Probiotics for preventing and treating infant regurgitation: A systematic review and meta-analysis

Infant regurgitation is common during infancy and can cause substantial parental distress. Regurgitation can lead to parental perception that their infant is in pain. Parents often present in general practitioner surgeries, community baby clinics and accident and emergency departments which can lead to financial burden on parents and the health care system. Probiotics are increasingly reported to have therapeutic effects for preventing and treating infant regurgitation. The objective of this systematic review and meta-analysis was to evaluate the efficacy of probiotic supplementation for the prevention and treatment of infant regurgitation. Literature searches were conducted using MEDLINE, CINAHL, and the Cochrane Central Register of Controlled trials. Only randomised controlled trials (RCTs) were included. A meta-analysis was performed using the Cochrane Collaboration methodology where possible. Six RCTs examined the prevention or treatment with probiotics on infant regurgitation. A meta-analysis of three studies showed a statistically significant reduction in regurgitation episodes for the probiotic group compared to the placebo group (mean difference [MD]: ?1.79 episodes/day: 95% confidence interval [CI]: ?3.30 to ?0.27, N = 560), but there was high heterogeneity (96%). Meta-analysis of two studies found a statistically significant increased number of stools per day in the probiotic group compared to the placebo group at 1 month of age (MD: 1.36, 95% CI: 0.99 to 1.73, N = 488), with moderate heterogeneity (69%). Meta-analysis of two studies showed no statistical difference in body weight between the two groups (MD: ?91.88 g, 95% CI: 258.40–74.63: I² = 23%, N = 112) with minimal heterogeneity 23%. Probiotic therapy appears promising for infant regurgitation with some evidence of benefit, but most studies are small and there was relatively high heterogeneity. The use of probiotics could potentially be a noninvasive, safe, cost effective, and preventative positive health strategy for both women and their babies. Further robust, well controlled RCTs examining the effect of probiotics for infant regurgitation are warranted.     

In vitro evidence that subcutaneous administration of glatiramer acetate induces hyporesponsive T cells in patients with multiple sclerosis

Glatiramer acetate (GA; Copaxone) is a random sequence polypeptide used in the treatment of relapsing remitting multiple sclerosis (RR MS). We have recently demonstrated that prior to treatment, GA induces proliferation of resting T cells and is not cross-reactive with myelin antigens. Daily GA injections induce a significant loss of this GA responsiveness, which is associated with the induction of highly cross-reactive Th2-type T cells potentially capable of suppressing inflammatory responses. The mechanism of action by which GA induces T cell nonresponsiveness leading to T cell receptor degeneracy in patients with RR MS is unknown. Here, we examined the effects of daily GA administration on the induction of T cell hyporesponsiveness. The frequency of GA-reactive T cells in peripheral blood of seven patients with RR MS was measured by limiting dilution analysis prior to and during 6 months of treatment. In addition, a model in which GA-reactive T cells were stimulated in vitro was developed to better characterize the selection of T cell populations over time. In vivo treatment with GA induced a decrease in GA-reactive T cell frequencies and hyporesponsiveness of CD4(+) T cell reactivity to GA in vitro that was only partially reversed by the addition of IL-2. These data suggest that T cell peripheral tolerance to GA was achieved in vivo during treatment. Thus, our in vitro data suggest that the underlying changes in GA-reactive CD4(+) T cell reactivity could be explained by the induction of T cell anergy and clonal elimination.     

Response to oral β-carotene supplementation in patients with cystic fibrosis: a 16-month follow-up study

The aim of this study was to determine the efficacy of long-term oral β -carotene supplementation for correcting impaired β -carotene status in cystic fibrosis patients. Thirty-five patients (2.3-30.5 years of age) with coefficients of fat absorption of 46-96% (median 88%) received β -carotene 0.5 mg/kg daily and were followed over a 16-month treatment period. Baseline plasma β -carotene concentrations in patients (meanSD, 0.090.06 μ mol/1) were significantly lower than those of age-matched controls (0.860.56 μ mol/1) ( p < 0.0001). Concentrations increased rapidly and reached a plateau at or before 3 weeks that was maintained throughout the study period. Values obtained at 3 weeks (0.890.64 μ mol/1) were significantly higher ( p < 0.0001) than those at baseline and did not differ from controls. Plasma retinol and α -tocopherol concentrations increased during the observation period, but remained within normal ranges. Plasma retinyl palmitate, which was below the detection limit in all but one patient at baseline, did not increase. Thus oral β -carotene supplementation is effective and normalizes β -carotene status of cystic fibrosis patients without evidence of significant side effects. β -Carotene, cystic fibrosis, LDL-cholesterol, oral supplementation, retinol, α-tocopherol     

Malignant granular cell tumour of the sciatic nerve

A case of malignant granular cell tumour of the sciatic nerve is presented. Computed tomography demonstrated iso-density with muscle and minimal enhancement. Magnetic resonance demonstrated T1 isointensity with muscle with marked enhancement, and isointensity with fat on proton and T2 images. Pathological evidence is presented for its probable Schwann cell histogenesis.     

Clinical incidence of lymphoedema in breast cancer patients in Jönköping County, Sweden

The clinical incidence of lymphoedema of the arm in breast cancer patients was studied before and after general mammography screening in the country of jönköping, Sweden. There was a significant decrease of incidence of lymphoedema from 15% in 1983 to 8% in 1988. Clinical and pathological therapy data have been analysed in relation to lymphoedema. Significant factors contributing to lymphoedema were the number of lymph nodes examined and the number of pathologically positive lymph nodes. A higher proportion of patients receiving post-operative radiotherapy to the axilla developed lymphoedema, compared with those with surgery alone.
A comparison between the two groups is impossible due to the fact that post-operative radiotherapy was prescribed only to patients with pathologically positive lymph nodes.     

Docetaxel and carboplatin as second-line chemotherapy for metastatic non-small cell lung cancer

The aim of this pilot study was to evaluate the activity and toxicity of docetaxel plus carboplatin as second-line treatment in patients with metastatic non-small cell lung cancer (NSCLC). Patients received docetaxel 75 mg/m(2) followed by carboplatin AUC 5 on day 1 every 3 weeks in an out-patient setting. Twenty-six patients were enrolled; 23 patients were diagnosed stage IV disease and three patients had a IIIB disease with malignant pleural effusion. The median interval from first to second-line treatment was 3.5 months (range 1-13). Patients received a total of 101 cycles with a median number of four cycles per patient (range 1-6). Five patients achieved a partial remission (19.23%; 95% confidence interval (CI) 6.55-39.35%), 11 had stable disease (42.31%) and ten progressed (38.46%) after initiation of second-line therapy. Median survival was 243 days (95% CI 182-336 days), the median progression-free survival was 118 days (95% CI 89-170 days), and the 1-year survival rate was 25.98% (95% CI 6.33-45.63%). Moderate haematological and mild nonhaematological toxicities were observed. No treatment-related death occurred. In conclusion, docetaxel plus carboplatin as second-line regimen has a reasonable activity with good tolerance and encouraging survival data.     

Observing decision‐making in the general practice consultation: who makes which decisions?

OBJECTIVE: To investigate opportunities for, and types of decision making in the general practice (primary care) consultation, and examine differences in skills of those doctors who are successful at meeting their patients' preferences and those who are less successful. DESIGN: Observation study of doctor-patient consultations in general practice. PARTICIPANTS: Patients attending for routine appointments in 12 general practice surgeries across Oxfordshire. METHODS: A total of 212 doctor-patient consultations were video-recorded. The patients involved completed a questionnaire to elicit their perceptions of how decisions were made. The video-taped recordings were coded with a new instrument, the Evidence Based Patient Choice Instrument (EBPCI), to classify the number and type of decision-making opportunities arising during each consultation. A total of 149 recordings were coded using the Oxbridge Rating Scale to assess the doctors' consultation styles. RESULTS: There was a range of decision-making opportunities in addition to those involving medical treatment. With the exception of 'fitness for work', decisions were generally 'doctor led'. There was only moderate agreement between patient perceptions of their level of involvement in decision making and the objective ratings using the EBPCI. There was wide variation in the ability of doctors to meet their patients' preferences for involvement. CONCLUSIONS: There are many decisions made in primary care consultations, in addition to those about medical treatments, in which patients could be involved to a greater extent than they currently are. Some doctors are significantly better than others at meeting different patients' preferences for their decision-making role. Patients' perceptions of shared decision making appears to be influenced by the doctors' general consultation skills.     

Elevated Serum Alpha Fetoprotein and Normal Liquor Alpha Fetoprotein Values in Association with an Abdominal Pregnancy

Summary: A case report is described in which abdominal pregnancy was misdiagnosed by ultrasound scanning as a pregnancy within a horn of a bicornuate uterus. Two serum alpha fetoprotein (SAFP) results were greatly elevated and an amniocentesis was performed, the liquor alpha fetoprotein (LAFP) and karyotype were normal. Elective Caesarean section was performed at 38 weeks for a persistent transverse lie and an abdominal pregnancy was found. The outcome was excellent for both the mother and child.
This is the first reported case of amniocentesis and measurement of LAFP in an abdominal pregnancy and confirms abdominal pregnancy as a rare cause of an elevated SAFP.     

Screening for a raised rectal temperature in Africa

The main purpose of this study was to compare rectal and axillary temperature measurements in African children. Altogether 573 sick children were seen in an outpatient setting in rural West Africa. Rectal and axillary temperatures were measured and the parent or guardian was asked if they thought that the child had a raised body temperature. Normal ranges were defined from an age matched population of 203 healthy children. A raised axillary temperature predicted a raised rectal temperature with a sensitivity of 98% and a specificity of 88%. The parents' impression that their child had a fever was a less sensitive (89%) and less specific (59%) indicator of raised rectal temperature. A raised axillary temperature is a good screening test for a raised rectal temperature in African children.
