Posterior retroperitoneoscopic adrenalectomy: a comparison between the initial experience in the invention phase and introductory phase of the new surgical technique.

BACKGROUND: Today, the posterior retroperitoneoscopic technique has become a standard procedure in adrenal surgery. The procedure allows direct access to the adrenal glands, but it seems to be difficult because of the uncommon anatomic view. This study compares the learning period of the new procedure of "posterior retroperitoneoscopic adrenalectomy" in the primary invention phase and the secondary introductory phase in a different hospital 10 years later. MATERIALS AND METHODS: The analysis included 100 posterior retroperitoneoscopic adrenalectomies (PRA) and involved 50 procedures in each center. Group A consisted of 44 patients (14 males, 30 females; age: 48.7 +/- 14.5 years) undergoing surgery between 07/1994 and 8/1996 (24 right, 26 left; 8 Cushing adenomas, 14 Conn adenomas, 11 pheochromocytomas, 7 nonfunctioning adrenocortical adenomas, 10 ACTH-dependent adrenal hyperplasias). Group B consisted of 50 patients (12 males, 38 females; mean age 59.3 +/- 10.7 years) operated between 01/2004 and 01/2006 (28 right, 22 left tumors; 5 Cushing adenomas, 12 Conn adenomas, 4 pheochromocytomas, 29 nonfunctioning adrenocortical adenomas). All PRAs were performed with the patient in the prone position with 3-4 trocars placed caudally in the region of the 11th and 12th ribs. In group A, the surgical team developed the technique of PRA themselves. Before their first PRA, the surgical team of group B was introduced to the technique by the group A surgeons and afterwards were supervised continuously. RESULTS: No serious intraoperative or postoperative complication occurred in either group. Group A experienced 7 conversions to open surgery, whereas group B had one conversion and one early reoperation due to bleeding (P = 0.03; chi(2)-test). The mean operative time was 117 +/- 41 minutes versus 83 +/- 35 minutes (group A and B respectively; P < 0.001; t-test). Estimated blood loss was similar in the two groups (47.2 +/- 46.2 ml versus 54 +/- 16.3 ml, group A versus B, respectively; P = 0.36; t-test). CONCLUSIONS: The study demonstrates the feasibility, safety, and reproducibility of the new surgical method of PRA both when it is employed in the early phase of invention, as well as when performed by surgeon-learners. After comprehensive training, the operative time and conversion rate are dramatically reduced, allowing for a short learning period.

[Evaluation of the efficacy of long-acting somatostatin analog as adjunctive therapy in patients with active acromegaly].

UNLABELLED: Transsphenoidal surgery is the first-line therapy for patients with acromegaly, but can achieve biochemical control with normalization of somatomedin C in 40-80% of cases. All patients with continued growth hormone hypersecretion after neurosurgery require adjunctive therapy to prevent morbidity and premature mortality. The aim of our study was to evaluate the efficacy of long-acting somatostatin analog--octreotide LAR (OCT-LAR) as adjunctive therapy for patients with persistent disease. 14 adult subjects (age 45 +/- 15 years) were included into the study. All patients were diagnosed as having growth hormone secreting pituitary tumor and underwent transsphenoidal surgery (TSS). Radiotherapy (RT) was used as adjunctive therapy in 7 of investigated persons. In all subjects elevated level of somatomedin C was found, 9 have increased level of growth hormone (hGH) as well. After 6 months therapy with OCT-LAR we noticed drop in somatomedin C and hGH levels in all patients. Mean drop in somatomedin C level was 42.3% (p=0.001), in GH level was 52.3% (p=0.001). We found entire normalization of GH in 12 (85.7%) patients, nearly normalization of somatomedin C (level lower than 110% of normal upper limit) in 8 (57%) patients. We found no significant correlation between decrease in somatomedin C and its level prior to the treatment (p=0.8), but high positive correlation between decrease in hGh level and its initial value (R=0.75, p=0.002). Decreases in both somatomedin C (p=0.7) and hGH (p=0.6) levels were not correlated with patients' age. The therapeutic outcome defined as decrease in somatomedin C level was not significantly different between patients with or without adjunctive radiotherapy in the past (p=0.08) and between patients with intensive or weak isotope collection in the pituitary in 99mTc-octreotide scintiscan (p=0.2). CONCLUSIONS: Octreotide-LAR efficiently reduces somatomedin C and GH levels in patients with active acromegaly. Initial values of somatomedin C as well as age and isotopic imaging findings are not valuable predictor factors for therapeutic outcome.

[New horizons for increased sensitivity of radionuclide imaging in primary hyperparathyroidism].

The aim of the study was to evaluate the impact of therapy with biphosphonates in patients with primary hyperparathyroidism and negative result of parathyroid scintigraphic imaging on increase of diagnostic sensitivity in repeated scans. Three female patients with diagnosed primary hyperparathyroidism and negative parathyroid imaging with subtraction 99m-Tc-MIBI scintigraphy were included into this prospective study. Patients had been receiving 70 mg of sodium alendronate orally, once a week for 3 months. After this period they were reevaluated with parathyroid subtraction scintigraphy. In all three patients a solitary area of uptake was found in the repeated scans. Patients were qualified for minimally invasive video-assisted parathyroidectomy. In two of them the repeated scans after treatment with biphosphonates were found to be true positive and in those two patients a solitary parathyroid adenoma was removed with video-assisted technique. In one patient a multiglandular disease was revealed intraoperatively basing on intraoperative iPTH assay and in that patient a subtotal video-assisted parathyroidectomy has been successfully completed. All three patients have been eucalcemic within the 6-months follow-up with iPTH serum values within the reference range. In conclusion, treatment with oral biphosphonates in patients with primary hyperparathyroidism and negative result of radionuclide parathyroid imaging, results in increased diagnostic sensitivity of repeated scans. This allows for successful minimally invasive parathyroid surgery in this group of patients with a predominant solitary parathyroid adenoma.

[A case of GH and TSH secreting pituitary macroadenoma].

A case of GH and TSH secreting pituitary macroadenoma is reported. A 45-year-old female presented clinical features of acromegaly (the abnormal growth of the hands and feet, with lower jaw protrusion), diabetes mellitus, hypertension, nodular goiter and hyperthyroidism of unclear origin. NMR pituitary imaging revealed intra and extrasellar tumor. The laboratory examinations showed very high plasma levels of GH and IGF-1 and normal level of TSH coexisting with high plasma levels of free thyroid hormones. Pharmacological pretreatment with somatostatin analogues caused the substantial reduction of GH and TSH plasma levels. Histological and immunohistochemical examination of the tissue obtained at transsphenoidal surgery showed GH and TSH secreting adenoma. The laboratory examinations after surgery showed normal GH and IGF-1 plasma levels and reduced insulin requirement, what indicates radical operation. The very low plasma levels of TSH and free thyroid hormones after surgery and immunohistochemical examination suggest central hyperthyroidism due to TSH secreting pituitary tumor (thyrotropinoma).

[Studies on iodine deficiency in adult population of Cracow].

The aim of the study carried out in 1989-90 and 1998-99 was to define the iodine deficiency state and goiter prevalence in adult population of Cracow. The analysis included data obtained from 230 individuals (143 females and 87 males). The mean age was 36 +/- 15 years. The thyroid size and morphology was determined by ultrasound method using Aloka unit equipped with 7.5 MHz linear transducer. The concentration of iodine in casual morning urine sample was measured using Sandell-Kolthoff's method. The 10- year observation revealed an insignificant decrease in prevalence of goiter from 26.2% to 21.8%. We observed statistically significant (p = 0.001) decrease in the parenchymal goiter prevalence from 22.7% to 11.7 in the same period of time. The significant increase in incidence of nodular goiter was found (6.5% vs 20.8%, p < 0.001). In all groups investigated through 1989-99, there was an increase in medians of ioduria over the 10-year period. The level of urinary iodine excretion was not essential element for risk of nodular goitre. Thus, the results indicate the beneficial effect of iodine prophylaxis which reflects in decrease of prevalence of parenchymal goiter. No clear effect of iodine prophylaxis was noticed regarding rise in nodular goiter incidence.

[Changes in thyroid volume after radioactive iodine therapy in patients with single toxic thyroid nodule].

Radioactive iodine (131I) is a well-established therapeutic modality in the treatment of toxic solitary autonomous thyroid nodules. This method is preferred in patients with small, benign nodules. The aim of our study was to investigate the effects of radioiodine therapy on thyroid size in patients with a solitary toxic thyroid nodule. 22 patients with single nodule in USG and confirmed "hot" nodule in scintigraphy were enrolled in the study. Thyroid and nodule volume were determined by ultrasound before, 3 and 6 months after the administration of 131I. Thyroid function was assessed by TSH level prior to the treatment and 6 weeks after the therapy. Thyroid volume and nodule size decreased significantly within 3 and 6 months after 131I treatment. The mean reduction of thyroid volume within 6 month after treatment was 32%. Reduction in thyroid volume and nodule, size was significantly greater within first 3 months than within next 3 months. Patients with smaller nodules (less than 70% of thyroid volume) were characterized by greater reduction of goiter size than patients with nodules bigger or equal to 70% of thyroid volume.

[Disturbances of thyroid function in adult population of the city of Cracow followed up for ten years observation].

UNLABELLED: The aim of the study was to define disturbances of thyroid function in adult population of the city of Cracow followed up for ten years. The analysis included the results obtained from 891 individuals, 571 females and 320 males aged 18-78 years examined prior to and after implementation of the obligatory model of iodine prophylaxis (years 1989-1990 and 1998-1999). After the exclusion of patients diagnosed earlier as having hyperthyroidism or hypothyroidism, the mean TSH level in the years 1998-1999 was significantly higher as compared to data obtained between 1989 and 1990 (1.44 microj/ml vs. 1.30 microj/ml) in the examined population. Our 10 years observation revealed an insignificant increase in frequency of hyperthyroidism only among females (1.6% vs. 0.9%) which did not indicate a clear, endemic in character increase at the population level. In the present investigations, hypothyroidism was demonstrated to occur more frequently as compared to the 1989-90 study (2.1% vs. 1.4% among females and 0.3% vs. 0% in males). Both differences were not statistically significant. As seen from the present results, over the investigated 10-year period, in the Cracow population, there occurred a clear, statistically significant (p<0.001) increase of the percentage of individuals with an elevated TPO antibody titter (3.8% vs. 11.8%). In our investigation no correlation was observed between anti-TPO antibodies and ioduria levels. CONCLUSIONS: The results reveal no statistically significant increase in incidence of hyperthyroidism and hypothyroidism after implementation of the obligatory model of iodine prophylaxis. The future studies are needed to clarify the mechanisms involved in increase of anti-TPO autoantibodies and verify its possible temporary nature.

[Diagnostic problems with recognition of primary hyperparathyroidism].

The aim of our study was to compare the results of biochemical and imaging investigations with histopathological diagnosis in operated patients with primary hyperparathyroidism. 46 subjects were included into the study, pathologically demonstrated as parathyroid adenoma--23 subjects, parathyroid hypertrophy--16, parathyroid carcinoma--2 and in 5 patients parathyroid gland was not found in resected tissue. The most frequent complications of primary hyperparathyroidism in our group were osteoporosis (87%) and nephrolithiasis (64.1%). 99mTc-MIBI imaging described as a parathyroid adenoma or parathyroid hypertrophy were confirmed pathologically in 52 and 57.1%, respectively. Three typical symptoms of primary hyperparathyroidism assessed in our study (hypercalcemia, hypercalciuria and increased concentration of parathormone) were observed only in about 50% patients with histopathological diagnosis of adenoma and hypertrophy. The lowest average calcium serum level (2.87 mmol/l), urinary calcium level (7.8 mmol/24h) and parathyroid hormone concentration (209.4 pg/ml) were observed in patients with parathyroid adenoma, the highest levels of these parameters were noticed in patients with parathyroid carcinoma (3.41 mmol/l; 14.6 mmol/24h; 687.8 pg/ml, respectively), patients with parathyroid adenoma were characterized by intermediate values (2.98 mmol/l; 9.7 mmol/24h; 285.5 pg/ml, respectively). After parathyroidectomy lowering in average calcium serum level (2.94 vs. 2.16 mmol/l), parathyroid hormone concentration (244.45 vs. 54.15 pg/ml) and increasing in average phosphate serum level (0.81 vs. 1.04 mmol/24h) were observed in our group. Finally, using different biochemical and imaging investigations is necessary for proper recognition of primary hyperparathyroidism due to occurring of oligosymptomatic cases.

[Adrenal incidentaloma as essential clinical problem in modern endocrinology].

Adrenal mass discovered during imaging for non-adrenal related causes is called incidentaloma. Adrenal masses can be asymptomatic or can have clinical manifestations related to hormone overproduction. The increasing number of discovered adrenal mass is by no doubt due to quick development of radiology procedures. The aim of study was determination of statistical frequency of different types of adrenal tumours and related clinical symptoms based on retrospective analysis of patients diagnosed in the Department of Endocrinology, Collegium Medicum, Jagiellonian University. There were 271 patients (184 female, 87 male) with incidentaloma confirmed in CT scan from January 2000 to June 2005. Mean patients' age was 56.8 +/- 12.7 years. The most common localisation was right adrenal gland (135 cases), bilaterally in 29 patients. Tumours less than 3 cm in diameter were observed in 58.5% of diagnosed persons, tumours from 3 to 6 cm in 33.3% of cases and tumours bigger than 6 cm in 8.2% patients. Hormone excess associated with adrenal mass was detected in 37 (13.6%) patients. Pheochromocytoma was diagnosed in 20 patients (7.4%). Subclinical hypercortisolism was found in 13 patients (4.8%). Primary hyperaldosteronism was diagnosed in 4 cases (1,4%). In patients with adrenal mass incidentaloma hormone tests should be performed before making therapeutic decisions despite no clinical symptoms.

[Preoperative diagnostics in patients with adrenal tumors].

The aim of the study was analysis of preoperative diagnostics of patients who underwent laparoscopic adrenalectomy. In the preoperative diagnostics in 10 patients (22.2%) pheochromocytoma was found, in 8 (17.8%) Conn's syndrome, in 4 (8.9%) Cushing's syndrome and in 1 (2.2%) adrenal virilization. Full accordance between histopathological findings and preoperative diagnosis was achieved in 91% of cases. Four cases of discrepancy were: 1 false positive preoperative diagnosis of aldosteronoma, 1 false positive and 2 false negative diagnosis of pheochromocytoma.

[Evaluation of accordance between cytological and histopathological findings in selected thyroid tumors].

The thyroid fine-needle aspiration (FNA) is the decisive examination in the preoperative diagnostics of thyroid nodules. Different cytohistologic studies have revealed that the accuracy of FNA for thyroid nodules varied from 69% to 94%. The aim of our study was to compare the results of FNA with regard to final histopathological diagnosis among patients with follicular tumor, Hurthle cell tumor or papillary carcinoma in FNA. We retrospectively analyzed medical documentation of 51 patients (mean age 57.9 years, 49 women and 2 men) from the Endocrinology Department from 1997 to 2002 years. Based on FNA 29 patients were diagnosed as having follicular tumor, 10 as having Hurthle cell tumor and 12 as having papillary carcinoma. Carcinoma was detected histopathologically in 38% of patients with follicular tumor. Follicular carcinoma was detected histopathologically in 10% of patients with Hurthle cell tumor. Cytological diagnosis was confirmed histopathologically in 66.8% of all patients with papillary carcinoma in FNA. In accordance with our results the confirmation of malignant neoplasm can be expected in more than 80% of cases with papillary carcinoma in cytological examination. In case of follicular or Hurthle cell tumors the frequency of malignant neoplasm was less than 40% and 10% respectively.

[Assessment of early immunosuppressive therapy in the prevention of complications of Graves' disease].

UNLABELLED: Regardless the autoimmune origin of Graves' disease, the preferred method of its treatment remains antithyroid drug administration. Use of immunosuppressive agents (mostly steroids) is still limited to the therapy of disease complications, such as proliferative ophthalmopathy. The aim of the study was to assess the influence of early immunosuppressive treatment of autoimmune thyrotoxicosis with azathioprine on the course of the disease and the incidence of its complications. The study comprised 64 patients (47 females and 17 males aged 20-43 years) for the first time diagnosed with Graves' disease. The subjects were randomised into two groups. Group I consisted of 28 patients treated only with antithyroid drugs, the remaining 36 subjects additionally receiving azathioprine were included into group II. The dose of both drugs was adjusted during the treatment according to metabolic status of each patients. The treatment was continued for 8-14 months, the follow-up duration after therapy withdrawal was 5 years. Euthyreosis was achieved in all patients 2-8 weeks after treatment initiation. No drug intolerance symptoms were observed in group I. In four patients additionally treated with azathioprine, gastrointestinal side effects or leucopenia were present. The disease relapse was observed during the follow-up period in 15 (53.5%) patients of group I and in 3 (8.3%) of group II, the difference was statistically significant (p<0.01). Only one patient receiving additionally azathioprine presented ophthalmic symptoms compared with seven subjects (25%) treated only with antithyroid drugs (p<0.001). The patients of group I were also more frequently referred to surgical treatment due to rapid goitre growth (accordingly 5 (17.8%) and 1 (2.7%) patients, p=0.07), the difference between both groups not being statistically significant. CONCLUSIONS: Additional early immunosuppressive treatment significantly decreased frequency of Graves' disease complications and thyrotoxicosis recurrence. The use of azathioprine may be advised in patients with contraindications to the radical Graves' disease treatment and in prophylaxis of its complications.

[Postprandial hypotension and gastric emptying in longstanding diabetes mellitus].

UNLABELLED: Postprandial hypotension is commonly defined as a decrease in systolic blood pressure of 20 mmHg and more within 2 hours after meal ingestion. It was described in autonomic nervous system failure of different origin, among others in diabetes mellitus. Pathomechanism of postprandial hypotension is not entirely understood. The rol of gastric emptying disorders is considered as an important factor. The aim of the study was to evaluate the concordance between gastric emptying and postprandial blood pressure changes in diabetic patients. The study involved 67 subjects (26 males, 41 females, mean age: 47.5 +/- 16.2 years) diagnosed either with diabetes mellitus type 1 or 2 (disease duration: 13.3 +/- 8.8 years) and treated with diet and insulin injections. Postprandial hypotension was recognised based on results of automatic blood pressure recordings within 90 minutes after test meal ingestion, according to the criterion mentioned above. Gastric emptying was assessed scintigraphically. The parameters evaluated were: gastric half emptying time (T1/2 max) and residual activity registered over stomach area at 45 minute of the study. Both blood pressure monitoring and gastric emptying were assessed concurrently. In investigated patients mean fall in systolic blood pressure of 17.7 +/- 11.7 mm Hg was recorded at 48.0 +/- 13.7 min of the study. Based on systolic blood pressure monitoring results patients were divided into two groups: group A of 39 patients (58.2%) without postprandial hypotension, and group B of 28 patients (41.8%) with pathological reaction of systolic blood pressure to meal. The average decrease in systolic blood pressure was 8.9 +/- 4.4 mm Hg in group A and 30.0 +/- 6.2 mmHg in group B, the difference was statistically significant (p < 0.001). Gastric emptying parameters in both groups did not differ significantly (T1/2 max: group A 68.4 +/- 31.1; group B 70.8 +/- 39.1 min, p = 0.96; residual activity over stomach area at 45 min of the study: 64.5 +/- 18.6% and 62.6 +/- 24.3% accordingly, p = 0.80). No statistically significant correlation between gastric emptying half time (T1/2 max) and magnitude of postprandial systolic blood pressure fall was noted (Spearman's correlation co-efficient R: -0.041, p = 0.74). Statistically significant correlation was found between T1/2 max value and time in which systolic blood pressure reached its nadir (Spearman's correlation co-efficient: 0.527, p < 0.0001). CONCLUSIONS: Gastric emptying was not recognised as an important factor influencing the magnitude of postprandial hypotension in diabetic patients, however it may significantly change the dynamics of postprandial blood pressure decrease.

[Pituitary tumors: hormonal status and immunohistochemical evaluation].

UNLABELLED: New imaging modalities and hormonal diagnostic improvement have markedly increased the number of newly recognized pituitary tumours. Introduction of immunohistochemical assays in histopathological diagnostics of pitutary adenomas resulted in better understanding of pathology and clinics of these neoplasms. The aim of the study was to correlate the hormonal status and hematoxylin-eosin staining results with immunohistochemical staining of pituitary tumours. The study included 40 patients aged 43.8 +/- 18.3 years, diagnosed with a pituitary tumour in the Department of Endocrinology Collegium Medicum UJ, who subsequently underwent trans-sphenoidal surgery in the Department of Neurosurgery Collegium Medicum UJ. The serum pituitary hormone levels were assessed by means of radioimmuno-assays. The surgically obtained tumour tissue was evaluated both by hematoxylin-eosin and immunohistochemical staining. Using traditional staining 33 patients were diagnosed with chromophobic adenoma, 1 with basophilic adenoma, and remaining 6 with eosinophilic tumour. Immunohistochemical assays were ACTH-positive in 16, TSH-positive in 7, GH-positive in 14 and PRL-positive in 17 cases. In 15 subjects immunohistochemical staining was positive for at least two pituitary hormones. In 34 of 54 patients with positive immunohistochemical staining results, no increase in corresponding pituitary hormone serum levels was observed. In 5 of 9 patients with negative immunohistochemical staining, no increase in serum hormone level was noted, remaining 4 were characterized by hyperprolactinaemia. Tumour cells were ACTH-positive in 5 of 6 patients with elevated serum ACTH levels and GH- or TSH-positive in all cases of increased levels of these hormones. Only 6 of 15 subjects with hyperprolactinaemia revealed positive PRL immunohistochemical staining. CONCLUSIONS: Positive immunohistochemical staining often do not correlate with elevated basal serum pituitary hormone levels, which may be related to either impaired synthesis or excretion of the hormones by tumour cells. Increased serum levels of ACTH, TSH or GH are usually connected with positive immunohistochemical staining results. Hyperprolacinaemia in cases of PRL-negative assays arises from PRL secretion defects caused by the tumour presence itself.

[Unilateral exophthalmos during the course of cavernous sinus thrombosis: a case report].

Ophthalmopathy, particularly its infiltrative form, is considered a characteristic feature of Graves' disease. However many other also life-treating conditions may be manifested as unilateral exophthalmos and lead to diagnostic problems. A case of a sixty six-year old patient with asymmetric exophthalmos and rapidly decreasing vision acuity is reported. Thyroid eye disease was suspected due to clinical symptoms (diplopy, impaired right eye motion) and thickening of extraocular muscles in ultrasound imaging. Further follow-up and orbits as well as head MRI imaging led to the final diagnosis of cavernous sinus thrombosis, complication of acute maxillary sinusitis.

[Postprandial hypotension and autonomic neuropathy in diabetic patients].

UNLABELLED: Postprandial hypotension is commonly defined as the decrease in systolic blood pressure of 20 mm Hg and more, observed within 2 hours after meal ingestion. This phenomenon was described in subjects with comprised function of autonomic nervous system. However, the data on its prevalence in diabetic patients are scarce. The aim of the study was to assess the concordance of postprandial hypotension and autonomic cardiovascular neuropathy in diabetes mellitus. The study included 67 patients (26 males, 41 females, mean age: 47.5 +/- 16.2 years) with diabetes type 1 or 2 (mean disease duration: 13.3 +/- 8.8 years), treated with diet and insulin injections. Postprandial hypotension was diagnosed based on results of automatic blood pressure recordings performed within 90 minutes after test meal ingestion. Tests of Ewing's battery were used to evaluate autonomic cardiovascular neuropathy. RESULTS: Mean postprandial decrease in systolic blood pressure of 17.7 +/- 11.7 mm Hg was noted at 48.0 +/- 13.7 min after meal ingestion. The study patients were divided into 2 groups based on results of systolic blood pressure recordings. In group A of 39 subjects (58.2%) the mean fall in systolic blood pressure of 8.9 +/- 4.4 mm Hg was observed. In group B of 28 (41.8%) subjects fulfilling the criteria of postprandial hypotension systolic blood pressure decreased after the meal of 30.0 +/- 6.2 mm Hg, the difference between groups was statistically significant (p < 0.001). Autonomic cardiovascular neuropathy was recognized in 41 (61.2%) of the study patients. The more advanced neuropathy was stated in group B (neuropathy scale score: group A--1.54 +/- 1.48 points, group B--5.11 +/- 1.93 points, p < 0.001). Statistically significant correlation between the magnitude of postprandial systolic blood pressure fall and cardiovascular neuropathy scale score was noted (Spearman's correlation co-efficient R: -0.612: p < 0.01). Postprandial blood pressure fall correlated significantly with orthostatic systolic blood pressure changes (correlation co-efficient R: 0.610; p < 0.001). CONCLUSIONS: Postprandial hypotension is an important symptom of diabetic cardiovascular neuropathy. It is recommended to include postprandial blood pressure measurements in diagnostic algorithm of autonomic nervous system dysfunction in diabetic patients.

[Nonfunctional pituitary adenoma and pulmonary sarcoidosis--a case report].

A case of the coexistence of nonfunctional pituitary adenoma and pulmonary sarcoidosis is reported. 39 years old female presented symptoms of a pituitary-gonadal axis insufficiency, visual deficit and dizziness. CT pituitary imaging revealed large intra and extrasellar tumour. Histological examination of the tissue obtained at transsphenoidal surgery showed chromophobic adenoma. Hypopituitarism and transient diabetes insipidus occurred after the surgery. The adequate replacement therapy with hydrocortisone and sex steroids was introduced. At the time of the pituitary tumour diagnosis enlargement of pulmonary lymph nodes was also observed. Based on histological examination of tracheal and bronchial epithelium specimens obtained during bronchoscopy the diagnosis of pulmonary sarcoidosis was made. No other systemic sarcoidosis localisation was confirmed. Histological re-evaluation of adenoma showed no noncaseating granuloma tissue. The overlapping symptoms of pituitary adenoma and other intrasellar masses may result in diagnostic difficulties, particularly in the presence of systemic disorders in which this gland may be involved.
