Diagnostic investigations. Part 1. Lumbar puncture.

This article, the first in a three-part series on clinical investigations, discusses the technique and uses of lumbar puncture. This diagnostic procedure involves making a puncture into the subarachnoid space of the spinal cord, to remove an excess of fluid; to obtain fluid for examination and analysis, or to inject medication. The article includes an explanation of the relevant anatomy and the composition and role of cerebrospinal fluid, a detailed description of the procedure and the interpretation of results.

[Epidural spinal hematoma after lumbar puncture].

Three days after a lumbar puncture in a 7 month old child with pyogenic meningitis and without any blood clotting defect, appeared symptoms of spinal cord compression. Myelography led to surgery, 5 days after the puncture. At operation, an epidural hematoma, from L1 to L5 was removed. The exceptional character of this accident and its cause are discussed.

Embolization of the AVM of jaws by direct percutaneous puncture combined with endovascular route.

OBJECTIVE: To report our experience to embolize the AVM of jaws by direct puncture in conjunction with endovascular treatment. METHODS: 5 cases of AVM of mandible and 2 cases of AVM of maxilla comprised this study group. The patients were embolized with coils with wool strands and PVA. The coils were placed directly into the center of the intraosseous lesion. The procedure was under the guidance of DSA machine (PHILIPS V3000). RESULTS: The acute arterial bleeding of 4 patients was controllable. The chronic oozing bleeding in the other 3 cases disappeared in the 3 - 24 months follow-up and new bone formation was found in the follow-up radiography. CONCLUSIONS: The embolization of the AVM of jaws by direct puncture in conjunction with endovascular therapy is effective and safe, however the longer follow-up is expected.

[Clinical analysis of 22 cases of Bartholin gland cyst or abscess treated with trocar puncture].

This study was designed to observe the effects of trocar puncture in the treatment of Bartholin gland cyst or abscess. The cure rate of these 22 cases was 100%, and no relapse of the disease occurred during the follow-up lasting for 5 to 12 months. Trocar puncture proves to be effective in the treatment of bartholin gland cyst or abscess, especially when the size is less than 3.0 cm.

[Lumbar puncture and early neuroimaging in complex febrile seizures. Report of a case of shaken infant syndrome].

INTRODUCTION: Febrile convulsions are one of the most frequent pathologies seen in paediatric emergencies. The diagnosis of febrile seizures is clinico evolutionary and is easily established once the acute process is overcome and a normal state is restored in the child. The differential diagnosis is established with the processes that associate fever and convulsions in children between the ages of 1 month and 6 years, many of which require specific treatment. Certain complementary examinations, essentially a blood test, lumbar puncture and neuroimaging, are needed to identify them. Shaken infant syndrome is a form of physical abuse which includes the presence of intracranial traumatic injury, retinal haemorrhage and, in general, the absence of other physical signs of traumatic injury in the child. CASE REPORT: An 8 month old infant who presented a convulsive seizure on the left side of the body which coincided with an axillary temperature of 38 C that remitted with intravenous diazepam 40 minutes after onset. An early cranial computerised tomography (CT) scan led to a diagnosis of shaken infant syndrome. DISCUSSION: This case constitutes an argument in favour of performing an early cranial CT scan in complex febrile convulsions and in prolonged or partial non provoked seizures. We highlight the risks involved in performing a lumbar puncture in the absence of suspected non complicated acute bacterial meningitis. The diagnostic usefulness of an early CT scan in diagnosing such an important problem as shaken infant syndrome must also be noted, due to the risk of repetition and its high morbidity and mortality rates.

[Complications of the sternal puncture (author's transl)].

The case of a 57 year old female patient suffering from plasmocytoma with a sternal fracture after local puncture characterized by a late healing tendency is reported. According to the literature the complications of this diagnostic method, known up to now, are described with special emphasis to the pathomechanism and the clinical course of the mostly fatal sternal perforation with cardiac tamponade. Puncture of the iliac crest instead of the sternal region is recommended in cases with serious osteoporotic or osteolytic defects of the sternal bone.

Direct percutaneous puncture of a cervical internal carotid artery aneurysm for coil placement after previous incomplete stent-assisted endovascular treatment.

Direct percutaneous puncture for coil placement has been described for visceral aneurysms, but the procedure has not been previously reported for aneurysms of the head and neck. We report a case in which stent-assisted endovascular treatment was successfully combined with direct puncture for additional coil placement to treat a symptomatic giant aneurysm of the cervical internal carotid artery.

[The puncture treatment in frontal sinusitis (author's transl)].

Patients suffering from acute or chronic frontal sinusitis should be treated by a drill-puncture of the anterior wall. A chronic cannula or a plastic tube is inserted and the sinusitis by this way influenced directly. In more than 60% of the cases the sinusitis can be cured and an operation is prevented. The procedure should be combined with a control of the nasal septum and the medial turbinate. Recidives of chronic frontal sinusitis after previous puncture should not a second time be treated using this method.

Direct left ventricular puncture.

Left ventricular puncture with ventriculography was carried out in 150 cases over the past four years as an adjunct to cardiac catheterization. It proved to be a safe method of obtaining data on abnormalities of the heart. In addition, it permitted excellent visualization of the thoracic aorta and brachiocephalic vessels. Inserting the needle at the subxiphoid and directing it through the apex of the right ventricle, into the septum and then the left ventricle lessened the hazard of injury to the left coronary artery or of entering the pleural cavity that is associated with direct apical puncture. Complications and failures were few.

Differentiation of benign and malignant lymph nodes with contrast-enhanced echolymphography using endoscopic ultrasound-guided puncture.

BACKGROUND/AIMS: Although endoscopic ultrasonography is considered the most useful diagnostic modality for the regional staging, the capability of diagnosing lymph node metastasis based on endoscopic ultrasonography images alone is not sufficient. To improve the capability of differential diagnosis of lymph node enlargement, contrast-enhanced echolymphography was performed using endoscopic ultrasonography-guided puncture. METHODOLOGY: Contrast-enhanced echolymphography was performed in 8 metastatic lymph nodes surgically resected from patients with gastrointestinal cancers (in vitro study) and also in 55 patients in whom abdominal lymph node swelling was indicated by endoscopic ultrasonography (in vivo study). Lymph nodes were punctured under real-time endoscopic ultrasonography guidance, and carbon dioxide microbubbles were injected to evaluate echo features before and after microbubbles injection. RESULTS: Contrast-enhanced echolymphography of freshly resected metastatic lymph nodes showed nonhomogeneous echo patterns. In regions demonstrating filling defects detected by contrast-enhanced echolymphography, neoplastic infiltration was pathologically observed. In almost all of the malignant lymph nodes studied in vivo, filling defects and heterogeneous enhancements were observed by contrast-enhanced echolymphography. However, contrast-enhanced echolymphography demonstrated uniform patterns in most of the benign group. The sensitivity, specificity, positive and negative predictive value, and accuracy of differential diagnosis by contrast-enhanced echolymphography were 95.8%, 90.3%, 88.5%, 96.6%, and 92.7%, respectively. CONCLUSIONS: Contrast-enhanced echolymphography is a useful method for help in the differentiation between reactive and malignant alterations of lymph nodes.

Late postpartum eclampsia coincident with postdural puncture headache: a case report.

Preeclampsia developed in this patient 4 days' postpartum. Visual changes, headache, and elevated blood pressures were present on arrival to the emergency department. Coincident with the preeclampsia was a postdural puncture headache complicating the diagnosis of late postpartum preeclampsia. Pregnancy-induced hypertension laboratory values were normal, and relief of the postdural headache and visual disturbances was obtained after placement of an epidural blood patch. Blood pressures continued to increase, however, and late postpartum eclampsia developed. We conclude that symptoms of a postdural puncture headache can mimic those of postpartum preeclampsia. Early recognition and treatment of postpartum preeclampsia may decrease patient mortality and morbidity by preventing late postpartum eclampsia.

Inferior ST-segment elevation following transseptal puncture for balloon mitral valvuloplasty is atropine-responsive.

ST-segment elevation in the inferior leads has been previously described following transseptal puncture for balloon mitral valvuloplasty. The mechanism, however, is obscure, and immediate left and right coronary angiography has not suggested that embolism or vascular spasm is the cause. We hypothesized that a neurally-mediated mechanism was responsible and have since treated 3 further patients with inferior ST-segment elevation following transseptal puncture for balloon valvuloplasty with intravenous atropine, with rapid resolution of ST-segment elevation in each case.

[Spinal and cerebral hematoma following diagnostic lumbar puncture with fatal course].

A 64-year-old man suspected of having neurosyphillis suffered subarachnoid spinal and cerebral ventricular hemorrhage after a diagnostic lumbar puncture. The main risk factor was trauma occurring during a difficult puncture. Both the diagnosis and the subsequent laminectomy were delayed. Blood migrated to both lateral ventricles, complicating the clinical course, which ended in death. The need for rapid diagnosis and treatment in such cases is revealed by both images and clinical course. A pathophysiologic explanation for these hemorrhagic events is provided.

[Puncture of central veins in homicide cases].

Puncture of a major cervical veins for insertion of a central venous catheter is a standard-method in resuscitation performed in emergency conditions. Even extensive lesion-marks due to punction are customarily seen by medico-legal practitioners, but in detail they may cause difficulties in differential diagnosis, when lesion marks caused by acts of violence directed straight against the neck are to be differentiated. Especially in the primary phase of inquiry about crimes of homicide these injuries due to punction are forensically important. Therefore frequency and methods of resuscitation efforts were evaluated in 453 crimes of homicide, committed in Göttingen and Berlin (subjects given by the Free University). Findings of the present study were that resuscitation measures were taken merely to a rate of 25%, and in proceeding a central venous catheter was not obligatorily inserted, moreover proceeding being regionally different. In Berlin a central venous catheter was inserted in 17 cases out of 77 resuscitated homicidal injuries, the rate being 24 cases out of 36 cases in Göttingen. In altogether 8 crimes of homicide committed by immediate attacks against the neck, a cervical vena was punctured, findings later being extensive effusions of blood marked around the tapped spot. The different ways to perform resuscitation may justify to point also at the forensic interest to discover the facts together with complete diagnosis in cases of crimes of homicide. That is why it may be vindicated to try to find out a proceeding, which does not lessen the effectiveness of resuscitative manoeuvres, yet by means of which forensical concerns are taken into consideration, too.(ABSTRACT TRUNCATED AT 250 WORDS)

Pars plana vitrectomy and lamina cribrosa puncture in absolute glaucoma.

Two patients with refractory end-stage glaucoma who had no light perception underwent pars plana vitrectomy and lamina cribrosa puncture to relieve pain and decrease intraocular pressure. The patients presented with blind, painful eyes and high intraocular pressure (> 40 mm Hg). After the procedure, the pain was relieved and the intraocular pressure was lowered in both cases. The patients remained asymptomatic. Pars plana vitrectomy and lamina cribrosa puncture might be related to the decrease of intraocular pressure, probably by facilitating drainage of aqueous humor through the optic nerve.
