Meridian Tropism and Compatibility of Chinese Medicine from Theory of Brain Sweat Pore / 中国实验方剂学杂志

Since LIU Hejian proposed the concept of sweat pore， the theory of sweat pore has experienced accelerated development. Especially with the advances in modern human anatomy and physiology， the microscopic anatomy of sweat pore begins to focus on the intercellular space， ion channels and other membranous space with channels， pores， doors， etc.， which exert the functions of exchanging fluid， information， and energy inside and outside blood vessels and discharging metabolic wastes so as to maintain the normal operation of organs. Therefore， sweat pore is the structural basis for the movement of Qi and the central link of Qi-fluid exchange in the body. The brain， as the house of original spirit， is in charge of the spirit of five Zang-organs. The brain sweat pore is pivotal for the circulation of Qi， blood， and fluid in the brain， and it is the structural basis for the normal physiological functions of the brain. The dysfunction of the brain sweat pore will cause the stagnation of Qi and the abnormal transport of blood and fluid. It will cause the abnormal exchange of Qi， liquid and other material and information， which fail to nourish the original spirt and cause the loss of vital activity， eventually leading to consciousness and emotion disorders. The treatment should focus on opening the brain sweat pore， smoothing the exchange of Qi and fluid inside and outside the pore， and restoring the Qi movement， so as to cure encephalopathy. At present， western medicine treatment of encephalopathy needs to solve the problem of drug efflux from the blood-brain barrier and improve the effective concentration of drugs into the brain. The structure and function of brain sweat pore is similar to those of the blood-brain barrier. The aromatic resuscitative medicines and wind-extinguishing medicines can open the brain sweat pore. When being combined with other medicines， they can lead the medicine to enter the brain to restore the Qi movement of the brain sweat pore and enhance the therapeutic effect. Liver-pacifying wind-extinguishing medicines， insect medicines， tonifying medicines， heat-clearing toxin-removing medicines， and damp-draining medicines can treat pathological factors such as wind， phlegm， stasis， deficiency， toxin， and dampness， respectively. These medicines， combined with the medicines with the tropism to brain meridians， can open the brain sweat pore and guide the medicine into the brain to enhance the effective concentration of the medicine， thereby enhancing the efficacy against encephalopathy.

Discussion on Coronary Microcirculation Disorder after Myocardial Ischemia Reperfusion Based on “Collaterals-Sweat Pore Qi and Fluid” Theory / 中医杂志

Coronary microcirculation disorder after myocardial ischemia reperfusion （MIR） is a prominent problem in the treatment of coronary heart disease. According to the physiological commonality between “collaterals-sweat pore qi and fluid” and coronary microcirculation， and the evolution of the course of MIR， it is believed that “heart collateral stasis obstruction， sweat pore constraint and block” is the cause of coronary microcirculation disorder. The evolution of the pathogenesis can be divided into three periods. During the myocardial ischemia period， the pathogenesis is heart collaterals obstruction and sweat pores empty， while during the ischemia reperfusion period， it is internal formulation of deficiency wind， spasms of collaterals or slight heart collaterals obstruction； in the coronary microcirculation disorder period， sweat pores constraint and block， constraint transforming into heat， qi and fluid failing to diffuse are the pathogenesis. The corresponding treatment principle is assisting dredge with supplementation， and supplementing deficiency to dispel stasis； treating wind and blood simultaneously， and extinguishing wind to arrest convulsion； clearing heat and cooling blood， and diffusing qi and unblocking qi and fluid. Moreover， it is recommended to treat the heart and lungs simultaneously， and regulate the heart and liver at the same time.

Rare CFTR large deletions: a series of cases / Grandes deleções raras no CFTR: uma série de casos

Aims: this paper aims to describe diagnosis and follow-up of patients affected by the Cystic Fibrosis (CF) manifestations and CFTR large deletions. For this, we performed a retrospective analysis of medical records, including genotyping and retrospective follow-up of clinical and lung function data. Electronic and printed medical records of patients followed at a referral outpatient clinic in CF were evaluated. Case description: we found that three patients had large deletions in the CFTRgene, being two of them heterozygous (heterozygous with deletion on exons from 2 to 3, and heterozygous for deletions on exons from 25 to 27) and one of them homozygous (homozygous for the deletions on exons from 19 to 21). One patient had a false negative result in complete genetic sequencing. All three received standard treatment for CF. Two patients died from CF pulmonary complications. Therefore, false negatives findings in CFTR sequencing for the diagnosis of CF are rare but may be more frequent in patients with large deletions. Conclusions: CFTR large deletions are associated with severe CF phenotypes

Objetivo: este trabalho tem como objetivo descrever o diagnóstico e o acompanhamento de pacientes acometidos pelas manifestações da fibrose cística e grandes deleções do gene CFTR. Para isso, realizamos análise retrospectiva de prontuários, incluindo genotipagem e acompanhamento retrospectivo de dados clínicos e de função pulmonar. Descrição dos casos: foram avaliados prontuários eletrônicos e impressos de pacientes acompanhados em ambulatório de referência em fibrose cística. Encontramos três pacientes com grandes deleções no gene CFTR, sendo dois deles heterozigotos (heterozigotos com deleção nos éxons de 2 a 3 e heterozigotos para deleções nos éxons de 25 a 27) e um deles homozigoto (homozigoto para as deleções nos éxons de 19 a 21,). Um paciente apresentou resultado falso negativo no sequenciamento genético completo. Todos os três receberam tratamento padrão para fibrose cística. Dois pacientes morreram de complicações pulmonares da fibrose cística. Portanto, achados falsos negativos no sequenciamento CFTR para o diagnóstico de fibrose cística são raros, mas podem ser mais frequentes em pacientes com grandes deleções. Conclusão: grandes deleções de CFTR estão associadas a fenótipos graves de FC

Sweat biosensors for sports monitoring / Biossensores de suor para monitoramento esportivo / Biosensores de sudor para la monitorización deportiva

ABSTRACT Introduction: Biometric sweat monitoring is an important tool for optimizing sports training. The possibility of developing a wearable amperometric lactate biosensor using a screen-printed carbon electrode (SPCE) impregnated by Ag nanoparticles (Ag NPs) for sweat determination in sports monitoring is questioned. Objective: To develop a sensor with GCE substrate coated on Ag NPs/SPCE. Methods: FESEM and XRD analysis were used for the morphological and structural characterizations of Ag and SPCE NPs, respectively. Results: FESEM, EDS, and XRD revealed that Ag NPs were uniformly dispersed in SPCE. The electrochemical biosensor responded linearly to lactate in phosphate buffer solutions, with detection and sensitivity limits of 1.2 µM and 14.2 mAcm-2 mM-1, respectively. Conclusion: The results suggest that Ag NPs/SPCE can be used to continuously monitor lactate levels in sweat as a practical and reliable biosensor for use. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Nevus apocrino puro: una entidad raramente sospechada / Pure apocrine nevus: a rarely suspected entity

Los nevus apocrinos puros son hamartomas de las unidades pilosebáceas caracterizadas por proliferaciones benignas de glándulas apocrinas maduras, la cual es una descripción microscópica realizada en los reportes de patología sin que se nombre el diagnóstico exacto. Considerando además, los diagnósticos diferenciales clínicos y la baja frecuencia de este diagnóstico, presentamos un caso clínico y una revisión del tema

Pure apocrine nevi are hamartomas of the pilosebaceous units characterized by benign proliferations of mature apocrine glands, which is a microscopic description made in pathology reports without the exact diagnosis being named. Considering the clinical differential diagnoses and its low frequency, we present a case report and a review of the literature on this topic

Clinical complications in children with false-negative results in cystic fibrosis newborn screening

Abstract Objective: To present signs and symptoms and clinical course in cystic fibrosis patients with false-negative newborn screening (CF NBS). Materials and methods: All children presented in this paper were covered by CF NBS. The group of 1.869.246 newborns was screened in the Institute of Mother and Child in Warsaw within a period of 01.01.1999 - 31.05.2019. Screening protocols evolved over time from IRT/IRTto IRT/DNA/EGA. Results: The authors identified 11 patients with false-negative NBS, in whom CF was diagnosed based on clinical symptoms or the examination of siblings with positive CF NBS. In the study group, the diagnosis was made significantly later in comparison to positive CF NBS patients ranging from 2 months to 15 years of age. CF NBS strategy does not significantly affect the sensitivity of the screening. Conclusion: In the presence of clinical symptoms, additional diagnostics must be implemented, in spite of the negative screening results. At first, the sweat test should be conducted, followed by a DNA analysis of the most common mutations in the given population. The diagnostic process requires searching for CFTR mutations not typically associated with a high chloride concentration in sweat. Repetition of sweat chloride concentration enables the diagnosis in children whose initial chloride values in sweat are borderline, and no CF-causing mutations are detected. In strong clinical indications, the extension of DNA analysis (EGA) is recommended in order to identify rare CF variants. In children with meconium ileus, genetic analysis is mandatory.

Ayurvedic Approach and Updates Related to Sveda and Svedavaha Srotasa

Knowledge of Ayurveda is based on specific fundamental principles. Dosha, Dhatu, Mala, Srotasa are some among them. Malas are the waste products which primarily generate after digestion of food. While Srotasa are the channels or pathways in the human body which carries Dosha, Dhatu, Mala and Mana. Sveda (sweat) is one of the waste product which forms after digestion of food or in the process of metabolism of adipose tissue. Formation, transportation and elimination of Sveda is carried out by Sveadavaha Srotasa and it helps to regulate body temperature, maintain skin moisture and excrete toxic substance from body. Detail description of concept Sveda, Svedavaha Srotasa, its normal mechanism, importance in manifestation of various diseases and its application in treatment is described in Ayurvedic texts. Thinking of this fact, for better acknowledgment of these concepts and its role in the practice this comprehensive review has been done.

Mutational Spectrum of the CFTR Gene in the Kazakhstan Population

Objective: To study the frequency and spectrum of CFTR gene variants in different ethnic groups of Kazakhstan. Methods: We reviewed the records of 58 patients with cystic fibrosis. All the patients underwent molecular genetic analysis to reveal genotype-phenotype correlations. Results: The median (IQR) age of the patients was 5.4 year (7 months, 18 year); 40% were diagnosed at the age of 5-10 year. The study identified 28 specific variants: p.Phe508del, the variant most common in the European population, was detected in 30 patients (51.7%). Variants other than p.Phe508del were revealed in 31% (21 patients). Conclusions: We found a number of specific variants characteristic of the Kazakhstani population. A pronounced regression of disease symptoms was detected in patients with mild mutations; whereas in patients with severe mutations, therapy produced very little effect.

Clinicopathological features of clear cell hidradenoma in 23 cases / 中国基层医药

Objective:To investigate the clinicopathological features, immunophenotype and differential diagnosis of clear cell hidradenoma, and to analyze the origin of clear cell hidradenoma and the underlying mechanism.Methods:The clinical data of 23 cases of clear cell hidradenoma who underwent surgical resection in Suzhou Municipal Hospital between December 2017 and July 2021 were retrospectively analyzed. Clinical manifestation, imaging features, pathological features and prognosis of the 23 cases of clear cell hidradenoma were analyzed. Expression levels of epithelial membrane antigen, cytokeratin 20, cytokeratin 7, cytokeratin 14, carcinoembryonic antigen, and gross cystic disease fluid protein 15 were detected by immunohistochemical staining technique using the EnVision system. Periodic acid-Schiff (PAS) staining was performed to visualize glycogen.Results:Among the 23 cases, 8 were male and 14 were female, aged 14-94 years, with a median age of 55 years. The first symptom of clear cell hidradenoma was epidermal bulgels in 18 cases.Contrast ultrasonography showed a subcutaneous cystic solid echo mass with abundant blood flow in the solid part. The tumor histologically consisted of two types of cells: secretory epithelial cells or glandular epithelial cells and clear cells. Twenty cases had tumors with the features of benign clear cell hidradenoma. Two cases had atypical clear cell hidradenoma with atypia and mitosis. One case had malignant clear cell hidradenoma. Tumor cells were positive for epithelial membrane antigen, cytokeratin 7, cytokeratin 14, carcinoembryonic antigen, and gross cystic disease fluid protein 15 and they were Periodic acid-Schiff-positive. Twenty-three patients were followed up for 2-36 months, of which 4 were lost to follow-up and the rest had no recurrence of clear cell hidradenoma.Conclusion:Clear cell hidradenoma is rare and has a good prognosis. Malignant clear cell hidradenoma is rarer and has a poor prognosis. Diagnosis of clear cell hidradenoma is mainly based on comprehensive analysis of pathological features and immunophenotypes. Clear cell hidradenoma should be differentiated from metastatic clear cell carcinoma, spiral adenoma, cortical adenoma, and malignant melanoma.

Comparison of sweating components during endurance exercise under the same load in a hot environment and in a neutral thermal environment / 体力科学

Sweat contains electrolytes (minerals), therefore, it is necessary to consider its loss through sweat in the fluid replacement strategy in sports. The purpose of this study was to compare the concentration of components in sweat, such as electrolytes (minerals), when endurance exercise is performed in hot and neutral thermal environments. Eight men cycled for 60 min at 55% VO2peak under two envitonment conditions: a hot environment (WetBulb Globe Temperature (WBGT): 29.0±0.2℃; Heat) and a neutral thermal environment (WBGT: 20.5±0.2℃; Con). During exercise, sweat loss, core temperature, and heart rate (HR) were measured, and sweat from the chest, back, and thigh was collected. The core temperature, sweat loss, and HR increased significantly in Heat. The sweat electrolyte concentration was significantly higher in Heat than in Con only for Na. Regarding the amount of electrolyte loss from sweat, Na and K showed a significantly higher value than Con in Heat in comparison of each region, and the total loss amount of three regions in Cu also had a significantly higher value than Con in Heat. In addition, there was no difference in the concentration of Ca and Cu between the regions, but there was a significant difference in the amount of loss. It was concluded that even if there was no difference in the electrolyte concentration in sweat, the amount of electrolyte loss increased in K and Cu in a hot environment, and that there was a site difference in the amount of loss in Ca and Cu.

Hidradenoma papilífero de la vulva con componente de carcinoma in situ: reporte de caso y revisión de la bibliografía / Papilliferous hidradenoma of the vulva with carcinoma in situ component: case report and literature review

Resumen ANTECEDENTES: El cáncer de vulva es relativamente raro, representa menos del 1% de los tumores malignos de la mujer; su incidencia aumenta con la edad. La variedad más frecuente es el carcinoma escamoso (80 al 90%), seguido del melanoma. En este reporte se revisa un carcinoma de origen glandular, como el hidradenoma papilífero del tipo glándula mamaria (mammary-like) de la vulva. CASO CLÍNICO: Paciente de 50 años, con una lesión papular en la vulva de dos años de evolución, con crecimiento lento y progresivo, ocasional sensación de masa y dolor, con colposcopia negativa, sin antecedentes de patología mamaria y con una biopsia previa que reportó hidradenoma papilífero vulvar. Se trató con resección completa de la lesión, con anestesia regional, con bordes libres, no se identificó algún componente infiltrante. En la actualidad permanece sin evidencia de recaída ni requerimiento de tratamientos adicionales durante el seguimiento. CONCLUSIÓN: El hidradenoma papilífero es una lesión benigna, poco frecuente, relacionada con las glándulas anogenitales de tipo mammary-like, con buen pronóstico. El tratamiento recomendado es la escisión quirúrgica, que casi siempre es curativa.

Abstract BACKGROUND: Vulvar cancer is relatively rare, representing less than 1% of malignant tumors in women; its incidence increases with age. The most frequent variety is squamous cell carcinoma (80 to 90%), followed by melanoma. In this report we review a carcinoma of glandular origin, such as papilliferous hydradenoma of the vulva of the mammary gland (mammary-like) type. CLINICAL CASE: We present a 50-year-old patient with 2 years evolution of a papular lesion on the vulva with slow and progressive growth, intermitent sensation of mass and pain, with negative colposcopy, no history of breast pathology and with a previous biopsy that reported vulvar papilliferous hydradenoma. She was treated with complete resection of the lesion under regional anesthesia, with free margins, without identifying an infiltrating component and currently without evidence of relapse or requirement of additional treatments. CONCLUSION: Papilliferous hidradenoma is a rare benign lesion related to the mammary-like anogenital glands, with a good prognosis and its recommended treatment is surgical excision, which is generally curative.

Benign glandular schwannoma

ABSTRACT We report a case of a benign glandular schwannoma in a 63-year-old male who presented with a solitary subcutaneous mass on the left knee, with no previous history of neurofibromatosis type 1. This histological subtype is rare, with only 38 cases reported in the literature. Some of the glands found in this patient resembled sweat glands. These lining stromal spindle cells were positive for S-100 but negative for EMA. S100 was faintly staining the glandular elements. All the glands in the tumor were positive for EMA, particularly at the luminal borders. They were also positive for pancytokeratin. The cystic areas variably show intraluminal, foamy, and hemosiderin-laden macrophages. The different glands expressed two patterns. Some of these were reactive for CK7 and low molecular weight keratin. Immunohistochemical workup is mandatory to assess the neoplastic nature of this glandular component.

Foxa1 mediates eccrine sweat gland development through transcriptional regulation of Na-K-ATPase expression

Eccrine sweat glands (ESGs) perform critical functions in temperature regulation in humans. Foxa1 plays an important role in ESG maturation and sweat secretion. Its molecular mechanism, however, remains unknown. This study investigated the expression of Foxa1 and Na-K-ATPase (NKA) in rat footpads at different development stages using immunofluorescence staining, qRT-PCR, and immunoblotting. Also, bioinformatics analysis and Foxa1 overexpression and silencing were employed to evaluate Foxa1 regulation of NKA. The results demonstrated that Foxa1 was consistently expressed during the late stages of ESGs and had a significant role in secretory coil maturation during sweat secretion. Furthermore, the mRNA abundance and protein expression of NKA had similar accumulation trends to those of Foxa1, confirming their underlying connections. Bioinformatics analysis revealed that Foxa1 may interact with these two proteins via binding to conserved motifs in their promoter regions. Foxa1 gain-of-function and loss-of-function experiments in Foxa1-modified cells demonstrated that the activities of NKA were dependent on the presence of Foxa1. Collectively, these data provided evidence that Foxa1 may influence ESG development through transcriptional regulation of NKA expression.

Dermatite néonatale: à propos de 116 cas recueillis dans un CHU d'Abidjan / Newborns dermatitis: about 116 cases collected in a university hospital in Abidjan

Objectifs : Déterminer le profil épidémiologique des dermatoses du nouveau-né et de décrire les différents aspects cliniques des dermatoses néonatales observées. Matériel et méthodes : L'étude s'est déroulée au Centre hospitalier universitaire de Cocody (Abidjan). L'étude était transversale, à visée descriptive et analytique, réalisée sur la base d'un recrutement prospectif. Ont été inclus, les nouveau-nés ayant été vus en consultation externe ou en hospitalisationdu 4 avril 2018 au 23 août 2018 chez qui le médecin pédiatre avait observé des lésions cutanées et/ou muqueuses.Ensuite,le diagnostic était posé par le dermatologue référant de l'étude. Résultats : Pendant la période d'étude, 116 nouveau-nés ont été recensés. La moyenne d'âge était 16,86 ± 8,4 jours avec un âge médian de 19 jours. Lesex ratio (H/F) était de 1. Dans plus de la moitié (53,5%) des cas, les lésions évoluaient depuis moins de 5 jours. Une dermatose transitoire était diagnostiquée dans plus de la moitié des cas (51,7%) et dans près du tiers des cas (32,6%) une dermatose infectieuse. Les dermatoses transitoires du nouveau-né étaient dominées par la miliaire sudorale (40%), l'érythème toxique (23%), la desquamation néonatale (10,7%) et l'hyperplasie néonatale (10,7%). Les taches mongoloïdes représentaient3,3% des cas. Les dermatoses infectieuses étaient essentiellement représentées par des infections mycosiques (68,4%) et bactériennes (31,6%). Les autres dermatoses néonatales observées étaient dominées par dermite du siège (64,3%) et les nævi congénitaux (21,5%). Plus de la moitié (57,1%) des cas d'érythème toxique néonatal survenaient entre le 6e et le 10e jour de vie. L'âge moyen des patients présentant une dermatose transitoire était de 14,31 jours contre 19,41 jours pour ceux présentant les autres dermatoses. La différence observée au niveau de l'âge était statistiquement significative (p < 0,05). Conclusion: Les dermatoses néonatales sont multiples et variées. Certaines sont transitoires, ne nécessitant pas toujours de prise en charge thérapeutique. Leur diagnostic n'est pas toujours évident pour le pédiatre d'où la nécessité d'une étroite collaboration entre pédiatres et dermatologues afin d'améliorer la démarche diagnostique et parfois thérapeutique

Aims: To determine the epidemiological profile of newborn dermatitis and to describe the different clinical aspects of the observed neonatal dermatitis. Procedure: The study took place at the University Hospital of Cocody (Abidjan). The study was cross-sectional, descriptive and analytical, carried out on the basis of prospective recruitment. The study included newborns who were seen in outpatient or inpatient settings by 4 april 2018 to 23 August 2018 and in whom the pediatrician had observed cutaneous and/or mucosal lesions. The diagnosis was made with the collaboration of a dermatologist. Results: During the study period, 116 newborns were identified. The age of the patients seen in pediatrics with dermatitis varied from 1 to 28 days, with a mean of 16.86 ± 8.4 days. The median age was 19 days. The most representative age range (32.8%) was 24-28 days. The sex ratio (M/F) was 1. In almost 2/3 of the cases, the children were born at term, 29.3% were premature and 5.2% were born after term. In almost 2/3 of the cases (63.8%), the newborns had a birth weight of more than 2500 g. Only 3.4% of newborns seen in pediatric consultations were referred for a dermatitis. The age of the lesions at the time of consultation varied from 1 to 26 days, with a mean of 06.19 days ± 5.13. In more than half (53.5%) of the cases, the lesions had evolved for less than 5 days. Transient dermatitis was more frequent (51.7%), followed by infectious dermatitis (32.8%). Transient dermatitis of the newborn was dominated by sweaty miliaria (40%). Infectious dermatitis were mainly represented by mycotic (68.4%) and bacterial (31.9%) infections. Bacterial dermatitis were composed of neonatal impetigo (83.3%) and folliculitis (16.7%). In almost half of the cases (46.1%) the mycotic dermatitis were represented by candidosis intertrigo and in 38.5% of the cases there was oral candidiasis. The other neonatal dermatitis observed were dominated by diaper rash (64.3%) (Photo 2) and congenital nevi (21.5%). More than half (57.1%) of the cases of toxic erythema neonatorum occurred between days 6 and 10 of life. Nearly half (41.6%) of the cases of sudoral miliaria occurred between birth and day 5 of life. More than half (57.1%) of the cases of sebaceous hyperplasia occurred before the 5th day of life. All cases of neonatal scaling and mongoloid spots were already present between birth and day 5 of life. The mean age of patients with transient dermatitis was 14.31 days compared with 19.41 days for those with the other dermatitis. The difference in age was statistically significant (p < 0.05). The transient dermatitis predominated in male neonates while the other dermatitis predominated in females, however the difference observed at the level of sex was not statistically significant (p > 0.05). Conclusion: The diagnosis of neonatal dermatitis is not always obvious, especially on black skin where few publications have been published

Malignant adnexal cutaneous tumor of the scalp: a case report of difficult differential diagnosis between metastatic breast cancer and primary sweat gland tumor / Neoplasia maligna de glândula anexial cutânea em couro cabeludo: um caso de dúvida diagnóstica entre carcinoma metastático de mama e tumor primário de glândula sudoríparas

This paper describes a case of a 71-year-old female who initially went to a dermatologist to assess a scalp skin tumor, which performed an incisional biopsy. Anatomopathological and immunohistochemical study revealed a preliminary diagnosis of breast carcinoma metastasis. Although the patient had no medical history of breast cancer, due to this result, she was referred to a mastologist, who investigated her breast nodules for the possible primary focus of the carcinoma. Despite an active investigation through imaging tests, biopsies, and mammotomy, without finding any possible primary focus on the breasts. Finally, the lesion on the scalp was entirely removed by a plastic surgeon. New anatomopathological and immunohistochemical exams confirmed the diagnosis of breast carcinoma metastasis. Given these results, the authors discuss the difficulty in diagnosing differentiation from a primary or metastatic neoplasm of the scalp, with the resources currently available, until the conclusion that it was a primary carcinoma of the sweat gland.

Este artigo descreve o caso de uma mulher de 71 anos que inicialmente foi ao dermatologista para avaliação de tumor de pele no couro cabeludo, e que realizou biópsia incisional desta lesão. O estudo anatomopatológico e imuno-histoquímico revelou um diagnóstico preliminar de metástase de carcinoma de mama. Embora a paciente não tivesse história clínica de câncer de mama, devido a esse resultado, foi encaminhada à mastologista, que investigou seus nódulos mamários para localizar o possível foco primário do carcinoma. Apesar de uma investigação ativa por meio de exames de imagem, biópsias e mamotomia, não foi encontrado nenhum possível foco primário nas mamas. Por fim, a lesão no couro cabeludo também foi totalmente removida por um cirurgião plástico. Novos exames anatomopatológicos e imuno-histoquímicos confirmaram o diagnóstico de metástase de carcinoma de mama. Diante desses resultados, os autores discutem a dificuldade em diagnosticar a diferenciação de uma neoplasia primária ou metastática do couro cabeludo, com os recursos disponíveis atualmente, até a conclusão de que se tratava de um carcinoma primário da glândula sudorípara.

Intertrigo-like hand-foot syndrome unaffecting the site of surgery for axillary osmidrosis: the first case reported worldwide / 中华皮肤科杂志

A 25-year-old female patient presented with recurrent painful erythema and blisters on the palms and soles as well as in the axillary and inguinal regions for 1 month. Seven years ago, the patient underwent a small-incision sweat gland resection in the bilateral axillae for the treatment of axillary osmidrosis. One month ago, she underwent chemotherapy with pegylated liposomal doxorubicin (PLD) after surgery for stage-ⅡB cervical synovial sarcoma. During the 3 sessions of chemotherapy, she developed painful edematous erythema on the palms, soles, axillae and groins, which gradually worsened along with the increase in the number of chemotherapy sessions. Skin examination showed large areas of edematous erythema with clear boundaries at bilateral palms, soles, and intertriginous sites including axillae and groins, with millet- to soybean-sized blisters and erosions on the surface; the skin lesions showed relatively high temperature and positive Nikolsky's sign with obvious tenderness; there was no skin lesions or tenderness at the site of small-incision surgery for axillary osmidrosis in bilateral axillae. Histopathological examination of the axillary skin lesions showed formation of blisters under the basal layer and necrosis of some sweat glands. The diagnosis of PLD-associated intertrigo-like hand-foot syndrome was confirmed. The history of surgery for axillary osmidrosis and normal skin at the surgical site in this case suggest that the pathogenesis of this disease may be related to toxic skin reactions to the drug excreted through sweat glands.

A Case of Sweating Disorder Successfully Treated by Keishikaogito Based Prescription / 日本東洋医学雑誌

There are multiple options for treating hyperhidrosis, including Kampo medicine. However, as for acquired idiopathic generalized anhidrosis, steroid therapy is the only way to treat the patients. There are few clinical reports including Kampo treatment for anhidrosis. We report a case in which keishikaogito based prescriptions were effective in treating symptoms caused by decreased sweating. A 69-­year-­old woman visited our institute in June 201X, complaining of reduced sweating and abnormal feelings about body temperature. Her physician prescribed various sorts of Kampo medicines, but no improvement had been shown. We considered that she was not able to sweat and had water accumulation under her skin. She was given Keishikaogito based prescrip­tions, and she came to sweat spontaneously and abnormal feeling about body temperature improved. Honzo-biyo says “Astragalus promotes sweating if there is no sweating, stops it if there is sweating.” Keisetsu Otsuka said in Kinki-yoryaku-kowa that Astragalus works in both cases with too much and too little water. Kampo treatment especially containing Astragalus can be effective for sweating disorders.

A influência da idade e do genótipo sobre os níveis de cloreto do suor em uma população pediátrica com fibrose cística no estado da Bahia / The influence of age and genotype on sweat chloride levels in a pediatric population with cystic fibrosis in the state of Bahia

Introdução: a fibrose cística é a doença autossômica recessiva mais comum em populações caucasianas e a sua etiologia está associada a variantes patogênicas no gene CFTR. O teste do suor é considerado o padrão ouro para o diagnóstico dessa enfermidade. Estudos apontam que o genótipo do CFTR e a idade dos indivíduos influenciam as concentrações de cloreto no suor. Objetivos: pesquisar a correlação entre os níveis de cloreto no teste do suor e a idade ao diagnóstico de indivíduos com fibrose cística e comparar as concentrações iônicas do cloreto entre os sexos, diferentes faixas etárias e três grupos diversos de genótipos do CFTR. Metodologia: realizou-se um estudo de corte transversal, incluindo sujeitos de 0 a 20 anos, com diagnóstico confirmado de fibrose cística. Os indivíduos selecionados foram agrupados de acordo com as variáveis analisadas. Calcularam-se os valores descritivos das concentrações de íons cloreto de cada grupo. Utilizou-se o teste de Spearman para a análise da correlação entre a idade ao diagnóstico e os níveis de cloreto no suor. Resultados: 64 indivíduos foram incluídos no estudo, sendo 51,56% do sexo masculino. A mediana (Min ­ Max) da idade ao diagnóstico foi de 7 meses (1-206). Não foi observa da correlação entre a idade dos indivíduos ao diagnóstico e os níveis de cloreto no suor. As concentrações medianas de cloreto foram maiores nos escolares (106 mEq/l), no sexo feminino (102 mEq/l) e nos heterozigotos F508del/Classe I a III (108 mEq/l); e menores nos adolescentes (100 mEq/l) e nos heterozigotos F508del/Classes IV a VI (77 mEq/l). Conclusão: os níveis de cloreto no suor não apresentaram correlação com a idade dos indivíduos ao diagnóstico. A variação considerável dos níveis iônicos entre os grupos de diferentes genótipos corrobora que o teste do suor é um bom preditor da avaliação funcional do canal CFTR.

Introduction: cystic fibrosis is the most common autosomal recessive disorder in Caucasian populations and its etiology is associated with pathogenic variants in the CFTR gene. The sweat test is considered the gold standard for the diagnosis of the disease. Some studies suggest that CFTR genotype and age affect sweat chloride concentrations. Objectives: to investigate the correlation between sweat chloride levels and age at diagnosis of individuals with cystic fibrosis and to compare ionic chloride concentrations among sexes, different age groups and three distinct groups of CFTR genotypes. Methodology: a cross-sectional study was conducted, which included CF subjects from 0 to 20 years of age. The selected individuals were clustered on the variables in analysis. The description values for chloride ion concentrations in each group were calculated. The Spearman's test was used to analyze the correlation between the age at diagnosis and sweat chloride levels. Results: 64 individuals were included, 51,56% male. The median (Min ­ Max) age at diagnosis was 7 months (1-206). There was no correlation between the age at diagnosis and sweat chloride levels. The median of the chloride concentrations were higher for schoolchildren (106 mEq/l), females (102 mEq/l) and heterozygous F508del/Classes I to III (108 mEq/l), and reached the lowest values for teenagers (100 mEq/l) and heterozygous F508del/Classes IV to VI (77 mEq/l). Conclusion: sweat chloride levels did not correlate with the age of individuals at diagnosis. The substantial variation of ionic levels among groups of distinct genotypes corroborates that the sweat test is a good predictor for functional assessment of the CFTR channel.

A rare case of hematohidrosis in a patient with paranoid schizophrenia

Hematohidrosis is a very rare yet fascinating clinical entity in which blood is excreted in sweat under extreme physical or emotional stress. The causes can be attributed to variety of etiological factors such as systemic disorders, vicarious menstruation, excessive exertion, and psychogenic and idiopathic causes. Although the episodes are usually self-limiting and do not affect the health status of the patient, the very phenomenon can be quite scary for the patient and family members. Amongst the psychogenic causes, various mental illnesses can result in Hematohidrosis, but it is more commonly reported so far with anxiety spectrum illnesses and depression. The distinctive feature of the case presented by authors is its association with Hematohidrosis and its symptoms of Paranoid Schizophrenia. Objective of this study the association between symptomatology of Paranoid Schizophrenia and its effect on Hematohidrosis After due consent from the patient, relatives and permission from the ethics committee of the institution, clinical history was obtained from the patient interviews. The case was followed longitudinally on each follow up. Appropriate blood investigations were done. Information obtained was compiled to form a case report. The improvement in psychotic symptoms corresponded with reduced frequency of bleeding episodes. As anti-psychotic treatment was initiated, patient started showing improvement in psychotic symptoms. This co-incided with the reduced severity and frequency of Hematohidrosis. Improvement in anxiety associated with psychotic symptoms was most probably responsible for improvement in symptoms of Hematohidrosis.
