Hair-to-Hair Trichoscopy: An Objective Method to Assess Effectiveness of Botulinum Toxin in a Clinical Trial for Androgenetic Alopecia

Introduction

Androgenetic alopecia (AGA) is the most common alopecia affecting both genders leading to a potential decrease in quality of life and self-esteem. A current concern in trichology is how to accurately measure clinical response in both daily medical practice and academic research. Hair-to-hair (H2H)-matching technology™ has recently emerged as a technique to evaluate variations in follicular units, hair shaft number, and thickness. This study aimed to describe the methodology employed in a clinical trial using this technology to test the efficacy of botulinum toxin (BT) for male AGA.

Methods

This pilot study is a triple-blind, randomized, split scalp, placebo-controlled clinical trial. Patients enrolled were submitted to injections half of the scalp with 50 IU of BT and the other half with 1 mL of normal saline as a control. The trial involved three visits (weeks 0, 12, and 24) and 8 global clinical photographs followed by H2H-matching trichoscopy were captured before the injections at each visit. Paired t test analysis was employed for matched pairs of the following parameters: total hair count, the total number of terminal hair strands, average shaft thickness, and the number of hairs lost or gained during each visit. Then, the software compared the differences between the two sides (BT vs. placebo) per scalp zone and a long time.

Conclusion

The combination of manually corrected image processing, follicular map, and H2H-matching technology™ appears to be the most precise way to evaluate changes in hair count and thickness over time. The design is reproducible and can help other researchers and dermatologists in their clinical practice to obtain reliable results in similar scientific research.

Normal Trichoscopic Findings after Hair Transplantation in Androgenetic Alopecia: A Prospective Case Series

Background

Trichoscopy can be very useful for evaluation for hair transplantation (HT), helping rule out simulators of androgenetic alopecia (AGA). There are only a few reports about normal trichoscopic findings after HT.

Objective

The aim of this study was to evaluate donor and recipient area trichoscopy after FUE in HT without complications in AGA patients.

Method

A prospective study was carried out with 10 patients, for 24 weeks, with photographic follow-up, using FotoFinder®. Patients were evaluated from week 1 (w1) to week 8 weekly, then, at week 12 and week 24 post-HT.

Results

Main results were perifollicular crusts, donor area erythema, recipient area erythema, perifollicular erythema, white circles, perifollicular whitish halos, repilation black dots, dystrophic hairs, folliculitis, yellow dots. We discussed the meaning of each of these findings in the period in which they occurred.

Conclusion

Normal trichoscopic findings in post-transplant patients have not been well established yet. Our findings are an attempt to define a normal pattern. Future studies with a longer follow-up may be necessary to corroborate these results.

Fracture in Irradiated Rat Femur: A Description of an Experimental Model and Evaluation of its Effectiveness

Objective  We aim to describe an experimental model for studying femoral fractures in rats after exposure to ionizing radiation, demonstrating a way to apply a substance for analysis, the method for patterning fracture and irradiation, and how to evaluate its effectiveness based on radiographic studies. Methods  We used 24 rats divided into 2 groups of 12 animals each. The STUDY group was exposed to ionizing radiation and treated with saline solution, and the CONTROL group was not exposed to radiation and was treated with saline solution. All animals were subjected to standardized fracture of the right femur that was fixed with intramedullary wire. The efficiency of the bone union was assessed by radiographic exam. Results  Fracture healing was more efficient in bones not exposed to ionizing radiation ( p  = 0.012). All fractures met the criteria of being simple, diaphyseal, transverse or short oblique. Conclusion  The experimental model presented is an efficient alternative for the study of fractures in irradiated bones in rats.

Dermal Thickness Increase and Aesthetic Improvement with Hybrid Product Combining Hyaluronic Acid and Calcium Hydroxyapatite: A Clinical and Sonographic Analysis

Hyaluronic acid filler injections are regarded as the gold standard procedure for facial rejuvenation. Standing as the second most injected cosmetic filler, calcium hydroxyapatite-based fillers are also widely used worldwide. However, to our knowledge, prospective studies assessing patient satisfaction and sonographic changes in dermal thickness after a single session of a hybrid filler combining hyaluronic acid and calcium hydroxyapatite have not been previously published.

Methods

This was a single-center, prospective, quasi-experimental study comprising 15 participants between 32 and 63 years of age. Each participant received a single-session treatment based on facial subcutaneous injections of HArmonyCa, a hybrid combination filler comprising hyaluronic acid and calcium hydroxyapatite. This study involved an intrapatient control design and a 120-day follow-up with clinical and sonographic assessment. For this purpose, standardized photographic images, high-frequency ultrasound evaluations, and physician- and patient-oriented overall aesthetic improvement scores were recorded at 0, 30, 90, and 120 following the procedure.

Results

According to our findings, 20% of the subjects had an exceptional improvement; 20%, "very improved"; and 60%, "improved." Intrapatient sonographic comparison showed a significant increase in dermal thickness, at 90 and 120 days, only on the side treated (P < 0.001).

Conclusion

In our clinical study, a single-session treatment with a hybrid product combining hyaluronic acid and calcium hydroxyapatite resulted in positive cosmetic satisfaction and increased dermal thickness.

Efficacy and Safety of Scalp Microneedling in Male Pattern Hair Loss

Introduction

There are few reports involving scalp microneedling in MPHL patients, and in most of them, physical stimulus is associated with other therapeutic agents. The aim of this study was to evaluate the efficacy and risks of isolated scalp microneedling in MPHL patients.

Methods

Thirty patients were included in this randomized single-blinded study and submitted to 4 monthly scalp microneedling sessions. Two different microneedling devices were used: roller (n = 15) and tattoo cartridge (n = 15). Scalp coverage and hair density changes were measured 4 and 16 weeks after the last session. Adverse events were observed throughout the study, and scalp biopsies were performed before and after to investigate scarring changes.

Results

Four of 12 participants in the roller group and 2 of 14 participants in the tattoo cartridge group showed an improvement in clinical pictures at the first follow-up visit. Only half of these patients sustained an improvement until the last follow-up visit. No benefit in hair density was observed in either group. No reports of adverse events were made. Neocollagenesis and elastolysis were noted in scalp biopsies.

Discussion/Conclusion

Isolated scalp microneedling did not show improvement in scalp coverage or hair density of MPHL participants in this study.

[COVID-19 and breast cancer screening in Brazil: a comparative analysis of the pre-pandemic and pandemic periods]

The scope of this study was to evaluate the impacts of COVID-19 on breast cancer screening in Brazil. Data were collected from the Ambulatory Information System relating to "bilateral screening mammography" from January/2015 to December/2021. Analyses were performed by region and for Brazil. The average of exams in each month of the year was calculated based on 2015-2019 data, which was compared, monthly, with the number of exams in 2020 and 2021, obtaining the gross and percentage difference between these values. The same analysis was performed for the total number of exams in 2020 and 2021, individually, and for the two years combined. In 2020 there were reductions in the number of exams, which ranged from 25% (North) to 48% (Northeast), resulting in 1.749 million fewer exams than expected in the country (a drop of 44%). In 2021, the Midwest region presented a number of exams 11% higher than expected, while the other regions presented drops between 17% (North) and 27% (Southeast/South), resulting in 927 thousand exams fewer than expected in Brazil (reduction of 23%). In the joint analysis (2020/2021), reductions varied by region from 11% (Midwest) to 35% (Southeast/South), culminating in 2.676 million exams fewer than expected in Brazil (reduction of 33%).

Bicalutamide and the new perspectives for female pattern hair loss treatment: What dermatologists should know

Female pattern hair loss (FPHL) is the most common form of alopecia in women. FPHL may compromise body image and strongly affect self-esteem, negatively impacting quality of life. Currently, the only Food and Drug Administration (FDA) approved drug for its treatment is topical minoxidil, with a variable response rate. Recently, a few studies in FPHL have pointed out bicalutamide as an emergent selective androgen receptor antagonist with a favorable safety and tolerability profile. This review aimed to summarize and discuss the key information on this new therapy for FPHL. Bicalutamide has no diuretic effect. It does not cross the blood-brain barrier, and it has little effect on serum luteinizing hormone. Additionally, bicalutamide was found to be effective on women presenting with other features of hyperandrogenism such as seborrhea, acne, and hirsutism with mild and well-tolerated adverse effects. Despite the high prevalence and psychosocial impairment, FPHL treatment remains challenging. Therefore, although future prospective, comparative, randomized clinical trials are essential to establish the ideal dose and efficacy of the drug, oral bicalutamide appears to be a promising option to expand the arsenal of FPHL treatment.

Effect of therapeutic regimens and polypharmacy on health-related quality of life of people with multiple myeloma: a cross-sectional study in Belo Horizonte, Brazil

OBJECTIVE

Multiple myeloma (MM) is an incurable hematological cancer and its treatment is geared to promote better Health-Related Quality of Life (HRQoL). We aimed to assess HRQoL and compare scores between variables on therapeutic regimens and polypharmacy in MM patients.

METHODS

This cross-sectional study was performed from April/2019 to February/2020 in Belo Horizonte, Brazil. HRQoL scores were obtained by the QLQ-C30 and QLQ-MY20 instruments. Data were retrieved from interviews and medical records. Therapeutic regimens were grouped into thalidomide-containing regimens; bortezomib-containing regimens; bortezomib and thalidomide-containing regimens; other therapeutic regimens, and remission group. We performed univariate analyses by the Mann-Whitney method and adopted the Kruskal-Wallis test for multiple comparisons. Robust multiple linear regression was used to determine the association between independent variables and the HRQoL scores.

RESULTS

The sample included 225 participants and most patients (65.3%) were on active treatment and had worse scores concerning future perspective. Polypharmacy was associated with worse scores on all scales in the univariate analyses. We observed a difference in the global health and body image (p < .05) scales in the multiple comparisons with therapeutic regimens. The global health scale difference was found between groups with other regimens and the remission group (p < .05). The difference between the bortezomib and thalidomide-containing regimens and remission group was not statistically significant (p = .077) in the body image scale. The multiple linear regression maintained the association of polypharmacy with worse HRQoL scores.

CONCLUSION

We identified an independent association between HRQoL and polypharmacy in MM patients. However, there was no difference between the evaluated regimens, suggesting they are equivalent in Brazil about HRQoL.

Burden of syphilis in Brazil and federated units, 1990-2016: estimates from the Global Burden of Disease Study 2019

Background:

Syphilis is a chronic infectious disease that has created challenging situations for humanity for centuries. Transmission can occur sexually or vertically, with great repercussions on populations, particularly among women and children. The present study presents information on the main burden imposed by syphilis generated by the Global Burden of Disease (GBD) Study 2019 for Brazil and its 27 federated units.

Methods:

We described the metrics of incidence, deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs), standardized by age and per 100,000 inhabitants, from 1990 to 2019, and we compared the disease burden between the years 1990 and 2019.

Results:

In Brazil, the disease burden increased between 2005 and 2019 for all metrics. Although a higher incidence of syphilis was found among women in 2019, DALYs [YLLs (males: 15.9%; females: 21.8%), YLDs (males: 25.0%; females: 50.0%), and DALYs (males: 16.2%; females: 22.4%)] were higher among men. In 2019, the highest DALY rate per 100,000 inhabitants was observed in individuals aged above 50 years. The State of Maranhão presented the highest values of DALYs {1990: 165.2 [95% uncertainty interval (UI) 96.2-264.4]; 2005: 43.8 [95% UI 30.3-62.4]; 2019: 29.1 [95% UI 19.8-41.1]} per 100,000 inhabitants in the three years analyzed.

Conclusions:

The burden of syphilis has increased in recent years. Men presented higher DALYs, although the incidence of the disease was higher in women. Syphilis affects a large number of people across all age groups, causing different degrees of disability and premature death (DALYs).

Epidemiological, Clinical, Trichoscopic, and Histopathological Features of Lupus Erythematous Mimicking Alopecia Areata: A Multicenter Retrospective Study

Introduction

All types of lupus erythematosus (LE) may cause hair loss. Nonscarring alopecia was correlated with systemic LE, based on its high specificity. Discoid LE can also appear as nonscarring patches in early stages. Patchy alopecia LE-specific may also mimic alopecia areata (AA) - which can co-occur with LE. The distinction is fundamental to early diagnosis and effective treatment. This study aims to analyze clinical, epidemiological, trichoscopic, and histopathological features of patients with patchy LE-specific alopecia, nonscarring type, mimicking AA.

Methods

This is a multicentric retrospective study. We reviewed the medical records of patients with a confirmed diagnosis of LE mimicking AA.

Results

Ten patients were included (90% female) with a mean age of 45.9 years. Clinically, 60% showed erythema and 70% presented incomplete hair loss. The most common trichoscopic findings were interfollicular arborizing vessels (90%) and scattered brown discoloration (80%). On histopathology, perivascular inflammation (85.7%), peribulbar lymphocytes (85.7%), and dermal pigment incontinence (71.4%) were present in most cases.

Discussion/Conclusion

Trichoscopy was found as an essential first step for the patchy alopecia diagnosis, enabling to differentiate LE from AA. Putting it mildly, trichoscopy raises the suspicion that leads to a biopsy, increasing the diagnostic accuracy with better outcome for patients.

Efeito colateral da pandemia de Covid-19 no Brasil sobre o número de procedimentos diagnósticos e de tratamento da sífilis

A sífilis, uma infecção vertical e sexualmente transmissível, curável e prevenível, é um problema de saúde pública no Brasil. Métodos diagnósticos e tratamentos são importantes no controle da doença. A pandemia de Covid-19 causou atrasos em diagnósticos e no tratamento na atenção primária em várias doenças e em diversos países, pois interrompeu padrões usuais de atendimento à saúde. O objetivo do estudo é identificar se houve menor número de procedimentos diagnósticos e de tratamento realizados para sífilis nos primeiros sete meses de 2020, comparativamente à média dos mesmos meses entre 2016 e 2019, no Brasil e nas unidades federativas. A redução no número de procedimentos seria um indicativo de atraso no diagnóstico, na detecção e no tratamento da sífilis em 2020. Foram utilizadas informações disponibilizadas no Sistema de Informações Ambulatoriais (SIA/SUS). Os achados para o Brasil indicaram queda de 1/3 nos procedimentos de diagnóstico e de tratamento referentes à sífilis nos sete primeiros meses do ano da pandemia, comparados com a média dos sete primeiros meses nos quatro anos anteriores (2016-2019). Indicadores mostram diferenças importantes por unidades da federação, apontando para maiores quedas proporcionais nos volumes de procedimentos no Norte e Nordeste, com ênfase nos estados do Maranhão, Roraima, Pará, Bahia, Rio Grande do Norte, Amazonas, Pernambuco e Amapá.

Efficacy of Minoxidil Combined With Photobiomodulation for the Treatment of Male Androgenetic Alopecia. A Double-Blind Half-Head Controlled Trial

BACKGROUND

Androgenetic alopecia (AGA) is a hair loss disorder that frequently affects the male population. Conventional treatment modalities are limited to minoxidil, 5α reductase inhibitors, and hair transplantation procedures. The efficacy of low-level laser therapy (LLLT), also known as photobiomodulation, in the treatment of AGA has been reported, yet little is known about the outcomes of combining photobiomodulation with other conventional therapies.

OBJECTIVE

To evaluate hair growth improvement in males with AGA, during the administration of minoxidil with and without photobiomodulation, using a half-head model.

STUDY DESIGN/MATERIALS AND METHODS

Twenty-one men with AGA agreed to undergo 12 minutes of low-level laser irradiation (using a modified Capellux®), followed by topical minoxidil application (1 ml of 5% solution), to the affected scalp two times per day for 6 months. The photobiomodulation devices were modified such that the left half emitted light, and the right half did not. Efficacy was assessed by blinded analyses of clinical photos and automated phototrichograms (Trichoscan®) taken before treatment and after 3 and 6 months of therapy.

RESULTS

None of the study participants experienced any adverse events. All patients showed improvements in hair coverage on both sides of the scalp at 3 and 6 months. On the side with combined treatments, the number of total hairs was significantly increased after 3 (P < 0.001) and 6 months (P = 0.001). A similar increase was also observed on the minoxidil-only side, at both 3 (P < 0.001) and 6 months (P < 0.001). No statistically significant differences were detected between sides (P > 0.05).

CONCLUSION

Additional improvement was not observed with the association of photobiomodulation to topical minoxidil in male AGA. Differences from previous studies that might have influenced our result include non-collimated light source, higher dosimetry, and a cohort with darker skin phototype and more severe alopecia.

Azithromycin for chronic eosinophilic rhinosinusitis with nasal polyp: a placebo-controlled trial

BACKGROUND

Chronic eosinophilic rhinosinusitis with nasal polyps (CRSwNP eosinophilic) is characterised by the formation of benign and bilateral nasal polyps. We aimed to compare the effectiveness of azithromycin as an immunomodulator with the use of a placebo in patients presenting with CRSwNP concomitant with asthma and aspirin intolerance after 3 months of treatment and at a 1-year follow-up.

METHODOLOGY

We performed a randomised, double-blind, placebo-controlled trial. Patients received 500 mg azithromycin orally three times/week for 12 weeks. Improvement was evaluated by staging, the Sino-Nasal Outcome Test (SNOT-22), and nasal polyp biopsy. Data collected at pretreatment and 3 months posttreatment were compared. Quality of life was evaluated at the 1-year follow-up.

RESULTS

Twenty-seven and 21 patients were treated with azithromycin and a placebo, respectively. The medication was well tolerated overall. Twenty patients (74%) in the azithromycin group and three patients (14%) in the placebo group were not refer- red for surgery at the end of the 3-month treatment. Regarding subjective improvement, there was a median decrease only in the azithromycin group, and the between-group difference was significant. SNOT-22 improvement was maintained in the azithromy- cin group at the 1-year follow-up.

CONCLUSIONS

Azithromycin could be considered a therapeutic option for patients presenting with CRSwNP concomitant with asthma and aspirin intolerance.

Índice de Vulnerabilidade Clínico-Funcional-20: proposta de classificação e hierarquização entre os idosos identificados como frágeis

Objetivo: O objetivo deste estudo foi identificar quais os idosos em risco de vulnerabilidade clínico-funcional que devem ser encaminhados para a atenção geriátrica-gerontológica especializada, tendo por base o Índice de Vulnerabilidade Clínico- Funcional-20 (IVCF-20) comparado com os escores da utilização da avaliação geriátrica ampla, utilizado como padrão ouro. Método: O estudo foi transversal, no qual foram comparados os resultados obtidos no IVCF-20 com os resultados verificados na Avaliação Geriátrica Ampla (AGA). Tendo em vista que idosos com escores acima de 6 estão em risco de vulnerabilidade clínico-funcional, objetivou-se definir, entre estes, a partir de qual escore os idosos seriam considerados em alto risco de vulnerabilidade, com base em alta especificidade (igual ou superior a 95%) e sensibilidade não inferior a 50%. Resultados: Identificou-se um ponto de corte de 15 pontos, com sensibilidade de 52% e especificidade de 98%. Conclusão: A elevada especificidade obtida indica que, provavelmente, poucos idosos em risco com pontuação igual ou superior a 15 seriam encaminhados desnecessariamente para a atenção gerontológica especializada, otimizando assim o uso dos recursos em saúde.

Relationship of the Pelvic-Trochanteric Index with greater trochanteric pain syndrome

OBJECTIVES

This study aimed to correlate a higher Pelvic-Trochanteric Index (PTI) with an increased varus of the femoral neck with greater trochanteric pain syndrome (GTPS). The secondary objective was to check whether the pelvic width changes with age.

METHODS

A prospective study was conducted to compare female patients diagnosed with GTPS (case group) with asymptomatic female participants (control group) from March 2011 to June 2017. On an anteroposterior pelvic radiograph, lines were drawn by two radiologists, and the PTI (ratio of the distance between the greater trochanters and distance between the iliac crests) was defined and the femoral neck-shaft angle was measured.

RESULTS

Data collected based on radiographs of 182 female patients (cases) and 150 female participants (controls) showed that the mean PTI was 1.09 (SD=0.01) in the case group and 1.07 (SD=0.01) in the control group (p<0.05), regardless of age. The distance between iliac crests increased with age (p<0.05) in symptomatic and asymptomatic individuals. It was also found that the mean femoral neck-shaft angle was 130.6° (SD=0.59) and progression of the varus angulation occurred with age in both groups, with a significance level of 5%.

CONCLUSIONS

The PTI was higher in patients with GTPS. The femoral neck-shaft angle does not differ between individuals with and without GTPS; however, it does decrease with age. The pelvic width tends to increase with aging in symptomatic or asymptomatic individuals; therefore, the increase in the pelvic width and decrease in the femoral neck-shaft angle can be interpreted as normal in aging women, which could alter the biomechanics of the hips and pelvis.

RISK FACTORS FOR POST-LIVER TRANSPLANT BILIARY COMPLICATIONS IN THE ABSENCE OF ARTERIAL COMPLICATIONS

BACKGROUND

- Biliary complications (BC) represent the most frequent complication after liver transplantation, up to 34% of cases.

AIM

To identify modifiable risk factors to biliary complications after liver transplantation, essential to decrease morbidity.

METHOD

Clinical data, anatomical characteristics of recipient and donors, and transplant operation features of 306 transplants with full arterial patency were collected to identify risk factors associated with BC.

RESULTS

BC occurred in 22.9% after 126 days (median) post-transplantation. In univariate analyses group 1 (without BC, n=236) and group 2 patients (with BC, n=70) did not differ on their general characteristics. BC were related to recipient age under 40y (p=0.029), CMV infection (p=0.021), biliary disease as transplant indication (p=0.018), lower pre-transplant INR (p=0.009), and bile duct diameter <3 mm (p=0.033). CMV infections occurred sooner in patients with postoperative biliary complications vs. control (p=0.07). In a multivariate analysis, only CMV infection, lower INR, and shorter bile duct diameter correlated with BC. Positive CMV antigenemia correlated with biliary complications, even when titers lied below the treatment threshold.

CONCLUSIONS

Biliary complications after liver transplantation correlated with low recipient INR before operation, bile duct diameter <3 mm, and positive antigenemia for CMV or disease manifestation. As the only modifiable risk factor, routine preemptive CMV inhibition is suggested to diminish biliary morbidity after liver transplant.

O Registro Civil nos quatro primeiros meses da pandemia de Covid-19 no Brasil: estudo comparativo entre óbitos por mês de ocorrência e de registro

O Registro Civil fornece informações aos estudos demográficos sobre mortalidade, fecundidade e nupcialidade. Questões têm surgido sobre o registro dos óbitos quando as causas de morte decorrem da Covid-19. A notificação pode acontecer com atraso. Com base nas informações disponibilizadas pelo Registro Civil de óbitos pela Covid-19, discriminados por dois grupos – data de registro e data de ocorrência –, o presente estudo compara estes grupos por categoria de município (capital, região metropolitana e interior), no período de março a junho de 2020, que corresponde aos quatro primeiros meses da pandemia no Brasil. Avaliam-se a magnitude e o sentido das diferenças de registros de óbitos entre os dois grupos. Foram utilizados gráficos e análise de regressão linear para comparações. Os achados indicam comportamento diferente de óbitos por mês de registro em comparação àqueles por mês de ocorrência entre março e junho.É importante identificar tal diferença de comportamentos dado que, para o monitoramento em curtíssimo prazo da pandemia, óbitos por data de registro antecipam óbitos cujo registro ainda será corretamente disponibilizado por data de ocorrência. Conclui-se que essa variação deve-se, principalmente, à correção e atualização sistemática das informações. Quanto à categoria de município, a maior diferença entre óbitos por mês de ocorrência e de registro foi observada para os municípios do interior, em consonância com o alastramento da epidemia rumo ao interior no mês de maio.  

novo coronavírus e a pneumonia

Objetivou-se analisar a evolução de internações e óbitos por pneumonia no Brasil e suas regiões no contexto da COVID-19. Trata-se de estudo observacional, retrospectivo, com dados secundários sobre o número de internações e óbitos por pneumonia, no primeiro trimestre de 2019 e 2020. Além das análises descritivas de números de internações e óbitos, foram calculadas e comparadas, mês a mês, as razões de chances (odds ratios) de ocorrência de internação e óbito em 2020, sendo 2019 a categoria de referência. As chances de morte por pneumonia foram maiores que as chances de internação por pneumonia em praticamente todo o país, a partir de março de 2020. Os achados indicam que foi no mês de março que a pandemia de COVID-19 chegou ao país e não apenas à Região Sudeste. Palavras-chave: Síndrome respiratória aguda grave; mortalidade; hospitalizações; COVID-19.

Estimativas de impacto da COVID-19 na mortalidade de idosos institucionalizados no Brasil

Resumo O presente estudo tem como objetivo estimar o impacto da COVID-19 na mortalidade de idosos institucionalizados no Brasil. Foram estimados números de óbitos pela doença para o País, Unidades da Federação e Regiões, com base nas estimativas calculadas e efetuadas neste trabalho do percentual de óbitos de idosos que ocorreriam em instituições de longa permanência de acordo com os totais. Essa estimativa foi baseada em informações disponíveis para uma série de países. O percentual ponderado foi de 44,7%. Estimaram-se 107.538 óbitos de idosos nestas instituições no Brasil em 2020, por COVID-19. São previstos maiores números de óbitos na Região Sudeste (48.779 óbitos), seguida da Região Nordeste (28.451 óbitos); São Paulo é a Unidade da Federação que na estimativa será mais afetada (24.500 óbitos). Fica claro o forte impacto da COVID-19 na população idosa residente em instituições de longa permanência para idosos. As estimativas ultrapassam para o país 100 mil idosos, potencialmente os mais frágeis e vulneráveis, e são baseadas em número de óbitos totais conservador, tendo em vista outras estimativas e a situação alarmante de crescimento dos números de óbitos no Brasil.

Use of vibrating anesthetic device reduces the pain of mesotherapy injections: A randomized split-scalp study

Pain evaluation during local injections is a complex process. Injections cause patient's distress, especially when the target is a sensitive area such as scalp. Nonpharmacological methods as vibration before and during the procedure have been used to reduce pain. Mesotherapy has become a popular nonsurgical procedure for nonscarring alopecia, such as androgenetic alopecia (AGA) and alopecia areata (AA). Vibration has been successfully used in dermatological procedures, pediatrics, and dentistry. No study was found on vibration anesthesia during scalp mesotherapy. To analyze the effect of a vibration anesthetic device (VAD) during scalp mesotherapy on the patients' comfort.This is a randomized split-scalp study; thirty patients received mesotherapy with or without VAD on half of their scalp. Numerical rating scale (NRS) was used to measure self-reported pain. To test difference in means and medians in comparing device use and by treatment (AGA or AA), Student's t tests and Wilcoxon signed rank tests were used. Overall mean pain score on the no vibration-assisted side was 8.0 ± 1.0 while pain score for the vibration side was 2.3 ± 1.5, for AGA (P < .001) and 7.4 ± 1.2 and 2.1 ± 1.3, respectively, for AA (P < .001). Findings were similar for medians. No complications were found following procedure. To the best of our knowledge, this is the first study analyzing the effect of VAD in patients undergoing scalp mesotherapy. The VAD technique was found to be safe, effective, simple, and suitable for scalp procedures.

Molecular tracking of pathogens in central venous catheter

BACKGROUND

Central venous catheter-related bloodstream infection is an important adverse event in health care. Molecular methods are not yet substitutive of microbiological in the detection of the pathogens responsible for the infection, but they can help in the epidemiological characterization.

AIM

To detect bacteria by polymerase chain reaction, from material extracted from the tip of central catheters of patients suspected of infection at the intensive care unit.

METHODS

Catheters (n = 34) of patients suspected of central venous catheter-related infection were analyzed by polymerase chain reaction. The findings were compared with culture of catheter tip and blood cultures performed by the hospital.

FINDINGS

The prevalence of bacteria was Staphylococcus aureus (50%), Enterococcus faecalis (41.2%), Klebsiella pneumoniae (32.4), Pseudomonas aeruginosa (20.6%), Acinetobacter baumannii (38.2%), Escherichia coli (2.9%), and Enterobacter cloacae (0%). No blood culture showed bacterial growth, the culture of catheter tip revealed bacteria in 21 (61.8%) and the polymerase chain reaction had positivity in 31 (91.2%) of the catheters. The mean central venous catheter time was 11 days, and the jugular vein was the site of insertion.

CONCLUSION

The molecular method identified more bacteria than microbiological methods and revealed colonization of the catheters. The most commonly found bacteria are in the environment and in the microbiota of the skin, which suggests contamination by the hands of health professionals and points out the need for more efforts in preventive strategies.

[Social integration profiles among non-frail elderly institutionalized individuals in Natal, State of Rio Grande do Norte, Brazil]

The scope of this study was to profile non-frail elderly individuals in Long-Stay Care Institutions in Natal, emphasizing social integration and stratification in philanthropic and private institutions in 2012. The instrument used was the Brazil Old Age Schedule (BOAS). Descriptive analysis was carried out and sociodemographic and health profiles of the elderly were estimated using the Grade of Membership (GoM) scale to obtain social integration typologies. The results indicated that 68 elderly were eligible; 63.2% were female, and 51.5% were 80 years or older; 43% reported poor or extremely poor health. The application of the GoM method yielded three profiles. The first is characterized by the elderly with higher presence of sociable/integrated men living in philanthropic institutions (22% of the elderly); the second mainly encompasses women in philanthropic institutions, with vulnerable health conditions and depression (34.9%); the third is the profile with higher levels of integration/sociability in private institutions, but also characterized by elderly persons with functional disability (34.9%). This study is important since integration and independence must be a part of social life of the elderly irrespective of the place where they live.

Análise de confiabilidade da causa básica e associadas de morte

Introdução: Realizou-se avaliação das informações sobre mortalidade por câncer no Hospital Luxemburgo (CACON), Belo Horizonte, em 2017. Métodos: Para avaliar confiabilidade da causa básica (CB) e o sub-registro de câncer por meio de causas múltiplas (CM) dados do Sistema de informações sobre mortalidade (SIM) foram investigados em prontuários e relacionados aos registros hospitalares de câncer (RHC). Resultados: Por capítulo, houve diferença significativa (p<0,001) nos óbitos por neoplasias (sub-registro) e doenças do aparelho circulatório, respiratório e digestivo (sobrerregistro). Por agrupamento, neoplasias dos órgãos digestivos respiratórios e genitais masculinos foram sub-registrados (p<0,001). A investigação reduziu causas pouco úteis de morte (91 óbitos) — principalmente neoplasias de localização mal definida (n=23) e pneumonias não especificadas (n=23). Análise de CM incrementou em 24% as menções de câncer. Conclusão: A metodologia adotada revelou-se efetiva e de baixo custo para que informações sobre mortalidade por câncer tenham cada vez mais qualidade.

A importância da gestão correta da condição crônica na Atenção Primária à Saúde para o enfrentamento da COVID-19 em Uberlândia, Minas Gerais

A pandemia pela COVID-19 trouxe a necessidade de novas estratégias para o seu enfrentamento pela atenção primária à saúde, uma vez que abordagens convencionais poderão não ser efetivas. A infecção pelo SARS-Cov-2 tem como principais alvos os idosos e os indivíduos com hipertensão arterial, diabetes mellitus e doença cardiovascular prévia. No município de Uberlândia-MG, este grupo populacional, elemento central da gestão da saúde, vem sendo estratificado por risco, conforme propõe modelo de atenção as condições crônicas. A estratificação de risco tem sido fundamental para o enfrentamento da crise da COVID-19, sendo planejada não apenas de acordo com a idade das pessoas idosas, e sim a partir do índice de vulnerabilidade clínico-funcional, aliando a isto a estratificação de risco de hipertensão e diabetes daqueles idosos portadores destas condições crônicas. 

Discordance between the patient's and physician's global assessment in rheumatoid arthritis: Data from the REAL study-Brazil

Background

Discordance between patient’s global assessment (PtGA) and physician’s global assessment (PhGA) has been described in rheumatoid arthritis (RA). Understanding the reasons for this discrepancy is important in the context of treat-to-target treatment strategy.

Objective

To assess the determinants of PtGA and PhGA and factors associated with discordance between them.

Methods

The REAL study included RA patients from Brazilian public health centers. Clinical, laboratory and outcomes measures were collected. PtGA and the PhGA were rated on a visual analog scale and analyzed. Three groups were defined: no discordance (difference between PtGA and PhGA within 3 cm), positive discordance (PtGA exceeding PhGA by >3 cm), and negative discordance (PtGA less than PhGA by >3 cm). Multivariate regression analysis was used to identify determinants of PtGA and PhGA and their discordance.

Results

1115 patients (89,4% female, mean age 56.7y and median disease duration of 12.7y) were enrolled. Two factors were associated with PtGA in the final multivariate model: one point increase in the pain scale leads to an increase of 0.62 in PtGA; one point increase in HAQ increases by 9,25 points the PtGA. The factors associated with PhGA were pain scale, number of tender and swollen joints (NTJ and NSJ), positive RF, ESR, HAQ-DI and use of corticosteroids. Discordance between patient and physician was found in 30.52%: positive discordance in 24.6% and negative discordance in 5.92%. An increase of one point in the NSJ was associated with a 12% increase in the chance of negative discordance. The chance of positive discordance increased by 90% and 2% for each unit increased in HAQ-DI and pain scale respectively. Finally, the chance of positive discordance decreased by 3% for each point increased in NTJ and by 15% for each point increased in NSJ.

Conclusion

In one-third of the assessments, there was disagreement between PtGA and PhGA (a positive discordance was found in 80% of them). Pain and function were determinants for patients to estimate disease activity, while swollen joints was the main factor related to a worse physician’s evaluation. These data show how different can be the perspectives of patients and assistants.
