Abstract Recently, the Polish Navy has extended its capability for the implementation of underwater works with autonomous dives conducted beyond the saturation zone to a depth of 80 mH2O. In the near future it is also planned to introduce long-term dives within typical depths of the saturation plateau. One of the activities resulting from the analysis of the risk associated with the extension of these competences is the need to conduct a critical review of the system for securing hyperbaric treatment of cases of decompression sickness1.

The health related risk of wastewater reclamation and reuse is usually defined by laws, rules or regulations by using only biological tools; i.e. bacteria, viruses, or other pathogens or indicators determination. Those determinations exert some influence in the costs of the mentioned practices, and it seems probable that in the near future more determinations will be required. Nevertheless, a total indication of wastewater biological quality is not given by such organisms; in fact, long-term toxicity is not detected by such means. The future of biological control of reclamation and reuse systems and the price associated to such determinations is examined through a practical application case.

Syrian crisis resulted in at least 6.1 million externally displaced people 983,876 of whom are in Europe while the rest are in neighbouring countries in the region. Turkey, due to its geographical proximity and substantial land borders with the country, has been the most popular destination for those fleeing Syria since April 2011. Especially after 2012, a sharp increase in the number of Syrian refugees arriving in Turkey was witnessed. This has triggered an exponential growth in academic and public interest in Syrian population. Numerous reports mostly based on non-representative sample surveys have been disseminated whilst authoritative robust analyses remained absent. This study aims to fill this gap by offering a comprehensive demographic analysis of the Syrian population. We focus on the demographic differences (from 1950s to 2015) and demographic trends (from 2015 to 2100) in medium to long term, based on data from World Population Prospects (WPP). We offer a comparative picture to underline potential changes and convergences between populations in Syria, Turkey, Germany, and the United Kingdom. We frame our discussion here with reference to the demographic transition theory to help understanding the implications for movers and non-movers in receiving countries in the near future.

Venous Gas Embolism

Gas can enter arteries (arterial gas embolism, AGE) due to alveolar-capillary disruption (caused by pulmonary over-pressurization, e.g. breath-hold ascent by divers) or veins (venous gas embolism, VGE) as a result of tissue bubble formation due to decompression (diving, altitude exposure) or during certain surgical procedures where capillary hydrostatic pressure at the incision site is subatmospheric. Both AGE and VGE can be caused by iatrogenic gas injection. AGE usually produces stroke-like manifestations, such as impaired consciousness, confusion, seizures and focal neurological deficits. Small amounts of VGE are often tolerated due to filtration by pulmonary capillaries; however VGE can cause pulmonary edema, cardiac “vapor lock” and AGE due to transpulmonary passage or right-to-left shunt through a patient foramen ovale. Intravascular gas can cause arterial obstruction or endothelial damage and secondary vasospasm and capillary leak. Vascular gas is frequently not visible with radiographic imaging, which should not be used to exclude the diagnosis of AGE. Isolated VGE usually requires no treatment; AGE treatment is similar to decompression sickness (DCS), with first aid oxygen then hyperbaric oxygen. Although cerebral AGE (CAGE) often causes intracranial hypertension, animal studies have failed to demonstrate a benefit of induced hypocapnia. An evidence-based review of adjunctive therapies is presented.

Abstract Background Although cancer occurrence following surgery for biliary atresia has gradually increased, the development of cholangiocarcinoma in a native liver survivor of biliary atresia is extremely rare. Case presentation A 3-month-old female patient with the correctable type of biliary atresia underwent a cystoduodenostomy. At 16 years of age, she underwent multiple surgeries including lysis of intestinal adhesions, ileostomy, and gastrojejunostomy at another hospital. At 54 years of age, she underwent lithotomy at the porta hepatis, resection of the residual cystic bile duct with gallbladder, and hepaticojejunostomy in Roux-en-Y fashion. As she approached the age of 63, her computed tomography scan showed no liver tumors. In the following year, she developed cholangiocarcinoma at the porta hepatis and underwent chemotherapy. However, the cancer progressed, and she died before she reached the age of 64 years. Conclusions Cholangiocarcinoma is extremely rare in patients with biliary atresia. However, physicians should follow up patients with biliary atresia as closely as possible, as malignant tumors secondary to biliary atresia may increase in number in the near future because of the growing number of long-term survivors with biliary atresia.

Pregnant Diabetic

Major progress has been made in the knowledge and management of diabetes and pregnancy. However diabetes in pregnancy remains an important medical complication, with implications for mother and child in both the short and the long term. There are still controversies concerning the diagnostic criteria of gestational diabetes and concerning the best strategry for the treatment of this disorder. There is even less agreement about whether gestational diabetes is a pathological condition. The perinatal mortality in gestational diabetes has recently become as low as that in the general population. This has led to the conclusion that gestational diabetes is no more than a variant of metabolic adaptation during pregnancy. However, fetal hyperinsulinism is present in gestational diabetes, resulting in macrosomia, neonatal complications and most probably long term consequences. Improvements in the care of the preexisting insulin-dependent pregnant diabetic have been achieved but further progress in understanding the underlying mechanisms and in preventing and treating the disease are important goals for the near future.

Therapeutic Camping

The wilderness camp has been described as a particularly good setting for treatment of the emotionally disturbed child. This article summarizes the current literature on therapeutic camping, including the nature of existing programs, rationales for the superiority of camping as a therapeutic program, and evaluation of existing programs. The results of program evaluation research reported in the literature provide only minimal support for any particular effectiveness ascribed to therapeutic camping in terms of either short term or long term therapeutic outcome. This is seen to be largely due to inadequate investigation of the process and/or the outcome of therapeutic camping.

Acute Graft

Abstract Over the past 5 years, many novel approaches to early diagnosis, prevention, and treatment of acute graft-versus-host disease (aGVHD) have been translated from the bench to the bedside. In this review, we highlight recent discoveries in the context of current aGVHD care. The most significant innovations that have already reached the clinic are prophylaxis strategies based upon a refinement of our understanding of key sensors, effectors, suppressors of the immune alloreactive response, and the resultant tissue damage from the aGVHD inflammatory cascade. In the near future, aGVHD prevention and treatment will likely involve multiple modalities, including small molecules regulating immunologic checkpoints, enhancement of suppressor cytokines and cellular subsets, modulation of the microbiota, graft manipulation, and other donor-based prophylaxis strategies. Despite long-term efforts, major challenges in treatment of established aGVHD still remain. Resolution of inflammation and facilitation of rapid immune reconstitution in those with only a limited response to corticosteroids is a research arena that remains rife with opportunity and urgent clinical need.

Spinal Cord Decompression

Medical personnel in hyperbaric treatment centres are at occupational risk for decompression sickness (DCS) while attending patients inside the multiplace hyperbaric chamber (MHC). A 51-year-old male hyperbaric physician, also an experienced diver, was working as an inside attendant during a standard hyperbaric oxygen therapy (HBOT) session (70 minutes at 253.3 kPa [2.5 atmospheres absolute, 15 metres’ seawater equivalent]) in a large walk-in MHC. Within 10 minutes after the end of the session, symptoms of spinal DCS occurred. Recompression started within 90 minutes with an infusion of lignocaine and hydration. All neurological symptoms resolved within 10 minutes breathing 100% oxygen at 283.6 kPa (2.8 atmospheres absolute) and a standard US Navy Treatment Table 6 was completed. He returned to regular hyperbaric work after four weeks of avoiding hyperbaric exposures. Transoesophageal echocardiography with a bubble study was performed 18 months after the event without any sign of a persistent (patent) foramen ovale. Any hyperbaric exposure, even within no-decompression limits, is an essential occupational risk for decompression sickness in internal hyperbaric attendants, especially considering the additional risk factors typical for medical personnel (age, dehydration, tiredness, non-optimal physical capabilities and frequent problems with the lower back).

The treatment of Parkinson's disease today is complex, time-consuming, but rewarding. The introduction of levodopa has not cured the disease, but has provided the most powerful therapy available yet. Its use is limited by side effects and careful titration to optimum dosage, often in combination with other drugs, is required. Despite best therapy, some patients never respond, and others begin to lose benefit after some years of therapy. New problems, such as the ‘on-off’ effect have appeared with long-term treatment, and require careful adjustment of dosage. As with any replacement therapy, a balance between sub-optimal benefit and side effects has to be discovered and maintained by careful and frequent review. New approaches to treatment may offer further improvement in the near future.

The clinical assessment and management of suicide risk depends primarily on face to face contact with the individual who presents the risk, and aims to predict behaviour in the very near future. Whether or not clinical intervention prevents suicide depends a great deal on the clinician's skill in reaching out to the individual patient. This poses a dilemma, because much of what has been written about predicting suicide has been based on averaged data concerning long-term outcome in large cohorts of patients.
