Ear-lobe anthropometric signs do not relate to longevity. Ear length relates to age.

Dear Editor, During the last 30 years we are collecting various photographs which showed the face of persons who died at various ages during their lifetime. We so collected more than 235 photographs. After strict selection of these photographs, so that we could see well the ear and the ear-lobe we chose 57 of them and studied the following parameters: the vertical length of the ear till the lobe, the vertical length of the earlobe, the total ear length, the width of the ear-lobe and the area of the lobe, in order to relate them to longevity.

Circulatory system and neurosciences. Some perspectives in diagnosis and treatment.

This paper aims to describe how radial artery obstruction can support blood circulation in an ischemic area. A dramatic case is described. Furthermore aims to describe that fatigue, atherosclerosis and toxic substances like in alcoholism may reduce blood flow and energy supply in the cortex and other brain areas and thus unconsciously modify our usual civilized behavior.

Changes in esophageal mucosal morphology and in growth of breast feeding rats fed with milk of low or high temperature.

Dear Editor, This rather original investigation was performed some time ago but is still unpublished. Its aim was to estimate the effect of low or high temperature cow's milk given to breast feeding rats in order to study possible influence of this diet to rats, to their physical growth and also esophageal mucosal pathology. Ten white female Wistar rats, 20 days of age were separated from their mothers and divided in 2 groups of 5 members each.

About an energy functioning by fusion, independently.

An innovative biological energy has been observed related to the eye sight and fusing with another energy over tap water through a small metallic chain. The fused energy has been repeatedly described under standard conditions and it is characteristics vary according to the condition of the eye sight and the water content. This energy may be called: "EFI" (energy functioning, by fusion, independently).

Endless research II. The genomic era. Neohippocratic Medicine.

The great progress of genetics research, during 2015-2017, will certainly influence all medical specialties including nuclear medicine. In nuclear medicine there are still problems to solve as to differentiate between infection, inflammation and cancer etc. Furthermore, in dosimetry and radiation protection there are worldwide problems.

Cauda equina syndrome. An emergency, some unexpected severe symptoms and conservative treatment.

An 83 years old physician, doing only office work and no exercise, presented with cauda equine, due to a large intervertebral disk hernia between L1-L2 vertebrae, after an unorthodox movement. He also had a facet syndrome, a muscular spasm in the gluteus, a small fracture in the periphery of the body of the L2 vertebra and pain in the L4-L5, due to a previous vertebral hernia five years ago. All L1-L5 left lateral area was painful.

An endless research for 2016.

In a moment of reflection of the past year of 2015, as to what we have achieved in medical research and what we need to do in the future we realize that although we have performed an enormous progress in medical research in the past we still have to do much more. In nuclear medicine there are many problems to solve like, how can we differentiate between infection, inflammation and cancer or between lymphomas and adenocarcinomas. In bone scans we need to differentiate traumatic lesions acute or chronic and lesions from another origin.

Morning and night gastric emptying half-time differed more than 220% in two young healthy adults.

Objective: It is important to know normal GEHT of a specific meal taken at specific hours and at specific physical and biological conditions in order to better evaluate abnormal GEHT. It seems that it is more specific to study as we have done in the present paper GEHT in the same individual of a certain meal administered at two different hours, i.e.

Medical deontology, meetings, journals, candidacy for higher posts and how to better enjoy life.

Unfortunately, today few physicians care about medical deontology and medical ethics, that is how to behave and respect others when exercising our medical profession. Some of us may not show the care and kindness we should show towards our students or the due respect to our senior colleagues. Occasionally, when examining our patients we may not pay the proper attention to their problems, being tired from work overload.

Medical Deontology towards medical students, our colleagues and our patients. About meetings, medical journals, candidacy for higher posts and the "silent" society.

Unfortunately, today very few care about medical deontology-ethics that is about how to behave and respect others when we exercise our medical duties. Perhaps we do not show our real care and kind leadership to our students. We do not very much respect our medical colleagues.

Diagnosing atherosclerosis makes Nuclear Medicine a tissue imaging modality.

Atherosclerosis can be identified by fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and is associated with cardiovascular events and all-cause mortality. Inflammation and classification appear jointly in the formation of atherogenesis. Arterial calcification has been also determined by CT, by (18)F-FDG PET and also in the last few years by (18)F-sodium fluoride (NaF) PET.

Errors inducing radiation overdoses.

There is no doubt that equipments exposing radiation and used for therapeutic purposes should be often checked for possibly administering radiation overdoses to the patients. Technologists, radiation safety officers, radiologists, medical physicists, healthcare providers and administration should take proper care on this issue. "We must be beneficial and not harmful to the patients", according to the Hippocratic doctrine.

Acute radiation syndrome and chronic radiation syndrome.

Acute radiation syndrome (ARS) or sickness or poisoning or toxicity is induced after a whole body exposure of men to high doses of radiation between 1-12Gy. First symptoms are from the gastrointestinal system, which together with bone marrow are the most sensitive parts of our body. Chronic radiation syndrome (CRS) may be induced by smaller than 1Gy radiation doses or after a mild form of ARS.

Prostatic specific antigen and bone scan in the diagnosis and follow-up of prostate cancer. Can diagnostic significance of PSA be increased?

Prostate cancer (PC) is currently the most frequently diagnosed cancer in males and constitutes a major health issue in developed countries. On the other hand, the majority of PC cases are considered clinically not significant and certainly not lethal. These discrepancies highlight the need for the early detection of especially those cases that have aggressive features and call for early and radical intervention.

[Medical behavior (deontology) towards our students, our colleagues, our patients and the society].

In this paper we try to describe the importance of a dignified behavior of the physician to his students, colleagues, patients and the society. We come to the conclusion that even if the other party is not showing the best of behavior, the physician has not only the responsibility and the duty but it is very much for his own interest to show a dignified and useful behavior to others. This is the main route for having a good reputation which will help him better exercise his medical duties and offer him personal happiness.

Can we increase our life span? The role of nuclear gerontology.

Elderly people, those above 60 or 65 years old differ from younger people in many ways. Nuclear medicine can play a role in the diagnosis of diseases of the elderly and thus help, in social adjustment and in care for the elderly people. The question is why adult stem cells have a certain limit of reproduction, since their DNA in a normal physical environment can theoretically live very much longer.

Medical radiation exposure and accidents. Dosimetry and radiation protection. Do we only benefit the patient?

This article presents and discusses new information on the old Hippocratic moto of "...

Furosemide for the diagnosis of complete or partial ureteropelvic junction obstruction.

Facticious accumulation of the radiopharmaceutical in the urinary draining system as shown by routine renal tests, like technetium- 99m-diethylenetriamine pentacetic acid, technetium-99m-mercaptylacetyltriglycine or technetium-99m-glucoheptonate renograms can be re-evaluated by administering a diuretic, like furosemide (FS) and obtaining post FS dynamic and static images. Urinary tract obstruction can thus be identified. Partial urinary tract obstruction, the effectiveness of stenting, the effectiveness of obstruction correcting surgery and retroperitoneal lymph nodes, may be diagnosed after FS induced diuresis.

Highlights and prizes of an international meeting.

A short description selected from the presentations which had been awarded prizes in the 4th International Meeting of Nuclear Medicine, of the Hellenic Society of Nuclear Medicine, in Thessaloniki, Greece, is as follows: Professor L.G. Strauss from Heidelberg received the first prize for his original paper under the title: "Modulation of FDG kinetics in tumors by gene expression".

Useful known and unknown views of the father of modern medicine, Hippocrates and his teacher Democritus.

Hippocrates is considered to be the father of modern medicine because in his books, which are more than 70. He described in a scientific manner, many diseases and their treatment after detailed observation. He lived about 2400 years ago.

[Indications and instructions to patients for a positron emission tomography-PET scan. The importance of the hybridic PET/CT-computerised tomography scan and which specialty should be responsible for its function].

Indications and instructions to patients for performing a positron emission tomography - PET scan are mentioned. Although PET camera was developed in 1970 its clinical indications were established in about 1998. The hybridic PET/CT- computerized tomography scanner appeared in 2001 and its clinical indications are still under discussion.

Is hybridic positron emission tomography/computerized tomography the only option? The future of nuclear medicine and molecular imaging.

As we all know, Nuclear Medicine is the medical science using nuclear radiation for diagnosis, treatment and research. Nuclear Medicine, in contrast to Radiology, makes use of unsealed sources of radiation. Nuclear Medicine a few years ago has partly offered Nuclear Cardiology, the most lucrative of all Nuclear Medicine "children" at that time, to Cardiology.

Editor and authors' psychology and the chance of teaching.

It is the duty of the editor to communicate with the authors who submit their scientific work for publication. The question arises as to the best way to perform this communication. The goal is to publish papers that would make their authors proud and the readers of the journal, satisfied.
