UNASSIGNED: Chemotherapy has increased survival rate in patients but is associated with systemic as well as cutaneous adverse effects. Among cutaneous adverse effects, nail changes caused by chemotherapy are often overlooked. But these changes are a major cause of cosmetic concern and negatively affect the quality of life (QoL) of patients.
UNASSIGNED: This study was conducted to evaluate the impact of chemotherapy-induced nail changes on QoL of patients with malignancy and to compare the severity of impact on QoL in various nail changes.
UNASSIGNED: This hospital-based cross-sectional observational study was conducted for a period of 12 months. Only patients on chemotherapy who developed nail changes were included in the study. A nail-specific QoL questionnaire was used. Statistical analysis was conducted to evaluate the impact of nail changes on QoL.
UNASSIGNED: The mean QoL score of 188 patients was 32.37 ± 7.9. The mean QoL score of females was more than that of males. QoL was statistically more significant in younger age groups [<20 years: 46.71 ± 1.7] (P < 0.001). Patients with pigmentary nail changes (melanonychia and leukonychia) had more significant impact on QoL (P < 0.001).
UNASSIGNED: There is a significant impact of chemotherapy-induced nail changes on QoL of patients leading to psychological distress, reduced self-confidence and social limitation. This highlights the importance of proper counselling of patients beforehand regarding the possibility of associated nail changes during and after the chemotherapy regimens.

OBJECTIVE: Lymphedema (LD) in Turner syndrome (TS) is a commonly reported comorbidity, though its associations with karyotype and other comorbidities are poorly understood. Characteristics of patients with TS and LD, including correlation with phenotype and karyotype, are described.
METHODS: Medical records of patients with TS seen in two pediatric institutions from 2002 to 2020 were retrospectively reviewed. Demographic data (age, presentation onset, clinical features, genetics, LD presence, investigations, treatments) were collected.
RESULTS: 393 girls with TS with mean age of 12.5 years (SD: 5.7) were identified. LD was noted in 37 % of patients (n=146). Among the 112 patients with TS and documentation of onset of LD, LD was noted within the first year of life in 78.6 % (n=88). 67.6 % (n=96) of total patients with TS and LD had non-mosaic 45, X karyotype. Frequency of webbed neck was significantly greater in girls with TS and LD compared with girls without LD (58 vs. 7 %, p<0.001). Congenital heart anomalies, hypertension, and renal anomalies were also more common in girls with LD. Nail abnormalities with presence of hypoplastic or dysplastic nails were significantly associated with LD (OR: 6.784, 95 % CI 4.235-11.046). The number of girls reporting presence of LD decreased with age.
CONCLUSIONS: LD in TS often occurs within the first year of life, is less prevalent in older children and adolescents, and is significantly associated with 45, X karyotype, presence of webbed neck, nail changes, congenital heart anomalies, and renal anomalies.

OBJECTIVE: Common side effects of taxane chemotherapy are nail toxicity and peripheral neuropathy (CIPN) causing severe impact on the quality of life. Different methods of cryotherapy to prevent these side effects have been tested. We investigated the use of machine-controlled cooling of hands and feet to reduce nail toxicity and CIPN in patients receiving taxane chemotherapy.
METHODS: Patients receiving Docetaxel (planned dose ≥ 300 mg/m2) or Paclitaxel (planned dose ≥ 720 mg/m2 - ) in the adjuvant or palliative setting of different cancers were included. The dominant hand and foot were cooled to approximately 10 °C using the Hilotherapy machine. The contralateral hand and foot were used as intrapatient comparison. The primary endpoint was the occurrence of any CIPN due to paclitaxel or nail toxicity due to Docetaxel. Both the intention to treat population (ITT) and the per protocol population (PPP) were analyzed.
RESULTS: A total of 69 patients, 21 treated with Docetaxel and 48 with Paclitaxel, were included at our centre between 08/2020 and 08/2022. Nail toxicity due to Docetaxel was overall not significantly improved by cooling in the ITT or PPP but a significant benefit across visits was found for the ITT. CIPN due to Paclitaxel was numerically better in the ITT and significantly better in the PPP. A significant benefit of cooling on CIPN occurrence across visits was found for the ITT and the PPP. Cooling was very well tolerated.
CONCLUSIONS: Cooling of hands and feet has a clinically meaningful impact on reducing occurrence of CIPN and nail toxicity on treatment with taxanes. Effects are more significant over time and are dose dependent.

Pemphigus is a group of autoimmune mucocutaneous bullous disorders characterized by acantholysis resulting from autoantibodies targeting epithelial cell surface antigens. Studies reflect the presence of nail manifestations in some patients and suggest a potential correlation with clinical severity. This study examines the overall prevalence and characterizes the diverse manifestations of nail changes in pemphigus. We searched Cochrane, MEDLINE, EMBASE, and LILACS from 1990 to June 26, 2023 for studies reporting different nail changes in pemphigus patients. Data were collected and pooled to obtain proportions of the prevalence of nail changes in patients with pemphigus and subgroup analysis for pemphigus foliaceous and pemphigus vulgaris. The risk of bias was assessed with the Joanna Briggs Institute Checklist. Of 321 studies screened, 14 studies with 1,208 patients were included. Paronychia (n = 185) and Beau\'s lines (n = 104) were the most common nail changes identified. The pooled prevalence of nail disease in pemphigus patients was 0.389 (number of studies; [95% CI]: n = 9; [0.160-0.680], with high heterogeneity between studies (I2 = 95.0%, P < 0.001). Subgroup analysis revealed the highest prevalence in pemphigus foliaceous at 0.342 (n = 3; [0.109-0.688]) and pemphigus vulgaris at 0.396 (n = 5; [0.114-0.769]). Nail changes exhibited varied temporal relationships with disease onset and flares, preceding, concurrent, or following these events. Correlation with disease severity was noted, although discrepancies between studies were reported. Nail changes in pemphigus, particularly pemphigus vulgaris and pemphigus foliaceous, may be underrecognized. Observations regarding temporal associations and potential correlations with disease severity highlight the diagnostic and prognostic implications of nail changes in pemphigus. The limitations of this study include study heterogeneity and possible bias. Further research to establish the correlation of the presence and severity of nail changes on the overall disease course would be helpful.

UNASSIGNED: Alopecia areata (AA) is an immune-mediated nonscarring alopecia. Nail changes are a common disfiguring feature of AA with an average prevalence of 30%. We aimed to evaluate the frequency of different types of nail changes and determine demographic and clinical associations.
UNASSIGNED: This cross-sectional study included 197 AA patients. Demographic and clinical variables including the Severity of Alopecia Tool (SALT) score, type of AA, and nail changes were evaluated.
UNASSIGNED: Among 197 AA patients with a mean age of 28.95 ± 14.45 years, 50.3% were female. Nail changes were detected in 165 patients (83.8%). The most frequent nail abnormalities were pitting (53.3%), linear line (46.7%), and distal notching (26.9%). AA patients with nail abnormalities were significantly younger than patients without nail changes (25.31 ± 14.96 vs. 32.22 ± 9.77 years; p < 0.001). Considering age groups, younger children (less than 10 years) were more likely to have nail changes than adults (97.1% vs. 76.5%; p < 0.001). The prevalence of linear line (69.6%) and distal notching (46.4%) were significantly higher in the universalis variant compared to other variants (p < 0.001). Pitting (54.5%), distal notching (43.9%), and koilonychia (12.1%) were the most common nail changes in severe forms compared to mild-to-moderate forms (p < 0.009).
UNASSIGNED: Our study revealed that young patients with severe disease are prone to nail abnormalities. Pitting, distal notching, and linear line were the most common nail changes. Of note, koilonychia, leukonychia, and red spots lunula are more expected in more severe AA.

BACKGROUND: Leprosy is a chronic granulomatous infectious disease, mainly affecting the skin and peripheral nerves, caused by the obligate intracellular bacteria Mycobacterium leprae. The disease has been discussed in several review articles in recent research, but as far as we know, only a few have addressed the effects of leprosy on nails, especially those who examine the dermoscopic features of nails in leprosy patients.
OBJECTIVE: We aimed to document nail changes in leprosy patients and identify any particular findings through dermoscopic examination.
METHODS: This was an observational study conducted in the Dermatology and Venereology Clinic of Hasan Sadikin Hospital, West Java, Indonesia, from March 2023 through May 2023. All patients have established cases of leprosy, and the diagnosis is based on clinical and bacteriological examinations. Recruitment was done through total sampling. Dermoscopic examination of all fingernails and toenails was performed at 10x magnification using a handheld dermatoscope (Heine DELTA 20 T Dermatoscope) in polarized mode without the linkage fluid to document the dermoscopic features.
RESULTS: Of a total of 19 patients, 15 had nail changes due to leprosy. Out of 15 patients, 13 patients were male. Patients below 25 years old had more nail changes. Most of the patients had a duration of disease greater than two years. Both fingers and toes were involved in nine patients. In this study, the most common dermoscopic feature found was the longitudinal ridge. Other dermoscopic features found in this study were transverse lines, onycholysis, longitudinal melanonychia, leukonychia, subungual hemorrhage, subungual hyperkeratosis, anonychia, and onychorrexis.
CONCLUSIONS: Nail changes are found in leprosy patients and have a wide variety of clinical appearances. A dermoscopy should be performed to assess nail changes in leprosy.

Pemphigus vulgaris (PV) mainly causes blistering of the skin and mucous membranes, with nail unit involvement being rare. Nail involvement may serve as an indicator of disease severity. We present a case of a 20-year-old male with PV who had both cutaneous and nail findings, with nail changes corresponding with disease severity. The patient with biopsy-confirmed PV, on prednisone and mycophenolate, presented to the emergency department with an acute flare of PV and severe mandibular pain and lymphadenopathy. At follow-up in our outpatient department, the physical examination was significant for onychomadesis and onycholysis of the fingernails. Prednisone and mycophenolate dosages were increased, and rituximab infusions were initiated. Bullae and mucosal lesions resolved on the follow-up, and nail changes improved. This case appends an unusual perspective to the limited literature on PV-associated nail changes, especially in younger patients. It advocates for meticulous history taking and physical examination and supports a correlation between nail symptoms and PV disease severity.

UNASSIGNED: Autoimmune blistering (AIBD) disorders affect mucosae, skin, and appendages. Appendageal involvement has not been studied extensively to date. However, they are important as nail changes are commonly encountered during a flare-up of the disease.
UNASSIGNED: To determine the prevalence and patterns of nail changes in various Immunobullous disorders and to study the relationship between the nail changes and the disease duration and severity.
UNASSIGNED: A cross-sectional study was conducted at the Department of Dermatology, venerology, and leprosy at a tertiary care center in Mumbai.
UNASSIGNED: A cross-sectional study including a total of 74 cases of Immunobullous diseases was conducted and the prevalence of nail changes was determined. The association between the mean number of nail changes and the disease duration and severity was analyzed using ANOVA (Analysis of variance) and unpaired t-test.
UNASSIGNED: The Statistical Package for Social Studies (SPSS) software was used for statistical evaluation.
UNASSIGNED: We found that the prevalence of nail changes was 91%. There was a significant difference in the mean number of nail changes with respect to the severity grades of mucosal involvement in AIBD (P value < 0.05). There was no significant difference in the mean number of nail changes with respect to the severity grades of Pemphigus vulgaris (PV), Pemphigus foliaceous (PF), subepidermal blistering diseases, and the duration of AIBD.
UNASSIGNED: Nails are frequently affected in AIBD. The number of nail changes is related to the severity of mucosal disease but not to duration.
