Benign intracranial hypertension and recombinant growth hormone therapy in Australia and New Zealand

Benign intracranial hypertension (BIH) is reported in three children from Australia and one from New Zealand, who were being treated with recombinant human growth hormone (rhGH). Three males and one female, aged between 10.5 and 14.2 y, developed intracranial hypertension within 2 weeks to 3 months of starting treatment. A national database, OZGROW, has been prospectively collecting data on all 3332 children treated with rhGH in Australia and New Zealand from January 1986 to 1996. The incidence of BIH in children treated with growth hormone (GH) is small, 1.2 per 1000 cases overall, but appears to be greater with biochemical GHD (<10IUml ^-1), i.e. 6.5/1000 (3 in 465 cases), relative risk 18.4, 95% confidence interval 1.9-176.1, than in all other children on the database. The incidence in patients with Turner's syndrome was 2.3/1000 (1 in 428 cases). No cases in patients with partial GHD (10–20 IUml ^-1) or chronic renal failure were identified. Possible causative mechanisms are discussed. The authors'practice is now to start GH replacement at less than the usual recommended dose of 14IUm-² week^-1 in those children considered to be at high risk of developing BIH. Ophthalmological evaluation is recommended for children before and during the first few months following commencement of rhGH therapy and is mandatory in the event of peripheral or facial oedema, persistent headaches, vomiting or visual symptoms. The absence of papilledema does not exclude the diagnosis.     

Bovine colostrum immunoglobulin concentrate for cryptosporidiosis in AIDS.

Lactobin-R is a commercial hyperimmune bovine colostrum with potent anticryptosporidial activity. It was administered to a 4 year old child with AIDS and severe diarrhoea associated with cryptosporidiosis. There was significant clinical improvement in the diarrhoea and permanent elimination of the parasite from the gut as assessed through serial jejunal biopsy and stool specimens.     

Quality indicators for primary care mental health services

Objectives: To identify a generic set of face valid quality indicators for primary care mental health services which reflect a multi-stakeholder perspective and can be used for facilitating quality improvement.

Design: Modified two-round postal Delphi questionnaire.

Setting: Geographical spread across Great Britain.

Participants: One hundred and fifteen panellists representing 11 different stakeholder groups within primary care mental health services (clinical psychologist, health and social care commissioner, community psychiatric nurse, counsellor, general practitioner, practice nurse/district nurse/health visitor, psychiatrist, social worker, carer, patient and voluntary organisations).

Main outcome measures: Face validity (median rating of 8 or 9 on a nine point scale with agreement by all panels) for assessing quality of care.

Results: A maximum of 334 indicators were rated by panels in the second round; 26% were rated valid by all panels. These indicators were categorised into 21 aspects of care, 11 relating to general practices and 10 relating to health authorities or primary care groups/trusts. There was variation in the total number of indicators rated valid across the different panels. Overall, GPs rated the lowest number of indicators as valid (41%, n=138) and carers rated the highest number valid (91%, n=304).

Conclusions: The quality indicators represent consensus among key stakeholder groups in defining quality of care within primary care mental health services. These indicators could provide a guide for primary care organisations embarking on quality improvement initiatives in mental health care when addressing national targets and standards relating to primary care set out in the National Service Framework for Mental Health for England. Although many of the indicators relate to parochial issues in UK service delivery, the methodology used in the development of the indicators could be applied in other settings to produce locally relevant indicators.

     

Proximal femoral focal deficiency: radiologic analysis of 49 cases

Proximal femoral focal deficiency, an uncommon congenital anomaly, necessitates early radiologic classification for surgical planning and treatment. Objective radiographic criteria, including femoral length index, acetabular depth index, acetabular angle index, and shape of the proximal femur were determined in 49 patients before cartilaginous ossification of the femoral capital epiphysis; final classification was based on follow-up radiographs or findings at arthrography or surgery. These parameters were analyzed to determine the accuracy and contributions of each in classification. Correct classification into one of three groups was possible in 86% of cases with use of three of the parameters: femoral length index, acetabular depth index, and shape of the proximal femur. The acetabular angle was found to contribute insignificantly to classification. Magnetic resonance imaging, used in only one case, depicted the nonossified cartilaginous femoral capital epiphysis, thus obviating the need for invasive diagnostic procedures and facilitating early classification.     

Inguinal herniorrhaphy in the continuous ambulatory peritoneal dialysis patient.

Inguinal hernia repair in the patient on continuous ambulatory peritoneal dialysis (CAPD) is complicated in theory by an increased potential for recurrence. In addition to the constant increased intraabdominal pressure, chronic renal failure has been shown to impair tissue healing. Controversy exists regarding the waiting period before resuming CAPD postoperatively. A retrospective review of all CAPD patients undergoing inguinal herniorrhaphy was performed. The patient's age, type of repair, duration of renal failure preoperatively, length of time on CAPD postoperatively, and date of resumption of CAPD were recorded. An inpatient and outpatient chart review was performed on all patients. Telephone follow-up was performed on surviving patients. From April 1981 to June 1989, 30 patients underwent 36 inguinal herniorrhaphies while on CAPD. One immediate postoperative death occurred due to underlying cardiac disease. The mean follow-up for surviving patients was 34 months (range, 16 to 91) and for those deceased was 25 months (range, 1 to 60). No recurrent hernias were identified either by extensive inpatient and outpatient chart review, or by direct patient telephone contact in all surviving patients. We conclude that inguinal herniorrhaphy can be safely performed in CAPD patients. Peritoneal dialysis can be initiated immediately after repair in this high-risk group of patients. There is a low risk of recurrence; however, long-term patient survival is not expected due to concurrent underlying medical problems.
