Blood pressure, heart rate and temperature variability during periodontal surgery

The aim of the present study is to investigate changes in blood pressure, pulse rate and temperature before and after periodontal surgery. The study included 127 normal healthy patients (43 males, 84 females) with age range 9 to 65 years (mean age: 26 +/- 12 years) who underwent periodontal surgery. After administration of a local anaesthetic agent (Ultracain DS) containing 0.06 mg adrenaline, the blood pressure, pulse rate, and temperature were measured. Based on the type of operation, the patients were divided into four groups. Statistically significant changes (as decreasing) in all parameters were observed (blood pressure: systolic 111.3 +/- 20.1, diastolic 67.7 +/- 13.1, pulse rate: 87.8 +/- 14.9, temperature: 36.3 +/- 0.3 ) but these changes were significantly decreased after operations (blood pressure: systolic 105.9 +/- 19. 7, diastolic 62.6 +/- 11.3, pulse rate: 84.01 +/- 13.1, temperature: 36.2 +/- 0.3). And without age group differentiation in all parameters, statistically significant decreases were found among females (p < or = 0. 05).

Early malignant change in a solitary neurofibroma not associated with neurofibromatosis: a case report

A 31-year old woman presented with a mass on the posterolateral aspect of the lower third of the right leg. The mass had undergone fine needle aspiration biopsy previously at another center and was diagnosed as neurofibroma. The patient was evaluated to determine the existence of neurofibromatosis but no positive findings were obtained, thus the mass appeared to be a solitary, local neurofibroma. The mass was totally excised with the involved nerve fascicles. The histopathological evaluation showed foci of malignant transformation of the solitary neurofibroma. The patient was reoperated on, and the surrounding tissues were widely excised together with the tibial nerve; the defect was grafted with the sural nerve. Clear margins were achieved. No complications ocurred and the patient was satisfied. She survived and had neither recurrence nor metastasis during 2 years follow-up. This patient is presented as a case report of a malignant peripheral nerve sheath tumor, specifically the focal malignant degeneration of a solitary neurofibroma.     

The use of a combined technique in reduction mammaplasty (inferior pyramidal and superior glandular techniques)

The management of mammary hypertrophy is a developing process. The common surgical options for reduction mammaplasty include amputation with free nipple graft as well as the bipedicled, inferior pedicle and vertical pedicle techniques. All techniques are used widely. Disadvantages of these procedures include nipple areola necrosis, insensitivity, hypopigmentation, and poor breast projection. Even with the standard modifications of the original techniques, the resultant breast and nipple may be wide and flat. The purpose of this study was to assess whether combined inferior pyramidal pedicle and superior glandular pedicle reduction mammaplasty can optimize nipple and breast projection. Attention will focus on the viability and sensation of the nipple areola complex. Nine patients with mammary hypertrophy were studied. The change in nipple position ranged from 7 to 13 cm. The amount of tissue removed from each breast ranged from 500 to 1150 g. Nipple/areola sensation was retained in all cases with the exception of one breast. Nipple/areola necrosis or hypopigmentation were not observed. Optimal central breast projection was maintained in all patients, and postoperative evaluation was carried out at 12 and 22 months. The patient satisfaction was very high.     

Mitral annular calcification and brown tumor of the rib in a child with chronic renal failure

Mitral annular calcification and liquefaction necrosis of this lesion mimicking intracardiac tumor because of secondary hyperparathyriodism have been described in adult patients with chronic renal failure, but have not been reported in children. Chronic renal failure is one of the predisposing factors of this condition. We report the case of a 13-year-old patient with continuous ambulatory peritoneal dialysis with severe hyperparathyroidism who was found to have intracardiac and rib lesions considered to be brown tumors.     

Postnatal management of infants with antenatally detected hydronephrosis

With the increasing use of antenatal sonography, fetal hydronephrosis has been reported more frequently. Because of the lack of consensus regarding treatment of these infants, the postnatal approach toward fetal renal pelvis enlargement remains controversial. The aim of this prospective study is to demonstrate the postnatal investigation, treatment, and outcome of infants with prenatally diagnosed hydronephrosis. Infants whose antenatal ultrasound scan showed a fetal renal pelvis of 5 mm or greater were investigated postnatally using ultrasound (US) and voiding cystourethrography. When indicated, isotope studies and intravenous urograms were also performed. We followed prospectively neonates with antenatally diagnosed hydronephrosis and recommended management guidelines on the basis of our findings. In 156 neonates (193 kidney units) that were found to have hydronephrosis, the average gestational age at which the diagnosis was made was 32.94±5.10 weeks. The mean duration of postnatal follow-up was 26.3±13.56 months (range 3–60 months). The mean APPD of the fetal renal pelvis was 10.35±3.24 mm (5–9 mm in 84 kidneys, 10–14 mm in 96 kidneys and 15 mm in 13 kidneys). Of the 193 kidney units, 145 units were found to be pathological. The most common detected underlying abnormalities were ureteropelvic junction obstruction (in 91 kidneys; 62.7%) and vesicoureteral reflux (in 24 kidneys; 16.6%). Postnatally, 23 (45%) of 51 patients whose first US was normal were diagnosed postnatally as having urinary tract abnormality. There was a negative correlation between APPD and the rate of spontaneous resolution and positive correlation between APPD and the rate of surgery (P<0.01). In conclusion, because it is not possible to determine an upper limit of normal for the antenatal renal pelvis, any baby with AH should not be considered clinically insignificant. Infants with antenatal renal pelvis measurements 5 mm should be investigated postnatally. A normal postnatal ultrasound scan does not preclude the presence of urinary tract abnormality.     

Effects of Gender on the Severity of Sepsis

Purpose To investigate the differences between male and female rats and the effects of sex hormones on tissue changes in the lung and liver in a sepsis model.Methods Sixty Sprague-Dawley rats were divided into six groups of ten. Groups 1 and 2 were the control male and female groups, respectively, subjected only to sepsis; groups 3 and 4 were the male and female groups, respectively, subjected to sepsis, then given 0.04mg/kg estrogen + progesterone (E-P) intramuscularly (i.m.); and groups 5 and 6 were the male and female groups, respectively, subjected to sepsis, then given 0.5mg/kg testosterone (T) i.m. The rats were killed and the histopathological changes in the lung and liver were examined, and plasma endotoxin levels were measured.Results Histopathological examination revealed less congestion, portal inflammation, and focal necrosis of the liver, and less congestion, edema, and emphysematous and inflammatory changes in the lung in the E-P groups than in the other groups. Moreover, signs of systemic endotoxemia in plasma were proportionally less in the female rats and in the E-P groups than in the male rats and the T groups.Conclusion Female rats subjected to sepsis showed less liver and lung tissue damage and less systemic endotoxemia than male rats, because of the effects of female sex hormones.     

Inflammatory Myofibroblastic Tumor of the Ileocecal Mesentery Mimicking Abdominal Lymphoma in Childhood: Report of Two Cases

An inflammatory myofibroblastic tumor is an uncommon benign tumor located in various organs that can be misdiagnosed as a malignant neoplasm. We herein present two patients with ileocecal inflammatory myofibroblastic tumors. An abdominal mass was detected in a 13-year-old girl and a 15-year-old boy who presented with paleness, fatigue, intermittent fever, and night sweating. The radiological findings confirmed a mass originating from the ileocecal region. The presumptive diagnosis was Burkitt’s lymphoma. The histopathological diagnosis was inflammatory myofibroblastic tumor. After a surgical resection, all systemic symptoms rapidly resolved. Inflammatory myofibroblastic tumor is a rare pseudosarcomatous clinical and pathological entity. Although this tumor is more commonly reported in the lung, it can be detected in extrapulmonary sites, including the mesentery. Because the choice of treatment for this tumor is conservative surgery, an accurate preoperative analysis is important to avoid any unnecessary aggressive surgical intervention or other therapeutic approaches.     

Sexual function in women with urinary incontinence

To date limited data exists that addresses the impact of urinary incontinence on sexual function. In the present study, we assessed sexual functions in patients with urinary incontinence and compared with healthy continent subjects by means of Female Sexual Function Index (FSFI) questionnaire. A total of 21 premenopausal incontinent women (three stress incontinence, nine overactive bladder and nine mixed incontinence) were enrolled in the study, and 18 healthy continent subjects served as controls. All subjects were asked to complete FSFI questionnaire and each FSFI domain scores including desire, arousal, lubrication, orgasm, satisfaction and pain were calculated. The mean scores in each domain were compared between the groups. Mean age of subjects with urinary incontinence and controls were 39.5+/-6.6 and 32.6+/-9.1 y, respectively. All domain scores were significantly lower in incontinent women except for pain. Among the incontinence types, no significant difference was determined in all domains of FSFI. Urinary incontinence significantly reduces sexual functions in premenopausal sexually active women.
