The use of percutaneous cholecystostomy in the treatment of acute cholecystitis during pregnancy

The purpose of this study was to investigate the efficacy of precutaneous cholecystostomy (PC) in treatment of acute cholecystitis during pregnancy. The author retrospectively evaluated six pregnant patients who underwent PC for acute cholecystitis between 1994 and 2014. The median age of the patients were 31 years (22-36). Two patients were in first trimester and the others in third trimester. All patients were underwent medical therapy before PC; since no improvement was observed in their complaints and physical examination findings, the author performed PC. All patients underwent LC following PC. PC is a safe, alternative treatment modality for palliative purposes in pregnant patients with acute cholecystitis who are unresponsive to medical therapy or who have comorbid conditions making surgery risky, or in acute cholecystitis cases occurring in third trimester of pregnancy to reach postpartum period when surgery is safer.

Intraperitoneal Administration of Low Dose Aluminium in The Rat: How Good is It to Produce a Model for Alzheimer Disease

Since neurotoxicity of aluminium (Al) resembles the progressive neurodegeneration observed in Alzheimer Disease (AD), Al administration in several ways has been used to produce AD model. Intraperitoneal (ip) low dose (4.2 mg/ kg) Al injection in rats for long periods is the preferred method by some researchers. In this paper, the efficiency of this method for producing an AD model was evaluated. In this study, we looked at the neuropathology of Al and the characteristic lesions of AD by histological and immunohistochemical techniques and determined oxidative stress markers in the brains of Al-treated and control rats. We also made electrophysiological recordings at the hippocampus and evaluated possible behavioural changes by Morris water maze test. However, no pathologic changes occurred in the animals except for an impairment in long-term potentiation (LTP) in the hippocampus (e.g. the LTPs of population spike (PS) amplitude at 15 min post-tetanus were measured as 217±27% in Al-treated rats and as 240±42% in sham-treated rats, of baseline PS amplitude). According to the findings of the present study, low dose of ip Al in rats is not sufficient to produce a good AD model. Higher doses (≥10 mg/kg) should be used.

Results of surgical treatment of anterior abdominal wall desmoid tumours : 13 cases reviewed with literature

BACKGROUND

We retrospectively evaluated the results of surgical treatment for anterior abdominal wall -desmoid tumours.

METHODS

Records for 13 patients operated on for desmoid tumours from 1997-2013 were searched for age, gender, abdominal/pelvic surgical history, pregnancy, Gardner's syndrome, pre-operative radiological examinations, tumour size, multifocality, surgical procedure, tumour presence at surgical margins, recurrence, morbidity, and mortality. Local recurrence-free survival probabilities were estimated by the Kaplan-Meier method and stratified by various clinicopathological variables.

RESULTS

There were 11 female (84,6%) and 2 male (15,4%) patients with a median age of 36 years. Seven (53,8%) -patients had previous abdominal/pelvic surgery, five (38,5%) had a history of pregnancy, and one (7,6%) had Gardner's Syndrome. Two (15,3%) patients had multifocality on their pre-operative radiological examinations. Mean tumour -diameter was 4,6 cm (SD 3,2 cm ; range 2-12 cm). After the excision of the masses in five (38,5%) patients, synthetic materials were used to close the abdominal wall defects. Two (15,3%) patients with positive surgical margins after -surgery were re-operated. Three (23%) patients required a second surgical intervention after the mass excisions were performed. Mean follow-up time was 56,7 months. Recurrence was observed in three patients during follow-up. Increased tumour size, history of previous abdominal/pelvic surgery, and the presence of multifocality had a negative effect on local recurrence-free survival. There was no mortality during follow-up.

CONCLUSIONS

Desmoid tumours are characterized by high recurrence, even after proper surgical excisions. Preoperative differential diagnoses of these tumours should be done and a post-operative follow-up protocol should be followed.

Preventing LVAD implantation by early short-term mechanical support and prolonged inodilator therapy : A case series with acute refractory cardiogenic shock treated with veno-arterial extracorporeal membrane oxygenation and optimised medical strategy

Cardiogenic shock continues to be a life-threatening condition carrying a high mortality and morbidity, where the prognosis remains poor despite intensive modern treatment modalities. In recent years, mainly technical improvements have led to a more widespread use of short- and long-term mechanical circulatory support, such as veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and left ventricular assist devices (LVADs). Currently, LVADs are indispensable as 'bridge' to cardiac recovery, heart transplantation (HTX), and/or as destination therapy Importantly, both LVADs and HTX put a vast burden on financial resources, besides significant short- and long-term risks of morbidity and mortality. These considerations underscore the importance of optimal timing and appropriate patient selection for LVAD therapy, avoiding as much as possible an unfortunate and costly clinical path. In this report, we present a series of three cases with acute refractory cardiogenic shock ('crash and burn', INTERMACS profile 1) successfully treated by ECMO and early optimal medical therapy preventing a certain path towards LVAD and/or HTX, for which they were initially referred. This conservative approach in INTERMACS profile one patients warrants very early introduction of adequate medical heart failure therapy under the umbrella of a combination of short-term mechanical circulatory and inotropic support by phosphodiesterase inhibitors. Therefore, this novel combined medical-mechanical approach could have important clinical implications for this extremely challenging patient category, as it may avoid an unnecessary and costly clinical path towards LVAD and/or heart transplantation.

Emergent surgical treatment of radiation-induced enteropathies for patients with urogynecological and colorectal carcinomas

AIM

The aim of this study is to describe our 10-year experience in patients with urogynecological and colorectal carcinomas with radiation enteropathy treated surgically as an emergency, and to reassess symptoms and mortality.

PATIENTS AND METHODS

The study included 17 patients receiving emergency surgery for complications of radiotherapy. Data about the patients and outcomes of the treatment alternatives used were retrospectively analyzed.

RESULTS

Of 17 patients, nine had colorectal cancer, six had gynecological cancer, and two had cancer of the urinary system. As an emergency, 12 patients had ileus only, one patient had intestinal fistulae and ileus, two patients had bleeding and ileus and two patients had perforation on admission. Seven patients underwent resection and anastomosis, two patients intestinal by-pass, four patients resection and ostomy and four patients bridectomy. Morbidity (75% for early complications and 100% for late complications) and mortality in the early postoperative period (25%) were higher in the patients undergoing bridectomy than in the patients undergoing other surgical methods. The rate of early and late complications (71.4% and 66.6%, respectively) was lower in the patients undergoing resection-anastomosis with a higher of quality life. Only 11 patients survived during a long follow-up period (64.7%).

CONCLUSION

As the postoperative complication rate, overall and operative mortality of patients treated for radiation enteropaties as emergent surgery are high, specialists following this group of patients may favor removal of the pathologic tissue to avoid complications in the early and late postoperative period.

Paradoxical effects of interatrial conduction delay in a hypertrophic cardiomyopathy patient in the long-term: time is a great healer

We present a unique case where early proarrhythmic and late antiarrhythmic characteristics of interatrial conduction delay were observed during the long-term progression of HCM. Occurrence of AT constantly increased as the interatrial conduction delay became more prominent, while the P-wave width in sinus rhythm and the AT cycle length both showed an instantaneous increase in parallel. As the interatrial delay reached a critical point, the right and left atrial P-wave became virtually separated, as demonstrated by the findings of ECGs and echocardiography. This phenomenon resulted in the complete cessation of tachycardias.

Donor-specific immune regulation by CD8 lymphocytes expanded from rejecting human cardiac allografts

To assess whether regulatory T cells are present in rejecting human cardiac allografts, we performed functional analyses of graft lymphocytes (GLs) expanded from endomyocardial biopsies (EMB; n = 5) with histological signs of acute cellular rejection. The GL cultures were tested for their proliferative capacity and regulatory activity on allogeneic-stimulated peripheral blood mononuclear cells (PBMC) of the patient (ratio PBMC:GLs = 5:1). Three of these GL cultures were hyporesponsive to donor antigens and suppressed the antidonor proliferative T-cell response of PBMC, but not the anti-third-party response. Interestingly, it was the CD8(+) GL subset of these cultures that inhibited the antidonor response (65-91% inhibition of the proportion of proliferating cells); the CD4(+) GLs of the expanded GL cultures were not suppressive. In conclusion, CD8(+) GLs expanded from rejecting human cardiac allografts can exhibit donor-specific immune regulatory activities in vitro. We suggest that during acute cellular rejection, GLs may not only consist of graft-destructing effector T cells, but also of cells of the CD8(+) type with the potential to specifically inhibit antidonor immune reactivity.

Guidelines for heart transplantation

Based on the changes in the field of heart transplantation and the treatment and prognosis of patients with heart failure, these updated guidelines were composed by a committee under the supervision of both the Netherlands Society of Cardiology and the Netherlands Association for Cardiothoracic surgery (NVVC and NVT).THE INDICATION FOR HEART TRANSPLANTATION IS DEFINED AS: 'End-stage heart disease not remediable by more conservative measures'.CONTRAINDICATIONS ARE: irreversible pulmonary hypertension/elevated pulmonary vascular resistance; active systemic infection; active malignancy or history of malignancy with probability of recurrence; inability to comply with complex medical regimen; severe peripheral or cerebrovascular disease and irreversible dysfunction of another organ, including diseases that may limit prognosis after heart transplantation.Considering the difficulties in defining end-stage heart failure, estimating prognosis in the individual patient and the continuing evolution of available therapies, the present criteria are broadly defined. The final acceptance is done by the transplant team which has extensive knowledge of the treatment of patients with advanced heart failure on the one hand and thorough experience with heart transplantation and mechanical circulatory support on the other hand.

The adequacy of laparoscopy for continuous ambulatory peritoneal dialysis procedures

The aim of this study was to determine the safety and efficacy of diagnostic/therapeutic laparoscopy in the management of peritoneal Tenchoff catheter placement in end-stage renal disease patients who had previous abdominal surgery and malfunctioning peritoneal dialysis catheters. From 1999 to 2004, 16 videolaparoscopic procedures were performed in 16 patients who had previous laparotomies. Laparoscopy was performed before peritoneal catheter placement in seven (group 1) and in 9 patients with peritoneal dialysis catheters in place, laparoscopy was performed for the management of catheter dysfunction (group 2). All laparoscopic procedures were performed under general anesthesia. The mean follow-up was 31.5 (range, 11 to 60) months. In group 1, six patients (85.7%), and in group 2, seven patients (77.7%) are still on peritoneal dialysis. Laparoscopy resulted in the placement/salvage of peritoneal dialysis catheter dysfunction. Placement of catheter was accomplished in patients who would have been previously designated as unsuitable candidates. Laparoscopy is a useful tool in every step of a peritoneal dialysis program.

FoxP3+ T Cells Can Be Expanded From Rejecting Cardiac Allografts

A specific subset of T cells, the FoxP3+ regulatory T cells, control effector T-cell responses to self and foreign antigens. In transplant patients, we and others have shown that high intragraft FOXP3 mRNA levels are associated with acute rejection, suggesting that immune regulation is dependent on immune activation. To study whether transplanted grafts harbor FoxP3+ T cells and to functionally analyze them, graft infiltrating lymphocytes (GILs) must be propagated from the transplanted tissue. In the present study, we analyzed whether FoxP3+ T cells can be grown from endomyocardial biopsies (EMBs; n = 5) from patients after heart transplantation during acute cellular rejection. After 18 to 21 days of culture, 0.5 to 1.0 x 10(6) GILs were cultured from the EMBs. Of these GILs, 10.6% (median; range, 1.6%-17.1%) stained positive for FoxP3. Thus Foxp3+ T cells can be grown from EMBs, providing the tools to functionally characterize these cells in depth in forthcoming studies.

An Unusual Case of Port Site Metastasis After Laparoscopic Cholecystectomy in a Renal Transplant Patient: A Case Report

Port site metastasis after laparoscopy is a rarely seen intraabdominal malignancy independent of tumor stage. We present an unusual case of port site adenocarcinoma metastasis from unknown origin following laparoscopic cholecystectomy. A 52-year-old woman with a previous renal transplant underwent a laparoscopic cholecystectomy for symptomatic cholelithiasis. Six months later, she was admitted to the hospital with a complaint of a mass at the four trocar sites. A biopsy from the port sites led to the diagnosis of adenocarcinoma metastasis. Port site metastasis after laparoscopic cholecystectomy is seen especially after gallbladder cancer, and less frequently after intraabdominal malignancy independent of tumor stage. Our patient illustrated that port site metastasis probably spread from an undetected cancer site of an early stage intraabdominal tumor. Immunosuppression may have increased the likelihood of tumor seeding at the port sites.

Hydrodissection with adrenaline–lidocaine–saline solution in laparoscopic cholecystectomy

AIM

This investigation examined the effects of a solution injected to the gallbladder bed on operative time, bleeding, incidence of gallbladder perforation, and postoperative pain.

METHODS

One hundred sixty-four consecutive patients with cholelithiasis were randomized into two clinically comparable groups. In group 1 (84 patients), 40 ml of saline-adrenaline-lidocaine solution was injected between the gallbladder and liver. In group 2 (80 patients), laparoscopic cholecystectomy was performed without hydrodissection. The time taken to dissect the gallbladder from the liver, bleeding from the liver bed, incidence of gallbladder perforation and spillage of bile and stones, duration of operation, amount of gas used for the laparoscopic cholecystectomy, conversion to open cholecystectomy, postoperative pain and pain localization were recorded.

RESULTS

The mean dissection time, amount of gas used, incidence of gallbladder perforation, spillage of stones, and liver bed bleeding were not significantly different between the groups. There also was no significant difference between the groups regarding postoperative pain and pain localization.

CONCLUSION

Hydrodissection did not reduce time to dissect the gallbladder from the liver or risk of gallbladder perforation. Similarly, adrenaline and lidocaine injection between the gallbladder and the liver did not effect bleeding from the dissection area and did not alter postoperative pain or pain localization.

Wide spectrum of presentation and variable outcomes of isolated left ventricular non-compaction

OBJECTIVES

To investigate diagnostic routes, echocardiographic substrates, outcomes and prognostic factors in patients with isolated ventricular non-compaction (IVNC) identified by echocardiographic laboratories with referral from specialists and primary care physicians.

PATIENTS AND DESIGN

Since 1991, all patients with suspected IVNC were flagged and followed up on dedicated databases. Patients were divided into symptom-based and non-symptom-based diagnostic subgroups.

RESULTS

65 eligible patients were followed up for 6-193 months (mean 46 (SD 44). In 53 (82%) patients, IVNC was associated with variable degrees of left ventricular (LV) dilatation and hypokinesia, and in the remaining 12 (18%) LV volumes were normal. Diagnosis was symptom based in 48 (74%) and non-symptom based in 17 (26%) (familial referral in 10). The non-symptom-based subgroup was characterised by younger age, lower prevalence of ECG abnormalities, better systolic function and lower left atrial size, whereas the extent of non-compaction was not different. No major cardiovascular events occurred in the non-symptom-based group, whereas 15 of 48 (31%) symptomatically diagnosed patients experienced cardiovascular death or heart transplantation (p = 0.01, Kaplan-Meier analysis). Independent predictors of cardiovascular death or heart transplantation were New York Heart Association class III-IV, sustained ventricular arrhythmias and left atrial size.

CONCLUSIONS

IVNC is associated with a broad spectrum of clinical and pathophysiological findings, and the overall natural history and prognosis may be better than previously thought. Adult patients with incidental or familial discovery of IVNC have an encouraging outlook, whereas those who have symptoms of heart failure, a history of sustained ventricular tachycardia or an enlarged left atrium have an unstable course and more severe prognosis.

Brachial artery pseudoaneurysm: a rare complication after haemodialysis therapy

Haemodialysis patients carry a high risk of pseudoaneurysm due to inadvertent puncture of the brachial artery during venous cannulation for haemodialysis. Signs and symptoms are pulsatile mass and a systolic murmur. Complications are rupture, infection, haemorrhage, distal arterial insufficiency, venous thrombosis and neuropathy. Early diagnosis is essential to plan adequate treatment. Doppler US and angiography usually confirm the lesion accurately. Ultrasound guided compression, percutaneous injection of thrombin, endovascular covered stent exclusion, aneurysmectomy and surgical repair are different treatment options. We report clinical and radiological findings and treatment strategies in four dialysed patients who developed brachial artery pseudoaneurysms.

Burns in Southern Turkey: Electrical Burns Remain a Major Problem

In Turkey, burns represent a relatively small number of injuries overall, but they continue to be a major public health problem. Our aim in this study was to identify risk factors that affect outcome in burn patients hospitalized in the southern part of our country, with special emphasis on electrical burns. The database for 109 burn patients who were admitted to our burn center from April, 2000, through August, 2001, was retrospectively analyzed. Electrical injury was the cause of burn in 23 (21%) of the 109 cases. The burn causes differed among age groups and between the sexes, with males constituting 95% of the electrical burn patients. The mortality rate for the electrical burn group was lower than the rate for the rest of the burn patients (1/23 vs 17/86, respectively; P <.001); however, the opposite was true for complication rate (10/23 vs 5/86, respectively; P <.001), cost of treatment (8351 US dollars vs 5122 US dollars, respectively; P =.009), and length of hospital stay (39.9 vs 26.2 days, respectively; P < 0.001). The rate of electrical burn injury in Turkey has changed very little in the past two decades. This underlines the need for stronger efforts aimed at prevention, such as better public education and strict regulations regarding the distribution and use of electricity.
