Videothoracoscopy versus intrapleural streptokinase for management of post traumatic retained haemothorax: a retrospective study of 65 cases

BACKGROUND: Post traumatic retained haemothorax (PRH) may cause pulmonary restrictions or septic pleural complications. Currently, minimally invasive procedures such as videothoracoscopy or intrapleural fibrinolysis have replaced open surgery in an effort to avoid these complications. OBJECTIVE: We have reviewed retrospectively our use of videothoracoscopy versus intrapleural streptokinase for the management of PRH over the last 10 years. PATIENTS AND METHOD: There were 56 males and nine females in the study. Thirty-one cases had been managed by intrapleural streptokinase (group I), and videothoracoscopy was performed on 34 cases (group II). Therapeutic results for both groups were determined by chest radiographs. RESULTS: In the population from which we drew our study group, retained haemothoraces occurred in 10.9% of 596 cases with traumatic haemothorax. In group I, 22 patients had radiological improvement; the others underwent thoracotomy. In this group, mean hospitalisation time was 14.5(+/-4.2) days, and three cases were complicated by empyema. In group II, all patients except four had complete radiological improvement; two of them required a decortication. In this group, mean hospital stay was 9.8(+/-3.7) days. There were no deaths in either group. The differences between group I and group II for length of hospital stay and number of thoracotomies was statistically significant. CONCLUSION: Videothoracoscopy is therefore a more effective procedure than intrapleural streptokinase for the management of PRH.     

Assessment of the use of hip ultrasonography by Graf's method between 1 and 6 years of age

Ultrasonographic examinations of both hips of 133 children whose age ranged from 13 to 72 months were performed using the Graf's method. A standard plane which was mandatory prior to the hip typing could be obtained in 93, 91, 84, 79 and 66% of the sonograms for 13-24, 25-36, 37-48, 49-60 and 61-72 months age groups, respectively. The 61-72 months age group had the lowest percentage of valid sonograms and this difference was considered significant (P=0.001). It was concluded that plain radiography was still the gold standard imaging technique in developmental dysplasia of the hip, but hip ultrasonography by the Graf's method might be an alternative imaging technique in experienced hands for the evaluation of developmental dysplasia of the hip in children between 1 and 5 years of age.     

Novel approach to aortic cannulation suturing: tangential suture technique

BACKGROUND: Pursestring suture for ascending aortic cannulation in open heart surgery that requires cardiopulmonary bypass may cause serious events, especially in patients who have a thin or calcific aorta. We introduce a novel suturing method, called the 'tangential suture technique', and submit our clinical experience. METHODS: Adult patients undergoing cardiopulmonary bypass were included in this study. Patients in whom the tangential suture technique was applied (Group A; n = 146) were compared with patients in whom the classic pursestring technique was applied (Group B; n = 152). RESULTS: The age (38 +/- 11 years vs 36 +/- 10 years), sex (males 65.1% vs 62.5%) and operation types were similar in both groups. Although the difference was not significant (P > 0.05), subadventitial haematoma occurred more frequently in Group B (13 patients; 8.6%) than in Group A (3 patients; 2.1%). However, none in Group A required opening the adventitia. No aortic dissection was observed in peri- or postoperative periods in either group. In Group B, seven (4.6%) patients required repair by suture after tying of pursestring sutures following decannulation because of bleeding, while none was required in Group A (P = 0.0156). CONCLUSIONS: Tangential suture technique allows the needle to take a longer segment from the media layer while decreasing the likelihood of entering the lumen. Because the tract of the suture almost perfectly fits to the needle curve, tissue injury is less, even on fragile aortas, and this ensures more stable closure of the hole when the suture is tied following decannulation. By considering both its theoretical advantages and our clinical experience, we believe tangential suture technique should be preferred to the classic method.

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.     

Use of fascia component of the anterolateral thigh flap for different reconstructive purposes

The anterolateral thigh flap is commonly used for reconstruction of soft-tissue defects located at various sites of the body. This versatile flap offers many advantages to the reconstructive microsurgeons for the treatment of difficult defects. From 2000 to 2005, 70 anterolateral thigh flaps were transferred to reconstruct soft-tissue defects. We retrospectively reviewed these patients and found that the fascia lata component of the flap was used for different purposes in 19 patients. The fascia lata component of the flap was used for suspension of the flap in lip reconstruction in 12 patients, for reconstruction of dural defect in the scalp in 2 patients, for reconstruction of tendon defects in the forearm in 3 patients, and for reconstruction of fascia defect in the abdominal wall in the remaining 2. Complete loss of the flap was seen in an anterolateral thigh flap (5.2%) that was used for lower lip reconstruction. One flap necrosed partially (5.2%), and it was treated with surgical debridement and transposition of latissimus dorsi musculocutaneous flap. The objective of this study is to focus on the reliability of the fascial component of the anterolateral thigh flap. Although many authors have described other advantages of the anterolateral thigh flap extensively, this peculiarity has not been stressed adequately. Anterolateral thigh flap offers a thick and vascular fascial component with large amounts that can be used for different reconstructive purposes, and it should be taken into consideration as an important advantage of the flap, together with other well-known advantages.     

TLR-2 gene Arg753Gln polymorphism is strongly associated with acute rheumatic fever in children

The recently described family of toll-like receptors (TLRs) is a key player in host immunity by mediating inflammatory reactions against a wide range of pathogens. Mutations and polymorphisms in TLRs have revealed the importance of TLRs in human defence against diseases. TLR-2 is reported to interact with different bacterial structures, including lipoproteins, peptidoglycan and lipoteichoic acid. To assess the role of TLR-2 gene polymorphism in acute rheumatic fever (ARF) etiopathology, 61 independent Caucasian Turkish patients and 91 child and 116 adult controls were studied. Antistreptolycin O, C-reactive protein, sedimentation and white blood cell counts were studied to evaluate the clinical characteristics of the patients. Genomic DNA was extracted from peripheral blood using a standard column extraction technique. The Arg753Gln and Arg677Trp polymorphisms were genotyped by polymerase chain reaction (PCR) restriction fragment length polymorphism. The PCR products for the TLR-2 gene were analysed on 1.5% agarose gel pre-stained with ethidium bromide. Compared with healthy adult controls, the Arg753Arg genotype was significantly decreased in the entire group of ARF cases [odds ratio (OR) 0.01, 95% confidence interval (95% CI) 0.0034–0.031, p<0.0001]. Significantly, ARF patients were just 16 times more frequent with Gln allele (OR 15.6, 95% CI 7.87–30.8, p<0.0001). Moreover, evidence for an intensifying effect of the Gln allele was noteworthy when patients with Arg753Gln genotype were compared with healthy controls (OR 97.1, 95% CI 32.5–290, p<0.0001). However, no Arg677Trp polymorphism was detected in either patients or controls. Our data suggest that there is strong evidence for the biological role of TLR-2 in ARF. The common TLR-2 Arg to Gln polymorphism at position 753 significantly contributes to the pathogenesis of ARF. These results will allow the construction of a profile of individuals prone to ARF and may assist in developing new therapies.     

Delayed gastric emptying in gastroesophageal reflux disease: the role of malrotation

The association between gastroesophageal reflux (GER) and intestinal malrotation (IM) has been well described. Delayed or impaired gastric emptying in IM is thought to be a contributing factor in the development of gastroesophageal reflux disease (GERD). The current study assessed the role of malrotation in delayed gastric emptying in children with GERD. We also evaluated the interactions between GERD, malrotation, gastric pH abnormalities, and gastric dysmotility. Sixty-seven patients between 1 and 5 years of age (mean 3.08±1.2) and with symptoms of GER, such as emesis, reactive or recurrent lung disease, and/or growth retardation, were studied in 2001–2005. Upper and lower gastrointestinal contrast studies were performed for the diagnosis of malrotation. Gastric motility was evaluated with a liquid gastric emptying protocol. GER was documented by upper gastrointestinal studies, scintigraphy, and/or 24-h pH monitoring. In our series of 44 children with GERD, there was an unexpectedly high incidence of IM: 54.5% (24/44). IM has previously been known to occur in 25% of patients with GERD. GERD was found in 24 (82.7%) of 29 patients with IM. Mean nuclear gastric emptying (MNGE) was 51.6±8.04 min in patients with isolated GERD and 96.6±20.5 min in children with IM and GERD. There was a statistically significant difference in MNGE time (p<0.05) between children with primary GERD and in those with GERD and IM. Esophageal pH monitoring showed that mean fraction time below pH 4 was 7.06±1.1% in patients with isolated GERD and 14.7±4.1% in patients with IM and GERD. GERD is common in children between 1 and 5 years old. Using gastric emptying studies and esophageal pH monitoring, we have shown that gastric dysmotility and esophageal pH abnormalities are highly prevalent, especially in children with malrotation compared with children with isolated GERD. These findings suggest that malrotation is an important factor responsible for delayed gastric emptying in GERD. Hence, we recommend that all infants and children with GERD and delayed gastric emptying undergo careful evaluation for malrotation.     

Answer to hypotonia: a simple hemogram

A 1-year-old boy with weight loss, decreased activity, and psychomotor regression is presented. He was subjected to an extremely detailed evaluation, including electroencephalography (EEG) and magnetic resonance imaging (MRI), until a simple hemogram in our center revealed that he had macrocytic anemia with megaloblastic changes in the bone marrow. His history revealed that he had been exclusively breast-fed by his vegetarian mother. Further investigations showed low serum vitamin B12 concentration, methylmalonic aciduria, and homocysteinemia, indicating that the macrocytic anemia was due to vitamin B12 deficiency. This boy represents a case of macrocytic anemia and hypotonia owing to vitamin B12 deficiency that developed because of exclusive breast-feeding by a vegetarian mother.
