Histopathological features are vital in risk assessment, selection of treatment and prognostication in breast cancer patients. This study aimed to assess the histopathological features of all breast cancer cases seen in a tertiary hospital in the year 2018. Methods: This is a retrospective review of all breast cancer cases histologically diagnosed and confirmed by three Pathologists at the University College Hospital (UCH), Ibadan over a one-year period from 1st January 2018 to 31st December, 2018. Results: A total of 236 breast cancer cases were seen during this period, 234 (99.2%) were females while only 2 (0.8%) were male. 163 (69.7%) patients were between the fourth and sixth decades of life, 65 (27.8%) patients were above sixth decade while 6 (2.5%) patients were below fourth decade. Invasive ductal carcinoma of No Special Type (NST) was the commonest histological subtype 212 (89.8%). Grade 1 cases were 25(10.6%), Grade 2 129 (54.7%) and Grade 3 cases were 40 (16.9%) while 42 (17.8%) were not graded. Lymphovascular invasion observed in 98 (41.5%) of the cases. 54 (22.9%) had immunohistochemistry out of which 23 (43.4%) were triple negative while 8 (3.4%) were triple positive. Conclusion: Histopathological features suggesting aggressive disease was predominantly observed. Efforts should be made towards early diagnosis, adequate evaluation and prompt treatment. Cancer care should be fully incorporated in the National Health Insurance Scheme (NHIS).","PeriodicalId":16477,"journal":{"name":"Journal of Medicine in the Tropics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87925678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the lung function and the monitoring strategies of children with physician-diagnosed asthma. Methods: Children aged 6 to 18 years attending the respiratory clinic with physician-diagnosed asthma were studied. Clinical status and asthma monitoring strategies were obtained followed by spirometry. The tools used for monitoring asthma included symptom diary, peak expiratory flow meter, exacerbations, and use of rescue bronchodilator in the past 1 year. Results: There were 45 children aged between 6 and 18 years with 29 (64.4%) females and 16 (35.6%) males. There was no seasonal variation in the development of symptoms and most of the parents and siblings had no allergic conditions. Nearly all children did not use monitoring tools; none of them kept a symptom diary and only one (2.2%) and three (6.7%) had an action plan and peak flow meter, respectively. Only one (2.2%) had a history of being admitted to the intensive care unit (ICU). Thirty-three (73.3%) patients had identifiable triggers (single or multiple) with cold being the most common. Eleven (24.4%) patients had the need to use a rescue bronchodilator in the past 12 months. Thirteen (28.9%) patients had an abnormal spirometric pattern and the most common being the obstructive type.

It accounts for less than 0.01% of all cystic lesions of the head and neck. Most of the intraoral cases are reported in the midline and floor of the mouth. Very rare cases are seen involving the tongue, lips, uvula, temporomandibular joint, maxillary, and buccal mucosa. The rare oral lesion is asymptomatic, but large masses present early with difficulty in breathing and swallowing. We report an uncommon case of epidermoid cyst in an infant with failure to thrive due to obstruction and inability to latch breast milk. Case report: A 40-day-old male infant presented with a large oral swelling in the floor of the mouth since birth. It measured 4 × 5 cm in size. Surgical excision with primary closure was successfully performed. The histopathological report confirmed the diagnosis of epidermoid cyst. The child recovered to full general health with no signs of recurrence. Conclusion: Oral epidermoid cyst is a rare neoplasm that may mimic dermoid cyst and teratoid tumors clinically. The treatment of choice is surgical excision; however, there is a recurrence rate of 33% and rarely transforms into malignancy.","PeriodicalId":16477,"journal":{"name":"Journal of Medicine in the Tropics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80550721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The toxicity profile of most other species has not been investigated. Consuming mushrooms gathered in the wild is risky, as most of the mushroom poisoning reported are due to accidental ingestion of poisonous mushrooms, which are often misidentified. To study the clinical characteristics of patients who got admitted with mushroom poisoning in North Eastern Indra Gandhi Regional Institute of Health and Medical Sciences (NEIGRIHMS), Shillong over the past 5 years. Methods: A retrospective study of case records of patients admitted with mushroom poisoning over 5 years in a tertiary care regional institute of northeastern India (NEIGRIHMS, Shillong) was carried out. Data collection was done using a pre-designed proforma. Results: Fifty-three patients were admitted with mushroom poisoning during the study period of 5 years (2014–2019). Maximum number (16; 30.19%) of the patients belonged to the age group of 11 to 20 years. A two and a half months old baby on breast milk is the youngest patient admitted with mushroom poisoning. Out of 53 patients with mushroom poisoning, 33 (62.26%) reported in six clusters, and 20 (37.74%) were admitted as individual mushroom poisoning patients. The majority, 40 (75.47%), of the patients survived and got discharged. Nine (16.98%) patients died due to complications of poisoning, and four (7.55%) patients left against medical advice. Most of the cases (21, 39.62%) were from Ri-Bhoi district. Most (17, 32.07%) of the mushroom poisoning occurred during the month of May, which coincided with the peak time of mushroom production in the state of Meghalaya. Conclusions: Wild mushroom is a part of routine food consumption in the tribal population of Meghalaya. Nearly 75% of the patients admitted with mushroom poisoning recovered, whereas 16.98% died due to poisoning complications.","PeriodicalId":16477,"journal":{"name":"Journal of Medicine in the Tropics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81392321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was aimed to estimate CD4 cells and plasma HIV-1 RNA viral load among antiretroviral treatment (ART)-naive populations in three HIV treatment centres in Nigeria. Methods: We conducted a cross-sectional hospital-based study of 50 adult ART-naive patients. Whole blood and plasma samples were estimated for CD4 cells and HIV RNA-1 plasma viral load respectively. Results: The median age of the study participants was 35 years and 64% were female. The median CD4 cell count was 176 cell/μl while the median HIV viral load was 158391 copies/mL. There was a significant moderately strong, negative Spearman correlation between HIV-1 plasma viral load and CD4 cell count (r = −0.5007, P = 0.0002). Female recorded relatively higher CD4 cell count and lower plasma viral load. Six percent (6%) of the ART-naïve patients had undetectable viral load. Conclusion: This study indicates the baseline plasma viral load and CD4 cell count which can affect prognosis, disease progression and transmission. The drug-naïve participants reported with undetectable plasma RNA could be ‘elite’ controllers.","PeriodicalId":16477,"journal":{"name":"Journal of Medicine in the Tropics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87739111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to audit the demography, symptoms/signs, indications, types of surgery, postoperative outcome, and histopathological evaluation of adenotonsillectomy in Makurdi, Nigeria. Methods: This was a 3-year retrospective study. Record of total surgical procedures was taken and data of patients who had adenoidectomy, tonsillectomy, or both were retrieved. The data extracted included study population demography, symptoms/signs, indication and surgery carried out, postoperative care, and histopathological reports of specimens. The primary outcomes were symptoms/signs, indication, and type of surgery, whereas postoperative management and histopathological examination findings were secondary consideration. Ethical clearance was obtained. The data were analyzed. Results: Two hundred and twenty different types of surgeries were done within the study period. Seventy-two patients (32.7%) underwent adenoid and tonsil surgeries, comprising 46 males and 26 females; age ranged from 1 to 38 years with mean age of 6.63 ±7.78 years. Majority (68.0%) of the patients were ≤5 years old. Snoring and noisy breathing were common presentations. Obstructive adenotonsillar hypertrophy at 63.9% was the most frequent indication for surgery and adenotonsillectomy constituted the most performed procedure. Postoperatively, all the patients had routine antibiotics, analgesics, and were commenced on graded oral feeds. Nine (12.5%) and six (8.3%) patients had postoperative vomiting and fever, respectively. There were no complications of hemorrhage or fatality. The patients were kept for 2 to 3 days. Histopathology results showed follicular hyperplasia (61.1%) and chronic inflammation (38.9%). Conclusion: Adenoid and tonsillar surgeries still constitute common procedures among children in Makurdi and obstructive adenotonsillar hypertrophy and its surgery is commonly encountered with satisfactory outcome. Routine histopathological examination of nonsuspicious adenoid and tonsil specimens should be discouraged.","PeriodicalId":16477,"journal":{"name":"Journal of Medicine in the Tropics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90633408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The agreement of Gene Xpert with acid-fast bacilli was determined using the sensitivity and positive predictive value of the Gene Xpert test. Association was assessed using chi-square test. Binary logistic regression was used to determine the predictors of positive Gene Xpert result. Results: A total of 1246 records were reviewed; the average age was 41 ± 19 years, and nearly half of the patients (48.6%) were female. While 264 (21.2%) were human immuno-deficiency virus (HIV) positive. Smear microscopy was positive in 118 (16.9%); 90 (13.6%) had tuberculosis (TB) detected on Gene Xpert. Those positive for smear microscopy and Gene Xpert were 21 (10.0%). The Gene Xpert detected 90 (8.3%) of the 653 with presumptive TB. The turnaround time for Gene Xpert was 24 hours. When compared to smear microscopy, Gene Xpert showed sensitivity of 45.7% (95% confidence interval [CI]: 31.7–60.1) and specificity of 98.2% (95% CI: 95.1–99.5) in all the cases and sensitivity of 50% (95% CI: 29.8–70.2) and specificity of 100% among HIV positives.
