[Foot and ankle pathologies during pregnancy]. / Pathologies du pied et de la cheville pendant la grossesse.

Foot and ankle pain and oedema are a common complaint among pregnant women. A range of hormonal and anatomical changes during pregnancy can cause modifications in foot and ankle's biomechanics and anatomy. The main foot and ankle pathologies encountered in pregnancy are progressive collapsing foot deformity, plantar fasciitis, heel pain, oedema, and fractures. Workup includes the use of radiological evaluation that could pose a risk to the fetus, depending on the gestational age. Treatment plans range from symptomatic conservative to surgical options and a multidisciplinary approach is often recommended and warranted. Our paper aims to present these different pathologies and propose a structured treatment plan to address them.

La douleur et l'œdème du pied et de la cheville sont fréquents chez les femmes enceintes. Plusieurs changements hormonaux et anatomiques pendant la grossesse entraînent des modifications dans la biomécanique et l'anatomie du pied et de la cheville. Les pathologies les plus fréquentes concernant cette localisation rencontrées pendant la grossesse sont le pied plat progressif, la fasciite plantaire, la douleur au talon, l'œdème et les fractures. Le bilan demande souvent une évaluation radiologique pouvant présenter un risque pour le fœtus, en fonction de l'âge gestationnel. Les plans de traitement vont du traitement conservateur à la chirurgie et une approche multidisciplinaire est souvent recommandée et justifiée. Cet article présente ces différentes pathologies et propose un plan de traitement structuré.

Anti-interleukin-6 receptor antibody for the treatment of remitting seronegative symmetrical synovitis with pitting oedema: a new outlook?

We present the case of an elderly man with a small-joint polyarthritis, accompanied by pitting oedema, involving hands and feet, raising clinical suspicion of remitting seronegative symmetrical synovitis with pitting oedema (RS3PE). Treatment with corticosteroids was initiated with significant improvement, but unacceptable iatrogeny ensued, and tapering was not possible without disease flare-up. A trial of tocilizumab allowed disease activity control, slow weaning of corticosteroids and, ultimately, its suspension. RS3PE is a rare rheumatological entity, initially thought to be a variant of rheumatoid arthritis (RA), with shared traits with polymyalgia rheumatica (PMR), and other seronegative spondyloarthropathies, thereby implying a shared pathophysiological background. Elevated levels of interleukin 6 (IL-6) are found in patients with RA, have shown to mirror disease activity in PMR and have also been described in the serum and synovial fluid of patients with RS3PE. Tocilizumab, an anti-IL-6 receptor antibody, shows auspicious results in several other rare rheumatic diseases other than RA.

Use of compression therapy for cellulitis.

INTRODUCTION: Cellulitis is a common infection, especially among the elderly, and compression therapy is often recommended to reduce acute oedema and pain. A previous study showed that compression therapy led to a lower incidence of recurrent cellulitis in lower extremities in patients with chronic oedema. The aim of this study was to describe clinical characteristics of patients with cellulitis. METHODS: This was a retrospective descriptive study reviewing medical records and medicine registrations in patients ≥ 18 years with cellulitis. RESULTS: A total of 104 patients were hospitalised with cellulitis; 13 were excluded. The median age was 75 years (range: 33-103 years), 64% > 70 years. The median admission time was five days (range: 1-24 days). Median antibiotic treatment duration was 11 days (range: 4-56 days). A total of 45% were current or former smokers, 40% were overweight, 48% had preexisting chronic oedema of the affected area, 90% had become infected in the lower extremities and 19% were readmitted within six months. A total of 51% had a new antibiotic treatment prescribed after being discharged, and 66% received compression therapy. CONCLUSIONS: Cellulitis frequently affects older patients, especially smokers, people with overweight and chronic lymphoedema. In all, 66% were treated with compression therapy that did not have a clear effect on their readmission rate, probably because the patients receiving compression therapy had a more severe infection complicated by severe oedema and a higher risk of reinfection. An increased focus on the use of compression therapy in conjunction with health preventive interventions may have a positive impact on the relapse rate. FUNDING: None.

Differences in risk profile associated with varicose veins and chronic venous insufficiency - results from the Bonn Vein Study 1.

Background: The aim of this publication is to demonstrate similarities and differences in the association of risk factors with the prevalence of different manifestations of chronic venous disease (CVD), like varicose veins (VV), venous oedema (C3) and severe chronic venous insufficiency (CVI) in the population-based cross-sectional Bonn Vein Study 1 (BVS). Patients and methods: In the BVS 1 between 13.11.2000 and 15.3.2002, 3.072 participants, 1350 men and 1722 women, from a simple random sample of the general population of the city of Bonn and two rural townships aged 18-79 years were included. The overall response proportion was 59%. All participants answered a standardized questionnaire including information about socio-economic data, lifestyle, physical activity, medical history, and quality of life. Venous investigations were performed clinically and by a standardized duplex examination by trained investigators. The CEAP classification in the version of 1996 was used to classify the findings. Logistic regression models were performed for the association of possible risk factors with VV, venous edema (C3) and severe CVI (C4-C6). The predictive risk (PR) describes the association of the diseases and the possible influencing factors. Results: VV, venous oedema (C3) and severe CVI (C4-C6) have common risk factors like higher age, number of pregnancies, family history of VV and overweight or obesity. Female gender is significantly associated with VV and C3 but not with severe CVI (C4-C6). High blood pressure and urban living are only associated with C3 and C4-C6 disease whereas prolonged sitting is associated with C3 and lower social class with C4-C6 exclusively. Discussion: In many epidemiological studies risk factors were associated with chronic venous disorders in general. Our data show that VV, venous edema and severe CVI may have different risk profiles. Venous edema is more often associated with arterial hypertension and sedentary lifestyle whereas lower social class seems to be a risk factor for severe CVI including venous ulcers. Conclusions: The differences in the association of risk factors to VV, venous edema and severe CVI should be considered if prevention and treatment of chronic venous diseases are planned. As examples, compression stockings could be proposed in sitting profession to prevent oedema, VV patients with risk factors like obesity might benefit from early treatment for VV and obesity. More longitudinal evaluation of risk factors is necessary to evaluate the true risk profile of CVD.

Exogenous Peptide Injection Causing Medical Thigh Compartment Syndrome.

BACKGROUND: Acute compartment syndrome can be caused by any condition that increases the pressure of an intracompartmental muscular space, resulting in ischemia, which is a limb-threatening emergency. This case report is the first known documented example of an exogenously injected peptide causing compartment syndrome. The use of natural supplements and holistic therapies is on the rise, specifically, peptide injections. It is important to obtain the history of use and routes of administration of these substances. CASE REPORT: We present a case of a 43-year-old man who presented to the Emergency Department with worsening thigh pain. The patient had injected a "peptide cocktail" into his thigh 3 days prior. Physical examination revealed trace pitting edema of the left leg with moderate muscle spasm and tenderness of the medial aspect of the distal thigh with associated numbness along the medial aspect of the knee. Point-of-care ultrasound detected intramuscular edema and free fluid in the leg. He was found to have acute compartment syndrome of the thigh secondary to the peptide cocktail injection, causing a large hematoma posterior to the adductor magnus. The patient required fasciotomy and hematoma evacuation. He ultimately left against medical advice during his hospitalization. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In an age when many patients look for supplements to aid with weight loss and muscle growth, it is essential to be aware of peptide injection therapies and the potential complication of compartment syndrome.

If not angioedema, what is it? Diagnostic approach to facial edema.

Facial edema is a relatively frequent clinical presentation encountered in patients seen in allergology and dermatology clinics. The differential diagnosis is broad, and sometimes the definitive diagnosis can be a challenge for the clinician. Facial angioedema itself encompasses different etiopathologies (histaminergic, bradykinergic, etc.) that must be distinguished from other causes of facial edema, such as allergic contact dermatitis, granulomatous conditions, inflammatory causes, infections, neoplasms or paraneoplastic syndromes, autoimmune diseases, among other entities hereby referred as miscellanea. A proper diagnostic approach is essential to order the appropriate tests, as well as to prescribe a targeted treatment. This review focuses on entities that present with facial edema and summarize their characteristic clinical features.

Optical coherence tomographic features of feline acute corneal hydrops: A case report.

OBJECTIVE: The objective of the study was to describe the optical coherence tomographic features of a cat with acute corneal hydrops. ANIMAL STUDIED: A 4-year-old castrated male domestic shorthaired showing conjunctival redness, ocular discharge, and intermittent squinting of both eyes with asymmetrical disease onset. METHODS: Complete ophthalmic examination and optical coherence tomography were performed. RESULTS: On slit-lamp biomicroscopic examination, severe intrastromal fluid pockets with profound bullae were observed in the dorsomedial region in both eyes. A diagnosis of feline acute corneal hydrops was made in both eyes. Optical coherence tomography revealed profound stromal lamellar separation representing heterogeneous reflective areas, and fluid pockets and bullae of variable size were concomitant to Descemet's membrane detachment demonstrated by a well-defined homogeneous hyporeflective area. Upon reevaluation 30 days during healing process for both eyes, the thickened epithelia and the thinning pan-stromal areas were identified as homogeneously hyper-reflective epithelia and as heterogeneous hyper-reflectivity, respectively. A thickened posterior corneal surface was shown as heterogeneous with patchy hyper-reflectivity. Additionally, Descemet's membrane detachment in the initial presentation had two distinct forms suspicious of Descemet's membrane rupture in each eye: a break with rolled ends and a break with flat ends. CONCLUSION: To the author's knowledge, this study represents the first documentation of in vivo detection of Descemet's membrane detachment and presumed rupture in a cat experiencing acute corneal hydrops. These observations strongly indicate that Descemet's membrane detachment/rupture acts as a most likely risk factor in the onset of acute corneal hydrops in cats.

Cochlear Otosclerosis and Secondary Hydrops (Ménière's Syndrome).

ABSTRACT: This article discusses a case of cochlear otosclerosis leading to secondary hydrops and near-complete hearing loss. Histopathological examination revealed advanced multifocal otosclerosis in both temporal bones, with specific focus on cochlear invasion and significant bone resorption. The severity of the case ruled out surgical intervention due to the risk of further hearing loss. The article emphasizes the challenges in managing otosclerosis-related hydrops and highlights the potential use of advanced imaging techniques for diagnosis. The study underscores the complexity of otosclerosis-induced hearing loss, contributing to the understanding of this pathology and its impact on auditory function.

Metabolic acidemia due to saline absorption during transurethral and transcervical surgery: a report of 2 cases.

BACKGROUND: The development of endoscopic systems that include bipolar electrocautery has enabled the use of normal saline irrigation in transurethral or transcervical endoscopic surgery. However, excessive saline absorption can cause hyperchloremic metabolic acidosis. CASE PRESENTATION: Patient 1: A 76-year-old man was scheduled for transurethral resection of the prostate with saline irrigation. Approximately 140 min after the surgery, abdominal distension and cervical edema were observed. Abdominal ultrasound examination indicated a subhepatic hypoechoic lesion, which suggested extravasation of saline. Arterial blood gas analysis revealed hyperchloremic metabolic acidosis. The patient was extubated 2 h after the operation with no subsequent airway problems, and the electrolyte imbalance was gradually corrected. Patient 2: A 43-year-old woman was scheduled for transcervical resection of a uterine fibroid with saline irrigation. When the drape was removed after the operation was finished, notable upper extremity edema was observed. Arterial blood gas analysis revealed hyperchloremic metabolic acidosis. The patient's acidemia, electrolyte imbalance, and neck edema gradually resolved, and the patient was extubated 16 h after the operation without subsequent airway problems. CONCLUSIONS: Anesthesiologists should be aware of acidemia, cardiopulmonary complications, and airway obstruction caused by excessive saline absorption after saline irrigation in endoscopic surgery.

Management of hepatic hydropericardium with open drainage, maximal medical therapy and terlipressin.

We present the case of a woman in her 60s with Child-Pugh C cirrhosis who developed pericardial tamponade during an admission for a haemothorax secondary to a mechanical fall. The patient developed haemodynamic compromise with a rapid decline in renal function. During an open subxiphoid drain tube insertion, a pre-existing peritoneopericardial communication was noted, with ascites in the peritoneal cavity on view. The serum ascites albumin gradient was 14 g/L. Maximal medical therapy was commenced including diuresis and albumin, with adjunctive terlipressin infusion which restored her baseline renal function and resolved the effusion. We believe this is the first case report of using open drainage, maximal medical therapy and terlipressin to successfully treat hepatic hydropericardium and its subsequent renal compromise.

A new lymphedema treatment using pyro-drive jet injection.

Lymphedema, resulting from impaired lymphatic drainage, causes inflammation, fibrosis and tissue damage leading to symptoms such as limb swelling and restricted mobility. Despite various treatments under exploration, no standard effective therapy exists. Here a novel technique using the pyro-drive jet injection (PJI) was used to create artificial clefts between collagen fibers, which facilitated the removal of excess interstitial fluid. The PJI was used to deliver a mixture of lactated Ringer's solution and air into the tail of animals with secondary skin edema. Edema levels were assessed using micro-CT scanning. Histopathological changes and neovascularization were evaluated on the injury-induced regenerative tissue. Regarding tissue remodeling, we focused on connective tissue growth factor (CTGF) and vascular endothelial growth factor (VEGF)-C. PJI markedly diminished soft tissue volume in the experimental lymphedema animals compared to the non-injected counterparts. The PJI groups exhibited a significantly reduced proportion of inflammatory granulation tissue and an enhanced density of lymphatic vessels and α-smooth muscle actin (αSMA)-positive small vessels in the fibrous granulation tissue compared to the controls. In addition, PJI curtailed the prevalence of CTGF- and VEGF-C-positive cells in regenerative tissue. In a lymphedema animal model, PJI notably ameliorated interstitial edema, promoted lymphatic vessel growth, and bolstered αSMA-positive capillaries in fibrous granulation tissue. PJI's minimal tissue impact post-lymph node dissection indicates significant potential as an early, standard preventative measure. Easily applied in general clinics without requiring specialized training, it offers a cost-effective and highly versatile solution to the management of lymphedema.

Factors associated with cellulitis in lymphoedema of the arm - an international cross-sectional study (LIMPRINT).

BACKGROUND: Lymphoedema is a globally neglected health care problem and a common complication following breast cancer treatment. Lymphoedema is a well-known predisposing factor for cellulitis, but few have investigated the risk factors for cellulitis in this patient cohort on an international level. The aim of this study was to identify the frequency of cellulitis in patients with lymphoedema of the arm, including potential risk factors for cellulitis. METHODS: An international, multi-centre, cross-sectional study including patients with clinically assessed arm lymphoedema. The primary outcome was the incidence of cellulitis located to the arm with lymphoedema within the last 12 months, and its potential associated risk factors. The secondary outcome was life-time prevalence of cellulitis. Adults with clinically-assessed arm lymphoedema/chronic oedema (all causes) and able to give informed consent were included. End-of-life-patients or those judged as not in the patient's best interest were excluded. Both univariable and multivariable analysis were performed. RESULTS: A total of 2160 patients were included from Australia, Denmark, France, Ireland, Italy, Japan, Turkey and United Kingdom. Secondary lymphoedema was present in 98% of the patients; 95% of these were judged as related to cancer or its treatment. The lifetime prevalence of cellulitis was 22% and 1-year incidence 11%. Following multivariable analysis, factors associated with recent cellulitis were longer swelling duration and having poorly controlled lymphoedema. Compared to having lymphoedema less than 1 year, the risk increased with duration: 1-2 years (OR 2.15), 2-5 years (OR 2.86), 5-10 years (OR 3.15). Patients with well-controlled lymphoedema had a 46% lower risk of cellulitis (OR 0.54, 95% CI 0.39-0.73, p < 0.001). More advanced stages of lymphoedema were associated with cellulitis even after adjustment for swelling duration and control of swelling by logistic regression (stage II OR 5.44, stage III OR 9.13, p = 0.002), demonstrated in a subgroup analysis. CONCLUSION: Patients with advanced arm lymphoedema are at particular risk of developing cellulitis. Prevention of lymphoedema progression is crucial. The results lend towards a positive effect of having well-treated lymphoedema on the frequency of cellulitis.

CSF-Based Volumetric Imaging Biomarkers Highlight Incidence and Risk Factors for Cerebral Edema After Ischemic Stroke.

BACKGROUND: Cerebral edema has primarily been studied using midline shift or clinical deterioration as end points, which only captures the severe and delayed manifestations of a process affecting many patients with stroke. Quantitative imaging biomarkers that measure edema severity across the entire spectrum could improve its early detection, as well as identify relevant mediators of this important stroke complication. METHODS: We applied an automated image analysis pipeline to measure the displacement of cerebrospinal fluid (ΔCSF) and the ratio of lesional versus contralateral hemispheric cerebrospinal fluid (CSF) volume (CSF ratio) in a cohort of 935 patients with hemispheric stroke with follow-up computed tomography scans taken a median of 26 h (interquartile range 24-31) after stroke onset. We determined diagnostic thresholds based on comparison to those without any visible edema. We modeled baseline clinical and radiographic variables against each edema biomarker and assessed how each biomarker was associated with stroke outcome (modified Rankin Scale at 90 days). RESULTS: The displacement of CSF and CSF ratio were correlated with midline shift (r = 0.52 and - 0.74, p < 0.0001) but exhibited broader ranges. A ΔCSF of greater than 14% or a CSF ratio below 0.90 identified those with visible edema: more than half of the patients with stroke met these criteria, compared with only 14% who had midline shift at 24 h. Predictors of edema across all biomarkers included a higher National Institutes of Health Stroke Scale score, a lower Alberta Stroke Program Early CT score, and lower baseline CSF volume. A history of hypertension and diabetes (but not acute hyperglycemia) predicted greater ΔCSF but not midline shift. Both ΔCSF and a lower CSF ratio were associated with worse outcome, adjusting for age, National Institutes of Health Stroke Scale score, and Alberta Stroke Program Early CT score (odds ratio 1.7, 95% confidence interval 1.3-2.2 per 21% ΔCSF). CONCLUSIONS: Cerebral edema can be measured in a majority of patients with stroke on follow-up computed tomography using volumetric biomarkers evaluating CSF shifts, including in many without visible midline shift. Edema formation is influenced by clinical and radiographic stroke severity but also by chronic vascular risk factors and contributes to worse stroke outcomes.

Photobiomodulation Therapy to Treat Snakebites Caused by Bothrops atrox: A Randomized Clinical Trial.

Importance: Bothrops venom acts almost immediately at the bite site and causes tissue damage. Objective: To investigate the feasibility and explore the safety and efficacy of low-level laser therapy (LLLT) in reducing the local manifestations of B atrox envenomations. Design, Setting, and Participants: This was a double-blind randomized clinical trial conducted at Fundação de Medicina Tropical Doutor Heitor Vieira Dourado, in Manaus, Brazil. A total of 60 adult participants were included from November 2020 to March 2022, with 30 in each group. Baseline characteristics on admission were similarly distributed between groups. Data analysis was performed from August to December 2022. Intervention: The intervention group received LLLT combined with regular antivenom treatment. The laser used was a gallium arsenide laser with 4 infrared laser emitters and 4 red laser emitters, 4 J/cm2 for 40 seconds at each application point. Main Outcomes and Measures: Feasibility was assessed by eligibility, recruitment, and retention rates; protocol fidelity; and patients' acceptability. The primary efficacy outcome of this study was myolysis estimated by the value of creatine kinase (U/L) on the third day of follow-up. Secondary efficacy outcomes were (1) pain intensity, (2) circumference measurement ratio, (3) extent of edema, (4) difference between the bite site temperature and that of the contralateral limb, (5) need for the use of analgesics, (6) frequency of secondary infections, and (7) necrosis. These outcomes were measured 48 hours after admission. Disability assessment was carried out from 4 to 6 months after patients' discharge. P values for outcomes were adjusted with Bonferroni correction. Results: A total of 60 patients (mean [SD] age, 43.2 [15.3] years; 8 female individuals [13%] and 52 male individuals [87%]) were included. The study was feasible, and patient retention and acceptability were high. Creatine kinase was significantly lower in the LLLT group (mean [SD], 163.7 [160.0] U/L) 48 hours after admission in relation to the comparator (412.4 [441.3] U/L) (P = .03). Mean (SD) pain intensity (2.9 [2.7] vs 5.0 [2.4]; P = .004), circumference measurement ratio (6.6% [6.6%] vs 17.1% [11.6%]; P < .001), and edema extent (25.8 [15.0] vs 40.1 [22.7] cm; P = .002) were significantly lower in the LLLT group in relation to the comparator. No difference was observed between the groups regarding the mean difference between the bite site temperature and the contralateral limb. Secondary infections, necrosis, disability outcomes, and the frequency of need for analgesics were similar in both groups. No adverse event was observed. Conclusions and Relevance: The data from this randomized clinical trial suggest that the use of LLLT was feasible and safe in a hospital setting and effective in reducing muscle damage and the local inflammatory process caused by B atrox envenomations.

Analysis of brain edema in RHAPSODY.

BACKGROUND: Cerebral edema is a secondary complication of acute ischemic stroke, but its time course and imaging markers are not fully understood. Recently, net water uptake (NWU) has been proposed as a novel marker of edema. AIMS: Studying the RHAPSODY trial cohort, we sought to characterize the time course of edema and test the hypothesis that NWU provides distinct information when added to traditional markers of cerebral edema after stroke by examining its association with other markers. METHODS: A total of 65 patients had measurable supratentorial ischemic lesions. Patients underwent head computed tomography (CT), brain magnetic resonance imaging (MRI) scans, or both at the baseline visit and after 2, 7, 30, and 90 days following enrollment. CT and MRI scans were used to measure four imaging markers of edema: midline shift (MLS), hemisphere volume ratio (HVR), cerebrospinal fluid (CSF) volume, and NWU using semi-quantitative threshold analysis. Trajectories of the markers were summarized, as available. Correlations of the markers of edema were computed and the markers compared by clinical outcome. Regression models were used to examine the effect of 3K3A-activated protein C (APC) treatment. RESULTS: Two measures of mass effect, MLS and HVR, could be measured on all imaging modalities, and had values available across all time points. Accordingly, mass effect reached a maximum level by day 7, normalized by day 30, and then reversed by day 90 for both measures. In the first 2 days after stroke, the change in CSF volume was associated with MLS (ρ = -0.57, p = 0.0001) and HVR (ρ = -0.66, p < 0.0001). In contrast, the change in NWU was not associated with the other imaging markers (all p ⩾ 0.49). While being directionally consistent, we did not observe a difference in the edema markers by clinical outcome. In addition, baseline stroke volume was associated with all markers (MLS (p < 0.001), HVR (p < 0.001), change in CSF volume (p = 0.003)) with the exception of NWU (p = 0.5). Exploratory analysis did not reveal a difference in cerebral edema markers by treatment arm. CONCLUSIONS: Existing cerebral edema imaging markers potentially describe two distinct processes, including lesional water concentration (i.e. NWU) and mass effect (MLS, HVR, and CSF volume). These two types of imaging markers may represent distinct aspects of cerebral edema, which could be useful for future trials targeting this process.

T1-VIBE and STIR MRI of lumbar pars interarticularis injuries in elite athletes: fracture characterisation and potential prognostic indicators.

OBJECTIVES: To assess how pars interarticularis fracture characteristics on T1-VIBE and STIR MRI relate to healing and identify anatomical parameters that may impact healing. MATERIALS AND METHODS: A retrospective review of an MRI series of lumbar pars interarticularis injuries in elite athletes over a 3-year period. Fracture configurations, signal intensities and anatomical parameters were recorded by two radiologists. Statistical analysis employed multilevel mixed-effects linear regressions, adjusted for repeated measures and baseline covariates. RESULTS: Forty-seven lumbar pars interarticularis injuries among 31 athletes were assessed. On final scans for each athlete, 15% (7/47) injuries had worsened, 23% (11/47) remained stable, 43% (20/47) partially healed and 19% (9/47) healed completely. Healing times varied, quickest was 49 days for a chronic fracture in a footballer. Bone marrow oedema signal was highest in worsened fractures, followed by improved, and lowest in stable fractures. As healing progressed, T1-VIBE signal at the fracture line decreased. Bone marrow oedema and fracture line signal peaked at 90-120 days before decreasing until 210-240 days. Fractures with smaller dimensions, more vertical orientation and a longer superior articular facet beneath were significantly associated with better healing (p < 0.05). CONCLUSION: Most diagnosed athletic pars interarticularis injuries improve. Normalising T1-VIBE signal at the fracture line is a novel measurable indicator of bony healing. Contrastingly, bone marrow oedema signal is higher in active fractures irrespective of healing or deterioration. Injuries initially perceived as worsening may be exhibiting the normal osteoclastic phase of healing. Better outcomes favour smaller, vertical fractures with a longer superior articular facet beneath.

Superior vena cava syndrome in chronic intestinal failure patients: When the going gets tough.

BACKGROUND & AIMS: Catheter-related venous thrombosis is a severe complication of home parenteral nutrition (HPN) with potentially devastating consequences such as superior vena cava syndrome (SVCS). Early recognition and awareness of factors leading to its development are of paramount importance. However, studies are lacking in HPN patients focusing on this topic. In this study, we aimed to determine the incidence of SVCS in HPN patients and describe SVCS-related outcomes. METHODS: This retrospective cohort study comprised all adult HPN patients who developed SVCS between 2000 and 2022 at our national HPN referral center. Primary outcome was the incidence of SVCS. Secondary outcomes include SVCS-related symptoms, tip location of central venous access device (CVAD) post-insertion and at time of SVCS, diagnostics and treatment. RESULTS: SVCS was diagnosed in 38 of 616 patients (6%), with an annual cumulative incidence rate ranging between 0 and 4.2%. Most common presenting symptoms were facial edema (82%) and arm edema (50%). Post-insertion, 17% (6/36) of patients had a correct position of the CVAD tip and 11% (4/36) during SVCS diagnosis. Computed tomography was the most used diagnostic imaging technique (66%). Sixty-three percent of patients started, 11% switched, and 21% continued anticoagulant treatment. CONCLUSIONS: The incidence of SVCS is relatively high in our vulnerable HPN population. It is key to recognize whenever such patients present with vascular obstruction-related symptoms and treat them in an early stage by a multidisciplinary team.

Association of anatomical variants of the sacroiliac joint with bone marrow edema in patients with axial spondyloarthritis.

OBJECTIVE: To determine the prevalence of sacroiliac joint variants in patients with axial spondyloarthritis (axSpA) using MRI-based synthetic CT images and to evaluate their relationships with the presence of bone marrow edema, as this may potentially complicate diagnosing active sacroiliitis on MRI in patients with suspected axSpA. METHODS: 172 patients were retrospectively included. All patients underwent MRI because of clinical suspicion of sacroiliitis. The diagnosis of axSpA was made by a tertiary hospital rheumatologist. Two readers independently determined the presence of bone marrow edema and the presence of one or more of the nine known sacroiliac joint (SIJ) variants. RESULTS: SIJ variants were common in axSpA patients (82.9%) and the non-SpA group (85.4%); there were no significant differences in prevalence. Bone marrow edema was frequently found in axSpA (86.8%) and non-SpA patients (34%). AxSpA patients with SIJ variants (except for accessory joint) demonstrated 4 to 10 times higher odds for bone marrow edema, however not statistically significant. The more variants were present in this group, the higher the chance of bone marrow edema. However, some multicollinearity cannot be excluded, since bone marrow edema is very frequent in the axSpA group by definition. CONCLUSION: SIJ variants are common in axSpA and non-SpA patients. SIJ variants were associated with higher prevalence of bone marrow edema in axSpA patients, potentially due to altered biomechanics, except for accessory joint which may act as a stabilizer.

Repeated Acute Exacerbations of Chronic Inflammatory Demyelinating Polyradiculoneuropathy Accompanied by Pain and Swelling in Distal Extremities.

An 81-year-old man experienced acute progression of weakness in the extremities accompanied by a fever, tenderness, and swelling in distal parts of the extremities. He had flaccid tetraparesis with fasciculations and general hyporeflexia. Nerve conduction studies indicated demyelinating sensorimotor neuropathy. A cerebrospinal fluid examination revealed elevated proteins without pleocytosis. Immunological treatments were effective, but his symptoms exhibited repeated relapse and remission phases. He was diagnosed with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with an acute onset. The highlight of this case is pain with inflammatory reaction recognized as red flags of CIDP, with the clinical course and electrophysiological findings compatible with CIDP.

Complications of the Superior Eyelid Endoscopic Transorbital Approach to the Skull Base: Preliminary Experience With Specific Focus on Orbital Outcome.

BACKGROUND: The endoscopic superior eyelid approach is a relatively novel mini-invasive technique that is currently investigating for skull base cancers. However, questions remain regarding specific approach-related complications when treating different skull base tumors. This study aims to analyze any surgical complications that occurred in our preliminary consecutive experience, with specific focus on orbital outcome. METHODS: A retrospective and consecutive cohort of patients treated via a superior eyelid endoscopic transorbital approach at the Division of Neurosurgery of the Hospital Clinic in Barcelona was analyzed. Patients features were described in detail. Complications were divided into 2 groups to analyze separately the approach-related complications, and those resulting from tumor removal. The ocular complications were subdivided into early ocular status (<3 weeks), late ocular status (3-8 weeks), and persistent ocular complications. The "Park questionnaire" was used to determine patient's satisfaction related to the transorbital approach. RESULTS: A total of 20 patients (5 spheno-orbital meningiomas, 1 intradiploic Meningioma, 2 intraconal lesions, 1 temporal pole lesion, 2 trigeminal schwannoma, 3 cavernous sinus lesions, and 6 petroclival lesions) were included in the period 2017-2022. Regarding early ocular status, upper eyelid edema was detected in all cases (100%) associated with diplopia in the lateral gaze in 30% of cases, and periorbital edema in 15% of cases. These aspects tend to resolve at late ocular follow-up (3-8 weeks) in most cases. Regarding persistent ocular complications, in one case of intraconal lesion, a limitation of eye abduction was detected (5%). In another patient with intraconal lesion, an ocular neuropathic pain was reported (5%). In 2 cases of petroclival menigioma, who were also treated with a ventriculo-peritoneal shunt, slight enophthalmus was observed as a persistent complication (10%). According to the Park questionnaire, no cosmetic complaints, no head pain, no palpable cranial irregularities, and no limited mouth opening were reported, and an average of 89% of general satisfaction was encountered. CONCLUSIONS: The superior eyelid endoscopic transorbital approach is a safe and satisfactory technique for a diversity of skull base tumors. At late follow-up, upper eyelid edema, diplopia, and periorbital edema tend to resolve. Persistent ocular complications are more frequent after treating intraconal lesions. Enophthalmus may occur in patients with associated ventriculo-peritoneal shunt. According to patient's satisfaction, fairly acceptable results are attained.
