RESUMEN
Benign paroxysmal positional vertigo (BPPV) is characterized by brief episodes of vertigo triggered by changes in head position caused by the displacement of otoliths from the utricle to the semicircular canals, particularly the posterior canal. This study explored the potential link between BPPV, the patient's preexisting conditions, and surgery-related factors including surgical positioning, duration of the procedure, exposure to vibratory forces, and anesthesia effects. This report presents two cases of BPPV following major joint replacement surgery. The first case involved a 65-year-old male with a history of diet-controlled diabetes who had undergone right-sided total hip replacement. The second case was that of a 60-year-old female with a history of osteoporosis managed with bisphosphonate therapy and left-sided knee replacement. Both patients developed vertigo symptoms one day postoperatively and were diagnosed with BPPV. In both cases, the Dix-Hallpike test confirmed the right-sided posterior canal BPPV diagnosis, and the patients were successfully treated using the Epley maneuver. Notably, there was no recurrence of vertigo at the four-week follow-up. These cases highlight the importance of considering BPPV in patients presenting with vertigo symptoms after joint replacement surgery, especially in the presence of comorbidities like diabetes and osteoporosis which possibly increase susceptibility to BPPV. This article presents two cases of benign paroxysmal positional vertigo (BPPV) following non-otologic surgery. It explores the pathophysiological mechanism underlying BPPV after such surgeries and also discusses the diagnosis and treatment approaches. This underscores the need for prompt diagnosis and treatment of BPPV to improve postoperative outcomes.
RESUMEN
The COVID-19 pandemic has led to mortality and morbidity since December 2019. Many possible treatment options have been advised till date. The role of ivermectin in the treatment of COVID-19 disease remains controversial. The aim of our study was to evaluate the effect of ivermectin in hospitalized patients with non-severe and severe COVID-19 disease. We conducted a retrospective cohort study that compared outcomes in 2 groups of COVID-19 patients hospitalized at the largest tertiary care center of Pakistan. The study group was given ivermectin along with standard treatment of covid-19 disease; the comparison group was not. Data on mortality, inflammatory markers such as C-reactive protein (CRP) and ferritin, length of hospital stay and baseline characteristics were collected from Aga Khan University's database from October 2020 till February 2021. Statistical analysis was done to determine the effectiveness of ivermectin in non-severe and severe COVID-19. Comparison of effectiveness of Ivermectin in both the genders was also conducted. The cohort included 188 patients out of which 90 were treated with ivermectin. Mortality and length of hospitalization was not found to be significantly different in the study group compared with the control group (5.6% vs 5.1%; p=0.87 and 5 days vs 4 days; p=0.27). Analysis of secondary outcomes did not yield statistically significant results, apart from ferritin levels which were significantly less in patients treated with ivermectin (547.1 vs 756.7; p=0.03). The ferritin and CRP levels in affected males were higher than in females on admission and discharge. Our findings suggest ivermectin does not significantly affect all-cause mortality, length of hospitalization and CRP levels in hospitalized COVID-19 patients. Large scale randomized controlled trials (RCTs) are required to further evaluate the role of ivermectin in covid-19 disease.

Tracheobronchopathia osteochondroplastica (TPO) is a rare disorder of the tracheopulmonary tree characterised by osseous and cartilaginous submucosal nodules projecting into the tracheal lumen, sparing the posterior tracheal membranous wall. Symptoms are non-specific and may include dry cough, hoarseness, dyspnoea, recurrent pneumonia and occasionally haemoptysis. A fibreoptic bronchoscopy showing multiple tracheal nodules followed by pathological biopsy is required to reach the final diagnosis. Here, we report two cases of TPO, both with history of biomass fuel exposure and almost similar clinical presentions with chronic cough, shortness of breath and intermittent haemoptysis. They both underwent fibreoptic bronchoscopy showing multiple tracheal nodules whose histopathological analysis showed the diagnosis of TPO. Both patients were treated conservatively and remained in good health afterwards. Physicians should be aware about the need of advanced surgical procedures including endotracheal stent placement in more severe cases.

Teratomas can be found in different organs of the body and may involve gonads, saccrococcygeal region, mediastinum and other sites. Intrathoracic teratomas always occur in mediastinum and less often arise within the lung. As teratomas mostly involve sex organs (gonads), they rarely occur as extra-gonadal tumors accounting for only 3% of all the cases and very small percentage of such tumors occur in mediastinum.We reported an interesting case of middle aged male who presented to us with symptoms of cough, hemoptysis and trichoptysis (hair expectoration).We found that patient had intrapulmonary teratoma that was initially being treated as case of pulmonary tuberculosis. He underwent surgical resection of his cavitatory lesion and diagnosis of intrapulmonary teratoma was confirmed by histopathology as well. The patient made remarkable recovery with complete disappearance of his symptoms. From Pakistan no such case has ever been reported. Although it is very unusual but in patient with cavitatory lesion, intrapulmonary teratoma should always be kept in mind as differential diagnosis.

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial lung disease (ILD) that predominantly affects older adults. IPF has the highest mortality burden of all ILDs. Data on mortality in patients with IPF is limited in developing countries. OBJECTIVES: To identify factors associated with mortality in patients with IPF at a tertiary care center in Pakistan. METHODS: A retrospective chart review was conducted at the Aga Khan University Hospital (AKUH) in Karachi, Pakistan from January 2005 to December 2015. Patients were assessed for smoking status, clinical onset of disease, pulmonary hypertension, disease severity based on spirometry and hypoxemia. RESULTS: A total of 239 cases were reviewed, of which 103 were non-survivors. A total of 45 (18%) were current smokers and 71 (29.7%) were ex-smokers. Smoking was more common in non-survivors (56.3% P ≤ .01). Pulmonary hypertension was present in 18.8% of patients. 95.4% of patients who had received pirfenidone treatment were alive at the time of study. On multivariate analysis, pirfenidone treatment (OR 0.03; 95% CI 0.01-0.08), current smoking (OR 2.60; 95% CI 1.04-6.58), age older than 60 years (OR 2.63; 95% CI 1.04-6.58) and hypoxemia (OR 3.29; 95% CI 1.58-6.84) were the factors associated with mortality. CONCLUSION: Smoking, age greater than 60 years and hypoxemia were identified as factors that increased the odds of mortality in IPF patients, whereas pirfenidone was found to lower the odds of mortality.

In cases of pulmonary embolism, the visualization of a free-floating right heart thrombus on conventional transthoracic echocardiography is extremely rare. Even rarer is an echocardiographic recording of migration of a free-floating clot from the right heart into the pulmonary vasculature leading to pulmonary embolism. We present a unique case of an elderly man who presented with dyspnoea, in whom a routine 2-D bed side transthoracic echo recorded the live transit of a free floating thrombus from the right heart into the pulmonary artery resulting in pulmonary embolism. The patient remained haemodynamically stable and was managed with anticoagulation. Our case objectively highlights the rare occurrence of free floating right heart thrombi and their association with pulmonary embolism and also focuses on the options of management of such thrombi.

OBJECTIVE: To determine the clinical features and patterns of interstitial lung disease. METHODS: This retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised record of patients diagnosed with interstitial lung disease from January 2005 to December 2015. All patients aged 16 years and above diagnosed with interstitial lung disease on the basis of clinical features, radiological features on high-resolution computed tomography of the chest, and lung biopsies were included. SPSS 19 was used for data analysis. RESULTS: Of the 537 patients, 324(60.3%) of the participants were females. The overall mean age was 60.5±14.9 years. The most common co-morbid condition was diabetes mellitus in 72(13.4%) patients, followed by hypertension in 48(8.9%) and ischaemic heart disease in 21(3.9%). The most common interstitial lung disease was idiopathic pulmonary fibrosis in 217(40.4%) patients, followed by non-specific interstitial pneumonia in 106(19.7%), sarcoidosis in 82(15.3%) and connective tissue disease-related interstitial lung disease in 56(10.4%) patients. CONCLUSIONS: Idiopathic pulmonary fibrosis was found to be the most common interstitial lung disease subtype followed by non-specific interstitial pneumonia, sarcoidosis and connective tissue disease-related-interstitial lung disease.

Endobronchial tuberculosis (EBTB) is a tuberculous infection of the tracheobronchial tree with microbial and histopathological evidence. Patients may present with symptoms secondary to disease itself or from the complication of disease like endobronchial obstruction. Diagnosis requires a high index of suspicion. Computed tomography (CT) and bronchoscopy along with microbiological investigations are the most useful diagnostic tools for the confirmation as well as for the evaluation of the tracheobronchial stenosis. The goals of treatment are eradication of tubercle bacilli with anti-tubercular medications and the prevention of airway stenosis. Interventional Bronchoscopic techniques and surgery is required for those patients who develop severe tracheobronchial stenosis that causing significant symptoms including dyspnea, repeated post obstructive pneumonia or bronchiectasis.
RESUMEN
OBJECTIVE: To identify clinical features of severe malaria and their association with adverse outcomes according to recently proposed WHO guidelines and observe treatment failure to Quinine. METHODS: This descriptive study was performed at Civil Hospital Karachi from September 2007 to January 2008. Various clinical features and laboratory parameters were analyzed according to t WHO guidelines and treatment failure to anti-malarial drugs was recorded. Mean, frequencies, percentages and chi-square test were used for analysis. Statistical significance was defined as p-value < 0.05. RESULTS: Total of 81 patients were enrolled in the study. Mean age of children was 5.5 +/- 3.4 years. Type of malaria infections that were seen included falciparum 46 (57%), mixed infection 26 (32%) and vivax 9 (11%). Frequent clinical features included splenomegaly (74%), multiple organ dysfunction (MOD) (70%), cerebral malaria (31%) and malnutrition (27%). Thrombocytopenia (86%) and severe anaemia (42%) were the common laboratory findings. Shock (p < 0.001), renal failure (p < 0.001), hepatic involvement (p < 0.002) and cerebral malaria (p < 0.002) emerged as strong predictors of complications. Fourteen out of 81 cases showed early treatment failure to Quinine. CONCLUSION: Shock, renal failure, hepatic involvement and cerebral malaria are strongly associated with complications in severe malaria. MOD and malnutrition were identified as significant new clinical features present in severe malaria in this study.
