They used steel plates, punches, kicks and everything that came in their hands to beat them up over an argument, reports MidDay. Five cousins Karan, Krupa, Hiral, Miten and Saloni Shah had gone to the restaurant near Vile Parle station around 9.30 pm. An extensive search of the literature was performed in Medline and other available database sources. Karan, Krupa and Hiral are hearing and speaking impaired.They had an argument with one of the waiters following which around 12 waiters from the restaurant got together and started beating them up.
Misdiagnosis is, therefore, probable, thus highlighting the great need for objective and reliable testing.The aim of the present study is to review the current knowledge on the advantages and disadvantages of the new diagnostic methods for Meniere's disease. Controlled clinical studies, prospective cohort studies, retrospective cohort studies, cross-sectional studies, case reports, written guidelines, systematic reviews, and books were selected. The importance of accurate diagnosis for primary healthcare systems and the implications of potential misdiagnoses are also discussed. Later when we got a place, the waiter got angry when Miten asked for two menu cards," said Saloni. The typical clinical triad of symptoms from the vestibular and cochlear systems (recurrent vertigo, fluctuating sensorineural hearing loss and tinnitus) is usually the key for clinical diagnosis.
Glycerol dehydration test and electrocochleography are the main diagnostic tests in current practice, while vestibular evoked myogenic potentials may be used in disease staging.
The key word "Meniere's disease" was considered primary and was either combined to the other key words individually, or used in groups of three. Imagine techniques are not specific enough to set alone the diagnosis of Meniere's disease, although they may be necessary to exclude other pathologies. Information from electronic links and related books were also included in the analysis of data.Four controlled clinical studies, 16 prospective cohort studies, 10 retrospective cohort studies, 1 cross-sectional study, 2 case reports, 1 written guideline, 6 systematic reviews, and 3 books met with the defined criteria and were included in study selection. Meniere's disease is a continuous problem for the patients and affects their quality of life. Taking into account the frequent nature of the disease in certain countries, efforts for reliable diagnosis, prompt referral, and successful management are undoubtedly cost-effective for healthcare systems.


Even our mobile phones have been damaged."The others in the restaurant gathered and stopped the waiters. Hearing loss usually involves the low frequency spectrum, especially in the early stages of the disease.However, physicians may not come across the classic full-blown picture of Meniere's disease from the outset. Various forms of the disease may be encountered in early stages, with symptoms arising either from the vestibular or from the cochlear system.
Around 12.30 am, the police decided to take a rioting case against the waiters and arrested three of them. Hearing loss may be very mild at this stage, and patients may actually not at all complain about it, especially when tinnitus and vertigo prevail.The disease tends to relapse episodically. A full restoration in hearing can be expected to follow an attack of the disease at the initial stages. The "certain" level in the diagnosis is based on post-mortem examination, suggesting that the diagnosis of Meniere's disease relies on probability rather than certainty. This classification was based on the average pure-tone thresholds at 0.5, 1, 2, and 3 kHz, using the worst audiogram of a 6-month interval before treatment [Table 2].
The diagnosis of Meniere's disease in patients with an onset of symptoms after the age of 60 years is very rare. Up to 50% of cases may be bilateral, although the other ear may be affected after several years. This means, in turn, that the cost of treatment, when set against the cost of not treating patients, who, if left untreated, may have up to 20 attacks of long duration per month, and consume much GP and specialist clinic time, undoubtedly favors the efforts toward successful management of the disease, in terms of cost effectiveness.
An autosomal dominant pattern with features that may indicate anticipation is suggested in familial cases. Although an overproduction of the endolymph has been proposed, it seems more probable that a defect in the absorptive activity of the endolymphatic duct and sac is present.
The recurrences may very well be attributed to a subsequent rupture, which may follow healing from previous damage and a symptom-free interval. However, ruptures are not seen in all temporal bones with Meniere's disease, and the entire complex of symptoms cannot be fully explained with this theory. However, establishing the diagnosis of Meniere's disease often takes time because of the nonspecific clinical symptoms in the early stages.The typical clinical triad of symptoms from the vestibular and cochlear systems is usually the key for clinical diagnosis. The duration of acute rotatory vertigo in Meniere's disease usually ranges from 20 minutes to 2 hours. It is rare for the bout to last several hours or even more in the affected individuals.Tinnitus accompanies these episodes and may precede the attacks up to 20 minutes. Aural fullness is also quite characteristic of the disease.The audiometric results vary and depend upon the stage of the disease. They include a low frequency sensorineural hearing loss, although different patterns may also be seen.
Physicians may encounter a conductive hearing loss in very early stages, which may be mistaken as middle ear effusion. However, in later stages, a flat pattern in the audiogram is usually seen and the sensorineural hearing loss may become severe to profound. Glycerol dehydration test and electrocochleography (EcoChG) are the main diagnostic tests for Meniere's disease.The combination of glycerol dehydration test and audiometry has a high sensitivity in the diagnosis of Meniere's disease.
After a baseline audiogram is performed, the patient takes 100 g of 95% glycerol with the same amount of water per os.


The test is considered positive when there is an improvement of 10 db or more in pure-tone thresholds at two or more frequencies, or an improvement of 10% of speech discrimination scores.
In addition, improvements in postural control may also be expected, and have actually been observed in as many as 70% of patients, who are undergoing the test during disease attacks. During the EcoChG, a needle electrode is placed either through the tympanic membrane on the promontory, or on the tympanic membrane, or simply in the ear canal. The components measured are: a) cochlear microphonics, b) summating potentials (SP), and c) action potentials (AP).
The cochlear microphonics and the summating potentials reflect the cochlear bioelectric activity, while the action potentials reflect the activity of distal afferent fibers of the 8th nerve.
Hall and Antonelli reported a sensitivity of 57% and specificity of 94%, [29] while Chung et al. Stimulus onset (on), start of N1 deflection (N1s), end of N1deflection (N1e) and baseline return (bl) are marked. However, after 48 hours, half of the patients with initially abnormal VEMPs may return to normal. Blood tests such as a full blood count, glucose, cholesterol, and thyroid function tests, erythrocyte sedimentation rate, and autoimmune tests [C-reactive protein, immunoglobulins, total complement, antinuclear factor, and anticochlear antibody (anti-68KD)] may be very helpful in order to exclude a metabolic or an immune-mediated disease, especially when the symptoms and signs are bilateral.
A retrospective review of 211 consecutive patients with classic Meniere's disease suggested that treponemal antigen tests for syphilis are cost-effective in evaluating patients with Meniere's disease. However, the extensive testing of glucose metabolism and thyroid function is probably not indicated, at least in patients without a history suggestive of a metabolic disorder.
The results of this test are unfortunately nonspecific for Meniere's disease and may fluctuate over time for a given patient. Nevertheless, caloric testing is also considered cost-effective in evaluating patients with Meniere's disease. This is very important because Meniere's disease may mimic retrocochlear or even central pathologies. In addition, a recent study reported that high-pass noise masking of ABR allows an undermasked wave V to appear in Meniere patients, at latencies similar to those obtained in the unmasked condition, while data from the normal hearing group demonstrate no undermasked wave V (or significantly delayed in latency), due to the masking noise. The distribution of latency differences between groups reportedly contains no overlap, thus providing 100% sensitivity and 100% specificity, and may be used in the differential diagnosis of Meniere's disease and in the monitoring of treatment. 24 hours is the optimal interval between Gd administration and MR examination, when evaluating the whole labyrinthine system.[39] In patients with endolymphatic hydrops, the perilymphatic space surrounding the endolymph is either small or cannot be visualized [Figure 3]. By comparing the perilymphatic VR image (c) and total lymphatic VR image (d), we can appreciate the degree of endolymphatic hydrops three dimensionally (Naganawa S, Nakashima T. Hence, their role in arriving at the decision to consider surgical treatment is still quite limited. However, extensive vestibular testing, in order to determine the residual labyrinthine function of the contralateral ear, should always be exercised, especially when ablative surgical treatment is considered. However, the episodes in the latter case are usually shorter and are also associated with auditory symptoms.ENT specialists, audio-vestibular physicians and neurologists also need to often differentiate Meniere's disease from other pathologies which can cause subjective tinnitus. The typical clinical triad of symptoms from the vestibular and cochlear systems (recurrent vertigo, fluctuating sensorineural hearing loss and tinnitus) is usually the key for clinical diagnosis, even though differential diagnosis is often difficult.
