Normative data for aquagenic wrinkling of palms in children 1-15 years of age: A cross-sectional study

BACKGROUND

Aquagenic wrinkling of palms (AWP) is emerging as a screening test for cystic fibrosis (CF). There is lack of normative data for the same in our population.

OBJECTIVES

To generate normative data for AWP in children 1-15 years of age and to describe the factors associated with it.

METHODS

Children aged 1-15 years were enrolled after obtaining informed consent and assent of the parent and child based on age. Information regarding age, gender, anthropometry, indications for visiting hospital and drug intake were noted down. Wrinkling test was done using distilled water maintained in room temperature. Sweat chloride analysis was done using Nano duct sweat analysis system for children having AWP within 3 min. The mean/median time to wrinkle was noted and presented as centile curves after smoothing.

RESULTS

The mean (SD) and median (interquartile range [IQR]) aquagenic wrinkling time in children 1-15 years of age was 4.88 (1.066) and 5 (4-5.75) minutes respectively. The mean (SD) and median (IQR) time for AWP was 4.78 (1.076) and 5 (4-5) minutes respectively for boys and 4.98 (1.048) and 5 (4-6) minutes, respectively for girls. The time taken to wrinkle was observed to increase with age. Males have earlier AWP than females. There was no association between AWP and anthropometry or sweat chloride levels.

CONCLUSION

We have estimated the normative data for AWP in children 1-15 years of age which can be used for CF screening in children with typical clinical features from resource limited settings.

Aquagenic wrinkling of the palms: review of the literature

Aquagenic wrinkling of the palms (AWP) is a rare dermatological disease characterized by development of rapid and excessive wrinkling and oedema of the palms and transient whitish or yellowish papules without erythema on the palmar surfaces after immersion in water. This phenomenon can be accompanied by pain and/or pruritus. The most common treatment of AWP involves aluminium-based topicals. This article discusses the associations, pathological mechanisms and treatment options of AWP.

The effectiveness of botulinum toxin type A (BTX-A) in the treatment of facial skin oily seborrhea, enlarged pores, and symptom complex of post-acne

BACKGROUND

This study aimed to examine the effectiveness of botulinum toxin type A (BTX-A) in the treatment of acne.

METHODS

The study was conducted in 2018 on 12 patients, 10 females and two males, aged 35 years on average. The injections with BTX-A were given during 2 weeks into the face skin in a dosage of 0.125-0.250 units.

RESULTS

Skin moisture indexes increased during the therapy by 4% (P ≤ 0.05), and porosity decreased by 7% (P ≤ 0.01). Maximal changes were recorded for the sulci and pigmentation of the skin, namely, its values decreased by 10 and 9%, respectively (P ≤ 0.01). BTX-A is recommended for an application not only in plastic surgeries but also for local correction of acne on the patient's skin.

CONCLUSION

A positive correlation was revealed between the duration of treatment and reduction of skin oiliness (0.87), pigmentation (0.78), skin sulci (0.84), and skin porosity (0.88), and negative correlation was established with increased skin moisture (-0.64). The obtained dependencies apply for the therapy period of up to 2 weeks. Pharmacological properties of BTX-A allow recommending it as a drug used in post-acne therapy.

Aquagenic wrinkling of the palms after brief immersion to water test as a screening tool for cystic fibrosis diagnosis

BACKGROUND

Aquagenic wrinkling of the palms (AWP) is an excessive and early palmar wrinkling occurring after Brief Immersion to Water (BIW), and has been reported as a frequent finding among cystic fibrosis (CF) patients.

OBJECTIVES

To evaluate and assess the diagnostic performance of BIW test as an initial screening tool for CF diagnosis.

METHODS

We measured AWP in CF patients, CF-heterozygotes (CF-het) and normal controls. The AWP parameters of palmar wrinkling, oedema, papules, pruritus and pain were assessed at 3, 7 and 11 min after a BIW test was performed for all the participants. Statistical analyses explored the progression of AWP in time for the three groups and assessed the diagnostic performance of BIW test as a diagnostic screening tool for CF.

RESULTS

A total of 250 individuals (100 CF patients, their 50 CF-het parents, 100 healthy controls) were included in the analysis. The average age in years (mean ± SD) was 10.4 ± 4.0 for CF, 35.9 ± 6.1 for CF-het and 10.5 ± 4.0 for controls. The rate of positives for AWP at 3 min among CF patients, CF-het and controls was 68%, 8% and 0%, respectively (P < 0.01). Kaplan-Meier analysis showed a clear trend towards earlier appearance of all five parameters in the direction controls < hetCF < CF (P values <0.01). The best diagnostic performance in detecting between CF patients and non-CF was achieved by the presence of papules and wrinkling at 7 min (sensitivity/specificity: 94.0%/98.3% and 100.0%/92.0%, respectively).

CONCLUSIONS

A strong association between AWP and CF was detected. AWP after BIW could be elicited easily and possibly can be used as an initial screening tool to assess if an individual with symptoms and signs that raise the likelihood of CF is a CF patient.

Aquagenic (pseudo) keratoderma (aquagenic palmoplantar keratoderma, aquagenic wrinkling of palms)

Aquagenic palmoplantar keratoderma (APK) is an uncommon hereditary or sporadic condition that is characterized by edematous flat-topped papules appearing on palmar skin with wrinkling after brief water exposure. APK has been associated with cystic fibrosis (CF), presenting with the same mutations found in CF (usually ΔF508 of the CFTR gene), either homozygous or heterozygous. APK may be idiopathic or drug-induced. The diagnosis is easily made if one is aware of this entity. Topical aluminum hydroxide and botulinum toxin injections are the most commonly used treatments. The sporadic form may have a shorter course compared with the hereditary one, resolving spontaneously after a few years. The condition should no longer be considered a true keratoderma but rather a pseudo keratoderma, and in spite of the many different names found in the literature, the term "aquagenic (pseudo) keratoderma" seems to be the most appropriate one.

Treatment of hereditary palmoplantar keratoderma: a review by analysis of the literature

BACKGROUND

No specific or curative therapy exists for hereditary palmoplantar keratoderma (hPPK), which can profoundly alter patient quality of life, leading sometimes to severe functional impairment and pain. The rarity and the aetiological diversity of this group of disorders can explain the difficulty in comparing the efficacy of available treatments.

OBJECTIVES

To review the different treatments tried in patients with hPPK since 2008, their efficacy and safety, with an evaluation of the various therapeutic modalities that can be used to treat hPPK.

METHODS

We undertook a comprehensive review of the literature data published since 2008.

RESULTS

Only a few case series and individual case reports were identified. Topical (emollients, keratolytics, retinoids, steroids) and systemic treatments (mostly different retinoids), often combined, are used to relieve symptoms. Oral retinoids appear to be the most efficient treatment, but not in all PPK forms, and with variable tolerance. New targeted treatments, according to the specific mechanisms of hPPK, appear promising for the future.

CONCLUSIONS

More studies using robust methodology and involving larger cohorts of well-characterized patients (phenotype-genotype) are necessary and should be prioritized by structured networks, such as the European Network for Rare Skin Diseases (ERN-Skin), with the aim of better management of patients with rare skin diseases.

Dermatosis inducida por el agua: queratodermia acuagénica, a propósito de un caso

La queratodermia acuagénica es una entidad benigna, caracterizada por producir pápulas blanquecinas o traslúcidas pocos segundos después del contacto con el agua.Se presenta el caso de una paciente de 16 años de edad con aparición de múltiples pápulas confluentes y asintomáticas en ambas palmas al contacto con el agua, que desaparecían luego del secado. En el estudio de histopatología se observó dilatación de los conductos ecrinos y cambios en el estrato córneo.Esta rara condición de etiología desconocida se ha relacionado con disfunción neuronal, alteraciones de las glándulas ecrinas y, más recientemente, con alteraciones en las acuaporinas. Se puede diagnosticar con una prueba semiológica sencilla llamada ‘la mano en el balde’; la sospecha clínica es fundamental para hacer el diagnóstico, ya que los hallazgos histopatológicos pueden ser sutiles e inespecíficos. El tratamiento tópico incluye mecanismos de barrera y la toxina botulínica.

Difficulties Coding Dermatological Disorders Using the ICD-10: The DIADERM Study

BACKGROUND AND OBJECTIVES

The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) has some shortcomings when it comes to coding certain dermatological disorders. To overcome these shortcomings, a compatible version of the ICD-10 specifically adapted to dermatology was produced in Spain in 1999. The recent DIADERM study recorded 10 999 dermatological diagnoses using a representative sample of dermatologists working at outpatient clinics in Spain. The aims of the current study were to identify diagnoses from the DIADERM study that could not be coded using the adapted ICD-10, determine why, and check if they could be coded using the draft ICD-11.

MATERIAL AND METHODS

We included all dermatological diagnoses from the DIADERM study that could not be assigned a code from the adapted ICD-10. We then quantified and recorded all the diagnoses that could not be coded using either the adapted ICD-10 or the draft ICD-11.

RESULTS

Of the 10 999 diagnoses analyzed, 41 had not been assigned a code. Of these, 19 were assigned an adapted ICD-10 code on reassessment. However, the adapted ICD-10 and the draft ICD-11 lacked specific codes for 22 and 17 diagnoses, respectively.

CONCLUSIONS

The adapted ICD-10 can be used to correctly code the vast majority of dermatological diagnoses seen in routine clinical practice. Nevertheless, the system does have some minor shortcomings when it comes to coding certain diseases, particularly newly discovered and emerging diseases. Some of these problems, however, were resolved with the new ICD-11. Based on our findings, we propose some modifications to the ICD-11.

Botulinum Toxin Off-Label Use in Dermatology: A Review

BACKGROUND

Botulinum toxin is a neurotoxin produced by the bacterium Clostridium botulinum which causes a flaccid muscle paralysis. It is currently used for aesthetic treatments and in the focal hyperhidrosis. Recently, botulinum toxin has also been used experimentally in many other dermatological conditions with good results.

OBJECTIVE

To review and analyze the possible botulinum toxin off-label applications published.

METHODS

A retrospective review of the published data was conducted.

CONCLUSIONS

this potent drug can lead to several off-label indications of interest for dermatologists. Further clinical trials are still needed to better understand the real efficacy and safety of these applications and to standardize injection and dose protocols.

Sporadic and familial cases of aquagenic keratoderma

BACKGROUND

Aquagenic keratoderma is a dermatosis characterized by transient whitish and transluscent hyperwrinkling after water exposure. The aim of the current report was to present a sporadic and familial cases of aquagenic keratoderma.

OBSERVATION

Sporadic Case: A 38-year-old female patient presented with eruption in the right hand after exposure to water. The patient was placed on systemic acitretin therapy with the diagnosis of idiopathic acquired aquagenic keratoderma. No recurrence occurred during a 6-month follow-up period. Familial Cases: A 55-year-old male patient, who was engaged in fishery, presented to the outpatient clinics of the department of dermatology due to whitish vesicles in the palms of both hands. It was realized that the father, sister, and brother of the patient had similar complaints. The cases were thought to have familial aquagenic keratoderma; however acitretin therapy could not be initiated due to elevated alanine aminotransferase and triglyceride levels. Topical application of salicylic acid 10% and 10% urea containing lotions was effective but did not prevent recurrence.

CONCLUSION

Systemic acitretin may be an effective agent in the treatment of aquagenic keratoderma, and topical application of 10% salicylic acid and 10% urea-containing lotion did not prevent recurrence.

Watersport hands

Aquagenic syringeal acrokeratoderma is a newly described condition of the palms and soles characterized by hypopigmented papules and plaques, elicited after submersion in water. Symptoms include a burning pain and a tightening sensation in the palms, as well as hyperhidrosis. Initially thought to be rare, its frequent citation in the literature points to a more common entity. It is more often found in young women and has been linked to a number of medications and illnesses, including nonsteroidal anti-inflammatory drugs and cystic fibrosis. It is typically self-limiting, but certain medications such as topical aluminum chloride or salicylic acid ointment have been found to be an effective treatment option. This case details a collegiate-level coxswain who presented to the university athletic training room with a typical presentation of aquagenic syringeal acrokeratoderma. For an aquatic athlete, aquagenic syringeal acrokeratoderma can be a distressing condition that can limit training and athletic participation. As such, the sports medicine physician should be knowledgeable about aquagenic syringeal acrokeratoderma to provide effective counseling and treatment options for the athlete.

Aquagenic keratoderma. Two new case reports and a new hypothesis

Aquagenic keratoderma has been described as a transient condition affecting predominantly young females and defined clinically by the appearance of palmar hyper-wrinkling accentuated after immersion in water. We present two new cases with aquagenic palmoplantar acrokeratoderma - a child and a young male. A significant clinical improvement was achieved after topical treatment with aluminum salts. Aquagenic palmar keratoderma may be a clue to cystic fibrosis in adolescents and young adults. We developed a new hypothesis on its pathogenesis.

Cutaneous irritancy of water

Abstract Water is an ubiquitous irritant that exerts its irritancy through different mechanisms. Water passage and optimal water content is a highly controlled process of human skin and changes in the water gradient may lead to skin diseases. The pH, osmolarity, and temperature of water can all be attributes of water irritancy. In addition, the irritancy of water is also determined by individual susceptibility.

High prevalence of aquagenic wrinkling of the palms in patients with cystic fibrosis and association with measurable increases in transepidermal water loss

Aquagenic wrinkling of the palms (AWP) is a cutaneous phenomenon marked by the transient formation of edematous, translucent papules and plaques on the palms and fingertips within minutes of water exposure. AWP is anecdotally reported in patients with cystic fibrosis (CF) and several studies have recently confirmed this association. The primary aim of this study was to determine the prevalence of aquagenic wrinkling of the palms in subjects with cystic fibrosis (CF) compared to controls, and secondarily to evaluate for genotype-phenotype correlations among CF subjects found to have AWP. Fifty-one children with CF and 25 control children who were being treated for asthma underwent a 5-minute hand immersion in lukewarm water. The test for AWP was positive if subjects demonstrated >30% wrinkling over the palm. Secondary analyses explored associations with genotype, pancreatic and pulmonary function, body mass index (BMI), and sweat chloride levels. Palmar transepidermal water loss (TEWL) was also measured for all subjects with and without AWP. Forty-three of the subjects (84%) with CF demonstrated aquagenic wrinkling, in contrast to none (0%) of the controls. These results remained statistically significant when stratified for by age and race. TEWL was significantly higher in CF subjects with AWP compared to CF subjects without AWP and controls. No genotype-phenotype correlations were detected in patients with AWP, nor were there associations of AWP with other phenotypic features of CF, although these analyses were likely underpowered. Aquagenic wrinkling of the palms is prevalent in children with CF and is associated with increased TEWL.

Aquagenic wrinkling of the palms and the potential role for genetic testing

Aquagenic wrinkling of the palms (AWP) is a condition characterized by excessive wrinkling, palmar edema, and whitish papules accompanied by pain, pruritus, or discomfort after brief immersion of the hands in water. It is well documented to be associated with cystic fibrosis (CF), with several theories regarding the pathogenesis having been proposed. We report a case of two sisters with AWP in whom CF has not been diagnosed and review the literature on AWP and its association with CF and CF carrier status. Because diagnosis of mild forms CF or knowledge of an underlying CF genetic mutation is frequently unknown, identification of AWP may represent the only sign of such mutations. The dermatologist plays an integral role in early detection of AWP, and the importance of genetic testing in such patients cannot be overlooked. We recommend various measures to apply in clinical practice to ensure diagnosis and decrease morbidity and mortality in patients.

Unilateral aquagenic keratoderma treated with botulinum toxin A

BACKGROUND

Aquagenic keratoderma is a rare transient disease that occurs after water immersion and disappears shortly after drying. Most cases involve the palms and fingers bilaterally but it can also affect the soles. Few cases have been associated with drugs but its pathogenesis remains unclear.

MAIN OBSERVATION

We report a 60-year-old man with a 30-year-history of aquagenic keratoderma of the right palm without associated hyperhidrosis or history of drug intake. After unsuccessful treatment with 15% aluminium chloride hexahydrate gel, botulinum toxin A injections led to significant improvement within 2 weeks.

CONCLUSIONS

To our knowledge, this case is the first report of idiopathic unilateral aquagenic keratoderma in the medical literature. It is the third report of successful treatment with botulinum toxin A which is in favor of a role of sweat glands in the pathogenesis of aquagenic keratoderma.

Localized aquadynia responsive to clonidine in a 13-year-old girl

A 13-year-old girl sought medical care for pain in both palms that consistently occurred after brief exposure to water and resolved spontaneously 20 to 30 minutes after immersion. The pain was not associated with wrinkling of the palms. After excluding other causes of acrodynia and water-induced discomfort, we diagnosed the patient as having idiopathic localized aquadynia. Treatment with systemic clonidine led to a substantial improvement in her symptoms. To our knowledge, this patient represents the only fifth reported case of aquadynia and the first child affected by this enigmatic condition.

Is acquired symmetrical acrokeratoderma a new dermatosis? Two case reports and Chinese literature review

BACKGROUND

A series of cases characterized by symmetrical acral hyperkeratosis, mainly involving the dorsal surface of the hands, feet, and wrists, but sparing the palmoplantar areas, as well as rapid immersion upon exposure to water have been recently described in China, but similar disorders have not been reported in the English literature.

METHODS

The clinicopathologic features of two cases of acquired symmetrical acrokeratoderma were reported and 27 Chinese patients were reviewed.

RESULTS

The disorder typically occurred in young or middle aged men. Brown to black hyperkeratotic patches were symmetrically distributed particularly on the wrists and dorsum of hands, fingers, and feet, but without involvement of palms and soles. The lesions became whitish with mild swelling immediately after contact with water and improved generally in winter. Histopathologic examination revealed epidermal hyperkeratosis, acanthosis, and papillomatous hyperplasia, as well as superficial perivascular lymphohistiocytic infiltrate. Main ultrastructural features of the immersed lesion were epidermal hyperkeratosis and spongiosis with partial split of the desmosomes.

CONCLUSION

This disorder may be a new dermatosis, and the term "acquired symmetrical acrokeratoderma" could exactly reflect its clinicopathologic characteristics.
