Fatty acid-binding protein-4 as a biomarker predicting acromegaly-associated diabetes mellitus

Background/aimThe known pathogenesis of diabetes mellitus (DM) in acromegaly is mainly based on growth hormone (GH) and insulin-like growth factor-1 (IGF-1) excess. Fatty acid-binding protein 4 (FABP-4), a novel adipokine, is found to induce insulin resistance and type 2 DM. We aimed to investigate the possible effect of FABP-4 on glucose metabolism in patients with acromegaly.Materials and methodsThis case-control study included 28 patients newly diagnosed with acromegaly and 57 healthy volunteers. The patients with acromegaly were classified according to their glycemic status as with DM, prediabetes, and normal glucose tolerance. Anthropometric measurements, laboratory test results, and FABP-4 levels of the subjects were evaluated.ResultsAlthough no difference was observed in FABP-4 levels between acromegaly and control groups, the FABP-4 level was higher in the patients with acromegaly having DM compared to the patients with acromegaly having prediabetes and NGT, and the control group (p = 0.004, p = 0.001, p = 0.004, respectively). Logistic regression analysis suggested that the FABP-4 is an independent predictor of DM in acromegaly (β = 7.382, OR = 38.96, 95% CI: 1.52-5.76, p = 0.018).Conclusion The FABP-4 may be a helpful predictor of acromegaly-associated DM.     

Congenital middle-ear deafness: CT study

Computed tomography (CT) was used to study 25 patients with congenital conductive hearing loss and normal external auditory canals. Deformities were subdivided according to ossicular, fenestral, and cholesteatomatous origin. Isolated ossicular deformities were found in 14 patients (five bilateral), cholesteatoma in eight, oval-window nondevelopment (with ossicular deformity) in one, and normal studies in two (congenital stapes fixation at the level of the annular ligament). Ossicular deformities may be subdivided into incudostapedial disconnections into incudostapedial disconnections (most common), malleoincudal fixations, and stapes fixations. Most are due to developmental anomaly of the first or second branchial arch. The stapes has a dual origin (second arch and otic capsule). A cholesteatoma is defined as congenital only if there is no history of otitis and the tympanic membrane is intact. In this series, six were in the middle ear proper, and two were within the attic beyond otoscopic view. Their CT appearance, with one exception, was essentially identical to that of acquired lesions.     

万古霉素与利奈唑胺治疗脓毒症对C反应蛋白和降钙素原的影响

目的 探讨万古霉素与利奈唑胺治疗脓毒症对C反应蛋白和降钙素原的影响。方法 选择2016年1月~2020年12月我院收治的268例脓毒症患者为研究对象,均采用万古霉素或利奈唑胺治疗,运用倾向性评分匹配法矫正组间混杂因素,通过重复测量方差分析法对用药前、用药3 d时的CRP和PCT水平变化情况。结果 268例患者中,120例行万古霉素治疗,148例行利奈唑胺治疗;在利奈唑胺组中,用药3 d时的CRP和PCT水平均低于用药前（P<0.05）;而在万古霉素组中,用药前后的CRP和PCT水平比较无差异（P>0.05）;同时,经倾向性评分匹配对混杂因素进行矫正后,两组患者的治疗有效率和生存率比较差异无统计学意义（P>0.05）。结论 临床上在治疗脓毒症患者时,使用利奈唑胺治疗后,能够使CRP和PCT水平降低,起效时间短,但是万古霉素和利奈唑胺在治疗结局方面无明显差异。

Hypnotherapy: A Useful Adjunctive Therapeutic Modality in Hansen's Disease

Hypnotherapy is a useful adjunctive psychotherapeutic procedure used in various conditions such as pain disorders, atopic dermatitis, and alopecia areata. However, it is less utilized in the field of dermatology. Only limited data exist on its role in the management of various skin diseases. There is dearth of literature on the role of hypnotherapy in Hansen''s disease (HD). We report two cases of HD, one with very resistant neuralgia and the other with recurrent erythema nodosum leprosum (ENL). Both the patients were assessed using hospital anxiety and depression scale, dermatology life quality index and the neuralgia was assessed using the visual analog scale. Three sessions of hypnotherapy were given to both the patients. There was dramatic improvement in the incidence of ENL and neuralgia and we could rapidly reduce the dose of drugs used for both conditions.     

A holiday break for adolescents provided by the Malcolm Sargent cancer fund for children

The paper describes a holiday for a group of adolescents with cancer (from the Young Oncology Unit at the Christie Hospital, Manchester, UK) at Malcolm Sargent House, Prestwick, Scotland. The aim was to provide an opportunity for young people with cancer to build and to develop therapeutic relationships away from the pressures of hospital, home and treatment. The nature and range of care given by the nurses and social worker who accompanied them is described and includes accounts of individual progress which are demonstrated by brief case studies.     

Pharmacokinetics of biliary excretion of N-nitrosodimethylamine in rats fed diets containing levels of protein

Albino Wistar rats (Rattus norvegius) fed semi-purified diets containing 3.5%, 8%, 27%, and 64% casein, respectively, as the protein source, were poisoned with an intraperitoneal dose of 20mg N-nitrosodimethylamine (NDMA)/kg, following cannulation of the bile duct, in vitro, under urethane anaesthesia. Bile exudates was collected at designated time intervals and analysed for unchanged NDMA using thin layer chromatography and gas liquid chromatography methods. Rats on 64% high protein diet (HPD) were the highest excretors of NDMA, followed by rats on the 3.5% kwashiorkorigenic diet (KWD), 8% low protein diet (LPD) and 27% normal protein diet (NDP) as the least excretors, in that order. The corresponding values for culmulative excretions of NDMA were 4.38%, 2.74%, 2.96% and 4.11%, and for elimination rate contents they were 54.05Kh⁻¹, 23.01Kh⁻¹, 23.76Kh⁻¹ and 48.88Kh⁻¹, while the respective elimination half-life values were 0.013h, 0.031h, 0.029h and 0.014h. The toxicological and pharmacological implication of the pharmacokinetic findings are discussed.     

Increased trinucleotide repeat instability with advanced maternal age

Nucleotide repeat instability is associated with an increasing number of cancers and neurological disorders. The mechanisms that govern repeat instability in these biological disorders are not well understood. To examine genetic aspects of repeat instability we have introduced an expanded CAG trinucleotide repeat into transgenic mice. We have detected intergenerational CAG repeat instability in transgenic mice only when the transgene was maternally transmitted. These intergenerational instabilities increased in frequency and magnitude as the transgenic mother aged. Furthermore, triplet repeat variations were detected in unfertilized oocytes and were comparable with those in the offspring. These data show that maternal repeat instability in the transgenic mice occurs after meiotic DNA replication and prior to oocyte fertilization. Thus, these findings demonstrate that advanced maternal age is an important factor for instability of nucleotide repeats in mammalian DNA.
