Chancroid is a sexually transmitted disease characterized by painful ulcers with a soft margin, necrotic base and purulent exudate. Previously, only sporadic, imported cases have been reported in Denmark. The bacterium is difficult to culture and novel polymerase chain reaction (PCR)-based methods for direct demonstration of bacterial DNA have facilitated rapid verification of the clinical diagnosis. We report two cases which demonstrate import and subsequent local transmission in Denmark. In both cases, the clinical diagnosis was rapidly verified by a combined PCR testing for multiple causes of venereal ulcers.

Aneurysmal Bone Cysts of the Spine: Two Case Reports

Ozdemir, Seymen; Ozden, Ferhat; Kacira, Ozlem Kitiki; Kacira, Tibet

2014-01-01

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically. Most cases have uncommon pain symptoms, but rarely, if fractures occur, neurological findings can be seen and the surgical treatment, if needed, could be difficult. We will discuss our evaluations to two cases that we experienced in our clinic in this report. PMID:25620988

Introduction: In outbreak settings, more than one virus may be infecting the given population. In twin or triple outbreak of measles, German measles (rubella), and varicella in highly immunized hilly areas, maximal number of the case patients in all the hilly villages belonged to the older age group. It suggested an obvious shift to the higher age group, warranting second dose opportunity in such case scenario. The clinical presentations of viral diseases are too similar to differentiate. The aim is to clearly categorize the case patients of modified measles, rubella, and atypical measles in outbreak settings. Results: Four outbreaks are listed. In the first one, sixty case patients were identified from 1026 people in 5 villages. Of these, 41 were diagnosed by clinically, 8 were laboratory confirmed as measles and 11 were epidemiologically linked German measles case patients. Seventy percent of the cases were vaccinated for measles. In second case, we identified 29/35 measles and 6/35 were confirmed as epidemiologically linked unvaccinated chickenpox case patients. In third one, we identified 116 cases in eight villages (112/116 clinically and 04/116 laboratory confirmed). Majority of cases were immunized against measles, but only minor cases for rubella. In fourth case, we identified 505 case patients from mixed outbreaks of varicella, measles and rubella (30/505 clinically, 467/505 epidemiologically linked and 8/505 laboratory confirmed case patients from a study population of 3280). In all the four outbreaks, prima facie, the clinical presentations of both rubella and modified measles were difficult to differentiate. Discussion: On the basis of outbreak investigation and analytical inference, it has been observed that the symtomatology of modified measles and laboratory confirmed rubella case patients/epidemiologically linked cases are so similar placed that many a time, it becomes much difficult to line list the cases in one section of modified measles or rubella or atypical cases. Conclusion: Similarities of morphological symptoms between modified measles and rubella is the point of challenge and it causes debate between pediatrician and field epidemiologist to differentiate and classify them.

[Perioperative onset of sarcoidosis : Rare differential diagnosis of a difficult airway].

PubMed

Jansen, G; Nowak, A

2018-05-01

Sarcoidosis is a rare multisystemic chronic inflammatory condition. Typically, there is a big discrepancy between the patient's subjectively perceived symptoms and the presence of clinical signs. Due to the high number of potential sites of onset (e. g. larynx, lungs, heart, liver, kidneys) the affected organs may show functional restrictions that are relevant for decisions related to anesthesia. Therefore, an anesthetists working in a clinical setting should be familiar with the special needs of this patient collective. This article describes the onset of sarcoidosis in a case of an unexpected difficult airway.

CT of trauma to the abnormal kidney

Rhyner, P.; Federle, M.P.; Jeffrey, R.B.

Traumatic injuries to already abnormal kidneys are difficult to assess by excretory urography and clinical evaluation. Bleeding and urinary extravasation may accompany minor trauma; conversely, underlying tumors, perirenal hemorrhage, and extravasation may be missed on urography. Computed tomography (CT) was performed in eight cases including three neoplasms, one adult polycystic disease, one simple renal cyst, two hydronephrotic kidneys, and one horseshoe kidney. CT provided specific and clinically useful information in each case that was not apparent on excretory urography.

Neighborhood graph and learning discriminative distance functions for clinical decision support.

PubMed

Tsymbal, Alexey; Zhou, Shaohua Kevin; Huber, Martin

2009-01-01

There are two essential reasons for the slow progress in the acceptance of clinical case retrieval and similarity search-based decision support systems; the especial complexity of clinical data making it difficult to define a meaningful and effective distance function on them and the lack of transparency and explanation ability in many existing clinical case retrieval decision support systems. In this paper, we try to address these two problems by introducing a novel technique for visualizing inter-patient similarity based on a node-link representation with neighborhood graphs and by considering two techniques for learning discriminative distance function that help to combine the power of strong "black box" learners with the transparency of case retrieval and nearest neighbor classification.

Scombroid syndrome: it seems to be fish allergy but... it isn't.

Scombroid poisoning is a frequent cause of admission in emergency department. In everyday clinical practice, it can be difficult to discriminate between scombroid syndrome and fish allergy. The aim of this review is to provide the clinician some instruments to make a correct differential diagnosis. In the last few years, a better characterization of scombroid syndrome occurred, in particular regarding its possible severe presentations. Two cases of Kounis syndrome secondary to scombroid syndrome have been described and in these cases a differential diagnosis in patients with this clinical presentation can be even more difficult. Finally, in term of diagnosis, the useful role of serum tryptase was recently consolidated. Scombroid syndrome is a histamine-induced reaction because of the ingestion of histamine-contaminated fish, whereas fish allergy is an IgE-mediated reaction. Clinical presentation can be similar and for this reason scombroid syndrome is often misdiagnosed. The differences lie in pathogenic mechanisms, possible outcome, therapy, and prevention measures. Moreover, some laboratory tests are helpful to discriminate between the two diseases.

Acute cholecystitis: comparing clinical outcomes with TG13 severity and intended laparoscopic versus open cholecystectomy in difficult operative cases.

The revised Tokyo Guidelines include criteria for determining the severity of acute cholecystitis with treatment algorithms based on severity. The aim of this study was to investigate the relationship of the revised Tokyo Guidelines severity grade to clinical outcomes of cholecystectomy for acute cholecystitis. We identified 66 patients with acute cholecystitis from a prior study of difficult cholecystectomy cases. We examined the relationship between severity grade and multiple variables related to perioperative and postoperative outcomes. A more severe revised Tokyo Guidelines grade was associated with a higher number of complications (p = 0.03) and a higher severity of complications (p = 0.01). Severity grade did not predict operative time, estimated blood loss, intensive care unit admission or length of stay. Compared to planned open cholecystectomy, intended laparoscopic cholecystectomy was associated with significantly fewer total and Clavien-Dindo grade 3 complications, fewer intensive care unit admissions, and shorter length of stay (p values range from 0.03 to < 0.0001). In technically difficult operations for acute cholecystitis, the revised Tokyo guidelines severity grade correlates with the number and severity of complications. However, intended performance of laparoscopic cholecystectomy rather than open cholecystectomy in difficult operations predicts broader beneficial outcomes than severity grade.

Nasal glial heterotopia or congenital hemangioma? A case report.

2017-10-01

Nasal glial heterotopia (NGH) is a rare benign tumor of the median line. We describe the case of a child presenting a lateral nasal mass. The characteristics of the prenatal ultrasound and the postnatal clinical examination argued in favor of a congenital hemangioma (CH). The MRI performed at 6 weeks of life suggested glial heterotopia. This diagnosis was confirmed by the pathological analysis. Congenital hemangiomas and nasal glial heterotopies have similar clinical presentations. Prenatal ultrasound diagnosis between NGH and CH is difficult. Fetal MRI is not yet highly specific for these two lesions, but it can eliminate an intracerebral connection in cases of NGH. Postnatal exams are more specific. Flow on the Doppler exam is rapid for CH and slow for NGH. On MRI, these two lesions appear as a hypersignal on T2-weighted sequences, but less intense for NGH than for CH. Distinguishing between NGH and CH can be difficult. This does not have a direct incidence on treatment because it is surgical in both cases. Copyright © 2017 Elsevier Masson SAS.

ABSTRACT Pulmonary blastoma (PB) is a rare form of lung tumour and is accountable for 0.25–0.5% of primary pulmonary malignancies. Initially pulmonary blastoma was divided into three subtypes: biphasic pulmonary blastoma (BPB) consisting of an epithelial and mesenchymal component, well differentiated fetal adenocarcinoma (WDFA) built of well differentiated epithelium and a mesenchymal component and malignant pleuropulmonary blastoma (PPB). Prognosis in this type of cancer is really poor. We present a current review of literature and a clinical case report. Treatment of PB is very difficult. Data and recommendations about the treatment of pulmonary blastoma are still available therefore we should use only observations and clinical case reports. PMID:28008207

Secondary hypertension accounts for 10-15% of all cases of hypertension, and early diagnosis with identification of its etiology can be challenging. In this scenario, therapeutic management of affected patients may be difficult. Hypercortisolism is one of the possible causes of secondary hypertension, but its low prevalence and atypical clinical symptoms can lead to a delayed diagnosis. The complex clinical presentation and potential complications need a close collaboration among different clinicians in order to plan optimal or new treatment protocols.

Autism spectrum disorder (ASD) is estimated to affect one in 68 children. Given the increase in both prevalence and awareness of ASD, it is critical to provide accurate and timely diagnosis. However, ASD often co-occurs with other disorders, making diagnosis difficult. The objective of the current case study was to provide two examples of differential diagnosis in ASD and post-traumatic stress disorder (PTSD) observed in an autism clinic. In both cases, the goal was to decide whether each child should be given a diagnosis of ASD, PTSD, or both. PMID:29642485

Fully covered self-expandable metal stents (FCSEMS) have been used for the treatment of benign esophageal conditions such as perforation, leaks, and strictures [1]; high clinical success is reported [2]. Different anchoring methods have been described (clips, suturing devices, over-the-scope clips and Shim technique [2]), because of high migration rates (4-36%) [3,4]. However, not all cases are candidates, mostly in "difficult" cases where enteral feeding is needed [5]. We report the use of the nasojejunal-stent technique (NJST) to prevent migration of FCSEMS in three difficult cases. This article is protected by copyright. All rights reserved.

Berardinelli–Seip congenital lipodystrophy (BSCL) syndrome is a rare autosomal-recessive disease characterised by lipoatrophy and associated with deregulations of glycidic and lipid metabolism. We report three BSCL cases with its typical clinical picture and complications. Clinically, they all show marked atrophy of adipose tissue, acromegaly, acanthosis nigricans and tall stature. Two cases present attention deficit hyperactivity and developmental learning disorders; another patient has hypertrophic myocardiopathy and polycystic ovary syndrome. In all the cases AGPAT2 was the identified mutation. All the cases present hypertriglyceridemia. One case has developed hyperinsulinism controlled with metformin and another case already has type 2 diabetes with a difficult clinical control. There is no curative treatment and the current treatment options are based only on symptomatic control of the complications. Recently, published studies showed that leptin-replacement therapy appears a promising tool in the metabolic correction of BSCL complications, highlighting the importance of further investigations in BSCL treatment.

Hereditary neuropathy with liability to pressure palsy: two cases of difficult diagnosis.

Beydoun, Said R; Cho, Justin

2013-09-01

Hereditary neuropathy with liability to pressure palsies (HNPP) is an inherited autosomal dominant disorder that causes a polyneuropathy with predisposition for involvement at sites of compression and is often underdiagnosed or misdiagnosed due to its heterogeneity in clinical and electrophysiological presentation. We report 2 cases of HNPP, which were initially diagnosed and treated as either an acquired demyelinating disorder or alternative inherited demyelinating disorder. Thorough evaluation of repeat electrodiagnostic studies and genetic testing confirmed the diagnosis of HNPP in both cases. One case showed the classic peripheral myelin protein 22 (PMP22) deletion and the other case showed a previously reported single base pair deletion at Leu145 causing a frameshift mutation at the PMP22 gene. These cases underscore the difficulty of diagnosing HNPP, because of the variations in clinical and electrophysiological findings and reinforce the importance of a combination high index of clinical suspicion, electrodiagnostic testing, and genetic testing to make the diagnosis.

Tinea incognita is a dermatophytic infection that is difficult to diagnose, usually modified by inappropriate topical or systemic corticosteroid therapy. We report an extensive case of tinea incognita caused by the zoophilic dermatophyte Trichophyton mentagrophytes (var. granulosa) in a 49-year-old female patient with CREST (Calcinosis; Raynaud phenomenon; Esophageal involvement; Sclerodactyly; Teleangiectasia) syndrome. Immunocompromised patients, as well as patients with keratinization disorders, seem to be especially susceptible to dermatophytic infections with atypical clinical presentation that is sometimes bizarre and difficult to recognize. Therefore, close monitoring and mycological skin examination is recommended in order to avoid misdiagnosis and to give the patient the best chance of recovery.

1997-11-01

We carried out a preliminary clinical validation of 3D spiral CT virtual endoscopic reconstructions of the tracheobronchial tree, by comparing virtual bronchoscopic images with actual endoscopic findings. Twenty-two patients with tracheobronchial disease suspected at preliminary clinical, cytopathological and plain chest film findings were submitted to spiral CT of the chest and bronchoscopy. CT was repeated after endobronchial therapy in 2 cases. Virtual endoscopic shaded-surface-display views of the tracheobronchial tree were reconstructed from reformatted CT data with an Advantage Navigator software. Virtual bronchoscopic images were preliminarily evaluated with a semi-quantitative quality score (excellent/good/fair/poor). The depiction of consecutive airway branches was then considered. Virtual bronchoscopies were finally submitted to double-blind comparison with actual endoscopies. Virtual image quality was considered excellent in 8 cases, good in 14 and fair in 2. Virtual exploration was stopped at the lobar bronchi in one case only; the origin of segmental bronchi was depicted in 23 cases and that of some subsegmental branches in 2 cases. Agreement between actual and virtual bronchoscopic findings was good in all cases but 3 where it was nevertheless considered satisfactory. The yield of clinically useful information differed in 8/24 cases: virtual reconstructions provided more information than bronchoscopy in 5 cases and vice versa in 3. Virtual reconstructions are limited in that the procedure is long and difficult and needing a strictly standardized threshold value not to alter virtual findings. Moreover, the reconstructed surface lacks transparency, there is the partial volume effect and the branches < or = 4 pixels phi and/or meandering ones are difficult to explore. Our preliminary data are encouraging. Segmental bronchi were depicted in nearly all cases, except for the branches involved by disease. Obstructing lesions could be bypassed in some cases, making an indication for endoscopic laser therapy. Future didactic perspectives and applications to minimally invasive or virtual reality-assisted therapy seem promising, even though actual clinical applications require further studies.

Atypical angioimmunoblastic T-cell lymphomas masquerading as systemic polyclonal B-immunoblastic proliferation.

Papadi, Bhavesh; Polski, Jacek M; Clarkson, David R; Liu-Dumlao, Theresa O

2012-09-01

Angioimmunoblastic T cell lymphoma (AITL) is a relatively rare peripheral T cell lymphoma derived from follicular T helper cells. AITL has a varied presentation, both clinically and morphologically. AITL can pose a diagnostic challenge as it may be difficult to identify and characterize the neoplastic cells among the polymorphous infiltrates composed of polyclonal B immunoblasts and plasma cells. In AITL, the reactive B cell and plasma cell proliferation is secondary to dysregulated secretion of cytokines such as interleukin-6 by the neoplastic follicular T helper cells. SPBIP is a condition of unknown etiopathogenesis characterized by systemic involvement by polyclonal B immunoblasts and plasma cells. We report two cases of AITL, which are presented with atypical findings making it difficult to diagnose. The cases had features similar to SPBIP. Our cases highlight the importance of screening cases of polyclonal plasmacytosis and SPBIP like cases for underlying AITL.

Cardiac tumors are exceptional cardiac conditions, since they have a minimal occurrence, according to statistics. The cardiac myxoma cases are the most dominant for the representative examples for these clinical situations. Those tumors being benign, the patients enjoy a reasonable life expectancy provided they receive an early diagnosis. In the absence of potential complications, the symptoms can vary very much and they may often be non-specific, a fact which makes it more difficult to establish a proper diagnosis and to quickly tailor the optimal therapeutic solutions. Surgery is, in the most cases, a comfortable solution, allowing the cases to be permanently healed. Nowadays, cardiac surgery provides all the needed facilities to diagnose cases at an early stage, when diagnosis is quick and accurate. This paper illustrates, by the means of two suggestive cases, how difficult it is to establish a quick positive diagnosis, which is vital for healing this condition with an evolutionary risk frequently worsen by major complications.

Endo-perio lesions primarily occur by way of the intimate anatomic and vascular connections between the pulp and the periodontium. Endodontic-periodontal combined lesion is a clinical dilemma because making a differential diagnosis and deciding a prognosis are difficult. An untreated primary endodontic lesion may become secondarily involved with periodontal breakdown, which clinically present unusual signs and symptoms. This may delay the diagnosis and hence the correct treatment.

Increased clinician workload is associated with medical errors and patient harm. The Quality and Workload Assessment Tool (QWAT) measures anticipated (pre-case) and perceived (post-case) clinical workload during actual surgical procedures using ratings of individual and team case difficulty from every operating room (OR) team member. The purpose of this study was to examine the QWAT ratings of OR clinicians who were not present in the OR but who read vignettes compiled from actual case documentation to assess interrater reliability and agreement with ratings made by clinicians involved in the actual cases. Thirty-six OR clinicians (13 anesthesia providers, 11 surgeons, and 12 nurses) used the QWAT to rate 6 cases varying from easy to moderately difficult based on actual ratings made by clinicians involved with the cases. Cases were presented and rated in random order. Before rating anticipated individual and team difficulty, the raters read prepared clinical vignettes containing case synopses and much of the same written case information that was available to the actual clinicians before the onset of each case. Then, before rating perceived individual and team difficulty, they read part 2 of the vignette consisting of detailed role-specific intraoperative data regarding the anesthetic and surgical course, unusual events, and other relevant contextual factors. Surgeons had higher interrater reliability on the QWAT than did OR nurses or anesthesia providers. For the anticipated individual and team workload ratings, there were no statistically significant differences between the actual ratings and the ratings obtained from the vignettes. There were differences for the 3 provider types in perceived individual workload for the median difficulty cases and in the perceived team workload for the median and more difficult cases. The case difficulty items on the QWAT seem to be sufficiently reliable and valid to be used in other studies of anticipated and perceived clinical workload of surgeons. Perhaps because of the limitations of the clinical documentation shown to anesthesia providers and OR nurses in the current vignette study, more evidence needs to be gathered to demonstrate the criterion-related validity of the QWAT difficulty items for assessing the workload of nonsurgeon OR clinicians.

2017-07-18

The number of older people with polypharmacy (more than six drugs taken simultaneously) is increasing. The greatest proportion consists of guideline drugs, analgesics and psychopharmaceuticals because in many cases of geriatric multimorbidity several underlying main diseases are present which must be treated according to the guidelines. Polypharmacy is a complex and difficult situation for all treating physicians because substantial side effects and intoxication can be induced but it can also be very difficult to recognize which drug was at fault and how a reduction can be safely made. This article describes the exemplary case of a 77-year-old patient with drug-induced delirium and demonstrates the procedure followed. The question of rapid assistance by the utilization of medication data bases is described and the importance of clinical pharmacists is demonstrated. In the future working with medication data bases will possibly become increasingly more important for physicians and hopefully simpler. The case presented here also shows that the effective and justified reduction of drugs can show a very good effect and is possible.

Misleading Gastrointestinal Symptoms: The Ongoing Story of Chronic Lead Intoxication.

2016-10-01

Inorganic lead intoxication has emerged as an important and challenging clinical problem owing to increased awareness of lead and enhanced surveillance of exposed individuals. However, recognition may not be very difficult when there is an obvious history of exposure. Our interest began a few years ago when we could trace an outbreak, following a patient who was admitted with colickly abdominal pain, convulsions, and coma. After that, 16 more cases were identified and characterized. All patients recovered completely after adequate chelation therapy. Although the clinical picture of lead intoxication is pleomorphic, the increased awareness of gastroenterologists in this subject may possibly bring chronically complaining difficult patients to an earlier, unexpected, and fairly treatable disease.

Syncope: causes, clinical evaluation, and current therapy.

Syncope is a common clinical problem comprising the sudden loss of both consciousness and postural tone, with a subsequent spontaneous and relatively prompt recovery. Often it is difficult to differentiate a true syncopal spell from other conditions, such as seizure disorders, or from some simple accidents. Even more difficult is the identification of the cause of syncopal episodes. Nonetheless, establishing a definitive diagnosis ia an important task given the high risk of recurrent symptoms. Careful use of noninvasive and invasive cardiovascular studies (including electrophysiologic testing and tilt-table testing) along with selected hematologic, biochemical, and neurologic studies provides, in the majority of cases, the most effective strategy for obtaining a specific diagnosis and for directing therapy.

Crisis management during anaesthesia: difficult intubation.

Paix, A D; Williamson, J A; Runciman, W B

Anaesthetists may experience difficulty with intubation unexpectedly which may be associated with difficulty in ventilating the patient. If not well managed, there may be serious consequences for the patient. A simple structured approach to this problem was developed to assist the anaesthetist in this difficult situation. To examine the role of a specific sub-algorithm for the management of difficult intubation. The potential performance of a structured approach developed by review of the literature and analysis of each of the relevant incidents among the first 4000 reported to the Australian Incident Monitoring Study (AIMS) was compared with the actual management as reported by the anaesthetists involved. There were 147 reports of difficult intubation capable of analysis among the first 4000 incidents reported to AIMS. The difficulty was unexpected in 52% of cases; major physiological changes occurred in 37% of these cases. Saturation fell below 90% in 22% of cases, oesophageal intubation was reported in 19%, and an emergency transtracheal airway was required in 4% of cases. Obesity and limited neck mobility and mouth opening were the most common anatomical contributing factors. The data confirm previously reported failures to predict difficult intubation with existing preoperative clinical tests and suggest an ongoing need to teach a pre-learned strategy to deal with difficult intubation and any associated problem with ventilation. An easy-to-follow structured approach to these problems is outlined. It is recommended that skilled assistance be obtained (preferably another anaesthetist) when difficulty is expected or the patient's cardiorespiratory reserve is low. Patients should be assessed postoperatively to exclude any sequelae and to inform them of the difficulties encountered. These should be clearly documented and appropriate steps taken to warn future anaesthetists.

This clinical report presents a new method for retrieving separated instruments from the root canal with minimally invasive procedures. The presence of separated instrument in root canal may interfere in the endodontic treatment prognosis. There are several recommended methods to retrieve separated instruments, but some are difficult in clinically practice. This study describes two cases of separated instrument removal from the root canal using a stainless-steel prepared needle associated with a K-file. Case 1 presented a fractured gutta-percha condenser within the mandibular second premolar, it was separated during incorrect intracanal medication calcium hydroxide placement. Case 2 had a fractured sewing needle within the upper central incisor that the patient used to remove food debris from the root canal. After cervical preparation, the fractured instruments were fitted inside a prepared needle and then an endodontic instrument (#25 K-file) was adapted with clockwise turning motion between the needle inner wall and the fragment. The endodontic or atypical nonendodontic separated instrument may be easily pull on of the root canal using a single and low cost device. The methods for retrieving separated instruments from root canal are difficult and destructive procedures. The present case describes a simple method to solve this problem.

It may be clinically difficult to differentiate early-stage melanoma from benign tumors, specially pigmented seborrheic keratosis. Dermoscopy can help; however, the findings are not always conclusive. Therefore, histopathology may be necessary for a correct diagnosis. We describe a melanocytic lesion with dubious clinic and dermoscopic findings. An incisional biopsy of a suspicious area, guided by dermoscopy, was performed to clarify the findings. PMID:23539018

The objective structured clinical examination (OSCE) can be used to evaluate the Accreditation Council for Graduate Medical Education Core Competencies of Professionalism and Interpersonal and Communication Skills. The aim of this study was to describe general surgery resident performance on a "difficult conversation" OSCE. In this prospective study, junior and senior residents participated in a 2-station OSCE. Junior stations involved discussing operative risks and benefits and breaking bad news. Senior stations involved discussing goals of care and discussing transition to comfort measures only status. Residents completed post-OSCE checklist and Likert-based self-evaluations of experience, comfort, and confidence. Trained standardized patients (SPs) evaluated residents using communication skill-based checklists and Likert-based assessments. Pearson correlation coefficients were determined between self-assessment and SP assessment. Mann-Whitney U tests were conducted between junior and senior resident variables, using α = 0.05. There were 27 junior residents (age 28.1 ± 1.9 years [29.6% female]) and 27 senior residents (age 32.1 ± 2.5 years [26.9% female]). The correlation of self-assessment and SP assessment of overall communication skills by junior residents was -0.32 on the risks and benefits case and 0.07 on the breaking bad news case. The correlation of self-assessment and SP assessment of overall communication skills by senior residents was 0.30 on the goals of care case and 0.26 on the comfort measures only case. SP assessments showed that junior residents had higher overall communication skills than senior residents (p = 0.03). Senior residents perceived that having difficult conversations was more level appropriate (p < 0.001), and they were less nervous having difficult conversations (p < 0.01) than junior residents. We found that residents perform difficult conversations well, that subjective and objective skills are correlated, and that skills-based training is needed across all residency levels. This well-received method may be used to observe, document, and provide resident feedback for these important skills. © 2014 Published by Association of Program Directors in Surgery on behalf of Association of Program Directors in Surgery.

2000-07-01

In typical cases, the patient's history and clinical examination make it possible to diagnose ocular myasthenia gravis (OMG). But, in many cases a clear clinical picture is not present and OMG diagnosis is very difficult because gold diagnostic standard tests are not available. The diagnostic tests for OMG are usually unable to display a good sensitivity and specificity simultaneously. In this paper, we studied 86 cases submitted for suspected OMG. The patients were studied clinically and with various other tests used in OMG diagnosis (SFEMG, repetitive nerve stimulation, Ab anti AChR titration, tensilon test). SFEMG showed the highest sensitivity (100%) while Ab anti AChR showed the highest specificity (100%). To our knowledge this is the largest population of suspected OMG studied using most of the diagnostic parameters, reported in the literature.

Rasmussen encephalitis is a rare, devastating condition, typically presenting in childhood. Cases of adult-onset Rasmussen have also been described, but the clinical picture is less defined, rendering final diagnosis difficult. We present a case of adult-onset Rasmussen encephalitis with dual pathology, associated with focal cortical dysplasia and encephalitis. We interpreted the Rasmussen encephalitis to be caused by severe and continuous epileptic activity due to focal cortical dysplasia. The best therapeutic approach for such cases remains unclear.

Pyogenic sacroiliitis is exceptional in very young children. Diagnosis is difficult because clinical examination is misleading. FABER test is rarely helpful in very young children. Inflammatory syndrome is frequent. Bone scintigraphy and MRI are very sensitive for the diagnosis. Joint fluid aspiration and blood cultures are useful to identify the pathogen. Appropriate antibiotic therapy provides rapid regression of symptoms and healing. We report the case of pyogenic sacroiliitis in a 13-month-old child.Clinical, biological, and imaging data of this case were reviewed and reported retrospectively.A 13-month-old girl consulted for decreased weight bearing without fever or trauma. Clinical examination was not helpful. There was an inflammatory syndrome. Bone scintigraphy found a sacroiliitis, confirmed on MRI. Aspiration of the sacroiliac joint was performed. Empiric intravenous biantibiotic therapy was started. Patient rapidly recovered full weight bearing. On the 5th day, clinical examination and biological analysis returned to normal. Intravenous antibiotic therapy was switched for oral. One month later, clinical examination and biological analysis were normal and antibiotic therapy was stopped.Hematogenous osteoarticular infections are common in children but pyogenic sacroiliitis is rare and mainly affects older children. Diagnosis can be difficult because clinical examination is poor. Moreover, limping and decreased weight bearing are very common reasons for consultation. This may delay the diagnosis or refer misdiagnosis. Bone scintigraphy is useful to locate a bone or joint disease responsible for limping. In this observation, bone scintigraphy located the infection at the sacroiliac joint. Given the young age, MRI was performed to confirm the diagnosis. Despite the very young age of the patient, symptoms rapidly disappeared with appropriate antibiotic therapy.We report the case of pyogenic sacroiliitis in a 13-month-old child. It reminds the risk of misdiagnosing pyogenic sacroiliitis in children because it is exceptional and clinical examination is rarely helpful. It also highlights the usefulness of bone scintigraphy and MRI in osteoarticular infections in children.

Even though since the mid-1990s the number of food-borne botulism cases has systematically decreased and it now occurs in Poland relatively rarely, it is still a real epidemiological problem. There are about 30 cases of botulism in Poland a year, which ranks Poland the first among the European Union. In most cases the symptomatology of botulism is typical, however it does not always fully coincide with the one described in medical manuals which emphasise the dramatic clinical course of botulism with its frequent fatal consequences. Diagnosis of botulism may be difficult because of its rare prevalence and a variable clinical course, especially in old patients. Authors of this paper describe two cases of botulism and diagnostic problems associated with it.

Literature suggests that patients who display disruptive behaviours in the consulting room fuel negative emotions in doctors. These emotions, in turn, are said to cause diagnostic errors. Evidence substantiating this claim is however lacking. The purpose of the present experiment was to study the effect of such difficult patients' behaviours on doctors' diagnostic performance. We created six vignettes in which patients were depicted as difficult (displaying distressing behaviours) or neutral. Three clinical cases were deemed to be diagnostically simple and three deemed diagnostically complex. Sixty-three family practice residents were asked to evaluate the vignettes and make the patient's diagnosis quickly and then through deliberate reflection. In addition, amount of time needed to arrive at a diagnosis was measured. Finally, the participants rated the patient's likability. Mean diagnostic accuracy scores (range 0-1) were significantly lower for difficult than for neutral patients (0.54 vs 0.64; p=0.017). Overall diagnostic accuracy was higher for simple than for complex cases. Deliberate reflection upon the case improved initial diagnostic, regardless of case complexity and of patient behaviours (0.60 vs 0.68, p=0.002). Amount of time needed to diagnose the case was similar regardless of the patient's behaviour. Finally, average likability ratings were lower for difficult than for neutral-patient cases. Disruptive behaviours displayed by patients seem to induce doctors to make diagnostic errors. Interestingly, the confrontation with difficult patients does however not cause the doctor to spend less time on such case. Time can therefore not be considered an intermediary between the way the patient is perceived, his or her likability and diagnostic performance. Published by the BMJ Publishing Group Limited.

A confirmed Ebola haemorrhagic fever (EHF) outbreak in Bundibugyo, Uganda, November 2007–February 2008, was caused by a putative new species (Bundibugyo ebolavirus). It included 93 putative cases, 56 laboratory-confirmed cases, and 37 deaths (CFR = 25%). Study objectives are to describe clinical manifestations and case management for 26 hospitalised laboratory-confirmed EHF patients. Clinical findings are congruous with previously reported EHF infections. The most frequently experienced symptoms were non-bloody diarrhoea (81%), severe headache (81%), and asthenia (77%). Seven patients reported or were observed with haemorrhagic symptoms, six of whom died. Ebola care remains difficult due to the resource-poor setting of outbreaks and the infection-control procedures required. However, quality data collection is essential to evaluate case definitions and therapeutic interventions, and needs improvement in future epidemics. Organizations usually involved in EHF case management have a particular responsibility in this respect. PMID:23285243

Carriers of completely balanced chromosomal translocations have all necessary genetic information. Nevertheless, because of the possibility of maldistribution during gametogenesis, they are at increased risk for infertility, miscarriage, stillbirth or having a child with congenital anomalies including mental retardation. As postnatal clinical reports are infrequent, prediction of clinical course for specific unbalanced karyotypes diagnosed during pregnancy remains difficult. Here, we report the 6th case of partial trisomy 6p and partial monosomy 20p due to an unbalanced adjacent-1 segregation of the rare familial translocation t(6;20)(p21;p13). We give a thorough clinical description of the present case, demonstrating broad phenotypic overlap with the 5 previously published cases reviewed here, providing important data on postnatal outcome.

Clinical faculty often struggle to design competency demonstrations that promote quality learning experiences. A nursing program in Oregon combined mental health and community health nursing practica and required well-planned, integrated competency demonstrations. This requirement became the impetus for students to promote the health of clients and learn clinical concepts that are difficult to experience in a typical term. Faculty coached students to make a significant contribution that would last beyond their clinical practica. A case study in competency demonstration design is described, and implications for curriculum development are presented.

In the last years exotic snakebite envenomations are increasingly reported. These cases are difficult to manage because of the limited experience of European physicians in the treatment of bites from such venomous snakes; moreover, specific antivenoms are unevenly stocked and they are difficult to find in case of a medical emergency. A 39-year-old herpetologist was bitten in his right hand by a mexican moccasin (Agkistrodon bilineatus) at the workplace, and presented in the Emergency Department 19 hours later. At admission, clinical evaluation showed local necrosis, swelling involving the entire limb up to the trunk, and severe pain. The specific antidote, not stocked in Italy, was sought abroad; its finding and routeing up to spot delivery required 12 hours. The antivenom, given 32 hours after the bite with no adverse reactions, was only partially effective. The clinical course was characterized by extensive edema with rhabdomyolysis. The necrotic wound at the bite site required after several days surgical debridement, and eventually skin graft. At 3 months follow-up, motor impairment of his right hand fingers with functional disability was still present. The envenomation by Agkistrodon bilineatus has some clinical aspects in common with that by European viper species, although crotalid venom usually causes more severe manifestations. The antivenom supply from a foreign country may delay its administration. A specific legislation aimed to simplify antidotes importing procedures for professional snake handlers may improve antivenoms availability and allow their timely use, as soon as clinically indicated.

Treatment of refractory celiac disease type II (RCD II) and preventing the development of an enteropathy associated T-cell lymphoma in these patients is still difficult. In this case report, we describe a patient with RCD II who received fecal microbiota transfer as treatment for a recurrent Clostridium difficile infection, and remarkably showed a full recovery of duodenal villi and disappearance of celiac symptoms. This case suggests that altering the gut microbiota may hold promise in improving the clinical and histological consequences of celiac disease and/or RCD II.

Psychogenic amnesia is a complex disorder characterised by a wide variety of symptoms. Consequently, in a number of cases it is difficult distinguish it from organic memory impairment. The present study reports a new case of global psychogenic amnesia compared with two patients with amnesia underlain by organic brain damage. Our aim was to identify features useful for distinguishing between psychogenic and organic forms of memory impairment. The findings show the usefulness of a multidimensional evaluation of clinical, neuroradiological, neuropsychological and psychopathological aspects, to provide convergent findings useful for differentiating the two forms of memory disorder.

Pneumonitis and pneumonia after aspiration

Son, Young Gon; Shin, Jungho

2017-01-01

Aspiration pneumonitis and aspiration pneumonia are clinical syndromes caused by aspiration. These conditions are clinically significant due to their high morbidity and mortality. However, aspiration as a preceding event are often unwitnessed, particularly in cases of asymptomatic or silent aspiration. Furthermore, despite the difference in treatment approaches for managing aspiration pneumonitis and aspiration pneumonia, these two disease entities are often difficult to discriminate from one another, resulting in inappropriate treatment. The use of unclear terminologies hinders the comparability among different studies, making it difficult to produce evidence-based conclusions and practical guidelines. We reviewed the most recent studies to define aspiration, aspiration pneumonitis, and aspiration pneumonia, and to further assess these conditions in terms of incidence and epidemiology, pathophysiology, risk factors, diagnosis, management and treatment, and prevention.

Management of the difficult airway requires an appropriate approach based on personal clinical experiences. For every physician involved in rescue and emergency medicine, it is important to know the difficult airway algorithm and be familiar with alternative techniques of managing the difficult airway. We report a case of tracheal injury caused by multiple attempts at intubating the trachea. Based on current knowledge, apart from surgical equipment for cricothyroidotomy the laryngeal mask airway (LMA) and the Combitube (ETC) should be available on any ambulance vehicle staffed by an emergency physician. In future, blind intubation through the intubating laryngeal mask airway (ILMA) could offer a new opportunity.

Campylobacter jejuni (C. jejuni) bacteremia is difficult to diagnose in individuals with hematological disorders undergoing chemotherapy. The cause can be attributed to the rarity of this infection, to the variable clinical presentation, and to the partial overlapping symptoms underlying the disease. Here, we report a case of a fatal sepsis caused by C. jejuni in a 76-year-old Caucasian man with non-Hodgkin’s lymphoma. After chemotherapeutic treatment, the patient experienced fever associated with severe neutropenia and thrombocytopenia without hemodynamic instability, abdominal pain, and diarrhea. The slow growth of C. jejuni in the blood culture systems and the difficulty in identifying it with conventional biochemical phenotyping methods contributed to the delay of administering a targeted antimicrobial treatment, leading to a fatal outcome. Early recognition and timely intervention are critical for the successful management of C. jejuni infection. Symptoms may be difficult to recognize in immunocompromised patients undergoing chemotherapy. Thus, it is important to increase physician awareness regarding the clinical manifestations of C. jejuni to improve therapeutic efficacy. Moreover, the use of more aggressive empirical antimicrobial treatments with aminoglycosides and/or carbapenems should be considered in immunosuppressed patients, in comparison to those currently indicated in the guidelines for cancer-related infections supporting the use of cephalosporins as monotherapy.

To analyze the cause of misdiagnosis of occupational chronic n-hexane poisoning and to investigate the diagnosis and differential diagnosis of this disease. The clinical data of 16 patients with occupational chronic n-hexane poisoning who had been misdiagnosed with other diseases were collected. The hospital they first visited, cause of misdiagnosis, clinical features, and the misdiagnosis rate among inpatients during the same period were retrospectively analyzed. Sixteen of 62 patients hospitalized during the same period were misdiagnosed at the first visit; 11 cases were in the upper first-class hospitals, and 5 cases in the upper second-class hospitals; 5 cases were misdiagnosed as Green Barry syndrome, 2 cases as motor neuron disease, 2 cases as drug-induced peripheral neuropathy, 3 cases as periodic paralysis, and 4 cases had uncertain diagnosis. Most doctors who work in ordinary hospitals do not know occupational chronic n-hexane poisoning, which is often misdiagnosed as general neuropathies or difficult diseases. The key to correct diagnosis is to know the patient's occupational history and clinical features.

[Metastatic tumors in the ovary, difficulties of histologic diagnosis].

PubMed

Tamás, Judit; Vereczkey, Ildikó; Tóth, Erika

2015-09-01

The ovary is a common site of metastases. Secondary tumors account for 3-40% of all ovarian malignancies. Most ovarian metastases arise from the colon, although tumors of the breast, stomach and endometrium are also common places of origin. Clinical and histological features of metastatic tumors frequently mimic primary ovarian malignancies, causing serious diagnostic problems for the surgical pathologist. However, differentiation between primary ovarian cancer and ovarian metastasis is important in order to prevent inappropriate management and suboptimal treatment. The distinction between primary and secondary ovarian malignancies is especially difficult in cases when the metastasis is diagnosed before the primary tumor. Frozen section is widely used in the intra-operative assessment of patients with ovarian tumors but it can be very difficult to distinguish certain types of primary ovarian tumors and metastases from other sites. We examined 152 cases of secondary ovarian neoplasm diagnosed at the National Institute of Oncology, Hungary from 2000 to 2014. Colorectal cancer was the most common primary tumor (58 cases), followed by breast (33 cases), endometrium (30 cases) and stomach cancer (13 cases). The differential diagnosis proved the most difficult in cases when endometrioid and mucinous tumors were present in the ovaries. Metastases of colorectal and gastric adenocarcinomas may simulate benign or borderline cystadenomas too. In these cases the knowledge of the patient's history and immunohistochemical stains were helpful. In our study we discuss the diagnostic challenge of distinguishing these secondary ovarian tumors from primary ovarian neoplasms and the limits of the intraoperative frozen sections.

In some periodontal cases, biomechanical, esthetic, medical, or economic concerns make it difficult for clinicians to employ either traditional therapy or restoration with an implant-supported prosthesis. To avoid any compromise and ensure a good result in such cases, we chose a removable telescopic prosthesis on natural teeth. In this paper we present a new clinical and technical method for the telescopic prosthesis, and we show that this is a predictable, reliable solution that is easy to realize, inexpensive, and comfortable for patients.

Amyand's hernia, a rare entity in the surgical pathology, presupposes the presence of the vermiform appendix inside a inguinal hernia sac (1). The hernia sac peritonitis by appendix swelling is even more rare, very few cases being presented in the surgical literature (1). The preoperatory diagnosis of Amyand's hernia is therefore very difficult. We herein present the case of a 71-year old male patient, operated on an emergency basis for hernia, which eventually turned out to be Amyand's hernia, a case which determined us to research the literature dedicated to this topic.

Betel quid, chewing habits and difficult intubation: A case report and critical appraisal of evidence for practice.

Betel quid is used by 10-20% of world of population. Oral submucus fibrosis (OSF) is a chronic premalignant disease common in South Asian countries where betel quid is chewed. It is characterized by juxtaepithelial fibrosis of oral cavity and limited mouth opening, which can cause difficult intubation. A recent study in Taiwan has revealed long-term betel nut chewing is not predictor of difficult intubation. We describe two cases of OSF and critically analyze this study and its implications for clinical practice. OSF is now seen in Saudi Arabia and western countries with use of commercial betel quid substitutes. Although betel quid without tobacco is used in Taiwan, available evidence suggests rapid and early development of OSF where commercial chewing products like Pan Masala are used in India. Effects of betel quid may vary depending on the composition of quid and chewing habits. Studies where personal habits are involved must be analyzed carefully for external validity. Even though, Taiwan study is controlled, its validity outside Taiwan is highly questionable. Since OSF can cause unanticipated difficult intubation, thus during preanesthetic assessment, history of betel quid chewing, more importantly use of commercial chewing products is more likely to give clues to severity of OSF and possible difficult intubation. Further controlled trails in populations where commercial chewing products are used is necessary to detect association of chewing habits and difficult intubation.

To identify factors associated with adherence of implanted venous access port catheters in children and describe technical strategies for removing "stuck" ports. A retrospective single-center review of port removals was conducted between 2003 and 2012. Cases were identified through radiology reports. Clinical details (eg, demographics, disease, port dwell time, interventional techniques) were obtained through patient charts. Cases were classified as difficult removals if there was documented adherence to soft tissues or vein, or simple removals if no difficulty was recorded. Difficult removals were categorized and graded on increasing invasiveness of techniques required. Successful removal was defined as complete removal of the port catheter. Difficult removals were compared with simple removals for factors associated with difficult removal. Of all removals (N = 1,306), 58 were classified as difficult removals (4%). Using various techniques, 57 of 58 (98%) adherent port catheters were successfully removed. Factors identified with difficult removals included primary diagnosis of acute lymphoblastic leukemia (ALL) (78% vs 37%, P < .0001), age at insertion (3.7 y vs 5.4 y, P = .0019), and port dwell time (median 1,087 d vs 616 d, P < .0001). Difficulty removing port catheters in children is uncommon. Port catheters can usually be removed successfully using various IR techniques ranging in invasiveness. There is an association of difficult removal with early age at insertion, ALL diagnosis, and long port dwell time. Awareness of these factors may help physicians inform parents of potential difficulties and plan the removal procedure. Copyright © 2016 SIR. Published by Elsevier Inc. All rights reserved.

Teaching Evidence-Based Medicine in the Era of Point-of-Care Databases: The Case of the Giant Bladder Stone.

Kash, Melissa J

2016-01-01

In an era where physicians rely on point-of-care databases that provide filtered, pre-appraised, and quickly accessible clinical information by smartphone applications, it is difficult to teach medical students the importance of knowing not only when it is appropriate to search the primary medical literature but also how to do it. This column will describe how librarians at an academic health sciences library use an unusual clinical case to make demonstrations of searching primary medical literature real and meaningful to medical students, and to illustrate vividly the importance of knowing what to do when the answer to a clinical question cannot be found in a point-of-care database.

Clinical Management of Two Root Resorption Cases in Endodontic Practice

PubMed Central

2016-01-01

Root resorption is a pathological process involving loss of hard dental tissues. It may occur as a consequence of dental trauma, orthodontic treatment, and bleaching, and occasionally it accompanies periodontal disease. Although the mechanism of resorption process is examined in detail, its etiology is not fully understood. Wide open apical foramen is more difficult to manage and the root canal may often overfill. In this report we present two cases of root resorption and describe means for its clinical management. We conclude that useful measure of a success or failure in managing root resorption is the persistence of the resorption process. It is a clear sign of an active ongoing inflammatory process and shows the clinical need for retreatment. PMID:27648314

Primary cardiac lymphomas are rare entities (1.3% of all primary cardiac tumors) of difficult clinical identification. We report a case of a primitive cardiac lymphoma in a 35-year-old immunocompetent patient, presenting with signs and symptoms of cardiac tamponade. Echocardiography revealed a lateral atrioventricular mass associated with large pericardial effusion. After pericardiocentesis, surgical excision was performed. Chemotherapy regimens were administered according to established protocols and were effective in inducing complete remission at 6 months.

Aggressive osteoblastoma is a rare osteoid tissue forming tumour commonly affecting the spine with predilection for the posterior elements. Calvarial involvement is extremely rare with only two reported cases in the literature. Due to its overlapping clinical, radiographic and histological features with ossifying fibroma, benign osteoblastoma and osteosarcoma, it is very difficult accurately to diagnose this lesion at an early stage. A rare case of an aggressive osteoblastoma of the squamous temporal bone in a young male is presented here which was misdiagnosed twice before reaching the final diagnosis by correlating clinical, radiographic and histopathological features.

Cutaneous protothecosis is a rare infection caused by achlorophyllic algae of the genus Prototheca. The lesions usually occur on exposed areas, related with trauma, in immunocompromised patients. The most common clinical presentation is a vesicobullous and ulcerative lesion with pustules and scabs, simulating bacterial, fungal or herpetic infections or eczema. The diagnosis is determined by agent identification through histopathology, culture and the carbohydrates assimilation test. The finding of morula-like spherules is characteristic of Prototheca sp. Its rarity and non-specific clinical aspect may difficult the disease diagnosis. We report a case of a diabetic patient, in chronic use of systemic corticosteroids, that developed a skin lesion after trauma to the right leg. PMID:24346914

Pemphigus foliaceus is a chronic autoimmune disease of the skin, clinically characterized by scaly and crusty cutaneous erosions involving the seborrheic areas. The patient can eventually become erythrodermic. There are reports of atypical cases of pemphigus foliaceus with pustules and neutrophils, and clinical differentiation from generalized pustular psoriasis of von Zumbusch is difficult. We report the case of a 55-year-old man with a history of psoriasis vulgaris that has developed pemphigus foliaceus with pustules, triggered by withdrawal of systemic corticosteroids. This is the first report associating this atypical form of pemphigus with psoriasis, suggesting that an overlap with generalized pustular psoriasis can occur. PMID:29267466

Acute megakaryocytic leukemia (M7-AML) is a rare form of acute myeloid leukemia (AML), which is associated with poor prognosis. The case presented in the current report is a statement for the difficult diagnosis and clinical management of M7-AML in the context of a previous hematologic disorder of undetermined significance and associated genetic abnormalities. Probably, following the complete hematologic remission and further with induction chemotherapy plus tyrosine kinase inhibitor therapy, the clinical management of this case will be followed by a allogeneic bone marrow transplantation, the only proven therapy to improve overall survival.

After a hiatus of some 40 years, clinical research has resumed on the use of classic hallucinogens to treat addiction. Following completion of a small open-label feasibility study, we are currently conducting a double-blind placebo-controlled clinical trial of psilocybin-assisted treatment of alcohol use disorder. Although treatment effects cannot be analyzed until the study is complete, descriptive case studies provide a useful window into the therapeutic process of psychedelic-assisted treatment of addiction. Here we describe treatment trajectories of three participants in the ongoing trial to illustrate the range of experiences and persisting effects of psilocybin treatment. Although it is difficult to generalize from a few cases, several qualitative conclusions can be drawn from the data presented here. Although participants often find it difficult to describe much of their psilocybin experience, pivotal moments tend to be individualized, extremely vivid, and memorable. Often, the qualitative content extends beyond the clinical problem that is being addressed. The participants discussed in this paper experienced acute and lasting alterations in their perceptions of self, in the quality of their baseline consciousness, and in their relationship with alcohol and drinking. In these cases, experiences of catharsis, forgiveness, self-compassion, and love were at least as salient as classic mystical content. Finally, feelings of increased "spaciousness" or mindfulness, and increased control over choices and behavior were reported following the drug administration sessions. Ultimately, psilocybin-assisted treatment appears to elicit experiences that are extremely variable, yet seem to meet the particular needs of the individual.

Leprosy is a disease of declining global endemicity but is still an important health-care problem in India. Pure neural leprosy is an important subset of presentations of leprosy in India. Leprosy is a known disease of the skin and nerves, but cases of pure neural involvement are relatively less. We hereby present 10 cases of pure neural leprosy in which the diagnosis of leprosy was difficult with routine methods. The study was conducted at the main referral center and satellite clinics of our organization. A retrospective analysis of patient records for the last four years was undertaken to identify patients presenting with predominantly neurological manifestations and uncommon presentations including those without skin lesions. The medical records of the patients were used as source of data. All the patients were subjected to a detailed clinical examination and bacteriological examination with slit-skin smears. Investigations like nerve biopsy, electromyography, and nerve conduction studies were done in patients with diagnostic difficulties. Patients presented with neurological symptoms like paresthesias (60%), diminished sensations (40%), nonhealing ulcers (30%), and blisters (20%). All except one had thickened nerves on clinical examination. Slit-skin smear was negative in all but one patient. Nerve biopsy confirmed the diagnosis of leprosy in seven cases. Pure neural leprosy is difficult to diagnose with routine methods. The diagnosis should be considered, especially by neurologists and dermatologists, who are more likely to see such patients with predominant neural manifestations. The diagnosis should be confirmed with nerve biopsy to prevent delay in therapy and associated complications.

WHAT IS ALREADY KNOWN IN THIS AREA • The Simulated Surgery module of the MRCGP examination has been shown to be a valid and reliable assessment of clinical consulting skills. WHAT THIS WORK ADDS • This paper describes the further development of the methodology of the Simulated Surgery; showing the type of data analysis currently used to assure its quality and reliability. The measures taken to tighten up case quality are discussed. SUGGESTIONS FOR FUTURE RESEARCH The future development of clinical skills assessments in general practice is discussed. More work is needed on the effectiveness and reliability of lay assessors in complex integrated clinical cases. New methods to test areas that are difficult to reproduces in a simulated environment (such as acute emergencies and cases with the very young or very old) are also needed.

Development and pilot of Case Manager: a virtual-patient experience for veterinary students.

There is an increasing demand in veterinary education to engage students, teach and reinforce clinical reasoning, and provide access anytime/anywhere to quality learning opportunities. In addition, accrediting bodies are asking for more concrete documentation of essential clinical-skills outcomes. Unfortunately, during the clinical year in a referral hospital setting, students are at the mercy of chance regarding the types of cases they will encounter and the opportunities they will have to participate. Patient- and case-simulation technology is becoming more popular as a way to achieve these objectives in human and veterinary medical education. Many of the current options available to the veterinary medical education community to develop virtual-patient cases are too time-consuming, cost prohibitive, or difficult for the instructor or learner to use. In response, we developed a learning tool, Case Manager, which is low-cost and user-friendly. Case Manager was designed to meet the demands of veterinary education by providing students with an opportunity to cultivate clinical reasoning skills and allowing for real-time student feedback. We launched a pilot test with 37 senior veterinary medical students as part of their Small Animal Internal Medicine clinical rotation. Students reported that Case Manager increased their engagement with the material, improved diagnostic and problem-solving skills, and broadened their exposure to a variety of cases. In addition, students felt that Case Manager was superior to a more traditional, less interactive case presentation format.

Two cases of large adenomatoid odontogenic tumor seen recently in Senegal are thought to be the first cases of this type reported in West Africa. One patient was a 25 year old woman and the other an 11 year old boy, the clinical history and lesions being identical in both cases. Simple enucleation appeared to be the treatment of choice in view of the constantly reported benign nature of these tumors. It is difficult, or almost impossible however, to differentiate this tumor from dentigerous cyst on radiology, justifying routine minute pathologic examination of all operated paradental cysts.

Two clinical situations are presented where a heat-pressed leucite reinforced ceramic veneer system was used. For these situations the system was advantageous when veneers (1) required bulk or variable thicknesses or (2) were under load from function and parafunctional activity. This porcelain veneer system addressed some of the concerns associated with standard feldspathic porcelain and castglass systems. Practitioners should consider its use for situations that require a stronger veneer material.

Yokenella regensburgei belongs to the Enterobacteriaceae and shares some biochemical characteristics with Hafnia alvei. A few case reports have suggested that it is an opportunistic pathogen, but there is no strong evidence to support its clinical importance. Until recently, it was difficult to accurately differentiate between Y. regensburgei and H. alvei by use of routine identification techniques. Here, we present a case of soft tissue infection and bacteremia caused by Y. regensburgei, which was successfully treated by intravenous administration of ceftriaxone for three weeks, and review the previous literature.

Seizures are known to occur in Creutzfeldt-Jakob disease (CJD). In the setting of a rapidly progressive condition with no effective therapy, determining appropriate treatment for seizures can be difficult if clinical morbidity is not obvious yet the electroencephalogram (EEG) demonstrates a worrisome pattern such as status epilepticus. Herein, we present the case of a 39-year-old man with CJD and electrographic seizures, discuss how this case challenges conventional definitions of seizures, and discuss a rational approach toward treatment. Coincidentally, our case is the first report of CJD in a patient with Stickler syndrome.

2017-08-21

Communicating diagnostic news in health contexts is a potentially difficult event for all parties involved. However, despite this task's presence in the physician-patient context, it is rarely addressed during clinical training. The current study thus aimed to describe and evaluate how difficult news can be toned down during genetic counseling sessions involving cases of fetal syndromes and/or malformations. The study analyzed 33 naturalistic interactions (i.e. real situations), taped and transcribed, according to the theoretical and methodological perspective of Conversation Analysis, with an ethnomethodological basis. These interactions consisted of sessions in clinical genetics with pregnant women seen at the fetal medicine service of a reference hospital for maternal and child health in the Brazilian Unified National Health System (SUS). The analysis showed that communicating difficult news can be accompanied by optimistic perspectives that are scaled-up according to each situation's severity. In the absence of a positive diagnosis, the appointments can conclude with positive aspects such as recommendations for palliative care, so that the patient always leaves the appointment with some kind of recommendation. This study proposes to innovate and expand the scope of studies on communicating difficult news in the physician-patient relationship in Brazil, precisely by developing an analysis of real interactions in genetic counseling and thus providing interactional backing for training health professionals that deal with this challenge in their routine work.

Abstract The differential diagnosis of Crohn's disease (CD) and intestinal tuberculosis (ITB) remains difficult as the clinical symptoms of the 2 digestive diseases are so similar. Here we report a case where a patient was initially misdiagnosed with ITB prior to the correct CD diagnosis. The 46-year-old male patient was hospitalized elsewhere for pain in the right lower abdomen and underwent an appendectomy. The pathological diagnosis was ITB and the patient was administered antituberculosis therapy for 1 year. Afterward, the patient was readmitted to the hospital for a right lower abdominal mass. A computed tomography scan revealed intestinal gas, fistula, and abdominal mass. We performed a right hemicolectomy on the patient. Postoperatively, we diagnosed the patient with CD, based on patient history and pathological examination. According to the CD active index (CDAI), the patient was at high risk and began treatment with infliximab. The patient has remained in complete remission and made a good recovery after 8-months follow-up. We compared this case with the results of a literature review on the misdiagnosis between CD and ITB (26 previously reported cases) to determine the characteristics of misdiagnosed cases. We found that distinguishing between ITB and CD is difficult because of their varied clinical presentation, nonspecific investigative tools, and profound similarities even in pathological specimens. Although a CT scan to determine the morphology of the bowel wall is a key for correct diagnosis, each case still poses challenges for diagnosis and administrating the appropriate treatment.

Difficult end-of-life treatment decisions: do other factors trump advance directives?

PubMed

Hardin, Steven B; Yusufaly, Yasmin A

2004-07-26

Advance directives are widely promoted as a means to plan for patients' decisional incapacity, yet there is little evidence of their effectiveness. We devised a study to assess physicians' compliance with hypothetical advance directives and further examine their clinical reasoning. The study consisted of an analysis of a mailed written survey containing 6 hypothetical cases of seriously ill patients. Each case contained an explicit advance directive with potential conflict between the directive and (1) prognosis, (2) wishes of family or friends, or (3) quality of life. Data were collected on the clinical treatment decisions made by physicians and the reasons for those decisions. Study participants were all internal medicine faculty and resident physicians from a single academic institution. A total of 47% analyzable surveys (117/250) were returned. Decisions by faculty and residents were not consistent with the advance directive in 65% of cases. This inconsistency was similar for faculty and residents (68% and 61%, respectively; P>.05). When physicians made decisions inconsistent with the advance directive, they were more likely to list reasons other than the directive for their decisions (89%; P<.001). Internists frequently made treatment decisions that were not consistent with an explicit advance directive. In difficult clinical situations, internists appear to consider other factors such as prognosis, perceived quality of life, and the wishes of family or friends as more determinative than the directive. Future work needs to explore the generalizability of these findings and examine how strictly patients desire their advance directives to be followed.

Since bladder injury has no specific clinical symptoms, accurate diagnosis at first consultation is relatively difficult. To elucidate the clinical characters type of injury, clinical symptoms, laboratory findings, methods of therapy and diagnosis, we reviewed 15 patients with bladder injury over a 9-year-period 1990-1998 (10 were traumatic injuries and 5 spontaneous injuries). We found no specific clinical symptom of bladder injury. Bladder injury may occur anywhere in the bladder wall, but most commonly occurred at the dome of the bladder (60.0%). Gross hematuria was not seen in 40.0% of the cases. The accuracy of diagnosis at first consultation was relatively low (46.7%) and the tendency to make a misdiagnosis as acute abdomen on digestive organs was found. Of the traumatic injuries 60% were afflicted in the drunken state, so alcohol intoxication was considered as an important enviromental factor of bladder injury. Surgical repair of injury sites was employed in 11 cases (73.3%: 7 were intraperitoneal injuries, 4 were extraperitoneal injuries), 4 cases were managed with indwelling urethral catheter. With appropriate treatment, the prognosis is excellent.

The present case report refers to a multiorgan autoimmune disease manifesting following thymectomy performed for a benign thymoma. This disease is characterized by hypothyroidism, severe myasthenia, polymyositis and alopecia which are organ-specific diseases probably with a different time of onset but which are all an expression of the same immunopathologic process occurring in individuals who have a genetic predisposition. Characteristic of the present case is not only the association of the different immunopathologic clinical pictures but also the rather difficult differential diagnosis between a hypothyroidism-related myopathy and polymyositis. It was possible to formulate the diagnosis by integrating the results of clinical and laboratory evaluation with the therapeutic outcome. The onset of the syndrome was attributed to the withdrawal, following surgery, of the inhibitory effects of the thymoma on some clones of autoreactive lymphocytes.

Combined treatment with immunoadsorption and rituximab leads to fast and prolonged clinical remission in difficult-to-treat pemphigus vulgaris.

Pemphigus vulgaris (PV) is a potentially life-threatening autoimmune bullous disorder which is characterized by blisters and erosions of the skin and mucous membranes. A frequently applied first-line therapy for PV consists of systemic corticosteroids (CS) combined with immunosuppressive agents. In refractory cases, novel therapeutic strategies such as immunoadsorption (IA) and the anti-CD20 antibody rituximab (Rtx) aim at directly interfering with pathogenic autoantibodies (auto-Abs). To investigate the long-term efficacy of IA in combination with Rtx in patients with difficult-to-treat PV, we assessed the clinical response to treatment by monitoring the Autoimmune Bullous Skin Disorder Intensity Score, IgG auto-Abs against desmoglein 1 and 3 (Dsg1 and Dsg3) and the dose of systemic CS. We retrospectively analysed clinical and serological parameters of 10 patients with difficult-to-treat PV who received IA at 4-week intervals, followed by Rtx either twice at 1000 mg or four times at 375mg m(-2) . During a 12-month follow-up period, CS were tapered according to the individual clinical status. Six months after the first IA treatment eight of 10 patients were in complete remission on therapy while one patient showed a partial response and one patient was unresponsive to the treatment. At 12 months, six of eight patients were in complete remission on therapy, one patient showed stable disease and one patient had relapsed. Overall, anti-Dsg3 IgG and anti-Dsg1 IgG auto-Abs correlated well with the clinical activity and systemic CS were tapered gradually. The present findings show that the combination of IA and Rtx induces rapid clinical remission and long-term control in difficult-to-treat pemphigus. © 2011 The Authors.

Reggars, John W.

1993-01-01

A common clinical presentation in the Chiropractor's office is that of vague and unilateral paraesthesia of the wrist or hand. Often the patient is unable to identify any definite dermatomal pattern and in such cases an accurate diagnosis becomes somewhat difficult. The following paper, incorporating a flow chart, provides the clinician with a logical sequence for the clinical exam in an attempt to arrive at the correct diagnosis, particularly those with mechanical causes.

An increase in cases of pertussis, mainly in young infants, has been reported in the last few years. The clinical presentation of this disease is very similar to that produced by respiratory syncytial virus (RSV), which makes the diagnosis difficult. To compare the clinical and epidemiological characteristics between Bordetella pertussis and RSV infections in infants admitted to hospital. An analytical matched case-control study was conducted during the period 2008-2011. Cases were defined as infants admitted with pertussis confirmed by PCR in nasopharyngeal aspirate. Each case was matched by age, sex and date of admission to two controls defined as patients with RSV infection detected by immunochromatography in nasal aspirate. Demographic, clinical, laboratory data were compared. Seventy eight patients (26 cases of pertussis and 52 controls RSV+) were included. Sociodemographic characteristics were similar in both groups. Cases had more days of symptoms prior to admission, longer hospital stays, and increased frequency of epidemic family environment. Apnoea and cyanosis were more frequent. Cases of pertussis were more likely to have apnoea, cyanosis, and lymphocytosis while RSV infections had more frequent fever, vomiting and respiratory distress. The clinical presentations of pertussis and RSV infection are similar, but there are some characteristics that can help to distinguish between them.

Copy number variations (CNVs) are genomic structural variations (deletions, duplications, or translocations) that represent the 4.8-9.5% of human genome variation in healthy individuals. In some cases, CNVs can also lead to disease, being the etiology of many known rare genetic/genomic disorders. Despite the last advances in genomic sequencing and diagnosis, the pathological effects of many rare genetic variations remain unresolved, largely due to the low number of patients available for these cases, making it difficult to identify consistent patterns of genotype-phenotype relationships. We aimed to improve the identification of statistically consistent genotype-phenotype relationships by integrating all the genetic and clinical data of thousands of patients with rare genomic disorders (obtained from the DECIPHER database) into a phenotype-patient-genotype tripartite network. Then we assessed how our network approach could help in the characterization and diagnosis of novel cases in clinical genetics. The systematic approach implemented in this work is able to better define the relationships between phenotypes and specific loci, by exploiting large-scale association networks of phenotypes and genotypes in thousands of rare disease patients. The application of the described methodology facilitated the diagnosis of novel clinical cases, ranking phenotypes by locus specificity and reporting putative new clinical features that may suggest additional clinical follow-ups. In this work, the proof of concept developed over a set of novel clinical cases demonstrates that this network-based methodology might help improve the precision of patient clinical records and the characterization of rare syndromes.

Foot and ankle injuries (FAI) are very common, with about 6000 cases per day in France. Unlike lateral ankle sprain (LAS), the diagnosis of midtarsal joint sprain (MJS, also known as Chopart's joint sprain) is not widely known. This prospective study aims to detail the epidemiology of MJS and compare it to LAS. The study was conducted within our institution over a period of 16 months. Patients with clinical signs predictive of MJS without radiographic bone lesion underwent ultrasound assessment. MJS was diagnosed in case of at least 1 lesion of the dorsal midtarsal joint ligaments. A total of 2412 patients consulted for FAI; 188 had clinical and radiographic criteria for ultrasound examination. Eighty-two cases of MJS were diagnosed (3.4% of FAIs). Sports injuries were more frequent in MJS (P=0.04), and mechanisms more varied than in LAS, with inversion injury in 75% of cases and plantar hyperflexion in 22%. Sprain was severe in 70% of cases, with complete ligament tear. Clinical and ultrasound analyses correlated in only 40% of cases of MJS, versus 98% for LAS. MJS is frequent, difficult to diagnose clinically, and often severe. Clinical presentation and injury mechanisms differ from ankle sprain. Ultrasound seems to be an indispensable tool in diagnosis.

A Distance Blended Learning Program to Upgrade the Clinical Competence of District Non-doctor Anesthesia Providers in Nepal.

PubMed

Shah, Shristi; Knoble, Stephen; Ross, Oliver; Pickering, Stephen

2017-12-01

Across Nepal, anesthesia at a district level is provided mostly by non-doctor anesthesia providers (anesthesia assistants-AAs). Nepal's Government recognized the need to sustain competence with continuous professional development and to upgrade 6-month trained working AAs to professional equivalence with the new national standard of 12-month training. As they are essential district health workers and AA clinical training sites are full, an innovative distance blended learning, competency-based, upgrade 1-year course was developed and conducted in 2014-2017 for two batches. The course content was developed over 18 months by a team of Nepali and overseas AA training experts. The 1-year course started with a refresher course, continued with tablet-based 12-month self-learning modules and clinical case logs, regular educational mentor communication, midcourse 2-week contact time in an AA training site, regular text messaging and ended with clinical examination and multiple-choice questions. Tablet content included 168 new case studies, pre- and posttests, video lectures, matching exercises and a resource library. All module work and logged clinical cases were uploaded centrally, where clinical mentors were able to review work. Clinical skills were upgraded, as needed, through direct clinical contact midway through the course. Quantitative and qualitative course assessments were included. Fourteen working AAs in first batch and eight working AAs in second batch from district, zonal and mission hospitals across Nepal were enrolled. All remained working at their hospitals throughout the course, and there were no significant tablet problems inhibiting course completion. Twenty-one AAs completed all modules successfully with time required for module completion averaging 19.2 h (range 11.2-32). One AA left the course after 3 months with a personal problem. Subjectively, AAs felt that the obstetric and pediatric modules were more difficult; lowest marks were objectively seen in the airway module. Clinical mentors averaged 8.2 h mentoring review work per module with direct student communication of 2.9 h per module per month. Participants logged a total of 5473 clinical cases, ranging between 50 and 788 cases each. Complications were recorded; outcomes were good. Challenges were the national IT infrastructure making data synchronization difficult and the lack of clinical exposure at some AA's hospitals. Nineteen AAs attended the final examination, and all passed. Two AAs withdrew before the final examination period due to personal and logistic reasons. This is the first use of distance blended learning to upgrade district health workers in Nepal and perhaps for non-doctor anesthesia providers globally. Key success factors were motivated students, cultural and contextualized clinical content, good educational mentoring relationships with regular communication, central IT and motivational support, and face-to-face midcourse clinical contact time.

Tibial periostitis frequently occurs in athletes. We present our experience with MRI in a series of 7 patients (11 legs) with this condition. The clinical presentation and scintigraphic scanning suggested the diagnosis. MRI exploration of 11 legs demonstrated a high band-like juxta-osseous signal enhancement of SE and IR T2 weighted sequences in 6 cases, a signal enhancement after i.v. contrast administration in 4. Tibial periostitis is a clinical diagnosis and MRI and scintigraphic findings can be used to assure the differential diagnosis in difficult cases with stress fracture. MRI can visualize juxta-osseous edematous and inflammatory reactions and an increased signal would appear to be characteristic when the band-like image is fixed to the periosteum.

Neurosarcoidosis is a great mimicker. It is often difficult to diagnose particularly when there is no prior history of systemic sarcoidosis. Although certain sites of the neuraxis are more commonly involved than others, any site of the central or peripheral nervous system can be affected. We report a case of sarcoidosis involving the cauda equina in a 38-year-old African American male without prior history of systemic disease. Initial clinical presentation was suggestive of Guillian-Barré syndrome, but the evaluation proved this case to be neurosarcoidosis involving the cauda equina. We have followed this patient for 8 years, and he remains clinically stable on prednisone 5 mg/day.

Streptococcus suis is a global endemic swine pathogen. S. suis can cause meningitis, endocarditis and severe sepsis in humans, who are exposed to swine. Human infection with S. suis was first reported in 1968, since then, human infections have been sporadic although an outbreak in China counted 215 cases. In a rare case of disseminated arthritis we found that correct clinical diagnosis was difficult due to unspecific symptomatology and slow growing bacterial culture. However, conducting thorough examinations is crucial, and if treated correctly the outcome is favourable.

A case report is used to illustrate the difficult differential diagnostic dilemma between depression and Cushing's disease that has led to extensive scientific collaboration to test the hypothesis that both diagnoses may fall within a pathophysiological continuum. Unique to the collaborative study underway is the commitment of psychiatric clinical investigators to bring state of the art techniques for studying neurobiology in a disease traditionally viewed as medical, and of endocrinologists to address their expertise in a disease viewed primarily as psychiatric.

Clinico-pathological features of kidney disease in diabetic cases.

Diabetic kidney disease is the major cause of end-stage kidney disease in developed countries. However, the onset of kidney disorder and the progression pattern of kidney dysfunction and proteinuria greatly vary cases by cases. Therefore, risk classification with clinical data and pathological findings is important. Recent clinico-pathological study with kidney biopsy samples from diabetic patients revealed that pathological changes of diabetic nephropathy are characteristic and have special impacts on prognosis in each clinical stage. Moreover, comparison of the clinico-pathological findings of diabetic nephropathy with hypertensive nephrosclerosis revealed that there are few differences in their pathological findings in cases with low albuminuria and preserved estimated glomerular filtration rate (eGFR). Because it is so difficult to clearly distinguish pure kidney lesions caused by diabetes and kidney lesions due to effects other than diabetes, it is vital that these overlapped pathological findings be confirmed on kidney biopsy in cases of early stage diabetes. Further research is warranted regarding the pathogenesis of diabetic nephropathy and indication of kidney biopsy in diabetic cases.

BACTERIAL MENINGITIS AND OTHER DISEASES AFFECTING THE MENINGES—A Review of 349 Cases

PubMed Central

Cover, William L.

1949-01-01

Three hundred and forty-nine cases of disease affecting the meninges were observed at the San Bernardino County Charity Hospital in an eight year period. A total of 29 patients with meningococcal, H. influenzae and pneumococcal meningitis were treated. There were four deaths, of which three occurred during the first 24 hours in the hospital. Of 22 cases of unclassified meningitis, four probably were tuberculous, four probably were meningococcal and two probably were of virus origin. Under present treatment programs the differentiation between viral and bacterial meningitides is difficult and it is possible, therefore, that the reported incidence of the two groups may not represent the facts. Of 22 cases of unclassified meningitis, 12 had no specific characteristics which would permit a clinical diagnosis. One of the patients died. Of 70 cases of clinical meningitis, the infecting organism was identified in 69 per cent. Meningococcal meningitis made up only 17 per cent of 70 cases of purulent meningitis observed between July 1, 1945, and July 1, 1948. PMID:18137216

A case study of a time-limited interpersonal psychotherapy group (IPT-G) is presented to illustrate the use of interpersonal therapy (IPT) to treat patients with major depression in a group psychotherapy format. The use of individual outcome measures as a helpful adjunct to clinical psychotherapeutic practice is demonstrated. Because IPT-G has only a few exclusion criteria (active suicidality and significant borderline personality features), it can be used in a broad range of clinical settings. This clinical example demonstrates IPT-G to be a useful modality for addressing a common and difficult patient population. PMID:11121007

Enterobiasis is one of the most common human parasitic infections. It is considered an intestinal parasite, but cases of extra-intestinal affections exist, notably infections of the female genital tract. Enterobius vermicularis (EV) eggs (or ova) have been found in the cervical smears of two patients in our institute during the last 16 years. No gynaecological or gastrointestinal symptoms were reported, and there was no known intestinal infection in these two cases. A review of the available literature revealed rare cases of vaginal enterobiasis, with a wide range of clinical presentations, many patients being asymptomatic. The diagnosis may sometimes be difficult, mainly because of the lack of clinical suspicion. However, cytological identification of EV in cervico-vaginal smears is important, especially when considering the risk of ascending infections of the genital tract associated with severe complications. © 2017 Wiley Periodicals, Inc.

Primary bone lymphoma (PBL) is a rare disease, accounting for >1% of all cases of malignant lymphoma. Diffuse large B-cell lymphoma (DLBCL) is the most common histological type of PBL. The present study reported the case of a 68-year-old male with primary bone DLBCL, originally occurred in the sternum, which is a rare form of presentation. Computed tomography (CT), magnetic resonance imaging and bone emission CT were performed, followed by immunohistochemical analysis of a biopsy specimen, and the results were used to establish the diagnosis. At the time of diagnosis, no osseous involvement was observed. The clinical, radiological and histological features of PBL can mimic other medical conditions, thereby making the diagnosis difficult, and frequently leading to delays in treatment. The present study investigated the clinical features, management and prognosis of PBL, and reviewed previous relevant cases. PMID:26137117

Scabies is an important public health problem in residential care homes. Delayed diagnosis contributes to outbreaks, which may be prolonged and difficult to control. We investigated factors influencing outbreak recognition, diagnosis and treatment, and staff experiences of outbreak control, identifying areas for intervention. We carried out a semi-structured survey of managers, affected residents and staff of seven care homes reporting suspected scabies outbreaks in southern England over a 6-month period. Attack rates ranged from 2% to 50%, and most cases had dementia (37/39, 95%). Cases were diagnosed clinically by GPs (59%) or home staff (41%), none by dermatologists. Most outbreaks were attributable to avoidably late diagnosis of the index case. Participants reported considerable challenges in managing scabies outbreaks, including late diagnosis and recognition of outbreaks; logistically difficult mass treatment; distressing treatment processes and high costs. This study demonstrates the need for improved support for care homes in detecting and managing these outbreaks.

Medical students face numerous stressors during their clinical years, including difficult clinical events. Fostering resilience is a promising way to mitigate negative effects of stressors, prevent burnout, and help students thrive after difficult experiences. However, little is known about medical student resilience. To characterize medical student resilience and responses to difficult clinical events during clinical training. Sixty-two third-year (MS3) and 55 fourth-year (MS4) University of Chicago medical students completed surveys in 2016 assessing resilience (Connor Davidson Resilience Scale, CD-RISC 10), symptoms of burnout, need for resilience training, and responses to difficult clinical events. Medical student mean resilience was lower than in a general population sample. Resilience was higher in males, MS4s, those without burnout symptoms, and students who felt able to cope with difficult clinical events. When students experienced difficult events in the clinical setting, the majority identified poor team dynamics among the most stressful, and agreed their wellbeing was affected by difficult clinical events. A majority also would prefer to discuss these events with their team later that day. Students discussed events with peers more than with attendings or residents. Students comfortable discussing stress and burnout with peers had higher resilience. Most students believed resilience training would be helpful and most beneficial during MS3 year. Clinical medical student resilience was lower than in the general population but higher in MS4s and students reporting no burnout. Students had some insight into their resilience and most thought resilience training would be helpful. Students discussed difficult clinical events most often with peers. More curricula promoting medical student resilience are needed.

Tuberculous meningitis causes substantial mortality and morbidity in children and adults. More research is urgently needed to better understand the pathogenesis of disease and to improve its clinical management and outcome. A major stumbling block is the absence of standardised diagnostic criteria. The different case definitions used in various studies makes comparison of research findings difficult, prevents the best use of existing data, and limits the management of disease. To address this problem, a 3-day tuberculous meningitis workshop took place in Cape Town, South Africa, and was attended by 41 international participants experienced in the research or management of tuberculous meningitis. During the meeting, diagnostic criteria were assessed and discussed, after which a writing committee was appointed to finalise a consensus case definition for tuberculous meningitis for use in future clinical research. We present the consensus case definition together with the rationale behind the recommendations. This case definition is applicable irrespective of the patient's age, HIV infection status, or the resources available in the research setting. Consistent use of the proposed case definition will aid comparison of studies, improve scientific communication, and ultimately improve care. Copyright © 2010 Elsevier Ltd. All rights reserved.

Separating generalized anxiety disorder from major depression using clinical, hormonal, and structural MRI data: A multimodal machine learning study.

2017-03-01

Generalized anxiety disorder (GAD) is difficult to recognize and hard to separate from major depression (MD) in clinical settings. Biomarkers might support diagnostic decisions. This study used machine learning on multimodal biobehavioral data from a sample of GAD, MD and healthy subjects to differentiate subjects with a disorder from healthy subjects (case-classification) and to differentiate GAD from MD (disorder-classification). Subjects with GAD ( n  = 19), MD without GAD ( n  = 14), and healthy comparison subjects ( n  = 24) were included. The sample was matched regarding age, sex, handedness and education and free of psychopharmacological medication. Binary support vector machines were used within a nested leave-one-out cross-validation framework. Clinical questionnaires, cortisol release, gray matter (GM), and white matter (WM) volumes were used as input data separately and in combination. Questionnaire data were well-suited for case-classification but not disorder-classification (accuracies: 96.40%, p  < .001; 56.58%, p  > .22). The opposite pattern was found for imaging data (case-classification GM/WM: 58.71%, p  = .09/43.18%, p  > .66; disorder-classification GM/WM: 68.05%, p  = .034/58.27%, p  > .15) and for cortisol data (38.02%, p  = .84; 74.60%, p  = .009). All data combined achieved 90.10% accuracy ( p  < .001) for case-classification and 67.46% accuracy ( p  = .0268) for disorder-classification. In line with previous evidence, classification of GAD was difficult using clinical questionnaire data alone. Particularly cortisol and GM volume data were able to provide incremental value for the classification of GAD. Findings suggest that neurobiological biomarkers are a useful target for further research to delineate their potential contribution to diagnostic processes.

Plasmodium vivax malaria vaccines: why are we where we are?

Reyes-Sandoval, Arturo; Bachmann, Martin F

2013-12-01

Malaria is one of the few diseases in which morbidity is still measured in hundreds of millions of cases every year. Plasmodium vivax and Plasmodium falciparum are responsible for nearly all the malaria cases in the world and despite difficulties in obtaining an exact number, estimates indicate an astonishing 349-552 million clinical cases of malaria due to P. falciparum in 2007 and between 132-391 million clinical episodes due to P. vivax in 2009. It is becoming evident that eradication of malaria will be an arduous task and P. vivax will be one of the most difficult species to eliminate and perhaps become the last standing malaria parasite. Indeed, in countries that succeed in decreasing the disease burden, nearly all the remaining malaria cases are caused by P. vivax. Such resilience is mainly due to the sophisticated mechanism that the parasite has evolved to remain dormant for months or years forming hypnozoites, a small structure in the liver that will be a major hurdle in the efforts toward malaria eradication. Furthermore, while clinical trials of vaccines against P. falciparum are making fast progress, a very different picture is seen with P. vivax, where only few candidates are currently active in clinical trials.

Traumatic tricuspid insufficiency is a rare condition. The diagnosis is difficult because of the slow progression of this pathology and the presence of more clinically acute lesions. Non-penetrating chest trauma is responsible for 90% of cases. Echocardiography is the investigation of choice for assessing the mechanism of the tricuspid regurgitation and for diagnosing associated lesions. It should be performed systematically in patients with multiple trauma. The surgical indications are difficult to determine and depend on the patients' symptoms and the type of anatomical lesions. It should be undertaken before right ventricular myocardial dysfunction. Several techniques may be used from valvuloplasty to valve replacement mainly with bioprostheses in symptomatic patients.

Dedifferentiated chondrosarcoma of the larynx is a rare and highly malignant tumor. We present the report of a 59-year-old man with dedifferentiated laryngeal chondrosarcoma, which was difficult to diagnose even under microscopic examination. The original diagnosis was an aneurysmal bone cyst, and the final diagnosis was established only after careful consideration of the imaging, surgical, and microscopic findings. In clinical practice, there are many similarities between dedifferentiated chondrosarcoma and aneurysmal bone cysts. Furthermore, it is difficult to identify dedifferentiated laryngeal chondrosarcoma with a giant-cell malignant mesenchymal component. This report describes our experience and discusses this phenomenon.

Children suffering from difficult-to-control asthma (DCA) require frequent appointments with their physician, complex treatment regimes and often admissions to hospital. Less than 5% of the asthmatic population suffer this condition. DCA must be correctly characterised to rule out false causes of DCA and requires making a differential diagnosis from pathologies that mimic asthma, comorbidity, environmental and psychological factors, and analysing the factors to determine poor treatment compliance. In true DCA cases, inflammation studies (exhaled nitric oxide, induced sputum, broncho-alveolar lavage and bronchial biopsy), pulmonary function and other clinical aspects can classify DCA into different phenotypes which could make therapeutic decision-making easier.

This retrospective analysis reviews the clinical experience of a major urban referral hospital with diffuse malignant pleural mesothelioma during the 14-year period from 1973 through 1986. Seventy-five cases of definite or equivocal mesothelioma were identified. There were four cases of primary malignant peritoneal mesothelioma, seven cases of benign fibrous mesothelioma, and 64 cases of diffuse malignant pleural mesothelioma. In 43 cases (67%) of diffuse malignant pleural mesothelioma, there was historic evidence of asbestos exposure. In 21 cases (33%), there was no known history of asbestos exposure. An increase in annual incidence of diffuse malignant pleural mesothelioma was observed over themore » study period, from three cases in 1973 to ten cases in 1986. Despite greater awareness of this disease, the diagnosis remains a difficult one to establish given the nonspecific symptoms, signs and radiographic appearance, variable histologic appearance, and poor diagnostic sensitivity and specificity of thoracentesis and closed pleural biopsy. Thoracotomy, thoracoscopy, and CT-guided needle biopsies gave higher yields and are the diagnostic measures of choice when diffuse malignant pleural mesothelioma is suspected.« less

Primary intestinal lymphangiectasia is a lymphatic system's disorder, where lymphatic drainage is blockaged. Clinically it produces malabsorption, protein-losing enteropathy, hypogammaglobulin in blood, and several degrees of malnutrition. Its treatment is not easy and includes dietetic-therapy and drugs. A 35-year-old-woman case report is exposed. She has recurrent chylosa ascites, requiring several admissions and evacuatory paracentesis. After food-fat was replaced by medium-chain triacyl-glicerol-enriched diet, a clinical, analytical and anthropometric improvement was demonstrated. The major way of treatment in intestinal lymphangiectasia in this case is the employement of specific-diet and adaptaded-basic-food. It's difficult and high collaboration of the patient is required, being necessary medical revisions during the whole life, due to the not well known evolution of this long-standing disease.

Ruisi, Michael; Ruisi, Phillip; Rosero, Hugo; Schweitzer, Paul

2013-01-01

Prinzmetal angina or vasospastic angina is a clinical phenomenon that is often transient and self-resolving. Clinically it is associated with ST elevations on the electrocardiogram, and initially it may be difficult to differentiate from an acute myocardial infarction. The vasospasm induced in this setting occurs in normal or mildly to moderately diseased vessels and can be triggered by a number of etiologies including smoking, changes in autonomic activity, or drug ingestion. While the ischemia induced is usually transient, myocardial infarction and life-threatening arrhythmias can occur in 25% of cases. We present the case of a 65-year-old female where repetitive intermittent coronary vasospasm culminated in transmural infarction in the setting of gastrointestinal bleeding. This case highlights the mortality associated with prinzmetal angina and the importance of recognizing the underlying etiology.

To describe cytology patterns in low-grade adenosquamous carcinomas (LGASCs) of the breast. Low-grade adenosquamous carcinomas of the breast are a recently described rare variant of primary metaplastic carcinomas characterized by clinical indolence, slow evolution and excellent survival. To date, only 7 cases of LGASC were studied cytologically, and it was demonstrated that LGASC identification was difficult because its cellular components exhibited unspecific and nonsuspicious features. They consisted of irregularly clustered cells without prominent cytonuclear atypia, mitosis or necrosis. The presence of metaplastic cells or keratin debris was helpful in accurate tumor typing. We report here 3 additional cases of LGASC that were initially studied by fine-needle aspiration. We have also encountered diagnostic difficulties and misdiagnosed tumors, since 2 cases were underdiagnosed as 'suspicious' and only 1 was accurately diagnosed as malignancy. The review of our cases and the literature confirms that, despite its putative metaplastic origin, LGASC is an entity which is difficult to diagnose using classical cytological methods. Moreover, core-needle biopsy as well as frozen sections may also misdiagnose LGASC as a benign breast lesion. © 2014 S. Karger AG, Basel.

To investigate clinical aspects and a new operative method for resecting third branchial fistula. The clinical aspects of 4 patients with third branchial fistula were retrospectively analyzed. It is difficult to locate the inner orifice of fistula through neck path due to tiny diameter of inner orifice. The inner orifice could be found and closed effectively by inserting yellow zebra guidewire from sinus piriformis with gastroscope. The mucous membrane of sinus piriformis could not be damaged due to the soft pointed end of yellow zebra guidewire. 4 cases were treated successfully without pharyngeal fistula or recurrent laryngeal nerve injury. No recurrent infections were found in all cases with follows-up of 6-66 months. Ineffectiveness of radiography with meglumine diatrizoate or oral administration of methylene blue before operation indicates tiny fistula. In this case, resection of third branchial fistula with the assistance of gastroscope and yellow zebra guidewire under general anesthesia can be performed. This innovative method of diagnosis and treatment is worth of application clinically.

Answering pages from nurses about patients in need of immediate attention is one of the most difficult challenges a resident faces during their first days as a physician. A Mock Page program has been developed and adopted into a national surgical resident preparatory curriculum to prepare senior medical students for this important skill. The purpose of this study is to assess standardized mock page cases as a valid construct to assess clinical decision making and interprofessional communication skills. Mock page cases (n = 16) were administered to 213 senior medical students from 12 medical schools participating in a national surgical resident preparatory curriculum in 2013 and 2014. Clinical decision making and interprofessional communication were measured by case-specific assessments evaluating these skills which have undergone rigorous standard-setting to determine pass/fail cut points. Students' performance improved in general for both communication and clinical decision making over the 4-week course. Cases have been identified that seem to be best suited for differentiating high- from low-performing students. Chest pain, pulmonary embolus, and mental status change cases posed the greatest difficulty for student learners. Simulated mock pages demonstrate an innovative technique for training students in both effective interprofessional communication and management of common postoperative conditions they will encounter as new surgical interns.

A New CT-Guided Modified Trocar Technique for Drainage of Difficult Locations Abscesses

Tyng, Chiang J., E-mail: chiangjengtyng@gmail.com; Amoedo, Maurício K.; Bohrer, Yves

PurposeComputed tomography (CT) is commonly used to guide drainage of deep-seated abdominal fluid collections. However, in some cases, these collections seem to be inaccessible due to surrounding organs or their being in difficult locations. The aim of this study is to describe a modified Trocar technique to drain collections in difficult locations, especially those in the subphrenic space, without passing through intervening organs.Materials and MethodsThis retrospective case series study describes seven inpatients who underwent CT-guided drainage using a modified Trocar technique for abscesses that are difficult to access percutaneously. All patients provided written informed consent prior to the procedure. Aftermore » placement of a 12–14F catheter inside the peritoneum, the Trocar stylet was removed so that the tip of the catheter became blunt and flexible to avoid injury to organs and structures in the catheter route, and the catheter was slowly advanced towards the collection using CT guidance and tactile sensation. After reaching the target, the stylet was reintroduced to enter the abscess wall.ResultsAll procedures were performed using an anterior abdominal wall access with adequate catheter positioning and resulted in clinical status improvement in the days after the drainage. No complications related to the procedure were identified in any of the patients.ConclusionsThe modified Trocar technique for percutaneous CT-guided drainage of abdominal abscesses may be feasible for lesions that are difficult to access with conventional methods.« less

Perceptually-oriented hypnosis: removing a socially learned pathology and developing adequacy: the case of invisible girl.

PubMed

Woodard, Fredrick James

2014-10-01

This is the first case review to explicate perceptual hypnotic principles such as differentiation, characteristics of an adequate personality, and the need for adequacy, as utilized in clinical hypnosis in a complex case that altered the distorted perceptions and personal meanings of an eleven-year-old girl who believed that she had Bipolar Disorder and her body and mind were damaged. This qualitative case study examines aspects of hypnosis during therapy from a perceptual point of view to illustrate frustrations in difficult cases and identify some of the causes and origins of alleged clinical pathology in adverse environments. Some moments of effective self-healing through supporting internally controlled changes in perception during hypnotic experiencing are highlighted rather than externally focusing on observed thoughts and behavior. Factors relevant to social psychological research, such as family dynamics, poverty, and interactions with social service agencies and institutions, creating learned pathology, are pointed out for future research.

Bladder transitional cell carcinoma and BK virus in a young kidney transplant recipient.

Kidney transplant recipients have a heightened risk of developing neoplasms. Immunosuppressive treatments decrease the incidence of transplant rejection but increase the risk of infections, including BK virus (BKV). This infection is acquired in childhood and remains latent in the renal and urinary epithelium. In cases of immunodeficiency, BKV has been implicated as a tumor virus, but the role of BKV in cancer is a controversial topic and is difficult to determine. In the tumor cells, it is possible to detect fragments of the viral genome that could alter the control mechanisms of the cell cycle and DNA repair. We report the case of a kidney transplant recipient who developed BKV nephropathy and carcinoma of the bladder, supporting a possible role for BKV in the oncogenic pathway in this clinical setting, but the role of BKV in cancer remains a controversial topic and difficult to determine. © 2012 John Wiley & Sons A/S.

ASB Clinical Biomechanics Award Paper 2010: Virtual Pre-Operative Reconstruction Planning for Comminuted Articular Fractures

2010-01-01

Background Highly comminuted intra-articular fractures are complex and difficult injuries to treat. Once emergent care is rendered, the definitive treatment objective is to restore the original anatomy while minimizing surgically induced trauma. Operations that use limited or percutaneous approaches help preserve tissue vitality, but reduced visibility makes reconstruction more difficult. A pre-operative plan of how comminuted fragments would best be re-positioned to restore anatomy helps in executing a successful reduction. Methods In this study, methods for virtually reconstructing a tibial plafond fracture were developed and applied to clinical cases. Building upon previous benchtop work, novel image analysis techniques and puzzle solving algorithms were developed for clinical application. Specialty image analysis tools were used to segment the fracture fragment geometries from CT data. The original anatomy was then restored by matching fragment native (periosteal and subchondral) bone surfaces to an intact template, generated from the uninjured contralateral limb. Findings Virtual reconstructions obtained for ten tibial plafond fracture cases had average alignment errors of 0.39 (0.5 standard deviation) mm. In addition to precise reduction planning, 3D puzzle solutions can help identify articular deformities and bone loss. Interpretation The results from this study indicate that 3D puzzle solving provides a powerful new tool for planning the surgical reconstruction of comminuted articular fractures. PMID:21215501

2017-01-01

We present a case of severe acquired acrodermatitis enteropathica in a vegan adult female with multiple underlying comorbidities. Acquired acrodermatitis enteropathica or zinc-deficiency dermatitis is the most common diagnosis than many practitioners realize with up to 10% of the patients in developed nations with the risk of zinc deficiency. The condition can be difficult to diagnose due to many similarly-presenting conditions. Furthermore, comorbid conditions in the patients can serve as confounders to the diagnosis. The symptoms are often extremely distressing for the patients, though the treatment is simple and clinical improvement occurs rapidly with appropriate care. We recommend a high index of suspicion to practitioners as well as a low-threshold for initiating treatment in the patients with any clinical symptoms of the condition. PMID:29152424

Jejunal Metastasis Colliding With a Borderline Tumor in the Ovary: A Hitherto Unreported Eventuality.

Piana, Simonetta; Giunta, Alessandro; Valli, Riccardo

2015-10-01

Metastatic adenocarcinomas to the ovary can show morphologically innocuous areas simulating primary benign lesions or borderline tumors. Ruling out a metastasis can be a difficult issue for pathologists, especially when facing with cystic tumors. Because of the important clinical implications of differentiating metastatic adenocarcinomas from primary ovarian tumors, the integration of clinical, pathological, and immunohistochemical features is warranted, primarily in case of mucinous adenocarcinomas. Vice versa, the synchronous presence of a metastasis and a primary in the same ovary is virtually excluded as a very unlikely eventuality. Here, we describe a case of metastatic adenocarcinoma from the jejunum colliding with a seromucinous borderline tumor in the same ovary, an unreported eventuality so far. © The Author(s) 2015.

The Basel clinic for parents with infants and toddlers is a special interdisciplinary service. The authors present the concept and practice of treatment. Further they show the results of documentation and evaluation. In most cases regulation and sleeping disorders are treated. Temperament ratings made by the mothers of the treated children exhibit more difficult behaviour in comparison to a normal sample. These ratings had no correlation with the mothers' depression scores which rank much higher than the control group. The outcome ratings by the psychotherapists show that despite the short duration of the treatment and severe cases therapeutical success could be achieved. This outlines the importance of such specialized services for early infant crying and other disturbances of the early childhood.

2009-04-01

Botulism is a rare disease in Chile and of the known clinical presentation, infant botulism is the most common. We report the case of a previously healthy seven month old male infant with a two weeks history of rinorrea, cough, fatigue, constipation and progressive weakness after the consumption of honey. Stool cultures were positive for Clostridium botulinum group 1 type A and electromyography was compatible with the diagnosis. The patient evolved with arterial hypertension, interpreted as secondary to autonomic dysfunction, which responded to calcium channel blockers. Muscle tone improved progressively during the following four weeks. Infant botulism is a potentially fatal disease; diagnosis can be difficult given the broad clinical manifestations. Prevention should focus on education of parents of infants as well as medical personnel.

Congenital Tuberculosis as a Result of Disseminated Maternal Disease: Case Report

Trujillo-Honeysberg, Mónica; Diazgranados-Cuenca, Lucy

2015-01-01

Although tuberculosis is highly prevalent worldwide, congenital tuberculosis is one of the least common manifestations of the disease. The diagnosis is usually difficult because of the non-specific clinical presentation and the lack of awareness of maternal disease prior to pregnancy and delivery. We present the case of a preterm neonate with congenital tuberculosis, born to a previously healthy mother who had developed severe disseminated tuberculosis during her pregnancy. Once the diagnosis was confirmed in the mother, the congenital infection was confirmed by isolation of Mycobacterium tuberculosis in gastric aspirates, and positive polymerase chain reaction in a cerebrospinal fluid examination. Treatment for tuberculosis with a four-drug regimen resulted in an adequate clinical response in both the mother and infant. PMID:26508944

Distinguishing papillary endothelial hyperplasia and angiosarcoma on core needle biopsy of the breast: The importance of clinical and radiologic correlation.

2018-02-24

Papillary endothelial hyperplasia (PEH) is a rare non-neoplastic exuberant organizing hematoma that can closely mimic angiosarcoma due to a resemblance to malignant anastomosing blood vessels. It could be particularly difficult to distinguish PEH from angiosarcoma in breast core needle biopsies. We identified all cases of these lesions diagnosed on core needle biopsy in order to identify clinical, radiologic, and pathologic features that could prove helpful to arrive at the correct diagnosis. Four cases of PEH and 4 cases of angiosarcoma were identified. The mean age at diagnosis was 62 for PEH and 33 for primary angiosarcoma. All cases of PEH formed small masses with circumscribed or lobulated margins by imaging (mean size 0.9 cm). In 3 cases, the masses were difficult or impossible to identify after the biopsy. Angiosarcomas presented as larger masses with ill-defined margins (mean size 2.8 cm) that were unchanged in size after biopsy. PEH was surrounded by adipose tissue, whereas angiosarcoma invaded into fibrous stroma and involved lobules. The pseudopapillary structures of PEH were composed mainly of collagen, and thus, additional histologic stains for fibrin were not helpful for diagnosis. The 4 patients with PEH received no further treatment and are alive and disease-free at 2-11 years of follow-up. In contrast, the patients with angiosarcoma underwent mastectomy and chemotherapy or radiation therapy. Two of the patients with angiosarcoma died 3 years after diagnosis and the other 2 patients are alive without disease at 5 and 6 years. Therefore, distinguishing PEH and angiosarcoma is essential for appropriate management. This is the first series to compare these lesions on core needle biopsy and the first to note important clinical, imaging, and histologic differences that aid in making a diagnosis of PEH with confidence on breast core needle biopsy. © 2018 Wiley Periodicals, Inc.

Beyond PubMed: Searching the "Grey Literature" for Clinical Trial Results.

PubMed

Citrome, Leslie

2014-07-01

Clinical trial results have been traditionally communicated through the publication of scholarly reports and reviews in biomedical journals. However, this dissemination of information can be delayed or incomplete, making it difficult to appraise new treatments, or in the case of missing data, evaluate older interventions. Going beyond the routine search of PubMed, it is possible to discover additional information in the "grey literature." Examples of the grey literature include clinical trial registries, patent databases, company and industrywide repositories, regulatory agency digital archives, abstracts of paper and poster presentations on meeting/congress websites, industry investor reports and press releases, and institutional and personal websites.

Among organ transplant recipients, cytomegalovirus (CMV) commonly results in various types of infection such as pneumonitis, hepatitis, and enterocolitis. However, CMV peritonitis is very rare and difficult to diagnose owing to lack of visible clinical signs. We present a case of a 35-year-old female kidney recipient who developed abdominal pain and urinary retention caused by CMV peritonitis. To our knowledge, this is the first case report of CMV peritonitis after organ transplantation to be diagnosed through histopathological examination. © 2017 John Wiley & Sons A/S.

Trichotillomania is a neglected psychiatric disorder characterized by the urge to pull out the hair, the eyebrows or any other hair, but rarely the eyelashes. In the Diagnostic and Statistical Manual of Mental Disorders it is defined as habits and pulses disturbance. We here report the case of a girl with trichotillomania involving her left eyelashes due to low self-esteem. The disease may be episodic but it is usually chronic and difficult to treat. Given the possible clinical and psychiatric complications, early and accurate diagnosis is essential. Cognitive-behavioral therapy is the gold standard treatment.

While pneumatosis cystoides intestinalis (PCI) is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated with massive peritoneal free air and/or retroperitoneal air that mimicked perforated peritonitis. These cases highlight the clinical importance of PCI that mimics perforated peritonitis, which requires emergency surgery. Preoperative imaging modalities and diagnostic laparoscopy are useful to make an accurate diagnosis.

The full metallic double-J ureteral stent (MS) was introduced as a method for providing long-term drainage in malignant ureteral obstruction. Experimental evaluation of the MS revealed that its mechanical features allow efficient drainage in difficult cases, which could not be managed by the insertion of a standard polymeric double-J stent. Clinical experience with the MS showed controversial results. Careful patient selection results in efficient long-term management of malignant ureteral obstruction. The use of the MS should also be considered in selected benign cases. Major complications are uncommon and the minor complications should not hinder its use. Experience in pediatric patients is limited and warrants additional study. The cost-effectiveness of the MS seems to be appropriate for long-term treatment. Further investigation with comparative clinical trials would document the outcome more extensively and establish the indications as well as the selection criteria for the MS. PMID:25624569

Giant-cell tumors are an infrequent clinical, radiological, and pathological entity observed in 5% of primary bone tumors. They generally occur at the epiphysis of long bones, particularly in the knee area but patellar localization seems very rare. Despite their perfectly benign histological aspect, giant-cell tumors may be aggressive, leading to local recurrence or even distant metastasis to the lung. We report a case of benign giant-cell tumor of the patella with lung metastasis observed in a 23-year-old woman. The aggressive radiological image was suggestive of chondrosarcoma. Histologically the differential diagnosis with chondroblastoma was difficult. The tumor and lung metastasis were treated by surgical resection. Four years later there has been no recurrence. We present the anatomic and clinical aspects of giant-cell tumor of the bone together with the diagnostic approach and the clinical course.

Sarcoidosis is a multisystemic granulomatous disease of unknown origin. Chronic cutaneous lupus erythematosus (CCLE) is an autoimmune disease that is associated with autoantibody production and T-cell dysfunction. Cutaneous manifestations of sarcoidosis may mimic CCLE and vice versa making it difficult to reach a diagnosis clinically. We present a case of a 57-year-old woman with long-standing sarcoidosis who presented to clinic with diffuse painful plaques that were very distinct and suggestive of CCLE. She had a family history of both sarcoidosis and CCLE. The patient was immediately started on topical corticosteroids and oral hydroxychloroquine. Skin biopsy and the absence of direct immunofluorescence confirmed a skin manifestation of her previously diagnosed sarcoidosis, despite the clinical morphology favoring classic CCLE. Sarcoidosis may have diverse manifestations and may mimic other disease processes. A detailed history along with a low threshold for biopsy is important for determining a diagnosis.

It is an hereditary disease transmitted by a different mode of inheritance: mitochondrial, X-linked recessive and autosomal recessive. The beginning of clinical manifestations is varied and occurs usually in the first two years of life, with progressive and insidious evolution and exacerbation periods. Diagnosis is difficult because pleomorphic presentation, based on clinical findings and complementary study related to mitochondrial production of ATP and cytochrome c oxidase deficiencies. Considering that there is no specific treatment, this is based on a palliative procedure. So, the identification of this syndrome is very important to keep it under control, since its evolution is progressive.

Lobomycosis or lacaziosis is a chronic granulomatous fungal infection caused by Lacazia loboi. Most cases are restricted to tropical regions. Transmission is believed to occur through traumatic inoculation in the skin, mainly in exposed areas. It is characterized by keloid-like nodules. There are only a few hundred cases reported. The differential diagnoses include many skin conditions, and treatment is difficult. The reported case, initially diagnosed as keloid, proved to be refractory to surgical treatment alone. It was subsequently approached with extensive surgery, cryotherapy every three months and a combination of itraconazole and clofazimine for two years. No signs of clinical and histopathological activity were detected during follow-up. PMID:29723380

INTRODUCTION Meckel's diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1–3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult. PRESENTATION OF CASE We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel's diverticulum causing intussusception. DISCUSSION Intestinal obstruction in patients with Meckel's diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture. CONCLUSION Consideration of Meckel's diverticulum although a rare diagnosis is imperative and this case raises the question “should surgeons routinely examine the bowel for Meckel's diverticulum at laparoscopy?” PMID:22288035

Congenital pulmonary vascular abnormalities arise from several etiologies. These anomalies are difficult to categorize and sorted into distinct classifications. Major pulmonary vascular abnormalities can be ranked as interruption of the main pulmonary artery or its absence, emergence of the left pulmonary artery in the right pulmonary artery, pulmonary venous drainage abnormalities, and pulmonary arteriovenous malformations (PAVMs). Some of the cases are asymptomatic and diagnosed by coincidence, whereas a few of them are diagnosed by typical findings in the newborn and infancy period, symptoms, and radiological appearances. Early diagnosis is important, since death may occur as a result of pulmonary and cardiac pathologies developed in patients with pulmonary vascular anomalies. In this case presentation, the clinical and radiological findings of patients that presented with different complaints and were diagnosed with pulmonary vascular anomalies were introduced.

A Series of Unfortunate Events: Prinzmetal Angina Culminating in Transmural Infarction in the Setting of Acute Gastrointestinal Hemorrhage

PubMed Central

2013-01-01

Prinzmetal angina or vasospastic angina is a clinical phenomenon that is often transient and self-resolving. Clinically it is associated with ST elevations on the electrocardiogram, and initially it may be difficult to differentiate from an acute myocardial infarction. The vasospasm induced in this setting occurs in normal or mildly to moderately diseased vessels and can be triggered by a number of etiologies including smoking, changes in autonomic activity, or drug ingestion. While the ischemia induced is usually transient, myocardial infarction and life-threatening arrhythmias can occur in 25% of cases. We present the case of a 65-year-old female where repetitive intermittent coronary vasospasm culminated in transmural infarction in the setting of gastrointestinal bleeding. This case highlights the mortality associated with prinzmetal angina and the importance of recognizing the underlying etiology. PMID:24826293

2012-01-01

Localized scleroderma is a rare disease, characterized by sclerotic lesions. A variety of presentations have been described, with different clinical characteristics and specific prognosis. In scleroderma en coup de sabre (LScs) the atrophic lesion in frontoparietal area is the disease hallmark. Skin and subcutaneous are the mainly affected tissues, but case reports of muscle, cartilage, and bone involvement are frequent. These cases pose a difficult differential diagnosis with Parry-Romberg syndrome. Once considered an exclusive cutaneous disorder, the neurologic involvement present in LScs has been described in several case reports. Seizures are most frequently observed, but focal neurologic deficits, movement disorders, trigeminal neuralgia, and mimics of hemiplegic migraines have been reported. Computed tomography and magnetic resonance imaging have aided the characterization of central nervous system lesions, and cerebral angiograms have pointed to vasculitis as a part of disease pathogenesis. In this paper we describe the clinical and radiologic aspects of neurologic involvement in LScs. PMID:22319646

Moral Conflicts and Religious Convictions: What Role for Clinical Ethics Consultants?

PubMed

Moskop, John C

2018-05-03

Moral conflicts over medical treatment that are the result of differences in fundamental moral commitments of the stakeholders, including religiously grounded commitments, can present difficult challenges for clinical ethics consultants. This article begins with a case example that poses such a conflict, then examines how consultants might use different approaches to clinical ethics consultation in an effort to facilitate the resolution of conflicts of this kind. Among the approaches considered are the authoritarian approach, the pure consensus approach, and the ethics facilitation approach described in the Core Competencies for Healthcare Ethics Consultation report of the American Society for Bioethics and Humanities, as well as a patient advocate approach, a clinician advocate approach, and an institutional advocate approach. The article identifies clear limitations to each of these approaches. An analysis of the introductory case illustrates those limitations, and the article concludes that deep-seated conflicts of this kind may reveal inescapable limits of current approaches to clinical ethics consultation.

To report a case of coexisting systemic lupus erythematosus (SLE) and sickle cell disease (SCD) with a review of the literature on the topic. Report of case and research of the association between SLE and SCD in literature through scientific articles in health sciences databases, such as LILACS, MEDLINE/Pubmed and Scielo, until May 2012. Descriptors used: 1. Sickle cell anemia; 2. Sickle cell disease; 3. Systemic lupus erythematosus; 4. Hemoglobinopathies. The authors describe an association between SLE and SS hemoglobinopathy in an eight-year-old female patient displaying articular, hematologic and neuropsychiatric manifestations during clinical evolution. Forty-five cases of association between SLE and SCD are described in literature, mostly adult (62.2%), women (78%) and with the SS phenotype in 78% of the cases, and different clinical manifestations. Compared with our patient, articular, hematologic and neuropsychiatric manifestations were present in 76%, 36% and 27% of the cases, respectively. SLE and SCD are chronic diseases that have several clinical and laboratory findings in common, meaning difficult diagnosis and difficulty in finding the correct treatment. Although the association between these diseases is not common, it is described in literature, so it is imperative that physicians who treat such diseases be alert to this possibility.

Case series Patient: — Final Diagnosis: — Symptoms: Skin lesions Medication: — Clinical Procedure: — Specialty: Dermatology Objective: Unusual or unexpected effect of treatment Background: Vitiligo, also known as leukoderma, is an autoimmune skin condition that results in the loss of melanin pigment. Vitiligo is not a rare condition but is difficult to treat and is associated with psychological distress. Case Reports: A series of 14 cases of vitiligo are presented that were treated with individualized homeopathic remedies that were based on plant, animal, or mineral compounds. There were 13 women and one man in the case series, with a mean age 29.8 years, and a mean follow-up from treatment of 58 months. The mean time between the onset of the appearance of vitiligo and the first consultation at our clinic was 96 months. Homeopathic treatment for patients is holistic and was performed on an individualized basis as described in this case series. Photographic images of the skin are presented before and after treatment. Conclusions: In 14 patients with vitiligo treated with individualized homeopathy, the best results were achieved in the patients who were treated in the early stages of the disease. We believe that homeopathy may be effective in the early stages of vitiligo, but large controlled clinical studies are needed in this area. PMID:29196612

Mycetoma or Maduramycosis is a localized chronic suppurative infection characterized by exuberant granulation tissue, discharging sinuses, and bone involvement later in the course of the disease. Early clinical diagnosis before the appearance of sinuses and grains (aggregates of organism surrounded by granulation tissue, which are discharged from the draining sinuses) is difficult. Delay in diagnosis may lead to amputation of the affected part. Definitive diagnosis is through biopsy and microbiological examination. However, at times diagnosis may still be difficult. The recently described “dot in circle” sign on magnetic resonance imaging (MRI) is easy to recognize and highly specific. We present a case of mycetoma foot with characteristic MRI features.

National hospitals in developing countries command a disproportionate share of medical care budgets, justified on the grounds that they have a more difficult patient case mix and higher occupancy rates than decentralized district hospitals or clinics. This paper empirically tests the hypothesis by developing direct measures of the severity of patient illness, hospital case-mix and a resource intensity index for each of El Salvador's public hospitals. Based on an analysis of inpatient care staffing requirements, national hospitals are found to receive funding far in excess of what case-mix and case-load considerations would warrant. The findings suggest that significant system-wide efficiency gains can be realized by allocating hospital budgets on the bases of performance-related criteria which incorporate the case-mix approach developed here.

The endobronchial tuberculosis (EBTB) is an uncommon type of tuberculosis. The respiratory symptoms in EBTB are usually nonspecific and misleading. The aim of the study is to determine the clinical features and diagnostic aspects of EBTB. Twenty-eight cases of endobronchial tuberculosis collected from January 2009 to October 2015. EBTB was found in 16 females and 12 males. The mean age was 48 years. The history of tuberculosis and tuberculosis contagion were not found in any case. The respiratory symptoms were dominated by cough and dyspnea. Hemoptysis was found in 7 cases. The chest X-ray showed associated pulmonary lesions in 26 cases. Bronchoscopy finded an endobronchial granular lesion in 15 cases, a tumorous pattern in 7 cases; a thickening spurs in 4 cases and ganglio-bronchial fistula in two cases. Bronchial biopsies had found a caseo-follicular tuberculosis in 27 cases. Pleural biopsy confirmed associated pleural tuberculosis in one case. The research of Koch bacillus in the sputum was positive in 13 cases and culture in 6 cases. The antituberculosis treatment was started in all patients and an oral corticosteroids treatment was associated in 5 cases. The evolution was good in 26 cases. This study showed clinical, radiological and endoscopic bronchial tuberculosis polymorphism making its diagnosis difficult and the importance of a bacteriological and/or histological confirmation.

Non-tuberculous mycobacteria (NTM) cause prosthetic knee joint infections in rare cases. Infections with rapidly growing non-tuberculous mycobacteria (RGNTM) are difficult to treat due to their aggressive clinical behavior and resistance to antibiotics. Infections of a prosthetic knee joint by RGNTM have rarely been reported. A standard of treatment has not yet been established because of the rarity of the condition. In previous reports, diagnoses of RGNTM infections in prosthetic knee joints took a long time to reach because the condition was not suspected, due to its rarity. In addition, it is difficult to identify RGNTM in the lab because special identification tests are needed. In previous reports, after treatment for RGNTM prosthetic infections, knee prostheses could not be re-implanted in all cases but one, resulting in arthrodesis or resection arthroplasty; this was most likely due to the aggressiveness of these organisms. In the present report, two cases of prosthetic knee joint infection caused by RGNTM (Mycobacterium abscessus) are described that were successfully treated, and in which prosthetic joints were finally reimplanted in two-stage revision surgery.

To estimate the accuracy of the clinical diagnosis of the three most common causes of acute vulvovaginal symptoms (bacterial vaginosis, candidiasis vaginitis, and trichomoniasis vaginalis) using a traditional, standardized clinical diagnostic protocol compared with a DNA probe laboratory standard. This prospective clinical comparative study had a sample of 535 active-duty United States military women presenting with vulvovaginal symptoms. Clinical diagnoses were made by research staff using a standardized protocol of history, physical examination including pelvic examination, determination of vaginal pH, vaginal fluid amines test, and wet-prep microscopy. Vaginal fluid samples were obtained for DNA analysis. The research clinicians were blinded to the DNA results. The participants described a presenting symptom of abnormal discharge (50%), itching/irritation (33%), malodor (10%), burning (4%), or others such as vulvar pain and vaginal discomfort. According to laboratory standard, there were 225 cases (42%) of bacterial vaginosis, 76 cases (14%) of candidiasis vaginitis, 8 cases (1.5%) of trichomoniasis vaginalis, 87 cases of mixed infections (16%), and 139 negative cases (26%). For each single infection, the clinical diagnosis had a sensitivity and specificity of 80.8% and 70.0% for bacterial vaginosis, 83.8% and 84.8% for candidiasis vaginitis, and 84.6% and 99.6% for trichomoniasis vaginalis when compared with the DNA probe standard. Compared with a DNA probe standard, clinical diagnosis is 81-85% sensitive and 70-99% specific for bacterial vaginosis, Candida vaginitis, and trichomoniasis. Even under research conditions that provided clinicians with sufficient time and materials to conduct a thorough and standardized clinical evaluation, the diagnosis and, therefore, subsequent treatment of these common vaginal problems remains difficult.

We report the case of a presenile woman with Cotard syndrome, in the context of major depression, who showed an improvement in bilateral frontal hypoperfusion in a SPECT study using 99mTc-HMPAO after undergoing successful treatment with antidepressant therapy. We also retrospectively evaluated her clinical course based on the clinical stages. The symptoms of Cotard syndrome have been reported to change dramatically according to the stages. This peculiarity made it difficult for us to rapidly diagnose Cotard syndrome in the context of major depression, and not dementia, and thereby adequately treat the patient in our case. Differences in the reduced blood flow regions and a time lag from psychiatric remission were observed before the improvement in the SPECT findings when comparing our case with a previously reported case of Cotard syndrome. These differences suggest that the mechanism of Cotard syndrome is still not well understood at the present time.

Recurrent laughter-induced syncope.

2012-07-01

Syncope is a common presenting complaint in Neurology clinics or Emergency departments, but its causes are sometimes difficult to diagnose. Apart from vasovagal attacks, other benign, neurally mediated syncopes include "situational" syncopes, which occur after urination, coughing, swallowing, or defecation. A healthy 42-year-old male patient presented to the neurology clinic with a long history of faints triggered by spontaneous laughter, especially after funny jokes. Physical and neurological examination, and electroencephalography and magnetic resonance imaging were unremarkable. There was no evidence to suggest cardiogenic causes, epilepsy, or cataplexy and a diagnosis of laughing syncope was made. Laughter-induced syncope is usually a single event in the majority of cases, but may present as recurrent attacks as in our case. Some cases occur in association with underlying neurological conditions. Prognosis is good in the case of neurally mediated attacks. Laughter may not be recognized by physicians as a cause of syncope, which may lead to unnecessary investigations or misdiagnosis, and affect patients' quality of life.

Fine-needle biopsy (FNB) has been reported as a rapid, minimally invasive technique for the diagnosis of metastatic melanoma. The diagnostic accuracy of FNB was assessed in a consecutive series of 2,204 FNBs of clinically suspicious lesions from patients with previous primary melanomas treated at the Sydney Melanoma Unit, Sydney, Australia, between January 1992 and December 2002. The sensitivity and specificity of FNB were 96.3% and 98.9%, respectively. There were 5 false-positive cases (0.6%), which were verified as metastatic adenocarcinoma (3 cases) or reactive processes (organizing hematoma and chronic osteomyelitis, 1 each). False-negative diagnoses (6.7% of cases) were associated with a variety of clinicopathologic factors, including difficult-to-access anatomic sites (eg, high axilla or deep inguinal), small lesions, and lesional characteristics such asfibrosis, necrosis, or cystic change. FNB is a highly accurate, rapid, and cost-effective procedure for the diagnosis of metastatic melanoma and should be considered as the initial diagnostic procedure of choice in patients with melanoma with clinically suspected metastases.

A solitary tuberculous brain lesion (STBL) can be difficult to distinguish from a glioma, metastasis or other infectious disease, especially from a pyogenic brain abscess. We analyzed the clinical characteristics, diagnostic procedures and outcomes of 24 patients with STBL diagnosed in three centers from France, India and Mexico. We also reviewed 92 STBL cases previously reported in the literature. General symptoms were found in 54% of our patients, including enlarged lymph nodes in 20%. Cerebrospinal fluid was typically abnormal, with lymphocytic pleocytosis and a high protein level. The lung CT scan was abnormal in 56% of patients, showing lymphadenopathy or pachipleuritis. Brain MRI or CT was always abnormal, showing contrast-enhanced lesions. Typically, MRI abnormalities were hypointense on T1-weighted sequences, while T2-weighted sequences showed both a peripheral hypersignal and a central hyposignal. The diagnosis was documented microbiologically or supported histologically in 71% of cases. Clinical outcome was good in 83% of cases. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

[New therapeutic strategies for the treatment of difficult wounds].

2008-05-01

The medical-surgical treatment of the difficult wounds represents a socio-sanitary problem in continuous growth, currently involving in our Country around 2,000,000 people. The "difficult wound" is a loss of cutaneous substances, usually due to multifactorial pathogenesis, that do not spontaneously lead to a complete recovery. Numerous studies in the literature have evidenced that the use of the advanced wound dressings allows to reach the best clinical and economic results in the process of recovery of the difficult wounds. The advanced would dressing assures a longer period of permanence on the injury and shorten the time of treatment and, as a consequence, it is required a smaller number of applications in comparison with the traditional medications. The Wound Bed Preparation (WBP) can be defined as the global and coordinate management of the cutaneous injury, enabling to chip off the local barriers to the recovery, or promoting the effectiveness of the innovative therapeutic instruments. The term advanced wound dressing indicates the dressing material having biocompatibility characteristics. The purpose of the advanced wound dressings is the one to create the ideal environment for the cicatrization process and isolate the wound from traumas and external infections. The "Difficult Wounds" Unit of the Department of Plastic and Reconstructive Surgery of the Policlinico Umberto I in Rome, from January to December 2006, treated 570 patients (308 men and 262 women), whose age was between 2 days and 85 years, affected by ulcers of various nature. Among our cases, 200 patients were selected and randomly separated in two different groups: group A consisting of 100 patients entirely treated with traditional medications; group B composed by 100 patients treated with advanced dressings. Every patient has locally been treated with periodic and specific medications, according to the type of difficult wound, and subsequently they proceeded to find out how to treat the systemic factors causing ulcer. The patients underwent 3 times a week to medications in those cases presenting infection signs and 2 times a week in those cases where no infection signs were shown, for period varying from 1 month up to one year for the chronic forms. The results showed a higher percentage of recovery reached by using the advanced dressings. Group A showed the followings results: the 53% of patients recovered from wounds; the remaining 47% patients did'nt not recover but in 17% cases medications showed to be of some help in the preparation of the vascular bed for the execution of a definitive operation (application of grafts or local edges), while the remaining 30% has shown a scarce improvement of the injury and they are still under treatment. Group B showed the 65% of patients recovered from wounds; as for the remaining 35% not recovered patients, medications represented an auxiliary aid to the preparation of the vascular bed for the execution of a definitive operation (application of grafts or local edges) for the 15% of patients, while the remaining 20%, even if not completely recovered, showed a notable improvement of the injury (reduction of the dimensions and disappearance of the infection and improvement of the patient quality of life). In synthesis, it emerges that the advanced dressings, if correctly used, offer advantages in terms of clinical effectiveness (rapid recovery from the injury), patient quality of the life and cheapness. It has also to be considered that the difficult wound is often the epiphenomenon of a systemic illness. The difficult wound requires, therefore, a multidisciplinary treatment.

Canine polyneuropathy is a neurological disorder characterized by a dysfunction of multiple peripheral nerves. The etiology of the disease is diverse; it may occur in cases of infectious, immune-mediated, or hereditary conditions or in association with endocrinopathy, neoplasm, or chemical intoxication. It is often difficult to determine the etiology through clinical symptoms. The aim of this study is to investigate pathological differences among three canine polyneuropathy cases with each presumably having a different etiology. Cases included a 13-month-old female border collie (Dog No.1), a 21-month-old male chihuahua (Dog No.2) and an 11-year-old male beagle (Dog No.3). Clinical examinations revealed hindlimb ataxia and sensory loss in Dog No.1, forelimb paralysis and vertebral pain in Dog No.2, and paddling-gait and hypothyroidism in Dog No.3. Histopathologically, axonal swelling and pale myelin were observed in Dog No.1. Giant axons mimicking giant axonal neuropathy were obvious in Dog No.2. Dog No.3 showed atrophic axons and severe interstitial edema. Distributions of peripheral nerve lesions coincided with respective clinical symptoms. According to their clinical and pathological features, Dogs No.1 and No.2 were suspected of hereditary polyneuropathy, while Dog No.3 seemed to have hypothyroidism-associated polyneuropathy. As each case demonstrated unique pathological features, different pathogeneses of peripheral nerve dysfunction were suggested.

Nickel-Titanium Single-file System in Endodontics.

Dagna, Alberto

2015-10-01

This work describes clinical cases treated with a innovative single-use and single-file nickel-titanium (NiTi) system used in continuous rotation. Nickel-titanium files are commonly used for root canal treatment but they tend to break because of bending stresses and torsional stresses. Today new instruments used only for one treatment have been introduced. They help the clinician to make the root canal shaping easier and safer because they do not require sterilization and after use have to be discarded. A new sterile instrument is used for each treatment in order to reduce the possibility of fracture inside the canal. The new One Shape NiTi single-file instrument belongs to this group. One Shape is used for complete shaping of root canal after an adequate preflaring. Its protocol is simple and some clinical cases are presented. It is helpful for easy cases and reliable for difficult canals. After 2 years of clinical practice, One Shape seems to be helpful for the treatment of most of the root canals, with low risk of separation. After each treatment, the instrument is discarded and not sterilized in autoclave or re-used. This single-use file simplifies the endodontic therapy, because only one instrument is required for canal shaping of many cases. The respect of clinical protocol guarantees predictable good results.

The occurrence of acne in dialysed renal failure patients has rarely been reported and the clinical characteristics and therapeutic issues rarely studied in these patients. Two men and two women, 33 to 56 years-old, with chronic renal failure and no past history of acne, developed severe acne under dialysis. The acne was excoriated in all cases and associated with prurigo-like lesions and intense pruritus, which made diagnosis difficult. Acne was profuse on the face and the trunk, but also on the neck (1 case) and the upper limbs (2 cases). No patient was taking acne-inducing substances. Various to therapies attempting to control pruritus were ineffective. However, anti-acne treatments (cyclines associated with local tretinoin in 1 case and oral isotreninoin in 3 cases) led to complete regression of the acne, pruritus and the prurigo-like lesions without relapse after a follow-up time of 4 months to 2 years. Pruritus is frequent during renal failure. However, the occurrence of unexplained acne has only rarely been reported. Our patients' clinical picture was original, characterized by the late development, under dialysis, of severe and pruriginous acne, the pathogenesis of which is unknown. Because of the clinical and therapeutic implications (impaired quality of life, pigmentation or scarring and remarkable efficacy of oral isotretinoin) this clinical picture merits more attention, and the modalities for the prescription of isotretinoin in this context should be defined.

To present a case of expansive focal cemento-osseous dysplasia and emphasize the importance of differential diagnosis. Cemento-osseous dysplasia is categorized into three subtypes on the basis of the clinical and radiographic features: Periapical, focal and florid. The focal type exhibits a single site of involvement in any tooth-bearing or edentulous area of the jaws. These lesions are usually asymptomatic; therefore, they are frequently diagnosed incidentally during routine radiographic examinations. Lesions are usually benign, show limited growth, and do not require further surgical intervention, but periodic follow-up is recommended because occasionally, this type of dysplasia progresses into florid osseous dysplasia and simple bone cysts are formed. A 24-year-old female patient was referred to our clinic for swelling in the left edentulous mandibular premolarmolar region and felt discomfort when she wore her prosthetics. She had no pain, tenderness or paresthesia. Clinical examination showed that the swelling in the posterior mandible that was firm, nonfluctuant and covered by normal mucosa. On panoramic radiography and computed tomography, a well defined lesion of approximately 1.5 cm in diameter of mixed density was observed. The swelling increased slightly in size over 2 years making it difficult to use prosthetics and, therefore, the lesion was totally excised under local anesthesia, and surgical specimens were submitted for histopathological examination. The histopathological diagnosis was focal cemento-osseous dysplasia. In the present case, because of the increasing size of the swelling making it difficult to use prosthetics, young age of the patient and localization of the lesion, in the initial examination, cemento-ossifying fibroma was suspected, and the lesion was excised surgically; the histopathological diagnosis confirmed it as focal cemento-osseous dysplasia. We present a case of expansive focal cemento-osseous dysplasia. Differential diagnosis is essential because ossifying fibroma is a real neoplastic entity.

Meckel's diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1-3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult. We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel's diverticulum causing intussusception. Intestinal obstruction in patients with Meckel's diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture. Consideration of Meckel's diverticulum although a rare diagnosis is imperative and this case raises the question "should surgeons routinely examine the bowel for Meckel's diverticulum at laparoscopy?"

The diagnosis of vitamin A intoxification may be difficult at the time of initial presentation. The radionuclide bone scan in cases of vitamin A toxicity may serve as a more sensitive indicator of the presence of this disease than radiographs in the initial evaluation and follow-up of patients with skeletal involvement. This is achieved at a lower radiation dose to the patient. The authors present a case in which bone scintigraphy played a crucial role in the early identification of this disorder. The radionuclide examination was the first method that indicated the presence of this disorder, significantly before changes demonstrablemore » on conventional radiography. The clinical and scintigraphic appearance of this process should be recognized to allow identification of hypervitaminosis A before the clinical symptoms become severe or permanent skeletal deformities result.« less

Prosthetic graft infection after vascular reconstruction is a rare but serious complication. We report a case of infection occurring late after implantation of an iliofemoral prosthetic vascular graft. The Staphylococcus aureus infection was revealed by vascular purpura localized on the right leg 7 years after implantation of a vascular prosthesis. This case illustrates an uncommonly late clinical manifestation presenting as an acute infection 7 years after the primary operation. In this situation, the presentation differs from early infection, which generally occurs within the first four postoperative months. Diagnosis and treatment remain a difficult challenge because prosthetic graft infection is a potentially life-threatening complication. Morbidity and mortality rates are high. Here we detail specific aspects of the clinical and radiological presentation. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Summary Background Paragangliomas are benign neuroendocrine tumors derived from the glomus cells of the vegetative nervous system. Typically, they are located in the region of the jugular bulb and middle ear. The optimal management is controversial and can include surgical excision, stereotactic radiosurgery and embolization. Case Report We report the endovascular approach to three patients harboring glomus jugulare paragangliomas. In all cases incomplete occlusion of the lesions was achieved and recanalization in the follow-up period was revealed. Two patients presented no clinical improvement and the remaining one experienced a transient withdrawal of tinnitus. Conclusions It is technically difficult to achieve complete obliteration of glomus jugulare tumors with the use of embolization and the subtotal occlusion poses a high risk of revascularization and is not beneficial in terms of alleviating clinical symptoms.

Functional tremor.

Schwingenschuh, P; Deuschl, G

2016-01-01

Functional tremor is the commonest reported functional movement disorder. A confident clinical diagnosis of functional tremor is often possible based on the following "positive" criteria: a sudden tremor onset, unusual disease course, often with fluctuations or remissions, distractibility of the tremor if attention is removed from the affected body part, tremor entrainment, tremor variability, and a coactivation sign. Many patients show excessive exhaustion during examination. Other somatizations may be revealed in the medical history and patients may show additional functional neurologic symptoms and signs. In cases where the clinical diagnosis remains challenging, providing a "laboratory-supported" level of certainty aids an early positive diagnosis. In rare cases, in which the distinction from Parkinson's disease is difficult, dopamine transporter single-photon emission computed tomography (DAT-SPECT) can be indicated. © 2016 Elsevier B.V.

Clinical decision making in a high-risk primary care environment: a qualitative study in the UK.

2012-01-01

Examine clinical reasoning and decision making in an out of hours (OOH) primary care setting to gain insights into how general practitioners (GPs) make clinical decisions and manage risk in this environment. Semi-structured interviews using open-ended questions. A 2-month qualitative interview study conducted in Oxfordshire, UK. 21 GPs working in OOH primary care. The most powerful themes to emerge related to dealing with urgent potentially high-risk cases, keeping patients safe and responding to their needs, while trying to keep patients out of hospital and the concept of 'fire fighting'. There were a number of well-defined characteristics that GPs reported making presentations easy or difficult to deal with. Severely ill patients were straightforward, while the older people, with complex multisystem diseases, were often difficult. GPs stopped collecting clinical information and came to clinical decisions when high-risk disease and severe illness requiring hospital attention has been excluded; they had responded directly to the patient's needs and there was a reliable safety net in place. Learning points that GPs identified as important for trainees in the OOH setting included the importance of developing rapport in spite of time pressures, learning to deal with uncertainty and learning about common presentations with a focus on critical cues to exclude severe illness. The findings support suggestions that improvements in primary care OOH could be achieved by including automated and regular timely feedback system for GPs and individual peer and expert clinician support for GPs with regular meetings to discuss recent cases. In addition, trainee support and mentoring to focus on clinical skills, knowledge and risk management issues specific to OOH is currently required. Investigating the stopping rules used for diagnostic closure may provide new insights into the root causes of clinical error in such a high-risk setting.

Clinical decision support is a powerful tool for improving healthcare quality and patient safety. However, developing a comprehensive package of decision support interventions is costly and difficult. If used well, Web 2.0 methods may make it easier and less costly to develop decision support. Web 2.0 is characterized by online communities, open sharing, interactivity and collaboration. Although most previous attempts at sharing clinical decision support content have worked outside of the Web 2.0 framework, several initiatives are beginning to use Web 2.0 to share and collaborate on decision support content. We present case studies of three efforts: the Clinfowiki, a world-accessible wiki for developing decision support content; Partners Healthcare eRooms, web-based tools for developing decision support within a single organization; and Epic Systems Corporation's Community Library, a repository for sharing decision support content for customers of a single clinical system vendor. We evaluate the potential of Web 2.0 technologies to enable collaborative development and sharing of clinical decision support systems through the lens of three case studies; analyzing technical, legal and organizational issues for developers, consumers and organizers of clinical decision support content in Web 2.0. We believe the case for Web 2.0 as a tool for collaborating on clinical decision support content appears strong, particularly for collaborative content development within an organization.

Descriptions of uncommon diseases with intracranial imaging abnormalities are often difficult to find in the radiology literature. We hypothesized that reported imaging findings of such conditions in the recent literature were more frequent in clinical compared with radiology journals. PubMed searches from December 1, 2007 to December 1, 2012 were performed for 5 uncommon CNS diseases with intracranial imaging manifestations: 1) Susac syndrome; 2) amyloid β-related angiitis; 3) Parry-Romberg syndrome/en coup de sabre; 4) transient lesion of the splenium of the corpus callosum; and 5) reversible cerebral vasoconstriction syndrome. Articles were classified as a case report, case series, or original research. Journals were categorized as radiology or clinical. The 1- and 5-year Impact Factors of the journals were recorded. Two hundred two articles were identified for the 5 diseases, including 151 (74%) case reports, 26 case series (13%), and 25 original research articles (13%); 179 (89%) were published in nonradiology journals, compared with 23 (11%) in radiology journals. There was no significant difference between the mean 1- and 5-year Impact Factors of the radiology and clinical journals. Recent reports of the selected uncommon diseases with intracranial manifestations are more frequent in clinical journals when compared with dedicated radiology publications. Most publications are case reports. Radiologists should review both radiology and clinical journals when reviewing imaging features of uncommon diseases affecting the brain. Lack of reporting on such disease in the radiology literature may have significant practice, educational, and research implications for the radiology community.

This study was conducted to develop case-based decision support software to improve glucose control in patients with type 1 diabetes mellitus (T1DM) on insulin pump therapy. While the benefits of good glucose control are well known, achieving and maintaining good glucose control remains a difficult task. Case-based decision support software may assist by recalling past problems in glucose control and their associated therapeutic adjustments. Twenty patients with T1DM on insulin pumps were enrolled in a 6-week study. Subjects performed self-glucose monitoring and provided daily logs via the Internet, tracking insulin dosages, work, sleep, exercise, meals, stress, illness, menstrual cycles, infusion set changes, pump problems, hypoglycemic episodes, and other events. Subjects wore a continuous glucose monitoring system at weeks 1, 3, and 6. Clinical data were interpreted by physicians, who explained the relationship between life events and observed glucose patterns as well as treatment rationales to knowledge engineers. Knowledge engineers built a prototypical system that contained cases of problems in glucose control together with their associated solutions. Twelve patients completed the study. Fifty cases of clinical problems and solutions were developed and stored in a case base. The prototypical system detected 12 distinct types of clinical problems. It displayed the stored problems that are most similar to the problems detected, and offered learned solutions as decision support to the physician. This software can screen large volumes of clinical data and glucose levels from patients with T1DM, identify clinical problems, and offer solutions. It has potential application in managing all forms of diabetes.

The identification of feline herpesvirus (FHV) infected cheetahs (Acinonyx jubatus) and characterization of shedding episodes is difficult due to nonspecific clinical signs and limitations of diagnostic tests. The goals of this study were to develop a case definition for clinical FHV and describe the distribution of signs. Medical records from six different zoologic institutions were reviewed to identify cheetahs with diagnostic test results confirming FHV. Published literature, expert opinion, and results of a multiple correspondence analysis (MCA) were used to develop a clinical case definition based on 69 episodes in FHV laboratory confirmed (LC) cheetahs. Four groups of signs were identified in the MCA: general ocular signs, serious ocular lesions, respiratory disease, and cutaneous lesions. Ocular disease occurred with respiratory signs alone, with skin lesions alone, and with both respiratory signs and skin lesions. Groups that did not occur together were respiratory signs and skin lesions. The resulting case definition included 1) LC cheetahs; and 2) clinically compatible (CC) cheetahs that exhibited a minimum of 7 day's duration of the clinical sign groupings identified in the MCA or the presence of corneal ulcers or keratitis that occurred alone or in concert with other ocular signs and skin lesions. Exclusion criteria were applied. Application of the case definition to the study population identified an additional 78 clinical episodes, which represented 58 CC cheetahs. In total, 28.8% (93/322) of the population was identified as LC or CC. The distribution of identified clinical signs was similar across LC and CC cheetahs. Corneal ulcers and/or keratitis, and skin lesions were more frequently reported in severe episodes; in mild episodes, there were significantly more cheetahs with ocular-only or respiratory-only disease. Our results provide a better understanding of the clinical presentation of FHV, while presenting a standardized case definition that can both contribute to earlier diagnoses and be used for population-level studies.

Background/Aim: Adenocarcinoma is one of the most common malignant tumors of the small intestine complicating Crohn’s disease. However, the coexistence of both conditions with diverticulosis of small bowel in young age makes this coincidence rare and clinical diagnosis very difficult. Case Report: We report a case of a woman admitted to our Department with acute abdominal pain and fever. The surgical and histological investigation, revealed a rare coexistence that has never been mentioned in the published medical literature. Conclusion: Ileal diverticulosis is not frequent and often asymptomatic as well as adenocarcinoma of the small bowel. In this case, those diseases along with Crohn’s disease led the patient to acute symptoms. PMID:29275319

Lymphoepithelioma-like carcinoma (LELC) is a rare type of neoplasm in which only twenty cases have been reported in the breast. This type of tumor can be difficult to distinguish from other breast tumors particularly medullary carcinoma and lymphoma in the breast. We present a case of LELC of the breast presenting as an abscess along with a review of the literature. This is the 21(st) reported case of LELC of the breast and the first case to present as an abscess. Her clinical picture could have been mistaken for other infectious or inflammatory diseases. Given the potential for favorable outcome, early detection and general knowledge of this neoplasm are essential to expedite treatment for this rare tumor type.

Beyond PubMed: Searching the “Grey Literature” for Clinical Trial Results

PubMed Central

2014-01-01

Clinical trial results have been traditionally communicated through the publication of scholarly reports and reviews in biomedical journals. However, this dissemination of information can be delayed or incomplete, making it difficult to appraise new treatments, or in the case of missing data, evaluate older interventions. Going beyond the routine search of PubMed, it is possible to discover additional information in the “grey literature.” Examples of the grey literature include clinical trial registries, patent databases, company and industrywide repositories, regulatory agency digital archives, abstracts of paper and poster presentations on meeting/congress websites, industry investor reports and press releases, and institutional and personal websites.

2018-06-01

Abdominal aortic aneurysm (AAA) associated with periaortic malignant lymphoma is difficult to differentiate from aneurysmal rupture because of similarities in their clinical presentation and appearance on computed tomography images. We here report a case of AAA associated with periaortic malignant lymphoma diagnosed preoperatively with an absence of typical symptoms, showing that AAA in periaortic malignant lymphoma can present without any clinical correlates. Magnetic resonance imaging was used to confirm the diagnosis. The patient was treated by endovascular repair, which may be safer and more effective than open surgery for AAA associated with malignant lymphoma because of the tight adhesion between the aneurysm and the lymphoid tissue.

A novel mutation of CLCNKB in a Korean patient of mixed phenotype of Bartter-Gitelman syndrome.

2016-11-01

Bartter syndrome (BS) is an inherited renal tubular disorder characterized by low or normal blood pressure, hypokalemic metabolic alkalosis, and hyperreninemic hyperaldosteronism. Type III BS is caused by loss-of-function mutations in CLCNKB encoding basolateral ClC-Kb. The clinical phenotype of patients with CLCNKB mutations has been known to be highly variable, and cases that are difficult to categorize as type III BS or other hereditary tubulopathies, such as Gitelman syndrome, have been rarely reported. We report a case of a 10-year-old Korean boy with atypical clinical findings caused by a novel CLCNKB mutation. The boy showed intermittent muscle cramps with laboratory findings of hypokalemia, severe hypomagnesemia, and nephrocalcinosis. These findings were not fully compatible with those observed in cases of BS or Gitelman syndrome. The CLCNKB mutation analysis revealed a heterozygous c.139G>A transition in exon 13 [p.Gly(GGG)465Glu(GAG)]. This change is not a known mutation; however, the clinical findings and in silico prediction results indicated that it is the underlying cause of his presentation.

[External stability of the elbow after surgical treatment of epicondylitis. Presentation of a case].

PubMed

Llop-Corbacho, A; Romero-Ruiz, J; Denia-Alarcón, N

2014-01-01

Elbow instability is a difficult to diagnose condition in certain cases, and could lead to some problems that limit daily functioning, such as joint blocks, bumps, projections, muscle weakness, and persistent pain. A case is presented of a patient with a clinical picture of epicondylitis, with a previous history of a fall on the affected arm. As there was no improvement after performing conventional non-aggressive treatment, surgery was performed on the affected tendon. The outcome of this was persistent pain and clinical instability of the elbow that ended up requiring surgery to reconstruct the ligament over the external complex. In follow-up 6 months after the operation, the clinical instability had disappeared, but there was still external discomfort and a 30° extension deficit. When faced with a picture of epicondylitis with a previous injury that does not respond to conventional therapies, it is important to take into account the possibility of an underlying elbow instability, ruling this out with a correct physical examination and, where necessary, with the appropriate complementary tests.

2017-01-01

Patients who display disruptive behaviours in the clinical encounter (the so-called 'difficult patients') may negatively affect doctors' diagnostic reasoning, thereby causing diagnostic errors. The present study aimed at investigating the mechanisms underlying the negative influence of difficult patients' behaviours on doctors' diagnostic performance. A randomised experiment with 74 internal medicine residents. Doctors diagnosed eight written clinical vignettes that were exactly the same except for the patients' behaviours (either difficult or neutral). Each participant diagnosed half of the vignettes in a difficult patient version and the other half in a neutral version in a counterbalanced design. After diagnosing each vignette, participants were asked to recall the patient's clinical findings and behaviours. Main measurements were: diagnostic accuracy scores; time spent on diagnosis, and amount of information recalled from patients' clinical findings and behaviours. Mean diagnostic accuracy scores (range 0-1) were significantly lower for difficult than neutral patients' vignettes (0.41 vs 0.51; p<0.01). Time spent on diagnosing was similar. Participants recalled fewer clinical findings (mean=29.82% vs mean=32.52%; p<0.001) and more behaviours (mean=25.51% vs mean=17.89%; p<0.001) from difficult than from neutral patients. Difficult patients' behaviours induce doctors to make diagnostic errors, apparently because doctors spend part of their mental resources on dealing with the difficult patients' behaviours, impeding adequate processing of clinical findings. Efforts should be made to increase doctors' awareness of the potential negative influence of difficult patients' behaviours on diagnostic decisions and their ability to counteract such influence.

Congenital esophageal stenosis (CES) is a rare congenital abnormality that is difficult to diagnose and often masquerades as other types of structural esophageal disease. We report three cases of CES with different presenting symptoms. We advocate for balloon dilation as the preferred first approach to therapeutic intervention. CES is an important clinical entity in the evaluation of pediatric esophageal disorders and should be suspected in young infants with dysphagia.

Potential Usefulness of the Kampo Medicine Yokukansan, Containing Uncaria Hook, for Paediatric Emotional and Behavioural Disorders: A Case Series

PubMed Central

2013-01-01

Background. Paediatric emotional and behavioural disorders (EBD) are relatively common diseases. Although nonpharmacologic and pharmacologic treatments are utilized in these cases, it is sometimes difficult to manage the symptoms of EBD. Historically, Uncaria hook has been used for treating nighttime crying and convulsions in children. Recent clinical studies have demonstrated that the Kampo medicine Yokukansan (YKS), which contains Uncaria hook, is efficacious for behaviour disorders in Alzheimer's disease patients. Herein, we investigated the clinical efficacy and safety of YKS in a series of cases with paediatric EBD. Patients and Methods. We retrospectively reviewed all paediatric patients who sought Japanese Kampo therapy at our outpatient clinics between April 1, 2012, and April 30, 2013; we selected patients who were diagnosed with paediatric EBD and were treated with YKS. Results. After screening all candidates, 3 patients were eligible for this analysis. Their average age was 11.6 years (range 10–13 years). All 3 patients responded very well to YKS within 1 month. No drug-related adverse events were observed during the course of YKS treatment. Conclusion. Yokukansan may be efficacious for paediatric EBD. We believe these results warrant further evaluation of the clinical efficacy and safety of Yokukansan for paediatric EBD in a carefully designed, double-blind, randomized clinical study.

Ovarian fibromas are the most common benign solid ovarian tumors, which are often difficult to diagnose preoperatively. Ovarian fibromas, especially in bilateral cases, may be cases of Gorlin-Goltz syndrome (GGS), a rare autosomal dominant disorder with predisposition to basal cell carcinomas (BCCs) and other various benign and malignant tumors. This case report describes a 25 year-old female with GGS, bilateral ovarian fibroma, endometriosis and septated uterus, which was referred to the Gynecology Clinic of Rasoul-e-Akram Hospital in October 2016. This patient had facial asymmetry due to recurrent odontogenic keratocysts. In young cases of ovarian fibromas as reported here, conservative surgical management can preserve ovarian function and fertility. These patients must be followed up by a multidisciplinary team and submitted to periodic tests. PMID:29334213

Diagnostic pitfalls in the assessment of congenital hypopituitarism.

2014-12-01

The diagnosis of congenital hypopituitarism is difficult and often delayed because its symptoms are nonspecific. To describe the different clinical presentations of children with congenital hypopituitarism to reduce the time for diagnosis and to begin a precocious and appropriate treatment. We analyzed a cohort of five children with congenital hypopituitarism, describing their clinical, biochemical and radiological characteristics from the birth to diagnosis. As first sign of the disease, all of five patients presented a neonatal hypoglycemia, associated in four cases with jaundice. In all these four cases, the clinicians hypothesized a metabolic disease delaying the diagnosis, which was performed in only two cases within the neonatal period. In the other three cases, the diagnosis was formulated at 2, 5 and 8 years of life because there was severe and precocious growth impairment. It is important to suspect congenital hypopituitarism in the presence of persistent neonatal hypoglycemia associated with jaundice and of a precocious and severe reduction of the growth velocity in childhood. In all these cases, it is necessary to undertake a hypothalamic-pituitary magnetic resonance imaging scan as soon as possible, and to start appropriate treatment.

An unexpected tetanus case.

1 million cases of tetanus are estimated to occur worldwide each year, with more than 200 000 deaths. Tetanus is a life-threatening but preventable disease caused by a toxin produced by Clostridium tetani-a Gram-positive bacillus found in high concentrations in soil and animal excrement. Tetanus is almost completely preventable by active immunisation, but very rarely unexpected cases can occur in individuals who have been previously vaccinated. We report a case of generalised tetanus in a 22-year-old woman that arose despite the protective antitoxin antibody in her serum. The patient received all her vaccinations in the USA; her last vaccination was 6 years ago. The case was unusual because the patient had received all standard vaccinations, had no defined port of entry at disease onset, and had symptoms lasting for 6 months. Tetanus can present with unusual clinical forms; therefore, the diagnosis and management of this rare but difficult disease should be updated. In this Grand Round, we review the clinical features, epidemiology, treatment, and prognosis of C tetani infections. Copyright © 2016 Elsevier Ltd. All rights reserved.

Influencing clinicians and healthcare managers: can ROC be more persuasive?

Taylor-Phillips, S.; Wallis, M. G.; Duncan, A.; Gale, A. G.

Receiver Operating Characteristic analysis provides a reliable and cost effective performance measurement tool, without using full clinical trials. However, when ROC analysis shows that performance is statistically superior in one condition than another it is difficult to relate this result to effects in practice, or even to determine whether it is clinically significant. In this paper we present two concurrent analyses: using ROC methods alongside single threshold recall rate data, and suggest that reporting both provides complimentary data. Four mammographers read 160 difficult cases (41% malignant) twice, with and without prior mammograms. Lesion location and probability of malignancy was reported for each case and analyzed using JAFROC. Concurrently each participant chose recall or return to screen for each case. JAFROC analysis showed that the presence of prior mammograms improved performance (p<.05). Single threshold data showed a trend towards a 26% increase in the number of false positive recalls without prior mammograms (p=.056). If this trend were present throughout the NHS Breast Screening Programme then discarding prior mammograms would correspond to an increase in recall rate from 4.6% to 5.3%, and 12,414 extra women recalled annually for assessment. Whilst ROC methods account for all possible thresholds of recall and have higher power, providing a single threshold example of false positive, false negative, and recall rates when reporting results could be more influential for clinicians. This paper discusses whether this is a useful additional method of presenting data, or whether it is misleading and inaccurate.

A New Classification of Endodontic-Periodontal Lesions

PubMed Central

Al-Fouzan, Khalid S.

2014-01-01

The interrelationship between periodontal and endodontic disease has always aroused confusion, queries, and controversy. Differentiating between a periodontal and an endodontic problem can be difficult. A symptomatic tooth may have pain of periodontal and/or pulpal origin. The nature of that pain is often the first clue in determining the etiology of such a problem. Radiographic and clinical evaluation can help clarify the nature of the problem. In some cases, the influence of pulpal pathology may cause the periodontal involvement and vice versa. The simultaneous existence of pulpal problems and inflammatory periodontal disease can complicate diagnosis and treatment planning. An endo-perio lesion can have a varied pathogenesis which ranges from simple to relatively complex one. The differential diagnosis of endodontic and periodontal diseases can sometimes be difficult, but it is of vital importance to make a correct diagnosis for providing the appropriate treatment. This paper aims to discuss a modified clinical classification to be considered for accurately diagnosing and treating endo-perio lesion. PMID:24829580

This study is based on 25 well documented reports of cases which responded well to treatment with Petroleum. Materia medica data were compared with results in contemporary clinical practice. Many patients had characteristic skin problems; children often had recurrent or chronic upper respiratory tract problems. The most prominent mental feature is a quiet, withdrawn or stubborn disposition. The mental symptoms may be difficult to recognise. Detailed documentation in daily practice can be helpful for preserving data of the effect of a medicine; confirmation of statements given in materia medica; improving understanding of homeopathic medicines and differentiating the indications for medicines.

Metachromatic leukodystrophy (MLD) is a rare demyelinating disease (prevalence 1:40 000), also called arylsulfatase A deficiency (ARS-A), which may present with neurological and psychiatric symptoms. Clinical assessment may be difficult, due to unspecific signs and symptoms. A case is presented of a 16 year-old female patient seen in psychiatry due to behavioural changes, psychosis, and with impaired overall performance. She was initially diagnosed with schizophrenia, but the Nuclear Magnetic Resonance (NMR) scan and laboratory tests lead to the diagnosis of MLD. Copyright © 2016 Asociación Colombiana de Psiquiatría.

Rocky Mountain spotted fever (RMSF) is an acute febrile illness caused by infection with Ricketsia Rickettsii, characterized by the presence of petechial rash. Even though the etiology, clinical characteristics and availability of effective antibiotics are known, RMSF related deaths have a prevalence of 4%. In its early stages RMFS can resemble many others infectious conditions and the diagnosis can be difficult. The present paper reports two patients with RMSF; these cases underscore the importance of prompt diagnosis and appropriate antimicrobial therapy, and consider RMSF as a differential diagnosis in any patient who develops fever and rash in an endemic area.

Nineteen review articles and case reports were identified and reviewed through August 1996 in Index Medicus, MEDLINE (English and foreign language), conference abstracts, and bibliographies from major articles, textbooks and reviews, to review Munchausen's syndrome in obstetrics and gynecology. In these 19 articles, 30 reported cases of the syndrome were identified in obstetric and gynecological patients. This survey found that the presentation varied, diagnosis was difficult, treatment was unclear, and the economic burden was enormous. Increasingly, this syndrome is becoming an important clinical entity in the specialty, and requires a high index of suspicion to improve detection and optimize treatment.

This rare condition occurs preferentially in immunodeficient subjects. Because of its clinical polymorphism, its diagnosis is difficult and is often not made until complications develop. Endonasal surgery with anatomopathological and mycological examination is both a diagnostic and therapeutic procedure. It must be performed early, to avoid functional or even life-threatening complications.

The current report presents a case of an omental fibromatosis discovered incidentally in a 46-year-old woman with no particular medical history and few symptoms. A surgical biopsy was performed initially, and microscopic examination revealed myofibroblastic proliferation. After additional immunohistochemical and molecular analyses, omental fibromatosis was diagnosed. Omental fibromatosis, also called intra-abdominal desmoid, is a rare and benign tumour but can be locally aggressive. Majority of cases are asymptomatic, and difficult to diagnose based on clinical presentation and radiological investigation. Final diagnosis is usually made on histopathology and immunohistochemistry studies. Surgical wide excision is currently the treatment of choice.

2018-06-01

Superimposition of digital models may be performed to assess tooth movement in three dimensions. Detailed analysis of changes in tooth position after treatment may be achieved by this method. This article describes the method of superimposing digital models with a clinical case. It emphasizes the difficult procedure of superimposing 3D models in the lower arch. A methodology for superimposing mandibular models acquired with a structured light 3D scanner is discussed. Superimposition of digital models is useful to analyse tooth movement in the three planes of space, presenting advantages over the method of cephalogram superimposition. It seems feasible to superimpose digital models in the lower arch in patients without growth by using a coordinate system based on the palatal rugae and occlusion. The described method aims to advance the difficult procedure of superimposing digital models in the mandibular arch, but further research is nonetheless required in this field. Copyright © 2018 CEO.

Fleischman, a Senior Vice President of the New York Academy of Medicine (NYAM), with representation from clinical medicine, biomedical ethics, law, and the clergy, developed a position on the difficult and contentious issue of physician-assisted suicide. After substantial debate, the Board of Trustees of NYAM authorized a letter from the President of the Academy to the Justices of the United States Supreme Court and to the attorneys on both sides of the cases about to be argued before the Court. The text of that letter, which summarizes the views of the New York Academy of Medicine, is reproduced here.

Clinical presentations of pathologically confirmed corticobasal degeneration (CBD) vary, and the heterogeneity makes its clinical diagnosis difficult, especially when a patient lacks any motor disturbance in the early stage. We compared clinical and pathological features of four pathologically confirmed CBD cases that initially developed non-motor symptoms, including behavioural and psychiatric symptoms but without motor disturbance (CBD-NM), and five CBD cases that initially developed parkinsonism and/or falls (CBD-M). The age range at death for the CBD-NM and CBD-M subjects (58-85 years vs 45-67 years) and the range of disease duration (2-18 years vs 2-6 years) did not significantly differ between the groups. Prominent symptoms in the early stage of CBD-NM cases included self-centred behaviours such as frontotemporal dementia (n = 1), apathy with and without auditory hallucination (n = 2), and aggressive behaviours with delusion and visual hallucination (n = 1). Among the four CBD-NM cases, only one developed asymmetric motor disturbance, and two could walk without support throughout the course. Final clinical diagnoses of the CBD-NM cases were frontotemporal dementia (n = 2), senile psychosis with delirium (n = 1), and schizophrenia (n = 1). Neuronal loss was significantly less severe in the subthalamic nucleus and substantia nigra in the CBD-NM cases than in the CBD-M cases. The severity of tau pathology in all regions examined was comparable in the two groups. CBD cases that initially develop psychiatric and behavioural changes without motor symptoms may have less severe degenerative changes in the subthalamic nucleus and substantia nigra, and some CBD cases can lack motor disturbance not only in the early stage but also in the last stage of the course. © 2014 The Authors.

Schnabel, Ronny M.; Linssen, Catharina F.; Guion, Nele; van Mook, Walther N.; Bergmans, Dennis C.

2014-01-01

It has been questioned if Candida pneumonia exists as a clinical entity. Only histopathology can establish the definite diagnosis. Less invasive diagnostic strategies lack specificity and have been insufficiently validated. Scarcity of this pathomechanism and nonspecific clinical presentation make validation and the development of a clinical algorithm difficult. In the present study, we analyze whether Candida pneumonia exists in our critical care population. We used a bronchoalveolar lavage (BAL) specimen database that we have built in a structural diagnostic approach to ventilator-associated pneumonia for more than a decade consisting of 832 samples. Microbiological data were linked to clinical information and available autopsy data. We searched for critically ill patients with respiratory failure with no other microbiological or clinical explanation than exclusive presence of Candida species in BAL fluid. Five cases could be identified with Candida as the likely cause of pneumonia. PMID:25734099

We report two cases of impression material foreign body in the middle ear. The first case had been affected with chronic otitis media. The silicone flowed into the middle ear through a tympanic membrane perforation during the process of making an ear mold. About 4 years and 8 months after, the patient had severe vertigo and deafness. We found bone erosion of the prominence of the lateral semicircular canal and diagnosed labyrinthitis caused by silicone impression material. In the second case silicone flowed into the canal wall down mastoid cavity. Both cases required surgery to remove the foreign body. The clinical courses in such cases are variable and timing of surgery is sometimes difficult. In addition to reporting these two cases, we present here a review of the literature regarding impression material foreign bodies. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome (NBCCS) comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies, calcifications of the falx cerebri etc. The diagnosis is made according to clinical criteria (Kimonis Criteria) and genetic ones. We studied one family where father and then his sun resulted affected by each syndrome. Gorlin-Goltz syndrome is a rare disease diagnosed according to clinical criteria sometimes difficult to integrate. The family case we presented shows how you can get diagnosis even in older age and after numerous surgeries. Patients should be given special attention and therefore should be monitorized and need multidisciplinary treatments continued in time, even a trivial change of signs and symptoms may be an important indicator of a precipitating event which puts the patient's life under threat.

Franco, Alvaro; Ramírez, Luis

2016-01-01

In the review of the current literature, the main causing factors of the related conditions with child sexual abuse are the ethical dilemmas and legal implications. A review was conducted on the classic literature on this topic. In this articlesome difficult paradigmatic cases are presented in which the hypothetical dilemmas were solved. The main characteristics of child sexual abuse enable us to have a better argument to address these situations. Taking into account the literature reviewed and predictable courses of action, it is concluded that it is important to take into account each individual each case and its circumstances, and that prudence and clinical objectivity, as well as knowledge of the law, become essential requirements for proper action.

Pauli, Wojciech; Zarzycki, Artur; Krzyształowski, Adam; Walecka, Anna

2013-01-01

Summary Background: MELAS syndrome (mitochondrial myopathy, encephalopathy, lactic acidosis, stroke-like episodes) is a rare, multisystem disorder which belongs to a group of mitochondrial metabolic diseases. As other diseases in this group, it is inherited in the maternal line. Case Report: In this report, we discussed a case of a 10-year-old girl with clinical and radiological picture of MELAS syndrome. We would like to describe characteristic radiological features of MELAS syndrome in CT, MRI and MR spectroscopy of the brain and differential diagnosis. Conclusions: The rarity of this disorder and the complexity of its clinical presentation make MELAS patients among the most difficult to diagnose. Brain imaging studies require a wide differential diagnosis, primarily to distinguish between MELAS and ischemic stroke. Particularly helpful are the MRI and MR spectroscopy techniques.

Keratosis obturans (KO) and external auditory canal cholesteatoma (EACC) have been considered separate entities. While the disorders are distinct, they share many overlapping characteristics, making a correct diagnosis difficult. In the present study, we compared their clinical characteristics and radiological features to clarify the diagnostic criteria. Retrospective case series. Academic medical center. The clinical data of 23 cases of EACC and KO were retrospectively reviewed. The following clinical characteristics were compared between the 2 groups: sex, age, onset of symptoms, follow-up period, audiometric results, and imaging findings on temporal bone computed tomography including bilaterality, location, and the presence of extension to adjacent tissue. The mean age of the EACC group was significantly older than that of the KO group. All of the cases of EACC occurred unilaterally, and bilateral occurrences of KO were observed in 4 of 9 cases. All of the lesions in the KO group were circumferential, and no lesion in the EACC group invaded the superior canal wall. No significant differences in symptoms, such as acute otalgia, otorrhea, and hearing loss, were noted between the 2 groups. The incidence of conductive hearing impairment more than 10 dB was higher in the KO group than in the EACC group. Thus, KO and EACC are 2 distinct disease entities that share common features in clinical characteristics except for predominant age and bilaterality. Conservative treatment with meticulous cleaning of the lesion was successful in most cases with a long-term follow-up. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

To study the clinical and laboratory characteristics of chronic active Epstein-Barr virus (EBV) infection (CAEBV) in children and to provide a basis for the diagnosis and treatment of CAEBV. The clinical data of 13 children with CAEBV, as well as 15 cases of acute EBV infection (AEBV) as controls, were analyzed, including clinical manifestations, EBV antibodies, EBV DNA, and peripheral blood lymphocyte subsets. Both groups of patients had infectious mononucleosis-like symptoms such as fever, hepatomegaly, splenomegaly, and lymphadenectasis, but CAEBV patients had a longer course of disease and continuous and recurrent symptoms. Compared with the AEBV group, the CAEBV group had a significantly higher EBV DNA load in peripheral blood (P<0.05), a significantly higher VCA-IgG titer (P<0.05), and significantly lower numbers of white blood cells, lymphocytes, B cells, total T cells, CD4+ T cells, and CD8+ T cells in peripheral blood (P<0.05). Among 13 CAEBV patients followed up, 8 cases died, 2 cases showed an improvement, 2 cases had a recurrence, and 1 case was lost to follow-up after being transferred to another hospital. All the AEBV patients were cured and had no recurrence during the one-year follow-up. The clinical manifestations of CAEBV vary in children. It is difficult to distinguish CAEBV from AEBV early. More attention should be paid to CAEBV because of its severe complications, poor prognosis, and high mortality. Measurement of EBV DNA load, VCA-IgG titer, and lymphocyte subsets in peripheral blood may be helpful in the diagnosis and differential diagnosis of CAEBV.

[Monogenic and syndromic symptoms of morbid obesity. Rare but important].

PubMed

Wiegand, S; Krude, H

2015-02-01

Monogenic and syndromic obesity are rare diseases with variable manifestation. Therefore diagnosis is difficult and often delayed. The purpose of this work was to develop a clinical diagnostic algorithm for earlier diagnosis. Available publications for clinical symptoms and molecular defects of monogenic and syndromic obesity cases were evaluated. Monogenic and syndromic obesity can be expected in cases with early manifestation before the age of 5 years and a BMI above 40 or above the 99th percentile. Syndromic cases are mostly associated with a low IQ and dwarfism. Monogenic cases are associated with additional endocrine defects. Measurement of serum leptin proves the treatable leptin deficiency. Sequencing of the melanocortin-4 receptor gene (MC4R) allows diagnosis of the most frequent monogenic form of obesity. Treatment with a melanocyte-stimulating hormone (MSH) analog can be expected in the future. Early treatment of children with Prader-Willi syndrome can prevent severe obesity. Because in some cases treatment is available, monogenic and syndromic obesity should be diagnosed early. Based on the disease symptoms, serum leptin, and MC4R sequencing, a diagnostic algorithm is proposed, which can be used to diagnose cases of morbid obesity.

The aim of this study was to determine the clinical, radiologic and endoscopic characteristics of adults with tracheobronchial foreign bodies (FB), and to review the role of fiberoptic bronchoscopy in extracting them. We reviewed the case histories and bronchoscopic reports for all patients over 14 years of age with FB treated between 1976 and 1995. Fifty-nine FB were removed from 56 patients; 68% were male and 48% were over 60 years of age. The most common clinical presentations were symptoms of respiratory infection and acute choking. In only in 28% could a risk factor for aspiration be identified. The X-ray was non specific and in 37% of cases the chest film was normal. In 66% FB aspiration was an unexpected endoscopic finding. The FB was removed from the right lung in 81.3%. FB were food items in 71% of cases. Fiberoptic bronchoscopy was useful for removal in 95% of cases, with few and unimportant complications. Two cases were resolved with rigid bronchoscopy and only one patient required surgery. FB aspiration is common and diagnosis is difficult in the adult. Fiberoptic bronchoscopy resolved most aspirations in adults with no important complications. The rigid bronchoscope should be reserved for very specific cases.

Applying a previously learned concept to a novel problem is an important but difficult process called transfer. It is suggested that a commonsense analogy aids in transfer by linking novel concepts to familiar ones. How the context of practice affects transfer when learning using analogies is still unclear. This study investigated the effect of a commonsense analogy and context familiarity for transfer of physiological concepts. First year psychology students (n = 24) learned three concepts: Starling's law, Laplace's law, and laminar-turbulent flow. The control group saw standard explanations while the intervention group saw an additional commonsense analogy. The context of learning was the organ system used for two practice clinical cases which differed for all concepts. Testing consisted of 12 new clinical cases. Starling's law cases used the organ system from practice while the other concepts presented in both novel and familiar organ systems. Half of the sample repeated testing after 1 week delay. The outcome was ratings of explanations of cases on a 0-3 scale. The effect of analogy was significant (Mean = 1.24 with, 0.86 without, F(1,22) = 4.26, p < 0.05) but not after delay (means of 1.08 and 0.75 respectively, F = (1,10), p = 0.06) There was significant effect for familiar context (Same = 1.23 (Starling), different = 0.68 (Laplace) and 0.73 (laminar-turbulent flow) (F(2,44) = 5.14, p < 0.01). Laplace's law and laminar turbulent flow cases in the familiar organ system had means of 1.65 and 1.77 respectively compared to novel cases with means of 0.74 and 0.68 (F(1,22) = 35.64, p < 0.0001). Similar effects were observed after delay. There was significant decay in performance after delay for all participants (immediate = 1.17, delayed = 0.91, F = 11.9 (1,10) p < 0.01). Common analogies aid conceptual understanding necessary for transfer. Despite conceptual aids, solving transfer problems is difficult.

Human alpha-N-acetylgalactosaminidase (alpha-NAGA) deficiency: no association with neuroaxonal dystrophy?

Two new individuals with alpha-NAGA deficiency are presented. The index patient, 3 years old, has congenital cataract, slight motor retardation and secondary demyelinisation. Screening of his sibs revealed an alpha-NAGA deficiency in his 7-year-old healthy brother who had no clinical or neurological symptoms. Both sibs are homozygous for the E325K mutation, the same genotype that was found in the most severe form of alpha-NAGA deficiency presenting as infantile neuroaxonal dystrophy. Thus, at the age of 7 years the same genotype of alpha-NAGA may present as a 'non-disease' (present healthy case) and can be associated with the vegetative state (the first two patients described with alpha-NAGA deficiency). The clinical heterogeneity among the 11 known individuals with alpha-NAGA deficiency is extreme, with a 'non-disease' (two cases) and infantile neuroaxonal dystrophy (two cases) at the opposite sides of the clinical spectrum. The broad spectrum is completed by a very heterogeneous group of patients with various degrees of epilepsy/behavioural difficulties/psychomotor retardation (four patients) and a mild phenotype in adults without overt neurological manifestations who have angiokeratoma and clear vacuolisation in various cell types (three cases). These observations are difficult to reconcile with a straightforward genotype-phenotype correlation and suggest that factors or genes other than alpha-NAGA contribute to the clinical heterogeneity of the 11 patients with alpha-NAGA deficiency.

Painful legs and moving toes syndrome: a 76-patient case series.

To better characterize the clinical features, electrophysiologic features, and treatment outcomes of painful legs and moving toes (PLMT) syndrome. Large case series. Neurology outpatient clinic at a tertiary referral center, 1983-2011. All cases of PLMT seen at our institution during an 18-year period were identified using our medical record linkage system. Key demographic, clinical, imaging, and electrophysiologic features of PLMT. Treatment outcomes and long-term follow-up are also reported. Of 76 cases identified (including 50 women [66%]), the mean age at onset was 58 years (range, 24-86 years) and at neurologic evaluation was 63 years (range, 26-88 years). Pure lower limb involvement was most common (69 patients [91%]), and 44 cases (58%) were bilateral. The most frequently diagnosed causes were peripheral neuropathy (21 cases [28%]), previous trauma (8 [11%]), and radiculopathy (7 [9%]); 32 cases (42%) were cryptogenic. Electromyography consistently showed irregular 50-millisecond to 1-second bursts of normal motor unit potential firing at 2 to 200 Hz accompanying the movements. Pain occurred first in nearly all cases and was more distressing to patients than the movements. Both components were difficult to treat, with no consistent benefit from a variety of drugs and therapeutic modalities. The syndrome persisted in most patients (83%) during the mean follow-up of 4.6 years, suggesting low likelihood of spontaneous resolution. Painful legs and moving toes syndrome is a debilitating clinical syndrome, not because of the movements but rather because of the pain, which often is refractory to treatment. Segmental lower limb involvement is most common, and neurophysiologic findings support a pathophysiologic process localizing to a central generator at the spinal cord or brainstem level.

Platelet-rich plasma and plantar fasciitis.

PubMed

Monto, Raymond R

2013-12-01

Plantar fasciitis is the most common cause of heel pain and can prove difficult to treat in its most chronic and severe forms. Advanced cases of plantar fasciitis are often associated with ankle stiffness, heel spurs, and other conditions and can lead to extensive physical disability and financial loss. Most available traditional treatments, including orthoses, nonsteroidal anti-inflammatory drugs, and steroid injections have a paucity of supportive clinical evidence. More invasive treatments, ranging from corticosteroid and botulinum-A toxin injections to shockwave therapy and plantar fasciotomy, have demonstrated varying clinical success in severe cases but carry the potential for serious complication and permanent disability. Platelet-rich plasma has recently been demonstrated to be helpful in managing chronic severe tendinopathies when other techniques have failed. This review examines the pathophysiology, diagnostic options, nonoperative treatment modalities, and surgical options currently used for plantar fasciitis. It also focuses on the clinical rationale and available evidence for using autologous platelet-rich plasma to treat severe refractory chronic plantar fasciitis.

A total of 678 cases of soft chancre were treated in one hospital between 1973 and 1979. The majority of the patients were males (97 p. cent), and most of them came originally from Maghreb or Black Africa. Contamination was from prostitution (61 p. cent) or chance acquaintances (29 p. cent). The genital ulceration was often clinically atypical, frequently syphiloid; pain was present in only 59 p. cent of cases, and adenopathy, noted in 63 p. cent of patients, had the appearance of an inflammatory bubo in only 23 p. cent. The present high frequency of soft chancres, and their misleading clinical characteristics, makes it sometimes difficult to establish the clinical differential diagnosis from syphilitic chancre, but confirmation of the latter is supplied by direct examination and culture to search for Ducreys bacillus, this being indispensable for establishing the correct diagnosis. Treatment with sulfamethoxazole trimethopin or streptomycin prevents complications and cures the affection in one or two weeks.

This article provides insights and perspectives from four experienced educators about their approaches to developing, delivering, and evaluating impactful simulation learning experiences for undergraduate nurses. A case study format has been used to illustrate the commonalities and differences of where simulation has been positioned within curricula, with examples of specialized clinical domains and others with a more generic focus. The importance of pedagogy in developing and delivering simulations is highlighted in each case study. A range of learning theories appropriate for healthcare simulations are a reminder of the commonalities across theories and that no one theory can account for the engaging and impactful learning that simulation elicits. Creating meaningful and robust learning experiences through simulation can benefit students' performance in subsequent clinical practice. The ability to rehearse particular clinical scenarios, which may be difficult to otherwise achieve, assists students in anticipating likely patient trajectories and understanding how to respond to patients, relatives, and others in the healthcare team. © 2016 Sigma Theta Tau International.

Hand eczema is a frequent disease in adults. Diagnosing the cause of hand eczema is difficult due to different classifications. There is lack of evidence on hand eczema and its causes in children. A total of 389 children between 0 and 16 years were identified between 1996 and 2016, from whom 42 (10.8%) with exclusively hand eczema were selected. In all cases a standard battery of epicutaneous patch tests was performed, as well as additional batteries depending on the clinical suspicion. The clinical and epidemiological features of these children were recorded and compared against children with eczema in other locations. The 42 children with hand eczema included 25 (60.5%) girls, and 17 (40.5%) boys, with a mean age of 10.6 +- 3.9 years, and did not differ from that of children with eczema in other locations. The definitive diagnosis after patch-testing was Atopic Dermatitis in 15 cases, Allergic Contact Dermatitis in 14 patients, Endogenous Vesiculous Eczema in 6 cases, Endogenous Hyperkeratotic Eczema in 5 cases, and Irritant Contact Dermatitis in 2 cases. The most frequent allergens detected were thiomersal (9 cases), nickel (5 cases), mercury (5 cases), and cobalt (4 cases). Hand eczema is a common condition in children. The most common cause is atopic dermatitis, although cases of allergic contact dermatitis manifesting as hand eczema are not uncommon. Any child with eczema of hands in whom an allergic cause is suspected should be referred for patch- testing. Copyright © 2017. Publicado por Elsevier España, S.L.U.

Diagnosis and Managment of Maxillary Incisor with Vertical Root Fracture: A Clinical Report with Three-Year Follow-Up

2018-01-01

According to the American Association of Endodontists, “a ‘true' vertical root fracture is defined as a complete or incomplete fracture initiated from the root at any level, usually directed buccolingually.” Vertical root fracture (VRF) usually starts from an internal dentinal crack and develops over time, due to masticatory forces and occlusal loads. When they occur in teeth, those types of fractures can present difficulties in diagnosis, and there are however many clinic and radiographical signs which can guide clinicians to the existence of the fracture. Prognosis, most often, is hopeless, and differential diagnosis from other etiologies may be difficult sometimes. In this paper, we present a case of VRF diagnosed after surgical exploration; the enlarged fracture line was filled with a fluid resin. A 36-month clinical and radiological follow-up showed an asymptomatic tooth, reduction of the periodontal probing depth from 7 mm prior to treatment to 4 mm with no signs of ankylosis. In this work, the diagnosis and treatment alternatives of vertical root fracture were discussed through the presented clinical case. PMID:29552361

Like other stromal-derived gynecological tumors, a sclerosing stromal tumor of the ovary (SSTO) is a rare benign tumor that is difficult to distinguish from a malignant ovarian tumor in clinical practice. An SSTO is routinely treated with laparotomy. Here, we present two extremely rare cases of SSTO with contralateral and ipsilateral tubal pregnancies, in which laparoscopic surgery was performed to remove the tumors. After surgery, one patient (case 1) became pregnant twice within 29 months, and the other patient (case 2) did not become pregnant within 6 months postoperatively. These two cases suggest that laparoscopic management is not only useful in treating SSTO and complicating diseases, but it may also help to reduce unnecessary surgical injury to the ovary. © 2015 S.

Ovarian fibromas are the most common benign solid ovarian tumors, which are often difficult to diagnose preoperatively. Ovarian fibromas, especially in bilateral cases, may be cases of Gorlin-Goltz syndrome (GGS), a rare autosomal dominant disorder with predisposition to basal cell carcinomas (BCCs) and other various benign and malignant tumors. This case report describes a 25 year-old female with GGS, bilateral ovarian fibroma, endometriosis and septated uterus, which was referred to the Gynecology Clinic of Rasoul-e-Akram Hospital in October 2016. This patient had facial asymmetry due to recurrent odontogenic keratocysts. In young cases of ovarian fibromas as reported here, conservative surgical management can preserve ovarian function and fertility. These patients must be followed up by a multidisciplinary team and submitted to periodic tests. Copyright© by Royan Institute. All rights reserved.

Ethics rounds do not improve the handling of ethical issues by psychiatric staff.

2015-08-01

One way to support healthcare staff in handling ethically difficult situations is through ethics rounds that consist of discussions based on clinical cases and are moderated by an ethicist. Previous research indicates that the handling of ethically difficult situations in the workplace might have changed after ethics rounds. This, in turn, would mean that the "ethical climate", i.e. perceptions of how ethical issues are handled, would have changed. To investigate whether ethics rounds could improve the ethical climate perceived by staff working in psychiatry outpatient clinics. In this quasi-experimental study, six inter-professional ethics rounds led by a philosopher/ethicist were conducted at two psychiatry outpatient clinics. Changes in ethical climate were measured at these clinics as well as at two control clinics at baseline and after the intervention period using the instrument Hospital Ethical Climate Survey. Within-groups comparisons of median sum scores of ethical climate showed that no statistically significant differences were found in the intervention group before or after the intervention period. The median sum scores for ethical climate were significantly higher, both at baseline and after the intervention period (P ≤ 0.001; P = 0.046), in the intervention group. Ethics rounds in psychiatric outpatient clinics did not result in significant changes in ethical climate. Outcomes of ethics rounds might, to a higher degree, be directed towards patient-related outcomes rather than towards the staff's working environment, as the questions brought up for discussion during the ethics rounds concerned patient-related issues.

Theory of signs and statistical approach to big data in assessing the relevance of clinical biomarkers of inflammation and oxidative stress.

PubMed

Ghezzi, Pietro; Davies, Kevin; Delaney, Aidan; Floridi, Luciano

2018-03-06

Biomarkers are widely used not only as prognostic or diagnostic indicators, or as surrogate markers of disease in clinical trials, but also to formulate theories of pathogenesis. We identify two problems in the use of biomarkers in mechanistic studies. The first problem arises in the case of multifactorial diseases, where different combinations of multiple causes result in patient heterogeneity. The second problem arises when a pathogenic mediator is difficult to measure. This is the case of the oxidative stress (OS) theory of disease, where the causal components are reactive oxygen species (ROS) that have very short half-lives. In this case, it is usual to measure the traces left by the reaction of ROS with biological molecules, rather than the ROS themselves. Borrowing from the philosophical theories of signs, we look at the different facets of biomarkers and discuss their different value and meaning in multifactorial diseases and system medicine to inform their use in patient stratification in personalized medicine.

Diagnosis and treatment of clear cell hidradenocarcinoma of the scalp.

Clear cell hidradenocarcinoma (CCH) is an exceedingly rare and highly malignant tumor of the eccrine sweat glands. Its treatment is extremely difficult due to the characteristically aggressive clinical course including repeated local recurrence and uncontrollable distal metastasis coming along with a very poor prognosis. Most published case studies recommend a wide surgical excision followed by adjuvant conservative therapy, which is generally considered to be the standard treatment. Two cases of nodular CCH of the scalp either presenting as a singular primary lesion or at an already metastatic stage were analyzed retrospectively. Wide local excision of the tumor couldn't prevent the primary carcinoma from recurring and metastasizing. Both cases received various therapies but the results were unsatisfactory. Although most authors have recommended that early wide surgical excision of the tumor is a feasible therapeutic measurement, our results raise doubts on the efficacy of this treatment strategy. As alternative approaches (i.e. chemotherapy, radiotherapy) are similarly controversial, further studies and a wide exchange of clinical experiences are crucial.

Florid cemento-osseous dysplasia (FCOD) has been described as a condition that characteristically affects the jaws of middle-aged black women. Radiographically, FCOD appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. FCOD is usually asymptomatic. In severe cases, focal expansion may occur due to infection. Management of the symptomatic patient is more difficult due to the avascular nature of the lesion which contributes to susceptibility severe infection, bone sequestration, and osteomyelitis when surgery is performed. This paper presents a rare case of severe FCOD; the black woman patient was diagnosed based on clinical and radiographic findings and treated conservatively. The examination of panoramic radiographs revealed a multiple sclerotic masses with radiolucent borders, found in the mandible and maxilla which were symmetrical at presentation. The patient continuous with the follow-up. This report confirms that a diagnosis can be made with accurate clinical and radiographic assessment. The correct selection of treatment for FCOD depends on this information.

In 2009, an increased proportion of suspected dengue cases reported to the surveillance system in Puerto Rico were laboratory negative. As a result, enhanced acute febrile illness (AFI) surveillance was initiated in a tertiary care hospital. Patients with fever of unknown origin for 2–7 days duration were tested for Leptospira, enteroviruses, influenza, and dengue virus. Among the 284 enrolled patients, 31 dengue, 136 influenza, and 3 enterovirus cases were confirmed. Nearly half (48%) of the confirmed dengue cases met clinical criteria for influenza. Dengue patients were more likely than influenza patients to have hemorrhage (81% versus 26%), rash (39% versus 9%), and a positive tourniquet test (52% versus 18%). Mean platelet and white blood cell count were lower among dengue patients. Clinical diagnosis can be particularly difficult when outbreaks of other AFI occur during dengue season. A complete blood count and tourniquet test may be useful to differentiate dengue from other AFIs. PMID:23382160

Isolated cortical vein thrombosis is an uncommon condition and often difficult to diagnose, both clinically and radiologically. We report a case of a 38 years old man who presented with headache of new onset and clinical examination was unremarkable. The unenhanced brain CT did not reveal any abnormality. In view of unrelenting headache and partial seizures, we performed magnetic resonance imaging (with axial T1, T2 and gradient echo sequences, coronal FLAIR, diffusion weighted imaging as well as Gadolinium contrast-enhanced images) and magnetic resonance venography of the brain that revealed an isolated parietal cortical vein thrombosis with the rarely reported 'cord sign'. We report the clinical and radiological findings in our patient with isolated parietal cortical vein thrombosis. PMID:22470649

Objectives: Retention of basic science knowledge, as judged by National Board of Medical Examiners' (NBME) data, suffers due to lack of apparent relevance and isolation of instruction from clinical application, especially in biochemistry. However, the literature reveals no systematic process for identifying key biochemical concepts and associated clinical conditions. This study systematically identified difficult biochemical concepts and their common clinical conditions as a critical step towards enhancing relevance and retention of biochemistry.Methods: A multi-step/ multiple stakeholder process was used to: (1) identify important biochemistry concepts; (2) determine students' perceptions of concept difficulty; (3) assess biochemistry faculty, student, and clinical teaching scholars' perceived relevance of identified concepts; and (4) identify associated common clinical conditions for relevant and difficult concepts. Surveys and a modified Delphi process were used to gather data, subsequently analyzed using SPSS for Windows.Results: Sixteen key biochemical concepts were identified. Second year medical students rated 14/16 concepts as extremely difficult while fourth year students rated nine concepts as moderately to extremely difficult. On average, each teaching scholar generated common clinical conditions for 6.2 of the 16 concepts, yielding a set of seven critical concepts and associated clinical conditions.Conclusions: Key stakeholders in the instructional process struggle to identify biochemistry concepts that are critical, difficult to learn and associated with common clinical conditions. However, through a systematic process beginning with identification of concepts and associated clinical conditions, relevance of basic science instruction can be enhanced.

Although primary mediastinal large B-cell lymphoma and classic Hodgkin lymphoma of nodular sclerosis type are distinct disease, they share several clinical characteristics and biologic features. However, there are mediastinal lymphomas that not fit in either category. These types of lymphomas are recognized as mediastinal gray zone lymphomas. Gray zone lymphomas are lymphatic tumors that cannot be assigned to a defined lymphoma entity due to morphological, clinical, or genetic reasons. In this report, we present a case of a 22 year-old-Hispanic-female diagnosed with B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Hodgkin lymphoma.

Tuberculous spondylodiscitis: epidemiology, clinical features, treatment, and outcome.

2012-04-01

Tuberculous spondylodiscitis (TS) is a rare but serious clinical condition which may lead to severe deformity and early or late neurological complications. To discuss certain aspects of the approach to TSs, focusing upon epidemiology, diagnosis, and treatment outcome. For the purpose of this review, a literature search was performed using the Pubmed database through to 19th October 2011 to identify studies published in the last 20 years, concerned in epidemiological, clinical, diagnostic, and therapeutical aspects of TS in adults. Only studies drafted in English language and reporting case series of more than 20 patients have been included. TS has been reported to accounts for 1-5% of all TB cases, and for about 50% of the cases of articulo-skeletal TB infections. Despite the actual availability of more effective diagnostic tools, early recognition of TS remains difficult and a high index of suspicion is needed due to the chronic nature of the disease and its insidious and variable clinical presentation. A prompt diagnosis is required to improve long term outcome, and a microbiological confirmation is recommended to enable appropriate choice of anti-mycobacterial agents. Surgery has an important role in alleviating pain, correcting deformities and neurological impairment, and restoring function. Further studies are required to assess the appropriate duration of anti-microbial treatment, also in regarding of a combined surgical approach.

Skin-deep diagnosis: affective bias and zebra retreat complicating the diagnosis of systemic sclerosis.

PubMed

Miller, Chad S

2013-01-01

Nearly half of medical errors can be attributed to an error of clinical reasoning or decision making. It is estimated that the correct diagnosis is missed or delayed in between 5% and 14% of acute hospital admissions. Through understanding why and how physicians make these errors, it is hoped that strategies can be developed to decrease the number of these errors. In the present case, a patient presented with dyspnea, gastrointestinal symptoms and weight loss; the diagnosis was initially missed when the treating physicians took mental short cuts and used heuristics as in this case. Heuristics have an inherent bias that can lead to faulty reasoning or conclusions, especially in complex or difficult cases. Affective bias, which is the overinvolvement of emotion in clinical decision making, limited the available information for diagnosis because of the hesitancy to acquire a full history and perform a complete physical examination in this patient. Zebra retreat, another type of bias, is when a rare diagnosis figures prominently on the differential diagnosis but the physician retreats for various reasons. Zebra retreat also factored in the delayed diagnosis. Through the description of these clinical reasoning errors in an actual case, it is hoped that future errors can be prevented or inspiration for additional research in this area will develop.

Asperger Syndrome and/or Clinical High Risk of Psychosis? A Differential Diagnostic Challenge This case-study deals with the often difficult differential diagnosis of Asperger syndrome and a clinical high risk state of psychosis, in particular as indicated by attenuated psychotic symptoms, as well as with its therapeutic implications. The presented case is a 10-year old girl, who has not been diagnosed with an autism spectrum disorder before being referred to a specialized center for early detection of psychosis due to possible hallucinatory experiences and delusional ideas. We demonstrate how to perform a context-sensitive differential diagnosis to distinguish between specific interests as well as related behaviors and unusual thought content as well as perceptive abnormalities, between paranoid ideas and biased interpretations of the behaviors of others typical for autism, and between disorganized symptoms and autistic unusual communication and social behavior. The resulting dual diagnoses in our case-study formed the basis for a complex differential indication, which considered both the increased stress vulnerability associated with an increased risk for the development of psychosis as well as the rigid thinking style associated with autism. Our case-report shows that such a precise differential indication can lead to stabilization over the long-term, even in patients with dual diagnoses.

Cellulitis Secondary to Liquid Nitrogen Cryotherapy: Case Report and Literature Review.

PubMed

Huang, Christina M; Lu, Emily Y; Kirchhof, Mark G

Liquid nitrogen cryotherapy is a commonly used technique to treat a wide variety of dermatologic conditions including actinic keratoses, non-melanoma skin cancers, verrucae, and seborrheic keratoses. The risks associated with liquid nitrogen cryotherapy are important to know and discuss with patients prior to treatment. We report a case of cellulitis secondary to liquid nitrogen cryotherapy for actinic keratosis. We sought to review the literature for an estimate of secondary infection rates following cryotherapy treatment. We searched Pubmed using the terms cryotherapy and infection or cellulitis. We then looked at articles classified as clinical trials where cryotherapy was used to treat skin conditions. We then selected clinical trials that listed cellulitis or infection as an adverse event. There were no case reports, case series, or review articles detailing the risk of infection from liquid nitrogen cryotherapy. We found 8 articles classified as clinical trials on Pubmed that did list infection as an adverse event. The risk of infection from these studies varied from approximately 2% to 30%. There was a great degree of heterogeneity in treatment sites, length of treatment, and treatment targets. While it is difficult to determine the true incidence of infection from liquid nitrogen cryotherapy, clinicians should endeavor to inform patients of this potential risk.

Granular cell tumour of the neurohypophysis: an unusual cause of hypopituitarism.

Bello, Carlos Tavares; Cipriano, Patricia; Henriques, Vanessa; Duarte, João Sequeira; Marques, Conceição Canas

2018-01-01

Granular cell tumours (GCT) are rare, slow-growing, benign neoplasms that are usually located in the head and neck. They are more frequent in the female gender and typically have an asymptomatic clinical course, being diagnosed only at autopsy. Symptomatic GCT of the neurohypophysis are exceedingly rare, being less than 70 cases described so far. The authors report on a case of a 28-year-old male that presented to the Endocrinology clinic with clinical and biochemical evidence of hypogonadism. He also reported minor headaches without any major visual symptoms. Further laboratory tests confirmed hypopituitarism (hypogonadotrophic hypogonadism, central hypothyroidism and hypocortisolism) and central nervous system imaging revealed a pituitary macroadenoma. The patient underwent transcranial pituitary adenoma resection and the pathology report described a GCT of the neurohypophysis with low mitotic index. The reported case is noteworthy for the rarity of the clinicopathological entity. Symptomatic GCTs are rare CNS tumours whose cell of origin is not well defined that usually give rise to visual symptoms, headache and endocrine dysfunction.Imaging is quite unspecific and diagnosis is difficult to establish preoperatively.Surgical excision is challenging due to lesion's high vascularity and propensity to adhere to adjacent structures.The reported case is noteworthy for the rarity of the clinicopathological entity.

We present fluorodeoxy glucose positron emission tomography-computed tomography (FDG-PET/CT) findings in a case of breast carcinoma. The PET/CT findings in this case were suspicious of second primary neoplasm in the stomach. However, on endoscopic biopsy, the lesion was found to be stomach metastasis of breast carcinoma with estrogen receptor positivity. Stomach is a rare site of breast carcinoma metastasis. Our case suggests that it is difficult to distinguish a stomach metastasis of breast cancer from a primary gastric cancer on the basis of clinical and imaging features. However, this differential diagnosis must be kept in mind and it is important to make such distinction because of its implications on patient management.

Posterior rectus sheath hernia causing intermittent small bowel obstruction.

PubMed

Lenobel, Scott; Lenobel, Robert; Yu, Joseph

2014-09-01

A posterior rectus sheath hernia is an abdominal wall hernia that is rarely encountered. Owing to its rarity, it can be easily overlooked in the setting of a patient presenting with abdominal pain. We report a case of a posterior rectus sheath hernia that caused intermittent small bowel obstruction. The unusual aspects of this case are that the defect was large, measuring 6 cm in the transverse diameter, and that it contained small bowel within a large portion of the rectus sheath. Because the defect was large and affected nearly the entire posterior rectus sheath, it was difficult to discern on computed tomography until a small bowel obstruction developed. In this case, a limited awareness of this clinical entity contributed to the delay in diagnosis.

Eagle's Syndrome

Pinheiro, Thaís Gonçalves; Soares, Vítor Yamashiro Rocha; Ferreira, Denise Bastos Lage; Raymundo, Igor Teixeira; Nascimento, Luiz Augusto; Oliveira, Carlos Augusto Costa Pires de

2013-01-01

Summary Introduction: Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. Objective: To describe a case of Eagle's syndrome. Case Report: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT) of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. Final Comments: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical. PMID:25992033

Range of therapeutic metformin concentrations in clinical blood samples and comparison to a forensic case with death due to lactic acidosis.

Due to a lack of reference values for blood concentration of metformin in the literature, the forensic evaluation of metformin findings in blood samples is difficult. Interpretations with regard to the assessment of blood concentrations as well as an estimation of the ingested metformin amounts are often vague. Furthermore, post mortem evaluation of death due to lactic acidosis because of metformin is difficult since renal performance or lactate concentrations can not always reliably be determined after death. To describe a concentration range in clinical samples after chronic use of metformin, metformin serum concentrations were determined in serum samples of 95 diabetic patients receiving daily doses of 500mg-3000mg of metformin. The analyses of metformin was carried out using a validated high performance liquid chromatograph coupled to triple quadrupole mass spectrometry (LC-QQQ-MS). On average, metformin concentrations were 1846ng/mL (

What is It? Difficult to Pigeon Hole Tremor: a Clinical–Pathological Study of a Man with Jaw Tremor

PubMed Central

Louis, Elan D.; Bain, Peter G.; Hallett, Mark; Jankovic, Joseph; Vonsattel, Jean-Paul G.

2013-01-01

Background The phenomenology of tremor is broad and its classification is complicated. Furthermore, the full range of tremor phenomenology with respect to specific neurological and neurodegenerative diseases has not been fully elaborated. Case Report This right-handed man had a chief complaint of jaw tremor, which began approximately 20 years prior to death at age 101 years. He had been diagnosed with essential tremor (ET) by a local doctor. His examination at age 100 years was notable for marked jaw tremor at rest in the absence of other clear features of parkinsonism, mild kinetic tremor of the hands and, in the last year of life, a score of 22/41 on a cognitive screen. A senior movement disorder neurologist raised doubt about the “ET” diagnosis. The history and videotaped examination were reviewed by three additional senior tremor experts, who raised a number of diagnostic possibilities. A complete postmortem examination was performed by a senior neuropathologist, and was notable for the presence of tufted astrocytes, AT8-labeled glial cytoplasmic inclusions, and globose neuronal tangles. These changes were widespread and definitive. A neuropathological diagnosis of progressive supranuclear palsy was assigned. Discussion This case presents with mixed and difficult to clinically classify tremor phenomenology and other neurological findings. The postmortem diagnosis was not predicted based on the clinical features, and it is possible that it does not account for all of the features. The case raises many interesting issues and provides a window into the complexity of the interpretation, nosology, and classification of tremor phenomenology. PMID:23864988

Mycoplasma pneumoniae-associated encephalitis in childhood--nervous system disorder during or after a respiratory tract infection.

2011-07-01

Mycoplasma pneumoniae is an important aetiological agent of encephalitis in children, with encephalitis being the most frequent paediatric extrapulmonary manifestation of M. pneumoniae infections. Evidence of M. pneumoniae involvement in childhood encephalitis is difficult to obtain, because M. pneumoniae is seldom detected in the cerebrospinal fluid and the clinical picture shows gradual onset. Therefore, we present a small case-study as a paradigm of M. pneumoniae-associated encephalitis in childhood and illustrate the importance of this entity based on a review of previously published cases. We describe neurological signs and symptoms of 2 patients with M. pneumoniae-associated encephalitis in childhood. Respiratory symptoms with fever occurred in both children. They were seropositive for M. pneumoniae, but did not have the organism detected by PCR from cerebrospinal fluid. No long-term neurologic sequelae occurred. M. pneumoniae has to be considered as a responsible pathogen of encephalitis in children, even if respiratory symptoms do not occur. Due to the seldom detection of M. pneumoniae in cerebrospinal fluid, evidence of m. pneumoniae involvement in childhood encephalitis is difficult to obtain.Faced with a neurological disease with no organism detected in CNS in the majority of cases assumes that M. pneumoniae-associated encephalitis is most likely a paradigm for an autoimmune disease with uniform pathogenesis mediated by an immunologic response to an antecedent antigenic stimulus from M. pneumoniae. It is important to relate this organism to this relatively common and potentially devastating clinical syndrome. © Georg Thieme Verlag KG Stuttgart · New York.

Toxocara is a roundworm, a common parasite of dogs (T. canis) and cats (T. cati). Toxocariasis or Visceral larva migrans (VLM) are diseases caused by the larvae of Toxocara sp., which may involve many organs, but pulmonary symptoms such as coughing and wheezing and allergic symptoms are seen in more than 80% of patients. It is known that, although the risk of infection is present, the worldwide diagnosis of toxocariasis is difficult since clinical and laboratory data provide insufficient evidence for the diagnosis. Nowadays, the diagnosis of toxocariasis is performed by serologic methods. We describe herein a case of toxocariasis with eosinophilic pneumonia that was diagnosed using serologic methods.

Strokes impact over 800,000 people every year. Stroke care typically begins with inpatient care and then continues across an array of healthcare settings. These transitions are difficult for patients and caregivers, with psychosocial needs going unmet. Our team developed a case management intervention for acute stroke patients and their caregivers aimed at improving stroke transitions. The intervention focusses on four aspects of a successful care transition: support, preparedness, identifying and addressing unmet needs, and stroke education. This paper describes the development and implementation of this program, and is an example of the synergy created between neuroscience and clinical practice.

Epithelioid angiomyolipomas, or perivascular epithelioid cell tumors (epithelioid PEComas) of the kidney, are histologically related to renal angiomyolipomas (AMLs). However, in contrast to typical AMLs, this rare tumor can exhibit an aggressive clinical course with approximately 50% of reported cases demonstrating disease progression. In this report, we present a case of a 24-year-old female with a history of stone disease who was incidentally found to have a 9.0 cm right renal mass that was difficult to characterize radiographically preoperatively. The patient underwent a right radical nephrectomy, and pathology revealed a renal epithelioid PEComa.

2018-01-01

Summary The current report presents a case of an omental fibromatosis discovered incidentally in a 46-year-old woman with no particular medical history and few symptoms. A surgical biopsy was performed initially, and microscopic examination revealed myofibroblastic proliferation. After additional immunohistochemical and molecular analyses, omental fibromatosis was diagnosed. Omental fibromatosis, also called intra-abdominal desmoid, is a rare and benign tumour but can be locally aggressive. Majority of cases are asymptomatic, and difficult to diagnose based on clinical presentation and radiological investigation. Final diagnosis is usually made on histopathology and immunohistochemistry studies. Surgical wide excision is currently the treatment of choice. PMID:29552447

Gorham disease is a so-called massive idiopathic osteolysis or vanishing bone disorder. Massive osteolysis remains an enigmatic condition that involves various skeletal locations and is caused by endothelial proliferation. The diagnosis is difficult and is established via the association of clinical, radiologic and histologic pictures. Treatment modalities yield variable results. We report a case of vanishing bone in the elbow joint and carpal bones following trauma. This 13-year-old boy complained of severe restricted motion and deformity of the right elbow. We managed the problem using arthroplasty with close-wedge osteotomy on the lateral condyle of the humerus.

The study describes four cases of tularaemia - one developed after contact with rabbits and three developed after an arthropod bite. Due to non-specific clinical symptoms, accurate diagnosis of tularaemia may be difficult. The increasing contribution of the arthropod vectors in the transmission of the disease indicates that special effort should be made to apply sensitive and specific diagnostic methods for tularaemia, and to remind health-care workers about this route of Francisella tularensis infections. The advantages and disadvantages of various diagnostic methods - molecular, serological and microbiological culture - are discussed. The PCR as a rapid and proper diagnostic method for ulceroglandular tularaemia is presented.

Differences in the perception of seven behaviour-modifying techniques in paediatric dentistry by undergraduate students using lecturing and video sequences for teaching.

PubMed

2010-11-01

Whilst preparing undergraduate students for a clinical course in paediatric dentistry, four consecutive classes (n = 107) were divided into two groups. Seven behaviour-modifying techniques were introduced: systematic desensitization, operant conditioning, modelling, Tell, Show, Do-principle, substitution, change of roles and the active involvement of the patient. The behaviour-modifying techniques that had been taught to group one (n = 57) through lecturing were taught to group two (n = 50) through video sequences and vice versa in the following semester. Immediately after the presentations, students were asked by means of a questionnaire about their perceptions of ease of using the different techniques and their intention for clinical application of each technique. After completion of the clinical course, they were asked about which behaviour-modifying techniques they had actually used when dealing with patients. Concerning the perception of ease of using the different techniques, there were considerable differences for six of the seven techniques (P < 0.05). Whilst some techniques seemed more difficult to apply clinically after lecturing, others seemed more difficult after video-based teaching. Concerning the intention for clinical application and the actual clinical application, there were higher percentages for all techniques taught after video-based teaching. However, the differences were significant only for two techniques in each case (P < 0.05). It is concluded that the use of video based teaching enhances the intention for application and the actual clinical application only for a limited number of behaviour-modifying techniques. © 2010 John Wiley & Sons A/S.

Pituitary gigantism is a rare condition caused by growth hormone secreting hypersecretion, usually by a pituitary tumor. Acromegaly and gigantism cases that have a genetic cause are challenging to treat, due to large tumor size and poor responses to some medical therapies (e.g. AIP mutation affected cases and those with X-linked acrogigantism syndrome). We performed a retrospective study to identify gigantism cases among 160 somatotropinoma patients treated between 1985 and 2015 at the University Hospital of Caracas, Venezuela. We studied clinical details at diagnosis, hormonal responses to therapy and undertook targeted genetic testing. Among the 160 cases, eight patients (six males; 75 %) were diagnosed with pituitary gigantism and underwent genetic analysis that included array comparative genome hybridization for Xq26.3 duplications. All patients had GH secreting pituitary macroadenomas that were difficult to control with conventional treatment options, such as surgery or primary somatostatin receptor ligand (SRL) therapy. Combined therapy (long-acting SRL and pegvisomant) as primary treatment or after pituitary surgery and radiotherapy permitted the normalization of IGF-1 levels and clinical improvement. Novel AIP mutations were the found in three patients. None of the patients had Xq26.3 microduplications. Treatment of pituitary gigantism is frequently challenging; delayed control increases the harmful effects of GH excess, such as, excessive stature and symptom burden, so early diagnosis and effective treatment are particularly important in these cases.

Cryptorchism is an inherited congenital abnormality characterized by the failure of one or both testes to descend into the scrotum. Diagnosis can be difficult if the retained testicular tissue cannot be localized during clinical examination and the history of the animal is unknown, or if the animal shows persistent male behaviour despite the history of successful previous castration. The present case report describes the history of a cryptorchid Lama and the techniques of general anesthesia and laparoscopic cryptorchidectomy advocated.

Infratemporal space infection is a rare but serious sequel of odontogenic infection. The diagnosis is difficult due to non spe-cific signs and symptoms. Diabetes mellitus as a definitive risk factor for odontogenic infections needs more consideration during clinical procedures. We report a case of an undiagnosed diabetic patient with isolated infratemporal space infection after tooth extraction with presentation of similar signs and symptoms of temporomandibular joint and muscle problem.

Primary cardiac lymphoma is classically defined as an extranodal non-Hodgkin's lymphoma exclusively located in the heart and/or pericardium. However, over the last few years, this definition has been extended to include other localizations on condition that these are clearly less important then a cardiac site, that must remain the first, during the illness course, and the most important for its entity. PCL is extremely rare in immunocompetent patients, accounting for 1.3% of all cardiac tumours and 0.5% of all extranodal lymphomas, but it has been encountered with increasing frequency in patients with AIDS or other severe immunodepressive syndromes. PCL is difficult to diagnose, especially during the early stage of the disease, because of its non-specific clinical manifestations, the limited possibility of using non-invasive diagnostic techniques, and difficulties or delays in applying invasive methods. The malignancy of its histotypes and its delicate location are responsible for its rapid and frequently unfavourable evolution. Successful treatment, which is mainly based on anthracycline-containing polychemotherapies, is heavily dependent on an early diagnosis. After a general review of the literature, the authors describe the clinical case of a patient with a PCL that had a secondary central nervous system location, treated with polychemotherapy and autologous peripheral blood stem cell transplantation. Emphasis is placed on the fact that it is more difficult to eradicate the disease from the central nervous system than from the heart.

To study the clinical, pathological and immunophenotypic characteristics of the primary breast lymphoma (PBL). Analyses of clinical history, preoperative findings, histological and immunohistochemical features of eight patients with PBL were performed. Malignant lymphoma was difficult to diagnose preoperatively. All patients were women. The age range was from 34 approximately 65 years (mean 46.4 years). The right breast was involved initially in three patients, the left in four. One patient presented bilateral involvement. Seven patients were assessed at stage IE, one with ipsolateral axillary lymph nodes involvement at stage IIE. According to the WHO classification, five patients were diagnosed as diffuse large B-cell lymphoma (4/5 centroblast, 1/5 immunoblast); the other three patients as MALT lymphoma, all with lymphoepithelial lesions. The paraffin-embedded tissues of all cases showed immunoreactivity for B-cell markers CD20, CD45RA. CD5 and CD10 were negative in all cases. Follow-up data were obtained in six patients, none recurred or died within 8 to 108 months after diagnosis. This study indicates that most PBL are diffuse large B-cell lymphoma and MALT lymphoma and have a better prognosis after comprehensive therapy.

Male, 64 FINAL DIAGNOSIS: Lung pleomorphic carcinoma Symptoms: Cough • fever - Clinical Procedure: - Specialty: Oncology. Unusual clinical course. The diagnosis of lung cancer is often made based on computed tomography (CT) image findings if it cannot be confirmed on pathological examinations, such as bronchoscopy. However, the CT image findings of cancerous lesions are similar to those of abscesses.We herein report a case of lung cancer that resembled a lung abscess on CT. We herein describe the case of 64-year-old male who was diagnosed with lung cancer using surgery. In this case, it was quite difficult to distinguish between the lung cancer and a lung abscess on CT images, and a lung abscess was initially suspected due to symptoms, such as fever and coughing, contrast-enhanced CT image findings showing a ring-enhancing mass in the right upper lobe and the patient's laboratory test results. However, a pathological diagnosis of lung cancer was confirmed according to the results of a rapid frozen section biopsy of the lesion. This case suggests that physicians should not suspect both a lung abscesses and malignancy in cases involving masses presenting as ring-enhancing lesions on contrast-enhanced CT.

BACKGROUND Vitiligo, also known as leukoderma, is an autoimmune skin condition that results in the loss of melanin pigment. Vitiligo is not a rare condition but is difficult to treat and is associated with psychological distress. CASE REPORT A series of 14 cases of vitiligo are presented that were treated with individualized homeopathic remedies that were based on plant, animal, or mineral compounds. There were 13 women and one man in the case series, with a mean age 29.8 years, and a mean follow-up from treatment of 58 months. The mean time between the onset of the appearance of vitiligo and the first consultation at our clinic was 96 months. Homeopathic treatment for patients is holistic and was performed on an individualized basis as described in this case series. Photographic images of the skin are presented before and after treatment. CONCLUSIONS In 14 patients with vitiligo treated with individualized homeopathy, the best results were achieved in the patients who were treated in the early stages of the disease. We believe that homeopathy may be effective in the early stages of vitiligo, but large controlled clinical studies are needed in this area.

Geotrichum capitatum infection has a very low incidence rate with atypical clinical symptoms, making diagnosis difficult, and it has a poor prognosis. The incidence is even more rare in China. This paper reports the first case of infection caused by G. capitatum during bone marrow suppression after chemotherapy in a Chinese patient with acute lymphoblastic leukemia. In addition, it reports a systematic literature review of diagnosis and treatment. The patient with acute lymphoblastic leukemia was confirmed to be infected with G. capitatum, involving lung, liver and skin, through a blood culture test. Caspofungin, amphotericin B loposome, and a combination therapy of amphotericin B liposome and voriconazole were used in succession for treatment. Despite normal body temperature and a slight improvement of clinical symptoms with the combination therapy treatment, the patient died 40 days after chemotherapy due to heart and lung failure.

1997-08-01

We report a case of idiopathic granulomatous mastitis in a 35-year-old Japanese woman, who came to our hospital complaining of a tender mass in her right breast. Because the results of initial aspiration cytology were considered highly suspicious for carcinoma, modified radical mastectomy was performed. However, the final histological diagnosis was granulomatous lobular mastitis with no evidence of malignancy. Idiopathic granulomatous mastitis is a rare inflammatory breast disease of unknown etiology. Since the clinical manifestations are similar to those of mammary carcinoma, this condition has been misdiagnosed as carcinoma and treated as such. A review of the literature revealed that idiopathic granulomatous mastitis has tended to occur in young patients with a history of childbirth or oral contraceptive usage. Clinical or imaging diagnosis has often been difficult. Complete resection or corticosteroid therapy can be recommended as the optimal treatment. Since 38% of patients experience recurrence, long-term follow-up is indicated.

Pseudodystonia is the term used to define abnormal postures, which are not due to the disorders of the basal ganglia and is encountered very rarely in clinical practice and often difficult to distinguish from true dystonia syndromes. We report a rare case of a battered woman who was managed as restricted resistant dystonia with pharmacotherapy and intrathecal baclofen and referred for considering deep brain stimulation (DBS). The patient turned out to be a case of pseudodystonia due to bilateral hip dislocation. This was due to assault by a close relative and the history was masked by the patient for more than one and a half years. In a patient with late onset dystonia, who is resistant to the recommended treatment for dystonia along with atypical clinical features and electrophysiological parameters, pseudodystonia should always be considered as a possible diagnosis and evaluated for causes of the same.

A 41-year-old man visited our dermatology clinic because an eruption, which was resistant to steroid ointment treatment, had appeared on his right forearm. An oval, soybean-sized erythematous infiltrated lesion with scales and crusts was located in the central part of the extensor surface of the right forearm and showed partial erosion with attached yellow crusts. The lesion had an impetigo-like appearance. Fungal elements were confirmed from the scales by KOH examination and the fungus was identified as Trichophyton tonsurans by fungal culture and molecular method. Clinical features of T. tonsurans infection vary, wherein some patients have strong inflammatory manifestations, while others remain as asymptomatic carriers. Especially at the early stage of the infection, diagnosis is difficult because it is often misdiagnosed as eczema. We report a case of T. tonsurans infection that had impetigo-like appearance. We also studied the mechanism of the disease.

Myxedema coma is the extreme form of untreated hypothyroidism. In reality, few patients present comatose with severe myxedema. We describe a patient with myxedema coma which was initially misdiagnosed as a brain stem infarct. She presented to the hospital with alteration of the mental status, generalized edema, hypothermia, hypoventilation, and hypotension. Initially her brain stem reflexes were absent. After respiratory and circulatory support, her neurologic status was not improved soon. The diagnosis of myxedema coma was often missed or delayed due to various clinical findings and concomitant medical condition and precipitating factors. It is more difficult to diagnose when a patient has no medical history of hypothyroidism. A high index of clinical suspicion can make a timely diagnosis and initiate appropriate treatment. We report this case to alert clinicians considering diagnosis of myxedema coma in patients with severe decompensated metabolic state including mental change. PMID:20808690

Mucormycosis in Children: Review and Recommendations for Management.

PubMed

Francis, Joshua R; Villanueva, Paola; Bryant, Penelope; Blyth, Christopher C

2018-05-15

Mucormycosis represents the third most common invasive fungal infection in children, and recent studies have suggested a rising incidence. Its case fatality rate is high, especially for neonates. Clinical presentation is influenced by underlying risk factors; associations with immunosuppression, neutropenia, diabetes, and prematurity have been described. It has been implicated in several hospital outbreaks. Diagnosis requires a high index of suspicion and evaluation with histopathology, culture, and, increasingly, molecular identification. Surgical debridement and antifungal therapies are the cornerstone for combatting invasive mucormycosis. However, the severity and relative rarity of this disease make comparative clinical trials for evaluating antifungal therapies in children difficult to conduct. Hence, therapeutic decisions are derived mainly from retrospective case series, in vitro data, and animal models. In this review, we summarize the literature on the epidemiology and diagnosis of this invasive fungal infection and provide suggestions on the management of mucormycosis in children.

Optimising Use of Electronic Health Records to Describe the Presentation of Rheumatoid Arthritis in Primary Care: A Strategy for Developing Code Lists

Nicholson, Amanda; Ford, Elizabeth; Davies, Kevin A.; Smith, Helen E.; Rait, Greta; Tate, A. Rosemary; Petersen, Irene; Cassell, Jackie

2013-01-01

Background Research using electronic health records (EHRs) relies heavily on coded clinical data. Due to variation in coding practices, it can be difficult to aggregate the codes for a condition in order to define cases. This paper describes a methodology to develop ‘indicator markers’ found in patients with early rheumatoid arthritis (RA); these are a broader range of codes which may allow a probabilistic case definition to use in cases where no diagnostic code is yet recorded. Methods We examined EHRs of 5,843 patients in the General Practice Research Database, aged ≥30y, with a first coded diagnosis of RA between 2005 and 2008. Lists of indicator markers for RA were developed initially by panels of clinicians drawing up code-lists and then modified based on scrutiny of available data. The prevalence of indicator markers, and their temporal relationship to RA codes, was examined in patients from 3y before to 14d after recorded RA diagnosis. Findings Indicator markers were common throughout EHRs of RA patients, with 83.5% having 2 or more markers. 34% of patients received a disease-specific prescription before RA was coded; 42% had a referral to rheumatology, and 63% had a test for rheumatoid factor. 65% had at least one joint symptom or sign recorded and in 44% this was at least 6-months before recorded RA diagnosis. Conclusion Indicator markers of RA may be valuable for case definition in cases which do not yet have a diagnostic code. The clinical diagnosis of RA is likely to occur some months before it is coded, shown by markers frequently occurring ≥6 months before recorded diagnosis. It is difficult to differentiate delay in diagnosis from delay in recording. Information concealed in free text may be required for the accurate identification of patients and to assess the quality of care in general practice. PMID:23451024

Ulcerative colitis is exceptional in Africa South of the Sahara. The first case was described in 1964: up to 1982, 46 cases were reported. We report on 14 cases (6 females and 8 males) observed in black Senegalese for three years and a half. The medium age of patients was 30 years. All of them had a high social standard of living. Four patients showed intestinal amebiasis in their previous medical history. Clinical and evolutive patterns of ulcerative colitis in Africa present few differences in comparison with the classical ones. The diagnosis is established by endoscopy (rectosigmoidoscopy and/or colonoscopy) and histopathology. Cryptic abscesses were found in only 2 out of 14 cases. Rectal dysplasia was noted in 2 cases. The course of the disease developed on a fulminating acute mode in one case, on a continuous chronic mode in another case and on a chronic mode with relapses in 11 cases. Irrespective to the clinical form observed, intestinal amebiasis represents the most pressing differential diagnosis. Treatment appears to be difficult in severe acute forms out of an intensive care department, as well as in advanced extensive chronic forms. For the later in black Africa endoscopic and histopathological surveillance appears to be preferable to a total colectomy, made necessary by the important rectal lesions, because the functional sequelae of an ileostomy.

Primary amenorrhea is a common diagnostic challenge in the gynecology department, wherein there are numerous causes that need to be approached in a systematic manner. However, when a case with a pelvic lump or a solid pelvic mass presents to a gynecologist or a radiologist, the approach becomes difficult to justify amenorrhea and pelvic mass as a single entity. We present the case of a 36-year-old female with the complaints of primary amenorrhea with a pelvic mass. The case was approached keeping in view the diagnostic possibilities and applying the role of clinical, radiological, and laboratory analyses. The final diagnosis of Swyer syndrome with gonadoblastoma was made, and she was further subjected to operative resection and hormonal therapy. This study stresses on the approach to a case, wherein the diagnosis was based only on the clinician's acumen and the radiologist's expertise, providing a way to simplify the protocol in the evaluation of such types of cases.

AIM: Acquired hepatocerebral degeneration (AHD) is an exceptional type of hepatic encephalopathies (HE). It is characterized by neuropsychiatric and extrapyramidal symptomathology similar to that seen in hepatolenticular degeneration (Wilson’s disease). In this paper, we report a case of AHD with unusual presenting features. METHODS: A 28-year-old man with AHD was described and the literature was reviewed. RESULTS: The man had a history of HBV-related liver cirrhosis. He was admitted to our hospital with apathy, dysarthria, mild consciousness impairment and extrapyramidal symptoms after hematemesis. By review of the literature, cases with AHD often did not present consciousness impairment. So our case was once diagnosed incorrectly as Wilson’s disease. CONCLUSION: AHD is a rare syndrome and its variable clinical manifestations make it difficult to be diagnosed. But we believe that extensive examination and thorough understanding of the disease are beneficial to a correct diagnosis. Moreover, biocoene is effective in treating the case. PMID:15655841

Inverted follicular keratosis (IFK) is a rare benign tumor which usually appears as a firm papule on the face. The diagnosis is generally made by histopathology because the clinical appearance is difficult to differentiate from other lesions. Dermoscopic features of IFK have not been established to date. Herein we describe the dermoscopic findings of 4 cases of IFK. Radial peripheral hairpin vessels surrounded by a whitish halo arranged around a central white-yellowish amorphous area were observed in 3 cases, and glomerular vessels were present in the central area of one of them. The fourth case also presented a central white amorphous area but showed arborizing vessels. Reflectance confocal microscopy (available in 1 case) revealed a broadened honeycomb pattern, epidermal projections and hairpin and glomerular vessels. To our knowledge this is the first case series describing the dermoscopic features of inverted follicular keratosis and the first confocal microscopy description of this entity.

Video observation in HIT development: lessons learned on benefits and challenges.

Experience shows that the precondition for the development of successful health information technologies is a thorough insight into clinical work practice. In contemporary clinical work practice, clinical work and health information technology are integrated, and part of the practice is tacit. When work practice becomes routine, it slips to the background of the conscious awareness and becomes difficult to recognize without the context to support recall. This means that it is difficult to capture with traditional ethnographic research methods or in usability laboratories or clinical set ups. Observation by the use of the video technique within healthcare settings has proven to be capable of providing a thorough insight into the complex clinical work practice and its context - including parts of the tacit practice. The objective of this paper is 1) to argue for the video observation technique to inform and improve health-information-technology development and 2) to share insights and lessons learned on benefits and challenges when using the video observation technique within healthcare settings. A multiple case study including nine case studies conducted by DaCHI researchers 2004-2011 using audio-visual, non-participant video observation for data collection within different healthcare settings. In HIT development, video observation is beneficial for 1) informing and improving system design 2) studying changes in work practice 3) identifying new potentials and 4) documenting current work practices. The video observation technique used within healthcare settings is superior to other ethnographic research methods when it comes to disclosing the complexity in clinical work practice. The insights gained are far more realistic compared to traditional ethnographic studies or usability studies and studies in clinical set ups. Besides, the data generated through video recordings provide a solid basis for dialog between the health care professionals involved. The most important lessons learned are that a well considered methodology and clear formulated objectives are imperative, in order to stay focused during the data rich analysis phase. Additionally, the video observation technique is primarily recommended for studies of specific clinical work practices within delimited clinical settings. Overall, the video observation technique has proven to be capable of improving our understanding of the interwoven relation between clinical work practice and HIT and to inform us about user requirements and needs for HIT, which is a precondition for the development of more successful HIT systems in the future.

2016-01-01

Background An unexpected difficult intubation can be very challenging and if it is not managed properly, it may expose the encountered patient to significant risks. The intubation difficulty scale (IDS) has been used as a validated method to evaluate a global degree of intubation difficulty. The aims of this study were to evaluate the prevalence and characteristics of unexpected difficult intubation using the IDS. Methods We retrospectively reviewed 951 patients undergoing elective surgery in a single medical center. Patients expected to have a difficult intubation or who had history of difficult intubation were excluded. Each patient was assessed by the IDS scoring system with seven variables. Total prevalence of difficult intubation and the contributing individual factors were further analyzed. Results For the 951 patients, the difficult intubation cases presenting IDS > 5 was 5.8% of total cases (n = 55). The prevalence of Cormack-Lehane Grade 3 or 4 was 16.2% (n = 154). Most of the difficult intubation cases were managed by simple additional maneuvers and techniques such as stylet application, additional lifting force and laryngeal pressure. Conclusions Unexpected difficult airway was present in 5.8% of patients and most was managed effectively. Among the components of IDS, the Cormack-Lehane grade was most sensitive for predicting difficult intubation. PMID:27274369

The retrospective diagnosis of illnesses by medical historians can often be difficult and prone to bias, although knowledge of the medical disorders of historical figures is key to the understanding of their behavior and reactions. The recent application of computer diagnostics to historical figures allows an objective differential diagnosis to be accomplished. Taking an example from clinical neurology, we analyzed the earliest reported cases of Devic's disease (neuromyelitis optica) that commonly affects the optic nerve and spinal cord and was previously often confused with multiple sclerosis. We conclude that in most identified cases the software concurred with the contemporary physicians' interpretation, but some claimed cases either had insufficient data to provide a diagnosis or other possible diagnoses were suggested that had not been considered. Computational methods may, therefore, help historians to diagnose the ailments of historical figures with greater objectivity.

Background In 2015, Brazil was faced with the cocirculation of three arboviruses of major public health importance. The emergence of Zika virus (ZIKV) presents new challenges to both clinicians and public health authorities. Overlapping clinical features between diseases caused by ZIKV, Dengue (DENV) and Chikungunya (CHIKV) and the lack of validated serological assays for ZIKV make accurate diagnosis difficult. Methodology / Principal Findings The outpatient service for acute febrile illnesses in Fiocruz initiated a syndromic clinical observational study in 2007 to capture unusual presentations of DENV infections. In January 2015, an increase of cases with exanthematic disease was observed. Trained physicians evaluated the patients using a detailed case report form that included clinical assessment and laboratory investigations. The laboratory diagnostic algorithm included assays for detection of ZIKV, CHIKV and DENV. 364 suspected cases of Zika virus disease were identified based on clinical criteria between January and July 2015. Of these, 262 (71.9%) were tested and 119 (45.4%) were confirmed by the detection of ZIKV RNA. All of the samples with sequence information available clustered within the Asian genotype. Conclusions / Significance This is the first report of a ZIKV outbreak in the state of Rio de Janeiro, based on a large number of suspected (n = 364) and laboratory confirmed cases (n = 119). We were able to demonstrate that ZIKV was circulating in Rio de Janeiro as early as January 2015. The peak of the outbreak was documented in May/June 2015. More than half of the patients reported headache, arthralgia, myalgia, non-purulent conjunctivitis, and lower back pain, consistent with the case definition of suspected ZIKV disease issued by the Pan American Health Organization (PAHO). However, fever, when present, was low-intensity and short-termed. In our opinion, pruritus, the second most common clinical sign presented by the confirmed cases, should be added to the PAHO case definition, while fever could be given less emphasis. The emergence of ZIKV as a new pathogen for Brazil in 2015 underscores the need for clinical vigilance and strong epidemiological and laboratory surveillance. PMID:27070912

Diagnosis of celiac disease is difficult when the combined results of serology and histology are inconclusive. Studies using flow cytometry of intraepithelial lymphocytes (IELs) have found that celiac patients have increased numbers of γδ IELs, along with a decrease in CD3-CD103 + IELs. The objective of this article is to assess the role of flow cytometric analysis of IELs in the diagnosis of celiac disease in difficult cases. A total of 312 patients with suspicion of celiac disease were included in the study. Duodenal biopsy samples were used for histological assessment and for flow cytometric analysis of IELs. In 46 out of 312 cases (14.7%) the combination of serology and histology did not allow the confirmation or exclusion of celiac disease. HLA typing had been performed in 42 of these difficult cases. Taking into account HLA typing and the response to a gluten-free diet, celiac disease was excluded in 30 of these cases and confirmed in the remaining 12. Flow cytometric analysis of IELs allowed a correct diagnosis in 39 out of 42 difficult cases (92.8%) and had a sensitivity of 91.7% (95% CI: 61.5% to 99.8%) and a specificity of 93.3% (95% CI: 77.9% to 99.2%) for the diagnosis of celiac disease in this setting. Flow cytometric analysis of IELs is useful for the diagnosis of celiac disease in difficult cases.

Flow cytometric analysis of IELs allowed a correct diagnosis in 39 out of 42 difficult cases (92.8%) and had a sensitivity of 91.7% (95% CI: 61.5% to 99.8%) and a specificity of 93.3% (95% CI: 77.9% to 99.2%) for the diagnosis of celiac disease in this setting. Conclusion Flow cytometric analysis of IELs is useful for the diagnosis of celiac disease in difficult cases. PMID:29026596

Nonalcoholic steatohepatitis (NASH) is an important cause of liver-related morbidity and mortality. There are no approved therapies, and the results of clinical trials have been difficult to compare due to inconsistent definitions of relevant disease parameters in patients with NASH. The natural course of the disease has not been rigorously characterized, particularly with respect to the contributions of underlying obesity, type 2 diabetes, and other comorbidities and the treatments provided for these comorbidities. Efforts to perform analyses of pooled data are limited by heterogeneous case definitions used across studies to define disease states. There remains a major unmet need in the field to develop standardized definitions for populations for interventional trials. Such definitions are expected to impact how endpoints for clinical trials are constructed. The Liver Forum is a multistakeholder effort including US and European regulatory agencies, academic investigators, professional and patient representative organizations, and industry to catalyze therapeutic development for NASH by developing potential solutions to barriers to development. The Case Definitions Working Group was established by The Liver Forum to evaluate the validity of case definitions for populations to be included in clinical trials for NASH from a regulatory science perspective. Based on such analyses, specific recommendations are provided noting the strengths and weaknesses of the case definitions along with knowledge gaps that require additional study.

Factitious disease: clinical lessons from case studies at Baylor University Medical Center

PubMed Central

Savino, Adria C.; Fordtran, John S.

2006-01-01

Factitious disease is defined as the intentional production (or feigning) of disease in oneself to relieve emotional distress by assuming the role of a sick person. Although the self-induction of disease is a conscious act, the underlying motivation is usually unconscious. It has been estimated that 3% to 5% of physician-patient encounters involve factitious disease. This article presents 6 case studies from Baylor University Medical Center that highlight various clinical aspects of factitious disease. Patients with factitious diseases are extremely difficult to recognize because they do not appear different from patients with authentic causes of similar symptoms, because their psychiatric abnormalities are not appreciated, and because doctors and nurses have alowindex of suspicion. Since patients with factitious disease present a false medicalhistory, their physicians prescribe unnecessary procedures and therapies that may result in iatrogenic disease. In many cases, damage to these patients from doctors' actions exceeds the harm resulting from the patients' self-induced illness. The clues that should suggest factitious disease, the diagnostic roles of the clinician and a consulting psychiatrist, and the ethical conflicts that confront doctors taking care of such patients are discussed. To help keep factitious disease in clinical perspective, one of the case studies involves the antithesis of factitious disease, where a patient was mistakenly diagnosed as having psychogenic pain when in fact the symptoms were caused by an overlooked physical disease. Better knowledge of the clinical features of factitious disease might have prevented the disastrous outcome. PMID:17252033

The role of hypoxia in oral cancer and potentially malignant disorders: a review.

PubMed

Kujan, Omar; Shearston, Kate; Farah, Camile S

2017-04-01

Oral and oropharyngeal cancer are major health problems globally with over 500 000 new cases diagnosed annually. Despite the fact that oral cancer is a preventable disease and has the potential for early detection, the overall survival rate remains at around 50%. Most oral cancer cases are preceded by a group of clinical lesions designated 'potentially malignant disorders'. It is difficult to predict if and when these lesions may transform to malignancy, and in turn it is difficult to agree on appropriate management strategies. Understanding underlying molecular pathways would help in predicting the malignant transformation of oral potentially malignant disorders and ultimately identifying effective methods for early detection and prevention of oral cancer. Reprogramming energy metabolism is an emerging hallmark of cancer that is predominantly controlled by hypoxia-induced genes regulating angiogenesis, tumour vascularization, invasion, drug resistance and metastasis. This review aims to highlight the role of hypoxia in oral carcinogenesis and to suggest future research implications in this arena. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

It's not all about moral reasoning: Understanding the content of Moral Case Deliberation.

PubMed

Svantesson, Mia; Silén, Marit; James, Inger

2018-03-01

Moral Case Deliberation is one form of clinical ethics support described as a facilitator-led collective moral reasoning by healthcare professionals on a concrete moral question connected to their practice. Evaluation research is needed, but, as human interaction is difficult to standardise, there is a need to capture the content beyond moral reasoning. This allows for a better understanding of Moral Case Deliberation, which may contribute to further development of valid outcome criteria and stimulate the normative discussion of what Moral Case Deliberation should contain. To explore and compare the content beyond moral reasoning in the dialogue in Moral Case Deliberation at Swedish workplaces. A mixed-methods approach was applied for analysing audio-recordings of 70 periodic Moral Case Deliberation meetings at 10 Swedish workplaces. Moral Case Deliberation facilitators and various healthcare professions participated, with registered nurses comprising the majority. Ethical considerations: No objection to the study was made by an Ethical Review Board. After oral and written information was provided, consent to be recorded was assumed by virtue of participation. Other than 'moral reasoning' (median (md): 45% of the spoken time), the Moral Case Deliberations consisted of 'reflections on the psychosocial work environment' to a varying extent (md: 29%). Additional content comprised 'assumptions about the patient's psychosocial situation' (md: 6%), 'facts about the patient's situation' (md: 5%), 'concrete problem-solving' (md: 6%) and 'process' (md: 3%). The findings suggest that a restorative function of staff's wellbeing in Moral Case Deliberation is needed, as this might contribute to good patient care. This supports outcome criteria of improved emotional support, which may include relief of moral distress. However, facilitators need a strategy for how to proceed from the participants' own emotional needs and to develop the use of their emotional knowing to focus on the ethically difficult patient situation.

Drug-resistant strains of tuberculosis (TB) represent a major threat to global TB control. In low- and middle-income countries, resource constraints make it difficult to identify and monitor cases of resistance using drug susceptibility testing and culture. Molecular assays such as the GeneXpert Mycobacterium tuberculosis/rifampicin may prove to be a cost-effective solution to this problem in these settings. The objective of this study is to evaluate the use of GeneXpert in the diagnosis of pulmonary TB since it was introduced into two tertiary hospitals in Ghana in 2013. A 2-year retrospective audit of clinical cases involving patients who presented with clinically suspected TB or documented TB not improving on standard therapy and had samples sent for GeneXpert testing. GeneXpert identified 169 cases of TB, including 17 cases of rifampicin-resistant TB. Of the seven cases with final culture and drug susceptibility testing results, six demonstrated further drug resistance and five of these were multidrug-resistant TB. These findings call for a scale-up of TB control in Ghana and provide evidence that the expansion of GeneXpert may be an optimal means to improve case finding and guide treatment of drug-resistant TB in this setting.

2017-01-01

There are here described a number of basic principles underlying an effective clinical interview in psychiatric difficult situations (violent or suicidal patients, victims of serious physical and psychological damages, authors of inadequate or anti-social requests to the therapist). The aim of the present study is to provide the psychiatric operator with useful skills for the optimal management of the interview in difficult situations both at diagnostically and therapeutically level. The methodology was based on examination of the literature and personal experience of the authors. The authors highlighted 18 working hypothesis that may represent beneficial instruments in situations of difficult psychiatric interview. Further studies will deepen under the clinical, actuarial and statistical validity the principles covered in various clinical and crisis situations with difficulty to the interview, in relation also to specific types of patients for a more updated training of the operators in the field of mental health.

Mucous retention cysts of the parotid gland are rare, and a coexistent adenoid cystic carcinoma is even an unusual occurrence. Such coexistent adenoid cystic carcinomas with mucous retention cyst of the parotid gland are difficult to diagnose clinically and, at times, stage difficulty in their management. We report a rare case of adenoid cystic carcinoma associated with mucous retention cyst of the parotid gland with its diagnostic and management dilemma in a 14-year-old adolescent girl.

Balloon aortic valvuloplasty is a relatively simple procedure with a low rate of complications despite patients' frailty. Urgent balloon aortic valvuloplasty is especially useful in patients with temporary contra-indication to TAVI or in case of difficult clinical scenario. It allows for a functional improvement for up to 6 months. This period should be used to bridge the patient to TAVI or surgical aortic valve replacement, stand-alone aortic valvuloplasty being without mid-term survival benefit.

Imaging examinations are often performed in patients with Legionnaires' disease. The literature to date has documented that the imaging findings in this disorder are relatively nonspecific, and it is therefore difficult to prospectively differentiate legionella pneumonia from other forms of pneumonia, and from other noninfectious thoracic processes. Through a review of clinical cases and the literature, our objective is for the reader to gain a better understanding of the spectrum of radiographic manifestations of Legionnaires' disease.

2008-02-01

Making a diagnosis of transient non-ketotic hyperglycinaemia (tNKH) can be difficult. We report an infant who presented in the neonatal period with symptoms of NKH. Metabolic studies performed on day 2 of life showed raised cerebrospinal fluid (CSF) and plasma glycine, and a CSF:plasma glycine ratio consistent with NKH; however, a liver biopsy performed on day 5 revealed normal liver glycine cleavage system activity. Subsequently, the child's clinical condition improved in the absence of any therapeutic medication. Clinical assessment and developmental follow-up at 5 months, 1 year, and 2 years were age-appropriate. Guidance for the investigation and management of future suspected cases of tNKH is discussed.

2017-03-01

Tumor necrosis factor alpha (TNF alpha) antagonists are biologic agents used in the management of inflammatory conditions such as rheumatoid arthritis, seronegative spondyloarthropathies and inflammatory bowel disease. These agents have been recently shown to cause a syndrome called anti-TNF induced lupus (ATIL), a rare condition which has similar clinical manifestations to idiopathic systemic lupus erythematosus (SLE). Given that extra-intestinal manifestations of inflammatory bowel disease include arthritis, it can be difficult to separate arthritis due to underlying disease from drug-induced arthritis. We present a case of a 28-year-old female with Crohn's disease, who developed disabling arthritis as a clinical manifestation of ATIL following treatment with three anti-TNF agents, namely infliximab, adalimumab and certolizumab.

Henoch-Schönlein purpura (HSP) is systemic vasculitis disease with various clinical manifestations. Gastrointestinal symptoms in patients with HSP are usually common, with an incidence rate of 62-90%. Most of these gastrointestinal symptoms occur after typical skin purpura, which is a very important clinical evidence for making a diagnosis of HSP. It is difficult to diagnose HSP without skin rash. About 25% of patients may experience gastrointestinal symptoms as their first symptoms. Herein, we report a case of ileo-colic intussusception associated with HSP in a 5-years-old girl presented with diffuse abdominal distension. Our patient did present any symptoms of HSP, such as purpura, arthralgia or arthritis, before surgery.

Scope of practice: freedom within limits.

"Scope of practice" has a variety of meanings amongst midwives, other health professionals, health organizations, and consumers of midwifery care. For some, it refers to the Standards for the Practice of Midwifery; for others, it encompasses the legal base of practice; still others equate it with the components of the clinical parameters of practice. Because "scope of practice" is dynamic and parameters of practice can be impacted by many variables, succinctly defining "scope of practice" is difficult. This article provides a comprehensive discussion of the concept "scope of practice." Clinical scenarios are provided as case exemplars. The aim of this paper is to provide both new and experienced midwives with a substantive definition of the concept "scope of practice."

Clinical and research searching on the wild side: exploring the veterinary literature

Zoological medicine furthers the health and well-being of captive and free-ranging wild animals. Effective information retrieval of the zoological medicine literature demands searching multiple databases, conference proceedings, and organization websites using a wide variety of keywords and controlled vocabulary. Veterinarians, residents, students, and the librarians who serve them must have patience for multiple search iterations to capture the majority of the available knowledge. The complexities of thorough literature searches are more difficult for nondomestic animal clinical cases and research reviews as demonstrated by three search requests involving poisonous snakes, a gorilla, and spiders. Expanding and better disseminating the knowledgebase of zoological medicine will make veterinary searching easier. PMID:19626142

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome that results in renal phosphate wasting with hypophosphatemia. In most cases, the underlying cause of TIO is a small mesenchymal neoplasm that is often difficult to detect, resulting in delayed diagnosis. One such neoplasm is the phosphaturic mesenchymal tumor, mixed connective tissue variant (PMTMCT), an unusual entity with unique morphologic and biochemical features. Most of these tumors are found at appendicular sites with only rare cases reported in the jaws. We describe a PMTMCT involving the mandible in a patient with a protracted history of osteomalacia. A review of the current literature is provided with emphasis on the clinical and histologic features, etiopathogenesis, and management of PMTMCT in the setting of TIO.

2001-12-01

It is likely that lead poisoning via drinking water is often overlooked because of its supposed rarity and nonspecific early symptoms, which result in delayed management. One case of severe lead poisoning via drinking water is reported. The diagnosis was long missed and a particularly long chelating treatment was required. The clinical features included lead colic, a Burton's lead line, anemia, polyneuritis and arterial hypertension. Eighteen courses of calcium EDTA were required to obtain 'biological recovery'. The poisoning was linked to a very long water supply lead pipe and potomania secondary to alcohol withdrawal. This case report illustrates how difficult the early recognition of lead poisoning can be, and underlines the need to inquire about a toxic aetiology, particularly via the environment, of otherwise unexplained pathological conditions.

Adenocarcinoma is one of the most common malignant tumors of the small intestine complicating Crohn's disease. However, the coexistence of both conditions with diverticulosis of small bowel in young age makes this coincidence rare and clinical diagnosis very difficult. We report a case of a woman admitted to our Department with acute abdominal pain and fever. The surgical and histological investigation, revealed a rare coexistence that has never been mentioned in the published medical literature. Ileal diverticulosis is not frequent and often asymptomatic as well as adenocarcinoma of the small bowel. In this case, those diseases along with Crohn's disease led the patient to acute symptoms.

2014-11-01

Ovarian pregnancy constitutes 0.15-3% of all ectopic pregnancies. The incidence of ectopic pregnancy is on the rise owing to evolution in assisted reproductive techniques (ART). The incidence reported following In vitro fertilization (IVF) or embryo transfer (ET) is 0.27% per clinical pregnancy. We present a case of a 13-weeks ovarian pregnancy following IVF-ET and through a review of the literature, the specific symptomatology, diagnostic criteria, and treatment of this particular pathology will be described. Ovarian pregnancy is a rare condition and its diagnosis is difficult and relies on criteria based on intraoperative and histopathological findings. The management is, in spite of medical improvement, based on surgery. But the trend has shifted towards conservative surgeries in majority of cases.

Large bone defects present a difficult task for surgeons when performing single-stage, complex combined hindfoot and ankle reconstruction. There exist little data in a case series format to evaluate the use of frozen femoral head allograft during tibiotalocalcaneal arthrodesis in various populations in the literature. The authors evaluated 25 patients from 2003 to 2011 who required a femoral head allograft and an intramedullary nail. The average time of final follow-up visit was 83 ± 63.6 weeks (range, 10-265). Twelve patients healed the fusion (48%). Twenty-one patients resulted in a braceable limb (84%). Four patients resulted in major amputation (16%). This series may allow surgeons to more accurately predict the success and clinical outcome of these challenging cases. Level IV, case series. © The Author(s) 2014.

We present a case in which the origin of the branching vessel at the aneurysm neck was observed at the wrong place on the volume rendering method (VR) with 3D time-of-flight MRA (3D-TOF-MRA) with 3-Tesla MR system. In 3D-TOF-MRA, it is often difficult to observe the origin of the branching vessel, but it is unusual for it to be observed in the wrong place. In the planning of interventional treatment and surgical procedures, false recognition, as in the unique case in the present report, is a serious problem. Decisions based only on VR with 3D-TOF-MRA can be a cause of suboptimal selection in clinical treatment.

Posterior Rectus Sheath Hernia Causing Intermittent Small Bowel Obstruction

PubMed Central

2014-01-01

A posterior rectus sheath hernia is an abdominal wall hernia that is rarely encountered. Owing to its rarity, it can be easily overlooked in the setting of a patient presenting with abdominal pain. We report a case of a posterior rectus sheath hernia that caused intermittent small bowel obstruction. The unusual aspects of this case are that the defect was large, measuring 6 cm in the transverse diameter, and that it contained small bowel within a large portion of the rectus sheath. Because the defect was large and affected nearly the entire posterior rectus sheath, it was difficult to discern on computed tomography until a small bowel obstruction developed. In this case, a limited awareness of this clinical entity contributed to the delay in diagnosis. PMID:25426248

Management of Organic Mitral Regurgitation: Guideline Recommendations and Controversies

2015-01-01

Mitral regurgitation (MR) represents the second most frequent valvular heart disease. The appropriate management of organic MR remains unclear in many aspects, especially in several specific clinical scenarios. This review aims to discuss the current guideline recommendations regarding the management of organic MR, while highlighting the controversial aspects encountered in daily clinical practice. The role of imaging is essential in establishing the most appropriate type of surgical treatment (repair or replace), which is based on morphological mitral valve (MV) characteristics (reparability of the valve) and local surgical expertise in valve repair. The potential advantages of 3-dimensional echocardiography in assessing the MV are discussed. Other modern imaging techniques (tissue Doppler and speckle tracking) may provide additional useful information in borderline cases. Exercise echocardiography (evaluating MR severity, pulmonary pressure, or right ventricular function) may have an important role in the management of difficult cases. Finally, the moment when surgery is no longer an option and alternative solutions should be sought is also discussed. Although in everyday clinical practice the timing of surgery is not always straightforward, some newer clinical and echocardiographic indicators can guide this decision and help improve the outcome of these patients.

2012-04-01

Urea cycle disorders encompass several enzyme deficiencies that can result in cerebral damage, with a wide clinical spectrum from asymptomatic to severe. The goal of this study was to correlate brain MRI abnormalities in urea cycle disorders with clinical neurological sequelae to evaluate whether MRI abnormalities can assist in guiding difficult treatment decisions. We performed a retrospective chart review of patients with urea cycle disorders and symptomatic hyperammonemia. Brain MRI images were reviewed for abnormalities that correlated with severity of clinical neurological sequelae. Our case series comprises six urea cycle disorder patients, five with ornithine transcarbamylase deficiency and one with citrullinemia type 1. The observed trend in distribution of brain MRI abnormalities as the severity of neurological sequelae increased was the peri-insular region first, extending into the frontal, parietal, temporal and, finally, the occipital lobes. There was thalamic restricted diffusion in three children with prolonged hyperammonemia. Prior to death, this site is typically reported to be spared in urea cycle disorders. The pattern and extent of brain MRI abnormalities correlate with clinical neurological outcome in our case series. This suggests that brain MRI abnormalities may assist in determining prognosis and helping clinicians with subsequent treatment decisions.

Fistulectomy of the Parotid Fistula Secondary to Suppurative Parotitis: A Case Report

Managutti, Anil; Tiwari, Saba; Prakasam, Michael; Puthanakar, Nagaraj

2015-01-01

A parotid fistula is a communication between the skin and a parotid duct or gland through which saliva is discharged. The most common cause of the parotid fistula is trauma. The major causes of parotid trauma in a civilian practice are penetrating injury to the parotid gland from an assault weapon or injury due to shattered glass after a motor vehicle accident. Acute suppurative parotitis can rarely produce a parotid fistula, and it will be difficult to manage successfully. In this article we have described diagnosis by fistulography, meticulous dissection, and complete excision of the fistulous tract with layered closure of the parotid fascia followed by application of a post-operative pressure bandage, use of anticholinergic agents and antibiotics contribute significantly to the successful management of this difficult clinical condition.

The bogeyman cometh: a strategic approach for difficult adolescents.

PubMed

O'Connor, J J; Hoorwitz, A N

1984-06-01

Unpredictable and threatening events can sometimes alter one's view of reality. The altered perception may in turn result in altered forms of behavior and interaction with others. Deliberate efforts to facilitate this altered perception is sometimes attempted by invoking mythical forces such as the Bogeyman, Death, Satan, a shaman, or a sorcerer. Anthropological observations of shamanic magic suggest a number of components that appear to be responsible for these reality-altering experiences. These can be employed to create such experiences in the treatment of difficult adolescents for whom usual solutions have been ineffective. The experience results in systemic changes that render the adolescent accessible to more usual forms of treatment and more functional interactions with adults. The crafting of this kind of experience is illustrated in a case example. Parallels with other clinical practices as well as ethical considerations are discussed.

2003-01-01

Although clinical practice guidelines (CPGs) have been suggested as a means of encapsulating best practice in evidence-based medical treatment, their usage in clinical environments has been disappointing. Criticisms of guideline representations have been that they are predominantly narrative and are difficult to incorporate into clinical information systems. This paper analyses the use of UML process modelling techniques for guideline representation and proposes the automated generation of executable guidelines using XMI. This hybrid UML-XMI approach provides flexible authoring of guideline decision and control structures whilst integrating appropriate data flow. It also uses an open XMI standard interface to allow the use of authoring tools and process control systems from multiple vendors. The paper first surveys CPG modelling formalisms followed by a brief introduction to process modelling in UMI. Furthermore, the modelling of CPGs in UML is presented leading to a case study of encoding a diabetes mellitus CPG using UML.

TERMTrial--terminology-based documentation systems for cooperative clinical trials.

2005-04-01

Within cooperative groups of multi-center clinical trials a standardized documentation is a prerequisite for communication and sharing of data. Standardizing documentation systems means standardizing the underlying terminology. The management and consistent application of terminology systems is a difficult and fault-prone task, which should be supported by appropriate software tools. Today, documentation systems for clinical trials are often implemented as so-called Remote-Data-Entry-Systems (RDE-systems). Although there are many commercial systems, which support the development of RDE-systems there is none offering a comprehensive terminological support. Therefore, we developed the software system TERMTrial which consists of a component for the definition and management of terminology systems for cooperative groups of clinical trials and two components for the terminology-based automatic generation of trial databases and terminology-based interactive design of electronic case report forms (eCRFs). TERMTrial combines the advantages of remote data entry with a comprehensive terminological control.

Diagnostic Approach to Ocular Toxoplasmosis

Garweg, Justus G; de Groot-Mijnes, Jolanda DF; Montoya, Jose G

2011-01-01

Toxoplasmic retinochoroiditis is deemed a local event, which may fail to evoke a detectable systemic immune response. A correct diagnosis of the disease is a necessary basis for estimating its clinical burden. This is not so difficult in a typical clinical picture. In atypical cases, further diagnostic efforts are to be installed. Although the aqueous humor may be analyzed for specific antibodies or the presence of parasitic DNA, the DNA burden therein is low, and in rare instances a confirmation would necessitate vitreous sampling. A laboratory confirmation of the diagnosis is frustrated by individual differences in the time elapsing between clinical symptoms and activation of specific antibody production, which may result in false negatives. In congenital ocular toxoplasmosis, a delay in the onset of specific local antibody production could reflect immune tolerance. Herein, the authors attempt to provide a simple and practicable algorithm for a clinically tailored diagnostic approach in atypical instances. PMID:21770803

OBJECTIVE Intraventricular choroid plexus cysts are unusual causes of acute hydrocephalus in children. Radiological diagnosis of intraventricular choroid plexus cysts is difficult because they have very thin walls and fluid contents similar to CSF and can go undetected on routine CT studies. METHODS This study reports the authors' experience with 5 patients affected by intraventricular cysts originating from the choroid plexus. All patients experienced acute presentation with rapid neurological deterioration, sometimes associated with hypothalamic dysfunction, and required urgent surgery. In 2 cases the symptoms were intermittent, with spontaneous remission and sudden clinical deteriorations, reflecting an intermittent obstruction of the CSF pathway. RESULTS Radiological diagnosis was difficult in these cases because a nonenhanced CT scan revealed only triventricular hydrocephalus, with slight lateral ventricle asymmetry in all cases. MRI with driven-equilibrium sequences and CT ventriculography (in 1 case) allowed the authors to accurately diagnose the intraventricular cysts that typically occupied the posterior part of the third ventricle, occluding the aqueduct and at least 1 foramen of Monro. The patients were managed by urgent implantation of an external ventricular drain in 1 case (followed by endoscopic surgery, after completing a diagnostic workup) and by urgent endoscopic surgery in 4 cases. Endoscopic surgery allowed the shrinkage and near-complete removal of the cysts in all cases. Use of neuronavigation and a laser were indispensable. All procedures were uneventful, resulting in restoration of normal neurological conditions. Long-term follow-up (> 2 years) was available for 2 patients, and no complications or recurrences occurred. CONCLUSIONS This case series emphasizes the necessity of an accurate and precise identification of the possible causes of triventricular hydrocephalus. Endoscopic surgery can be considered the ideal treatment of choroid plexus cysts in children.

Intracranial chondroma is a rare and benign tumor with usual onset in young adulthood. The skull base is the most common site of occurrence although, less often, the tumors can appear at the falx cerebri or at the dural convexity. The differentiation of these lesions from meningiomas through imaging is generally difficult. Clinical case presentation and review of the current literature. We report a case of a 25-year-old male patient with a giant convexity chondroma with meningeal attachment in the right frontal lobe that was detected after a first generalized seizure. Based on the putative diagnosis of meningioma, the tumor was completely resected via an osteoplastic parasagittal craniotomy. The postoperative MRI confirmed the complete tumor resection. Histopathological analysis revealed the presence of a chondroma. Intracranial chondromas are a rarity and their preoperative diagnosis based on neuroimaging is difficult. In young patients and those with skeletal disease, the differential diagnosis of a chondroma should be considered. In symptomatic patients, operative resection is sensible. In most cases total removal of the tumor is possible and leads to full recovery. When the finding is merely incidental in older patients, a watchful waiting approach is acceptable, given the benign and slow-growing nature of the lesion. Copyright © 2018 Elsevier B.V.

Severe angioedema in myxedema coma: a difficult airway in a rare endocrine emergency.

PubMed

Lee, Christopher H; Wira, Charles R

2009-10-01

Myxedema coma is the most lethal manifestation of hypothyroidism. It is a true medical emergency and can result in profound hemodynamic instability and airway compromise. Myxedema coma currently remains a diagnostic challenge due to the rarity of cases seen today, and failure to promptly initiate therapy with replacement thyroid hormone can be fatal. As thyroid hormone therapy can take days or weeks to reverse the manifestations of myxedema coma, interim supportive therapy is critical while awaiting clinical improvement. Some patients will require endotracheal intubation in the emergency department (ED), and physicians should be aware that unanticipated posterior pharyngeal edema in myxedema coma could severely complicate airway management. Although mechanical ventilation is a well-described adjunctive therapy for myxedema coma, reports of the potential difficulty in securing a definitive airway in these patients are rare. We describe a case of an unidentified woman who presented to the ED with myxedema coma requiring urgent endotracheal intubation and was found to have extensive posterior pharyngeal angioedema inconsistent with her relatively benign external examination. This case highlights the typical features of myxedema coma and discusses our necessity for a rescue device in definitive endotracheal tube placement. Emergency physicians should anticipate a potentially difficult airway in all myxedema coma patients regardless of the degree of external facial edema present.

Each year approximately 1 million total hip replacements (THR) are performed worldwide. A percentage of failure due to surgical approach and imprecise implant placement still exists. These result in several serious complications. We propose an approach to plan, to simulate, and to assist prosthesis implantation for difficult cases of THR based on 3-D virtual models, generated by segmenting patients' CT images, 3-D solid models, obtained by rapid prototyping (RP), and virtual procedure simulation. We carried out 8 THR with the aid of 3-D reconstruction and RP. After each procedure a questionnaire was submitted to the surgeon to assess the perceived added value of the technology. In all cases, the surgeon evaluated the 3-D model as useful in order to perform the planning. The clinical results showed a mean increase in the Harris Hip Score of about 42.5 points. The mean time of prototyping was 7.3 hours, (min 3.5 hours, max 9.3 hours). The mean surgery time was 65 minutes (min 50 minutes, max 88 minutes). Our study suggests that meticulous preoperative planning is necessary in front of a great aberration of the joint and in absence of normal anatomical landmarks, CT scan is mandatory, and 3-D reconstruction with solid model is useful.

Tuberculosis involving the central nervous system (CNS) is rarely observed in non immuno-compromised hosts. We report herin the various clinical, biological and radiological manifestations observed in 7 patients with CNS tuberculosis. Clinical and biological records of 7 patients with CNS tuberculosis were retrospectively studied. All patients had encephalic CT-scan and MRI in the course of the disease. 5 women and 2 men with a mean age of 38.4 years initially initially presented with headache (n = 6), fever (n = 5), meningeal irritation (n = 3), localizing neurological signs (n = 1). Lumbar punction revealed lymphocytic meningitis (n = 6/7). Mycobacterium tuberculosis or bovis was isolated in 3 patients only. Cerebral tomodensitography or magnetic resonance imaging were initially normal in most of cases (n = 4/7), but discovered in the course of disease basilar meningitis (n = 6), hydrocephalus (n = 6), abcess or tuberculoma (n = 4). In all the patients, initiation of the treatment was complicated by clinical and/or biological deterioration, called paradoxal reaction, leading in all cases to glucocorticoid adjunction, with various final results. Indeed, 4 patients developed neurological sequelae. No patient died. CNS tuberculosis is a rare disease in non immunocompromised patients whose diagnostic may be difficult due to the absence of specific clinical symptoms, negative initial radiological examination, as well as delayed and often negative bacterial isolation. Paradoxal reaction appeared to be frequent despite specific antibiotherapy and underlines the beneficial effects of addictive corticosteroids.

Intraoperative testing of gastrointestinal anastomosis effectively ensures anastomotic integrity. This study investigated whether the routine use of methylene blue intraoperatively identified leaks to reduce the postoperative proportion of clinical leaks. This study retrospectively analyzed consecutive total gastrectomies performed from January 2007 to December 2014 in a university hospital setting by a general surgical group that exclusively used the methylene blue test. All surgeries were performed for gastric or junctional cancers (n = 198). All reconstructions (Roux-en Y esophagojejunostomy) were performed using a stapler. The methylene blue test was used in 108 cases (group 1) via a nasojejunal tube. No test was performed for the other 90 cases (group 2). Intraoperative leakage rate, postoperative clinical leakage rate, length of hospitalization, and mortality rate were the outcome measures. The intraoperative leakage rate was 7.4% in group 1. The postoperative clinical leakage rate was 8.6%. The postoperative clinical leakage rate was 3.7% in group 1 and 14.4% in group 2 (p = 0.007). There were no postoperative clinical leaks when an intraoperative leak led to concomitant intraoperative repair. The median length of hospital stay was 6 days in group 1 and 8 days in group 2 (p < 0.001). One death occurred in each group. No test-related complications were observed. The methylene blue test for esophagojejunostomy is a safe and reliable method for the assessment of anastomosis integrity, especially in cases with difficult esophagojejunostomic construction.

Risk factors for and management of graft pancreatitis.

2013-02-01

Systematic and detailed analysis of risk factors, pathophysiology, clinical manifestation, diagnosis and management of graft pancreatitis in its different forms, that is acute and chronic graft pancreatitis (A-GP and C-GP), and A-GP being further distinguished into: physiological (P-AGP), early (E-AGP) and late AP (L-AGP). Graft pancreatitis is the second most-frequent complication following pancreas transplantation. P-AGP is an unavoidable entity related to ischemic reperfusion injury. It is usually clinically silent. It is a timely and prognostically self-limited process. E-AGP occurs within 3 months after pancreas transplantation (PTx) in 35% of cases and is associated with high rates of graft loss (78-91%). Clinical signs are pain, systemic inflammatory response (SIRS) and haematuria. Therapy can be medical, interventional and surgical. L-AGP occurs 3 months following PTx in 14-25% of cases and represents an uncommon cause of graft loss. Typical clinical signs are pain, abdominal tenderness and fever. Typical laboratory signs are hyperamylasaemia, hyperglycaemia and hypercreatininaemia. Therapy is usually conservative. C-GP is difficult to be distinguished from chronic rejection and is associated to graft loss in 4-10% of cases. Recurrent A-GPs and infections are the main risk factors. Specific symptoms are chronic abdominal malaise, constipation and recurrence of DM. Isolated hyperglycaemia is typical of C-GP. The therapy is usually conservative. This systematic analysis of different manifestations of graft pancreatitis provides the basis for a clinical approach to tackling this complex entity.

All-time high tularaemia incidence in Norway in 2011: report from the national surveillance.

Tularaemia has mainly been a sporadic disease in Norway. In 2011, 180 persons (3.7 per 100,000 population) were diagnosed with tularaemia. This article describes the epidemiological and clinical features of tularaemia cases during a year with exceptionally high tularaemia incidence. Data from the national reference laboratory for tularaemia combined with epidemiological data from the Norwegian Surveillance System for Communicable Diseases (MSIS) were used. The incidence of tularaemia varied greatly between counties, but almost every county was involved. The majority (77.8 %) of the cases were diagnosed during the autumn and winter months. The geographic distribution also showed seasonal patterns. Overall, oropharyngeal tularaemia (41.1 %) was the most common clinical presentation, followed by glandular (14.4 %), typhoidal (14.4 %), respiratory (13.3 %) and ulceroglandular (12.8 %) tularaemia. From January to April, oropharyngeal tularaemia dominated, from May to September, ulceroglandular tularaemia was most common, whereas from October to December, there was an almost even distribution between several clinical forms of tularaemia. Eighty-five (47.2 %) of all tularaemia cases were admitted to, or seen as outpatients in, hospitals. An unexpectedly high number (3.9 %) of the patients had positive blood culture with Francisella tularensis. The clinical manifestations of tularaemia in Norway in 2011 were diverse, and changing throughout the year. Classification was sometimes difficult due to uncharacteristic symptoms and unknown mode of transmission. In rodent years, tularaemia is an important differential diagnosis to keep in mind at all times of the year for a variety of clinical symptoms.

Fournier's gangrene caused by Actinomyces funkei, Fusobacterium gonidiaformans and Clostridium hathewayi.

We report the first case of Fournier's gangrene caused by three unusual anaerobic organisms: Actinomyces funkei, Fusobacterium gonidiaformans and Clostridium hathewayi. The infection occurred in a 73-year-old man without typical risk factors for the development of Fournier's gangrene. Clinical outcome was good after prolonged antibiotic treatment and extensive debridement of the perineum. The case suggests that A. funkei, F. gonidiaformans and C. hathewayi should be considered as potential pathogens of Fournier's gangrene. Human infections caused by these organisms are very rare but can be underestimated because correct identification is very difficult, especially in polymicrobial infections such as Fournier's gangrene.

Pelvic discontinuity is a rare but serious problem in orthopedic surgery. Acetabular reconstruction in case of severe bone loss after failed total hip arthroplasty is technically difficult, especially in segmental loss type III (anterior or posterior) or pelvic discontinuity (type IV). Acetabular reinforcement devices are frequently used as load-sharing devices to allow allograft incorporation and in order to serve as support of acetabular implants. This study tries to show, by means of biomechanic work, the efficiency of reinforced plate in anterior column in a segmental pelvic loss, illustrated with a clinical case, which shows the socket stability of hip prosthesis. © 2017 Elsevier Ltd.

Primary vascular tumours of bone are rare. Haemangiomas occur as incidental findings in the skull or in the spine. A solitary haemangioma of the hand skeleton is rare and difficult in radiological and histological differential diagnosis. We report a case of a 23 year-old patient presenting with a capillary hemangioma of the left second finger of few months duration for which he underwent amputation. Postoperative evolution was good and showed no recurrence. We discuss this through observation and a review of the literature including the different clinical, radiological and pathological diagnostic problems associated with an unusual site for vascular proliferation.

2011-09-01

Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissue and involve, essentially, the same pathological process. They are usually classified into three main groups: periapical, florid, and focal cemental dysplasias depending on their extent and radiographic appearances. Radiographically, florid cementoosseous dysplasia (FCOD) appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. The best management for the asymptomatic FCOD patient consists of regular recall examinations with prophylaxis. The management of the symptomatic patient is more difficult. A case of FCOD occurring in a 52-year-old edentulous Korean female is reported which is rare with regard to race and sex.

Eosinophilic gastroenteritis is an uncommon condition characterized by focal or diffuse infiltration of eosinophils in the gastrointestinal tract in the absence of secondary causes. The pathogenesis of this condition is not well understood and its clinical presentation depends on the segment and layer of the gastrointestinal tract affected. The definition of eosinophilic gastroenteritis may be difficult, as the normal ranges of eosinophil numbers in normal and abnormal gastric and intestinal mucosa are not standardized. We present the case of a 59-year-old male who came to the hospital with hypovolemic shock and lethargy secondary to severe diarrhea. Laboratory analysis was significant for peripheral eosinophilia, and pathology from both the duodenum and colon showed marked eosinophilic infiltration.

Urologic sequelae of childhood genitourinary trauma and abuse in men: principles of recognition with fifteen case illustrations.

PubMed

McCarty, T; Roberts, L W; Hendrickson, K

1996-05-01

Providing urologic care to men who have been traumatized during childhood may be especially challenging because of the extent, severity, and unusual character of their urogenital problems. Recognition of past trauma entails attentiveness to patients' background and behaviors. As illustrated through these 15 cases, patients who present with too many past surgeries, too many unremitting urologic complaints, too little sexual function and too few genital parts, sexual impulses that are too strong, sexualized conduct in clinical settings, and self-destructive behaviors surrounding sexuality may have experienced trauma in the past. While empirical studies are necessary to demonstrate the ultimate utility of these categories, appreciation of these clinical indications improves the urologic care provided to traumatized men in four ways: by elucidating unusual and unusually recalcitrant urologic complaints, thereby clarifying clinical decisions; by allowing for appropriate use of psychiatric consultation; by promoting a better understanding of the sequelae of trauma in men; and by alleviating the discomfort naturally felt by urologists and their staff when caring for these difficult, multiproblem patients.

Case reports: molar distalization with static repelling magnets. Part II.

PubMed

Steger, E R; Blechman, A M

1995-11-01

The following two nonextraction therapy case reports demonstrate four important points: (1) Static repelling magnets, with certain characteristic parameters, distalize molars rapidly without adverse effects that are clinically discernable. Beneficial properties such as considerably reduced patient compliance requirements for force application, reduced mobility and discomfort, and mostly bodily movement are demonstrated clinically. (2) Anchorage can be controlled by using conventional techniques of anchorage augmentation or force reduction. (3) Treatment can be satisfactorily completed and documented in accord with contemporary criteria, with conventional therapeutic methods, once the initial, most difficult, magnetic molar distalization is completed. (4) The mechanism of action that accounts for the bioeffects remains unclear. However, we hypothesize that observed reduction of mobility and discomfort during rapid movement, combined with basic research and other clinical data, are attributable to the simultaneous, synergistic property of the magnetic force field, which disrupts the local equilibrium and also the static magnetic bioeffect. Among others, one distinguishing and pertinent bioeffect may be an increased rate of osteogenesis and bone remodeling, which may be very dependent on correct dosage through a possible biologic window and the field geometry.

It is to the disadvantage of the doctors in training that there is a decline in the rate of clinical autopsy world wide. This decline may to an extent depend on the attitude of the physicians. To evaluate the attitude of resident doctors towards the practice of clinical autopsy and to determine their role in the decline of clinical autopsy. We carried out a survey of the attitude of resident doctors undergoing training in the various clinical departments of our teaching hospital towards clinical autopsy practice. This survey was by means of a structured randomly distributed questionnaire. Questions were asked on their willingness to request for autopsy, the number of autopsies that they have requested for so far, what hinders them from requesting for autopsy, the level of participation at autopsy and the importance of autopsies in the health care delivery system Eighteen (30%) out of 60 resident doctors attributed their inability to request for autopsy on their not being in direct control of the patients, while 16 (26.7%) found it difficult to get consent from the relatives. Seventeen per cent of them gave reason of not being able to obtain report from the pathologist, 13.3% said it was difficult to get pathologist to perform autopsy on time while only 11% said they knew the diagnosis in most of their cases. Almost all the resident doctors (98.5%) agreed that autopsy is a necessary procedure and is important for their training and health care delivery system Autopsy rate can increase if the resident doctors receive more blessings to request for autopsy from their consultants. Increased exposure to autopsies and education with regards to the benefits of autopsies at both the undergraduate and post graduate level will contribute to improvement in the rate of clinical autopsy.

2013-12-01

The ankle joint can be affected by several diseases, with clinical presentation varying from mild pain or swelling to inability, becoming in some cases a serious problem in daily life activities. Arthroscopy is a widely performed procedure in orthopedic surgery, due to the low invasivity compared to the more traditional open field surgery. The ankle joint presents anatomical specificities, like small space and tangential view that make arthroscopy more difficult. From 2000 more than 600 ankle arthroscopies were performed at our institution. The treated pathologies were mostly impingement syndrome and osteochondral lesions, and in lower percentage instabilities and ankle fractures. In the impingement, the AOFAS scores at FU showed an increase compared to scores collected preoperatively, with improvement of symptoms in most of the cases, good or excellent results in 80 % of cases. In ligament injuries, AOFAS score significatively improved at the maximum follow-up. In fractures all patients had an excellent AOFAS score at maximum follow-up, with complete return to their pre-injury activities. In osteochondral injuries, the clinical results showed a progressive improvement over time with  the different performed procedures. Control MRI and bioptic samples showed a good regeneration of the cartilage and bone tissue in the lesion site. The encouraging obtained clinical results, in line with the literature, show how the arthroscopic technique, after an adequate learning curve, may represent a precious aid for the orthopedic surgeon and for the patient's outcome.

Xanthogranulomatous cystitis (XC) is a very rare chronic benign inflammatory disease of the bladder. It may cause local invasion although it is not a malign lesion and may occur together with malign lesions. It has a clinical importance as the distinction from malign lesions is difficult clinically and pathologically. Sharing a 37-year-old female case with giant XC imitating bladder tumor referring to the hospital with hematuria and stomach ache, together with current literature, we wanted to present that the disease can be treated with bladder-preserving approaches instead of radical approaches even though the mass is big in these cases. Application of basic excision and partial resection for small masses and radical cystectomy for large masses was reported in literature. We think that our case may provide a contribution to literature in treatment approach since we provided surgical cure with partial resection in a big mass with dimensions of 9 cm × 8 cm which is different from the present literature. Even though XC is a rare disease, it should be considered in prediagnosis for especially big dimensioned masses, and treatment should be planned according to the pathology result after together with cystoscopy in suitable patients.

Rumination syndrome is an uncommon gastrointestinal functional disorder that may be difficult to diagnose, as not many physicians are aware of this condition. In many cases, patients undergo numerous tests and are prescribed several treatments based on erroneous diagnoses. When the correct diagnosis is eventually made, therapy for the syndrome can be difficult and complex because of its multifactorial nature. The aim of this study was to present our experience with this condition, by presenting an analysis of the clinical, diagnostic, and therapeutic data of our patients. A prospective and retrospective study was conducted on all cases of rumination syndrome diagnosed between January 2010 and May 2016 in patients attending the Paediatric Gastroenterology Departments of two hospitals: Consorci Sanitari de Terrassa and Hospital Materno-Infantil Vall d'Hebron (Barcelona, Spain). The analysis included 12 patients, with a mean age at the onset of symptoms of 9 years and 1 month, and the mean time period to make the diagnosis was 2 years and 3 months. A mean of 8.1 complementary tests were carried out before establishing the diagnosis. In 10 of the 12 patients, some type of treatment had been given before the diagnosis of rumination syndrome, but was unsuccessful in all cases. Ten of our patients underwent the novel, experimental biofeedback therapy. Due to the limited knowledge of this condition among attending professionals in terms of the clinical presentation, diagnosis, and treatment, patients with rumination syndrome are often misdiagnosed and undergo numerous avoidable complementary tests, and invasive, costly treatments.

Background This study aimed to evaluate the epidemiology, clinical and microbiological features, treatment, and outcomes of infective endocarditis (IE) on the island of Crete, a region with high levels of antimicrobial resistance. Materials and Methods Medical records of all hospitalized patients diagnosed with IE at the University Hospital of Heraklion, Crete, Greece, from 1995 to 2015, were retrospectively reviewed. Patients who met the modified Duke's criteria for definite or possible IE were included. Results A total of 82 IE patients (median age 67 [range 21–86] years) were included. Most patients suffered from left-sided IE (94%), while most cases of infection occurred in native valves (53.6%). Systemic inflammatory response syndrome criteria were lacking in almost half of the patient population. The leading causative microorganism was Staphylococcus aureus, isolated in 24 cases (29%), followed by Streptococcus spp. in 15 (18%) and Enterococcus spp. in 12 (14.5%). A number of rare and difficult to treat microorganisms had been identified, such as Gemella morbillorum in four cases (4.5%), Streptococcus lugdunensis in two (2.5%) and Streptococcus pneumoniae in one (1%). One patient was serologically positive for Coxiella burnetii (1%). All patients received empirical antimicrobial treatment, proven appropriate in 39 blood culture-positive patients (56.5%). Thirteen (16%) patients were classified as culture negative. Seven patients (8.5%) were surgically treated. In-hospital death occurred in 9 patients (11%). Conclusion Changes in IE profile requires continuous epidemiological updates. Staphylococcus and Streptococcus spp. remain the most common etiologic agents. However, the presence of uncommon and/or difficult to treat pathogens raise concerns on the appropriate prophylaxis as well as empirical treatment. PMID:29637749

IgE-blocking therapy for difficult-to-treat asthma: a brief review.

2004-03-01

To review the characteristics of difficult-to-treat asthma and describe patients who may benefit from therapy with the recently approved humanized monoclonal antiimmunoglobulin E (IgE) antibody, omalizumab. Up to 20 percent of patients have difficult-to-treat asthma. These patients consume a disproportionate share of asthma care resources. Clinical and economic outcomes can be improved via improved self-management, increased adherence to prescribed therapy, and better compliance to national asthma treatment guidelines. These patients also may benefit from therapies that directly target mechanisms responsible for persistent airway inflammation and elicit favorable clinical responses. Effective asthma control remains difficult in a small cohort of patients with persistent, severe airway inflammation. Management strategies that improve asthma control and reduce exacerbations can improve clinical outcomes and minimize health care resource utilization.

2016-05-01

Lymphomatoid papulosis (LyP) belongs to the group of cutaneous CD30+ lymphoproliferative disorders. Pseudocarcinomatous hyperplasia has rarely been reported in patients with LyP. In this report, we describe a case of LyP presenting as pseudocarcinomatous hyperplasia. The patient was a 7-year-old girl who presented with a recurrent papulonodular eruption on her face and trunk for 2 months. Histopathologic examination revealed an irregular growth of hyperkeratotic epidermis into the whole dermal layer with marked nests of squamous cells in the background of diffuse atypical lymphoid cells, eosinophils and neutrophils. The large atypical cells were positive for CD30 and CD3, but negative for CD4, CD5, CD8, CD20 and CD56. A TCR-γ clone was identified by polymerase chain reaction (PCR). The correct diagnosis in cases of LyP with overlying pseudocarcinomatous epithelial hyperplasia can be very difficult both clinically and histopathologically. Clinical and histopathologic characteristics should be integrated to avoid an erroneous diagnosis of squamous cell carcinoma or keratoacanthoma. © 2015 John Wiley & Sons A/S.

The aim of this paper is to identify the early and late implications of JPDD for biliary pathology, as well as for endoscopic therapy and classical surgery dealing mainly with lithiasis. This paper is based on a retrospective study comprising a number of 675 ERCP performed on 601 patients between 1997-2007, out of which 399 cases were followed by therapeutic measures. A total of 79 procedures were performed on 65 cases with JPDD. The main criteria were: gender, age, indications regarding the performance of ERCP+/-ES, complications that occurred while carrying out these procedures. In all the cases examined (601) the percentage of JPDD reported was of 10.81%. The rate of complications in the sphincterotomized patients without JPDD was 5.75% and the rate in the sphincterotomized patients with JPDD was 14.89%. In conclusion, the paper discusses the clinical and therapeutic implications of JPDD in biliary pathology. It has been found that JPDD is an important etiological cause for the late diseases occurring after cholelithiasis surgery. JPDD also leads to immediate therapeutic implications such as: difficult cannulation and high incidence of ERCP+/-ES complications.

Case-control studies are appropriate designs in neurology sciences to search for risk factors that have already occurred in a group of patients. In them, the subjects are selected on the basis of whether they have the disease or not and then they are compared in regards to the risk factor or prognosis investigated. These sorts of designs can be performed in a shorter and cheaper way than the regular cohort studies. They are appropriate for the evaluation of rare diseases and can examine multiple etiological factors for a single disease. On the contrary, they are not so efficient when rare exposures are involved. Incidence rates in exposed and non-exposed subjects cannot be calculated and on some occasions, the timing between exposure and outcome can be very difficult to establish. The Odds Ratio and its confident intervals is the measurement used for estimating the risk strength in this design. The clinical neurologist should be familiar with these terms, given the frequency of case-control studies described in neurology science literature, and should know their principal advantages and limitations.

Narcissistic personality disorder (NPD) is characterized by an unrealistic need for admiration, lack of empathy toward others, and feelings of superiority. NPD presents a unique and significant challenge in clinical practice, particularly in medical settings with limited provider contact time, as health professionals treat individuals who often require excessive admiration and have competing treatment needs. This practice review highlights real case examples across three distinct medically oriented clinical settings (inpatient and outpatient behavioral medicine and a Level I trauma center) to demonstrate the difficult and compromising situations that providers face when treating patients with general medical conditions and comorbid narcissistic personality features. The main goal of this article is to discuss the various challenges and obstacles associated with these cases in medical settings and discuss some strategies that may prove successful. A second goal is to bridge diverse conceptualizations of narcissism/NPD through the discussion of theoretical and empirical perspectives that can inform understanding of the clinical examples. Despite differing perspectives regarding the underlying motivation of narcissistic behavior, this practice review highlights that these paradigms can be integrated when sharing the same ultimate goal: to improve delivery of care across medically oriented clinical settings for patients with narcissistic features.

Upper airway abnormalities carry the risk of obstructive sleep apnea (OSA) and difficult tracheal intubations. Both conditions contribute to significant clinical problems and have increased perioperative morbidity and mortality. We hypothesized that patients who presented with difficult intubation would have a very high prevalence of OSA and that those with unexpected difficult intubation may require referral to sleep clinics for polysomnography (PSG). Patients classified as a grade 4 Cormack and Lehane on direct laryngoscopic view, and who required more than two attempts for successful endotracheal intubation, were referred to the study by consultant anesthesiologists at four hospitals. Apnea-hypopnea index (AHI) data and postoperative events were collected. Patients with AHI >5/h were considered positive for OSA. Clinical and PSG variables were compared using t-tests and chi(2) test. Over a 20-mo period, 84 patients with a difficult intubation were referred into the study. Thirty-three patients agreed to participate. Sixty-six percent (22 of 33) had OSA (AHI >5/h). Of the 22 OSA patients, 10 patients (64%) had mild OSA (AHI 5-15), 6 (18%) had moderate OSA (AHI >15/h), and 6 (18%) had severe OSA (AHI >30/h). Of the 33 patients, 11 patients (33%) were recommended for continuous positive airway pressure treatment. Between the OSA group and the non-OSA group, there were significant differences in gender, neck size, and the quality of sleep, but there were no significant differences in age and body mass index. Sixty-six percent of patients with unexpected difficult intubation who consented to undergo a sleep study were diagnosed with OSA by PSG. Patients with difficult intubation are at high risk for OSA and should be screened for signs and symptoms of sleep apnea. Screening for OSA should be considered by referral to a sleep clinic for PSG.

Complex periprosthetic cases are considered as challenges by clinicians. Clinical and radiographic parameters should be considered separately to make the right choice between an endodontically or periodontally compromised treated tooth and implant. Therefore, in order to decide whether the tooth is safe or not, data that have to be collected are specific parameters of both the patient and the clinician. In addition, the presence of periodontal, prosthetic, and orthodontic diseases requires patients to be set in multidisciplinary approach. The aim of this case report is to describe how the multidisciplinary approach could be the best way to manage difficult cases of implant-prosthetic rehabilitation. How to rehabilitate with fixed prosthesis on natural teeth and dental implants a smoker patient who presents with active periodontitis, multiple edentulous areas, dental malocclusion, and severe aesthetic problems was also described.

The aim of this paper is to discuss, through four cases, the characteristics of sinonasal hemangiopericytoma (SNHP) and its diagnostic difficulties. Description of four recent, histologically proven cases of SNHP. Bibliographic research was conducted using the following principal key word: "sinonasal hemangiopericytoma". The four patients complained of non-specific rhino-sinusal symptoms. In each case, physical examination revealed a voluminous unilateral polyploïd tumour of the nasal cavities, documented by CT Scan and MRI. Each patient underwent complete tumour resection by endoscopic sinus surgery. Histological and immunohistochemical examination confirmed SNHP diagnosis, although no specific marker was constantly observed. To date, none of the patients has presented with recurrence. SNHP is of poorly specific clinical and histological presentation. This tumour is difficult to distinguish from solitary fibrous tumour (SFT), with which it is often confused. SNHP is of good prognosis, however lifelong follow-up must be observed.

Abstract Background. Metastatic recurrence after treatment for locoregional cancer is a major cause of morbidity and cancer‐specific mortality. Distinguishing metastatic recurrence from the development of a second primary cancer has important prognostic and therapeutic value and represents a difficult clinical scenario. Advances beyond histopathological comparison are needed. We sought to interrogate the ability of comprehensive genomic profiling (CGP) to aid in distinguishing between these clinical scenarios. Materials and Methods. We identified three prospective cases of recurrent tumors in patients previously treated for localized cancers in which histologic analyses suggested subsequent development of a distinct second primary. Paired samples from the original primary and recurrent tumor were subjected to hybrid capture next‐generation sequencing‐based CGP to identify base pair substitutions, insertions, deletions, copy number alterations (CNA), and chromosomal rearrangements. Genomic profiles between paired samples were compared using previously established statistical clonality assessment software to gauge relatedness beyond global CGP similarities. Results. A high degree of similarity was observed among genomic profiles from morphologically distinct primary and recurrent tumors. Genomic information suggested reclassification as recurrent metastatic disease, and patients received therapy for metastatic disease based on the molecular determination. Conclusions. Our cases demonstrate an important adjunct role for CGP technologies in separating metastatic recurrence from development of a second primary cancer. Larger series are needed to confirm our observations, but comparative CGP may be considered in patients for whom distinguishing metastatic recurrence from a second primary would alter the therapeutic approach. Implications for Practice. Distinguishing a metastatic recurrence from a second primary cancer can represent a difficult clinicopathologic problem but has important prognostic and therapeutic implications. Approaches to aid histologic analysis may improve clinician and pathologist confidence in this increasingly common clinical scenario. Our series provides early support for incorporating paired comprehensive genomic profiling in clinical situations in which determination of metastatic recurrence versus a distinct second primary cancer would influence patient management.

Abstract Clinically significant sellar cysts unrelated to pituitary adenomas are uncommon. Intracranial cholesteatomas are also rare and are most common in the middle ear and mastoid region. We report an even rarer case of cholesteatoma in the sellar region—a challenging diagnosis guided by clinical presentations, radiological signs, and biopsy, aiming at emphasize the importance of considering cholesteatoma when making differential diagnoses of sellar lesions. We present a case of cholesteatoma in the sellar region in a 56-year-old man with hypopituitarism, diabetes insipidus, and cystic imaging findings. It was difficult to make an accurate diagnosis before surgery. We present detailed analysis of the patient's disease course and review pertinent literature. The patient underwent a surgical exploration and tumor resection through a transsphenoidal approach. Pathologic results revealed a cholesteatoma. The patient's symptoms improved a lot after surgery, and the postoperative period was uneventful. Taken together, the lesion's imaging appearance, pathological characteristics, and clinical features were all unique features that lead to a diagnosis of cholesteatoma. As we did not see such reports by Pubmed and EMBASE, we believe this is the first reported case of sellar cholesteatoma presenting in this manner. This article emphasized that cholesteatomas, although rare, should be considered part of the differential diagnosis of sellar lesions. PMID:26962793

Epithelial cyst in an intrapancreatic accessory spleen (ECIPAS) is exceedingly rare with only 57 cases reported since the first publication in 1980. Comprehensive clinical and diagnostic features remain to be clarified. We present a case of ECIPAS in a 21-year-old Philippine woman who was admitted with right upper quadrant abdominal pain. A cystic lesion in the pancreatic tail was discovered and evaluated by computed tomography and magnetic resonance images. Based on clinical and radiological features a solid pseudopapillary neoplasm was suspected. The patient underwent robot-assisted spleen preserving distal pancreatectomy. Pathological evaluation revealed a 26 mm intrapancreatic accessory spleen with a 16 mm cyst, lined by multilayered epithelium in the tail of the pancreas. The postoperative course was uneventful. Differentiating ECIPAS from (pre)malignant cystic pancreatic neoplasms based on clinical and radiological features remains difficult. When typical radiological signs can be combined with scintigraphy using Technetium-99m labelled colloid or Technetium-99m labelled erythrocytes, which can identify the solid component of the lesion as splenic tissue, it should be possible to make the right diagnosis noninvasively. When pancreatectomy is inevitable due to symptoms or patient preference, minimally invasive laparoscopic or robot-assisted spleen preserving distal pancreatectomy should be considered.

As the signs of dehydration often overlap with those of pneumonia, it may be difficult for health workers in resource-poor settings to make a clinical diagnosis of pneumonia in children with dehydration. This issue has received very little attention. To compare the clinical features of pneumonia in children with and without dehydration caused by diarrhoea. All children aged 2-59 months with diarrhoea and radiologically confirmed pneumonia admitted to the Special Care Ward (SCW) of Dhaka Hospital, ICDDR,B between September and December 2007 were enrolled for the study. Children with dehydration (67 cases) and those without (101 controls) were compared. Cases presented less frequently with fast breathing (60% vs 88%, p<0.001) and lower chest-wall indrawing (67% vs 82%, p=0.035) than did controls. In logistic regression analysis, cases more often had severe malnutrition (OR 2.31, CI 1.06-5.02, p=0.035) and cyanosis (OR 19.05, CI 1.94-186.68, p=0.011) and were abnormally sleepy (OR 372, CI 1.71-8.08, p=0.001). Fast breathing and lower chest-wall indrawing may be less reliable for the diagnosis of pneumonia in children with dehydration, especially when there is severe malnutrition.

Food-borne botulism is a disease caused by the ingestion of food contaminated with botulinum toxin, often present in smoked meat, canned food and preserved food; it can occur as sporadic case or as an outbreak. In the last decades there has been an increasing incidence of food-borne botulism in Portugal. The authors do a review of five cases of food-borne botulism, three isolated cases and 2 familiar. Four were associated with the ingestion of smoked ham and one of canned tunafish. The incubation period was 48 hours in one patient and 4 days in another, in the remaining patients it was not possible to determine this period. The clinical picture was dominated in all patients by diplopy, dysphagia, dizziness, blurred vision, dry mouth and constipation, and in two patients there were gastrointestinal complains. In one patient the electromyography findings were compatible with pre-synaptic neuromuscular blockage. A toxin type B was found in the serum of one patient and in the food involved in the two familiar cases. All patients experienced complete recovery with only symptomatic treatment. With this article the authors intend to call attention to this diagnosis, which is not rare, but difficult for someone not familiar with its presentation, being of notice that the diagnosis is essentially clinic with a strong epidemiological history, confirmed by typical electromyography findings and by the identification of the toxin involved. In Portugal there is only descriptions of clinical cases associated with the type B and the type E toxins, not being necessary the resource to the antitoxin therapy.

Spinal cord ischemia (SCI) following endovascular abdominal aortic aneurysm (AAA) repair (EVAR) is a rare but devastating complication. The mechanism underlying the occurrence of SCI following EVAR seems to be multifactorial and is underreported and not fully elucidated. The aim of the study was to investigate the clinical outcomes in patients with this serious complication. A systematic review of the current literature, as per PRISMA statement guidelines, to evaluate the incidence of SCI following elective EVAR was performed. PubMed and Scopus databases were systematically searched. Studies reporting on thoracic endovascular aneurysm repair, open repair of AAAs, and symptomatic or ruptured AAAs were excluded. In total, 18 articles reporting 25 cases were included. The mean age was 74.6 ± 7.6 (range: 60-90) years. The mean diameter of AAAs was 5.96 ± 1.0 cm (range: 4.7-8.3). Six cases also had aneurysms in the common iliac arteries. Seventy-one percent of AAAs had characteristics that made EVAR difficult and technically demanding. The mean operative time was prolonged, 254 ± 104.6 minutes, and associated with extensive intravascular handling. In 41.6% of cases, additional procedures were performed because of the difficult anatomy. Thirty-two percent of the cases had 1 internal iliac artery (IIA) embolized with coils or covered with the stent graft and 14% had both IIAs compromised. In most of the cases, SCI symptoms presented immediately after the operation, and in 14.8% of patients the symptoms had late presentation. Almost all cases had motor loss in the form of paraparesis or paraplegia, 54% of the cases also had diminished sensation, and 29.1% of the cases had urinary and/or fecal incontinence. Heterogeneity was observed regarding the management of the disease; in 6 of the cases cerebrospinal fluid (CSF) drainage was performed, steroids were administered in 5, and in the other cases an expectant strategy was selected. In 50% of the cases, only small improvement was seen at follow-up. In 25% of the cases no improvement was seen, and 25% had almost complete recovery. Our study identified a common pattern among patients who present SCI following EVAR: difficult anatomy, prolonged operative time, additional procedures, and extensive intravascular handling that may have led to embolization. Patency of pelvic circulation preoperatively is also of importance. Regarding outcomes, only 25% of patients recovered, and in certain cases CSF drainage may have significantly improved chances for recovery. Copyright © 2018. Published by Elsevier Inc.

Last year, our pathology informatics fellowship added informatics-based interactive case studies to its existing educational platform of operational and research rotations, clinical conferences, a common core curriculum with an accompanying didactic course, and national meetings. The structure of the informatics case studies was based on the traditional business school case study format. Three different formats were used, varying in length from short, 15-minute scenarios to more formal multiple hour-long case studies. Case studies were presented over the course of three retreats (Fall 2011, Winter 2012, and Spring 2012) and involved both local and visiting faculty and fellows. Both faculty and fellows found the case studies and the retreats educational, valuable, and enjoyable. From this positive feedback, we plan to incorporate the retreats in future academic years as an educational component of our fellowship program. Interactive case studies appear to be valuable in teaching several aspects of pathology informatics that are difficult to teach in more traditional venues (rotations and didactic class sessions). Case studies have become an important component of our fellowship's educational platform.

To explore the clinicopathological characteristics of aspiration pneumonia in the elderly. The clinical data of 30 cases of autopsy-proven aspiration pneumonia in Beijing Hospital from 1973 to 2002 were reviewed. The patients consisted of 28 males and 2 females, aged from 63 to 103 [mean (83 ± 9)] years. Only 15 cases were clinically diagnosed as aspiration pneumonia before death. Concomitant diseases were severe and complex, mostly coronary disease, cerebrovascular disease, hypertension, COPD, and diabetes mellitus. All the patients suffered from at least 3 concomitant diseases. Long-term bedridden and nasogastric feeding was seen in 11 and 17 patients respectively. The clinical presentation and chest X-ray of aspiration pneumonia in the elderly were nonspecific and variable. Mixed infections were common . The main bacteria isolated were Gram-negative bacilli, in particular Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Escherichia coli and Candida albicans. By pathology, macrophages with foreign bodies were found in all the 30 cases and multiple small abscesses were found in 14 cases. The lesions were adjacent to the bronchioles and in the lung tissue around the bronchioles, mostly multi-lobar and bilateral. Unilateral or bilateral pleural effusion developed in 20 patients. The accordance between radiological and pathological diagnosis of aspiration pneumonia was very poor. The foci of infection detected by X-ray were proven by autopsy in 13 patients, while pleural effusions in X-ray were proven by autopsy in 15 patients. Multi-concomitant diseases, mixed infection and extra-pulmonary presentations were common in elderly patients with aspiration pneumonia. Multiple small abscesses were the pathological characteristics of aspiration pneumonia in the aged. A definite clinical diagnosis of aspiration pneumonia was difficult. Recurrent silent microaspiration was a feature of aspiration in the elderly. The assessment of risk factor of aspiration played an important role in the clinical diagnosis of aspiration pneumonia.

The emergence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) infections requires re-assessment of therapeutic choices. Here we report the efficacy of cefoxitin-based antibiotic therapy for ESBL-E prostatitis. A prospective study including patients with ESBL-E prostatitis resistant to trimethoprim/sulfamethoxazole and fluoroquinolones from January 2014 to March 2016 was conducted. Cefoxitin was administered by continuous infusion for 3 weeks in the case of acute bacterial prostatitis or 6 weeks in the case of chronic bacterial prostatitis (CBP), with intravenous fosfomycin for the first 5 days. Urological investigations were performed to diagnose underlying urinary tract pathology. Clinical and microbiological efficacy were evaluated 3 months (M3) and 6 months (M6) after the end of therapy. A total of 23 patients were included in the study. The median patient age was 74 years (range 48-88 years). Of the 23 infections, 14 (61%) were CBP and 12 (52%) were healthcare-associated infections. The bacteria involved were Escherichia coli in 11 cases, Klebsiella pneumoniae in 10 cases and Klebsiella oxytoca in 2 cases. Clinical cure was observed in 19/23 patients (83%) at M3 and in 17/22 patients (77%) at M6. Urocultures were sterile in 13/23 patients (57%) at M3 and in 9/19 patients (47%) and M6. Urinary colonisation was observed in 6/19 patients (32%) with clinical cure at M3 and 5/14 patients (36%) with clinical cure at M6. No resistance to cefoxitin was detected. Surgical treatment was required for 7/23 patients (30%). In conclusion, cefoxitin-based antibiotic therapy is suitable for difficult-to-treat ESBL-E infections such as prostatitis.

Lymphoma of the uterine cervix (LUCX) is rare and may occur as a primary or secondary manifestation of this disease. Clinical and cytological presentations of LUCX vary and establishing diagnosis is often difficult. Surgery followed by radiation or chemotherapy is the mainstay of treatment. We present the case of a 73-year-old woman with recurrent pathological PAP smears of the cervix and a history of chronic lymphatic leukemia 15 years ago. Colposcopy of the cervix showed no acetowhite lesion and a conization was performed. Histology revealed endocervical lymphoid cells, specified as low-malignant B-Non-Hodgkin lymphoma of the cervix based on the expression of CD5, CD20, and CD23, whilst CD10 and cyclin D1 were negative. The diagnosis was confirmed by flow cytometry of peripheral blood. Staging revealed enlarged iliacal, para-aortic, mediastinal, cervical, subclavicular, and inguinal lymph nodes and hepatosplenomegaly. Bone marrow analysis confirmed lymphoid infiltration consistent with B-cell lymphoma. The patient was scheduled for a combined immuno-chemotherapy with obinutuzumab and chlorambucil. In a MEDLINE literature search, 246 cases of LUCX were identified. One hundred and eighty-five cases were primary and 61 cases were secondary manifestations of LUCX. With a mean follow-up time of 38 months, overall survival was 81%. Data in the literature including clinical and histological characteristics of LUCX as well as the clinical management and prognosis are discussed herein. LUCX is rare and has distinct clinical and histological features. LUCX is usually treated with local surgical excision followed by radiotherapy or chemotherapy.

Evidence-based guidance on how best to treat chronic depression is limited. Cognitive Behavioural Analysis System of Psychotherapy (CBASP) has shown some promise with this 'difficult-to-treat' clinical group. This case series was designed to assess the acceptability and utility of this novel treatment in routine clinical practice within the U.K. National Health Service. We offered an open trial of CBASP to a cohort of 115 referred patients within primary and secondary care. Diagnostic interview and standardised outcome measures were administered before and after 6 months of CBASP with a trained, accredited therapist. Seventy-four patients entered therapy, with 46 completing. 30% met criteria for remission (≤ 8 HRSD-24 score) and a further 30% met criteria for clinically significant change (> 8 and ≤15 HRSD-24 plus 50% reduction in baseline score). Thirty-nine per cent made "No change". Group measures of quality of life, social functioning and interpersonal functioning also improved. This was an open study design with a moderate sample size and no control group. Ratings were not completed using a blinded procedure. CBASP is an acceptable therapy for a large proportion of patients with chronic depression and was associated with clinically significant change in 60% of completers. © 2013 Published by Elsevier B.V.

Overview of clinical research design.

PubMed

Hartung, Daniel M; Touchette, Daniel

2009-02-15

Basic concepts and terminology of clinical research design are presented for new clinical investigators. Clinical research, research involving human subjects, can be described as either observational or experimental. The findings of all clinical research can be threatened by issues of bias and confounding. Biases are systematic errors in how study subjects are selected or measured, which result in false inferences. Confounding is a distortion in findings that is attributable to mixing variable effects. Uncontrolled observation research is generally more prone to bias and confounding than experimental research. Observational research includes designs such as the cohort study, case-control study, and cross-sectional study, while experimental research typically involves a randomized controlled trial (RCT). The cohort study, which includes the RCT, defines subject allocation on the basis of exposure interest (e.g., drug, disease-management program) and follows the patients to assess the outcomes. The case-control study uses the primary outcome of interest (e.g., adverse event) to define subject allocation, and different exposures are assessed in a retrospective manner. Cross-sectional research evaluates both exposure and outcome concurrently. Each of these design methods possesses different strengths and weaknesses in answering research questions, as well as underlying many study subtypes. While experimental research is the strongest method for establishing causality, it can be difficult to accomplish under many scenarios. Observational clinical research offers many design alternatives that may be appropriate if planned and executed carefully.

Tickborne rickettsial diseases (TBRD) continue to cause severe illness and death in otherwise healthy adults and children, despite the availability of low cost, effective antimicrobial therapy. The greatest challenge to clinicians is the difficult diagnostic dilemma posed by these infections early in their clinical course, when antibiotic therapy is most effective. Early signs and symptoms of these illnesses are notoriously nonspecific or mimic benign viral illnesses, making diagnosis difficult. In October 2004, CDC's Viral and Rickettsial Zoonoses Branch, in consultation with 11 clinical and academic specialists of Rocky Mountain spotted fever, human granulocytotropic anaplasmosis, and human monocytotropic ehrlichiosis, developed guidelines to address the need for a consolidated source for the diagnosis and management of TBRD. The preparers focused on the practical aspects of epidemiology, clinical assessment, treatment, and laboratory diagnosis of TBRD. This report will assist clinicians and other health-care and public health professionals to 1) recognize epidemiologic features and clinical manifestations of TBRD, 2) develop a differential diagnosis that includes and ranks TBRD, 3) understand that the recommendations for doxycycline are the treatment of choice for both adults and children, 4) understand that early empiric antibiotic therapy can prevent severe morbidity and death, and 5) report suspect or confirmed cases of TBRD to local public health authorities to assist them with control measures and public health education efforts.

Ischemic colitis and large bowel infarction: a case report.

Ischemic bowel disease results from an acute or chronic drop in the blood supply to the bowel and may have various clinical presentations, such as intestinal angina, ischemic colitis or intestinal infarction. Elderly patients with systemic atherosclerosis who are symptomatic for the disease in two or more vascular beds have multiple comorbidities and are particularly at risk. The clinical evolution and outcome of this disease are difficult to predict because of its pleomorphic aspects and the general lack of statistical data. In this paper, we present the case of a patient who was monitored in our unit for six years. For this patient, we encountered iterative changes in the clinical pattern, beginning with chronic "intestinal angina" and finishing with signs of acute mesenteric ischemia after an episode of ischemic colitis. This evolution is particularly rare in clinical practice, and the case is instructive because it raises discussions about the natural history of the condition and the therapeutic decisions that should be made at every stage of the disease. An important lesson is that ischemic bowel disease should always be considered in patients who have multiple risk factors for atherosclerosis and have experienced recurrent "indistinct" abdominal symptoms. In these cases, aggressive investigation and therapeutic decisions must be taken whenever possible. Despite an absence of standardized protocols, angiographic evaluation and revascularization procedures have beneficial outcomes. Current advances in endovascular therapy, such as percutaneous transluminal angioplasty with stenting, should be increasingly used in patients with chronic mesenteric ischemia. Such therapy can avoid the risks that are associated with open repair. However, technical difficulties, especially in severe stenotic lesions, frequently occur.

We report a well-documented case of paraganglioma involving right ovary, which was initially misdiagnosed as a Sertoli-Leydig cell tumor and recurred one year later. The right ovarian tumor measured 105x90x60 mm and was associated to a subdiaphragmatic tumor measuring 80x60x35 mm, a peritoneal and a preureteral nodules measuring 10 mm either. Microscopically, tumor cells were arranged in trabeculae and cords separated by a delicate stroma. Their cytoplasm was abundant granular and eosinophilic. Their nuclei were enlarged and regular in size with coarse chromatine and a large nucleolus. The tumor expressed neuroendocrine markers (chromogranin, synaptophysin) epithelial membrane antigen and focally cytokeratin 7 and E-cadherin. Pathological ovarian paraganglioma diagnosis could be difficult but one should be aware of its bona fide existence. The clinical course is favourable in most of the cases.

The clinical manifestations, laboratory findings, and survival times of 10 horses with orbital neoplasms are reported. In all cases, orbital neoplasms were malignant and locally invasive with no defined surgical circumscribed edges. It was often difficult to identify the primary cell type of the neoplasia in histologic specimens due to the poorly differentiated, anaplastic nature of the majority of cases. All except one horse were eventually euthanized 2 mo to 5 y after diagnosis due to poor response to treatment, metastasis, or unrelenting orbital neoplasia. Mean survival time increased with surgical treatment, but no significant difference was found among no treatment, chemotherapy, surgical mass removal, or exenteration/enucleation. Equine practitioners should be aware of the marked difference in prognosis of orbital neoplasms compared with ocular or localized eyelid neoplasia. Images Figure 1. Figure 2. Figure 3. PMID:10769765

Custom-made Stent Grafts for the Treatment of Pseudoaneurysms after Childhood Coarctation Surgery.

 Post-coarctation of the aorta (CoA) pseudoaneurysms is a complication of open repair. Thoracic endovascular repair (TEVAR) is feasible but complicated by proximity to the supra-aortic trunks and severe arch angulation.  We describe three cases of post-CoA pseudoaneurysms treated with custom-made Relay stent grafts (Vascutek, Scotland).  Technical and clinical success was achieved in all three cases with no mortality, morbidity, endoleaks, or complications. In all three, pseudoaneurysm sac shrinkage was observed at the follow-ups; in one case, there was complete resolution.  Redo open surgery is challenging because of adhesions of the thoracic cavity and associated morbidity and mortality. TEVAR is less invasive and offers fewer complications. Custom-made modifications overcome difficult anatomies including short landing zones and diameter variability.

Antero mediastinal retrosternal goiter: surgical excision by combined cervical and hybrid robot-assisted approach

PubMed Central

Cicalese, Marcellino; Scaramuzzi, Roberto; Di Natale, Davide; Curcio, Carlo

2018-01-01

Most intrathoracic goiters are located in the anterior mediastinum. Surgical resection is usually recommended in case of morbidity associated with the goiter’s mass effect or for suspicion of malignancy difficult to diagnose without resection. Intrathoracic goiters are usually resected through a cervical approach, with sternotomy needed in selected cases. We report a case of antero mediastinal retrosternal goiter in old age patient undergoing surgical excision by combined cervical and hybrid robot-assisted approach. All steps of the thoracic procedure were completely performed using the da Vinci robot system with final extension of a port-site incision to extract the specimen. This approach provides more advantages than sternotomy regarding post operative clinical benefits and allows a more accurate surgical resection in the antero-superior mediastinum than conventional thoracoscopy.

To confirm the safety and effectiveness of techniques to assist radiofrequency ablation (RFA) for difficult cases, we retrospectively evaluated successful treatment rates, early complications and local tumor progressions. Between June 1999 and April 2009, a total of 341 patients with 535 nodules were treated as difficult cases. Artificial pleural effusion assisted ablation was performed on 64 patients with 82 nodules. Artificial ascites-assisted ablation was performed on 11 patients with 13 nodules. Cooling by endoscopic nasobiliary drainage (ENBD) tube-assisted ablation was performed on 6 patients with 8 nodules. When the tumors were not well visualized with conventional B-mode ultrasonography (US), contrast-enhanced US-assisted ablation with Levovist or Sonazoid or virtual CT sonography-assisted ablation was performed. Contrast-enhanced US-assisted ablation was performed on 139 patients with 224 nodules and virtual CT sonography-assisted ablation was performed on 121 patients with 209 nodules. In total, complete ablation was achieved in 514 of 535 (96%) nodules in difficult cases. For RFA with artificial pleural effusion, artificial ascites and ENBD, complete response was confirmed in all cases. For contrast-enhanced US- and CT sonography-assisted ablation, complete response was 95%. Early complications were recognized in 24 cases (4.5%). All cases recovered with no invasive treatment. Local tumor recurrence was investigated in 377 nodules of 245 patients, and 69 (18%) nodules were positive. Tumor recurrences in each assisted technique were 14.7% in artificial pleural effusion cases, 7% in artificial ascites, 12.5% in ENBD tube cases, 31% in virtual CT sonography, and 8.5% in contrast-enhanced US. Although local tumor progression needs to be carefully monitored, assisted techniques of RFA for difficult cases are well tolerated and expand the indications of RFA. Copyright (c) 2010 S.

Kim, Min-Beom; Boo, Sung Hyun; Ban, Jae Ho

2013-01-01

We aimed to investigate the clinical courses and common nystagmus of isolated vertigo patients with vertebrobasilar stroke. The patients who presented with isolated acute spontaneous vertigo with spontaneous nystagmus (acute vestibular syndrome) at the Emergency Department were retrospectively analyzed. They were referred to the Otolaryngology Department due to the absence of neurologic signs or even of imaging abnormalities after the initial examination at the Emergency Department. Various clinical features, including presenting symptoms, delayed neurologic signs, the site of infarction, and videonystagmographic (VNG) findings were analyzed. Of the 468 cases of acute vestibular syndrome, 23 (4.9%) cases of radiologically proven vertebrobasilar stroke were identified. Of the 23 patients, 17 (74%) showed aggravation of vertigo or delayed neurologic signs during the admission. In the analysis of VNG, 11 (48%) cases of direction-changing gaze-evoked nystagmus, 7 (30%) cases of fixation failure in the caloric test, 6 (27%) cases of periodic alternating nystagmus, and 4 (17%) cases of atypical head-shaking nystagmus were presented. Stroke occurred in the cerebellum (n=18, 78%), medulla (n=4, 17%), and pons (n=1, 4%). In the early stage of vertebrobasilar stroke, an accurate diagnosis was difficult in the Emergency Department even though a radiologic study was performed, but various VNG abnormalities and delayed neurologic signs could help to diagnose whether the origin is central or not.

Laparoscopic cholecystectomy (LC) is very commonly performed surgical intervention. Acute or chronic cholecystitis, adhesions due to previous upper abdomen surgeries, Mirrizi's syndrome and obesity are common clinical conditions that can be associated with difficult cholecystectomy. In this study, we evaluated and scored the patients with difficult surgical exploration during laparoscopic cholecystectomy. All patients who underwent LC from 2010 to 2015 were retrospectively rewieved. According to intraoperative findings DLC cases were described and classified. Class I difficulty: Adhesion of omentum majus, transverse colon, duodenum to the fundus of the gallbladder. Class II difficulty: Adhesions in Calot's triangle and difficulty in dissection of cystic artery and cystic duct Class III difficulty: Difficulty in dissection of gallbladder bed (scleroathrophic gallbladder, hemorrhage from liver during dissection of gallbladder, chirotic liver). Class IV difficulty: Difficulty in exploration of gallbladder due to intraabdominal adhesions including technical problems. A total of 146 patients were operated with DLC. The most common difficulty type was Class I difficulty (88 patients/60.2%). Laparoscopic cholecystectomy was converted to laparotomy in 98 patients. Operation time was found to be related with conversion to open surgery (P<0.05). Wound infection rate was also statistically higher in conversion group (P<0.05). The opertion time was found to be longest with Class II difficulty. Conversion rate to open surgery was also highest with Class II difficulty group. Class II difficulty characterized by severe adhesions in calot's triangle is most serious problem among all DLC cases. They have longer operation time and higher conversion rate.

As a result of right ventricular outflow tract reconstruction, which is the important and basic step of complex cardiac surgery, the blood flow of right ventricular outflow tract is unobstructed, while pulmonary valve regurgitation and right heart dysfunction could be happened. These problems are often ignored in early days, more and more cases of right heart dysfunction need clinical intervention, which is quite difficult and less effective. How to protect effectively the right ventricular function is the focus. At present main methods to protect the right ventricular function include trying to avoid or reduce length of right ventricular incision, reserving or rebuilding the function of the pulmonary valve, using growth potential material for surgery. The protection of the right ventricular function is a systemic project, it involves many aspects, single measures is difficult to provide complete protection, only the comprehensive use of various protection strategy, can help to improve the long-term prognosis.

"Difficult" Colorectal Polyps - Therapeutic Approach.

PubMed

Alecu, M; Simion, L; Ionescu, S; Brătucu, E; Straja, N D

2015-01-01

Endoscopic polypectomy is the gold standard in the treatment of colorectal polyps. The importance of polypectomy rests primarily on the fact that polyp-type lesions present a high risk of malignant degeneration, colorectal polyps being able, if left unattended therapeutically, to generate a colorectal cancer (CRC) - a lesion with a far more negative prognosis. Although preferable, endoscopic polypectomy of colorectal polyps is not always possible, multiple factors generating difficulties in performing this therapeutic measure. We performed a retrospective study in the First Surgical Clinic of the "Prof. Dr. Alexandu Trestioreanu" Bucharest Oncology Institute, spanning a period of 3 years (2008-2011), in which time 224 patients were diagnosed by colonoscopy with colorectal polyps, of whom 222 patients benefited from endoscopic polypectomy. The aim of the study was to identify "difficult" polyps and to identify the criteria for endoscopic surgery versus classic surgery as a therapeutic indication. Presence of "difficult" polyps was observed in 37.56% of the patients diagnosed with colorectal polyps. In over 88% of cases endoscopic polypectomy was possible, and for the remaining patients classic surgery was the therapeutic solution opted for. Presence of "difficult" polyps generates inconveniences in performing endoscopic polypectomy, increasing the risk of postoperative complication occurrence, as well as the duration of the operation. If the criteria for characterizing polyps as "difficult" are relatively well-established, the choice between endoscopic and classic surgery as a therapeutic measure is left at the free will of the operating surgeon, with the exception of situations in which classic surgery is resorted to for oncological reasons.

Endoscopic full-thickness resection (EFTR) is a novel treatment of colorectal lesions not amenable to conventional endoscopic resection. The aim of this prospective multicentre study was to assess the efficacy and safety of the full-thickness resection device. 181 patients were recruited in 9 centres with the indication of difficult adenomas (non-lifting and/or at difficult locations), early cancers and subepithelial tumours (SET). Primary endpoint was complete en bloc and R0 resection. EFTR was technically successful in 89.5%, R0 resection rate was 76.9%. In 127 patients with difficult adenomas and benign histology, R0 resection rate was 77.7%. In 14 cases, lesions harboured unsuspected cancer, another 15 lesions were primarily known as cancers. Of these 29 cases, R0 resection was achieved in 72.4%; 8 further cases had deep submucosal infiltration >1000 µm. Therefore, curative resection could only be achieved in 13/29 (44.8%). In the subgroup with SET (n=23), R0 resection rate was 87.0%. In general, R0 resection rate was higher with lesions ≤2 cm vs >2 cm (81.2% vs 58.1%, p=0.0038). Adverse event rate was 9.9% with a 2.2% rate of emergency surgery. Three-month follow-up was available from 154 cases and recurrent/residual tumour was evident in 15.3%. EFTR has a reasonable technical efficacy especially in lesions ≤2 cm with acceptable complication rates. Curative resection rate for early cancers was too low to recommend its primary use in this indication. Further comparative studies have to show the clinical value and long-term outcome of EFTR in benign colorectal lesions.

Sexuality and physical intimacy in long-term care.

Lichtenberg, Peter A

2014-01-01

Sexuality and sexual needs in older adults remains a neglected area of clinical intervention, particularly so in long-term care settings. Because older adults in medical rehabilitation and long-term care beds present with significant frailties, and often significant neurocognitive disorders, it makes it difficult for occupational therapists and other staff to evaluate the capacity of an older adult resident to participate in sexual relationships. The current paper reviews the current literature on sexuality and aging, examines some of the clinical practices and guidelines regarding sexual expression in long-term care, and presents two case examples. A semistructured interview and decision tree is presented to assist therapists in making careful and informed decisions and thereby balancing the needs for protection with the needs for autonomy.

Paragangliomas are benign neuroendocrine tumors derived from the glomus cells of the vegetative nervous system. Typically, they are located in the region of the jugular bulb and middle ear. The optimal management is controversial and can include surgical excision, stereotactic radiosurgery and embolization. We report the endovascular approach to three patients harboring glomus jugulare paragangliomas. In all cases incomplete occlusion of the lesions was achieved and recanalization in the follow-up period was revealed. Two patients presented no clinical improvement and the remaining one experienced a transient withdrawal of tinnitus. It is technically difficult to achieve complete obliteration of glomus jugulare tumors with the use of embolization and the subtotal occlusion poses a high risk of revascularization and is not beneficial in terms of alleviating clinical symptoms.

Renal ectopia in the rare condition of associated abdominal aortic aneurysm presents a difficult clinical challenge with respect to access to the aorto-iliac segment and preservation of renal function because of its anomalous renal arterial anatomy and inevitable renal ischemia at the time of open repair. Multiple operative techniques are described throughout the literature to cope with both problems. We report a case of a 57-year-old male with an aorto-iliac aneurysm and a congenital solitary pelvic kidney successfully treated by hybrid total renal revascularization using iliorenal bypass followed by unilateral internal iliac artery coil embolization and conventional endovascular aortic aneurysm repair without any clinical evidence of renal impairment.

Revisioning Fordham's 'Defences of the self' in light of modern relational theory and contemporary neuroscience.

PubMed

Kalsched, Donald E

2015-09-01

This paper explores the evolution of Michael Fordham's ideas concerning 'defences of the self', including his application of this concept to a group of 'difficult' adult patients in his famous 1974 paper by the same name. After tracing the relevance of Fordham's ideas to my own discovery of a 'self-care system' in the psychological material of early trauma patients (Kalsched ), I describe how Fordham's seminal notions might be revisioned in light of contemporary relational theory as well as early attachment theory and affective neuroscience. These revisionings involve an awareness that the severe woundings of early unremembered trauma are not transformable through interpretation but will inevitably be repeated in the transference, leading to mutual 'enactments' between the analytic partners and, hopefully, to a new outcome. A clinical example of one such mutual enactment between the author and his patient is provided. The paper concludes with reflections on the clinical implications of this difficult case and what it means to become a 'real person' to our patients. Finally, Jung's alchemical views on transference are shown to be useful analogies in our understanding of the necessary mutuality in the healing process with these patients. © 2015, The Society of Analytical Psychology.

One size does not fit all: distal radioulnar joint dysfunction after volar locking plate fixation.

PubMed

Jones, Christopher W; Lawson, Richard D

2014-02-01

Background Fractures of the distal radius are among the most common injuries treated by orthopedic surgeons worldwide. Failure to restore distal radius alignment can lead to fracture malunion and poor clinical outcomes, including distal radioulnar joint (DRUJ) instability and limitation of motion. Case Description We present a unique case of DRUJ dysfunction following volar plate fixation of bilateral distal radius fractures and analyze the biomechanical causes of this complication. As a result of a relatively excessive tilt of the precontoured locking plate (in comparison to the patient's particular anatomy), the fracture on one side was "over-reduced," disrupting the biomechanics of the DRUJ, causing a supination block. Clinical Relevance Volar locking plates are not a panacea to all distal radius fractures. Plate selection and fixation technique must include consideration of patient anatomy. Robust plates offer the advantage of providing rigid fixation but can be difficult to contour when reconstructing normal anatomy. Restoration of patient-specific anatomy is crucial to the management of distal radius fractures.

Use of cyanoacrylate glue for temporary tarsorrhaphy in children.

2014-01-01

Congenital anophthalmia and postenucleation socket contracture are difficult conditions that require serial socket expansion with the use of hydrogel expanders and custom-made conformers along with temporary tarsorrhaphy. The authors undertook a part prospective case review of all children undergoing temporary tarsorrhaphy using cyanoacrylate glue over a 3-year period at a tertiary specialist children's hospital. They report a series of 7 children undergoing temporary tarsorrhaphy with cyanoacrylate glue instead of the conventional suturing technique. Indications were socket expansion (n = 4), fornix deepening (n = 2), prosthesis reposition, and prolapsed conjunctiva following enucleation (n = 1).The age range was 3 weeks to 14 years (mean, 2.7 years). The glue tarsorrhaphy lasted between 0.5 and 13 weeks (mean, 4.5 weeks). There were no adverse outcomes, and the glue tarsorrhaphy was tolerated well in all cases, with relative ease of reapplication of glue in clinic. Their study demonstrates that this technique allows quick and efficient temporary tarsorrhaphy with relative ease of reapplication in a clinic setting, avoiding the need for multiple general anesthetics.

Soft tissue-based surgical techniques for treatment of posterior shoulder instability.

PubMed

Castagna, Alessandro; Conti, Marco; Garofalo, Raffaele

2017-01-01

Posterior shoulder instability is a rare clinical condition that encompasses different degrees of severity including various possible pathologies involving the labrum, capsule, bony lesions, and even locked posterior dislocation. When focusing on soft tissue involvement, the diagnosis of posterior instability may be difficult to make because frequently patients report vague symptoms not associated with a clear history of traumatic shoulder dislocation. Pathological soft tissue conditions associated with posterior instability in most cases are related to posterior labral tear and/or posterior capsular detensioning/tear. The diagnosis can be facilitated by physical examination using specific clinical tests (i. e., jerk test, Kim test, and reinterpreted O'Brien test) together with appropriate imaging studies (i. e., magnetic resonance arthrography). Arthroscopy may help in a complete evaluation of the joint and allows for the treatment of soft tissue lesions in posterior instability. Caution is warranted in the case of concomitant posterior glenoid chondral defect as a potential cause of poor outcome after soft tissue repair in posterior instability.

A rare combination of thrombotic thrombocytopenic purpura and antiphospholipid syndrome.

: Thrombocytopenia, in the setting of microangiopathic hemolytic anemia and thrombotic events, is characteristic of both thrombotic thrombocytopenic purpura and primary antiphospholipid syndrome. Clinically, it is difficult to distinguish between these two syndromes. We present a 41-year-old woman with chronic, relapsing thrombotic thrombocytopenic purpura in the presence of antiphospholipid antibodies. She had clinical manifestations of antiphospholipid syndrome without meeting laboratory criteria of the Sydney classification system. In the literature, there have only been nine cases of thrombotic thrombocytopenic purpura associated with primary antiphospholipid syndrome. Seven of the nine cases suffered from one or multiple strokes, a common feature in antiphospholipid syndrome, but an uncommon finding in thrombotic thrombocytopenic purpura. We introduce the possibility of an association between thrombotic thrombocytopenic purpura and the presence of antiphospholipid antibodies. Systematic testing of ADAMTS13 activity and anti-ADAMTS13 antibodies in patients who present with neurological symptoms and thrombocytopenia, in the presence of antiphospholipid antibodies, may help with the diagnosis of the rare thrombotic thrombocytopenic purpura-antiphospholipid syndrome combination.

CSF HIV escape is a recently recognised phenomenon that suggests that despite suppressive treatment, HIV RNA may be detected in the CNS compartment in some individuals. In rare cases this is associated with clinical neurological disease, while in most cases, neurological consequences are not apparent. Attempts at characterising the biological substrates of CSF escape and further investigating the neurological consequences need to be made to better understand the implications of this condition for the HIV cure agenda as well as for clinical outcomes. The Global CSF HIV-1 Escape Consortium meeting, convened by the US National Institute of Mental Health, was a first step to gather investigators from diverse sites to discuss opportunities for future collaborative work on this emerging issue. To better understand CSF HIV escape and allow cross-site data reconciliation, it will be useful to reach a consensus set of definitions of the distinct forms of CSF escape, without which concerted cross-site efforts are difficult.

Limb salvage in fungal osteomyelitis of the post-traumatic lower extremity represents a difficult clinical problem requiring aggressive management. We report lower extremity salvage by radical bony debridement, free tissue transfer, distraction osteogenesis with bone-docking, and a novel antifungal regimen in a clinical setting of infection with Scedosporium inflatum, historically requiring amputation in 100% of cases. We treated Scedosporium inflatum osteomyelitis of the tibia and calcaneus with radical debridement of infected bone, free partial medial rectus abdominis muscle flap coverage, transport distraction osteogenesis, and combination voriconazole/terbinafine chemotherapy, a novel antifungal regimen. We achieved successful control of the infection, limb salvage, and an excellent functional outcome through aggressive debridement of infected bone and soft tissue, elimination of dead space within the bony defect, the robust perfusion provided by the free flap, the hypervascular state induced by distraction osteogenesis, and the synergism of the novel antifungal regimen.

Diarrhoea in the enterally fed patient

PubMed Central

Bowling, T E

2010-01-01

Diarrhoea complicating enteral feeding is very common in all clinical settings. The major risk factor is the use of concomitant antibiotics. The underlying mechanisms for the diarrhoea mainly relate to alterations in the colonic flora and physiological responses to the mode of feed delivery although a clear understanding of what is actually happening in vivo remains elusive. Management of diarrhoea includes rationalising medications, excluding relevant comorbidity and using antidiarrhoeal medications. Altering the method and site of feed delivery—for example, continuous to bolus, gastric to postpyloric—can also be tried in the more difficult cases. PMID:28839565

Family relationships of adults with borderline personality disorder.

Allen, D M; Farmer, R G

1996-01-01

Current, ongoing interactions between adults exhibiting borderline personality disorder (BPD) traits and their families of origin may influence and maintain self-destructive behavior. Family interactions in such patients are often characterized by coexisting extremes of overinvolvement and underinvolvement by parental figures. Such parental behavior may trigger preexisting role relationship schemata in vulnerable individuals. Negative family reactions to new behavior patterns may make change difficult. A model for how present-day interpersonal patterns lead to self-destructive behavior, based on clinical observations, is proposed and case examples are presented.

2013-08-01

This article outlines artifactual findings commonly encountered in neuroradiologic MRI studies and offers clues to differentiate them from true pathology on the basis of their physical properties. Basic MR physics concepts are used to shed light on the causes of these artifacts. MRI is one of the most commonly used techniques in neuroradiology. Unfortunately, MRI is prone to image distortion and artifacts that can be difficult to identify. Using the provided case illustrations, practical clues, and relevant physical applications, radiologists may devise algorithms to troubleshoot these artifacts.

Organic brain syndrome. The psychiatric imposter.

Dubin, W R; Weiss, K J; Zeccardi, J A

1983-01-07

Rapid differentiation of organic brain syndrome (OBS) from functional psychiatric illness can be difficult when patients come to an emergency department with predominantly psychiatric symptoms. Using four screening criteria-disorientation, abnormal vital signs, clouded consciousness, and patients older than 40 years with no previous psychiatric history-we detected 38 cases of OBS from 1,140 medically cleared patients. Twelve of these patients were subsequently admitted to a medical unit. Despite the presence of striking behavioral aberration, an increased awareness of the clinical manifestations of OBS will enhance the physician's ability to discriminate OBS from other psychiatric illness.

The clinical and endocrinological findings in 24 children with septo-optic dysplasia and/or agenesis of the corpus callosum are described with particular reference to posterior pituitary function. Nine had diabetes insipidus. The prevalence of diabetes insipidus was similar in children with complete and incomplete forms of septo-optic dysplasia. Maintenance of normal osmotic balance was very difficult in six of these children, even after the introduction of treatment with vasopressin, either as desmopressin, or lysine vasopressin spray in one of the early cases.

Melioidosis is a severe disease that can be difficult to diagnose because of its diverse clinical manifestations and a lack of adequate diagnostic capabilities for suspected cases. There is broad interest in improving detection and diagnosis of this disease not only in melioidosis-endemic regions but also outside these regions because melioidosis may be underreported and poses a potential bioterrorism challenge for public health authorities. Therefore, a workshop of academic, government, and private sector personnel from around the world was convened to discuss the current state of melioidosis diagnostics, diagnostic needs, and future directions.

Current Topics on Salvage Thoracic Surgery in Patients with Primary Lung Cancer.

PubMed

Uramoto, Hidetaka

2016-01-01

Salvage primary tumor resection is sometimes considered for isolated local failures after definitive chemoradiation, urgent matters, such as hemoptysis (palliative intent), and in cases judged to be contraindicated for chemotherapy or definite radiation due to severe comorbidities, despite an initial clinical diagnosis of stage III or IV disease. However, salvage surgery is generally considered to be technically more difficult, with a potentially higher morbidity. This review discusses the current topics on salvage thoracic surgery such as the definition of salvage surgery and its outcome, and future perspectives.

Obstacles to oedipal passion.

PubMed

Kulish, Nancy

2011-01-01

Many new theoretical and technical developments have extended our understandings of triangular conflicts in the psychoanalytic setting. Yet until recently psychoanalysis has lacked theoretical concepts for passion and, most particularly, for oedipal passion. Contemporary psychoanalytic understandings of the nature of oedipal passion help explain why it is both difficult to articulate and why it continues to be "forgotten". The author argues that individual resistances to oedipal passions reappear and are reinforced in collective theories that distance us from oedipal issues. She presents two clinical cases that illustrate enactments around, and resistances to, oedipal passions within both analyst and patient.

Only 3 cases of infective endocarditis (IE) due to methicillin-resistant Staphylococcus haemolyticus (MRSH) have been reported in English literature. Here we report 4 cases of IE due to MRSH encountered in a single university hospital. Population analysis of the strains was performed to assess the presence of vancomycin/teicoplanin heteroresistant subpopulations. Pulsed-field gel electrophoresis was used for molecular typing of isolates. IE was defined in 3 cases as health care associated, and in 1 case, as community acquired. A causative strain was lost. Two strains were heteroresistant to teicoplanin, and 1 also to vancomycin. Genome macrorestriction profile studies demonstrated that 2 MRSH isolates belonged to clones A and E, possessing a class C1 mecDNA, whereas 1 clone was sporadic. All patients were treated with vancomycin plus rifampin. Two patients were cured with antibiotic therapy alone, 1 patient needed surgery, and 1 patient died. Methicillin-resistant multiresistant S. haemolyticus may represent a difficult-to-treat cause of both community and nosocomially acquired IE.

Sepsis is a life-threatening systemic condition that appears to be increasing in the obstetric population. Clinical detection can be difficult and may result in increased morbidity via delays in the continuum of patient care. To describe the burden of severe maternal morbidity (SMM) caused by sepsis in New Zealand and investigate the potential preventability. A multidisciplinary expert review panel was established to review cases of obstetric sepsis admitted to intensive care or high-dependency units over an 18 month span in New Zealand. Cases were then analysed for the characteristics of infection and their preventability. Fifty cases met the inclusion criteria, most commonly due to uterine, respiratory or kidney infection. Fifty per cent (25) of these cases were deemed potentially preventable, predominantly due to delays in diagnosis and treatment. A high index of suspicion, development of early recognition systems and multi-disciplinary training are recommended to decrease preventable cases of maternal sepsis. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Epstein-Barr virus (EBV) plays an important role in various diseases. EBV-associated lymphoproliferative disease (LPD) is a rare disease with a canceration tendency. It is difficult to differentiate LPD with involvement of digestive tract from Crohn disease due to similar clinical and endoscopic manifestations. We present a case report of multiple ulcers with esophagus, small bowel and the entire colon involved, proved to be NK-Cell LPD, developed into EBV-associated NK/T Cell lymphoma, in an immunocompetent man who was initially misdiagnosed as Crohn disease.This report underscores that intestinal ulcers should be cautiously diagnosed, for it sometimes could be a precancerous lesion.

Can pharmaco-electroencephalography help improve survival of central nervous system drugs in early clinical development?

PubMed

2014-03-01

Pharmaco-electroencephalography has significant yet unrealised promise as a translatable intermediate biomarker of central pharmacodynamic activity that could help reduce Phase 2 attrition in the development of central nervous system drugs. In an effort to understand its true potential, a framework for decision-making was proposed and the utility of pharmaco-electroencephalography was assessed through several case studies. A key finding was that lack of standardisation reduces the value of data pooling and meta-analyses and renders assessment of translatability difficult, limiting utility in all but simple cases. Pre-competitive collaboration is essential both to improving understanding of translation and developing modern signal processing techniques. Copyright © 2013 Elsevier Ltd. All rights reserved.

Riedel's thyroiditis (RT) is a rare chronic inflammatory disease of the thyroid gland. It is characterized by a fibroinflammatory process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation can mask an accompanying thyroid neoplasm and can mimic invasive thyroid carcinoma. Therefore, diagnosis can be difficult prior to surgical removal of the thyroid, and histopathologic examination of the thyroid is necessary for a definite diagnosis. The concurrent presence of RT and other thyroid diseases has been reported. However, to our knowledge, the association of RT with acute suppurative thyroiditis and micropapillary carcinoma has not been reported. We report a rare case of concurrent RT, acute suppurative thyroiditis, and micropapillary carcinoma in a 48-year-old patient.

Chemical burns of the oral mucosa: report of a case.

Clinical diagnosis of a chemical burn of the oral mucous membranes may be a diagnostic challenge. This article's intent is to illustrate the typical appearance of a chemical mucosal burn and to increase awareness of the various compounds which, when in contact with the mucous membranes, can result in a burn. The authors present a case involving a self-inflicted chemical injury of the oral mucous membranes and illustrate how the submission of an easily-obtained tissue specimen for pathologic examination may aid in the diagnosis. Because these superficial tissues can be obtained and submitted without the need for local anesthetic, pathologic examination is a quick, easy, and valuable diagnostic test when a patient's history is difficult to obtain or intentionally misleading.

2015-01-01

Osseous dysplasias are the most common subtype of fibro-osseous lesions of the maxillofacial bones. They are benign and often present as incidental asymptomatic lesions. Diagnosis can be made with clinical and radiographic examination. This article reports the case of a 47-year-old man with a huge cementifying osseous dysplasia of the maxilla that presented with secondary infection after teeth extraction and repair of oroantral fistula. A subtotal maxillectomy had to be done after conservative treatment failed to resolve the infection. Biopsy, tooth extraction or surgical trauma to the affected bones of osseous dysplasia could easily lead to severe secondary infection, the treatment of which may be very difficult, and thus should be avoided if possible.

Myalgia and elevated creatine kinase (CK) are occasionally observed during the treatment of hyperthyroid patients. Relative hypothyroidism resulted from rapid thyroid hormone reduction had been promoted as a plausible cause of these myopathic changes, however rarely reported. We hereby presented a 20-year-old female with Grave's disease, who developed myopathy and elevated CK during rapid correction of thyroid hormone. Relative hypothyroidism-induced myopathy. Antithyroid drug (ATD) dosage was reduced without levothyroxine replacement. The muscular symptoms were recovered with CK level returned to normal after adoption of the euthyroid status. Differentiation of relative hypothyroidism from other causes of myopathy, especially with the effect of ATD, is important for clinical practice, although difficult in many cases.

Phenytoin is one of the most well established and most effective antiepileptic medications for the treatment of focal seizures. In our clinical practice, it has proven difficult to maintain therapeutic phenytoin levels in infants less than three months of age. Incidence of phenytoin toxicity in infants is very rare. The cytochrome P450 super family plays an important role in phenytoin metabolism, especially CYP2C9 and CYP2C19. In this case report, we profiled a two-month-old Thai infant who developed phenytoin toxicity resulting from CYP2C9 gene polymorphism. Copyright © 2015 The Japanese Society of Child Neurology.

2006-12-01

The goal of this work is to report five cases of Melkersson-Rosenthal syndrom with a literature review. It is a rare entity and is characterized in its complete presentation, by the association of reccurent orofacial swelling, peripheral facial palsy and plicated tongue. Incomplete forms are more frequent and more difficult to establish its diagnosis. This latter is based on major and minor clinical and histological critieria sorted in three levels. There is four forms of MRS. The pathogenesis of this syndrome is still unknown; treatment remains random. It is based on topical or systemic steroids with or without cheiloplastic procedure. We must think of MRS in presence of any recurrent peripheral facial palsy and/or chronic facial swelling.

We report a rare case of left paraduodenal hernia in patient with symptoms of abdominal subobstruction treated successful with laparoscopic management in urgent situation that have reduced the length of stay and postoperative pain. Internal hernia is only 1% of the causes of abdominal obstruction and the left paraduodenal hernia about 50% of them; it is a congenital defect that derive from malrotation and abnormal mesenteric adhesion. The modern imaging techniques help for the correct diagnosis despite difficult identification of the pathology for the various clinical presentation. The treatment of choice is the surgical intervention; the laparoscopic approach is rarely described in literature but it can reduce the morbidity, postoperative pain and the length of hospital stay.

Eosinophilic gastroenteritis is an uncommon condition characterized by focal or diffuse infiltration of eosinophils in the gastrointestinal tract in the absence of secondary causes. The pathogenesis of this condition is not well understood and its clinical presentation depends on the segment and layer of the gastrointestinal tract affected. The definition of eosinophilic gastroenteritis may be difficult, as the normal ranges of eosinophil numbers in normal and abnormal gastric and intestinal mucosa are not standardized. We present the case of a 59-year-old male who came to the hospital with hypovolemic shock and lethargy secondary to severe diarrhea. Laboratory analysis was significant for peripheral eosinophilia, and pathology from both the duodenum and colon showed marked eosinophilic infiltration. PMID:26078733

[Penoscrotal elephantiasis].

Zugor, V; Horch, R E; Engehausen, D G; Schott, G E

2007-05-01

Penoscrotal elephantiasis is not an uncommon clinical picture that may arise as a symptom of many diseases; it is usually a sequela of a recurring inflammatory process, eczema or malignancy. Elephantiasis often occurs after radical operations in the pelvic region. Displacement of lymphatic pathways leads to a local edema which over the course of time may lead to a considerable increase in volume of the patient's genitals or other affected parts. The diagnosis of elephantiasis is not difficult. It is much more difficult to determine which disease has caused the obstruction of the lymphatic pathways. If it is a reversible stage, the object of treatment is to remove the obstruction and reinstate the physiological lymph flow. Conservative measures such as administration of anti-inflammatory drugs and diuretics, physical measures such as baths, massage, elevation of the affected parts and treatment of the underlying disease may be considered. On progression to irreversible elephantiasis a chronic lymphatic edema occurs for which conservative measures will be unsuccessful. For cases where physical and anti-inflammatory measures are unsuccessful, excision and amputation of the affected penoscrotal region is recommended in order to eliminate the functional dysfunction. We report on two cases of penoscrotal elephantiasis, one in a child and the other in an adult man.

The nurse's odyssey: the professional folktale in New Zealand backblocks nurses' stories, 1910-1915.

PubMed

Wood, Pamela J

2009-06-01

Nurses have a long tradition of storytelling. Nurses in the New Zealand government's Backblocks Nursing Service, established in 1909 for settlers in remote rural areas, related narratives of personal experience in articles, conference papers and letters to their chief nurse that were published in the country's nursing journal. Analysis of the 16 stories published between 1910 and 1915 revealed 14 had a common storyline and structure. Structural elements included a call, arduous journey, arrival and reconnaissance, trial (difficult case or circumstance), resolution and homily. Using a literary folkloristics approach, this article argues that repetition of the story by nurses in different regions traditionalised it as a professional folktale, 'The nurse's odyssey'. It enabled nurses to debrief from difficult cases and write-into-being this new role and practice. Striking differences in the practice setting ensured the story's reportability, while clinical details connected writer and readers through a common professional aesthetic context and strengthened the story's credibility. For the chief nurse who was also a journal editor, publishing the stories allowed her to potentially attract nurses to the service while alerting them to its harsh realities, and show policy-makers the profession's value in meeting new health service needs.

Recent advances in basic neuroscience research across a wide range of methodologies have contributed significantly to our understanding of human cortical electrophysiology and functional brain imaging. Translation of this research into clinical neurosurgery has opened doors for advanced mapping of functionality that previously was prohibitively difficult, if not impossible. Here we present the case of a unique individual with congenital blindness and medically refractory epilepsy who underwent neurosurgical treatment of her seizures. Pre-operative evaluation presented the challenge of accurately and robustly mapping the cerebral cortex for an individual with a high probability of significant cortical re-organization. Additionally, a blind individual has unique priorities in one’s ability to read Braille by touch and sense the environment primarily by sound than the non-vision impaired person. For these reasons we employed additional measures to map sensory, motor, speech, language, and auditory perception by employing a number of cortical electrophysiologic mapping and functional magnetic resonance imaging methods. Our data show promising results in the application of these adjunctive methods in the pre-operative mapping of otherwise difficult to localize, and highly variable, functional cortical areas.

There has been an increase in ethno-cultural, linguistic, and socio-demographical diversity in students enrolling in undergraduate nursing programs. Diversity also involves other characteristics, but little is known about how diversity impacts on the clinical experiences of nursing students. The aim of this review is to identify studies which describe the clinical placement experiences of nursing students who have a broad range of diversity characteristics. Major databases were searched and original studies published from 2003 to 30 June 2013 were eligible for inclusion. An expanded definition of diversity was used to include characteristics such as ethnicity, language, age, religion, gender, socioeconomic status, carer responsibilities, sexual orientation and special needs/disability. Male gender and speaking English as a second language are diversity characteristics associated with a less positive clinical experience. These students are also more likely to leave their nursing program. Mature-aged students and those from ethnic minority groups were also noted to have a less positive clinical experience and in some cases, this also increased attrition. However, it was difficult to determine the impact of these characteristics alone as they appeared to be linked with other characteristics such as financial difficulties and carer responsibilities in the case of mature-aged students, and language and international student status in the case of ethnicity. Given the significant benefits associated with preparing a diverse nursing workforce, it is an imperative to better understand the impact of diversity on nursing students to ensure that every placement becomes a positive and valuable learning experience.

Search engine as a diagnostic tool in difficult immunological and allergologic cases: is Google useful?

Web search engines are an important tool in communication and diffusion of knowledge. Among these, Google appears to be the most popular one: in August 2008, it accounted for 87% of all web searches in the UK, compared with Yahoo's 3.3%. Google's value as a diagnostic guide in general medicine was recently reported. The aim of this comparative cross-sectional study was to evaluate whether searching Google with disease-related terms was effective in the identification and diagnosis of complex immunological and allergic cases. Forty-five case reports were randomly selected by an independent observer from peer-reviewed medical journals. Clinical data were presented separately to three investigators, blinded to the final diagnoses. Investigator A was a Consultant with an expert knowledge in Internal Medicine and Allergy (IM&A) and basic computing skills. Investigator B was a Registrar in IM&A. Investigator C was a Research Nurse. Both Investigators B and C were familiar with computers and search engines. For every clinical case presented, each investigator independently carried out an Internet search using Google to provide a final diagnosis. Their results were then compared with the published diagnoses. Correct diagnoses were provided in 30/45 (66%) cases, 39/45 (86%) cases, and in 29/45 (64%) cases by investigator A, B, and C, respectively. All of the three investigators achieved the correct diagnosis in 19 cases (42%), and all of them failed in two cases. This Google-based search was useful to identify an appropriate diagnosis in complex immunological and allergic cases. Computing skills may help to get better results.

Image-based diagnostic aid for interstitial lung disease with secondary data integration

Interstitial lung diseases (ILDs) are a relatively heterogeneous group of around 150 illnesses with often very unspecific symptoms. The most complete imaging method for the characterisation of ILDs is the high-resolution computed tomography (HRCT) of the chest but a correct interpretation of these images is difficult even for specialists as many diseases are rare and thus little experience exists. Moreover, interpreting HRCT images requires knowledge of the context defined by clinical data of the studied case. A computerised diagnostic aid tool based on HRCT images with associated medical data to retrieve similar cases of ILDs from a dedicated database can bring quick and precious information for example for emergency radiologists. The experience from a pilot project highlighted the need for detailed database containing high-quality annotations in addition to clinical data. The state of the art is studied to identify requirements for image-based diagnostic aid for interstitial lung disease with secondary data integration. The data acquisition steps are detailed. The selection of the most relevant clinical parameters is done in collaboration with lung specialists from current literature, along with knowledge bases of computer-based diagnostic decision support systems. In order to perform high-quality annotations of the interstitial lung tissue in the HRCT images an annotation software and its own file format is implemented for DICOM images. A multimedia database is implemented to store ILD cases with clinical data and annotated image series. Cases from the University & University Hospitals of Geneva (HUG) are retrospectively and prospectively collected to populate the database. Currently, 59 cases with certified diagnosis and their clinical parameters are stored in the database as well as 254 image series of which 26 have their regions of interest annotated. The available data was used to test primary visual features for the classification of lung tissue patterns. These features show good discriminative properties for the separation of five classes of visual observations.

Review clinical experience with temporal fossa hemangiopericytomas (HPCs). Retrospective case series review. Tertiary referral center. Intracranial HPCs within the temporal fossa. Craniotomy for either subtotal or gross total tumor excision. Determination of clinical outcome (alive with no evidence of disease, alive with disease, and died of disease). Five cases of HPC involving the temporal fossa were treated at our tertiary referral center for the period from 1995 to 2008. All but 1 patient were men. The age of presentation ranged from 31 to 62 years, and duration of follow-up ranged from 8 to 153 months. Clinical presentation was protean; headache was the most common symptom. Gross total tumor excision was achieved in 2 patients, whereas subtotal tumor excision was achieved in 3 patients. Reasons for subtotal resection included excessive intraoperative blood loss and inextricable tumor. Histologically, all tumors were composed of tightly packed, randomly oriented (jumbled-up) tumor cells with little intervening collagen. CD34 staining mostly highlighted the vascular background. One patient died of disease, 2 patients were alive with disease, and 2 patients had no evidence of disease. Management of temporal fossa HPC is challenging because clinical presentation is often late, and extent of tumor excision is constrained by vital structures in the cranial base and intracranial contents. A multidisciplinary approach with neurosurgery and neurotology undertaken to achieve the most complete tumor resection possible, whereas minimizing morbidity are likely to confer a longer period of symptom-free survival and improves curability of these difficult lesions.

Atypical case of Wolfram syndrome revealed through targeted exome sequencing in a patient with suspected mitochondrial disease

PubMed Central

2012-01-01

Background Mitochondrial diseases comprise a diverse set of clinical disorders that affect multiple organ systems with varying severity and age of onset. Due to their clinical and genetic heterogeneity, these diseases are difficult to diagnose. We have developed a targeted exome sequencing approach to improve our ability to properly diagnose mitochondrial diseases and apply it here to an individual patient. Our method targets mitochondrial DNA (mtDNA) and the exons of 1,600 nuclear genes involved in mitochondrial biology or Mendelian disorders with multi-system phenotypes, thereby allowing for simultaneous evaluation of multiple disease loci. Case Presentation Targeted exome sequencing was performed on a patient initially suspected to have a mitochondrial disorder. The patient presented with diabetes mellitus, diffuse brain atrophy, autonomic neuropathy, optic nerve atrophy, and a severe amnestic syndrome. Further work-up revealed multiple heteroplasmic mtDNA deletions as well as profound thiamine deficiency without a clear nutritional cause. Targeted exome sequencing revealed a homozygous c.1672C > T (p.R558C) missense mutation in exon 8 of WFS1 that has previously been reported in a patient with Wolfram syndrome. Conclusion This case demonstrates how clinical application of next-generation sequencing technology can enhance the diagnosis of patients suspected to have rare genetic disorders. Furthermore, the finding of unexplained thiamine deficiency in a patient with Wolfram syndrome suggests a potential link between WFS1 biology and thiamine metabolism that has implications for the clinical management of Wolfram syndrome patients.

Without specific symptoms, diagnosis of febrile illness in returning travelers is challenging. Dengue, malaria, and enteric fever are common causes of fever in returning travelers and timely and appropriate treatment is important. However, differentiation is difficult without specific diagnostic tests. A retrospective study was conducted at the National Centre for Global Health and Medicine (NCGM) from April 2005 to March 2013. Febrile travelers returning from overseas who were diagnosed with dengue, malaria, or enteric fever were included in this study. Clinical characteristics and laboratory findings were compared for each diagnosis. During the study period, 86 malaria, 85 dengue, and 31 enteric fever cases were identified. The mean age of the study cohort was 33.1 ± 12 years and 134 (66.3%) study participants were male. Asia was the most common area visited by returning travelers with fevers (89% of dengue, 18.6% of malaria, and 100% of enteric fever cases), followed by Africa (1.2% of dengue and 70.9% of malaria cases). Clinical characteristics and laboratory findings were significantly different among each group with each diagnosis. Decision tree models revealed that returning from Africa and CRP levels < 10 mg/L were factors specific for diagnosis of malaria and dengue fever, respectively. Clinical manifestations, simple laboratory test results, and regions of travel are helpful to distinguish between dengue, malaria, and enteric fever in febrile returning travelers with non-specific symptoms.

Primary data collection is a critical activity in clinical research. Even with significant advances in technical capabilities, clear benefits of use, and even user preferences for using electronic systems for collecting primary data, paper-based data collection is still common in clinical research settings. However, with recent developments in both clinical research and tablet computer technology, the comparative advantages and disadvantages of data collection methods should be determined. To describe case studies using multiple methods of data collection, including next-generation tablets, and consider their various advantages and disadvantages. We reviewed 5 modern case studies using primary data collection, using methods ranging from paper to next-generation tablet computers. We performed semistructured telephone interviews with each project, which considered factors relevant to data collection. We address specific issues with workflow, implementation and security for these different methods, and identify differences in implementation that led to different technology considerations for each case study. There remain multiple methods for primary data collection, each with its own strengths and weaknesses. Two recent methods are electronic health record templates and next-generation tablet computers. Electronic health record templates can link data directly to medical records, but are notably difficult to use. Current tablet computers are substantially different from previous technologies with regard to user familiarity and software cost. The use of cloud-based storage for tablet computers, however, creates a specific challenge for clinical research that must be considered but can be overcome.

Generally, FDG-PET/CT image is acquired at the 60th minute after tracer administration. Depending on the clinical case, additional delayed scans may be useful. However, it is difficult to judge whether additional delayed scan is useful or not. The purposes of this study were creation and evaluation of educational programs to help radiological technologists to decide the usefulness of additional delayed scan of FDG-PET/CT. Educational programs consisted of the instructional materials and the judgment test of clinical cases. The instructional materials provided the valuable findings for differentiation between uptake in the wall of the colon and colon content, distinction between uptake in the lymph node and urinary tract, and evaluation of malignancy. The judgment test of clinical cases consisted of 10 cases selected by a nuclear medicine physician (for 5 of that cases additional delayed scan was decided to be useful). Five experienced technologists and five inexperienced technologists scored the volubility of additional delayed scan pre- and post-training using the instructional materials (the full marks of score is 5). After the educational programs using the instructional materials, the score was improved with the significant difference in both experienced (pre: 3.6±1.4, post: 4.0±1.2) and inexperienced (pre: 2.8±1.5, post: 3.7±1.5) groups (p<0.05). According to the educational programs, technologist might be able to decide whether the additional delayed scan is useful or not. The successful results of this study may improve the interpretation or reduce the total exposure dose of the PET/CT scan.

Clinical Ethics Support for Healthcare Personnel: An Integrative Literature Review.

2017-12-01

This study describes which clinical ethics approaches are available to support healthcare personnel in clinical practice in terms of their construction, functions and goals. Healthcare personnel frequently face ethically difficult situations in the course of their work and these issues cover a wide range of areas from prenatal care to end-of-life care. Although various forms of clinical ethics support have been developed, to our knowledge there is a lack of review studies describing which ethics support approaches are available, how they are constructed and their goals in supporting healthcare personnel in clinical practice. This study engages in an integrative literature review. We searched for peer-reviewed academic articles written in English between 2000 and 2016 using specific Mesh terms and manual keywords in CINAHL, MEDLINE and Psych INFO databases. In total, 54 articles worldwide described clinical ethics support approaches that include clinical ethics consultation, clinical ethics committees, moral case deliberation, ethics rounds, ethics discussion groups, and ethics reflection groups. Clinical ethics consultation and clinical ethics committees have various roles and functions in different countries. They can provide healthcare personnel with advice and recommendations regarding the best course of action. Moral case deliberation, ethics rounds, ethics discussion groups and ethics reflection groups support the idea that group reflection increases insight into ethical issues. Clinical ethics support in the form of a "bottom-up" perspective might give healthcare personnel opportunities to think and reflect more than a "top-down" perspective. A "bottom-up" approach leaves the healthcare personnel with the moral responsibility for their choice of action in clinical practice, while a "top-down" approach risks removing such moral responsibility.

A novel complete-case analysis to determine statistical significance between treatments in an intention-to-treat population of randomized clinical trials involving missing data.

PubMed

Liu, Wei; Ding, Jinhui

2018-04-01

The application of the principle of the intention-to-treat (ITT) to the analysis of clinical trials is challenged in the presence of missing outcome data. The consequences of stopping an assigned treatment in a withdrawn subject are unknown. It is difficult to make a single assumption about missing mechanisms for all clinical trials because there are complicated reactions in the human body to drugs due to the presence of complex biological networks, leading to data missing randomly or non-randomly. Currently there is no statistical method that can tell whether a difference between two treatments in the ITT population of a randomized clinical trial with missing data is significant at a pre-specified level. Making no assumptions about the missing mechanisms, we propose a generalized complete-case (GCC) analysis based on the data of completers. An evaluation of the impact of missing data on the ITT analysis reveals that a statistically significant GCC result implies a significant treatment effect in the ITT population at a pre-specified significance level unless, relative to the comparator, the test drug is poisonous to the non-completers as documented in their medical records. Applications of the GCC analysis are illustrated using literature data, and its properties and limits are discussed.

Fitz-Hugh-Curtis syndrome is a rare extra-pelvic complication of genital infection involving the perihepatic capsule. Most cases have been described in women in association with pelvic inflammatory disease; in rare cases it has been reported in men. Because the main symptom is acute abdominal pain, and laboratory and imaging findings are frequently nonspecific, the differential diagnosis, considering other gastrointestinal or renal diseases, can be difficult in the early stage of the syndrome, leading to frequent misdiagnosis and mismanagement. We report a case of Fitz-Hugh-Curtis syndrome in a 26-year-old man who first presented to the emergency department with acute abdominal pain, vomiting, and fever. Diagnosis was possible on the basis of clinical signs of orchiepididymitis, abnormal ultrasound findings, and specialist consultation with the Sexually Transmitted Infection Clinic. An acute gonoccocal infection was revealed, which was complicated by a collection of free perihepatic fluid and a subcapsular hypoechoic focal lesion. Prompt antibiotic therapy was established, with complete resolution of the symptoms within a few days. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Awareness of the clinical presentation, imaging, and laboratory findings during the acute phase of Fitz-Hugh-Curtis syndrome could help emergency physicians to make an early diagnosis and to correctly manage such patients. Improved diagnostic skills could prevent chronic complications that are especially a risk in the case of delayed or minor genitourinary symptoms. Copyright © 2015 Elsevier Inc. All rights reserved.

The World Health Organization's (WHO) case definition for childhood pneumonia, composed of simple clinical signs of cough, difficult breathing and fast breathing, is widely used in resource poor settings to guide management of acute respiratory infections. The definition is also commonly used as an entry criteria or endpoint in different intervention and disease burden studies. A group of paediatricians conducted a retrospective review of clinical and laboratory data including C-reactive protein concentration and chest radiograph findings among Filipino children hospitalised in the Bohol Regional Hospital who were enrolled in a pneumococcal vaccine efficacy study and had an episode of respiratory disease fulfilling the WHO case definition for clinical pneumonia. Our aim was to evaluate which disease entities the WHO definition actually captures and what is the probable aetiology of respiratory infections among these episodes diagnosed in this population. Among the 12,194 children enrolled to the vaccine study we recorded 1,195 disease episodes leading to hospitalisation which fulfilled the WHO criteria for pneumonia. In total, 34% of these episodes showed radiographic evidence of pneumonia and 11% were classified as definitive or probable bacterial pneumonia. Over 95% of episodes of WHO-defined severe pneumonia (with chest indrawing) had an acute lower respiratory infection as final diagnosis whereas 34% of those with non-severe clinical pneumonia had gastroenteritis or other non-respiratory infection as main cause of hospitalisation. The WHO definition for severe pneumonia shows high specificity for acute lower respiratory infection and provides a tool to compare the total burden of lower respiratory infections in different settings.

The purpose of this study was to evaluate predictors of reduction in ammonia levels by occlusion of portosystemic shunts (PSS) in patients with cirrhosis. Forty-eight patients with cirrhosis (21 women, 27 men; mean age, 67.8 years) with PSS underwent balloon-occluded retrograde transvenous obliteration (BRTO) at one institution between February 2008 and June 2014. The causes of cirrhosis were hepatitis B in one case, hepatitis C in 20 cases, alcohol in 15 cases, nonalcoholic steatohepatitis in eight cases, and other conditions in four cases. The Child-Pugh classes were A in 24 cases, B in 23 cases, and C in one case. The indication for BRTO was gastric varices in 40 cases and hepatic encephalopathy in eight cases. Testing was conducted before and 1 month after the procedure. Statistical analyses were performed to identify predictors of a clinically significant decline in ammonia levels after BRTO. Occlusion of PSS resulted in a clinically significant decrease in ammonia levels accompanied by increased portal venous flow and improved Child-Pugh score. Univariate analyses showed that a reduction in ammonia levels due to BRTO was significantly related to lower plasma glucose levels, higher RBC counts, and higher hemoglobin concentration before the treatment. Furthermore, multivariate logistic regression identified preoperative plasma glucose level as the strongest independent predictor of a significant ammonia reduction in response to BRTO. In addition, although BRTO resulted in significantly declined ammonia levels in patients with normal glucose tolerance before the procedure, ammonia levels were not significantly decreased after shunt occlusion in patients with diabetes mellitus or impaired glucose tolerance before BRTO, according to 75-g oral glucose tolerance test results. Preoperative plasma glucose level is a useful predictor of clinically significant ammonia reduction resulting from occlusion of PSS in patients with cirrhosis. Even if PSS are present, control of blood ammonia levels by BRTO alone may be difficult in patients with glucose intolerance.

Imaging Diagnosis of Splanchnic Venous Thrombosis

2015-01-01

Splanchnic vein thrombosis (SVT) is a broad term that includes Budd-Chiari syndrome and occlusion of veins that constitute the portal venous system. Due to the common risk factors involved in the pathogenesis of these clinically distinct disorders, concurrent involvement of two different regions is quite common. In acute and subacute SVT, the symptoms may overlap with a variety of other abdominal emergencies while in chronic SVT, the extent of portal hypertension and its attendant complications determine the clinical course. As a result, clinical diagnosis is often difficult and is frequently reliant on imaging. Tremendous improvements in vascular imaging in recent years have ensured that this once rare entity is being increasingly detected. Treatment of acute SVT requires immediate anticoagulation. Transcatheter thrombolysis or transjugular intrahepatic portosystemic shunt is used in the event of clinical deterioration. In cases with peritonitis, immediate laparotomy and bowel resection may be required for irreversible bowel ischemia. In chronic SVT, the underlying cause should be identified and treated. The imaging manifestations of the clinical syndromes resulting from SVT are comprehensively discussed here along with a brief review of the relevant clinical features and therapeutic approach.

Prostate cancer (PC) is one of the most important problems in modern oncology. According to statistical data, PC ranks second in the cancer morbidity structure in the Russian Federation and developed countries and its prevalence has been progressively increasing over the past decade. A need for early diagnosis and maximally accurate morphological verification of the diagnosis in difficult clinical cases (inconvenient tumor location for standard transrectal biopsy; gland scarring changes concurrent with prostatitis and hemorrhage; threshold values of prostate-specific antigen with unclear changes in its doubling per unit time; suspicion of biochemical recurrence or clinical tumor progression after special treatment) leads to revised diagnostic algorithms and clinically introduced new high-tech invasive diagnostic methods. This paper gives the first analysis of literature data on Russian practice using one of the new methods to verify prostate cancer (transrectal prostate cancer under magnetic resonance imaging (MRI) guidance).

Fat embolism syndrome (FES) is a known complication of traumatology, especially in long bone fractures. Fat embolic events are most often clinically insignificant and difficult to recognize since clinical manifestations are varied and there is no routine laboratory or radiographic diagnostic tool. Classically, FES presents with the triad of pulmonary distress, mental status changes, and petechial rash 24 to 48 hours after long-bone fracture. We report the intensive care management of a 16-year-old female patient who developed traumatic fat embolism syndrome. Traumatic fat embolism was diagnosed, based on suggestive clinical manifestations, radiographic and laboratory findings and confirmed by the demonstration of arterial hypoxemia in the absence of other disorders. Admission to the intensive care unit, mechanical ventilatory support with positive end-expiratory pressure and supportive therapy leaded to the patient's improvement and she was discharged with planned open reduction and internal fixation.

Personality disorders have a complex relationship with the law that in many ways reflects their complexity within the clinical and research communities. This paper addresses expert testimony about personality disorders, outlines how personality disorders are assessed in forensic cases, and describes how personality disorders are viewed in different legal contexts. Reasons are identified why personality disorders are not generally accepted as significant mental illness within the legal system, including high incidence of personality dysfunction in criminal populations, frequent comorbidity of personality disorders making it difficult to determine direct causation, and difficulty determining where on a continuum personality traits should be defined as illness (or not). In summary, the legal system, to a significant degree, mirrors the clinical conception of personality disorders as not severe mental diseases or defects, not likely to change, and most often, under volitional control.

The vast amount of clinical data in electronic health records constitutes a great potential for secondary use. However, most of this content consists of unstructured or semi-structured texts, which is difficult to process. Several challenges are still pending: medical language idiosyncrasies in different natural languages, and the large variety of medical terminology systems. In this paper we present SEMCARE, a European initiative designed to minimize these problems by providing a multi-lingual platform (English, German, and Dutch) that allows users to express complex queries and obtain relevant search results from clinical texts. SEMCARE is based on a selection of adapted biomedical terminologies, together with Apache UIMA and Apache Solr as open source state-of-the-art natural language pipeline and indexing technologies. SEMCARE has been deployed and is currently being tested at three medical institutions in the UK, Austria, and the Netherlands, showing promising results in a cardiology use case.

The maxillary molar distalization is a valuable therapeutic option in some clinical cases. Its biomechanics is challenging and difficult to obtain. Historically, various devices have been described offering successful solutions to this problem such as the Hilgers Pendulum Appliance (1992) and variants linked to mini screws which recently have shown interesting clinical potential. This article presents a new Pendulum variant using a miniscrew, the "pendulis". It follows the original concept (titanium-molybdenum alloy distalization springs and polymethyl-methacrylate pellet) but dental support is replaced by a single palatal miniscrew (median adults, para-median in children) to which the device is fixed by means of a metal welded cap easily positioned and removable by the practitioner. This allows for better control of the oral hygiene and completely controlled extraoral activation. Fabrication steps are described and instruction of use is illustrated with clinical documentation. © EDP Sciences, SFODF, 2014.

BACKGROUND: Primary fallopian tube carcinoma (PFTC) is a rare tumour of the female genital tract with an incidence of 0.1-1.8% of all genital malignancies, and it is very difficult to diagnose preoperatively, because of its non-specific symptomatology. In most cases, it is an intraoperative finding or a histopathological diagnosis. It is a tumour that histologically and clinically resembles epithelial ovarian cancer. CASE PRESENTATION: We are reporting a case of a 62-year-old, postmenopausal women with primary fallopian tube carcinoma of the right fallopian tube in stage IA. The patient has lower abdominal pain, watery vaginal discharge and repeated episodes of bleeding from the vagina. The clinical and radiological findings suggested a right adnexal tumour with elevated CA-125 levels. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy and peritoneal washing were performed. Pathologic confirmation of primary serous cystadenocarcinoma of the right fallopian tube was made. Peritoneal washings were negative for malignancy. FIGO stage was considered as IA, and the patient received no courses of chemotherapy and postoperative radiation because she refused it. Ten months after initial surgery, the patient is alive and in good condition. CONCLUSION: Cytoreduction surgery followed by adequate cycles of chemotherapy is an important strategy to improve patients’ prognosis. PMID:28698755

Pedunculated Pulmonary Artery Sarcoma Suggested by Transthoracic Echocardiography.

PubMed

2016-04-01

Pulmonary artery sarcoma (PAS) is an extremely rare malignancy. It is usually found after it grows large enough to occupy almost the entire lumen of the pulmonary artery and causes serious clinical symptoms. Thus, it is usually difficult to distinguish PAS from pulmonary thromboembolism based on imaging examinations. Few case reports had shown the attachment of PAS to pulmonary artery, a key characteristic for diagnosis, and differential diagnosis of PAS. In this case, we found a PAS, which did not cause local obstruction and some tumor emboli, which obstructed the branches of the pulmonary arteries and caused pulmonary hypertension and clinical symptoms. Transthoracic echocardiography (TTE) revealed a part of the tumor attached to the intima of the main pulmonary artery with a peduncle and had obvious mobility, which was suggestive of PAS and differentiated it from the pulmonary thromboembolism. To our knowledge, this is the first case report of a pedunculated PAS suggested by TTE. Combined with pulmonary artery computed tomography angiography, the diagnosis of PAS is strongly suggested before the operation. This case indicates that TTE could reveal the attachment and mobility of PAS in the main pulmonary and may provide useful information for the diagnosis and differential diagnosis of PAS, especially a pedunculated PAS. © 2015, Wiley Periodicals, Inc.

Surgical management of brain-stem cavernous malformations: report of 137 cases.

2003-06-01

With the improvement in neuroimaging and microsurgical techniques, brain stem cavernous malformations are no longer considered inoperable. Surgical indications for brainstem cavernoma are evolving, with better understanding of its natural history and decreasing surgical complications. During 1986 through 1998, a series of 137 patients (4 patients each with two brain stem lesions, total number of lesions, 141) with brain stem cavernous malformations were treated microsurgically at Beijing Neurosurgery Institute. The age distribution, lesion location, and clinical presentations were analyzed. The bleeding rate, surgical indications and microsurgical techniques were also discussed. In our series, 92 of 137 cases (67.2%) suffered more than one hemorrhage. Female patients had a higher risk of recurrent hemorrhage than that of male patients. Unlike cavernomas malformations from other locations, repeated hemorrhages from brain stem malformations are much more common and usually lead to new neurologic deficits. Among all 137 surgically treated patients, there was no operative mortality. Ninety-nine patients (72.3%) either improved or remained clinically stable postoperatively. The size of the cavernoma/hematoma does not necessarily correlate with the surgical result. While the acute hematoma can facilitate the surgical dissection, longer clinical history with multiple hemorrhages often makes total surgical resection difficult, partially because of the firmer capsule that may not shrink or collapse after hematoma is released. Pathologically those capsules were associated with more hyaline degeneration, fibrous proliferation and even calcifications. During the follow-up period between 0.5 to 11 years in 129 cases, 115 patients (89.2%) have been working, studying, or doing house work. Three patients (2.3%) suffered recurrent hemorrhages. Surgical indications of brain stem cavernoma include (1) progressive neurologic deficits; (2) overt acute or subacute hemorrhage on MRI either inside or outside cavernous malformations with mass effect; (3) cavernoma/hematoma reaching brainstem surface (<2 mm brain tissue between cavernoma /hematoma and pial surface). Grave clinical presentations like coma, respiratory, or cardiac instability are not surgical contraindications. Emergent surgical evacuation may lead to satisfactory outcome. Repeated hemorrhages will worsen the pre-existing neurologic deficits and possibly make the surgical dissections more difficult. Patients with minimum, stable neurologic deficits and lesion/hematoma that has not reached the brain stem surface should be followed conservatively.

Autoimmune hepatitis, one disease with many faces: Etiopathogenetic, clinico-laboratory and histological characteristics

Autoimmune hepatitis (AIH) is an unresolving progressive liver disease of unknown etiology characterized by hypergammaglobulinemia, autoantibodies detection and interface hepatitis. Due to the absence of specific diagnostic markers and the large heterogeneity of its clinical, laboratory and histological features, AIH diagnosis may be potentially difficult. Therefore, in this in-depth review we summarize the substantial progress on etiopathogenesis, clinical, serological and histological phenotypes of AIH. AIH has a global distribution affecting any age, both sexes and all ethnic groups. Clinical manifestations vary from asymptomatic to severe or rarely fulminant hepatitis. Hypergammaglobulinemia with selective elevation of IgG is found in most cases. Autoimmune attack is perpetuated, possibly via molecular mimicry, and favored by the impaired control of T-regulatory cells. Histology (interface hepatitis, emperipolesis and hepatic rosette formation) and autoantibodies detection although not pathognomonic, are still the hallmark for a timely diagnosis. AIH remains a major diagnostic challenge. AIH should be considered in every case in the absence of viral, metabolic, genetic and toxic etiology of chronic or acute hepatitis. Laboratory personnel, hepato-pathologists and clinicians need to become more familiar with disease expressions and the interpretation of liver histology and autoimmune serology to derive maximum benefit for the patient.

Leptospira spp. are delicate bacteria that cannot be studied by usual microbiological methods. They cause leptospirosis, a zoonotic disease transmitted to humans through infected urine of wild or domestic animals. We studied the incidence of this disease in the Uruguayan population, its epidemiologic and clinical features, and compared diagnostic techniques. After examining 6,778 suspect cases, we estimated that about 15 infections/100,000 inhabitants occurred yearly, affecting mainly young male rural workers. Awareness about leptospirosis has grown among health professionals, and its lethality has consequently decreased. Bovine infections were probably the principal source of human disease. Rainfall volumes and floods were major factors of varying incidence. Most patients had fever, asthenia, myalgias or cephalalgia, with at least one additional abnormal clinical feature. 30-40% of confirmed cases presented abdominal signs and symptoms, conjunctival suffusion and altered renal or urinary function. Jaundice was more frequent in patients aged > 40 years. Clinical infections followed an acute pattern and their usual outcome was complete recovery. Laboratory diagnosis was based on indirect micro-agglutination standard technique (MAT). Second serum samples were difficult to obtain, often impairing completion of diagnosis. Immunofluorescence was useful as a screening test and for early detection of probable infections.

Forensic medicine specialist in cooperation with clinical medicine consultants, on the basis of evidence analysis, which was gathered during procedures and contained in the acts has to create an objective and essential opinion. This opinion is a vital, very important and irreplaceable proof in every case. Judicial body consults with forensic medicine specialist or specialists if there are circumstances for settlement of which there is a need of classified informations - art. 193 of Penalty Code. Forensic medicine specialists face many difficulties which may have effect on quality, positiveness of opinion, compliance with the deadline, increasing expectancy of judicial body or sides. It is very difficult to find clinical specialists which except their clinical knowledge have basic knowledge about law, the role and duties of an court expert. In this article we discuss creating-opinion problems, role and position of court expert in confrontation with expectations of judicial body and the Justice with particular emphasis on medical mistakes and assessment of medical proceedings. We show the complexity of creating of medical opinions, especially these institutional.

Use of synthetic cannabinoids in patients with psychotic disorders: case series.

2014-01-01

An increasing number of synthetic cannabinoids have become available on the black market in recent years, and health professionals have seen a corresponding increase in use of these compounds among patients with psychiatric disorders. Unfortunately, there is almost no research available in the literature on this topic, and what little exists is based on case reports of individuals without psychiatric disorders. Synthetic cannabinoids are functionally similar to, but structurally different from, delta-9-tetrahydrocannabinol, the active principle in cannabis, and are problematic for many reasons. The psychotropic action of synthetic cannabinoids in patients with schizophrenia is unpredictable, with very diverse clinical presentations. These drugs can be much more potent than delta-9-tetrahydrocannabinol, they are readily available and difficult to detect. The gold standard for identification of synthetic cannabinoids is gas chromatography with mass spectrometry, but even this is difficult because new formulations of these designer drugs are constantly emerging. In this manuscript, we provide an overview and discussion of synthetic cannabinoids and present four cases of patients with synthetic cannabinoid intoxication who were hospitalized in our intensive psychiatric unit at the time of intoxication. All patients had a history of schizophrenia and had been hospitalized several times previously. While hospitalized, they smoked an unknown substance brought in by a visitor, which was then confirmed using gas chromatography with mass spectrometry to be the synthetic cannabinoid AM-2201. Our patients experienced predominantly psychiatric adverse clinical effects. We observed the appearance of new psychotic phenomena, without exacerbation of their previously known psychotic symptoms, as well as the occurrence or marked worsening of mood and anxiety symptoms. Despite several similar reactions, and even though they ingested the same exact substance, the clinical picture differed markedly between individual patients. We assume that the acute effects of synthetic cannabinoids in patients with schizophrenia would be different from those in persons without psychotic disorders. The reasons for this difference could be the actual symptomatology of the presenting disorder, the impact of psychopharmacotherapy, individual patient differences and probably many, as yet unknown, factors. The long-term consequences of synthetic cannabinoid use on preexisting psychotic disorders are unclear.

The authors report the case of a 53-year-old man, with a long-standing history of mild mitral stenosis, admitted for worsening fatigue. Transthoracic echocardiography (limited by poor image quality) showed mitral annular calcification, leaflets that were difficult to visualize and an estimated mitral valve area of 1.8 cm(2) by the pressure half-time method. However, elevated mean transmitral and right ventricle/right atrium gradients were identified (39 and 117 mmHg, respectively). This puzzling discrepancy in the echocardiographic findings prompted investigation by transesophageal echocardiography, which revealed an echogenic structure adjacent to the mitral annulus, causing severe obstruction (effective orifice area 0.7 cm(2)). The suspicion of supravalvular mitral ring was confirmed during surgery. Following ring resection and mitral valve replacement there was significant improvement in the patient's clinical condition and normalization of the left atrium/left ventricle gradient. Supravalvular mitral ring is an unusual cause of congenital mitral stenosis, characterized by an abnormal ridge of connective tissue on the atrial side of the mitral valve, which often obstructs mitral valve inflow. Few cases have been reported, most of them in children with concomitant congenital abnormalities. Diagnosis of a supravalvular mitral ring is challenging, since it is very difficult to visualize in most diagnostic tests. It was the combination of clinical and various echocardiographic findings that led us to suspect this very rare condition, enabling appropriate treatment, with excellent long-term results.

At Intermountain Healthcare (Intermountain), executive clinical content experts are responsible for disseminating consistent evidence-based clinical content throughout the enterprise at the point-of-care. With a paper-based system it was difficult to ensure that current information was received and was being used in practice. With electronic information systems multiple applications were supplying similar, but different, vendor-licensed and locally-developed content. These issues influenced the consistency of clinical practice within the enterprise, jeopardized patient and clinician safety, and exposed the enterprise and its employees to potential financial penalties. In response to these issues Intermountain is developing a knowledge management infrastructure providing tools and services to support clinical content development, deployment, maintenance, and communication. The Intermountain knowledge management philosophy includes strategies guiding clinicians and consumers of health information to relevant best practice information with the intention of changing behaviors. This paper presents three case studies describing different information management problems identified within Intermountain, methods used to solve the problems, implementation challenges, and the current status of each project.

Histoid leprosy: review of the literature.

Leprosy is a chronic granulomatous inflammation primarily of the peripheral nervous system, skin, and reticuloendothelial system caused by Mycobacterium leprae. It presents clinically as an erythematous or hypopigmented anesthetic patch and a thickened and/or tender cutaneous nerve trunk. Leprosy is also called Hansen disease. Leprosy is a great imitator of other skin diseases, and it can present with different morphological lesions, which is why an expert eye is needed to diagnose it. One of the important clinical presentations of leprosy is histoid leprosy, which is very difficult to diagnose due to different clinical and histopathological findings that mimic, e.g., a fibromatous disorder. Histoid leprosy is a very rare clinicopathological variant of leprosy. It is clinically characterized by skin-colored, soft, succulent nodules, and plaques on apparently normal skin and histologically by a dense bundle of histiocytes arranged in storiform. Though histoid leprosy is a very rare type of leprosy, the higher load of lepra bacilli in these cases makes it a concern as a reservoir for leprosy. © 2015 The International Society of Dermatology.

Anomalies of the first branchial cleft (FBC) are uncommon, and recognizing them can be difficult. Although present at birth, many cases do not become evident until later in childhood or adolescence, with an initial clinical presentation in adulthood being encountered only rarely. Typically, FBC anomalies present as a unilateral cyst, sinus, or fistula associated with the external auditory canal, or with swelling or an inflammatory opening in the peri-auricular/parotid area. They are commonly misdiagnosed and are often treated inadequately before being excised completely. A 40-year-old woman presented to the maxillofacial outpatient clinic with an episode of bilateral pre-auricular tumefaction, initially diagnosed as temporomandibular dysfunction syndrome. This was associated with bilateral pre-auricular pain that increased with mandibular movements. In relation to the patient's history, and given the bilateral presence of a pre-auricular pit, a diagnosis of FBC anomaly was made. Further investigation showed a related asymptomatic history in five other cases across four generations of the same family. The authors describe here the case, the diagnostic methodology, and the wide local excision technique used for removal of the branchial sinus.

Congenital nephrogenic diabetes insipidus is a rare, hereditary in nature, characterized by an inability of the kidney to concentrate urine, secondary to the manifold resistance to the action of vasopressin. X-linked forms of transmission (90%) are expressed in boys, from the neonatal period in general, by polyuria and polydipsia. Symptomatology in transmissive girls is variable but can sometimes be quite marked. These forms are secondary to mutations in the gene encoding the vasopressin V2 receptor, located at position Xq28, responsible for a loss of function of this receptor. Some of these mutations may cause a partial phenotype, less severe. Forms of autosomal, recessive or dominant are more rare (10%). Treatment is symptomatic, sometimes difficult in infants. It aims to avoid episodes of dehydration. It is based on a conventional diet hypo-osmotic and administration of hydrochlorothiazide and indomethacin. We report here the case of a child with congenital nephrogenic diabetes insipidus hospitalized at Children's Hospital of Rabat and throughout this case we review the pathophysiology and clinical and biological characteristics of the disease and including importance of contribution of clinical biochemistry laboratory in the diagnosis and monitoring of this disease.

Every doctor can be confronted, during his career, with patients presenting symptoms they created themselves. Because it is easily accessible, the hand is a favored target organ for these self-inflicted injuries. The diagnosis of factitious disorder of the hand is very difficult, rarely suggested and widely under-estimated. The real issue is detecting it early on to develop a cohesive diagnostic and therapeutic approach. The three clinical cases reported in this article illustrate the difficulty of caring for this pathology at all stages, from diagnosis to treatment. These disorders must be distinguished from malingering. A psychiatrist must be part of the treatment team. The prognosis of factitious disorders is poor. It is vital to maintain contact with the patient once the diagnosis is established. The risk is that the patient consults with other professionals, restarting a new cycle. The featured clinical cases were chosen to remind surgeons that factitious disorders of the hand are a recognized psychiatric disease. It must be evoked in the context of an unusual injury with a vague history. Everything possible must be done to confirm the diagnosis and avoid surgery. Copyright © 2018 SFCM.

Hysteroscopy has widely been used for diagnosis of the uterine cavity; however, target biopsy has often been difficult in part to the inherent limitations of ancillary instruments. Lin's biopsy grasper was specifically designed to work in conjunction with a flexible hysteroscope to obtain intrauterine biopsy under transabdominal sonography. Herein, we share our clinical experience in the management of endometrial abnormalities with the use of Lin's biopsy grasper during office-based hysteroscopy. From February 2006 to November 2016, the use of Lin's biopsy grasper for tissue biopsy was attempted on 126 cases. We retrospectively recorded and analyzed the patients' preoperative characteristics and biopsy outcomes to demonstrate the feasibility and efficacy of Lin's biopsy grasper. Out of the one hundred and twenty-six enrolled patients, satisfactory targeted biopsies were achieved; including high diagnostic rate (92.1%, with 116 cases confirmed histologically) and adequate tissue retrieval (77.8%, with 98 cases obtaining optimal specimen volume). All patients tolerated the procedure without analgesics or anesthesia. Diagnostic flexible hysteroscopy combined with the use of Lin's biopsy grasper has proven to be an effective tool for intrauterine evaluation and obtaining tissue sample. Copyright © 2018.

We present a rare case of malignant epithelial neoplasm of the appendix, an uncommon disorder encountered in clinical practice, which poses a variety of diagnostic and therapeutic challenges. We report a particular case in which the appendix was abnormally located in the pelvis, mimicking an adnexal mass. Therefore, it was difficult to make the preoperative diagnosis on clinical examination, imaging studies and laboratory tests and we discovered the lesion during the diagnostic laparoscopy. No lymphadenopathy or mucinous ascites were found. The case was completely handled via the laparoscopic approach keeping the appendix intact during the operation. The frozen section, the detailed histopathology overview as well as multiple immunostaining with a complex panel of markers report diagnosed a low-grade appendiceal mucinous neoplasm (LAMN) with no invasion of the wall. No adjuvant therapy was considered needed. At a one-year follow-up oncological assessment, the patient was free of disease. In women with cystic mass in the right iliac fossa an appendiceal mucocele should be considered in the differential diagnosis. Laparoscopic appendectomy can represent an adequate operation for the appendiceal mucinous neoplasm if the histological report is clear and surgical precautionary measures are taken.

A population-based cohort of people with a clinical diagnosis of Prader-Willi syndrome (PWS) was genetically assessed using molecular diagnostic methods and subsequently divided into the following genetic subtypes involving chromosome 15: 'deletion', 'disomy' and genetically negative (referred to as 'PWS-like'). The physical and behavioral characteristics of the three groups were compared in order to evaluate the unique characteristics of the phenotype resulting from loss of expression of imprinted genes at 15q11q13 (PWS vs. PWS-like cases), the possible effect of either haploid insufficiency of non-imprinted genes (deletion cases), or gain of function of imprinted genes (disomy cases) located within the PWS critical region at 15q11q13. In this study, the main differences between probands with either a deletion or disomy are considered, and the possible involvement of contributing genes discussed. The differences within the PWS group proved difficult to quantify. It would appear that haploid insufficiency or gain of function are more subtle contributors than gender-specific genomic imprinting in the production of the PWS phenotype.

Our purpose was to report a case of adult pancreatoblastoma, and review the literature in order to assist clinicians in the management of the disease. The demographic, clinical, and imaging findings of 41 patients with pathologically proven pancreatoblastoma from 1986 to 2017 identified in PubMed were reviewed. The key words used for searching PubMed were: "pancreatoblastoma", "pancreatic tumor", and "adult pancreatoblastoma." We also reported the details of a case of adult pancreatoblastoma treated at our institution. We identified 41 cases of adult pancreatoblastomas, and the mean age at diagnosis was 41.4 ± 17.4 years. Pancreatoblastomas occurred in the pancreatic head in 48.4% of patients, and in 39.0% of cases the tumor was >8 cm in diameter at diagnosis. Patient age and tumor size were similar between males and females (P = 0.59; P = 0.32, respectively). Metastases was present in 17 of the 41 adult patients (41.5%). No significant difference in age, sex, tumor size, and tumor location was found between patients with and without metastases (P = 0.57, 0.58, 0.64, 0.39, respectively). Preoperative diagnosis of adult pancreatoblastoma is difficult because of the heterogeneous, variable cellular differentiation and atypical clinical and imaging features. A pancreatoblastoma should be considered when tumors in the pancreas are solid and cystic. Copyright © 2018. Published by Elsevier Inc.

Primary omental gangrene mimicking appendicular perforation peritonitis-A case report.

PubMed

Kumar, A; Shah, J; Vaidya, P

2016-01-01

Primary omental torsion is a rare cause of acute abdomen in adults and presents with variable signs and symptoms. Establishing a preoperative diagnosis may be difficult in the emergency setting. It is rarely diagnosed preoperatively as it mimics common surgical emergencies such as acute appendicitis, appendicular perforation, acute cholecystitis and perforated peptic ulcers and can lead to the clinical deterioration of patient if missed A 47 years old male was taken to the operating room with a diagnosis of appendicular perforation peritonitis and during surgery was found to have a primary omental gangrene with pyoperitoneum, for which omentectomy and peritoneal lavage was performed. Torsion of the omentum is a condition in which the organ twists on its long axis to such an extent that its vascularity is compromised. Omental torsion can be primary (idiopathic) or secondary, depending on an underlying cause. Primary omental torsion was first described by Eitel in 1899. However, very few cases have been reported. Our case was a rare case presenting with omental gangrene with pyoperitoneum mimicking appendicular perforation peritonitis. Primary omental torsion is a rare diagnosis. A high index of clinical suspicion is required for a preoperative diagnosis. In doubtful cases a CT scan may be helpful. Surgical excision of the omentum remains the treatment of choice; however, conservative management may be attempted in an uncomplicated omental torsion. Copyright © 2016 The Authors.

Munchausen syndrome in the emergency department mostly difficult, sometimes easy to diagnose: a case report and review of the literature

PubMed Central

2009-01-01

Munchausen syndrome is a rare psychiatric disorder in which patients inflict on themselves an illness or injury for the primary purpose of assuming the sick role. Because these patients can present with many different complaints and clinical symptoms, diagnosis is often made at a later stage of hospitalisation. In contrast we report a case of a 40-year old woman very easy to diagnose with Munchausen syndrome. This trained nurse presented at our emergency department (ED) complaining of abdominal pain. Interviewed by the medical trainee, she immediately confessed having put a knitting needle into her urethra four days earlier. She was not able to remove it anymore because it was beyond her reach. Abdominal X-ray confirmed the presence of the needle and a median laparotomy was performed to remove it. The diagnosis of Munchausen syndrome seemed immediately obvious in this case. PMID:19909508

Pseudoaneurysm of the Profunda Femoris Artery following Blunt Trauma Treated by Endovascular Coil Embolization: Review of Two Cases and Relevant Literature

PubMed Central

McNerney, Patrick; Kiproff, Paul

2017-01-01

Profunda femoris artery (PFA) pseudoaneurysm after blunt trauma without associated femur fracture is a rare occurrence. Most of the reported cases of PFA pseudoaneurysm in the English literature developed after penetrating trauma, surgical procedures, and femur fractures. We present two such cases following blunt trauma and without any associated long bone injury. After initial imaging failed to show any long bone fracture, CT angiography confirmed pseudoaneurysm of the branch of the PFA. Both patients were then treated with emergent coil embolization of the bleeding vessel. Pseudoaneurysms typically present late and signs of persistent hip pain, thigh swelling, presence of a pulsatile mass, and even unexplained anemia all may suggest the diagnosis. Recognition of PFA pseudoaneurysm requires high index of suspicion and is often difficult to diagnose clinically because of its location. PMID:28246563

Small cell sweat gland carcinoma of childhood

2005-01-01

Small cell sweat gland carcinoma appears to represent a very unusual histological type of sweat gland anlage tumour presenting in children. The differential diagnosis from other small blue cell tumours involving the skin is often difficult. The present report confirms the original observation describing two patients of 2 and 5 years of age harbouring cutaneous tumours. The histology of these lesions showed a monomorphic proliferation of small cells with a high mitotic rate and areas of necrosis. Immunohistochemically, the cells were negative for desmin, cytokeratin 7, cytokeratin 20, Cam 5.2, CD99, chromogranin, CD56, synaptophysin, and S-100, and focally positive for the pancytokeratin marker AE1/AE3, carcinoembryonic antigen (one case), and neurone specific enolase (one case). The prognosis of this type of tumour seems to be good. As more cases are added, the clinical pathological spectrum of the lesion will become better defined. PMID:16311358

Angiolymphoid hyperplasia with eosinophilia: a clinicopathologic study of 9 cases.

2014-03-01

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare disease characterized by single or multiple angiomatous lesions typically located on the scalp and the face. We present a retrospective analysis of 9 cases of ALHE. The lesions appeared largely as multiple grouped papules or, in some cases, subcutaneous nodules, located mainly on the scalp, particularly around the ear. We also observed lesions in atypical locations, such as areas of the head other than the scalp, and the shoulder, neck, and forearm. At these sites the lesions had an atypical clinical appearance that made diagnosis difficult; this should be borne in mind in patients with single, well-delimited lesions with a vascular appearance and superficial ulceration or crusting. Surgery was the most common treatment in our series, and even though ALHE is considered a benign condition, recurrence was common. Copyright © 2012 Elsevier España, S.L. and AEDV.

2014-01-01

Background. Chronic graft versus host disease (cGVHD) is a complication following bone marrow transplantation. The oral lesions are difficult to control with a systemic pharmacological therapy. Case Description. A 63-year-old female patient, who underwent an allogeniec transplantation for acute myeloid leukemia, developed a chronic oral and cutaneous GVHD. The patient was treated with topical tacrolimus 0.1%, twice daily for two months, and underwent a protocol of oral hygiene characterized by 3 appointments of scaling, root planning, and daily oral hygiene instructions. The patient showed marked resolution of gingival lesions and a significant improvement of related pain and gingival inflammatory indexes. Clinical Implications. This case report suggests that treatment with topical tacrolimus and professional oral hygiene may be helpful in the management of chronic oral GVHD with severe gingival involvement. PMID:24639902

Primary synovial sarcoma (SS) of the kidney is a rare neoplasm and its presenting features are similar to other common renal tumors, making early diagnosis difficult. To date, few cases have been reported in the literature. Primary renal SSs can exist in either a monophasic or a biphasic pattern, the former being more common and tending to have a better prognosis than the biphasic variant. Herein we describe a case of primary renal SS that was diagnosed based on histopathology and immunohistochemistry after radical nephrectomy. Fusion gene product analysis was also done by FISH and RT-PCR. Patient follow-up and literature review are presented, focused on systemic therapy. We highlight that these tumors should be correctly diagnosed as clinical results and specific treatment are distinct from primary epithelial renal cell carcinoma. Adjuvant chemotherapy should be tailored for each patient in the management of disease, although its role still remains unclear. PMID:24137053

[Ulcerating Herpes simplex infections in intensive care patients].

Fischer, M; Wohlrab, J; Radke, J; Marsch, W C; Soukup, J

2002-11-01

Herpes simplex infections are potentially a life-threatening situation for immunocompromised as well as critically ill patients. The correct diagnosis is made more difficult in comatose patients by the fact that the characteristic symptom of extreme pain cannot be registered. The clinical dermatological findings (polycyclic configuration, easily bleeding ulcers) are thus especially important in patients under intensive care conditions. As examples, the cases of 3 critically ill patients (subarachnoid bleeding or head injury) developing therapy-resistant, flat sacral or perioral skin ulcers with peripheral blisters are presented. Herpes simplex virus was confirmed immunohistologically and in the smear test. All patients subsequently died. These cases emphasize that patients in the intensive care unit are in danger of developing a chronic persistent Herpes simplex infection due to latent immunosuppression. Chronic persistent Herpes infections may be underrated in intensive therapy, and must always be ruled out in case of therapy-resistant erosions or ulcerations.

2014-06-01

Puerperal uterine inversion is a rare and potentially life-threatening complication of a mismanaged third stage of labour. Early diagnosis is mandatory for proper management of the patient. Complete uterine inversion is a clinical diagnosis. However, incomplete uterine inversion is difficult to identify and warrants further workup. Sonographic evaluation, although a bedside procedure, may be confusing. The conspicuity of findings is much greater on MR examination than on ultrasound. Only a few diagnostic imaging findings in uterine inversion have been described in previous reports. We present the case of a 26-year-old woman who had a full-term vaginal delivery and presented after 20 days with acute urinary retention and mild vaginal bleeding. She was diagnosed as a case of neglected subacute incomplete uterine inversion. Both greyscale and Doppler sonographic and MR features of the case are described with an emphasis on better delineation of uterine and adnexal anatomy on MR imaging.

Solitary Rectal Ulcer Syndrome: A Paediatric Case Report

Abreu, Marlene; Azevedo Alves, Raquel; Pinto, João; Campos, Miguel; Aroso, Sofia

2017-01-01

Introduction Solitary rectal ulcer syndrome (SRUS) is an uncommon benign rectal disease. Mostly young adults are affected, and it is rare in paediatric populations. Clinical Case We present a 12-year-old girl with a 6-month history of tenesmus, frequent defaecation, and bloody stools with mucus. There was no previous history of constipation or other symptoms. At the first visit, physical examination and routine laboratory test results were normal. A stool examination for bacteria and parasites was negative. Colonoscopy revealed a single ulcer in the distal rectum 6 cm from the anal margin. SRUS was confirmed by biopsy. Despite conservative measures, the symptoms persisted. A defaecation proctography showed a small rectocele with no rectal mucosal prolapse. Because of its proximity to the anal sphincter, no surgical intervention was performed. Conclusion The present case illustrates how difficult the management of SRUS is. Multicentre studies are needed to establish treatment protocols for children. PMID:28848799

Validity threats: overcoming interference with proposed interpretations of assessment data.

PubMed

Downing, Steven M; Haladyna, Thomas M

2004-03-01

Factors that interfere with the ability to interpret assessment scores or ratings in the proposed manner threaten validity. To be interpreted in a meaningful manner, all assessments in medical education require sound, scientific evidence of validity. The purpose of this essay is to discuss 2 major threats to validity: construct under-representation (CU) and construct-irrelevant variance (CIV). Examples of each type of threat for written, performance and clinical performance examinations are provided. The CU threat to validity refers to undersampling the content domain. Using too few items, cases or clinical performance observations to adequately generalise to the domain represents CU. Variables that systematically (rather than randomly) interfere with the ability to meaningfully interpret scores or ratings represent CIV. Issues such as flawed test items written at inappropriate reading levels or statistically biased questions represent CIV in written tests. For performance examinations, such as standardised patient examinations, flawed cases or cases that are too difficult for student ability contribute CIV to the assessment. For clinical performance data, systematic rater error, such as halo or central tendency error, represents CIV. The term face validity is rejected as representative of any type of legitimate validity evidence, although the fact that the appearance of the assessment may be an important characteristic other than validity is acknowledged. There are multiple threats to validity in all types of assessment in medical education. Methods to eliminate or control validity threats are suggested.

Background Tuberculous meningitis (TBM) is one of the common clinical manifestations of extra-pulmonary tuberculosis. It is difficult to diagnose due to a lack of rapid, sensitive, and specific tests. Newer methods, which are easy and reliable, are required to diagnose TBM at an early stage. Thus our aim was to evaluate the polymerase chain reaction (PCR) technique, using primers directed against the IS6110 gene, for the detection of Mycobacterium tuberculosis in the CSF, for the diagnosis of TBM patients. Methods An in-house IS6110 PCR method using a specific pair of primers designed to amplify the insertion sequence, IS6110, in the M. tuberculosis genome was used to analyze CSF. A total of 80 CSF samples from different groups of patients were studied (confirmed TBM n = 35, clinically suspected TBM n = 16, non-TBM infectious meningitis n = 12, non infectious neurological diseases n = 17). Results PCR gave a sensitivity of 91.4% and specificity of 75.9% for the diagnosis of TBM in patients with TBM confirmed by culture. In 16 clinically diagnosed, but unconfirmed, TBM cases PCR was positive in 10 (62.5%) cases. There were seven (24.1%) PCR-positive cases among the 29 patients with non-TBM and non-infectious neurological disease. Conclusion We conclude that the performance of an in-house IS6110 PCR assay is valuable in the rapid diagnosis of tuberculous meningitis. PMID:17976247

The clinical heterogeneity of prostate cancer (PCa) makes it difficult to identify those patients that could benefit from more aggressive treatments. As a contribution to a better understanding of the genomic changes in the primary tumor that are associated with the development of high-risk disease, we performed exome sequencing and copy number determination of a clinically homogeneous cohort of 47 high-risk PCas. We confirmed recurrent mutations in SPOP, PTEN and TP53 among the 850 point mutations we detected. In seven cases, we discovered genomic aberrations in the TET1 (Ten-Eleven Translocation 1) gene which encodes a DNA hydroxymethylase than can modify methylated cytosines in genomic DNA and thus is linked with gene expression changes. TET1 protein levels were reduced in tumor versus non-tumor prostate tissue in 39 of 40 cases. The clinical relevance of changes in TET1 levels was demonstrated in an independent PCa cohort, in which low TET1 mRNA levels were significantly associated with worse metastases-free survival. We also demonstrate a strong reduction in hydroxymethylated DNA in tumor tissue in 27 of 41 cases. Furthermore, we report the first exploratory (h)MeDIP-Seq analyses of eight high-risk PCa samples. This reveals a large heterogeneity in hydroxymethylation changes in tumor versus non-tumor genomes which can be linked with cell polarity.

Improving education in primary care: development of an online curriculum using the blended learning model.

Standardizing the experiences of medical students in a community preceptorship where clinical sites vary by geography and discipline can be challenging. Computer-assisted learning is prevalent in medical education and can help standardize experiences, but often is not used to its fullest advantage. A blended learning curriculum combining web-based modules with face-to-face learning can ensure students obtain core curricular principles. This course was developed and used at The Case Western Reserve University School of Medicine and its associated preceptorship sites in the greater Cleveland area. Leaders of a two-year elective continuity experience at the Case Western Reserve School of Medicine used adult learning principles to develop four interactive online modules presenting basics of office practice, difficult patient interviews, common primary care diagnoses, and disease prevention. They can be viewed at (http://casemed.case.edu/cpcp/curriculum). Students completed surveys rating the content and technical performance of each module and completed a Generalist OSCE exam at the end of the course. Participating students rated all aspects of the course highly; particularly those related to charting and direct patient care. Additionally, they scored very well on the Generalist OSCE exam. Students found the web-based modules to be valuable and to enhance their clinical learning. The blended learning model is a useful tool in designing web-based curriculum for enhancing the clinical curriculum of medical students.

Practical experience with clinical cases has played an important role in supporting the learning of clinical reasoning. However, learning through practical experience involves complex processes difficult to be captured by students. This study aimed to examine the effects of a computer-based cognitive-mapping approach that helps students to externalize the reasoning process and the knowledge underlying the reasoning process when they work with clinical cases. A comparison between the cognitive-mapping approach and the verbal-text approach was made by analyzing their effects on learning outcomes. Fifty-two third-year or higher students from two medical schools participated in the study. Students in the experimental group used the computer-base cognitive-mapping approach, while the control group used the verbal-text approach, to make sense of their thinking and actions when they worked with four simulated cases over 4 weeks. For each case, students in both groups reported their reasoning process (involving data capture, hypotheses formulation, and reasoning with justifications) and the underlying knowledge (involving identified concepts and the relationships between the concepts) using the given approach. The learning products (cognitive maps or verbal text) revealed that students in the cognitive-mapping group outperformed those in the verbal-text group in the reasoning process, but not in making sense of the knowledge underlying the reasoning process. No significant differences were found in a knowledge posttest between the two groups. The computer-based cognitive-mapping approach has shown a promising advantage over the verbal-text approach in improving students' reasoning performance. Further studies are needed to examine the effects of the cognitive-mapping approach in improving the construction of subject-matter knowledge on the basis of practical experience.

Necrotizing Fasciitis in Aesthetic Surgery: A Review of the Literature.

2017-04-01

Necrotizing fasciitis (NF) is a rare, potentially fatal, infective complication that can occur after surgery. Diagnosis is still difficult and mainly based on clinical data. Only a prompt pharmacological and surgical therapy can avoid dramatic consequences. There are few reports regarding NF as a complication after aesthetic surgical procedures, and a systematic review still lacks. We have performed a systematic review of English literature on PubMed, covering a period of 30 years. Keywords used were "necrotising fasciitis" matched with "aesthetic surgery complications", "breast surgery", "mammoplasty", "blepharoplasty", "liposuction", "facelift", "rhinoplasty fasciitis", "arm lift", "thigh lift", "otoplasty" and "abdominoplasty fasciitis". No additional search and temporal limitation were set. Among 3782 papers concerning NF, only 18 were related to NF after an aesthetic surgical procedure. Liposuction was the most affected procedure, with buttocks and lower extremity the most involved anatomical regions. The majority of the infections were monomicrobial, promoted by Streptococcus pyogenes. In most cases, NF occurred within the third post-operative day with non-specific signs and symptoms. In 14 cases, a single or multiple surgical interventions were performed and survival was achieved in 11 patients. In case of infection after aesthetic surgery, we should always bear in mind NF. Clinical hallmarks still guide NF management. Because early signs and symptoms are usually non-specific, a strict clinical control is highly suggested. Once clinical suspicion is raised, prompt antibacterial therapy should be administered, followed by surgical debridement in case of ineffective response.

The pseudotumorous form of tuberculosis is a rare entity. Whatever its location, it can simulate neoplasia by its radiological and/or endoscopic appearances. We highlight the diagnostic difficulties associated with this type of presentation. We performed a retrospective study of inpatient records from 2003 to 2016 in the pneumology department of La Rabta Hospital to identify cases of thoracic tuberculous pseudo-tumor. Seventeen patients were identified. The median age was 41 years and their symptomatology was dominated by cough and general debility. All had abnormal radiology with 10 cases of suspect lesions. Fibre-optic bronchoscopy revealed endobronchial abnormalities in 11 cases. The median overall diagnostic delay was 97 days. The diagnosis was confirmed bacteriologically in five cases, histologically in 14 cases and based on clinical presumption in one case. The progression was favourable: 13 patients have been declared cured and four patients are still undergoing treatment. Making a positive diagnosis of thoracic tuberculous pseudotumour can be difficult, as bacteriological samples are often negative. This can lead to a significant delay in diagnosis and treatment.

A retrospective study was made of 75 patients with tuberculosis and tuberculous pleurisy who received medical care in our hospital from 2002 through 2006. Of the 75 patients, 9 were admitted as tertiary emergency cases, and 12 patients were admitted by ambulance as secondary emergency cases. We studied the reason for their emergency medical admission, and the process of diagnosing 21 patients as tuberculosis. In some cases, the reasons for emergency admission were cardiorespiratory arrest, loss of consciousness, and injury resulting from a traffic accident, not common symptoms of tuberculosis such as dyspnea, hemoptysis and bloody sputum. Chest radiographic findings of most patients showed tuberculosis, and other cases were likely to be diagnosed as tuberculosis from their medical history or back-ground such as being homeless, previous tuberculosis, and receiving for therapy of tuberculosis. It was not so difficult to diagnose our cases as tuberculosis, nevertheless we may have an unconscious patient with normal chest radiograph. These data suggest that any patients visiting the emergency room may possibly have tuberculosis even if they are without respiratory symptoms.

Tuberculosis in Pap samples with emphasis on LBC: Caught only when thought.

Despite being a commonly encountered infection, the clinical diagnosis of tuberculosis of the uterine cervix is elusive. Though a straightforward diagnosis on tissue sections, identification of typical features of tubercular infection on cervical Pap samples is challenging. In our experience, the infrequent pale staining collections of epithelioid cells are difficult to pick up on Pap stained smears, particularly LBC samples. In this series, 2 of the three samples were reported as atypical squamous cells of undetermined significance while 1 was reported as inflammatory at the initial diagnosis. Scattered Langhans' type giant cells may be seen as a subtle clue which should prompt the search for epithelioid cell granulomas. These cases may have a mass lesion clinically while no obvious signs of malignancy on the cervical samples. © 2017 Wiley Periodicals, Inc.

Paraphilia is a psychiatric disease that has been difficult to cure. However, recently developed therapeutic methods hold promise. The patient was a 20-yr-old male with chief complaints of continuous masturbation, genital exposure, and aggressive behavior that started 2 yr ago. We administered leuprorelin 3.6 mg intramuscular injection per month, a depot gonadotrophin-releasing hormone analogue, to this patient who a severe mentally retardation with paraphilia. The clinical global impression (CGI)-severity, CGI-improvement and aberrant behavior checklist were performed. After one month, we observed significant improvement in symptoms, such as decreases of abnormal sexual behavior and sexual desire. The GnRH analogues are suggested to be used as an alternative or supplementary therapeutic method for sexual offenders after clinical studies. Graphical Abstract PMID:25246754

MELAS syndrome (mitochondrial myopathy, encephalopathy, lactic acidosis, stroke-like episodes) is a rare, multisystem disorder which belongs to a group of mitochondrial metabolic diseases. As other diseases in this group, it is inherited in the maternal line. In this report, we discussed a case of a 10-year-old girl with clinical and radiological picture of MELAS syndrome. We would like to describe characteristic radiological features of MELAS syndrome in CT, MRI and MR spectroscopy of the brain and differential diagnosis. The rarity of this disorder and the complexity of its clinical presentation make MELAS patients among the most difficult to diagnose. Brain imaging studies require a wide differential diagnosis, primarily to distinguish between MELAS and ischemic stroke. Particularly helpful are the MRI and MR spectroscopy techniques.

Due to the low incidence of the Ewing’s Sarcoma (ES) family tumors, the available epidemiology is likely to be unreliable, and at present, there are no standard diagnostic or clinical guidelines outlining their management. This report describes a case of peripheral primitive neuroectodermal tumor (ES/pPNET) which initially mimicked cystic lesions, and describes a comparison between ES and ES/pPNET in the jaws by the World Health Organization classification. This review addressed 63 cases published in the English literature between 1950 and 2016. The majority of cases were ES. Both ES and ES/pPNET mimicked other benign entities such as traumatic, cystic and inflammatory lesions. The patients who died of their disease had a history of metastatic tumors, and primary tumor located in the mandible and maxilla for ES and ES/pPNET, respectively. The differentiation of the ES family tumors from other small blue-cell tumors may be difficult and requires familiarity with histological and immunohistochemical features. PMID:28438883

Possibilities of post-mortem diagnostics, including immunodiagnostics, in cases of sudden death due to anaphylactic and anaphylactoid reactions.

Postmortem diagnostics of anaphylactic and anaphylactoid reaction as the cause of death in cases of sudden deaths without witnesses, as well as those in which circumstances of sudden disease and then death are known, seems to be very difficult. This is caused by the lack of characteristic macro- or microscopic changes to internal organs resulting from a short, or even very short time, that elapses from the action of the etiological factor till death. In the above mentioned cases it is often impossible to establish univocally the cause of death, despite considering information on the cause of disease and its clinical symptoms. On the basis of 2 cases of sudden deaths resulted from the intake of hazel nuts, and the administration of contrast agent before radiological examination, the authors discuss the usefulness of postmortem determinations of tryptase and IgE in blood for diagnostics of deaths resulting from anaphylactic and anaphylactoid reaction, respectively.

Tuberculous brain abscess and subdural empyema in an immunocompetent child: Significance of AFB staining in aspirated pus

Tuberculous brain abscess and subdural empyema are extremely rare manifestations of central nervous system tuberculosis. Here, we report a case of an 11-year-old immunocompetent child who developed temporal lobe abscess and subdural empyema following chronic otitis media. A right temporal craniotomy was performed and the abscess was excised. The Ziehl Nielsen staining of the aspirated pus from the temporal lobe abscess yielded acid fast bacilli. Prompt administration of antituberculous treatment resulted in complete recovery of the child. Even though the subdural abscess was not drained, we presume that to be of tubercular aetiology. Ours is probably the first case of brain abscess and subdural empyema due to Mycobacterium tuberculosis reported in the same child. This case is being reported because of its rarity and to stress the importance of routine staining for tubercle bacilli in all cases of brain abscess, especially in endemic areas, as it is difficult to differentiate tuberculous from pyogenic abscess clinically as well as histopathologically.

Surveillance for incident asthma in the general population could provide timely information about asthma trends and new, emerging etiologic factors. We sought to determine the feasibility of an asthma incidence surveillance system using voluntary reporting of asthma by outpatient clinics and emergency departments (EDs). Voluntary reporting occurred from July 2002 through June 2006. We classified reported asthma based on a case definition adapted from one developed by the Council of State and Territorial Epidemiologists. We validated the case definition by having pulmonologists review data from participant interviews, medical record abstractions, and pulmonary function test (PFT) results. The positive predictive value (PPV) of meeting any of the case definition criteria for asthma was 80% to 82%. The criterion of taking at least one rescue and one controller medication had the highest PPV (97% to 100%). Only 7% of people meeting the incident case definition had a PFT documented in their medical record, limiting the usefulness of PFT results for case classification. Compared with pediatric participants, adult participants were more likely to be uninsured and to obtain asthma care at EDs. The surveillance system cost $5129 per enrolled person meeting the incident case definition and was difficult to implement in participating clinics and EDs because asthma reporting was not mandatory and informed consent was necessary. The project was useful in evaluating the case definition's validity and in describing the participants' characteristics and health-care use patterns. However, without mandatory reporting laws, reporting of incident asthma in the general population by clinicians is not likely to be a feasible method for asthma surveillance.

Only a small proportion of all paediatric fractures is caused by child abuse or neglect, especially in highly prevalent long bone fractures. It can be difficult to differentiate abusive fractures from non-abusive fractures. This article focuses on femoral fractures in young children. Based on three cases, this article presents a forensic evidence-based approach to differentiate between accidental and non-accidental causes of femoral fractures. We describe three cases of young children who were presented to the emergency department because of a suspected femur fracture. Although in all cases, the fracture had a similar location and appearance, the clinical history and developmental stage of the child led to three different conclusions. In the first two cases, an accidental mechanism was a plausible conclusion, although in the second case, neglect of parental supervision was the cause for concern. In the third case, a non-accidental injury was diagnosed and appropriate legal prosecution followed. Any doctor treating children should always be aware of the possibility of child abuse and neglect in children with injuries, especially in young and non-mobile children presenting with an unknown trauma mechanism. If a suspicion of child abuse or neglect arises, a thorough diagnostic work-up should be performed, including a full skeletal survey according to the guidelines of the Royal College of Radiologists and the Royal College of Paediatrics and Child Health. In order to make a good assessment, the radiologist reviewing the skeletal survey needs access to all relevant clinical and social information. PMID:26642309

Intrathecal drug delivery is known to be effective in alleviating cancer pain in patients for whom the conventional World Health Organization approach has proved insufficient. A multidisciplinary interventional cancer pain service was established in the West of Scotland in 2008 with the aim of providing a safe and effective intrathecal drug delivery service for patients with difficult-to-control cancer pain. The aim of the intrathecal drug delivery service is to improve pain scores as evaluated by pain scores before and after insertion of an intrathecal drug delivery device. Pain is monitored before and after intrathecal drug delivery implantation using the Brief Pain Inventory. Following implantation, pumps are refilled fortnightly and repeat Brief Pain Inventory assessments are undertaken. This prospective case series analyses change in Brief Pain Inventory domains for patients who had an intrathecal drug delivery implanted using a paired sample t-test. Data are presented from 2008-2013 for 22 patients receiving an intrathecal drug delivery system who experienced an immediate improvement in their pain that was both clinically and statistically significant. One week after insertion, the average pain score on the Brief Pain Inventory fell from 6.8 (pre-intrathecal drug delivery) to 3.0 (post-intrathecal drug delivery). Improvement in pain scores was sustained over a 6-month period. Evaluation of results of this case series shows that with the appropriate use of intrathecal drug delivery systems, patients with difficult-to-control cancer pain can benefit from effective pain relief for many months. © The Author(s) 2015.

Introduction: Laparoscopic cholecystectomy (LC) is very commonly performed surgical intervention. Acute or chronic cholecystitis, adhesions due to previous upper abdomen surgeries, Mirrizi’s syndrome and obesity are common clinical conditions that can be associated with difficult cholecystectomy. In this study, we evaluated and scored the patients with difficult surgical exploration during laparoscopic cholecystectomy. Material and Method: All patients who underwent LC from 2010 to 2015 were retrospectively rewieved. According to intraoperative findings DLC cases were described and classified. Class I difficulty: Adhesion of omentum majus, transverse colon, duodenum to the fundus of the gallbladder. Class II difficulty: Adhesions in Calot’s triangle and difficulty in dissection of cystic artery and cystic duct Class III difficulty: Difficulty in dissection of gallbladder bed (scleroathrophic gallbladder, hemorrhage from liver during dissection of gallbladder, chirotic liver). Class IV difficulty: Difficulty in exploration of gallbladder due to intraabdominal adhesions including technical problems. Results: A total of 146 patients were operated with DLC. The most common difficulty type was Class I difficulty (88 patients/60.2%). Laparoscopic cholecystectomy was converted to laparotomy in 98 patients. Operation time was found to be related with conversion to open surgery (P<0.05). Wound infection rate was also statistically higher in conversion group (P<0.05). The opertion time was found to be longest with Class II difficulty. Conversion rate to open surgery was also highest with Class II difficulty group. Conclusion: Class II difficulty characterized by severe adhesions in calot’s triangle is most serious problem among all DLC cases. They have longer operation time and higher conversion rate.

Pycodysostosis is a genetic autosomal rare disease with an incidence of 1:1.7 million births; the pathophysiology of the disease is related to mutation of cathepsin K gene. Sleep apnea, respiratory difficulties because of chest and oral abnormalities may cause a challenge to the anesthetist during intubation and/or mechanical ventilation. In this case report we will discuss a case of pycodysostosis with a difficult airway. PMID:25886438

Despite great therapeutic advancements in psoriasis, four notable difficult-to-treat areas including the scalp, nails, intertriginous (including genitals), and palmoplantar regions, pose a challenge to both physicians and patients. Localized disease of these specific body regions inflicts a significant burden on patients' quality of life and requires an adequate selection of treatments. Areas covered: This manuscript discusses appropriate therapies and important treatment considerations for these difficult-to-treat areas based on the available clinical data from the literature. Expert opinion: Clinical trials assessing therapies for the difficult-to-treat areas have been inadequate. With the first biological clinical trial for genital psoriasis pending publication, it is with hope that other biological agents will be evaluated for region-specific psoriasis. A greater understanding of the genetic and immunologic aspects of regional psoriasis, as well as identification of unique biomarkers, will further guide management decisions. For example, the recent discovery of the IL-36 receptor gene for generalized pustular psoriasis may prove valuable for other forms of psoriasis. Ultimately, identification of the most beneficial treatments for each psoriasis subtype and difficult-to-treat area will provide patients with maximal quality of life.

Primary lower-limb lymphoedema is a chronic, progressive and debilitating condition with a difficult management, especially in advanced cases (elephantiasis). Recently, autologous lymph node transplantation (ALNT) appears to be a promising treatment for extremity lymphoedema. A case of a double ALNT for an advanced primary lower-limb lymphoedema is here reported: a contralateral inguinal lymph node flap was transferred to the knee and, in a second surgery, a thoracic lymph node flap was transplanted to the inguinal region. Clinical outcomes at 5 months postoperatively are very satisfactory with reduction in limb circumferences and improvement in skin quality and social impairment.

2014-01-01

Parapharyngeal space tumors are known for having a difficult approach, misleading diagnosis and for representing a treatment challenge. Hemangiopericytomas account for less than 1% of all vascular neoplasms and 3% of all soft tissue sarcomas. Only 14 cases have been reported in the worldwide literature in this location. We present a case of a 44-year-old male who was referred for evaluation. A CT scan and MRI showed a large parapharyngeal mass of a possible salivary gland origin. The patient underwent a lateral cervicotomy associated with a transparotid-transmandibular approach, obtaining a vimentin-positive immunostaining tumor defining the diagnosis. The accurate management and prognosis of this type of neoplasm are provided by the definite diagnosis obtained by a correct histopathologic assessment. A high clinical suspicion is essential. © 2014 S. Karger AG, Basel.

Diffuse idiopathic hyperplasia of the sternocleidomastoid muscle in a child

2009-01-01

Unilateral diffuse or localized enlargement of the sternocleidomastoid muscle (SCM) is an event commonly seen in infancy, and is popularly known as ‘sternocleidomastoid tumor’. The condition, which usually spontaneously resolves with or without physiotherapy, is due to a hematoma following a difficult labor. The muscle regains its elasticity and complete function. In some infants it resolves with fibromatous changes in the muscle leading to shortening, fibrosis and finally culminating in torticollis. We describe a case of idiopathic diffuse enlargement of unilateral SCM in a 12-year-old child without any functional compromise or torticollis. The histopathological and clinical characteristics differentiating it from more commonly described sternocleidomastoid tumor or fibromatosis coli are described. We believe this is the first case report of idiopathic hyperplasia of SCM. PMID:19847086

Mycetoma is a chronic granulomatous infection that is difficult to treat, notably when due to fungi such as Scedosporium apiospermum. Recent antifungal agents could be an option, but cases are rarely reported, and none with posaconazole. Paradoxical responses, defined as initial clinical worsening despite appropriate treatment, are common in tuberculosis but rare in deep mycoses in non-immunocompromised hosts. Hence, paradoxical responses in context other than mycobacterial infection in an immunocompromised host could provide insights into the pathophysiology and the optimal strategy for treatment. We report the first case of a mycetoma caused by S. apiospermum with bone involvement treated with posaconazole, and the paradoxical response observed at the beginning of the treatment. As with mycobacterial infections, a paradoxical response in deep mycosis could represent the earliest marker of therapeutic efficacy.

The seeds from Lupinus mutabilis Sweet, also called "chocho", are an important part of the diet in several countries in South America. Prior to consumption, processing is required to remove toxic alkaloids. These alkaloids are known to have pharmacological properties as antiarrhythmics, antimuscarinics and hypoglycemics. We report a case in which a one-year-old male initially presented with altered mental status and respiratory distress and subsequently developed symptoms of anticholinergic toxicity, after ingesting a large amount of chocho seeds. In spite of going through a difficult clinical condition, the subject evolved favorably through receiving supportive treatment. The seeds from Lupinus mutabilis provide nutritional benefits when consumed, but people need to know their risks when these seeds are consumed without proper preparation.

Introduction Dental transposition and impaction are disorders related to ectopic eruption or failure in tooth eruption, which can affect child physical, mental and social development and may be difficult to be clinically solved. Methods We describe a case of transposition between the upper left canine and lateral incisor associated with impaction of the central incisor on the same side, in a 12-year-old patient. Conservative treatment involving surgical-orthodontic correction of transposed teeth and traction of the central incisor was conducted. Conclusion The option of correcting transposition and orthodontic traction by means of the segmented arch technique with devices such as cantilever and TMA rectangular wire loops, although a complex alternative, was proved to be esthetically and functionally effective.

Postoperative vision loss (POVL) following non-ocular surgery is a serious complication where the causes are not fully understood. Studies have identified several causes of POVL as well as risk factors and prevention strategies. POVL research is made difficult by the fact that cases are often subject to malpractice claims, resulting in a lack of public access to case reports. This literature review was conducted in order to identify legal issues as a major barrier to studying POVL and address how this affects current knowledge. Informed consent provides an opportunity to overcome legal challenges by reducing malpractice litigation through educating the patient on this outcome. Providing pertinent information regarding POVL during the informed consent process has potential to reduce malpractice claims and increase available clinical information.

Ankylosing spondylitis (AS) is a chronic inflammatory disease that affects the axial skeleton and evolves in stiffness followed by ankylosis and disability. However, it may be difficult to exactly establish the natural history of the disease and the influence of risk factors of progression, since most patients are treated with various pharmacologic or non-pharmacologic agents, which may potentially influence the natural progression of the disease. In this context, we report here a very interesting case of a 40 year old man, presented to our outpatient clinic, 28 years after the onset of AS. Previously for personal reasons, did not choose not to undergo any treatment. This case allows us to evaluate the natural radiological progression of the disease and the influence of predictive risk factors.

The Unexpected Ovarian Pregnancy at Laparoscopy: A Review of Management.

2017-01-01

Ovarian ectopic pregnancies are a rare occurrence; however the incidence is on the rise. Preoperative diagnosis remains difficult due to nonspecific clinical symptoms and USS findings. Most patients undergo diagnostic laparoscopy with subsequent surgical management. We present the case of a 32-year-old female who presented with vaginal bleeding and an unsited pregnancy, with a BhCG of 24693. Formal USS described unruptured right tubal ectopic with ovarian pregnancy being diagnosed at laparoscopy. A wedge resection was conducted to preserve ovarian function. Postoperative recovery was uneventful and BhCG levels returned to zero (nonpregnant) in an outpatient setting. Although laparoscopy remains the gold standard of diagnosis and treatment, in this case report we discuss benefits of early diagnosis for fertility conserving management, including nonsurgical options.
