A review of 43 cases of tetanus neonatorum.

Forty-three patients with neonatal tetanus admitted to the Infectious Diseases Ward of the Istanbul University Faculty of Medicine Children's Hospital at Capa from 1982-1989 are presented. Thirty-two (74.4%) of the subjects were boys. The overall mortality was found to be 60 percent and the mean incubation period 6.1 +/- 20 days. The mean period between onset of symptoms and hospital admission was 1.7 days. Thirty-nine (90.7%) of the 43 patients were unhygienic home deliveries and only two cases were delivered with a midwife in attendance. None of the mothers of the children in our series had been immunized with tetanus toxoid. The incidence of neonatal tetanus in Turkey is on the decline, but a fraction of the population, the so-called urban poor, is still at high risk for preventable diseases. Every contact an unvaccinated person has with a health care professional should be viewed as an opportunity for tetanus immunization.     

The role of surgery in intraabdominal Burkitt's lymphoma in children.

The role of surgery in intraabdominal Burkitt's lymphoma remains controversial and different opinions are present in the literature. In our institution, forty patients (30 boys and 10 girls) with intraabdominal Burkitt's lymphoma with ages ranging from 3 to 12 years have been treated and followed from 1989 through 2000. In ten cases, the patients underwent surgery because of their acute abdominal diseases (intestinal obstruction in 5, intussusception in 3, intestinal perforation in one, and acute appendicitis in one). The remaining thirty patients were referred to our clinic because of their abdominal masses, pain, anorexia and fatigue. Twelve children had localized tumors and total resection could be performed. There was one death in this group due to central nervous system involvement during chemotherapy. In the remaining 28 children, extensive intraabdominal diseases were detected. In four of them, debulking procedures were performed, while in 24 children only biopsies could be made; 8 of them underwent a second-look operation. In the debulking procedures group, two children were lost (50 %) due to tumorlysis and acute renal failure. In the biopsy group, there were six deaths (25 %). All patients received chemotherapy after operative recovery. In conclusion, our results suggest that when the tumor is localized, total resection results in a good outcome. However, in the presence of extensive intraabdominal diseases instead of resection, the operation should be limited to biopsy only.     

Traumatic rupture of hydatid cyst with unusual localization without liver involvement: a case report.

Primary hydatid disease of the intestinal mesentery is rare. We report on a 12-year-old male patient who presented with abdominal pain and urticaria lesions after blunt abdominal trauma. At laparotomy the cyst was found to be ruptured and was totally removed from the surrounding mesenteric tissue.The postoperative course was uneventful. This case is the first child reported with traumatic rupture of a hydatid cyst in a mesenteric location.     

Gait speed is more challenging than cognitive load on the stride-to-stride variability in individuals with anterior cruciate ligament deficiency

Background

Several investigations have studied gait variability of individuals with anterior cruciate ligament (ACL) deficiency; however, the effect of dual-tasking on the gait variability of these individuals remained unclear. The aim of the present study was to determine the effect of gait speed and dual-tasking on knee flexion–extension variability in subjects with and without ACL deficiency.

Sympathetic skin response (SSR) in erythromelalgia

BACKGROUND: Erythromelalgia (EM) is characterized by severe pain associated with local redness and hotness in the extremities. When the extremity is lowered, or heat is applied, the pain is intensified and when coldness is applied, or the extremity is elevated the pain is decreased. OBJECTIVE: To evaluate if there is any sympathetic nervous system involvement in erythromelalgia, sympathetic skin response (SSR) test was done. SETTING: This study was conducted during the years 1998-2000 in the Department of Physical medicine and Rehabilitation, Shiraz University of Medical Sciences. METHODS: SSR study was done on 22 patients with erythromelalgia and 22 normal subjects were matched for age and sex for comparison. RESULTS: There is a significant difference between the patients and controls especially in the lower extremity findings (P = 0.000). More than 72.7% of the patients had abnormal SSR. CONCLUSION: It is concluded that sympathetic peripheral fibers (C fibers) are involved in erythromelalgia and it is probably the pathogenesis of the disease.     

Diabetes education: a chance to improve well-being of Turkish people with type 2 diabetes

To examine the influence of diabetes education on well-being, 255 patients with type 2 diabetes were recruited according to whether they attended a diabetes education program (n=126) or not (n=129). In patients who had participated in the program, the mean anxiety score was significantly lower, whereas positive well-being and general well-being scores were significantly higher than for patients who had not participated. Factors related to lower well-being included: being female, taking insulin, not attending a diabetes education program and having HbA(1c) level greater than 8%. The odds of having better well-being were two-fold higher in patients participating the diabetes education program compared with those who had not. Diabetes education has a crucial role in improving the well-being of patients with type 2 diabetes. All patients with diabetes should be encouraged to attend a diabetes education program.     

Will the new cytogenetics replace the old cytogenetics?

With the advent of array-based comparative genomic hybridization technology, the analog cytogenetic analysis that has been used for the past 100 years could be replaced by the quantitative, microarray-based molecular analysis. Major advantages of the new array-based cytogenetic technologies are the high resolution and the high throughput. This technology is the first to offer an autonomous whole-chromosome analysis in one hybridization reaction for the detection of submicroscopic gains/losses. However, as with any new technology, it needs to be validated with regard to its performance in various applications (e.g. clinical genetic testing and cancer applications), comparative cost, and the data interpretation.     

The effect of polycythemic hyperviscosity on ischemic bowel necrosis

It is known that polycythemia decreases the fluidity of the blood and impairs tissue perfusion due to red-cell sludging in the microcirculation. In this study, the effect of polycythemic hyperviscosity (PH) on bowel necrosis was evaluated in an experimental model of intestinal ischemia. Twenty-eight Wistar albino rats (90–170 g) were divided into two groups: group 1 was transfused to create hyperviscosity and then intestinal ischemia was produced (n = 16); in group 2 ischemia was produced without transfusion (n = 12). Intestinal ischemia was produced by clamping the superior mesenteric artery and the collateral arcades of the right colic artery for 30 min. Gross and histopathologic evaluations were performed by either immediate necropsy or relaparotomy 24 h later. Microscopic findings were graded from 0 to 3 according to the degree of ischemic changes. In group 1, 2 animals (12.5%) died before 24 h postoperatively; coagulation necrosis with grade 2 or 3 ischemic changes was observed in 10 animals (62.5%). In group 2 only a few hypertrophied Peyer's patches and capillary dilation were found, and all histopathologic changes were between grades 0 and 1. The difference between the histopathologic gradings of the two groups was significant (P < 0.001). It appears that in addition to reduced splanchnic blood flow, a secondary effect of PH is needed to induce ischemic coagulation necrosis. PH of the newborn must be considered a risk factor for necrotizing enterocolitis, so-called spontaneous intestinal perforations, and even intestinal atresia.Presented at the 1st European Congress of Pediatric Surgery, Graz/Austria, May 4–6, 1995
