RESUMO

The objective of this paper is to present the technical and feasibility analysis of an innovative mechanical recycling system for exhausted coffee capsules. This recycling process involved the sorting of spent coffee grounds (SGC) and the subsequent drying and melt-mixing of a portion of these grounds with the remaining capsule components, mainly composed of polypropylene (PP), along with optional virgin PP. These newly developed composite materials exhibited mechanical and rheological properties comparable or even surpassing those of virgin PP. They were also successfully utilized for the injection of new capsule shells, thus alignin with the principles of the circular economy. In addition to the technical aspects, this paper present a comprehensive Techno-Economic Analysis (TEA) of the proposed recycling processes, considering the inclusion of virgin PP (0-20 %) and the initial moisture content (MSGC) of SGC(5-55 %) as varying factors. An industrial plant, designed to handle up to 190 million exhausted coffee capsules and produce up to 1500 tons of recycled compund was appropriately sized. The analysis revealed that processes are profitable across all examined scenarios and that the Net Present Value ranged between 800 k€ (for vPP = 20 % and MSGC = 55 %) and 2000 k€ (for vPP = 0 % and MSGC = 5 %).

RESUMO

Lipoblastoma is a rare and benign tumour arising from embryonal fat cells, predominantly diagnosed in children younger than 3 years old. The most frequent locations are the extremities and trunk, while the head and neck areas are more rarely affected (10-15% of total cases). Clinically, the most common presentation is a fast-growing painless mass. Ultrasound is the first-line imaging examination, but Magnetic Resonance Imaging (MRI) allows for better definition of the relationships with the adjacent vascular and muscular structures. It can help to identify the lipomatous components, and it is useful for preoperative planning. However, the definitive diagnosis is provided by histopathological examination. Complete surgical excision is the first-line treatment, with a good prognosis in case of total eradication. We report the case of a 7-month-old male child with a rapidly growing mass that had typical radiological features of lipoblastoma.

RESUMO

Wetlands are being increasingly affected by anthropogenic activities worldwide. The Lower Delta of the Paraná River, one of the most important wetlands in Argentina, has been profoundly altered because most of the natural environments were drained or diked to make them suitable for different agricultural activities. As a result, the landscape is characterized by a mosaic of Salicaceae afforestations of different ages interspersed with patches of secondary forests and grazing grasslands. The high susceptibility of Carabidae and Aphodiidae to natural and human-induced disturbances and management practices is reflected by changes in their spatiotemporal distribution. We performed a 1-year study to analyze and compare beetle's communities inhabiting different habitat types in this modified wetland landscape. A total of 58 beetle species were recorded, of which 48 were carabids and 10 aphodids. Although species richness and diversity were higher in productive habitats (afforestations and grasslands) than in secondary forests, hydrophilic species were only found in the latter. Community parameters varied seasonally. Our results indicate a close relationship between wetland beetle communities and vegetation cover in each habitat type. Human activity increases heterogeneity across this landscape, which favors the colonization of new species but causes the loss or displacement of autochthonous species. The secondary forests could serve as alternative habitats for beetles typical of humid environments. We propose the maintenance of the current heterogeneous mosaic to favor the diversity of ground beetles and the implementation of changes in water management for the benefit of hydrophilic beetle species.

RESUMO

Hydatid Disease (HD), also called Echinococcosis or Hydatidosis, is a parasitic infection caused by the larval stage of the tapeworm Echinococcus: E. granulosus or E. multilocularis. HD occur most frequently in liver or lungs, rarely in brain, skeletal muscles, bones, kidneys, spleen. Bone infestation of Echinococcosis hydatid cysts occurs respectively by haematogenous seeding and progressive invasion into bone by lesions in the adjacent soft tissues. Patients with musculoskeletal HD clinically show the disease in adulthood because the lesions develop very slowly. In some cases, HD is an uncommon cause of soft tissue mass, pain and neurovascular symptoms due to compression or to secondary infection. Diagnostic imaging plays an important role in the diagnosis of HD and in the differential diagnosis with soft tissue tumors. We present a rare case of male patient of 42 year-old with diagnosis of HD with primary and exclusive localization in right hemi-pelvis and femur.

RESUMO

Until 2009, bovine besnoitiosis had never been considered endemic in Italy and the only report on the disease in this country referred to animals imported from France shortly before. However, recently, an autochthonous outbreak of bovine besnoitiosis was reported in four herds located at the intersection of the borders between Emilia-Romagna, Toscana and Marche (Northern Apennine Mountains), which has led to an increased awareness concerning this disease. The present study describes a further outbreak of bovine besnoitiosis in Italy. The afflicted herd was a dairy herd with no evidence for contact with cattle from regions known to be endemic for bovine besnoitiosis. The farm investigation was initiated after a three-year old Holstein Friesian dairy cow with generalized thickening and lichenification of the skin was diagnosed with bovine besnoitiosis. The clinical diagnosis was confirmed by gross pathology, histopathology, serology and PCR. Bradyzoites released from tissue cysts obtained from the skin of this animal enabled the first in vitro isolation of Besnoitia besnoiti in Italy. This isolate was named Bb-Italy1. Sequencing of a 2118 bp spanning region including the complete internal transcribed spacer 1 and parts of the 18S and the 5.8S rRNA gene from DNA extracted from skin-derived zoites revealed a 99.9% identity to sequences known for other B. besnoiti isolated from cattle in Europe. Two GKO mice which had been inoculated intraperitoneally with bovine skin-derived bradyzoites became ill 7 days post inoculation. Parasitophorous vacuoles with multiplying zoites were observed in the cell culture inoculated with peritoneal fluids of these mice and a B. besnoiti infection in the mice and in the cell culture could be confirmed by real-time PCR. A serological investigation in the afflicted herd using immunoblots and an immunofluorescent antibody test (IFAT) revealed an overall herd seroprevalence of 9.7% (31/321), whereas within the female animals older than 2 years 17.0% (29/171) of the dams were tested positive. With one exception, an imported cow from Germany, all the seropositive animals were born in Italy. In connection with previously described autochthonous cases of bovine besnoitiosis the case described herein suggests that bovine besnoitiosis should be considered endemic in Italy.

RESUMO

In May and July 2010 and in March 2011, the presence of multiple bleeding nodules at the level of the neck, shoulders, withers, back and rump in five cattle from three herds in north-central Italy were observed. A diagnosis of parafilariosis was made. Fragments of adult females of Parafilaria bovicola could be identified from the derma of three to five bioptic extirpates. Larvated eggs and free larvae were observed in serohemorrhagic exudates. This paper is the first report of the occurrence of parafilariosis in Italy and subsequent to the various outbreaks reported, it can now be said that bovine parafilariosis is also currently present in Italy.

RESUMO

This paper reports the results of an integrated assessment of traffic impact on a tourist-popular high altitude region which includes mountain passes and road tunnels. A modeling system for air quality assessment and management has been established and revised. The system has been used to evaluate the impact of traffic due to the re-opening of the Mont Blanc tunnel: the increase in NO(x) concentrations ranges from 50% at the bottom of the upper valley to 150% near to tunnel entrance.

RESUMO

BACKGROUND: Transcutaneous oximetry was studied to select the correct amputation level for limb ischemic necrosis with possible identification of threshold value. METHODS: The method was evaluated in 30 cases (20 patients, 5 males and 15 females, of ages ranging from 61 to 93, average 73.1+/-8.5) where patients underwent amputation because of severe leg ischemia. Surgical operations were: minor amputation (toe or transmetatarsal) in 23 cases, below knee amputation in 7. Oxygen tension was measured at the dorsum foot and at the third superior of the anteromedial calf aspect. RESULTS: Results were classified as success (primary or delayed healing) or failure (necrosis at the surgical wound). Amputation was successful in 17/30 cases with oxygen tension of 0-65 mmHg (mean 32.5+/-16.1) and failed in 13/30 with oxygen tension of 0-57 mmHg (mean 7.8+/-17.3). The difference was statistically significant (p=0.0004). Sensitivity of the method resulted 88.2%, specificity 84.6%, diagnostic accuracy 86.7%, positive predictive value 88.2% and negative predictive value 84.6%. A threshold of 20 mmHg was identified: 15/17 successful cases showed values greater than 20 mmHg, while 11/13 failed cases presented values lower than the threshold. CONCLUSIONS: Following our observations and according to some reported studies, we believe transcutaneous oximetry to be the best method for selection of amputation level This is a simple, noninvasive and accurate method, which has showed itself superior to other techniques (i.e., Doppler and radioisotope).

RESUMO

BACKGROUND: Patients who have an acute subdural hematoma with a thickness of 10 mm or less and with a shift of the midline structures of 5 mm or less often can be treated nonoperatively. We wonder whether the knowledge of the clinical status both in the prehospital determination and on admission to the neurosurgical center can predict the need for evacuation of subdural hematomas as well as the computed tomographic (CT) parameters. METHODS: From January 1, 1994, to May 31, 1996, 65 comatose patients harboring an acute subdural hematoma of 5 mm or more and not brain dead were admitted to our intensive care unit. Of the 65 patients, 15 patients were initially managed conservatively according to a protocol based on clinical, CT, and intracranial pressure parameters. During the study period, the use of long-lasting paralytic agents has been eliminated to allow detection of clinical deterioration in the Glasgow Coma Scale (GCS) score from the prehospital determination to the hospital admission assessment. RESULTS: Of the 15 patients initially managed conservatively, two were subsequently operated on because of evolving parenchymal hematomas. When comparing demographic, clinical, and CT parameters between the surgical group of patients and the patients initially conservatively treated, hematoma thickness (mean, 17.1 mm vs. 7.5 mm, p < 0.0001) and shift of the midline structures (mean, 12.8 mm vs. 4.7 mm, p < 0.008) were predictive of the need for surgery. A statistically significant change in the GCS score between prehospital determination and admission assessment was shown in the surgical group of patients (mean GCS score, 8.4 vs. 6.7, p < 0.01), and it was not present (mean GCS score, 7.3 vs. 7.2) in the patients initially conservatively treated. Functional outcomes were present in 23 cases (35.4%); functional outcomes in the initially conservatively treated patients were reached by 10 patients (66.7%). CONCLUSIONS: Nonoperative management for selected cases of acute subdural hematomas is at least as safe as surgical management. GCS scoring at the scene and in the emergency room combined with early and subsequent CT scanning is crucial when making the decision for nonoperative management. This strategy requires that administration of long-lasting sedatives and paralytic medications be avoided before the patient arrives at the neurosurgical center.

RESUMO

BACKGROUND: The incidence of the associated risk factors on the early results of elective repair of abdominal aortic aneurysms has been evaluated in a series of 270 consecutive patients. Clinical, hematological and instrumental data concerning cardiovascular, pulmonary and metabolic diseases have been collected for each patient, as well as the type and the results of the surgical procedure. METHODS: The graft was straight aortic in 82 cases (30.3%), aorto-bisiliac in 130 (48.1%) and aorto-bifemoral in 58 cases (21.6%); the 237 uneventful patients (87.8%) have been discharged 8 days after the operation (mean) and 24 (8.9%) underwent to coronary-aortic bypass graft (CABG) previously. RESULTS: Postoperative complications have been observed in 33 patients (12.2%): 24.3% pulmonary, 21.2% cardiac and 15.1% renal and among these 13 patients died (4.8% of the complete series and 39.4% of those with complications) because of pulmonary (38.4%), cardiac (30.7%) and renal causes (23.3%) mainly. Despite the complications occurred mainly in patients with associated risk factors, the multivariate analysis has shown that only the chronic obstructive pulmonary disease (COPD) plays a fundamental role (p < 0.005). On the contrary, among the patients died not one single risk factor reached statistical significance, although the COPD was close (p = 0.1). CONCLUSIONS: These data underline the need of a careful evaluation and treatment of associated diseases in patients undergoing elective repair for an AAA; namely a screening for asymptomatic coronary artery disease, since the CABG can significantly reduce morbility and mortality rates, and for COPD. In addition a more careful monitoring of patients with long clamping time could reduce the possible related renal complications. Up to now, since the surgical procedures is already standardized, the precise diagnosis and treatment of associated risk factors represent the winning strategy for the achievement of better results.

RESUMO

From January 1, 1990, to April 30, 1994, 412 patients were admitted to our intensive care unit in coma after head injuries. Our study group consisted of 37 patients who were retrospectively identified as harboring lesions or developing new lesions within a 12-hour period from the time of admission. We defined the evolution of a lesion as an increase or decrease in the size of an already present hematoma or as the appearance of a totally new lesion. There were 25 male and 12 female patients (mean age, 34.9 yr), and the cause of trauma was road traffic accidents in 32 patients. Nine patients presented with shock, and six had evidence of abnormal coagulation at admission. Patients were divided into two different groups. In Group 1, 15 patients harbored lesions that evolved toward reabsorption. In Group 2, 22 patients harbored hematomas that evolved toward lesions requiring surgical removal. Fifteen of these patients had initial diagnoses of diffuse injury that evolved in this manner, whereas the remaining seven patients had already been operated upon and had developed second, noncontiguous, surgical lesions. Patients with lesions that required surgical evacuation had their computed tomographic (CT) scans obtained earlier and had a higher incidence of clinical deterioration. There was a significant difference in the evolution of the different lesions (P < 0.001), with subdural hematomas being more prone to reabsorption and intracerebral and extradural hematomas being more likely to increase in size or to appear as new lesions. Second CT scans were obtained because of clinical deterioration in 10 patients and because of increase in intracranial pressure in 5 patients. Scheduled CT scans were obtained in 13 patients, whereas in the remaining 9 patients, the diagnosis emerged from a combination of scheduled CT scans and intracranial pressure monitoring. There was a trend toward a poorer result among the patients with clinical deterioration, which, however, was not significant. A significant proportion of post-traumatic patients, particularly those who are unconscious, harbor early evolving intracranial lesions. When the first CT scan is performed within 3 hours after injury, a CT scan should be repeated within 12 hours.

RESUMO

The AA. describe two cases of serious juvenile myasthenia arisen after jennerian vaccination, antidiphteric and antitetanic vaccination in the first patient and after antitetanic vaccination in the second one. They put forward the hypothesis that in the two patients juvenile serious myasthenia is a complication due to vaccination for the following reasons: 1) the chronological relation between vaccination and the arising of myasthenic sumptomatology is very close; 2) the vaccine produces in the body a reaction of immunity type and myasthenia is nowadays generally considered as an immunity disease. Although the ways in which the vaccine inoculation can give rise to the disease are unknown, it can be supposed that in the occurrence at the same time of a genetic factor or of an susceptible area, the vaccine can act as a factor provoking the immunity answer of myasthenic type.
