Authors: Krueger D. R. , Guenther K-P. , Deml M. C. , Perka C.
Published: April 2020

Aims

We evaluated a large database with mechanical failure of a single uncemented modular femoral component, used in revision hip arthroplasty, as the end point and compared them to a control group treated with the same implant. Patient- and implant-specific risk factors for implant failure were analyzed.

Methods

All cases of a fractured uncemented modular revision femoral component from one manufacturer until April 2017 were identified and the total number of implants sold until April 2017 was used to calculate the fracture rate. The manufacturer provided data on patient demographics, time to failure, and implant details for all notified fractured devices. Patient- and implant-specific risk factors were evaluated using a logistic regression model with multiple imputations and compared to data from a previously published reference group, where no fractures had been observed. The results of a retrieval analysis of the fractured implants, performed by the manufacturer, were available for evaluation.

Results

There were 113 recorded cases with fracture at the modular junction, resulting in a calculated fracture rate of 0.30% (113/37,600). The fracture rate of the implant without signs of improper use was 0.11% (41/37,600). In 79% (89/113) of cases with a failed implant, either a lateralized (high offset) neck segment, an extralong head, or the combination of both were used. Logistic regression analysis revealed male sex, high body mass index (BMI), straight component design, and small neck segments were significant risk factors for failure. Investigation of the implants (76/113) showed at least one sign of improper use in 72 cases.

Conclusion

Implant failure at the modular junction is associated with patient- and implant-specific risk factors as well as technical errors during implantation. Whenever possible, the use of short and lateralized neck segments should be avoided with this revision system. Implantation instructions and contraindications need to be adhered to and respected.

Contribution of Transverse Reinforcement Configuration on Concrete Shear Capacity of RC Column
Authors: Saidi Taufiq , Putra Rudiansyah , Amalia Zahra , Munawir Munawir
Published: April 2020

Proper design of transverse reinforcement in the RC column is needed to maintain its ability to deform under axial and shear load safely. Even though mandatory building codes for transverse support of the RC column exist, shear failure was still found in the last high earthquake in Pidie, Aceh, in 2016. Therefore, as an attempt to improve RC column strength and elasticity, the effect of transverse reinforcement configuration was evaluated experimentally to a column subjected to an axial and shear load. The experiment was conducted by using four-column specimens with a cross-section 200 x 200 mm. Four types of transverse reinforcement configurations were applied in each column. The test was carried out by loading an axial load always and shear load gradually until its failure. The test results show that the configuration of transverse reinforcement has a significant effect of maintaining column stiffness, which was subjected to compressive axial load and shear load. Furthermore, the arrangement of transverse reinforcement influences the compressive strength significantly and enhance the concrete shear capacity of a column due to its confinement effect.
El Catálogo de la mujer de Florida Universitària, una herramienta para fomentar la igualdad.
Authors: Verdugo Martí Vicenta , Moraga Barrero Patricia
Published: April 2020

This paper describes the creation of Florida Universitaria CRAI’s Catálogo de la mujer. Florida is an educational cooperative set up in the region of Valencia in the 1970s, a time when many projects were launched in an attempt to change and modernize approaches to teaching. Since its inception, the values that have underpinned its work have been a management style based on democratic practices, secularism, the promotion of the Valencian language and coeducation, and the application of the Mondragón business model. These values have also shaped the creation of the bibliographical archives belonging to the CRAI-Bibilioteca and the rest of the cooperative’s libraries. Since the first professional training programmes in 1977-1978, the cooperative has adapted the courses on offer to the needs of its public (and also in line with its budget). Florida Universitària came into being in the early 1990s, as an associated centre attached to the Valencia’s two main universities (the University of Valencia and the Polytechnic University). Finally, the language centre was founded in 1994. La Florida is based in Catarroja, a town in the Horta Sud of Valencia, where secondary school studies, language teaching and university courses are taught at three different sites. These centres were created at different stages of the cooperative’s history, building on the original secondary school and expanding to cover the teaching needs of a group of villages located some way away from the city, and responding to the rising demands of the area’s industrial sector.

In this paper, the self-absorption of InGaN quantum wells at high photon density is studied based on a rectangular ridge structure. The ridge structure was fabricated based on a standard GaN-based blue LED wafer grown on (0001) patterned sapphire substrate. The high-density photons were obtained by a high-power femtosecond laser with high excitation of

at room temperature. Based on the analysis of the photoluminescence intensities of the InGaN quantum wells, we found that the absorption coefficient of the InGaN quantum wells varies with the background photon density. The results revealed that the final absorption coefficient of the InGaN quantum well decreases with the increase of photon density, which can be 48.7% lower than its normal value under our experimental conditions.

Atendimento psicológico a populações de baixa renda. Considerações acerca do interjogo cultura e subjetividade
Authors: Vilhena Junia de , Novaes Joana de Vilhena , Bittencourt Maria Inês Garcia de Freitas
Published: April 2020

A clínica psicanalítica com populações de baixa-renda constitui-se como um campo novo de trabalho e de pesquisa. A Psicanálise, pelo menos no Brasil, é, freqüentemente, acusada de ser ineficaz no tocante a este tipo de atendimento, sendo um dos seus mais instigantes desafios sua inserção na realidade brasileira, marcada por imensa apartação social. O presente trabalho tem como objetivo discutir o atendimento psicanalítico a populações de baixa renda, tomando como eixo de reflexão a indissociabilidade entre o singular do sujeito e o universal da cultura, aqui tematizada como um dos fundamentos de nosso dispositivo clínico na busca da compreensão do sujeito que sofre. Discutimos, ainda, como a psicanálise nos dá as ferramentas apropriadas, sobretudo, quando estabelecemos um diálogo com outros campos do saber.

Published: April 2020

Falsas Memórias (FM) são baseadas em erros da memória e ocorrem quando as pessoas lembram‑se de situações que não aconteceram, eventos não presenciados, ou então, as lembranças dos fatos ocorridos são lembrados de maneira distorcida. O objetivo desse artigo é apresentar dados de tempo de reação sobre falsas memórias com a adaptação do paradigma DRM (Deese‑Roediger‑McDermott) para o português brasileiro. O experimento foi aplicado em 12 participantes. Foram manipulados os fatores conjuntos de palavras memorizadas (CPM) compostos por 3, 5 ou 7 itens e o tipo de prova (alvo, distratorcrítico e distrator não relacionado). Os resultados apontam uma tendência de aumento do tempo de reação em função do conjunto de palavras memorizadas e confirmam a importância do tempo de reação como uma medida para se estudar as falsas memórias em situações de curto prazo.
Adaptação e validação da Eustress Scale para professores portugueses
Authors: Fonseca Susana , Jordão Filomena
Published: April 2020

O stress dos professores tem sido largamente estudado, mas, o seu enfoque tem sido predominantemente direcionado para a sua vertente disfuncional. Contudo, diversos estudos indicam que o stress pode apresentar‑‑se como uma resposta psicológica positiva a um stressor, designando‑‑se de eustress (Campbell‑‑Quick, Cooper, Nelson, & Gavin, 2003; Simmons & Nelson, 2001; Simmons, Nelson, & Quick, 2003).Este estudo foi realizado numa amostra de 496 professores e teve como principal objetivo adaptar e validar a eustress scale, desenvolvida por O’Sullivan (2011), para professores portugueses.Os resultados evidenciam que a escala possui qualidades psicométricas adequadas, com um valor elevado de consistência interna (α = .93), semelhante ao encontrado anteriormente com uma amostra independente (Fonseca & Jordão, 2011). O fator resultante da análise fatorial exploratória explica 78,87% da variância total.Mais estudos devem ser realizados para validar a escala de eustress, nos professores e para a população portuguesa em geral, analisando, nomeadamente, a estabilidade da escala.

Published: April 2020

According to recent models of recovery in psychosis, the patients’ perspectives about their own difficulties, symptoms and goals (health-related and in other areas) are of major importance in intervention. Self-report measures have been increasingly studied and several authors have pointed out their validity, reliability and clinical utility in people with psychotic-disorders. The present study sought to review and critically analyse the available self-report instruments for assessing delusions. Four instruments met the inclusion criteria: Characteristics of Delusions Rating Scale; Beliefs Rating Scale; Peters Delusions Inventory; and Conviction of Delusional Beliefs Scale. All scales assess delusions in a multidimensional perspective and present adequate psychometric properties, although with high variability within studies. Refining the psychometric studies of the existing instruments (mainly confirmatory factor analysis, reliability and diagnostic accuracy analyses) and developing new instruments focused on coping are future areas of research interest.

Published: April 2020

This paper is based on a study that was carried out to assess the implementation of cabotage act in Nigeria from the perspectives of the seafarers and shipowners who are considered as the major stakeholders in maritime sector and are directly affected by this act. The objectives of this study were to evaluate cabotage operations and to ascertain the effect of cabotage act implementation on Nigerian seafarers onboard cabotage vessels. Primary data was used through a design of questionnaire and interview. Fifty (54) copies of questionnaires were retrieved out of 60 copies that were administered. The method of data analysis was descriptive using statistical mean and percentages with the aid of Statistical Package for Social Sciences (SPSS) version 23. The data collected were measured in 5-point Likert scale with a hypothesized mean of 3.00. The findings of the study revealed that despite some successes recorded in the aspect of increase in the number of cabotage vessels operating on Nigeria waters and increase in the number of Nigerian seafarers employed onboard these cabotage vessels , there are still some challenges in respect to the implementation of this act such as, low capacity of Nigerian ship building industry to meet the demand of cabotage trade market, inability of shipowners to access fund to enhance their operations, lack of adequate attention to the condition of service and welfare of Nigerian seafarers onboard cabotage vessels. This study recommends investment in Nigerian shipbuilding industry in order to meet the demand of cabotage trade and also seeks enforcement of the ratified Maritime Labour Convention by Nigeria Maritime Administration and Safety Agency (NIMASA) in order to ensure better working and living conditions for Nigeria Seafarers.
Impact of the cargo customs complex efficiency on the supply chain reliability
Authors: Luzhanska Nataliia
Published: April 2020

Creating supply chain involving the customs infrastructure facilities is an urgent topic when shipping cargo internationally. The most in demand are cargo customs complexes, which have in their structure customs storerooms, warehouses of temporary storage, perform freight-forwarding, and customs-brokerage and other functions that are necessary to perform foreign economic activity. Also there are subdivisions of customs authorities on their territory. This type of business activity provides the business entities with the comprehensive service and enables them to reduce the time spent moving to each of the necessary control services or logistics facilities when moving cargoes in different customs regimes. Therefore, it is proposed to apply the concept of logistics chain reliability with a freight customs complex as its element. The latter will take into account business entities` financial and time expenditures with non-productive timing at the different transition stages of material flow, and will enable to optimize information flows. The paper considers the procedure of placing imported goods in a temporary storage warehouse. It is proposed the regulation methodology for individual service stages provided by a freight customs complex. The generalized algorithm for constructing a reliability model of a freight customs complex`s operation is offered allowing to determine the reliability level of each individual element in a logistics chain.
Medidores de baixo custo para a quantificação de fluxo e coleta de amostras de água na interface leito/sedimentos em rios de montanha
Authors: Carias Victor Alves , Vilanova Mateus Ricardo Nogueira
Published: April 2020

O estudo do fluxo hiporreico ganhou atenção nas últimas décadas, devido ao reconhecimento dos diversos processos físicos, geoquímicos e biológicos que ocorrem em sua interface. Estes influenciam, direta e indiretamente, os ecossistemas e a disponibilidade de recursos hídricos. A importância e a complexidade da zona hiporreica é aumentada em rios de montanha, localizados em regiões de alta relevância conservacionista e grande variabilidade hidrometeorológica. Apesar disso, a utilização de medidores de fluxo (seepage meters) tradicionais pode ser inviável nesse tipo de rio, devido às suas características físicas (composição granulométrico e geometria do leito) e pela dificuldade de acesso a certas áreas montanhosas. Diante do exposto, este trabalho reporta o desenvolvimento e a avaliação (laboratorial e in loco) de dois tipos de medidores de fluxo de baixo custo, construídos com tubos de PVC e baldes industriais. Uma bancada experimental com controle/medição de vazão, simulando um leito fluvial, foi desenvolvida para os ensaios, que tiveram seus resultados avaliados a partir do cálculo da da incerteza-padrão Tipo “A”. Os testes laboratoriais realizados permitiram concluir que o medidor construído com balde industrial (M2) pode ser utilizado em medições reais, enquanto o medidor feito com tubo de PVC (M1) não apresentou bom desempenho. Durante os testes, o M2 apresentou um desvio de aproximadamente 12% em relação à vazão de referência da bancada, com uma incerteza padrão de 0,40 L.m-2.
Airport pavement roughness evaluation based on cockpit and center of gravity vertical accelerations
Authors: Durán Jorge Braulio Cossío , Fernandes Júnior José Leomar
Published: April 2020

Pavimentos irregulares são geralmente responsáveis por acelerações verticais (VA) que afetam as aeronaves, aumentam a distância de parada e dificultam a leitura dos instrumentos de navegação na cabine dos pilotos. O International Roughness Index (IRI) e o Boeing Bump Index (BBI) são utilizados atualmente para quantificar a irregularidade longitudinal dos pavimentos aeroportuários e identificar seções que demandam atividades de manutenção e reabilitação (M&R). Contudo, tais índices baseiam-se apenas nas respostas dinâmicas de um automóvel a 80 km/h às irregularidades longitudinais dos pavimentos rodoviários, bem como nas características físicas das irregularidades (comprimento e altura), respectivamente, ignorando o efeito das VA nas aeronaves. Ainda, limites críticos atuais, sugeridos por Sayers & Karamihas e ANAC para IRI (2,0 e 2,5 m/km, respectivamente) e pela FAA para BBI (1,0) podem subestimar a condição real do pavimento. Este artigo avalia o efeito da irregularidade longitudinal nas acelerações na cabine dos pilotos (VACP) e no centro de gravidade (VACG). O software ProFAA permitiu calcular os índices e simular as VA em 4 aeronaves representativas atravessando 20 pistas de pouso e decolagem em 10 velocidades de taxiamento variando de 37 a 370 km/h. Comparações estatísticas e análises de regressão foram realizadas. Principais resultados mostram que VACP é 50% maior do que VACG e que ultrapassa o limite critico de 0,40 g quando o IRI e BBI estão acima de 3,7 m/km e 0,20, respectivamente. Um estudo de caso é também apresentado para comparar esses limites e sugere que a tomada de decisão baseada em IRI e VA pode trazer diferenças significativas na quantidade de atividades de M&R.
Estudo da separação entre pistas de pouso e decolagem e de taxiamento em aeródromos brasileiros – aplicação ao Aeroporto Internacional de Fortaleza

Published: April 2020

Inadequações relativas ao projeto geométrico podem ser consideradas comuns em aeroportos pelo mundo. No Brasil, alguns aeroportos apresentam inconformidades de separação entre eixos de pistas de pouso e decolagem e de taxiamento paralelas que são inferiores aos requisitos exigidos pela Agência Nacional de Aviação Civil. Este trabalho objetiva avaliar o impacto de tal situação no risco de colisões associado a operações simultâneas de aeronaves em condições de operação por instrumentos. Para tanto, foi utilizado um método de análise de risco proposto pelo Airport Cooperative Research Program do Transportation Research Board com aeronaves de três categorias distintas que operam no Aeroporto Internacional de Fortaleza. Percebeu-se que há probabilidades reduzidas de acidentes acontecerem nestas condições, sendo o método apresentado um meio relevante para a análise quantitativa dos riscos operacionais em tais situações de inconformidade, podendo esta abordagem ser aplicada em casos similares.

Published: April 2020

O presente trabalho de pesquisa utiliza o novo programa de dimensionamento de pavimentos flexíveis no Brasil (MeDiNa), para o cálculo de reforço do pavimento do anel viário da Universidade Federal de Juiz de Fora visando o restabelecimento de propriedades funcionais. Esse pavimento é avaliado funcionalmente através de Levantamento Visual Contínuo Informatizado (LVCI) e ensaio de irregularidade longitudinal, e estruturalmente por meio de levantamento de deflexões realizado por equipamento FWD e abertura de poço de sondagem. Com os dados coletados na avaliação estrutural, é realizada a segmentação homogênea do trecho e uma retroanálise de dados para obtenção de parâmetros necessários ao referido cálculo. Após o devido dimensionamento chegou-se à conclusão de que a melhor solução de reforço é o recapeamento de toda sua extensão com a mistura asfáltica de projeto em espessura única de 5,0 cm, observando a aplicação de uma camada antirreflexão de trincas em alguns trechos.

PENINGKATAN EFISIENSI ENERGI KIPAS SIRKULASI UDARA DI PANEL LISTRIK MELALUI PENGATURAN KECEPATAN
Authors: Tadeus Dista Yoel , Mangkusasmito Fakhruddin
Published: April 2020

Internal temperature of electric panel practically depend on the amount of power dissipation generated by the panel components and the outside temperature. If this equilibrium is not maintained then the internal temperature can increase too high beyond the working temperature limit for components so as to shorten the life of panel components. Generally, there are two fans installed to circulate the air inside the panel that operates at  fixed speed. In order to improve fan energy efficiency, it is necessary to add a control system that can adjust the fan speed based on actual panel internal temperature. Efforts to increase energy efficiency are realized using cheap hardware and easily available on the market, the ATMEGA 8535 microcontroller and LM 35 temperature sensor. The fan speed is normalized in percent units and expressed virtually using the Pulse Width Modulation (PWM) signal value calculated by the proportional control algorithm inside the controller. The experimental results show that the PWM value can vary with actual panel internal temperature. Using the time constant temperature asumption k1 = 0.2, k2 = 0.4, k3 = 0.2, k4 = 0.2 and experimental data, it was shown by calculations that there was an increase in energy efficiency by 40.8%.

The identification system is a procedure to obtain a model of a system, then of the model will be validated to see the accuracy of the model is obtained, compared to the input-output results obtained from the experiments. In the identification system itself known two methods, the method of "non-parametric" and "parametric". On the other hand, DC motor is a type of motor that uses direct electric current to produce rotational mechanical energy and is widely used in various applications. In this study, input and output data acquisition will be performed on the Feedback brand DC motor, and the data will be processed so that the system model is obtained by the black box method. The data will then be processed with the help of MATLAB software. The input signal used in this experiment is Pseudorandom binary sequence (PRBS), which is used because it has a wide frequency range. The signal is generated by an arduino uno microcontroller. From the test results it was found that the validation of the non parametric system model with the correlation analysis method has a fitness value of = 83.19%, while the validation of the parametric system model with the least square ARX method has a fitness value of = 80.59%.

Den Ausgangspunkt für den Artikel bildet die Aussage von Kathrin Röggla, derzufolge „Was in Österreich – nicht nur in der Literatur – Tradition hat, ist Ironie“. Den Gegenstand der Untersuchung bilden Ironie-Konzepte in drei Romanen der österreichischen Autorinnen der Gegenwart Olga Flor, Teresa Präauer, Cordula Simon. Die Fragestellung ist auf die spezifisch „österreichische“ Ironie ausgerichtet, die, so die These, eine besondere Form der Auseinandersetzung mit aktuellen sozialen und politischen Themenkomplexen darstellt.
Zwischen Stigmatisierung und Normalität. Positionen interkultureller Autor_innen im literarischen Feld (Kim, Flašar, Rabinovici, Stavarič)
Authors: Pokrywka Rafał
Published: April 2020

Aus dem Standpunkt der soziologischen Feldtheorie sind Mehrsprachigkeit, interkultureller Hintergrund und Fremdheit soziale und kulturelle Kapitalsorten, die auch Teil des symbolischenKapitals werden können. Im Beitrag werden vier österreichische Autor_innen besprochen, die im Hinblick auf den attestierten/deklarierten interkulturellen Charakter ihres Schaffens unterschiedliche Positionen im literarischen Feld einnehmen: Anna Kim, Milena Michiko Flašar, Doron Rabinovici und Michael Stavarič. Im Ausblick wird der Frage nachgegangen, ob ihre Stigmatisierung als ‚Fremde’ auch feldinterne Profite bringen kann und ob die erwartete Normalisierung der interkulturellen Literatur in jeder Hinsicht erwünscht ist.
„entwurzelt & umgetopft.“ Das literarische Potential der Mehrsprachigkeit bei Julya Rabinowich
Authors: Schulte Sanna
Published: April 2020

Die Autorin und Dolmetscherin Julya Rabinowich bezeichnet sich selbst als „Janus in Babylon“ und charakterisiert ihre Mehrsprachigkeit nicht nur als vermittelnde Kompetenz, sondern auch als wechselnde Identität: „Spaltköpfig wird man. Doppelzüngig. Mehrgesichtig.“ (Rabinowich 2009: 58) Das Spiel mit den eigenen Identitäten, mit Lüge und Wahrheit, mit Vergangenheit und Zukunft scheint die beste Voraussetzung zum Schreiben. Welches poetische Potential in der Exophonie liegen kann, untersucht dieser Beitrag anhand von Julya Rabinowichs Roman Spaltkopf, der als Entwurf eines mehrdimensionalen Identitätskonflikts gelesen wird. Im Vergleich mit mehrsprachigen Perspektiven und exophonen Schreibweisen von Yoko Tawada, Herta Müller, Dragica Rajčić, Emine Sevgi Özdamar, Saša Stanišić und Semier Insayif werden besonders die Kippeffekte zwischen metaphorischen und buchstäblichen Lesarten fokussiert.
Analysis of Production Technology of Wood Briquettes, Including Costs and Distribution
Authors: Jasiczek Filip , Kwaśniewski Dariusz
Published: April 2020

The paper analyzes the costs of production of wood sawdust briquettes, manufactured by the company Brykiet-Pol2, based in Goleszów in southern Poland. In addition, production technology, raw material supply and distribution of the finished product were analyzed. The costs of producing one ton of briquettes for the four assessed variants ranged from PLN 364.8 (option D) to PLN 648.7 (option A). The cost structure was dominated by the purchase of raw material and depreciation of the technological line. The most economically advantageous production variant was option C, currently implemented in the company (production costs: PLN 458.7·t−1), and the proposed option D, using two briquetting presses. The latter option increased production efficiency and reduced unit costs of briquette production in a three-shift system around the clock.

Authors: Sporysz Maciej , Szczuka Maria , Tabor Sylwester , Molenda Krzysztof , Kuboń Maciej
Published: April 2020

A modern model of agriculture is based on three orders - organic, social and economic. An attempt was made in this paper to apply cluster analysis for assessment of economic and organic sustainability of organic farms. Factors that statistically influenced a decision on which farms should be recognised as sustainable were indicated. Analyses allow the following conclusion: 1) in organic farming, animal production including cattle breeding and rearing must be based on a high acreage of permanent grasslands; 2) neither the performed production processes nor the level of their automation rate or the level of organic balance do not decide on the production effectiveness, but factors of the surrounding including social factors.

Authors: Szmajda Grażyna , Nowakowski Tomasz
Published: April 2020

Field tests on the quality of shaking off redcurrant fruit Rosetta cultivar with a half-row trailer harvester “Marek” produced by Dom-Wid were carried out. The tests were performed at two average working speeds ῡ1 = 0.47 m·s−1; ῡ2 = 0.60 m·s−1 and two rotational speeds of a tractor n1 = 1500 rpm; n2 = 1900 rpm. The length and diameter of shoots of redcurrant, length of a bunch, number of fruits in a bunch and mass of fruit were measured. Weather conditions were presented: rain fall, air temperature and moisture. Analysis of results showed that the working speed and the rotational speed has a significant impact on the quality and amount of the yield. At the highest rotations, the harvesting quality of fruit by a harvester was the worst and was 77.15%.
Foreign Policy Attitudes of the Black Talented Tenth
Authors: Leach Antwain , Hussain Sajid
Published: April 2020

Do Talented Tenth and non–Talented Tenth Blacks support moral and socially conscious US foreign policies to the same degree? Utilizing a 2010 national sample from the Chicago Council on Global Affairs, we find statistical evidence that members of the Talented Tenth are more likely than other Blacks to support America’s role to combat global hunger and to provide economic aid to assist needy countries in developing their economies. An examination of the foreign policy attitudes of the Black Talented Tenth is an important undertaking because it provides insight into what our expectations should be for rising African Americans as more of them enter into its ranks. Should we expect the next generation of African Americans to be more conscientious as they increasingly assume the mantles of leadership and responsibility? The results in this article lay bare the enormous work the present generation of Black educators must undertake to ensure the next generation are ready to do so. By observing the internationalist attitudes of the present Talented Tenth, especially as those attitudes relate to creating a more just, equitable, and harmonious world, it is possible to find ways to critically engage and help the next generation to provide the type of leadership necessary to make a positive difference.

Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of ACTH-independent Cushing syndrome (CS). This condition is characterized by glucocorticoid and/or mineralocorticoid excess, and is commonly regulated by aberrant G-protein coupled receptor expression may be subclinical, allowing the disease to progress for years undetected. Inhibin A is a glycoprotein hormone and tumor marker produced by certain endocrine glands including the adrenal cortex, which has not been previously investigated as a potential tumor marker for PBMAH. In the present report, serum inhibin A levels were evaluated in three patients with PBMAH before and after adrenalectomy. In all cases, serum inhibin A was elevated preoperatively and subsequently fell within the normal range after adrenalectomy. Additionally, adrenal tissues stained positive for inhibin A. We conclude that serum inhibin A levels may be a potential tumor marker for PBMAH.

Learning points:

PBMAH is a rare cause of CS.

PBMAH may have an insidious presentation, allowing the disease to progress for years prior to diagnosis.

Inhibin A is a heterodimeric glycoprotein hormone expressed in the gonads and adrenal cortex.

Inhibin A serum concentrations are elevated in some patients with PBMAH, suggesting the potential use of this hormone as a tumor marker.

Further exploration of serum inhibin A concentration, as it relates to PBMAH disease progression, is warranted to determine if this hormone could serve as an early detection marker and/or predictor of successful surgical treatment.

Published: April 2020

Context

Association of central diabetes insipidus (CDI) and pituitary stalk thickening (PST) may have several etiologies (including malignancies) and differential diagnosis remains often difficult.

Objective

The purpose of this study was to identify which clinical, biochemical or radiological features could help clinicians to make an etiological diagnosis, especially distinguishing neoplastic from non-neoplastic pituitary stalk lesions.

Design and methods

We retrospectively analyzed clinical, biochemical, radiological and histological data of 38 adult patients diagnosed with CDI and PST of proven etiology.

Results

Of the 38 pituitary stalk lesions included, 11 (29%) were neoplastic. A histopathological diagnosis was obtained in 22/38 (58%) patients. The three most frequently observed etiologies of PST were neuroinfundibulitis (34%), germinoma (21%) and histiocytosis (18%). Pituitary stalk thickness was larger for neoplastic lesions, particularly germinomas. Male gender and a very young age were statistically associated with a risk of germinoma. At least one anterior pituitary deficit was observed in nearly 60% of patients. Patients with neoplastic PST were more affected by multiple anterior pituitary dysfunction than patients with benign PST. A high serum prolactin level was individually the best predictor of a neoplastic origin (90% sensitivity and 60% specificity for a serum prolactin level 1.27-fold above the normal upper limit (ULN)).

Conclusion

We confirm a relatively high risk of malignancy in adult patients presenting with the association of CDI and PST. Young age, male gender, a very large thickening of the stalk, multiple anterior pituitary deficits and prolactin above 1.3× ULN increase the likelihood of a neoplastic origin.
