Consecuencias sociolaborales del confinamiento por la COVID-19 en pacientes con esclerosis múltiple en dos poblaciones muy diferentes / Socio-labor consequences of confinement by COVID-19 in patients with multiple sclerosis in two very different populations

El confinamiento debido a la pandemia de la COVID-19, realizado a nivel mundial, ha tenido consecuencias casi siempre negativas en los pacientes con esclerosis múltiple (EM). OBJETIVO: Hemos comparado el efecto sociolaboral que el confinamiento ha podido tener en pacientes con EM de dos poblaciones tan diferentes como son España y China. MÉTODO: Se elaboraron unos cuestionarios a lo que respondieron un grupo de pacientes de EM que son revisados en la unidad de EM del hospital Vithas (Fundación DINAC) en Sevilla, y pacientes con EM atendidos en varias provincias de China durante el mes de abril de 2020, con el objetivo de analizar las diferencias y similitudes del efecto sociolaboral entre ambas poblaciones. Para llevar a cabo este análisis se creó una base de datos que se analizó posteriormente. RESULTADOS: La población china tiene una mayor proporción de pacientes más jóvenes y no hay diferencia respecto al género. La mayoría de las variables estudiadas se comportaron de igual forma en los pacientes con EM tanto españoles como chinos. Los pacientes españoles presentaron menos impacto (30,7%) en su situación socioeconómica que los chinos (44%), p < 0,05. No hubo diferencias importantes en el resto de las variables entre las dos poblaciones. Las redes sociales fueron muy utilizadas en la mayoría de los enfermos de ambas poblaciones. CONCLUSIONES: Los pacientes con EM padecen de forma muy similar las consecuencias de la pandemia en su situación sociolaboral y utilizan de forma parecida las redes sociales y el apoyo de la familia. Los pacientes españoles disfrutan de más estabilidad económica, probablemente gracias al apoyo social que reciben

The confinement due to the global COVID-19 pandemic has almost had negative consequences in patients with multiple sclerosis (MS). OBJECTIVE: We wanted to compare the socio-labor effect of confinement in two populations as different as Spain and China, in patients with MS. METHOD: Questionnaires were applied to a group of MS patients who have been reviewed in the MS unit of the Vithas hospital (DINAC Foundation) in Seville, and MS patients attended in various provinces of China during the month of April 2020, with the aim of analyzing the differences and similarities of the socio-labor effect between both populations. To carry out this analysis, a database was created and subsequently analyzed. RESULTS: The Chinese population has a higher proportion of younger patients and there is no difference regarding gender. Most of the variables studied behaved the same way in both Spanish and Chinese MS patients. Spanish patients had less impact (30.7%) on their socio-economic situation than Chinese (44%), P < .05. There were no important differences in the rest of the variables between the two populations. Social networks were widely used in the majority of patients in both populations. CONCLUSIONS: MS patients suffer in a very similar way from the consequences of the pandemic on their socio-labor situation and similarly use social networks and family support. Spanish patients seem to have more economic stability, which may be due to social economic support

Social and professional consequences of COVID-19 lockdown in patients with multiple sclerosis from two very different populations. / Consecuencias sociolaborales del confinamiento por la COVID-19 en pacientes con esclerosis múltiple en dos poblaciones muy diferentes.

The global lockdown measures implemented due to the COVID-19 pandemic have nearly always had negative consequences for patients with multiple sclerosis (MS). OBJECTIVE: We compared the social and professional effects of confinement on patients with MS in 2 very different populations, from Spain and China. METHODS: Questionnaires were administered to a group of patients with MS who consulted at the MS unit of Vithas hospital (DINAC Foundation) in Seville, and patients with MS attended in several provinces of China in April 2020, with the aim of analysing the differences and similarities between populations in the social and professional effects of confinement. To this end, a database was created and subsequently analysed. RESULTS: The Chinese population includes a higher proportion of younger patients and no differences were identified regarding sex. Most of the variables studied behaved in the same way in both patient populations. Spanish patients presented a lesser impact (30.7%) on their socio-economic situation than Chinese patients (44%) (P < .05). There were no significant differences between populations in the remaining variables. Social networks were widely used in the majority of patients from both populations. CONCLUSIONS: The social and professional consequences of the pandemic were very similar in both groups; the use of social networks and family support was also similar. Spanish patients seem to present greater economic stability, perhaps due to the social support they receive.

Megestrol acetate-induced adrenal insufficiency

Megestrol acetate is a synthetic progestin that has been used since the 1970s for the treatment of advanced cancer and subsequently to treat anorexia, cachexia and weight loss in AIDS patients. It has been shown that high doses or prolonged treatment with this drug may cause Cushing's syndrome, new-onset diabetes and suppression of plasma ACTH and cortisol levels. Megestrol acetate may cause suppression of the pituitary-adrenal axis due to the affinity of this compound for the glucocorticoid receptor. Recognising the glucocorticoid-like activity of megestrol and its effects at the axis level is important for the diagnosis of sub-clinical adrenal insufficiency. We present the case of a 74-year-old woman with infiltrating ductal breast carcinoma refractory to prolonged hormonal treatment with megestrol acetate, presenting with adrenal insufficiency (AU)

Cost of management of invasive growth hormone-secreting macroadenoma.

BACKGROUND: At the time of diagnosis, macroadenomas represent 60-80% of GH secreting adenomas, of which 25-30% are invasive macroadenomas. These aggressive tumors have the worst surgical success rates in terms of cure, and often need several therapeutic approaches in order to control disease status. Acromegalic patients are subject to increased mortality and important health resource consumption related to their associated co-morbidities, in addition to the costs that are related to diagnosis itself and initial treatment of the disease. OBJECTIVE: Assessment of the cost of initial management and outcome of acromegalic patients with invasive pituitary adenomas. STUDY DESIGN: Retrospective and observational study of review of records. SETTING: Two tertiary hospitals. PATIENTS: 11 consecutive patients between 18 and 80 yr old diagnosed with acromegaly due to an invasive pituitary macroadenoma. INTERVENTION: Collection of data of biochemical and radiological tests, specialist visits, hospitalisation, surgery, pharmacological and radiotherapy treatment at diagnosis and over 4 yr of follow-up after initial treatment. Costs were evaluated using the data of the Centre for Health Economics and Social Policy Studies and the Official College of Pharmacists of Spain. MAIN OUTCOME MEASURE: Global and patient/yr follow-up costs of illness. RESULTS: The mean costs for acromegaly for the period of follow-up ranged from 7,072 to 9,874 euro/patient/yr, for biochemically non-controlled (no.=6) and controlled patients (no.=5) respectively. The most important cost in the perioperative period was for admission in the intensive care unit. After surgery, SS analogues were the principal contributors to the economic burden. CONCLUSION: In this paper we have for the first time presented a pharmacoeconomic study of GH secreting invasive macroadenoma. The poor prognosis of our cohort of patients and the higher rate of controlled patients and normal IGF-I levels warrant the employment of multiple therapeutic options. The cost associated with this treatment in this complex disease of low prevalence is not excessive and can be supported by healthcare services.

The role of diabetes duration, pubertal development and metabolic control in growth in children with type 1 diabetes mellitus.

OBJECTIVE: To investigate whether pubertal development, duration of type 1 diabetes mellitus (DM1), or metabolic control play some role in the anomalies in growth observed in diabetic children. PATIENTS: We conducted a prospective evaluation of 83 patients (37 female, 46 male) who were followed from the onset of DM1 at the prepubertal stage until they reached final height. All patients were treated with a conventional regimen of insulin. METHODS: Height SDS, weight SDS, BMI SDS, duration of DM1 in years, and values of HbA1c were the study variables. RESULTS: In prepubertal (P1) girls (data for the initial vs the intermediate evaluations): weight SDS was -0.14 +/- 0.19 vs 0.11 +/- 0.20, p = ns; BMI SDS -0.25 +/- 0.15 vs 0.01 +/- 0.13, p = ns. In postpubertal (P3) girls, weight SDS was 0.49 +/- 0.2 vs 1.2 +/- 0.32, p <0.01; BMI SDS 0.09 +/- 0.16 vs 1.03 +/- 0.24, p <0.01, whereas in P1 boys, height SDS was 0.16 +/- 0.30 vs -0.20 +/- 0.27, p <0.05; and in P3 boys: 0.09 +/- 0.21 vs -0.28 +/- 0.26, p <0.05. Thus pubertal development influenced changes observed in girls with DM1, but did not do so in boys. The anomalies described in children with DM1 were observed from the third year of DM1 duration in both girls and boys. We did not observe any correlation between HbA1c values with height SDS, weight SDS or BMI SDS. CONCLUSIONS: The anomalies in growth observed in girls with DM1 are related to pubertal development, but this is not the case in boys. Alterations in children with DM1 were found from the third year of DM1 duration. Furthermore, the present data also indicate that the degree of metabolic control observed in our patients treated with modern but conventional regimen did not play a major role in the anomalies observed.

Características demográficas y clínicas de 69 pacientes con hipopituitarismo diagnosticado en la edad adulta / Demographic and clinical characteristics of 69 patients with hypopituitarism diagnosed in adulthood

Introducción: La disponibilidad de hormona de crecimiento (GH) recombinante y las evidencias acumuladas de su beneficio en el tratamiento del adulto deficitario han despertado un interés creciente por el hipopituitarismo, aunque los estudios poblacionales son escasos. El objetivo de nuestro trabajo fue mostrar las características demográficas y clínicas más relevantes de los pacientes hipopituitarios identificados en un estudio de prevalencia. Pacientes: Se estudió a 69 pacientes diagnosticados de hipopituitarismo en la edad adulta que pertenecían a la población atendida por el hospital Xeral-Cíes de Vigo (España) y sus centros primarios y secundarios asociados en 1999.Resultados: No hubo diferencia de frecuencia entre sexos y la edad al diagnóstico fue 50 ñ 17 años. Predominaron las causas tumorales (70 por ciento), especialmente en los varones. La mayoría de nuestros pacientes (65 por ciento) resultaron deficitarios en 3 o más ejes hormonales (un 63 por ciento en los casos tumorales y un 71 por ciento en los no tumorales). El eje gonadotropo fue el afectado con más frecuencia. El eje somatotropo resultó deficitario en el 66 por ciento de los casos tumorales y siempre que había más de 3 ejes afectados. Se sustituyeron de manera habitual los ejes corticotropo, tirotropo y la vasopresina, pero el eje gonadotropo se sustituyó sólo en el 41 por ciento de los pacientes deficitarios y el somatotropo, en el 7 por ciento. Conclusiones: Entre las características de nuestros pacientes, destacan el predominio de las gonadotropinas como eje deficitario, la afección del eje somatotropo siempre que estaban afectados más de 3 ejes, y la todavía baja frecuencia de sustitución de esteroides sexuales y GH (AU)

Masa hipofisaria clínicamente silente encontrada de forma casual / Incidentally discovered pituitary lesion clinically silent

En los últimos años, la amplia utilización de las técnicas de neuroimagen ha condicionado el descubrimiento, cada vez más frecuente, de lesiones hipofisarias asintomáticas. Aunque su etiología es muy variada, la mayoría de los incidentalomas hipofisarios son adenomas benignos, tanto los microadenomas ( 10 mm). Las microlesiones son tan frecuentes que pueden aparecer en el 4-30 por ciento de los estudios de imagen en individuos normales. La evaluación y el tratamiento son controvertidos y varían ampliamente entre endocrinólogos. A propósito de un caso clínico, discutiremos la actitud diagnóstica y terapéutica, diferenciando entre microlesiones y macrolesiones incidentales (AU)

Factors associated with mortality of patients with myxoedema coma: prospective study in 11 cases treated in a single institution.

This study was carried out to investigate the clinical and biochemical factors which might be of importance in predicting the outcome of patients with myxoedema coma. Eleven patients (ten female) aged 68.1+/-19.5 years attended our institution over a period of 18 years. Glasgow and APACHE II scores and serum free thyroxine and TSH were measured in all the patients on entry. Patients were selected at random to be treated with two different regimens of l-thyroxine. Four patients died with the mortality rate being 36.4%. The patients in coma at entry had significantly higher mortality rates than those with minor degrees of consciousness (75% vs 14.3% respectively, P=0.04). The surviving patients had significantly higher Glasgow scores than those who died (11.85+/-2.3 vs 5.25+/-2.2 respectively, P<0.001). Comparison of the mean values of APACHE II scores between the surviving group and those who died was significantly different (18.0+/-2.08 vs 31.5+/-2.08 respectively, P<0.0001). The degree of consciousness, the Glasgow score and the severity of the illness measured by APACHE II score on entry were the main factors that determined the post-treatment outcome of patients with myxoedema coma.

A single growth hormone (GH) determination is sufficient for the diagnosis of GH-deficiency in adult patients using the growth hormone releasing hormone plus growth hormone releasing peptide-6 test.

BACKGROUND: The diagnosis of GH deficiency in adults is based on the provocative testing of GH secretion. When testing a patient with suspected GH deficiency, clinicians assess the whole secretory curve and select the GH peak as an index of secretory capability. This procedure is time consuming and the determination of GH in several samples is necessary. The combined administration of growth hormone releasing hormone (GHRH) plus growth hormone releasing peptide-6 (GHRP-6) is an effective test of GH secretion, and it has been unambiguously demonstrated that the elicited GH peak is capable of segregating normal GH secretion subjects from GH deficient patients on an individual basis. The GHRH + GHRP-6 test biochemically classifies patients into three groups; those with a stimulated GH peak >/= 20 micro g/l are considered normal and those with peaks at

Acromegaly Quality of Life Questionnaire (ACROQOL) a new health-related quality of life questionnaire for patients with acromegaly: development and psychometric properties.

OBJECTIVE: To develop a disease-specific questionnaire suitable to measure health-related quality of life (HRQOL) in acromegaly (ACROQOL). DESIGN, PATIENTS AND MEASUREMENTS: For the development of the ACROQOL questionnaire different sources of information were used: First, a literature search was performed to identify relevant papers describing the impact of acromegaly in HRQOL. Second, 10 endocrinologists identified the main domains of impact on HRQOL in patients with acromegaly. Third, 10 in-depth, semistructured interviews were conducted in acromegalic patients to identify domains and items related to the self-perceived impact of acromegaly in patients' life. Qualitative analyses of the information were performed identifying domains and items to be included in the questionnaire. Those items considered ambiguous, complicated to read, double-barrelled, with jargon terms, too long, or negatively worded were excluded. Each remaining item was subsequently rated by the same panel of endocrinologists and experts in HRQOL evaluation, and assessed according to clarity of wording, frequency of occurrence and importance among patients with acromegaly. Analysis of internal consistency of the questionnaire was evaluated with a Cronbach's Alpha. A preliminary questionnaire was administered to 72 patients with acromegaly. Rasch analysis (dichotomous logistic response model) of the answers given by these patients allowed parameter estimates and model data fit indices to be computed and misfitting items deleted. Frequency of occurrence and degree of agreement with the statements were selected as response choices in a 5-point Likert type scale. RESULTS: The following domains related to HRQOL in acromegaly were identified: physical and psychological functions, social, daily activities, symptoms, cognition, general health perception, sleep, sexual function, pain, energy and body image. An initial set of 204 expressions were identified from the initial transcripts of the patient interviews. After elimination of ambiguous or unclear expressions, 142 items remained drafted in question form. From the quantitative analysis of the item rank position within each of the three areas of clarity, frequency and importance, the 38-item questionnaire was produced, with satisfactory internal consistency (Cronbach's Alpha 0.94). Rasch analysis produced a further reduction to the final 22-item questionnaire (Cronbach's Alpha 0.91) containing two scales that evaluate physical (eight questions) and psychological aspects related to appearance and personal relations (seven items each). The evaluation of the item parameters confirmed the construct validity of the new instrument. The substantial reliability of the questionnaire suggested the sample was well targeted by the questionnaire. The initial Spanish version was translated into English and presented to five English-speaking Australian patients with acromegaly to assess and correct for comprehension, clarity, cultural relevance and suitable wording. CONCLUSIONS: We present the ACROQOL questionnaire, developed and preliminarily validated to specifically assess HRQOL in patients with acromegaly.

Intrasellar tuberculoma--a difficult diagnosis.

Tuberculosis is an exceptional cause of intrasellar mass lesion and diagnosis is usually established after histological examination following surgery. We report a 32-year-old woman with headache and amenorrhea, analytical features of hypopituitarism and an intrasellar mass lesion in radiological studies. A transsphenoidal approach was performed and tissue examination revealed pituitary tuberculoma. Additionally, we review the previously reported cases.

Monitoring of treatment success in patients with acromegaly: the value of serum insulin-like growth factor binding protein-3 and serum leptin measurements in comparison to plasma insulin-like growth factor I determination.

The aim of the present study was to determine the value of serum insulin-like growth factor binding protein-3 (IGFBP-3) and serum leptin measurements in comparison with plasma insulin-like growth factor I (IGF-I) measurements as indicators of treatment success in patients with acromegaly. Thirty-five acromegaly patients, 25 female and 10 male, divided into groups of patients with postadenomectomy "active" acromegaly (n = 20) and patients with postadenomectomy "controlled" acromegaly (n = 15), and 44 healthy volunteers sex- and age-matched with the acromegaly patients were included in the present study. We comparatively analyzed plasma IGF-I, serum IGFBP-3, and serum leptin levels in the aforementioned groups. Because serum leptin has sex dimorphism, the groups were divided into sexes when leptin was evaluated. As expected, the patients with active acromegaly had significantly higher mean values of plasma IGF-I and serum IGFBP-3 and lower mean values of serum leptin (only in women) than the control group. However, individual evaluation showed that 1 of 20, 9 of 20, and many patients with postadenomectomy active acromegaly patients had values that overlapped values of control subjects for plasma standard deviation score (SDS)-IGF-I, serum SDS-IGFBP-3, and sex-adjusted serum leptin, respectively. Application of the receiver operating characteristic (ROC) curves method shows that plasma IGF-I measurement has the best discriminatory power to differentiate patients with postsurgical active acromegaly from healthy people. Its area under the curve (AUC) was 0.95, with a sensitivity and specificity of 86% and 94%, respectively. Its positive and negative likelihood ratios were 14 and 0.15. Serum IGFBP-3 has certain discriminatory power, its AUC being 0.89, with a sensitivity and specificity of 83% and 77%. Its positive and negative likelihood ratios were 3.6 and 0.22. Serum leptin, both in women and in men, has a poor performance with sensitivity and specificity of 53% and 50% for women and 55% and 56% for men and positive and negative likelihood ratios of 1.06 and 0.94 for women and 1.26 and 0.8 for men. Application of the ROC curves method and the determination of positive and negative likelihood ratios in comparative evaluation of serum IGFBP-3 and serum leptin with plasma IGF-I as indicators of treatment success in acromegalic patients showed that neither serum IGFBP-3 nor serum leptin determinations have accuracy better than or similar to that of plasma IGF-I for monitoring treatment success in acromegaly patients. Serum IGFBP-3 is accurate but does not increase accuracy for age-adjusted plasma IGF-I, whereas determination of serum leptin level has no value in monitoring these patients.

Unusual presentation of a pancreatic insulinoma in helical CT and dynamic contrast-enhanced MR imaging: case report.

Insulinomas are pancreatic neoplasms that can be radiologically characterized typically because of their tendency to present intense and early contrast enhancement with a wash-out phenomenon. In this sense, we report an unusual case of a hypovascular solid pancreatic insulinoma confirmed with surgery and pathologic analysis, in a patient with normal serum insulin levels. In the two-phase helical CT, the mass behaved as a hypodense lesion with respect to the surrounding pancreatic parenchyma during the arterial phase and as a hypointense lesion during the dynamic contrast-enhanced MR imaging. Pathologic examination demonstrated a hypercellular tumor with poor vascularization of intervening stroma which showed prominent amyloid deposits.

Prevalence and incidence of hypopituitarism in an adult Caucasian population in northwestern Spain.

OBJECTIVE: To determine the prevalence and incidence of hypopituitarism in the general population. POPULATION: The study population comprised an average population sample of 146,000 adult inhabitants in South Galicia (northwestern Spain). The Medical Register of the General Hospital of Vigo ensured virtually complete case ascertainment for diagnosed hypopituitarism in this sample population. Only patients residing in the study area were included. The diagnosis of hypopituitarism was based on baseline and hormonal dynamic tests. DESIGN: The study comprised two cross-sectional surveys, the first from January to December 1992 and the second from January to December 1999, together with a longitudinal survey performed between January 1993 and December 1999. MAIN RESULTS: In the first survey the prevalence of hypopituitarism was 29/100,000 (CI, 19.88-37.72), without sex differences. In the second survey, the prevalence observed was higher than in the first, 45.5/100,000 (CI, 34.92-56.08). In the second survey, which included almost all cases registered in the first study, the cause of hypopituitarism was a pituitary tumour in 61%, a non-pituitary tumour in 9% and a non-tumour cause in 30%. Around 50% of patients had 3-5 pituitary hormonal deficiencies, with LH/FSH being the most prevalent. Patients with tumour-induced hypopituitarism showed a tendency to suffer GH deficiency more frequently than those due to non-tumour causes. In the longitudinal study with a population of 1,020,764 people-years of observation, the average annual incidence rate of hypopituitarism was 4.21 cases/100,000 (CI, 2.95-5.47), with this incidence being similar for both sexes. The annual incidence of hypopituitarism remained stable during the study period. CONCLUSION: We present for the first time data on the prevalence and incidence of hypopituitarism in the general adult population. These patients showed a tendency to suffer LH/FSH deficiency as the most prevalent hormone deficit. Furthermore, patients with hypopituitarism due to a tumour or its treatment showed a greater tendency to suffer GH deficiency than those with a non-tumour cause. These data may be useful for producing a rational programme for patients suffering from this condition and also for comparison with future data in our country and elsewhere in the world.

GH-releasing hormone and GH-releasing peptide-6 for diagnostic testing in GH-deficient adults.

BACKGROUND: The diagnosis of growth hormone (GH) deficiency in adults is based on provocative testing of GH secretion. The insulin tolerance test (ITT), currently the favoured test for this diagnosis, has been criticised for poor reproducibility and inconvenience. Since the combined administration of GH-releasing hormone (GHRH) plus GH-releasing peptide-6 (GHRP-6) is the most potent stimulus of GH secretion, we did a multicentre study comparing GH peaks elicited by ITT with those elicited by the GHRH/GHRP-6 test in healthy controls and GH-deficient individuals (cases). METHODS: 125 adult patients with organic pituitary disease and 125 healthy individuals were studied. All cases and controls were given GHRH 1 microg per kg bodyweight intravenously plus GHRP-6 1 microg per kg intravenously at 0 min and blood samples were obtained during a subsequent 120 min period. 27 controls and all cases had an ITT. Inclusion criteria were severe GH deficiency--ie, a GH peak after ITT of < or = 3 microg/L. Results of the GHRH/GHRP-6 test were analysed by receiver-operating characteristic curve methodology. FINDINGS: GH peaks seen after the GHRH/GHRP-6 test did not result in any side-effects and were not affected by age, sex, amount of adipose tissue, or by the GH assay system used. The GH mean peak after the GHRH/GHRP-6 test was 59.2 microg/L (SD 2.2) for controls and 4.1 microg/L (0.3) for cases, whereas after ITT the mean peak was 14.3 microg/L (1.7) and 0.5 microg/L (0.06), respectively. The differential peak responses of controls and cases was greater (p<0.001), for GHRH/GHRP-6 test than for ITT. When individually analysed GH peaks were a continuum, from 139.0 microg/L to 0.01 microg/L, with a cut-off point of 15.0 microg/L. The GHRH/GHRP-6 test performed well under the ROC curve analysis. For clinical utility, it is then proposed that values > or = 20.00 microg/L be considered normal and < or = 10.00 microg/L as GH deficient. INTERPRETATION: The GHRH/GHRP-6 test is a convenient, safe and reliable test for adult GH deficiency and is not confounded by clinical factors known to alter GH secretory patterns. An evoked GH concentration of > or = 15.0 microg/L accurately distinguishes between healthy and GH-deficient adults.

MR imaging findings in granular cell tumor of the neurohypophysis: a difficult preoperative diagnosis.

Granular cell tumor is a rare neoplasm arising within the neurohypophysis. We describe the MR imaging findings in two symptomatic patients. In one patient with history of panhypopituitarism, MR images showed a large sellar and suprasellar mass. The other patient presented with acute loss of vision in her left eye, and MR images showed a suprasellar mass with compression of the optic chiasm.

Coexistence of primary hyperparathyroidism and thyroid disease.

Primary hyperparathyroidism (HPT) and thyroid disease are both relatively common diseases, which can coexist in the same patient. However, mere coincidence does not seem to be a satisfactory explanation for this association. Some factors like prior exposure to radiation may play a role in the association. The aim of this study was to determine the frequency of thyroid disease associated with HPT in 54 consecutive patients who underwent parathyroidectomy in our center from January 1990 to December 1997. Twenty-eight (52%) patients had thyroid disease associated to HPT. The patients had a mean age of 61+/-13 yr; they were predominantly postmenopausal women. Thyroid disease was detected preoperatively in 20 (71%) patients and during the surgical procedure in 8 (29%). Two patients had previous radiation exposure; one of them with papillary carcinoma of the thyroid. Two patients had hypothyroidism. UItrasonography was performed in the majority of patients in their preoperative evaluation. A multinodular goiter was seen to be the most frequent finding (76%). In addition to parathyroidectomy, 23 (82%) patients were also thyroidectomized. In conclusion, patients with HPT showed a high prevalence of thyroid disease, especially in postmenopausal women. Unsuspected thyroid lesions were found with sufficient frequency to warrant careful preoperative and intraoperative evaluation of both glands, in order to obviate reoperation. In experienced hands, combined surgery can be safely performed. Cervical ultrasonography is useful in the preoperative detection of nodular thyroid disease in these patients.
