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.     

Copper deficiency during parenteral nutrition: a report of four pediatric cases.

The standard of care for patients with cholestasis (direct bilirubin >or=2 mg/dL) while receiving parenteral nutrition (PN) solutions is to reduce or discontinue the copper and manganese. The repercussions of this action have not been studied. Two adult case reports document low serum copper levels associated with clinical symptoms of copper deficiency after the removal of copper from their PN solutions. We now describe the first known series of pediatric patients to develop copper deficiency after copper was removed from their PN solutions.     

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.     

The anatomical course of the neurovascular bundles in epispadias

References on the anatomical course of the neurovascular bundles of the penis in epispadias are rare. We studied the anatomy of the neurovascular bundles in 5 patients undergoing primary epispadias repair and 13 adolescents undergoing correction of erectile deformities. In all primary cases the neurovascular bundles were truly lateral as they ran along the distal and middle portions of the corporeal bodies, and became anterolateral only proximally. The bundles were identified in only 5 of 13 secondary cases and were in the same position as in the primary cases. Knowledge of this anatomy is important to protect these structures from surgical injury in cases of epispadias and exstrophy.     

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.     

Narcosuggestion in chronic conversion symptoms using combined intravenous amobarbital and methylphenidate

Five patients with chronic conversion symptoms were treated with narcoanalysis and narcosuggestion using combined methylphenidate and amobarbital. The combination of methylphenidate and amobarbital proved useful because methylphenidate antagonized sedation and allowed optimal patient cooperation. In four cases recovery of neurological function was obtained in the first or second interview and subsequently improved with practice and positive feedback. In each instance recovery of neurological function during a narcoanalytic interview confirmed the diagnosis of a conversion reaction. The narcoanalytic interview also confirmed or uncovered important psychopathology and psychodynamics which permitted more accurate treatment of the underlying psychiatric disorders.     

AIDS and South Africa--towards a comprehensive strategy. Part II. Screening and control

In this, the second of a three-part series of articles in which we propose steps towards a comprehensive strategy for the control of HIV infection, we consider controversies relating to screening for HIV, the indications for and desirability of mandatory testing of certain groups at risk, and the place of voluntary testing in the control of HIV transmission and infection. Key recommendations are that mandatory testing of donors of blood and other vital tissues, patients on haemodialysis and haemodialysis unit staff is justified, and that children put up for adoption may require testing. We make further recommendations regarding HIV testing as a prerequisite for life insurance and recommend that voluntary testing be offered, supported by adequate pre- and post-test counselling. We consider that all health care workers should accept as their moral obligation the care and management of HIV-infected individuals, and that they should be adequately educated and skilled in such work. These recommendations were reached largely by consensus, although there were occasions when individual authors condoned recommendations with which they did not personally agree.
