Use of Computed Tomography of the Head in Patients With Acute Atraumatic Altered Mental Status: A Systematic Review and Meta-analysis

IMPORTANCE

The usefulness of computed tomography of the head (CTH) in patients with acute-onset atraumatic altered mental status (AMS) is poorly understood, but use in these patients remains high.

OBJECTIVE

To evaluate the use of CTH (event rate) in patients with AMS and the positive outcome event rate of the performed CTH studies.

DATA SOURCES

The PubMed/MEDLINE, PubMed Central, Embase, and CINAHL databases were searched using predefined Boolean parameters. All studies that met inclusion criteria until January 31, 2022, were included.

STUDY SELECTION

Randomized clinical trials and observational, cohort, and case-control studies were included. Conference abstracts, reviews, letters, case reports, case series, systematic literature, and meta-analyses were excluded.

DATA EXTRACTION AND SYNTHESIS

The systematic literature review was performed per Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Data were independently extracted by 2 authors. Data were pooled using a random-effects method.

MAIN OUTCOMES AND MEASURES

Event rate of CTH use in patients with acute atraumatic AMS. The CTH event rates and positive CTH event rates were calculated with 95% CIs.

RESULTS

Of 9338 studies identified, 26 qualified for the systematic review and 25 for the meta-analysis. The 25 studies in the meta-analysis included a total of 79 201 patients. The CTH event rate was 94% (proportion, 0.94; 95% CI, 0.76-1.00), and the positive CTH event rate was 11% (proportion, 0.11; 95% CI, 0.07-0.15). There was significant heterogeneity among the studies included (I2 > 50%, P < .001), for which a random-effects model was used. There was significant publication bias, as evident by an asymmetric funnel plot. There was no fluctuation of the results during the sensitivity analysis, which reassured the reliability of the data.

CONCLUSIONS AND RELEVANCE

In this meta-analysis, CTH use among patients with acute-onset atraumatic AMS was very high with a low yield. Large-scale studies are needed to guide clinical decision-making in such a situation.

Workplace violence against nurses: a narrative review

BACKGROUND AND AIM

Any harmful act Physical, sexual, or psychological committed against the nurses in the workplace by a patient or visitor is called workplace violence (WPV) against nurses. WPV is directly related to decreasing job satisfaction, burnout, humiliation, guilt, emotional stress, intention to quit a job, and increased staff turnover. The purpose of this narrative review is to explore the concept of WPV, its prevalence, consequences, influence on nursing, and strategies developed to prevent such incidences. WPV is not acceptable and, regardless of the culprit's physical or psychological status, should be held responsible for such a heinous crime. WPV can have a vastly negative impact on nurses. Unfortunately, violence in the workplace has become so common that it is now considered an unpleasant part of the job and ignored instead of being reported. Nurses should be educated appropriately on hospital policies against WPV and be encouraged to report any incidence.

RELEVANCE FOR PATIENTS

WPV is detrimental to nurse and patient's relationship which negatively affects patient care.

A Retrospective Cross-Sectional Study of Severe Breakthrough SARS-CoV-2 Infection in the General Population Requiring Hospitalization Within a Single Health System

BACKGROUND

Despite coronavirus disease 2019 (COVID-19) vaccination efforts, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in vaccinated individuals ("breakthrough SARS-CoV-2 infections") have emerged. Our understanding of breakthrough SARS-CoV-2 infections continues to evolve, and there is a paucity of information describing severe breakthrough SARS-CoV-2 infections. We conducted this study with the aim of describing breakthrough SARS-CoV-2 infections requiring hospitalization and exploring factors associated with severe breakthrough infection.

METHODS

The study included patients within our health network who received at least one dose of a messenger RNA (mRNA) COVID-19 vaccine and required hospitalization due to breakthrough SARS-CoV-2 infection from January 1 to August 15, 2021. We performed a descriptive analysis of vaccinated patients requiring hospitalization. Multivariable logistic regression (LR) analysis was performed to explore factors associated with severe breakthrough infection.

RESULTS

Out of 67,223 vaccinated individuals, 78 (0.12%) patients were hospitalized with breakthrough SARS-CoV-2 infection, of which 25 individuals (0.04% of those vaccinated, and 32% of all hospitalized) developed severe infection. The mean age of those with breakthrough infection was 72 years, the majority were White (60%), and dyspnea was the most common reason for hospital admission (53%), with bimodal peaks of hospitalization in January-February (40%) and July-August (34%). In LR analysis, male patients had 4.03 times the odds of developing severe SARS-CoV-2 infection than female patients (adjusted odds ratio (aOR): 4.03, 95% confidence interval (CI): 1.21 - 13.40), and an immunocompromising condition had 6.32 times the odds of developing severe COVID-19 disease (aOR: 6.32, 95% CI: 1.48 - 26.18).

CONCLUSIONS

The rate of severe breakthrough SARS-CoV-2 infection was very low, and male sex and immunocompromising conditions were associated with severe breakthrough infection. Clinicians and health systems should continue to campaign for COVID-19 vaccination aggressively.

Risk of post-intubation cardiac arrest with the use of high-dose rocuronium in COVID-19 patients with acute respiratory distress syndrome: A retrospective cohort study

BACKGROUND

Post-intubation cardiac arrest (PICA) is an uncommon complication of intubation, but numbers have risen to over 1.5 times the usual number since the coronavirus disease 2019 (COVID-19) pandemic. Due to expert recommendations, high-dose rocuronium (HDR) has become a commonly used pre-intubation neuromuscular blocking agent.

AIM

We conducted this retrospective case-control observational study with the hypothesis that high-dose rocuronium was not associated with higher incidence of PICA.

METHODS

We included 93 patients who were intubated using the rapid sequence intubation (RSI) technique with rocuronium for acute respiratory distress syndrome (ARDS) due to confirmed COVID-19 pneumonia, admitted from March 2020 to February 2021 to a tertiary care hospital in North Carolina, USA. The patients were grouped based on high (1.5 mg/kg of ideal body weight and above) versus low (<1.5 mg/kg of ideal body weight) dose rocuronium used for RSI. The differences of the various outcomes between the groups were analyzed.

RESULTS

The baseline demographics were similar in both groups except for higher body mass index in high-dose group 39 versus 32 (kg/m²), p = 0.009. There was a total of six PICA events (6.45%). The HDR group had 8.0% of PICA versus 4.7% in the low-dose group. In-hospital mortality was 60.0% in the HDR group versus 72.1% in the low-dose group.

CONCLUSION

The incidence of PICA in COVID-19 patients with ARDS who were intubated using the RSI technique was higher than in the pre-COVID-19 era.

RELEVANCE FOR PATIENTS

The use of high-dose paralytics during invasive ventilation with RSI and their consequences should be explored with the help of large-scale studies. The rate of PICA is still very low, and perhaps, the use of HDR is safe, as suggested by the expert panel.

Fluid resuscitation and outcomes in heart failure patients with severe sepsis or septic shock: A retrospective case-control study

Background

The use of ≥30 mL/Kg fluid bolus in congestive heart failure (CHF) patients presenting with severe sepsis or septic shock remained controversial due to the paucity of data.

Methods

The retrospective case-control study included 671 adult patients who presented to the emergency department of a tertiary care hospital from January 01, 2017 to December 31, 2019 with severe sepsis or septic shock. Patients were categorized into the CHF group and the non-CHF group. The primary outcome was to evaluate the compliance with ≥30 mL/Kg fluid bolus within 6 hours of presentation. The comparison of baseline characteristics and secondary outcomes were done between the groups who received ≥30 mL/Kg fluid bolus. For the subgroup analysis of the CHF group, it was divided based on if they received ≥30 mL/Kg fluid bolus or not, and comparison was done for baseline characteristics and secondary outcomes. Univariate and multivariable analyses were performed to explore the differences between the groups for in-hospital mortality and mechanical ventilation.

Results

The use of ≥30 mL/Kg fluid bolus was low in both the CHF and non-CHF groups [39% vs. 66% (p<0.05)]. Mortality was higher in the CHF group [33% vs 18% (p<0.05)]. Multivariable analysis revealed that the use of ≥30 mL/Kg fluid bolus decreased the chances of mortality by 12% [OR 0.88, 95% CI 0.82–0.95 (p<0.05)]. The use of ≥30 mL/Kg fluid bolus did not increase the odds of mechanical ventilation [OR 0.99, 95% CI 0.93–1.05 (p = 0.78)]. In subgroup analysis, the use of ≥30 mL/Kg fluid bolus decreased the chances of mortality by 5% [OR 0.95, 95% CI 0.90–0.99, (p<0.05)] and did not increase the odds of mechanical ventilation. The presence of the low ejection fraction did not influence the chance of getting fluid bolus.

Conclusion

The use of ≥30 mL/Kg fluid bolus seems to confer protection against in-hospital mortality and is not associated with increased chances of mechanical ventilation in heart failure patients presenting with severe sepsis or septic shock.

Low Serum Albumin Predicts Severe Outcomes in COVID-19 Infection: A Single-Center Retrospective Case-Control Study

Background

Coronavirus disease 2019 (COVID-19) can cause serious complications such as multiorgan failure and death which are difficult to predict. We conducted this retrospective case-control observational study with the hypothesis that low serum albumin at presentation can predict serious outcomes in COVID-19 infection.

Methods

We included severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) confirmed, hospitalized patients from March to July 2020 in a tertiary care hospital in the USA. Patients were followed for 21 days for the development of the primary endpoint defined as the composite outcome which included acute encephalopathy, acute kidney injury, the requirement of new renal replacement therapy, acute hypercoagulability, acute circulatory failure, new-onset heart failure, acute cardiac injury, acute arrhythmia, acute respiratory distress syndrome (ARDS), high flow oxygen support, intensive care unit (ICU) stay, mechanical ventilation or death; and the secondary endpoint of death only. Univariate and multivariate logistic regression analyses were performed to study the effect of albumin level and outcomes.

Results

The mean age was 56.76 years vs. 55.67 years (P = 0.68) in the normal albumin vs. the low albumin group. We noticed an inverse relationship between serum albumin at presentation and serious outcomes. The low albumin group had a higher composite outcome (93.88% vs. 6.12%, P < 0.05) and higher mortality (13.87% vs. 2.38%, P < 0.05) in comparison to the normal albumin group. The multivariate logistic regression analysis revealed higher odds of having composite outcomes with lower albumin group (odds ratio (OR) 10.88, 95% confidence interval (CI) 4.74 - 24.97, P < 0.05). In the subgroup analysis, the multivariate logistic regression analysis revealed higher odds of having composite outcomes with the very low albumin group (OR 7.94, 95% CI 1.70 - 37.14, P < 0.05).

Conclusions

Low serum albumin on presentation in COVID-19 infection is associated with serious outcomes not limited to mortality. The therapeutic option of albumin infusion should be investigated.

Low serum albumin and the risk of hospitalization in COVID-19 infection: A retrospective case-control study

BACKGROUND

The data on the COVID-19 patients who were discharged to self-quarantine is lacking.

AIM

The aim of the study was to investigate the percentage of COVID-19 positive patients that were hospitalized within a three-week period after discharge from ED to self-quarantine.

METHODS

The patients who had confirmed SARS-CoV-2 on RT-PCR of the nasopharyngeal swab and were discharged from ED of a tertiary care hospital in the USA to self-quarantine from March 01- July 31, 2020, were included. Patients were divided into two groups based on serum albumin levels and were followed up for three weeks to see if low level of albumin increased the risk of hospitalization. Univariate and multivariate logistic regression analyses were performed to study the effect of albumin level and outcomes.

RESULTS

A total of 112 patients were included in the study out of which 65 had low serum albumin (<3.5 g/dL) and 47 had normal serum albumin (≥3.5 g/dL). More than 10% of patients discharged to self-quarantine needed hospitalization within three weeks. The Low albumin group had more co-morbidities at baseline. The low serum albumin group had 10 (15.38%) vs 2 (4.26%), p = 0.06 hospitalizations as compared to the normal serum albumin group. The multivariate logistic regression analysis did not reveal lower odds of hospitalization in the group with normal albumin, (OR 0.26, 95% CI 0.03-1.92, p = 0.19) after controlling for age, sex, and various co-morbidities.

CONCLUSION

The low serum albumin was not associated with the risk of hospitalization in COVID-19 patients who were initially discharged to self-quarantine.

Delayed onset serotonin syndrome in the setting of polypharmacy

Serotonin syndrome is a rare but well-known condition that can be life-threatening if not diagnosed early. Onset is usually within 4 to 13 h of starting the offending medication. We present a case of delayed onset of serotonin syndrome that presented after 48 h. Polypharmacy played a role in causing the onset of symptoms. Clinicians should keep a high index of suspicion for serotonin syndrome when dealing with elderly confused patients who take multiple medications even when the onset is delayed or atypical because the outcome can be disastrous.

An unusual case of severe hypercalcemia: as dehydrated as a bone

Objective: Severe hypercalcemia is a medical emergency. Hyperparathyroidism, malignancy, vitamin D toxicity, infections such as tuberculosis, or systemic illness such as sarcoidosis are all possible etiologies. Among the less studied causes is dehydration. Our objective is to identify dehydration as an etiology of hypercalcemia.

Methods: Extensive literature review did not recognize dehydration as an etiology of hypercalcemia. We present a case of dehydration leading to severe hypercalcemia in a 60-years-old female with a presentation of altered mental status and corrected calcium level of 19 mg/dL in the absence of parathyroid abnormality, vitamin D toxicity, systemic disease, or malignancy.

Results: Dehydration caused hypercalcemia which led to a feed-forward mechanism and caused further worsening dehydration, worsening kidney function, and severe hypercalcemia. The patient responded very well to intravenous fluid and at the time of discharge had a serum calcium of 9.8 mg/dL with improved mental status back to the baseline.

Conclusion: Our literature review demonstrated many causes of hypercalcemia, with dehydration being exceptionally rare. It is our hope that this case report may serve as evidence of one such instance, allowing providers to keep a working differential of dehydration in severely elevated calcium levels.

Diabetes mellitus as a risk factor for cryptococcal meningitis in immunocompetent

Cryptococcal meningoencephalitis (CM) is one of the major causes of mortality and morbidity in immunocompromised patients estimating 650,000 deaths each year. Across the globe, CM has been occasionally seen in apparently immunocompetent patients who otherwise don’t have established risk factors. The clinical presentation of CM in immunocompetent hosts is subtle and often results in complications including persistent neurological deficits and death. We present a case of Cryptococcal neoformans meningitis in a diabetic female with no other identified risk factors. Although her clinical presentation was atypical, her clinical course was uncomplicated. The pathophysiology in immunocompetent hosts appears somewhat different, so is the clinical presentation. Since there are no separate evidence-based treatment recommendations, it is challenging to treat this group of patients. There seems to be a need for further studies for management in CM for HIV negative, non-transplant immunocompetent patients.

Obstructive Sleep Apnea: Risk Factor for Arrhythmias, Conduction Disorders, and Cardiac Arrest

Background Obstructive sleep apnea (OSA) has been described as a risk factor for cardiac arrhythmias. Its association with atrial fibrillation has been established. However, relationships with other arrhythmias and conduction disorders have not been fully studied. Methods We used the National Inpatient Sample database from 2009 to 2011 to explore the relationship between OSA and arrhythmias and conduction disorders. The presence of diagnosis was determined based on the International Classification of Disease-9 (ICD-9) codes. Univariate and multivariate logistic regressions were used to establish mortality risks among all groups. Results Multivariate logistic regression showed increased mortality in patients with OSA in comparison to patients without OSA and patients across all categories of arrhythmias and conduction disorders. One significant finding was the increased association of cardiac arrest in patients with OSA versus patients without OSA (OR: 95.72; CI: 89.13-105.81, p < 0.001). Conclusions OSA is significantly associated with non-atrial fibrillation arrhythmias, conduction disorders, and sudden cardiac arrest. Awareness regarding this association is important for early screening for OSA in obese patients to prevent cardiovascular morbidity and mortality. The use of continuous positive airway pressure (CPAP) might be beneficial against all kinds of arrhythmias and sudden cardiac death.

Fine needle aspiration cytology of head and neck lesions and its correlation with histopathology

Background: Fine needle aspiration cytology is a minimally invasive technique used in the initial diagnosis of different types of lesions located in head and neck region commonly originating from cervical lymph node, thyroid gland, salivary glands and soft tissues. The objective of this study was to evaluate the diagnostic accuracy, sensitivity and speci city of FNAC in various head and neck lesions in correlation with their histopathological examination. Materials and methods: A hospital based prospective study was conducted among 209 patients with palpable head and neck region swellings in the Department of Pathology, Bhaktapur Cancer Hospital and the Department of Pathology, Nepal Medical College from August 2014 to July 2015. FNAC were done from palpable masses of head and neck regions. Data entry and analysis were done using SPSS 17. Result: There were 209 FNAC cases enrolled, out of which lymph node lesions (n=128) were the most common lesions followed by thyroid (n=40), other soft tissues (n=27) and salivary gland (n=14). Reactive lymph nodes, colloid goiter, epidermoid cyst and sialadenosis were the predominant diagnosis of lymph nodes, thyroid gland, soft tissues and salivary gland respectively. Highest accuracy, sensitivity and speci city were observed in thyroid gland, salivary gland and soft tissues. However, four false negative results for malignancy were reported in lymph node lesions. Conclusion: Head and neck region swellings are the commonly encountered conditions. FNAC being highly accurate, sensitive and speci c makes it useful and reliable procedure for screening and diagnosis of palpable masses in head and neck region. 

Etiological study of microcytic hypochromic anemia

Background: Microcytic hypochromic anemia is a distinct morphologic subtype of anemia with well- de ned etiology and treatment. The objective of this study was to determine the etiology and frequency of microcytic hypochromic anemia. Materials and Methods: This cross-sectional observational study was conducted at Kathmandu Medical College Teaching Hospital. One hundred cases of microcytic hypochromic anemia were included. Relevant clinical history, hemogram, reticulocyte count, iron pro les were documented in a proforma. Bone marrow aspiration and hemoglobin electrophoresis was conducted when required. Data was analysed by Microsoft SPSS 16 windows. Result: Iron de ciency was the commonest etiology (49%). Dysfunctional uterine bleeding (20.8%) was the commonest cause of iron de ciency, malignancy (24.3%) was the commonest cause of anemia of chronic disease. Mean value of Mean Corpuscular Volume was lowest in hemolytic anemia (71.0 ). Mean Red cell Distribution Width was normal (14.0%) in hemolytic anemia but was raised in other types. Mean serum iron was reduced in iron de ciency anemia (32.2μg/dl) and chronic disease (34.8μg/dl), normal in hemolytic anemia (83μg/dl) and raised in sideroblastic anemia (295μg/dl). Mean serum ferritin was reduced in iron de ciency anemia (7.6ng/ml), raised in chronic disease (158.6ng/ml) and normal in hemolytic anemia (99.2ng/ml). Serum ferritin was normal in sideroblastic anemia (93ng/ml). Mean Total Iron Binding Capacity was raised in iron de ciency anemia (458μg/dl) and normal in other microcytic hypochromic anemias. Conclusion: Diagnosis of microcytic hypochromic anemia requires a standardized approach which includes clinical details, hemogram, peripheral blood smear, reticulocyte count, iron pro le, hemoglobin electrophoresis and bone marrow examination. 

Recurrence Risk of Febrile Seizures in Children

BACKGROUND

Identifying children with febrile seizure who are at risk for recurrence is important so that special attention can be given to them. The objective of this study was to identify the risk factors for recurrence of febrile seizures in children.

METHODS

This prospective hospital based study was conducted from July 2013 to August 2014 'among children of 6 months to 6 years of age at Bishweshwar Prasad Koirala Institute of Health Sciences (BPKIHS), Nepal. Children meeting the selection criteria were enrolled in study. Clinical, investigation, treatment and outcome parameters were analyzed.

RESULTS

A total of 92 children with febrile seizure were enrolled in study. Males accounted for 70% and females 30%. Simple febrile seizure was present in 48% and complex febrile seizures were seen in 52%. Recurrence of seizure was seen in one third of cases. Loss of consciousness was most common post-ictal phenomenon followed by confusion and lethargy. Upper respiratory infection was the most common precipitating factor. Generalized Tonic Clonic Seizure was the most common seizure type present in 79% of cases. Significant risk factors for recurrence occurred in males (p=0.088), age less than 1 year (p=0.003). Most of the recurrence occurred within one year of first seizure.

CONCLUSIONS

Febrile Seizure is common in males. Almost one third of children with febrile seizure are at risk for recurrence. The significant risk factors for recurrences are male gender and age <1year.

Outcome of Twin Deliveries at a Tertiary Care Centre of Eastern Nepal

BACKGROUND

Twins, compared to singletons, have higher perinatal mortality and morbidity. The aim of this study was to describe the twinning rate, epidemiological variables and hospital outcome of twin deliveries and to find out ways of better management of twins in our part.

METHODS

A retrospective evaluation of the outcome of 92 twin pregnancies during one year study period (1st January 2014 to 31st December 2014) was conducted at BPKIHS. Twins delivered within the institution were included but cases less than 28 weeks gestation were excluded. Maternal and neonatal data were retrieved and analysed.

RESULTS

The twinning rate was 9.2/1000 (92/10,031). The mean birth weight was 1636.30 ±339.21 grams and mean gestational age 34.31±2.67 weeks(28 - 40 weeks). One hundred eighty-two babies (98.9%) were low birth weight (LBW) while 32.1% were small for gestational age (SGA). There was mild, moderate and severe growth discordance in 63 (68.5%)22 (23.9%)and 7 (7.6%) respectively. Three (3.26%) of 92 pairs had twin-to-twin transfusion syndrome. The hospital mortality rate was 10.87% (20/184) and 69 (37.5%) babies had complications. The clinical causes of death were hyaline membrane disease in 7 (3.3%), severe birth asphyxia in 5 (2.7%), congenital malformations in 3(1.6%) and sepsis in 3 (1.6%) babies.

CONCLUSIONS

Twin deliveries are common in this hospital and have poor hospital outcome with more complications and mortality. Hence there is a need for further studies with long term follow-ups to plan for better management of twins in our part.

Benign cystic lymphangioma of sigmoid mesocolon presenting as abdominal catastrophe: an extremely rare entity

Mesenteric cystic lymphangiomas (MCLs) are uncommon benign cystic tumours of  unknown aetiology, most often seen in paediatric patients. The clinical presentation  ranges from an incidentally discovered abdominal cyst to symptoms of acute  abdomen. A10-year-old male presented with generalized abdominal pain, nausea  and vomiting & constipation of several hours duration. Emergency laparotomy  revealed multiple cystic masses along both the sides of sigmoid colon and mesocolon,  which were inflammed mimicking diverticulosis. Sigmoidectomy with colorectal  anastomosis was performed. The postoperative course was uncomplicated. MCLs  should be included in the differential diagnosis of cystic intra-abdominal lesions.  Even when asymptomatic and discovered incidentally, they must be treated surgically  because of the potential to grow, invade vital structures and develop life-threatening  complications.  Health Renaissance 2014;12(2): pp: 130-132

Cervical pap smear- A prospective study in a tertiary hospital

Background: Cervical cancer is a leading cause of mortality and morbidity among women worldwide and most common gynaecological cancer in developing countries. Papanicolaou smear is a simple and cost effective screening test for cervical cancer. The aim of this study is to evaluate and interpret the cervical pap smear cytology in a tertiary hospital. The interpretation and reporting of the pap smear is based on 2001Bethesda system.Materials and methods: This is a prospective study conducted in a tertiary hospital, Nepal Medical College over a period of two and a half years (January 2013 to June 2015). All cervical pap smears received in the department of Pathology in the study period were included.Results: A total of 4160 cervical pap smears were reported in the study period. Majority of the cases were Negative for Intraepithelial lesion or malignancy (87.9%). Bacterial vaginosis, atrophy and reactive cellular changes associated with inflammation were seen in 5.3%, 2.4% and 1.5% cases respectively.   Epithelial cell abnormalities (0.5%) include Atypical squamous cells of undetermined significance, Low grade squamous intraepithelial lesion and High grade intraepithelial lesion. 88% of Low grade squamous intraepithelial lesion was seen in reproductive age group (20-45 years).Conclusion: Cervical cancer is the most common gynaecological cancer in the developing countries. Pap smear is the simple and cost effective screening tool to detect pre invasive cervical epithelial lesions.

Accuracy of fine needle aspiration cytology in diagnosis of thyroid swelling

Background: Fine needle aspiration cytology has been shown to be simple, safe, cost effective and quick to perform procedure with excellent patient compliance. It is a well established technique for preoperative investigation of thyroid gland swellings with high sensitivity, specificity and accuracy. The aim of this study was to determine the accuracy of fine needle aspiration cytology of thyroid swellings performed at our institution. Materials and Methods: This study was carried out at Kathmandu Medical College and Teaching hospital, department of Pathology over a period of 3 years (January 2010 to December 2012). Two hundred and seventy three patients of all age groups and both sexes who underwent fine needle aspiration cytology for thyroid swelling were evaluated. Out of 273 patients, histopathological diagnosis was available in 45 patients. Results: Fine needle aspiration cytology result revealed 245 cases (89.7%) as non-neoplastic, 21 cases (7.7%) as neoplastic and 7 cases (2.6%) inadequate due to lack of cellularity. The commonest lesion in the thyroid gland was colloid goiter. Among the malignant neoplasms the commonest was papillary carcinoma. Out of 273 patients, histopathological diagnosis was available in 45 patients. Statistical analysis of our data shows the diagnostic accuracy of fine needle aspiration cytology to be 95.7%. Fine needle aspiration cytology showed a sensitivity of 96.4% and a specificity of 94.4%. Conclusion: Fine needle aspiration cytology is a well established technique for pre operative investigation of thyroid gland swellings with high sensitivity, specificity and accuracy.

Paraganglioma of the Larynx

Paraganglioma of the larynx is a rare tumor that arises from paraganglion cells. These tumors are generally considered benign and have to be differentiated from other neuroendocrine tumors. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Surgical excision generally confers complete cure of the tumor. We hereby present a case of laryngeal paraganglioma in a 60-yearold female, who underwent total laryngectomy following a diagnostic micro-laryngeal biopsy, which was supported by immunohistochemistry. DOI: http://dx.doi.org/10.3126/jpn.v2i3.6031 JPN 2012; 2(3): 245-247
