ABSTRACT
OBJECTIVES: The existence of standard methods for diagnosis and measuring the severity of diseases leads to a more accurate severity assessment, the possibility of following up, and the possibility of comparing the results of studies. This study aimed to compare different pemphigus vulgaris (PV) assessment methods regarding inter-observer reliability and testing times-focusing on oral parts. MATERIALS AND METHODS: Two dermatologists evaluated orally involved PV patients by oral parts of Autoimmune Bullous Skin Disorder Intensity Score (ABSIS), Pemphigus Disease Area Index (PDAI), and Oral Disease Severity Score (ODSS). RESULTS: Seventy patients completed the study. The intraclass correlation coefficient showed the evaluators' agreements on ABSIS, PDAI, and ODSS with 0.98, 0.94, and 0.95, respectively. Reliability analyses showed near-perfect relationships between each scoring methods pairs. There was no association between lesion sites and disease severity. The PDAI scoring duration was significantly shorter, and the ABSIS scoring duration was significantly longer. CONCLUSION: ODSS is valid for evaluating oral involvement in patients with PV and relates to ABSIS and PDAI almost perfectly. Besides, it was shown that the evaluation of patients' oral involvement based on PDAI and ODSS is done in about 1 min, which seems clinically reasonable.

Pemphigus is a group of autoimmune diseases characterized by flaccid lesions on the skin and mucous membranes. In pemphigus vulgaris, the most common subtype of pemphigus, lesions might be appeared anywhere on the oral mucosa, mostly in the buccal mucosa. However, the gingiva is a less frequently affected site. Here, we performed a retrospective study at Tehran University of Medical Sciences, covering a two-year period to identify pemphigus patients with active lesions confined to the gingiva. Considering 1787 initially evaluated pemphigus cases, 512 (28.6%) were found to have a history of gingival involvement. Among them, 31 patients had only gingival involvement during their last visit, including 29 (93.5%) women and only two (6.5%) men. The mean of disease duration in this group was 5.29 ± 3.46 years, and they had gingival involvement for a mean of 23.9 ± 19.3 months. Of 28 patients, nine were negative for anti-Dsg3 and 24 were negative for anti-Dsg1. In 24 patients, who received rituximab, the mean pemphigus disease area index specifically for gingiva was 4.76 ± 0.74 at baseline, which had changed to 4.13 ± 0.75 and 3.26 ± 0.63 three and 6 months after rituximab administration, respectively. After 3 months, gingival lesions were either entirely resolved (n = 3), partially resolved (n = 11), remained unchanged (n = 2), or progressed (n = 7). Gingiva-confined presentation of lesions in pemphigus could be non-anti-Dsg1/3 dependent in some patients. Such patients do not respond well to conventional treatments and rituximab therapy. More studies on the pathogenesis of gingiva-confined presentation of pemphigus are required.

BACKGROUND: Scars are inevitable results of surgical procedures, and prevention of them is still a major problem in the field of cosmetic surgery. Although various studies have been performed on botulinum toxin-A (BoNT-A) injection for the prevention of hypertrophic scars, the exact mechanism remains unclear. METHODS: This prospective, double-blinded, randomized study was performed on 19 patients who underwent mammoplasty and abdominoplasty surgery in Razi Hospital from October 2018 to December 2019. Single session of treatment was performed, where XEOMIN was allocated to one half of the scar and 0.9% saline to the control half. 3 and 6 months later, scars were assessed using the modified Stony Brook Scar Evaluation Scale (SBSES). RESULTS: In total, 19 patients who completed the study were analyzed. mSBSES at the third month (P value < 0.001; 3.34 ± 1.59 vs 1.5 ± 1.36) and the sixth month (P value < 0.001; 4.89 ± 1.83 vs 2.39 ± 1.82) showed a significant difference between the treatment and control groups. In the subset analysis, there was significant difference between BoNT-A and control in all four items including width, height, color, and scar visibility at months 3 and 6, and the BoNT-A-treated sides had higher scores in all items. CONCLUSION: BoNT-A has a significant effect on scar prevention due to mammoplasty and abdominoplasty compared to placebo and results in decreased erythema, height, width and reduces incision line visibility. Moreover, its effect increases significantly over time from months 3 to 6. LEVEL OF EVIDENCE II: This journal requires that authors assign a level of evidence to each article.

The effect of thermotherapy in the treatment of skin warts in comparison to cryotherapy, as the standard conventional method, has remained uncertain. This study aimed to assess the clinical efficacy and safety of thermotherapy and cryotherapy in removing skin warts. This randomized controlled trial was conducted on 52 patients aged 18 years and over with ≤ 10 skin warts. The participants were randomly assigned into two groups to receive cryotherapy (every 2 to 3 weeks up to six sessions if required) or thermotherapy (one session). The patients in both groups were followed every 2 to 3 weeks for the first three months, and then three months after the last treatment session. The clearance rate was 79.2% in the thermotherapy group and 58.3% in the cryotherapy group with no significant difference (p = 0.212). The rate of scarring in the thermotherapy group was 20% (p = .018). A higher clearance rate was achieved in the thermotherapy group. However, this result was not statistically significant. There were some minimal post-treatment complications. Patients needed only one session of thermotherapy. Due to the risk of scarring, we suggest thermotherapy only as a suitable treatment method for palmoplantar warts.

BACKGROUND: Alopecia areata (AA) is a recurrent immune-mediated disorder causing hair loss without any scarring being present. It affects hairs on the head or other parts of the body and can occur at any age and in both genders. It seems that AA is associated with a higher rate of psychological disorders resulting from hair loss and the esthetic and social repercussions of it. Common treatments like corticosteroids do not work for every patient and recent treatment options focusing on the immunologic mechanisms like tofacitinib have shown some promising results. METHODS: It's a retrospective study on patients with AA, AT, AU taking oral tofacitinib as a treatment for at least 6 months. Scalp hair loss was assessed before treatment and at each visit using the Severity of Alopecia Tool (SALT) score. RESULTS: Of 97 cases, 69.1% demonstrated over 50% SALT score improvement, with 44.3% having 90% or more decrease in SALT score. Patients who suffered from patchy AA were more responsive compared to patients with AT and AU subtypes and had a greater percent change in SALT score. Tofacitinib was tolerated quite well and no significant adverse events were reported. CONCLUSIONS: Tofacitinib should be taken into consideration as an efficacious treatment option for patients with AA, AT and AU.

Pemphigus encompasses a rare heterogeneous group of autoimmune blistering diseases characterized by cutaneous and/or mucosal blistering. Multiple factors, such as some specific types of drugs, have been found to be involved in the induction of pemphigus. Here, we have designed a systematic review by searching PubMed/Medline and Embase databases to find the drugs, involved in pemphigus induction and exacerbation (updated on 19 August 2019). From 1856 initially found articles, 134 studies (198 patients; 170 patients in the drug-induced patients and 28 in exacerbation group) have been included. Regarding drug-induced cases, the mean age was 57.19 ± 16.9-year-old (ranged 8-105), and patients had developed pemphigus within a mean of 154.27 days. Pemphigus vulgaris (38.9%), pemphigus foliaceus (33.5%), and paraneoplastic pemphigus (3.6%) were the most common subtypes. Furthermore, penicillamine (33.1%), captopril (7.7%), and bucillamine (6.5%) were the most reported drugs related to pemphigus induction; penicillamine was associated with the most persistent disease. Regardless of disease subtype, cutaneous, mucocutaneous, and mucosal involvements were reported in 68.6%, 30.1%, and 1.3% of patients, respectively. In total, the IgG deposition in the pathological studies, being positive for autoreactive antibodies in the serum against desmoglein 3 (Dsg3), and desmoglein 1 (Dsg1), were reported in 93%, 34.9%, and 72.7% of reported patients, respectively. Regarding the management of such patients, in 75% of healed cases, treatment (mainly transient systemic and topical corticosteroids and/or azathioprine) was needed besides stopping the probable pemphigus-inducing culprit drug, while drug cessation was enough to control the disease in 25%. As the outcomes, the lesions in 129 of 147 (87.8%) patients had been healed, while in 18 (12.2%), no healing was reported; fifteen out of 18 had died. In conclusion, some specific groups of treatments can induce pemphigus, including penicillamine, captopril, and bucillamine; despite the similar clinical and pathological manifestations to classical pemphigus, most of the cases are less severe and have a better prognosis.

OBJECTIVE: Psoriasis is a chronic inflammatory disorder, which is associated with high risk of metabolic comorbidities. Hypertension (HTN) is among the most common and serious associations. In this study, we aimed to evaluate HTN in psoriatic patients through office and ambulatory blood pressure monitoring (ABPM). MATERIALS AND METHODS: Forty-nine patients with confirmed diagnosis of psoriasis were enrolled in the study. Office measurement of blood pressure was performed and then holter monitoring was used for 24-h ABPM. RESULTS: Thirty-six patients (73.4%) had HTN including 13 females (36.1%) and 23 males (63.9%) (P = 0.011). Twelve patients (33.3%) had masked HTN (six females and six males). Office, 24-h, morning, daytime, and nocturnal HTN were present in 49%, 40.8%, 34.7%, 36.7%, and 63.3% of our patients, respectively. The only factor significantly related to morning/daytime/24 h HTN was age, which hypertensive patients had higher age. About 22.4% of patients had metabolic syndrome, which was significantly associated with FBS, weight, waist circumference, and BMI. CONCLUSION: Psoriasis is associated with a high rate of HTN. Masked HTN constitutes nearly one-third of hypertensive patients. ABPM increases the accuracy of HTN detection in psoriatic patients.

BACKGROUND: Distinction between alopecia areata (AA) and androgenic alopecia (AGA) can be made according to clinical presentation and biopsy findings. However, it is sometimes difficult to differentiate them, especially when the diffuse pattern of both AA and AGA is in the differential diagnosis of hair loss in androgen-dependent areas. OBJECTIVES: To evaluate the characteristics of inflammatory cell infiltration using CD3, CD4, CD8, and CD20 antigens, in AA and AGA to find some consistent histological clues for distinguishing these two entities. METHODS: A retrospective analysis of patients with diagnosed AA (30 cases) and AGA (30 cases) was performed based on the clinical and histopathological criteria. We studied immunohistochemical findings for CD3, CD4, CD8, and CD20 in all selected cases. RESULTS: Immunohistochemical stains for CD4 and CD20 were not helpful in differentiating AA from AGA, but the inflammation density for AA was significantly (P-value = .025, .001) higher than AGA in CD3 (specificity= 86.7% and sensitivity= 96.7%) and CD8 (specificity= 50% and sensitivity=86.6%). Our findings revealed that intrafollicular CD3 (P-value = .017) and CD8 (P-value = Ë.001) infiltrations were significantly higher in AA samples in comparison with AGA. CONCLUSION: Characterization of CD3 and CD8 in IHC samples is helpful, especially when the density of CD3 and CD8 T cells are significant in more than 50% of the infiltrated cells and are located intrafolliculary. Moreover, the most specific and sensitive test for differentiating of AA from AGA is CD3.

BACKGROUND: Keloids and hypertrophic scars are due to overgrowth of dermal collagen following trauma to the skin that usually cause major physical, psychological and cosmetic problems. METHODS: In this randomized controlled trial, with a paired design, 50 patients with 2 or more keloids were included. In the control group (50 lesions), intralesional triamcinolone acetonide (40mg/mL) was injected at three-week intervals for a total of 18weeks. In the other group (50 lesions), lesions were treated by verapamil (2.5mg/mL) with the same therapeutic sessions. Scar evaluation at each stage and at the end of 3months follow up was done by serial photographic records as well as by Vancouver Scar Scale (VSS). RESULTS: Mean zero VSS scores were achieved with only triamcinolone in respect of scar height (week 15th) and pliability (week 15th). No therapeutic event (parameter=0) or significant improvement was seen in verapamil group. CONCLUSION: Our results did not support verapamil's capability in treatment of keloid nor hypertrophic scars.

OBJECTIVE: To examine early performance on an eye surgery simulator and its relationship to subsequent live surgical performance in a single large residency program. DESIGN: Retrospective study. SETTING: Massachusetts Eye and Ear, Harvard Medical School, Department of Ophthalmology. METHODS: In a retrospective study, we compared performance of 30 first-year ophthalmology residents on an eye surgery simulator to their surgical skills as third-year residents. Variables collected from the eye surgery simulator included scores on the following modules of the simulator (Eyesi, VRmagic, Mannheim, Germany): antitremor training level 1, bimanual training level 1, capsulorhexis level 1 (configured), forceps training level 1, and navigation training level 1. Subsequent surgical performance was assessed using the total number of phacoemulsification cataract surgery cases for each resident, as well as the number performed as surgeon during residency and scores on global rating assessment of skills in intraocular surgery (GRASIS) scales during the third year of residency. Spearman correlation coefficients were calculated between each of the simulator performance and subsequent surgical performance variables. We also compared variables in a small group of residents who needed extra help in learning cataract surgery to the other residents in the study. MAIN OUTCOME MEASURES: Relationships between Eyesi scores early in residency and surgical performance measures in the final year of residency. RESULTS: A total of 30 residents had Eyesi data from their first year of residency and had already graduated so that all subsequent surgical performance data were available. There was a significant correlation between capsulorhexis task score on the simulator and total surgeries (r = 0.745, p = 0.008). There was a significant correlation between antitremor training level 1 (r = 0.554, p = 0.040), and forceps training level 1 (r = 0.622, p = 0.023) with primary surgery numbers. There was a significant correlation between forceps training level 1 (r = 0.811, p = 0.002), and navigation training level 1 (r = 0.692, p = 0.013) with total GRASIS score. There was a significant inverse correlation between total GRASIS score and residents in need of extra help (r = -0.358, p = 0.003). CONCLUSION: Module scores on an eye surgery simulator early in residency may predict a resident׳s future performance in the operating room. These scores may allow early identification of residents in need of supplemental training in cataract surgery.

BACKGROUND: Gastric cancer is considered as the second most prevalent cancer in Iran. The present research sought to identify high risk clusters of gastric cancer with mapping using space-time scan statistics. MATERIALS AND METHODS: The present research is of descriptive type. The required data were gathered from the registered cancer reports of Cancer Control Office in the Center for Non Communicable Disease of the Ministry of Health (MOH). The data were extracted at province level in the time span of 2004-9. Sat-Scan software was used to analyse the data and to identify high risk clusters. ArcGIS10 was utilized to map the distribution of gastric cancer and to demonstrate high risk clusters. RESULTS: The most likely clusters were found in Ardabil, Gilan, Zanjan, East-Azerbaijan, Qazvin, West-Azerbaijan, Kurdistan, Hamadan, Tehran and Mazandaran between 2007 and 2009. It was statistically significant at the p-value below 0.05. CONCLUSIONS: High risk regions included Northern, West-North and central provinces, particularly Ardabil, Kurdistan, Mazandaran and Gilan. More screening tests are suggested to be conducted in high risk regions along with more frequent epidemiological studies to enact gastric cancer prevention programs.
