CT signs of pressure induced expansion of paranasal sinus structures

Published on: 26th September, 2017

OCLC Number/Unique Identifier: 7317653929

Several articles have been written about hyper inflated sinus structures. Never before, however, a complete overview of all possible pressure induced variations of sinus anatomy have been published. The aim of this study was to make an inventory of the most common CT signs of hyper inflated paranasal sinus structures. During a period of 2 years all CT-scans of the paranasal sinuses made in an ENT-department were studied and the most typical shapes of hyper inflated sinus structures were recorded. The authors documented 9 different anomalies of the anterior paranasal sinus complex (frontal sinus, frontal and supra-orbital recess and anterior ethmoid), 8 of the ethmoid and 1 of the sphenoidal sinus. These hyper inflated paranasal sinus structures can only be generated by high positive intranasal pressures. The nose blowing manoeuvre is the only manoeuvre that generates extremely high pressures and as such it might be the driving force in the generation of these hyper inflated paranasal structures and consequently play a role in the pathophysiology of chronic sinusitis. Pneumatisation of the sinuses starts at birth and is a lifelong process. Sometimes, however, pneumatisation can be extreme and will result in facial deformities. Pneumosinus dilatans, is such a condition, characterized by an abnormal dilatation of a paranasal sinus cavity, containing air only. Most reports describe pneumosinus dilatans of the frontal sinus, but also other sinuses can show this phenomenon: maxillary sinus and in one case a unilateral pneumosinus dilatans of nearly all sinuses (maxillary, ethmoid, and sphenoid sinus) was described. Recently Kalavagunta et al., described a less dramatic expansion of the maxillary sinus and named it “Extensive Maxillary Sinus Pneumatisation” (EMSP). They were surprised to see that EMSP has received little attention in the literature. Neuner et al., described 9 different atypical pneumatisation abnormalities of the paranasal sinus anatomy. Most of deformities of the sinus pneumatisation are growth deformities of the thick bones that make up the frame of the sinuses. Only a few articles, deal with specific deformities of thinner bone structures such as “wavy orbital floor” and “frontal cells”. Never before, however, an article was published that studied all possible deformities due to increased pressures and tried to make a classification. So the aim of this study was to make an inventory of the most obvious pressures related deformities that can be seen on CT-scans of patients with rhinosinusitis.

Cognition and Memory Impairment among Patients of Depression in Pakistan-The Role of Conventional and Newer Anti-Depressants

Published on: 17th July, 2019

OCLC Number/Unique Identifier: 8200138649

Background: Antidepressant therapy is the most adopted treatment option for depression. The evaluation of cognitive effects related to antidepressant drug use is important for better selection of antidepressant drugs that leads to improved cognitive performance and patient health related quality of life. Aim: The aim of the present study was to evaluate the effects of antidepressant drugs on cognition and memory among patients of depression in Pakistan. Method: A descriptive cross-sectional study design was used. A pre-validated data collection tool Mini Mental State Examination was used. The sample size was calculated to be 382 with 95% confidence interval and 5% level of error. The data was cleaned, coded and analyzed statistically using spss 21. Chi-Square test (p ≥ 0.05) was used to find association among different variables. Results: The results showed that out of 382 respondents, 7.3% (n=28) were being prescribed amytryptyline and among them 46% (n=13) had questionably significant cognitive impairment and 53% (n=15) had mild cognitive impairment. On the other hand out of 23% (n=89) patients on escitalopram monotherapy, 85% (n=76) had impairment of questionably significant impairment and only 13.4% (n=12) had mild impairment. Area of residence and medication therapy were significant variables (p<0.05) that can affect cognition and memory among patients of depression. Conclusion: The results of present study concluded cognitive impairment of questionably significant nature among patients of depression in Pakistan. For the better management of depression, it is recommended that anti-depressant drug therapy should be tailored according to individual patient requirements.

Ocular changes and disorders associated with Obesity

Published on: 27th July, 2018

OCLC Number/Unique Identifier: 7795938194

Obesity is a chronic and metabolic disease with a high increasing prevalence worldwide. It has multifactorial pathogenesis including genetic and behavioral factors [1-5]. Overweight and obesity have been defined and classified by the World Health Organization (WHO) and the National Institutes of Health (NIH) [2,3]. A person with a normal weight has Body Mass Index (BMI) of 18.5-24.9. A person with a BMI under 18.5 is called underweight. An adult having a BMI of 25-29.9 is overweight and pre-obese. Class 1 obesity is defined as a BMI between 30.00-34.99. Class 2 (Severe) Obesity is to have a BMI between 35.00-39.99. Morbid (Extreme, Class 3) obesity is to have a BMI over 40 [1-5]. Obesity is significantly associated with enhanced morbidity and mortality rates. It has also various economic, medical and psychological effects and causes health problems including many systemic diseases, economic costs and burdens, social and occupational stigmatization and discrimination and productivity loss [4-6]. Obesity carries the increased risk of development of many systemic and chronic diseases, including sleep apnea, depression, insulin resistance, Type 2 (adult-onset) diabetes, Gout and related arthritis, degenerative arthritis, hypertension, dyslipidemia, heart disease such as myocardial infarction, congestive heart failure, or coronary artery disease, polycystic ovary syndrome and reproductive disorders, Pickwickian syndrome (obesity, red face and hypoventilation), metabolic syndrome, non-alcoholic fatty liver disease, cholecystitis, cerebrovascular accident, colonic and renal cancer, rectal and prostatic cancer in males, and gallbladder, uterus and breast cancer in females [6-12]. In recent years, some publications reported that obesity has been strongly associated with some ocular diseases including age-related cataract and maculopathy, glaucoma, and diabetic retinopathy [13-16]. The recent reports demonstrated that the central corneal thickness and intraocular pressure were increased while as mean thickness of RNFL and retinal ganglion cell and choroidal thickness (CT) were decreased in the morbidly obese subjects [17-19]. However, another study has reported that CT increased in obese children [20]. On the other hand, a recent study reported that all values of the specific tests used to evaluate the ocular surface were within the normal range [21]. In some experimental studies, it has been demonstrated that obesity may cause retinal degeneration [22,23]. Additionally, in a past meeting presentation, it has been speculated that keratoconus is associated with severe obesity [24]. Teorically, idiopathic intracranial hypertension, and papilledema may also be associated with obesity [25]. Obesity may be also a cause of mechanical eyelid abnormalities such as entropion [26]. However, further investigations are needed to detect the significant relationship between these diseases and obesity. On the other hand, the ocular surgeries of obese patients are difficult compared to normal weight-subjects. The posterior capsule rupture and vitreous loss may easily develop during cataract surgery of these patients because obese patients have an elevated vitreous pressure and operating table cannot often be lowered or surgeon’s chair cannot be elevated sufficiently to provide the clear viewing of the operating area and tissues. So, some different surgical manipulations such as standing phacoemulsification technique and reverse Trendelenburg position have been developed. Additionally, the standing vitrectomy technique has been used for vitreoretinal interventions in morbidly obese patients [27,28]. In conclusion, all obese subjects should be subjected to a completed ophthalmological examination and to relevant clinics for the detection of possible comorbidities and diseases

Kikuchi’s disease in a young Scandinavian woman

Published on: 20th September, 2017

OCLC Number/Unique Identifier: 7317601184

A 21 year-old woman presented with cervical lymphadenopathy and night sweats. Initially, lymphoma was suspected and one of the enlarged lymph nodes was excised in order to make a diagnosis. Histopathological examination revealed Kikuchi’s disease, which is usually a benign syndrome with spontaneous resolution. The disease is very rare, particularly in Caucasian populations. A higher incidence is seen in patients of Asian descent. The patient had persistent swelling of cervical lymph nodes over several months and further lymph nodes were removed as malignant transformation was suspected. However examinations showed only Kikuchi’s disease. There was given no specific treatment. Follow-up appointments were performed biannually and the patient is currently awaiting removal of yet another swollen lymph node on suspicion of relapse of her Kikuchi’s disease.

Diseases of the mental sphere revealed by the psychiatrist at contingent of patients of the consultative outpatient admission

Published on: 9th July, 2019

Introduction: The problem of protecting and strengthening the mental health of the population is the most important task of ensuring the socio-economic well-being of the Komi Republic (RK) as an integral part of the Russian Federation (RF), since it is a key resource for the development of a subarctic region. The aim of the work: was to characterize diseases of the mental sphere revealed by the psychiatrist at contingent of patients of the consultative outpatient admission at the 1State Autonomous Health Agency of the Republic of Komi “Consultative and Diagnostic Center of the Republic of Komi” (SAHA RK “CDC”) of the subarctic territory. Materials and methods: The analysis of a continuous sample of 6255 patients of the psychiatrist of the consultative department in 2015-2017 was carried out. on the basis of medical records. Analysis methods included: analytical and statistical. The control group consisted of a continuous sample of 5,356 psychiatric patients in 2010–2012. The depth of the study was 8 years. Discussion: Trends in changes in demographic indicators, including gender and age, in the structure of patients of a psychiatrist in an outpatient consultative procedure are considered. Indicators of the identified pathology of the mental sphere, including the first identified and pathology in patients suffering from epilepsy in comparison with the control group are given. Attention is paid to the organizational and methodological work of an outpatient counseling psychiatrist on the targeted identification by internists of signs of mental pathology in patients referred to a diagnostic center with somatic diseases. Priorities for the improvement of specialized advisory (including psychiatric) assistance to the population of the RK and ensuring its quality were identified. Conclusions: 1. The psychiatrist of the advisory department in 2015-2017. 6255 people were accepted (889 more than in the control group of 2010-2012). The increase was 16.78%. Primary patients account for 64.38% of the total number of people who applied to a psychiatrist (4027 people). 2. In the structure of the psychiatric pathology of the outpatient psychiatric appointment, the proportion of organic, including symptomatic, mental disorders (F00-F09) is 47.9±0.6%; neurotic, stress-related and somatoform disorders (F40-F49) - 39.6±0.6%; mental and behavioral disorders associated with the use of psychoactive substances (F10-F19) - 3.5±0.2%; mood disorders (affective disorders) (F30-F39) - 2.8±0.2%. 3. The most frequently detected pathologies in patients with epilepsy are: 1) Mild cognitive impairment; 2) Personality disorders; 3) Organic emotionally labile (asthenic) disorders. Their share annually accounts for 71.5%-75.8% of all types of nosological forms. The fourth and fifth ranking places are taken by: 4) Organic anxiety disorders; 5) Non-psychotic depressive disorders. Rarely diagnoses are established: “Organic Amnesia Syndrome” and “Dementia”. 4. Organic, including symptomatic, mental disorders prevail in the structure of newly discovered mental disorders; neurotic, stress-related and somatoform disorders (up to 87.7%). Mental and behavioral disorders associated with the use of psychoactive substances and mood disorders (affective disorders) do not exceed 8.4%.

Low vision due to persistent Cloquet’s canal

Published on: 26th June, 2018

OCLC Number/Unique Identifier: 7795965841

The Cloquet’s canal (CC) is the remnant of the primary vitreous and it disappears in the intrauterine developmental period of an eye. Rarely it can persist in mature eyes and cause low visual acuity. We detected a persistent CC and low visual acuity in a 36 year-old patient. Fundus fluorescein angiography and optical coherence tomography examinations were completely normal in our case and low visual acuity was directly associated with opacification of the fibrovascular persistent CC tissue. Persistent CC can cause low visual acuity due to directly media opacity effect of fibrovascular tissue without any complication.

Impedance audiometry: Stapedial reflex eliciting conditions

Published on: 20th September, 2017

OCLC Number/Unique Identifier: 7317656261

The work is an attempt to create a complete system of conditions which influence genesis, existence, and response characteristics of stapedial reflex in impedance audiometry. The author divides the conditions into the internal-reflex arc integrity, temporal acoustic summation, mixed-external auditory meatus and middle ear, and internal-side of stimulation and energy content of the stimulus. The system of conditions that influence stapedial reflex is based on a criterion, that stapedial reflex depends on energy, which is percepted by the inner ear as subjective loudness. The system of conditions stated in this work is based mainly on the author’s own experiments and measurements, which are herein also documented. At the same time, these results are in accordance with data in literature as quoted. This system is not closed-it potentially may be completed using the basic criterion and further knowledge.

Tinnitus: Diagnosis and treatment options

Published on: 31st August, 2017

OCLC Number/Unique Identifier: 7317598632

Tinnitus-derived from the Latin “tinnire” meaning “to ring” is a perceived ringing, buzzing, or hissing in the ear(s) or around the head-which has multiple etiologies and is sometimes idiopathic. As of 2009 in the United States, approximately 50 million Americans were affected for six months or greater, while a United Kingdom study in 2000 reported a 10% prevalence in the adult population [1]. Tinnitus may vary widely with regard to pitch, loudness, description of sound, special localization, and temporal pattern [2]. Most often, tinnitus is associated with other aural symptoms, such as hearing loss and hyperacusis [3]. Tinnitus may result in sleep disturbances, work impairments, and distress. The severity varies within this cohort of chronic sufferers, with some unable to fulfill daily activities. Though tinnitus is more likely to affect adults and the incidence increases with age, children can experience tinnitus as well [4]. Males are more likely to suffer as are individuals who smoke [5].

Treatment of Retinal Pigment Epithelial Detachment

Published on: 23rd March, 2018

OCLC Number/Unique Identifier: 7795943479

Anatomical separation of the retinal pigment epithelium from the Bruch membrane is defined as retinal pigment epithelial detachment (PED) andit is classified as drusenoid, serous, and vascularized. Vascularized PED is mostly associated with choroidal neovascularmembrane due to age-related macular degeneration and the risk of vision loss is high in this situation. Studies show that all of baseline values including BCVA, PED height, subretinal fluid, central macular thickness, PED volume, vertical dimension, presence of coincident macular pathology, reflectivity and morphology on optical coherence tomography have prognostic importance. Current treatment protocols mainly based on intravitreal injection of anti-vascular endothelial growth factor (VEGF).Even the bevacizumab was the first anti-VEGF that was used for treatment in PED, there are several reports show the insufficiency of bevacizumab. In treatment-naïve eyes, both of ranibizumab and aflibercepthave similar effect in vascularized PED. In treatment-resistant eyes, high dose bevacizumab or switching therapy of anti-VEGF procedures can be effective when considering of all cases, aflibercept seems more effective than other options.We aimed in this manuscript, to give a general information about different characteristics of PEDs and to investigate the treatment strategies in the light of current literature.

Place of beta-radiation in the etiology and treatment of cataract

Published on: 9th February, 2018

OCLC Number/Unique Identifier: 7355970716

Among eye diseases, cataract is the most commonly encountered lens disease and the leading cause of reduced vision. Cataract caused by radiation develops due to neck & head, central nervous system tumors, eye localized tumors and total body irradiation. Today, the only treatment of cataract is surgery. Beta radiation is seen to have an important place both in the etiology and treatment of cataract. Beta-radiation creates cataract in the lens as an adverse effect. However, beta radiation implementation is used for delay or prevention of cataract in glaucoma surgery. Effects of beta-radiation on the etiology and treatment should be supported by further prospective clinical studies.
