RESUMEN

An acute aseptic meningitis has been occasionally observed on intravenous polyclonal human immunoglobulin therapy. Since case reports cannot be employed to draw inferences about the relationships between immunoglobulin therapy and meningitis, we conducted a systematic review and meta-analysis of the literature. Eligible were cases, case series, and pharmacovigilance studies. We found 71 individually documented cases (36 individuals ≤ 18 years of age) of meningitis. Ninety percent of cases presented ≤ 3 days after initiating immunoglobulin therapy and recovered within ≤ 7 days (with a shorter disease duration in children: ≤ 3 days in 29 (94%) cases). In 22 (31%) instances, the authors noted a link between the onset of meningitis and a rapid intravenous infusion of immunoglobulins. Cerebrospinal fluid analysis revealed a predominantly neutrophilic (N = 46, 66%) pleocytosis. Recurrences after re-exposure were observed in eight (N = 11%) patients. Eight case series addressed the prevalence of meningitis in 4089 patients treated with immunoglobulins. A pooled prevalence of 0.6% was noted. Finally, pharmacovigilance data revealed that meningitis temporally associated with intravenous immunoglobulin therapy occurred with at least five different products. In conclusion, intravenous immunoglobulin may cause an acute aseptic meningitis. The clinical features remit rapidly after discontinuing the medication.

RESUMEN

BACKGROUND: Reviews on Down syndrome do not or only marginally address the issue of kidney and urogenital tract abnormalities, and lower urinary tract dysfunctions. Hence, we performed a meta-analysis of the literature.  METHODS: A literature search was undertaken in the Library of Medicine, Web of Science and Excerpta Medica. The search algorithm combined various keywords: (Down syndrome OR trisomy 21 OR mongolism) AND (kidney OR urinary tract OR bladder) AND (malformation OR dysfunction OR anomaly OR abnormality OR size). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used. RESULTS: Eight case-control studies were retained for the final analysis. Three studies addressed the prevalence of kidney and urogenital tract abnormalities: an increased pooled relative risk of 5.49 (95%-CI: 1.78-16.93) was observed in Down syndrome. Penile malformations, obstructive malformations (including urethral valves), dilated urinary tract system, and kidney hypodysplasia were especially common. Three reports addressed the prevalence of lower urinary tract dysfunction: an increased pooled relative risk of 2.95 (95%-CI: 1.15-7.56) was observed. Finally, an autoptic study and an ultrasound study disclosed a reduced kidney size in Down syndrome. CONCLUSIONS: This meta-analysis indicates that abnormalities of the kidney and urogenital tract, lower urinary tract dysfunctions, and a reduced kidney size present with an increased frequency in individuals with Down syndrome.

RESUMEN

In rural sub-Saharan Africa, knowledge of non-communicable diseases such as high blood pressure (BP) is rather limited. This report provides information about a BP screening in Mata Sector, a rural region in Southern Province of Rwanda. Community-based, house-to-house screening was performed between February and July 2020 on more than 7000 inhabitants. The screening was conducted by a local team composed by 20 community health care workers, five community health care supervisors, and one nurse with hypertension surveillance training. BP and heart rate were recorded after 5 min of resting, using a validated automated oscillometric OMRON M6 IT-HEM-7322-E monitor with Intelli Wrap Cuff (HEM-FL31-E) technology. The mean of the second and third value was retained. BP was normal (<140/90 mm Hg) in 6340 (88%) and elevated in 863 (12%) participants with 95% of unawareness. Grade 1 (140-159/90-99 mm Hg) hypertensive BP readings were detected in 697 (81%), grade 2 (160-179/100-109 mm Hg) in 134 (16%), and grade 3 (≥180/≥110 mm Hg) in 32 (3.7%) individuals. The prevalence of hypertensive readings was significantly age-dependent. Additionally, a slightly greater proportion of participants with high BP (14% versus 11%) had a body mass index (BMI) ≥ 25.0 kg/m2. Also resting heart rate was higher in individuals with high BP (82 versus 77 beats/min). Although individuals identified with occasionally elevated BP values need further confirmatory measurements to establish the diagnosis of hypertension, these data suggest that high BP represents a noteworthy and preventable reason of concern within sub-Saharan Africa.

RESUMEN

INTRODUCTION: Worldwide, arterial hypertension is the foremost preventable and modifiable cardiovascular risk factor. In addition to lifestyle changes, recent international guidelines recommend single-pill, low-dose combinations as initial treatment strategy. We investigated whether this approach is feasible in a rural sub-Saharan Africa setting. METHODS: Diagnosis of hypertension was established over three sets of blood pressure measurements, performed according to the European Society of Hypertension recommendations by trained personnel, using a validated, automated, oscillometric device OMRON M7 IT-HEM-7322-E. In 98 individuals with arterial hypertension, a once-daily, single-pill combination of olmesartan, amlodipine, and hydrochlorothiazide was prescribed at an appropriate dose. Patients were instructed on its administration and potential side effects and encouraged towards lifestyle modifications. The treatment regimen was adjusted, if needed, at each outpatient clinic scheduled after 4, 8, 12, and 16 weeks. RESULTS: Seventy-nine patients (aged 61 [53-70] years; median and interquartile range) strictly adhered to the treatment schedule, while 19 individuals (70 [65-80] years) dropped out. Blood pressure was < 140/90 mmHg after 4 weeks in 44 (56%), after 8 weeks in 62 (78%), after 12 weeks in 69 (87%), and after 16 weeks in 74 (94%) participants. Excellent tolerance was reported. CONCLUSIONS: These results provide real-life evidence that hypertension management with a once-daily, single-pill combination of olmesartan, amlodipine, and hydrochlorothiazide as initial treatment is feasible and effective also in a rural sub-Saharan setting. Single-pill combinations should be made available also in rural and remote areas in low- and middle-income countries as a reliable first-line treatment strategy.

RESUMEN

BACKGROUND: A large, cross-border outbreak of nontyphoidal salmonellosis connected to chocolate product consumption was recently reported. This occurrence motivated us to conduct a comprehensive review of existing literature concerning outbreaks of nontyphoidal salmonellosis associated with chocolate consumption. METHODS: We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO CRD42022369023) in 3 databases: U.S. National Library of Medicine, Web of Science and Excerpta Medica. Google Scholar and the bibliography of each identified report were also screened. Eligible were articles published after 1970, describing outbreaks of more than 10 patients with a nontyphoidal salmonellosis associated with chocolate consumption. RESULTS: Twenty-three articles were included, which described 12 outbreaks involving a total of 3266 patients. All outbreaks occurred in high-income countries: 1 was limited to 1 city, 6 involved 1 country and the remaining 5 involved 2 or more countries. Six outbreaks peaked in winter, 3 in autumn, 2 in spring and 1 in summer. Children were mainly affected. No predominant serotype was identified. CONCLUSIONS: Our data documents that chocolate is an optimal medium for the transmission of nontyphoidal salmonellosis. A connected worldwide reporting system including high-income, middle-income and low-income countries is crucial to detect infectious diseases outbreaks in an early phase and avoid their spread.

RESUMEN

The term Hoigné's syndrome denotes a mimicker of anaphylaxis, which occurs immediately after the parenteral administration of a drug and is likely caused by non-thrombotic pulmonary and systemic drug micro-embolization. It has so far been documented uniquely in case reports and small case series. Because this condition has never been systematically evaluated, we performed a structured literature review (pre-registered as CRD42023392962). The search was carried out in Excerpta Medica, National Library of Medicine, and Google Scholar. Cases with features consistent with anaphylaxis, urticaria, angioedema, asthma, syncope, anxiety, or panic attack triggered by needle phobia, and local anesthetic systemic toxicity were excluded. For the final analysis, we retained reports published between 1951 and 2021, which presented 247 patients with Hoigné's syndrome: 37 children and 211 adults with a male: female ratio of 2.1 : 1.0. The patients presented within 1 min after parenteral administration of a drug (intramuscular penicillin in 90 % of the cases) with chest discomfort, shortness of breath, fear of death, psychomotor agitation, and auditory or visual hallucinations and impairment. Recovery occurred within 30 min. The diagnosis of Hoigné's syndrome was also established in five patients 66-91 years of age with pre-existing cardiovascular or pulmonary diseases, who suddenly died after the administration of penicillin despite not exhibiting the aforementioned symptoms. It was therefore speculated that pulmonary drug micro-embolization induced a lethal cardiovascular compromise in these individuals. Histologic investigations supporting this hypothesis were performed in only one case. The diagnosis of Hoigné's pulmonary drug micro-embolization was established also in five patients with pre-existing cardiovascular or pulmonary diseases, who suddenly died after the administration of penicillin despite not exhibiting the afore mentioned symptoms. Histologic investigations supporting this hypothesis were performed in only one case. In conclusion, Hoigné's syndrome is an uncommon non-immune-mediated reaction. This report seeks to promote broader awareness and knowledge regarding this alarming mimicker of anaphylaxis. Diagnosis relies solely on clinical evaluation.

RESUMEN

The last decade has been characterized by exciting findings on eu- or hypoglycemic ketosis and ketoacidosis. This review emphasizes the following five key points: 1. Since the traditional nitroprusside-glycine dipstick test for urinary ketones is often falsely negative, the blood determination of ß-hydroxybutyrate, the predominant ketone body, is currently advised for a comprehensive assessment of ketone body status; 2. Fasting and infections predispose to relevant ketosis and ketoacidosis especially in newborns, infants, children 7 years or less of age, and pregnant, parturient, or lactating women; 3. Several forms of carbohydrate restriction (typically less than 20% of the daily caloric intake) are employed to induce ketosis. These ketogenic diets have achieved great interest as antiepileptic treatment, in the management of excessive body weight, diabetes mellitus, and in sport training; 4. Intermittent fasting is more and more popular because it might benefit against cardiovascular diseases, cancers, neurologic disorders, and aging; 5. Gliflozins, a new group of oral antidiabetics inhibiting the renal sodium-glucose transporter 2, are an emerging cause of eu- or hypoglycemic ketosis and ketoacidosis. In conclusion, the role of ketone bodies is increasingly recognized in several clinical conditions. In the context of acid-base balance evaluation, it is advisable to routinely integrate both the assessment of lactic acid and ß-hydroxybutyrate.

RESUMEN

INTRODUCTION: Hair-thread strangulation syndrome describes the constriction of a body part by a tightly wound hair or thread. This research aims to review the literature about this entity. METHODS: A systematic review was performed to characterise hair-thread strangulation syndrome in subjects aged ≤16 years. This pre-registered review (PROSPERO ID: CRD42022363996) followed the PRISMA methodology. RESULTS: Subjects with digital strangulation were significantly younger (median = 4.0 [interquartile range: 2.0-6.1] months; n = 143) than females with genital strangulation (9.0 [6.8-11] years; n = 36), males with genital strangulation (5.1 [1.9-8.0] years; n = 36), and subjects with non-digital and non-genital strangulation (24 [13-48] months; n = 11). Digital strangulation was followed by an amputation in five (3.5%) and a reconstructive surgical intervention in seven (4.9%) cases. Sequelae occurred in four (11%) cases after female genital strangulation: clitoris autoamputation (n = 2) and surgical removal of a necrotic labium minus (n = 2). Severe complications were observed in 14 (39%) cases with male genital strangulation: urethral fistula (n = 7), urethral transection (n = 2), and partial penile autoamputation (n = 5). A partial uvular autoamputation was observed in one case (9.0%) with non-digital and non-genital strangulation. CONCLUSIONS: Early recognition and management are crucial to avoid sequelae or long-term care in hair-thread strangulation syndrome.

RESUMEN

Long-term medication with valproic acid has been associated with acute pancreatitis. The purpose of this report is to gain insight into the features of this pancreatitis. A preregistered literature search (CRD42023438294) was performed on the National Library of Medicine, Excerpta Medica, Web of Science, and Google Scholar. Patients with alcohol abuse disorder, gallstone disease, hypertriglyceridemia or hypercalcemia, patients with acute valproic acid intoxication, and patients with a pre-existing pancreatitis were excluded. For the final analysis, we retained 73 reports published between 1979 and 2023, which described 125 subjects (83 children and 42 adults predominantly affected by an epilepsy) with an acute pancreatitis related to valproic acid. The diagnosis was made 11 (3.0-24) months (median and interquartile range) after starting valproic acid. One hundred and five cases (84%) recovered and twenty (16%) died. Sex, age, dosage or circulating level of valproic acid, latency time, prevalence of intellectual disability, and antiepileptic co-medication were similar in cases with and without a lethal outcome. Nineteen subjects were rechallenged with valproic acid after recovery: sixteen (84%) cases developed a further episode of pancreatitis. In conclusion, pancreatitis associated with valproic acid presents at any time during treatment and has a high fatality rate.

RESUMEN

INTRODUCTION: Propofol occasionally induces a green or pink-cloudy urine discoloration. A lesser-known effect is green discoloration of hair, milk, liver, or stool. We aimed to gain insight into the features of these disturbances. METHODS: The terms ("propofol" OR "fospropofol") AND ("green" OR "pink" OR "cloudy" OR "pink-cloudy") were searched in Excerpta Medica, MEDLINE/PubMed®, and Web of Sciences databases, with no language limit, from inception up to February 2023 (CRD4202236804). Articles reporting individually documented cases were retained, and data were extracted using a checklist. RESULTS: Seventy-seven original reports documented 95 cases (including 13 subjects ≤18 years of age). Completeness of reporting was satisfactory in 33, good in 35, and excellent in 27 cases. Propofol-associated green urine discoloration was observed in 54 patients. In most instances (n = 21, 39%), propofol was given for ≥24 h. Sometimes, however, the urine discoloration developed after propofol for ≤3 h (n = 12, 22%). Propofol-associated urine discoloration was usually observed during the administration of this agent, but it was at times (n = 11) first recognized ≥3 h after propofol discontinuation. The duration of green urine discoloration was usually ≤24 h after stopping propofol. Propofol-associated green urine discoloration was never associated with worsening kidney function. A pink-cloudy urine discoloration was observed in 32 subjects with an acidic urine pH and increased uric acid excretion given propofol for ≤24 h. A stage I acute kidney injury was observed in 2 cases (6.3%) of propofol-associated pink-cloudy urine discoloration. Nine cases of non-urinary green discoloration were observed: hair (n = 4), breast milk (n = 1), liver (n = 1), stool (n = 1). CONCLUSION: Propofol is sometimes associated with a green (benign) or pink-cloudy (occasionally associated with mild acute kidney injury) urine discoloration. Rarely, non-urinary green discoloration has been reported.

RESUMEN

Lipschütz genital ulcer is a self-limited, non-sexually acquired disorder characterized by the sudden onset of a few ulcers. A primary Epstein-Barr virus infection is currently considered the most recognized cause. Recent reports document cases temporally related with coronavirus disease 2019 (COVID-19) or immunization against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We carried out a review of the literature to investigate the possible association between COVID-19 or the immunization against SARS-CoV-2 and genital ulcer. The pre-registered study (CRD42023376260) was undertaken following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. Excerpta Medica, the National Library of Medicine, and Web of Sciences were searched. Inclusion criteria encompassed instances of acute Lipschütz ulcer episodes that were temporally linked to either COVID-19 or a vaccination against SARS-CoV-2. Eighteen articles were retained. They provided information on 33 patients 15 (14-24) years of age (median and interquartile range), who experienced a total of 39 episodes of Lipschütz ulcer temporally associated with COVID-19 (N = 18) or an immunization against SARS-CoV-2 (N = 21). The possible concomitant existence of an acute Epstein-Barr virus infection was excluded in 30 of the 39 episodes. The clinical presentation and the disease duration were similar in episodes temporally associated with COVID-19 and in those associated with an immunization against SARS-CoV-2. In conclusion, COVID-19 and immunization against SARS-CoV-2 add to Epstein-Barr virus as plausible triggers of Lipschütz genital ulcer.

RESUMEN

BACKGROUND: Epstein-Barr virus (EBV), also known as human herpesvirus 4, is one of the most common pathogenic viruses in humans. EBV mononucleosis always involves the spleen and as such it predisposes to splenic rupture, often without a trauma, and splenic infarction. Nowadays the goal of management is to preserve the spleen, thereby eliminating the risk of post-splenectomy infections. METHODS: To characterise these complications and their management, we performed a systematic review (PROSPERO CRD42022370268) following PRISMA guidelines in three databases: Excerpta Medica, the United States National Library of Medicine, and Web of Science. Articles listed in Google Scholar were also considered. Eligible articles were those describing splenic rupture or infarction in subjects with Epstein-Barr virus mononucleosis. RESULTS: In the literature, we found 171 articles published since 1970, documenting 186 cases with splenic rupture and 29 with infarction. Both conditions predominantly occurred in males, 60% and 70% respectively. Splenic rupture was preceded by a trauma in 17 (9.1%) cases. Approximately 80% (n = 139) of cases occurred within three weeks of the onset of mononucleosis symptoms. A correlation was found between the World Society of Emergency Surgery splenic rupture score, which was retrospectively calculated, and surgical management: splenectomy in 84% (n = 44) of cases with a severe score and in 58% (n = 70) of cases with a moderate or minor score (p = 0.001). The mortality rate of splenic rupture was 4.8% (n = 9). In splenic infarction, an underlying haematological condition was observed in 21% (n = 6) of cases. The treatment of splenic infarction was always conservative without any fatal outcomes. CONCLUSIONS: Similarly to traumatic splenic rupture, splenic preservation is increasingly common in the management of mononucleosis-associated cases as well. This complication is still occasionally fatal. Splenic infarction often occurs in subjects with a pre-existing haematological condition.

RESUMEN

BACKGROUND: Unfounded concerns regarding fever are increasingly observed among nurses worldwide. However, no study has so far explored the preferred approach towards pediatric fever among nursing students. Therefore, we aimed to investigate the attitude towards pediatric fever among final-year nursing students. METHODS: Between February and June 2022, final-year nursing students of 5 Italian university hospitals were asked to answer an online survey on their approach to fever in children. Both quantitative and qualitative methods were utilized. Multiple regression models were employed to explore the existence of moderators on fever conceptions. RESULTS: The survey was filled in by 121 nursing students (response rate 50%). Although most students (98%) do not consider discomfort to treat fever in children, only a minority would administer a second dose of the same antipyretic in nonresponsive cases (5.8%) or would alternate antipyretic drugs (13%). Most students would use physical methods to decrease fever (84%) and do not think that fever has mainly beneficial effects in children (72%). The own know-how adequacy on fever was inversely associated (OR 0.33, 95% CI 0.13-0.81) with the beliefs that high fever might lead to brain damage. No further predictive variable was significantly associated with the concern that fever might be associated with brain damage, the advice of physical methods use, and the assumption that fever has mostly positive effects. DISCUSSION: This study shows for the first time that misconceptions and inappropriate attitudes towards fever in children are common among final-year nursing students. Nursing students could potentially be ideal candidates for improving fever management within clinical practice and amongst caregivers.

RESUMEN

Finkelstein-Seidlmayer vasculitis, also called acute hemorrhagic edema of young children or infantile immunoglobulin A vasculitis, is habitually a benign skin-limited small vessel leukocytoclastic vasculitis that mainly affects infants 24 months or less of age. Since this disease is commonly triggered by an infection, an immune-mediated origin has been postulated. To better appreciate the possible underlying immune mechanism of this vasculitis, we addressed circulating autoimmune markers and vascular immune deposits in patients contained in the Acute Hemorrhagic Edema BIbliographic Database, which incorporates all original reports on Finkelstein-Seidlmayer vasculitis. A test for at least one circulating autoimmune marker or a vascular immune deposit was performed in 243 cases. Subunits of complement system C4 resulted pathologically reduced in 4.7% and C3 in 1.4%, rheumatoid factor was detected in 6.1%, and antinuclear antibodies in 1.9% of cases. Antineutrophil cytoplasmic antibodies were never demonstrated. Immunofluorescence studies were performed on 125 skin biopsy specimens and resulted positive for complement subunits in 46%, fibrinogen in 45%, immunoglobulin A in 25%, immunoglobulin M in 24%, immunoglobulin G in 13%, and immunoglobulin E in 4.2% of cases. Infants testing positive for vascular immunoglobulin A deposits did not present a higher prevalence of systemic involvement or recurrences, nor a longer disease duration. In conclusion, we detected a very low prevalence of circulating autoimmune marker positivity in Finkelstein-Seidlmayer patients. Available immunofluorescence data support the notion that immune factors play a relevant role in this vasculitis. Furthermore, vascular immunoglobulin A deposits seem not to play a crucial role in this disease.

RESUMEN

BACKGROUND: Valproic acid is prescribed for epilepsy and as prophylaxis for bipolar disorder and migraine headaches. It has also been implicated as a cause of a kidney tubular injury. METHODS: We undertook a review of the literature to characterize the biochemical and histopathological features of the overt kidney tubular injury and to evaluate the possible existence of a pauci-symptomatic injury. The pre-registered review (CRD42022360357) was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Searches were conducted in Excerpta Medica, the National Library of Medicine, and Web of Science. The gray literature was also considered. RESULTS: For the final analysis, we retained 36 articles: 28 case reports documented 48 individuals with epilepsy on valproic acid for 7 months or more and presenting with features consistent with an overt kidney tubular injury. The following disturbances were noted: hypophosphatemia (N = 46), normoglycemic glycosuria (N = 46), total proteinuria (N = 45), metabolic acidosis (N = 36), hypouricemia (N = 27), tubular proteinuria (N = 27), hypokalemia (N = 23), and hypocalcemia (N = 8). A biopsy, obtained in six cases, disclosed altered proximal tubular cells with giant and dysmorphic mitochondria. Eight case series addressed the existence of a pauci- or even asymptomatic kidney injury. In the reported 285 subjects on valproic acid for 7 months or more, an isolated tubular proteinuria, mostly N-acetyl-ß-glucosaminidase, was often noted. CONCLUSIONS: Valproic acid may induce an overt kidney tubular injury, which is associated with a proximal tubular mitochondrial toxicity. Treatment for 7 months or more is often associated with a pauci- or oligosymptomatic kidney tubular injury. A higher resolution version of the Graphical abstract is available as Supplementary information.

RESUMEN

Multivitamins are commonly used by the general population, often without medical prescription. The purpose of this report is to inform on the daily vitamin D supply provided by multivitamins containing vitamin D that are commercialized online by Amazon in Western and Southern Europe. We surveyed multivitamins aimed at adults using the following marketplaces: amazon.es®, amazon.de®, amazon.it®, and amazon.fr®. We identified 199 vitamin D3-containing multivitamins sold by Amazon marketplaces: 77 from amazon.es®, 73 from amazon.de®, 33 from amazon.it®, and 16 from amazon.fr®. No multivitamin contained vitamin D2. The daily vitamin D3 supply ranged from 16 to 2000 IU: it was less than 400 IU daily in 108 (54%), 400−800 IU daily in 53 (27%), and more than 800 IU daily in the remaining 38 (19%) products. The vitamin D3 supply of products sold by amazon.it® was on average higher (p < 0.05) than that of products sold by amazon.de®, amazon.fr®, and amazon.es®. In conclusion, the vitamin D supply of multivitamins sold by Amazon may be insufficient, marginally sufficient, or adequate for subjects at high risk of hypovitaminosis D such as subjects 65 years or more of age, pregnant (or lactating) women, or patients on drug treatment or with an underlying disease, where a vitamin D supplementation is advocated.

RESUMEN

Despite the availability of clinical guidelines on the correct symptomatic management of fever in children, several studies have reported inaccurate knowledge about this symptom and inappropriate management behaviours among caregivers. There is evidence that caregivers' management of fever is largely influenced by unrealistic and unwarranted concerns about the potential harm that elevated body temperature can cause, a phenomenon commonly referred to as fever phobia. Research on fever phobia has predominantly focused on the role of fever misconceptions in triggering anxiety and impeding a proper fever management, in terms of both concept and operationalization, with little attention to the influence of the relationship between caregivers and the healthcare team. The aim of this pilot study was to explore and describe fever-related knowledge, experience and behaviour among a sample of caregivers, paediatricians and their medical assistants in the Canton of Ticino, Switzerland. We used a qualitative study design with semi-structured, one-to-one interviews with paediatricians employed in private healthcare facilities, their medical assistants and caregivers with at least one child between the ages of 0 and 3 years. We conducted individual interviews either in person or by phone, according to participants' preferences, between October 2020 and February 2021. We performed an inductive-deductive analysis of the transcripts to identify the most meaningful themes from participants' reports. The analysis of the transcripts yielded three main themes. The first theme refers to participants' awareness of the emotional component in managing the child's fever and the challenges this component presents. The second theme refers to the risk of overtreating when the child's right to be sick is not recognized and respected. The third theme refers to the importance of the relational component, showing how a solid therapeutic alliance with the healthcare team helps caregivers develop self-confidence in managing the child's fever. This study contributes to advance our understanding of fever phobia and to a better conceptualization and operationalization of this phenomenon. CONCLUSION: Our results point out to the importance of going beyond a knowledge gap paradigm and recognizing both the emotional and the relational component of fever phobia, the former being entrenched in latter, that is, the unique relationship caregivers establish with their child's paediatrician and the medical assistant. WHAT IS KNOWN: • Research on fever phobia has predominantly focused on the role of fever misconceptions in triggering anxiety and impeding a proper fever management, in terms of both concept and operationalization, with little attention to the relational component of this phenomenon. WHAT IS NEW: • Our results point out to the importance of recognizing the emotional component of fever phobia, beyond its declarative and procedural knowledge dimensions. They also suggest that overtreating is not necessarily and not only the result of a phobia but also of a particular conception of health and the relational component of this phenomenon, which is entrenched in the unique relationship caregivers establish with their child's paediatrician and the medical assistant.

RESUMEN

BACKGROUND: The typical presentation of Epstein-Barr virus infectious mononucleosis includes fever, pharyngitis, measles-like rash, jaundice, and enlarged lymph nodes, liver, or spleen. A painless bilateral swelling of the upper eyelid, sometimes with drooping of the lateral aspect, may also occur. This sign, referred to as Hoagland sign, is not or only marginally mentioned in reviews and textbooks. METHODS: Between 2019 and 2021, two of us evaluated all subjects with a positive acute Epstein-Barr virus serology for the typical signs of mononucleosis and for the possible existence of the Hoagland sign. RESULTS: During the mentioned period, the diagnosis of mononucleosis was made in 26 (14 females and 12 males) subjects aged from 9.0 to 33 years. The initial presentation included fever in 24, enlarged cervical lymph nodes in 23, pharyngitis in 21, a palpable liver in 7, a palpable spleen in 7, jaundice in 2, and a measles-like rash in 2 cases. The Hoagland sign was noted in 14 cases. Patients with and without Hoagland sign did not significantly differ with respect to age and sex. CONCLUSIONS: The Hoagland sign is an easily identifiable clinical sign that is common and likely helpful early in the course of Epstein-Barr virus infectious mononucleosis. There is a need to expand awareness of this sign among physicians.

RESUMEN

AIMS: Undue concerns about the consequences of fever and its inappropriate management have been documented worldwide among physicians. However, no data exist on medical students. We investigated the perception, knowledge and attitude towards childhood fever among final-year medical students. METHODS: Between June and September 2021, final-year medical students of six Italian universities were invited to complete an online survey on their conceptions and attitude towards pharmacological and non-pharmacological management of childhood fever. History of relevant personal or second-hand experience with childhood fever was also addressed. Both quantitative and qualitative approaches were used. RESULTS: Of 1095 (69%) final-year medical students, 756 completed the survey. Many students believe that high fever might cause brain damage, would recommend physical methods and alternate two drugs for fever. Most students do not think that fever has mainly beneficial effects. In Northern Italy, students are less likely to believe that fever might lead to brain damage (OR 0.55, 95% CI 0.33-0.94), and in Southern Italy students are more likely to advise physical methods (OR 1.77, 95% CI 1.22-2.57) and less likely to believe that fever has mainly beneficial effects (OR 0.55, 95% CI 0.39-0.77). History of a relevant personal episode of fever during childhood was not associated with these outcomes. CONCLUSIONS: Misconceptions about fever are common among final-year medical students in Italy. Cultural factors rather than individually learned traits might underlie these beliefs. Medical students are a promising target for educational interventions to improve childhood fever management.

RESUMEN

BACKGROUND: Extra-pulmonary features sometimes occur in association with atypical bacterial pneumonia and include neurologic manifestations, diarrhea, rashes, altered liver enzymes, or kidney injury, among other conditions. Acute pancreatitis has been associated with atypical pneumonias since 1973. METHODS: We performed a systematic review of the literature in the Excerpta Medica, National Library of Medicine, and Web of Science databases. We retained 27 reports published between 1973 and 2022 describing subjects with an otherwise unexplained pancreatitis temporally associated with an atypical pneumonia. RESULTS: The reports included 33 subjects (19 males, and 14 females; 8 children and 25 adults) with acute pancreatitis temporally associated with atypical pneumonia caused by Mycoplasma pneumoniae (n = 18), Legionella species (n = 14), or Coxiella burnetii (n = 1). Approximately 90% of patients (n = 29) concurrently presented with respiratory and pancreatic diseases. No cases associated with Chlamydophila pneumoniae, Chlamydophila psittaci, or Francisella species were found. CONCLUSIONS: Acute pancreatitis has been associated with various infectious agents. The present review documents the association with atypical pneumonia induced by Mycoplasma pneumoniae, Legionella species, and Coxiella burnetii.
