Thyroid Microcalcifications in the Absence of Identifiable Nodules and Their Association With Thyroid Cancer.

OBJECTIVES: To determine ultrasound (US) and clinical findings of thyroid microcalcifications in the absence of a nodule and their association with the risk of malignancy. METHODS: The Institutional Review Board approved a 5-year retrospective study. Twenty-one patients with clustered or scattered thyroid microcalcifications in the absence of nodules on US images who underwent fine-needle aspiration biopsies (FNABs) were included. Demographic and clinical data, US findings, and pathologic results were registered. Patients with a suspicion of malignancy or papillary thyroid carcinoma (PTC) on FNAB underwent thyroidectomy. Patients with benign results on FNAB underwent clinical and US surveillance. RESULTS: The mean age of the 21 patients was 33.2 years (29.5 years in patients with PTC patients and 39.4 years in those with benign findings; P = .034). Eleven of 21 patients had clustered microcalcifications (9 had cancer), and 10 of 21 patients had scattered microcalcifications (4 of 10 had cancer; P = 0.063). Sixty-two percent of the patients had FNAB findings that were suspicious for cancer or had a diagnosis of cancer. Eleven of 13 patients had surgical thyroidectomy performed in our institution; in all cases, Hashimoto thyroiditis was confirmed. Univariate and multivariate analysis showed that only age was significant (odds ratio, 0.9; P < .05). CONCLUSIONS: Our study suggests that the presence of thyroid microcalcifications without a nodule is suspicious for PTC. We found that both patterns were suspicious for PTC, particularly in young patients. Special concern arises for those clustered microcalcifications on a background of Hashimoto thyroiditis.

[Prognostic value of granular pattern of growth hormone secreting tumors]. / Caracterización de tumores secretores de hormona de crecimiento de acuerdo al patrón granular y su rol en el pronóstico.

BACKGROUND: Classification of growth hormone (GH) - secreting tumors by the granular pattern might predict their clinical behavior in acromegalic patients. There are several other prognostic factors. AIM: To compare the features at presentation and cure rates of patients with GH secreting tumors according to the granular pattern, and to define independent prognostic factors for surgical treatment in these patients. MATERIAL AND METHODS: A retrospective, observational study of 85 active acromegalic patients surgically treated in two medical centers. RESULTS: Seventy-four patients (87%) were classified as having densely granulated (DG) and 11 (13%) as sparsely granulated (SG) tumors. The latter were less active biochemically, had a higher rate of macroadenoma and cavernous sinus invasion and had a lower rate of biochemical cure than the DG group. Several characteristics were associated with disease persistence but only age (Odds ratio (OR) = 0.93) and cavernous sinus invasion (OR = 21.7) were independently associated in the logistic regression model. CONCLUSIONS: The sparsely granulated pattern is associated with a more aggressive behavior, but the main determinants of prognosis are age and cavernous sinus invasion.

Depressive symptoms are associated with higher morning plasma cortisol in primary care subjects.

BACKGROUND: Cortisol dysregulation has a potential role in depression. AIM AND METHODS: We evaluated depressive symptoms using the Hamilton Rating Scale for Depression in 48 primary care subjects without history of previous or current depression and its association with cortisol dysregulation (morning plasma cortisol, 24-hour urinary free cortisol and cortisol metabolites). Presence of metabolic syndrome and inflammatory parameters were also assessed. RESULTS: Hamilton Rating Scale for Depression correlated significantly with morning cortisol, but not with urinary free cortisol or metabolites. A significant increase in morning cortisol by Hamilton groups (asymptomatic ≤8; mild to moderate: 9-18; moderate to severe: ≥19) was observed even when adjusted by age/gender. We observed no association of depressive symptoms with metabolic or inflammatory parameters. CONCLUSION: Depressive symptoms in primary care subjects not consulting for their mood are associated with higher morning plasma cortisol, but not urinary cortisol or its metabolites. These observations suggest that systemic hypercortisolism and related metabolic disorders are not observed in mild/initial states of depressive disorders.

Aggressive tumors and difficult choices in acromegaly.

PURPOSE: The current article looks at some of the factors associated with pituitary adenomas displaying unusually aggressive biological and clinical behaviour in patients with acromegaly. METHODS: This was a retrospective, narrative review of previously published evidence chosen at the authors' discretion and presented from the perspective of a Latin American case study. FINDINGS AND CONCLUSIONS: Although most pituitary tumors in acromegalic patients are benign and non-aggressive many can behave more aggressively, compromising local surrounding structures. These lesions tend to respond poorly to somatostatin analogs, have a higher risk of recurrence after surgery and, thus, a worse prognosis. Patients with more aggressive tumors constitute a particular challenge, as they often require several therapeutic approaches and may be difficult to manage, especially when options are restricted due to limited resources.

The role of primary pharmacological therapy in acromegaly.

BACKGROUND AND OBJECTIVES: Primary pharmacological therapy may be the only viable treatment option for many patients with acromegaly, especially those presenting with advanced disease with large inoperable tumors. Long-acting somatostatin analogs are currently the first-line treatment of choice in this setting, where they provide biochemical control and reduce tumor size in a significant proportion of patients. We herein present a brief overview of the role of primary pharmacological therapy in the treatment of acromegaly within the context of Latin America and support this with a representative case study. CASE DESCRIPTION: A 20 year old male presented with clinical and biochemical evidence of acromegaly. The glucose-suppressed growth hormone (GH) was 5.3 µg/L, his insulin-like growth factor-1(IGF-1) was 3.5 times the ULN and serum prolactin greater than 4,000 µg/L. Pituitary MRI revealed a large and invasive mass, extending superiorly into the optic chiasm and laterally into the left cavernous sinus. He was treated with a combination of octreotide and cabergoline with remarkable clinical improvement, normalization of GH and IGF-1 values and striking shrinkage of the adenoma. CONCLUSION: This case illustrates how effective the pharmacological therapy of acromegaly can be and yet at the same time, raises several important issues such as the need for life-long treatment with costly medications such as the somatostatin analogs. Access to these agents may be limited in regions where resources are restricted and clinicians face challenges in order to make the most efficient use of available options.

[Selective use of glucocorticoids during the perioperative period of transsphenoidal surgery for pituitary tumors]. / Criterios para la indicación selectiva de glucocorticoides en pacientes con tumores hipofisiarios sometidos a cirugía transesfenoidal.

BACKGROUND: There is consensus in promoting the selective use of glucocorticoids (GC) in the peri-operative period of transsphenoidal surgery (TE) for pituitary adenomas (PA). AIM: To evaluate the safety of a selective glucocorticoid administration protocol and the usefulness of immediate postoperative cortisol levels as a predictor of final eucortisolism. PATIENTS AND METHODS: Clinical and biochemical data from 40 patients aged 27 to 78 years (65% males) were prospectively collected. Exclusion criteria were previous use of GC, apoplexy and Cushing disease. Patients with pre-operative short synthetic ACTH test (SST) > 18 µg/dl or basal cortisol > 15 µg/dl did not receive GC. A morning serum cortisol (SC) threshold of 10 µg/dl in postoperative days one to three was used to decide a discharge without GC. Hypotension, dizziness or nausea, requirement of increased dose of corticosteroids, hospitalizations and emergency service visits were investigated, as well as surgical and endocrinological complications. Corticotropic status was evaluated three months after surgery. RESULTS: Macroadenomas were present in 87% of patients. Median hospital stay was 4 days and follow up lasted 9 months. No differences were found in gender, age or tumor size between patients who received or not GC (35 and 65% respectively). Eighty five percent of patients were discharged without GC and all of them had normal corticotropic function three months after surgery. A SC ≥ 15 µg/dl had 100% specificity to predict eucortisolism. CONCLUSIONS: Selective glucocorticoid administration is safe. A normal corticotropic function before surgery and in the immediate postoperative period are useful to identify patients who do not need GC.

Psychometric properties of Self-Compassion Scale Short Form (SCS-SF) in Spanish adolescents.

Background: Self-compassion, individual's ability to treat oneself kindly, is important for mental well-being. The Self-Compassion Scale (SCS) is the most used instrument to measure self-compassion, but the short form does not have validity evidence in adolescents. Methods: We examined the psychometric properties of the SCS-SF (12 items) in 955 Spanish adolescents (Mage = 13.95) using Confirmatory Factor Analysis (CFA) and reliability tests. The life satisfaction, family satisfaction, and reactive-proactive aggression were used for convergent validity. Results: Cronbach's alpha reliability value for the total scale was .723. CFA confirmed that the six-factor model showed good fit indices with three positive dimensions: self-kindness, common humanity, and mindfulness; and three negative components: self-judgment, isolation, and over-identification (χ2 = 114.730; CFI = .966; GFI = .98; RMSEA = .045). The bifactorial model also showed an adequate fit, although with weaker values than the six-factor (ꭓ2 = 247.108; CFI = .914; GFI = .95; RMSEA = .06). The unifactorial model showed an inadequate fit. Total SCS score correlated positively with family satisfaction (r = .43; p < .001) and life satisfaction (r = .48; p < .001) and negatively with reactive aggressiveness (r = -.27; p < .001) and with proactive aggressiveness (r = -.18; p < .001). Self-kindness, common humanity, and mindfulness were associated with higher family and life satisfaction (p < .001) Self-judgment, isolation, and over-identification were associated with lower family and life satisfaction (p < .001). Self-judgment and isolation positively correlated with both reactive and proactive aggression (p < .001), while mindfulness negatively correlated with both reactive and proactive aggression (p < .01). Conclusion: The SCS-SF is a valid and reliable instrument for assessing self-compassion in Spanish adolescents. Results suggest the six-factor model in its first validation in an adolescent population with convergent validity. The findings of this study corroborate the significance of self-compassion for the mental health of adolescents, particularly in relation to their family and life satisfaction.

Primary pituitary lymphoma in immunocompetent patient: diagnostic problems and prolonged follow-up.

Primary pituitary lymphoma in immunocompetent patients is a rare disease and has been described in less than 20 cases. Moreover, low-grade lymphomas constitute only 3% of all primary central nervous system lymphoma. The objective of this report is to report a low-grade primary pituitary lymphoma, diagnostic problems and to give more evidence about the evolution of this rare disease. A 49 y.o. woman was referred to our clinic with symptoms of hypopituitarism. A diagnostic work-up showed mild anemia, an erythrocyte sedimentation rate of 122 mm/h and a negative Elisa test for HIV. Panhypopituitarism was confirmed and the MRI showed a 20 mm sellar and suprasellar enhancing mass with a thickening of the pituitary stalk, chiasmal compression and bitemporal hemianopsia. She underwent transsphenoidal resection only 10 months later for non medical reasons. During this period she was clinically asymptomatic on hormonal replacement therapy. A new MRI showed regression of the suprasellar extension and invasion to the left cavernous sinus. A firm and infiltrative mass was found during transsphenoidal surgery, and only partial resection was performed. Biopsy showed a low-grade lymphoplasmacytic lymphoma. Staging was negative for other localizations. She was given chemotherapy and localized radiotherapy. Four years after surgery, the sellar MRI showed a 10 mm residual sellar mass with the persistence of a cavernous sinus invasion and she is considered to be in remission. The neurosurgeon and clinician should consider primary pituitary lymphoma as a potential cause of a sellar mass, especially in the presence of diabetes insipidus and an enhancing invasive mass. Neurosurgical biopsy is crucial for a correct diagnosis and prognosis could be better than classic CNS primary lymphomas.

Latissimus dorsi transfer for the treatment of massive tears of the rotator cuff.

The objective of this paper was to determine the outcome of the transfer of the latissimus dorsi tendon in patients with massive irreparable rotator cuff tears. Eighteen patients of mean age 54 years (range 37-72 years) with massive irreparable rotator cuff tears were studied. The mean follow-up was 28 months (range 12-58 months). The postoperative Constant score was higher by an average of 21.15 points compared to the preoperative score (P=0.002); 88.8% of patients reported significant pain relief and improved mobility, particularly on external rotation. Postoperative resting antero-posterior radiography in neutral rotation revealed a mean 3.2-mm depression of the humeral head, due to the tenodesis effect of tendon transfer, thus, increasing the deltoid lever arm. These clinical results suggest that latissimus dorsi transfer is a useful surgical technique for treating massive irreparable postero-superior tears of the rotator cuff in young and/or active patients, providing significant pain relief and improved shoulder strength.

Midnight salivary cortisol determination for assessing the outcome of transsphenoidal surgery in Cushing's disease.

CONTEXT: Midnight salivary cortisol (MSC) is now recognized as a reliable index for Cushing's syndrome diagnosis but has to be validated for the follow-up of treated patients. OBJECTIVE: Our objective was to evaluate MSC for assessing the outcome of transsphenoidal surgery (TSS) in patients with Cushing's disease (CD). DESIGN: We conducted a retrospective cohort study in a single center. PATIENTS AND METHODS: Sixty-eight patients treated by TSS between 1996 and 2006 and followed for at least 6 months with postoperative MSC were included. Mean follow-up (+/- sd) was 45 +/- 31 months. Morning plasma cortisol was determined 5 d after TSS, and MSC and urinary cortisol (UC) were determined 6-12 months after surgery. The remission group included hypocortisolic (morning plasma cortisol < 50 ng/ml and/or insufficient response to cosyntropin) and eucortisolic (midnight plasma cortisol < 75 ng/ml and normal UC) patients. Patients in the treatment failure group had high midnight plasma cortisol and UC concentrations. RESULTS: Fifty patients (74%) were in remission. Mean MSC was 0.7 +/- 0.4 ng/ml (range, 0.4-2.1 ng/ml) and 6.5 +/- 6.5 ng/ml (range, 2.1-27.2 ng/ml) for the remission and treatment failure groups, respectively (P = 0.001). A cutoff of 2 ng/ml for MSC gave a sensitivity of 100% and a specificity of 98% for treatment failure diagnosis, whereas UC less than 90 microg/d had a sensitivity of 71% and specificity of 98%. Postsurgical morning plasma cortisol less than or equal to 18 ng/ml had a sensitivity of 93% and specificity of 74%. CONCLUSIONS: MSC is a simple, robust marker of remission after TSS for CD.

Effects of bupropion, alone or coadministered with nicotine, on social behavior in mice.

Bupropion, administered alone or combined with nicotine, is presently used to treat nicotine dependence. Despite experimental evidence of the complex behavioral actions of this drug, there have been little data reported about its effects on social behavior. Our main aim was to investigate the effects of acute administration of bupropion, alone or plus nicotine, on social interaction in mice. OF1 group-housed male mice were confronted in a neutral cage with an anosmic opponent during a 10 minutes encounter. Time allocated to body care and digging was reduced by administration of bupropion (40 mg/kg) both when administered alone and with nicotine (1 and 0.5 mg/kg). The lowest dose of bupropion (10 mg/kg) also reduced digging when combined with 1 mg/kg of nicotine. Time spent on non-social exploration and exploration from a distance was significantly higher in mice treated with bupropion (40 mg/kg) alone or combined with nicotine (1 and 0.5 mg/kg). The lowest dose of bupropion (10 mg/kg) increased non-social exploration when combined with 0.5 mg/kg of nicotine and exploration from a distance when combined with 1 mg/kg of nicotine. Ethopharmacological assessment of the behavior of groups of mice treated with different combinations of the two drugs indicates that nicotine can potentiate some of the behavioral effects of low doses of bupropion. Results also indicate that bupropion, either alone or combined with nicotine, has no significant effects on social investigation, suggesting that this drug does not induce a clear anxiolytic profile in OF1 mice.

Long-term non-invasive ventilation therapies in children: A scoping review.

Long-term non-invasive ventilation (NIV) is a common modality of breathing support used for a range of sleep and respiratory disorders. The aim of this scoping review was to provide a summary of the literature relevant to long-term NIV use in children. We used systematic methodology to identify 11,581 studies with final inclusion of 289. We identified 76 terms referring to NIV; the most common term was NIV (22%). Study design characteristics were most often single center (84%), observational (63%), and retrospective (54%). NIV use was reported for 73 medical conditions with obstructive sleep apnea and spinal muscular atrophy as the most common conditions. Descriptive data, including NIV incidence (61%) and patient characteristics (51%), were most commonly reported. Outcomes from sleep studies were reported in 27% of studies followed by outcomes on reduction in respiratory morbidity in 19%. Adverse events and adherence were reported in 20% and 26% of articles respectively. Authors reported positive conclusions for 73% of articles. Long-term use of NIV has been documented in a large variety of pediatric patient groups with studies of lower methodological quality. While there are considerable data for the most common conditions, there are fewer data to support NIV use for many additional conditions.

Impact of preoperative ultrasonographic staging of the neck in papillary thyroid carcinoma.

OBJECTIVE: To determine the frequency of occult macroscopic metastasis detected by preoperative US evaluation of the neck in patients with PTC. Papillary thyroid carcinoma (PTC) is a malignancy with a high rate of lymph node metastasis. The findings of routine thyroid ultrasonography (US) and physical examination may underestimate metastatic disease. Thus, we propose that patients diagnosed as having PTC undergo preoperative US staging of the neck. DESIGN: This prospective study included 60 patients diagnosed as having PTC from January 1 through June 30, 2006. Patients had undergone previous thyroid US evaluation with no palpable adenopathy. Lymph nodes were deemed suspicious by US findings with a minor axis greater than 10 mm, a minor axis greater than 50% of the major axis, or hyperechogenicity with or without microcalcifications. Metastasis was confirmed by fine-needle aspiration biopsy or frozen section analysis. Patients with confirmed metastasis underwent a neck dissection. The location of adenopathy reported by US was correlated with the pathological report. RESULTS: The US evaluation identified 12 of 60 patients (20%) with adenopathy suggestive of metastasis. Metastasis was confirmed in 11 of 12 patients (92%). Metastasis was found in 1 of 48 patients who had a negative US finding. Overall, sensitivity, specificity, and positive and negative predictive values were 92%, 98%, 92%, and 98%, respectively. All neck levels with suspicious adenopathy detected by US evaluation, with 1 exception, were confirmed by pathological findings. Nine patients had additional neck levels involved with microscopic disease undetected by the US evaluation. CONCLUSIONS: In patients with PTC, preoperative US evaluation of the neck is effective in detecting nonpalpable metastasis. Therefore, routine preoperative neck US evaluation is recommended to optimize primary surgical planning.

Bupropion induces social anxiety in adolescent mice: Influence of housing conditions.

BACKGROUND: The antidepressant bupropion has received increasing attention as a pharmacological tool to treat addiction although little is known about its effects on social behaviour in adolescents. The present study aimed to evaluate if environmental housing conditions influence bupropion's actions on social behaviour of adolescent mice. METHODS: Mice were either group- or individually housed for 2-weeks and then randomly divided into 2 cohorts: half of the mice remained in the initial housing condition and the other half were changed to isolated conditions for further 2-weeks. The following groups were compared: isolated/isolated (ISO/ISO), isolated/group-housed (ISO/GR), group-housed/isolated (GR/ISO), and group-housed/group-housed (GR/GR). The effects of bupropion (40, 20, 10mg/kg) or saline on social interaction were assessed for each housing condition. Social encounters were evaluated using ethological analysis. RESULTS: Data showed significant effects of bupropion on grooming and digging. This drug diminished time mice allocated to these behavioural categories in all housing conditions. In ISO/GR and GR/ISO conditions, bupropion increased environmental exploration (non-social exploration and exploration from a distance), reduced social investigation and increased avoidance/flee and defence/submission behaviours. An augment of avoidance/flee during social interactions was observed in bupropion-treated mice in GR/GR housing condition. CONCLUSION: These results suggest that this drug exhibits anxiogenic-like properties in social encounters between adolescent mice, especially when a transition in housing conditions has been experienced during this period. Changes in housing conditions may be a useful model for evaluating the effects of bupropion on social behaviour and the role of environmental housing conditions.

Adolescent and adult mice display differential sensitivity to the effects of bupropion on the acquisition of a water maze task.

BACKGROUND: Adolescence is characterized by major neurobiological changes, and the effects of some psychoactive drugs seem to differ between adolescents and adults. Bupropion, an antidepressant that is also used to treat nicotine addiction, induces behavioral actions in both adolescent and adult rodents. However, the effects of this drug on spatial ability have not been compared in animals at different stages of their development. The present study was conducted to assess the effects of bupropion on spatial learning and memory in adolescent and adult mice. METHODS: Adolescent (post-natal day: PND35-36) and adult (PND >65) NMRI mice received bupropion (10, 20 and 40mg/kg) or saline during the acquisition (4 trials/day on 5 consecutive days) of a Morris water maze (MWM) task. Retention was evaluated with a probe trial performed after the acquisition phase. RESULTS: Data showed that age did not affect performance of the task. However, the factor Drug treatment reached statistical significance, with high doses of bupropion (40 and 20mg/kg) impairing acquisition of the MWM test in adolescents. The drug did not induce detrimental effects on the acquisition or retention of the task in adults. CONCLUSION: Bupropion impairs acquisition of the spatial task in adolescent but not in adult mice. It does not seem to alter retrieval of previously acquired spatial information in either adolescents or adults. Our findings suggest that, during the adolescent period, mice are more vulnerable to the actions of bupropion on spatial learning.

Sistematización del programa preventivo para menores en situación de conflictividad en el ámbito familiar en la comunidad de Andalucía: Programa NAYFA / Systematization of the preventive program for minors in conflict situations in the family environment in the community of Andalusia: NAYFA Program

En este artículo se describe el proceso de investigación-acción llevado a cabo para la redefinición y el diseño de un programa destinado a niños, niñas y adolescentes con dificultades y/o situaciones conflictivas en el ámbito familiar. El diseño del nuevo programa NAYFA se ha realizado siguiendo los estándares de calidad de los programas basados en la evidencia y mediante un proceso colaborativo entre responsables políticos, profesionales e investigadores. Se utilizó la técnica DAFO para identificar las principales fortalezas y debilidades de las actuaciones previas desarrolladas en diferentes provincias andaluzas. Los resultados pusieron de manifiesto una importante falta de sistematización que se ha tratado de solventar definiendo, mediante un proceso colaborativo y de acuerdo con los criterios de calidad más consensuados, los componentes clave del nuevo programa: fundamentación teórica y metodológica, destinatarios, objetivos, contenidos, condiciones de implementación y diseño de la evaluación. El alto grado de acuerdo de profesionales y responsables con las características propuestas puede contribuir a que la implementación del programa se lleve a cabo con fidelidad al diseño original y, con ello, favorecer su efectividad (AU)

This article describes the action-research process carried out to redefine and design a program for children and adolescents with difficulties and/or conflictive situations in the family. The design of the NAYFA program has been carried out following the quality standards of evidence-based programs and through a collaborative process between policymakers, professionals and researchers. The SWOT technique was used to identify the main strengths and weak-nesses of the previous actions carried out in different Andalucía provinces. The results revealed an important lack of systematization that an attempt has been made to solve by defining, through a collaborative process and in accordance with the most agreed quality criteria, the key components of the new program: theoretical and methodological founda-tions, recipients, objectives, contents, implementation conditions and evaluation design. The high degree of agreement of professionals and managers with the proposed characteristics can contribute to the implementation of the program being carried out with fidelity to the original design and, thus, favor its effectiveness.

Usefulness and Pitfalls in Sodium Intake Estimation: Comparison of Dietary Assessment and Urinary Excretion in Chilean Children and Adults.

BACKGROUND: High sodium intake has been associated with various noncommunicable disease like hypertension, cardiovascular disease, or stroke. To estimate accurately sodium intake is challenging in clinical practice. We investigate the usefulness and limitations of assessing sodium intake simultaneously by dietary assessment and urinary samples in both children and adults. METHODS: We used a cross-sectional study design inviting 298 Chilean subjects (74 children and 222 adults) aged between 9 and 66 years of both genders. Sodium intake by dietary assessment was obtained from Chilean food composition data, based on FAO tables. Sodium and creatinine excretion were measured in 24-hour urine samples, in all participants. RESULTS: Adequate urinary collection was obtained in 81% of children (59/74) and 61% of adults (135/222). The mean sodium intake by dietary assessment was similar to the sodium excretion in 24 hours (3,121±1,153mg/d vs. 3,114±1,353mg/24h, P = nonsignificant) in children but was significantly lower (3,208±1,284mg/d vs. 4,160±1,651mg/24h, P < 0.001) in adults. In both children and adults, sodium intake correlated with urinary sodium excretion (r = 0.456, P < 0.003 and r = 0.390, P < 0.001, respectively). Secondary analyses also suggested that the dietary assessment was more inaccurate in overweight adult subjects. CONCLUSIONS: Our results showed that average sodium intake was higher than recommended in both children and adults (WHO ≤2,000mg/d). The sodium intake estimated by dietary assessment correlated with urinary excretion in all subjects, but in obese adults was more inaccurate than in children. Future studies to validate the appropriate test to assess sodium intake by age and nutritional status are warranted.

Hormonal, Radiological, NP-59 Scintigraphy, and Pathological Correlations in Patients With Cushing's Syndrome Due to Primary Pigmented Nodular Adrenocortical Disease (PPNAD).

CONTEXT: Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of ACTH-independent Cushing's syndrome that may occur in an isolated form or as part of Carney complex. The diagnosis of this disease can be difficult preoperatively because computed tomography (CT) scan can be normal or suggest unilateral adrenal lesion, which can impede the correct diagnosis of bilateral adrenal disease. OBJECTIVE: The aim of our study was to describe the results of preoperative imaging (adrenal [6ß-(131)I]iodomethyl-19-norcholesterol] [NP-59] scintigraphy and standard adrenal CT scan) and their correlations with clinical, pathological, and genetics investigations in patients with PPNAD. PATIENTS AND METHODS: Seventeen patients with ACTH-independent syndrome due to PPNAD were investigated with a standard adrenal CT scan and NP-59 scintigraphy. Hormonal, pathological, and genetics data were analyzed. RESULTS: Four males and 13 females (median age, 27 y) were included. PPNAD was isolated in 11 patients (with PRKAR1A mutation, n = 7; and without PRKAR1A mutation, n = 4) and was associated with extra-adrenal manifestations of Carney complex in six patients (with PRKAR1A mutation, n = 4; and without PRKAR1A mutation, n = 2). Standard adrenal CT scan revealed micronodules in 11 patients, macronodules in three patients, and was normal in three patients. All patients demonstrated bilateral adrenal radiocholesterol uptake. Adrenal uptake was asymmetrical in 10 of 17 patients (59%). Asymmetrical uptake correlated with the presence of macronodules at pathological analysis (P = .03). CONCLUSION: Standard adrenal CT scan most often reveals micronodules but there is no specific CT imaging. NP-59 scintigraphy always shows a bilateral adrenal uptake confirming the bilateral nature of the disease, but asymmetrical scintigraphic uptake can be observed in patients with macronodules.

Long-term non-invasive ventilation therapies in children: a scoping review protocol.

INTRODUCTION: Non-invasive ventilation (NIV) in children has become an increasingly common modality of breathing support where pressure support is delivered through a mask interface or less commonly through other non-invasive interfaces. At this time, NIV is considered a first-line option for ventilatory support of chronic respiratory insufficiency associated with a range of respiratory and sleep disorders. Previous reviews on the effectiveness, complications and adherence to NIV treatment have lacked systematic methods. The purpose of this scoping review is to provide an overview of the evidence for the use of long-term NIV in children. METHODS AND ANALYSIS: We will use previously established scoping methodology. Ten electronic databases will be searched to identify studies in children using NIV for longer than 3 months outside an intensive care setting. Grey literature search will include conference proceedings, thesis and dissertations, unpublished trials, reports from regulatory agencies and manufacturers. Two reviewers will independently screen titles and abstracts for inclusion, followed by full-text screening of potentially relevant articles to determine final inclusion. Data synthesis will be performed at three levels: (1) an analysis of the number, publication type, publication year, and country of publication of the studies; (2) a summary of the study designs, outcomes measures used; (3) a thematic analysis of included studies by subgroups. ETHICS AND DISSEMINATION: This study will provide a wide and rigorous overview of the evidence on the use of long-term NIV in children and provide critical information for healthcare professionals and policymakers to better care for this group of children. We will disseminate our findings through conference proceedings and publications, and evaluate the results for further systematic reviews and meta-analyses.
