Local approach to order continuity in Ces\`aro function spaces
The goal of this paper is to present a complete characterisation of points of
order continuity in abstract Ces\`aro function spaces for being a
symmetric function space. Under some additional assumptions mentioned result
takes the form . We also find simple equivalent condition for
this equality which in the case of comes to .
Furthermore, we prove that is order continuous if and only if is,
under assumption that the Ces\`aro operator is bounded on . This result is
applied to particular spaces, namely: Ces\`aro-Orlicz function spaces,
Ces\`aro-Lorentz function spaces and Ces\`aro-Marcinkiewicz function spaces to
get criteria for OC-points.Comment: 18 page
Treatment of the dens fractures in children
The anatomical and biomechanical features of the immature cervical spine make the upper segments at C1–3 especially susceptible to injury.
Material and method
From 2000 to 2016, 10 patients (3 boys, 7 girls) with C2 dens fractures were treated. The average age of each child was 11 years (3–17). According to the Anderson classification, there were 6 patients with a type III fracture and 4 with a type II. 4 patients were treated conservatively using the Minerva cervical brace for 75 days (66–125) and 6 patients by means of the Halo-Vest for 79 days (64–87) and followed by the Schantz collar for 17 days (2–35).
Results
The follow up lasted 78 months (12–180). The NDI (Neck Disability Index) score was calculated for each patient, except for section 8 (driving the car). The scores ranged from 1/45 (2.22%) to 20/45 (44.44%). The mean score for 9 out of the 10 patients (one patient died) was 4.77 (10.61%).
Conclusion
The C2 dens fracture is a rare injury in children. The classification system of dens fractures developed by Anderson is useful in choosing the mode of treatment of dens fractures
Health-related quality of life in ischaemic stroke survivors after carotid endarterectomy (CEA) and carotid artery stenting (CAS) : confounder-controlled analysis
Introduction: Atherosclerotic carotid artery stenosis (CS)-related strokes are a significant overall stroke burden contributor. Aim: To evaluate the effect of surgical (carotid endarterectomy – CEA) vs. percutaneous (neuroprotected carotid artery stenting – CAS) carotid revascularization on health-related quality of life (HRQoL) in stroke survivors: analysis controlled for major HRQoL determinants beyond strokes. Material and methods: Our database of 856 carotid revascularization procedures (48.7% symptomatic CS) performed over 3 years showed 42 pairs (CEA-CAS) of right hemispheric stroke patients matched for age, sex, marital and educational status, hypertension, heart failure and diabetes, who underwent uneventful carotid revascularization, experienced no major adverse clinical events, and completed the Short Form Outcome Study (SF-36) questionnaire within 7 days before, 14 days after, 6 months after, and 12 months after carotid revascularization. Results: Baseline HRQoL was low and similar in both groups (30.8 ±4.6% vs. 29.1 ±3.9%, p = 0.68; data given for CEA vs. CAS). National Institute of Health Stroke Scale chronic severity was 5.4 ±2.8 vs. 5.9 ±3.1 (p = 0.44). Revascularization was associated with a major HRQoL improvement, that was significantly greater in CAS (60.4 ±9.2% vs. 71.5 ±6.2%, p < 0.001). At 6 months the CEA-CAS difference was narrower (70.7 ±9.7% vs. 74.6 ±5.9%, p = 0.026), becoming statistically insignificant at 12 months (72.6 ±6.7% vs. 75.1 ±5.1%, p = 0.062). The early CEA-CAS difference was driven by less bodily pain and better physical functioning/role-physical plus better role-emotional and higher general well-being scores in CAS (p < 0.05). Conclusions: Carotid revascularization has a major positive impact on stroke survivor patient-reported HRQoL. The improvement is initially greater in CAS, with the remaining difference small at 12 months and statistically insignificant
Orbital trauma with a large wooden foreign body: a case report
Introduction: Injuries caused by a foreign bodies in the craniofacial region constitute a significant percentage of accidents during the work. The most serious problem is to determine the exact location and extent of damage caused by a foreign body. The aim of work is to present a scheme of conduct in case of a foreign body inside the eye socket.
Matherials and methods: Describes a case of a patient with an injury caused by a wooden foreign body. The circumstances of occurrence, ophthalmic and surgical actions taken in order to remove it were included. A lot of attention has been paid to prevention of intraocular infections.
Results: Patient did not find both post-traumatic and postoperative ophthalmic nerve injuries.
Summary: The most important for healing process is exact removal of the foreign body and prophylaxis of infections. In addition to treatment, it is important to educate the patient in the prevention of this type of injury
An odontoma causing a delay in teeth eruption in an 11-year old boy. Case report
Odontomas are the benign tumors, which are usually discovered by chance in radiographic images taken because of anomalies such as delayed eruption of teeth or malocclusion. Case study shows the course of diagnosis of an asymptomatic odontoma in youth, followed by a failure in teeth development
Dislocation of the mandible in a 47 year old patient
Dislocation of mandible is relatively uncommon disorder of temporomandibular joints. Disorder can occur during extreme dilation of mouth such as yawing, during dental treatments or endoscopic examination. 47- year old patient was admitted to the Department of Maxillo-facial Surgery in case of bilateral mandible dislocation. In this case the reposition in general anaesthesia was performed but ended up with failure
Dislocation of mandible in 48 year old patient - the continuation of a therapy
Dislocation of a temporomandible joint (TMJ) is a rare disfunction, which has multiform background divided into imbalance in the function of neuromascular component or structural deficit.
A 48-year-old woman was admitted to the Department of Maxillo-Facial Surgery of the Medical University of Lublin due to continuation of a treatment of TMJ dislocation. Previous hospitalization was performed a few months earlier. Reposition in general anaesthesia was used as a treatment, however it ended up with defeat. Current hospitalization with open surgery reposition was scheduled. Bilateral condylectomy was prosecuted. After surgery correct movability and proper anterior-posterior placement of mandible were achieved

Vascular structure of outer myometrial uterine leiomyomata : a preliminary sem and immunohistochemical study
Aim: The main goal of this study was assessment of vascular structure of uterine leiomyomata localized between outer myometrium and endometrium. Materials and Methods: The study was carried out on thirty two human uteri collected upon autopsy. Vessels were injected with synthetic resin, next corroded and coated with gold, finally observed using scanning electron microscope. Next ten uteri were injected with acrylic emulsion and studies using immunohistochemical staining for von Willebrandt’s factor. Results: Vascular structure of outer myometrial leiomyomata was quite similar to those observed in the middle of muscular layer of uterus, characterized by relatively dense ‘vascular capsule’, consisted of flattened vein, arterioles and capillaries. Conclusions: Structure of outer myometrial uterine leiomyomata was similar to those observed during growth within myometrium
