A novel modified PAIR technique using a trocar catheter for percutaneous treatment of liver hydatid cysts: a six-year experience

PURPOSE

We aimed to demonstrate the success and reliability of a novel puncture, aspiration, injection, and reaspiration (PAIR) technique in liver hydatid cysts.

METHODS

Percutaneous treatment with ultrasonographic guidance was performed in 493 hepatic hydatid cysts in 374 patients. Patients were treated with a new PAIR technique by single puncture method using a 6F trocar catheter. The results of this novel technique were evaluated with regards to efficacy and safety of the procedure and complication rates.

RESULTS

Out of 493 cysts, 317 were Gharbi type I (WHO CE 1) and 176 were Gharbi type II (WHO CE 3A). Of all cysts, 13 were referred to surgery because of cystobiliary fistulization. Recurrence was observed in 11 cysts one month later. Therefore, the success rate of the PAIR technique was 97.7% (469/480). Minor complications (fever, urticaria-like reactions, biliary fistula) were seen in 44 treated patients (12%, 44/374); the only major complication was reversible anaphylactic shock which was observed in two patients (0.5%, 2/374).

CONCLUSION

This novel modified PAIR technique may be superior to catheterization by Seldinger technique due to its efficiency, easier application, lower severe complication rate, and lower cost. Further comparative studies are required to confirm our observations.

Rapid percutaneous nephrostomy catheter placement in neonates with the trocar technique

PURPOSE

The purpose of this study was to assess the efficacy of a modified percutaneous nephrostomy procedure for grade III-IV hydronephrosis in neonates.

MATERIAL AND METHODS

Eleven neonates (five girls, six boys) with a mean age of 13.7days±9.9 (SD) (range, 4-28days) with pronounced hydronephrosis had percutaneous nephrostomy using a modified procedure. In all patients, percutaneous nephrostomy was performed with a trocar catheter under ultrasound guidance and then the catheter was placed into the collecting system without prior dilatation.

RESULTS

Technical success was achieved in all patients. There were no major procedure-related complications. There was no perirenal hematoma on control ultrasound examinations and no hematuria was observed after the procedure. The median drainage time was 75days (range: 42-120days). Two children had urinary tract infection, which was controlled by using antibiotics.

CONCLUSION

The trocar nephrostomy is a practical and feasible method, which can be used for neonates with grade III-IV hydronephrosis.

Morphometric Analysis of the Sacral Canal and Hiatus Using Multidetector Computed Tomography for Interventional Procedures

AIM

The sacral canal has been frequently used as "a passage" for minimally invasive diagnostic and therapeutic procedures for spinal diseases. The aim of the present study was to investigate morphometric analyses of the sacral canal, hiatus, and surrounding structures according to different age groups and gender by using the "multidetector computed tomography" method.

MATERIAL AND METHODS

Multiplanar-reconstructed images from 300 adult (150 females and 150 males, between 20 and 80 years old) were divided into three groups according to age and retrospectively examined. Various anatomic measurements of the sacral hiatus, surrounding structures, and sacral canal were performed. Sacral curvature angle and lumbosacral lordotic angle were noted.

RESULTS

Bony anatomic abnormalities such as absent hiatus (0.3%), complete agenesis (1%), and bony septum (2.6%) were detected in some cases. The anteroposterior (AP) diameter of the hiatus was less than 2 mm in 5% of cases. In all groups, the mean values of the hiatus AP diameter and area, and the shortest distance of the sacral canal AP diameter were shorter in the 60-80 years age group when compared with those in 20-39 years age group (p=0.01). The shortest sacral canal AP diameter was commonly located at the S2 and S3 levels in 59.2% and 33.9% of cases, respectively. The levels of maximum curvature were at S3 and S2 in 63.3% and 26.7% of cases, respectively. Median sacral curvature angles and lumbosacral lordotic angles were measured as 164° and 134°, respectively.

CONCLUSION

Sacral structures have morphometric variations. Understanding of the detailed anatomy may improve the reliability of interventional procedures.

Spontaneous retroperitoneal hemorrhage presenting as hemoperitoneum secondary to renal cyst rupture in a peritoneal dialysis patient with acquired cystic kidney disease

Spontaneous retroperitoneal hemorrhage (SRH) is a rare and potentially fatal condition. Acquired cystic kidney disease (ACKD) may cause SRH in hemodialysis patients. However, presentation of retroperitoneal hematoma as hemoperitoneum in peritoneal dialysis (PD) patients is exceedingly rare. We report a 44-year-old male PD patient who presented with hemoperitoneum secondary to retroperitoneal hematoma. The reason of SRH was rupture of the cysts of ACKD. The patient underwent unilateral nephrectomy with subsequent disappearance of hemoperitoneum. The importance of this case lies in the fact that the patients who have been receiving dialysis for a long time should be under surveillance in terms of ACKD development and potential associated complications such as cyst hemorrhage and malignancy.

Full-length silicone insoles versus ultrasound-guided corticosteroid injection in the management of plantar fasciitis: a randomized clinical trial

BACKGROUND

Plantar fasciitis often leads to disability. Optimal treatment for this clinical condition is still unknown.

OBJECTIVE

To compare the effectiveness of wearing a full-length silicone insole with ultrasound-guided corticosteroid injection in the management of plantar fasciitis.

STUDY DESIGN

Randomized clinical trial.

METHODS

Forty-two patients with chronic unilateral plantar fasciitis were allocated randomly to have an ultrasound-guided corticosteroid injection or wear a full-length silicone insole. Data were collected before the procedure and 1 month after. The primary outcome measures included first-step heel pain via Visual Analogue Scale and Heel Tenderness Index. Other outcome measures were the Foot and Ankle Outcome Score and ultrasonographic thickness of the plantar fascia.

RESULTS

After 1 month, a significant improvement was shown in Visual Analogue Scale, Heel Tenderness Index, Foot and Ankle Outcome Score, and ultrasonographic thickness of plantar fascia in both groups. Visual Analogue Scale scores, Foot and Ankle Outcome Score pain, Foot and Ankle Outcome Score for activities of daily living, Foot and Ankle Outcome Score for sport and recreation function, and plantar fascia thickness were better in injection group than in insole group (p < 0.05).

CONCLUSIONS

Although both ultrasound-guided corticosteroid injection and wearing a full-length silicone insole were effective in the conservative treatment of plantar fasciitis, we recommend the use of silicone insoles as a first line of treatment for persons with plantar fasciitis.

Soluble TWEAK independently predicts atherosclerosis in renal transplant patients

Background

Cardiovascular risk is increased in the early stages of chronic kidney disease (CKD) and also found to be ongoing in renal transplant (Rtx) patients. As a sign of atherosclerosis, increased carotid intima-media thickness (CIMT) has been widely accepted as a strong predictor of cardiovascular disease (CVD) and mortality in CKD patients. A novel markers, soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and neutrophil-to-lymphocyte ratio (NLR) were introduced as potential markers in inflammatory disorders including CKD. The role of Rtx in terms of atherogenesis is still unclear. We aimed to investigate the relationship between sTWEAK, NLR and CIMT in Rtx patients without overt CVD and to compare these results with those obtained from healthy subjects.

Methods

Cross-sectional analysis in which CIMT measurements, NLR and serum TWEAK levels were assessed in 70 Rtx patients (29 females; mean age, 40.6 ± 12.4 years) and 25 healthy subjects (13 females, mean age; 37.4±8.8 years).

Results

sTWEAK levels were significantly decreased (p=0.01) and hs-CRP, NLR and CIMT levels of Rtx patients were significantly increased compared to healthy subjects (p<0.0001, p=0.001, p<0.0001, respectively). sTWEAK was also found to be decreased when eGFR was decreased (p=0.04 between all groups). CIMT was positively correlated with sTWEAK and NLR in Rtx patients (r=0.81, p<0.0001 and r=0.33, p=0.006, respectively). sTWEAK was also positively correlated with NLR (r=0.37, p=0.002). In the multivariate analysis only sTWEAK was found to be an independent variable of increased CIMT.

Conclusion

sTWEAK might have a role in the pathogenesis of ongoing atherosclerosis in Rtx patients.

Massive haematuria successfully managed by intravesical Ankaferd in a haemodialysis patient complicated with disseminated intravascular coagulation

Massive haematuria is a life-threatening condition, demanding immediate management of bleeding. The mortality is very high in the case of delayed management of bleeding, especially in elderly patients with concomitant comorbidity. The treatment options of haematuria are wide, and depend on underlying conditions. However, therapeutic choices are limited in the presence of massive and intractable haematuria caused by disseminated intravascular coagulation (DIC). Ankaferd blood stopper (ABS) is a novel, commercially available, haemostatic agent, which has been approved by the Ministry of Health for local use in Turkey. Here, for the first time in the literature, we report a case of diffuse intravesical bleeding stopped by intravesical use of ABS in a 72-year-old man, haemodialysis patient complicated with sepsis and DIC.

Liver abscess after implantation of dental prosthesis

Pyogenic liver abscesses are rare but a life-threatening important condition. Dental procedures constitute only rare cases of pyogenic liver abscesses, with only a few cases in the literature. We report a patient with liver abscess following a dental procedure. A 74 years old diabetic male patient was admitted to our hospital with complaints of fatigue, 40 °C fever, rigors and right upper quadrant pain, 3-4 d after a dental procedure. Physical examination revealed fever and tenderness in the right upper quadrant. Laboratory examination revealed leucocytosis, elevated erythrocyte sedimentation rate and C-reactive protein and moderately elevated transaminases. An abscess was detected in radiological examination in the medial part of the left lobe of liver, neighboring the gall bladder. He was successfully treated with percutaneous abscess drainage and antibiotherapy.

Relationship between Plasma Pentraxin-3, Neutrophil-to-Lymphocyte Ratio, and Atherosclerosis in Renal Transplant Patients

BACKGROUND/AIMS: Atherosclerosis and inflammation are the most important risk factors in the pathogenesis of cardiovascular diseases (CVD) in patients with end-stage renal disease (ESRD). Pentraxin-3 (PTX-3) was shown to predict inflammation and atherosclerosis in ESRD patients. However, the role of renal transplantation (Rtx) in terms of atherogenesis is still unclear. We aimed to investigate the relationship between PTX-3, neutrophil-to-lymphocyte ratio (NLR), and carotid intima-media thickness (CIMT) in Rtx patients and healthy controls. METHODS: This was a cross-sectional study involving 29 Rtx patients (12 females, 40.1 ± 11.9 years) without overt CVD and 19 healthy subjects (9 females, 36.9 ± 8.9 years), testing the relationship between CIMT, assessed by ultrasonography, and selected biomarkers. RESULTS: CIMT, PTX-3, and high-sensitivity C-reactive protein (hs-CRP) levels of Rtx patients were found to be significantly higher compared to healthy subjects. CIMT was positively correlated with age, creatinine, uric acid, triglyceride, PTX-3, hs-CRP, and NLR, and negatively correlated with estimated glomerular filtration rate in all participants. In Rtx patients, CIMT was positively correlated with age, BMI, serum phosphorus, low-density lipoprotein, and hs-CRP. The multivariate analysis revealed that hs-CRP was found to be an independent variable of CIMT in Rtx patients. CONCLUSION: Our data showed that inflammation and atherosclerosis persist in Rtx patients. Serum hs-CRP might be a useful marker to assess these parameters in this population.

Cytomegalovirus and Aspergillus spp. coinfection in organ transplantation: a case report and review of the literature

With the advent of potent immunosuppressive options, acute rejection episodes have decreased at the expense of increased incidence of opportunistic infections in solid organ recipients. In the absence of any preventive therapy, 30–75 % of transplant recipients develop cytomegalovirus (CMV) infection. Candida spp. and Aspergillus spp. account for more than 80 % of invasive fungal infections in solid organ recipients. This co-occurrence of two commonly seen opportunistic infections may end up in fatality. Here, we present a case of concomitant Aspergillus spp. and CMV infection and discuss the relevant literature. A 54-year-old male patient presented with fever, shortness of breath, and chest pain on the 9th posttransplant week after renal transplantation. CMV-DNA by polymerase chain reaction (PCR) was 1,680,000 copies/ml, thus, valganciclovir dose was increased. There were inspiratory crackles at both lung bases, and chest computed tomography (CT) revealed multiple fungal balls throughout the right lung. Galactomannan antigen was positive, and voriconazole and other antimicrobials were subsequently added to the treatment. At the end of the therapy, on control CT, pneumonic consolidation had disappeared, sputum cultures didn’t show Aspergillus spp., and CMV-DNA reduced to 700 copies/ml. The patient showed a favorable clinical response to combined treatment; fever, dyspnea, and pleuritic chest pain disappeared. Both CMV disease and aspergillosis may present as pulmonary disease; thus, the characterization of one may not preclude the search for the other and the timely initiation of treatment is of paramount importance for good outcomes.

The relationship between oxidative stress, inflammation, and atherosclerosis in renal transplant and end-stage renal disease patients

OBJECTIVES

Cardiovascular risk is increased in the early stages of chronic kidney disease (CKD) and is also found to be ongoing in renal transplant (Rtx) patients. As a sign of atherosclerosis, increased carotid intima-media thickness (CIMT) has been widely accepted as a strong predictor of cardiovascular disease (CVD) and mortality in the end-stage renal disease (ESRD) patients. Ischemia-modified albumin (IMA), pentraxin-3 (PTX-3), and neutrophil-to-lymphocyte ratio (NLR) were introduced as oxidative stress and inflammatory biomarkers in ESRD. The role of Rtx in terms of atherogenesis, oxidative stress, and inflammation is still unclear. We aimed to investigate the relationship between IMA, PTX-3, NLR, and CIMT in Rtx patients without overt CVD and to compare these results with those obtained from healthy subjects and ESRD patients receiving hemodialysis (HD) and peritoneal dialysis (PD).

DESIGN AND METHODS

Cross-sectional analysis in which CIMT measurements, NLR, and serum PTX-3 and IMA levels were assessed in 18 Rtx patients (10 females; mean age: 40.0 ± 13.3 years), 16 PD patients (7 females; 40.2 ± 12.9 years), 14 HD patients (8 females; 46.6 ± 10.7 years), and 19 healthy subjects (9 females; 36.9 ± 8.9 years).

RESULTS

IMA, PTX-3, and high-sensitive C-reactive protein (hs-CRP) levels, NLR, and CIMT of Rtx patients were found to be significantly higher compared with healthy subjects ( p = 0.04, p < 0.0001, p < 0.005, p = 0.005, and p = 0.005, respectively). IMA level was positively correlated with hs-CRP and PTX-3 levels, NLR, and CIMT when all participants were included (r = 0.338, p = 0.005; r = 0.485, p < 0.0001; r = 0.304, p = 0.013; and r = 0.499, p < 0.0001, respectively).

CONCLUSION

There has been ongoing inflammation, oxidative stress, and atherosclerosis in Rtx patients.

Peri-aortic fat tissue thickness in peritoneal dialysis patients

BACKGROUND

Thoracic peri-aortic fat tissue (PFT) and epicardial adipose tissue (EAT) are metabolically active visceral fat deposits surrounding the thoracic aorta and the heart, respectively. Various studies have demonstrated a positive predictive value of both PFT and EAT for coronary artery disease in the general population. In the present study, we aimed to investigate PFT thickness and the independent predictors of PFT in peritoneal dialysis (PD) patients. ♢

METHODS

Our cross-sectional study enrolled 35 PD patients (10 women, 25 men) and 30 age-and-sex-matched healthy subjects (15 women, 15 men). We measured PFT, thoracic artery calcification (TAC), EAT, and coronary artery calcification (CAC) by electrocardiogram-gated 64-multi-detector computed tomography. ♢

RESULTS

The measured PFT, EAT, CAC, and TAC were significantly higher in the PD group than in the healthy subjects (p < 0.05 each). In the PD group, PFT and TAC were significantly correlated (r = 0.33, p = 0.007). Also, PFT measurements were positively correlated with EAT and total CAC in the PD and the control group alike (r = 0.58, p = 0.001 and r = 0.54, p = 0.01 respectively). A stepwise linear regression analysis revealed that age, duration of hypertension, and being a PD patient were independent predictors of PFT. ♢

CONCLUSIONS

Measured PFT was higher in PD patients than in healthy subjects and, in the PD population, was also shown to be related to calcification scores and EAT.

Blue rubber bleb nevus syndrome: successful treatment with sirolimus

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder with characteristic vascular malformations of the skin, gastrointestinal system, and, less often, other organ systems. The characteristic cutaneous lesions consist of deep-blue, soft, rubbery blebs, which are easily compressible. The most serious complication is abundant gastrointestinal bleeding. We describe the case of an 8-year-old girl with diagnosed BRBNS who had multiple venous malformations all over her body, importantly, throughout the gastrointestinal tract, mouth, esophagus, stomach, small bowel, and colon. She presented with recurrent massive gastrointestinal bleeding and soft tissue hematoma despite prednisolone and α-interferon therapy. We started low-dose sirolimus as an antiangiogenic agent. The vascular masses were reduced rapidly and there was no gastrointestinal bleeding and muscular hematoma after sirolimus therapy. There was no drug adverse reaction at 20-month follow-up. To the best of our knowledge, this is the first report related to the use of sirolimus in a patient with BRBNS.

Effects of secondary amyloidosis on arteriovenous hemodialysis fistula outcomes and intradialytic hypotension: a case-control study

Amyloid fibrils can affect vascular structure through deposition and by causing nitric oxide depletion and increase of asymmetric dimethyl arginine. Patients with amyloidosis are prone to development of hypotension. Hypotension may also affect the maturation of arteriovenous fistula (AVF) and may set the stage for formation of thrombosis and fistula failure. Thus, we aimed to evaluate effects of secondary amyloidosis on AVF outcomes and intradialytic hypotension. This is a case-control study which included 20 hemodialysis patients with amyloidosis and 20 hemodialysis patients without amyloidosis as control group. All patients underwent Doppler ultrasound of AVF. A thorough fistula history and baseline laboratory values along with episodes of intradialytic hypotension and blood pressure measurements were recorded. There was no difference between the groups regarding age, gender, body mass index, presence of comorbidities, hypertension, and drug use. Systolic and diastolic blood pressures were similar (119 ± 28/75 ± 17 and 120 ± 14/75 ± 10 mmHg for patients with and without amyloidosis, respectively). Intradialytic hypotension episodes were also similar. Patients with amyloidosis had significantly lower serum albumin and higher C-reactive protein values compared to control hemodialysis patients. AVF sites and total number of created fistulas were similar in both groups. Flow rates of current functional AVFs were not different between the groups (1084 ± 875 and 845 ± 466 mL/minute for patients with and without amyloidosis, respectively, p:0.67). Patency duration of first AVF was not different between the groups. Clinical fistula outcomes and rate of intradialytic hypotension episodes were not significantly different between patients with and without secondary systemic amyloidosis.

The Relationship between Epicardial Adipose Tissue and Coronary Artery Calcification in Peritoneal Dialysis Patients

BACKGROUND: Atherosclerosis, endothelial dysfunction, coronary artery calcification (CAC), and left ventricular hypertrophy are the most commonly encountered risk factors in the pathogenesis of cardiovascular disease in end-stage renal disease patients. Epicardial adipose tissue (EAT) is the true visceral fat depot of the heart. The relationship between coronary artery disease and EAT has been shown in healthy subjects and patients with a high risk of coronary artery disease. In the present study, we aimed to investigate the relationship between EAT and CAC in peritoneal dialysis (PD) patients. Patients and Methods: Forty-five PD patients (18 females, 27 males, with a mean age of 50.6 ± 15 years) and 25 healthy subjects (12 females, 13 males, with a mean age of 52.4 ± 10.7 years) were enrolled in the study. EAT and CAC score (CACS) measurements were performed by a multidetector computed tomography scanner. RESULTS: EAT of the PD patients was significantly higher than that of the healthy subjects (p = 0.02). When patients were divided into two subgroups (group 1: CACS ≤10, n = 20; group 2: CACS >10, n = 25), EAT was also significantly higher in group 2 patients than in group 1 patients and healthy subjects. Age and EAT were also found to be correlated with CACS ≥10. CONCLUSION: There is a relationship between the anatomic assessment of coronary artery lesions by multidetector computed tomography and EAT in PD patients. This relationship might be attributed to increased inflammation and proinflammatory cytokines in uremic patients.

Predictors of kidney dimensions measured by multi-detector computed tomography (MDCT) in 930 middle-aged and elderly patients

PURPOSE

A few studies investigated renal size using computed tomography (CT) in middle-aged and elderly patients while taking renal function into account. Thus, we aimed to assess kidney dimensions and their predictors in patients without known renal disease by multi-detector computed tomography (MDCT).

METHODS

This is a 6-month-long prospective observational study. Estimated glomerular filtration rate (eGFR) was calculated with Cockcroft-Gault (CG) and modification of diet in renal disease (MDRD) formulas. Pole-to-pole kidney length (R1) was determined from coronal and sagittal oblique images. Kidney length (R2), width (R3), and parenchymal thickness were measured in axial slices.

RESULTS

The data of the 930 patients were included in this study. CG-eGFR was more closely correlated with R1, R2, and R3 than MDRD-eGFR. CG-eGFR, female gender, and presence of diabetes mellitus were independent predictors of R1 size in logistic regression analyses.

CONCLUSION

Kidney sizes diminish with advancing age. CG-eGFR shows a better correlation with kidney dimensions compared with MDRD. Overall, age was a stronger determinant of eGFR than renal dimensions.

Epstein-Barr virus encephalitis: findings of MRI, MRS, diffusion and perfusion

Epstein-Barr virus is an infection that is known as infectious mononucleosis. Even though the central nervous system is not a primary region of involvement of this disease, neurological complications are reported rarely. In this case report, we evaluated a 15-month-old male who presented to the pediatric neurology clinic due to high fever and a neurologic attack. His serological tests and radiological examinations (magnetic resonance imaging (MRI), MR spectroscopy (MRS), diffusion-weighted imaging (DWI) and MR perfusion) were consistent with Epstein-Barr virus encephalitis, which is a very rare complication of infectious mononucleosis. Additionally, we discuss the MRI, MRS, DWI and MR perfusion findings of our case, which were different from other cases reported in the literature.

Relationship between color M-mode echocardiography flow propagation and cardiac iron load on MRI in patients with thalassemia major

PURPOSE

Myocardial iron overload remains an important problem and results in cardiac dysfunction in patients with thalassemia major (TM). The ratio of color M-mode flow propagation velocity to early diastolic transmitral flow velocity (E/Vp) in echocardiography is a marker of increased left ventricular filling pressure, which is independent of preload, afterload, and heart rate. We examined the relationship between E/Vp and iron loading in patients with TM using cardiac magnetic resonance imaging (MRI).

MATERIALS AND METHODS

Twenty-one TM patients and 21 age-matched healthy controls were enrolled in the study. Transmitral flow, pulmonary vein velocities, and Vp were obtained by two blinded echocardiographers. Left ventricular isovolumetric relaxation time (IVRT) was measured in the apical long axis by echocardiography. All patients also underwent MRI for cardiac T2* evaluation of iron overload. An increased E/Vp was defined as > 1.5.

RESULTS

The E/Vp ratio was increased in TM patients compared with control subjects (1.7±0.4 and 1.2±0.2, P < 0.01, respectively). There was no correlation between E/Vp and cardiac T2* value. E/Vp was significantly correlated with IVRT (r=0.51, P = 0.02). In addition, the cardiac T2* value was comparable in patients with an E/Vp > 1.5 and E/Vp ≤1.5 (21.1±9.8 ms vs. 22.3±8.0 ms, P = 0.80, respectively).

CONCLUSION

E/Vp may be a marker of diastolic abnormality that is independent from myocardial iron load in TM patients with preserved left ventricular function.

Radiofrequency ablation of phalangeal osteoid osteoma: technical challenges encountered in small bones

Osteoid osteoma, a benign bone tumor, is characterized by a generally less than 1 cm nidus surrounded by a zone of reactive sclerosis. It is frequently located in the femur and tibia; on the other hand in up to 5% of cases it may be presented in upper extremities. In previous years, its treatment was usually open surgery with en-bloc resection or curettage of the tumor. Various minimal invasive percutaneous treatments including radiofrequency ablation became popular in last years. In this report, the difficulties encountered during radiofrequency ablation treatment in small bones is described in a 19-year-old female case of osteoid osteoma.

Rare Thyroid Cartilage and Diaphragm Metastases from Lung Cancer Visualized on F-18 FDG-PET/CT Imaging

Positron emission tomography (PET) with F-18 fluorodeoxyglucose (FDG) has evolved as a useful imaging modality in the assessment of a variety of cancers, especially for tumor staging and post treatment monitoring. It provides metabolic information. Although, when used alone, relative lack of anatomic landmarks, is a major limitation of PET imaging, this limitation of PET imaging is overcome by the availability of integrated PET/CT imaging. PET and CT images are acquired in one procedure, yielding fused anatomical and functional data sets. Studies with integrated PET/CT imaging have shown promising results. In this case, we present an interesting integrated PET/CT imaging in a lung cancer patient with rare, diaphragm and thyroid cartilage metastases.

The relationship between epicardial adipose tissue and malnutrition, inflammation, atherosclerosis/calcification syndrome in ESRD patients

BACKGROUND AND OBJECTIVES

Malnutrition, inflammation, atherosclerosis/calcification (MIAC) and endothelial dysfunction are the most commonly encountered risk factors in the pathogenesis of cardiovascular disease in ESRD patients. Epicardial adipose tissue (EAT) is the true visceral fat depot of the heart. The relationship between CAD and EAT was shown in patients with high risk of coronary artery disease. In this study, we aimed to investigate the relationship between EAT and MIAC syndrome in ESRD patients.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Eighty ESRD patients and 27 healthy subjects enrolled in this cross-sectional study. EAT and coronary artery calcification score were measured by a multidetector computed tomography (MDCT) scanner. Patients with serum albumin <3.5 mg/dl were defined as patients with malnutrition; those with serum C-reactive protein level >10 ng/dl (normal range, 0-5 ng/dl) had inflammation; and those with CACS >10 had atheroscleosis/calcification.

RESULTS

Total CACS and EAT measurements were significantly higher in ESRD patients when compared with healthy subjects. There was a statistically significant relationship between EAT and CACS in ESRD patients (r = 0.48). EAT measurements were higher in PD patients than HD patients. Twenty-four of the patients had no component, 31 had one component, 17 had two components, and nine had all of the MIAC components. EAT was found to be significantly increased when the presence of MIAC components increased. EAT was positively correlated with age, body mass index, and presence of MIAC. These parameters were also found as independent predictors of increased EAT.

CONCLUSIONS

We found a relationship between EAT and components of MIAC syndrome in ESRD patients.

Adrenal insufficiency is rarely associated with adrenal haemorrhage. In this report, a case of polycythaemia vera with adrenal haemorrhage and insufficiency has been presented.

The role of FDG-PET/CT in ovarian cancer patients with high tumor markers or suspicious lesion on contrast-enhanced CT in evaluation of recurrence and/or in determination of intraabdominal metastases

OBJECTIVES

This retrospective study was designed to investigate the role of fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in determination of recurrence and/or intraabdominal metastasis in patients with ovarian cancer having increased tumor markers or suspicious lesion detected by a contrast-enhanced abdominal CT (ceCT).

MATERIALS AND METHODS

A total of 34 female patients who were treated for histopathologically proven ovarian cancer, underwent PET/CT examination for restaging and suspected recurrence. Patients with pathology report, tumor marker levels, ceCT and PET/CT performed within one month were included in the study.

RESULTS

A total of 34 patients were included in the study. 25 of 34 patients had high tumor marker (CA 125) level. The remaining 9 patients had suspected recurrence on ceCT imaging with normal tumor marker levels. Recurrence was confirmed by re-operation and biopsy (n=4), clinical and imaging follow-up (n=21) in 25 patients with elevated tumor markers. Recurrent disease was not shown in 5 of 25 patients on ceCT imaging and 1 of 25 patients on PET/CT imaging with high CA125 values. Both ceCT and PET/CT revealed recurrent disease in 19 of 25 patients. PET/CT showed more lesions in 11 of 19 patients. Sensitivity, specificity and accuracy of the PET/CT were 96.1%, 100% and 97%, respectively.

CONCLUSION

PET/CT is found as a beneficial method for detection of the recurrence, in patients with increased serum CA 125 level and negative CT findings or with normal CA 125 level and recurrence detected by CT which was performed due to clinical symptoms.

Aspergillus thyroiditis in a renal transplant recipient mimicking subacute thyroiditis

Fungal pathogens are increasingly encountered after renal transplantation. Aspergillus causes significant morbidity and mortality in transplant patients. Fungal thyroiditis is a rare occurrence owing to unique features of the thyroid gland. Most cases are caused by Aspergillus species and have been described in immunocompromised patients. Presentation may be identical with that of subacute thyroiditis, in which hyperthyroidism features and painful thyroid are the prominent findings. Diagnosis can be ascertained by fine-needle aspiration of thyroid showing branching hyphae of Aspergillus. We describe a renal transplant patient who developed Aspergillus thyroiditis as part of a disseminated infection successfully treated with voriconazole.

Presentation of two cases with hypermobility syndrome and review of the related literature

The aim of this study was to show that simple criteria like Beighton and Brighton criteria are sufficient to determine a diagnosis of hypermobility and may be useful prior to performing excessive diagnostic studies on children with variable joint pain and limited range of motion. Additionally, this study underlines how limitations of deformed joints can be restored with physiotherapy, which can also help preventing further complications of hypermobility. This study reports the case of a five-year-old girl and her 10-year-old brother, who both were suffering from difficulty in holding a spoon. Our diagnosis was hypermobility syndrome. The patients showed significant improvement with physiotherapy of the elbows. Evaluating patients for hypermobility in routine rheumatologic examination will prevent unnecessary diagnostic studies and treatments. Moreover, although the most common initial symptom of hypermobility is pain (usually in the knees), a limited range of motion due to subluxations in any other joints, like the elbows, may be the first symptom.
