Although considerable progress in tumor diagnostics and targeted therapies has been made over the past 2 decades, recommendations and controversies relating to tumor imaging and margins of resection have not changed.

Limb lengthening with magnetically driven intramedullary lengthening nails is a fast-developing field and represents an alternative to external fixators. Although previous studies have assessed the application of magnetically driven intramedullary lengthening nails, these studies have been heterogenous regarding the nailing approach, the bone treated, and the implant type; they also have analyzed relatively small patient groups at short follow-up durations.

(1) Is femoral lengthening with magnetically driven antegrade intramedullary lengthening nails accurate and precise? (2) What are the most common complications of treatment? (3) What factors are associated with unplanned additional surgery?

We retrospectively analyzed the longitudinally maintained database of our orthopaedic teaching hospital to identify all patients who underwent surgery for leg length discrepancy (LLD) between October 2014 and April 2019. In total, we surgically treated 323 patients for LLD of 2 cm or more. Of those 55% (177 of 323iven antegrade intramedullary lengthening nails appears to be an accurate and reliable treatment for femoral lengthening. However, depending on the etiology, a high risk of unplanned additional surgery should be anticipated, and a high proportion of patients will experience temporary joint stiffness. We recommend close orthopaedic follow-up and physiotherapy during treatment. This treatment of LLD can be considered alongside other nails, external fixators, and epiphysiodesis. Multicenter studies comparing this with other approaches are needed.

Level IV, therapeutic study.

Level IV, therapeutic study.Orthopaedic surgery is the least diverse of all medical specialties, by both sex and race. Diversity among orthopaedic trainees is the lowest in medicine, and growth in percentage representation is the lowest of all surgical subspecialties. Women comprise only 6% of orthopaedic surgeons and 16% of orthopaedic surgery trainees. This extreme lack of diversity in orthopaedics limits creative problem-solving and the potential of our profession. Women in orthopaedics encounter sexual harassment, overt discrimination, and implicit bias, which create barriers to training, career satisfaction, and success. Women are underrepresented in leadership positions, perpetuating the lack of diversity through poor visibility to potential candidates, which impedes recruitment. Correction will require a concerted effort, as acknowledged by the American Academy of Orthopaedic Surgeons leadership who included a goal and plan to increase diversity in the 2019 to 2023 Strategic Plan. Recommended initiatives include support for pipeline programs that increase diversity of the candidate pool; sexual harassment and implicit bias acknowledgement, education, and corrective action; and the active sponsorship of qualified, capable women by organizational leaders. To follow, women will lend insight from their diverse viewpoints to research questions, practice problems, and clinical conundrums of our specialty, augmenting the profession and improving patient outcomes.

Bone marrow edema (BME) is a nonspecific but relevant finding, usually indicating the presence of an underlying pathology.

The gold standard technique for detecting BME is magnetic resonance imaging (MRI), as it allows for a correct diagnosis to be made, which is extremely important given the heterogeneity of BME-related diseases.

Depending on the severity of painful symptomatology and the MRI evidence, different treatment strategies can be followed physical modalities, pharmacological options, and surgical therapy.

Founded in 1999, The Forum was conceived as a partnership with women in industry, designed to support women orthopaedic surgeons by providing a place to share research and practice ideas and to stimulate interest and research in arthroscopic surgery. Membership has grown from a handful of founding members to nearly 100 strong in 2021. An annual meeting is held over Martin Luther King, Jr., weekend each year, combining scientific and social programs and highlighted by the Sandy Kirkley Memorial Lecture. The Forum has recently gained notoriety through the work of some of its members in advocating for the protection of athletes from sexual abuse and the publication of the first position statement on the topic, subsequently endorsed by the American Academy of Orthopaedic Surgeons. A recent partnership with the American Orthopaedic Society for Sports Medicine and the Arthroscopy Association of North America to provide concurrent sessions at the 2021 combined annual meeting has increased the visibility of the society and its members.

Human T-lymphotropic virus (HTLV) 1 and 2 infections can lead to neurological diseases, mainly in HIV/HTLV 1 coinfected. Furthermore, HTLV 1 infection in HIV/AIDS patients has also been associated with AIDS progression. Despite this, HTLV 1/2 infections are not of mandatory notification in Brazil. Here, we describe the prevalence of HTLV 1/2 in HIV/AIDS patients from Paraíba state, Brazil, as well as the sociodemographic characteristics of the coinfected individuals.

Information about HIV viral load and TCD4 lymphocyte count were obtained from patients’ records. Data on the patients’ sociodemographic characteristics were obtained by interview conducted after signing the informed consent form. The serological diagnosis for HTLV 1/2 was performed by Enzyme-Linked Immunosorbent Assay (ELISA) and Western Blot (WB).

A total of 401 HIV/AIDS patients participated in the study, of whom about 1.5% (6/401) were positive for antibodies against HTLV, specifically for HTLV 1, evaluated by both ELISA and WB. No risk factors were found associated with HIV/HTLV 1/2 coinfection.

We report a 1.5% prevalence of HTLV 1 infection in HIV/AIDS patients from Paraíba state. Although we have not identified risk factors associated with HTLV 1, we describe the most observed sociodemographic characteristics in HIV/HTLV 1 coinfection.

Sexually transmitted infections are among the most frequent infections affecting pregnant women. We assessed the transmission of hepatitis B virus, human immunodeficiency virus type 1 and Treponema pallidum to newborns from infected parturients.

An observational, cross-sectional, analytical facility-based survey was conducted among 57 newborns in Irene Neto Maternity, Lubango city, Huíla province, Angola. Hepatitis B virus DNA molecular identification was done through nested PCR. Human immunodeficiency virus type 1 proviral DNA detection was carried out by two successive nested PCRs. Real-time PCR was performed to examine the presence of T. pallidum DNA. Amplicons from PCR positive samples were sequenced for identity search and genotype assignment.

Hepatitis B virus DNA genotype E was detected in 3/41 (7.3%) newborns from HBsAg (hepatitis B surface antigen) positive mothers. To analyse the association between mothers HBeAg (hepatitis B e antigen) positivity and hepatitis B virus vertical transmission to newborns, a Fisher’s exact test was performed, showing a highly significant association (p = 0.006). Human immunodeficiency virus type 1 provirus or T. pallidum DNA was not detected in any newborn.

To prevent hepatitis B virus vertical transmission in Angola it is important to promote universal antenatal screening, expanding hepatitis B virus markers (viral load and/or HBeAg), risk-based infected mothers’ antiviral therapy and newborn passive immunoprophylaxis.

The protozoan parasite Cryptosporidium is one of the principal reasons for childhood diarrhea around the world. This work aimed to differentiate Cryptosporidium species among children suffering from diarrhea in Sharkyia Governorate, Egypt.

A total of 97 fecal specimens were taken from children suffering from diarrhea, attending Pediatric Clinics of Zagazig University and Al-Ahrar Hospitals. Full history was taken. Stool samples were examined microscopically using modified Ziehl-Neelsen stain for detection of Cryptosporidium oocysts. To identify Cryptosporidium genotypes, positive samples were then subjected to nested Polymerase chain reaction-restriction fragment length polymorphism targeting Cryptosporidium oocyst wall protein gene.

The overall detection rate was 27.8% (27/97) using modified Ziehl-Neelsen stain staining method. Using nested polymerase chain reaction, the gene was amplified in 85.2% (23/27). Restriction fragment length polymorphism analysis revealed that 65.2% (15/23) were Cryptosporidium hominis, 30.4% (7/23) were Cryptosporidium parvum, and one sample was not typed (4.4%). The significant risk factors associated with Cryptosporidium infection in children were animal contact and residence in rural areas.

Cryptosporidium is a common enteric parasite affecting children in Sharkyia Governorate, Egypt, with the predominance of C. hominis genotype in children.

Although Cysticercus tenuicollis is one of the most economic and veterinary important parasite in Iraq, scanty molecular characterization exists for this helminth. This study aimed to determine the prevalence and molecular description of C. tenuicollis isolates from sheep in Kalar district of Iraq.

A total of 2,906 slaughtered sheep were examined post-mortem. Up to 20 samples of C. tenuicollis was extracted and amplified using mitochondrial COX1 gene.

The overall prevalence rate was 6.88%, and female sheep recorded higher rate of infection (24.35%) than male (6.16%) with significant difference (p<0.05). The molecular results showed 14 haplotypes for COX1 gene and the pairwise nucleotide variation among them was ranged from 0.2 to 2.6%. Twelve out of fourteen haplotypes of C. tenuicollis involving one to three base mutations were discovered in Kalar, Iraq for the first time and this could be a unique mutation internationally and did not registered previously. Eleven newly recorded haplotypes involved ograms.

This cross-sectional study evaluated the impact of socioeconomic status on the knowledge, attitudes, and practices (KAP) concerning zoonotic visceral leishmaniasis (VL) among dog owners from the municipality of Rondonópolis-a highly endemic area for the disease in Central-Western Brazil.

Data were collected between 2016 and 2017 during a household survey. click here A probabilistic sample of 404 dog owners were interviewed assessing sociodemographic characteristics, previous occurrence of VL cases, and KAP about human VL, vector, and canine VL. Responses regarding KAP were compared among social classes, which are indicators of socioeconomic status. Correct/appropriate answers were scored, and a multivariate Poisson regression analysis evaluated the impact of social class on scoring.

The overall KAP regarding VL was limited. Dog owners from higher social classes differed from those of the lower classes regarding the recognition of abdominal distension (p = 0.026) and skin lesions (p < 0.001) as clinical manifestations of human and canine VL, respectively, knowledge of VL transmission (p = 0.
