Evaluation of low tidal volume with positive end-expiratory pressure application effects on arterial blood gases during laparoscopic surgery.

Background: Pneumoperitoneum (PNP) and patient positions required for laparoscopy can induce pathophysiological changes that complicate anesthetic management during laparoscopic procedures. This study investigated whether low tidal volume and positive end‐expiratory pressure (PEEP) application can improve ventilatory and oxygenation parameters during laparoscopic surgery. Methods: A total of 60 patients undergoing laparoscopic surgery were randomized to either the conventional group (n = 30, tidal volume = 10 mL/kg, rate = 12/minute, PEEP = 0 cm H2O) or the low tidal group with PEEP group (n = 30, tidal volume = 6 mL/kg, rate = 18/minute, PEEP = 5 cm H2O) at maintenance of anesthesia. Hemodynamic parameters, peak plateau pressure (Pplat) and arterial blood gases results were recorded before and after PNP. Results: There was a significant increase in the partial pressure of arterial carbon dioxide (PaCO2) values after PNP in the conventional group in the reverse Trendelenburg (41.28 mmHg) and Trendelenburg positions (44.80 mmHg;p = 0.001), but there was no difference in the low tidal group at any of the positions (36.46 and 38.56, respectively). We saw that PaO2 values recorded before PNP were significantly higher than the values recorded 1 hour after PNP in the two groups at all positions. No significant difference was seen in peak inspiratory pressure (Ppeak) at the reverse Trendelenburg position before and after PNP between the groups, but there was a significant increase at the Trendelenburg position in both groups (conventional; 21.67 cm H2O, p = 0.041, low tidal; 23.67 cm H2O, p = 0.004). However, Pplat values did not change before and after PNP in the two groups at all positions. Conclusion: The application of low tidal volume + PEEP + high respiratory rate during laparoscopic surgeries may be considered to improve good results of arterial blood gases.

Could the Platelet-to-Lymphocyte Ratio be a Novel Marker for Predicting Invasiveness of Cervical Pathologies?

PURPOSE To determine whether the preoperative platelet to lymphocyte ratio (PLR) could predict invasiveness of cervical pathologies. MATERIALS AND METHODS Patients with preinvasive and invasive diseases were reviewed retrospectively, over a nine-year period, 2005-2014. The pathological records and completed blood counts of the patients were collected and recorded in the SPSS program. Patients were divided in two groups, preinvasive and invasive. RESULTS The median PLR was significantly higher in the invasive group than in the preinvasive group (p=0.03). There was a correlation between invasion of cervical cancer and white blood cell count, red cell distributing width (RDW), neutrophil-lymphocyte ratio (NLR), and PLR. CONCLUSIONS This study showed that patients with uterine cervical cancer may present with leukocytosis, increased RDW, NLR and PLR. These cheap and easily available parameters, especially PLR, may provide useful information about the invasiveness of cervical lesions.

Perinatal outcomes of borderline diabetic pregnant women.

Abstract We examined the perinatal outcomes of borderline diabetic pregnant women who had impaired 50 g oral glucose challenge test (OGCT) results, but normal 100 g oral glucose tolerance test (OGTT) results. Our study group included 70 pregnant women who had increased 50 g OGCT results, but normal 100 g OGTT results, and a control group of 122 pregnant women with normal 50 g OGCT results. Polyhydramnios, macrosomia and neonatal birth weight were significantly higher in the study group. After adjusting the results for possibly affecting variables, the risk of polyhydramnios remained significant, while the risk of macrosomia and neonatal birth weight was not significant between the groups. The results from the study group were similar to the control group, when adjusted for other risk factors. Increased 50 g OGCT results in pregnant women can be accepted as a benign state if the 100 g OGTT results are normal.

Plasma L-carnitine levels of obese and non-obese polycystic ovary syndrome patients

Abstract It is well-known that plasma L-carnitine concentrations are significantly decreased in obese individuals. A study showed that L-carnitine concentrations are significantly lower in lean PCOS patients than in lean healthy women. Thus, it has been suggested that lowered L-carnitine is associated with PCOS. This study also showed that the women with PCOS had significantly lower L-carnitine levels than those of the healthy controls. In addition, this study hypothesised that low L-carnitine levels in PCOS patients were associated with obesity and/or insulin resistance. Moreover, plasma L-carnitine concentrations were found to be statistically similar in PCOS patients and healthy controls, when controlled for obesity. This study implied that L-carnitine could be used as an adjunctive therapy in the management of insulin resistance or obesity in women who have PCOS. Further research might be planned to clarify the clinical effects of L-carnitine administration in PCOS patients with insulin resistance and/or obesity.

Very rare cause of vaginal mass in pregnancy: Cavernous hemangioma

Vaginal cavernous hemangioma is a considerably rare condition during pregnancy. There has only been one reported case to date. A multiparous, 24‐year‐old woman in the 32nd week of pregnancy was admitted with a mass prolapsed from the vagina, which had suddenly increased in size over the previous few days. A necrotic mass obstructing the vaginal canal and originating from the posterior wall was observed in a pelvic physical examination and carefully excised. The patient had contractions after the intervention and was administered tocolytic treatment with bed‐rest and fluids. Her obstetric clinical status was stable after treatment and she gave birth without complication at 37 weeks and 5 days from the vaginal canal. The main approach to these very rare tumors of pregnancy, especially in the presence of necrosis, infection and/or obstruction, should be excision. But the potential for increased blood loss that may occur due to the hypervascular structure of the tumor should be taken into account.

Two-Year Follow-Up Results of Transobturator Tape Procedure with and without Concomitant Vaginal Surgery

Objective: This study aims to evaluate the subjective and objective outcomes of the transobturator tape (TOT) procedure performed to treat stress urinary incontinence and to determine the efficacy and safety of the TOT procedure when used along with vaginal surgery. Methods: This is a prospective review of 24 women who had the TOT procedure done only due to stress incontinence; 22 women who underwent concomitant TOT and pelvic floor repair; and 20 women who received concurrent TOT, transvaginal hysterectomy, and sacrospinous ligament fixation. Results: When compared to the patients who had TOT with pelvic floor repair, the patients who underwent TOT with hysterectomy declared to have more dyspareunia (p = 0.008) and they were found to have significantly higher post-void residual volume (p = 0.014). When compared to the patients who had only TOT, the patients who underwent TOT with hysterectomy claimed to have more pelvic pain (p = 0.012) and significantly higher post-void residual volume (p = 0.020). Conclusion: The TOT procedure results in moderately high objective cure rates, and concurrent application of pelvic floor repair or transvaginal hysterectomy does not affect these rates. The relatively higher incidences for voiding problems and pelvic pain in women who underwent TOT, hysterectomy, and sacropinous fixation simultaneously suggest that the extent of surgery directly correlates with the severity of postoperative complications.

Very rare cause of hemoperitoneum: Ovarian fibroma

Ovarian fibromas are benign tumours classified as sex cordstromal tumours. They constitute about 2% of all ovarian tumours. They are generally observed in middle-aged women (Maccıo et al. 2014). They may be asymptomatic without any typical clinical signs. However, they may result in a clinical picture, namely Meigs’ syndrome, which includes ovarian fibroma, free ascites and hydrothorax in 1–3% of the cases (Meigs 1954). An increase in the level of CA 125 rarely accompanies this clinical picture; in addition, haemoperitoneum is a very rare situation. We present a case of ovarian fibroma, in which the preoperative benign or malignant nature could not be determined, and presented with hemoperitoneum.
