Long-term outcomes of glued (sutureless) amniotic membrane transplantation in acute Stevens-Johnson syndrome/toxic epidermal necrolysis: a comparative study.

PURPOSE: To compare the effectiveness and efficiency of a glued (sutureless) technique for amniotic membrane transplantation (AMT) with a traditional sutured one in the setting of acute Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). METHODS: This retrospective cohort study evaluated all patients diagnosed with SJS/TEN between 2008 and 2020 within our hospital network who received AMT in the acute phase according to our protocol and had at least one ophthalmic follow-up in the chronic phase. Primary outcomes included best-corrected visual acuity (BCVA) at the most recent visit, presence of a severe ocular complication (SOC) via predefined criteria, time to procedure and duration of procedure. Random effects model analysis was used to evaluate the impact of potential covariates on outcome measures. RESULTS: A total of 23 patients (45 eyes) were included: 14 patients (27 eyes) in the AMT suture group and 9 patients (18 eyes) in the AMT glue group. There was no difference between the two groups in BCVA at the most recent visit (p=0.5112) or development of a SOC (p=1.000). The glue method was shorter in duration than the suture method (p<0.001). Random effects model additionally indicated that there was no difference in BCVA at most recent follow-up between patients who had received glued versus sutured AMT (p=0.1460). CONCLUSIONS: Our glued technique for AMT is as effective as our sutured technique in stabilising the ocular surface and mitigating chronic ocular complications in SJS/TEN. The glued technique is also shorter in duration and performed more expediently than the sutured technique.

Community-Acquired Pneumonia in the Immunocompromised Host: Epidemiology and Outcomes.

Background: The epidemiology and outcomes of community-acquired pneumonia (CAP) in immunocompromised hosts (ICHs) are not well defined. The objective of this study was to define the epidemiology and outcomes of CAP in ICHs as compared with non-ICHs. Methods: This ancillary study included a prospective cohort of hospitalized adult Louisville residents with CAP from 1 June 2014 to 31 May 2016. An ICH was defined per the criteria of the Centers for Disease Control and Prevention. Geospatial epidemiology explored associations between ICHs hospitalized with CAP and income level, race, and age. Mortality for ICHs and non-ICHs was evaluated during hospitalization and 30 days, 6 months, and 1 year after hospitalization. Results: A total of 761 (10%) ICHs were identified among 7449 patients hospitalized with CAP. The most common immunocompromising medical conditions or treatments were advanced-stage cancer (53%), cancer chemotherapy (23%), and corticosteroid use (20%). Clusters of ICHs hospitalized with CAP were found in areas associated with low-income and Black or African American populations. Mortality by time point for ICHs vs non-ICHs was as follows: hospitalization, 9% vs 5%; 30 days, 24% vs 11%; 6 months, 44% vs 21%; and 1 year, 53% vs 27%, respectively. Conclusions: Approximately 1 in 10 hospitalized patients with CAP is immunocompromised, with advanced-stage cancer being the most frequent immunocompromising condition, as seen in half of all patients who are immunocompromised. Risk for hospitalization may be influenced by socioeconomic disparities and/or race. ICHs have a 2-fold increase in mortality as compared with non-ICHs.

Supernumerary lacrimal puncta: case series and review of the literature.

We report a case series of supernumerary puncta-canaliculi, a very rare congenital anomaly, and describe different clinical presentations and new treatment options. This is a retrospective chart review of patients diagnosed with supernumerary lacrimal puncta during the time between June 2015 and December 2021 at the Research Institute of Ophthalmology, Giza, Egypt. Four patients (two females and two males) with a mean presenting age of 54 ± 14 years had unilateral double puncta. Of those four patients, three had double puncta on the right lower eyelid whereas one had double puncta on the left upper and lower eyelid. In one of the three patients, the double puncta anomaly was an incidental finding, and the patient was asymptomatic. The other three patients had associated epiphora. All four patients were found to have patent double puncta with no mechanical obstruction. No surgical interventions were necessary for all four patients as one resolved after discontinuing the topical eye drops. Another patient resolved after the diagnostic probing of the puncta, and the third asymptomatic patient required no interventions. Epiphora in the fourth patient resolved with botulinum toxin injection in the lacrimal gland. Accessory lacrimal puncta can present in patients as an incidental asymptomatic finding or patients may present with epiphora. Patients who present with unilateral epiphora, dry eye, or canaliculitis should be carefully evaluated with a detailed slit-lamp examination using lid eversion to appreciate potentially easily missed supernumerary lacrimal puncta.

Ocular involvement in Mycoplasma induced rash and mucositis: A systematic review of the literature.

Mycoplasma pneumoniae induced rash and mucositis (MIRM) is a relatively newly identified clinical entity which is characterized by mucocutaneous manifestations in the setting of Mycoplasma infection. Though a clinically distinct disease, MIRM exists on a diagnostic continuum with entities including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and the recently described reactive infectious mucocutaneous eruption (RIME). In this systematic review, we discuss published findings on the epidemiology, clinical manifestations, diagnosis, and management of MIRM, with an emphasis on ocular disease. Lastly, we discuss some of the most recent developments and challenges in characterizing MIRM with respect to the related diagnosis of RIME.

An alternative model for assessing mortality risk in Stevens Johnson syndrome/toxic epidermal necrolysis using a random forests classifier: A pilot study.

Introduction: Mortality risk prediction is an important part of the clinical assessment in the Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) patient. The SCORTEN and ABCD-10 scoring systems have been used as predictive clinical tools for assessing this risk. However, some of the metrics required in calculating these scores, such as the total body surface area (TBSA) involvement, are difficult to calculate. In addition, TBSA involvement is calculated in a variety of ways and is observer dependent and subjective. The goal of this study was to develop an alternative method to predict mortality in patients with SJS/TEN. Methods: Data was split into training and test datasets and preprocessed. Models were trained using five-fold cross validation. Out of several possible candidates, a random forests model was evaluated as being the most robust in predictive power for this dataset. Upon feature selection, a final random forests model was developed which was used for comparison against SCORTEN. Results: The differences in both accuracy (p = 0.324) and area under the receiver operating characteristic curve (AUROC) (p = 0.318) between the final random forests model and the SCORTEN and ABCD-10 models were not statistically significant. As such, this alternative method performs similarly to SCORTEN while only requiring simple laboratory tests from the day of admission. Discussion: This new alternative can make the mortality prediction process more efficient, along with providing a seamless implementation of the patient laboratory tests directly into the model from existing electronic health record (EHR) systems. Once the model was developed, a web application was built to deploy the model which integrates with the Epic EHR system on the Fast Healthcare Interoperability Resources (FHIR) Application Programming Interface (API); this only requires the patient medical record number and a date of the lab tests as parameters. This model ultimately allows clinicians to calculate patient mortality risk with only a few clicks. Further studies are needed for validation of this tool.

Visual function and quality of life in patients with Stevens-Johnson syndrome who received acute protocol-based ocular care.

Purpose: To report visual function and quality of life (VF/QOL) using the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) and the ocular surface disease index (OSDI) in patients in the chronic phase of Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). Methods: The NEI-VFQ-25 questionnaire was administered to 15 patients who received protocol-based care in the form of topical medications with or without amniotic membrane transplantation (AMT) for acute SJS/TEN. The scores obtained were compared with scores from a healthy population. The associations between the NEI-VFQ-25 and dry eye symptoms as measured by OSDI questionnaire were also studied. Results: Patients were surveyed at a mean of 4.47 ± 2.22 years after acute SJS/TEN. Eleven patients received AMT in the acute phase. The median best corrected visual acuity at the time of administration of the questionnaire was 20/20. The mean composite NEI-VFQ-25 score was 86.48 ± 12. Patients who received protocol-based treatment in the acute phase of SJS/TEN had comparable NEI-VFQ-25 scores with healthy subjects on all subscales except ocular pain (p = 0.027) and mental health (p = 0.014), which were significantly reduced. The NEI-VFQ-25 composite scores significantly correlated with OSDI (R = -0.75, p = 0.001). Conclusion: A protocol-based management strategy composed of early ophthalmic evaluation, grading based on severity, the use of topical corticosteroids and AMT in the acute phase of SJS/TEN in patients with ocular complications helped preserve the VF/QOL. This study highlights the impact of appropriate management of the ocular complications in the acute phase of SJS/TEN.

Hereditary Thrombophilia Testing Among Hospitalized Patients: Is It Warranted?

Background Hereditary thrombophilias (HTs) are a group of inherited disorders that predispose the carrier to venous thromboembolism (VTE). It is estimated that 7% of the population has some form of HT. Although testing for HT has become routine for many hospitalized patients, knowing when to order the tests and how to interpret the results remains challenging. In the United States, there are no clear guidelines regarding testing for HT. We conducted a study to evaluate the utilization of HT testing among hospitalized patients to examine its impact on immediate management decisions and overall cost burden. In addition, we discuss the common reasons for healthcare providers to order these tests and review the data behind these reasons in the literature. Methodology A retrospective analysis of 2,402 patients who underwent HT testing between February 1, 2016, and January 31, 2018, was conducted. Eligible patients had at least one HT test ordered during hospitalization. The primary outcome was to determine the incidence of positive actionable tests. A positive actionable test was defined as a positive result that changed the anticoagulation intensity, type, or duration. Patients with a history of previous VTE, ongoing medical conditions requiring life-long anticoagulation, or unprovoked VTE were considered non-actionable. Results Among the 2,402 patients, 954 patients met the inclusion criteria with a mean age of 54 years. A total of 397 (41.6%) tests were ordered for acute VTE, while the rest were for non-VTE conditions, such as stroke, pregnancy complications, peripheral artery diseases, and others. Only 89 positive tests were actionable (14% of the positive tests, and 9.3% of the total ordered tests). There was a statistically significant association between increasing age and having both a positive test result (p = 0.006) and an actionable test (p = 0.046). The total cost of ordering these tests was estimated to be $566,585. Conclusions HT testing in the inpatient setting did not alter management in many cases and was associated with increased healthcare costs. The decision to order these tests should be individualized based on the clinical scenario.

Patients' Preference Regarding Laser Photocoagulation or Cryoretinopexy for the Treatment of Retinal Pathology.

Purpose: High-risk peripheral retinal pathology can be prophylactically treated with both laser photocoagulation (laser) and cryoretinopexy (cryopexy). We sought to identify a possible preference by patients toward one modality and any underlying association. Methods: A single-center survey was conducted of patients with peripheral retinal pathology who received both laser and cryopexy at Associated Retinal Consultants (Royal Oak, Michigan). The main outcome measure was the preferred treatment modality. Results: Patients reported more pain after cryopexy (46%) than laser (11%). Most patients felt it was easier to recover from laser (52%) than cryopexy (13%). Overall, patients preferred laser (60%) to cryopexy (25%), with a minority (15%) having no preference. There was a negative relationship between a patient's likelihood of preferring cryopexy and the number of applications (P = .009). Conclusions: Most patients preferred laser (60%) to cryopexy. If cryopexy is performed, minimizing the number of freezes may improve the patient's experience and recovery.

Cone-Beam Computed Tomography-Guided Electromagnetic Navigation for Peripheral Lung Nodules.

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) is a minimally invasive technology for the diagnosis of peripheral pulmonary nodules. However, ENB is limited by the lack of real-time confirmation of various biopsy devices. Cone-beam computed tomography (CBCT) could increase diagnostic yield by allowing real-time confirmation to overcome the inherent divergence of nodule location. OBJECTIVES: The aim of this study was to assess the diagnostic yield of ENB plus CBCT as compared with ENB alone for biopsy of peripheral lung nodules. METHOD: We conducted a retrospective study of patients undergoing ENB before and after the implementation of CBCT. Data from 62 consecutive patients with lung nodules located in the outer two-thirds of the lung who underwent ENB and combined ENB-CBCT were collected. Radial endobronchial ultrasound was used during all procedures as well. Diagnostic yield was defined as the presence of malignancy or benign histological findings that lead to a specific diagnosis. RESULTS: Thirty-one patients had ENB-CBCT, and 31 patients had only ENB for peripheral lung lesions. The median size of the lesion for the ENB-CBCT group was 16 (interquartile range (IQR) 12.6-25.5) mm as compared to 21.5 (IQR 16-27) mm in the ENB group (p = 0.2). In the univariate analysis, the diagnostic yield of ENB-CBCT was 74.2% and ENB 51.6% (p = 0.05). Following multivariate regression analysis adjusting for the size of the lesion, distance from the pleura, and presence of bronchus sign, the odds ratio for the diagnostic yield was 3.4 (95% CI 1.03-11.26, p = 0.04) in the ENB-CBCT group as compared with ENB alone. The median time for the procedure was shorter in patients in the ENB-CBCT group (74 min) than in those in the ENB group (90 min) (p = 0.02). The rate of adverse events was similar in both groups (6.5%, p = 0.7). CONCLUSIONS: The use of CBCT might increase the diagnostic yield in ENB-guided peripheral lung nodule biopsies. Future randomized clinical trials are needed to confirm such findings.

BMI is Associated with Coronavirus Disease 2019 Intensive Care Unit Admission in African Americans.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has disproportionately impacted the African American community. This study aims to identify the risk factors for severe COVID-19 disease in African American patients. METHODS: This was a retrospective cross-sectional analysis of African American patients with COVID-19 treated between March 12 and April 9, 2020, at a single tertiary center. The primary outcome of interest was severe disease defined as those requiring intensive care unit (ICU) admission. RESULTS: The study included 158 consecutive patients. The mean age was 57 years, and 61% were women. The mean (SD) of BMI was 33.2 (8.6) kg/m2 . Overall, patients admitted to the ICU were older (62 vs. 55 years, P = 0.003) and had higher BMI (36.5 kg/m2 vs. 31.9 kg/m2 , P = 0.002). In unadjusted and adjusted analysis, the factors most associated with ICU admission in this sample were age (adjusted odds ratio [aOR]: 1.073; 95% CI: 1.033-1.114), BMI (aOR: 1.115; 95% CI: 1.052-1.182), and lung disease (aOR: 3.097; 95% CI: 1.137-8.437). CONCLUSIONS: This study identified risk factors for severe disease in COVID-19, specifically in an African American population. Further inclusive research aimed at optimizing clinical care relevant to the African American population is critical to ensure an equitable response to COVID-19.

Disparities in diabetes-related multiple chronic conditions and mortality: The influence of race.

AIMS: The aims of this study are to confirm disparities in diabetes mortality rates based on race, determine if race predicts combinations of diabetes and multiple chronic conditions (MCC) that are leading causes of death (LCD), and determine if combinations of diabetes plus MCC mediate the relationship between race and mortality. METHODS: We performed a retrospective cohort study of 443,932 Medicare beneficiaries in the State of Michigan with type 2 diabetes mellitus and MCC. We applied Cox proportional hazards regression to determine predictors of mortality. We applied multinomial logistic regression to determine predictors of MCC combinations. RESULTS: We found that race influences mortality in Medicare beneficiaries with Type 2 diabetes mellitus and MCC. Prior to adjusting for MCC combinations, we observed that Blacks and American Indian/Alaska Natives have increased risk of mortality compared to Whites, while there is no difference in mortality between Hispanics and Whites. Regarding MCC combinations, Black/African American beneficiaries experience increased odds for most MCC combinations while Asian/Pacific Islanders and Hispanics experience lower odds for MCC combinations, compared to Whites. When adjusting for MCC, mortality disparities observed between Whites, Black/African Americans, and American Indians/Alaska Natives persist. CONCLUSIONS: Compared to Whites, Black/African Americans in our cohort had increased odds of most MCC combinations, and an increased risk of mortality that persisted even after adjusting for MCC combinations.

An Unusual Case of Diffuse Alveolar Hemorrhage as a Clinical Manifestation of Atypical Hemolytic Uremic Syndrome: A Case Report.

Hemolytic uremic syndrome (HUS) is a constellation of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal injury. HUS is subcategorized into primary or secondary HUS. Primary HUS is synonymous with atypical HUS (aHUS) and is attributed to genetic complement deficiency. Diffuse alveolar hemorrhage (DAH) is a serious condition complicating multiple systemic conditions. aHUS presenting as DAH is exceedingly rare. In this case, we present a 75-year-old male patient who presented with generalized weakness, malaise, and hemoptysis. He was found to have hemolytic anemia and thrombocytopenia, with elevated creatinine. Bronchoscopy confirmed DAH. He was started on plasmapheresis with a suboptimal response. aHUS was suspected and the patient was started on eculizumab with subsequent laboratory and clinical improvement. HUS and aHUS can present as DAH. It is very important to recognize both conditions as both are life threatening with high morbidity and mortality.

Xanthogranulomatous Pyelonephritis Causing Renocolic Fistula Presenting as Symptomatic Anemia.

Renocolic fistula is a rare clinical finding that is most commonly iatrogenic after surgical intervention. Herein, we present a case of renocolic fistula secondary to xanthogranulomatous pyelonephritis (XGP) with a subtle presentation as anemia. A 40-year-old female was found to have a hemoglobin of 6.5 g/dL after presenting for worsening fatigue. A urinalysis was remarkable for numerous white blood cell (WBC), positive bacteria, and nitrite. As part of her anemia workup, an esophagogastroduodenoscopy (EGD) was done which was normal while a colonoscopy showed a fistula opening with surrounding nodularity close to the splenic flexure of the colon. A computed tomography (CT) scan of the abdomen and pelvis with contrast showed chronic left kidney pyelonephritis with multiple contiguous abscesses in the inferior left kidney in addition to a staghorn calculus concerning for XGP. The patient was started on antibiotics and underwent laparotomy with repair of the renocolic fistula, partial omentectomy, and left nephrectomy. She tolerated the surgery well and was discharged with a stable hemoglobin. XGP is a rare type of chronic pyelonephritis that is usually a result of chronic obstruction by an infected stone. Spontaneous renocolic fistulas are rare nowadays with the advancement in antibiotics and renal stones treatment.

Posterior reversible encephalopathy syndrome while receiving irinotecan with fluorouracil and folinic acid for metastatic gastric cancer.

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiographic syndrome with seizures, headache, altered mental status and visual disturbances. It is typically associated with posterior cerebral white matter oedema on neuroimaging. There is an increasing number of cases of PRES reported with different chemotherapeutic protocols. However, PRES is rarely reported in association with irinotecan, fluorouracil and folinic acid (FOLFIRI). We report a 28-year-old female patient with a history of Stage IV gastric cancer who presented with abdominal pain and recurrent vomiting that was thought to be related to a partial intestinal obstruction secondary to peritoneal metastasis. Eventually, she was treated with FOLFIRI. A few hours after initiation of the fluorouracil infusion in the second cycle, she developed a tonic-clonic seizure. MRI of the brain showed multiple bilateral T 2 and flair hyperintense cortical and subcortical lesions suggestive of PRES. Other causes of PRES were excluded, as well as brain metastasis. Unfortunately, the patient developed septic shock and died a few days after her presentation.

Metastatic Lung Adenocarcinoma Presenting with Hypereosinophilia.

Lung cancer is one of the most common malignancies in both male and female patients. It is classified into small cell lung cancers and non-small cell lung cancers. Lung adenocarcinoma is a subtype of non-small cell lung cancer and accounts for the highest prevalence of lung cancer. Eosinophils are white blood cells (WBCs) that originate from the granulocytic lineage. Hypereosinophilia is a rare condition characterized by an absolute eosinophil count (AEC) of more than 1500 cells/µL. This is different from eosinophilia, which is defined as an absolute eosinophil count of more than 500 cells/µL. Hypereosinophilia is associated with several conditions, including allergic disorders, helminth infections, rheumatologic disorders, and hematologic malignancies. Paraneoplastic eosinophilia is a rare finding in solid malignancies. Herein, we report the case of a 55-year-old male who presented with shortness of breath and chest pain and whose workup showed metastatic lung adenocarcinoma associated with hypereosinophilia in the absence of a primary bone marrow disorder.

Pylephlebitis Caused by Actinomyces Bacteremia.

Pylephlebitis is a thrombophlebitis of the portal vein or its branches, which usually occurs as a complication of intra-abdominal infections that are drained by the portal vein, most commonly as a result of diverticulitis or appendicitis. Diagnosis of pylephlebitis is achieved by visualizing a portal vein thrombosis in a patient with bacteremia or a recent intra-abdominal infection. Many microorganisms have been reported to cause this infection. However, Actinomyces has never been reported before as a cause of pylephlebitis. Here, we describe a case of a 56-year-old female who had pylephlebitis that was caused by Actinomyces bacteremia and was treated with intravenous antibiotics.

Academic Productivity of US Cardiothoracic Surgical Centers.

BACKGROUND AND AIM: We investigated which metrics represent valid correlates of the academic productivity of cardiothoracic (CT) surgical centers. METHODS: We collected data from 57 US academic CT surgical groups (663 surgeons), including H index and institutional role of each surgeon, ranking by US News & World Report (USNWR) and NIH funding, and designation as department versus division. RESULTS: Academic productivity (median H-index of each group) was significantly different across institutions (p < 0.001). Several USNWR hospital categories ("Honor Roll", "Adult Cardiology and Heart Surgery", "Adult Pulmonology", "Adult Cancer") and medical school ranking for research were associated with differences in academic productivity, while ranking by NIH funding or designation as department versus division was not. Groups with chairperson's individual H-index ≥50 were overall more productive than those with chairperson's H-index <50 (median H-index: 18 vs. 14; p = 0.005). CONCLUSIONS: USNWR rankings provide a good representation of academic productivity, while NIH funding ranking or designation as department versus division does not. The individual productivity of the chairperson is correlated with that of the whole group. doi: 10.1111/jocs.12773 (J Card Surg 2016;31:423-428).

Characteristics of cardiothoracic surgeons practicing at the top-ranked US institutions.

BACKGROUND: We aimed to determine which factors distinguish cardiothoracic (CT) surgeons practicing at the top-ranked US institutions from their peers. METHODS: Using online resources, we collected demographics, training information and academic metrics of 694 cardiac (n=489; 70%) and thoracic (n=205; 30%) surgeons practicing at 57 preeminent US institutions, including those with the highest US News & World Report ranking ("top CT centers"). RESULTS: Two hundred and ninety-nine (43.1%) CT surgeons were practicing at the 18 "top CT centers" and had higher academic productivity (publications, citations) than their peers. While there was no difference in the proportion of international medical graduates (IMGs) (21.4% overall) or of surgeons with a PhD degree (9.4% overall) across institutions, the "top CT centers" had a higher proportion of faculty who received their entire CT training abroad (10.4% vs. 5.8%; P=0.038) or at highly-ranked US institutions. Those who published more during their early career years (residency, fellowship and first 5 years as faculty) were more likely to attain academic (professorship) and institutional leadership (division/department chair) positions and to practice at the "top CT centers". Women represented a minority (7.3% overall; 5.1% of cardiac vs. 12.7% of thoracic surgeons, P<0.001), but with growing prevalence among younger faculty and without differences across institutions. CONCLUSIONS: CT surgeons of the best US centers have a more international background and received their training at highly-ranked institutions. Early academic productivity is associated with life-long career achievements, with special importance of the first 5 years as faculty. Women represent a growing proportion of the CT surgical workforce.
