ABSTRACT

BACKGROUND: Cervical cancer is a rare primary tumor resulting in metastases to the breast with few cases reported in literature. Breast metastases are associated with poor prognosis. The following case highlights the diagnostic challenges associated with metastatic cervical cancer to the breast along with individualized treatment. CASE SUMMARY: A 44-year-old G7P5025 with no significant past medical or surgical history presented with heavy vaginal to an outside emergency department where an exam and a pelvic magnetic resonance imaging showed a 4.5 cm heterogenous lobulated cervical mass involving upper two thirds of vagina, parametria and lymph node metastases. Cervical biopsies confirmed high grade adenocarcinoma with mucinous features. A positron emission tomography/computed tomography (PET/CT) did not show evidence of metastatic disease. She received concurrent cisplatin with external beam radiation therapy. Follow up PET/CT scan three months later showed no suspicious fluorodeoxyglucose uptake in the cervix and no evidence of metastatic disease. Patient was lost to follow up for six months. She was re-imaged on re-presentation and found to have widely metastatic disease including breast disease. Breast biopsy confirmed programmed death-ligand 1 positive metastatic cervical cancer. The patient received six cycles of carboplatin and paclitaxel with pembrolizumab. Restaging imaging demonstrated response. Patient continued on pembrolizumab with disease control. CONCLUSION: Metastatic cervical cancer to the breast is uncommon with nonspecific clinical findings that can make diagnosis challenging. Clinical history and immunohistochemical evaluation of breast lesion, and comparison to primary tumor can support diagnosis of metastatic cervical cancer to the breast. Overall, the prognosis is poor, but immunotherapy can be considered in select patients and may result in good disease response.

ABSTRACT

Strongyloidiasis is a parasitic infection with a high global burden of disease. Hyperinfection syndrome is a life-threatening complication that predominantly affects immunosuppressed individuals, such as those receiving corticosteroid treatment. Despite its worldwide prevalence, little is known about the clinical effects of this condition on the feto-maternal dyad during pregnancy. We present a case of placental abruption leading to preterm delivery in a pregnancy complicated by Strongyloides stercoralis hyperinfection syndrome following antenatal corticosteroid use. Although rare, this condition is associated with high mortality rates and adverse pregnancy outcomes. Therefore, screening at-risk individuals may be warranted in pregnancies where antenatal corticosteroid administration is considered.

ABSTRACT

OBJECTIVE: Cystic fibrosis (CF) is a genetic condition that causes abnormal mucus secretions in affected organs. MUC5AC and MUC5B are gel-forming mucins and frequent targets for investigations in CF tissues. Our objective was to qualify MUC5AC and MUC5B immunohistochemical techniques to provide a useful tool to identify, localize and interpret mucin expression in ferret tissues. RESULTS: MUC5AC and MUC5B mucins were detected most commonly in large airways and least in small airways, consistent with reported goblet cell density in airway surface epithelia. We evaluated whether staining method affected the detection of goblet cell mucins in serial sections of bronchial surface epithelia. Significant differences between stains were not observed suggesting common co-expression MUC5AC and MUC5B proteins in goblet cells of airway surface epithelia. Gallbladder and stomach tissues are reported to have differential mucin enrichment, so we tested these tissues in wildtype ferrets. Stomach tissues were enriched in MUC5AC and gallbladder tissues enriched in MUC5B, mucin enrichment similar to human tissues. Mucin immunostaining techniques were further qualified for specificity using lung tissue from recently generated MUC5AC-/- and MUC5B-/- ferrets. Qualified techniques for MUC5AC and MUC5B immunohistochemistry will be useful tools for mucin tissue studies in CF and other ferret models.

ABSTRACT

Objective: To report two cases of oocyte retrieval performed in asymptomatic SARS-CoV-2-positive patients. Design: Case report. Setting. Outpatient private practice infertility center. Patients. A 28-year-old woman at risk for OHSS who took her trigger injection prior to testing positive for SARS-CoV-2 and a 19-year-old oncofertility patient who tested positive prior to retrieval due to a family exposure. Both patients were asymptomatic. Main Outcome Measures. Cycle outcomes, patient safety, and staff safety. Results: Both patients underwent successful oocyte retrieval procedures without developing symptoms or complications from COVID-19. No staff members that cared for these patients developed symptoms of COVID-19. Conclusion: Worsening fertility outcomes and potential for psychological and financial burdens to the patient must be balanced with risk of perioperative complications in patients testing positive for SARS-CoV-2. As we continue to provide fertility care in a world with COVID-19, appropriate risk mitigation strategies should be implemented to minimize exposure to SARS-CoV-2.

ABSTRACT

OBJECTIVE: Inflammation is present in many diseases and identification of immune cell infiltration is a common assessment. CD138 (syndecan-1) is a recommended immunohistochemical marker for human plasmacytes although it is also expressed in various epithelia and tumors. Similarly, CD138 is a marker for murine plasmacytes, but its tissue immunostaining is not well-defined. Endogenous CD138 expression is an important confounding factor when evaluating plasmacyte infiltration. We studied two plasmacyte markers (CD138 and Kappa light chains) for endogenous immunostaining in five organs and one tumor from B6 mice. RESULTS: Plasmacytes in Peyer's patches were positive for CD138 and Kappa markers without endogenous immunostaining. Endogenous CD138 immunostaining was widespread in liver, kidney, lung and a malignant peripheral nerve sheath tumor (MPNST) versus regionalized immunostaining in skin and small intestine wall. Endogenous Kappa immunostaining was absent in all tissues except for plasmacytes. Tissues with widespread endogenous CD138 immunostaining were contrasted by absence of endogenous Kappa immunostaining. Here, plasmacytes would not be distinguished by CD138, but would be obvious by Kappa immunostaining. Our study suggests that utility of immunostaining for plasmacytes by CD138 is tissue dependent in mice. Additionally, Kappa immunostaining may be a useful alternative in mouse tissues with confounding endogenous CD138 immunostaining.

ABSTRACT

Because of their increased mobility, lack of resistance to hoop stresses, and decreased blood supply, radial tears of the lateral meniscus are more troublesome to heal than vertical longitudinal tears. Given the success of meniscal root repairs, radial tears of the lateral meniscal body should be given strong consideration for repair because of a more reproducible ability to heal such lesions in young, active patients. Technique options that should be considered for the less common anterior radial tears of the lateral meniscus include outside-in repair, self-capturing suture-passing devices, and orthobiologic treatments to stimulate healing. Although a variety of suture techniques, including the double horizontal mattress and horizontal butterfly patterns, have demonstrated improvements in patient outcomes, evidence is still limited with regard to the ideal suture pattern for radial tears.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has caused significant disruption to undergraduate medical education (UME). Although the immediate scheduling challenges are being addressed, there has been less discourse regarding how this pandemic will impact medical students in their preparation for and application to residency programs. While some historical disasters and pandemics provide a loose precedent for UME response during COVID-19, the impact of the current pandemic has surpassed any other events. COVID-19 will likely impact UME in the suspension of clinical rotations, alterations in grading, suspension or elimination of away rotations, changes in medical licensing exams, and ramifications on mental health. This review assesses governing medical bodies' recommendations regarding UME during the COVID-19 pandemic and how this may impact preparation for residency. In particular, residency programs will likely have to create new guidelines for assessing applicants during this unique cycle.

ABSTRACT

BACKGROUND AND AIM: Botulinum toxin (botox) is a commonly used treatment for functional anorectal and colonic disorders. Although generally regarded as safe, complications associated with botox injection into the anal sphincters in children with severe defecation disorders are not well described. We aimed to review our institutional experience and the existing literature to better understand the safety of this practice. METHODS: We performed a retrospective review of pediatric patients undergoing botox administration into the anal sphincter for treatment of a variety of defecation disorders between 2014 and 2018. Additionally, we performed a review of all published literature reporting complications from botox injection in this patient population. RESULTS: 881 patients ranging from 5 weeks to 19.7 years underwent a total of 1332 botox injections including our institution (332 patients/526 injections) and the reviewed series (549 patients/806 injections). Overall, complications were seen after 9 (0.7%) injections and included urinary incontinence (n = 5), pelvic muscle paresis (n = 2), perianal abscess (n = 1), pruritis ani (n = 1), and rectal prolapse (n = 1). Patient age, weight, and diagnosis were not associated with an increased rate of complication in our institutional experience. All complications were self-limited and did not require intervention. There were no episodes of systemic botulinum toxicity. CONCLUSION: Botox injection into the anal sphincters is accepted practice in children with Hirschsprung disease, severe functional constipation, and internal anal sphincter achalasia and appears to be safe from this review. The precise dosing and age at which complications are more likely to arise could not be ascertained and require further study. LEVEL OF EVIDENCE: IV TYPE OF STUDY: Retrospective cohort study.

ABSTRACT

Designing supportive care for persons with Alzheimer's disease and related dementias in residential care is one of the most challenging issues facing researchers, policymakers, and facility administrators. To gain a better knowledge of the types of special care offered by adult care residences (ACRs) and assisted living facilities, the results of a survey of all licensed ACRs in the state of Virginia are presented. Examined are the facilities with special care units (SCUs) and special programs (SPs), the organizational characteristics of facilities that offer special care, the characteristics of existing SCUs and SPs, and the opinions of owners/operators on the elements needed for establishing these units and programs. The discussion focuses on improvements needed within special care and the implications of the views of owners/operators about special care.
