[Laryngeal Atypical Carcinoid Combined with Squamous Cell Carcinoma: A Case Report].

The primary laryngeal atypical carcinoid is relatively rare, and the tumor combined with other histologic types including squamous cell carcinoma is extremely rare. We experienced a case which was complicated with atypical carcinoid and squamous cell carcinoma. A 79 years old man complaining of sputum was admitted to Hiroshima City Hospital.

Novel and simple prognostic index for nasal natural killer/T-cell lymphoma.

Background: Few studies have investigated the prognostic factors for nasal natural killer (NK)/T-cell lymphoma.

Methods: This was a retrospective multicenter clinical study. The clinical records of 36 patients with nasal NK/T-cell lymphoma who had been first treated between 1996 and 2011 were collected from 12 hospitals.

Hearing immaturity found by ABR and its clinical impact on otoneurological evaluation.

Auditory Brainstem Response (ABR) is the most reliable and most frequently used procedure to evaluate audiological conditions in early infancy. However, several reports have demonstrated that developmental change in the central nervous system may affect the results of ABR in audiological evaluations. We examined statistically the reliability of ABR for the diagnosis of profound deafness in early childhood according to our experience over the past 12 years of follow-up in our facility.

Evaluation of facial palsy by moiré topography index.

We investigated the usefulness of moiré topography for evaluating facial nerve function in 51 patients with facial palsy and 10 normal volunteers. This method visualizes the shape of objects in three dimensions. We devised three moiré indexes as a simple method of quantifying the severity of facial palsy: the nasolabial groove moiré index, the oral angle moiré index, and the inner canthus moiré index.

Effect of and indication for tonsillectomy in IgA nephropathy.

Although more than 20 years have passed since the initial report of IgA nephropathy, the etiology of this disease is still unclear. Some reports suggest that the tonsil is an important etiological factor. We performed tonsillectomy on 26 patients with IgA nephropathy associated with chronic tonsillitis, and followed up the patients for two years after the operation to evaluate its clinical effect on this disease.

[Quantitative assessment of facial palsy by Moiré topography].

It is essential to establish an objective and quantitative method for evaluating facial palsy and to measure the extent of paralysis in order to evaluate therapeutic efficacy, determine prognosis, select appropriate treatment and observe the process of recovery. This study utilized Moiré topography, which displays three-dimensional facial symmetry with high precision and is based on light interference theory, to determine the extent of facial palsy in 38 patients (20 men and 18 women) 5 months to 73 years of age. A stereoscopic lattice type Moiré camera (FM3013) was connected to a CCD camera and to the monitoring device for confirming Moiré stripes.

[Microvascular architecture of the human tongue carcinoma--a scanning electron microscopic study].

Vascular architecture of tumors in experimental animals has been studied in detail. However, the reports on architecture of the capillaries in human carcinoma in the head and neck regions are few nowadays. In this paper architecture of the blood vessels reproduced by using methacrylate casting medium in human carcinoma of the tongue was studied by scanning electron microscopy.

Temporal bone histopathology in trisomy 18 syndrome: a report of two cases.

Temporal bone histopathological findings of two patients with trisomy 18 syndrome are described. Many of the abnormalities previously described were seen in the present cases; namely, atresia of the external auditory canal, aberrant course of the tensor tympani muscle, malformed stapes, aberrant course of the facial nerve with an obtuse angulation at the first genu and displacement of geniculate ganglion cells into the internal auditory canal, shortened cochlea with decreased spiral ganglion cell population, and vestibular anomalies, such as bony and membranous blockage of the superior semicircular canal. Moreover, an extremely underdeveloped malleus and incus continuous with a persistent Meckel's cartilage were observed.

Temporal bone pathology in congenital anomalies of the oval window and the facial nerve.

Temporal bones of six infants with congenital ear anomalies were examined for abnormalities of the oval window and facial nerve. These temporal bones were classified into two groups according to the degree of malformation: group A, those with atresia or absence of the oval window; and, group B, those with hypoplasia of the stapes and annular ligament. Group A, consisting of five ears, were associated with severe middle ear anomalies such as the abnormal course of the facial nerve and absence of the stapes.

Fibrinolytic activity of middle ear fluid in otitis media with effusion.

In order to investigate the prolonged factors of otitis media with effusion, hydrolytic activities for specific substrates of plasmin and plasminogen activator (P.G.-activator) and the activity for fibrin degradation (fibrinolysis) were measured.

A case of monostotic fibrous dysplasia of the temporal bone associated with epileptic seizure.

An 11-year-old male with monostotic fibrous dysplasia of the left temporal bone was reported. At the age of seven years, the patient began having epileptic attacks, and a bony swelling of the left temporal region was noticed by his mother. Roentgenologically, there were almost thorough osseous obstruction and osseous proliferation of the external auditory canal and pars petrosa, respectively.
