Efficacy and Safety of Supracostal Access for Mini Percutaneous Nephrolithotomy in Pediatric Patients.

OBJECTIVE: To evaluate the efficacy and safety of supracostal percutaneous nephrolithotomy (PCNL) through the 11th intercostal space and compare it with subcostal PCNL in children with renal calculi. MATERIALS AND METHODS: Children with renal calculi who underwent PCNL between January 2010 and December 2017 were divided into 2 groups: supracostal PCNL (group 1) and subcostal PCNL (group 2). Stone location, stone burden, location of the access points, operative time, postoperative visual pain score, success rate, hospital stay, and complications according to the modified Clavien classification were compared. Comparison of medians was done using Mann Whitney U test and the means were compared using t test. RESULTS: Group 1 had 50 patients while group 2 had 60 patients. The stone-free rate was 84.0% and 85.0% in groups 1 and 2, respectively after 1 session of PCNL (P = .885). After auxiliary procedures, it increased to 96.0% and 96.6%, respectively (P = .852). The mean fall in hematocrit was 0.9% in group 1 and 1.5% in group 2 (P = .11) whereas the median pain score was 4 in group 1 and 3 in group 2 (P = .37). In all, 54 complications were recorded the commonest among which were grade I (81.5%). Twenty-nine complications were observed in group 1 while 25 complications were observed in group 2 (P = .088). One patient developed nephropleural fistula while another patient developed hydropneumothorax. Both belonged to group 1. CONCLUSION: Supracostal access for PCNL is an effective and safe alternative to subcostal access for children with renal calculi in terms of stone-free rate and complications.

Adult Bochdalek Hernia with Organo-Axial Gastric Volvulus: Misdiagnosed as Hydropneumothorax.

Bochdalek hernia (BH) in an adult may manifest clinically with a myriad of abdominal or chest symptoms or a combination of them. Diagnosis of an adult BH is usually delayed in view of rarity of the lesion and its varied presentation. A 30-year-old adult gentleman presented to us with a left thoracostomy which was draining pus and ingested food particles. The tube thoracostomy had been performed in another hospital for an apparent left hydropneumothorax before he arrived in our hospital. Computed tomography of Chest and abdomen revealed a left diaphragmatic defect with herniation of stomach, spleen and omentum into the chest with organo-axial volvulus of the stomach. A thoracostomy tube was seen to be traversing through the stomach with its tip located close to the left pulmonary artery. The patient underwent left thoraco-abdominal exploration with dissection and reposition of the hernial contents in the abdominal cavity. The gastric perforations and the diaphragmatic defect were repaired. This case reiterates a well-known fact that an adult type BH must find a place in the differential diagnosis of a hydropneumothorax. Though the adult BH is a rare diagnosis, unawareness or reluctance to consider the possibility of adult BH may prolong the suffering of the patient as it happened in our patient who had iatrogenic perforation of the stomach due to tube thoracostomy.

Pyopneumothorax secondary to Streptococcus milleri infection.

We report a case of a 46-year-old Malay woman with underlying hypothyroidism post thyroidectomy who presented with worsening breathlessness, orthopnoea, productive cough and left-sided pleuritic chest pain of 3 days duration. Chest X-ray on admission showed left-sided massive hydropneumothorax. Pleural tapping revealed empyema. A chest tube was inserted immediately. The culture of pleural fluid grew Streptococcus constellatus The patient was treated with antibiotics for a total of 6 weeks and underwent open thoracotomy and decortication during admission. Subsequently, her lung condition improved and there was no evidence of recurrence during follow-up.

A rare presentation of hydropneumothorax in tropical pulmonary eosinophilia: cavitation and pneumonic consolidation in a child.

Tropical pulmonary eosinophilia (TPE) is a syndrome of wheezing, fever and eosinophilia seen predominantly in the Indian subcontinent and other tropical areas. The pathogenesis is due to an exaggerated immune response to the filarial antigens which includes type I, type III and type IV reactions with eosinophils playing a pivotal role. Leucocytosis with an absolute increase in eosinophils in the peripheral blood is the hallmark of TPE. Other criteria for the diagnosis of TPE include high titres of antifilarial antibodies, raised serum total IgE > 1000 ku/L and a favourable response to the antifilarial agent, diethyl-carbamazine. Although TPE runs a benign course, if left untreated, it could result in a fair degree of respiratory morbidity.

A Case of Spontaneous Rupture of the Diaphragm in a Young Pregnant Female Presenting with Hydropneumothorax.

We present a case of spontaneous rupture of the diaphragm in a young pregnant female mimicking hydropneumothorax. She had a chest tube placed on admission without any improvement in her symptoms, which led to further imaging. Chest and abdomen CT after a barium swallow confirmed the clinical diagnosis. She had definitive surgical repair followed by an uneventful clinical recovery.

Chest X-ray findings in late-onset congenital diaphragmatic hernia, a rare emergency easily misdiagnosed as hydropneumothorax: a case report.

INTRODUCTION: Late-onset congenital diaphragmatic hernia is a rare anomaly with misleading symptoms and signs. CASE PRESENTATION: We describe the case of a 7-year-old Middle Eastern girl who presented with acute nonspecific abdominal symptoms and respiratory distress of 2 days' duration after sustaining a blunt trauma on her left chest wall on a background of chronic ill-defined left chest pain of 2 weeks' duration. Her initial chest radiograph showed an air-fluid level, which was thought to be a hydropneumothorax, so a chest tube was inserted and was shown to be positioned between the chest wall and the air collection; therefore, a nasogastric tube was inserted and it was positioned in the left chest cavity so the diagnosis of late-onset congenital diaphragmatic hernia was made. On retrospective analysis of the first abdominal X-ray, it showed a subtle lucent area that was triangular in shape and continued with the chest cavity, which indicates a sign of diaphragmatic hernia. In addition, the next unusual point was the nonvisualization of the diaphragm, which should be reported in any abdominal X-ray. An exploratory laparotomy was performed on our patient using a left-sided subcostal incision; the operative findings revealed a very small posterior rim of the diaphragm and a hypoplastic left lung. Her stomach, spleen, and left colon with the omentum were in the left side of her chest. She made an uneventful recovery postoperatively and was discharged after 1 week. CONCLUSIONS: Gastric and intestinal gas shadow distribution provides an important marker in the diagnosis of late-onset congenital diaphragmatic hernia and should be sought for in every case of suspected congenital diaphragmatic hernia in addition to noting the position of the nasogastric tube in the chest cavity.

Filarial hydropneumothorax: a strange journey.

Filarial infection can have varied manifestations, but hydropneumothorax at presentation has not yet been reported. A 28-year-old man presented to our hospital with heaviness of the left chest for the past 10 days, which was preceded by a sudden, short stabbing pain in the left chest after straining. Chest X-ray revealed left-sided hydropneumothorax. A peripheral blood picture revealed significant eosinophilia. A pleural fluid report also showed eosinophilia and a few motile microfilaria of Wuchereria bancrofti. Microfilaria was also documented in peripheral blood. There was no evidence of other organ system involvement. The patient was diagnosed with 'Filarial Hydropneumothorax'. After treatment with a temporary chest drain and oral diethylcarbamazine citrate, there was dramatic relief of symptoms and radiological improvement. The patient has been symptom free with no features of recurrence through 8 months of follow-up.

Diaphragmatic hernia mimicking hydropneumothorax: common error in emergency department.

Detection of diaphragmatic hernia in the acute setting is problematic and diagnosing diaphragmatic hernia as hydropneumothorax is not an uncommon mistake. We present a series of four such cases diagnosed over a 7-year period, from December 2004 to January 2011 and analyse them for how this mistake can be avoided. In case of all the patients reported by us the initial radiographs were technically compromised because the patient could not be positioned properly. Also they were examined by non-radiologists. We feel that treating surgeons in emergency department tend to overdiagnose pneumothorax as it is a life-threatening condition. We feel that in the appropriate setting suspicion of diaphragmatic hernia should be raised in patients having fractured ribs associated with homogenous opacity, which cannot be differentiated from the diaphragm. Evidence of loculation of hydropneumothorax in the appropriate setting should also raise the possibility of diaphragmatic hernia.

Simultaneous bilateral spontaneous hydropneumothorax: a rare presentation of bilateral malignant pleural mesothelioma.

This is a case of a 69-year-old man with a history of asbestos exposure who presented with acute shortness of breath. His chest x-ray showed bilateral hydropneumothorax. Further investigations including CT chest and video-assisted thoracoscopic surgery revealed bilateral pleural thickening and histology confirmed epithelioid mesothelioma. This case highlights the need for clinicians to be aware of atypical presentations of malignant pleural mesothelioma as well as the importance of considering underlying secondary causes such as malignancy in the older patient presenting with spontaneous pneumo/hydropneumothorax.

[Non-tuberculous pleural infections versus tuberculous pleural infections]. / Atteintes pleurales non tuberculeuses versus atteintes pleurales tuberculeuses.

INTRODUCTION: In countries where tuberculosis is endemic, the main differential diagnosis for pleural infection by common bacteria is pleural tuberculosis. OBJECTIVE: The purpose of our study was to determine the differences between pleural infection by common bacteria and that caused by pleural tuberculosis. METHODOLOGY: Our study was a retrospective analysis and compared the characteristics of confirmed pleural infection by common bacteria (PIB) and that due to pleural tuberculosis (PT). RESULTS: For the PIB, the signs evolved for 2.4 ± 1.4 weeks versus 5.6 ± 2.2 weeks for the PT (P=0.01). In multivariate analysis, for PIB the onset of symptoms was more abrupt (OR=3.8 [1.5; 9.9]; P=0.01), asthenia was less frequent (OR=0.3 [0.1; 0.9]; P=0.03), pleural liquid was more purulent (OR=40.0 [15.0; 106.7]; P<0.01). The blood neutrophil count was more frequently raised in cases of PIB (OR=2.5 [1.2; 5.4]; P=0.02). Pneumothorax/hydropneumothorax was less frequent in PIB (OR=0.3 [0.1; 1.0]; P=0.04). CONCLUSION: Clinical differences exist between pleural effusions caused by tuberculosis (TB) and those due to other bacterial infections. However, they are not sufficiently sensitive and therefore the search for the tuberculous bacillus must be systematic while waiting for implementation of new diagnostic tests for the organism.
