Chromhidrosis due to exogenous oxidizing heavy metals: Clinical and laboratory findings.

BACKGROUND/OBJECTIVES: Chromhidrosis is a rare condition of which there are only a few case reports in the literature. The aim of this study was to evaluate clinical, laboratory, and possible environmental factors in 13 patients with chromhidrosis to elucidate causative agents. METHODS: Data were obtained from the medical records of 13 patients with colored sweating between October 2015 and November 2016 (7 infants <1 year of age, 5 adults, 1 adolescent). RESULTS: Physical examination was normal in all patients. Nine of 12 had high calculated serum free copper (75%). Urine glutamine was measured in 13 patients and was high in 11 (84.6%). Ten patients drank natural mineral water from Uludag Mountain, and two were exposed to an intrauterine device containing copper. One patient (8%) was not exposed to Uludag Mountain natural water or an intrauterine device. CONCLUSION: We propose that chronic exposure to water or devices that contain high amounts of heavy metal and ammonium may contribute to CH.

Eccrine Chromhidrosis in an Adolescent with Sickle Cell Disease.

Eccrine chromhidrosis can occur secondary to hyperbilirubinemia. We report an adolescent with sickle cell disease who presented with eccrine chromhidrosis on his palmar and plantar surfaces. He had extremely high levels of conjugated bilirubin but no fever. This is the youngest known reported patient with eccrine chromhidrosis and the first in a patient with sickle cell disease.

Sympathetic cardiovascular and sudomotor functions are frequently affected in early multiple sclerosis.

OBJECTIVE: The aim of this study was to determine the prevalence of autonomic dysfunction using the composite autonomic scoring scale (CASS) and heart rate variability (HRV) in patients with clinically isolated syndrome (CIS) and to correlate autonomic dysfunction with other measures of MS disease activity. METHODS: CASS, HRV and plasma catecholamines during supine and tilted phase were performed in 104 CIS patients. MRI findings were analyzed for total number of lesions and the presence of brainstem and cervical spinal cord lesions. RESULTS: Autonomic dysfunction (CASS >1) was present in 59.8 % of patients, parasympathetic dysfunction in 5 %, sympathetic in 42.6 % and sudomotor in 32.7 % of patients. Patients with autonomic dysfunction on CASS had lower level of norepinephrine in the supine position compared to patients without autonomic dysfunction (1.06 ± 0.53 vs. 1.37 ± 0.86, p = 0.048). The CASS score showed positive correlation with s-HF (r = 0.226, p = 0.031), s-SDNN (r = 0.221, p = 0.035), t-HF (r = 0.225, p = 0.032), and t-HFnu (r = 0.216, p = 0.04), and a negative correlation with t-LF/HF (r = -0.218, p = 0.038). More patients with MRI brainstem lesions had a positive adrenergic index (p = 0.038). Patients with MRI brainstem lesions also had a lower t-SDNN (26.2 ± 14.2 vs. 32 ± 13.3, p = 0.036) and a lower t-LF (median 415.0 vs. 575.5, p = 0.018) compared to patients without these lesions. Patients with adrenergic index ≥1 had a significantly higher standing heart rate compared to patients with an adrenergic index of 0 (96 ± 13.5 vs. 90 ± 12, p = 0.032). CONCLUSION: Autonomic (primarily sympathetic) dysfunction is present in a large proportion of early MS patients and it seems to be related to brainstem involvement.

Enlargement of eccrine angiomatous hamartoma following trauma.

Eccrine angiomatous hamartoma (EAH) is a rare, benign hamartoma of eccrine and vascular components that predominantly affects children. Growth is typically commensurate with the child's growth. Herein we report an additional case of this rare entity that enlarged after trauma in a 7-year-old girl.

A curious case of blue-green discoloration in a middle-aged indian man: Chromhidrosis.

INTRODUCTION: Chromhidrosis is a rare sweat gland disorder characterized by the excretion of colored sweat. It can be classified as apocrine, true eccrine, and pseudochromhidrosis. Amongst the different types of chromhidrosis, green chromhidrosis is extremely rare. We describe herein a case of blue green chromhidrosis induced by ingestion of homeopathic medicine. CASE REPORT: A middle aged man presented to us with blue green discoloration of hands and feet. There was a preceding history of ingestion of homeopathic medication. Histopathology from the involved skin showed greenish particles within eccrine glands. Initial blood copper level was high which returned to normal level after discontinuation of the homeopathic medicine. Spectrophotometry revealed high copper content of the green sweat. CONCLUSION: Our case emphasizes the importance of considering any type of ingested medicine, including homeopathic medicine, as a probable cause of chromhidrosis.

A case of generalized red sweating.

We report a case of a 70-year-old man with a 5-year history of red pigmented sweating on the axillae, groin, forearms, trunk, and and peri-nuchal sites. No identifiable cause of the pigmented sweat was identified. Biopsy revealed lipofuscin pigment leading to the diagnosis of idiopathic chromhidrosis. This case represents an unusual presentation of chromhidrosis that was not limited to the apocrine sweat gland distribution and ultimately revealed no identifiable cause. After failing multiple treatment options, the patient elected for a trial of treatment with 20% aluminum chloride solution.

Eccrine chromhidrosis secondary to hyperbilirubinemia.

BACKGROUND: Eccrine chromhidrosis, or colored eccrine sweating, may be caused by contamination of sweat by dyes, pigmentation from microorganisms, or more rarely, hyperbilirubinemia. Pigment usually affects the palms and soles, where abundant sweat glands are found.Purpose, Material and Methods: We report a unique case of eccrine chromhidrosis in the setting of hyperbilirubinemia and review the current literature available on PubMed of previously reported cases. RESULTS: Six patients with chromhidrosis have been previously reported in the setting of significant hyperbilirubinemia, in association with fever and thickened stratum corneum. CONCLUSIONS: Eccrine chromhidrosis secondary to hyperbilirubinemia is very rare, but can be diagnosed on the basis of classic clinical findings, dermoscopic examination, and negative tissue cultures.

Skin hygiene for patients with bariatric needs.

Patients with bariatric needs are likely to experience skin problems because maintaining skin hygiene, particularly between skin folds, can be a challenge. This article is a summary of a literature review that explored the evidence on skin hygiene for people with bariatric needs. The findings reveal a gap in the evidence base and the authors make several recommendations for further research.

Functional characterization of variants in human ABCC11, an axillary osmidrosis risk factor.

Human ATP-binding cassette transporter C11 (ABCC11) is a membrane protein exhibiting ATP-dependent transport activity for a variety of lipophilic anions including endogenous substances and xenobiotics such as anti-cancer agents. Accumulating evidence indicates that ABCC11 wild type is responsible for the high-secretion phenotypes in human apocrine glands including wet type of earwax and the risk of axillary osmidrosis. Also, a less-functional variant of ABCC11 was reportedly associated with a risk for drug-induced toxicity in humans. Thus, functional change in ABCC11 may affect individual's constitution and drug toxicity, which led us to reason that functional validation of genetic variations in ABCC11 should be of importance. Therefore, in addition to p.G180R (a well-characterized non-functional variant of ABCC11), we studied cellular expression and function of 10 variants of ABCC11. In this study, ABCC11 function was evaluated as an ATP-dependent transport of radio labeled-dehydroepiandrosterone sulfate using ABCC11-expressing plasma membrane vesicles. Except for p.G180R, other 10 variants were maturated as an N-linked glycoprotein and expressed on the plasma membrane. We found that six variants impaired the net cellular function of ABCC11. Among them, p.R630W was most influential. Including this identification of a significantly-dysfunctional variant, our findings will extend our understanding of genetic variations and biochemical features of ABCC11 protein.

Eccrine squamous syringometaplasia secondary to cutaneous extravasation of docetaxel: report of three cases.

Eccrine squamous syringometaplasia is characterized by the metaplasia of cuboidal epithelial cells of the eccrine sweat ducts into squamous epithelial cells. It has been associated with several conditions including chemotherapy-related bilateral dermatitis, an entity that can take place in body areas rich in eccrine glands, as well as in acral erythema related to chemotherapy. Only a few cases because of cutaneous extravasation of chemotherapy have been previously reported. We report three cases of eccrine squamous syringometaplasia secondary to extravasation of docetaxel.

Reduction in QSART and vasoactive intestinal polypeptide expression in the skin of Parkinson's disease patients and its relation to dyshidrosis.

BACKGROUND: With regards to dyshidrosis in Parkinson's disease (PD), there is no established and consistent view on the occurrence sites, frequency and etiology, although there have been several reports on hypohidrosis of the limbs and sudoresis on the face/cervical region. METHODS: Hydrosis in the forearms of PD patients and healthy individuals were compared by quantitative sudomotor axon reflex test (QSART). The expression of various neuropeptides and alpha-synuclein was examined with immunohistochemical staining. RESULTS: There was a significant reduction in QSART of PD patients but not of healthy controls. Reduced expression of vasoactive intestinal polypeptide (VIP) was also detected in the sweat glands of PD patients. CONCLUSION: Reduction in QSART and VIP expression in the sweat glands might be involved in the dyshidrosis of PD patients.

Eccrine angiomatous hamartoma: a rare multifocal variant with features suggesting trauma.

Eccrine angiomatous hamartoma (EAH) is a rare, benign cutaneous tumor characterized by proliferation of the eccrine gland elements closely associated with capillary angiomatosis and proliferation of other dermal elements, such as adipose tissue, hair and epidermis. Patients usually present with a solitary nodule on the extremities appearing at birth or during the prepubertal years. However multifocal lesions or late onset of this condition may occur. Eccrine angiomatous hamartoma is usually sporadic, but one familial case of the multifocal variant has been reported. The clinical presentation ranges from a simple angiomatous nodule to erythematous--purpuric plaques. Eccrine angiomatous hamartoma is generally asymptomatic but may occasionally be associated with pain and hyperhidrosis. We report a rare case of the multifocal variant of EAH in a 13-year-old girl, with histological features suggesting trauma. Clinically, this condition must be differentiated from other angiomatoses and a definitive diagnosis is based upon histology. Eccrine angiomatous hamartoma is a benign slowly growing lesion for which aggressive treatment is not indicated. Simple excision is reserved for painful or cosmetically disfiguring examples.

Treatment of menopausal symptoms with Er-xian decoction: a systematic review.

The purpose of this systemic review is to assess the efficacy of Er-xian decoction (EXD), a formula of Chinese medicine, in relieving menopausal symptoms. Seven databases were extensively retrieved. The Chinese electronic databases include VIP Information, CBMdisc, and CNKI. The English electronic databases include AMED, CINAHL, Cochrane Library, and MEDLINE. Randomized controlled trials using EXD as a main intervention were included in the study selection. The quality of studies was assessed by Jadad scale and the criteria referred in Cochrane reviewers' handbook. Two independent reviewers were responsible for data extraction and assessment. Discrepancies were rectified referring to the original articles. The efficacy of EXD treatment for menopausal symptoms was evaluated by meta-analysis. There were 154 articles retrieved according to the search strategy, 677 participants involved in the 5 studies that satisfied the selection criteria. Meta-analysis indicated that administration of EXD significantly relieved at least one menopausal symptom when compared to the control group at a 95% confidence interval (p<0.01). The curing effect of EXD with all symptoms relieved was significant as compared with the control groups (p<0.01). The results also indicated that the efficacy of EXD was better than the other non-menopausal hormone therapy (p<0.01), while there was no significant difference between the EXD and menopausal hormone therapy groups. The EXD is effective in treating menopausal symptoms. However, owing to the low quality of the investigated studies, more randomized controlled trials are needed before evidence-based recommendation regarding the effectiveness of EXD in the management of menopausal symptoms can be provided.

Hematidrosis (bloody sweat): a review of the recent literature (1996-2016).

Hematidrosis is an eccrine sweat disorder characterized by one or more episodes of spontaneous, bloody sweating from non-traumatized skin. The author carried out a systematic review of all cases of hematidrosis reported in PubMed over the past 20 years. A total of 25 cases were reviewed; 21 were women (84%), the median age was 13 years (range 9-72), and the majority (62%) were from Asia, mainly India. Hematidrosis was located on the face-including the forehead (40%), eyes (40%), and ears (36%)-in 96% of the cases and on the umbilicus in 24% and the palms in 20%. Prodromal symptoms were reported by almost 30% of the patients. Possible triggering factors were identified in 56% of the cases; most of these (86%) were stress factors within families (conflicts or abuse) or at school. In two cases, platelet dysfunction and epilepsy were suspected as culprits. Nine patients had a psychiatric diagnosis associated with hematidrosis. The outcome was favorable in most of the cases with medical treatment (e.g., beta-blocker, anxiolytics) and psychological support. The number of cases has increased in recent years. Hematidrosis appears to be a somatization disorder that mainly affects children from developing countries. Its physiopathology remains largely unknown. It deserves better recognition because it is usually a temporary condition when managed properly.

Pseudochromhidrosis: report and review of literature.

Chromhidrosis is a rare condition where colored sweat comes from the apocrine or eccrine glands. Pseudochromhidrosis is an uncommon condition where colored sweat is related to specific dye-producing bacteria, drugs, dyes, or chemical agents. This article provides a literature review of the various etiology, investigation, treatment, and prognosis. We propose an investigative algorithm to assist dermatologists, pediatric dermatologists, and general practitioners to diagnose this uncommon condition. The treatment options rely on the primary etiology such as removing dyes and chemical agents first and then treating the chromogenic bacteria. Topical and oral erythromycin seems to be the most effective treatment both in unidentified and identified chromogenic bacteria cases. Results and prognosis were excellent and without recurrence.
