Rare association of herpes simplex virus IgM-specific antibodies and Guillain-Barré syndrome successfully treated with plasma exchange and immunosuppression
Herpes simplex virus (HSV) has been associated with various neurological disorders. In contrast, HSV infection is very rarely found in acute polyneuroradiculitis. In this report, a patient is described with a severe course of Guillain-Barr¿ syndrome (GBS). HSV IgM-specific antibodies and a rise of complement-fixation antibodies were detected. During the acute phase of neurologic syndrome, a nerve biopsy showed myelin damage and IgM deposits on the inner layer of the perineurium. Plasma exchange, in combination with immunosuppression, was successfully applied as a treatment in the relapsing course of GBS. Finally, after recovery, HSV-specific IgM antibodies disappeared.
Hypokalemic rhabdomyolysis associated with Bartter's syndrome.
Severe potassium deficiency is an uncommon cause of rhabdomyolysis. We recently treated a 45-year-old patient with myalgia, serious generalized weakness, increased serum creatine kinase and myoglobin level as well as excessive hypokalemia. Histological examination of deltoid muscle biopsy showed rhabdomyolysis. After complete recovery of muscle damage by potassium substitution Bartter's syndrome proved to be the cause of initial and persistent hypokalemia.
Überprüfung der Läsionsgefahr des N. ischiadicus des Kaninchens durch die Applikation niedrig- und mittelenergetischer extrakorporaler Stoßwellen
Aim The aim of the study was to evaluate the likeliness for peripheral nerve lesions following extracorporeal shock wave application. Material and method 82 rabbit sciatic nerves were randomized to undergo low-energetic (0.08 mJ/mm2), middle-energetic (0.28 mJ/mm2) or no (controls) shock wave therapy. After 1 to 28 days an independent neuropathologist checked the specimen for signs of neural lesions. Results Only after 14 and 28 days vacuolic swelling of the axons was noted, somewhat pronounced in the middle-energetic group. In no case was there any disruption of the nerve's continuity. We did not observe any neurapraxia. Conclusion Shock wave application does not threaten peripheral nerve …
Traumatic lesion of the extracranial vertebral artery--a note-worthy potentially lethal injury.
The autopsy findings from routine neuropathological investigations of the cervical spine after any history of trauma emphasized the vulnerability of the extracranial vertebral arteries. In 21 cases with trauma to the head and neck, normal autopsy procedures did not succeed in revealing an obvious cause of death. Traumatic lesions of the spinal cord such as contusion or neurorrhexis were seen in 10 cases. In 15 cases we observed different degrees and stages of traumatic lesions of the extracranial vertebral arteries. Sudden death due to acute brain stem ischemia might be considered as an explanation in some of these cases. Six case reports with traumatic vertebral artery (VA) lesions after s…
