Many patients undergoing medial patellofemoral ligament (MPFL) reconstruction for patellofemoral instability have chondral or osteochondral injuries requiring treatment.

In patients undergoing MPFL reconstruction for patellofemoral instability, those with ligamentous laxity (LAX) would be less likely to have chondral or osteochondral defects requiring surgical intervention compared with those with no laxity (NLX).

Cohort study; Level of evidence, 2.

Included were 171 patients with patellofemoral instability (32 men, 139 women; mean age, 22 years [range, 11-57 years]) who underwent MPFL reconstruction between 2005 and 2015. Patients with a Beighton-Horan score ≥5 were considered LAX (n = 96), while patients with scores <5 were considered NLX (n = 75). Preoperative magnetic resonance images were evaluated to determine the presence, size, and location of chondral or osteochondral injury as well as the grade according to the Outerbridge classification. Documented anatomic measurements included tibial tc parameters (TT-TG distance and CDI), and trochlear morphology, patients with LAX were 75% less likely to have had a grade 3 or 4 patellar cartilage injury compared with patients with NLX (

= .006).

For patients who sustained patellar or femoral chondral or osteochondral injuries, compared with their counterparts with NLX, patients with LAX were less likely to have severe (grade 3 or 4) injuries requiring surgical intervention.

The patient was diagnosed in early adolescence with an atypical meningioma believed to be radiotherapy induced following treatment of a benign pilocytic astrocytoma in the hypothalamus region at 6 years of age. Even though the patient underwent several surgical and radiotherapy treatments, the intracranial meningioma kept growing and was locally invasive. The patient received experimental treatment with bevacizumab, a vascular endothelial growth factor A (VEGF-A)-inhibitor, for 4 years from age 26. Treatment was withdrawn after proven tumor growth on routine control MRI. A DOTA-TOC PET-CT-scan was performed to evaluate the DOTA-TOC somatostatin receptor number for possible SSTR (somatostatin receptor targeted therapy). In the included scan plan multiple lung metastasis were detected and later verified. Genomic tumor sequencing was performed, but no targeted treatment options were found. Instead, the patient finally, as the last treatment option, underwent 4 series of SSTR-targeted therapy (Lutetium DOTA-TOC). Unfortunately, the intracranial tumor component significantly progressed during the final stages of the treatment and the patient died less than a year after treatment was withdrawn at age 32. This case story illustrates the shortcomings of atypical/anaplastic meningioma treatment strategies at present and highlights the possibility of extracranial metastasis.Lumbar spinal stenosis is one of the most commonly diagnosed pathological conditions of the spine. Patients with lumbar spinal stenosis can be symptomatic or asymptomatic. Regardless of the clinical presentation, a combination of radiological imaging modalities including magnetic resonance imaging, CT, and dynamic X-rays can be used to evaluate the severity. An often underrecognized aspect of severe lumbar spinal stenosis is its effect on nerve roots. We propose coining the term "GatorSign" to describe nerve root edema above the area of severe central canal stenosis. This radiological finding can help identify patients with severe central canal stenosis in patients who would likely be neurologically symptomatic, requiring an invasive intervention such as epidural injections or surgical decompression for relief as conservative treatments such as physical therapy and/or medications are less likely to be effective.

The ideal approach to managing parastomal and small bowel ectopic varices (EVs) is yet to be established.

To evaluate outcomes following percutaneous antegrade transhepatic venous obliteration (PATVO) in patients presenting with bleeding from parastomal or small bowel EVs.

A case series of 12 patients presenting with active or recurrent bleeding from parastomal or small bowel EVs who underwent 17 PATVO interventions at our tertiary care institution was performed. Data extraction from electronic medical records included baseline characteristics and procedural details. Endpoints included technical success, early clinical success, and re-bleeding.

Technical success was 100% (

= 17), and early clinical success was 82.3% (

= 14). No patient experienced any intra- or post-operative complications. Rebleed rates after initial PATVO in patients who achieved early clinical success was as follows 3-month, 0% (

= 0); 6-month, 20% (

= 2); 12-month, 20% (

= 2). Rebleed rates after all PATVO procedures (including patients undergoing repeat procedures) that achieved early clinical success were as follows 3-month, 0% (

= 0); 6-month, 14% (

= 2; 12-month, 14% (

= 2). All patients with re-bleeding required reintervention with either PATVO, transjugular intrahepatic portosystemic shunt (TIPS) or both.

PATVO can be safely performed to treat bleeding from parastomal and small bowel EVs. In patients who present with recurrent bleeding despite PATVO, TIPS with/without embolization of bleeding varices remains a valid option as described by the literature.

Aqueous extracts from M. alternifolia were prepared by adding 2 grams of S. costus and M. alternifolia, respectively to 100 ml distilled water. Bacterial strains of P. gingivalis, E. faecalis and S. mutans were treated into 3 groups. In groups 1 and 2, bacterial strains were treated with aqueous extracts of S. costus and M. alternifolia, respectively. In the control-group, bacterial strains were exposed to distilled water. Antibacterial activity of the samples and nanoparticles was determined. The minimum-inhibitory-concentration (MIC) values were determined using the microdilution method. P less then 0.01 was considered statistically significant. The MIC for all bacterial strains treated with S. costus was significantly higher than that of M. selleck kinase inhibitor alternifolia (P less then 0.001). There was no significant difference in MIC for strains of P. gingivalis, E. faecalis and S. mutans treated with S. costus. For bacterial strains treated with M. alternifolia, the MIC was significantly higher for P. gingivalis compared with E. faecalis and S. mutans strains (P less then 0.01). There was no difference in MIC for E. faecalis and S. mutans strains treated with M. alternifolia. The in-vitro antibacterial efficacy of M. alternifolia is higher than S. costus against P. gingivalis, E. faecalis and S. mutans.

Randomized studies of neoadjuvant (NA) trastuzumab and pertuzumab combined with chemotherapy for HER2-positive breast cancers (BC) have reported pathological complete response (pCR) rates of 39 to 61%. This study aimed to determine the real-world efficacy and toxicity of NA trastuzumab and pertuzumab combined with chemotherapy in a UK tertiary referral cancer centre.

HER2-positive early BC patients given neoadjuvant chemotherapy with trastuzumab and pertuzumab between October 2016 and February 2018 at our tertiary referral cancer centre were identified via pharmacy records. Clinico-pathological information, treatment regimens, treatment-emergent toxicities, operative details, and pathological responses and outcomes were recorded.

78 female patients were identified; 2 had bilateral diseases and 48 of 78 (62%) were node positive at presentation. 55 of 80 (71%) tumours were ER-positive. PCR occurred in 37 of 78 (46.3%; 95% CI 35.3-57.2%) patients. 14 of 23 (60.8%) patients with ER-negative tumours achievedand consideration of strategies to increase the pCR rate.

Hereditary transthyretin amyloid cardiomyopathy (ATTR-CM) is a genotypically heterogeneous disorder with a poor prognosis. There is limited literature describing the variants responsible for ATTRv in areas outside the United State, the United Kingdom and Europe. This study was performed to describe the clinical characteristics and genotypic profiles of this disease in South China.

This was a single-center retrospective study that evaluated 29 patients with a confirmed diagnosis of hereditary transthyretin amyloid cardiomyopathy enrolled from January 2016 to November 2021.

93.1% patients were male and the median age of symptom onset was 53 (46, 62.5) years old. The initial manifestations of ATTR-CM were cardiovascular symptoms (55.2%), neuropathy (41.4%) and vitreous opacity (3.4%). Phenotypes at diagnosis were mixed (82.8%), predominant cardiac (6.9%), neurological (6.9%) and ophthalmic (3.4%). Poor R-wave progression (41%), pseudo-infarct (31%) and low-voltage (31%) patterns were common findings on eletion.

ATTR amyloidosis genotypes and phenotypes are highly heterogeneous. Advanced heart failure predicts a poor prognosis. Understanding the different clinical profiles of ATTR cardiac amyloidosis with different genotype is important to its early recognition.Coronary artery disease is among the primary causes of death worldwide. While synthetic grafts allow replacement of diseased tissue, mismatched mechanical properties between graft and native tissue remains a major cause of graft failure. Multi-layered grafts could overcome these mechanical incompatibilities by mimicking the structural heterogeneity of the artery wall. However, the layer-specific biomechanics of synthetic grafts under physiological conditions and their impact on endothelial function is often overlooked and/or poorly understood. In this study, the transmural biomechanics of four synthetic graft designs were simulated under physiological pressure, relative to the coronary artery wall, using finite element analysis. Using poly(vinyl alcohol) (PVA)/gelatin cryogel as the representative biomaterial, the following conclusions are drawn (I) the maximum circumferential stress occurs at the luminal surface of both the grafts and the artery; (II) circumferential stress varies discontinuously across the media and adventitia, and is influenced by the stiffness of the adventitia; (III) unlike native tissue, PVA/gelatin does not exhibit strain stiffening below diastolic pressure; and (IV) for both PVA/gelatin and native tissue, the magnitude of stress and strain distribution is heavily dependent on the constitutive models used to model material hyperelasticity. While these results build on the current literature surrounding PVA-based arterial grafts, the proposed method has exciting potential toward the wider design of multi-layer scaffolds. Such finite element analyses could help guide the future validation of multi-layered grafts for the treatment of coronary artery disease.
