Suffocation of nerve fibers by living nanovesicles: a model simulation.

A model using nanospheres to allow the simulation of the nonspecific interaction of nanobacteria (NB), one with another or with body tissues, is established. Depending primarily on their concentrations and stress levels, these apatite nanovesicles may nucleate thrombogenic conglomerates in blood, or self-assemble to dense nanoclay layers on surfaces in the body. Partial or total encapsulation of nerve fiber bundles by such mineral layers may interrupt the metabolic exchanges between the surrounded tissue and its immediate environment and may restrict signaling processes. The presented model could provide detailed insight into plaque formation triggered by NB, and the parameters encouraging it.

Suffocation of nerve fibers by living nanovesicles: a model simulation--part II.

Nanobacteria may cause peripheral neuropathy by adhesion to the perineurium. This hypothesis receives support from five independent observations: (1) identification of perineurial apatite in diabetic patients with peripheral neuropathy, (2) massive presence of nanobacteria in a diabetic patient, (3) beneficial effect of lasers on peripheral neuropathy, (4) model simulation indicating that perineurial deposition and attachment of nanobacteria is encouraged by both their size and chemical nature, and (5) transient inhibition of neural function by apatite. Initial deposition of (stressed) nanobacteria is promoted by a slime thought to consist of proteins, calcium, and phosphate, and is most likely followed by an immobilization phase, mediated by a bioadhesive capacity of the apatite. Proteomics may hold the key to control both attachment processes.

Resuscitation by extracorporeal lung assist of a patient suffocating after inhalation of sawdust particles.

A 17-yr-old male accidentally inhaled a massive amount of sawdust particles. Severe respiratory distress developed, resulting in subcutaneous emphysema and left pneumothorax. Therefore, sufficient positive-pressure ventilation was inapplicable. Under veno-venous extracorporeal lung assist (ECLA) with an artificial lung, the sawdust particles were removed by broncho-fibroscopy and lung lavage. After 36 h, the patient was weaned from ECLA without further complications.

Sudden suffocation by surgical sponge retained after a 23-year-old thoracic surgery.

A 70-year-old male patient with a 23-year-old history of right lower lung lobectomy for primary pulmonary adenocarcinoma (T1 N0 M0) presented with recurrent bronchopneumonia and purulent sputum. Pleural callus, lung abscess, bronchopleural fistula, and stitch granulomas were confirmed by chest x-ray, computed tomography scan, and bronchoscopy in the background of his complaints. An attempt to remove the bronchial purulent discharge and tissue sampling was made by using a flexible bronchoscope. The area of the lower trachea suddenly became clogged during bronchoscopic removal of the suspected piece of tissue (which later turned out to be organizing surgical gauze). The resuscitation following ventricular fibrillation failed to save the patient's life. The forensic postmortem examination confirmed the position of the foreign body extending from the abscess cavity, crossing the midline at carina and obstructing the lower trachea. This foreign body was a remnant of the surgical gauze left behind during a thoracic surgery 23 years ago.
