RESUMO

Radiotherapy for head and neck carcinoma (HNC) has both curative and palliative purposes. This study investigated mouthrinse aMMP-8 levels, molecular forms of MMP-8, blood neutrophil counts and neurophil/lymphocyte ratios before and 3 weeks after HNC radiotherapy started. Thirteen HNC patients undergoing radiotherapy were included. Mouthrinse samples (before and 3 weeks after HNC radiotherapy had started) were assayed quantitatively by aMMP-8 point-of-care-kit (PerioSafe®/ORALyzer®) and by western immunoblot. Total neutrophil counts and neutrophil/lymphocyte ratios were evaluated in the hemogram results. Three weeks after HNC radiotherapy started, significant increases in aMMP-8 levels and neutrophil/lymphocyte ratios were observed. No significant difference was found in total neutrophil counts. Elevations of the activated and fragmented MMP-8 levels after HNC radiotherapy application were observed on western immunoblot analysis. The increase in the aMMP-8 levels and neutrophil/lymphocyte ratios indicate inflammation both locally and systemically suggesting increased risk for periodontitis due to the HNC radiotherapy.

RESUMO

Calcified fibrous tumor (CFT) is a rare benign tumor of mesenchymal origin. Between 1988 and 2019, a total of 272 CFT cases were reported. CFTs can be seen in all anatomical regions with soft tissue. Histologically, mononuclear inflammatory infiltrates and the presence of psammomatous calcification in dense hyalinized collagen are characteristic features of the tumor. Currently, if the tumor is located in only one focus, surgical removal is recommended. Although CFT is a benign tumor, it may cause complications. Diagnosis is often difficult due to the confusion of tumor findings with many diseases. We present a patient with CFT, whose omental lesions were detected on abdominal computed tomography, and the diagnosis was confirmed by histopathological examination.

RESUMO

It is known that some of the enzymes and substances secreted by 2nd and 3rd stages of the Lucilia sericata larvae to have bacteriostatic and bactericidal effects. From this point of view, we investigated the anti-leishmanial effect of larval secretions of the L. sericata on the Leishmania tropica both in vitro and in vivo conditions. In vitro: It was observed that promastigotes of L. tropica had undergone lyzis within 1 min in the larval secretions of L. sericata. However, larval secretion was ineffective on the promastigotes within Novy-MacNeal-Nicolle (NNN) cultures and RPMI 1640 medium. In vivo: Seven groups of male Balb/C mice (6 study groups and 1 control group), each composed of eight weeks old 10 mice were formed. L. tropica promastigotes were injected subcutaneosly to the soles of the SG mice' feet. In study groups, cutaneous lesions were developed Limoncu et al., 1997 in 2 (20%) and 1 (10%) of the SG-1 and SG-2, respectively after 15 days. There were L. tropica in the smears prepared from the lesions and L. tropica was observed in the cultures. Cutaneous lesions were not developed in 8 (80%), 9 (90%) and 10 (100%) of the SG-I, SG-II and SG-III, respectively. There were no cutaneous lesions developed in the soles of the feet. There were no L. tropica in the smears prepared from the infected soles of the feet neither L. tropica was observed in the cultures. Larval secretions were given into the cutaneous lesions to the feet soles of the SG-IV, V and VI mice after 6 months. No healing was observed in the cutaneos lesions of 4 (40%), 5 (50%) and 1 (10%) of SG-IV, SG-V and SG-VI, after 6 months, respectively. There were L. tropica in the smears prepared from the lesions and L. tropica was observed in the cultures. On the other hand, the lesions of 6 (60%), 5 (50%) and 9 (90%) of SG-IV, SG-V and SG-VI were diminished in size and disappeared completely after 6 months. There were L. tropica observed in the smears prepared from the infected soles of the feet and no growth was observed in the cultures. In the smears prepared from the cutaneous lesions developed in the soles of the feet of the control group mice, L. tropica was visualized and observed in the cultures. A statistical significant difference was observed between study groups and control group (p<0.001). In our study we demonstrated for the first time that the secretions of the 2nd and 3rd stages sterile and pure larvae of L. sericata had effects on promastigotes of L. tropica in in vitro and very effective on amastigote forms in in vivo conditions.

RESUMO

With the advent of single-port laparoscopy, the spectrum of abdominal surgeries performed is widening. The retraction of the left lobe of the liver in the upper gastrointestinal procedures is a critical maneuver with its added possible complications. In our study, we used the Cerrahpasa retractor (trademark pending by E. Eyuboglu and T. Ipek) for the retraction of the left liver in 22 patients with a different concept other than using the suturing or silk lace techniques described in previous studies. In our technique, the potential of tearing the liver or other anatomical structures is minimal. We believe that, with the aid of our Cerrahpasa retractor, the problem of liver retraction is being solved by a simple and safe technique.

RESUMO

BACKGROUND/AIMS: Since its original description in 1956 by Rudolph Nissen, minor changes were made in technical details of Nissen fundoplication. After the introduction of laparoscopic fundoplication, in order to reduce the rate of complications, some technical modifications led to the development of 'floppy' Nissen fundoplication. METHODOLOGY: From August 1993 to August 2009, laparoscopic Nissen fundoplication was performed on 2100 patients, 17 of whom underwent classical and 2083 underwent floppy fundoplication. All the operations were performed by the same surgical team. Preoperative work-up included 24-h pH monitoring, esophagogastroduodenoscopy and barium cineradiography. Esophageal manometry was not performed due to the physical impossibility of this tool at our clinic. Key steps of the operation were dissection of the hepatogastric and Laimer's ligament, dissection and closure of the hiatus, and short, floppy Nissen fundoplication. Phrenoesophageal ligament was divided to obtain at least of 4cm of an abdominal esophagus. RESULTS: On the follow-up, dysphagia lasted for 1 month in 5.2% (110), between 1-3 months in 0.7% (16) and more than 3 months in 0.1% (3) of patients. Mortality was seen in 1 (0.05%) patient, and it was related to fatal pulmonary vein injury during perioperative bougienage. CONCLUSIONS: Laparoscopic floppy Nissen fundoplication seems to be a safe and feasible technique for surgical treatment of gastroesophageal reflux disease.

RESUMO

Isolated abdominal wall actinomycosis in the presence of an intrauterine contraceptive device (IUCD) is extremely rare and only six such cases have been reported in the literature. We report a case where clinical and radiological examinations revealed a pseudotumor within the anterior abdominal wall. After being lost to follow-up, the patient presented two years later with the enlargement of the mass. The mass including the affected anterior abdominal wall was completely excised. The diagnosis of actinomycosis was established postoperatively by histopathological examination. Further questioning concerning her gynecological history revealed long-term use of the same IUCD. Surgical excision of the actinomycotic pseudotumour and removal of the IUCD followed by antibiotic therapy resulted in the full recovery of the patient.

RESUMO

BACKGROUND: The division of the short gastric vessels (SGVs) is a common practice during laparoscopic floppy Nissen fundoplication (NF) to achieve an adequate mobilization of the gastric fundus. However, the terminal branches of splenic vessels can also be ligated during SGV division, resulting in splenic infarction (SI). The aim of this study was to evaluate our results with SI as a complication of laparoscopic floppy NF. MATERIALS AND METHODS: All patients with direct laparoscopic evidence of SI during laparoscopic floppy NF, between August 1993 and August 2009 and under the care of two surgeons, were included in this retrospective study. RESULTS: Over the past 16-year period, 2100 patients underwent laparoscopic floppy NF, and splenic infarction was demonstrated in 20 cases (0.95%). There were 11 women (55%) and 9 men (45%), with a mean age of 35.2 years (range, 25-68). The classic pattern, in all cases, was a small area of infarction, less than 10-15% of the total splenic volume, localized mainly in the upper pole. There were no conversions. The mean length of hospital stay was 1.2 days (range, 1-2). During the follow-up period of 3 months, only 2 patients (10%) had persistent abdominal pain, in which computed tomography demonstrated the infarcted areas involving less than 15% of the splenic parenchyma. All cases were managed succesfully with observation alone. CONCLUSIONS: Based on the results, partial SI is a recognizable condition during laparoscopic floppy NF. Conservative therapy and close follow-up, without any unnecessary intervention, is an appropriate management that provides a favorable outcome.

RESUMO

BACKGROUND: Incisional hernias develop in 2 to 20% of laparotomy incisions. Approximately 100,000 ventral hernias are operated on each year in the United States. The reported recurrence rates for open repair are 25-52% for primary and 12.5-19% for mesh repair. Compared to the open technique, laparoscopic repair has low rates of complications and recurrence, greater patient acceptance, and shorter hospital stay. MATERIALS AND METHODS: Between April 1999 and April 2004, we treated 150 patients (111 female, 39 male) with ventral and incisional hernias laparoscopically. Data concerning the age and sex of patients, the location, number, and size of fascial defects, the type of hernias and their contents, the size and type of meshes used in repair, operative time, length of hospital stay, and postoperative complications were collected. RESULTS: Of the 150 patients, 92 had incisional hernias and 58 had umbilical hernias. Polypropylene was used in 85 cases, dual mesh in 40 cases, and composite mesh in 25 cases. The mean age of the patients was 56.0 years (range, 33-81 years). Mean operative time was 63 minutes (range, 30-125 minutes). Mean postoperative hospital stay was 2.5 days (range, 1-15 days). The postoperative complication rate was 8.6% (seroma, paralytic ileus, small bowel injury, and suture-site neuralgia). The mean follow-up period was 32 months (range, 4-60 months). There was a 3% recurrence rate. Three subileus cases were detected during follow-up. CONCLUSION: The laparoscopic approach to ventral and incisional hernias is safe, feasible, and a good alternative to the open approach. Our results are comparable with those of other reports in the literature.

RESUMO

The effects of hyperbaric oxygen (HBO) therapy on oxidant/antioxidant metabolism are controversial and its effects on hepatic regeneration are not known. In this study, we investigated a possible beneficial effect of HBO therapy on oxidant and antioxidants levels during liver regeneration. To conduct this study, seventy percent hepatectomy was performed on forty-eight Spraggue-Dawley rats and the rats were divided into two equal groups: HBO-treated group and untreated group (non-HBO group). We determined the levels of malondialdehyde (MDA), an oxidative stress marker, and the levels of antioxidant enzymes/reagents, including glutathione (GSH), superoxide dismutase (SOD) activity, copper (Cu) and zinc (Zn), in the remnant liver samples. We also measured mitotic index (MI) and proliferating cell nuclear antigen (PCNA) levels to assess the degree of liver regeneration. HBO treatment significantly decreased MDA levels, whereas it increased SOD activity, GSH and Zn levels. In contrast, Cu levels were lower in the HBO-treated livers than the levels in the untreated remnant livers. The effect of HBO treatment may be mediated by the suppression of certain enzymes that are responsible for lipid peroxidation. In addition, HBO treatment may induce the production of antioxidant enzymes/reagents by remnant liver tissues. The HBO-treated rats maintained their body weights but the untreated rats lost body weights. HBO treatment also increased MI and PCNA levels, indicating HBO treatment enhances liver regeneration. These results indicate that HBO treatment has beneficial effects on liver regeneration by decreasing MDA and by increasing antioxidant activities. We therefore suggest that HBO therapy may be useful after liver resection.

RESUMO

BACKGROUND: The aim of the study was to investigate the effects of topical nonsteroidal antiinflammatory drugs (NSAIDs) on mastalgia. STUDY DESIGN: A prospective, randomized, blinded, placebo-controlled study was performed to evaluate the effects of topical NSAIDs on cyclic and noncyclic mastalgia. A total of 108 patients, 60 with cyclic (group I) and 48 with noncyclic (group II) breast pain were enrolled. Patients within each group were randomly assigned to receive either topical NSAIDs or placebo three times daily for at least 6 months. Severity of pain was measured before and after 6 months of treatment. RESULTS: The pain score decreased significantly when the mean initial breast pain score was compared with the sixth-month breast pain score of the treatment or the placebo group of cyclic (p = 0.0001 and p = 0.0001, respectively) or noncyclic mastalgia (p = 0.0001 and p = 0.0001, respectively). Significant differences were found when the mean within-person change in pain values in each treatment group were compared with the change in the respective placebo group for either cyclic or noncyclic mastalgia (p = 0.0001 and p = 0.0001, respectively). Changes in pain within treatment groups or placebo groups for cyclic versus noncyclic mastalgia were not found to be statistically different (p = 0.53 and p = 0.96, respectively). No side effect was seen in any group. CONCLUSIONS: Topical application of NSAIDs was effective in both cyclic and noncyclic mastalgia with minimal side effects.

RESUMO

OBJECTIVE: To compare a systemic transdermal therapeutic system with local application of glyceryl trinitrate ointment in the treatment of anal fissure. DESIGN: Prospective, multicentre, randomised trial. SETTING: Three teaching hospitals, Turkey. SUBJECTS: 89 outpatients with chronic anal fissure were randomly assigned to be treated with either transdermal (n = 52) or 0.2% glyceryl trinitrate ointment (n = 37). INTERVENTIONS: The patients were assessed at the sixth and the twelfth week after initial evaluation by physical examination, anoscopy, and anal manometry. MAIN OUTCOME MEASURES: Changes in the maximal anal resting pressure, healing rate. RESULTS: Anal fissure was completely healed in 38 (73%) and 24 (64%) of the patients after 6 weeks and 48 (81%) and 27 (79%) of the patients in transdermal group and ointment group, respectively. Maximal anal resting pressure was reduced by 24% and 21% in transdermal and ointment groups, respectively. CONCLUSION: Systemic transdermal application of glyceryl trinitrate gave a satisfactory healing rate, which was comparable to that of local application of ointment.

RESUMO

Morgagni-Larrey hernia is a rare type of diaphragmatic hernia, the diagnosis of which is made incidentally by routine chest X-ray film. We describe a technique for the laparoscopic repair of Morgagni-Larrey hernia which was successfully performed in three adult patients; two women and one man. Two of the patients were asymptomatic and had herniation of only omentum into the right hemithorax; however, one was symptomatic and had herniation of the omentum and large bowel. Tension-free closure of the defects was done using Prolene mesh with a hernia stapler, helical fastener, and Endostitch. There were no early complications and the patients were discharged on the fourth postoperative day. The mean follow-up period was 41 months, and there has been no late morbidity or mortality related to this procedure. Using a laparoscopic approach to repair a Morgagni-Larrey hernia provides an excellent view of the surgical field and allows easy manipulation with minimal surgical trauma, followed by rapid recovery of the patient.

RESUMO

PURPOSE: As lateral sphincterotomy and anal dilatation causes complications, a reversible chemical sphincterotomy method has been recently proposed as an alternative treatment in patients with anal fissure. In this study, the effect of botulinum toxin causing temporary paralysis in internal anal sphincter was compared with that of lidocaine in patients with chronic anal fissure. METHOD: A total of 62 outpatients were randomly assigned to receive botulinum toxin or lidocaine pomade. The patients were evaluated before and after two months of treatment with physical examination and anal manometry. Pain and nocturnal pain were scored. RESULTS: In an evaluation period of two months, in 24 of 34 patients of botulinum group (70.58%), and in six of 28 patients of lidocaine group (21.42%) showed complete epithelization (p = 0.006). All patients who had previously reported nocturnal pain became symptom free in botulinum group and in four patients of lidocaine group. Pain following defecation disappeared in 24 patients of botulinum group and in 20 patients of control group (p = 0.959). There was no adverse effect in both groups. While resting anal pressure and maximum voluntary pressure were significantly low in botulinum toxin group, both parameters did not change in lidocaine group. CONCLUSIONS: Botulinum toxin is a reliable and effective method for patients with chronic anal fissure. It can be applied easily without any anesthesia and instrumentation. It is cheaper in comparison with surgical methods and it can be a good alternative treatment in patients with risk of incontinence.
