Angiomyolipoma of the uterus associated with tuberous sclerosis: case report and review of the literature

BACKGROUND: Angiomyolipoma (AML) is a rare benign tumor that occurs most commonly in the kidney. Only a few cases have been described in the uterus. CASE: We describe a 32-year-old woman with tuberous sclerosis who presented with irregular bleeding. Preoperatively, the lesions were confused with leiomyoma on ultrasound. At laparotomy, multiple circumscribed subserosal and intramural purplish lesions on the corpus uteri were noted leading to a diagnosis of uterine angiomyolipoma with the histological and immunohistochemical findings. CONCLUSION: In contrast to other reported uterine angiomyolipoma cases, HMB-45 melanoma-specific antibody immunoreactivity is demonstrated in the present case. The histopathologic diagnosis as well as immunohistochemical analysis is discussed here with a review of the literature.     

Does patient education increase antimuscarinic treatment persistence in overactive bladder syndrome?

Overactive bladder syndrome (OAB) is a chronic condition that requires long‐term management. Patient education may have role in decreasing the unfavourable effects of long‐term treatment of OAB. The aim of the study was to evaluate the effect of detailed patient education on the patients' persistence with antimuscarinic treatment for OAB. A total of 140 patients with the diagnosis of OAB were included in this study. Patients were randomly divided into two groups. Patients in Group 1 were given information by the same urology doctor about the disease and treatment. Patients in Group 2 were given information by a urology nurse. Patients were recalled in the first, third and sixth months of treatment. The treatment persistency was evaluated in the whole study population and between the groups. The persistency rates of the whole group were 88·6% in the first month, 65·7% in the third month and 45·7% in the sixth month. At the end of the sixth month, 42·8% of males and 47·1% of females were taking antimuscarinics (p = 0·580). The persistence rate of Groups 1 and 2 were 82·8 and 94·3% at the first month. (p = 0·034). It decreased to 31·4% in the first and 60% in the second group at the sixth month (p = 0·001). The persistence rate of antimuscarinic treatment is low. Patient education is simple and effective way of increasing persistence. Clinicians must pay attention to inform their patients about the disease and possible side effects of treatment. An educated health provider may be very helpful in educating patients for OAB.     

Sulcus vocalis in monozygotic twins

Sulcus vocalis is the presence of a groove extending along the vibratory surface of a vocal fold and may result in dysphonia. Depending on the level of severity, this condition may require treatment involving complicated surgical techniques. Cases of sulcus vocalis are classified as physiological, vergeture, or pouch type. A clear explanation of the etiology has not been established, and the currently proposed congenital origin, as described in the literature, remains controversial. This paper presents findings from monozygotic twin sisters with bilateral sulcus vocalis; these patients had similar morphologies, vibratory characteristics, and vocal quality measurements, which support the theory of a congenital etiology.     

Cirsoid aneurysms of the scalp

This study reviewed the surgical management of cirsoid aneurysms of the scalp, which are rarely encountered in the neurosurgical practice, and compares the results with embolization. 21 patients with cirsoid aneurysm underwent surgery. There were 1 female and 20 male patients. Trauma was present in four patients. Selective internal and external carotid artery angiograms and cranial magnetic resonance imaging studies were performed on all patients. All angiograms were staged according to published procedures. There were 15 (71.4%) Stage 1a, 4 (19.1%) Stage 1b, and 2 (9.5%) Stage 3 patients.Total excision of the lesion was achieved in 19 patients (90.5%). We operated on only one patient for a second time, because of a residual lesion, and we resected the lesion totally. Only two patients developed necrosis of the scalp (button hole). Both scalp necroses were on the frontal area. Other patients all had good cosmetic results. Surgical resection of cirsoid aneurysms seems to be the most effective treatment with good results. There may be a tendency for the occurrence of necrosis on the frontal area. Staging of the scalp aneurysms has no effect on surgical outcome.     

An in Vitro Experimental Study on the Antimicrobial Activity of Silicone Oil against Anaerobic Bacteria

Purpose: To investigate the in vitro antimicrobial activity of silicone oil against anaerobic agents, specifically Propionibacterium acnes, Peptostreptococcus spp., Peptostreptococcus anaerobius, Bacteroides fragilis, Fuobacterium spp., and Clostridium tertium.

Method: A 0.5 McFarland turbidity of Propionibacterium acnes, Peptostreptococcus spp., Peptostreptococcus anaerobius, Bacteroides fragilis, Fuobacterium spp., and Clostridium tertium was prepared, and 0.1?mL was inoculated into 0.9?mL of silicone oil. Control inoculations were performed in anaerobic blood agar and fluid thioglycollate medium without silicone oil.

Results: Propionibacterium acnes retained their viability on the 3rd day in the presence of silicone oil. In total, 9.7?×?10⁶ colonies were enumerated from 1?mL of silicone oil. After a prolonged incubation of 7 days, the number of colonies observed was 9.2?×?10⁶. The other bacteria disappeared after the 3rd day of incubation in silicone oil.

Conclusions: Propionibacterium acnes, which is the most common chronic postoperative endophthalmitis agent, is thought to be resistant to silicone oil.     

Comparing the cochlear spiral modiolar artery in type-1 and type-2 diabetes mellitus:a human temporal bone study

This study examined whether pathological findings were present in cochlear vessels for patients with diabetes mellitus. Twenty-six temporal bones from 13 patients with type 1 diabetes mellitus and 40 temporal bones from 20 patients with type 2 diabetes mellitus were examined. Type 2 diabetic temporal bones were divided into 2 groups according to diabetic management (22 temporal bones with insulin therapy, and 18 with oral hypoglycemic drugs). Age-matched normal control temporal bones were also selected. The vessel wall thickness in the cochlear spiral modiolar artery was measured under a light microscope, and the vessel wall ratio (vessel wall thickness/outer diameter of the vessel x 100) was calculated. The vessel wall thickness and vessel wall ratio in type 1 diabetes mellitus were significantly greater than in normal controls. Type 2 diabetic patients with insulin therapy showed significantly greater vessel wall thickness and vessel wall ratios than controls. In type 2 diabetes mellitus, the vessel wall thickness and vessel wall ratio were greater in patients treated with insulin therapy than in those treated with oral hypoglycemic agents. Type 2 diabetic patients with insulin therapy showed an increased vessel wall thickness and vessel wall ratio compared to patients with type 1 diabetes mellitus. In conclusion, the cochlea in patients with diabetes mellitus shows circulatory disturbance compared to age-matched normal controls.     

Congenital os vomer agenesis: case report and literature review

Defects of the nasal septum occur as a result of a variety of causes, including tuberculosis, irritation, neoplasia, trauma, infection, and chronic inflammatory diseases. Congenital os vomer agenesis as a cause is very rare. We report the case of a 28-year-old man with a defect in the posteroinferior part of the nasal septum that was discovered incidentally during a routine endoscopic examination. The patient was diagnosed with congenital os vomer agenesis, and the diagnosis was confirmed by computed tomography. We discuss the features of this case and review the literature on this rare anomaly.     

Bilateral symptomatic petrous apex effusion

Petrous apex effusions can present with aural fullness, hearing loss and dizziness. Although they can be followed-up when asymptomatic, clinical management of symptomatic patients is controversial. In this study, we present clinical and radiological findings of a 24-year-old patient with bilateral petrous apex effusion. She had been complaining of bilateral aural fullness and dizziness for 2 years. Radiological examinations revealed bilateral petrous apex effusion. After medical treatment, her symptoms gradually disappeared. In all previous published studies, unilateral petrous apex effusions were reported. To our best knowledge, this is the first patient with trapped fluid in bilateral petrous apex.
