Prostate-specific membrane antigen (PSMA) is a membrane glycoprotein that is overexpressed in prostate cancer cells. It is also expressed in other normal tissues and several other malignant and benign diseases. We present a case of a 69-year-old man with history of prostate adenocarcinoma who underwent 18F-PSMA-1007 PET/CT due to suspected biochemical recurrence. PET/CT showed 18F-PSMA-1007 uptake in healing rib fractures with no other pathologic findings. Clinicians reporting 18F-PSMA-1007 PET/CT should be aware of this potential pitfall, especially in nontypical trauma pattern (eg, solitary osseous lesion) mimicking bone metastases.

Background Thyroid cancer (TC) is one of the fastest growing cancers all over the world. Differentiated thyroid cancer (DTC) is the most frequent subtype of TC. When appropriate treatment is given, the prognosis for the patient is generally excellent. Despite the generally good prognosis of thyroid carcinomas, the symptoms may range from emotional to physical discomfort, depending on the thyroid hormone status, which can severely affect the patient. Moreover, the diagnostic and therapeutic procedures that DTC patients have to undergo, such as thyroidectomy and radioiodine therapy, significantly affect their mental and physical well-being. Often, the physician only addresses the favorable prognosis of DTC compared with other cancer types and neglects to assess issues related to the quality of life (QoL) of the patient; this was the reason we decided to design a mobile app for DTC patients and their caregivers. Objective The aim of this study is to research the feasibility and applicability of an mHealth app tailored to DTC patients, as reflected in their QoL. The main features of the developed app offer access to useful information about thyroid cancer, diagnostic tests, and the appropriate therapy administered to DTC patients. Methods Based on the existing literature, we created an up-to-date information platform regarding TC and especially DTC. In order to develop an effective app that can be implemented in current health care, we designed a section where the patient and physician can keep a medical record in an effort to enable access to such information at any time. Finally, we designed a user-friendly notification program, including pill prescription, follow-up tests, and doctor visit reminders in order to equally facilitate the lives of the patient and physician. Results Having developed this mobile app, we aim to conduct a pilot quasiexperimental interventional trial. Our intention is to enroll at least 30 TC patients and assign them to intervention or control groups. Both groups will receive standard care for treating and monitoring TC, and the intervention group will also receive and use the DTC app. TC patients’ QoL will be assessed for both control and intervention groups in order to examine the effectiveness of the DTC app. QoL will be assessed through the QoL core questionnaire European Organisation for Research and Treatment of Cancer (EORTC) QLQ-THY34 in combination with the EORTC QLQ-C30 questionnaire through quantitative statistical analysis. Conclusions The use of mHealth apps can play a significant role in patient education, disease self-management, remote monitoring of patients, and QoL improvement. However, the main limitation of the majority of existing studies has been the lack of assessing their usefulness as well as the absence of specific instruments to carry out this assessment. In light of those considerations, we developed a mobile app tailored to the needs of DTC patients. Furthermore, we evaluated its contribution to the QoL of the patients by using the EORTC QLQ-THY34 questionnaire, an accurate and safe instrument for the evaluation of the QoL in TC patients, while supporting future planned endeavors in the field.

A 16-year-old male patient was admitted to hospital because of a fainting episode which was accompanied by diarrhoea that was dark red. All investigations were normal except a low haematocrit, a technetium-99m pertechnetate abdominal scan, which showed a large area of moderate activity in the upper left abdomen, and digital subtraction angiography, which showed bleeding in the same area where the abnormal finding on the pertechnetate scan was found. Ectopic gastric mucosa and a deep ulcer in an otherwise normal jejunum were found during the urgent exploratory laparotomy.

Background: Νeuroendocrine tumors of the lungs are rare arising in the thymus and gastro-entero-pancreatic tract and belonging to foregut of neuroendocrine tumors. The aim of the present prospective study was to estimate the potential impact of single-photon emission computed tomography somatostatin receptor scintigraphy using 99mTc-Tektrotyd on diagnosis, treatment response, and prognosis in patients with neuroendocrine tumors of the lungs. Methods: Thirty-six patients with neuroendocrine tumors of the lungs were evaluated by using 99mTc-HYNIC-TOC scintigraphy. The scintigraphic results were compared to liver tissue uptake (Krenning score). Likewise, the functional imaging results were compared with biochemical indices including chromogranin A, neuroendocrine-specific enolase, and insulin-like growth factor 1 at the time of diagnosis (baseline) and disease progression. Results: The number of somatostatin receptors, expressed with Krenning score, did not show any correlation with the survival of patients both at baseline ( P = .08) and at disease progression ( P = .24), and scintigraphy results did not relate significantly to progression-free survival. Comparing the results of 99mTc-HYNIC-TOC scintigraphy according to the response of patients in the initial treatment, a statistically significant negative correlation was observed both in the first and in the second scintigraphy with patients’ response ( P = .001 and P < .001, respectively). The concentrations of biochemical markers were in accordance with scintigraphy results in the diagnosis. Conclusion: This study indicates that 99mTc-HYNIC-TOC scintigraphy appears to be a reliable, noninvasive technique for detection of primary neuroendocrine tumors and their locoregional or distant metastases, although it cannot be used as a neuroendocrine tumors of the lungs predictive technique.

Background: Thyroid cancer is the most common malignant disease of the endocrine system and radioiodine therapy (RAIT) is still very often used, resulting in patients staying hospitalized for a few days alone and without visitors, augmenting their stress and discomfort. Our objective was to find simple ways of improving RAIT patients' feelings and perceived quality of the nuclear medicine (NM) department services. Material and methods:We designed a two-year study in order to enhance RAIT patients' perceived quality of the nuclear medicine (NM) department services and expectations' fulfillment. A questionnaire was used in order to capture patients' perceived quality and expectations from their RAIT.Results: 549 replies were collected. Many intrinsic and extrinsic determinants were found to be positively or negatively related to the perceived quality and fulfillment of patients' expectations of receiving RAIT. A 1% increase could be achieved by spending 110 € per RAIT room. Conclusions:In this article, we present some easily implemented changes in both personnel behavior and room amenities that could, at least in theory and based on our results, offer a 37.9% improvement in RAIT patients' perceived quality and expectations' fulfillment at a cost of 4169 €.
