Three eyelid localized cutaneous anthrax cases

Anthrax is primarily seen in the developing countries, but it can be a worldwide medical concern due to bioterrorism threats. Palpebral anthrax is a rare form of cutaneous anthrax. Untreated cutaneous anthrax can be lethal. Patients with palpebral anthrax can develop complications including cicatrisation and ectropion. Thus, anthrax should be considered in differential diagnosis for patients presenting with preseptal cellulitis in high-risk regions. Herein, we report three anthrax cases (with different age) involving eyelids that were cured without any complications due to early diagnosis and treatment.     

Comparison of measurements obtained with hand files or the Canal Leader attached to electronic apex locators: an in vitro study

AIM: The aim of the present in-vitro study was to combine directly the Canal Leader handpiece (SET, Olching, Germany) with the electronic apex locators ROOT ZX (Morita, Kyoto, Japan) and JUSTY (Yoshida, Tokyo, Japan) to find out whether the working length values thus obtained were identical to those resulting from the combination of the same electronic devices with hand files. METHODOLOGY: A total of 50 natural extracted teeth with single canals and mature apices were used. A radiograph was used as a control and the distance from the radiographic apex to the tip of the file was measured and compared with the results of the electronic length determination. RESULTS: For both electronic devices the differences amongst the distribution of the measurements were not statistically significant under the specified conditions (P > 0.05), indicating that the measurements with hand files and with the Canal Leader were identical for the majority of the cases. CONCLUSIONS: Under the conditions of this study the working length of canals obtained with electronically assisted hand files were similar to those obtained with the electronically assisted mechanical handpiece Canal Leader.     

Mild gentamicin nephrotoxicity reduces the progression of chronic adriamycin nephrosis

SUMMARY: The effect of mild acute tubular injury on the progression of tubulointerstitial fibrosis was studied in pair-fed uninephrectomized male Wistar rats with established adriamycin nephrosis ( n = 34). Rats were stratified into three groups according to endogenous creatinine clearance (CrCl), proteinuria (Upr) and body weight (BW): (i) group 1 (Fe, n = 12) received a single intraperitoneal injection of ferric nitrilotriacetate (5 mg Fe/kg BW); (ii) group 2 (G, n = 10) three daily subcutaneous injections of gentamicin (60 mg/kg BW) and; (iii) group 3 (C, n = 12) saline injections. Serial CrCl (day 2, day 5, weeks 2, 4, 6 and 8) and renal histology (week 8) were examined following administration of nephrotoxin. CrCl was reduced on d2 (Fe: 0.78 ± 0.23 mL/min; mean ± SD) and day 5 (G: 0.91 ± 0.36 mL/min) as compared with C (1.22 ± 0.12 mL/min; P <0.05). There was no change in the serum creatinine and functional recovery occurred by d5 (Fe) and week 2 (G). Upr decreased transiently in G at week 2 (G: 482 ± 208 mg/day vs C: 716 ± 233; P = 0.05) despite similar food intake, baseline Upr and CrCl. At week 8, CrCl in Fe (0.84 ± 0.40 mL/min) was similar to C (0.84 ± 0.58 mL/min), whereas in G it remained stable (1.27 ± 0.39 mL/min; P <0.05). By morphometric analysis, mean relative interstitial volume (RIV) and glomerulosclerosis (GS) in Fe (RIV: 28.5 ± 13.4%; GS: 10.3 ± 12.3%) was no different to C (RIV: 24.5 ± 12.5%; GS: 20.9 ± 20.0%), whereas both parameters were reduced in G (RIV: 14.1 ± 8.1%; GS: 4.0 ± 4.8%; P <0.05). Mild gentamicin nephrotoxicity therefore reduced the progression of adriamycin nephrosis. the mechanism of this finding is unclear, but it may relate to altered glomerular and tubular cell handling of protein.     

延续性护理在心脏瓣膜置换术患者中的应用效果分析

目的 探讨延续性护理在心脏瓣膜置换术患者中的应用效果.方法 选取2017年1月—2019年1月在四川省德阳市人民医院接受心脏瓣膜置换术治疗的80例瓣膜性心脏病患者作为研究对象,随机分为观察组和对照组各40例.出院后对照组不进行主动护理,观察组采用延续性护理,对两组患者干预前后服药依从性、生活质量及心功能进行比较分析.结果 出院时两组服药依从性、生活质量及心功能比较差异无统计学意义(P>0.05),出院后6个月观察组服药依从性、生活质量及心功能均优于对照组,差异有统计学意义(P<0.05).结论 延续性护理应用于心脏瓣膜置换术出院患者中可提高患者服药依从性,提升患者生活质量及心功能恢复,值得临床借鉴推广.     

Erythromycin treatment for gastrointestinal dysmotility in preterm infants

To report our clinical experience on the use of oral erythromycin for the treatment of severe gastrointestinal dysmotility in preterm infants.

Methodology:

A case series study of seven preterm infants (six were very low birthweight) with severe intestinal dysmotility in a tertiary neonatal centre.

Results:

All responded favourably without adverse effects and tolerated full enteral feeding within 1–2 weeks of the commencement of the drug.

Conclusions:

As prolonged total parenteral nutrition carries significant risk of complications, this therapy could be considered in selected preterm infants who fail to establish enteral feeding after an extended period, and in whom an anatomically obstructive lesion of the gastrointestinal tract has been excluded. Meanwhile, we would caution against the widespread implementation of this therapeutic approach until formal evaluation by randomized controlled trials have established the exact role of erythromycin, or its analogues, in the treatment of intestinal dysmotility in preterm infants.     

Immunoglobulins in cerebrospinal fluid in central nervous system disorders

Immunoglobulins were estimated in the cerebrospinal fluid from 70 cases of nervous system diseases. Thirty childern with evidence of C.N.S. irritation without infection served as controls. The immunoglobulins were higher in cases with C.N. S infections. Within this group meningeal involvement (tubercular and pyogenic) resulted in a significant rise in IgG compared to viral encephalitis. The proportion of immunoglobulin in the CSF protein can be helpful in distinguishing TBM from PM.     

Infection of human T-cell leukemia virus type I and development of human T-cell leukemia lymphoma in patients with hematologic neoplasms: a possible linkage to blood transfusion

Among 354 adult patients with either hematological malignancy or aplastic anemia, eight were positive for anti-HTLV-I antibodies; six of eight had received multiple transfusions. There was an approximately 3.5-fold increase (P less than .001) of HTLV-I seropositivity in the patients with hematologic disease (8 of 354, 2.23%) compared to the healthy adults older than 20 years (34 of 5252, .65%). Two hematological patients, one with Hodgkin's disease and one with acute promyelocytic leukemia, were found to be positive for HTLV-I, and developed and died of adult T-cell leukemia/lymphoma (ATL) subsequently. Both were long-term survivors of the primary disease and had received multiple transfusions. The latent period from blood transfusion to onset of ATL was 6 months and 11 years, respectively. Immunocompromised patients, who were seropositive for HTLV-I, may be at increased risk for ATL compared to healthy carriers of HTLV-I, and the latent period may be shorter.
