Wild boar populations up, numbers of hunters down? A review of trends and implications for Europe.

Across Europe, wild boar numbers increased in the 1960s-1970s but stabilised in the 1980s; recent evidence suggests that the numbers and impact of wild boar has grown steadily since the 1980s. As hunting is the main cause of mortality for this species, we reviewed wild boar hunting bags and hunter population trends in 18 European countries from 1982 to 2012. Hunting statistics and numbers of hunters were used as indicators of animal numbers and hunting pressure. The results confirmed that wild boar increased consistently throughout Europe, while the number of hunters remained relatively stable or declined in most countries. We conclude that recreational hunting is insufficient to limit wild boar population growth and that the relative impact of hunting on wild boar mortality had decreased. Other factors, such as mild winters, reforestation, intensification of crop production, supplementary feeding and compensatory population responses of wild boar to hunting pressure might also explain population growth. As populations continue to grow, more human-wild boar conflicts are expected unless this trend is reversed. New interdisciplinary approaches are urgently required to mitigate human-wild boar conflicts, which are otherwise destined to grow further.

Nutritional insight into preduodenal pouch reconstruction one year after total gastrectomy.

BACKGROUND: Various types of reconstructions have been developed to improve the quality of life of patients following total gastrectomy. In addition, to ensure larger food-intake reservoirs and extend meal transit times, different types of pouch reconstructions have been developed and described. Our opinion is that the most important factor in providing better physiologic regulation of ingested food is restoration of the duodenal passage and enlargement of the gastric substituent. MATERIALS AND METHODS: In the present study, we compared standard a Roux-en-Y reconstruction and a preduodenal pouch (PDP) reconstruction. We evaluated the quality of life (QoL) for 60 patients during the first postoperative year, comparing serum albumin, protein, hemoglobin, iron, body weight, body mass index, and QoL. QoL was defined according to Korenaga's score scale, which has 14 questions, for better understanding of subjective patient perceptions of digestive function. RESULTS: Our study population did not differ in iron and hemoglobin levels at a 1-y follow-up. The difference between total serum albumin level was significant in all observed patients in the follow-up period in favor of the PDP reconstruction group (P = 0.001). The PDP reconstruction group also had a significantly higher serum protein level after 12 mo. The higher score difference between the two groups generally confirm the improved QoL in the PDP group (P = 0.001). CONCLUSION: The most important aspects of improved QoL after gastrectomy due to gastric carcinoma are maintenance of the duodenal transit and the addition of a pouch. Jejunal preduodenal pouches provide a better QoL than Roux-en-Y reconstruction. Our study results suggest preduodenal pouch reconstruction should be used as the method of choice.

Early dumping syndrome and reflux esophagitis prevention with pouch reconstruction.

BACKGROUND: Total gastrectomy causes numerous disorders, such as reflux esophagitis, dumping syndrome, malabsorption, and malnutrition. To minimize the consequences, different variants of reconstruction are performed. The aim of our study is the comparison of two reconstructive methods: the standard Roux-en-Y and a new modality of pouch interposition, preduodenal-pouch interposition. This study aims to investigate the advantage of bile reflux prevention and to reduce symptoms of dumping syndrome after 3- and 6-mo follow-up. MATERIALS AND METHODS: A total of 60 patients were divided in two groups: (A) 30 patients with Roux-en-Y reconstruction, and (B) 30 patients with the preduodenal-pouch (PDP) type of reconstruction. Endoscopic examination and endoluminal jejunal limb pressure measurements were performed. Scintigraphic measurements of half-emptying time were performed to evaluate meal elimination in the context of reflux esophagitis and early dumping syndrome. The Japan Society of Gastrointestinal Surgery has provided guidelines with which to classify the symptoms of early dumping syndrome. Patients were followed up for periods of 3 and 6 mo after the surgery. RESULTS: Our study groups did not differ with regard to the level of reflux esophagitis (P = 0.688). Average values of pressure at 10 and 15 cm below the esophago-jejunal junction were significantly lower in the PDP group (P < 0.001). Elimination of the test meal between two groups was not significant (P = 0.222). Evaluation of early dumping syndrome symptoms revealed a significant reduction among PDP patients after 3 and 6 mo. CONCLUSION: Our study showed significant superiority of the new pouch reconstruction over the standard Roux-en-Y approach in the treatment of early dumping syndrome.

[Multifocal Abrikossoff's granular cell tumour of the oesophagus--case report].

INTRODUCTION: Granular cell tumours, relatively uncommon soft tissue tumours, have been a matter of debate among pathologists regarding histogenesis for a long time. Less common locations are in the aerodigestive tract including the oesophagus. CASE OUTLINE: We have recently treated a rare case, a 37-year-old male, who was admitted due to dysphagia and a painful swallow with occasional pharyngo-nasal regurgitation followed with a mild loss of weight. Standard clinical examination including X-ray chest, ECG and laboratory tests did not show pathological findings. Barium contrast oesophagography demonstrated multiple ovoid defects in the wall of the oesophagus. CT scan of the chest confirmed luminal narrowing owing to the tumour of the upper oesophagus. Upper endoscopy showed unusual multifocal nodular lesions alongside the oesophageal axis covered by smooth mucosa. A primary biopsy specimen taken from the largest nodules confirmed an unusual pathological finding of the granular cell tumour. Subtotal, transpleural oesophagectomy was performed and reconstruction was derived by long colon segment interposition through the posterior mediastinum. The postoperative course was uneventful. The operative specimen consisted of four ovoid tumours alongside the oesophagus (the greatest diameter 0.5-1.8, average 1.25). All verified tumours histologicaly consisted of a spindle-shaped or polygonal cells containing small and large eosinophilic granules and central nuclei. Most tumour cells showed strongly positive immunohistochemical staining for S-100 protein. These tumour cells were partially positive for p-53 and Ki-67. No lymph node metastases were detected histologically. CONCLUSION: Multifocal granular cell tumour of the oesophagus is an unusual finding with low incidence, and rarely caused symptoms. Pathological features and multiplicity of such tumours emphasized malignant predisposition requiring surgical resection of the oesophagus.
