Kikuchi-Fujimoto Disease: A Case Series and Review of the Literature.

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare, self-limiting disorder characterized by fever typically lasting for 1 week up to 1 month and painful necrotizing lymphadenopathy, primarily affecting young adults of Asian ancestry. Although the exact cause remains unclear, infectious and autoimmune mechanisms have been implicated in the pathogenesis of the disease. In this case series, we aim to describe the histopathological features of KFD over a ten-year period at Mount Sinai Medical Center of Florida, and review the current understanding of its pathogenesis, clinical presentation, diagnosis, and management.

Monkeypox Proctitis: A Case of Targeted Treatment With Tecovirimat.

Monkeypox (MPX) is an exanthematous disease first identified in the 1950s, associated with animals in Central and Western Africa, and has since been found sporadically worldwide. In May 2022, a returning family from Nigeria tested positive for MPX, which marked the onset of the current outbreak.It has now become a disease of concern in most parts of the world.

: An emerging pathogen in culture negative bacterial prosthetic valve infective endocarditis (IE).

(previously known as ) infections are reportedly increasing in patients with implanted foreign material. Though it is a rare cause of bacterial endocarditis, patients with implanted prosthetic valves and devices have potential increased risk. Cutibacterium species are an ubiquitous environmental surface contaminant and typically difficult to culture, in case of high suspicion for infective endocarditis extended duration incubation of blood or any tissue sample and 16S RNA sequencing of any tissue sample is helpful for a microbiological identification.

Effectiveness of maternal pertussis vaccination in protecting newborn: A matched case-control study.

Introduction: The objective was to estimate the effectiveness of maternal pertussis vaccination in protecting infants aged < 2 months.

Methods: We performed a case-control study. Laboratory-confirmed cases aged <8 weeks at disease onset were identified and 2-4 matched-controls born within ± 15 days of the case were included.

Azithromycin to Prevent Pertussis in Household Contacts, Catalonia and Navarre, Spain, 2012-2013.

We retrospectively assessed the effectiveness of azithromycin in preventing transmission of pertussis to a patient's household contacts. We also considered the duration between symptom onset in the primary patient and azithromycin administration. We categorized contacts into 4 groups: those treated within <7 days, 8-14 days, 15-21 days, and >21 days after illness onset in the primary patient.

A case of respiratory toxigenic diphtheria: contact tracing results and considerations following a 30-year disease-free interval, Catalonia, Spain, 2015.

In May 2015, following a 30-year diphtheria-free interval in Catalonia, an unvaccinated 6-year-old child was diagnosed with diphtheria caused by toxigenic . After a difficult search for equine-derived diphtheria antitoxin (DAT), the child received the DAT 4 days later but died at the end of June. Two hundred and seventeen contacts were identified in relation to the index case, and their vaccination statuses were analysed, updated and completed.

Trends and risk factors of hepatitis A in Catalonia after the introduction of a hepatitis A+B vaccination programme.

At the end of 1998, universal hepatitis A+B vaccination of 12 year olds was introduced in Catalonia. The aim was to examine trends in hepatitis A during 2005-2015 and assess risk factors by age group. We carried out an observational epidemiological study of the incidence and risk factors of hepatitis A reported to the surveillance system.

Psychological distress in patients undergoing surgery for urological cancer: A single centre cross-sectional study.

Purpose: Interest in the disease-specific psychological well-being of patients with cancer has increased, and it has been estimated that less than half of all patients with cancer are properly identified and subsequently treated for anxiety or depression. The aim of this study is to evaluate psychological distress in uro-oncological patients undergoing different surgeries: radical cystectomy, radical prostatectomy, radical nephrectomy, or transurethral resection (TUR) before the surgery.

Materials And Methods: We performed a cross-sectional study in consecutively enrolled patients with bladder, kidney, or prostate cancer, scheduled for surgery.

Assessment of clinical symptoms in household contacts of confirmed pertussis cases.

Objectives: We assessed the value of the clinical symptoms included in the case definition of pertussis in household contacts of laboratory-confirmed cases.

Methods: A prospective epidemiological study was made in two Spanish regions. Household contacts were identified for each confirmed case reported during 2012 and 2013.

Modulation of SHBG binding to testosterone and estradiol by sex and morbid obesity.

Objective: Sex hormone-binding globulin (SHBG) binds and transports testosterone and estradiol in plasma. The possibility that SHBG is a mixture of transporting proteins has been postulated. We analyzed in parallel the effects of obesity status on the levels and binding capacity of circulating SHBG and their relationship with testosterone and estradiol.

Factors influencing the spread of pertussis in households: a prospective study, Catalonia and Navarre, Spain, 2012 to 2013.

We aimed to investigate transmission rates of pertussis in household contacts of cases and factors associated with transmission. A prospective epidemiological study was conducted in 2012 and 2013 to determine the incidence of pertussis among household contacts of reported cases in Catalonia and Navarre, Spain. An epidemiological survey was completed for each case and contact, who were followed for 28 days to determine the source of infection (primary case) and detect the occurrence of secondary cases.

Effectiveness of acellular pertussis vaccination during childhood (<7 years of age) for preventing pertussis in household contacts 1-9 years old in Catalonia and Navarra (Spain).

Pertussis vaccination with 4-5 doses of acellular vaccines is recommended in Spain to all children at 2 months to 6 years of age. The effectiveness of the acellular pertussis vaccination was assessed in this study by comparing the incidence of secondary pertussis in vaccinated (4-5 doses) and unvaccinated or partially vaccinated (0-3 doses) household contacts 1-9 years old of confirmed cases of pertussis in Spain in 2012-13. Eighty-five percent of contacts had been vaccinated with 4-5 doses of acellular pertussis vaccines.

Epidemiology of Acute Gastroenteritis Outbreaks Caused by Human Calicivirus (Norovirus and Sapovirus) in Catalonia: A Two Year Prospective Study, 2010-2011.

Background: The epidemiology of cases of acute gastroenteritis (AGE) of viral etiology is a relevant public health issue. Due to underreporting, the study of outbreaks is an accepted approach to investigate their epidemiology. The objective of this study was to investigate the epidemiological characteristics of AGE outbreaks due to norovirus (NoV) and sapovirus (SV) in Catalonia.

Importance of Enhanced Surveillance for Prevention of Pertussis in Children.

Background: Bordetella pertussis infection causes considerable morbidity, even in countries with high vaccination coverage. Surveillance of pertussis is usually passive and based on mandatory reporting. We assessed the epidemiologic and clinical characteristics of pertussis cases detected by passive or enhanced surveillance.

Pandemic A/H1N1 influenza: transmission of the first cases in Spain.

Introduction: Pandemic A/H1N1 influenza emerged in Mexico at the end of March 2009. Since then, it is still important to provide evidences that contributed to the international spread of the virus and to ascertain the attack rate of this new strain of influenza among the first cases in Spain that led to identify the first transmission in Europe.
