The Effect of Helicobacter pylori on Gastric Cancer Treated with Adjuvant Chemotherapy After Curative Resection

Helicobacter pylori has been associated with diverse pathologies of varying severity. We investigated the H. pylori infection status and its association with the pathologic features and clinical outcomes in stage III gastric cancer patients treated with adjuvant therapy after curative resection. Between 2004 and 2009, the records of 76 consecutive patients were retrospectively reviewed. H. pylori infection was confirmed by examination of pathological specimen. The relationship between H. pylori and the clinicopathological features was analyzed by Fisher exact test, Student’s t test, and Kaplan-Meier method. Of the 76 patients, 16 patients (21.1 %) were confirmed for H. pylori infection. The median age was 59 years. Twenty-three patients received chemotherapy and remainder received chemoradiotherapy. H. pylori status did not correlate with the clinicopathologic features. It was greater in non-neoplastic tissue than the tumor tissue (21.1 vs 7.9 %). Median follow-up was 21 months. During this period, 88.2 % patients had experienced tumor recurrence, and 85.5 % patients had died. Recurrence was observed in 87.5 % patients and in 88.3 % patients in H. pylori-positive and H. pylori-negative patients, respectively (P = 0.92). Disease-free survival was 28.4 ± 7.9 months and overall survival was 31.5 ± 7.4 months in H. pylori-positive patients compared with 28.3 ± 3.7 and 33.2 ± 3.4 months, respectively, in H. pylori-negative patients. H. pylori infection status did not have effect on the overall or disease-free survival (p = 0.85 and P = 0.86), respectively. H. pylori status might not be useful as a prognostic and predictive factor for clinical outcomes.     

Prognostic importance of tumor angiogenesis in breast carcinoma with adjuvant chemotherapy

Tumor angiogenesis is believed to be related to prognostic factors involved in tumor development and metastasis. Using immunohistochemical methods, we evaluated tumor angiogenesis in 42 early invasive breast cancer patients (T1-2, NO-1-2, M0). Four patients received tamoxifen, 25 patients received CAF or CA, and 15 patients received CMF as adjuvant therapy. The median follow-up was 47 (range 24-119) months. Ten patients (43.5%) in the node-positive group and 2 patients (10.5%) in the node-negative group relapsed (p = 0.019). The mean microvessel count (MVC) was 60.3 3.05 per 200x field (range: 16-95). MVCs of postmenopausal and premenopausal patients were 50.13 +/- 5.74 and 68.64 +/- 4.11, respectively, in the axillary lymph node (ALN)-negative patient group (p = 0.04). Staining was moderate to strong in 13 (68%) ALN-negative and in 17 (74%) ALN-positive patients (p > 0.05), and was also moderate to strong in 82% of premenopausal patients and in 50% of postmenopausal patients (p = 0.037). There was no significant relationship between angiogenesis and p53, nor was angiogenesis significantly associated with the patient ER status and tumor size. No significant correlations were found between OS/DFS and Factor VIII staining or p53 (log rank test, p > 0.05). Of all ALN-negative patients with increased angiogenesis, one patient of the CMF group relapsed, but no recurrence occurred in patients undergoing anthracycline-based chemotherapy (p > 0.05). On the other hand, of all ALN-positive patients with increased angiogenesis, 5/14 patients treated with anthracylcine and 2/2 CMF-treated patients relapsed (p = 0.175). Despite the statistical insignificance, anthracycline-based adjuvant chemotherapy appears to be more effective than CMF as regards relapse prevention particularly in early ALN-positive breast cancer patients with increased angiogenesis. Additional studies are necessary to demonstrate the clinical importance of angiogenesis.     

Recurrent retroperitoneal cystic lymphangioma

Retroperitoneal cystic lymphangioma is a rare congenital malformation. The majority of lymphangiomas are present at birth and nearly all present before the age of two years. We report a case of giant cystic retroperitoneal lymphangioma in a patient who first presented with symptoms at the age of 7, underwent surgery, and who then suffered a recurrent mass 11 years later.     

Pelvic inflammatory disease and intrauterine devices: Prophylactic antibiotics to reduce febrile complications

In the present study, we tried to determine whether IUD insertion related PID and febrile complications could, be prevented by prophylactic use of antibiotics. We studied 300 patients who were admitted to our family planning clinic for IUD contraception. Of these, 150 patients received prophylactic Doxycycline (group 1) and the second 150 received no therapy (group 2). Five cases experienced fever with or without leucocytosis and none required hospitalization. PID was observed in one woman in each group.Positive culture (gonorrhea) was obtained in one woman who was then treated by relevant, antibiotics; the other woman required hospitalization for two days. The overall infection rates for group 1 and 2 were 2.1% and 2.9%, respectively and this difference was not significant. The incidence of PID infection and febrile complications was found to be very low for both groups when compared to other studies, suggesting that aseptic conditions with proper insertion reduce the risk of infection.

Resumen En el presente estudio, intentamos determinar si la inflamación pélvica y las complicationes febriles relacionadas con la inserción, de DIU podían evitarse mediante la administración profiláctica de antibióticos. Estudiamos a 300 pacientes de nuestra clínica de planificación familiar que recibieron DIU. Se administró un tratamiento profiláctico de doxicilina a 150 pacientes (Grupo 1) mientras que las restantes no recibieron ningún tratamiento (Grupo 2). Hubo cinco casos de fiebre con o sin leucocitosis pero ninguno requirió hospitalización. La inflamación pélvica se observó en dos casos, uno de cada grupo. Se obtuvo un cultivo positivo (gonorrea) en uno de los casos, que fue tratado con antibióticos apropiados, y el segundo caso debió ser hospitalizado durante dos días. Las tasas generales de infección fueron para el Grupo 1 y el Grupo 2, respectivamente, del 2,1% y del 2,9%, diferencia que no es significativa. Una comparación con otros estudios permitió verificar que la incidencia de infección pélvica inflamatoria y complicaciones febriles era muy baja en los dos grupos, lo cual hace pensar que las condiciones de asepsia y la inserción correcta reducen el riesgo de infección.

Resumé Dans la présente étude, nous avons tenté de déterminer si l'inflammation pelvienne et les complications fébriles liées à l'insertion de DIU pouvaient être évitées par une administration prophylactique d'antibiotiques. Nous avons suivi 300 patientes de notre clinique de planning familial, admises pour l'insertion, de DIU. Un traitement prophylactique de doxycycline a été administré à 150 de ces patientes (Groupe 1) et les autres n'ont reçu aucune, thérapie (Groupe 2). Nous avons eu cinq cas de fièvre avec ou sans leucocytose mais aucune de ces femmes n'a d être hospitalisée. L'inflammation pelvienne s'est manifestée dans deux cas, un dans chaque groupe. Une culture positive (gonorrhée) a été obtenue chez une de ces patientes, à laquelle un traitement aux antibiotiques appropriés a été administré, et la seconde a d être hospitalisée pendant deux jours. Les taux globaux d'infection ont été, respectivement pour le groupe 1 et le groupe 2, de 2,1% et 2,9%, ce qui ne représente pas une différence significative. Une comparaison avec d'autres études a permis, de constater que l'incidence d'infection pelvienne inflammatoire et de complications fébriles était très faible dans les deux groupes, ce qui laisse penser que les conditions d'asepsie et une insertion correcte réduisent le risque d'infection.

     

Anxiety and depression levels of healthcare workers during Covid-19 pandemic

BackgroundCoronavirus disease 2019 (covid-19), which causes a pandemic in the world, has started to appear in turkey since march 2020. Healthcare workers are at the top of the groups most at risk for covid-19 infection, which can have a negative impact on psychological state.ObjectivesIt was aimed to evaluate anxiety and depression levels among healthcare workers.Methodsthis cross-sectional study performed via an online survey in april 2020. Participants answered questions about sociodemographic features, personal views and experiences about covid-19 and the hospital anxiety and depression scale (hads).ResultsA total of 300 healthcare workers,193 men and 107 women, participated in the survey. According to hads, 44.6% of participants scored above anxiety and 68.2% scored above depression cut-off points. Being younger than 50 and taking care of covid-19 patients in hospitals were independently associated with anxiety risk. Female gender, young age (less than 50) and having comorbidity were independent risk factors for depression.ConclusionHealthcare workers were at high risk of anxiety and depression during covid-19 outbreak. For this reason, psychological support should be given, especially to the group with high risk.

Coronary artery bypass surgery in patients with severe left ventricular dysfunction

Objective: The role of coronary artery bypass grafting (CABG) in patients with severe left ventricular dysfunction was evaluated. Methods: Two hundred and twelve patients (152 men, 60 women; age 35 to 82, mean 55) with ejection fraction (EF) of less than 30% underwent CABG between January 1996 and February 2001 by a single surgeon (SA). They compromised of 12% of 1759 patients operated on in this period. EF ranged from 17% to 30% (mean 25%). Preoperatively 68% had congestive heart failure and 72% had severe angina (CCS 3 or 4). A left main lesion was found in 26% of the cases. The mean number of grafts was 3.18 per patient. The left internal mammary artery (LIMA) was used on 107 patients (50.4%). Preoperative intraaortic balloon pump (IABP) was used on 32 patients (15%). Endarterectomy was performed on 53 patients (25%). The patients were followed for up to 58 months (mean 28.7). Results: Twelve patients died in hospital (5.6%). Survival was 94%, 87%, 80% and 73% at 1, 2, 3 and 4 years respectively. Among the preoperative variables survival was negatively affected by chronic renal failure, older age, congestive heart failure, elevated pulmonary artery pressure and recent myocardial infarction, by means of multivariate analysis. Preoperative IABP support improved the operative mortality significantly (P=0.002). Use of LIMA did not have any influence on survival. Conclusion: CABG on patients with poor left ventricular function: (1) Can be performed with an acceptable mortality. (2) Mid term results are encouraging. (3) Preoperative IABP support improves the chance of survival.
