The scientific history of hydrocephalus and its treatment 总被引:3,自引:0,他引:3
Summary Hydrocephalus cases were regularly described by Hippocrates, Galen, and early and medieval Arabian physicians, who believed
that this disease was caused by an extracerebral accumulation of water. Operative procedures used in ancient times are neither proven by skull findings today nor clearly
reported in the literature. Evacuation of superficial intracranial fluid in hydrocephalic children was first described in
detail in the tenth century by Abulkassim Al Zahrawi. In 1744, LeCat published findings on a ventricular puncture.
Effective therapy required aseptic surgery as well as pathophysiological knowledge – both unavailable before the late nineteenth
century. In 1881, a few years after the landmark study of Key and Retzius, Wernicke inaugurated sterile ventricular puncture
and external CSF drainage. These were followed in 1891 by serial lumbar punctures (Quincke) and, in 1893, by the first permanent
ventriculo-subarachnoid-subgaleal shunt (Mikulicz), which was simultaneously a ventriculostomy and a drainage into an extrathecal
low pressure compartment. Between 1898 and 1925, lumboperitoneal, and ventriculoperitoneal, -venous, -pleural, and -ureteral
shunts were invented, but these had a high failure rate due to insufficient implant materials in most cases. Ventriculostomy
without implants (Anton 1908), with implants, and plexus coagulation initially had a very high operative mortality and were
seldom successful in the long term, but gradually improved over the next decades.
In 1949, Nulsen and Spitz implanted a shunt successfully into the caval vein with a ball valve. Between 1955 and 1960, four
independent groups invented distal slit, proximal slit, and diaphragm valves almost simultaneously. Around 1960, the combined
invention of artificial valves and silicone led to a worldwide therapeutic breakthrough. After the first generation of simple
differential pressure valves, which are unable to drain physiologically in all body positions, a second generation of adjustable,
autoregulating, antisiphon, and gravitational valves was developed, but their use is limited due to economical restrictions
and still unsolved technical problems. At the moment, at least 127 different designs are available, with historical models
and prototypes bringing the number to 190 valves, but most of these are only clones.
In the 1990s, there has been a renaissance of endoscopic ventriculostomy, which is widely accepted as the method of first
choice in adult patients with aquired or late-onset, occlusive hydrocephalus; in other cases the preference remains controversial.
Both new methods, the second generation of valves as well as ventriculostomy, show massive deficits in evaluation. There is
only one randomized study and no long-term evaluation.

Selection criteria for treatment of rectal cancer with combined external and endocavitary radiation 总被引:2,自引:2,他引:0
Dr. Elisa H. Birnbaum M.D. Olagunju A. Ogunbiyi M.D. Giuseppe Gagliardi M.D. Robert D. Fry M.D. Robert J. Myerson M.D. Ira J. Kodner M.D. James W. Fleshman M.D. 《Diseases of the colon and rectum》1999,42(6):727-733
PURPOSE: The aim of this study was to identify factors predictive of recurrence of rectal tumors treated with combined external and endocavitary radiation. METHODS: Seventy-two patients with rectal cancer were evaluated clinically and with transrectal ultrasound before combined external and endocavitary radiation. Ideal lesions were moderately differentiated, mobile, not ulcerated, <3 cm in diameter, and <12 cm from the anal verge. External radiation (4,500 cGy) was given during five weeks followed by endocavitary radiation (3,000 cGy × 2). Median follow-up was 31 (range, 7–93) months. RESULTS: Pretreatment transrectal ultrasound stages were uT1 (6 patients), uT2(27 patients), and uT3 (39 patients). Clinical evaluation identified 26 ideal and 46 nonideal tumors. Overall recurrence was 36 percent; mean time to recurrence was 12 months. Ideal lesions recurred less than nonideal (15vs. 48 percent;P=0.01). Mobile lesions recurred less than tethered lesions (26vs. 52 percent;P=0.048). Transrectal ultrasound stage was predictive of recurrence (0 percent uT1, 22 percent uT2, and 51 percent uT3;P=0.015). Surgery was possible in 14 of 17 patients with pelvic recurrence only; 11 patients (65 percent) had curative surgery. Distant metastases occurred in nine patients; all had pelvic recurrences, and six died of disease. CONCLUSION: Patients with uT3 or nonideal rectal cancers should not be offered combined external and endocavitary radiation for cure. Transrectal ultrasound stage is the only independent predictor of recurrence.Presented at the meeting of The American Society of Colon and Rectal Surgeons, Philadelphia, Pennsylvania, June 22 to 26, 1997. 相似文献

ObjectiveTo determine the effectiveness of hip arthroscopy combined with endoscopic iliotibial band (ITB) release in patients with both femoroacetabular impingement (FAI) syndrome and external snapping hip (ESH).MethodsRetrospectively review the preoperative and minimum of 2‐year follow‐up data of patients with both FAI syndrome and ESH who underwent endoscopic ITB release during hip arthroscopy (FAI + ESH group) from January 2014 to December 2018. The same number of age‐ and gender‐matched FAI syndrome patients without ESH undergoing hip arthroscopy were enrolled in the control group (FAI group). Patient‐reported outcomes (PROs) including international Hip Outcome Tool (iHOT‐33), modified Harris Hip Score (mHHS), visual analog scale for pain (VAS‐pain), and abductive force of affected hip at 3 month and 2 years postoperatively were comparatively analyzed. The VAS‐satisfaction score of two groups at 2 years postoperatively were also analyzed.ResultsThe prevalence of ESH in FAI syndrome patients undergoing hip arthroscopy in our institution was 5.5% (39 of 715 hips), including nine males (10 hips) and 29 females (29 hips). The mean age at the time of surgery was 32.1 ± 6.9 years (range, 22–48 years). According to inclusion and exclusion criteria, 23 patients were enrolled in FAI + ITB group. Twenty‐three age‐ and sex‐matched FAI syndrome patients were enrolled in FAI group. At 24 months postoperatively, no patient still suffered ESH symptoms and painful palpation at lateral region in FAI + ITB group. The iHOT‐33, mHHS, and VAS‐pain score of patients in FAI + ESH group were significantly severer than patients in FAI group preoperatively (41.6 ± 7.5 vs 48.8 ± 7.2, 54.8 ± 7.2 vs 59.2 ± 6.9, 5.5 ± 0.9 vs 4.7 ± 1.0; P < 0.05), while there was no significant difference in these scores between the patients in FAI + ESH group and FAI group at 3‐month and 24‐month follow‐up (73.6 ± 8.5 vs 76.1 ± 6.9, 85.3 ± 7.8 vs 84.2 ± 6.6, 0.8 ± 0.9 vs 0.6 ± 0.9; P > 0.05). At 3 months after surgery, the abductive force of operated hip was significantly smaller than that in FAI group (82.4 ± 12.4 N vs 91.9 ± 16.1 N, P < 0.05), whereas there was no significant difference at 24 months after surgery (101.6 ± 14.9 N vs 106.5 ± 13.7 N, P > 0.05). The VAS‐satisfaction scores of patients in the two groups were at a similarly high level (90.5 ± 6.8 vs 88.8 ± 7.3, P > 0.05). There was no complication and no arthroscopic revision in either group until 2‐year follow‐up.ConclusionAlthough abductive force recovery of the hip was delayed, hip arthroscopy combined with endoscopic ITB release addressed hip snapping in patients with both FAI syndrome and ESH, and could get similar functional improvement, pain relief, recovery speed, as well as patient satisfaction compared with the pure hip arthroscopy in FAI syndrome patients without ESH. 相似文献

BACKGROUND: High-frequency oscillatory ventilation (HFOV) has become the preferred method of ventilation for the fragile lungs of neonates and infants because its beneficial effects on lungs are well known; however, its benefits on upper airways are not yet known. We investigated the effects of HFOV and conventional mechanical ventilation (CMV) on the airways of kittens with normal lungs. METHODS: Ten healthy cross-bred kittens, 2-3-months-old, with a mean bodyweight of 0.98 kg, were randomly divided into two groups: HFOV and CMV. Kittens were intubated and ventilated for 24 h. A semiquantitative scoring system was used to grade histopathological tissue changes in the cricoid, mid-trachea, carina and left bonchus. The injury scores of the two groups were ranked and compared using a two-tailed Mann-Whitney rank test. RESULTS: Histopathologic changes were similar and mild in both groups under light microscopic examination. There was no significant difference in airway injury between the two groups. CONCLUSIONS: We conclude that, in this animal model, HFOV results in minimal airway damage when properly managed and causes no greater tracheobronchial injury than CMV. 相似文献
