Laparoscopic radical hysterectomy and total vaginectomy for vaginal malignant melanoma with cervical metastasis

The presented case is a 63-years-old multiparous woman admitted with the complaint of postmenopausal bleeding. On gynecologic examination multifocal lesions were detected, including 1 cm on lateral vaginal wall, 4 cm on posterior vaginal wall and 0.5 cm on the left lateral part of the cervix. Histopathology examination gave a diagnosis of epithelioid malignant melanoma. Consequently, laparoscopic radical hysterectomy and total vaginectomy with bilateral pelvic and inguinofemoral lymph node dissection were planned. On both sides, pararectal and paravesical spaces were created and the ureter was identified. Then, the vesicouterine and vesicovaginal spaces were developed. Uterine artery and superior vesical artery were coagulated, cut and the lateral parametrium was prepared. The left ureter was dissected and the ureteral tunnel was unroofed up to the bladder entrance. Subsequently, the anterolateral parametrium was transected. Then, the infundibulopelvic and sacrouterine ligaments were sealed and transected. At this time, the rectovaginal space was developed. Bilateral paracolpos were transected. The endopelvic fascia with the levator muscles were sealed and cut circumferentially. Anteriorly, the pubovesicocervical fascia was transected and the bladder was mobilized up to the uretrovesical junction. Thereafter, through a vaginal approach, the cervix and vagina were inverted by grasping the cervix with a tenaculum. An incision on the posterior vaginal wall at the introitus was made and the urogenital diaphragm was dissected to connect with the pelvic cavity. The vaginal entrance was cut circumferentially and the surgical specimen was extracted. In conclusion, laparoscopy can be considered as a feasible approach for radical hysterectomy and total vaginectomy in selected patients.

Investigation of taurine and aqueous garlic extract diet supplementation effect on the healing of rat osteoporotic fractures.

BACKGROUND: We have evaluated the effects of taurine and aqueous garlic extract (AGE) as a dietary supplement on osteoporotic fracture (OPF) healing in the ovariectomized rat femur fracture model. METHODS: In this experimental animal study,twenty-four osteoporosis-remodeled female Wistar albino rats were randomly divided into 3 groups (n: 8) according to their supplemented diet; control, taurine, and AGE groups. Unilateral femur middiaphysis mini-open osteotomy was stabilized with Kirschner wires. Six weeks after osteotomy, the rats were sacrificed before the femurs were harvested and OPF healing was evaluated with biochemical, histologic, microcomputed-tomography, and scintigraphic methods. RESULTS: As an indicator of the antiosteoporotic effect, the calcium levels of the taurine group were significantly lower than the AGE and control groups in biochemical analyzes (p < 0.01). In histological studies, the new bone diameter and new bone volume values of the taurine group were significantly higher than the control group (p = 0.002 and p = 0.032, respectively), while higher trabecular-compact callus was observed in the taurine and AGE groups, respectively, compared to the control group. In morphological analyses, taurine and AGE groups had significantly higher bone volume/tissue volume, trabecular number, bone surface density, and lower trabecular separation than the control group (p < 0.05). The scintigraphic imaging showed a significant increase in osteoblastic activity of the taurine group compared to the control group (p = 0.005). DISCUSSION: Taurine and AGE have positive anabolic effects, respectively, on the healing of OPFs, demonstrated by biochemical, histological, morphological, and scintigraphic methods.

A rare lesion that mimics a bone tumor: Osseous hydatidosis.

OBJECTIVES: This study aims to evaluate the symptoms, skeletal manifestations, and management of patients with tumor-like osseous hydatidosis treated in our oncology clinic in the long term and to share our clinical experience with this extremely rare disease. PATIENTS AND METHODS: Between December 2010 and May 2019, a total of 11 patients (6 males, 5 females; mean age: 45.1±13 years; range, 22 to 70 years) who were treated with a bone hydatid cyst (HC) and followed were retrospectively analyzed. Epidemiological, clinical, diagnostic, and therapeutic data of the patients with long-term follow-up were collected. RESULTS: The mean follow-up was 63.2±23.9 (range, 24 to 101) months. The most common site of bone hydatidosis was the femur in four (36%) patients. The most common clinical presentation was pain in seven (63.6%) patients. Two (18.2%) patients had a pathological fracture of the femur. It was detected incidentally in two patients. Contact history was present in two patients (with dog), and two (18.2%) patients had concomitant extraosseous cystic echinococcosis in the liver. Complete blood count analysis was performed in all patients and eosinophilia was positive in three (27.3%) patients. As treatment, curettage cementation was performed in nine (81%) patients (internal fixation was also applied to five of them), while wide resection and prosthesis were applied to two (18.2%) patients. CONCLUSION: The diagnosis of osseous hydatidosis is difficult and the prognosis is often poor. This entity should be kept in mind for the differential diagnosis of the cystic or tumoral lesions of the bone.

The incidence of biliary sludge in first trimester pregnancies with hyperemesis gravidarum and its effect on the course of hyperemesis gravidarum.

Pregnancy is one of the risk factors for biliary sludge (BS) formation. In this cross-sectional study, a total of 959 pregnant women were included. Serum aspartate aminotransferase, alanine aminotransferase, sodium, potassium, triglycerides, cholesterol levels and the presence of ketones in urine were determined. The presence of BS was investigated using maternal abdominal ultrasound. The incidence of BS in pregnancies complicated by hyperemesis gravidarum (HG) was 14%. The degree of ketonuria and low birth weight were statistically higher in pregnancies with maternal BS than women without sludge. Total weight gain during pregnancies with BS was statistically lower than controls. The incidence of BS in pregnancies with HG does not appear to increase due to HG-related complications, such as dehydration, starvation and weight loss. However, the severity of HG may be worse when HG is associated with sludge.Impact StatementWhat is already known on this subject? The incidence of biliary sludge (BS) in pregnant women ranges between 10.9% and 36%. Some clinical conditions, such as pregnancy, prolonged fasting, total parenteral nutrition, rapid weight loss and ceftriaxone treatment can play a role in the formation of gallbladder sludge.What do the results of this study add? This is the first study to investigate the incidence of BS in hyperemesis gravidarum (HG) pregnancies. Results show that HG may transiently be associated with BS. HG is more likely to cause a transient increase in new sludge formation. The symptoms and complications related to HG may be more severe when HG is associated with BS.What are the implications of these findings for clinical practice and/or further research? Our study showed that BS can be found in HG patients, and HG can be a predisposing factor for new sludge formation, although this association is generally driven by advanced maternal age and increased baseline serum lipid and alanine aminotransferase levels. BS may also be independently associated with an increased risk of subsequent preterm delivery in women with HG.

Are preoperative complete blood count parameters in peripheral nerve sheath tumors useful diagnostic tools?

OBJECTIVES: This study aims to evaluate the diagnostic value of complete blood count (CBC) parameters in patients with peripheral nerve sheath tumors (PNSTs). PATIENTS AND METHODS: A total of 181 patients (83 males, 98 females; median age: 44 years; range, 15 to 83 years) who underwent surgical treatment for PNSTs in our tertiary oncology center between January 2010 and December 2019 were retrospectively analyzed. Eighty-two patients were diagnosed with a neurofibroma, 79 with a schwannoma, and 20 with a malignant PNST (MPNST). The patient group was evaluated as malignant (n=20) and benign (n=161). Age- and sex-matched patients admitted to our outpatient clinic of orthopedic and traumatology with non-specific symptoms other than tumor, infection, fracture, and rheumatological or hematological diseases were included as the control group (n=165). Data including age, sex, definitive histopathological diagnosis, and pre-treatment CBC values were obtained from the hospital records. Pre-treatment CBC values such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) were calculated for both malignant and benign groups and control groups. Diagnostic values of NLR, PLR, and LMR between PNST groups were assessed using the receiver operating characteristic (ROC) curve analysis. RESULTS: Neurofibroma, schwannoma, and MNPST groups had significantly higher median NLR, compared to the control group (p<0.001), while the median LMR was significantly lower in these groups (p<0.05). However, the median PLR was higher only in the MPNST group, compared to the control group (p<0.001). Post-hoc analyses revealed that median NLR, PLR, and LMR ratios were similar in PNST groups, compared to the control group. In addition, the median NLR, PLR, and LMR ratios were similar between malignant and benign patient groups. The highest area under the curve (AUC) was found for NLR (AUC=0.756) and LMR (AUC=0.716) in the MPNST group. CONCLUSION: Our study results suggest that NLR, PLR, and LMR may have an added value in the early diagnosis of PNSTs and are valuable for differentiating patients from healthy individuals, although their value in differential diagnosis is still unclear.

Temporary Clamping of Bilateral Common Iliac Artery During Cesarean Hysterectomy for the Management of Placenta Percreta.

OBJECTIVE: To evaluate whether bilateral common iliac artery (CIA) temporary clamping reduces blood loss during cesarean-hysterectomy of placenta percreta cases. STUDY DESIGN: A total of 32 women, who underwent cesarean-hysterectomy under bilateral CIA temporary clamping (n = 12) and without any arterial clamping or ligation (control group, n = 20) due to placenta percreta in Gaziantep University Hospital were retrospectively evaluated. The intra- and postoperative outcomes such as blood loss, blood transfusion and complications were compared between the two groups. RESULTS: Age, parity, body-mass-index and gestational-age were similar in the two groups. The estimated blood loss was lower in the temporary clamping of CIA group than the control group (595 ± 172 mL vs 1450 ± 662 mL, P < 0.001). The number of intraoperative packed-red-blood-cells (0.17 ± 0.58 units vs 1.85 ± 1.46 units, P = 0.002) and fresh-frozen-plasma (0.17 ± 0.58 units vs 1.7 ± 1.49 units, P = 0.005) transfusions were lower in the CIA temporary clamping group than the control group. The rate of women, who received blood/blood products were significantly lower in the CIA temporary clamping group compared to the control group (75 % vs 16 %, P = 0.001). Duration of operation was longer in the CIA temporary clamping group (140 ± 38 min vs 90 ± 25 min, p = 0.001). No complication or maternal death was encountered during this study. CONCLUSION: Bilateral CIA temporary clamping method reduces the intraoperative blood loss and the amount of intraoperative blood/blood product transfusions during cesarean-hysterectomy due to placenta percreta.

Comparison Between the Two-Injection Technique and the Four-Injection Technique in Axillary Brachial Plexus Block with Articaine.

OBJECTIVE: In this study, we aimed to compare axillary brachial plexus block using the two-injection and four-injection techniques assisted with ultrasonography (USG) and nerve stimulator in patients operated for carpal tunnel syndrome with articaine. To evaluate which technique is more effective, we compared the onset time, effectiveness, and duration of block procedures, patient satisfaction, adverse effect of the drug, and complication rates of the motor and sensory blocks. METHODS: Sixty patients were randomly divided into two groups. A mixture of physiologic serum added to articain with NaHCO3 (30 mL) was injected into the patients' axilla in both the groups. After the blockage of the musculocutaneous nerve in both the groups, the median nerve in the two-injection group and the median nerve, ulnar nerve, and radial nerve in the four-injection group were blocked. In brachial plexus nerves, sensorial blockage was evaluated with pinprick test, and motor block was evaluated by contraction of the muscles innervated by each nerve. The adverse effects and complications, visual analog scale (VAS) values during the operation, and post-operative patient satisfaction were recorded. RESULTS: Sufficient analgesia and anaesthesia were achieved with no need for an additional local anaesthetics in both the groups. Furthermore, additional sedation requirements were found to be similar in both the groups. A faster rate and a more effective complete block were achieved in more patients from the four-injection group. In the two-injection group, the block could not be achieved for N. radialis in one patient. All other nerves were successfully blocked. Whereas the blockage procedure lasted longer in the four-injection group, the VAS values recorded during the blockage procedure were higher in the four-injection group. No statistical difference was found with regard to patient satisfaction, and no adverse effects and complications were observed in any group. CONCLUSION: Although the multi-injection method takes more time, it provides faster anaesthesia and more complete blockage than the two-injection method used with articain. The two-injection method can also be used in specific surgery such as for carpal tunnel syndrome, as an alternative to multi-injection method.

Continuous Spinal Anaesthesia for Hip Fracture Surgery in a High-Risk Patient.

Elderly patients have increased risk for perioperative mortality and morbidity due to additional comorbidities, such as cardiac diseases. Regional anaesthesia techniques are usually preferred in high-risk patients due to some advantages, such as the maintenance of cardiovascular stability and early postoperative mobilisation. This case presents the anaesthetic approach in a 55-year-old male patient with low ejection fraction that underwent hip fracture surgery. In this present case, continuous spinal anaesthesia with low-dose hyperbaric bupivacaine provided safe and effective anaesthesia during surgery with minimal haemodynamic changes and adequate analgesia during the first 24 hours after surgery.

Balloon tamponade for the management of postpartum uterine hemorrhage.

OBJECTIVE: To evaluate the use of the Bakri balloon in postpartum hemorrhage (PPH) resistant to medical treatment. METHODS: The Bakri balloon was applied to 45 women with PPH after failure of initial management. Bilateral internal iliac artery ligation (BIIAL) and hysterectomy were performed if necessary. RESULTS: The Bakri balloon was applied in 45 women; an additional BIIAL was required in nine women. The mean inflation volume of the Bakri balloon was 571±264 mL (range: 240-1300 mL). Hemostasis was achieved in 34 (75.5%) women with the Bakri balloon alone, and in six women with an additional BIIAL. The Bakri balloon was effective with additional procedures overall in 40 of 45 (88.8%) women. In 34 women with uterine atony, the Bakri balloon was successful alone in 27 (79.4%) and with an additional BIIAL in 30 (88.2%) women. An inflation volume of >500 mL was necessary in 18 women with uterine atony. CONCLUSION: The Bakri balloon may be performed as a first line of treatment for PPH resistant to uterotonic agents, and can be used not only in tertiary centers but also in limited-resource centers. The inflation volume of the Bakri balloon should be adjusted according to the type of PPH; a volume exceeding 500 mL may be necessary in uterine atony.

Biomechanical evaluation of different fixation plates in medial opening upper tibial osteotomy.

In this biomechanical study, 25 in vitro calf tibial models were used in order to compare the stability of the plates under axial compression loading. A 10-mm medial opening gap was stabilized in each of the five calf tibial models either with four or two-holed rectangular shaped plates with wedges, with four-holed reversed L-shaped plates with wedges, with the combination of these two types of plates, or with six-holed anatomical T-plates. The compression behavior of the model was tested by using a universal mechanical testing system. The specimens fixed with the combination of plates with the four-holed reversed L-shaped and with two-holed rectangular shaped; or with six-holed anatomical T-plates, showed significantly better stability than those of others. Four different kinds of failure (slippage of wedge, lateral cortex fracture, damage and/or loosening of screws, and bending of plates) were observed on the models. When the average value of force loading on the plates that were designed by the first author was considered, the plates were stable and the average force values at these points were higher than the loading force on a knee during the normal paced walking or running conditions.

[Assessment of the vulnerability of the proximal tibiofibular joint to injury during osteotomies]. / Osteotomilerde proksimal tibiofibular eklemin yaralanma riskinin degerlendirilmesi.

OBJECTIVES: We evaluated the dimensions and anatomic localization of the proximal tibiofibular joint (PTFJ) in human cadaver and amputated knees. In addition, we assessed the relation between the osteotomy line and the PTFJ and its vulnerability to injury on radiographs of patients after proximal tibial medial open wedge osteotomy (PT-MOWO). METHODS: In the first phase, dimensions of the tibial part of the PTFJ lying between the lateral tibial condyle and the fibular head were measured by digital calipers in six human cadaver and six fresh amputed tibiae (4 females, 8 males; mean age 57 years) to evaluate the relation between the tibial surface of the PTFJ and the posterior part of the lateral tibial plateau. In the second phase, anteroposterior, lateral, and medial oblique radiographs were assessed with respect to the relation of the osteotomies with the PTFJ following PT-MOWO in 46 knees of 44 consecutive patients (38 females, 6 males; mean age 51 years). RESULTS: On cadaver and fresh amputation materials, the mean long and short axis dimensions of the ellipsoidal articular surface of the PTFJ in the posterolateral aspect of the tibial plateau measured 18.8 mm (range 13 mm to 20 mm) and 14.9 mm (13 mm-17 mm), respectively. The upper articular border lied at a mean of 6.3 mm (2 mm to 11 mm) distal to the posterior border of the articular surface of the lateral tibial plateau. Medial oblique radiographs showed that the osteotomy line extended to the PTFJ in cases in which it was proximally located, particularly in three cases (6.5%) where lateral cortex continuity was interrupted. CONCLUSION: The osteotomy line may encroach upon the PTFJ unless preoperative oblique radiographs are evaluated and a parallel course to the tibial slope of the lateral tibial plateau is followed. In addition, insufficient evaluation of PT-MOWO candidates may result in damage to the lateral cortex, which increases the risk for injury to the PTFJ.
