[Pleural puncture biopsy--a diagnostic method in serofibrinous tuberculous pleurisy in children].

The biopsy of the parietal biopsy with the help of a needle has become an essential method of diagnosis in the adult patients with a pleural malady of an unknown etiology and may become a complementary paraclinical method in children. A sure diagnosis in the tubercular serofibrinous pleurisy with children is made by rendering evident the Koch bacillus on the direct test or in culture and by rendering evident the tubercular lesions on fragments of pleural biopsy puncture. The study is supported on the results obtained at the pleural biopsy puncture performed on a number of 6 children. In four cases out of six the histological test of the pleural fragment has rendered evident the presence of tubercular lymphoepithelioid nodulus with central necrosis, thus carrying the argument of certitude. The pleural biopsy puncture allows an early and sure diagnosis in over two-thirds of the pleurisies of a tubercular etiology.

Wound site as a predictor of complications following deep nail punctures to the foot.

The site of injury, condition of the nail, and type of foot covering were compared in 36 inpatients and 34 outpatients with nail puncture wounds to the foot. Of the 36 inpatients, 34 (94%) had pyarthrosis, osteomyelitis, or both. The plantar surface of the foot was divided into 3 zones. Of the 36 inpatients, 35 (97%) had deep puncture wounds in zone 1. In contrast, only 6 of 34 (18%) outpatients had injury to this area. Tennis shoes were shown to predispose to infection with Pseudomonas aeruginosa. Based on our findings, an early hospital admission should be considered for all patients with deep puncture wounds located in zone 1 and for patients who give a history of bone penetration in zone 2 or 3 at the time of injury. All patients who meet the above criteria and who are not admitted to hospital should be observed closely.

Overview of results with tracheoesophageal puncture after total laryngectomy.

Ten years have passed since the introduction of the tracheoesophageal puncture. The voice restoration field has dramatically changed upon the introduction of this new technique. This permits the patients to speak as early as ten days after surgery. An overview of the results of the past ten years are presented. In this communication the technique, historic highlights, and the published experience with tracheoesophageal puncture as a secondary, primary and in extended laryngopharyngectomy with flap reconstruction are discussed. Tracheoesophageal puncture with placement of voice prosthesis for voice restoration after total laryngectomy, has become an accepted technique. The popularity of this method originally proposed by Singer and Blom has been widespread. This new method of vocal rehabilitation after total laryngectomy, has permitted patients to speak as early as ten days after their surgery. This is a great advance in the rehabilitation of the cancer patient.

[Technical problems raised by renal puncture in the percutaneous extraction of coralliform calculi].

Initial puncture and dilation of nephrostomy track(s) remain difficult procedures in percutaneous extraction of staghorn calculi. Technical s adjuvants are necessary and are exposed in detail. The choice of the needle, of the wires and of the catheters for initial puncture and ureteral catheterization is explained. Techniques of "Y" tract and double puncture are exposed. Severe complications (3 cases) are reported. Extraction of up to 90% of the stone can be expected if these technical adjuvants are optimally used.

[CT-guided puncture biopsies of cystic processes in the cerebral and spinal areas].

Cystic space occupying processes are well imaged by CT because of their low density. For localization and identification of the surrounding brain structures additional coronary or secondary cuts can be used. Measurements of distances and angles from the intended point of puncture allow, with an appropriate technique, a free-hand puncture of the cyst. Needle position must be recorded with CT-images. No complications occurred in 22 patients. Punctures of cysts have only a symptomatic and transient effect. The immediate pressure reduction and the improvement of the clinical condition of the patient, however, can be valuable as an intermediate measure before surgery.

[Cutaneous implantation metastasis following fine-needle puncture of pancreatic cancer].

A case report form is given of a patient who developed a cutaneous implantation metastasis of a punctured pancreatic carcinoma. Needle biopsy of the tumor, located in the head of the pancreas, had been performed before, as well as drainage of the necrotic pancreas tail. Necrosis had been caused by pancreatitis due to stenosis of the pancreatic duct. This is a rare complication which may be due to local changes induced by puncture in the surroundings of the puncture channel.

[Ultrasonically-guided diagnostic punctures in pancreatic and adrenal diseases].

This study is based on the results of 38 punctures of adrenal and 62 punctures of pancreatic lesions measuring 1.5 to 12 cm (mean size: 4 cm in the pancreas; 6.5 cm in the adrenal glands). We used a free-hand technique with a mechanical sector probe. In the pancreas, the sensitivity of cytology is 67%, the specificity 100%. This low sensitivity is due to the difficulty in obtaining an adequate specimen when the tumor is predominantly fibrous. In the adrenal glands, the sensitivity is 90% and the specificity 100%. The results of our study are comparable to other series of guided punctures with US or CT reported in the literature. Microbiopsies with cutting needles can increase the sensitivity of the method in case of pancreatic tumors.

[Renal cyst puncture under ultrasound guidance: complications of ethanol injection].

Under ultrasound guidance, we treated 25 cases of renal cyst with 99% ethanol instillation to prevent the recurrence of this disease from January 1985 to June 1987. Patients' age was from 17 to 85 years old with the average age of 63 years. Twelve cases were men, and 13 cases were women. Among the 25 cases, eleven were asymptomatic and 14 showed clinical features of lumbago, microhematuria, hypertension or proteinuria. The aspirated site was the right side in 9, left side in 14 and bilateral kidneys in 2 cases. Subsequently, cyst puncture was carried out 27 times. We encountered 12 complications following puncture. These complications were derived from the puncture itself or caused by the ethanol instillation. Flank pain caused by the injection of ethanol, nausea, causalgia or a feeling of drunkenness appeared immediately after the inoculation procedure. However, no serious complications such as pneumothorax, perirenal hematoma or infection were recognized. Some complications arose in 7 cases of 9 examples (77.8%) following more than 50 ml of ethanol injection, but the complications were observed in only 5 cases of 18 examples (22.8%) following less than 50 ml of administration. Based on these findings, ethanol injection in renal cysts appears to be useful for the treatment of this disease. In case of huge cysts when more than 50 ml of ethanol, is instilled the case should be followed up carefully after the instillation procedure.

[History and significance of suboccipital puncture].

In 1919 Wegeforth, Ayer and Essick described the direct puncture of cisterna cerebello-medullaris. Without knowledge and independent of this Karl Eskuchen recommended in 1923 to tap the cistern after touching the squama occipitalis before. His proceeding found general resonance. It is less dangerous and practicable without much experience. Originally there were numerous diagnostical, therapeutical and scientific indications for the suboccipital puncture. Most of them are out of date. Still, it is the only practicable alternative when the lumbal puncture was with no purpose.

[Dynamics of follicle development in stimulated in vitro fertilization cycles--sonographic follow-up and findings following follicle puncture].

Results of ultrasonical folliculometry during treatment by 5 different stimulation protocols were evaluated in 122 cycles of IVF-patients. Additionally, the structure of follicular population was investigated by measurement of follicular volume which was the basis of a follicular hierarchy. - Number of developing, sonographically detectable and punctured follicles increased significantly from stimulation by Clomiphene to stimulation by Folistiman. Only in stimulation by Clomiphene number of sonographical visible follicles was in accordance with laparoscopically punctured follicles. Development of relationship of the follicular classes during treatment supports hypothesis that exogenous gonadotropins do not increase follicular recruitment in the follicular phase but prevent atresia of follicles recruited earlier. Long lasting action of FSH as in stimulation by gonadotropins stimulates a greater number of follicles more intensively as demonstrated by an increased follicular volume in follicles with high rank numbers in gonadotropin treated patients compared with treatment by Clomiphene and Clomiphene/Anthrogon. Very high FSH-levels probably cause a heterogenous population of follicles with an increased number of small follicles at time of follicular puncture.

[Polyethylene glycol in cytological puncture of the prostate].

Advantages of the use of polyethylene glycol (Fix-Frot solution) in prostate cytology were evaluated during a comparative study between a preliminary series of 75 examinations using conventional cytology techniques and a second series of 52 examinations using polyethylene glycol. The percentage of blank punctures decreased from 22.6 to 3.8%. Fixation was optimal and immediate; hemolysis of punctured red cells is ensured and use of Pananicolaou's stain allows very high quality analysis. The excellent sensitivity of prostate puncture cytology and its lack of complications place this procedure at the head of diagnostic explorations of prostate. Nevertheless, prostate cytology is difficult to perform and requires the availability of a very experienced cytologist.

[Radiation exposure of the patient and personnel during punctures controlled by roentgenotelevision and computed tomography].

Determined by means of thermoluminescent dosimetry radiation exposure to a patient from punctures controlled by two-projection x-ray and TV was, on an average, 0.0176 Gy +/- 18%, and when controlled by CT it was 0.048 Gy +/- 22% which was comparable with dose exposure of 2 x-ray films in the first case and of 5 x-ray films in the second case. Assessment of radiation exposure to a physician was based on the ratio of single and maximum permissible annual equivalent doses. This ratio of doses to the gonads limited the permissible number of punctures controlled by two-projection x-ray and TV up to 80 per year and that of punctures controlled by CT up to 150 per year. Individual dosimetric control is obligatory for physicians regularly engaged in this type of investigations.

[Massive hemorrhage following multiple epidural punctures as a late complication in thrombocythemia].

We present a female patient in whom numerous lumbar punctures for epidural anaesthesia were followed by a delayed development of a large subcutaneous haematoma in the lumbar region. The outcome was fatal. The patient's basic disease was found to be chronic myeloic leukaemia that had caused an excessive elevation of platelet count. We, therefore, suggest that lumbar punctures for epidural anaesthesia should be approached with extreme care in cases of thrombocytaemia. If possible, repeated punctures for the placement of epidural catheters should be avoided.

[Technic of exact lung puncture].

The accuracy can be improved, and the risk of complications can be reduced in the case of cytodiagnostic lung puncture, if one optimises the method whereby the puncture needle is inserted into the lesion. The author describes such a procedure incorporating the use of technical aids for marking the exact puncture point of the cannula. At the same time the procedure results in a reduction of radiation exposure of both doctor and patient.

[Lymphography and fine needle puncture biopsy in the evaluation of lymph node involvement. Apropos of 207 cases].

Percutaneous fine needle puncture biopsy was performed on lymph nodes taking up contrast during lymphography in 207 patients with various disorders: urogenital (174 cases), gynecologic (13 cases), hematologic (17), others (3). At the present time, in fact, and simultaneously with the development of physical methods of diagnostic exploration (ultrasonography, computed tomography) needle puncture biopsy has become of increasing importance to confirm a suspected diagnosis. Needle puncture biopsy under television control is a simple, painless and practically nontraumatic procedure. When performed under precise conditions and a strict methodology (routine sampling as a function of the primary glandular chains), it establishes the correct diagnosis in a large number of lymphographies, enabling a rapid and more precise evaluation of the degree of extension and thus a better therapeutic choice.

[Indication and diagnostic value of roentgen-guided fine-needle puncture of space-occupying renal lesions (author's transl)].

Roentgen-guided fine needle puncture of space-occupying renal lesions as an important additive radiologic procedure is able to solve differential diagnostic problems of liquid or solid renal lesions in a quick, accurate and safey way. It rules out a solid neoplasm, provides the surgeon with a maximum of preoperative information and helps to avoid operations on aged and other poor-risk patients. After description of the puncture technique we report the result of 217 fine needle punctures of the kidney over 13 years.

[Is renal cyst puncture an available diagnostic procedure for differentiation of avascular, space-occupying renal lesions? (author's transl)].

Renal cyst puncture as an important, additive radiologic technique is able to solve differential diagnostic problems of avascular, space-occupying renal lesions in a quick, accurate, and safe way. Renal cyst puncture rules out a solid neoplasm and provides the surgeon with a maximum of preoperative information. Through its use unnecessary operations on aged and poor-risk patients can be avoided. The method is described, and the results of 185 finegauge needle punctures of the kidney obtained from 2329 renal angiographies over 11 years, are reported.

[Etiological diagnosis of hepatic masses by percutaneous puncture guided by ultrasonics. Study carried out in patients without known neoplasms].

Ultrasonically guided liver puncture was carried out in 26 patients without overt carcinoma, who presented with a small intrahepatic mass giving an ultrasonographic image of primary or secondary tumour. Puncture was performed with a lumbar or a Chiba needle under local anaesthesia, and a real-time ultrasound apparatus with guide was used. The specimens collected were fixed on slides for histological examination. An aetiological diagnosis was made in 73% of the cases (16 carcinomas and 3 liver abscesses). No abnormal cells were detected and further investigations were conducted in 15%. The failure rate was 12% (2 punctures without specimens and 1 false-negative result). No infectious or haemorrhagic complication was observed.
