AbstractWe report a unique and well-documented case of a type II decompression sickness (DCS) with a latency interval of 70 hours. It may raise divers’ awareness and help medical practitioners to keep suspect divers under close observation longer than before and identify and treat DCS accordingly.

Diving Accidents

Scuba diving has become a popular sport resulting in an increased incidence of diving accidents. A survey done by the United States Navy from 1955 to 1960 revealed that decompression sickness (D.C.S.) is the most common serious complication experienced by scuba divers and the third most likely cause of death. The major cause is drowning and the second is arterial gas embolism from pulmonary barotrauma.D.C.S. has been classified into two groups. Type I includes the less severe forms with bubbles in the skin (“itches”), joints and other tissues. Type II includes the serious conditions with neurological involvement “staggers.” A detailed knowledge of D.C.S., commonly known as “the bends,” is essential to both divers and emergency personnel in order to minimize the morbidity and mortality associated with this condition.A case of Type II bends with spinal cord damage is presented and the condition discussed.

Hospital Days

Dural Arteriovenous Fistulas (dAVF) are pathological shunts that are often idiopathic in presentation. However, it is reported that many patients presenting with dAVF have past medical histories notable for surgeries, hypercoagulation disorders, infections, and trauma. In trauma-linked dAVF, presentation generally occurs within 48 h post-incident. In the present case, the authors discuss the delayed onset of a Borden type II dAVF in a patient 12 hospital days post-trauma, as well as the course of treatment. This unique case provides a compelling demonstration for providers to be aware of the development of dAVF, even after the typical 48-hour post-trauma window. By being aware of the possibility of delayed dAVF presentation, delayed diagnosis or misdiagnosis can be avoided and emergent action can be taken.

Rescue Procedures

Disabled submarine (DISSUB) survivors are expected to achieve saturation with inert gas. However, rescue procedures may not accommodate staged decompression, raising the potential for severe decompression sickness (DCS). Alternatives to standard recompression therapy are needed. It has been demonstrated in humans that isobaric oxygen “prebreathing” (OPB) can accelerate decompression in a DISSUB scenario. In-70 kg swine saturated at 2.82 atm absolute (ATA), 1 h of OPB eliminated death and reduced severe DCS. We hypothesized that even shorter periods (<1 h) of OPB before no-stop decompression from saturation at 2.82 ATA could reduce the incidence of DCS in a large animal model. Catheterized Yorkshire swine (68.8 ± 1.7 kg) in individual Plexiglas boxes within a large animal hyperbaric chamber were compressed to 2.82 ATA for 22 h. Following saturation and while still at depth, breathing gas was switched to >95% O2 for 45 min (OPB45), 15 min (OPB15), or 5 min (OPB05) of OPB, or no OPB (control). The chamber was then decompressed without stops (0.91 ATA/min). Observers then entered the chamber and recorded signs of DCS for 2 h. All OPB periods significantly reduced the risk of developing type II DCS. OPB45 eliminated severe DCS. Controls had a 2.5 times greater risk of developing type II DCS than OPB05 ( P = 0.016). OPB45 and OPB15 significantly reduced type I DCS compared with controls. These results support the potential of OPB as an alternative to staged decompression and that OPB could be expected to improve outcome in a DISSUB rescue scenario.

AbstractDuplication of the urethra is a rare congenital anomaly, with approximately 300 cases reported in the literature. We report a unique case of this condition in a male infant. This case differs from the classical Effman type II-A2 duplication because of the presence of two hypospadic urethral meati, as opposed to a ventral or dorsal accessory meatus with a normally positioned distal urethra. The patient underwent a single-stage repair consisting of a proximal urethra-urethral anastomosis and distal urethral tubularization at 21 months of age with excellent results in terms of both function and cosmesis.

Hypertrophic cranial polyneuropathy (HCP) is sporadically encountered in clinical practice. Aetiologies of HCP have been classified as autoimmune, infectious and demyelinating. However, an accurate diagnosis remains elusive in some cases despite rigorous investigations. These cases represent idiopathic HCP. Given the high clinical variance in presenting symptoms, HCP often leaves medical practitioners in a diagnostic quandary. Here, we seek to expand current knowledge by reporting the first documented case of idiopathic HCP presenting atypically with unilateral orbital pain and exclusively involving the bilateral trigeminal nerves.
