Treatment of Heavily Calcified Coronary Lesions In Switzerland and other industrialized nations, coronary heart disease (CHD) is the most common cause of death in adulthood. CHD is a chronic disease in which stenoses of the epicardial coronary arteries usually cause a deficit in blood supply to the heart muscle tissue, which can lead to chest pain, myocardial infarction, heart failure or cardiac arrhythmia and ultimately to significant morbidity and mortality. Since the first percutaneous coronary intervention (PCI) on 16th September 1977 at the University Hospital of Zurich by Andreas Grüntzig, the field of interventional cardiology has seen remarkable progress in the treatment of coronary artery disease, especially with the development and evolution of coronary stents. Nonetheless, calcified coronary stenoses pose a challenge in everyday interventional practice because they prevent stent implantation or correct expansion or are associated with a higher rate of complications. Unfortunately, to date, there are no established interventions to prevent calcification of the coronary arteries. However, there are some therapeutic approaches that allow PCI in calcified vessels, and these are the focus of this work.

A retrospective analysis of the horizontal video head impulse test (vHIT) results and caloric testing results was undertaken on 644 patients who attended a neuro-otology outpatient facility. Presenting symptoms included spontaneous vertigo, positional vertigo, imbalance or chronic subjective dizziness. For 570 patients, the results of vHIT and caloric testing were concordant. Both tests were normal in 500 subjects with an average vHIT gain = 0.92 ± 0.09 (L); 0.98 ± 0.10 (R) and canal paresis (CP) = 7.88 ± 6.12; (range 0-28%). 54 had concordant asymmetries, average ipsilesional vHIT gain = 0.56 ± 0.15, average contralesional vHIT gain = 0.88 ± 0.12. CP = 68.02 ± 24.38 (range 31-100%). 16 subjects had bilateral vestibular hypofunction with average vHIT gains of 0.42 ± 0.20 (L); 0.41 ± 0.19 (R), peak slow phase velocity (SPV) on warm caloric testing = 2.68 ± 2.08, range 0-6°/s (L) and 3.75 ± 3.43 range, 0-10°/s (R). 36 patients showed a dissociation of results between the two tests. In these subjects, the vHIT gain was normal (0.93 ± 0.06 left and 0.98 ± 0.07 right) and the caloric test showed a CP > 30% (48 ± 13.8%). Their final diagnoses included clinically definite Meniere's disease (MD) (n = 27), vestibular schwannoma (VS) (n = 2) vestibular migraine (VM) (n = 1), vestibular neuritis (VN) (n = 5) and unknown (n = 1). No patient with abnormal HSCC gain on vHIT had a normal caloric result. The caloric test complements the vHIT in the assessment of vestibular disorders and is most useful in suspected endolymphatic hydrops. Asymmetric caloric function in the presence of normal horizontal head impulse tests is most commonly associated with Meniere's disease and may function as a diagnostic marker.

Neuropsychiatric manifestations like cognitive dysfunction, peripheral neuropathy, stroke headache, seizures in systemic lupus erythematosus (SLE) are quite common. However, psychosis as the sole presenting manifestation of SLE is rarely encountered clinically. If lupus is not kept as differential among patients with acute psychosis, delay in diagnosis and subsequent mismanagement are likely to happen. Here, we present a case of a young female presenting with acute psychosis as the predominant symptom and was further evaluated and diagnosed as a case of SLE. The patient was managed with immunosuppressive agents and carried an excellent outcome.

ST-elevation myocardial infarction (STEMI) requires timely coronary reperfusion but localizing ST-segment elevation (STE) can develop in clinical settings other than STEMI.

A 11-year-old boy presented to the gastroenterology clinic after a 5-month history of fatigue, pallor, intermittent abdominal pain, and iron-deficiency anemia. Although the initial upper endoscopy was visually normally, the histological assessment was suggestive of eosinophilic gastritis. After multiple scopes and failed therapies, histologic analysis revealed a focus of thickened subepithelial collagen deposition suggestive of collagenous gastritis. A retrospective review of gastric biopsies using Gomori trichrome stain revealed previously unappreciated collagen deposition. This case report illustrates the benefit of performing trichrome stain on gastric biopsies in the setting of persistent or isolated gastric eosinophilia or iron deficiency anemia.

Because the knee is the joint of the human body with the largest surface, it is no wonder that gonalgia is one of the most common complaints in the general population. Although the management of a painful traumatic knee is relatively well standardized, that of a non-traumatic knee pain is less codified. History and a rigorous systematic clinical examination play a key role in the management of nontraumatic gonalgia. The diagnostic approach is mainly guided by the inflammatory or mechanical nature of the pain and its topography. This article aims to clarify the diagnostic approach to gonalgia without notion of prior trauma.

Osteoarthritis (OA) is one of the most common degenerative diseases, ultimately leading to long-term joint pain and severe articular malformation. Controlling local chronic inflammation is a crucial strategy for delaying OA development. Linarin is a natural flavonoid glycoside that is widely available in Compositae, Chrysanthemum indicum and Dendrocalamus and processes protective effects in several animal models. The purpose of our work was to study the protective effect of Linarin for OA. Cellular experiments data showed that Linarin suppressed lipopolysaccharide (LPS)-caused the overproduction of nitric oxide (NO), prostaglandin E2 (PGE2), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α) in chondrocyte. In addition, LPS-stimulated expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide nitrate (iNOS) was decreased by Linarin pre-treatment. Together, Linarin prevented the catabiosis of extracellular matrix caused by LPS. For mechanism, Linarin inhibited the formation of Toll-like receptor 4 (TLR4) / myeloid differentiation protein-2 (MD-2) dipolymer complex and subsequently intervened NF-κB activation. Our mouse DMM model further clarified the protection of Linarin . In summary, our results suggested that Linarin may be a potential effective agent for OA.

The aim of this study is to compare the effects of two different uterine closure techniques, used during cesarean section (CS) operations on isthmocele formation.

Bupropion is taken as an antidepressant for treatment of major depressive disorders, treatment of sexual side effects of selective serotonin reuptake inhibitors, and as a smoking cessation aid, however, it may result in adverse effects such as nausea, dry mouth, headache, insomnia, dizziness, anxiety, tremor, and constipation. We investigate the case of a 34-year-old woman with bulimia nervosa where acute dystonia was induced by bupropion in 8 months. Following this diagnosis and after normal tests and MRI results, the patient was advised to discontinue bupropion intake. In the follow-up done 2 weeks later, 3 months later, and 6 months later, no signs of acute dystonia was observed. A physician who administers dopamine blocking agents must be aware of the prevalence of and the risk factors for acute dystonia and also the way of prevention and treatment.

Mesalazine is a well-established 1st line treatment for inflammatory bowel disease (IBD). Cardiotoxicity following 5-aminosalicyclic-acid therapy remains a rare yet serious complication and can often be challenging to distinguish from myocarditis presenting as an extra-intestinal manifestation of IBD.
