John C. Carapanayiotis (1909-1999): the Greek radiologist and pioneer of physiatry in Greece

John C. Carapanayiotis was specialized in physical medicine and rehabilitation in the USA in 1948, at a time when the medical world in post-war Greece was ignorant of this specific medical specialty, and the political, economic and social backdrop was incapable of accepting and understanding the wealth of scientific knowledge that he was trying to introduce. At this point it should be noted that the specialty of Physical Medicine and Rehabilitation was established in Greece in 1973. John C. Carapanayiotis was a member of the American Congress of Physical Medicine during the 1950's. In the same period, he expressed interest, on behalf of the New York University, in the establishment of a Physical Therapy Clinic in Greece, which would be granted unlimited funding by the Marshal Plan. His efforts clashed constantly with the backward mentality of his time, with the entrenched conservatism and with the bureaucratic red tape. Unfortunately, he was far ahead of his time and was condemned to the same fate as all other visionaries and pioneers in the way that his knowledge and scientific background were not put into practice for decades to come.

Implementing a system to evaluate quality assurance in rehabilitation in Greece.

BACKGROUND: Use of a widely accepted quality assurance tool is an essential procedure of effective and result-oriented quality management in the rehabilitation sector, and generally in health care and social services, but is still lacking in Greece. OBJECTIVE: This study aims to explore to what extent a Quality Assurance System in Rehabilitation (QASR) in the Greek setting could respond to the needs for quality evaluation of the facilities for people with a disability and to discuss possibilities of its use in rehabilitation organizations, sites and hospitals. METHODS: The European Quality in Social Services (EQUASS) Assurance self-assessment questionnaire was officially translated and used as the basis for the new tool, which consisted of 110 questions in 11 sections on development and 6 questions on its evaluation. This tool was tested in 15 specialized centers. RESULTS: The study received a high (93.75%) response rate. Overall score ranged from 11% to one perfect 100%; 53.3% of the facilities fell short of the preset qualification standards, while 4 (26.7%) were qualified for level-1 accreditation. Evaluation of the QASR questionnaire for the function of the rehabilitation facilities for the disabled was extremely positive. CONCLUSIONS: The EQUASS assurance-based Greek QASR has received proper attention in its first implementation and it was shown promising to assess the needs of sites that would like to improve their services. The next steps are to establish its validity and reliability so that it can significantly emerge as the standard system for guiding policy in the rehabilitation sector in Greece.

Quality assessment systems in rehabilitation services for people with a disability in Greece: a critical review.

BACKGROUND: Despite international interest on quality assessment systems (QAS) and their importance in health care accreditation, implementation of a Rehabilitation Services Quality Measurement System still remains a neglected subject in Greece. OBJECTIVE: To identify appropriate tools for researchers and policy makers to assess the quality of rehabilitation services in Greece, within the current active debate on national health care reform. METHODS: A critical review methodology was undertaken, using a systematic approach, aiming to identify the most appropriate tools in the field. Multi-step strategy was followed to gather relevant data, including bibliographical database, internet and hand searches. RESULTS: Twenty-two studies, articles and documents were identified as meeting all inclusion criteria, representing four QAS, compared according to appropriateness, efficiency, and feasibility for general use. The European Quality in Social Services (EQUASS) was evaluated as meeting all of the desired features, such as proper certification, objective measuring, equality, education and training, established guidelines and person-centered approach. CONCLUSIONS: EQUASS initiative, developed according to European standards and implemented in resource-limited settings, was recognized as the most adaptive and appropriate system for Greek rehabilitation settings. Health policy makers are urged to take findings into consideration in establishing an integrated, quality-assured rehabilitation system throughout the country.

Anatomic variations of the right hepatic duct: results and surgical implications from a cadaveric study.

Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency. Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior segmental branches, the way they form the right hepatic duct, and the main variations of their drainage pattern. Results. The anatomy of the right hepatic duct was typical in 65.75% of samples. Ectopic drainage of the right anterior duct into the common hepatic duct was found in 15.07% and triple confluence in 9.59%. Ectopic drainage of the right posterior duct into the common hepatic duct was discovered in 2.74% and ectopic drainage of the right posterior duct into the left hepatic duct in 4.11%. Ectopic drainage of the right anterior duct into the left hepatic ductal system and ectopic drainage of the right posterior duct into the cystic duct was found in 1.37%. Conclusion. The branching pattern of the right hepatic duct was atypical in 34.25% of cases. Thus, knowledge of the anatomical variations of the extrahepatic bile ducts is important in many surgical cases.

Hypoxia upregulates the expression of the O-linked N-acetylglucosamine containing epitope H in human ependymal cells.

Epitope H contains an O-linked N-acetylglucosamine (O-GlcNAc) residue in a specific conformation and/or environment recognized by mouse IgM monoclonal antibody H (mabH). Epitope H is present in several types of cells and in several polypeptides outside the CNS. Previous results have shown that in the adult human brains, epitope H is confined mostly to a minority of fibrous astrocytes, and it is greatly upregulated in the reactive astrocytes. Post-translational modification with O-GlcNAc occurs on many proteins involved in several cell processes, such as cell cycle progression, apoptosis, proteasome degradation pathways, and modulation of cellular function in response to nutrition and stress. Hypoxia is one of the major causes of cellular stress. Therefore, in this study, we used the mAbH and the indirect immunoperoxidase method to investigate the expression of epitope H in ependymal cells in brains of persons who died with signs of hypoxic encephalopathy. The results of the present study showed that practically all ependymal cells showed cytoplasmic staining for epitope H in supranuclear cytoplasm in the brain of two premature neonates and in ten infants who died with signs of hypoxic encephalopathy. However, the overwhelming majority of ependymal cells of the nine human embryos taken from legal abortions, ranging from 26 days until 13 weeks of gestational age, and of the ten infants' brains without any sign of hypoxic encephalopathy remained negative. Only occasionally did the ependymal cells show weak cytoplasmic staining in some foci. In addition, the reactive astrocytes in the hypoxic brains showed strong cytoplasmic staining, confirming previous results.

Congenital fusion of the thalami (atresia of the third ventricle) associated with parietooccipital meningocele.

In this article we present a case of a male newborn with a CNS malformation that is characterized mainly by complete fusion of the thalami resulting in atresia of the 3rd ventricle accompanied by fusion of the anterior peduncles of the fornix, the presence of a single occult interventricular foramen lying at the midline, absence of the septum pellucidum, hypoplasia of the corpus callosum, disorganization of the head of the left caudate nucleus, and greatly dilated lateral ventricles (hydrocephalus). The patient underwent surgical correction of the meningocele on his 4th postnatal day. On his 13th postnatal day he had projectile vomiting due to a left parietooccipital hygroma that was drained via a shunt. On his 31st postnatal day he developed seizures and marked dilatation of the lateral ventricles, for which he underwent a ventriculoperitoneal shunt (Brown). On the 14th postoperative day the patient developed aspiration pneumonia and died.

Expression of the O-linked N-acetylglucosamine containing epitope H in normal myometrium and uterine smooth muscle cell tumors.

Epitope H contains an O-linked N-acetylglucosamine (O-GlcNAc) residue in a specific conformation and/or environment recognized by monoclonal antibody H (mAbH). We have previously shown that epitope H is present in more than one polypeptide and in various types of normal and pathological cells. In the present study, we focused on uterine smooth muscle cell tumors and their adjacent normal myometrium to gain further insight into the expression patterns of epitope H in human tissues. The indirect immunoperoxidase method was applied using the mAbH and the monoclonal anti-cytokeratin 8 antibody (AbCK8) in 50 cases of typical uterine leiomyomas and in five cases of uterine leiomyosarcomas, with four cases belonging to Group II A and one to Group III according to Bell et al. [6]. Western immunoblotting was applied using mAbH and AbCK8 in five cases of uterine leiomyomas and their adjacent myometrium. The main results were as follows: (1) epitope H showed intense immunohistochemical expression in 46% (23/50) and moderate expression in 54% (27/50) of uterine leiomyomas, (2) epitope H showed intense immunohistochemical expression in 40% (2/5) and moderate expression in 60% (3/5) of uterine leiomyosarcomas, (3) epitope H showed no difference in the immunohistochemical expression between leiomyomas and their adjacent myometrium and between leiomyosarcomas and their adjacent myometrium, (4) immunohistochemical expression of cytokeratin 8 was not detected in the normal and neoplastic smooth muscle cells, (5) Western immunoblotting showed that in the smooth muscle cells of the myometrium and leiomyomas, epitope H is localized in four polypeptides with molecular weights of 100, 61, 59, and 54 kDa, and (6) Western immunoblotting did not detect cytokeratin 8 in the normal and neoplastic smooth muscle cells. The present results indicate fluctuations of the epitope expression levels in uterine smooth muscle cell tumors and their adjacent myometrium. These fluctuations may be of interest for gaining insight into the pathogenesis of uterine smooth muscle cell tumors, since O-GlcNAc glycosylation is involved in cell cycle and apoptosis pathways and may modify proteins involved in oncogenesis (tumor suppressor proteins and oncoproteins) and proteins with important biological functions such as cytoskeletal proteins, transcription factors, and heat-shock proteins. Furthermore, the present results indicate that cytokeratin 8, without being present in the cells of the myometrium, leiomyomas and leiomyosarcomas, shares its epitope H, which contains its unique sugar O-N-acetylglucosamine residue, with four other unrelated polypeptides produced by the normal and neoplastic smooth muscle cells. This should be considered when using anti-cytokeratin 8 antibodies in immunohistochemistry against smooth muscle cell tumors to avoid false positive immunohistochemical results.

Mental distress and sociodemographic variables: a study of Greek warship personnel.

BACKGROUND: Mental disorders have been found to be the main cause of maladjustment and early discharge of the personnel in the Hellenic Navy and the armed forces in general. This study investigates the mental health status of a warship's military personnel by use of a widely used self-administered scale. METHODS: The 28-item Greek version of the General Health Questionnaire was administered to 281 men aboard a Greek warship to determine their mental health status and to examine possible associations with sociodemographic variables (rank, educational level, marital status). RESULTS: A high prevalence of General Health questionnaire cases (48.8%) was found which indicated conscripts as the group with the greater tendency for problems of adjustment and performance among the personnel of the warship. A negative association was found between educational level and psychological distress, whereas married subjects were found to have better levels of psychological well-being as defined by lower General Health questionnaire scores, compared with unmarried subjects. CONCLUSIONS: Although a further methodological and more sophisticated inquiry is necessary, the findings of the present study could be useful for the design of mental health interventions in the naval and the military setting.
