The effects of a 30-minute period of chest percussion and postural drainage were compared to a sham treatment (infrared lamp) in 35 patients with stable chronic bronchitis and to a period of directed coughing in 11 of these same patients. There were no differences in subjective responses or arterial blood gas levels following therapy. Spirometric studies showed small improvements over baseline values following either treatment but no difference between active and sham treatments. The volume of sputum expectorated during percussion and drainage was significantly greater than during the infrared warming (5.5 vs 1.4 ml) or during the directed coughing (9.0 vs 3.5 ml). Although chest percussion and postural drainage are effective in augmenting the volume of expectorated sputum, no significant alternations in air flow or gas exchange after two hours were demonstrated.

Between 1980 and 1989 the Children's Hospital of Antwerp admitted 954 children with signs of intoxication. In 83 cases (9%) these were due to ingestion of hydrocarbons, 17 of these 83 children (21%) had chemical pneumonia. The most frequent chemicals were turpentine, petrol and lamp oil. The main symptoms were vomiting, skin rash, coughing and fever accompanied by an infectious blood count. Roentgen abnormalities in this group were less frequent than reported in the literature. A chest X-ray immediately after admission does not always provide information about pneumonia because abnormalities may already be present, e.g. due to an acute lung condition; nevertheless it is necessary for further study, if any. An X-ray after 24 hours is indispensable to confirm or exclude chemical pneumonia. As regards treatment, only supportive therapy is possible. Pulmonary function studies after a few weeks may be useful. A survey is presented of the epidemiology, clinical findings, diagnostics, pathophysiology, symptomatic therapy, prevention and prognosis.

Accidental ingestion and aspiration of hydrocarbons in children are common. Among the various clinical and pathological manifestations of hydrocarbon (HC) poisoning, pneumonitis is the most significant and occurs in up to 40% of children, whereas formation of pneumatoceles is believed to be a rare event. We report two children with HC pneumonitis and pneumatoceles as a reversible complication after ingestion and aspiration of lamp oil with very low viscosity. Patient 1, a 21-month-old boy, started to cough and developed tachypnea, sternal retractions and mild cyanosis immediately after aspiration. Patient 2, a 24-month-old girl, was asymptomatic during the first days after the accident; subsequently, she started to cough and developed fever, dyspnea and chest pain. Chest x-ray and computed tomography revealed multiple patchy infiltrates in both cases; after several days, these confluent infiltrates developed into pneumatoceles. Both children were treated with antibiotics and steroids. They recovered within three and four weeks, respectively, with complete remission of the radiologic abnormalities and had an uneventful follow-up after discharge.

A 20-months-old girl developed a cough and became drowsy after drinking lamp oil. In the Emergency Ward, her oxygen saturation was 85%. The day after admission to hospital she showed a clinical and radiological picture of chemical pneumonia. After 3 days the patient could be discharged in good condition. The most important symptoms after the ingestion of hydrocarbon compounds such as lamp oil are respiratory problems due to aspiration and effects on the central nervous system following gastrointestinal absorption. Severe symptoms can develop in a short period of time. The treatment is supportive. The prognosis is favourable.

Sjogren's syndrome is associated with chronic cough, but sicca symptoms are missing from cough evaluation guidelines. We evaluated patients with unexplained cough for undiagnosed Sjogren's syndrome. Patients referred to our pulmonary clinic (Sheba Medical Center, 2009 to 2012) with unexplained cough and concomitant dry eyes were selected for evaluation. Unexplained cough was defined as chronic cough of unknown etiology despite algorithm-based evaluation and treatment. Patients were evaluated in a dedicated clinic by a pulmonologist, rheumatologist, and ophthalmologist specializing in autoimmune disease. Patients completed the Leicester Cough Questionnaire, spirometry, antibody testing for anti Ro/La, ophthalmologic examination with visual acuity, eyelid, ocular surface fluorescein staining, tear break-up time and Schirmer's test, full slit lamp, and fundus examinations. Four-year follow-up was conducted by telephone questionnaire. We identified 24 patients among which 22 (21 females) agreed for evaluation. Eight patients (36%), seven initially, and one during follow-up were diagnosed with Sjogren's syndrome (SS) (six secondary and two primary SS). At 4-year follow-up, cough tended to persist and improve in only 37% with SS. These include 2 (Scl and RA) who received rituximab and 1 (stage 1 sarcoidosis) with spontaneous improvement. In contrast, cough improved in most (64%) patients without SS; the majority (eight/nine) report intensified disease-specific treatment (five allergic and three GERD). We describe patients in whom unexplained chronic cough was associated with dry eyes. Focused workup revealed undiagnosed Sjogren's syndrome in 36%. Dry eyes, with or without SS, is under-recognized and should be added to diagnostic algorithms for unexplained cough.

Coronavirus disease 2019 (COVID-19) is caused by a highly contagious RNA virus termed as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Ophthalmologists are at high-risk due to their proximity and short working distance at the time of slit-lamp examination. Eye care professionals can be caught unaware because conjunctivitis may be one of the first signs of COVID-19 at presentation, even precluding the emergence of additional symptoms such as dry cough and anosmia. Breath and eye shields as well as N95 masks, should be worn while examining patients with fever, breathlessness, or any history of international travel or travel from any hotspot besides maintaining hand hygiene. All elective surgeries need to be deferred. Adults or children with sudden-onset painful or painless visual loss, or sudden-onset squint, or sudden-onset floaters or severe lid oedema need a referral for urgent care. Patients should be told to discontinue contact lens wear if they have any symptoms of COVID-19. Cornea retrieval should be avoided in confirmed cases and suspects, and long-term preservation medium for storage of corneas should be encouraged. Retinal screening is unnecessary for coronavirus patients taking chloroquine or hydroxychloroquine as the probability of toxic damage to the retina is less due to short-duration of drug therapy. Tele-ophthalmology and artificial intelligence should be preferred for increasing doctor-patient interaction.

A 5-year-old child having infantile esotropia with bilateral inferior oblique over action underwent uncomplicated strabismus surgery. On the first postoperative day, the child was orthophoric but on day 10, the child was brought with the complaints of severe pain and redness along the original insertion of left medial rectus muscle. Immediate medical management was initiated after appropriate microbiological sampling. Subsequently, on day 13, patient developed sudden discomfort after a bout of violent cough followed by severe pain and discomfort. Slit-lamp examination confirmed the scleral wound dehiscence with vitreous prolapse for which early scleral patch graft within 6 h was performed to achieve optimal visual and cosmetic outcomes.
