Comparison of preputial sac and urine cultures in healthy children

The aim of the present study was to examine subpreputial bacteriology and to compare it with the urine cultures of healthy male children. Seventy-two male children were divided into two groups as A and B according to age. In both groups preputial sac and urine cultures were taken simultaneously. Gram (+) enteric cocci were the most common isolated pathogens from the preputial sac in group B. Enterobacter, E. coli and staphylococci species were isolated from the urine cultures of three patients in group B. We could not find any difference between the preputial sac swabs of group A and B patients, but the isolation rate of urine cultures of group A patients was significantly higher than group B (p < 0.05). The findings of the present study support a potential role of the prepuce acting as a reservoir of faecal bacteria in the pathogenesis of UTI in male infants, especially in the first year of life. Improved penile hygiene after the first year of life does not alter the subpreputial bacteriology, but significantly decreases the contamination of urine.

Giant angiomyolipoma associated with marked pulmonary lesions suggesting lymphangioleiomyomatosis in a patient with tuberous sclerosis

The association between Tuberous Sclerosis (TS) and Angiomyolipoma (AML) is well known. A patient with TS and giant AML mimicking Renal Cell Carcinoma (RCC), measuring 29 × 18 × 11 cm, weighing 4700 gr is presented. Imaging studies revealed coexistent pulmonary lymphangioleiomyomatosis and concurrent renal and pulmonary involvement is extremely rare in patients in TS. We believe that the growth potential of this hamartomatous lesion may reach to a life threatening size.

Posterior fossa pseudotumour due to viral encephalitis in a child

A 14-year-old boy had a 1-month history of diplopia (due to a VI nerve palsy), motor ataxia and dizziness. Brain MRI showed a 1.5-cm mass posterior to the pons. Histopathological examination of a biopsy specimen showed the lesion to be of viral origin. After 3 months, the ataxia and dizziness had resolved and the MRI findings returned to normal. By 5 months the abducens paralysis had also resolved. Viral encephalitis should be considered in the differential diagnosis of posterior fossa tumours.

Recent experience with Moyamoya disease in Turkey

A series of moyamoya patients is presented. Angiographic findings, outcome of revascularization surgery and a young case with moyamoya disease and hyperphosphatemia are reported. Thirteen patients (6 males and 7 females; age range 2–50 years) were included in the study group. Findings of the patients at presentation were intracranial haemorrhage in two adult cases and sequelae of cerebral ischemia in the rest of the group. One young girl had hyperphosphataemia. Angiography showed distal internal carotid or proximal anterior and middle cerebral artery stenosis, unique collaterals, microaneurysm of the posterior lateral choroidal artery and flow-related changes in the posterior circulation. In 3 patients, encephalo-duro-arterio-synangiosis (EDAS) and burrholes were performed at surgery. Follow-up angiograms of these patients showed revascularization. Moyamoya, a rare but potentially devastating disease, must be addressed as a cause of haemorrhagic and ischaemic cerebral events.

Effect of water extract of Turkish propolis on tuberculosis infection in guinea-pigs.

Mycobacterium tuberculosis (H(37)R(v))-infected guinea-pig model was used to investigate the effect of water extract of propolis (WEP). After subcutaneous inoculation of tubercle bacilli, each animal received oral WEP (n=9), isoniazid (n=5) or saline (n=6) as placebo and were sacrificed 30 days later. Formation of necrosis was less prominent in the group treated with WEP, but was not statistically significant (P>0.05). The granuloma formation in the same group was more prominent than the placebo and isoniazid groups; however, this finding failed to reach statistical significance by the Kruskal-Wallis test (P>0.05). These findings suggest that Turkish WEP may have a limited effect on the development of tuberculosis infection in this guinea-pig model.     

Comparison of randomized preemptive dexketoprofen trometamol or placebo tablets to prevent withdrawal movement caused by rocuronium injection

Rocuronium is a non-depolarizing neuromuscular blocking agent which is associated with injection pain and induces withdrawal movement of the injected hand or arm or generalized movements of the body after intravenous injection. The aim of this randomized study was to compare the efficacy of pretreatment with oral dexketoprofen trometamol (Arvelles^®; Group A) with placebo (Group P) without tourniquet to prevent the withdrawal response caused by rocuronium injection. The study cohort comprised 150 American Society of Anaesthesiologists class I–III patients aged 18–75 years who were scheduled to undergo elective surgery with general anesthesia. The patients response to rocuronium was graded using a 4-point scale [0 = no response; 1 = movement/withdrawal at the wrist only, 2 = movement/withdrawal involving the arm only (elbow/shoulder); 3 = generalized response]. The overall incidence of withdrawal movement after rocuronium injection was significantly lower in Group A (30.1 %) than in Group P (64.6 %) (p < 0.001). The incidence of score 0 withdrawal movements was higher in Group A (69.9 %) than in Group P (35.4 %), that of score 1 withdrawal movements was similar between groups (Group A 21.9 %; Group B 26.1 %) (p = 0.560) and that of score 2 withdrawal movements was lower in Group A (8.2 %) than in Group P (38.5 %) (p < 0.001). There were no score 3 withdrawal movements in either group (p > 0.05). These results demonstrate that the preemptive administration of dexketoprofen trometamol can attenuate the degree of withdrawal movements caused by the pain of the rocuronium injection.
