Abstract Cementoblastoma is a rare, benign, expansive and slow-growing, mesenchymal odontogenic tumor. An eight year-old, Purebred Spanish Horse stallion with clinical history of chronic, refractory to treatment unilateral rhinitis and radiologic evidence of a radiopaque mass at the second premolar tooth root underwent intraoral surgery for tooth and mass extraction. The owner did not want to bear the cost of the histopathologic study and the samples were left unattended in a sterile recipient without a fixative solution for six years. Grossly the mass showed a hard consistence, greyish-whitish color and an irregular surface. Histologically, the mass consisted of an abundant deposit of eosinophilic cementum-like organic matrix with frequent basophilic reversal lines and heterogeneous distribution of empty lacunae. Surrounded by this organic matrix there were numerous fungal hyphae positive for Aspergillus fumigatus immunostaining. The final diagnosis was maxillary cementoblastoma with secondary aspergillosis. High-quality information has been obtained from long-time non-fixed tissues.

The accurate knowledge of Heat Transfer Coefficients is essential for the design of precise heat transfer operations. The determination of these values requires Inverse Heat Transfer Calculations, which are usually based on heuristic optimisation techniques, like Genetic Algorithms or Particle Swarm Optimisation. The main bottleneck of these heuristics is the high computational demand of the cost function calculation, which is usually based on heat transfer simulations producing the thermal history of the workpiece at given locations. This Direct Heat Transfer Calculation is a well parallelisable process, making it feasible to implement an efficient GPU kernel for this purpose. This paper presents a novel step forward: based on the special requirements of the heuristics solving the inverse problem (executing hundreds of simulations in a parallel fashion at the end of each iteration), it is possible to gain a higher level of parallelism using multiple graphics accelerators. The results show that this implementation (running on 4 GPUs) is about 120 times faster than a traditional CPU implementation using 20 cores. The latest developments of the GPU-based High Power Computations area were also analysed, like the new NVLink connection between the host and the devices, which tries to solve the long time existing data transfer handicap of GPU programming.

Wall Tumor

Desmoid tumors (also called desmoids fibromatosis) are rare slow growing benign and musculoaponeurotic tumors. Although these tumors have a propensity to invade surrounding tissues, they are not malignant. These tumors are associated with women of fertile age, especially during and after pregnancy and postoperative surgeries. Our clinical case is interesting because of the rarity of the pathology and the difficulties in setting the correct diagnosis. The patient, with a history of laparoscopic myomectomy (2012), was preparing for a routine surgery for the endometrioma of the anterior abdominal wall, according to the results of the ultrasound and computed tomography. After surgical treatment, the final diagnosis was changed, based on the histological findings. Key words: desmoid tumor, abdominal wall tumor, fibroid.

We report the case of a seventy-four-year-old man with a slow-growing 2 cm mass on the back that arose near the surgical scar of previously excised melanoma, invasive to a Breslow depth of 3 mm. Preoperative clinical diagnosis was “in-transit” melanoma metastasis. After surgical excision, histopathologic examination revealed a dermal nodular proliferation of spindle cells arranged in storiform pattern, with mild pleomorphism, infiltrating around appendages and into the subcutaneous tissue. Immunohistochemical investigation documented diffuse positivity for CD34 and vimentin of spindle cells. Scattered dendritic cells, containing dark pigment in varying proportion and positive for S100, Melan-A and HMB-45, were also observed. A final diagnosis of Bednar tumour was formulated. Subsequently, the patient developed numerous metastases from the primary melanoma and died after 18 months. Bednar tumour is a rare pigmented variant of dermatofibrosarcoma protuberans of intermediate malignant potential. The presence of pigmented cells in Bednar tumour requires careful differential diagnosis with malignant or benign pigmented skin tumours. The clinical history of a Bednar tumour developing close to the scar of a previous melanoma gives the opportunity of a critical and intriguing discussion about the potential origin of pigmented cells in this rare variant of dermatofibrosarcoma protuberans.

Background: Primary tracheal adenoid cystic carcinoma is a rare, slow-growing pulmonary malignancy. Due to the low incidence, clinicians are poor in the diagnosis and treatment of such disease, which is prone to cause misdiagnosis or missed diagnosis, consequently leading to delayed treatment. Case Presentation: Here, we reported a case of a 72-year-old woman who was diagnosed as primary bronchial adenoid cystic carcinoma after three years. At the time of final diagnosis, lesion involvement was seen in the entire bronchus and radical treatment was not available. Conclusions: Endoscopic bronchoscopy and palliative radiotherapy can relieve the symptoms of the patient and make the patient survive with the tumor for a long time.

Object Noninvasive neuroimaging techniques are increasingly identifying unruptured intracranial arterial dissections (IADs) at examination for headache or ischemic symptoms. Approximately 3% of cases of aneurysmal subarachnoid hemorrhage (SAH) are caused by IADs in Japan, but the natural history of unruptured IADs is not known. Methods Clinical data obtained in 190 patients with 206 IADs were retrospectively analyzed on the basis of long-time follow-up of geometry and clinical event. The IADs were divided into an unruptured group and SAH group depending on the patient's clinical status at the initial diagnosis. Day 0 was defined as the day preceding diagnosis of IAD—that is, the day of symptom onset. This was retrospectively determined from the clinical history. Results The 206 IADs included 98 unruptured lesions and 108 SAH. In both groups, the vertebral artery was the most frequent site. In the unruptured group, 93 IADs were followed for a mean of 3.44 years. The mean interval between symptom onset (Day 0) and neuroimaging diagnosis was 9.8 days. Subsequent geometry change was seen in 78 (83.9%) of 93 IADs. Major change was almost completed within 2 months, and complete normalization was seen on neuroimaging in 17 (18.3%) of 93 IADs, with the earliest on Day 15. Rupture of the IAD in the unruptured group occurred in only 1 patient on Day 11. In the SAH group, 84 of the 108 patients complained of preceding headache before onset of SAH. In 81 (96.4%) of the 84 patients, SAH occurred on Day 0–3 with the latest on Day 11. In all patients in the unruptured and SAH groups, the latest day of SAH from the onset of preceding headache was Day 11. Conclusions Most IADs causing SAH bleed within a few days of occurrence. Most IADs that are unruptured already have little risk for bleeding at diagnosis because of the repair process. Intracranial arterial dissections may be much more common than previously thought, and the majority may occur and heal without symptom manifestation.

Abstract Background: Dizziness is a relatively common symptom among patients who call for the emergency medical service (EMS).Methods: All patients assessed by the EMS and triaged using the rapid emergency triage and treatment system for adults code 11 (=dizziness) in the 660,000 inhabitants in the Municipality of Gothenburg, Sweden, in 2016, were considered for inclusion. The patients were divided into two groups according to the final diagnosis (a time-sensitive condition, yes or no).Results: There were 1,536 patients who fulfilled the inclusion criteria, of which 96 (6.2%) had a time-sensitive condition. The majority of these had an acute cerebrovascular disease. Eight predictors of a time-sensitive condition were identified. Three were associated with a reduced risk: 1) the dizziness was of a rotatory type, 2) the dizziness had a sudden onset and 3) increasing body temperature. Five were associated with an increased risk: 1) sudden onset of headache, 2) a history of head trauma, 3) symptoms of nausea or vomiting, 4) on treatment with anticoagulants and 5) increasing systolic blood pressure.Conclusion: Among 1,536 patients who were assessed by the EMS due to dizziness, 6.2% had a time-sensitive condition. On the arrival of the EMS, eight factors were associated with the risk of having a time-sensitive condition. They were linked to the type of symptoms, to clinical findings on the arrival of the EMS and to the recent clinical history.

Abstract Background Dizziness is a relatively common symptom among patients who call for the emergency medical services (EMS). Aim To identify factors of importance for the early identification of a time-sensitive condition behind the symptom of dizziness among patients assessed by the EMS. Methods All patients assessed by the EMS and triaged using Rapid Emergency Triage and Treatment (RETTS) for adults code 11 (=dizziness) in the 660,000 inhabitants in the Municipality of Gothenburg, Sweden, in 2016, were considered for inclusion. The patients were divided into two groups according to the final diagnosis (a time-sensitive condition, yes or no). Results There were 1536 patients who fulfilled the inclusion criteria, of which 96 (6.2%) had a time-sensitive condition. The majority of these had a stroke/transitory ischaemic attack (TIA). Eight predictors of a time-sensitive condition were identified. Three were associated with a reduced risk: 1) the dizziness was of a rotatory type, 2) the dizziness had a sudden onset and 3) increasing body temperature. Five were associated with an increased risk: 1) sudden onset of headache, 2) a history of head trauma, 3) symptoms of nausea or vomiting, 4) on treatment with anticoagulants and 5) increasing systolic blood pressure. Conclusion Among 1536 patients who were triaged by the EMS for dizziness, 6.2% had a time-sensitive condition.

Introduction. The organization of transport links and the bridge building in cities located on the banks of wide rivers has always been one of the most important tasks of the local administration. The study of the history of bridge building allows not only to trace the process of modernization of different regions of the country, but also to help in solving similar problems of our time. Nevertheless, the history of Russian bridge building is poorly studied. The purpose of the article is to determine the characteristics and features of the organization of bridge building in big cities of the European North of Russia as a way to solve one of the problems of urban infrastructure in the early XX century. Materials and Methods. The sources for this study are the documents of the State archive of the Arkhangelsk region, published documents on the history of Vologda, articles in the local periodicals of the early XX century. The analysis of the studied problem used a systematic approach, the method of economic analysis, historical and historical-comparative methods. Results and Discussion. The building of permanent bridges was a need for the development of Arkhangelsk and Vologda. In Vologda the two wooden bridges were built in the middle of XIX century on city funds and in the future these bridges were repaired or rebuilt. The Arkhangelsk city authorities did not hurry to solve a problem of city infrastructure by own efforts and a long time they used the floating bridge. The lack of experience in the building of large bridges and the desire to save money led to the rapid destruction of the first permanent bridge in Arkhangelsk. Conclusion. The Development of trade and industry in cities of the European North of Russia, such as Arkhangelsk and Vologda, led to the expansion of their territory and the emergence over time, the so-called third parts of the cities. Despite the comparable size of the population of the districts located across the river, the process of connecting them with bridges to the rest of the city went at different rates, which depended on the attitude of the local administration to the problem of urban infrastructure.

Background: Serum Peanut-specific-IgE (PN-sIgE) and peanut-component-resolved-diagnostics (CRD) are often ordered simultaneously in the evaluation for peanut allergy. Results often guide the plans for peanut oral challenge. However, the clinical utility of CRD at different total PN-sIgE levels is unclear. A commonly used predefined CRD Ara h2 cutoff value in the literature predicting probability of peanut challenge outcomes is 0.35kUA/L. Objective: To examine the utility of CRD in patients with and without a history of clinical reactivity to peanut (PN). Methods: This was a retrospective chart review of 196 children with PN-sIgE and CRD testing, of which, 98 patients had a clinical history of an IgE-mediated reaction when exposed to PN and 98 did not. The Fisher's exact test was used to assess the relationship between CRD and PN-sIgE at different cutoff levels, McNemar test and Gwet’s approach (AC1 statistic) were used to examine agreement between CRD and PN-sIgE, and logistic regression was used to assess differences in the findings between patients with and without reaction history. Results: Ara h 1, 2, 3, or 9 (ARAH) levels ≤0.35 kUA/L were significantly associated with PN-sIgE levels <2 kUA/L rather than ≥2 kUA/L (p < 0.0001). When the ARAH threshold was increased to 1 kUA/L and 2 kUA/L, these thresholds were still significantly associated with PN-sIgE levels of <2, <5, and <14 kUA/L. These findings were not significantly different in patients with and without a history of clinical reactivity. Conclusion: ARAH values correlated with PN-sIgE. Regardless of clinical history, ARAH levels are unlikely to be below 0.35, 1, or 2 kUA/L if the PN-sIgE level is >2 kUA/L. Thus, if possible, practitioners should consider PN-sIgE rather than automatically ordering CRD with PN-sIgE every time. Laboratory procedures that allow automatically and reflexively adding CRD when the PN-sIgE level is ≤5 kUA/L can be helpful. However, further studies are needed in subjects with challenge-proven PN allergy.

In a very short period of time, “COVID-19” has seized the consciousness globally by making remarkable changes in our day to day living and has superintended as a public health emergency globally. It has high radar of transmission, affecting an individual at work to frontline workers. The measures and planning for a response plays a key role from drawing up an emergency committee and this follows an equation which broadly deals with epidemiological to clinical history of the patient, management steps from isolation, screening, diagnostic assays for identification and treatment. The application of an organized plan with secure structure aids in better performance, increases efficacy of management and saves time. Also saves time for a health care worker to g through routine levels of channels of administration if already a familiar way of operation is known for such situations. Thus, planning and developing a ‘blueprint of approach’ towards management of patient while facing such situation is a must. This review provides an insight to the measures for detection, response and preparedness of the hospital and health care workers should largely be inclusive of; also highlights the measures to be taken at every step after coming in contact with a positive case of “COVID-19”.
