Respiratory symptoms are common in stiff person syndrome spectrum disorders and are associated with number of body regions involved.

BACKGROUND AND PURPOSE: Stiff person syndrome (SPS) spectrum disorders (SPSSD) cause spasms and rigidity throughout different body regions and can be associated with apnea and acute respiratory failure. There are limited data on the prevalence and predictors of respiratory symptoms with spasms (RSwS) in SPSSD. We sought to characterize the spirometry patterns and the frequency and predictors of RSwS in a large SPSSD cohort. METHODS: Participants were recruited from the Johns Hopkins SPS Center between 1997 and 2021, as part of an ongoing, longitudinal observational study. Medical records were reviewed to assess demographics and clinical characteristics. Data were analyzed using descriptive statistics and multivariable logistic regression models. RESULTS: One-hundred ninety-nine participants (mean age = 53.4 ± 13.6 years, median time to diagnosis = 36 [IQR 66] months, 74.9% women, 69.8% White, 62.8% classic SPS phenotype) were included in final analyses; 35.2% of participants reported RSwS, of whom 24.3% underwent spirometry as part of routine clinical care. Obstructive (23.5%) and restrictive (23.5%) patterns were most commonly observed in those with SPSSD. An increasing number of body regions involved predicted the presence of RSwS (odds ratio [OR] = 1.95, 95% confidence interval [CI] = 1.50-2.53); those with ≥5 body regions involved (vs. ≤4) had higher odds (OR = 6.19, 95% CI = 2.81-13.62) of experiencing RSwS in adjusted models. Two patients died from SPSSD-associated respiratory compromise. CONCLUSIONS: RSwS are common in SPSSD and may be predicted by an increasing number of body regions involved by SPSSD. Close clinical monitoring and having a low threshold to obtain spirometry should be considered in people with SPSSD.

Socioeconomic disparity is associated with faster retinal neurodegeneration in multiple sclerosis.

Disease course in multiple sclerosis is notably heterogeneous, and few prognostic indicators have been consistently associated with multiple sclerosis severity. In the general population, socioeconomic disparity is associated with multimorbidity and may contribute to worse disease outcomes in multiple sclerosis. Herein, we assessed whether indicators of socioeconomic status are associated with disease progression in patients with multiple sclerosis using highly sensitive imaging tools such as optical coherence tomography, and determined whether differential multiple sclerosis management or comorbidity mediate any observed socioeconomic status-associated effects. We included 789 participants with longitudinal optical coherence tomography and low contrast letter acuity (at 1.25 and 2.5%) in whom neighbourhood- (derived via nine-digit postal codes) and participant-level socioeconomic status indicators were available ≤10 years of multiple sclerosis symptom onset. Sensitivity analyses included participants with socioeconomic status indicators available ≤3years of symptom onset (n = 552). Neighbourhood-level indicators included state and national area deprivation indices, median household income and the Agency for Healthcare Research and Quality (AHRQ) Socioeconomic Status Index. Participant-level indicators included education level. Biannual optical coherence tomography scans were segmented to quantify thickness of the composite macular ganglion cell+inner plexiform (GCIPL) layer. We assessed the association between socioeconomic status indicators and GCIPL atrophy or low contrast letter acuity loss using mixed models adjusting for demographic (including race and ethnicity) and disease-related characteristics. We also assessed socioeconomic status indicators in relation to multiple sclerosis therapy changes and comorbidity risk using survival analysis. More disadvantaged neighbourhood-level and patient-level socioeconomic status indicators were associated with faster retinal atrophy. Differences in rate of GCIPL atrophy for individuals in the top quartile (most disadvantaged) relative to the bottom quartile (least) for state area deprivation indices were -0.12 µm/year faster [95% confidence interval (CI): -0.19, -0.04; P = 0.003], for national area deprivation indices were -0.08 µm/year faster (95% CI: -0.15, -0.005; P = 0.02), for household income were -0.11 µm/year faster (95% CI: -0.19, -0.03; P = 0.008), for AHRQ Socioeconomic Status Index were -0.12 µm/year faster (95% CI: -0.19, -0.04) and for education level were -0.17 µm/year faster (95% CI: -0.26, -0.08; P = 0.0002). Similar associations were observed for socioeconomic status indicators and low contrast letter acuity loss. Lower socioeconomic status was associated with higher risk of incident comorbidity during follow-up. Low socioeconomic status individuals had faster rates of therapy escalation, suggesting the association between socioeconomic status and GCIPL atrophy may not be explained by differential contemporaneous multiple sclerosis therapy management. In conclusion, socioeconomic disparity is associated with faster retinal neurodegeneration in multiple sclerosis. As low socioeconomic status was associated with a higher risk of incident comorbidities that may adversely affect multiple sclerosis outcomes, comorbidity prevention may mitigate some of the unfavourable socioeconomic status-associated consequences.

Depression in multiple sclerosis across the adult lifespan.

OBJECTIVES: The objective of this study is to examine the burden of depressive symptoms across the adult age span in people with multiple sclerosis (MS) and test if the relationship between depressive symptoms and MS characteristics vary across age groups. METHODS: In analyses of the MS Partners Advancing Technology and Health Solutions (MS PATHS) network of adults with MS, we compared the prevalence of depression in MS PATHS with non-MS controls across age and evaluated for effect modification by age in the association between depressive symptoms and clinical and neuroperformance measures via multivariable-adjusted regression models. RESULTS: In total, 13,821 individuals with MS were included. The prevalence of depression was higher in MS versus non-MS controls, but was similar between men/women across age. The association between depression and processing speed (PST; p for interaction = 0.009) or walking speed (p for interaction = 0.04) varied by age. For example, younger depressed individuals had 0.45 standard deviation (SD) (95% confidence interval (CI) = -0.62, -0.29) worse PST Z-scores versus non-depressed younger participants, whereas older depressed individuals had 0.20 SD (95% CI = -0.32, -0.08) worse PST Z-scores versus non-depressed older participants. CONCLUSION: Depressive symptoms and age should be considered when interpreting measures of walking speed and cognitive function; these findings may have implications for analyses of neuroperformance change.

Expanding clinical profiles and prognostic markers in stiff person syndrome spectrum disorders.

OBJECTIVE: To describe the clinical features of a cohort of individuals with stiff person syndrome spectrum disorders (SPSD) and identify potential early predictors of future disability. BACKGROUND: There is a need to better understand the full spectrum of clinical and paraclinical features and long-term impact of SPSD. DESIGN/METHODS: Observational study from 1997 to 2022 at Johns Hopkins. Clinical phenotypes included classic SPS, partial SPS (limb or trunk limited), SPS-plus (classic features plus cerebellar/brainstem involvement), and progressive encephalomyelitis with rigidity and myoclonus (PERM). Outcome measures were modified Rankin scale (mRS) and use of assistive device for ambulation. Multivariate logistic regression was used to assess significant predictors of outcomes. RESULTS: Cohort included 227 individuals with SPSD with mean follow-up of 10 years; 154 classic, 48 SPS-plus, 16 PERM, and 9 partial. Mean age at symptom onset was 42.9 ± 14.1 years, majority were white (69.2%) and female (75.8%). Median time to diagnosis was 36.2 months (longest for SPS-plus and PERM) and 61.2% were initially misdiagnosed. Most had systemic co-morbidities and required assistive devices for ambulation. Female sex (OR 2.08; CI 1.06-4.11) and initial brainstem/cerebellar involvement (OR 4.41; CI 1.63-14.33) predicted worse outcome by mRS. Older age at symptom onset (OR 1.04; CI 1.01-1.06), female sex (OR 1.99; CI 1.01-4.01), Black race (OR 4.14; CI 1.79-10.63), and initial brainstem/cerebellar involvement (OR 2.44; CI 1.04-7.19) predicted worse outcome by use of assistive device. Early implementation of immunotherapy was associated with better outcomes by either mRS (OR 0.45; CI 0.22-0.92) or use of assistive device (OR 0.79; CI 0.66-0.94). CONCLUSIONS: We present the expanding phenotypic variability of this rare spectrum of disorders and highlight potential predictors of future disability.

The many faces of gastrointestinal dysfunction in stiff person syndrome spectrum disorders.

Introduction: The effect of stiff person syndrome spectrum disorders (SPSD) on the gastrointestinal tract (GIT) is unknown. This case series aims to characterize the prevalence and types of GI dysfunction in individuals with SPSD. Methods: A retrospective chart review included individuals diagnosed with SPSD with descriptors of GI symptoms in their medical records. SPSD phenotypes, type of motility test performed, and dysmotility pattern (upper, lower, or diffuse) were assessed. Descriptive statistics and univariate chi-square analyses were utilized. Results: Of 240 individuals with SPSD, 32% reported GI symptoms, most were female (83.1%), and white (74%), with a median age at time of GI symptom onset of 50 ± 13 years. Most common symptoms reported were dysphagia (45%), constipation (40%), and nausea/vomiting (23%). Most individuals had classic SPS (47%) followed by SPS-plus (29%) and 82.9% were positive for serum antiGAD65 antibodies. Of 36 patients that underwent at least one GI motility test, 26 had evidence of upper, lower, or diffuse GI dysmotility (44.4%, 17%, and 4%, respectively). The group who did not undergo testing had a higher proportion of patients with DM. Discussion: There is a high prevalence of GI symptoms and transit abnormalities in patients with SPSD. Future prospective, longitudinal studies are warranted to further assess GI symptoms in the context of SPSD and to determine if individuals with GI symptoms differ in prognosis or treatment response from those without GI symptoms. In the meantime, there should be a low threshold for motility testing in patients with SPSD.

Recurrent Optic Neuritis and Perineuritis Followed by an Unexpected Discovery: From the National Multiple Sclerosis Society Case Conference Proceedings.

We describe a woman with a history of relapsing acute optic neuritis and perineuritis. Testing failed to confirm a specific diagnosis; hence, she was diagnosed with seronegative neuromyelitis optica spectrum disorder and treated with the immunotherapy rituximab, later in conjunction with mycophenolate mofetil. She achieved a durable remission for 9 years until she presented with paresthesia affecting her left fifth digit, right proximal thigh, and left foot, while also reporting a 25-pound weight loss over the prior 3 months. New imaging demonstrated a longitudinally extensive and enhancing optic nerve, in conjunction with multifocal enhancing lesions within the spinal cord, in a skip-like distribution. The differential diagnosis is discussed.

Cognitive and Mood Profiles Among Patients With Stiff Person Syndrome Spectrum Disorders.

An emerging body of evidence suggests that changes in cognitive and emotional function are common aspects of stiff person spectrum disorders (SPSD). We sought to examine the pattern of cognitive impairment and psychiatric symptoms in SPSD. Methods: A retrospective review of medical records was conducted for patients seen at the Johns Hopkins Stiff Person Syndrome (SPS) center from 1997 to January 1st, 2020. Individuals who had received formal cognitive testing as part of routine clinical care for patient-reported cognitive changes were included. Demographics, prevalence of cognitive impairment, psychoactive medication use, and clinically significant psychiatric symptoms were described. Results: Out of 205 patients screened, 20 completed cognitive testing (75% female, mean age 47.4 years). The most common domains of impairment were verbal learning and recall memory (n = 14, 70%), verbal fluency (n = 10, 50%), processing speed (n = 8, 40%), and attention (n = 8, 40%). 9/11 patients assessed for depression reported clinically significant symptoms, and 4/9 patients assessed for anxiety reported clinically significant symptoms. Conclusions: Screening for cognitive impairment in SPSD should utilize testing that assesses verbal learning and recall, phonemic verbal fluency, attention, and processing speed. Moreover, it is important to evaluate for co-existing depression and anxiety symptoms, as these are common in SPSD.

The impact of socioeconomic status on mental health and health-seeking behavior across race and ethnicity in a large multiple sclerosis cohort.

BACKGROUND: Psychiatric symptoms are common in multiple sclerosis (MS) and may contribute to worse MS outcomes. Previous studies suggest the burden of symptoms may vary by race, ethnicity and socioeconomic status (SES). Our objective was to expand upon this previous work and explore the associations between SES, race, and ethnicity, as predictors of psychiatric symptoms, mental health attitudes, and health-seeking behavior in patients with MS. METHODS: Persons with MS answered a national web-based survey including demographic characteristics (including race, ethnicity and measures of SES), mental health attitudes, the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Modified Fatigue Impact Scale 5-item version (MFIS-5), and the Alcohol Use Disorders Identification Test (AUDIT). The survey also queried mental health availability and perceptions of care. We measured neighborhood-level SES (nSES) of each participant using the Agency for Healthcare Research and Quality (AHRQ) index that was calculated from 5-digit postal codes. Other indicators of participant-level SES included education level and self-reported household income. We assessed the association between race, ethnicity, and neighborhood/participant-level SES indicators and affective symptom burden using generalized linear models that were adjusted for age, sex, and MS characteristics. RESULTS: 2095 participants answered the survey (mean AHRQ index 54.6 ± 5.4, age 51.3 ± 12.2 years, 7% Black/African American, 5.4% Hispanic/Latino, and 81.8% female). Those in the lowest quartile of nSES (most disadvantaged) were more likely to be either Black/African American or Hispanic/Latino as compared to those in highest quartile (least disadvantaged). Those in the lowest quartile of nSES had higher mean MFIS-5 (1.02 points; 95% CI: 0.39, 1.43), PHQ-9 (1.24 points; 95% CI: 0.49, 1.98), and GAD-7 (0.69 points; 95% CI: -0.01, 1.38) scores relative to those in the highest quartile. Of those who consumed alcohol (n = 1489), participants in the lowest AHRQ quartile had lower mean AUDIT scores (-0.73 points; 95% CI: -1.18, -0.29) as compared to those in higher quartiles. Race and ethnicity were not associated with self-reported psychiatric symptom burden in this cohort. SES was also associated with self-reported improvement of symptoms after receiving mental health care. A higher proportion of Black/African American (44.1% vs 30.2%, p = 0.003) and Hispanic/Latino (49.1% vs 30.6%, p<0.001) participants were more likely to report they would "definitely go" receive mental health care if services were co-located with their MS care as compared to white and Non-Hispanic/Latino participants, respectively. CONCLUSION: Higher SES was associated with a lower burden of psychiatric symptoms and with a higher likelihood of self-reported symptom recovery after receiving mental health treatment. Attitudes regarding mental health care delivery in MS varied according to racial and ethnic background. Future longitudinal studies in more diverse populations should assess whether co-location of mental health services with MS care helps to reduce the gap between access and need of mental health care in MS.

Perceptions and Preferences Regarding Multiple Sclerosis Research Among Racial and Ethnic Groups.

BACKGROUND: For unclear reasons, minorities have been historically underrepresented in multiple sclerosis (MS) clinical trials. We hypothesized that different perceptions and preferences about research participation among racial and ethnic groups contribute to this imbalance. METHODS: Members of the MS Minority Research Engagement Partnership Network developed a Web-based survey in English and Spanish on research impressions, concerns, and preferences regarding study attributes among people with MS. Invitations to take the survey were distributed by network members and partner organizations. RESULTS: We included 2599 participants with MS (2111 White, 215 African American; 188 Hispanic). Consistently disliked study attributes included potential harms to health and confusing study information. Compared with White and non-Hispanic participants, respectively, African American (odds ratio [OR] = 2.05, P ≤ .001) and Hispanic (OR = 1.79, P = .003) participants were more concerned about being used by the research team. Hispanic participants were more concerned about research participation carrying risks to their legal status (OR = 1.70, P = .001). Hispanic (OR = 3.18, P ≤ .001) and African American (OR = 5.51, P ≤ .001) participants were more likely to prefer for the study to benefit their own racial/ethnic group. A top concern across all groups was not being fully informed about the research. CONCLUSIONS: We found strong support for research across racial and ethnic groups; however, minority groups have specific concerns regarding mistrust, receiving poor-quality care, unemployment, health insurance, and legal status. Investigators wanting to recruit a diverse study population are advised to show how they have addressed these concerns and to communicate how the research will advance the science and literature and result in better care and/or other benefits to underrepresented communities.

Mammography correlates to better survival rates in breast cancer patients: a 20-year experience in a University health institution.

Breast cancer (BC) is the most common malignancy in women. We retrieved medical records from >2,000 Chilean BC patients over the 1997-2018 period. The objective was to assess changes in clinical presentation or prognosis of our patients throughout these 20 years of practice. Although most variables did not display significant variations, we observed a progressive increase in stage IV BC over this period. Our data showed that tumour stage III/IV or HER2-enriched subtype tumours were associated with poorer prognosis. In contrast, we found that patients diagnosed by mammography had better overall survival. We speculate that better screenings and more sensitive imaging could explain the unexpected rise in stage IV cases. Our results support mammography screenings as an effective measure to reduce BC-related mortality.

Safety and preliminary efficacy of intranasal insulin for cognitive impairment in Parkinson disease and multiple system atrophy: A double-blinded placebo-controlled pilot study.

Parkinson disease (PD) is associated with cognitive impairment. We aimed to determine the effects of intranasal insulin (INI) on cognition and motor performance in PD. This was a proof of concept, randomized, double-blinded, placebo-controlled trial evaluating the effects of 40 international units (IU) of insulin or saline once daily for four weeks on cognitive and functional performance. Of 16 subjects enrolled, eight in the INI group and six in the placebo group completed verbal fluency (FAS), Unified Parkinson Disease Scale (UPDRS), and modified Hoehn and Yahr scale (HY, PD severity) at baseline and post-treatment and were included in the analyses. After treatment, the INI group had a better total FAS score (p = 0.02) (41 ± 8.2 vs. 30.8 ± 7.1, mean ±SD, p = 0.02) compared to the placebo group. The INI group also had improved HY (p = 0.04) and UPDRS-Motor (Part III) (p = 0.02) scores when compared to baseline. One INI treated patient with multiple system atrophy (MSA) remained stable and did not show disease progression. The placebo group had no change. INI administration was well tolerated and there were no hypoglycemic episodes or serious study related adverse events or medications interactions. INI is safe in PD and MSA patients and may provide clinically relevant functional improvement. Larger studies are warranted to determine the INI effect in treatment of cognitive and motor impairment in Parkinson disease. Trial Registration: ClinicalTrial.gov NCT02064166.

Augmented reality and dynamic infrared thermography for perforator mapping in the anterolateral thigh.

Dynamic infrared thermography (DIRT) has been used for the preoperative mapping of cutaneous perforators. This technique has shown a positive correlation with intraoperative findings. Our aim was to evaluate the accuracy of perforator mapping with DIRT and augmented reality using a portable projector. For this purpose, three volunteers had both of their anterolateral thighs assessed for the presence and location of cutaneous perforators using DIRT. The obtained image of these "hotspots" was projected back onto the thigh and the presence of Doppler signals within a 10-cm diameter from the midpoint between the lateral patella and the anterior superior iliac spine was assessed using a handheld Doppler device. Hotspots were identified in all six anterolateral thighs and were successfully projected onto the skin. The median number of perforators identified within the area of interest was 5 (range, 3-8) and the median time needed to identify them was 3.5 minutes (range, 3.3-4.0 minutes). Every hotspot was correlated to a Doppler sound signal. In conclusion, augmented reality can be a reliable method for transferring the location of perforators identified by DIRT onto the thigh, facilitating its assessment and yielding a reliable map of potential perforators for flap raising.

Lower cerebral vasoreactivity as a predictor of gait speed decline in type 2 diabetes mellitus.

Gait speed is an indicator of overall functional health and is correlated with survival in older adults. We prospectively evaluated the long-term association between cerebral vasoreactivity and gait speed during normal walking (NW) and dual-task walking (DTW) in older adults with and without type 2 diabetes mellitus (T2DM). 40 participants (aged 67.3 ± 8.8 years, 20 with T2DM) completed a 2-year prospective study consisting of MRI, blood sampling, and gait assessments. The whole brain vasoreactivity was quantified using continuous arterial spin labeling MRI. Gait speed during DTW was assessed by subtracting serial sevens. Dual-task cost was calculated as the percent change in gait speed from NW to DTW. In the entire cohort, higher glycemic profiles were associated with a slower gait speed. In the diabetic group, lower vasoreactivity was associated with a slower gait speed during NW ([Formula: see text] = 0.30, p = 0.019) and DTW ([Formula: see text] = 0.35, p = 0.01) and a higher dual-task cost ([Formula: see text] = 0.69, p = 0.009) at 2-year follow-up. The participants with T2DM and lower cerebral vasoreactivity had a greater decrease in gait speed during NW and DTW after the 2-year follow-up ([Formula: see text] = 0.17, p = 0.04 and [Formula: see text] = 0.28, p = 0.03, respectively). Longer diabetes duration was associated with a higher dual-task cost ([Formula: see text] = 0.19, p = 0.04) and a greater decrease in gait speed during NW ([Formula: see text] = 0.17, p = 0.02). These findings indicate that in older adults with type 2 diabetes, gait performance is highly dependent on the integrity of cerebrovascular regulation.

Glomerulopatía colapsante con insuficiencia renal terminal de rápida progresión / Collapsing glomerulopathy with rapid progression to terminal renal failure

La glomerulopatía colapsante (GC) constituye una variedad de la glomeruloesclerosis focal y segmentaria. Afecta tanto a la población adulta (40%) como a la infantil (20%); presentándose con mayor frecuencia en hombres jóvenes y afrodescendientes. Clínicamente se presenta como un síndrome nefrótico, con niveles elevados de úrea y creatinina. Se presenta el caso de paciente femenino de 22 años, quien acude por presentar fiebre, edema matutino en miembros inferiores, e intolerancia oral de 9 días de evolución. Al examen físico: Hipertensión arterial y ascitis. La GC es una entidad poco diagnosticada, que progresa rápidamente a insuficiencia renal terminal a pesar de recibir cualquier tratamiento sistémico descrito hasta la actualidad, por lo que amerita mayor investigación en el ámbito terapéutico(AU)

Collapsing glomerulopathy (GC) is a variety of focal segmental glomerulosclerosis. It affects both adult population (40%) and children (20%); it occurs most often in young people, male and of African descent. Clinically it is presented as a nephrotic syndrome, with high levels of urea and creatinine serum. There is insufficient evidence regarding the treatment of this entity, so that steroids and immunosuppressants are used at high doses. We present the case of a 22-year old female, who presented fever, edema in the lower limbs and oral intolerance of 9 days of evolution. Physical examination showed: high blood pressure and ascitis. This nephropathy is an underdiagnosed entity rapidly progressing to kidney failure despite receiving any systemic treatment described until now, so it merits further research in the therapeutic field(AU)

Epilepsia occipital / Occipital lobe epilepsy

Se han hecho innumerables intentos para lograr una definición que incluya toda la semiología y fisiología que envuelve la epilepsia, y tratar de hacerlo ha sido una tarea que ha tomado muchos años. Aunado a ello se ha propuesto una clasificación en diferentes grupos según su inicio y desencadenamiento, como lo son focales y generalizadas. La presente revisión versará acerca de la epilepsia occipital, clasificada antes dentro de las crisis parciales, en las que se han identificado un curso y un pronóstico favorables en el transcurso del tiempo, y que tienen en común un inicio en la edad temprana. Ha sido descrito que algunos de estos trastornos pudieran tener una base genética hereditaria o bien esporádica en otros, lo cual requiere una investigación exhaustiva. Por lo anterior se hace necesaria una revisión completa acerca de la epilepsia occipital, con el fin de dar claridad conceptual, clínica y diagnóstica de este desorden, así como para hacer aportes al conocimiento de la misma en pro de mejorar la calidad de vida y el tratamiento en la práctica clínica de pacientes que se encuentren dentro del espectro de esta enfermedad.

Epilepsy and its overall semiology and physiology have been subject to Innumerable definition attempts which have taken many years of effort. Likewise, a proposal for an epilepsy classification based on onset and precipitating factors was developed dividing seizures into focal and generalized seizures. This article reviews occipital lobe epilepsy which was formerly classified in the partial seizures group characterized by a favorable course and prognosis over time and by onset during early childhood. A possible genetic hereditary origin and that they may be sporadic has been described for some of these problems and still require a thorough investigation. Thus, it is necessary to conduct an extensive review on occipital lobe epilepsy for obtaining conceptual, clinical and diagnostic clarity as well as, to enhance knowledge on this illness for improving quality of life and clinical treatment in patients experiencing this spectrum of disorders.

Piomiositis tropical, un gran simulador de diagnóstico infrecuente / Tropical pyomyositis, a great simulator of uncommon diagnosis

La piomiositis tropical es una infección que afecta al músculo estriado, principalmente de región pélvica y proximal de muslos. Lo excepcional radica en la colonización del músculo estriado, evidenciándose la práctica de ejercicio extenuante como factor predisponente. El Staphylococcus aureus es el principal agente etiológico. La presentación se caracteriza por fiebre, mialgia y limitación funcional. El tratamiento contempla antibioticoterapia y drenaje quirúrgico. Se trata de escolar masculino, 11 años, quien presenta dolor en región inguinal izquierda, aumento de volumen en muslo ipsilateral, fiebre, limitación funcional. Práctica interdiaria de béisbol. Posición antálgica de muslo izquierdo, signos de flogosis en región inguinal y glútea ipsilateral. Paraclínicos: Leucocitosis, neutrofilia, proteína C reactiva elevada. Resonancia magnética nuclear demuestra colección en músculos pelvitrocantéricos. Se indicó antibioticoterapia con Clindamicina y Cefotaxime. Presenta evolución satisfactoria.

Tropical pyomyositis is an infection that affects the striated muscle, mainly of the pelvic and proximal thighs. Seen more frequently in immunocompetent males between 2-10 years. The uncommon fact is the colonization of striated muscle, with the practice of extenuating exercise, as a predisposing factor. Staphylococcus aureus is the main etiological agent. Clinical presentation is characterized by fever, myalgia and functional limitation. Treatment includes antibiotic therapy and surgical drainage. Clinical case: An 11 year old boy, who presents with pain in the left inguinal region, increased volume of the ipsilateral thigh, fever and functional limitation. The patient usually practiced baseball every other day. Physical examination: Antalgic position of the left thigh, phlogosis in inguinal and gluteal ipsilateral regions. Paraclinics: Leukocytosis, neutrophilia, elevated C-reactive protein. Nuclear magnetic resonance demonstrates collection in pelvitrocanteric muscles. Antibiotic therapy with Clindamycin and Cefotaxime were prescribed with a satisfactory evolution.

Use of PCR to demonstrate presence of adenovirus species B, C, or F as well as coinfection with two adenovirus species in children with flu-like symptoms.

Adenovirus (AdV) respiratory infections have usually been associated with species B, C, and E. In this study, we detected 9.4% of AdVs by PCR in 500 nasal swabs from 319 children with influenza-like symptoms. AdV typing by PCR with specific probes showed species C, B, and F as well as coinfection with two species. Coinfection with two AdV species and the presence of species F in respiratory samples are novel findings that should be further investigated.

O comportamento agressivo de crianças do sexo masculino na escola e sua relação com a violência doméstica / Aggressive behaviors of male children in school and its relation to domestic violence

Este trabalho teve como meta estudar o comportamento agressivo de crianças do sexo masculino na escola e sua relação com a violência doméstica. Avaliaram-se 28 crianças do sexo masculino e suas respectivas mães, dentre as quais 14 crianças apresentavam comportamentos agressivos na escola (Grupo A). Estas últimas foram comparadas às 14 crianças do mesmo sexo e nível de renda que não apresentavam tais comportamentos (Grupo B). Os dados foram coletados inicialmente pelas professoras das crianças em três escolas de Ensino Básico de uma cidade do interior de São Paulo. Seguidamente, foram coletados dados com as mães das crianças em visitas domiciliares. Os resultados gerais apontam para a ocorrência de violência em ambos os grupos, porém, com maior incidência e maior severidade, no grupo de crianças agressivas. As considerações finais sinalizam a necessidade de futuros estudos para expandir a compreensão do comportamento agressivo e sua relação com a violência doméstica.
