Assessment of bioequivalence after subcutaneous and intramuscular administration of urinary gonadotrophins

The objective was to demonstrate bioequivalence between s.c. and i.m. administration of Humegon (FSH/LH ratio 1:1) and Normegon (FSH/LH ratio 3:1). In two randomized, single-centre, cross-over studies, 18 healthy volunteers on each formulation were assigned to one of the two administration sequences. Subjects were given single doses of one of the above gonadotrophins after endogenous gonadotrophin production had first been suppressed using high-dose oral contraceptive. Subsequently, rate (Cmax, tmax) and extent (AUC) of absorption of follicle stimulating hormone (FSH) and luteinizing hormone (LH) were determined for 14 days. For Cmax and AUC, analysis of variance (ANOVA) was performed on log-transformed data and for tmax ANOVA was performed on ranks. Intramuscular and s.c. injections of Humegon were bioequivalent with respect to the main pharmacokinetic parameters, being AUC and Cmax of FSH absorption. Intramuscular and s.c. injections of Normegon were bioequivalent with respect to the AUC of FSH and not bioequivalent with respect to the Cmax of FSH. For tmax of FSH as well as for most LH variables of both preparations, bioequivalence could not be proven due to the high intra- and interindividual variability and/or concentrations being close to the detection limit. Thus, the main pharmacokinetic FSH variables after i.m. and s.c. administration of Humegon and Normegon were bioequivalent.      

The gene for hereditary multiple exostoses does not map to the Langer-Giedion region (8q23-q24).

Hereditary multiple exostoses is a dominantly inherited skeletal disorder which alters enchondral bone during growth and is characterised by exostoses of the juxta-epiphyseal regions. Using polymorphic DNA probes, we have been able to exclude the disease gene from close proximity to the 8q24.1 region where a dominant syndrome with multiple exostoses, the trichorhinophalangeal syndrome type II (TRP II, Langer-Giedion syndrome, MIM 15025), has been previously localised (pairwise linkage Z = -8.96 at theta = 0 with probe L48 at locus D8S51). Multipoint linkage analysis using probes L48, L24, and L1 consistently excluded the HME gene from a large area of the distal long arm of chromosome 8, spanning the smallest region of overlap assigned to the TRP II gene. These studies support the clinical view that HME and TRP II are distinct entities.     

延边地区肺结核病人归口转诊模式的探讨

目的　分析延边地区建立肺结核归口转诊模式对肺结核病人的转诊到位率的影响,探讨提高转诊到位率的方法。方法 对全州8个县(市)医院、中医医院、中心卫生院、大型厂矿企事业单位职工医院的执法检查考核资料进行评价。结果 1.建立归口转诊模式前期转诊率为48.3%,转诊到位率为29.0%,后期转诊率为89.0%,转诊到位率为72.4%,有明显提高;2.前期年平均涂阳病人新登记率为13.36/10万,后期为17.86/10万,实施归口转诊模式前期与实施后期的指标有显著性差异(P<0.01)。结论 延边地区实施的肺结核病人归口转诊模式,对提高肺结核病的转诊到位率十分有效,应不断完善并深入推广。     

Utero-cutaneous fistula following cesarean section: A case report

Utero-cutaneous fistula is a rare pathology. It mostly occurs consecutively to surgical intervention such as Cesarean section. Blood discharge from the cesarean scar during menstruation is a quasi-pathognomonic feature. Imaging modalities, particularly with the injection of contrast material through the cutaneous fistulous opening, confirm the diagnosis. The management is mainly surgical.We report the case of a utero-cutaneous fistula in a 27-year-old lady, with systemic lupus erythematosus. She presented seven months after her third cesarean section with pain and blood discharge from the cutaneous scar during menstruation for four months. A pelvic CT scan with the injection of the contrast material through the cutaneous fistulous opening confirmed the diagnosis of utero-cutaneous fistula. Surgical management was successful.     

复治肺结核病人的成因分析

目的　探讨复治肺结核病人形成原因。方法　使用调查表的方法 ,对前来诊治的复治涂阳肺结核病人的首次诊疗 ,管理情况进行问卷调查。结果　综合医院仍然为大多数患者的首次诊疗单位 ,因此部分肺结核患者未能得到正确的诊断、治疗和化疗管理。导致 67.2 %病人“中断”或“间断”治疗 ;另外结核病健康教育宣传做得不够 ,60 .3 %的患者诊断前未接受过防痨宣教 ,3 4.5 %的患者接受初次化疗时仍未得到宣教。这些均在导致复治病人的产生中起了重要作用。结论　加大DOTS覆盖面 ,加强归口管理力度 ,做好防治结核病教育工作是防止复治肺结核病人产生的重要环节。     

Foot orthotics decrease pain but do not improve gait in rheumatoid arthritis patients

OBJECTIVES: Prescribing foot orthotics in rheumatoid arthritis patients with symptomatic forefoot involvement is a standard practice. However, limited research has been reported regarding gait and pain improvement with the use of foot orthotics. PATIENTS AND METHODS: Sixteen patients (13 F, 3 M; mean age: 52 +/- 12 years) with metatarsalgia due to rheumatoid arthritis were included in this prospective, randomized with crossover study, and received foot orthotics. At 1 month follow-up, space and time gait variables with and without foot orthotics were assessed by Bessou's locometer; pain was assessed by visual analogue scale (VAS). RESULTS: Pain levels significantly decreased (P = 0.008) by wearing foot orthotics. Despite a significant step length increase (P = 0.05) with orthotics, there was no significant improvement of stride length, cadence, or walking speed which was the main assessment criterion. CONCLUSIONS: Wearing foot orthotics improves pain, but not sufficiently to improve gait in rheumatoid arthritis patients with metatarsalgia. Foot orthotics improved comfort levels because of a decrease in pain, but was not sufficient to correct gait.     

Asthma in children: Management practices among paediatricians and family physicians

OBJECTIVE:

To ascertain the variation in asthma management practices among paediatricians and family physicians to determine how to improve care.

DESIGN:

Questionnaire study of paediatricians and family physicians that focused on the use of beta₂-agonists, inhaled corticosteroids, patient asthma education, quantitative measurements of airflow and diagnostic investigations for asthma. Case scenarios were used in the questionnaire.

RESULTS:

The response rate was 66% (415 of 632) among paediatricians and 42% (1156 of 2750) among family physicians. In general, both groups followed consensus guidelines. There were some differences in management practices among paediatricians and family physicians. Paediatricians were more likely to develop an action plan and less likely to use xanthines or inhaled anticholinergic agents. However, family physicians were more likely to use spirometry or home peak expiratory flow rates to make a diagnosis of asthma.

CONCLUSION:

Family physicians and paediatricians require a different focus on educational interventions to improve the care of children with asthma.     

Pulmonary cystic hydatid disease in Ireland

Background Hydatid disease is rare in Ireland and its incidence and prevalence are unknown. Most cases are diagnosed by a combination of clinical findings, morphological features on imaging and by serological testing. Aims We describe an Irish case of pulmonary hydatid disease detected at bronchoscopy by bronchoalveolar lavage, and discuss the diagnosis and treatment of the disorder.
