ABSTRACT BACKGROUND: Reduced antioxidant defenses may reflect a poor protective response against oxidative stress and this may be implicated in progression of gestational diabetes mellitus (GDM). Oxidative stress induced by hyperglycemia plays a major role in micro and macrovascular complications, which imply endothelial dysfunction. OBJECTIVE: Our aim in this study was to investigate the association between GDM and oxidative stress markers measured in plasma, with regard to revealing changes to total antioxidant capacity (TAC) and total oxidant status (TOS) among mothers showing impairments in oral glucose tolerance tests (OGTTs). DESIGN AND SETTING: Prospective study at a university hospital in Turkey. METHODS: The study group consisted of 50 mothers with GDM, and 59 healthy mothers served as controls. Umbilical cord blood samples were taken from all mothers during delivery and breast milk samples on the fifth day after delivery. TAC, TOS, thiol and disulfide levels were measured. RESULTS: No statistically significant relationship between the blood and milk samples could be found. An analysis on correlations between TAC, TOS and certain parameters revealed that there were negative correlations between TOS and total thiol (r = -0.386; P < 0.001) and between TOS and disulfide (r = -0.388; P < 0.001) in milk in the control group. However, these findings were not observed in the study group. CONCLUSION: Our findings suggested that a compensatory mechanism of oxidative stress was expected to be present in gestational diabetes mellitus and that this might be ameliorated through good glycemic regulation and antioxidant supplementation.

RESUMO Objetivos: O objetivo deste estudo é comparar as curvas de aprendizagem dos especialistas em dois campos diferentes sem experiência prévia de dacriocistorrinostomia endonasal endoscópica e revelar as complicações com as taxas de sucesso cirúrgico. Métodos: Foram investigados retrospectivamente 90 pacientes que receberam dacriocistorrinostomia endonasal endoscópica consecutiva com preservação da mucosa realizada por um oftalmologista (Grupo 1, n=45) e realizada por um otorrinolaringologista (Grupo 2, n=45) entre outubro de 2017 e outubro de 2019. Foram incluídos no estudo pacientes admitidos com epífora e diagnosticados com obstrução primária do ducto nasolacrimal adquirido como resultado do teste de irrigação lacrimal, com idade superior a 18 anos e com, pelo menos, 6 meses de acompanhamento. Em todos os casos, patologias adicionais, como o desvio do septo, foram avaliadas por meio da realização de imagens maxilofaciais. Os prontuários dos pacientes foram avaliados quanto à duração da cirurgia, complicações e desempenho funcional. Resultados: A média de duração cirúrgica dos pacientes no Grupo-2 foi de 36,27 ± 11,61 minutos, enquanto no Grupo-1 foi de 43,62 ± 16,89 minutos, sendo a diferença estatisticamente significativa (p=0,018). O desempenho funcional no Grupo 1 foi de 84,4% (73,3% nos primeiros 15 casos, 93,3% nos últimos 15 casos) no Grupo 2, essa taxa foi de 88,9% (80% nos primeiros 15 casos, 93,3% nos últimos 15 casos) e a diferença não foi estatisticamente significativa (p=0,53). A intervenção do septo além da cirurgia endoscópica em ambos os grupos (p=0,03, p=0,005, respectivamente) e sangramento intenso durante a cirurgia (para ambos os grupos, p<0,0001) diminuiu significativamente o sucesso funcional. Conclusão: A dacriocistorrinostomia endonasal endoscópica, realizada após o treinamento necessário, pode ser realizada com alto sucesso e com baixas taxas de complicações por oftalmologistas que não estão familiarizados com a cirurgia endoscópica após adquirirem experiência com trinta casos.

ABSTRACT Purpose: To compare the learning curves of the specialists in two different fields without previous endoscopic endonasal dacryocystorhinostomy experience as well as to reveal the related complications with surgical success rates. Methods: We retrospectively investigated 90 patients who received consecutive endoscopic endonasal dacryocystorhinostomy with mucosa preservation by an ophthalmologist (Group 1, n=45) and an otorhinolaryngologist (Group 2, n=45) between October 2017 and October 2019. Patients who were admitted with epiphora complaints and diagnosed with primary acquired nasolacrimal duct obstruction through lacrimal irrigation test and aged >18 years with at least 6 months of follow-up were included in the study. In all cases, additional pathologies such as septum deviation were evaluated by performing maxillofacial imaging. Patients' medical records were evaluated in terms of surgery duration, complications, and functional achievements. Results: The mean surgical duration of the patients in Group-2 was 36.27 ± 11.61 min, while it was 43.62 ± 16.89 min in Group-1; the difference was statistically significant (p=0.018). Functional achievements in Group 1 was 84.4% (73.3% in the first set of 15 cases, 93.3% in the last set of 15 cases) in Group 2; this rate was 88.9% (80% in the first set of 15 cases, 93.3% in the last set of 15 cases), and the difference was not statistically significant (p=0.53). Septum intervention in addition to endoscopic surgery in both the groups (p=0.03, p=0.005, respectively) and intense bleeding during surgery (for both the groups, p<0.0001) significantly decreased the functional success. Conclusion: Endoscopic endonasal dacryocystorhinostomy, performed after the necessary training, can provide high success and low complication rates when even conducted by ophthalmologists who are unfamiliar with endoscopic surgery after an experience of 30 cases.

RESUMO O objetivo deste estudo é discutir um caso de ceratite tardia por Klebsiella oxytoca, após ceratoplastia lamelar anterior profunda, bem como seu tratamento. Uma paciente de 21 anos apresentou vermelhidão e efluxo no olho esquerdo 5 meses após cirurgia de ceratoplastia lamelar anterior profunda sem complicações. Ao exame, havia uma única sutura solta na região nasal superior e uma área de infiltração com defeito epitelial no enxerto e na junção com o leito receptor na área da sutura solta. Iniciou-se empiricamente um tratamento tópico com vancomicina e ceftazidima fortificada de hora em hora, porém com resposta insuficiente. Após o crescimento de K. oxytoca a partir de cultura de swab e sutura retirados da paciente, a vancomicina fortificada foi substituída por imipenem fortificado. Observou-se que a área de infiltração regrediu rapidamente e que o defeito epitelial foi fechado com o tratamento com imipenem fortificado. O imipenem fortificado pode ser considerado um tratamento alternativo, especialmente nos casos sem resposta ao tratamento e detecção de crescimento na cultura.

ABSTRACT The aim of this study was to discuss a case of late-onset Klebsiella oxytoca keratitis after deep anterior lamellar keratoplasty and its treatment. A 21-year-old female patient presented with redness and effluence in the left eye at 5 months after uncomplicated deep anterior lamellar keratoplasty surgery. In the examination, a single suture was loosened in the superior nasal region and there was an infiltration area and epithelial defect in the graft and recipient bed junction in the area of the loose suture. Topical fortified vancomycin and fortified ceftazidime treatment was started empirically hourly, but there was insufficient response. After K. Oxytoca growth in a swab and suture culture taken from the patient, fortified vancomycin was replaced with fortified imipenem. It was observed that the infiltration area rapidly regressed and the epithelial defect was closed after fortified imipenem treatment. Fortified imipenem may be considered as an alternative treatment, especially in cases in which there is no response to treatment and culture growth is detected.

PURPOSE: Self-mutilation, known as self-harming behaviour of an individual without the intention of suicide, is commonly observed in individuals with borderline personality disorder. The objective of this study is to compare copeptin levels that are known to be related to aggressive behaviour and blood lipid profiles in borderline patients with and without self-mutilation. METHODS: Twenty patients with self-mutilation [SM(+)] and 20 patients without self-mutilation [SM(−)] between the ages of 18 and 49, diagnosed with borderline personality disorder based on DSM-IV-TR(8) diagnostic criteria and attended to by Fırat University Psychiatry Polyclinic, participated in the study. Socio-demographic and clinical data form, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale (HAMA) and Barrat Impulsivity Scale (BIS) were applied to all participants. Copeptin levels and plasma lipid levels were studied in the blood samples taken from the participants. RESULTS: Mean copeptin level found in SM(+) group (37.54 ± 18.8 ng/mL) was statistically significantly higher than SM(−) group (18.53 ± 16.6 ng/mL) (p = 0.002). A negative correlation was found between mean copeptin and mean total cholesterol levels (r = −0.436; p = 0.005), and between copeptin and low-density lipoprotein cholesterol (LDL) levels (r = −0.403; p = 0.01) in both SM(+) and SM(−) patient groups. HAMA mean score for SM(+) group was found as 36.45 ± 13.2, and for SM(−) group, it was found as 35.7 ± 12.9. There was a statistically. significant difference between the depression points achieved by the two groups (p = 0.046). BIS total points average for SM(+) group was determined as 71 ± 9.71, whereas it was determined as 66.8 ± 7.92 in SM(−) group. There was no statistically significant difference between the groups based on anxiety points. Barrat planning, Barrat motor and Barrat attention points for SM(+) group were higher than the SM(−) group. However, the difference was not statistically significant (p > 0.05). CONCLUSION: Findings of the study demonstrated that as cholesterol and LDL levels decreased, copeptin levels increased, and that could be related to the self-mutilation behaviour.
