Abstract
Difficulties with social interaction characterise children with Autism Spectrum Disorders and have a negative impact in their everyday life. Integrating a social-humanoid robot within the standard clinical treatment has been proven promising. The main aim of this randomised controlled study was to evaluate the effectiveness of a robot-assisted psychosocial intervention and the secondary aim was to investigate potential differences between a robot-assisted intervention group and a control group receiving intervention by humans only. The analysis of the results showed that robot-assisted intervention could be beneficial by improving children's psychosocial skills. This improvement was highlighted by neuropsychological testing and parent reporting. Group comparison only presented minimal statistically significant differences. The study underpins the potential of robot-assisted interventions to augment standard care.

Abstract
Human γδ T cells are enriched at the maternal-fetal interface (MFI, decidua basalis) showing a highly differentiated phenotype. However, their functional potential is not well-known and it is not clear whether this decidua-enrichment is associated with specific γδ T cell receptors (TCR) as is observed in mice. Here we addressed these open questions by investigating decidual γδ T cells during early and late gestation, in comparison with paired blood samples, with flow cytometry (cytotoxic mediators, cytokines) and TCR high-throughput sequencing. While decidual γδ T cells expressed less perforin than their counterparts in the blood, they expressed significant more granulysin during early pregnancy. Strikingly, this high granulysin expression was limited to early pregnancy, as it was reduced at term pregnancy. In contrast to this granulysin expression pattern, decidual γδ T cells produced reduced levels of IFNγ and TNFα (compared to paired blood) in early pregnancy that then increased by term pregnancy. TCR repertoire analysis indicated that human decidual γδ T cells are not generated early in life as in the mouse. Despite this, a specific enrichment of the Vγ2 chain in the decidua in early pregnancy was observed that disappeared later onwards, reflecting dynamic changes in the decidual γδ TCR repertoire during human gestation. In conclusion, our data indicate that decidual γδ T cells express a specific and dynamic pattern of cytotoxic mediators, Th1 cytokines and TCR repertoire suggesting an important role for these unconventional T cells in assuring a healthy pregnancy in human.

Abstract
Abstract
Study question
Do double-vitrified embryos have impaired implantation potential compared to embryos vitrified once?
Summary answer
Double-vitrified embryos demonstrated significantly lower percentages of positive β-HCG, clinical pregnancy (CPR) and live birth (LBR) compared to embryos vitrified once.
What is known already
Since vitrification became a core player in ART, many clinics adopted a freeze-all strategy, including vitrification of more than one embryo per vitrification device. Nowadays, the guidelines’ suggestion for single embryo transfers often results in a surplus of good quality embryos post warming which are re-vitrified to avoid embryo wastage. Thus, transfers of double-vitrified embryos have been performed worldwide, leading to successful pregnancies. It remains yet to be answered whether embryos after double vitrification exhibit the same reproductive performance as embryos vitrified once. By now, limited studies including various cryopreservation methods show relatively conflicting results.
Study design, size, duration
This retrospective cohort study was conducted in Embryolab Fertility Clinic, Greece. Assisted reproductive cycles included in the study were performed from January 2015 to December 2020. Both PGT cycles and cryopreserved oocyte cycles were excluded. The mean women age was 32.8 years old (±5.9) in the study group and 33 (±5.9) in the control group. There was no variation in the cryopreservation methods used, since all embryos were cryopreserved by the same vitrification protocol.
Participants/materials, setting, methods
For the present study, 233 embryo transfers of 334 double-vitrified embryos (309 blastocysts/25 cleavage embryos) and 172 transfers of 260 embryos vitrified once (246 blastocysts/14 cleavage) were analyzed to explore the impact of double vitrification on positive β-HCG, CPR, LBR and miscarriage rate. Moreover, the performance of embryos that were cultured for at least 24 hours before re-vitrification was compared to embryos warmed and re-vitrified on the same day, for the same parameters mentioned above.
Main results and the role of chance
All embryos survived vitrification (100% survival rate) in both study and control group. An alpha level of .05 was used for all statistical tests. Results showed that positive β-HCG percentage was significantly lower in the double vitrification group (45.1% for double -vitrified embryos -study group-, 57.0% for embryos vitrified once -control group-, p=.02), as well as CPR (28.3% in study group - 42.4% in control group, p=.003) and LBR (26.6% in study group - 40.4% in control group, p=.004). The miscarriage rate did not significantly differ between two groups (35% in study group - 25% in control group, p=.121). Moreover, positive β-HCG percentage was significantly higher in transfers with embryos that were cultured at least 24 hours before re-vitrification (group A: 48.9%), compared to embryos that were warmed and re-vitrified on the same day (group B: 30.6%, p=.02). Interestingly, although CPR (31% in group A, 18.4% in group B, p=.08), LBR (29.4% in group A, 16.3% in group B, p=.06) and miscarriage rate (35.6% in group A, 33% in group B, p=.87) were not significantly different between these groups, there was a tendency for rates to be higher in group A compared to group B.
Limitations, reasons for caution
This is a retrospective study, including transfers of embryos of different stage (day 2 – day 5). However, the control group was matched to the study group, in terms of embryo stage. The number of previous treatments per couple was not included in the study.
Wider implications of the findings
Although double-vitrified embryos can lead to successful pregnancies, our results showed an adverse effect of double vitrification on embryo reproductive potential. To avoid lower pregnancy rates, culture of embryos until day 5 and cryopreservation of one embryo per vitrification device should be considered.

Abstract
Abstract
Issue
A trusted source of information, the Baby Buddy webapp was co-created with parents and professionals to support the educational role of maternal healthcare providers. However, providers in Cyprus and elsewhere may not actively engage in antenatal education (AE) to make “every contact count”.
Description of Problem
The impact of Public Health digital interventions can be maximized when adopted in care pathways. To define barriers and enablers in behavioural terms complimentary methods were used guided by the COM-B model and related Theoretical Domains Framework: questionnaire survey (N = 49), focus group (N = 11) and round-table workshops (N = 40) among in-training and registered midwives.
Results
Beliefs about the benefits of AE are strong and viewed as a core function of the professional role, yet not supported nor prioritized by current practice. Many problematic areas relate to organizational context, such as weak interprofessional collaboration and lack of policy, protocols and resources. Medicalization of birth and socio-cultural norms are sustaining alienation of the midwife and conditions of power dynamics. AE was perceived as a means to enhance the autonomy of the profession but the phenomenon is complex and also pertains to perceptions and behaviours of service users. There are also issues with procedural knowledge and the need for skill development was identified.
Lessons
As a digital tool, Baby Buddy can enrich the user-provider exchange. However, AE beyond the formal setting of the antenatal class is perceived to be a ‘bad fit' with current practice. Training (e.g. skills strengthening), persuasion (e.g. reflection on professional identity), enablement (e.g. protocols) were identified as promising intervention functions. Modelling was identified as the most promising both in terms of “credible models” for the role itself as well as re-framing the concept of AE not as preparation for childbirth but in the context of shared decision-making.
Key messages
Barriers to being an effective antenatal educator are several, originating from an unsupportive system and wider socio-cultural norms of users and providers. In addition to designing a theory-driven research-informed intervention, the process functioned as a participatory learning experience through collective reflection.

Abstract
Abstract
Background
The study aimed at measuring the prevalence and identifying the risk factors of intimate partner violence in individuals from the LGBT community.
Methods
A total of 180 individuals participated in the study, both male and female, aged 18-60 years, living in the broader area of Athens, Greece. Snowball sampling was applied to identify eligible individuals and social media were employed to recruit them. The questionnaire explored the violence victimization and perpetration in their relationships, the preferred reaction to various forms of violence and the role of childhood victimization in adulthood experiences of violence.
Results
72.8% were homosexual, 26.7% bisexual, 81.7 % were women with a mean age of 25.2 years (6.0 standard deviation). A total of 67.2% were subjected to verbal abuse before the age of 16, 49.4% to physical violence, 6.7% to sexual violence and 46.7% were neglected. The prevalence of violence victimization was higher than the prevalence of violence perpetration (mean 9.81 and 5.92 respectively). Psychological violence was the most common among other forms of violence, both in victimization (psychological 7.34, physical 1.66, sexual 0.81) and perpetration (psychological 4.48, physical 1.26, sexual 0.18). In hypothetical scenarios of psychological violence, the majority of participants preferred separation and discussion about boundaries as strategies to deal with the situation (56.1 and 45.0 respectively), in scenarios of physical violence they primarily preferred separation and secondarily asking a professional advice (73.3 and 20.6, respectively) and in sexual violence they primarily preferred a discussion about boundaries and secondarily separation (69.4% and 31.7% respectively). Experiences of childhood victimization (p=.006), and female gender (p=.002), were found to be associated at a statistically significant level with violent victimization in adulthood.
Conclusions
Further research is necessary to identify groups at risk of victimization.
Key messages
Preventive efforts need to take into account individual sociodemographic and attitudinal characteristics that increase the risk of victimization. Experiences of victimization during childhood are highly associated with victimization in adulthood.

Abstract
BACKGROUND AND PURPOSE The purpose was to investigate our centre's experience on computed-tomography-guided (CT-guided), transforaminal, intrathecal administration of nusinersen in adult subjects with spinal muscular atrophy (SMA) type 2 and severe spinal deformity. METHOD This is a retrospective, single-centre study investigating the feasibility and safety of CT-guided, transforaminal, lumbar puncture for the intrathecal administration of nusinersen (Spinranza®; Biogen; Cambridge, MA, USA) in a cohort of adult subjects with SMA type 2, severe neuromuscular scoliosis and previous spinal surgery. Between January 2019 and October 2019, five male, adult, SMA type 2 subjects were eligible to be treated in our centre with nusinersen. The mean age of the patients was 31 ± 9 years (range 19-43 years). The study's outcome measures were technical success, adverse events and radiation exposure. RESULTS In total, four patients completed the four loading doses, whilst the fifth patient received only one loading dose; two patients also received their first maintenance doses. Overall, 20 consecutive transforaminal, intrathecal treatments were analysed. Technical success was 100% (20/20 intrathecal infusions). No adverse events were documented following the procedures. Mean dose-length product (DLP) value per injection was 665.4 ± 715.5 mGy*cm. Estimated mean effective dose per injection was 12.7 ± 12.9 mSv. Subgroup analysis between the chronologically first 10 versus subsequent 10 procedures demonstrated a clear trend towards less radiation exposure in the latter, although this difference did not reach statistical significance (DLP: 984.7 ± 903.3 vs. 436.7 ± 321.5 mGy*cm, P = 0.165; respectively). CONCLUSIONS In this retrospective series, CT-guided transforaminal access for intrathecal injection of nusinersen was proven feasible and safe. A decrease in radiation dose over time was noted. Protocols to minimize radiation exposure are essential.

Abstract
Abstract
Background
Cardiomyopathy presenting in people living with HIV (PLWHIV) has been attributed to the effect of inflammation, opportunistic infections, myocyte invasion and cardiac steatosis, while peripheral artery disease (PAD) is linked to immune activation, abnormalities in lipid metabolism, and traditional risk factors. The diagnosis of subclinical myocardial dysfunction and PAD could enable prompt implementation of therapeutic measures. However, data available to date on the specific topic are limited.
Μethods:We investigated the association between global longitudinal strain (GLS) and a) patient history, b) baseline characteristics, c) carotid intima-media thickness (IMT) and presence of carotid atheromatic plaque(s) d) temperature difference (ΔT) along each carotid artery, measured by microwave radiometry (MWR) and e) basic blood panel measurements, including high-sensitivity troponin-T(hsTnT) and NT-proBNP in PLWHIV and no history of cardiovascular disease.
Results
We prospectively enrolled forty asymptomatic PLWHIV on long-term highly active antiretroviral therapy. Thirty-seven (93%) were men, while mean age was 52 ± 13 years. Subclinical left ventricular systolic dysfunction(SLVSD), defined as a value of GLS> -18.7%, was present in 35% of patients. GLS value was significantly associated with age (r = 0.410,P = 0.013), history of hyperlipidemia (r = 0.370,P = 0.026), body mass index (r = 0.462,P = 0.005), waist circumference (r = 0.471,P = 0.007) and right bulb IMT (r = 0.390,P = 0.036). hs-TnT levels were significantly associated with age (r = 0.513, P = 0.001), CD4 count (r=-0.357,P = 0.025), serum creatinine (r = 0.338,P = 0.035) and the presence of carotid plaque (r = 0.374,P = 0.038). NT-proBNP levels were significantly associated with history of diabetes (r = 0.336,P = 0.048) and serum creatinine (r = 0.548,P = 0.001).

Abstract
BACKGROUND This study aimed at assessing the effect of previous anesthesia experience on patients' knowledge of anesthesia and the role of anesthesiologists, on what they would want to know about anesthesia and the way they would like to be informed. METHODS Questionnaires with fixed questions were distributed to consenting, consecutive surgical patients before the pre-anesthetic visit. Patients were divided into two groups: patients with previous anesthesia experience (Group A) and patients without previous anesthesia experience (Group B). The questionnaires included patients' demographics, questions related to their knowledge about the anesthesiologists' role and about their desire for information. RESULTS 500 questionnaires were analyzed. The majority of patients (94.2%) know that the anesthesiologist is a specialized doctor and 89.2% believe that the anesthesiologist watches over the patient throughout surgery. These results were similar in both groups. The majority of patients (98.2%) also want to meet the anesthesiologist before surgery and 78% want even more information. Only 65.6% want to be aware of all possible complications, in both groups, while 17.6% do not want to know anything about complications. In general, answers to specific questions regarding what the patients want to know about anesthesia did not differ between groups. The vast majority of patients wish to talk with the anesthesiologist before surgery. CONCLUSION Previous anesthesia experience did not seem to influence patients' desire for meeting the anesthesiologist and seeking information. A strong desire to personally meet the anesthesiologist is expressed and patients' desire for even more information is noted.

Abstract
BACKGROUND Narcolepsy with cataplexy is associated with a loss of orexin/hypocretin. It is speculated that an autoimmune process kills the orexin-producing neurons, but these cells may survive yet fail to produce orexin. OBJECTIVE To examine whether other markers of the orexin neurons are lost in narcolepsy with cataplexy. METHODS We used immunohistochemistry and in situ hybridization to examine the expression of orexin, neuronal activity-regulated pentraxin (NARP), and prodynorphin in hypothalami from five control and two narcoleptic individuals. RESULTS In the control hypothalami, at least 80% of the orexin-producing neurons also contained prodynorphin mRNA and NARP. In the patients with narcolepsy, the number of cells producing these markers was reduced to about 5 to 10% of normal. CONCLUSIONS Narcolepsy with cataplexy is likely caused by a loss of the orexin-producing neurons. In addition, loss of dynorphin and neuronal activity-regulated pentraxin may contribute to the symptoms of narcolepsy.

Abstract
Whipple disease is a relapsing systemic illness caused by Tropheryma whippelii. Central nervous system involvement occurs in 5%-40% of all patients. Hypothalamic manifestations occur in 31% of Whipple encephalopathy, including polydipsia, hyperphagia, change in libido and insomnia. We report a case of a 48-year-old man with severe insomnia, depression, dementia, dysarthria, myoclonic movements of the limbs and ophthalmoplegia. The diagnosis of Whipple encephalopathy was confirmed by PCR analysis of blood and faeces. He received a full dose of antibiotic treatment. Despite clinical improvement, resolution of the lesions detected in MRI scan of the brain and negative results of the PCR in blood, faeces and cerebrospinal fluid six months later, insomnia persisted and finally subsided after the administration of carbamazepine (600 mg/day). Our case supports the finding that carbamazepine might be useful in the treatment of insomnia associated with Whipple encephalopathy.

Abstract
Combined radioimmunotherapy (RAIT) and hypoxic cytotoxin therapy (SR4233 or NLCQ-1) have been evaluated with both modalities administered on the same day with only moderate improvement compared with the effects of RAIT alone. In a series of studies using oxygen electrodes, immunohistochemistry and radiotracers, we have demonstrated that RAIT induces a prolonged state of hypoxia in most tumors, without affecting the pO(2) levels in normal tissues. Using serial microelectrode measurements through subcutaneous (s.c.) GW-39 human colonic xenografts, we established that the median pO(2) was unrelated to the initial size of the tumor, over a range of sizes from 1.0 to 4.0 cm. Fourteen days after mice were given a 240-microCi dose of (131)I-MN-14 anti-carcinoembryonic antigen immunoglobulin G, their median pO(2) declined from 26.1 +/- 9.6 mmHg to 9.8 +/- 3.9 mmHg (p < 0.001). Using the radiotracer (3)H-MISO that accumulates in hypoxic regions, uptake in GW-39, LoVo and LS174T s.c. human colonic tumors increased 3.0- to 4.2-fold from day 14 through day 28 post-RAIT, but uptake of (3)H-MISO in CALU-3 tumors remained unchanged after RAIT. Normal tissue (liver, kidney, lung) uptake of (3)H-MISO did not exhibit significant changes. The increase in tumor hypoxia was also demonstrated visually using anti-PIMO staining of tumor sections. We postulated that sequential delivery of the 2 therapeutic agents, with the hypoxic cytotoxin given 2 weeks after RAIT when tumor pO(2) levels were at their nadir, would improve the therapeutic response above either modality alone or above the 2 agents delivered on the same day. Tumor growth was compared in mice given either RAIT or cytotoxin alone, the combined treatment on the same day or with the cytotoxin delivered 14 days after RAIT. Tumor size on day 35 for RAIT-treated and SR4233-treated GW-39 were 3.56 +/- 0.40 and 7.98 +/- 2.50 cm(3). When RAIT + SR4233 were delivered on the same day, tumor size dropped to 2.78 +/- 0.80 cm(3). If RAIT was given on day 0 and SR4233 on day 14, size further declined further to 1.74 +/- 0.32 cm(3) (p < 0.05 compared with same day delivery). For LS174T, tumor size on day 28 for RAIT-treated and SR4233-treated tumors were 1.14 +/- 0.36 cm(3) and 3.65 +/- 0.78 cm(3), respectively. When RAIT + SR4233 were delivered on the same day, size was 0.51 +/- 0.174 cm(3). If RAIT was dosed on day 0 and SR4233 was given on day 14, tumor size was 0.13 +/- 0.07 cm(3) (p < 0.05). Similar results were obtained for LoVo, but not for CALU-3 tumors. Another hypoxic cytotoxin, NLCQ-1, was also more efficacious 2 weeks after RAIT, compared with same-day dosing. Thus, information on tumor hypoxia after radioantibody therapy could be important for ascertaining a window of opportunity when the surviving tumor regions are most responsive to hypoxic cytotoxins.

Abstract
Pathological changes in the urine sodium dodecyl sulphate gel electrophoresis (SDS PAGE) patterns often precede the occurrence of any sign of renal involvement in diabetes. However, data concerning the most frequent SDS PAGE pattern of the urine in early stages of type I diabetes mellitus are controversial. In the present study an SDS PAGE technique has been used that provides an adequate sensitivity for the detection of the abnormal pattern. Urinary proteins have been analyzed by SDS PAGE in twenty two diabetic adolescents and twenty four age matched controls. Albumin concentration, and N acetyl-beta-D-glucosaminidase (NAG) activity were also measured in the same samples. There was no significant difference in urine albumin concentration and NAG activity between diabetic children and controls. However twelve patients showed an electrophoretic pattern characteristic for glomerulopathy, two had a pattern indicating tubular dysfunction and another two patients had a mixed pattern. Among the twenty four controls only three showed abnormal electrophoretic patterns. The results support the view that early stages of diabetic nephropathy may involve both glomerular and tubular dysfunction. However the exact clinical and prognostic significance of the information provided by SDS PAGE analysis remains to be elucidated.

Abstract
PURPOSE To evaluate the outcome and the prognosis of patients with ovarian germ cell malignancies who were treated with platinum-based chemotherapy immediately after initial surgery. METHODS We conducted a retrospective review of patients with ovarian germ cell tumors who were referred for consideration of treatment to the Departments of Medical Oncology participating in the Hellenic Cooperative Oncology Group. RESULTS Over a 14-year period 53 patients were included in our study. There were 13 patients with dysgerminoma and 40 patients with nondysgerminomatous tumors. Forty percent of patients underwent complete resection of their tumors. Platinum-based chemotherapy consisted primarily of cisplatin, vinblastine, and bleomycin (PVB) in 9 patients; bleomycin, etoposide, and cisplatin (BEP) in 15 patients; and bleomycin, etoposide, and carboplatin (BEC) in 25 patients. With a median follow-up of 39 months, 5 patients developed progressive disease and died of their tumor and 1 patient died of bleomycin-induced lung toxicity with no evidence of active tumor. The 5-year overall survival was 100% for patients with dysgerminoma and 85% for patients with nondysgerminomatous tumors. Eighty percent of patients with advanced nondysgerminomatous tumors and residual disease after surgery remain disease free. CONCLUSION With this study we confirm that patients with ovarian germ cell malignancies have a favorable outcome when treated with platinum-based chemotherapy.

Abstract
A phase II trial was conducted in order to assess the efficacy and toxicity of paclitaxel given at a dose of 175 mg/m2 in a 3-hour infusion every 3 weeks in patients with recurrent or cisplatin (CDDP) carboplatin-refractory ovarian cancer. Forty-two patients with a median age of 61 years (range 34-76 years) entered the study. Most patients had bulky disease. Thirty-three patients (78.5 %) presented with stage III and IV diseases. Twenty-two patients (52.3%) had previously been treated with only 1 regimen and 20 patients (47.7%) with > or = 2 regimens. The median treatment interval from the last previous therapy was 4.5 months (range 2-26 months). From 41 patients evaluable for response, 3 (7.3%) achieved a complete and 4 (9.8%) a partial response. All 3 complete and 2 out of the 4 partial responders had previously received > or = 2 chemotherapeutic regimens. Grade 3-4 toxicities included granulocytopenia (35%), which was of short duration, neurotoxicity (9.75%) and alopecia (60.9%). Two patients with grade 4 neutropenia were hospitalized due to pneumonia, which was successfully treated by broad-spectrum antibiotics and administration of G-CSF. A severe hypersensitivity reaction occurred in 1 patient early during the first cycle, resulting in discontinuation of treatment. Median relapse-free survival was 6.9 months, median time to progression 6.2 months and median survival 13.2 months. In conclusion, paclitaxel given at a dose of 175 mg/m2 as a 3-hour infusion every 3 weeks appears to be an efficacious and well-tolerated treatment in patients with recurrent or CDDP/carboplatin-refractory ovarian cancer.

Abstract
Forty-four patients with either metastatic or locally advanced transitional cell carcinoma of the bladder were treated with the MCNO regimen (methotrexate 300 mg/m2 in 1,000 ml normal saline as a 4-hour infusion on days 1 and 14 with leucovorin rescue 15 mg 6-hourly for 6 doses; carboplatin 300 mg/m2 in 250 ml 5% distilled water as a 1-hour infusion on day 1; mitoxantrone (Novantrone) 10 mg/m2 in 100 ml 5% distilled water as a 30-min infusion on day 1, and vincristine (Oncovin) 1 mg/m2 as an intravenous bolus on days 1 and 14. Patients with metastatic disease were treated with 6 cycles, while patients with locally advanced disease were treated with 4 cycles of induction chemotherapy followed by cystectomy or radiotherapy. The overall response rate was 40%, with 15% complete response (CR). The responses were better for patients with locally advanced disease (CR 25%, partial response, PR, 31.25%, response rate, RR, 56.25%) than for those with metastatic disease (CR 8.3%, PR 20.83%, RR 29.1 %). The differences in these results were probably due to the bad performance status and the presence of visceral metastases in patients with generalized disease. The overall median survival was 14 months, with responders living longer (median survival 28.8 months in patients with locally advanced disease and 22.9 months in patients with metastatic disease) than non-responders (median survival 16 months in patients with locally advanced disease and 8.9 months in patients with metastatic disease). The difference in survival between responders and non-responders was statistically significant in both groups of patients. Toxicity was moderate, but manageable. The MCNO regimen appears to have a lower efficacy than that obtained with cisplatin-based regimens for the treatment of metastatic disease and rather similar efficacy for the treatment of locally advanced urothelial-cell cancer. Therapy with this regimen, though less toxic, may not be a reliable alternative in elderly patients with visceral metastases and a performance status of > or = 2.

Abstract
A prospective phase II trial was carried out to define the activity of a low-dose subcutaneous regimen of interleukin-2 (IL-2) and interferon alpha-2b (IFN-alpha) in combination with intravenous administration of vinblastine (VLB) in patients with metastatic renal cell cancer (RCC). Thirty-one patients with advanced RCC who had received no prior biochemotherapy were treated with IL-2 4.5 MU x 2/24 h thrice weekly for 2 weeks, IFN-alpha 3 MU/24 h thrice weekly (alternating days) for 2 consecutive weeks and VLB 4 mg/m2 every 3 weeks. Patients were to have a 1-week rest period after each 2 weeks of therapy with cytokines. Treatment was repeated every 3 weeks. Maximum duration of treatment was 1 year. Treatment was administered on an outpatient basis. There were 4 complete (12.9%) and 8 partial responses (25.8%), with an overall response rate of 38.7%. The median duration of response was 6.5 months. Responses were seen in lung, lymph nodes, bones, liver and other tumor metastases. Toxicity was mild to moderate, consisting of fever, anorexia, malaise and nausea-vomiting in > 80% of patients. Hypotension and transient alopecia occurred in > 20% of patients. Liver enzyme elevation was frequently observed. Treatment-induced eosinophilia occurred in the majority of patients, while in 52% of patients granulocytopenia grade II and grade III did not require dose modification of drugs. Transient inflammation and local induration at the injection sites was observed in the majority of patients. None of the patients experienced major VLB-related toxicity and no toxic deaths occurred. This three-drug combination immunochemotherapy may be a promising regimen with modest toxicity in advanced RCC.

Abstract
This study was conducted to investigate the clinical utility of CEA, CA 19-9, and CA-50 in the diagnosis, monitoring, and prognosis of 62 gastric carcinoma patients having either adjuvant or palliative chemotherapy. Patients were divided in two groups: group A included patients treated on an adjuvant basis following a curative resection of gastric cancer, and group B included patients with residual disease post surgery or patients with inoperable tumor or generalized disease. Serum marker levels were measured in a prospective study just before the initiation of chemotherapy and before each course during chemotherapy. In group A, CEA was positive in 2/25 (8%) patients, CA 19-9 in 1/25 (4%), and CA-50 in 1/25 (4%). In group B the sensitivity of CEA was 48.6% (18/37 patients), of CA 19-9 64.9% (27/37 patients), and of CA-50 70.3% (26/37) patients. There was a significant correlation between the CA 19-9 and CA-50 levels in both groups. No correlation was found between the sensitivity or the absolute initial marker levels and the tumor's differentiation or extent of disease. In group A the only patient with initially elevated CA 19-9 and CA-50 values relapsed early while he was on adjuvant chemotherapy. It was also found that the rising final CA 19-9 and CA-50 values at the end of chemotherapy were correlated with an increased incidence of relapse, but not with the disease-free interval. In group B the initially low marker levels showed a trend to predict a favorable outcome of treatment. There was no statistically significant correlation between the marker titers before each course and response to chemotherapy. It is concluded that the comeasurement of CA 19-9 and CA-50, and to some degree of CEA, is justifiable for gastric cancer. The estimation of CA 19-9 and CA-50 may be useful for early detection of recurrence after curative surgery and adjuvant chemotherapy. In advanced or recurrent gastric cancer, the estimation of either CA 19-9 or CA-50 and CEA serum values may help in checking the prognosis, determining the efficacy of palliative treatment modalities, and recognizing recurrences.

Abstract
UNLABELLED Growth hormone (GH) secretion was determined by evaluating circadian GH profiles for 24 h and GH responses to clonidine stimulation test and insulin-stimulated hypoglycaemia (ITT), in nine prepubertal children with beta-thalassaemia major (TM) and 17 with non-GH deficient short stature (NGHDSS). The TM children were multitransfused and had early and intensive chelation therapy. All patients had normal hypoglycaemia to ITT, with peak GH levels of 15.71 +/- 5.86 ng/ml for children with NGHDSS and 13.91 +/- 7.20 ng/ml for children with TM. Peak GH levels during a clonidine test were 17.54 +/- 5.30 and 17.15 +/- 1.38 ng/ml, respectively. The GH peak parameters such as the number of peaks, the integrated GH concentration and the area under the curve (AUC) were similar in both groups of children and reflected the total 24-h secretion and the daily and nocturnal secretion separately. An abnormal 24-h GH profile compatible with the diagnosis of endogenous neurosecretory GH dysfunction was found in only two out of nine children with TM and in four out of seven children with NGHDSS. CONCLUSION Our data suggest that growth hormone neurosecretory dysfunction is not a universal finding in children with thalassaemia major but might depend on the degree of iron deposit in the pituitary.

Abstract
Early in the course of a painful crisis, a 19-year-old man with known sickle cell anemia (SCA) developed a clinical picture that resembled either early cavernous sinus thrombosis or retroorbital and bifrontal microinfarcts. A brain computer tomography scan demonstrated bilateral retroorbital hemorrhages along with a left frontal epidural hematoma. In the absence of trauma, thrombocytopenia, or any other detectable hemostatic defect, this type of hemorrhagic manifestation in the setting of SCA has not, to our knowledge, been previously reported in the literature.

Abstract
Haematological and clinical characteristics have been examined in 30 patients with homozygous sickle cell (SS) disease, 28 with sickle cell-beta zero thalassaemia, and 21 with sickle cell-beta+ thalassaemia. The latter could be divided into three groups on their molecular basis and HbA levels, four subjects with an IVS-2 nt 745 mutation having 3-6% HbA (designated S beta+ thalassaemia type I), 14 subjects with an IVS-1 nt 110 mutation having 8-15% HbA (designated S beta+ thalassaemia type II), and three subjects with an IVS-1 nt 6 mutation having 20-25% HbA (designated S beta+ thalassaemia type III). Comparisons were conducted between SS disease, S beta zero thalassaemia, and S beta+ thalassaemia type II. Compared to SS disease, both thalassaemia syndromes had higher HbA2 levels and red cell counts and lower mean cell haemoglobin content (MCHC), mean cell volume (MCV) and MCH, and S beta zero thalassaemia had higher HbF and reticulocyte counts. Compared to S beta zero thalassaemia, S beta+ thalassaemia had a higher haemoglobin and MCHC. Clinically, persistence of splenomegaly was more common in S beta zero and S beta+ thalassaemia type II compared to SS disease. Few significant differences occurred between SS disease, S beta zero and S beta+ thalassaemia type II in Northern Greece suggesting that the 8-15% HbA in the latter condition was insufficient to modify the clinical course.

Abstract
The clinical and haematological features of homozygous sickle cell (SS) disease were compared in 30 Greek and 310 Jamacian patients. Deletional alpha-thalassaemia, which modifies SS disease, is rare among Greek patients, so only Jamacian patients with four alpha-globin genes were included in the control group. Greek patients had higher total haemoglobin concentration and red cell counts, and lower mean cell haemoglobin concentration (MCHC) and reticulocyte counts. They also had a more normal body build and more adults had persistent splenomegaly. Fewer had a history of leg ulceration or priapism but more reported acute chest syndrome. The comparatively mild disease in Greek patients is consistent with less haemolysis and sickling and therefore less bone marrow expansion. In the absence of amelioriating factors such as high HbF concentration or alpha-thalassaemia, these findings may be explained by the low MCHC.
