Two-Stage Treatment of Enterocutaneous Fistulas

Aim: to determine the most efficient treatment of enterocutaneous fistulas.Materials and methods. Eighty-eight patients with intestinal fistulas underwent a two-stage treatment, including: the first stage — multicomponent therapy, the second stage — reconstructive surgery. Enterocutaneous fistulas were diagnosed in 61 patients, enteroatmospheric fistulas — in 26 patients, and combined fistula (enterocutaneous and enteroatmospheric) — in 1 patient.Results. All 88 patients underwent reconstructive surgery after the multicomponent therapy. Resection of the intestine with a fistula with the formation of an entero-entero anastomosis was performed in 72 (81.8 %) patients; marginal resection of the intestine with a fistula, followed by suturing of the defect — in 7 (8.0 %); resection of the intestine with fistulas in combination with excision and suturing of the fistula — in 5 (5.7 %); an operation aimed at disabling the fistula from the passage of intestinal contents — in 3 (3.4 %); resection of the intestine with a fistula in combination with fistula exclusion — in 1 (1.1 %) patient. Postoperative complications in the group of patients with enteroatmospheric fistulas occurred in 13 cases, in the group with enterocutaneous fistulas — in 25 patients. Three (3.4 %) patients with enterocutaneous fistulas died from complications unrelated to the underlying disease and surgical interventions.Conclusion. Two-stage treatment including multicomponent therapy (nutritional support, infection generalization control, local wound treatment) and reconstructive surgery allowed to reduce mortality rates to 3.4 %, which proves the effectiveness of this method

Secondary education reform in Lesotho and Zimbabwe and the needs of rural girls: Pronouncements, policy and practice

Analysis of the educational needs of rural girls in Lesotho and Zimbabwe suggests a number of shortcomings in the current form of secondary education, and ways in which it might be modified so as to serve this sizeable group of students better. Several of the shortcomings, notably in relation to curricular irrelevance and excessive focus on examinations, have long been recognised, including by politicians. Yet political pronouncements are seldom translated into policy, and even where policy is formulated, reforms are seldom implemented in schools. This paper makes use of interviews with educational decision-makers in the two southern African countries and a range of documentary sources to explore why, despite the considerable differences between the two contexts, much needed educational reforms have been implemented in neither

Is Chytridiomycosis an Emerging Infectious Disease in Asia?

The disease chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), has caused dramatic amphibian population declines and extinctions in Australia, Central and North America, and Europe. Bd is associated with >200 species extinctions of amphibians, but not all species that become infected are susceptible to the disease. Specifically, Bd has rapidly emerged in some areas of the world, such as in Australia, USA, and throughout Central and South America, causing population and species collapse. The mechanism behind the rapid global emergence of the disease is poorly understood, in part due to an incomplete picture of the global distribution of Bd. At present, there is a considerable amount of geographic bias in survey effort for Bd, with Asia being the most neglected continent. To date, Bd surveys have been published for few Asian countries, and infected amphibians have been reported only from Indonesia, South Korea, China and Japan. Thus far, there have been no substantiated reports of enigmatic or suspected disease-caused population declines of the kind that has been attributed to Bd in other areas. In order to gain a more detailed picture of the distribution of Bd in Asia, we undertook a widespread, opportunistic survey of over 3,000 amphibians for Bd throughout Asia and adjoining Papua New Guinea. Survey sites spanned 15 countries, approximately 36° latitude, 111° longitude, and over 2000 m in elevation. Bd prevalence was very low throughout our survey area (2.35% overall) and infected animals were not clumped as would be expected in epizootic events. This suggests that Bd is either newly emerging in Asia, endemic at low prevalence, or that some other ecological factor is preventing Bd from fully invading Asian amphibians. The current observed pattern in Asia differs from that in many other parts of the world

Clinical Guidelines of the Russian Society of Surgeons, the Russian Gastroenterological Association, the Association of Surgeons-Hepatologists and the Endoscopic Society “REndO” on Diagnostics and Treatment of Chronic Pancreatitis

Aim: to present modern methods of diagnosis and treatment of chronic pancreatitis for gastroenterologists, general practitioners and physicians.Chronic pancreatitis (CP) is a long-term inflammatory disease of the pancreas, manifested by irreversible morphological changes in the parenchyma and pancreatic ducts, which cause pain and/or persistent impairment of function. Current concept on the etiology of CP is reflected by the TIGAR-O classification. The criteria for establishing the diagnosis of CP include typical attacks of abdominal pain and/or clinical and laboratory signs of exocrine, endocrine insufficiency with the mandatory detection of characteristic morphological changes (calcifications in the parenchyma and pancreatic ductal stones, dilatation of the main pancreatic duct and its branches). CT, MRCP, and pancreatobiliary endosonography are recommended as the methods of choice to verify the diagnosis of CP. Conservative treatment of patients with CP is provided for symptom relief and prevention of complications. Individual cases with severe non-interactable abdominal pain, as well as a complicated course of the disease (development of ductal hypertension due to main pancreatic duct stones or strictures, obstructive jaundice caused by compression of the common bile duct, symptomatic postnecrotic cysts, portal hypertension due to compression of the portal vein or thrombosis of the splenic vein, persistent duodenal obstruction, pseudoaneurysm of the celiac trunk basin and the superior mesenteric artery) serve as an indication for endoscopic or surgical treatment. The Guidelines set out modern approaches to the diagnosis, conservative, endoscopic and surgical treatment of CP, and the prevention of its complications.Conclusion. The implementation of clinical guidelines can contribute to the timely diagnosis and improve the quality of medical care for patients with chronic pancreatitis

Nothing a Hot Bath Won't Cure: Infection Rates of Amphibian Chytrid Fungus Correlate Negatively with Water Temperature under Natural Field Settings

Dramatic declines and extinctions of amphibian populations throughout the world have been associated with chytridiomycosis, an infectious disease caused by the pathogenic chytrid fungus Batrachochytrium dendrobatidis (Bd). Previous studies indicated that Bd prevalence correlates with cooler temperatures in the field, and laboratory experiments have demonstrated that Bd ceases growth at temperatures above 28°C. Here we investigate how small-scale variations in water temperature correlate with Bd prevalence in the wild. We sampled 221 amphibians, including 201 lowland leopard frogs (Rana [Lithobates] yavapaiensis), from 12 sites in Arizona, USA, and tested them for Bd. Amphibians were encountered in microhabitats that exhibited a wide range of water temperatures (10–50°C), including several geothermal water sources. There was a strong inverse correlation between the water temperature in which lowland leopard frogs were captured and Bd prevalence, even after taking into account the influence of year, season, and host size. In locations where Bd was known to be present, the prevalence of Bd infections dropped from 75–100% in water <15°C, to less than 10% in water >30°C. A strong inverse correlation between Bd infection status and water temperature was also observed within sites. Our findings suggest that microhabitats where water temperatures exceed 30°C provide lowland leopard frogs with significant protection from Bd, which could have important implications for disease dynamics, as well as management applications
