A multiple-site perineal applicator (MUPIT) for treatment of prostatic,anorectal, and gynecologic malignancies

Recently, transperineal interstitial-intracavitary applicators have been used to treat locally limited and advanced perineal and gynecologic malignancies. We have developed a single afterloading applicator, referred to as the “MUPIT” (Martinez Universal Perineal Interstitial Template), which with its prototypes has been utilized to treat 78 patients with malignancies of the cervix, vagina, female urethra, perineum, prostate, and anorectal region. The device basically consists of two acrylic cylinders, an acrylic template with a predrilled array of holes that serve as guides for trocars, and a cover plate. Some of the guide holes on the template are angled outward to permit a wide lateral coverage without danger of striking the ischium. The cylinders have an axial hole large enough to pass a central tandem or a suction tube for the drainage of secretions. Thus, the device allows for the interstitial placement of ¹⁹²Ir ribbons as well as the intracavitary placement of either ¹³⁷Cs tubes or ¹⁹²Ir ribbons. In use, the cylinders are placed in the vagina and rectum and then fastened to the template, so that a fixed geometric relationship among the tumor volume, normal structures, and source placement is preserved throughout the course of the implantation. Howlow, closed-end, stainless steel trocars are then inserted through the guide holes that produce optimal coverage of the treatment volume. Appropriate computer programs also have been developed on a minicomputer for the corresponding dose-rate computations. These programs run with sufficient speed that they may be used for both the planning of the source placement beforehand and the computation of the actual dose-rate distribution obtained. The advantages of the system are (1) greater control of the placement of sources relative to the tumor volume and critical structures owing to the fixed geometry provided by the template and cylinders, and (2) improved dose-rate distributions obtained by means of computer-assisted optimization of the source placement and strength during the planning phase.     

Temporal lobe lesions in head injury

Summary In cases of closed head injury temporal lobe lesionse.g. contusion, laceration, pulping, or intracerebral haematoma frequently result in an expanding process. These are frequently associated with an overlying subdural haematoma. Eighty five cases of such lesions from a consecutive series of 1,000 cases of head injury have been analyzed. The lesions are caused by severe injury resulting in loss of concsiousness and skull fracture. Most of them are contre-coup lesions. Clinically they manifest themselves like any other acute or subacute intracranial hematoma. The majority of the patients have contralateral hemiparesis and pupillary abnormalities. Carotid angiography is valuable for diagnosis. These lesions are likely to be missed when exploratory burr holes are made or, are erroneously diagnosed as acute subdural haematoma or brain oedema. Smaller lesions, not showing progressive deterioration, may respond to conservative treatment. However, surgical decompression is essential in most cases. A fronto-temporal osteoplastic craniotomy or a large Scoville trephine hole is essential to deal with these lesions adequately.     

Is ultrasound really helpful in the detection of rib fractures?

OBJECTIVE: To determine the usefulness of ultrasound in the detection of rib fractures. PATIENTS AND METHODS: A prospective study was performed over a 3-month period. Patients presenting with a high clinical suspicion of rib fracture(s) to the Accident and Emergency Department were referred for radiological work-up with a PA chest radiograph, an oblique rib view and a chest ultrasound. Associated lesions, e.g. pleural effusion, splenic laceration and pneumothorax were recorded. RESULTS: Fourteen patients were radiologically assessed. The mean patient age was 31 years (range 16-55 years) and the M:F ratio 3.7:1 (11 men and 3 women). Ten patients displayed a total of 15 broken ribs. Chest radiography detected 11, oblique rib views 13 and ultrasound 14 broken ribs. Ultrasound findings included discontinuity of cortical alignment in 12 fractures, an acoustic linear edge shadow in nine and a reverberation artifact in six. Concordance with plain film findings, and especially oblique rib views, was good, though better when the rib fractures fragments were markedly displaced. One splenic laceration was detected with an associated small pleural effusion. There were no pneumothoraces. The average time of ultrasound examination was 13 min. CONCLUSION: Ultrasound does not significantly increase the detection rate of rib fractures, may be uncomfortable for the patient and is too time-consuming to justify its routine use to detect rib fractures.     

Successful management of concommitant blunt injury to the trachea, esophagus, and cervical spine in a 6-year-old girl

A 6-year-old girl sustained an unusual constellation of injuries after blunt trauma sustained in a motor vehicle accident. Transection of the trachea and esophagus were managed successfully by repair through a median sternotomy while the patient was on cardiopulmonary bypass. A cervical spinal injury was fixated with halo traction and a femur fracture with internal fixation.     

Pelvic floor muscle strength and thickness in continent and incontinent nulliparous pregnant women

The aim of the study was to measure pelvic floor muscle function in continent and incontinent nulliparous pregnant women. The study group consisted of 103 nulliparous pregnant women at 20 weeks of pregnancy. Women reporting urinary incontinence once per week or more during the previous month were classified as incontinent. Function was measured by vaginal squeeze pressure (muscle strength) and increment in thickness of the superficial pelvic floor muscles (urogenital diaphragm) assessed by perineal ultrasound. Seventy-one women were classified as continent and 32 women as incontinent. Continent women had statistically significantly higher maximal vaginal squeeze pressure and increment in muscle thickness when compared with incontinent women. There was a strong correlation between measurements of vaginal squeeze pressure and perineal ultrasound measurements of increment in muscle thickness. This study demonstrates statistically significant differences in pelvic floor muscle function measured by strength and thickness in continent compared with incontinent nulliparous pregnant women. Editorial Comment: This study evaluated pelvic floor muscle function in 103 nulliparous continent and incontinent women at 18–20 weeks gestation. Pelvic floor muscle strength was assessed by measuring vaginal squeeze pressure, and thickness of the urogenital diaphragm during both relaxation and contraction was measured using perineal ultrasound. The authors found a statistically significant higher vaginal squeeze pressure and higher mean increment in muscle thickness in the continent compared with incontinent group as well as a strong correlation between pelvic floor muscle strength and increment in thickness. Although describing several benefits of ultrasonography in assessing pelvic floor muscles, the authors did acknowledge the difficulty in identifying and measuring these muscles, and the learning curve involved with perineal ultrasound. Another limitation was the subjective classification of continence status based on self-reported symptoms. The implication of low pelvic floor muscle strength and thickness as risk factors for the development of urinary incontinence is beyond the scope of this study.     

Successful Treatment of Fournier’s Gangrene with the Assistance of Preoperative Computed Tomography in an Elderly Man: Report of a Case

An 87-year-old man presented with inguinal pain and swelling, and was later diagnosed as having Fourniers gangrene. The information gained from preoperative computed tomography (CT) proved very useful for defining the extent of necrosis, and emergency surgery saved his life. Thus, CT should be performed prior to treatment of Fourniers gangrene, even in an emergency situation.

How does tension-free vaginal tape correct stress incontinence? Investigation by perineal ultrasound

Forty patients who underwent a single tension-free vaginal tape procedure were evaluated by perineal ultrasound both pre- and postoperatively in a prospective observational clinical study. The positions of the tape, bladder neck and urethra were sonographically documented at rest and during Valsalva maneuvers. During Valsalva the tape rotated towards the symphysis in all patients. Postoperative urethral angulation could be demonstrated in 36 of 40 patients. Bladder neck mobility remained unchanged after the tension-free vaginal tape procedure, and 36 of the 40 were dry according to patient questionnaires. Postoperative cough test was negative in all patients. Two points seem to be important for the functioning of the tension-free vaginal tape: a dynamic kinking of the urethra during stress, and the movement of the tape against the symphysis, compressing the tissue between the tape and the symphysis. Mobility of the bladder neck is unaffected by the single tension-free vaginal tape procedure.Abbreviations TVT Tension-free vaginal tape - UVJ Urethrovesical junction Editorial Comment: The authors are to be commended for an interesting study using perineal ultrasound imaging for evaluation of TVT placement and function. The study demonstrates two main functions of the tape: midurethral kinking, and compression of the tape against the symphysis pubis. This agrees with published imaging data and confirms the essentially obstructive function of the TVT.

Timing of surgery in perineal ectopic testes: analysis of 16 cases

 Between 1993 and 1998, 16 patients with perineal ectopic testes (PET) (1%) were diagnosed among the 1,576 patients operated upon for undescended testes (UDT) in two pediatric surgical centers. The mean age was 23 ± 22.5 months. The clinical presentation was an empty scrotum with an ipsilateral palpable perineal mass in 16 patients and an inguinal hernia in 5. In all except 1 patient whose atrophic testis was removed, orchiopexy into the dartos pouch was easily performed through a standard inguinal skin-crease incision. The length of the testicular vessels and vas deferens was adequate and retroperitoneal dissection was not required. Although the complications of UDT are the same as for PET, the timing of surgery should be different. It is generally accepted that children must not be below 6 months of age for surgical correction of UDT, but there is no need to delay surgery in PET, which can easily be diagnosed by physical examination in the neonatal period. Surgery is indicated even if there is no hernia present. Accepted: 14 April 2000
