We present a case of MEN 2B diagnosed in a 23 year-old patient on the basis of bilateral pheochromocytoma and medullary thyroid carcinoma. This young male patient also had multiple paragangliomas located along the spine, marfanoid features of body habitus and numerous mucosal neuromas of the oral cavity and intestinal ganglioneuromatosis. The patient was hospitalised several times between the ages of 11 and 14 due to heart rhythm disorders (tachycardia, multiple supraventricular beats) and pain in the precardiac area. Elevated blood pressure was not observed at that time. In 2010, the patient was admitted to hospital due to abdominal pain, nausea, vomiting and hypertension; bilateral adrenal tumours were then detected. The patient was referred to the Department of Endocrinology in Szczecin, with suspected pheochromocytoma in order to continue the diagnostic process. This resulted in the diagnosis of bilateral pheochromocytoma and medullary thyroid carcinoma. On the basis of the whole clinical picture, the diagnosis of MEN 2B was established and subsequently confirmed with genetic test results. Following the removal of adrenal tumours and thyroidectomy, the patient was referred to the Cancer Centre and Institute of Oncology in Gliwice for further treatment (X-ray therapy and further surgery due to recurrence of medullary carcinoma). This article presents a case of late MEN 2B diagnosis despite the presence of clinical symptoms suggestive of Multiple Endocrine Neoplasia observed from early childhood. 相似文献

This case report details the successful rehabilitation of an edentulous patient using a complete upper prosthesis and a lower implant retained overdenture. The provision of care was split between a specialist centre and a primary care setting. This approach reduced inconvenience to the patient. Modern surgical and prosthodontic techniques also reduced the total delivery time. After initial consultation a new set of complete dentures was prescribed with changes in design to the originals. The patient was also planned for placement of two mandibular implants to stabilise and retain the mandibular denture. The first line of treatment involved provision of a new set of dentures constructed by the patient's general dental practitioner. Dental implants were then placed in a specialist centre and the patient returned to the dental practice for attachment of the lower denture to the dental implants. The benefits and success of mandibular implant retained dentures are well documented. With delivery of the overdenture, the patient reported increased satisfaction with his prostheses which allowed him to eat a greater range of foods and enabled him to feel confident when speaking and socialising. 相似文献

Urine from a patient with cyclic neutropenia was found to contain a lymphopoietic activity that acts as a growth factor for human pre-B cells. This biologic activity was detectable during the week preceding, but not during, the period of neutropenia. This corresponded with a periodic excessive accumulation of pre-B cells in the marrow of this patient. Urine preparations were added to cultures of normal human bone marrow that had been depleted of B cells. Pre-B cells were generated in these cultures but not in cultures containing urine preparations from normal donors. Pre-B cells were also generated from bone marrow that had been depleted of 177.17+ cells and the majority of pre-B cells. This is the first report of a hemopoietic activity which affects human pre-B cells. This activity may represent a normal regulatory molecule that is periodically produced in excess in this patient. 相似文献

Myeloperoxidase (MPO; EC 1.11.1.7) plays an important role in the host defense mechanism against microbial diseases. The neutrophil disorder characterized by the lack of MPO activity, is speculated to be associated with a decreased level of immunity. A Japanese patient was identified with complete MPO deficiency through automated hematography. Neutrophil function analysis revealed that MPO activity was significantly diminished with slightly elevated superoxide production. Mutational analysis of the patient revealed a glycine to serine substitution (G501S) in the exon 9 region. This mutation was not detected in the 96 healthy controls analyzed. The amino acid substitution found may be responsible for the failure of mature MPO production in the patient. This is the first case of MPO deficiency of G501S missense mutation identified in a Japanese patient. 相似文献

Mitochondrial ND5 gene variation associated with encephalomyopathy and mitochondrial ATP consumption 总被引:1,自引:0,他引:1
McKenzie M Liolitsa D Akinshina N Campanella M Sisodiya S Hargreaves I Nirmalananthan N Sweeney MG Abou-Sleiman PM Wood NW Hanna MG Duchen MR 《The Journal of biological chemistry》2007,282(51):36845-36852
Mitochondrial encephalomyopathy and lactic acidosis with strokelike episodes (MELAS) is a severe young onset stroke disorder without effective treatment. We have identified a MELAS patient harboring a 13528A-->G mitochondrial DNA (mtDNA) mutation in the Complex I ND5 gene. This mutation was homoplasmic in mtDNA from patient muscle and nearly homoplasmic (99.9%) in blood. Fibroblasts from the patient exhibited decreased mitochondrial membrane potential (Deltapsim) and increased lactate production, consistent with impaired mitochondrial function. Transfer of patient mtDNA to a new nuclear background using transmitochondrial cybrid fusions confirmed the pathogenicity of the 13528A-->G mutation; Complex I-linked respiration and Deltapsim were both significantly reduced in patient mtDNA cybrids compared with controls. Inhibition of the adenine nucleotide translocase or the F1F0-ATPase with bongkrekic acid or oligomycin caused a loss of potential in patient mtDNA cybrid mitochondria, indicating a requirement for glycolytically generated ATP to maintain Deltapsim. This was confirmed by inhibition of glycolysis with 2-deoxy-D-glucose, which caused depletion of ATP and mitochondrial depolarization in patient mtDNA cybrids. These data suggest that in response to impaired respiration due to the mtDNA mutation, mitochondria consume ATP to maintain Deltapsim, representing a potential pathophysiological mechanism in human mitochondrial disease. 相似文献

BACKGROUND: We report a case of a patient with apparent resistance to local anesthetics. While similar cases of failure of regional anesthetics are often attributed to technical failure, the overall clinical presentation and history of this patient suggests a true resistance to local anesthetics. CASE PRESENTATION: This patient presented for elective cesarean section and the decision for regional anesthesia was made. While attempting to place an epidural, the patient failed to achieve adequate skin analgesia despite multiple attempts at local infiltration. When a spinal was ultimately placed, sensory or motor blockade was not obtained despite no evidence of technical problems with technique. Further questioning revealed multiple prior episodes of local anesthetic failure in this patient. CONCLUSIONS: While the failure rate of spinal anesthesia has been shown range from 4-13% and is often attributed to technical failure, elements of this particular case suggest a true resistance to local anesthetics. 相似文献

Two cases of the acute disseminated intravascular coagulation (DIC) are presented. DIC in the first case was diagnosed in healthy pregnant woman without any obstetric pathology. This patient recovered completely. The acute DIC in another patient preceded the acute promyelocytic leukemia. The patient died despite a control of DIC. DIC therapy included antifibrinolytic agents and additionally corticoids in pregnant patient. Heparin was not administered because of post partum period and foreseen cytostatic therapy in the leukemic patient. 相似文献

ObjectiveTo describe the first reported case of acute pancreatitis in a patient receiving vildagliptin.MethodsWe present the clinical, biochemical, and radiographic findings of the study patient.ResultsA 61-year-old woman who presented with severe abdominal pain was found to have acute pancreatitis. This occurred 5 weeks after the commencement of vildagliptin, a dipeptidyl-peptidase 4 inhibitor, for the treatment of type 2 diabetes mellitus. The patient’s pancreatic enzymes were elevated (amylase, 1205 U/L; lipase, 8846 U/L), and abdominal computed tomography demonstrated diffuse pancreatic swelling, cyst formation, and necrosis in the body of the pancreas. In the absence of an identifiable cause for the patient’s pancreatitis, vildagliptin was considered a potential trigger. The patient recovered after vildagliptin therapy was ceased.ConclusionsAlthough incretin-based therapy effectively treats type 2 diabetes mellitus, emerging reports of acute pancreatitis in patients receiving sitagliptin and exenatide have prompted the US Food and Drug Administration to issue an alert on these drugs. This appears to be the first reported case of acute pancreatitis in a patient receiving vildagliptin, and it supports the possibility that acute pancreatitis may be a rare effect of incretin-based therapy.(Endocr Pract. 2011;17:e48-e50) 相似文献

The purpose of this case study is to demonstrate the treatment of patella-femoral knee pain in an adolescent female athlete with emphasis on neuromuscular training of the knee and hip in synergy movement strategies. A 1.67-m, 61.5-kg, 15-year-old woman athlete reported to rehabilitation with the complaint of a 1-year history of bilateral knee pain. The patient noted that the symptoms were exacerbated with any sports-specific training. The patient played softball as an infielder. The athlete was referred by her family practice physician. After the patient was assessed, a clinical hypothesis was generated. It was thought that neuromuscular dysfunction of the hips and knees was causing faulty knee mechanics. These abnormal mechanics were presenting as patella-femoral knee pain. Initially, the athlete was assigned a home exercise program of side-lying hip abduction and lateral step-downs. At her first follow-up appointment, she noted increased symptoms that were aggravated with her home program. Upon inspecting her exercise technique, faulty step-down mechanics were contributing to her symptoms. Step-downs were discontinued, and the patient was instructed in and performed a chair squatting exercise, which was added to her home program. At her next follow-up, the patient noted being asymptomatic for 2 days. Her exercises were increased in intensity to include a Stairmaster and hip abduction and adduction on a 4-way hip machine. Eventually, over her treatment course, perturbation and proprioceptive training were initiated. By the sixth visit, the patient reported no symptoms and felt comfortable with self-management. A phone interview 3 months later indicated that the patient had no recurrent symptoms and was participating in sports without difficulty. This case demonstrates effectiveness of using hip and knee joint synergy to treat patella-femoral pain (PFP). The use of this synergy promotes proper patella–femoral alignment and improved knee mechanics. This case also is unique in the lack of physical agents and taping used to improve the patient's condition. It reinforces how exercise technique can carry over to functional athletic activities. This study provides a case for the use of hip and knee mechanical retraining in the treatment of PFP in adolescent female athletes who do not exhibit abnormal foot mechanics in weight bearing. It is important that sports medicine professionals be aware of these treatment options and are able to use them to correct these deficits in order to facilitate return to training and competition as quickly and safely as possible. 相似文献

Culture is an essential variable of diagnosis and treatment. A cultural perspective draws attention to the social context
within which symptoms arise, are given meaning, and are managed. Ethno-cultural work on illness narratives suggests that most
people can provide culturally-based explanations for their symptoms. While these explanations are inconsistent with biomedical
theory, they relieve patient distress by allowing the patient to create meaning for symptoms. Exploring the characteristics,
context, and antecedents of the symptoms enables the patient to convey them to the clinician who may have a divergent explanation
of sickness. This case study uses the Outline for Cultural Formulation of the DSM-IV created for clinicians to elicit a narrative
account of the illness experience from the patient. Our study examines how the patient, a Laotian used social indignation
(“Kwam khem keuang”) as an explanatory model for his ailment. He was diagnosed with post-traumatic stress disorder after having undergone a
traumatic amputation. In the process of explaining his illness through a cultural idiom, the patient was able to reveal both
personal and collective meaning of repressed anger and frustration, expressing them in a context that was acceptable to him.
This cultural idiom allowed the patient to reflect upon the structure of the health care system and the specific context in
which symptoms and their possible origins are recounted and explored. It also clarified to the treating clinicians some categories
of experience and causal explanations that did not fit easily with western biomedical and psychiatric understanding. The case
study illustrates how a cultural approach to illness from the patient’s perspective offers a reflexive stance on the clinician–patient
interaction that allows for better patient care. 相似文献

This report concerns two new mutations in the sterol 27-hydroxylase gene in two patients with cerebrotendinous xanthomatosis
(CTX). In a Surinam-Creole patient (patient A), a G deletion on position cDNA 546/547 in exon 3 led to a frameshift and the
introduction of a premature termination codon. In a Dutch patient (patient B), a C→T transition at position 496 in exon 3
also led to a premature termination codon. Patient A was homozygous for the mutation, whereas patient B was compound heterozygous,
a C→T transition also being found in exon 6 at position 1204. The two new mutations were confirmed by restriction analysis
with the restriction enzymes FokI and MaeI, respectively.

Although numerous studies provide evidence that active patient engagement with health care providers improves critical outcomes such as medication adherence, very few of these have been done in low resource settings. In Namibia, patient education and empowerment trainings were conducted in four antiretroviral (ART) clinics to increase patient engagement during patient-provider interactions. This qualitative study supplements findings from a randomized controlled trial, by analyzing data from 10 in-depth patient interviews and 94 training evaluation forms. A blended approach of deductive and inductive coding was used to understand training impact. Findings indicated the trainings increased patients’ self-efficacy through a combination of improved HIV-related knowledge, greater communication skills and enhanced ability to overcome complex psychosocial barriers, such as fear of speaking up to providers. This study suggests patient empowerment training may be a powerful method to engage HIV patients in their own care and treatment. 相似文献

The purpose of the present study was to analyze the clinical phenotypes of a girl with oculo-facio-cardio-dental(OFCD)syndrome and to identify the potential pathogenic mutation responsible for her disease. The patient underwent detailed clinical examinations and phenotype data were collected over a follow-up period of 9 years. Mutation analysis of the candidate gene BCOR was performed with polymerase chain reaction and Sanger sequencing. BCOR of 60 unrelated normal individuals were also sequenced as a control group. Clinical phenotyping and follow-up study results indicate that this patient had multiple system anomalies including ocular, facial, cardiac, dental, and limb malformations. In addition, papilloma of the choroid plexus was identified, which represents the first report of this phenotype in an OFCD patient. A novel deletion mutation, c.1296 delT in exon4 of the BCOR gene, was identified in this patient and was not found in her parents or in 60 normal unrelated individuals. This deletion was a frameshift mutation and is proposed to encode a premature stop codon, thus producing a truncated protein. Our patient fitted the diagnostic criteria for OFCD syndrome and we report the first papilloma of the choroid plexus in an OFCD patient, expanding the recognized phenotypic spectrum of this disease. Meanwhile, we identified a novel deletion mutation that may cause OFCD syndrome. 相似文献

Focal segmental glomerulosclerosis (FSGS) is the most frequent acquired renal condition resulting in end stage kidney disease in children. We describe a cell therapy treatment with human allogeneic bone marrow mesenchymal stem cells (MSC) in a 13-year-old patient developing recurrent FSGS after renal transplantation, which was not responding to conventional therapy.This treatment relied on the following measurements:clinical and laboratory evaluation of renal function, proteome array, biopsy, short tandem repeat assay.Before MSC treatment, the patient needed weekly plasmapheresis to achieve proteinuria-to-creatininuria ratio below 5. After three MSC infusions without adverse events, the patient has a stable renal function and the proteinuria target was reached without plasmapheresis. In addition, some circulating inflammatory factors decreased and their levels were still low after one year.This is the first report of an MSC treatment in an FSGS patient. Even though different factors may have contributed to the clinical results, after MSC infusion a stable reduction in the serum level of several inflammatory factors has been registered and the patient does not need anymore plasmapheresis to keep proteinuria under control.In addition, this encouraging single case let us identify some putative efficacy biomarkers that could be of clinical interest in chronic kidney diseases. 相似文献

New equipment was developed to enable an aphasic quadriplegic patient to communicate with other people. The patient was completely quadriplegic except for slight movement in the right hand and minimal movement of the left fingers. The equipment translated Morse code, which the patient had to learn, into either (1) a visual display to communicate with visitors, or (2) an electric typewriter input to permit correspondence. This case demonstrates how properly applied research can yield results of value in ameliorating the lot of patients with major physical afflictions or crippling illnesses. 相似文献

Scoliosis is a 3D deformation of the spine and rib cage. For severe cases, surgery with spine instrumentation is required to restore a balanced spine curvature. This surgical procedure may represent a neurological risk for the patient, especially during corrective maneuvers. This study aimed to computationally simulate the surgical instrumentation maneuvers on a patient-specific biomechanical model of the spine and spinal cord to assess and predict potential damage to the spinal cord and spinal nerves. A detailed finite element model (FEM) of the spine and spinal cord of a healthy subject was used as reference geometry. The FEM was personalized to the geometry of the patient using a 3D biplanar radiographic reconstruction technique and 3D dual kriging. Step by step surgical instrumentation maneuvers were simulated in order to assess the neurological risk associated to each maneuver. The surgical simulation methodology implemented was divided into two parts. First, a global multi-body simulation was used to extract the 3D displacement of six vertebral landmarks, which were then introduced as boundary conditions into the personalized FEM in order to reproduce the surgical procedure. The results of the FEM simulation for two cases were compared to published values on spinal cord neurological functional threshold. The efficiency of the reported method was checked considering one patient with neurological complications detected during surgery and one control patient. This comparison study showed that the patient-specific hybrid model reproduced successfully the biomechanics of neurological injury during scoliosis correction maneuvers. 相似文献

ObjectiveTo describe the effects of an infusion of zoledronic acid in a patient with Paget disease of bone (PD) who had been treated unsuccessfully with several other bisphosphonates.MethodsThe patient’s treatment history is described, and his response to various bisphosphonates, including zoledronic acid, is discussed.ResultsThe patient was a 61-year-old man when a diagnosis of PD was made on the basis of an elevated serum alkaline phosphatase (ALP) level of 391 U/L (reference range, 45 to 135). Pagetic bone changes were noted on bone scan and x-ray examinations. Treatment with etidronate had no effect on ALP levels. This intervention was followed by 2 courses of intravenous therapy with pamidronate, which decreased ALP levels by 57% and 55% without inducing a remission. Subsequent oral treatment with alendronate and then risedronate yielded unsustained biochemical remissions of 6 months each. Most recently, therapy with an infusion of 5 mg of zoledronic acid induced a remission that is thus far 20 months in duration. With this therapy, the patient has experienced no side effects, and he has noted a decrease in bone pain.ConclusionThis case study shows that a patient with PD who received successive treatments with several bisphosphonates with inadequate responses or only brief remissions was more effectively treated with a single 5-mg infusion of zoledronic acid. This patient’s therapeutic responses illustrate the relative efficacy of available bisphosphonates and the potential for longer-lasting remissions with zoledronic acid in patients with PD.

We identified a patient with the Brugada syndrome and frequent episodes of the traumatic syncope. This patient presented with alternating ST-segment elevation in the right precordial and the high lateral leads. The signal-averaged ECG was positive for the late potentials and electrophysiology study revealed no inducible supraventricular or ventricular tachycardias. Because of the frequent traumatic syncope, a dual-chamber implantable cardioverter-defibrillator was implanted. This report suggests that the Brugada syndrome may have different electrocardiographic presentations within a single individual over a short period of time. The significance of these changes needs to be assessed in a prospective long term study. 相似文献

This paper describes two cases of eyelid paracoccidioidomycosis (South American blastomycosis) in which it was the first signal
of the disease. In both cases the first clinical diagnosis made was not a fungal infection, but a neoplastic disease that
was not confirmed by the pathology study. In the first patient we suspected a primary infection on the eyelid, because there
was no other systemic signs of the disease, and in the second patient we noted a very advanced pulmonary lesions caused by
the Paracoccidioides brasiliensis. We believe that, in endemic areas, the histopathological study should be made before every
excisional procedures to avoid unnecessary palpebral mutilation.

Summary Metachromatic leukodystrophy is a lysosomal storage disorder caused by the deficiency of arylsulfatase A. Examination of the arylsulfatase A gene in a patient suffering from late infantile metachromatic leukodystrophy revealed an 11-bp deletion in exon 8. Although this allele produces normal amounts of ASA mRNA, no arylsulfatase A cross-reacting material could be detected in cultured fibroblasts from the patient. The patient was found to be a compound heterozygote, the other allele is also known to generate no ASA polypeptides. This patient is another example where absence of ASA polypeptides correlates with the severe late infantile form of metachromatic leukodystrophy. 相似文献
