Improvement of Pretibial Myxedema Following Administration of Teprotumumab.

Pretibial myxedema (PTM) is a rare complication of Graves' disease. It is characterized by non-pitting edema with hyperpigmented hyperkeratotic papules and plaques on bilateral lower legs. Effective treatments for patients with PTM are lacking. The etiology of PTM is unknown; however, it may be similar to the mechanism of thyroid-associated ophthalmopathy (TAO). Activated fibroblasts produce inflammatory cytokines and synthesize excessive glycosaminoglycans (GAG) that accumulate in the dermis and subcutaneous tissue. A recent, novel pathway implicates IGF-1 receptor as a mediator in this process. We present two patients with refractory PTM that improved following treatment with teprotumumab, an IGF-1 receptor inhibitor approved for use in TAO.

Allergic contact dermatitis: Patient diagnosis and evaluation.

Allergic contact dermatitis resulting from exposure to a chemical or chemicals is a common diagnosis in the dermatologist's office. We are exposed to hundreds of potential allergens daily. Patch testing is the criterion standard for diagnosing the causative allergens responsible for allergic contact dermatitis. Patch testing beyond standard trays is often needed to fully diagnose patients, but not all dermatology practices have access to this testing procedure or these allergens. In order to adequately evaluate patients, physicians must understand the pathophysiology of the disease process and be well versed in the proper evaluation of patients, indications for patch testing, proper testing procedure, and other diagnostic tools available and be aware of new and emerging allergens.

Allergic contact dermatitis: Patient management and education.

Allergic contact dermatitis is a common diagnosis resulting from exposure to a chemical or chemicals in a patient's personal care products, home, or work environment. Once patch testing has been performed, the education and management process begins. After the causative allergens have been identified, patient education is critical to the proper treatment and management of the patient. This must occur if the dermatitis is to resolve. Detailed education is imperative, and several resources are highlighted. Photoallergic contact dermatitis and occupational contact dermatitis are other considerations a clinician must keep in mind.

Bed bugs.

The term bed bug is applied to 2 species of genus Cimex: lectularius describes the common or temperate bed bug, and hemipterus its tropical cousin. Cimex lectularius is aptly named; its genus and species derive from the Latin words for bug and bed, respectively. Though the tiny pest is receiving increased public attention and scrutiny, the bed bug is hardly a new problem.

Palliative effect of capecitabine and cetuximab for refractory metastatic squamous cell carcinoma of the perineum in epidermodysplasia verruciformis.

A teenage girl presented with multiple warty skin lesions and had a diagnosis of epidermodysplasia verruciformis made several years later. Later in life she presented with an extensive SCC in situ in her gluteal crease that was surgically resected with wide margins. Despite this treatment, the lesion recurred with extension onto her lower back. Biopsies at the time confirmed SCC in situ of the perianal tissue and invasive SCC above her gluteal cleft.

Recent Global Trends and Hotspots in Occipitocervical Fusion: A Bibliometric Analysis and Visualization Study.

Occipitocervical arthrodesis has a variety of indications to treat craniocervical and atlantoaxial pathologies for which a selective cervical fusion would not provide sufficient stability. Over time, the indications for occipitocervical fusions (OCF) have evolved, as new technologies and surgical techniques were developed. In this bibliometric analysis, we aim to explore the progression of OCF literature over time, analyzing the trends in publications and citations, publishing countries and authors, keywords and topics. The Web of Science database was used for data retrieval on July 3rd, 2024, with the search "occipitocervical fusion" OR "occipito-cervical fusion" OR "occipitocervical arthrodesis" OR "occipital cervical fusion" OR "occipital cervical arthrodesis" OR ("OCF" AND "spine surgery"). Excel was used to create the citation analysis and publication trend figures, along with the publishing countries and author analysis. The bibliometric software VosViewer was used to generate the keyword co-occurrence network visualizations. Overall, 762 articles were extracted. The number of pertinent publications and citations increased until 2020 before beginning to decrease. We found that Ehlers Danlos syndrome (EDS) has become a more prevalent topic, as the association between EDS and craniocervical instability has received further scrutiny. "Dysphagia" continues to be a commonly cited topic, while, conversely, rheumatoid arthritis has decreased in publication frequency, possibly related to advances in medical management and surgical techniques. Overall, the United States of America, China, and Japan are the top publishing countries. This analysis of OCF literature provides a helpful overview of emerging trends and clinician concerns, especially as seen through the perspective of time.

The hidden risk: Intracranial hemorrhage following durotomies in spine surgery.

Objective: Intracranial hemorrhage (ICH) after durotomy in elective spine surgery, though rare, can pose a significant risk to patient outcomes. Spine surgeries bear a risk of dural tears (DT) with potential of postoperative cerebrospinal fluid leakage (PCSFL). Excessive PCSFL can precipitate a decrease in intracranial pressure, potentially leading to ICH. Literature on ICH as a postoperative complication is scarce. The aim was to assess the incidence and risk factors of ICH in patients undergoing elective spine surgery. Methods: Utilizing the 2020 National Impatient Sample (NIS) adults (>18 years) were selected by primary procedure category codes for spine fusion, discectomy, spinal cord decompression and cervicothoracic/lumbosacral nerve decompression. Exclusion criteria were trauma and malignancy. The primary outcome was occurrence of ICH. Comparative analysis and a multivariable logistic regression were used to identify independent risk. Results: In total, 40,990 patients met our criteria with an incidence of ICH at 0.08%. The ICH-group showed an increased length of stay and higher mortality compared to the control group. Spinal cord decompression, DT and PCSFL were significantly more frequent in patients with ICH. Alcohol, drug abuse and hypertension were significantly more prevalent in patients with ICH. DT, alcohol abuse and hypertension were independent risk factors for ICH. Conclusions: This study underscores the rarity and severity of ICHs following elective spine surgery, emphasizing awareness and looking for possible preventive measures. Our finding suggests that DT, as a complication of surgical techniques, as well as alcohol abuse and hypertension are significant predictors of ICH.

A survey of dermatology resident education in cosmetic procedures.

BACKGROUND: The demands for cosmetic procedures are increasing. Dermatologists perform many of these procedures, therefore adequate education and training during residency is important. Surveys demonstrate dermatology residents desire more training even while faculty members believe this has already become a more prominent feature of resident education. OBJECTIVE: We sought to assess the time and methods dedicated to education and training of cosmetic procedures in dermatology residency. METHODS: A 26-question survey was developed and electronically distributed in May 2010 to dermatology program directors via the Association of Professors of Dermatology list-serve with their approval. Program directors were asked to forward the e-mail to their instructors of cosmetic/procedural dermatology, and chief residents. Responses were anonymous. RESULTS: A total of 86 responses were collected. In all, 67% (n = 54) of respondents had formal lectures focusing on cosmetic dermatology. Lecture topics reported by more than 50% of respondents included botulinum toxin injection, lasers, soft tissue augmentation, chemical peels, and sclerotherapy. Topics such as dermabrasion, liposuction, and scar revision were less commonly taught. The most commonly encountered and performed procedures were botulinum toxin injection and lasers (100%, n = 86); 98.8% (n = 85) encounter soft tissue augmentation and 95.4% (n = 82) encounter both chemical peels and sclerotherapy. Resident experience performing procedures as the first assistant or as the first surgeon varied widely. LIMITATIONS: The limitations of this study are that the data were subjectively reported so results may differ from the true amount of time spent in any activity. The data may be biased by the population that responded as they may have strong opinions supporting or opposing training in cosmetic procedures. The data also may have been skewed by the small percentage of participants who were instructors of cosmetic dermatology (21%), chief residents (20%), and others respondents (8% total). CONCLUSION: The results demonstrate the variability of training in cosmetic procedures. The challenge for programs is to find the balance between insufficiency and overemphasis. The results of this study will hopefully assist programs in determining the quantity and methods of resident training in cosmetic procedures.

Current leadership training in dermatology residency programs: a survey.

BACKGROUND: Residents and physicians frequently find themselves in leadership roles. Current residency curricula focus on the development of clinical knowledge and technical skills. A previous survey of Penn State Dermatology graduates demonstrated the perceived need and benefit of a formalized leadership curriculum in this selected group. OBJECTIVES: We sought to identify and measure the perceived need and benefit of formalized leadership training and investigate opinions regarding leadership theory from the perspective of dermatology residency program directors and chief residents nationally. METHODS: A survey containing 26 questions related to leadership theory and training were mailed to all US dermatology residency programs. RESULTS: In all, 91% of program directors and chief residents agreed that leadership skills could be taught through observation and training. A total of 78% of respondents agreed that leadership training is important during dermatology residency training. In all, 66% agreed that a formalized leadership curriculum would help residents become better resident supervisors and physicians. Only 13% reported having a formalized leadership curriculum. Participants most frequently reported learning leadership through observation and modeled behavior. A total of 15% of chief residents believed their faculty did not effectively model leadership, whereas only 2% of the program directors believed the same (P = .01). LIMITATIONS: In all, 62% (68/109) of programs surveyed returned at least one response from the program director or chief resident. A total of 39% (42/109) had responses from both the program director and the chief resident. Because of the voluntary nature of the survey, response bias could not be excluded. CONCLUSION: Most program directors and chief residents believe leadership skills can be cultivated through observation and training. Leadership curriculum is not part of most residency programs.

Umbilical endometriosis in a woman with bicornuate uterus.

A 39-year-old woman presented for evaluation of a tender nodule on the umbilicus that had been present for 6 months. She stated that it had slowly been increasing in size and would occasionally open up and crust over with dried blood. Physical examination revealed a 4-mm firm, tender, brown papule in the umbilicus (Figure 1). She had a history of chronic pelvic pain and exploratory laparoscopy for endometriosis 10 years prior, at which time the diagnosis ofa bicornuate uterus was made. Subsequently, hysterectomy was performed (Figure 2) at which time the entire umbilical lesion was excised. Histopathology revealed branching tubular glands in the dermis lined by stratified columnar epithelium, surrounded by small cells with scant cytoplasm, characteristic of proliferative-phase endometrial stroma (Figure 3 and Figure 4). These findings were consistent with a diagnosis of umbilical endometriosis (Villar's nodule). Subsequent examination revealed no evidence of recurrence.

A Cautionary Tale of a Complex Peri-Trochanteric Fracture in a Very Important Person (VIP) Patient at a Community-Based Hospital: A Case Report.

Peri-trochanteric fractures with an extension into the femoral neck are relatively rare. Due to the lack of a defined treatment in the literature, these fractures pose a challenge to orthopedic surgeons. This case report highlights the value of timing to surgical intervention, choosing the appropriate operative course, not treating very important person (VIP) patients differently than standard patients, and decreasing unnecessary costs for the patient and the US healthcare system. An 85-year-old male VIP patient presented to the emergency department (ED) with a left peri-trochanteric fracture with an extension into the ipsilateral femoral neck. The initial plan was to perform arthroplasty with diaphyseal fixation. However, the community-based hospital would have to wait two to three days for the proper implants, and the patient insisted on being treated at this hospital. Due to concerns about increased mortality with delayed treatment, the patient underwent short cephalomedullary nail (CMN) fixation the next day. On postoperative day (POD) 49, a pop was heard and felt while ambulating, and radiographs revealed substantial lateral cutout of the CMN and subsidence of the femoral head. On POD 54, the patient underwent a successful left total hip arthroplasty using a modular diaphyseal press-fit femoral component, which resulted in an uneventful recovery. This case illustrates a cautionary tale in choosing the appropriate operative course for a VIP patient with a peri-trochanteric fracture extending into the femoral neck (a relatively rare fracture type that has no clearly defined treatment option). This is imperative to reduce pain and length of stay for the patient, postoperative complications, and cost. Based on the results from the second procedure and weighing the risk of prolonged treatment, the authors believe that this patient would likely have benefited from a primary arthroplasty procedure given his body habitus and complex fracture pattern.

Impact of medical scribes on physician and patient satisfaction in dermatology.

Physician burnout and its association with the use of electronic health records (EHRs) is well known. The impact of scribes for academic dermatologists and their patients needs to be explored. As physician burnout increases, system-based solutions are needed. To assess the impact of a scribe on physician and patient satisfaction at an academic dermatology clinic. Prospective, pre-post-pilot intervention study. During the pilot intervention, clinicians had clinic sessions with and without a scribe. We assessed changes in (1) clinician satisfaction and burnout, (2) time spent on EHR, and (3) patient satisfaction. An electronic 7-item baseline survey, 23-item mid-study survey, and a 22-item end-of-study survey to assess clinician burnout and feedback on satisfaction with medical scribes. A 19-item post visit satisfaction survey was given to patients. EHR was queried to compare amount of time spent on EHR, closure of charts, and number of patients seen during scribe coverage and at baseline. Of the six clinicians, 100% felt that there was value to scribe support. Physician burnout was low at baseline and did not change post-pilot. Active documentation time, on average, decreased by 67% per patient with a 28% increase in patients seen per clinic. Over 88% of patients disagreed with the statement, "I was uncomfortable disclosing personal information when a scribe was present" (p < 0.001). In an academic dermatology and Mohs surgery setting, medical scribes increased clinician satisfaction without compromising patient satisfaction.

Effects of Cervical Spine Exercise Protocol on Neck Pain, Pericervical Muscle Endurance, and Range of Motion in Medical Students: A Prospective Study.

Introduction Neck pain is a common and debilitating ailment that places a significant burden on the healthcare system. No practical protocols have been published utilizing a portable, commercially available, and affordable device that significantly reduces acute and chronic neck pain. Methods Forty-six young adults with or without mild-to-moderate neck pain completed a six-week neck stretching and strengthening protocol with a portable cervical stretching and strengthening device. The primary outcome was changes to pericervical muscle endurance. Secondary outcomes were changes to cervical range of motion (ROM), neck length, circumference, and subjective pain, flexibility, and strength. Measurements were obtained on study days 0, 21, and 42. Results A significant increase in pericervical muscle endurance was demonstrated across all planes of cervical motion, ranging from 84% to 105%. Cervical ROM improved across all planes of motion but was only significant in right-side bending (5.3°), left rotation (6.2°), and right rotation (7.8°). Subjective pain evaluated via the Numeric Rating Scale (NRS) saw statistically significant improvement as well (1.33 to 0.51). Subjective assessment of participant cervical pain, strength, and flexibility improved 61.3%, 95.7%, and 97.8%, respectively. Conclusions A six-week pericervical muscle stretching and strengthening program increased pericervical endurance and ROM in young adults. Decreased cervical pain was seen using the NRS and modified pain scale across most participants.

Predominant risk factors for tick-borne co-infections in hunting dogs from the USA.

BACKGROUND: Both incidence and geographical range of tick-borne disease has increased across the USA. Similar to people, dogs are hosts for Anaplasma spp., Babesia spp., Ehrlichia spp. and Borrelia burgdorferi. Dogs also share our homes and beds, making them both a sentinel for the ticks in our backyards but also increasing our exposure to ticks. Measures to better track, prevent, and/or treat tick-borne diseases in companion animals can lead to better control and prevention of human tick-borne disease. This study identifies demographic and co-infection risk factors for canine seropositivity to tick-borne infections in a cohort of hunting dogs across the USA. RESULTS: Human patterns of tick-borne disease co-infection in the USA have been predominantly driven by the geographical distribution of the tick vector. Dogs who tested seropositive for Anaplasma spp. were 1.40 times more likely (P = 0.0242) to also test seropositive for Babesia spp. and vice versa (1.60 times more likely, P = 0.0014). Dogs living in the West had 5% lower risk (P = 0.0001) for Ehrlichia spp. seropositivity compared to other regions. Controlling for age and Anaplasma spp. seroprevalence, dogs in all three other regions were 2.30 times more likely (P = 0.0216) to test seropositive for B. burgdorferi than dogs in the West. Dogs seropositive for B. burgdorferi were 1.60 times more likely (P = 0.0473) to be seropositive for Anaplasma spp. CONCLUSIONS: Tick geographical distributions have a prominent impact on the regional distribution of hunting dog exposure to tick-borne diseases. Education concerning regional tick prevalence and disease risk is important for everyone, but particularly dog owners, regarding ticks in their region and protection from infection and co-infection of tick-borne pathogens as they travel or move with their dogs. Dogs are sentinel species for human exposure to ticks, and as such surveillance of canine tick-borne infections and understanding the probability that these infections might be seen together as co-infections helps predict emerging areas where people are more likely to be exposed as well.

ERK Inhibitor LY3214996 Targets ERK Pathway-Driven Cancers: A Therapeutic Approach Toward Precision Medicine.

The ERK pathway is critical in oncogenesis; aberrations in components of this pathway are common in approximately 30% of human cancers. ERK1/2 (ERK) regulates cell proliferation, differentiation, and survival and is the terminal node of the pathway. BRAF- and MEK-targeted therapies are effective in BRAF V600E/K metastatic melanoma and lung cancers; however, responses are short-lived due to emergence of resistance. Reactivation of ERK signaling is central to the mechanisms of acquired resistance. Therefore, ERK inhibition provides an opportunity to overcome resistance and leads to improved efficacy. In addition, KRAS-mutant cancers remain an unmet medical need in which ERK inhibitors may provide treatment options alone or in combination with other agents. Here, we report identification and activity of LY3214996, a potent, selective, ATP-competitive ERK inhibitor. LY3214996 treatment inhibited the pharmacodynamic biomarker, phospho-p90RSK1, in cells and tumors, and correlated with LY3214996 exposures and antitumor activities. In in vitro cell proliferation assays, sensitivity to LY3214996 correlated with ERK pathway aberrations. LY3214996 showed dose-dependent tumor growth inhibition and regression in xenograft models harboring ERK pathway alterations. Importantly, more than 50% target inhibition for up to 8 to 16 hours was sufficient for significant tumor growth inhibition as single agent in BRAF- and KRAS-mutant models. LY3214996 also exhibited synergistic combination benefit with a pan-RAF inhibitor in a KRAS-mutant colorectal cancer xenograft model. Furthermore, LY3214996 demonstrated antitumor activity in BRAF-mutant models with acquired resistance in vitro and in vivo. Based on these preclinical data, LY3214996 has advanced to an ongoing phase I clinical trial (NCT02857270).

Improvised Inguinal Junctional Tourniquets: Recommendations From the Special Operations Combat Medical Skills Sustainment Course.

Effectively and rapidly controlling significant junctional hemorrhage is an important effort of Tactical Combat Casualty Care (TCCC) and can potentially contribute to greater survival on the battlefield. Although the US Food and Drug Administration (FDA) has approved labeling of four devices for use as junctional tourniquets, many Special Operations Forces (SOF) medics do not carry commercially marketed junctional tourniquets. As part of ongoing educational improvement during Special Operations Combat Medical Skills Sustainment Courses (SOCMSSC), the authors surveyed medics to determine why they do not carry commercial tourniquets and present principles and methods of improvised junctional tourniquet (IJT) application. The authors describe the construction and application of IJTs, including the use of available pressure delivery devices and emphasizing that successful application requires sufficient and repetitive training.

Comorbid infections induce progression of visceral leishmaniasis.

BACKGROUND: Visceral leishmaniasis (VL) is a vector borne zoonotic disease endemic in humans and dogs in Brazil. Due to the increased risk of human infection secondary to the presence of infected dogs, public health measures in Brazil mandate testing and culling of infected dogs. Despite this important relationship between human and canine infection, little is known about what makes the dog reservoir progress to clinical illness, significantly tied to infectiousness to sand flies. Dogs in endemic areas of Brazil are exposed to many tick-borne pathogens, which are likely to alter the immune environment and thus control of L. infantum. RESULTS: A cross-sectional study of 223 dogs from an area of Natal, in the Rio Grande do Norte, Brazil, were studied to determine the association between comorbid tick-borne disease and Leishmania infection in this endemic area. The risk of Leishmania seropositivity was 1.68× greater in dogs with tick-borne disease seropositivity compared to those without (Adjusted RR: 1.68, 95% CI: 1.09-2.61, P = 0.019). A longitudinal study of 214 hunting dogs in the USA was conducted to determine the causal relationship between infection with tick-borne diseases and progression of VL. Hunting dogs were evaluated three times across a full tick season to detect incident infection with tick-borne diseases. A logistic regression model with generalized estimating equations to estimate the parameters was used to determine how exposure to tick-borne disease altered VL progression over these three time points when controlling for other variables. Dogs infected with three or more tick-borne diseases were 11× more likely to be associated with progression to clinical VL than dogs with no tick-borne disease (Adjusted RR: 11.64, 95% CI: 1.22-110.99, P = 0.03). Dogs with exposure to both Leishmania spp. and tick-borne diseases were five times more likely to die during the study period (RR: 4.85, 95% CI: 1.65-14.24, P = 0.0051). CONCLUSIONS: Comorbid tick-borne diseases dramatically increased the likelihood that a dog had clinical L. infantum infection, making them more likely to transmit infection to sand flies and people. As an important consequence, reduction of tick-borne disease exposure through topical or oral insecticides may be an important way to reduce progression and transmissibility of Leishmania infection from the canine reservoir to people.

Optimization of a dihydropyrrolopyrazole series of transforming growth factor-beta type I receptor kinase domain inhibitors: discovery of an orally bioavailable transforming growth factor-beta receptor type I inhibitor as antitumor agent.

In our continuing effort to expand the SAR of the quinoline domain of dihydropyrrolopyrazole series, we have discovered compound 15d, which demonstrated the antitumor efficacy with oral bioavailability. This effort also demonstrated that the PK/PD in vivo target inhibition paradigm is an effective approach to assess potential for antitumor efficacy. The dihydropyrrolopyrazole inhibitor 15d (LY2109761) is representative of a novel series of antitumor agents.
