Abstract Introduction Magseed is a novel localization technology in which a tiny seed is inserted to accurately mark the site of breast tumour. These can be detected intra-operatively by sentimag localization system. It aids localization of impalpable breast lesions improving margin clearance rates. Method A prospective study of first fifty Magseed localised breast tumour and axillary node excisions in Clatterbridge General Hospital. Results A total of 50 patients had 52 Magseed inserted. n = 14 was symptomatic, n = 35 was screen detected and n = 1 was an incidental finding on surveillance mammogram for a B3 lesion. 30 seeds were inserted on the right and 22 were inserted on the left (two were bilateral). 44 seeds were inserted under ultrasound guidance and the rest were targeted under stereo guidance (n = 8). Deployment of two resulted in malposition requiring wire localization. Mean age of subjects was 59.76 (range 31-81) years. Mean time to surgery after magseed insertion was 8.04 (range 1-27) days. Mean weight of the specimen was 48.57(range 10-264) gm. Mean size of the lesions was 20.32 (range 8-65) mm. Redo surgery for margin clearance was performed bringing the re-excision rate to 15.38% (n = 8). Conclusions We conclude that Magseed localization of breast tumours is a safe and reliable technique

<b><i>Background and Objective:</i></b> Placing an endotracheal tube (ETT) in neonates is challenging and currently requires timely radiographic confirmation of correct tip placement. The objective was to establish the reliability of ultrasound (US) for assessing ETT position in the neonatal intensive care unit (NICU), time needed to do so, and patients’ tolerance. <b><i>Methods:</i></b> A prospective study on 71 newborns admitted to our NICU whose ETT placement was evaluated with US (ETT-echo) and confirmed on chest X-rays (CXR). Data were collected by 3 operators (2 neonatologists and a resident in pediatrics). The right pulmonary artery (RPA) was used as a landmark for US. The distance between the tip of the ETT and the upper margin of the RPA was measured using US and compared with the distance between the tube’s tip and the carina on the CXR. <b><i>Results:</i></b> Seventy-one intubated newborns were included in the study (<i>n</i> = 34 &#x3c; 1,000 g, <i>n</i> = 18 1,000–2,000 g, <i>n</i> = 19 &#x3e; 2,000 g). Statistical analysis (Bland-Altman plot and Lin’s concordance correlation coefficient) showed an excellent consistency between ETT positions identified on US and chest X-ray. The 2 measures (ETT-echo and CXR) were extremely concordant both in the whole sample and in the subgroups. Minimal changes in patients’ vital signs were infrequently observed during US, confirming the tolerability of ETT-echo. The mean time to perform US was 3.2 min (range 1–13). <b><i>Conclusions:</i></b> ETT-echo seems to be a rapid, tolerable, and highly reliable method worth further investigating for future routine use in neonatology with a view to reducing radiation exposure.

Bone morphogenetic proteins (BMPs) belong to the TGF-β super family, and are essential for the regulation of foetal development, tissue differentiation and homeostasis and a multitude of cellular functions. Naturally, this has led to the exploration of aberrance in this highly regulated system as a key factor in tumourigenesis. Originally identified for their role in osteogenesis and bone turnover, attention has been turned to the potential role of BMPs in tumour metastases to, and progression within, the bone niche. This is particularly pertinent to breast cancer, which commonly metastasises to bone, and in which studies have revealed aberrations of both BMP expression and signalling, which correlate clinically with breast cancer progression. Ultimately a BMP profile could provide new prognostic disease markers. As the evidence suggests a role for BMPs in regulating breast tumour cellular function, in particular interactions with tumour stroma and the bone metastatic microenvironment, there may be novel therapeutic potential in targeting BMP signalling in breast cancer. This review provides an update on the current knowledge of BMP abnormalities and their implication in the development and progression of breast cancer, particularly in the disease-specific bone metastasis.

Abstract Background Clinical guidelines do not recommend further investigation for occult malignancy in the scenario of unprovoked venous thromboembolism in the absence of additional clinical features suggestive of malignancy. We present the case of a young gentleman with pulmonary embolism who was diagnosed with testicular seminoma despite lack of symptoms or signs suggestive of malignancy. This is a unique case describing a scenario not well documented in existing literature where contravention of clinical guidelines had a potentially advantageous outcome for the patient. Case presentation A 37-year-old white male presented with seemingly unprovoked acute pulmonary embolism with right heart strain. He did not have any predisposing factors for venous thromboembolism and did not have any symptoms or signs suggestive of malignancy. Clinical guidelines do not recommend further investigation to screen for malignancy in this scenario. Despite this, our young, otherwise healthy patient proceeded to computed tomography scanning, resulting in the diagnosis of localized testicular seminoma. Testicular ultrasound described normal-sized testes (despite a discrete lesion in the right testis), suggesting this was not detectable by the patient or clinician on routine examination. The patient was anticoagulated and had an inferior vena cava filter inserted to facilitate orchidectomy followed by adjuvant radiotherapy. Conclusions This case highlights the importance of considering malignancy in seemingly unprovoked venous thromboembolism and the availability of guidelines to direct further investigation. Our patient’s treatment was not in line with clinical guidelines and was considered a “lucky find.”

Stage Renal Disease

The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal. We decided to utilize the left kidney for a 25-year-old male patient with end-stage renal disease, and following the ex vivo repair using the recipient epigastric vessels and saphenous veins, we completed the transplantation in the right pelvic fossa. The postoperative period was uneventful, and at 8 months from the surgery, the graft remains functional. The surgical repair of renal artery aneurysms followed by immediate kidney transplantation is a safe technique and an effective replacement therapy for recipients. The incidental finding of isolated aneurysmal disease in renal arteries should not exclude graft potential availability for transplantation following repair.

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a sexual developmental disorder. In this disorder, there is a congenital absence of the uterus and vagina with normal external genitalia. The etiology is not well understood. Variations of this condition exist that may include congenital abnormalities and psychological problems. In this article, we discuss the case of a 47-year-old African American female who presented with acute renal failure, solitary right kidney, and a pelvic mass extending from the pelvis to the right hypochondrium determined to be a fibroid. The patient was managed by a multidisciplinary team, dialyzed, and planned for removal of the mass. While understanding the low probability of having fibroids without a uterus, fibroids should not be excluded from such patients. It is also important to consider the emotional and psychological well-being of such patients.

AbstractIntroduction: We describe a technique we call “Meso-transjugular intrahepatic portosystemic shunt (MTIPS)” for relief of portal hypertension secondary to portal vein thrombosis (PVT) using combined surgical and endovascular technique. Materials and Methods: Nine adult patients with PVT underwent transjugular intrahepatic portosystemic shunt through a combined transjugular and mesenteric approach (MTIPS), in which a peripheral mesenteric vein was exposed through a minilaparotomy approach. The right hepatic vein was accessed through a transjugular approach. Mechanical thrombectomy, thrombolysis, and angioplasty were performed when feasible to clear PVT. Results: All patients had technically successful procedures. Patients were followed up for a mean time of 13.3 months (range: 8 days to 3 years). All patients are still alive and asymptomatic. Conclusion: We conclude that MTIPS is effective for the relief of portal hypertension secondary to PVT.

Abstract Objective To assess fetal hemodynamic changes in response to anemia in early gestation, using fetal Hb Bart’s disease as a study model. Methods A prospective study was conducted on pregnancies at risk for fetal Hb Bart’s disease at 12–14 weeks of gestation. Fetal hemodynamics were comprehensively assessed by 2D ultrasound, Doppler velocity, and cardio-STIC just prior to the invasive procedure for diagnosis. The various hemodynamic parameters of the affected and unaffected fetuses were compared. Results Of 56 fetuses at risk, 17 had Hb Bart’s disease and 39 were unaffected. The right and combined ventricular cardiac outputs (CO) were significantly higher in the affected fetuses (0.993 vs. 1.358; p < 0.001 and 1.010 vs. 1.236; p < 0.001, respectively), whereas the left CO tended to be higher but not significantly (1.027 vs. 1.113; p = 0.058). Cardiac dimensions, middle-cerebral artery peak systolic velocity, Tei index, and isovolemic contraction time were significantly increased, while the global sphericity index was significantly decreased. Interestingly, cardiac preload, ventricular wall thickness, shortening fraction, isovolemic relaxation time, and fetal heart rate were unchanged. Four fetuses had hydropic changes, but all cardiac functions were normal. Conclusion Fetal anemia induces hypervolemia and increases cardiac output to meet the tissue oxygen requirement, resulting in an increase in size without hypertrophy, volume load without pressure load, and a decrease in the globular sphericity index. The heart works very well but works harder, especially systolic ventricular load. Hydrops fetalis due to anemia appears not to be caused by heart failure as previously believed but rather by volume load with high vascular permeability at least in early pregnancy.

Abnormal communications between the systemic and pulmonary venous systems are rare but can present as a opacity on chest radiograph. A solitary vessel communicating as a fistula directly between the systemic arterial circulation and the pulmonary venous system is not widely described. These may have significant implications in the long-term cardiovascular health of an individual acting as a left to right shunt. There is no clear consensus as to the management, but surgical management and endovascular embolisation have been successfully used. We present a case where a systemic arteriaopulmonary fistula originating from the abdominal aorta and connecting to the right inferior pulmonary vein manifested as an incidental finding on a chest radiograph and was further evaluated on cross-sectional imaging in a young patient. Chest radiographs are non-specific and it is important to be aware of the less frequent but important pathologies that can be picked up on plain chest radiographs, which inturn should warrant further investigation. This is presented in conjunction with a review of the available literature along with a discussion regarding the differential diagnosis and management applicable to the general clinician.

Fishing resources are important generators of income and food for the rural and urban people in the Amazon. The present paper investigates fishing and environmental variables determining fishing production landed in Manaus and evaluates the relative abundance of commercial fishes in the different sub-systems of the Central Amazon basin. Information collected was used to test the new catch index derived from multiple regressions with the following significant variables: number of fisherman days fishing; distance of the fishing ground from Manaus; amount of ice carried during the trip; and river level. There were no significant differences between mean catch values of the Purus, Madeira and Juruá sub-systems. These results suggest that the tributaries of the right margin were very similar and were the most productive in commercial terms. The actual production varies according to the recent magnitude of fishing effort, environmental variations and operational aspects of fishing, particularly ice consumption.

OBJECTIVE: Trigeminal neuralgia is the most common facial pain. It may be treated with percutaneous balloon compression (PBC), which is considered to be a safe and efficient procedure. The purpose of this study was to review our results with PBC and to assess the factors influencing the outcome. METHOD: A multivariate analysis was used to study 39 patients during a 50-month postoperative period. RESULTS: There was predominance of the female gender (54%), the right side of the face (84%) and V2V3 roots of trigeminal nerve (33%). The mean age was 62.3 years. No major complications or deaths occurred. Among all variables, postoperative hypoesthesia was the single prognostic factor capable of positively influencing the results (p=0.02). Most patients (80%) were pain-free after 50 months with a 90% satisfaction rate. CONCLUSION: PBC was a safe procedure with low morbidity, no mortality, high approval ratings, and was an important improving on patients' quality of life.
