BACKGROUND Accidental dural puncture during epidural blockade is a rare complication. Since postdural puncture headache (PDPH) is the most frequent complication, a wisely management method will also reduce the incidence of PDPH. METHODS Five patients who had inadvertent dural puncture during the epidural procedure before hip or knee arthroplasty were included in this study. After dural punctu...

The efficiency of three oocyte collection methods from goat ovaries was assessed. Oocytes were collected by aspiration (n=165), slicing (n=213) and puncture (n=172). The mean yield of oocytes per ovary was found to be 3.93 ± 0.11, 4.44 ± 0.06 and 3.59 ± 0.07 by aspiration, slicing and puncture respectively. Slicing yielded significantly higher number of oocytes per ovary. Percentage yield of cu...

OBJECTIVE To see whether the incidence of cerebral herniation is increased immediately after lumbar puncture in children with bacterial meningitis and whether any children with herniation have normal results on cranial computed tomography. DESIGN Retrospective review of case notes; computed tomograms were read again. SETTING Large paediatric teaching hospital. SUBJECTS 445 children over 3...

BACKGROUND Puncture biopsy and fine needle aspiration guided by endoscopic ultrasound has been used as an effective technique and is quickly becoming the procedure of choice for diagnosis and staging in patients suspected of having pancreatic cancer. This procedure has replaced retrograde cholangiopancreatography and brush cytology due to its higher sensitivity for diagnosis, and lower risk of ...

The effects of a conductive or mixed (conductive and sensorineural) hearing loss on anatomical and physiological properties of the chicken auditory system were examined. Animals used in the anatomical studies underwent either a columella (ossicle) removal, which produced a moderate conductive hearing loss, or an oval window puncture, which produced a severe mixed hearing loss, at 4 days posthat...

DIPLOPIA or extraocular muscle paralysis (EOMP) after dural puncture has been reported occasionally, primarily in the neurology and ophthalmology literature. Because there seems to be a window period before diplopia manifests after dural puncture, the patient and physician may not always believe that the symptom is secondary to dural puncture, particularly when it occurs after resolution of a p...

Arthrocentesis is a simple conservative surgical procedure with minimal invasion performed to flush the inflammed TMJ. This treatment modality has been well in practice since over two decades now. Recently, the concept of single puncture arthrocentesis has been introduced and is gaining wide popularity. We believe that the concept of single puncture has revolutionized the traditional technique ...

Puncture force and energy were measured at different loading velocities and probe diameters for two cultivars of sea buckthorn berries of various sizes at several ambient temperatures. In addition to the puncture properties, the firmness-temperature coefficient, the compression coefficient (Kc), shear coefficient (Ks), and the apparent modulus of elasticity were determined. The tests showed tha...

BACKGROUND Lumbar puncture is often used for the diagnosis and treatment of subarchnoid hemorrhage, infection of Cerebro-spinal Fluid (CSF), hydrocephalus in neurosurgery department patients. It is general that paradoxical herniation followed by lumbar puncture is quite rare in decompressive craniectomy cases; the related reports are very few. Moreover, most of the paradoxical herniation cases ...
