Background and Objectives Pilomatricoma is a frequently diagnosed skin lesion of the head and neck that may often be misdiagnosed as other skin lesions. This study evaluated whether ultrasonography (USG) or computed tomography (CT) is the most helpful imaging modality for the accurate preoperative diagnosis of pilomatricoma in head and neck regions of children and adolescents.Subjects and Method A retrospective review was conducted for 59 patients with pilomatricoma under the age of 19 years. All cases were pathologically confirmed with pilomatricoma in the head or neck.Results Preoperative imaging examinations were performed with USG in six cases and with CT in nine cases. The accuracy of preoperative diagnosis was compared between three groups: 1) with clinical findings only, 2) with USG, and 3) with CT. The correct preoperative diagnosis was made in 18 (30.5%) of the total of 59 cases. Using only clinical findings, 10 (22.7%) out of 44 patients were diagnosed as pilomatricoma. With the addition of USG, pilomatricoma was diagnosed in 1 (16.7%) out of six cases, whereas with the addition of CT, 7 (77.8%) out of 9 cases (77.8%) were diagnosed correctly. Preoperative diagnosis of pilomatricoma with CT imaging was more accurate than clinical findings only (vs. CT; odds ratio [OR]=11.900, 95% confidence interval [CI] 2.126-66.615; p=0.001) or USG (vs. CT; OR=17.500, 95% CI 1.223-250.357; p=0.020).Conclusion In the preoperative diagnosis of pilomatricoma, imaging modalities such as CT and USG are helpful, with CT offering higher diagnostic accuracy and USG procedural benefits in younger children.

Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, was published in November 2000 and contains major changes from its predecessor. In the Fourth Edition, all musculoskeletal evaluation and rating was described in a single chapter. In the Fifth Edition, this information has been divided into three separate chapters: Upper Extremity (13), Lower Extremity (14), and Spine (15). This article discusses changes in the spine chapter. The Models for rating spinal impairment now are called Methods. The AMA Guides, Fifth Edition, has reverted to standard terminology for spinal regions in the Diagnosis-related estimates (DRE) Method, and both it and the Range of Motion (ROM) Method now reference cervical, thoracic, and lumbar. Also, the language requiring the use of the DRE, rather than the ROM Method has been strengthened. The biggest change in the DRE Method is that evaluation should include the treatment results. Unfortunately, the Fourth Edition's philosophy regarding when and how to rate impairment using the DRE Model led to a number of problems, including the same rating of all patients with radiculopathy despite some true differences in outcomes. The term differentiator was abandoned and replaced with clinical findings. Significant changes were made in evaluation of patients with spinal cord injuries, and evaluators should become familiar with these and other changes in the Fifth Edition.

Background: Scabies is a skin disease caused by an obligate human parasite mite Sarcoptes scabiei var. hominis. Children under the age of two and elderly individuals are at the greatest risk. Knowledge of this condition is important for an early diagnosis to be made and treatment to be initiated. Objective: The review aimed to familiarize physicians with the clinical manifestations, diagnosis, evaluation, and management of scabies. Methods: A search was conducted using Pubmed with the built-in "Clinical Queries" tool. The search term "Scabies" was used. The categories of "epidemiology", "diagnosis", "therapy", "prevention" and "prognosis" had a limited scope for primary clinical studies. Meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews were included. Only papers published in the English language were included. A descriptive, narrative synthesis was provided of the retrieved articles. Results: Worldwide, scabies affects 200 to 300 million individuals annually. The average prevalence is estimated to be 5 to 10% in children of developing countries. Transmission usually occurs after close prolonged skin-to-skin contact. Classic scabies is characterized by an erythematous papular eruption, serpiginous burrows, and intense pruritus. Sites of predilection include the webs of the fingers, volar wrists, lateral aspects of fingers, extensor surfaces of elbows and knees, waist, navel, abdomen, buttocks, groins, and, genitals. A clinical diagnosis of classic scabies can be made on the basis of the history and clinical findings. Other clinical variants include crusted scabies, nodular scabies, and bullous scabies. Finding the mite, ova, or fecal pellets on microscopic examination of scrapings taken from skin lesions confirms the diagnosis of scabies infestation. For eradication of scabies mites, the drugs of choice are topical permethrin and oral ivermectin. Conclusion: Scabies is a highly contagious parasitic cutaneous disease that is stigmatising and debilitating. Increased awareness, accurate diagnosis, and prompt treatment are essential for the effective control of scabies and for the prevention of the spread of the disease.

AbstractIn 2021, the German Society of Otorhinolaryngology, Head and Neck Surgery is celebrating the 100th anniversary of its foundation. The aim of this article is to present the main inventions and progress made in Germany before 1921, the date the society was founded. Three chronological periods are discernible: the history of otorhinolaryngology (ORL) in Germany until the beginning of the 19th century, focusing mainly on the development of scattered knowledge; the birth of the sub-specialties otology, laryngology (pharyngo-laryngology and endoscopy), and rhinology in the 19th century, combining advances in knowledge and implementation of academic structures; and the creation of the ORL specialty at the turn of the 20th century, mainly concentrating on academic organization and expansion. This period was crucial and allowed for the foundation of the German Society of Otorhinolaryngology, Head and Neck Surgery on solid ground. Germany played an important role in the development and progress of ORL internationally in the 19th century with such great contributors as Anton von Tröltsch, Hermann Schwartze, Otto Körner, Rudolf Voltolini, and Gustav Killian to mention a few.

Background Subtotal cholecystectomy is a “damage control” or “bailout procedure” that is used in difficult gallbladder cases when severe inflammation distorts the local anatomy resulting in increased risk in damage to surrounding structures. Subtotal cholecystectomy rates increased nationally over the past decade. We aimed to determine provider experience and patient factors associated with the performance of subtotal cholecystectomies. Methods All cholecystectomies from 2016 to 2019 were reviewed. Patient demographics, laboratory values, imaging, preoperative diagnosis, surgical technique (fenestrating vs. reconstituting), and years of attending and resident experience were collected. Multivariable regression analysis was performed to evaluate for factors that increase the likelihood of subtotal cholecystectomy. Results Of 916 cholecystectomies, 86 were subtotal. The likelihood of subtotal cholecystectomy did not increase based on attending experience of ≤5 vs. > 5 years (odds ratio (OR) .66, P = .09). Older age (adjusted odds ratio (aOR) 1.23, P = .03), male sex (aOR 2.59, P < .01), white blood cells (WBC) above 10.3 (aOR 2.02, P = .02), and preoperative diagnosis of acute on chronic cholecystitis (aOR 5.47, P < .01) were associated with increased likelihood of subtotal cholecystectomy. Discussion Older age, male sex, WBC above 10.3, and preoperative diagnosis of acute on chronic cholecystitis were associated with the increased likelihood of subtotal cholecystectomies. The performance of subtotal cholecystectomy was not impacted by attending years of experience. In cases of severe gallbladder pathology, this technique is being used as an operative strategy among all surgeon levels.

Nocardiosis is known to be an opportunistic infection most commonly affecting immunocompromised patients that can lead to life-threatening conditions. Primary cutaneous disease remains a rare manifestation and unlike pulmonary or disseminated nocardiosis, it usually affects immunocompetent individuals. We present a case of a primary cutaneous nocardiosis of the head and neck after an insect bite in a healthy 50-year-old woman who had recently travelled from Greece. She presented with a painful right-sided swelling of her face and neck and an ulcerated plaque over the right temple. Biopsy of the plaque revealed inflammation with abscess formation indicating underlying infection. Culture from the biopsy showed growth of Nocardia spp and 16S rRNA gene sequence analysis identified Nocardia brasiliensis. The patient was treated with trimethoprim/sulfamethoxazole and subsequently switched to amoxicillin/clavulanic acid due to a drug eruption. Antibiotic therapy was continued for a total of 3 months with complete resolution of the skin lesions.

Background: Carcinoma pancreas is being diagnosed increasingly with the help of conventional imaging like ultrasonography (USG), computerized tomography (CT) scan and magnetic resonance imaging (MRI).Imaging also gives the opportunity to assess resectability. In our country MRI and CT scan are not widely available and most of the pancreatic carcinoma is too advanced for curative surgical resection when diagnosed. These are unresectable carcinoma pancreas (UCP). Objectives: To evaluate the efficacy of imaging in diagnosing carcinoma pancreas and to assess resectability after comparing them with peroperative findings. Methods: This retrospective study was carried out in the department of Hepato-Biliary-Pancreatic Surgery in Bangladesh Institute for Research and Rehabilitation in Diabetic Endocrine and Metabolic disorders (BIRDEM) hospital, Dhaka, Bangladesh from July 2004 to June 2006 (2 years). After laparotomy findings and histopathological confirmation 50 patients were labeled as UCP. Among 50 patients male were 28 & female patients were 22. Imaging modalities used before surgery was assessed and compared with per operative findings. USG were done in all patients and CTscan in 45 patients. MRI was done in 08 patients suspected clinically as pancreatic carcinoma where USG /CT scan had failed to reach a conclusion. Findings of the various imaging studies regarding diagnosis and unresectability were compared with per operative findings. Results: USG was able to diagnose 42 (84%) pancreatic carcinoma patients with unresectibility in 29 (69%). Forty five patients (90%) were diagnosed by CT scan and could label 38 (84.44%) as unresectable. MRI was 100% accurate to diagnose and label the entire 08 patient as unresectable carcinoma pancreas. Cumulative multimodal preoperative imaging was 91.33% accurate in diagnosing carcinoma pancreas and could tell the features of unresectibility in 73.59% patients. Conclusion: CT scan should be the primary imaging modality for diagnosing pancreatic carcinoma and its resectability. MRI is very promising for diagnosing and assessing UCP. Multimodal imaging is better than single imaging. Chattagram Maa-O-Shishu Hospital Medical College Journal Volume 12, Issue 3, September 2013: 23-26

Gastrointestinal bleeding in HIV patients secondary to coinfection by HHV8 and development of Kaposi’s sarcoma (KS) is a rare complication even if no skin lesions are detected on physical examination. This article indicates which patients might develop this type of clinical sign and also tries to recall that absence of skin lesions never rules out the presence of KS, especially if gastrointestinal involvement is documented. Gastrointestinal bleeding in terms of hematemesis has rarely been reported in the literature. We review some important clinical findings, diagnosis, and treatment approach. We present the case of an HIV patient who presented to the emergency department with hematemesis and gastrointestinal signs of KS on upper gastrointestinal endoscopy without any dermatological involvement.

Introduction: Myositis is an autoimmune disease characterised by proximal muscle weakness. Aim: The aim of the authors was to determine the frequency of dermatomyositis-specific autoantibodies (anti-Mi-2, anti-transcriptional intermediary factor 1 gamma, anti-nuclear matrix protein 2, anti-small ubiquitin-like modifier activating enzyme, anti-melanoma differentiation-associated gene) in a Hungarian myositis population and to compare the clinical features with the characteristics of patients without myositis-specific antibodies. Method: Antibodies were detected using immunoblot and immunoprecipitation. Results: Of the 330 patients with nyositis, 48 patients showed dermatomyositis-specific antibody positivity. The frequency of antibodies in these patients was lower than those published in literature Retrospective analysis of clinical findings and medical history revealed that patients with dermatomyositis-specific autoantibody had more severe muscle weakness and severe skin lesions at the beginning of the disease. Conclusions: Antibodies seem to be useful markers for distinct clinical subsets, for predicting the prognosis of myositis and the effectiveness of the therapy. Orv.

Abstract The limitations of 2D microscopy constrain our ability to observe and understand tissue-wide networks that are, by nature, 3-dimensional. Optical projection tomography enables the acquisition of large volumes (ranging from micrometres to centimetres) in various tissues, with label-free capacities for the observation of auto-fluorescent signals as well fluorescent-labelled targets of interest in multiple channels. We present a multi-modal workflow for the characterization of both structural and quantitative parameters of the mouse small intestine. As proof of principle, we evidence its applicability for imaging the mouse intestinal immune compartment and surrounding mucosal structures. We quantify the volumetric size and spatial distribution of Isolated Lymphoid Follicles (ILFs) and quantify density of villi throughout centimetre long segments of intestine. Furthermore, we exhibit the age- and microbiota-dependence for ILF development, and leverage a technique that we call reverse-OPT for identifying and homing in on regions of interest. Several quantification capabilities are displayed, including villous density in the autofluorescent channel and the size and spatial distribution of the signal of interest at millimetre-scale volumes. The concatenation of 3D image acquisition with the reverse-OPT sample preparation and a 2D high-resolution imaging modality adds value to interpretations made in 3D. This cross-modality referencing technique is found to provide accurate localisation of ROIs and to add value to interpretations made in 3D. Importantly, OPT may be used to identify sparsely-distributed regions of interest in large volumes whilst retaining compatibility with high-resolution microscopy modalities, including confocal microscopy. We believe this pipeline to be approachable for a wide-range of specialties, and to provide a new method for characterisation of the mouse intestinal immune compartment.

Background: Air pollution leads to several health effects, the major systems affected were respiratory, dermatology, neurology and ophthalmology. This study is an attempt to find out various health effects of pollution, from a food factory to the nearby residents.Methods: A cross sectional comparative study was performed on 248 residents nearby a food factory, situated in rural area of Thrissur district and a comparative group of 266 participants taken 5km away from this factory.Results: Both the groups were comparable in socio-demographic profile except religion and occupation. There was no statistically significant difference (p>0.05) between the use of firewood in both the groups. The symptoms of major systems involved were respiratory (odds ratio 3.9, 95% CI 2.2 to 6.8), dermatological (odds ratio 18.3, 95% CI 8.3 to 40.7), neurological (odds ratio 13.5, 95% CI 4.1 to 44.7) and ophthalmological (odds ratio 5.9, 95% CI 2.6 to 13.6). The major symptoms complained by them were pruritus (32.7%), skin lesions (17.7%), breathlessness (16.9%), itching eye (13.3%) watering from eye (11.7%) and headache (11.3%). All these symptoms among the case group compared to control group were very high and these associations were highly statistically significant (p<0.001).Conclusions: This study showed an increased occurrence of adverse health effects among the individuals who were residing near the food factory. Therefore this study points out the possibility of environmental pollution (mainly air pollution) as a main factor for the increased prevalence of symptoms among those who reside nearby the factory.
