[Two cases of amylase-producing lung cancer].

In 1951, Weiss et al. first reported a case of an amylase-producing lung cancer. Since then, reports on immunohistochemical, ultrastructural, and biochemical studies have been published. We recently have experienced two autopsy cases of lung cancer that manifested high amylase activity in the serum, urine, and pleural effusions. Histologically, both lung cancers were classified as being well differentiated adenocarcinomas, and immunohistochemically, the tumor cells showed positive immunoreactivity for amylase. This paper discusses the histogenesis of amylase-producing lung cancers and cases found in the literature.

Cervico-vestibular interaction in eye movements.

The cervico-vestibular interaction was investigated in normal subjects and patients with unilateral labyrinthine dysfunction using neck vibratory stimulation and caloric stimulation. There is a functional interaction between sensory inputs from the neck proprioceptors and the peripheral labyrinth in the patients with unilateral labyrinthine dysfunction. However, this interaction was not observed in normal subjects. This result indicates that the role of the cervical sensory inputs in normal subjects and the patients is different. That is, inputs from the neck proprioceptors have little effect on the control of eye movements in normal subjects, whereas the neck inputs are quite important for the control of eye movements in patients with unilateral labyrinthine dysfunction.

The presence of Theileria sergenti in Haemaphysalis longicornis overwintering in pasture in Japan.

Unfed Haemaphysalis longicornis ticks were collected from the soil of pasture during the winter and their salivary glands were examined by the methyl green pyronin staining method in order to detect overwintering of Theileria sergenti, the causative agent of bovine theileriosis in Japan. A transmission experiment was carried out using these ticks applied to a splenectomized calf. The protozoa which appeared in the peripheral blood were identified parasitologically and seroimmunologically as T. sergenti. The results suggested that T. sergenti in Japan might overwinter in H. longicornis which moulted after repletion on infected cattle in the autumn and hid in the soil during the winter. Moreover, it seemed possible that T. sergenti might develop to the infective stage in H. longicornis during the overwintering period.

[Comparative study on cefmetazole and cefazolin in the treatment of suppurative otitis media].

Cefmetazole (CMZ) was compared to cefazolin (CEZ) for efficacy and safety in the treatment of suppurative otitis media (including acute otitis media and chronic otitis media in acute aggravating stage) under well controlled clinical trials. The therapeutic effects were analyzed statistically in 172 patients (82 administered CMZ, 90 administered CEZ). The adverse reactions were also analyzed statistically in 199 patients (CMZ 99, CEZ 100) in whom the judgement was possible. 1. The efficacy rate of CMZ (72.3% for good to excellent response) was assessed by physicians in charge to be similar to that of CEZ (59.3%). This was the same being assessed by the committee, too (CMZ 64.6%, CEZ 56.7%). 2. When patients were classified into 2 groups (acute otitis media, chronic otitis media in acute aggravating stage) with respect to diagnosis, statistically significant difference in clinical efficacy assessed by physicians in charge was observed in the cases with chronic otitis media (CMZ, CEZ). In addition, the improvements of flares on the drum membrane and the mucous membrane of eardrum were significantly better in the CMZ group than in the CEZ group. 3. Bacteriologically, 16 cases (19.8%) of S. aureus were resistant to CEZ, while only 1 case (1.2%) to CMZ. CMZ was judged to be effective in 5 of the 6 cases in which CEZ-resistant strains were detected. 4. Side effects were found in 2 cases (2.0%) treated with CMZ: one complained of retching and abdominal pain and the other developed skin eruption. On the other hand, only 1 case (1.0%) developed skin eruption in the CEZ group. These results suggest that CMZ is a new antibiotic agent which is highly valuable in the treatment of suppurative otitis media.

[Clinical observations of tuberculous infection of the middle ear].

Since fifty years, three main infection routes of otitis media tuberculosa have been advocated by the literature. In childhood it was considered to be limited to haematogenic or primary infection, because the tuberculous focus was not found in the lung or in other parts of the body. Two own observations of children with tuberculosis of the middle ear were reported by the authors. Histological examination of the granulation tissue, taken from the mastoid cavities, showed Langhans cells. Also tuberculosis was verified by microbiological examination. When adenotomy was performed one month after the ear operation, also the adenoid tissues showed typical tuberculosis. The authors suggest the possibility of tubal infections from the adenoid tissue into the middle ear.

A new neurotological test for detecting cerebellar dysfunction.

The adaptation of the vestibulo-ocular reflex (VOR) was studied in 26 normal subjects and 26 patients with cerebellar lesions, using horizontal vision-reversal prisms. In normal subjects, the adaptation of gain after wearing prisms for one hour was approximately 50% of the VOR value in the dark. In contrast to this, patients with cerebellar lesions showed less adaptation--approximately 20% after a one-hour forced adaptation task. These were type A, higher gain in the initial level and abnormal adaptation (10 cases); type B, higher gain in the initial level and normal adaptation (5 cases); and type C, normal initial level and abnormal adaptation (11 cases). The cases showing the typical type-A responses tended to have severe widespread or midline lesions of the cerebellum. Typical type-B cases had mild cerebellar lesions, and typical type-C cases tended to have lesions restricted to one side of the cerebellum. From these results, it can be speculated that reduction of VOR adaptation occurs when one side of the cerebellum has severe lesions, but it is sufficient to produce a normal vestibulo-ocular reflex if at least half of the cerebellum is intact.
