In 2009, a 52-year-old man presented with a two year history of intermittent right-sided pulse-synchronous tinnitus. He noted that the tinnitus worsened when his blood pressure was elevated. Otologic exam was unremarkable, with no obvious middle ear fluid or mass. There was no neck bruit, and the tinnitus diminished on manual compression of the ipsilateral internal  jugular vein. In keeping with the recommendations for clinical imaging at that time, a non-contrast CT of the temporal bone was performed. This was to evaluate for conditions such as : a middle ear glomus, an aberrant internal carotid artery, a jugular bulb variant (e.g. a high-riding jugular bulb), otosclerosis, superior semicircular canal dehiscence syndrome, a persistent stapedial artery, or a hemangioma of the temporal bone.1 No evidence of these conditions was found. An MRI of the brain, with MR angiography and venography of the intracranial vasculature also performed to evaluate for conditions such as:  idiopathic intracranial hypertension, a dural arteriovenous fistula, an arteriovenous malformation, vascular loop syndrome, and dural sinus stenosis or thrombosis.2 All of these conditions were excluded. As no definite pathology was identified, no firm treatment reommendations were initiallly made.

In 2011, Eisenman reported on a series of 13 patients with pulsatile tinnitus due to a sigmoid sinus diverticulum and/or dehiscence who were successfully treated surgically via an extraluminal transmastoid approach.3 This was the first relatively large series published in the otologic literature. This publication likewise reported on the subtle radiologic signs that signify the presence of a sigmoid sinus diverticulum and/or dehiscence, such as an irregularity of the normal semicircular contour of the bony sinus wall, focal thinning of the calvarial cortex overlying the adjacent sinus wall, absence of the normal thin layer of cortical bone overlying the sinus, and the "air-on-sinus" sign, where mastoid air cells directly contact the sinus wall, without overlying bone.3

In light of this new information, the patient's imaging studies were re-evaluated, and evidence of a right-sided sigmoid sinus diverticulum and/or dehiscence was identified. The images below show the findings on an axial slice of the patient's temporal bone CT study.

 

How significant is this condition ? Sigmoid sinus diverticulum and/or dehiscence is being increasingly recognized as a common cause of pulsatile tinnitus. In fact, a recent study by Schoeff et al. found its prevalence to be 23% in patients with pulsatile tinnitus.4 As such, the identification of this condition is highly relevant, particularly because effective surgical management is available for its alleviation.

OBJECTIVETo study the influence of male age on the outcome of conventional IVF-ET.

METHODSBased on male age, 170 couples undergoing conventional IVF-ET were divided into three groups: <35 yr (n = 60), 35 -39 yr (n = 77) and > or = 40 yr (n = 33). We observed the rates of fertilization, cleavage, good quality embryo, implantation, clinical pregnancy and abortion in different groups.

RESULTSThere were no significant differences among the three groups in semen volume ([3.10 +/- 1.22] ml vs [2.84 +/- 1.05] ml vs [2.80 +/- 0.79] ml), sperm concentration ([54.23 +/- 26.07] x 10(6)/ml vs [60.27 +/- 24.80] x 10(6)/ml vs [60.21 +/- 27.42] x 10(6)/ml) and sperm viability ([53.93 +/- 13.25]% vs [56.10 +/- 16.58]% vs [51.82 +/- 15.45]%) (P>0.05). The men of the > or = 40 yr group showed a significantly lower percentage of grade a + b sperm ([40.97 +/- 11.91]%) than those of the <35 and 35 - 39 yr groups ([48.47 +/- 11.78]% and [46.84 +/- 13.51]%) (P<0.05), and morphologically normal sperm ([11.76 +/- 5.97]%) than those of the <35 yr group ([15.25 +/- 6.94]% (P<0.05). The rates of fertilization, cleavage, good quality embryo, implantation, clinical pregnancy were 81.52%, 82.61%, 52.33%, 18.06% and 33.33% in the > or = 40 yr group, with no significant differences from those of the <35 yr group (83.18%, 82.68%, 56.99%, 22.40% and 40.00%) and the 35 - 39 yr group (78.78%, 80.66%, 55.01%, 21.74% and 38.96%) (P>0.05), while the abortion rate was markedly increased in the > or = 40 yr group as compared with the <35 yr group (36.36% vs 8.33%, P>0.05).

CONCLUSIONIncreasing male age is related with decreasing percentages of progressively motile sperm and morphologically normal sperm, but not obviously with the rates of fertilization, good quality embryo, implantation, pregnancy and abortion.

It has been suggested that colorectal cancer might not be one homogenous disease entity, based on the distinctive characteristics of its subsite of origin. Incidence data on 4,987 colorectal cancer were obtained from the Seoul Cancer Registry between 1993 and 1995. Age, sex, and subsite-specific incidence rates were compared. The age-standardized annual incidence rates of total colorectal cancer were 26.1 and 18.0 per 100,000 for men and women, respectively. There were no appreciable difference in the rates of colon and rectal cancer for either sex (colon vs rectum: 12.8 vs. 13.2 for men, 9.3 vs. 8.6 for women). The incidence rate of right colon was slightly higher in men than in women, and this discrepancy became even greater in left colon (men vs women: 3.5 vs. 3.0 for right colon, 4.7 vs. 2.9 for left colon). When the incidence rate of right colon was compared with that of left colon, women had a higher rate in the right colon among the elderly, aged 60 yr and over and a lower rate at age 40 yr or less, while the opposite was observed for men. More analytic approaches are needed to identify which factors are related with these descriptive results in colorectal cancer incidence.

Introduction This study aimed to determine the effectiveness of mustard green leaf decoction as an adjunct to drug treatment in controlling blood glucose among Filipinos with type 2 diabetes mellitus.

Methods Participants were randomly assigned to receive mustard decoction or a placebo solution for eight weeks on top of their oral anti-hyperglycemic medication. Fasting blood sugar and complete blood counts were determined at baseline, Week 4 and Week 8, and compared within and across the two groups. 

Results There was a decreasing trend in the blood sugar in the mustard green group while the opposite was noted in the placebo group. The mean FBS levels of the mustard green group were significantly lower than that of the placebo group at the Week 8 determination (6.10 vs 8.69 mmol/L, p=0.0004). The decrease in blood sugar level on the eight week in the mustard green group was significant compared with the baseline level (p=0.008).

Conclusion This study had demonstrated that the intake of Brassica juncea decoction can significantly decrease blood sugar level among type 2 diabetics compared to metformin alone.
