ABSTRACT

A total of 508 fish specimens belonging to 19 species collected in the coast of Sile region of the Black sea were examined to detect the presence of endohelminths. Of this, 357 (70.27%) were found to be infected with parasites. 15 distinct helminths species were recovered including four species of nematodes, seven digenean species, one species of cestodes and three species of acanthocephalans. It was also determined that the species of nematode Hysterothylacium aduncum was the most common parasite and the most diverse endohelminth fauna was found in Gobius niger and Solea vulgaris, with five species. Furthermore, it should be noted that Capillaria gracilis is reported for the first time from the Turkish coasts. The infection rates, hosts, and parasites are listed in this paper.

ABSTRACT

Systemic pseudohypoaldosteronism (PHA) is a rare, salt-wasting syndrome that is caused by inactivating variants in genes encoding epithelial sodium channel subunits. Hyponatremia, hyperkalemia, metabolic acidosis, increased aldosterone and renin levels are expected findings in PHA. Clinical management is challenging due to high dose oral replacement therapy. Furthermore, patients with systemic PHA require life-long therapy. Here we report a patient with systemic PHA due to SCNN1B variant whose hyponatremia and hyperkalemia was detected at the 24th hour of life. Hyperkalemia did not improve with conventional treatments and dialysis was required. He also developed myocarditis and hypertension in follow-up. Challenges for diagnosis and treatment in this patient are discussed herein. In addition, published evidence concerning common features of patients with SCNN1B variant are reviewed.

ABSTRACT

Social contact between individuals is believed to be a fundamental cause in the transmission of many respiratory tract infections. Because they have not yet been fully vaccinated, infants are at high risk for contracting whooping cough, influenza and their serious complications. Therefore, determining infant social contact patterns is an important step in protecting them from respiratory tract infection. This study included 1200 healthy infants (<12 months of age). Social contact diaries were used to estimate the frequency and nature of the infants' social contacts. This survey also gathered information regarding the infants' respiratory symptoms and their frequency of attendance at crowded places over a period of 1 week. The diary return rate was 83.8% (N = 1006), and there was a total of 4706 contacts reported for these infants. The median daily contact number per capita was 4 (range 1-18). The median number of contacts with adolescents was 0 (range 0-7). Of the infants, 50.3% had contact with non-household individuals. The mothers had the longest contacts with their babies. Contacts with school children, frequency of attendance at crowded places and age were determined to be significant effective factors for reporting respiratory symptoms. Results suggest that school-age siblings and the mothers should be primarily vaccinated, and parents should keep their babies away from crowded places for protecting their infants.

ABSTRACT

Glycogen storage disease type I (GSD-I) is a group of autosomal recessive disorders that include types Ia and Ib. GSD-Ib is caused by a deficiency in the glucose-6-phosphate transporter (G6PT) caused by a mutation in the SLC37A4 gene coding for G6PT. Glycogen storage disease is characterized by poor tolerance to fasting, growth retardation and hepatomegaly resulting from accumulation of glycogen and fat in the liver and chronic neutropenia. Herein we describe a 4-month-old Turkish patient with early onset and severe typical clinical features of GSD-1b in which a novel mutation in the SLC37A4 gene was detected. After the bone marrow examination parenteral antibiotic therapy and subcutaneous granulocyte colony-stimulating factor (G-CSF) were started. Due to the severe neutropenia the patient had developed nosocomial sepsis and the dose of G-CSF was increased. After 2 months later from the initial treatment of the G-CSF he developed splenomegaly and urinary complications. Despite maximal therapy he had an extremely poor quality of life and life-threatening complications due to impaired bone marrow function. As the patient required continual hospitalization he was schedule for bone marrow transplantation.

ABSTRACT

Paracanthocephaloides kostylewi (Meyer, 1932), a rare parasite of the common sole Solea solea, previously placed in the Arhythmacanthidae, is transfered to the genus Solearhynchus de Buron & Maillard, 1985 of the family Echinorhynchidae as Solearhynchus kostylewi (Meyer, 1932) new comb., because its proboscis is armed by a single type of hooks, the posterior hook in each row is pinlike and with feebly developed root. The species is redescribed on the basis of newly collected material from the Gemlik Bay, Sea of Marmara. A key to the species of Solearhynchus is provided.

ABSTRACT

BACKGROUND AND OBJECTIVES: The study aimed to evaluate the utility of a laparoscopic approach in the management of patients with right lower abdominal pain and in the quality of life after the operation. METHODS: Patients with suspected appendicitis were included in the study. They were randomly assigned either to treatment with a traditional open approach or with a laparoscopic approach. The patients' data, including demographic data, complications and gastro-intestinal quality of life index scores, were collected at the 6th week and 6th month and compared between the groups. RESULTS: Overall, 83 appendectomies were performed. Other pathologies were ovulation bleeding, ovarian cyst, Meckel's diverticulum, ectopic pregnancy and leiomyoma of the uterus. Negative appendectomy rate was 7%. Severe infection occurred in five of the open group. The advantages of the laparoscopy also showed significantly in hospital stay (55.80 +/- 20.97 hours vs. 75.06 +/- 35.14 hours), the need for narcotics and in visual analog score, as well as in the gastrointestinal quality of life index (85.88 +/- 9.73 vs 101.30 +/- 9.31). The quality of life is still better in the long-term (95.14 +/- 8.45 vs 120.36 +/- 10.25). When the groups were compared according to the subgroups of gastro-intestinal quality of life index, except for disease-specific items, in all categories a significant improvement was seen in the laparoscopically treated patients. This improvement was observed in the follow-up period also. However, the hospital costs (987.50 +/- 77.25 USD vs. 406.27 +/- 100.59 USD) and operative time (56.25 +/- 10.9 vs. 49.41 +/- 11.76 minutes) still continued to be a problem for the laparoscopic group. CONCLUSION: Laparoscopic appendectomy is a safe method, which also has advantages of diagnostic procedure for other pathologies, a better quality of life both in the early and late period, and a short hospital stay. The important advantage is also seen in the late period with better quality of life.

ABSTRACT

Complete resection of liver metastasis may provide long term survival in patients with colorectal cancer. Increased number of studies on successful resection after neoadjuvant chemotherapy with initially unresectable liver metastasis has been reported. We evaluated retrospectively the results of 35 patients with unresectable liver only metastases from colorectal cancer treated with capecitabine plus oxaliplatin combination (XELOX). Treatment consisted of IV oxaliplatin 130 mg/m2 day 1 and oral capecitabine 1000 mg/m2 day twice daily on days 1 to 14 followed by 7 days of rest repeated every 3 weeks. After chemotherapy, 13 (37, 2 %) patients showed partial clinical response. Among them, 7 patients were considered suitable for surgery but 2 patients refused the surgery. While one of 5 patients had unresectable disease at surgery, the remaining 4 patients (11, 4 %) had a complete resection. There was one postoperative mortality due to sepsis within 2 months after surgery. Our data suggests that XELOX regimen seems to be useful in unresectable liver only metastases from colorectal cancer because of its activity, feasibility and tolerability. Further studies of XELOX in combination with bevacizumab and/ or cetuximab are warranted in this setting.

ABSTRACT

Hemangiopericytoma is a rare, vascular soft tissue tumour originating from the pericytes, the contractile cells that surround capillaries. A case of retrorectal hemangiopericytoma in a 49-year-old woman is reported. With a posterior sagittal approach, the tumour was completely removed. Pathological examination, including immunohistological stains, was consistent with a hemangiopericytoma. A step-by-step approach to a retrorectal tumour is exemplified, and a very rare pathological entity is added to the spectrum of retrorectal masses.

ABSTRACT

OBJECTIVE: To investigate the effect of l-alanine-l-glutamine (Gln) on postoperative complication rate and duration of hospitalization in patients operated for colorectal cancer. METHOD: A total of 109 patients operated with the diagnosis of colorectal cancer and given enteral nutrition between January 2001 and January 2005 were prospectively analysed. The patients were randomized and analysed in two groups; Gln group (n = 57): patients were given parenteral Gln (1 g/kg/day, Dipeptiven, Fresenuis Kabi, Germany) together with enteral nutrition (Ensure; Abbott, Zwolle, The Netherlands) and the control group (n = 52) only received enteral nutrition (Ensure; Abbott), which was a standard isonitrogenous and isocaloric formula. The supplemental enteral nutrition was provided for at least 5 days pre- and postoperatively according to the nutritional status of the patients. Age, gender, subjective global assessment (SGA), body mass index (BMI), serum albumin, protein, associated disorders, localization of pathology, techniques of anastomosis, postoperative complications and length of hospital stay were analysed for each patient. RESULTS: The duration of nutritional support in the Gln group was 6 +/- 2 and 5 +/- 1 days pre- and postoperatively; while it was 7 +/- 1 and 6 +/- 1 days for the control group, and there were no significant difference among the groups (P > 0.05). Age, gender, SGA, BMI, levels of serum albumin and protein, localization of pathology and techniques of anastomosis were also similar (P > 0.05). Wound infection (P = 0.038), intraabdominal abcess formation (P = 0.044) and wound dehiscence (P = 0.044) were significantly higher in the control group than in the Gln group. There was no significant difference in terms of anastomotic leakage and other complications between both groups (P > 0.05). Hospital stay was significantly shorter in the Gln group (P < 0.001). CONCLUSION: Supplementation of parenteral Gln decreased the postoperative complications and hospital stay and in the patients undergoing the colorectal surgery for cancer.

ABSTRACT

OBJECTIVE: This study was conducted to determine the indications for and outcome of colorectal intervention in patients with advanced gynaecological malignancy. METHODS: Between January 1999 and June 2004, 27 gynaecological cancer patients underwent 36 colorectal intervention performed by general surgeons. The 36 operations were associated with 14 (39%) primary surgical procedures, 9 (25%) second-look laparotomies, and 13 (36%) procedures for recurrence or palliation. RESULTS: The mean age was 56 years (range 32-83 years). The majority of operations were performed in patients with ovarian (67%), endometrial (18%) and cervical (15%) malignancy. The primary indications for colorectal resection was tumour cytoreduction in 56% of the 36 operations. Other indications included repair of iatrogenic bowel injuries (n = 9, 25%), resection for multiple iatrogenic enterotomies (n = 4, 11%), and bowel obstruction (n = 3, 8%). The most frequently performed bowel operation was rectosigmoid resection with end-to-end anastomosis (n = 19, 53%). Colostomy was performed in 14% of the rectosigmoid resections at primary surgery. Small-bowel resection was required in 31% of the 36 operations. Postoperative complications included wound complications (14%), pulmonary infections (8%), cardiac complications (6%) and intra-abdominal abscess (6%). There was a single surgical mortality (3%). CONCLUSION: Colorectal intervention is frequently indicated during operations for advanced gynaecological malignancy, and they are associated with a significant rate of postoperative complications. Specialists operating on gynaecological malignancy should have the technical skills necessary to perform these procedures.

ABSTRACT

Regular aerobic exercise improves aerobic capacity and increases brain blood flow and oxygenation. Exercise also stimulates the reticular activating system and leads to a centrally excited state thereby makes the brain active and alert. In the present study, an aerobic exercise program consisting of submaximal level calisthenic exercises was devised for relatively healthy women between 60 and 80 years old, attending a solidarity center for the aged for daily activities. The effects of exercise on aerobic fitness, and the correlations between aerobic capacities, pulmonary functions and cognition were evaluated. Following a general health examination, 45 female volunteers fulfilling the international criteria of exercising standards for the aged were included in the program. The rhythmic and entertaining calisthenic exercises were performed by the older women for four months, three days a week, 40 or 50 minutes a day. Tests for aerobic capacities, pulmonary functions, and some neuropsychologic performances were carried out during the sedentary period and after the exercise program. The results revealed significant improvements in aerobic capacity, pulmonary functions, and some of the cognitive functions after the 4-month exercise program. We found strong relationships between aerobic capacities and cognitive functioning. Overall, the subjects expressed their happiness and well being on every occasion, during and after the exercise program.

ABSTRACT

We examined the cytogenetic and genotoxic effects of the neonicotinoid insecticide imidacloprid and the organophosphate insecticide methamidophos, when administered alone or in combination. These insecticides were tested with the bone marrow chromosome aberration assay and micronucleus test in rats and by the bacterial mutation assay (Salmonella/microsome mutagenicity assay). Wistar albino rats were orally fed daily with laboratory chow treated with various concentrations of insecticides, 50 and 100 mg/kg imidacloprid, 2.5 and 5 mg/kg methamidophos, and 2.5 and 5 mg/kg imidacloprid plus methamidophos, respectively, for 90 days. Numerical and structural chromosomal aberrations were evaluated. Significant differences were detected between all the insecticide-administered groups versus the control group and between the two concentrations of the pesticide-treated groups. Both concentrations of the insecticides induced a dose-related increase in the micronucleus frequency (P < 0.05). Dose-related increases in the number of revertants were observed with the two Salmonella strains (TA98 and TA100). All tested doses of the insecticides demonstrated mutagenic activity in the presence of S9 mix. These results lead us to the conclusion that the synergistic effect of methamidophos and imidacloprid causes an increase in potential damage to non-target organisms.

ABSTRACT

Some cases of idiopathic pruritus anu may be refractory to treatment with dietary and hygienic instructions and short-term topical medications. In this study, we documented our technique and results with methylene blue injection in a large series of patients with intractable idiopathic pruritus ani. The results of 30 adult patients with well-documented intractable idiopathic pruritus ani who were treated with intradermal methylene blue injection are reported. No antibiotic prophylaxis, anesthesia or sedation was used. A total of 15 ml of a 1% methylene blue solution was injected intracutaneously and subcutaneously in the affected perianal area. A second injection (rescue treatment) was offered one month later to patients who declared partial response, and follow-up was restarted. One month after injection, 24 patients (80%) were symptom-free, 5 declared partial remissions, and one patient still had the same degree of pruritus ani. Five patients with partial remission underwent a second methylene blue injection, which provided complete relief in four. Therefore, the early response rate was 80% with single injection and 93.3% (28 of 30) with the rescue treatment. At six months, three recurrences were noted, indicating to a success rate of 83.3% (25 of 30). At 12 months after treatment, 23 patients (76.7%) were symptom free. This study has shown that intradermal methylene blue injection is a safe, simple, fast and efficient method of treating intractable idiopathic pruritus ani.

ABSTRACT

We aimed to clarify the effects of different enteral nutrients (normal chow, complete balanced nutrition, elemental nutrition enriched with glutamine, immune-enhancing diet and fiber) on colonic anastomotic healing in the stress-free metabolic state. The study was carried out with 50 male Balb-C mice in five groups of 10 animals each. After transverse colon anastomosis, animals were fed with early enteral nutrients using normal chow (group 1), Ensure((R)) (group 2), Alitraq((R)) (group 3), Impact((R)) (group 4), and Benefiber Resource((R)) orange juice drink (group 5) for 7 days. There were no significant differences among the groups in bursting pressure (p > 0.05). There was no statistical difference in terms of hydroxyproline level among groups 1-3. The hydroxyproline levels of groups 4 and 5 were statistically higher than that of the control group (p < 0.05 for both comparisons). Under normal conditions without stress, we could not demonstrate the superior effects of early enteral feeding with specialized enteral preparations over normal diets on colonic anastomoses when the bursting pressures were compared.

ABSTRACT

BACKGROUND: The management of high and complicated anal fistulas remains a therapeutic challenge, and the oldest and theoretically the simplest technique is to use a seton. In this article, we document our recent experience in managing high anal fistulas with a simple modification of the cutting seton. PATIENTS AND METHODS: Surgical outcomes of patients treated by the elastic cutting seton for anal fistulas that involved more than half of the sphincter muscles or for anterior trans-sphincteric fistulas in female patients were analyzed. The elastic seton, which was created by cutting a thin (2-3 mm) circular strip from a surgical glove, including its thicker sleeve, was inserted through the remaining tract in a double-strand fashion, and then tied on the sphincter with two knots in a slightly tight manner. RESULTS: Complete healing was achieved in 9 cases (45%) at 1 month and in all cases (100%) at 3 months postoperatively. Recurrent fistula was noted in a single patient (5%) at 8 months. Worsening of preoperative continence was noted in 4 patients (20%). However, the postoperative incontinence score (0.70+/-1.22) did not differ significantly from the preoperative score (0.41+/-0.41; p=0.059, Wilcoxon's test). CONCLUSIONS: The preliminary results of this series suggest that the elastic cutting seton may be a valid alternative for the treatment of high anal fistulas. The possible positive contribution of the slow and stable cutting of the sphincter on the maintenance of continence is further supported. An important practical disadvantage of the conventional seton treatment, namely the need for postoperative adjustments, is also eliminated.

ABSTRACT

PURPOSE: To review the distribution of intrahepatic portal venous branching in order to determine the prevalence of variations. MATERIAL AND METHODS: We made a retrospective review of 655 contrast-enhanced helical CT (CECT) images of patients referred to our department for upper abdominal CT examination during an 8-month period. Of the 655 patients, 70 were eliminated from the study because of improper opacification of the portal venous system. Variations of portal venous branching in the remaining 585 patients were classified. RESULTS: Of 585 patients, 504 (86.2%) had classical bifurcation of the main portal vein (MPV); 72 (12.3%) had a trifurcation of the MPV, 5 (0.9%) had a right anterior segmental branch originating from the left portal vein (LPV), 2 (0.3%) had an LPV originating from the right anterior segmental branch and 2 (0.3%) had a right posterior segmental branch arising from the MPV. CONCLUSION: Variations of portal venous branching are common and helical CT is efficacious in identifying these variations.

ABSTRACT

Even with excellent operative techniques, prolonged ischemic periods may cause unwanted results because of a complex mechanism called reperfusion injury. Various pharmacological and immunological agents have been used to prevent this type of injury. Another known way to diminish reperfusion injury is the gradual reperfusion of the ischemic tissues. In this study, the effect of a gradual increase in blood flow on ischemia-reperfusion injury of the skeletal muscle was investigated. The right hind limbs of 15 rats were partially amputated, leaving the femoral vessels intact. Preischemic femoral arterial blood flow was measured by using a transonic small-animal blood flowmeter (T106) in all animals. The rats were divided into three groups: Group I consisted of control rats; no ischemia was induced. Group II was the conventional clamp release group. Clamps were applied to the femoral vessels to induce 150 minutes of ischemia. The clamps were then released immediately and postischemic blood flow was measured. Group III was the gradual clamp release group. After 150 minutes of ischemia, clamps were released gradually at a rate so that the blood flow velocity would reach one fourth the mean preischemic value at 30 seconds, one half at 60 seconds, three fourths at 90 seconds, and would reach its preischemic value at 120 seconds. Total clamp release was allowed when blood flow was less than 1.5 fold of the preischemic values. Postoperatively the soleus muscles were evaluated histopathologically, and malonyldialdehyde and myeloperoxidase levels were measured. The mean preischemic blood flow was 13.6 +/- 2.24 ml per kilogram per minute in all groups. In the conventional release group, postischemic flow reached four to five fold its preischemic values (61.06 ml per kilogram per minute). Histopathology revealed more tissue damage in the conventional release group. Malondialdehyde and myeloperoxidase levels were also significantly lower in the gradual release group. Depending on histological and biochemical findings, a gradual increase in blood flow was demonstrated to reduce the intensity of ischemia-reperfusion injury in the soleus muscle of this animal model.

ABSTRACT

The aim of the present study was to assess and to compare the orbital and retinal vascular flow dynamics and resistance in patients with homozygous sickle cell disease with controls by means of duplex and color Doppler ultrasonography. Forty-six patients with homozygous sickle cell disease (SCD) and 20 healthy subjects were included in the study. None of the patients had objective signs of ocular involvement. Duplex and color Doppler ultrasonography of the ophthalmic, short posterior ciliary, and central retinal arterial flows of the both eyes were performed to assess peak systolic flow velocity (PSFV), end-diastolic flow velocity (EDFV), and mean flow velocity (MFV) through entire cardiac cycle with further calculation of resistive indices (RI) and pulsatility indices (PI). Ophthalmic arterial flow velocities were significantly increased in patients with SCD than in controls (P < 0.0001). Blood flow velocities of the central retinal artery were found to be significantly reduced (P < 0.0001) while RI and PI values were markedly higher (P < 0.02 and P < 0.03) in patients with SCD compared to controls. Reduction of retinal vascular flow velocities and increase of retinal vascular resistance were significantly related to the mean hemoglobin and hematocrit levels, red blood cell count, and mean corpuscular hemoglobin volume (P < 0.009, P < 0.01, P < 0.02, and P < 0.04, respectively). In conclusion, Doppler ultrasonography in patients with SCD who had no objective signs of ocular involvement allowed detection enhancement of ophthalmic flow velocities, reduced retinal flow velocities, and increased retinal vascular resistance, which are associated with haematological features.

ABSTRACT

BACKGROUND/AIM: Colorectal cancer is seen mostly among patients older than 50 years of age. An aggressive behavior is a frequently cited as characteristic of colorectal cancer in young patients. The purpose of the present study was to reveal the clinicopathologic characteristics of colorectal cancer among patients under 50 years of age. METHODS: Two hundred and seventy-one patients with colorectal cancer admitted to our oncology center were evaluated, and clinicopathologic findings of the young and old patients were compared. Patient gender, site distribution, tumor stage classification, lymph node involvement, metastatic site, histologic classification, histologic differentiation, family history of malignant tumors, presenting symptoms and survival rates were compared. RESULTS: One hundred patients were 50 years of age or under. Clinical, histopathologic characteristics and overall survival of the two groups did not differ. A higher rate of familial cancer syndromes was detected among young patients. CONCLUSIONS: The presentation and outcome of the disease in young patients do not differ from those of older patients. A significant family history of colorectal cancer in the young patients showed the need for screening whereas the outcome of metastatic disease was poor. In order to anticipate long survival, early detection and aggressive treatment is necessary.
