Congenital central hypoventilation syndrome (Ondine's curse syndrome) in two siblings: Delayed diagnosis and successful noninvasive treatment

Congenital central hypoventilation syndrome (CCHS, Ondine's curse syndrome) is a rare respiratory disorder; less than 100 cases have been reported. Familiality of the disease has been discussed, but only few familial cases have been reported so far. In this report we describe the occurrence of CCHS in two male siblings. Diagnosis was established only at the age of 4 years in the first case, although the patient had disease related symptoms since early infancy. The second patient was one of dizygotic twins, he was diagnosed with CCHS at the age of 8 months. Up to that age only moderate desaturations had been observed. The other twin was unaffected by the disease. Both patients were successfully treated by nocturnal positive-pressure ventilation via a specially adapted face mask. They show satisfactory physical and neurologic development.     

Pseudoparadoxical dissociation of cerebral oxygen saturation and cerebral blood flow velocity after acupuncture in a woman with cerebrovascular dementia: a case report

Acupuncture can increase both cerebral oxygen saturation and cerebral blood flow velocity. We describe a 77-year-old woman with cerebrovascular dementia in whom acupuncture reproducibly induced an increase of blood flow velocity but a decrease of regional oxygen saturation. At four of 11 acupuncture sessions, blood flow velocity was measured in the middle cerebral artery with transcranial Doppler sonography and cerebral regional oxygen saturation (rSO(2)) with transcranial near infrared spectroscopy. Cerebral blood flow velocity increased by an average of 20% (range: 7-27%) at all four study points whereas rSO(2) consistently decreased by an average of 7% (range: 4-13%). Clinical status and cognitive function improved. These findings in a patient with vascular dementia may suggest increased oxygen extraction by activated neuronal structures.     

Laser doppler flowmetry in combined needle acupuncture and moxibustion: a pilot study in healthy adults

Laser Doppler flowmetry (LDF) (DRT 4/Moor Instruments Ltd, Devon, UK) was used in this pilot study for monitoring the effects of an invariable acupuncture pattern on microcirculation of the skin before, during, and after combined needle acupuncture and moxibustion in 12 healthy volunteers (mean age 35.2±4.4 years, range 26–41 years, four female and eight male). According to the standards of traditional Chinese medicine (TCM), this acupuncture pattern is assumed to be unspecific and non-therapeutic. Flux decreased during the treatment period (p<0.05) compared to the control phase before combined needle acupuncture and moxibustion. After the removal of the needles, flux did not return to the initial control value. No significant differences between mean arterial blood pressure, heart rate, skin temperature or gender were detected. A prediction of individual incidences and kinds of acupuncture effects in our healthy volunteers was not possible. Modern monitoring techniques like LDF could be a method to separate responders from non-responders to acupuncture in peripheral microcirculatory disorders. Further studies on patients with peripheral microcirculatory disorders are necessary in order to demonstrate the value of LDF in detecting responders/non-responders in combination with therapeutic acupuncture patterns according to TCM.

Effects of QiGong on brain function

QiGong is an ancient and widely practiced Chinese meditation exercise. We studied the effects of QiGong on brain function with modern neuromonitoring tools in two subjects. In a male QiGong master (extremely trained practitioner), the technique induced reproducible changes in transcranial Doppler sonography, EEG, stimulus-induced 40 Hz oscillations, and near-infrared spectroscopy findings. Similar effects were seen after the application of multimodal stimuli and when the master concentrated on intense imagined stimuli (e.g. 22.2% increase in mean blood flow velocity (vm) in the posterior cerebral artery, and a simultaneous 23.1% decrease of vm in the middle cerebral artery). Similar effects were seen in the female subject. Neuromonitoring during QiGong appears able to objectify accompanied cerebral modulations surrounding this old Chinese meditation exercise.

Ultrasound-monitored effects of acupuncture on brain and eye.

A new transcranial Doppler sonography arrangement was used to monitor blood flow profiles in the supratrochlear and middle cerebral arteries simultaneously and continuously. The technique selectively demonstrated the specific effect of acupuncture on the cranial arteries, in a 25-year-old female with pigmentary retinopathy. Stimulation of points Zanzhu and Yuyao led to a marked increase of blood flow velocity in the supratrochlear artery and to a decrease of flow velocity, in the middle cerebral artery. These acupuncture-induced effects were reproducible even though both arteries originate from the same major vessel.     

Studies of brain stem function in infants with apnea syndrome using acoustically evoked brain stem potentials and heart rate variability

Twenty-four infants aged between 6 days and 7 months and 2 infants (16 m and 3 y) were subjects of combined brain-stem auditory evoked potential and heart rate variability measurements. Ten infants had a sleep apnea syndrome and one a Near miss sudden infant death syndrome; thirteen infants formed the control group. Seventeen of the twenty-six infants had normal, age-depended brain stem potentials. All infants of the apnea syndrome-group, which had no therapy, had increased I to V interpeak latencies outside of the one-sigma level, the six infants treated with aminophylline were within the normal range. Heart rate variability measurements revealed the following mean +/- standard deviation of the control group: 4.5% +/- 1.5%; of the apnea syndrome-group without therapy: 5.4% +/- 2.0%.
