Is diabetes mellitus a prognostic factor for survival in patients with small cell lung cancer?

Background: Previous studies have pointed to many different prognostic factors for small cell lung cancer(SCLC) but diabetes mellitus (DM) has not been clearly or consistently identified as of prognostic value. The aimof this study was to investigate the prognostic significance of the characteristics of patients and clinical laboratorytests in SCLC. Specifically, we investigated that the impact of DM for survival in the patients receiving first-lineetoposide plus cisplatin (EP) chemotherapy. Methods: We retrospectively reviewed 161 patients with SCLC witha focus on DM and other potential prognostic variables were chosen for univariate and multivariate analyseswith respect to survival. Result: Among the sixteen variables of univariate analysis, five were identified to haveprognostic significance: performance status (PS) (p <0.001), stage (p=0.001), DM (p=0.005), serum albumin (p<0.001) and hemoglobin levels (p=0.03). Multivariate analysis showed PS, stage and serum albumin level tobe independent prognostic factors for survival (p=0.02, p=0.02 and p=0.009 respectively), but DM was not anindependnet factor. Conclusion: In conclusion, PS, stage and serum albumin level were identified as importantprognostic factors, while DM at the time of diagnosis of SCLC did not have prognostic importance for survival.

Purpose

To report the 12?month real life outcomes of ranibizumab treated diabetic macular edema (DME) patients.

The efficacy and safety of bimatoprost/timolol maleate,latanoprost/timolol maleate,and travoprost/timolol maleate fixed combinations on 24-h IOP

Purpose

To evaluate the effect of bimatoprost/timolol maleate fixed combination (BTFC), latanoprost/timolol maleate fixed combination (LTFC), and travoprost/timolol maleate fixed combination (TTFC) on 24-h intraocular pressure (IOP) in patients with open-angle glaucoma.

Methods

This prospective, observer-masked, randomized study included 50 patients with primary open-angle glaucoma. All patients were using hypotensive lipids and timolol maleate fixed combination treatment for ≥4 weeks and had an IOP ≤ 21 mmHg. Group 1 (n = 18) received BTFC, group 2 (n = 14) received LTFC, and group 3 (n = 18) received TTFC. All patients were hospitalized, and IOP was monitored for 24-h (10:00, 14:00, 18:00, 22:00, 02:00, and 06:00). Mean diurnal IOP variation measurements were taken between 06:00 and 18:00, and mean nocturnal IOP variation measurements were taken between 22:00 and 02:00. Mean IOP and IOP variation in the three groups were compared.

Results

Mean 24-h IOP did not differ significantly between the three groups (group 1: 14.6 ± 2.9 mmHg; group 2: 14.1 ± 3.7 mmHg and group 3: 15.8 ± 2.0 mmHg; P > 0.05). Mean diurnal IOP variation was 4.6 ± 2.3 mmHg in group 1, 5.8 ± 2.4 mmHg in group 2, and 4.3 ± 1.7 mmHg in group 3, and mean nocturnal IOP variation was 3.2 ± 2.8 mmHg in group 1, 2.9 ± 1.9 mmHg in group 2, and 3.0 ± 1.6 mmHg group 3. There were not any significant differences in diurnal or nocturnal IOP variation between the three groups (P < 0.05).

Conclusion

All three fixed combinations effectively controlled IOP for 24-h and had a similar effect on diurnal and nocturnal IOP variations.

     

HPCA confirmed as a genetic cause of DYT2‐like dystonia phenotype

Background: HPCA (hippocalcin) is one of the underlying genetic causes of autosomal‐recessively inherited forms of dystonia. Here, we describe two consanguineous Turkish DYT‐HPCA families carrying the novel HPCA mutations. Methods: After detailed clinical and neurological examination, whole‐exome sequencing was performed. Results: Whole‐exome sequencing analysis revealed two homozygous novel truncating mutations (p.W103* and p.P10PfsTer80) in the HPCA gene in two unrelated Turkish dystonia families presenting with complex dystonia. Conclusions: After identification of HPCA as a genetic cause of DYT‐HPCA‐like dystonia by Charlesworth et al, this is the second report in the scientific literature that describes dystonia families harboring HPCA mutations. Our findings confirm that HPCA leads to recessively inherited dystonia. © 2018 International Parkinson and Movement Disorder Society     

Laparoscopic excision of renal hydatid cyst in a preadolescent

The traditional method of treating hydatid disease by open surgery has, in recent years, been challenged and minimally invasive approaches, including percutaneous and laparoscopic management, have been gaining wide acceptance. We present a 13-year-old boy with the diagnosis of isolated right renal hydatid disease, and a total pericystectomy was performed laparoscopically. Total operative time was 4.5 h and estimated blood loss was 150 ml. The only complication was an early urinary leak which was successfully treated with internal stenting. We believe further experience will reduce the operative time and complications.     

Bacterial etiology of acute otitis media and clinical efficacy of amoxicillin-clavulanate versus azithromycin

BACKGROUNDS: Acute otitis media (AOM) is one of the most common acute bacterial infection in childhood and also the most frequent reason for outpatient antibiotic therapy. Little recent information about susceptibility patterns of AOM bacterial pathogens in Turkish children has been reported. OBJECTIVE: To determine the bacterial etiology of acute otitis media in children and to compare the efficiency of 3 days course of azithromycin with a 10 days course of amoxicillin-clavulanate. METHODS: This prospective, single blind, randomised comparative study was carried out in 180 children with AOM. Paracentesis was performed for middle ear fluid culture before the first dose antibiotic therapy. Children with acute otitis media were randomised to receive either low dose amoxicillin-clavulanate (45/6.4 mg/kg/day in two divided doses for 10 days) or low dose azithromycin (10mg/kg/day for 3 days). Clinical response was assessed on days 2-4, 11-13, 26-28. RESULTS: Bacterial pathogens were isolated from 108 (60%) of 180 children. Streptococcus pneumoniae was the most common isolated pathogen (39.7%), followed by Haemophilus influenzae (20.7%), Moraxella catarrhalis (15.5%), Staphylococcus aureus (13.8%), Group A beta-hemolytic streptococcus (5.1%), Escherichia coli (3.4%) and Enterococcus faecalis (1.7%). This study demonstrated low resistance rates compared to studies of different countries. Although clinical response rates were better in patients treated with amoxicillin-clavulanate, this was not statistically significant [86.6% (78 of 90)] versus [95.2% (80 of 84)]. Success rates of amoxicillin-clavulanate were high for both S. pneumoniae and H. influenzae. Difference between success rates was not statistically significant (P=0.144 and 0.352). CONCLUSIONS: Bacteria were isolated in 60% of AOM cases. The clinical efficiency of amoxicillin-clavulanate was found to be equal compared to azithromycin in children with acute otitis media.     

Mucopolysaccharidosis type I (Hurler syndrome): oral and radiographic findings and ultrastructural/chemical features of enamel and dentin

Mucopolysaccharidosis type I (Hurler syndrome, MPS I-H) is an autosomal recessive inborn error of metabolism due to deficient alpha-L-iduronidase enzyme activity and is characterized by accumulation of incompletely degraded glycosaminoglycans that generally lead to impairment of organ and body functions. This report presents oral, dental, and radiographic findings in a boy who presented with MPS I-H. Nine of the patient's primary teeth were extracted and investigated using scanning electron microscopy, x-ray diffraction analysis, and Fourier transform infrared spectroscopy. Compared with the teeth of otherwise healthy patients, MPS I-H-affected dentin was characterized by extremely narrow dentinal tubules, whose direction followed an irregular wave-like pattern. The enamel-dentin junction was defective, as evidenced by microgaps, and the enamel displayed irregular arrangement of prisms. The additional novel observation was made that the protein structure of enamel and dentin changed in MPS I-H-affected teeth. Also, an increase was observed in the relative mineral/matrix ratio of MPS I-H-affected dentin, indicating that its protein content had decreased in comparison with normal dentin.     

Effect of oxygenated intraocular irrigation solutions on the electroretinogram after vitrectomy

PURPOSE: To investigate the effect of oxygenated intraocular irrigating solutions on electroretinograms (ERGs) for postvitrectomy rabbits. METHODS: Eight groups of five rabbits each underwent pars plana vitrectomy on the right eye; the left eye of each rabbit served as control. The intraocular irrigating solutions were balanced salt solution (BSS), BSS-plus, BSS + oxygen (BSS + O2), BSS-plus + O2, and combinations of each with the addition of endoillumination (L). All animals were evaluated by single-flash scotopic electroretinography on the operated and nonoperated eyes before surgery and at 1 hour, 1 day, 1 week, and 1 month after surgery by an unmasked observer. The main outcome measures were dark-adapted b-wave amplitudes of operated eye/nonoperated eye ratios. The results for the different groups were compared by analysis of variance. RESULTS: Mean dark-adapted b-wave amplitudes of operated eye/nonoperated eye ratios +/- SD for BSS-plus and BSS-plus + O2 before surgery and 1 hour, 1 day, 1 week, and 1 month after surgery were 1.01 +/- 0.09, 0.50 +/- 0.11, 0.95 +/- 0.11, 0.97 +/- 0.11, and 0.99 +/- 0.08 and 0.98 +/- 0.08, 0.59 +/- 0.10, 0.92 +/- 0.06, 0.97 +/- 0.08, and 0.97 +/- 0.10, respectively. At both 1 hour and 1 day after surgery, rabbits treated with BSS-plus + O2 had an earlier b-wave return to baseline findings, but the differences were not statistically significant (P > 0.05). Mean dark-adapted b-wave amplitudes of operated eye/nonoperated eye ratios +/- SD for BSS and BSS + O2 before surgery and 1 hour, 1 day, 1 week, and 1 month after surgery were 1.02 +/- 0.10, 0.47 +/- 0.09, 0.77 +/- 0.07, 0.89 +/- 0.07, and 0.89 +/- 0.07 and 1.02 +/- 0.06, 0.62 +/- 0.16, 0.94 +/- 0.09, 0.97 +/- 0.08, and 0.96 +/- 0.06, respectively. One hour and 1 day after surgery, ERG readings for rabbits treated with BSS + O2 exhibited a statistically significantly earlier return of ERG voltage to baseline values compared with both BSS and BSS + L (P = 0.05 and P = 0.02, respectively). One day after surgery, rabbits treated with BSS alone had the lowest ERG ratios. One week and 1 month after surgery, for all solutions tested other than BSS, ERG values were within normal limits. CONCLUSION: The use of oxygenated solutions appears to affect ERG readings after pars plana vitrectomy. Further studies to evaluate the role of oxygenated solutions in different vitreoretinal surgical procedures are warranted.
