Problems, obstacles and complications of femoral lengthening with the use of the Italian modification of the Ilizarov device]

The results of femoral lengthening using the Italian modification of the Ilizarov are presented. Mean age of the patients was 14 years (ranging from 7 to 29). The most frequent etiology of limb shortening was femoral hypoplasia (7 patients) and sequelae of septic arthritis of the hip and/or the knee (6 patients). Indications for surgical treatment were limb shortening from 3 to 12 cm (mean 6.5 cm), along with axial deviation ranging from 10 degrees to 40 degrees in 6 patients. Mean follow-up time was 15 months (ranging from 6 to 35 months). The Ilizarov apparatus was based on two distal rings, stabilized by "K" wires, and proximally by a ring connected with an Italian femoral arch, stabilized by a Schanz screw. Planned lengthening (ranging from 3.5 cm to 12 cm) was achieved in all treated patients. The healing index ranged from 0.8 to 2.1 month/cm (mean 1.4). Problems, obstacles and complications were analyzed according to the Paley classification. In all 16 patients without primary knee stabilization, limited knee flexion ranging from 5 degrees to 90 degrees (mean 40 degrees) was noted during the distraction phase, which didn't improve significantly during the consolidation phase. Knee flexion improved to a mean 90 degrees after a 6 month follow-up. Bone regenerate defects (cysts, narrowing) were noted in 4 patients. Secondary knee stabilization was performed in 2 cases. In the first case because of knee pain and a severe limitation of knee motion. In the second, during a revision procedure because of distal femur angulation. Premature consolidation was noted in one patient and was treated by osteotomy. In one case axial deviation during the consolidation phase required osteotomy. In another case a fracture of the femur was treated by a plaster cast. In one case 1.5 years after the lengthening procedure subluxation of the hip was noted. Permanent knee flexion limitation to less than 90 degrees was noted in 6 patients. Femoral lengthening with the use of the Italian modification of the Ilizarov device give a high incidence of knee range of motion limitation, which can be decreased by preserving more than 30 degrees knee flexion during the distraction phase.     

Service‐user experiences of an integrated psychological intervention for depression or anxiety and tobacco smoking in improving access to psychological therapies services: A qualitative investigation into mechanisms of change in quitting smoking

IntroductionHigh smoking prevalence leads to increased morbidity and mortality in individuals with depression/anxiety. Integrated interventions targeting both smoking and mood have been found to be more effective than those targeting smoking alone, but the mechanisms of change of these interventions have not been investigated. This qualitative study aimed to understand participants'' experiences of the mechanisms underlying change in smoking behaviour following an integrated cognitive behavioural technique‐based intervention for smoking cessation and depression/anxiety.MethodsThis study was embedded within an ongoing randomized‐controlled acceptability and feasibility trial (http://www.isrctn.com/ISRCTN99531779). Semistructured interviews were conducted with 15 IAPT service users. Data were analysed using thematic analysis. During the interviews, participants were asked open‐ended questions about their quitting experience and perception of how the intervention aided their behaviour change.ResultsFive themes were identified. Acquiring an increased awareness of smoking patterns: participants described an increased understanding of how smoking was contributing towards their mental health difficulty. Developing individualized strategies: participants described acquiring ‘a couple of tricks up your sleeve’ that were helpful in making smoking cessation feel more ‘manageable’. Practitioner style as ‘supportive but not lecture‐y’: participants expressed how important the therapeutic alliance was in helping change their smoking behaviour. Importance of regular sessions: participants expressed the importance of ‘having someone that''s checking in on you’. Having the opportunity to access the intervention at ‘the right time’: participants described the intervention as the ‘push’ that they ‘needed’.ConclusionsParticipants identified key factors towards smoking behaviour change. Perceived increased awareness of how smoking negatively impacted participants'' mental health, and the opportunity to be offered smoking cessation treatment in a ‘non‐judgemental’, ‘supportive’ environment, with regular sessions and individualized strategies contributed to successful smoking cessation outcomes. If similar results are found in more diverse samples, these aspects should be embedded within integrated interventions for smoking cessation and depression/anxiety.Patient or Public ContributionPersons with lived experience of depression, anxiety and tobacco addiction contributed towards the design of the interview schedule, participant information sheets and the debriefing process. This was to ensure that interview questions were relevant, nonjudgemental and acceptable for those who did not manage to quit smoking.     

Chronic stress and obesity: a new view of "comfort food"

The effects of adrenal corticosteroids on subsequent adrenocorticotropin secretion are complex. Acutely (within hours), glucocorticoids (GCs) directly inhibit further activity in the hypothalamo-pituitary-adrenal axis, but the chronic actions (across days) of these steroids on brain are directly excitatory. Chronically high concentrations of GCs act in three ways that are functionally congruent. (i) GCs increase the expression of corticotropin-releasing factor (CRF) mRNA in the central nucleus of the amygdala, a critical node in the emotional brain. CRF enables recruitment of a chronic stress-response network. (ii) GCs increase the salience of pleasurable or compulsive activities (ingesting sucrose, fat, and drugs, or wheel-running). This motivates ingestion of "comfort food." (iii) GCs act systemically to increase abdominal fat depots. This allows an increased signal of abdominal energy stores to inhibit catecholamines in the brainstem and CRF expression in hypothalamic neurons regulating adrenocorticotropin. Chronic stress, together with high GC concentrations, usually decreases body weight gain in rats; by contrast, in stressed or depressed humans chronic stress induces either increased comfort food intake and body weight gain or decreased intake and body weight loss. Comfort food ingestion that produces abdominal obesity, decreases CRF mRNA in the hypothalamus of rats. Depressed people who overeat have decreased cerebrospinal CRF, catecholamine concentrations, and hypothalamo-pituitary-adrenal activity. We propose that people eat comfort food in an attempt to reduce the activity in the chronic stress-response network with its attendant anxiety. These mechanisms, determined in rats, may explain some of the epidemic of obesity occurring in our society.     

Percutaneous interventions in patients with cocaine-associated myocardial infarction: a case series and review.

Cocaine-associated myocardial infarction (CAMI) is a well-reported entity. Most previous reports on CAMI have been limited to conservative care utilizing benzodiazepines, aspirin, nitroglycerin, calcium channel blockers, and thrombolytics. Current guidelines on CAMI advocate immediate use of angiography and angioplasty if available rather than routine administration of thrombolytics. However, based on literature search from 1966 to 2001 (using keywords "cocaine," "myocardial infarction," and "angioplasty"), there have been only two case reports of percutaneous coronary intervention (PCI) in patients with cocaine-associated myocardial infarction. Both were notable for complications either during or immediately after the procedure. We report a series of 10 patients with cocaine-associated myocardial infarction who were treated with percutaneous interventions, which included angioplasty, stenting, and AngioJet mechanical extraction of thrombus. Despite the different arteriopathic process involved, our findings suggest that PCI can be performed safely and with a high degree of procedural success in patients with CAMI.     

Indomethacin may reduce the incidence and severity of acute pancreatitis after ERCP

OBJECTIVES: Acute pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Many medications have been used to prevent this complication. We aimed to evaluate the efficacy of rectally administered indomethacin for the prevention of post-ERCP pancreatitis. METHODS: During 18 months, all eligible patients who underwent ERCP were enrolled in this study. In a double-blind randomized trial, patients received a suppository containing indomethacin, 100 mg, or an inert placebo immediately before ERCP. Serum amylase levels and clinically pertinent evaluations were measured in all patients after ERCP. RESULTS: A total of 490 patients entered the trial, of which half received indomethacin. Twenty-two patients developed pancreatitis; seven cases in the indomethacin group and 15 in the placebo group (P=0.06). Pancreatic duct injection (OR=3.0, 95% CI: 1.3-7.4), pancreatic duct cannulation more than once (OR=4.2, 95% CI: 1.7-10.0), and age less than 60 yr (OR=2.7, 95% CI: 1.0-7.1) were shown to be significant risk factors for developing post-ERCP pancreatitis. In patients who underwent pancreatography with or without cholangiography, the risk of pancreatitis was significantly lower in the indomethacin group compared with the control group (P=0.01, RRR=88%, ARR=0.16, NNT=6). Moderate to severe pancreatitis was significantly higher in the placebo group (P= 0.03). CONCLUSIONS: This trial shows that rectal indomethacin given immediately before ERCP can reduce the incidence and severity of post-ERCP pancreatitis.     

Osteomyelitis due to multiple carbapenemase-producing Gram-negative bacteria: The first case report of a GES-13-producing Pseudomonas aeruginosa isolate in Canada

A case of osteomyelitis in an infant following a burn injury sustained in Pakistan caused by a GES-13-producing Pseudomonas aeruginosa (the first reported in Canada) and an OXA-48 producing Klebsiella pneumoniae is described. The present case serves to highlight the importance of international travel as a risk factor for infection with carbapenemase-producing bacteria and the challenges in the laboratory detection of these organisms.     

Utility of common bile duct measurement in ED point of care ultrasound: A prospective study

Background

Measurement of the common bile duct (CBD) is considered a fundamental component of biliary point-of-care ultrasound (POCUS), but can be technically challenging.

Systemic Inflammatory Response Syndrome is Associated with Hematoma Expansion in Intracerebral Hemorrhage

ObjectivesSystemic inflammatory response syndrome (SIRS) and hematoma expansion are independently associated with worse outcomes after intracerebral hemorrhage (ICH), but the relationship between SIRS and hematoma expansion remains unclear.Materials and methodsWe performed a retrospective review of patients admitted to our hospital from 2013 to 2020 with primary spontaneous ICH with at least two head CTs within the first 24 hours. The relationship between SIRS and hematoma expansion, defined as ≥6 mL or ≥33% growth between the first and second scan, was assessed using univariable and multivariable regression analysis. We assessed the relationship of hematoma expansion and SIRS on discharge mRS using mediation analysis.ResultsOf 149 patients with ICH, 83 (56%; mean age 67±16; 41% female) met inclusion criteria. Of those, 44 (53%) had SIRS. Admission systolic blood pressure (SBP), temperature, antiplatelet use, platelet count, initial hematoma volume and rates of infection did not differ between groups (all p>0.05). Hematoma expansion occurred in 15/83 (18%) patients, 12 (80%) of whom also had SIRS. SIRS was significantly associated with hematoma expansion (OR 4.5, 95% CI 1.16 - 17.39, p= 0.02) on univariable analysis. The association remained statistically significant after adjusting for admission SBP and initial hematoma volume (OR 5.72, 95% CI 1.40 – 23.41, p= 0.02). There was a significant indirect effect of SIRS on discharge mRS through hematoma expansion. A significantly greater percentage of patients with SIRS had mRS 4-6 at discharge (59 vs 33%, p=0.02).ConclusionSIRS is associated with hematoma expansion of ICH within the first 24 hours, and hematoma expansion mediates the effect of SIRS on poor outcome.
