Basal cell carcinoma-a clinical indicator of immunosuppression.

Background: Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are skin-derived carcinomas. The literature strongly connects SCC with acquired immunosuppression. Current data regarding BCC's association with immunosuppressive comorbidities are vague. The primary objective of this study was to establish the correlations between BCC and immunosuppressive comorbidities of patients. Materials and methods: We conducted a retrospective cohort study on 275 patients with a histopathological proven diagnosis of BCC from October 2019 to October 2023. Demographic data, BCC characteristics, and patients' comorbidities were analyzed. Comorbidities were classified as non-immunosuppressant and immunosuppressant (primary and secondary immunodeficiencies). Results: We recorded 292 BCCs from 275 patients (142 females, 133 males), with equally distributed skin phototypes. 66.44% of the BCCs were detected in patients with various comorbidities (p < 0.001), of which 81.44% had immunosuppressive comorbidities (p < 0.001). All the immunosuppressive comorbidities were secondary and included diabetes mellitus (47.55%), history of solid or hematogenous cancer in the last 5 years (26.57%), chronic kidney disease (8.39%), chronic infections (9.09%), and antirheumatic immunosuppressive therapies (8.39%) (p < 0.001). BCC patients with immunosuppressive comorbidities did not develop larger BCCs (p = 0.2577) or more aggressive subtypes (p = 0.4269) and BCC did not arise earlier in their life (p < 0.001). BCC on the nasal pyramid was frequent in cancer history patients (p = 0.008). The ulcerated form of BCC is more confined to patients with chronic kidney disease (p = 0.006). Multiple BCCs are more frequent in patients with secondary immunodeficiencies (p = 0.027). Conclusion: BCC represents a clinical indicator of secondary immunodeficiency. Further research should establish if cancer screening campaigns may be beneficial in BCC patients.

The Impact of Patient Characteristics, Risk Factors, and Surgical Intervention on Survival in a Cohort of Patients Undergoing Neoadjuvant Treatment for Cervical Cancer.

Introduction: Cervical cancer is among the most frequent types of neoplasia worldwide and remains the fourth leading cause of cancer death in women, a fact that raises the necessity for further development of therapeutic strategies. NCCN guidelines recommend radiation therapy with or without chemotherapy as the gold standard for locally advanced cervical cancer. Also, some studies claim that performing surgery after chemo-radiation therapy does not necessarily improve the therapeutic outcome. This study aims to determine the impact of the risk factors, various characteristics, and surgical treatment for patients in different stages of the disease on survival rate. Material and methods: Our study started as a retrospective, observational, unicentric one, carried out on a cohort of 96 patients diagnosed with cervical cancer from the surgical department of the Bucharest Oncological Institute, followed from 1 January 2019 for a period of 3 years. After the registration of the initial parameters, however, the study became prospective, as the patients were closely monitored through periodical check-ups. The end-point of the study is either the death of the participants or reaching the end of the follow-up period, and, therefore, we divided the cohort into two subgroups: the ones who survived after three years and the ones who did not. All 96 patients, with disease stages ranging from IA2 to IIIB, underwent radio-chemotherapy followed by adjuvant surgery. Results: Among the 96 patients, 45 (46%) presented residual tumor after radio-chemotherapy. Five patients (5%) presented positive resection margins at the post-operative histopathological examination. The presence of residual tumor, the FIGO stage post-radiotherapy, positive resection margins, and lympho-vascular and stromal invasions differed significantly between the subgroups, being more represented in the subgroup that reached the end-point. Variables correlated with the worst survival in Kaplan-Meier were the pelvic lymph node involvement-50% at three years (p-0.015)-and the positive resection margins-only 20% at three years (p < 0.001). The univariate Cox model identified as mortality-associated risk factors the same parameters as above, but also the intraoperative stage III FIGO (p < 0.001; HR 9.412; CI: 2.713 to 32.648) and the presence of post-radiotherapy adenopathy (p-0.031; HR: 3.915; CI: 1.136 to 13.487) identified through imagistic methods. The independent predictors of the overall survival rate identified were the positive resection margins (p-0.002; HR: 6.646; CI 2.0 to 22.084) and the post-radiotherapy stage III FIGO (p-0.003; HR: 13.886; CI: 2.456 to 78.506). Conclusions: The most important predictor factors of survival rate are the positive resection margins and the FIGO stage after radiotherapy. According to the NCCN guidelines in stages considered advanced (beyond stages IB3, IIA2), the standard treatment is neoadjuvant chemoradiotherapy. In our study, with radical surgery after neoadjuvant therapy, 46% of patients presented residual tumor at the intraoperative histopathological examination, a fact that makes the surgical intervention an important step in completing the treatment of these patients. In addition, based on the patient's features/comorbidities and the clinical response to chemotherapy/radiotherapy, surgeons could carefully tailor the extent of radical surgery, thus resulting in a personalized surgical approach for each patient. However, a potential limitation can be represented by the relatively small number of patients (96) and the unicentric nature of our study.

Is Spontaneous Preterm Prelabor of Membrane Rupture Irreversible? A Review of Potentially Curative Approaches.

There is still no curative treatment for the spontaneous preterm prelabor rupture of membranes (sPPROM), the main cause of premature birth. Here, we summarize the most recent methods and materials used for sealing membranes after sPPROM. A literature search was conducted between 2013 and 2023 on reported newborns after membranes were sealed or on animal or tissue culture models. Fourteen studies describing the outcomes after using an amniopatch, an immunologic sealant, or a mechanical cervical adapter were included. According to these studies, an increase in the volume of amniotic fluid and the lack of chorioamnionitis demonstrate a favorable neonatal outcome, with a lower incidence of respiratory distress syndrome and early neonatal sepsis, even if sealing is not complete and stable. In vivo and in vitro models demonstrated that amniotic stem cells, in combination with amniocytes, can spontaneously repair small defects; because of the heterogenicity of the data, it is too early to draw a thoughtful conclusion. Future therapies should focus on materials and methods for sealing fetal membranes that are biocompatible, absorbable, available, easy to apply, and easily adherent to the fetal membrane.

Outcomes of Prospectively Followed Pregnancies in Rheumatoid Arthritis: A Multicenter Study from Romania.

Women with rheumatoid arthritis (RA) may carry an increased risk of adverse pregnancy outcomes (APO). The aims of this study were to compare pregnancy outcomes in RA patients as compared to the general obstetric population (GOP) and to identify a risk profile in RA. A case-control study was conducted on 82 prospectively followed pregnancies in RA and 299 pregnancies from the GOP. The mean age at conception was 31.50 ± 4.5 years, with a mean disease duration of 8.96 ± 6.3 years. The frequency of APO in RA patients was 41.5%, 18.3% experienced spontaneous abortions, 11.0% underwent preterm deliveries, 7.3% had small for gestational age infants, 4.9% experienced intrauterine growth restriction, 1.2% experienced stillbirth, and 1.2% suffered from eclampsia. The risk of APO was correlated with a maternal age higher than 35 years (p = 0.028, OR = 5.59). The rate of planned pregnancies was 76.8%, and the subfertility rate was 4.9%. Disease activity improved every trimester, and approximately 20% experienced an improvement in the second trimester. Planned pregnancies and corticosteroids use (≤10 mg daily) were protective factors for APO in RA pregnancies (p < 0.001, OR = 0.12, p = 0.016, OR = 0.19, respectively). There was no significant association between APO and disease activity or DMARDs used before and during pregnancy. Regarding the comparison between the RA group and the controls, RA mothers were significantly older (p = 0.001), had shorter pregnancies (p < 0.001), and had neonates with a lower birth weight (p < 0.001).

Platelet-Rich Plasma (PRP) in Dermatology: Cellular and Molecular Mechanisms of Action.

Platelet-rich plasma (PRP) therapy has gained attention in the scientific field due to its potential regenerative effects and great benefit-risk ratio. This review extensively explores the most studied mechanisms of this therapy according to the etiopathogenesis of skin diseases: cellular proliferation, matrix formation, regulation of inflammation, angiogenesis, collagen synthesis, and the remodeling of new tissue. Moreover, it draws on newly reported and lesser-known effects of PRP: its anti-apoptotic effects, immunological suppression, decrease in melanin synthesis, anti-microbial effects, overexpression of miR-155, antioxidant effects, and their involved pathways. This work aims to provide a complete update for understanding PRP's benefits and clinical relevance in wound healing, alopecia, pigmentary disorders, scars, rejuvenation, lichen sclerosus, and other inflammatory dermatoses, based on the current evidence. Furthermore, recent reports with novel indications for PRP therapy are highlighted, and new potential pathways correlated with the pathogenesis of skin diseases are explored.

Women's assessment of the quality of hospital-based perinatal care by mode of birth in Romania during the COVID-19 pandemic: Results from the IMAgiNE EURO study.

OBJECTIVE: To assess women's perceptions of the quality of maternal and newborn care (QMNC) received in hospitals in Romania during the COVID-19 pandemic by mode of birth. METHODS: A validated anonymous online questionnaire based on WHO quality measures. Subgroup analysis of spontaneous vaginal birth (SVB), emergency cesarean, and elective cesarean and multivariate analyses were performed, and QMNC indexes were calculated. Maternal age, educational level, year of birth, mother born in Romania, parity, type of hospital, and type of professionals assisting the birth were used for multivariate analysis. RESULTS: A total of 620 women completed the survey. Overall, several quality measures suggested gaps in QMNC in Romania, with the lowest QMNC indexes reported for provision of care and availability of resources. Women who had either elective or emergency cesarean compared with those who had SVB more frequently lacked early breastfeeding (OR 2.04 and 2.13, respectively), skin-to-skin contact (OR 1.73 and 1.75, respectively), rooming-in (OR 2.07 and 1.96, respectively), and exclusive breastfeeding at discharge (OR 2.27 and 1.64, respectively). Compared with elective cesarean, emergency cesarean had higher odds of ineffective communication by healthcare providers (OR 1.65), lack of involvement in choices (OR 1.58), insufficient emotional support (OR 2.07), and no privacy (OR 2.06). Compared with other modes of birth, a trend for lower QMNC indexes for emergency cesarean was observed for all domains, while for elective cesarean the QMNC index for provision of care was significantly lower. CONCLUSION: Quality indicators of perinatal care remain behind targets in Romania, with births by cesarean the most affected. GOV IDENTIFIER: NCT04847336.

Allergic Contact Cell-Mediated Hypersensitivity in Psoriasis: A Narrative Minireview.

The dysfunctionality of the protective skin barrier in psoriasis allows easier cutaneous penetration of various contact haptens; thus, such patients can develop allergic contact hypersensitivity as a comorbidity. Both skin conditions involve T-cell-mediated mechanisms. Dermatologists and allergists should consider assessing allergic contact cell-mediated hypersensitivity in selected psoriasis patients, especially those with palmoplantar psoriasis and who are refractory to topical treatments, and in patients with psoriasis, with or without arthritis, treated with biologics that present skin lesions clinically suggestive of contact dermatitis.

Menke-Hennekam Syndrome: A Literature Review and a New Case Report.

BACKGROUND: Menke-Hennekam syndrome (MHS) is a rare and recently described syndrome consecutive to the variants in exon 30 or 31 in CREBBP (CREB-binding protein gene). The CREB-binding protein (CREBBP) and EP300 genes are two commonly expressed genes whose products possess acetyltransferase activity for histones and various other proteins. Mutations that affect these two genes are known to cause Rubinstein-Taybi syndrome (RTS); however, with the application of whole exome sequencing (WES) there were reports of variants that affect specific regions of exon 30 or 31 of these two genes but without the specific phenotype of RTS. MATERIAL AND METHODS: A review of the available literature was conducted, aimed at underscoring the difficulties in diagnosing MHS based on phenotype particularities. RESULTS: Five applicable studies were identified by searching PubMed, Web of Science, and Scopus databases for publications up to November 2021 using the key terms "Menke-Hennekam syndrome" and "CREBBP". CONCLUSIONS: In this paper, we present a new case and highlight the importance of exome sequencing to identify different mutations of exons 30 and 31 of the CREBBP gene involved in MHS, and we make formal recommendations based on our literature review.

Smoking Obstructive Sleep Apnea: Arguments for a Distinctive Phenotype and a Personalized Intervention.

BACKGROUND: This is the first study that aims to define smoking, with obstructive sleep apnea (OSA), as a phenotype (SOSA). Moreover, we wanted to demonstrate the deleterious effects of the continuation of smoking on OSA. METHODS: The cross-sectional study highlighted four dimensions of SOSA: the demographic and anthropometric features, the symptoms, the comorbidities, and the sleep study parameters. This study compared these characteristics between current smokers (CS), those who have never smoked (NS), and ex-smokers (ES) with OSA. RESULTS: More men (83.95% in CS, versus 66.67% in NS) and an earlier onset of OSA (average age = 50.05 in CS, versus 52.26 in NS, p = 0.04) were recorded among CS. The distinguishing symptom of CS was daytime sleepiness, with an Epworth score that was significantly higher than in NS. Chronic obstructive pulmonary disease (COPD) was significantly more prevalent in CS (38.27%) than in NS (1.51%) (p < 0.001). The severity of OSA, consisting of a higher apnea-hypopnea index, a higher oxygen desaturation index, and a longer time spent below 90% oxygen saturation during sleep was significantly influenced by smoking. CONCLUSIONS: The SOSA phenotype includes younger male patients with a higher waist circumference, suggesting central obesity. They have a higher prevalence of COPD and a greater severity of OSA, in correlation with the number of pack-years of smoking.

Congenital Tarsal Kink Syndrome: Literature Review and Case Report.

BACKGROUND: The congenital tarsal kink syndrome is a rare form of congenital upper eyelid entropion associated with cardiovascular, musculoskeletal or central nervous system disorders. This syndrome must be recognized and surgically treated as a perinatal emergency to avoid associated complications-corneal ulcer, corneal leucoma, secondary amblyopia and decreased vision among children. METHODS: A literature review was conducted to clarify the diagnosis particularities and the corrective surgery options of the congenital entropion on the upper eyelid. RESULTS: Four relevant studies were found by researching the Web of Science and PubMed databases up to November 2021 for "congenital tarsal kink syndrome" and "congenital upper eyelid entropion". CONCLUSIONS: In this paper, we present a case of congenital unilateral entropion of the upper left eyelid in the context of a tarsal kink syndrome in a one-month old infant, manifested by the absence of eyelashes on the upper eyelid of the left eye, hyperlacrimation and conjunctival hyperemia. Essential in managing the upper eyelid entropion is protecting the cornea. Furthermore, correcting a tarsal kink is eminently surgical, choosing between open or closed procedures. Herein, we address the difficulty in the timely diagnosis of this uncommon condition and make formal recommendations based on all reported cases.

Severe Anaphylaxis in Pregnancy: A Systematic Review of Clinical Presentation to Determine Outcomes.

Anaphylactic reactions during pregnancy can range from subjective cutaneous symptoms to anaphylaxis and lethal anaphylactic shock. The fetal and maternal outcomes are unpredictable. This study is the first systematic review of the clinical presentation of severe anaphylaxis in pregnancy as defined by the World Allergy Organization to determine maternal and fetal outcomes. We searched PubMed, the Web of Science, and Scopus databases for articles published between 1 January 1985 and 15 April 2021 using the following terms (((anaphylactic shock) AND (pregnancy)) OR ((anaphylaxis) AND (pregnancy))). In 42 studies involving 47 patients, 36.17% of patients were 31-35 years old, and 74.47% of cases occurred peripartum, mostly during cesarean section. Accurate diagnosis with valid and reliable outcome measures was reported for 71.74% of cases. Twenty-two allergens were identified: antibiotics (penicillins and cephalosporins), anesthetic drugs (suxamethonium, mepivacaine), latex, oxytocin, sodium and sucrose iron, laminaria, misoprostol, rubber from Foley catheter, oral phytomenadione, ranitidine, chamomile, and ant sting. Two cases of maternal death related to latex and intravenous iron sucrose, and six infants with neurological disease were reported, mostly related to antibiotics. This review of the currently available literature shows that favorable outcomes are attainable with a high degree of observation, multidisciplinary cooperation, and rapid treatment.

Comprehensive Overview of Vaccination during Pregnancy in Europe.

Vaccinations during pregnancy can protect the mother from several infections, thus blocking vertical transmission. Furthermore, through passive antibody transfer, the newborn can be protected against some infections in the first months of life until their own vaccination regimen is initiated and completed at the appropriate age. Pregnancy can be considered a high-risk condition that increases vulnerability to infectious diseases with potentially unfavorable evolution. We present the current knowledge on vaccination during pregnancy in Europe as a useful information source for different health workers involved in prenatal care. Many European countries implement vaccination policies specifically designed for pregnant women, but there is great heterogeneity among programs. Recommendations on vaccination during pregnancy must be based on current high-quality scientific data. The decisions must be made for each individual case, depending on the associated conditions or special circumstances, with a concomitant assessment of the potential benefits and risks to both the pregnant patient and the fetus. Many vaccines are well-tolerated in pregnant women, with no clinically meaningful injection site reactions, systemic symptoms, or vaccine-related serious adverse events.

State-of-the-Art on Biomarkers for Anaphylaxis in Obstetrics.

Anaphylaxis is an unpredictable systemic hypersensitivity reaction and constitutes a high risk of maternal and fetal morbidity and mortality when occurring during pregnancy. Currently, the acute management of anaphylaxis is based on clinical parameters. A total serum tryptase is only used to support an accurate diagnosis. There is a need to detect other biomarkers to further assess high-risk patients in obstetrics. Our objective is to present biomarkers in this complex interdisciplinary approach beyond obstetrician and anaesthetic management. Candidate biomarkers derive either from mediators involved in immunopathogenesis or upcoming molecules from systems biology and proteomics. Serum tryptase is determined by singleplex immunoassay method and is important in the evaluation of anaphylactic mast cell degranulation but also in the assessment of other risk factors for anaphylaxis such as systemic mastocytosis. Another category of biomarkers investigates the IgE-mediated sensitization to triggers potentially involved in the etiology of anaphylaxis in pregnant women, using singleplex or multiplex immunoassays. These in vitro tests with natural extracts from foods, venoms, latex or drugs, as well as with molecular allergen components, are useful because in vivo allergy tests cannot be performed on pregnant women in such a major medical emergency due to their additional potential risk of anaphylaxis.

A Glimpse at the Size of the Fetal Liver-Is It Connected with the Evolution of Gestational Diabetes?

Gestational diabetes mellitus (GDM) is defined as an impairment of glucose tolerance, manifested by hyperglycemia, which occurs at any stage of pregnancy. GDM is more common in the third trimester of pregnancy and usually disappears after birth. It was hypothesized that the glycemic status of the mother can modulate liver development and growth early during the pregnancy. The simplest modality to monitor the evolution of GDM employs noninvasive techniques. In this category, routinely obstetrical ultrasound (OUS) examinations (simple or 2D/3D) can be employed for specific fetal measurements, such as fetal liver length (FLL) or volume (FLV). FLL and FLV may emerge as possible predictors of GDM as they positively relate to the maternal glycated hemoglobin (HbA1c) levels and to the results of the oral glucose tolerance test. The aim of this review is to offer insight into the relationship between GDM and fetal nutritional status. Risk factors for GDM and the short- and long-term outcomes of GDM pregnancies are also discussed, as well as the significance of different dietary patterns. Moreover, the review aims to fill one gap in the literature, investigating whether fetal liver growth can be used as a predictor of GDM evolution. To conclude, although studies pointed out a connection between fetal indices and GDM as useful tools in the early detection of GDM (before 23 weeks of gestation), additional research is needed to properly manage GDM and offspring health.

State-of-the-Art Review of Pregnancy-Related Psoriasis.

Psoriasis is a chronic immunologic disease involving inflammation that can target internal organs, the skin, and joints. The peak incidence occurs between the age of 30 and 40 years, which overlaps with the typical reproductive period of women. Because of comorbidities that can accompany psoriasis, including metabolic syndrome, cardiovascular involvement, and major depressive disorders, the condition is a complex one. The role of hormones during pregnancy in the lesion dynamics of psoriasis is unclear, and it is important to resolve the implications of this pathology during pregnancy are. Furthermore, treating pregnant women who have psoriasis represents a challenge as most drugs generally prescribed for this pathology are contraindicated in pregnancy because of teratogenic effects. This review covers the state of the art in psoriasis associated with pregnancy. Careful pregnancy monitoring in moderate-to-severe psoriasis vulgaris is required given the high risk of related complications in pregnancy, including pregnancy-induced hypertensive disorders, low birth weight for gestational age, and gestational diabetes. Topical corticosteroids are safe during pregnancy but effective only for localised forms of psoriasis. Monoclonal antibodies targeting cytokines specifically upregulated in psoriasis, such as ustekinumab (IL-12/23 inhibitor), secukinumab (IL-17 inhibitor) can be effective for the severe form of psoriasis during pregnancy. A multidisciplinary team must choose optimal treatment, taking into account fetal and maternal risks and benefits.

Current Evidence about Developmental Dysplasia of the Hip in Pregnancy.

In adults, developmental dysplasia of the hip (DDH) represents a spectrum of disorders. It is commonly found in women in routine orthopedic practice. Hip dysplasia is a leading precursor of joint laxity; when untreated, it can contribute to chronic modifications, such as thickening of the pulvinar and ligamentum teres (which can also elongate), hypertrophy of the transverse acetabular ligament, and osteoarthritis. DDH is presumed to be associated with alterations in pelvic morphology that may affect vaginal birth by the reduction in the transverse diameter of the pelvic inlet or outlet. Here, we provide an overview of the current knowledge of pregnancy-associated DDH. We primarily focused on how a surgical DDH treatment might influence the pelvic shape and size and the effects on the mechanism of birth. We presented the female pelvis from the standpoint of bone and ligament morphology relative to a pelvic osteotomy. Then, we described whether the pregnancy was impacted by previous surgical DDH treatments, performed from infancy to adulthood. In conclusion, hip dysplasia is not associated with high-risk complications during pregnancy or with increased difficulty in vaginal delivery.

Recommendations for a Combined Laparoscopic and Transanal Approach in Treating Deep Endometriosis of the Lower Rectum-The Rouen Technique.

The complete excision of low rectovaginal deep endometriosis is a demanding surgery associated with an increased risk of intra- and postoperative complications, which can impact the quality of life. Given the choices of optimal surgery procedures available, we would like to emphasize that a minimally invasive approach with plasma medicine and a transanal disc excision could significantly improve surgery for deep endometriosis, avoiding the lateral thermal damage of vascular and parasympathetic fibers of roots S2-S5 in the pelvic plexus. The management of low rectal deep endometriosis is distinct from other gastrointestinal-tract endometriosis nodules. Suggestions and explanations are presented for this minimal approach. These contribute to individualized medical care for deep endometriosis. In brief, a laparoscopic transanal disc excision (LTADE; Rouen technique) was performed through a laparoscopic deep rectal dissection, combined with plasma energy shaving, and followed by a transanal disc excision of the low and mid-rectal deep endometriotic nodules, with the use of a semi-circular stapler. LTADE is indicated as the first-line surgical treatment for low and mid-rectal deep endometriotic nodule excisions, because it can preserve rectal length and innervation. This technique requires a multidisciplinary team with surgical colorectal training.

Fibrosis Associated with Retroperitoneal Abscess after Multimodal Treatment of Cervical Carcinoma - A Case Report and Brief Review of the Literature.

Background: The multimodal treatment options for cervical carcinoma are represented by either radical hysterectomy associated with pelvic lymph node dissection, pelvic radiation therapy or chemotherapy. Inflammatory and post-neoplasia fibrosis associated with post-radiation fibrosis syndrome (RFS) and lymphedema may cause severe complications and quality of life alteration. Case report: Here we present a case of a 40-year-old woman, seven months after completing standard treatment for squamous cervical cancer FIGO IIA1 with a negative impact on the quality of life due to an important abdominal and retroperitoneal fibrosis leading to significant gastrointestinal symptoms. Over a year, a symptomatic intraabdominal collection and a retroperitoneal abscess were managed in the surgery department by percutaneous drainage and exploratory laparotomy. Bowel obstruction, abscessed pelvic tumor, left colocutaneous and colocolic fistula, intra-abdominal adhesions and left uretero-hydronephrosis were found. Postoperatively, the evolution was unfavorable with upper gastrointestinal bleeding probably due to entero-mesenteric fistula followed by death. Conclusion: Fibrosis can contribute to unfavorable clinical evolution with multiple complications and difficult management. Intra- and retroperitoneal fibrosis, neoplasia and post radiation enteropathy associated with pelvic inflammatory disease make the surgical approach difficult. Diagnosis of retroperitoneal abscess may be challenging due to nonspecific symptoms.

Is Metformin a Possible Beneficial Treatment for Psoriasis? A Scoping Review.

Psoriasis is a chronic inflammatory condition with genetic, immunological, and metabolic etiology. The link between psoriasis and diabetes mellitus has been shown in genetic predisposition, environmental influences, inflammatory pathways, and insulin resistance, resulting in end-organ damage in both conditions. Because comorbidities often accompany psoriasis, the therapeutic management of the disease must also take into consideration the comorbidities. Given that metformin's therapeutic role in psoriasis is not yet fully elucidated, we raised the question of whether metformin is a viable alternative for the treatment of psoriasis. We conducted this scoping review by searching for evidence in PubMed, Cochrane, and Scopus databases, and we used an extension for scoping reviews (PRISMA-ScR). Current evidence suggests that metformin is safe to use in psoriasis. Studies have shown an excellent therapeutic response to metformin in patients with psoriasis and comorbidities such as diabetes, metabolic syndrome, and obesity. There is no clear evidence supporting metformin monotherapy in patients with psoriasis without comorbidities. There is a need to further evaluate metformin in larger clinical trials, as a therapy in psoriasis.

Oral Vitamin D Therapy in Patients with Psoriasis.

Vitamin D treatment is effective when applied topically to the skin for plaque-type psoriasis. Oral vitamin D supplementation might be effective as an adjuvant treatment option in psoriasis. This umbrella review aimed to highlight the current knowledge regarding the use of oral vitamin D for treatment of patients with psoriasis. We performed a literature search and identified 107 eligible full-text articles that were relevant to the research interest. Among these, 10 review articles were selected, and data were extracted. A data synthesis showed that only a few studies monitored oral vitamin D efficacy in patients with psoriasis. No studies investigated the optimal dose of systemic vitamin D in psoriasis. However, most studies did not observe side effects for doses within a relatively narrow range (0.25 to 2 µg/day). These results suggest that more large-scale studies are needed to determine the efficacy, optimal dose, and adverse effects of vitamin D administration in patients with psoriasis.
