RESUMO
AIM: Methotrexate has demonstrated efficacy in treating ectopic pregnancies. This study explores factors influencing treatment success, focusing on laboratory and ultrasonographic findings, particularly the day 4 to day 1 ß-hCG level ratio. METHODS: Retrospective cohort study was conducted within patients diagnosed with tubal ectopic pregnancy. Patients' characteristics, ultrasound findings, laboratory data, and ß-hCG levels (days 1, 4, 7), and operation findings were reviewed. Women's characteristics were investigated who were treated with single dose of MTX (50 mg/m2). Patients who were performed surgery after MTX treatment were identified as MTX treatment failure. RESULTS: Among 439 women, 259 underwent surgery due to acute symptoms. Of those treated with MTX, 143 experienced treatment success, while 37 underwent surgery after MTX (MTX failure). Comparative analysis revealed significant differences in ß-hCG levels on admission (1128 and 4125 mIU/mL) and the day 4 to day 1 ß-hCG ratio (0.91 and 1.25). The overall MTX success rate was 79%, reaching 93% and 89% for ß-hCG levels <1000 mIU/mL and <2000 mIU/mL, respectively. Success dropped to 50% with levels exceeding 5000 mIU/mL. ROC analysis identified a crucial 2255 mIU/mL cut-off for ß-hCG (sensitivity 70.3% and specificity 68.5%) and a day 4 to day 1 ß-hCG ratio of 95.5% (sensitivity 84.7%, specificity 72.5%, positive predictive value 75.4%) for predicting MTX success. CONCLUSION: Establishing a ß-hCG cutoff can reduce hospital stay. The day 4 to day 1 ß-hCG ratio holds promise as a widely applicable predictor for MTX success or for determining MTX administration on day 4.

PURPOSE: Social media has become the new information acquisition platform for all content producers. In the current literature, there are no studies examining the content quality and the strengths and weaknesses of videos on Instagram that explain anterior cruciate ligament (ACL) injuries, which is the most discussed topic of sports surgery. The aim of this study was to evaluate the quality, strengths and weaknesses of information pertaining to ACL surgery that is disseminated on Instagram. METHOD: An Instagram search was conducted from 30 May 2023 to 30 January 2024. The search encompassed six languages (English, Spanish, German, French, Italian and Turkish) and was performed by six different observers. The investigation focused on eight subheadings derived from current literature on the ACL. These subheadings were addressed in Instagram videos, covering ACL biology or biomechanics, injury mechanism, injury prevention, injury evaluation, surgical technique, injury or surgery complications, injury rehabilitation process and return to sport or work. RESULT: The content was assessed of 127 videos from 127 Instagram accounts, spanning six different languages. Across the review of eight subheadings, the average number covered for the entire group was 3 (range, 0-8). Further analysis revealed that surgical technique was the most frequently mentioned subheading for the whole group (68.5%), followed by injury evaluation (54.3%). Prevention (10.2%) and complications (19.6%) were the least mentioned subheadings. The number of followers showed a correlation with video content quality. CONCLUSION: Although the video quality scores were found to be moderate, the content often focused on surgery and evaluation subheadings. The prevalence of incomplete information underscores the importance of developing strategies to ensure more comprehensive and accurate dissemination of medical knowledge. LEVEL OF EVIDENCE: Level V.

BACKGROUND: High self-renewal capacity and most permissive nature of umbilical cord blood (CB) results with successful transplant outcomes but low hematopoietic stem and progenitor cell (HSPC) counts limits wider use. In order to overcome this problem ex vivo expansion with small molecules such as Valproic acid (VPA) or Nicotinamide (NAM) have been shown to be effective. To the best of our knowledge, the combinatory effects of VPA and NAM on HSPC expansion has not been studied earlier. The aim of this study was to analyze ex vivo and in vivo efficacy of VPA and NAM either alone or in combination in terms of expansion and engraftment. METHODS: A total of 44 CB units were included in this study. To determine the ex vivo and in vivo efficacy, human CB CD34+ cells were expanded with VPA and/or NAM and colony forming unit (CFU) assay was performed on expanded HSPC. Xenotransplantation was performed simultaneously by intravenous injection of expanded HSPC to NOD-SCID gamma (NSG) mice (n = 22). Significance of the difference between the expansion groups or xenotransplantation models was analyzed using t-test, Mann-Whitney, ANOVA or Kruskal-Wallis tests as appropriate considering the normality of distributions and the number of groups analyzed. RESULTS: In vitro CD34+ HSPC expansion fold relative to cytokines-only was significantly higher with VPA compared to NAM [2.23 (1.07-5.59) vs 1.48 (1.00-4.40); p < 0.05]. Synergistic effect of VPA+NAM has achieved a maximum relative expansion fold at 21 days (D21) of incubation [2.95 (1.00-11.94)]. There was no significant difference between VPA and VPA+NAM D21 (p = 0.44). Fold number of colony-forming unit granulocyte-macrophage (CFU-GM) colonies relative to the cytokine-only group was in favor of NAM compared to VPA [1.87 (1.00-3.59) vs 1.00 (1.00-1.81); p < 0.01]. VPA+NAM D21 [1.62 (1.00-2.77)] was also superior against VPA (p < 0.05). There was no significant difference between NAM and VPA+NAM D21. Following human CB34+ CB transplantation (CBT) in the mouse model, fastest in vivo leukocyte recovery was observed with VPA+NAM expanded cells (6 ± 2 days) and the highest levels of human CD45 chimerism was detectable with VPA-expanded CBT (VPA: 5.42 % at day 28; NAM: 2.45 % at day 31; VPA+NAM 1.8 % at day 31). CONCLUSION: Our study results suggest using VPA alone, rather than in combination with NAM or NAM alone, to achieve better and faster expansion and engraftment of CB HSPC.
RESUMO
Multiple myeloma (MM) is a haematological malignancy primarily affecting the elderly, with a striking male predilection and ethnic disparities in incidence. Familial predisposition to MM has long been recognized, but the genetic underpinnings remain elusive. This study aimed to investigate germline variants in Turkish families with recurrent MM cases. A total of 37 MM-affected families, comprising 77 individuals, were included. Targeted next-generation sequencing analysis yielded no previously reported rare variants. Whole exome sequencing analysis in 11 families identified rare disease-causing variants in various genes, some previously linked to familial MM and others not previously associated. Notably, genes involved in ubiquitination, V(D)J recombination and the PI3K/AKT/mTOR pathway were among those identified. Furthermore, a specific variant in BNIP1 (rs28199) was found in 13 patients across nine families, indicating its potential significance in MM pathogenesis. While this study sheds light on genetic variations in familial MM in Turkey, its limitations include sample size and the absence of in vivo investigations. In conclusion, familial MM likely involves a polygenic inheritance pattern with rare, disease-causing variants in various genes, emphasizing the need for international collaborative efforts to unravel the intricate genetic basis of MM and develop targeted therapies.

BACKGROUND: Natural killer (NK) cells are known to have cytotoxic effects mediated through killer immunoglobulin-like receptors (KIRs) and their cognate ligands. Role of KIRs in myeloma is yet unresolved. PATIENTS AND METHODS: KIR genotypes and ligands of 204 newly diagnosed MM patients are compared with 424 healthy subjects. Statistical analysis included t-test, chi-square and binary logistic regression. RESULTS: KIR ligands were significantly more (C2C2: 27.5% vs 15.1%; OR 2.128; 95% CI, 1.417-3.196; P < .001) or less (C1C2: 40.2% vs 51.9%; OR 0.623; 95% CI, 0.444-0.874; P = .006) frequent among MM. Co-occurrence of genotype AA with C2C2 was also higher in frequency among MM (OR 2.509; 95% CI, 1.171-5.378; P = .015) likewise cAB1 with C1C2 was less frequent (OR 0.553; 95% CI, 0.333-0.919; P = .021). Genotypes AA with C1C1, cAB1 with C1C2 or C1C2 alone were associated with a delay (median age: 61 [48-73]; P = .044; 62 [31-81]; P = .030 or 59 [31-85]; P = .028), but AA with C2C2 with an earlier age of onset (48 [29-77]; P = .042). In multivariate analysis including R-ISS, light chain, KIR genotype/ligands; ligand C1C2 (P = .02) and genotype AA-C1C1 (P = .037) were independently associated with age of onset ≥60. CONCLUSION: C1C2 and C2C2 alone or in combination with KIR genotype (cAB1 and AA, respectively), is observed in less or higher frequency among MM cases and associated with delayed/earlier age of onset, respectively. Genotype AA-C1C1 although in similar frequency between patients and healthy subjects, is also associated with delay. To our knowledge, this is the first study demonstrating an association between KIR and MM onset age, independent from R-ISS or light chain type.

OBJECTIVES: The aim of this study was to evaluate the factors that influenced one-year and five-year mortality and to compare major and minor amputations in diabetic patients with comorbidities. PATIENTS AND METHODS: Between February 2008 and November 2014, a total of 201 type 2 diabetic foot patients (147 males, 54 females; median age: 65.99 years; range, 50 to 92 years) who underwent amputation were retrospectively analyzed. The patients were divided into two groups according to their initial amputation level: Group 1 (n=100), minor amputation group, which included the distal region of the ankle joint and Group 2 (n=101), major amputation group, which included trans-tibial amputation, trans-femoral amputation and hip disarticulation. Clinical data including patients' demographic features, re-amputation degree, length of hospitalization, hyperbaric oxygen therapy, comorbidities, blood parameters, and survival rates were recorded. RESULTS: The regression analysis of one-year mortality found that the presence of cerebrovascular disease increased death by 2.463 times (p=0.002). Minor amputation increased mortality by 2.284 (p=0.006), and each unit increase in patient age increased mortality by 1.05 (p=0.008). Chronic renal failure increased death by 3.164 times (p<0.001) in the five-year mortality regression analysis. CONCLUSION: Minor amputations have an effect on one-year mortality, as do cerebrovascular disease and age. On the other hand, chronic renal failure has a negative impact on five-year mortality. Minor amputations may have a detrimental effect on mortality due to the ongoing progression of diabetic foot disease and the involvement of comorbidities. Comorbidities associated with amputations of the diabetic foot have a significant impact on mortality.

OBJECTIVE: To evaluate the usability of the ratio of birth weight to placental weight [fetoplacental ratio (FPR)] in predicting postpartum haemorrhage (PPH) and neonatal intensive care unit (NICU) admission. STUDY DESIGN: Prospective observational study. PLACE AND DURATION OF STUDY: Bursa Yuksek Ihtisas Training & Research Hospital, Bursa, Turkey, between July 2020 and July 2021. METHODOLOGY: Women who were supposed to have an uncomplicated delivery with a live, single, term pregnancy without any concomitant disease, were included in the study. Patients with PPH were accepted as the study group and patients without PPH were the control group. For NICU requirement, babies who were admitted to NICU were the study group, and babies who did not require NICU were the control group. The fetoplacental ratio was calculated by dividing the newborn weight to placental weight and evaluated in the prediction of NICU admission and PPH. RESULTS: The number of patients included in the study was 812. Approximately 7% of women had postpartum haemorrhage. The FPR was found as an independent predictor for PPH by nearly 3.5 fold. Women who experienced PPH had heavier placenta and lower fetoplacental ratio. Patients whose babies were admitted to NICU also had lower FPR with statistically significant differences. CONCLUSION: The fetoplacental ratio could be a promising predictor for PPH and NICU admission in the postpartum period. Since novel studies are needed using ultrasonographic measurements during antenatal surveillance to predict PPH or NICU admission. KEY WORDS: Birth weight, Neonatal intensive care unit, Placental weight, Postpartum haemorrhage, Cesarean birth, Vaginal birth, Fetoplacental ratio.

OBJECTIVES: The authors aimed to evaluate the characteristics and management outcomes of patients who developed tracheal stenosis after invasive mechanical ventilation (IMV) due to COVID-19. DESIGN, SETTING, AND PARTICIPANTS: The data of 7 patients with tracheal stenosis and 201 patients without tracheal stenosis after IMV due to COVID-19 between March 2020 and October 2021 were retrospectively analyzed. INTERVENTIONS: Flexible bronchoscopy was performed for the diagnosis of tracheal stenosis and the evaluation of the treatment's effectiveness, and rigid bronchoscopy was applied for the dilatation of tracheal stenosis. MEASUREMENTS AND MAIN RESULTS: In the follow-up period, tracheal stenosis was observed in 7 of 208 patients (2 women, 5 men; 3.3%). The patients were divided into 2 groups as patients with tracheal stenosis (n = 7) and patients without tracheal stenosis (n = 201). There were no statistically significant differences between the 2 groups in terms of age, sex, body mass index, and comorbidities (p > 0.05). The mean duration of IMV of the patients with tracheal stenosis was longer than patients without tracheal stenosis (27.9 ± 13 v 11.2 ± 9 days, p < 0.0001, respectively). Three (43%) of the stenoses were web-like and 4 (57%) of them were complex-type stenosis. The mean length of the stenoses was 1.81 ± 0.82 cm. Three of the patients were treated successfully with bronchoscopic dilatation, and 4 of them were treated with tracheal resection. CONCLUSIONS: Tracheal stenosis developed in 7 of 208 (3.3%) patients with COVID-19 who were treated with IMV. The most important characteristic of patients with tracheal stenosis was prolonged IMV support.

OBJECTIVES: Hamartomas are common benign tumors of the lung. Rarely, lung cancer coincidence may occur at the time of diagnosis or in the follow-up period. METHODS: Between 2016 and 2019, 38 patients who underwent a surgical procedure and diagnosed with lung hamartoma were retrospectively evaluated regarding clinicopathological features. Cases were analyzed according to age, sex, radiological findings, localization of nodules, surgical methods, and the coincidence of lung cancer. RESULTS: The mean age was 50.2±11.1 (range 28-76 years). There were 23 male (60.5%) and 15 female (39.5%) patients. Mean size was 2.7±1.8 (range 0.8-10 cm). In 28 patients, hamartoma was <3 cm in diameter (73.6%). Eighteen hamartomas were localized in the upper lobe (47.4%). Only 6 cases (15.8%) were localized at the central part of the lung. Multiple nodules were reported in 10 cases (26.3%). In 4 cases (10.5%), lung carcinoma and hamartoma were seen together at the time of diagnosis. Video-assisted thoracoscopic surgery (VATS) has been performed in 29 cases (76.3%). As a surgical method, enucleation was performed in 4 cases (10.5%), wedge resection in 28 cases (73.7%), and lobectomy in 6 cases (15.8%). No post-operative mortality appeared in the early follow-up. CONCLUSION: Pulmonary hamartomas are usually present as solitary pulmonary nodules with benign radiological findings. VATS wedge resection is a method that can be used safely in diagnosis and treatment. Hamartomas may be associated with lung cancer at the time of diagnosis or follow-up, so it should be kept in mind that a different nodule seen in patients diagnosed with hamartoma may be associated with lung cancer.
RESUMO
Associations between inherited Killer Immunoglobulin-like Receptor (KIR) genotypes and the severity of multiple RNA virus infections have been reported. This prospective study was initiated to investigate if such an association exists for COVID-19. In this cohort study performed at Ankara University, 132 COVID-19 patients (56 asymptomatic, 51 mild-intermediate, and 25 patients with severe disease) were genotyped for KIR and ligands. Ankara University Donor Registry (n:449) KIR data was used for comparison. Clinical parameters (age, gender, comorbidities, blood group antigens, inflammation biomarkers) and KIR genotypes across cohorts of asymptomatic, mild-intermediate, or severe disease were compared to construct a risk prediction model based on multivariate binary logistic regression analysis with backward elimination method. Age, blood group, number of comorbidities, CRP, D-dimer, and telomeric and centromeric KIR genotypes (tAA, tAB1, and cAB1) along with their cognate ligands were found to differ between cohorts. Two prediction models were constructed; both included age, number of comorbidities, and blood group. Inclusion of the KIR genotypes in the second prediction model exp (-3.52 + 1.56 age group - 2.74 blood group (type A vs others) + 1.26 number of comorbidities - 2.46 tAB1 with ligand + 3.17 tAA with ligand) increased the predictive performance with a 92.9% correct classification for asymptomatic and 76% for severe cases (AUC: 0.93; P < 0.0001, 95% CI 0.88, 0.99). This novel risk model, consisting of KIR genotypes with their cognate ligands, and clinical parameters but excluding earlier published inflammation-related biomarkers allow for the prediction of the severity of COVID-19 infection prior to the onset of infection. This study is listed in the National COVID-19 clinical research studies database.

OBJECTIVE: In this study, we aimed to reveal the prognostic differences between skip and non-skip metastasis mediastinal lymph node (MLN) metastasis. METHODS: A total of 202 patients (179 males and 23 females; mean age, 59.66 ± 9.89 years; range: 29-84 years) who had ipsilateral single-station MLN metastasis were analyzed in two groups retrospectively between January 2009 and December 2017: "skip ipsilateral MLN metastasis" group (sN2) (n = 55,27.3%) [N1(-), N2(+)], "non-skip ipsilateral MLN metastasis" group (nsN2) (n = 147,72.7%) [N1(+), N2(+)]. RESULTS: The mean follow-up was 42.63 ± 34.91 months (range: 2-117 months). Among all patients, and in the sN2 and nsN2 groups, the median overall survival times were 63.5 ± 4.56, 68.8 ± 7, and 59.3 ± 5.35 months, respectively, and the 5-year overall survival rates were 38.2%, 46.3%, and 36.4%. CONCLUSION: Skip metastasis did not take its rightful place in TNM classification; thus, further studies will be performed. To detect micrometastasis, future studies on skip metastasis should examine non-metastatic hilar lymph nodes (LNs) through staining methods so that heterogeneity in patient groups can be avoided, that is, to ensure that only true skip metastasis cases are included. Afterwards, more accurate and elucidative studies on skip metastasis can be achieved to propound its prognostic importance in the group of N2 disease.

OBJECTIVES: This study aims to compare the outcomes of video-assisted thoracoscopic surgery (VATS) lobectomy with open thoracotomy lobectomy in patients with non-small cell lung cancer (NSCLC). METHODS: There were 269 cases with NSCLC who underwent lobectomy between 2017-2019; these cases were retrospectively studied. VATS lobectomy (VATS Group) and open thoracotomy lobectomy (Thoracotomy Group) patients' results were compared according to the length of hospitalizations, early postoperative complications and tumor size and stages. RESULTS: VATS lobectomy was performed in 89 (33%) of these patients, whereas 180 (67%) patients underwent lobectomy using open thoracotomy for NSCLC. The findings showed that the average length of hospitalization was shorter in the VATS Group compared to the Thoracotomy Group (4 vs. 5.5 days) (p<0.05). It was found that the mean size of the tumour was smaller in the VATS Group when compared to the Thoracotomy Group (2.66 cm vs 3.97 cm) (p<0.001). Early postoperative complications were lower in the VATS Group (n=15, 16.8% vs n=58, 32.2%; p<0.021). CONCLUSION: In VATS lobectomy cases, postoperative complications are less, and the length of hospitalization is shorter. VATS lobectomy is mostly preferred smaller than 3 cm tumor size.
RESUMO
OBJECTIVES: The right sleeve lower lobectomy is the least used of the bronchial sleeve operations. There are only case-based studies in the literature. In this study, we compared this technique to those used in patients who underwent a right lower bilobectomy. METHODS: We retrospectively reviewed the data of patients who had been operated on due to non-small cell lung cancer (NSCLC) from January 2005 to December 2015 from a dataset that was formed prospectively. Of the 4,166 patients who underwent resections due to NSCLC, the files of those who had a right sleeve lower lobectomy (group S) and those who had a right lower bilobectomy (group B) were evaluated. The remaining 25 patients in group B and 18 patients in group S were compared in terms of demographic data, morbidity, hospitalization time, mortality, histopathology, recurrence, and total survival. RESULTS: No significant differences in the demographic or clinical characteristics were observed between the two groups, except that group S had more female patients. Postoperative complications developed in 52% of the patients in group B and 11.1% of the patients in group S (p = 0.006). Mean hospitalization time was 9.6 ± 3.6 (range, 6-19) days in group B and 6.72 ± 1.5 (range, 4-9) days in group S (p = 0.001). All patients received complete resections. The mean patient follow-up time was 42.9 months. No significant difference was found between local and distant recurrences (p = 1, p = 0.432). Mean survival time was 89.6 months (5-year rate = 73%), which was 90.6 months (5-year rate = 75.3%) in group B and 63.1 months (5-year rate = 69.3%) in group S (p = 0.82). CONCLUSION: This technique allows for reduced filling of the thoracic cavity by a prolonged air leak and a reduced prevalence of complications. Additionally, the hospitalization time is shortened. It does not produce any additional mortality burden, and total survival and oncological outcomes are reliable. This technique can be used in selected patients at experienced centers.

OBJECTIVES: Cervical mediastinoscopy may become essential in patients with pathological lymph nodes at mediastinum after laryngectomy. However, having had a previous tracheostomy has been reported to be a contraindication for cervical mediastinoscopy. METHODS: Between January 2010 and December 2017, cervical mediastinoscopy was performed for lung cancer staging in 1985 patients at the Department of Thoracic Surgery, Yedikule Chest Diseases and Thoracic Surgery Education and Research Hospital, Istanbul, Turkey. Eighteen of these patients (1%) had a permanent tracheostomy after total laryngectomy and cervical radiotherapy due to laryngeal carcinoma. RESULTS: Cervical mediastinoscopy was performed in 18 patients with a permanent tracheostomy after total laryngectomy. The negative predictive value of cervical mediastinoscopy was 13/14 (93%). The average operative time was 63 min (SD 12.0, range 50-90 min). The negative predictive value of endobronchial ultrasonography was 4/7 (57%). Positron emission tomography-computed tomography had a positive predictive value of 3/15 (20%) and a negative predictive value of 2/3 (67%). CONCLUSIONS: Contrary to the claims of 2 textbooks, cervical mediastinoscopy is a viable method for patients with a tracheostomy after laryngectomy. The negative predictive values of standard cervical mediastinoscopy and mediastinoscopy for patients with a tracheostomy after total laryngectomy are approximately equivalent. Our results indicate that cervical mediastinoscopy is a feasible method in patients with a permanent tracheostomy when applied by experienced thoracic surgeons in specialized hospitals.

OBJECTIVES: Turkey remains among the countries where hydatid disease is endemic. In this study, it was aimed to determine the number of operations performed for the treatment of pulmonary hydatid disease in Turkey during 2014 and to present the distribution of these operations according to the different regions of the country. MATERIALS AND METHODS: The Turkish Thoracic Society Thoracic Surgery Study Group connected with the thoracic surgeons in each city through telephone. A data set was sent by email. The age, sex, contact with animals that might be a risk of gaining the hydatid disease, the side of the disease, the type of surgical method, other organ involvement were recorded and collected from each data set to form the final data, and the results were evaluated. Turkey comprises of 81 cities that are grouped in seven different regions. The number of operations was calculated for each city and region to present the distribution. RESULTS: Overall, 101 centers from 81 cities were considered in the study. A total of 715 pulmonary hydatid cyst operations were performed in 690 patients during the study period. The most common operation technique was cystotomy and capitonnage through thoracotomy (76%). The highest incidence rate of operated patients was in the Eastern Anatolian Region (2.15 patients per 100 000 person-years). CONCLUSION: Pulmonary hydatid disease still has a high incidence rate particularly in the southeast and east of Turkey, which are mainly rural areas and where stockbreeding is very common. Cystotomy and capitonnage is still the most common surgical method used to treat pulmonary hydatid cysts. Preventive methods should be performed strictly in these cities and regions to decrease the risk of infection.
RESUMO
PURPOSE: Lung cancer is one of the major sources of mortality in the elderly. This study was undertaken to assess the early and long-term results of surgical resection in patients older than 70 years of age by comparing the results of patients aged 70-79 years (group 1) with patients older than 80 years of age (group 2). METHODS: Data on patient age, gender, spirometry values, side, size, histology and stage of the tumor, surgical procedures, postoperative complications, Charlson comorbidity scores (CCS), and survival were collected. RESULTS: After 1-2 propensity score matching group 1 (70-79 years) included 84 and group 2 (age over 80) 42 cases. The multivariate analysis showed that CCS was the only significant factor affecting the development of complications (p = 0.003). The overall median and 5-year survival of all patients were 55 months and 42.5%, respectively. Although the survival of the elderly group 2 was higher than the first group, the difference did not reach significance (50 vs. 49 months, respectively). CONCLUSION: The outcomes of surgery in terms of morbidity and mortality rates do not differ between the two age groups. The safety of pulmonary resections in the elderly group is comparable to patients under 70 years if the comorbidities are appropriately controlled. In addition, surgery provides satisfactory survival rates in both age groups.

OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has become the standard treatment method for primary spontaneous pneumothorax. Concerns about lesser pain and better cosmesis led to the evolution of uniportal access. This study prospectively compared the results of the uniportal, two-port, and three-port thoracoscopic surgery. MATERIAL AND METHODS: One hundred and thirty-five patients were randomized into three groups according to the port numbers. The groups were compared regarding the operation time, hospital stay, amount of drainage, area of pleurectomy, complications, recurrences, and pain scores. RESULTS: Except for the amount of drainage (p = 0.03), no factors were found to be statistically significant. The overall recurrence rate was 5%. Although the first and second week pain scores were not statistically significant, the single-incision group patients had significantly less pain at 4, 24, and 72 hours (p < 0.05). CONCLUSION: The study indicated that uniportal VATS approach is less painful and has better cosmetic results, besides it is as efficient as two- or three-port VATS approach.

PURPOSES: Since radiation and chemotherapy have limitations as therapies for malignant pleural mesothelioma (MPM). The type of surgery [extrapleural pneumonectomy (EPP), extended pleurectomy (E/P), and pleurectomy/decortication (P/D)] remains controversial. METHODS: This study involves 76 consecutive patients. 58 of the cases were males (76%) with a median age of 53.17±10.93 years. EPP, E/P, and P/D were performed in 31, 20, and 25 cases, respectively. RESULTS: The median survival time was 20 months in all patients. Overall, five-year survival rate was 14.3%. The survival rate was significantly better in epithelioid mesothelioma (P=0.049). For EPP cases, the median survival rate was 17 months, and the three-to-five year survival rates were 21% and 17%, respectively. For E/P cases, the median survival rate was 27 months and the three-year and four-year survival rates were 34% and 30%, respectively. For P/D cases, the median survival rate was 15 months and the three-to-five year survival rate was 13% and 0%. There were no statistically significant differences between the three surgical techniques (P=0.088). A comparative analysis indicates only a statistically significant difference in the E/P and P/D comparison (P=0.032). Hospital mortality showed a higher trend in EPP group (EPP: 12.9%, E/P: 0% and P/D: 4%, P=0.145). N2 cases, there were no cases of two-year survival. The survival rate in N2 was comparatively much lower, which was statistically significant (P=0.005). In multivariate analysis, only P/D (OR 0.3, 95% CI: 0.1-0.9, P=0.049) and N2 (OR 1.6, 95% CI: 0.9-2.6, P=0.090) were found to be poor prognostic factors. CONCLUSIONS: E/P could be encouraged to EPP with lower mortality rate and better survival trend in MPM. N2 diseases were negative prognostic factors in MPM.
RESUMO
Castleman's disease (CD) is a rare disease with unknown aetiology. It is characterised by benign lymph node hyperplasia that may involve all lymph nodes. The most common locations are the mediastinum and abdomen. CD arising from intrapulmonary lymph nodes has been reported in five cases, in the English language literature to date. Tumours in these patients are usually resected during lung surgery. An asymptomatic 29-year-old male patient was evaluated due to a mass lesion with a diameter of 55 mm located in the infrahilar region of the right lung with a high degree of contrast enhancement on thoracic computed tomography (CT). Vascularity of this central lesion was excluded by pulmonary angiography. Thoracotomy was performed due to the inability to obtain a diagnosis with percutaneous fine needle aspiration biopsies. A frozen section examination of the mass revealed a benign lesion, arising from the intrapulmonary lymph nodes and protruding to the lower-lobe parenchyma. The mass was then extracted from the parenchyma. After histopathological evaluation of the mass, CD involving the lymph nodes was diagnosed. CD rarely involves the intrapulmonary lymph nodes. Diagnosis is difficult in these patients, and thoracotomy may be required. After obtaining benign results by mass sampling, limited resection of these masses, while sparing the lung parenchyma, may be possible.
