Coexistence of pulmonary thromboembolism and pulmonary tuberculosis: a diagnostic dilemma.

A man in his early 50s with previously treated pulmonary tuberculosis (TB) presented with a 3-month history of cough, expectoration and progressive breathlessness, accompanied by significant weight loss. Examination revealed tachycardia, tachypnoea, hypoxaemia and unilateral diminished breath sounds. Investigations showed anaemia, leucocytosis and a homogeneous opacity on the left side of the CXR. ECG and echocardiography suggested pulmonary thromboembolism (PTE). A CT pulmonary angiogram confirmed a chronic embolus and a severely fibrosed left lung. A comprehensive thrombophilia workup yielded normal results and the PTE was attributed to his history of TB. Sputum analysis confirmed reactivated TB, leading to the initiation of antitubercular therapy. The patient improved clinically with plans for a repeat CT pulmonary angiography to assess the need for pulmonary thromboendarterectomy after completing TB treatment. This case highlights the possible association of TB and PTE, its management and why it should be considered as a differential diagnosis in patients with a history of TB presenting with exacerbated breathlessness.

Adenocarcinoma of the Lung Masquerading As Invasive Pulmonary Aspergillosis in an Elderly Lady: A Diagnostic Challenge.

A 59-year-old hypertensive woman presented with a year-long history of cough, expectoration, and progressive breathlessness, recently complicated by hemoptysis and significant weight loss. Initial investigations, including a chest x-ray and contrast-enhanced computed tomography (CECT) of the thorax, suggested an infective pathology. Despite negative bacterial, fungal, and tuberculosis cultures, elevated bronchoalveolar lavage (BAL) galactomannan and serum Aspergillus-specific IgG levels led to a diagnosis of invasive pulmonary aspergillosis (IPA), and antifungal treatment commenced. The patient's initial response was positive; however, symptoms recurred three months later. Further investigations revealed adenocarcinoma, confirmed by cytology from a thoracentesis. The patient, a non-smoker, began targeted therapy with tyrosine kinase inhibitors but declined further diagnostic evaluation. Despite the poor prognosis and palliative care options, the patient opted for discharge to home care. This case underscores the complexity of diagnosing lung pathologies and the importance of considering alternative diagnoses in persistent respiratory symptoms.

Hamman's syndrome - with audio file recording Hamman's sign.

A boy in his late adolescence, with no history of airway disease or medication use, presented with acute history of non-exertional chest pain increased on coughing and deep inspiration accompanied by dysphonia and odynophagia in the last 1 day. He had a notable history of viral fever with non-productive cough 2 weeks prior, which resolved spontaneously. Examination revealed stable haemodynamic parameters. Palpable non-tender crepitus was felt in left anterior chest wall, axilla and both sides of the neck. Auscultation revealed Hamman's sign. ECG showed high voltage complexes and 2-dimensional echocardiogram (2D ECHO) showed normal biventricular function. CXR was evident of subcutaneous emphysema, pneumopericardium and Naclerio's sign clinching the diagnosis of pneumomediastinum. CT findings were consistent with a diagnosis of Hamman's syndrome. Patient was admitted for observation and treated with high-flow oxygen. He improved symptomatically and was discharged on the fourth day of admission.

Hidden Behind a Veil: A Rare Case of Pulmonary Nocardiosis.

A 48-year-old male, a known case of seizure disorder, presented with complaints of cough for four months, which increased for two weeks, fever for two weeks and weight loss. Computed tomography (CT) scan of the thorax showed multiple heterogeneously enhancing lesions of bilateral lung fields predominantly in peribronchovascular distribution with enlarged, necrosed and conglomerated lymph nodes suggestive of infective etiology. On routine blood investigations, he was found to be reactive for the human immunodeficiency virus. He underwent bronchoscopy and bronchoalveolar lavage culture grew Nocardia. He was prescribed antibiotics based on susceptibility reports and the patient became symptomatically better after one month and was discharged.

Coccidioidomycosis where you least expect it.

An elderly man without history of travel presented with complaints of intermittent fever for 2 months, cough with scanty expectoration for 15 days and history of weight loss of 5 kg in 1 year. The chest X-ray and CT scan of the thorax showed dispersed centrilobular nodules and patchy subpleural consolidation in both lungs with mediastinal lymphadenopathy. He underwent bronchoscopy and bronchoalveolar lavage culture grew Pseudomonas aeruginosa He was prescribed antibiotics based on culture sensitivity; however, patient continued to have symptoms. All relevant blood investigations were within normal limits. He underwent CT-guided biopsy of the right lung lesion during which clearing of the radio-opacities present in the initial CT scan and appearance of fresh lesions in different locations were observed. Migratory shadows were suspected. Fine-needle aspiration cytology showed features suggestive of coccidioidomycosis for which antifungals were started. After 1 month, he improved symptomatically and chest X-ray showed clearance of shadows.

Outcomes of Laparoscopic vs. Open Reversal of Hartmann's Procedure: A Single Centre Experience.

Introduction Hartmann's procedure is widely performed to fix colonic obstruction and perforation. It should ideally be followed by a reversal to restore bowel continuity. Reversal of Hartmann's procedure was traditionally performed using an open technique. However, in recent days, the use of a laparoscopic approach has become increasingly popular. In our retrospective observational study, we aim to investigate the outcomes of laparoscopic versus open reversal of Hartmann's procedure in a UK tertiary centre. Methods All patients who underwent reversal of their Hartmann's procedure between January 2017 and December 2019 were included in the study. Data including demographics, days between primary operation and reversal, laparoscopic or open reversal, length of hospital stay following reversal procedure, 30-day readmission, mortality, and complication rate were collected. Statistical analysis was performed using t-test and chi-squared test. Results Forty-nine patients underwent reversal of Hartmann's procedure from January 2017 to December 2019. The mean age of our cohort was 59.6 ± 13.2 years. There was no significant difference in baseline demographics of both groups, apart from the number of days between the primary operation and reversal procedure. There was also no statistical difference in length of stay, 30-day readmission, and mortality between laparoscopic and open reversal techniques. However, there was a higher incidence of wound complications in patients who underwent open reversal of Hartmann's procedure. Conclusion The reversal of Hartmann's procedure is a challenging operation. We found no significant difference between both open and laparoscopic approaches, but our study might be confounded by various factors including small sample size and selection bias. A larger, randomised study with greater statistical power is needed to confirm our findings.

Oncological adequacy of laparoscopic rectal cancer resection: An audit in Indian perspective.

BACKGROUND: Laparoscopic resection for rectal cancer (LRR) has gained popularity because of better short-term outcomes and less post-operative morbidity. However, LRR is still not endorsed as a standard of care mainly due to concerns centred on oncological safety in comparison with open approach. Moreover, two recent randomised trials (Australian Laparoscopic Cancer of the Rectum [ALaCaRT] and the American College of Surgeons Oncology Group [ACOSOG] Z6051) have failed to prove that LRR is non-inferior to open resection. Studies on oncological adequacy of LRR in the Indian population in terms of quality of mesorectal excision are scarce. In this article, we aim to audit the oncological adequacy of LRR in our centre and thereby critically analyse the reliability of extrapolation of results of ALaCaRT and ACOSOG trials to the Indian population. METHODS: We retrospectively analysed the oncological adequacy of LRR in terms of completeness of total mesorectal excision (TME), distal and circumferential resection margin (CRM) status and nodal harvest in patients with rectal cancer who underwent LRR between January 2016 and June 2018 at our centre. RESULTS: Of 157 patients included in this study, a complete TME was achieved in 148 (94.26%) patients and nearly complete in 7 (4.46%) patients. A safe CRM (≥1 mm) was obtained in 151 (96.18%) patients. Distal margin results were negative in 155 (98.73%) patients. Average nodal harvest was 19.86 ± 9.28. Overall surgical success, calculated as a composite measure of negative distal margin and negative CRM and complete TME was 95.54%. CONCLUSION: Good quality rectal cancer resection can be achieved by experienced laparoscopic surgeons without compromising oncological safety.

Investigations for recognizing urinary stone.

This study was done to identify the value of the commonly performed investigations available for identifying urinary stone disease, namely X-ray of the kidney, ureter and bladder (KUB) regions and ultrasound scan (USS) to recognize stones in patients suspected to have the disease. Two hundred patients who attended the stone clinic with symptoms suggestive of urinary stone disease and had either stone retrieved or have been followed up for minimum of 6 months were interviewed. The final opinion on stone disease was made after follow-up to assess the efficacy of the initial opinion based on the plain X-ray KUB or USS. The patients were classified as proved stone patients only after retrieval of stones. The efficacy of the initial screening investigation was assessed to calculate the specificity and sensitivity of the two modalities of investigation. Of the 200 patients studied, all had plain X-ray KUB. Only 166 patients had USS for recognizing stones in the urinary tract; 74 patients showed positive evidence of stones either by X-ray or USS. The findings of the two modalities of investigation are given below. Number of X-rays done, 200; number positive, 24; proved positive, 24 (stone retrieved); proved negative, 0; number negative, 176; proved positive, 32 (stone retrieved); proved negative, 144; number of USS done, 166; number positive, 120; proved positive, 50 (stone retrieved); proved negative, 70; number negative, 46; proved positive, 14 (stone retrieved); proved negative, 32. USS showed back presence effects in 62 patients. Of these, 12% showed stones in the ureter, whereas the rest did not show evidence of stones. Those selected as positive stones finally had either passed stones or had PCNL, URS, cystolithotripsy or open surgery or were put on high-dose chemotherapy. Forty-six patients who had no ROS in KUB and no stones in USS passed stones subsequently. It is concluded that the plain both X-ray KUB and USS should be performed in patients with suspected stone disease for identifying stone disease and also to exclude other pathology which may produce similar urinary symptoms.

Retrieval methods for urinary stones.

This paper attempts to assess the current status of the various modalities of available treatment for urinary stone disease in the Kerala scenario. A total of 300 patients who attended the stone clinic with urinary stone disease and had stones retrieved by different means were selected for the study. Their clinical symptoms, demographic profile, size, number and position of stones, metabolic profiles, retrieval modalities and end result of treatment in terms of stone clearance were assessed. Instances of failure, incomplete clearance and complication events were noted. Based on the experiences, a flowchart was created for appropriate decision-making in urinary stone management. The modalities of retrieval included nephrectomy, nephrolithotomy, pyelo-nephrolithotomy, extended pyelolithotomy, pyelolithotomy, ureterolithotomy, cystolithotomy, urethrolithotomy, ESWL, PCNL, URS, cystolithotripsy, urethrolithotripsy and spontaneous passage. The clearance rate of stone was maximum in open surgery. The extent of stone clearance by ESWL depended on various factors. PCNL was mostly limited by the difficulties in achieving puncture at the stone site. Availability of a variety of flexible nephroscopes also altered the success rate of the procedure. There were good success rates in pushing stones from the ureter to the pelvis followed by PCNL. In patients who had successful PCNL, postoperative morbidity was significantly reduced in terms of the number of days of hospitalization, time taken for return to work, absence of urinary leak, site infection, urinoma formation and urinary tract infection. URS was performed in many patients and stones retrieved. However, the indication for the procedure remains doubtful as the size of most of the stones thus retrieved was less than 6 mm. These would have passed out spontaneously or with chemotherapeutic support. URS, lithotripsy and basketting were confronted by upward migration of stones to the kidney, requiring further procedures for retrieval. Introduction of double J stents helped in relieving urinary obstruction, particularly in patients presenting with anuria, but retained stents, forgotten stents and failed stone retrieval were common following the procedure. The procedure of URS was simplified by the presence of dilated ureter in spontaneous stone passers or those with distal obstruction and proximal dilatation. It is concluded from the study that open surgery still remains the sheet anchor of treatment of urinary stones in many patients in Kerala. Newer lesser invasive procedures should be ethically selected. Decisions should be patient based, taking into consideration the economic feasibility for the procedure proposed.
