Duration of dysmenorrhoea and extent of adenomyosis visualised by magnetic resonance imaging

OBJECTIVE: Enlargement of the junctional zone (JZ) on T2-weighted resonance imaging of the uterus has recently been established as the major criterion for adenomyosis in patients with endometriosis. This study was conducted to analyse the extent of adenomyosis using magnetic resonance imaging (MRI) and relate it to the duration of dysmenorrhoea. STUDY DESIGN: This was a prospective study of 70 patients presenting with the complaint of severe dysmenorrhoea. Forty patients (57%) reported dysmenorrhoea as their major complaint and 30 patients (43%) suffered additionally from infertility. Group I (n=40) consisted of patients with dysmenorrhoea of between 1 and 10 years' duration, group II (n=30) consisted of patients with dysmenorrhoea of longer than 11 years' duration. All patients underwent laparoscopy to detect the presence and degree of endometriosis, and all patients underwent T2-weighted resonance imaging of the uterus to detect the extent of adenomyosis by measurement of the "junctional zone". RESULTS: In group I, adenomyosis could be detected via MRI in 21 patients (52.5%), while 19 patients (47.5%) showed no signs of adenomyosis. By contrast, in group II a distinct enlargement of the JZ, as the major radiological criterion of adenomyosis, could be observed in 26 patients (87%), while only 4 patients (13%) revealed no signs of adenomyosis (p=0.04). The mean thickness of the JZ was significantly enlarged in group II (11.07 mm) compared with group I (6.38 mm; p<0.0001). The prevalence of adenomyosis in endometriosis after dysmenorrhoea of more than 11 years' duration was 87%. CONCLUSIONS: In deep infiltrating endometriosis, a correlation between a specific localisation and dysmenorrhoea can often not be found. Recently, endometriosis and adenomyosis have been believed to result from a common uterine disease, the dislocation of the basal endometrium. Our data clearly show that dysmenorrhoea of long duration in patients who have had endometriosis for over a threshold value of 11 years is significantly related to adenomyosis of the uterus. Hence, evaluation of adenomyosis using MRI should become a standard procedure in cases of dysmenorrhoea and endometriosis. Severe dysmenorrhoea of long duration should always focus clinical interest on adenomyosis of the uterus.     

Operative Therapie bei skapholunären Bandverletzungen

Background

The purpose of this work was to retrospectively evaluate clinical and radiological results after surgical treatment for scapholunate ligament ruptures.

Materials and methods

Measurements of range of motion, strength, and angles, as well as postoperative score assessments were performed in 32 patients.

Results

The average mobility in the operated wrist was 52° for flexion, extension 57°, radial 24°, ulnar deviation 31° and forearm rotation outward 88° and inward 89°. The recovery of force was 89?% compared with the healthy hand. It showed an average skapholunar angle of 63°, a radioulnar angle of 22° and an average carpal height according to Nattrass of 1.49. Our patients rated the operation result with a median DASH score of 11 points (range 0–70.8 points). The median objective Mayo Wrist Score was 80 points (range 45–100 points).

Conclusion

Surgical treatment of scapholunate ligament rupture, especially against the background of carpal collapse, is a very satisfactory method with very good results in the objective function and strength, and a high level of patient satisfaction.     

Preliminary experience with transarterial chemoembolization (TACE) in liver metastases of uveal malignant melanoma: local tumor control and survival

Purpose To evaluate results in the palliative treatment of patients with liver metastases of uveal malignant melanoma using transarterial chemoembolization (TACE). Materials and methods Superselective TACE was repeatedly performed in 12 patients with liver metastases of uveal malignant melanoma. Six patients presented with solitary liver metastases (6–12 cm in size) and six patients with oligonodular metastases (n ≤ 6). The embolization suspension consisted of a maximum of 10 mg/m² Mitomycin C, 10 ml Lipiodol, and an injection of 200–450 mg resorbable microspheres for vascular occlusion. In the follow-up, magnetic resonance imaging was performed in 3-month intervals. Results The TACE procedure was well tolerated in all patients without any relevant side effects. Three patients responded to TACE with a size reduction of more than 50% (partial response), five patients with stable disease, and four patients with progressive disease with an increase in volume of more than 25%. Mean survival following primary tumor treatment was 32.9 months, and after first embolization 19.5 months. Lower survival rates were recorded for the progressive group (16.5 months). Conclusion Repeated TACE offers a palliative treatment option in patients with oligonodular liver metastases of uveal malignant melanoma.     

Treatment of unresectable lung metastases with transpulmonary chemoembolization: preliminary experience

Transpulmonary chemoembolization (TPCE) was evaluated as a new treatment for unresectable lung metastases. Institutional review board approval and patient consent were obtained. In 23 patients, 26 lung metastases of different origins were treated locally by using a transpulmonary approach. After femoral vein puncture, tumor-supplying pulmonary arteries were selectively explored, and 5-10 mg mitomycin C and 5-10 mL iodized oil and microsphere particles were applied with balloon protection. Diagnosis and follow-up (3-month intervals) were performed with unenhanced and contrast material-enhanced computed tomography (CT). Treatment was well tolerated in all patients, with no major side effects or complications. As indicated by using morphologic criteria, volume regression of embolized areas was achieved in eight patients, while stable disease was revealed at follow-up in six patients. In nine patients, progression of treated intrapulmonary metastases was recorded. TPCE could be a well-tolerated palliative treatment option in patients with pulmonary metastases.     

Traumatic injuries of the pelvis and thoracic and lumbar spine: does thin-slice multidetector-row CT increase diagnostic accuracy?

The objective is to evaluate different multidetector-row CT (MDCT) strategies for adequate classification of spinal and pelvic injuries. Seventy intubated patients after multiple trauma underwent conventional radiography (CR) and MDCT. Examinations included the pelvis (P), the lumbar spine (LS) and the thoracic spine (TS). Conventional radiographs, 3-mm (CT5) and 5-mm scans (CT3) and 3-mm and 5-mm scans combined with MPR (CT3R/CT5R) were compared to surgery, autopsy and clinical course. MDCT led to significantly better results than CR (P<0.01). Correlation coefficients were r=1.0 (CT3R), r=0.96 [TS] to r=1.0 [P/LS] (CT5R), r=0.8 [P] to r=1.0 [TS] (CT3), r=0.80 [P] to r=0.86 [TS] (CT5) and r=0.3 [TS] to r=0.69 [P] (CR). Fractures were identified by CT3R in 100% of cases, by CT5R in 95%, by CT3 in 90% [P]–100% [TS], by CT5 in 83.3% [LS]–90% [P] and by CR in 57.1% [TS]–87.2% [P]. Unstable fractures were identified in 100% by CT3R, CT5R and CT3, 85.7% [TS]–100% [P/LS] by CT5 and 57.1% [TS]–80% [P] by CR. Only overlapping thin-slice multiplanar reformation allows for an adequate classification of spinal and pelvic injuries and thus is highly emphasized in patients after severe blunt trauma.     

Laserinduzierte Thermotherapie von Lungenmetastasen und primären Lungentumoren

We present laser-induced thermotherapy (LITT) of primary and secondary lung tumors analysing indications and technical concepts. Thirty patients with lung metastases of different primary tumors (n=24) as well as localized lung tumors (n=6) were prospectively treated in 41 sessions using laser-induced thermotherapy (LITT). An MR-compatible puncture system was used with direct puncture technique. The puncture was performed via CT guidance in care vision technique. Eight patients were thermoablated using MR tomographical monitoring, 22 patients using CT monitoring. Local therapy effects, tumor control rate, side effects, complications, and survival were evaluated. In 74% of cases (28/38 lesions) of 24 patients with lung metastases and in all cases of the 6 patients with lung carcinoma a complete local ablation could be achieved. The complication rate (pneumothorax) was 9,8%. One patient with bronchial carcinoma had to be thoracotomized and resected. 93% of the patients are still alive. Percutaneous LITT of lung tumors permits a complete ablation of lung metastases and lung carcinomas with a low complication rate. Indications for the procedure were defined for patients with no more than 5 metastases up to 3 cm in size.     

Transarterielle Chemoembolisation (TACE) von Lebermetastasen – Ein palliativer Therapieansatz

Metastatic involvement of the liver determines the treatment. Hepatic artery chemoembolization (TACE) represents a safe palliative treatment for patients with unresectable liver metastases. Technical treatment, indication and results of the TACE are reported. The results of TACE depend on primary cancer, size and vascularisation of the hepatic tumors. Our results with out patient treatment of 245 patients prove that TACE results in a extremely low rate of side effects. Combination of TACE with local ablative treatment may present potentially curative treatment option for unresectable tumors.
