Case report: "an unexpected origin of coma in a young adult".

We report a peculiar case of acute non-traumatic coma due to neuromuscular hypoventilation syndrome caused by a non-traumatic spinal cord injury (NTSCI). A 21-year-old patient presented to the emergency room complaining of sudden onset weakness in his lower limbs and shortness of breath. While in the ER, he briefly became comatose and labs revealed an acute respiratory acidosis. Detailed neurologic examination ultimately revealed upper motor neuron signs and quadriplegia. He was ultimately diagnosed with a non-traumatic spinal cord injury, in particular, a cervical transverse myelitis which had caused acute diaphragmatic weakness. Although a very rare cause of coma, emergency medicine physicians need to be aware of transverse myelitis, a disorder that may result in rapidly progressive neurologic decline and is treated with immunomodulation.

Snakebites in Suriname: Evaluation of the Protocolled Administration of Anti-Snake Venom in a Tertiary Care Setting.

Venomous snakebites regularly occur in Suriname, a middle-income country located on the north coast of South America. Officially reported data on incidence and mortality are lacking. The aim of this retrospective study was to assess whether the use of our national snakebite protocol with selective administration of anti-snake venom (ASV) in patients with signs of snakebite envenoming improved clinical outcome as measured by mortality and length of stay (LOS) in the hospital. Medical records of all patients admitted at the Academic Hospital Paramaribo from 2013 to 2015, before and after the introduction of the protocol, with signs of snakebite envenoming, were reviewed for demographics, snakebite characteristics, mortality, length of hospital stay, administration of ASV, and occurrence of complications. Secondary outcome measures were the development of late complications due to a snakebite. Sixty-eight and 76 patients in 2013 and 2015, respectively, with venomous or potentially venomous snakebites were identified. One patient (1.5%) in 2013 and 29 patients (38.2%) in 2015 received ASV. In 2013 one patient died: deterioration of renal function occurred before protocolled ASV administration. No deaths were reported in 2015. There was no difference in the overall length of hospital stay between 2013 and 2015 or in the total number of late complications. In 2015, the mean LOS (±SD) for patients who did not receive ASV (n = 47) was significantly lower than that for patients who received ASV (n = 29), 2.15 ± 2.27 versus 5.31 ± 5.53 days, respectively (P = 0.001). The mean LOS (±SD) for patients who did not receive ASV in 2013 (n = 67) and 2015 (n = 47) was 4.06 ± 5.44 and 2.15 ± 2.27 days, respectively, which also differed significantly (P = 0.025). The protocolled evaluation of snakebite victims resulted in more patients being admitted to the intensive care unit and receiving ASV and a shorter length of hospital stay for the patients who did not receive ASV, and no difference in the occurrence of complications was observed in Suriname's largest hospital responsible for the acute care of snakebite victims.

A rare infection in the tropics that is not uncommon in cases of chronic granulomatous disease.

Chromobacterium violaceum is a rare cause of infection in immunocompromised patients in the tropics with a spectrum of disease manifestations, including severe disease. Early identification of this micro-organism is essential for appropriate management. We present a case of C. violaceum septicaemia in a patient with chronic granulomatous disease.

Paroxysmal autonomic instability with dystonia in a patient with tuberculous meningitis: a case report.

INTRODUCTION: This case report describes an extremely rare combination of paroxysmal autonomic instability with dystonia and tuberculous meningitis. Paroxysmal autonomic instability with dystonia is normally associated with severe traumatic brain injury. CASE PRESENTATION: A 69-year-old man of Indonesian descent was initially suspected of having a community-acquired pneumonia, which was seen on chest X-ray and computed tomography of the chest. However, a bronchoscopy showed no abnormalities. He was treated with amoxicillin-clavulanic acid in combination with ciprofloxacin. However, nine days after admission he was disorientated and complained of headache. Neurological examination revealed no further abnormalities. A lumbar puncture revealed no evidence of meningitis. He was then transferred to our hospital. At that time, initial cultures of bronchial fluid for Mycobacterium tuberculosis turned positive, as well as polymerase chain reaction for Mycobacterium tuberculosis. Later, during his stay in our intensive care unit, he developed periods with hypertension, sinus tachycardia, excessive transpiration, decreased oxygen saturation with tachypnea, pink foamy sputum, and high fever. This constellation of symptoms was accompanied by dystonia in the first days. These episodes lasted approximately 30 minutes and improved after administration of morphine, benzodiazepines or clonidine. Magnetic resonance imaging showed an abnormal signal in the region of the hippocampus, thalamus and the anterior parts of the lentiform nucleus and caudate nucleus. CONCLUSIONS: In patients with (tuberculous) meningitis and episodes of extreme hypertension and fever, paroxysmal autonomic instability with dystonia should be considered.

Mast cells are involved in inflammatory reactions during Complex Regional Pain Syndrome type 1.

BACKGROUND: The Complex Regional Pain Syndrome type 1 (CRPS1) is a complication of surgery or trauma but spontaneous development is also described. Although the pathogenesis remains debatable, afferent, efferent and central nervous system mechanisms are proposed. Recently we showed involvement of the proinflammatory cytokines IL-6 and TNFalpha which is direct evidence for an inflammatory process. Many types of cells, such as activated T lymphocytes, monocytes, macrophages and skin resident cells like mast cells, could contribute to the production of cytokines. Involvement of mast cells is relatively easy to detect by measurement of tryptase. AIM: To establish whether mast cells are involved in the inflammatory reactions during CRPS1. METHODS: Twenty patients fulfilling the Bruehl criteria with CRPS1 in one extremity were studied. Impairment was assessed by registration of pain and measurement of differences in temperature, volume and mobility between the involved and uninvolved extremity. Blisters were made with a suction method in order to determine cytokines and mast cell derived tryptase in the involved and uninvolved extremity. RESULTS: In the blister fluid a significant difference (median +/- interquartile range, Wilcoxon signed-ranks test P < 0.05) was found between the involved and uninvolved extremity in IL-6 [53.5 (17.3-225) versus 6.2 (2-20.3) pg/ml], TNFalpha [31 (15.5-131.5) versus 8 (4-39) pg/ml], and tryptase [37 (20.5-62.3) versus 12.5 (6.7-23.5) ng/ml]. There was a significant correlation (0.455) between the intensity of pain and tryptase levels in the involved extremity (Spearman's test, P < 0.05). CONCLUSION: Mast cells are involved in inflammatory reactions during the CRPS1. Mast cells could play a role in the production of cytokines such as TNFalpha.
