Resumen Objetivo: En el estudio actual nuestro objetivo fue investigar el efecto del dexpantenol en la cicatrización de heridas a nivel histopatológico en el tejido cavernoso. Métodos: se utilizaron 44 ratas Wistar albinas con un peso de 220-250 g. Las ratas se dividieron aleatoriamente en 4 grupos como grupo B, grupo S, grupo LD y grupo SD. En el grupo B, la incisión no se reparó y se dejó para la cicatrización secundaria. En el grupo S, la línea de incisión se reparó con sutura de poliglactina 5/0. En el grupo LD, se aplicaron 0.25 mg/kg de dexpentanol por vía subcutánea debajo de la región de la herida reparada una vez al día durante 14 días. En el grupo SD se aplicaron 500 mg de dexpentanol por vía intraperitoneal una vez al día durante 14 días. Resultados: No se observó fibrosis en 8 (80%) ratas del grupo SD. Las tasas de fibrosis fueron significativamente más bajas en el grupo SD en comparación con el grupo B, el grupo S y el grupo LD (todos p < 0.05). Conclusión: La administración sistémica de dexpantenol disminuyó significativamente la fibrosis en el modelo de fractura de pene en ratas.

Abstract Objectives: In the present study, we aimed to investigate the effect of dexpanthenol on wound healing at the histopathological level on cavernous tissue. Materials and methods: Forty-four Wistar albino rats weighing 220-250 g were used. The rats were randomly divided into four groups as Group B, Group S, Group LD, and Group SD. In Group B, the incision was not repaired and left to secondary healing. In Group S, the incision line was repaired with 5/0 polyglactin suture. In Group LD, 0.25 mg/kg dexpanthenol was applied subcutaneously below the repaired wound region once a day during 14 days. In Group SD, 500 mg dexpanthenol was applied intraperitoneally once a day during 14 days. Results: No fibrosis was observed in 8 (80%) rats in group SD. Fibrosis rates were significantly lower in Group SD compared to Group B, Group S, and Group LD (p = 0.013, p = 0.005, and p = 0.003, respectively). Conclusion: Systemic dexpanthenol administration significantly decreased fibrosis in penile fracture model on rats.

SUMMARY OBJECTIVE: The aim of this study was to analyze the results of microsurgical testicular sperm extraction (micro-TESE) and investigate the potential factors that may affect the successful sperm retrieval and timing of micro-TESE. METHODS: A total of 56 patients with nonobstructive azoospermia (NOA) who underwent micro-TESE procedure between January 2017 and December 2019 were retrospectively analyzed. The patient age, marriage duration, infertility duration, smoking, chronic illness, varicocele status, previous scrotal surgeries, and the presence of genetic disease were noted by an urologist for all patients. RESULTS: The mean age of patients was 33.28±4.4 (22–44) years. Our total sperm-retrieval rate was 55.4% (n:31). Sixteen (28.6%) pregnancies were achieved and 15 (26.8%) healthy live births could be managed. Only the marriage duration (p=0.016) and infertility duration (p=0.015) were detected to be the significant factors to manage successful sperm retrieval. Men with NOA younger than 35.2 years and having a female partner younger than 36.9 years seemed to have the best chance to have a living healthy baby. CONCLUSIONS: The fertility decreased by both male and female age and for men with NOA. The early visit to doctor seemed to have positive effect.

RESUMO A relação entre pancreatite aguda e a administração de glicocorticoides é incerta pois a maioria dos casos relatados foram diagnosticados com doenças vasculares sistêmicas, como lúpus eritematoso sistêmico, que pode causar pancreatite. Uma paciente de 22 anos com envolvimento ocular e lúpus eritematoso sistêmico recém-diagnosticado foi admitida em nosso hospital. Pulsoterapia intravenosa com metilprednisolona 1mg/kg foi administrada por 3 dias. Depois disso, a paciente foi tratada com prednisolona oral 40 mg/dia. Durante a pulsoterapia com corticoides, a paciente apresentava dor abdominal, dor nas costas, distensão, náusea e vômitos. O exame físico era compatível com quadro de abdome agudo e peritonite. Tomografia computadorizada do abdome revelou líquido difuso na região perihepática e periesplênica, com heterogeneidade ao redor do mesentério. Devido aos sintomas de abdome agudo, foi realizada laparotomia exploradora. Havia líquido livre difuso no abdome e alterações edematosas foram observadas em torno do pâncreas. A amilase e lipase do líquido intra-abdominal foram analisadas e consideradas elevadas. A dose pós-operatória de prednol foi reduzida com cuidado. No sexto dia de pós-operatório, o dreno foi retirado, e a paciente recebeu alta sem qualquer problema. Médicos devem lembrar que a pancreatite aguda também pode ser uma causa de diagnóstico diferencial para dor abdominal recém-desenvolvida em pacientes recebendo pulsoterapia com corticoides e com níveis normais de amilase e lipase séricas.

SUMMARY The relationship between acute pancreatitis and the administration of glucocorticoids is unclear because most reported cases have been diagnosed with systemic vascular diseases, such as systemic lupus erythematosus, which may be responsible for pancreatitis. A 22-year-old woman with eye involvement of a newly diagnosed systemic lupus erythematosus was admitted to our hospital. Pulse intravenous methylprednisolone therapy was given at 1mg/kg day for 3 days, and oral prednisolone at 40 mg/day thereafter. During pulse steroid therapy, she had abdominal pain, back pain, distention, nausea, and vomiting. Her physical examination was compatible with acute abdomen and peritonitis. Abdomen Computerized Tomography scan revealed diffuse liquid perihepatic and perisplenic area with heterogeneity around the mesentery. Due to the symptoms of acute abdomen, explorative laparotomy was performed. There was diffuse free fluid in the abdomen and edematous changes were observed around the pancreas. Amylase and lipase from intraabdominal fluid were studied and found to be high. The postoperative prednol dose was reduced carefully. On the sixth postoperative day, the drain was removed, and the patient was discharged without any problem. Physicians should keep in mind that acute pancreatitis may also be a cause of differential diagnosis of newly developed abdominal pain in patients receiving pulse steroid therapy with a normal level of serum amylase and lipase.

Resumo Introdução O primeiro e um dos mais importantes passos na cirurgia plástica facial é a análise pré-operatória facial precisa e o registro de dados que podem ajudar o cirurgião a verificar os resultados de suas técnicas, promovendo seu desenvolvimento profissional. Objetivo Avaliar os resultados estéticos da rinosseptoplastia externa relevantes para a harmonia étnica facial e investigar a associação da cicatriz de incisão columelar com o tipo de pele e o tipo de incisão columelar em uma população turca. Método No total, 28 pacientes adultos consecutivos com média de idade de 32,14 ± 10,66 anos (intervalo: 18-61 anos) foram incluídos no estudo. Os desfechos primários foram as análises faciais fotogramétricas pré-operatórias e pós-operatórias dos pacientes, incluindo a medida do ângulo nasofrontal, ângulo nasolabial e razões da projeção nasal (Gode), avaliados de acordo com os dados derivados do programa Rhinobase. Os resultados foram comparados às proporções faciais da população turca. Os escores de cicatriz de incisão columelar relacionados com a classificação de Fitzpatrick do tipo de pele dos pacientes e os tipos de incisão columelar usados para a abordagem externa foram os desfechos secundários do estudo. Resultados Os ângulos nasofrontais pré- e pós-operatórios médios foram 148,04 ± 8,18° e 144,50 ± 7,15°, respectivamente, enquanto os ângulos nasolabiais pré- e pós-operatórios médios foram 87,59 ± 14,01° e 98,50 ± 9,71°, respectivamente. As razões médias da projeção nasal pré- e pós-operatória foram de 0,56 ± 0,05 e 0,60 ± 0,06, respectivamente. As diferenças entre as medidas pré- e pós-operatórias foram todas significativamente diferentes e estavam de acordo com a harmonia nasal turca. A incisão columelar em "V" invertido foi utilizada em 15 (53,6%) pacientes e a incisão em "V" foi utilizada em 13 (46,4%) pacientes. Pele Fitzpatrick tipo 4 foi observada em 46,42% dos pacientes, Fitzpatrick tipo 3 em 46,42% e Fitzpatrick tipo 2 em 7,14% dos pacientes. Não foi observada diferença significativa entre os escores de cicatriz columelar de acordo com o tipo de pele e o tipo de incisão columelar utilizados na rinosseptoplastia externa. Conclusões Este estudo demonstrou que os desfechos para ângulo nasofrontal, ângulo nasolabial e razões de projeção nasal analisados pelo programa Rhinobase em pacientes submetidos à rinosseptoplastia externa foram semelhantes aos valores de referência para a população turca.

Abstract Introduction The first and one of the most important steps in facial plastic surgery is accurate preoperative facial analysis and recording of data that may help the surgeon to check the outcomes of his/her techniques, promoting a surgeon's professional development. Objective To evaluate the esthetic outcomes of external septorhinoplasty relevant to ethnic facial harmony and to investigate the relationship of the columellar incision scar with the type of skin and columellar incision type in a Turkish population. Methods In total, 28 consecutive adult male patients with a mean age of 32.14 ± 10.66 years (range: 18-61 years) were included the study. Primary outcomes were preoperative and postoperative photogrammetric facial analyses of the patients including measurement of nasofrontal angle, nasolabial angle and nasal projection ratios (Gode) assessed according to the data derived from the Rhinobase program. Results were compared to facial proportions of the Turkish population. Columellar incision scar scores related to the Fitzpatrick skin type classification of the patients and columellar incision types used for the external approach were secondary outcomes of the study. Results Mean preoperative and postoperative nasofrontal angles were 148.04° ± 8.18° and 144.50° ± 7.15°, respectively, while mean preoperative and postoperative nasolabial angles were 87.59° ± 14.01° and 98.50° ± 9.71°, respectively. Mean preoperative and postoperative nasal tip projection ratios were 0.56 ± 0.05 and 0.60 ± 0.06, respectively. The differences between pre- and postoperative measurements were all significantly different and were in accordance with Turkish nasal harmony. Columellar inverted "V" incisions were performed in 15 (53.6%) patients while "V" incisions were used in 13 (46.4%) patients. Fitzpatrick skin Type 4 was seen in 46.42% of the patients, Fitzpatrick Type 3 in 46.42% and Fitzpatrick Type 2 in 7.14% of the patients. No significant difference was seen between columellar scar scores according to skin type and columellar incision type used for external septorhinoplasty. Conclusions This study demonstrated that outcomes for nasofrontal angle, nasolabial angle and nasal tip projection ratios analyzed using the Rhinobase program in patients who underwent external septorhinoplasty were similar to reference values for the Turkish population.

Resumo Introdução As células de Onodi são as células etmoidais mais posteriores, que se prolongam superolateralmente ao seio esfenoidal. Essas células também se encontram em íntima relação com o seio esfenoidal, o nervo óptico e a artéria carótida. Para análise de variações anatômicas antes da implantação de qualquer modalidade terapêutica relacionada ao seio esfenoidal, a avaliação radiológica é obrigatória, Objetivo Nosso objetivo foi avaliar o papel das células de Onodi na frequência de esfenoidite. Método Em nosso estudo, foi feita uma análise retrospectiva em 618 pacientes adultos que se submeteram à tomografia computadorizada de alta resolução entre janeiro de 2013 e janeiro de 2015. Avaliamos a prevalência de células de Onodi e de esfenoidite. Investigamos se a presença de células de Onodi leva a um aumento na prevalência de esfenoidite. Resultados A positividade para células de Onodi foi observada em 326 de 618 pacientes e sua prevalência foi de 52,7%. No grupo de estudo, 60,3% (n = 73) eram CO-positivas: ipsilateral (n = 21) ou bilateralmente (n = 52); e 39,7% (n = 48) eram CO-negativas (n = 35) ou apenas contralateralmente CO-positivas (n = 13). No grupo de controle, 48,3% (n = 240) eram CO-positivas; e 51,7% (n = 257) eram CO-negativas. Observamos que a coexistência de CO ipsilateralmente aumentava em 1,5 vez a associação com esfenoidite e esse achado foi estatisticamente significante (p < 0,05). Conclusão A prevalência de esfenoidite parece ser maior em pacientes com células de Onodi, mas não é possível afirmar que elas são isoladamente o fator causador dessa doença. Novos estudos precisam ser feitos para uma investigação dos fatores contributivos relacionados à esfenoidite.

Abstract Introduction Onodi cells are the most posterior ethmoid air cells and extend superolateral to the sphenoid sinus. These cells are also intimately related with the sphenoid sinus, optic nerve, and carotid artery. Radiologic evaluation is mandatory to assess for anatomic variations before any treatment modalities related to the sphenoid sinus. Objective To evaluate the effect of Onodi cells on the frequency of sphenoiditis. Methods A retrospective analysis was performed in 618 adult patients who underwent high-resolution computed tomography between January 2013 and January 2015. The prevalence of Onodi cells and sphenoiditis was evaluated. Whether the presence of Onodi cells leads to an increase in the prevalence of sphenoiditis was investigated. Results Onodi cell positivity was observed in 326 of 618 patients and its prevalence was found to be 52.7%. In the study group, 60.3% (n = 73) were ipsilaterally (n = 21) or bilaterally (n = 52) Onodi-positive, whereas 39.7% (n = 48) were Onodi-negative (n = 35) or only contralaterally Onodi-positive (n = 13). Of the control group, 48.3% (n = 240) were Onodi-positive and 51.7% (n = 257) were Onodi negative. The co-existence of Onodi cells ipsilaterally was observed to increase the identification of sphenoiditis 1.5-fold, and this finding was statistically significant (p < 0.05). Conclusion The prevalence of sphenoiditis appears to be higher in patients with Onodi cells. However, it is not possible to state that Onodi cells are the single factor that causes this disease. Further studies are needed to investigate contributing factors related to sphenoiditis.

RESUMO Introdução A espondilite anquilosante (EA) é uma doença reumática inflamatória crônica caracterizada pela inflamação da pelve e da coluna vertebral, que resulta em uma restrição na mobilidade da coluna vertebral. Em decorrência da postura alterada e da dor inflamatória noturna, os distúrbios do sono são passíveis de ocorrer em pacientes com EA. Objetivo Determinar as diferenças entre os pacientes com EA e controles saudáveis na qualidade do sono, bem como avaliar a relação entre a qualidade do sono e a atividade da doença. Método Para avaliar a qualidade do sono, 55 pacientes com EA (40 homens, 15 mulheres, idade média 43 ± 1 anos) que preencheram os critérios modificados de Nova York e 55 controles comparáveis (40 homens, 15 mulheres, idade média 42 ± 9 anos) preencheram o questionário Índice de Qualidade do Sono de Pittsburgh (PSQI). A atividade da doença foi avaliada pelo Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Resultados A espondilite anquilosante se correlacionou significativamente com a qualidade de sono prejudicada de acordo com os escores totais do PSQI (p = 0,001). Foram encontradas diferenças significativas entre os pacientes com EA e controles saudáveis nos domínios do PSQI, incluindo "qualidade subjetiva do sono" (p = 0,010), "duração do sono" (p = 0,011), "eficiência do sono habitual" (p = 0,034), "distúrbios do sono" (p = 0,003) e "disfunção diurna" (p = 0,009), mas não na "latência do sono" e no "uso de medicação para dormir". Houve uma correlação positiva entre as pontuações do BASDAI e do PSQI (r = 0,612, p = 0,001). Conclusão Verificou-se que os distúrbios do sono foram significativamente maiores em pacientes com EA em comparação com os controles. Os pacientes com doença ativa apresentaram pior qualidade de sono. Além disso, a atividade da doença esteve correlacionada com a pontuação da maior parte das subescalas do PSQI. A investigação da qualidade do sono deve ser uma ferramenta usada na avaliação de pacientes com EA.

ABSTRACT Introduction Ankylosing spondylitis (AS) is a chronic, inflammatory rheumatic disease characterized by the inflammation of the pelvis and spine that results in a restriction in the mobility of the spine. Due to the altered posture and nocturnal inflammatory pain, sleep disturbances are likely to occur in patients with AS. Objective This cross-sectional study aimed at determining the differences between the patients with AS and healthy controls in sleep quality, as well as assessing the relationship between the sleep quality and disease activity. Method In order to assess sleep quality, fifty-five patients with AS (40 men, 15 women; mean age, 43 ± 1 yrs) who fulfilled the modified New York criteria and fifty-five comparable controls (40 men, 15 women; mean age, 42 ± 9 yrs) completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The disease activity was assessed by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Results Ankylosing spondylitis was associated with a significantly impaired sleep quality according to the total PSQI scores (p = 0.001). Significant differences were found between the patients with AS and healthy controls in PSQI domains, including "subjective sleep quality" (p = 0. 010), "sleep duration" (p = 0. 011), "habitual sleep efficiency" (p = 0. 034), "sleep disturbances" (p = 0. 003) and "daytime dysfunction" (p = 0. 009) but not in "sleep latency", "use of sleep medication". There was a significant positive correlation between the BASDAI and PSQI scores (r = 0.612, p = 0.001). Conclusion In the current study, we found that the sleep disturbances were significantly higher in patients with AS in comparison to controls. Patients with active disease had worse sleep quality. In addition, disease activity was correlated with the scores of most of the PSQI subscales. Sleep quality assessment should be a tool for evaluating patients with AS.

Background: Hydatid Cyst is an infectious disease observed in many parts of the world, more often in endemic parts. While it can show symptoms related to the organ where it is localized, it can be also diagnosed incidentally. Aim: To report the experience in surgical treatment of hydatid cysts. Material and Methods: Retrospective review of 62 patients aged 17 to 75 years old (45 females), operated for hydatid cysts between 2002 and 2006. Results: The most common presenting complaint was right upper quadrant abdominal pain. The cyst was primary in 56 patients (90%) and a relapse in six (10%). Liver cysts were located in the right lobe in 41cases (66%) and left lobe in 11 (18%). Nine patients (15%) had bilateral lobe involvement. One patient (2%) had primary spleen hydatid cyst. Conservative surgery was used in all cases. A biliary fistula was found in 6 cases (10%) during the operation. In two patients, cysts were found in the choledochus and a choledochotomy was performed. Five patients had extrahepatic organ involvement of lung, omentum, colon meso and right ovary. Conclusions: To reduce the rate of relapse, operation technique must be carried out properly and carefully. Primary prophylaxis should be the first line of treatment of hydatid diseases.

Introducción: La Hidatidosis quística es una enfermedad infecciosa que se observa en muchas partes del mundo, más aún en zonas endémicas. En la mayoría, los síntomas son propios del órgano que afectan, pero a veces puede descubrirse de forma incidental. Objetivos: Describir e informar nuestra experiencia en el manejo quirúrgico de la hidatidosis quística. Material y Método: Quistes hidatídicos operados durante los últimos 7 años analizados de forma retrospectiva. Resultados y Discusión: Hubo 62 casos en nuestra serie, razón mujer hombre 45/17 y edad promedio de 41,6 años. Presentación más frecuente fue el dolor en cuadrante superior derecho. Cincuenta y seis (90,3%) casos fueron primarios y 6 (9,7%) recidivas. Compromiso de lóbulo hepático derecho en 41 casos (66%), izquierdo en 11 (17,7%) y bilateral en 9 (14,5%). Un caso fue (1,8%) primario esplénico. Se realizó cirugía conservadora en todos los pacientes. Se encontraron fístulas biliares en 6 casos (9,8%). En estos últimos el tamaño de los quistes fue de 14 cm. En 2 casos se observó compromiso del colédoco por lo que se realizó coledocostomía. En 5 casos (8%), se observó compromiso extrahepático los cuales fueron pulmón, omento, mesocolon y ovario derecho. Considerando que los quistes hidatídicos se pueden encontrar en todos los órganos, se debe realizar estudio imagenológico toracoabdominal. Para disminuir la tasa de recidiva, la técnica quirúrgica debe ser realizada de manera adecuada y cuidadosa. Debe realizarse profilaxis primaria como principal factor del tratamiento.
