Free vascularized jejunum interposition for pharyngoesophageal reconstruction after total laryngopharyngectomy

The records of 28 patients who underwent free jejunal graft reconstruction after resection for cancer involving the pharynx were analysed. Seven patients had a T₃ carcinoma, 15 patients T₄ and six patients recurrence after laryngectomy. Ten patients had received radiotherapy in the past. Post-operatively, 15 patients (54%) had complications and two patients (7%) died. No significant difference was observed in the complication rate between the group that received radiotherapy in the past and those who did not. Nineteen patients received post-operative radiotherapy. Nine patients had no radiotherapy on the basis of complete resection or because of serious complications. For the whole group the 2-year recurrence free period and survival were 42% and 51% respectively. The postoperative radiotherapy group had a significantly better survival (73%) and recurrence free period (63%) than the group without post-operative radiotherapy (0%). Thus, post-operative radiotherapy seems indicated irrespective of resection margins.     

Combined transrectal ultrasonography and urodynamics in the evaluation of detrusor-sphincter dyssynergia

Thirty-one combined transrectal ultrasonographic and urodynamic studies were performed in 24 patients with spinal cord lesions at different levels between C4 and T12. Ultrasonography provided accurate real-time imaging of the bladder neck, prostatic urethra and external sphincter during the bladder filling phase as well as during the voiding phase. Bladder and rectal pressures, sphincter EMG and uroflow were recorded simultaneously. Transrectal ultrasonography contributed significantly to the accuracy of diagnosing detrusor-sphincter dyssynergia. Sphincter contractions were clearly visualised with ultrasonographic video monitoring. This imaging method was especially helpful in sorting out the problems of 3 patients with poor emptying of bladder after endoscopic sphincterotomy. One had a urethral stricture and the other 2 had sphincters that opened adequately but bladders that emptied poorly because of detrusor hypocontractility. Other problems, such as benign prostatic hyperplasia and false passage, were also easily recognised. Transrectal ultrasonography not only provides accurate information but also involves no exposure to radiation and thus precludes the need for costly lead-shielded examination rooms.     

Mechanisms and patient compliance of dust-mite avoidance regimens in dwellings of mite-allergic rhinitic patients

We report on the mechanisms, the environmental changes and patient compliance with regard to conventional and new dust and mite avoidance measures to prevent allergic symptoms caused by mite allergens, taking into account both allergen contamination and the developmental success of pyroglyphid Acari. Twenty patients with persisting rhinitic complaints were selected and matched. Although the patients had performed some conventional dust and mite avoidance measures (patient compliance was 90%), the dwellings proved to be a stimulus for mite development. Moisture problems due to faulty construction and excessive moisture production were common. Since humidity conditions could not be changed at short notice, the 20 homes were subjected to the new variants of mite allergen avoidance based on intensive cleaning without (control) and with an acaricide incorporated (acaricidal cleaner [Acarosan]). After the carrying out of conventional avoidance measures, these patients still had allergic symptoms, and dust from only 23 to 52% of their textile objects was under the proposed guanine (mite faeces indicator) risk level. Only the acaricidal cleaner was able to decrease the allergenic mite load (and the burden of the patients) significantly in this 12 month period. With respect to mite-extermination, acaricidal cleaning was 88% better than intensive cleaning. Reduction of guanine was 38% better in the Acarosan treatment group. Clinical results have been reported elsewhere. A significant difference in favour of the acaricidal cleaning was seen in both subjective (as regards symptoms) and in objective data (total IgE). Another 50 patients were questioned. About 90% were willing to spend two weekends (70%), or at the most one weekend (20%) per year sanitizing the dwelling by cleaning it with the whole family. The authors of this report consider acaricidal cleaning to be a significant improvement in the management of mite-allergic diseases, such as rhinitis. Compared with the replacement of home textiles, this treatment is less expensive and more effective. Patient compliance is acceptable, but depends on acceptance by physicians and the initial motivation and consequent burden on the patient.     

Cardiac tamponade after intrapericardial diaphragmatic hernia

An unusual case of intrapericardial diaphragmatic hernia ispresented. Cardiac tamponade occurred in the operating roomsoon after induction of anaesthesia. Surgical removal of theherniated omentum and stomach allowed haemodynamic improvement.The pathophysiology is discussed and patients with cardiac tamponadereviewed.
