Intensive retreatment of adults and children with acute lymphoblastic leukemia.

Twenty-three patients (16 adults) failing their first or subsequent (n = 8) intensive treatment for de novo acute lymphoblastic leukemia (ALL) and chronic myeloid leukemia lymphoid blast phase (n = 2) were managed with protocol POG 8201, originally introduced in relapsed ALL of childhood. In this programme, a four-drug induction phase is followed by early consolidation with teniposide-cytarabine, intrathecal chemotherapy, continuation weekly chemotherapy alternating teniposide-cytarabine with vincristine-cyclophosphamide, and periodic reinduction courses. Fourteen adults and five children with ALL achieved a complete response (CR) (86 per cent). The highest response rate (100 per cent) was obtained in 12 patients treated at first relapse after an initial CR of greater than 18 months (p = 0.07). Median duration of CR was 8 months in adults and 11 months in children. A longer than previous one CR (inversion) was obtained in four cases. Four ALL patients were successfully transplanted from a matched sibling after 3-11 months from achievement of CR. Median overall survival in adults with ALL was 11 months, significantly longer than for 40 comparable cases treated intensively but without rotational continuation therapy in previous years (p less than 0.001). This regimen is applicable to adults with relapsed ALL, where prolongation of survival may allow time for effective salvage with bone marrow transplantation.     

Treatment of dual diagnosis patients: A relapse prevention group approach

The authors describe the successful use of an adjunctive group psychotherapy for substance-abusing patients with major psychiatric disorders (bipolar, schizophrenia, schizoaffective, psychotic depression, and atypical psychosis). The group utilizes a psychoeducational approach that focuses on substance abuse causes and consequences, principles of recovery, and relapse prevention strategies. Eight patients with prolonged histories of abuse of cocaine, alcohol, marijuana, or other drugs were enrolled in this weekly group treatment at a community mental health center drug treatment program, while continuing in treatment with their current case manager or primary therapist. Six of the eight patients achieved periods of stable abstinence, documented by self-report, urine toxicology screens, continued group attendance, and improved social functioning. Case examples are utilized to illustrate the group process.     

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.

The 1989 report of the North American Pediatric Renal Transplant Cooperative Study

This report of the North American Pediatric Transplant Cooperative Study summarizes data contributed by 57 participating centers on 754 children with 761 transplants from 1 January 1989 to 16 February 1989. Data collection was initiated in October 1987 and follow-up of all patients is ongoing. Transplant frequency increased with age; 24% of the patients were less than 5 years, with 7% being under 2 years. Common frequent diagnoses were: aplastic/dysplastic kidneys (18%), obstructive uropathy (16%), and focal segmental glomerulosclerosis (12%). Preemptive transplant, i.e., transplantation without prior maintenance dialysis, was performed in 21% of the patients. Dialytic modalities pretransplant were peritoneal dialysis in 42% and hemodialysis in 25%. Bilateral nephrectomy was reported in 29%. Live-donor sources accounted for 42% of the transplants. Among cadaveric donors, 41% of the donors were under 11 years old. During the first post-transplant month, maintenance therapy was used similarly for live-donor and cadaver source transplants, with prednisone, cyclosporine, and azathioprine used in 93%, 83%, and 81%, respectively. Triple therapy with prednisone, cyclosporine, and azathioprine was used in 78%, 75%, and 75% of functioning cadaver source transplants at 6 months, 12 months, and 18 months as opposed to 60%, 63%, and 54% for live-donor procedures, with single-drug therapy being uncommon. Rehospitalization during months 1–5 occurred in 62% of the patients, with treatment of rejection and infection being the main causes. Additionally, 9% were hospitalized for hypertension. During months 6–12 and 12–17, 30% and 28% of the patients with functioning grafts were rehospitalized. Times to first rejection differed significantly for cadaver and live-donor transplants. The median time to the first rejection was 36 days for cadaver transplants and 156 days for live-donor transplants. Overall, 57% of treated rejections were completely reversible although the complete reversal rate decreased to 37% for four or more rejections. One hundred and fifty-two graft failures had occurred at the time of writing, with a 1-year graft survival estimate of 0.88 for live-donor and 0.71 for cadaver source transplants. In addition to donor source, recipient age is a significant prognostic factor for graft survival. Among cadaver donors, decreasing donor age is associated with a decreasing probability of graft survival. Thirty-five deaths have occurred; 16 attributed to infection and 19 to other causes. The current 1-year survival estimate is 0.94. There have been 9 malignancies.A list of all participating centers and the names of the investigators is printed on pages 552–553     

A Case of a Patient with a Rectal Ulcer Who Had an Unusual Defecation Habit

Abstract: This case report describes a patient with a rectal ulcer who had an unusual defecation habit. Complete healing was recognized colonoscopically after the patient was instructed to break this habit. A polyp of the ascending colon was detected by a barium enema in a 37-year-old man complaining of anal bleeding. He was admitted to our division to undergo a polypectomy. At the time of the polypectomy, a round ulcer, measuring 1 cm in diameter, was detected on the right wall of the rectum 3 cm from the anal verge. A diagnosis of mucosal prolapse syndrome of the rectum could not be made because the patient did not exhibit the characteristic habit of excessive “straining” mentioned by patients with this syndrome, and no characteristic finding of fibromuscular obliteration was found on histological examination of biopsied specimens taken endoscopically from the lesion. Repeated history taking, however, revealed that the patient had the unusual habit of inserting his finger into his rectum after defecation. He broke this habit following instruction to do so. As a result, on colonoscopic examination 15 month later, the ulcer was found to have become a scar:     

Leishmaniasis of the lip in a patient with Down''s syndrome

Cutaneous leishmaniasis is an endemic protozoan infection in Sardinia, one of the major islands of the Mediterranean Basin. The main causative strain in this country is Leishmania infantum, which rarely involves mucocutaneous areas, but has the potential to cause visceral leishmaniasis. An atypical leishmaniasis involving the inferior lip of a 57-year-old female with Down's syndrome was observed at the Dermatology Department of Cagliari (italy). The diagnosis was mainly based upon histopathological examination, revealing intra- and extra-cellular leishmania amastigotes. The leishmania infantum zymodeme MON-111 was identified by isoenzymatic characterization. Laboratory investigations revealed a normal complete blood count and biochemistry profile, except for an inverted CD4/CD8 ratio. Treatment with meglumine antimoniate 60 mg/kg/day (Glucantime) intramuscularly for 15 days, followed by intralesional administration 1 ml weekly for 4 weeks led to complete recovery. No relapses were observed at 6-month follow-up. The unusual localization is likely to be a reflection of the uncommon site of inoculation of the protozoa, transmitted by bites from flying vectors. Nevertheless, the presence of Down's syndrome in our patient may have contributed to the atypical presentation by traumatic exacerbation of the lesion, due to repeated auto-induced microtraumas of the inferior lip accompanied by subclinical immunodeficiency. In fact, the specific immune response to Leishmania infection depends on a host-cell-mediated immune response, reported as defective in Down's syndrome patients. Differential diagnosis and early detection of the infection are necessary in order to start effective treatment and prevent more serious complications.     

Analgesic nephropathy in Hungary: the HANS study.

BACKGROUND: The diagnosis of analgesic nephropathy has improved significantly with modern imaging techniques. We reviewed a large portion of the Hungarian dialysis population to obtain additional insight into the problem. METHODS: Twenty-two participating dialysis units enrolled 1400 patients on renal replacement therapy between 1 January 1995 and 1 January 1998. Patients with no known aetiology (n = 284) were interviewed and studied with renal imaging. We assessed the presence of decreased renal mass combined with either bumpy contours, papillary calcification, or both. The subjects studied were interrogated extensively. RESULTS: Our survey suggested analgesic nephropathy in 47 of 1400 patients (3.3%), 3-fold higher than the EDTA database estimate for Hungary. The analgesics most commonly abused were phenacetin-containing mixtures. The driving symptoms were mainly headache and joint pain. Cardiovascular complications were more common than in the rest of the dialysis population, independent of smoking and lipid values (P<0.01). CONCLUSIONS: Phenacetin should be banned. Our study results support the need for longitudinal cohort and case-control studies in Hungary.     

Photodynamic therapy and photodiagnosis for Barrett''s oesophagus and early oesophageal carcinoma

Over the last few decades the there has been a huge increase in the incidence of oesophageal adenocarcinoma, surpassing that of any other solid tumour. Barrett's oesophagus is recognised as a pre-malignant cursor. Surveillance programmes have evolved to monitor Barrett's oesophagus, with the intention to detect early malignant transformation. Using photosensitive agents photodiagnosis is developing to detect this transformation before it is visible endoscopically to allow early treatment. Photodynamic therapy is a non-thermal endoscopic ablative technique, which incorporates the same photosensitive agents to treat Barrett's oesophagus as well as malignant disease. In this article we review the present status of photodiagnosis and photodynamic therapy in the management of Barrett's oesophagus and early oesophageal carcinoma.     

Long term group psychotherapy with (near) psychotic children

Traditionally, psychotherapy groups for children included only relatively intact youngsters. This paper describes a group consisting of four (near) psychotic children and two co-therapists which met for over three years. The developmental changes which occurred in the group over the course of time will be identified and discussed using a neo-psychoanalytic, object relations framework.
