RESUMEN
BACKGROUND: In November 2018, Mohs micrographic surgery (MMS) was restricted to fellows registered with the Australasian College of Dermatologists. Three new item numbers for the provision of MMS were also introduced. We examine the national and state usage of MMS item numbers based on Medicare claim statistics and Mohs surgeons' self-reported data, noting the impact of the pandemic and the usage of individual item numbers. METHODS: Medicare item number data were obtained from the Medicare Benefits Schedule website for January 2017-December 2021. Self-reported data were collected on an annual basis by the Royal College of Pathologists of Australasia (RCPA) as part of the Quality Assurance Program (QAP) from 2019 onwards. Data were analysed with the Holt-Winters smoothing method for forecasting. RESULTS: An increasing number of MMS claims were processed each year, with a total of 89,183 for the study period. Since November 2018, 97.7% of procedures have been conducted on the head, neck, genitalia, hand, digits, leg (below the knee) or foot. The provision of services across the country was maintained during the pandemic years of 2020-2021, with an increase in services in Queensland. There were discrepancies between the states for procedures performed in greater than six sections; these constituted more than 35% of claims in Queensland and Western Australia compared to less than 15% in other states. The pandemic impacted certain states more than others, with Victoria and the Northern Territory having significantly fewer presentations than predicted (p < 0.05). CONCLUSIONS: Overall, the use of MMS in Australia is in keeping with peer-developed guidelines, despite discrepancies between states. Although certain states were more severely affected by the pandemic, MMS is increasingly used in Australia.

BACKGROUND: There is a need for improvement in informed medical consent to address the lack of standardization and to increase patient engagement. OBJECTIVE: To investigate the use of a video to aid informed consent for Mohs micrographic surgery and evaluate patient understanding, satisfaction, anxiety, and time savings relative to verbal consent. METHODS: A 2-armed randomized controlled trial involving 102 patients compared video-assisted consent with a control group who underwent consent in the standard verbal manner. All participants underwent questionnaire-based testing of knowledge, satisfaction, and anxiety, and the time of each consultation was measured. RESULTS: Patients who watched the video performed significantly better in the knowledge questionnaire compared with the control group (P = .02), were more satisfied with their understanding of the risks of Mohs micrographic surgery (P = .013), and spent less time with their physician (P = .008). Additionally, 78.4% of video group patients reported that they preferred seeing the video before speaking with their physician. LIMITATIONS: The study design may not replicate day-to-day clinical practice. CONCLUSION: Video-assisted consent for Mohs micrographic surgery improves patient knowledge, leads to a better understanding of the risks, and saves physicians time without compromising patient satisfaction and anxiety levels in this study setting.
RESUMEN
To characterize the production patterns of the dengue virus vector Aedes aegypti (L.) (Diptera: Culcidae), pupal surveys were conducted in selected neighborhoods of two major cities in Nicaragua. In León, 833 houses were visited in July and September 2003, corresponding to the beginning and middle of the dengue season; in Managua, 1,365 homes were visited in July 2003. In total, 7,607 containers were characterized, of which 11% were positive for Ae. aegypti larvae and 4% for pupae. In addition to barrels, potted plants and superficial water on tarps and in puddles were identified as highly productive sites. Univariate and multivariate analysis revealed frequency of container use, use of a lid, and rainwater filling as key variables affecting pupal positivity. Importantly, this survey demonstrated the risk associated with the presence of lids, the limited temporal efficacy of temephos, and the lack of association of water availability with risky water storage practices. Finally, we introduce the concept of an efficiency value and an accompanying graphical display system that can facilitate development of targeted pupal control strategies. These data underscore the importance of entomological surveillance of pupal productivity to gather information from which to derive streamlined, efficient, and effective vector control measures to reduce the density of Aedes mosquito larvae and pupae and thus the risk for dengue.

BACKGROUND: Streptococcus pneumoniae causes about 826,000 deaths of children in the world each year and many health facility visits. To reduce the burden of pneumococcal disease, many nations have added pneumococcal conjugate vaccines to their national immunization schedules. Nicaragua was the first country eligible for GAVI Alliance funding to introduce the 13-valent pneumococcal conjugate vaccine (PCV13) in 2010, provided to infants at 2, 4, and 6 months of age. The goal of this study was to evaluate the population impact of the first five years of the program. METHODS: Numbers of visits for pneumonia, pneumonia-related deaths, and bacterial meningitis in both children and adults, and infant deaths between 2008 and 2015 were collected from all 107 public health facilities in León Department. Vital statistics data provided additional counts of pneumonia-related deaths that occurred outside health facilities. Adjusted incidence rates and incidence rate ratios (IRRa) in the vaccine (2011-2015) and pre-vaccine periods (2008-2010) were estimated retrospectively using official population estimates as exposure time. RESULTS: The IRRa for pneumonia hospitalizations was 0.70 (95% confidence interval [CI]: 0.66, 0.75) for infants, and 0.92 (95% CI: 0.85, 0.99) for one year-olds. The IRRa for post-neonatal infant mortality was 0.56 (95% CI: 0.41, 0.77). In the population as a whole, ambulatory visits and hospitalizations for pneumonia, as well as pneumonia-related mortality and rates of bacterial meningitis were lower in the vaccine period. CONCLUSIONS: During the first five years of program implementation, reductions were observed in health facility visits for pneumonia in immunized age groups and infant mortality, which would be hard to achieve with any other single public health intervention. Future study is warranted to understand whether the lack of a booster dose (e.g., at 12 months) may be responsible for the small reductions in pneumonia hospitalizations observed in one year-olds as compared to infants.

Larvae of Aedes albopictus, a mosquito known for transmitting dengue virus, were identified in the city of León, Nicaragua, in 2003. Mosquito larvae were collected from a total of 2,225 residences in the 2 largest cities in Nicaragua during the period from June to September of 2003, and larval Ae. albopictus were identified in 4 homes in León. This represents the 1st detection of Ae. albopictus in a major Nicaraguan urban center, and increased control efforts appear to have eliminated the mosquito subsequently from León. The presence of Ae. albopictus in urban Nicaragua highlights the need for surveillance of areas thought to be free of the mosquito so that early detection and control activities can prevent its spread.

BACKGROUND: In 2010, Nicaragua implemented an adult immunization program with the 23-valent pneumococcal polysaccharide vaccine (PPSV-23) and a pediatric immunization program with the 13-valent pneumococcal conjugate vaccine (PCV-13). We assessed incidence rates of ambulatory visits and hospitalizations for pneumonia and pneumonia-related mortality in adults over the age of 50 years before and after the program's implementation in the Department of León, Nicaragua. METHODS: We collected visit diagnoses from all 107 public health facilities between 2008 and 2012 in León. We compared incidence rates of ambulatory visits for pneumonia, pneumonia hospitalizations, and pneumonia-related mortality in the pre-vaccine (2008-2009) and vaccine (2011-2012) periods among older adults using Poisson regression with generalized estimating equations (GEE), controlling for age group, municipality, and proportions of adults who were immunized against influenza. Exposure time was estimated by official municipality population estimates. RESULTS: We did not observe lower incidence rates of ambulatory visits or hospitalizations for pneumonia among adults during the vaccine period versus the pre-vaccine period. However, pneumonia-related mortality was lower in the vaccine period versus the pre-vaccine period, with an adjusted incidence rate ratio (IRRa) of 0.73 (0.56, 0.94) among adults aged 50-64 years, and 0.55 (0.43, 0.70) among adults aged ≥65 years. CONCLUSIONS: These early results following introduction of a combined pediatric and adult pneumococcal immunization program in Nicaragua show a probable impact of the program on the reduction of pneumonia-related deaths in older adults, but a less clear impact on the reduction of health facility visits for pneumonia.

Imiquimod is the first of a new class of drugs (immune response modifiers) to become commercially available. It is approved in many countries for the treatment of genital warts caused by the human papilloma virus infection. However, there are reports of its use in a variety of dermatological conditions, such as basal cell carcinomas, actinic keratoses, lentigo maligna, common warts and molluscum contagiosum. Its mechanism of action is through stimulation of the T helper cell Type 1 (Th1) immune response via activation of cell surface pathogen recognition receptors (mainly toll-like receptor 7). This activation stimulates the immune system's own defence mechanism against both virally infected and tumour cells. Imiquimod and other analogues show promise in the prophylactic treatment of skin tumours in some patients, especially those who are immunocompromised.

BACKGROUND: In 2010, Nicaragua became the first developing nation to add 13-valent pneumococcal conjugate vaccine (PCV-13) to its national immunization schedule, using a "3+0" dosing schedule. We assessed changes in incidence rates of health facility visits for childhood pneumonia and infant mortality after PCV-13 introduction in the Department of León, Nicaragua. METHODS: We collected visit diagnoses from all 107 public health facilities in León between 2008 and 2012. We compared rates of pneumonia hospitalizations, ambulatory visits for pneumonia and infant mortality during the prevaccine (2008-2010) and vaccine (2011-2012) periods among different age groups of children using generalized estimating equations, accounting for clustering by municipality. Exposure time was estimated by official municipality population estimates. RESULTS: The adjusted incidence rate ratio for pneumonia hospitalization in the vaccine versus prevaccine period was 0.67 (0.59-0.75) among infants and 0.74 (0.67-0.81) among 1-year olds. The adjusted incidence rate ratio for ambulatory visits for pneumonia was 0.87 (0.75-1.01) among infants, and 0.84 (0.74, 0.95) among 1-year olds. The adjusted incidence rate ratio for infant mortality was 0.67 (0.57-0.80). We also observed lower rates of health facility visits for pneumonia among age groups (2- to 4-year old and 5- to 14-year old) not eligible to receive PCV-13. CONCLUSIONS: Within the first 2 years of a PCV-13 immunization program in Nicaragua, we observed lower rates of hospitalizations and ambulatory visits for pneumonia among children of all ages and a lower infant mortality rate. Lower rates of pneumonia among age groups not eligible to receive PCV-13 suggest an indirect effect of the vaccine.

Leptospirosis is an epidemic-prone zoonotic disease that occurs worldwide, with more than 500,000 human cases reported annually. It is influenced by environmental and socioeconomic factors that affect the occurrence of outbreaks and the incidence of the disease. Critical areas and potential drivers for leptospirosis outbreaks have been identified in Nicaragua, where several conditions converge and create an appropriate scenario for the development of leptospirosis. The objectives of this study were to explore possible socioeconomic variables related to leptospirosis critical areas and to construct and validate a vulnerability index based on municipal socioeconomic indicators. Municipalities with lower socioeconomic status (greater unsatisfied basic needs for quality of the household and for sanitary services, and higher extreme poverty and illiteracy rates) were identified with the highest leptospirosis rates. The municipalities with highest local vulnerability index should be the priority for intervention. A distinction between risk given by environmental factors and vulnerability to risk given by socioeconomic conditions was shown as important, which also applies to the "causes of outbreaks" and "causes of cases".

BACKGROUND: Although the pentavalent rotavirus vaccine was highly efficacious against rotavirus diarrhea in clinical trials, the effectiveness of vaccine under field conditions in the developing world is unclear. In October 2006, Nicaragua became the first developing nation to implement universal infant immunization with the pentavalent rotavirus vaccine. To assess the effect of the immunization program, we examined the incidence of diarrhea episodes between 2003 and 2009 among children in the state of León, Nicaragua. METHODS: We extracted data on diarrhea episodes from health ministry records. We used scaled Poisson regression models to estimate diarrhea incidence rate ratios for the period following the program's implementation to the period before implementation. RESULTS: Following implementation of the immunization program, diarrhea episodes among infants were reduced (incidence rate ratios: 0.85, 95% confidence interval: 0.71-1.02) during the rotavirus season, but appear to have increased during other months. CONCLUSIONS: Although the immunization program appears effective in reducing diarrhea episodes during the rotavirus season, a large burden of diarrhea still persists during the remainder of the year.

Multiple therapeutic options are available for treatment of Bowen's disease. The choice of therapy depends on clinical circumstance and medical practitioner experience. Newer therapies have more extensive support from the literature, but more established therapies may be preferred because of accessibility, cost and efficacy. An overview of the current therapeutic options for Bowen's disease is presented.

A prospective study was conducted to assess general practitioners' diagnostic skills in a referral setting. The primary objective was to identify general practitioners' strengths and weaknesses in diagnosing a broad spectrum of skin conditions. The diagnoses of 315 skin conditions made by 165 general practitioners were compared with a reference standard. The reference standard was made up of 73 histopathological diagnoses, 119 dermatologists' clinical diagnoses and 123 dermatologists' diagnoses plus follow up. The diagnoses assigned by referring general practitioners were consistent with dermatologists' clinical diagnoses and histology (where available) in 57% of cases. General practitioners made the correct diagnosis in 44% of cases when compared with histopathology. General practitioners were generally good at diagnosing conditions such as acne, warts, rosacea, molluscum contagiosum, vitiligo and skin tags. The proportion of correct diagnoses for premalignant and malignant skin tumours was 47%, and that of skin rashes requiring a diagnosis was 44%. Further education of general practitioners would help to improve their diagnostic skills in certain skin conditions.

Glomuvenous malformations (MIM 138000) are rare vascular malformations consisting of glomus cells, and in affected individuals, lesions may appear in any number anywhere on the body. We analysed the DNA of one family with hereditary glomuvenous malformations and identified the mutation causing the disease in the glomulin gene on chromosome 1 p22. The deletion started at base pair 157: 157delAAGAA, which is a deletion of five base pairs. This mutation has been found in Europe, the USA and Australia, suggesting a founder effect with common ancestry. Thus far, no second-hit mutation for the 157delAAGAA mutation has been identified.

A study of the incidence and characterization of bacteria multi-drug resistance isolated from 750 milk samples of cows affected by subclinical mastitis in middle west region of São Paulo, Brazil, was carried out. Staphylococci (75.8%) (mainly represented by Staphylococcus aureus andStaphylococcus epidermidis) and Escherichia coli(7.1 % ) were most frequently isolated bacteria. Most milk samples yielded pure cultures, but associations of pathogens were found in some samples. In vitro multi-drug resistance to six antibiotics (penicillin, ampicillin, dicloxacillin, streptomycin, tetracycline and oxacillin), was observed only among Gram-negative isolates and in some Staphylococcus aureus (39.9%) strains. Remaining Gram positive bacteria, were all sensitive to drugs tested. Multi-drug resistance in mastitogenic bacteria remain a problem difficult to be solved or controlled, mainly by short term programmes.
Foram analisadas a incidência e a multi-resistência a drogas antimicrobianas em bactérias patogênicas isoladas de 750 amostras de leite de vacas com mastite sub-clínica, na região-centro oeste do Estado de São Paulo. Os microorganismos do gênero Staphytococcus (75,8%), principalmente representados pelo S. aureuse S. epidermes, e a Escherichia coli (7,1%) foram as bactérias mais freqüentemente isoladas. A maioria dos agentes etiológicos apresentou-se em cultura pura, emboraassociações de microorganismos tenham sido encontradas em algumas amostras. A resistência múltipla a drogas antimicrobianas (penicilina, ampicilina, dicloxacilina, estreptomicina, tetraciclina e oxacilina) foi observada somente entre bactérias Gram negativas e em algumas linhagens de S. aureus (39,9%). Os demais agentes bacterianos Gram positivos demonstraram sensibilidade às drogas testadas. Os problemas conseqüentes da resistência múltipla a drogas constituem um obstáculo àterapêutica e de difícil solução, principalmente através de programas de controle a curto prazo.
RESUMEN
Os autores investigaram quantitativamente a resistência a drogas em 82 amostras de enterobactérias, isoladas de animais silvestres, no Município de Botucatu. A seleção das linhagens bacterianas ficou subordinada a uma determinação de seus níveis de resistêncica à sulfadiazina, ao sulfato de Kanaminina, ao clorafenicol, à cefalotina sódica, à hetaciclina potássica, ao cloridrato de tetraciclina e ao sulfato de estreptomicina. Levando-se em consideração os níveis de resistência apresentados, foi possível caracterizar uma população resistente e outra sensível, com relação às seis primeiras drogas. Relativamente ao sulfato de estreptomicina, somente uma população sensível foi encontrada. Resistência exclusiva à sulfadiazina foi observada em 29 amostras de Escherichia coli 27 amostras de Proteus sp, e duas amostras de Salmonella sp (AU).

El nevo piloso gigante congénito, es una patología rara con una incidencia de 1 por cada 30.000 a 100.000 individuos. Se presenta con un tamaño mayor a los 20cm. Puede abarcar entre el 15 y el 35del cuerpo ocupando el tronco, un miembro, etc. Se presenta pigmentado, por lo general de forma dispareja, variando entre el castaño claro y el negro intenso, de consistencia semejante al caparazón de la tortuga y cubierto de pelos largos y gruesos. Comunicamos el caso de 3 niños que al nacimiento mostraron un nevo piloso gigante y múltiples nevos de menor tamaño. Esta Patología requiere extirpación quirúrgica agresiva por motivo estético y reducción del riesgo de degeneración hacia melanoma. En todos estos pacientes debe considerarse el diagnóstico de melanosis neurocutánea por lo que es preciso un seguimiento clínico y de neuroimagen, misma que no tiene tratamiento curativo.
A giant congenital hairy nevus is a rare pathology with an incidence of 1 for every 30,000 to 100,000 person. It is characterized for having a size greater than 20 cm, the color varies from brown to black, and surface texture may vary from smooth to warty and covered by long thick hairs. We have clinical cases of three children that when born had gigantic hairy nevus and multiple nevus of smaller size. This pathology requires surgical removal due to esthetics and the decrease risk of getting melanoma. In these patients we should consider a possible diagnosis of neurocutaneous melanosis a reason why image studies should be done.
