Economic development as a way to fight against poverty in a coastal society
Authors: Rukin Rukin 
Published: July 2018

This research is based on the phenomenon of low construction in coastal village areas, primarily in relation to the economic development sector. This study was conducted in order to determine the low economic level of coastal rural communities and its abundant natural resources (SDA). The government has already issued a public policy related to economic empowerment and coastal zone management. However, the coastal village community’s economy remains very low. The qualitative and phenomenological approach was used to obtain the findings about why society in coastal villages is economically low level. The main cause of the economic problem was the lack of ability of the public to capture the business opportunities that existed. In addition, the constant hereditary lifestyle of the coastal people is one of the triggers of their low economic power. There is a lack of distinct empowerment by the government in order to improve their economy. SDA has not been optimally empowering coastal areas by way of the village communities of the coast and there is a lack of village infrastructure. The concrete participation of the local government is expected in relation to the handling of economic empowerment. One solution that can be undertaken is the revamping of public policy related to the development of coastal villages. The completion of the installation program for paving and street lighting is also a priority. The development and empowerment of the economy should be done immediately. Another thing that can be done by the government is the optimisation of the religious and beach tourism there.

How Can the International Community Best Respond to the Problem of Child Soldiers?
Authors: Lleshi MA. Astrit 
Published: July 2018

The child soldier phenomenon is not recent and has been manifested throughout centuries; as such the use of children in armed conflicts receives universal condemnation.Currently child soldiers of different age groups are forced to kill and commit other violent acts in many wars and other conflicts around the world; however it is impossible to know their exact numbers.In 1998 The Rome Statute of the International Criminal Court (ICC) has criminalized the use of children in armed conflicts, nevertheless to this day minors are being abused indiscriminately in many armed conflicts around the world. This article argues for the creation, use and application of a single universal definition of what constitutes child soldiering, recognition and protection of children as a vulnerable group in armed conflicts, as well as attempts to put forward ideas how can international community best respond to the problem of the child soldiers.

The purposeof the study was a systematic literature review of imaging assessment of lymph node metastasis in patients with laryngeal and hypopharyngeal cancer.Material and methods.In order to review the most relevant scientific literature available, we searched Elibrary, Medline databases (from January 2005 to December 2017). Of 735 identified studies, 32 were assessed.Results. The role of ultrasonography, spiral computer tomography, magnetic resonance tomography, positron emission tomography in the assessment of regional metastatic spread in patients with laryngeal and hypopharyngeal cancer was analyzed. All these imaging techniques failed to reliably identify clinically occult lymph node metastases. However, the choice of treatment options for laryngeal and hypopharyngeal cancer depends considerably on the diagnostic accuracy. In this context, the concept of sentinel lymph nodes deserves special attention.Conclusion.Further studies of the sentinel lymph node concept using various radiopharmaceutical drugs in the detection of preclinical regional metastasis in patients with laryngeal and hypopharyngeal cancer are required.

Background. Serous cystic pancreatic neoplasm is a rare pancreatic tumor, accounting for 1–2 % of all pancreatic tumors. In 2010, mixed serous neuroendocrine cystic neoplasia was included into the classification of the WHO for pancreatic tumors. Only a few cases of this disease have been reported in the literature. Mixed serous neuroendocrine cystic neoplasia is often associated with von Hippel Lindau disease. Most authors recommend surgery as a main treatment of this disease.Case report. We present a case with mixed serous neuroendocrine cystic neoplasia not associated with von Hippel Lindau disease. The patient underwent spleen – preserving distal pancreas resection. The diagnosis was histologically and immunohistochemically verified. There is no evidence of disease recurrence within 10 months after surgery. Conclusion. Histological examination of the resected serous cystadenoms should take into account the possibility of combining this pathology with pancreatic neuroendocrine tumors. For the purpose of verification, the use of immunohistochemical examination is required. Radical surgical resection allows patients with this disease to be cured.

Purpose.We analyzed the frequency and severity of hematologic, hepatic and pancreatic toxicity during and after completion of neoadjuvant chemoradiotherapy in patients with gastric cancer.Material and methods. Phase II clinical trial was conducted to evaluate the efficacy of the combined modality treatment including neoadjuvant chemoradiotherapy followed by D2 gastrectomy for patients with locally advanced gastric cancer. The main inclusion criteria were: histologically verified gastric cancer, cT3-4N0, cT2-4N1-3; M0. Before starting neoadjuvant therapy, all patients underwent thoracic and abdominal CT and laparoscopy to exclude peritoneal carcinomatosis. A total dose of radiation therapy was 45 Gy (1 + 1.5 Gy/fraction/day with a 4–5 hour interval) concurrently with the modified CAPOX chemotherapy regimen. Gastrectomy or subtotal resection of the stomach was planned 4-6 weeks after the completion of chemoradiotherapy. The toxicity assessment of neoadjuvant chemoradiotherapy was performed using the NCI CTC scale, version 3.0. The assessment of hematological, hepatic and pancreatic toxicities was done.Results.Among the toxicity during and after completion of neoadjuvant chemoradiotherapy, thrombocytopenia, neutropenia and leukopenia (grade 1–2) were the most common, requiring no additional symptomatic therapy. Radiation therapy was completed in 45 (98 %) patients. Chemotherapy was completed in 42 (91 %) patients. The median time between the completion of chemoradiotherapy and surgery was 44 days. Surgery following chemoradiotherapy was performed in 100 % of patients, including R0 resection in 93 % of patients.Conclusion.Preoperative chemoradiotherapy was well tolerated by patients, could be completed in most cases and did not prevent subsequent surgical treatment.

Background.A functionally significant TP53Arg72Pro polymorphism can contribute to the development of gastric cancer (GC).The aim:to study the associations of genotypes and alleles of the TP53Arg72Pro 4 polymorphism with GC and biomarkers of gastric ucosal atrophy in population-based prospective and case-control clinical trials among the population of Siberia.Material and methods.As a part of the epidemiological study, data of the international multicenter HAPIEE project for 2003–05, based on a population sample of residents of Novosibirsk city (serum and DNA samples) and data of the population-based registry of GC (2012) were compared. Gastric cancer patients were matched by age and sex to HAPIEE population controls. A total of 156 serum samples (GC – 52, control – 104) and 146 DNA samples (GC – 50, control – 96) were available for prospective analysis. DNA samples from 80 gastric cancer patients (45 men and 35 women, mean age 61.0 ± 13.4 years) and from 87 age-and sex-matched controls were analyzed. DNA samples from venous blood were genotyped according to standard methods. Serum samples were tested using diagnostic kit for enzyme-linked immunosorbent assays to determine the levels of pepsinogen I (PGI), PGII, PGI/PGII ratio, gastrin-17 and IgG antibodies to H. pylori.Results.No differences in genotype and allele frequencies of the TP53 gene between the case group and the control group were found. A decreased frequency of the Pro allele in female gastric cancer patients compared with controls indicated that the Pro allele is protective against the development of gastric cancer, but this effect was not observed in male patients. No associations of TP53 genotypes with the risk of diffuse or intestinal gastric cancer, as well as with the age and sex of patients were found. A high frequency of genotypes with the Pro allele in patients with stage III–IV gastric cancer indicated the relationship between Arg/Pro TR53 and tumor progression, in particular, the contribution of the minor Pro allele to the unfavorable prognosis. A prospective study showed high risk of reducing the level of pepsinogen for assessing predisposition to gastric cancer.Conclusion.Two case-control studies (population and clinical) conducted in the Western Siberia found no relationship between the TP53Arg72Pro polymorphism and the risk of gastric cancer. However, the TP53 genotype with a rare Pro allele was associated with atrophic gastritis and severity of gastric cancer.

Reconstruction of head and neck defects after surgery for cancer remains challenging. The choice of the reconstruction technique depends on the tumor size and localization, type of the defect, patient’s age, concomitant diseases, and disease prognosis. Surgeons have currently a broad range of material for reconstructive surgery, from free flaps to revascularized flaps. Microsurgical reconstruction has made a revolution in treatment of patients with complex head and neck defects. However, the use of this technique may not be advisable for some patients. The search for new techniques is needed to improve functional and aesthetic results and reduce traumatism without compromising oncologic outcomes. Thirty-six patients underwent surgery with reconstruction using the submental island flap, a new alternative in the reconstruction of various head and neck defects. The graft was taken after making a neck incision for neck lymph node dissection. A few patients develop total and marginal necrosis of the graft. Short- and long-term results showed no worsening of oncologic outcomes in the selected group of patients.
