Neurofibromatosis type 1 (NF1) is an autosomal dominant multisystem disorder affecting approximately 1 in 3500 individuals. Patients with the disorder can develop carcinoid tumors, medullary thyroid carcinoma, pheochromocytoma and tumor of the hypothalamus. The association of NF1 with Primary Hyperparathyroidism (HPP) is very rare. We report a 56-year-old woman with NF1 who was referred to our service because of nephrolithiasis. Physical examination revealed the characteristic signs of NF1, and her laboratory calcium profile was compatible with HPP. The patient was referred for parathyroidectomy, but during the surgical work-up she underwent spontaneous remission of her HPP. This case is significant not only for the rarity of this presentation in NF1 patients, but also because of the spontaneous remission of HPP.

Primary malignant epithelioid hemangioendothelioma (MEH) of the thyroid is a rare neoplasia with only a few cases reported in the literature. We report a 75 year old man, who presented with a substernal goiter and compressive symptoms. Ultrasonographic evaluation revealed a hypoechogenic nodule in the left lobe, measuring 4.1 cm in maximum diameter, and associated gross calcifications. Fine needle aspiration yielded hemorrhagic material. A left thyroid lobectomy and isthmusectomy was performed. The surgical specimen contained a malignant epithelioid hemangioendothelioma measuring 6 x 4 x 3 cm that had infiltrated about 50% of the thyroidal parenchyma, and surrounded a necrotic nodule. Immunohistochemistry results corroborated the histopathological findings; staining was positive for AE1/AE3, CD31, CD34, factor VIII-related antigen, and Ki-67 expression. Because of the patient’s comorbidities, surgical complementation was not undertaken and he has been undergoing conservative treatment.

Background: Initially described by Gorlin et al. in 1962, the calcifying cystic odontogenic tumor (CCOT) may be associated with unerupted teeth, ameloblastomas, adenomatoid odontogenic tumors, and, in many cases, with odontomas. It is rare in patients in the first decade of life, particularly involving deciduous teeth. Surgery is the treatment of choice, with low recurrence rates. Case report: We present a clinical case of CCOT associated with odontoma and a missing deciduous tooth in a 3-year-old female patient. The lesion was removed under general anesthesia. The patient has been followed up for 1 year, and no recurrence was found. This appears to be the first report in such a young age

Several practical obstacles in data handling and evaluation complicate the use of quantitative localized magnetic resonance spectroscopy (qMRS) in clinical routine MR examinations. To overcome these obstacles, a clinically feasible MR pulse sequence protocol based on standard available MR pulse sequences for qMRS has been implemented along with newly added functionalities to the free software package jMRUI-v5.0 to make qMRS attractive for clinical routine. This enables (a) easy and fast DICOM data transfer from the MR console and the qMRS-computer, (b) visualization of combined MR spectroscopy and imaging, (c) creation and network transfer of spectroscopy reports in DICOM format, (d) integration of advanced water reference models for absolute quantification, and (e) setup of databases containing normal metabolite concentrations of healthy subjects. To demonstrate the work-flow of qMRS using these implementations, databases for normal metabolite concentration in different regions of brain tissue were created using spectroscopic data acquired in 55 normal subjects (age range 6-61 years) using 1.5T and 3T MR systems, and illustrated in one clinical case of typical brain tumor (primitive neuroectodermal tumor). The MR pulse sequence protocol and newly implemented software functionalities facilitate the incorporation of qMRS and reference to normal value metabolite concentration data in daily clinical routine.

Problem: Medical and veterinary students memorize facts but then have difficulty applying those facts in clinical problem solving. Cognitive engineering research suggests that the inability of medical and veterinary students to infer concepts from facts may be due in part to specific features of how information is represented and organized in educational materials. First, physical separation of pieces of information may increase the cognitive load on the student. Second, information that is necessary but not explicitly stated may also contribute to the student’s cognitive load. Finally, the types of representations – textual or graphical – may also support or hinder the student’s learning process. This may explain why students have difficulty applying biomedical facts in clinical problem solving. Purpose: To test the hypothesis that three specific aspects of expository text – the patial distance between the facts needed to infer a rule, the explicitness of information, and the format of representation – affected the ability of students to solve clinical problems. Setting: The study was conducted in the parasitology laboratory of a college of veterinary medicine in Texas. Sample: The study subjects were a convenience sample consisting of 132 second-year veterinary students who matriculated in 2007. The age of this class upon admission ranged from 20-52, and the gender makeup of this class consisted of approximately 75% females and 25% males. Results: No statistically significant difference in student ability to solve clinical problems was found when relevant facts were placed in proximity, nor when an explicit rule was stated. Further, no statistically significant difference in student ability to solve clinical problems was found when students were given different representations of material, including tables and concept maps. Findings: The findings from this study indicate that the three properties investigated – proximity, explicitness, and representation – had no statistically significant effect on student learning as it relates to clinical problem-solving ability. However, ad hoc observations as well as findings from other researchers suggest that the subjects were probably using rote learning techniques such as memorization, and therefore were not attempting to infer relationships from the factual material in the interventions, unless they were specifically prompted to look for patterns. A serendipitous finding unrelated to the study hypothesis was that those subjects who correctly answered questions regarding functional (non-morphologic) properties, such as mode of transmission and intermediate host, at the family taxonomic level were significantly more likely to correctly answer clinical case scenarios than were subjects who did not correctly answer questions regarding functional properties. These findings suggest a strong relationship (p < .001) between well-organized knowledge of taxonomic functional properties and clinical problem solving ability. Recommendations: Further study should be undertaken investigating the relationship between knowledge of functional taxonomic properties and clinical problem solving ability. In addition, the effect of prompting students to look for patterns in instructional material, followed by the effect of factors that affect cognitive load such as proximity, explicitness, and representation, should be explored.

Introdution: Haemochromatosis-type IV, the ferroportin disease, is characterized by an autosomal-dominant transmission and early iron accumulation in macrophages. It is caused by mutations in the transmembrane iron exporter protein ferroportin1 (SLC40A1 gene). In form A (classic), ferroportin loss of function mutants are unable to export iron from cells leading to cellular iron accumulation with decreased availability of iron for serum transferrin (TS). We present a Portuguese rare clinical case of HH-IV. Materials and Methods: A 41-year-old woman with hyperferritinemia and normal TS. Causes of hyperferritinemia (inflammation, chronic alcohol consumption, metabolic syndrome, cell necrosis, non-alcoholic fatty liver disease and aceruloplasminemia) were assessed. Liver iron, evaluated by magnetic resonance imaging (MRI) was carried out. Screening for mutation in HFE and SCL40A1 genes were performed by Sanger sequencing. Baseline: Ferritin:708ng/ml; TS: 27%; MRI:85µmol/g; Hb:13,6g/dl. Therapy: weekly 450ml Therapeutic Phlebotomies (TP) until ferritin≤50ng/ml. Results: Hyperferritinemia comorbidities and common genetic mutations for haemochromatosis were negative. However, sequencing of the patient SLC40A1 gene has revealed the presence in heterozygosity of the variant c.238G>A; p.Gly80Ser. Due to low tolerance to TP, we adopted smaller phlebotomies every three weeks. Conclusion: This patient has a rare autosomal-dominant Ferroportin disease due to a mutated ferroportin which is predicted to be defective in iron cellular export. In agreement, she presents hyperferritinemia, with normal TS and liver iron overload. The genotype/phenotype association allowed to diagnosis this rare FD case. Although a mild form A, we decided to start TP. Her father also has been treated for iron overload.

The prevalence of diabetic polyneuropathy in Spain is 22% increasing with age, standing at less than 5% in patients between 15 and 19 years and reaching 29.8% in those aged 70 to 74 years age. Infection is an important complication in Diabetic Foot, frequently associated with minor amputation and even lower extremity amputation. The study presents a clinical case of a 68-year-old man who consulted for a diabetic foot ulcer in the metatarseal area of the right foot, diagnosed two years ago and without healing success. An exploration protocol of the diabetic food was made. Afterwards, a surgical debridement was done and a cure procedure with pure hyaluronic acid, a bandage and foot unloading was followed. After 69 days of treatment, a complete ulcer healing was achieved. After the injure healing, a biomechanical exploration was made and a plantar support was produced to avoid the reappearance of the injury because of local hyperpressure.

The gallstone ileus is a rare complication of cholelithiasis and it represents the 1-4% of small intestinal mechanical obstruction. Gallstone is generally wedged in the terminal ileum, even if unusual locations have been described. The literature reports a very high morbidity and mortality, often because misdiagnosis or delayed diagnosis. There is no unique opinion in literature about the choice between one-stage and two-stage surgery. We report a clinical case that summarizes the diagnostic and therapeutic difficulties of gallstone ileus.

The authors describe a clinical case of a patient with neuroendocrine carcinoma of the lung diagnosed after the onset of an intestinal obstruction from an ileal metastasis. A review of literature reveals that the incidence of symptomatic gastro-intestinal metastases from lung cancer has been estimated to be about 2-3% and is exceedingly rare that the intestinal symptoms may be the initial presentation of cancer of the lung. The authors emphasize the difficulty of preoperative diagnosis of gastro-intestinal metastases which is made, almost always, too late because of the lack of specific symptoms. In our case, on account of the computed tomography, we leaned towards the diagnosis of lymphoma because of the double mediastinal and abdominal localization. Furthermore, this diagnosis was supported by the fact that the pulmonary lesion did not have clear radiological features of a lung cancer. The prognosis is poor because once intestinal metastases occur, other metastatic sites, which would make surgery only a palliative measure, are already present. The review of the literature shows that the average survival rate of these patients is 136 days. In our case the patient survived 277 days.

This study describes the treatment of obese individuals who rated high on emotional eating using four case studies that involved 22 sessions of either cognitive behavioral therapy (CBT) or dialectical behavioral therapy (DBT). Outcomes measures relating to weight, body mass index, emotional eating, depression, anxiety, and stress were all assessed with each participant prior to each baseline (three weekly sessions), during treatment and posttherapy. At the 8-week follow-up, the two cases that had received DBT had lost 10.1% and 7.6% of their initial body weight, whereas the two cases that had received CBT had lost 0.7% and 0.6% of their initial body weight. The two DBT cases also exhibited reductions in emotional distress, frequency of emotional eating or quantity of food eating in response to emotions, whereas the two CBT cases showed no overall reductions in these areas. Important processes from all four cases are described as are the implications to clinicians for developing more effective interventions for obese clients who engage in emotional eating.

Background: Greater research utilisation in cancer nursing practice is needed, in order to provide well-informed and effective nursing care to people affected by cancer. This paper aims to report on the implementation of evidence-based practice in a tertiary cancer centre. Methods: Using a case report design, this paper reports on the use of the Collaborative Model for Evidence Based Practice (CMEBP) in an Australian tertiary cancer centre. The clinical case is the uptake of routine application of chlorhexidine-impregnated sponge dressings for preventing centrally inserted catheter-related bloodstream infections. In this case report, a number of processes that resulted in a service-wide practice change are described. Results: This model was considered a feasible method for successful research utilisation. In this case report, chlorhexidine-impregnated sponge dressings were proposed and implemented in the tertiary cancer centre with an aim of reducing the incidence of centrally inserted catheter-related bloodstream infections and potentially improving patient health outcomes. Conclusion: The CMEBP is feasible and effective for implementing clinical evidence into cancer nursing practice. Cancer nurses and health administrators need to ensure a supportive infrastructure and environment for clinical inquiry and research utilisation exists, in order to enable successful implementation of evidence-based practice in their cancer centres.

This editorial depicts the current challenges in palliative care provision for patients with a haematological malignancy and the contribution of cancer nurses. There have been significant advancements in the care of patients with a hematological malignancy over the past three or more decades1. Despite this, there still exists a significant mortality risk in curative treatment and many patients with a hematological malignancy will die from their disease1. A growing body of research indicates patients with a hematological malignancy do not receive best practice palliative and end-of-life care2. Shortfalls in care include poor referral patterns to specialist palliative care services, lack of honest discussions regarding death and dying, inadequate spiritual care for patients and families, patients frequently dying in the acute care setting and high levels of patient and family distress2. There have been a number of efforts in the United Kingdom, United States of America, Sweden, and Australia demonstrating palliative and hematology care can co-exist, exemplified through clinical case studies and innovative models of care2. However, deficits in the provision of palliative care for patients with a hematological malignancy persist as evident in the international literature2. Addressing this issue requires research exploring new aspects of a complex scenario; here we suggest priority areas of research...

Purpose To report an unusual case of a late-stage reactivation of immune stromal keratitis associated with herpes zoster ophthalmicus (HZO), occurring without any apparent predisposing factors, more than 4 years after an acute zoster dermatomal rash. Significant corneal hypoesthesia and a central band keratopathy developed within 6 months of the late-stage reactivation. The clinical case management, issues associated with management, and management options are discussed, including the use of standardized, regulatory approved, antibacterial medical honey. Case Report An 83-year-old woman presented for routine review with a reactivation of right anterior stromal keratitis and mild anterior uveitis, occurring more than 4 years after an acute HZO dermatomal rash and an associated initial episode of anterior stromal keratitis. Corneal sensation became markedly impaired, and over the subsequent 6 months, a right central band keratopathy developed despite oral antiviral and topical steroid therapy. Visual acuity with pinhole was reduced to 20/100 in the affected eye and moderate irritation and epiphora were experienced. The patient declined the surgical intervention options of chelation, lamellar keratectomy, and phototherapeutic keratectomy to treat the band keratopathy. Longer-term management has involved preservative-free artificial tears, eyelid hygiene, standardized antibacterial medical honey, topical nonpreserved steroid, and UV-protective wraparound sunglasses. The clinical condition has improved over 14 months with this ocular surface management regimen, and visual acuity of 20/30 is currently achieved in a comfortable eye. Conclusions The chronic and recurrent nature of HZO can be associated with significant corneal morbidity, even many years after the initial zoster episode. Long-term review and management of patients with a history of herpes zoster stromal keratitis are indicated following the initial corneal involvement. Standardized antibacterial medical honey can be considered in the management of the chronic ocular surface disease associated with HZO and warrants further evaluation in clinical trials.
