RESUMO

Racecadotril, used as an antidiarrheal drug in humans and some animals such as the dog, inhibits peripheral enkephalinase, which degrades enkephalins and enkephalinase inhibition induces a selective increase in chloride absorption from the intestines. The study material consisted of 46 calves with infectious diarrhea and 14 healthy calves in the age 2-20 days. The calves were divided into eight groups; healthy calves (HG), healthy calves administered racecadotril (HRG), calves with E.coli-associated diarrhea (ECG), calves with E.coli-associated diarrhea administered racecadotril (ECRG), calves with bovine Rotavirus/Coronavirus-associated diarrhea (VG), calves with bovine Rotavirus/Coronavirus-associated diarrhea administered racecadotril (VRG), calves with C. parvum-associated diarrhea (CG) and calves with C. parvum-associated diarrhea administered racecadotril (CRG). Calves in the racecadotril groups received oral racecadotril at a dose of 2.5 mg/kg twice a day for 3 days. A routine clinical examination of all calves was performed. Hemogram and blood gas measurements were made from the blood samples. Standard diarrhea treatment was applied to the HG, ECG, CG, and VG groups. Clinical score parameters such as appetite, feces quality, dehydration, standing and death and some blood gas and hemogram parameters were evaluated to determine the clinical efficacy of racecadotril. Clinical score parameters were determined observationally. Blood gas measurements were performed using a blood gas analyzer. The hemogram was performed using an automated hematologic analyzer. Statistically significant differences were determined in the blood pH, bicarbonate, base deficit, lactate, and total leukocyte count in calves with diarrhea compared to healthy calves. After the treatments, these parameters were found to be within normal limits. At the end of treatment, 42 of the 46 diarrheal calves recovered, while 4 died. We found that racecadotril was effective in improving both clinical recovery and feces consistency in neonatal calves with diarrhea caused by E. coli. As a result, it can be stated that racecadotril, which has an antisecretory effect, is beneficial in the treatment of bacterial diarrhea caused by such as E. coli.

RESUMO

The aim of this study was to investigate the cardiotoxic effect of the combination of tilmicosin and diclofenac sodium in sheep. Thirty-two sheep were used and were randomly divided into four equal groups as tilmicosin (T), diclofenac sodium (D), tilmicosin+diclofenac sodium (TD) and control (C) group. Group T received a single dose of tilmicosin, Group D was administered diclofenac sodium once a day for 3 days, and group TD was administered diclofenac and tilmicosin at the same doses as group T and D. Group C received NaCl in a similar way. The blood samples were taken before dosing and at 4th, 8th, 24th and 72nd hour post-dosing for measurement of cardiac markers such as H-FABP, cTn-I, CK-MB. H-FABP level of group TD was found to be significantly (p⟨0.05) higher than of group C at the 8th, 24th and 72nd hour and group D and T at the 72nd hour. cTn-I and CK-MB levels of group TD were found significantly (p⟨0.05) higher compared with other groups. In conclusion, the combined use of tilmicosin and diclofenac in sheep causes an increase in cardiac biomarkers and it can be stated that this combination of drugs may cause cardiac damage.

RESUMO

Rhabdomyolysis is a syndrome of rapid skeletal muscle breakdown as a result of direct or indirect skeletal muscle injury. An important cause of rhabdomyolysis is the use of hard drugs among which cocaine but also different psychotropic drugs are associated with the development of rhabdomyolysis. The clinical presentation of rhabdomyolysis is diverse and the course can be relatively harmless but also potentially life threatening. Therefore, it is important to recognize rhabdomyolysis in an early stage in order to initiate treatment in a timely manner. We describe a 40-year-old man with schizophrenia who developed rhabdomyolysis after the use of cocaine.

RESUMO

Context: 18F-fluorocholine (FCH) has been used as a positron emission tomography (PET) tracer in the localization of hyper-functioning parathyroid glands (HPGs). Objective: We performed this methodological study to evaluate the diagnostic performance of 18F-FCH PET/computerized tomography (CT) and repeated ultrasonography (USG) in detecting unidentified lesions in patients with primary hyperparathyroidism (PHPT). Design: In this retrospective methodological study, we studied the diagnostic performance of 18F-FCH PET/CT and a repeated USG in detecting unidentified parathyroid lesions. Subjects and Methods: Twenty-eight patients who were diagnosed with PHPT, had an indication for surgery following the current guidelines and had no identified lesion on 99mTc-MIBI SPECT/CT, USG, or other imaging methods than 18F-FCH PET/CT, included in the study. Results: While lesions were detected in 26 patients via 18F-FCH PET/CT among 28 patients [92.9% (95% CI: 76.6%-99.1%)], the lesion detection rate was 95.7% (95% CI: 78.1%-99.9%) in 23 patients who underwent a repeated USG. The sensitivity and the accuracy of both 18F-FCH PET/CT and repeated USG were 95.2% (95% CI: 76.2%-99.9%) and 95.0 (95% CI: 75.1%-99.9%), respectively. Conclusions: This study supports that the combination of 18F-FCH PET/CT and repeated USG has promising potential for being an imaging technique for early detection and localization of HPGs.

RESUMO

This study aimed to assess the clinical efficacy of pentoxifylline (PTX) and L-glutamine (L-Gln) treatment on ischemia and reperfusion (I/R) injury in the abomasal tissue, acute phase response (APR), oxidative stress (OS), cytokine response, hemostatic, and coagulation disorders in the 96-h period before and after surgery in displaced abomasum (DA) cases. The study sample consisted of 48 dairy cows with DA that were categorized into four groups as group S (Sham group) (9 Left displaced abomasum (LDA)+3 Right displaced abomasum (RDA), group P (PTX) (10 LDA+2 RDA), group G (L-Gln) (10 LDA+2 RDA), and group P+G (PTX+L-Gln) (10 LDA+2 RDA). Acute-phase protein (Haptoglobin), oxidative stress indicators (malondialdehyde, nitric oxide, and glutathione), cytokines (tumor necrosis factor (TNF)-α and interleukin-1ß (IL-1ß), coagulation factors (D-Dimer, Antithrombin (ATIII), Thrombin-antithrombin complex, Plasminogen activator inhibitor-1), and enzyme activities (lactate dehydrogenase, gamma- -glutamyl transferase, sorbitol dehydrogenase, glutamate dehydrogenase, adenosine deaminase, myeloperoxidase, and creatine phosphokinase) in blood serum samples and coagulometric analyses of blood plasma were performed in samples taken before the operation and at 30 and 60 min and 2, 5, 10, 24, 48, 72, and 96 h after the operation. In DA cases, while post-operative treatment procedures with PTX and L-Gln were effective in decreasing APR and OS, these were ineffective in prohibiting the inflammatory response coordinated by cytokines. For the treatment and prevention of I/R injury in the DA cases, PTX and L-Gln procedures hold promise with their effects on APR, OS, and hemostatic dysfunction. Additional treatment procedures are required for the suppression of inflammatory response, and the effectiveness of preconditioning treatment may be evaluated.

RESUMO

The aim of this study was to evaluate the intestinal and cardiac biomarkers in the determination of intestinal and cardiac damage in dogs with parvoviral enteritis. The material of this study consisted of 10 healthy dogs (control group) and 30 dogs with parvoviral enteritis (experimental group) admitted to the Department of Internal Medicine, Faculty of Veterinary Medicine, Selcuk University.Serum samples were extracted from the collected blood samples taken from vena cephalicavenipuncture for analysis of blood gases, haemogram and to measure the levels of intestinal-fatty acid-binding protein (I-FABP), trefoil factor 3 (TFF-3), claudin-3 (CLDN-3), heart-type fatty acid-binding protein (H-FABP), cardiac troponin I (cTnI), and creatine kinase-myocardial band (CK-MB) by enzyme linked immunosorbent assay (ELISA) test kits. Statistically significant decreases in the blood gas hydrogen ion concentration (pH), partial pressure of oxygen (pO2), sodium (Na), bicarbonate (HCO3), and oxygen saturation (SatO2) levels and significant increase in the levels of I-FABP, TFF-3, CK-MB, cTnI and also in the haemogram, a decrease in leukocyte (WBC) level and an increase in platelet (THR) level were detected in parvoviral dogs compared to the control group (p⟨0.05). Also ROC analysis revealed on 0th hour for the utility of I-FABP and on 48th hour for TFF-3 in differentiating in the experimental group between the survivor and non-survivor dogs. Other intestinal-related biomarker (CLDN-3) and none of the cardiac-related biomarkers (H-FABP, CK-MB and cTnI) are not high enough for prediction of mortality.In conclusion, it was determined that I-FABP and TFF-3 for the intestinal injury and morta-lity prediction, and CK-MB and cTnI for the cardiac injury were useful and reliable biomarkers to determine the damage caused by parvovirus in dogs.

RESUMO

The aim of this study was to compare effect of combinations of intravenous isotonic sodium bicarbonate (NaHCO3), acetate Ringer, lactate Ringer and small-volume hypertonic sodium chloride (NaCI) solutions along with oral electrolyte solutions (OES) on the treatment of neonatal calf diarrhea with moderate dehydration and metabolic acidosis. Thirty-two calves with diarrhea were used in the study. Calves were randomly assigned to receive acetate Ringer solution (n=8), lactate Ringer solution (n=8), isotonic NaHCO3 (n=8) and 7.2% saline solutions (n=8), and two liters of OES were administrated to all calves orally at the end of intravenous administration. Blood samples for blood gas and biochemical analyses were collected at 0 hours and at 0.5, 1, 2, 4, 6 and 24 hours intervals. All the calves had mild to moderate metabolic acidosis on admission. Increased plasma volume and sodium concentration, but decreased serum total protein were observed within 0.5 hours following administration of hypertonic 7.2% NaCI + OES, compared to other 3 groups. In conclusion, administration of intravenous hypertonic 7.2% NaCI solution in small volume along with OES provided fast and effective improvement of dehydration and acid-base abnormalities within short time in treatment of calf diarrhea with moderate dehydration and metabolic acidosis.

RESUMO

Disseminated intravascular coagulation (DIC) is a complex, dynamic and hemostatic disorder which develops secondarily to a disease characterized with an imbalance in the pro-coagulant and anti-coagulant components of hemostasis. The aim of the study is to evaluate hemostatic dysfunc- tion and the DIC syndrome in cattle with displaced abomasum (DA), with using the hematologic analyses and an extensive coagulation profile in the 96 hour-period including before and after surgery. The animal material of the study consisted of 12 dairy cows diagnosed with displaced abomasum (9 LDA and 3 RDA without volvulus) in the 2-4 week period after parturation and with no other post-partum disease. In dairy cows diagnosed with DA, hematological, coagulomet- ric (PT, APTT, Fibrinogen) and coagulation factor analyses [D-Dimer, TAT (thrombin-anti- thrombin complex), ATIII (antithrombin III), PAI-1 (plazminogen activator inhibitor-1] were performed in blood samples obtained before the operation as well as 30 minutes, 60 minutes and 2, 5, 10, 24, 48, 72 and 96 hours after the operation. In the DA cases, abnormalities were found in 6 of the 8 coagulation parameters. In the LDA and RDA groups, prolonged PT (sec), PT (INR) and APTT, hypofibrinogenemia, an increase in serum D-Dimer concentration at 72 and 96 hours after the operation and an increase in serum ATIII concentrations before and 30, 60 minutes and 2, 5, 72 and 96 hours after the operation was found (p⟨0.05). Hemostatic dysfunction and the risk of DIC developing in DA cases and continuing in the post-operative period was determined.

RESUMO

Hyperlactatemia, hypercapnia, low pH and low oxygen saturation (SatO2) are commonly observed in premature calves. These clinical indicators are associated with increased mortality in preterm human newborns with respiratory distress syndrome (RDS). The aim of this study was to investigate the prognostic importance of venous pH, partial pressure of carbon dioxide (pCO2) and lactate level and which parameters are related with mortality in premature calves with RDS. All premature calves (52 male/58 female) were admitted to clinic within 12-24 hours after birth and blood samples were also taken into heparinised plastic syringes from the jugular vein within 30 minutes following admission. Diagnosis of RDS was made by both clinical signs and blood gas results. For the evaluation of independent samples, t test was used to compare the venous blood gas indicators of surviving and non-surviving premature calves. Receiver operating characteristics curves were used to determine a cut-off value in terms of lactate and pCO2 measurements among non-surviving and surviving calves. Venous pH, pCO2, SatO2, base deficit, bicarbonate (HCO3) and lactate levels showed a significant variance between surviving and non-surviving calves. Mean venous pH, pCO2, SatO2, lactate levels in non-surviving premature calves was 7.05, 78.9 mm Hg, 16.1 per cent and 9.50 mmol/l, respectively. Mean pH, pCO2, SatO2 and lactate levels in surviving premature calves were 7.29, 56.3 mm Hg, 25.5 per cent and 5.1 mmol/l, respectively. The cut-off values for lactate and pCO2 were 7.5 mmol/l and 63.5 mm Hg, respectively. In conclusion, the results of the study show that venous blood lactate and pCO2 have prognostic importance in premature calves with RDS.

RESUMO

PURPOSE: Familial neurohypophyseal diabetes insipidus (FNDI) is a rare, autosomal dominant, inherited disorder which is characterized by severe polydipsia and polyuria generally presenting in early childhood. In the present study, we aimed to analyze the AVP gene in a Turkish family with FNDI. METHODS: Four patients with neurohypophyseal diabetes insipidus and ten healthy members of the family were studied. Diabetes insipidus was diagnosed by the water deprivation test in affected family members. Mutation analysis was performed by sequencing the whole coding region of AVP-NPII gene using DNA isolated from peripheral blood samples. RESULTS: Urine osmolality was low (<300 mOsm/kg) during water deprivation test, and an increase more than 50 % in urine osmolality and recovery of the symptoms were observed by the administration of desmopressin in all patients. Plasma copeptin levels were lower than expected according to plasma osmolality. Pituitary MRI revealed partial empty sella with a bright spot in index patient and a normal neurohypophysis in the other affected subjects. Genetic screening revealed a novel, heterozygous mutation designated as c.-3A>C in all patients. CONCLUSION: c.-3A>C mutation in 5'UTR of AVP gene in this family might lead to the truncation of signal peptide, aggregation of AVP in the cytoplasm instead of targeting in the endoplasmic reticulum, thereby could disrupt AVP secretion without causing neuronal cytotoxicity, which might explain the presence of bright spot. The predicted effect of this mutation should be investigated by further in vitro molecular studies.

RESUMO

INTRODUCTION: Haemorrhage from the injured extremity is a significant cause of preventable death in military settings. This study evaluated the effect of training on the efficacy of the combat application tourniquet (CAT) and to define standards for military personnel. METHOD: Participants from a training tank battalion were randomised. Data collected included age, body mass index, mean arterial pressure, hand dominance, femoral artery diameter and skin thickness. The study involved tourniquet application times (AT) and application success rates in basic, after-training and eyes-closed phases. Doppler ultrasound was used to identify the presence or absence of popliteal, radial and ulnar artery pulses. RESULTS: A total of 102 trainees participated. In the after-training phase, the left and right upper extremity ATs were 35 ± 13.1 s, and 34.8 ± 13.5 s and the right and left lower extremity ATs were 20.6 ± 6.0 s and 20.5 ± 5.5 s, respectively. The overall tourniquet success rates in three successive study phases were 69.6%, 82.4% and 91.2%, respectively. A negative significant relationship was found between extremity circumference and tourniquet success. DISCUSSION: The results show that the efficacy of CAT application increases with training. Further studies are required to investigate the reasons underlying application failures. This single group prospective randomised study involves level of evidence 4.

RESUMO

The aim of the present study was to assess metabolic changes occurring in Holstein cows with left or right abomasal displacement. Total sialic acid (TSA) values of the left abomasal displacement (LDA) group were elevated significantly (p < 0.0001) as compared to the controls. In the LDA group, serum ceruloplasmin (CPN) and aspartate transaminase (AST) levels were increased significantly (p < 0.0001) as well. Compared to the control group, serum glutathione (GSH) level was decreased significantly in both LDA and right abomasal displacement (RDA) groups (p < 0.0001). Among the clinical examination parameters, rumen contraction rates were decreased in both LDA and RDA groups significantly (p < 0.0001). These results suggest that inflammatory and oxidative parameters might have taken part in the pathogenesis of abomasal displacement. In this regard, anti-cytokine and anti-oxidant therapies developed in human medicine may also play a potential therapeutic role in the fatty liver and abomasal displacement in cattle.

RESUMO

PURPOSE: The majority of patients with pancreatic cancer present with advanced disease. Systemic chemotherapy for patients with pancreatic cancer has limited impact on overall survival (OS). Patients eligible for chemotherapy should be selected carefully. The aim of this study was to analyse prognostic factors for OS in advanced pancreatic cancer patients treated with first-line palliative chemotherapy with gemcitabine alone or gemcitabine plus cisplatin. METHODS: We retrospectively reviewed 343 locally advanced or metastatic pancreatic cancer patients who were treated with gemcitabine or gemcitabine plus cisplatin as first-line chemotherapy between December 2000 and June 2011. Fifteen potential prognostic variables were chosen for analysis. Univariate and multivariate analyses were conducted to identify prognostic factors associated with OS. Univariate and multivariate statistical methods were used to determine prognostic factors. RESULTS: Among the 15 variables of univariate analysis, 6 were identified to have prognostic significance: stage (p<0.001), cholestasis (p=0.02), weight loss, prior pancreatectomy, serum CEA level (p<0.001) and serum CA19-9 level (p>0.001). In addition, age, chemotherapy and liver metastasis were of borderline significance (p=0.06). Multivariate analysis (Cox proportional hazard model) included the 6 significant prognostic factors of univariate analysis and showed that stage was independent prognostic factor for OS, as were weight loss, and serum CEA level. CONCLUSION: Stage, weight loss, and serum CEA level were identified as important prognostic factors for OS in advanced pancreatic cancer patients. These findings may also facilitate pretreatment prediction of OS and can be used for selecting patients for treatment.

RESUMO

The majority of patients with pancreatic cancer is of advanced disease. Several randomized Phase II and III trials suggest that the combination of gemcitabine and cisplatin (GemCis) response rates were higher than Gemcitabine (Gem) alone, however the trials were not enough powered to indicate a statistically significant prolongation of survival in patients with advanced pancreatic adenocarcinoma. The aim of this retrospective multicenter study is to evaluated the efficiency of Gem alone versus GemCis in patients with locally advanced and/or metastatic pancreatic adenocarcinoma .A total of 406 patients, from fourteen centers were evaluated retrospectively. All patients received Gem or GemCis as first-line treatment between September 2005 to March 2011. Primary end of this study were to evaluate the toxicity, clinical response rate, progression-free survival (PFS) and overall survival (OS) between the arms. There were 156 patients (M: 98, F: 58) in Gem arm and 250 patients (M: 175, F: 75) in the combination arm. Gemcitabin arm patients older than the combination arm ( median 63 vs 57.5, p=0.001). In patients with the combination arm had a higher dose reduction (25.2% vs 11.3%, p=0.001) and dose delay (34% vs 16.8%, p=0.001). Among patients with the combination and Gemcitabin arm gender, diabetes mellitus, performance status, cholestasis, grade, stage did not have a statistically difference (p>0.05). Clinical response rate to the combination arm was higher than the Gem arm (69.0% vs 49.7%, p=0.001). PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance (8.9 vs 6.0, p=0.08). OS was not significantly superior in the GemCis arm (12.0 vs 10.2, p>0.05). Grade III-IV hematologic and nonhematologic toxicity were higher in the combination arm. PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance. OS was not significantly superior in the GemCis arm.

RESUMO

PURPOSE: Hypoxia is common in many solid tumors such as breast, head-neck, and soft tissue malignancies. Hypoxia causes overexpression of hypoxia inducible factor-1 alpha (HIF-1α) and carbonic anhydrase IX (CA IX) which are associated with unfavorable prognosis in breast cancer. In our study, we evaluated HIF-1α and CA IX expression in patients with breast cancer. METHODS: Between June 1996 and June 2008, 111 women with breast cancer were evaluated. Estrogen receptor (ER) and progesterone receptor (PR) status and Her2/ neu expression were evaluated by immunohistochemical methods. Her-2/neu expression was also assessed by FISH method when needed. Two groups were created: ER and PR positive, Her-2/neu negative (group 1, n=56); and ER and PR negative, Her-2/neu positive (group 2, n=55). HIF-1α and CA IX expressions were investigated in both groups and results were compared. In addition, we investigated the association between HIF-1α and CA IX expressions with stage, grade, lymph node metastasis, tumor size, menopause status and survival. RESULTS: Median patient age in group 1 was 52 years (range 34-77), and in group 2 47 years (range 27-83). HIF-1α expression was detected in 26 (46.4%) of group 1 and in 46 (83.6%) of group 2 patients (p=0.0001). CA IX expression was detected in 25 (46.4%) of group 1 and in 37 (67.3%) of group 2 patients (p7equals;0.0137rpar;. In group 1, median disease free survival (DFS) was 97 months and in group 2 46 months (p=0.0308). In group 1, median overall survival (OS) was 108 months and in group 2 75 months (p=0.0339). CONCLUSION: HIF-1α and CA IX overexpressions are observed more often in ER and PR negative, Her-2/neu positive breast cancer and are associated with poor survival.

RESUMO

PURPOSE: Apart from its known effects on granulopoiesis, granulocyte-colony stimulating factor (G-CSF) is also involved in growth and progression of malignant cells. In this study we report the serum G-CSF levels and their relationship with survival in patients with glial cell tumors. METHODS: Serum G-CSF levels of 17 patients (10 male, 7 female, median age 55 years, range 19-75), with histologically proven glial cell tumors and of 17 sex- and age-matched healthy controls were assayed by enzyme-linked immunosorbent assay (ELISA). RESULTS: All patients were treated with radiotherapy and concomitant temozolomide, followed by temozolomide alone. Eight patients were treated with carboplatin plus cyclophosphamide combination as second-line chemotherapy. The median follow-up was 21 months (4-42). The median OS was 36 months (95% CI, 15.7-56.4). Serum G-CSF levels in glioma patients and healthy controls were 44.14 ± 18.89 pg/ ml and 28.84±15.65 pg/ml, respectively (p=0.027). There was no significant correlation between survival time and serum G-CSF levels (r=0.384; p=0.217). CONCLUSION: Serum G-CSF levels were high in glioma patients compared with healthy controls and they may be involved in tumor progression, but the G-CSF role in prognosis was not clarified. Further studies with larger numbers of patients must be conducted to elucidate the role of G-CSF in glial cell tumors.

RESUMO

PURPOSE: To investigate the efficacy and safety of neoadjuvant chemotherapy with docetaxel plus epirubicin with granulocyte colony-stimulating factor (G-CSF) support in locally advanced breast cancer patients. METHODS: We retrospectively evaluated the records of 39 patients with locally advanced breast cancer. All of them received neoadjuvant epirubicin 75 mg/m(2) plus docetaxel 75 mg/m(2) every 3 weeks with G-CSF support. Responding patients were subjected to breast-conserving or modified radical mastectomy. RESULTS: Four (10.3%) patients achieved clinical complete response (cCR) and 25 (64.1%) clinical partial response (cPR). Pathologic complete response (pCR) was observed in 4 patients with cCR. Ten (25.6%) patients achieved stable disease (SD), while no patient had progressive disease (PD). Grade 3 and 4 neutropenia was observed in 6 (15.3%) and 4 cases (10.3%), respectively. Febrile neutropenia was observed in 2 (5.1%) cases and anemia in 7 (17.9%) cases. Grade 1/2 mucositis was observed in 12 (30.7%) patients and grade 1/2 peripheral neuropathy in 7 (17.9%) patients. Dose reduction was necessary in 4 patients with grade 4 neutropenia. The median disease-free survival was 60 months (95% CI: 41-79 months). Median overall survival was not reached. Five-year overall survival was 64.2%. CONCLUSION: The combination of docetaxel plus epirubicin was active and tolerable in neoadjuvant treatment of locally advanced breast cancer.

RESUMO

Primary pure small cell carcinoma of the urinary bladder (SCCB) is an extremely rare tumor and accounts for less than 1% of all malignant tumors of the urinary bladder. This tumor exhibits more aggressive behavior than bladder transitional cell carcinoma. Unfortunately, optimal treatment strategy for this malignancy is still unknown. We present a patient with metastatic primary pure SCCB (stage IV) who responded to carboplatin plus etoposide combination chemotherapy and discuss the relevant current literature.

RESUMO

INTRODUCTION: Plasmacytomas are unusual causes of a sellar mass. Occasionally, they can be misdiagnosed as a nonfunctioning adenoma because of radiological and clinical similarities. LITERATURE REVIEW: We reviewed the pertinent literature and discuss here in the light of an illustrative case of our own. DISCUSSION: A 70-year-old woman presented with a recurrent hypophysial mass. Initial diagnosis of a nonfunctioning pituitary adenoma was later overruled by a repeat biopsy, which showed a plasmacytoma. The tumor stained positively for CD138 and kappa light chain. Further studies confirmed the diagnosis of multiple myeloma. The patient was successfully treated with radiotherapy followed by systemic chemotherapy. Because they have different therapeutic implications, extramedullary plasmacytomas involving pituitary gland should be considered in the differential diagnosis of a nonfunctioning pituitary mass.
