Lumbar canal stenosis with overactive bladder presenting urinary incontinence developed by walking: a case report

A 74-year-old male complained of lower back pain, paresthesia of the bilateral feet and urinary incontinence. Urinary incontinence manifested at rest and worsened with walking. He had a history of surgery for prostatic cancer. Lumbar magnetic resonance imaging (MRI) demonstrated lumbar canal stenosis at the L4/5 level. The investigations including a cystometrogram manifested an overactive bladder caused by lumbar canal stenosis. His clinical symptoms were unresponsive to conservative treatment and posterior decompression at the L4/5 level was performed surgically to treat lumbar canal stenosis. Postoperatively, his symptoms were relieved. Overactive bladder presenting urinary incontinence that deteriorates with walking due to lumbar canal stenosis is suspected of being caused by circulatory disturbance of the cauda equine or conus medullaris. Emergency treatment including surgery is required for urinary retention in patients with lumbar canal stenosis; however, some degree of urinary disturbance may persist even after prompt and adequate surgery. Overactive bladder such as the present case should be considered as a possible symptom of lumbar canal stenosis, and surgical treatment for lumbar canal stenosis may be considered in the 'overactive bladder' stage before urinary retention begins, if the patient does not respond to conservative treatment.     

Study profile on baseline survey of Daiko Study in the Japan Multi-Institutional Collaborative Cohort Study (J-MICC Study)

The Japan Multi-Institutional Collaborative Cohort Study (J-MICC Study) is a long-term cohort study to investigate the interactions among genotypes, lifestyles, and lifestyle-related diseases, especially cancer. This article reports the outline of the baseline survey of the Daiko Study, one site of the J-MICC Study. That survey was conducted between June 9, 2008 and May 31, 2010 at the Daiko Medical Center of Nagoya University in Nagoya, Japan. Subjects were registered residents of Nagoya City aged 35 to 69 years who had not participated in other J-MICC sites. Recruitment was mainly announced through leaflets distributed in mailboxes citywide, personal communications, and regional information, such as posters in public or commercial facilities. Participants provided blood plasma, serum, buffy coat, urine, and data on health check-ups. They also completed a self-reported questionnaire on lifestyle, disease history, family history, and for women, reproductive history. As of the end of September 2010, 4 out of 5172 registered participants had withdrawn from the study, leaving data from 5168 participants (1467 males and 3701 females) available for analysis. Mean age +/- standard deviation (SD) was 52.5 +/- 10.3 years. Current smokers accounted for 24.1% (n=354) of males and 6.9% (n=256) of females. Current drinkers included 74.9% (n=1099) of males and 45.9% (n=1699) of females. Lifestyle data and specimens were successfully collected to examine any associations among disease biomarkers, lifestyles, and genotypes.     

Emotion with tears decreases allergic responses to latex in atopic eczema patients with latex allergy

OBJECTIVE: Allergic responses are enhanced by stress, whereas they are reduced by laughter in atopic eczema patients. Emotion with tears decreases plasma IL-6 levels in patients with rheumatoid arthritis. Thus, the effect of emotion with tears on allergic responses in patients with atopic eczema was studied. METHODS: Sixty patients with atopic eczema having latex allergy viewed both the weather information video and the heart-warming movie, Kramer vs. Kramer. Just before and immediately after viewing each video, allergic responses to latex were measured. RESULTS: Viewing the weather information video did not cause emotion with tears in any patients, and it failed to modulate allergic responses. In contrast, viewing Kramer vs. Kramer caused emotion with tears in 44 of 60 patients, and it reduced allergic skin wheal responses to latex and latex-specific IgE production in them. CONCLUSION: Emotion with tears reduced allergic responses, and it may be useful in the treatment of allergic diseases.     

Heparan sulfate 6-O-sulfotransferase 1, a gene involved in extracellular sugar modifications, is mutated in patients with idiopathic hypogonadotrophic hypogonadism

Neuronal development is the result of a multitude of neural migrations, which require extensive cell-cell communication. These processes are modulated by extracellular matrix components, such as heparan sulfate (HS) polysaccharides. HS is molecularly complex as a result of nonrandom modifications of the sugar moieties, including sulfations in specific positions. We report here mutations in HS 6-O-sulfotransferase 1 (HS6ST1) in families with idiopathic hypogonadotropic hypogonadism (IHH). IHH manifests as incomplete or absent puberty and infertility as a result of defects in gonadotropin-releasing hormone neuron development or function. IHH-associated HS6ST1 mutations display reduced activity in vitro and in vivo, suggesting that HS6ST1 and the complex modifications of extracellular sugars are critical for normal development in humans. Genetic experiments in Caenorhabditis elegans reveal that HS cell-specifically regulates neural branching in vivo in concert with other IHH-associated genes, including kal-1, the FGF receptor, and FGF. These findings are consistent with a model in which KAL1 can act as a modulatory coligand with FGF to activate the FGF receptor in an HS-dependent manner.     

New application of the gluteal-fold flap for the treatment of anorectal stricture

Purpose

Total intersphincteric resection (total ISR) is a surgical option for patients with advanced cancer of the lower rectum. However, anorectal stricture can develop after total ISR, which stretches from the anus to the lower rectum. Conventional anoplasty for anal stricture is often ineffective for them because the areas of stricture are long and the most proximal points of the strictures are too far for advancement flaps or rotation flaps to reach. We have developed a new surgical treatment method using a gluteal-fold flap (GFF) for anal stricture after total ISR.

Methods

From April 2004 through June 2007, hemilateral GFFs were transferred to treat anorectal strictures after total ISR in three patients at the National Cancer Center Hospital East, Chiba, Japan. Postoperative results and anal function were evaluated.

Results

In all three patients, GFFs were successfully transferred, and good dilation of the anorectal stenosis was achieved. Postoperative anal function was satisfactory.

Conclusion

The GFF has a rich vascular supply and can be simply and reliably transferred. We believe that GFF transfer is an excellent option for treating anorectal strictures after total ISR.     

Interferon-alpha treatment for severe atopic dermatitis

Patients with both severe atopic dermatitis (AD) and chronic myeloid leukemia, chronic hepatitis B, or chronic hepatitis C were treated with interferon-alpha (IFN-α). IFN-α treatment improved AD. Moreover, there were also significant decreases in serum IgE and IgG4 levels and in in vitro spontaneous IgE and IgG4 production by patients' mononuclear cells.     

A very rare case of breast cancer in a female-to-male transsexual

The incidence of breast cancer in female-to-male (FTM) transsexuals who received mastectomy and sex reassignment surgery is very rare. In fact, there is only one previous medical report of such a case. We experienced a case of an FTM transsexual who developed breast cancer 12 years after mastectomy and hysterectomy with bilateral salpingo-oophorectomy. Because he had been continuously receiving testosterone during the last 15 years and because histopathological examination revealed positive estrogen receptor and androgen receptor expression, we suggest that exogenous testosterone may have initiated the development of breast cancer via two distinct pathways. We describe the clinical course and condition of the patient and recommend that medical personnel consider the possibility of hormone-related cancer in FTM transsexuals receiving cross-sex hormones.
