[Hemolysis and metastatic cancer in an elderly man]. / Iäkkään miehen hemolyysi ja levinnyt syöpä.

Sometimes correct diagnoses is reached after many years and even after decades. Our patient had for decades suffered from a hemolytic disease, life-threatening, metastatic cancer at the age of almost 90 years was also suspected. The patient was finally diagnosed as having mild hereditary spherocytosis and the associated paraspinal extramedullar hematopoiesis as well as an osteoporotic vertebral fracture caused by osteoporosis.

[68Ga-DOTA-PET for neuroendocrine tumours]. / Somatostatiinireseptoreiden PET-TT-kuvaus 68Ga-DOTA-peptideillä parantaa neuroendokriinisten kasvainten diagnostiikkaa.

Neuroendocrine tumors (NET) are found in several organs and called NET tumors. They are relatively rare, most of them giving no symptoms and remaining undetected. Most NETs arise from the gut, stomach and bronchus. These tumors are diagnosed either by histology or by imaging. A typical feature of NETs is abundance of somatostatin receptors on the cell surface, which makes it possible to image the tumor by nuclear methods as well as estimate the response to treatment by somatostatin analogues ("theranostics"). In order to improve the diagnosis of NETs we started to produce 68Ga-DOTA peptides for PET.

[Arranging first aid as voluntary work in Jukola-relay]. / Jukolan viestin 2012 ensiavun järjestäminen talkootyönä.

Various aspects must be anticipated in the planning of first aid in the massive orienteering contest Jukola-relay. Spreading of the event to a wide forest terrain area, beyond the reach of roads, poses a challenge for the evacuation of injured persons. The communication chains must be secured. In addition to the competition center, first aid points must be devised at various off-road points. Capable volunteers must be recruited in sufficient numbers. Establishing a temporary, health center standard emergency preparedness for approximately 50 000 people necessitates the acquisition of equipment and medicines for emergency care. Preparations must be made for the treatment of injuries and attacks of illness among the competitors, the audience and the volunteers.

Locally advanced esophageal adenocarcinoma: response to neoadjuvant chemotherapy and survival predicted by ([18F])FDG-PET/CT.

BACKGROUND: ([18F])fluorodeoxyglycose-Positron Emission Tomography/Computer Tomography (([18F])FDG-PET/CT) is commonly used in staging of locally advanced esophageal cancer. Its predictive value for response to neoadjuvant therapy and survival after multimodality therapy is controversial. METHODS: Sixty-six consecutive patients with locally advanced adenocarcinoma of the esophagus or esophagogastric junction underwent surgery after neoadjuvant chemotherapy. Staging was done prospectively with ([18F])FDG-PET/CT, before and after completion of neoadjuvant therapy. Pre- and post-therapy maximal standardized uptake values for the primary tumor (SUV1 and SUV2) were determined, and their relative change (SUV∆%) calculated. Percentage change in SUV1 was compared with histopathologic response (HPR, complete or subtotal histologic remission), disease-free- (DFS) and overall survival (OS). RESULTS: Resection with negative margins was achieved in 60 patients. HPR rate was 14 of 66 (21.2%). Median follow-up was 16 months (range 4-72). For all patients, OS probability at three years was 59% and DFS 50%. In receiver operating characteristics (ROC) analysis, HPR was optimally predicted by a > 67% change in baseline maximal SUV (sensitivity 79% and specificity 75%). In univariate survival analysis (Cox regression proportional hazards), HPR associated with improved DFS (HR 0.208, p = 0.033) but not OS (HR 0.030, p = 0.101), SUV % > 67% associated with improved OS (HR 0.249, p = 0.027) and DFS (HR 0.383, p = 0.040). In a multivariate model (adjusted by age, sex, and ASA score), neither HPR nor SUV∆% > 67% was predictive of improved OS and DFS. However, SUV∆% as a continuous variable was an independent predictor of OS (HR 0.966, p < 0.0001) or DFS (HR 0.973, p < 0.0001). CONCLUSION: Our results support previous results showing that ([18F])FDG-PET/CT can distinguish a group of patients with worse prognosis after neoadjuvant chemotherapy in adenocarcinoma of the esophagus or esophagogastric junction. This information could offer a new independent preoperative marker of prognosis.

[Cardiac sarcoidosis]. / Sydänsarkoidoosi.

Cardiac sarcoidosis is a severe inflammatory disease of the cardiac muscle, manifesting itself as atrioventricular block, ventricular tachycardias, cardiac insufficiency and combinations thereof. Approximately half of cardiac sarcoidosis patients exhibit no clinical signs of sarcoidosis outside the heart. The diagnosis is based on cardiac muscle imaging and myocardial biopsy. High dose corticosteroid medication is utilized for treatment. A life-threatening cardiac event occurred in more than one third of cardiac sarcoidosis patients at Meilahti hospital.

Medialization of paralyzed vocal fold does not increase respiratory resistance measured by impulse oscillometry.

Injection laryngoplasty restores voice in subjects with unilateral vocal fold paralysis, but knowledge of its effects on airflow dynamics is limited. Impulse oscillometry (IOS) is a non-invasive technique to investigate airway resistance. It is easily performed during normal breathing. A prospective study was conducted in order to investigate the effects of autologous fascia injection on airflow dynamics. IOS, flow-volume spirometry, acoustic analysis of voice, voice handicap index (VHI) questionnaire and subjective dyspnoea score were recorded before and 5-11 months after the operation. There was no significant change in respiratory resistance (Rres) or other variables of IOS. FEV1/FVC decreased from 0.80 to 0.77 (P = 0.02), but other variables of spirometry did not change significantly. Acoustic properties of voice (noise-to-harmonics ratio, shimmer, jitter, maximal phonation time) and VHI improved significantly. No change in dyspnoea occurred. In conclusion, medializing of a paralysed vocal fold improves voice, but does not have a clinically significant adverse effect on breathing. Flow-volume spirometry is more sensitive than IOS to changes in airflow dynamics after medialization.
