Intrarenal Surgery vs Percutaneous Nephrolithotomy in the Management of Lower Pole Stones Greater than 2 cm

Purpose

To compare the efficacy of RIRS and PNL in lower pole stones ≥2 cm. Materials and and Methods: A total of 109 patients who underwent PNL or RIRS for solitary lower pole stone between April 2009 and December 2012, were retrospectively analyzed. Lower pole stone was diagnosed with CT scan. Stone size was assessed as the longest axis of the stone. All patients were informed about the advantages, disadvantages and probable complications of both PNL and RIRS before the selection of the procedure. Patients decided the surgery type by themselves without being under any influences and written informed consent was obtained from all patients prior to the surgery. Patients were divided into two groups according to the patients’ preference of surgery type. Group 1 consisted of 77 patients who underwent PNL and Group 2 consisted of 32 patients treated with RIRS. Stone free statuses, postoperative complications, operative time and hospitalization time were compared in both groups.

Results

There was no statistical significance between the two groups in mean age, stone size, stone laterality, mean follow-up periods and mean operative times. In PNL group, stone-free rate was 96.1% at first session and 100% after the additional procedure. In Group 2, stone-free rate was 90.6% at the first procedure and 100% after the additional procedure. The final stone-free rates and operative times were similar in both groups.

Conclusions

RIRS should be an effective treatment alternative to PNL in lower pole stones larger than 2 cm, especially in selected patients.     

Clinical and magnetic resonance imaging findings of the temporomandibular joint and masticatory muscles in patients with rheumatoid arthritis

The aim of this study was to investigate the clinical, radiographic, and magnetic resonance imaging (MRI) findings of temporomandibular joint (TMJ) and masticatory muscles in rheumatoid arthritis (RA) patients. Twenty-eight RA patients and 29 healthy subjects were participated in the study. The patient underwent clinical and laboratory investigation. DAS28 scores were calculated. Lateral panoramic radiography was performed to evaluate condylar erosion and condylar movement. Craniofacial MRI was performed to evaluate TMJ and masseter, medial and lateral pterygoid muscles’ thickness, and cross-sectional area. It was found that the mean maximal interincisal distance, range of lateral, retrusive (P < 0.05) and protrusive motion were all lesser in RA group. Lateral panoramic radiography revealed a distinct erosion in 10.7% (3/28) and restricted condylar movement in 53.6% (15/28) of RA patients. Two RA patients demonstrating marked condylar erosion in lateral panoramic radiographs were RF negative and had DAS28 scores 3.41 and 4.61. MRI findings revealed condylar erosion and effusion in one RA patient and atrophic changes of masticatory muscles in another patient. There was no statistical significance between RA and healthy groups for the thickness and cross-sectional areas of the masticatory muscles. RA group revealed a strong linear relationship for the right and left muscle thickness and cross-sectional areas in regression analysis. TMJ symptoms are frequent findings and thought to be affected from mean disease duration in RA. Laboratory findings should be considered for disease activity–related TMJ involvement. RA patients did not present muscular atrophy or hypertrophy.     

Alexithymia and Emotional Intelligence in Patients with Panic Disorder, Generalized Anxiety Disorder and Major Depressive Disorder

Emotional Intelligence (EI) is a broad personality construct signifying the ability to perceive and to regulate affects within oneself. Alexithymia is another personality construct denoting difficulty in identifying and expressing emotions, with an externally oriented thinking style. Although previously considered to be independent, some studies have shown that these constructs overlap. The aim of this study was to evaluate and compare the levels of EI and alexithymia in patients with panic disorder, major depressive disorder (MDD), and generalized anxiety disorder (GAD). The subjects included 171 psychiatric patients and 56 non-clinical controls. Psychiatric diagnoses were based on DSM-IV criteria. The Emotional Intelligence Scale-34 (EIS-34) and the Toronto Alexithymia Scale (TAS-20) were used to assess EI and alexithymia. All three patient groups scored statistically significantly higher than the non-clinical controls on TAS-20 total score and the TAS-20 subfactors of difficulty identifying feelings and difficulty describing feelings. EIS-34 scores were lower in patient groups than in the non-clinical controls, but only the EIS-34 intrapersonal subscale was significant difference. Total TAS-20 and EIS-34 scores in the patient cohort were inversely and significantly correlated These results reaffirm an overlap between EI and alexithymia with the intrapersonal factor of EI to be more dependent on the difficulty identifying feelings dimension of alexithymia in subjects with MDD and GAD.     

Susac's syndrome: A case of simultaneous development of all three components of the triad

Susac's syndrome is characterized by the clinical triad of encephalopathy, branch retinal artery occlusions and sensorineural hearing loss. We here report a case of 46 year old woman with a sudden diminution in visual acuity at the left eye, headache and decreased hearing at the right ear with mild confusion considered as Susac's syndrome with complete triad. Although it's a relatively rare entity, it should be kept in mind in differential diagnosis of the neurological disorders, especially in women in 20- to 40-year of age presenting with acute hearing loss.
