologic diseases has been linked to vitamin D status such as atopic dermatitis, psoriasis, vitiligo, and cutaneous cancers. In this article, we reviewed the potential determinants of vitamin D status, as its implications in dermatologic diseases.

Abstract
Fine particulate matter is a well-known air pollutant threatening public health. Studies have confirmed long-term exposure to the particles could decrease the pulmonary function, induce asthma exacerbation, and chronic obstructive pulmonary disease, as well as increase the incidence and mortality of lung cancer. A clinical study has explored that the prevalence and risks of vitamin D (VD) deficiency in various chronic disease and toxins induced tissue damage. Our current study aimed to explore the mechanism and further therapeutic potential of VD administration to ameliorate fine particles exposure induced pulmonary damage in vivo and in vitro. To elucidate the effects and mechanisms of VD in particles-induced pulmonary damage, a murine model was established with fine particles intratracheal instillation along with VD intramuscular injection. Our study demonstrated that treatment with VD attenuated particles-induced pulmonary damage and promoted tissue repair by repressing of TGFβ1 signaling pathway and upregulation of MMP9 expression. VD treatment could also regulate the autophagy-related signals along with activation of Nrf2 transcription factor. Furthermore, the results from the in vitro study demonstrated that VD protected against particles-induced cells' damage through the induction of autophagy in an Nrf2-dependent manner. VD treatment caused the degradation of P62 and its bound Keap1, which decreased the Nrf2 ubiquitination and increasing its protein stability. Our work explored a novel potential mechanism in the protection of VD in particles-induced pulmonary injury and tissue repair, and could further bring insights into exploring antifine particles exposure caused inflammation among other natural products and contributes to inflammation disease medical therapies.

Abstract
The vitamin D receptor (VDR) is found in nearly all, if not all, cells in the body. The enzyme that produces the active metabolite of vitamin D and ligand for VDR, namely CYP27B1, likewise is widely expressed in many cells of the body. These observations indicate that the role of vitamin D is not limited to regulation of bone and mineral homeostasis, as important as that is. Rather, the study of its extraskeletal actions has become the major driving force behind the significant increase in research articles on vitamin D published over the past several decades. A great deal of information has accumulated from cell culture studies, in vivo animal studies, and clinical association studies that confirms that extraskeletal effects of vitamin D are truly widespread and substantial. However, randomized, placebo-controlled clinical trials, when done, have by and large not produced the benefits anticipated by the in vitro cell culture and in vivo animal studies. In this review, I will examine the role of vitamin D signaling in a number of extraskeletal tissues and assess the success of translating these findings into treatments of human diseases affecting those extracellular tissues.

Abstract
PIBIDS syndrome (photosensitivity, ichthyosis, brittle hair, intellectual impairment, decreased fertility and short stature) is a variant of trichothiodystrophy. It is a rare form of autosomal recessive congenital ichthyosis. Short stature is a vital component of PIBIDS syndrome. We present the cases of two siblings in whom we diagnosed PIBIDS syndrome. On evaluation for short stature, they were found to have severe vitamin D deficiency, which on correction led to the patients having considerable gain in stature. With this case, we would also like to propose that vitamin D deficiency could be one of the treatable causes of short stature in PIBIDS syndrome.

Abstract
BACKGROUND To date, few studies have investigated serum vitamin D status in patients with inherited ichthyosis. The aim of this study was to determine the prevalence of vitamin D deficiency (defined as serum level <10 ng/mL) in a French cohort of patients and to identify associated risk factors. METHODS This was a prospective observational study performed in a hospital reference center with expertise for rare skin diseases. Patients' clinical characteristics were recorded. Serum concentration of 25-hydroxyvitamin D and parathyroid hormone were determined. For patients with vitamin D deficiency, serum calcium, serum phosphorus and bone mineral density were also investigated. Comparisons between groups (25-hydroxyvitamin D <10 ng/mL versus ≥10 ng/mL) were conducted by univariate and multivariate logistic regression. RESULTS Of the 53 included patients, 47 (88.7%) had serum 25-hydroxyvitamin D below the optimal level of 30 ng/mL: 18 (34%) had vitamin D sufficiency, 14 (26.4%) had vitamin D insufficiency, and 15 (28.3%) had vitamin D deficiency. A negative linear correlation was found between 25-hydroxyvitamin D and parathyroid hormone levels for the whole study population. Serum calcium and phosphorus levels were normal for the 15 patients with vitamin D deficiency. Bone mineral density was investigated for 11 of these latter 15 patients, and six of them had osteopenia. Winter/spring seasons of vitamin D measurement, severity of ichthyosis, and phototypes IV-VI were identified as independent risk factors for vitamin D deficiency. CONCLUSIONS Clinicians should be aware of the risk of vitamin D deficiency in the management of patients with inherited ichthyosis, especially in winter and spring, and in case of dark skin or severe disease.

Abstract
Harlequin ichthyosis (HI) is a rare and severe form of congenital ichthyosis. Linked to deletion and truncation mutations of a keratinocyte lipid transporter, HI is characterized by diffuse epidermal hyperkeratinization and defective desquamation. At birth, the HI phenotype is striking with thick hyperkeratotic plate-like scales with deep dermal fissures, severe ectropion and eclabium, among other findings. Over the first months of life, the hyperkeratotic covering is shed, revealing a diffusely erythematous, scaly epidermis, which persists for the remainder of the patient's life. Although HI infants have historically succumbed in the perinatal period related to their profound epidermal compromise, the prognosis of HI infants has vastly improved over the past 20 years. Here, we report a case of HI treated with acitretin, focusing on the multi-faceted management of the disease in the inpatient setting. A review of the literature of the management of HI during the perinatal period is also presented.
