Posttraumatic Compressive Neuropathy of the Deep Motor Branch of the Ulnar Nerve Caused by Heterotopic Ossification.

We report a case of posttraumatic compressive neuropathy of the deep motor branch of the ulnar nerve occurring in the setting of heterotopic ossification following a direct blow to the hypothenar eminence. Over several weeks, the patient developed ring and little finger claw deformities and atrophy of his first dorsal interosseous and adductor pollicis muscles with sparing of sensation. Electromyography and nerve conduction study localized the area of injury, and computed tomography confirmed the presence of heterotopic bone near the deep motor branch of the ulnar nerve. Intraoperatively, the deep motor branch of the ulnar nerve was under tension as it traversed volarly over the hook of hamate and heterotopic bone. Decompression of the deep motor branch of the ulnar nerve with resection of heterotopic bone and the hook of hamate was performed. Six months postoperatively, the patient demonstrated resolution of clawing and improving strength of his ulnar nerve innervated intrinsic muscles.

Associations between humiliation, shame, self-harm and suicidality among adolescents and young adults: A systematic review.

BACKGROUND: Suicide is the second leading cause of death among young people worldwide. Research indicates that negative social contexts involving familial and peer relationships have far-reaching influences on levels of suicidality in later life. While previous systematic reviews have focused on evaluating associations between negative life events such as abuse and bullying in childhood and subsequent suicidality, this systematic review examines the prevalence of, and association between the processes of humiliation and shame in later self-harm, suicidal ideation, and suicide among adolescents and young adults. METHODS: A systematic literature search of databases including MEDLINE, Web of Science Core Collection, CINAHL, PsycINFO, and Embase was conducted to identify potential studies. ProQuest was searched to identify relevant grey literature research. A combination of MESH terms and keywords was used. All original quantitative studies published in English that examined the prevalence, or association between humiliation or shame and suicidal behaviours and/or death by suicide were included. Studies were assessed for methodological quality using Joanna Briggs Institute critical appraisal tools. The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) [CRD42022289843]. RESULTS: Narrative synthesis was performed. A total of 33 studies reporting the prevalence of, or association between humiliation (n = 10) or shame (n = 23) and suicidal thoughts/behaviours were included. The prevalence of humiliation among those with any suicidality ranged from 18% to 28.1%, excluding an outlier (67.1%), with two studies presenting a significant association between humiliation and self-harm in their fully adjusted analyses. The studies that outlined humiliation and suicidal thinking (intent/suicide plan) had no association after adjustment for confounders. For shame, half of the studies found an association in adjusted models (n = 10), and this was evident for both suicidal ideation and self-harm. CONCLUSION: To our knowledge, this is the first study to attempt a systematic review on this topic. The dearth of research in this field of enquiry is reflective of unique challenges associated with assessments of humiliation and shame in various clinical settings amongst adolescent and young adult populations. Nonetheless, given the importance and relevance of the psychological imprint of humiliation in youth morbidity and mortality in the field of mental health, it is timely to attempt such a systematic review. In light of the associated role of humiliation and shame in self-harm and suicidality among young people, we recommend that these processes need to be explored further via prospective studies and assessed as part of a comprehensive bio-psycho-social assessment when focusing on life stressors for adolescent and young adults presenting with suicidality to emergency departments and mental health services.

Anomalous Flexor Digitorum Superficialis Muscle Belly Associated with Carpal Tunnel Syndrome.

Anomalous muscle bellies in the forearm generally are asymptomatic and appreciated in an academic sense during cadaveric dissections. Few prior anatomic variations in muscle bellies have been described with symptoms, and are associated even more rarely with carpal tunnel syndrome (CTS). We discuss the evaluation and management of a case of CTS associated with a muscle belly of the flexor digitorum superficialis to the index within the carpal tunnel.

Paraganglioma in a Young Adult Female Patient: A Case Report.

Paragangliomas are catecholamine-secreting neuroendocrine tumors that originate from the chromaffin cells of the sympathetic ganglia. Roughly 10% of paragangliomas are malignant, resulting in a rare occurrence of 90-95 cases per 400 million people. Herein, we report a case of a 29-year-old female patient who presented with nausea, vomiting, and bloating and was found to have a large left retroperitoneal tumor upon imaging. The tumor was successfully removed, and subsequent histological analysis was compatible with the presence of a paraganglioma. This case serves as a reminder that despite its rarity, paragangliomas should never be dismissed as a differential diagnosis if correlating symptoms and diagnostic findings are consistent with that of paraganglioma etiology.

Algorithms to Identify Nonmedical Opioid Use.

The rise in nonmedical opioid overdoses over the last two decades necessitates improved detection technologies. Manual opioid screening exams can exhibit excellent sensitivity for identifying the risk of opioid misuse but can be time-consuming. Algorithms can help doctors identify at-risk people. In the past, electronic health record (EHR)-based neural networks outperformed Drug Abuse Manual Screenings in sparse studies; however, recent data shows that it may perform as well or less than manual screenings. Herein, a discussion of several different manual screenings and recommendations is contained, along with suggestions for practice. A multi-algorithm approach using EHR yielded strong predictive values of opioid use disorder (OUD) over a large sample size. A POR (Proove Opiate Risk) algorithm provided a high sensitivity for categorizing the risk of opioid abuse within a small sample size. All established screening methods and algorithms reflected high sensitivity and positive predictive values. Neural networks based on EHR also showed significant effectiveness when corroborated with Drug Abuse Manual Screenings. This review highlights the potential of algorithms for reducing provider costs and improving the quality of care by identifying nonmedical opioid use (NMOU) and OUD. These tools can be combined with traditional clinical interviewing, and neural networks can be further refined while expanding EHR.

Atypical Imaging Findings of Nonketotic Hyperglycemic Hemichorea: A Case Report and Review of the Literature.

Nonketotic hyperglycemic hemichorea (NH-HC) is a rare condition presenting in the clinical setting. Brain imaging plays an important role in diagnosing NH-HC, which typically shows basal ganglia changes contralateral to the side of the hemiballismus/hemichorea. Only a few articles in the literature have reported normal pertinent magnetic resonance/CT findings in patients presenting with NH-HC. To the authors' knowledge, no cases in the literature have reported basal ganglia changes solely observed on CT but not on MRI in patients presenting with NH-HC. Herein, we describe a unique case in which a CT of a patient presenting with NH-HC demonstrated basal ganglia abnormalities with negative MRI findings.

Adrenal Ganglioneuroblastoma of Adult Onset: A Literature Review.

Ganglioneuroblastomas (GNBs) are a rare subtype of neoplastic tumors that arise from the autonomic nervous system and contain both mature gangliocytes and immature neuroblasts. The primary age group affected by GNBs is the pediatric population, with less than 50 cases of adult GNBs existing in the literature. To the authors' best knowledge, only 21 cases of GNBs arising in the adrenal glands of adults have been reported. Herein we present a literature review examining the symptoms, treatment type, age, and sex of adults, and the presence of tumor metastases and calcification from the 21 cases reported in the literature.

Hereditary Angioedema: Diagnosis, Clinical Implications, and Pathophysiology.

Hereditary angioedema (HAE) is an autosomal dominant disorder caused by a mutation in the C1 esterase inhibitor gene. HAE affects 1/50,000 people worldwide. Three main types of HAE exist: type I, type II, and type III. Type I is characterized by a deficiency in C1-INH. C1-INH is important in the coagulation complement, contact systems, and fibrinolysis. Most HAE cases are type I. Type I and II HAE result from a mutation in the SERPING1 gene, which encodes C1-INH. Formally known as type III HAE is typically an estrogen-dependent or hereditary angioedema with normal C1-INH activity. Current guidelines now recommend subdividing hereditary angioedema with normal C1 esterase inhibitor gene (HAE-nl-C1-INH formerly known as HAE type III) based on underlying mutations such as in kininogen-1 (HAE-KNG1), plasminogen gene (PLG-HAE), myoferlin gene mutation (MYOF-HAE), heparan sulfate-glucosamine 3-sulfotransferase 6 (HS3ST6), mutation in Hageman factor (factor XII), and in angiopoietin-1 (HAE-ANGPT-1). The clinical presentation of HAE varies between patients, but it usually presents with nonpitting angioedema and occasionally abdominal pain. Young children are typically asymptomatic. Those affected by HAE usually present with symptoms in their early 20s. Symptoms can arise as a result of stress, infection, or trauma. Laboratory testing shows abnormal levels of C1-INH and high levels of bradykinin. C4 and D-dimer levels can also be monitored if an acute HAE attack is suspected. Acute treatment of HAE can include IV infusions of C1-INH, receptor antagonists, and kallikrein inhibitors. Short- and long-term prophylaxis can also be administered to patients with HAE. First-line therapies for long-term prophylaxis also include IV infusion of C1-INH. This review aims to thoroughly understand HAE, its clinical presentation, and how to treat it.

GLP-1 Agonists for Weight Loss: Pharmacology and Clinical Implications.

This review investigates the various pharmacologic treatments for overweight and obesity in adults, especially glucagon-like peptide 1 (GLP-1) agonists. In light of the globally expanding obesity pandemic and the limited selection of treatments, physicians must be equipped with knowledge regarding proven medications and their nuanced differences to best support patients on their path to a healthier lifestyle. In this review, we explore the current medical therapies for obesity, including all major categories, individual mechanisms of action, pharmacokinetics and pharmacodynamics, adverse effects, risks, and absolute contraindications. Additionally, we review the evidence of four recent clinical trials, two systematic reviews, and two meta-analyses describing the efficacy of GLP-1 agonists in decreasing weight, lowering HbA1c, and improving obesity comorbidities. We also discuss total cost and cost-effectiveness compared to other categories, long-term adherence, barriers to use, and reasons for discontinuation of this drug category. Our goal is that this review can serve as a framework to aid providers in building their knowledge and selecting the most advantageous weight loss medication for each patient.

Helicobacter Pylori: A Review of Current Treatment Options in Clinical Practice.

BACKGROUND: When prescribing antibiotics, infection eradication rates, local resistance rates, and cost should be among the most essential considerations. Helicobacter pylori is among the most common infections worldwide, and it can lead to burdensome sequela for the patient and the healthcare system, without appropriate treatment. Due to constantly fluctuating resistance rates, regimens must be constantly assessed to ensure effectiveness. METHODS: This was a narrative review. The sources for this review are as follows: searching on PubMed, Google Scholar, Medline, and ScienceDirect; using keywords: Helicobacter pylori, Treatment Options, Clinical Practice. RESULTS: Multiple antibiotics are prescribed as part of the regimen to thwart high resistance rates. This can lead to unwanted adverse reactions and adherence issues, due to the amount and timing of medication administration, which also may contribute to resistance. Single-capsule combination capsules have reached the market to ease this concern, but brand-only may be problematic for patient affordability. Due to the previously mentioned factors, effectiveness and affordability must be equally considered. CONCLUSIONS: This review will utilize guidelines to discuss current treatment options and give cost considerations to elicit the most effective regimen for the patient.

Associations between humiliation, shame, self-harm and suicidal behaviours among adolescents and young adults: A systematic review protocol.

BACKGROUND: Suicide is the second leading cause of death among young people worldwide and remains a major public health concern. Research indicates that negative social contexts involving familial and peer relationships, have far-reaching influences on levels of suicidal behaviours in later life. Previous systematic reviews have focused on evaluating associations between negative life events such as abuse and bullying in childhood and subsequent self-harm or suicidality. However, the association between adolescent experiences of humiliation and shame, and subsequent self-harm or suicidal behaviour among children and young adults has not been well examined. As such, this systematic review is conducted to examine the prevalence and association between humiliation and shame and self-harm, suicidal ideation, and death by suicide among adolescents and young adults. METHODS: A systematic literature search in extant electronic databases including; MEDLINE, Web of Science Core Collection, CINAHL, PsycINFO, and Embase will be conducted to identify potential studies. Google Scholar, and the reference list of the retrieved articles and/or previous systematic reviews in this area, will also be scanned to identify further potential studies. ProQuest will be searched to identify relevant studies available within grey literature. There are no restrictions on the date of publications. Based on our initial review, the following terms were identified: Population: Adolescent (MESH), young adult (MESH), teen, teenage. Exposure: Humiliation, degradation, shame (MESH) or embarrassment (MESH), harassment victimisation, abasement. Outcome: Self-injurious behaviour (MESH), suicide (MESH), suicide attempted (MESH), suicide completed (MESH), self-harm, intentional self-injury, deliberate self-harm, overdose, deliberate self-poisoning, non-suicidal self-injury, self-mutilation, suicidal thought, suicidal ideation, suicidal intent, suicide. At least one term from each category will be used for conducting the literature search. All original quantitative studies published in the English language which examined the prevalence or association between humiliation or shame and self-harm and/or suicidal ideation and/or completed suicide will be included. The studies will be assessed for methodological quality using the Joanna Briggs Institute critical appraisal tools. Narrative synthesis will be performed for all of the studies. If the studies are sufficiently homogenous, the results will be pooled for a meta-analysis. This systematic review protocol followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P) guidelines. The protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO) [CRD42022289843]. DISCUSSION: This is the first review to synthesise evidence on the prevalence of, and associations between the experiences of humiliation and shame and subsequent self-harm and/or suicidal behaviours among adolescents and young adults. As there is growing evidence on increased self-harm among this age group, it is important to identify population-specific risk factors for self-harm and suicidality which will have significance in formulating tailored and effective treatment and therapeutic services for adolescents and young adults.

Amniotic Membrane Scaffolds Support Organized Muscle Regeneration in A Murine Volumetric Muscle Defect Model.

Current treatment for volumetric muscle loss is limited to muscle transfer or acellular collagen scaffold (ACS) therapies that are associated with donor site morbidity and nonfunctional fibrosis, respectively. The aim of this study is to assess the utility of amniotic membrane scaffold (AMS) for volumetric muscle loss treatment. Methods: Murine quadriceps defects were created and randomized to three groups (n = 5/group): untreated controls, ACS, and AMS. In vivo muscle regeneration volume was quantified by MRI and microcomputed tomography. Muscle explants were analyzed using standard histology and whole-mount immunofluorescence at 8 weeks. Results: The cross-sectional muscle regeneration ratio was 0.64 ± 0.3 for AMS, 0.48 ± 0.07 for ACS, and 0.4 0 ± 0.03 for controls as assessed by MRI (P = 0.09) and 0.61 ± 0.28 for AMS, 0.50 ± 0.06 for ACS, and 0.43 ± 0.04 for controls as assessed by microcomputed tomography (P = 0.2). Histologically, AMS demonstrated significantly higher cellular density (900 ± 2 70 nuclei/high powered field) than ACS (210 ± 36) and control (130 ± 4) groups (P = 0.05). Immunofluorescence for laminin (AMS 623 ± 11 versus ACS 339 ± 3 versus control 115 ± 7; P < 0.01) and myosin heavy chain (AMS 509 ± 7 versus ACS 288 ± 5 versus control 84 ± 5; P = 0.03) indicated greater organized muscle fiber formation with AMS. Conclusion: AMS mediated muscle healing was characterized by increased cellular infiltration and organized muscle formation when compared with controls and ACS.

Successful Treatment of Catatonia: A Case Report and Review of Treatment.

Herein, we report the case of a 20-year-old Caucasian male with a previous psychiatric history of schizophreniform, autism, unspecified intellectual disorder, and past medical history of hypertension, who presented after a suicidal attempt. One month prior to admission for the suicidal attempt, the patient had mutism. While admitted, the patient showed signs of mutism, posturing, negativism, and waxy flexibility. Treatment with both aripiprazole and lorazepam was effective and reversed the patient's catatonia after low-dose titration. This case highlights the importance of reviewing patient history and presenting symptoms in the management of catatonia. Additionally, this case provides an opportunity to review the diagnostic approach and treatment type used for patients presenting with catatonia.

In an Emergency Setting, What Is the Best Intramuscular Pharmacological Treatment to Give to an Agitated Geriatric Patient?

Herein, we describe an agitated geriatric patient who suffered an adverse outcome due to treatment for agitation in an emergency setting. This led to the prompt review of the current literature on best-practice medication to use in this population. After careful review, the authors recommend olanzapine as the first-line medication for agitation due to its lower risk-averse effect profile when compared to other medications used for this patient population.

Does Time to Operative Intervention of Distal Radius Fractures Influence Outcomes?

BACKGROUND: No investigation has analyzed the time from injury to operative intervention and its effect on complications and functional outcomes in distal radius fractures. This investigation aimed to establish whether the time to surgical intervention from injury was associated with the observed rate of complications in distal radius fractures. METHODS: A retrospective review of all orthopedic trauma patients who came to our center was conducted from 2008 through 2014. Patients who sustained closed distal radius fractures were included. A postoperative complication following distal radius fracture was defined as reoperation, superficial or deep infection, complex regional pain syndrome, new-onset carpal tunnel syndrome, tendon irritation, and symptomatic hardware. RESULTS: In all, 190 patients were included in the study with a mean age of 48 years (SD ±14.7). According to the AO-Müller/Orthopaedic Trauma Association classification, radiographs revealed 80 A fractures, 15 B fractures, and 95 C fractures. Thirty distal radii were fixed within 0 to 3 days after injury, 91 patients within 4 to 10 days, and 69 patients after 10 days. Overall, 28 complications (14.7%) were identified. There was no statistical difference in the rate of complications between the time interval groups (P = .17). CONCLUSIONS: Despite the increased popularity of surgical intervention for distal radius fractures, the optimal parameters to maximize patient outcomes have yet to be clearly defined. Time to intervention did not affect the rate of postoperative complication and range of motion.

A Primer and Literature Review on Internal and External Retention Mechanisms for Catheter Fixation.

Although catheters are commonplace in hospital settings, there is scarce literature discussing the internal and external retention mechanisms used to aid in catheter fixation. Additionally, exact definitions and detailed information on internal and external retention mechanisms are almost non-existent in the literature. This article serves three primary purposes. The first purpose is to define internal and external catheter retention mechanisms, describe how they work, and provide examples of each that are routinely used in healthcare settings. The second goal of this paper is to provide a literature review comparing various aspects of the different types of internal and external catheter retention mechanisms discussed in the paper, including performance variance and the advantages and disadvantages of each. The third aim of this article is to provide a brief overview of catheter dislodgment, including the rates at which this occurs, the problems that can arise, and the best treatment option when this does occur.

A Sleeve-Sheath With a Coaxial Exchangeable Catheter for Palliative Evacuation of Recurrent Thoracic and Abdominal Effusions.

Herein we describe an outer cannula sleeve-sheath with a coaxially inserted exchangeable drainage catheter (SCDC) for effective evacuation of recurrent symptomatic fluid collections in the thorax and abdomen on patients in lieu of, or failed, current evacuation catheters and methods. The design is an alternative to existing commercially available devices and adds distinct enhancements with the possibility of intrathoracic or intrabdominal trans outer sleeve-sheath diagnostic or therapeutic interventions. This device aims at requiring a single invasive procedure (thoracentesis and paracentesis) while offering catheter exchange and repositioning if malfunction or malposition occurs during the patient's lifetime. The SCDC outer sheath in the subcutaneous tissues of the thorax or abdomen has built-in two antibacterial cuffs to prevent infection. At the same time, the exchangeable coaxially inserted drainage catheter is deployed over a guidewire within the thoracic or abdominal cavities. The drainage catheter has a fluid dynamic proven efficient design to facilitate drainage and can recanalize its lumen if occluded by fibrin or tissue.

Preoperative Embolization of a Delayed Femoral Metastasis of Renal Cell Carcinoma: A Case Report.

Preoperative embolization of hypervascular bone metastasis is an effective measure for reducing blood loss during open orthopedic surgery. When the clinician is experienced with the procedure, the risks of the procedure are minimal and final outcomes are typically good. In this study, we report a case of a 50-year-old female patient who presented with a delayed metastatic renal cell tumor in the left proximal femur one year after radical nephrectomy. The patient underwent an effective preoperative embolization, which resulted in a remarkable absence of bleeding and a successful response subsequent to surgical fixation.

An Atypical Presentation of West Nile Virus With Successful Treatment After Plasma Exchange and Intravenous Immunoglobulin.

West Nile (WN) disease is a relatively rare arboviral virus. Neuroinvasive cases of WN account for less than 1% of the total cases. The case described had difficult symptomatology and radical presentation, which included ascending paralysis. To date, there have been very few reports of West Nile cases that present with ascending paralysis. We describe the case of a 63-year-old white male who presented with a fever and proximal muscle weakness in the thighs and legs that rapidly worsened and ascended, eventually resulting in diaphragmatic paralysis. He was intubated after respiratory failure and given intravenous immunoglobulin and plasma exchange. The patient remained ventilated with persistent weakness. However, this improved after intravenous immunoglobulin and plasma exchange therapy. This case serves as a reminder to keep the diagnosis of WN on the differential, a primer on advanced treatments in the setting of aggressive atypical WN, and a lesson on similarly presenting diseases and distinguishing characteristics that may help rule out these diseases from WN.
