Recessive multiple epiphyseal dysplasia (rMED) with homozygosity for C653S mutation in the DTDST gene - phenotype, molecular diagnosis and surgical treatment of habitual dislocation of multilayered patella: case report.

BACKGROUND: Multiple epiphyseal dysplasia (MED) is one of the more common generalised skeletal dysplasias. Due to its clinical heterogeneity diagnosis may be difficult. Mutations of at least six separate genes can cause MED. Joint deformities, joint pain and gait disorders are common symptoms. CASE PRESENTATION: We report on a 27-year-old male patient suffering from clinical symptoms of autosomal recessive MED with habitual dislocation of a multilayered patella on both sides, on the surgical treatment and on short-term clinical outcome. Clinical findings were: bilateral hip and knee pain, instability of femorotibial and patellofemoral joints with habitual patella dislocation on both sides, contractures of hip, elbow and second metacarpophalangeal joints. Main radiographic findings were: bilateral dislocated multilayered patella, dysplastic medial tibial plateaus, deformity of both femoral heads and osteoarthritis of the hip joints, and deformity of both radial heads. In the molecular genetic analysis, the DTDST mutation g.1984T > A (p.C653S) was found at the homozygote state. Carrier status was confirmed in the DNA of the patient's parents. The mutation could be considered to be the reason for the patient's disease. Surgical treatment of habitual patella dislocation with medialisation of the tibial tuberosity led to an excellent clinical outcome. CONCLUSIONS: The knowledge of different phenotypes of skeletal dysplasias helps to select genes for genetic analysis. Compared to other DTDST mutations, this is a rather mild phenotype. Molecular diagnosis is important for genetic counselling and for an accurate prognosis. Even in case of a multilayered patella in MED, habitual patella dislocation could be managed successfully by medialisation of the tibial tuberosity.

A análise dos fatores de risco de quedas nos idosos evidência a necessidade de desenvolvimento de novas estratégias modificadoras dos ambientes e componentes intrínsecos.

Chylothorax in children: guidelines for diagnosis and management.

STUDY OBJECTIVE: To establish guidelines for the diagnosis and management of chylothorax in children. DESIGN: Retrospective study. PATIENTS: Fifty-one patients with a diagnosis of chylothorax. Twelve patients were excluded because of incomplete data or incorrect diagnosis. The following parameters were analyzed: triglyceride level, total cell number, and lymphocyte percentage; amount of pleural effusion on day of diagnosis, day 5, and day 14; and total time of pleural effusion. Prospectively, the same parameters were analyzed in a control group of 10 patients with pleural drainage. INTERVENTION: Patients with chylothorax were treated primarily with fat-free oral nutrition; if chyle did not stop, total parenteral nutrition with total enteric rest was started. If conservative therapy was not successful, pleurodesis was performed. RESULTS: In children with chylothorax triglyceride, triglyceride content ranged from 0.56 to 26.6 mmol/L; all values except one were > 1.1 mmol/L. In 36 of 39 patients (92%), the cell count was > 1,000 cells/microL. In 33 of 39 patients (85%), lymphocytes were > 90%. In patients without chylothorax triglyceride, triglyceride levels ranged from 0.1 to 0.71 mmol/L (median, 0.38 mmol/L) and cell count was from 20 to 1400 cells/microL (median, 322 cells/microL), with a maximum of 60% lymphocytes. With fat-free nutrition, chyle disappeared in 29 of 39 patients. Five patients died, and five required pleurodesis. CONCLUSIONS: Pleural effusion in children is chyle when it contains > 1.1 mmol/L triglycerides (with oral fat intake) and has a total cell count > or 1,000 cells/microL, with a lymphocyte fraction > 80%. Chylous effusions usually last long; however, after 6 weeks, the majority of the effusions (29 of 39 patients) had ceased. Late surgical interventions reduce the number of thoracotomies substantially, but can lead to very long hospitalization times. Early surgical interventions (after < 3 weeks) lead to a high number of thoracotomies, but certainly reduce hospitalization time.

Syndrome de l'intestin irritable: un diagnostic d'exclusion. [Irritable bowel syndrome: an exclusion diagnosis?].

The irritable bowel syndrome has been considered a diagnosis of exclusion and multiple diagnostic procedures were often performed in order to exclude an organic disorder. Nowadays, studies show that in young patients, who match the clinical criteria of irritable bowel syndrome and show no alarm features, the prevalence of underlying organic disorders is low, or at least not higher than in the general population. Based on these findings, current recommendations suggest that no extra diagnostic tests have to be performed in those patients, apart from the serological tests in search of celiac disease, which are recommended for patients presenting an irritable bowel syndrome with diarrhea or a mixed-type irritable bowel syndrome.

The postmortem diagnosis of alcoholic ketoacidosis.

AIMS: The aim of this article is to review the forensic literature covering the postmortem investigations that are associated with alcoholic ketoacidosis fatalities and report the results of our own analyses. METHODS: Eight cases of suspected alcoholic ketoacidosis that had undergone medico-legal investigations in our facility from 2011 to 2013 were retrospectively selected. A series of laboratory parameters were measured in whole femoral blood, postmortem serum from femoral blood, urine and vitreous humor in order to obtain a more general overview on the biochemical and metabolic changes that occur during alcoholic ketoacidosis. Most of the tested parameters were chosen among those that had been described in clinical and forensic literature associated with alcoholic ketoacidosis and its complications. RESULTS: Ketone bodies and carbohydrate-deficient transferrin levels were increased in all cases. Biochemical markers of generalized inflammation, volume depletion and undernourishment showed higher levels. Adaptive endocrine reactions involving insulin, glucagon, cortisol and triiodothyronine were also observed. CONCLUSIONS: Metabolic and biochemical disturbances characterizing alcoholic ketoacidosis can be reliably identified in the postmortem setting. The correlation of medical history, autopsy findings and biochemical results proves therefore decisive in identifying pre-existing disorders, excluding alternative causes of death and diagnosing alcoholic ketoacidosis as the cause of death.

The discourse of health managers on aspects related to the delay in tuberculosis diagnosis

The aim of this study was to analyze the discourse of health managers on aspects related to delay in tuberculosis diagnosis. This was a qualitative research study, conducted with 16 Family Health Unit managers. The empirical data were obtained through semi-structured interviews. The analysis was based on the theoretical framework of the French school of discourse analysis. According to the managers’ statements, the delay in tuberculosis diagnosis is related to patient and health service aspects. As for patient aspects, managers report fear, prejudice and lack of information as factors that may promote a delayed diagnosis. Regarding health service aspects, structural problems and lack of professional skills were reported. The discourse of managers should be considered to qualify tuberculosis control actions and to prevent delays in diagnosis.

Content validation of the nursing diagnosis Nausea

This study aimed to evaluate the content validity of the nursing diagnosis of nausea in the immediate post-operative period, considering Fehring’s model. Descriptive study with 52 nurses experts who responded an instrument containing identification and validation of nausea diagnosis data. Most experts considered the domain 12 (Comfort), Class 1 (Physical Comfort) and the statement (Nausea) adequate to the diagnosis. Modifications were suggested in the current definition of this nursing diagnosis. Four defining characteristics were considered primary (reported nausea, increased salivation, aversion to food and vomiting sensation) and eight secondary (increased swallowing, sour taste in the mouth, pallor, tachycardia, diaphoresis, sensation of hot and cold, changes in blood pressure and pupil dilation). The total score for the diagnosis of nausea was 0.79. Reports of nausea, vomiting sensation, increased salivation and aversion to food are strong predictors of nursing diagnosis of nausea.

Prevalence of nursing diagnosis of fluid volume excess in patients undergoing hemodialysis

Objective: To identify the prevalence of nursing diagnosis of fluid volume excess and their defining characteristics in hemodialysis patients and the association between them. Method: Cross-sectional study conducted in two steps. We interviewed 100 patients between the months of December 2012 and April 2013 in a teaching hospital and one hemodialysis clinic. The inference was performed by diagnostician nurses between July and September 2013. Results: The diagnostic studied was identified in 82% of patients. The characteristics that were statistically associated: bounding pulses, pulmonary congestion, jugular vein distention, edema, change in electrolytes, weight gain, intake greater than output and abnormal breath sounds. Among these, edema and weight gain had the highest chances for the development of this diagnostic. Conclusion: The analyzed diagnostic is prevalent in this population and eight characteristics presented significant association.


La néphropathie ischémique par athérosclérose aortorénale : diagnostic [Atherosclerotic renal artery disease diagnosis update].

Atherosclerotic renal artery disease represents a cause of which little is known but not a cause to be neglected for hypertension and renal insufficiency. Even though its occurrence remains badly defined, atherosclerotic renal artery disease is constantly on the rise due to the aging population, the never prevailing hypertension and diabetes mellitus. This review aims to give a clinical profile of patients presenting with atherosclerotic renal artery disease and to discuss, in the light of study results, which diagnostic evaluation should be used considering the sequence and the benefit and risk of each in order to initiate a personalized treatment. Patients affected by atherosclerotic renal artery disease are likely to have more complications and more extensive target-organ damage than patients without renal artery stenosis. The evolution of the atherosclerotic renal artery disease is in general slow and progressive. Nevertheless, certain clinical cases manifest themselves with the onset of acute renal failure bought upon by the administration of blockers of the rennin-angiotensin-aldosterone system, or by some other causes responsible for a sudden drop in renal plasma flow (e.g., thrombosis of the renal artery). The relationship between atherosclerotic renal artery disease and atherosclerosis is complex, and mediators implicated in the pathophysiology of renovascular disease may also contribute to the progression of cardiovascular damage. An early assumption of the atherosclerotic renal artery stenosis is warranted to determine the adapted treatment (i.e., medical treatment, revascularisation...) just as the assumption and the correction of the more general cardiovascular risk factors.

Nursing diagnosis sedentary lifestyle in individuals with hypertension: an analysis of accuracy

Objective Assessing the accuracy of the defining characteristics (DC) of the nursing diagnosis Sedentary Lifestyle (SL) in people with hypertension. Method A cross-sectional study carried out in a referral center in the outpatient care of people with hypertension and diabetes, with a sample of 285 individuals. The form used in the study was designed from operational definitions constructed for each DC of the diagnosis. Four nurses with training to carry out diagnostic inferences did the clinical assessment for the presence of SL. Results The prevalence of SL was 55.8%. Regarding measures of accuracy, the main DC for SL was chooses a daily routine lacking physical exercise, with sensitivity of 100% and specificity of 84.13%. Two DC stood out in the logistic regression, namely: reports preference for activities low in physical activity and poor performance in instrumental activities of daily living (IADL). Conclusion The results allowed identifying the best clinical indicators for SL in hypertensive adults.
