Objectives The prion protein (PrP) plays a major role in central nervous excitability, cellular adhesion, and neurite outgrowth. We hypothesized that PrP variants may act as a modulator of chronic tinnitus, a condition frequently associated with states of overexcitability in the auditory pathway. Methods 139 Caucasian patients who presented with tinnitus lasting more than 6 months were recruited from a tinnitus clinic, underwent detailed neuro-otological examinations and donated venous blood for the extraction of genomic DNA from lymphocytes. Subjects with a history of vestibular schwannoma, Meniere's disease, or pathological middle ear conditions were excluded. Tinnitus severity was graded using the Tinnitus Questionnaire (TQ). A polymorphism encoding residue 117 of PrP was genotyped by PCR-based RFLP. Results When carriers of the minor PrP allele were compared to the remaining subjects, we noted only a moderate difference in mean TQ scores (33.4 ± 4.9 vs. 37.4 ± 1.5, p > 0.05). Conclusions The present results thus do not support a significant effect of PrP variant rs8124214 on subjective ratings of tinnitus. However, functional PrP variants may act on additional outcome parameters, e.g., on the response to treatment. Future studies will need to address the interplay of these variants, and their effects on specific subgroups.

SummaryPAI-2 is a fibrinolytic inhibitor produced predominantly by monocytes. Most PAI-2 is intracellular making study in clinical conditions difficult. Abnormalities in production may be associated with inflammation and fibrinolysis at sites of tissue damage such as the atherosclerotic plaque.PAI-2 gene variants have been described: variant A consists of Asn120, Asn404 and Ser413 and variant B consists of Asp120, Lys404 and Cys413. We designed a PCR-RFLP assay using primers spanning the region containing Asn/Lys404 and Ser/Cys413. Variant B contains an Mwol restriction site. We analysed 302 Pima Indians and 286 healthy Caucasian volunteers. To investigate relationships between genotype and vascular disease we analysed 333 Caucasian patients undergoing coronary angiography.Gene variant B was more common in the Pimas than in Caucasians (p <0.0001). There was no significant difference in genotype distribution between the volunteers and patients. In the patients there was no association between genotype and either a history of MI or extent of coronary atheroma.

Interest in psychiatric neurosurgery has waxed and waned since the 1930s. This chapter reviews the history of these methods, with a focus on OCD. This review of lesion procedures and deep brain stimulation includes neuropsychological and neuroimaging research in the context of putative neurocircuitry underlying symptoms and response to treatment. The chapter highlights how an abundance of caution is needed, as well as key issues in long-term management of patients so treated.

ObjectivesHIV-positive men who have sex with men (MSM) may be at a higher risk of repeat syphilis, have different clinical manifestations and have a different serological response to treatment compared with HIV-negative MSM. The objective of this study was to assess whether HIV-negative and HIV-positive MSM with infectious syphilis (primary, secondary or early latent) differed in history of previous syphilis episodes, disease stage and non-treponemal titre of initial and repeat episodes, and the titre response 6 and 12 months after treatment. Furthermore, determinants associated with an inadequate titre response after treatment were explored.MethodsThis retrospective analysis used data of five longitudinal studies (four cohorts; one randomised controlled trial) conducted at the STI clinic in Amsterdam, the Netherlands. Participants were tested for syphilis and completed questionnaires on sexual risk behaviour every 3–6 months. We included data of participants with ≥1 syphilis diagnosis in 2014–2019. Pearson’s χ² test was used to compare HIV-negative and HIV-positive MSM in occurrence of previous syphilis episodes, disease stage of initial and repeat syphilis episode and non-treponemal titre treatment responses.ResultsWe included 355 participants with total 459 syphilis episodes. HIV-positive MSM were more likely to have a history of previous syphilis episodes compared with HIV-negative MSM (68/90 (75.6%) vs 96/265 (36.2%); p<0.001). Moreover, HIV-positive MSM with repeat syphilis were less often diagnosed with primary syphilis (7/73 (9.6%) vs 36/126 (28.6%)) and more often diagnosed with secondary syphilis (16/73 (21.9%) vs 17/126 (13.5%)) and early latent syphilis (50/73 (68.5%) vs 73/126 (57.9%)) (p=0.005). While not significantly different at 12 months, HIV-negative MSM were more likely to have an adequate titre response after 6 months compared with HIV-positive MSM (138/143 (96.5%) vs 66/74 (89.2%); p=0.032).ConclusionsIn repeat syphilis, HIV infection is associated with advanced syphilis stages and with higher non-treponemal titres. HIV infection affects the serological outcome after treatment, as an adequate titre response was observed earlier in HIV-negative MSM.

Actinomyces meyeriis an uncommon cause of human actinomycosis. Here, we report a rare case of empyema caused byA. meyeri. A 49-year-old male presented with a history of 10 days of dyspnea and chest pain. A large amount of loculated pleural effusion was present on the right side and multiple lung nodules were documented on radiological studies. A chest tube was inserted and purulent pleural fluid was drained.A. meyeriwas isolated in anaerobic cultures of the pleural fluid. The infection was alleviated in response to treatment with intravenous penicillin G (20 million IU daily) and oral amoxicillin (500 mg every 8 hours) for 4 months, demonstrating that short-term antibiotic treatment was effective.

Phlegmonous gastritis was diagnosed in 2 yearling fillies that were presented with a 1-wk history of fever, lethargy, and hypoproteinemia, associated with a previous diagnosis of equine proliferative enteropathy based on clinical signs and PCR assay detection of Lawsonia intracellularis in fecal samples. Abdominal ultrasound revealed enlargement of the stomach and expansion of its submucosal layer with hypoechoic fluid, as well as thickened hypomotile small intestinal segments. Given the poor prognosis and poor response to treatment, both horses were euthanized, one on the day of presentation and the other after 3 wk of intensive medical management including a combination of antimicrobials, analgesics, and intravenous colloids. At autopsy, acute mural gastritis characterized by severe submucosal edema with suppurative inflammation (i.e., phlegmonous gastritis) and necroulcerative enteritis compatible with the necrotizing form of equine proliferative enteropathy were identified in both horses. The gastric inflammation was associated with thrombosis and mixed bacterial populations, including Clostridium perfringens, that were confined to the submucosa without evidence of mucosal involvement; toxin genes compatible with C. perfringens type C were identified in one case. Human phlegmonous gastritis is an uncommon, often-fatal pyogenic infection that is often associated with mucosal injury, bacteremia, or immunocompromise. Our finding of this unusual gastric lesion in 2 horses with similar signalment, clinical disease, and spectrum of postmortem lesions suggests a similar etiopathogenesis that possibly involves local, regional, or distant hematogenous origin, and should be considered a potential complication of gastrointestinal mucosal compromise in horses.

Introduction: Optic neuritis is one of the common causes of sudden visual impairment. Early diagnosis and treatment with intravenous steroids can hasten visual recovery. Objective: To analyze the demographic pattern, clinical profile, and response to treatment with pulse methylprednisolone in patients presenting with optic neuritis. Methods: A hospital based retrospective analysis of records of patients with optic neuritis presenting at BPKIHS between April 2010 to February 2012 was carried out. Demographic pattern, clinical profile and visual outcome at the time of presentation and discharge were recorded. Results: Thirty-five patients (44 eyes) presented with optic neuritis. A total of 33 eyes (75%) had papillitis and 11 eyes (25%) had retrobulbar optic neuritis. Male to female ratio was 2.18:1. The mean age at presentation was 31.20 ± 17.07 years. Diminution of vision was the commonest mode of presentation. Bilateral involvement was seen in 9 patients (25.71%). The 38 eyes (86.36%) had abnormal pupillary reaction. Eight patients (22.85%) had preceeding history of trauma, 1 (2.85%) had ethmoidal sinusitis and 1 (2.85%) otitis media. At the time of discharge 32 eyes (72.7%) showed recovery in visual acuity after pulse I.V. methylprednisolone therapy. Duration at presentation, visual acuity at presentation and diagnosis did not affect the final visual outcome (p=0.486, p=0.162 and p=0.122 respectively). Conclusion: Majority of patients presented with papillitis of idiopathic origin. Most of the cases were unilateral. Most patients with visual acuity of at least perception of light or better at the time of presentation improved after pulse I.V. methylprednisolone therapy.

AbstractPulmonary arterial hypertension (PAH) is a vascular disorder associated with significant morbidity and mortality. The pathophysiology of PAH remains controversial, but the only currently available therapies for PAH are pharmacological pulmonary artery vasodilation, decreasing right ventricular (RV) afterload, and relieving symptoms. By now, there is no therapy being able to minimize vascular remodeling processes and thus to reverse or delay the natural history of the disease. It has been generally thought that reduction of RV preload was detrimental, which deteriorated the systemic hemodynamics. In the present study, however, we repetitively and briefly occluded (RBO) both superior vena cava and inferior vena cava by ligation (occlusion for less than 5 seconds then re-open for 30 seconds and repeated 5 cycles as one sequence, 1 sequence every 6 hours) to intermittently restrict RV preload, for continuous 24 hours, total 5 sequences, in the Sugen 5416 (VEGF receptor blocker) and hypoxia induced PAH rat models and we found this strategy was beneficial for lowering pulmonary vascular resistance (PVR).

The aim of this retrospective study was to analyze the pharmacotherapy regimens of the decompensated form of type 2 diabetes mellitus (DM2) and to evaluate its effectiveness, its compliance with clinical recommendations.Materials and methods: A retrospective analysis of 54 medical cards of patients with decompensated DM2 was conducted. The 1st group (n=24; 44%) included the patients who had a decrease in glycated hemoglobin (HbA1c) by 50% or more in 3 months after hypoglycemic therapy; and the 2nd group (n=30; 56%) – the patients whose HbA1c level decreased by less than 50%.Results. A HbA1c level was 10.4% in the 1st group and 13.2% in the 2nd group (р<0.001). However, the target levels of venous blood plasma glucose and HbA1c were not achieved in any of the patient groups. The total number of the drugs prescribed to the patients ranged from 4 (in 25% (n=6) and 10% (n=3) cases in the 1st and the 2nd groups, respectively) to 8 (in 12.5% (n=3) and 20% (n=6) cases in the 1st and the 2nd, groups, respectively). However, in a number of cases some violations of clinical recommendations were recorded: the prescription to the obese patients of insulin drugs, the administration of sulfonylureas derivatives to patients with a history of cardiovascular diseases of the atherosclerotic origin, but modern hypoglycemic drugs with proven benefits in reducing cardiovascular risks were rarely prescribed.Conclusion. The tactics of pharmacotherapy in the patients with a decompensated form of DM2 does not fully comply with the approved clinical guidelines, which requires the effectiveness of treatment optimization of this medically and socially significant pathology.
