This study found that all 26 patients with specific skin lesions, primarily young females, were confirmed to have iron deficiency anemia after ruling out other possible causes such as zinc deficiency and pellagra, highlighting the importance of considering anemia as a diagnosis in such cases.

This case report describes a patient with a hepatitis C diagnosis whose acral rash, initially unresponsive to psoriasis treatment, showed significant improvement with oral zinc sulfate, suggesting a diagnosis of necrolytic acral erythema.

This report found follicular red dots in patients with scalp pigmentary disorders, suggesting they might be linked to the scalp's vascular structure and may have implications for conditions like discoid lupus erythematosus.

This article discusses the potential for hypervitaminosis A in patients with chronic renal disease undergoing dialysis, highlighting the risks associated with low-dose vitamin A supplementation, and reports no new clinical results.

This article describes a case of localized trichorrhexis nodosa in a patient with otherwise normal hair, highlighting the condition's response to trauma and diagnostic process but reporting no new clinical findings.

The conclusion is that different blood diseases cause specific oral symptoms and require varied treatments to manage these symptoms and improve patient health.

This study found that while iron supplements are generally well tolerated by patients with anemia, their clinical benefit in those without iron deficiency is modest.

This study found that Chinese female patients with systemic autoimmune diseases treated intravenously with cyclophosphamide were more likely to experience gastrointestinal discomfort, myelosuppression, and alopecia.

This study found that participants with normal hemoglobin but low ferritin experienced significantly more symptoms like restless leg syndrome, dizziness, and shortness of breath compared to those with normal ferritin.

This case report describes the first known instance of alopecia associated with multicentric reticulohistiocytosis, evidenced by scalp biopsy findings of histiocyte infiltration in a 52-year-old woman.

This review clarifies that non-anaemic iron deficiency in non-pregnant premenopausal women often arises from menstrual iron losses and can cause symptoms like hair loss, while in post-menopausal women and adult men, iron deficiency anaemia frequently indicates chronic intestinal bleeding.

This case report illustrates that pellagra can develop in patients with anorexia nervosa without typical signs of severe malnutrition, responding rapidly to nicotinamide and tryptophan therapy.

This review examines the role of red cell distribution width and its association with iron metabolism and other factors in diagnosing and monitoring various anemic and non-anemic conditions, reporting no new clinical findings.

This study observed that diffuse alopecia is the most common type of non-cicatricial alopecia in females and is significantly associated with connective tissue diseases, use of certain medications, and lower blood hemoglobin levels.

In this study, researchers used trichoscopy to establish standardized findings for normal hair and scalp characteristics in 360 healthy males, noting significant age-related differences in hair diameter variability and identifying potential pathological indicators like colored dots and scarring not present in healthy individuals.

This review discusses cutaneous extramedullary haematopoiesis and its potential mechanisms but reports no new clinical findings.

This letter reports that normal iron levels were observed in women with androgenetic alopecia, suggesting the condition may not be related to iron deficiency.

This study observed that CDH3-related congenital hypotrichosis with juvenile macular dystrophy presents with childhood-onset progressive chorioretinal atrophy and universally thin and sparse scalp hair.

This article discusses the case of a patient on long-term renal dialysis with high serum vitamin A levels likely due to inadequate removal during dialysis, highlighting the need to reassess vitamin A supplementation in such patients.

This study found that ferritin and cobalamin levels were better indicators than hemoglobin in assessing chronic nonscarring hair loss in females of reproductive age.

In this case study, researchers documented a Chinese boy with hair color changing to red and identified MC1R genetic mutations as the cause, rather than zinc deficiency, enhancing our understanding of hair heterochromia due to genetic factors.

This report describes a case of HAIR-AN syndrome in a young woman, characterized by acanthosis nigricans, insulin resistance, and polycystic ovaries, highlighting its rarity and multisystem nature.

This case report highlights a rare presentation of acute lupus hemophagocytic syndrome with initially negative antinuclear antibodies, underscoring the higher sensitivity of the 2012 Systemic Lupus International Collaborating Clinics criteria for diagnosis.

This review explores hair signs related to nutrition disorders, such as thin and dyspigmented hair, without presenting new clinical findings; the authors highlight unknowns regarding underlying causes.

In this case report, a 42-year-old male diagnosed with Cronkhite-Canada syndrome presented symptoms like chronic diarrhea, significant weight loss, skin hyperpigmentation, alopecia, and nail dystrophy, with endoscopic findings revealing numerous gastrointestinal polyps.

This case report presents a rare instance of recurrent ACTH-independent Cushing’s syndrome due to PBMAH, coinciding with the development of a pheochromocytoma, highlighting the need for thorough reevaluation in similar recurring cases.

This case study reported normal hair structure under polarized light microscopy in a 70-year-old man with zinc deficiency, contrasting with previous findings in acrodermatitis enteropathica.

This case report details an atypical presentation of Hodgkin's lymphoma in an 87-year-old man, where severe hypercalcemia and mental status changes prompted further investigation and diagnosis.

In this study, non-anemic menstruating women with iron deficiency showed significant associations with symptoms such as recent hair loss at serum ferritin levels ≤ 20 µg/l and restless legs syndrome at levels ≤ 50 µg/l.

This study found that patients with alopecia areata have a significantly higher risk of retinal abnormalities, suggesting common immune mechanisms, though the low absolute risk indicates that screening should be led by symptoms rather than done routinely.
