Abstract
One of the most important benign tumors in neurofibromatosis type 1 (NF1) is plexiform neurofibroma, and there is a risk of developing malignant peripheral nerve sheath tumor (MPNST) throughout life approximately 10%. However lesion characterization by anatomical imaging methods are not possible. Because of that most of cases goes to biopsy. Using of fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) for lesion characterization can be helpful in NF1 patients. We aimed to present an example of the efficacy of FDG-PET/CT in distinguishing benign neurofibroma from MPNST. A 6-year-old male patient who had NF1 admitted to emergency service due to high fever. Acute upper respiratory tract infection was diagnosed; antipyretic and abundant fluid intake was suggested. When high fever continued, the patient referred to our hospital on detection of axillary lymphadenopathy. Leukocytosis was detected in patient's blood count. Sedimentation was 54 mm/h, C-reactive protein 166 g/L, and lactate dehydrogenase 276U/L. Blood and throat cultures did not show pathogenic bacteria. In serological tests, VZV-IgG, EBV-VCA-IgG, and CMV-IgG were avidite positive; Hepatitis B Ag, Anti-HIV, Anti-HAV IgG and IgM, Anti-HCV, EBV-VCA IgM, and VZV-IgM were negative. Based on these results, cervical and thoracic contrast-enhanced computed tomography was performed on preliminary diagnosis of MPNST. Solid lesions with rounded margins, large one being 49 mm in size, that extend from superior mediastinum to posterior mediastinum, left axillary region, and left part of neck were detected, and they were surrounding the vascular structures. Since neurofibroma, MPNST, and lymphoma could not be distinguished, patient referred to FDG-PET/CT scanning. In FDG-PET/CT, highest lesion maximum standardized uptake value (SUVmax) was 1.5; SUVmax lesion/SUVmax liver 1.0, and SUVmax/ SUV mean liver 1.5. Biopsy from mediastinal and axillary region did not have LN structure and was positive for S-100 immunostaining, and patient was diagnosed as benign neurofibroma. We believe that there is no need for biopsy in lesions considered benign based on FDG-PET/CT parameters.

Abstract
The lesion detection capability and clinical effectiveness of dual-head coincidence gamma camera imaging (c-PET) were compared with those of dedicated positron emission tomography (d-PET) in 37 cancer patients who underwent whole-body c-PET and d-PET imaging after administration of 370 − 540 MBq 18F-fluorodeoxyglucose. Eighty-nine lesions were detected on c-PET whereas 133 lesions were seen with d-PET imaging. The relative sensitivity of c-PET compared with d-PET was 62% and 73% for lesions < 15 and ≤ 15 mm, respectively, and the relative concordance rate was 84% when the patients were restaged. Since the lesion detection rate of c-PET imaging was lower than that of d-PET, the detection of small lesions, therefore, requires care. The clinical effectiveness of c-PET, however, was similar to that of d-PET and, therefore, it is concluded that c-PET can be used as an alternative to d-PET, particularly considering the high cost and limited availability of d-PET cameras.

Abstract
Gastric carcinoma is reported to be more frequent in geographical areas where diets are either iodine-deficient or iodine-excessive. Reports have also shown an association between thyroid diseases and some of the risk factors for gastric carcinoma. We investigated the frequency of thyroid disorders in 61 patients with gastric carcinoma compared with 55 healthy control subjects. Thyroid health was evaluated by physical examination and by measuring the serum levels of thyroid hormones and thyroid autoantibodies. More patients with gastric cancer had goitre compared with healthy controls (49.1% versus 20%, respectively). Significantly more patients with gastric cancer had non-toxic goitre compared with control subjects. There was also a significant difference in the incidence of autoimmune thyroid disease −27.8% of patients with gastric cancer versus 10.9% of control subjects were affected. These results indicate that there is a significant association between gastric cancer and thyroid disorders.

Abstract
AIM The aim was to evaluate the therapeutic effectiveness of granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood mononuclear cells (PBMNCs) in critical limb ischemia (CLI) of type 2 diabetic patients. METHOD Forty diabetic patients with CLI were enrolled and randomized to treatment and control groups. In the treatment group, the patients received subcutaneous injections of recombinant human G-CSF (30 MU/day) for 5 days to mobilize stem cells. PBMNCs were collected and transplanted by multiple intramuscular injections of 1 ml in 1-1.5-cm depth into ischemic limbs. RESULTS At the end of 12 weeks of follow-up, the baseline and end point results in transplant group were as follows: Fontaine score improved from 3.8±03 to 3±0.5 (P=.0001), ankle brachial pressure index increased from 0.68±0.24 to 0.87±024 (P=.001), transcutaneous oxygen increased from 33±14 mmHg to 44±10 mmHg (P=.0001), and 6-min walking distance improved from 280±82 m to 338±98 m (P=.0001). Pain score decreased from 8.2±1.3 to 5.63±1.6 (P=.001), and the number of patients with limb ulcers was reduced from 9/20 (45%) to 3/20 (15%) (P=.031). In the control group, Fontaine score, 6-min walking distance, and pain score were improved; ankle brachial pressure index and transcutaneous oxygen pressure were not improved. The number of patients with limb ulcers did not change in the control group. There are improvement in amputation rates, collateral vessel development, and number of limb ulcers healed. CONCLUSIONS These results indicate that the autologous transplantation of G-CSF that mobilized PBMNCs in CLI diabetic patients is safe and effective in patient compliant reduction and improved perfusion.

Abstract
A 15-year-old boy sustained a high-voltage electrical injury with full-thickness scalp and calvarial bone necrosis in the parieto-occipital region. While necrotic soft tissues were debrided on the fifth day of injury, the devitalized calvaria was preserved. Bilayered coverage of the necrotic bone was achieved by transposition of 'bipedicled pericranial flap' and 'bipedicled scalp flap'. No complication was observed in the postoperative period. A bone resorption area, smaller than the original necrotic bone area, was observed in the long-term follow-ups.

Abstract
OBJECTIVE We present a patient who developed visual loss after carbon monoxide (CO) poisoning and was treated with hyperbaric oxygen. CLINICAL PRESENTATION AND INTERVENTION A 21-year-old woman poisoned with CO (with coma lasting 4 h and carboxyhemoglobin level 46%) developed seizures and cortical blindness 3 days after poisoning. Four years later, her visual acuity was 0.2 in both eyes. An (18)F-fluorodeoxyglucose positron emission tomography (PET) scan showed reduced metabolism in the bilateral posterior temporal and occipital lobes. The patient received a total of 50 hyperbaric oxygen sessions over 3 months for visual loss and the visual acuity improved to 0.5 in both eyes. In addition, increased metabolism was detected in the brain in post-treatment PET scans. CONCLUSION PET documented brain hypoperfusion 4 years after CO poisoning and hyperbaric oxygen therapy improved visual acuity. However, we cannot endorse routine use of hyperbaric oxygen for such patients, until results of further clinical trials demonstrate efficacy of hyperbaric oxygen in CO-induced chronic brain injury.

Abstract
PURPOSE The aim of this study was to investigate the early effect of platelet-rich plasma (PRP) on osteoblastic activity during the healing process of soft tissue impacted mandibular third molar extraction sockets by means of bone scintigraphy. PATIENTS AND METHODS Twelve patients with bilaterally soft tissue impacted mandibular third molars were included in the study. The impacted right and left mandibular third molars were surgically extracted in the same session. PRP was administered randomly into the extraction sockets in the study (S) group whereas the extraction sockets in the control (C) group were left without PRP treatment. Scintigrams were obtained in the first and fourth weeks after surgery to evaluate the osteoblastic activity within extraction sockets in both groups. RESULTS Scintigraphic findings of postoperative first and fourth weeks did not show significantly increased osteoblastic activity between S group and C group (P > .05). However, the osteoblastic activity in both groups significantly increased in postoperative week 4 in comparison to week 1 (P < .05). CONCLUSION The application of PRP alone into soft tissue impacted mandibular third molar extraction sockets failed to increase the osteoblastic activity in postsurgical weeks 1 and 4 in comparison to non-PRP-treated sockets.

Abstract
A 53-year-old male patient was admitted to our hospital with abdominal pain in the right upper quadrant. There was no change in laboratory investigations other than a slight increase in serum levels of alkaline phosphatase (ALP), alanine aminotransferase (ALT), and gamma glutamyl transferase (GGT). Computed tomography (CT) of the abdomen showed multiple hepatic nodular lesions in the liver. Tru-cut biopsy of the lesions was reported as well-differentiated neuroendocrine carcinoma. The patient received sandostatin treatment. After a few days, the patient was hospitalized in the intensive care unit with disturbance of consciousness and clinical features suggestive of encephalopathy. Serum ammonia level was found highly elevated. After the treatment with L-ornithine-L-aspartate, a remarkable improvement in the level of patient's sensorium occurred as well as a reduction in serum ammonia level within a few days. Transarterial chemoembolization (TACE) was performed one week later. The patient's condition began to worsen along with increase in serum ammonia level and he died because of hyperammonemic encephalopathy. There are case reports of hyperammonemia with some malignancies such as multiple myeloma, plasma cell leukemia, and leiomyosarcoma, or in some patients who have received chemotherapy. This case may suggest an association between hyperammonemia and neuroendocrine tumors.

Abstract
It is being questioned if Helicobacter pylori infection, which causes a chronic inflammatory response, can increase the frequency and severity of attacks in patients with Familial Mediterranean Fever (FMF) and if the impact of inflammatory response can be diminished by eradication of the infection. To evaluate if there is difference in interleukin (IL)-6 levels of H. pylori-positive and -negative patients both before and during FMF attacks; if there is a change in IL-6 levels following successful eradication treatment; and if MEFV gene mutations have an effect on IL-6 levels. IL-6 levels were evaluated in 47 FMF patients before and during FMF attacks. Genetic testing to determine M694V, M694I, E148Q, V726V, M680I mutations was also performed in all patients. IL-6 levels were also determined after successful eradication of the infection in H. pylori-positive patients. IL-6 levels were compared in H. pylori-positive and -negative patients, and before and after eradication treatment in patients who cleared the infection. Number of patients in tested mutation groups was not enough to compare IL-6 levels in these groups. Thirty-four patients (73.9%) were H. pylori-positive. Before FMF attack there was no statistically significant difference in IL-6 levels of H. pylori-positive and -negative groups. IL-6 levels were significantly higher in both groups during the attacks than before the attacks (p < 0.05). There was a statistically significant decline in IL-6 levels both before and during FMF attacks, following eradication therapy in patients who cleared the infection (p < 0.05). In patients with homozygous M694V mutation, IL-6 levels before and during the FMF attacks were not significantly different in H. pylori-positive and -negative groups, despite a much lower level found in H. pylori-negative group (p > 0.05). Comparisons were not performed in other mutation groups because of small number of patients in each group. C-reactive protein (CRP) and fibrinogen levels were not significantly different between the groups (p > 0.05). We believe that the observation of IL-6 levels are lower both before and during FMF attacks both in H. pylori-negative patients and in patients who cleared the infection after eradication therapy is very important in the determination of the role of eradication of H. pylori on decreasing the frequency and severity of FMF attacks. As for today, the correlation between H. pylori infection and FMF seems unlikely; however, studies evaluating the interaction of cytokines in both diseases and their relations and roles will be needed to reach better conclusions.

Abstract
During acute ischaemia the N-terminal site of albumin is altered, reducing its binding capacity; the modified protein is termed ischaemia-modified albumin (IMA). IMA is a sensitive marker of acute myocardial ischaemia but its diagnostic value in chronic angina pectoris patients is unclear. We investigated changes in blood levels of IMA during myocardial perfusion scintigraphy in patients with chronic angina pectoris in a study including 26 male and 20 female patients, with mean age 60 years. Technetium 99m perfusion imaging detected myocardial ischaemia in 26 patients. Coronary angiography was carried out in these 26 ischaemic patients. Mean IMA values at rest and peak exercise were significantly higher in the ischaemic than the nonischaemic group. All IMA values were considered negative for cardiac ischaemia. Peak exercise IMA was significantly lower than the pre-exercise level only in the non-ischaemic group. IMA measurements during myocardial perfusion scintigraphy are not helpful in the diagnosis of myocardial ischaemia in patients with stable angina pectoris.

Abstract
We assessed the diagnostic value of the 14C urea breath test (UBT) in the detection of Helicobacter pylori compared with histology and the rapid urease test (RUT). The study included 68 patients (22 men and 46 women) with dyspeptic symptoms. H. pylori status was evaluated by 14C UBT, RUT and histology. Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy were determined for 14C UBT and for RUT. Histology revealed dense yeast-like micro-organisms in the biopsy specimens in all patients with false-positive results by 14C UBT (n = 8), a significantly higher proportion than in patients with negative 14C UBT (five of 31). The low specificity of the H. pylori 14C UBT should not be neglected by accepting histology results as false-negative. Gastric mucosal colonization by yeast-like micro-organisms with urease activity can account for the high frequency of false-positive results for 14C UBT.

Abstract
AIM We hypothesised that serum calcium (Ca) and parathormone (PTH) levels correlate with radiological extent and that there may also be a relationship between the tuberculin skin test (TST), serum Ca and PTH levels in patients with pulmonary tuberculosis (PTB). MATERIALS AND METHODS Forty-four patients with active PTB and 33 healthy subjects were enrolled in the study. Serum Ca, PTH, magnesium and phosphate levels were measured in patients and controls and compared. Correlations were also investigated for TST values, erythrocyte sedimentation rate (ESR), the degree of radiological involvement, serum PTH and corrected Ca levels. RESULTS There was a significant difference between the two groups for mean serum PTH and corrected Ca levels. Significant correlations were detected between radiological extent of disease and serum PTH levels, between TST values and serum PTH levels and between ESR and serum PTH levels. We suggest that abnormal Ca metabolism in PTB patients is related to the radiological extent of disease. Factors determining the radiological extent of disease, predominantly the patient's immune status, may have an important role in modulating Ca metabolism in PTB patients.

Abstract
INTRODUCTION Patients with ureteropelvic junction obstruction occasionally remain undiagnosed until adulthood. There are no objective criteria to predict the results of pyeloplasty in adult patients. We have evaluated the results of pyeloplasty in adult patients and investigated whether these results are correlated with the histopathology of the surgical specimen. MATERIALS AND METHODS Histological sections from 26 patients with ureteropelvic junction obstruction were analyzed. Their mean age was 25.1 years. Diethylenetriamine-pentaacetic acid scans were used to determine the degree of renal obstruction and postoperative healing. Improvement in diuretic renography was defined as a greater than 20% decrease in the half-time of the preoperative value. To examine smooth muscle and collagen tissue, sections were stained using Masson's trichrome. Smooth muscle ratio was identified by color image analysis. RESULTS 18 patients (69.2%) fulfilled the criteria of healing. Patients with an improved scan had a mean smooth muscle percent (SMP) of 1.85+/-0.87 while subjects with no significant change in their diuretic scans had a mean SMP of 0.36+/-0.03 (p=0.001). There was a strong correlation between the SMP and the improvement. CONCLUSIONS Adult pyeloplasty was found successful in about 70% of the cases. The SMP of the renal pelvis seems to be helpful in predicting the surgical outcome.

Abstract
In the last decade, studies were first done to determine the frequency of Gsalpha and later thyrotropin receptor (TSHR) mutations in benign autonomously functioning thyroid nodules (AFTN). Different frequencies ranging from 0% to 38% for GSp mutations and from 20% to 86% for TSHR mutations were found. There were only some limited case reports related to TSHR genetic alterations in malignant AFTN. Their role in autonomously functioning thyroid carcinomas is not well established. We present a patient who had thyroidectomy for toxic multinodular goiter and a papillary carcinoma was demonstrated histopathologically. Genomic DNA was isolated from two solid areas in the hot nodule and peripheral leukocytes of the patient. After amplifying the related regions, TSHR and GSalpha genes were analyzed by single-strand conformation polymorphism (SSCP) analysis. The precise localization of the mutations was identified by automatic DNA sequence analysis. An activating mutation of the TSHR gene (Leu 512 Arg) was found in the autonomously functioning papillary carcinoma. It is believed that this mutation causes constitutive activation of the cyclic adenosine monophosphate (cAMP) signal transduction pathway and thereby causes thyrotoxicosis and a hot thyroid nodule in an autonomously functioning papillary carcinoma.

Abstract
OBJECTIVE Idiopathic slow-transit constipation (STC) has been suggested to be a pangastrointestinal motility disorder. We investigated scintigraphically whether motility in the gallbladder and stomach was impaired in slow-transit constipation. METHODS Twenty-four patients with STC were studied. Colon transit time, gallbladder motility, and solid-phase gastric emptying were measured by scintigraphy. RESULTS Gallbladder dysmotility was observed in 8 of 18 (44.4%) patients. Mean gallbladder ejection fraction was 41.6 +/- 13.6% (range, 16.3-67.0%). Gastric emptying was delayed in 9 of 18 (50%) patients. Mean solid-phase gastric half-emptying time was 75 minutes. STC may be associated with impaired function of other gastrointestinal organs. Approximately half of patients with STC presented gallbladder or gastric dysmotility. CONCLUSION STC may not be a pure colonic abnormality; it may be a component of a pangastrointestinal tract motility disorder involving several organs.

Abstract
<i>Introduction:</i> We evaluated the role of the seminal plasma PSA level in the prediction of the response to α-blocker treatment in patients with benign prostatic hyperplasia. <i>Materials and Methods:</i> 18 male patients with lower urinary tract symptoms were enrolled in the study. After their blood was sampled for PSA, ejaculates of all the subjects were obtained. Serum and seminal plasma PSA levels were calculated by Active PSA IRMA kit. Patients were given 4 mg/day doxazosin for a period of 6 weeks, following which their International Prostate Symptom Score (IPSS) evaluation was repeated. The correlation between serum PSA, seminal plasma PSA and PSA density levels and the percentage improvement in IPSS was investigated. <i>Results:</i> The mean serum PSA level, the mean PSA density and the mean seminal PSA level of the patients were 2.7 ± 1.2 ng/ml, 0.05 ± 0.02 ng/ml/cm<sup>3</sup> and 0.7 ± 0.39 g/l, respectively. The percentage improvement in IPSS varied from 26.9 to 53.5%. Serum PSA and serum PSA density were not useful in the prediction of the response to α-blocker treatment, but the seminal PSA levels correlated with the percentage improvement in the IPSS (p = 0.017). <i>Conclusions:</i> Seminal plasma PSA has been found to be a better predictor of the response to α-blocker treatment when compared to serum PSA and PSA density.

Abstract
AIMS Regional changes in cerebral blood flow in patients with chronic hepatitis, cirrhosis and subclinical hepatic encephalopathy were investigated in the present study using single photon emission computed tomography (SPECT). METHODS Twenty patients with cirrhosis, 11 patients with chronic hepatitis, and nine healthy controls were included in the study. Cerebral SPECT were obtained for all patients. The percentages of cerebral blood flow of 14 regions to the cerebellar blood flow were determined. Only the patients with cirrhosis underwent psychometric evaluation: visual evoked potentials (VEP) measurements and electroencephalogram (EEG) recordings along with blood levels of albumin, bilirubin, and ammonia were measured and prothrombin time was determined in cirrhotic patients. These patients were classified according to the Child-Pugh classification. RESULTS Among cirrhotic patients, six had abnormal results in VEP studies, 11 in psychometric tests and with six in EEG evaluation. Any abnormality in psychometric tests and/or VEP studies is taken as the main criterion; subclinical hepatic encephalopathy was detected in 12 of 20 patients. According to SPECT results in patients with subclinical encephalopathy, a statistically significant decrease in cerebral blood flow in right thalamus and nearly significant decrease in left thalamus were observed. Regional blood flow was significantly higher in the frontal lobes of patients with cirrhosis when compared with healthy controls. Similarly, cerebral blood flow in frontal and cingulate regions was significantly higher in patients with chronic hepatitis than in healthy controls. There was no relationship between cerebral blood flow and blood levels of ammonia or Child-Pugh score, in cirrhotic patients. CONCLUSION Significant changes in cerebral blood flow may be present in chronic liver diseases and the authors suggest that the measurement of changes in cerebral blood flow might be useful in detecting subclinical hepatic encephalopathy.

Abstract
OBJECTIVES We evaluated the effects of ostioplasty and nasoantral window opening techniques employed in endoscopic surgery procedures for maxillary sinuses on mucociliary activity in rabbits. STUDY DESIGN The study included 15 adult male New Zealand white rabbits (mean weight 3.5 kg). The animals were divided into three groups equal in number. Following a vertical incision in the midline, one group underwent ostioplasty to widen the natural ostium of the maxillary sinus; a new nasoantral window was opened in another group; the other group (controls) underwent only sinus exploration. Thirty days after surgery, mucociliary activity of the maxillary sinuses was evaluated scintigraphically. RESULTS Compared with the control group, mucociliary activity decreased significantly in both groups, showing a higher deterioration with the nasoantral window opening technique (p<0.001) than that with the ostioplasty technique (p<0.05). CONCLUSION Since both techniques have adverse effects on the mucociliary activity of the maxillary sinuses, ostioplasty and nasoantral window opening techniques should be reserved for patients in whom they are uniquely required.

Abstract
Splenosis is heterotopic autotransplantation and seeding of splenic tissue. In the literature, only a few cases of splenosis involving the liver and the radiologic characteristics of these lesions have been reported. We report a case of intrahepatic splenosis diagnosed by ultrasound, computed tomography, magnetic resonance imaging and scintigraphic features. To our knowledge, our patient is the first case diagnosed only by radiologic and radionuclide examination without any intervention.

Abstract
The main goals of the clinical use of tumor markers are to evaluate the adequacy of the treatment, monitor recurrence and follow up response to the treatment applied. For this purpose a baseline level for the commonly used tumor marker must be known at the time of initial diagnosis, before any therapy, in order to compare with the tumor marker levels which will be obtained after the treatment and during the clinical follow-up. The aim of this study was to investigate the correlation, if there is any, of the baseline levels of CA15-3, CEA and prolactin (PRL) in patients with breast cancer with the most commonly used prognostic factors, i) the presence of distant metastasis, ii) the presence of axillary lymphatic invasion, iii) the number of invaded axillary lymph nodes, iv) tumor size and v) stage of the disease, for breast cancer. Baseline serum CA15-3, CEA and PRL levels of 172 patients with breast masses were determined prior to biopsy. The sensitivity and specificity of baseline CA15-3, CEA and PRL were; 23.2% and 95.3%, 17.41% and 83.7%, 5.8% and 97.6%, respectively. At least one of the three tumor markers was high in 36% (31/86) of the breast cancer patients. Baseline CA15-3 levels were frequently higher than CEA in patients with bone metastasis (60% vs. 20%) and axillary lymphatic invasion (31.8% vs. 25%), and showed a better correlation with the stage of disease. Baseline tumor marker levels showed no statistically significant correlation with either the number of invaded axillary lymph nodes or tumor size. In conclusion, sensitivities and negative predictive values for baseline CA15-3, CEA and PRL were not satisfactory for primary diagnosis of breast cancer. Correlation of baseline CA15-3 was found superior to CEA and PRL in terms of stage of disease, presence of axillary invasion and distant metastasis.

Abstract
The aim of this prospective study was to determine the diagnostic value of Tc-99m MDP scintimammography (SMG) for the detection of breast cancer in patients with breast masses and to compare the results with Tc-99m MIBI scintimammography. Twenty patients, categorized as suspicious, positive or benign for breast cancer according to the mammographic findings were included in the study. Dual phase Tc-99m MIBI and Tc-99m MDP SMG were performed in the prone lateral position within 5 days of each other. Although early and late Tc-99m MIBI SMG showed equal (90.4%) sensitivity, the specificity of late Tc-99m MIBI (87.5%) was found superior to early (62.5%) imaging. The overall sensitivity and specificity of early Tc-99m MDP SMG were 71.4% and 62.5%, respectively. Although late Tc-99m MDP imaging showed 100% specificity, its sensitivity was only 23.8%. In the patients with palpable masses, both early Tc-99m MDP and Tc-99m MIBI showed equal sensitivity (100%), but the sensitivity of early Tc-99m MIBI (37.5%) was found slightly higher than Tc-99m MDP (25.0%) for nonpalpable breast lesions. The sensitivity of Tc-99m MIBI and Tc-99m MDP SMG in detecting metastatic axillary involvement was 66.6% and 50%, respectively. High sensitivity and specificity together with its low cost, easy availability and the possibility of detecting bone metastases seems to make Tc-99m MDP a contributive agent in the evaluation of breast lesions as an alternative to Tc-99m MIBI.

Abstract
The study was designed to investigate the effect of trimebutine maleate, a drug used in both hyperkinetic and hypokinetic motility disorders, on gastric emptying in patients with non-ulcer dyspepsia having prolonged gastric emptying rates and to compare the parameters used for the determination of the lag period observed during the emptying of solid foods from the stomach. Gastric emptying was measured by the radionuclide technique. Twenty normal volunteers and 43 patients with non-ulcer dyspepsia participated in the study. Radionuclide imaging was performed by using a solid meal labeled with 99mTc-tin colloid. Of the patients with non-ulcer dyspepsia, 20 had prolonged gastric emptying. They were given three weeks of oral treatment with trimebutine maleate and had their radionuclide gastric emptying study repeated. Treatment with trimebutine maleate resulted in reduction in duration of the lag period and less retention of food at 100 minutes (p < 0.0005). After treatment with trimebutine maleate, no significant difference has been observed in the mean symptom score of patients with prolonged gastric emptying. Among the parameters used for the determination of the lag period, lag period determined by a mathematical equation (TLAG) has been found to be longer than the lag period determined by visual inspection of the images (VLAG) and there was correlation between the two parameters when the lag time was short.

Abstract
UNLABELLED Bone mineralization of healthy preterm infants fed human milk were compared with that of similar fed preterm formula. Bone mineralization was studied by dual energy X-ray absorptiometry in 43 preterm infants divided into two groups; 21 preterm infants were fed with maternal breast milk and 22 preterm infants with a preterm formula containing 70 mg calcium and 35 mg phosphorus per decilitre. CONCLUSION Preterm infants fed breast milk had lower bone mineral density than the preterm formula-fed group. Fortifying preterm human milk with calcium and phosphorus will improve bone mineralization in preterm infants.

Abstract
We present a 32-year-old male with a thyrotropin (TSH)-secreting pituitary microadenoma with normal alpha-subunit (SU) and/or alpha-SU/TSH molar ratio. An interesting feature of this patient is that the size of the pituitary tumor remained unchanged during a 6-year follow-up without treatment. The tumor was clearly visualized with somatostatin receptor imaging, indicating that it was somatostatin receptor-positive. Subcutaneous injection of 100 microg octreotide acetate three times daily resulted in significant reduction of TSH and free thyroid hormones 6 weeks after initiation of treatment. However, tumor size was not changed 3 months after initiation of octreotide therapy and thyroid hormones, but not TSH level, eventually increased in spite of increasing the octreotide dosage up to 600 microg/day. This led to discontinuation of treatment. The patient responded only temporarily to octreotide in spite of somatostatin receptors. This case further demonstrates that a normal alpha-SU and/or alpha-SU/TSH molar ratio cannot exclude the possibility of a TSH-secreting pituitary adenoma.

Abstract
In-111 labeled pentetreotide scintigraphy was applied to three patients with proven granulomatous disease (two with sarcoidosis, one with tuberculosis). All revealed accumulation of In-111 labeled pentetreotide in the granulomatous lesions, which was considered to be due to the presence of activated lymphocytes in these regions. This method may be of value in assessing the activity and extent of sarcoidosis and tuberculosis.
