From cyanosis to diagnosis: A case report on right atrial fibroma in a pediatric patient

A 3-year-old female patient presented with symptoms of cyanosis and intermittent eyelid edema, leading to the discovery of a lobulated mass in the right atrium, obstructing the superior vena cava. Despite the inability to entirely remove the mass due to its origins in the right atrium myocardium and its extension towards the sinoatrial node, successful surgical intervention and subsequent histopathological evaluation identified the mass as a fibroma, and postoperative symptoms were significantly alleviated.     

Horseshoe kidney for transplant: report of 3 cases

Owing to the limited donor pool at transplant centers, grafts may be taken from marginal donors with congenital abnormalities, one of the most common of which is a fusion abnormality. Horseshoe kidneys may be transplanted to a single recipient en bloc or to 2 recipients after division. In our clinic, 3 grafts (1 obtained from a living donor and 2 from a deceased donor) were successfully transplanted to 3 patients. In select patients, horseshoe kidneys may be used for transplant.     

The vascular anatomy of the lumbrical muscles in the hand.

The lumbrical muscles are located in the midpalm, dorsal to the palmar aponeurosis. The main function of these muscles is an indirect contribution to interphalangeal joint extension by decreasing the flexor effect of the flexor digitorum profundus muscle. Due to their minor biomechanical functions and suitable constructions, these muscles have been preferred in reconstructive surgery as local transposition flaps or pedicled flaps. Despite the surgical and clinical importance, vascular anatomical studies of these muscles are not well represented in the current literature. This study was performed in the Department of Anatomy of the Faculty of Medicine of the Ege University. Thirty-four cadaver hands, injected with red-coloured latex were used, and we aimed to describe the morphometry and vascular anatomy of the lumbrical muscles. We measured the length and width of the muscles, after removing their epimisium, and the diameter and length of the arteries to the muscles. The outcomes of our study determined that the length and width of the lumbrical muscles were reduced significantly from radial towards ulnar sides. The lumbrical muscles were supplied from both their palmar and dorsal surfaces by both superficial and deep palmar arches and/or their branches. We also described the level of entry of the dominant arteries for each lumbrical muscle and measured the size of the vessels and muscles to guide some surgical approaches. This anatomical study could guide for some surgical approaches and reduce the deficiency about the vascular anatomical patterns of the lumbrical muscles in the literature.     

Patient-controlled epidural analgesia after major urologic surgeries. A comparison of tramadol with or without bupivacaine

The efficiency and safety of patient-controlled epidural analgesia by using tramadol alone and combined with bupivacaine were investigated for postoperative pain treatment after major urological surgeries. For PCEA: in group I (n = 17) a loading dose of 20 mg tramadol with a continuous infusion of 1 mg/ml tramadol at a rate of 8 ml/h was given. In group II (n = 17), patients received an initial loading dose of 20 ml bupivacaine 0.125% and a supplemental continuous infusion of 8 ml/h. In group III (n = 17), a loading dose of 20 mg tramadol with 20 ml bupivacaine 0.125% were given and a supplemental infusion of 1 mg/ml tramadol in 20 ml bupivacaine 0.125% combination was begun with a rate of 8 ml/h. A demand epidural bolus dose of 5 ml with a lockout time of 30 min was also used in all patients. VAS for pain intensity, vital signs, sedation scale and side effects was monitored at 0, 15, 30 min and 1, 2, 3, 4, 8, 12, and 24 h of the postoperative period. Statistical significance was determined using Kruskal-Wallis, Fisher's exact, analysis of variance for repeated measurements and Tukey tests. The hemodynamic values and sedation scales were insignificantly different (p > 0.05). The adequate analgesia was provided in all patients. However VAS values were significantly lower in group III than in groups I and II at every measurement (p < 0.05). The incidence of side effects in all three groups was low (p > 0.05). In conclusion, we suggested that a combination of tramadol with bupivacaine can provide the most effective and safe postoperative analgesia with minimal risk for side effects.     

Correlation Between the Renal Resistive Index (RI) and Nonenhanced Computed Tomography in Acute Renal Colic

OBJECTIVE: The purpose of this study was to determine the sensitivity of renal color Doppler sonography in differentiating obstructive and nonobstructive urinary calculi in patients with acute renal colic and to compare findings with nonenhanced helical computed tomography (CT). METHODS: Sixty-five patients referred to the emergency department with acute renal colic underwent nonenhanced CT and renal resistive index (RI) measurement with color pulsed Doppler sonography within 8 to 10 hours of the onset of the symptoms. Computed tomographic evaluation was based on the detection of urolithiasis and classification according to location and the presence of obstruction. The mean RI of each kidney and the difference between the mean RI (DeltaRI) of both kidneys were calculated and compared with CT findings. RESULTS: A total of 164 stones were identified. Computed tomography revealed obstruction in 33 patients. Mean RI values for the obstructive and nonobstructive groups were 0.64 and 0.63, respectively. Mean DeltaRI values were 0.01312 and 0.01000 in the obstructive and nonobstructive groups. The differences in the mean RI and DeltaRI for the patients with and without obstruction were statistically insignificant (P = .73). No significant relationship was found between the RI values, calculus location, and degree of obstruction. CONCLUSIONS: The RI is insensitive for detection of obstruction in patients with acute renal colic, and its value in routine practice seems quite controversial.     

Sex work, drug use, HIV infection, and spread of sexually transmitted infections in Moscow, Russian Federation

Rates of HIV-1 infection are growing rapidly, and the epidemic of sexually transmitted infections is continuing at an alarming rate, in the Russian Federation. We did a cross-sectional study of sexually transmitted infections, HIV infection, and drug use in street youth at a juvenile detention facility, adults at homeless detention centres, and women and men at a remand centre in Moscow. 160 (79%) women at the remand centre were sex workers. 91 (51%) homeless women had syphilis. At least one bacterial sexually transmitted infection was present in 97 (58%) female juvenile detainees, 120 (64%) women at the remand centre, and 133 (75%) homeless women. HIV seroprevalence was high in women at the remand centre (n=7 [4%]), adolescent male detainees (5 [3%]), and homeless women (4 [2%]). In view of the interaction between sexually transmitted infections and HIV infection, these findings of high prevalence of sexually transmitted infections show that these disenfranchised populations have the potential to make a disproportionately high contribution to the explosive growth of the HIV epidemic unless interventions targeting these groups are implemented in the Russian Federation.
