For centuries the sea has absorbed a variety of inputs from rivers, streams, salt marshes and the atmosphere. It is generally accepted that additional limited inputs by man are unlikely to have a significant effect on the marine environment. Various control systems have been constructed to provide a framework within which the regulation of anthropogenic inputs can be achieved. These are briefly reviewed. With care, and in the light of past experience in both freshwater and marine environments, reasonable assumptions or estimations can be applied where uncertainties exist; safe limits can therefore be set for discharges. Case histories are used to illustrate the contention that it is possible to assess the assimilative capacity of a marine area to receive wastes. There is a major distinction to be drawn between contamination and pollution of the marine environment. Moreover, acknowledgement of the assimilative capacity concept in the marine environment does not automatically provide dischargers with the right to utilise that capacity either in part or to the upper limit. What it does is indicate the upper limit which must not be exceeded if pollution is to be avoided, and provide an indication to the control authority of the safety margin involved in the discharge limits they set accordingly.

Abstract Metastatic renal cell carcinoma with involvement through the pulmonary veins to the left atrium is very rare. We report the case of a 70-year-old male with metastatic renal cell carcinoma to the right lower lobe of the lung abutting the inferior pulmonary vein with extension to the left atrium without pre-operative evidence. Surgical resection was achieved through a posterolateral thoracotomy. Lung masses that abut the pulmonary veins should prompt further investigation with a pre-operative transoesophageal echocardiogram to minimize unexpected intraoperative findings.

Pulmonary ossifications have often been regarded as rare, post-mortem findings without any clinical significance. We have investigated the occurrence of pulmonary ossifications in patients undergoing thoracic procedures, and how this may affect the differential diagnosis of solitary pulmonary nodules. In addition, we have performed a literature search on the occurrence and possible pathogenesis of these ossifications. From January 2008 until August 2019, we identified pulmonary ossifications in 34 patients who underwent elective pulmonary surgery. Pre-operative imaging was unable to differentiate these ossifications from solid tumors. A definitive diagnosis was made by an experienced pathologist (VS, ML). The PubMed database was researched in December 2019 with the search terms “pulmonary ossifications”; “heterotopic ossifications”; and “solitary pulmonary nodule”. In total, 27 patients were male, with a mean age of 63 ± 12 years (age 41 to 82 on diagnosis). All lesions were identified on thoracic CT and marked for resection by a multidisciplinary team. A total of 17 patients were diagnosed with malignancy concurrent with ossifications. There was a clear predilection for the right lower lobe (12 cases, 35.3%) and most ossifications had a nodular form (70.6%). We could not identify a clear association with any other pathology, either cancerous or non-cancerous in origin. Oncologic or pulmonary comorbidities did not influence patient survival. Pulmonary ossifications are not as seldom as thought and are not just a curiosity finding by pathologists. These formations may be mistaken for a malignant space-occupying lesion, both pre-and perioperatively, as they are indistinguishable in imaging. We propose these ossifications as an underestimated addition to the differential diagnosis of a solitary pulmonary nodule.

The article describes a case of polysegmental destructive viral-bacterial pneumonia complicated with acute pulmonary abscess, pleural empyema, and pneumopleurofibrosis in a 50-year-old female patient infected with the SARS-CoV-2 virus. The first clinical, laboratory and radiological signs of purulent-necrotic inflammation appeared only 20 days after receiving a positive RT-PCR test result with a nasopharyngeal swab. A month later, an emerging abscess in the lower lobe of the right lung was diagnosed. Subsequently, it spontaneously drained into the pleural cavity.Coagulopathy with the formation of microthrombi in small pulmonary vessels is one of the causative factors of lung abscess in patients infected with the SARS-CoV-2 virus.

Introduction: Cardiac localization of hydatid disease is rare (<3%) even in endemic countries. Affection characterized by a long functional tolerance and a large clinical and paraclinical polymorphism. Serious cardiac hydatitosis because of the risk of rupture requiring urgent surgery. The diagnosis is based on serology and echocardiography. The aim of this work is to show a case of recurrent cardiac hydatid cyst discovered incidentally during a facial paralysis assessment. Methods: We report the observation of a 26-year-old woman operated on in 2012 for pericardial hydatid cyst presenting a cardiac hydatid cyst located near the abutment of the SCV discovered incidentally during an exploration for left facial paralysis: NYHA stage II dyspnea. Chest x-ray: CTI at 0.48. ECG: RSR. Echocardiography: Image of cystic appearance at the level of the abutment of the SVC. SAPP: 38 mmhg, EF: 65%. Thoracic scan: 30/27 mm cardiac hydatid cyst bulging the lateral wall of the right atrium and the trunk of the right pulmonary artery with fissured cardiac hydatid cyst of the apical segment of the right lung of the right lower lobe with multiple bilateral intra parenchymal and sub pleural nodules. The patient was operated on under CPB. Intraoperative exploration: Presence of a hard and whitish mass, about 03 / 03cm developed in the full right atrial wall opposite the entrance to the superior vena cava. Procedure: Resection of the mass removing the roof of the LA, the AIS and the wall of the RA with reconstruction of the roof of the RA by patch in Dacron and reconstruction of the IAS and the wall of the RA by a single patch in Dacron. Results: The postoperative suites were simple. Conclusion: The hydatid cyst is still a real endemic in Algeria, the cardiac location is rare but serious and can constitute a real surgical emergency, hence the importance of prevention.

Pneumonia is most common cause of respiratory distress an infection of the pulmonary parenchyma. Despite being the cause of significant morbidity and mortality, it is often misdiagnosed, mistreated, and underestimated. Pneumonia historically was Typically classified as community-acquired (CAP), hospital-acquired (HAP), or ventilator-associated (VAP). A 68-year-old male was sent to the emergency department from clinic with an oxygen saturation of 86%. She has fevers with cough and generalized weakness for one week. She had been evaluated by her primary care provider on day two of illness and was started empirically on cefixime without improvement of her symptoms. The patient arrived febrile, tachycardic, tachypneic, and hypoxic on room air with right-sided crackles on exam. Lung Ultrasound of the right lower lobe demonstrates lung hepatization, a classic finding for pneumonia. In addition, a shred sign is present with both air bronchograms and focal B lines-all suggestive of poorly aerated, consolidated lung. Authors critically evaluate the evidence for the use lung ultrasound for rapid diagnostic. It is important to understand this disease, rapid diagnostic with ultrasound and when treated promptly and effectively, these patients will rapidly recovery. Good oxygenation, intravenous Antibiotic, intravenous fluids and symptomatic treatment which should be started within minutes of the patients’ arrival to emergency department.

Background: The diaphragm is one of the most important muscles of respiration in the body separating the abdomen from the thorax. Abnormalities of the diaphragm could be congenital or acquired, morphological or functional while pulmonary infection e.g. pulmonary tuberculosis, is implicated in its etiology. Case presentation: A 63-year- old man with six weeks history of cough productive of yellowish sputum. Chest X-ray showed a uniform well-circumscribed opacity in the right lower lobe abutting on or in continuum with the right diaphragm consistent with a diaphragmatic hump. Sputum Gene Xpert was positive for Mycobacterium tuberculosis. Chest CT scan revealed bilateral lymph node enlargement with hyperdense lesions in the anterior basal segment of the right lower lobe and medial bronchopulmonary segments of the right middle lobe. He was treated for 6 months with first-line anti-tuberculosis drugs. Discussion: The incidence of the diaphragmatic hump on chest radiograph worldwide and among Nigerians is unknown. The association of diaphragmatic hump with chest infection has been well document. The association of diaphragmatic hump with pulmonary tuberculosis is uncommon. Conclusion: A high index of suspicion is needed to diagnose pulmonary tuberculosis with atypical clinical and radiological presentations. Such prompt diagnosis will aid the treatment of the disease.

<p>Foreign body sensation is a common complaint in the otorhinolaryngology emergency. Careful examination of the patient’s pharynx is mandatory, but sometimes the object is not visualized. In such scenario, it may be important to explore signs and symptoms indicating lower aerodigestive impaction. This work describes the case of a 73-year-old woman without relevant comorbidities attending to emergency care. She complained of a foreign body sensation on the right side of the throat after ingesting a meal, which motivated referral to otorhinolaryngology. Flexible transnasal nasopharyngoscopy was unremarkable and no foreign bodies were found. Auscultation was performed revealing low-pitch expiratory wheezing on her right hemithorax. The suspicion of bronchial foreign body was then raised, which was ultimately confirmed by imaging and bronchoscopy, showing an impacted pea on the right lower lobe bronchus. The stethoscope was hence determinant for detecting aspiration, by revealing consistent alterations. Its usage should be encouraged in similar scenarios, highlighting the role of this classic but sometimes forgotten tool. Importantly, higher neck/throat sensations should not exclude the possibility of a lower airway foreign body.</p>
