The concordance of optic nerve sheath diameter measurements with the clinical course in children with traumatic head injury.

BACKGROUND: Intracranial pressure (ICP) monitoring is of profound importance concerning prognosis and treatment among children with traumatic brain injury (TBI). Measurements of the optic nerve sheath diameter (ONSD) are one of the methods recommended for ICP monitoring. In this study, we aimed to evaluate the correlation of ONSD change in brain computed tomography (CT) with pediatric Glasgow Coma Score (pGCS) in the follow-up of pediatric cases with TBI, and also to evaluate the usability of the ONSD, which is the indicator of ICP. METHODS: The data of 921 pediatric patients who were admitted to the emergency department with head injury between January 2016 and January 2018 were retrospectively evaluated in this study. Age, gender, trauma type, brain CT finding, pGCS, type of intracranial hemorrhage (ICH), and isolated skull fracture (ISF) were investigated. The patients were evaluated in three groups based on CT findings: (i) patients with parenchymal brain injury, (ii) patients with ISF, and (iii) patients with normal brain CT results. The measurements of ONSD were performed using CT. Whether the ONSD measurement results of the patients were compatible with the clinical data was investigated. RESULTS: The median age of the patients was 36 months (interquartile range [IQR] = 64) and 64.2% were male. The ONSD values and pGCSs of the patients with parenchymal injury were found to be significantly higher than patients with ISF and normal brain CT findings (p<0.05). The pGCSs showed a significant negative correlation with the first and second measurement results of ONSD (p<0.05). In groups undergoing control brain CT, ONSD levels in the second brain CT were found to be significantly high (p<0.05). CONCLUSION: In the clinical follow-up, ONSD measurements are reliable and significant parameters when evaluated with brain CT findings and pGCSs. We think that repeated ONSD measurements will be useful in determining possible adverse effects of secondary injury, as well as in determining the severity of the trauma during admission.

Perineal rectosigmoidectomy for incarcerated rectal prolapse (Altemeier's procedure).

Perineal procedures have higher recurrence and lower mortality rates than abdominal alternatives for the treatment of rectal prolapse. Presence of incarceration and strangulation also influences treatment choice. Perineal rectosigmoidectomy is one of the treatment options in patients with incarceration and strangulation, with low mortality and acceptable recurrence rates. This operation can be performed especially to avoid general anesthesia in old patients with co-morbidities. We aimed to present perineal rectosigmoidectomy and diverting loop colostomy in a patient with neurological disability due to spinal trauma and incarcerated rectal prolapse.

Study on relationships among deep vein thrombosis, homocysteine & related B group vitamins.

OBJECTIVES: Hyperhomocysteinemia has been considered as a potential risk factor for deep venous thrombosis (DVT) but it is still controversy. We aimed to evaluate the prevalence of hyperhomocysteinemia in patients with DVT. Our second objective was to document the prevalence of folate, Vitamin B6, and Vitamin B12 level in this patient population. METHODS: Sixty patients with DVT aged from 23 to 84 years, were assessed regarding demographic characteristics, serum levels of homocysteine, folate, vitamin B12, and vitamin B6. The diagnosis of DVT was based upon Wells scoring system and serum D-dimer level and confirmed by deep venous Doppler ultrasonography of the lower limbs. RESULTS: Mean serum homocysteine levels were found significantly higher in patients over the age of 40 years (10.81±4.26 µmol/L vs 9.13±3.23 µmol/L). Of all the patients, 9 patients had homocysteine level above the 15µmol/L, 26 had folic acid level below 3 ng/ml, one had vitamin B12 level below 150 pmol/L, and two had vitamin B6 level below 30 nmol/L. In the hyperhomocysteinemic group, five patients had low folic acid level, one had low vitamin B12 level, and two had low vitamin B6 level. CONCLUSIONS: Hyperhomocysteinemia, in women older than 40 years, may be a risk factor for DVT. Folic acid deficiency may also influence serum homocysteine concentrations. Folate therapy may be offered to the patients with DVT. However further studies are required to clarify the underlying molecular mechanisms.

Perforated intestinal leiomyosarcoma as a metastasis of uterine leiomyosarcoma: a case report.

INTRODUCTION: Uterine leiomyosarcomas are relatively uncommon soft tissue neoplasms and rarely metastases to small bowel. In the current case; a patient is suffering from intestinal perforation due to metastatic leiomyosarcoma of the small bowel. CASE PRESENTATION: A 59-year-old woman underwent a modified radical mastectomy for infiltrating ductal cancer of the breast six years ago and a total abdominal hysterectomy for leiomyosarcoma of the uterus two years ago. About 2400 cGy total dose radiotherapy has also been applied after total hysterectomy for bone metastasis of breast cancer. She admitted to our clinic with the complaints of acute abdomen due to perforated small bowel metastasis of leiomyosarcoma during the radiotherapy. Laparotomy was performed and leiomyosarcoma of the ileum was removed totally. Histopathologic examination of the specimen confirmed the presence of the leiomyosarcoma in intestinal tissue samples. CONCLUSION: We aimed to present this unusual case which perforated presentation of the intestinal metastasis of uterine leiomyosarcoma.

Effect of hyperbaric oxygen therapy on healing of diabetic foot ulcers.

Hyperbaric oxygen therapy can be used as an adjunct to standard wound care in the treatment of diabetic patients with foot ulcers. We undertook a prospective, randomized investigation of the use of hyperbaric oxygen therapy versus standard therapy for the treatment of foot ulcers in diabetic patients. A number of demographic variables were analyzed in regard to wound healing. We noted that foot ulcers in patients in the hyperbaric oxygen therapy group were more likely to heal, and were more likely to undergo amputation distal to the metatarsophalangeal joint compared with those patients receiving standard therapy without hyperbaric oxygen. We feel that hyperbaric oxygen therapy should be considered a useful adjunct in the management of foot ulcers in diabetic patients.

Evaluation of P-POSSUM and CR-POSSUM scores in patients with colorectal cancer undergoing resection.

INTRODUCTION: The aim of this study was to evaluate the predictive accuracy of P-POSSUM and CR-POSSUM models on patients undergoing colorectal resection. METHODS: P-POSSUM and CR-POSSUM predictor equations for mortality were applied retrospectively to 321 patients who had undergone colorectal resection for cancer. P-POSSUM and CR-POSSUM scores were validated by assessing their calibration and discrimination. Calibration was assessed using the Hosmer-Lemeshow goodness-of-fit test and the corresponding calibration curves. Evaluation of the discriminative capability of both models was performed using receiver-operating characteristic (ROC) curve analysis. RESULTS: Overall, 22 deaths were observed. CR-POSSUM predicted 25 deaths (chi2 = 12.20, P = 0.13), and P-POSSUM predicted 29 deaths (chi2 =18.85, P = 0.002). ROC curves analysis revealed that CR-POSSUM has reasonable discriminatory power for mortality. CONCLUSIONS: These data suggest that CR-POSSUM may provide a better estimate of the risk of mortality for patients who undergoing colorectal resection.

Outcomes of emergency surgical treatment in malignant bowel obstructions.

BACKGROUND/AIMS: Malignant bowel obstructions are still a challenging problem for surgeons and carry high morbidity and mortality risk. The aim of this study was to review the presentation and outcomes of malignant bowel obstructions and to identify the risk factors related with poor prognosis. METHODOLOGY: One hundred and twenty-five patients underwent emergency surgical treatment for malignant obstructions between January 1997 and January 2002. Data included age, sex, past medical history, presenting symptoms; physical findings on admission, American Society of Anesthesiologists (ASA) class, operative details, postoperative complications, length of hospitalization and hospital mortality were reviewed retrospectively. RESULTS: Seventy-three (58%) of the patients have poor performance status on admission. Potentially curative resection was performed in 74 (60%) patients. Surgical treatment was palliative in 43 (34%) patients. Extended bowel resections were utilized in 20 (16%) patients. Our hospital mortality rate was 21%, and postoperative morbidity rate was 31%. Coexisting cardiopulmonary diseases, presence of generalized perforation, poor general condition and extended bowel resections appeared to be related with unfavorable outcomes. CONCLUSIONS: Emergency surgical treatment for malignant obstruction may be curative in selected patients with good performance status.

Diagnostic value of blood D-dimer level in acute mesenteric ischaemia in the rat: an experimental study.

OBJECTIVE: The high mortality rate of mesenteric ischaemia is mainly due to delay in diagnosis. For this reason, it is of great importance to find a specific and rapidly elevating marker. The present study investigated the diagnostic value of blood D-dimer level as a potential marker for acute mesenteric ischaemia in a rat model. METHODS: Thirty male Wistar albino rats were divided into three groups. Basal D-dimer and L-lactate levels were determined in the non-operative control group (I). In the operated control group (II), the superior mesenteric artery was simply manipulated, while the artery was ligated in Group III. Blood samples were drawn in all groups for D-dimer and L-lactate assays. RESULTS: Both Group II (p=0.016) and Group III (p=0.001) had significantly higher mean D-dimer levels in the first postoperative hour compared with the basal level in Group I. However, there was no difference between the levels in Groups II and III. The mean level in Group II in the sixth hour had dropped to a statistically insignificant level compared with the basal value, while the mean value in Group III kept rising during this period (p=0.001). Nevertheless, there was no significant difference between Groups II and III. On the other hand, the mean L-lactate level in the first postoperative hour in Group III was significantly higher than the basal level in Group I (p=0.003). No significant rises were recorded in Group II in the first and sixth postoperative hours. The difference between Groups II and III in the first hour was significant (p=0.005). Group III also had significantly higher mean serum L-lactate value in the sixth hour compared with both the basal value in Group I (p=0.001) and the sixth-hour value in Group II (p=0.003). CONCLUSION: These results do not adequately support the use of blood D-dimer level as an independent parameter in the diagnosis of mesenteric ischaemia due to arterial thrombosis. However, this parameter can be used together with other tests in eliminating the possibility of a thromboembolic event.

The effects of verapamil vs. allopurinol on intestinal ischemia/reperfusion injury in rats. "An experimental study".

BACKGROUND/AIMS: Although studies have reported that xanthine oxidase inhibitors or calcium channel blockers attenuate the ischemia-reperfusion injury in several organ systems, no comparative study exists on the significance of each of these pathways. To study this, in anesthetized Wistar Albino rats, a surgical model for intestinal ischemia-reperfusion injury was employed. METHODOLOGY: In experimental animals, after laparotomy, the superior mesenteric artery was occluded for 30 min, followed by a 2-h period of reperfusion; control rats underwent only a sham laparotomy procedure. One group of experimental animals was pretreated intraperitoneally with the calcium channel blocker verapamil (0.3 mg/kg), another group with the xanthine oxidase inhibitor allopurinol (100 mg/kg), the third group received no pretreatment. Plasma lactate, malondialdehyde and glutathione levels as well as intestinal tissue malondialdehyde and glutathione levels were measured to assess for possible protective effects. Histologic evaluation of the extent of injury was also performed. RESULTS: Irreversible tissue damage was depicted in the untreated group, and partially in the allopurinol pretreatment group by histologic examination. Ischemia-reperfusion injury was reversible in the verapamil group. The laboratory results also supported these findings. CONCLUSIONS: Protective effects of verapamil on ischemia-reperfusion injury have been found to be significantly (p<0.0001) more effective compared to allopurinol.

Emergency bowel surgery in the elderly.

BACKGROUND/AIMS: Emergency bowel operations are commonly performed in emergency units and carry high morbidity and mortality risk, particularly in elderly patients. The aim of the present study was to review the presentation, management and outcome of bowel emergencies in elderly patients. METHODS: The records of 248 patients (91 females, 157 males) aged over 65 years, undergoing emergency bowel operation during a five-year period, were reviewed. Patient's age, sex, details of presentation, past medial history, presence of coexisting diseases, and type of surgical procedures were noted, and their effects/any unfavorable outcomes were all analyzed. Data were evaluated by using SPSS 9.0 for Windows statistical program. A p value less than 0.05 was accepted as significant. RESULTS: Mean age was 72.5 years. There were 85 (34%) isolated small bowel emergencies (SBE) and 153 (62%) isolated large bowel emergencies (LBE). The most common disease in SBE was mesenteric ischemia in 67 (27%), followed by adhesions, 26 (10%). Malignant bowel disease in 59 (24%) and sigmoid volvulus in 43 (17%) accounted for the majority of LBE. Sixty-five percent (161) of patients presented with obstruction and 46 (19%) patients had bowel perforation. Malignant disease, volvulus and mesenteric ischemia carried high resection rates (82%, 78% and 76%, respectively). Overall morbidity and mortality rates were 42% (105) and 28% (70), respectively. CONCLUSIONS: Emergency bowel operations have poor outcome in the elderly. Nature and extent of disease, presence of coexisting cardiopulmonary disease, late admission and presence of peritonitis significantly affect management and outcome of elderly patients with bowel emergencies.

An unusual presentation of metastatic gastric cancer found during inguinal hernia repair: case report and review of the literature.

Inguinal hernia and intra-abdominal malignancies can coexist, and rarely the hernial sac provides the first evidence of primary or metastatic cancer. Tumors in the hernial sac occur in fewer than 0.5% of all surgically excised sacs. We report a case of metastatic gastric cancer in the inguinal hernial sac confirmed by histopathological examination. Postoperative investigations revealed an adenocarcinoma in gastric corpus. The case is discussed based on the English-language literature.

Primary hydatid cyst of the pancreas related to main pancreatic duct. A case report.

A case of primary hydatid cyst of the pancreas related to the main pancreatic duct is presented. Abdominal ultrasound and computed tomography revealed a cyst at the tail of the pancreas. Endoscopic retrograde cholangiopancreatography showed dilatation of the distal part of the pancreatic duct related to the cystic cavity. While the diagnosis of the pancreatic pseudocyst was established preoperatively, the hydatid cyst was demonstrated at laparotomy and then the final decision of cystogastrostomy was employed. Following the uneventful postoperative period, the patient was discharged on the 8th postoperative day.
