Congenital portosystemic shunts are a common cause of hepatic encephalopathy and are typically first identified when dogs are <2 years of age. This case series describes five dogs with congenital portosystemic shunts; the dogs were presented for severe encephalopathic signs during middle or old age. Three dogs had portoazygos shunts, and four dogs had multifocal and lateralizing neurological abnormalities, including severe gait abnormalities and vestibular signs. All five dogs responded to medical or surgical treatment, demonstrating that older animals can respond to treatment even after exhibiting severe neurological signs.

SummaryObjective: To describe the surgical treatment and outcome for juvenile dogs with cranial thoracic vertebral canal stenosis treated by unilateral hemilaminectomy.Study design: Case series.Animals: Three large-breed brachycephalic dogs of various breeds (Dogue de Bordeaux, Australian Bulldog, Boerboel) with neurological signs consistent with a myelopathy of the third thoracic (T) to third lumbar (L) spinal cord segment.Methods: Information on clinical presentation, diagnostic imaging, surgical procedures, postoperative complications, recovery and outcome is described.Results: Neurological signs were present and progressive for two to four weeks prior to surgery and ranged from mild ataxia to paralysis. Cranial thoracic vertebral canal stenosis was diagnosed with computed tomography imaging. Lateral and dorsolateral spinal cord compression was present at multiple sites between T2 and T6. Alternating left and right-sided compressions were common. Surgical treatment was by unilateral, continuous hemilaminectomy over three to six vertebral spaces. Postoperative morbidity was minimal and return of independent ambulation was rapid (median: 13.5 days, range: 2–29 days). Neurological status in one dog worsened four months after surgery due to reoccurrence of osseous compression; unilateral hemilaminectomy was repeated in this dog. Long-term follow-up ranged from six to 10 months; neurological signs had completely resolved in one dog and substantially improved in the other two dogs.Clinical significance: Unilateral hemilaminectomy was associated with rapid return of independent ambulation and substantial improvement in neurological scores.

Background: Traumatic internal degloving injury i.e. Morel-Lavallée lesion (MLL) develops as a result of blunt trauma with tangential shear forces. In the pediatric population, these have been described only as small case reports till date. Purpose: To describe the largest case series of lower extremity Morel-Lavallée lesion (MLL) in the pediatric population, to determine its etiology (especially its relationship to sports), treatment and outcomes. Methods: Retrospective study of patients <18 years presenting to a tertiary children’s hospital with MLL between 2013-2019. Demographics, clinical data, imaging features, treatment and outcomes data was collected. Descriptive statistical analysis was conducted. Results: 38 patients (21 males, 17 females) having MLL with mean age 14.6 years were classified into 2 groups- hip/thigh MLL (9 patients) and lower leg MLL (29) (Table 1.1). Most common cause of lower leg MLL was sports injury (79%). Most commonly implicated sports in MLL were football and baseball(24% each). Associated injuries were seen in 9 (23%) patients. Radiographs done in 58% of patients showed no bony abnormalities. Imaging modality of choice was MRI for lower leg MLLs (72%) and US for hip/thigh MLL (67%)(Fig.1.2). MLL size was larger for hip/thigh MLL (168 cm3) as compared to leg MLL (38.6 cm3). 25 (65.8%) of MLLs were treated with conservative management,12 (31.5%) with minimally invasive methods and 1(2.6%) needed surgical management. 2/9 (22.2%) of the associated injuries required operative management. 2/38 (5%) patients were given prophylactic antibiotics. 72.4% Lower leg MLLs were treated with conservative management while intervention was needed more in hip/thigh MLLs (55.6%). Patients returned to activities at 14.3 weeks for hip/thigh MLL;9.1 weeks for lower leg MLL. 24 patients with adequate documentation demonstrated lower extremity functional score (LEFS) and pain level of 74/80 (92.5%) and 0.7/10 respectively at mean 12.5 months follow-up. Leg cellulitis was seen as a complication in one patient. Conclusion: The largest case series on MLL exclusively in the pediatric population suggests that they are more common in knee/leg region region and usually caused by sports injuries which is notably different as compared to adult population. Most pediatric injuries are treated conservatively, especially sports related MLLs. Although return to activities takes longer for hip/thigh injuries, majority of patients regain satisfactory functionality post-injury. [Table: see text][Figure: see text]

Abstract Background During flight, atmospheric pressure drop, low humidity and restricted motion occur. The environmental change can evoke the stroke occurrence. However, description of in-flight stroke case series has been limited until now. We investigated the clinical and flight trip characteristics of in-flight stroke cases in Korea. Method Since the opening of Incheon international airport, which is used by about 50 million people a year, in 2001, our hospital branch has been located at the airport and all the emergency stroke patients have been referred to our hospital. We performed retrospective review of the prospectively collected stroke registry and the information about the flight from January 2001 to December 2018. Results During the study period, 31 in-flight stroke cases were identified among total 1,452 ischemic stroke patients (17 men, 62±15 years old). Twenty-six patients had cerebral infarction, and four patients had transient ischemic attack. On etiological classification of cerebral infarction, 19 large artery atherothrombosis (61.3%), 1 septic embolism, 3 cryptogenic stroke, 3 cardioembolism (9.7%) and 1 cerebral venous thrombosis were identified. Six patients had Patent Foramen Ovale. Twenty-two patients reported to experience symptom around landing. Fourteen patients had flight for six hours or longer. Compared to the patients with long flight time (≥6 hrs), those with short flight time had the higher incidence of stroke occurrence around landings (32 vs 68%) and low incidence of unclear stroke onset. Poor outcome, defined as mRS 4 or higher, was associated with old age, unclear stroke onset, and early neurologic deterioration. Conclusion In-flight stroke is uncommon, and can easily be neglected during flight, which result in poor outcome. The stroke risk seems to be relatively high around landing, especially in the travelers with short flight time. The possibility of paradoxical embolism related to motion restriction seems low for stroke occurrence. Old age and unclear stroke onset are associated with poor outcomes.

Oxalate Nephropathy

<b><i>Introduction:</i></b> Secondary oxalate nephropathy (OxN) is associated with a variety of causes and has not been well characterized in Chinese population. To investigate the etiology, clinicopathological features, and outcomes of secondary OxN, we report a case series from a single center in China. <b><i>Methods:</i></b> A retrospective analysis of 68 patients diagnosed with secondary OxN by renal biopsy from January 2013 to February 2019 in Jinling Hospital was performed. <b><i>Results:</i></b> Secondary OxN accounted for 0.23% of the renal biopsies and 2.31% of patients who received renal biopsies due to acute kidney injury (AKI). A total of 49 men and 19 women with an average age of 51.6 ± 11.8 years were enrolled. The most common cause was iatrogenic medication, followed by oxalate-rich diet and industry exposure. Stage 1, 2, and 3 AKI and AKI on chronic kidney disease (ACKD) were found in 4.4, 8.8, 69.1, and 17.6% of the patients, respectively. The peak serum creatinine during hospitalization was 8.62 ± 4.67 mg/dL. The median urinary oxalate excretion was 51.5 (23.2–147.1) mg/24 h. Kidney biopsy showed extensive calcium oxalate crystal deposits with acute tubulointerstitial nephritis. Thirty-four patients (50.0%) required renal replacement therapy. At the end of a follow-up that lasted 8.7 (0.1–72.1) months, 81.0% of patients achieved renal function recovery in 50 (14–432) days. Patients with renal function recovery had a lower rate of ACKD, a higher level of hemoglobin, a lower level of urine lysozyme, and a lower degree of interstitial fibrosis/tubular atrophy, interstitial inflammation, and global glomerulosclerosis than those in the nonrecovery group. <b><i>Conclusions:</i></b> In this case series of secondary OxN, the most common cause was iatrogenic medication, and it presented with AKI or ACKD. Half of the patients required renal replacement therapy, and in most of them, the renal function was reversible. Renal biopsy played an important role in diagnosis and prognosis evaluation.

Hepatic encephalopathy (HE) is a common neurological consequence in patients with cirrhosis and has a healthcare burden of USD 5370 to 50,120 per patient annually. HE significantly hampers the quality of life and is a major cause of morbidity and mortality. Patients with cirrhosis are at a high risk for protein-calorie malnutrition due to altered metabolism. Current evidence has changed the old belief of protein restriction in patients with cirrhosis and now 1.2 to 1.5 g/kg/day protein intake is recommended. Case series and studies with small numbers of participants showed that a vegetarian protein diet decreases the symptoms of HE when compared to a meat-based diet, but the evidence is limited and requires further larger randomized controlled trials. However, vegetable or milk-based protein diets are good substitutes for patients averse to meat intake. Branch chain amino acids (BCAA) (leucine, isoleucine and valine) have also been shown to be effective in alleviating symptoms of HE and are recommended as an alternative therapy in patients with cirrhosis for the treatment of HE. In this review, we provide an overview of current literature evaluating the role of protein intake in the management of HE in cirrhosis.

Passive Stress

Midcarpal instability is a collective term for a number of conditions where the instability of the wrist is predominantly between the proximal and distal carpal rows. It has been regarded as relatively rare and infrequently requires surgical treatment. Palmar midcarpal instability is the most commonly found type of midcarpal instability and can be responsible for causing a clunking and painful wrist. The diagnosis is made on clinical grounds using the midcarpal instability provocative tests. Standard imaging and arthroscopic inspection do not usually confirm a definite diagnosis, but are important in excluding other pathologies. The classification and staging has been described using the extent of palmar translocation of the distal carpal row, which is elicited on passive stress tests. As this is a functional instability, it may be that a functional staging description might be better, and a proposed scheme is described. Treatment options including partial wrist fusions, tenodesis stabilizations and arthroscopic capsular shrinkage have been described in small case series with limited follow-up. There are no comparative series or randomized studies because of the relative rarity of this condition.

AbstractAn increasing incidence of sacral insufficiency fractures in geriatric patients has been documented, representing a major challenge to our healthcare system. Determining the accurate diagnosis requires the use of sectional imaging, including computed tomography and magnetic resonance imaging. Initially, non-surgical treatment is indicated for the majority of patients. If non-surgical treatment fails, several minimally invasive therapeutic strategies can be used, which have shown promising results in small case series. These approaches are sacroplasty, percutaneous iliosacral screw fixation (S1 with or without S2), trans-sacral screw fixation or implantation of a trans-sacral bar, transiliac internal fixator stabilisation, and spinopelvic stabilisation. These surgical strategies and their indications are reported in detail. Generally, treatment-related decision making depends on the clinical presentation, fracture morphology, and attending surgeonʼs experience.

Question Survey

OBJECTIVE Indication for surgery in brainstem cavernous malformations (BSCMs) is based on many case series, few comparative studies, and no randomized controlled trials. The objective of this study was to seek consensus about surgical management aspects of BSCM. METHODS A total of 29 experts were invited to participate in a multistep Delphi consensus process on the surgical treatment of BSCM. RESULTS Twenty-two (76%) of 29 experts participated in the consensus. Qualitative analysis (content analysis) of an initial open-ended question survey resulted in 99 statements regarding surgical treatment of BSCM. By using a multistep survey with 100% participation in each round, consensus was reached on 52 (53%) of 99 statements. These were grouped into 4 categories: 1) definitions and reporting standards (7/14, 50%); 2) general and patient-related aspects (11/16, 69%); 3) anatomical-, timing of surgery–, and BSCM-related aspects (22/37, 59%); and 4) clinical situation–based decision-making (12/32, 38%). Among other things, a consensus was reached for surgical timing, handling of associated developmental venous anomalies, handling of postoperative BSCM remnants, assessment of specific anatomical BSCM localizations, and treatment decisions in typical clinical BSCM scenarios. CONCLUSIONS A summary of typical clinical scenarios and a catalog of various BSCM- and patient-related aspects that influence the surgical treatment decision have been defined, rated, and interpreted.
