Surgeons whose practice involves many infants and children should be acquainted with all abnormalities of pancreatic malformation and function. Conditions amenable to surgical treatment are few, but serious.Trauma to the pancreas in childhood is most commonly diagnosed by fever, leukocytosis, rectus spasm and elevated serum amylase. Drainage of the lesser sac and debridement of devitalized tissue may prevent the sequelae of pseudocyst formation which seems to follow the untreated injury. True congenital cysts are characterized by an epithelial lining.Mucoviscidosis complicated by meconium ileus remains a challenging disease of the newborn that requires early operation. Ten per cent of infants with cystic fibrosis may be threatened by intestinal obstruction from this cause. Some children surviving the newborn period go on to develop obstruction later.Annular malformation of pancreas may produce upper intestinal (duodenal) obstructive symptoms immediately after birth. Surgical correction by duodenojejunostomy should be postponed only long enough to correct severe fluid or electrolyte imbalances.Idiopathic spontaneous hypoglycemia has the most serious prognosis if convulsions are allowed to recur. Increased metabolic rates in infants increase the need for control of blood sugar levels by either administration of cortisone or pancreatic resection. If adenoma is the cause, a conservative resection of the tumor suffices. If serial frozen section fails to reveal either tumor or hypertophy of insulin-producing cells, blind pancreatectomy may be indicated, for irreversible brain damage develops early in uncontrolled hypoglycemia.  相似文献

ObjectiveTo report a case of Graves’ disease with concomitant sarcoidosis involving the thyroid gland.MethodsWe present the clinical, laboratory, imaging, and pathologic findings and describe the clinical course of a patient with Graves’ disease and sarcoidosis, who was unresponsive to propylthiouracil and radioiodine treatment.ResultsA 23-year-old woman presented with thyrotoxicosis and a large goiter. Laboratory studies and findings on thyroid uptake and scan were consistent with Graves’ disease. She was also found to have hilar lymph-adenopathy and hepatosplenomegaly. Despite treatment with antithyroid drugs and radioiodine therapy, her hyperthyroidism persisted. Surgical resection of the thyroid gland and 2 lymph nodes disclosed noncaseating granulomas, consistent with sarcoid.ConclusionAutoimmune endocrinopathies and, less commonly, thyroid autoimmune disease have been reported in patients with sarcoidosis. Similarities exist in the pathogenesis of these two conditions. Concomitant sarcoidosis in the thyroid gland in patients with Graves’ disease may contribute to the resistance to antithyroid drugs and radioiodine therapy. (Endocr Pract. 2007;13:159-163)  相似文献

ObjectiveTo describe a patient with untreated Cushing’s disease who had 2 spontaneous pregnancies that resulted in healthy babies on both occasions.MethodsWe present a case report with clinical, laboratory, and imaging data and discuss the literature pertaining to pregnancy in patients with Cushing’s syndrome.ResultsA 28-year-old woman came to our endocrinology clinic with a 1-year history of symptoms and signs of Cushing’s syndrome. An elevated 24-hour urinary cortisol excretion and an unsuppressed 1-mg overnight dexamethasone test confirmed the diagnosis. On her next visit, she reported a confirmed pregnancy, which ultimately resulted in the birth of a normal child. Further work-up subsequently showed 2 elevated 24-hour urinary cortisol values, loss of diurnal variation, and an elevated corticotropin level. There was lack of suppression on low-dose and high-dose overnight dexamethasone suppression tests. Magnetic resonance imaging of the pituitary showed normal findings. Inferior petrosal sinus sampling was recommended, but she declined the procedure. The patient returned 3 years later for reevaluation, at which time she reported the birth of another healthy child by cesarean delivery 10 months previously. There were no reported maternal or fetal complications. Examination at this visit revealed buccal pigmentation and proximal myopathy. Investigations showed increased 24-hour urinary cortisol excretion and serum corticotropin levels. Repeated magnetic resonance imaging disclosed a microadenoma on the right side of the pituitary. Unstimulated inferior petrosal sinus sampling showed a gradient to the right; thus, the presence of pituitary-dependent Cushing’s disease was confirmed.ConclusionOur case demonstrates that patients with pituitary-dependent Cushing’s disease are more likely to have spontaneous pregnancies with favorable outcomes than are patients with Cushing’s syndrome due to other causes. Our patient, despite having Cushing’s disease for more than 7 years, had 2 uneventful pregnancies that produced normal healthy children, without exacerbation of her disease during pregnancy.

Problems Associated with Biological Markers of Alzheimer’s Disease   总被引:3,自引:0,他引:3  
The etiopathogenesis of Alzheimer’s disease (AD) is still unclear, although clinical diagnostic criteria exist and the neuropathology of AD has been studied in great detail during the last 20 years. The present study addresses certain problems in the search for biological markers for the diagnosis, as well as in the follow-up of the course of AD and its differential diagnosis and reports some of our own observations in comparison with other studies. These include protein, genetic and neuroimaging markers. The definitions of biological markers and search strategies are also discussed. Special issue dedicated to Dr. Simo S. Oja  相似文献

The Guillain-Barré disease complex may result from a number of causes and have a wide variety of effects. The basic mechanism seems to be an immunizing or allergic reaction to many pathogens or their products, causing edema of the nerve roots in the spine, specifically about the meningeal covering. Resulting pressure on the axon causes nerve damage proportional to the severity and duration of pressure.Results in the 26 cases here reported and in other reports indicate that corticosteroids are the treatment of choice, the purpose being to reduce edema as promptly as possible. As might be expected, this therapy is of little value in the post-inflammatory stage of the disease, although prophylactic administration should continue for several months.Nerve and muscle rehabilitation are the chief aims of later treatment.  相似文献

Background

Radial nerve palsy associated with fractures of the shaft of the humerus is the most common nerve lesion complicating fractures of long bones. However, the management of radial nerve injuries associated with humeral fractures is debatable. There was no consensus between observation and early exploration.

Methods and Findings

The PubMed, Embase, Cochrane Central Register of Controlled Trials, Google Scholar, CINAHL, International Bibliography of the Social Sciences, and Social Sciences Citation Index were searched. Two authors independently searched for relevant studies in any language from 1966 to Jan 2013. Thirty studies with 2952 humeral fractures participants were identified. Thirteen studies favored conservative strategy. No significant difference between early exploration and no exploration groups (OR, 1.03, 95% CI 0.61, 1.72; I2 = 0.0%, p = 0.918 n.s.). Three studies recommend early radial nerve exploration in patients with open fractures of humerus with radial nerve injury. Five studies proposed early exploration was performed in high-energy humeral shaft fractures with radial nerve injury.

Conclusions

The conservative strategy was a good choice for patients with low-energy closed fractures of humerus with radial nerve injury. We recommend early radial nerve exploration (within the first 2 weeks) in patients with open fractures or high-energy closed fractures of humerus with radial nerve injury.  相似文献

Objective

Teachers'' attitudes toward inclusion are often based on the practical implementation of inclusive education rather than a specific ideology and understanding of inclusiveness. This study aimed to identify the factors associated with primary school teachers'' attitudes towards inclusion of students with all disabilities in regular schools.

Method

Seventy four primary school teachers participated in a cross-sectional survey conducted in Western Australia. Teachers'' attitudes and efficacy toward integration of students with disabilities were measured using the Opinions Relative to Integration of Students with Disabilities scale and Bandura''s Teacher Efficacy scale respectively.

Results

Four teacher attributes—age, gender, teaching self-efficacy and training collectively explained 42% of the variability in teachers'' attitude toward including students with disabilities.

Conclusion

The current study further contributes to the accumulation of knowledge that can unpack the complex pattern of factors that should be considered to promote positive attitudes towards inclusive schools.  相似文献
